Social anxiety moderates the links between excessive chatting and compulsive Internet use

Excessive online chatting can lead to unwanted consequences such as compulsive Internet use over time. Not all adolescents use chatting for the same purpose, however, and these links may not be as pronounced for socially anxious adolescents as they likely communicate with others online in order to compensate for offline social inadequacies. The current study investigated whether social anxiety moderated the links between excessive chatting and compulsive Internet use over time. Using a sample of 523 early adolescents (269 girls; M age = 14.00) from a 3-wave longitudinal study, the links between excessive chatting and compulsive Internet use were investigated via manifest autoregressive models, and moderating effects of social anxiety were tested via multiple-group comparison procedures. The results showed bidirectional links between excessive chatting and compulsive Internet use from Time 2–Time 3, as excessive chatting predicted more symptoms of compulsive Internet use, whereas compulsive Internet use predicted more excessive chatting – over and above the effects of gender. These links were present for adolescents low on social anxiety, but they were largely missing for highly socially anxious adolescents. Thus, social anxiety may have protective effects for early adolescents who spend too much time chatting online, as it may help reduce the risk of developing symptoms of compulsive Internet use.
Geographic variation in natal and early larval trace-elemental signatures in the statoliths of the market squid Doryteuthis (formerly Loligo) opalescens

We found distinct geographic differences in trace element concentrations in both the core and early larval areas of the statoliths of paralarval market squid Doryteuthis (= Loligo) opalescens at sites throughout the Southern California Bight, USA. Laser ablation inductively cou- pled plasma mass spectrometry (LA-ICPMS) of individual statoliths indicated detectable levels of Mg, Mn, Sr, and Ba, with marginal levels of Cr and Pb. While these paralarvae showed considerable within-sample differences in elemental concentrations, there was significant between-site discrimi- nation of natal (core) and early larval signatures for collection sites up to 100 km apart. In 2002 and 2003, levels of Ba and Sr in the statolith cores were significantly different among sites, suggesting dif- ferences in the natal environment or local maternal effects. Site specific differences in elemental sig- natures were also apparent for Mg and Mn in samples taken from outside the core in the early post- hatching period. These same portions of the statolith can be analyzed from adult squid collected on spawning grounds. We showed that concentrations of trace elements in the statolith cores of adults closely resembled the core signatures of squid paralarvae, which opens the possibility of identifying the source populations for stocks of this commercially important species.
Should Africa promote stock market capitalism

This paper considers the pros and cons of establishing stock markets in sub-Saharan African economies at the present stage of their development. It provides theoretical analysis and empirical evidence from both developing and advanced countries to argue that for many African countries such a development would be a costly irrelevance which they can ill afford; for a number of others, it is likely to do more harm than good. The African countries would do better to use their scarce human, material, and institutional resources to improve their banking systems than to promote stock markets.

Non-Newtonian Lid-driven Cavity Flow Simulation by Mesh Free Method

Non-Newtonian Lid-driven Cavity Flow Simulation by Mesh Free Method Abazar Shamekhi1, Abbas Aliabadi2 Summary Non-Newtonian lid-driven cavity flow is studied in a wide range of Reynolds numbers. The algorithm of mesh free characteristic based split has been extended for solving non-Newtonian flow problems in meshfree context. It is assumed that the non-Newtonian fluid properties obey Carreau-Yasuda rheological model. The results obtained from mesh free characteristic based split algorithm have been compared to the results of other meshfree methods. Results have been obtained for the velocity profiles at Reynolds numbers as high as 1000 for a Carreau-Yasuda fluid.
The tradition to donate among women in Javanese rural areas: Reciprocity, food exchange and monetization

In the history of the tradition to donate (Tradisi Nyumbang) in Javanese rural areas as reciprocity institution, food produce are the main form of gift. However, economic system has penetrated the social aspect of the tradition. Money use as the medium for donation replaced food produce is now a general practice in almost all villages. The research will show how women from underprivileged households in rural areas adhere to use food produce as social exchange tool in the tradition of donation. The produce itself has subjective meaning for the women rooted from the village culture and custom even if they are no longer involved in agricultural farming. The shift in women’s work pattern also characterizes food consumption pattern of the village. Many instant foods have displaced local food existence. This tradition to donate will portray how the moral economic of women villagers is being constructed. Key words: Reciprocity, food exchange, moral economy of the rural women.
Heterogeneity in Stock Pricing: A STAR Model with Multivariate Transition Functions

Stock prices often diverge from measures of fundamental value, which simple present value models fail to explain. This paper tries to find causes for these long-run price movements and their persistence by estimating a STAR model for the price-earnings ratio of the S&P500 index for 1961Q1 - 2009Q3, with a transition function that depends on a wider set of exogenous or predetermined transition variables. Several economic, monetary and financial variables, as well as linear combinations of these, are found to have nonlinear effects on stock prices. A two-step estimation procedure is proposed to select the transition variables and estimate their weights. This STAR model can be interpreted as a heterogeneous agent asset pricing model that makes a distinction between chartists and fundamentalists, where the set of transition variables is included in the agents’ information set.
Association between sleep pattern and body mass index among undergraduate health colleges’ students at Qassim University, Saudi Arabia

Background and objective: Better quality and adequate amount of sleep are essential to have better cognitive performance and by contrast, poor bedrest is related to a diminishing of cognitive and psychological functioning and deteriorating physical health. Recently the quality of sleep among various segments of the population has become a focus of continuous research and investigations, where insufficient sleep may lead to adverse cardio-metabolic effects by influencing body weight, blood pressure, and glucose tolerance. The objective of this study is to explore the associations between sleep patterns and Body Mass Index (BMI) among undergraduate female students in health colleges. Methods: Across-sectional study was utilized among 288 of undergraduate female students who represent 30% of all undergraduate students in health Colleges of female section, Qassim University. The data regarding their sleeping pattern was collected and calculated by using a validated self-report questioner (Pittsburgh Sleep Quality Index) and Body Mass. Results: According to PSQI scoring, both categories good and poor sleep maximum according to PSQI scoring; both categories good sleep and poor sleep maximum participant's BMI was normal but no statistically significant association was seen between BMI of poor sleep was higher in overweight and obese participants from all departments and also no statistically significant association was seen between poor sleep and body mass index of participant As for the sleep quality as a single question and sleep duration in relation to BMI for different specialties, only for nursing students there was a statistically significant difference of sleep quality/duration in relation to their BMI. Conclusions: Frequency of poor sleep was higher in overweight and obese participants but as per findings there was no statistically significant association was detected between PSQI score and BMI of participants.
Development of a solar concentrator with tracking system

Abstract. Solar Energy has been, since the beginning of human civilization, a source of energy that raised considerable interest, and the technology used for their exploitation has developed constantly. Due to the energetic problems which society has been facing, the development of technologies to increase the efficiency of solar systems is of paramount importance. The solar concentration is a technology that has been used for many years by the scientist, because this system enables the concentration of solar energy in a focus, which allows a significant increase in energy intensity. The receiver, placed at the focus of the concentrator, can use the stored energy to produce electrical energy through Stirling engine, for example, or to produce thermal energy by heating a fluid that can be used in a thermal cycle. The efficiency of solar concentrators can be improved with the addition of a dual axis solar tracker system which allows a significant increase in the amount of stored energy. In response to the aforementioned, this paper presents the design and construction of a solar dish concentrator with tracking system at low cost, the optical and thermal modelling of this system and a performance analysis through experimental tests. The experimental validation allows to conclude that the application of a tracking system to the concentrator is very important since a minimum delay of the solar radiation leads to important losses of system efficiency. On the other hand, it is found that the external factors can affect the final results which include the optical and geometrical properties of the collector, the absorptivity and the position of the receiver as well as the weather conditions (essentially the wind speed and clouds). Thus, the paper aims to present the benefits of this technology in a world whose the consumption of energy by fossil fuels is a real problem that society needs to face.
Semantic Processing of Foveally and Parafoveally Presented Words in a Lexical Decision Task

Using a lexical decision task in which two primes appeared simultaneously in the visual field for 150 msec followed by a target word, two experiments examined semantic priming from attended and unattended primes as a function of both the separation between the primes in the visual field and the prime-target stimulus-onset asynchrony (SOA). In the first experiment significant priming effects were found for both the attended and unattended prime words, though the effect was much greater for the attended words. In addition, and also for both attention conditions, priming showed a tendency to increase with increasing eccentricity (2.3°, 3.3°, and 4.3°) between the prime words in the visual field at the long (550 and 850 msec) but not at the short (250 msec) prime-target SOA. In the second experiment the prime stimuli were either two words (W-W) or one word and five Xs (W-X). We manipulated the degree of eccentricity (2° and 3.6°) between the prime stimuli and used a prime-target SOA of 850 msec. Again significant priming was found for both the attended and unattended words but only the W-W condition showed a decrement in priming as a function of the separation between the primes; this decrement came to produce negative priming for the unattended word at the narrow (2°) separation. These results are discussed in relation to the semantic processing of parafoveal words and the inhibitory effects of focused attention.
Reliability and Functional Availability of HVAC Systems

Summary This paper presents a model to calculate the reliability and availability of heating, ventilation and air conditioning systems. The reliability is expressed in the terms of reliability, maintainability and decision capability. These terms are a function of the mean time between failure, mean time to repair and decision time. The availability is expressed as an operational and functional availability of the systems. These terms are a function of both the technical and human characteristics to maintain the systems in correct operational state. The result is based on a large amount data from operational organisations, the compulsory inspection of ventilation systems and momentary and continuous measurements made in HVAC-systems.
Aflatoxin risk management in Texas: test kit approval for maize

Five commercially available quantitative test kits were evaluated for their capability to measure naturally contaminated maize samples at 59 µg/kg, 306 µg/kg, and 901 µg/kg aflatoxin levels. The aflatoxin contaminated maize samples, collected during the 2010 Texas corn harvest, were measured using high performance liquid chromatography (HPLC) following Association of Analytical Communities (AOAC) official method 2005.08. Five aflatoxin quantitative test kits approved for measuring aflatoxin contaminated maize containing <100 mg/kg by the United States Department of Agriculture (USDA) Grain Inspection Packers and Stockyard Administration (GIPSA) were evaluated by three analysts who analyzed seven 50 gram samples for each of the three sources of aflatoxin contaminated grain. The relative difference between the HPLC measurements and test kit results were analyzed using an analysis of variance. Significant two-way interactions were observed among the three explanatory variables including analysts, test kit, and aflatoxin level. No significant main effect was observed for analyst. All quantitative test kits performed within GIPSA prescribed performance criteria for the low and medium (59 µg/kg and 306 µg/kg) aflatoxin levels and were approved by the Texas State Chemist to measure aflatoxin contaminated maize as part of the Office of the Texas State Chemist’s (OTSC) aflatoxin risk management program. One test kit failed to perform within extrapolated GIPSA criteria at the 901 µg/kg.
Student-Athletes’ Perceptions of Men’s Basketball Head Coaches’ Competencies at 15 Selected NCC AA Division II Christian Colleges

The purpose of this study was to measure the perceptions of student-athletes concerning the coaching competency of 15 head men’s basketball coaches at the Division II level in the National Christian Collegiate Athletic Association (NCCAA). The study utilized the 24-item Coaching Competency Scale (CCS) to collect data on 138 student-athletes participating in men’s basketball from 15 NCCAA member institutions and examined four specific categories: character building competency (CBC), game strategy competency (GSC), motivation competency (MC), and technique competency (TC). Multivariate Analyses of Variance (MANOVA), Analyses of Variance (ANOVA), and Analyses of Covariance (ANCOVA) were computed to examine group differences for the 24 coaching competency factors. Results indicate that player-related factors of starter, non-starter, captain, non-team captain, and academic level were not significant predictors of the combination of coaching competency.

Tropical rainforest palm communities in Madre de Dios in Amazonian Peru

We studied palm communities, in particular species-richness and abundance, in the tropical rainforests in southeastern Peru in 54 transects (5×500m) covering an area of 13.5 hectares in flood plain, terra firme, terrace and premontane hills. We found 42 palm species in 18 genera in the transects. Terra firme forest had the highest species richness (38 species) followed by floodplain and premontane hills with 27 species and terrace forests with 26 species. The highest palm abundances were found in premontane hill forest which had 3243 palms per hectare and terra firme forest which had 2968 palms per hectare. The floodplain forests were intermediate in palm abundance with 2647 and the terrace forests had the lowest abundance with 1709 palms per hectare. Intermediate sized palms were the most common being represented by 18 species, while large palms were represented with 16 species. There were only eight species of small palms of which one was acaulescent. Only one species of liana palm was registered. Of the 42 species observed in the 54 transects, 20 were cespitose, 21 solitary and two had colonial growth. Seven species were found 40–320 km outside of their previously known range.
PHYSIOLOGICAL DISORDERS AFFECTING DENDROMETRIC PARAMETERS AND EUCALYPTUS WOOD QUALITY FOR PULPING WOOD

The productive sustainability of eucalyptus planting is threatened when both diseases and disorders of growth occur. These interferences can have abiotic origin as environmental conditions can negatively affect the wood quality. This study has the goal of evaluating influence of different levels of physiological disorders in dendrometric variables and wood quality from seven-year-old Eucalyptus grandis x Eucalyptus urophylla hybrids intended for wood pulping production. The trees from commercial plantations in State of Maranhão, Brazil were separated into three levels of physiological disorders by means of morphologic changes. Then, they were evaluated according to dendrometric variables, anatomical characteristics, chemical properties, density of wood, and kraft pulp process. The physiological disorder levels significantly influenced all evaluated properties. Moreover, the wood from trees with higher severity of symptoms resulted in higher average values of dendrometric variables, basic density, and fibers dimensions. In addition, apparent density exhibited a different standard in the pith region with increase on radial wood profile. Trees with the least severe disorders exhibited changes in dendrometric and anatomical variables, mainly in wood volume and fibers dimensions, respectively. v.24 n.1 2018 PHYSIOLOGICAL DISORDERS AFFECTING DENDROMETRIC PARAMETERS AND Eucalyptus wood QUALITY FOR PULPING WOOD

Modularization - Not Only a Product Issue

A constantly increasing product variety forces companies to deal with complexity. Companies have adopted the concepts of platform development and modularization in order to deal with this complexity. Even though these concepts have been tested and discussed during several years both in practice and in academia, most companies and literature focus solely on the product. Companies seem to fail in their modularization efforts partly because they underestimate the effects, for example the wide effects that modularization has on different organizational functions. The purpose of this paper is to identify important modularization areas and issues, for which there is a need of further research. These are areas that are of crucial importance in accomplishing and implementing modularization in manufacturing companies. We have spent the last five years doing research in the area of modularization. During this time, in-depth case studies were carried out at two vehicle-manufacturing companies. In addition to these results, we have done an interview-based survey with eight other companies. We have found that, in addition to the product, the product development process and organizational aspects are equally important to take into account when modularizing. Some cases are in this paper presented to illustrate these findings. The main conclusion that can be made from the findings presented in this paper is that modularization concerns more than the product. Also, the organization and the product development process are of great importance. Hence, when modularizing making changes to the product only is not enough. The existing organization and the product development process also have to be adapted to better suite the modularization and be suitable for the development of modularized products.
The Dividend Puzzle: A Summary Review of Explanations

Academics like to raise what-when-whether-why-how questions on interested topics. Nearly sixty years ago, J. Lintner has developed his model to explain how dividends are determined. Twenty years later, F. Black has asked why some firms pay dividends while others do not, and has written his famous paper â€œThe Dividend Puzzle. â€ And in-between, we have the dividend irrelevancy theory developed by Miller and Modigliani. After several decades with relentless effort by economists researching on the topic, the puzzle still seems to be here. Lots of theories or hypotheses have been developed to help understand the puzzle and what factors determining the distribution policy of a firm. This paper gives a summary review of those major explanations.
Rethinking Age Dependence in Organizational Mortality: Logical Fromalizations1

This article explores the use of logical formalization to clarify an area of research characterized by conflicting claims and divergent empirical findings. The substantive focus concerns the relation between organization age and the hazard of mortality. The literature contains claims that the hazard (a) falls with age (a “liability of newness”), (b) rises initially and then falls with age (a “liability of adolescence”), (c) rises with age (“liabilities of senescence and obsolescense”). The formalizations reported cast the relevant theoretical arguments as propositions involving five concepts: endowment, imprinting, inertia, capability, and position. It shows that each of the theoretical stories can be derived as implications of particular assumptions within two broad formalizations. This analysis clarifies the mechanizms at work in each theoretical account and provides guidance for expirical research designed to discriminate among the competing theories.
