The Expediency of Providing Psychotherapeutic Intervention in Correctional Work with Stuttering Adults
Authors: Gusarov Sergey Valerievich , Chaykin Konstantin Georgievich
Published: September 2024

This article substantiates the relevance of the approach to viewing stuttering as a variant of personality disorder accompanied by negative psychosocial states and the necessity of supplementing therapy for this disorder with psychotherapeutic intervention methods aimed at neutralizing the corresponding states of the patient. A review of the main ideas of contemporary researchers on the problematic phenomenon of stuttering in its psychological and emotional aspects is presented, alongside an analysis of data from conducted experimental research aimed at evaluating the effectiveness of psychotherapeutic intervention in the comprehensive system of stuttering correction. Within the framework of the study, a program aimed at neutralizing dysfunctional psychological states in individuals with stuttering was developed and implemented, involving 12 participants aged between 18 and 27 years. Comparative analysis of data from the experimental group of participants revealed significant differences ‘before' and ‘after' the correction course with psychotherapeutic intervention, as well as in comparison with the control group after speech therapy correction without the use of psychotherapeutic intervention. These findings confirm the effectiveness of the presented methodology. Based on the totality of the data obtained, it can be asserted that the introduction of psychotherapeutic technologies into the system of comprehensive stuttering correction is expedient. This creates a premise for a significant improvement in the psychosocial state of patients, which is important not only for the prevention of relapses but also for enhancing the quality of life of people with stuttering. The implementation of interdisciplinary approaches, akin to the combination of methods and techniques of speech therapy alongside psychotherapeutic technologies, aids individuals with stuttering in mastering psychological methods of regulating dysfunctional states, creating conditions for establishing confident, stable speech.

Authors:   Don State Agrarian University, Pomazkova Elena V.
Published: September 2024

Philosophical thought has always stimulated humanity to reflect on values, goals, and the meaning of exist-ence. In the modern business world, philosophy is transforming into new forms of aspiration alongside finan-cial success to achieve social, environmental, and ethical goals. Realization of one’s place in society and re-sponsibility to society has become the basis for the emergence of entrepreneurial culture. In this article, the author examines the ability of ethical values to influence the mindset of modern businessmen; analyzes and studies the decision-making strategies of successful entrepreneurs who adhere to certain philosophical ideas; explores the relationship between the beliefs of individuals and their implementation of innovative business approaches; investigates ways in which entrepreneurs address ethical dilemmas and overcome complex situa-tions using philosophical ideas. As a result of the study, the extent to which the study of ethical values influ-ences successful business management in the modern world is assessed.
Road Facilities of the Russian Far East in the Period of the New Economic Policy (1922–1927)
Authors:   Far Eastern State Transport University (FESTU), Kovalchuk Michael A. , Samsonova Evgeniia M. ,   Pacific National University (PNU)
Published: September 2024

The article highlights the work on the establishment of the road works management apparatus, the road works themselves carried out in the Far Eastern region after the Civil War and intervention. There were certain organi-zational difficulties in road construction, which were managed only after the creation of the Far Eastern Railway District. The authors give a brief list of restored and under construction dirt and highway roads of both state and local importance. At the same time, particular attention is paid to the construction of the Amur-Yakutsk highway, the laying of which began during the First World War. The article discusses the main problems of the industry’s development: lack of funds, lack of engineering and technical personnel and road workers. This, in turn, caused the need to use the free labor of the surrounding peasants in the construction of local roads. The first steps in the mechanization of road works in the region are highlighted. When writing the article, the authors relied on methodological principles generally recognized in historical science, the most important of which are the principle of objectivity and the principle of historicism.
The History of a Forgotten Expedition
Authors:   Institute of History, Archaeology and Ethnography of the Peoples of the Far East,  Far Eastern Branch of the Russian Academy of Sciences, Beloglazova Svetlana B.
Published: September 2024

This article delves into a little-studied aspect of the history of the Russian exploration of the North – one of the first Arctic expeditions of the Russians in the early XIX century. The appeal to the historical experience of the discovery and study of the New Siberian Islands archipelago is determined by the growing interest in it on the part of world powers in connection with the development of coastal shelf resources and the resumption of the Northern Sea Route. In the Russian historiography the name of M.M. Gedenstrom remained a figure of silence for a long time in comparison with such explorers as F.P. Wrangel, P.F. Anju, G.A. Sarychev, E.V. Toll, who were engaged in the study of this region of the Arctic. However, the expedition of M.M. Gedenstrom is marked not only by the connection with specific tasks of Russian foreign policy and attempts to solve scientific problems relevant for that time, but also with the interests of business development on the islands, the subsoil of which is still rich in valuable fossil raw materials. M.M. Gedenstrom was the first to create a general map of the Novosi-birsk Islands, described them and the coast between the mouths of the Yana and Kolyma rivers, and corrected inaccuracies on previously compiled maps.

It presents detailed information on the primary measures taken by government officials, medical personnel, and public organizations to counteract the spread of infec-tious diseases. The article examines the causes, prevention strategies, and consequences of these epidemics, analyzing the factors that influenced the scale and spread of diseases. The analysis of scientific literature and historical documents reveals how societal development was impacted by the spread of infections and the high mortality rates, as well as how medical practices and treatment methods for various diseases have evolved over time. Conclusion dwells upon the fact that the experience of past epidemics has played a crucial role in humanity's ongoing battle against many illnesses and has significantly altered perceptions regarding the im-portance of preventive measures during epidemics.
Vocational and Technical Education in the Yakut ASSR in the MID-1960s
Authors:   M.K. Ammosov North-Eastern Federal University, Ivanov Nikolai N.
Published: September 2024

The study focuses on the development of vocational education in the Yakut ASSR in the mid-1960s and the creation of a separate republican directorate to modernize the industry. By using little-known archival docu-ments, the article recreates an accurate picture of the development of vocational education in the region, char-acterizing the shortage of educational institutions and personnel despite the high demand from the rapidly de-veloping mining industry. At the beginning of 1964, there were only 11 vocational schools operating in Yakutia, which was clearly insufficient for the needs of the economy. There was an acute shortage of personnel, com-pensated by imported workers with low qualifications, which was partially offset by short-term training courses. The creation of the Yakutsk Republican Department of Vocational Education in 1964 stimulated a significant increase in the number of vocational school graduates and the active construction of new educational and resi-dential buildings.
Transformation of China’s Image in the Far Eastern Press during the Post-Soviet Period (Based on Newspapers from Khabarovsk)
Authors:   Pacific National University, Potapchuk Elena Yu.
Published: September 2024

This article is dedicated to the study of the key meanings and perceptions of Russia’s eastern neighbor, its largest strategic partner in modern conditions – China, as established in Russian public consciousness. Draw-ing on materials from the press of Khabarovsk from 1999 to 2024, the author traces the transformation of the perception of Chinese partners by residents of the Russian Far East. Through an analysis of Khabarovsk news-papers over the past three decades, the researcher reveals that the image of the Chinese and China, which was perceived as irritating and concerning to residents of Russia’s Far Eastern regions at the turn of the 21st century, has shifted to a vaguely official attitude in the 2010s and 2020s. This shift is attributed to the pragmatic strategy adopted by the Russian state toward the People’s Republic of China. By the 2020s, China gradually emerges in Khabarovsk’s media as a preferred and desirable partner, with cooperation being seen as critical not only for the region’s economic prosperity but also for the political image of local authorities.

Authors: Petrukhina Alfiya S. , Pyshnenko Alexandra V.
Published: September 2024

The article discusses the possibilities of various information and educational tools for popularizing Russian culture. The experience of successful organizations in the field of positioning cultural crafts of the peoples of Russia as a modern and popular product is analyzed. As a result, it was found that information and educational technologies have great potential in the field of presenting folk crafts to a wide audience. They make it possible to show products as a standard on the domestic and foreign market. A study of the activities of such large cul-tural crafts enterprises as the Pavlovo Posad Shawl Manufactory and JSC Gzhel Porcelain Factory shows that the use of various tools, including the organization of exhibitions, master classes, virtual excursions, live broad-casts, interaction with famous designers contributes to the fact that the manufactured products acquire the sta-tus of a modern brand. It was revealed that information technologies help to introduce more people to the cul-ture of folk crafts, while the presentation of folk crafts in unusual collaborations and the development of tourism products are very effective.
Human Challenges in the Technological World
Authors:   Grozny State Oil Technical University named after Academician M.D. Millionshchikov, Umarovа Zara Ya.
Published: September 2024

The relevance of this issue stems from the fact that, in a world of innovative technologies, humans have lost their sense of self, integrated into a technological reality, and distanced themselves from real life. A new type of thinking, focused on acquiring information for the sake of success, leads to serious consequences: emotional tension, fatigue, and stress. People have lost their sense of purpose and abandoned continuous self-improvement, prioritizing the satisfaction of material needs in everyday life. Gradually, individuals themselves turn into commodities, mere elements of virtual communication. This results in a reevaluation of values that alters their consciousness and worldview. However, in order to truly live, people need more than just technolo-gy. They also need the ability to take responsibility, understand and accept objective reality, experience joy, pain, and suffering, and critically assess their own actions. A person cannot become part of an inverted world where technology is valued more than humanity itself.
Social Choice of the Individual in Everyday Life
Authors:   Ufa University of Science and Technology, Sabitova Alfiya R.
Published: September 2024

The article examines the peculiarities of a person’s social choice in an everyday situation. Against the back-ground of global transformations, daily life is the most sustainable social education. However, information technologies in various spheres of society have also affected the daily existence of a person, which has led to an interest in an area that previously acted as a background for more significant processes. The study of the phenomenon of social choice in everyday life is interdisciplinary in nature due to its multidimensional and mul-tilevel nature. Analyzing everyday life allows for the identification of the principles governing decision-making processes. The article highlights both the negative and positive consequences of these choices in the context of human activity: anonymity, avoidance of responsibility, and stereotyping. Furthermore, it examines the influ-ence of everyday life as an essential attribute of social existence on the stages of individual decision-making.

Shopping is now easier and more accessible than ever in today’s hurried and connected society. This study was conducted to find out the factors influencing customer satisfaction in online shopping during COVID-19. Some barriers have contributed to the unwillingness of Malaysians because they worry others will take their personal information. Two factors were analyzed in this research, which are Information Quality and e-Service Quality, with a sample size of 150 respondents, and a convenience sampling method was used. A set of questionnaires was distributed online through Google Forms by sharing links in WhatsApp and email. Then, the data is analyzed using Statistical Package for Social Science (SPSS). The result showed that Information Quality and e-Service Quality have different relationships with customer satisfaction in online shopping. The limitations of this study are that the variables may not be sufficient, and there should be more variables to be considered in future research that may have a more significant impact. This study contributes to the realization that customer happiness is the most important factor to prioritize to improve a company’s favourable reputation in the marketplace

Parental involvement has been recognized as a crucial factor in shaping a child's educational outcomes across various subjects, including mathematics. When parents actively participate in their child's education by showing interest, discussing mathematical concepts, and assisting with homework, students are more likely to develop a deeper interest in mathematics. This engagement fosters a positive attitude towards learning the subject and can lead to improved grades and overall academic success. Mathematics has been defined as the study of assumptions and applications and is one of the compulsory subjects in Sijil Pelajaran Malaysia (SPM). The students need to achieve at least a passing grade, since most tertiary educational institutions in Malaysia, especially the public have very strict requirements for enrollment, not to forget the stiff competition. The main purpose of this research is to study how parents’ involvement influences students’ interests, as well as their self-perceptions, and consequently how these elements may affect their achievements in Mathematics. 186 Form Four students from SMK Bandar Baru Bangi were selected as the respondents. A quantitative method, using a questionnaire was opted as instrument for data collection. The collected data was analyzed using the IBM Statistical Package of Social Science (SPSS). The findings showed that majority of parents can provide the essential educational tools for children, such as geometry sets, scientific calculator etc. Most students prefer their parents to engage more in their learning process. There is a statistically positive significant relationship between parents' involvement and students’ achievements, which proves the important roles of parents in improving the interest of their children towards learning. In a nutshell, based on the evaluations done by the students, this study may indirectly assist the parents to identify the ideas and the initiatives that they may take in improving their children’s performances.
Entre Lázaro Cárdenas y el Che Guevara: las izquierdas mexicanas en los años sesenta
Authors: Servín Elisa
Published: September 2024

El artículo aborda las discusiones de las izquierdas mexicanas tras la derrota del movimiento ferrocarrilero y la irrupción de la revolución cubana en 1959. La hipótesis central del trabajo es que el Movimiento de Liberación Nacional (MLN) encabezado por el expresidente Lázaro Cárdenas fungió como un espacio de transición entre una vieja izquierda tributaria del nacionalismo revolucionario y una nueva que impulsó un proyecto político que buscaba transcender esos marcos ideológicos. Aunque el MLN tuvo una efímera existencia en los sesenta, muchos de sus partidarios protagonizaron a lo largo de la década movilizaciones campesinas, protestas estudiantiles, la irrupción de publicaciones en el ámbito cultural y la fundación de guerrillas basadas en el foquismo guevarista. Según la autora, las izquierdas mexicanas transitaron una renovación generacional donde pasaron a primer plano los jóvenes, estudiantes e intelectuales como sujetos posibles de la Revolución.

Malnutrition in Acute Stroke: An Article Review
Authors:   Department of Neurology, Medical Faculty, Universitas Padjadjaran, Bandung, Indonesia, Amalia Lisda
Published: September 2024

The prevalence of malnutrition after stroke varies widely. It is estimated about one-fifth of patients with acute stroke are malnourished on initial hospital admission, while the prevalence of malnutrition ranges from 6.1 to 62%. Energy requirements increase due to stress caused by stroke, while food intake decreases due to impaired ability to eat, so the body will use its fat and protein stores as fuel to produce glucose. Muscle and fat tissue undergo degradation due to the breakdown of amino acids to form energy. Systemic consequences occur after stroke, peripheral immunodepression in association with overstimulation of the autonomic and neuroendocrine systems. Damage to cerebral tissue can activates the hypothalamus-pituitary-adrenal axis, resulting in increased levels of glucocorticoid hormones, catecholamines, and glucagon, leading to hypermetabolism (increased energy use), hypercatabolism (increased protein breakdown), and persistent hyperglycemia. The prevalence of malnutrition increases with the length of stay and decreased functional improvement during rehabilitation. Malnourished patients with stroke experience a higher stress reaction, which increases the occurrence of peptic ulcers, and infections of the respiratory and urinary tracts, thus extending the length of stay and increasing mortality.

Epilepsy prevalent across all ages and genders, making it one of the most widespread neurologic disorder. Worldwide, 20-40% of epilepsy patients are refractory or resistant to oral anti-epileptic drugs, requiring surgery to treat their seizures. The use of electrocorticography (ECoG) can help determine the focus of epilepsy and requires anaesthetic drugs that do not affect the electroencephalography (EEG) readings during surgery. The aim of this case was to study the effect of using dexmedetomidine (DEX) as additional to maintenance anesthesia in epileptic craniotomy surgery with ECoG. A 28-year-old man came to the hospital with complaints of recurrent seizures, generalized tonic-clonic type seizures that lasted 2-3 minutes, was unconscious during the seizure, fell asleep afterwards, and recurred 2-3 times a day. The patient had suffered from epilepsy since 4 years ago. Physical and supporting examinations were within normal limits. Head MSCT examination with contrast suspected oligodendroglioma. The patient was administered dexmetomidine while underwent epilepsy craniotomy surgery with ECoG to remove the tumor which was suspected to be the epileptic focus. The choice of anesthetic agent in epilepsy craniotomy, especially when involving ECoG modalities, requires special consideration to improve intraoperative quality and postoperative outcomes. Propofol is the most widely used induction agent. However, these agents have anticonvulsant effects and activate non-specific spike waves in large areas of the brain. This has the potential to interfere with spike wave monitoring with ECoG. The use of dexmedetomidine has been shown to produce a stable hemodynamic effect and does not affect the ECoG readings. The use of DEX as an adjuvant in anesthesia maintenance does not inhibit spike waves during surgery, so ECoG can be used effectively for anesthesia in craniotomy operations with ECoG.

Intracranial masses can arise from a variety of aetiologies, including congenital, neoplastic, infectious, or vascular processes, each requiring distinct diagnostic and management considerations. Establishing the presence or absence of intracranial hypertension is a critical component of the preoperative evaluation for patients undergoing craniotomy for mass lesions. Hemodynamic is an examination of the physical aspects of blood circulation, cardiac function and physiological characteristics of peripheral vasculature. A 74 year old man was admitted to the hospital because of cephalgia, and left limb weakness. Previously, the patient often felt headaches that came and went since six months ago. Three days before being admitted, the patient felt weak in his left limb and experienced decreasing in consciousness. The patient was given thiopental because the onset of action of thiopental was very short. Administration of intravenous doses of thiopental can cause cerebral vasoconstriction. Sufentanil was administered as an analgesic, because sufentanil is an opioid that has a rapid onset and analgesic potential, compared to fentanyl, intravenous and sufentanil is 5–10 times stronger. This efficacy to maintain adequate cerebral perfusion pressure (CPP), reduce cerebral blood flow (CBF), maintain normal autoregulation, reduce cerebral metabolic rate for oxygen (CMRO2). Arterial cannulation with continuous transduction is considered the gold standard for blood pressure monitoring during anaesthetic procedures. Rapid fluctuations in blood pressure can occur due to patient positioning, surgical manipulation, and the effects of anaesthetics drugs, and close monitoring of these changes is crucial for maintaining hemodynamic stability. The impact of anaesthetic management on CBF is also an integral component of neuroanesthesia, as increases in CBF are associated with increases in cerebral blood volume (CBV). An effective neuro-anesthesia management program that incorporates both invasive blood pressure monitoring and optimization of cerebral perfusion that can help preserving hemodynamic stability and improving outcomes for patients undergoing craniotomy surgery
Research into the Structure and Adhesion of WCCoCr Coatings Plasma-Sprayed onto Castings of AlSi Alloy Plates
Authors: Radoń M. , Opiekun Z. , Kupiec B.
Published: September 2024

The article presents structural investigations and mechanical properties of hard coatings deposited by spraying WCCoCr powder in an argon-hydrogen plasma jet onto the surfaces of AlSi10Mg alloy casting plates. Two variants (A and B) of processing parameters of the powder spraying process onto the surface of silumin plates were applied, resulting in different coating thickness. The coating applied according to variant A was done with 12 passes, and its thickness was approximately 150 μm. The coating applied according to variant B was done with 20 passes, and its thickness was about 320 μm. The microstructures of these coatings are similar, consisting of wavy, alternately deposited phases of solid solutions with varying concentrations of elements, and fine spherical phases, irregularly dispersed carbides. A qualitative analysis of the distribution of microstructure components was performed based on surface mapping. Precipitates differing in their degree of grayness and shape were identified based on microanalysis of their chemical composition. The porosity assessment of coatings performed in five randomly selected areas amounts to an average of 9%. The applied coatings exhibit good adhesion to the substrate, as evidenced by the absence of delamination during scratching tests using a diamond Rockwell indenter loaded with a force of 10 N. The coating hardness averaged 1180HV0.2. The test results indicate the high quality of the WCCoCr coatings, regardless of their thickness.

Aby zbadać charakterystykę pękania pod obciążeniem quasi-statycznym określonej rudy wolframitu, opracowano model kruszenia skupisk cząstek rudy przy użyciu modelu Tavaresa. Charakterystykę pękania skupisk cząstek rudy pod obciążeniem quasi-statycznym zbadano poprzez symulację, a wyniki porównano z danymi eksperymentalnymi z testów kruszenia. Wyniki badań wykazały, że przy różnych obciążeniach quasi-statycznych rozkład wielkości cząstek po kruszeniu znacznie się różnił. Wraz ze wzrostem obciążeń quasi-statycznych zwiększał się udział mniejszych cząstek po kruszeniu, co wskazuje na wyższy stopień rozdrobnienia skupisk cząstek rudy. Dodatkowo, w miarę dalszego wzrostu obciążenia quasi-statycznego, średni rozmiar cząstek w skupiskach cząstek rudy zmniejszał się. Średni rozmiar cząstek stanowił bezpośrednią i intuicyjną miarę stanu rozdrobnienia skupisk cząstek rudy. Co więcej, skupiska cząstek rudy wykazywały fraktalne wzory przy quasi-statycznym obciążeniu, z fraktalnym wymiarem rozkładu wielkości cząstek w zakresie od 0,9205 do 1,3603 przy różnych obciążeniach quasi-statycznych. Wymiar fraktalny wzrastał wraz ze wzrostem obciążenia quasi-statycznego, wskazując na wyższy stopień kruszenia. Co więcej, wymiar fraktalny skupisk cząstek rudy podczas quasi-statycznego obciążenia wykazywał tendencję malejącą wraz ze średnim rozmiarem cząstek kruszenia. Badanie to przyczynia się do wszechstronnego zrozumienia charakterystyki fraktalnej związanej z quasi-statycznym pękaniem obciążeniowym skupisk cząstek rudy

Theoretical Reference: Identifying, tracking, and analyzing weed infestation levels in rice crops are essential for developing more effective control strategies, ultimately enhancing efficiency, reducing costs, and minimizing environmental impact. This study focuses on the geographic distribution and abundance of species within the Pycreus genus (family Cyperaceae) in rice fields in Rio Grande do Sul (RS), Brazil.
 
Method: During the 2005/06 growing season, collections and abundance assessments of Pycreus species were conducted across three irrigated rice fields located in three municipalities within five major rice production regions of RS. Plants were collected during vegetative or reproductive stages, dried, and identified using specialized literature. Specimens were then deposited as vouchers in the PEL Herbarium at the Department of Botany, Federal University of Pelotas.
 
Results and Conclusion: The study revealed the presence of Pycreus species in rice fields across RS, with P. polystachyos (Rottb.) P. Beauv. being the most abundant and frequently observed species. P. macrostachyos (Lam.) J. Raynal and P. lanceolatus (Poir.) C.B. Clarke were also identified, though less commonly. The highest abundance of Pycreus species was recorded in the coastal physiographic region, particularly within the Internal Coastal Plain of Lagoa dos Patos and southern rice production areas.
 
Implications of Research: These findings emphasize the need for targeted weed management strategies in rice cultivation, particularly in regions where Pycreus species are most prevalent, to enhance crop productivity and sustainability.
 
Originality/Value: This study provides valuable insights into the distribution and abundance of Pycreus species in RS rice fields, contributing to the understanding of weed dynamics in rice production and offering a basis for the development of more effective control measures.
Scientometric Review on Psychosocial Risk Factors, Stress, and Burnout Syndrome Among Workers in Different Economic Sectors Engaged in Teleworking Mode in Colombia
Authors: Caicedo Adrian Marcel Garcia , Ordoñez Cristian Camilo Osorio
Published: September 2024

Objective: To analyze psychosocial risk factors, stress, and burnout syndrome in workers from different economic sectors who work remotely in Colombia
 
Theoretical Framework: It includes models such as Karasek and Theorel's Demand-Control-Support, Locke's job satisfaction, Siegrist's effort-reward imbalance, Maslach and Jackson's burnout, and Tushman and Nadler's telework. Tejada and Reyes detail specific risks of telework. Scientometrics, since the early 20th century (Cole & Eales, 1917, cited in Araújo & Arencibia), has been used to analyze these models.
 
Method: Quantitative, descriptive, and cross-sectional study with teleworkers in Colombia, using secondary sources such as Scopus. A search was conducted with 'psychosocial risks' and 'Colombia', following quality criteria from Humanante, García & Conde (2017). Data collection and analysis were conducted using R Studio.
 
Results and Discussion: The study highlights that health personnel is the main population analyzed in risks with emphasis on psychosocial factors. Scientometrics in Colombia plays a crucial role in improving occupational health through the use of validated tools and the optimization of research time, obtaining replicable and effective results.
 
Research Implications: It provides information on how the results can be applied or influence practices in the field of Psychosocial Risks. These implications encompass Occupational Safety and Health.
 
Originality/Value: It contributes to the literature with an innovative and relevant approach, highlighting the methodological importance to develop effective solutions to eradicate the causes of the investigated problem.
Motywacje i decyzje wyborcze młodych wyborców w wyborach parlamentarnych z 2023 roku - komunikat z badań.
Authors: Fołta Piotr
Published: September 2024

Artykuł porusza problematykę decyzji wyborczych młodych osób po wyborach parlamentarnych w 2023 roku. Zawiera on próbę wyjaśnienia, jakie były motywacje wyborcze badanej grupy osób. Jest również próbą pogłębienia wątków dotyczących wyborów politycznych i partycypacji młodych wyborców obywateli. Przeprowadzone zostały samodzielne badania jakościowe, techniką wywiadu pogłębionego, które uszczegóławiają problem. Analizy pokazały, że sporo młodych osób głosowało przeciwko rządowi Prawa i Sprawiedliwości, jeżeli chodzi o porównanie z poprzednimi wyborami. Widać także sporą niechęć do sprawowania władzy przez tę partię. Badani przeciwni PiS uzasadniali swoją partycypację wyborczą celem zmiany władzy, gdyż nie byli z niej zadowoleni. Uważali, że to ugrupowanie nie dba o tę grupę wiekową, nie spełnia również ich oczekiwań.
Anadolu-T Etlik Piliç Ebeveyn Hattının Elde Edilmesinde Kullanılan Saf Hatların Canlı Ağırlık ve Yumurta Verim Değişimleri
Authors: Oğuzhan Emrah , Sarıca Musa
Published: September 2024

Türkiye’de etlik piliç ebeveyn ıslah çalışmaları 2015 yılında saf hatlar kullanılarak yeniden başlatılmıştır. Bu çalışmalarda A1 ve A2 ana hatları ile B1 ve B2 baba hatlarında seleksiyon ve melezleme çalışmaları ile ebeveyn üretimi gerçekleştirilmiştir.  Ebeveyn ve hibritlerin verim özelliklerinin ortaya koyulmasıyla, materyal 2020 yılında “Anadolu-T” ismi ile tescil edilmiştir. Saf hatlarda 2016 yılında uygulanan ıslah programına göre büyütme döneminde; canlı ağırlık (CA), canlı ağırlık artışı (CAA), 49-63 günlük yemden yararlanma oranı (YYO), 49. gün göğüs alanı (GA) ile kanat tüylenme hızına ait kalıtımın korunması gibi özelliklere göre seleksiyon yapılmıştır. Yumurtlama döneminde ise; ana hatlarında yumurta verimi (YV), baba hatlarında ise döllülük oranı yönünden seleksiyona devam edilmiştir. Böylece farklı özelliklere sahip saf hatların hem ticari damızlık hem de ticari etlik piliç performansları geliştirilmeye çalışılmıştır. Bu çalışmada, uygulanan ıslah programına göre 2017-2022 yılları arasında saf hatlardan elde edilen bazı veriler değerlendirilmiştir. 40 haftalık yaşta üretilen kuluçkalık yumurta veriminin kabul edilebilir düzeyde olduğu görülmüştür. Hem ana hem de baba hatlarında CA, YYO ve GA gibi özelliklerde saf hatlarda ilerleme sağlandığı görülmektedir. Ticari firmalardan damızlık satın alarak üretim yapan Türkiye açısından, mevcut saf hatlar önemli bir kapasite sağlayacak düzeydedir. Uygun çoğaltma ve dağıtımla ülkemiz etlik piliç damızlık ihtiyacının %10-15’inin bu materyalle karşılanması mümkündür. Özel sektör ile yapılan paylaşımda damızlıkların verim özellikleri kabul edilebilir düzeyde bulunmuş, 5 haftalık etlik piliç performansları da ticari etlik piliçlerle benzerlik göstermiştir.

Published: September 2024

Infrastruktur penting dalam mendukung terlaksananya pembangunan daerah. Perencanaan program pembangunan desa oleh pemerintah dilakukan dengan pendekatan bottom-up berdasarkan dari keinginan dan keikutsertaan generasi muda sebagai perwakilan masyarakat. Penelitian ini menggunakan metode photovoice yang diterapkan dalam Participatory Extension Approaches (PEA) dengan tahapan photovoice project. Generasi muda berperan sebagai partisipan dalam photovoice project yang terdiri dari 12 anggota karang taruna di Desa Kebak. Tujuan dari penelitian ini yaitu untuk mengungkapkan pandangan pemuda mengenai isu-isu pekerjaan pembangunan infrastruktur dan untuk mengetahui hasil perspektif pengguna terhadap metode photovoice dalam Participatory Extension Approaches (PEA). Hasil penelitian ini antara lain: (1) pandangan pemuda mengenai isu-isu pekerjaan pembangunan infrastruktur yang ditemukan yaitu isu yang di dalamnya terdapat kategori “manajemen” yang dipertimbangkan dari pengelolaan, administrasi, dan sosialisasi, serta kategori “kondisi fisik” yang diukur dari potensi, perawatan, tata letak, dan tingkat kepentingan; (2) perspektif pengguna terhadap metode photovoice dalam participatory extension approaches yaitu kelebihan photovoice project (sebagai dokumentasi bangunan, mengetahui value bangunan, sebagai acuan perbaikan, sebagai acuan pembaruan, dan memberdayakan komunitas) dan kekurangan photovoice project (outcome dari pameran masih belum tuntas sehingga membutuhkan tindak lanjut).

Jalur pejalan kaki merupakan unsur penting dalam keberhasilan Kawasan Berorientasi Transit. Beberapa Kawasan Berorientasi Transit telah ditetapkan di Jakarta, namun dalam implementasinya belum sesuai dengan konsepnya, seperti yang ada di kawasan Lebak Bulus. Penelitian ini bertujuan untuk mengetahui kinerja jalur pejalan kaki di Kawasan Berorientasi Transit Lebak Bulus berdasarkan tingkat kepuasan dan kepentingan pengguna untuk meningkatkaan pelayanan jalur pejalan kaki di Kawasan Berorientasi Transit Lebak Bulus. Indentifikasi dari kinerja ini dilaksanakan dengan menggunakan metode Importance Performance Analysis (IPA). Responden yang ditentukan dipilih secara acak atau juga disebut dengan random sampling sebanyak 31 responden.  Terdapat 23 variabel yang ditanyakan dan responden harus menilai kepuasan mereka serta kepentingan variabel tersebut menggunakan skala likert 1-5. Penelitian ini dilaksanakan secara kuantitatif dengan memanfaatkan aplikasi pengolahan data Microsoft Office Excel maupun SPSS. Hasil penelitian menunjukkan mayoritas variabel memiliki kinerja yang baik dalam tingkat kepuasannya maupun tingkat kepentingannya. Analisis menunjukkan bahwa terdapat dua variabel yang perlu diperbaiki karena belum memuaskan namun memiliki tingkat kepentingan yang tinggi bagi responden. Kedua variabel tersebut adalah Keamanan yang terjamin dari tindakan kriminal dan jumlah pepohonan. Kedua variabel tersebut dapat diperbaiki dengan meningkatkan patroli aparat keamanan serta menambah tumbuhan dan pepohonan yang dapat tumbuh di bawah bayangan.
Thinking with the Spectral: Anti-Blackness in the Hispanophone and Anglophone Caribbean
Authors: Roper Danielle , Baker Jessica Swanston , La Roche Vasquez
Published: September 2024

In the Caribbean, where most of the population is of African descent, experiences of anti-Black racism are encoded in social and political hierarchical schemas. These norms and their discourses manifest in ways that are more often felt—experienced—rather than explicitly and externally discerned and defined. It is this haunting, there-but-not-there, undefinable dimension of anti-Black racism that we seek to explore in its modern Caribbean iterations. This gathering of critical essays and resources from the Hispanophone and Anglophone Caribbean speaks to the lived experiences, contemporary theorizations, and popular engagements with specters of anti-Black racism in the region.
