Authors:   Department of Power Electronics and Automation of Energy Conversion Systems, AGH University of Science and Technology, Cracow, Poland, Jarosz Anna DorotaJarosz
Published: March 2024

This article focuses on intelligent energy management in microgrid systems, providing a comprehensive control engineering perspective on power electronics-based operation. The proposed approach utilizes advanced control algorithms to optimize power flow, load balancing, and integration of renewable energy sources within the microgrid. This article proposes the integration of multiple control strategies to create a hybrid approach that overcomes their disadvantages and addresses the limitations of individual algorithms. We aim to achieve a more robust and adaptive microgrid control method by combining the strengths of different control techniques. This hybrid approach leverages the power electronics capabilities while mitigating their limitations.
The Main Approaches to the Financial and Institutional Conditions for the Emergence of Scientific and Educational Consortiums
Authors: Harchishina E.
Published: March 2024

Currently, scientific and educational consortia are becoming increasingly popular forms of collective action in the field of science and education. They are turning from static structures into dynamic communities that have a high degree of flexibility and are able to quickly respond to new challenges and trends. Consortia bring together universities, research centers, companies and other organizations in order to jointly perform scientific and educational tasks, exchange information and resources. Using their capabilities, such groups can achieve great results that are not available to one person or one organization. In science and education, various models of cooperation are used, which contribute to the creation of scientific and educational consortia. By a decree of the Russian government dated May 13, 2021, the Priority 2030 Strategic Academic Leadership program was adopted, which is aimed at supporting universities and stimulating their participation in achieving the national development goals of the country. Consortia are an important mechanism for the implementation of this program. The strategic academic Leadership program "Priority 2030" has become an important incentive for the development of consortia in the field of education and increased funding for universities. According to the data of form VPO-2, reviewed in this article, there has been an increase in the volume of cash receipts since 2021. The analysis of the main advantages of Scientific and Educational consortia shows that consortia allow solving complex tasks that are inaccessible to one scientist or educational institution. In addition, consortia ensure efficient use of resources, which is especially important in conditions of limited budgets.

Authors: Zhifang Ma , Xiaoguang Guo
Published: March 2024

To ensure the safety and stability of high-speed rail lines and reduce external interference, it is essential to build a large number of elevated bridges. These elevated bridges account for a considerable proportion of the total length of high-speed rail lines. However, when high-speed rail lines pass through earthquake prone areas, the likelihood of earthquakes occurring when trains pass through bridges increases significantly. Therefore, it is necessary to study the dynamic response of bridge structures under earthquake action to ensure the safety of bridges during train operation and operation. The optimization scheme proposed in this article has undergone moderate impact tests, and the results show that the maximum lateral displacement of the bridge can reach 124 mm, while the maximum vertical acceleration is 5.16 m/s2, Exceeded the safety limit of 0.35 g. Through the analysis of train derailment coefficient, wheel load reduction rate, lateral sway force, lateral and vertical acceleration, and Spelling comfort index, we have come to the conclusion that bridges can ensure the safety of train operation in the absence of earthquakes and small earthquakes, and can also maintain certain stability under medium and large earthquakes. These research results have important guiding significance for the design and construction of high-speed rail lines. By optimizing the bridge structure and adopting relevant technical measures, the seismic disaster resistance of high-speed rail lines can be further improved, ensuring the safety and comfort of passengers during travel. At the same time, these research results also provide useful reference and inspiration for the construction and improvement of future high-speed rail lines.

Authors: Liu Lin , Chen Yan , Yu Jun , Cheng Rui
Published: March 2024

Global trade of wood forest products is a complex system, and its flow between trading countries forms a trade network of wood forest products. The transmission efficiency of the trade network largely depends on its network structure. The commonly used method in recent years to analyze the network structure is complex network analysis. Therefore, this study used the complex network method, through using kernel density curves every 5 years to show distribution changes of complex network indictors to study the evolution of the trade network of global trade of wood forest products, based on trade data from 1995 to 2020. The results show that the trade relationship between countries is deepening. Compared with resource-based wood forest products, the trade of deeply processed wood forest products is larger in scale, more complex in structure, and more closely linked. The core countries in global wood forest products trade mainly comprise North American and European countries, while several developing countries in Asia with abundant forest and labor endowments are gradually joining the core tier and jointly control the trade market. We also revealed the intervention of world forestry development goals and national forestry policies on changes to trade structure and trade groups.
Institutional framework for the Financial Supervision Authority's control over the activities of an insurance agent
Authors: Bidziński Mariusz , Ulijasz Bogusław
Published: March 2024

Objectives

The subject of consideration is the supervisory powers of the Financial Supervision Authority in terms of the control of insurance agents. Act of 15 Dec 2017
on Insurance Distribution introduced the possibility of conducting inspections of insurance agents' activities by supervisory authorities. The Financial Supervisory Authority is the body that supervises the financial market, including the supervision of activities related to the distribution and redistribution of insurance

Material and methods

The article has been drawn up mainly using the formal-dogmatic method. It involves the description and systematization of legal norms, interpretation of regulations, as well as an analysis of the practice of application of the law by both state administrative bodies and courts

Results

KNF inspectors, in the course of their inspection, have the authority to demand from the inspected insurance agent access to the documents of the inspected entity and to the data and information contained in the information and communication systems. However, this entitlement is not absolute. Such a request may only concern the documents and data of the controlled entity, and moreover, it is only updated when it falls within the substantive scope of the inspection

Conclusions

Notwithstanding the above, the agent also remains the disposer of information covered by the secrecy of communication . The contents of the mailboxes of insurance agents, like any correspondence, are protected by the secrecy of communication, regardless of the content (art. 49, para. 1 of the Polish Constitution). In order for the supervisory authority to effectively demand access to information contained in the correspondence of an insurance agent, it should first obtain this access through a separate procedure provided for by the law.

Cel pracy

Celem artykułu jest analiza przyczyn różnic w rozwoju regionalnym Wielkopolski oraz Warmii i Mazur.

Materiał i metody

W badaniu sięgnięto do metodologii stosowanej w nauce o polityce i administracji, zastosowano metodę porównawczą, metodę systemową oraz metodę historyczną.

Wyniki

Dysproporcje pomiędzy obszarami rozwijającymi się dynamicznie, a terytoriami, które nie nadążają w rozwoju są zauważalne. Postępująca polaryzacja w tym zakresie wymaga analizy, w celu wyjaśnienia etiologii tego zjawiska. Przykład Wielkopolski oraz Warmii i Mazur wyraźnie pokazuje różnice w rozwoju regionu będącego regionem centralnym i peryferyjnym.

Wnioski

Wielkopolska oraz Warmia i Mazury charakteryzują się znacznymi różnicami w poziomie rozwoju regionalnego. Wynika to z wielu czynników. Istotną rolę odgrywają uwarunkowania historyczne oraz położenie geograficzne obu regionów. Kolejną grupą czynników jest specyfika regionów, na którą wpływają topografia, demografia, stopień urbanizacji oraz stan infrastruktury gospodarczej i drogowej. Analiza czynników etiologicznych może być punktem wyjścia do rozważań nad możliwościami niwelowania różnic regionalnych.

Authors: Krugiełka Agnieszka , Bartkowiak Grażyna , Knap-Stefaniuk Agnieszka , Straburzyński Grzegorz
Published: March 2024

Cel pracy

Przedmiotem rozważań autorów artykułu jest problematyka job crafting (JC) - kształtowania pracy, w relacji do postrzeganego stresu w pracy, wśród przedstawicieli zróżnicowanych grup zawodowych. Celem artykułu jest uzyskanie odpowiedzi na następujące pytania badawcze: Czy uczestniczące w badaniach grupy zawodowe różnią się między sobą pod względem (poszczególnych aspektów i łącznego wyniku) kształtowania pracy, stresu w pracy? Czy istnieje zależność między job craftingiem (kształtowaniem pracy) a poziomem postrzeganego stresu w pracy w badanych grupach?

Materiał i metody

W badaniach zastosowano zwalidowane kwestionariusze - The Job Crafting Questionnaire i Kwestionariusz Kształtowania Pracy. Poziom postrzeganego stresu badano korzystając z Kwestionariusza Postrzeganego Stresu w Pracy. W badaniach uczestniczyło 138 osób, posiadających wyższe wykształcenie. Cztery grupy respondentów (polscy i zagraniczni nauczyciele akademiccy, menadżerowie i specjaliści) nie różniły się między sobą zarówno pod względem parytetu płci jak i wieku i stażu pracy.

Wyniki

Badane grupy różnią się między sobą jedynie pod względem kształtowania pracy, natomiast nie występują między nimi statystycznie istotne różnice w postrzeganiu stresu w pracy. Ponadto, wykazano, że między poziomem job craftingu istnieje silna, odwrotnie proporcjonalna zależność, co oznacza, że możliwość kształtowania pracy współwystępuje z niższym poziomem postrzegania stresu.

Wnioski

Istnienie zależności między kształtowaniem pracy, a postrzeganym stresem zawodowym, w analizowanych grupach potwierdza znaczenie poczucia sprawczości i kontroli w zachowaniu równowagi psychicznej pracownika. Uzyskane dane mają wymiar aplikacyjny i wskazują na możliwość podjęcia szeregu działań podnoszących poziom dobrostanu pracownika i przyczyniających się do rozwoju organizacji.

Authors: Bochniarz Agnieszka , Kirenko Janusz
Published: March 2024

Cel pracy

Celem badań było zdiagnozowanie poczucia koherencji młodzieży wychowywanej przez samotne matki w kontekście posiadanych przez nią dyspozycji podmiotowych: samooceny, wartości i wsparcia społecznego.

Materiał i metody

Materiał badawczy uzyskano za pomocą metody sondażu diagnostycznego, w skład którego weszły: Kwestionariusz Orientacji Życiowej (SOC-29) Antonovsky’ego, Skala Samooceny (TSCS) Fittsa, Kwestionariusz Wsparcia Społecznego (NSSQ) Norbeck oraz Portretowy Kwestionariusz Wartości (PVQ) Schwartza.

Wyniki

W skonstruowanym modelu ścieżkowym, na podstawie wcześniejszych analiz regresji wielorakich krokowych, uzyskane konfiguracje predykcyjne przyjmowały zróżnicowany charakter znaczeniowy. Psychospołecznymi predyktorami poczucia koherencji młodzieży wychowywanej przez samotne matki były wskaźniki wsparcia społecznego, wartości i samooceny: wsparcie pomocowe i funkcjonalne, wartości bezpieczeństwa, tradycji i władzy oraz ja osobiste.

Wnioski

Wysoki poziom poczucia koherencji istotnie i pozytywnie koreluje z doświadczaniem wsparcia pomocowego przez młodzież wychowywaną przez samotne matki. Otrzymywana pomoc w wymiarze materialnym wraz z preferowaniem wartości tradycji i władzy sprzyja lepszemu przystosowaniu się badanych do zmieniającej się rzeczywistości. Natomiast im silniejsze wsparcie o charakterze funkcjonalnym, wyższa ocena własnej osoby oraz wyższy poziom bezpieczeństwa społecznego i osobistego młodzieży wychowywanej przez samotne matki, tym w mniejszym stopniu angażuje się ona w działania mające na celu poprawę swojej sytuacji życiowej i trudniej radzi sobie ze stresem. Z punktu widzenia praktyki edukacyjnej uzyskane wyniki badań mogą posłużyć do planowania i projektowania działań wzmacniających dyspozycje podmiotowe oraz wspierających funkcjonowanie młodych ludzi z rodzin niepełnych.

Published: March 2024

Cel pracy

Celem badań była ocena znaczenia działań realizowanych w ramach zielonej strategii personalnej dla budowania wizerunku pracodawcy na rynku pracy.

Materiał i metody

Badanie zostało przeprowadzone z wykorzystaniem metody sondażu diagnostycznego na próbie 154 respondentów będących studentami UPH w Siedlcach w okresie od maja do czerwca 2023 r. z użyciem ankiety internetowej utworzonej na platformie Google Forms.W toku badań podjęto próbę odpowiedzi na pytanie, które z praktyk zielonej strategii personalnej są postrzegane przez kandydatów jako atrakcyjne oraz jaki jest zakres ich realizacji w praktyce?

Wyniki

W toku badań ustalono, że zielony wizerunek organizacji jest ważny w procesie pozyskiwania przedstawicieli pokolenia Z.
Kluczowe znaczenie w procesie przyciągania nowych pracowników ma kształtowanie proekologicznych zachowań w miejscu pracy, oferowanie przez pracodawców szkoleń podnoszących kompetencje ekologiczne, nagradzanie zaangażowania w realizację ekologicznych projektów oraz motywowanie do rozwoju zielonych kompetencji. Jednoczenie praktyki związane z zieloną polityką personalną wciąż stosunkowo rzadko stosowane są w praktyce.

Wnioski

Uzyskane wyniki pozwalają na sformułowanie wniosku, że polscy menedżerowie nie wykorzystują w pełni potencjału, jaki posiada zielona strategia personalna w procesie budowania wizerunku organizacji na rynku pracy. Może to wynikać z braku świadomości znaczenia takiej strategii wśród menedżerów bądź czynników finansowych. Uzyskane wyniki mogą być użyteczne dla kadry zarządzającej w procesie projektowania działań ukierunkowanych na poprawę efektywności zarządzania wizerunkiem pracodawcy na rynku pracy.
Legal nature of the annulment sanction indicated in art. 9 item 1 of the Act on shaping the agricultural system in connection with the amendment to this Act
Authors: Zięty Jakub Jan , Kudrzycka-Szypiłło Aleksandra
Published: March 2024

Cel pracy

Charakter sankcji nieważności uregulowanej w art. 9 u.k.u.r. budzi szereg wątpliwości zarówno doktryny jak i orzecznictwa. Pomimo ostatniej nowelizacji przepisu wątpliwości te nie zostały usunięte. Celem artykułu jest próba zdefiniowania charakteru prawnego sankcji nieważności z art. 9 u.k.u.r.

Materiał i metody

W publikacji zastosowano metodę dogmatyczno-prawną jako właściwą do analizy przepisów prawa. W niewielkim zakresie niezbędnym do wskazania zmian jakie nastąpiły na przestrzeni ostatniego roku zastosowano metodę historycznoprawną.

Wyniki

Wyniki przeprowadzonych badań wskazują, że sankcja nieważności z art. 9 u.k.u.r. swoją konstrukcją przypomina nieważność z art. 58 k.c., lecz nie posiada cech nieważności bezwzględnej. Nadto bezprzedmiotowe byłoby powtarzanie sankcji, która została uregulowana w art. 58 k.c. i ma zastosowanie w prawie cywilnym jako przepis podstawowy. Skoro ustawodawca zdecydował się na powtórzenie i osobne uregulowanie sankcji nieważności w u.k.u.r. jej charakter należy rozumieć w sposób odmienny.

Wnioski

Przeprowadzone analizy i zaprezentowane wyniki dają asumpt do wskazania na konieczność doprecyzowania charakteru sankcji jaką ustawodawca zastosował w art. 9 ustawy o kształtowaniu ustroju rolnego. Zmiany mogły by w sposób właściwy pozwolić na prawidłowe stosowanie sankcji.
2022 NAPS Presidential Address: How Shaky a Foundation: The Apostolic Fathers
Authors: Jefford Clayton N.
Published: March 2024

Abstract: The advent of canonized texts in the post-Constantinian church led to the widespread assumption that specifically approved literature reflected general Christian orthodoxy. The danger that non-canonical literature posed to this process was to provide an avenue by which quasi-acceptable views could enter ecclesiastical theology via courses such as catechetical instruction and teaching from episcopal leaders. The Apostolic Fathers reflect this very process. Those who study these writings today are warned not simply to presume specific locations or dates for their use in antiquity since many such writings came to influence the growth of ecclesiastical power and ideas within contexts that have been lost to our knowledge. This paper counsels researchers not to take such literature lightly nor to presume the influence it may have had within the early patristic sphere.
Temporal dynamics of surface phonon polaritons in polar dielectric nanoparticles with nonlocality
Authors: Zhang Ye , Xu Fengchuan , Huang Yang , Gao Lei
Published: March 2024

Surface phonon polaritons (SPhPs) supported by polar dielectrics have been a promising platform for nanophotonics in mid-infrared spectral range. In this work, the temporal dynamic behavior of polar dielectric nanoparticles without (or with) spatial dispersion/nonlocality driven by the ultrashort Gaussian pulses is carried out. We demonstrate that three possible scenarios for the temporal evolutions of the dipole moment including ultrafast oscillations with the decay, exponential decay, and keeping a Gaussian shape exist, when the pulse duration of the incident field is much shorter than, similar to, and much longer than the localized SPhP lifetime. Once the nonlocal effect is considered, the oscillation period becomes large slightly, and the exponential decay turns fast. Furthermore, nonlocality-induced novel temporal behavior is found such as the decay with long-period oscillations when the center frequency of the incident pulse lies at the frequency of adjacent longitudinal resonant modes. The positive and negative time-shifts of the dielectric response reveal that the excitation of the dipole moment will be delayed or advanced. These temporal evolutions can pave the way towards potential applications in the modulation of ultrafast signals for the mid-infrared optoelectronic nanodevices.
Human myiasis in Sub-Saharan Africa: A systematic review
Authors: Jallow Binta J. J. , Gassara Goudja , Bajinka Ousman , Luo Yifei , Liu Mandie , Cai Jifeng , Huang Jingjing , Meng Fanming
Published: March 2024

Background

Human myiasis is a parasitic dipteran fly infestation that infects humans and vertebrates worldwide. However, the disease is endemic in Sub-Saharan Africa and Latin America. In Sub-Saharan Africa, it is under-reported and therefore its prevalence is unknown. This systematic review aims to elucidate the prevalence of human myiasis, factors that influence the infection, and myiasis-causing fly species in SSA. The review also dwelled on the common myiasis types and treatment methods of human myiasis.

Methods

Here, we collect cases of human myiasis in Sub-Saharan Africa based on literature retrieved from PubMed, Google Scholar and Science Direct from 1959 to 2022. A total of 75 articles and 157 cases were included in the study. The recommendations of PRISMA 2020 were used for the realization of this systematic review.

Results

In total, 157 cases of human myiasis in SSA were reviewed. Eleven fly species (Cordylobia anthropophaga,Cordylobia rodhaini,Dermatobia hominis,Lucilia cuprina,Lucilia sericata,Oestrus ovis,Sarcophagaspp.,Sarcophaga nodosa,Chrysomya megacephala,Chrysomya chloropygaandClogmia albipuntum) were found to cause human myiasis in SSA.Cordylobia anthropophagawas the most prevalent myiasis-causing species of the reported cases (n = 104, 66.2%). More than half of the reported cases were from travelers returning from SSA (n = 122, 77.7%). Cutaneous myiasis was the most common clinical presentation of the disease (n = 86, 54.7%). Females were more infected (n = 78, 49.6%) than males, and there was a higher infestation in adults than young children.

Conclusion

The findings of this study reveals that international travelers to Sub-Saharan Africa were mostly infested therefore, we recommend that both international travelers and natives of SSA be enlightened by public health officers about the disease and its risk factors at entry points in SSA and the community level respectively. Clinicians in Sub-Saharan Africa often misdiagnose the disease and most of them lack the expertise to properly identify larvae, so we recommend the extensive use of molecular identification methods instead.
Enhancing rural B&B management through machine learning and evolutionary game: A case study of rural revitalization in Yunnan, China
Authors: Jin Wiseong , Min Kwisik , Hu Xufang , Li Shengchao , Wang Xueqin , Song Bodong , Li Chengmeng
Published: March 2024

The rural B&B industry is a key component of rural tourism, local economic development, and the wider rural revitalization strategy. Despite the abundance of tourism resources in Yunnan, the B&B sector faces significant challenges. It is therefore imperative to accurately identify the most pressing issues within the current B&B industry and formulate appropriate solutions to advance Yunnan’s rural revitalization efforts. This study uses recent reviews of rural B&Bs on Ctrip.com and employs machine learning techniques, including Bert, CNN, LSTM, and GRU, to identify the key management challenges currently facing Yunnan’s rural B&B industry. An analysis is then conducted to identify the key stakeholders involved in the process of improving the management of Yunnan’s B&Bs. To assess the willingness of each stakeholder to support the improvement of the rural B&B industry, this paper establishes a three-party evolutionary game model and examines the dynamic evolutionary process of management improvement within Yunnan’s rural B&B industry. Two scenarios of evolutionarily stable strategies are analyzed, and parameters impacting stakeholders’ strategy choices are simulated and evaluated. The results show that: i) Improving the "human factor" is the top priority for the current management improvement because tourists are most concerned about the emotional experience. Operators need to focus on improving service attitude and emotional experience; ii) The main stakeholders in the current management optimization process of Yunnan B&Bs are the local government, B&B operators, and tourists. Under appropriate conditions, the evolutionarily stable strategy of (1, 1, 1) is reachable. iii) variables such as additional costs, tourists’ choice preferences, and government penalties significantly affect the strategy choices of stakeholders, especially B&B operators. This paper offers effective strategies for improving B&B management that can benefit the government, B&B operators, and tourists, and ultimately contribute to the promotion of quality rural revitalization. The paper not only identifies focal areas for improving B&B management in rural Yunnan, but also provides an in-depth understanding of stakeholder dynamics. As a result, it provides valuable insights to further the cause of quality rural revitalization.
Effects of partial demand uncertainty reduction on private equity financing in small and medium-sized enterprises: A supply chain perspective
Authors: Deng Jie , Yao Li , Chen Mengyi , He Qingsong
Published: March 2024

The effect of demand uncertainty reduction (DUR) on supply chain management has received tremendous attention. From a financial perspective, studying the impact of DUR is equally significant. This study explores the relationship between DUR and private equity (PE) financing in retail enterprises within a supply chain, which comprises a dominant supplier and a subordinate retailer. This article establishes decision models for a retailer backed by PE under three market demand conditions: range, mean, and range with mean. The study further investigates the impact of partial demand uncertainty reduction (PDUR) on the retailer and PE through comparative analysis of these scenarios. To address incomplete market demand information during the decision-making process, the study employs the minimax regret criterion to construct and solve the model. An intriguing finding of this study is that contrary to intuition, PDUR not only fails to promote PE but also reduces the retailer’s willingness to finance and decreases the asset size for both the retailer and PE. In addition, the better the growth potential for the retail enterprise, the more severe the negative impact brought about by PDUR. Moreover, the impact of PDUR on supplier and supply chain performance is two-fold. PDUR based on range information has a negative impact on the expected profit of the supplier and the supply chain, while PDUR based on mean information has a positive impact on their expected profit.
Evaluation and optimization of outdoor wind environment in block based on space syntax and CFD simulation
Authors: Cao Peng , Li Wenhui
Published: March 2024

The wind environment quality at the height of pedestrians can significantly affect the thermal comfort and physical and mental health of pedestrians, promote the diffusion of air pollutants and inhibit the formation of urban heat island effect, and has been paid more and more attention in the field of urban and rural planning. This paper takes Jianlan Road commercial pedestrian Street as an example to maximize the thermal comfort of pedestrians. Based on CFD numerical simulation technology and space syntax theory, the pedestrian wind environment of the accessible space of the block is selected for quantitative research. Through numerical simulation, the influence of block spatial form on the wind environment at pedestrian height under the initial condition of uniform air flow is analyzed, and some suggestions are put forward for the optimization of block spatial form. Finally, the block optimization scheme is verified and simulated. The visualization results show that the wind environment quality of the optimized high-accessibility space is significantly improved, the proportion of comfort zone is increased from 58.2% to 86%, and the static wind rate is reduced from 41.8% to 14%. The wind environment optimization effect is obvious.
Labor market segmentation and the gender wage gap: Evidence from China
Authors: Li Mingming , Tang Yuan , Jin Keyan
Published: March 2024

Although the Chinese government has implemented a variety of measures, the gender wage gap in 21st century China has not decreased. A significant body of literature has studied this phenomenon using sector segmentation theory, but these studies have overlooked the importance of the collective economy beyond the public and private sectors. Moreover, they have lacked assessment of the gender wage gap across different wage groups, hindering an accurate estimation of the gender wage gap in China, and the formulation of appropriate recommendations. Utilizing micro-level data from 2004, 2008, and 2013, this paper examines trends in the gender wage gap within the public sector, private sector, and collective economy. Employing a selection bias correction based on the multinomial logit model, this study finds that the gender wage gap is smallest and most stable within the public sector. Furthermore, the private sector surpasses the collective economy in this period, becoming the sector with the largest gender wage gap. Meanwhile, a recentered influence function regression reveals a substantial gender wage gap among the low-wage population in all three sectors, as well as among the high-wage population in the private sector. Additionally, employing Brown wage decomposition, this study concludes that inter-sector, rather than intra-sector, differences account for the largest share of the gender wage gap, with gender discrimination in certain sectors identified as the primary cause. Finally, this paper provides policy recommendations aimed at addressing the gender wage gap among low-wage groups and within the private sector.
Ethical care in patients with Covid-19: A grounded theory
Authors: Azimi Hamideh , Rezapour-Nasrabad Rafat , Borhani Fariba , Sadat Hoseini Akram Sadat , Bolourchifard Fariba
Published: March 2024

Background

Providing ethical care during the Covid-19 pandemic has become an inevitable challenge due to facing limitations such as fear of contracting the disease, lack of equipment and emergence of ethical conflicts; So that there is no clear picture of how to provide ethical care for patients with Covid-19. The study aimed to explain the ethical care process of patients with Covid-19.

Method

This qualitative study was conducted in 2021–2023 using the grounded theory research method. Data were collected through conducting 21 semi-structured interviews with 19 participants (16 staff nurses, and 3 supervisor). Sampling was started purposively and continued theoretically. Data analysis was performed by the method proposed by Strauss and Corbin.

Results

The results indicated that starting the process with a problem means a challenge of how to do the right or correct thing for the patient. This process is driven by the feeling of duty and inner commitment to do the right thing. The sense of responsibility or commitment is directly related to the degree of faith in a person. The actions that a nurse takes to fulfill her sense of commitment is called the faith-based behavior process. The process of behavior based on faith is done through two steps. Attaining the satisfaction of God and as well as the satisfaction of one’s conscience is the nurses’ ultimate goal of doing the right work and being committed.

Conclusion

The process of ethical care of patients with Covid-19 can be different according to the degree of faith and environmental conditions. A higher level of faith and more helpful environmental conditions, the greater the nurse’s inner commitments in the first and second steps, as a result, the satisfaction of God and conscience will be greater.
Effects of the Momentum project on postpartum family planning norms and behaviors among married and unmarried adolescent and young first-time mothers in Kinshasa: A quasi-experimental study
Authors: Gage Anastasia J. , Wood Francine E. , Gay Rianne , Akilimali Pierre
Published: March 2024

This study evaluated the effect of Momentum–an integrated family planning, maternal and newborn health, and nutrition intervention–on postpartum family planning norms and behaviors among ever married and never-married first-time mothers age 15–24 in Kinshasa, Democratic Republic of the Congo. Using data collected in 2018 and 2020, we conducted an intent-to-treat analysis among 1,927 first-time mothers who were about six-months pregnant at enrollment. Difference-in-differences models were run for panel data and treatment effects models with inverse-probability weighting for endline-only outcomes. Average treatment effects (ATE) were estimated. Momentum had positive effects on partner discussion of family planning in the early postpartum period (ever married 15–19: ATE = 0.179, 95% CI = 0.098, 0.261; never married 15–19: ATE = 0.131, 95% CI = 0.029, 0.232; ever married 20–24: ATE = 0.233, 95% CI = 0.164, 0.302; never married 20–24: ATE = 0.241, 95% CI = 0.121, 0.362) and discussion with a health worker, and on obtaining a contraceptive method in the early postpartum period, except among never married adolescents. Among adolescents, intervention effects on modern contraceptive use within 12 months of childbirth/pregnancy loss were larger for the never married (ATE = 0.251, 95% CI = 0.122, 0.380) than the ever married (ATE = 0.114, 95% CI = 0.020, 0.208). Full intervention exposure had consistently larger effects on contraceptive behaviors than partial exposure, except among ever married adolescents. Momentum had no effect on normative expectations about postpartum family planning use among adolescents, and on descriptive norms and personal agency among those who were never married. Results for normative outcomes and personal agency underscored the intersectionality between young maternal age and marital status. Future programs should improve personal agency and foster normative change in support of postpartum family planning uptake and tailor interventions to different age and marital status subsets of first-time mothers.
Clusters of longitudinal risk profile trajectories are associated with cardiometabolic diseases: Results from the population-based KORA cohort
Authors: Niedermayer Fiona , Schauberger Gunther , Rathmann Wolfgang , Klug Stefanie J. , Thorand Barbara , Peters Annette , Rospleszcz Susanne
Published: March 2024

Background

Multiple risk factors contribute jointly to the development and progression of cardiometabolic diseases. Therefore, joint longitudinal trajectories of multiple risk factors might represent different degrees of cardiometabolic risk.

Methods

We analyzed population-based data comprising three examinations (Exam 1: 1999–2001, Exam 2: 2006–2008, Exam 3: 2013–2014) of 976 male and 1004 female participants of the KORA cohort (Southern Germany). Participants were followed up for cardiometabolic diseases, including cardiovascular mortality, myocardial infarction and stroke, or a diagnosis of type 2 diabetes, until 2016. Longitudinal multivariate k-means clustering identified sex-specific trajectory clusters based on nine cardiometabolic risk factors (age, systolic and diastolic blood pressure, body-mass-index, waist circumference, Hemoglobin-A1c, total cholesterol, high- and low-density lipoprotein cholesterol). Associations between clusters and cardiometabolic events were assessed by logistic regression models.

Results

We identified three trajectory clusters for men and women, respectively. Trajectory clusters reflected a distinct distribution of cardiometabolic risk burden and were associated with prevalent cardiometabolic disease at Exam 3 (men: odds ratio (OR)ClusterII = 2.0, 95% confidence interval: (0.9–4.5); ORClusterIII = 10.5 (4.8–22.9); women: ORClusterII = 1.7 (0.6–4.7); ORClusterIII = 5.8 (2.6–12.9)). Trajectory clusters were furthermore associated with incident cardiometabolic cases after Exam 3 (men: ORClusterII = 3.5 (1.1–15.6); ORClusterIII = 7.5 (2.4–32.7); women: ORClusterII = 5.0 (1.1–34.1); ORClusterIII = 8.0 (2.2–51.7)). Associations remained significant after adjusting for a single time point cardiovascular risk score (Framingham).

Conclusions

On a population-based level, distinct longitudinal risk profiles over a 14-year time period are differentially associated with cardiometabolic events. Our results suggest that longitudinal data may provide additional information beyond single time-point measures. Their inclusion in cardiometabolic risk assessment might improve early identification of individuals at risk.

Background

Majority of earlier studies have assessed the association between individual healthy eating index-2010 (HEI-2010) and the odds of breast cancer (BC). However, no study has been conducted on the effect of compliance with HEI-2010 and the odds of BC in the Iranian population with a large sample size. Therefore, we aimed to investigate the relationship between the HEI-2010 and the odds of BC in the Iranian population.

Method

This population-based case-control study included 350 newly diagnosed cases of BC and 700 healthy controls randomly selected from adult women. HEI-2010 was examined using validated questionnaires. The adherence to HEI-2010 among the participants was divided into four categories. The general characteristics of the participants in the quartiles of the HEI score for categorical variables and continuous variables were evaluated using chi-square and one-way analysis of variance, respectively. Also, using logistic regression analysis, dietary intakes were evaluated in HEI score quartiles. Also, confounding variables were adjusted in different models.

Result

People with the highest HEI score had 60% lower odds of BC (OR: 0.40; 95% CI: 0.27, 0.57) than those with the lowest score among post-menopause women. After controlling for age and energy intake, individuals with the highest HEI score were 78% less likely to have BC compared with those with the lowest score (OR: 0.22; 95% CI: 0.14, 0.33). Adjustments for other potential confounders including demographic factors made the association stronger (OR: 0.21; 95% CI: 0.13, 0.32). This association remained significant even after taking BMI into model (OR: 0.27; 95% CI: 0.17, 0.43).

Conclusion

Finally, in this study we found an association between HEI-2010 and odds of breast cancer. This association was particularly seen in postmenopausal women. No significant association was found between adherence to HEI-2010 and odds of BC among pre-menopausal.

This study investigated the relationship between autistic traits, expressiveness, readability (both actual and perceived), social favourability, and likability. Sixty participants designated as ‘targets’ were video recorded in a range of social scenarios and their autistic traits were measured using the Autism Spectrum Quotient. The videos were then shown to 106 new participants designated ‘perceivers’, who were split into three groups to make judgments related to readability, expressiveness, and social favourability respectively. Mediation analyses revealed that autistic traits negatively impacted both perceived likeability and social favourability, mediated by lowered expressiveness. Autistic traits also directly impacted readability, which was not mediated by expressiveness. The findings show how the level of autistic traits of a target can influence how they are socially perceived by others.

The water resource tax reform played an important role in promoting sustainable development in China. Subsequent to the seven-year reform, the effectiveness evaluation of the policy in each pilot area and the exploration of the optimization path directly affected the promotion of water resource tax policy and the improvement of water use efficiency. Therefore, the theoretical framework of the water resource tax policy field was constructed to examine the mechanism of the three subsystems of policy scenario, policy orientation, and policy effect; fuzzy-set qualitative comparative analysis (fsQCA) was then used to evaluate and quantitatively compare the policy implementation effect and policy path in each pilot area, with emphasis put on three policy orientations, i.e., the decision and decomposition effect of policy goals, the selection and im plementation effect of policy tools, and the policy supervision and security effect. As shown by the research results: ① the water resource tax reform had effectively improved the efficiency of water resource utilization in the pilot areas; ② three pilot models of water resource tax policy had been extracted, namely the policy goal and tool-driven model centering on a single dimension of the policy field, the implementation-supervision dual drive model emphasizing the supervision and security effect of the policy, and the three-dimensional policy orientation linkage model that focused on the synergistic effect of the policy field; ③ strong heterogeneity existed in water resource tax policy implementation paths and effects in each pilot area. Accordingly, regional heterogeneity could be considered in the process of reform to construct institutionalized, precise, and differentiated reform implementation methods from the perspective of the policy field.

Over the last decade, the global population of refugees and other migrants in need of international protection (MNP) has more than doubled. Despite their rapid growth, panel data collection among MNP remains rare, leaving scholars with few data sources to draw on to understand dynamic changes in their social, economic, legal, or health circumstances. With that paucity in mind, we developed and piloted the Encuesta de Refugiados: Experiencias Sociales y Salud (ERESS), a weekly panel survey conducted with MNP living in Costa Rica. To our knowledge, this panel constitutes one of the first weekly surveys with MNP anywhere in the world. Here, we describe the overall study design, sample recruitment and retention, and key descriptive findings. We show that retaining demographically and socioeconomically diverse MNP in intensive panel surveys is possible and that doing so reveals valuable insights into dynamic changes in their incorporation, family dynamics, and health and wellbeing. By offering a summary of our field experiences and central methodological findings, we highlight the potential benefits and challenges of collecting intensive panel data with MNP, as scholars increasingly seek to understand their pre- and post-migration trajectories and relationships between the two.

The rheological properties of asphalt can well reflect its road performance, but the rheological properties of warm mix high viscosity asphalt (HVA) are unclear. In order to study the effect of warm mixing agent on rheological properties of HVA, two kinds of warm mixing agent EC120 (EC) and Evotherm M1 (M1) were selected to prepare warm mix HVA. The rheological properties of warm mix HVA at high temperature (135~195°C), medium temperature (0~80°C) and low temperature (-6~18°C) were studied by Brinell rotary viscosity test, dynamic shear rheological test (including temperature scanning, frequency scanning, linear amplitude scanning) and bending beam rheological test. The test results show that both EC and M1 have good viscosity reduction effect on HVA at high temperature, and can effectively reduce the construction temperature. At medium temperature, M1 can effectively improve the fatigue resistance of HVA, and the fatigue life can be increased by about 30% when the dosage is 0.6%. EC can increase the rutting factor of HVA and improve its resistance to deformation, but it will reduce its fatigue performance. When the dosage is 4%, the fatigue life will be reduced by about 9%. At low temperature, M1 can reduce the creep stiffness S, increase the creep rate m, and improve the low temperature performance of HVA, while EC has the opposite effect, weakening the low temperature performance of HVA. The results are helpful to understand the rheological properties of warm mix HVA and promote its application.

Acanthamoeba castellanii is infected with diverse nucleocytoplasmic large DNA viruses. Here, we report the co-isolation of 12 viral strains from marine sediments in Uranouchi Inlet, Kochi, Japan. Based on the morphological features revealed by electron microscopy, these isolates were classified into four viral groups including Megamimiviridae, Molliviridae, Pandoraviridae, and Pithoviridae. Genomic analyses indicated that these isolates showed high similarities to the known viral genomes with which they are taxonomically clustered, and their phylogenetic relationships were also supported by core gene similarities. It is noteworthy that Molliviridae was isolated from the marine sediments in the Japanese warm temperate zone because other strains have only been found in the subarctic region. Furthermore, this strain has 19 and 4 strain-specific genes found in Mollivirus sibericum and Mollivirus kamchatka, respectively. This study extends our knowledge about the habitat and genomic diversity of Molliviridae.
