Communicator Style as a Predictor of Cyberbullying in a Hybrid Learning Environment
zcanzgür Dursun,Yavuz Akbulut
Turkish Online Journal of Qualitative Inquiry , 2012,
Abstract: This study aimed to describe the characteristics of undergraduate students in a hybrid learning environment with regard to their communicator styles and cyberbullying behaviors. Moreover, relationships between cyberbullying victimization and learners’ perceived communicator styles were investigated. Cyberbullying victimization was measured through a recently developed 28-item scale with a single-factor structure, whereas the communicator styles were measured through Norton’s (1983) scale which was recently validated in Turkey. Participants were a total of 59 undergraduate Turkish students enrolled in an effective communication course in 2010 spring and fall semesters. Face-to-face instruction was supported through web 2.0 tools where learners’ hid their real identities through nicknames. Participants used personal blogs in addition to the official online platform of the course. Their posts on these platforms were used as the source of the qualitative data. Descriptive analyses were followed by the investigation of qualitative and quantitative interrelationships between the cyberbullying variable and the components of the communicator style measure. Correlations among victimization and communicator style variables were not significant. However, qualitative analysis revealed that cyberbullying instances varied with regard to discussion topics, nature of the discussions and communicator styles. Example patterns from the log files were presented accompanied with suggestions for further implementations.

Abstract: Introduction: Leprechaunism is a rare autosomal recessive disorder caused by mutations in the insulin receptor gene. In this report; we present a 75 days old infant with leprecahunism treated by high dose insulin glargine.Case Report: Yetmi day old girl was diagnosed as leprechaunism because of the hyperglycemia, ketoacidosis and dysmorphic appearance. Huge cysts with multiple septa were determined in her ovaries. High dose insulin glargine were adjusted to achieve target blood glucose regulation. Huge ovarian cysts resolved by this treatment.Conclusion: Leprechaunism is characterized by intra-uterine and postnatal growth restriction, lipo-atrophy, characteristic facial features, severe acanthosis nigricans, abnormal glucose homeostasis, clitoromegaly and hirsutism. It is usually fatal within the 1st year of life because of diabetic ketoacidosis or recurrent infections. (Journal of Current Pediatrics 2010; 8: 119-22)

Abstract: Penile foreign body injection is an uncommon entity produced by penile paraffin, mineral oil, and vaseline injections for the purpose of penile enlargement. Generally, penile subcutaneous and glandular injections for penile augmentation are performed by a nonmedical person, under unacceptable conditions. It will be an aim to share our experiences about penile vaseline injection. 1. Introduction Bigger sexual organ was the symbol of power in many cultures. Injection of foreign substances into penis in order to make the sexual organ appears bigger is reported especially in Asian and Eastern European countries [1]. Paraffin, Vaseline and mineral oil, and so forth are generally used as foreign substances [2]. In some of the Asian countries, placing small chagan balls under penis skin in order to improve sexual pleasure of the partner can be seen especially among men with lower socioeconomic level. Years after the injection, granulomatous skin reaction referred to as vaselinome or paraffinom may occur and adverse effects such as infection, ulceration, fistula, local migration, and cavernous invasion may also occur [3]. In diagnosing foreign substance reaction, venereal diseases and squamous-cell carcinoma should be noted [4]. Injection of foreign substances may be a predisposing factor for Fournier gangrene, even very rare [5]. The most important step during the cure is to completely dissect and pull out the foreign substance [6]. Then, if primary enclosure is possible, it should be done or it should be repaired by scrotal flap or full layer skin grafts. Antibiotic therapy is only important in controlling secondary infections. Some authors stated that formation of sclerosant lipogranuloma can be cured best by corticosteroids [7]. 2. Case Presentation A 42-year-old male patient had applied to our clinic with a claim of pain in his penis. It is understood according to patient’s history that he had a multiple heated Vaseline injection done under penis skin one month ago for augmenting his penis. In patient’s physical examination, it was palpated that there were soft-formed fixed and widespread mass lesions under penis skin. No deformation was found on penis skin surface (Figure 1). Patient stated that he had normal erection but he felt pain during sexual relation. In preoperative examinations done on the patient, no biochemical or hematological disorder was detected.

Abstract: Core Functional Categories are defined to be v0, T0, C0. They differ in that T0 is not treated as a phase head, while C0 and v0 are assumed to be phase heads: 1) a) [+ phase]: C0, v(*). b) [- phase]: T0. These heads are assumed to bear uninterpretable φ-features. T0 forms a defective a domain unless it is selected by C0. In other words, if T0 is selected by the phase head C0, it starts bearing a full φ-feature set; otherwise, it cannot inherit the features from C0, which leads to a defective domain allowing exceptional case marking (henceforth, ECM). Accordingly, T0 cannot also delete the features of the goal it enters an agree relation. In this respect, the defective features are Case/T0 features in the sense of Pesetsky & Torrego (2007). At this point, some other studies suggest that the defectivity is peculiar to only phase heads, and that T0 is ruled out of this argumentation: 2) a) [+ [+/- defective]]: C0, v0. b) [- [+/- defective]]: T0. There is an asymmetry in the understanding of defectivity between these two reasoning. The aim of this study is to discuss this asymmetry, and present evidence as to which distinction on defectivity does exist. We employed ECM data in Turkish to discuss the relevant distinction with reference to specific empirical proofs such as long distance scrambling, binding and negative polarity items. The results of the study support in favor of Pesetsky & Torrego (2007).

Abstract: Under high uncertainty and risky environments, the future estimations related to project proposalscannot be certain and really materialized values. It is inevitable that there exists a deviation or gap betweenforecasted values and actual values. Thus, project risk level of the proposal should be analyzedin the assessment phase. Simulation based project evaluation approaches enables to make more reliableinvestment decision since they permits including future uncertainty and risk in analyze process. Inaddition, many times, project proposals are evaluated with more than one conflicted criteria. The aimof this paper is to present a new approach that accounts for multiple objectives for evaluating riskyinvestment projects and determining projects risk level. With the proposed simulation based optimizationapproach, necessity values for project parameters are determined to reach the expected profitabilityof the investment with the minimum initial investment cost. Also, there is an illustrative examplegiven in this study as an application of the proposed approach.

Abstract: Pathology department records were reviewed for all patients who required an operation for symptoms of acute appendicitis between 2000 and 2006. The specimens which were pathologically diagnosed to contain parasites were reevaluated for features of acute inflamation, and parasite type. The medical records were reviewed in detail to achieve a diagnostic score(Eskelinen). Radiologic imaging findings were correlated, if present.Of the 190 appendectomies performed, 6 specimens (3,15%) were found to contain parasites(4 Enterobius vermicularis, 2 Taenia subspecies). Appendectomies with Taenia showed acute inflamation, while acute inflamation was absent in the ones with Enterobius vermicularis. The Eskelinen score was higher than the treshold in two cases with an acute inflamation, and in two without. Ultrasound scans, and a computed tomography scan were performed in 5 patients. In 3 of 4 bland appendices, results favored acute appendicitis.The diagnosis of gastrointestinal parasites is not only made by examining the stool but the diagnosis can be made by histology from surgical specimens. Timely diagnosis and appropriate therapy might prevent probable future complications that may necessitate surgical procedures, at least in some of the patients. The clinical management of these infections is different from that for classical appendicitis.Suspected acute appendicitis is the most frequent cause for emergency operations in visceral surgery, worldwide. The lifetime risk of acute appendicitis for men and women is 8.6% and 6.7%, respectively, however, the lifetime risk of having an appendectomy is 12% for men and 25% for women [1]. A reported 250,000 appendectomies are performed annually, with approximately 15% of these resulting in the removal of normal appendices [2]. A history of migratory pain together with physical findings and leukocytosis is generally percieved as accurate diagnostic clues for children and adults. The overwhelming majority of parasitic infestations of ap

Abstract: A transrectal needle biopsy was indicated due to a high level of prostatic spesific antigen in the blood, and a hard right lobe in rectal examination of a 63-year-old man. 10 examples were taken from each lobe of the prostate. In microscopic examination, all examples from the right lobe contained an adenocarcinoma covering 25 to 50% of the biopsies. Only 4 of the examples from the left lobe contained the tumor, which were all small focuses, composed of 8–10 glands. It was one of the biopsies from the left lobe with a small group of neoplastic glands that attracted our attention. Initially, it was the intraluminal bright, eosinophilic crystalloids as a striking low-power appearance. In daily practice, finding crystalloids in a transrectal needle biopsy with a prostatic adenocarcinoma should not be so astonishing. On the contrary, demonstration of intraluminal crystalloids is common in such cases, and even perceived to be an aid in the diagnosis of prostatic adenocarcinoma [1]. The neoplastic group was also incorporated with a dense infiltration of eosinophils. A carefull re-evaluation of other biopsies confirmed that the feature was peculiar to the aforementioned focus. The reaction, which seemed to be almost totally composed of eosinophils, was clearly restricted to the carcinomatous glandular group. Eosinophils were not only surrounding the focus but also looked like 'attacking' the carcinoma cells. Intraepithelial eosinophils forming occasional small groups could easily be found. The interglandular stroma was rich in free granules, an absolute evidence of eosinophil activation. The co-existance of the eosinophils and the crystalloids certainly pointed to a relationship between two. Actually, the crystalloids were extremely similar to the Charcot-Leyden crystals, that we were familiar with in many allergic situations. It was not unlikely, as these crystals were considered to be an other morphologic hallmark of eosinophil activation. When searched, the crystals coul

Abstract: Private sector investments are the leading factor of housing production today while public agents become a part of the housing market, instead of controlling it. A new consumerist segment in the society has emerged in Turkey after the transition to free market economy, in line with the global tendencies. Luxury housing became an instrument for investment as well as a sign of social status of the inhabitants. Housing production, which is a human right, without public control leads to problems in the field of urban planning. On the one hand, there is a shortage of affordable housing production, on the other development of gated communities surround periphery of the cities. Not only gated communities but also housing development projects in inner cities became the commodities of free market, which constitutes a contradiction with the nature of the planning. The aim of this article is to discuss the gated communities, which epitomize commodified housing production in the frame of consumer society, referring to Istanbul.
