Authors: Kosovac Amel , Muharemović Ermin , Trubint Nikola
Published: September 2024

The new challenging trends such as globalisation, liberalisation and privatisation of the postal sector, the emergence of the internet commerce, as well as the demands for high quality commercial postal services operators, create a new ambience for the ways business is conducted by commercial postal services operators which demands innovative approaches. The growing pressure regarding the costs of commercial postal services operators and the increase in volume for pick-up and delivery leads to changes from fixed into variable costs by means of different outsourcing models. This paper proposes a model of calculating the outsourcing services of the technological phases regarding parcel delivery and pick-up, while it is not focusing on the details of the partnership contract. For cost calculation, the model utilizes calculation factors based on the kilometres covered for different categories of vehicles that may take part in the parcel pick-up and delivery phases.

A importância de modelos para o ensino de Física: em foco o princípio de Arquimedes nos livros didáticos de Ensino Médio
Authors: Landi Júnior Salmon , Mesquita Nyuara Araújo da Silva , Queirós Wellington Pereira de
Published: September 2024

Neste trabalho, buscou-se identificar e discutir os modelos explicativos para a abordagem do princípio de Arquimedes em livros didáticos de Ciências da Natureza aprovados pelo Programa Nacional do Livro e do Material Didático 2021. Além disso, propôs-se um modelo explicativo, que pode ser implementado em aulas de Física, a partir da relação entre experimentação e elementos matemáticos e teóricos. Quanto à análise dos livros didáticos, observou-se que a apresentação do princípio de Arquimedes, na maioria dos casos, mostrou-se desvinculada da fundamentação teórica e sustentada por equações matemáticas que não são devidamente explicadas. Por sua vez, o modelo explicativo proposto aqui busca elucidar aspectos conceituais e matemáticos, contribuindo com uma abordagem mais reflexiva em aulas de Física do Ensino Médio.
Conhecimento sobre evolução biológica: um estudo com graduandos em ciências biológicas da universidade do estado do Rio Grande do Norte-UERN
Authors: Araújo Magnólia Fernandes Florêncio de , Menezes Maria da Conceição Vieira de Almeida , Silva Natanael Charles da , Porpino Kleberson de Oliveira
Published: September 2024

O estudo objetivou identificar, nos graduandos ingressantes no curso de Ciências Biológicas da Universidade Estadual do Rio Grande do Norte, o conhecimento que eles apresentam sobre evolução biológica. A pesquisa qualitativa contou com a participação de 37 estudantes e fez uso de um questionário produzido em três fases: exploratória, revisão e consolidação. Os resultados apontam que os conhecimentos dos alunos sobre seleção natural e adaptação estão embasados nas ideias lamarckistas, e à deriva genética é um assunto pouco compreendido pelos discentes. No que se refere à adaptação, prevaleceram as ideias de que o indivíduo se adapta ao ambiente e que incorpora características adaptativas. Assim, considera-se fundamental que a abordagem da seleção natural, adaptação e deriva genética nos livros didáticos seja isenta de termos que induzam o aluno a reforçar uma ideia equivocada ou errônea sobre esses assuntos, e que os docentes deem preferência a estratégias de ensino e uso de recursos didáticos diversificados que sejam delimitados e elaborados numa concepção de aprendizagem crítica e reflexiva para o aluno.

Tornar-se terapeuta comportamental contextual: Habilidades e dicas para iniciantes
Authors: Leugi Guilherme Bergo
Published: September 2024

Foram feitas descrições introdutórias de elementos conceituais importantes para terapeutas comportamentais contextuais. O objetivo é facilitar a aprendizagem desses elementos fundamentais, a partir de descrições simples em linguagem acessível. Foram tratadas oito habilidades consideradas importantes de serem desenvolvidas por terapeutas comportamentais contextuais iniciantes: 1) Ler o ambiente de terapia, o cliente e a si mesmo, a partir de uma visão funcional que inclui o comportamento verbal; 2) Verificar o ambiente, conhecer o mundo do cliente; 3) Construir e manter uma relação terapêutica proveitosa: primeiro ouvir e acolher com empatia, mas, logo, agir; 4) Estabelecer objetivos terapêuticos a partir de análises funcionais amplas ou molares, e não a partir de “comportamentos-problema”; 5) Avaliar concretização de objetivos terapêuticos: cliente muda o seu mundo, e parte desse mundo é você; 6) Conduzir as sessões privilegiando o caráter experiencial (Perguntar menos “porquês” e mais “comos”); 7) Tornar-se obsoleto; 8) Desenvolver outras habilidades constantemente por meio dos estudos e da “experiência de vida”. A ideia é que essas habilidades são subjacentes ao desenvolvimento de competências técnicas relevantes a quaisquer abordagens psicoterápicas comportamentais contextuais. A organização do trabalho foi pensada de modo que tais habilidades estivessem descritas como ações, permitindo que o contato com as sugestões aqui presentes também fosse em alguma medida experiencial. Este texto é um “pretexto” e se pretende base para desenvolver outras habilidades específicas de cada abordagem. Palavras-chave: psicoterapia comportamental contextual; análise comportamental clínica; treinamento de terapeutas; relação terapêutica; processos em psicoterapia.

The demand for natural sweeteners has been increasing; This trend is influenced by several factors, including concerns and controversies surrounding synthetic sweeteners. This study aims to determine the effect of elicitation with ZnO and MgO phytonanoparticles (PTNPs) on Stevia rebaudiana plants. The synthesis of PTNPs utilized the reduction potential of the natural aqueous extract derived from Moringa oleifera leaves. The characterization of the PTNPs was carried out by spectroscopic methods. Scanning electron microscope images of the ZnO PTNPs showed the presence of agglomerated rod-shaped nanoparticles, while the MgO PTNPs were irregularly shaped and agglomerated. Dynamic light scattering analysis showed an average size of 9-30 nm for ZnO PTNPs and 5-10 nm for MgO PTNPs, while zeta potential (ζ) values validated the stability of the PTNPs. The infrared spectra revealed bands corresponding to stretching vibrations of the bonds of the groups involved in the reduction and stabilization of PTNPs. The highest production of rebaudiosides A, E and M was obtained using 1 mg/L of ZnO PTNP. The elicitation with PTNPs mainly with ZnO from the concentration of 20 mg/L induces the production of molecules with antioxidant capacity, obtaining an increase of 137% of chlorogenic acid, while that of caffeic acid is 185%. These results indicated that the application of ZnO and MgO PTNPs induced a higher content of antioxidant compounds in Stevia rebaudiana.

Organizational routines and sustainability strategizing in the port sector
Authors: Aquino-Hübler Eduardo , Barbosa-Lavarda Rosalia Aldraci , Kopp-Leite Felipe
Published: September 2024

The goal of this research was to comprehend the interrelation between the strategizing process and the constitutive aspects of organizational routines. Employing a qualitative methodology, a case study was conducted at the Port Authority of Valencia. Data collection encompassed interviews, observation, and document analysis. Through the analysis of narratives and pattern matching, a permeable relationship between strategizing and routines was identified, indicating an inseparable amalgamation of their key constituents. The demarcation between the components of strategizing and organizational routines is faint, uncertain, and intertwined within an indivisible process. Conceptualizing organizational routines as a fusion of actors, processes, and strategic content, localized spatially and temporally where reasoning and action intersect contingent upon context, underscores the relevance of approaching strategy as a practice, thereby broadening its scope.

Authors: Kellogg Marni B. , Schierberl Scherr Anna E. , McDonough Mary Rose , Ayotte Brian , Letourneau Rayna
Published: September 2024

Background and Purpose:Nurses frequently care for patients who make decisions against medical advice, a challenge that continues during and after the COVID-19 pandemic. This article explores U.S. nurses’ experiences caring for unvaccinated COVID-19 patients and the resulting impacts using Swanson’s Theory of Caring (STC).Methods:Data were gathered through an online survey collecting nurses’ demographics, mental health screening data, and an open‐ended question asking about a personal experience providing care to an unvaccinated COVID‐19 patient. Researchers analyzed 128 responses using content analysis. STC served as the analytical framework.Results:Nurses’ experiences were summarized into two main themes and four subthemes: (a) anger, frustration, fatigue, and resentment (24.2%) and (b) feeling a professional commitment to a nurse’s duty (60.9%). Within the professional commitment theme, subthemes include the following: (a) patients can make an autonomous decision (15.6%); (b) feeling concerned for the patient (6.3%); (c) wanting to take action, educate, and vaccinate (29.7%); and (d) feeling moral conflict (9.3%). Results aligned with STC’s five caring actions: knowing, doing for, being with, enabling, and maintaining belief.Implications for Practice:Nurses experienced emotional challenges caring for the unvaccinated during the pandemic resulting in psychological sequelae, including compassion fatigue and moral distress, in addition to positive outcomes of resilience and enhanced coping mechanisms. This study underscores the multifaceted nature of nurses’ experiences and the emotional, ethical, and professional challenges they encountered when caring for unvaccinated COVID-19 patients. Nurse leaders should address these issues to enhance nurses’ wellbeing and reduce compassion fatigue and dissatisfaction.

Authors: Lévesque Sylvie , Medvetskaya Anna , Julien Dominic , Clément Marie-Ève , Laforest Julie
Published: September 2024

Using a nationally representative sample of 1,264 biological mothers of children aged between 6 months and 5 years, this study identified the prevalence estimates of intimate partner violence occurring in the perinatal period (IPV-PP) and examined the associations between IPV-PP and various characteristics. Findings show that 10.9% of mothers reported victimization to at least one intimate partner violence episode during the perinatal period. Younger maternal age at childbirth, drug consumption, being a single mother, higher parental stress due to the child’s temperament, and higher stress due to family and extrafamilial obligations were all associated with IPV-PP. Findings emphasized that IPV-PP is indeed an important public health matter in Quebec. Interventions should focus on victimization screening during the perinatal period and on enhancing victims’ security and well-being.

The article is a synthetic presentation of the presence of swing dance in the Second Polish Republic. It presents a brief history of this music and dance genre in the United States and its arrival in Poland, where it rapidly gained popularity and began to appear in cinematography. The author focuses on swing dance scenes in the following films: Zabawka (A Toy, dir. Michał Waszyński, 1933), Prokurator Alicja Horn (Prosecutor Alicja Horn, dir. Marta Flanz, Michał Waszyński, 1933), Dyplomatyczna żona (A dimplomatic Wife, dir. Mieczysław Krawicz, Carl Boese, 1937), Szczęśliwa trzynastka (Lucky Thirteen, dir. Marian Czauski, 1938), Zapomniana melodia (Forgotten Melody, dir. Jan Fethke, Konrad Tom, 1937), and Kłamstwo Krystyny (Krystyna’s Lie, dir. Henryk Szaro, 1939). It analyses the costumes of the actors and actresses performing in the scenes in question in order to demonstrate their features which emphasise the vibrancy and dynamism of the fashionable dances. The author also draws attention to the narrative function of the vocal and dance numbers she describes and to gender issues.
Unregistered Polygamy Validation: Isbat Nikah, Polygamy Permit, and Due Process of Law in Indonesian Religious Courts
Authors: Alfitri Alfitri , Imanullah Rijal , Rahman Aulia
Published: September 2024

This article probes whether methods of validating unregistered polygamy in Indonesian Religious Courts have honored the due process of law. Judges have adopted two different methods in validating unregistered polygamy: first, by ordering concerned parties to apply for the issuance of a retroactive marriage certificate (isbat nikah), and second, by advising them to submit a polygamy permit application. Using the sociolegal approach in examining Ratio Legis and selected cases on unregistered polygamy validation across Indonesia, it finds that the existing methods have impacted protecting women’s and children’s rights and marriage law objectives. Opting for isbat nikah means perpetuating violations of the marriage law provisions and objectives, which restrict polygamy through court proceedings to be orderly administration and protect women’s and children’s rights. Meanwhile, requiring unregistered polygamists to remarry by applying for a polygamy permit could impact wives’ rights who are married without registration and their children’s. The 2018 Supreme Court’s Circular prohibiting the Religious Court from accepting applications for isbat nikah of unregistered polygamy shows its tendency to the formal application of the marriage law provisions. Even so, judges adopt the contentious isbat nikah to legalize unregistered polygamy, mainly when the parties involved accept their polygamy and live peacefully. This bottom-up approach arguably better meets the principles of fairness because all legal rights owed to concerned parties are respected.

Authors: Sidiqa Atia Nurul , Rajasa Pahargyan Arya , Endrowahyudi Hartanto , Zakaria Myrna Nurlatifah
Published: September 2024

Background: Calcium hydroxide (Ca(OH)2) is an effective root canal treatment, with calcium and hydroxyl ions effectively released on day 7. However, prolonged use can diminish dentinal tubule hardness and dissolve the hydroxyapatite crystals within them. Nanoparticle Ca(OH)2 demonstrated superior antimicrobial activity compared to conventional Ca(OH)2 because of its deeper penetration into the dentinal tubules.. Purpose: This study aimed to evaluate the effect of particle size on dentinal tubule hardness. Methods: True experiment with fifteen premolars with one root canal, no caries, and apical closure were divided into three treatment groups: conventional Ca(OH)2 (group 1, n=5), Ca(OH)2 nanoparticles (group 2, n=5), and untreated (control group), n=5. All samples were incubated for 7 days, and hardness was measured using a micro-Vickers hardness tester at 1/3 of the root canal. Kruskal-Wallis test followed by Mann-whitney post hoc analysis was used to compare the mean microvickers hardness values among different groups. The level of significance was set at p<0.05. Results: The results showed that there was significant difference between conventional Ca(OH)2 (73.00 ± 2.71) and Ca(OH)2 nanoparticles (67.40 ± 0.62) p=0.01 and the control group (70.68 ± 1.70; p>0.05) and Ca(OH)2 nanoparticles p=0.03. Conclusions: The use of Ca(OH)2 nanoparticles as an intracanal medicament for 7 days reduced dentin microhardness, whereas conventional Ca(OH)2 did not result in any change in microhardness. Particle size affects the hardness of dentinal tubules.

Published: September 2024

Writing activities among higher education students are one of the primary activities. The declining interest and initiative in writing among students contrasts with the skills needed in the workforce. One way to enhance students' initiative in writing scientific papers is through coaching activities. This study aims to prove the effectiveness of Character Excellence Coaching in increasing Personal Growth Initiative (PGI) among students in writing scientific papers. The design used is one-group pretest and posttest design. The respondents were 7 students from Faculty X who are in their 5th and 7th semesters. The measurement tool used was the Personal Growth Initiative Scale-II. Wilcoxon test analysis showed a decrease in personal growth initiative scores after the intervention with a mean difference of 0.429 and a p-value of 0.850 (>0.05). This means that the Character Excellence Coaching intervention was not significantly effective in increasing the personal growth initiative among students.

Published: September 2024

Traditional gold mining around Lake Lebo has a positive impact on people's income, but it has a negative impact on the waters of Lake Lebo. This is evidenced by a 2016 study conducted on 2016 that reported mercury pollution in the sediments and fish of Lake Lebo. The objective of this study is to determine the mercury content in the sediments of Lake Lebo, West Sumbawa. The sampling employed purposive sampling with four research stations based on their utilization around Lake Lebo. The mercury content in the samples was tested using an AAS (Atomic Absorption Spectrophotometer). The sediments of Lake Lebo Meraran contain 0.70 ppm of mercury (lightly polluted). The Meraran Paddy Field Sediment contains 0.31 ppm of mercury (tolerable). The sediments of Lake Lebo Seloto contain 0.22 ppm of mercury (normal). The mercury content in Lake Lebo Rice Snails is less than 0.0001 (undetectable), making them safe for public consumption. Several factors contribute to the undetected mercury in the samples, namely rainfall, floods, waste storage, and phytoremediation by aquatic plants.

The Arksey and O'Malley framework was used as the study methodology which included searching four databases namely Scopus, WoS, Emerald, and Science Direct. A review of 10 out of 894 published articles identified three categories of consequences related to guilt such as (1) consequences for child care, (2) consequences for work, and (3) consequences for the individual. The results from this review would provide a more comprehensive understanding of the consequences of guilt experienced by working mothers. These insights were valuable for practitioners, experts, and policymakers. Additionally, it could serve as a foundation for further and in-depth publications such as intervention or qualitative studies exploring the individual experiences of working mothers in greater detail.

The suicide rate tends to be high every year. College students who start continuing their education tend to experience psychological disorders, so support from the environment plays an important role in helping someone overcome problems. Perceived support will also reduce college students’ feelings of loneliness. This study aims to determine the relationship between perceived social support and suicidal ideation through loneliness as a mediator among university students. In this quantitative study, a total of 395 respondents aged 18-24 who is engaged in a dating relationship or has a best friend was selected through a purposive sampling technique. Three scales were used: the suicidal ideation scale, the perceived social support scale, and the loneliness scale. By using path analysis, results showed a significant relationship between perceived social support and suicidal ideation through loneliness as a mediator. Mediation through loneliness has a greater effect than the direct effect (-0,4676>-0,225) and loneliness acts as a partial mediation. This study implies that this study can help prevent suicidal ideation through increasing perceived social support with reducing the loneliness in a human especially university students.

Trust is an important factor for determining the quality of a professional doctor-patient relationship, particularly in the field of Obstetrics and Gynecology (Ob-Gyn), where it is essential for enhancing healthcare services for mothers and babies. Among the various factors influencing the level of trust patients have in medical personnel, their socio-demographic identity is considered very important. Therefore, this study aimed to investigate the influence of a doctor's social identity, including gender, religion, and race, on the level of trust reported by patients. A quasi-experimental design with a 2 × 2 × 4 within-subject repeated measure approach was utilized to conduct the research. The sample consisted of 171 Javanese Muslim women, who were selected using accidental sampling. The participants were presented with sequences of vignettes containing manipulated doctors’ profiles based on the three observed aspects of social identity (gender, religion, race), alongside a trust scale specifically designed for assessing trust in doctors. The trust scale comprised four dimensions, namely fidelity (loyalty), competence, honesty, and confidentiality. Data collection was then carried out using the trust scale, and subsequent analysis was performed by employing Bayesian repeated measures ANOVA with JAMOVI 1.6.23.0. The results showed that manipulating the social identity of doctors led to variations in the trust level exhibited by the patients, and this was in support of the proposed alternative hypothesis. Specifically, from the main effect analysis, it was found that gender and religion significantly influenced patients’ trust, while race did not. This implied that patients considered gender and religion as important factors when selecting an Ob-Gyn doctor.

This study investigated the impact of six high-intensity interval training (HIIT) running sessions at 1% or 10% slope on various physiological and performance parameters in 25 men. The partic-ipants underwent assessments of VO2max, time to exhaustion at 1% slope (TLim1%), and time to exhaustion at 10% slope (TLim10%) in the initial three visits. They were then randomly assigned to control (CON), HIIT at 1% slope (GT1%), or HIIT at 10% slope (GT10%) groups. Over three weeks, participants performed six HIIT sessions with equalized workload based on their indi-vidual maximal oxygen uptake (vVO2max). The sessions comprised 50% of TLim, with a 1:1 ratio of exercise to recovery at 50% vVO2max. Results indicated significant improvements in VO2max and peak velocity (VPeak) after HIIT at both slopes. Heart rate (HR) behavior differed between sessions for GT1%, while no significant differences were observed for GT10%. Rating of perceived exertion (RPE) significantly reduced for GT1% after the third session, with a similar trend for GT10%. In summary, six sessions of 1% or 10% slope HIIT effectively enhanced VO2max and VPeak, but there was no improvement in TLim performance, suggesting no adaptive transfer between training groups.

Published: September 2024

The energy supply for isolated systems remains a current challenge in Brazil and worldwide, particularly when known solutions are compared regarding cost, the ability to supply energy on demand, and sustainability. In this context, green hydrogen, which has been considered one of the main paths for the decarbonization of the energy chain, is also seen as a potential solution for energy supply in isolated systems. Based on a literature review of articles addressing the topics of green hydrogen and isolated systems, an analysis is conducted on the application of green hydrogen as an energy supply solution for isolated systems. The review identified and collected data on important parameters for comparing solutions, such as CAPEX, OPEX, energy cost, and the price per kilogram of hydrogen. Using these data, analyses were performed to provide an overview of the application of green hydrogen in isolated systems. One of the objectives of this work is to present a comprehensive analysis of the green hydrogen chain and its application in the context of electricity generation, particularly for isolated systems in Brazil.

Background. Sarcopenia is characterized by progressive loss of muscle mass and function. It is often associated with frailty, a syndrome linked to physical disability and shortened survival in various diseases, including cancer patients. Low serum alanine aminotransferase (ALT) values, representing low muscle mass (sarcopenia), is a routine blood test that was shown to be associated with increased frailty and subsequently shortened survival in several cancers. In the current study, we aimed to test the association between low ALT and shorter survival in renal cell carcinoma (RCC) patients and survivors.
Methods. This was a retrospective analysis of RCC patients and survivors, both in and out-patients. We defined patients with sarcopenia as those presenting with ALT < 17 IU/L.
Results. We identified records of 3,012 patients diagnosed with RCC. The final cohort included 1,830 eligible patients (mean age 65.6 ± 13.3 years, 68% were men) of whom only 179 underwent surgical treatment. Out of the eligible cohort, 811 patients (44.3% ( had ALT < 17 IU/L. The mean ALT value of patients within the low ALT group was 11.79 IU/L while the mean value in the higher ALT level group was 24.44 IU/L (p < 0.001). Patients in the lower ALT group were older (67.9 vs. 63.7 years; p < 0.001) and had lower BMI (26.6 vs. 28; p < 0.001). In addition, patients with low ALT had lower hemoglobin values (12.14 vs. 12.91 g/dL; p < 0.001), higher serum creatinine (1.49 vs. 1.14; p < 0.001) and higher platelets to lymphocytes ratio (178 vs. 156; p < 0.001). In a univariate analysis, low ALT levels were associated with a 72% increase in mortality (95% CI 1.46-2.02, P < 0.001). In a multivariate model controlled for age, male gender, hemoglobin, platelets, LDH, neutrophil to lymphocytes ratio and platelets to lymphocytes ratio, low ALT levels were associated with a 27% increase in mortality (HR = 1.27, 95% CI 1.08 – 1.51; p = 0.005].
Conclusion. Low ALT values, indicative of sarcopenia and frailty, are associated with shortened survival of RCC patients and survivors and could potentially be applied for optimizing individual treatment decisions.

European Union (EU) regulations on in vitro diagnostics (IVD) and on serious cross-border threats to health provide for the establishment of European Reference Laboratories (EURLs) and their harmonisation and cooperation with National Reference Laboratories (NRLs). While the EURLs under the IVD Regulation will be operational by 1 October 2024, the EURLs under the Regulation on serious cross-border threats to health will be operational by January 2025. Although NRLs may have been operating for a long time on the basis of national legislation, they should now cooperate with each other and with EURLs in a network of centres of excellence for the authorisation and post-market surveillance of IVDs and for the epidemiological surveillance and control of communicable diseases. The term "reference laboratory" has long been used colloquially to refer to many kinds of laboratories, regardless of their tasks, competencies, responsibilities and designation. To clarify the roles and functioning of EURLs and NRLs, we evaluated the relevant current EU provisions and compared the findings with those of reference laboratories designated by other organisations, calibration (reference) laboratories and referral laboratories, which are simply referred to as "reference laboratories".
Life Cycle Assessment of Crude Oil-Contaminated Soil Treated by Low-Temperature Thermal Desorption and Its Beneficial Reuse for Soil Amendment
Authors: Song Young Ho , Kim Geon Yong , Kim Da Yeon , Hwang Yong Woo
Published: September 2024

The LTTD process for highly concentrated crude oil-contaminated soil was studied to evaluate the remediation efficiency. In addition, the environmental impact difference between HTTD and LTTD was studied. OpenLCA software obtained from PE International was used to perform the analyses. The total ADP environmental impact of the HTTD process was 1.63E-04 MJ, whereas the total GWP impact was 4.14E+02 kg CO2-eq. In contrast, the LTTD process exhibits total ADP and GWP environmental impacts of 1.29E-04 MJ and 2.78E+02 kg CO2 eq, respectively. Analysis of the overall environmental impact reduction revealed that replacing the HTTD process with the LTTD process resulted in a total ADP reduction of 3.40E-05 MJ (20.5%) and a GWP reduction of 1.36E+02 kg CO2 -eq (32.9%). It is inferred that the LTTD treatment of contaminated soil can significantly reduce the environmental impact compared with conventional incineration and HTTD processes. Additionally, the LTTD-treated soil with coke or carbonized residue could act like biochar as a soil amendment. Approximately 50% of organic hydrocarbon contaminants are sequestered into coke or carbonized residues on the soil surface. With additional analyses of various oil-contaminated soils, the potential utility of LTTD-treated soils is expected to be maximized.
