The Role of Social Network Sites in Romantic Relationships: Effects on Jealousy and Relationship Happiness

On social network sites (SNS), information about one's romantic partner is readily available and public for friends. The paper focuses on the negative (SNS jealousy) and positive (SNS relationship happiness) consequences of SNS use for romantic relationships. We examined whether relationship satisfaction, trait jealousy, SNS use and need for popularity predicted these emotional consequences of SNS use and tested the moderating role of self-esteem. For low self-esteem individuals, need for popularity predicted jealousy and relationship happiness. For high-self-esteem individuals, SNS use for grooming was the main predictor. Low-self-esteem individuals try to compensate their low self-esteem by creating an idealized picture. Undesirable information threatens this picture, and especially individuals with a high need for popularity react with SNS jealousy.
Evidence that a Cerebellum‐Enriched, Synaptic Junction Glycoprotein Is Related to Fodrin and Resists Extraction with Triton in a Calcium‐Dependent Manner

Abstract: Subcellular fractions from rat cerebellum and other tissues were examined for the presence of a 240K glycoprotein, designated GP‐A. Previous results have shown that GP‐A is enriched in cerebellum synaptic junction (SJ) fractions when compared to parent synaptic plasma membrane (SPM) fractions and is not detected in forebrain SPM or SJ fractions. In the present studies, GP‐A was not detected in myelin, mitochondria, purified nuclei, or cytosolic fractions from cerebellum, but was present in microsomal fractions. GP‐A is partially soluble in the non‐ionic detergent Triton X‐100 and is completely soluble when cerebellum SPMs are treated with the ionic detergent N‐lauryl sarcosinate. The solubilization of GP‐A from cerebellum membranes was shown to be a function of bound calcium ions, e.g., pretreating SPMs with 100 μM‐1mM Ca2+ decreased the solubility of GP‐A in Triton by approximately threefold. GP‐A is a major concanavalin A (Con A)‐binding glycoprotein in cerebellum SJ fractions and migrates on sodium dodecyl sulfate (SDS) gels with a slower relative mobility than the 235K/ 230K fodrin doublet. Comparisons between purified fodrin and the 235K/230K doublet in cerebellum and fore‐brain synaptic fractions by two‐dimensional peptide mapping indicated that they were identical. The Con A‐binding property of GP‐A was exploited to purify it by affinity chromatography with agarose‐Con A. Peptide mapping comparisons between affinity‐purified GP‐A and GP‐A in SPM and SJ fractions indicated that GP‐A in synaptic fractions is apparently homogeneous. Peptide map comparisons between GP‐A and 235K fodrin polypeptide indicated that these two synaptic components are highly related (50% of their respective peptides are shared). The 235K fodrin polypeptide in SJs reacted with anti‐fodrin antisera on Western blots; however, GP‐A failed to cross‐react. These observations, together with results from previous studies, indicate that GP‐A is highly enriched in cerebellum compared to other neuronal and nonneural tissues. Moreover, GP‐A is enriched in SJs relative to SPM fractions, is related to fodrin, and is most likely a cell‐surface glycoprotein at asymmetric synapses in cerebellum. GP‐A may be involved in neuronal recognition or synaptic transmission in the cerebellum. The important role of calcium in synaptic transmission, together with the decreased solubility of GP‐A in Triton that results from micromolar concentrations of calcium, suggest that GP‐A may play a role in stabilizing cerebellar synaptic junctions.
Energetics and population ecology of Siberian herders

Methodological advances now permit human biologists to more effectively monitor energy dynamics in traditional societies. This study examines the nutritional ecology and energetics of semisubsistence herders of Siberia (Evenki) during a single season of their annual cycle (late summer). Total energy expenditure (TEE) among adults, as measured by daily heart‐rate monitoring, is greater in Evenki men (TEE = 11.9 ± 2.8 MJ/d in men and 8.8 ± 2.1 MJ/d in women; P < 0.001), a pattern that reflects the current division of labor under collectivized herding systems. Energy intakes are also greater among men (13.4 ± 5.6 vs. 8.5 ± 3.4 MJ/d; P < 0.01), and are, on average, sufficient to meet daily needs in both sexes. The Evenki appear to be in energy balance at the population level during the late summer (per capita energy intake = 9.0 ± 5.5 MJ/person/d; per capita requirements = 8.6 MJ/person/d); however, only small changes in food availability and/or energy expenditure are necessary to shift the population into negative balance during the winter. Primary sources of dietary energy include reindeer meat and other animal products (25–30%), foraged plant foods (10–15%), and nonlocal products (55–65%), such as flour, rice, and sugar. The anthropometric data indicate that the Evenki grow slowly and have small adult body size. Women are relatively heavier and fatter than men, and show a centripetal pattern of fat distribution. Evenki males appear to be undergoing a secular trend in stature, while no such increases are evident in females. These gender differences may reflect the differential impact to the changes associated with collectivization. Reduced metabolic requirements (due to declining activity and fertility levels), along with greater food availability, are likely to be responsible for the higher rates of obesity among Evenki women. © 1996 Wiley‐Liss, Inc.
e-Commerce adoption and business impact: a progress report

A substantial body of work has already been completed, under the Evidence Based Policy Fund programme, to examine business performance at firm level. This uses microdata collected as part of normal statistical surveys to examine the effects of specific inputs on firm performance. Early in 2002 ONS started to assess how survey data on e-commerce activity could be used in this type of analysis. There is strong policy interest in identifying the economic impact of ‘new economy’ inputs, and evidence on whether – and how – the use of Information and Communication Technology (ICT) affects firm behaviour and performance.
Second Hand Car Imports: A Threat or Extended Arm to the Zimbabwean Motor Industry

The study sought to find out whether second hand car imports are doing harm or good to the Zimbabwe Motor Industry. Respondents were drawn from individual motorists and car assemblers in Zimbabwe. Data analysis reveals that it is wrong to posit that second hand car imports are threat to the motor industry since the car assemblers themselves do not have the capacity to produce cars at affordable prices to the generality of the Zimbabwean customers. Rather the imports have proved a relief to customers who can not afford the costly local cars. The results imply car assemblers should strive to lower the assembly costs to be able to out-compete the second hand car imports.
What drives Greek consumer preferences for cask wine

Purpose – Cask wine (bag‐in‐box, soft pack) has not received considerable attention in wine marketing research, but interest among winemakers and consumers has been increasing steadily. However, little is known about what drives consumer preferences for cask wine and, furthermore, what the profile of the cask wine consumer is. This study aims at filling this gap.Design/methodology/approach – Based on a web‐based survey, the best‐worst scaling (BWS) method was applied to measure the importance of attributes that Greek consumers assign when choosing cask wine. Then, a latent class clustering analysis based on the importance ratings of the attributes was applied in order to segment the Greek cask wine market.Findings – The most important attributes were found to be price, quality and convenience packaging, whereas brand, grape variety and origin were found to be the least important ones. In relation to structure, the Greek cask wine market was found to consist of four distinct segments that were labelled as .
Performance evaluation studies of client-server models using SPEC Web99 benchmarks

The World Wide Web (WWW) has experienced tremendous growth over the past few years. This increase in use makes server load heavier and leads to more system-bound queries due to newly sought emerging Web techniques, such as information discovery and reuse, mining and fusion. There is an obvious interest in assessing the consequences of this growth and understanding the system's behavior under varying conditions and workloads. The overall performance of the WWW is affected by various criteria in terms of clients, servers, and the network. Measuring performance of a computer system is a complex, difficult and important task. Time and rates are usually the basic measures of system performance. Having more realistic data about system performance will be necessary in the design and development of integrated information systems and systems for reuse. The main objective of this work is to measure the performance of various Web-based computer systems and Web servers using the SPEC Web99 benchmarking toolset. In the experiments that we carried out, the server is set up using freely available Apache server software run on a Sun Sparc-Ultra 80 machine, and six Windows-based clients that are used to load the server using the benchmark suite. First, the effects of varying resources, such as memory sizes and processors, on server's performance are measured and analyzed. Then, we tested and evaluated the effects of six different clients and workload parameters on the server configuration. Amongst the six experiments that were performed, two were set up in order to test the client-side. Some of the parameters varied were memory sizes, number of processors, the workload, and the benchmark parameters. Some interesting results were obtained while others were as expected. The results indicate that good improvements can be achieved if workload and system resources are carefully chosen to optimize metrics of interest.
Analysis of the dairy value chain in the Dar es salaam milk shed, Tanzania

The general objective of this study was to analyze the dairy value chain in the Dar es Salaam milk shed in order to provide information for improving linkages between actors and efficiency in the value chain. Both primary and secondary data were used. Primary data were collected using Participatory Rapid Appraisal method and structured questionnaires administered to a sample of 125 dairy value chain actors. Concentration ratios were estimated to assess market power. Market margin was used to estimate the proportion of consumer price against producer prices while profit margin was estimated to assess efficiency at different nodes of the dairy value chain. The results of Descriptive statistics indicated that the dairy value chain was characterized by little value addition activities, small scale operations at all stages of the chain, seasonality of milk supply, poor quality control systems, poor handling, preservation and packaging practices of dairy products. Overall, the dairy value chain was weakly organized and coordinated. Analysis of market power using concentration ratio revealed higher market power for processors in terms of controlling prices and output than producers and marketing agents. Results of profitability analysis indicated variation in profit per liter of liquid milk equivalent with the highest profit obtained by processors, suggesting that, value addition could be a means of generating higher profits. However, opportunities for value addition were limited by several constraints including poor organization and coordination of the value chain, pricing constraints, low levels of milk hygiene, high operating costs, lack of milk collection centers, unreliable markets and poor infrastructure. These results suggest the need for promoting actors’ groups to encourage coordination between actors, promoting value addition through processing and proper packaging, promoting managerial skills in controlling costs of milk production and processing, promoting establishment of milk collection centers, improving road infrastructure and public transport systems. ii
Marketing Banks' Products in Nigeria for ImprovedCustomers' Satisfaction and Loyalty

The objective of this paper is to examine how the marketing of banks’ products in Nigeria can improve customers’ satisfaction and loyalty as sound marketing is critical to the success of every organization.Customer satisfaction determines the success or failure of a bank. In the banking industry, customers do not consider the price of products and services as major determinant in choosing banks to patronize, rather they consider first the bank’s quality of service delivery.Thus, one of the most acceptable tools for result-oriented business management is the effective and efficient use of marketing. More so,based on the opinions of some marketing experts,every business or organization is marketing.To achieve the objective of this paper, the author adopted a theoretical approach. Based on empirical studies reviewed and personal insights, the author concludes that effective marketing of banks’ products for improved customers’ satisfaction and loyalty must take into account service quality, product quality, price as well as sound marketing relationship management.
Facing Mother Nature

Homeowners insurance must be priced in accordance with the insured risk and associated costs. Any legitimate insurance arrangement, public or private, must manage its exposure so that it can satisfy its claims obligations if a disaster occurs. Following the devastating hurricane season that featured Katrina, the catastrophe insurance industry has been adapting its practices in order to better follow these precepts, but the industry has met opposition from state and federal legislators. There are private market solutions to the problem of managing and insuring catastrophe risk. Private catastrophe financing would work better if the government did not constrain and compete against it.
A Framework for Mobile Agent Security in Distributed Agent-Based E-Business Systems

Mobile agent systems provide a great flexibility and customizability to distributed applications like e-business and information retrieval in the current scenario. Security is a crucial concern for such systems, especially when they are used to deal with money transactions. Mobile agents moving around the network are not safe since the remote hosts that accommodate the agents can initiate all kinds of attacks and attempt to analyze the agents' decision logic and the agents' accumulated data. Hence, mobile agent security is one of the most challenging problems unsolved. This paper analyzes the security attacks to mobile agents by malicious hosts and proposes solutions based on public key authentication technique and cryptography to address some of these problems. An experimental application is developed, and security and performance of proposed solutions are also evaluated. A performance model is developed in order to tune the parameters of execution environment to meet the desired level of performance and security.

The positioning accounting reflects the results obtained are perceived in detailed analysis of the data under accounting perspective.
Improved SAR Amplitude Image Offset Measurements for Deriving Three-Dimensional Coseismic Displacements

Offsets of synthetic aperture radar (SAR) images have played an important role in deriving complete three-dimensional (3-D) surface displacement fields in geoscientific applications. However, offset maps often suffer from multiple outliers and patch-like artifacts, because the standard offset-measurement method is a regular moving-window operation that does not consider the scattering characteristics of the ground. Here, we show that by focusing the offset measurements on predetected strong reflectors, the reliability and accuracy of SAR offsets can be significantly improved. Application to the 2011 Van (Turkey) earthquake reveals a clear deformation signal from an otherwise decorrelated interferogram, making derivation of the 3-D coseismic displacement field possible. Our proposed method can improve mapping of coseismic deformation and other ground displacements, such as glacier flow and landslide movement when strong reflectors exist.
Organizing geographic information: The creation of the National Spatial Data Infrastructure

Prior to government regulations issued in OMB Circular A-16 in 1990, the organization and dissemination of geospatial data collected by the United State’s governments were unregulated and informal. Circular A-16 called for the creation of the Federal Geographic Data Committee (FGDC) and charged the FGDC with creating and implementing metadata standards for geospatial data. The importance of geospatial interoperability and metadata standardization between agencies was amplified in 1994 with EO 12906. EO 12906 called for the creation of a National Spatial Data Infrastructure (NSDI). A Spatial Data Infrastructure (SDI) is the coordination of the creation, collection, dissemination, and storage of spatial data between stakeholders in a spatial data community (Williamson, Rajabifard, and Binns 2005). This study explores the choices made by the FGDC on how to classify geospatial data across agencies and attempts to assess compliance among federal, state, and local governments to metadata standards in the creation of the NSDI.
Celebrity Endorsement: A Literature Review

Use of celebrities as part of marketing communications strategy is a fairly common practice for major firms in supporting corporate or brand imagery. Firms invest significant monies in juxtaposing brands and organisations with endorser qualities such as attractiveness, likeability, and trustworthiness. They trust that these qualities operate in a transferable way, and, will generate desirable campaign outcomes. But, at times, celebrity qualities may be inappropriate, irrelevant, and undesirable. Thus, a major question is: how can companies select and retain the 'right' celebrity among many competing alternatives, and, simultaneously manage this resource, while avoiding potential pitfalls? This paper seeks to explore variables, which may be considered in any celebrity selection process by drawing together strands from various literature.
Novel‐View Synthesis of Outdoor Sport Events Using an Adaptive View‐Dependent Geometry

We propose a novel fully automatic method for novel‐viewpoint synthesis. Our method robustly handles multi‐camera setups featuring wide‐baselines in an uncontrolled environment. In a first step, robust and sparse point correspondences are found based on an extension of the Daisy features [ TLF10 ]. These correspondences together with back‐projection errors are used to drive a novel adaptive coarse to fine reconstruction method, allowing to approximate detailed geometry while avoiding an extreme triangle count.
The Relation Between Firm Size and Size Growth Rate in European Carbonate Drinks Market

The aim of the study is whether Gibrat’s Law is true if applied on the carbonate soft drink markets in Eastern and Western Europe. The Gibrat’s Law means that the size increasing rate is not depend on the size of firms but randomly. It is tried to estimate the esence of the relationships between the initial size growth and growth rate of the firms, by using static mathod GMM and dynamic Arellano Bond panel. In static GMM it is not found a meaningful relations for Western European carbonate soft drinks firms but for Eastern European firms is. Even if, in Eastern Europe, there is a relation between size and size growth rate, which is different from Gibrat’s Law. Small size firms are more dynamic for growing than the large size firms, not randomly. In dynamic Arellano Bond model it is not meaningful to test the Gibrat’s Law. In the study the firm ’s size concept is limited with the sum of the sales valued in US Dollar for each of the firms.
The changing faces of Streptococcus antigen I/II polypeptide family adhesins

Streptococcus mutans antigen I/II (AgI/II) protein was one of the first cell wall‐anchored adhesins identified in Gram‐positive bacteria. It mediates attachment of S. mutans to tooth surfaces and has been a focus for immunization studies against dental caries. The AgI/II family polypeptides recognize salivary glycoproteins, and are also involved in biofilm formation, platelet aggregation, tissue invasion and immune modulation. The genes encoding AgI/II family polypeptides are found among Streptococcus species indigenous to the human mouth, as well as in Streptococcus pyogenes, S. agalactiae and S. suis. Evidence of functionalities for different regions of the AgI/II proteins has emerged. A sequence motif within the C‐terminal portion of Streptococcus gordonii SspB (AgI/II) is bound by Porphyromonas gingivalis, thus promoting oral colonization by this anaerobic pathogen. The significance of other epitopes is now clearer following resolution of regional crystal structures. A new picture emerges of the central V (variable) region, predicted to contain a carbohydrate‐binding trench, being projected from the cell surface by a stalk formed by an unusual association between an N‐terminal α‐helix and a C‐terminal polyproline helix. This presentation mode might be important in determining functional conformations of other Gram‐positive surface proteins that have adhesin domains flanked by α‐helical and proline‐rich regions.
Determinants of successful online transactions - effects of transaction assurance seal and reputation rating affecting trust and purchase intention of consumers

As the Internet continues to grow and flourish, more and more consumers like to buy things on the Internet. Online auction has become the biggest marketplace, because of the convenience and speed of online transactions. Ministry of Economic Affairs of Taiwan reported C2 C transaction rise by 20% annually, and its market is expected to grow continuously, meaning C2 C marketplace is receiving much increased attention. Nonetheless, there are many risks that come with online shopping. The lack of ability to inspect merchandise before purchase will put consumers a trick of fraud (identify theft). Therefore, effectively increasing consumers' trust in online sellers will make consumers more willing to buy goods from them. This study reported some characters that might influence consumers' trust in online sellers, and investigated the influence of trust on purchase intention. The focus of this study is to examine the consumers' perceived effect of sellers' transaction assurance seal, reputation and ability to protect trade information. With Yahoo! Auction as the research subject, 260 questionnaire surveys were conducted online, and 226 were considered effective. The research hypotheses were developed by using structural equation modeling (SEM), and the results supported the model.
