An Explanatory Model of Dating Violence Risk Factors in Spanish Adolescents

Dating violence is a serious public health issue that needs further understanding in terms of risk factors that may be involved in it. The main goal of this study was to test a mediational model of dating violence risk factors. The sample was composed of 477 secondary and college students from Spain (59% females). A dynamic developmental explanatory model considering aggressiveness, insecure attachment, interparental conflict, and peer dating violence was tested using a multigroup structural equation model. Aggressiveness partially mediated the relation between anxious attachment and dating violence and fully mediated the association between interparental conflict resolution and dating violence. Furthermore, perceived peer dating violence was a direct predictor of dating violence. Implications for prevention and intervention plans are discussed.     

Evaluation of a personal safety program with Latino preschoolers

This study evaluated a personal safety educational program designed for Latino families attending preschools in a large metropolis. Seventy-eight children who participated in the Kids Learning About Safety program were compared to 45 control children. Compared with controls, participating children demonstrated enhanced ability to recognize inappropriate touches, learned correct genital terminology, were able to recognize the inappropriateness of touch requests made by "good" people, demonstrated higher levels of personal safety skills, and learned general safety rules. Gains in knowledge were maintained at three-month follow-up testing for all content areas except genital terminology. Although feedback provided by participating families was positive, recruiting participants and maintaining attendance at sessions was difficult. Discussion includes recommendations for future research and engagement of this population.     

Urban impacts on tropical island streams: Some key aspects influencing ecosystem response

Improving our understanding of the impacts of urbanization on tropical island streams is critical as urbanization becomes a dominant feature in tropical areas. Although the ??urban stream syndrome?? has been successful in summarizing urban impacts on streams, the response of some island streams is different to that expected. Here we review available information on urban impacts to tropical island streams and describe unique responses to urbanization. We identified three key aspects that play particularly important or unique roles in determining tropical-island stream integrity: biotic response to water pollution, movement barriers along the stream network, and altered geomorphology that results in habitat loss. As expected, water pollution negatively impacts stream ecosystems in tropical islands and in some regions impacts can be severe, as untreated wastewaters are directly discharged into streams. While aquatic insects show the expected responses to pollution, other native fauna (e.g., shrimps and fishes) appear to be less impacted by moderate levels of pollution. Movement barriers along the stream network are especially important as much of the tropical island fauna have diadromous (either amphidromous or catadromous) life histories. Most native freshwater mollusks, shrimps, and fishes inhabiting tropical islands are diadromous and depend on unimpeded connections between freshwater and marine environments to complete their life cycles. The presence of these species in urban streams is best explained by longitudinal connectivity rather than by the degree of urban impact. Finally, in streams that remain connected to marine environments, the presence of native shrimps and fishes is strongly related to the physical habitat. Fish assemblages in channelized and severely altered stream reaches are almost completely devoid of native fauna and tend to be dominated by non-native species. In contrast, relatively diverse shrimp and fish assemblages can be found in reaches that retain their physical habitat complexity, even when they are impacted by urbanization. Our understanding of urban impacts on tropical island streams remains limited. However, the identification of key aspects can help us better understand urban impacts on streams in tropical islands, and best focus our management and research efforts to protect these unique ecosystems.     

Nonlinear models of disability and age applied to census data

It is usually considered that the proportion of handicapped people grows with age. Namely, the older the man/woman, the more the level of disability he/she suffers. However, empirical evidence shows that this assessment is not always true, or at least, it is not true in the Spanish population. The study tries to assess the impact of age on disability in Spain. Each gender has been treated separately because it can be shown that men and women have their own pattern of behaviour. Three different methods of estimation have been used to check the link between those variables. The results seem to support the idea that the relationship among age and the intensity of disability is not always direct. One of the concluding remarks in this analysis is that the method of estimation has a great incidence in the final results, especially in central ages between 20 and 80 years old.     

Extreme value and cluster analysis of European daily temperature series

Time series of daily mean temperature obtained from the European Climate Assessment data set is analyzed with respect to their extremal properties. A time-series clustering approach which combines Bayesian methodology, extreme value theory and classification techniques is adopted for the analysis of the regional variability of temperature extremes. The daily mean temperature records are clustered on the basis of their corresponding predictive distributions for 25-, 50- and 100-year return values. The results of the cluster analysis show a clear distinction between the highest altitude stations, for which the return values are lowest, and the remaining stations. Furthermore, a clear distinction is also found between the northernmost stations in Scandinavia and the stations in central and southern Europe. This spatial structure of the return period distributions for 25-, 50- and 100-years seems to be consistent with projected changes in the variability of temperature extremes over Europe pointing to a different behavior in central Europe than in northern Europe and the Mediterranean area, possibly related to the effect of soil moisture and land-atmosphere coupling.     

Who am I when I don't know who I am? The problem of personal identity in infants and elderly with cognitive disabilities

This article addresses the problem of whether we can speak of personal identity in cases of infants or elderly with cognitive disabilities as hydrocephaly or dementia, lives that could be considered borderline in terms of personal identity because they lack certain characteristics normally considered indispensable for personal life. Taking as a reference recent discussions on personal identity, particularly the narrative theories of Hilde Lindemann, Françoise Baylis and Marya Schechtman, the article analyses in what sense, under what assumptions, and in what way such a thing could be defended. Finally, some problems and objections to these approaches are considered.     

From a Given to a Construct

The transition towards a cognitive and post-industrial economy has led to the emergence of new strategies of capture of the immanent productive capacities of the social forces. Heritage entities are subject to, and also participate in, processes by which common creativity and knowledge are being harnessed by novel forms of rent and control. The objective of this paper was to show that conceiving heritage as a common situated in specific contexts rather than as a universal essence can open up novel epistemological spheres of communication between different knowledge practices. Also, it can help bridge some ontological gaps among the various stakeholders in the arena of heritage, such as academics, managers, architects, local communities and market forces. This entails considering heritage as an emergent material and immaterial construction process involving many different agents. Currently, these processes tend towards the privatization of common values and the shattering of local communities. Normally, this situation entails a fundamental alienation between objects and subjects, and the reification of heritage. This paper suggests that considering heritage as a common could provide a different perspective to tackle this crucial problem. Accordingly, scholars should not only be bound to a critical discursive stance, but should also commit to ‘ontological politics’ that would situate them as mediators between the global hierarchies of value generated by heritage and the common productive potential of local communities.     

La investigación-acción en la frontera del siglo XXI

Resumen

Se realizaron dos investigaciones empíricas siguiendo una estrategia de observación pasiva con modelos causales; sobre dos muestras de 339 y 95 sujetos, respectivamente. El objetivo de las mismas es poner a prueba la hipótesis de la relación negativa entre privacidad y comunidad; así como estudiar la incidencia de algunas características psicológicas, sociales y ambientales sobre ambos conceptos. Los resultados ratifican la esperada relación negativa entre privacidad y comunidad. Se confirma la importancia del impacto sobre dichos fenómenos de las variables consideradas como determinantes, pero sorprende el efecto contrario al esperado de las variables relacionadas con la densidad de población, que fue inverso al que proponía nuestro modelo.
