Are taxes good for your health?

The global framework for financing development, adopted in 2015, places great emphasis on mobilizing domestic resources to finance the Sustainable Development Goals, which include universal healthcare. In a recent paper Reeves et al. (2015) attribute progress towards universal healthcare to higher levels of taxation, but report a negative association between taxes on goods and services (indirect taxes) and health outcomes, which they hypothesise arises from the impact such taxes have on the real incomes of the poor. This paper revisits the relationship between tax types and health outcomes using the ICTD Government Revenue Dataset, which, crucially, isolates taxes from resource industries. As expected, we confirm increases in revenue are associated with increased public health expenditure; we find some weak evidence that greater reliance on direct taxes is associated with higher health spending and better outcomes, but no evidence that indirect taxes are deleterious to health. We argue these relationships cannot bear the weight of causal interpretation but that they offer some guidance on what to expect from increased domestic revenue mobilization

A smart environment for biometric capture

The development of large scale biometric systems require experiments to be performed on large amounts of data. Existing capture systems are designed for fixed experiments and are not easily scalable. In this scenario even the addition of extra data is difficult. We developed a prototype biometric tunnel for the capture of non-contact biometrics. It is self contained and autonomous. Such a configuration is ideal for building access or deployment in secure environments. The tunnel captures cropped images of the subject's face and performs a 3D reconstruction of the person's motion which is used to extract gait information. Interaction between the various parts of the system is performed via the use of an agent framework. The design of this system is a trade-off between parallel and serial processing due to various hardware bottlenecks. When tested on a small population the extracted features have been shown to be potent for recognition. We currently achieve a moderate throughput of approximate 15 subjects an hour and hope to improve this in the future as the prototype becomes more complete

THE IMPLICATIONS OF A NORTH AMERICAN FREE TRADE AREA FOR AGRICULTURE

This is one of two papers commissioned by the International Agricultural Trade Research Consortium on various aspects related to the agricultural sector of a prospective North American Free Trade Agreement. The companion paper to this one has been prepared by a working group chaired by Thomas Grennes, North Carolina State University. To minimize duplication with the Grennes paper, this paper has given greater attention to the general trade policy issues raised by a NAFTA, institutional factors, additional commodity detail in cereals, fruit and vegetables, and the relevance of other regional trade agreements such as the Canada-U.S. Trade Agreement. This work has also benefitted from an earlier report and its annexes, prepared for the Fraser Institute, under the direction of Tim Josling.International Relations/Trade,

Move Your Feet to the Cable Street Beat: The Cultural Praxis of Anti-Fascist Action, 1988 – 2000

The historiography of antifascism has grown substantially recently. However, scholarly attention has been disproportionally focused on the street-based and violent strategies of the movement. High-profile conflicts between antifascists and their far-right opponents have stimulated a high volume of research regarding the causes and results of their radicalization. Yet antifascism is a vast and complex movement that employs a wide variety of different strategies, the majority of which are non-violent. To address this gap in the literature, and begin to reveal the multifaceted nature of antifascist organizing, this article will explore the movement's 'cultural praxis'. That is, the way that antifascists use culture to construct a space in which they can effectively engage with the public as well as their efforts to prevent the far right from constructing such a space. Specifically, the efforts of the British militant antifascist organization Anti-Fascist Action to strategically use music and music scenes in their conflict with the far right between 1988 and 2000 shall be examined

Series solutions for a static scalar potential in a Salam-Sezgin Supergravitational hybrid braneworld

The static potential for a massless scalar field shares the essential features of the scalar gravitational mode in a tensorial perturbation analysis about the background solution. Using the fluxbrane construction of [8] we calculate the lowest order of the static potential of a massless scalar field on a thin brane using series solutions to the scalar field's Klein Gordon equation and we find that it has the same form as Newton's Law of Gravity. We claim our method will in general provide a quick and useful check that one may use to see if their model will recover Newton's Law to lowest order on the brane.Comment: 5 pages, no figure

Factors that Lead to Women Being Elected to State Legislatures

The question being posed in the study is “What factors predict the percentage of women in a state legislature?”. The units of analysis are the 50 states. The independent variables investigated are the percentage of votes for Trump in the 2016 election per state, population density per square mile, percentage population 65 and older per state, percentage with a bachelor’s degree or higher, 2018 per capita income, and the region of each state. The dependent value is the percentage of women elected in state legislatures. The relationship between the independent and dependent variables is expressed by five scatterplots and an analysis of variance (ANOVA). Among the independent variables, the percentage of votes for Trump in the 2016 election per state, percentage with a bachelor’s degree or higher, and 2018 per capita income were statistically significant. The percentage of votes for Trump in the 2016 election per state had a negative correlation while the other two had a positive correlation. The ANOVA showed that region explains 28% of the variance in the percentage of women elected into state legislatures

Seafarers’ depression and suicide

This review assesses available evidence on the frequency of and trends in depression and suicide among seafarers. Investigations of depression and suicide are scarce and the findings are inconsistent, they do, nevertheless, show indications of improvement although some recent case series do indicate that suicide remains a problem. A review of additional indicators for mental distress and lack of wellbeing supports the decline in frequency of problems, but nuances this in terms of the relative risks in different groups of seafarers, showing internal variations in the frequency of mental health issues among seafarers, with markers such as rank, type of voyage, gender, age, nationality and crew multiculturalism being relevant variables. The methodological limitations that hinder the understanding of depression and suicide in the maritime sector are identified

High-intensity, unilateral resistance training of a non-paretic muscle group increases active range of motion in a severely paretic upper extremity muscle group after stroke

Limited rehabilitation strategies are available for movement restoration when paresis is too severe following stroke. Previous research has shown that high-intensity resistance training of one muscle group enhances strength of the homologous, contralateral muscle group in neurologically-intact adults. How this cross education phenomenon might be exploited to moderate severe weakness in an upper extremity muscle group after stroke is not well understood. The primary aim of this study was to examine adaptations in force-generating capacity of severely paretic wrist extensors resulting from high-intensity, dynamic contractions of the non-paretic wrist extensors. A secondary, exploratory aim was to probe neural adaptations in a subset of participants from each sample using a single-pulse, transcranial magnetic stimulation protocol. Separate samples of neurologically-intact controls (n=7) and individuals > 4 months post stroke (n=6) underwent 16 sessions of training. Following training, one-repetition maximum of the untrained wrist extensors in the control group and active range of motion of the untrained, paretic wrist extensors in the stroke group were significantly increased. No changes in corticospinal excitability, intracortical inhibition or interhemispheric inhibition were observed in control participants. Both stroke participants who underwent TMS testing, however, exhibited increased voluntary muscle activation following the intervention. In addition, motor-evoked potentials that were unobtainable prior to the intervention were readily elicited afterwards in a stroke participant. Results of this study demonstrate that high-intensity resistance training of a non-paretic upper extremity muscle group can enhance voluntary muscle activation and force-generating capacity of a severely paretic muscle group after stroke. There is also preliminary evidence that corticospinal adaptations may accompany these gains
