“Impact of Institutional Changes Felt by Faculty Members”: A Study with Reference to Management Institutes in Pune City
Authors: Apte Anand
Published: May 2016

Management Institutes are changing over the last decade because of competition, changes in technology, teaching pedagogy, and placement expectations from students and value for money for their parents. The next decade will bring even greater change impacting on all facets of the management institutes including major changes in infrastructure facilities, role of director, faculty members, and students of the management institutes.

Changes may take place because of placement of students, faculty member’s attitude toward students and institute etc. It is up to the management of the institute to see how effectively and smoothly these changes could be done to face competition. In this research paper an attempt has been made to know the need and types of changes required, effect of changes on faculty members and management institutes, and understanding and solving the difficulties in implementing changes in the management institutes.

For this research paper 60 faculty members were covered from management institutes in Pune. It is a descriptive research and convenience sampling was used. Primary data were collected from questionnaires. Secondary data were collected from journals, magazines, and web sites. Data analysis and hypothesis testing were done. The study revealed that faculty members like the changes made by the institute, changes are due to less admissions and adopting new technology/methodology. Difficulties/problems for implementing the changes are: Barriers in communication, interpersonal relationship, no role clarity, not understanding the necessity for change, and not accepting responsibility for change.

Authors: Sutton Shiloh , Fisher Kelsy L.
Published: May 2016

Retinoblastoma is a cancer that affects the eye, and if untreated, it can spread to other parts of the body. Retinoblastoma is the most common pediatric eye cancer and accounts for 3% of all childhood cancers. It can be hereditary or sporadic (nonhereditary). This case study presents a unilateral retinoblastoma of the right eye in a pediatric patient. A diagnosis of retinoblastoma was made by correlating sonography, magnetic resonance imaging, and ophthalmology. Treatment for retinoblastoma depends on the severity of the cancer but can include radiation, chemotherapy, focal laser therapy, and/or surgery. This particular case of retinoblastoma was treated with chemotherapy.
Bent Speech and Borrowed Selves: Substitutionary Logic and Intercessory Acts in Measure for Measure
Authors: Byker Devin
Published: May 2016

This essay explores how Shakespeare's Measure for Measure investigates the possibilities of intercessory speech and action. Intercession was a crucial and diversely realized component to many forms of late medieval religious expression, in which a person would seek the aid of another to procure his or her desires. This fundamental structure animated, for example, prayers for the dead, confession, and petitions to the saints. Yet these intercessory practices would be largely dismantled by Protestant Reformers, who argued that human intercession “darkens, and almost buries, the intercession of Christ,” as Calvin wrote. In its staging of a plot in which characters frequently depend on others to speak for them (most importantly Angelo for the Duke, and Isabella for Claudio), Measure for Measure explores the consequences of a theological insistence on speaking for oneself, while scrutinizing the capabilities and costs of an intercessory ethic.

Space, Place, & Symbol: Utilizing central places to understand intergroup conflict dynamics
Authors: Greiff Tobias
Published: May 2016

This article will present a new way of capturing highly dynamic intergroup differentiation processes through applying a spatial perspective. Drawing from my experiences collected during several field research visits to Bosnia aimed at assessing Post-Dayton intergroup relations, and inspired by the works of Doreen Massey, Michel De Certeau, and Rom Harré, I will suggest that one key to understanding how groups interpret the behavior of other groups lies in the meaning groups ascribe to the place of their interaction. With the rules of a place limiting the range of actions social agents can chose from, an understanding of ’normal’ behavior is established; which in the same second positions all other possible acts as outside the local moral order. Thus making the right to interpret a central place a favorable position and the interpretation of such a place into a strong positioning act influencing the terms of future interactions. Deciphering the dominant political meanings of central places on which intergroup interactions take place therefore becomes a promising way of understanding intergroup positioning processes. Approximating to the meanings local groups ascribe to central places, however, is in need of a thorough interpretational framework; one possible framework, based on analyzing the symbols that are used in the interpretational acts themselves, will round up this spatial approach to understanding intergroup interactions.
Potential Involvement of Draxin in the Axonal Projection of Cranial Nerves, Especially Cranial Nerve X, in the Chick Hindbrain

Published: May 2016

The appropriate projection of axons within the nervous system is a crucial component of the establishment of neural circuitry. Draxin is a repulsive axon guidance protein. Draxin has important functions in the guidance of three commissures in the central nervous system and in the migration of neural crest cells and dI3 interneurons in the chick spinal cord. Here, we report that the distribution of the draxin protein and the location of 23C10-positive areas have a strong temporal and spatial correlation. The overexpression of draxin, especially transmembrane draxin, caused 23C10-positive axon bundles to misproject in the dorsal hindbrain. In addition, the overexpression of transmembrane draxin caused abnormal formation of the ganglion crest of the IX and X cranial nerves, misprojection of some anti-human natural killer-1 (HNK-1)-stained structures in the dorsal roof of the hindbrain, and a simultaneous reduction in the efferent nerves of some motoneuron axons inside the hindbrain. Our data reveal that draxin might be involved in the fascicular projection of cranial nerves in the hindbrain.
Overview of current techniques in remote data auditing
Authors: Wu Hualong , Zhao Bo
Published: May 2016

The emergence of cloud computing brings the infinite imagination space, both in individual and organizations, due to its unprecedented advantages in the IT history: on-demand self-service, ubiquitous network access, location independent resource pooling, rapid resource elasticity, usage-based pricing and transference of risk. Many of the individuals or organizations ease the pressure on their local data storage, and mitigate the maintenance overhead of local data storage by using outsource data to cloud. However, the data outsourcing is not absolutely safe in the cloud. In order to enhance the users’ confidence of the integrity of their outsource data in the cloud. To promote the rapid deployment of cloud data storage service and regain security assurances with outsourced data dependability, many scholars tend to design the Remote Data Auditing (RDA) technique as a new concept to enable public auditability for the outsourced data in the cloud. The RDA is a useful technique to ensure the correctness of the data outsourced to cloud servers. This paper presents a comprehensive survey on techniques of remote data auditing in cloud server. Recently, more and more remote auditing approaches are categorized into the three different classes, that is, replication-based, erasure coding-based, and network coding-based to present a taxonomy. This paper also aims to the explore major issues.

A system of two oscillators with delayed pulse coupling is studied analytically and numerically. The so-called jittering regimes with non-equal inter-spike intervals are observed. The analytical conditions for the emergence of in-phase and anti-phase jittering are derived. The obtained results suggest universality of the multi-jitter instability for systems with delayed pulse coupling.
Effective Rainfall in Poorly Drained Microirrigated Citrus Orchards
Authors: Obreza T. A. , Pitts D. J.
Published: May 2016

Effective rainfall (ER) is the portion of total rainfall that plants use to help meet their consumptive water requirements, and is an important component of water resource budgeting for irrigation. The USDA's Technical Release no. 21 (TR‐21) is used to predict ER and irrigation requirements for south Florida citrus, but its accuracy is in question due to high‐intensity rainfall, poorly drained soils, and partial irrigation coverage in microirrigated orchards. We evaluated the calculation of ER by TR‐21 under these conditions by monitoring rainfall, irrigation, water table depth, evapotranspiration (ET), and soil water content inside and outside of the microirrigation‐wetted pattern in four orchards for a total of 83 site‐months. We developed a soil water budget to calculate daily water table upflux, root zone water content, water used, and ER separately for the irrigated and nonirrigated root zones. Water budget ER calculated by site ranged between −3.3% and +18.2% of TR‐21 ER, with a mean of +10%. A linear correlation between water budget ER and TR‐21 ER using pooled data from all four sites yielded the equation: Water Budget ER (mm) = 0.79 [TR‐21 ER (mm)] + 17.7, r = 0.84. A hypothetical ER comparison using 30‐yr mean rainfall and ET data showed that annual ER calculated by TR‐21 amounted to 673 mm, while water budget ER totaled 744 mm, or +10.5%. We suggest that the TR‐21 method has the level of accuracy needed to allocate water for microirrigated citrus on poorly drained south Florida soils.
Smart outlier detection of wireless sensor network
Authors: Kamal Sahar , Ramadan Rabie , El-Refai Fawzy
Published: May 2016

Data sets collected from wireless sensor networks (WSN) are usually
considered unreliable and subject to errors due to limited sensor
capabilities and hard environment resulting in a subset of the sensors data
called outlier data. This paper proposes a technique to detect outlier data
base on spatial-temporal similarity among data collected by geographically
distributed sensors. The proposed technique is able to identify an abnormal
subset of data collected by sensor node as outlier data. Moreover, the
proposed technique is able to classify this abnormal observation, an error
data set or event affected set. Simulation result shows that high detection
rate is achieved compared to conventional outlier detection techniques while
preserving low positive false alarm rate.
Keratoprosthesis: A Review of Recent Advances in the Field
Authors: Salvador-Culla Borja , Kolovou Paraskevi
Published: May 2016

Since its discovery in the years of the French Revolution, the field of keratoprostheses has evolved significantly. However, the path towards its present state has not always been an easy one. Initially discarded for its devastating complications, the introduction of new materials and the discovery of antibiotics in the last century gave new life to the field. Since then, the use of keratoprostheses for severe ocular surface disorders and corneal opacities has increased significantly, to the point that it has become a standard procedure for corneal specialists worldwide. Although the rate of complications has significantly been reduced, these can impede the long-term success, since some of them can be visually devastating. In an attempt to overcome these complications, researchers in the field have been recently working on improving the design of the currently available devices, by introducing the use of new materials that are more biocompatible with the eye. Here we present an update on the most recent research in the field.
Novel Radioligands for Cyclic Nucleotide Phosphodiesterase Imaging with Positron Emission Tomography: An Update on Developments Since 2012
Authors: Schröder Susann , Wenzel Barbara , Deuther-Conrad Winnie , Scheunemann Matthias , Brust Peter
Published: May 2016

Cyclic nucleotide phosphodiesterases (PDEs) are a class of intracellular enzymes that inactivate the secondary messenger molecules, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). Thus, PDEs regulate the signaling cascades mediated by these cyclic nucleotides and affect fundamental intracellular processes. Pharmacological inhibition of PDE activity is a promising strategy for treatment of several diseases. However, the role of the different PDEs in related pathologies is not completely clarified yet. PDE-specific radioligands enable non-invasive visualization and quantification of these enzymes by positron emission tomography (PET) in vivo and provide an important translational tool for elucidation of the relationship between altered expression of PDEs and pathophysiological effects as well as (pre-)clinical evaluation of novel PDE inhibitors developed as therapeutics. Herein we present an overview of novel PDE radioligands for PET published since 2012.

Authors: Xu Huarong , Niu Huibin , He Bosai , Cui Chang , Li Qing , Bi Kaishun
Published: May 2016

The Wu-Zhu-Yu decoction is a traditional Chinese medicine formula for the treatment of headache. To reveal its material basis, a rapid and reliable liquid chromatography-high resolution mass spectrometry method was established for comprehensive profiling of the chemical ingredients in the Wu-Zhu-Yu decoction. The method was used on a quadrupole time-of-flight mass spectrometer along with an advanced data processing procedure consisting of mass accuracy screening, mass defect filtering and fragment filtering. After eliminating interference with a filtering approach, the MS data profiling was made more distinct and accurate. With the optimized conditions of only 35 min LC separation and single sample injection of each positive or negative ion mode, a total of 168 compounds were characterized, including 23 evodiamine and its analogous alkaloids, 12 limonoids, 17 gingerols, 38 ginsenosides, 15 flavonoids, 16 organic acids, 14 alkaloids, 5 saponins, 3 2,2-dimethylchromenes and 25 other compounds. The fragmentation patterns of representative compounds were illustrated as well. Integrative qualitative analysis of the Wu-Zhu-Yu decoction by high resolution mass spectrometry was accomplished and reported for the first time. The study demonstrated that the established method was a powerful and reliable strategy for comprehensive detection and would be widely applicable for identification of complicated components from herbal prescriptions, and may provide a basis for chemical analysis of other complex mixtures.
Integrating Biodiversity Data into Botanic Collections
Authors: Horn Thomas
Published: May 2016

Today's species names are entry points into a web of publicly available knowledge and are integral parts of legislation concerning biological conservation and consumer safety. Species information usually is fragmented, can be misleading due to the existence of different names and might even be biased because of an identical name that is used for a different species. Safely navigating through the name space is one of the most challenging tasks when associating names with data and when decisions are made which name to include in legislation. Integrating publicly available dynamic data to characterise plant genetic resources of botanic gardens and other facilities will significantly increase the efficiency of recovering relevant information for research projects, identifying potentially invasive taxa, constructing priority lists and developing DNA-based specimen authentication.

To demonstrate information availability and discuss integration into botanic collections, scientific names derived from botanic gardens were evaluated using the Encyclopedia of Life, The Catalogue of Life and The Plant List. 98.5% of the names could be verified by the combined use of these providers. Comparing taxonomic status information 13 % of the cases were in disagreement. About 7 % of the verified names were found to be included in the International Union for Conservation of Nature Red List, including one extinct taxon and three taxa with the status "extinct in the wild". As second most important factor for biodiversity loss, potential invasiveness was determined. Approximately 4 % of the verified names were detected using the Global Invasive Species Information Network, including 208 invasive taxa. According to Delivering Alien Invasive Species Inventories for Europe around 20 % of the verified names are European alien taxa including 15 of the worst European invasive taxa. Considering alternative names in the data recovery process, success increased up to 18 %.

Published: May 2016

In this chapter, authors try to identify factors and enablers involved in the evolution towards a new ‘network economy' in companies, which is different from a ‘traditional economy' perspective. All these factors and enablers are gathered together and analyzed through the point of view of the processes model of a company, to decide which activities related to these factors have the highest/lowest impact and effort in the company. Benefits resulted through this change of perspective in the company are also analyzed to understand and quantify the value generated by every factor. The objectives of this chapter are: identify the factors and enablers that boost network economy in a company, understand how these factors may be introduced into the processes model of a company, and identify the percentage of the global value in the company related to every factor in the new network economy.
Approaching Leadership from a Lifelong Learning Perspective
Authors: Vives Marga , Orte Carmen , March Martí
Published: May 2016

Lifelong learning is increasingly widespread in our society. Probably, the international increase of the elderly people, as a social group, could be a key factor. In its social dimension, ageing could be conceptualized in terms of real participation and contribution of the elders on several dimensions, as, currently, on the economic factor, where elders have become the most (and sometimes the only) economic pillar in their family. This chapter is focused on the development of the lifelong learning philosophy at the Universities, specifically on the University Programs for Seniors. We would like to reflect on different intervention models and on their principal features and quantitative and qualitative indicators, as educational strategies, student's and professors' expectations, systems of evaluation, cultural adaptations,...and the methodology of the systems of evaluation (internal and/or external qualitative agencies, interviews, discussion groups, mentoring,...) framed within the best practices.
Perceptions of Teacher Education Candidates to Digital and Learning Technologies
Authors: Bull Prince Hycy , Patterson Gerrelyn Chunn , Mansaray Mahmud A. , Dunston Yolanda L.
Published: May 2016

The proliferation of learning technologies and new laws supporting digital content in K-12 education have forced teacher education programs to redefine how candidates are prepared to teach with digital content. In preparing teacher education candidates, technological knowledge is just as important as content and pedagogical knowledge. How do teacher education programs ensure that candidates are adequately prepared to teach with learning technologies and digital content? The answer to this question lies not only in the empirical knowledge of how technology is infused in the teacher education curriculum and used during student teaching, but also in the self-efficacy and the self-assessment of candidates' technological skills. Using Bandura's (1977) self-efficacy theory as a guiding framework, this study seeks to address how prepared teacher candidates are to teach with learning technologies and digital content. Findings from the study show positive efficacy of candidates to digital content and learning technologies.

Authors: Sprague Debra R. , Katradis Maria
Published: May 2016

This mixed-method study explored a cohort of 18 preservice elementary teachers' perceptions of technology and their abilities to integrate technology in their teaching. Data sources included blog postings, a confidence survey, lessons plans and observations. Results showed a disconnect between the blog postings and confidence survey (their perceptions) and their lessons plans and observations (their abilities). Five case studies were examined, using the TPACK framework, to determine where the disconnect was occurring. Although Technical Knowledge seemed to be an issue for some, the majority of the preservice teachers struggled with Pedagogical Knowledge. Suggestions for how to address this issue are included. Implications for teacher education are discussed.

The #GamerGate Files
Authors: Kidd Dustin , Turner Amanda J.
Published: May 2016

The GamerGate controversy exploded in late 2014 and seemed to pit feminist game critics against misogynistic male gamers who were defending their territory. GamerGate has been filled with intense anger on all sides, and has even resulted in threats of murder and rape. This chapter attempts to explain why so much hostility erupted over what appears to some to be a feminist critique of gaming and to others to be a misogynist-gamer critique of feminism. At heart is a surprising debate about mainstream gaming vs. indie gaming, and discomfort over changes to the notion of what counts as gaming and who counts as a gamer. The authors use online ethnographic methods to piece together the various elements of this cultural narrative from the online and social media contexts where it unfolded.
Protecting the E-Commerce Website against DDoS Attacks
Authors: Balasubramanian Kannan
Published: May 2016

A DDoS attack attempts to reduce the ability of a site to service clients, be they physical users or logical entities such as other computer systems. This can be achieved by either overloading the ability of the target network or server to handle incoming traffic or by sending network packets that cause target systems and networks to behave unpredictably. E-commerce sites are popular targets for attack for a number of reasons. The complexity of the site can reduce security coverage through human error, design fault, or immature technology implementations. E-commerce sites have a large presence and are easy to access. Defending a site against DDoS requires security teams to adopt a consistent and focused approach. In particular, staying aware of current security issues and new attack methods is of particular importance. Ensuring a reasonable security profile is an ongoing and dynamic process requiring continual refinement and consideration.

Authors: Deng Yichuan , Cheng Jack C.P.
Published: May 2016

3D Geographic Information System (GIS) models are increasingly used for planning and analyses on a city level. Defining 3D GIS city models in different levels of detail (LoD) is often needed to browse and handle large models more efficiently. In this paper, a methodology framework for automatic transformation of different LoDs in CityGML is presented and illustrated. A new exterior shell extraction algorithm was developed from the Ray Tracing algorithm for classifying building surfaces as interior or exterior. A transformation framework among each LoD was developed based on the new exterior shell extraction algorithm. The transformation framework also includes an additional LoD called LoD3.5 that the authors proposed in this paper. The new LoD can satisfy the needs of applications which require information about interior rooms while maintaining a small data storage. The results show that the new exterior shell extraction algorithm can help achieve an automatic derivation of LoDs in CityGML.

Published: May 2016

To avoid the influence of column vibration on machining precision, it is necessary to simulate the stiffness characteristics of the columns for CNC grinding machine, and to optimize the structure of the column by using sensitivity method. Based on structural characteristics of the grinding machine and structural characteristics of the columns, a finite element model is established to simulate and calculate the first-four models of the columns. In order to optimize the structure of the column, a sensitivity analysis is made to calculate the sensitivity of natural frequencies and mass of the column to each panel and ribbed plate. Considering a weighting factor and taking integrated natural frequency of the column as an optimization objective, the mass of the column as a constraint, an optimization equation is established. By a quadratic programming method, the parameter optimization of the column is got as follows: the mass decreased by 4%, integrated natural frequency increased by 2%. Dynamic stiffness of the column has been optimized by harmonic response analysis, the results showed that the largest column in the Z resonance peak reduced by 8.44%.

Authors: Wen Yi Fang , Rui Yan Nian , Wang Hong Wei
Published: May 2016

The graft polymerization in radio frequency hollow cathode plasma (RFHCP) is suitable for the surface modification of large-area thin film materials. The homogeneity of plasma surface modification of large-area thin film materials has always been paid close attention, and it is also the key factor affecting the industrialized applications of the technique. However, the homogeneity of plasma surface modification is thought to depend greatly on the distribution of discharge gas. In this paper, a finite element model is proposed to discuss the flow of discharge gas in hollow cathode plasma. The concentration distribution of the discharge gas has been discussed by the combination of numerical simulation of fluid distribution and pipe flow theory based on the investigation of the transport property of gas under vacuum. Comparisons between available experiments have also been performed to validate the applicability and practicability of the proposed model.

Research on Dynamic Behavior of Different Grinding Wheel Hub Material with FEM Method
Authors: Liu Yong Tao , Fu Yu Can , Yang Lu , Xu Jiu Hua
Published: May 2016

This paper presented a numerical model of a grinding wheel hub to analyze the dynamic behavior between CFRP hub and steel hub. Natural frequencies of the two different hubs were extracted with the help of finite element software ABAQUS. In addition, the vibration attenuation procedure in the process of free vibration of the hubs was also compared. The numerical results obtained from the model demonstrated that natural frequency of the CFRP hub is much higher than that made of steel owing to the great ratio of elastic modulus to density of carbon fiber. The CFRP hub has a better damping vibration characteristic which allows it to absorb vibration in grinding process to achieve a finer surface roughness.

As the premise, exploring aero-engine structure parts damage accurately can guarantee safety of the aero-engine structure parts, which are restricted by the working condition under the high temperature, high pressure and high speed. Analyzed the structure parts modal parameters by the modal theory, and researched the facts how to influence the modal parameters based on the different damage extent of the structure parts. Then construct the different damage extent structure models on the structure junctions with the finite element analysis method. At last, constructed and verified seven models with the example of aero-engine turbine structure damage in the constant temperature. The results were shown that the characteristic parameters with the inherent frequency and the inherent frequency deviation square can explore the structure damage accurately, but have no significant influence on the structural damages. So it will be important for us to ensure reliable operation and structure damage identification timely by the proposing the structure damage parameters.
