The ‘Research in Progress’ article category
Authors: Heinrich Eva , Hill Geof , Kelder Jo-Anne , Picard Michelle
Published: March 2023

ASRHE has introduced a novel article category named ‘Research in Progress’. While the journal’s website provides a succinct definition of this category, initial submissions indicate that further guidance is required to highlight requirements and opportunities. The editors have decided to approach this challenge by constructing an audio editorial, recorded in a conversational format, allowing for multiple voices and nuances to come across.

Important aspects of Research in Progress lie in facilitating publication of tentative results, sharing of research approaches and discussion of research designs. The editors emphasize the need for a strong research foundation, as in literature grounding or careful research question design, and open and honest discussion of successes and failures. Research in Progress is strongly placed to invite collaborations and authors are reminded to be explicit in specifying how they want to work with others to take research forward. The editorial also addresses the situation of research students and how a Research in Progress article might sit alongside thesis writing.

Research in Progress is a developing article category. The editors invite assistance from the higher education research community in shaping this category.
What we do in the shadows: Cultivating faculty teaching and learning relationships in online tutorials
Authors: Hammond Kay , Erlam Gwen , Cedro Carmel
Published: March 2023

Many academic faculties found themselves unexpectedly thrown into the online teaching context during the COVID-19 pandemic. In our context, online tutorial attendances ranged from 20 to 150 students per session, necessitating the creation of a virtual teaching team. This article offers a perspective on developing collaborative team-teaching from the lived experiences of three academics who suddenly found themselves team-teaching online. We reflected on our experiences of collaborative online teaching over the year and shared our stories with each other. Our analysis drew from elements of Appreciative Inquiry and collaborative autoethnography. Based on the five principles of Appreciative Inquiry, we constructed positive and supportive conceptions of our experiences and opened positive possibilities for course delivery and our ongoing relationships. Important outcomes from this study included the development of our online teaching skills and strategies necessary for effective collaboration in online team-teaching. Our findings will be of interest to educational staff transitioning to online team-teaching.

The new time is a period when organizations and employees are facing radical changes on a daily basis. The Covid pandemic has made the existing situation even more complex, and has posed new challenges to organizations, and their employees. Adapting to the "new normality" requires multispectral changes within the organizational structure, culture, work practices, and lifestyle. It is to be expected that the fear of change is ubiquitous, however, this is one of the situations when the crisis should be seen as a potential chance. The authors made an effort to describe and explain the organizational aspects of change in more detail, all with the aim of promoting current business practices.
Perceived alternative job opportunities and turnover intention as preliminary steps in employee withdrawal
Authors: Živković Ana , Fosić Ivana , Pap-Vorkapić Ana
Published: March 2023

Background: Employee turnover represents permanent withdrawal from the organization, which brings longterm unfavorable consequences, especially when it comes to the voluntary early departure of quality employees. Turnover intention is a preliminary step that can predict the employee's intention to leave and is very often the main precursor to the final decision to leave or stay. In addition to internal organizational influences, a strong influencing factor on such a decision is represented by perceived alternative job opportunities. Purpose: The goal of the paper is, therefore, to examine the employee's perception of the possibilities of alternative employment and their turnover intention to determine that the main factor of the environment strongly shapes thinking in the context of leaving. Study design/methodology/approach: The primary research was conducted on a convenience sample of 423 in 15 medium and large enterprises in Croatia (Slavonia and Baranja region) and in various economic sectors: Agriculture, Industry, Energy, Construction, Services, Trade, Transport, Education, and Tourism and Hospitality. The data were subjected to univariate and bivariate analysis. The influence of sociodemographic variables was also tested to identify possible differences between different groups of employees. Findings/conclusions: The results of the research indicate fairly low rates of turnover intention, with a simultaneous perception of very few or weak possibilities for alternative employment. There are no statistically significant differences between the sociodemographic groups, so all employees, for the most part, do not intend to leave the organization in which they are currently employed, but they also do not think that they could easily be employed elsewhere. Limitations/future research: The biggest limitation is the examination of only these two variables without studying cause-effect relationships, which is also a recommendation for future research. It could be helpful to analyze competitiveness on the labor market, because the situation of the market can also affect the perception of employability, which would determine whether the perceptions are close to the real picture.
Principios constitucionales en torno al impuesto municipal sobre el incremento del valor de los terrenos de naturaleza urbana: la desidia del legislador estatal
Authors: Jiménez-Castellanos Ballesteros Inmaculada
Published: March 2023

La crisis inmobiliaria que experimentó España en torno a los años 2008 a 2013 tuvo su reflejo en el aumento de la litigiosidad frente a los Ayuntamientos a propósito de la plusvalía municipal pues convirtió la inexistencia de incrementos o la generación de decrementos en un efecto generalizado. Muchos de estos asuntos llegaron al Tribunal Constitucional a través de cuestiones de inconstitucionalidad. La jurisprudencia constitucional desde 2017 ha puesto de manifiesto que se someten a tributación situaciones en abierta contradicción con el principio de capacidad económica y que corresponde al legislador llevar a cabo las oportunas modificaciones del régimen legal del impuesto. En su último pronunciamiento, el Tribunal ha venido a aclarar el principio de capacidad económica como medida de la tributación en un sistema de cálculo disociado de la realidad, pero al mismo tiempo ha generado mucha controversia por la limitación de los efectos de la declaración de inconstitucionalidad. En este articulo analizamos a la vista de la jurisprudencia constitucional los principios constitucionales que deben inspirar la creación y la regulación de los tributos, así como la desidia del legislador estatal a la hora de acometer esta regulación.
Derechos fundamentales y gestación por sustitución: vuelve el debate jurídico acerca de su regulación a raíz de la STS 277/2022, de 31 de marzo
Authors: Alemán Merlo Sara
Published: March 2023

A raíz de la reciente STS (Sala de lo Civil) núm. 277/2022, de 31 de marzo, ha vuelto a resurgir con fuerza en el debate público la discusión acerca de la posibilidad de regular la gestación por sustitución en nuestro país. A fin de aportar un nuevo enfoque respecto a la respuesta jurídica que dentro del marco establecido por la Constitución Española debe darse a la problemática jurídica que supone esta práctica, en el presente artículo se trata de comprobar la existencia y el alcance de la afectación de los derechos e intereses de los involucrados en lo que podríamos denominar el «triángulo de la GS» —comitentes, gestante y menor—. De tal manera que, tras el correspondiente ejercicio de ponderación, se puede alcanzar una valoración acerca de la incompatibilidad de una posible regulación de la creciente figura de la gestación por sustitución con el marco constitucional español.

O custo de uma educação para a democracia
Authors: Pinto José Marcelino de Rezende
Published: March 2023

Este artigo parte da convicção de que há uma relação intrínseca entre educação e democracia e mostra, com base em dados oficiais, como, no Brasil, o acesso à educação, em especial, aos níveis mais elevados do ensino com garantia de aprendizagem, é um direito negado a muitos brasileiros. Mais do que isso, ele é negado, particularmente àquelas crianças, jovens e adultos pertencentes às famílias mais pobres, ou que vivem no campo, ou que compõem a população negra, condições que, normalmente se agregam numa mesma pessoa. O texto também problematiza a noção de que basta mais educação, qualquer uma, ou de que basta ampliar a escolaridade média da população para o país dar o sonhado passo rumo a uma democracia substantiva, inclusiva e imune a golpes. Somente uma perspectiva ampla de educação, que vá além da mera preparação para os testes padronizados, da disputa pelo maior IDEB, uma educação de perspectiva freiriana, pode fazer a diferença na formação do povo de um país. Por fim, faz uma discussão do modelo de gestão adequado e da demanda de recursos para uma educação pública de qualidade numa perspectiva democrática.
Um balanço do Fundeb no estado de Mato Grosso do Sul (2009 a 2020)
Authors: Fernandes Maria Dilneia Espíndola , Fernandes Solange Jarcem
Published: March 2023

Este artigo apresenta um balanço da execução do Fundo de Manutenção e Desenvolvimento da Educação Básica e de Valorização dos Profissionais da Educação (Fundeb) no período de 2009 a 2020, no estado de Mato Grosso do Sul, nas redes estadual e municipais de ensino. Trabalhou-se com dados do Instituto Brasileiro de Geografia e Estatística (IBGE), do Sistema de Informações sobre Orçamentos Públicos em Educação (SIOPE), hospedado no sítio do Fundo Nacional de Desenvolvimento da Educação (FNDE), do Instituto de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep), do Laboratório de Políticas Educacionais da Universidade Federal do Paraná, documentos coletados nas esferas estadual e municipal, e documentos produzidos pelo movimento sindical docente e pela imprensa. As dimensões aqui evidenciadas para a análise consideraram as matrículas das redes de ensino, o orçamento público disponível, a remuneração docente e os Conselhos de Acompanhamento e Controle Social. Constatou-se que o Estado acelerou o processo de municipalização, transferindo matrículas para os municípios, e que houve redistribuição de recursos do fundo entre as redes de ensino. Em relação à remuneração docente, o Estado pagou o Piso Salarial Profissional Nacional no início da carreira, mas o Piso não tem a mesma incidência de valorização ao longo da carreira do professor. Muitos municípios não pagaram o Piso, mas garantiram a jornada de trabalho de 1/3 extraclasse. Apesar de os Conselhos de Acompanhamento e Controle Social terem respondido às normativas da União em sua composição, ainda têm sido bastante heterogêneos em cada ente federativo.

Authors: Souza Eduardo de
Published: March 2023

A Escola Caetano de Campos assumiu preponderante papel na renovação do ensino pré-escolar e primário paulistano nos anos iniciais da República. Tendo em vista os objetos pedagógicos introduzidos como fundamentais para a modernidade da época, o objetivo deste artigo é compreender as inovações na organização e composição da cultura material escolar que caracterizou essa instituição. Busca-se refletir sobre as finalidades e sentidos que a provisão material adquiriu na organização desse estabelecimento percebendo o modo como os objetos deram materialidade aos projetos de renovação educacional no Estado de São Paulo. Privilegia-se como procedimentos, além de revisão bibliográfica, a análise de impressos pedagógicos destinados ao professorado paulista, como as revistas “Jardim de Infância” (1896-1897), “Ensino” (1912) e “Eschola Pública” (1893) e os documentos oficiais da  Escola Caetano de Campos encontrados no acervo do APESP – (Arquivo Público do Estado de São Paulo) e  no CRE – (Centro de Referência em Educação Mário Covas), em especial, o Catálogo de Instrumentos para  Ciências Naturais da Maison Emile Deyrolle (1931). Em termos teóricos, utiliza-se como aporte para o exercício analítico dessas fontes, as referências de Agustín Escolano Benito (2010, 2017), Dominique Julia (2001) e da historiografia brasileira especializada no tema da cultura material escolar, Castro (2013); Panizzolo (2011, 2013); Petry (2013) e Souza (2007, 2021). Conclui-se que os artefatos presentes nessa instituição tiveram por objetivo prover, além de modos de produção da vida material escolar, a produção/reprodução de valores para se atingir ideais de modernidade e cientificidade contribuindo para disseminar uma determinada concepção de ensino.

Authors: Liu Yan Quan , Lewis Sarah
Published: March 2023

Libraries are adapting to the changing times by providing mobile services. One hundred fifty-one libraries were chosen based on circulation, with at least one library or library system from each state, to explore the diverse services provided to mobile users across the United States. According to the data, mobile apps, mobile reference services, mobile library catalogs, and mobile printing are among public libraries’ most-frequently offered services, as determined by mobile visits, content analysis, and librarian survey responses. Every library examined had at least one mobile website, mobile catalog, mobile app, or webpage adapted for a mobile device. Following the COVID-19 outbreak, services such as mobile renewal, subscriber database access, mobile reservations, and the ability to interact with a librarian were expanded to allow better communication with customers—all from the comfort and safety of their own homes. Libraries are continually looking for innovative methods to assist their mobile customers as the world changes.
Decision-Making in the Selection, Procurement, and Implementation of Alma/Primo
Authors: Guo Jin Xiu , Xu Gordon
Published: March 2023

This case study examines the decision-making process of library leaders and administrators in the selection, procurement, and implementation of Ex Libris Alma/Primo as their library services platform (LSP). The authors conducted a survey of libraries and library consortia in Canada and the United States who have implemented or plan to implement Alma. The results show that most libraries use both request for information (RFI) and request for proposal (RFP) in their system selection process, but the vendor-offered training is insufficient for effective operation. One-third of the libraries surveyed are considering switching to open-source options for their next automation system. These insights can benefit libraries and library consortia in improving their technological readiness and decision-making processes.

Authors: CARDENAS-RETAMAL Javiera , CAMPOS Valerıa , CARTES-VELÁSQUEZ Ricardo
Published: March 2023

Objetive: Assess the association of burnout with socio-educational variables in a sample of Chilean dental students. Material and methods: A cross-sectional study was carried out on dental students in their 4th/5th years of the University of Concepción, Chile. The sample size was estimated at 170 students. The following variables were considered: sociodemographic (sex, age, with whom the student lives and commune of origin), educational (course, course failure, number of years behind and their cause, number of career options, funding, and secondary school type), and Burnout-MBI-SS (Maslach's Burnout Inventory for students). To evaluate the association between the variables, descriptive statistics for quantitative were made using mean and standard deviation for normal distribution variables, and median and interquartile range for non-normal distribution variables; for categorical variables, frequency, and percentage distribution was calculated. Shapiro-Wilk test was used to assess normality, as non-normal distribution was verified for MBI-SS, Mann-Whitney and Kruskal-Wallis was used to estimate statistical differences amongst categorical variables, and Spearman for correlations (p < 0.05). Results: Most students were in 4th year, female with a mean age of 23. For the majority, dental school was their first option, and were studying with a scholarship. Most of them lived with their nuclear family and 58% had at least failed one course. Statistical significant correlations were only found for Depersonalization with students’ age (rho= 0.2420) and reprobation years (rho= 0.1838). Conclusions: Dental students from the University of Concepción, which are female, attending their fifth year, and students who failed courses, especially clinical ones, exhibit higher levels of burnout.

Objectives:To evaluate the effects of double-acting desensitized varnishes applied to bovine tooth enamel bleached with 40% hydrogen peroxide on enamel calcium and phosphorus content and color stability. Materials and Methods:The coronal part of 10 newly extracted bovine teeth (approximately 10x12mm in size) was divided into 5 regions for mineral exchange measurements. Color change measurements of 50 newly extracted bovine teeth were divided into 5 groups. Group 1 unbleached (negative control group), Group 2 was bleached with 40%HP (positive control group), Groups 3,4 and 5 were treated MI varnish, Clinpro White and Profluoroid varnish after bleaching, respectively. Then, all groups were exposed to the tea solution and enamel color measurements were made using the CIE Lab method with spectrophotometer. Mineral change measurements were determined by EDS and morphological changes were observed using SEM. One-way ANOVA, Tukey HSD tests and Tamhane's tests were used for statistical analysis. Results:The content of calcium and phosphorus in enamel were like No bleachingMI varnishClinpro WhiteProfluoroidBleaching. The most color stability after bleaching was determined in teeth which were applied MI varnish applied group ((P< .05). The color stability of Profluoroid and Clinpro White applied group were similar (P> .05). There was a statistically significant difference between the groups in terms of △L and △b averages (P< .05). Conclusions:MI, Clinpro White and Profluoroid varnish used after bleaching were effective in preventing mineral loss from tooth enamel and reducing the susceptibility of tooth enamel to staining with tea.

The questionnaire was delivered to the participants as a paper-based or online version. The data were evaluated using descriptive statistics and multiple logistical regression analysis (p < 0.05). Results: 350 valid responses were received by the educators over the course of 15 days. By means of our findings, we observed that the educators accommodate themselves to the online education on easy terms. However, fewer educators found online education advantageous over face-to-face education. In addition, during online education, it was mostly given a negative opinion as to students' class attendance, class participation, and learning success can be controlled or not. According to the results of the multiple logistical regression analysis, it was shown that the positive opinions of the educators in terms of their perspectives about online education can be increased with the increase in weekly course hours and the current technological infrastructure situation, and can be decreased with the increase in tenure. Conclusion: Our study shows that the perspectives of the educators with regard to online education were not positive in general. However, the results demonstrate that the perspectives of the educators for online education can change with various factors.

Objectives: Present study aimed to evaluate the roughening ability of different laser systems on the middle and apical third of roots. Materials and Methods: Sixty extracted human single-rooted single canal mandibular premolar teeth were randomly assigned to 3 groups (n=20). Standardized preparation and sterilization procedures were performed. The samples were irradiated with Er:YAG, Nd:YAG, and KTP laser systems. The laser irradiations (1.5 Watt) were applied with a spiral motion, starting 1 mm short of the apex and then moving coronally for 10 sec, interleaved with 15-sec recovery intervals for each irradiation. This process was repeated twelve times. The roots that were standardized in the same length and thicknesses were divided parallel to the longitudinal axis. Then, the middle and apical 1/3 surface roughness values of each root section were measured using a profilometer and SEM analysis was performed. The data obtained were analyzed using the two-way analysis of variance (ANOVA) and Tukey post-hoc tests. Results: According to measurements obtained from middle and apical 1/3 surfaces; Although, the statistically highest roughness value was determined after Nd:YAG laser (P < 0.05), the statistically lowest value was detected following the Er:YAG laser irradiation (P < 0.05). Conclusions: In light of the present study, all laser systems caused significant roughness surface. Therefore, laser systems should be carefully applied in human root canals.

This article examines the causes and impacts of early marriage in the East Java province, Indonesia. This study employed a mixed method approach to conduct the research. This study identifies that the causes of early marriage are not just economic, but also sociocultural. Girls who are married early not only are at risk of health problems but also are restricted in their education and work opportunities. In some cases, early marriage is also closely related to the possibility of intimate partner violence. This study highlight the need for close attention to early marriage in Indonesia, which affects many young women and underage girls.

Wing dimorphism in insects is an evolutionarily adaptive trait to maximize insect fitness under various environments, by which the population could be balanced between dispersing and reproduction. Most studies concern the regulatory mechanisms underlying the stimulation of wing morph in aphids, but relatively little research addresses the molecular basis of wing loss. Here, we found that, while developing normally in winged-destined pea aphids, the wing disc in wingless-destined aphids degenerated 30-hr postbirth and that this degeneration was due to autophagy rather than apoptosis. Activation of autophagy in first instar nymphs reduced the proportion of winged aphids, and suppression of autophagy increased the proportion. REPTOR2, associated with TOR signaling pathway, was identified by RNA-seq as a differentially expressed gene between the two morphs with higher expression in the thorax of wingless-destined aphids. Further genetic analysis indicated that REPTOR2 could be a novel gene derived from a gene duplication event that occurred exclusively in pea aphids on autosome A1 but translocated to the sex chromosome. Knockdown of REPTOR2 reduced autophagy in the wing disc and increased the proportion of winged aphids. In agreement with REPTOR’s canonical negative regulatory role of TOR on autophagy, winged-destined aphids had higher TOR expression in the wing disc. Suppression of TOR activated autophagy of the wing disc and decreased the proportion of winged aphids, and vice versa. Co-suppression of TOR and REPTOR2 showed that dsREPTOR2 could mask the positive effect of dsTOR on autophagy, suggesting that REPTOR2 acted as a key regulator downstream of TOR in the signaling pathway. These results revealed that the TOR signaling pathway suppressed autophagic degradation of the wing disc in pea aphids by negatively regulating the expression of REPTOR2.

Osteosarcoma (OS) is the common primary bone cancer that affects mostly children and young adults. To augment the standard-of-care chemotherapy, we examined the possibility of protein-based therapy using mesenchymal stem cells (MSCs)-derived proteomes and OS-elevated proteins. While a conditioned medium (CM), collected from MSCs, did not present tumor-suppressing ability, the activation of PKA converted MSCs into induced tumor-suppressing cells (iTSCs). In a mouse model, the direct and hydrogel-assisted administration of CM inhibited tumor-induced bone destruction, and its effect was additive with cisplatin. CM was enriched with proteins such as calreticulin, which acted as an extracellular tumor suppressor by interacting with CD47. Notably, the level of CALR transcripts was elevated in OS tissues, together with other tumor-suppressing proteins, including histone H4, and PCOLCE. PCOLCE acted as an extracellular tumor-suppressing protein by interacting with amyloid precursor protein, a prognostic OS marker with poor survival. The results supported the possibility of employing a paradoxical strategy of utilizing OS transcriptomes for the treatment of OS.

Pancreatic ductal adenocarcinoma (PDAC) continues to show no improvement in survival rates. One aspect of PDAC is elevated ATP levels, pointing to the purinergic axis as a potential attractive therapeutic target. Mediated in part by highly druggable extracellular proteins, this axis plays essential roles in fibrosis, inflammation response, and immune function. Analyzing the main members of the PDAC extracellular purinome using publicly available databases discerned which members may impact patient survival. P2RY2 presents as the purinergic gene with the strongest association with hypoxia, the highest cancer cell-specific expression, and the strongest impact on overall survival. Invasion assays using a 3D spheroid model revealed P2Y2 to be critical in facilitating invasion driven by extracellular ATP. Using genetic modification and pharmacological strategies, we demonstrate mechanistically that this ATP-driven invasion requires direct protein-protein interactions between P2Y2 and αV integrins. DNA-PAINT super-resolution fluorescence microscopy reveals that P2Y2 regulates the amount and distribution of integrin αV in the plasma membrane. Moreover, receptor-integrin interactions were required for effective downstream signaling, leading to cancer cell invasion. This work elucidates a novel GPCR-integrin interaction in cancer invasion, highlighting its potential for therapeutic targeting.
