How social networks affect policy implementation: An analysis of street-level bureaucrats' performance regarding a health policy

Policy implementation is an interactive process between citizens and street-level bureaucrats. Although the literature has already addressed different factors that influence discretion, there is still a gap in understanding if and how bureaucrats' relational profiles affect policy implementation. This article analyses bureaucrats' interactions and the relational environments in which they exercise their discretion. The hypothesis is that bureaucrats' different relational profiles specify policy implementation at the street level. We study bureaucrats in a Brazilian health care programme involving community workers that requires regular visits to beneficiary families' homes. The research departs from ethnography and network analyses with workers from three very different contexts. We analyse bureaucrats' practices, the discursive styles mobilized in their interactions, and their personal networks. The results show that organizational factors are central to explain variations in practices, and their relational profiles highly influence the discursive styles used by bureaucrats in their interactions with citizens. The article concludes that relational elements can affect the exercise of discretion and influence interactions at the street level and should be incorporated more systematically in the implementation literature.     

Ergonomics and design in a ischial support proposal for the Medellin metro, Colombia

This project, developed by the Design Studies Research Group at the Universidad Pontificia Bolivariana (UPB), presents a design proposal focused on human factors for ischial support for the stations of the Medellín Metro. An initial pilot scheme was developed on Platform 'A' of San Antonio - the most important transfer station. The methodology of the Ergonomics Research Division at UPB constituted the basis of the project. This methodology observes, analyses and draws conclusions of the conditions that optimize the User-Product-Context nexus, and in doing so defines design requirements which, in this proposal, centered on the needs of the users of the Medellín Metro. The Experimental Morphology Research Division provided technical support in the form of modelling, production and structural testing of the object. The proposal includes thematic units, themes and priority components for analysis and application in the design process. In addition, the project generates certain activities and moments that future designers can develop in a parallel manner, coherent with the vision of ergonomics. The methodology focused on the requirements of the users and took into account the existing space (the Metro System), thus establishing relationships of use that were coherent with the principles of ergonomics and design.     

Vulnerability to individual and aggregate poverty

We propose families of measures for vulnerability to both individual and aggregate poverty. We view vulnerability as the burden caused by the threat of poverty. Exposure to states of the world where hardship may strike causes distress ex-ante, even if ex-post the dice are benign and poverty (consumption below a critical norm) does not materialise. We ensure our measures meet a set of desirable axioms—in the case of aggregate vulnerability, this set includes sensitivity to the degree of correlation of outcomes across individuals. We argue that individual vulnerability levels are not enough to compose the aggregate picture, e.g. because society may be wary of the threat of simultaneous, widespread poverty. We illustrate with data from Ethiopia, where rainfall risks are found to raise vulnerability to poverty despite sustained increases in consumption.     

Perceived Community Cohesion and the Stress Process in Youth

Using survey data from two youth samples, one rural and one urban, we examine the role and significance of perceived community cohesion in the stress process. In particular, we assess the extent to which community attachment and detachment are related to depressed mood, problem substance use, and delinquency net of social statuses, stress exposure, and personal attributes. In addition, we explore the degree to which those dimensions of community cohesion explain or condition the links between the above stress‐process components (e.g., social statuses, stress exposure, and personal attributes) and well‐being. We find remarkably similar results across samples: community attachment is related to lower odds of problem substance use and delinquency; community detachment is related to higher levels of depressed mood, problem substance use, and delinquency; and community attachment buffers the link between stress and problem substance use. With respect to depressed mood, however, the rural youth show greater vulnerability to stress than the urban youth and unique benefits from community attachment compared to the latter. Our findings highlight the roles of community attachment and detachment in the stress process and underscore the importance of each for youth well‐being in rural and urban settings.     

Migration and Development: Mexico and Turkey

Mexico and Turkey are among the world's leading labor‐sending nations, with about 11 million Mexican‐born and 3.5 million Turkish‐born persons abroad in 2006. After two decades of uneven growth and job creation as well as persisting poverty and inequality, there are debates within both countries asking whether economic reforms have gone far enough to put the economy on a stable footing for sustained and equitable growth, or whether emigration (pressure) will continue. Some Mexicans are seeking to deepen North American Free Trade Agreement, while most Turks support entry into the European Union as a way of speeding economic growth.     

Global and local tests to assess stationarity of Markov transition models

We present global and local likelihood-based tests to evaluate stationarity in transition models. Three motivational studies are considered. A simulation study was carried out to assess the performance of the proposed tests. The results showed that they present good performance with the control of the type-I error, especially for ordinal responses, and control of the type-II error, especially for the nominal case. Asymptotically they are close to the classical test performance. They can be executed in a single framework without the need to estimate the transition probabilities, incorporating both categorical and continuous covariates, and used to identify sources of non-stationarity.     

An alternative method for evaluating stationarity in transition models

Transition models are an important framework that can be used to model longitudinal categorical data. A relevant issue in applying these models is the condition of stationarity, or homogeneity of transition probabilities over time. We propose two tests to assess stationarity in transition models: Wald and likelihood-ratio tests, which do not make use of transition probabilities, using only the estimated parameters of the models in contrast to the classical test available in the literature. In this paper, we present two motivating studies, with ordinal longitudinal data, to which proportional odds transition models are fitted and the two proposed tests are applied as well as the classical test. Additionally, their performances are assessed through simulation studies. The results show that the proposed tests have good performance, being better for control of type-I error and they present equivalent power functions asymptotically. Also, the correlations between the Wald, likelihood-ratio and the classical test statistics are positive and large, an indicator of general concordance. Additionally, both of the proposed tests are more flexible and can be applied in studies with qualitative and quantitative covariates.     

Evaluation and control of ergonomics actions in federal public service: the case of FIOCRUZ-RJ

This article presents information about the development of the dissertation. Deals with the production of ergonomic diagnosis in the environments and work processes of an important center of research and development in Public Health, FIOCRUZ. Critically evaluates the performance of a team promoting and facilitating the process of implementing ergonomic changes suggested. Through analysis of documents and statements by some managers and representatives of Human Resources was possible to identify the factors that facilitate and hinder the implementation process, linking them to the organization of the institution and conduct of the agents involved. Finally, it makes a reflection on practice, results and developments involved in the processes of change initiated by the ergonomic actions, proposing its replication along with other institutes of the Civilian Personnel of Federal Public Administration.
