Determinants of Mobile Banking Adoption in the Ghanaian Banking Industry: A Case of Access Bank Ghana Limited

The study examined the determinant of mobile banking adoption among bank customers in Ghana, with specific emphasis on Access Bank. In line with literature, the study applies theoretical frameworks which have been developed from existing literatures on innovation and adoption to collect responses from one hundred and fifty (150) sampled customers of Access Bank in order to investigate the determinants of mobile banking adoption in the Ghanaian banking industry. The results from the study revealed that, each factor measured had some level of significant effect on consumer intention to adopt and use mobile banking services provided by Access Bank. Additionally, the study unveiled that, perceived credibility and perceived financial cost were the major setback with regards to customers adoption of mobile banking services provided by Access Bank, and as a result of this, Ghanaians have formed a negative behavioural pattern towards mobile banking. In addition, the findings showed that, perceived credibility and perceived financial cost have a stronger effect on consumer intention to adopt and use mobile banking service than perceived usefulness and perceived ease of use. It was, therefore, recommended that banks in Ghana should create more awareness through personal interaction with customers, develop quality initiatives in order to build customer’s confidence. Equally, banks should also review the cost of their mobile banking service.
Dataset and Pipeline for Multi-view Light-Field Video

The quantity and diversity of data in Light-Field videos makes this content valuable for many applications such as mixed and augmented reality or post-production in the movie industry. Some of such applications require a large parallax between the different views of the Light-Field, making the multi-view capture a better option than plenoptic cameras. In this paper we propose a dataset and a complete pipeline for Light-Field video. The proposed algorithms are specially tailored to process sparse and wide-baseline multi-view videos captured with a camera rig. Our pipeline includes algorithms such as geometric calibration, color homogenization, view pseudo-rectification and depth estimation. Such elemental algorithms are well known by the state-of-the-art but they must achieve high accuracy to guarantee the success of other algorithms using our data. Along this paper, we publish our Light-Field video dataset that we believe may be of special interest for the community. We provide the original sequences, the calibration parameters and the pseudo-rectified views. Finally, we propose a depth-based rendering algorithm for Dynamic Perspective Rendering.
Antigenic Competition: Cellular or Humoral

The injection of one antigen into mice inhibited the response to a second when 1 to 10 days separated the two injections. When the same type of inhibition was attempted in γ-irradiated mice reconstituted with normal spleen cells, the inhibition was greater in mice receiving 50 million spleen cells than in those receiving 10 million. The results are interpreted as favoring a humoral mechanism of inhibition.

Ampacity derating factors for cables buried in short segments of conduit

Buried cables are often routed through short segments of conduit, and when this situation occurs, the ampacity must be reduced or the cable will overheat as a result of the high thermal resistance created at the location of the conduit. This problem is examined for extruded cables by using a finite element heat transfer software program to determine the derating in ampacity that cables in conduits must experience in order to remain below a maximum conductor temperature. The derating factors are provided as a function of conduit length, soil resistivity, burial depth and number of cables in the conduit. The results show that once the length of conduit exceeds about 20 times its outer diameter, then the ampacity of the circuit must be reduced to the value that it would have if the entire length were buried in the conduit. Factors that result in lower cable ampacities, such as high soil thermal resistivity and deeper burial depths lead to larger derating factors.
Dyskinesia and parkinsonism in antipsychotic-naive patients with schizophrenia, first-degree relatives and healthy controls: a meta-analysis.

BACKGROUND Several studies have reported the presence of dyskinesia and parkinsonism in antipsychotic-naive patients with schizophrenia as well as in their first-degree relatives. These movement disorders may therefore form an integral part of the illness and its (genetic) liability. METHOD A systematic search was conducted in the Medline, EMBASE, and PsychINFO databases to identify studies reporting on dyskinesia and parkinsonism assessed in antipsychotic-naive patients with schizophrenia (n = 213) and controls (n = 242) and separately in nonill first-degree relatives (n = 395) and controls (n = 379). Effect sizes were pooled using random-effect models to calculate odds ratios (ORs) to compare the risk of these movement disorders among patients and healthy relatives each with matched controls. RESULTS Antipsychotic-naive schizophrenia was found to be strongly associated with dyskinesia (OR: 3.59, 95% confidence interval [CI]: 1.53-8.41) and parkinsonism (OR: 5.32, 95% CI: 1.75-16.23) compared with controls. Dyskinesia and parkinsonism were also significantly more prevalent in healthy first-degree relatives of patients with schizophrenia as compared with healthy controls (OR: 1.38, 95% CI: 1.06-1.81, and OR: 1.37, 95% CI: 1.05-1.79, respectively). CONCLUSION The results suggest that movement disorders, and by inference abnormalities in the nigrostriatal pathway, are not only associated with schizophrenia itself but may also be related to the (genetic) risk of developing the disease.
Comparison of Transradial and Transfemoral Approaches in Women Undergoing Percutaneous Coronary Intervention in China: A Retrospective Observational Study

Despite increasing adoption of the transradial approach for percutaneous coronary intervention (PCI) in clinical practice, the role of transradial intervention (TRI) in women remains a significant debate. We identified 1392 women from a consecutive cohort of patients undergoing PCI in China in 2010 and compared the efficacy and hospital costs between TRI and transfemoral intervention. An inverse probability weighting (IPW) method was used to control for potential bias. After IPW adjustment, patients receiving TRI were less likely to experience post-PCI bleeding (adjusted odds ratio [OR]: 0.46, 95% confidence interval [CI]: 0.30-0.71) and major adverse cardiac events (adjusted OR 0.35, 95% CI 0.19-0.63) and more likely to have shorter length of stay in hospital (1.2 days difference, 95% CI: 0.6-1.7). Moreover, TRI was associated with a cost saving of ¥ (Yuan Renminbi) 7474 (approximately US$1150, 95% CI: ¥2993-¥11 624). More than 70% of this saving was driven by lower PCI-related costs. In conclusion, the use of TRI in women was associated with more favorable outcomes and lower hospital costs.
Analysis of prognostic factors in Ewing sarcoma using a population‐based cancer registry

Ewing sarcoma is a high‐grade malignancy that most often occurs in children. Because its occurrence in adults has been historically low, few studies have been published on the epidemiology of Ewing sarcoma in this group of patients. By using data from a large, population‐based cancer registry, the authors designed the present study to examine the outcome of children and adult patients with Ewing sarcoma and relevant prognostic factors.
Mechanisms of health behavior change in persons with chronic illness or disability: the Health Action Process Approach (HAPA).

OBJECTIVE The present article presents an overview of theoretical constructs and mechanisms of health behavior change that have been found useful in research on people with chronic illness and disability. A self-regulation framework (Health Action Process Approach) serves as a backdrop, making a distinction between goal setting and goal pursuit. Risk perception, outcome expectancies, and task self-efficacy are seen as predisposing factors in the goal-setting (motivational) phase, whereas planning, action control, and maintenance/recovery self-efficacy are regarded as being influential in the subsequent goal-pursuit (volitional) phase. The first phase leads to forming an intention, and the second to actual behavior change. Such a mediator model serves to explain social-cognitive processes in health behavior change. By adding a second layer, a moderator model is provided in which three stages are distinguished to segment the audience for tailored interventions. Identifying persons as preintenders, intenders, or actors offers an opportunity to match theory-based treatments to specific target groups. Numerous research and assessment examples, especially within the physical activity domain, serve to illustrate the application of the model to rehabilitation settings and health promotion for people with chronic illness or disability. CONCLUSIONS/IMPLICATIONS The theoretical developments and research evidence for the self-regulation framework explain the cognitive mechanisms of behavior change and adherence to treatment in the rehabilitation setting.
Public health policies and management strategies for genital Chlamydia trachomatis infection

Genital Chlamydia trachomatis is a sexually transmissible bacterial infection that is asymptomatic in the majority of infected individuals and is associated with significant short-term and long-term morbidity. The population prevalence of the infection appears to be increasing. C. trachomatis is of public health significance because of the impacts of untreated disease on reproductive outcomes, transmission of other sexually acquired infections, and the costs to health systems. At the individual level, C. trachomatis infection is readily treatable with antibiotics, although antibiotic resistance appears to be increasing. At the population level, public health control of spread of infection is more problematic. Approaches to control include primary preventive activities, increased access to testing and treatment for people with or at risk of infection, partner notification and treatment, and screening either opportunistically or as part of an organized population screening program. A combination of all of the above approaches is likely to be required to have a significant effect on the burden of disease associated with genital chlamdyia infection and to reduce population prevalence. The development of a vaccine for genital chlamydia infection could significantly reduce the public health burden associated with infection; however a vaccine is not expected to be available in the near future.
A non-extraction atomic absorption method for the determination of lead in blood.

A routine method for atomic absorption analysis of lead in blood is described, which does not involve solvent extraction of the metal. Proteins are precipitated by trichloroacetic acid in the presence of perchloric acid, the sample centrifuged and the supernatant liquid analysed directly. The results obtained are in good agreement with those obtained either on completely ashed blood or on ammonium pyrrolidine dithiocarbamate extracted blood. The speed of analysis is much greater than for the extraction method, and the sensitivity sufficient even for normal blood lead levels.
Tightly coupled long baseline/ultra-short baseline integrated navigation system

This paper proposes a novel integrated navigation filter based on a combined long baseline/ultra short baseline acoustic positioning system with application to underwater vehicles. With a tightly coupled structure, the position, linear velocity, attitude, and rate gyro bias are estimated, considering the full nonlinear system dynamics without resorting to any algebraic inversion or linearisation techniques. The resulting solution ensures convergence of the estimation error to zero for all initial conditions, exponentially fast. Finally, it is shown, under simulation environment, that the filter achieves very good performance in the presence of sensor noise.
Efficient Spin Detection Across the Hybrid Co/GaAs Schottky Interface

The electron spin detection efficiency was studied across Co/GaAs structures using photoexcitation techniques. Two sets of samples were prepared where the substrate surface was pretreated by annealing prior to growth for the first set whereas for the second no annealing treatment was carried out. While, in the annealed sample, spin detection was observed, the nonannealed case showed no spin-dependent transport effects. This is attributed to the absence of a Schottky tunnel barrier to facilitate tunnelling through the interface, as the transport mechanism responsible for the spin filtering. Furthermore, it illustrates the influence of the interface quality on spin dependent transport processes for the general case of any FM electrode
Fast Source Camera Identification Using Content Adaptive Guided Image Filter

Source camera identification (SCI) is an important topic in image forensics. One of the most effective fingerprints for linking an image to its source camera is the sensor pattern noise, which is estimated as the difference between the content and its denoised version. It is widely believed that the performance of the sensor‐based SCI heavily relies on the denoising filter used. This study proposes a novel sensor‐based SCI method using content adaptive guided image filter (CAGIF). Thanks to the low complexity nature of the CAGIF, the proposed method is much faster than the state‐of‐the‐art methods, which is a big advantage considering the potential real‐time application of SCI. Despite the advantage of speed, experimental results also show that the proposed method can achieve comparable or better performance than the state‐of‐the‐art methods in terms of accuracy.
Raman scattering and electron-phonon coupling in RbxC60.

{ital In} {ital situ}, interference-enhanced Raman scattering of ultrathin, solid solution films of Rb{sub {ital x}}C{sub 60} (0{le}{ital x}{le}3) prepared in UHV are reported. Variations of phonon linewidths of both selected low-frequency, radial and high-frequency, tangential intramolecular modes indicate strong electron-phonon coupling. The results directly support a recent theory for phonon-mediated superconductivity in alkali-C{sub 60} systems.
Variable speed wind turbines capability for temporary over-production

New control systems for Variable Speed Wind Turbines (VSWT) need to be developed in order to provide inertia response and frequency control to support the grid. This work studies the behavior and capability of VSWT for providing temporary active power overproduction. The study is conducted on a multi-megawatt VSWT with Doubly-Fed Induction Generator. It was found that it is possible to have an active power overproduction of 0.2 pu for at least 10 seconds, which could be useful for the grid operator for restoring a critical situation of grid frequency dip. Nevertheless it is important to be aware about the underproduction power and the associated recovery period that follow a VSWT overproduction operation. The results can be used in designing suitable control systems for VSWT inertia response and frequency control.
Familial aggregation of atrial fibrillation in Iceland.

AIMS To examine the heritability of atrial fibrillation (AF) in Icelanders, utilizing a nationwide genealogy database and population-based data on AF. AF is a disorder with a high prevalence, which has been known to cluster in families, but the heritability of the common form has not been well defined. METHODS AND RESULTS The study population included 5269 patients diagnosed since 1987 and age-sex-matched controls randomly selected from the genealogy database. Kinship coefficients (KC), expressed as genealogical index of familiality (GIF = average KC x 100,000), were calculated before and after exclusion of relatives separated by one to five meiotic events. Risk ratios (RR) were calculated for first- to fifth-degree relatives. The average pairwise GIF among patients with AF was 15.9 (mean GIF for controls 13.9, 95%CI = 13.3, 14.4); this declined to 15.4 (mean GIF for controls 13.6, 95%CI = 13.1, 14.2) after exclusion of relatives separated by one meiosis and to 13.7 (mean GIF for controls 12.6, 95%CI = 12.1, 13.2), 12.7 (mean GIF for controls 11.9, 95%CI = 11.4, 12.4), and 11.3 (mean GIF for controls 10.6, 95%CI = 10.1, 11.1) after exclusion of relatives within two, three, and four meioses, respectively (all P<0.00001). RRs among relative pairs also declined incrementally, from 1.77 in first-degree relatives to 1.36, 1.18, 1.10, and 1.05 in second- through fifth-degree relatives (all P<0.001), consistent with the declining proportion of alleles shared identically by descent. When the analysis was limited to subjects diagnosed with AF before the age of 60, first-degree relatives of the AF cases were nearly five times more likely to have AF than the general population. CONCLUSION AF shows strong evidence of heritability among unselected patients in Iceland, suggesting that there may be undiscovered genetic variants underlying the risk of the common form of AF.
γδ T cell receptor repertoire in blood and colonic mucosa of rhesus macaques

Although their precise roles are not well defined, γδ T lymphocytes are recognized as regular components of immune responses. These cells express a limited T cell receptor repertoire and they can be stimulated by soluble ligands without conventional processing and presentation by major histocompatibility antigens. Progress in this area has been limited by the substantial differences between murine and human γδ T cells and the lack of knowledge about these cells in nonhuman primates. We used molecular analysis of T cell receptor diversity to characterize γδ T cell populations from peripheral blood and colon of rhesus macaques (Macaca mulatta). The γδ T cell receptor diversity was limited and distinct for these tissue compartments, particularly in the TCRGV2 family. Furthermore, the TCRDV1+ subset of peripheral blood γδ T cells showed signs of progressive oligoclonalization as a function of age. Similar observations have been reported for human tissue samples and our results validate rhesus macaques as an appropriate animal model for studying primate γδ T cell populations.
Comparison of student performance in cooperative learning and traditional lecture‐based biochemistry classes

Student performance in two different introductory biochemistry curricula are compared based on standardized testing of student content knowledge, problem‐solving skills, and student opinions about the courses. One curriculum was used in four traditional, lecture‐based classes (n = 381 students), whereas the second curriculum was used in two cooperative learning classes (n = 39 students). Students in the cooperative learning classes not only performed at a level above their peers in standardized testing of content knowledge and in critical thinking and problem‐solving tasks (p < 0.05), but they also were more positive about their learning experience. The testing data are in contrast to much of the medical school literature on the performance of students in problem‐based learning (PBL) curricula, which shows little effect of the curricular format on student exam scores. The reason for the improvement is undoubtedly multifactorial. We argue that the enhancement of student performance in this study is related to: 1) the use of peer educational assistants, 2) an authentic PBL format, and 3) the application of a multicontextual learning environment in the curricular design. Though educationally successful, the cooperative learning classes as described in this study were too resource intensive to continue; however, we are exploring incorporation of some of the “high context” aspects of the small‐group interactions into our current lecture‐based course with the addition of on‐line PBL cases.
The Adequate Use of Limited Information in Dispersal Decisions

Several theoretical studies predict that informed (e.g., density-dependent) dispersal should generally result in lower emigration probabilities than uninformed (random) dispersal. In a 2012 publication, Bocedi et al. surprisingly come to the opposite conclusion. For most scenarios investigated, they found that noninformed and, particularly, less precisely informed dispersers evolve lower dispersal propensity than dispersers following “fully informed” strategies. Further, they observed that fully informed individuals evolved a steplike dispersal response—a response to local density that contradicts theoretical predictions for organisms with nonoverlapping generations. Replicating the individual-based simulations of Bocedi et al. we find that these conclusions are not justified and are based on a misinterpretation of simulation results: their controversial findings result from (i) a misleading use of the term “population density,” (ii) a misconception concerning the true informative value of the different decision criteria they compared, and (iii) arbitrary constraints on the evolution of the dispersal response that prevented the evolution of strategies that allow for a fitness-enhancing utilization of available information.
