Historical Change of Winter Chill Accumulation in Some Regions of Turkey

Deciduous fruit trees need to be exposed to low winter temperatures for a certain period time to produce regular crops. In addition to the effects of global warming in many other areas, its effect on cold accumulation is also a reason of concern. As a result, many studies have been carried out in important horticultural areas around the world on the impact of climate change on cold accumulation. In this study, historical changes of cold accumulation calculated using five models were examined in 12 locations in Turkey for the first time. Results show that there was no significant trend in cold accumulation in the provinces of Ankara, Bingöl, Diyarbakır, Malatya, and Tunceli. In some locations, the significance, magnitude, and direction of the chilling trend differed according to the model used. All five models used in the study indicated significant decreases in winter chill accumulation in Şanlıurfa, a site with relatively mild winters. In Erzincan, which has relatively cold winters, increasing trends were detected in cold accumulation calculated according to Utah, Modified Utah, and Positive Utah models. Results show that serious consequences may arise related to the chilling requirement of deciduous fruit trees, especially in regions with mild winters.

Estimating Regional Aggregate Economic Value of Forest Recreation Services with Linked Travel Cost Model

Multi-site linked travel cost models answer the need for aggregate demand and economic value estimations that consider the attributes of all forest recreation sites in a region and the preferences of visitors at the regional level. This study aimed to predict the aggregate value of forest recreation services in Ankara Province, Turkey, with a discrete choice-count data-linked model in the context of current and changing levels of forest attributes. In the first stage, the site choice model was predicted with the random parameter logit model; in the second stage, the trip demand model was estimated with the negative binomial model. The expected consumer surplus per trip derived from the first model was used as the link variable in the second model. The expected consumer surplus per trip of 14 forest recreation sites was estimated at 137.34 TL, and the annual aggregate consumer surplus per capita was estimated at 156.59 TL—a total of 13.49 million TL in the study area. This study predicts the total benefit will increase by 65% if the development stage of stands at recreation sites increases by two stages, degraded stands are improved, stands have a normal canopy, and the camping facilities are improved.

However, no significant difference was found in the dependent variables related to gender.

Radioactivity survey and risk assessment study for drinking water in capital city Ankara, Turkey

ABSTRACT In this study, the activity concentrations of gross alpha and gross beta in 125 drinking water samples (16 tap and 109 spring waters) collected from Ankara province were measured using a gas proportional α/β counter. The average (range) activity concentrations of gross alpha and gross beta were determined as 105 (20–495) mBqL−1 and 195 (70–850) mBqL−1, respectively. Average annual effective dose to adults caused by ingestion of water samples was estimated as 74.1 ± 43.2 µSv y−1. The average estimated cancer risk value depending on irradiations was calculated as 3.8 × 10−4 and 2.6 × 10−4 for the region using the nominal probability coefficients recommended by ICRP 60 and ICRP 103, respectively. Annual effective dose values in 10.4% of samples exceeded the limit values suggested by WHO for drinking waters in terms of beta activity and this was 0.8% for alpha activity. Moreover, contribution of 40K to the gross beta activity in drinking waters of the region was determined as 47%.

Sosyal Ağ Bağlantılarının Bireysel Performans Üzerindeki Etkisi: Akademisyenler Üzerine Bir Çalışma

Many behaviors of human being, who is a social being, in the organization are affected by the social network connections. The aim of this study is to reveal whether the social network connections of the actor in the organization have an effect on individual performance, which can be considered as the antecedent of many behavioral variables in the management and organization research literature. The absence of a holistic study in the literature that deals with positive and negative social network connections together constitutes the originality of the study, and it is considered that both the methodology and the theoretical infrastructure of the study will contribute to the literature. The social network of the study consists of 37 academicians working in a faculty affiliated to the university operating in Ankara Province. Within the scope of the study, first the network mechanism of the actors was revealed with the UCINET program, then the individual performance scores of the actors, which were measured regularly within the framework of the criteria determined by the university, and the network analysis obtained. Correlation and regression analyzes were performed to reveal the relationship between the findings through the SPSS program. As a result of the analyzes, quite remarkable results were obtained. Accordingly, it was determined that the performance scores of the central actor with positive social network connections, in other words, the most liked actor in the network, were low; it was determined that the actor with the most negative social network connections was the actor with the highest individual performance score.

Armut ağaçlarında Cacopsylla pyri (L.) (Hemiptera: Psyllidae) mücadelesinde sarı yapışkan tuzakların kullanımı

This study investigates the applicability of a mass trapping method using yellow sticky traps for controlling the pear psyllid Cacopsylla pyri (L.) (Hemiptera: Psyllidae), which is harmful to pear trees. Studies involving Ankara pear-variety saplings were carried out in the Ankara province in three different pear orchards in two different locations in 2012. In the first stage of the study, experiments were conducted using visual yellow sticky traps to determine trap activity in the pear orchard. Afterward, mass trapping studies were carried out with the number of traps determined to be most effective in two different orchards. At the end of the study, it was observed that the yellow sticky traps had demonstrated a very high ability to attract C. pyri adults, but were insufficient to suppress the pest as time progressed. As a result, it was concluded that the use of yellow sticky traps alone in the control of C. pyri would not be sufficient. However, it has been concluded that the traps can be used as a monitor in the early spring period when overwintered C. pyri adults are present and the beneficial population is inactive.

Investigating the Relationship Between Physical Education Teachers' Perceptions, Technological Knowledge and Classroom Management Profiles

Overcoming the technology barrier is critical to integrating technology and education. Emerging and changing technologies are rapidly impacting individuals' daily lives as well as their educational lives. The concept of technostress seems to be associated with technological pedagogical field knowledge and classroom management profiles. This study also aims to determine if there is a relationship between PE and physical education teachers' technostress levels, technological pedagogical knowledge, and classroom management profiles. 275 PE and physical education teachers working in Ankara province participated in the study. Data collection was done using the scale to determine teachers' technostres level, technological-pedagogical knowledge and class management profile. The levels of technostres and technological-pedagogical knowledge did not differ significantly by gender, educational status, sport type, place of graduation, age, professional seniority, and time of technology use of physical education teachers. When examining classroom management profiles, there were differences by gender, educational status, athletic department, and age group, but no significant differences between place of graduation, professional seniority, and time of technology use. When examining the class management profiles by gender variable, it was found that female teachers are on the peripatetic and ignorant profile compared to males, by educational level of graduates and in the scatter profile, those who are in the athletic department in the individual sports do not match those in the team sports department in the profile, and in the age group of 24-34 years old were highly rated by the class management profiles in the 35-44 years old category. As a result, it was found that there is an excellent level of significant relationship between the perception of technostars and class management profiles of physical education teachers, in a negative way, while there is a non-significant relationship between Tpba and technostars, with class management and Tpba being positive.

Predominance and first complete genomic characterization of canine parvovirus 2b in Turkey.

Viral enteritis is a significant threat to domestic dogs. The two primary pathogens that cause viral enteritis in dogs are canine coronavirus (CCoV) and canine parvovirus (CPV). In this study, we investigated the occurrence of CPV-2, CCoV, and canine circovirus coinfection by characterizing circulating subtypes of CPV-2 in faecal samples from symptomatic dogs admitted to veterinary clinics located in Ankara, Elazığ, Kayseri, and Kocaeli provinces of Turkey, between 2019 and 2022. Virus detection by PCR and RT-PCR revealed that CPV-2 was present in 48 (77.4%) samples, and no other agents were detected. Based on the occurrence of the codon GAT at positions 1276 to 1278 (coding for aspartate at residue 426) of VP2, all CPV-2 isolates were confirmed to be of the CPV-2b subtype. The complete genome sequences of two CPV-2b isolates showed a high degree of similarity to and phylogenetic clustering with Australian and East Asian strains/isolates. The predominant CPV strain circulating in the three different regions of Turkey was found to be a CPV-2b strain containing the amino acid substitutions at Y324I and T440A, which commonly contribute to immune escape. This is the first report of complete genomic analysis of CPV-2 isolates circulating in symptomatic domestic dogs in Turkey. The evolution of CPV-2 has raised questions about the efficacy of current vaccination regimes and highlights the importance of monitoring the emergence and spread of new CPV-2 variants.Supplementary InformationThe online version contains supplementary material available at 10.1007/s00705-022-05509-4.

The Mediating Role of Normative Commitment and the Moderating Role of Organisational Justice on the Influence of Career Development on Job Engagement

An organisation's efficiency and effectiveness can be viewed as depending on the qualification of its employees. Organisational support and career development are among the factors that enable organisations to employ and retain qualified people. This study, which was conducted within the context of a social exchange, investigates the effect of career development on job engagement. As a result of the literature research, it has been determined that career development has a positive effect on job engagement, and it is further considered that normative commitment might have a mediating effect and organisational justice might have a moderating role in this relationship. The data was collected from 234 academics from four foundation universities in the Ankara and Mersin provinces of Turkey. The collected data were analysed using SPSS and AMOS package programs and the R and Python programming languages. The analyses demonstrate that there is a positive causal relationship between career development and job engagement, while normative commitment has a partial mediating role in this relationship, and organisational justice does not have a moderator role.

Determinação dos fatores que afetam o lucro por métodos quantitativos em empresas de frangos de carne

ABSTRACT This study was carried out to demonstrate how a regression model can be used as a decision support tool in the poultry sector, using variables that affect profit, within the scope of broiler enterprises that are engaged in contract production depending on broiler integrations. Enterprises included in the study were selected from Bolu, Sakarya and Ankara provinces those have the 24% of the rearing flocks and the integrations in Turkey. The 68 out of 9872 broiler enterprises existing in Turkey in 2017 were included in the study by random sampling method. The regression model obtained because of this study allows producers and institutions providing consultancy services in the broiler sector to monitor the marginal effect of variables that affect profit. As a result, when price and cost factors change under different risk conditions, the research model can be used as a decision support tool.

Durum Wheat Production Structure and Variety Preferences of Producers in Ankara Province

Bu çalışmanın amacı; uzun yıllardan beri Türkiye’nin önemli makarnalık buğday üretim alanlarına sahip olan Ankara ilinde, makarnalık buğday üretimi yapan tarım işletmelerinin üretim yapısının ve üreticilerin çeşit tercihlerinin incelenmesidir. Ankara ilinde makarnalık buğday üreten üreticilerin, yıllar itibari ile makarnalık buğday ekim alanlarını ve üretimini azalttığı görülürken, bilinirlilik ve ekim alanı olarak Kızıltan-91 makarnalık buğday çeşidinin önde olduğu belirlenmiştir. Üreticilerin uzun süredir kullanmış olduğu, bölgeye adaptasyonuna ve verim istikrarına güvendikleri makarnalık buğday çeşitlerinden vazgeçmedikleri, yeni geliştirilen çeşitlere yönelmeyerek riskten kaçındıkları ve sertifikalı tohumluk kullanımı konusunda yenilikçi olmadıkları görülmektedir. İklim koşullarına bağlı olarak, üretilen makarnalık buğdayın kalitesini arttırmaya yönelik yetiştirme metotları konusunda eğitim verilmesine, yeni geliştirilen çeşitlerin tanıtım ve yayımı konusunda yürütülecek faaliyetlerin çoklu disiplinli olarak kamu, özel sektör, kooperatifler ve üniversiteler ile işbirliği içinde planlanarak uygulanmasına ihtiyaç duyulmaktadır.

Türkiye'de Kültür Bitkilerinde Istilacı Tür Nysius cymoides (Spinola, 1837) (Hemiptera: Heteroptera: Lygaeidae)’ın Yeni Konukçuları ve Yayılma Alanları

In this study the outbreak of the false chinch bug Nysius cymoides (Spinola, 1837) (Hemiptera: Heteroptera: Lygaeidae) was discussed in cultivated plants, in Adana, Adıyaman, Ankara, Aksaray, Çorum, Denizli, Diyarbakır, Elazığ, Erzincan, Eskişehir, Hatay, İstanbul, Karaman, Kastamonu, Kayseri, Konya, Manisa, Mardin, Mersin, Şanlıurfa, Şırnak, Tekirdağ, Tokat, Yalova and Yozgat provinces during summer of 2018-2019. The geographic location and climatic conditions of these provinces are very different. Therefore, studied pest can adapt to different climate conditions. In 2019, the massive presence of this pest caused several damage to crops such as lack of plant development, dead spots on the leaves even the death of plants. Pest outbreaks occur in drought and warm periods; they can be related to ground wastes and depend on the previous crop for other species of the same genus. Due to the highest host diversity, it can rapidly spread to new areas. A specific Integrated Pest Management (IPM) program is so suggested for the related pest.

The Styles of School Principals’ Using Power Sources and the Relationship between Principal Support and Citizenship Behaviour (Ankara Province Example)

This study examines the school principals' styles of using their power sources and the relationship between principal support and organizational citizenship behavior. The study was carried out according to the survey model. The study sample consists of 450 teachers working in public primary schools in the central districts of Ankara. The sample was determined by stratified sampling. We used Personal Information Form, Leader Power Source Scale, Perceived Principal Support Scale, and Organizational Citizenship Behavior Scale as data collection tools. In the analysis of the data, we performed percentage, arithmetic mean, Kolmogorov-Smirnov test, Pearson product moment correlation coefficient, regression analysis and path analysis. Based on the findings, there is a positive and significant relationship between primary school principals' use of power sources, principal support, and organizational citizenship behavior. It has been concluded that principal support plays a mediating role that has a predictive effect on organizational citizenship behavior, especially by predicting charisma, reward, and expertise power styles. Furthermore, we found that the variables that most affect teachers' organizational citizenship behaviors are charisma power, expert power, reward power, principal support, and legitimate power, respectively. Therefore, it can be listed among the suggestions that school principals should support teachers more, generally prefer charisma, expert, reward and legitimate power.

Evaluation of the Existence of a New Race of Bremia lactucae on Lettuce

Lettuce is one of the most consumed leafy vegetables in Turkey. The production of lettuce has been to get difficult due to infestation of cultivation areas with Bremia lactucae. This pathogen is genetically very variable. Pathogenic variation of B. lactucae has not been studied yet in Turkey. The objective of this study was to monitore the races of B. lactucae in the two geographic regions of Turkey. During the lettuce growing season in May and October 2018, totally 72 diseased leaf samples containing B. lactucae sporangia were collected from the fields of Bartın and Ankara provinces. From these samples 6 isolates were obtained. After a multiplication procedure, in which the susceptible lettuce cultivar 'Green Towers' was used, the B. lactucae sporangia were inoculated in differentiating lettuce cultivars. The response of the lettuce seedlings to pathogen was evaluated on the 7, 11 and 14 days after inoculation. The qualitative method was used for the assessment of infected seedlings. Sextet codes of Ankara and Bartın isolates were found as 44-00-01 and 13-03-04 respectively. The sextet codes of Turkish isolates did not match any of the present 37 races of B. lactucae. This result suggests that our isolates may be new races or pathotypes.
