ABSTRACT The relationship between social work and Information and Communication Technologies (ICTs) is an awkward one in Spanish tradition, particularly from social work perspective due to a certain lack of institutional and professional competence in terms of understanding the capabilities of ICTs. Young people use ICTs to connect to each other and express themselves, however. ICTs represent a means—increasingly the main one—for young people to build and communicate their own identities and understand reality. As with other social sciences, social work suffers from a difficult relationship with young people. Youth is often studied differently and sometimes perceived as a problem that ends when adulthood is reached. In this context, the relationship among ICTs, social work and young people is also a difficult one. But this problem may also be a solution. By adopting a critical ICT approach, social work can create innovative initiatives and frameworks to improve communication between social work practitioners and teachers as with young people and students. Imagination and empathy will clearly be key to achieving this, in addition to deeper involvement in the use of new software and applications that can offer enhanced communication and build bridges between social workers and young people. 相似文献

AbstractThe aim of this paper is to examine the relationship between transformational leadership and work satisfaction, as well as to analyse the mediating role of group identification and work engagement in a police training process at a Chilean professional military institution. The sample was made up of 985 candidates representing all the candidates that joined the units of the country in the different locations. Officers and non-commissioned officers acting as instructors were considered ‘leaders’, while their ‘followers’ were the young candidates in the training period. It was found that all the relevant variables were positively and significantly interrelated, and a model of structural equations revealed that both work engagement and group identification played a mediating role in the relationship between transformational leadership and work satisfaction. 相似文献

In this work we propose novel markers for identifying at-risk gamblers based on the concept of sustainability. The first hypothesis here verified is that problematic gamblers oscillate between intervals of increasing wager size followed by rapid drops, probably because they exceed their economic sustainability limits. Due to the non-periodic nature of these fluctuations, the proposed marker detects a certain occurring feature, such as a rapid drop in wager size, over a wide range of fluctuation periods, drop sizes and shapes. The second marker, counting the number of games the gambler is involved in, aims at predicting possible consequences of an exceeding amount of time dedicated to gambling, that ultimately causes social and relational breakdowns. In the experimental phase we demonstrate how the adoption of these markers allows for identifying larger segments of high- and medium-risk gamblers with respect to previous research on actual betting behaviours. 相似文献

We assess students' ability to forecast future earnings by using data on expected wages self‐reported by college students with different graduation horizons. We find a significant gender gap, by which wage expectations are systematically lower for women than for men. However, women do not fully account for the gender gap in their future earnings. We also find that student performance, degree type, and graduation horizon play a relevant role in wage forecasts. In any case, students' expectations do not conform market wages but become more realistic as they approach graduation. 相似文献

Chile's economic development model changed drastically in 1973. Public policy liberalization ended and the market became the principal entity for regulating growth, including urban growth. The implementation of this new model resulted in unprecedented urban growth, markedly impacting the landscape. In mid-sized cities, this spatial growth has been especially significant. Two examples of such mid-sized cities are Chillán and Los Ángeles, located in the Biobío Region, in the so-called Central Valley. This research analyzed the land use/cover change in Chillán and Los Ángeles from 1978 to 1998, identified the patterns of urban growth and the fragmentation of the urban space, applying GIS and remote sensing tools. The main driving forces of the urban changes were analyzed and the model to predict the land use/cover changes was applied. Our results show the importance of monitoring and modeling rapid urban growth for attaining sustainable mid-sized cities in developing countries that are strongly dependent on export of natural resources. Monitoring and modeling could also help to avoid a repetition of the errors that produced the unsustainable growth characteristic of large Latin American cities. 相似文献

Problem Gambling (PG) represents a serious problem for affected individuals, their families and society in general. Previous approaches to understanding PG have been confined to only a subset of the psychobiological factors influencing PG. We present a model that attempts to integrate potential causal factors across levels of organization, providing empirical evidence from the vast literature on PG and complimentary literatures in decision-making and addiction. The model posits that components are arranged systematically to bias decisions in favor of either immediately approaching or avoiding targets affording the opportunity for immediate reward. Dopamine, Testosterone and Endogenous Opioids favor immediate approach, while Serotonin and Cortisol favor inhibition. Glutamate is involved in associative learning between stimuli and promotes the approach response through its link to the DA reward system. GABA functions to monitor performance and curb impulsive decision-making. Finally, while very high levels of Norepinephrine can induce arousal to an extent that is detrimental to sound decision-making, the reactivity of the Norepinephrine system and its effects of Cortisol levels can shift the focus towards long-term consequences, thereby inhibiting impulsive decisions. Empirical evidence is provided showing the effects of each component on PG and decision-making across behavioural, neuropsychological, functional neuroimaging and genetic levels. Last, an effect size analysis of the growing pharmacotherapy literature is presented. It is hoped that this model will stimulate multi-level research to solidify our comprehension of biased decision-making in PG and suggest pharmacological and psychological approaches to treatment. 相似文献

We argue that one reason why emerging economies borrow short term is that it is cheaper than borrowing long term. This is especially the case during crises, as during these episodes the relative cost of long‐term borrowing increases. We construct a unique database of sovereign bond prices, returns, and issuances at different maturities for 11 emerging economies from 1990 to 2009 and present a set of new stylized facts. On average, these countries pay a higher risk premium on long‐term than on short‐term bonds. During crises, the difference between the two risk premia increases and issuance shifts towards shorter maturities. To illustrate our argument, we present a simple model in which the maturity structure is the outcome of a risk‐sharing problem between an emerging economy subject to rollover crises and risk‐averse international investors. 相似文献

We introduce two types of protection premia. The unconstrained protection premium, u, is the individual's willingness to pay for certain protection efficiency given flexibility to adjust optimally the investment in protection. The constrained protection premium, c, measures willingness to pay for certain protection efficiency given no flexibility to adjust the investment in protection. u depends on tastes and wealth as well as protection technology whereas c depends only on technology. We show that c cannot exceed u and develop necessary conditions for c=u. Optimal protection for an individual with decision flexibility may be larger or smaller than that desired under no flexibility.Journal Paper No. J-15504 of the Iowa Agriculture and Home Economics Experiment Station, Ames, Iowa.
