Adaptation and Validation of the Polymorphous Prejudice Scale (PPS) - A Short Form In a Sample of Heterosexual Chilean College Students

ABSTRACT. Objectives: The purpose of this article is to present the psychometric characteristics of a short form of the Polymorphous Prejudice Scale (PPS; Massey, 2009), which was adapted and validated in a heterosexual Chilean population. PPS is a multidimensional measure of sexual prejudice. Methods: A nonprobabilistic (convenience) sample consisted of 422 college students. Results: Findings reveal a shortened 16-item form, grouped in four subscales, with all of the items referring to new forms of sexual prejudice. The findings showed differences based on gender, religiosity and geographic location, as hypothesized. Conclusions: Results are discussed in relation to the strengths and weaknesses of the short form of the PPS.     

Crowd work in STEM-related fields: A window of opportunity from a gender perspective?

After the Global Financial Crisis (2008) many people found new job opportunities on crowd platforms. The COVID-19 crisis reinforced this trend and virtual work is expected to increase. Although the working conditions of individuals engaged on these platforms is an emerging topic, of research, the existing literature tends to overlook the gendered dimension of the gig economy. Following a quantitative approach, based on the statistical analysis of 444 profiles (platform Freelancer.com in Spain and Argentina), we examine the extent to which the gig economy reproduces gender inequalities such as the underrepresentation of women in STEM-related tasks and the gender pay gap. While the findings reveal lower participation of women than men, this gap is not higher in Argentina than in Spain. Moreover, gender variations in hourly wages are not as marked as expected, and such differences disappear once STEM skill levels are controlled for. Asymmetry in individuals' STEM skill level provides a better explanation than gender of the hourly wage differences. This finding opens a window of opportunity to mitigate the classical gender discrimination that women face in technological fields in traditional labor markets. Finally, the paper identifies some issues concerning the methodological bias entailed by the use of an application programming interface in cyber-research, when analyzing gender inequalities.     

Examining the Relationship Between Level of Participation in Community Gardens and their Multiple Functions

Participation in community gardens improves health and well-being; however, few studies examine how often individuals need to participate to achieve these outcomes. This study examined the relationship between levels of participation in community gardens and health behaviors, psychological well-being, and perceptions of the community by surveying regular, occasional, and noncommunity garden participants in a disadvantage neighborhood (N = 115). Regular and occasional participates reported better mental health; occasional participants reported more vegetable intake, and regular participants reported more sense of community. Therefore, community practitioners may need to consider level of participation in gardening activities for some outcomes and not others.     

Does order of entry shape competitive strategies? An analysis of European mobile operators

Research on first mover advantages is interested in the performance effects of the order of entry into new markets. However, with a few exceptions, the competitive strategies used by different cohorts of entrants have not been studied. We advance research on first mover advantages by arguing that pioneers and followers differ in terms of the competitive strategy employed. Additionally, our research proposes that the different competitive strategies used evolve over time. To test our hypotheses, we use data from the European mobile industry. Our findings show that pioneers benefit from a hybrid strategy in the initial stages of the market development. However, over time, the relative position of first movers in terms of quality, prices and operating costs worsens.     

Au Chili,l'emploi progresse en nombre,non en qualité: tout dépend du contrat

Depuis 1990, les autorités chiliennes s'en remettent à la croissance économique pour créer des emplois, élever les salaires et améliorer les conditions de travail. Les résultats sont contrastés: la qualité de l'emploi n'a pas suivi les progrès quantitatifs en nombre d'emplois et en niveau de salaires. Opposant un cadre réglementaire formellement rigide à la réalité d'un marché du travail flexible, les auteurs soulignent l'importance des conditions d'emploi dans l'évaluation du marché du travail. L'examen des effets des caractéristiques des emplois et des travailleurs sur l'emploi et les revenus montre que leur premier déterminant est la détention d'un contrat de durée indéterminée.     

The random intrinsic fast initial response of one-sided CUSUM charts

This article analyses the performance of a one-sided cumulative sum (CUSUM) chart that is initialized using a random starting point following the natural or intrinsic probability distribution of the CUSUM statistic. By definition, this probability distribution remains stable as the chart is used. The probability that the chart starts at zero according to this intrinsic distribution is always smaller than one, which confers on the chart a fast initial response feature. The article provides a fast and accurate algorithm to compute the in-control and out-of-control average run lengths and run-length probability distributions for one-sided CUSUM charts initialized using this random intrinsic fast initial response (RIFIR) scheme. The algorithm also computes the intrinsic distribution of the CUSUM statistic and random samples extracted from this distribution. Most importantly, no matter how the chart was initialized, if no level shifts and no alarms have occurred before time τ?>?0, the distribution of the run length remaining after τ is provided by this algorithm very accurately, provided that τ is not too small.     

Application of E-Therapy Programs to the Social Work Practice

The many applications of the use of e-therapy in social work practice are reviewed. Salient issues regarding technological interventions, including ethical dilemmas, are elucidated. Applications discussed include the use of this evidence-based technology in treatment of substance abuse, anxiety disorders, depression, and other mental health diagnoses. Most significantly, e-therapy provides means of reaching 85% of clients who need services yet do not receive them.     

Snowball sampling: a cautionary tale involving a study of older drug users

Snowball sampling is generally seen as a highly effective sampling technique that allows for the study of difficult to reach or ‘hidden’ populations. It is also seen as a valuable tool for the study of particularly sensitive or private matters. As a result, it was chosen as the sampling method for a research study into illegal drug users over the age of 40 who are not in contact with the criminal justice authorities or treatment agencies regarding their use. However, there proved to be great difficulty in locating and interviewing potential participants using snowball sampling. Four reasons for this are proposed, and it is suggested that snowball sampling is prone to failure in particular circumstances. Thus, caution should be exercised when considering its adoption as a sample-building technique.
