CreativeTeams : exploring the creative performance of co-located and virtual teams

This thesis compares the creative performance of traditional co-located and virtual teams. Motivation for this research is twofold. Firstly there is the reluctance shown by many organisations to adopt virtual working practises. Second, there is the gap in existing research ex- ploring how virtual teams collaborate synchronously when addressing complex tasks. In particular there is a lack of empirical research com- paring co-located and virtual team performance. The CreativeTeams tool has been created to address this by providing an objective method of measuring team creative performance regardless of location. Cre- ativity is assessed because it is an important socio-cognitive process, and is often key in addressing complex tasks requiring extensive team collaboration such as designing, problem solving and emergency plan- ning. Such complex tasks have traditionally been the sole domain of co-located teams. This thesis therefore provides a point of compar- ison. The tool itself incorporates a number of activities, the core of which are adapted from the Torrance Tests of Creative Thinking. A study has been run with 150 student participants, working in 50 teams. Each team completes the CreativeTeams activities in either a co-located or virtual environment. Outputs from these activities are assessed by multiple markers and analysed along with meta data from the tool. A comparison of these metrics indicates no significant differ- ence in co-located and virtual team performance across the majority of metrics. This demonstrates that virtual teams can be as effective as co-located teams in addressing complex tasks and is a key research contribution, as is the formation of the CreativeTeams tool itself.
Women in computer science. The case study of the Computer Science Department of the University of Crete, Greece

Various international researches lay emphasis on the fact that women are being under represented in the fields of technology, especially in the computer science. A recent investigation in the USA mentions that female participation in information science at academic level decreased from 28% in 2001 to 18% in 2012. Likewise, in the job market of information science, it dramatically shrunk from 36% in 1991 to 25% in 2015. Having considered the above, we wanted to investigate if, at an academic level, the same trend has been correspondingly affirmed in Greece. The analysis of the data relevant to the alumni of the Computer Science Department of the University of Crete, from 1985 since the recent academic year (2016-2017), has been discouraging since it shows a continuous and pejorative under-representation of women in the field of information science.
Internet of Threads: Processes as Internet Nodes

In the beginning, Internet and TCP/IP protocols were based on the idea of connecting computers, so the addressable entities were networking adapters. Due to the evolution of networking and Internet services, physical computers no longer have a central role. Addressing networking adapters as if they were the true ends of communication has become obsolete. Within Internet of Threads, processes can be autonomous nodes of the Internet, i.e., can have their own IP addresses, routing and QoS policies, etc. In other words, the Internet of Threads definition enables networked software appliances to be implemented. These appliances are processes able to autonomously interoperate on the network, i.e., the software counterpart of the Internet of Things’ objects. This paper will examine some usage cases of Internet of Threads, discussing the specific improvements provided by the new networking support. The implementation of the Internet of Threads used in the experiments is based on Virtual Distributed Ethernet (VDE), Contiki and View-OS. All the software presented in this paper has been released under free software licenses and is available for independent testing and evaluation. Keywords-Internet; IP networks; Virtual Machine Monitors

The Role of Work Environment on Bank Employees’ Performance

Workload and Work Environment are several factors that can affect employees’ performance in their effort to achieve organizational goals. This study aims to investigate whether workload and work environment influence bank employee’s performance. The sample of this study is 130 front liners of PT Bank Negara Indonesia (persero), Tbk Branch Office Diponegoro University Semarang taken by using proportional random sampling technique. The collected data are analyzed using multiple regression test. The result of this study prove that workload and work environment have significant effect on employees’ performance. The more appropriate the workload given to the BNI employees, the better their performance will be. A comfortable work environment physically by giving complete facilities and non-physically such as good relationship with coworkers support employees to increase their performance. Based on these findings, it can be concluded that providing workload effectively motivates employee to work better and giving a comfortable work environment improves employees’ performance. Keywords—workload; work environment; employees’ performance
Creating an Immutable Database for Secure Cloud Audit Trail and System Logging

—Conventional web based systems present a multiplicity of attack vectors. One of the main components, the database, is frequently conﬁgured incorrectly, often using default settings, which leave the system wide open to attack. Once a system has been attacked, valuable audit trail and system log data is usually deleted to cover the trail of the perpetrator. Given the average industry time between breach and discovery, there is often little forensic trail left to follow. Of equal importance is that in cloud settings, where new instances are automatically spooled and shut down to follow the demand curve, any data stored on the running instance before shut down is lost. We demonstrate how the conﬁguration of a simple immutable database, running on a separate private system can go a long way to resolving this problem.

Problems of rural extension courses in Mexico

In order to contribute to the knowledge about the problems related to the policies of rural extension courses inMexico from the perspective of the extension agents, the circumstances which hinder their work wereidentified, described and analyzed. A survey of the extension agents from the Monitoring and EvaluationCourse Component System of Extension Agents 2016, which gathered information from nine states ofthe republic. The size of the sample amounted to 308 questionnaires. The answers to open questions wereanalyzed and were categorized and quantified. The analysis was later used in relation to the qualitativevariables. The difficulties were associated with socio-demographic variables and location. Fifteen problemswere found. There are five principal ones: 1) the lack of opportunity at the beginning of service; 2) training ofextension agents with a productivist perspective; 3) precarious work for extension agents; 4) discontinuationof extension groups; and 5) the dismantling of the component with other programs. Statistically significantdifferences were found between the predominant problem and the federal entity, sex, age, experience, andthe academic training of the extension agents which permits establishing specific strategies to promote amore effective and efficient public policy, based on the recommendations of the actors who make decisionsabout extension courses at the level of the production unit.
Can Prostitution in Indonesia be Eliminated?

Previous studies have revealed a lot of personality factors to explain the negative behavior of a society. In this study, the concept of personality is adopted to predict the behavior of prostitution which is seen from the intention to leave prostitution. In addition, this study also observed Age as one of the variables conceptualized to moderate the relationship between personality and intention to leave prostitution. Data was collected through a survey of 100 respondents as the study sample, which was carried out non-randomly, because to select the target respondents need to be asked first about the possibility of leaving prostitution. The sampling area is a number of places where prostitutes are held, including in several hotels, at bus terminals or on roadside, or other places where they hang out. Surveys are carried out at night when they would start their work or during the day when they rested. Furthermore, the collected data was analyzed using Cluster Analysis to create personality groups and Hierarchical Multiple Regression Analysis to test the effect of moderation. The results indicate that on the one hand, neuroticism and consciousness are personality types that are not significantly associated with the intention to leave prostitution, and also age is not significantly associated with the intention to leave prostitution, but on the other hand it is found that Age significantly moderates the relationship between all types of personality (Extroversion, Neuroticism, Agreeableness, Consciousness, and Openness) and intentions to leave prostitution. The study also discusses insignificant results, as well as the implications of the study, as well as study limitations. Keywords—behavior of prostitution; intention to leave; personality; extroversion; neuroticism; agreeableness; consciousness; and openness

Evidence for Speech Sound Disorder (SSD) Assessment

Comprehensive studies on aspects related to the assessment of different biomedical parameters (acoustic and laryngeal signs and oral airflow amplitude), as well as param - eters for speech disorders, articulation rate, speech inconsistency, and speech stimulabil - ity, are essential for better professional practice and to understand misarticulations in children with speech sound disorders (SSDs). Different equipments that enable nonin - vasive collection and analysis of data have become more common in speech-language pathology practice. Studies recently conducted by our research group have emphasized the evaluation of auditory-perceptual processing by means of assessments of central auditory processing, electrophysiology of hearing—considering that pure-tone, speech audiometry, and tympanometry are routinely used with children during the diagnos - tic phase and motor speech production performed by acoustic analysis of speech, elec - troglottography, aerodynamic measures, and ultrasound tongue imaging. This chapter presents the recent advances observed in studies with Brazilian-Portuguese speakers aiming to improve the assessment of speech sound disorders and to understand better the relationship between the different processing mechanisms involved in speech.

Incorporating Bias-aware Margins into Contrastive Loss for Collaborative Filtering

Collaborative filtering (CF) models easily suffer from popularity bias, which makes recommendation deviate from users' actual preferences. However, most current debiasing strategies are prone to playing a trade-off game between head and tail performance, thus inevitably degrading the overall recommendation accuracy. To reduce the negative impact of popularity bias on CF models, we incorporate Bias-aware margins into Contrastive loss and propose a simple yet effective BC Loss, where the margin tailors quantitatively to the bias degree of each user-item interaction. We investigate the geometric interpretation of BC loss, then further visualize and theoretically prove that it simultaneously learns better head and tail representations by encouraging the compactness of similar users/items and enlarging the dispersion of dissimilar users/items. Over eight benchmark datasets, we use BC loss to optimize two high-performing CF models. On various evaluation settings (i.e., imbalanced/balanced, temporal split, fully-observed unbiased, tail/head test evaluations), BC loss outperforms the state-of-the-art debiasing and non-debiasing methods with remarkable improvements. Considering the theoretical guarantee and empirical success of BC loss, we advocate using it not just as a debiasing strategy, but also as a standard loss in recommender models.
The flexible use of abstract knowledge in planning

People are flexible and robust problem solvers: faced with problems that go beyond their past experience in a domain, they often find ways to cope. When domain-specific knowledge is inadequate, more general knowledge can often be brought to bear. In particular, problems that at first appears novel can often be redescribed in domain-unspecific terms and thereby revealed to be familiar at a more abstract level. Existing domain-specific knowledge may then be directly applicable to the redescribed problem. We call this approach to problem solving problem reformulation. This dissertation presents a case-based account of problem reformulation. We propose an architecture in which a case-based reasoner acts as an intelligent assistant to an automated planner. The case-based reasoner reformulates novel problems using abstract knowledge represented as culturally-shared cases. Whenever the planner lacks appropriate domain-specific knowledge, the case-based reasoner adapts an appropriate culturally-shared case to resolve the planner's difficulty. We focus on the adaptation phase of case-based reasoning. Adaptation takes as input a planner difficulty and a culturally-shared case that may resolve it, and proceeds in three stages. First, an abstract model of the planning process is used to transform the case into a planner data structure that may resolve the planner's difficulty. Second, the planner's problematic situation or initial state is redescribed to fit the abstract vocabulary of the proposed solution. Knowledge structures called viewing schemas are used to control redescription inference. Finally, the candidate solution is elaborated with relevant domain-specific knowledge that was inaccessible prior to redescription. The approach is implemented in scBRAINSTORMER, a planner that uses culturally-shared cases to help it plan. The system operates in the domain of political and military policy as it relates to terrorism. scBRAINSTORMER makes contributions in the areas of case-based reasoning, knowledge representation, automated knowledge acquisition, and model-based reasoning.
Dynamical Properties of Some Non-stationary, Non-simple Bratteli-Vershik Systems

SARAH BAILEY: Dynamical Properties of some non-stationary, non-simple Bratteli-Vershik systems (Under the direction of Professor Karl Petersen) Bratteli-Vershik systems, also called adics, are dynamical systems defined on the infinite path space of a Bratteli diagram. We introduce a family adics called limited scope adics for which the number of vertices increases by a constant at each level, and a subfamily determined by positive integer polynomials. We show that the dimension groups of the Bratteli diagrams associated to limited scope adics are intrinsically linked to the dynamics, generalizing a result for Cantor minimal systems, and we explicitly compute them for the subfamily of adics determined by a positive integer polynomials. We show that certain limited scope adics are isomorphic to subshifts. For the systems determined by positive integer polynomials we show that the set of fully-supported invariant ergodic probability measures consists of a one-parameter family of Bernoulli measures. We also show that the systems associated to positive integer polynomials are loosely Bernoulli. A particular limited scope adic system is the Euler adic system, for which the number of paths from the root vertex to a vertex (n,k) is the Eulerian number A(n,k). We show that this system has a unique fully-supported invariant ergodic probability measure and that the system is totally ergodic and loosely Bernoulli.
High Integrity Localization With Multi-Lane Camera Measurements

Localization with high integrity is crucial for highly autonomous vehicles. This requires that the localization system send a warning to a client application when it should not be used. The concept of integrity was firstly developed for aviation applications and recently became an active research area for autonomous vehicles. GNSS information merged with dead reckoning sensors is not sufficient for lane level localization in all navigation environments. Map-aided localization with vision sensors is essential to provide redundant and complementary information. In this work, a multi-sensor data fusion method that takes advantage of a high definition (HD) map is presented and the integrity of the obtained solution is quantified. A Fault Detection and Exclusion (FDE) step is added to exclude the faulty measurements from the fusion procedure. A second step is to bound the estimation errors in the Along Track (AT) and Cross Track (CT) directions through Protection Levels (PL). For this step, the usual Gaussian distribution is replaced by a Student's distribution with an adapted degree of freedom chosen according to the navigation environment. The performance of the approach is evaluated with an experimental vehicle equipped with a camera able to detect up to four lane markings simultaneously.
