Attitude of Civil Servants Towards the Use of Research Information in Policymaking in Selected Ministries in Lagos State, Nigeria
Information is very essential in any organization especially in a government based environment where information are needed for policy making. However, some of the instruments used for getting information are not well managed by the civil servants who are the custodian of this research information. This study investigated the attitude of policymakers in terms of the types, availability and accessibility of research information in making policy. Focusing particularly on the types of research information needed by senior civil servants in making policies, frequency of use of research information source, accessibility of information for decision making and the challenges encountered in the course of using them. The descriptive research method was adopted, using a pre-tested self-administered questionnaire to gather information from 166 senior civil servants randomly selected from selected ministries in Lagos state, as data collection instrument. Results indicated that information provided by ones ministry, information on project implemented by ones ministry , information on infrastructural development and information on human resources and skills available at ones ministry are the most used information by policymakers in making policy. The study also showed that internal files, colleagues or superior, newspaper, government publication and internet are the most frequently used and accessible information sources for policymaking. Impracticability of research recommendation politically and financially, too much information to absorb and contradictions in information from different researchers are the major constraints to research output. The study recommended among other suggestions that policymakers must consider wider ranges of research information sources for effective policy making
Awareness of Selected Information and Communication Technologies for Extension Training on Improved Agricultural Practices Among Extension Agents of Ogun and Oyo States, Nigeria
Over several decades agricultural production in Nigeria has improved through the extension services, coupled with the invention of ICTs in recent time. The application of any ICT gadget would be determined by its awareness and its appropriateness for the intended purpose desired to serve by the user. This study, therefore, assesses awareness of selected ICTs for disseminating agricultural information to farmers by the Extension Agents (EAs) of Ogun and Oyo States, Nigeria. Multistage sampling method was employed to obtain data from 287 EAs with interview schedule and Focus Group Discussion (FGD). Using both descriptive and inferential statistical tools, the paper analyses personal characteristics of the EAs in both States; agricultural crop information disseminated through the selected ICTs and level of awareness of the selected ICTs among the EAs. It was deduced in the study that the EAs and extension agency used different ICTs in disseminating agricultural information to farmers in the areas, though the EAs have different level of awareness on the usage of selected ICTs for such purpose, with GSM-phones ranked 1st (wms=4.76), radio (wms=4.63=2nd), extension bulletins/posters/newsmagazine ranked 3rd (wms=3.74) respectively. The PPMC analysis revealed that age (0.117*), educational level (0.145*) and years of working experience (0.176**) of EAs recorded a significant relationship with awareness level of selected ICTs at both 1% and 5%. The T-test analysis further revealed that a significant difference existed in the awareness level of the selected ICTs among the EAs of Ogun and Oyo States. The study, therefore, recommends the need to encourage the use of other ICT gadgets apart from GSM-phonesthrough adequate awareness on the use and appropriateness of ICTs for disseminating agricultural information to users and also socioeconomic characteristics of the applicants for extension service should be given consideration during recruitment exercise.

OPTICAL DISPERSION COMPENSATION USING DIFFERENT MODULATION FORMATS
Optical dispersion is the main impediment to optimal utilization of optical fiber backbone ability to satisfy the capacity need of today’s emerging telecommunication networks. In this paper, the investigation of post - and symmetrical dispersion compensation fibers (DCF) have been examined in a 16 and 32 channel 40Gbps dense wavelength division multiplexing (DWDM) system using different modulation formats. Simulation results obtained show a significant improvement in the quality factor and bit error rate when DCF is used. The performance of the methods however shows dependency on the number of channels in the system, the modulation, and the channel condition
Development and Validation of the Mental Health Professionals\u27 Attitude Towards People Living with HIV/AIDS Scale (MHP-PLHIV-AS)
This study focused on the creation and validation of an instrument to measure mental health professionals\u27 attitudes towards people living with HIV/AIDS. Rasch analyses (Rash, 1960, 1980) provided evidence to support a two-dimensional (societal and personal dimensions) measurement of this attitude construct
Methyl orange, an organic dye: its health impact and sorptive removal from waste water
AbstractMethyl Orange (MO) a member of Azo dyes are commonly used as synthetic dyes in textile, food, paper and cosmetics. Their use is easy and cost-effective, compared with natural dyes. However, azo bonds are hardly removed because of their high water solubility as well as low exhaustion with the potential for persistence and accumulation in the environment, therefore aqueous solution of MO is toxic and irritating. Thus, the removal of them from industrial wastewaters is capital with regard to protect public health, environment, and aquatic life
Martensite-to-austenite reversion and recrystallization in cryogenically-rolled type 321 metastable austenitic steel
The annealing behavior of cryogenically-rolled type 321 metastable austenitic steel was established. Cryogenic deformation gave rise to martensitic transformation which developed preferentially within deformation bands. Subsequent annealing in the range of 600 C to 700 C resulted in reversion of the strain-induced martensite to austenite. At 800 C, the reversion was followed by static recrystallization. At relatively-low temperatures, the reversion was characterized by a very strong variant selection, which led to the restoration of the crystallographic orientation of the coarse parent austenite grains. An increase in the annealing temperature relaxed the variant-selection tendency and provided subsequent recrystallization thus leading to significant grain refinement. Nevertheless, a significant portion of the original coarse grains was found to be untransformed and therefore the fine-grain structure was fairly heterogeneous
EBSD characterization of cryogenically rolled type 321 austenitic stainless steel
Electron backscatter diffraction was applied to investigate microstructure evolution during cryogenic rolling of type 321 metastable austenitic stainless steel. As expected, rolling promoted deformation-induced martensitic transformation which developed preferentially in deformation bands. Because a large fraction of the imposed strain was accommodated by deformation banding, grain refinement in the parent austenite phase was minimal. The martensitic transformation was found to follow a general orientation relationship, {111}γ||{0001}ε||{110}α′ and 〈110〉γ||〈11-20〉ε||〈111〉α′, and was characterized by noticeable variant selection
Extending our scientific reach in arboreal ecosystems for research and management
The arboreal ecosystem is vitally important to global and local biogeochemical processes, the maintenance of biodiversity in natural systems, and human health in urban environments. The ability to collect samples, observations, and data to conduct meaningful scientific research is similarly vital. The primary methods and modes of access remain limited and difficult. In an online survey, canopy researchers (n = 219) reported a range of challenges in obtaining adequate samples, including ∼10% who found it impossible to procure what they needed. Currently, these samples are collected using a combination of four primary methods: (1) sampling from the ground; (2) tree climbing; (3) constructing fixed infrastructure; and (4) using mobile aerial platforms, primarily rotorcraft drones. An important distinction between instantaneous and continuous sampling was identified, allowing more targeted engineering and development strategies. The combination of methods for sampling the arboreal ecosystem provides a range of possibilities and opportunities, particularly in the context of the rapid development of robotics and other engineering advances. In this study, we aim to identify the strategies that would provide the benefits to a broad range of scientists, arborists, and professional climbers and facilitate basic discovery and applied management. Priorities for advancing these efforts are (1) to expand participation, both geographically and professionally; (2) to define 2–3 common needs across the community; (3) to form and motivate focal teams of biologists, tree professionals, and engineers in the development of solutions to these needs; and (4) to establish multidisciplinary communication platforms to share information about innovations and opportunities for studying arboreal ecosystems
Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
Does Financial Inclusion Moderate CO2 Emissions in Sub-Saharan Africa? Evidence From Panel Data Analysis
The threat posed by climate change has become a reality in the public sphere. This research looks at how financial inclusion affects carbon dioxide emissions in Sub-Saharan Africa (SSA) countries from 2004 to 2017. The panel autoregressive distributed lag and panel granger causality approaches are used to determine if financial inclusion reduces CO2 emissions in Sub-Saharan African countries. The PARDL results demonstrated that, over time, financial inclusion, GDP per capita, industrialization, and trade openness have a substantial beneficial influence on carbon emissions in SSA countries. The result suggests that these considered variables contribute significantly to CO2 emissions while urbanization and energy intensity reduce CO2 emissions in SSA. Financial inclusion and other control variables have no significant impacts on carbon emission in SSA in the short run. The findings of the granger causality test further confirm the direction of causality, revealing that financial inclusion, GDP per capita, industrialization, energy intensity, and trade openness, granger cause carbon emission in SSA countries. Meanwhile, carbon emission does not granger cause any of the considered factors. The study concludes that financial inclusion increases carbon emission in SSA countries, given the poor state of financial inclusion. Our findings advocate for a policy framework that would focus efforts on connecting financial inclusion measures with environmental legislation across SSA nations
