This study aims to assess the accessibility of library Web sites of top ten universities of Pakistan. The study also explores commonly identifies accessibility barriers in the subject Web sites. Accessibility analysis of library Web sites has been conducted using Web Accessibility Evaluation Tool (WAET) to examine compliance of the library Web site with Web Content Accessibility Guideline 2.0. The study also attempts to rank each Web site according to number of quality issues identified. Based on literature review, the study also proposes a framework to conduct Web accessibility evaluation of library Web sites. Web accessibility encompasses all disabilities that affect access to the Web, including visual, auditory, physical, speech, cognitive and aging (old-age).

This study examines accessibility of subject Web sites using automated accessibility evaluation tool based on Library Web site Accessibility Evaluation Framework (LWAEF). Commercial WAET SortSite® was used to assess accessibility issues in library Web sites. The tool was also tested to validate components of the LWAEF.

Result shows that 70 per cent of library Web sites do comply with World Wide Web Consortium (W3C) standards. It means that compliance to essential guidelines of priority A level of WCAG 2.0 are finely met by 70 per cent library Web sites of Pakistan. However, important accessibility issues still exist in the subject Web sites. Moreover, in terms of accessibility issues, overall quality of university library Web sites in Pakistan is in better condition.

Equal access to information by all citizens is an important UN charter supported by all developing countries. Assessing the needs of all citizens has been of great importance and value to developing countries like Pakistan, with 19.2 per cent population consisting of disabled people. The paper presents the overall status of accessibility to information and is conducted to focus the library Web sites of Pakistan for the first time. Focusing the library Web sites for accessibility evaluation, this research study will help improve accessibility elements of library Web sites in other developing countries also.

This study aims to utilize the cognitive appraisal theory of stress and coping by conducting a joint investigation of the mediating role of knowledge hiding behaviors in the relationship of exploitative leadership on employee’s work related attitudes (i.e. turnover intentions) and behaviors (e.g. job performance, creativity) and fear of negative evaluation in influencing this mediation.

Using the Preacher and Hayes’ (2004) moderated-mediation approach, the authors tested the model by collecting multi-wave and two-source data from employees and fellow peers (n = 281) working in the service sector of Pakistan.

Results of the study demonstrate that exploitative leadership adversely influences one’s performance and turnover intentions through knowledge hiding behaviors. The fear of negative evaluation moderates the indirect effects of exploitative leadership on employee’s outcomes through knowledge hiding behaviors such that these indirect effects are stronger for individuals possessing low levels of fear of negative evaluation.

The current study contributes to knowledge management and dark leadership literature by suggesting knowledge hiding behaviors as a process through which exploitative leaders unveil their negative effects on employee’s outcomes. This study is also unique in the sense, as it posits that employees might vary because of their dispositional traits (i.e. low fear of negative evaluation) in responding to exploitative leadership with greater knowledge hiding behaviors.

This study investigates despotic leadership (DL) as an antecedent to bullying behavior with a mediating role of moral emotions at work. Another aim is to study the moderating role of self-concordance to buffer the relationship between DL and arousal of moral emotions.

The authors collected two-source (self-reported and supervisor reported) time-lagged data in the shape of a three-wave survey (i.e. one month time interval for each time) from 242 dyads in the health sector of Pakistan.

The results revealed that moral emotions mediated the relationship between DL and bullying behavior. Furthermore, self-concordance moderates the relationship between DL and moral emotions, such that the relationship will be stronger in the case of low self-concordance.

Managers need to promote a culture that accommodates diversity of opinion at the organization so that everyone is able to express and share their views openly. Organizations should encourage supervisors to participate in leadership development programs aimed at eliminating DL.

This study establishes the role of self-concordance and moral emotions in the relationship between despotic leadership DL and bullying behavior.

The purpose of this paper is to develop and test a research model that investigates feedback avoidance behavior (FAB) as a mediator of the impact of leader knowledge hiding (LKH) behavior on creativity and job performance. The model also examines whether leader-follower value congruence (LFVC) moderates the aforementioned mediating linkages.

Data were collected from hotel managerial employees in two waves and their superiors in Pakistan. The hypotheses were gauged via macro PROCESS.

The findings reveal that LKH behavior intensifies employees’ FAB, which, in turn, impedes their creativity and job performance. The findings further demonstrate that the positive impact of LKH behavior on FAB is stronger among employees high on LFVC.

Management should arrange workshops that highlight the critical role of leader’s knowledge sharing with the relevant individuals. This is so important because knowledge hiding behavior heightens FAB and erodes creativity. These workshops can be followed by training programs, which focus on the importance of knowledge exchange and feedback-seeking behavior. Top managers’ and/hotel owners’ participation in these programs can be a force for mutual trust and cultivate LFVC.

The hospitality and tourism literature is devoid of evidence about the underlying process through which LKH behavior influences employee outcomes. The paper enhances current knowledge by proposing FAB as a mediator of the influence of LKH behavior on creativity and job performance. The paper is the first of its kind by assessing whether LFVC moderates the indirect influence of LKH behavior on creativity and job performance via FAB.

The purpose of this report is to outline selected presentations of the national seminar based on the theme “open access movement – initiatives, promotion and impact” organized by department of Library and Information Science, University of Kashmir held during 23‐25 October 2008 at Srinagar and narrates scenic beauty of Kashmir.

Conference report.

Many case studies and presentations were made about applications of OA software and the OA publishing model to overcome barriers and promote scholarly communication with special reference to Asia. These are included in this report.

Based on discussion during the seminar and personal interaction the author had with the participants, this report is a useful summary of open access related activities which is a topic of interest to managers of organizations, teachers and educators, librarians, open access protagonists and members of information provider communities. Some new ideas/study reports that have not been placed the traditional literature are introduced in the discussion.

The purpose of this study is to provide the full-state mathematical model and devise a nonlinear controller for a balloon-supported unmanned aerial vehicle (BUAV).

Newtonian mechanics is used to establish the nonlinear mathematical model of the proposed vehicle assembly which incorporates the dynamics of both balloon and quadrotor UAV. A controllable form of the nine degrees of freedom model is derived. Backstepping control is designed for the proposed model and simulations are performed to assess the tracking performance of the proposed control.

The results show that the proposed methodology works well for smooth trajectories in presence of wind gusts. Moreover, the final mathematical model is affine and various nonlinear control techniques can be used in the future for improved system performance.

Multi-rotor unmanned aerial vehicles (MUAVs) are equipped with controllers but are constrained by smaller flight endurance and payload carrying capability. On the contrary, lighter than air (LTA) aerial vehicles have longer flight times but have poor control performance for outdoor operations. One of the solutions to achieve better flight endurance and payload carrying capability is to augment the LTA balloon to MUAV. The novelty of this research lies in full-order mathematical modeling along with transformation to controllable form for the BUAV assembly.

The aim of this paper is to analyze the status of independence of the judiciary in Bangladesh. It is recognized worldwide that an independent judiciary is the sin qua non of democracy and good governance. However, without separation of the judiciary from other organs of the state absolute independence of judiciary is not possible. An attempt has been made in this paper to sketch the brief historical background of judicial system in Bangladesh through analyzing the meaning and basic principles of judicial independence and to what extent these principles exists in Bangladesh. How did the judiciary finally separate from the executive? After separation of the judiciary, what is the status of executive interference over judiciary in Bangladesh has also been evaluated in this paper.

The study is qualitative in nature and based on secondary sources of materials like books, journal articles, government rules, newspaper reports, etc. Relevant literature has also been collected through Internet browsing.

In this study, it has been found that from time immemorial the judicial system of Bangladesh was not completely independent from the interference of the executive branch of the government. It has also been found that from the beginning of the British colonial rule, the question of separation of the judiciary from the executive had been a continuing debate. Presently, even after separation of the judiciary, the interference of the executive over the judiciary is still continuing.

This paper opens a new window for the policy makers and concerned authorities to take necessary steps for overcoming the existing limitations of the status of judicial dependence in Bangladesh.

The paper will be of interest to legal practitioners, policy makers, members of civil society, and those in the field of judicial system in Bangladesh and some other British colonial common law countries.

The purpose of this paper is to review the library and information science literature related to the accessibility of digital resources by individuals with mental, physical or other impairments, to assess the state of research in the field and to explore new avenues for investigation.

There is an increasingly rich body of literature surrounding digital accessibility in libraries, ranging from practical guides for authors of Web content, to principles of universal design, to the ethical considerations of libraries subscribing to packages of digital content, to critical examinations of the accessibility guidelines themselves. This review is intended to be illustrative, not exhaustive; less attention is given to studies of specific tools that will become quickly outdated, and more attention is given to underlying considerations and approaches that will remain relevant even as technologies change.

Many libraries and vendors have taken steps to provide equal access to websites and electronic resources in recent years. While the literature reflects an increasing level of critical engagement with concepts around disability and diversity, it also demonstrates methodological weaknesses in assessment projects that do not lead to meaningful accessibility.

This review offers theoretical and practical perspectives from recent work that can assist librarians in planning and decision-making, as they deal with an increasingly complex landscape of digital resources.
