Effect of B-site Dopants on Magnetic and Transport Properties of LaSrCoRuO6_6

Effect of Co, Ru and Cu substitution at B and B' sites on the magnetic and transport properties of LaSrCoRuO$_6$ have been investigated. All the doped compositions crystallize in the monoclinic structure in the space group $P2_1/n$ indicating a double perovskite structure. While the magnetization and conductivity increase in Co and Ru doped compounds, antiferromagnetism is seen to strengthen in the Cu doped samples. These results are explained on the basis of a competition between linear Co-O-Ru-O-Co and perpendicular Co-O-O-Co antiferromagnetic interactions and due to formation of Ru-O-Ru ferromagnetic networks

The political ecology of university-based social entrepreneurship ecosystems

Muurlink, OT ORCiD: 0000-0002-8251-9521Purpose: This paper aims to explore the potential agency of university-based social entrepreneurship ecosystems (U-BSEEs) from a political ecology perspective. It addresses how higher education institutions can leverage their embedded role within a community to foster social entrepreneurship, by leveraging adult learning theories of andragogy and heutagogy in (social) entrepreneurship education. Design/methodology/approach: This empirical study interviewed ten senior-level academics in the USA, the UK, Ireland and Australia with practical experience in the (social) entrepreneurship and social innovation space. Qualitative methods of structured interviews, coding and analysis were used as an appropriate procedure to examine the political ecology of U-BSEEs and the interconnectedness of its actors. Findings: Key findings included criticisms of higher educations’ role in society; financial resources and university impact on stakeholders; the potential of student-based initiatives and programs leveraging andragogy and ideally heutagogy adult learning theories; and changes universities could implement to become key actors of U-BSEEs. Student engagement and cross-disciplinary work is apparently the modus operandi to successful university based ecosystem development. Research limitations/implications: Research limitations included sample size and lack of junior and mid-level academic perspectives; surveys could be conducted in future research on the topic to generate quantitative data to strengthen findings. Implications of the research suggest that universities possess the necessary resources and personnel to serve as keystone actors of an ecosystem, but currently do not leverage the expertise available to them. Practical implications: All respondents concurred that focusing on students as change agents, and building social entrepreneurship education programs could foster a trophic cascade of increased collaboration, economic growth, political capital and social good in the local and regional ecosystem. Originality/value: This study is original in its attempt to build on the entrepreneurship ecosystem literature by considering the agency of U-BSEEs from a political ecology lens. © 2018, Emerald Publishing Limited

An Integrative Theory Addressing Cyberharassment in the Light of Technology-Based Opportunism

Scholars are increasingly calling for a deeper understanding of cyberharassment (CH) with the goal of devising policies, procedures, and technologies to mitigate it. Accordingly, we conducted CH research that (1) integrated social learning theory (SLT) and self-control theory (SCT); (2) empirically studied this model with two contrasting samples, experienced cyberharassers and less experienced cyberharassers; and (3) conducted post hoc tests to tease out the differences between the two samples. We show that for less experienced cyberharassers, CH is largely a social-psychological-technological phenomenon; whereas, for experienced cyberharassers, CH is primarily a psychological-technological phenomenon. Our study makes a threefold contribution: (1) it shows the value of integrating two theories in a holistic and parsimonious manner to explain CH; (2) it shows that SCT alone is a more relevant framework for experienced cyberharassers, whereas a combination of SCT and SLT better explains less experienced cyberharassers; and (3) it reveals that the role of technology in fostering CH is crucial, regardless of the sample. The differential, yet consistent, findings demonstrate that addressing CH is contingent upon not only identifying theoretical approaches but also identifying the particular samples to which these theoretical approaches will be more suitable. Of several implications for practice, the most important may be that anonymity, asynchronicity, and lack of monitoring are the technology choices that foster CH, and thus these should be mitigated in designing social media and other communication technologies
