Bekar, Fevziye; Tekin, Perihan Senel
Entrepreneurship is encouraged in every sector in the twenty-first century. In the field of health, nurse entrepreneurship emerges as an important issue in providing health services and improving public health. In this research, the development of entrepreneurial behavior in nursing in the world and a systematic examination of this development within the framework of academic knowledge are aimed. For this purpose, the types of entrepreneurship discussed in the last 10 years of research in the field of entrepreneurship in nursing and the methods, findings and results of these studies were examined. As a result of the search made in databases with high international recognition, 78.761 publications on nurse entrepreneurship were reached in the last ten years, and 30 articles were included in the final review. Classical, social, collective and intrapreneurship were discussed in these studies, which were examined in terms of entrepreneurship typology. As a result of the review, it was seen that the studies in the literature mostly focused on the opportunities and obstacles in front of entrepreneurial nurses. While collective entrepreneurship was included for the first time in the literature, it was found that eco-entrepreneurship and digital entrepreneurship have not yet been the subject of research on nurse entrepreneurship. However, it has been found that more research is needed on the relations between entrepreneurial nurses and non-governmental organizations, the incentives for increasing entrepreneurship and role modeling in entrepreneurship.

Senturk, Esra; Senturk, Murat; Ustundag, Hilal; Aygül, İmdat
By definition, white noise (WN) is a type of sound that consists of a combination of various frequencies. Noise is an important source of environmental stress for humans and other living things and has a strong stimulating effect on light, circadian rhythm, hormonal, and neuro-behavioral levels. When faced with stressful situations, organisms produce a substantial quantity of free radicals, leading to alterations in the oxidative system. The objective of this research is to examine how environmental stressors like WN and light impact the activities of enzymes involved in testicular carbonic anhydrase (CA), catalase (CAT), and glutathione peroxidase (GPx). A total of 18 male Sprague-Dawley rats were divided into three groups. The first was the control group (not exposed to stress, kept at 12/12 light-dark cycle and 24±2°C normal ambient temperature). The second group, known as the WN 60' group, experienced 60 minutes of white noise exposure per day for 14 consecutive days at 90 dB. The third group, referred to as the WN 60' + non daylight group, underwent 60 minutes of white noise exposure at 90 dB combined with 24 hours of continuous light exposure every other day. At the conclusion of the study, the testicular tissues were homogenized and centrifuged, followed by the spectrophotometric measurement of enzyme activities. As a result, when we compared the control group with both WN and WN + light exposure; A decrease was observed for CA enzyme in both applications, and an increase was observed in CAT and GPx enzymes in both applications. As a result, when we compared the control group with both BG and BG + light exposure; A decrease was observed for CA enzyme in both applications, and an increase was observed in CAT and GPx enzymes in both applications.

Dünya genelinde çevresel bozulma, halk ve politika yapıcılar arasında her ülke için artan bir endişe kaynağıdır. Ekonomik büyüme ve doğal çevredeki bozulma arasındaki ilişki ilgili literatürde geniş bir şekilde tartışılmaktadır. Kuznets (1955) tarafından gelir artışı ve gelir eşitsizliği arasındaki U şeklinde bir ilişkiyi temsil etmesi için önerilen Kuznets Eğrisi, daha sonra araştırmacılar tarafından gelir artışı ve çevre kirliliği arasındaki ilişkiyi incelemek için de kullanılmıştır. Zamanla bu yaklaşım Çevresel Kuznets Eğrisi (EKC) olarak adlandırılıp geniş bir literatür tarafından incelenmiştir. EKC hipotezine yönelik makro yaklaşımlar büyük ölçüde tartışılırken, mikro ekonomik yaklaşımlar oldukça azdır. Bu makale, bu bağlamda, çevresel tercihler hakkında bireysel bir bakış açısı oluşturmayı amaçlamaktadır. Çevresel bir gösterge olarak ekonomik büyümeden ziyade çevrenin korunmasına yönelik bireysel önceliği kullanarak, bu tercihi etkileyen bireysel faktörler incelenmiştir. Literatürdeki sınırlı çalışmalar göz önünde bulundurulduğunda, bu çalışma, 1995-2020 dönemi için yüzden fazla ülkeden bireysel gözlemlerden yararlanması bakımından bireylerin çevresel tercihlerini açıklayan öncü girişimlerdendir. Lojistic regresyon yaklaşımından elde edilen bulgular, EKC hipotezini destekleyecek bireysel düzeyde net bir kanıt olmadığını göstermektedir. Buna karşın elde edilen bulgular, sürdürülebilir bir toplum için çok önemli olan çevreci tercihlerin daha iyi anlaşılması için faydalı bilgiler sağlamaktadır. Politika önerileri kapsamında, kadınların güçlendirilmesinin, eğitimin ve iş fırsatlarının bir toplumda sürdürülebilir yeşil bir gelecek için yararlı araçlar olabileceği önerilebilir.

Body composition (BODPOD), agility (Illinois test), visual reaction time (Witty Sem Microgate) and cognitive performance (Stroop Test) of the football players were measured. SPSS v23 was used in the analysis of the data and the significance level was taken as p<0.05. The relationship between normally distributed data was examined with the Pearson Correlation Coefficient. According to the analysis of the data a significant positive correlation was found between cognitive performance and visual reaction time on football players. When the relationship between cognitive performance and agility parameter was examined, no significant relationship was found between the two concepts. There was a significant correlation and a negative correlation between visual reaction time and agility parameters. As a result, when height, body mass index and body fat ratio values increase on football players, visual reaction time increases and performance decreases. Likewise, when the body fat ratio increases, agility time increases and performance decreases.

Hakkıoğlu, Mümin
Victorian poetry, which developed under the influence of profound socio-economic transformations and in company with diverse literary voices and perspectives, includes the poems of the leading figures of the period as well as those of many little-known labouring poets from various professional groups. These poets, most of whom were self-educated, forged their literary perspectives under harsh working conditions, and although they could not write poems with high aesthetic value like the others, they reflected the world they lived in with an intense sensitivity and a sincere language. One of them was the Northumbrian collier Joseph Skipsey (1832-1903), who spent most of his life in the coal mines he entered at seven. In his poems, the traces of communal practices and cultural codes of his region are clearly seen. Even if his living in the country might evoke at first glance that Skipsey is quite close to nature, his relations with it surprisingly exist in a narrowed framework and remain within the confines of traditional narrative forms such as ballad and song. This study aims to reveal the essence of a collier poet’s relationship with nature in his poems within the socio-economic conditions of Victorian England. The main argument of the study is that Skipsey uses nature not as a glorified unity of beings, but as a site of balance and a source of poetic material he refers to in narrating individual emotions, human relations and the realities of miners’ life.
- MakaleAçık Erişim2023An Integration of Self-Conscious Emotion into Public Service Announcement: The Effect of Framing Messages Based on Guilt and Shame-Inducing Strategies on the Intention of Behavior Change
Temel, Ahmet
PSAs (Public service announcements) about social issues have become important tools of persuasion that aimed to direct the public regarding attention to those problems that intended to bring attitude and behavior change. Prevailing studies indicated that message framing that links to a different type of emotional experiences has played different roles in changing the perception of individuals.Specifically, fear appeal-inducing techniques and their effectiveness were the main focus of scientific studies in the area. However, a new line of research indicated that, besides fear, other types of emotions might be important for effective message framing that can bring changes through some forms of persuasion. Following this new development, in this paper, it was proposed that the way the message is framed (either behavior-focused or self-focused) elicits different self-conscious emotions (i.e., guilt and shame) that will differently affect intention for behavior change. The core assumption of the proposed model is that messages framed based on guilt-inducing strategies may lead to intention for behavior change due to the absence of suppression, while messages framed on shame-inducing techniques suppress behavioral change due to the activation of suppression. In line with his, an alternative model was proposed which posits that the potential effectiveness of framing messages based on guilt and shame-inducing techniques varies with respect to a cultural orientation that persists in a given society. In the course of enhancing the proposed model, the paper attempts to draw some examples of message framing based on guilt and shame-inducing and concludes with limitation inherent in the current model.

Claire Keegan’ın Small Things Like These (2021) adlı romanı, İrlanda’daki Magdalen Çamaşırhaneleri bağlamında saflık, kirlilik ve günah keçisi ilan etme gibi kavramları tartış- maya açmaktadır. Roman, ahlak ve ahlaksızlığın cinsiyetçi bir kategoriye indirgenmesini eleştirmekte ve toplumun hem kurbanları hem de kurtarıcıları olarak “düşmüş kadınlara” odaklanmaktadır. Roman aynı zamanda kapitalizm ve eşitsizliğin hüküm sürdüğü İrlan- da’daki New Ross kasabasının sert sosyo-ekonomik ortamını ve kapitalist sistemin kur- banları olan karakterleri de tasvir etmektedir. Keegan, 1996 yılına kadar İrlanda ulusu için ideal kadınların yaratılmasında ve halkın “düşmüş” kadınlardan korunmasında etkili olan Magdalen Çamaşırhaneleri’nin bir taslağını çizerek, dini ve kapitalist etkiler arasındaki suç ortaklığına işaret eder. Kapitalizmin özel mülkiyeti, kârı ve rekabeti öncelediğini ve Hıristiyanlığın sistemin temel ilkelerini yaydığını anıştırarak Hıristiyanlık ve kapitalizm arasındaki ilişkiye vurgu yapar. Anlatı, kapitalizmin kâr arayışının savunmasız grupların sömürülmesine ve marjinalleştirilmesine nasıl yol açabileceğinin, zenginlerin ve güçlülerin çıkarlarını korumak için bir günah keçisi ilan etme sistemini nasıl sürdürdüğünün altını çizmektedir. Dolayısıyla, bu çalışmanın temel amacı, Keegan’ın Small Things Like These adlı eserinde özellikle ötekileştirilen ve manastıra kapatılan kızlar ve diğer karakterler üzerinden örneklenen günah keçisi olgusunu, “mimetik arzu,” “şiddet” ve “günah keçisi mekanizması” ile ilgili teorilerden yararlanarak incelemektir. Çalışma ayrıca, dışlanan ve ulusal ideallere zarar vermekle suçlanan bu kızların hakikate ilişkin nasıl bir ayna işle- vi gördüğünü göstermeyi ve hepsi kapitalizmin güçleri tarafından manipüle edilen kilise, devlet ve toplumun karmaşık etkileşimi içinde gerçek bir toplumsal arınmaya ulaşmanın imkansızlığını ortaya koymayı hedeflemektedir.

Kalkan, Yusuf
The development of High-Technology Exports (HTE) contributes to the increase of competitiveness and growth in national production, the development of commercial and economic cooperation with foreign countries, and the diversification of the economy. In addition, high technology exports reduce the current account deficit of the country's economy. Therefore, high-tech industries have become indispensable for economic development in a country. The aim of this study is to examine the existence of spatial (neighbourhood) relations of countries in high-technology exports. In this study, Exploratory Regression analysis was applied to determine the model that best explains HTE among the variables. Moran Index was used for spatial autocorrelation, Geographical Weighted Regression (GWR) method for spatial regression analysis, and Ordinary Least Squares (OLS) method, to compare with the GWR method. The GWR model established in this study showed that countries have a weak or strong spatial relationship with their neighboring countries in terms of HTE. It has been observed that this spatial relationship is strong in the countries neighboring China, which ranks first in HTE, while the spatial relationship is weak in countries where HTE is low.

Recently the number of buildings and interior spaces has increased, and many systems have been proposed to locate people or objects in these environments. At present, several technologies, such as GPS, Bluetooth, Wi-Fi, Ultrasound, and RFID, are used for positioning problems. Some of these technologies provide good results for positioning outdoors whereas some others are effective for indoor environments. While GPS is used for outdoor localization systems, Wi-Fi, Bluetooth, Ultra WideBand, and RFID are used for indoor localization systems (ILSs). Today, due to the proliferation and extensive usage of Wi-Fi access points, wireless-based technologies in indoor localization are preferred more than others. However, even though the abovementioned technologies make life easier for their users, ILSs can pose some privacy risks in case the confidentiality of the location data cannot be ensured. Such an incident is highly likely to result in the disclosure of users’ identities and behavior patterns. In this paper, we aim to investigate existing privacy-preserving wireless ILSs and discuss them.

Recep Tayyip Erdogan University Zihni Derin Campus, situated at the Eastern Black Sea Region of Turkey, in the province of Rize, was established on a land area of approximately 3.254.430.28 m². It was found that tea, which was thought to be affected by radiation after the nuclear accident at the Chernobyl Nuclear Power Plant, was buried in sacks in this area, which was used as a tea factory before. Therefore, it is crucial to determine the radiation levels in the campus area. In this study, the quantities of artificial (137Cs), and natural (226Ra, 232Th, and 40K) radionuclides, were assessed using a high purity germanium detector (HPGe) in 15 soil samples collected from the Zihni Derin Campus of Recep Tayyip Erdogan University in Rize. For 226Ra, 232Th, 40K and 137Cs the activity values of soil samples varied from 43.78 to 62.58, 29.85 to 41.61, 132.48 to 346.44 and 3.90 to 202.94 Bq kg-1, respectively. Upon comparison with the average global values provided by the UNSCEAR (2000), it was observed that the mean activity values for 226Ra and 232Th in the soil samples were higher. Conversely, the average activity concentrations for 40K and 137Cs were found to be lower than the world average values reported by UNSCEAR (2000). Furthermore, radiological hazard indexes were calculated and compared with internationally acceptable values. This research demonstrates that there are no health concerns for individuals exposed to the soil samples in the study area.

The study aims to assess the economic burden of Covid-19 cases on the payer institution in the context of ambulance services and to investigate the factors affecting costs. Data were obtained from Aydın Provincial Ambulance Service. Cumulative frequency, cumulative percentage and mean (standard deviation) statistics were used for descriptive findings. Logistic regression model was used to examine the factors affecting costs. Covid-19 cases posed a significant economic burden. The cost per case was approximately 466.40 TL and this amount was higher with additional diagnoses. The pandemics created a higher economic burden in 2020. Accordingly, Covid-19 cases accounted for 14.92% of the number of cases and 14.75% of the costs, with an average cost per case of 447.12 TL. In the second year (2021), the economic burden of the pandemic decreased significantly. Accordingly, the share of Covid-19 cases was 7.69%, while the cost share was 7.12%. The average cost in that year was 503.6 TL. Age, triage, reason for call, urban & rural and region variables had a significant effect on costs. There was a statistically significant relationship between advanced age and high costs per case. Covid-19 cases caused a significant economic burden on the payer. It is considered that the implementation of principles and practices related to risk and crisis management for provincial ambulance services will contribute to reducing costs. It is thought that the findings will be useful for other decision makers and policy makers, especially the payer institution.

Ekoturizm, insanların doğal ortamlarda eğlenerek ve doğa harikalarını hayranlıkla izleyerek vakit geçirdikleri bir aktivite türüdür. Doğal güzelliğin en önemli özelliklerinden biri sosyal ve kültürel sakinliği sağlama potansiyelidir. Türkiye'de Mart 2020'de Covid 19 pandemisi salgını haini almaya başlamıştır. Bu çalışma, Giresun'un ekoturizm destinasyonlarını 2018-2021 yılları arasında kaç kişinin ziyaret ettiğini belirlemek amacıyla yapılmıştır. Özellikle 2020 yılında bölgeye gelen turist sayısı azalmıştır. Giresun İli'ne gelen ziyaretçiler, İl Turizm Müdürlüğü tarafından kentin girişinde kayıt altına alınmaktadır. Turizm acentelerinin kayıtları hem yerli hem de yabancı turistlerin tespitini kolaylaştırmaktadır. Giresun iline 2018 yılında 182313 turist ve 2020 yılında 105064 turist gelmiştir. Covid-19 pandemisi nedeniyle turist sayısında iki yılda 77249 azalma olmuştur. Pandemi kısıtlamalarına rağmen yerli turistler temiz hava ve güzel bir yaşam tarzı sağladığı için eko-turizm mekânlarını tercih etmişlerdir. Giresun'a uzak bölgelerden gelen yerli turistler ekoturizm bölgelerinde konaklamışlardır. Bölgemizde çok sayıda ekoturizm destinasyonu bulunmasına rağmen altyapı, ulaşım alternatifleri ve konaklama imkânlarının yetersizliği nedeniyle çok sayıda ziyaretçinin çevre illere yöneldiği de tespit edilmiştir.
