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.

Abstract

The integrative research was done with participatory action research with Participatory Appreciate-Influence-Control technique(PAIC) and qualitative research with focus group discussion. The sample was selected according to purposive samplingtechnique. The PAIC was implemented with 38 community leaders who came from community that faced with flood disaster in2011 from Kuntarawichai District in Mahasarakham Province with brain storming integrated in focus group discussion duringthe training process. During training, Three Dimensional Evaluation (TDE) covers Self-evaluation, Friend-evaluation, andFacilitator-evaluation. One -Way-ANOVA, and Paired t-test were used for data analysis. The research results illustrated thatbefore and after PAIC process implemented the posttest mean scores of knowledge of environmental education principle,natural disaster from flood disaster, flood response behavior and training achievement score were higher than pretest withstatistical significance (p&lt; .01, p&lt; .01, p&lt; .01, and p&lt; .01). Three Dimensional Evaluations were employed for determinationthe perceptions of 38 community leaders in three aspects evaluation covering Self-evaluation, Friend-evaluation, andFacilitator-evaluation by using One-way ANOVA in order to investigate the participation of peoples and the result showed thatthere were no difference of mean scores for participation in training process in past, present and future situations withstatistical significance (p&gt;.05, p&gt;.05, and p&gt;.05). Moreover, supervising, monitoring, and evaluating for flood responsebehaviors, it was found that the community leaders set plan and hold meeting with community peoples to implement project forlife safety with preparation of communication equipment, boat, food, water, drug, and place for living including establishing thecommittee for surveillance, warning, and support from involved work unit. Moreover they hold program of disaster exercise tomove to safety place at good and very good levels in all aspects.

Abstract

This paper discusses the hyphen and buckle between democracy and development in Africa with specific focus on theNigerian State. Its major focus is anchored on the positive transformation of the standard of living of the people. Thistransformational change in the lives of the Nigerian people was unfolded through the factorial analysis of the concepts: poverty,quality of governance cum political participation and national integration. The conception and argument of the researcher isthat democracy as a political mechanism for development has witnessed minimal or no qualitative transformation in the lives ofthe people as it pertain poverty reduction, political participation and national integration as a result of poor governance. Thus,the researcher recommends that if democracy is to positively impact on development especially in the Nigerian State, there isneed for the present democratic system to be restructured in such a way that the system is largely integrative of the peoplethrough their involvement in policy or programme initiation at the party level, communal and national level. Coupled with theabove is the need for vibrant political opposition that would provide functional alternatives to issues that borders on poverty,performance and national integration.

Abstract

This research's objective is to highlight the multidimensional determinants of FDI in Central Africa countries, especially in theEconomic and Monetary Community of Central Africa (EMCCA). To do this, a modified and adapted gravity model isconstructed and tested by the GMM method. The main result shows that natural resources are by far the most significantdeterminant of FDI in the EMCCA. Market size (population and gross domestic product) may also play a role in attracting FDIin addition to natural resources and infrastructure. However, we find that economic openness remains to be perfect to attractforeign investors.

Abstract

The populations of 2,200 peoples who faced with flood disaster in Mahasarakham Province in 2011. The 401 peoples wereused as sample group. The questionnaire was used as instrument for data collection. LISREL was used for model verification.Considering on structural model confirmatory factors of Environmental Education Principle (EEP) and Community Strength(CoS) were able to explain the variation of endogenous factors of Inspiration for Flood Response (INS) to caused FloodResponse Behavior (FRB) with 87.00 percents. As a result, the equation 1 can be written as following.FRB = 0.99*INS + 0.069*EEP - 1.00*CoS ………………………(1)R2 = 0.75Equation (1) factors that had the most effect to Flood Response Behavior (FRB) was Inspiration for Flood Response (INS) andsubsequences were Environmental Education Principle (EEP) and Community Strength (CoS), these were able to explainedthe variation of Flood Response Behavior (FRB) with 75.00 percents. Moreover, confirmatory factors of EnvironmentalEducation Principle (EEP) and Community Strength (CoS) were able to explain the variation of confirmatory factors ofInspiration for Flood Response (INS) with 93.00 percents. Therefore, the equation can be written as following equation 2.INS = 1.91*CoS - 0.35*EEP ……………………..………..……(2)R2 = 0.93

Abstract

This research analyses empirically the determinants of export trade in Cameroon from 1970 to 2008. We use the two StageLeast Square to show that exchange rate, trade openness and export lag one period are the main determinants of export inCameroon. This result, although common in most Developing Countries are in contradiction with former studies, mostlybecause the foreign direct Investment was found to be not significant in determining the export in this Country.

Abstract

Bilingual signs are becoming a regular feature of our increasingly globalized and inter-connected world. Oneproblem many bilingual signs suffer from is their having different linguistic errors of varying degrees of seriousness.This study was carried out to investigate different linguistic errors, including grammatical, lexical and spelling, errorsfeaturing in a sample of bilingual signs in Iran. To this end, a number of Farsi-English road, street and shop signswere randomly selected and photographed by the researcher. The pictorial data were then subjected to erroridentificationand error-analysis procedures. Findings suggest that most errors in bilingual Farsi-English signs arelexical ones, though grammatical and other errors also have fairly high frequencies of occurrence in them.

Abstract

Seventy-five years after his death, a question remains as to whether Frederick Taylor’s scientifictheories of management have made a significant contribution to Public Administration. Taylor’stheories focused mainly on increasing productivity in industrial manufacturing environments. Theprimary concern was for a pragmatic approach to efficiency where planning and standardisationaimed to optimise the human element in production. The article examines how practitioners of PublicAdministration have adopted and implemented Taylor’s theories. Evidence was found in the work ofMorris Cooke, a Taylor disciple who focused on public sector oriented approaches to management andpolitical economy. Taylorism was apparent in the public sector in the years after World War II, aturning point and period when Taylorist theories were humanised. The aim of the article then is toexamine how Public Administration has drawn from the field of industrial psychology, towardsimproving operations in public organisations. The key question is: to what extent has industrialscientific management principles been adopted in the discipline of Public Administration? In light ofpoor service delivery in South Africa, it is a relevant question that has implications for improvingoperational efficiency. A historical literature review was undertaken to determine the influence ofTaylor’s scientific management theories on Public Administration. The findings drawn from this reviewand analysis will serve to inform the need for more orderly scientific approaches to service delivery.

Abstract

In democratic systems, public participation is understood to be complementary torepresentative democracy whereby regular parliamentary elections are held. The electedrepresentatives are expected to engage the public in decision-making processes to enhancetransparency and trust. Representative democracy additionally calls for the establishmentof public participation platforms for engaging the citizenry in all public affairs. Moreover,the rationale for public participation advocates for the public to actively participate in thedevelopment of plans at the formative stage, rather than after officials have committed toparticular choices. A self administered questionnaire survey was conducted to assess theperceptions of the Members of the Provincial Legislature, Parliamentary ConstituencyOfficers and administrative staff on how public participation has been institutionalized inthe Gauteng Provincial Legislature. The results of the survey show that the GautengProvincial Legislature is not adequately engaging its people in decision-making processesas per the constitutional mandate as provided for in the Constitution of the Republic ofSouth Africa, 1996. The research supports the notion that a direct democracy is not feasiblein modern nations, but it is important to have a model of democracy that will provide thebest possible degree of direct popular public participation.

Abstract

The Local Government sphere in South Africa faces several cogent developmentalchallenges. Several interventions have been introduced to confront these challenges, whichinclude poverty, unemployment and skills shortage, with partial success. In this article, aconceptual framework is proposed for small, medium and micro enterprises (SMMEs) inSouth Africa. The literature review includes an analysis of documents issued by fourmunicipalities as well by the former national Department of Provincial and LocalGovernment. In this regard, an explanation of the concept of SMMEs is provided so as tocontextualise the study. Apart from the lack of funding, SMMEs appear to suffer from a lackof information, efficient production technologies, and the inadequate use of managementand control systems. To further contextualise this study, the debate on local economicdevelopment (LED) in the South African local government sphere is presented to highlightthe current challenges. Common characteristics of LED and SMMEs are also enunciated soas to establish the nexus. Finally, drawing from the above context and discussions, aconceptual framework is articulated and presented, which is intended to assistmunicipalities to ensure that viable SMME strategies are developed.
