The structural integrity of engineered structures depends highly on the materials used. In recent times, increase in the collapse of buildings in Ghana has allegedly been attributed to the poor engineering properties of locally produced steel rebars, an indication that they do not meet the requirements set by the Ghana Standards Authority (GSA). This project studied the metallurgy of different rebars randomly sourced in Ghana, with a view to determine their suitability for structural applications. The study involved determining the chemical composition of the various diameters of rebars, analyzing microstructure and mechanical properties of the rebars and the obtained results compared with GSA values. The diameters measured gave average values which were close to that of the standard values. The chemical compositions of the rebars were good as they were all within the mild steel range but a few noticeable inconsistencies were observed in the chemical composition. The average tensile and yield strength for the samples were 545.11 MPa and 453.55 MPa which were above the GSA values of 400 MPa and 300 MPa minimum respectively. The rebars were quite ductile as standards for both elongation and area reduction were exceeded. This showed that the selected rebars met the GSA standards.
The study investigated perceived influence of deviant behavior on the academic performance of students among senior secondary schools in Awka South Local Government Area of Anambra State. The study adopted descriptive survey research design and was guided by four (4) research questions. The population of the study comprised 12,813 secondary school students in 26 public and private approved schools in Awka South Local Government Area of Anambra State. Sample size of 200 was used for the study. Multi-stage sampling procedure was used. The instrument used for data collection was a structured questionnaire titled PIDBAPQ with 4 points Likert scale. The reliability index was obtained using test re-test method and scores collected were subjected to Pearson product moment correlation and a value of 0.75 was obtained, showing that the instrument is reliable. The results reveal that secondary school students perceive that there are deviant behaviors exhibited by students of senior secondary schools in Awka South Local Government Area, students perceive that there are many causes of deviant behavior among senior secondary schools, students perceive that deviant behaviors have effects on the academic performance of students among senior secondary schools, students perceive that there are different strategies for managing deviant behaviors in order to improve students’ academic performance among senior secondary schools. Recommendations made included; Principals and teachers should device appropriate punitive measures in controlling deviant behaviour in schools, teachers are urged to also seriously consider some form of interactionist approaches like guidance and counseling when dealing with cases of students’ misbehavior. Principals should also ensure that they regularly admonish students during morning assembly on good conduct as school authorities should occasionally invite moral transformation agents to school to give talks to students on good moral behaviour.
This study examined the degree of relationship between organizational culture and organizational paranoia in construction companies in South East, Nigeria. The study adopted survey research design using modified standardized structured questionnaire to elicit data. The population was obtained from selected construction companies during field survey. Systematic sampling technique was adopted in selecting four (4) construction companies from the region. The sample size and number of units allocated to each construction company was determined using Taro Yamane and Bowley's Proportional Allocation Formulae respectively. Spearman Rank Correlation was used to test the formulated hypothesis on the platform of Statistical Package for Social Sciences (SPSS) Version 21.0. The finding revealed a positive significant relationship between organizational culture and organizational paranoia in construction companies in South East, Nigeria. The study, therefore, recommends that organizations need to entrench acceptable norms and values in the system that would leave all stakeholders satisfied to reduce fear, anxiety, suspicion, and distrust. Organizations need to foster a work environment and climate where lackadaisical behavior is unacceptable.
Bangladesh is an agriculture based country of which dairy sector shares a large economy and meets a great portion of the protein requirement of its population. Friesian crossbreds are highly recommended and beneficial to rear for dairy farms in the aspect of Bangladesh. The present study determined the parity effects on Local-Friesian cross-bred dairy cows’ production and reproduction performance at the Central Cattle Breeding and Dairy Farm (CCBDF), Savar, Dhaka. 77 individuals were selected for this study and the quantitative data (Gestation period, Lactation period, Milk production per day, Calf birth weight and Calving interval) from the existing database (2008 to 2019) was recorded. Kruskal-Wallis test was conducted using STATA-13 statistical software to evaluate the association between parity number and each of outcome variables (Gestation period, Lactation period, Milk production per day, Calf birth weight and Calving interval). The results of each production and reproduction outcome varied significantly by parity number (p≤0.003) except for the gestation period (p=0.22). The obtained median of the gestation period for 1st to 6th parity was 276-279 days without the trend of increase or decrease in relation to parity. There was decreased calving interval (median from 1st to 6th parity, 529.5-375.5 days) and lactation period (median from 1st to 6th parity, 361.5-270 days) and increased milk production per day (median from 1st to 6th parity, 5.2-8.6 liter per day) and calf birth weight (median from 1st to 6th parity, 23-28 kg) with increased parity number. The results indicated that the cattle performance at Central Cattle Breeding and Dairy Farm was satisfactory. It was concluded that should explore the source of the short lactation periods further, as it is an important economic factor for dairy farms. Along with the genetic background of the dairy cows, some environmental factors (climate, year and season of calving) and management factors (disease control and feeding status) should be considered for investigating the reasons for the short lactation period.
I draw a distinction between traditional literary interpretation, which makes assertions which suitably informed readers are expected to accept on the basis of a kind of intuition, and subversive interpretation, which aims to present a counterintuitive interpretation of a text which fits with the evidence. Traditional literary interpretation faces objections of being unscientific and undemocratic. Subversive interpretation may appear as a solution, but it is so difficult to successfully use this approach that it is questionable whether it solves the objection of being undemocratic.
