REFLECTIONS OF CONSUMPTION CULTURE IN ADVERTISEMENTS: A READING ON ELIDOR ADVERTISEMENTS IN TURKEY

Consumer culture is generally a reflection of mass culture and popular culture. In this sense, it also includes social changes and transformations. Assuming that consumption is not only limited to 'real needs' but also an act that an individual performs to define himself socially and culturally, it is explained what consumer society means today. Attention is drawn to how individuals in consumer society construct and define themselves through symbolic consumption. In this sense, advertisements in the media are discussed as a tool of consumption culture. The symbols and meanings transmitted through cultural products in the media are analyzed through advertisements. Because advertisements undertake the task of transferring meanings and symbols from the cultural environment to products. In this direction, two commercials of the Elidor brand broadcast in Turkey constitute the sample of the study. The texts of these two commercials are analyzed with the critical discourse analysis method. In the analyzed commercials, it is observed that the brand not only tries to attract the attention of consumers but also tries to gain their trust and respect. As a result of the findings, it is revealed that the advertisements are structured within the framework of 'femvertising' with a representation outside the gender stereotypes of consumer culture. It is seen that while advertising texts seem to reject old ideals, they construct new ideals

Is blue light exposure a cause of precocious puberty in male rats?

PurposeOur study aimed to examine the effects of blue light exposure on prepubertal male rats’ puberty and testis tissue.MethodsEighteen 21-day-old male Sprague Dawley rats were divided into three groups consisting of six rats in each group: Control Group (CG), Blue Light-6 hours (BL-6), and Blue Light-12 hours (BL-12). CG rats were maintained with 12/12-hour light-dark cycles. The rats of BL-6 and BL-12 were exposed to blue light (450-470nm/irradiance level 0.03uW/cm2) for 6 hours and 12 hours, respectively. Rats were exposed to blue light until the first signs of puberty. The ELISA method was used to analyze the serum levels of FSH, LH, testosterone, DHEA-S, leptin, ghrelin, melatonin, glutathione, glutathione peroxidase, and malondialdehyde. Testes were dissected for histomorphological examination.ResultsThe medians of the pubertal entry days of the CG, BL-6, and BL-12 were 38th, 30th, and 28th days, respectively. (p:0.001) The FSH, LH, and testosterone concentrations of all groups were similar. The FSH concentration increased as the LH concentration increased (r: 0.82 p: 0.001). The serum LH concentration increased as serum testosterone, and DHEAS decreased, respectively (r: -0.561, p: 0.01) (r:-0.55 p:0.01). Testicular lengths and weights of the BL groups were smaller compared to CG (p: 0.03),(p: 0.04). GPx was higher for BL-6 and BL-12 than the CG (p:0.021, p:0.024). Testis tissue was compatible with the pubertal period in all groups. As the blue light exposure time increased, spermatogenesis was suppressed, and capillary dilatation and edema in the testis tissue increased.ConclusionOur study is the first to show the effects of blue light exposure on male rats’ puberty process. And we showed that exposure to blue light and the duration of exposure lead to precocious puberty in male rats. The blue light exposure suppressed spermatogenesis, marked vasodilatation in the interstitial area of the testis, and disrupted the integrity of the basement membrane. These findings intensified with increasing exposure time

OCCURRENCE OF LISTERIA SPECIES IN PROCESSING EQUIPMENTS, UNITS AND FROZEN FISH OF FISH PROCESSING FACTORIES

This study was performed to determine the presences of Listeria species in three fish processing factories in İzmir, Turkey. Gilt head seabream (Sparus aurata) has been processed in three factories and exported as frozen to other foreign countries. Listeria spp. expecially Listeria monocytogenes can be a point under consideration of fish processing factories while exporting. For this purpose; A total of 300 samples were examined for Listeria spp in three fish processing factories to determine the contamination levels of fish processing factories with Listeria spp. Samples were taken from units of fish processing factories such as (boxes, processing tables, floors) and equipments (processing coats, gloves) and also processed products (frozen fish). According to the results of this study, Listeria monocytogenes was isolated from 21 or 7% of the samples Listeria ivanovi was isolated from 15 or 5% of the samples and Listeria welshimeri/innocua was isolated from 2 or 0.6% of the samples collected from three factories. Listeria welshimeri/innocua was only isolated from the processing coats (2 or 11%) in factory A. However, Listeria monocytogenes was isolated from boxes (1 or 6%), processing tables (2 or 11%), floor (4 or 22%), processing coats (3 or 17%), gloves (6 or 33%) and frozen fish (5 or 50%) samples taken from the factory C. Except for frozen fish, Listeria ivanovi was isolated from boxes (7 or 39 %), processing tables (3 or 17%), floor (3 or 17%), processing coats (1 or 6 %) and gloves (1 or 6%) taken from the factory B. The incidence of Listeria spe-cies in the production line of fish processing factories points out that contamination can occur during fish pro-cessing stage. Therefore, Listeria spp. must be con-trolled during processing of fishery products. Proper cleaning and sanitation programme of fish processing factories must be applied. Samples must be taken and examined regularly from every units and equipments of fish processing factories to avoid the contamination and spread of Listeria spp in fish processing factories. Cleaning of fish processing equipments and fish pro-cessing units could be very important in order to avoid the occurrence of cross contamination of the fishery products. It must be taken hygienic precautions because of the contamination of Listeria spp. Besides HACCP plan must be applied to prevent recontamination of Lis-teria species to fishery products and it must be also ap-plied to eradicate Listeria species from the fish pro-cessing factories.This study was performed to determine the presences of Listeria species in three fish processing factories in İzmir, Turkey.

Developments in Transformational School Leadership Research: A Systematic Review

The purpose of this study is to outline the nature of empirical base on transformational leadership in Turkey. The present study included a total of 109 graduate theses conducted on school principals’ transformational leadership behaviors between 2000 and 2019 and released in the Council of Higher Education’s (CoHE) database. Results revealed that an important body of research investigated the relationship between transformational leadership and job satisfaction and organizational commitment. Authors’ suggestions to policymakers and practitioners were often about enabling further in-service training activities and providing school principals with various opportunities to study for a master's degree. Suggestions from quantitative studies echoed the need for conducting relevant studies on different samples and expanding qualitative studies to inquiry into transformational leadership. Results, therefore, mirrored the fact that the empirical base on transformational leadership is lacking in terms of mediator and moderator effects of various variables along with the antecedents and results of transformational leadership

The Effect of Digital Activities on the Technology Awareness and Computational Thinking Skills of Gifted Students (eTwinning Project Example)

The aim of this study was to examine the effect of interdisciplinary activities organised online within the scope of an eTwinning project carried out with gifted students on the students’ technology awareness and computational thinking (CT). The study was carried out through web-based tools for a period of 3 months in the year 2020. A single-group pretest-posttest design, one of the pre-experimental designs, was used in the study. The participants were 50 gifted students continuing their education at Science and Art Centres affiliated to the National Education Ministry in 6 different provinces of Anatolia. Quantitative and qualitative methods were used together in the study. A technology awareness and computational thinking scale was chosen as the quantitative data collection tool, while mind maps were used as the qualitative data collection tool. As a result of the research, a significant increase in the participants’ technology awareness and computational thinking was determined in favour of the posttest, while this increase was verified through the mind-mapping technique applied to the students. At the end of the study, the findings were discussed, and recommendations were made for future studies

Evaluation of The Effects of Carob (Ceratonia siliqua L.) Fruits on the Puberty of Rats

INTRODUCTION: This study was planned to determine the effects of carob use on puberty because of the observation of early puberty or pubertal variants due to the long-term use of carob in our clinic. METHODS: Forty-eight Wistar albino rats, on postnatal day 21, were assigned into two groups female (n=24) and male (n=24). Groups were divided into four groups Control, and Carob-150, Carob-300, and Carob-600. Ceratonia siliqua L. extract was given to rats in a 0.5% carboxymethylcellulose (CMC) solution. CMC (0.5%) was given to the control, Ceratonia siliqua L. extract was given 150 mg/kg/day to the Carob-150, 300 mg/kg/day to the Carob-300, 600 mg/kg/day to the Carob-600 by oral gavage. The treatments were performed once daily until the first sign of puberty. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, total testosterone, leptin, glutathione, glutathione peroxidase (GPx), and malondialdehyde were measured by commercial rat-specific ELISA kits. Testis, uterus and ovarian tissue were examined histologically. RESULTS: The median time of preputial separation in male rats was 38th, 31st, 31st, and 31st days in the Control, Carob-150, Carob-300, and Carob-600 groups, respectively (p=0.004). The median day of vaginal opening day was the 39th, 31st, 34th, and 31st days in the Control, Carob-150, Carob-300, and Carob-600 groups, respectively (p=0.059). FSH, LH, testosterone (male), estradiol (female) and leptin levels of the groups were similar. However, GPx levels were higher in male and female animals given C. siliqua extract compared to the Control (male p=0.001 and female p=0.008). Testicular and ovarian tissues were concordant with the pubertal period in all groups. As the dose of Ceratonia siliqua extract increased, it induced spermatogenesis and spermiogenesis, causing abnormal changes, such as ondulation in the basement membrane, capillary dilatation, and increased congestion in males. In females, edema in the medulla gradually increased with increased dosage, and granulosa cell connections were separated in Carob-300 and Carob-600 groups. DISCUSSION AND CONCLUSION: This study demonstrated that C. siliqua caused early puberty and increased spermiogenesis and folliculogenesis. Antioxidant mechanisms were impaired with increasing dose, possibly leading to tissue damage at high doses
