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

This paper investigates socio-pragmatic transfer of speech acts from Persian language into English language. The researchercompares the data gathered from Persian speakers of English and American native English in five different service situations. Persianspeakers of English have different semantic interpretations from native American speakers, they conform to different sociolinguisticnorms. So when Persian speakers want to speak English they consider their own cultural and social norms and transfer them in toEnglish. Misunderstanding and break downs in conversations are due to this socio-pragmatic transfer. Adhering to different speakingrules and models of accepted behavior can cause different cultural perceptions about the L2 speakers, some of which are not trueperceptions of course. So we should be careful about false cultural perceptions naming stereotypes without having knowledge about L2speakers' cultural and social backgrounds.

Abstract

Numbers are widely used to form such metaphorical idioms as ‘at sixes and sevens’, ‘to be on cloud nine’ and ‘three sheets tothe wind’. A question arises as to how these number-related expressions acquire their metaphorical significance. Following Lakoff andJohnson (1980) and in the light of Conceptual Metaphor Theory, the present study investigates the relationship between language andculture in the construction of idiomatic expressions of number in English and Persian. The working hypothesis in the present study is thatalthough numbers have similar denotations across cultures, idiomatic expressions of number may represent culture-specific concepts.

Abstract

In the context of the largest crisis that capitalism has ever faced the discussion on social class and class consciousnessseems more relevant than ever. The Greek crisis strikes as an ideal opportunity to start this debate. The phenomenal rise of the middleclass in Greece over the last four decades has shaped a very problematic framework for a deep and rational analysis of social classes incontemporary Greek society. The policy that had enabled public servants and small businessmen to have access to social goods - thatuntil a few years ago was exclusive privilege of the upper class – has changed the dominant model of interpretation of social stratificationand hierarchy in modern Greek society. This study by using a mixed questionnaire (Likert scale and Content Analysis of the written texts)investigates the class stereotypes and the class consciousness of the Greek youth, while trying to clarify the facts of class stratification inthe country in the midst of an unprecedented economic, social and political crisis.

Abstract

The demands on supervisors both in and out of educational settings introduced by the recent learner-based innovations andcombined with increased work load have led many to question the levels of job satisfaction, occupational stress and burnout amongsupervisors. The goal of this article was to explore the levels of occupational stress, burnout and job satisfaction among supervisors inNorth Cyprus. The target population of this study was all supervisors working for the Ministry of Education, Youth and Sports in NorthCyprus. All 34 supervisors were included in the study. Data were collected through (1) Occupational Environment Scale (Osipow &amp;Spokane,1983), (2) the Maslach Burnout Inventory (Maslach &amp; Jackson, 1981b) and (3) the Minnesota Work Satisfaction Questionnaire(Weis et al.,1967). The level of job satisfaction of supervisors was found to be high, whereas levels of their occupational stress werefound to be moderate. The levels of emotional burnout and personal accomplishment were also found to be moderate but the level ofdepersonalization was found to be low among the supervisors.

Abstract

This study explored whether applying cooperative learning approach brings about significant improvements in Englishlanguage learners' speaking proficiency. 40 male and female students enrolled in a speaking course at IELTS Center institute inMashhad, Iran, were assigned randomly to two control and experimental groups. The administration of an oral interview showed that twogroups were homogeneous in terms of their oral proficiency at the entry level. While both groups received instructions in speaking threesessions per week for one month, CL activities were employed only in the experimental group. The performance of the experimentalgroup on oral interview (posttest) held at the end of the course showed that the mean score of this group was significantly higher thanthe control group. Hence, CL approach can effectively be implemented to improve the learners' speaking proficiency.

Abstract

There is a growing need to effectively address the sexual and reproductive health needs of adolescents in Nigeria. Researchshows a pattern of adolescent sexual behavior indicating early sexual debut and a prevalence of premarital sex. The traditional lack ofinterest in discussing sexuality at home, schools and churches creates a problem in teacher-student/ parent-child communication andthis has affected sexuality and sexuality education adversely overcoming communication barriers to sexuality education is critical to thewell-being of millions of adolescent in Nigeria today since communication barriers complicate the delivery of sexuality education both athome, churches and in schools. This paper therefore examines the dearth and ease in effectively communicating the idea of sexualitythrough the family, church and school which play major roles in socialization and ultimately, the education process. The paper concludesby discussing the social, health and educational implications of sexuality education in Nigeria.
