One of the most harmful biotic factors influencing the stability of sunflower yields is a parasite weed – broomrape (Orobanche Cumana Wallr.). Among the different measures of this parasite control, the usage of genetic resistance is the most ecologic. Lines of the different origin resistant to a race G were developed in V.S. Pustovoit All-Russian Research Institute of Oil Crops. However, inheritance of a trait of resistance was not studied in all lines. Thus, the purpose of this work was studying the genetic control of resistance to a broomrape race G in a line RGM in F2 and BC1. To analyze inheritance, we used the line RGM resistant to the broomrape race G and susceptible to this race the sterile and fertile forms of a line VK 680 of VNIIMK breeding. Resistance of plants in F2 and BC1 was tested in protected ground infected with seeds of a broomrape race G using a method of earlier diagnosis by A.Ya. Panchenko. Reciprocal crosses of the line RGM and susceptible sunflower lines resulted that all obtained hybrids F1 had low middle level of broom-rape infestation. When crossing heterozygous plants F1 and a susceptible parental form of sunflower in BC1 two phenotypes were obtained: susceptible and incomplete resistant (intermediate) in the ratio of 1 : 1. This is typical for monogenic inheritance of a trait. A value x2 was equal 1.38 that certifies the hypothesis the only gen controls resistance of this line with a probability from 0.20 to 0.30. In F2 population splitting for three phenotypical classes was observed: resistant, intermediate, and susceptible in the ratio of 1 : 2 : 1. A value x2 was equal 0.58 that certifies the hypothesis the only gen controls resistance of the studied line with an incomplete dominance with a probability from 0.20 to 0.30.

Mitochondria as microlenses in the eye – the evolution of an improved camera sensor
Authors: Ball John , Li Wei
Published: December 2022

The neurons of the eye that detect light must be very sensitive. They also need ample energy to continuously signal the light they see, so they contain many mitochondria—however, mitochondria scatter light. In our recent study, we show how evolution has found a way to have the best of both worlds: Why not build mitochondria into a lens that helps, rather than hurts, visual sensitivity?

Use of Modified Chitosan and Cationic Starch as Wet Strength Agents on Interleave PaperAbstractWet strength resins commonly used in the paper industry to date are formaldehyde-derived resins, epichlorohydrin polyamide resins, and epoxide resins. These conventional resins have weaknesses such as containing monomer groups that are toxic, difficult to degrade and harmful to health and the environment. Therefore, it is necessary to innovate to overcome these weaknesses, one of which is the development of biopolymer resins. One type of biopolymer is chitosan modified with maleic anhydride so that it has the characteristics of being non-toxic, biodegradable, anti-bacterial, and odorless. With the addition of cationic starch, modified chitosan will work more effectively to produce good strength properties on interleave paper. This laboratory scale study aims to determine the effect of the addition of modified chitosan and cationic starch on the wet and dry strength properties of paper. The test results showed that the addition of 0.7% modified chitosan and 1% cationic starch gave the highest strength properties. The addition of modified chitosan and cationic starch affects the physical properties of the paper such as wet and dry tensile strength index, tearing strength index, bursting strength index, water absorption, and surface pH.Keywords: maleic anhydride, cationic starch, wet strength, interleave paper, modified chitosanAbstrakResin-resin penguat basah yang umum digunakan di industri kertas hingga saat ini adalah resin turunan formaldehid, resin poliamida epiklorohidrin, dan resin epoksida.

Se tuvo por objetivo determinar los estilos de aprendizaje basados en el aprendizaje experiencial de Kolb (1984), a la que corresponden cuatro bucles de funciones cognitivas: estudiante activo o divergencia, reflexivo o asimilador, teórico o convergencia y practicante o acomodado así como, relación de sus modalidades de aprendizaje. El presente artículo, trata del estudio de 103 estudiantes de la Facultad de Ingeniería Metalúrgica y de Materiales de la Universidad Nacional del Centro del Perú. De los resultados, se tiene que el estudiante presenta diferentes formas de estilos de aprendizaje; es así que, en lugar de tratar de comprender y asimilar información, debe ser capaz de dar sentido a lo que ha experimentado y desarrollar conocimientos que le sean útiles. Se concluye que el estilo de aprendizaje predominante en los estudiantes es el divergente, y el de menor predominancia es el asimilador, los que están familiarizados con los campos de la abstracción y la observación de la reflexión; comprender y crear modelos teóricos es una de sus mayores fortalezas, suelen estar más interesados en ideas. Las personas que trabajan en matemáticas o ciencias básicas tienden a adoptar este estilo de aprendizaje. Los asimiladores también disfrutan del trabajo, incluida la planificación y la investigación. Asimismo, la modalidad de aprendizaje de la experiencia concreta se correlaciona con la modalidad de aprendizaje de la experimentación activa con una correlación negativa de – 0.77; lo que implica que, mientras una de las modalidades aumenta la otra disminuye.
Does the 2D Frontal Plane Projection Angle Predict Frontal Plane Knee Moments during Stepping, Landing, and Change of Direction Tasks?
Authors: Straub Rachel K , Powers Christopher M
Published: December 2022

Background

Although dynamic knee valgus can be visually identified using the 2D frontal plane projection angle (FPPA), the validity of the FPPA in terms of predicting frontal plane knee kinematics has been questioned. The biomechanical utility of the FPPA may lie in its ability to predict frontal plane knee moments.

Hypothesis/Purpose

The purpose of the current study was to comprehensively evaluate the ability of the FPPA to predict the frontal plane knee kinetics (peak moment, average moment, and moment at peak knee flexion) across a wide range of tasks (stepping, landing, and change of direction).

Design

Crossover Study Design.

Methods

Three-dimensional lower-extremity kinetics and 2D video were obtained from 39 healthy athletes (15 males and 24 females) during execution of six tasks (step down, drop jump, lateral shuffle, deceleration, triple hop, side-step-cut). Linear regression analysis was performed to determine if the 2D FPPA at peak knee flexion predicted frontal plane knee moment variables during the deceleration phase of each task (peak moment, average moment, moment at peak knee flexion).

Results

The FPPA was found to significantly predict the peak frontal plane knee moment for two tasks (deceleration and side-step-cut, R2 = 12% to 25%), average frontal plane knee moment for five tasks (drop jump, shuffle, deceleration, triple hop, side-step-cut, R2 = 15% to 40%), and frontal plane knee moment at peak knee flexion for five tasks (drop jump, shuffle, deceleration, triple hop, side-step-cut, R2 = 16% to 45%).

Conclusion

An increased FPPA (medial knee collapse) predicted increased knee valgus moments (or decreased knee varus moments) during landing and change of direction tasks (but not stepping). However, the predictive ability of the FPPA was weak to moderate.
Isometric Knee Strength is Greater in Individuals Who Score Higher on Psychological Readiness to Return to Sport After Primary Anterior Cruciate Ligament Reconstruction

Published: December 2022

Background

Anterior cruciate ligament (ACL) injury is extremely common among athletes. Rate of second ACL injury due to surgical graft rupture or contralateral limb ACL injury is approximately 15-32%. Psychological readiness to return to sport (RTS) may be an important predictor of successful RTS outcomes. Psychological readiness can be quantified using the ACL Return to Sport after Injury (ACL-RSI) questionnaire, with higher scores demonstrating greater psychological readiness.

Purpose

The purpose of this study was to investigate differences in functional performance and psychological readiness to return to sport among athletes who have undergone primary ACL reconstruction (ACLR).

Study Design

Descriptive cohort study

Methods

Eighteen athletes who had undergone primary ACLR were tested at time of RTS clearance. The cohort was divided into two groups, high score (HS) and low score (LS), based on median ACL-RSI score, and performance on static and dynamic postural stability testing, lower extremity isokinetic and isometric strength testing, and single leg hop testing was compared between the groups using an independent samples t-test.

Results

The median ACL-RSI score was 74.17. The average ACL-RSI score was 83.1±6.2 for the HS group and 61.8±8.0 for the LS group. High scorers on the ACL-RSI performed significantly better on isometric knee flexion as measured via handheld dynamometry (22.61% ±6.01 vs. 12.12% ±4.88, p=0.001) than the low score group.

Conclusion

The findings suggest that increased knee flexion strength may be important for psychological readiness to RTS after primary ACLR. Further research is indicated to explore this relationship, however, a continued emphasis on improving hamstring strength may be appropriate during rehabilitation following ACLR to positively impact psychological readiness for RTS.

Progressive Loading in a Strongman Following Distal Biceps Repair: Re-Thinking Load Progression – A Case Report
Authors: Lorenz Daniel
Published: December 2022

Background

Rupture of the distal biceps is relatively rare and post-operative protocols are typically vague and are used on many patients, regardless of pre-morbid status. The primary objective is to share the progressive loading strategy used in the rehabilitation of a strongman athlete following a surgical repair of the distal biceps. An additional objective is to highlight the need for individualized protocols and progressions with respect to patient goals and sport demands, as well as the need for shared decision making (SDM) between the medical doctor, patient, and rehabilitation provider.

Case Presentation

The subject is a 39-year-old strong man competitor who suffered a distal biceps rupture while doing a tire flip during training. After having it repaired, the post-operative recovery was unremarkable. The focus of the described intervention was establishing load during rehabilitation exercises that were unique to this individual based on his pre-morbid level of strength and training history as well as the unique demands of his sport.

Outcomes

The patient achieved symmetrical isokinetic strength of the elbow flexors at 60°/second in supine at six months post-operative.

Discussion

The case highlights a successful outcome in a strongman competitor with a distal biceps rupture repair. Typically, protocols are vague and lack specific standards for establishment of load for exercises. Often starting points and progressions are arbitrary and lack rationale tailored to individual needs and/or pre-morbid status. The case offers a framework for establishing and progressing load while also discussing how a shared decision-making model can lead to positive outcomes.
Lower Extremity Kinematic Waveform Analysis During a Single Leg Drop Task – Including a Single Subject Design
Authors: Martonick Nickolai JP , Chun Youngmin , Krumpl Lukas , Bailey Joshua P
Published: December 2022

BACKGROUND

Lower limb asymmetries may be associated with increased injury risk in an active female population. However, an appropriate method for determining these asymmetries has not been established.

HYPOTHESIS/PURPOSE

The purpose of the present study was to examine the single leg drop landing (SLD) kinematic waveforms of female recreational athletes for the pelvis, hip, and knee using statistical parametric mapping (SPM). It was hypothesized that individual bilateral differences would be masked by the group analysis.

STUDY DESIGN

Descriptive Laboratory Study.

METHODS

The current study examined the sagittal and frontal plane pelvis, hip, and knee kinematics of nine physically active females during a SLD. To better elucidate whether asymmetries were present between right and left limbs throughout the landing phase, data were analyzed with SPM. The time-series data were comprised from initial contact to the bottom of the landing. A single subject design was also included to account for potential interindividual variability.

RESULTS

At the group level there were no statistical differences between the right and left limbs of participants for all variables. The single subject design yielded at least two significant asymmetries for all participants. Six out of the nine participants had bilateral differences for all six kinematic time-series.

CONCLUSIONS

The lack of significant differences at the group level may have been masked by movement variability amongst participants. For example, when considering participants with significant differences for hip flexion, four participants had greater values on the left limb and three on the right. A similar observation was made for knee flexion where three participants had significantly greater kinematic values on the left versus four on the right. Until a method is developed to adequately dichotomize lower extremities during the SLD task, a single subject design strategy be used with group analysis when making bilateral comparisons.

Authors: Reep Nathan C. , Leverett Sydney N. , Heywood Rebecca M. , Baker Russell T. , Barnes Darren L. , Cheatham Scott W.
Published: December 2022

Background

Meniscal pathologies are common knee injuries and arthroscopic surgery is the current accepted gold standard for treatment. However, there is evidence to support the use of the Mulligan Concept (MC) Mobilization with Movement (MWM) for meniscal pathologies including the ‘Squeeze’ technique, tibial internal rotation (IR), and tibial external rotation (ER).

Hypothesis/Purpose

The purpose of this systematic review was to critically appraise the literature to investigate the effectiveness of MC MWMs for meniscal lesions on patient reported pain, function, and multi-dimensional health status in patients with clinically diagnosed meniscal pathologies.

Study Design

Systematic Review

Methods

A literature search was completed across multiple databases using combinations of the words “knee, function, mobilization with movement, MWM, mulligan concept, MC, meniscal pathology, meniscal derangement, and meniscal tear.” Studies written within the prior 10 years that examined MC MWM techniques to treat knee meniscal injury were included. Articles that met the inclusion criteria (used MC MWM ‘Squeeze’ technique, tibial IR, or tibial ER for treatment of clinically diagnosed meniscal pathologies; Patient reported outcome [PRO] measures had to be used in the assessment of knee pain or function) were analyzed for quality. Randomized control trials were analyzed using the PEDro scale and the Downs & Black (D&B) checklist, case series were analyzed using the Joanna Briggs Institute (JBI) checklist, and case reports were analyzed using the CARES checklist.

Results

Six articles met the inclusion criteria and were included in this review, two randomized controlled studies, two case series, and two case reports consisting of 72 subjects. All six papers included reports of improvements in pain and function that were either statistically significant or met the minimal clinically important difference (MCID). Five studies reported the Disablement in the Physically Active (DPA) scale that also demonstrated statistically significant differences or met the MCID. The MC MWM ‘Squeeze’ technique, tibial IR, or tibial ER demonstrated the ability to reduce pain, improve function, and improve patient perceived disability following treatment of a clinically diagnosed meniscal pathology. These studies demonstrated short term results lasting from one week to 21 weeks.

Conclusion

Treatment interventions incorporating MC MWM techniques demonstrated reduction of pain and improvement in function in the short term in patients with clinically diagnosed meniscal pathologies.

Penjatuhan Pidana Ganti Rugi Sebagai Pidana Pokok Dalam Kejahatan Terhadap Harta Benda
Authors: Effendi Erdianto
Published: December 2022

This study aims to examine and analyze efforts to resolve cases of crimes against property that have been committed by imposing prison sentences that cannot recover losses suffered by victims. Through the restorative justice approach, judges should be given the option to impose criminal compensation on victims as the main crime that has not been regulated in both the Criminal Code and the Criminal Code Bill. The research method used is normative juridical with a statutory, conceptual, and comparative approach. The results of the discussion of this study provide an alternative to the settlement or enforcement of crimes against property by proposing the imposition of criminal compensation to victims as the main crime. This concept is different from the application of restorative justice so far in Indonesia or abroad which applies it at the level of investigation and prosecution.

Penelitian ini bertujuan untuk mengkaji dan menganalisis upaya penyelesaian perkara kejahatan terhadap harta benda yang selama ini dilakukan dengan menjatuhkan pidana penjara yang tidak dapat memulihkan kerugian yang dialami korban. Melalui pendekatan restorative justice, seharusnya hakim diberikan pilihan untuk menjatuhkan pidana ganti rugi kepada korban sebagai pidana pokok yang ternyata belum diatur baik dalam KUHP maupun RUU KUHP. Metode penelitian yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan, konsep, dan perbandingan. Hasil pembahasan penelitian ini memberikan alternatif penyelesaian atau penegakan hukum kejahatan terhadap harta benda dengan mengusulkan penjatuhan pidana ganti rugi kepada korban sebagai pidana pokok yang wajib dijatuhkan oleh hakim sebagai ide yang baru dalam sistem hukum di Indonesia. Konsep ini berbeda dengan penerapan restorative justice selama ini di Indonesia atau di luar negeri yang menerapkannya di tingkat penyidikan dan penuntutan.

Implikasi Hak Atas Tanah yang Diperoleh Secara Melawan Hukum
Authors: Anggita Vania Digna , Mekka Putra Mohamad Fajri
Published: December 2022

This paper aims to determine the process of legally transferring land rights according to applicable law in Indonesia and to analyze the consequences of unlawful acts in obtaining land rights. The urgency of this research is to provide an explanation of legal certainty in the acquisition of land rights in accordance with Indonesian regulations. There are many disputes over land ownership and control obtained without rights by controlling land whose ownership of the land is already owned by other people. There is a lot of confusion in the community, especially about the legal certainty of the land they own. Proof of ownership in the form of a land certificate is needed to prove ownership of land rights. In addition, authentic deeds made by PPAT also have an important role to prove the transfer of land rights through legal actions. If a person obtains land rights against the law, then any authentic deed of transfer of land rights obtained unlawfully becomes null and void, and land certificates can be canceled by filing for cancellation. This study uses a normative juridical research method. The difference with previous research and this research is that this study discusses the acquisition of land rights transfers in accordance with Indonesian regulations and the consequences of obtaining land rights transfers that are carried out against the law.

Sengketa kepemilikan dan penguasaan tanah yang diperoleh tanpa hak dengan menguasai tanah yang kepemilikan atas tanah tersebut telah dimiliki oleh orang lain saat ini banyak ditemui. Banyak terjadi kebingungan di masyarakat, khususnya tentang kepastian hukum atas tanah yang dimilikinya. Urgensi dari penelitian ini adalah untuk memberikan penjelasan perolehan hak atas tanah yang sesuai dengan peraturan di Indonesia yang memberikan kepastian hukum. Bukti kepemilikan berupa sertifikat tanah sangat diperlukan untuk dapat membuktikan kepemilikan hak atas tanah. Selain itu, akta autentik yang dibuat oleh Pejabat Pembuat Akta Tanah (PPAT) juga memiliki peran penting untuk membuktikan peralihan hak atas tanah melalui perbuatan hukum. Apabila seseorang memperoleh hak atas tanah secara melawan hukum, maka setiap akta autentik peralihan hak atas tanah yang diperoleh secara melawan hukum menjadi batal demi hukum, dan sertifikat tanah dapat dibatalkan dengan mengajukan pembatalan. Penelitian ini menggunakan metode penelitian yuridis normatif. Perbedaan dengan penelitian terdahulu dengan penelitian ini adalah penelitian ini membahas mengenai perolehan peralihan hak atas tanah yang sesuai dengan peraturan di Indonesia serta akibat dari perolehan peralihan hak atas tanah yang dilakukan secara melawan hukum.

Exterior profile of Saanen goats with different genotypes of the SPAG17 gene
Authors: Pozovnikova M. V. , Leibova V. B.
Published: December 2022

The exterior is formed in the process of growth and development of the animal and is a reflection of the appearance and proportions of the body. Genetic factors play a significant role in the formation of the exterior. The protein sperm-associated antigen 17, encoded by the SPAG17 gene, performs a number of important biological functions in the process of growth and development of the mammalian organism, as well as affecting the growth and development of bones. The aim of our work was to analyze the polymorphic variants (indel) of the SPAG17 gene in connection with the body measurements of mature Saanen goats. The sample included 43 goats aged 3-5 years from one of the breeding farms of the Leningrad region. Phenol extraction was used to isolate DNA samples. Genotyping was performed for rs659761737 (indel 14 bp, intron 22) and rs647063466 (indel 17 bp, intron 47) of the SPAG17 gene by AS-PCR method. Before the start of the breeding season, sexually mature goats of the Saanen breed were once measured with the calculation of body built indices. The analysis of the genotypes and alleles frequency showed that, according to rs659761737 (indel 14 bp), the DD genotype was determined at the level of 0.186, ID - 0.419, and II - 0.395. For rs647063466 (indel 17 bp) of the SPAG17 gene, the opposite pattern was observed. The frequency of DD, ID, and II genotypes was 0.326, 0.512, and 0.163, respectively. Animals with genotype II for rs659761737 (indel 14 bp) of the SPAG17 gene had significantly high metacarpus girth values (p˂0.01), and the individuals with genotype ID for rs647063466 (indel 17 bp) were distinguished by high values of the index of leg height (p˂0.05) and chest index (p˂0.05). The obtained data suggest that the studied SNPs of the SPAG17 gene make a significant contribution to the formation of the exterior profile of the Saanen goats.

Compressive and tensile strength of aeolian sand stabilized with porcelain polishing waste and hydrated lime
Authors: Silva José , Santos Júnior Olavo , Paiva William
Published: December 2022

The improvement of sandy soils by incorporating new stabilizing agents in a physical and/or chemical process has become the subject of many studies in recent decades. In addition, the use of industrial wastes in this process can bring significant benefits to the environment and savings in natural resources. This work aims to evaluate the implications of incorporating porcelain polishing waste (PPW) and hydrated lime on the mechanical properties of an aeolian dune sand from the city of Natal/RN. Tests of unconfined compressive strength and split tensile strength were performed on compacted soil specimens with different contents of PPW (10%, 20% and 30%), hydrated lime (3%, 5% and 7%) and relative densities (25%, 50% and 75%). To evaluate the effects of each factor, the Response Surface Methodology with Central Composite Design was used. The results have shown that all three factors have a positive effect on the response variables. The highest strengths were obtained in regions combining high values of relative density and PPW content and an optimum lime content was found. An inversely proportional correlation and good fit to the experimental data was obtained between the strength values and the porosity/binder index (η / Biv). The strength gains were attributed to densification of the soil structure and cementation of the particles by the compounds formed in the reaction between lime and PPW. The results also showed an increase in the strength with curing time, indicating a pozzolanic activity of the mixtures.

Published: December 2022

La evolución del mundo global ha sido propulsada principalmente por el comercio internacional, mejorando la calidad y nivel de desarrollo de las naciones que intervienen en este proceso. Desarrollo por el cual las empresas, mediante un plan detallado, crean condiciones para ingresar al mercado internacional. No obstante, a raíz del inicio de la pandemia se fueron implementando medidas drásticas de bioseguridad y cierre de fronteras, lo que a su vez dio origen a un gran atascamiento comercial alrededor del mundo, ocasionando una crisis de contenedores para exportar productos. La investigación tuvo como objetivo analizar la crisis internacional de contenedores en las exportaciones de banano en el Ecuador durante el año 2021 y se realizó a través de la revisión documental. Este tipo de estudio tiene un enfoque cualitativo a través de los métodos teóricos analítico-sintético, síntesis e inductivo-deductivo. Los resultados obtenidos indican que la industria bananera sufrió una disminución considerable en sus exportaciones y producción, a causa del retraso del envío de materiales y materias primas y de la escasa oferta de contenedores como tal. Sin embargo, el sector se ha logrado adaptar a todas las medidas internacionales e ir recuperando progresivamente la actividad comercial y la estabilidad económica de este pilar fundamental.

Published: December 2022

La presente investigación, aplicada en las cooperativas de ahorro y crédito (COAC) del segmento 1 del Ecuador, tiene como objetivo analizar la relación entre estructura de fondeo y desempeño financiero en un período anterior al inicio de la pandemia del Covid-19. Para dicho fin se utilizó el estimador de los errores estándar corregidos para panel (PSCE). La información fue obtenida de la Superintendencia de Economía Popular y Solidaria del Ecuador (SEPS) y de los sitios web de cada COAC, generando una base de datos compuesta por tres matrices: la primera relacionada con la estructura de fondeo, la segunda con las características de la COAC y la tercera con variables macroeconómicas. Los principales resultados apuntan a un impacto positivo, pero estadísticamente no significativo, del patrimonio en la autosuficiencia financiera. Por otro lado, se evidenció que los recursos financieros del público con mayor costo influyen negativamente en el desempeño de las COAC, sugiriendo la necesidad de una estructura de fondeo menos onerosa para las cooperativas.

In this study, the content and bioaccessibility of minerals were investigated in four different cornelian cherry (Cornus mas L.) and one common dogwood (Cornus sanguinea L.) genotypes grown in Bursa, Turkey. Mineral content or bioaccessibility was determined using inductively-coupled plasma optical emission spectrometry or in vitro artificial gastrointestinal system, respectively. Results revealed that the common dogwood contained significantly greater amounts of minerals, particularly calcium and iron, compared with cornelian cherry genotypes. However, bioaccessibility of calcium or iron was greater in cornelian cherry genotypes (on average 90% or 25%, respectively) compared with that of common dogwood (13.72% or 4.48%, respectively). Bioaccessibility rates of potassium, magnesium and copper were over 50% in all genotypes. Among the cornelian cherry genotypes, G2 contained the highest amount of minerals, except for copper, and the highest amount of bioaccessible minerals. Although the mineral contents were different, amounts of bioaccessible minerals were comparable in both species due to the difference in bioaccessibility rates. In conclusion, the present study shows that fruits with rich mineral contents do not necessarily have high nutritional value due to lower bioaccessibility rates, and suggests that in vitro bioaccessibility studies are useful tools in the determination of the nutritional value of foods.

Örgütsel davranış literatüründe gün geçtikçe daha popüler kavramlar olmaya başlayan narsizm ve sinizmin kökenleri, birçok araştırmada Antik Yunana dayandırılmaktadır. Bu dayanımda narsizmin kaynağı Narkissos miti ile sinizmin kaynağı ise kinizm felsefesi ile bağdaştırılmaktadır. Her ne kadar baskın referanslar bu yönde olsa da bu durumun yanlış bir aktarımdan ibaret olduğunu savunan araştırmalara da rastlamak mümkündür. Narsizm ve sinizmin, mitoloji, örgütsel davranış ve psikoloji gibi birbirinden farklı disiplinlerde çalışılıyor olması tartışmaların sonuçsuz kalmasına neden olmaktadır. Buradan hareketle araştırmanın amacı; narsizm ve sinizm kavramlarının yüzyıllarca gelişen kültürel yapısına ve bu kavramların -modern dünya ile bağdaşımı noktasında- yanlış aktarımı olasılığına ilişkin çekincelerin dile getirilmesini kapsamaktadır.
Ağ Toplumunda Sosyal Medya ve Parasosyal İlişki: Twitter Yorumlarında Survivor Örneği

Published: December 2022

İnternetin gündelik hayatımıza soktuğu, dijital iletişim teknolojilerinin etkileşim bütünlüğü “ağ toplumu” kavramıdır. Bu bütünlükçü kavramın, teknolojik kolaylığı dışında politik, sosyolojik ve ekonomik alanlara yönelikte ciddi sonuçları bulunmaktadır. Ağ toplumunun oluşmasını sağlayan temel zemin internettir. Geniş toplumsal yığınlar internette gerçekte gidemeyecekleri mekanlara ve statülere erişirler. Sosyal medya uygulamalar vasıtasıyla toplumun geniş ama sessiz veya sesi duyulmayan yığınlarına fırsatlar sunmaktadır. Birey bu alanlarda kendi kimliklerini açığa çıkarmadan ikame kimliklerle fikirlerini beyan edebilmektedir. Bu iletişim biçimi ağ toplumunu parasosyal etkileşim noktasında önemli bir merkez yapmaktadır. Parasosyal etkileşimde, toplumun geniş kitlelerinin medya içeriklerinde veya mecralarında gördüğü gerçek veya kurgulanmış karakterlerle olan ilişkisi üzerine dayanmaktadır. Sosyal medya uygulamaları bireylere duygu, düşünce ve isteklerini ifade edebilecekleri alanlar sunmaktadır. Bu çalışmada, ağ toplumunun parasosyal etkileşim içerisinde karşılığı bağlamında, fikirsel düzlemin ağırlık kazandığı bir sosyal medya uygulaması olan “Twitter kullanıcı yorumları” örneklem olarak belirlemiştir. Parasosyal etkileşim ve ağ toplumu ekseninde, @Survivor 2022 All Star hastagi altında program karakterleri hakkındaki kullanıcı yorumları duygusal bağlamda kategorize edilerek incelenmiştir. Çalışma nitel araştırma yöntemi kullanılarak yapılmıştır. Twitter yorumlarından elde edilen veriler Maxqda nitel analiz programında değerlendirilmiştir. Çalışma sonucunda, kullanıcıların gördükleri karakterlerle parasosyal etkileşim içinde oldukları ve yorumların daha çok nefret söylemi ve olumsuz duygular üzerine şekillendiği görülmüştür.

Obezite ile mücadelede, başvurulan güncel çözüm yollarından biri obezite vergisidir. Kalorisi yüksek ancak besleyici değeri düşük gıdaların fiyatını yükselterek tüketimlerini azaltmak obezite vergisinin ana amacıdır. Obezite vergisi birçok ülkede farklı şekillerde kullanılmaktadır ve Türkiye’de uygulanması son dönemlerde tartışılan bir konudur. Bu makalede öncelikle obeziteden genel olarak bahsedilmiş, ardından obezite vergisinin olumlu ve olumsuz yönlerine yer verilmiş ve daha sonra araştırma bulguları sunulmuştur. Bu çalışmanın amacı, obezite vergisinin Türkiye’de uygulanmasına yönelik görüşleri değerlendirmektir. Araştırma evreni, Ankara’da hizmet veren bir aile sağlığı merkezine 01.04.2019-30.05.2019 tarihleri arasında başvuran 18 yaş ve üzeri hastalardan oluşmaktadır. Araştırma kapsamında gönüllülük esasıyla araştırmayı kabul eden 371 hasta ile görüşme yapılmıştır. Araştırmada, Ayyıldız ve Demirli (2015) tarafından hazırlanan anket kullanılmıştır ve elde edilen veriler SPSS programıyla analiz edilmiştir. Araştırmada kullanılan ölçüm aracının yapı geçerliliği, açıklayıcı ve doğrulayıcı faktör analizleri ile değerlendirilmiştir. Katılımcıların cinsiyetinin obezite vergisini destekleme ihtimalleri üzerinde etkili olduğu sonucuna ulaşılmıştır. Kadınların obezite vergisini destekleme olasılığının daha yüksek olduğu saptanmıştır. Katılımcıların büyük çoğunluğunun obezite vergisini desteklemediği ancak vergi dışında araçlar ve politikalarla obezite ile mücadeleyi gerekli gördükleri bulunmuştur.
Covid-19 Sonrası Yoksulluğun Azaltılmasında Yoksul Yanlısı Büyüme
Authors: ALTINIŞIK İsa
Published: December 2022

Yoksulluk ve ekonomik büyüme ilişkisi, iktisat biliminde önemli tartışma konularından birisidir. Ekonomik büyüme refah düzeyinde artış sağlar. Dolayısıyla yoksulların refah düzeyinde de artış olur. Ekonomik büyüme, yoksulluğu azalttığı için yoksul yanlısı büyüme olarak ifade edilir. Yoksul yanlısı büyüme, yoksulluğu hafifleterek, bu artışın Gayrisafi Yurtiçi Hasıla’da görülmesidir. Bunun anlamı yoksulların ekonomik büyümeden zenginlere nazaran daha çok yararlanması olarak kabul edilir. Yoksul yanlısı büyümenin temelini, ekonomik büyümenin yoksulluğun giderilmesinde yetersiz kalmasına dayanır. Bu noktadan hareketle, yoksul yanlısı büyümede bölüşüm, gelir dağılımı eşitsizliği ve gelirin yeniden dağılımı konuları ön plana çıkmaktadır. Özellikle gelirin yeniden dağılımı, ekonomik büyüme açısından topluma eşit yansıtılması büyük önem taşımaktadır. Bu çalışmada, ekonomik büyümenin yoksulluğa etkileri ve yoksulların ekonomik büyümeden ne ölçüde faydalandığı ve faydalanması gerektiği üzerinde durulmuştur. Ekonomik büyümenin etkinliği açısından, gelirin yeniden dağılımının nasıl olması gerektiği üzerinde durulmuştur. Yoksul yanlısı büyüme, gelir dağılımı eşitsizliği ile ilişkilendirilmiştir. Bu çalışmanın temel amacı, Covid-19 pandemisinin savunmasız nüfus üzerindeki etkisini minimize etmek için politika yapıcılara yönelik öneriler geliştirmektir. Bulgular, Covid-19 pandemisinin başlangıcından bugüne kadar kamu harcamalarında, çeşitli demografik gruplar ve yoksullara yönelik sosyal koruma harcamalarını arttırdığı gözlenmiş ve bu desteklerin pandemiyle sınırlı kalmayarak sürdürülebilirlik kazanması önerilmektedir.
