Education,age and skills: An analysis using PIAAC data     

Jorge Calero  Ins P. Murillo Huertas  Josep Lluís Raymond Bara 《European Journal of Education》2019,54(1):72-92

The main aim of this article is to analyse the change of adult skills, as captured by cognitive skills assessed in PIAAC, across age cohorts, taking into account that the quality of schooling may change from one cohort to another. We estimate a model that relates numeracy and literacy skills to age, schooling, gender and variables related to both family background and labour market performance. The specification allows us to control for changes in the efficiency of the transformation of schooling into skills when drawing age‐skill profiles. Our results show that the effect of ageing on skills, once isolated from cohort effects related to schooling, decreases monotonically across consecutive cohorts. The change of the efficiency of the transformation of schooling into both numeracy and literacy skills shows a remarkably similar pattern. Nonetheless, this change differs substantially between education levels, with the efficiency of the transformation of schooling into skills showing a steadier profile for intermediate than for higher education. Finally, empirical evidence is provided for the decomposition of the differences in the skill levels of the older vs. the prime age generations. The results suggest that the progressive expansion of schooling across younger generations partially offsets the negative effect of the irrepressible ageing of society on skills.  相似文献   

Differential effects of psychological maltreatment on children of mothers exposed to intimate partner violence     

de la Vega A  de la Osa N  Ezpeleta L  Granero R  Domènech JM 《Child abuse & neglect》2011,35(7):524-531

Objective

Psychological maltreatment (PM) is the most prevalent form of child abuse, and is the core component of most of what is considered as child maltreatment. The aim of this work was to explore differential adverse outcomes of the different types of PM in the mental health and functioning of children living in homes in which they are exposed to intimate partner violence (IPV).

Method

Participants were 168 children, aged between 4 and 17, whose mothers experienced IPV. They were assessed using different measures of psychopathology and functioning: Diagnostic Interview for Children and Adolescents-IV, Child Behavior Checklists and Child and Adolescent Functioning Assessment Scale. Furthermore, IPV was assessed with the Schedule for Assessment of Intimate Partner Violence Exposure in Children and the Index of Spouse Abuse. Statistical analyses were carried out with regression models adjusted by means of Generalized Estimating Equations.

Results

Spurning was the PM subtype with the greatest global effect on the children, as it was significantly associated with internalizing and externalizing problems. Denying emotional responsiveness specifically increased the risk of internalizing psychopathology and impairment in the emotional area. Terrorizing was not significantly associated with a greater number of negative outcomes in children's psychopathology or functioning in this population.

Implications

The results suggest the importance of taking PM types into account in order to fully understand the problems of children exposed to IPV at home, and for the design of effective treatment and prevention programs.  相似文献   

Public libraries embrace citizen science: Strengths and challenges     

Anna Cigarini  Isabelle Bonhoure  Julián Vicens  Josep Perelló 《Library & information science research》2021,43(2):101090

Can public libraries become hubs for citizen science? In line with the principles of citizen science, this question was answered collaboratively with librarians from the Barcelona Network of Public Libraries who performed two hands-on activities. One activity was a training course taken by 30 librarians from 24 different libraries which enabled them to envisage citizen science implementation at each library. The other activity consisted of co-creating a citizen social science project and involved 40 library users, seven librarians from three different cities, and professional scientists. The analysis considers the perspectives of both librarians and users, through participant observation, surveys, and a focus group to identify strengths and challenges. The overall results suggest that public libraries can offer leadership in the promotion of citizen science and contribute to the mission of public libraries to act as local community hubs. The main challenges identified were related to the complexity of collaboration, uncertainty regarding research co-creation, and participant retention strategies.  相似文献   

An Approach to Find Out Students’ Motives and Influences on Their Selection of Studies and University: Results from six years of continuous institutional research in a multi‐campus system in Spain     

Josep Gallifa 《Tertiary Education and Management》2013,19(2):173-191

This paper presents an institutional research on service quality conducted to analyze the students’ motives and influences on their selection of studies and university. The research was carried out by collecting data from first‐year students in a multi‐campus system where institutions are independent in their recruitment strategies. Results from six consecutive years are presented. The meaningful coincidence with previous research, the stability of some findings along the years, and the possibilities of this approach to be useful for strategic purposes and in marketing‐related issues, make this methodology of particular interest. These results are also meaningful with a view to improving quality practices in the context of competition for the best students, and improving guidance practices to match students’ motives with higher education offer.  相似文献

Combining IRT and SEM: A Hybrid Model for Fitting Responses and Response Certainties     

Pere J. Ferrando  Cristina Anguiano-Carrasco  Josep Demestre 《Structural equation modeling》2013,20(2):208-225

This article proposes a model-based procedure, intended for personality measures, for exploiting the auxiliary information provided by the certainty with which individuals answer every item (response certainty). This information is used to (a) obtain more accurate estimates of individual trait levels, and (b) provide a more detailed assessment of the consistency with which the individual responds to the test. The basis model consists of 2 submodels: an item response theory submodel for the responses, and a linear-in-the-coefficients submodel that describes the response certainties. The latter is based on the distance-difficulty hypothesis, and is parameterized as a factor-analytic model. Procedures for (a) estimating the structural parameters, (b) assessing model–data fit, (c) estimating the individual parameters, and (d) assessing individual fit are discussed. The proposal was used in an empirical study. Model–data fit was acceptable and estimates were meaningful. Furthermore, the precision of the individual trait estimates and the assessment of the individual consistency improved noticeably.  相似文献   

Peer and self-assessment applied to oral presentations from a multidisciplinary perspective     

Joan Josep Suñol  Joan Pujol  Lidia Feliu  Rosa Maria Fraguell  Anna Planas-Lladó 《Assessment & Evaluation in Higher Education》2016,41(4):622-637

This article analyses the use of peer and self-assessment in oral presentations as complementary tools to assessment by the professor. The analysis is based on a study conducted at the University of Girona (Spain) in seven different degree subjects and fields of knowledge. We designed and implemented two instruments to measure students’ peer and self-assessment, and a rubric to guide the assessment process. Results were compared with the marks awarded by the professor. In contrast with studies by other authors, which show a high correlation between these different assessment systems, our study revealed significant deviations. Applying peer and self-assessment to oral presentation activities also demonstrates their formative value above and beyond their summative usefulness.  相似文献
