Analysis of social network sites diffusion in Mongolia

This paper is proposed to examine the diffusion of social network sites in Mongolia, as well as to understand diffusion pattern at aggregate level. The historical data on the number of monthly subscribers were obtained from two newly launched Mongolian social network sites, Voodoo.mn and Biznetwork.mn. Additionally, the Bass diffusion model was employed as a forecasting technique following nonlinear least square (NLS) approach, and model parameters were estimated using LINGO 9.0 optimization software. It is found that the social network sites diffusion followed traditional S-shaped curve. The results supported for application of Bass model in forecasting diffusion of social network sites in Mongolia. It showed that, the social networking market consisted mainly of imitators. Particularly, social network sites in Mongolia were noted to approximately reach maturity. Keywords: Social network sites, diffusion of innovation, bass model.
Adaptive mobile access protocol (AMAP) for the message service of a land mobile satellite experiment (MSAT-X)

This paper describes a feasibility study of the adaptive mobile access protocol (AMAP) for MSAT-X, a proposed experimental mobile satellite communication network. The mobiles are dispersed over a wide geographical area and the channel data rate is limited due to the size and cost limitations of mobile antennas. AMAP is a reservation based multiple-access scheme. The available bandwidth is divided into subchannels, which are divided into reservation and message channels. The ALOHA multiple-access scheme is employed in the reservation channels, while the message channels are demand assigned. AMAP adaptively reallocates the reservation and message channels to optimize system performance. It has been shown that if messages are generated at a rate of one message per hour, AMAP can support approximately 2000 active users per 2400 bit/s channel with an average delay of 1.4 s.
Systems Organizations and the Suppressing Factors Related to IS Evaluating the Driving Factors Outsourcing in Four Finnish Information

This chapter presents the results of a research project, in which the cur- rent situation related to the information systems (IS) outsourcing practices in four Finnish information systems development organizations was evaluated. The evaluation was based on employees' own perceptions, and it consisted of analyz- ing the current IS outsourcing practices in the case companies, driving factors re- lated to IS outsourcing, suppressing factors related to IS outsourcing and an evaluation of the company's readiness to utilize IS outsourcing. This qualitative study used grounded theory as the research method. The analysis elicited that the IS outsourcing decisions in these case companies have been mostly based on cost- related factors. The cost pressures are coming both from the shareholders and the customers. Cost reduction seemed to be the major single driver for outsourcing in- formation system development (ISD) work. Besides, even if most of the case companies have already outsourced parts of their ISD projects, based on the inter- viewees' expressions the cost savings in these projects have not been remarkable. In some cases the total costs of the project have been estimated to be even higher. However, the case companies seem not to be familiar with the cost structure of the outsourced projects. The interviewees also felt that their company's ISD practices were not ready for the use of outsourcing. The level of English skills and the lack of domain knowledge among subcontractors were the other mentioned suppress- ing factors related to IS outsourcing.
The Scream

I was lucky to be in London in May and catch Fram, Tony Harrison’s latest play,* in its short but spectacular run at the Olivier Theatre at London’s National Theatre. The play, all in rhyming verse, begins in Westminster Abbey, with moonlight shining through the stained glass of the great Rose Window, casting a reflection of Aeschylus on the cold stone floor. In walks the ghost of Gilbert Murray (Jeff Rawle), rising up from his grave and carrying a tragic mask. Murray, the early-twentieth-century Oxford professor and classicist, was also a humanitarian, deeply involved in the League of Nations and the United Nations and co-founder of Oxfam. But since his death fifty years ago, his once-admired verse translations of Aeschylus and Euripides have been scorned, and the world he tried to save has been ravaged by even more unimaginable horrors. So instead of decomposing in his urn, he has spent his afterlife composing this play. He calls up the spirit of Sybil Thorndike (Sian Thomas, as splendid as the character she plays), the actress who triumphed on the London stage as Clytemnestra, Hecuba, and Medea in Murray’s once wildly popular versions, and whisks her off to the Olivier stalls of the National Theatre—for Fram is not just a play within a play, but a theater within a theater. Most of all, it is a poem about poetry. The hero of the play is Fridtjof Nansen (Jasper Britton), Murray’s long-ago friend (and admirer of his translations)— the dashing Norwegian scientist, artist, and Arctic explorer
Human B19 Erythrovirus In Vitro Replication: What's New?

Human B19 erythrovirus (B19) tropism is almost restricted to erythroid progenitor cells and mediated by receptor and coreceptor interactions: i.e., P antigen ([2][1], [3][2]), α5β1 integrin complex ([20][3]), and Ku80 antigen ([11][4]). Few in vitro models allow production of B19 infectious

Pension Reform and Financial Markets

The question of the links between pension reform and financial markets has two aspects. One concerns the preconditions in terms of financial sector development for the successful implementation of pension reform, while the other refers to the long-term impact of pension reform on the development of financial markets. This paper argues that pension reform and the promotion of private pension funds requires a small core of sound, prudent and efficient financial institutions, such as banks and insurance companies, but does not depend on the prior existence of well-developed securities markets. Private pension funds and insurance companies are likely to have a beneficial impact on financial market development once they reach critical mass and provided they operate in a conducive regulatory environment.
UK CONSUMERS' ADOPTION OF THE INTERNET FOR GROCERY SHOPPING

Internet shopping has become one of the fast-growing areas of UK retailing and most online shoppers use information gathered online to make grocery purchases. Many British shoppers also perceived shopping on-line as risky. Attitude theories relating to grocery shopping online have been used to evaluate the UK grocery shoppers’ use of the Internet for grocery purchases. The review shows that the future success of the Internet will mostly depend on the extent to which current shoppers accept and use the Internet as a medium for grocery purchasing. It is recommended that in designing their websites, retailers bear in mind that the Internet serves as a virtual retail environment where exchange between shoppers and retailers takes place.
A Study on The Evaluation for Quality Factors of SNS and SNS Media by Using AHP

Nowadays, SNS media has become one of the most common and economic communication methods in the modern word. With the rapid development of communication technology, a variety of SNS media makes easier for us to reach other people everywhere and people are getting more and more reliant on them. The surge in SNS media users and SNS media diversity gets more important every day, but academic research on SNS media evaluation program is scanty. In order to present an evaluation program on the SNS media, this study selected some applicable measurement factors based on reference research, and then evaluate major SNS medias by using AHP analysis method. With these purposes, Kakaotalk, Twitter and Facebook, are the three major SNS medias that were chosen for the analysis. Through collections and analysis of usability evaluation factors about SNS quality from related literature, some factors were concluded: system quality, information quality, interface quality and service quality, to build an AHP frame. And to achieve these purposes, this study applied comprehend mutual questionnaire survey for experts and users to gather research date. Empirical studies about the results were performed using AHP method with Microsoft Office Excel 2010. In this study, the final SNS media evaluation result is that Kakaotalk ranks first of the three SNS media, Facebook is in the second place, and Twitter as least. When SNS media are evaluated, system quality, information quality, interface quality and service quality should be considered. Among all factors, service quality is the most important. ▸
Diffusion Stop-Layers for Superconducting Integrated Circuits and Qubits With Nb-Based Josephson Junctions

New technology for superconductor integrated circuits has been developed and is presented. It employs diffusion stop-layers (DSLs) to protect Josephson junctions (JJs) from interlayer migration of impurities, improve JJ critical current (Ic) targeting and reproducibility, eliminate aging, and eliminate pattern-dependent effects in Ic and tunneling characteristics of Nb/Al/AlOx/Nb junctions in integrated circuits. The latter effects were recently found in Nb-based JJs integrated into multi layered digital circuits. E.g., it was found that Josephson critical current density (Jc) may depend on the JJ's environment, on the type and size of metal layers making contact to niobium base (BE) and counter electrodes (CE) of the junction, and also change with time. Such Jc variations within a circuit reduce circuit performance and yield, and restrict integration scale. This variability of JJs is explained as caused by hydrogen contamination of Nb layers during wafer processing, which changes the height and structural properties of AlOx tunnel barrier. Redistribution of hydrogen impurities between JJ electrodes and other circuit layers by diffusion along Nb wires and through contacts between layers causes long-term drift of Jc. At least two DSLs are required to completely protect JJs from impurity diffusion effects-right below the junction BE and right above the junction CE. The simplest and the most technologically convenient DSLs we have found are thin (from ~3 nm to ~10 nm) layers of Al. They were deposited in-situ under the BE layer, thus forming an Al/Nb/Al/AlOx/Nb penta-layer, and under the first wiring layer to junctions' CE, thus forming an Al/Nb wiring bi-layer. A significant improvement of Jc uniformity on 150-mm wafer has also been obtained along with large improvements in Jc targeting and run-to-run reproducibility.

Feature selection via modified RSBRA for SVM classifiers

Discretization can remove redundant and irrelative attributes during converting continuous attributes into discretized ones and therefore can be used for feature selection. Rough sets and Boolean reasoning based discretization approach (RSBRA), put forward by Nguyen in 1995, is very noticeable for its efficiency of reduction. However, the RSBRA is not a suitable feature selection method for machine learning algorithm such as neural network or SVM because too much useful information are lost due to the discretization. In this paper, we present a modified RSBRA for feature selection and evaluate it with SVM classifiers. In the presented algorithm, the level of consistency, coined from the rough sets theory, is introduced to substitute the stop criterion of circulation of the RSBRA, which maintains the fidelity of the training set after discretization. Experiment results show the modified algorithm has better predictive accuracies and less training time than the original RSBRA.
Association of IFNG gene polymorphism with asthma in the Indian population.

Epidemiologic studies in India show that the prevalence of asthma is increasing, but no genetic studies have been reported on the Indian population thus far. We selected the IFNG locus on 12q21 as a candidate gene for asthma on the basis of its role in pathophysiology and positive linkage demonstrated in other populations. The aim of this study was to investigate association of a CA-repeat marker in this gene with asthma and total serum IgE levels in the North Indian population. The repeat region was PCR-amplified from patients and control subjects and analyzed through use of GeneScan. The distributions of allele sizes were found to be significantly different between patients and control subjects (Kolmogorov-Smirnov test, P < 10(-6)). Alleles 10 and 11 were found to be overrepresented in individuals with asthma, whereas alleles 13 and 15 were less likely in asthmatic individuals. We found that the CA-repeat polymorphism in the IFNG gene was significantly associated with total serum IgE levels (ANOVA, P < 10(-4) for control subjects and P =. 0036 for patients). Furthermore, a previously reported promoter polymorphism at the -333 base pair position was not detected in our population. This is the first report on the association of a candidate gene with asthma from the Indian subcontinent.
Computer-Based Case Simulations for Assessment in Health Care: A Literature Review of Validity Evidence

Simulation for education and training in health-care professions has been widely applied. However, its value as an assessment tool for competence is not fully known. Logistical barriers of simulation-based assessments have led some health-care organizations to utilize computer-based case simulations (CCSs) for assessment. This article provides a review of the literature on the identification of psychometrically sound, CCS instruments designed to measure decision-making competence in health-care professionals. CINAHL, MEDLINE, and Ovid databases identified 84 potentially relevant articles published between January 2000 and May 2017. A total of 12 articles met criteria for inclusion in this review. Findings of these 12 articles indicate that summative assessment in health care using CCSs in the form of clinical scenarios is utilized to assess higher order performance aspects of competence in the form of decision-making. Psychometric strength was validated in eight articles and supported by four replication studies. Two of the eight articles reported evidence of construct validity and support the need for evidence based on a theoretical framework. This literature review offers implications for further research on the use of CCS tools as a method for assessment of competence in health-care professionals and the need for psychometric evidence to support it.
The Opportunistic Reporting of Material Events and the Apparent Misconception of Investors' Reaction

Using a comprehensive sample of non-earnings 8-K filings from 1996 to 2011, we examine whether firms engage in opportunistic reporting of mandatory and voluntary news. We find strong evidence of opportunistic reporting of negative news, especially among public firms. Public firms are more likely to delay disclosure of negative news, report negative news after trading hours, and report on the last day of the week. We also find evidence of opportunistic bundling of news. Our findings support the notion that managers engage in strategic disclosure by delaying or obfuscating negative news in order to mitigate the potential market reaction. Factors such as the risk of litigation, information asymmetry, and corporate governance influence reporting behavior. Further analysis of the market reaction to opportunistic disclosure uncovers no evidence of investor inattention or under-reaction. JEL classifications: G14; G18; K22; M41; M48
Club Sport National Tournament: Economic Impact of a Small Event on a Mid-Size Community

Recreational sporting events are big business and cities throughout the United States are competing fiercely to host events (Saayman, & Saayman, & du Plessis, 2005). March (1984) suggested that the reason why smaller sporting events have received relatively little attention is because it is assumed that they are economically less significant. The purpose of this study was to estimate the economic impact of hosting a club sport national tournament on a midsize community. The current study estimates the economic impact of hosting the American Collegiate Hockey Association (ACHA) Division II National Championship. The survey consisted of 105 questionnaires that were completed during the three day tournament of which all 105 were used. The findings of the survey indicated that hosting a national tournament can have a positive effect on the local economy. It was estimated that nearly $2 million of new money may have been injected into the community of Fort Collins, Colorado. This research provides midsize cities with information to justify hosting one-time events and working favorably with the community university.
CENTER FOR INFORMATION SYSTEMS RESEARCH

Traditionally, most firms' IT capital investment decisions have been based on business cases estimating financial returns on individual applications. Infrastructure costs were often bundled with applications, although disruptive technologies, such as desktop computing and Internet protocols, led to occasional large lump sum investments. In this paper, we argue that firms should make four distinct types of IT investments: transformation, renewal, process improvements, and experiments. Transformation initiatives create significant, long-term infrastructure that enables major changes in organizational processes. Renewal initiatives improve the efficiency or effectiveness of existing shared IT platforms. Business process improvement initiatives increase the net value of business activities, products or services by leveraging, not building, shared infrastructure. Experiments are business applications focused on identifying and developing opportunities afforded by IT. We describe these four types of initiatives and illustrate them using evidence from field research and case studies. We conclude that firms should be investing in all four types of initiatives in order to address both short-term profitability and longer-term survival and growth and to develop the robust IT environment and business applications that are needed to support their desired business model.
Small and Medium Size Enterprises, Credit Supply Shocks, and Economic Recovery in Europe

The limited access to bank credit in recent years has increased the pressure on small and medium size enterprises (SMEs), forcing them to scale down investment plans and production. This paper, which explores the macroeconomic implications of this channel, finds evidence that countries with high prevalence of SMEs tended to recover more slowly from the global financial crisis than their peers, implying that the interaction of the economic structure and access to bank financing plays a critical role in episodes of economic recovery. This conclusion is reinforced by a VAR estimation, which demonstrates that a negative credit supply shock applied to SMEs has an adverse effect on economic activity, and this impact is amplified in countries that have a high share of SMEs.
Primary Pediatric Breast Lesions: Comparing the Prevalence of Malignancies in the Middle East with North America; Review of 1031 Cases

ABSTRACT Benign breast masses are uncommon but are becoming more recognized among the pediatric population. Malignant breast lesions are very rare. The aim of our study was to review and compare the demographics, clinical presentation, treatment, and outcomes of breast lesions, including primary malignancies, and to discuss theories that may explain why there is an increased rate of breast cancers diagnosed at a younger age in the Egyptian population. A total of 1031 cases were reviewed. Comparisons were made between the Egyptian (n = 846) and US (n = 185) cohorts. There were 30 (3.5%) malignant tumors in the Egyptian group with 17 (2%) deaths versus 3 (1.6%) malignant tumors in the US group with 2 (1%) deaths (p = 0.247). The relative risk of breast cancer in the Egyptian group was 2.16 (95% confidence interval (CI): 0.67–7.01) compared with the US group. The trend for increased risk of breast cancer in Egypt may be due to delayed diagnosis because of decreased awareness.
Crystal structures of YBHB and YBCL from Escherichia coli, two bacterial homologues to a Raf kinase inhibitor protein.

In rat and human cells, RKIP (previously known as PEBP) was characterized as an inhibitor of the MEK phosphorylation by Raf-1. In Escherichia coli, the genes ybhb and ybcl possibly encode two RKIP homologues while in the genomes of other bacteria and archaebacteria other homologous genes of RKIP have been found. The parallel between the cellular signaling mechanisms in eukaryotes and prokaryotes suggests that these bacterial proteins could be involved in the regulation of protein phosphorylation by kinases as well. We first showed that the proteins YBHB and YBCL were present in the cytoplasm and periplasm of E. coli, respectively, after which we determined their crystallographic structures. These structures verify that YBHB and YBCL belong to the same structural family as mammalian RKIP/PEBP proteins. The general fold and the anion binding site of these proteins are extremely well conserved between mammals and bacteria and suggest functional similarities. However, the bacterial proteins also exhibit some specific structural features, like a substrate binding pocket formed by the dimerization interface and the absence of cis peptide bonds. This structural variety should correspond to the recognition of multiple cellular partners.
