Economic Crisis and Job Quality in Spain: A Multi-dimensional and Micro-data Empirical Approach

Through a representative sample of 9,100 and 8,755 employees in 2008 and 2010, and a using two-stage structural equation model, this article empirically analyses the multi-dimensional determinants (direct effects) of job quality in Spain. The research concludes that: #1 despite the economic crisis, job quality improved over the analysis period; #2 there was a shift in job quality explanation towards a more complete model with greater preponderance of the dimensions connected with the workplace relationships, work intensity, working conditions and work–life balance in detriment to dimensions connected with the intrinsic job quality and extrinsic rewards. These results suggest the importance of the working environment and social relationships, beyond the quality of the workplace, as important tools of employment public policy to improve labor markets and to overcoming the economic crisis.     

Impacts of urban sprawl on species richness of plants,butterflies, gastropods and birds: not only built-up area matters

Urban growth is a major factor of global environmental change and has important impacts on biodiversity, such as changes in species composition and biotic homogenization. Most previous studies have focused on effects of urban area as a general measure of urbanization, and on few or single taxa. Here, we analyzed the impacts of the different components of urban sprawl (i.e., scattered and widespread urban growth) on species richness of a variety of taxonomic groups covering mosses, vascular plants, gastropods, butterflies, and birds at the habitat and landscape scales. Besides urban area, we considered the average age, imperviousness, and dispersion degree of urban area, along with human population density, to disentangle the effects of the different components of urban sprawl on biodiversity. The study was carried out in the Swiss Plateau that has undergone substantial urban sprawl in recent decades.Vascular plants and birds showed the strongest responses to urban sprawl, especially at the landscape scale, with non-native and ruderal plants proliferating and common generalist birds increasing at the expense of specialist birds as urban sprawl grew. Overall, urban area had the greatest contribution on such impacts, but additional effects of urban dispersion (i.e., increase of non-native plants) and human population density (i.e., increases of ruderal plants and common generalist birds) were found. Our findings support the hypothesis that negative impacts of urban sprawl on biodiversity can be reduced by compacting urban growth while still avoiding the formation of very densely populated areas.     

Overcoming medication refusal using a patient-centered approach

The refusal of psychotropic medication is a challenge faced by many healthcare providers when treating patients with mental illness. Controversy surrounds medication refusal because some mental health professionals believe that psychiatric patients should be forced to take medications for the safety of the general public, while patients are often acutely aware of potential lifelong adverse side effects and are sometimes reluctant to comply. The proposed alternative to this problem begins with developing the patient-provider relationship through a patient-centered approach. This approach emphasizes the individual needs of patients and creates opportunities for input from patients about their care, which helps form relationships of mutual trust and respect between patients and providers. This article explores the literature to: (1) understand some of the challenges and controversies involved in patient medication refusal from a clinical and societal level; (2) identify some issues in a patient-centered approach; and (3) make some brief clinical and policy recommendations that might help to bring about an increase in the use of patient-centered care. Hopefully, as efforts are made toward a patient-centered approach, increased psychotropic medication adherence and decreased medication coercion will result as providers listen and act upon the needs of their patients.     

What are Research Expectations? A Comparative Study of Different Academic Disciplines

This paper is intended to assist professors, administrators, librarians and other members of university level committees that must consider research expectations and research quality in academic fields that they lack. While this is not a problem for field experts, it is a difficulty when people are asked to make decisions in areas of study other than their own. This is commonly the case for senior university professors, librarians and administrators in regards to university wide decisions. The paper investigates this gap, through a study of 27 academic fields in 348 highly regarded universities. We find that there are almost always statistically significant differences in activity between academic fields, regardless of the metric one considers. However, it is possible to understand these differences by comparing the distribution of a known academic field to that of a field that one is not familiar with. Tables and information are provided to assist in the comparison of different fields of study on metrics such as: departmental publications and researcher level metrics of publications, citations, H-index, and total number of co-authors. The information can also be used to support decisions associated with promotion to senior posts such as endowed chairs and professorships. Information regarding specific universities and researchers are included in the data supplement.     

Introductory Statistics Textbooks and the GAISE Recommendations

The six recommendations made by the Guidelines for Assessment and Instruction in Statistics Education (GAISE) committee were first communicated in 2005 and more formally in 2010. In this article, 25 introductory statistics textbooks are examined to assess how well these textbooks have incorporated the three GAISE recommendations most relevant to implementation in textbooks (statistical literacy and thinking; use of real data; stress concepts over procedures). The implementation of another recommendation (using technology) is described but not assessed. In general, most textbooks appear to be adopting the GAISE recommendations reasonably well in both exposition and exercises. The textbooks are particularly adept at using real data, using real data well, and promoting statistical literacy. Textbooks are less adept—but still rated reasonably well, in general—at explaining concepts over procedures and promoting statistical thinking. In contrast, few textbooks have easy-usable glossaries of statistical terms to assist with understanding of statistical language and literacy development. Supplementary materials for this article are available online.     

Shared frailty model based on reversed hazard rate for left censored data

Frailty models are used in the survival analysis to account for the unobserved heterogeneity in the individual risks to disease and death. To analyze the bivariate data on related survival times (e.g., matched pairs experiments, twin or family data), the shared frailty models were suggested. In this article, we introduce the shared gamma frailty models with the reversed hazard rate. We develop the Bayesian estimation procedure using the Markov chain Monte Carlo (MCMC) technique to estimate the parameters involved in the model. We present a simulation study to compare the true values of the parameters with the estimated values. We apply the model to a real life bivariate survival dataset.     

Assessing the Validity and Reliability of the Perceptions of the Consent to Sex Scale

Although sexual assault prevention education tends to focus on consent promotion as a means to reduce rates of sexual assault, little is known about how college students consent to sexual activity. The current study aimed to better understand college students' consent via the systematic development of the Consent to Sex Scale (CSS), utilizing mixed methods via three phases and two waves of data collection. In Phase 1, qualitative data were collected from college students (n = 185) to provide a foundation for item writing. In Phase 2, closed-ended items were written for a quantitative instrument and reviewed by a team of experts. In Phase 3, a quantitative survey, including items written in Phase 2, was administered to college students (n = 685); the measure was assessed for its psychometric properties. Exploratory factor analysis was utilized, resulting in a five-factor solution. The CSS and corresponding factors demonstrated high internal consistency reliability and expected gender differences, supporting the construct validity of the measure. The CSS assesses college students' cues for indicating consent to sex, a construct not addressed by previous measures. The validated scale may be useful in future research to better understand how consent relates to other behaviors or constructs.     

The Medical Assessment of Migrants: Current Limitations and Future Potential

Attempts to control the importation of infectious diseases through the medical screening and evaluation of immigrants and refugees represent the modern application of some of the earliest recorded public health interventions.
States with long-standing immigration programmes continue to require the medical examination and screening of migrants for certain diseases. In some instances, the public health effectiveness of these immigration medical assessments is of questionable value when considered from a population health basis.
This article reviews current practices and describes recent studies where more modern and epidemiologically based immigration medical interventions have been undertaken. A more effective immigration medical assessment process is proposed through the use of results of this more empirical approach to immigration medical screening.
