This research work analyses the emotional intelligence (EI) and the social cognitive attitudes and strategies in adolescents between 12 and 17 years of age in residential care. The aim of the work is to identify those aspects that hinder their socio-emotional competence, requiring a more urgent intervention. We explore the presence of significant differences between the variables under study according to gender and age range (12–14 and 15–17) and we analyse the relationship between the dimensions of their EI and their social competence. The results show a lack of EI in these adolescents, with all three dimensions being affected: emotional attention, clarity of feelings and emotional repair. As for social competence, it can be seen that the adolescents are characterised by a lack of confidence and firmness in their interactions. Worthy of note is the impulsive cognitive style, as are the rigidity of thought and the tendency towards social mistrust and suspicion. There are many difficulties concerning the strategies for resolving social problems. This research highlights the need to design training programmes for the residential care centres that will favour their socio-emotional development.  相似文献

Over the period 1990–2010, the increase in life expectancy for males in New York City was 6.0 years greater than for males in the United States. The female relative gain was 3.9 years. Male relative gains were larger because of extremely rapid reductions in mortality from HIV/AIDS and homicide, declines that reflect effective municipal policies and programs. Declines in drug‐ and alcohol‐related deaths also played a significant role in New York City's advance, but every major cause of death contributed to its relative improvement. By 2010, New York City had a life expectancy that was 1.9 years greater than that of the US. This difference is attributable to the high representation of immigrants in New York's population. Immigrants to New York City, and to the United States, have life expectancies that are among the highest in the world. The fact that 38 percent of New York's population consists of immigrants, compared to only 14 percent in the United States, accounts for New York's exceptional standing in life expectancy in 2010. In fact, US‐born New Yorkers have a life expectancy below that of the United States itself.  相似文献

We, the Editors and Publisher of National Identities, have retracted the following book review:

Pedro García-Guirao (2019)

Book Review of The victorious counterrevolution: the nationalist effort in the Spanish Civil War. National Identities, published online on 14th February 2019, DOI:10.1080/14608944.2018.1563986

The above-mentioned book review contained some inaccuracies in quotations and some statements which may be misleading as to the contents of the book. The book review was subsequently revised and re-published as DOI: 10.1080/14608944.2018.1563986

We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.  相似文献

Survey statisticians make use of auxiliary information to improve estimates. One important example is calibration estimation, which constructs new weights that match benchmark constraints on auxiliary variables while remaining “close” to the design weights. Multiple-frame surveys are increasingly used by statistical agencies and private organizations to reduce sampling costs and/or avoid frame undercoverage errors. Several ways of combining estimates derived from such frames have been proposed elsewhere; in this paper, we extend the calibration paradigm, previously used for single-frame surveys, to calculate the total value of a variable of interest in a dual-frame survey. Calibration is a general tool that allows to include auxiliary information from two frames. It also incorporates, as a special case, certain dual-frame estimators that have been proposed previously. The theoretical properties of our class of estimators are derived and discussed, and simulation studies conducted to compare the efficiency of the procedure, using different sets of auxiliary variables. Finally, the proposed methodology is applied to real data obtained from the Barometer of Culture of Andalusia survey.  相似文献

We propose an influence diagnostic methodology for linear regression models with stochastic restrictions and errors following elliptically contoured distributions. We study how a perturbation may impact on the mixed estimation procedure of parameters in the model. Normal curvatures and slopes for assessing influence under usual schemes are derived, including perturbations of case-weight, response variable, and explanatory variable. Simulations are conducted to evaluate the performance of the proposed methodology. An example with real-world economy data is presented as an illustration.  相似文献

The establishment of the European Higher Education Area has involved specifying lists of professional competencies that programs are expected to develop, and with this the need for procedures to measure how every course within a higher education program is aligned with the program's competencies. We propose an instrument for characterizing this alignment, a process that we call assessing the relevance of a course. Using information from the course syllabus (objectives, contents and assessment scheme), our instrument produces indicators for characterizing the syllabus in terms of a competence list and for assessing its coherence. Because assessment involves quality, the results obtained can also be used to revise and improve the course syllabus. We illustrate this process with an example of a methods course from a mathematics teacher education program at a Spanish university.  相似文献

This paper details a semi-structured interview protocol that evaluators can use to develop a logic model of a program's services and outcomes. The protocol presents a series of questions, which evaluators can ask of specific program informants, that are designed to: (1) identify key informants basic background and contextual information, (2) generate logic model elements, (3) model program inputs, activities, outputs, and outcomes, (4) build a rational theory, (5) develop a program theory, (6) prioritize logic model elements, and (7) build a graphical or tabular logic model. The paper will also provide an example of how this approach was used to develop a logic model for a youth mentoring program. It is our hope and belief that with this interview protocol, novice evaluators will be able to generate comprehensive logic models like seasoned professional evaluators.  相似文献

How Satisfied are Spouses with their Leisure Time? Evidence from Europe   总被引:1,自引:1,他引:0  
This paper first identifies the determinants of spouses’ satisfaction levels within the household with respect to their leisure time and, secondly, characterizes whether their preferences have some degree of altruistic or egoistic character in regard to this particular satisfaction. To that end, it formulates a theoretical framework from the collective family model whose stochastic formulations are estimated for 14 EU countries. The general empirical results first reveal that the presence of children has a significantly negative impact on the leisure satisfaction of both spouses. Then, increases in individual incomes lead to lower own leisure satisfaction levels. Both husbands and wives show egoistic behavior with respect to the labor and non-labor incomes (wage rate) of their respective spouses’ satisfaction levels.
