“If You Don’t Bring No Grits, Don’t Come”: Critiquing a Critique of Patrick Kelly, Golliwogs, And Camp as A Technique of Black Queer Expression
Authors: Barnes Sequoia
Published: February 2018

I have written this article in order to establish Patrick Kelly as a black forbearer of fashion. Kelly complicates our sense of fashion through his use of black memorabilia and camp to not only create something consumable but to comment on the black body as a consumable. Therefore, the role I play in acknowledging this black supernova, as Eric Darnell Pritchard calls him, is by critiquing Lewis and Fraley’s critique of Patrick Kelly and questioning why overtly expressing one’s queerness through camp has not been seen as a viable form of black expression in the mainstream narrative of black creativity. Lewis and Fraley’s complete dismissal of Kelly’s use of camp does not happen in a vacuum. Yet, I must remember that there is also the task of establishing a legacy of technique for Patrick Kelly. Who are his forbearers?

Published: February 2018

Background:

While there is some experimental evidence to support the use of cognitive forcing strategies to reduce diagnostic error in residents, the potential usability of such strategies in the clinical setting has not been explored. We sought to test the effect of a clinical reasoning tool on diagnostic accuracy and to obtain feedback on its usability and acceptability.

Methods:

We conducted a randomized behavioral experiment testing the effect of this tool on diagnostic accuracy on written cases among post-graduate 3 (PGY-3) residents at a single internal medical residency program in 2014. Residents completed written clinical cases in a proctored setting with and without prompts to use the tool. The tool encouraged reflection on concordant and discordant aspects of each case. We used random effects regression to assess the effect of the tool on diagnostic accuracy of the independent case sets, controlling for case complexity. We then conducted audiotaped structured focus group debriefing sessions and reviewed the tapes for facilitators and barriers to use of the tool.

Results:

Of 51 eligible PGY-3 residents, 34 (67%) participated in the study. The average diagnostic accuracy increased from 52% to 60% with the tool, a difference that just met the test for statistical significance in adjusted analyses (p=0.05). Residents reported that the tool was generally acceptable and understandable but did not recognize its utility for use with simple cases, suggesting the presence of overconfidence bias.

Conclusions:

A clinical reasoning tool improved residents’ diagnostic accuracy on written cases. Overconfidence bias is a potential barrier to its use in the clinical setting.

A Balanced Operation of Static VAR Compensator for Voltage Stability Improvement and Harmonic Minimization
Authors: Lomi Abraham , Dhadbanjan Thukaram
Published: February 2018

The conduction angles variation in operating a static var compensator can be used to meet the balanced and varying cyclic load of reactive power demand. However, this operation creates harmonics current into the system. An optimum combination of balanced reactive power from SVC and reactive power from the generator based on telephone influence factor (TIF), the total harmonic current factor (IT), and the distribution factor D is proposed. This approach is simulated to a typical distribution network. However, this operation creates harmonics currents into the AC system. This strategy is implemented to a conventional distribution network for various loading conditions is presented.
Study of the Effects of Ethanol As an Additive with a Blend of Poultry Litter Biodiesel and Alumina Nanoparticles on a Diesel Engine
Authors: Ramesha D. K. , Rajmalwar Nishad , Varma T. Sreeharsha , Mrithyunajaya Swamy K. M.
Published: February 2018

With the increasing population and rise in industrialization, the demand for petroleum reserves is increasing almost daily. This is causing depletion of the non-renewable energy resources. This work aims to find an alternative fuel for diesel engines. The use of poultry litter oil biodiesel obtained from poultry industry waste, which is a non-edible source for biodiesel, is very encouraging as an alternative fuel for diesel engines. The aim of this study is to observe and maximize the performance of poultry litter oil biodiesel by adding alumina nanoparticles and ethanol. The biodiesel is prepared with acid and the base catalysed transesterification of poultry litter oil with methanol using concentrated sulphuric acid and potassium hydroxide as catalysts. The experimentation is carried out on a CI engine with three different blends - B20 biodiesel blend, B20 biodiesel blend with 30 mg/L alumina nanoparticles, and B20 biodiesel blend with 30 mg/L alumina nanoparticles and 15 ml/L ethanol. The performance, combustion and emission characteristics of all three blends are compared with neat diesel. The results of the experiment show that ethanol as an additive improves the combustion and performance characteristics. It increases the brake thermal efficiency and peak cylinder pressure. It also reduces CO and UBHC emissions and there is a marginal increase in NOxemissions as compared to neat diesel.
Inhomogeneous GaInNAs quantum wells: their properties and utilization for improving of p-i-n and p-n junction photodetectors
Authors: Pucicki D.
Published: February 2018

A theoretical study of electronic structures and optical properties of GaInNAs/GaAs quantum wells has been performed. The inhomogeneous distributions of indium and nitrogen atoms along the growth direction were discussed as the main factors having significant impact on the QWs absorption efficiency. The study was performed by applying the band anticrossing model combined with the envelope function formalism and based on the material parameters which can be found in the literature. Indeed, the electronic band structure of 15 nm thick uniform Ga0.7In0.3N0.02As0.98/GaAs QW was computed together with electronic structures of several types of inhomogeneous QWs, with the same total content of In and N atoms. It was found that presented inhomogeneities lead to significant quantum wells potential modifications and thus to spatial separation of the electrons and holes wave functions. On the other hand, these changes have a significant impact on the absorption coefficient behavior. This influence has been studied on the basis of simulated photoreflectance spectra, which probe the absorption transitions between QW energy subbands. The electronic structure of inhomogeneous QWs under the influence of electric field has also been studied. Two different senses of electric field vector (of p-i-n and n-i-p junctions) have been considered and thus, the improvement of such types of QWs-photodetectors based on inhomogeneous GaInNAs QWs has been proposed.

Genetic parameters estimation in quantitative traits of a cross of triticale (x Triticosecale W.)
Authors: Ferrari Enzo David , Ferreira Víctor Aníbal , Grassi Ezequiel Martín , Picca Aurora María Teresita , Paccapelo Héctor Antonio
Published: February 2018

Triticale (x Triticosecale Wittmack) is a cereal used in Argentina as a winter seasonal pasture or feeding grain. Efforts made on breeding have led to varieties with potential grain yield similar or greater than with wheat. The aim of this study was to determine the gene effects, heritability, genetic gain, heterosis and inbreeding depression in various quantitative traits of a cross from contrasting lines of triticale using generation means analysis. The thousand kernel weight was adjusted to a model of additive-dominance, while the rest of the traits exhibited significant epistatic effects: additive x additive (i) for hectoliter weight, additive x dominance (j) for number grains per spike and grain yield per plant. Other traits showed a more complex as inheritance additive x additive (i) and additive x dominance (j) interactions effects for spike length or additive x dominance (j) and dominance x dominance (l) interactions effects for number of spikes per plant and number of spikelets per spike. High values of heritability and genetic gain were also detected for grain yield, spikelets per spike, spike per plant and hectoliter weight. All traits except spike per plant had positive relative mid-parent heterosis, but none resulted in positive heterobeltiosis, therefore this cross is not recommended for obtaining hybrids varieties. Selection in early generations by thousand kernel weight and hectoliter weight would be efficient, while the selection in advanced generations where segregation is minimal would be recommended for the remaining traits.

Values and Attitudes of Nordic Language Teachers Towards Second Language Education
Authors: von Post Christina , Wikström Patrik , Räihä Helge , Liubinienė Vilmantė
Published: February 2018

Issues in minority education in relation to citizenship have received more attention lately, because of new requirements for language testing in several countries (Bevelander, Fernandez & Hellström, 2011, p. 101). The acquisition of citizenship is more decisive for immigrant participation in society than the duration of stay in the country (Bevelander, Fernandez & Hellström, 2011). The second language is crucial for active citizenship and integration in this perspective. Most countries in the EU (except Ireland and Sweden) have language requirements for citizenship and the use of language testing becomes increasingly common among the countries that receive migrants. The rapid development highlights the need for new international studies on the relationship between citizenship and conditions for second language learning. The goal of the recent study is to compare premises, perspectives and scales of values of Danish, Norwegian and Swedish language educators, related to the requirements for immigrant citizenship. Previous studies (Björklund & Liubiniené, 2004) indicate that there are major differences in value systems even between the neighbouring countries. To reach the objective of the present study, interviews were conducted with language educators in Denmark, Norway and Sweden. The results have revealed two opposing patterns. The values of Swedish informants show a wide-ranging variation, while the Danish and Norwegian data on values are consistently similar. The results raise further questions about the effects caused by differences in values among language educators when comparing the countries and call for a further verification of the data in a more extended study, including Lithuania and other Baltic states.
Apprentissage du Français de la Douane dans le Cadre d’un Dispositif Hybride
Authors: Stasilo Miroslav
Published: February 2018

Sommaire

Les enseignants des langues étrangères utilisaient très longtemps des méthodes traditionnelles comme celle de grammaire-traduction. Le travail des professeurs et des andragogues est plus complexe aujourd’hui qu’auparavant. Les trois dernières décennies ont vu de nombreux changements : évolution technologique, pluridisciplinarité des sciences, globalisation. L’enseignement actuel des langues étrangères s’appuie sur des sciences aussi diverses que la linguistique, la psychologie, l’informatique, les sciences de communication en se basant sur le Cadre européen commun de référence pour les langues3 dont le but est l’identification et la définition des facettes théoriques de l’apprentissage d’une langue. Cet article analyse l’enseignement du français aux douaniers lituaniens en mettant l’accent sur des approches et des techniques actives, en particulier sur l’approche hybride. Il analyse les programmes proposés par le Centre de la formation des douaniers de Vilnius en se concentrant sur une étude plus détaillée du programme de l’apprentissage hybride en français pour lequel le français de spécialité est une priorité. Cette approche appliquée à l’enseignement des langues étrangères, se révèle séduisante pour les adultes car elle facilite l’intégration à la vie professionnelle. Elle participe également à la réalisation de la politique de multilinguisme grâce à la coopération entre les enseignants des langues étrangères et les apprenants. Plus que d’autres, elle favorise également les synergies interdisciplinaires grâce à l’utilisation des nouvelles technologies et des documents authentiques dans des domaines très variés : de la vérification douanière des véhicules aux questions d’éthique des douanes. Cet article présente enfin 5 composantes de l’acquisition lexicale qui accompagnent la formation professionnelle des douaniers en français : linguistique, discursive, référentielle, socioculturelle et stratégique.
Archaeology and anthropology: a growing divide?
Authors: Barnard Alan
Published: February 2018

The three volumes reviewed here have different origins but a common theme: all try to put some social or cultural anthropology into, or back into, archaeology. In the United Kingdom these are separate disciplines anyway, but in North America they are usually taught in the same department and have similar interests. The problem is that they are growing apart.

Mathematical model to assess the actual environmental risk from the point source emissions
Authors: Poltoratskaya V. N.
Published: February 2018

A mathematical model for point source emissions, which allows to determine the ecological risk, improve the ecological situation in the region with the ability to manage risk. Environmental risk is defined as the probability of exceeding a multidimensional integral field concentrations of pollutants its Maximum Admissible Concentration (with a small number of measurements) or frequency exceeding the given measured concentrations of pollutants its Maximum Admissible Concentration (with a large number of measurements). Components of air pollution regions, cities, enterprises are individual emission sources, so primarily developing assessment and environmental risk analysis should be performed for individual sources and, above all, to prevent significant risks – for the prognostic assessment of newly constructed or reconstructed enterprises, and for existing facilities – from the measurement data. For a single point source mathematical model includes: – raw data (results undertorch measurement characteristics of pollutants, sanitary protection and residential areas, the design parameters of the source and characteristics of the external environment for the worst-case); – forecast concentrations of pollutants depending on the design parameters of the source and characteristics of an environment for a source with circular and rectangular mouth, hot and cold emissions, extremely dangerous low wind speeds; – depending on the definition of the amendments to the measured concentrations due to the difference of the worst conditions from measurements; – depending on the definition given to the worst conditions of the measured concentrations and their statistical processing in order to obtain: a) the numerical characteristics of the density distribution of the concentration of pollutants emitted (mathematical expectations, standard deviations and correlation coefficients); b) environmental risk α, defined at a relatively small number of trials as a multidimensional probability integral of the density distribution of the concentrations obtained with the numerical characteristics, and a large number of tests - the frequency of the measured concentrations exceeding; c) environmental risks from air pollution αj separate pollutants; d) depending on the definition of the numerical characteristics of the forecast distribution density is not measured (secondary) concentrations of pollutants emitted to address their risks when determining α and αj. It is shown that, in accordance with applicable regulatory requirements must consider the risk of the negative impact of air pollution to humans, the level of which is determined using the values of the maximum one-time maximum allowable concentrations pollutants. Defined by experienced stochastic patterns of distribution of contaminants in the atmosphere.

World experience shows that the survey of green spaces by traditional methods is very time consuming, costly and does not always get all the information you need to make of adequate management decisions by municipal authorities. The aim of this article was to show the main stages of analysis and prospects of urban green space using aerial lidar data and submit the effect of three-dimensional visualization of the study area. There were presented the possibilities and perspectives of using the data obtained from airborne laser scanning (ALS) for the analysis of greenery on the example of Poremba district in Lublin (Poland). Research conducted in Poremba district in the Polish city of Lublin (district was built from 1988 to 2005 and is located in the western part of the city). Analysis of green space conducted using quantitative analytical methods. By detailed analysis of the study area were used aerial lidar data from the year 2015. To classify aerial lidar data such software were used: LP360, ArcMap 10.3, Toolbox LAStools. The process of analysis begins with the definition of points, belonging to ground (Ground - GR), and the classification was realized using «lasground» with tools LAStools. The article is dedicated to development the method of estimation the tree height based on airborne LiDAR data. Method applies more information about the three-dimensional structure of natural objects derived from the processing of airborne LiDAR data compared with known methods. Furthermore, the method is adapted to determine and calculate characteristics of stand which using for tree inventory in cities. Methodological and algorithmic instructions to determine the tree parameters in city were proposed. These instructions allow automatically calculating the characteristics of the tree parameters, such as the allocation of each tree and tree height. The study area was analyzed in terms of the distribution of vegetation (separately individual growing trees and groups of trees). For that purpose there was applied an available ALS data. Based on the ALS data there were separated the tops of the trees and their height. In order to verify the ALS data there were used the results of field measurements (coordinates for the tree trunks, the diameter at breast height of trees, their height, crown projection). The analysis of the greenery within the Poremba district using the ALS data after verification with the field measurements proved to be an effective tool for the characterization of the greenery areas in particular city. This research may be important in terms of planning the planting of greenery areas and spatial development of the Lublin.

Published: February 2018

The study concerned forecasts for the dynamics of beech (Fagus sylvatica L.) stands in the Polish Bieszczady and Ukrainian Beskydy with the use of FORKOME model іn different scenarios of climate changes. Simulation conducted in FORKOME model confirms that beech will exist in the Polish Bieszczady and Ukrainian Beskydy regions on the east boundary of beech areal. The changes in the Polish Bieszczady and Ukrainian Beskydy can be estimate as a positive for forest productivity and biomass accumulations. They were confirmed by fieldwork and events documented in the literature, which shows the reliability of the forecasts used FORKOME computer model. Work and study of this kind are necessary for rational forest management and to take appropriate development strategies.
Allozyme variation among european beech (Fagus sylvatica L.) stands in Bosnia and Herzegovina
Authors: Kvesić S. , Ballian D. , Parpan T. V.
Published: February 2018

From the economical and ecological point of view, beech (Fagus sylvatica L.) is one of the most important forest tree species in Bosnia and Herzegovina. To understand the significance of beech forests, something about the structure of forests and forest lands needs to be said. Bosnia and Herzegovina has 3.231.500 hectares of forests and forest land, which is about 60% of its surface. In the forest and forest lands structure, we can see that it has high forest occupying 51.1% of the forest area, coppice occupying 38.70%, shrubs occupying 4%, bare land and clearings occupying 5.80% and other unproductive areas occupying 0.40%. Beech can be found in mixed stands of beech and fir, as well as stands of beech, fir and spruce that occupy 46% of all high forests. Thus, the total area of ​​forests where the beech is found is approximately 1.652.400 hectares. The aim of the study was to carry out the analysis of genetic structures of natural beech populations in Bosnia and Herzegovina by using isoenzyme markers. Conducting a biochemical genetic structure analysis of 14 beech populations, using 10 enzyme systems with 16 isoenzyme gene loci, we found significant differences. Variability in some gene loci is large, while some populations for some gene loci showed monomorphism. The results indicate that in order to maintain natural genetic resources of common beech in Bosnia and Herzegovina, there should be a dense network of gene reserves established. This network from one of the Balkan countries should then become a constituent part of all-European network. These gene banks need in situ and ex situ methods (seed banks, seed stands, and seed orchards) to maintain the genetic diversity of populations. Based on the research results, every ecological niche of common beech i.e. their genetic variation should be conserved regarding the appropriate number of populations and individuals to preserve the ecological and physiological features of this valuable commercial species.
Factors related to decreased vitamin D levels in men with spinal cord injury living in a subtropical region
Authors: Bassuino Mauricio Sprenger , Kaminski Elisa Lettnin , Garcia Laís Oliveira , Linden Rafael , Antunes Marina Venzon , Schneider Rodolfo Herberto , Machado Denise Cantarelli
Published: February 2018

AIMS: To evaluate the levels of vitamin D, parathyroid hormone and calcium in individuals with spinal cord injury and to identify related factors.METHODS: A cross-sectional study included men with spinal cord injury, living in the South Region of Brazil. A questionnaire was applied to evaluate socioeconomic data, life habits and health. The time elapsed since the spinal cord injury was considered. Vitamin D was evaluated in plasma via liquid chromatography; calcium and PTH were measured in serum by a colorimetric method and electrochemiluminescence respectively. For data analysis, linear regression and chi-square test were utilized. Values of p<0.05 were considered significant.  RESULTS: The study included 39 paraplegic or tetraplegic men with spinal cord injury. The mean age was 35.52±9.78 years, and the mean time since injury was 6.09±5.55 years. The mean biochemical levels were: 19.0 ±6.98 ng/mL for vitamin D; 9.54±0.52 mg/dL for total calcium; and 34.81±10.84 pg/mL for parathyroid hormone. Individuals with sun exposure for more than two hours daily had higher vitamin D levels than those exposed up to one hour per day (p=0.001). Linear regression identified an inverse relationship between lesion time and vitamin D levels (regression coefficient: -0.424; p=0.029), while the other parameters did not show significant differences regarding the time elapsed since the lesion. Subjects with income above four minimum wages had higher vitamin D values (mean 25.67±5.45 ng/mL) when compared to those with income up to four minimum wages (mean 18.43±6.79 ng/mL) (p=0.021). CONCLUSIONS: Levels of vitamin D were inversely correlated to the time elapsed since the spinal cord injury, probably due to insufficient sun exposure resulting from prolonged limitation of mobility. In addition, lower levels of vitamin D were associated to lower income. These factors may aggravate bone loss associated with decreased mobility resulting from spinal cord injury.
Ten myths about work addiction
Authors: Griffiths Mark D. , Demetrovics Zsolt , Atroszko Paweł A.
Published: February 2018

Background and aims

Research into work addiction has steadily grown over the past decade. However, the literature is far from unified and there has been much debate on many different issues.

Aim and methods

This paper comprises a narrative review and focuses on 10 myths about work addiction that have permeated the psychological literature and beyond. The 10 myths examined are (a) work addiction is a new behavioral addiction, (b) work addiction is similar to other behavioral addictions, (c) there are only psychosocial consequences of work addiction, (d) work addiction and workaholism are the same thing, (e) work addiction exclusively occurs as a consequence of individual personality factors, (f) work addiction only occurs in adulthood, (g) some types of work addiction are positive, (h) work addiction is a transient behavioral pattern related to situational factors, (i) work addiction is a function of the time spent engaging in work, and (j) work addiction is an example of overpathogizing everyday behavior and it will never be classed as a mental disorder in the DSM.

Results

Using the empirical literature to date, it is demonstrated that there is evidence to counter each of the 10 myths.

Conclusion

It appears that the field is far from unified and that there are different theoretical constructs underpinning different strands of research.

Aim. To confirm the data available in the literature on the cardiac safety of antidepressants. Subjects and methods. The archival data of 146 case histories were retrospectively analyzed. A study sample consisted of 96 cardiac inpatients regularly taking an antidepressant for more than 3 days during treatment for the underlying cardiovascular disease. The safe use of antidepressants was evaluated in terms of initial electrocardiogram (ECG) QTc interval changes, systolic and diastolic blood pressures (BP) (SBP and DBP), heart rate (HR), and hemorrhagic complications. The data obtained over periods of 3- and 6-8 days were analyzed. Results. The sample showed no clinically significant ECG QTc interval changes when taking regularly antidepressants within 8 days. Analysis of the dynamics of BP and HR in patients receiving antidepressants revealed no statistically significant differences in these indicators before and 3 and 6-8 days after drug administration. No case of hemorrhagic complications was seen in the study group taking antidepressants. Conclusion. The investigation generally confirms the high cardiac safety of new-generation antidepressants within at least the first week of therapy. Noteworthy are the low daily drug dosages (relatively specified in the instructions) that are sufficient for most cardiac patients with depressive disorders and an additional factor for minimizing adverse reactions.
Estimation of extreme inter-day changes to peak electricity demand using Markov chain analysis: A comparative analysis with extreme value theory
Authors: Sigauke Caston , Chikobvu Delson
Published: February 2018

Uncertainty in electricity demand is caused by many factors. Large changes are usually attributed to extreme weather conditions and the general random usage of electricity by consumers. More understanding requires a detailed analysis using a stochastic process approach. This paper presents a Markov chain analysis to determine stationary distributions (steady state probabilities) of large daily changes in peak electricity demand. Such large changes pose challenges to system operators in the scheduling and dispatching of electrical energy to consumers. The analysis used on South African daily peak electricity demand data from 2000 to 2011 and on a simple two-state discrete-time Markov chain modelling framework was adopted to estimate steady-state probabilities of two states: positive inter-day changes (increases) and negative inter-day changes (decreases). This was extended to a three-state Markov chain by distinguishing small positive changes and extreme large positive changes. For the negative changes, a decrease state was defined. Empirical results showed that the steady state probability for an increase was 0.4022 for the two-state problem, giving a return period of 2.5 days. For the three state problem, the steady state probability of an extreme increase was 0.0234 with a return period of 43 days, giving approximately nine days in a year that experience extreme inter-day increases in electricity demand. Such an analysis was found to be important for planning, load shifting, load flow analysis and scheduling of electricity, particularly during peak periods.

ELISA Protocol v1
Authors: Xia Cj
Published: February 2018

ELISA (enzyme-linked immunosorbent assay) is a plate-based assay technique designed for detectingand quantifying peptides, proteins, antibodies, and hormones. In an ELISA, an antigen must beimmobilized to a solid surface and then complexed with an antibody that is linked to an enzyme.Detection is accomplished by assessing the conjugated enzyme activity via incubation with a substrateto produce a measurable product. The most crucial element of the detection strategy is a highlyspecific antibody-antigen interaction. This protocol describes the steps for performing sandwich ELISA.
“Approaching an Abyss”: Liberalist Ideology in a Norwegian Cold War Business Paper
Authors: Fonn Birgitte Kjos
Published: February 2018

The international business press has been a powerful and influential voice in modern societies and, as its formative years took place during the Cold War, a closer look at the ideologies that were promoted in this part of the press is of interest. Until the 1970s, Farmand was the only Norwegian business magazine of any size and standing. Trygve J. B. Hoff, Farmand’s editor from 1935, was part of the Mont Pèlerin Society (MPS), a neoliberal intellectual collective established in 1947 with participants such as Friedrich Hayek and Ludwig von Mises. This article is a study of the ideas that Hoff promoted, particularly in Farmand, from the 1940s to the 1970s.

Authors: SOLODILOV Mikhail V. , KOROBOVA Ekaterina S.
Published: February 2018

The article describes the background of the principle of architecture and monumental arts synthesis that emerged in the domestic version of modernism in 1960s. It mentions artists and architects who contributed to the modernist architecture enrichment with artistic and plastic tools. The infl uence of Moscow monumentalists who worked all over the USSR improving the image of young Soviet cities is stressed. With Toglyatt i as an example, the paper demonstrates diff erent ways how the principle of architecture and monumental arts synthesis might be applied and also discusses the principle of a single urban design plan that emerged in Soviet architecture. The authors describe construction objects built according to this principle, give glimpses of biographies of artists. The given details are based on the previous archive studies. They also provide possible reasons for the decline in monumental art and predict the emergence of modern forms of art that would interact with architecture. Objects, to which the principle of architecture and monumental arts synthesis might be applied, become a potential and an internal resource for tourist and cultural att raction of the city.
