Search systems and their features: What college students use to find and save information

College students have often been surveyed about their general information seeking behaviors. However, little has been done to explore what specific system features they use to find and save information when they are working on their real-life tasks. In this study, 32 college students were invited to an information interaction lab for a session in which they recalled a recently finished task and worked on a to-be-finished task using a computer in the lab. They were asked to complete questionnaires regarding what systems they used to finish their tasks and what features were helpful for searching and for saving information. Results showed that college students rely more heavily on the Internet sources than on library sources, even for their course related work. The study identified fourteen categories of system features helpful for information search and eight categories helpful for information saving. The findings have implications for designing systems that will better help people accomplish their tasks.     

A data-mining approach to biomarker identification from protein profiles using discrete stationary wavelet transform

Objective: To develop a new bioinformatic tool based on a data-mining approach for extraction of the most infor-mative proteins that could be used to fred the potential biomarkers for the detection of cancer. Methods: Two independent datasets from serum samples of 253 ovarian cancer and 167 breast cancer patients were used. The samples were examined by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). The datasets were used to extract the informative proteins using a data-mining method in the discrete stationary wavelet transform domain. As a dimensionality re-duction procedure, the hard threshoiding method was applied to reduce the number of wavelet coefficients. Also, a distance measure was used to select the most discriminative coefficients. To find the potential biomarkers using the selected wavelet coefficients, we applied the inverse discrete stationary wavelet transform combined with a two-sided t-test. Results: From the ovarian cancer dataset, a set of five proteins were detected as potential biomarkers that could be used to identify the cancer patients from the healthy cases with accuracy, sensitivity, and specificity of 100%. Also, from the breast cancer dataset, a set of eight proteins were found as the potential biomarkers that could separate the healthy cases from the cancer patients with accuracy of 98.26%, sensitivity of 100%, and specificity of 95.6%. Conclusion: The results have shown that the new bioinformatic tool can be used in combination with the high-throughput proteomic data such as SELDI-TOF MS to find the potential biomarkers with high discriminative power.     

Implication de l'analyse de productions d'élèves dans la formation des maîtres du primaire

Several studies have shown that pre-service teachers enter their pre-service training with already formed conceptions pertaining to teaching and learning. Pre-service teachers are considered as epistemologically complex beings with varying postures they adopt according to differing contexts. This article looks at the meanings pre-service teachers attribute to pupil errors and how these meanings evolved over the course of a 15 week course in mathematics education. Pre-service teachers were interviewed at two intervals during their first semester: at mid session and at the end. First, we identified the various kinds of analyses they brought to bear upon pupil errors as well as the interventions they suggested to rectify these errors. Then, we conducted a statistical analysis of the changes in the type of interventions suggested. Four trend indicators were created to help understand these changes. When analysing pupil's errors, pre-service teachers identified specific conceptual elements without situating them within a global context. This led to piecemeal interventions about how pupils ought to correct their errors. In conclusion, pre-service teachers' appear to base their analyses of pupils's errors upon an epistemological positioning ween title ‘former-pupil stance‘. This stance seems to create a resistance to changing their conceptions regarding the teaching and learning of mathematics.

The effect of content representation design principles on users’ intuitive beliefs and use of e-learning systems

A model is proposed to assess the effect of different content representation design principles on learners’ intuitive beliefs about using e-learning. We hypothesized that the impact of the representation of course contents is mediated by the design principles of alignment, quantity, clarity, simplicity, and affordance, which influence the learner’s intuitive beliefs about using e-learning systems. The model was empirically validated using data collected from a survey administered to university students. This study demonstrates that these design principles are essential predictors of learners’ intuitive beliefs, which in turn directly influence their decisions about using e-learning systems. The findings provide system designers with quasi-quantitative managerial insights into how to motivate users to continue using e-learning systems.     

The alignment between the fourth grade Lebanese science curriculum and classroom assessments

The purpose of this study was to investigate the alignment between the fourth-grade summative classroom assessments and the ‘Matter and Energy’ unit in the Lebanese science curriculum using: content and cognitive levels. Summative assessments were collected from a sample of 17 schools. The alignment between the classroom assessments and the Lebanese science curriculum were examined using three instruments: Curriculum Coding Sheet, Items Coding Sheet, and Item Analysis Sheet. The curricular learning objectives were used for matching the test items to the learning objectives in terms of content. Findings showed moderate content alignment; further analysis revealed that public schools had higher content alignment, and they covered a wider range of topics. In terms of cognitive level, there was a low alignment between the assessments collected and the curriculum; however, there were items that had higher cognitive level. Recommendations for curriculum developers and future research are discussed in light of these findings.     

Convergence Between Platforms in the Newsroom

Through ethnographic observation and content analysis, this study aims to classify the Al-Jazeera Mubasher (AJM) newsroom according to the Schantin model of newsrooms, describe the network’s convergence level based on the Dailey, Demo, and Spillman Dynamic Scale Model, and present a unique model elucidating how, specifically, convergence works at AJM. Based on the Schantin model of newsrooms, AJM can be classified as a second-generation newsroom, a “cross-media platforms newsroom.” Convergence among the different platforms of AJM is considerable, but still below full convergence level. Accordingly, the AJM newsroom can be classified into the fourth level of the Dailey et al. Dynamic Scale Model — “content sharing.” The unique AJM-specific model presented near the end of this paper depicts the ways in which different AJM platforms function and interact inside the newsroom, explains the degree of convergence between platforms, and classifies the newsroom in terms of its convergence level.     

Perceptions of police-civilian encounters: Intergroup and communication dimensions in the United Arab Emirates and the USA

This study investigates the impact of perceived police accommodation on police–civilian interactions. Elaborating theoretically beyond a range of cross-cultural studies, we examine the cultural impact of accommodative communication in the United Arab Emirates and the USA, as the prior context demonstrates sociocultural parallels and differences including the influence of Sharia law. Between-country comparisons evaluate the mediating role of trust, affect, and intergroup orientation on various civic outcomes. Accommodative communication was the strongest predictor of trust for both nations and demonstrated a direct impact on moral alignment and willingness to help only in the United Arab Emirates.     

Relationships Differentiation: Cross-ethnic Comparisons in the Malaysian Workplace

This research examines how Malaysian managers and employees interpret and embody leader–member relationships differentiation. To analyze this question, we conducted a thematic analysis of top management, middle management and supporting dialogue group discussions. Results showed that leader–member relationships differentiation is a symbol that is essential for the creation and sustenance of leader’s conceptual skills, communication openness, respect, trust, and age differentiation. These findings validate our proposition of leader–member relationships differentiation in Malaysian workplace and empirical support for the central roles of communication exchange processes in workgroups.     

Testing a Model of Intercultural Willingness to Communicate based on Ethnocentrism,Ambiguity Tolerance and Sensation Seeking: The Role of Learning English in Iran

The present study aimed at testing a model of intercultural willingness to communicate based on ethnocentrism, ambiguity tolerance and sensation seeking between English and non-English major university students in Iran. A significant difference was found between the two groups on ethnocentrism and the results showed that the model fit the data adequately. Ethnocentrism was the strongest predictor of intercultural willingness to communicate for both groups. Sensation seeking was a significant predictor of intercultural willingness to communicate only for the non-English major university students. Moreover, sensation seeking and ambiguity tolerance were significant predictors of ethnocentrism.     

From mousedeer to mouse: Malaysian animation at the crossroads

Abstract

Long‐form animation began commercially in 1995 on a Government initiative. Since then, there has been an unprecedented production of animation for television and cinema, far surpassing several ASEAN countries that have studios providing animation services for foreign countries but do not have their own, homegrown series or features. However, Malaysian animation is at the crossroads. Even though foreign sales have been made, it is not cost‐effective for producers to continue making animation. The delay in approving contracts by the Government station (the only TV station that pays US$10,000 per episode), has caused some producers to fold up or downsize. The problem is further compounded with the large number of graduates entering the industry – with too few studios willing, or able, to employ them. More and more foreign TV series are flooding the TV channels. Action needs to be taken to prevent the animation industry from floundering. This paper will explore the state of the industry to see what needs to be done so that Malaysia will not lose out in the production of animation films and TV series featuring local stories and characters that can effectively reach out to young people and, at the same time, can appeal to a global audience.
