Success in higher education

This paper analyses the determinants of success of undergraduate Nova SBE students from 2008 to 2011. We account for the question of selection that is likely to occur when we just observe the success of those students who were admitted and enrolled at school. The main result of our empirical analysis is that the high school score appears to be a stronger predictor of the students´ success than the national Math’s exam score. In addition, the evidence also suggests that male students tend to have a better performance in Economics than female students and displaced management students have more difficulties in terms of their scores. Finally, it does not seem to exist a strong visible difference on the final GPA between students from public and private schools.

Geographical distribution of Trypanosoma cruzi in triatomine vectors in the State of Mato Grosso do Sul, Brazil

Introduction This work presents the initial findings of a molecular epidemiological investigation of Trypanosoma cruzi in triatomine insects in State of Mato Grosso do Sul. Methods A total of 511 triatomines from different regions of the state were examined. Deoxyribonucleic acid (DNA) was extracted from the intestinal contents of the insects using phenol-chloroform-isoamyl alcohol (25:24:1). Polymerase chain reaction (PCR) using primers 121/122 targeting DNA kinetoplast (kDNA) was then performed to identify T. cruzi, and positive samples were subjected to PCR using the primer pair TcSC5D-F/R followed by restriction fragment length polymorphism (RFLP) with the restriction enzymes SphI and HpaI (1 U/reaction), cloning and sequencing. Results One hundred samples were positive for T. cruzi, and three discrete typing units (DTUs) were identified (TcI, TcII, and TcBat). Triatoma sordida had the highest T. cruzi occurrence (83.3%), and DTUs were found in three samples: 58.3% of the samples were TcI, 33.3% were TcII and 8.3% were TcBat. There was a clear geographical distribution of the DTUs throughout the state, with TcI, TcII and TcBat located in the center, TcI located in the east, and TcII located in the west. Conclusions This study showed the occurrence of overlapping DTUs in State of Mato Grosso do Sul. The distributions of the DTUs were different, with TcI, TcII and TcBat in the center of the state, TcI predominantly in the east, and TcII in the west. Further studies may reveal a more defined mosaic distribution of DTUs in MS.

Distúrbios osteomioarticulares : lombalgia e escoliose : prevalência e fatores associados : um estudo analítico e transversal em adolescentes da região do Algarve

RESUMO - Introdução: Os distúrbios osteomioarticulares envolvem diversas condições donde se destacam a lombalgia e a escoliose, a primeira considerando o fato que a sua prevalência tem vindo a aumentar em adolescentes consistindo num problema crescente de saúde pública que envolve custos indiretos e a escoliose pela ausência de estudos nacionais. Diversos fatores físicos, genéticos, mecânicos, comportamentais e ambientais podem estar envolvidos na patogénese das lombalgias e escolioses. O ambiente escolar, incluindo as posturas adotadas pelos alunos e o transporte das mochilas escolares, e alguns hábitos de estilos de vida constituem fatores que podem contribuir para o desenvolvimento destes distúrbios osteomioarticulares. Este estudo também aborda o estado ponderal, nomeadamente o excesso de peso e a obesidade, pois este é referido frequentemente como um potencial fator de risco destes distúrbios osteomioarticulares (apesar de ainda apresentar controvérsia na literatura), além de ser, por si só, atualmente considerado como um dos mais graves problemas de saúde pública a nível mundial. Objetivos do estudo: (1) determinar a prevalência pontual, anual e ao longo da vida de lombalgia, assim como a prevalência de escoliose em adolescentes da região do Algarve; (2) identificar os fatores associados ao desenvolvimento destes distúrbios osteomioarticulares; (3) determinar a prevalência de excesso de peso e de obesidade e explorar a sua eventual associação com a prevalência de lombalgia e escoliose em adolescentes; (4) comparar os resultados obtidos nos diferentes métodos antropométricos (Índice de massa corporal - IMC, medição das pregas cutâneas e circunferência abdominal) e verificar a sua concordância. Material e métodos: O desenho deste estudo foi de natureza observacional, analítico e transversal. O estudo foi aprovado pela Comissão de Ética da Administração Regional de Saúde do Algarve, pela Direção Regional de Educação do Algarve, pela Direção-Geral de Inovação e de Desenvolvimento Curricular, Ministério da Educação e Ciência, e pelas Direções dos Agrupamentos de Escolas que participaram do projeto. A amostra incluiu 966 adolescentes da região do Algarve, sul de Portugal, com idades compreendidas entre os 10 e 16 anos (12,24±1,53 anos), sendo 437 (45,2%) do sexo masculino e 529 (54,8%) do feminino. O método de amostragem foi aleatório estratificado, com base nos concelhos da região do Algarve, assumindo que poderia existir heterogeneidades geográficas. Os instrumentos de medida foram aplicados num único momento (2011/2012) e incluíram o Questionário de Lombalgia e Hábitos Posturais para caracterizar a presença de lombalgia e os hábitos posturais adotados pelos alunos em casa e na escola, o escoliómetro para avaliar a presença de escoliose, a balança, o estadiómetro (sendo posteriormente calculado o IMC), o adipómetro e a fita métrica. A análise dos dados incluiu técnicas de estatística descritiva, gráficas e analíticas aplicadas à todas as variáveis em estudo. Para determinar a associação entre as variáveis do estudo foi utilizada a estatística inferencial, nomeadamente o teste de independência do Qui-quadrado. Para analisar as correlações entre as medidas obtidas com os métodos antropométricos (na sua forma quantitativa), foi utilizado o coeficiente de Spearman. A influência das diversas variáveis na presença de lombalgia foi aferida através de regressões logísticas binárias, sendo os resultados apresentados como odds ratios brutos e ajustados e respetivos intervalos de confiança. Resultados: O presente estudo revelou uma elevada prevalência de lombalgia (anual: 47,2%; pontual: 15,7%; ao longo da vida: 62,1%). As raparigas apresentaram 2,05 de probabilidade de apresentar lombalgia comparativamente aos rapazes (IC 95%: 1,58-2,65; p<0,001), assim como os alunos com idades mais avançadas (13-16 anos) comparativamente aos mais novos (10-12 anos) que tiveram 1,54 de chances (IC 95%: 1,19-1,99; p=0,001). Os alunos que indicaram adotar uma postura de sentado com a coluna vertebral posicionada incorretamente apresentaram 2,49 de probabilidade de revelar lombalgia (IC 95%: 1,91-3,24; p<0,001), os alunos que afirmaram se posicionar de forma inadequada para assistir televisão ou jogar videojogos tiveram a probabilidade de 2,01 (IC 95%: 1,55- 2,61; p<0,001) e aqueles que adotaram a postura de pé incorretamente tiveram 3,39 de chance de apresentar lombalgia (IC 95%: 2,19-5,23; p<0,001). A escoliose esteve presente em 41 (4,2%) alunos. As raparigas apresentaram a maior prevalência (4,5% versus 3,9%) do que os rapazes e o mesmo foi observado nas raparigas que apresentaram a menarca tardia (8,6% versus 3,3%) e os que foram classificados como magros (7,1%), não sendo no entanto estas diferenças estatisticamente significativas. Relativamente à prevalência de excesso de peso e obesidade, os valores variaram de 31,6%, 61,4% e 41,1% de acordo com a medição do IMC, pregas cutâneas e circunferência abdominal, respetivamente. Os valores obtidos com a avaliação dos três métodos antropométricos apresentaram um elevado alto grau de correlação entre o IMC e as pregas cutâneas (p<0,001; r=0,712), entre o IMC e circunferência abdominal (p<0,001; r=0,884) e entre a circunferência abdominal e as pregas cutâneas (p<0,001; r=0,701). Conclusões: O presente estudo revelou valores de prevalência de lombalgia semelhante a estudos anteriores sendo que os alunos com idade mais avançada, ou do sexo feminino ou aqueles que adotavam a postura sentada e de pé de forma inadequada ou os que transportavam indevidamente a mochila escolar apresentaram a maior prevalência. Quanto à presença de escoliose, observou-se uma baixa prevalência não sendo verificada nenhuma associação significativa com os fatores analisados. Relativamente ao estado ponderal, verificou-se uma elevada prevalência de excesso de peso e obesidade, com a utilização dos três métodos antropométricos: IMC, medição das pregas cutâneas e circunferência abdominal, tendo sido verificado um elevado grau de correlação entre estes três métodos antropométricos. Este estudo contribuiu para determinar a magnitude destes distúrbios osteomiarticulares nesta população específica, assim como seus possíveis fatores associados. De acordo os resultados obtidos no presente estudo, torna-se necessário ações de intervenção nas escolas, envolvendo não somente os alunos, mas toda a comunidade escolar, com o objetivo de prevenção destes distúrbios osteomioarticulares através da promoção de hábitos de vida saudável.

The relationship between the education level of successor's and the firm performance in German publicly listed family firms- an empirical analysis

The purpose of this thesis is to investigate how far the education level of the second or third generation of publicly traded German family firms affects the post-succession firm performance. By conducting a correlational and regression design, the aim is to examine how several variables influence the performance of family firms. Performance measures, for example ROA and Tobin’s q and variables, like Education level and succession periods, examine analytically that a positive succession trend will occur. However, with the used model, only a less rigid model shows empirical evidence.

The impact of PBL on transferable skills development in management education

Attention to transferable skills is growing in higher education. Problem-based learning (PBL) is increasingly used in management education for its promising potential to, amongst others, promote transferable skills, including problem-solving, critical thinking and teamwork skills. However, this relationship is seldom assessed. In this study, I use structural equation modelling to examine the effectiveness of PBL, measured through students’ perceptions of satisfaction and skills development. Results show the development of transferable skills is explained by interaction with tutors and a host company, and defining teamwork rules. Satisfaction is explained by skills development, assessment issues, defining teamwork rules and understanding how organisations work. I draw conclusions and recommendations.

Sustainability education in PBL education: the case study of IEM-UMINHO

Sustainability-related skills are becoming more and more relevant for a proficient and professional engineering practice. Industrial engineers in particular, given their broad field of intervention and being at the heart of industrial activity, hold a great deal of potential and responsibility in providing and delivering best industrial practices, that support enhanced industrial systems and products. Therefore making a real contribution in generating wealth and income for all the companies’ stakeholders, including local communities, as well as adding up to more sustainable ecosystems. Previous work by the authors focused on studying the inclusion of this subject on the education of industrial engineers, especially through active-learning methodologies, as well as presenting results on the use of one such approach. The study conducted tried to identify the impacts on sustainability learning using a given specific activity, i.e. a workshop on industrial ecology, held in the 2014/2015 academic year on the Integrated MSc degree on Industrial Engineering and Management at the University of Minho, Portugal. The study uses content analysis of student teams’ reports for two consecutive academic years. The former did not include one such workshop, while the latter did. The Fink taxonomy was used in the discussion of results and reflection. The study outcomes aimed at supporting decision making on worthiness of investment on similar education instruments for sustainability competency development. Some results of the study highlight that: (1) the workshop seem to globally have a positive contribution on the sustainability learning; (2) a number of dimensions of the Life cycle design strategy wheel was developed, but the approach was not broadly used, (3) There was a mismatch on the workshop schedule; (4) students enjoy the workshop; (5) a clearer endorsement on relevance of this aspect is required. Suggestions for future work are also issued.

Pervasive business intelligence platform to improve the quality of decision process in primary and secondary education – A Portuguese case study

Business Intelligence (BI) can be seen as a method that gathers information and data from information systems in order to help companies to be more accurate in their decision-making process. Traditionally BI systems were associated with the use of Data Warehouses (DW). The prime purpose of DW is to serve as a repository that stores all the relevant information required for making the correct decision. The necessity to integrate streaming data became crucial with the need to improve the efficiency and effectiveness of the decision process. In primary and secondary education, there is a lack of BI solutions. Due to the schools reality the main purpose of this study is to provide a Pervasive BI solution able to monitoring the schools and student data anywhere and anytime in real-time as well as disseminating the information through ubiquitous devices. The first task consisted in gathering data regarding the different choices made by the student since his enrolment in a certain school year until the end of it. Thereafter a dimensional model was developed in order to be possible building a BI platform. This paper presents the dimensional model, a set of pre-defined indicators, the Pervasive Business Intelligence characteristics and the prototype designed. The main contribution of this study was to offer to the schools a tool that could help them to make accurate decisions in real-time. Data dissemination was achieved through a localized application that can be accessed anywhere and anytime.

Adult learning and education policies in Germany, Portugal and Sweden: An analysis of national reports to CONFINTEA VI

The chapter presents a theoretical proposal of three analytical models of Adult Learning and Education (ALE) policies. Some analytical categories and the corresponding dimensions are organised according to the ALE rationale which is typical of each social policy model. Historical, cultural and educational features are mentioned in connexion with the different policy models and its interpretative capacity to making sense of policies and practices implemented in Germany, Portugal and Sweden. !e analysis includes the states of the art and the official representations of ALE produced by the respective national authorities through national reports which were presented to CONFINTEA VI (2009).

The importance of the category of consciousness and education for sustainability in methodologies for eco‐efficiency in school buildings

This document reports the importance of the category of consciousness and education for sustainability in the school environment. Education in school has a potential to make the benefits of the building construction visible for society and media, showing to the students, parents and communities how sustainability in built environment could improve the people life in economic, social and environment aspects. Thus, this paper addresses the main events related to sustainability, such as the Stockholm Conference, the Brundtland report, United Nations Conference on Environment and Development (UNCED) and Agenda 21, until reaching the necessity of the elaboration of Methodologies for environmental assessment of building, and later, the development of the specific methodologies according to the buildings. It is also described some examples of sustainability in schools in Germany, Finland and Italy and what kind of sustainable systems those countries are currently using.

Does dosage in abstinence education matter?

Although past reviews uniformly criticized the efficacy and effectiveness of sexual abstinence in adolescents, new studies dispute the earlier findings. Studies that unpackage intervention programs provide one means of understanding why they succeed in some settings and not in others. This study examined 3183 students spread over 35 schools on the number of hours that they received in sexual abstinence education, in a context of health behaviors promotion. A multi-level analysis (HLM) was performed. The number of hours did not appear to make any difference in the outcome scores. Reasons for this finding are presented and their implications are provided.

Preschool education in Brazil: does public supply crowd out private enrollment?

Expanding access to preschool education is a particularly important policy issue in developing countries, where enrollment rates are generally much lower, and where private institutions constitute a much larger share of the formal preschool sector, than in developed countries. This paper examines if an expansion in the supply of public preschool crowds-out private enrollment using rich data for municipalities in Brazil from 2000 to 2006, where federal transfers to local governments change discontinuously with given population thresholds. Results from a regression-discontinuity design reveal that larger federal transfers lead to a significant expansion of local public preschool services, but show no evidence of crowding-out of private enrollment, nor of negative impacts on the quality of private providers. This finding is consistent with a theory in which households differ in willingness-to-pay for preschool services, and private suppliers optimally adjust prices in response to an expansion of lower-quality, free-of-charge public supply. In the context of the model, the absence of crowding-out effects of more public preschool providers can be rationalized by the existence of relatively large differences in willingness-to-pay for preschool services across different demand segments. Our theoretical and empirical findings therefore suggest that in developing country settings characterized by relatively high income inequality, an expansion in public preschool supply will likely significantly increase enrollment among the poorest segments of society, and need not have adverse effects on the quantity or quality of local private supply.
