The Impact of Transnational Conflicts on Christian-Muslim Relations in Nigeria (2001-2006)

This Master’s Thesis examines transnational conflicts and Christian-Muslim relations in Nigeria between the years 2001 and 2006. It focuses on two major transnational conflicts: The September 11, 2001 attacks in the United States and the Danish cartoon controversy of 2005/2006. It discusses the impact of these transnational conflicts on Christian-Muslim relations in Nigeria in the light of the implementation of the Sharia Law in some northern Nigerian states and the improved access to the broadcast media and mobile telephone communication in Nigeria. By underscoring the relationship between transnational conflicts and the local context, this study provides a new perspective for understanding Christian-Muslim relations in Nigeria

The impact of high latitudes on the optical design of solar systems

Irradiation distribution functions based on the yearly collectible energy have been derived for two locations; Sydney, Australia which represents a mid-latitude site and Stockholm, Sweden, which represents a high latitude site. The strong skewing of collectible energy toward summer solstice at high latitudes dictates optimal collector tilt angles considerably below the polar mount. The lack of winter radiation at high latitudes indicates that the optimal acceptance angle for a stationary EW-aligned concentrator decreases as latitude increases. Furthermore concentrator design should be highly asymmetric at high latitudes.

The impact of price changes on volume sales of alcoholic beverages in Sweden, 2006-2013

We evaluate whether price elasticities on registered alcohol have changed in the last ten years in Sweden, in particular with regard to the investigation by Asplund et al (2007). We also investigate the fiscal effects of such changes. According to our estimates, price elasticities have increased, and these increases may have substantial effects on estimated changes in tax revenues when commodity tax rates are changed. In particular, commodity tax rates on spirits may have reached “Laffer territory” where tax increases may actually lower tax revenues.

The effects of adult literacy on earnings and employment

This paper provides evidence of the effects of adult literacy on individuals’ income and employability in Brazil based on information obtained from the monthly employment survey (PME). The OLS results indicate that after controlling for observable characteristics, there is a 21.25% increase in wages for individuals who become literate; however, there is no significant impact on employability. Moreover, the findings show an 8.1% increase in the probability of being employed in the formal sector. We also explore the longitudinal structure of the dataset to control for unobservable fixed characteristics of individuals. The fixed-effects estimators show smaller effects compared to the OLS estimators. We find that literacy has a 4.4% effect on wages and a 4.3% impact on the probability of being formally employed. The effects are significantly different from zero.

The impact of daycare attendance on math test scores for a cohort of 4th graders in Brazil

We estimate the impact of having attended center-based daycare institutions during early childhood on Math test scores at the 4th grade of elementary school. Because enrollment in daycare centers may depend on unobservable character-istics of the family and the child, we build and estimate a structural model of endogeneous choice of school to deal with the selectivity problem. We nd that attendance to daycare institutions is associated with a gain of approximately 0,04 standard deviation in Math test scores. This result is important to the extent our OLS results as well as most of the studies for Brazil nd no e¤ect associated to daycare attendance, suggesting selectivity may play a role on this finding.

The impact of past hyperinflation on current household investment behavior

Neste estudo é proposto que a instabilidade macroeconômica extrema causada pela hiperinflação nas décadas de 80 e 90 no Brasil causou um efeito de longo prazo no comportamento de poupança dos indivíduos. Usando dados da Pesquisa Nacional por Amostra de Domicílio (PNAD) de 2009 e 2011 e um questionário complementar, encontramos três evidências significantes: (1) indivíduos que possuem memória do período de hiperinflação no Brasil tem uma menor probabilidade de participar do mercado de ações; (2) há uma forte evidência que pessoas que estavam em idade formativa durante a hiperinflação são menos dispostos de possuir algum tipo de instrumento financeiro do que pessoas que tiveram a experiência desse choque macroeconômico em outros períodos de suas vidas; (3) mulheres solteiras são muito mais prováveis de ter uma poupança financeira que homens solteiros.

The impact of mayor leadership on education: evidence from Brazil

What are the impacts of female mayors on education? It is well known that in Brazil, like in many other countries around the globe, women are underrepresented in political posts. Understanding the impacts of this discrepancy on policy choice and redistribution across many areas of inquiry is, therefore, an important research endeavor. Extant literature shows a strong link between women and the economic development of the areas they govern, specifically that they provide public goods relevant to the needs of women constituents. However, despite the efforts to explore the impacts of gender political leaders, we still do not know what is the consequence of gender on policy outcomes. Exploring a rich dataset on Brazilian municipalities, I intend to enrich the literature on the role of female politicians on politics. I employ a regression discontinuity design using Brazilian elections and indicators on education based on the basic education development index (IDEB), education expenditures and local policies. I find that municipalities where a woman enters into power do not perform better on education and do not present more investments or policies to improve education.

The impact of physical exercise on the gastrointestinal tract

Purpose of reviewPhysical exercise can be both beneficial and harmful for the gastrointestinal tract in a dose-effect relationship between its intensity and health. Mild-to-moderate intensity exercises play a protective role against colon cancer, diverticular disease, cholelithiasis and constipation, whereas acute strenuous exercise may provoke heartburn, nausea, vomiting, abdominal pain, diarrhea and even gastrointestinal bleeding. This review focuses on mechanisms involved in those symptoms and their associations with type of exercises in humans.Recent findingsOne quarter to one half of elite athletes are hampered by the gastrointestinal symptoms that may deter them from participation in training and competitive events. Vigorous exercise-induced gastrointestinal symptoms are often attributed to altered motility, mechanical factor or altered neuroimmunoendocrine secretions. Training, lifestyle modifications, meal composition, adequate hydration and avoidance of excessive use of some medications are the recommendations.SummaryStrenuous exercise and dehydrated states would be the causes of gastrointestinal symptoms referred by 70% of the athletes. Gut ischemia would be the main cause of nausea, vomiting, abdominal pain and (bloody) diarrhea. The frequency is almost twice as high during running than during other endurance sports as cycling or swimming and 1.5-3.0 times higher in the elite athletes than the recreational exercisers.

Impact of oxygen atmosphere on piezoelectric properties of CaBi2Nb2O9 thin films

CaBi2Nb2O9 (CBNO) thin films were deposited on platinum-coated silicon substrates by the polymeric precursor method, and were annealed in air and in an oxygen atmosphere. The structure, surface morphology and electrical properties of CBNO thin films have been investigated. The presence of an oxygen atmosphere during crystallization of the films affected the structure perfection and morphology, as well as ferroelectric and piezoelectric properties. A reduction in P-r and piezoelectric coefficient, an increase of V-c and displacement of the Curie point is evident in the films crystallized in an oxygen atmosphere. The impact of exposure to the oxygen atmosphere on the creation of defects caused by bismuth and oxygen vacancies between layers was also investigated by X-ray photoelectron spectroscopy.

The acid-base impact of free water removal from, and addition to, plasma

Water, compared with plasma at a pH of 7.4, is a weak acid. The addition of free water to a patient should have an acidifying effect (dilutional acidosis) and the removal of it, an alkalinizing effect (concentrational alkalosis). The specific effects of free water loss or gain in a relatively complex fluid such as plasma has, to the authors' knowledge, not been reported. This information would be useful in the interpretation of the effect of changes in free water in patients. Plasma samples from goats were either evaporated in a tonometer to 80% of baseline volume or hydrated by the addition of distilled water to 120% of baseline volume. The pH and partial pressure of carbon dioxide, sodium, potassium, ionized calcium, chloride, lactate, phosphorous, albumin, and total protein concentrations were measured. Actual base excess (ABE), standard bicarbonate, anion gap, strong ion difference, strong ion gap, unmeasured anions, and the effects of sodium, chloride, phosphate, and albumin changes on ABE were calculated. Most parameters changed 20% in proportion to the magnitude of dehydration or hydration. Bicarbonate concentration, however, increased only 11% in the evaporation trial and decreased only -2% in the dehydration trial. The evaporation trial was associated with a mild, but significant, metabolic alkalotic effect (ABE increased 3.2 mM/L), whereas the hydration trial was associated with a slight, insignificant metabolic acidotic effect (ABE decreased only 0.6 mM/L). The calculated free water ABE effect (change in sodium concentration) was offset by opposite changes in calculated chloride, lactate, phosphate, and albumin ABE effects.
