Academic writing is not just about presenting a set of ideas, but through the act of writing, the authors position themselves as individuals having particular identities which mostly reflect the dominant sociocultural values and practices of the discourse communities in which they are living and performing. The present study, using a mixed method approach, attempted to explore the evidences of voice and subject positioning, as reflections of authorial identity, in the argumentative writings of 41 advanced Iranian EFL learners. At first, the relationship between voice intensity and overall writing quality of the participants was assessed and the results indicated a positive relationship between the constructs. The multiple regression analysis conducted also revealed that assertiveness, as one of the main subcomponents of voice in writing, had the highest level of contribution in accounting for the writing competence of the learners. Afterwards, some representative instances of subject-positioning (i.e., ideational, interpersonal and textual) in the written texts were identified and discussed based on the ideological context of the study since it is believed that authorial identity and voice can vividly reflect the overall ideology of the specific discourse community in which they are constructed. Finally, it was suggested that raising the awareness of learners and even instructing them about the significance of authorial identity, voice and subject-positioning in writing can assist them in constructing more authentic texts in terms of idea presentation, consideration of readers and specific textual and linguistic features used.

Digital identity presentation via social network sites illustrate the extent individuals reveal or conceal aspects of their identities because of their socio-cultural context. This qualitative case study examined the Facebook presence of ten adult Iranian Facebook users living both inside and outside Iran. Findings revealed social and cultural constraints, conservatism and external and self-imposed boundaries enacted by participants via their Facebook avatars and manipulated online images. Participants used Persian, English and Arabic languages to represent different elements of their identities based on their socio-cultural opportunities, their needs for self-preservation and their maintenance of image and face.

We show that the Liechti-Strenner's example for the closed nonorientable surface in \cite{LiechtiStrenner18} minimizes the dilatation within the class of pseudo-Anosov homeomorphisms with an orientable invariant foliation and all but the first coefficient of the characteristic polynomial of the action induced on the first cohomology nonpositive. We also show that the Liechti-Strenner's example of orientation-reversing homeomorphism for the closed orientable surface in \cite{LiechtiStrenner18} minimizes the dilatation within the class of pseudo-Anosov homeomorphisms with an orientable invariant foliation and all but the first coefficient of the characteristic polynomial $p(x)$ of the action induced on the first cohomology nonpositive or all but the first coefficient of $p(x) (x \pm 1)^2$, $p(x) (x^2 \pm 1)$, or $p(x) (x^2 \pm x + 1)$ nonpositive.

The purpose of this study is to determine the effectiveness of instructional strategies administered by primary school Science and Social Sciences teachers based on the opinions of students, and to identify if there is any difference between teachers of the two courses in terms of the level that they carry out these activities. This study is descriptive in nature. 7th grade students at primary schools in Melikgazi, Kayseri, during the spring term of 2004-2005 formed the research universe of the study. There were 87 primary schools in Melikgazi when the study was conducted. Ten primary schools were identified by stratification method, and 7th grade students in one of the classes of each school were chosen randomly and assigned as the sample group of the study. There are totally 300 students (30 students from each school) in the sample. The findings of this study reveal that strategies in the instruction step of a lesson are not applied effectively. Most of the activities were found to be conducted occasionally in both groups. According to the results, teachers of Social Sciences were identified to be more productive and effective than those of Science course in the following areas: providing reinforcement and prompting, being understanding and affectionate, using course-related tools and instruments, and creating a classroom environment where students participate actively. Summary Lesson plan consists of three interwoven steps; preparation before the lesson, planning and administering the lesson, and follow-up activities. Effective teaching is based on a well-developed plan, a well-managed classroom, and an effective presentation. Making necessary preparations and planning before a lesson may contribute a lot to success of students. A teacher has to get prepared before the lesson and has to plan the presentation, instruction, and assessment activities of the lesson in order to maintain students' interest, to maintain participation, and to sustain students' motivation at a high level. Therefore, it is vital for teachers both to be informed about instructional strategies and to have related skills to carry out these strategies. Presentation, instruction, and assessment activities within a lesson plan display different characteristics and have distinct steps. Instructional strategies are more important in nature since this is the phase when teaching is administered and learning takes place. All the definitions, concepts, rules, formulae, and explanations are delivered to students during this step. The information flow in this phase is from simple to complex, from concrete to abstract, from known to unknown, and from immediate to far. Teachers should be aware of the stimuli that affect students' learning and should use them when needed. During the instruction step, teachers should create a setting that increases interaction among students, trains them on cooperation, and improve their self-confidence; should provide various sources of information; should encourage students to learn by discovering; and should make use of methods and instruments that assess students' performance. The purpose of this study is to determine the effectiveness of instructional strategies administered by primary school Science and Social Sciences teachers based on the opinions of students, and to identify if there is any difference between teachers of the two courses in terms of the level that they carry out these strategies. Since a survey/questionnaire is utilized for the above purpose, this study is descriptive in nature. Method Sample 7th grade students at primary schools in Melikgazi, Kayseri, during the spring term of 2004-2005 formed the research universe of the study. There were 87 primary schools in Melikgazi when the study was conducted. Ten primary schools were identified by stratification method, and 7th grade students in one of the classes of each school were chosen randomly and assigned as the sample group of the study. There are totally 300 students (30 students from each school) in the sample. Researchers visited all these schools and distributed the questionnaire forms personally. Then, students filled out the forms under the supervision of researchers. Instrument The first draft of the questionnaire used in this study was developed in accordance with the related literature. Afterwards, the draft version was analyzed by experts in educational sciences and teachers lecturing Science and Social Science in terms of its content validity, and all necessary corrections were completed. Then, the questionnaire form was applied to a group of students to see if the statements were clear or not. After all the revision efforts, the questionnaire including 21 items about both lessons was given its final form. Cronbach Alpha Reliability coefficient of the questionnaire was found to be 0.86. Findings and discussion The findings of this study reveal that strategies in the instruction step of a lesson are not applied effectively. Most of the strategies were found to be conducted occasionally in both groups. According to the results, teachers of Social Sciences were identified to be more productive and effective than those of Science course in the following areas: providing reinforcement and prompting, being understanding and affectionate, using course-related tools and instruments, and creating a classroom environment where students can participate actively. On the other hand, teachers of Science course were assessed as more able in encouraging whole-class participation. Teachers may make use of various teaching techniques and methods in the classroom providing that they are informed about instructional strategies that should be taken into consideration during both planning and administering steps of a lesson and about different instructional methods. So at certain intervals, teachers may get feedback from students regarding their own behaviors and may make necessary amendments accordingly. Teacher training institutions and programs may be improved in terms of equipment and service provided for students. Teachers might be guided to attend in-service training programs designed to compensate for their insufficiencies concerning preparation, administration, and assessment of a lesson, and to inform them about innovations in teaching.

Multimodal resources and digital multimedia technologies have been modifying and remodelling social practices in any field over the last decades. In business communication, histories of business, corporate vision and mission are today instantiated by the ‘About Us’ webpage, a sort of multimodal self-portrait or short autobiography created by the company itself. From a discursive perspective, this webpage typology has always been disregarded if compared with the crucial role played by the homepage that, according to the Usability guidelines, is to present the company, its business and market value. Only recently, web marketers have focused on the strategic function the undervalued ‘About Us’ page fulfils. It has revealed itself to be a goal-oriented sales page which focuses on highlighting the most relevant credentials of a company, its brand, and on making a strong impression on potential customers. Its aim is to remodel practices of Self presentation into practices of Self branding and this process takes place thanks to the co-deployment of different semiotic resources which, in turn, make use of different digital media technologies. This contribution will show how the specialized discourses of marketing and branding are translated, or rather transducted, into multimodal artefacts, the corporate ‘About Us’ pages, and how persuasive discursive strategies are embedded in a well-defined digital text pattern. Through the analysis of a small sample of corporate ‘About Us’ pages, we will demonstrate that these pages are the loci where business reputation and corporate identity can be constructed more effectively.

This thesis investigates the music-cultural identity and conservational dilemma of the hitherto un-researched music-culture of the Islanders (Urang Pulo) of the Banyak Archipelago in Aceh-Singkil Regency off the west coast of Aceh, Indonesia. The Islanders’ dominant concept of identity is coloured by their dominant sikambang music, dance and legend, history of cultural contact with west-coastal Sumatran Malay and offshore island area, Niasan and Simeulue immigration to the Islands, the cultural memory of their former court centre at Haloban, the Islanders’ peripheral contact with the Dutch colonial power, and their typically Malay kacokan tendency to combine selective elements of cultures with which they have been in sustained contact. The people’s traditional customs (adat istiadat) and Animist-Muslim worldview shine through their vocal and instrumental music, dances, and bardic story-telling genres at weddings, circumcisions and in daily routine. The thesis’ original contributions to the discipline of ethnomusicology primarily lie in the areas of music-cultural identity, identity and place, vocal quality, culture contact, musical symbols of pre-colonial Malay kingdoms, gender, emotional expression in performance, and music revitalisation theory in recent modernising times. To begin to solve the conservation dilemma, the whole west-coastal population of Sumatra needs to be mobilised to fight for the area’s economic development partly through revitalising their rich sikambang heritage. This is important not only to save the art forms from extinction and expose them to the world but also for the maintenance of the local people's sense of identity and self-confidence.

Typhoid fever, caused by Salmonella enterica serovar Typhi, is the most common cause of enteric fever, and presents classically with fever and other gastrointestinal symptoms. We report an interesting case of a 27-year-old Indian man who lives in a semiurban area of Haryana (northern India) and presented with a 3-day-long history of intermittent fever, chills, and rigor. He was misdiagnosed previously as having mumps fever in view of the clinical presentation, but later, with proper workup, it was found to be an atypical presentation of typhoid fever. He responded well to intravenous antibiotics and recovered completely from typhoid infection.

Background: As Australia becomes an increasingly culturally diverse society through migration, there is a need to better understand the health of migrant groups. While literature on migrant health in Australia exists, there are gaps in coverage. Research indicates that South Asians (SA) have higher rates of both cardiovascular disease (CVD) and type 2 diabetes (T2D) in comparison to host populations in other western countries. This also occurs at younger ages and with greater severity of CVD. However, there is a paucity of studies that compare and examine the presentation of T2D and/or CVD in SA Australian dwelling migrants with members of the host population and there are equally few studies that explore their experiences and perceptions of living with these diseases. Aim: The body of work presented in this dissertation aimed to address the patterns of CVD presentation amongst Anglo-Australians (AA) and Australian dwelling SAs and to examine and explore the perceptions and experiences of SAs and AAs living with T2D and/or CVD. Methods: This study was divided into two phases. Phase 1 was a retrospective hospital clinical case audit to determine patterns of CVD presentation. The study population included SA and AA patients hospitalised for ischaemic heart disease. Baseline characteristics, evidence of diabetes and other CVD risk factors were compared. Angiographic data were also compared to determine severity and these were assessed using a modified Gensini score. In phase 2, semi-structured indepth interviews were conducted with 57 participants (41 SAs and 16 AAs) with either T2D and/or CVD. Results: Phase 1 confirmed the SA pattern of CVD presentation in other western nations, i.e. high rates of cardiovascular disease at younger ages, with greater severity, higher rates of T2D and low BMI measurements (a conventional risk factor). Findings from phase 2 indicated key similarities and differences between the perceptions and experiences of the participants drawn from the two ethnic groups. These pertained to their engagement with health professionals and the health system, their self-management practices such as physical activity and dietary patterns, as well as the bidirectional effects of migration on their health related behaviours. Conclusions and future direction: The findings presented in this thesis have made an original contribution in an area where there is a strong need for an evidence base to inform health service delivery and public health action to alleviate the increasing burden of CVD and T2D among SAs. This group should be targeted for more aggressive screening for these diseases at younger ages with more intensive treatment strategies. Prevention and management strategies need to be individually and communally tailored as well as culturally appropriate. Health professionals should bear this in mind when providing clinical advice. Similarly, those responsible for the development and implementation of health promotion interventions for prevention and management of these diseases will need to consider culturally sensitive approaches.

Imported malaria is a frequent diagnosis in Portugal, and in the most severe clinical forms it may present a high mortality rate. We present seven cases of severe imported malaria, admitted to an intensive care unit between 2000 and 2010, with particular focus on risk factors, clinical presentation, treatment and results. All patients had a history of recent travel to African endemic areas for malaria. Plasmodium falciparum was the agent isolated in all cases. Most patients had an inadequate prophylaxis. High parasitaemia in non-immune patients and treatment delay were associated with more severe clinical presentation. All the cases were complicated by organ failure, and three patients needed organ support and in two exchange blood transfusions were performed. There was one single death that was associated with marked delay in the initiation of therapy. In these patients, early and aggressive treatment, with a organ support in a critical care setting, allowed a good outcome with low mortality and no significant sequelae, despite the severity of presentation.

The aim of this research is to know the factuality, the impartiality and the social impact of Harian Ambon Ekspres in reporting conflict in Maluku. This is a qualitative descriptive research that using a content analysis method in analyzing the whole conflict report content in Harian Ambon Ekspres in order to elaborate the journalistic rule that applied by Harian Ambon Ekspres institution relating to the social and politic stability in Ambon. The analysis units in this research are the conflict report that served in Harian Ambon Ekspres in early 2008 until February 2009 period with types of SARA (clan, religion, race and groups), socio-cultural and politic Conflict Report. The result of the research indicate that, according to the factuality most of the report that served suitable to the facts that happen, this is because of the existence of the official confirmation source from the in service government and security apparatus at the conflict area. Otherwise, according to the impartiality, the unbalance report service is dominant in Harian Ambon Ekspres journalistic practice, this is because of the un-existence of certain party confirmation as the conflict contestant and the cover both sides practice. Factual information presentation without journalistic ethic limitation and partial report presentation has a negative impact and it is nonsupport in creating social and politic stability in the community around the conflict area.

We repurpose existing RSA/ECC co-processors for (ideal) lattice-based cryptography by exploiting the availability of fast long integer multiplication. Such co-processors are deployed in smart cards in passports and identity cards, secured microcontrollers and hardware security modules (HSM). In particular, we demonstrate an implementation of a variant of the Module-LWE-based Kyber Key Encapsulation Mechanism (KEM) that is tailored for high performance on a commercially available smart card chip (SLE 78). To benefit from the RSA/ECC co-processor we use Kronecker substitution in combination with schoolbook and Karatsuba polynomial multiplication. Moreover, we speed-up symmetric operations in our Kyber variant using the AES co-processor to implement a PRNG and a SHA-256 co-processor to realise hash functions. This allows us to execute CCA-secure Kyber768 key generation in 79.6 ms, encapsulation in 102.4 ms and decapsulation in 132.7 ms.

In this paper, the linear invariance of evolutionary game dynamical systems is exploited to systematically realize the spatial partitioning of payoff matrix parameters on a two-dimensional regular lattice with the Neumann neighborhood and the deterministic imitation rule. It is shown that 264 evolutionary game dynamical systems are identified. Meanwhile, a homeomorphism group is set up to establish 132 topological conjugacy equivalence classes. Particularly, for the snowdrift game model, 28 partition regions of the payoff matrix parameters are determined, and the corresponding bifurcation diagram is illustrated. Additionally, some subsystems of the evolutionary snowdrift game dynamical systems are constructed utilizing the glider structures, and the topological conjugacy relationships between these subsystems and infinite product systems of finite-type subshifts are analyzed. Subsequently, their chaotic dynamics is investigated in detail, including properties such as topological mixing and topological entropy, which reflect the complexity and unpredictability of the underlying evolutionary behaviors. It is undeniable that the proposed analytical method can be used to characterize the evolutionary game dynamics on regular grids with symmetric neighborhood structures and deterministic updates, offering a systematic and coherent theoretical framework for analyzing evolutionary dynamics.

In this study, the prediction errors of various spatial interpolation methods used to model values at unmeasured locations was compared and the accuracy of these predictions was evaluated. The root mean square (RMS) was calculated by processing different parameters associated with spatial interpolation by using techniques such as inverse distance weighting, kriging, local polynomial interpolation and radial basis function to known elevation data of the east coastal area under the same condition. As a result, a circular model of simple kriging reached the smallest RMS value. Prediction map using the multiquadric method of a radial basis function was coincident with the spatial distribution obtained by constructing a triangulated irregular network of the study area through the raster mathematics. In addition, better interpolation results can be obtained by setting the optimal power value provided under the selected condition.

The Uniformization Theorem due to Koebe and Poincare implies that every compact Riemann surface of genus greater or equal to 2 can be endowed with a metric of constant curvature – 1. On the other hand, a compact Riemann surface is a complex algebraic curve and is therefore described by a polynomial equation with complex coefficients. The uniformization problem is then to link explicitly these two descriptions. In [BS05b], Peter Buser and Robert Silhol develop a new uniformization method for compact Riemann surfaces of genus two. Given such a surface S, the method describes a polynomial equation of an algebraic curve conformally equivalent to S. However, in this method appear a complex number τ BS and a function f BS which is holomorphic on the unit disk, both being characterized by some functional equations. This means that τ BS, f BS are given implicitly. P. Buser and R. Silhol then approximate them numerically by a complex number τ and a polynomial p using the approximation method developped in [BS05a]. In cases where the equation of the algebraic curve is known, they notice that these approximations are very good. In this thesis we prove a convergence theorem for the approximation method of P. Buser and R. Silhol, and we propose an adaptation of their method that allows to solve some of the numerical problems to which it is prone. Moreover, we generalize this uniformization method to hyperelliptic Riemann surfaces of genus greater than 2, and we give some examples of numerical uniformization in genus 3.
