Due-window assignment scheduling with learning and deterioration effects
Authors: Lin Shan-Shan
Published: April 2021

This paper considers single machine due-window assignment scheduling problems with position-dependent weights. Under the learning and deterioration effects of jobs processing times, our goal is to minimize the weighted sum of earliness-tardiness, starting time of due-window, and due-window size, where the weights only depends on their position in a sequence (i.e., position-dependent weights). Under common due-window (CONW), slack due-window (SLKW) and different due-window (DIFW) assignments, we show that these problems remain polynomial-time solvable.

Authors: Angulo-Fornos Roque , Castellano-Román Manuel , Pinto-Puerto Francisco
Published: April 2021

Este artículo presenta diferentes estrategias de modelado digital del proceso constructivo de un elemento arquitectónico en un entorno HBIM, analizando los Niveles de Conocimiento –LOK– que permiten cada una de ellas. Partiendo de la captura digital fotogramétrica de uno de los muros de la fachada de las dependencias capitulares de la catedral de Sevilla, se ha generado un modelo conceptual inicial orientado a la definición genérica del bien y a su encuadre dentro del conjunto catedralicio. Posteriormente, con objeto de experimentar la potencialidad de aplicación de estas herramientas al análisis arqueológico y arquitectónico, se han transportado sus resultados a este entorno HBIM, alcanzando la caracterización tridimensional de cada una de sus unidades constructivas básicas de la fachada a diversos niveles, desde unidades estratigráficas formadas por regiones hasta las unidades materiales de cada sillar. Por lo tanto, la lectura estratigráfica no se limita al análisis de una superficie de un paramento aislado, sino que se aborda desde su realidad tridimensional general, la catedral. El alto nivel de conocimiento alcanzado en este modelo más desarrollado ha permitido utilizarlo como base para el registro y gestión de la información patrimonial, permitiendo visualizaciones temáticas gráficas y alfanuméricas.
Why Was Waldemar Belck Shot?
Authors: Genç Bülent
Published: April 2021

From the beginning of the 19th century onwards, researchers and travellers from various fields and occupations visited the eastern and southern provinces of the Ottoman State to carry out work related to their fields. Recognition of various archaeological remains and sites dating from different periods, along with the discovery of the East, the region of Mesopotamia and a deep-rooted past resulted in an increased interest by these people in these regions. With the rivalry among some museums in Europe to improve their displays and collections focusing on these regions, the eastern and southern provinces of the Ottoman State became the target of various excavations and surveys. However, these research and investigations that went on throughout the 19th century did not always end in a positive way in terms of the safety of the researchers. Vital problems that could potentially even result in death arose during the work of various researchers at various times in these regions. To give an example, Friedrich Eduard Schulz, a researcher in the region, was killed around Hakkari during his work (Potts, 2017, pp. 249-270; Ainsworth, 1842, p. 294). Waldemar Belck (Fig. 1) also encountered such a situation while he was carrying out research on the Kingdom of Urartu in the region of Van. Belck got injured and could survive only by chance. In this article, I will discuss this incident involving Belck and its consequences.

Authors: Vitkina Galina Yu. , Dmitriev Andrey N. , Alektorov Roman V. , Vyaznikova Elena A.
Published: April 2021

Questions about the oxidative roasting of iron ore raw materials (agglomerates and pellets) are studied. Features of the phase structure of the iron ore raw materials containing titan and vanadium are discussed. Reducibility, durability, and the softening and melting temperatures of metallurgical iron ore raw materials are studied in vitro. The objects of the research are titaniferous ores containing different amounts of titan dioxide. The behaviors of agglomerates and pellets in a blast furnace are studied, and the influence of their physical and chemical properties on heat and mass transfer processes are researched by means of a mathematical model. The main indices of blast furnace smelting—productivity, coke consumption, composition of top gas, cast iron, and slag—are shown. It is established that the increase in titanium dioxide content in pellets, as the amount of concentrate with increased TiO2 content increases, does not cause deterioration in the quality of iron ore raw materials being prepared for blast furnace smelting. At the same time, as the hot strength of raw materials increases, the temperature at which softening begins increases and the temperature interval of softening of materials decreases.

Published: April 2021

The inner-lined layers bonding strength of the ceramic-lined tubing was measured from 25°C to 600°C. The macroscopic structure and microscopic characteristics of the slippage surface of the ceramic-lined tubing were observed using optical microscopy and scanning electron microscopy. Combined with finite element analysis of the residual stress distribution at different temperatures, the shear failure model of the ceramic-lined tubing at different temperatures was given. The mechanical bonding force at the C-A (ceramic layer-alloy layer) interface is greater than the metallurgical bonding force at the A-T (alloy layer-base tubing) interface at low temperature, and the mechanical bonding force at the C-A interface is less than the metallurgical bonding force at the A-T interface at high temperature. The transition temperature is about 200 °C.

Effect of Different Cold Rolling Reduction on the Microstructure and Mechanical Properties of Ti-3573 Titanium Alloy
Authors: Cai Wen Hao , Li Zhuang , Lv Kun Qi , Zhang Li
Published: April 2021

The metastable beta titanium alloy Ti-3Al-5Mo-7V-3Cr (Ti-3573) was used as experimental material in this paper. Different cold rolling reduction was conducted in this titanium alloy. The results show that the total elongation (A50) reached maximum value of 16% after 30% cold rolling. The tensile strength reached maximum value of 910 MPa when the cold reduction increases to 50%. Microstructural evaluation suggested that the precipitation of α phases, deformation twin and stress-induced martensite is responsible for the enhanced tensile properties. Moreover, the TRIP/ TWIP deformation mode contributes to the improvement of the ductility of the titanium alloys.

Published: April 2021

This paper emphasises the effect of the surfactant in the PMEDM process. The preparation of nanofluid is done by mixing and sonicating thoroughly into the deionised water is discussed. The effect of varying the graphene nanopowder concentration into the dielectric is also discussed. Also, the effect of surfactant SDS and CTAB in the machining process is elaborated at 0.1 and 0.2g per 800ml concentration. MRR improved by 21.27% and roughness by 18.91% at 0.2g and 8µs, 2A and 50V in 800ml deionised water. SDS provide better MRR and low roughness compared to CTAB at higher peak current and higher pulse on time Simultaneously, the addition of surfactant into the dielectric medium reduces the performance of the EDM process. The MRR varies from 21mg/min at 0g graphene to 45mg/min at 0.2g and then 31.81mg/min at 0.2g with 0.1g SDS, 43mg/min at 0.2g SDS, 28.33mg/min at 0.1g CTAB and 30mg/min at 0.2g CTAB. Debris size also varies with the input parameters.
Wear Experiment and Influencing Factors Analysis of 13Cr-L80 Tubing String in High-Pressure, High-Temperature and High-Yield Gas Wells
Authors: Guo Xiao Qiang , Liu Jun , Huang Liang , Wei An Chao , Fang Da Ke
Published: April 2021

Due to wear failures caused by tubing string vibrations in high-pressure, high-temperature and high-yield (3H) gas wells, a wear experiment was performed on the 13Cr-L80 tubing string. The influence of contact load, friction frequency, and reciprocating stroke length on the wear characteristics of the tubing string were effectively analyzed using the control variable method. The results demonstrate that, the wear patterns of the tubing-casing were primarily abrasive and adhesive wears, with minimal corrosion wear. The wear amount of tubing increases linearly with the increase of contact load and reciprocating stroke, but increases nonlinearly with the increase of friction frequency, and the friction coefficient of tubing string do not change with the increase of contact load, friction frequency and reciprocating stroke. In-field operations, the service life of the tubing string in 3H gas wells can be effectively augmented by reducing the contact load and longitudinal vibration displacement of the tubing-casing, maintaining the vibration frequency of the tubing string below 1.5 Hz. These results provide useful guidance for designing and implementing approaches to improve the service life of tubing strings in high-yield gas wells.

Novel Electrochemical-Emission Spectroscopy of Metals by White Light Interferometry
Authors: Habib Khaled
Published: April 2021

A white light, i.e., Fabry-Perot, interferometry was unprecedently applied to determine the rate change of the current density (J) of aluminum samples during the anodization processes of the samples in aqueous solutions. The current density(J) values were obtained by Fabry-Perot interferometry rather than the direct current (DC) or alternating current (AC), methods. Therefore, the abrupt rate change of the J was called electrochemical-emission spectroscopy. The anodization of the aluminum samples was conducted by an external DC source in 0.0,2,4,6,8,10% sulfuric acid (H2SO4) solutions at room temperature. In the meantime, the Fabry-Perot interferometry was used to determine the difference between the J of two subsequent values, dJ, as a function of the elapsed time of the DC experiment for the aluminum samples in 0.0,2,4,6,8,10% H2SO4 solutions. The Fabry-Perot interferometry was based on a fiber-optic sensor in order to make real time-white light interferometry possible at the aluminum surfaces in the sulfuric acid solutions. As a result, a new spectrometer was developed based on the combination of the Fabry-Perot, i.e., white light, interferometry and DC method for studying in situ the electrochemical behavior of metals in aqueous solutions.
Correlation among Microstructure, Texture, and Properties along the Thickness Direction in As-Hot-Rolled and As-Solution-Quenched Al7055 Thick Plates
Authors: Zhu Kai , Yan Hong Wei
Published: April 2021

Both microstructure inhomogeneity and mechanical property diversity along the thickness direction in rolled thick aluminum plates have been considered to have a remarkable impact on the performance and properties of the products made from the plates. In this study, scanning electron microscopy (SEM) and electron backscattered diﬀraction (EBSD) characterizations of microstructure and texture types along the thickness directions of Al7055 thick plate specimens prepared using two conditions, hot-rolling and solution-quenching, were performed. To examine the mechanical properties, uniaxial tensile tests were also carried out on specimens machined from both types of thick plates, using a layered strategy along the thickness direction. The results indicate that both the microstructure and mechanical properties are inhomogeneous under the two conditions. Furthermore, it is evident that there is a hereditary relationship between the mechanical properties of the two plates—areas with higher yield strength in the as-hot-rolled plate correspond to areas with the higher yield strength in the as-solution-quenched plate
Awake Self–Prone Positioning: Implementation During the COVID-19 Pandemic
Authors: Allicock Karen A. , Coyne Danielle , Garton Anna N. , Hare Erin C. , Seckel Maureen A.
Published: April 2021

Background

Prone positioning is a well-known beneficial intervention for patients with acute respiratory distress syndrome. As the COVID-19 pandemic emerged, hospitals rapidly adapted prone positioning for acutely ill patients into a new process: awake self–prone positioning. Could a large health care system safely and rapidly implement awake self–prone positioning in COVID-19 units to prevent respiratory failure from progressing among a surge of inpatients?

Review of Evidence

The team extensively reviewed the literature. Using evidence from 22 case reports, peer-reviewed standards, and studies, they developed an awake self–prone positioning guideline.

Implementation

The guideline was implemented in April 2020 in critical care and COVID-19 units. Multimodal education included a concise guideline and real-time support from intensive care unit nurses, clinical nurse specialists, and nursing professional development specialists.

Evaluation

Awake self–prone positioning was a new procedure, and relevant data were obtained from the electronic medical record. From March 18 to August 5, 2020, 1000 COVID-19–related admissions occurred; 272 patients had a high-flow nasal cannula, 111 (41%) of whom had documentation of awake self–prone positioning.

Sustainability

This guideline is now an established part of COVID-19 care and has been integrated into practice in units caring for patients with the disease.

Conclusions

Nurses adapted quickly to using awake self–prone positioning as a plan of care for hypoxic patients. This practice may help hospitals adjust care delivery for these patients and effectively maintain patients in non–intensive care units.

Management of Lower Limb Vascular Injuries in a Tertiary Care Centre
Authors: Garg Ramneesh , Mittal Rajinder K , Kathpal Sheerin Shah , Rakesh Devika
Published: April 2021

Context:

Lower limb vascular trauma accounts for majority of peripheral vascular injuries. Delay in diagnosis and referral to higher centers in developing countries like India poses a major challenge with regard to optimum management of these vascular injuries.

Aims:

The aim was to study the time gap between injury and revascularization and the incidence of reperfusion injuries in patients presenting late to the hospital.

Materials and Methods:

This descriptive prospective study involved 51 patients who presented with clinical signs of vascular injury confirmed by handheld Doppler. In cases presenting late (more than 6 h), decision to proceed with revascularization versus primary amputation was based on distal muscle viability tested intraoperatively. All anastomosis were done under microscopic magnification with the use of venous graft wherever needed.

Results:

All 51 patients in the study were males with a mean age group of 32.6 years. Six patients underwent primary amputation. Road traffic accidents were the most common cause of injury with popliteal artery involvement in most cases. Of the total 45 patients who underwent revascularization, 25 patients (55.5%) presented within the golden period of 6 h and only five patients (11.1%) underwent revascularization within 6 h of injury despite which we had a limb salvage rate of 88.8%. Reperfusion injury was seen in 14 patients, vascular thrombosis in three patients and two deaths were reported.

Conclusions:

We thus recommend that decision to reperfuse the involved limb should not be solely based on the time elapsed but also on factors such as muscle viability and neurological status, especially in a country like India.
Chronic postoperative endophthalmitis with an unusual organism
Authors: Maggon Rakesh , Shahare Kapil Gopal
Published: April 2021

Chronic postoperative endophthalmitis (CPE) following cataract surgery with the appearance of distinct plaques is most commonly caused by Propionibacterium acnes and the standard treatment is intraocular lens (IOL) explant and complete capsulectomy. We report a case of CPE who presented with an indolent recurrent course, manifested numerous typical plaques in the capsular bag, and was treated with an IOL explant, re-implant, and two-port 23G pars plana vitrectomy under direct vision with good results. The organism grown was Bacillus species which is the most common known cause of posttraumatic endophthalmitis and typically has a rapidly devastating course. It is very rare to detect Bacillus species as an incriminating organism in CPE.
Ensuring COVID-19 Vaccines for Migrant and Immigrant Farmworkers
Authors: Thomas Christine M. , Liebman Amy K. , Galván Alma , Kirsch Jonathan D. , Stauffer William M.
Published: April 2021

Migrant and immigrant farmworkers are cornerstones to food security and production in many nations. In the United States, farmworkers have been disproportionately impacted by COVID-19. Because they are considered essential workers, vaccines may be made imminently available to them and offer an opportunity to reduce these COVID-19–related impacts. It is essential for a successful vaccination campaign to address the unique challenges arising from this workforce’s inherently mobile nature and limited access to healthcare. Proposed strategies to overcome these challenges include ensuring farmworkers are prioritized in vaccine allocation and provided cost-free vaccines at convenient locations through partnerships among health authorities, community- and faith-based groups, and health centers with trusted community relationships. Further, a portable immunization record should be used, and coordination of care continued when a farmworker moves to a new geographic location. If implemented well, vaccinating farmworkers can reduce the COVID-19 disease burden among these essential workers, improve public health, and protect food and agriculture production.

Published: April 2021

Background

Self-Regulated Learning (SRL) is defined as the adjustment of the individual's affective, meta-cognitive, and behavioral operations during learning to attain the desired level of academic achievement. It is an important skill for undergraduate students and its ignorance cause anxious behavior, a sense of potential failure, and avoidance of learning situations.

Objective

The objective of the study was to explore the pattern of SRL among medical students from a student perspective aiming to recognize the learning context and to provide recommendations for future support strategies.

Methods

This is a cross-sectional study that targeted a total coverage of medical students at the University of Tabuk, Saudi Arabia using a Self-Regulated Learning Questionnaire which composed of six constructs, namely: environment structuring, goal setting, time management, help-seeking, task strategies, and self-evaluation. An independent-samples test, ANOVA, and post-hoc analysis were conducted.

 

Results

Females agreed on regular practice of the four domains namely: "environmental structuring, time management, help-seeking, and self-evaluation", mean scores: 3.7(SD=1.023), 3.42(SD=1.035), 3.68(SD=0.99), 3.54(SD=0.94) respectively.

Conclusion

This study identified a remarkable difference in SRL among undergraduate medical students. Females outperformed males in self-regulation; however, both genders in the second year have shown a low level in self-regulation in comparison to fifth year medical students.

Authors: Mukangabire Pacifique , Moreland Patricia , Kanazayire Clementine , Rutayisire Reverien , Nkurunziza Aimable , Musengimana Denise , Kagabo Innocent
Published: April 2021

Background

Adolescents living with HIV are vulnerable to depression with a negative effect on treatment outcomes. However, there are little data on the factors associated with depression in adolescents with HIV infection in Rwanda.  

Aim

This article aims to assess the prevalence and sociodemographic factors related to depression among adolescents living with HIV/AIDS.

Methodology

 A cross sectional research was conducted with 102 adolescents living with HIV/AIDS. Depression was measured by Centre for Epidemiological Studies Depression Scale (CES-DC) in its latest version adapted to the context of Rwanda. Chi-square test and binary logistic regression were performed to determine the factors associated with depression.

Results

 The prevalence of participants who had symptoms of depression was 31%. The risk to develop depression increased among HIV infected adolescent who did not attend school or who lived with another person who is not a parent or family member. Having both parents deceased increases the risk to develop depression by 25.07 times compared to when none of them is deceased.

Conclusion

 The results have demonstrated that lack of social support is likely to raise the risk of development of depression symptoms among adolescent with HIV. It is clearly an urgent priority to implement programs that focus on provision and maintenance of psychosocial support to this group in order to reverse the situation.

Authors: Kantarama Evelyne , Uwizeye Dieudonne , Mselle Teddy
Published: April 2021

Background

Regular screening for microalbuminuria among type 2 diabetes patients is less common in most low-income countries while it is an early marker of diabetic nephropathy and cardiovascular complications.

Objective

This study aims to assess the need for regular screening for microalbuminuria among type 2 diabetes patients.

Methodology

 with cross-sectional approach, 124 diabetic patients were recruited at Muhimbili National Hospital, in Tanzania; their age, gender, body mass index, fasting blood sugar levels (by Accu Chek Active Glucometer), random urine albumin levels (by Microalbumin 2-1 Combo Test Strips), and the duration of diabetes were recorded.

Results

The study indicated that 62.1% of the participants were microalbuminuric while 2.4% were macroalbuminuric. The risk of microalbuminuria was 4.55 higher in patients aged 60-69 years (95% CI: 1.32-16.51), and 17.4 times higher in patients aged 70 and above (95% CI: 1.49-202.86) compared to individuals aged below 50 years. Patients with high blood sugar level had a risk of 8.09 times higher compared to those with normal blood sugar (CI: 2.53-25.86). Also, the odds were 7.89 higher in patients who lived with diabetes for 10-14 years compared to those lived with the disease less than 5 years (95% CI:1.33-45.59).

Conclusion

The odds of microalbuminuria increased significantly as the patient gets older, with high blood sugar, and the duration of diabetes. Health policies need to establish programs that enhance care at the diabetic clinic through regular screening for microalbuminuria to reduce the risk of developing kidney and cardiovascular complications.

Ophthalmic Anthropometry among Rural Dwellers in Mashonaland Central Province, Zimbabwe
Authors: Samuel Kyei , Selassie Tagoh , Michael Kwarteng , Evans Aboagye
Published: April 2021

Introduction

The measures of ophthalmic anthropometric parameters may vary among races and ethnic groups but are of immense importance in clinical diagnosis and management of oculo-visual defects. There is paucity of data on these measures among the Zimbabwean population.

Purpose

 The aim was to determine ophthalmic anthropometric parameters among rural dwellers in Zimbabwe.

Methods

Six ophthalmic anthropometric parameters including interpupillary distance (IPD), head width (HW), temple width (TW), length to bend (LTB), and apical radius were measured using a pupillometer, PD rule, Head width calipers, Fairbank facial gauge, and ABDO frame rule.

Results

A total of 471 participants aged 18 to 100 years (mean age = 55.13; SD± 17.33 years). Of the 471 participants, 206 (43.7%) were males and 265 (56.3%) were females. A mean interpupillary distance at far was 65.57 ± 4.80 mm, mean temple width of 12.49 ± 1.53 cm, mean head width of 13.61 ± 1.39 cm and a side length to bend of 10.24 ± 1.20 cm and the apical radius was 9.94 ± 1.37. There was a significant (P < 0.05) difference between the ophthalmic anthropometric parameters of males and females except for temple width and apical radius.

Conclusion

A narrower interpupillary distance but a wider temple width was observed among adult Zimbabweans. A significant difference in ophthalmic anthropometric parameters between males and females were observed except for temple width and apical radius. This should inform eyewear manufacturers and importers of frames on the facial and ocular parameters of Zimbabweans to improve the aesthetics and ensure a comfortable vision for wearers of already-made near vision spectacles for presbyopes.

La estimación de la vida útil sensorial de los productos alimenticios, dentro de ellas las bebidas se han vuelto cada vez más importante en los últimos años debido a los avances tecnológicos y al aumento del interés de los consumidores por ingerir productos frescos, seguros y de alta calidad. La vida útil de la mayoría de los productos alimenticios está determinada por cambios en sus características organolépticas. En este estudio se utilizó una escala hedónica de 9 puntos y el análisis multivariante para analizar la percepción sensorial de bebidas gaseosas, utilizando un panel de 24 personas, de edades comprendidas entre 15 a 20 años. Las marcas de gaseosas elegidas fueron: Inca Kola, Viva, Triple Kola, Oro y Cassinelli. Para el análisis multivariante se utilizó el software R-Studio. La marca Inca Kola obtuvo una mayor valoración promedio (7,52 en aceptación de escala de 1 a 9), siendo el sabor, el dulzor y la intensidad, los atributos que han tenido una mayor influencia en su aceptación.
Decadencia de la teoría del capital humano en los sistemas de educación superior latinoamericanos

El presente artículo es el resultado del análisis de las diversas visiones teóricas que se han desarrollado y surgido desde el mundo de la economía y que se han afianzado y permeado el devenir de los sistema educativos con el impacto en las personas y el desarrollo de los países, poniendo el acento en cómo las decisiones políticas y sociales se han visto orientadas desde esta miradas economicistas de rentabilidad y productividad, más que desde una mirada social.A partir de una revisión y análisis cronológico que va desde los paradigmas neoclásicos convencionales, hasta las nuevas miradas surgidas de la economía de la educación, la reflexión se va centrado en fenómenos como la oferta y demanda y la eficiencia de los sistemas educativos, y cómo estos se van asemejando a cualquier otro proceso productivo. Como conclusión, se establece que la aplicación de visiones económicas presentan inconsistencia entre la ontología que los modelos matemáticos implícitamente presuponen y la ontología que efectivamente caracteriza a la realidad social. En este sentido , la exigencia de formalización implícita en la Teoría del Capital Humano, recorta importantes aspectos de la realidad social que resultan esenciales para comprender y explicar los fenómenos educativos.

La finalidad de esta disertación es mostrar al sector universitario, docente y directivo,estrategias, medios y materiales que les permitan adaptarse con éxito a las realidades emergentes en el ámbito digital,a raíz de la situación con COVID-19, y así poder mantener la viabilidad económica y operativa de las universidades. Hago una contextualización teórica partiendo de una analogía con el pensamiento de Abraham Maslow para identificar las debilidades, limitaciones y riesgos que enfrentan las universidades en América Latina y Estados Unidos. Aplico la teoría de Constraints (TOC) con el propósito de identificar un plan de acción en el seno de las IES, buscar soluciones y elaborar proyectos que permitan una adecuada toma de decisiones y posterior seguimiento y control; generando incentivos y motivando el cambio en el comportamiento en la comunidad universitaria, lo que reduciría los niveles de ansiedad.

Los docentes universitarios tienen como misión la formación de recursos altamente calificados, para ello es necesario que desarrollen una serie de saberes y haceres que los capacite para implementar un nuevo modelo de enseñanza en periodos de educación interrumpida. El artículo reporta el primer avance de un proyecto de investigación que tiene como objetivo desarrollar espacios de reflexión que permitan conocer e interpretar la realidad de los saberes y haceres de los docentes universitarios ante periodos de educación interrumpida. La experiencia investigativa se realizó bajo el paradigma interpretativo, utilizando el método fenomenológico hermenéutico y como técnica de recolección de información grupos focales. Se presentan las categorías emergentes vinculadas hasta la fase de estructuración de los hallazgos, en donde destacan una serie de saberes y haceres enmarcados en: área emocional (autoconocimiento emocional o conciencia de sí mismo, automotivación, empatía o reconocimiento de las emociones ajenas, habilidades sociales), área tecnológica y área de planificacióneducativa. Como reflexión final se tiene que los saberes y haceres anteriores a la pandemia de los docentes deben ser reinventados, ajustándose a los nuevos paradigmas de la educación para buscar nuevas formas de cerrar las brechas generadas por la pandemia y conseguir así una educación de calidad.
Kur’an’da Sosyal Kontrol ve Sıla-i Rahim İlişkisi
Authors: KURUM Muhammed Ahmet
Published: April 2021

İnsanlar yapılarının bir gereği olarak davranışları noktasında oldukça aktif ve esnek bir hareket alanına sahiptir. Bu alan, olumlu nitelikteki davranışları bünyesinde barındıracağı gibi, suç ve sapma eğilimi gösteren olumsuz davranışları da kapsayabilir. Toplumsal sistem içerisinde meydana gelen söz konusu sapma eğilimleri, soyut ve somut düzlemde formüle edilen sosyal kontrol mekanizmalarıyla önlenmektedir. Sosyal kontrolün olmadığı bir toplum düşünülemez. Her toplumda davranışları yönlendiren normlar mevcuttur. Bu mekanizmalar toplumsal değer yargılarının korunarak veya düzeltmeye tabi tutularak, ayrıntılı ve sistemli olarak işlendiği bir toplum dokusu oluşturur. Aynı zamanda sosyal kontrol, toplumların sosyal yaşantılarının, karşılıklı ilişkilerinin, tavır ve tutumlarının yıkıcı etkilerinin sorgulanmasını ve düzeltilmesini gerektiren bir olgudur. Özellikle çağımızda, geleneksel toplumların aksine insanların tavır ve tutumlarında karşılıklı ilişki dengelerinin sınırlı bir nitelik gösterdiği görülmektedir. Kur’an’ın insan ilişkilerine bakışı ise 21. yüzyılın mevcut anlayışından farklılık göstermektedir. Bu nedenle çalışmada Kur’an’da toplumsal hayatı düzenleyen kontrol mekanizmaları ile sıla-i rahim arasındaki ilişki ortaya konulacaktır. Çalışmanın amacı ise Kur’an’da sosyal bir olgu olarak sıla-i rahimi, sosyal kontrolün boyutları olan olumlu kontrol – olumsuz kontrol başlıkları içerisinde ele almaktır. Çalışmada nitel yönteme bağlı olarak tarihsel dokümantasyon tekniği kullanılmıştır. Çalışmada genel olarak, ilişkilerin devamlılığını sağlama noktasında Kur’an’ın sıla-i rahime kazandırmış olduğu işlerlik aracılığıyla edinilen olumlu eğilimlerin, dinin bütünleştirici rolü çerçevesinde toplumsal bir düzen ve istikrar sağladığı sonucuna ulaşılmıştır.
Planlı Davranış Teorisi Bağlamında Kur’an’da Niyet
Authors: MÜJDECİ Seda
Published: April 2021

İnsan davranışlarının kaynağını oluşturan etmenlerin daha iyi anlaşılması için oluşturulan teorilerden bir tanesi Ajzen ve Fishbein tarafından geliştirilmiş olan planlı davranış teorisidir (PDT). Planlı davranış teorisi sayesinde bir davranışın ortaya çıkma ihtimali tahmin edilebilmekle beraber davranışa yönelik amaç belirlenebilir. Aynı zamanda bu teoriye göre kişilerin davranışlarına etki eden en önemli faktör niyettir. Niyet denilince daha çok akla ibadetlerin gerçekleştirilmesi veya kalplerdeki iyi ya da kötü yöndeki arzular gelmektedir. Bunlar doğru olmakla beraber planlı davranış teorisinde kastedilen niyet bir davranışın gerçekleşmesi veya gerçekleşmemesi doğrultusunda kişinin davranışlarının sonuçlarını düşünerek; tutum geliştirmesi, sosyal baskıdan etkilenmesi ve davranışsal kontrol ile hareket etmesidir. İslam dininde ise niyet, istenilen bir şeyi amaçlamada kalbin istenilen şeyde karar kılması ve davranışların meydana gelmesinin kilit noktalarından bir tanesidir. Dolayısıyla bu çalışmanın amacı niyetin Kur’an’da ele alınmasını planlı davranış teorisinin temelini oluşturan “tutum”, “algılanan sosyal baskı” ve “algılanan davranışsal kontrol” başlıkları altında Kur’an’daki etkileşimleriyle ayetler ışığında incelemektir. Kur’an’da niyetin ele alınması ile planlı davranış teorisi arasında ilişkinin kurulabileceği örnek metinler bulgulanmıştır. Çalışma tarihsel dokümantasyon tekniğine uygun olarak işlenmiştir.
Kur’ân’da Din Kardeşliği Bağlamında Sosyal Desteğin Psikososyal Boyutları
Authors: AYGÜN Elif
Published: April 2021

Toplum birbirini ayakta tutan, destekleyen yapılar bütünüdür. Bu yapıların en başında da din gelmektedir. Her bireyin ayrı bir kimliğinin olduğu toplumda, insan varlığını devam ettirmek için hayatının her safhasında sosyal desteğe ihtiyaç duymaktadır. Kur’ân-ı Kerim, yapısı ve içeriği bakımından pek çok toplumsal, ahlaki, insani meseleyi bünyesinde bulundurmakta ve sosyal destek boyutlarını sunmaktadır. Çalışmanın temeli, din kardeşliği bağlamında sosyal desteği; a) duygusal, b) araçsal, c) bilişsel (bilgi) ve d) yaygın destek alanlarında Kur’ân-ı Kerim’in âyetleri ışığında psikososyolojik bir bakış açısıyla değerlendirmektir. Kur’ân-ı Kerim'de din kardeşliği ile ilgili neredeyse bütün konularda sosyal destek yükümlülüğüne göndermeler yapıldığı, bulgular arasındadır. Çalışmanın temelini oluşturan din kardeşliği; dil, ırk, soy, nesep, gözetmeksizin toplumu birleştiren, bütünleştiren ve ortak bir paydada buluşturan bir kavram olup, kavramın doğrudan ümmet olma bilinci ile örtüştüğü gözlemlenmiştir. Din kardeşliği bağlamında yoksulu, yetimi, zorda kalmışı, güç durumda olanı, ayrılığa düşmüş olanı ve mazlumu gözetmek bununla birlikte problemi her neyse bu probleme çözüm bulmak ve hiç değilse yanında olup, destek olmak kardeşlik hakkı olarak belirtilmiştir. Kardeşlik hakkı kapsamında sorumlulukların yerine getirilmesi zorunluluk olarak görülmüş; yapılması halinde ecir, yapılmaması halinde ceza ve kınamalarının beraberinde geleceği Kur’ân-ı Kerim tarafından bizzat ifade edilmiştir.
A IMPLANTAÇÃO DE CONSÓRCIO MODULAR EM UMA INSTITUIÇÃO DE ENSINO NO RIO GRANDE DO SUL: UM ESTUDO DE CASO BASEADO NA INOVAÇÃO DA GESTÃO EDUCACIONAL E NA SUCESSÃO FAMILIAR
Authors: Braga Alexandre
Published: April 2021

A presente pesquisa-ação tem como base principal a inovação na implantação de um método não convencional de sucessão em empresas familiares, inserido na gestão da empresa mãe e desmembrada em consórcio de três escolas. O objetivo do estudo é avaliar a aplicação de um consórcio modular no desmembramento de uma organização em três corporações modulistas, como ferramenta de apoio à sucessão familiar empresarial em empresas de pequeno e médio porte. O artigo defende a possibilidade de aceitação que a associação entre consórcio modular e o planejamento sucessório familiar pode promover uma estrutura empresarial sucessória mais efetiva do que os modelos de processos sucessórios tradicionais. Não foram encontrados estudos anteriores propondo a aplicação dos conceitos de modularização e sua derivação ao consórcio modular como ferramenta auxiliar em um processo sucessório familiar. Deste modo, este artigo torna-se pioneiro na proposição de união destes dois temas. Como resultados, no tocante especialmente à sucessão familiar, o consórcio modular obteve êxito para a finalidade que foi proposto, de modo que fundadores e sucessores demonstram satisfação com os resultados alcançados.
