Analysis of question items is very important in learning evaluation because it determines the quality of the evaluation tool used. The aim of this research is to analyze the results of the final semester Arabic evaluation at the Al-Ma’arif Junior High School. The researchers conducted a series of tests consisting of measurements of validity, reliability, differential strength, difficulty level, and debilitating power. The method used in this research is quantitative descriptive method.  The population of the study was 25 students of the 7th grade in the IT High School Building Amal School Year 2022/2023. As for the sample used, the final evaluation of the Arabic semester of the teaching year 2022/2023 was documentation and observation. The result of this study is; in the validity test found 30% of questions can be said to be valid. Then the remaining 70% is declared invalid because it has a significance value <0,05 and the value of R count is smaller than R Table. Then in the reliability test found using Cronbach's Alpha method, and the element of this question is worth 0.625 with the number of questions (N of items) amounting to 40. Difference shows 6 questions in the category "Bad once in distinction, 25 questions in category "badly once in differentiation", 6 issues in the categories "Sufficient enough in distinguishment", 3 questions with category "Good once in distinctness" whereas with the question of category "good once in discrimination" was not found. Difficulty level there are 25 questions with very easy questions category, 14 questions with easy categories, 1 questions with difficult categories. The fractional strength of the answer option A indicates that the question is not working well with the student as the data indicates more fractionals of the question are rejected than accepted. The same applies to options B, C, and D. Thus, a question that does not meet the revised criteria can be concluded or a new question created and tested again. This research can be used as evaluation material for teachers to create quality evaluation tools. Further research can focus on discussing the development of superior evaluation instruments.

The background of this research is At-Tanwir Language Center (ALC) as an extracurricular organization of Arabic language learning for At-Tanwir Islamic Junior and Senior High School students who have an interest and talent in Arabic language. This research used descriptive qualitative research that used interview, observation and documentation techniques for collecting the data. The results of this research showed that supervision of the ALC learning program is internal supervision, active and passive supervision as well as preventive and repressive supervision. Carried out by ALC supervisors through the ALC chair, including active supervision by directly observing the program in progress, and passive supervision by viewing teacher and student attendance lists, teaching journals, and other learning tools. As well as preventive and repressive supervision which carried out to plan and implement the program, it runs effectively and efficiently and this supervision also carried out after learning activities and carried out in order to find out the results of program implementation and evaluate the deviations. Meanwhile, the program evaluation carried out continuously once a month. It also carried out at the end of each learning semester. As for the reporting learning outcomes, ALC divides it into 2 parts, namely short-term and long-term evaluation. This supervision and evaluation carried out for continuous improvement that will be carried out every year to improve the program. Through this research, the monitoring and evaluation management process at course institutions, especially Arabic, is known. As for suggestions for future researchers, they can continue research on the influence of supervision and evaluation on the development of an institution.

Language plays an essential role for human interactions and communication and it can also show cultural, social and individual identity. Ones’ background may generate different language use in either written or spoken contexts. Against this backdrop, this research aims to explore the written language styles of Islamic boarding school and non-Islamic boarding school alumni who learn Arabic as a foreign language. This research is designed under qualitative perspective and employs a case study approach. Data was in the form of documents, obtained through informant essays about the experience of learning Arabic. Besides, the data was also collected through semi-structured interviews with two informants to further understand differences in educational background, differences in first language, family background, foreign language mastered, and exposure to Arabic. Data was analysed by reading essays then providing coding and categorization, which was carried out separately by each researchers, conducting discussions on written language styles focusing on the choice of language used from a sociolinguistic aspect. The results of this research demonstrate that the written language styles of students of Arabic as a foreign language between Islamic boarding school and non-Islamic boarding school alumni have differences in terms of lexical choice, phrases and sentence structure.  Such differences happen because of the way a learner's family background, foreign language mastery, and exposure to Arabic influence the written language style. Moreover, the findings have demonstrated how different academic background, language exposure, and learning impact to one’s language style. Given the limited number of the informant, future research may consider recruiting more diverse and more participants.

In the current digital era, technology plays a crucial role in supporting learning assessment methods. The use of technological devices in learning has become a major requirement in learning. In evaluating Arabic language lessons, a teacher is required to be able to present learning material questions in an innovative evaluation media to meet learning targets. This research aims to describe evaluation in Arabic language learning using formative media in evaluating listening and reading skills. The research employs a reseach and development ADDIE (Analysis, Design, Development, Implementation and Evaluation). Data collection involves literature review, documentation, and questionnaires distributed to 34 students. The results of this research found that formative evaluation media can support and make it easier for teachers to evaluate Arabic language learning, especially listening and reading skills. The media's advantages include diverse question types, audio-visual features, login functionality, scoring for each question item, and time limits for completion. With this conclusion, this media can be a solution for teachers in evaluating students' Arabic language skills. This research is still limited to evaluating listening and reading skills only, so suggestions for further research are to use this media to evaluate speaking and writing skills.

Международная цитогенетическая номенклатура была и остается единым универсальным языком для цитогенетиков любой части мира. Унификация терминов, аббревиатур и формул для описания хромосомных аномалий, наряду с пониманием механизмов, которые приводят к формированию этих перестроек, является основой действующей Международной системы цитогеномной номенклатуры (An International System for Human Cytogenomic Nomenclature – ISCN). Стремительное развитие молекулярных генетических технологий за последние десятилетия заставляет авторов периодически обновлять и дополнять ее новыми данными. Сравнительный анализ версии ISCN 2020 и предыдущей версии цитогеномной номенклатуры ISCN (2016) позволил нам продемонстрировать основные изменения в записи результатов цитогеномных исследований и сделать вывод, что дополнения в номенклатуре отражают современный подход к диагностике хромосомных аномалий.

An International System for Human Cytogenomic Nomenclature has been and remains a single universal language of cytogenetics all over the world. The unification of terms, abbreviations and formulas for describing chromosomal abnormalities, along with an understanding of the mechanisms that lead to the formation of these rearrangements, is the basis of the current International Cytogenomic Nomenclature System (ISCN). The rapid development in the field of molecular genetic technologies in recent decades forces authors to periodically update the nomenclature and supplement it with new data. A comparative analysis of ISCN 2020 and the previous version of the ISCN 2016 allowed us to demonstrate the main changes in the record of cytogenomic study results and conclude that the additions in the nomenclature reflect the current approach to the diagnosis of chromosomal abnormalities.

The basis of the company’s decarbonization is the effective management of greenhouse gas emissions. The article visualizes in graphic material the forecast values of the mass of greenhouse gas emissions in the fuel and energy sector of Russia until 2030 and determines the trends in their changes. Based on the results of the analysis, it was revealed that in order to achieve a low-carbon development path, it is necessary to introduce additional measures to reduce greenhouse gas emissions. The purpose of the scientific research is to develop a corporate carbon management system, which can become a guideline for the development of corporate systems by Russian oil and gas companies.
A reliable system for recording and monitoring greenhouse gas emissions serves as the basis for obtaining up-to-date, complete and reliable data. At the same time, for the quality control of the decarbonization process, a scheme of interaction within the company should be clearly built. The development and implementation of a carbon management system will allow the company to systematically reduce greenhouse gas emissions, which will create conditions for the transformation of climate risks associated with government regulation into the category of opportunities such as entering carbon markets, attracting investors, etc. The authors note that in most large Russian companies have already developed and introduced carbon management systems into production.
After analyzing the current greenhouse gas accounting system of JSC “Zarubezhneft’’, the authors propose to create a carbon management system taking into account the specifics of the company, which consists in organizing activities on the territory of different countries (Cuba, Bosnia and Herzegovina, Egypt, Uzbekistan, Indonesia, Vietnam and Russia). It is proposed to adapt the methodological approaches for calculating greenhouse gas emissions to the requirements of the legislation in force in the territory where the production facilities of the JSC “Zarubezhneft’’ are located, and also to apply national coefficients in the calculation to ensure more accurate emission estimates.
The result of the study is the development of the concept of the carbon management system of JSC “Zarubezhneft’’.

Published: February 2024

Machine translation (MT) and post-editing (PE) have become increasingly important in the professional language industry in recent years. However, not every translation job is suitable for MT and there are many options for carrying out translation/post-editing projects, e.g. no PE, light PE, full PE, full PE plus revision or translation without MT assistance. In 2019, we published a decision tree for post-editing projects (Nitzke et al. 2019) that aimed to take all considerations into account and guide the stakeholders in charge of deciding whether a job is suitable for MT and PE and, if so, what kind of quality assurance might lead to fit-for-purpose translations.

To empirically test our decision tree model now, we developed a semi-structured interview with 21 questions and a scoring task addressing stakeholders who work with MT projects and have to make the decisions which are essential to our model. The interview was carried out with 19 interview partners. In the article, we discuss the interviews’ findings against the background of our model. Further, we present qualitative findings on strategic decisions, risk considerations, as well as the value of translation, working conditions and job profiles. Finally, we present our revised model motivated by the empirical findings.
When minoritized languages encounter MT

Published: February 2024

Machine translation (MT) is improving even for low-resource minoritized languages such as Basque, for which free online engines are available. However, the level of adoption and common practices involving the technology are unknown, even though it has the potential to disrupt a carefully planned Basque language revitalization and sustainability process. To shed light on MT usage habits and perceptions among the Basque community, we report on the results of a survey of language specialists and general users, and a focus group with professional translators and interpreters. The data shows that MT is already becoming more popular among users of all backgrounds and that, overall, the attitude towards the technology is positive, which might result in increased use in the future. However, participants express concern about the impact MT will have on the development of Basque. The results call for further research on the language impact of MT and MT literacy initiatives.

The potential role of dogs as reservoirs of zoonotic infections is one of the major public health problems. Water emergency areas are generally vulnerable zones with a lack of care from the owners who do not have the basic sanitary service conditions. Dogs often feed on waste detecting coprophagia of human faeces facilitated by the final disposal of excreta in open-air defecation. The objective of this research was to determine the presence of intestinal parasitoses in dogs from a sanitary risk area inhabited by a vulnerable human population. Dog faeces were collected by an enema with a soapy solution and processed by the Telemann’s sedimentation technique as well as the Sheather’s flotation procedure besides a direct examination. A number of 703 (79.3%) analyzed dog faeces were parasitized from a total of 886. Ancylostoma caninum (57%), Toxocara canis (24%) and Uncinaria stenocephala (21%) were the most frequent species. The specific richness in the dog population was 17 species. The highest parasitosis frequency was observed among male dogs and those under one-year aged for the total parasitized ones with T. canis, Cystoisospora canis, C. ohioensis, and Giardia spp. High prevalences found in dogs from the present study could indicate that both diagnosis and treatment are not enough to achieve sustainable changes in vulnerable areas. Actions addressed to the environmental factor are essentials in order to avoid reinfections.
Combating Burnout among Family Practitioners: The Role of Self-Care and Organizational Support
Authors:   Assistant Professor of Psychiatry, Wayne State University, USA, Ajluni Victor
Published: February 2024

Despite the waning of the COVID-19 pandemic, the prevalence of burnout among healthcare professionals, particularly family practitioners, is a pressing concern that has far-reaching implications for the well-being of both caregivers and patients. Burnout, characterized by emotional exhaustion, depersonalization, and a diminished sense of personal accomplishment [1], has been linked to a range of negative outcomes, including increased medical errors, reduced patient satisfaction, and a decline in overall healthcare quality [2]. The demanding nature of healthcare, especially in primary care settings, necessitates a proactive approach to self-care to mitigate these risks. Family practitioners often find themselves at the front lines of healthcare, dealing with a spectrum of challenges that span from the clinical to the bureaucratic. The chronic stress associated with these demands can lead to the symptoms of burnout. It is therefore crucial that self-care strategies be viewed not as luxuries, but as essential components of professional practice [3].
Good Vibrations: How Whole-Body Vibration Elevates Mood and Offers a New Avenue for Exercise
Authors:   Assistant Professor of Psychiatry, Wayne State University, USA, Ajluni Victor
Published: February 2024

The correlation between physical exercise and mental wellness has long been established through various studies. This paper extends the discourse to a specific exercise modality—Whole Body Vibration (WBV)—and its potential benefits for mental health. The initial discussion underlines the well-documented positive impact of exercise on mood enhancement and cognitive function. The narrative then transitions to a detailed examination of WBV and its rising prominence as an alternative exercise form, particularly focusing on its ability to improve mental health across different demographics. Notable studies are presented, showcasing the positive effects of WBV on mood, cognitive function, and the autonomic nervous system, especially in elderly populations. A segment is dedicated to analyzing the relationship between Growth Hormone (GH) secretion and mental health, with a special emphasis on how WBV might influence GH levels. Various investigations, differing in methodological approaches and demographics, are highlighted to understand the acute and possibly long-term effects of WBV on GH secretion. The review suggests that WBV could serve as a viable exercise alternative, potentially beneficial for individuals with mobility challenges or those who find traditional exercise regimes daunting. Moreover, the mood-enhancing effects often associated with WBV could partly be attributed to its impact on GH levels. The paper calls for more extensive research to elucidate the underpinning mechanisms and to establish definitive guidelines on WBV application for mental health improvement, which could have broad implications spanning clinical settings, athletic training, and general well-being.

We report two pairs of chiral multi-resonant thermally activated delayed fluorescence (MR-TADF) materials PCP-DiKTa and Czp-DiKTa by decorating a known MR-TADF core, DiKTa, with different [2.2]paracyclophane (PCP) based planar chiral groups. PCP-DiKTa shows narrow sky-blue emission with a full width at half maximum (FWHM) of 44 nm, while the emission of Czp-DiKTa is slightly broader with a FWHM of 66 nm and red-shifted. Both emitters show high photoluminescence quantum yields of 93 and 99% for PCP-DiKTa and Czp-DiKTa, respectively. Enantiomerically pure samples of both compounds show chiroptical properties in the ground state while only Czp-DiKTa exhibited chiroptical activity in the excited state, with dissymmetry factors (|gPL|) of 4×10-4. Organic light-emitting diodes (OLEDs) with PCP-DiKTa and Czp-DiKTa showed maximum external quantum efficiencies (EQEmax) of 25.7 and 29.2%, with EL of 489 and 518 nm, and FWHMs of 53 and 69 nm, respectively. These EQEmax values are higher than those of other reported devices employing PCP-based D-A type emitters. Our work demonstrates that the PCP moiety is not only a powerful building block to develop planar chiral emitters but one that is compatible with the fabrication of high efficiency devices.

The global transition to electric vehicles and large-scale energy storage systems requires cost-effective and abundant alternatives to commercial Co/Ni-based cathodes (e.g., LiNi0.6Mn0.2Co0.2O2) for Li-ion batteries (LIBs). Manganese-based disordered rock-salts (Mn-DRXs) can outperform conventional cathodes at lower cost, achieving >900 Wh/kg-AM (per active material, AM), but such performance has been demonstrated exclusively in cell constructions far removed from commercial viability, namely with diluted electrode films (~70 wt%-AM) containing excessive carbon and binder. Herein, our work involves a comprehensive study to attain AM-concentrated Mn-DRX cathodes (>95 wt%-AM), covering from inherent material properties to the microstructure of electrodes, to address the formidable challenges in Mn-DRX research. We reveal that Mn-DRXs’ failures in AM-concentrated electrodes originate from their extremely low electrical conductivity (10^-10-10^-8 S/cm) and the collapse of the electrical network with volume change over cycling. These failure modes are resolved through electrical percolation engineering and enhancement of electrode mechanical properties, allowing our demonstration of nearly all-AM Mn-DRX cathodes (~96 wt%-AM) and the highest application-level energy density (~1050 Wh/kg-cathode) reported to date. This work further unveils the trade-off role of Mn-content on Mn-DRXs’ electrical conductivity and volume change, providing guidelines for material design to 33 advance Co/Ni-free LIB's technology readiness.

Fungal enzyme-mediated systems have been widely employed for the degradation of environmental contaminants. However, the use of free enzymes is limited by the rapid loss of their catalytic activity, stability, and reusability, which further restricts their catalytic performance. In this work, we developed an enzyme immobilization platform by elaborately anchoring the fungal laccase onto arginine-functionalized boron nitride nanosheets (BNNS-Arg@Lac). BNNS-Arg@Lac showcased enhanced stability against fluctuating pH values and temperatures, along with remarkable reusability across six consecutive cycles, outperforming free natural laccase (nlaccase). As a demonstration, a model pollutant of atrazine (ATR) was selected for proof-of-concept applications, given substantial environmental and public health concerns in agriculture runoff. By applying BNNS-Arg@Lac, the ATR degradation rate was nearly doubled that of nlaccase. Moreover, BNNS-Arg@Lac consistently demonstrated superior ATR degradation capabilities in synthetic agricultural wastewater and various mediator systems compared to nlaccase. Comprehensive product analysis unraveled distinct degradation pathways for BNNS-Arg@Lac and nlaccase, further elucidating the mechanism of the laccase-catalyzed ATR treatment. Overall, this research provides a foundation for the future development of enzymatic catalysts in tackling pollution problems and may unlock new potential for green and efficient environmental remediation and waste management strategies.
Single-Entity Protein Electrochemistry of Diffusion-Limited Enzymes
Authors: Zhao Ziwen , Kostopoulos Nikolaos , Ganguli Sagar , Bergstrom Paul , Sekretareva Alina
Published: February 2024

Single-entity electrochemistry has recently emerged as a promising method for label-free exploration of the catalytic functions of individual enzymes. However, skepticism within the scientific community regarding the applicability of the method for single enzyme measurements has arisen due to issues in the experimental data presented in the literature and limited theoretical modeling of such data. Here, we address these concerns through a thorough experimental investigation of two diffusion-limited enzymes, catalase and superoxide dismutase, employing a combination of protein film voltammetry and single-entity protein electrochemistry measurements. We then introduce a novel theoretical model for simulating the current responses, generated by the reduction of the product of the enzymatic reaction of single enzyme molecules at the electrode. This model is based on a combination of finite element simulations using COMSOL Multiphysics and random walk simulations. It incorporates the diffusion-limited enzymatic kinetics of the investigated enzymes and introduces a geometry that mimics the substrate diffusion channel of the enzyme. Our work demonstrates that the experimentally detected current signals align with the simulated current signals, affirming that they can be attributed to the catalytic activity of single enzymes detected via the product of the enzymatic reaction.
Ortho Arylation of N-Aryl Amides and the Construction of Diagonal Tetraaryl Anilides via BBr3-Derived Dibromobora-cycles
Authors: Shinde Ganesh , Ghotekar Ganesh , Sundén Henrik
Published: February 2024

In this study, we present a first comprehensive palladium-catalyzed Suzuki–Miyaura C(sp2)-C(sp2) cross-coupling reaction, employing newly derived di-bromo-boracycles as pivotal reagents for the synthesis of ortho arylated N-aryl amides. Our research hinges on the utilization of di-bromo-boracycles, which act as temporary reservoirs of boron, facilitating subsequent transformations in cross-coupling reaction. The di-bromo-boracycle offers a unique opportuni-ty for regioselective carbon-carbon bond formation to the ortho position of N-aryl amides. This mild, site-specific, and scalable protocol is compatible with a wide array of easily accessible functionalized anilides and aryl iodides, as demonstrated by 55 examples, yielding products in the range of 30%-95%. Furthermore, the methodology trans-cends conventional practices, enabling the construction of previously unattainable diagonal aryl systems, highlighting the exceptional potential of our approach for accessing intricate molecular architectures.
An Exercise in Liberal Biblical Theology (Keynote Address)
Authors: Hill Robert Allan
Published: February 2024

This essay was presented at the “Who is my Neighbour? Theological Education in the Global Villiage of the 21st Century” symposium hosted by the McGill School of Religious Studies in the Fall of 2022. It offers an accessible set of reflections on how a liberal biblical theology can help people connect with the content of the Bible in ways that speak to their lived experience, thereby allowing the heart of the Bible to become more familiar and more widely accessible. In modern society, where the letters G-O-D seem like antiquated fiction and where the church has often failed to adequately and meaningfully explicate the Bible in ways that people can connect with, such a sound, gracious liberal biblical theology can be a source of renewal for both Liberal Protestantism and Christian theological education. To demonstrate this I will undertake an exercise in liberal biblical theology, contrasting the traditional Trinitarian language used by G. B. Caird (1951) to explore the unity of the New Testament with more accessible theological language, language arrived at by drawing from the work of Ralph Harper, Samuel Terrien, Dietrich Bonhoeffer, Eric Fromm, Howard Thurman, and Robert Frost.
Onye Agbataobim (My Neighbour) – One Who Finds Refuge in My Heart: On the Significance of Igbo Theological Anthropology for Theological Education in our Time (Keynote Address)
Authors: Atansi Chukwuemeka Anthony
Published: February 2024

In fashioning a response to the question “Who is my neighbour?” – which informs the subject of the symposium on “Theological Education in the Global Village of the 21st Century” – this essay explores the contributions of the Igbo theological anthropology of the neighbour. Igbo theological anthropology considers the neighbour, not simply as one with whom my home shares a boundary, but as one who finds refuge in my heart (onye agbataobim), that is, one with whom there is mutual dependence, vulnerability, and support. This relational understanding of the neighbour in Igbo theological anthropology further derives from the Igbo conception of the human person as “the beauty of life” (mmadụ), and the corresponding attitude of love, “the act of beholding” (ịfunanya), which the sight of, or rather, the encounter with every human person, ought to evoke. The article will outline the significance of these insights for theological education in our time. Such education, the essay argues, ought to take seriously again the fact that there is something irreducibly astonishing about the human person – each and every human being – regardless of geographical boundaries, physical proximity, as well as social, political, and economic connections.

Biosynthesis of silver nanoparticles was accomplished by using 2mM silver nitrate and Moringa oleifera fruit extract by varying the different concentration of aqueous extract. The aqueous extract of moringa oleifera fruit was containing carbohydrates proteins saponins tannins steroids flavonoids amp phenolic phytochemicals. Silver nanoparticles formation with phytochemiclas was confirmed by UV-Vis spectra by observing peak absorption at 409 nm 422 nm amp 426.5 nm. FT-IR spectroscopy showed the capping of silver which was due to polyphenols by observing the peak 1236.42cm-1 as this peak was completely missing in the formulated nanoparticles. Dynamic light scattering of the prepared formulations revealed all the formulations were in nano range Atomic force microscope showed nanoparticles were having smooth surface in the range from 53nm to 70 nm for F4 formulation. X-ray diffraction of the formulation showed the structural information of silver nanoparticle which were face centric cubic FCC in shape. MTT assay of optimized formulation F4 compared with pure aqueous extract showed anticancer activity against A549 cancer cell line with IC50 for aqueous extract was 132.04 mugml were as for synthesized AgNps the IC50 was 110.18 mugml.
Visão Panorâmica do Setor Luxo: Marcas e Grupos
Authors: Minadeo Roberto
Published: February 2024

Objetivo: Aproximar o leitor de uma visão de um conjunto de marcas, aquelas que receberam algum tratamento da Academia. Tais informações foram complementadas por dados de jornais de negócios. Dessa forma, cada marca apresentada possui maior robustez no tocante ao que o leitor pode vir a conhecer.

 

Referencial Teórico: Estudaram-se livros e textos acadêmicos a respeito do setor luxo: importância, crescimento, comportamento do consumidor em relação a tais produtos e valor da marca. Uma linha de pesquisa focada em História Empresarial e ativa há cerca de vinte anos traz informações e dados sobre empresas e organizações dos mais diversos setores. Dessa forma, o projeto de um artigo panorâmico sobre o setor luxo veio amadurecendo até se tornar uma realidade. Foram vistas as trajetórias de marcas e em um segundo momento históricos dos grupos que abrangem diversas marcas e empresas do setor.

 

Metodologia: Apenas foram abordadas no estudo marcas do setor luxo que cumpriram as seguintes condições: a) dados sobre sua trajetória histórica; e b) dados sobre seu volume de negócios. Várias marcas pesquisadas ao longo da linha de pesquisa sobre História Empresarial não puderam ser aqui aproveitadas por não atenderem a tais critérios. Pesquisaram-se textos acadêmicos, dissertações, livros e artigos de atualidade em jornais de negócios – importantes para trazerem dados de atualidade sobre tais marcas e empresas.

 

Resultados: O setor de luxo oferece: a) a possibilidade de formação de grupos com diversas marcas atuando em diversos nichos; b) profissionalização; c) reestruturações bem-sucedidas; e d) rápidos retornos à lucratividade. O setor é de importância tal que seu maior player global tem sido das maiores empresas europeias e seu proprietário disputa a posição de maior riqueza global. Ademais, o setor luxo apresenta grupos de importantes resultados no tocante a receitas e lucros, como se ilustra ao longo do texto. Uma situação inovadora que ilustra o potencial do setor do luxo é quando duas fabricantes de cigarros se fundem e resolvem sair totalmente de seu setor original, tornando-se a maior produtora mundial de joias, além de estar presente em instrumentos de escrita, relógios e outros artigos de luxo.

 

Estudos Futuros: Novos estudos podem focar marcas ou grupos específicos do setor luxo, visando a produção de Estudos de Casos.

 

Originalidade/Valor: A visão panorâmica proporcionada pelo artigo propicia ao leitor se municiar de informes sobre a trajetória empresarial dos maiores grupos empresariais e sobre um significativo grupo de marcas.
BENEFÍCIO DE PRESTAÇÃO CONTINUADA (BPC) E A PROMOÇÃO DO BEM ESTAR SOCIAL DE POPULAÇÕES VULNERÁVEIS NO BRASIL
Authors: Araújo Neto Raul Lopes , Bezerra Franck Sinatra Moura
Published: February 2024

Este artigo disserta sobre o Benefício de Prestação Continuada – BPC, no Brasil, aos olhos das pessoas vulneráveis. Com o desenvolvimento da seguridade trazida pela Constituição de 1988, o legislador criou uma lei para regulamentar aquilo que já estava disposto, surgindo, assim em 1993, a Lei 8.742/93. O BPC trata-se de uma garantia de renda mínima sem condicionalidades e não contributiva, no valor de um salário mínimo, destinada a idosos a partir de 65 anos e pessoas com deficiência em situação de extrema pobreza. Um dos grupos de pessoas vulneráveis que passaram a receber o BPC com urgência e prioridade por parte do poder público, foram as crianças com Microcefalia, atingidas pelo Zika Virus a partir do surto desta doença, especialmente no Nordeste brasileiro em 2015. Após a insegurança e desconhecimento do BPC por parte das famílias com crianças nesta condição, a MP nº 894/2019 instituiu a pensão especial destinada a crianças com microcefalia decorrente do Zika vírus, nascidas entre 2015 e 2018, superando a legislação anterior que lhes mantinham com o BPC por apenas 03 anos. Por fim, o artigo versa sobre o BPC e o Estatuto do Idoso, quando a Lei 10.741 de 01 de outubro de 2003, mais conhecida como Estatuto do Idoso, trouxe diversas questões a serem discutidas no seio da sociedade e implementadas como políticas públicas de proteção à pessoa idosa. O documento legal é hoje um dos mais importantes instrumentos de defesa dos direitos da pessoa idosa. Aprovado em 2003 e vigorando a partir de 2004, o Estatuto do Idoso veio suprir uma carência legislativa a um grupo de pessoas vulneráveis que a cada dia demanda por mais recursos e atenção da sociedade.
ENSAIO A RESPEITO DA FRAGILIDADE DO PLANO DE CUSTEIO DO REGIME PRÓPRIO DE PREVIDÊNCIA SOCIAL DA UNIÃO E A EMINENTE FALÊNCIA DO SISTEMA PROTETIVO.
Authors: Guimarães Stênio Leão
Published: February 2024

O presente trabalho tem por objetivo investigar a respeito da evolução do plano de custeio do Regime Próprio de previdência Social da União e sua efetividade no financiamento de um sistema de proteção sustentável. Busca-se, através de uma pesquisa bibliográfica e normativa, refletir sobre a condução das políticas públicas que definem a participação do custeio dos benefícios previdenciários. Será evidenciado a fragilidade o plano de custeio e a fragilização da base de financiamento através do Regime de previdência complementar. Nesse intento, será indicado que a política de redução do tamanho do Estado visando o controle dos gastos públicos erodirá a base de financiamento do RPPS da União ensejando uma mudança radical na política de custeio a médio prazo. Aponta-se que cabe ao Estado a gerência dos riscos sociais e econômicos no sentido de promover segurança jurídica aos interessados através de controle e planejamento visando a efetividade os objetivos fundamentais da república.
'Norman Laird (1915-1978): Pioneering Tasmanian Filmmaker, Writer and Naturalist'
Authors: Richardson Benjamin
Published: February 2024

Norman Laird was a pioneering Tasmanian advocate for nature conservation through documentary filmmaking and writing in an era before environmental activism was well known, yet his achievements have since been overlooked. Through the camera and pen, Laird was a seminal influence on public discourse about Tasmanian nature in the mid-twentieth century, and, being in the vanguard of environmental thinking, he was at the forefront of the campaign to save Lake Pedder in the early 1970s. His story is particularly fascinating because Laird’s long career with the Tasmanian Government Film Unit potentially conflicted him in making government-sponsored cinema that celebrated hydro-dams, forestry and other environmentally impactful activities. How Laird navigated that tension and how the Film Unit itself evolved amidst the environmental activism of the 1970s provokes wider reflections on the role of environmental documentaries in mediating social change.
