Using survey responses from 1300 full-time employees in the Australian Telecommunications Industry, this paper explores the relative effects of task characteristics and sub-unit structure on aspects of information processing. Results of multiple regressions revealed that task characteristics have a greater impact on amounts and timeliness of information. In contrast, structural characteristics have greater effects on the degree of openness and accuracy of information. More specifically: (a) variety and task analyzability were found to increase the amount and timeliness of information; (b) greater sub-unit size tends to reduce openness and accuracy of information, while greater participation and formalization tend to increase these. Further scrutiny of these effects revealed that (a) the impact of structural characteristics on information accuracy and openness (i.e., section-level information processing) were strongly moderated by sub-unit size and (b) the effects of task characteristics on amounts and timeliness of information (i.e., individual-level information processing) were strongly moderated by the nature of the job, as strong differences between administrative, managerial, technical, and engineering positions were discovered in this regard. 相似文献

The present study carries out an impact analysis of a conditional cash transfer (CCT) program for secondary-school girls in seven districts of Khyber Pakhtunkhwa province in Pakistan, including Battagram, Bonair, Hangu, Kohistan, Shangla, Tank, and Upper Dir. In 2012 we collected household-level primary data and used a probit model for quantitative analysis. Further, we conducted various focus group discussions and key informant interviews in the target areas. Results show that the chances of female schooling decrease with a rise in family size. The chances of female education increase by 1.8 and by 3.3 % if household heads and their spouses have one additional year of schooling, respectively. Better educational services and rises in family income increase the chances of female ecucation by 11 and 0.3 %, respectively. Finally, socioeconomic awareness, improved economic conditions, and CCTs increase the chances of female education by 5.2, 4.7, and 0.03 %, respectively. Overall, the stipend program (CCTs) shows a pareto improvement. Our results indicate that 35 % of girls will drop out in the absence of a stipend program. The present study recommends that to increase program effectiveness, local-level monitoring and program evaluation may be improved, delays in stipend payments to female students should be reduced, a grievance redressal mechanism for parents and guardians should be introduced, and clear synergies should be developed with other transfer programs. 相似文献

Blockchain plays a vital task in cybersecurity. With the exerted efforts for realising large-scale quantum computers, most current cryptographic mechanisms may be hacked. Accordingly, we need a quantum tool utilised for designing blockchain frameworks to have the ability to be executed in the level of digital computers and resist the probable attacks from both digital and quantum computers. Quantum walks may be utilised as a quantum-inspired model for designing new cryptographic algorithms. In this paper, we present a new authentication and encryption protocol based on quantum-inspired quantum walks (QIQW). The proposed protocol is utilized to build a blockchain framework for secure data transmission among IoT devices. Instead of using classical cryptographic hash functions, quantum hash functions based on QIQW are employed for linking blocks of the chain. The main advantages of the presented framework are helping IoT nodes to effectively share their data with other nodes and full control of their records. Security analysis demonstrates that our proposed protocol can defend against message attack and impersonation attacks, thus ensuring secure transmission of data among IoT devices. 相似文献

The importance of group learning has increased significantly in higher education in the past two decades (Houldsworth and Mathews, 2000). The primary focus of this study is to explore the feelings and experience of students regarding group work and group assessment in higher education. The study is exploratory based on a qualitative focus group approach. Interestingly, students felt that group work is a significant method to foster the development of critical thinking through discussion, clarification of ideas, and evaluation of others' ideas. Students consider “poor communication” and “poor attendance at group meetings” as the main challenges they face when working within a group. Also, students identified “dedicated assignment seminars” as the most effective tool, which could be used to enhance the effectiveness of group work. This study reinforces the findings of previous research into group work suggesting that the experience is a generally positive one for students. Results are discussed in the context of current theoretical and empirical work on group‐based learning, education implications and areas for further research are discussed. 相似文献

The arguments in the article are based on the ongoing discourse in the academic community and among stakeholders, which has
contributed to the articulation of the concepts and premises of sustainable development and the role of learning modalities,
technologies and networks. The article draws on this discourse to explore the economic aspects of sustainable development,
focusing on pervasive poverty, and the implications for educational actions. The concepts and underlying premises of education
for sustainable development (ESD) are discussed. The article presents the key elements of an integrated approach to fighting
poverty in the context of sustainable development. The role of learning and education in this integrated approach is outlined,
framing the educational elements within the perspective of lifelong learning. 相似文献

Even though most children in Bangladesh are enrolled in school, the country faces enormous challenges in ensuring that children
complete primary education, and learn an acceptable amount. Multiple providers—state, quasi-state, and non-state—have helped
to raise the initial enrolment rate and improve the gender balance. The critical question is how the multiplicity and diversity
of provision can contribute to achieving truly universal primary education with high completion rates and acceptable levels
of learning. A range of sub-questions relate to this critical question, including what is meant by multiple provision and
how a diversity of provisions can be shaped into a system that serves the goal of effective and equitable access. This article
addresses the above questions in the context of the history and educational development in Bangladesh. They are particularly
significant at present, as the government is about to implement a new national education policy and design a five-year national
development plan (2011–2015), which would have a decisive impact on progress towards achieving the EFA goal of universal primary
education by 2015. 相似文献

Bystanders can reveal valuable information about bullying to school personnel to take action on it. If they remain reluctant, of course, they frustrate our efforts to stop bullying. But then, why would they get involved if doing so might make them victims of aggression too?
This paper investigates the importance of adaptive shame management in encouraging bystanders to prevent bullying. Data were collected through the Cross-national School Behaviour Research Project from 1452 secondary school students (49% girls) in grades 7–10 (mean=8.42) in Bangladesh. As predicted, students who scored higher on shame acknowledgement (admitting shame, accepting responsibility, making amends) were more likely to intervene to prevent bullying. Those with low shame displacement (blaming or hitting out at others) were also likely to intervene to stop bullying. Implications of these findings pertaining to pastoral staff, counsellors and school teachers working with students to encourage coming forward against bullying are discussed. 相似文献
