The Empiricist Criteria of Meaning And The Problem of Translation

Generally speaking, the branches of philosophy have traditionally been listed to include Ethics, logic, metaphysics, epistemology and aesthetics. However, it has over the years embraced studies in socio political philosophy, philosophy of law, philosophy of mind, philosophy of language and so on. The study of language in philosophy is not in the same way as those who specialize in linguistics. However, its study creates proper understanding and removes forms of ambiguity that may be found in language in particular and communication in general. Philosophers of language have discussed many issues which includes ‘meaning’, ‘sense’, ‘reference’ and many others. In this paper we shall attempt a critical analysis of the Logical Empiricist’s criteria of ‘meaning’. The paper begins with the analysis of the concept of ‘meaning’ and why philosophers of language are so particular about ‘meaning’ either of words, sentences or expression. The paper also examines logical empiricist criteria of meaning and its relevance to communication and translation of words or statements. The paper argues that the empiricist criteria of meaning entails some absurdities and poses serious problem to communication and translation in human society. Thus, it should not be accepted in absolute term. Keywords: Logical empiricism, Language, Meaningfulness, Communication and Society

Thin layer drying models for sweet potato in tray dryer

Sweet potato is increasingly becoming important and popular as food stuff all over the world.  Therefore investigation of thin layer drying of sweet potato slices in three different dimensions was carried out between 50oC and 80oC in tray dryer using hot air at a flow rate of 2.5 m/s and 10% relative humidity.  Eight thin-layer drying kinetic models were assessed on blanched and unblanched sweet potato slices presented in three different dimensions.  The drying rate was observed to decrease with thickness and mass at a constant drying temperature.  Also, the drying rate was found to increase with temperature and the blanched slices dried faster than unblanched slices.  The eight models investigated fitted the experimental data of the six sweet potato samples between 50oC and 80oC adequately.  However, Page model was found to be the best for all the samples.  The results obtained are comparable to some of the reported works. Keywords: sweet potato, thin-layer drying models, page model, tray dryer, diffusion mechanis

Framework for overcoming barriers of complementary and alternative medicine acceptance into conventional healthcare system

Health disparities have been widely recognized as a problem throughout the world. This paper provided a strengthened collaborative virtual framework for overcoming barriers towards accepting complementary and alternative medical practice into conventional healthcare system. Quantitative and qualitative data were gathered with semi-structured questionnaires and interviews from General Practitioners (GPs) with Complementary and Alternative Medicine (CAM) knowledge, CAM Practitioners with biomedicine knowledge, CAM patients, and scholars. 2,760 semi-structured questionnaires exploring knowledge, attitudes, and skills’ barriers to integrative medical collaboration efforts were administered. Focus group discussions were held interviewing GPs, CAM practitioners, and others claiming effective prescriptions. Practitioners’ team meetings, retreats, interaction, and prescription operations were observed. In this study, a videoconferencing-based healthcare services delivery system was developed and implemented for seamless exchange of healthcare information. 2,591 (93.5%) questionnaires representing 657 physicians (23.80%), 997 CAM practitioners (36.12%), 855 patients (30.98%), and 82 healthcare researchers (2.97%) responded, while 169 (6.12%) declined response. Fifty-two percent of the 657 GPs still referred patients for CAM treatments. Patients found complementary approaches more aligned with “their own values, beliefs, and philosophical orientations”. Non-medical acceptance of CAM (43.27%) continued impeding CAM growth in Nigeria. CAM practitioners require evidence-based knowledge towards finding solutions and suggestions for seamlessly integrating CAM with modern healthcare practices. Key words: Collaboration, complementary and alternative medicine, integrated delivery system, videoconferencing

Vocational Skill Acquisition and Venture Creation among Undergraduates in Osun State

The study assessed the intention of venture creation from vocational skill acquisition training among undergraduate students in Osun state. Specifically, the study identified skills acquired by respondents during vocational training, evaluated respondents’ intention to start new venture(s), and assessed the factors affecting venture creation. The population for this study comprised of undergraduate students that have learnt or learning at least one vocational skill. 336 respondents were selected using non-probability purposive sampling technique. Data collected was analysed using descriptive and inferential statistics. The findings from the study showed that fashion designing (30.7%), vocational computer skills (16.1%), and photography (14.9%) were the most acquired technical skills while time management (66.4%), business management (64.3%) and financial management (63.4%) were the most acquired non-technical skills during vocational trainings. Majority (72.2%) had moderate level of intention of venture creation. Internal and external factors greatly affect venture creation with grand mean of 3.34 ± 0.66 and 3.35 ± 0.70 respectively. The correlation coefficient of the independent variable reveals that acquisition of vocational skill (r= 0.052, P= 0.339) had no significant relationship with intention of venture creation. The study concluded that learning or acquiring a particular vocational skill does not translate directly to venture creation. The study therefore recommends that while entrepreneurship and skill acquisition is being encouraged among students, government in partnership with other institutions should provide incentives to stimulate venture creation from acquired skills

Monitoring drought and effects on vegetation in Sokoto state, Nigeria using statistical and geospatial techniques

This paper aimed at assessing drought occurrences and its effects on vegetation cover in Sokoto State, Nigeria using geospatial and statistical techniques. Monthly precipitation data which span through a period of 40 years (1980-2010) and 30 years (1982-2011) respectively were used for generating Standardized Precipitation Index (SPI) graphs and maps. LandSat   imageries of bands 3 and 4 acquired by Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM+) Sensor were used for generating Normalized Difference Vegetation Index (NDVI). SPI and NDVI were generated for the study area based on inter-annual and decadal timescale. Findings showed that SPI values varied from extremely dry condition to extreme wet condition although near normal condition ranked highest while extremely wet condition ranked least.  It also revealed that most of the Local Government Areas experienced near normal conditions but  Isa, Sabon Birni and little part of the boundary between Goronyo and Wurno experienced moderately wet conditions between 1982 and 1991. It was further observed that the whole region was dominated with near normal condition except Sabon Birni and Isa LGAs that experienced extremely, severely and moderately wet condition between 1992 and 2001. In contrast, the SPI values for over 90% of the state  between 2002 and 2011 fall within the severely dry conditions. Findings further showed that change scenarios observed from the derived NDVI and SPI maps indicated that the climatic variability currently being experienced is likely to increase and intensify in future. It is obvious that urgent attention on drought management over this region is needed.Keywords: Drought, SPI, NDVI, Vegetation Cover, Landsat Imageries, Northern Nigeri

EFFECTS OF COMPENSATION PRACTICES ON ACADEMIC STAFF’S JOB PERFORMANCE IN FEDERAL UNIVERSITY OF AGRICULTURE, ABEOKUTA, OGUN STATE, NIGERIA

The study examined the effect of compensation practices on academic staff’s job performance in Federal University of Agriculture, Abeokuta, Ogun State, Nigeria. Multi stage sampling technique was used to purposively select 3 Agricultural base colleges followed by proportionate stratified sampling technique where respondents were randomly selected. One hundred and three (103) respondents from the three colleges of agriculture of the university were selected of which 92 questionnaires were retrieved. Data obtained was analyzed using descriptive and inferential statistics such as mean, standard deviation, chi-square and Pearson Product Moment Correlation. Finding revealed that the mean age of the respondents was 42.71 years, 71.7% of the respondents were male, 81.5% of them were married and 79.3% of the respondents were PhD holders. The mean years of experience was 10 years while their mean income was ₦217447.29. Most (79.4%) academic staff perceived that there is a pressing need to review and rationalize the pay structure to improve employee efficiency, some of the compensation packages available were; retirement benefit (100%), study leave (91.3%), career development opportunity (82.6%). The major constraints to compensation strategies identified were poor insurance scheme (21.7%), inadequate welfare package (20.7%) and poor communication network (19.6%). Furthermore, a significant relationship existed between respondents’ age (r= -0.204, P<0.05), compensation packages (r= 0.26, P<0.05) and their job performance. The results concluded that academic staff perceived a pressing need to review the compensation packages by involving them in the compensation decision making process. Effective management and implementation of compensation packages is highly recommended. , , Job Performanc

Prevalence of Malaria and Predisposing Factors to Antimalarial Drug Resistance in Southwestern Nigeria

High transmission rate and drug resistance have been implicated in the spread and re-emergence of malaria in areas where the disease had been eradicated. The objective of this study was to determine the prevalence of falciparum malaria and pre-disposing factors to malaria among patients presenting with fever in selected State Hospitals in Ogun State, Southwestern Nigeria. Four thousand and sixty six patients were recruited into this study. Scientific and Ethical clearance was obtained for this study. Blood samples were collected for malaria screening from the subjects. Structured questionnaires were administered to patients and parents of infants to determine the factors that could lead to the development of drug resistance by the parasite in the study population. Out of 4066 subjects screened during the study period, 61.1% were positive for falciparum malaria. Highest prevalence of 70.8% was recorded in children 1-5 years, also the group with highest parasitemia (1080). The study showed that 24.6% of the patient visited hospitals for treatment, 12% use local healers while 25.0% bought antimalarial drugs without prescription. Moreover, some subjects use more than one method in their management of malaria. Those who combined antimalarial drugs with traditional medicine from local healers were 17.4%. Only 18% of the sample population used insecticide treated mosquito nets, 42.3% used window and door nets, while 13% did not employ any mosquito preventive method. Uncontrolled use of drugs and exposure of parasites to the drugs should be monitored in areas where the parasite is still sensitive to the drug

Delayed referral and treatment of paediatric cancer in Nigeria: Time to stop blaming the victim

Background: Caregiver delay in presentation has been cited as a major contributor to poor prognosis of paediatric cancers in low-middle income countries like Nigeria. This study explored the time duration between onset of symptoms and presentation to healthcare facilities, diagnosis, and referral for specialist care. Methods: Data were compiled from caregivers of newly registered children at a teaching hospital in Nigeria. Sociodemographic and clinical history of the child were taken. Type of cancer, date of diagnosis, centre where the diagnosis was made, treatment start date, and duration of symptoms until treatment were elicited from consenting caregivers and documented. Results: Acute lymphoblastic leukaemia was the most prevalent cancer type among the patients. The mean time from first symptom to presentation was 15 weeks and from presentation at any health care facility to specialist referral and diagnosis was 38 and 39 weeks, respectively. Time from diagnosis to treatment was a mean of 8 weeks (range: 1 to 27 weeks) Conclusion: Delayed presentation has become a commonly cited factor for poor cancer outcomes in Nigeria and may often inaccurately assign blame to the patient/caregivers. The results of this study point to delayed detection, delayed diagnosis and delayed referral for specialist care, as more accurate contributors to late-stage presentation and consequently worse outcomes of paediatric cancers in Nigeria. Strengthening of community and primary level healthcare professionals’ understanding of paediatric cancers, establishment of simple detection algorithms and national implementation of efficient referral protocols will potentially reduce delays in specialist attention and improve outcomes

Chest X-ray findings in HIV- infected Highly Active Antiretroviral Treatment (HAART) - naïve patients

Introduction: Patients with human immunodeficiency virus (HIV) infection frequently present with a wide spectrum of pulmonary and cardiaccomplications from the virus, opportunistic infections and neoplasms that may be associated with a high mortality rate. Diseases of the respiratorytract account for about half of deaths from AIDS, while cardiac diseases account for more than a quarter of deaths from AIDS. This study aimed atdetermining the prevalence of pulmonary and cardiac diseases using a chest radiograph in HAART-naïve HIV-infected patients. Methods: Thisstudy was conducted at Lagos State University Teaching Hospital (LASUTH) HIV clinic between September 2010 and August 2011 amongst allregistered HAART-naïve HIV/AIDS patients. Patients had posterior-anterior chest radiographs done in full inspiration. Participants were asked andaided to fill the structured questionnaires to obtain demographic data. Results: Out of a total of one hundred and two recruited for the study, 54 (52.94%) had a normal chest radiograph, while 48 (47.06%) had abnormal chest radiograph .The abnormal findings included, 27.45% who hadbronchopneumonia, 6.86% cardiomegaly, 5.88% pulmonary tuberculosis, 5.88% radiological features of congestive cardiac failure, and 0.98%bronchitis. Conclusion: It appears that more than half of HAART–naïve HIV-infected patients have normal chest radiographs. Bronchopneumonia(27.5%) is the commonest pulmonary abnormality associated with HIV infection, while the prevalence of pulmonary tuberculosis is 5.88%.Key words: Chest X-ray, HIV-infected, HAART-naïve

PREVALENCE AND MANAGEMENT OF FALCIPARIUM MALARIA AMONG INFANTS AND CHILDREN IN OTA, OGUN STATE, SOUTHWESTERN NIGERIA

Studies were carried out to determine the prevalence of malaria parasite infection among infants and children (0-12yrs) in Ota, Southwestern Nigeria between April and December 2008. The two hospitals used were Ota General Hospital and Covenant University Health Centre, Canaanland, Ota. Thick and thin films were made and stained using standard parasitological procedures. Structured Questionnaires were distributed to ascertain the age, sex, drugs or insecticides used and state of health of the subjects before recruiting them into the study. Overall, 215 (80.5%) of the 267 children investigated were found to have malaria infection. Age group (0-5 years) had the highest frequency rate of 84.7% with mean parasite density of 900 and the difference between the age groups was statistically significant (p<0.05). Children of illiterates from suburb villages had the highest mean parasite density of 850 with 78.1% prevalence rate. 20% of the children were given local herbs and 22% used orthodox medicine as prophylaxis. Only 18% used insecticide treated mosquito nets while 24% of the parents spray insecticides to prevent mosquito bites. There is therefore need for more awareness on effective use of drugs and Insecticide Treated bed nets in malaria hyperendemic regions
