Liminal Entrepreneuring: The Creative Practices of Nascent Necessity Entrepreneurs

This paper contributes to creative entrepreneurship studies through exploring ‘liminal entrepreneuring’, i.e., the organization-creation entrepreneurial practices and narratives of individuals living in precarious conditions. Drawing on a processual approach to entrepreneurship and Turner’s liminality concept, we study the transition from un(der)employment to entrepreneurship of 50 nascent necessity entrepreneurs (NNEs) in Spain, the United Kingdom, and Ireland. The paper asks how these agents develop creative entrepreneuring practices in their efforts to overcome their condition of ‘necessity’. The analysis shows how, in their everyday liminal entrepreneuring, NNEs disassemble their identities and social positions, experiment with new relationships and alternative visions of themselves, and (re)connect with entrepreneuring ideas and practices in a new way, using imagination and organization-creation practices to reconstruct both self and context in the process. The results question and expand the notion of entrepreneuring in times of socio-economic stress.
Thermal and compositional structure of the subcontinental lithospheric mantle: Derivation from shear wave seismic tomography

Seismic tomography can provide unique information on the structure of the subcontinental lithospheric mantle (SCLM), but seismic velocity reflects both temperature and composition. We present a methodology for evaluating and isolating the relative contributions of these effects, which produces maps of regional geotherm and broad compositional constraints on the SCLM from the inversion of shear wave (Vs) seismic tomography. This approach uses model geotherms quantized in steps of 2.5 mW/m2 and three mantle compositions corresponding to typical Archean, Proterozoic, and Phanerozoic SCLM. Starting from an assumed composition for a volume of SCLM, lithospheric density at surface pressure and temperature is calculated for each geotherm at each point; the optimum geotherm is taken as the one yielding a density closest to the mean value derived from mantle xenoliths (3.31 g/cm3), since density varies with composition. Results requiring densities or geotherms outside the known natural range of these parameters worldwide require the choice of a different mantle composition. This technique, applied iteratively to a 275 km × 275 km Vs model developed by S. Grand (University of Texas, Austin), results in maps of the geotherm and regional density, which allow interpretation of SCLM composition within broad limits. These results can then be compared with local (paleo)geotherms and data for mantle composition, derived from xenolith suites. Application of this technique to the SCLM beneath Africa, Siberia, and North America shows good correlation with regional geological features, xenolith data, and other geophysical data.

Comparison of Direct and Video Assisted Views of the Larynx during Routine Intubation in Infants and Children

Purpose: Video assisted laryngoscopy has been rapidly incorporated into the anesthesiologist’s arsenal for challenging adult airway management. The development of pediatric video airway equipment presents an opportunity to expand upon the previous reliance on direct laryngoscopy alone. This study utilized the Storz DCI® Video Laryngoscope which consists of a standard straight 0 and 1 blade combined with a 2.8 mm fiberoptic light bundle built into the left side of the blade. Method: The ease of use, best direct and video-assisted glottic view was documented for 50 infants and children less than 2 years of age. Direct laryngoscopy was performed with the naked eye (direct view). The best views obtained with and without external laryngeal manipulation were graded by the laryngoscopist without looking at the video monitor. The views on the video monitor, located in front of the intubator and to the right of the patient, were simultaneously graded independently by another pediatric anesthesiologist. Results: Fifty infants and children, ages ranging from one day to 22 months, were enrolled in the study. There were 37 males, and 13 females. The average age was 10.5 months. ASA physical status ranged from I to III, with the vast majority of patients being either class I or II. The grade of laryngeal view on the video monitor was significantly improved when compared with that of direct laryngoscopy (p<0.05). Conclusion: In our study the view on the monitor screen was, on average, one grade better than the direct view. In only one instance was the view obtained with the video laryngoscope worse than that obtained under direct vision. The magnified view provided by the video laryngoscope allows for better visualization of airway structures in difficult airways and further help in facilitating securing the airway.
Does responsibility accounting in public universities matter?

Abstract Responsibility accounting is an administrative accounting method that measures the results of each responsibility centre. The concept of responsibility accounting is vested in costs and revenues performance. Managers are evaluated based on what is under their control. Hence, the purpose of this paper is to examine if responsibility accounting matters in Ugandan public universities. The paper adopted a cross-sectional survey that included both quantitative and qualitative approaches to find out if responsibility accounting matters. The qualitative data supplement quantitative data. The findings indicate that there is a system of responsibility accounting. Costs and revenues are managed at respective departments. Heads of department have authority to manage their budget-allocated estimates. They are responsible for their decisions against their budgets or votes. Costs and/or revenues are accumulated and reported upward from departments and faculties to university authorities. This study signifies that responsibility accounting follows hierarchical patterns in public universities.
Workplace Breathing Rates: Defining Anticipated Values and Ranges for Respirator Certification Testing

Abstract : Test methods currently used by the National Institute for Occupational Safety and Health (NIOSH) are designed to assure that respirators meet a minimum level of efficacy when tested under standard laboratory protocols. For air-purifying respirators (APRs), the primary performance tests most affected by airflow rate are filter gas-life capacity, particulate filter efficiency, and respirator breathing resistances. Presently, NIOSH measures all three parameters using constant-rate airflow conditions. An analysis of the measured and estimated minute volumes contained in the literature indicated a range from about 8 to 162 L min(exp -1) for unencumbered ventilation and work activities that spanned from mild to exhaustive. Based on an empirical relationship between minute volume and peak inspiratory flow (PIF), peak flows between 72 min(exp-1) and 183 L min (exp -1) would be expected for the mean minute volume for 38.5 L min(exp -1). The anticipated range of PIF rates for the 95th percentile minute volume is between 182 L min(exp -1) and 295 min(exp -1). The results of this literature review suggest an increases in cyclic flow rates used for respirator certification testing should be considered to better represent ventilation rates found in the workplace.
Moderating Effect of Earnings Management on the Relationship Between Corporate Social Responsibility Disclosure and Profitability of Banks in Indonesia

This study aims to obtain empirical evidence of earnings management (EM) as a moderating variable between corporate social responsibility (CSR) and profitability. This research was conducted by taking a sample of banking companies listed in the Indonesia Stock Exchange in 2010-2014. Data were collected using purposive sampling. The statistical method used was moderated regression analysis. Findings proved that CSR disclosure positively and significantly influences a company’s profitability. By contrast, eaarnings management had a negative and significant influence as the moderating variable on the relationship between CSR and a company’s profitability. These results suggested that a high level of EM, which leads to an enhanced CSR program, corresponds to weak profitability of the banking companies
Effect of rapid thermal annealing on performance of large area crystalline silicon position sensitive detector

In this paper we report on the effect of rapid thermal annealing (RTA) on the characteristics of diffused crystalline p-n Si one-dimensional (1-D) position sensitive detector (PSD). The Si-PSDs are made with planer technology using thermal diffusion technique for Si doping. The lateral voltage produced by irradiation of He-Ne laser on PSD was parallel to the plane of junction and dependence linearly on laser spot position. The PSD that treated with best RTA condition (850 °C/15s) exhibited higher position sensitivity (104μV/mm) as compared with that for untreated PSD (31μV/mm). Furthermore, the best PSD gave a non-linearity error of 1.46%. The performance improvement factors such as uniformity, linearity, and responsivity of annealed Si-PSDs are presented and analyzed.
ORGANIZATIONAL CULTURE AND ACADEMIC PERFORMANCE OF UNDERGRADUATE BUSINESS EDUCATION STUDENTS IN RIVERS STATE, NIGERIA

The purpose of this study was to investigate which the organizational culture could exert influence on the academic performance of undergraduate business education students in Rivers State, Nigeria with emphasis on caring, apathetic, exacting, integrative culture. This study adopted the co-relational research design, because the study attempted to establish relationship between the perceived organizational culture and students’ academic performance. The study was carried out in the Rivers State University of Science and Technology and Rivers State University of Education Eight hundred and sixty two (862) undergraduate business education students which was a representation of 30% of the target population participated in this study as respondents. Four rating scales in addition to students’ cumulative result scores were for data collection for this study. Mean and standard deviation scores were used to answer the four (4) research questions while Pearson’s Product Moment Correlation Coefficient (r) was used to test the four (4) hypotheses. The results of the study revealed high level of caring and integrative culture existing in the two universities with high level of academic performance and that significant relationship existed between the caring and integrative culture as aspects of the universities’ culture and their students’ academic performance. It was further revealed that no significant relationship existed between apathetic and exacting culture as aspects of the universities and their students’ academic performance. It was recommended that the universities authorities should ensure that conducive organizational culture be maintained within the university communities and also care for others, integrate and work together with the aim of achieving the objectives of the universities.
El uso de cama de pollo de buena calidad mejora la productividad de bovinos en crecimiento en engorda intensiva Using high quality poultry litter for growing beef cattle in an intensive feeding system increases animal performance

Ninetheen samples of poultry litter (PL) from 15 broiler farms were used to measure the variation of dry matter (DM), ash, organic matter (OM), acid detergent fiber (ADF), crude protein (CP), in vitro digestibility of DM and OM (IVDMD and IVOMD), indigestible CP in ADF (ICPADF), neutral detergent fiber (NDF) and hemicellulose. All the analysis were made by duplicated. Data in (%) were: DM 85.7 ± 5.5; ash 18.6 ± 2.6, OM 81.4 ± 2.6; CP 31.6 ± 2.3; IVDMD 76.1 ± 3.2; IVOMD 72.7 ± 3.6; ICPADF 3.2 ± 0.7; NDF 28.9 ± 5.7; hemicellulose 15.2 ± 4.0. These analysis showed a high variation among the different PL for all the measurements. The PL was included at three different levels (0, 15 and 30%) in order to evaluate the performance of 33 growing Holstein bulls (220 ± 36 kg initial weight). The trial lasted for 84 days. Eleven bulls were assigned to each diet in a completely randomized design including the initial body weight (BW) as covariable. Average daily gain (1.17, 1.27 y 1.17 kg/animal) and feed efficiency (6.00, 5.78 y 6.46) were not affected (P>0.05) by level of PL. Dry matter intake increased linearly (P<0.01) due to de PL level, increasing in 24 g/day for each percent unit of PL included in the diet. Likewise, DM feed intake was increased in 0.32 g/kg BW0.75. It is possible to use up to 30% of PL in the growing diets without reducing bull performance. Cost of gain was reduced in 18.4 % ( P<0.05) even when DM intake was increased with the PL.
Agenda-Setting, Priming, and Framing Revisited: Another Look at Cognitive Effects of Political Communication

Agenda-setting, priming, and framing research generally has been examined under the broad category of cognitive media effects. As a result, studies often either examine all 3 approaches in a single study or employ very similar research designs, paying little attention to conceptual differences or differences in the levels of analysis under which each approach is operating. In this article, I revisit agenda-setting, priming, and framing as distinctively different approaches to effects of political communication. Specifically, I argue against more recent attempts to subsume all 3 approaches under the broad concept of agenda-setting and for a more careful explication of the concepts and of their theoretical premises and roots in social psychology and political psychology. Consequently, it calls for a reformulation of relevant research questions and a systematic categorization of research on agenda-setting, priming, and framing. An analytic model is developed that should serve as a guideline for future research in these areas.
THE APPLICATION OF COGNITIVE DIAGNOSTIC MODELS TO DETERMINE THE NATURE OF DIFFERENCES BETWEEN MALE AND FEMALE STUDENTS IN MATHEMATICS OF THE FIRST HIGH SCHOOL GRADE

The causes and nature of differences between male and female students in learning mathematics has been interest of many scientists in education, but most of them have investigated mathematics as an overall constituent. In this study, the capabilities of CDM models are used for detailed examination of differences in the underlying math skills. Cognitive diagnostic measurement based on eight main attributes, consisting of 32 items, was run on a sample of 509 students, selected by a multi-stage cluster sampling among students of Tehran. Non-compensatory model of DINA showed differences in parameters of guess, slide, IDI, and RMSEA between the two groups. Male and female students had similar performance in the average dominance of math skills. However, female students were significantly more dominant than male students did in mathematical concepts (at alpha 0.01). In skills of Middle operations and the application of mathematics lessons, male students were significantly more dominant than female students did in real world problems (at alpha 0.05).
The Effect of Derivative Instrument Use on Capital Market Risk: Evidence from Banks in Emerging and Recently Developed Countries

This study investigates the use of derivative instruments by banks in both emerging and recently developed countries in terms of capital market risk. Overall, the results indicate that the use of options increases total return risk and unsystematic risk, while the use of forwards and futures decreases total return risk. Swaps, in the meantime, negatively affect systematic risk. The main conclusion is that banks in the sample do not appear to be at risk by using derivative instruments.
Generalizations of the Voronoi Diagram

Throughout many disciplines, the question of which objects lie with in another particular object's vicinity is of the upmost importance. The well-known 1st-order Voronoi diagram answers this question when a model can be represented in the Euclidean plane with objects as single points. As the phenomena that we model beco mes more co mplex, the notion of distance, bisectors, and space changes accordingly. It will be shown that the Voronoi diagram can be generalized to many problems by modifying the underlying mechanisms to be representative of the aforementioned notions.
Socioeconomic determinants of age at marriage in Malawi

Although age at first marriage has important demographic and health consequences for any population, no systematic analysis of changes in the timing of marriage has been conducted in Malawi. The purpose of this study is to identify factors affecting age at marriage among women in Malawi. This study used data obtained from 2000 and 2004 for Malawi Demographic and Health surveys. Univariate, bivariate and logistic regressions were employed to examine the relationship between age at marriage and selected background variables. Marriage in Malawi takes place early: nearly 70% of the respondents were married before the age of 18 years and the mean age at first marriage is 17.4 years. Age at marriage varies by age, region, rural-urban residence, religion, ethnicity and wealth. Early marriage and consequent early childbearing are related to high fertility, low status of women and adverse health risks for both the mother and child. The findings from logistics regressions indicate that age, region and education are the most important determinants of age at marriage in Malawi. The policy implications of the results are discussed. Key words: Age at marriage, socio-economic, determinants, Malawi.
THE QUALITY OF GOAT MEAT AND IT'S IMPACT ON HUMAN HEALTH

Today, goats are spread throughout the world. They live in small or large herds and in different areas and environments. Because of its distinctive taste and desired chemical composition, goat meat is increasingly consumed in Serbia. As animal foods, it is rich in protein, vitamins and minerals, but contains very little fat, especially cholesterol. The aim of this review paper is to highlight some health benefits, nutritional values and potential use of goat meat. On the chemical composition of goat meat affect race, gender, productivity and adaptability to stress, environment, management, diet, weight at slaughter and health condition as well as slaughter and procedures with the carcasses after slaughter. Average chemical composition of lean goat meat contains about 75.42% water, 3.55% fat, 19.95 % protein and 1.06% mineral matter. The energy value is about 580 kJ per 100 g. The goat meat has about the same nutritional value as well as sheep meat. Due to low content of saturated fatty acids and cholesterol, goat meat in the human diet is healthier alternative compared to other types of red meat. Polyunsaturated fatty acids prevalent in goatmeat, and the diet rich in unsaturated fatty acids is correlated with a reduced risk of stroke and coronary disease. In addition, in goat meat are present the essential amino acids such as lysine, threonine and tryptophan. Regardless to the nutritional value, goat meat is still less appreciated due to their specific smell and taste, the more if the animal is older. [Projekat Ministarstva nauke Republike Srbije, br.

Pranayama-an alternative supportive therapy against oxidative stress in essential hypertension

Background: Essential hypertension is one of the most prevalent diseases of the world. The underlying pathophysiological abnormalities that lead to the development of the elevated arterial pressure in this disorder remain elusive. Pranayam (yogic breathing exercises) techniques are beneficial in treating a range of stress related disorders such as hypertension and reducing signs of oxidative stress. The present study was undertaken to check effect of Pranayam on oxidative stress in cases of essential hypertension before and after Pranayam. Methods: Total 100 hypertensive subjects and 100 sex matched controls were enrolled in this study. Inclusion criteria include patients with blood pressure ≥ 140/90 mm of Hg, while patients with secondary hypertension, stroke, CAD, MI and diabetes mellitus were excluded. Serum PON-1 was estimated spectrophotometrically by Charlton Menys.V method. Serum SOD estimated spectrophotometrically by Mishra H.P. & Fridovich I,1972 method and Plasma MDA by colorimetric method of Satoch K.et al. We estimated PON-1, SOD and MDA in hypertensive and controls, then we suggested hypertensive for 3 months Pranayam, again the same parameters were measured and compared by using Students T test and one way ANOVA to determine significant differences. Results: Before Pranayam, PON-1 activity was decreased significantly (<0.001) in hypertensive subjects compared to controls. SOD was also decreased significantly (p<0.001) in hypertensives compared to controls and MDA was increased significantly (p<0.001) in hypertensives compared to controls, But after 3 months Pranayam, there was significant (p<0.001) improvement in PON-1 and SOD activity in hypertensives and significant (p<0.001) decrease in MDA levels in hypertensives compared to hypertensives before Pranayam. Conclusions: It is concluded that Pranayam can significantly reduce oxidative stress i.e. generation of free radicals, lipid peroxidation products (MDA) and significant increase in the level of antioxidant enzymes i.e. SOD & PON-1.MDA is a marker of oxidative stress. Pranayam not only reduces oxidative stress but also improves antioxidant status of the individual.
Side Lobe Reduction in an X-Band Horn Antenna Loaded by a Wire Medium

Through electromagnetic simulation, the present work reports on a comparative study of the enhanced radiation properties of a standard X-band horn antenna loaded by a wire medium. Acting as an artificial dielectric the wire medium consists of an array of parallel metallic wires installed into the antenna with the wires oriented in the direction of the incident electric field. As compared with the properties of the empty antenna, the wire-medium antenna produces appreciable reduction in the side-lobe levels with an improvement of 10 dB at 8.87 GHz in the first side lobe. For the wire-medium antenna, the E- and H-planes look similar, a property desired for precision radar and radiometric mapping systems.
