Dvorní rada Julius Frieser (1843–1908) a identifikace minerálů z jeho sbírky ve sbírce Národního muzea v Praze
Authors: Radoň Miroslav , Velebil Dalibor
Published: November 2021

Julius Frieser (1843–1908) was a prominent mineral collector who contributed to the research of minerals of the Bohemian Central Mountains, especially zeolites. He personally discovered a new mesolite mineral site in Bedřichov near Benešov nad Ploučnicí. He was known among professional mineralogists from Prague and Vienna, as well as among other collectors of minerals, and was a member of the Litoměřice mineral collectors‘ club, which organized regular mineral exchanges in Litoměřice around the turn of the 19th and 20th centuries, visited by famous geologists and mineralogists. He built a large systematic collection of minerals from around the world, which included about four thousand items and 350 species. After his death, the collection, or part of it, was acquired by the collector Julia Schildbach from Mariánské Lázně. Her collection was acquired by the National Museum, Prague in 1946. Among Schildbach‘s minerals, 854 items originally from Frieser have currently been identified.

This paper summarizes the findings of the research aimed at the development of a new method for the integrated processing of naturally occurring and anthropogenic rare-earth raw materials based on the decomposition of rare-earth element (REE) concentrates in the presence of sulfocationite. Sorption and desorption of REE cations on a strongly acidic ion exchanger, sorbent regeneration, and REE recovery from eluates are discussed. A virtually zero-waste integrated process for apatite concentrate is proposed. The generalization of the research findings is aimed at demonstrating the prospects and universality of the proposed resource-saving and environmentally safe approach to the processing of various types of naturally occurring and anthropogenic rare-earth mineral feeds. The new methodology made it possible to develop a number of new hydrochemical processes united by a single approach, providing a qualitative increase in the processing performance of various types of rare-earth mineral feeds. The theoretical foundations of a unified approach to the processing of a wide range of minerals can significantly accelerate and cheapen the implementation of specific process circuits, significantly reduce reagent consumption and waste generation, simplify the separation of rare earth elements and impurities, and the separation of rare earth elements from naturally occurring radionuclides, fluorine, and phosphorus. The study was funded by the Kolarctic CBC 2014-2020 program, Project KO1030 SEESIMA — Supporting Environmental Economic and Social Impacts of Mining Activity.
Impact of device design on the electronic and optoelectronic properties of integrated Ru-terpyridine complexes

Published: November 2021

The performance of nanoelectronic and molecular electronic devices relies strongly on the employed functional units and their addressability, which is often a matter of appropriate interfaces and device design. Here, we compare two promising designs to build up solid-state electronic devices utilizing the same functional unit. Optically addressable Ru-terpyridine complexes were incorporated in supramolecular wires or employed as ligands of gold nanoparticles and contacted by nanoelectrodes. The resulting small area nanodevices were thoroughly electrically characterized as a function of temperature and light exposure. Differences in the resulting device conductance could be attributed to the device design and the respective transport mechanism: thermally activated hopping conduction in case of Ru-terpyridine wire devices or sequential tunneling in nanoparticle-based devices. Furthermore, the conductance switching of nanoparticle-based devices upon 530 nm irradiation was attributed to plasmon-induced metal-to-ligand charge-transfer in the Ru-terpyridine complexes used as switching ligands. Finally, our results reveal a superior device performance of nanoparticle-based devices compared to molecular wire devices based on Ru-terpyridine complexes as functional units.

Published: November 2021

Introduction: Sexually transmitted infections are among the most frequent infections affecting pregnant women. We assessed the transmission of hepatitis B virus, human immunodeficiency virus type 1 and Treponema pallidum to newborns from infected parturients.

Methodology: An observational, cross-sectional, analytical facility-based survey was conducted among 57 newborns in Irene Neto Maternity, Lubango city, Huíla province, Angola. Hepatitis B virus DNA molecular identification was done through nested PCR. Human immunodeficiency virus type 1 proviral DNA detection was carried out by two successive nested PCRs. Real-time PCR was performed to examine the presence of T. pallidum DNA. Amplicons from PCR positive samples were sequenced for identity search and genotype assignment.

Results: Hepatitis B virus DNA genotype E was detected in 3/41 (7.3%) newborns from HBsAg (hepatitis B surface antigen) positive mothers. To analyse the association between mothers HBeAg (hepatitis B e antigen) positivity and hepatitis B virus vertical transmission to newborns, a Fisher's exact test was performed, showing a highly significant association (p = 0.006). Human immunodeficiency virus type 1 provirus or T. pallidum DNA was not detected in any newborn.

Conclusions: To prevent hepatitis B virus vertical transmission in Angola it is important to promote universal antenatal screening, expanding hepatitis B virus markers (viral load and/or HBeAg), risk-based infected mothers’ antiviral therapy and newborn passive immunoprophylaxis.

Introduction: Ocular toxoplasmosis is the most common cause of infectious posterior uveitis worldwide. It can be prenatal or postnatal in origin. Despite estimations that postnatal ocular toxoplasmosis is more prevalent, only several cases of proven postnatal ocular toxoplasmosis have been reported in non-epidemic settings. Here, the clinical evolution of ocular toxoplasmosis of conclusively proven postnatal origin in immunocompetent patients is reported.

Methodology: Postnatal ocular toxoplasmosis was diagnosed based on clinical diagnosis supported by the longitudinal detection of Toxoplasma gondii-specific IgG, IgM and IgA antibodies in the serum as well as by direct detection of the parasite (bioassay) and/or its DNA (real-time PCR) in aqueous humor.

Results: Three cases involved adults in whom ocular toxoplasmosis developed during primary T. gondii infection, as part of the clinical presentation in two and as the sole manifestation in one patient. The fourth patient was a case of inactive ocular toxoplasmosis in a 14-year-old boy, where postnatal infection was confirmed by exclusion of maternal infection. The causative parasite strain was genotyped in only one case and it belonged to genotype II, the dominant type in Europe. One patient acquired the infection in Africa, suggesting an atypical strain.

Conclusions: The distinction between prenatal and postnatal ocular toxoplasmosis is only possible in particular clinical situations, and requires extensive laboratory investigation. Genotyping of the parasite strain involved may be important, particularly if atypical strains are suspected, requiring tailored treatment approaches.

Published: November 2021

Introduction: The first case of severe acute respiratory syndrome 2 (SARS-CoV-2) was imported to Pakistan in February 2020, since then 8,260 deaths have been witnessed. The virus has been constantly mutating and local transmission cases from different countries vary due to host dependent viral adaptation. Many distinct clusters of variant SARS-CoV-2 have been defined globally. In this study, the epidemiology of SARS-CoV-2 was studied and locally transmitted SARS-CoV-2 isolates from Karachi were sequenced to compared and identify any possible variants.

Methodology: The real time PCR was performed on nasopharyngeal specimen to confirm SARS-CoV-2 with Orf 1ab and E gene as targets. The virus isolates were sequenced through oxford nanopore technology MinION platform. Isolates from the first and second wave of COVID-19 outbreak in Karachi were compared.

Results: The overall positivity rate for PCR was 26.24% with the highest number of positive cases in June. Approximately, 37.45% PCR positive subjects aged between 19-40 years. All the isolates belonged to GH clade and shared missense mutation D614G in spike protein linked to increased transmission rate worldwide. Another spike protein mutation A222V coexisted with D614G in the virus from the second wave of COVID-19.

Conclusions: Based on the present findings it is suggested that the locally transmitted virus from Karachi varies from those reported from other parts of Pakistan. Slight variability was also observed between viruses from the first and second wave. Variability in any potential vaccine target may result in failed trials, therefore information on any local viral variants is always useful for effective vaccine design and/or selection.
COVID-19 vaccine demand, hesitancy, and nationalism: a case of protection motivation behavior in Bangladesh
Authors: Rahman Mostafizur , Hossain Afnan , Sufian Abu , Anwar Nahida
Published: November 2021

Introduction: Immunization, as a process of fighting against the COVID-19, has gained important research appeal, but very limited endeavor has been paid for vaccine behavioral studies in underdeveloped and developing countries. This study explores the vaccine demand, hesitancy, and nationalism as well as vaccine acceptance and domestic vaccine preference among young adults in Bangladesh.

Methodology: This quantitative study followed the snowball sampling technique and collected responses from 1,018 individuals from various social media platforms. The analysis covered both descriptive and inferential statistics including chi-square, F-statistic, and logistic regression.

Results: The findings of the fully-adjusted regression model suggest that the individuals who had more vaccine demand were 3.29 times (95% confidence interval = 2.39-4.54; p < 0.001) higher to accept vaccine compared to those who had no vaccine demand. Conversely, vaccine hesitancy was negatively associated with vaccine acceptance. Here, the odds ratio was found 0.70 (95% confidence interval = 0.62-0.80; p < 0.001), which means that those who had higher vaccine hesitancy were about 30% less likely to accept vaccines than those who had no hesitancy. In addition, the persons who had vaccine nationalism were 1.75 times (95% confidence interval = 1.62-1.88; p < 0.001) more prone to prefer domestic vaccine.

Conclusions: This study suggests that policymakers may take initiatives for making people aware and knowledgeable about the severity and vulnerability to specific health threats. In this concern, perception and efficacy-increasing programs may take part in increasing protection motivation behaviors like vaccine acceptance and (domestic) vaccine preference.

Published: November 2021

Introduction: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) affects mainly the lungs causing pneumonia and complications like acute respiratory distress syndrome. Pneumothorax is a rare manifestation of the disease. This report is a description of a series of patients with COVID-19 and spontaneous pneumothorax, some of them with associated pulmonary cysts.

Methodology: Cases were collected retrospectively. We included clinical data from medical records and described radiologic findings. Patients that developed pneumothorax during mechanical ventilation were excluded.

Results: Ten cases were included in this report, nine of them were male. The median age of our series was 62 years (IQR = 57-68). The median days since the onset of symptoms until the development of pneumothorax was 27 (IQR = 17-31), most cases developed after the second week of the diagnosis of pneumonia. Two cases required invasive mechanical ventilation, but pneumothorax occurred after ventilator weaning. Three cases showed subpleural pulmonary cysts.

Conclusions: Cysts and pneumothorax are rare manifestations of SARS-CoV-2 pneumonia with mechanisms not completely understood. This report highlights the role of CT scan in diagnosis of COVID-19 complications.

Authors: Rakhmawati Windy , Nilmanat Kittikorn , Hatthakit Urai
Published: November 2021

BACKGROUND: Preventing tuberculosis (TB) in children needs the family to be engaged; however, limited studies about how the family engages in TB prevention.

AIM: This aimed of study was to develop the process of family engagement in TB prevention for children with household contact of TB patient.

METHODS: Guided by Straussian grounded theory, we developed a substantive theory from 14 primary caregivers in West Java-Indonesia as the key participants of families whose child ≤5 years old received TB screening and preventive therapy, and have had an adult in the household with active TB diagnosis. Data were collected by in-depth interviews and analyzed by coding procedures.

RESULTS: Sustaining togetherness aimed to maintain the children’s health, which underpinned three main stages that consisted of “moving from fear to realization,” “making the family’s collective decision,” and “holding on together.”

CONCLUSION: Implications for nursing practice in providing optimum care of preventing TB among children through engagement of family.

Bats (Order: Chiroptera) is a recognised group of bioindicators due to their sensitivity towards alterations in their immediate surroundings. With the threats of climate change becoming more severe on a daily basis, it is reasonable to collect data on how bat diversity is influenced by elevation. This will be useful to predict and monitor possible upslope shifting of bat species due to increase in surrounding temperature or anthropogenic pressure. Hence, this study aims to uncover the bat diversity trend at different elevations in Crocker Range Park (CRP), Sabah, Malaysia. Bat trappings were conducted in four substations within this park, covering an elevation spectrum from 450 to 1900 m a.s.l. The overall sampling managed to capture 133 individuals of bats, predominantly Pteropodidae, with the addition of two new species locality records for CRP, Murina peninsularis and Hypsugo vondermanni. Simple linear regression analyses revealed that both bat diversity and richness have an inverse linear relationship with elevation. Likewise, the Pearson’s correlation value, associating bat diversity with elevation, also shows that they have a negative relationship at r = -0.852. Heterogeneity of habitats explain this trend, as in the lower counterpart of CRP, lowland forests, which are richer in fruit and insect resources persist. Besides, lower land forests have better niche assortment, due to the distinctive layers stratification, allowing bats utilising different guilds to thrive in the same vegetation profile. This study further emphasises the role of CRP to protect most of the bat species found in Borneo, as well as serving as the baseline data for the future studies that look into the impact of temperature increment towards the upslope shifting of the bat population in CRP.
Comparative Effect of Interactive Multimedia to Text-Based Content for Software Application Courses
Authors: Kivuti Edwin Mwosa
Published: November 2021

This study evaluated the comparative effect of interactive multimedia to text-based content on learners taking a software application course.111 participants took part in the study. The researcher employed the use of web analytics and online surveys to capture data. The study showed that there was a significant difference in the learner`s preference for either type of content. An exploratory study on the learner`s preference of specific interactive multimedia features showed that learners preferred the video presentation and the VDI than the other features. The study also evaluated the comparative effect of the two content types on the learner`s comprehension. For instances where learners made use of interactive multimedia they performed significantly better than instances where learners made use of text-based content. These results suggest that use of interactive multimedia can lead to better comprehension and participation than text-based content in self-paced software application courses.

Published: November 2021

Oxaliplatin is a third-generation chemotherapy drug mainly used for colorectal cancer treatment. However, it is also known to trigger neuropathy whose underlying neurobiological mechanisms are still under investigation and currently available treatments show limited efficacy. It is now established that neurons are not the only cell type involved in chronic pain and that glial cells, mainly astrocytes and microglia, are involved in the initiation and maintenance of neuropathy. Among all the pathogenetic factors involved in neuropathic pain, an oxaliplatin-dependent oxidative stress plays a predominant role. In our study, the antioxidant properties of magnesium (Mg), manganese (Mn) and zinc (Zn) salts were evaluated in order to counteract microglial activation induced by oxaliplatin. The antioxidant efficacy of these metals was evaluated by the means of molecular and morphological assays on the BV-2 microglial cell line. Our data clearly show that Mg, Mn and Zn are able to prevent oxaliplatin-dependent microglial alterations by reducing both oxidative and endoplasmic reticulum stress.

Authors: Doruyter Alexander G.G. , Parkes Jeannette , Carr Jonathan , Warwick James M.
Published: November 2021

Positron emission tomography combined with X-ray computed tomography (PET-CT) has an established role in the management of brain disorders, but may be underutilised in South Africa. Possible barriers to access include the limited number of PET-CT facilities and the lack of contemporary guidelines for the use of brain PET-CT in South Africa. The current review aims to highlight the evidence-based usage of brain Positron emission tomography (PET) in dementia, movement disorders, brain tumours, epilepsy, neuropsychiatric lupus, immune-mediated encephalitides, and brain infections. While being areas of research, there is currently no clinical role for the use of PET-CT in traumatic brain injury or in psychiatric or neurodevelopmental disorders. Strategies to expand the appropriate use of PET-CT in brain disorders are discussed in this article.
Epidemiology of type 2 diabetes in India
Authors: Pradeepa Rajendra , Mohan Viswanathan
Published: November 2021

The burden of diabetes is high and increasing globally, and in developing economies like India, mainly fueled by the increasing prevalence of overweight/obesity and unhealthy lifestyles. The estimates in 2019 showed that 77 million individuals had diabetes in India, which is expected to rise to over 134 million by 2045. Approximately 57% of these individuals remain undiagnosed. Type 2 diabetes, which accounts for majority of the cases, can lead to multiorgan complications, broadly divided into microvascular and macrovascular complications. These complications are a significant cause for increased premature morbidity and mortality among individuals with diabetes, leading to reduced life expectancy and financial and other costs of diabetes leading to profound economic burden on the Indian health care system. The risk for diabetes is largely influence by ethnicity, age, obesity and physical inactivity, unhealthy diet, and behavioral habits in addition to genetics and family history. Good control of blood sugar blood pressure and blood lipid levels can prevent and/or delay the onset of diabetes complications. The prevention and management of diabetes and associated complications is a huge challenge in India due to several issues and barriers, including lack of multisectoral approach, surveillance data, awareness regarding diabetes, its risk factors and complications, access to health care settings, access to affordable medicines, etc. Thus, effective health promotion and primary prevention, at both, individual and population levels are the need of the hour to curb the diabetes epidemic and reduce diabetes-related complications in India.

Published: November 2021

The wide variety of industrial and domestic applications of plastic products has fuelled a global trend in their use. The vast amount of plastic items that are discarded after use, on the other hand, pollutes the environment. In light of this, the current study  investigated the use of Polyethylene Terephthalate (PET) as substitute for natural sand in concrete production. Locally sourced river sand was replaced with industrially ground waste PET in proportions of 4 to 20% at a step of 4% by the weight of natural sand whereas other concrete constituents (cement, granite, water-cement ratio and superplasticizer) were kept constant. A Grade M40 concrete with a mix proportion of 1:1:2:0.35 (cement: sand: granite: water-to-cement ratio) was used for all concrete mixes.  Concrete without PET represents the control. Fresh (Slump) and hardened (compressive, split tensile and flexural) properties of the produced concrete were assessed using standard testing methods. The results showed that the slump of concrete decreased by 1.8% and 12.5% with an increase in PET content from 0 to 20%. The 28-day compressive strength of concrete containing PET was lower than the control. However, concrete with 4% PET compared considerably well with control with the compressive strength value exceeding the target strength of 40 N/mm2 while concretes containing PET beyond 4% had compressive strength below the target strength. The split tensile strength of concrete containing 4% PET was higher than that of the control but exhibited lower flexural strength than the control at the age of 28 days. It was concluded that the reuse of PET as a substitute for natural sand as an alternative waste disposal solution for eco-friendly concrete development and attainment of a pollution-free environment is viable.

Authors: Abubakar H.A. , Yusuf A. , Sanusi Y. , Dandajeh H.A.
Published: November 2021

Petrov-Galerkin finite element scheme for systematic analysis of the dynamics of a rising Taylor bubble and general free surface flow problems is derived and implemented. The validity of the scheme is confirmed by simulating the buoyancy-driven motion of a Taylor bubble through a stagnant Newtonian liquid in a vertical pipe characterised by dimensionless inverse viscosity number and Eötvös number of magnitude 111 and 189, respectively. Comparison of the numerical results for the steady state features defining the nose, film, and bottom regions around the bubble with the experiment shows a good agreement between the numerical simulation and the experiment. The percentage deviation of the numerical computed rise velocity, equilibrium film thickness, and stabilisation length ahead of the bubble from the experimental determined values are 8.4%, 2.3%, and 9.5%, respectively.
Deltaic Lateritic Soil in 1:5:11 Mix Design for Producing Controlled Low-Strength Material (CLSM) for Pavement Backfill
Authors: Oke J.A.
Published: November 2021

Deltaic lateritic soil obtained from Emohua in Rivers State, Nigeria was studied to ascertain its suitability as a substitute to sand in concrete for producing controlled low-strength material (CLSM). Cement, coarse aggregate, as well as lateritic soil which replaced sand was combined in ratio 1:5:11 to produce lateritic concrete using varying water-cement (w/c) ratios at varying curing durations. Variation in the w/c ratios ranging from 0.2 to 0.5 at 0.1 intervals and the curing periods which varied between 7, 14 and 28 days were examined. As with the case with conventional concrete, strength development, as well as cement hydration took place after casting over the curing periods. Recent applications using CLSM recommends that a compressive strength of 8.3 N/mm2 or less is required for materials used as conventional compacted backfill soil or structural fillings. In a situation where future excavation is envisioned, it is recommended that the maximum long-term compressive strength of CLSM should generally have an upper limit of 2.1 N/mm2 for compacted backfill material hence, the lateritic concrete produced in this study using the 1:5:11 mix design at 0.2 w/c ratio, cured for 28 days which gave strength of 5.3 N/mm2 can be used as CLSM which primarily, can be utilized as a substitute for compacted backfill to sub-base and/or subgrade of flexible pavements. Where necessary, super plasticizer can be introduced to increase flowability of the lateritic concrete.

The objective was to analyze the interface between domestic violence and psychological distress from the perspective of women waste pickers. This is a qualitative study with a social constructionist approach conducted with 20 women waste pickers, residents of the Federal District, Brazil. Semi-structured interviews, as an instrument for data collection, and Association of Ideas maps were used to analyze the speech contents. The contents extracted from the collected narratives are divided into three thematic categories: violence producing psychological suffering, resources to deal with violence, and work and psychological suffering among women who work with solid waste. At work, personal memories of the suffering lived and experienced in the present time in the workplace were noticed. In the view of the women, aid resources are scarce, even with the knowledge of the legal resource. However, there were signs of self-knowledge of the right to life, respect and the worth of being a woman. Strategies of resistance with psychosocial, legal, and protection services of women are needed in order to proactively support the reduction of their vulnerabilities and facilitate the expansion of their capacities to address the causes of violence, and to produce networks of care, support, and prevention that include their children.
Assessing the extent and need for disability inclusion in the pharmacy education curriculum in Nigeria
Authors: Adedeji Oluwakorede
Published: November 2021

Background: Disability is a prevalent problem in Africa, particularly in Nigeria. The impairment in physical abilities such as hearing, visual, etc. necessitates the need for a specialised approach in the treatment of persons with disabilities by healthcare professionals, including pharmacists. Pharmacists play a central role in the healthcare system among other health professionals because they are usually the first point-of-contact of patients and also play a key role in community surveillance.
Aim: In a bid to achieve disability inclusion in Nigeria, it is thus necessary to equip pharmacists with the necessary skills in the care of patients with disabilities, whether intellectual or physical. 
Method: In this paper, the minimum academic benchmark for awarding the Bachelor of Pharmacy degree (which is the minimum degree that allows one to practice) is well-reviewed and analysed for the presence of any content related to persons with disabilities.
Conclusion: Preparing future pharmacists through the pharmacy education curriculum is a useful way to improve the attitude and skills of pharmacy students in the pharmaceutical care of patients with disabilities.
Households and real estate: Strategies of accumulation and inequality in Spain, 2002-2017
Authors: Boertien Diederik , López-Gay Antonio
Published: November 2021

Real estate has traditionally been an important economic resource for Spanish households. The development of the real estate market in Spain during the 21st century brings forth two very different stories. The first story is one of obstacles to access housing. It has become increasingly hard to buy or rent a home. Housing prices have risen considerably in urban areas while people’s income changed very little. The second story is one of accumulation of properties. Housing has been, and continues to be, a form of saving, investment and speculation for small and large property-owners. Falling housing prices permitted resourceful households to accumulate more properties during the financial crisis. These two stories lead to the following question: How did changes in the ownership of properties impact inequality in Spain? In this Perspectives Demogràfiques, we analyse how developments in the real estate market are connected to wealth inequality in Spain. The results point at a polarization of access to property; both the number of households without property and the number of households with multiple properties increased over time. Because real estate is the most important form of household’s wealth, the accumulation of properties has become a non-negligible part of wealth inequality between households in Spain.
BİLEŞİK SUÇ NİTELİĞİNDEKİ YAĞMA DÜZENLEMESİNİN SUÇTA KANUNİLİK İLKESİ YÖNÜNDEN DEĞERLENDİRİLMESİ
Authors: ŞARE Ersin
Published: November 2021

Hırsızlık ile cebir veya tehdit bir araya gelerek yağma suçunu oluşturmaktadır. Bu nedenle yağma suçu bileşik suç kategorisi içerisinde değerlendirilmektedir. 5237 sayılı Türk Ceza Kanununda yer alan yağma düzenlemesi yönünden sadeleştirilme yoluna gidildiği ifade edilmektedir. Ancak bu sadeleştirme neticesinde, yağma suçu kadar vahim olan hareketler, yağma suçu kapsamından çıkartılmış ve cezası daha hafif olan suçların kapsamına dahil edilmiştir. Hırsızlıktan dönüşen yağmada taşınır mal önce alınmakta cebir ya da tehdit sonra uygulanmaktadır ve bu gibi haller en az yağma suçu kadar vahimdir. Suçta kanunilik ilkesi gereği, kanunda bu yönde düzenleme olmadığı için hırsızlıktan dönüşen yağmanın, ceza kanununda yer verilen yağma hükmü kapsamında cezalandırılması olanaklı değildir. Yargı kararları ve öğretide çoğunlukla hırsızlık suçunda olduğu gibi yağma suçu işlenirken failde “faydalanma maksadı”nın” bulunmasının gerektiği ifade edilmektedir. Yağma suçunun bir unsurunun hırsızlık olduğunu kabul etmek ve yağma suçunun oluşumu için “faydalanma maksadı”nın bulunmasını aramak, bunun yanında da hırsızlık ile yağma suçunun tamamlanma anının farklı olduğunu kabul etmek çelişkiye yol açmaktadır. Dolaylı yağmaya ve hırsızlık suçunda olduğu gibi faydalanma maksadı şeklindeki özel kast unsuruna yağma düzenlemesinde yer verilmesi daha doğru olacaktır.

This qualitative investigation meticulously identified challenges to corporate governance in operations of Multinational Enterprises (MNEs) in diverse situational positions in emerging markets. These challenges are weak macro institutions, strict government interest and influence, over formalized institutional structure, and overbearing political influence and the obvious; information asymmetries. A flexible mixed allegiance paradigm strategy was identified. It provides alignment of diversities and equilibrium based on micro operational efficacies of the multinational enterprise which are experienced and skilled workforce, related to locality of interest, management of loyalty, trust and negotiation hinged on acceptable agreements to member countries. Trust is emphasized as important for international business.

Saberes e Práticas de Mestrandos em Educação do Sudeste Goiano sobre Meio Ambiente
Authors: Faleiro Wender , Geize Kelle Nunes Ribeiro
Published: November 2021

Meio ambiente e sustentabilidade são temas muito discutidos no nosso contexto atual enquanto sociedade, principalmente quando se fala da relação do ser humano com o meio ambiente. Além disso, a discussão sobre esse tema é bastante atual e uma preocupação mundial, na medida que buscamos satisfazer nossas necessidades essenciais e aspirações individuais dentro das possibilidades ecológicas e ambientais. Isso exige uma mudança de valores, comportamentos e estilos de vida, que pode ser alcançada por meio da Educação Ambiental, desde que essa seja explorada como conceito e prática. Mas quais os saberes sobre meio ambiente e práticas sustentáveis permeiam nossas Instituições de Ensino? Com isso, a proposta da nossa pesquisa foi analisar a compreensão de conceitos e práticas ambientais associadas ao desenvolvimento sustentável de Mestrandos em Educação de uma Universidade Federal do sudeste goiano. A mesma se caracteriza como quali-quantitativa, de caráter exploratório, utilizando a técnica de survey para a obtenção dos dados. Encontramos que a maioria dos participantes possuem práticas efetivas e cotidianas para proteger o meio ambiente e promover a sustentabilidade, reconhecendo que os poderes públicos e privados e a sociedade são corresponsáveis pelos cuidados ecológicos. Além disso, as questões conceituais nos revelaram suas subjetividades, dado que enquanto seres humanos somos regidos pelo nosso contexto social, histórico, político, econômico e cultural. Por fim, esse estudo contribui primordialmente com a instituição em que foi realizada a pesquisa, mas também com outras instituição que tenham o interesse de conhecer suas especificidades sobre a problemática, e, com isso, avançarmos nas reflexões, estudos e debates, tendo como foco a construção de sociedades sustentáveis e cidadãos conscientes ecologicamente.

A pedagogia como campo de conhecimento e investigação ou ciência prática da educação que estuda o fenômeno educativo em sua globalidade/complexidade perpassa a implementação da Educação Ambiental. Este texto objetiva explicitar como a proposta pedagógico-curricular do curso de Pedagogia da Universidade Federal de Sergipe (UFS)/São Cristóvão contribui para a formação de professores(as) na perspectiva ambiental. Para tanto, foi analisado o Projeto Pedagógico (PPC), bem como o currículo do curso supracitado. Verificou-se que as contribuições do conhecimento ambiental-ecológico para o campo da Educação Ambiental são incipientes e se conjectura sua possibilidade a partir da disciplina Educação e Ética Ambiental, a qual compõe o núcleo de estudos básicos e, mais especificamente, o eixo campos do conhecimento educacional, uma vez que esse núcleo articulará princípios e concepções de diferentes áreas do conhecimento com pertinência ao campo da pedagogia e dos estudos das relações entre a educação e as problemáticas centrais da sociedade contemporânea, dentre elas a sustentabilidade.

Ao disciplinar o conhecimento científico, fragmentando os saberes como meio de especializar as formas de exploração da natureza, a ciência naturalizou a apropriação, levando o ser humano a pensar-se como um ser superior e externo a natureza. O ensino das ciências ambientais pode contribuir para a reflexão acerca dessas relações socioambientais, valorizando a identidade dos sujeitos e resgatando a outridade no trato com a natureza. O presente artigo apresenta a prática de ensino das ciências ambientais, como caminho para a desconstrução da objetificação da natureza, através da sensibilização do ser humano por meio de oficinas pedagógicas, como o espaço do corpo hídrico e práticas sustentáveis como os Anjos do Rio, que emanam olhares de respeito e outridade sobre os rios Piauí e Vaza-Barris, desenvolvidas em duas pesquisas pertencentes ao Programa de Pós-Graduação em Rede Nacional para o Ensino das Ciências Ambientais (PROFCIAMB) da Universidade Federal de Sergipe.

Published: November 2021

A aplicação de estratégias metodológicas inovadoras, em sala de aula, é fundamental para o processo de ensino e aprendizagem referente à Educação Ambiental (EA) voltado para a análise de degradação dos ecossistemas, a exemplo dos manguezais. Os manguezais recebem influências antrópicas devido à ocupação do seu entorno, que ocasionam vários impactos socioambientais que afetam tanto o próprio manguezal quanto a comunidade local. O artigo visa a analisar como o Modelo de Rotação por Estações estimula a autonomia e o protagonismo estudantil, durante o processo de ensino e aprendizagem sustentado pela EA crítica, a partir do estudo dos impactos socioambientais nos manguezais de Aracaju-Se. Dessa forma, a pesquisa, de abordagem qualitativa, foi estruturada nas seguintes etapas pedagógicas: roda de conversa, Brainstorming e Modelo de Rotação por Estações. Durante as atividades, os alunos dialogaram sobre a temática, responderam à questão norteadora e, em grupos, desenvolveram as propostas contidas nas cinco estações distribuídas na sala de aula e em outros espaços da escola. Os resultados demonstram a relevância de práticas pedagógicas híbridas na formação de sujeitos críticos e reflexivos. A articulação desses elementos pode auxiliar na construção de um novo modelo de racionalidade socioambiental, voltado para a conservação de ambientes naturais, como os manguezais.
