To practice or not to practice? Designing higher education curriculum to boost employability

One important dimension of Higher education curriculum design pertains to the inclusion of internships in study programmes. These have been generally conceptualized as learning experiences capable of bridging theoretical knowledge and hands-on experiences. The underlying pedagogical relevance is based on the premise that internships create the possibility of contextualized learning, fostering both professional growth and students’ self-esteem and pro-activity (Little, 2006). Interns are provided with the opportunity of early networking, as they enrol in practical activities and professionally interact with other people, besides their academic teachers and their graduate colleagues (Alpert, Heaney, & Kuhn, 2009; Weible, 2009). Research concerning internships has extensively reported the overwhelming positive effect of internships. Nevertheless, a more recent trend in literature has argued that little has been said concerning the relationship between internships and graduate employment or employability. Wilton (2012), for example, argues that more needs to be understood about the characteristics and specificities of internships and the extent to which such characteristics are capable of overcoming the current concern over the increase of graduates’ unemployment rates. Research conducted on the Portuguese case based on a database of 1,168 study programmes of first cycle degrees sough to redress this gap. Besides demonstrating that study programmes which include internships (cooperative education) tend to generate lower levels of unemployment than those that do not include internships, this research has suggested that the nature and structure of internships significantly impacts on graduate unemployment rates. In specific, mandatory internships tend to outperform their optional counterpart in reducing graduate unemployment levels. Moreover, thin sandwich courses also seem to be more beneficial than thick sandwich courses, suggesting that expanding and diversifying internships throughout the curriculum can reduce graduate unemployment rates. These results strongly suggest that it is not (only) the internship learning experience per se that makes the difference considering graduate employability, but (also) the way those internship experiences are organized along the study programme. This poster is, thus, focused on the nature and structure of internships, assessing their implications for higher education curriculum design. It does so by exploring the perspectives of the main stakeholders involved in internships regarding their motivations; required efforts; and expected outcomes. Empirically, the poster is based on the content analysis of semi-structured individual interviews to units coordinators and also focus groups conducted with coordinators of study programmes; internship supervisors (both academics and employers); and also interns. Qualitative analysis has been sustained by the main learning models traditionally used in research on work-based learning and aims at identifying a set of principles related with internships design, and modes of embedding them along an entire course, which may contribute to the development of graduates’ employability. Reported findings may constitute an important primer for reflection on the design of pedagogical strategies that maximize the contextual learning outputs of internships in a more systematic way, being particularly relevant for leading academics, namely those involved in curriculum design

Resistance Spot Welding of Dissimilar Steels: Temperature Curves

Resistance spot welding was used to joint AISI 316L austenitic stainless steel and AISI 1020 low carbon steel. During the welding process, temperature measurements were taken to obtain the temperature curves. Because of the different chemical compositions of the carbon steel and stainless steels, their thermal conductivity values are also different. Electrical resistivity is also an important parameter when carbon steel is spot welded to stainless steel. Differences in the thermal conductivity and in the electrical resistivity of metals lead to an asymmetrical weld nugget in the dissimilar joints. Dissimilar resistance spot welding can be more complex than similar welding due to different thermal cycle experienced with each metal

Testando as previsões de trade-off e pecking order sobre dividendos e dívida no Brasil

This article shows that the Brazilian companies have a low target payout ratio, although the local tax code favors dividends' distributions. The dividends paid present fast adjustment to current earnings, but part of the short-term variation in earnings is still absorbed by debt. Confirming predictions shared by the trade-off and pecking order models, more profitable firms and less levered firms have higher dividend payouts. Consistent with the pecking order model, dividends do not vary in the short-term to accommodate investments. Finally, more profitable firms and firms with fewer investments are less levered, accepting the pecking order hypothesis against the trade-off one.Este trabalho mostra que as companhias brasileiras distribuem uma proporção pequena dos lucros em dividendos apesar da legislação favorável. Os dividendos pagos são rapidamente ajustados ao lucro corrente, mas parte da variação de curto prazo nos lucros é absorvida por dívida. De acordo com a previsão comum dos modelos de trade-off e pecking order, as firmas mais lucrativas e menos endividadas distribuem uma maior proporção. Ainda de acordo com a pecking order, os dividendos não sofrem variações de curto prazo para acomodar os investimentos. Finalmente, as firmas mais lucrativas e que menos investem são as menos endividadas, favorecendo a pecking order contra trade-off
