EMOTIONAL INTELLIGENCE AND PRODUCTIVITY OF LIBRARIANS IN PUBLIC UNIVERSITIES IN NIGERIA: A CORRELATIONAL APPROACH

This study investigated emotional intelligence as correlates of productivity of librarians in Nigerian public universities. A correlational survey research design was adopted. The study population consisted of 1,254 librarians in public university libraries in Nigeria, from which 923 were selected using simple random sampling. The research instrument used was a self-developed questionnaire. The questionnaire validation was subjected to the scrutiny of the experts in the areas of the variables studied; it gave a reliability coefficient of 0.91 for Emotional Intelligence and 0.94 for Productivity. A response rate of 67.2% was achieved. Data were analysed using descriptive (percentage, mean, average mean and standard deviation) and inferential (Pearson Product Moment Correlation) statistics. The study revealed a significant relationship between emotional intelligence and productivity (r = 0.032, P < 0.05) of librarians in public university libraries in Nigeria. The study concluded that contrary to general belief, emotional intelligence and productivity levels of librarians in university libraries were high. It is recommended that university library management should continue to promote values that would improve emotional intelligence and productivity of its workforce.  Article visualizations

Seasonal distribution of major diseases among sheep and goats in selected sub humid areas in Nigeria

This study into the diseases responsible for the uneven distribution of goat and sheep in the sub humid areas in Nigeria as one of the major hinderances in sheep and goat production despite the potentiality of this region to sustain small ruminants. A survey of the types and causes of major diseases of small ruminants was carried out in Edo State of Nigeria which presents variants of climatic conditions that cut across the humid areas of Nigeria and Africa. The study covered a period of five years (1997‐2002) in three local government areas of the state. A total of 316 small ruminants’ cases of major diseases made up of 25 cases in sheep and 291 cases in goats were recorded. Pneumonia contacted by the ruminants was 17%, helminthosis was 10% and was 6% as the most predominated diseases that occurred during the wet seasons than the period of dry season. Mange was high during the dry seasons and seemed to be confined almost exclusively to goats. Statistical analysis using a three‐factor analysis of variance revealed that seasonal distribution of diseases was a significant factor (p<0.05), diseases and the type of the small ruminant that contacted the diseases were significant factor (p<0.05). Most of the major diseases were frequently contracted during the wet seasons. In the Humid areas, there is need to sensitize farmers about ruminants’ health care management programmes especially intensive feeding method during wet season and deworming during onset or immediately after the wet season against gastro intestinal parasites as well as the improvement of indigenous breed through semi intensive management system by the farmers.Key words: Diarrhoea related diseases, symptoms, seasons, sheep and goats, sub humid, veterinary records, Nigeri

Development Of Biodegradable Polyetheramide-Urethanes From Castor Seed Oil

Castor seed oil (Ricinuscommunis) is a vital renewable base material for industrial production of lubricants, brake fluids, soaps, inks, pharmaceuticals, pla stics, perfumes etc. The presence of reachricinoleic acid (about 87.5%) content in its fatty acids profile confers on its essential use for coating purposes. This paper presents the synthesis, characterization and antibacterial evaluations of polyetheramide-urethanes (PETAU) prepared from Ricinuscommunis seed oil. N,N'-bis (2- hydroxyethyl) Ricinuscommunis fatty amide (HERA) was synthesized via aminolysis. Upon reacting HERA with bisphenoiA, polyetheramide (PETA) resin was form ed. The polyetheramide subsequently undergo urethanation to form PETAU. The synthesized PETAU was characterized by FT-IR, 'H-NMR and 13C-NMR spectroscopic analyses. Selected physico-chemical parameters of seed oil, HERA, PETA, PET AU were measured. Coating performance, thermal stability and antimicrobia l properties ofthe cured resin were also evaluated

65The Nexus Between Talent Management and Organizational Commitment: An Empirical Evidence of a Private University in Southwest Nigeria

Sustainability of organizational activities depends largely on the commitment of the talented workforce involved. Talented employee’s organizational commitment lies on talent management practices embraced by the management of such an organization. This empirical study seeks to establish the relationship between talent management practices (talent attraction, talent development and talent retention) and organizational commitment (affective commitment, continuance commitment and normative commitment). Six (6) point Likert scale questionnaires were administered to the members of faculty of the University identified for the study. The data gathered were analyzed and results revealed positive significant relationships between talent management practices and organizational commitment. Talent development was identified by Friedman Rank correlation as the most predicting factor of faculty’s organizational commitment. It was thus recommended in the study, that management of organizations should create enabling environment through various strategies such as wage increase, good working condition and incentives etc., in order to combat the high rate of turnover confronting educational sector of the economy. Areas for further studies were also suggested

Quality assessment of Sandcrete blocks in Ibadan – A review

Sandcrete blocks have been widely used for modern building construction in Nigeria; however cases of incessant building collapse are rampant. The usage of substandard sandcrete blocks is a contributing factor. This research was carried out to assess the engineering properties of sandcrete blocks produced in Ibadan and its environs. Two blocks each of size 450 x 225 x 225mm were purchased from selected block industries at eight sampled locations within the study area. Few units of blocks (450 x 225 x 225mm) conforming to the Nigerian Industrial Standard (NIS 87: 2007) were also produced to serve as control samples. The 28th day dry compressive strength test result obtained for the sampled blocks ranges between 0.39-2.34 N/mm2. For the control block samples, the average 28th day dry compressive strength of the three tested blocks was 3.02 N/mm2. Conclusively, it was observed that the sandcrete blocks produced in major parts of Ibadan were of low quality and substandard; while the control samples were of adequate strength

Crack Mechanism of Different Concrete Grades under Compressive Loading: Application in Rigid Pavement

The growth of cracks in concretes under different loadings in various structures and their consequent diminishing effect on the lifespan of structures is an age long structural problem. This research investigates the influence of compressive loading on the crack mechanism of different concrete grades 1: 1 : 3 (M20), 1: 2: 4 (M15) and 1: 3: 6 (M10) using three brands of cements available in Nigeria namely Dangote (Type A), Elephant (Type B) and Bua (Type C). Particle Size Distribution (PSD), Aggregate Crushing Value (ACV), Aggregate Impact Value (AIV) was carried out on aggregates in accordance with relevant codes while; compressive test were performed on the hardened concrete while, the crack width was measured using microscopic technique. A coefficient of uniformity (Cu) of 4.00, AIV of 46 % and an ACV of 47.7 % were obtained for the aggregate which are suitable for rigid pavements construction. Maximum compressive strength value of 24.96 N/mm2 , 24.67 N/mm2 and 24.89 N/mm2 respectively was obtained for concrete M20 for Type A, Type B and Type C cement at the 28 day. A corresponding crack width of 0.97 mm, 0.89 mm and 0.93 mm was obtained while; a yield period of 57.66 sec, 58.33 sec and 53.33 was obtained respectively. Comparing with the International Organization for Standardization, concrete grade M20 any of the cement types is suitable for the construction of rigid pavements with heavy traffic volume while M15 is recommended for low traffic volume

Hysterosalpingography findings among women presenting for gynecological imaging in Ado-Ekiti, South western Nigeria

Background: Hysterosalpingography (HSG) is a valuable radiological procedure for imaging the female reproductive tract. This study highlights the spectrum of HSG findings among women presenting for gynaecological imaging in a tertiary health institution in Ado-Ekiti, South western Nigeria.Methods: A prospective cross sectional study was conducted between October 2014 and September 2015. The study population consisted of 134 women presenting at the Radiology department with request forms for HSG. Pelvic ultrasonography was done using a 3.5MHz transducer prior to HSG. Imaging findings were documented, results were entered into a spread sheet and analysed using SPSS version 20. Chi square was used to determine association between tubal occlusion, age, type of infertility and previous history of surgery. Statistical significance was set at p-values <0.05.Results: The age range of the study participants was between 23 to 50 years with a mean age of 34.9±5.53years. Age group 30-34 years (n=43, 32.1%) constituted a majority. Secondary infertility (n=84, 62.7%) was the most common clinical indication for HSG. The predominant relevant past surgical history was uterine evacuation (n= 41, 30.6%). Normal HSG findings were seen in 34 (25.4%) of the patients while others (n=100, 74.5%) had various abnormalities, the most common of which were tubal pathologies (n=89, 66.4%). There was a significant association between age and tubal occlusion (P=0.02).Conclusions: HSG is still a relevant gynecological imaging modality in resource limited settings. Tubal occlusion was the most common abnormal HSG finding in this study. There is a need for continuous advocacy on preventive measures targeted at reducing the incidence of tubal pathologies among women in developing countries

Effects of vigabatrin, carbamazepine or its combination on the pituitarygonadal axis in male Wistar rats

Objectives: Epilepsy is the most common non-infectious neurologic disease in developing African countries following stroke and Alzheimer's disease. Most conventional antiepileptic drugs, due to their centrally acting potentials have been implicated in the deregulation of reproductive hormones. This study assessed the effect of the single and combined administration of vigabatrin (VIG) and carbamazepine (CBZ) on the pituitary-gonadal axis of male Wistar rats.Methods: Fifty male Wistar rats were randomly divided into 5 groups (n=10). The animals were administered with distilled water (0.1 ml/kg/day), VIG (200 mg/kg/day), CBZ (200 mg/kg/day), VIGCBZ combination (100 mg/kg/day each) and VIG-CBZ combination (200 mg/kg/day each) for 8 weeks. Twenty-four hours after the last dose, 5 rats from each group were sacrificed, while the remaining 5 eventually sacrificed after another 8 week of drug withdrawal. The level of luteinizing hormone, follicle stimulating hormone and testosterone were determined from the serum. The weight of the reproductive organs and sperm indices were assayed, while the testicular tissue were examined for signs of histological alteration.Results: The results showed significant decrease in the levels of luteinizing hormone, follicle stimulating hormone, testosterone and sperm physiological indices. Morphological alteration was noticed in the testes of all the treated rats. However, there was restoration of these parameters sequelae to 8 weeks cessation of treatment.Conclusion: Single and combined administration of VIG and CBZ resulted into pituitary-gonadal axis hormonal deregulation and alterations in the sperm profile which were however reversible upon cessation of treatment.Keywords: epilepsy, vigabatrin, carbamazepine, sperm, testosteron
