Geographical disparities in gastroenterologists and transient elastography across Canada
Authors: Burnside Jessica , Thomas Tyler , Sebastiani Giada , Saeed Sahar
Published: October 2023

Background:

In the next decade, the incidence and prevalence of advanced liver disease are expected to increase across Canada. However, little is known about the country’s resources for monitoring patients requiring specialized care. A resource assessment was conducted to evaluate regional disparities of specialists and transient elastography machines across Canada.

Methods:

Demographic data on licenced gastroenterologists were obtained from Scott’s Medical Directory as of October 2022. The primary location of each specialist was linked to 2016 Statistics Canada to obtain the population size and density of provinces/territories and census division (CD). Results were summarized per 100,000 persons. CDs were classified as resource scare or approaching resource scarcity. A list of transient elastography (TE) was provided by KNS Canada Inc. and summarized per 1,000,000 persons by province.

Results:

Eight hundred fifty-three specialists were identified. Rates of gastroenterologists per 100,000 people ranged from 0 in the territories to 2.9 in Quebec. Half the provinces had fewer than 2.0 gastroenterologists per 100,000 persons. Gastroenterologists were concentrated in 24% (71/293) of the CDs across Canada. We identified resource-scarce CDs as areas with no gastroenterologists and in the highest tercile of population density, which accounted for 33% (1 of 3) in Prince Edward Island, 32% in Quebec, 25% in Ontario, 7% in British Columbia, and 4% in Manitoba. Only 94 TEs were identified nationwide.

Conclusion:

We found significant variation in liver-specific resources across Canada. Given the increasing number of people living with liver disease, policies must be implemented to address access to specialized care.
Blackout Autotheory
Authors: Cairns James
Published: October 2023

This Offering uses Walter Benjamin’s “Theses on the Philosophy of History” to reflect on the author’s history of blackout drinking. Situating the author’s approach as an experiment in autotheory, the author explains how his sense of selfhood and time lost to addiction shift when thought alongside Benjamin’s idea that history reopens in times of revolution. The author’s unconventional reading of Benjamin raises the question of whether time lost to alcoholic blackouts may be redeemed in the moment of quitting. The article contributes to the literature on addiction narratives by integrating personal storytelling and theoretical analysis of identity, ethics, crisis, and time. More broadly, the article makes a methodological contribution to experimental writing in critical cultural studies that strives to embody the dialectic of self and social.
Reflections and Refractions of Black Radicalism
Authors: hampton rosalind , Bedward AJ
Published: October 2023

This article discusses collaborative Black study that entails dialogical engagement with a range of texts and podcasts about Black radicalism and is further informed by participation in anti-capitalist, anti-colonial activism. The authors describe their process of examining Black radical thought during the COVID-19 pandemic and the ways in which Black radicalism has been and is now being imagined across contexts. Following the work of Cedric Robinson, the authors understand the Black radical tradition as a negation of Western civilization from within Western society, placing it in hostile relation to the neoliberal university. They discuss Black radicalism as anti-capitalist, anti-colonial, feminist, communally oriented, and opposed to neo/liberal ideologies. They address a range of Black socialist traditions, including those labeled communist, Black anarchist, abolitionist, and antifascist to attend to an ongoing critical-creative practice of Black resistance and collective life-making capable of adapting to and challenging the changing conditions of late capitalism.

Linguistic Linked Open Data (LLOD) are technologies that provide a powerful instrument for representing and interpreting language phenomena on a web-scale. The main objective of this paper is to demonstrate how LLOD technologies can be applied to represent and annotate a corpus composed of multiword discourse markers, and what the effects of this are. In particular, it is our aim to apply semantic web standards such as RDF and OWL for publishing and integrating data. We present a novel scheme for discourse annotation that combines ISO standards describing discourse relations and dialogue acts – ISO DR-Core (ISO 24617-8) and ISO-Dialogue Acts (ISO 24617-2) in 9 languages (cf. Silvano and Damova 2022; Silvano, et al. 2022). We develop an OWL ontology to formalize that scheme, provide a newly annotated dataset and link its RDF edition with the ontology. Consequently, we describe the conjoint querying of the ontology and the annotations by means of SPARQL, the standard query language for the web of data. The ultimate result is that we are able to perform queries over multiple, interlinked datasets with complex internal structure. This is a first, but essential step, in developing novel, powerful, and groundbreaking means for the corpus-based study of multilingual discourse, communication analysis, or attitudes discovery.
Designing a Desirable House with consideration of Strengthening the Sense of Peace of the Residents
Authors: Sabaroo Maryam , Mehrali Abazar
Published: October 2023

Humans in modern society are faced with different environmental changes; creation of residential spaces is one of these changes in environmental structure of people in society. The sense of place means people's mental perception of the environment and their more or less conscious feelings about their environment, which places one in an internal relationship with the environment so that one’s understanding and feeling are linked and integrated with the semantic context of the environment. This feeling is a factor that transforms a space into a place with special sensory and behavioral characteristics for certain people. This study investigates the sense of peace in residential buildings and its constituent factors. Now the question is, how to increase the sense of peace in people with proper design in residential environments? For this purpose, this study tends to examine the effect of a desirable house on strengthening the sense of peace of the residents by using a quantitative-qualitative method and using documents, observation, and questionnaires to find out how a suitable design induces a sense of peace in people. Based on findings obtained from field studies and data extracted from the questionnaire, it was found that residential complex indicators and residents' sense of peace have a significant effect on the satisfaction of the residents of the residential complex (p < 0.05). Therefore, it can be claimed with 95% confidence that residential complex indicators and residents' sense of peace had a significant effect on the satisfaction of the residents of the studied residential complex in Tehran. The results also show that using more simple lines and fewer broken lines in the design of building form and considering areas and separating them from each other, as well as color, light, perception, and psychology of the environment are factors that cause a sense of satisfaction and a sense of peace in residents.
Russian Sociology in the Context of Society Digitalization: Results of a Corpus Analysis of Scientific Texts
Authors: Smirnov Andrey
Published: October 2023

Using the analysis of a corpus of texts from eight leading Russian sociological journals, the article examines the impact of the digitalization of society on sociology in 2000-2021. Frequency analysis of 13.8 thousand scientific texts tracked the introduction of concepts related to digitalization into scientific circulation. The article reveals the differences between the journals, due to their editorial policy in the selection of articles. Through content analysis of texts, the author studied the experience of using digital social platforms as a source of data and an object of reflection. The text shows that they are being used more and more over time, and since 2019, one in five publications mentions digital platforms. The study confirmed that due to the introduction of new digital technologies, the frequency and complexity of the software tools used by sociologists is increasing. Since 2015, there has been an increase in the number of studies whose authors develop their own algorithms for data collection and analysis. The identified trends are likely to continue in the future, as all the indicators considered show a steady increase over time. In the conclusions of the article, the author formulates the prospects for studying the patterns of development of sociological science using the methods of corpus linguistics.

Authors: Ivanova Elena
Published: October 2023

The problems of self-determination of diplomats' wives within the framework of professional family interaction are at the center of the study. The factors influencing the status of a diplomat's wife in the conditions of a business trip abroad are highlighted: diplomatic immunity prescribed by international and domestic legislation, the diplomatic rank of the spouse, as well as the social roles, functions and tasks assigned to her within the framework of the norms and rules of diplomatic activity. [d1] The restrictions on the professional career of the wives of diplomats, influencing their choice of a particular trajectory of social behavior, are systematized. The study relied on the included unsystematic observation of phenomena in the daily lives of the families of diplomats as a covert participant; high-quality content analysis of documents – materials from Internet sites and Internet forums; secondary analysis of sociological and historical research data. Conclusions are drawn about the relevance of the legal strengthening of the status of the wives of diplomats, which would take into account the current situation and consolidate the possibilities of a stable perspective.
About Some Social Characteristics of Chronic Stress of Shift Workers in the Arctic Conditions
Authors: Akimov Alexander M.
Published: October 2023

The expeditionary-shift method of organizing labor involves an increase in the intensity of labor during the shift, a longer work shift, a decrease in inter-shift rest in the absence of days off and minimal social and domestic security. The article is devoted to the study of the parameters of stress at work and in the family among men aged 25-54, employed in expeditionary-shift work in the Arctic territories of the Tyumen region. A sociological study was conducted on an organized population of men aged 25-54, employed in expeditionary-shift work for more than five years at one of the industrial enterprises of the Tyumen region. The comparison group consisted of an organized population of men in the same age range, working permanently in the city of Tyumen. Determination of stress at work and stress in the family was carried out according to the WHO standard questionnaire MONICA-psychosocial (Multinational Monitoring of Trends and Determinants of Cardiovascular Disease - Optional Psychosocial Sybstudy). Among the men employed in the expeditionary-shift form of work, most often over the previous period of twelve months, a change in specialty was established, an increase in the load and responsibility at the workplace, a more negative attitude towards work, an increase in conflicts with subordinates, but also the possibility of rest after working day while reducing "other" changes at work. According to the parameters of stress in the family, among men employed in expeditionary-shift work, over the previous period of twelve months, a change in marital status, an increase in conflicts in the family, but also opportunities for a relaxing home rest were most often determined. Thus, the obtained results of a sociological study, which determined a significantly higher prevalence of some factors of chronic social stress after five years of work in the Arctic territories of the Tyumen region, should become a scientific basis for the formation of a socially oriented preventive program to reduce the risks of developing CVD among workers in the oil and gas production complex employed in expeditionary - shift form of work.
Digitalization and Critical Theory of Society
Authors: Ivanov Dmitry
Published: October 2023

The article is presenting а critical analysis of the digitalization discourse which is reflecting not social innovations but managerial and bureaucratic appropriation of virtualization routine practices. Empirical data collected in the authors’ research show digital technologies usage turning into social routine in the Russian largest cities Moscow and St. Petersburg. For a full revealing contradictions and true direction of digitalization, development of critical theory of society is proposed as continuation of the dialectical line of the Frankfurt School neo-Marxism evolution. The totality of domination structures and social control forms in postindustrial society is analyzed on the basis of algorithmic rationality conception introduced by the authors. Algorithmic rationality has replaced technological rationality of the late industrial age. Post-virtualization tendencies and micromovements in everyday life are considered to be an authenticity revolt against total digitalization / coercive virtualization of social life. That authenticity revolt is interpreted as an emancipation potential and escape from the algorithmic rationality realm.
Epistemic Justice for the Dead (transl. by N.V. Romanovsky)
Authors: Turner Stephen P.
Published: October 2023

The classics of social theory have a peculiar status: our current list is the product of past academic strategizing, and the list of favored classics has changed. Currently there is a process of replacing them with older writers who better fit current concerns, and to cancel those who hold the wrong views, or are of the oppressor class, in order to provide epistemic justice for those who don’t deserve their status and uplift those who were wrongly neglected. From an instrumental, careerist point of view, adapting to these changes makes sense. From the point of view of judgement, which differs from the capacity to produce, it does not. Exclusions narrow our range of reference and our capacity to assess in the present. We owe ourselves, and them, not only temporary, fashion driven justice but a larger capacity of judgement detached from the instrumentalization of scholarship.
Applied Sociology of Professor G.P. Davidyuk and Revival of Sociological Science in the Belarusian Soviet Socialist Republic
Authors: Danilov Alexander
Published: October 2023

The article examines the history of academic school of applied sociology of Professor G.P. Davidyuk (1923-2020), assesses his contribution to the revival of sociological science and the institutionalization of sociological education in Belarus. G.P. Davidyuk formed the first scientific structures of a sociological profile in Belarus (sector of social research, Department of sociological research of the Institute of Philosophy and Law of the Academy of Sciences of the BSSR; sector of applied sociology at the Department of Philosophy of Belarusian State University in Minsk, etc.), he wrote the first textbooks "Fundamentals of Applied Sociology" (1975) and "Applied Sociology" (1979). Under his editorship, the country's first "Dictionary of Applied Sociology" (1984) was prepared, the foundations were laid for professional sociologists training at the Belarusian State University (BSU), personnel of the highest scholarly qualification. In the 1970s and 1980s, the Problematic Research Laboratory of Sociological Research of BSU, headed by G.P. Davidyuk, turned into the country's leading scientific center. The work of the Applied sociology sector at the BSU gave an impetus to the development of industrial sociology.
On the crisis of Russian criminal law (re-reading A.E. Zhalinsky)
Authors: Lopashenko Natalia A.
Published: October 2023

The author discusses two types of crisis in Criminal Law: on the one hand, the crisis of criminal law doctrine, which has already been sufficiently investigated, on the other - the crisis of Criminal Law itself, which Professor A.E. Zhalinsky was one of the first to write about, highlighting its (crisis) social and legal signs. Through the analysis of both, using a large illustrative material (economic, statistical, doctrinal), the author comes to the conclusion that Criminal Law is currently in a state of crisis, while different crisis signs have different degrees of severity.
V.S. Nersesyants as a philosopher of law: from Soviet to Post-Soviet
Authors: Savenkov Alexander N.
Published: October 2023

The article analyzes the philosophical and legal ideas and ideas of the famous scientist, thinker, jurist of the last quarter of the XX - beginning of the XXI century, Academician of the Russian Academy of Sciences V.S. Nersesyants. The ideas of ancient philosophers and representatives of the German transcendental-idealistic philosophy had a great influence on the formation and evolution of his legal views, the concept of jurisprudence formulated by him. In this regard, the comparison of his legal views with the ideas of Hegel’s Philosophy of Law, taking into account both dissertations of V.S. Nersesyants, is quite traditional for connoisseurs of the concept of jurisprudence of our contemporary. However, as the experience of a more detailed and in-depth analysis shows, interesting points of similarity of his legal ideas and the nature of their justification are also connected with other representatives of the German intellectual and philosophical culture of discussing the main problems of law and jurisprudence. Understanding the nature of successive and new aspects in the system of legal views of V.S. Nersesyants can serve as a basis for the development of his legal views in modern topical and prospective studies. The article offers some significant clarifications of the content and nature of the philosophical and legal heritage of V.S. Nersesyants, traces the connections of his concept of jurisprudence with the ideas of not only Hegelian philosophy, but also the teachings of other legal philosophers, as well as the later ideas of the neo-Kantian lawyer R. Stammler, the interpretation of law in the “Pure Doctrine of Law” of the Kantian G. Memel, and not only G. Kelsen, which allows us to present the theory of law of V.S. Nersesyants as an original version of this doctrine. The study also demonstrates that the concept of justice in the Philosophy of Law of V.S. Nersesyants has remained one of the unexplained, and promising studies of the foundations of social theory in the doctrine of civilization are also indicated.
Theoretical and legal approaches to determining the methods and procedural forms of protection of traditional values in the Russian state
Authors: Mikhailova Ekaterina V.
Published: October 2023

The article deals with the problem of determining the nature and types of traditional moral and spiritual values as objects of legal protection. Today, Russian legislation does not contain a specific definition of this concept. It is proposed to proceed from the understanding of traditional values as public, state interests, directly or indirectly regulated by the norms of substantive and procedural law. Based on this, only the state (judicial) method of protection is applicable to them within the framework of constitutionally fixed procedural forms.

Published: October 2023

Typically, performance evaluations of High Speed Craft (HSC) are done via towing tanks, however, these facilities come with a high cost, making them inaccessible to many researchers. An alternative testing technique is the free-running test. It provides significant flexibility by not imposing strict equipment requirements and can be carried out in any body of water, offering a more cost-efficient and practical approach to assessing the overall performance of an HSC. This paper presents the development of a free-running scaled model which involved constructing the hull, incorporating data acquisition systems (DAQ), and designing, integrating, and testing the propulsion and steering systems. In addition, this paper presents methods for monitoring the surrounding sea state using a stereo-vision system and commercial wave buoys.

Published: October 2023

The large and mega yachts market shows the increasing trend of “expedition capable” vessels cruising all around the globe, from Antarctica to the Arctic Circle, with the highest comfort standards. Within this frame, the accurate assessment of the seakeeping characteristics is essential for the successful design and eventually the adoption of a stabilization systems. In 2022, the International Standardization Organization (ISO) published the first edition of a set standards to quantify the overall level of comfort on large yachts. The procedure requires the calculation of the Effective Gravity Angle (EGA) and of the Motion Sickness Incidence (MSI) at five locations on the ship, in prescribed environmental conditions and in two different situations: yacht at anchor and in transit. The level of comfort is quantified by a number of stars that goes from one to five, the highest number of stars corresponding to the highest comfort. In the present paper, the application of the ISO guidelines on a large yacht is shown. The Response Amplitude Operators (RAO) are obtained by Hydrostar® software, MSI and EGA are calculated in Matlab®. The comfort level is quantified and shown as weighted value for all periods at different positions and at two speeds and the maximum wave height for the excellent seakeeping is identified.
Procedural Sedation in Dentistry Using Alpha-2 Agonists: Clinical Cases
Authors: Al-tememmi Haider S. , Al-Nayef Ahmed Dahham , Ahmad Rabab Nabeel , Al-Hussaniy Hany Akeel , Al-Tameemi Zahraa Salam
Published: October 2023

BACKGROUND: The presence of acute pain is a serious condition, perhaps, the most terrible negative feeling of a person. Therefore, it is advisable to intraoperatively use means of acute pain control for comfort and to prevent the formation of chronic pain syndrome. Using a multimodal approach to acute pain management allows for better outcomes. The more we engage antinociceptive receptors to control pain, the more comfortable our patient feels. Alpha-2-adrenergic agonists clonidine became an important part of the anesthesiologist's set in the perioperative period. It is the selective effect of dexmedetomidine on alpha-2a central and peripheral receptors and alpha-2c receptors that made it possible to use the drug more widely during procedural sedation.

The joint use of several drugs for procedural sedation is aimed at obtaining the maximum possible comfort for the patient, the attending physician, and the anesthesiology team, reducing the medication load and awakening as soon as possible. Gaining practical experience in using certain combinations of drugs and analyzing useful negative effects helps to balance and satisfy all needs.

PERSONAL EXPERIENCE. Two clinical cases with a typical development but differing in surgical load are presented, describing the effects associated with the use of Precedex (dexmedetomidine hydrochloride) in the introduction of procedural sedation in ambulatory dentistry.

CONCLUSIONS. The use of clonidine or dexmedetomidine (Precedex) intraoperatively together with propofol during procedural sedation in ambulatory dentistry allows reliable control of pain in the perioperative period when basic traditional drugs (acetaminophen, NSAIDs) are used in safe doses, reduces the maintenance dose of propofol during the procedure, prevents the vomiting reflex, provides the possibility of comfortable execution of the doctor's commands (surgeon, implantologist, orthopedics) and faster transfer of the patient to the recovery room.
On the Origin of Aging by Means of Natural Selection
Authors: Walker Richard
Published: October 2023

Formulating a novel concept about the origin of human aging has been constrained by the dominance of a _“classic theory” _that was proposed nearly 70 years ago. Despite concern over the validity of some of its assumptions, the theory remained basic to our understanding of aging’s relationship with natural selection (NS). However, the logic upon which it rests was tested and subsequently challenged. The present theory describes the single cause of human aging consistent with Darwin’s evolutionary requirement for selection of adaptive traits. It describes an emergent property of the developmental program (DP), that is expressed upon completion of ontogenesis. It involves redundant expression of regulatory processes from the last stage of the DP. That mechanism subsequently preserves a non-aging, stable interval of unchanging NS during which reproductive fitness is achieved. Thereafter, loss of DP regulatory redundancy due to reliability limits, stochastic mutation accumulation, reproductive and a specific type of DNA damage, initiates aging which causes an inexorable decline in strength of NS to begin. It starts approximately a decade later than proposed in the classic theory. Since reproduction and aging are inextricably linked by the same emergent property, selection of that regulatory mechanism makes both traits products of NS.
Guilty by association : a phenomenological exploration of Black professionals' experiences with assumptions of criminality at work
Authors:   , Ferguson Marcus Walter, Jr.
Published: October 2023

The stigma of Black criminality has persisted throughout time and been weaponized to the detriment of Black people. Previous on Black criminality have delineated it roots and discussed its outcomes. However, little is known about the shared lived experiences Black people have with Black criminality stigma. In this paper, I argue that Black professionals experiences assumptions of Black criminality within the workplace. I argue that due to the discursive nature of organizations that Black professionals are faced with D(d)iscouses and stigma of Black criminality. Additionally, I argue that Black professionals are forced to manage Black criminality stigma in the workplace. I employed the use of hermeneutic phenomenology to explore the phenomenon of Black professionals experiences with assumption of Black criminality. This dissertation study uses 20 semi-structured interviews with Black professionals to uncover the essence of this phenomenon. A thematic analysis uncovered three emergent themes that constitute the phenomenon: gangster in a suit, guilty till proven innocent, and rooted in criminality. I used stigma management communication, cultural contracts theory, and Big D /little d discourse as guiding research theories. Practical implications, theory contributions, findings, and relevant literature are shared within the study writeup.
An investigation of Algebra resources on TeachersPayTeachers.com : examining features and use of curriculum supplements
Authors:   , Vahle Courtney Paige
Published: October 2023

Teachers choose to supplement their curriculum for various reasons (Drake, 2010) and use online resources to search for and choose these supplements for their curriculum (Silver, 2022). TeachersPayTeachers.com (TPT) is a popular choice for online curriculum resources. TPT is a virtual resource pool that allows teachers to create and share resources so that other teachers can download those resources (for free or at a cost). In this investigation, I used the Teacher Curriculum Supplementation Framework (Silver, 2022) to investigate the features and use of Algebra resources from TPT. A qualitative content analysis of 40 of the top Algebra resources from TPT concluded that teachers primarily use TPT to search for supplemental activities in their classroom for extra practice and are focused on resources that will engage their students. Teachers found the resources to be aligned to standards and of high quality, in contrast to the assessment of researchers (Polikoff & Dean, 2019). Those responsible for creating and choosing curricula for use in classrooms should take note of the importance of engagement for teachers and how to incorporate more engaging activities into the official curriculum materials. Further research should investigate what specific features teachers associate with quality when searching for supplements.
Emotion regulation mediates associations between parenting practices and ethnic minority college students' prosocial behaviors
Authors:   , Dicus Jon Logan
Published: October 2023

The current study examined associations between Black and Latinx college students' mothers' and fathers' parenting practices, students' emotion regulation, and students' prosocial behaviors. College students (N = 567 participants; 64 percent Latinx; 83 percent female) responded to a survey with measures regarding parental nurturance and psychological control, emotion reappraisal and expressive suppression, and types of prosocial behavior. Parenting practices were linked to young adults' prosocial behavior via emotion regulation. Associations between these variables differed for mothers and fathers. In terms of indirect effects, maternal nurturance was indirectly associated with young adults' prosocial behaviors via emotion reappraisal. None of the processes examined were moderated by young adults' ethnicity or gender. Discussion focuses on how the findings support theory and extend research on studying the role of parenting practices, emotion regulation, and prosocial behavior within ethnic minority young adults.
Reevaluation of the Shepherd Mountain and Pilot Knob deposits in Southeast Missouri and their genetic connection
Authors:   , Hunt William
Published: October 2023

Iron-Oxide-Apatite (IOA) deposits occur worldwide and are important contributors of Fe, V, Co, P, rare earth elements (REEs) and other critical elements. Southeast Missouri contains numerous iron deposits that have historically been important producers of iron ore but remain understudied. The Mesoproterozoic Shepherd Mountain and Pilot Knob deposits, hosted within the Taum Sauk Caldera, are some of the oldest deposits mined in the region. The Shepherd Mountain deposit hosts steeply dipping veins of iron ore striking ~E-W. The Pilot Knob deposits consist of the Pilot Knob Hematite (PKH) deposit, characterized by hematite-rich ore beds at the surface, and the Pilot Knob Magnetite deposit (PKM), which is characterized by an intrusion of iron ore in the subsurface. Recent studies have suggested a genetic connection between the deposits via shared fluid pathways. The goal of this study was to provide a geological and geochemical framework for the Shepherd Mountain and Pilot Knob deposits to understand their formation mechanisms and test the proposed genetic connection by using field observations, stratigraphic correlations using rock cores and surface outcrops, alteration mineralogy, and fluid/melt inclusions. Observations show that the Shepherd Mountain and Pilot Knob deposits share similar alteration mineralogy and primary volcanic features, which along with microthermometric data indicating high temperature processes, suggest that these deposits are a result of magmatic/hydrothermal processes like those observed at IOA deposits worldwide such as El Laco (Chile). This study is the first to describe IOA mineralization under Shepherd Mountain linking the Shepherd Mountain and Pilot Knob deposits and demonstrates a need to review and reevaluate other iron deposits within southeast Missouri.
A behavioral genetic examination of the relation between adolescent polysubstance use and educational attainment
Authors:   , Davis Christal Noel
Published: October 2023

[EMBARGOED UNTIL 8/1/2024] Most individuals who use substances use more than one, which is referred to as polysubstance use. Polysubstance use has consistently been related to poorer outcomes compared to use of a single substance, including in regard to educational attainment. However, whether this association reflects a causal relationship or a shared liability giving rise to both adolescent substance use and early school dropout was unclear. In this dissertation project, I conducted a series of behavioral and molecular genetic studies to explore the nature of the relationship between adolescent polysubstance use and educational attainment. Analyses also focused on parsing substance-specific from general substance use effects on educational attainment and on identifying potential gene-environment interactions/correlations between adolescent substance use and educational attainment. Across the three studies, a couple of potentially causal substance-specific effects on high school noncompletion were identified (i.e., for sedative and inhalant/solvent use), but most of the association between adolescent substance use and educational attainment appeared to operate through general substance use effects that were non-causal in nature. The effects of genetic propensity for educational attainment and adolescent substance use operated largely independently to influence actual educational outcomes. The one exception to this was alcohol use, where genetic propensity for educational attainment predicted a greater likelihood of adolescent alcohol use. Results have several implications, including (1) highlighting the need to account for co-occurring substance use in studies of specific substance use effects, (2) supporting the idea that most negative outcomes associated with substance use operate through general rather than substance-specific mechanisms, (3) informing potential targets for prevention and intervention efforts to improve educational outcomes, and (4) supporting the adoption of transdiagnostic approaches to improve our understanding of the etiology of substance use and other externalizing behaviors.
"Reclaimin' my crown" : a Black feminist critical autoethnography of a Black woman educator who left K-12 education
Authors:   , Fatoma Brittany Elise
Published: October 2023

[EMBARGOED UNTIL 8/1/2024] A disproportionate number of Black women educators leave the classroom and do not return. This Black feminist critical autoethnography yielded a personalized narration with a more detailed description of why Black women are leaving the classroom. Furthermore, this study allows me and readers of this work to engage in the implications of being a Black woman educator and the white supremacy culture of K-12 education. The data collected was a detailed retelling of my story, field notes based on photos taken during my teaching experience. Applying Collins' (2000) Black Feminist Thought as an analytic tool provided a solid foundation to discuss oppression and activism in the context of K-12 education while analyzing my experiences critically. There were three major recurring themes I uncovered (1) Oppression based on Intersectional Identities, (2) Reoccurring and Persistent Effects of Trauma, (3) Liberation, Freedom, and Decolonizing the Black Woman's Mind, highlighting some personal accounts that literature aligns with the experience of Black women educators. Specifically, how poor working environment, burnout, white supremacy, white supremacist thinking and action, and hostile racial climates negatively impact the attrition of Black women educators. These findings indicate recommendations for educational leaders and policymakers wanting to retain Black women educators. Some best practices for supporting Black women educators are autonomy to create and build their own support system, do no harm, address implicit biases consistently and continually, and create spaces and environments for Black women without white oversight.
A phase-field formulation for fracture modeling of quasi-brittle and rate- and temperature-dependent materials
Authors:   , Muneton Lopez Rogelio Andres
Published: October 2023

[EMBARGOED UNTIL 8/1/2024] This thesis focuses on the development and application of the phase-field method for fracture modeling of brittle, quasi-brittle, and viscoelastic materials. The study begins with a comprehensive review of the existing theories and approaches proposed by numerous researchers in the field through the years. Subsequently, this study presents the anisotropic phase-field formulation for brittle fracture introduced by Miehe et al. [7, 8], highlighting important concepts and introducing the monolithic and staggered approaches. Building upon this foundation, a new phase-field formulation for quasi-brittle fracture -the regularized PPR model, is introduced, using the Park-Paulino-Roesler (PPR) cohesive fracture model [9]. This new formulation employs a hybrid approach to solve for the displacement problem and the phase-field problem. The regularized PPR model allows for modeling complex crack topologies and capturing size and boundary effects accurately. To extend the model's applicability to viscoelastic materials, a thermo-viscoelastic phase-field formulation is introduced, addressing the rate- and temperature-dependent behavior of such materials. The formulations presented in the different chapters are validated through numerical examples, demonstrating their effectiveness in capturing different fracture phenomena and material responses. Overall, this thesis makes several contributions to the field of fracture mechanics presenting two new phase-field models for fracture modeling of quasi-brittle and viscoelastic materials. This research contributes to advancing the understanding and prediction of fracture in a wide range of materials.

Daun mahoni berpotensi sebagai biopestisida (pestisida nabati) karena mengandung senyawa aktif seperti saponin, alkaloid, tanin, dan flavonoid yang berpotensi sebagai pengendali organisme pengganggu tanaman (OPT) salah satunya hama Spodoptera litura F.. Penelitian biopestida dari daun mahoni dengan proses ekstraksi sederhana perlu dilakukan untuk mengetahui keefektifannya dalam mengendalikan hama ulat grayak dan pengaruhnya terhadap tanaman tomat.

Penelitian yang telah dilaksanakan sejak bulan September sampai dengan Desember 2022. Penelitian dilaksanakan di dukuh Jloko Tengah, desa Plosorejo, Kecamatan Matesih, Kabupaten Karanganyar menggunakan metode rancangan acak kelompok lengkap (RAKL). Terdapat 4 perlakuan penyemprotan yaitu biopestisida daun mahoni dengan konsentrasi 0%, 10%, 15%, dan 20% setiap perlakuan diulang 6 kali.

Hasil penelitian menunjukkan bahwa biopestisida ekstrak daun mahoni dengan konsentrasi 10%, 15% dan 20% dapat menekan serangan hama ulat grayak dan juga berpengaruh pada parameter hasil pada tanaman tomat. Persentase dan intesitas serangan tertinggi terjadi pada kontrol (P0)dengan persentase sebesar 27,53% dan intensitas sebesar 25,46% sedangkan persentase serangan terendah pada konsentrasi 20% (P3) dengan persentase sebesar 4,09% dan intensitas sebesar 2,05%. Hasil parameter hasil jumlah buah dan berat buah pada tanaman tomat tertinggi pada perlakuan konsentrasi 20% (P3) dengan jumlah buah sebesar 29,77 buah dan berat buah sebesar 1642,27 gram sedangkan yang terendah pada perlakuan kontrol (P0) dengan jumlah buah sebesar 21,20 buah dan berat buah sebesar 1209,10 gram pada tanaman tomat.

This study focuses on covered karst terrain situated in Phu Pha Man District, Khon Kaen Province, Northeast Thailand, where records of collapse sinkholes are limited. Here, we investigate the subsurface characteristics and potential causes of sinkhole formation within this area using geophysical methods, hydrogeological techniques, and precipitation analysis. We collected field data by measuring groundwater levels, and conducting electrical resistivity tomography (ERT) surveys. We identified eight cover-collapse sinkholes of various shapes and sizes. Analysis of the groundwater flow indicated that the predominant flow direction runs from north to southeast. Examination of rainfall data showed a progressive increase in total rainfall on a yearly basis, with a significant precipitation event preceding the initial occurrence of sinkholes. The ERT results revealed the presence of highly resistive bedrock, water-saturated layers, and potential cavities. Notably, the tomograms indicated variations in resistivity values, suggesting the presence of irregular surfaces of limestone bedrock and weathered zones as characteristics of karst settings. Intense precipitation is a possible dominant trigger for the formation of the sinkholes. This study contributes to understanding sinkhole formation in karst environments and provides key information for hazard mitigation, not only in the Phu Pha Man District but also in areas with similar geological settings.

This study aimed to develop, implement, and evaluate an RME-supported instructional design for primary school students with MLD risk who had difficulty in multiplication at the third-grade level. In this study, a design-based research method was utilized since it was aimed to apply and assess the RME-supported instructional design to primary school students with MLD risk. The study selected the participants from primary school students with mathematics learning difficulties who had difficulty in number concepts and operations with natural numbers at the third-grade level. Participant students were determined using the criterion sampling method. As data collection tools, the Numbers and Operations Mathematics Achievement Test (NOMAT), Learning Disabilities Symptom Screening Test, curriculum-based assessment, interview, and researcher diary were used. The content analysis method was used to analyze the data obtained from qualitative data collection tools. Descriptive statistics methods were used to analyze the data obtained from quantitative data collection tools. The data obtained from the research are presented under three themes: findings on analysis, design, and development, findings on implementation, and findings on evaluation. The research results show that teaching with RME-supported instructional design is effective in students' multiplication instruction and contributes to their permanent learning.

Servant leadership atau kepemimpinan yang melayani, sebagai suatu pendekatan kepemimpinan berfokus pada pelayanan kepada anggota tim, diyakini sesuai untuk diimplementasikan dalam organisasi pemerintah. Penelitian ini bertujuan untuk: 1) menyelidiki karakteristik servant leadership pada beberapa organisasi perangkat daerah (OPD) berindeks profesionalitas (IP) aparatur sipil negara (ASN) relatif rendah di Provinsi Kepulauan Bangka Belitung; dan 2) mengkaji model kepemimpinan yang melayani sebagai upaya untuk meningkatkan motivasi kerja dan profesionalitas pegawai pemerintah daerah. Menggunakan teori servant leadership dari Greenleaf (1977), dalam versi yang sudah dikembangkan oleh Spears (2010), penelitian dilakukan menggunakan pendekatan kuantitatif deskriptif dalam bentuk survei kepada 10 OPD. Hasil penelitian menunjukkan bahwa karakteristik servant leadership sangat beragam pada kesepuluh OPD. Komitmen pertumbuhan merupakan karakter dengan nilai terendah pada organisasi dengan IP ASN paling rendah dari kesepuluh OPD yang diteliti, sedangkan karakter tersebut justru mendapat nilai tinggi bahkan paripurna pada beberapa organisasi lain. Secara keseluruhan, karakter mendengarkan, empati dan kejelian menjadi karakter kepemimpinan melayani yang menonjol, sementara karakter penyembuhan, persuasi, kepedulian, dan membangun komunitas tergolong paling lemah.

Pertumbuhan penduduk membutuhkan ruang untuk menampung manusia kegiatan. Pembangunan tersebut bertujuan untuk menyediakan ruang bagi manusia, akan tetapi mengakibatkan berkurangnya ruang terbuka hijau. Penelitian ini bertujuan untuk mengetahui pengelolaan dan faktor-faktor pengelolaan ruang terbuka hijau publik, penelitian ini menggunakan metode kualitatif deskriptif menggunakan wawancara dan observasi serta didukung laporan, aturan, dan juga hasil penelitian sebelumnya. Hasil penelitian ini menyebutkan bahwa pengelolaan ruang terbuka hijau, dan peraturan sudah ada di Kalimantan Timur tetapi tingkat pemenuhan ruang terbuka hijau publik baru sebesar 10,76%, kekurangan ruang terbuka hijau publik dengan target 20% karena adanya masalah substansi dan teknis. Berdasarkan hal tersebut, peneliti menyarankan kepada pemerintah agar menyusun perencanaan dan komitmen pimpinan yang kuat untuk mewujudkan kekurangan tersebut.
