The Relationship of Competition and Financial Commitment Revisited: A Fuzzy Set Qualitative Comparative Analysis in European Newspaper Markets     

Sam Schulhofer-Wohl  Miguel Garrido 《Journal of Media Economics》2013,26(2):60-81

The Cincinnati Post published its last edition on New Year's Eve 2007, leaving the Cincinnati Enquirer as the only daily newspaper in the market. The next year, fewer candidates ran for municipal office in the Kentucky suburbs most reliant on the Post, incumbents became more likely to win reelection, and voter turnout and campaign spending fell. These changes happened even though the Enquirer at least temporarily increased its coverage of the Post's former strongholds. Voter turnout remained depressed through 2010, nearly three years after the Post closed, but the other effects diminished with time. The authors exploited a difference-in-differences strategy and the fact that the Post's closing date was fixed 30 years in advance to rule out some noncausal explanations for their results. Although their findings are statistically imprecise, they suggest that newspapers—even underdogs such as the Post, which had a circulation of just 27,000 when it closed—can have a substantial and measurable impact on public life.  相似文献   

Resilience does not predict academic performance in gross anatomy     

Rodrigo Enrique Elizondo‐Omaña  María de los Angeles García‐Rodríguez  José Miguel Hinojosa‐Amaya  Eliud Enrique Villarreal‐Silva  Rosa Ivette Guzmán Avilan  Juan José Bazaldúa Cruz  Santos Guzmán‐López 《Anatomical sciences education》2010,3(4):168-173

Few studies have evaluated resilience in an academic environment as it relates to academic success or failure. This work sought to assess resilience in regular and remedial students of gross anatomy during the first and second semesters of medical school and to correlate this personal trait with academic performance. Two groups of students were compared: the first group included first‐year medical students in the regular course, and the second group included first‐year medical students who did not pass the regular anatomy course and so were enrolled in the remedial course. Both groups completed anonymous surveys designed to gather demographic data and establish scores on the Connor‐Davidson resilience scale, which includes 25 statements rated zero to four on a Likert scale (maximum score 100). The average resilience score was the same for both groups, 80 ± 9. The average anatomy grades differed significantly between regular students (67± 15.0) and remedial students (61 ± 12.0). While there was no overall correlation between resilience score and anatomy grade, regular students with resilience scores of 75 or greater showed slightly better academic performance than their classmates. Similarly, remedial students with resilience scores of 87 or greater faired better academically. Resilience does not predict academic performance in gross anatomy, and further work is necessary to identify those intrinsic and extrinsic factors that influence students' achievements.

Teaching skills to promote clinical reasoning in early basic science courses     

Rodrigo Enrique Elizondo‐Omaña  Jesus Alberto Morales‐Gómez  Orlando Morquecho‐Espinoza  José Miguel Hinojosa‐Amaya  Eliud Enrique Villarreal‐Silva  Maria de los Angeles García‐Rodríguez  Santos Guzmán‐López 《Anatomical sciences education》2010,3(5):267-271

Basic and superior reasoning skills are woven into the clinical reasoning process just as they are used to solve any problem. As clinical reasoning is the central competence of medical education, development of these reasoning skills should occur throughout the undergraduate medical curriculum. The authors describe here a method of teaching reasoning skills in a clinical context during a human anatomy course.

Using data mining to predict K–12 students' performance on large‐scale assessment items related to energy     

Xiufeng Liu  Miguel E. Ruiz 《科学教学研究杂志》2008,45(5):554-573

This article reports a study on using data mining to predict K–12 students' competence levels on test items related to energy. Data sources are the 1995 Third International Mathematics and Science Study (TIMSS), 1999 TIMSS‐Repeat, 2003 Trend in International Mathematics and Science Study (TIMSS), and the National Assessment of Educational Progress (NAEP). Student population performances, that is, percentages correct, are the object of prediction. Two data mining algorithms, C4.5 and M5, are used to construct a decision tree and a linear function to predict students' performance levels. A combination of factors related to content, context, and cognitive demand of items and to students' grade levels are found to predict student population performances on test items. Cognitive demands have the most significant contribution to the prediction. The decision tree and linear function agree with each other on predictions. We end the article by discussing implications of findings for future science content standard development and energy concept teaching. © 2007 Wiley Periodicals, Inc.

Physical activity among Spanish adolescents: relationship with their relatives' physical activity - the AVENA study     

Martin-Matillas M  Ortega FB  Chillon P  Perez IJ  Ruiz JR  Castillo R  Gomez-Martinez S  Moreno LA  Delgado-Fernandez M  Tercedor P;AVENA Study 《Journal of sports sciences》2011,29(4):329-336

Identifying factors related to physical activity levels in young people is important for a more efficient health promotion. The aims of this study were to assess physical activity levels in a national sample of urban Spanish adolescents, and to examine the association between significant others' physical activity (father, mother, brother, sister, and close friends) and that of the adolescents. The present study comprised 2260 adolescents (1157 boys, 1103 girls) aged 13.0-18.5 years participating in the AVENA Study. Both the adolescents' physical activity and that of their relatives and close friends was assessed by questionnaire. The odds of being active were higher in boys than girls (odds ratio?=?2.79, 95% confidence interval?=?2.34-3.33) and tended to decrease across age groups in both boys and girls. Father's and older brother's physical activity was associated with boys' physical activity, while that of any significant other was associated with girls' physical activity. When both parents reported being active, boys had nearly two times higher odds of being active and girls had nearly three times higher odds of being active. The physical activity levels of Spanish adolescents are in line with those previously reported. Physical activity levels in girls are strongly related to the physical activity of any significant other, whereas physical activity levels in boys are only related to their male relatives' physical activity.  相似文献   

Acculturative Stress and Depressive Symptomatology Among Mexican and Mexican American Students in the U.S.: Examining Associations with Cultural Incongruity and Intragroup Marginalization     

Miguel Ángel Cano  Linda G. Castillo  Yessenia Castro  Marcel A. de Dios  Angelica M. Roncancio 《International journal for the advancement of counseling》2014,36(2):136-149

This study examined associations of intragroup marginalization and cultural incongruity with acculturative stress and depressive symptoms among 155 undergraduate U.S. college students of Mexican heritage. Findings indicate that perceived interpersonal distancing by the family (intragroup marginalization) and perceived lack of cultural fit between the respondent and academic institution (cultural incongruity) had statistically significant direct and indirect effects on depressive symptoms via acculturative stress. Results also show that 39.7 % of the variance corresponding with depressive symptoms was accounted for by intragroup marginalization, cultural incongruity, acculturative stress, and other exogenous variables.  相似文献   

Student Reciprocal Peer Teaching as a Method for Active Learning: An Experience in an Electrotechnical Laboratory     

Miguel A. Muñoz-García  Guillermo P. Moreda  Natalia Hernández-Sánchez  Vanesa Valiño 《Journal of Science Education and Technology》2013,22(5):729-734

Active learning is one of the most efficient mechanisms for learning, according to the psychology of learning. When students act as teachers for other students, the communication is more fluent and knowledge is transferred easier than in a traditional classroom. This teaching method is referred to in the literature as reciprocal peer teaching. In this study, the method is applied to laboratory sessions of a higher education institution course, and the students who act as teachers are referred to as “laboratory monitors.” A particular way to select the monitors and its impact in the final marks is proposed. A total of 181 students participated in the experiment, experiences with laboratory monitors are discussed, and methods for motivating and training laboratory monitors and regular students are proposed. The types of laboratory sessions that can be led by classmates are discussed. This work is related to the changes in teaching methods in the Spanish higher education system, prompted by the Bologna Process for the construction of the European Higher Education Area  相似文献   

Thinking emotions with two-year-old children: an educational programme to improve emotional knowledge in young preschoolers / Pensando las emociones con niños de dos años: un programa educativo para mejorar el conocimiento emocional en primer ciclo de Educación Infantil     

Marta Fernández-Sánchez  Laura Quintanilla 《Cultura y Educación》2013,25(4):802-838

Abstract

This article aims to present preliminary data to validate and show the effectiveness of the educational programme Thinking emotions with a sample of children aged two years. To test its effectiveness, a sample of 57 children was selected. The sample was divided into experimental group (N = 38) and control group (N = 19). Participants were evaluated for overall development (Brunet-Lezine) and emotional understanding through two tests (AKT and TEC) before and after the implementation of the programme in the classroom. The tutors implemented the programme during school hours in weekly 45-minute sessions over six months. The results show significant advances in emotion understanding of children in the experimental group versus the control group. Results are discussed considering the implications of early education on emotions and the consequences on psychological wellbeing.  相似文献

Miguel Conchas 《Soccer & Society》2014,15(1):167-174

The FIFA (Federation Internationale de Football Association) World Cup is the world’s biggest soccer tournament and is one of the largest international sporting events. In 2014, Brazil will host the quadrennial FIFA World Cup for the second time in its history. Since this premier global mega-event involves much of the world and Brazil is a major nation that seeks to assert its position internationally, the situation is optimal for exploring various issues. Scholars have examined various aspects of the ongoing preparations. Researchers have several options worthy of exploration including, but not limited to, relevant social phenomena, the social, cultural, economic and educational impact, as well as the cultural practices related to this mega-event. The aim of this literature review is to present some key areas that should be considered in regards to the 2014 FIFA World Cup in Brazil.  相似文献
