Overeducation on the Belgian labour market: evaluation and analysis of the explanatory factors through two types of approaches

This paper examines the incidence and determinants of overeducation in the Belgian private sector. Two different approaches are used to define overeducation by means of data on characteristics of employees and employers. Using the 1995 Structure of Earnings Survey, between 22% and 24% of the workforce is found to be overeducated. Results support the idea that employers view labour market experience as a substitute for formal education. They also show that male workers and people employed in state‐owned firms are less affected by overeducation. Further results suggest that the size of the establishment has a very weak (negative) impact on overeducation.     

On the influence of the architecture of poly(ethylene glycol)-based thermoresponsive polymers on cell adhesion

Thermoresponsive polymer surface coatings are a promising tool for cell culture applications. They allow for a mild way of cell detachment that preserves the activity of membrane proteins—a prerequisite for reliable cell analysis. To enlarge the application range of these coatings to cells with different adhesion properties, we synthesized various novel poly(ethylene glycol)-based thermoresponsive polymers and describe how (i) their chemical structure and (ii) their surface density affect their efficiency. In order to quantify the influence of both factors, the time for cell spreading and rounding efficiency were observed. As a result, efficiency of cell rounding, which is closely correlated to cell detachment, is less affected by both factors than the time needed for cell spreading. This time can effectively be adjusted by the molecular architecture which includes the length of the polymer backbone and the side chains. Based on this work, recommendations are given for future optimization of functionality of thermoresponsive polymer coatings for cell culture applications.     

Approaches to studying in higher education Portuguese students: a Portuguese version of the approaches and study skills inventory for students

This paper examines the validity of the Approaches and Study Skills Inventory for Students—short version (ASSIST; Tait et al. in Improving student learning: Improving students as learners, 1998), to be used with Portuguese undergraduate students. The ASSIST was administrated to 566 students, in order to analyse a Portuguese version of this inventory. Exploratory factor analysis (principal axis factor analysis followed by direct oblimin rotation) reproduced the three main factors that correspond to the original dimensions of the inventory (deep, surface apathetic and strategic approaches to learning). The results are consistent with the background theory on approaches to learning. Additionally, the reliability analysis revealed acceptable internal consistency indexes for the main scales and subscales. This inventory might represent a valuable research tool for the assessment of approaches to learning among Portuguese higher education students.     

An analysis of the effects of in‐service teacher training on Turkish preschool teachers’ attitudes towards inclusion

Any implementation of an inclusive policy is largely dependent on educators’ attitudes. In Turkey, many teachers who educate preschool children with Special Educational Needs (SEN), and who have not received in‐service teacher training (INSET) are observed to have negative attitudes towards their SEN students. The aim of this article is to examine differences between the attitudes of preschool teachers before and after an INSET course. Sixty‐six preschool teachers were selected for this study which had a single group pre–post‐test design. The teachers’ opinions and attitudes relating to mainstreaming SEN students in regular educational environments were assessed using the ‘Opinions Relative to Mainstreaming’ scale. The data indicate that these teachers were affected by the INSET programme in such a way that their attitudes towards the inclusion of SEN students became more positive.     

Acute effects of aerobic exercise performed with different volumes on strength performance and neuromuscular parameters

The aim of the present study was to investigate the acute effect of the aerobic exercise volume on maximum strength and strength-endurance performance; and possible causes of strength decrements (i.e. central and peripheral fatigue). Twenty-one moderately trained men were submitted to a maximal incremental test to determine anaerobic threshold (AnT) and maximum dynamic strength (1RM) and strength-endurance (i.e. total volume load [TV]) tests to determine their baseline strength performance. Following, subjects performed six experimental sessions: aerobic exercise sessions (continuous running at 90% AnT) with different volumes (3?km, 5?km or 7?km) followed by 1RM or strength-endurance test in the 45° leg press exercise. Maximum voluntary isometric contraction (MVIC), voluntary activation (VA) level, contractile properties, and electromyographic activity (root mean square [RMS]) of the knee extensor muscles were assessed before and after aerobic exercises and after strength tests. TV was lower after 5?km and 7?km runs than in the control condition (12% and 22%, respectively). Additionally, TV was lower after 7?km than 3?km (14%) and 5?km (12%) runs. MVIC, VA, RMS, and contractile properties were reduced after all aerobic exercise volumes (～8%, ～5%, ～11% and ～6–14%, respectively). Additionally, MVIC, VA, and contractile properties were lower after strength tests (～15%, ～6%, ～9–26%, respectively). In conclusion, strength-endurance performance is impaired when performed after aerobic exercise and the magnitude of this interference is dependent on the aerobic exercise volume; and peripheral and central fatigue indices could not explain the different TV observed.
