A multi-criteria evaluation of cybersecurity incident management frameworks: integrating AHP, CMMI and SWOT
(Karyay Karadeniz Yayımcılık Ve Organizasyon Ticaret Limited Şirketi, 2026-01-15) Ağar, Hasan Çağlar; Çeliktaş, Barış
With the growing complexity and frequency of cybersecurity incidents, the selection of an appropriate incident management framework has emerged as a strategic imperative and a nontrivial decision-making problem for organizations operating across diverse sectors. This study presents a multi-dimensional evaluation of four globally recognized frameworks and standards—ISO 27035, NIST 800-61, ITIL v4, and PCI DSS—to determine their effectiveness across 10 rigorously selected key performance parameters. The initial stage of the study involved the identification of 20 preliminary parameters through expert input and literature synthesis. These were then evaluated by 70 cybersecurity professionals using a hybrid decision-making model combining Likert scale scoring, standard deviation filtering, CV score, Z-score normalization and the Analytic Hierarchy Process (AHP) for pairwise comparisons. The top 10 key parameters were derived based on calculated priority weights. To assess each framework, we applied the Capability Maturity Model Integration (CMMI) and visualized results via radar charts and heatmaps, offering comparative insights into operational maturity. Additionally, SWOT analysis was conducted to examine strategic positioning and identify opportunities for improvement. The outcomes not only provide a practical benchmarking guide for practitioners but also introduce a replicable, evidence-based methodology for academic and industry adoption. This work offers a novel and structured lens to evaluate incident management maturity, addressing the pressing need for strategic alignment, automation integration, and adaptive resilience in cybersecurity operations.
Psychometric properties of the emotional self-efficacy and prosocial behavior scales among Nigerian youths: a cross-cultural validation study
(Genç Bilge Yayıncılık, 2026-01-06) Akaiso, Emmanuel
This study examined the psychometric properties of the Emotional Self-Efficacy and Prosocial Behavior scales, originally developed in Italy, among Nigerian youths residing in urban and semi-urban contexts. A total of 108 participants completed measures assessing empathic ability, problem-solving, and interpersonal communication, alongside the Prosocial Tendencies Measure, which captures helping behaviors across anonymous, public, and emotionally salient situations. The findings demonstrated acceptable internal consistency across all scales, indicating satisfactory reliability within this cultural context. Descriptive analyses showed generally low levels of empathic and problem-solving selfefficacy, while interpersonal communication self-efficacy ranged from low to high. Correlational analyses revealed that empathic, problem-solving, and interpersonal communication self-efficacy were positively associated with prosocial behaviors, particularly in emotionally demanding contexts. Additionally, empathic and problemsolving self-efficacy were positively related to public prosocial actions. Overall, the findings provide preliminary evidence supporting the cross-cultural applicability of these instruments among Nigerian youths and highlight culturally relevant patterns in selfefficacy and prosocial functioning. The study contributes to the limited literature on psychological resources and prosocial development in Sub-Saharan Africa. Future research should employ larger and more diverse samples and explore the roles of resilience, personality traits, and value orientations in shaping prosocial behavior.
The mediating effect of self compassion in the relationship between job stress and burnout levels among employees
(SAGE Publications Inc., 2026-02-13) Günay, Ezgi; Ünver, Buket; Yılmaz, Simay
Objective: This study investigates the role of self-compassion as a mediator in the relationship between job stress and burnout among employees. While job stress is widely recognized as a critical factor leading to burnout, it has been suggested that self-compassion may be associated with a reduction in these negative effects. Method: Participants were 429 actively employed adults living in Turkey (50.6% female). The data were gathered using an online administration of standardized psychological scales, that is, Job Stressor Appraisal Scale, Copenhagen Burnout Scale, and Self-Compassion Scale. Four dimensions of work stress “Role and Workload, Role Inadequacy, Organizational Rules & Practices, and Subordinate Relations” are taken into consideration in the volumetric model. Path analysis with bootstrapping (5,000 resamples) was implemented using Mplus statistical software, with gender, economic condition, and way of working during COVID-19 as covariates. Findings: The model fit was acceptable in path analysis. Role and workload and role inadequacy had a significant direct impact on burnout. Self-compassion had a significant mediating impact on the relationship between role and workload and burnout and the relationship between role inadequacy and burnout. Conversely, for organizational rules and practices and subordinate relations, both direct and mediating effects were non-significant. The model accounted for 21% and 52% for variance in self-compassion and burnout, respectively. Conclusion: This study emphasises the mediating role of self-compassion in the effect of job stressors on burnout. These findings suggest that interventions promoting self-compassion in the workplace may be effective in reducing employee burnout.
Witnessing the end, supporting the living: A qualitative study of palliative caregiving in end-of-life patients in Türkiye
(Cambridge University Press, 2026-02-11) Sert Yurdakul, Selin; Erbay Erşen, Merve; Özel, Dilara
Objectives. Palliative care seeks to enhance the quality of life for individuals with serious illnesses and their families by addressing physical, emotional, and psychological needs. This phenomenological study examines the lived experiences of 8 caregivers in palliative care settings in Türkiye, focusing on the challenges they face, the coping mechanisms they employ, and their reflections on the caregiving role. Special emphasis is given to both psychological and somatic signs of stress, along with the possible advantages of body-oriented resilience techniques. Methods. Using a phenomenological qualitative design, semi-structured interviews were conducted with 8 caregivers providing care to relatives in a hospital-based palliative care unit. Data were collected between February and April 2023 and analyzed through conventional content analysis. Results. Four central themes emerged from inductive coding: harmony in healing, navigating difficulties, resilience in palliative care, and reflections on the finite. The findings reveal a dual reality: palliative caregivers derive meaning and satisfaction from compassionate connections, high-quality clinical care, and peer support, yet they also endure significant burdens, including emotional strain, physical exhaustion, disrupted daily routines, and shifting relational dynamics. Anticipatory grief and chronic stress responses were prevalent, frequently manifesting in both psychological and somatic forms (e.g., sleep disturbances, muscle tension, and autonomic arousal). Despite these challenges, palliative caregivers employed spiritual beliefs, peer interactions, and self-care routines as resilience strategies. Significance of results. The mind–body challenges identified in the study emphasize the need for interventions that focus on self-regulation and resilience, including body-oriented approaches that strengthen internal resources, regulate stress responses, and encourage adaptability. Incorporating such approaches into group-based settings may improve mutual support and enhance both individual and relational well-being. The study highlights the importance of comprehensive, caregiver-centered support systems to reduce burden and improve the overall quality of palliative care.
Bireylerin Covid-19’a dair tükenmişliklerinin algıladıkları Covid-19 riski, dünyaya ilişkin varsayımları ve ebeveyn biçimleri ile ilişkisi
(Türk Psikologlar Derneği, 2023-07-26) Erdem, Büşra; Ünver, Buket
Dünyaya İlişkin Varsayımları Ve Ebeveyn Biçimleri İle İlişkisi Tükenmişlik kavramı özellikle endüstri ve sağlık psikolojisi çatısı altında yer almakla birlikte Covid-19 pandemisi ile birlikte tükenmişlik ve salgın hastalıklar arasındaki ilişki klinik literatürde de dikkat çekmeye başlamıştır. Mevcut çalışma kapsamında bireylerin kitlesel bir dış faktör karşısında (Covid-19 pandemisi), süreç içerisinde yaşayacakları tükenmişlikleri ile olaya dönük algıladıkları risk, anlamsal dünyaları ve algılanan ebeveynlik biçimlerinin ilişkisini araştırmanın, olası pandemiler ya da paylaşılan toplumsal olaylar karşısında yaşanabilecek tükenmişlik olgusuna ve komorbidite tanıların ayrımına dair bütüncül bir bakış açısı sunması beklenmektedir. Bu doğrultuda gerçekleştirilen mevcut çalışmanın temel amacı bireylerin Covid-19’a dair tükenmişlikleri ile algıladıkları Covid-19 riski, dünyaya ilişkin varsayımları (DİV) ve algılanan ebeveynlik biçimlerinin ilişkisinin incelenmesidir. Aynı zamanda, sosyodemografik değişkenler ve Covid-19’a dair değişkenlerin Covid-19 tükenmişliği üzerindeki etkilerinin incelenmesi de araştırmanın diğer amacını oluşturmaktadır. Bu doğrultuda gerçekleştirilen çalışmanın örneklem grubunu 18-65 yaş aralığında yer alan 368 katılımcı (yaş ort. 33.85, SS=9.75; %58:4’ü kadın, %41.6’sı erkek) oluşturmaktadır. Çalışmanın veri toplama araçları Sosyodemografik Bilgi Formu, Koronavirüs Tükenmişlik Ölçeği (COVID-19-BS), Algılanan Covid-19 Risk Ölçeği (CPRS), Dünyaya İlişkin Varsayımlar Ölçeği (DİVÖ) ve Young Ebeveynlik Ölçeği (YEBÖ) şeklindedir. Yapılan analizlere göre kadın olanların, çocuk sahibi olmayanların, düşük eğitim düzeyi ve ekonomik durumu orta-alt ve orta-üste göre düşük ya da yüksek olanların ve anne babası ile yaşayanların Covid-19 tükenmişlik düzeylerinin daha yüksek olduğu görülmüştür. Öte yandan Covid-19’a dair değişkenlerden pozitif tanı alanların, fiziksel/sosyal izolasyon yaşayanların, iş yerinde ve pandemi öncesine göre daha yoğun çalışanların, Covid-19 nedeniyle yakın kaybı yaşayanların ve yakınları risk grubunda olanların Covid-19 tükenmişliklerinin daha yüksek olduğu bulgulanmıştır. Ayrıca yapılan korelasyon analizlerine göre Covid-19 tükenmişliği ile yaş arasında negatif yönde; algılanan Covid-19 riski ve bilişsel/duygusal alt boyutları ile pozitif yönde; DİV’in iyilik, adalet, şans ve kendilik değeri alt boyutları ve toplam DİV puanı ile negatif yönde; algılanan anne ebeveynlik biçimi ile pozitif yönde; algılanan baba ebeveynlik biçiminin ise küçümseyici/kusur bulucu, duygusal bakımdan yoksun bırakıcı, sömürücü/istismar edici ve kötümser/endişeli alt boyutları ile pozitif yönde anlamlı ilişkiler bulunmuştur. Son olarak hiyerarşik regresyon analizine dahil edilen tüm değişkenlerin toplam varyansın %40.8’ini anlamlı olarak [F= 8.690, p<.001] açıkladığı görülmüştür. Sonuçlar COVID 19 tükenmişliği üzerinde sosyodemografik ve Covid-19’a bağlı özelliklerin, algılanan ebeveynlik biçimlerinin, dünyaya ilişkin varsayımların, algılanan Covid19 risk algısının ve yordayıcı gücünün önemli olabileceğini düşündürmektedir. Mevcut bulgular ilgili literatür ışığında tartışılmış, çalışmanın sınırlılıklarına ve gelecek çalışmalar için önerilere yer verilmiştir.
The mediating role of difficulties in positive and negative emotion regulation in the relationship between early maladaptive schemas and cyber dating violence
(European Association for Behavioural and Cognitive Therapies (EABCT), 2023-10-07) Ünver, Buket; İnce, Elif Hazal
Introduction: Cyber dating violence includes all kinds of words, attitudes and behaviors that individuals use against their partners in order to harm the partner in the digital environment. In the present study, it was aimed to examine the mediating role of difficulties in positive emotion regulation and negative emotion regulation in the relationship between early maladaptive schemas and cyber dating violence. Method: The sample of the study consists of 298 individuals between the ages of 18-30 who are in a romantic relationship or have had a romantic relationship in the last 1 year. The data of the research was collected through Demographic Information Form, Cyber Dating Abuse Questionnaire, Young Schema Questionnaire-Short Form, Difficulty in Emotion Regulation Scale-Short Form and Multidimensional Measure of Difficulties in the Regulation of Positive Emotions. Results: Pearson Correlation Analysis was used to determine the relationship between early maladaptive schemas, difficulty in positive emotion regulation, negative emotion regulation and applied and exposed cyber dating violence. As a result of the statistical analyzes, significant relationships were found between four schema areas, disconnection&rejection, impaired autonomy and performance, other-directedness, overvigilance&inhibition, and the digital dating violence both applied and exposed. Mediation analysis revealed that difficulty in positive emotion regulation had a partial mediator role in digital dating violence applied and exposed to four schema domains. In addition, a partial mediating role of difficulty in regulating negative emotion was found between the areas of disconnection&rejection and others-directedness schema areas and the digital dating violence exposed. Dissusion: Individuals with an early life in an unhappy family develop schemas that cause them to turn to strategies such as fear, suppression and sabotage instead of feeling guilty for experiencing and enjoying positive emotions. At this point, the sabotage can be seen as the person being exposed to cyberbullying and/or being a cyberbully. The fact that digital dating violence seen in romantic relationships occurs especially through positive emotion regulation strategies reveals a need for how a positive emotion can be regulated especially in the adolescence and emerging adulthood group. Conclusion: The association of early maladaptive schemas and emotion regulation difficulties with digital dating violence suggests that clinicians may be effective in developing interventions for emotion regulation skills. In particular, in terms of regulation of positive emotions, impulse control, goal-oriented behavior, ability to activate emotional strategies, acceptance of emotions and regulation of targetoriented emotions and behaviors will be important therapeutic targets. Finally, awareness of cyber dating violence, cyberbullying and/or being a cyberbully that can be seen in adolescence and emerging adulthood group should be increased and people should be aware of their possible victimization.
The mediator role of schema modes in the relationship between parentification and co-dependency
(European Association for Behavioural and Cognitive Therapies (EABCT), 2023-10-07) Ünver, Buket; Önürme, Beyza; Bayram Kuzgun, Tubanur; Köse Karaca, Bahar; Kahveci, Ceyhun
Introduction: The disruption of the hierarchy between the parent and the child obscures the role of the child in the family. Parentification is characterized by the child taking emotional and/or instrumental responsibilities and caring for parents and siblings. Therefore, lead to significant difficulties in the child's development of a self, and these difficulties may be reflected in the child's romantic relationships in adulthood in the form of difficulties in thinking independently. This situation is conceptualized as codependency and is defined as excessive focus on others, assuming full responsibility, and low selfesteem. It is hoped that discovering the roles of schema modes, which are defined as emotional and behavioral states that emerge suddenly when people are hypersensitive, in these relationship styles will be a significant guide, especially in therapy sessions. Therefore, the main purpose of this study is to determine which schema modes mediate the relationship between parentification and co-dependence. Method: The research was conducted with 355 participants aged 18-69 years. The Sociodemographic Form, Parentification Inventory, Co-Dependency Assessment Scale, and Schema Mode Scale-Short Form were used in the study. Process Macro analysis Model 4 developed by Hayes (2013) was used to test the mediating role of schema modes between parentification and co-dependency. Results: According to the results of the analysis, the level of co-dependency is higher in women. Eight different mediator effect models were tested, including child modes, coping modes, parent modes, and healthy adult mode, between parent-focused parentification and sibling-focused parentification and codependency. The mediating role of the angry child mode, self-aggrandiser mode, and demanding parent mode was found between parent-focused parentification and co-dependency. In addition, the mediating role of the punitive and demanding parent mode was found between sibling-focused parentification and co-dependency. Discussion: It is noteworthy that the same mediating effect between both parent-focused and siblingfocused parentification and co-dependency is the demanding parent mode. The demanding parent mode, which prioritizes the needs of others, predicts co-dependency and shows the mode that should be studied first in treatment. The attention is drawn to the mediating variable between the punitive parenting mode, characterized by self-blaming aspects in individuals who assumed the responsibility of caring for their sibling during childhood, and perfectionism, which is co-dependency. Similarly, it is observed that the self-aggrandiser mode compensates for the emotional deprivation caused by parentification. These modes, which develop in root family interaction, mediate similar imbalances in adult roles. The prominence of the angry child and self-aggrandiser mode suggests that these individuals can be evaluated especially in terms of narcissism in studies and/or therapy sessions that examine the relationship between parentification and co-dependency. Conclusion: The schema modes come from the experiences of their root families and continue actively in the adulthood romantic relationships of individuals who take responsibilities that are not suitable for their developmental level in their childhood. It is thought that this study will enable individuals who experience parentification to define their unhealthy roles and explore their relational problems and will provide a new perspective on the predictor of childhood experiences on adulthood.

Bu analizlerden elde edilen bulgulara göre, ailesel beklentiler alt boyutu hariç, uyumsuz mükemmeliyetçilik alt boyutları ile tükenmişliğin her iki alt boyutu (duyarsızlaşma ve duygusal tükenme) arasında pozitif yönde korelasyon ilişkisi olduğu görülmektedir. Uyumlu mükemmeliyetçilik alt boyutlarından düzen, duygusal tükenme ile negatif yönde, kişisel standartlar alt boyutu ise duyarsızlaşma ile pozitif yönde korelasyon ilişkisine sahiptir. Ayrıca, bulgular psikolojik dayanıklılığın, uyumsuz mükemmeliyetçilik ve tükenmişlik arasındaki ilişkide kısmi aracılık etkisini ortaya koymaktadır. Sonuçlar değerlendirildiğinde, mükemmeliyetçi özelliklerin uyumlu ve uyumsuz mükemmeliyetçilik olmak üzere iki boyutta ele alınmasının, tükenmişlik kavramını anlamada daha detaylı veri sağlayacağı ve psikolojik dayanıklılık gibi tükenmişliğe tampon etkisi yaratabilecek kavramların ele alınmasının önemli olduğu düşünülmektedir.
Polyvagal theory and interoception-based interventions: approaches to strengthen mental resilience
(Psikiyatride Güncel Yaklaşımlar, 2026) Candaş Demir, Merve Umay; Hasateş, Mahmut Can
Humans survive by establishing healthy bonds, and these bonds provide emotional regulation, especially in the caregiver-infant relationship. Polyvagal Theory suggests that the autonomic nervous system supports survival by assessing environmental and internal safety signals. Interoception plays a crucial role in this process, referring to the ability to sense the body's internal states. In recent years, interoception-based therapies have proven effective in the treatment of psychopathologies, especially post-traumatic stress disorder. Interoceptive-based interventions, such as trauma-informed yoga, can improve individuals who do not respond to traditional treatment by enhancing emotional regulation and body awareness. The aim of this study is to examine the effects of humanto-human relationships on mental health in the digitalized world, within the framework of Polyvagal Theory. In particular, it emphasizes the important role of interoception in the bond we establish with ourselves and its significance in psychotherapy. The study proposes an approach that supports mental health by discussing the therapeutic effects of interoception and the role of these skills in improving communication between individuals. The study also offers suggestions on how interoception-based interventions can be utilized in clinical practice. Such therapies help individuals form healthier bonds with both themselves and others.

Theta and Beta1 frequency band values predict dyslexia classification
(John Wiley and Sons Ltd, 2025-12-29) Eroğlu, Günet; Harb, Mhd Raja Abou
Dyslexia, impacting children's reading skills, prompts families to seek cost-effective neurofeedback therapy solutions. Utilising machine learning, we identified predictive factors for dyslexia classification. Employing advanced techniques, we gathered 14-channel Quantitative Electroencephalography (QEEG) data from 200 participants, achieving 99.6% dyslexic classification accuracy through cross-validation. During validation, 48% of dyslexic children's sessions were consistently classified as normal, with a 95% confidence interval of 47.31 to 48.68. Focusing on individuals consistently diagnosed with dyslexia during therapy, we found that dyslexic individuals exhibited higher theta values and lower beta1 values compared to typically developing children. This study pioneers machine learning in predicting dyslexia classification factors, offering valuable insights for families considering neurofeedback therapy investment.

Oyunlaştırma, oyun bileşenlerinin oyun dışı alan ve içeriklere dahil edilerek kullanıcının katılımını ve motivasyonunu arttırmaya yönelik bir yaklaşımdır. İş, pazarlama, sağlık ve kişisel gelişim gibi pek çok alanda kullanılan oyunlaştırma, eğitimde öğrencileri motive etmek, öğrenmeyi daha eğlenceli ve ilgi çekici hale getirerek için kullanılmaktadır. Teknolojinin gelişmesi her alanda olduğu gibi eğitimde de geleneksel yöntemlere alternatif sistemlerin geliştirilmesine neden olmuştur. Son yıllarda akıllı telefon kullanımındaki yükselişle doğru orantılı olarak mobil uygulama kullanma sayısında da büyük bir artış görülmektedir. Mobil eğitim uygulamalarında da önemli artış olmuş; bu uygulamaların yaygınlaşmasıyla "mobil öğrenme" kavramı ortaya çıkmıştır. Mobil öğrenme, kullanıcıya mekan ve zamandan bağımsız, bilgiye ulaşma ve öğrenme olanağı sunmaktadır. Yapılan araştırmalara göre, mobil eğitime oyunlaştırma unsurları dahil edildiğinde, geleneksel eğitime ve herhangi bir mobil öğrenmeye göre daha etkili sonuçlar elde edilmektedir. Diğer yandan, bir eğitim uygulamasının başarılı olabilmesi sadece oyunlaştırmaya değil, içerik, kullanılabilirlik, işlevsellik, performans, arayüz tasarımı gibi pek çok değişkene bağlıdır. Bu çalışmada, oyunlaştırma kullanılan mobil eğitim uygulamalarında arayüz tasarımının oyunlaştırma tekniklerinin verimliliğine etkisi örnekler üzerinden incelenmiştir. Araştırma kapsamında, oyunlaştırma kullanılmış eğitim uygulamalarındaki arayüz tasarımının, kullanıcının öğrenim deneyimine ne kadar etki ettiğini ölçmek için "Quistudy" adlı uygulama tasarlanmıştır. Uygulamanın prototipi üzerinden “Sistem Kullanılabilirlik Ölçeği” ve “Kullanıcı Deneyimi Anketi” gerçekleştirilerek, arayüz tasarımının, oyunlaştırma yönteminin verimliliğine etkisinin olup olmadığı araştırılmıştır.
Deterrents affecting consumers’ organic product purchase
(International Journal of Economics, Commerce and Management, 2020-10) Yarman Ak, Anda; Teker, Dilek
Organic agriculture is becoming an important factor of the economy as years go by and as the awareness on the subject increases among consumers. Although the sector is very promising, the demand is still very low. The value added to be obtained by organic agriculture can be a strong factor of the economy, especially on local basis. Therefore consumers’ purchase behaviors must be examined thoroughly to figure out how the demand can be increased. This study is, hence, focused on the deterrents that prevent consumers to purchase organic foods. An online survey is employed to a sample size of 556 respondents out of 543 were selected based on answering all questionnaire. Two different question set is employed to buyers and nonbuyers to depict the reasons of buying and not buying organic food. This study demonstrates the deterrents for non buyers. The replies given to the hypothesis specific questions are tested by chi-square test. Regarding the outputs, the main deterrents for buying organic food is the lack of packaging and trust in the authenticity of the seller. However, cosmetic concerns are not examined as one of the deterrent for a buy decision. For elimination of these deterrents can convince the consumers to purchase organic foods, which in consequence increase the demand and cause value added for local economy.
Evolution of digital payment systems and a breakthrough
(Ms. M. B. Mondal, Ph.D., 2022-09-26) Teker, Suat; Teker, Dilek; Orman, Irmak
This analytical study examines the evolution of digital payment systems and the use by financial institutions and fintech companies in line with the changing user needs, along with the evolutionary developments in information technologies. It also makes a comparative analysis of digital payment platforms that are popularly used all over the world, e.g. PayPal, GooglePay, Wise. The introduction of the first ATM in 1967, the first contactless credit card payment in 1999, the introduction of blockchain in 2009, the emergence of GoogleWallet in 2011 and the introduction of Visa Click-topay in 2020 may be defined as the milestones of digital payment systems. Digital payment systems can be broadly classified as smart cards, online payments, mobile applications, blockchain transfers and biometric authentication. All payment systems in the world are generally shaped according to user needs. The exponential growth of e-commerce and the increasing influence of market regulators also contribute to shaping the future of payment systems. A decentralized monetary management is envisioned by the transition to a cashless economy, the emergence of new online financial institutions, and the adoption of blockchain and cryptocurrencies. It is concluded that the evolution of digital payment systems will expand convenience, refund, convergence, cross-border and time limitless transaction. With the increasing adoption of digital payment systems by all spenders, there is a clear transition towards a cashless economy. The current arguments in academic and professional platforms about the future of digital systems predict that by the 2050s, physical money will be completely out of circulation and these currencies will be replaced by virtual currencies that can easily be transferred over number of digital platforms.

However, agricultural production faces several constraints such as climate change, limited resources, and population growth, among others. These challenges require sustainable solutions to ensure food security, maintain ecological balance, and improve livelihoods. Agricultural technologies provide innovative approaches to overcome these challenges, enhancing productivity, efficiency, and profitability. This paper provides a discussion that agricultural technologies could be a viable and sustainable solution for agricultural production constraints.
Ebeveyn tutumları ve çocuk davranış problemleri arasındaki ilişkide ebeveyn mükemmeliyetçiliğinin aracı rolü
(Galenos Publishing House, 2025-11-11) İnce, Merve; Akçınar, Berna; Yılmaz, Simay
Amaç: Bu çalışma, annelerin mükemmeliyetçiliğinin, annelerin ebeveynlik stilleri ile çocukların içselleştirme ve dışsallaştırma davranış problemleri arasındaki ilişkide aracılık rolünü incelemeyi amaçlamaktadır. Gereç ve Yöntem: Örneklem, 3-6 yaş arası çocukları olan 271 anneden oluşmaktadır. Katılımcılardan sosyodemografik bilgi formu, Ebeveyn Tutum Ölçeği, Hacettepe Ruhsal Uyum Ölçeği ve Çok Boyutlu Mükemmeliyetçilik Ölçeğini doldurmaları istenmiş ve veriler çevrimiçi olarak toplanmıştır. Bulgular: Çalışmanın ana hipotezini test etmek için yapılan analiz bulgularına göre demokratik ebeveynlik, içselleştirme (b=-0,117, p<0,05) ve dışsallaştırma (b=-0,076, p<0,05) davranış problemlerini negatif yönde yordamıştır. Bu ilişkilerde annenin kendine yönelik mükemmeliyetçiliği (KYM) ve sosyal olarak belirlenen mükemmeliyetçilik (SBM) aracılık etmemiştir. Otoriter ebeveynlik, içselleştirme (b=0,046, p<0,05) ve dışsallaştırma (b=0,049, p<0,05) davranış problemleriyle pozitif yönde ilişkilendirilmiş ve bu problemler üzerindeki etkilerinde KYM ve SBM aracılık rolü üstlenmemiştir. Buna karşın, aşırı korumacı ve izin verici tutumlar bu davranış problemlerini anlamlı bir şekilde yordamamıştır. Ayrıca, annelerin KYM’nin, aşırı korumacı ve izin verici ebeveynlik tutumları ile içselleştirme ve dışsallaştırma davranış problemleri arasındaki ilişkide aracılık etkisi olmadığı bulunmuş; ancak SBM’nin aşırı koruyucu ebeveyn tutumu ile içselleştirme [b=0,017, standart hata (SH)=0,009, güven aralığı (GA): (0,003, 0,038)] ve dışsallaştırma [b=0,012, SH=0,007, GA: (0,001, 0,029)] davranış problemlerinde ve izin verici ebeveyn tutumu ile içselleştirme davranış problemi [b=0,013, SH=0,008, GA: (0,000, 0,033)] arasında aracılık etkisinde bulunduğu görülmüştür. Sonuç: Bu çalışma, ebeveynlik tutumları ve özelliklerinin çocukların ruh sağlığı üzerindeki önemli rolünü vurgulamakta, ebeveynlerin etkili ve olumlu ebeveynlik yaklaşımlarını benimsemeleri için pratik müdahalelerin gerekliliğini belirtmektedir.

This study examines the impact of supply chain management practices on the organization’s marketing and financial performance. We present the results of a survey conducted with 100 Pakistani fan manufacturing firms. Statistical analysis reveals that the industry struggles with information sharing and joint operations within the supply chain. PLS-SEM analysis of the survey data shows that supply chain performance is significantly correlated with organizational performance. Both customer and supplier relationship management have positive and significant effects on the performance of the supply chain and the organization. However, the impact of customer relationship management is stronger as its path coefficient is greater. Additionally, although internal supply chain management also impacts both supply chain and organization performance positively, the impact is slightly short of being statistically significant. This study contributes to the supply chain management literature by providing empirical evidence from an understudied manufacturing sector from a developing country.
