Ethical communication issue of trustworthiness and its impact on organizational efficiency of the nigerian immigration service, rivers state

Abstract: This paper was an expository study of how communicational ethical issues such as trustworthiness impact organizational efficiency of immigrations service in Rivers State. The objective of this study was to assess the relationship between trustworthiness and organizational efficiency. Questionnaires were the major instruments used in gathering primary data and findings were analysed using regression and correlational analysis. The study found that trustworthiness as an ethical communication tool significantly relates to the efficiency of the Nigerian Immigration Service in Rivers State. Trustworthiness is communicated by the display of acts or behaviours which are considered worthy. The study concluded that communicational ethics whose values in this study were established as trustworthiness significantly relates to efficiency-factors of time saving and cost reduction. The Nigerian Immigration Service was found to lack the efficiency-driven values as revealed in this study and as such must be repositioned to reflect these essential values to enable it compete more favourably. The study recommended that in order for immigration services to maintain their ethics in River State, the Federal Government should overhaul the Immigration Service with a view to enthroning the culture and values of communication ethics; Officers who had maintained high ethical standards should be publicly commended and rewarded accordingly; also officers with sound ethical records and orientation should be appointed into the members of Ethics and Disciplinary unit of the Service and Ethics and Disciplinary unit of the Service should evolve a realistic method for checkmating unethical and sharp practices and behaviours among the officers.

Development of Mathematical Model to Predict the Quantum Energy of an Electron in an Orbit of Hydrogen, Lithium and Sodium

Abstract: The basic particle electron obeys various theories like electrodynamics, quantum mechanics and special relativity. Particle under different experimental conditions behaves differently, allowing us to observe different characteristics which are the basis for this work. In this paper, we have made an attempt to predict the quantum energy of an electron in an orbit using hydrogen, lithium and sodium atom as a base. As it is ‘difficult’ to find structure of electron experimentally, we make a mathematical attempt to predict the quantum energy number of an orbit when not in motion, we have studied atoms with same number of orbits, different atomic numbers and discovered that an increase in orbits has a major effect on the energy level of an atom also energy differs in different orbits. An attempt has been made to give a model that predicts the quantum energy of an electron in an orbit, the focus of these work is to develop a mathematical model that can predict quantum energy of electron in an orbit.

A Bill of Rights as the Basis of a Common Law in a Pluralist Nigeria

Abstract: I shall argue in this paper that Nigerian common law should be a synthesis of the received English law and customary law including Islamic law with the fundamental human rights contained in chapter four of the 1999 Constitution of the Federal Republic of Nigeria providing a credible basis and framework. I will urge that since it represents a set of enforceable values, it provides a framework for the growth of a Nigerian common law. Part of this framework is the balancing of rights inherent in a human rights system and the derogation of certain human rights which make it possible that different nuances, values and aspirations prevalent in Nigeria can be accommodated. I point out that the proof of customary law including Islamic Law as a fact and their validation by means of the repugnancy and public policy tests have denigrated and humiliated these laws making them play second fiddle to the received English law thereby stifling their growth and that of the common law. Against this background, I argue that Nigerian common law based on a Bill of Rights will have nothing to do with the validation tests of repugnancy and public policy since it is a test in itself and will treat the received English law and customary law including Islamic Law on the same pedestal such that the jurisprudence of each law will be assessed on its merit. I note especially, the immutable nature of Islamic Law, the strong claim that it is not customary law; the codification of Islamic criminal law principles as State Law and urge that Constitutional supremacy and superiority mandate accommodation within its framework. All through the paper, I examine how principles of customary law and customary law can and should influence the development of the Nigerian common law; just as its principles are subject to the values enshrined in the Bill of Rights. In undertaking this analysis, I acknowledge the deficiencies of judge-made law in revolutionizing legal systems and recognize that a unified administration of justice; the study of customary and Islamic Law and appropriate legislation will complement the development of Nigerian common law.

Population dynamics and age-dependent mortality processes in tropical reptiles

Abstract: Understanding age-dependent mortality processes is a critical challenge for population biologists. Actuarial senescence appears to be a common process across the tree of life. Senescence patterns are highly variable in pluricellular organisms: senescence can be gradual or sharp and its onset may be early or delayed. By contrast, studies revealed that organisms may also not experience senescence at all while others display a “negative senescence”; i.e. a decrease of mortality rate with age. To date, studies on senescence have largely focused on human and other endotherm vertebrates, limiting our understanding of senescence in amniotes as a whole. By contrast, few have examined the diversity of senescence patterns in ectotherm vertebrates as reptiles. Here, we examined population dynamics and age-dependent mortality patterns in three tropical tortoises (Kinixys erosa, Kinixys homeana, Kinixys nogueyi) and snakes (Bitis gabonica, Bitis nasicornis, Causus maculatus). Our study revealed that tortoises of Kinixys genus had a higher survival and a lower recruitment than snakes of the genera Bitis and Causus, indicating that they have a slower life history. Furthermore, we showed that survival more slowly decreased with age in tortoises than in snakes. In addition, we highlighted contrasted patterns of age-dependent mortality in the three genera. In Kinixys, the relationship between mortality rate and age was positive and linear, suggesting gradual senescence over tortoise lifetime. By contrast, the relationship between mortality rate and age was negative and sharp in Bitis and Causus, possibly due to a “negative senescence” starting early in life. Our study highlighted various age-dependent mortality patterns in tropical reptiles. It also contributed to extend our knowledge of senescence in ectotherm vertebrates whose the demography is still poorly understood. In addition, while negative senescence has never been reported in endotherm vertebrates, our results showed that it can be common phenomenon in ectotherms.

Analysis of Uniformly Loaded Simply Supported Rectangular Plates with Lifting Corners Using Strip Moment Ratio (SMR) method.

Abstract: The application of the SMR to rectangular plates with corners allowed to lift is presented in this paper. The classical plate bi-harmonic equation for rectangular plates was adapted to the problem. It is assumed that the load on the plate is supported by the joint effort of transverse x-x strips and the longitudinal y–y strips only. The effect of the two diagonal x–y strips required for holding down is neglected. The effect of Poisson ratio on the span moments and plate’s deflection is also presented. The indication is that an increase in Poisson ratio brings about an increase in the longer span moments of the plate and has got no significant effect on the shorter span moment and deflection of the plate. The results of practical application show close agreement with the exact classical results. Keywords : Plate, strip moment ratio, SMR, plate deflection and Plate moments, Lifting Corners.
