Educational potential of e-social work: social work training in Spain

ABSTRACT

Information and communication technologies (ICTs) have enhanced peer communication and contributed to social change and, as such, have become an essential tool in the initial training and professional development of future social work practitioners. In the new millennium, it is particularly important to provide the foundations for delivering appropriate interventions in the fields of social education, social services, healthcare and development cooperation. To face these new challenges, training programmes in the framework of the European Higher Education Area should facilitate the acquisition of skills and competencies through curricula based on ongoing assessment which promote creativity and educational innovation. Through a systematic and comprehensive review of the scientific literature, this article examines the educational potential of e-social work in Spain and the training needs of social workers from an interdisciplinary approach. A critical debate is presented throughout the paper to encourage reflection among professionals. The study highlights the importance of the acquisition of digital skills through the development of educational intervention programmes using the latest technological media and resources with a view to serving citizens in these new spaces of interaction.     

Not your lucky day: romantically and numerically special wedding date divorce risks

Characteristics of couples on or about their wedding day and characteristics of weddings have been shown to predict marital outcomes. Little is known, however, about how the dates of the weddings correlate with marriage durability. Using Dutch marriage and divorce registries from 1999 to 2013, this study compares the durations of marriages that began on unusually popular wedding dates with marriages on ordinary dates. We identify several distinct types of popular dates, including Valentine’s Day and numerically special days (dates with the same or sequential number values, e.g., 9.9.99, 1.2.03), showing that on an adjusted basis, the incidence of weddings on such dates was 137–509% higher than ordinary dates. The hazard odds of divorce for these special-date weddings were 18–36% higher than ordinary-date weddings. Sorting on couples’ observable characteristics accounts for some of the higher divorce risks, but even after controlling for these characteristics, special-date weddings were more vulnerable, with 10–17% higher divorce odds compared to ordinary dates. These relationships are even stronger for couples who have not married before.     

Women's paid work and the timing of births

It has been suggested that work-motivated women may shorten their birth intervals to allow a faster return to the workforce. This paper: (i) considers the circumstances under which such contraction would be expected; (ii) argues that British conditions in the 1940s to 1970s were favourable to the adoption of this strategy, among others; (iii) discusses some methodological issues arising in the empirical treatment of the question; and (iv) presents the results of analyses of work and maternity history information, which suggest that during the post-war period, labour-force participation was associated with both a contraction and a lengthening of birth intervals.     

On two random search problems

The paper is concerned with static search on a finite set. An unknown subset of cardinality k of the finite set is to be found by testing its subsets. We investigate two problems: in the first, the number of common elements of the tested and the unknown subset is given; in the second, only the information whether the tested and the unknown subset are disjoint or not is given. Both problems correspond to problems on false coins. If the unknown subset is taken from the family of k-element sets with uniform distribution, we determine the minimum of the lengths of the strategies that find the unknown element with small error probability. The strategies are constructed by probabilistic means.     

Some issues related to the topological aggregation of preferences

This paper deals with the topological approach to social choice theory initiated by Chichilnisky. We study several issues concerning the existence and uniqueness of Chichilnisky rules defined on preference spaces. We show that on topological vector spaces the only additive, anonymous, and unanimous aggregation n-rule is the convex mean. We study the case of infinite agents and show that an infinite Chichilnisky rule might be considered as the limit of rules for finitely many agents. Finally, we show that under some restrictions on the preference space, the existence of a Chichilnisky rule for every finite case implies the existence of a weak Chichilnisky rule for the infinite case.     

Analysis of environmental flow requirements for macroinvertebrates in a creek affected by urban drainage (Prague metropolitan area,Czech Republic)

The habitat suitability index and environmental flow requirements were assessed for ten species of macroinvertebrates in a 2 km length section of the urban Boti? creek (average flow 0.4 m³ s^?1) in Prague. Boti? creek has been affected by two combined sewer overflows (CSO). Spring, summer and fall seasonal environmental flow requirements were identified using the Physical HABitat SIMulation System (PHABSIM) approach for the whole macroinvertebrate community: Spring – optimal flow 0.32–0.38 m³ s^?1, minimal flow 0.20–0.21 m³ s^?1 and maximal acceptable flow 0.91–0.93 m³ s^?1; Summer - optimal flow 0.42–0.45 m³ s^?1, minimal flow 0.19–0.21 m³ s^?1 and maximal acceptable flow 0.95–1.00 m³ s^?1; Fall - optimal flow 0.38–0.48 m³ s^?1, minimal flow 0.22–0.23 m³ s^?1 and maximal acceptable flow 0.95–0.98 m³ s^?1. The seasonal variability of environmental flow for all three categories is approximately 10%. Environmental flow requirements of the studied species and their life stages vary with depth, velocity and bottom substratum. Due to inflow from the CSOs, the optimal and maximal acceptable flow are not maintained and the maximal flow is exceeded by more than twice its value. Although the Instream Flow Incremental Methodology (IFIM) was primarily designed for large impounded rivers, the study proved its applicability in small streams affected by urbanization and urban drainage.     

Identidad de género, ética protestante y atribución de causalidad

Resumen

El artículo analiza una doble problemática en tomo a la identidad de género: (a) los determinantes sociales de la identidad de género y (b) los sesgos preceptivos-cognitivos en la evaluación y explicación de acciones desarrolladas por un actor según su pertenencia sexual.

Se concluye que la génesis de las diferencias en las identidades sociales de hombres y mujeres esta ligada a la distribución social del trabajo en función del sexo. Igualmente se confirma la existencia de sesgos perceptivo-cognitivos en la evaluación de acciones sociales.
