Impact Evaluations of Teacher Preparation Practices: Challenges and Opportunities for More Rigorous Research
Authors: Mancenido Zid
Published: May 2023

Many teacher education researchers have expressed concerns about the lack of rigorous impact evaluations of teacher preparation practices. I summarize these various concerns as they relate to issues of internal validity, measurement, and external validity. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher preparation practices published in peer-reviewed journals between 2002–2019. Although I find that very few studies address issues of internal validity, measurement, and external validity, I highlight some innovative approaches and present a checklist of considerations to assist future researchers in designing more rigorous impact evaluations.
A Comparative Study of Single-Constraint Routing in Wireless Mesh Networks Using Different Dynamic Programming Algorithms
Authors: Shukr Sabreen Mahmood , Alwan Nuha Abdul Sahib , Ibraheem Ibraheem Kassim
Published: May 2023

Finding the shortest route in wireless mesh networks is an important aspect. Many techniques are used to solve this problem like dynamic programming, evolutionary algorithms, weighted-sum techniques, and others. In this paper, we use dynamic programming techniques to find the shortest path in wireless mesh networks due to their generality, reduction of complexity and facilitation of numerical computation, simplicity in incorporating constraints, and their onformity to the stochastic nature of some problems. The routing problem is a multi-objective optimization problem with some constraints such as path capacity and end-to-end delay. Single-constraint routing problems and solutions using Dijkstra, Bellman-Ford, and Floyd-Warshall algorithms are proposed in this work with a discussion on the difference between them. These algorithms find the shortest route through finding the optimal rate between two nodes in the wireless networks but with bounded end-to-end delay. The Dijkstra-based algorithm is especially favorable in terms of processing time. We also present a comparison between our proposed single-constraint Dijkstra-based routing algorithm and the mesh routing algorithm (MRA) existing in the literature to clarify the merits of the former.

A háború keselyűperspektívából: ökológiai diskurzusok az orosz–ukrán háború árnyékában
Authors: Győri Zsolt
Published: May 2023

Dolgozatom alapötletét három videó adta, melyek az ökológiai nyelvezet és a természetfilmes hangalámondás stílusát imitálva fogalmaznak meg ukránpárti és oroszellenes üzeneteket. A videók verbális kommentárját az „ukránosított Attenborough” hangjaként jellemzem és népszerű filmjeinek releváns vetületeit kiemelve az antropocentrikus biologizálás gyűlöletbeszédtől megkülönböztetendő formájaként elemzem (1. rész). A tanulmány további részében az ökológiai allegóriákat alkalmazó nyelvről és beszédről a képekre, egy konkrét képtípusra helyezem át a hangsúlyt. A felderítő drónok által rögzített, saját terminológiám szerint keselyűperspektívából készült felvételek vizsgálata előtt megvizsgálom e fegyvertípus stratégiai hadviselésben betöltött szerepét, azokat a tulajdonságait, melyek a modern hadszíntér megkerülhetetlen szereplőjévé tették, és amelyek miatt az orosz-ukrán háborúban is széles körben alkalmazzák (2. rész). A keselyűperspektívát egy természeti-technicizált tekintet metaforájaként vizsgálom, párhuzamba állítva a keselyűk fiziológiai és etológiai ismérveit, valamint a drónok (tömeggyártású quadrokopterek) technikai paramétereit és harcászati alkalmazásukat támogató jellemzőit (3. rész). A keselyűperspektíva minél pontosabb definíciójára törekedve amellett érvelek, hogy a tekintet e formája nem kínál belépést egy emberin túli, zoomorf világba, szemben azokkal a természetfilmekkel, melyeket madarakra szerelt kamerával forgattak. Értelmezésemben az állati és technikai tekintetek összekapcsoltságának hiánya miatt a keselyűperspektíva pontosan azt a fajta immerzív élményt nem képes közvetíteni, ami a háborúábrázolás másik népszerű kortárs formájában, a testkamerák affektív és szomatikus felvételeiben gazdagon megjelenik. Az oroszukrán háborúban készült drámai képsor példáján keresztül tovább elemzem a megtestesült tekintet és a keselyűperspektívában megképződő távolságtartó tekintet különbségeit, és az utóbbit akként jellemzem mint ami az érinthetetlenség és az irányítás érzetével ruházza fel a nézőt (4. rész).
Yüzüncü Yılında Lozan Barış Anlaşması’nın Önem, Anlam Ve Hükümlerinin Hatırlanması Ve Hatırlatılması
Authors: Tulun Teoman Ertuğrul
Published: May 2023

Bu yazı, 24 Temmuz 1923'te imzalanan ve 100. yıldönümünü kutladığımız Lozan Barış Antlaşması'nın Türkiye Cumhuriyeti'nin temellerinin atılmasındaki önemini vurgulamaktadır. Türk tarihinde bir dönüm noktası olan bu Antlaşma, Mustafa Kemal liderliğindeki Milliyetçi Hareket'in parçalanmış bir imparatorluktan bağımsız ve egemen bir Türk devleti kurma gücünü gözler önüne sermiştir. Cumhuriyetin temel ilkeleri olan egemenlik ve bağımsızlık kavramları, bu mücadeleden doğmuş olup, Türk Kurtuluş Savaşında önemli yeri bulunmaktadır. Birinci Dünya Savaşı'nı sona erdiren diğer antlaşmaların aksine, Türkiye Cumhuriyeti'nin "doğum belgesi" olarak kabul edilen Lozan Barış Antlaşması, geçerliliğini ve kalıcılığını korumaktadır. Bazı kesimlerin eleştirilerine rağmen, Türk halkı ezici bir çoğunlukla Antlaşmayı desteklemektedir. Son dönemde Antlaşma'nın bazı yönlerinin Türkiye dışındaki akademik platformlarda sorgulanması, bu tarihi belgenin dünyanın dikkatine sunulması için bir fırsattır. Yüzüncü yıl kutlamaları, Türkiye'nin tarihinde bağımsızlık ve egemenliğin önemini vurgulayacak ve Antlaşmayı değiştirmeye yönelik herhangi bir girişim, muhtemelen Türk kamuoyunun güçlü muhalefetiyle karşılaşacaktır.
Feasibility of a Digital Coaching Program for Improving Mental Well-Being and Emotional Intelligence: Pragmatic Retrospective Cohort Study
Authors: Peiper Nicholas C. , Pettitt Adam , Shah Bela , Atwood Oliver , Pfeffer Jeffrey
Published: May 2023

Within the past decade, digital coaching programs (DCPs) have emerged as an evidence-based modality to improve mental well-being and emotional intelligence, although there is limited evidence in real-world context. This pragmatic retrospective cohort study sought to determine the preliminary effectiveness of a DCP in improving mental well-being and emotional intelligence within a real-world context. We hypothesized that there would be a significant increase in mental well-being and emotional intelligence. This study included 588 people that voluntarily enrolled in an eight-week, blended care DCP offered through their employers from October 2021 to August 2024. Participants completed the World Health Organization-Five Well-Being Index (WHO-5) at baseline and then weekly until the end of the program as well as the Brief Emotional Intelligence Scale-10 (BEIS-10) at baseline and the end of the program. In multivariate linear mixed models adjusting for age, gender, program engagement, and program completion, we observed a significant increase in WHO-5 scores (Cohen’s d = 1.98, p<0.001). Over half of the sample (55.4%) experienced a clinically meaningful improvement on the WHO-5 (i.e., at least a 10-point improvement). BEIS-10 scores also significantly increased from baseline to the end of the program after adjusting for relevant correlates (Cohen’s d = 1.32, p<0.001). These results demonstrate that DCPs can be a viable option for individuals looking to improve their mental well-being. Studies employing hybrid effectiveness-implementation trial designs are now needed to further evaluate the real-world effectiveness of this program.

Authors: Hijikata Keiichiro , Oka Motonori , Yamaguchi Kazuhiro , Okada Kensuke
Published: May 2023

This paper introduces variationalDCM, an R package that performs recently-developedvariational Bayesian (VB) estimation methods for diagnostic classification models (DCMs).DCMs are a class of discrete latent variable models that reveal respondents’ current knowledge statuses and perform clustering based on these statuses mainly in educational measurements. This package enables computationally efficient Bayesian estimation for various DCMs in large-scale datasets. The paper describes the parsimonious and generalizedDCMs that variationalDCM supports and provides the empirical illustration of the functions in this package.
Identifying Careless Responding in Web-Based Surveys: Exploiting Sequence Data from Cursor Trajectories and Approximate Areas of Interest
Authors: Pokropek Artur , Żółtak Tomasz , Muszyński Marek
Published: May 2023

The increasing use of web-based surveys in social sciences research has brought forth the challenge of effectively identifying and managing inattentive/careless responding. Existing detection methods have shown limited success, highlighting the need for improved methodologies. This study introduces a novel approach that utilizes time-stamped action sequence data of mouse movements and employs deep learning models to detect careless responding. The concept of Approximate Areas of Interest (AAOIs) is introduced, along with the application of Gated Recurrent Units (GRUs) and Bidirectional Long Short-Term Memory (BiLSTM) models. This research presents a flexible and efficient tool that can be applied across different scales and survey contexts. The results demonstrate the superior performance of the proposed approach in identifying survey careless responding, achieving up to 95% accuracy when tested on experimental data with induced inattentiveness. This approach offers a potential breakthrough in overcoming the pervasive challenge of detecting careless responding in computer-based surveys.
The Impact of Historical Loss on Native American College Students’ mental health: the protective role of ethnic identity
Authors: Fetter Anna , Thompson Mindi
Published: May 2023

Objectives: Culturally relevant stressors and protective factors are vital to understanding and effectively supporting Native American/Alaskan Native (NA/AN) college students’ mental health and well-being. This study examined the theorized pathways among historical loss, well-being, psychological distress, and the proposed cultural buffer of ethnic identity in the Indigenist Stress-Coping Model (ISCM). Methods: Cross-sectional data were collected via online survey and analyzed using structural equation modeling. Sample Description: Participants were a national sample of 242 NA/AN college students. Participants were predominantly women (n = 185; 76%) and Median age was 21. Results: Partial support was found for the ISCM. Participants reported frequent thoughts of historical loss, which were associated with lower well-being and higher levels of psychological distress. Ethnic identity moderated the relationship between historical loss and well-being such that those with stronger ethnic identities reported a weaker relationship between historical loss and lower well-being. Conclusions: Results underscore the importance of culturally specific risk and protective factors in NA/AN college students’ resiliency and inform needed interventions and systemic change in higher education.

Published: May 2023

Finding the optimal debt-equity mix, where shareholders’ wel­fare and firm value are maximized is the goal of every business organiza­tion. The literature review revealed a broad spectrum of mixed and contra­dictory empirical findings on this topic, suggesting that the debate is far from over. This paper aims to assess the impact of capital structure on the profitability of the tourism industry in the European continent. This study is motivated by the importance that the tourism industry has for the economic development of European countries. The sample includes all European-list­ed firms in the tourism industry. Data is extracted from the Thomson Reu­ters (Refinitiv) database for a period of 10 years, i.e., 2010-2019. Panel data regression is used to determine the impact of the debt-to-assets ratio on the return on assets. The results reveal that the debt ratio has a significant neg­ative impact on ROA, but not on ROE.
The Lorax Effect
Authors: Gagnon Alexandra Hélène
Published: May 2023

As the globe continues to experience the effects of climate change, researchers must continue to investigate factors that contribute to individuals' attitudes concerning climate change. This study utilizes survey data from 1,539 Canadians gathered in 2019. The data was analyzed using ordinary least square linear regression to analyze how political ideology, gender, and level of education correlate with individuals’ level of environmental concern. Approximately 83.2% of Canadians rated themselves as having a moderate level of environmental concern or higher in the collected survey data, suggesting that most Canadians express some amount of environmental concern. Canadians with a conservative political ideology have a lower level of environmental concern than their liberal counterparts. Within the Canadian context, there is no statistically significant relationship between level of education and concern for the environment. Females are more concerned, on average, about the environment, compared to males. Canadians’ gender identity seems to influence their level of environmental concern. However, more representation of non-binary individuals is needed in future data-gathering to analyze non-binary individuals' level of environmental concern. The paper further discusses these variables' effects on the level of environmental concern.

Nos dias atuais, com a globalização da economia, há uma incessante corrida tecnológica no mundo inteiro pela automação industrial, visando atingir três pontos básicos: minimização dos tempos de fabricação, minimização dos custos de fabricação e a fabricação com qualidade adequada, aperfeiçoando cada vez mais as máquinas- ferramentas existentes, pois através dessas máquinas é que são construídas outras máquinas e novos produtos, utilizados em diferentes áreas industriais. Na ótica da automação industrial, a máquina-ferramenta CNC (comando numérico computadorizado) é um sistema mecatrônico típico que está sendo continuamente aperfeiçoado e, cujos projetos existentes privilegiam a integração do controle de movimento no chão-de-fábrica em tempo real, o controle discreto de eventos em plataformas standards e PCs, além do aperfeiçoamento da capacidade de operação e controle de máquinas-ferramentas. O setor industrial brasileiro precisa continuar a investir em recursos humanos e em equipamentos na área de automação. No estágio em que se encontram as nossas empresas frente às tendências de uma economia globalizada, só é possível uma competitividade com níveis aceitáveis de qualidade se partirmos para a automação de pelo menos alguns setores da produção. Na área da fabricação por usinagem, as máquinas-ferramentas sofreram uma grande transformação tanto na sua concepção quanto na sua construção. O operador das máquinas convencionais era responsável pela qualidade final do produto. Hoje, temos como ferramentas auxiliares o computador e outros componentes eletrônicos/mecânicos que, quando bem utilizados, permitem a usinagem de peças complexas com maior precisão e em tempo mínimo. Este trabalho trata da problemática envolvida na seleção de parâmetros de usinagem e os melhores setups de produção (otimização dos parâmetros) nas operações de usinagem por torneamento em um ambiente escolar, com a produção de um guia ilustrativo que dará suporte ao docente e facilitará o aprendizado dos alunos nas aulas práticas da disciplina de comando numérico computadorizado - CNC.

Authors: Chumak Yu.V. , Loban G.A. , Faustova M.O. , Ananieva M.M. , Havryliev V.M.
Published: May 2023

According to the literature, microorganisms of the genus Kocuria are becoming widespread, but not as avirulent representatives of the normal microbiota of the human body, but as pathogens.

Recently, after the identification of the causative agents of infectious and inflammatory processes, various types of Kocuria have been included in the list of etiological agents isolated from patients with cholecystitis, endocarditis, peritonitis, and meningitis as well as from carious tooth cavities and post-extraction tooth sockets. Bacteria of the genus Kocuria possess pathogenicity that enables them to play an important role in the occurrence of infectious and inflammatory processes in various organs and systems of the human body. Given that antibiotics are the most commonly used drugs of choice in medical and dental practice for the treatment of infections and inflammations, antibiotic resistance is considered as a global health and development threat.

In order to overcome the challenge of antibiotic resistance, antiseptics, a group of medicines with a pronounced antimicrobial effect, are being increasingly used for the treatment of infectious and inflammatory processes. The purpose of this study is to investigate the antibacterial and antiadhesive activity of dekasan, and drugs of comparison, chlorhexidine and iodoform, against clinical isolates of Kocuria spp. isolated from the oral cavity of patients with infectious inflammatory post-extraction complications. Materials and methods: five clinical isolates of Kocuria spp. were studied as microorganisms isolated from patients, who received the treatment for infectious and inflammatory post-extraction complications at the medical and surgical departments of Poltava Regional Center of Stomatology – Dental Polyclinic. We determined the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBcC) of antiseptics against clinical isolates of Kocuria spp. taking into account ISO recommendations. The adhesive properties of clinical isolates of Kocuria spp. were assessed by exposing them to subbacteriostatic concentrations of antiseptics, namely dekasan, chlorhexidine, and iodoform. The evaluation was conducted using erythrocytes of blood group 1(0) Rh+ and considering the index of microorganism adhesion (IAM) following the method developed by V. I. Brillis. The results obtained have demonstrated variations in the antimicrobial and anti-adhesive activities among the tested antiseptics, dekasan, chlorhexidine, and iodoform.

Perusahaan perlu menerapkan kebijakan yang tepat untuk bisa bersaing di tengah tengah persaingan industri yang saat ini mulai normal pasca pandemi Covid-19 menyerang. Pengendalian dan pengelolaan piutang sangat diperlukan untuk meminimalisir risiko kerugian perusahaan salah satunya kebijakan kredit yang efektif harus diterapkan. Tujuan dari penelitian ini adalah untuk menganalisa perputaran piutang di PT. Sarana Insani dengan membandingkan analisis rasio  Receivable Turn Over (RTO) dan Average Collection Period (ACP). Penelitian ini menggunakan analisis deskriptif. Sumber data yang diperoleh menggunakan teknik wawancara dan data sekunder yaitu data penjualan kredit dan data piutang yang diolah. Berdasarkan hasil pembahasan, kondisi RTO dan ACP pada tahun 2015 sampai dengan 2020 mengalami fluktuasi, RTO maupun ACP setiap tahun nya perusahaan belum mampu melakukan pengumpulan piutang secara maksimal. Diketahui bahwa kebijakan kredit yang diberikan kepada Customer oleh perusahaan adalah setelah selesai satu partai baru bisa ditagihkan, dan ini kurang efektif karena untuk menunggu satu partai selesai piutang baru dapat ditagihkan. Maka akan mengakibatkan ketidakpastian terkumpulnya piutang, dan investasi dalam piutang tidak akan terprediksi dengan baik. Perusahaan perlu meninjau kembali kebijaksanaan tentang piutang yang dapat ditagihkan setelah satu partai selesai dengan penerapan kebijaksanaan atau metode lain, misalnya ditetrapkan nya kebijakan kredit dengan sistem n/30 atau n/60 sehingga pengumpulan piutang dapat dengan pasti diterima.
