Portföy Analizinde Beklenen Getiri Sorunu: Markov Getiriler ve Basit Getirilerin Karşılaştırılması
Authors: ÇAM Salih
Published: August 2021

Ortalama varyans modeline göre optimal portföyler oluşturulurken yatırım araçlarının geçmiş değerlerinden yararlanarak hesaplanan birinci moment (getiri) ve ikinci moment (varyans) değerleri kullanılmaktadır. Amaç, belli bir getiri değerine bağlı olarak minimum riskli portföyler oluşturmak veya belli bir risk değerine bağlı olarak maksimum getiri elde etmektir. Fakat kullanılan risk ve beklenen getiri ölçütüne göre portföydeki hisse senetleri çeşitliliği ve hisse senedi ağırlıkları farklılık göstermektedir. Dolayısıyla doğru risk ve getiri ölçüsü kullanmak daha etkin portföyler oluşturmak için önemlidir. Bu çalışmada literatürde yaygın olarak kullanılan klasik getiri ölçüsü (geçmiş getirilerin beklenen değeri “Basit getiri”) ile Markov zincirleri modellerinden elde edilen getiriler karşılaştırılmış ve bu getirilerin portföy oluşturma üzerindeki etkileri incelenmiştir. Markov getirili modellerin basit getirili modellerden daha etkin portföyler oluşturduğu sonucuna ulaşılmıştır.
Socio-Economic Determinants of Tax Evasion: Evidence from the European Union
Authors: DAYIOĞLU ERUL Rana
Published: August 2021

The purpose of this study is to investigate the key determinants of tax evasion across countries. Accordingly, the relationship between socio-economic determinants and tax evasion is examined by using panel data analysis. Based on the data for the European Union, the results show that economic variables have generally stronger effects than non-economic variables on tax evasion. The findings indicate that the lower the level of sound money and the higher level of social capital, economic quality and rule of law, the lower is the level of tax evasion across countries. These results may lead policy makers to design the policies by understanding the main determinants of tax evasion internationally.

Published: August 2021

Aim: Prediabetes is known to be associated with increased cardiovascular diseases (CVD) risk and mortality. It has been reported that more than 70% of pre-diabetic patients develop Diabetes Mellitus (DM). In patients with acute myocardial infarction (AMI), diabetes increases a 2 to 4 fold risk of adverse cardiovascular events compared to non-diabetic patients. This morbidity-mortality relationship begins in the progression phase from normal glucose tolerance to diabetes. We evaluated the relationship between the presence of pre-diabetes by using hemoglobin A1c (HbA1c) values and CVD risk in patients presenting with newly diagnosed AMI.

Methods: This study was a retrospective, single-centre and we examined consecutive patients who underwent coronary angiography with a diagnosis of AMI at our hospital between March 2019 and September 2020. A total of 332 patients with AMI were enrolled; patients were divided into two groups according to their HbA1c levels: non-diabetic group (HbA1c

Published: August 2021

Aim: Kefir is a probiotic/prebiotic drink with an exotic flavor, which has been traditionally produced with fermented milk and kefir grains containing a mixture of bacteria and yeast. Cyclophosphamide (CPx), are generally limited due to numerous unwanted and severe acute toxic side-effects. For this purpose, the cell-protective effects of kefir, a natural probiotic known for its antitumor and antioxidant properties, on CPx-induced hemotoxicity and myelotoxicity were investigated.

Methods: Group 1 using as control. Group 2 were administered a single dose of 150mg/kg CPx while Group 3 and 5 were given 5 and 10mg/kg kefir. Group 4 and 6 were given 5 and 10mg/kg kefir+150mg/kg CPx. While kefir was administered to the rats for 12 days, CPx was administered as single-dose on the 12th day.

Results: The DPPH results show that kefir possesses high antioxidant activity. It was observed that the leukocytes, thrombocytes, erythrocytes, hemoglobin, hematocrit and bone marrow nucleated cell levels decreased in the group that was administered only CPx, and increased relatively in the groups that were administered CPx+kefir, drawing close to the control.

Conclusion: The results of the present study also showed that kefir demonstrated antioxidant and cytoprotective activity, protecting blood and bone marrow cells against CPx-induced damage.

Authors: DÖNMEZ Ramazan , ANDAÇOĞLU Oya
Published: August 2021

Objectives: We aimed to describe our technique and donor selection for donor hepatectomy, review our case series and report our complication rates and outcomes.

Materials and Methods: We retrospectively reviewed 41 consecutive donor hepatectomy cases between October 2019 and November 2020 at Yeditepe University, Istanbul, Turkey. Complications were graded according to Clavien-Dindo classification. All cases were performed via laparotomy.

Results: Out of 41 donor cases, 38 (92,6%) were right lobe, 2 (4,8%) were left lobe and 1 (2,4%) was left lateral segment donor hepatectomy. Follow up was 9 ±2,2 months (4-16 months). There were 8 (19,5%) complications and all were minor (grade 1 or 2). There were no grade 3 or higher complications. Three (7,3%) of our donors are heterozygous for factor 5 leiden mutation and 4 (9,7%) of our donors had heterozygous prothrombin mutation. Length of stay was average 6.4±1,4 days (range=5-12). Ten donors lost weight with a supervised diet and exercise program. There was one wound complication in this subset of patients.

Conclusions: We present our single center donor hepatectomy series with excellent results. We also describe successful weight loss for donors with Body Mass Index (BMI) >30. Donor safety is the most important component of living donor liver transplantation. As donor results continue to improve, living donor liver transplant (LDLT) will continue expand worldwide.

Authors: KAYA Ender , BARLAS Fatma
Published: August 2021

Aim: In Major Depressive Disorder (MDD) residual symptoms cause disability in the remission phase even if they are mild. This study investigated the correlation of residual depressive and residual subjective cognitive symptoms with social functioning in remitted MDD patients.
Methods: In the study, 51 patients who had been diagnosed with MDD before, were followed regularly and had been in remission for at least 6 months, were included. The socio-demographic data form, Beck Depression Inventory, Perceived Deficits Questionnaire-Depression, and Social Adaptation Self-evaluation Scale were applied to all participants. In the statistical analysis; descriptive analyses, Pearson’s Correlation Analysis and linear regression analysis were used.
Results: Residual depressive symptom severity showed a positive correlation with social functioning level, while residual subjective cognitive symptom severity had a negative correlation with social functioning level. In the linear regression analysis it was determined that residual depressive and subjective cognitive symptom scores were a predictor of social functioning.
Conclusion: In the study, it was determined that residual depressive and subjective cognitive symptoms encountered in MDD remission phase might affect social functioning negatively. Rapid and practical subjective cognitive tests can be used in identifying cognitive symptoms in MDD remission phase.

Published: August 2021

Aim: It is unknown whether there is an increase in the frequency of acquired respiratory tract infections (ARTIs) while the weight loss process continues after bariatric surgery (BS).
Methods: An observational case-crossover study of 366 patients underwent BS between September 2018 and September 2019 was performed. Prospectively recorded data of ARTI events in the first pre- and post-operative ARTI seasons were compared.
Results: Mean age was 36.4 ± 10.9 years and mean body mass index (BMI) was 44.1 ± 6.2 kg/m2. Mean change in BMI in an ARTI season was 13.2 ± 6.1 kg/m2. Among 366 patients, 180 (49.2%) were diagnosed with ARTI and the average numbers of ARTIs was 0.69 ± 0.85 in preoperative season. During the postoperative season, 134 (36.6%) patients were diagnosed with ARTI and the average numbers of ARTIs was 0.49 ± 0.76. Both period prevalence and average number of ARTIs in preoperative ARTI season was significantly higher than postoperative season (P = 0.001 for both). The change in BMI in an ARTI season was correlated with the postoperative period prevalence of ARTIs (r = 0.119, P = 0.022).
Conclusion: These findings showed that the period prevalence and incidence of ARTIs reduced after BS. However, the frequency of ARTIs was higher in patients with greater weight loss.

Authors: Oleksyn Khrystyna , Rozhko Mykola
Published: August 2021

Introduction. Under the concept of occlusion, we understand the harmony between the dental arches, TMJ and neuromuscular system (masticatory muscles). Occlusal contacts play an important role in ensuring physiological occlusion. Dental caries is one of the main reason of occlusal disorders. In economically developed countries, it affects 95-98% of the population. Carious process causes changes in location of occlusal contact points, which is the reason of atypical mandibular movements. As a consequence, tooth overload and occlusal trauma are observed. Aim. The purpose of our research is a prevention of occlusal disorders by the method of composite restoration of affected occlusal surfaces considering functional anatomy with father checking of occlusal relationships with the help of computerized system T-Scan Novus. Material and methods. For this we have chosen 90 first-/second-/third-year students of Ivano-Frankivsk National Medical University at the age of 17-20, who were the citizens of the regions with low level of fluoride. Half of them had carious lesion of first molars, another 45 students had first molars, which were restored without principle of occlusion. Treatment was carried out by methods of direct and indirect restoration of occlusal surfaces taking into account the functional anatomy. Results. The article contains the results of redistribution of occlusal contact in first molar with carious lesion (decrease in the occlusal load on the affected tooth, occurrence of overload on the tooth with larger area of chewing (occlusal surface) and restoration of first molar without taking into account the principles of functional anatomy (occurrence of occlusal interferences directly on it). Further restorations of chewing surfaces of first molars considering the occlusal determinants led to an even distribution of the occlusal force on the molars. Conclusions. The obtained results of our study demonstrate the effectiveness of created treatment and prevention complex.

The notion of ‘grammaticalization’ — the embedding of once non- (or less-) grammatical phenomena into the grammar of a language — has enjoyed broad acceptance over the past 30 years as a new paradigm for describing and accounting for linguistic change.  Despite its appeal, my contention is that there are some issues with ‘grammaticalization’ as it is conventionally described and discussed in the literature.  My goal here is to explore what some of those problems are and to focus on what grammaticalization has to offer as a methodology for studying language change.  Drawing on case studies from the history of English and the history of Greek, I reach a characterization of how much of grammatical change can legitimately be called “grammaticalization” and how much is something else. In this way, I work to achieve a sense of what grammaticalization is and what it is not.
From SPEAKING to SEMIOSIS
Authors: Pennycook Alastair
Published: August 2021

This paper explores the quest for an account of the ‘total linguistic fact’. Speech act theory, sociolinguistics, linguistic anthropology and social semiotics have all attempted, in various ways and at various times, to find a way to describe as much as possible that is going on around any speech event. While this search for the total linguistic fact will always be a chimerical goal, this paper proposes a framework based on the acronym SEMIOSIS as one way of grasping the complexity of what is at play, comprising social relations, emotional and sensorial engagement, mobility, Iterative activity, objects and assemblages, socio- and translingual practices, interactivity, and spatial repertoires. Looking at data from a small Bangladeshi-run store in Tokyo, the paper shows how bringing in this wider set of concerns at least allows for a more comprehensive account of sociolinguistic moments.

Authors: Narkevich L. V.
Published: August 2021

The article proposes an effective mechanism for managing the renewal of fixed assets of textile industry enterprises, taking into account the industry features of the production of digital textiles on the basis of an information and analytical platform.

The theoretical and methodological foundations of the system approach have been tested on the processes of managing the renewal of fixed assets and their financing in Public Joint Stock Company “Mogotex”. The innovation and investment project for the renovation of finishing production is based on the results of an analytical study, reasonable parameters and criteria, which makes it possible to create the framework of Industry 4.0 and the basis for industrial scientific and technological integration within the framework of the Eurasian Economic Union.

Исследована реология водных растворов полиакриловой кислоты, полиакриламида, поливинилового спирта, сополимера акриловой кислоты с акриламидом, a также смесeй водных растворов этих полимеров. В результате образования ассоциатов между функциональными группами уаказанных полимеров значительно повышается относительная вязкость их водных растворов. Установлено, что при температуре 95C в водных растворах полиакриламида и сополимера акриловой кислоты с акриламидом происходит интенсивное выделение аммиака с одновременным образованием полимера пространственной структуры.

The rheology of aqueous solutions of polyacrylic acid, polyacrylamide, polyvinyl alcohol, copolymer of acrylic acid with acrylamide, as well as mixtures of aqueous solutions of these polymers was investigated. As a result of the formation of associates between the functional groups of the polymers indicated, the relative viscosity of their aqueous solutions significantly increases. It was established that at a temperature of 95°C in aqueous solutions of polyacrylamide and a copolymer of acrylic acid and acrylamide, there is an intense release of ammonia with simultaneous formation of a polymer of spatial structure.
MAÍZ, AUTONOMÍA Y TERRITORIO
Authors: De Lara Oscar Arnulfo de la Torre
Published: August 2021

El maíz, uno de los cultivos más importantes para la humanidad, fue domesticado en Mesoamérica hace aproximadamente 10,000 años. En la actualidad sigue siendo el principal sustento de la población rural de México, además de ser un importante e insustituible componente en la dieta de su población urbana. Ahora bien, México no sólo es centro de origen del maíz, también es centro de su diversificación constante, siendo un ejemplo excepcional de la interacción histórica que la humanidad ha mantenido con la naturaleza. No obstante, esta forma de ser humanidad se ve gravemente amenazada, ante la pretensión de sembrar comercialmente maíz genéticamente modificado en campo mexicano. Por lo anterior existen actualmente procesos de lucha por la defensa del maíz y la defensa del territorio, articulados a la construcción de las autonomías en los hechos. A partir de estos procesos se hace una construcción de derechos humanos situada; desde un lugar de enunciación distinto al de la modernidad colonial, mediante el ejercicio de un conjunto de prácticas sociales, simbólicas, culturales e institucionales como reacción contra los excesos de poder que impiden a los seres humanos constituirse como sujetos ”“individuales o colectivos”“ de su propia historia.

Effect of Increasing Running Cadence on Peak Impact Force in an Outdoor Environment
Authors: Musgjerd Taylor , Anason Jacob , Rutherford Drew , Kernozek Thomas W
Published: August 2021

Background

An estimated 56% of recreational runners sustain a running-related injury related to the high impact forces in running. Increasing step frequency (cadence) while maintaining a consistent speed has been shown to be an effective way to lower impact forces which may reduce injury risk.

Purpose

To examine effects of increased cadence on peak impact force during running in an outdoor setting. It was hypothesized that as cadence increases, peak force would decrease.

Study Design

Repeated measures, quasi-experimental

Methods

Peak force and cadence measurements were collected from 15 recreational runners (8 females, 7 males) during two 2.4-mile outdoor runs. Peak force was measured using an insole-based load measuring device. Baseline session run was completed at participant’s naturally preferred cadence and cadence session run was completed at a cadence targeted to be 10% greater than baseline. Pace was monitored with a GPS watch. Cadence was cued by an auditory metronome and measured with both GPS watch and insoles. Repeated-measures ANOVA’s examined the differences in average peak force, GPS-reported cadence, and insole-reported cadence between mile 1 and mile 2, and across the two cadence conditions.

Results

Cadence differences of 7.3% were observed between baseline and cadence sessions (p<0.001). A concurrent decrease in average peak force of 5.6% was demonstrated during the cadence run (p<0.05). Average cadences measured by GPS watch and insoles were found to be the same at both baseline (p=0.096) and during cadence (p=0.352) sessions.

Conclusion

Increasing cadence by an average of 7% in an outdoor setting resulted in a decrease in peak force at two different time points during a 2.4-mile run. Furthermore, using a metronome for in-field cadence manipulation led to a change in cadence. This suggests that a metronome may be an effective tool to manipulate cadence for the purpose of decreasing peak impact force in an outdoor setting.

An Investigation of the Association between Transversus Abdominis Myofascial Structure and Activation with Age in Healthy Adults using Ultrasound Imaging
Authors: Gaudreault Nathaly , Benoît-Piau Justine , van Wingerden Jan Paul , Stecco Carla , Daigle Frédérique , Léonard Guillaume
Published: August 2021

Background

Because of their importance in core stability, training the deep abdominal muscles, fascial structures and particularly the transversus abdominis, is a key component of many sport and physical therapy programs. However, there are gaps in knowledge about age-related changes in the structure and activation capacity of these muscles.

Hypothesis/Purpose

This study investigated the association between deep abdominal muscles and fascial structures and transversus abdominis activation with age in healthy adults.

Study design

A cross-sectional study.

Methods

Eighty-six adults aged 18 to 77 participated in this study. An ultrasound image of their transversus abdominis, internal oblique, external oblique and associated fasciae was first captured at rest, then during a contraction of the transversus abdominis. Bivariate correlation analyses and hierarchical analyses were performed (significance level: p < 0.05).

Results

The thickness of these three muscles decreases with age ( ρ = -0.66 for external oblique, -0.51 for internal oblique and -0.58 for transversus abdominis), whereas the thickness of their fasciae increases ( ρ = 0.39 for the fascia of external oblique, 0.54 for the fascia between internal oblique and external oblique, and 0.74 for the fascia between internal oblique and transversus abdominis). Transversus abdominis activation decreases with age (r =-0.44). Age accounts for 19.5% of the variance in transversus abdominis activation.

Conclusion

These results demonstrate that normal aging is associated with changes in deep abdominal myofascial structures and transversus abdominis activation. Assessment of these metrics can provide valuable baseline information for physical therapists involved in rehabilitation and strengthening programs targeting older individuals.

Interprofessional Inconsistencies in the Diagnosis of Shoulder Instability: Survey Results of Physicians and Rehabilitation Providers
Authors: Nicolozakes Constantine P , Li Xinning , Uhl Tim L , Marra Guido , Jain Nitin B , Perreault Eric J , Seitz Amee L
Published: August 2021

Background

Clinicians of many specialties within sports medicine care for athletes with shoulder instability, but successful outcomes are inconsistent. Consistency across specialties in the diagnosis of shoulder instability is critical for care of the athlete, yet the extent of divergence in its diagnosis is unknown.

Hypothesis

Physicians differ from rehabilitation providers in which findings they deem clinically important to differentiate shoulder instability from impingement, and in how they diagnose athlete scenarios with atraumatic shoulder instability.

Study Design

Cross-sectional study.

Methods

Physicians (orthopaedic surgeons, primary care sports medicine physicians) and rehabilitation providers (physical therapists, athletic trainers) were asked via an online survey to rate clinical factors used to diagnose shoulder instability. Clinicians were also asked to diagnose two athlete scenarios with concurrent clinical findings of atraumatic shoulder instability and impingement, differentiated by the absence or presence of a positive sulcus sign.

Results

Responses were recorded from 888 clinicians. Orthopaedic surgeons (N=170) and primary care sports medicine physicians (N=108) ranked physical examination factors as more important for the diagnosis of shoulder instability than patient history factors, whereas physical therapists (N=379) and athletic trainers (N=231) preferred patient history factors. Orthopaedic surgeons differed from physical therapists and athletic trainers in their clinical diagnoses for both scenarios (P≤0.001).

Conclusion

A lack of consistency exists among sports medicine clinicians in recognizing which clinical factors are important when used to diagnose shoulder instability and in diagnoses given with concurrent findings of impingement.

ACL Return to Sport Testing: It’s Time to Step up Our Game
Authors: Unverzagt Casey , Andreyo Evan , Tompkins Jeff
Published: August 2021

Patients and physicians have long looked to physical therapists to help determine an athlete’s readiness to return to sport (RTS) following anterior cruciate ligament reconstruction (ACLR). This is a complex decision that must take into account biological healing, joint stability, functional performance, and psychological readiness. Considering that the vast majority of medical professionals use time as the sole determinant of an athlete’s readiness, and few are using performance-based criteria, it appears as though our profession is failing to capture the necessary information to make this weighty recommendation. The time is now to take a hard look at current practice patterns with RTS testing and push the envelope forward. The purpose of this clinical commentary is challenge our failing status quo by disseminating a robust model for RTS testing that incorporates temporal and criterion-based factors, as well as intrinsic and extrinsic data.
