Special divisors on real trigonal curves
No full textIn this paper we examine the topology of Brill-Noether varieties associated to real trigonal curves. More precisely, we aim to count the connected components of the real locus of the varieties parametrizing linear systems of degree and dimension at least . We do this count when the relations are satisfied, where is the Maroni invariant and is the genus of the curve

No full textTailoring polysaccharide-based aerogels for potential food applications: Structural and hydration characterization by NMR relaxometry and diffusometry
No full textPolysaccharide-based aerogels are promising candidates for food-related applications due to their high surface area, adjustable porosity, biocompatibility, and biodegradability. The present study investigated chitosan, sodium alginate, and xanthan gum aerogels obtained by supercritical CO2 drying. Each polysaccharide exhibited unique structural and physicochemical behavior depending on polymer concentration, which influenced the final aerogel properties such as bulk density, pore size, surface area, and water absorption. NMR relaxometry and diffusometry were employed for a detailed characterization of pore structure, hydration behavior, and molecular mobility. Results revealed that, in contrast to alginate aerogels, lower polymer concentrations in chitosan led to more open networks with larger pores and higher surface areas, making them more suitable for applications such as filtration, adsorption, or active compound delivery. On the other hand, xanthan gum aerogels formed denser, more crosslinked structures, yielding high water absorption rate suitable for controlled release or encapsulation purposes. A hybrid chitosan/alginate aerogel successfully combined the advantageous properties of both components, resulting in low-density materials with enhanced porosity and mechanical integrity. The difference in aerogel structures obtained by different polysaccharides highlights the possibility of tailoring aerogel properties for specific food applications, from active packaging to edible carriers or moisture regulators. Given the need for safer, biodegradable, and versatile materials in the food industry, this study highlights the importance of designing aerogels based on the material type and offers a practical guide for producing them using scalable and safe methods

No full textTÜRKİYE'DE ÇEVRECİ DAVRANIŞLAR: BİR ÖLÇEK GELİŞTİRME ÇALIŞMASI
No full textGeçtiğimiz yıllardaki küresel sıcaklık artışı, orman yangınları ve kuraklıklar, insanların çevreyi korumak için harekete geçmemeleri halinde neler olabileceğinin bir göstergesi niteliğindedir. Gezegeni kurtarmada insan eylemlerinin önemini göz önünde bulundurarak, bu çalışmada, Avrupa'nın çevresel olarak en çok kirlenen ülkelerinden biri olan Türkiye'de çevreci davranışları ölçmek için kültüre özgü bir araç geliştirdik. Pilot çalışmada, çevre psikolojisi konusunda uzman kişilerle birlikte 52 maddelik bir havuz oluşturduk. Daha sonra, Türkiye Çevreci Davranış Ölçeğini geliştirmek ve psikometrik özelliklerini test etmek amacıyla iki çalışma yürüttük. Birinci çalışmada, ölçeğin faktör yapısı üniversite öğrencilerinden oluşan bir örneklem üzerinde inceledik (N = 454). Açımlayıcı faktör analizleri sonucunda toplam varyansın %60.03%'ünü açıklayan, 4 faktörlü 17 maddelik bir yapı elde ettik. Faktörler çevre okuryazarlığı (5 madde), atıkların azaltılması (5 madde), çevreye duyarlı tüketim (5 madde) ve kolektif eylem (2 madde) olarak belirlendi. Bulgulara göre, ölçeğin iç tutarlılığı psikometrik olarak sağlamdır ve uyum geçerliliği Çevresel Tutum Ölçeği ve Yeni Çevresel Paradigma Ölçeği ile pozitif korelasyonlarla desteklenmektedir. İkinci çalışmada, ölçeğin yapı geçerliliğini doğrulayıcı faktör analizi ile test ettik (N = 449) ve yapının verilerle kabul edilebilir bir uyum gösterdiği sonucuna vardık. Bulgular ölçeğin Türkiye bağlamında çevreci davranışları değerlendirmek için güvenilir ve geçerli bir araç olduğunu göstererek, gelecekteki araştırmalar ve çevre politikası geliştirme için değerli bilgiler sunmaktadır.The increase in the global temperature, wildres, and droughts that occurred in the past decades have presented a preview of what would happen if people do not start taking action to protect the environment. Considering the importance of human actions to save the planet, we developed a culture-specic tool to measure pro-environmental behaviors in Türkiye, one of the most polluted countries in Europe. In a pilot study, we created a pool of 52 items with subject matter experts on environmental psychology. Then, we conducted two studies to develop the Turkish Pro-Environmental Behavior Scale (TPEBS) and test its psychometric qualities. In Study 1, we examined the scale's factor structure on a sample of college students (N = 454). Exploratory factor analysis resulted in a 17-item, 4-factor structure explaining 60.03% % of the total variance. Factors were identied as environmental literacy (5 items), reducing waste (5 items), environmentally conscious consumption (5 items), and collective action (2 items). Findings indicated that the scale's internal consistency was sound, and the positive correlations with the Environmental Attitude Scale and the New Ecological Paradigm Scale supported the convergent validity. In Study 2, we tested the construct validity of the TPEBS through conrmatory factor analysis (N = 449), and the structure showed an acceptable t with the data. The tests of the internal consistency estimates further supported the reliability of the scale. These ndings suggest that the TPEBS is a reliable and valid tool to assess pro-environmental behaviors within the Turkish context, offering valuable insights for future research and environmental policy development
Resistance of the Parent: Insights from a Non-directive Play Therapy Case
No full textNon-directive play therapy is based on the idea that children have the capability and natural tendency to develop mature, necessary behavior in order to solve their problems, including inner conflicts. Such an orientation necessitates an accepting, respectful, and permissive therapeutic relationship with appropriate limits between the psychotherapist and the child. Also, the discourse of the parents toward the child has a strong impact to mediate both child’s position within the play, and therapeutic relationship. Although parents may consciously want the best for their children, their discourse about the therapeutic relationship or their children's problems may indicate an unconscious tendency to perpetuate their children's problems. The aim of this study is to demonstrate this proposition through a first session analysis of 7-year-old girl and her mother. As this single session demonstrates, the mother's discourse conveys messages that the child continuously needs psychological help, ultimately leading the child to refuse to play and resulting in dropout after this very first session. Lacan states that the child’s symptom functions in relation to what is symptomatic within the family. The position of the mother, therefore, can be considered as a resistance to the therapeutic process. By analyzing the session in depth -including the therapist’s own resistance- this study aims to highlight the possible resistance components within the discourse of the parents, that should also be addressed in the child’s psychotherapy process. Finally, recommendations will be provided, especially for novel play therapists, on balancing the child’s needs with parental resistance.</p
