Linguistic threat: Vote choice, linguistic cues and support for official bilingualism in Quebec

AbstractIn Canada, federal institutions must provide governmental services to all citizens in the country's two official languages: French and English. This paper uses a survey experiment to test exposure to written English as a determinant of support for official bilingualism in the French‐speaking province of Quebec. The data emanate from an exit poll conducted in two Quebec electoral districts during the 2019 Canadian federal elections (n = 430). Results suggest the existence of heterogeneous experimental effects depending on vote choice. Indeed, Bloc Québécois voters—the federal party most strongly supportive of linguistic rights—are disproportionately supportive of institutional bilingualism when randomly exposed to written English on the survey questionnaire. These results are robust to the inclusion of socio‐demographic and attitudinal control variables, including support for Quebec independence. Our paper bolsters causal claims about the contextual determinants of in‐group favouritism and cultural threat in divided societies.

Germany's national public health gets reorganized: A new institute shall take center stage

In the aftermath of the COVID-19 pandemic, the German federal government recently orchestrated a fundamental change to its public health infrastructure. This reconstruction centers around the founding of a National Institute for Prevention and Education in Medicine (Bundesinstitut für Prävention und Aufklärung in der Medizin, BIPAM) at the cost of two federal institutions, the Robert Koch-Institute (RKI) and the Federal Center for Health Education (Bundeszentrale für gesundheitliche Aufklärung, BzGA). Thus, the Federal Ministry of Health (Bundesministerium für Gesundheit, BMG) plans to dissolve the BzGA and integrate its personnel into the future BIPAM. Further, all RKI research and surveillance activities related to non-communicable diseases, including AI methods development will be transferred into the BIPAM. The RKI responsibilities will solely focus on infectious diseases. According to announced plans of the BMG the primary objective for establishing the BIPAM is to address non-communicable diseases and enhance overall population health. However, the medical specialist training for public health remains non-academic at a state institution. Simultaneously the BMG already replaced two thirds of experts of the permanent commission on vaccination (Ständige Impfkommission, STIKO) and determined new procedures for appointing future expert commissioners. With these changes, Germany embarks on an extraordinary reshuffling of its national public health organizations and responsibilities, by fundamentally separating all issues around non-communicable diseases from those of infectious diseases. Germany's unraveled research tasks of public health authorities however remains unmet. Thus, 2024 marks a pivotal caesura for public health in the modern history of Germany.

Exploration of hydrothermal venting sites using deep-towed multibeam echosounder data

The Federal Institute for Geosciences and Natural Resources (BGR) obtained a contract for the exploration of polymetallic sulphides from the International Seabed Authority (ISA) in an area of 10,000 km2 located in the southwestern Indian Ocean. Since obtaining this contract of exploration in 2015, BGR has conducted annual research cruises to this area and continuously improves the exploration methods for seafloor sulphides deposits. One of the main instruments is HOMESIDE, a deep-towed multibeam echo sounder (MBES) sled. Its water column data allows to visualize and therefore locate discharge sites of hydrothermal fluid – active hydrothermal venting sites (or commonly also referred to as “black smokers”). Additionally, its bathymetric data is used for geological mapping and therefore greater analysis of the seafloor geomorphology. HOMESIDE is typically towed at an altitude of about 100 m above the seabed in a water depth of approximately 3,000 m, allowing a resolution of the derived digital terrain model (DTM) of 2 m. Due to malfunction of individual positioning sensors or operational errors, the navigation data might need to be further corrected in post-processing. Navigation offsets between adjacent lines are mostly apparent in overlapping swath data. The tool mbnavadjust of the open-source software MB-System showed to be a valuable tool to improve the data quality subsequently in areas with data overlap and systematic navigation offsets. Data mismatches of more than 10 m are processed with this tool and can, therefore, be reduced significantly. In this paper, firstly, the role of deep-towed MBES as exploration tool for hydrothermal sites is presented. Secondly, the importance of post-processing MBES navigation based on the swath data especially for this project is highlighted. The workflow as well as the results are presented and show significant improvement.

Determination of Relationship Between the Application of ICT and Decision-Making Federal Universities of Northern Nigeria

This study examines how Federal Universities of Northern Nigeria use ICT to make decisions. Technology in data storage, analytics, and decision support systems has transformed decision-making, according to the introduction. We examine how ICT improves decision-making through data gathering, analysis, and communication. The hypothesis is that ICT use does not affect decision-making in these universities. The correlational study included 2,114 workers from all Northern Nigerian Federal Universities. The sample procedure selected states from each geopolitical zone and seven federal institutions from each state. Data was collected using a questionnaire on ICT in Effective Planning (QAICTEP). The null hypothesis was tested using Pearson's Product Moment Correlation coefficient (PPMCC). The respondents' age, experience, and qualifications were diverse. Male respondents outnumbered female respondents 75% to 25%. The null hypothesis was rejected since the PPMCC analysis showed a positive correlation (r = 0.609) between ICT application and decision-making. The conclusion shows that ICT use improves decision-making. ICT infrastructure investments, training, enhanced Decision Support System integration, and strong data governance regulations are recommended. at conclusion, this study sheds light on strategic ICT integration and decision-making at Federal Universities in Northern Nigeria, emphasising the need to improve decision-making quality and efficiency.

Reverse logistics and sustainability: the case of the Federal Institute of Acre, Brazil

The implementation of sustainable practices in the educational context is fundamental to foster a culture of environmental and social responsibility. This study investigates reverse logistics practices at the Rio Branco Campus of the Federal Institute of Acre (IFAC), aiming to identify implemented actions, challenges faced, and propose strategies to strengthen the institutional commitment to sustainability. Using a mixed-method approach, we combined documentary analysis of the internal regulations and the Institutional Development Plan (IDP) with semi-structured interviews with members of the academic community. The documentary analysis revealed institutional alignment with sustainable practices, evidenced by environmental and social responsibility goals in IFAC's IDP. However, the lack of specific guidelines for post-consumer reverse logistics suggests the need for improvement. Interviews highlighted employees' awareness of sustainability and reverse logistics as positive, but pointed to the lack of clear guidelines as a gap. Although the Rio Branco Campus of IFAC demonstrates a commitment to sustainability, there is room for improvement in integrating post-consumer reverse logistics practices. We recommend the inclusion of specific goals and strategies for solid waste management in the IDP, as well as a more comprehensive approach to sustainability in institutional policies. These final considerations establish a basis for future research and practical improvements, aiming to strengthen the institutional commitment to sustainability at IFAC.

Profiles of mental illness in college students and associated factors: A latent class analysis

Mental illness among university students poses a pressing challenge for educational institutions, urging the need for strategies that foster health and mitigate mental distress, with an emphasis on preventing suicide. Our study sought to discern the profiles of mental illness among college students and explore the factors associated with them. We examined data from 918 students at a Brazilian Federal Institute, utilizing Latent Class Analysis and multinomial regression for our analyses. We identified three distinct mental illness profiles: Anxiety with Low Suicide Risk; Mental Illness with Moderate Suicide Risk; and Mental Illness with High Suicide Risk. We observed a reduced association of these profiles with religious beliefs. Conversely, there was a heightened association with cisgender women, individuals identifying as LGBTQI+, those with learning disabilities, and victims of sexual violence. Our findings underscore the importance of tailored prevention and health promotion programs to enhance student well-being. There's a compelling need to devise mental health strategies tailored to the specific needs of the identified groups, particularly students from the LGBTQI + community, survivors of sexual abuse, and those grappling with learning disabilities.

Preservation of Intangible Ethnocultural Heritage in the Electronic Environment

The article considers the issues of preserving and updating the ethnocultural heritage of the peoples of the Russian Federation within the framework of the activities of museums, houses of folk art, higher educational institutions, academic research institutes. Institutions for which the preservation of cultural heritage is not the main essential activity, but has recently been actively developing, are characterized. These are federal and national universities and research institutes of the Russian academy of sciences. Universities integrate successfully knowledge related to intangible cultural heritage into educational programs. Research institutes have become reference bases in their regions in the study and preservation of national languages as objects of intangible cultural heritage, national literature and ethnography. The prospects for such activities of libraries are considered, a new role of which is given in the Federal Law N 402-FL “On the intangible ethnocultural property of the Russian Federation”. The possibility of digitizing and forming digital collections of objects of intangible cultural heritage recorded in the form of texts and static images in libraries, as well as information objects existing in the form of temporary representation (recording of musical works, dances, folklore) has been identified. Particular attention in digitization in libraries should be paid to funds on national languages, collections of audio recordings of folk music and ethnographic collections. Examples of the practice of presenting intangible ethnocultural heritage on federal and regional portals/sites are given.

EXAMINING PRESIDENTIAL IMMUNITY: THE JANUARY 6 RIOT, TRUMP, AND THE 14TH AMENDMENT - AN IMPERATIVE CONSIDERATION OF CONSTITUTIONAL LAW

The work critically engulfs the events surrounding the January 6 riot, interactions, Trump’s alleged involvement, and the application of the 14th Amendment’s Section 3. The central question of the study puzzles on whether the said Amendment grants States jurisprudence to determine or alter presidential immunity. Drawing on Montesquieu's theory of separation of powers - a natural pillar of Federalism that was fundamental in drafting the US Constitution, the work embarks on an exploration that investigates the intersections of States prerogatives on Federal institutions. Building on these constructions, the work delves into intricate legal debates interlocking constitutional interpretation, and emphasizing its potential ramifications. The study employs comparative methodology; incorporating the ten Southern-States that barred Abraham Lincoln, and the case of USA vs Nixon. The approach illuminates political materialism, an enduring theme in American politics, thus, producing a better understanding of the state of the art, through the intrinsic corollaries of federalism in the ever evolving extensive milieus of political constitutionalism and legal canons.

Substantiation. The article presents the structure and medical and social aspects of the primary disablement of the adult population of the Altai Region due to schizophrenia for the period from 2015 to 2019. Purpose of the study: to investigate the structure of primary disablement of the adult population of the Altai Region due to schizophrenia (by sex, age, place of residence, the main types, and degree of impairment of body functions and life limitations) and present the medical and social characteristics of patients first recognized as disabled. Material and methods. During the study, statistical data of the Federal State Institution «Main Bureau of Medical and Social Expert Examination for the Altai Region» of the Ministry of Labor and Social Protection of the Russian Federation were used. The material of the study included reporting forms No. 7‑sobes (n=5), protocols for conducting medical and social expert examination in the federal state institution of medical and social expert examination (n=745), and forms No. 088 / u of medical organizations (n=745). The research period was 2015‑2019. Research methods: documentary, data copying, statistical, and analytical methods. Results. The study has indicated that in the structure of primary disablement of the adult population of the Altai Region due to schizophrenia, urban residents predominate, while men prevail in the gender category. More than 90.0 % of the patients first recognized as disabled due to schizophrenia are citizens of working age. The vast majority of the patients did not work at the time of examination, while having a professional education. More than half of the patients,mostly men, were not married, had no children, and lived with their parents. In more than 90.0 % of the patients, the paranoid type of schizophrenia led to disability, and the main maladapting syndrome involved emotional and volitional disorders. More than 60.0 % of the patients had persistent moderate impairment of body functions; life limitations were more frequently detected in the following categories: the ability to work, the ability to communicate, and the ability to control one»s behavior. More often, patients with schizophrenia obtained the third group of disability during the initial examination. Conclusion. The results of the study can be a scientific and practical basis for planning and effective implementation of comprehensive rehabilitation of disabled patients with this pathology.

Driving transformation in higher education: Exploring the process and impact of educational innovations for sustainability through interdisciplinary studies

AbstractIn recent years, there has been a growing focus on innovation research, particularly in the manufacturing and information technology sectors in the US and Europe. However, the disruptions caused by the recent pandemic called for more innovations, especially in the education industry. Innovation is viewed as an outcome of a set of various drivers. This study explored faculty perspectives on the drivers of innovation that can transform the curriculum into an interdisciplinary model to promote sustainability in education. Additionally, it examined the relationship between these drivers and the outcome of innovation, particularly at the process level. An explanatory sequential mixed‐method approach was employed to collect quantitative and qualitative data from a purposeful sample of 60 faculty members at one federal higher education institution in the United Arab Emirates. Findings indicated that while there is a correlation between the drivers and process of innovation and sustainability in education, other factors played a more significant role in facilitating this transformation. Empowering faculty members and involving them in the process of transformation, connecting them with the institutional vision and mission for innovation, fostering a clear understanding of the value of the transformation, providing faculty with continuous professional learning and development opportunities to promote the use of innovative pedagogical methods, are among the key factors.

Labor inclusion of deaf individuals: the education/work relationship

Many discussions have brought up the issue of Special/Inclusive Education as an essential factor for people with disabilities. However, after the educational period, a question is important to ask about the lives of these social actors. Survival is crucial and perhaps some will start to live off the charity of others or the state. It is believed that the insertion into the job market is also crucial for them to have autonomy and more independence. Therefore, this research presents the scenario of labor inclusion of deaf people, seeking to understand the education/work relationship. The primary objective of this article is to analyze the proportion of influence of the educational process on the inclusion of deaf people in the formal job market in São Luís/MA. Data were collected through semi-structured interviews in the city of São Luís/MA, with four deaf participants, formally linked to federal spheres and private companies, in the following federal public institutions: the Federal University of Maranhão (UFMA) and the National Institute of Social Security (INSS) and two private companies in the retail sector. The results showed that education strongly influences the inclusion of deaf people in the job market. Therefore, access to higher education is a big step towards seeking vacancies in public positions, with better salaries, while a process interrupted in secondary education could allow for more exhaustive jobs in private companies that hire deaf people just to comply with what the quotas law recommends.

Reckoning with Colonial Legacies of Harm: Victoria’s Yoorrook Justice Commission

ABSTRACT Australia’s colonial era is formally over. Yet the legacies of structural inequality, dispossession, exploitation and racism against Indigenous Australia remain alive and well. In 2021, Victoria established the Yoorrook Justice Commission, culminating in a formal truth-telling and treaty process. Seeking to address harm since colonization, the state process is unprecedented both nationally and abroad. This article considers the relevance of the commission to truth recovery, accountability and structural reform in Australia. To date, national efforts to deal with the colonial past have been piecemeal and relatively ineffective. The Yoorrook Justice Commission departs from previous single-issue inquiries as well as from reconciliation policies driven by white-Australian federal institutions. While the Commission is not a panacea for resolving colonial injustice, it provides an important means of relational and structural truth-telling towards more just relations and righting racial wrongs. Ultimately, the Yoorrook Justice Commission sets a valuable precedent for Australia and other postcolonial nations. Its level of Indigenous ownership, its authority as a Royal Commission and the breadth of its inquiry make it a significant transitional justice project.

Determinants of Academic Satisfaction: An Empirical Analysis of a Brazilian National Institute

Objective: The present investigation aims to identify the explanatory factors for academic satisfaction, as well as the influence that the identified factors have on the degree of academic satisfaction in its global context and on the chances of the institution's recommendation to friends and family. Method: The investigation was conducted with a sample of 290 students from the Federal Institute of Education, Science, and Technology of Piauí (FIEPI-Campus Oeiras). The instrument used for data collection was a questionnaire. The statistical techniques used were of a descriptive, exploratory, and multivariate nature for the treatment, analysis, and validation of the results. Results and Discussion: The results indicate that Academic Satisfaction is determined by the factors (1) Teaching Environment and (2) Structural Environment and that there is a significant decrease in Academic Satisfaction when students move from the group from High School to Higher Education due to the determinants satisfaction. Research Implications: The development of strategies for the maintenance and attraction of new students by FIEPI-Campus Oeiras and other educational institutions must be based on academic satisfaction considering their specificities, namely, concerning the different perceptions and expectations generated by students about educational services. Originality/Value: The relevance of this investigation is based on the fact that the measurement of student satisfaction by a given educational institution becomes essential for it to understand the perception of its students about its products and services, enabling the identification of new ways of generating satisfaction and loyalty.

Predictive value of a novel digital risk calculator to determine early patient outcomes after major surgery: a proof-of-concept pilot study

BackgroundA structured risk assessment of patients with validated and evidence-based tools can help to identify modifiable factors before major surgeries. The Protego Maxima trial investigated the value of a new digitized risk assessment tool that combines tools which can be easily used and implemented in the clinical workflow by doctors and qualified medical staff. The hypothesis was that the structured assessment and risk-grouping is predictive of short-term surgical quality reflected by complications and overall survival.MethodsThe Protego Maxima Trial was a prospective cohort analysis of patients undergoing major surgery (visceral, thoracic, urology, vascular and gynecologic surgeries) as key inclusion criterion and the absence of an acute or acute on chronically decompensated pulmo-cardiovascular decompensation. Patients were risk-scored with the software (The Prehab App) that includes a battery of evidence-based risk assessment tools that allow a structured risk assessment. The data were grouped to predefined high and low risk groups and aggregate and individual scores. The primary outcome was to validate the predictive value of the RAI score and the TUG for overall survival in the high and low risk groups. Secondary outcomes were surgical outcomes at 90-days after surgery (overall survival, Clavien-Dindo (CD) 1–5 (all complications), and CD 3–5 (major complications)). The study was carried out in accordance with the DIN ISO 14,155, and the medical device regulation (MDR) at Frankfurt University Hospital between March 2022 and January 2023.ResultsIn total 267 patients were included in the intention to treat analysis. The mean age was 62.1 ± 12.4 years. Patients with a RAI score > 25 and/or a timed up and go (TUG) > 8 s had a higher risk for mortality at 90 days after surgery. The low-risk group predicted beneficial outcome and the high-risk group predicted adverse outcome in the ROC analysis (Area Under the Curve Receiver Operator Characteristics: AUROC > 0.800; p = 0.01). Risk groups (high vs. low) showed significant differences for 90-day survival (99.4% vs. 95.5%; p = 0.04) and major complications (16.4% vs. 32.4%; p < 0.001).ConclusionThe proof-of-concept trial showed that a risk assessment with ‘The Prehab App’ may be viable to estimate the preoperative risk for mortality and major complications before major surgeries. The overall performance in this initial set of data indicated a certain reliability of the scoring and risk grouping, especially of the RAI score and the TUG. A larger data set will be required to proof the generalizability of the risk scoring to every subgroup and may be fostered by artificial intelligence approaches.Trial registrationEthics number: 2021-483-MDR/MPDG-zuständig monocentric; The Federal Institute for Pharmaceuticals and Medical Devices/BfArM, reference number: 94.1.04-5660-13655; Eudamed: CIV-21-07-0307311; German Clinical Trial Registry: DRKS 00026985.

Quechers Extraction Followed by HPLC Estimation of Steroidal Glycoalkaloids viz, α-Chaconine and α-Solanine in Different Solanaceae Family Vegetable Varieties

Glycoalkaloids are the alkaloid derived chemical constituents naturally produced in various plants species especially Solanaceae family. These chemical constituents protect the plant against predators as well as pathogens. The consumption of high dose of glycoalkaloids was toxic to humans. This study was purposeful to evaluate steroidal glycoalkaloids viz., α-chaconine and α-solanine quantity in different Solanaceae family vegetable varieties. The QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) extraction using acetonitrile as extracting solvent was used for extracting steroidal glycoalkaloids in vegetable samples. In the optimized conditions, the standard chromatogram shows clear resolution of α-chaconine and α-solanine. The analytes were identified at 3.15 min for α-chaconine and 4.88 min for α-solanine. The optimized HPLC (High pressure liquid chromatography) method was validated. The method optimized using acetonitrile and 1.0 mM ammonium acetate buffer at pH 4.2 in 65:45 (v/v) as mobile phase at 0.6 mL/min, μBondapak C18 (10 μm, 4.6x250 mm) column as stationary phase and UV detection is selected at 218 nm. Findings suggest that this method was simple and convenient for the estimation of glycoalkaloids in vegetables. The glycoalkaloids was achieved under the acceptable levels of less than 200 mg/kg as prescribed by USFDA and German Federal Institute for Risk Assessment.

HIV status of individuals who underwent pre-employment medical screening at a federal tertiary health institution in southeast Nigeria

Background: The human immunodeficiency virus (HIV) targets the host immune system, particularly the CD4 T cells. The host resistance to opportunistic and non-opportunistic infections such as tuberculosis, fungal infections, severe bacterial infections, and several malignancies is weakened as a result of destruction of these CD4 cells by HIV. The purpose of this study was to determine the prevalence of HIV among individuals who participated in pre-employment medical screening at David Umahi Federal University Teaching Hospital Uburu, Ebonyi State, Nigeria, with the aim of connecting those who are HIV-positive to voluntary counseling and treatment programs.&#x0D; Methodology: This was a retrospective analysis of the medical records of 537 eligible participants who underwent pre-employment medical screening exercise, and whose blood samples were tested for presence of HIV antibodies at the University Teaching Hospital, using the Determine HIV-1/2 (T1) and Unigold HIV-1/2 (T2), and the tie breaker Statpak HIV-1/2 (T3) tests. The serological results were interpreted according to the national HIV testing algorithm, with test result declared negative for HIV antibodies if T1 was negative or if only T1 was positive but T2 and T3 were both negative.&#x0D; Results: Of the total record of 756 pre-employment participants for the medical screening exercise, only 537 met the inclusion criteria for the study. The mean age of the 537 participants was 34.2±6.9 and age range of 18-67 years; 325 (61.0%) were females while 212 (39.0%) were males. The seroprevalence of HIV among the study participants was 2.4% (13/537), with 1.4% (3/212) in the males and 3.1% (10/325) in the females (x2=0.879, OR=0.45; 95% CI=0.12-1.60, p=0.3485). Only participants in the age range 26–35 and 36–45 years were HIV seropositive, with prevalence of 2.9% (9/310) and 2.4% (4/169) respectively but the HIV seroprevalence was not significantly associated with age and gender of the participants (p&gt;0.05).&#x0D; Conclusion: The study findings provide useful information for the hospital administration of the HIV situation of its planned workforce, which will help with decisions on HIV positive participants to enrol in antiretroviral therapy program.&#x0D; Contexte: Le virus de l'immunodéficience humaine (VIH) cible le système immunitaire de l'hôte, en particulier les lymphocytes T CD4. La résistance de l'hôte aux infections opportunistes et non opportunistes telles que la tuberculose, les infections fongiques, les infections bactériennes graves et plusieurs tumeurs malignes est affaiblie en raison de la destruction de ces cellules CD4 par le VIH. Le but de cette étude était de déterminer la prévalence du VIH chez les personnes ayant participé à un dépistage médical préalable à l'emploi à l'hôpital universitaire fédéral David Umahi d'Uburu, dans l'État d'Ebonyi, au Nigeria, dans le but de connecter les personnes séropositives à des conseils volontaires et des programmes de traitement.&#x0D; Méthodologie: Il s'agissait d'une analyse rétrospective des dossiers médicaux de 537 participants éligibles qui ont subi un exercice de dépistage médical préalable à l'emploi et dont les échantillons de sang ont été testés pour la présence d'anticorps anti-VIH à l'hôpital universitaire, à l'aide du système de détermination du VIH-1/2 (T1) et Unigold HIV-1/2 (T2), ainsi que les tests de départage Statpak HIV-1/2 (T3). Les résultats sérologiques ont été interprétés selon l'algorithme national de dépistage du VIH, le résultat du test étant déclaré négatif pour les anticorps anti-VIH si T1 était négatif ou si seul T1 était positif mais que T2 et T3 étaient tous deux négatifs.&#x0D; Résultats: Sur le total de 756 participants préalables à l'emploi pour l'exercice de sélection médicale, seuls 537 répondaient aux critères d'inclusion de l'étude. L'âge moyen des 537 participants était de 34,2±6,9 ans et la tranche d'âge était de 18 à 67 ans; 325 (61,0%) étaient des femmes tandis que 212 (39,0%) étaient des hommes. La séroprévalence du VIH parmi les participants à l'étude était de 2,4% (13/537), dont 1,4% (3/212) chez les hommes et 3,1% (10/325) chez les femmes (x2=0,879; OR=0,45; 95% IC=0,12-1,60; p=0,3485). Seuls les participants âgés de 26 à 35 ans et de 36 à 45 ans étaient séropositifs au VIH, avec une prévalence de 2,9% (9/310) et 2,4% (4/169) respectivement, mais la séroprévalence du VIH n'était pas significativement associée à l'âge et au sexe des personnes les participants (p&gt;0,05).&#x0D; Conclusion: Les résultats de l'étude fournissent des informations utiles à l'administration hospitalière sur la situation VIH de sa main-d'oeuvre prévue, ce qui aidera à prendre des décisions concernant les participants séropositifs à s'inscrire à un programme de thérapie antirétrovirale.
