An analysis of employment intensity of sectoral output growth in Botswana

3Despite an impressive macroeconomic growth record in Botswanaover the past four decades, high unemployment and poverty incidences remain persistent and an intractable challenge of macroeconomic management in the country. The study explores the employment intensity of sectoral output growth in Botswana with a view to identifying key sectors of the Botswana economy that are employment intensive. To achieve this objective, the study used both simple elasticities and econometric procedures to provide empirical evidence concerning the extent to which economic growth that has occurred in Botswana is employment intensive and in which sectors. The fi ndings confi rmed the low labour absorptivecapacity of the Botswana economy at the aggregate and at sectoraldecompositions, suggesting the notion that growth performance inthe country is, after all, ’jobless growth’. With respect to policy, thestudy recommends a successful mineral-led economy that is able todiversify into sectors and activities that are by nature relatively morelabour-intensive

EEG Classification based on Image Configuration in Social Anxiety Disorder

The problem of detecting the presence of Social Anxiety Disorder (SAD) using Electroencephalography (EEG) for classification has seen limited study and is addressed with a new approach that seeks to exploit the knowledge of EEG sensor spatial configuration. Two classification models, one which ignores the configuration (model 1) and one that exploits it with different interpolation methods (model 2), are studied. Performance of these two models is examined for analyzing 34 EEG data channels each consisting of five frequency bands and further decomposed with a filter bank. The data are collected from 64 subjects consisting of healthy controls and patients with SAD. Validity of our hypothesis that model 2 will significantly outperform model 1 is borne out in the results, with accuracy $6$--$7\%$ higher for model 2 for each machine learning algorithm we investigated. Convolutional Neural Networks (CNN) were found to provide much better performance than SVM and kNNs

Domainâ specific impairment in cognitive control among remitted youth with a history of major depression

AimImpairment in neuropsychological functioning is common in major depressive disorder (MDD), but it is not clear to what degree these deficits are related to risk (e.g. trait), scar, burden or state effects of MDD. The objective of this study was to use neuropsychological measures, with factor scores in verbal fluency, processing speed, attention, setâ shifting and cognitive control in a unique population of young, remitted, unmedicated, early course individuals with a history of MDD in hopes of identifying putative trait markers of MDD.MethodsYouth aged 18â 23 in remission from MDD (rMDD; n = 62) and healthy controls (HC; n = 43) were assessed with neuropsychological tests at two time points. These were from four domains of executive functioning, consistent with previous literature as impaired in MDD: verbal fluency and processing speed, conceptual reasoning and setâ shifting, processing speed with interference resolution, and cognitive control.ResultsrMDD youth performed comparably to HCs on verbal fluency and processing speed, processing speed with interference resolution, and conceptual reasoning and setâ shifting, reliably over time. Individuals with rMDD demonstrated relative decrements in cognitive control at Time 1, with greater stability than HC participants.ConclusionMDD may be characterized by regulatory difficulties that do not pertain specifically to active mood state or fluctuations in symptoms. Deficient cognitive control may represent a trait vulnerability or early course scar of MDD that may prove a viable target for secondary prevention or early remediation.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/138407/1/eip12253_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/138407/2/eip12253.pd

Ethnic Fragmentation and Police Spending: Social Identity and a Public Good

We present evidence that more ethnically fragmented communities spend, all else equal, more on police services than less fragmented communities. We introduce a model of spending on police services which we use to interpret the data. In this model, we assume that the decision to commit a crime is a rational consideration of the costs and benefits and that spending on police services reduces the attractiveness of committing a crime. We also assume that being a victim of crime affects a loss in utility. However this victimization cost, if victim and perpetrator are a different ethnicity, is greater than or equal to that if the perpetrator is the same ethnicity. A consequence of the model is that a higher level of spending on police services is associated with more ethnically fragmented communities only when agents suffer this differential cost of victimization. These results contribute to our understanding of the stylized fact that spending on police services is increasing at a time in which crime rates are falling. Further, our results provide empirical support for the contention that people have a larger cost of victimization when the perpetrator is a different ethnicity
