Abstract

The purpose of this study is to validate a Spanish-speaking version of the internal corporate social responsibility questionnaire (ICSR Q), a questionnaire that is based on the social exchange theory and assess the perception of employees related to seven internal practices that reflect how responsible are organizations toward its workforce The questionnaire was applied to two samples of Colombian employees (N = 433). Confirmatory factor analysis revealed that the original structure of seven factors was maintained in the Spanish—speaking version, with appropriate levels of convergent and discriminant validity. Positive and significant relationships were found between internal corporate social responsibility and organizational commitment, both at affective and normative levels. Finally, type of employment contract (permanent or fixed term) implied significant differences in employee perceptions of internal corporate social responsibility. Our results provide evidence for the validity of the Spanish—speaking version of the internal corporate responsibility scale, suggesting its future application in investigations of internal aspects of corporate social responsibility in Spanish-speaking organizational contexts.

Abstract

Programs implementing community-based directly observed therapy (DOT) have demonstrated success in the treatment of patients with tuberculosis. However, given complexities in the management and treatment of patients infected with multidrug-resistant tuberculosis (MDR-TB), the utilization of community-based DOT to treat MDR-TB patients has only recently been successfully attempted. We describe the first such program and highlight the crucial components and most critical challenges to creating a successful community-based MDR-TB treatment program.

Abstract

Background For treating multidrug-resistant tuberculosis (MDR TB), the World Health Organization (WHO) recommends a regimen of at least four second-line drugs that are likely to be effective as well as pyrazinamide. WHO guidelines indicate only marginal benefit for regimens based directly on drug susceptibility testing (DST) results. Recent evidence from isolated cohorts suggests that regimens containing more drugs may be beneficial, and that DST results are predictive of regimen effectiveness. The objective of our study was to gain insight into how regimen design affects treatment response by analyzing the association between time to sputum culture conversion and both the number of potentially effective drugs included in a regimen and the DST results of the drugs in the regimen. Methods and Findings We analyzed data from the Preserving Effective Tuberculosis Treatment Study (PETTS), a prospective observational study of 1,659 adults treated for MDR TB during 2005-2010 in nine countries: Estonia, Latvia, Peru, Philippines, Russian Federation, South Africa, South Korea, Thailand, and Taiwan. For all patients, monthly sputum samples were collected, and DST was performed on baseline isolates at the US Centers for Disease Control and Prevention. We included 1,137 patients in our analysis based on their having known baseline DST results for at least fluoroquinolones and second-line injectable drugs, and not having extensively drug-resistant TB. These patients were followed for a median of 20 mo (interquartile range 16-23 mo) after MDR TB treatment initiation. The primary outcome of interest was initial sputum culture conversion. We used Cox proportional hazards regression, stratifying by country to control for setting-associated confounders, and adjusting for the number of drugs to which patients' baseline isolates were resistant, baseline resistance pattern, previous treatment history, sputum smear result, and extent of disease on chest radiograph. In multivariable analysis, receiving an average of at least six potentially effective drugs (defined as drugs without a DST result indicating resistance) per day was associated with a 36% greater likelihood of sputum culture conversion than receiving an average of at least five but fewer than six potentially effective drugs per day (adjusted hazard ratio [aHR] 1.36, 95% CI 1.09-1.69). Inclusion of pyrazinamide (aHR 2.00, 95% C11.65-2.41) or more drugs to which baseline DST indicated susceptibility (aHR 1.65, 95% CI 1.48-1.84, per drug) in regimens was associated with greater increases in the likelihood of sputum culture conversion than including more drugs to which baseline DST indicated resistance (aHR 1.33, 95% C11.18-1.51, per drug). Including in the regimen more drugs for which DST was not performed was beneficial only if a minimum of three effective drugs was present in the regimen (aHR 1.39, 95% C11.09-1.76, per drug when three effective drugs present in regimen). The main limitation of this analysis is that it is based on observational data, not a randomized trial, and drug regimens varied across sites. However, PETTS was a uniquely large and rigorous observational study in terms of both the number of patients enrolled and the standardization of laboratory testing. Other limitations include the assumption of equivalent efficacy across drugs in a category, incomplete data on adherence, and the fact that the analysis considers only initial sputum culture conversion, not reversion or long-term relapse. Conclusions MDR TB regimens including more potentially effective drugs than the minimum of five currently recommended by WHO may encourage improved response to treatment in patients with MDR TB. Rapid access to high-quality DST results could facilitate the design of more effective individualized regimens. Randomized controlled trials are necessary to confirm whether individualized regimens with more than five drugs can indeed achieve better cure rates than current recommended regimens., Introduction World Health Organization (WHO) guidelines for the treatment of multidrug-resistant tuberculosis (MDR TB) recommend a regimen consisting of at least four second-line drugs that are likely to be effective [...]

45. We Are Very Similar but Not Really: The Moderating Role of Cultural Identification for Refugee Resettlement of Venezuelans in Colombia.

Abstract

This study aims to test the theoretical model of career adaptability of refugees to investigate the dynamics of successful resettlement. The theoretical model is grounded on career construction and social network theory. We employ quantitative and qualitative methodologies to test the model in a sample of Venezuelans living and working in Colombia. The quantitative results provide partial support for Campion's model. However, we test an alternative model and find that career adaptability has a direct relationship with subjective resettlement (i.e., life satisfaction and psychological health). In addition, cultural identification plays a buffering role on the harmful effects of discrimination on subjective resettlement. Qualitative results from eight in-depth interviews shed light on the process of refugee resettlement, thus revealing the role of social networks. Our study contributes to previous research on refugees by testing, adapting, and expanding a novel model of work resettlement and focusing on a group of refugees transitioning from one emerging country to another emerging country.

Abstract

The purpose of this study is to validate the Spanish version of the Work Design Questionnaire (WDQ; Morgeson & Humphrey, 2006). Employees from three Colombian samples completed the questionnaire (N = 831). Confirmatory factor analyses revealed a 21-factor structure (χ²/df ratio = 2.40, SRMR = .06, RMSEA = .04, CFI = .90) with adequate levels of convergent and discriminant validity. Additional support for construct validity was found from significant differences among different occupational groups (professional and nonprofessional, health-focused, commercial, and manufacturing workers). Furthermore, knowledge, social, and work context characteristics showed incremental validity over task characteristics on job satisfaction and perceived performance. Possible interpretations of these relationships are offered. It is concluded that the study provides evidence for the validity of a Spanish version of the scale, and presents further support for the generalization of the 21-factor structure of work design characteristics in different cultural settings. El propósito de este estudio es validar la versión española del Work Design Questionnaire (WDQ; Morgeson y Humphrey, 2006). Tres muestras de empleados colombianos completaron el cuestionario (N = 831). El análisis factorial confirmatorio reveló una estructura de 21 factores (razón χ²/gl = 2.40, SRMR = .06, RMSEA = .04, CFI = .90) con adecuados niveles de validez convergente y discriminante. Se encontraron diferencias significativas entre diferentes grupos ocupacionales (profesionales, no profesionales, trabajadores de la salud, comerciales y de producción). También se encontró que las características del conocimiento, sociales y contextuales aportaron validez incremental sobre la satisfacción laboral y el desempeño percibido. Se ofrecen posibles interpretaciones de estas relaciones. Se concluye que el estudio proporciona evidencia suficiente sobre la validez de la versión española de la escala, lo que presenta más apoyo para la generalización de la estructura del modelo de características del trabajo de 21 factores en diferentes contextos culturales.

Abstract

La venta y consumo de Sustancias Psicoactivas (SPA) dentro de la Universidad Nacional de Colombia ha representado una constante preocupación para la comunidad universitaria. El presente estudio aborda esta problemática desde la perspectiva de las actitudes, construyendo un instrumento evaluador de la actitud frente a la venta y consumo de SPA entre los estudiantes con una escala tipo Likert de 21 items. El instrumento se aplicó a una muestra de 1321 estudiantes pertenecientes a 11 facultades de la Universidad. Los resultados indicaron una actitud en general negativa frente al consumo y venta de SPA, siendo las facultades de Medicina, Enfermería y Odontología las que obtuvieron la actitud más negativa en la prueba; mientras que las facultades de Artes y Ciencias Humanas, fueron las que puntuaron más alto, indicando una actitud más favorable. Adicionalmente, no existieron diferencias entre hombres y mujeres, pero tanto la edad como el semestre indicaron relaciones inversas, donde la actitud era más negativa entre los rangos superiores de edad y semestre, que entre los inferiores. Finalmente, se discuten las relaciones entre el grupo de referencia de los estudiantes, tipo de entrenamiento, diseño ambiental de la universidad y la actitud de los estudiantes frente a la venta y consumo de SPA

48. Two Birds with One Stone? The Impact of Entrepreneurial Self-Efficacy on Workability and Employment.

Author

Abstract

Entrepreneurial self-efficacy (ESE) is essential for entrepreneurial success. Entrepreneurship scholars have suggested broadening its scope to analyze its effects in populations other than entrepreneurs. Drawing upon self-efficacy theory, we propose that ESE predicts employability via workability. Furthermore, we propose that work-from-home hours and occupational type (white collar vs. blue collar) are boundary conditions. Adopting a panel study design, we tested our hypotheses within a sample of employees (N = 681). Data were collected between July (T1) and August 2020 (T2). Linear regression analyses showed that ESE predicts employability through workability and this relationship is moderated by work-from-home hours and occupation type. We discuss the implications of adopting entrepreneurial lenses to understand the link between entrepreneurial behavior and career success outcomes in general employee populations, and the ontological relationship between ESE and our criteria. Finally, we offer recommendations for practitioners to improve workability and employability in the "new normal." [ABSTRACT FROM AUTHOR]
