ABSTRACT:

This work was carried out at Jigawa Research Institute Biotechnology Laboratory Kazaure to determine callus induction potentials of 16 wheat genotypes using matured embryo as ex-plant source under different (PEG) levels. The experiment had six treatments (0%, 5%, 10%, 15%, 20% and 25%)
including control with each replicated three times and the necrotic percentage taken showed varieties 8(53.3%), 7(60%) and 28(61.1%) had minimal necrotic callus, while ANOVA shows that there is significance
difference between the treatments percentage values (P<0.05), while there was positive correlation among the genotypes. Also the total number of callus recorded for each variety across treatment showed an
encouraging callus production in varieties 8(38), 7(34), 2(32) and 6(31), however (ANOVA) shows significant difference between the treatment mean values (p< 0.05) while Pearson correlation coefficient among the genotypes indicated that there was positive correlation.

ABSTRACT:

This is a cross-sectional study involving 308 elderly participants, aimed at investigating the burden of ocular morbidity among the elderly population of Nyanya, Abuja. Their ages ranged from 40 to 70 years with a mean of 55.01(SD ± 11.39), the minimum age was 40 and the maximum age was 89. In the data collection, convenient sampling method was used. A comprehensive examination consisting of visual acuity testing, anterior and posterior segment examination was carried out on all the participants.
Refraction was done where necessary. Presbyopia was not considered for the analysis, because presbyopia is common among this age group. Intraocular pressures (IOPs) were checked for cup disc ratio >0.6 or where
there is 2D difference between the two eyes and when there is synechia. Glaucoma suspects were referred for perimetry. Visual impairment was classified according to the World Health Organization. Data were analyzed with statistical package for social sciences (SPSS version 25). From the result, the ratio of males to females is 1:1.08. Ocular morbidity was not significantly dependent on gender (P<0.05) but was significantly dependent on age (P<0.05). The most common ocular morbidity was conjunctivitis(15.3%, n=47 ), followed by refractive error (13.3%, n=41),other patterns are pterygium and refractive error
(10.7%,n=33),Cataract (9.4%,n=29) normal/presbyopia(9.4%, n=29),dry eye(7.8%,n=24), pterygium/ pinguecula + dry eye (5.5%, n=17), corneal ulcer (4.5%,n=14), uveitis(3.9% n=12),lid disorder (3.2%, n=10), hypertensive retinopathy(2.3%, n=7), glaucoma(1.6%, n=5), cataract + pterygium + refractive error (1.6%,n=5), glaucoma +cataract (1.6%, n=5), diabetic retinopathy(1.3%, n=4),refractive error and dry eye (3.2%,n=10), glaucoma + refractive error (3.2%,n=10),pterygium(0.6%, n=2), conjunctivitis + refractive error(0.6%, n=2), retinitis pigmentosa (0.6%, n=2). In conclusion ocular morbidity was found to be high among the elderly in Nyanya hence, health education programsshould target the elderly specifically and the entire population in general, on the importance of regular and comprehensive eye/vision check.

ABSTRACT


This paper is predicated on the impact of training on staff development in an organization. The problem that necessitated this paper among others are high labour turnover, damages to the organization through increased costs of recruitment and selection which delays product and or service delivery, low morale amongst employees and inability of management to recognize the type of training that will lead to staff productivity. The objective of this paper is to find out whether there is significant relationship between
training and staff development in an organization. The paper covers Power FM, Bida which has a total of 36 staff. Both primary and secondary data were used in this paper. The secondary data were sourced from
books and previous work similar to this while the primary data were obtained from structured oral interview of the employees of the establishment before drawing conclusion. In our findings, majority of the
respondents agreed that inability of management to provide adequate training resources to cater for its staff needs will hamper development of the staff thereby leading to high employee turnover in the organization.
Most of the staff of Power FM Bida also submitted that the management of Power FM Bida is not doing much to support the training of its staff. They also believe that adequate training of employees will lead to
high productivity on their jobs. As part of the writers’ recommendations, management of establishments especially Power FM Bida, should ensure that their employees are well trained to spur them to greater
performance and increased productivity. Keywords: Impact; Staff Training; Development; Organization

ABSTRACT


Since the second half of the 1940s, the Middle East has experienced intense migrations. In 2005 alone, the region received a total of approximately 6 million refugees. Migration flows to and from the Middle East have been linked to nationalist movements and ethnic conflicts. However, these relations have received little attention from scholars. Scholarly work on migration in the Middle East that has been accumulated between the early 1950s and the late 1980s falls into two broad categories in terms of subject matter: Jewish migration to Israel and the Palestinian refugees, and migrations to labor-short countries of the Gulf and Europe. This paper has look at the new trends in the literature on migration in the Middle East and identified issues relating to the gender aspects of migration, population displacement and resettlement, return migration, and the relationship between migration and security. Although the field has made significant progress—the scope of the literature with respect to subject matter has broadened from the 1980s onward, and the methods used by scholars have become more sophisticated over the years—there are some shortcomings that need to be addressed. A number of important issues, such as citizenship or economic dynamics, remain unexplored. Since labor migrations to and from the Middle East are central to economic development, a focus on the evolution of migration may shed light on numerous relevant themes that need be central to help in addressing the issues of migration and peace in the Middle East by looking the crisis in middle east with human face and propose appropriate amicable solution of the crisis by entire global community to ensure the sustenance of justice and peace in the Middle East. Keywords: Migration, Peace, Insecurity and Displacement

ABSTRACT


Cost management functions to monitor costs and initiate corrective action to keep the costs within budget. Construction cost management act as a discipline medium throughout the life cycle of an infrastructural development for effective and efficient procurement process. Construction cost escalation in economic downturn is influenced by lagging economic indicators of GDP, inflation, foreign exchange rate, interest rate,
unemployment rate, balance of trade, corporate profit and income and wages. Economic downturn in Nigeria and its impacts on construction cost escalation has become a major problem to both the public and private sector, contractors and clients, as this has resulted in the increase in number of abandoned or delayed projects, difficulty in achieving cost
estimates, increase in dispute arising from contractual arrangement and loss of jobs by construction workers which has made developers hesitant to enter into construction contracts in which they cannot manage the long-term impact their investment (Savills, 2016). The overall impact of construction project cost management is to achieve value for
money and provide an affordable infrastructural facility. This paper aims to propose a framework for the management of construction cost escalation in economic downturn. Key words: Economic downturn, construction cost escalation, construction cost overruns, construction cost, Management and construction cost management framework

ABSTRACT


This paper examines the socio-cultural determinants of infertility and marriage instability among the natives of Onitsha. The objectives of the study were to examine the sociocultural determinants of infertility underlying marriage instability, the gender factors associated with infertility, the socio-cultural consequences of infertility and the societal
opinions about the infertile couples. In this research work, descriptive survey was used to accurately portray the socio-cultural determinants of infertility and marriage instability among the natives of Onitsha. Consequently, 199 questionnaires were distributed to the
individuals who have a close relationship with childless couples in Onitsha inland Town. The study employed descriptive statistics and chi-square to analyze the data obtained. It was found from the study that the cause of infertility cannot be attributed to supernatural causes. It was also shown that male and female gender contributes to infertility and marital instability is often a consequence of infertility. It was shown from the research that gender factors affect marriage instability. The study also found out that family members show disregard for infertile couples. It is therefore recommended that those facing the challenge of infertility should check out options available to them such as insemination or
intracytoplasmic sperm injection. However, if all attempts fail, couples should accept their condition and stay strong. Further sensitization, counseling, and awareness are needed so that childless couples or individuals are not discriminated against.
