Assessment on Use of Search Engines by Lecturers in the Faculty of Medical Sciences, University of Jos, Nigeria

Purpose: This research investigated the Internet Search Engine use behaviour of lecturers in the Faculty of Medical Sciences, University of Jos. Design/Methodology/Approach: The study adopted the survey research design. The entire population of 133 academic staff members in the Faculty was adopted for the research. Descriptive survey was the research method used for the study. The instrument used for data collection was questionnaire. Descriptive statistics such as frequency counts and percentages were used to analyze the data. Findings: The findings revealed among others that Google was the most popular search engine amongst the lecturers. However, the academics admitted that they learned how to use the search engines through seminars and workshops organized by the University management. The findings further revealed that only few of the lecturers were aware of the Advanced and Boolean Search Options provided by the engines, the lecturers also indicated that coping with too much information hits was their major problem in using the search engines. Implication: More sensitization is needed for the lecturers. Originality/Value: The University Management through the Directorate of Information and Communication Technology (ICT) Unit in association with the University Library should continue to organize workshops and seminars for the lecturers on how to use the various search engines to effectively access information in the internet.
Changes in Fog, Ice Fog, and Low Visibility in the Hudson Bay Region: Impacts on Aviation

Fog and low visibility present a natural hazard for aviation in the Hudson Bay region. Sixteen communities on the eastern and western shores of Hudson and James Bays, Canada, were selected for fog, ice fog, and low visibility statistical analyses for a range of 21 to 62 year time series. Both fog hours and ice fog hours were found to be in general decline, with some locations experiencing statistically significant declines. Spatial asymmetries for fog and ice fog were observed among the various areas within the Hudson Bay region. The more northerly locations in this study experienced statistically significant declines in fog hours while the southerly locations’ declines were not significant. Fog was significantly declining in some western Hudson Bay locations during spring and fall and in James Bay during winter and summer, but minimal trends were observed in eastern Hudson Bay. For ice fog hours, all of the locations in the western shore of Hudson Bay experienced a significant decline in winter while only one-third of the locations in eastern shores were found to be declining significantly during winter. Blowing snow, snow, ice and fog were the leading causes for reduced and low visibilities at the majority of the locations. Other factors such as rain contributed a minor role to low visibility.
Outcome of conservative and surgical management of displaced intra-articular calcaneal fractures: Original article

Introduction: A calcaneal fracture is a break of the calcaneus. Symptoms may include pain, bruising, trouble walking, and deformity of the heel. It may be associated with breaks of the hip or back. It usually occurs when a person lands on their feet following a fall from a height or during a motor vehicle collision. Diagnosis is suspected based on symptoms and confirmed by X-rays or CT scan. If the bones remain normally aligned treatment may be by casting without weight bearing for around eight weeks. If the bones are not properly aligned surgery is generally required. Materials and Methods: This is a prospective study of 20 cases of displaced intra-articular calcaneal fractures managed both surgically and conservatively. Patients were selected according to inclusion and exclusion criteria mentioned below.10 patients were treated surgically and 10 patients who were not willing for surgery were treated conservatively after taking proper consent. Results: The mean age was 26.5 years (10-49), 40% of the cases were in the age group of 20-29 in conservative whereas surgical cases constitutes of 43% (20-29) with the mean age of 26.88. Mode of injury was fall from height in 100% of cases in conservative whereas in surgical 90% cases are in fall from height and rest 10% can be seen in road traffic accident. In conservative 20% of results were excellent, 70% were good and 10% of the cases were fair. Whereas in surgical 60% of the cases were excellent and 40% were good. Occupational rehabilitation to the patient‘s pre injury state was achieved in 60% of cases in conservative and 90% of cases in surgical. Conclusion: Intra articular calcaneal fractures are better managed surgically compared to conservative management by understanding the fracture anatomy and restoration of Bohler‘s angle and angle of Gissane. Delayed surgical intervention had better results than early intervention for surgery.
Does nomination influence women’s access to institutional decision-making bodies?

Based in CHANGE, a H2020 funded project, this paper puts in perspective the reality of a Portuguese university in terms of gender representation in its governance and management bodies. Portuguese higher education institutions (HEI) are excellent case-studies of women representation in academia, considering their significant presence and rapid growth in HEI. As the system expanded, and democratised it also became more feminised. Nevertheless, and despite efforts to minimise gender gaps, women are still underrepresented in top management and leading positions, contributing to increment the phenomenon of vertical segregation. Recently, within the NPM and managerialism context, HEI have been subjected to external pressures to create a new institutional and organisational environment aimed at substituting the collegial model with a managerial one. In this context, there is also a trend to replace the election by the nomination as the dominant process to occupy decision-making positions. In this paper, the authors discuss if and how the way decision-making bodies are constituted, influence the gender balance of their members. Both quantitative and qualitative data are analysed. Quantitative data result from the analysis of the gender constitution of the decision-making bodies of the university. Qualitative data focus on the content analysis of legal documents describing the mission of the decision-making bodies and in 12 interviews with institutional keyactors. The authors conclude that the gender balance decreases with the increasing importance of the decision-making body. Nevertheless, it is not possible to say that there is a direct relation between the way actors are chosen to these bodies and its gender balance. By other words, the way actors are chosen can not be seen as the only factor influencing the gender constitution of decision-making bodies. Furthermore, interviewees do not perceive the way actors are chosen as a relevant mechanism to improve gender equality and neither actions in this domain were identified to be included in Gender Equality Plans. This study provides a relevant contribution to the literature on mechanisms and strategies to improve gender equality in institutional decisionmaking processes and bodies.
Symmetric Searchable Encryption Supporting Rich Functionality and Enhanced Security

In this dissertation, we addressed three problems of SSE. First, we gave an SSE scheme which supports the multi-reader setting. Second, we proposed a generic solution for multi-keyword ranked search over the encrypted cloud data. Lastly, we proposed two forward/backward secure dynamic SSE which support geometric range search. Moreover, we introduced a security notion called content privacy which captures the leakages that are critical in the context of geometric range search but not considered by forward/backward security.
Disruption of NAP1 genes supresses the fas1 mutant phenotype and enhances genome stability

Histone chaperones mediate assembly and disassembly of nucleosomes and participate in essentially all DNA-dependent cellular processes. In Arabidopsis thaliana, loss-of-functions of FAS1 or FAS2 subunits of the H3-H4 histone chaperone complex CHROMATIN ASSEMBLY FACTOR 1(CAF-1) has a dramatic effect on plant morphology, growth and overall fitness. Altered chromatin compaction, systematic loss of repetitive elements or increased DNA damage clearly demonstrate the severity of CAF-1 dysfunction. How histone chaperone molecular networks change without a functional CAF-1 remains elusive. Here we present an intriguing observation that disruption of the H2A-H2B histone chaperone NUCLEOSOME ASSEMBLY PROTEIN 1 (NAP1) supresses FAS1 loss-of function. The quadruple mutant fas1nap1;1-3 shows wild-type growth and decreased sensitivity to genotoxic stress. Chromatin of fas1nap1;1-3 plants is less accessible to micrococcal nuclease and progressive loss of telomeres and 45S rDNA is supressed. Interestingly, the strong genetic interaction between FAS1 and NAP1 does not occur via direct protein-protein interaction. We propose that NAP1;1-3 play an essential role in nucleosome assembly in fas1, thus their disruption abolishes fas1 defects. Our data altogether reveal a novel function of NAP1 proteins, unmasked by CAF-1 dysfunction. It emphasizes the importance of a balanced composition of chromatin and shed light on the histone chaperone molecular network.
UJI EMPIRIS HUBUNGAN ANTARA TATA KELOLA PERUSAHAAN DAN PENGUNGKAPAN RISIKO

The purpose of this study is to test the relationship between corporate governance and corporate risk disclosure. The corporate governance in this study was proscribed with the frequency of audit committee meetings, the existence of risk monitoring committees, and the quality of external auditors. The population in this study is all non-financial company listed on the Indonesia stock Exchange in 2017. Purposive sampling used in this study with a total sample of 352 nonfinancial companies that comply predetermined criterias. The data analysis method used is a double linear regression analysis. The corporate governance variable in the study model is only able to describe 11.30% of risk disclosure variables. The empirical results in this study show that all corporate governance variables include the frequency of audit committee meetings, the existence of risk monitoring committees, and the quality of external auditors are significantly related to corporate risk disclosure.
Debris-bed friction during glacier sliding with ice–bed separation

Abstract Theory and experiments indicate that ice–bed separation during glacier slip over 2-D hard beds causes basal shear stress to reach a maximum at a particular slip velocity and decrease at higher velocities. We use the sliding theory of Lliboutry (1968) to explore how friction between debris particles in sliding ice and a rock bed affects this relationship between shear stress and slip velocity. Particle–bed contact forces and associated debris friction increase with increasing slip velocity, owing to increased rates of ice convergence with up-glacier facing surfaces. However, debris friction on diminished areas of the bed counteracts this effect as cavities grow. Thus, friction from debris alone increases only slightly with slip velocity, and for sediment particles larger than ~60 mm in diameter, debris friction peaks and decreases with increasing slip velocity. The effect on the sliding relationship is to steepen its rising limb and shift its shear stress peak to a slightly higher velocity. These results, which exclude the effect of debris friction on cavity size and debris concentrations above ~15%, indicate that the effect of debris in ice is to increase basal shear stress but not significantly change the form of the sliding relationship.
Impact of Intensity Standards on Alternative Fuel Adoption: Renewable Natural Gas and California’s Low Carbon Fuel Standard

Natural gas is a rapidly growing transportation fuel. While fossil natural gas is only slightly cleaner than conventional fuels, it provides a vector to introduce renewable natural gas (RNG) which can yield substantial emissions reductions. This paper considers RNG supply estimates from four possible sources: dairy manure, municipal solid waste, wastewater treatment plants, and landfill gas along with other major transportation fuels to evaluate the impact of California’s Low Carbon Fuel Standard (LCFS) a first of its kind fuel intensity standard. A static, multi-market, partial equilibrium, numerical model of the California fuel markets assesses the economic surplus and climate impact responses to the LCFS policy and compares the efficiency of the LCFS to a hypothetical carbon tax. Results indicate LCFS policy is sufficient to incentivize substantial quantities of RNG production. The LCFS approaches the efficiency of a carbon tax as the LCFS policy becomes more stringent when combined with a price ceiling.
MANAGEMENT SUPPORT PRACTICES TO PROMOTE TEACHERS’ INSTRUCTIONAL IMPROVEMENT FOR SUSTAINABLE DEVELOPMENT IN SECONDARY EDUCATION

This study ascertained the principals’ management support practices to promote teachers’ instructional improvement forsustainable development in secondary education in Anambra State. Two specific purposes were formulated and two research questions guided the study. The study adopted a descriptive survey design. The study was conducted in the six education zones in Anambra Statenamely:Aguata,Awka,Nnewi,Ogidi,Onitsha and Otuocha.The study population comprised 257 principals in public secondary schools in the six education of the State. No sampling was used due to the manageable size of the population. The instrument used for data collection is a structured 15 items researchers’ developed instrument titled; Principals’ Management Support Practices to Promote Teachers’ Instructional Improvement Questionnaire (PMSPTIIQ). The face validation of the instrument was established by three research experts. The Cronbach alpha was used to determine the reliability of the instrument. Coefficient value of 0.84 was obtained. Data were analyzed using mean and standard deviation. The findings of the study revealed among others that secondary school principals in Anambra State do not engage in instructional supervision practices of observing classroom instruction to ensure cur iculum coverage, monitoring teachers’ compliance to school schedules, meeting regularly with teachers to discuss instructional challenges and providing feedback to teachers after class observation. The study also found out that secondary school principals’ do not engage in adequate motivational practices to promote teachers’ instructional improvement for sustainable development in secondary education in Anambra State. Based on the findings, it was recommended that school administrators’ should always engage in instructional supervision practices by observing classroom instruction to ensure cur iculum coverage, monitoring teachers’ compliance to school schedules, meeting regularly with teachers to discuss instructional challenges and providing feedback to teachers after class observation among others. Conclusion wasdrawn.
Conically refracted Gaussian beam transformed by a lens

ABSTRACT The free-space evolution of a conically refracted Gaussian beam after being imaged by a lens is studied both theoretically and experimentally. It is shown that, in contrast to the longitudinal symmetry of a regular conically refracted beam with respect to its focal plane, the imaged beam acquires a strong longitudinal asymmetry, similarly to other known coherent beams with complex internal structure evolving upon propagation. Paraxial amplitude expressions for the two conical refraction components of the imaged beam are derived as functions of the imaging lens focal length and of the magnification value. A very good agreement between theoretical and experimental results is demonstrated.
An Independent Outcome Evaluation of an AIDS/HIV Prevention Program in Kenyan Schools

Background: The pervasive spread of HIV/AIDS in Africa necessitates development of social and behavioral interventions to impact sexual behaviors. The primary research objective was to determine if the Stay Alive program was effective in reducing sexual activity amongst the participants. The studyâ€™s secondary objective was to determine if students successfully learned target concepts taught by the Stay Alive program. Â Methods: Pregnancy rates were compared among 14,916 students from 52 Kenyan schools using a randomized, wait-list controlled, pre-post experimental design. Additionally, 957 children were randomly selected for more in-depth, mixed-methods, pre-post testing and interviewing to determine if students successfully learned Stay Alive program concepts. Data was collected during a year-long study that began in Fall of 2014. Â Results: The program was effective in reducing sexual activity as evidenced by a 67% reduction in pregnancy rates. The odds of a girl becoming pregnant after being taught the Stay Alive program was approximately one-third the odds of a girl becoming pregnant while on the waiting list (OR = 0.3549; 95%CI = 0.2712, 0.4644). After participating in the Stay Alive program, there was a 90% drop in the odds that a child believed he or she would die of HIV/AIDS, even though the level of belief that one would contract the disease did not change significantly. There was no significant shift in male students beliefs regarding the right of women to refuse male sexual advances (p = 0.066). Female students, on the other hand, significantly increased in their belief that their responses to advances would impact the future happiness of their families (OR = 2.08, p <0.001) and that, as a result, they had the right or need to reject those advances in order to protect their families (OR = 2.25, p <0.001). Â Conclusions: Social and behavioral interventions can play an important role in battling HIV/AIDS in Africa.
Racial/ethnic health disparities in chronic disease interventions and services across the socio-ecological model

Racial/ethnic health disparities in chronic disease int rventions and services across the socioecological model Roxana Virginia Chen Chair of the Supervisory Committee Allen Cheadle, PhD Affiliate Professor, Department of Health Services Director, Center for Community Health and Evaluatio n Group Health Research Institute Many chronic disease interventions have focused on individual-level services, such as one-on-one behavioral counseling, education or self -management classes, or direct clinical care. However, a growing body of research indicates that social factors play critical roles in shaping health and are “root causes” of health disparities. The socio-ecological model (SEM) suggests that factors across the socio-ecological spectrum, from individual genetics and behavior to environmental conditions and policies across one’s lif pan, all contribute to individual health. The three studies presented in this dissertation ex amine the role or impact of chronic disease interventions across the socio-ecological model and r cial/ethnic disparities in relation to each intervention. Study 1 monitors trends in individual -level diabetes services and care from 2001 to 2010 using national survey data, to examine if and to what extent individuals diagnosed with diabetes receive appropriate standards of clinical diabetes care or self-manage their condition
Neonatal morbidity and mortality in a Rural Tertiary Hospital in Nigeria

Background: Nigeria is one of the greatest contributors to the neonatal morbidity and maternity worldwide. Objective: This study was undertaken to determine the morbidity and mortality pattern of the neonatal admission including the outcome. Materials and Methods: This was a 1-year (March 2015 to February 2016) retrospective study of all the consecutive neonatal admissions in the special care baby unit (SCBU) of Federal Medical Centre Birnin Kudu, Jigawa State, Nigeria. The data obtained were entered into a predesigned pro forma and analyzed appropriately. Results: A total of 205 neonates were admitted to SCBU during the study period with the ratio of the males to females admitted was 2.1:1. The major causes of morbidity were neonatal sepsis (32.2%), birth asphyxia (29.3%), and prematurity (18.5%). In this study, overall mortality rate was 7.16% with birth asphyxia accounting for 13 (40.6%) of the total deaths (χ2 = 1.50, P = 0.68). One hundred and fifty-nine (77%) were discharged, 12 (6%) were discharged against medical advice, while 2 (1%) were referred. Conclusion: Neonatal sepsis, birth asphyxia, and prematurity are the major causes of neonatal morbidity and mortality in this locality.
Overview of physical therapy graduation courses in Brazil: current scenario

Introduction: After the regulation of Physical Therapy (PT) in 1969, there were only six undergraduate courses in Brazil. In the 90s, higher education underwent major expansion in all professions and the same occurred to PT, with consequent increase in the number of professionals in the labor market and privatization of education. Objective: To describe the current situation of PT courses in Brazil offered by Higher Education Institutions (IES). Methods: The data for the region, academic organization, situation, period, school system, administrative category, vacancies, course hours and duration were obtained from the website of the Ministry of Education (MEC) and refer to the year of 2013. The descriptive analyzes of central tendency, dispersion and percentage were performed in Stata 9®. Results: From the total of 550 IES registered in the MEC, 281 (51%) were in the Southeast. Regarding the academic organization, 341 (62%) corresponded to universities and 483 (87.9%) of the IES were private. Of the courses, 521 (94.7%) are active, the predominant school system was the semiannual (91.5%) and 438 were part-time. The average vacancies authorized by the IES were 129 ± 102, with at least 44,900 vacancies available in the country. Of the courses, 75% had 4,000 hours of duration with the minimum of seven semesters and a maximum of fourteen. Conclusion: The data show a higher offer of PT courses in the private sector compared to the public. There was a progressive concentration of courses and vacancies in the Southeast, especially in Sao Paulo.
Audio subtitling: dubbing and voice-over effects and their impact on user experience

ABSTRACT This article reports the outcome of an experiment in which 42 Spanish blind and partially sighted participants were exposed to two diverging audio subtitling strategies: audio subtitles with a voice-over effect and audio subtitles with a dubbing effect. Data on the users’ emotional responses were collected through a tactile and simplified version of the SAM questionnaire and psychophysiological recordings of electrodermal activity and heart rate. The results obtained from both methods do not show statistically significant differences between the two effects. However, results from the questionnaire proved that emotions were induced in the participants calling for more research on the topic and with the application of such methods.
