A joint analysis of country and industry factors in European stock and corporate bond returns

In this thesis I provide a joint analysis of the relative importance of country and industry factors in European stock and corporate bond returns for the period April 1999 to January 2013. Using a unique data set of stock and corporate bonds that are linked at the firm level, I find that stock returns are mainly driven by industry factors, while country factors dominate industry factors in corporate bond returns. However, after the start of the global financial crisis, country factors appear to become at least as important as industry factors in stock returns, while the relative significance of country factors in corporate bond returns seems to lower due to a rising importance of industry factors. Moreover, my findings show that both country and industry factors should be included in a stock diversification strategy to obtain optimal performance in terms of mean-variance efficiency. In contrast, a diversification strategy across countries only already appears to be mean-variance efficient for corporate bonds.
HOW MANY RATIONAL POINTS DOES A RANDOM CURVE HAVE?

A large part of modern arithmetic geometry is dedicated to or motivated by the study of rational points on varieties. For an elliptic curve over Q, the set of rational points forms a finitely generated abelian group. The ranks of these groups, when ranging over all elliptic curves, are conjectured to be evenly distributed between rank 0 and rank 1, with higher ranks being negligible. We will describe these conjectures and discuss some results on bounds for average rank, highlighting recent work of Bhargava and Shankar.
The Mediator Role of Learning Strategies in the Relationship between Academic Self-Efficacy and Test Anxiety

The purpose of this study was to determine the mediator role of learning strategies in the relationship between academic self-efficacy and test anxiety. This research was done in a descriptive-correlational manner. The sample of study consisted of 350 public high school students from four high schools in Kerman selected through random multistage cluster sampling method. To gather the data, the academic self-efficacy Scale (Jinks Morgan, 1999), learning strategies scale (Kember & et al., 2004), and the test anxiety scale (Friedman-Jacob, 1997) were used. Path analysis results showed that Academic self-efficacy had both direct (=−.20), and indirect effects, mediated by Deep and Surface strategies (=−.08). Deep learning strategy was the strongest predictor, with a direct effect value of 0.32. The explanatory power of the predictors on test anxiety was medium (R2= 0.36). Considering the results, the learning strategies (deep) and academic self-efficacy had a significant effect on students' test anxiety. Therefore, strengthening of this individual feature in students can lead to the better performance of students in the exam situation by decreasing test anxiety.
Opportunities lost The Impact of the russian Embargo on its Agri-Food Trade with the EU : Analysis by Selected Indicators 1

The export of agri-food products from the European Union (EU) to Russia has been negatively influenced by the Russian embargo. The objective of this paper is to analyze the impact of the Russian agri-food embargo on EU agri-food exports to Russia from 2010 to 2016 and to consider the possibility of avoiding the embargo using Belarus as a re-exporting country. The revealed comparative advantage (RCA) index was used to assess the impact of Russian sanctions on agricultural exports from the EU to Russia. The main consequence of the embargo was a significant decline in EU agri-food exports to Russia. European producers responded by trying to increase the territorial diversification of their customers. In the beginning, they tried to keep the Russian market through re-export operations, which is evident in the example of Belarus. Calculation of RCI points to the fact that mutual agri-food trade has changed significantly. Prior to the embargo, agri-food exports from the EU to Russia were competitive, but these advantages have been lost. In 2010, Russia was the second most important agri-food market for the EU. However, as a consequence of the embargo, it dropped to fifth place in 2016. The paper also assesses the future development of agri-food trade between the EU and Russia based on a linear model.
Corporate Divestment Decision Factors : A Systematic Review

I study the underlying decision factors of corporate business entity divestments. Specifically, I address four questions. Firstly, what are decision factors concerning the business entity (divestment object) itself that influence divestment? I conclude from previous research that negative entity performance, insufficient benefits from the interplay between entities (whether between related or unrelated entities) and entity inferiority to marketplace alternatives (whether concerning costs or market opportunities) each considerably increases business entity divestment likelihood. Secondly, what are the psychological factors within decision-makers that influence divestment? I show from previous research that decision-makers’ familiarity with the entity’s business segment may distort a decision-maker’s entity assessment, thus biasing divestment decisions; escalation of commitment may lead to retaining failing projects despite being aware of their poor performance; and the managerial incentive to conceal investment mistakes may at least postpone divestment as a result of self-interests. Thirdly, what factors in the organizational context influence divestment? I find from previous research that negative firm performance and path dependence of preceding divestments increase general propensity to divest, whereas units that are perceived to be essential to organizational image and identity are more reluctantly exited. Fourthly, which external stakeholders are important influencing factors in divestment? I indicate from previous research that the media, political entities, and blockholders may pressure decision-makers significantly and sway divestment decisions.

Natural Parasitization of Maruca vitrata (Geyer) by Bracon hebetor

Spotted pod borer, Maruca vitrata (Pyralidae : Lepidoptera) is a major insect pest that attacks the reproductive parts of grain legumes including pigeonpea and cowpea, thus drastically reduces the yield. During November 2008, a survey was conducted at New Research Farm of IIPR to know the natural enemies associated with M. vitrata in short duration pigeonpea. Among the 143 larvae of various instars, 6 late instar larvae were parasitised by Bracon (Habrobracon) hebetor. This ectoparasitoid formed 5 to 9 cocoons per larvae of M. vitrata and the total life-cycle was completed within 8 Parasitized Maruca larva
Study Effects of Resveratrol, Cuminumcyminum, Essence and Vitamin C on Blood Sugar, Lipid, Insulin Resistance and Advanced Glycatedend Product (AGEs) in Type2 Diabetic Patients

Introduction: Advanced glycated end products (AGEs) play an important role in the progression of diabetes and exacerbation of its complications. The aim of this study was to investigate the effects of supplementation of Resveratrol, the essential oil of cumin and Vitamin C, on levels of blood sugar, lipid, insulin resistance and AGEs in type 2 diabetic patients. Materials and Methods: In this double-blind randomized clinical trial, diabetic patients were randomly divided into four groups: Cumin essential oil, Resveratrol supplement, vitamin C and the control group. After two months, Insulin resistance, AGEs, Insulin, glucose and lipids were measured, using standard kits and results were analyzed. Results: There were no significant differences between the groups in the beginning of the study. Insulin resistance and AGEs showed no significant differences between the four groups after study, although in the Resveratrol group, levels of body mass index (BMI) and glycosylated hemoglobin (HbA1C) were reduced (p=0.001, p=0.04). In the cumin group, BMI (p=0.001), triglyceride (p=0.01) and HbA1C (p=0.01) levels decreased significantly after intervention. In the vitamin C and control groups, none of the measured variables were significantly different post-intervention. Conclusion: Resveratrol can be effective in weight loss and metabolic control in diabetic patients. Cumin showed high efficacy in the improvement of sugar and dyslipidemia indices in these patients.

PLANT PROTECTION PRODUCTS VERSUS CHANGES IN THE NATURAL ENVIRONMENT AND THEIR IMPACT ON THE HUMAN HEALTH

Farmers wanting to meet the global competition increasingly often use chemical agents to increase yields. However, more and more research confirms the assumptions of scientists on the negative impact of pesticides on life forms. Research points to a significant statistical linkage between the use of plant protection products and higher risk of developmental disorders, neurological disorders and certain forms of cancer. These disorders might be transferred to the next generations through changes in the gene expression, which are not connected to changes in the DNA sequence. The paper is to present the risks for the natural environment following from the use of pesticides in agriculture, which is also linked to human health.

An Efficient Method to Study Shielding Effectiveness of Rectangular Enclosure with Wire Penetration

─ This paper presents a reliable and efficient analytical model to calculate the shielding effectiveness (SE) of a rectangular enclosure with wire penetration under plane wave illumination over frequency range of 0 to 2.5GHz. The wire is equivalent to monopole antenna, and the four-element lumped-parameter equivalent circuit for monopole antenna is established to represent the coupling process between electric field and the wire. Based on dynamic Green function, the approximate solution of the electric field distribution in the enclosure excited by the internal wire is derived, and Bethe's theory is used to calculate the approximate solution of the electric field distribution in the enclosure excited by the aperture when the aperture size is not negligible. Several cases are presented to verify the validity of the model. The effects of the length of the wire inside and outside the enclosure, wire penetration and observation point position as well as incident direction of plane wave on the SE are discussed in detail. Simulation result of the proposed model are in good agreement with that of the transmission line matrix (TLM) method. Index Terms ─ Equivalent dipole, rectangular enclosure, shielding effectiveness, wire penetration.
SOCIO-ECONOMIC DETERMINANTS OF BIRTH AND EMERGENCY PREPAREDNESS IN ANTENATAL CARE: A STUDY AMONG MOTHERS IN THE WA MUNICIPALITY *Yelkumo,

Inadequate birth and emergency preparedness are a recipe for the development of complications that often lead to morbidities and mortalities during pregnancy and child birth. Yet, little is known of the socio-economic factors that affect birth and emergency preparedness in the Wa Municipality. Therefore, the objective of the study was to assess the socio-economic determinants of birth and emergency preparedness among mothers with children up to one year of age. A facility based cross sectional study was employed to get information from respondents. The sampling technique used was multistage sampling and a structured questionnaire was used as the data collection instrument. Logistic regression was used to identify the determinants of birth and emergency preparedness. A total of 401 mothers participated in the study. It was revealed that 43.4% of respondents were knowledgeable in pregnancy danger signs. About 62% were adequately prepared for birth. In multivariate analysis, mothers who: had attained at least secondary education (P< 0.001), had high wealth index (P< 0.001), had at most 2 children (P=0.035), had four or more ANC visits (P=0.003) were significantly more likely to prepare adequately for birth. The above variables stood out as the major socio-economic determinants of birth and emergency preparedness. The study showed that birth and emergency preparedness among mothers in the study setting occurs in the context of specific socio-economic factors that are likely to mould the behaviours of women towards preparing adequately for birth preparedness and emergency services uptake. There is therefore the need for all stakeholders in the area of health to work towards reinforcing these variables or determinants to ensure women are adequately prepared for birth and emergencies.
The Education Column

Logo’s history dates back more than half a century; time enough for several hundred environments to be developed which all rely on Papert’s famous philosophy of learning. This article presents a selection of Logo environments that shaped the domain of novice programming. Quite contrary to the belief that Logo has gone extinct [19], this old language is currently experiencing a new upswing with a growing number of students who make their very first steps into the world of programming. At the end of our historic overview, we present a contemporary Logo environment that is used by tens of thousands of students every year and with which the old Logo legacy lives on even today.
Implications of restricted access to grazing by cattle in wet season in the Sahel

To address the problem of restricted access to grazing by cattle in wet season in the Sahel, a grazing trial was conducted to study the effect of duration of grazing and grazing method on cattle nutrition and performance. Twenty-four intact steers weighing 259 kg (SD 1⁄4 62) were randomly allotted to four treatments to study the effect of the combination of grazing method (tethering and close herding) and grazing duration (6 and 9 h per day) on diet selection, faecal output, forage intake, grazing behaviour and weight changes in the wet season. Three esophageally fistulated steers were used in a cross-over design to sample diet selected by tethered and herded animals. Extrusa samples from esophageally fistulated steers and faecal output from intact steers were collected in weeks 6 and 9 of the experiment and grazing behaviour of the intact steers was observed in week 6. Tethered animals selected diets of lower organic matter digestibility (OMD) but tethering had no significant effect on crude protein. Close herded steers consistently consumed more forage than those tethered in both periods. Both grazing method and duration had significant effect on ingestion rate by the steers. Tethered steers had lower average daily gain than those herded. The results demonstrate that the common practice of tethering sedentary cattle in the wet season in the southern Sahel in West Africa reduces forage intake and consequently average daily gain. r 2007 Elsevier Ltd.

Music to whose ears? The effect of social norms on young people’s risk perceptions of hearing damage resulting from their music listening behaviour. Abbreviations: PSP - Personal stereo player NIHL - Noise induced hearing loss

Professional and community concerns about the potentially dangerous noise levels for common leisure activities has led to increased interest on providing hearing health information to participants. However, noise reduction programmes aimed at leisure activities (such as music listening), face a unique difficulty. The noise source that is earmarked for reduction by hearing health professionals is often the same one which is viewed as pleasurable by participants. Furthermore, these activities often exist within a social setting, with additional peer influences which may influence behaviour. The current study aimed to gain a better understanding of social-based factors that may influence an individual’s motivation to engage in positive hearing health behaviours. 484 participants completed questionnaires examining their perceptions of the hearing risk associated with music listening, and asking for estimates of their own and their peer’s music listening behaviours. Participants were generally aware of the potential risk posed by listening to personal stereo players (PSPs) and the volumes likely to be most dangerous. Approximately one in five participants reporting using listening volumes at levels perceived to be dangerous, an incidence rate in keeping with other studies measuring actual PSP use. However, participants showed less awareness of peers’ behaviour, consistently overestimating the volumes at which they believed their friends listened. Misperceptions of social norms relating to listening behaviour may decrease individuals’ perceptions of susceptibility to hearing damage. The consequences for hearing health promotion are discussed, along with suggestions relating to the development of new programs.
PERFORMANCE ANALYSIS AND PROBABILITIES BY GENDER IN JUDO : COMBAT PHASES , TECHNIQUES AND BIOMECHANICAL LEVERS UDC 796 . 853 . 23 : 015

The aim of the current study was to compare and verify factors associated with gender in combat phases, techniques and biomechanical leversused during judo matches, and performance probabilities in those same matches. We evaluated highlevel judo athletes from each weight division who qualified for the Olympic Games. 773 male and 638 female bouts were analyzed based on the motor actions during approach, gripping, attack, defense, groundwork and biomechanics of techniques. The current results demonstrated significant differences between male and female bouts in pause frequencies [7(4;12); 9(4;13); p≤0.05], and approach with displacements [1(0; 6); 3(0;9); p≤0.05]. Female athletes used higher frequencies of techniques with different biomechanical levers for attacks (i.e. trunk leg lever attempts; waist lever variable attempts, waist lever variable effective and attempts, and maleolo lever effective and attempts; p≤0.05), while men used more variations of gripping (i.e. left collar, left collar and sleeve, both collars, right sleeve, left sleeve and both sleeves; p≤0.05) and groundwork attacks (i.e. Osae-waza, kansetsu-waza and shime-waza attempts; p≤0.05). The regression analysis demonstrated that female performance probabilities are associated positively with the use of Osae-waza, Variable/medium length attempted and scored, Arm/foot lever, Minimum lever attempted and scored and negatively with the grip on both collars, while male performance probabilities are associated positively with the use of Variable/medium length scored, Arm/foot lever scored, Minimum lever attempted and negatively with the grip on the right sleeve.
