Title: Systems and methods of alert generation

Description:
BACKGROUND 
     This application relates to the field data transmission and network optimization. 
     A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other along network links (data connections). The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. 
     Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. 
     Computer networks differ in the transmission media used to carry their signals, the communications protocols to organize network traffic, the network&#39;s size, topology and organizational intent. In most cases, communications protocols are layered on (i.e. work using) other more specific or more general communications protocols, except for the physical layer that directly deals with the transmission media.

     DETAILED DESCRIPTION 
     The ensuing description provides illustrative embodiment(s) only and is not intended to limit the scope, applicability or configuration of the disclosure. Rather, the ensuing description of the illustrative embodiment(s) will provide those skilled in the art with an enabling description for implementing a preferred exemplary embodiment. It is understood that various changes can be made in the function and arrangement of elements without departing from the spirit and scope as set forth in the appended claims. 
     With reference now to  FIG. 1 , a block diagram is shown illustrating various components of a content distribution network (CDN)  100  which implements and supports certain embodiments and features described herein. Content distribution network  100  may include one or more content management servers  102 . As discussed below in more detail, content management servers  102  may be any desired type of server including, for example, a rack server, a tower server, a miniature server, a blade server, a mini rack server, a mobile server, an ultra-dense server, a super server, or the like, and may include various hardware components, for example, a motherboard, a processing units, memory systems, hard drives, network interfaces, power supplies, etc. Content management server  102  may include one or more server farms, clusters, or any other appropriate arrangement and/or combination or computer servers. Content management server  102  may act according to stored instructions located in a memory subsystem of the server  102 , and may run an operating system, including any commercially available server operating system and/or any other operating systems discussed herein. 
     The content distribution network  100  may include one or more data store servers  104 , such as database servers and file-based storage systems. The database servers  104  can access data that can be stored on a variety of hardware components. These hardware components can include, for example, components forming tier  0  storage, components forming tier  1  storage, components forming tier  2  storage, and/or any other tier of storage. In some embodiments, tier  0  storage refers to storage that is the fastest tier of storage in the database server  104 , and particularly, the tier  0  storage is the fastest storage that is not RAM or cache memory. In some embodiments, the tier  0  memory can be embodied in solid state memory such as, for example, a solid-state drive (SSD) and/or flash memory. 
     In some embodiments, the tier  1  storage refers to storage that is one or several higher performing systems in the memory management system, and that is relatively slower than tier  0  memory, and relatively faster than other tiers of memory. The tier  1  memory can be one or several hard disks that can be, for example, high-performance hard disks. These hard disks can be one or both of physically or communicatingly connected such as, for example, by one or several fiber channels. In some embodiments, the one or several disks can be arranged into a disk storage system, and specifically can be arranged into an enterprise class disk storage system. The disk storage system can include any desired level of redundancy to protect data stored therein, and in one embodiment, the disk storage system can be made with grid architecture that creates parallelism for uniform allocation of system resources and balanced data distribution. 
     In some embodiments, the tier  2  storage refers to storage that includes one or several relatively lower performing systems in the memory management system, as compared to the tier  1  and tier  2  storages. Thus, tier  2  memory is relatively slower than tier  1  and tier  0  memories. Tier  2  memory can include one or several SATA-drives or one or several NL-SATA drives. 
     In some embodiments, the one or several hardware and/or software components of the database server  104  can be arranged into one or several storage area networks (SAN), which one or several storage area networks can be one or several dedicated networks that provide access to data storage, and particularly that provides access to consolidated, block level data storage. A SAN typically has its own network of storage devices that are generally not accessible through the local area network (LAN) by other devices. The SAN allows access to these devices in a manner such that these devices appear to be locally attached to the user device. 
     Data stores  104  may comprise stored data relevant to the functions of the content distribution network  100 . Illustrative examples of data stores  104  that may be maintained in certain embodiments of the content distribution network  100  are described below in reference to  FIG. 3 . In some embodiments, multiple data stores may reside on a single server  104 , either using the same storage components of server  104  or using different physical storage components to assure data security and integrity between data stores. In other embodiments, each data store may have a separate dedicated data store server  104 . 
     Content distribution network  100  also may include one or more user devices  106  and/or supervisor devices  110 . User devices  106  and supervisor devices  110  may display content received via the content distribution network  100 , and may support various types of user interactions with the content. User devices  106  and supervisor devices  110  may include mobile devices such as smartphones, tablet computers, personal digital assistants, and wearable computing devices. Such mobile devices may run a variety of mobile operating systems, and may be enabled for Internet, e-mail, short message service (SMS), Bluetooth®, mobile radio-frequency identification (M-RFID), and/or other communication protocols. Other user devices  106  and supervisor devices  110  may be general purpose personal computers or special-purpose computing devices including, by way of example, personal computers, laptop computers, workstation computers, projection devices, and interactive room display systems. Additionally, user devices  106  and supervisor devices  110  may be any other electronic devices, such as a thin-client computers, an Internet-enabled gaming systems, business or home appliances, and/or a personal messaging devices, capable of communicating over network(s)  120 . 
     In different contexts of content distribution networks  100 , user devices  106  and supervisor devices  110  may correspond to different types of specialized devices, for example, student devices and teacher devices in an educational network, employee devices and presentation devices in a company network, different gaming devices in a gaming network, etc. In some embodiments, user devices  106  and supervisor devices  110  may operate in the same physical location  107 , such as a classroom or conference room. In such cases, the devices may contain components that support direct communications with other nearby devices, such as a wireless transceivers and wireless communications interfaces, Ethernet sockets or other Local Area Network (LAN) interfaces, etc. In other implementations, the user devices  106  and supervisor devices  110  need not be used at the same location  107 , but may be used in remote geographic locations in which each user device  106  and supervisor device  110  may use security features and/or specialized hardware (e.g., hardware-accelerated SSL and HTTPS, WS-Security, firewalls, etc.) to communicate with the content management server  102  and/or other remotely located user devices  106 . Additionally, different user devices  106  and supervisor devices  110  may be assigned different designated roles, such as presenter devices, teacher devices, administrator devices, or the like, and in such cases the different devices may be provided with additional hardware and/or software components to provide content and support user capabilities not available to the other devices. 
     The content distribution network  100  also may include a privacy server  108  that maintains private user information at the privacy server  108  while using applications or services hosted on other servers. For example, the privacy server  108  may be used to maintain private data of a user within one jurisdiction even though the user is accessing an application hosted on a server (e.g., the content management server  102 ) located outside the jurisdiction. In such cases, the privacy server  108  may intercept communications between a user device  106  or supervisor device  110  and other devices that include private user information. The privacy server  108  may create a token or identifier that does not disclose the private information and may use the token or identifier when communicating with the other servers and systems, instead of using the user&#39;s private information. 
     As illustrated in  FIG. 1 , the content management server  102  may be in communication with one or more additional servers, such as a content server  112 , a user data server  112 , and/or an administrator server  116 . Each of these servers may include some or all of the same physical and logical components as the content management server(s)  102 , and in some cases, the hardware and software components of these servers  112 - 116  may be incorporated into the content management server(s)  102 , rather than being implemented as separate computer servers. 
     Content server  112  may include hardware and software components to generate, store, and maintain the content resources for distribution to user devices  106  and other devices in the network  100 . For example, in content distribution networks  100  used for professional training and educational purposes, content server  112  may include data stores of training materials, presentations, plans, syllabi, reviews, evaluations, interactive programs and simulations, course models, course outlines, and various training interfaces that correspond to different materials and/or different types of user devices  106 . In content distribution networks  100  used for media distribution, interactive gaming, and the like, a content server  112  may include media content files such as music, movies, television programming, games, and advertisements. 
     User data server  114  may include hardware and software components that store and process data for multiple users relating to each user&#39;s activities and usage of the content distribution network  100 . For example, the content management server  102  may record and track each user&#39;s system usage, including their user device  106 , content resources accessed, and interactions with other user devices  106 . This data may be stored and processed by the user data server  114 , to support user tracking and analysis features. For instance, in the professional training and educational contexts, the user data server  114  may store and analyze each user&#39;s training materials viewed, presentations attended, courses completed, interactions, evaluation results, and the like. The user data server  114  may also include a repository for user-generated material, such as evaluations and tests completed by users, and documents and assignments prepared by users. In the context of media distribution and interactive gaming, the user data server  114  may store and process resource access data for multiple users (e.g., content titles accessed, access times, data usage amounts, gaming histories, user devices and device types, etc.). 
     Administrator server  116  may include hardware and software components to initiate various administrative functions at the content management server  102  and other components within the content distribution network  100 . For example, the administrator server  116  may monitor device status and performance for the various servers, data stores, and/or user devices  106  in the content distribution network  100 . When necessary, the administrator server  116  may add or remove devices from the network  100 , and perform device maintenance such as providing software updates to the devices in the network  100 . Various administrative tools on the administrator server  116  may allow authorized users to set user access permissions to various content resources, monitor resource usage by users and devices  106 , and perform analyses and generate reports on specific network users and/or devices (e.g., resource usage tracking reports, training evaluations, etc.). 
     The content distribution network  100  may include one or more communication networks  120 . Although only a single network  120  is identified in  FIG. 1 , the content distribution network  100  may include any number of different communication networks between any of the computer servers and devices shown in  FIG. 1  and/or other devices described herein. Communication networks  120  may enable communication between the various computing devices, servers, and other components of the content distribution network  100 . As discussed below, various implementations of content distribution networks  100  may employ different types of networks  120 , for example, computer networks, telecommunications networks, wireless networks, and/or any combination of these and/or other networks. 
     The content distribution network  100  may include one or several navigation systems or features including, for example, the Global Positioning System (“GPS”), GALILEO, or the like, or location systems or features including, for example, one or several transceivers that can determine location of the one or several components of the content distribution network  100  via, for example, triangulation. All of these are depicted as navigation system  122 . 
     In some embodiments, navigation system  122  can include or several features that can communicate with one or several components of the content distribution network  100  including, for example, with one or several of the user devices  106  and/or with one or several of the supervisor devices  110 . In some embodiments, this communication can include the transmission of a signal from the navigation system  122  which signal is received by one or several components of the content distribution network  100  and can be used to determine the location of the one or several components of the content distribution network  100 . 
     With reference to  FIG. 2 , an illustrative distributed computing environment  200  is shown including a computer server  202 , four client computing devices  206 , and other components that may implement certain embodiments and features described herein. In some embodiments, the server  202  may correspond to the content management server  102  discussed above in  FIG. 1 , and the client computing devices  206  may correspond to the user devices  106 . However, the computing environment  200  illustrated in  FIG. 2  may correspond to any other combination of devices and servers configured to implement a client-server model or other distributed computing architecture. 
     Client devices  206  may be configured to receive and execute client applications over one or more networks  220 . Such client applications may be web browser based applications and/or standalone software applications, such as mobile device applications. Server  202  may be communicatively coupled with the client devices  206  via one or more communication networks  220 . Client devices  206  may receive client applications from server  202  or from other application providers (e.g., public or private application stores). Server  202  may be configured to run one or more server software applications or services, for example, web-based or cloud-based services, to support content distribution and interaction with client devices  206 . Users operating client devices  206  may in turn utilize one or more client applications (e.g., virtual client applications) to interact with server  202  to utilize the services provided by these components. 
     Various different subsystems and/or components  204  may be implemented on server  202 . Users operating the client devices  206  may initiate one or more client applications to use services provided by these subsystems and components. The subsystems and components within the server  202  and client devices  206  may be implemented in hardware, firmware, software, or combinations thereof. Various different system configurations are possible in different distributed computing systems  200  and content distribution networks  100 . The embodiment shown in  FIG. 2  is thus one example of a distributed computing system and is not intended to be limiting. 
     Although exemplary computing environment  200  is shown with four client computing devices  206 , any number of client computing devices may be supported. Other devices, such as specialized sensor devices, etc., may interact with client devices  206  and/or server  202 . 
     As shown in  FIG. 2 , various security and integration components  208  may be used to send and manage communications between the server  202  and user devices  206  over one or more communication networks  220 . The security and integration components  208  may include separate servers, such as web servers and/or authentication servers, and/or specialized networking components, such as firewalls, routers, gateways, load balancers, and the like. In some cases, the security and integration components  208  may correspond to a set of dedicated hardware and/or software operating at the same physical location and under the control of same entities as server  202 . For example, components  208  may include one or more dedicated web servers and network hardware in a datacenter or a cloud infrastructure. In other examples, the security and integration components  208  may correspond to separate hardware and software components which may be operated at a separate physical location and/or by a separate entity. 
     Security and integration components  208  may implement various security features for data transmission and storage, such as authenticating users and restricting access to unknown or unauthorized users. In various implementations, security and integration components  208  may provide, for example, a file-based integration scheme or a service-based integration scheme for transmitting data between the various devices in the content distribution network  100 . Security and integration components  208  also may use secure data transmission protocols and/or encryption for data transfers, for example, File Transfer Protocol (FTP), Secure File Transfer Protocol (SFTP), and/or Pretty Good Privacy (PGP) encryption. 
     In some embodiments, one or more web services may be implemented within the security and integration components  208  and/or elsewhere within the content distribution network  100 . Such web services, including cross-domain and/or cross-platform web services, may be developed for enterprise use in accordance with various web service standards, such as RESTful web services (i.e., services based on the Representation State Transfer (REST) architectural style and constraints), and/or web services designed in accordance with the Web Service Interoperability (WS-I) guidelines. Some web services may use the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol to provide secure connections between the server  202  and user devices  206 . SSL or TLS may use HTTP or HTTPS to provide authentication and confidentiality. In other examples, web services may be implemented using REST over HTTPS with the OAuth open standard for authentication, or using the WS-Security standard which provides for secure SOAP messages using XML encryption. In other examples, the security and integration components  208  may include specialized hardware for providing secure web services. For example, security and integration components  208  may include secure network appliances having built-in features such as hardware-accelerated SSL and HTTPS, WS-Security, and firewalls. Such specialized hardware may be installed and configured in front of any web servers, so that any external devices may communicate directly with the specialized hardware. 
     Communication network(s)  220  may be any type of network familiar to those skilled in the art that can support data communications using any of a variety of commercially-available protocols, including without limitation, TCP/IP (transmission control protocol/Internet protocol), SNA (systems network architecture), IPX (Internet packet exchange), Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocols, Hyper Text Transfer Protocol (HTTP) and Secure Hyper Text Transfer Protocol (HTTPS), Bluetooth®, Near Field Communication (NFC), and the like. Merely by way of example, network(s)  220  may be local area networks (LAN), such as one based on Ethernet, Token-Ring and/or the like.

     A model data store  309 , also referred to herein as a model database  309  can store information relating to one or several predictive models. In some embodiments, these one or several models can include one or several models that can be used to calculate one or several model functions values. In some embodiments, these one or several model function values can be used to calculate a risk probability, which risk probability can characterize the risk of a user such as a student-user failing to achieve a desired outcome such as, for example, failing to achieve a desired level of completion of a program, for example in a pre-defined time period. In some embodiments, the risk probability can identify the risk of the student-user failing to complete 60% of the program. 
     In some embodiments, these models can include a plurality of model functions including, for example, a first model function, a second model function, a third model function, and a fourth model function. In some embodiments, some or all of the model functions can be associated with a portion of the program such as, for example a completion stage and/or completion status of the program. In one embodiment, for example, the first model function can be associated with a first completion status, the second model function can be associated with a second completion status, the third model function can be associated with a third completion status, and the fourth model function can be associated with a fourth completion status. In some embodiments, these completion statuses can be selected such that some or all of these completion statuses are less than the desired level of completion of the program. Specifically, in some embodiments, these completion status can be selected to all be at less than 60% completion of the program, and more specifically, in some embodiments, the first completion status can be at 20% completion of the program, the second completion status can be at 30% completion of the program, the third completion status can be at 40% completion of the program, and the fourth completion status can be at 50% completion of the program. Similarly, any desired number of model functions can be associated with any desired number of completion statuses. 
     In some embodiments, and as will be discussed at greater length below, a model function can be selected from the plurality of model functions based on a student-user&#39;s progress through a program. In some embodiments, the student-user&#39;s progress can be compared to one or several status trigger thresholds, each of which status trigger thresholds can be associated with one or more of the model functions. If one of the status triggers is triggered by the student-user&#39;s progress, the corresponding one or several model functions can be selected. 
     The model functions can comprise a variety of types of models and/or functions. In some embodiments, each of the model functions outputs a function value that can be used in calculating a risk probability. This function value can be calculated by performing one or several mathematical operations on one or several values indicative of one or several user attributes and/or user parameters, also referred to herein as program status parameters. In some embodiments, each of the model functions can use the same program status parameters, and in some embodiments, the model functions can use different program status parameters. In some embodiments, the model functions use different program status parameters when at least one of the model functions uses at least one program status parameter that is not used by others of the model functions. 
     In some embodiments, these user parameters can identify, for the level of student-user interaction and/or involvement in one or several programs. These parameters can include, for example, the number of successful encounters and/or the number of successful encounters per day, the amount of time since a student-user&#39;s last activity, and specifically whether the amount of time since the last activity is greater than or less than 40 days, the fraction of completed lessons and/or activities, the initial stage and/or level of the student-user at the start of the program, and/or the total number units in the program. These parameters can further include, for example: an activity score parameter; a booked first encounter; a booked next encounter; cancelled encounters; center identify; repeated end-of lesson activities; end-of lesson score; first encounter result; lesson completion speed; longest break between activities; missed encounter; number of active student-users in the center; number of complementary activities; number of contracted units; number of encounters per month; number of long activity breaks; percent intro program duration period; unit completion percentage; priority; renewal status; risk estimates; starting stage; time between booking encounter and having encounter; time since last activity; time since last encounter; time to first encounter; time to first lesson; time to unit completion; and unsuccessful encounters. 
     In some embodiments, an encounter can be an interaction between a student-user and a supervisor in which content from the content distribution network  100  is consumed. In some embodiments, this can include one or several lessons, activities, tests, quizzes, or the like that can be performed during an interaction between a student-user and a supervisor. In some embodiments, determining the number of successful encounters can include identifying a program, identifying encounters within that program, determining which of the encounters in the program have been successfully completed by the student-user such as by, for example, retrieving evaluation data for completed encounters and comparing the evaluation data to a success threshold, determining the number of days since the student-user started the program, and dividing the number of successful encounters for the student-user by the number of days since the student-user started the program. 
     In some embodiments, an activity can include any interaction with the content distribution network  100 , and specifically with content form the content distribution network  100 . In some embodiments, a first value such as a “1” can be associated with a student-user when more than a specified number of days such as forty days, has passed since the last activity and a second value such as a “0” can be associated with a student-user when less than a specified number of days such as forty days, has passed since the last activity. 
     In some embodiments, the fraction of completed lessons and/or activities can be the number of completed lessons and/or activities divided by the total number of lessons and/or activities in the program and/or that the student-user has contracted for. In some embodiments, the completion of a lesson and/or activity occurs when all of the content associated with the lesson and/or activity has been consumed and/or when a final assessment associated with the lesson and/or activity has been completed. 
     In some embodiments, the initial stage and/or level of the student-user at the start of the program can identify a skill level of the student-user at the time of the start of the program. In some embodiments, this skill level can be ascertained via, for example, one or several assessments. In some embodiments, a threshold can delineate between start levels associated with greater risk and start levels associated with lesser risk. In some embodiments, a start value associated with a greater risk can be assigned a first value, such as a “1,” and a start value associated with a lesser risk can be assigned and/or associated with a second value, such as a “2.” 
     In some embodiments, the total number of units in the program can identify the size of the user&#39;s program. In some embodiments, for example, the user can control the size of the program by, for example, electing more or fewer units for inclusion in the program. In some embodiments, a parameter based on the total number of units can be calculated by taking the total number of units for a user and multiplying the total number of units by a value such as, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, and/or any other or intermediate value. 
     A threshold database  310 , also referred to herein as a threshold database, can store one or several threshold values. These one or several threshold values can delineate between states or conditions. In one exemplary embodiments, for example, a threshold value can delineate between an acceptable user performance and an unacceptable user performance, between content appropriate for a user and content that is inappropriate for a user, between risk levels, or the like. 
     In addition to the illustrative data stores described above, data store server(s)  104  (e.g., database servers, file-based storage servers, etc.) may include one or more external data aggregators  311 . External data aggregators  311  may include third-party data sources accessible to the content management network  100 , but not maintained by the content management network  100 . External data aggregators  311  may include any electronic information source relating to the users, content resources, or applications of the content distribution network  100 . For example, external data aggregators  311  may be third-party data stores containing demographic data, education related data, consumer sales data, health related data, and the like. Illustrative external data aggregators  311  may include, for example, social networking web servers, public records data stores, learning management systems, educational institution servers, business servers, consumer sales data stores, medical record data stores, etc. Data retrieved from various external data aggregators  311  may be used to verify and update user account information, suggest user content, and perform user and content evaluations.

In some embodiments, the content customization system  402  may adjust the selection and adaptive capabilities of content resources to match the needs and desires of the users receiving the content. For example, the content customization system  402  may query various data stores and servers  104  to retrieve user information, such as user preferences and characteristics (e.g., from a user profile data store  301 ), user access restrictions to content recourses (e.g., from a content access data store  306 ), previous user results and content evaluations (e.g., from an evaluation data store  308 ), and the like. Based on the retrieved information from data stores  104  and other data sources, the content customization system  402  may modify content resources for individual users. 
     A content management server  102  also may include a user management system  404 . The user management system  404  may be implemented using dedicated hardware within the content distribution network  100  (e.g., a user management server  404 ), or using designated hardware and software resources within a shared content management server  102 . In some embodiments, the user management system  404  may monitor the progress of users through various types of content resources and groups, such as media compilations, courses or curriculums in training or educational contexts, interactive gaming environments, and the like. For example, the user management system  404  may query one or more databases and/or data store servers  104  to retrieve user data such as associated content compilations or programs, content completion status, user goals, results, and the like. 
     A content management server  102  also may include an evaluation system  406 . The evaluation system  406  may be implemented using dedicated hardware within the content distribution network  100  (e.g., an evaluation server  406 ), or using designated hardware and software resources within a shared content management server  102 . The evaluation system  406  may be configured to receive and analyze information from user devices  106 . For example, various ratings of content resources submitted by users may be compiled and analyzed, and then stored in a data store (e.g., a content library data store  303  and/or evaluation data store  308 ) associated with the content. In some embodiments, the evaluation server  406  may analyze the information to determine the effectiveness or appropriateness of content resources with, for example, a subject matter, an age group, a skill level, or the like. In some embodiments, the evaluation system  406  may provide updates to the content customization system  402  or the user management system  404 , with the attributes of one or more content resources or groups of resources within the network  100 . The evaluation system  406  also may receive and analyze user evaluation data from user devices  106 , supervisor devices  110 , and administrator servers  116 , etc. For instance, evaluation system  406  may receive, aggregate, and analyze user evaluation data for different types of users (e.g., end users, supervisors, administrators, etc.) in different contexts (e.g., media consumer ratings, trainee or student comprehension levels, teacher effectiveness levels, gamer skill levels, etc.). 
     A content management server  102  also may include a content delivery system  408 . The content delivery system  408  may be implemented using dedicated hardware within the content distribution network  100  (e.g., a content delivery server  408 ), or using designated hardware and software resources within a shared content management server  102 . The content delivery system  408  may receive content resources from the content customization system  402  and/or from the user management system  404 , and provide the resources to user devices  106 . The content delivery system  408  may determine the appropriate presentation format for the content resources based on the user characteristics and preferences, and/or the device capabilities of user devices  106 . If needed, the content delivery system  408  may convert the content resources to the appropriate presentation format and/or compress the content before transmission.

In some embodiments, the communication network  120  can comprise a single intermediate hub  604 , and in some embodiments, the communication network  120  can comprise a plurality of intermediate hubs. In one embodiment, for example, and as depicted in  FIG. 6 , the communication network  120  includes a first intermediate hub  604 -A and a second intermediate hub  604 -B. 
     With reference now to  FIG. 7 , a block diagram illustrating one embodiment of user device  106  and supervisor device  110  communication is shown. In some embodiments, for example, a user may have multiple devices that can connect with the content distribution network  100  to send or receive information. In some embodiments, for example, a user may have a personal device such as a mobile device, a Smartphone, a tablet, a Smartwatch, a laptop, a PC, or the like. In some embodiments, the other device can be any computing device in addition to the personal device. This other device can include, for example, a laptop, a PC, a Smartphone, a tablet, a Smartwatch, or the like. In some embodiments, the other device differs from the personal device in that the personal device is registered as such within the content distribution network  100  and the other device is not registered as a personal device within the content distribution network  100 . 
     Speaking specifically with respect to  FIG. 7 , the user device  106  can include a personal user device  106 -A and one or several other user devices  106 -B. In some embodiments, one or both of the personal user device  106 -A and the one or several other user devices  106 -B can be communicatingly connected to the content management server  102  and/or to the navigation system  122 . Similarly, the supervisor device  110  can include a personal supervisor device  110 -A and one or several other supervisor devices  110 -B. In some embodiments, one or both of the personal supervisor device  110 -A and the one or several other supervisor devices  110 -B can be communicatingly connected to the content management server  102  and/or to the navigation system  122 . 
     With reference now to  FIG. 8 , a flowchart illustrating one embodiment of a process  800  for updating a parameter is shown. The process  800  can be performed by some or all of the components of the content distribution network  100 . The process  800  begins at block  802  wherein a user identifier is received. In some embodiments, the user identifier can be received from one of the user devices  106 . The user identifier can include, for example, information identifying the user, and in some embodiments, uniquely identify the user. This can include, for example, a username and password, a character string unique to the user, an IP address uniquely associated with the user, or the like. 
     After the user identifier has been received, the process  800  proceeds to block  804  wherein user data is retrieved. In some embodiments, the user data can be retrieved and/or received from the user profile database  301 . This user data can be retrieved and/or received by querying the user profile database  301  for information relating to the user identified by the user identifier received in block  802 . In response to this query, the user profile database can identify user data and can provide the user data to, for example, the server  102 . 
     After the user data has been retrieved, the process  800  proceeds to block  806  wherein a user data program, also referred to herein as a program or a user program is determined. In some embodiments, this can include identifying one or several programs associated with the user and/or to which the user has access. In some embodiments, these one or several programs can be identified in the user data retrieved in block  804 . 
     After the user program has been determined, the process  800  proceeds to block  808  wherein the one or several current program status parameters determined. In some embodiments, these one or several current program status parameters can relate to the users progress through the program and/or interaction with the content distribution network  100  or the content of the content distribution network  100 . In some embodiments, these one or several current program status parameters can be identified within the user data retrieved in block  804  and the current program status parameters can be determined by extracting data identifying the current program status parameters from the user data retrieved in block  804 . 
     After the current program status parameters have been determined, the process  800  proceeds to block  810  wherein one or several signals indicative of user interaction with the content distribution network  100  and/or the content thereof are received by, for example, server  102  from the user device  106 . In some embodiments, these one or several signals can comprise one or several requests for content by the user device  106 , one or several requests for participation in an activity by the user device, one or several responses from the user device  106  to content provided by the content distribution network  100 , or the like. In some embodiments, these signals can be received by the server  102  via the communication network  120 . 
     After the user interactions signals have been received, the process  800  proceeds to decision block  812  wherein it is determined whether the update a parameter. In some embodiments, this determination can include determining whether some or all of the received user interactions signals result in an update to one or several of the current program status parameters. If it is determined that none of the parameters are to be updated, the process  800  returns to block  804  and proceeds as outlined above. 
     If it is determined that one or several of the parameters are to be updated, then the process  800  proceeds to block  814  where the identified one or several parameters are updated. In some embodiments, this can include the recalculation of the parameters as discussed above with respect to the model database  309 . In some embodiments, updating the parameters can include storing the updated program status parameters as new current program status parameters in the database server  104 , and particularly in, for example, the user profile database  301 . After the program status parameters have been updated, the process  800  continues to block  816  and proceeds to block  902  of  FIG. 9 . 
     With reference now to  FIG. 9 , a flowchart illustrating one embodiment of a process  900  for generating and sending an alert is shown. The process  900  can be performed by one or several components of the content distribution network  100 . Specifically, in some embodiments, the steps of process  900  can be performed by the server  102 . The process  900  begins at block  902  wherein one or several program status parameters are received. This can include the receiving of one or several parameters from the model database  309 , which parameters can include some or all of the parameters discussed above with respect to model database  309 . In some embodiments, these one or several program status parameters can be received by the server  102  from the database server  104 , and particularly from the user profile database  301 . 
     After the program status parameters have been received, the process  900  proceeds to block  904  wherein one or several status trigger thresholds are retrieved and/or received. In some embodiments, the status trigger thresholds can identify one or several points in progression through a program at which risk probability calculations are performed. In some embodiments, these one or several status trigger thresholds can be received and/or retrieved from the database server  104 , and particularly from the threshold database  310 . 
     After the status trigger thresholds have been retrieved, the process  900  proceeds to decision block  906  wherein it is determined if a risk probability calculation is triggered. In some embodiments, this can include a comparison of one or several program status parameters to the status trigger thresholds. If it is determined that a new one of the status trigger thresholds has been reached, then a calculation can be triggered. If it is determined that a risk probability calculation has not been triggered, then the process  900  continues to block  908  and returns to block  804  of  FIG. 8 . 
     If it is determined that the risk probability calculation has been triggered, then the process  900  proceeds to block  910  wherein a model function is selected. In some embodiments, the model function can be selected by determining the model function associated with the triggered status trigger threshold. This can include querying the model database  309  and/or the threshold database  310  for information identifying the model function associated with the triggered status trigger threshold. 
     After the model function has been selected, the process  900  proceeds to block  912  wherein the model function value is calculated. In some embodiments, the model function value can be calculated by inputting one or several values associated with current program status parameters into the selected model function. After the model function value has been calculated, the process  900  proceeds to block  914  where the risk probability is calculated. In some embodiments, the calculation of the risk probability can include the retrieval of the risk probability function, the inputting of the model function value into the risk probability function, and calculating the output of the risk probability function including the model function value. In some embodiments, the risk probability can be stored in one of the databases such as, for example, the user profile database  301 . 
     In some embodiments, the calculation of the risk probability can further include determining an impact value of the one or several of the current program status parameters used in calculating the model function value. In some embodiments, this impact value can identify the relative contribution of some or all of the one or several of the current program status parameters to the overall risk probability. In some embodiments, an impact value can be calculated for each of the current program status parameters used in calculating the model function value, and the current program status parameters can then be ranked according to their calculated impact value from, for example, the current program status parameter causing the greatest increase to the calculated risk probability to the current program status parameter causing the smallest increase to the calculated risk probability. 
     After the risk probability has been calculated, the process  900  proceeds to block  916  wherein a risk threshold is retrieved. In some embodiments, the risk threshold can delineate between an acceptable risk probabilities and unacceptable risk probabilities. The risk threshold can be retrieved from the database server  104 , and can be particularly retrieved from the threshold database  310 . 
     After the risk threshold has been retrieved, the process  900  proceeds to block  918  wherein the calculated risk probability and the risk threshold are compared. In some embodiments, this comparison can determine whether the calculated risk probability is an acceptable risk probability or is an unacceptable risk probability. This comparison can be made by, for example, the server  102 . 
     After the risk probability in the risk threshold have been compared, the process  900  proceeds to decision block  920  wherein it is determined whether to generate an alert. In some embodiments, for example, an alert is generated when the comparison of the risk probability and the risk threshold indicates an unacceptable risk probability and alternatively, an alert is not generated when the comparison of the risk probability and the risk threshold indicates an acceptable risk probability. If it is determined that an alert is not to be generated, then the process  900  proceeds to block  908  and returns to block  804  of  FIG. 8 . 
     If it is determined that an alert is to be generated, the process  900  proceeds to decision block  922  where it is determined whether to generate and/or recommend an intervention. In some embodiments, this determination can be made based on information stored in the database server  104 . Specifically, in some embodiments, the user profile database  301  and/or the content library database  303  can include information indicating whether interventions should be recommended for a user and/or for a program. 
     If it is determined to generate and/or recommend an intervention, the process  900  proceeds to block  924  when a risk source identified. In some embodiments, the identification of the resource can be based on the impact values determined with the calculation the risk probability. In some embodiments, the determination of the risk source can include identifying one or several of the parameters having the greatest contribution to the increase in the risk probability. In some embodiments, this determination can be based on the relative ranking of the one or several parameters based on their impact values. 
     After the risk source has been identified, the process  900  proceeds to block  926  wherein an intervention category is identified. In some embodiments, the intervention category can comprise a group of potential interventions that can be associated with, for example, the identified risk sources. Specifically, in some embodiments the intervention category can include one or several interventions directed towards remedying deficiencies identified in one or several of the program status parameters. Intervention categories can be identified in the content library database  303 . 
     After the intervention category has been identified, the process  900  proceeds to block  928  wherein an intervention is selected. In some embodiments, the intervention can be selected from the identified intervention category. In some embodiments, for example, an intervention can be selected based on one or several user attributes such as, for example, the learning style of the user, the location of the user, or the like. 
     After the intervention has been selected, the process  900  proceeds to block  930  wherein one or several alert recipients and/or recipient devices are identified. In some embodiments, for example, one or several recipient devices can include the user device  106  associated with the student-user and/or one or several supervisor devices  110 . In some embodiments, one or several recipient devices can be selected based on location information received for the user device  106  of the student-user and based on location information received for one or several supervisor devices  110 . In some embodiments, for example in which the intervention includes personal interaction, the one or several recipient devices can be selected that are relatively most proximate to the user device  106 . In some embodiments, this determination of proximity can be made by the server  102 . 
     After the one or several alert recipients and/or recipient devices have been identified, the process  900  proceeds to block  932  wherein the alert is sent. In some embodiments, the alert can be sent to the recipient devices via the communication network  120 . Thus, in some embodiments, the alert can be sent to one or several supervisor devices  110  and/or the user device  106 . In some embodiments, the receipt of the alert can result in the launching of an application within the receiving device, and in some embodiments, the alert can include a link that, when selected, launches the application or navigates a web-browser of the device of the selector of the link to page or portal associated with the alert. 
     In some embodiments, for example, the providing of this alert can include the identification of one or several user devices  106  and/or student-user accounts associated with the student-user and/or one or several supervisor devices  110  and/or supervisor-user accounts associated with the supervisor-user. After these one or several devices  106 ,  110  and/or accounts have been identified, the providing of this alert can include determining a use location of the devices  106 ,  110  based on determining if the devices  106 ,  110  and/or accounts are actively being used. Specifically, if the user is actively using one of the devices  106 ,  110  such as the other user device  106 -B and the other supervisor device  110 -B, and/or accounts, the alert can be provided to the user via that other device  106 -B,  110 -B and/or account that is actively being used. If the user is not actively using an other device  106 -B,  110 -B and/or account, a personal device  106 -A,  110 -A device, such as a smart phone or tablet, can be identified and the alert can be provided to this personal device  106 -A,  110 -A. In some embodiments, the alert can include code to direct the default device to provide an indicator of the received alert such as, for example, an aural, tactile, or visual indicator of receipt of the alert. 
     With reference now to  FIG. 10 , a flowchart illustrating one embodiment of a process  950  for operating a supervisor device  110  is shown. The process begins at block  952 , wherein location signals are received. In some embodiments, the location signals can be received from the navigation system  122  and can be received by, for example, the communications subsystem  532 . After the location signals are received, the process  950  proceeds to block  954  wherein location data is generated. In some embodiments, the generation of location data can include the determination of the location of the supervisor device  110  based on the received location signals. In some embodiments, the location data can further include the generation of use location information identifying a use status of the supervisor device  110 , and specifically identifying whether that the supervisor device  110  is currently in use. 
     After the location data has been generated, the process  950  proceeds to block  956  where the location data is transmitted. In some embodiments, the transmission of the location data can include the transmission of the user location information. In some embodiments, this can include electronic transmission of the location data to the server  102  via the communication network  120 . After the location data has been transmitted, the process  950  proceeds block  958  wherein an alert is received. In some embodiments, the alert can be received by the supervisor device  110  from the server  102  via the communication network  120  at the communications subsystem  532 . 
     After the alert has been received, the process  950  proceeds to block  960  wherein the alert is presented to, for example, the supervisor-user. In some embodiments, the presentation of the alert can include the control of the I/O subsystem  526  to, for example, provide an aural, tactile, and/or visual indicator of the alert and/or of the receipt of the alert. In some embodiments, this can include controlling a screen of the supervisor device  110  to display the alert, data contained in alert and/or an indicator of the alert. 
     After the alert has been presented, the process  950  proceeds to block  962  wherein the alert interfaces launched. In some embodiments, the alert interface can comprise an application through which the supervisor-user can access alert data, student-user data associated with the alert, and/or any intervention data associated with the alert. After the alert interface has been launched, the process  950  proceeds to block  966  wherein control signals are generated. In some embodiments, these control signals can be generated by the I/O subsystem  526  to control one or several hardware components such as displays, screens, speakers, or the like, of the supervisor device  110  to provide the alert data to the user.

Specifically, in some embodiments the intervention category can include one or several interventions directed towards remedying deficiencies identified in one or several of the program status parameters. Intervention categories can be identified in the content library database  303 . 
     After the intervention category has been identified, the process  950  proceeds to block  972  wherein an intervention is selected. In some embodiments, the intervention can be selected from the identified intervention category. In some embodiments, for example, an intervention can be selected based on one or several user attributes such as, for example, the learning style of the user, the location of the user, or the like. 
     After the intervention has been selected, the process  950  proceeds to block  974 , wherein intervention resource data is retrieved. In some embodiments, the intervention resource data can identify resources, including human resources that can be used for the intervention. In one particular embodiment, for example, the intervention resource data can identify one or several supervisor-users who could provide and/or be involved in providing the intervention. In some embodiments, the intervention resource data can be retrieved from the database server  104 , and specifically can be retrieved from the user profile database  301 . 
     After the intervention resource data has been retrieved, the process  950  proceeds to block  976 , wherein an intervention source is identified. In some embodiments, the intervention source can be the resource, including one or several human resources that will be used in the intervention. In some embodiments in which the intervention source is a human resource, the human resource can be selected for the intervention based on, location data gathered from the supervisor device(s)  110  associated with selected human resource, location data gathered from the user device(s)  106  associated with the student-user, intervention subject matter as identified in the content library database  303 , human resource competency and/or skill level as identified in the user profile database  301 , or the like. 
     After the intervention source has been selected, the process  950  proceeds to block  978 , wherein an intervention request is transmitted. In some embodiments, this can include the transmission of the intervention request to the supervisor device (s)  110  for the intervention source selected in block  976 . In some embodiments, the intervention request can be transmitted via the communication network  120 .
