    This study explores the nature of civic engagement of Muslim college students in the United States. The Community of Practice Theory is used as a conceptual structure to explore the relation between meaning, practice, identity and organization for Muslim students active in civic engagement through campus-based Muslim Student organizations. Pluralism, as shared values that combine different people and advocates wider civic participation, was adopted as part of the conceptual framework to see how the Muslim students think, serve, learn, and develop throughout the process of engagement on campus and in the local community. Particular attention is paid to the impacts of Islamophobia on the one hand and campus initiatives for diversity and inclusion on the other. The study uses a mixed method design to uncover multiple dimensions of civic engagement of the Muslim students. In the first part of the study, a close-ended survey completed by fifty Muslim students on three Midwestern college campuses with active Muslim Student Associations (MSA) explored the domains, types, and intensity of civic engagement. In the subsequent qualitative field research, interviews of 12 members of the three MSAs explored the purposes, goals, effects, values, and aims of civic engagement from personal and organizational perspectives. The qualitative design also included field observations of MSA meetings and activities. The study found that Muslim students’ engagement in civic practices is driven by religious, national, and conditional factors. Islam is the moral compass that incentivizes and guides their social and service activities on campus and in the local community. Through different aspects of practice, Muslim students affirm their presence as American citizens and encounter the negative discourses and images circulated about their faith identity. Engagement in the organization opens up ways for the Muslim students to establish constructive relations with non-Muslims, create connection and collaboration between the campus and the local community of Muslims, grow civically, and develop various leadership skills

    An Enhanced Ipv6 Anycast Routing Protocol Using Protocol Independent Multicast-Sparse Mode With Mobile Ipv6

    Get PDF
    Anycast routing is an efficient routing mechanism that enables the network to choose the nearest and most appropriate server very quickly. However, IPv6 Anycast is not used widely in practice yet, and there are many reasons for this. Firstly, IPv6 Anycast does not have its own standard protocol because anycast builds its anycast membership tree like multicast does but unlike multicast it sends only to one of the groups using unicast mechanism. The other problem is that IPv6 Anycast mechanism could not provide stateful connections between the sender and the receiver because the sender always change the receiver based on the metric or the distance. In this thesis a new IPv6 anycast routing protocol is developed to provide a stateful communication between the anycast sender and the receiver. Protocol Independent Multicast-Sparse Mode (PIM-SM) has been chosen to establish the new IPv6 anycast mechanism because of many similar properties between multicast and anycast. A new variable is proposed in the routing table called Best Metric Factor (BMF) to describe the status of the receiver (free or Busy). This factor is used to decide the appropriate receiver to choose, the advantage of the proposed design can be observed easily when there are multi-anycast senders sending their traffic to the appropriate receiver at the same time. Next we improve the mechanism by building a direct connection between the anycast sender and the anycast receiver using route optimization by mapping the objects in Mobile IPv6 to the objects in the proposed mechanism. This is because there are many similar properties between Mobile IPv6 and the proposed design. The proposed mechanism has been shown to achieve a good performance with multi-anycast senders and can provide a stateful communication between the sender and the appropriate receiver

    Ethnic differences in adipogenesis and the role of alkaline phosphatase in the control of adipogenesis in human preadipocytes and 3T3-L1 cells

    A thesis submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in fulfilment of the requirement for the degree of Doctor of Philosophy. Johannesburg, 2004Alkaline phosphatase (ALP) is a ubiquitously expressed enzyme, that has been shown to play a role in cell differentiation and organogenesis. One study has also demonstrated ALP activity in rat adipocytes. The purpose of the present study was therefore to determine whether ALP is expressed in preadipocytes and what role it may have in adipogenesis. ALP activity was detected in the murine preadipocyte cell line, 3T3-L1, and in human preadipocytes isolated from mammary tissue, and from subcutaneous abdominal fat depots. In all the cell types studied ALP activity increased in parallel with adipogenesis. In the 3T3 -L1 cell line the tissue- non -specific ALP inhibitors, levamisole and histidine inhibited ALP activity, and adipogenesis, whereas the tissue specific ALP inhibitor Phe- Gly-Gly did not inhibit ALP or adipogenesis. In human preadipocytes, histidine inhibited adipogenesis and ALP activity, whereas levamisole inhibited adipogenesis, but did not block ALP activity in intact cells. However, levamisole did inhibit ALP activity by 50% in cell extracts. Levamisole was able to inhibit adipogenesis in human preadipocytes. The tissue specific ALP inhibitor, Phe Gly Gly, did not inhibit ALP activity or adipogenesis in human preadipocytes. ALP activity and adipogenesis, were compared in preadipocytes isolated from mammary tissue taken from black (13) and white (15) female subjects. Both ALP activity and adipogenesis, were lower in white compared to black female subjects. iii Immunocytochemical, analysis of the 3T3-L1 cell line and human preadipocytes demonstrated that ALP activity was restricted to the lipid droplets of these cells. ALP activity was also measured in serum samples obtained from 100 African subjects (74 females and 26 males) of varying BMI. ALP activity was found to be higher in obese than lean subjects, whereas, the other liver enzymes or products measured in serum were not. In fact these variables correlated to varying degrees with waist-hip ratio, whereas ALP levels did not. This suggest that liver function is predominantly influenced by abdominal obesity whereas serum ALP levels are more influenced by overall body adiposity. In conclusion, ALP, may be involved in the control of adipogenesis, in the 3T3- L1 preadipocyte cell line and in human preadipocytes isolated from mammary adipose tissue and subcutaneous abdominal adipose tisssue. The presence of ALP activity in lipid droplets in 3T3-L1 cells and human preadipocytes, and the ability of ALP inhibitors to block adipogenesis strongly suggest that ALP plays a role in the control of adipogenesis.IT201

    Circular fashion: evolving practices in a changing industry

    AbstractToday we are witnessing a change in the production paradigm of the fashion industry. The negative impacts of different processes along the supply chain are evident and consumers have begun to shift to brands seeking effective organizational strategies and supply chain-management models that consider the safeguarding of the planet’s resources and demonstrate respect for people. Impelled by these developments, fashion brands are moving from market-driven to purpose-driven strategies. The fashion industry is now recognizing the circular economy (CE) as the leading entrepreneurial model for addressing supply-chain issues related to sustainability. However, there are still gaps in the levels of environmental, economic, social, and cultural sustainability being achieved. Implementation of this model on a large scale is still in the early stages and recent experience indicates a need to rethink the current linear system to enable different actors along the fashion-supply chain to adapt. Further, the fashion system lacks a holistic vision that can support and guide this sustainable transformation toward CE. This article describes how several companies are currently implementing circularity and presents evidence that an emphasis on this concept is relevant for the global fashion industry. It aims to show how emergent design practices are supporting fashion companies to better focus their sustainability agendas, to approach them in a holistic manner, and to consider all business processes with the goal of implementing sustainable development strategies. Analyzing contemporary design-driven best practices, the article introduces a taxonomy highlighting effective ongoing strategies (mini-loops) leading to incremental changes toward CE. Furthermore, it synthesizes possible future trajectories that could lead the fashion system to finally close the loop of circularity
