Macroeconomic Policies to Increase Social Mobility and Growth in Bolivia

Poverty in Bolivia continues to be among the highest in Latin America despite decades of concerted national and international efforts to reduce it. Bolivia has meticulously followed the recommendations of the Washington consensus at the same time as external aid has been generous and foreign direct investment has boomed. Nevertheless, average productivity and incomes remain at the same low level as they were 50 years ago. This paper suggests that the failure of previous development policies is due to a lack of social mobility in the country. Without social mobility, there is little incentive for people to invest in human and physical capital, and without investment there cannot be productivity growth. In addition, the lack of social mobility implies an inefficient use of human capital, and it hinders the construction of efficient social mechanisms for redistribution and consumption smoothing over the life-cycle.Social Mobility, Development, Public Policy, Bolivia

Fully automated segmentation and tracking of the intima media thickness in ultrasound video sequences of the common carotid artery

Abstract—The robust identification and measurement of the intima media thickness (IMT) has a high clinical relevance because it represents one of the most precise predictors used in the assessment of potential future cardiovascular events. To facilitate the analysis of arterial wall thickening in serial clinical investigations, in this paper we have developed a novel fully automatic algorithm for the segmentation, measurement, and tracking of the intima media complex (IMC) in B-mode ultrasound video sequences. The proposed algorithm entails a two-stage image analysis process that initially addresses the segmentation of the IMC in the first frame of the ultrasound video sequence using a model-based approach; in the second step, a novel customized tracking procedure is applied to robustly detect the IMC in the subsequent frames. For the video tracking procedure, we introduce a spatially coherent algorithm called adaptive normalized correlation that prevents the tracking process from converging to wrong arterial interfaces. This represents the main contribution of this paper and was developed to deal with inconsistencies in the appearance of the IMC over the cardiac cycle. The quantitative evaluation has been carried out on 40 ultrasound video sequences of the common carotid artery (CCA) by comparing the results returned by the developed algorithm with respect to ground truth data that has been manually annotated by clinical experts. The measured IMTmean ± standard deviation recorded by the proposed algorithm is 0.60 mm ± 0.10, with a mean coefficient of variation (CV) of 2.05%, whereas the corresponding result obtained for the manually annotated ground truth data is 0.60 mm ± 0.11 with a mean CV equal to 5.60%. The numerical results reported in this paper indicate that the proposed algorithm is able to correctly segment and track the IMC in ultrasound CCA video sequences, and we were encouraged by the stability of our technique when applied to data captured under different imaging conditions. Future clinical studies will focus on the evaluation of patients that are affected by advanced cardiovascular conditions such as focal thickening and arterial plaques

Exploring the Representation of History and 'Slow Violence' in "Philadelphia Fire" and "The Lone Ranger and Tonto Fistfight in Heaven"

After connecting history to urban spatiality in Teju Cole's Open City, this paper develops Rob Nixon's articulation of "slow violence" to demonstrate how John Edgar Wideman and Sherman Alexie's novels depict issues of authenticity in storytelling, highlighting the limitations of representing the effects of “slow violence” on the cultural, physical, and economic welfare of marginalised communities in the aftermath of major violent events

Certified Nursing Assistants’ Perceptions of Nursing Home Patient Safety Culture: Is There a Relationship to Clinical or Workforce Outcomes?: A Dissertation

Patient safety culture (PSC) is a critical factor in creating high reliability healthcare organizations. However, few studies to date have correlated PSC measures with actual safety outcomes. In particular, nursing home studies have only recently appeared in the literature. Nursing homes differ from hospitals in that the vast majority of direct care is provided by certified nursing assistants (CNAs), not licensed nurses. Thus nursing home PSC could differ in important ways from PSC in acute care institutions. This dissertation was a secondary data analysis that examined whether CNAs’ perceptions of patient safety culture were correlated with clinical outcomes in a random sample of 74 nursing homes in five randomly selected states. This study matched CNA PSC survey data using the Hospital Survey of Patient Safety Culture (HSOPSC) with Minimum Data Set (MDS), Area Resource File (ARF) and Online Survey Certification and Reporting (OSCAR) data from those same homes during the first two quarters of 2005. In the original study, 1579 nurse aides out of 2872 completed the survey, for a 55% response rate. In addition to clinical outcomes, this study examined the relationship between CNA PSC scores and staff turnover. The relationship between certain demographic variables, such as level of education, tenure as a CNA, and PSC scores was evaluated. The relationship between certain facility characteristics, such as profit status and bed occupancy was also assessed. An exploratory factor analysis of the original HSOPSC instrument was re-run for this nursing home CNA sample. Data were analyzed using Poisson regression and multilevel techniques; descriptive statistics were compiled for demographic data. Major findings from the regression analyses and combined GEE models suggest that certain factors, such as CNA turnover and LPN staffing may predict CNA PSC scores. CNA PSC scores were associated with rates of falls and restraint use, but were not associated with differences in pressure ulcer rates in this sample. Few associations for CNA PSC with individual subscales were identified. The exploratory factor analysis revealed some potential differences in how items and subscales factored in this nursing home CNA population. This dissertation represents an important step in the evaluation of CNA PSC in nursing homes and the relationship of PSC to safety outcomes. Future work on nursing home PSC and clinical and workforce outcomes is described
