Abstract

It is a crucial issue alongside other important topics to the academic level and also for the students who are interested in thisregard. After the Second World War there were some writers who possessed some characteristics that we may categorize onlyto that period. One of these writers is the famous American one Joseph Heller. There are many books about the war butHeller’s masterpiece “Catch-22” is uncomparable to none of them. Heller is a satirical novelist, a short story writer and aplaywright.(a) The features that led to “Black Humor” .The humor that Heller makes use of is obviously a human selfishness invain, this is very well represented in almost all the characters of this novel. The humor is dressed up in these characters toexplain the absurdity even when they think that they are being moral and fair. (b)Humor as a stylistic choice. Joseph Heller isinterested in a non-chronological narration and has been focused in a repetitive style approach. Heller was not alone in the warnovels there many other such as Kurt Vonnegut ,or Thomas Pynchon etc

Abstract

The present study was aimed to analyze the impact of age and management experience on occupational stress of academicmanagers in Higher Education Institutions of Pakistan. Qualitative and quantitative approaches have been used to explore theimpact of age and management experience of occupational stress by using a sample of 120 academic managers of publicsector institutions of higher education located in Punjab, Pakistan. In order to select representative sample from the population,simple random sampling technique was used .Data were collected through registered mail and personal visits to the offices ofprincipals. Total sample size was 120.For data analysis; both descriptive and inferential statistics were used. Researchinstrument Occupational Stress Inventory–revised (OSI-R) was used to collect data. For data analysis Pearson Correlation andANOVA were applied. Data analysis revealed that significant negative relationship was found in responses of academicmanagers regarding impact of age and management experience on occupational stress. Findings also suggest that there is aconnection between age, management experience and the way stress is perceived.

Abstract

Gender differences in science have received serious attention in science education research for the last two decades. Boysand girls have been compared on various variables such as achievement, attitude, motivation, interest, and performancebehaviors. Moreover, the differences have been linked with unequal representation of men and women in science andtechnology – related careers indicating levels of contributions of men and women to national development. Therefore, thispaper contends that it is difficult to address the issue of national development particularly in science and technology withoutrecourse to the gender factor. Specifically, the 1995 Commonwealth Plan of Action on gender and development, indicates that“the Commonwealth shall work towards a world in which women and men have equal rights and opportunities in all stages oftheir lives to express their creativity in all fields of human endeavour and in which women are respected and valued as equaland able partners in establishing values of social justice”. This paper poses and answers these questions: (a) What is thepattern of gender differences in science achievement internationally and in the Caribbean? (b) What are the possibleexplanations for gender differences in science achievement internationally and in the Caribbean? (c) What are the effects ofgender differentials in science on national development? (d) What are the possible intervention strategies towards genderbalance in science achievement? This paper presents answers to these questions using reports of meta-analysis of scienceeducation research and goes ahead to offer suggestions for action as to how gender gaps can be bridged in the Caribbean inorder to ensure contributions of both men and women to regional scientific and technological development.

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.
