With changing policies and the resulting emphasis on female education, the ground is shifting as many women have entered previously male-dominated fields such as medicine, law, politics, the academia, among others. However, women still must pass some sociocultural and institutional hurdles to be able to attain a meaningful level of growth in their chosen careers. Despite the progress that women in the professional sphere have made, they remain underrepresented in strategic and essential positions. In fact, in academia, the representation of women can be likened to a pyramid where only a very small and, indeed, insignificant number of women exist at the top and in key leadership positions, especially in Nigeria. This position also applies to Prince Abubakar Audu University and Veritas University, Abuja, by implication. In this research, we have adopted the doctrinal approach and found that women still have a long way to go compared to men in attaining leadership roles. More work needs to be done collectively by men and women to place women in the leadership scheme.","PeriodicalId":14101,"journal":{"name":"International journal of innovative research and development","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87851261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of these variables is bearing clearance. However, there is limited information on the influence of bearing clearance on surface integrity. This paper is an optimization study in which the surface roughness of AISI 1018 mild steel is minimized with the aid of the response surface methodology. In this paper, the effect of process parameters like cutting speed, feed, depth of cut, and bearing clearance is analyzed to ascertain how the surface finish properties of mild steel can be improved. The design of the experiment used for this study involves a rotatable central composite system. This design is used to find the experimental results of machining. The analysis of variance (ANOVA) was used to determine the statistical significance of the improved quadratic model developed. The numerical and graphical optimization carried out determined the optimum values of each of the parameters used in different ways. From the ANOVA, it was revealed that the most significant factor in the model was the depth of cut. This factor was closely followed by spindle speed, bearing clearance, and feed, respectively. Numerical optimization results employing the desirability function showed optimum values to be at bearing clearance of 70um, depth of cut of 2.5mm, feed of 0.01mm/rev, and a spindle speed of 450rpm. The result obtained using the graphical optimization option was similar to the results from the other options. The variation of surface roughness with the process parameters chosen for the experiment was mathematically modeled. The model developed used the response surface methodology, and it was validated with a set of experimental values. The result from the exercise undertaken revealed that the predicted values of the surface roughness were very close to measured values. The average percentage deviation of 6.20% for all sample data utilized showed that the model developed was in close agreement with the experimental results.","PeriodicalId":14101,"journal":{"name":"International journal of innovative research and development","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73612853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, initially, we carry on a comprehensive evaluation of more frequently used statistical methods for evaluating Stock markets. Our work is based on collecting 40 years of data from the Italian stock market. The proposed solution is defined using the statistical analysis of the Bear and Bull Stock markets. We defined a new system to predict the trend of a stock market price, where the trend of the succession of Bull and Bear markets can be described by a probability density function given by a Gaussian distribution. Furthermore, we consider the inverses of the relative time intervals as a measure of the speed with which the phenomenon of the Bear market (or, equivalently, the Bull market) develops in that interval of time. Therefore, this factor can ultimately represent the first statistical weight of the single percentage variation. Again, the time intervals of the individual Bear and Bull market periods are considered, calculated from 01/01/1973. This allows us to consider the hypothesis that a secondary factor of probability is the temporal distance of the event that has already occurred. This work includes a criterion for statistically generating the most probable values of the next Bear and Bull markets and the length of the time intervals corresponding to these market situations. This criterion is based on the following hypothesis: \u0000To obtain the distribution of the predictive points of max and min in the succession of Bull and Bear markets, it is assumed that, in the long period, the random distribution of the successive max and min takes the trend of the distribution of the distance fluctuations between the zeroes of the Riemann's function which, in turn, is approximated by a Unitary Gaussian Distribution (GUE). Our results show that: \u0000 \u0000The linear interpolation of the Variations of the market (positive and negative) relative to different and successive sampling sets for future trends do not show high percentage variations between them, \u0000Above all, the lengths of the single time intervals of the future variations, relative to different and successive sampling sets, are quite similar to each other. Hence, the method appears to be basically stable and promising. \u0000","PeriodicalId":14101,"journal":{"name":"International journal of innovative research and development","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74253931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve these, the research examined the essential roles of Intellectual Property in the growth and development of Small and Medium Sized Enterprises. The rights and remedies to which the owners of Small and Medium Sized Enterprises (SMEs) are entitled, as well as the challenges of Intellectual Property Laws and their corresponding tax liabilities under the relevant pieces of legislation in Nigeria, are considered. This research evaluates the factors contributing to the non-compliance of SMEs with tax obligations. These include complex filing procedures, multiple taxations of SMEs, and a lack of proper enlightenment. The finding reveals that SMEs have performed below expectations due to specific reasons ranging from societal constraints to issues of lack of awareness, instability, and change in the economy. Tax compliance among SMEs in Nigeria is poor. To enhance the growth of Nigerian SMEs, there is a need to explore enlightenment and awareness through the use of intellectual property and taxation.","PeriodicalId":14101,"journal":{"name":"International journal of innovative research and development","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74267053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is common to all well delivery operations in the oil and gas industry, including drilling, completions, work-over, and abandonment. \u0000Besides drilling a well that meets technical specifications in a safe manner and within the approved budget, well delivery success is not achieved if the specified time is exceeded. Time is an essential factor as it also has a large influence on cost. Well delivery time could be classified as either drilling time (time allotted to activities where the well depth increases with time) or flat time (time allotted to activities that do not directly contribute to an increase in well depth). \u0000Flat time reduction is a key strategy used to reduce oil and gas well delivery costs. This is applicable in drilling operations, specifically where well cost is directly proportional to time. There is ample room for drilling performance improvement by reducing flat time without eroding well quality. Oil and gas well delivery performance engineers are, therefore, constantly seeking ways to reduce flat time to the barest minimum. \u0000Tripping optimization refers to the application of specific methods aimed at preventing technical issues while tripping and reducing tripping time. Tripping is one of the major contributors to flat time, with typically circa 8 to 10% of planned tripping time (exclusive of casing and completion running time) in drilling operations. This means tripping optimization has a direct effect on flat time reduction and, by extension, well cost reduction. \u0000This article discusses various tripping optimization techniques and how they promote flat time reduction in oil and gas well drilling operations. It emphasizes how drilling operations can be more time-efficient and consequently cost-efficient by improved tripping practices.","PeriodicalId":14101,"journal":{"name":"International journal of innovative research and development","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84603940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 80 student respondents currently attending tertiary institutions in Uasin-Gishu and Trans-Nzoia Counties in Kenya were interviewed using an on-spot questionnaire. The findings indicate a near 'fanatical,' 'nostalgic,' and 'emotional' attachment of the student respondents to almost all the various subordinate support staff they interacted with in their formative educational years. Respondents enrolled in boarding schools at an early age reported strong 'emotional' and 'social support' from especially matrons, cooks, and drivers who acted primarily as caregivers. The relationship between students and subordinate staff developed to the extent of students assigning 'nicknames' to some of them. In one of the primary and secondary schools, the school bus was assigned the names 'monkey cage' and 'Lucy.'
