TALENT MANAGEMENT AND COMPETITIVE ADVANTAGE: THE MODERATION ROLE OF WORKPLACE CULTURE

The study aims to analyse the effect of talent management on competitive advantage through workplace culture moderation. The data was collected from 425 full-time employees from the top ten deposit money banks in Lagos State using a questionnaire as a data collection tool. This research uses a quantitative approach with a survey method. Respondents were selected from the top ten deposit money banks in Lagos State through a stratified random sampling technique. The collected data were analysed using hierarchical regression analysis (HRA) to test the hypothesis and evaluate the regression model specified. These findings show that the effect of talent management on competitive advantage was significantly moderated by workplace culture (β = -0.015, R2 ∆ = 0.003, F∆ = 13.865, p<0.05). It was concluded that workplace culture moderated the relationship between talent management and competitive advantage in the selected deposit money banks in Lagos State. A recommendation was anchored on management to create a positive workplace culture that supports talent management practises to achieve sustainable competitive advantage.  Article visualizations

Rainfall Variability and Trend Analysis over Lokoja, Nigeria

Studies on rainfall variability and trends are of great importance, particularly to the nations where rainfed agriculture is predominant. This study used CRU data (CRU_TS 4.01) to examine the temporal variability of rainfall data over Lokoja. Statistical tests were employed to examine variability and trend in monthly, seasonal and annual time series. Analysis of variability showed that the rainy seasons and annual rainfall had less variability (CV 30) in some months in the rainy season (April, July and August). Standardised precipitation index showed alternation of wet and dry period conditions had been witnessed in the study area. Trend analysis showed more positive trends had been experienced from 1970 through 2010. The variability in rainfall and the increasing trend may have a tremendous effect on water resources availabilities and vulnerabilities of Lokoja

Practice patterns for acute ischemic stroke workup: A longitudinal population‐based study

Background We examined practice patterns of inpatient testing to identify stroke etiologies and treatable risk factors for acute ischemic stroke recurrence. Methods and Results We identified stroke cases and related diagnostic testing from four 1‐year study periods (July 1993 to June 1994, 1999, 2005, and 2010) of the Greater Cincinnati/Northern Kentucky Stroke Study. Patients aged ≥18 years were included. We focused on evaluation of extracranial arteries for carotid stenosis and assessment of atrial fibrillation because randomized controlled trials supported treatment of these conditions for stroke prevention across all 4 study periods. In each study period, we also recorded stroke etiology, as determined by diagnostic testing and physician adjudication. An increasing proportion of stroke patients received assessment of both extracranial arteries and the heart over time (50%, 58%, 74%, and 78% in the 1993–1994, 1999, 2005, and 2010 periods, respectively; P &lt;0.0001 for trend), with the most dramatic individual increases in echocardiography (57%, 63%, 77%, and 83%, respectively). Concurrently, we observed a decrease in strokes of unknown etiology (47%, 48%, 41%, and 38%, respectively; P &lt;0.0001 for trend). We also found a significant increase in strokes of other known causes (32%, 25%, 45% and 59%, respectively; P &lt;0.0001 for trend). Conclusions Stroke workup for treatable causes of stroke are being used more frequently over time, and this is associated with a decrease in cryptogenic strokes. Future study of whether better determination of treatable stroke etiologies translates to a decrease in stroke recurrence at the population level will be essential. </jats:sec

Solidarity and Social Behaviour: how did this help communities to manage COVID-19 pandemic?

Purpose – During the coronavirus (COVID-19) pandemic lockdowns, stay at home or work from home, many have argued that the westernised non-pharmaceutical interventions (NPI) do not provide remedial in low-income countries like Nigeria, where informal job seekers, street traders, informal labourers and artisans depend mainly on the informal economy. By applying social solidarity (SS) and community-based approach (CBA), the authors evaluate individual acts (trust, altruism and reciprocity) during the lockdown and how these practices evolve from individual approaches to collective actions. Design/methodology/approach – This study reflects on pragmatism research paradigm that enables researchers to maintain both subjectivity in their reflections and objectivity in data collection and analysis. The authors adopt a qualitative method through purposeful and convenience sampling procedure. Data were analysed thematically to identify elements of SS, individual acts, collective or community actions and perceptions. Findings – The findings reveal that COVID-19 had a disproportionate impact (lack of food and a fall in daily income) on workers, informal job seekers, informal businesses operators and the poor households. As such, the study developed a reflective model of solidarity exhibited by individual acts and collective acts (practices of resource pooling, information sharing, women empowerment, distribution of palliatives and donations) within trusted circles that helped people cope with the lockdown experiences. Practical implications – Solidarity represents beliefs, practices of values and norms. The SS exhibited by people through NPI would have implications on planning and monitoring the effectiveness of public health programmes during a pandemic in the future. Social implications – The findings of citizens and community actions have implications related to the process of building communities – coming together – and solidarity that enhances social development with implications on community health policy agenda during disasters, emergencies and health pandemic. Originality/value – This is one of the first studies to analyse the relationship between trust, altruism, reciprocity, SS and CBA during the COVID-19 pandemic. Also, it seems reasonable to clarify the concept of SS given the lack of clarity about the definitions from previous studies

EVALUATION OF THE AGRONOMIC PERFORMANCE AND NUTRITIVE VALUES OF TEPHROSIA BRACTEOLATA GUILL. & PERR. AND GMELINA ARBOREA ROXB PRUNNINGS AT DIFFERENT STAGES OF GROWTH

This study was carried out to investigate the growth, dry matter yield and chemical composition of Tephrosia bracteolata and Gmelina arborea at Teaching and Research Farm, Federal University of Agriculture, Abeokuta, Nigeria. The objective of this study was to evaluate the effect of different stages of growth of T. bracteolata and G. arborea on their agronomic performance, herbage yield and nutritive value in the humid zone of Nigeria. Data were collected at 8, 12, 16 and 20 weeks after planting (WAP). Results showed that T. bracteolata attained the height of 161 cm at 20 WAP, though not significantly different from the height at 16 WAP. The leaf number (24), branch number (7) and dry matter yield of T. bracteolata were recorded highest at 16 WAP. The height of G. arborea was on constant increase throughout the experimental period. The crude protein (CP) and ether extract (EE) contents of the two browse plants were highest at 8 WAP and thereafter, declined throughout the experimental period. Fibre fractions, the neutral detergent fibre (NDF), acid detergent fibre (ADF) and acid detergent lignin (ADL) had a least value for both browse species at 8 WAP and highest values at 20 WAP. From the study, considering the dry matter yield and nutritive value, T. bracteolata being an annual species, can be harvested at 16 WAP when the quality and quantity will support livestock productivity and can be conserved to be fed to ruminant animals during dry season when feed availability and quality are extremely low. However, planting of G. arborea should be encouraged being a perennial browse plant that will support livestock productivity during the dry season in the tropics. In conclusion, T. bracteolata and G. arborea grow rapidly and are recommended as forage of high nutritive values that meet ruminant animal protein requirements especially during the dry season

Experimental analytical design of CNC machine tool SCFC based on electro-pneumatic system simulation

AbstractA Smart Clamping Force Control (SCFC) is adapted to hold sensitive workpiece using magnetic proximity switch during a machining operation on the CNC machine tool. It has been ascertained that work-holding of different workpiece materials and shapes during machining operation is one of the problems encountered during CNC milling machining operations. This work proposes a novel clamping strategy for workpieces with the aid of SCFC. The purpose of the study is to adjust the forward movement of the clamp and reduce the damage caused by the clamp on the workpiece, this depends on the material of the work-piece. The speed of the clamp is reduced using the inlet flow control throttle valve and a magnetic proximity switch (MPS). It provides careful handling of workpiece and prevent it from damage and as well optimizes the forward movement of the cylinder. The proposed strategy is based on dynamic machine loading in which the impact of applied forces were monitored to optimize the clamping control system of the machine tool. The mode of operation and performance of the SCFC were simulated in the FluidSIM® software, and the validated results was presented on Festo workstation. This work therefore further elucidate the fundamental design criterion for machine tool clamping forces and the sustainable manufacture of its components

Epidemiological profile of the Ebola virus disease outbreak in Nigeria, July-September 2014

Introduction: In July 2014, Nigeria experienced an outbreak of Ebola virus disease following the introduction of the disease by an ill Liberian Traveler. The Government of Nigeria with the support of Technical and Development Partners responded quickly and effectively to contain the outbreak. The epidemiological profile of the outbreak that majorly affected two States in the country in terms of person, place and time characteristics of the cases identified is hereby described. Methods: Using field  investigation technique, all confirmed and probable cases were identified, line-listed and analysed using Microsoft Excel 2007 by persons, time and place. Results: A total of 20 confirmed and probable cases; 16 in Lagos (including the index case from Liberia) and 4 in Port Harcourt were  identified. The mean age was 39.5 ± 12.4 years with over 40% within the age group 30-39 years. The most frequent exposure type was direct physical contact in 70% of all cases and 73% among health care workers. The total case-fatality was 40%; higher among healthcare workers (46%) compared with non-healthcare workers (22%). The epidemic curve initially shows a typical common source outbreak, followed by a propagated pattern. Conclusion: Investigation revealed the size and spread of the outbreak and provided information on the characteristics of persons, time and place. Enhanced surveillance measures, including contact tracing and follow-up proved very useful in early case detection and containment of the outbreak

Surveillance and Outbreak Response Management System (SORMAS) to support the control of the Ebola virus disease outbreak in West Africa

In the context of controlling the current outbreak of Ebola virus disease (EVD), the World Health Organization claimed that ‘critical determinant of epidemic size appears to be the speed of implementation of rigorous control measures’, i.e. immediate follow-up of contact persons during 21 days after exposure, isolation and treatment of cases, decontamination, and safe burials. We developed the Surveillance and Outbreak Response Management System (SORMAS) to improve efficiency and timeliness of these measures. We used the Design Thinking methodology to systematically analyse experiences from field workers and the Ebola Emergency Operations Centre (EOC) after successful control of the EVD outbreak in Nigeria. We developed a process model with seven personas representing the procedures of EVD outbreak control. The SORMAS system architecture combines latest In-Memory Database (IMDB) technology via SAP HANA (in-memory, relational database management system), enabling interactive data analyses, and established SAP cloud tools, such as SAP Afaria (a mobile device management software). The user interface consists of specific front-ends for smartphones and tablet devices, which are independent from physical configurations. SORMAS allows real-time, bidirectional information exchange between field workers and the EOC, ensures supervision of contact follow-up, automated status reports, and GPS tracking. SORMAS may become a platform for outbreak management and improved routine surveillance of any infectious disease. Furthermore, the SORMAS process model may serve as framework for EVD outbreak modelling

User evaluation indicates high quality of the Surveillance Outbreak Response Management and Analysis System (SORMAS) after field deployment in Nigeria in 2015 and 2018

During the West African Ebola virus disease outbreak in 2014-15, health agencies had severe challenges with case notification and contact tracing. To overcome these, we developed the Surveillance, Outbreak Response Management and Analysis System (SORMAS). The objective of this study was to measure perceived quality of SORMAS and its change over time. We ran a 4-week-pilot and 8-week-implementation of SORMAS among hospital informants in Kano state, Nigeria in 2015 and 2018 respectively. We carried out surveys after the pilot and implementation asking about usefulness and acceptability. We calculated the proportions of users per answer together with their 95% confidence intervals (CI) and compared whether the 2015 response distributions differed from those from 2018. Total of 31 and 74 hospital informants participated in the survey in 2015 and 2018, respectively. In 2018, 94% (CI: 89-100%) of users indicated that the tool was useful, 92% (CI: 86-98%) would recommend SORMAS to colleagues and 18% (CI: 10-28%) had login difficulties. In 2015, the proportions were 74% (CI: 59-90%), 90% (CI: 80-100%), and 87% (CI: 75-99%) respectively. Results indicate high usefulness and acceptability of SORMAS. We recommend mHealth tools to be evaluated to allow repeated measurements and comparisons between different versions and users

Age, Sex, and Racial Differences in Neuroimaging Use in Acute Stroke: A Population-Based Study

BACKGROUND AND PURPOSE: Limited information is available regarding differences in neuroimaging use for acute stroke work-up. Our objective was to assess whether race, sex, or age differences exist in neuroimaging use and whether these differences depend on the care center type in a population-based study. MATERIALS AND METHODS: Patients with stroke (ischemic and hemorrhagic) and transient ischemic attack were identified in a metropolitan, biracial population using the Greater Cincinnati/Northern Kentucky Stroke Study in 2005 and 2010. Multivariable regression was used to determine the odds of advanced imaging use (CT angiography/MR imaging/MR angiography) for race, sex, and age. RESULTS: In 2005 and 2010, there were 3471 and 3431 stroke/TIA events, respectively. If one adjusted for covariates, the odds of advanced imaging were higher for younger (55 years or younger) compared with older patients, blacks compared with whites, and patients presenting to an academic center and those seen by a stroke team or neurologist. The observed association between race and advanced imaging depended on age; in the older age group, blacks had higher odds of advanced imaging compared with whites (odds ratio, 1.34; 95% CI, 1.12–1.61; P < .01), and in the younger group, the association between race and advanced imaging was not statistically significant. Age by race interaction persisted in the academic center subgroup (P < .01), but not in the nonacademic center subgroup (P = .58). No significant association was found between sex and advanced imaging. CONCLUSIONS: Within a large, biracial stroke/TIA population, there is variation in the use of advanced neuroimaging by age and race, depending on the care center type
