Background: Individual differences in morphometric and somatoscopic observations of pinna of ear were studied to explore the potential of pinna of ear as a biometric tool.Methods: Morphometric and somatoscopic data of right ear of 350 Indian individuals (Age: 17-25 years) was collected. Measurements of pinna length, pinna width, pinna root, pinna projection, intertragic distance, ear lobe length, and ear lobe width were taken. Observations were done for presence or absence of Darwin tubercle, flat or rolled helix, and attached or free ear lobe. Probability statistics was extrapolated to assess the variations in ear pinna characters.Results: All measurements showed a wide range. There was statistically significant difference between male and female pinna measurements. The somatoscopic observations showed 82.9% individuals with presence of Darwin tubercle, 99.1% with rolled helix, and 65.4% with free ear lobes. On the basis of extrapolation of ten different morphometric and somatoscopic parameters, the statistics showed the probability of any two individuals having exactly same observations to be 0.0008%.Conclusions: The wide range of measurements in the present study suggested a high possibility of variations amongst the population. If all the parameters including both morphometric and somatoscopic, are taken into consideration, the pinna of ear of each individual is a very distinctive structure, which makes it a potential biometric identifier and with the use of proper technologies, it will be a widely used biometric tool in the future.

Teachers are being seen as the ultimate key to educational change and school management. Proposals made at the macro-level of educational policy depend for the effectiveness on the interpretation by teachers at the micro-level of pedagogic practice and on their abilities to understand and carry out these proposals. Furthermore, there are indications of a strong demand for qualified professionals to staff classrooms well in the future. Thus, it is reasonable to argue that the need for an effective provision to initiate, develop and sustain teachers through an appropriate process of education consequently should be among the highest priorities of educational policy. The motivation for the study stems from: a) the fact that the establishment of English language teaching in Primary Education has raised new teaching needs and teachers are required to respond to a wide range of demands. However, they have not received the adequate pre-service education and in-service training to meet the pedagogical and teaching demands in the Primary Education context, b) the absence of empirical researches dealing with the specific issue in Greece. The present study, which is limited to Greek primary EFL teachers, represents a descriptive research study in its method and is policy-oriented in its purpose. We tried to identify teachers’ INSET needs, to investigate the nature of the discrepancy between the provision of in-service training and the needs and wants of the targets, to pursue the investigation until we came up with an alternative INSET model framework. The objectives were the following: a) to reveal and shed light on the current INSET provision for EFL teachers in Greece, b) to identify the EFL teachers’ and advisors’ viewpoints concerning INSET organizing and planning, c) to identify the future EFL teachers’ INSET needs as perceived by the teachers themselves and the EFL advisors, d) to suggest a framework of a model for INSET based on the target needs of the EFL teachers, the current status of INSET provision for the EFL teachers and the related literature. More precisely, chapters one, two, three, four, five and six aim to provide a theoretical basis for this study, which, together with the field of study results, will help in the formulation of some new plans. The first chapter concentrates on definition of INSET, the purpose and importance of INSET, the effectiveness of INSET. The second and third chapters review the literature related to the theories and practices of INSET in order to highlight characteristics of effective INSET at the level of teacher behaviour change and improvement of teaching skills. The fourth chapter gives background information concerning the teaching of English language in Greek Primary schools. The fifth chapter describes the state teachers INSET in Greece with specific reference to the education and training of teachers of English as a foreign language and their academic profile. It provides a brief analysis of the policy of teacher preparation in order to highlight the strengths and weaknesses of the present system. The sixth chapter sets out models and forms of INSET. It concerns the content of the INSET programmes and it explores - explains the activities and procedures through which the content of INSET can be transmitted. The seventh chapter identifies and states the problem and presents the significance and objectives of the study. It outlines the type of research and the area of investigation, explains and justifies the methods and the instruments (questionnaires and interviews) of data collection and describes and defines the population and sample. It rationalizes the procedures used in collecting the data and explains the techniques used to analyze and interpret the findings of the study. In the eighth chapter, we present the results of the study, which clarify the nature of the discrepancy between the provision of INSET and the needs and wants of the targets. The findings of the study, which point to an absence of any significant difference in the perceptions of the two groups-teachers and advisors-, indicate the need for a new policy and plans to be established, commencing with the recommended ways of assessing teachers’ INSET needs, and extending to evaluation and feedback into the INSET system. In the ninth chapter INSET recommendations for an improved model for EFL teachers are set out in terms of a discussion of findings. The findings of the present study revealed that there was a gap between the current INSET provided by the ministry of Education and the perceived needs. An interim framework of INSET model, called the Participatory-Collaborative INSET model was designed to fill in the gap.

The study entitled ‘Career aptitude assessment of the undergraduate agricultural students in Kerala Agricultural University’ was undertaken with 120 undergraduate agricultural students of the three colleges under Kerala Agricultural University (KAU) during 2018-19. Ex post facto research design was used for conducting the study and  sample of the study comprised of 120 third year and final year students i.e., 60 students from COA, Vellayani, 35 students from COH, Vellanikkara and 25 students from COAP, Padannakkad were selected based on proportionate random sampling method.  The results of the study revealed that majority of the undergraduate agricultural students had medium to high mechanical reasoning, language usage capability and numerical ability. Almost 71.68 per cent of the undergraduate agricultural students had high verbal reasoning ability and majority (78%) of the students had medium to low word knowledge. It was also observed that majority (95%) of the undergraduate agricultural students had medium to high career aptitude. These results indicated that undergraduate agriculture students have the desired skills to succeed in plethora of jobs i.e., from low profile jobs to high profile administrative and management jobs. Further, Man – Whitney test had been undertaken to test the significant difference between career aptitude of male and female students. The results revealed that regardless of their gender the career aptitude of the male and female students remained same. From this study it is evident that undergraduate students of KAU are suitable for wide range of occupations / vocations / careers from farming to agribusiness, from clerical job to the high profile administrative jobs, from farmer to the management professional, from private jobs to the government job, from extension agent to the agricultural scientist and so on.

The purpose of this paper was to examine the relations between the ability to separate simultaneous sentences spoken by talkers of different gender and the ability to separate pitch patterns in a sequential stream segregation task. Simultaneous sentence pairs consisting of 1 sentence spoken by a male talker and 1 sentence spoken by a female talker were presented to 11 listeners with sensorineural hearing loss. Listeners were asked to repeat both sentences and were scored on the number of words repeated correctly. Separate scores were obtained for the male and female sentences. Sequential stream segregation was then measured using series of tones consisting of a fixed frequency (A) and a varying frequency tone (B). Tone series were presented in an ABA_ABA_... pattern starting at a varying frequency either below (ascending pattern) or above (descending pattern) the frequency of the fixed 1000 Hz tone. Fusion thresholds, defined as the frequency separation at which listeners could no longer perceptually separate the tones A and B, were obtained for both ascending and descending patterns. There was no significant difference between ascending and descending fusion thresholds based on the group data, but substantial individual differences were observed. Speech recognition scores for the male talker were strongly related to ascending fusion thresholds, but not descending thresholds. In contrast, speech recognition scores for the female talker were strongly related to the descending thresholds, but not the ascending thresholds. For both the male and female talkers, better recognition scores were associated with lower (nearer to normal) fusion thresholds. Results suggest that the importance of streaming in the perceptual separation of talkers may depend on the nature of the information provided by the changing pitch stream.

Background. Although high expressed emotion (EE) has been found to be an important predictor of poor prognosis in a wide range of conditions such as schizophrenia, anorexia and depression no complete explanation exists for individual differences in EE responses The aim of this paper is to investigate the role of intimacy in determining the level of EE in carers of people with dementia.Methods. Ninety-nine carers of people with dementia who presented to Old Age Psychiatry Services in South and Central Manchester completed questionnaires to ascertain past and current levels of intimacy. Camberwell Family Interviews (CFIs) were carried out to ascertain levels of EE.Results. Current intimacy was found to be strongly related to EE such that low current intimacy was associated with high EE and there was a significant difference between high and low intimacy groups on measures of criticism and hostility, though not warmth.Conclusions. The association found between intimacy and EE indicates that high EE may be a characteristic of low intimacy relationships between the carer and the cared-for-person. Since the assessment of EE is time intensive, perhaps a measure of intimacy will provide a short-hand screen for identifying critical and hostile caring environments.

The study explored the developed social skills between male and female students at the elementary level. A total of 550 Students were selected using multi-stage cluster sampling in the district of Lahore. Explored social skills included accepting criticism, showing respect, solving problems, accepting rights & responsibilities and tolerance of individual differences. A scale consisting of sixty-nine items was developed and standardized through factor analysis. The instrument was checked and ensured for reliability measures using Cronbach's Alpha (r = .75, p < .05). Five factors were identified through exploratory factor analysis using the principal component matrix measuring students' level of social skills at the elementary level. Results of the study showed statistically significant difference based on the gender of the student for the subscale "accepting criticism", revealing male students being more developed in social skill compared to their female counterparts, whereas female students were found more mature for the social skill requiring tolerance of individual differences as compared to male students. The study has implications for future researchers and school authorities.

Purpose This study explored group experiences and individual differences in the behaviors, thoughts, and feelings perceived by adults who stutter. Respondents' goals when speaking and prior participation in self-help/support groups were used to predict individual differences in reported behaviors, thoughts, and feelings. Method In this study, 502 adults who stutter completed a survey examining their behaviors, thoughts, and feelings in and around moments of stuttering. Data were analyzed to determine distributions of group and individual experiences. Results Speakers reported experiencing a wide range of both overt behaviors (e.g., repetitions) and covert behaviors (e.g., remaining silent, choosing not to speak). Having the goal of not stuttering when speaking was significantly associated with more covert behaviors and more negative cognitive and affective states, whereas a history of self-help/support group participation was significantly associated with a decreased probability of these behaviors and states. Conclusion Data from this survey suggest that participating in self-help/support groups and having a goal of communicating freely (as opposed to trying not to stutter) are associated with less negative life outcomes due to stuttering. Results further indicate that the behaviors, thoughts, and experiences most commonly reported by speakers may not be those that are most readily observed by listeners.

In the Macedonian literary language the analytic da-construction used in an independent clause has a wide range of possible modal meanings, the most common of which are imperative and optative. The present article offers a detailed analysis of the semantics and functions of the Macedonian optative da-construction based on fiction and journalistic texts. The first part of the article deals with the specificities of the optative as a category which primarily considers the subject of a wish. In accordance with the semantic characteristics of this category, optative constructions are used in those discourse text types where the speakers are explicitly designated (the most natural context for the optative is the dialogue). The analysis of the Macedonian material includes instances of atypical usage of the optative da-construction, in which the wish of the subject is not apparent and thereby produces new emotional tonalities perceptible to the reader of a fiction/journalistic text. The study describes Macedonian constructions involving two different verb forms: 1) present tense form (da + praes) and 2) imperfective form (da + impf). These constructions formally designate the hypothetical and counterfactual status of the optative situation, respectively. Thus, the examples in the analysis are ordered according to two types of constructions, which reflect the speaker’s view on the probability of the realisation of his/her wish. Unrealistic wishes can be communicated through the present da-construction, while the imperfective construction denotes situations in which the wish can be realised in the future. The second part of the article is devoted to performative optative da-constructions, which express formulas of speech etiquette, wishes and curses. The analysis demonstrates that these constructions lose their magical functions, when used outside of the ritual context, and begin to function as interjections.
