Women continue to face discrimination due to stereotypes that place them at a disadvantage compared to men. However, not all women are stereotyped alike; instead, they are categorized into three main subtypes: traditional women (e.g., housewives), non-traditional women (e.g., career women) and sexy women. This study applies the stereotype content model (SCM) to examine how a sample of adolescents perceives the three subtypes of women in terms of status and competition, the content of the stereotypes and the emotions they feel towards the subtypes. The sample consisted of 221 adolescents, which was reduced to 163 participants (53.7% girls) between the ages of 12 and 18. Results show that sexy women are the most undervalued of the three. Likewise, housewives and career women are perceived more positively than in previous research with the adult population.  相似文献

The age of a patient is a strong moderator of both the course and the evolution of disorders/diseases. However, the effects of current age in pathological gambling (PG) have rarely been examined. The aim of this study is to explore the moderating effects of the patients’ current age in relation to personality traits and clinical outcomes of PG. A total sample of 2,309 treatment-seeking patients for PG, diagnosed according to DSM-IV criteria, participated in this study and were assessed with the Diagnostic Questionnaire for Pathological Gambling according to DSM-IV criteria, the South Oaks Gambling Screen, the Symptom Checklist, the Temperament and Character Inventory-R, and other clinical and psychopathological measures. Orthogonal polynomial contrasts showed linear trends in the relationship between age and PG: the older the patient, the more comorbid health problems were visible. The presence of additional quadratic trends also suggests that age plays a significant role in moderating the possibility of existing PG problems and general psychopathology. No interaction term was found between age and sex, but it was present for age and some personality traits: self-transcendence and reward dependence (these two traits were only relevant to the level of impairment due to PG at specific ages). This study suggests that the patients’ age influences psychopathological and clinical aspects associated to PG. Intervention in the earliest manifestations of this complex problem is essential in order to better address the need of successful treatment planning.  相似文献

This article focuses on the assassination of Guatemalan lawyer, Rodrigo Rosenberg, on 10 May 2009 and his videotaped accusation of the Colom administration, broadcast after his death. Rosenberg’s self-produced video testimony, and the ‘staging’ of his own death, opens up questions about the role of testimonio and theatricality as modes of political address. I argue that the spectacular politics of the Rosenberg video, while drawing from the testimonio genre and incorporating electronic media, mark a return to a baroque conception of politics.  相似文献

Urbanization is one of the most extreme forms of land alteration. Energy fluxes are severely affected and cities tend to have the Urban Heat Island (UHI) phenomenon, although vegetated areas inside cities could have a positive effect in mitigating UHI effect. Our main objective was to analyze the relationship between vegetation characteristics, patch size and land surface temperature (LST) in three urban areas of northwestern Argentina. We selected 38 green spaces of different size distributed in four cities, all located in the eastern foothills of the subtropical mountain forests. We used Landsat TM satellite images to calculate Normalized Difference Vegetation Index (NDVI) and LST. We assessed the net effect of patch size on LST by computing a Difference Temperature Index. At the regional scale, our results showed that vegetation patch size had a direct effect on reducing the LST of the green space. At a local scale, the analysis of the relationship between vegetation on urban green spaces and LST along a gradient of urbanization showed that green spaces with more vegetation tends to reduce LST. The results showed that largest green spaces were between 1.5 and 2.8 °C cooler than the surrounding built. In order to mitigate the UHI effect in cities, larger green spaces appear to be a possible solution.  相似文献

There is considerable debate in the area of individual quality of life research regarding the factor structure of the QOL construct that is focused on the number and composition of QOL factors and domains, and its hierarchical nature. The main goal of this study involve testing by means of confirmatory factor analyses five models that have been pointed out by recent scientific literature: firstly, an unidimensional model; secondly, a QOL model that consisted of eight inter-correlated domains proposed by Schalock and Verdugo (2002); thirdly, a model composed of these eight 1st-order factors and one 2nd- order factor; the forth and five are model with the eight 1st-order factors and three 2nd-order factor that has been denominated in other studies ‘Salamanca model’ and ‘Schalock model’. Data were collected from 3.029 social service recipients from Catalonia (Spain) who completed the GENCAT Scale, an objective QOL questionnaire. The best fit of the eight inter-correlated and 1st order domains was empirically demonstrated. Implications for future research are also discussed.  相似文献

We consider two variants of the secretary problem, the Best-or-Worst and the Postdoc problems, which are closely related. First, we prove that both variants, in their standard form with binary payoff 1 or 0, share the same optimal stopping rule. We also consider additional cost/perquisites depending on the number of interviewed candidates. In these situations the optimal strategies are very different. Finally, we also focus on the Best-or-Worst variant with different payments depending on whether the selected candidate is the best or the worst.  相似文献

In Zheng et al. (J Comb Optim 30(2):360–369, 2015) modelled a surgery problem by the one-dimensional bin packing, and developed a semi-online algorithm to give an efficient feasible solution. In their algorithm they used a buffer to temporarily store items, having a possibility to lookahead in the list. Because of the considered practical problem they investigated the 2-parametric case, when the size of the items is at most 1 / 2. Using an NF-based online algorithm the authors proved an ACR of \(13/9 = 1.44\ldots \) for any given buffer size not less than 1. They also gave a lower bound of \(4/3=1.33\ldots \) for the bounded-space algorithms that use NF-based rules. Later, in Zhang et al. (J Comb Optim 33(2):530–542, 2017) an algorithm was given with an ACR of 1.4243,  and the authors improved the lower bound to 1.4230. In this paper we present a tight lower bound of \(h_\infty (r)\) for the r-parametric problem when the buffer capacity is 3. Since \(h_\infty (2) = 1.42312\ldots \), our result—as a special case—gives a tight bound for the algorithm-class given in 2017. To prove that the lower bound is tight, we present an NF-based online algorithm that considers the r-parametric problem, and uses a buffer with capacity of 3. We prove that this algorithm has an ACR that is equal to the lower bounds for arbitrary r.  相似文献

A growing academic discussion has focused on how, in a globalized world, LGBTQ identities are shaped and influenced by different and international actors, such as the media. This article analyzes how LGBTQ people from a rural region of a Western country—Spain—feel toward their representations on TV series from English-speaking countries. Employing a qualitative approach, this research aims to depict whether the academic conceptualizations to analyze these identity conformation processes are accurate. In addition, it explores how dominating media representations are being adapted in a region that, although within the West, can serve a context of a very different nature. The results found that a major rejection of the TV series representations among participants can suggest both an inaccuracy of the conceptualizations used by some scholars to understand LGBTQ flows and a problematic LGBTQ representation in media products that goes beyond regions and spaces.  相似文献

This is the first study that empirically examines how migration influences migrants’ time use patterns in China, utilizing a mixed-method approach. We systematically estimate the migration effects on weekly hours on working, leisure, personal care and domestic responsibilities, based on data from the nationally representative 2010 Chinese Family Panel Studies. We then supplement these analyses with in-depth interviews conducted in Beijing to further understand the underlying mechanisms. Compared with urban locals, rural-to-urban migrants have longer work hours and less leisure time. The largest differences are found among men. On average, migrant men work 5 h longer and have 7 fewer hours of leisure per week than urban local men. These differences are moderated by migrants’ and their parents’ socioeconomic status, and their family responsibilities. The in-depth interviews reveal that the busier work schedules are largely motivated by the transient nature of most rural-to-urban migration and the overwhelming economic pressures for household establishment and career development.  相似文献

Background

The birth of an extremely preterm infant can disrupt normal mother–infant physical contact and the care provided by the mother. This situation has an impact on the process of bonding between the mother and the child.

Aim

The objective of this study was to describe and understand the experiences of mothers who have extremely preterm infants admitted in Neonatal Intensive Care Units with regard to their bonding process.

Methods

An interpretive, qualitative research methodology using Gadamer’s philosophical hermeneutics was carried out. A focus group and eleven in-depth, semi-structured interviews were conducted. Data were collected between June and September of 2016.

Findings

Sixteen women with a mean age of 34.4 years participated in the study. Two themes emerged from the data analysis: (1) premature labour and technological environment, a distorted motherhood, with the subthemes ‘feeling of emptiness and emotional crisis’ and ‘the complexity of the environment and care generate an emotional swing’; (2) learning to be the mother of an extremely preterm infant, with the subthemes “the difficulty of relating to a stranger” and ‘forming the bond in spite of difficulties’.

Conclusions

The bonding with extremely preterm infants is interrupted after giving birth. The maternal emotional state and the environment of the neonatal intensive care unit limit its development. Nursing care can facilitate mother–infant bonding by encouraging communication, participation in care, massaging or breastfeeding.  相似文献
