Stress, coping strategies and social support amongst grade 11 students in historically disadvantaged schools

Adolescence can be viewed as a crucial part of the continuous life cycle. Coping plays an important factor which prepares the individual for the future, where he or she will have many new experiences and responsibilities thrust upon him or her. The aim of this research was to investigate the stress level, coping strategies and social support among grade11 students. The rationale of the study was that every year adolescence grapples with the issue pertaining to stress and it requires research as to how adolescence cope with their lives. Richard Lazarus’ stress and coping model was used as the theoretical framework. This was a quantitative research study where questionnaires were distributed among 210 grade 11 students. The Adolescent Perceived Events Scale (APES) was used to measure stress and the mean scores indicated that females (33.98) scored slightly higher than the males (31.72). This could be due to females responding to certain events differently. However, there was no significant difference found between the stress levels of males and females. The Ways of Coping Questionnaire (WCQ) measured coping strategies and the findings indicated that the mean scores of social support (17.57) are slightly higher than the characteristics of depression (17.38). The correlation coefficient of -0.51 can be interpreted as a slight-almost negligible relationship. The direction of the relationship is negative which can be interpreted as the higher the social support level, the lower scores on depression. The Perceived Social Support Scale (PSS) consisting of the Perceived Support from friends subscale (PSS-Fr) and the Perceived Support from family subscale (PSS-Fa) was used to measure social support. The mean scores indicated that the females obtained a slightly higher score (17.68) than the males (17.33) but there was no significant difference found between the level of social support of males and females. The scores indicated that females and males have more or less the same amount of social support. Recommendations were made as to address the issue of response-bias, information may be elicited by means of parents being more involve in the young person’s life through being educated in identifying the signs that their child is not coping and assisting them to deal with daily stressors through attending workshops. Schools/teachers can assist parents with these workshops where both the parent and child can attend. Schools/teachers can also make provision to educate the young person through having a life skills period where specific focus can be on study skills, nutritional and healthy eating habits, exercises. An intervention program can also be implemented and form part of the curriculum.
heoretical study of flashing and water hammer in a supercritical water cycle uring pressure drop

During a loss of coolant accident (LOCA) the pressure of the coolant can drop significantly in the vicinity of the leak. It will be shown that unlike in pressurized water reactors (PWRs) where this pressure drop can cause only sudden vaporization – also called flashing – in supercritical water cooled reactors (SCWRs) it can cause sudden condensation (condensation-induced water hammer), too. The reason is that from supercritical state the system can go to metastable liquid as well as to metastable vapour state after LOCA. Relaxation from metastable fluid states is a fast process, followed by a local positive or negative pressurejump, which might increase the damage around the leak. Conservative estimation will be given for the magnitude of these pressure jumps caused by the flashing or water hammer by assuming various initial pressure losses. In our calculations, three different equations of state are used: the simple van der Waals EoS; the Redlich–Kwong as an empirical development; and the more sophisticated non-cubic Deiters equation of state. These equations are able to describe metastable states qualitatively but with different accuracy. These calculations can help us to map the local immediate effect of any sudden pressure drop to de and therefore it can help
Rheological Study in Steady State 3 . 1 . Speed Profile for a Newtonian Fluid in a Cylindrical Couette

Polyethylene oxide solutions have a behavioral flexibility that provides researchers with the opportunity to use constitutive law models in a variety of ways for their MRI characterization. Our results obtained in numerical simulation carried out in 2D and 3D for speed profiles of a solution of PEO deployed by the simple method of the cylindrical Couette geometry considering the fluid Newtonian defect, allowed to identify the behavior of fluid complex (rheo-fluidifying threshold fluid). The relevance and the interest of the method are examined by analyzing these results generated by the numerical data obtained, since these profiles depend on the non-Newtonian properties of the fluid which one does not know a priori and which one seeks to measure by postulating first to the power law of Ostwald, then to the truncated power law.
Biochemical characteristics imparting resistance against Alternaria blight in cauliflower genotypes

Alternaria blight disease has been reported from all the continents of the world, affects most of the cruciferous crops. Alternaria blight incited by foliar pathogen, Alternaria brassicae has become a major constraint in the successful cultivation of this crop. Development of resistant varieties is the most appropriate approach to control the disease and the concept is now developing to explore the built-in plant defense mechanism in relation to pathogen attack. In the present study, an attempt was made to identify biochemical characteristics imparting resistance against Alternaria blight in cauliflower genotypes. The moderately resistant genotypes had higher total chlorophyll, total phenols, total soluble sugars, total proteins, flavonoids and ascorbic acid than the susceptible genotypes. The chlorophyll content was found to be lesser in the infected leaves than the healthy ones. The reduction in total phenols, total soluble sugars, total proteins, flavonoids and ascorbic acid was at a higher rate in susceptible ones than the moderately resistant genotypes. These biochemical characteristics might be responsible for imparting resistance against Alternaria blight in cauliflower genotypes.
The Massive Stellar Population of W49: A Spectroscopic Survey

Massive stars form on different scales ranging from large, dispersed OB associations to compact, dense starburst clusters. The complex structure of regions of massive star formation, and the involved short timescales provide a challenge for our understanding of their birth and early evolution. As one of the most massive and luminous star-forming region in our Galaxy, W49 is the ideal place to study the formation of the most massive stars. By classifying the massive young stars deeply embedded into the molecular cloud of W49, we aim to investigate and trace the star formation history of this region. We analyse near-infrared $K$-band spectroscopic observations of W49 from LBT/LUCI combined with $JHK$ images obtained with NTT/SOFI and LBT/LUCI. Based on $JHK$-band photometry and K-band spectroscopy the massive stars are placed in a Hertzsprung Russell diagram. By comparison with evolutionary models, their age and hence the star formation history of W49 can be investigated. Fourteen O type stars as well as two young stellar objects (YSOs) are identified by our spectroscopic survey. Eleven O-stars are main sequence stars with subtypes ranging from O3 to O9.5, with masses ranging from $\sim 20$ $M_{\odot}$ to $\sim 120$ $M_{\odot}$. Three of the O-stars show strong wind features, and are considered to be Of-type supergiants with masses beyond 100 $M_{\odot}$ . The two YSOs show CO emission, indicative for the presence of circumstellar disks in the central region of the massive cluster. The age of the cluster is estimated as $\sim1.5$ Myr, with star formation still ongoing in different parts of the region. The ionising photons from the central massive stars have not yet cleared the molecular cocoon surrounding the cluster. W49 is comparable to extragalactic star-forming regions and provides us with an unique possibility to study a starburst in detail.
nderstanding transnational political involvement among enegalese migrants : The role of acculturation preferences nd perceived discrimination

In political debates, migrants’ political involvement in their countries of origin and successful adaptation to receiving countries are often portrayed as incompatible. We address this concern by examining the links between acculturation preferences, perceived discrimination, and migrants’ transnational political involvement in their country of origin. In line with collective action research, a cross-sectional questionnaire study (N = 84) among Senegalese migrants in Paris (France) and Geneva (Switzerland) examined three pathways to transnational political involvement (motivations and actual behaviour). Perceived discrimination, the grievances pathway, was positively related to both transnational motivations (but only when desire to adopt the receiving culture was low) and political behaviour in Senegal. Desire to adopt the culture of the receiving society as an acculturation preference, the embeddedness pathway, was also positively linked to transnational motivations and political behaviour. Finally, desire to maintain the culture of origin as an acculturation preference—the collective identification pathway—was unrelated to transnational political involvement. These findings underscore the compatibility of transnational political involvement in countries of origin and adaptation to receiving societies. We discuss the pivotal role of political psychology in bringing together acculturation psychology and transnationalism studies. © 2014 Elsevier Ltd. All rights reserved.
Cellulose degradation capabilities of dung beetle, Euoniticellus intermedius, larva gut consortia

This study assessed the capabilities of the dung beetle, Euoniticellus intermedius (Coleoptera: Scarabaeida), larva gut consortia in degrading cellulose that can serve as glucose source for biofuels production. A total of 144 live dung beetles were randomly collected from a dairy farm and bred in a temperature controlled insect rearing room. On reaching the late second to third instar stage, dung beetle larvae were harvested, dissected and the gut micro-flora were cultured in medium containing cellulose as sole carbon source. Microbial growth (total protein concentration) and cellulose degradation activity (reducing sugars concentration) in the cellulose cultures were monitored successively for 15 days. Statistical analysis showed that there was significant microbial growth, but no significant increase in reducing sugar levels. Despite the lack of increase in reducing sugar levels, it was concluded that the dung beetle larva gut has micro-flora with cellulose degrading capabilities that allowed it to grow and survive in the cellulose minimal medium. Key words: Dung beetle, Euoniticellus intermedius, cellulose, biofuels.
An inexhaustive criticism of the standard economic theory from an Austrian perspective related to growth and development

The main purpose of this paper is to underline the downfalls of neoclassical growth theory. The narrow and artificial framework given by the neoclassical economists have no correspondent in real life. With a 'refreshed breath' the Austrian School of Economics tried to explain the dynamic and competitive market process in a constantly changing world. Aspects like time in the decision- making process, imperfect knowledge and the nature of market coordination to the changing circumstances are just some of the many key notions which offered us a different perspective over reality. The ideational contact with the brightest minds which Austrian School of Economics provided, allows us to perceive in a different light the neoclassical judgments.
Suppression of magnetism in Ba 5 AlIr 2 O 11 : Interplay of Hund's coupling, molecular orbitals, and spin-orbit interaction

The electronic and magnetic properties of ${\mathrm{Ba}}_{5}{\mathrm{AlIr}}_{2}{\mathrm{O}}_{11}$ containing Ir-Ir dimers are investigated using the generalized gradient approximation (GGA) and GGA + spin-orbit coupling (SOC) calculations. We found that the strong suppression of the magnetic moment in this compound recently found by Terzic et al. [Phys. Rev. B 91, 235147 (2015)] is not due to charge ordering but is related to the joint effect of the spin-orbit interaction and strong covalency, resulting in the formation of metal-metal bonds. They conspire and act against the intraatomic Hund's rule exchange interaction to reduce total magnetic moment of the dimer. We argue that the same mechanism could be relevant for other $4d$ and $5d$ dimerized transition metal compounds.
An Analysis of Scientific Epistemological Beliefs and Learning Orientations of Taiwanese Eighth Graders

The purpose of this study was to acquire a better understanding of the interaction between scientific epistemological beliefs and learning orientations in a group of Taiwanese eighth graders. After analyzing questionnaire responses of an initial sample of 202 students, 20 information- rich students were selected as the final subjects for this study. A qualitative analysis through inter- viewing of the subjects revealed that students holding constructivist epistemological beliefs about science (knowledge constructivists) tended to learn through constructivist-oriented instructional ac- tivities, and employ a more active manner as well as more meaningful strategies when learning science, whereas students having epistemological beliefs, more aligned with empiricism (knowledge empiricists), tended to use more rote-like strategies to enhance their understanding. Knowledge constructivist subjects tended to have more pragmatic views about the value of science and they were mainly motivated by their interest and curiosity about science, whereas knowledge empiricist subjects were mainly motivated by performance on examinations. This article suggests the impor- tance of presenting the constructivist philosophy of science for students. It follows that students are expected to have more meaningful orientations, as well as more appropriate attitudes, toward learning science. q 1998 John Wiley & Sons, Inc. Sci Ed 82:473- 489, 1998.
MONOCLONAL ANTI-IDIOTYPE ANTIBODY TO HSV-l NEUTRALIZING MONOCLONAL ANTIBODY : PRODUCTION AND CHARACTERIZATION

This study is an attempt to produce and characterize murine monoclonal antibodies directed against the paratope of HSV -I neutralizing monoclonal antibody. Monoclonal antibody 138 C5G 10 which was neutralising and directed to 120 K antigen gB of HS V -I was used as the idiotype. We were able to produce three Ab-2 monoclonal antibodies as characterized using immunofluorescence, ELISA and RIA. The findings of the present study suggest that two antiidiotypes 3AiB3E I 0 and 3AiB5D I 0 share the same unique fine specificity while 3AiB3C9 has a different specificity on 138 C5GIO paratope. The utility of such 'surrogate' antigens in serological assays and modulation of immune response is discussed.
Epidemiological Survey of Ascosphaera apis in Small-Scale Migratory Apis mellifera iberiensis Colonies

Honey bee hives are moved yearly mainly for pollination, but also to take advantage of consecutive flowering events to get as many harvests of honey as possible and/or to find favorable sites for food sources and summer temperatures. Such movements may lead to pathogen spill-over with consequences on the honey bee health and finally on population decline. Ascosphaera apis is the causative agent of the chalkbrood disease, a pathology affecting honey bee larvae that significantly harms population growth and colony productivity. In this study, we detected the presence of A. apis in adult worker honey bees by PCR-amplification of the intergenic transcribed spacer (ITS1) of the ribosomal gene (rDNA). We first optimized the DNA extraction by testing different protocols in individual and pooled (colony level) adult honey bee samples. Subsequently, the presence of the fungus A. apis was assessed in both stationary and migratory colonies (subjected to small scale regional level movements) to determine the effect of migratory practices on the dispersal of this pathogen. Results confirmed a higher prevalence of A. apis in migratory apiaries when compared to stationary ones, indicating that migratory colonies are more likely to develop chalkbrood disease. Given these results, we suggest that beekeepers should be aware of the risks of pathogens spreading while moving beehives, even within a reduced geographic range.
Emission and Dry Deposition Characteristics of Metal Elements from Engineering Construction Sites

In order to explore the emission characteristics of particulate and its particle-bound metal elements, eight construction sites in southem Taiwan were investigated during the period between Dec. 1996 and May 1997. Total suspended particulate (TSP) samples were collected with PS-1 samplers, and the dry deposition particles were sampled by dry deposition plates with smooth surfaces. The emission factors of particulate matter from construction sites were estimated using a dispersion model. Twenty elements, including Al, Ca, Fe, Mg, Na, Pb, Zn, Ni, V, Ba, Mn, Cr, Cu, Cd, Sr, Ag, Mo, Sb, As, and Ti, were analyzed in this study． The results indicated that dry deposition fluxes of TSP ranged between 762 and 3,760 mg/m(superscript 2)-day with an average of 2,230 mg/m(superscript 2)-day． The dry deposition velocities (V(subscript d)) of TSP varied in a narrow range between 2.63 to 5.55 cm/s with an average of 4.31cm/s and a standard deviation of l.21 cm/s. The major elemental components of particulate matter in the ambient air at construction sites were found to be crustal elements including Al, Ca, Fe, Mg and Na. These compositions were similar to those of road dust. Dry deposition fluxes of crustal metals were much higher than those measured at urban and suburban sites.

Direct Drive Linear Generator Designs with Aluminium Spacer and Alternate Slot Winding for Wave Energy Conversion System

This paper presents the study on direct drive linear generator designs with aluminium spacer and alternate slot winding for wave energy conversion system . The study involved the development of permanent magnet linear generator designs with the variation on aluminium spacer utilization as part of magnet assembly and alternate slot winding usage instead of conventional winding arrangement. The proposed designs were simulated using Finite Element Method (FEM) software to attain the results on flux distribution, air-gap flux density and open circuit results. The total weight and material cost of each design were also estimated. These results are significant in finding the acceptable design’s alternatives to counter the need of huge and heavy linear generator in wave energy converter system. Comparative studies on simulation results and calculated data were conducted between the alternative and conventional design. It is found out that alternate slot winding design improves the performance of conventional design with no impact on design’s weight and material cost while aluminium spacer design yields more significant negative results on the performance than the positive effects in term of design’s weight and material cost.
Pulse-Width Pulse-Frequency Based Optimal Controller Design for Kinetic Kill Vehicle Attitude Tracking Control

The attitude control problem of the kinetic kill vehicle is studied in this work. A new mathematical model of the kinetic kill vehicle is proposed, the linear quadratic regulator technique is used to design the optimal attitude controller, and the pulse-width pulse-frequency modulator is used to shape the continuous control command to pulse or on-off signals to meet the requirements of the reaction thrusters. The methods to select the appropriate parameters of pulse-width pulse-frequency are presented in detail. Numerical simulations show that the performance of the LQR/PWPF approach can achieve good control performance such as pseudo-linear operation, high accuracy, and fast enough tracking speed.
