Published: March 2024

Background: Vascular endothelial growth factor (VEGF) signaling pathway plays an important role in the pathogenesis of seizure. The oxidant/antioxidant factors and miRNA expression in the brain are differentially regulated in seizure. Objectives: We aim to investigate the potential mechanism of action for the recombinant human VEGF (rhVEGF) in mice with maximal electroshock (MES)-induced seizure. Materials & Methods: A total of 40 male mice (weight: 20-25 g) were treated intraperitoneally with normal saline, or rhVEGF (50, 100, and 150 µg/kg, daily for 4 consecutive days). One hour after the last injection, seizures were induced in each animal by MES. The latency for the onset of the first clonus and the duration of hind limb extension (HLE) were recorded. The levels of nitric oxide (NO), total antioxidant capacity (TAC), and micoRNA-142-5p expression were determined in the hippocampus of mice. Blood-brain barrier (BBB) permeability was also estimated by Evans blue dye extravasation method. Results: The administration of rhVEGF at all doses significantly reduced the HLE duration. However, latency for the seizure onset increased after administration of 50 and 150 μg/kg rhVEGF and decreased after administration of 100 μg/kg rhVEGF. In the brain, the NO level decreased, while TAC level and microRNA-142-5p expression increased by rhVEGF treatment in mice with MES-induced seizure. Pretreatment with rhVEGF at doses of 100 and 150 μg/kg reversed the increase in BBB leakage induced by MES-induced seizures. Conclusion: The rhVEGF administration can prevent MES-induced seizures by regulating NO, TAC, and miR-142-5 expression levels in the hippocampus and reducing BBB leakage in mice.

Background and Aims Faulty movement patterns can lead to dysfunctional and uncoordinated mobility. A proper pattern can cause better movement. In fact, an efficient movement provides more energy for endurance and power with less effort and more mobility and agility. Many studies have reported the effect of feedback on improving faulty movement patterns as a risk factor for anterior cruciate ligament injury. This study aims to investigate whether feedback can affect the performance of people with abnormal lower extremity movement patterns or not. Methods This is a systematic review study. Related articles published from 2000 to 2020 were found by searching in international (Google Scholar, PubMed, ScienceDirect) and national (MagIran, IranDoc) databases using the keyword videotape augmented feedback, augmented feedback, feedback, jump-landing, immediate effect. Results Out of 10 reviewed studies, two were systematic review studies, one was a systematic meta-analysis study, and seven were interventional studies. In all studies, feedback methods had a positive effect on the biomechanics of the lower limb. Three studies examined the impact of feedback on performance, of which two studies stated that feedback caused a decrease in performance, while one study stated that feedback did not affect performance. Conclusion In many studies, feedback methods improved movement patterns, but further studies are needed to understand the effect of feedback on the performance of people with abnormal lower extremity movement patterns.

Background and Aims Patellofemoral pain syndrome (PFPS) is one of the common knee disorders, which can cause injuries or more complicated medical conditions. Proprioception is one of the factors that can be considered in the assessment of people with PFPS. The present study aims to compare the knee joint proprioception between female volleyball players with PFPS and healthy peers. Methods In this quasi-experimental study, 30 female athletes (16 with PFPS and 14 healthy) with a mean age of 24.33±3.39 years, height of 178.72±3.28 cm and weight of 67.76±8.04 kg participated. Knee joint proprioception was evaluated in two modes: weight-bearing (single-leg squat) and non-weight-bearing (knee extension). Kinematic data were recorded by eight motion capture cameras (Vicon, UK) at a frequency of 1000 HZ. Statistical analysis was done in SPSS software, version 26 using independent t-test. The significant level was set at 0.05. Results Findings showed that the error of reconstruction angles in weight-bearing (P=0.001) and non-weight-bearing (P=0.003) conditions was significantly different between the two groups. Conclusion The knee joint proprioception is weaker in female volleyball players with PFPS than in healthy peers, which can lead to more injuries. it is recommended to strengthen the proprioception in athletes with PFPS during treatment and rehabilitation, and more accurate tests should be designed to evaluate it.

Background and Aims A sedentary lifestyle can lead to cardiovascular diseases such as atherosclerosis. Despite the use of therapeutic interventions such as angioplasty in patients with atherosclerosis, the recurrence of stenosis is possible. Rehabilitation exercises can improve the function and structure of blood vessels by improving the biomechanics of the blood flow. In this study, we aim to assess the effect of eight weeks of aerobic exercise on selected blood biomechanical variables in the bilateral femoral artery of middle-aged men up to seven days after coronary angioplasty. Methods In this quasi-experimental study, participants were 30 men with coronary angioplasty aged 45-60 years, referred to the cardiac rehabilitation clinic of Tehran Heart Hospital. They were assigned to two exercise and control groups. Their systolic and diastolic blood velocity, pressure, and intensity were first measured. The aerobic exercise program was then performed according to the American College of Sports Medicine instructions. Analysis of covariance, paired t-test, or Wilcoxon test were used based on their results. The significance level was set at 0.05. Results The resting heart rate and systolic and diastolic blood pressures were at the same level in both groups, but the maximum heart rate of the control group was lower. The results showed no significant difference between two groups in any blood variables. Conclusion The effect of aerobic exercise was not confirmed in this study, may be due to heart disease or structural changes in the arteries (increased arterial stiffness and decreased arterial elasticity, especially in peripheral arteries). To increase the effect of rehabilitation exercises on peripheral arteries rather than central arteries, more intensity and duration of exercises are recommended to achieve the desired result.

Background and Aims Decreased muscle strength due to aging can lead to neuromuscular disorders, increased risk of falling, decreased function in daily activities, and reduced independence in the elderly. The present study aims to investigate the effect of eight weeks of TRX suspension training on lower limb muscle strength, balance, mobility, and fear of falling in older men. Methods This is a quasi-experimental. Participants were 30 elderly men with a mean age of 67.9±4.3 years who were assigned into two groups of TRX (n=16) and control (n=14). In the pre-test phase, lower limb strength was measured by the 30-second chair stand test, functional balance by the Berg balance scale, functional mobility by the timed up & go test, and fear of falling by the falls efficacy scale -international. Then, the TRX group performed the functional training for eight weeks, three sessions per week, each for about one hour. After performing the exercises, post-test assessments were performed in two groups. To compare the groups, the analysis of covariance and Bonferroni post hoc test were used in SPSS software, version 19. The significance level was set at 0.05. Results The TRX functional training significantly improved lower limb strength, balance, and functional mobility of the elderly (P≤0.001); however, it had no significant effect on their fear of falling (P>0.05). Conclusion Given the positive effects of TRX functional training on lower limb strength, functional balance, and mobility of elderly men, it seems that this suspension training can be used to improve lower limb muscle strength, functional balance, and mobility of older men.

Background and Aims The quality of life of hemodialysis patients who are in the final stages of renal failure is affected by various factors. Balance, as an important factor in physical ability, plays an important role in the physical and daily activities of people, including hemodialysis patients. Exercise and physical activity in these patients can reduce the symptoms of uremic syndrome, increase hemodialysis quality, and reduce mortality in these patients. This study aims to investigate the improvement of balance, quality of life, and satisfaction with life of hemodialysis patients after 8 weeks of combined exercises. Methods In this study, 24 patients with hemodialysis aged 40-60 years in Urmia, Iran participated voluntarily and were randomly divided into two groups of control (n=12) and exercise (n=12). Their quality of life (by 26-item World Health Organization quality of life questionnaire in four areas of physical health, psychological health, social relationships, and environmental health), satisfaction with life (by the satisfaction with life scale), static and dynamic balance (using the Prokin 212N device) were measured before and after 8 weeks of resistance-aerobic exercises in both groups. The control group had their normal daily activities during this period without any intervention. Results The combined exercise program significantly improved the static balance (P=0.001), dynamic balance (P=0.001), and quality of life (P=0.001 for physical, psychological, and environmental health; P=0.010 for social relationships) in the exercise group compared to the control group. In addition, a significant effect was found on the satisfaction with life in the exercise group (P=0.001). Conclusion The combined exercise program is effective in improving balance, satisfaction with life, and quality of life of hemodialysis patients. It is recommended to use these exercises to improve the balance, quality of life, and satisfaction with life of these patients.

Published: March 2024

Background and Aims There are different methods for quantifying the flexion-relaxation phenomenon (FRP). However, there is little standardization for them. This study aimes to evaluate the sensitivity of the ratio method in identifying the FRP in people with non-specific low back pain (LBP) and healthy people. Methods In this study,10 patients with nonspecific LBP and 10 healthy people participated voluntarily. They performed a trunk flexion with a straight knee. Each trunk flexion was done in four modes: (1) standing in the starting position, (2) trunk flexion at a fixed speed (using a metronome), (3) full flexion, and (4) trunk extension to the standing position. Each mode took 5 seconds and was performed 3 times. Then, the FRP was investigated using the ratio method as well as the visual inspection method. Results The sensitivity of all ratios in identifying the FRP in healthy people was 100%, except for the third ratio (the root mean square of EMG activity in a standing position divided by the root mean square in flexion mode), which was 60%. In the LBP group, the sensitivity of the first ratio was 70%; for the second ratio, it was 80%; for the third ratio, 40%; for the fourth ratio, 50%; for the fifth mode (the root mean square in extension mode divided by the root mean square in full flexion mode), 40%; and for the sixth mode, 50%. Conclusion All ratios (except for the second ratio) are valid for identifying the FRP in healthy people, but caution should be taken in using the ratio method for people with LBP; only the second ratio (maximum EMG activity in the extension mode divided by the average EMG activity in the full flexion mode) should be used for these individuals.

Published: March 2024

Background and Aims Dynamic knee valgus (DKV) is an abnormal pattern of movement or abnormal alignment of the lower limb that causes changes in lower limb function in the frontal plane and absorption of excessive reaction force by the knee ligaments during sports activities, which can increase the risk of anterior cruciate ligament injury. This study aims to compare the balance, strength, and range of motion (ROM) of hip and ankle joints in volleyball players with and without DKV. Methods This is a quasi-experimental and causal-comparative study. Participants were 60 volleyball players (30 with DKV and 30 without DKV). The tuck jump test was used to evaluate their DKV. The ROM of knee and ankle joints was measured using a goniometer, while the isometric strength of the hip and ankle muscles was determined using a hand dynamometer. Then static and dynamic balances were evaluated by the Stork test and the Y balance test, respectively. Independent t-test was used to compare the means of variables between the two groups in SPSS software, version 24. Results The results showed a significant difference in static balance (P=0.005), dynamic balance (P≤0.05), hip abduction strength (P=0.03), hip external rotation strength (P=0.01), and ROM of ankle dorsiflexion (P=0.03) between the two groups, where those without DKV performed better. The difference in other variables was not significant between the two groups. Conclusion The results indicate the importance of improving hip abduction and hip external rotation strength as well as the ROM of ankle dorsiflexion for reducing the DKV, which should be considered in designing training protocols.

Published: March 2024

Immunoglobulin G4-related disease (IgG4-RD) is an increasingly recognized fibroinflammatory condition with characteristic clinical, serological, and histopathological features. It might involve any organ in the body with a special predilection for lymph nodes, salivary glands, the pancreas, and the retroperitoneum. Due to the non-specific features of the disease and the capability of mimicking many other medical conditions, the diagnosis of IgG4-RD could be delayed. Herin, we describe a case of a middle-aged man who presented with obstructive jaundice due to a pancreatic mass. Further evaluation revealed multiple cervical and inguinal lymphadenopathy, bilateral wedge-shaped lesions in the kidneys and substantial thickening of the aortic wall that was suggestive of aortitis/periaortitis. A histopathological examination of an inguinal lymph node showed increased infiltration of nodal immunoglobulin G4 (IgG4) plasma cells (>30/high-power field) with a high serum IgG4 immunoglobulin level. Based on that, the patient was diagnosed with IgG4-RD, and he was successfully treated with pulse steroid therapy with complete resolution of his symptoms and the radiological and laboratory findings. IgG4-RD is a protean condition with a large spectrum of clinical manifestations that could mimic many other serious medical conditions. Early recognition and management of immunosuppression are vital for complete recovery.

Published: March 2024

Granular cell tumor (GCT) originating from the sellar and suprasellar regions, specifically from the neurohypophysis, is a rare neoplasm. Symptomatic GCT of the neurohypophysis is exceedingly rare, being <70 cases described so far. GCTs predominantly exhibit benign behavior, while the malignancy rate remains at 2%. Imaging is quite unspecific and diagnosis is difficult to establish preoperatively. Histopathology and immunohistochemistry serve as the definitive diagnostic approach for GCTs and help in distinguishing GCT from other pituitary tumors, including pituitary adenoma, pituicytoma, and spindle cell oncocytoma. These tumors are resistant to radiotherapy and chemotherapy, necessitating surgical resection as the primary treatment modality. Due to the potential absence of distinct tumor masses and local tissue infiltration by tumor cells, complete excision is crucial, with resection extent extending beyond areas of infiltration. Here, we present a rare case of GCT originating from the posterior pituitary in the suprasellar region. On immunohistochemistry, tumor cells expressed diffusely thyroid transcription factor-1, S-100 protein, and vimentin confirming the diagnosis of supra-sellar GCT. The reported case is noteworthy for the rarity of the clinicopathological entity.

Karar verme, yöneticinin en önemli fonksiyonu olarak bilinir. Karar vermede veriye dayalı bilimsel analiz yöntemlerinin kullanılması güvenilir sonuçlar sağlar. Böylece yöneticinin aldığı kararın daha rasyonel olması sağlanabilir. Tıpkı işletmeler gibi kentin yönetimi de aynı rasyonel bakış açısını gerektirir. Kent Konseyleri kamu, sivil toplum ve özel sektör paydaşlığı ile yönetişim prensibini benimseyen yapılandırmadır. Konseylerde alınan kararlar tavsiye niteliğinde olmakla birlikte burada alınan kararların yerel yöneticiler üzerinde yaptırımları bulunur. Kent Konseylerinde proje kararları verilirken toplumsal menfaatin ön planda tutulması beklenir çünkü yönetmek rasyonel olduğu kadar etik de olmalıdır. Bu çalışmada, yönetişim prensibinin en etkin uygulayıcısı olan Kent Konseylerinin proje seçim kararlarında göz önünde tuttukları kriterler değerlendirilmiştir. Dört farklı ilde (İstanbul, Bursa, Yalova ve Denizli) etkin çalışmalar sürdüren Kent Konseylerinin yürütme kurullarında görev alan altı yetkili (başkan, genel sekreter, proje yöneticisi), projelere ait altı kriteri değerlendirmişlerdir. Çok Kriterli Karar Verme tekniklerinden Analitik Hiyerarşi Süreci (AHS) kullanılarak uzman görüşleri sıralanmıştır. Uzmanların yaptığı özgün değerlendirmeler geometrik ortalama ile grup kararına evirilmiştir. Analiz sonucunda “proje ile ilgili siyasi beklentiler” kriterinin proje seçiminde en yüksek ağırlıkla ilk sırada yer aldığı görülmüştür. “Projenin sosyal etkisi” kriteri ise en düşük ağırlıkla son sırada yer almıştır. Ortaya çıkan bu sıralama Kent Konseylerinin tarafsızlık ilkesini sorgulatabilir.

Osmanlı Devleti, 19.yüzyılda Batı’daki topraklarının önemli bir bölümünü çeşitli savaşlarda kaybetmiştir. Yaşanan zorlu muharebeleri bünyesinde bulunduran 93 Harbi (1877-1878 Osmanlı-Rus Savaşı) bu savaşlardandır. Osmanlı’nın Batı’daki topraklarının bir bölümünü kaybettiği savaşta, Şıpka Geçidi önemli gelişmelere sahne olmuştur. Osmanlı ve Rus orduları Şıpka Muharebelerinde önemli kayıplar vermiştir. 93 Harbi ve içerisinde yaşanan Şıpka Muharebeleri, günümüzde bir kısmı yaşamaya devam eden çeşitli türkülere de konu oluşturmuştur. Anadolu ve Balkan coğrafyasında söylenmeye devam eden türkülerde savaşın sosyal boyutu, cephe gerisinde yaşanan hayat ve cepheye dair bilgiler yer almaktadır. Sözlü kültür ürünü olan türküler yoluyla bu bilgiler gelecek kuşaklara taşınmaya ve sözlü tarihe kaynak oluşturmaya devam etmektedir. Türkülerin sözlü tarih araştırmaları için kaynak oluşturması konusu, üzerinde çok fazla araştırma yapılmamış, araştırılmaya muhtaç bir konudur. Çalışmanın çıkış noktası, halk bilimi ve tarih disiplinlerinin, akademik açıdan üzerinde durmadığını tespit ettiğimiz Şıpka türkülerinin, kültürel ve sözlü tarih kaynağı olarak değerine vurgu yapılmasıdır. Makalede; Şıpka Muharebeleri’ni anlatan türkü metinlerinden hareketle, söz konusu türkülerin odak noktasını oluşturan tarihi olaylar ve bunların türkülere yansıması ele alınmaktadır. Ayrıca, bu çalışmada, literatürden elde edilen bilgi, metin ve görsel verilerden yararlanılarak Şıpka muharebelerinin gerçekleştiği fiziki, siyasi, sosyal koşullar tespit edilmekte; bu koşulların metinlerde hangi ifadelerle dile getirildiği ortaya konulmaktadır. Buna ek olarak, türkü metinlerinin yazılı tarih kaynaklarıyla uyumu, günümüzde canlı olarak varlığını koruma durumu, yapısal ve müzikal özelliklerinin tespiti amaçlanmaktadır.
The Causal Effects of Economic Policy Uncertainty on Changes in Exchange Rates and Volatility: Empirical Evidence from Türkiye
Authors: Çakar Recep
Published: March 2024

Applying a novel econometric method, nonparametric causality-in-quantiles approach, this paper investigates the causal effects of economic policy uncertainty (EPU) on Turkish changes in exchange rates and volatility with the monthly data spanning from February 1998 to December 2019. This approach of gives an opportunity to investigate the (non)causality in the θ-th quantile only in mean (first moment,i.e., m=1) or variance (second moment,i.e.,m=2) as well as the (non)causality in the mean and variance (m=1 and 2) successively. In sum, this approach calculates volatility by squaring returns. We use EPU indexes of the United States, Australia, European Union, Japan, Canada, and the United Kingdom and their currencies (USD, AUD, EUR, JPY, CAD, GBP, respectively) vis-à-vis Turkish Lira (TRY) and find that the EPUs of Australia, the European Union and Japan affect the returns of the AUD/TRY, EUR/TRY and JPY/TRY exchange rates, respectively. These results show that the EPU indices of these countries can give an idea about the returns and volatility of the relevant Turkish changes in exchange rates. The findings of this paper provide important implications for policymakers, investors, firms, exporters, and importers. Also, some studies can be carried out on the effects of the EPU index that will be created to Türkiye on the Turkish exchange rates or the other Turkish financial assets.

Bilgi her geçen gün önemini arttıran bir üretim faktörüdür. Bu faktörü elde edip geliştirebilmenin temeli ise inovasyon faaliyetlerine dayanmaktadır. Ekonomik büyümeyi sağlamak ülkelerin birincil hedefi olmakla birlikte artık bu hedefe ulaşmak sanayi yatırımları yerine bilgi ekonomisine dayalı üretimden geçmektedir. İktisat literatüründe teknolojiyi dışsal bir faktör olarak kabul eden dışsal büyüme modellerinin ülkeler arasındaki büyüme farklılıklarını açıklamada yetersiz kalması üzerine içsel büyüme teorileri olarak ifade edilen ve teknolojiyi içsel değişken olarak kabul eden teori literatürde yer almıştır. İlk olarak Schumpeter tarafından tanımlanan inovasyon, kullanılan teknolojilerin yerine yeni teknolojilerin geçmesi şeklinde tanımlanmış ve yaratıcı yıkım olarak ifade edilmiştir. Bu çalışmanın amacı, ekonomik büyümede önemli rol oynadığı düşünülen inovasyon ile ekonomik büyüme arasındaki nedensellik ilişkisini ortaya koyabilmektir. Literatürde yer alan ekonometrik çalışmalarda genellikle ekonomik büyüme ve inovasyon faaliyetleri arasında karşılıklı nedensellik ilişkisi tespit edilmiştir. Çalışmada bağımlı değişken olarak Gayri Safi Yurtiçi Hâsıla, bağımsız değişkenler olarak ise inovasyon faaliyetlerini temsilen Ar-Ge harcamaları, yüksek teknolojili ürün ihracatı ve patent sayıları kullanılmıştır. Ekonometrik analizde VAR modeli, Johansen Eşbütünleşme Testi ve Toda-Yamamoto nedensellik analizi yapılmıştır. Elde edilen sonuçlara göre; GSYİH ile patent sayıları arasında karşılıklı, Ar-Ge harcamalarından da ekonomik büyümeye doğru tek yönlü bir nedensellik ilişkisi bulunmaktadır. Türkiye’de Ar-Ge harcamalarının ekonomik büyümenin nedeni olarak bulunması bu harcamalarda sağlanacak artışların ekonomik büyümeyi arttıracağı sonucunu ortaya çıkarmaktadır.

Göç, nedenine göre farklılık gösterse de tarihsel süreçte hep var olan bir sosyal sorun olarak karşımıza çıkmaktadır. Bu çalışmada göç olgusu 2011 yılı sonrasında Suriye‟den kitlesel göç hareketiyle Türkiye‟ye gelen geçici koruma altındaki Suriyeli çocuklar odağında incelenmiştir. Geçici koruma altındaki Suriyeli çocukların eğitim, sağlık, çalışma hayatları ve sosyal yardımlardan yararlanma durumları dünya ve Türkiye verileri ile karşılaştırmıştır. Çalışma sonucunda Suriyeli çocukların her yıl eğitim-öğretim hizmetlerinden daha fazla yararlandığı ancak eğitim-öğretime katılım oranlarının Türkiye ortalamasının gerisinde olduğu belirlenmiştir. Suriyeli çocuklar psikolojik ve psikiyatrik sağlık hizmetlerine daha fazla ihtiyaç duymakla zor koşullarda ve ucuz iş gücü olarak çalışan Suriyeli çocukların yaş gruplarına göre çalışma oranları Türkiye ile benzer, dünya ile ise tam tersi bir özellik göstermektedir. Suriyelilerin genel olarak kişi başına düşen milli gelirleri dünya ve Türkiye‟nin oldukça altında olduğu dolayısıyla Suriyeli çocukların sosyoekonomik koşullar bakımından önemli yetersizliklere sahip olduğu anlaşılmıştır. Var olan bulgular geçici koruma altındaki Suriyeli çocukların eğitim, sağlık, çalışma hayatlarında ve sosyoekonomik koşullarında yetersizliklerin bulunduğunu göstermektedir. Dolayısıyla, var olan hizmet ve programların sürdürülebilirliğinin sağlanarak yeni hizmet ve programlar geliştirilmesi ihtiyacı söz konusudur.
Türkiye’de İnşaat Sektörü Sanayiyi Dışlıyor Mu? Hollanda Hastalığı Perspektifiyle Ampirik Çıkarımlar

Hollanda Hastalığı, ani zenginleşme kaynağına sahip olan bir ülkedeki üretim faktörlerinin tek bir sektöre yönelmesi sonucunda ortaya çıktığı öne sürülen ve diğer sektörlerin durgunlaşmasıyla ya da dışlanmasıyla sonuçlanan ekonomik süreci temsil eden bir kavramdır. Çalışmanın kaleme alınmasındaki temel motivasyon son yıllarda Türkiye’deki inşaat sektöründe yaşanan hızlı büyümenin sanayi sektörünü nasıl etkilediğini incelemek ve sanayinin inşaat sektörü bazlı Hollanda Hastalığına yakalanıp yakalanmadığını ortaya koymaktır. Bu amaçla Düzey 2 ölçeğinde yer alan 26 alt bölge için Türkiye İstatistik Kurumu’ndan elde edilen ve 2009-2017 yıllarını kapsayan veriler ışığında panel veri analiz yöntemi kullanılmıştır. Oluşturulan modelde sanayi istihdamı bağımlı değişkeni temsil ederken, bağımsız değişkenler dış ticaret hacmi, inşaat girişim sayısı, gayri safi yurtiçi hasıla (GSYİH) ve toplam istihdam şeklinde sıralanmaktadır. Analiz sonuçlarına göre inşaat girişimi sayısındaki her %1’lik artış sanayi istihdamını %0,36 artırmaktadır ki bu sonuç Türkiye’de inşaat sektörü kaynaklı Hollanda Hastalığının bulunmadığına işaret etmektedir. Bir diğer ifadeyle inşaat sektörü sanayiyi dışlamamakta, aksine çeşitli alanlarda fırsatlar sunmaktadır.

Tüketiciler, mağaza veya çevrimiçi alışveriş yoluyla ihtiyaçlarını ve isteklerini karşılamaktadır. İnternetin etkisiyle istek ve ihtiyaçları değişen tüketiciler, alışveriş yaptıkları ortama göre farklı ve değişken duygulara sahip olabilmektedir. Bazı tüketiciler mağazadan alışveriş yaptığında kendilerini daha mutlu hissedebileceği gibi, bazı tüketiciler ise çevrimiçi alışveriş esnasında kendilerini daha mutlu hissedebilmektedir. Pozitif duygulardan biri olan mutluluk, tüketicilerin alışveriş ortamını seçmesinde belirleyici bir unsur olabilmektedir. Çalışmanın temel amacı, çevrimiçi ve mağaza alışverişinden hangisinin tüketiciyi daha fazla mutlu ettiğini belirlemektir. Aynı zamanda, tüketicilerin kişiliklerinin yaşam memnuniyetine; yaşam memnuniyetlerinin öznel iyi oluşlarına ve mutluluklarına; alışverişten iyi oluşlarının yaşam memnuniyetlerine ve mutluluklarına etkisinin saptanması amaçlanmıştır. Bu amacı gerçekleştirmek amacıyla, Mersin ilinde yaşayan 400 tüketici ile çevrimiçi anket yöntemi kullanılmıştır. Elde edilen verilere bağımsız örneklem t-testi ve regresyon analizleri uygulanmıştır. Tüketicilerin pozitif kişilik özelliklerinin, çevrimiçi alışveriş yapan tüketicilerin yaşam memnuniyetlerini olumlu yönde etkilediği sonucuna ulaşılmıştır. Çevrimiçi alışveriş yapan tüketicilerin alışverişten iyi oluşlarının, yaşam memnuniyetlerini ve mutluluklarını pozitif yönde etkilediği, yaşam memnuniyetlerinin de öznel iyi oluşlarını ve mutluluklarını pozitif yönde etkilediği saptanmıştır.

Karavan turizmi sahip olduğu seyahat/konaklama şekli ve turist yapısı gibi unsurlarıyla diğer turizm türleri arasından sıyrılan özel bir turizm çeşididir. Bu çalışma, en temelde bu özel turizm türünün hitap ettiği turist kitlesini anlamaya yönelik olarak gerçekleştirilmiştir. Nitel araştırma yönteminin benimsendiği çalışmada, olgubilim araştırma deseninden yararlanılmıştır. Bunun için 11 soruluk bir mülakat formu hazırlanmış ve Sapanca’da gerçekleştirilen karavancılık festivaline katılan karavan turistlerinden olasılıklı olmayan örnekleme yöntemlerinden gelişigüzel örnekleme yoluyla 21 kişi seçilerek örnekleme dâhil edilmiştir. Elde edilen veriler içerik analizi tekniği ile kodlara ayrılmış, ulaşılan kodlardan kategoriler oluşturulmuş ve daha sonra genel temalara ulaşılmıştır. Sonuç olarak katılımcıların karavanla seyahat motivasyonlarına yönelik literatürle paralellik gösteren bulgulara erişilmiştir. Elde edilen bulgulara göre, karavan turistlerini seyahate iten faktörlerden “özgürlük” temasının çok ağır bastığı ve bunun yanında karavanın bir “keyif/tutku” ile “sosyalleşme” alanı olarak görüldüğü tespit edilmiştir. Yine karavanla seyahat motivasyonlarına ilişkin çeken faktörlere bakıldığında, katılımcıların ‘‘yeşil alanlar’’ ve ‘‘deniz/göl’’ kenarı gibi çekicilikler ile ‘‘istenen herhangi bir yere gidebilme’’ ve ‘‘güvenlik olanakları’’ temalarını ön plana çıkardıkları görülmüştür. Ayrıca karavan turistlerinin karavanla seyahati bir konaklamadan çok “yolda olma” arzusu olarak gördükleri bu çalışmada tespit edilen diğer bir unsurdur. Öte yandan çalışmada karavan turistlerinin tatil deneyimleri, tercihleri ve kişisel özelliklerine ilişkin anlamlı bulgulara erişilmiştir. Karavancıların yaşadıkları sorunlara ilişkin en çok ifade ettiği problemler ise tesis-altyapı yetersizliği, çöp sorunu ve güvenlik endişesi gibi sorunlardır.
