PERCEIVED SOCIAL SUPPORT AND JOB PERFOR-MANCE OF LAW ENFORCERS IN MALITA
Authors: Tabernero Kenny James R. , Español Jay D. , Tindoy Mariane Claire G.
Published: July 2024

This study determined the perceived social support and job performance of law enforcers in Malita. Descriptive - correlational research design was used in this study. Data were gath-ered using adopted survey questionnaires and tallied and tabulated with the aid of statisti-cal software. The statistical tools used to interpret the data are mean, standard deviation, Spearman’s rank-order correlation analysis, and stepwise multiple regression analysis. Results of the study showed that the perceived social support of the law enforcement per-sonnel in terms of significant others, family and friends is described as “high” which means that social support towards law enforcement personnel is always manifested. The job performance of law enforcers across all domains is described as “excellent”. This im-plies that the law enforcers have distinguished job performance. Therefore, we reject the null hypothesis and conclude that there is a significant relationship between perceived social support and the job performance of the law enforcers. Furthermore, the friends' construct was considered the best predictor of the dependent variable, job performance.

Published: July 2024

Conducting experiments with microorganisms is usually quite laborious, as it requires appropriate techniques and a suitable laboratory environment, particularly when looking for possible microorganisms resistant to the main antimicrobials available against bacteria and fungi. Since the nineteenth century, it has become evident that microorganisms are living beings that are impossible to be visualized without the aid of optical microscopes, since bacteria measure 1μm, viruses 1nm. Although fungi are around 100μm in diameter, the visualization of microscopic forms, yeasts require care. However, regardless of size, microorganisms are ubiquitous, found in the most diverse ecosystems. They are fundamental in the decomposition or recycling of organic matter, especially in the early stages.
Gênero, sexualidade e trabalho: Heteronormatividade e o assédio moral contra homossexuais no contexto organizacional
Authors: Lima Lucas Alves de Oliveira , Filho Teodoro Antunes Gomes
Published: July 2024

O objetivo desta pesquisa foi analisar a associação entre a heteronormatividade e assédio moral contra homossexuais no contexto organizacional. Utilizando a metodologia de revisão integrativa de literatura, foram consultadas bases de dados como SciELO, Web of Science, Scopus e Google Acadêmico. Durante a busca, foram utilizadas palavras-chave específicas em associação com descritores de busca AND e OR, de modo a selecionar somente artigos brasileiros, em português, gratuitos, disponíveis por completo e publicados entre os anos de 2016 e 2021. Como resultado, constatou-se que os profissionais homossexuais enfrentam formas agravadas de assédio moral, refletindo preconceitos arraigados baseados em concepções morais e sociais distorcidas. Assim como as mulheres historicamente relegadas a papéis secundários, minorias sexuais frequentemente sofrem insultos e discriminação no ambiente de trabalho devido à sua orientação sexual. A heteronormatividade, que estabelece a heterossexualidade como norma dominante, perpetua estereótipos prejudiciais e cria um ambiente propício para o surgimento e perpetuação do assédio moral contra indivíduos LGBT+. Como consequência, a pressão para conformidade aos padrões heterossexuais predominantes pode resultar na ocultação da identidade sexual no trabalho, como estratégia para evitar discriminação ou exclusão. Além disso, a falta de conscientização e educação sobre diversidade sexual contribui para uma cultura organizacional que não facilita o diálogo aberto e respeitoso sobre essas questões. Assim, destaca-se a necessidade de políticas organizacionais mais inclusivas e educativas, visando mitigar o assédio moral e promover ambientes de trabalho respeitosos e diversificados. Conclui-se que enfrentar a heteronormatividade não apenas protege os direitos dos profissionais LGBT+, mas também fortalece a cultura organizacional e contribui para o bem-estar e a equidade dentro das organizações.

Published: July 2024

Women in uniformed professions, including firefighters, are at high risk of being victims of institutional discrimination and sexual harassment. The aim is to describe the occupational, social, and psycho-emotional experience of female firefighters in Chile in situations of discrimination and harassment in the organization and formulate guidelines for creating institutional gender policies. Data collection was carried out through three focus groups. Eleven female firefighters participated. The information obtained was analyzed through content analysis, forming four themes. Difficulties were identified in women doing their jobs as firefighters. Simultaneously, the presence of situations of gender discrimination and institutional sexual harassment were identified, which causes emotional exhaustion in female firefighters. Our results highlight the need for effective implementation and dissemination of institutional policies that protect female workers from abusive situations. Guidelines are proposed for the development of such institutional policies.

Published: July 2024

Metallic materials in granular packings show different electrical properties from their bulk counterparts. In this paper, we investigate the temporal evolution of the electrical conductivity of granular metals. We use metallic beads arranged in different one-, two- and three-dimensional ensembles through which different constant currents are injected. The conductivity behavior in all three types of systems is qualitatively similar. The results show the rise of conductivity which is more pronounced in the earlier stages of the time evolution. We investigate the influence of the dimensionality, number of the beads, and the values of the injected currents on the conductivity behavior.

Authors: Halilović Jasmin , Nasić Edis , Mujagić Derviš
Published: July 2024

This study investigated the mechanical properties of a series of Fe-Cr-Mn (Mo)-N alloys. The chromium content ranged from 16 to 18 mass %. The test alloys were produced by adding nitrided ferroalloys during melting in an induction furnace. Test specimens of each alloy were prepared for mechanical testing and microstructural observation. Tensile strength (TS) and elongation (EL) were determined. By increasing or decreasing the content of the chromium, it can directly affected on the values of the mechanical properties and the final microstructure. A series of experiments showed that increasing the chromium content by 1.46 mass% in the Fe-16Cr-8Mn (Mo)-N alloy led to a decrease in the TS value by 12% and in the EL value by 16.1%, while increasing the chromium content by 0.72 mass% in the Fe-16Cr-11Mn (Mo)-N alloy caused a decrease in the TS value by 6.1% and in the EL value by 16%. The chromium content of 16 mass % in the studied alloys was found to provide sufficient strength and a relatively high elongation value. The alloys can also contain a higher mass fraction of chromium, but to obtain a complete austenitic structure it is necessary to increase the content of manganese and nitrogen.

Published: July 2024

Steel 17-7PH is austenitic-martensitic steel with high strength, hardness, and resistance to creep, and corrosion. It is designed for aerospace components, but can also be used for other applications that require high strength and corrosion resistance, as well as leaf springs for operation at temperatures up to 316 °C. It can be used in a solution-treated or heat-treated state to obtain a wide range of property values. This paperwork shows that modification of the contents of alloying elements with a narrower interval of Cr, Ni, and Al can be obtained from austenitic-martensitic steel 17-7PH which by, a subsequent heat treatment, can have values of mechanical and chemical properties required for components of an automotive engine. Chromium is an alphagenic alloying element that stabilizes the ferrite region, nickel is a gammagenic alloying element that stabilizes austenite and gives these steels good strength and toughness, even at low temperatures and aluminum increases corrosion resistance in low-carbon corrosion-resistant steels Research has determined the most suitable interval of Cr, Ni, and Al, which in combination with the
cryogenic heat treatment RH950 at -50 °C gives the mechanical and chemical properties that meet the requirements for steel with standard chemical composition.

This study aims to test the impact of students' entrepreneurial self-efficacy on their ability to recognize opportunities after attending entrepreneurship education in the classroom, which leads to the development of intention to carry out entrepreneurial activities. A detailed questionnaire was used to collect data from 94 students pursuing undergraduate programs at the Sekolah Tinggi Manajemen Labora. The results confirm that students' entrepreneurial self-efficacy positively affects their intention to carry out entrepreneurial activities directly. In addition, entrepreneurship education does not significantly moderate the relationship between students' entrepreneurial self-efficacy and opportunity recognition ability.
Representações Implícitas Probabilísticas de Grafos
Authors: Lopes Juan P. A. , Oliveira Fabiano de S. , Pinto Paulo E. D.
Published: July 2024

This paper introduces the concept of probabilistic implicit graph representations, extending the definition from [Spinrad 2003] by allowing the adjacency test to have a constant probability of false positives or false negatives. It also discusses two novel representations based on well-known probabilistic data structures: one that uses Bloom filters and can represent general graphs with the same space complexity as the adjacency matrix (but outperforms it for sparse graphs), and other that uses MinHash and can represent trees with lower space complexity than any deterministic implicit representation.

The Quest for Meaningful Special Education
Authors: Ballin Amy
Published: July 2024

Every child should have access to an education that works. The Quest for a Meaningful Special Education follows the educational journeys of nine students with a language-based learning disability (LBLD) who, through a combination of parental advocacy and luck, were removed from a debilitating learning situation and enrolled in a school designed to address their particular learning needs. In the process of following their journeys, the book explores the role of cultures within and outside the school and examines some of the ways that the construction of special education has affected student learning.

In the context of the ongoing national conversation about student academic success, high school dropout rates, the disproportionate number of prison inmates with learning disabilities, the costs of educating students, and the controversy over the placement of minorities in special education, The Quest For a Meaningful Special Education is a timely book that will add a new perspective to current debates

Raising an Active Reader
Authors: Cleaver Samantha
Published: July 2024

"This book will prove a valuable resource for parents, teachers, and librarians on the vital topic of reading aloud." Library Journal, Starred Review

Parents and teachers know that reading aloud to children is important, and many parents of infants and toddlers read aloud to them daily. However, when children start to read on their own, parents often stop reading aloud. But these early elementary school years are actually a perfect time to build vocabulary and comprehension skills through reading aloud and Active Reading.

Raising an Active Reader makes clear the process of learning to read, how Active Reading fits into raising strong readers, and what adults can do to encourage strong language, comprehension, and vocabulary in children in grades K-3. This book extends on the ABCs of Active Reading (Ask Questions, Build Vocabulary, and make Connections) as they apply to older children for picture books, chapter books, and novels. It provides parents and teachers with examples, clear explanations, and ideas for making one-on-one or small group read aloud sessions a powerful way to build children’s early literacy and language skills, all while creating a lifelong love of reading.

Leadership for Inclusive Schools
Authors: Sider Steven Ray , Maich Kimberly

This book supports the professional learning of school principals, and those who aspire to be such, in development of their skills and knowledge around fostering inclusive schools for students with special education needs. The book includes 27 case stories that are based on research with school principals. Each case includes expert commentaries and resources to support principals and emerging leaders as they consider how to effectively support students with special education needs in inclusive schools. Its premise is based on the recognition that there are increasing numbers of students with disabilities and special education needs in neighbourhood schools. Principals need to develop new competencies to navigate the challenges, and benefits, of including students with special education needs into inclusive classroom settings. The book provides opportunities to build leadership competencies by considering a diversity of cases related to inclusive leadership. The cases in the book are divided among nine sections addressing the following areas: transitions, early years, elementary school cases, secondary school cases, community supports, school board/district supports, school teams, complex cases, and cases specific to new teachers. Seven cross-cutting themes are addressed in these cases including: communication, parents/caregivers, agency/efficacy, collaboration, relationships/trust, legal, and advocacy.
Maximum Impact
Authors: Creasman Brian K. , Hughes Brad
Published: July 2024

Maximum Impact is an affirmation of the importance of communication by America’s local boards of education and superintendents. The book is based on principles developed in our professional roles as authors, a district superintendent, educational researcher, broadcast journalist, public affairs and social media director and government spokesperson. Each chapter - highlighting critical aspects of team communication by boards of education and the superintendent - is grounded in our work and experience. Our belief in communication as a tool for district transformation leads us to focus on dynamics between school leaders and the need to deploy a strategic communication strategy, a first book in today’s literature. We endeavor to help boards of education and superintendents - aspiring, novice or veteran – to recognize the vital nature of communication in the governance and leadership of public education, now and in the future. With the call for more transparency in government, including public education, we offer our primary target audience of school leaders with new principles of communication that will help them to engage the community, employees and stakeholders in helping to make their school district successful!
