The effects of hypertext in a multimedia environment on the achievements in Judaic studies of elementary and junior high school students

The Effects of Hypertext in a Multimedia Environment on the Achievements in Judaic Studies of Elementary and Junior High School Students By Yitzhak Rossler The accelerated technological development encompassing our world in every walk of life demands the attention of education professionals as to the ramifications and the effects of this development on the educational system and on teaching activities. The new technologies computer and computer communication technologies – significantly affect the process of transmission and reception of messages. In contrast to the transmission of messages in the “literary society” in which the text serves as a central means of transmission, in the information society, the computer and computer communications systems have become increasingly prevalent in serving as transmission channels. While text calls for a mainly rational treatment through the extensive use of cognitive decoding methods, the new technologies address most of the senses, in addition to the rational treatment, and enable reception of messages through the use of a variety of decoding tools. On 2002 we conducted a study aimed at investigating the impact of learning using hypertexts in a multimedia environment upon the students’ scholastic achievements. The study was implemented with pre-adolescents and adolescents who are in the transitional developmental stage from “concrete” to “formal” thinking and in the “formal” thinking stages. The study compared the learning achievements of the fourth grade students with those of the eighth grade students. Our assumptions were: Both fourth grade students and eighth grade students, at all functionality parameters, will exhibit higher scores in three cognitive parameters a. knowledge, b. comprehension and c. elaboration learned using hypertext in a multimedia environment than by conventional learning methods. Our question was: does the gender variable generate significant differences, with respect to the performance efficiency of learning with hypertext in a multimedia environment? In order to test our assumptions 2 x 2 X 2 ANOVA analyses were made with repeated measures per session. These analyses were made for the subject’s general test score as well as for the three measures of each set of questions – knowledge, comprehension, and elaboration parameter. We did find the achievements brought about through PC-aided learning were higher in all parameters. We also found that in grade eight the boys did better than girls, while in grade four the girls did better. ii The Effects of Hypertext in a Multimedia Environment on the Achievements in Judaic Studies of Elementary and Junior High School Students By: Yitzhak Rossler Kedumim, Shomron Israel Submitted in partial fulfillment of the requirements for the degree of Doctor of Education In the Azrieli Graduate School of Jewish Education and Administration Yeshiva University New York May 2003
HRTF Customization by Regression

This thesis deals with HRTF customization by regression. Five different regression approaches were investigated, implemented and compared to one another. All the regression algorithms were executed with different variations and modifications in order to find ways to improve the results. These results were then compared to both non-customized HRIRs and individually measured HRIRs, acquired at the LDV audio laboratory. The evaluation is based on spectral distortion, but the run time, the complexity and the effort of the different methods were taken into consideration as well. The goal of this thesis is to provide a wide comparison between several different possible solutions in order to provide a good foundation for further research. The results showed that the PCA’s results were the worst and that changing it to a 2DPCA improved the results significantly. GLRAM and Tensor SVD, despite better SD values, are less suited for regression as they take much longer to execute than the PCA and the 2DPCA. The best results were achieved by using the PLSR.
Evidence in Epistemic Logic : A Topological Perspective

This dissertation brings together epistemic logic and topology. It studies formal representations of the notion of evidence and its link to justification, justified belief, knowledge, and evidence-based information dynamics, by using tools from topology and (dynamic) epistemic logic. Part I is concerned with evidence-based interpretations of justified belief and knowledge. Starting with a by-now-standard topological interpretation of knowledge as the interior operator, we develop, in a gradual manner, a topological framework that (1) can talk about evidence not only semantically, but also at the syntactic level, thereby making the notion of evidence more explicit; (2) takes evidence as the most primitive notion, and defines belief and knowledge purely based on it, thereby linking these two crucial notions of epistemology at a deeper, more basic level. In Part II of this dissertation, we focus on notions of knowledge as well as various types of information dynamics comprising learning new evidence. More precisely, this part is centered around the notions of absolutely certain knowledge and know ability as "potential knowledge", as well as the connections between the abstract notion of epistemic effort encompassing any method of evidence acquisition and the well-studied dynamic attitudes such as public and arbitrary public announcements. To sum up, this dissertation on one hand re-interprets some existing epistemic and doxastic logics and their dynamic extensions from a topological perspective, providing an evidence-based interpretation. On the other hand, it uses topological tools to refine and extend earlier analysis, leading to novel logics of evidence and information dynamics
Impact of Social Networking Sites in Bangladesh: Few Possible Solutions

—Bangladesh is a developing country. But in few recent years this country is going to be turned as digitalized. The first condition of being digitalization is the whole communication system of the country have to be developed tremendously. If we notice about the communication system, then Social Networking Sites can be a platform of revolution. This study is based on the perspective of Bangladesh on Social Networking Sites(SNS). In Bangladesh, Social Networking Sites are getting popular tremendously. The Social Networking Sites(SNS) like twitter and Facebook gives people in general the useful platform for disclosure of their thinking and ideas. This research paper is made with an aim to represent the positive and negative impact of Social Networking Sites(SNS) and we will also try to recommend few possible solutions to overcome these problems.
Experiments with OpenFlow and IEEE802.11 Point-to-Point Links in a WMN

Software Defined Networking (SDN) and Wireless Mesh Networks (WMNs) evolved to be sophisticated technologies used in a variety of applications. However, a combined approach called Wireless Mesh Software Defined Network (wmSDN) has not been widely addressed in the research community. Our idea in this field consists of WiFi-based point-to-point links managed by the OpenFlow protocol. We investigate two different issues regarding this idea. First, which WiFi operational mode is suitable in an OpenFlow managed broadcast domain? Second, does the performance decrease compared with other routing or switching principles? Therefore, we set up a real-world testbed and a suitable simulation environment. Unlike previous work, we show that it is possible to use WiFi links without conducting Media Access Control (MAC) address rewriting at each hop by utilizing the 4-address-mode. Keywords–SDN; OpenFlow; WDS; wmSDN; SDWN; WiFi
Very low-cost 80-Bit chipless-RFID tags inkjet printed on ordinary paper

This paper presents a time-domain, chipless-RFID system with 80-bit tags inkjet-printed on ordinary DIN A4 paper. The tags, consisting of a linear chain of resonant elements (with as many resonators as the number of identification bits plus header bits), are read sequentially and by proximity (through near-field coupling). To this end, a transmission line, fed by a harmonic (interrogation) signal tuned to the resonance frequency of the tag resonators (or close to it), is used as a reader. Thus, during reader operation, the tag chain is mechanically shifted over the transmission line so that the coupling between the line and the functional resonant elements of the tag chain is favored. Logic states that ‘1’ and ‘0’ are determined by the functionality and non-functionality (resonator detuning), respectively, of the resonant elements of the chain. Through near-field coupling, the transmission coefficient of the line is modulated and, as a result, the output signal is modulated in amplitude (AM), which is the identification code contained in the envelope function. As long as the tags are inkjet-printed on ordinary DIN A4 paper, the cost is minimal. Moreover, such tags can be easily programmed and erased, so that identical tags can be fabricated on a large scale (and programmed at a later stage), further reducing the cost of manufacture. The reported prototype tags, with 80 bits of information plus four header bits, demonstrate the potential of this approach, which is of particular interest to secure paper applications.
The Associative Basis of Scientific Creativity: A Model Proposal

Creativity is accepted as an important part of scientific skills. Scientific creativity proceeds from a need or urge to solve a problem, and involves the production of original and useful ideas or products. Existing scientific creativity theories and tests do not feature the very important thinking processes, such as analogical and associative thinking, which can be considered crucial in creative scientific problem solving. Current study’s aim is to provide an alternative model and explicate the associative basis of scientific creativity. Emerging from the reviewed theoretical framework, Scientific Associations Model is proposed. This model claims that, similarity and mediation constitutes the basis of creativity and focuses on three components namely; associative thinking, analogical thinking (analogical reasoning & analogical problem solving) and insight which are considered to be main elements of scientific associative thinking.
Working in music with adolescents who experience disability

Working in music with adolescents who experience disability to support their health and wellbeing involves creating opportunities for their emotional expression and successful interaction with others. Music is a resource that can highlight their capabilities, yet they might need the support of a music therapist to maximize the positive affordances that music can provide. In this chapter, two contrasting examples of music therapy work, with adolescents who have attention-deficit/hyperactivity disorder (ADHD) and those who have intellectual disability, are offered to demonstrate how young people have engaged with music therapy group processes and in turn developed positive relationships and self-identities. Music making can be a motivating and enjoyable activity for adolescents with disabilities, and a powerful resource to support their personal growth, autonomy, and sense of wellbeing.
Design, Deployment, and Evaluation of Gesture-Controlled Displays in Ubiquitous Environments

We present a scalable, semi-automated process for studying the usage of public displays. The process consists of gathering anonymous interaction and skeletal data of passersby during public display deployment and programmatically analyzing the data. We demonstrate the use of the process with the analysis of the Information Wall, a gesture-controlled public information display. Information Wall was deployed in a university campus for one year and collected an extensive data set of more than 100 000 passersby. The main benefits of the process include (1) gathering of large data sets without considerable use of resources, (2) fast, semiautomated data analysis, and (3) applicability to studying the effects of long-term public display deployments. In analyzing the usage and passersby data of the Information Wall in our validation study, the main findings uncovered using the method were (i) most users were first-time users exploring the system, and not many returned to use the system again, and (ii) many users were accompanied by passive users who observed interaction from further away, which could suggest a case of multi-user interaction blindness. In the past, logged data has mainly been used as a supporting method for in situ observations and interviews, and its use has required a considerable amount of manual work. In this article, we argue that logged data analysis can be automated to complement other methods, particularly in the evaluation of long-term deployments.
Video representation by dense trajectories motion map applied to human activity recognition

ABSTRACT This paper introduces an efficient video representation method based on the dense trajectory motion map (DTM). We utilize the salient features of dense trajectories and motion descriptor to integrate the discriminative information of a video into a map. Firstly, we extract the dense trajectories features by using dense optical flow then multiple descriptors are computed along trajectories to capture appearance and motion information. This result is then integrated into frames difference to integrate entire discriminative information and motion energy to get our first motion map. For the final DTM each generated motion map will be integrated with the absolute frame difference of next two frames till the end of entire video. Finally, we process the resultant DTM by exploring the efficient long-term recurrent convolutional network module for encoding and action label generation. The developed approach is shown better and had comparable recognition results over the existing methods when applied to the publically available human action datasets.
Securing the 'Internet of Things': decentralised security for wireless networks of embedded systems

The phrase 'Internet of Things' refers to the pervasive instrumentation of physical objects with sensors and actuators, and the connection of those sensors and actuators to the Internet. These sensors and actuators are generally based on similar hardware as, and have similar capabilities to, wireless sensor network nodes. However, they operate in a completely different network environment: wireless sensor network nodes all generally belong to a single entity, whereas Internet of Things endpoints can belong to different, even competing, ones. This difference has profound implications for the design of security mechanisms in these environments. Wireless sensor network security is generally focused on defence against attack by external parties. On the Internet of Things, such an insider/outsider distinction is impossible; every entity is both an endpoint for legitimate communications, and a possible source of attack. We argue that that under such conditions, the centralised models that underpin current networking standards and protocols for embedded systems are simply not appropriate, because they require such an insider/outsider distinction. This thesis serves as an exposition in the design of decentralised security mechanisms, applied both to applications, which must perform access control, and networks, which must guarantee communications security. It contains three main contributions. The first is a threat model for Internet of Things networks. The second is BottleCap, a capability-based access control module, and an exemplar of decentralised security architecture at the application layer. The third is StarfishNet, a network-layer protocol for Internet of Things wireless networks, and a similar exemplar of decentralised security architecture at the network layer. Both are evaluated with microbenchmarks on prototype implementations; StarfishNet's association protocol is additionally validated using formal verification in the protocol verification tool Tamarin.
Performance impact of the interconnection network on MareNostrum applications

Interconnection networks are one of the fundamental components of a supercomputing facility, and one of the most expensive parts. They represent one of the main differences between two supercomputers built from the same processor, and have a significant impact on how the applications should be developed. However, very little is known about how those expensive interconnection networks are used by the real applications running on supercomputing facilities. Furthermore, in the near future, chip multiprocessors offering near supercomputing capabilities, with 64 to 256 processor per chip, will be readily available. Onchip interconnection networks offer the possibility of new designs with lower latencies and much higher bandwidths. In this paper we present an analysis of the impact of the interconnection network for some of the most representative applications running on MareNostrum, at the Barcelona Supercomputing Center. We have collected traces of real runs of the applications, and verified that our performance model (Dimemas) accurately predicts the real machine performance. Then, we present hypothetical situations where we change the network’s latency, bandwidth, number of simultaneous connections, and CPU speed in order to quantify their importance on the final application performance in the context of future on-chip interconnenctions. Our results show that the CPU speed proves more important than the interconnection network, and that among the network’s parameters, interconnection bandwidth is far more important than latency (with a very low impact), or the connectivity (only relevant for low connection bandwidth).

SATISFACTION OF DOMESTIC LEISURE TRAVEL BASED ON AGE RANGE: CASE OF JAPAN

Tourism has a large effect on lifestyle, society and the economy. With policy goals aiming to develop Japan into a tourism nation, it has become important for Japan to understand tourism trends and satisfaction. This paper focuses on tourists’ satisfaction based on age range for Japan domestic leisure travel with overnight stays by Japan residents. It examines the characteristics concerning the satisfaction of the travellers by each age range. The results find that the younger age ranges trend to be relatively “satisfied” with their travels and the older age ranges were relatively dissatisfied, with the 50s and 60s age ranges showing a strong tendency of being “very dissatisfied. ” The age range closest to the average was the 40s.
SATISFACTION WITH E-LEARNING QUALITY EXPRESSES READINESS TO DEVELOP OWN ONLINE COURSE, NOT ONLY JUST TO FURTHER STUDY ONLINE

E-learning has become an important part of contemporary educational process. Satisfaction with e-learning quality was studied among 133 Bulgarian participants in an online survey, of which more than the half took part is some e-learning courses. The results indicated that the learners for whom e-learning was a part of their education at school or university tended to do more online courses and were more satisfied with e-learning quality, so traditional education seemed to support e-learning. The participants who had been enrolled in some online courses, who had their own Internet site and who were satisfied with e-learning quality were more self-confident in their ability of developing an online course. Satisfaction with e-learning prevailed in the sample, because approximately one out of ten participants stated firmly not being satisfied with e-learning quality and four out of five participants would like to use e-learning as a part of their further education. More male participants were satisfied with e-leaning quality than the female participants in support of some previous findings concerning higher life satisfaction in men than in women. Satisfaction with e-learning could be considered as a domain-specific satisfaction that is a part of overall life satisfaction. Keywords: gender differences in satisfaction, e-learning quality, satisfaction with e-learning.
A New Method for Abbreviation Prediction via CNN-BLSTM-CRF

It is a crucial problem to process abbreviation in the field of natural language processing. The most commonly used way to cope with this problem is to construct the reference database by predicting the abbreviation through its fully expanded form. Previous work on abbreviation prediction mostly rely on traditional machine learning algorithms, which inevitably requires a large number of manual annotations or expert knowledge to establish a feature system. In this paper, a neural network model based on CNN-BLSTM-CRF is proposed, which can predict Chinese abbreviations better without relying too much on the feature system: Firstly, convolutional neural network extracts phrase and Chinese character information from the fully expanded form, and then BLSTM-CRF deep network is constructed to annotate the fully expanded form, so as to extract its corresponding abbreviation form. The experimental results show that the method in this paper can perform better than the state-of-art method in traditional machine learning, and the results provide a reference for abbreviation research and the construction of resource repository.
Glucocorticoids and “Stress” Are Not Synonymous

Synopsis Reference to glucocorticoids as “stress hormones” has been growing in prevalence in the literature, including in comparative and environmental endocrinology. Although glucocorticoids are elevated in response to a variety of stressors in vertebrate animals, the primary functions of glucocorticoids are not responding to stressors and they are only one component of complex suite of physiological and behavioral responses to stressors. Thus, the use of the short-hand phrase “stress hormone” can be misleading. Further, simply measuring glucocorticoids is not equivalent to measuring a stress response, nor is manipulating glucocorticoids equivalent to exposing an animal to a stressor. In this commentary we highlight the problems with using functional names for hormones, and of treating cortisol or corticosterone as synonymous with stress. We provide recommendations to add clarity to the presentation of research on this topic, and to avoid conflation of glucocorticoids with stressors and the stress response in the design of experiments.
