A comparison of teacher stress and school climate across schools with different matric success rates

Our aim was to investigate differences in teacher stress and perceptions of school climate among teachers from schools with differing matriculation success rates in the Limpopo province of South Africa. Two schools with matric pass rates of 100% and two schools with matric pass rates of less than 25% were selected from a list of schools provided by the province's Educational District Circuit. The schools were matched in terms of area, size, resources, and equipment. Thirty-three teachers from the high performing schools and forty-two teachers from the poor performing schools participated in the study. Student's t tests were used to assess the differences between the schools on the variables under investigation, and the results showed the teachers' experience of stress across the different schools was not significantly different, but significant differences did emerge with regard to school climate. The implications of these findings for the study population are discussed.
Van Allen Probes observations linking radiation belt electrons to chorus waves during 2014 multiple storms

During 18 February to 2 March 2014, the Van Allen Probes encountered multiple geomagnetic storms and simultaneously observed intensified chorus and hiss waves. During this period, there were substantial enhancements in fluxes of energetic (53.8–108.3 keV) and relativistic (2–3.6 MeV) electrons. Chorus waves were excited at locations L = 4–6.2 after the fluxes of energetic were greatly enhanced, with a lower frequency band and wave amplitudes ∼20–100 pT. Strong hiss waves occurred primarily in the main phases or below the location L = 4 in the recovery phases. Relativistic electron fluxes decreased in the main phases due to the adiabatic (e.g., the magnetopause shadowing) or nonadiabatic (hiss‐induced scattering) processes. In the recovery phases, relativistic electron fluxes either increased in the presence of enhanced chorus or remained unchanged in the absence of strong chorus or hiss. The observed relativistic electron phase space density peaked around L∗ = 4.5, characteristic of local acceleration. This multiple‐storm period reveals a typical picture that chorus waves are excited by the energetic electrons at first and then produce efficient acceleration of relativistic electrons. This further demonstrates that the interplay between both competing mechanisms of chorus‐driven acceleration and hiss‐driven scattering often occurs in the outer radiation belts.
Missed Opportunities: Innovation and Resource-Based Growth in Latin America

Latin America missed opportunities for rapid resource-based growth that similarly endowed countries-Australia, Canada, Scandinavia-were able to take advantage of. Fundamental to this poor performance was deficient technological adoption driven by two factors. First, deficient national"learning"or"innovative"capacity, arising from low investment in human capital and scientific infrastructure, led to weak ability to innovate or even take advantage of technologicaladvances abroad. Second, the period of inward-looking industrialization discouraged innovation and created a sector whose growth depended on artificial monopoly rents rather than the quasi-rents arising from technological adoption, and at the same time undermined resource-intensive sectors that had the potential for dynamic growth.
Reactions of Polynuclear Hydroxyaluminum Cations with Montmorillonite and the Formation of A 28-Å Pillared Complex

Polynuclear hydroxy-Al cations were prepared by partially neutralizing dilute solutions of aluminum chloride. These cations were introduced in the interlayer space of montmorillonite by cation exchange, which formed heat-stable pillars between the silicate layers. Polynuclear hydroxy-Al was preferentially adsorbed on montmorillonite compared with monomer-Al; the maximum amount adsorbed was ∼400 meq/100 g of montmorillonite. Of this amount 320 meq was non-exchangeable. The 001 X-ray powder diffraction reflection of the polynuclear hydroxy-Al-montmorillonite complex was at 27 Å, with four additional higher-order basal reflections, giving an average d(001) value of 28.4 Å. This complex was thermally stable to 700°C. An analysis of the basal reflections by the Fourier transform method indicated that the 28-Å complex had a relatively regular interstratified structure of 9.6- and 18.9-Å component layers with a mixing ratio of 0.46:0.54. This ratio implies that the hydroxy-Al pillars occupied every second layer. Considering the relatively small amount of Al adsorbed and the thermally stable nature of the structure, the hydroxy-Al pillars must have been sparsely but homogeneously distributed in the interlayer space.
Morpho-toxicology of chlorpyrifos to prolactin cells of a freshwater catfish, Heteropneustes fossilis

In the present study, an organophosphorus compound Coroban (active ingredient chlorpyrifos - E.C. 20%) was used. In short-term exposure the fish were subjected to 0.8 of 96h LC50 value of chlorpyrifos (1.76 mg L -1 ) for 96h. In long-term exposure the experiment was performed for 28 days by using 0.2 of 96h LC50 value of chlorpyrifos (0.44 mg L -1 ). Fish were killed on each time intervals from control and experimental (chlorpyrifos) groups after 24, 48, 72, and 96h in short-term exposure and after 7, 14, 21, and 28 days in long-term experiment. Blood samples were collected and sera were analyzed for calcium. Pituitary glands were fixed for histological studies and stained with Herlant tetrachrome and Heidenhain's azan techniques. Short-term exposure of chlorpyrifos caused decrease in the serum calcium levels. No change was noticed in the prolactin cells of chlorpyrifos treated fish. Long-term treatment with chlorpyrifos provoked hypocalcemia. The prolactin cells of treated fish exhibited slight degranulation after 21 days whereas the nuclear volume remained unchanged. After 28 days, the prolactin cells exhibited further degranulation and the nuclear volume recorded an increase. Cytolysis and vacuolization were also visible.
Milk production, milk fatty acid composition, and blood biochemical parameters of Holstein dairy cows fed whole or ground flaxseed instead of extruded soybeans in the first half of lactation

Summary To evaluate the effects of physically processed flaxseed [ground flaxseed (GFS) and whole flaxseed (WFS)] as a replacement for extruded soybeans on feed intake, milk production, milk composition, milk fatty acid (FA) composition and blood biochemical parameters, nine primiparus Holstein dairy lactating cows averaging 495 ± 34.5 kg of body weight (BW) and 70 ± 5 days in milk (DIM) were assigned in a 3 × 3 change over Latin square design with three periods. Intake of dry matter was similar among the animals fed the treatments, also milk yield and milk composition were not influenced by the diets. Processing of flaxseed significantly (P<0.05) affected plasma glucose and urea concentrations. Feeding ground compared with whole flaxseed and extruded soybeans, caused a significant (P<0.05) increase in the concentration of total long-chain fatty acids in milk, also α-linolenic acid (18:3) content nearly doubled with GFS compared with those of the other treatments (0.75 vs. 0.36 and 0.46 g/kg milk production for GFS, ESB or WFS, respectively). Linoleic acid (18:2), content of milk was also significantly (P<0.05) increased by inclusion of the ground flaxseed compared with the other treatments. In general, feeding ground flaxseed had a significant (P<0.05) effect on monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) concentrations compared with those of the cows fed extruded soybeans or whole flaxseed.
Customers’ Perceptions on the Objectives, Characteristics and Selection Criteria of Islamic Bank in Thailand

Due to relatively new establishment of islamic bank in Thailand and paucity of empirical research undertaken in the area, this study intends to capture the perceptions of Thai customers towards the objectives and characteristics of the islamic bank. In addition, this study aims to determine the important bank selection criteria as perceived by the customers and the differences in the perceptions of moslem and non-moslem customers were identified. The study surveys a sample of 462 respondents. The empirical findings show that the Thai customers know that the essential characteristic of the islamic bank is interest prohibition. They tend to support the idea that the islamic bank should strive to achieve its social objectives more than the commercial objectives. In addition, the results showed that there are differences between the Thai moslem and non-moslem customers’ preferences toward various bank selection criteria. The moslems highly considered the interest-free saving facilities, while the non-moslems tended to concern more about its reputation and image, and knowledgeable and competent personnel.
Effect of Split Nitrogen Applications on Durum Wheat Cultivars in Volcanic Soil

Durum wheat (Triticum turgidum L. var. durum) is an important crop for the world population and occupies a large cultivated area worldwide. New cultivars need constant improvement of their agronomic management, within which N fertilization is highlighted. Durum wheat is also important in Chile where genetic breeding and agronomic management have been developed to increase yield, industrial, and nutritional grain quality. The objective of this experiment was to determine the appropriate number of N applications during a crop cycle in a volcanic ash soil in South Central Chile. Nitrogen split applications were carried out on three durum wheat cultivars in a Melanoxerands soil during the 2003-2004 and 2004-2005 seasons. A rate of 200 kg ha -1 N was applied at different growing stages including planting, tillering, flag leaf, and heading (200-0-0-0, 100-100-0-0, 66-67-67-0, and 50-50-50-50 kg N ha -1 , respectively). The evaluated traits were grain yield, hectoliter weight, and wet gluten content. Results indicated that the use of two and three split N applications increased grain yield and wet gluten content with differences among genotypes. The best N split strategy corresponded to two and three N splits: at planting and tillering; at planting, tillering, and flag leaf, respectively.
Theory of Reasoned Action as an Underpinning to Technological Innovation Adoption Studies

There are a number of theories and models that have been employed over the years in understanding and studying users' technology adoption behaviors. These theories and models focus on people's intention to engage in a certain behavior such as the adoption and use of new technologies. The Theory of Reasoned Action (TRA) is one of such theories that have been widely used in technology adoption as well as used in a number of other research fields as a foundation to such studies. Most of the Information Systems scholars, who have used this theory, have used only to set a foundation or help build other theories and models. TRA has therefore been compared with other theories and models for technological innovation, and found to be a strong theory for innovation adoption upon a few additions of other variables such as facilitating conditions, awareness of innovation by users, social pressure and user readiness.
(Anti-)symmetrizing wave functions

The construction of fully (anti-)symmetric states with many particles, when the single particle state carries multiple quantum numbers, is a problem that seems to have not been systematically addressed in the literature. A quintessential example is the construction of ground state baryon wave functions where the color singlet condition reduces the problem to just two (flavor and spin) quantum numbers. In this paper, we adddress the general problem and provide a formalism that applies to generic number of particles and generic number of quantum numbers. As an immediate result, we find a complete solution to the two quantum number case, from which the baryon wave function problem with arbitrary number of flavors follows. As a more elaborate illustration that reveals complications not visible in the two quantum number case, we present the complete class of states possible for a system of five fermionic particles with three quantum numbers each. Our formalism makes systematic use of properties of the symmetric group and Young tableaux. Even though our motivations to consider this question have their roots in SYK-like tensor models and holography, the problem and its solution should have broader applications.
Survey of Nurses' Knowledge and Attitude Regarding Post Operative Pain Management at a Teaching Hospital in Malaysia

Post operative pain is an expected adverse outcome following surgery and it often delays mobilization and overall recovery. Acute post operative pain is subjective and cannot be measured directly. The objective of this study was to determine nurses’ knowledge and attitude towards post operative pain management. A cross sectional study was conducted in surgical wards and the Intensive Care Unit of Universiti Kebangsaan Malaysia Medical Centre from February to April 2008. A 28 item questionnaire which comprised of two domains: knowledge and attitude towards post operative pain management was used. Eighty four respondents successfully responded to the study. Twenty respondents (25%) possessed high level, 58 respondents (69%) possessed moderate level and 5 respondents (6%) had low knowledge level of post operative pain management. Positive attitude towards post operative pain management was reported by 66 respondents (78.5%). There was a significant relationship between nurses’ academic qualifications and attitude towards post operative pain management (χ² =29.96, p <0.05). In conclusion, nurses in UKMMC possessed moderate level of knowledge and positive attitude towards post operative management. Results of this study show the need to enforce continuing medical education in pain management amongst UKMMC nurses in enhancing the quality of post operative care.
Managerial Empathy Facilitates Egocentric Predictions of Consumer Preferences

Common wisdom suggests that managerial empathy (i.e., the mental process of taking a consumer perspective) helps executives separate their personal consumption preferences from those of consumers, thereby preventing egocentric preference predictions. The results of the present investigation, however, show exactly the opposite. First, the authors find that managerial empathy ironically accelerates self-reference in predictions of consumer preferences. Second, managers’ self-referential tendencies increase with empathy because taking a consumer perspective activates managers’ private consumer identity and, thus, their personal consumption preferences. Third, empathic managers’ self-referential preference predictions make them less likely to use market research results. Fourth, the findings imply that when explicitly instructed to do so, managers are capable of suppressing their private consumer identity in the process of perspective taking, which helps them reduce self-referential preference predictions. To support their conclusions, the authors present four empirical studies with 480 experienced marketing managers and show that incautiously taking the perspective of consumers causes self-referential decisions in four contexts: product development, communication management, pricing, and celebrity endorsement.
Mass spectrometry-based profiling of the carbon starved Escherichia coli proteome reveals upregulation of stress-inducible pathways implicated in biofilm formation and antibiotic resistance

Starvation is a complex adaptive response to insufficiency of nutrients that has been known to implicate a number of stress networks, and modulate pathogenicity and antibiotic resistance in bacteria. However, naturally occurring abrupt elimination of nutrients and prolonged periods of their complete absence, e.g. when bacteria are placed in natural or artificial water reservoirs, are qualitatively different from in-culture late stationary phase energy source diminution. Despite the obvious importance of proteomic investigation of bacteria exposed to nutrient deficiency, no comprehensive study on the subject has been published. In order to address the said shortage of knowledge, we decided to quantitatively look into the proteome-level alterations elicited by the complete lack of nutrients that constitute a viable source of carbon, i.e. carbon starvation, in the Escherichia coli HT115-derived SLE1 strain cells using the combination of label-free and SILAC-based proteomics. As a result, we obtained protein ratios for 1,757 and 1,241 protein groups for each technique respectively, 2D-annotated the quantifiable proteins present in both datasets, identified overand underrepresented Gene Ontology terms, and isolated protein groups ≥2-fold upand downregulated in response to carbon starvation (44 and 36 protein groups respectively). We observed upregulation of proteins implicated in various stress-related networks, most notably those that constitute the Gene Ontology term 'Biological adhesion', as well as various terms related to stress. Additionally, we identified several uncharacterized proteins, and our report is the first to ascribe them to a stress-induced proteome. Our data are available via ProteomeXchange with identifier PXD003255 and DOI:10.6019/PXD003255. INTRODUCTION Continuous development of mass spectra acquisition tools, in parallel with sophisticated bioinformatical data analysis environments, has ensured the rising popularity of mass spectrometry as a powerful technology for protein identification and quantification.

Managing News Coverage around Initial Public Offerings

"We examine opportunistic behavior of initial public offering (IPO) firms in Taiwan where they are required to disclose their own earnings forecasts and are unrestricted in releasing news around the offerings. We find that prior to the offerings, IPO firms tend to report higher earnings, disclose inflated earnings forecasts, and manage more good news. News management, however, emerges as the most predominant factor in aftermarket stock prices. In particular, IPO firms have a strong preference for releasing good news related to strategy/policy that may simply provide a vision of a firm's future. Furthermore, the news releases are often forward-looking when they are positive about the firms but tend to be realized when they are negative. IPO firms also tend to engage in more window dressing activities before a larger sale of IPO shares from existing shareholders or a larger decline in insiders' holdings. Our analysis shows that managerial optimism cannot fully account for their behavior". Copyright (c) 2010 Financial Management Association International.
Stochastic Feedback Policies under Alternative Management Regimes

A discrete-time stochastic bioeconomic model is developed and used to analyse the North Sea herring fishery under alternative management regimes. The analysis focuses on how catches and harvesting policies change with the price of herring. Two production functions are used to explain the harvesting process. At small stock levels, the choice of production function is seen to be critical for the model’s predictions. Feedback policies are found for the optimally managed fishery. The management of North Sea herring, after a moratorium was lifted in 1981, is evaluated with respect to effects on supply, stock level, and fishing effort. Under optimal management, the results imply that the fishery should have stayed closed until 1983, a conclusion that is independent of harvesting relationship used. Whether open access leads to total depletion or not is seen to depend on the choice of production function.
Distributed Algorithms for Target Localization in Wireless Sensor Networks Using Hybrid Measurements

This dissertation addresses the target localization problem in wireless sensor networks (WSNs). WSNs is now a widely applicable technology which can have numerous practical applications and offer the possibility to improve people’s lives. A required feature to many functions of a WSN, is the ability to indicate where the data reported by each sensor was measured. For this reason, locating each sensor node in a WSN is an essential issue that should be considered. In this dissertation, a performance analysis of two recently proposed distributed localization algorithms for cooperative 3-D wireless sensor networks (WSNs) is presented. The tested algorithms rely on distance and angle measurements obtained from received signal strength (RSS) and angle-of-arrival (AoA) information, respectively. The measurements are then used to derive a convex estimator, based on second-order cone programming (SOCP) relaxation techniques, and a non-convex one that can be formulated as a generalized trust region sub-problem (GTRS). Both estimators have shown excellent performance assuming a static network scenario, giving accurate location estimates in addition to converging in few iterations. The results obtained in this dissertation confirm the novel algorithms’ performance and accuracy. Additionally, a change to the algorithms is proposed, allowing the study of a more realistic and challenging scenario where different probabilities of communication failure between neighbor nodes at the broadcast phase are considered. Computational simulations performed in the scope of this dissertation, show that the algorithms’ performance holds for high probability of communication failure and that convergence is still achieved in a reasonable number of iterations.
Combining social axioms with values in predicting social behaviours

Recently, Leung et al. (2002) have identified a pan‐cultural set of five dimensions tapping beliefs about the world in which each individual functions. These general axioms may be conceptualized as individual assessments of the social context constraining one's behavioural choices. As such, we hypothesize that these beliefs about the world may be combined with measures of motivation to predict an individual's actions. To test this model, the present research examined the usefulness of these social axioms as predictors of behavioural tendencies in conjunction with four comprehensive dimensions of values (Schwartz, 1992). Hierarchical regression analyses showed that social axioms added moderate predictive power over and above that provided by values to vocational choices, methods of conflict resolution, and coping styles. Specifically, reward for application was related to preference for conventional jobs and accommodation in conflict resolution; religiosity was related to accommodation and to competition in conflict resolution; social cynicism was related negatively to collaboration and to compromise in conflict resolution, and positively to wishful thinking in coping; fate control was related positively to wishful thinking and distancing in coping; and social complexity was related to compromise and to collaboration in conflict resolution, and to problem‐solving as a coping strategy. It thus seems as if measures of respondents' beliefs about the external, social world supplement measures of their internal motivations to achieve various goals.

Inhibition of phytopathogens by certain strain of Azotobacter chroococcum under in vitro conditions

Siderophore positive and negative cultures of Azotobacter chroococcum were tested for inhibition studies. Different inhibition patterns were seen with fungal and bacterial phytopathogens. A methyl ammonium chloride resistant mutant, Mac 21, inhibited all phytopathogens excepting one fungal pathogen, Neovossia indica, which was, however, stimulated by all A. chroococcum culture supernatants tested except that of 100 and 54. Two mitomycin derived siderophore negative mutants Ml and M2 caused very low stimulation of Neovossia indica compared to their Fe- parent A. chroococcum 111. Antagonism of plant pathogens was seen with both Fe- and Fe+ culture supernatants of A. chroococcum although the degree of antagonism was different.
