Participation ahead: perceptions of Masters degree students on reciprocal peer learning activities

Peer Learning is broadly described as the development of knowledge or skills by individuals from similar statutory conditions who are learning from and with each other in both formal and informal ways. There is a considerable amount of published work on peer learning in the context of schools and undergraduate courses but little work has been developed around postgraduate levels, specifically with Masters courses. The goal of the research presented in this paper was to understand how Masters degree students perceive and engage with a peer learning activity set in a taught module. One specialist subject topic from the curriculum was assigned to each student who, during two sessions in regular teaching times, had to perform both as peer tutor and tutee in a reciprocal peer learning approach. Two questionnaires were applied - one for each role the students had to perform. Results reveal that the majority of students considered the peer tutor role undeniably positive; however, while performing as tutees, students expressed skepticism regarding the effectiveness of the approach. As the credibility of peers was evidenced as an issue (when set against these students’ high expectations), this paper contends that reciprocal peer learning may not be the most suitable peer learning method for master levels

It’s Milestone, not Limescale! Milestoned group supervision as an approach to descale postgraduate projects

Postgraduate students often face the constraints of overlapping non-academic duties, for which the timely completion of their degree can become a challenging commitment. Collective supervision grounded in milestones and shareable deliverables can help in providing them with a sense of progression whilst developing confidence in their own work

In Search of Lost Latin-American Colours: an Analysis of the Constitutional Protection of LGBTI Rights in Latin America

This study investigates the constitutional protection of LGBTI rights in South America and Mexico. Under the theoretical framework of Nancy Fraser’s postwestphalian democratic justice, it questions whether the constitutional protection of these rights in such countries is satisfactory in order to move forward towards the accomplishment of justice to LGBTI persons. The research conducts an empirical study and undertakes a qualitative analysis using the techniques of literature review, documental analysis, and survey. Among the results, it was determined that only two of the analysed constitutions expressly prohibits both sexual orientation – and gender identity-based discrimination. Only one of them uses gender-neutral language in the provision regarding civil union and, therefore, enables the union between two people of the same gender. Under another perspective, the answers of the majority of the Latin-American organizations in the survey indicated that the constitutional protection of LGBTI rights is unsatisfactory in their countries. Therefore, after the analysis of all the data obtained in the research, it was possible to conclude that the constitutional protection is precarious and does not guarantee the most basic rights to LGBTI population

Cause and Effect of Threshold-Voltage Instability on the Reliability of Silicon-Carbide MOSFETs

A significant instability of the threshold voltage (VT) in silicon carbide (SiC) MOSFETs in response to gate-bias and ON-state current stressing was discovered and examined as a function of bias, temperature, and time. It was determined that the likely mechanism causing this effect is the charging and discharging of gate-oxide traps, located close to the interface of the SiC conducting channel, via a direct tunneling mechanism. High-temperature reverse-bias induced leakage current in the OFF-state was identified as a potential failure mode. A simultaneous two-way tunneling model was developed, based on an existing one-way tunneling model, to simulate the time-dependent and field-dependent charging and discharging of the near-interfacial oxide traps in response to an applied gate-bias stress. The simulations successfully matched experimental results, both with respect to measurement time and to bias-stress time as a function of gate bias. Experimental results were presented, showing that the VT instability increases with both increasing gate-bias-stress time and bias-stress magnitude. The measurement conditions, including gate-ramp speed and direction, were shown to have a significant influence on the measured result, with a 20-μs measurement revealing instabilities three times greater than those at standard 1-s measurement speeds, whereas 1-ks measurements showed shifts only half as large. High-temperature bias stressing was found to cause even more significant increases in the VT instability. ON-state current stressing was found to also increase the VT instability, due to self-heating effects. VT shifts as large as 2 V were reported, with the number of calculated oxide traps switching charge state varying between 1×1011 and 8×1011 cm–2, depending on processing, stress, and measurement conditions. The standard post-oxidation NO anneal was shown to reduce the number of active oxide traps by about 70 percent. The dominant oxide trap was identified as an E-prime-center type defect—a weak Si-Si bond due to an oxygen vacancy which has been broken during processing or subsequent device stressing. The large increase in bias-stress induced VT instability at temperatures above 100 °C was explained by an increase in the number of active E-prime-center type defects. Existing reliability qualification standards based on silicon device technology are inadequate for SiC MOSFETs and need to be revised, with particular attention paid to the measurement conditions
