Broadcast Media and Their Social Network Sites: The Case of Palestinian–Israeli Representations and Capabilities
Authors: Shomron Baruch , Schejter Amit M.
Published: December 2019

This study examines how media representations of Palestinian–Israelis differ between broadcast media outlets and their social networking sites, using the “capabilities approach” as the theoretical framework. The study presents a quantitative content analysis comparison of the frequency and context of appearances of Palestinian–Israeli interviewees on all news and current affairs programs broadcast on the five major Israeli broadcast networks over twelve months, as well as the simultaneous appearances of the interviewees on the programs’ Facebook and Twitter accounts. The results suggest that social networking sites of broadcast media are more enabling of capabilities for Palestinian–Israelis relative to the broadcast media themselves. Thus, with changing consumption patterns and technological developments, this analysis points to the importance of examining social networks in addition to traditional broadcast platforms, for a more comprehensive understanding of which capabilities are enabled through traditional mass media as they expand their reach to new technologies.
Masculinity Threat, “Incel” Traits, and Violent Fantasies Among Heterosexual Men in the United States
Authors: Scaptura Maria N. , Boyle Kaitlin M.
Published: December 2019

The current study aims to shed light on how masculinity threat and challenges from women translate into fantasies of mass and gender-based violence. These attitudes are evident among some self-proclaimed “incels,” who blame social liberalism, feminism, and sexually active men for their rejection from women. We developed a measure of “incel” traits, which was administered in an online self-report survey of 18- to 30-year-old heterosexual men in the United States. As hypothesized, stress in one’s inability to live up to norms of masculinity and endorsement of “incel” traits are associated with violent fantasies about rape and using powerful weapons against enemies.
Influence of capsule length and width on heat transfer in capsule-type plate heat exchangers
Authors: Jiang Chen , Zhou Wenxue , Tang Xiaoying , Bai Bofeng
Published: December 2019

Capsule-type plate heat exchanger has the advantages of less deposition and low flow resistance. Based on previous research, numerical studies of capsule-type plate heat exchangers with different capsule lengths and widths for the Reynolds number ranging from 600 to 10,000 are performed. The results show that wake vortices, transverse vortices, and longitudinal vortices generate in the channels by the flow shearing and separation. The vortices promote the swirl and flow destabilization, exchange the fluid between the boundary layer and the mainstream, and thus enhance the heat transfer in the capsule-type plate channels. Wake vortices transform to longitudinal vortices with increasing Re. The number of the longitudinal vortices decreases and the size of the longitudinal vortices increases with increasing Re or the decreasing length−width ratio of the capsule. In addition, Nusselt number and friction factor decrease with the increasing length−width ratio of the capsule.
Association of chemotactic chemokine ligand 5 rs2107538 polymorphism with tuberculosis susceptibility: A meta-analysis
Authors: Sheng Yun-Feng , Qi Qi
Published: December 2019

A meta-analysis was carried out in this study by summarizing relevant research to evaluate the relationship between rs2107538 polymorphism in the chemotactic chemokine ligand 5 (CCL5) gene and tuberculosis (TB) susceptibility. Published studies were retrieved from PubMed, Embase, and CNKI databases using the keywords ‘CCL5’, ‘TB’, and ‘polymorphism’. Nine studies involving 2584 patients with TB and 2265 controls were included in the current meta-analysis. The combined results suggested that the CCL5 rs2107538 polymorphism was correlated with TB susceptibility (recessive model: OR = 1.45, 95% CI = 1.02–2.07). Subgroup analysis according to race indicated that such correlation could be detected in Caucasians (CT versus CC: OR = 1.53, 95% CI = 1.20–1.95; dominant model: OR = 1.58, 95% CI = 1.25–1.99), but not in East Asian, South Asian, and South African populations. In conclusion, the results of our meta-analysis suggest that CCL5 rs2107538 polymorphism might contribute to the risk of TB, especially in Caucasians. Well-designed studies with more subjects will be required for further validation of these results.
Observational physical activity in public open spaces: environmental determinants of physical activity intensity levels in Iran
Authors: Aliyas Zeinab , Jafari Keyvan
Published: December 2019

Public open spaces play an important role in promoting physical activity (PA). This study aimed to describe user characteristics of public open spaces (POSs) given the type of location and levels of PA. The study also evaluated the relationship between the environmental determinants of POSs and PA intensity. The study used observational data to measure environmental determinants and obtain information on users and their activity levels in the POSs of Darab in Iran. Out of 13,342 individuals observed, the proportion of men was slightly higher than that of women. More than half of the users observed in the community parks performed vigorous activities. Children and teenagers were found more often than other age groups doing vigorous activities. Most of the observed users performed vigorous activities in the evening and sedentary activities during weekends. Seniors were more sedentary than the other groups. Greater size, and better facilities and aesthetics of POSs increased the odds of being more active. However, a higher number of incivilities was associated with a greater chance of walking and lower odds of performing vigorous activities. As the quality of POSs contributes to PA levels, stakeholders should consider the quality of such spaces to improve retrofitting and designing POSs to maximize activity levels.
‘I think one of the ways they will help is to create awareness’: primary school teachers’ perceptions of cardiovascular diseases in Nigeria
Authors: Udeh Kingsley , Nwakasi Candidus , Fulton John
Published: December 2019

The increasing incidence and prevalence of non-communicable diseases is a major global health concern. Cardiovascular diseases (CVDs) account for the highest percentage of deaths related to non-communicable diseases, and low and middle-income countries (LMIC) face the highest burden of CVDs. Understanding the knowledge and perception of CVDs and their risk factors in an LMIC such as Nigeria may play an important role in cardiovascular health promotion and improvement plans to reduce CVD-related deaths. A qualitative study was conducted using semi-structured interviews to gain an in-depth understanding of some personal and sociocultural views on CVDs and their risk factors. The participants were purposively sampled primary school teachers in South-Eastern Nigeria. Thematic analysis approach was used for data analysis. The study findings include knowledge of heart disease, perceived causes and risk factors of CVDs, spirituality, and the way forward. Overall, the knowledge of CVDs in the setting was found to be related to the psychosocial nature of the participants; the effectiveness of any intervention needs to take these factors into consideration. For example, health policies for CVD health education and awareness should be tailored to address some of the issues of belief, values, and religion, as mentioned in the study.
Exploring Parental Experiences of Using a Do-It-Yourself Solution for Continuous Glucose Monitoring Among Children and Adolescents With Type 1 Diabetes: A Qualitative Study
Authors: Elbalshy Mona , Boucher Sara , Crocket Hamish , Galland Barbara , MacKenzie Craig , de Bock Martin I. , Jefferies Craig , Wiltshire Esko , Wheeler Benjamin J.
Published: December 2019

Background:

MiaoMiao (MM) is a Bluetooth transmitter, which when paired with a smart phone/device, converts the Abbott FreeStyle Libre flash glucose monitoring system into a Do-It-Yourself (DIY) continuous glucose monitor (CGM). Families are increasingly adopting DIY CGM solutions, but little is known about parent and child experiences with these add-on technologies. We aimed to explore experiences of families using MM-CGM including challenges faced and their advice to others who may choose to use the technology.

Methods:

Between May and July 2019, we conducted 12 semistructured interviews (in person or via video conference) with parents of children (aged ≤16 years) with type 1 diabetes using MM-CGM. Interviews were audio recorded; professionally transcribed and key themes were identified through thematic analysis.

Results:

Overall, parents used MM-CGM to proactively manage their child’s blood glucose. In all participants, this led to a perceived decrease in frequency of hypoglycemia. Participants reported that the visibility and easy access to blood glucose readings, glucose trends, and customized alarms on parent’s phones decreased their disease burden and improved their sleep quality. Common barriers to using MM-CGM included difficulty of the setting up process, connectivity issues, and lack of support from medical teams.

Conclusion:

This study highlights the potential feasibility of using a DIY CGM system like MM-CGM, which could be an empowering and cost-effective tool for enabling remote monitoring of blood glucose in real time.
A Remarkable Depth Confusion in Images of the Incomplete Statues of Bruno Catalano
Authors: van Lier Rob , Ekroll Vebjørn
Published: December 2019

Images of Bruno Catalano’s sculptures of incomplete bodies give rise to a remarkable depth confusion in which the background is partly pushed to the front. We argue that this confusion is related to what happens in the Kanizsa square, although the effect in the images of Catalano’s sculpture appears to be driven by knowledge-based processing.
Scrutinizing the Great Acceleration: The Anthropocene and its analytic challenges for social-ecological transformations
Authors: Görg Christoph , Plank Christina , Wiedenhofer Dominik , Mayer Andreas , Pichler Melanie , Schaffartzik Anke , Krausmann Fridolin
Published: December 2019

Despite considerable advancements over the last couple of years, research on the Anthropocene still faces at least two challenges: (1) integrating different approaches from natural, social and cultural sciences, and (2) clarifying the political relevance of this concept. To address these challenges, we propose an interdisciplinary approach from Social Ecology and Political Economy which combines research on social metabolism with a historical approach to capitalist development. We argue that such an interdisciplinary approach can help to better understand the Great Acceleration of production and consumption and the related surge in global resource flows. The observation of such an acceleration in the physical growth of societies, in turn, is perceived as the most convincing argument to explain fundamental shifts in the state and functioning of the Earth system, the Anthropocene. Our approach emphasizes that the Great Acceleration was not homogeneous, neither in space nor in time. Instead, spatial varieties and different historical trajectories must be considered which allow for the differentiation of two phases of accelerated resource use, taking place in different world regions. In this article, we propose an integrated research framework for the study of the Great Acceleration, illustrate the insights to which its application leads and discuss the political relevance of the Anthropocene for further research on social-ecological transformations.
Progestogens are the problem in hormone replacement therapy: Time to reappraise their use
Authors: Manyonda Isaac , S Talaulikar Vikram , Pirhadi Roxanna , Onwude Joseph
Published: December 2019

Combined (estrogen and a progestogen) hormone replacement therapy (cHRT) is associated with an increased risk of breast cancer, while estrogen replacement therapy is not. Whatever the underlying mechanism, it is the progestogen in cHRT that seems to increase the risk. Fear of breast cancer is a major limiting factor in the use of hormone replacement therapy, and when women discontinue cHRT because of side effects, the latter are often attributable to the progestogen component. cHRT is given to women with an intact uterus to protect against the effects of un-opposed estrogen such as an increased risk of endometrial cancer. Estrogen replacement therapy suffices for women with a prior hysterectomy. There is a clear distinction in risk and side effect profile between cHRT and estrogen replacement therapy. Apart from being the most effective treatment for menopausal symptoms, estrogen prevents osteoporosis, and may also have a potential role in prevention of Alzheimer’s Dementia, now the biggest killer of women in the United Kingdom. Evidence also suggests that progestogens could compromise the dementia-preventative effect of estrogen. Given the immense therapeutic and preventative potential of estrogen, the use of progestogens in cHRT needs re-appraisal. The levonorgestrel intrauterine system (LNg-IUS) could reduce breast cancer risk while protecting the endometrium. Other approaches to the safe use of progestogens await research.

Authors: Hajesmaeel-Gohari Sadrieh , Bahaadinbeigy Kambiz , Tajoddini Shahrad , R Niakan Kalhori Sharareh
Published: December 2019

Objective

Drug poisoning is the most prevalent type of poisoning throughout the world that can occur intentional or unintentional. Standard way for data gathering with uniform definitions is a requirement for preventing, controlling and managing of drug poisoning management. The purpose of this study was to develop a minimum data set, as an initial step, for a drug poisoning registry system in Iran.

Methods

This was descriptive and cross-sectional study that was performed in 2019. As the first step a comprehensive literature review was performed to retrieve related resources in Persian and English languages. For the second step the medical records of drug poisoning patients at Afzalipour hospital affiliated to Kerman University of Medical Sciences were assessed. Related data from these two steps were gathered by a checklist. Finally, a questionnaire that was created based on the checklist data elements and had three columns of ‘essential,' ‘useful, but not essential', and ‘not essential' was used to reach a consensus on the data elements. Then the content validity ratio and the mean of experts’ judgments were calculated for each data element. The Cronbach’s alpha value for the entire questionnaire was obtained 0.9.

Results

The minimum data set of a drug poisoning registry system was categorised into the administrative part with three sections including 32 data elements, and clinical parts with six sections including 81 data elements.

Conclusion

This study provides a minimum data set for development of a drug poisoning registry system. Collecting this minimum data set is critical for helping policy makers and healthcare providers to prevent, control and manage drug poisoning.
The Impact of a Cycled Lighting Intervention on Nursing Home Residents: A Pilot Study
Authors: Giggins Oonagh M. , Doyle Julie , Hogan Ken , George Mable
Published: December 2019

Purpose:

Achieving adequate levels of illumination to stimulate the circadian system can be difficult in a nursing home. The aim of this study was to examine the impact that a 4-week cycled lighting intervention had on activity, sleep, and mood in older adults living in a nursing home.

Patients and methods:

Ten residents were given an activity monitor to objectively measure activity and sleep, and subjective mood scores were also recorded during the study period. The cycled lighting intervention was designed to mimic normal natural daylight.

Results:

Some participants responded positively to the lighting intervention showing improvements in activity levels, sleep, and mood, while others showed no change or a continued decline.

Conclusion:

Although the results are inconclusive, a cycled lighting intervention remains a potentially promising intervention in the nursing home setting. Further studies with more robust measurements and a larger, more homogeneous cohort are required to investigate this further.

Authors: Shibahara Fumitoshi , Mizuno Takahiro , Shibata Yoshifuru , Murai Toshiaki
Published: December 2019

To investigate the catalytic utility of the imidazo[1,5-a]pyrid-3-ylidene (IPC) ligand, Pd-catalyzed transfer semihydrogenation of alkynes with formic acid as a hydrogen source was conducted. The steric bulkiness of the substituent on N2 affected the configuration of the π-allyl moiety of the precatalyst of IPC-Pd-π-allyl complexes and the robustness of the catalytic process. The catalytic activities of IPC-Pd complexes were clearly higher than those of conventional NHC-Pd complexes.
Pockels-effect-based adiabatic frequency conversion in ultrahigh-Q microresonators
Authors: Minet Yannick , Reis Luis , Szabados Jan , Werner Christoph S. , Zappe Hans , Buse Karsten , Breunig Ingo
Published: December 2019

Adiabatic frequency conversion has some key advantages over nonlinear frequency conversion. No threshold and no phase-matching conditions need to be fulfilled. Moreover, it exhibits a conversion efficiency of 100 % down to the single-photon level. Adiabatic frequency conversion schemes in microresonators demonstrated so far suffer either from low quality factors of the employed resonators resulting in short photon lifetimes or small frequency shifts. Here, we present an adiabatic frequency conversion (AFC) scheme by employing the Pockels effect. We use a non-centrosymmetric ultrahigh-Q microresonator made out of lithium niobate. Frequency shifts of more than 5 GHz are achieved by applying just 20 V to a 70-µm-thick resonator. Furthermore, we demonstrate that with the same setup positive and negative frequency chirps can be generated. With this method, by controlling the voltage applied to the crystal, almost arbitrary frequency shifts can be realized. The general advances in on-chip fabrication of lithium-niobate-based devices make it feasible to transfer the current apparatus onto a chip suitable for mass production.

Authors: Malik Mohd Maaruf Abdul , Othman Faizah , Hussan Farida , Shuid Ahmad Nazrun , Saad Qodriyah Mohd
Published: December 2019

Background and Aim: Both virgin coconut oil (VCO) and tocotrienol-rich fraction (TRF) are rich in antioxidants and may protect the bone against bone loss induced by ovariectomy and high-fat diet. The study aimed to determine the protective effects of combined therapy of VCO and TRF on osteoporosis in ovariectomized (OVX) rat fed with high-fat diet.

Materials and Methods: Thirty-six female Sprague-Dawley rats were divided into six groups: Sham-operated (SHAM), OVX control, OVX and given Premarin at 64.5 μg/kg (OVX+E2), OVX and given VCO at 4.29 ml/kg (OVX+V), OVX and given TRF at 30 mg/kg (OVX+T), and OVX and given a combination of VCO at 4.29 ml/kg and TRF at 30 mg/kg (OVX+VT). Following 24 weeks of treatments, blood and femora samples were taken for analyses.

Results: There were no significant differences in serum osteocalcin levels between the groups (p>0.05), while serum C-terminal telopeptide of Type I collagen levels of the OVX+VT group were significantly lower than the other groups (p<0.05). The dynamic bone histomorphometry analysis of the femur showed that the double-labeled surface/bone surface (dLS/BS), mineral apposition rate, and bone formation rate/BS of the OVX+E2, OVX+T, and OVX+VT groups were significantly higher than the rest of the groups (p<0.05).

Conclusion: A combination of VCO and TRF has the potential as a therapeutic agent to restore bone loss induced by ovariectomy and high-fat diet.

Pathogenetic features of immunological disorders in women with thyroid peroxidase antibodies presence and their effect on infertility treatment by in vitro fertilization (IVF)
Authors: Druzhinina Aleksandra S. , Vitiazeva Irina I.
Published: December 2019

Autoimmune thyroiditis (AIT) is the most common thyroid disease among women of fertile age. An increase of thyropercosidase antibodies (TPO-Ab) occupies one of the leading positions among other autoantibodies in patients with idiopathic infertility. Stimulation of superovulation in assisted reproductive technology (ART) programs leads to thyroid overstimulation, relative hypothyroxinemia and an increase of thyroid stimulating hormone (TSH) level in women with positive TPO-Ab carrier state, leading to a decrease in the reserve capacity of the thyroid affected by the autoimmune process. There is a large number of studies concerning the effect of autoimmune thyroid diseases on the infertility treatment outcomes in ART programs, but the results are contradictory. One of the hypotheses is that TPO-Ab affect the embryo implantation process in the uterus, based on an imbalance of cytokine production by T-helper type 1, 2, and 17, which are not easy to correct by classical hormone replacement therapy with levothyroxine. Nowadays, the immunological mechanisms of these disorders are not well investigated.
Psychometric properties of the Student - University Match (sum) Questionnaire in Turkish
Authors: Avcı Dilek , Doğan Türkan
Published: December 2019

The aim of this research is to adapt the Student-University Match (SUM) Questionnaire into Turkish. The scale was developed by Wintre vd. (2008) in order to measure how well-matched freshmen students perceived themselves as compatible with universities during their transition period to university at their first year. The scale measures the matching characteristics of the student's individual goals and needs and the opportunities provided by the university. The scale consists of 17 items within the scope of the social dynamics of the university, academic difficulties, program eligibility and physical environment. The high scores obtained from the scale indicate the perception of student-university positive match whereas the low scores indicate the negative-matching perception. In parallel to the development of the original scale, data from the 698 first year university students who began education in different universities of Turkey. SUM Questionnaire, University Life Scale and Personal Information Form were applied. Cronbach’s Alpha Reliability Coefficient was determined as .85 for Social, Personal and Environmental Match sub-dimension of the 17 items of SUM; it was determined as .83 for Academic and Intellectual Match sub-dimension, and .90 for the whole scale. Obtained findings support that the items of the SUM Scale homogeneously measure the same psychological structure at the level of whole scale and sub-dimensions, and it is a valid and reliable scale.

Authors: Chen Yen-Jen , Tsai Han
Published: December 2019

This study provides a low-cost and high-availability database management system architecture for general Small/Medium Enterprises (SMEs) to backup database data access. To prove that the proposed architecture can support the high availability of the database, and can effectively avoid data loss in memory caused by failovers, this study applies the main test method of powering off the virtual machine and verified three cases on two commonly used databases MySQL and PostgreSQL: Case 1 proves that this study combines the database native disaster recovery mechanism to effectively achieve high availability of the database. Case 2 proves that it effectively controls the WAL (Write Ahead Log) of the PostgreSQL database and Redo log mechanism of the MySQL database, so that data correctness is maintained during failovers. Case 3 proves that it can analyze and control the timing of the database in writing data in the cache memory to the hard disk. This study also designed a failover process to avoid data loss during failovers due to no enough time to write the data in the cache memory back to the hard disk; and finally to realize the high-availability of the database management system architecture in a practical way.

Is Internet Access a Matter of Freedom of Expression? Some Examples from Ukraine
Authors: Kelichavyi Bogdan , Metcalf Katrin Nyman
Published: December 2019

Freedom of expression does not only mean absence of censorship or other restrictive content laws—it also means that people have real access to communication. Nowadays, internet is a key means of communication. In this article we explain the relevance of access to internet from legal, practical and market aspects for freedom of expression. To illustrate the question, we present the situation in Ukraine. We look at legislation, including restrictions due to national security—availability, affordability and accessibility of internet. Ukraine is an interesting example of a mixture of very positive indicators and some remaining restrictions.

Authors: Jachowicz Tomasz , Gajdos Ivan , Krasinskiy Volodymyr
Published: December 2019

The paper reports the experimental results of a study investigating the effect of different contents of a mineral filler on the rheological properties, p-v-T, of polypropylene. Using the pvT100 apparatus, we measured specific volume under isobaric cooling at different pressures for pure polypropylene and chalk-filled polypropylene (10 wt%, 20 wt% and 30 wt%). Next, we employed computer methods to determine the coefficients of a mathematical model describing the variations in specific volume in a function of temperature and pressure. The model was used in the numerical simulations of injection molding and shrinkage processes.
Optimization of shape memory alloy braces for concentrically braced steel braced frames
Authors: Babaei Sasan , Zarfam Panam
Published: December 2019

Expanding the use of smart braced frames to govern the seismic response of structures by providing ductility and elasticity has been hampered and delayed by cost indexes. The braces in frames comprise two segments of expensive shape memory alloys (SMAs) and high-strength steel with high stiffness. These smart materials can reduce seismic damage by providing stiffness, yielding, and phase shifting. In this study, the length of the SMA segments in three- and six-story frames (applied either at all floors or as part of a dual system) was increased to determine the optimal length at a constant period. Performance levels and fragility curves were obtained to evaluate the seismic behavior of the optimized frame. The response modification factor determined based on the static pushover, incremental nonlinear dynamic analysis, and linear dynamic analysis suggests the ductility and over-strength of the optimized frame. The probability of being in or exceeding each damage state was determined with a Monte Carlo analysis and was acceptable and in accordance with previous deterministic analysis results.
Physiological persona differences based on stress and inflammation between meditators and healthy controls
Authors: Magan Dipti , Yadav Raj Kumar
Published: December 2019

Background

Nowadays, yoga is endorsed and advised routinely to stay fit and healthy, as well as control many chronic diseases including diabetes type 2, hypertension, coronary artery diseases, etc. Now, our assumption is that those who do regular yoga have different persona than who do not do yoga regularly. We planned to test our hypothesis scientifically, and therefore baseline physiological characteristics with stress and inflammation levels in long-term and short-term meditators and healthy novice controls were analyzed.

Methods

In this retrospective analysis, 97 male participants were included for their Baseline analysis. Fifteen apparently healthy subjects practicing preksha meditation (since >5 years, at least 5 days a week) were included as long-term meditators (LTMs); 58 subjects who attended one of our short-term yoga-based lifestyle intervention programs for 2 weeks were included as short-term meditators (STMs); 24 male novice subjects, who did not participate in any yogic intervention, were included as healthy controls. Here, we analyzed the Baseline plasma levels of stress and inflammatory markers, cortisol, β-endorphin, interleukin (IL)-6 and tumor necrosis factor (TNF)-α in long-term meditators vs. short-term meditators vs. healthy controls.

Outcome measures

The study parameters body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), plasma levels of stress and immune markers, cortisol, β-endorphin (β-Ed), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), were assessed in all the three groups at baseline.

Results

Significant (p<0.05) differences were observed at baseline for plasma levels of stress and inflammatory markers as well as body mass index and systolic blood pressure among LTM vs. STM vs. healthy controls.

Conclusions

Our observations suggest that the subjects who do regular yoga-meditation practice have better stress & inflammation status than comparable age matched healthy controls.
Kant the Naturalist
Authors: Louden Robert B.
Published: December 2019

Kant is widely admired – and sometimes also widely criticized – as the founding father of transcendental philosophy. But in much of my own writing, I have been concerned with a very different Kant: an impure rather than a pure Kant, ana posteriorirather than ana prioriKant, a naturalistic rather than a transcendental Kant. This other Kant has often been overlooked by professional philosophers, and when not overlooked, he is often regarded as shallow and unoriginal. My aim in this paper is to demonstrate not only the existence but also the importance and originality of Kant, the naturalist. Without Kant’s naturalism, we lack what he called the empirically-informed “eye of true philosophy” that gives its possessors a necessary “broadened way of thinking” and provides philosophy with “dignity, i. e., an absolute worth.”

2000 yılı ve sonrası dünyaya gelen nesli temsil eden kuşak Z kuşağı genel olarak kendisinden önceki kuşaklardan sosyolojik, kültürel ve daha küresel bir ortamda dünyaya gözlerini açmıştır. Z kuşağı tüketiciler şimdiye kadar ki nesillerin çok ileriki yaşlarda tanışma imkânı bulduğu teknolojik imkânlarla neredeyse bebeklik çağında tanışmıştır. Ayrıca daha önceki nesillerin görmediği bir bolluk çağında yaşamını sürdürmektedir. Bütün bu gelişmelerin şüphesiz Z kuşağının tüketim davranışları üzerinde önemli değişimlere neden olduğu düşünülmektedir. Bu çalışmanın amacı Z kuşağı tüketicilerin hedonik (hazcı) tüketim davranışlarını demografik özellikleri bağlamında incelemektir. Araştırma sonucunda katılımcıların cinsiyetleri, yaşları, alışveriş sıklıkları, babalarının eğitim düzeyleri, en uzun süre yaşadıkları yerleşim yerleri arasında hedonik tüketim davranışları açısından farklılıklar tespit edilmiştir.

Günümüzde çoğunlukla gelenekselden internete doğru kayan satın alma karar sürecinin en etkileyici faktörlerinden biri de hiç kuşkusuz sosyal medya fenomenleridir. Satın alma karar sürecinin ihtiyaç hissedilmesi anından başlayarak satın alma sonrasına kadar uzanan her aşamasında sosyal medya fenomenlerinin etkilerini görmek mümkündür. Bu çalışmanın amacı da sosyal medya fenomenlerinin satın alma karar sürecindeki rolünü ortaya koymaktır. Bu bağlamda 15 Mayıs- 1 Haziran 2019 tarihleri arasında internet üzerinden çeşitli sosyal medya ortamlarında kolayda örnekleme yöntemi ile 448 kişiden anket yöntemi ile veri toplanmıştır. Araştırma sonuçlarına göre, katılımcıların sosyal medya fenomenlerini takip etme nedenleri arasında ilk üç sırada eğlenmek, çeşitli konular hakkın da bilgi sahibi olmak, merak etmek gibi nedenler yer alırken, sosyal medya fenomenlerinde bekledikleri özellikler ise sırasıyla samimi olması, etkileme gücüne sahip olması ve ilgi çekici olması öncelikli olmaktadır. Katılımcıların sosyal medya fenomenlerinden etkilenerek en çok satın aldıkları ürünler ise giyim ürünleri ve kozmetik ürünlerdir. Ayrıca araştırma sonucunda ortaya çıkan bir diğer bulgu ise, sosyal medya fenomenlerine yönelik algıların satın alma karar sürecinde etkili olduğudur.
İŞ SAĞLIĞI VE GÜVENLİĞİ UYGULAMALARININ GEÇERLİĞİNİN TEST EDİLMESİ VE ÇALIŞANLARIN ÇEŞİTLİ DEMOGRAFİK ÖZELLİKLERİNE GÖRE BENZERLİK YA DA FARKLILIKLARININ İNCELENMESİ

Bu çalışmada İş Sağlığı ve Güvenliği alanındaki çeşitli uygulamalarının ölçeklendirilmiş sorular ile elektrik ve elektronik sektöründe beyaz yakalı çalışanlar üzerinde önce geçerliliği daha sonra da güvenilirliği test edilmiştir. Altı temel başlıkta ölçülmeye çalışılan bu uygulamalar; Güvenlik Prosedürleri ve Risk Yönetimi(GPRY), Güvenlik ve Sağlık Kuralları (GSK),  İlk Yardım Desteği ve Eğitim (İDE), İş Kazalarını Önleme (İKÖ), Örgütsel Güvenlik Desteği (ÖGD), Raporlama Kültürü (RK)’dür. Hem geçerlilik sonuçları hem de güvenirlilik sonuçları oldukça anlamlı ve kabul edilebilir seviyelerde çıkan bu çalışmada, ikinci aşama olarak elde edilen uygulama faktörlerinin kişilere ait çeşitli demografik özelliklere göre farklılık yaratıp yaratmadığı incelenmiştir. Elde edilen en temel bulgular; örgütsel güvenlik desteği alt boyut puanlarının katılımcıların işletmedeki pozisyonuna, güvenlik prosedürleri ve risk yönetimi alt boyut puanlarının katılımcıların toplam çalışma süresine; güvenlik ve sağlık kuralları ile raporlama kültürü alt boyut puanlarının katılımcıların haftalık çalışma saatine; örgütsel güvenlik desteği alt boyut puanlarının katılımcıların işe ulaşım şekline; güvenlik prosedürleri ve risk yönetimi ile güvenlik ve sağlık kuralları alt boyut puanlarının çalışma ortamının fiziksel sağlığa olumsuz etkisine; güvenlik prosedürleri ve risk yönetimi, güvenlik ve sağlık kuralları, iş kazalarını önleme alt boyut puanlarının çalışma ortamının ruhsal sağlığa olumsuz etkisine göre anlamlı farklılık gösterdiği tespit edilmiştir. Ancak bunların dışında kalan İş sağlığı ve güvenliği uygulamalarına ortalama puanlarının cinsiyet, medeni durum, yaş grupları, öğrenim düzeyi dahil diğer tüm demografik özelliklere göre anlamlı farklılık göstermediği (p>0,05) tespit edilmiştir.
THE COMBINED EFFECT OF LEADER-MEMBER EXCHANGE AND LEADER OPTIMISM ON FOLLOWER JOB OUTCOMES
Authors: BAKER Nevra
Published: December 2019

Leader-member exchange theory is one of the most widely researched leadership theories, and a substantial number of former studies have investigated the effect of leader-member exchange on different follower job outcomes. However, there is a lack of research in the literature on the combined effect of leader-member exchange and leader emotional expressivity on follower job outcomes. The aim of this study is to contribute to the leadership and emotions literature by investigating the combined effect of leader-member exchange and the leader emotional expressivity of optimism on follower job outcomes of affective organizational commitment, trust in leader, and job satisfaction. In order to test the hypotheses of the study, an experiment was undertaken in which four imaginary leader types were described. After reading the leader descriptions, respondents were given a survey about their self-foreseen affective organizational commitment, trust in leader, and job satisfaction, with the assumption that they were actually working with the imaginary leader. The findings of the study suggest that both high LMX and low LMX leaders who displayed optimism aroused higher levels of the three follower job outcomes than their counterparts who did not display optimism.

AN ANALYSIS ON THE ROLE OF SOCIAL NETWORK STRUCTURE IN IT OUTSOURCING PROJECT REALIZATION
Authors: ÖZDENİZCİ KÖSE Büşra
Published: December 2019

Information Technology (IT) outsourcing practices are increasing due to valuable strategic benefits such as cost savings, value-added activities, high quality systems, risk reduction, efficiency and competitiveness, compliance and security, and more. Today, managing the outsourcing relationship between client and vendor has become one of the significant issues to be considered for the sustainability of outsourcing interaction and the success of project outcomes. This study examines the importance of social interaction structure on project success and examines how relationship dynamics are realized between the client and vendor side through a case of “failed” IT outsourcing project. This case study puts forward the importance of IT outsourcing on project success with an interpretive analysis. In this regard, the study examines the IT outsourcing project participants’ needs, the communication dynamics and the social network model in terms of structural and tie properties; and sheds light on the hidden issues of failed IT outsourcing projects for practitioners and researchers.
