The use of waste as an additional material on the building work was increasingly actively developed, such as straw, styrofoam, bagasse, cow manure. The key drivers of the use of waste is the potential for waste is increasing, due to the depletion of non-renewable resources. Papyrus rod diameter 60 cm, length 30 meters, has a volume of 5,652m3 as well as the edges of the Rods that can be used for construction with a thickness of 3 cm has a volume 0,942m3, Pith and fiber volume content of the stem 4,71m3/rod, then in one rod, there are 2 to 3 bunches each fruit bunches yield as much as 20 to 30 items for one harvest, by weight of fruit fiber 101.2 gram / fruit, Fiber characteristics are round and smooth is expected to reduce cracks in solid concrete brick and also can reduce the use of sand. This study aims to determine the compressive strength of the composition of the additional material of Rods fiber content and Fiber of palmyra fruit with a percentage 3%, 6% and 9%, mixing ratio; 1 cement and 5 sand in the manufacture of solid concrete brick. Rods fiber content used the average Ø1,031mm with a tensile strength of single fiber 39,305N / cm and fruit fiber to an average value Ø0,40mm with a tensile strength of single fiber 33,691N / cm. Making test specimen with a length of 20cm, width 10cm and thick 8cm. The test results of compressive strength after 14 days with the lowest value at 3% of additional material combination of fiber content of 6% fiber stem and fruit by 70,384Kg/cm²with a water content of 15,254% In weight position 2,935Kg as well as the highest value on the combination of additional material 0% rods fiber content and 3% fruit fiber by 98,821Kg/cm² with a water content of 15,031% In weight position 3,058Kg. While N (without additional material) with a compressive strength below the average id 63,704Kg/cm2 with water content of 10,167 in weight position 3,072Kg. Research result of solid concrete brick with additional material of rods fiber content and palmyra fruit fiber was included on the type B70, the average value of the compressive strength of 78.57 Kg / cm² (SNI-03-1348-1989) with a water content of <25%.

Abstract

Communication is not a reaction to something, not an interaction with something but a transaction inwhich man invents and attributes meaning to realize his purpose. It should be stressed that meaning issomething invented, assigned and given rather than something received. It is the production of meaningrather than the production of messages that identifies communication. Organizational communication istherefore the flow of materials, information, perceptions, and understanding among the various parts andmembers of an organization. In an organization, a lot of consideration is made on the lines ofcommunications, strategies to be used, technological facilities provided and the communicator shouldknow and understand the different ways with which to communicate with the people in and outside theorganization to effectively achieve their goals. kazt and kahn (1966,p.12) found out that managers in anlisted oral communication and listening as the most important skill for gaining employment and improveworking relationship and even any kind of relationship requires open and accurate lines of communicationand only when such lines exist will one feel free to voice out important feelings and thoughts. This paperfocuses on how effective organizational communication is in this global economic age.

Abstract

This paper reviewed the Human Capital Development in Science and Mathematics in Nigeria. The teacherhas been identified as the most important factor in meeting the Human Capital Needs of Nigeria inMathematics, Science and Technology (MST). Thus the country’s goal of becoming one of the 20 greatestcountries of the world by the year 2020 must adequately focus on the teacher. The Teaching Profession isat the peak of all professions - it is the profession that creates other professions. All the efforts of theFederal Government of Nigeria, STAN, MAN, and other organisations have not eradicated the acuteshortage of mathematics and science teachers. It is recommended that putting back the TeachingProfession at the pinnacle it used to be in Nigeria (The Teaching Profession is at the pinnacle and hasalways been at the pinnacle in other parts of the world), will check the exodus of trained teachers. Thisway, the leakages being experienced in the profession would be eliminated and the Human Capital Needsof Nigeria in Mathematics, Science and Technology met with minimal efforts.

Abstract

It is no news that Nigeria is a blessed country with both human and natural resources with a land area of983,213kms and over 120 million people, as expected though with its own fair share of challenges andopportunity yet unaddressed owning to which the services of management practice becomes eminent andbrings to bear the need for this paper on the challenges of managing in the Nigeria work environment.These challenges were viewed in two perspectives, external and internal with individual peculiarities.Handling our work environment demand collective effort, owing to which the skills of managing play agreater role within the said system. It is our believe then, that we create an institution which promote anideal working environment that captures a more collective interest and speak of collective vision with thebig picture in mind of today’s issue with the focus on tomorrows challenge. A glance at Nigerian workersshows motivational problems which is traceable to the variety of circumstances as notice in the variousenvironments. These challenges can be addressed by both management and government to introduceuseful and lasting measures, practices to stir the sea of management to meet its “big picture”.

Abstract

The main objective of conducting this study was to examine and analyze, in the context of Bette-Bendipeople of Cross River State, Nigeria, the relationship between political violence and secondary schooleducation and test for causality between them. Bette-Bendi people, who are in the volatile Niger Deltaregion, were used as case study. Three research questions and three null hypotheses were formulated toguide the research. Data gathered were analyzed with the x2, v-statistic and factor analysis involving fifteenvariables. All three null hypotheses were rejected in favour of their alternatives. The main finding confirmeda strong relationship between political violence and secondary school education. The study concluded thatthe Nigerian government should set up a Committee of Experts to develop a Survivalist Curriculum in linewith the work of Academic Associates Peace Works in Taraba and Delta States as the most ideal forsecondary school education in Bette-Bendi and all politically violent and unstable areas for a permanentresolution of crises and behaviour control in those areas throughout the country.

Abstract

The world of today is predominantly shaped and controlled by the overwhelming influence of science andtechnology with the study of mathematics as a pivot. This is perhaps in recognition of the indispensablerole of mathematics in realizing the nation’s dream of rapid scientific and technological development. Thisalso portends the fact that the triangle of science, technology and mathematics should be vigorouslypursued by the Nigerian government. However, Nigeria’s effort to promote scientific and technologicalliteracy are not yet yielding the required dividends because basic strategies for teaching mathematics havebeen down-played by various government agencies. Despite the bare fact that Nigerian children still shyaway from the study of mathematics, issues in mathematics teaching strategies such the use of qualifiedteachers, teacher motivation by incentives and computer aided instructions should be adequatelyimplemented. This paper addressed the issues of strategies for teaching and sustaining mathematics as anindispensable tool for technological development in Nigeria. Some innovative teaching strategies weresuggested for demystifying mathematics in the Nigerian classroom. They include the strategy ofconstructivism, groupings into students’ ability and the use of instructional aids and games. The paperconcluded that if the various strategies of stimulating the interest of students in the teaching and learningof mathematics are put to use in any country, including Nigeria, a great deal of change may be seen.

Abstract

Corruption, in any way it is looked at, is a social-cankeworm as it pays no person, party government,institution and the society any good. Corruption is manifested in every phase and sector of the Nigeriansocio-political economy but it is more pronounced in the petroleum sector in the country. Because Nigeriaso much depends on the petroleum sector as her sources of living, income, economic growth anddevelopment, any corrupt practice in the sector by any person or party automatically affects all othersectors of the economy. Efforts have been made by both the past and present governments throughlegislative, executive and legal frameworks as well as administrative; to reduce corruption in the sector butit seems that not much has been achieved to drastically reduce this social vice in the Nigerian society. It istherefore suggested here that a combined effort of all stakeholders in the oil and gas business – the federaland state governments, the judiciary, legislature, law enforcement agencies (the ICPC, EFCC, immigration,customs, police, army, air force, navy, civil defence corps, etc) as well as the Nigeria National PetroleumCorporation (NNPC), the oil multinational companies in Nigeria, the oil markets and internationalcommunity and other agencies like UNDP, World Bank, IMF, etc- should be the only way out to wipecorruption out of the country. The only way is through transparency and proper accountability in alldealing in the sector.

Abstract

Leadership and followership are very essential factors for national development and achievement oforganizational goal. Leadership and followership is a major universal challenge to all nation States; whilesome countries have overcome the primitive or dictatorial stage to propel their economy and social welfareof her people to a comfortable level; other emerging developing economy are still reeling to grow abovethe challenges of impotent leadership and followership syndrome. This paper discussed Leadership from themacro level. It looked into the concept of leadership, Types, qualities, functions and problems of leadershipfrom the Nigeria perspective and the relationship between Leadership and followership. The paper is aimedat enlightening political leaders and their followers of their responsibilities, and promoting goodgovernance in Nigeria. This paper recommend that, leadership and followership relationship should alwaysbe harmonized as to enable the society or group to achieve her vision and set goal. Leadership andfollowership should adopt a new paradigm shift were values, and leadership traits, integrity and otherdiscussed qualities herein will serve as the basis for consideration or conceding Leadership. Consensusselection of leaders should be avoided; Leaders should be elected through democratic and transparentprocess. Tribal sentiments should be set aside in electing and criticizing our leaders. Our target and criteriafor assessment should be our vision and goal as a people.
