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

The rise of the expressive theory of authorship in the literary movement that we call Romanticism radicalised the ideasthat the artist is a genius and the work of art is autonomous from the actual reality as it results from an imaginary universe whichis specific to a certain artist. Romantic emphasis on subjective experience and the disinterestedness of the creative act was alsoan aspect of its rejection of the principles of Enlightenment and Neoclassicism. Moreover, although time and place specific andemerging in connection to French Revolution and Industrial Revolution, the exponents of Romanticism were escapist rather thanrebellious as to attempt the improvement of the social conditions. These are some of the reasons that have made critics regardRomanticism as an artistic not social movement and be reluctant to speak about a Romantic ideology in Marxist termsconcerning the socio-historical position of literature, especially when referring to the great Romantic literary criticism expressedin Wordsworth’s Preface to Lyrical Ballads, Coleridge’s Biographia Literaria, and Shelley’s Defence of Poetry. These textsrepresent the main concern of the present study, in relation to which the aim of the study is twofold: first, to discern among theideas and principles regarding the origin of poetry, its subject-matter and language, the role of the poet, and poetic imagination,and, second, to present the ways in which these ideas are materialised or not in literary practice, namely in Wordsworth’s TinternAbbey and Shelley’s To a Skylark.

Abstract

This study aims to investigate the claims of Aspect Hypothesis which holds that in the past tense, perfective verbsprecede imperfective verbs, having a different pattern of acquisition based on their lexical aspect, i.e., learners initiate usingperfective past marks from the prototypical verbs which contain the achievement and accomplishment lexical aspects, while theystart using imperfective past marks from the verbs whose lexical aspects are stative and activity. In this study, ten Iranian (fromMashhad) Farsi speaking learners of English were given a film to watch and retell the story in impersonal narrative in past tense.The verbs which they applied were classified into 4 lexical aspect categories with different semantic features like telicity,durativity, and dynamicity; these categories include: state, achievement, accomplishment and activity. The results suggest thatatelic verbs like state and activity verbs were easier for the students to produce in past perfect and the atelic durative verbsactivities-were produced with higher accuracy in past imperfective.

Abstract

Written texts of any kind embody some interactions between writers and their potential readers. This study focused onacademic writing to find about linguistic features used by writers to create such interactions. Following Hyland’s (2005) model ofinteraction in which stance and engagement are introduced as two discoursal features having an effective role in constructingwriter-reader interactions, this study aimed at investigating the ways in which English and Persian academics express theirposition to discover the strategies used to bring readers to their writing. To this end, 120 English and Persian research articles intwo disciplines of Chemistry and Sociology were analyzed for the purposes of cross-linguistic and cross-disciplinary comparison.The results demonstrated that the writers of both disciplines, especially the sociologists, considered the expression of stanceand engagement markers in their writing important. However, in sociology articles there was a greater effort to interact withreaders. Further, in Persian there seemed to be more cases of readers’ involvement.

Abstract

This paper discusses the translation of spoken words and phrases from English to Persian. Verbal communication isone of the aspects of culture, translation of which really matters in intercultural studies. So, in order to evaluate the efficacy ofthis transfer from source language to target language, we take Newmark’s communicative and semantic approach. To conductthis research, 10 MA students of translation studies are picked and asked to translate 25 sentences each of which containsspoken words or phrases. Based on Newmark, sentences should be rendered into target language communicatively andparticipants rendered only 31% of the items communicatively.

Abstract

This paper reports a study which aimed at exploring if there is any difference between the evaluation of EFL expertreaders and computer-based evaluation of English text difficulty. 43 participants including university EFL instructors andgraduate students read 10 different English passages and completed a Likert-type scale on their perception of the differentcomponents of text difficulty. On the other hand, the same 10 English texts were fed into Word Program and Flesch Readabilityindex of the texts were calculated. Then comparisons were made to see if readers' evaluation of texts were the same or differentfrom the calculated ones. Results of the study revealed significant differences between participants' evaluation of text difficultyand the Flesch Readability index of the texts. Findings also indicated that there was no significant difference between EFLinstructors and graduate students’ evaluation of the text difficulty. The findings of the study imply that while readability formulasare valuable measures for evaluating level of text difficulty, they should be used cautiously. Further research seems necessaryto check the validity of the readability formulas and the findings of the present study.

Abstract

The work draws attention on the treatment of educational with pluralism, evaluating it firstly as a solution to theAlbanian problems, analyzing educational issue connected with pluralism, making evident the Neo-Albanian views as questionsand ancient responses, as well as the state and its role on the development of pluralist institutions. Generally defined, the termpluralism states institutional forms for political power (force) distribution. In order to analyze the mentioned phenomenon, itmeans to examine the power or the distributed authority in society. Very often the term pluralism is used to signify any situationwhere there are no political, ideological, cultural and ethnic ruling groups. We mean that a certain situation is characterized bythe competition existing between elites or interested groups and the pluralist society allow this competition to be freelydeveloped. In the Albanian development circumstances of the 1930s, Neo-Albanians chose the pluralism of opinions, whichwere introduced in that time publications, especially in the “Albanian Attempt” magazine. We could conclude that the societies,which have a stable economic development, have developed the values and the appropriate structures connected withindustrialization, such as the efficiency, rationalism, re-investments and benefit; all these create the basis for the increasing rateof the integration of social groups on the basis of pluralism as a political solution. Otherwise, the Albanian society of the 21stcentury has not secured yet these stable economic developments, the values and structures connected with it and also becauseof the fragility are the democratic system and political pluralism.

Abstract

Since the Middle Age, when we have the first sources about the presence of the Gypsy community in Romania, theRoma population occupied a marginality place. The slavery, which they were subjects to since the XIV and XV centuries in theprincipalities of Wallachia and Moldavia, determined, as direct consequence, the placement of Roma in an inferior social positionand discrimination by the attitude of the Romanian population. This former condition of inferiority is necessary to understand themotivations that have determined such a little attention to the Roma and to the respect for its rights and its culturalcharacteristics. This is especially true by the end of the WW I, when Romania became a big country with a large territory andmany populations to rule. Since this time the Roma will suffer the politics of homogenization to the majority population andconsequent loss of cultural characteristics. Nevertheless during the interwar age there were attempts to preservations of identitycarried by some associations defending the rights of Roma .But these associations were suppressed in 1938, by theauthoritarian resolution of Carol II and then, in 1940, when Antonescu established the military dictatorship, any identity rights toRoma were denied: anyone who refused the homogenization was deported to Transnistria. Afterwards, in communist age, until1989, Roma were considered only as Romanian people, and therefore forced to live as the majority population. However theattitudes of discriminations against them did not stop, thus the Roma were not able to rise socially. In Romania today asignificant part of the Roma still lies in poverty, unemployment and illiteracy condition and it’s still considered the scum ofsociety. Trough the study of the history of Roma, we can understand the reasons of their diversity and the difficult integration inEuropean societies.

Abstract

Aim: the aim of the present study was to assess the validity of self-reported weight and height among Cypriotadolescents. Method: Adolescents’ weight and height was measured during school. Students completed the questionnairesEAT-26 and EDI-3. Results: self-reported and measured weight and height are highly correlated. Boys underreport their weightby 0.28 kg and over report their height by 0.84 cm; girls underreport their weight by 0.91 kg and over report their height by 1.52cm. 8% of overweight adolescents would have been neglected if self-report measures were relied upon. Overweight adolescentsmake greater self-report errors in BMI in comparison to their normal/ underweight counterparts. Adolescents who overestimatedtheir weight by 5% had lower scores on Drive for thinness scales and Body dissatisfaction scales. Conclusion: relying on selfreportestimates of height and weight can lead to erroneous conclusions of prevalence estimates of overweight and obesityamong Cypriot adolescents and must be used with caution.

Abstract

This study examined the impact of heterogeneity of effect size on the sample size of some validity studies. Thirty (30)empirical studies were selected on the basis of empirical status and relevance; their results both quantitative and qualitativewere recorded, coded and analyzed. The findings revealed that the differences in the results of the 30 selected empiricalstudies were a function of the sample size on which the studies were based. Mean Fisher ( Zr =0.393 , WZr=0.42347).Characteristics peculiar to each study did not affect the result of the study. Weighted Mean Fisher by sample size ( WZr)=0.398 with associated r=0.375) was an equivalent of the Mean Fisher. The results of the empirical studies were found to besignificantly different in terms of their effect sizes (÷2=1444.97 p ). The heterogeneity of the effect size was a resultof the heterogeneity of the sample size. The Weighted Mean Fisher was bigger than the Mean Fisher (WZr=0.489 ,Zr=0.393).The difference in the result was a function of differences in the sample size and not as a result of the study characteristicspeculiar to each study.
