Explicit Solutions for N-Dimensional Schrodinger Equations with Position-Dependent Mass

With the consideration of spherical symmetry for the potential and mass function, one-dimensional solutions of non-relativistic Schrodinger equations with spatially varying effective mass are successfully extended to arbitrary dimensions within the frame of recently developed elegant non-perturbative technique, where the BenDaniel-Duke effective Hamiltonian in one-dimension is assumed like the unperturbed piece, leading to well-known solutions, whereas the modification term due to possible use of other effective Hamiltonians in one-dimension and, together with, the corrections coming from the treatments in higher dimensions are considered as an additional term like the perturbation. Application of the model and its generalization for the completeness are discussed.Comment: 8 pages, no figure

Bound State Solutions of Klein-Gordon Equation with the Kratzer Potential

The relativistic problem of spinless particle subject to a Kratzer potential is analyzed. Bound state solutions for the s-wave are found by separating the Klein-Gordon equation in two parts, unlike the similar works in the literature, which provides one to see explicitly the relativistic contributions, if any, to the solution in the non-relativistic limit.Comment: 6 page

A search on Dirac equation

The solutions, in terms of orthogonal polynomials, of Dirac equation with analytically solvable potentials are investigated within a novel formalism by transforming the relativistic equation into a Schrodinger like one. Earlier results are discussed in a unified framework and certain solutions of a large class of potentials are given.Comment: 9 page

Recovery from work by playing video games

Integrating the dualistic model of passion in the recovery literature, the present study investigates how playing video games after work hours can facilitate recovery from work stress. We predicted that passion for gaming would relate to gaming more hours in the evening. Next, we hypothesized that playing video games in the evening would relate to (a) feeling recovered the next morning through psychological detachment and (b) feeling vigorous the next morning through mastery experiences while gaming. We further hypothesized that harmonious passion would strengthen, and obsessive passion would weaken the links between gaming hours and (a) psychological detachment and (b) mastery. In total, 65 employees filled in short questionnaires in the mornings and evenings of at least five workdays (total n = 502). Results of multilevel hierarchical regression analyses supported the proposed mediation model, indicating that playing video games indeed helps replenish energy resources during leisure time. Findings additionally showed that gaming also predicted feeling recovered in the morning through mastery experiences. Players with a harmonious passion may benefit more from playing video games; harmonious (but not obsessive) passion strengthened the relationship between gaming and mastery experiences.</p

Patterns of COVID-19-related headache: A cross-sectional study

Background: Headache is the most common COVID-19-related neurological symptom. We investigated the characteristics of COVID-19-related headache and their relationship with clinical severity in Kirs , ehir Province, Turkey. Methods: This cross-sectional study prospectively enrolled 226 COVID-19-positive patients who developed headache during acute infection. Demographic data, headache characteristics, and infection symptoms were recorded. The clinical severity of COVID-19 was documented in each participant. Result: New-onset COVID-19-related headaches lasting 4 days were reported in 164 patients (72.5 %); these were mostly bilaterally or localized to the forehead (58.4 %), pulsating (42.5 %), moderate to severe intensity (30.1 %), with a partial response to paracetamol (23.5 %). The other 62 patients (27.4 %) reported headaches before COVID-19. Their COVID-related headaches were fiery type (p = 0.025), of very severe intensity (p = 0.008), had a holocranial distribution (p = 0.004), and were less response to paracetamol (p = 0.003); the headaches were significantly more frequent after COVID-19 than before COVID-19. Older age, high body mass index, and low education level were significantly higher in the severe group (all p < 0.001). Female sex (p = 0.019) and being a healthcare worker (p < 0.001) were significantly more frequent in mild cases. Conclusions: Bilateral, prolonged, moderate to severe headaches that were analgesic resistant are more frequent in patients with COVID-19 infection. Further study should examine whether the headache characteristics distinguish COVID-19-related headaches from other types, particularly in asymptomatic subjects

Plasma biomarkers of brain injury in COVID-19 patients with neurological symptoms

Objective: Neurological symptoms (NS) were often reported in COVID-19 infection. We examined the plasma levels of glial fibrillary acidic protein (GFAP) and S100B together, as brain injury biomarkers, in relation to persistent NS in a cohort of patients with COVID-19 during the acute phase of the disease.Methods: A total of 20 healthy controls and 58 patients with confirmed COVID-19 were enrolled in this prospective study. Serum GFAP and S100B levels were measured by using enzymle linked immunoassay method from blood samples.Results: Serum GFAP levels were found to be significantly higher in the severe group than in the controls (p = 0.007). However, serum S100B levels were similar between control and disease groups (p > 0.05). No significant results for GFAP and S100B were obtained between the disease groups depending on whether the sampling time was below or above 5 days (p > 0.05). We did not find a correlation between serum GFAP and S100B levels and the presence of NS (p > 0.05). However, serum S100B levels were slightly higher in patients with multiple NS than in those with a single symptom (p = 0.044).Conclusions: Elevated GFAP was associated with disease severity but not with NS in COVID-19 patients. Whereas, high serum S100B was associated with the multipl NS in these patients. Our data suggest that GFAP and S100B may be of limited value currently in order to represent the neuronal damage, though serving a basis for the future work

BAT-TR: Turkish adaptation of Burnout Assessment Tool (BAT)

Avrupa ülkeleri arasında Türkiye, çalışanın bilişsel, duygusal ve fizyolojik fonksiyonlarını olumsuz etkileyen iş tükenmişliğinin oldukça yüksek olduğu ülkelerden birisidir. Bu anlamda Türkiye’de tükenmişlik düzeyinin doğru ölçülmesi ve müdahaleler geliştirilmesi büyük önem taşımaktadır. Bugüne kadar tükenmişliğin ölçümünde en çok kullanılan ölçeğin kavramsal, teknik ve uygulama anlamında önemli eksikliklerinin bulunduğunun tespit edilmesi üzerine bu eksiklikleri gideren yeni bir tükenmişlik ölçümü geliştirmek için Tükenmişlik Ölçeği Konsorsiyumu 26 ülkeden katılımcılarla Burnout Assessment Tool (BAT) Ölçeğini geliştirmiştir. Bu çalışmanın amacı BAT’ı Türkçeye uyarlamaktır. Bu amaçla üç çalışma yürütülmüştür. İlk çalışmada 295 katılımcılı bir çalışma ile ölçek tercümesi tamamlanmış ve faktör yapısı belirlenmiş, ikinci çalışmada 399 kişilik bir örneklem ile ölçeğin yapı geçerliği ve güvenirliği sınanmıştır. Üçüncü aşamada ise İş Talepleri-Kaynakları Modeli (İT-K, Demerouti ve ark., 2001) çerçevesinde 2778 katılımcılı bir çalışma ile ölçeğin nomolojik geçerliği test edilmiştir. Yapılan analizlerde BAT’ın Türkçe formunun (BAT-TR) dördü birincil ve ikisi ikincil olmak üzere altı faktörlü yapıya sahip olduğuna dair görgül destek bulunmuştur. Ayrıca, ölçekten elde edilen tükenmişlik puanlarının, İT-K (Demerouti ve ark., 2001) modeline uygun olarak iş talepleri tarafından pozitif olarak ve iş kaynakları tarafından negatif olarak yordandığı görülmüştür. BAT-TR’nin tükenmişliği ölçen Maslach Tükenmişlik Ölçeği (MTÖ) ve Oldenburg Tükenmişlik Ölçeği (OTÖ) ile pozitif, çalışmaya tutkunluk ile negatif ilişkisi olduğu bulunmuştur. Ayrıca, BAT-TR’nin, işle ilgili tutum ve davranışları MTÖ ve OTÖ’nün ötesinde açıklayarak artışlı geçerliğe sahip olduğu görülmüştür. Dolayısıyla, BAT-TR’nin dört kök faktörü ve iki ikincil semptomlu yapısı kullanılarak ölçeğin geçerliği ve güvenirliğine dair güçlü kanıtlar bulunmuştur. Çalışmanın literatüre katkıları ve kısıtlamaları tartışılmış, BAT-TR ölçeğinin Türkiye’deki tükenmişlik araştırmalarında kullanılabilecek bir ölçek olduğu önerilmiştir.Like many other European countries, Turkey has a high rate of employee burnout which negatively affects employees’ cognitive, emotional, and physiological functions. In this regard, accurate measurement of burnout and the development of interventions in Turkey are critical. It has been determined that the scale that has been used most frequently in the measurement of burnout has significant conceptual, technical, and application deficiencies. Thus, the Burnout Scale Consortium developed the Burnout Assesment Tool (BAT), with participants from 26 countries, to address these shortcomings. The purpose of this study is to adapt BAT to Turkish. Three studies were conducted for this purpose. First, the scale translation was completed, with the factorial structure being determined through a study of 295 participants. For the second study, the scale’s reliability and validity was tested with a study of 399 participants. For the third study, the scale’s nomological network validity was tested with a study of 2,778 participants, using the Job Demands-Resources Model (JD-R; Demerouti et al., 2001). As a result, the empirical evidence was found to support the six-factor structure, of which four are primary and two are secondary. Additionally, in line with the JD-R model (Demerouti et al., 2001), it was discovered that job demands positively predicted the scale, while job resources negatively predicted it. The BAT-TR was found to have a positive correlation with both the Maslach Burnout Inventory (MBI) and the Oldenburg Burnout Scale (OBS), but a negative correlation with work engagement. Additionally, it has been observed that, when compared to MBI and OBS, it has incremental validity for work-related attitudes and behaviors. Thus, the BAT-TR four core factors and two secondary symptoms provide strong evidence for the validity and reliability of the Turkish form. A discussion is presented with contributions to the literature and the study’s limitations, suggesting that the BAT-TR scale can be used in burnout research in Turkey
