Physico-Chemical Characterization of an Urban Hydrosystem (Ebolowa Municipal Lake, South-Cameroon): Application of the Principal Component Analysis (PCA) for the Water Typology Identification

This study was carried out in order to characterize on the physico-chemical level the waters of Ebolowa Municipal Lake. To study this hydrosystem, three sampling sites (S1, S2 and S3) were monitored throughout a seasonal cycle, to identify the lake water typology based on the characteristics of effluents discharged in to it. Fifteen parameters were measured in the field and in the laboratory on the three sites. The results obtained have been subject to multi-variate statistical treatment via the Principal Component Analysis (PCA), and revealed that sampling sites S1 and S3 are the most polluted, while site S2 shows moderate pollution. Three distinct water typology groups were highlight : the first one corresponding to waters of site S1, is the group of water rich in organic matter ; the second one, group of mineralized, deep and oxygen rich waters correspond to waters of site S2 ; and the last one corresponding to waters of site S1 is the group of turbid waters rich in suspended matters. The anthropic activities developing near this water body are undoubtedly the cause of this pollution.
Algorithmic Trading in Turbulent Markets

This paper considers algorithmic trading (AT) during the most volatile trading days on the Australian Securities Exchange from October 2008 till October 2009. We show a significant negative association between the level of AT activities in a particular stock and the stock's price swings. This effect is driven by algorithmic traders closely monitoring volume-weighted average prices in their execution strategies. We also provide strong evidence that the order imbalances of algorithmic traders have a smaller impact on the abnormal returns of individual stocks compared to order imbalances based on non-algorithmic trading.
Selected Macronutrient Uptake by Sweet Corn under Different Rates of Liquid Organic Fertilizer in Closed Agriculture System

In the last few years, soil deterioration due to excessive application of synthetic agrochemical has become growing concern. Use of organic fertilizer is believed to be able to enhance soil quality. The objective of this experiment was to determine nitrogen, phosphorus, and potassium uptakes by sweet corn as affected by local based liquid organic fertilizer (LOF) under closed agriculture system. The experiment was conducted in Closed Agriculture Production System (CAPS) Research Station in Air Duku Village, Bengkulu, Indonesia from March to June 2015, employing Randomized Completely Block Design with 2 factors. The first factor was 3 sweet corn genotypes, i.e. Talenta, Jambore, and Asian Honey and the second factor was 5 rates of LOF, i.e. 0, 25, 50, 75, and 100 mg l-1, respectively. Each treatment combination was replicated 3 times. Foliar application of LOF was carried out every week at 2-8 weeks after planting (WAP) with total volume of 600 ml per plant. Sweet corn leaves were sampled at the beginning of tassel emergence. The experiment revealed that sweet corn genotype significantly influenced the uptake of nitrogen, but not phosphorus and potassium. It was observed that Asian Honey genotype absorbed highest nitrogen as compared to other genotypes. In addition, increase in rates of LOF significantly raised nitrogen uptake by sweet corn, but not phosphorus and potassium.

THE REDISCOVERY OF POSTPONEMENT PREPARING FOR THE NEXT MILLENIUM MASS CUSTOMIZED SUPPLY CHAIN This paper reviews available work on postponement based upon the notion that there is a growing attention for the concept in research and practice. This is driven by the move towards mass customization in supply chains. There is however, a lacking integration and cross-fertilization between research(areas). ll1is fragmentation implies that new work has a reduced impact on knowledge creation. This paper develops an integrated categorization of available publications and identifies white gaps in knowledge. Challenges for content and method of research in the new supply chain context are formulated to support more robust and integrated research into the next millenium. Key-words: Literature review, postponement, supply chain
Regularization of Hyperfunctions

We show that there are no continuous regularization procedures for the extension of hyperfunctions. We also show that there is a continuous projection operator from the space of hyperfunctions with support in a given compact set onto the subspace of hyperfunctions with support on a given closed subset if and only if the subset is a countable intersection of sets that are closed and open.
GENDER EARNINGS GAP IN URBAN PAKISTAN: EVIDENCE FROM ORDINARY LEAST SQUARES AND QUANTILE REGRESSIONS

The objective of this paper is to analyze the gender earning gaps existing in urban areas of Pakistan using data from a household survey. The earning functions have been estimated separately for males and females using Ordinary Least Squares (OLS) as well as quantile regressions including education, literacy, experience, employment related variables such as type of industry and occupation and age as explanatory variables. The earning gaps between males and females have also been analyzed using the Blinder-Oaxaca decomposition method. Results suggest higher mean earnings for males as compared to females but higher incremental returns to investment in human capital for females at all levels of education. Further, higher returns to schooling have also been noted in bottom part of the income distribution i.e. 5 th & 25 th quantiles for workers of both sexes as compared to those present in the top of the distribution i.e. 75 th & 95 th quantiles at all educational levels. Education, industry of employment and occupations has been emerged as the main determinants of income gap between male and female workers in urban Pakistan.

INHIBITION OF LIPOXYGENASES AND CYCLOOXYGENASES BY Momordica charantia

Momordica charantia (MC) is a climber belongs to the Cucurbitaceae family. While there are accumulating evidences showing its pharmacological activities, the effects of fractionation and processing on its anti-inflammatory activity have not been fully elucidated. In this study, we aimed to investigate the anti-inflammatory effects of MC raw juice and fractions from MC fruit extract and to evaluate the effect of processing methods on its anti-inflammatory activity. First, MC juice was extracted using a conventional juicer (raw juice) and fractionated using a solid phase extraction method into five fractions; strong acid, weak acid, neutral, weak base, and strong base fractions. The raw juice and its fractions then were tested for their anti-inflammatory activities including cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LOX), and 15-lipoxygenase (15-LOX) inhibition assays. The results showed that the COX-1 inhibition activity of MC can be attributed to the neutral metabolites (52.60% inhibition). In contrast, the anti-COX-2 activity of MC was found exerted collectively by metabolites in multiple fractions (strong base, neutral, strong acid fractions). Contrarily, metabolites from all five fractions contributed to the MC inhibition activities on 5-LOX (55.51% inhibition for raw juice) and 15-LOX (55.3% inhibition for raw juice). Additionally, the current findings showed that the juice processing technique influenced the plant bioactivity, where juice extract obtained from slow juicer showed consistently higher anti-inflammatory activities than juice from conventional juicer. In summary, the current study provided evidences of anti-inflammatory action of MC and its fractions, which may contribute towards an improved processing and fractionation strategy.
Evidence of mantle-rooted fluids and multi-level circulation ore-forming dynamics: A case study from the Xiadian gold deposit, Shandong province, China

Metallogensis of the Xiadian gold deposit in Shandong Province has been a question under dispute for a long time. There are many points such as metamorphic hydrothermal, magamatic hydrothermal and meteoric water. Detailed study shows that mantle-rooted fluids were involved in the ore-forming processes. Evidence for this argumentation comes from: (1) discor-dogenic fault; (2) intersecting and accompanying of basic veins and lodes; (3) geochemistry of stable isotopes; (4) geochemistry of fluid inclusions; and (5) multi-level circulation and exchanging of mantle-rooted fluids. Based on the characteristics of the circulation system of mantle-rooted fluids and its close relation to magmatic hydrothermal fluids and meteoric water, ore-bearing fluids are divided into three subsystems: (1) C-H-O-rich fluid circulation subsystem in mantle, (2) Si-rich fluid circulation subsystem in the middle and lower crust; and (3) S-rich fluid circulation subsystem in shallow and surface crust. Ore-forming functions of these subsystems are controlled respectively by their different geodynamic settings.
The Effect of Socio-Affective Variables in the Relationship between Organizational Trust and Employee Turnover Intention

Employee turnover leads to lowered productivity, decreased morale and work quality, and psychological effects associated with employee separation and replacement. Yet, it remains unknown why talented employees willingly withdraw from organizations. This uncertainty is worsened as studies; a) priorities organizational over individual predictors resulting in restriction in range in turnover measurement; b) focus on actual rather than intended turnover thereby limiting conceptual understanding of the turnover construct and its relationship with other variables and; c) produce inconsistent findings across cultures, contexts and industries despite a clear need for a unified perspective. The current study addressed these gaps by adopting the theory of planned behavior (TPB) framework to examine socio-cognitive factors in organizational trust and individual turnover intentions among bankers and energy employees in Jamaica. In a comparative study of n=369 [nbank= 264; male=57 (22.73%); nenergy =105; male =45 (42.86)], it was hypothesized that organizational trust was a predictor of employee turnover intention, and the effect of individual, group, cognitive and socio-affective variables varied across industry. Findings from structural equation modelling confirmed the hypothesis, with a model of both cognitive and socio-affective variables being a better fit [CMIN (χ2) = 800.067, df = 364, p ≤ . 000; CFI = 0.950; RMSEA = 0.057 with 90% C.I. (0.052 0.062); PCLOSE = 0.016; PNFI = 0.818 in predicting turnover intention. The findings are discussed in relation to socio-cognitive components of trust models and predicting negative employee behaviors across cultures and industries. Keywords—Context-specific organizational trust, cross-cultural psychology, theory of planned behavior, employee turnover intention.
Effect of Teachers ’ Emotions on Their Students : Some Evidence

This work attempts to compile some of the different effects that professorial emotions have upon students by searching relevant scientific literature. As a result, presented here is a series of influences, classified by considering six areas of effects about which empirical evidence has been gathered: students' emotions, emotional competence, motivation, academic performance, classroom discipline, and social behavior. Furthermore, herein are expounded both positive and negative effects that come to play in each of the discrete emotions mentioned. The results reveal that, excluding certain exceptions in the context of specific circumstances, it is determined that positive emotions provoke positive effects, while negative emotions provoke negative effects. Following is a discussion of the appropriateness, or lack of the same, in the suppression of negative emotions, encouraging positive ones; the function of emotional regulation of teachers; and the possible benefits of the inclusion of emotional competence as a formative part of teacher preparation.
Biochemical Changes, Use of Polyethylene Bags, andChilling Injury of Carambola (Averrhoa carambola L.)Stored at Various Temperatures

The effects of storage temperature and the use of polyethylene film on chilling injury and biochemical changes in carambola (Averrhoa carambola L.) fruits were studied. The pH, total soluble solid changes were not significantly different in ripe and unripe fruits stored at 5°, 10°, 15° and 20°C. No starch was detected in either ripe or unripe fruits, and no significant changes occurred in the total sugar content. Unripe fruits pacted in sealed perforated and nonperforated polyethylene bags stored at 20° C those in perforated bags or the control after 1 and 3 weeks in storage. Chilling injury of unripe carambola fruits, less than 25% full yellow in colour, occurred after 5 weeks in storage. The degree of injury was slight but became more severe as storage time lengthened. The ribs of the fruits turned black and dark brown patches appeared on the surface of the skin. Unripe fruits having less than 25% yellow colour on the skin surface suffered chilling injury after 5 weeks storage at 5° C. The severity increased with storage time. The physiological disorder appeared as dark green brown patches on the skin, shrivelled and darkened ribs, and failure of the fruits to turn yellow when transferred to 20° C. INTRODUCTION An important chemical composition of a fruit that determines its sweetness at maturity is the amount of sugar present. Chan and Heu (1975) identified the major sugars in carambola as fructose, glucose, and sucrose. Pratt lFood Technology Division, MARDI, Serdang, Selangor. 39 et al. (1977) found
Temporal stability of free liquid threads with surface viscoelasticity

We analyse the effect of surface viscoelasticity on the temporal stability of a free cylindrical liquid jet coated with insoluble surfactant, extending the results of Timmermans & Lister (J. Fluid Mech., vol. 459, 2002, pp. 289–306). Our development requires, in particular, deriving the correct expressions for the normal and tangential stress boundary conditions at a general axisymmetric interface when surface viscosity is modelled with the Boussinesq–Scriven constitutive equation. These stress conditions are applied to obtain a new dispersion relation for the liquid thread, which is solved to describe its temporal stability as a function of four governing parameters, namely the capillary Reynolds number, the elasticity parameter, and the shear and dilatational Boussinesq numbers. It is shown that both surface viscosities have a stabilising influence for all values of the capillary Reynolds number and elasticity parameter, the effect being more pronounced at low capillary Reynolds numbers. The wavenumber of maximum amplification depends non-monotonically on the Boussinesq numbers, especially for very viscous threads at low values of the elasticity parameter. Finally, two different lubrication approximations of the equations of motion are derived. While the validity of the leading-order model is limited to small enough values of the elasticity parameter and of the Boussinesq numbers, a higher-order parabolic model is able to accurately capture the linearised behaviour for the whole range of values of the four control parameters.
The Influence of Placebo Cognitive Enhancing Drugs on Proactive and Reactive Cognitive Control: An EEG-Study

The Dual Mechanisms of Control framework postulates that cognitive control consists of two complementary components: proactive control, which reflects an anticipatory and top-down mode of cognitive control, and reactive control, which is a stimulus driven mode of cognitive control that is recruited as a reaction to interference or conflict detection. In our study we wanted to analyze the dynamics of cognitive control after a placebo manipulation, which consisted of a sham double-blind experimental design, a placebo cognitive enhancer and a manipulated numeral cognition task (NCT), by which we wanted to deceive participants’ performance perception. Cognitive control was tested by a Cued Emotional Conflict Task (CECT), during which we registered reaction times, accuracy scores and Event Related Potentials. Inter-individual variability in suggestibility or placebo manipulability was measured using two sources: a self report questionnaire and the performance measurements of the NCT. Results showed that participants who reported to experience more positive effects of the taken placebo, reacted significantly faster during the cued emotional conflict task. Moreover, these placebo related experiences mainly facilitated the reaction times during the cognitive control trials, that require more proactive control. Associated with proactive control, ERP-data of our control group also showed smaller CNV amplitudes during the cognitive control trials, which suggests increased working memory load or task related goal representation.
Earnings Yield as a Predictor of Return on Assets, Return on Equity, Economic Value Added and the Equity Multiplier

This study identifies earnings yield as a measure of financial performance that is based on a firm’s ability to sell profitable goods. It excludes the irrationality that can confound market-based measures of financial performance by emphasizing a firm’s ability to earn profits as the indicator of superior performance. For the full sample, the differential effects of earnings yield on return on assets, return on equity, stock returns, economic value added and the equity multiplier are determined for firms of different size and volatility. The analysis is conducted both across industries and within the oil and gas, computer software, biotechnology and retail industries. For the full sample of NASDAQ stocks from 2010-2014, earnings yield significantly explained return on assets, return on equity, stock returns, economic value added and the equity multiplier beyond book value and book to market. The influence of earnings yield on return on assets was predictable with linear relationships and autocorrelated residuals, while that for small firms was unpredictable with nonlinear relationships between earnings yield and all outcomes with heteroscedastic residuals. In the oil and gas industry, small producers with low market risk and high firm-specific risk, i.e. drillers in new locations with existing technology, found that earnings yield was related to all outcome measures, while large, high-market risk firms, or drillers using the new shale rock techniques strove for operational efficiency through higher return on assets and return on equity. Market risk demarcates small biotechnology firms with those with low market risk demonstrating the explanation of return on assets by earnings yield, while earnings yield is significantly related to economic value added for high market risk firms. In large biotechnology firms, earnings yield was significantly related to all outcomes. Similar results were obtained for the computer software industry. Retail is in retrenchment with small retailers selling traditional product lines emphasizing return on assets or being operationally efficient for survival, while large retailers borrow against large-scale investments in assets, as shown by the significant explanation of the equity multiplier by earnings yield. It may be concluded that earnings yield measures multiple dimensions of financial performance for firms of different size and volatility levels in multiple industries. For small firms, the ability of earnings yield to measure the productivity of capital through economic value added is noteworthy. For large firms, earnings yield is particularly effective in predicting operational efficiency or return on assets.
The Psychology of Everyday Things

For whatever reason consciousness evolved, our awareness of ourselves in our ecological niche would be expected to be experienced as compatible. The industrial revolution challenged this compatibility because many individuals worked and lived in inhumane conditions. The technological revolution provides another (less compelling) challenge to this compatibility. Donald A. Norman's goal is to help relieve feelings of incompatibility by putting the blame on the poor design of everyday things in our environment rather than on ourselves. When we fail to deal appropriately with our environment of water faucets, doors, and VCRs, we usually blame ourselves. Norman demonstrates that much of the blame should be placed on the designer and, in so doing, illustrates once again that psychology is relevant to our everyday life. Theories developed and tested in the laboratory can be used to rationalize behavioral successes and failures in everyday life. Although the book seeks to show that the incompatibility is due to the environment and not the participant, it does not address the reason that we blame ourselves. Perhaps our psychology might also speak to this issue as well as the other.
