Internet banking: an initial look at Ghanaian Bank Consumer Perceptions

Internet banking is a tool in the service delivery arsenal for banks. This study focuses on client-bank relationship and on how Internet adoption may improve the qualitative relationship between banks and firms in Ghana and the business they serve. The study adopted a triangulation approach in meeting its objectives. A sample of 180 companies was sampled from the manufacturing, commerce, and services sectors of the economy. The findings of the study were mainly reported by means of descriptive statistics. The research findings indicate that Internet banking services are at their infant stage. Of the respondents, 68% had heard about Internet banking while 33% have never heard about it. 55% of the respondents said security concerns were the major barrier to the adoption of Internet banking. 55.6% of the firms that responded were not connected to the Internet whiles 44.4% were. Majority of the interviewees said they would still visit the bank even if their company adopts Internet banking. Access to their account balance and understanding customer needs are the most important factors for facilitating a good bank client relationship for firms in Ghana and their banks. Banks in Ghana need to start considering the introduction of Internet strategies in the development of customer relationship management (CRM) programs, which will ultimately increase the customer lifetime value of their clients. The present paper is one of the first Internet banking studies from a West African context on the usefulness of Internet banking technologies to bank clients.
Usage and Gratification of Social Media in Higher Education: A Survey on the Perceptions of International Students in Turkey

This study grounded in the user centered media theory of uses and gratification; it investigated on the usage and gratification of social media among international students pursuing higher education in Turkey, through a survey conducted on a sample of international students in Istanbul City, Turkey. The study was quantitative in nature in which structured questionnaires were used to get data on a randomly selected sample. Findings indicate that 68.2% of the respondents used social media for more than twice a week to interact with peers for studying outside classroom. Likewise, social media platform commonly used included YouTube, Facebook, WhatsApp, Google group and Twitter. As a gratification, the respondents used You Tube to watch educational video clips on lectures delivered from other universities, watched Turkish videos to improve on their Turkish language skills. Facebook and Whatsapp were used for instant messaging, sharing academic information with classmates and professors. Findings indicate that using Social Media positively influenced their lifestyles and helped them to excel academically as reflected in the responses. The study therefore concludes that Social Media is an essential communication tool among international students in Turkey in supporting their higher education.
Virtual Reality in Psychiatry

Virtual Reality in the field of medicine is making a considerable progress in psychiatry. Virtual reality exposure therapy (VRET) in particular can serve as a preferable solution for PTSD (Post-Traumatic Stress disorder) patients who avoids or finds retrieving image difficult. Relevant studies were reviewed to identify the pros and cons of virtual reality technology applied to psychiatry and to determine its medical effect.
Coverage control in non-convex environment considering unknown non-convex obstacles

This paper presents a cooperative algorithm by which a group of mobile robots cover an unknown non-convex environment in the presence of unknown obstacles. Each one starts from a random position and navigates to cover area while avoiding collisions with the fixed-obstacles exist in the field. Moreover, convergence to the maximal coverage is studied. Comparing with the previous algorithms, the proposed approach is able to deal with non-convex domains considering non-convex obstacles, covers more areas with limited sensing and save more energy in non-convex domains. Simulation results validate the enhanced performance of the proposed approach.
Symptomatic and Asymptomatic Rotavirus and Norovirus Infections During Infancy in a Chilean Birth Cohort

Background: Rotavirus and more recently norovirus have been recognized as 2 of the most common causes of acute diarrhea in children. Comparative analysis of these infections in a birth cohort has not been performed and can provide relevant insight on clinical and viral behaviors. Methods: Mother-infant pairs from middle-low socioeconomic background living in the Metropolitan Region of Chile are being followed for 18 months in 2 outpatient clinics. Infants are evaluated monthly for asymptomatic excretion of rotavirus and norovirus and during acute diarrhea episodes (ADE) for rotavirus, norovirus, and bacterial enteropathogens. Severity of ADE is evaluated using the Vesikari score. Results: Between July 1, 2006 and September 1, 2008 a total of 198 children were followed for a mean of 15.7 months. Asymptomatic rotavirus and norovirus infections were detected in 1.3% and 8% of 2278 stool samples compromising 14% and 57% of infants, respectively. Incidence of ADE was approximately 0.8 for the first year of life and approximately 0.6 for the 13 to 18 month age group. Rotavirus and norovirus were detected in 15% and 18% of 145 ADE evaluated. Mean Vesikari score was 10.4 and 7.4 for rotavirus and norovirus respectively (P = 0.01) and severity was not associated with age of patients for either virus. Reinfections were more common for norovirus asymptomatic episodes: 44% versus 19% (P = 0.01) and borderline for symptomatic episodes: 40% versus 11% (P = 0.08). Rotavirus genotype G9P8 and norovirus genogroup II (GII) predominated although most asymptomatic episodes for both viruses were nontypable. None of 19 symptomatic GII norovirus infections had a previous documented GII infection compared with 10 of 31 asymptomatic GII infections (OR = 0. 95% CL = 0, 0.59; P = 0.008). Conclusions: Children had suffered a mean of approximately 1.4 ADE by 18 months of age of which 15% and 18% were caused by rotavirus and norovirus, respectively. In general rotavirus infections were more severe than norovirus infections and for both viruses severity was not related to age. Norovirus reinfections were significantly more common than rotavirus reinfections but for GII norovirus a primary infection seems to confer protection against clinically significant reinfections.
MiR-199a-5p and let-7c cooperatively inhibit migration and invasion by targeting MAP4K3 in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) has a high recurrence rate, and patients exhibit poor survival mainly because intrahepatic metastasis is common. We previously reported that let-7c down-regulation is significantly associated with poor differentiation level in HCC. In the present study, we demonstrate that miR-199a-5p and let-7c are frequently down-regulated in HCC cells and tissues, and low expression of miR-199a-5p is correlated with tumor size, liver envelope invasion. Furthermore, miR-199a-5p and let-7c cooperatively inhibit HCC cell migration and invasion in vitro. MAP4K3 is identified as the direct target of miR-199a-5p and let-7c and this regulation is further confirmed by luciferase reporter assays and Western blotting. In addition, MAP4K3 functions as a metastasis promoter since the results demonstrate that MAP4K3 could promote HCC cell migration and invasion. We also find that miR-199a-5p and let-7c increase the sensitivity of HCC cells to sorafenib. Conclusions We report that miR-199a-5p and let-7c cooperatively and efficiently inhibit HCC cell migration and invasion by targeting the metastasis promoter MAP4K3 and MAP4K3-mediated drug sensitization, suggesting that the use of miRNAs and sorafenib in combination therapy may be a powerful approach to the treatment of HCC.
Nuclear and Mitochondrial DNA Alterations in Newborns with Prenatal Exposure to Cigarette Smoke

Newborns exposed to maternal cigarette smoke (CS) in utero have an increased risk of developing chronic diseases, cancer, and acquiring decreased cognitive function in adulthood. Although the literature reports many deleterious effects associated with maternal cigarette smoking on the fetus, the molecular alterations and mechanisms of action are not yet clear. Smoking may act directly on nuclear DNA by inducing mutations or epigenetic modifications. Recent studies also indicate that smoking may act on mitochondrial DNA by inducing a change in the number of copies to make up for the damage caused by smoking on the respiratory chain and lack of energy. In addition, individual genetic susceptibility plays a significant role in determining the effects of smoking during development. Furthermore, prior exposure of paternal and maternal gametes to cigarette smoke may affect the health of the developing individual, not only the in utero exposure. This review examines the genetic and epigenetic alterations in nuclear and mitochondrial DNA associated with smoke exposure during the most sensitive periods of development (prior to conception, prenatal and early postnatal) and assesses how such changes may have consequences for both fetal growth and development.
Inaccuracy and Bias in Textbooks Reporting Psychiatric Research: The Case of the Schizophrenia Adoption Studies

Mental health textbooks sometimes provide inaccurate information, typically supporting common beliefs in the field. Psychiatry and psychology textbooks' discussion of the schizophrenia adoption studies is examined. Particular attention is paid to the earlier studies, which helped pave the way for the current widespread acceptance of the importance of genetic factors influencing psychological trait differences. This article compares the accounts of 30 textbooks to the original studies they reviewed. Generally, problems with these textbooks' accounts include (1) the failure to critically assess the original researchers' methods and conclusions, (2) some textbooks' reliance on secondary sources, (3) the failure to discuss published critiques of the schizophrenia adoption studies, (4) inaccuracy in reporting the original findings, (5) the claim that studies finding nonsignificant results support the genetic position, and (6) a failure to discuss the potentially invalidating environmental confounds in the schizophrenia adoption studies (through the selective placement of adoptees). It is concluded that, in general, these textbooks have served to rubber-stamp mainstream psychiatry's questionable claims about the schizophrenia adoption studies at the expense of a thorough critical analysis.
The Pratt Pouch Provides a Three-Fold Access Increase to Antiretroviral Medication for Births outside Health Facilities in Southern Zambia

Introduction: Modern day antiretroviral therapy allows HIV+ pregnant women to lower the likelihood of viral transmission to their infants before, during, and after birth from 20-45% to less than 5%. In developing countries, where non-facility births may outnumber facility births, infant access to safe antiretroviral medication during the critical first three days after birth is often limited. A single-dose, polyethylene pouch (“Pratt Pouch”) addresses this challenge by allowing the medication to be distributed to mothers during antenatal care. Methods: The Pratt Pouch was introduced as part of a one year clinical feasibility study in two districts in Southern Province, Zambia. Participating nurses, community health workers, and pharmacists were trained before implementation. Success in achieving improved antiretroviral medication access was assessed via pre intervention and post intervention survey responses by HIV+ mothers. Results: Access to medication for HIV-exposed infants born outside of a health facility increased from 35% (17/51) before the introduction of the pouch to 94% (15/16) after (p<0.05). A non-significant increase in homebirth rates from 33% (pre intervention cohort) to 50% (post intervention cohort) was observed (p>0.05). Results remained below the national average homebirth rate of 52%. Users reported minimal spillage and a high level of satisfaction with the Pratt Pouch. Conclusion: The Pratt Pouch enhances access to infant antiretroviral medication in a rural, non-facility birth setting. Wide scale implementation could have a substantial global impact on HIV transmission rates from mother to child.
BMC Medical Informatics and Decision Making

Background: Systematic reviews or randomised-controlled trials usually help to establish the effectiveness of drugs and other health technologies, but are rarely sufficient by themselves to ensure actual clinical use of the technology. The process from innovation to routine clinical use is complex. Numerous computerised decision support systems (DSS) have been developed, but many fail to be taken up into actual use. Some developers construct technologically advanced systems with little relevance to the real world. Others did not determine whether a clinical need exists. With NHS investing £5 billion in computer systems, also occurring in other countries, there is an urgent need to shift from a technology-driven approach to one that identifies and employs the most cost-effective method to manage knowledge, regardless of the technology. The generic term, 'decision tool' (DT), is therefore suggested to demonstrate that these aids, which seem different technically, are conceptually the same from a clinical viewpoint. Discussion: Many computerised DSSs failed for various reasons, for example, they were not based on best available knowledge; there was insufficient emphasis on their need for high quality clinical data; their development was technology-led; or evaluation methods were misapplied. We argue that DSSs and other computer-based, paper-based and even mechanical decision aids are members of a wider family of decision tools. A DT is an active knowledge resource that uses patient data to generate case specific advice, which supports decision making about individual patients by health professionals, the patients themselves or others concerned about them. The identification of DTs as a consistent and important category of
Weak if any effect of estrogen on spatial memory in rats

In a number of species, males appear to have spatial abilities that are superior to those of females. The favored explanation for this cognitive difference is hormonal: higher testosterone levels in males than in females. An alternative explanation focuses on the role of varying levels of estrogens in females during the estrus cycle; females perform as well as males on days of low estrogen, but more poorly on days of high estrogen. Other investigators have reported that estrogens improve both types of memory processes, which depend on the striatal (nonspatial navigation) and hippocampal (spatial) memory systems. Additionally, estrogens have been found to protect the working memory. These contradictory results initiated the present study, in which ovariectomized female rats were trained to escape in a Morris water maze. The daily trials were preceded by estradiol application in low doses (Experiment I) or in higher doses (Experiment II). In Experiment I, no differences at all were found between the latencies of the treated and control groups to reach a submerged platform in a Morris water maze. In Experiment II, however, the animals treated with the higher dose of estradiol showed a small deficit in the acquisition of the Morris water maze task. This study indicates that estradiol at around the physiological level has no effect on spatial learning and memory functions. + Dedicated to Professor Otto Feher on the occasion of his 75 th birthday.
The geographical digital divide in broadband access and governmental policies in Japan: three case studies

Broadband access is indispensable for advanced Internet services, because voluminous data transfers have recently become popular in developed societies. Although broadband access has spread to a certain degree in developed countries/regions, geographical gaps in broadband access (the so-called “geographical digital divide”) remain. Based on three case studies in less-favoured areas of Japan (Hokkaido, Nagano Prefecture and Mie Prefecture), we examined how the geographical digital divide is being bridged, and the contributions that national and local government policies make to this process. Several implications were apparent. First, integrating communication infrastructures with manifold digital services, such as cable television services and broadband access, is an effective way to extend broadband to less-favoured areas. The Japanese government has promoted the construction of digital cable television networks, and they have played a significant role in the completion of universal broadband services. The challenge of digitizing terrestrial television broadcasting has been behind these policies. Another effective means of extending broadband has been the pressure exerted by local governments (under the national policy scheme) on private cable television companies to bring their services to even the least populated regions. Finally, in those areas where private digital network services are unprofitable, the establishment of a publicly funded cable business (using a budget-transfer scheme, for example) may be an effective option for extending broadband services. In general, the challenge of bridging the geographical digital divide should be tackled with a broad set of regional promotion policies for less-favoured regions.
Clinicopathological and prognostic significance of regulatory T cells in patients with non-small cell lung cancer: A systematic review with meta-analysis

The prognostic and clinicopathological value of regulatory T cells (Tregs) infiltration in patients with non-small cell lung cancer (NSCLC) remains undetermined. A comprehensive literature search of electronic databases (up to December 2015) was conducted. Relationship between Tregs infiltration and clinicopathological features, recurrence-free survival (RFS) and overall survival (OS) was investigated by synthesizing the qualified data. A total of 1303 NSCLC patients from 11 studies were included. The pooled hazard ratio (HR) for survival showed that high Tregs infiltration had no effect on RFS (HR = 2.03, 95% CI: 0.61–3.44, P = 0.708) and OS (HR = 1.20, 95% CI: 0.58–1.62, P = 0.981). High FoxP3+ Tregs infiltration was significantly associated with poor OS in NSCLC (HR = 3.88, 95% CI: 2.45–5.40, P = 0.000). Test methods, ethnicity and types of specimens had no effect on predicting prognosis of Tregs infiltration. While high Tregs infiltration was significantly correlated with smoking status [odds ratios (ORs) = 1.54, 95% CI: 1.15–2.08; P = 0.004], none of other clinicopathological characteristics such as gender, histological type, lymph node metastasis status, tumor size, vascular invasion, lymphatic invasion and pleural invasion were associated with Tregs infiltration. The present study demonstrated that high FoxP3+ Tregs infiltration was significantly associated with poor prognosis in NSCLC and smoking status.
Estimating Residential Electricity Demand Under Declining-Block Tariffs

A disaggregated economic study of 3825 geographic areas of Los Angeles County was used to estimate electricity demand under declining-block rates. Micro-level data were collected on the marginal price of households, the control of eight major appliances, and weather variables. Several biases are noted, but demand theory under declining-block rates is confirmed. The results are given in terms of short- and long-run changes and income elasticities. 15 references, 5 figures, 3 tables. (DCK)
Evidence for conditional sex differences in emotional but not in sexual jealousy at the automatic level of cognitive processing

The two evolutionary psychological hypotheses that men react more jealous than women to sexual infidelity and women react more jealous than men to emotional infidelity are currently controversial because of apparently inconsistent results. We suggest that these inconsistencies can be resolved when the two hypotheses are evaluated separately and when the underlying cognitive processes are considered. We studied jealousy with forced‐choice decisions and emotion ratings in a general population sample of 284 adults aged 20–30 years using six infidelity dilemmas and recordings of reaction times. The sex difference for emotional jealousy existed for decisions under cognitive constraint, was also evident in the decision speed, increased for faster decisions, and was stronger for participants with lower education. No evidence for a sex difference in sexual jealousy was found. Our results support the view of a specific female sensitivity to emotional infidelity that canalizes the development of an adaptive sex difference in emotional jealousy conditional to the sociocultural environment.

Distributed under Creative Commons Cc-by 4.0 Life History and past Demography Maintain Genetic Structure, Outcrossing Rate, Contemporary Pollen Gene Flow of an Understory Herb in a Highly Fragmented Rainforest

Introduction. Theory predicts that habitat fragmentation, by reducing population size and increasing isolation among remnant populations, can alter their genetic diversity and structure. A cascade of effects is expected: genetic drift and inbreeding after a population bottleneck, changes in biotic interactions that may affect, as in the case of plants, pollen dynamics, mating system, reproductive success. The detection of the effects of contemporary habitat fragmentation on the genetic structure of populations are conditioned by the magnitude of change, given the few number of generations since the onset of fragmentation, especially for long-lived organisms. However, the present-day genetic structure of populations may bear the signature of past demography events. Here, we examine the effects of rainforest fragmentation on the genetic diversity, population structure, mating system (outcrossing rate), indirect gene flow and contemporary pollen dynamics in the understory herb Aphelandra aurantiaca. Also, we assessed its present-day genetic structure under different past demographic scenarios. Methods. Twelve populations of A. aurantiaca were sampled in large (4), medium (3), and small (5) forest fragments in the lowland tropical rainforest at Los Tuxtlas region. Variation at 11 microsatellite loci was assessed in 28–30 reproductive plants per population. In two medium-and two large-size fragments we estimated the density of reproductive plants, and the mating system by analyzing the progeny of different mother plants per population. Results. Despite prevailing habitat fragmentation, populations of A. aurantiaca possess high genetic variation (H e = 0.61), weak genetic structure (R st = 0.037), and slight inbreeding in small fragments. Effective population sizes (N e) were large, but slightly lower in small fragments. Migrants derive mostly from large and medium size fragments. Gene dispersal is highly restricted but long distance gene dispersal events were detected. Aphelandra aurantiaca shows a mixed mating system (t m = 0.81) and the outcrossing rate have not been affected by habitat fragmentation. A strong pollen pool structure was detected due to few effective pollen donors (N ep) and low distance pollen movement, pointing that most plants received pollen from close neighbors. Past demographic fluctuations may have affected the present population genetic structure
