Since then, almost 100 years later, we are now facing another pandemic of the SARS-CoV2 virus (Covid-19), which is still endemic to this day. As technology evolved during those 100 years, an effective vaccine for Covid-19 was produced within only a year, a huge feat. But, unfortunately, due to its fast development, another force would arise limiting the impact of the vaccine: Vacccine hesitancy and anti-vaxxers, which John Hopkins and the World Health Organization call the biggest current threat to global health. From politics to social media, it is clear that there has been a rapid spread of misinformation, resulting in hesitancy, especially from sociopolitically motivated people popularly referred to as antivaccers. However, a second group of vaccine-hesitant people have also emerged, who are uneducated and remain undecided about vaccination mostly due to safety concerns. They come under the massive influence of anti-vaxxers and anti-vaccine propaganda through social media and politicians, which often make bold claims and huge headlines. To combat vaccine hesitancy, it is crucial that we debunk these conspiracy theories and misinformation that so many believe in, with factual, data-based information. Actively spreading correct information about the vaccines, such as disclosing the rigorous developmental processes and validation of safety data by the FDA, assurance for unlikeliness of getting a lethal side effect along with tremendous health benefits, will encourage people to safe vaccination against Covid-19 and other potentially infectious diseases in future. This article discusses the role of anti-vaxxers and vaccine hesitancy groups, electronic social media, and politics in vaccine hesitancy among people. It describes the strategies to combat the roadblocks in the vaccination programs and health benefits, offered by recent advances in scientific and technological developments.展开更多

The study evaluated factors that may contribute to hesitancy towards IPV. Methods: Questionnaire adapted from the model developed by the Strategic Advisory Group of Experts Working Group (SAGE WG) was used to assess the factors among 408 parents. The evaluation was under the 3 Cs: Confidence, Complacency and Convenience. Questions were scored on Likert 4-unit-scale system. The data were analyzed using SPSS and, multivariate analysis was used to further test individual significant variables. Results: Overall, Complacency (2.29) and Convenience (2.11) domains were more pro-vaccine hesitant, than Confidence (1.83) domain. However, none was significantly associated with likelihood of a parent’s hesitancy towards IPV vaccination. But certain individual questions: competence of vaccinators (p = 0.04), confidence that their child will not to be infected with poliomyelitis even when not vaccinated (p = 0.03) and, willingness to vaccinate with IPV when OPV is still in use (p = 0.01) were significantly associated with vaccine hesitancy. Conclusions: None of the factors can individually influence acceptance of IPV. However, competence of vaccinators, parental belief and availability of close alternative influenced parental decision to vaccinate.展开更多

In Saudi Arabia, public support for immunisation programmes is generally high and well received. However, the benefits of vaccines are often not fully known or appreciated. When public discussion on vaccine safety, quality or efficacy occurs, very often misinformation creeps into the debate through the internet and other media sources, significantly weakening immunisation programmes. Vaccine hesitancy is a concept frequently used in the discourse around vaccine acceptance. This study reflects on the factors associated with vaccine hesitancy, through a study focusing on knowledge, attitudes and beliefs among parents of young children. Methods: A cross-sectional study was carried out in seven primary schools in Makkah city, Saud Arabia. Data were collected in 2017 through a computer based-survey administered to 100 parents with children aged between 2 months and 17 years of age. Questionnaire responses were analysed using Minitab. Results: Many parents (with a total of 292 children) agreed on the importance of vaccinations, to protect their children’s health and to prevent the spread of diseases in the community. Most parents (68.7%, P Discussion and Conclusions: Vaccine hesitancy is a common problem in Makkah, Saudi Arabia. Further research will be needed to better understand when, how and why these beliefs are formed.展开更多

In the next step, it ex-tended the free vaccination campaign to include people above 60 and 50 years of age re-spectively. The drive is now open to all citizens >18 years of age. There is a significant re-luctance to get vaccinated even though the government has provided it free of cost. The project uses self-reporting method to assess reasons of vaccine hesitancy among Pakistanis and possible solutions to overcome this problem. Concern for serious side effects was the most common issue 154 (48.42%) reported among all groups of people, including the healthcare workers. The major sources of COVID-19 related information were television 117 (36.8%) and healthcare professionals 105 (33%). The participants reported that they can be convinced to get vaccinated if more published data related to vaccine efficacy and safety is available 118 (37.1%), they observe no side effect among vaccine recipients 90 (28.3%) or higher government officials get the same vaccine 39 (12.3%). Vigorous analysis and publication of data generated is paramount to increase the percentage of people being vaccinated. The healthcare professionals should share evidence-based knowledge related to vaccine efficacy and safety through television and social media to increase acceptance rates and hence, decrease mortality and morbidity from COVID-19 in Pakistan.展开更多

This cross-sectional study was conducted online with 1046 adults aged 18 and older. The Ok-Religious Attitude Scale (Islam) (ORASI) (8 items) and Thorson-Powell Death Anxiety Scale (TPDAS) (20 items) were used as data collection instruments. The data were analyzed using the Pearson chi-square test, Student’s t-test, and binary logistic regression. A p-value of 0.05). In binary logistic regression analysis, vaccine rejection was 7.19 times higher among single people, 50.55 times higher among workers and tradesmen, and 3.36 times higher among people who did not have COVID-19. As religiosity increased, the risk of vaccine refusal decreased 1.037-fold.展开更多

Purpose: To explore the reasons behind nurses’ hesitance to apply for midwifery specialization. The objectives of this study were to understand the challenges that lie in front of Omani nurses and the motivational factors to apply for a midwifery programme. Method: Exploratory qualitative study was conducted at the largest tertiary hospital in Oman. Purposive sampling was applied for participant recruitment. Face-to-face interviews and focus group discussions were used as data collection methods. The study included general nurses, nurses in charge working in the maternity unit as well as nurses whose applications were accepted for midwifery education. Qualified midwives were excluded. The data collection process yielded twenty-five nurses. The interview protocol highlighted the impact and perception of the midwifery specialization on nurses’ careers. Thematic analysis was employed for data analysis. Results: Three over-arching major themes were identified. These are 1) nurses’ perceptions about the nature of work in maternity wards, the nurses have positive perception toward working in maternity wards and labor room because of working exclusively with female patients and their babies 2) factors influencing the decision to study midwifery specialization, work overload, stress, lack of support from administration were the most common reason behind the nurses not to apply for midwifery specialization and 3) support and recommendations required for midwives, the nurses mentioned that their identity, promotions and support from the administration will encourage them to apply for midwifery specialization. Conclusion: One of the main reasons that hindered nurses from applying to midwifery specialization is the false belief that midwives cannot work outside the delivery suite (DS). The second reason was the stress that midwives encounter at DS, and this was perceived by general nurses who did not work at DS. These challenges could be mitigated by leadership support, midwifery profession identity, as well as financial recognition for the midwives.展开更多

文摘The hesitancy fuzzy graphs(HFGs),an extension of fuzzy graphs,are useful tools for dealing with ambiguity and uncertainty in issues involving decision-making(DM).This research implements a correlation coefficient measure(CCM)to assess the strength of the association between HFGs in this article since CCMs have a high capacity to process and interpret data.The CCM that is proposed between the HFGs has better qualities than the existing ones.It lowers restrictions on the hesitant fuzzy elements’length and may be used to establish whether the HFGs are connected negatively or favorably.Additionally,a CCMbased attribute DM approach is built into a hesitant fuzzy environment.This article suggests the use of weighted correlation coefficient measures(WCCMs)using the CCM concept to quantify the correlation between two HFGs.The decisionmaking problems of hesitancy fuzzy preference relations(HFPRs)are considered.This research proposes a new technique for assessing the relative weights of experts based on the uncertainty of HFPRs and the correlation coefficient degree of each HFPR.This paper determines the ranking order of all alternatives and the best one by using the CCMs between each option and the ideal choice.In the meantime,the appropriate example is given to demonstrate the viability of the new strategies.
文摘BACKGROUND The coronavirus disease 2019(COVID-19)pandemic posed new challenges in patient care worldwide.Vaccinations,which have proven efficacious in lowering the COVID-19 hospital burden,are still avoided by large populations.We,therefore,hypothesized that hospital care teams would have worse perceptions regarding the characteristics and care of patients with vaccine hesitancy.AIM To evaluate whether patient vaccine hesitancy affected the hospital care team(HCT)perceptions.METHODS We performed a prospective clinical study using structured questionnaires.We approached physicians and nurses with previous experience caring for COVID-19patients from 11 medical centers across Israel during the fourth COVID-19 surge(September and October 2021).The participants completed a questionnaire with the following parts:(1)Sociodemographic characteristics;(2)Assessment of anger(STAXI instrument)and chronic workplace stress(Shirom-Melamed burnout measure);and(3)Three tools to assess the effect of patient vaccine hesitancy on the HCT perceptions(the difficult doctor-patient relation questionnaire,the medical staff perception of patient’s responsibility questionnaire and the characterological derogation questionnaire).Results were evaluated according to each part of the questionnaire and the questionnaire as a whole.Associations between HCT perceptions and their baseline characteristics,anger or chronic workplace stress were assessed.RESULTS The HCT experienced their relationship with unvaccinated patients as more difficult(P<0.001,Cohen’s d=0.85),perceived unvaccinated patients as responsible for their medical condition(P<0.001,d=1.39)and perceived vaccinated patients as having a higher character value(P<0.001,d=1.03).Unvaccinated patients were considered selfish(P<0.001),less mature(P<0.001)and less satisfying to care for(P<0.001).The relationship with unvaccinated patients was more difficult among HCT with higher burnout(r=0.37,n=66,P=0.002).No correlations with baseline characteristics were found.All three study tools showed high internal consistency(αbetween 0.72 and 0.845).CONCLUSION Our results should raise awareness of the possible effects of vaccine hesitancy on HCT perceptions regarding unvaccinated patients.In order to minimize the potential negative impact on patient care,designated departments should promote specific patient-centered preparations.Further investigations should assess whether vaccine hesitancy directly affects patient quality of care.
文摘Objective:To examine the pattern of COVID-19 infection and vaccination,and to explore pregnant women’s willingness and reluctance to accept a booster dose of the COVID-19 vaccine.Methods:This was a cross-sectional,descriptive study with a convenient sample size using a structured questionnaire among pregnant women attending the gynecology and obstetrics department at Acıbadem Mehmet Ali Aydinlar Hospital,Istanbul,Türkiye.The Health Belief Model scale was used to assess the intention and reluctance to accept a booster dose of the COVID-19 vaccine.Results:A total of 145 participants,with a mean age of(33.5±4.8)years,and a gestational age of(30.9±7.3)weeks,were enrolled in this study.88.8%Received full doses of the Pfizer-BioNTech vaccination.47.8%Participants suffered from vaccine adverse effects.Health Belief Model demonstrated a significant finding of perceived susceptibility(P<0.001),perceived severity of COVID-19 complications(P<0.001),and perceived benefits regarding a booster COVID-19 vaccination(P<0.001).Conclusions:Most pregnant women who received the COVID-19 immunization express a significant intention to receive a booster dose,regardless of the adverse effects experienced from the previous doses.However,a small percentage of the study sample express hesitancy about receiving the booster dose.
文摘Decision-making(DM)is a process in which several persons concur-rently engage,examine the problems,evaluate potential alternatives,and select an appropriate option to the problem.Technique for determining order preference by similarity to the ideal solution(TOPSIS)is an established DM process.The objective of this report happens to broaden the approach of TOPSIS to solve the DM issues designed with Hesitancy fuzzy data,in which evaluation evidence given by the experts on possible solutions is presents as Hesitancy fuzzy decision matrices,each of which is defined by Hesitancy fuzzy numbers.Findings:we represent analytical results,such as designing a satellite communication network and assessing reservoir operation methods,to demonstrate that our suggested thoughts may be used in DM.Aim:We studied a new testing method for the arti-ficial communication system to give proof of the future construction of satellite earth stations.We aim to identify the best one from the different testing places.We are alsofinding the best operation schemes in the reservoir.In this article,we present the concepts of Laplacian energy(LE)in Hesitancy fuzzy graphs(HFGs),the weight function of LE of HFGs,and the TOPSIS method technique is used to produce the hesitancy fuzzy weighted-average(HFWA).Also,consider practical examples to illustrate the applicability of thefinest design of satellite communication systems and also evaluation of reservoir schemes.
文摘Last time the world faced a deadly pandemic was the H1N1 Spanish flu in 1918, which affected almost one third of the world’s population (500 million people). Since then, almost 100 years later, we are now facing another pandemic of the SARS-CoV2 virus (Covid-19), which is still endemic to this day. As technology evolved during those 100 years, an effective vaccine for Covid-19 was produced within only a year, a huge feat. But, unfortunately, due to its fast development, another force would arise limiting the impact of the vaccine: Vacccine hesitancy and anti-vaxxers, which John Hopkins and the World Health Organization call the biggest current threat to global health. From politics to social media, it is clear that there has been a rapid spread of misinformation, resulting in hesitancy, especially from sociopolitically motivated people popularly referred to as antivaccers. However, a second group of vaccine-hesitant people have also emerged, who are uneducated and remain undecided about vaccination mostly due to safety concerns. They come under the massive influence of anti-vaxxers and anti-vaccine propaganda through social media and politicians, which often make bold claims and huge headlines. To combat vaccine hesitancy, it is crucial that we debunk these conspiracy theories and misinformation that so many believe in, with factual, data-based information. Actively spreading correct information about the vaccines, such as disclosing the rigorous developmental processes and validation of safety data by the FDA, assurance for unlikeliness of getting a lethal side effect along with tremendous health benefits, will encourage people to safe vaccination against Covid-19 and other potentially infectious diseases in future. This article discusses the role of anti-vaxxers and vaccine hesitancy groups, electronic social media, and politics in vaccine hesitancy among people. It describes the strategies to combat the roadblocks in the vaccination programs and health benefits, offered by recent advances in scientific and technological developments.
文摘Diabetes mellitus is one of the most common comorbid conditions encountered in patients with severe acute respiratory syndrome coronavirus 2 infection accompanied by significantly increased mortality,prolonged hospital stay,and requirement of invasive mechanical ventilation.This review aims to present the effectiveness and safety profile of available coronavirus disease 2019(COVID-19)vaccines in people with diabetes as a potential cause of hesitancy for vaccination.Data from published research proves a robust immune response following immunization for COVID-19 in diabetic patients with substantial production of virus-neutralizing antibodies;however,the observed immune response was unequivocally weaker than that in individuals without diabetes.This observation was further enhanced by the findings that worse glycemic control was associated with more suppressed antibody production.In contrast,individuals with optimal glycemic control performed similarly to healthy controls.In addition to the need for strict glucose monitoring and adequate diabetes treatment,those findings reinforce the concept of diabetes-induced secondary immune deficiency and necessitate the application of booster doses to diabetic patients with priority.Nevertheless,after vaccination,reported adverse events were not different from those in the general population.No increase in severe adverse events was documented.While single case reports detected transient increases in blood glucose post-vaccination,more extensive trials could not replicate such a relationship.
文摘Background: Introduction of inactivated polio vaccine is imminent and may encounter the challenges that face new vaccines especially vaccine hesitancy. The study evaluated factors that may contribute to hesitancy towards IPV. Methods: Questionnaire adapted from the model developed by the Strategic Advisory Group of Experts Working Group (SAGE WG) was used to assess the factors among 408 parents. The evaluation was under the 3 Cs: Confidence, Complacency and Convenience. Questions were scored on Likert 4-unit-scale system. The data were analyzed using SPSS and, multivariate analysis was used to further test individual significant variables. Results: Overall, Complacency (2.29) and Convenience (2.11) domains were more pro-vaccine hesitant, than Confidence (1.83) domain. However, none was significantly associated with likelihood of a parent’s hesitancy towards IPV vaccination. But certain individual questions: competence of vaccinators (p = 0.04), confidence that their child will not to be infected with poliomyelitis even when not vaccinated (p = 0.03) and, willingness to vaccinate with IPV when OPV is still in use (p = 0.01) were significantly associated with vaccine hesitancy. Conclusions: None of the factors can individually influence acceptance of IPV. However, competence of vaccinators, parental belief and availability of close alternative influenced parental decision to vaccinate.
文摘Introduction: Vaccination provides health and economic benefits to the individual and to society. In Saudi Arabia, public support for immunisation programmes is generally high and well received. However, the benefits of vaccines are often not fully known or appreciated. When public discussion on vaccine safety, quality or efficacy occurs, very often misinformation creeps into the debate through the internet and other media sources, significantly weakening immunisation programmes. Vaccine hesitancy is a concept frequently used in the discourse around vaccine acceptance. This study reflects on the factors associated with vaccine hesitancy, through a study focusing on knowledge, attitudes and beliefs among parents of young children. Methods: A cross-sectional study was carried out in seven primary schools in Makkah city, Saud Arabia. Data were collected in 2017 through a computer based-survey administered to 100 parents with children aged between 2 months and 17 years of age. Questionnaire responses were analysed using Minitab. Results: Many parents (with a total of 292 children) agreed on the importance of vaccinations, to protect their children’s health and to prevent the spread of diseases in the community. Most parents (68.7%, P Discussion and Conclusions: Vaccine hesitancy is a common problem in Makkah, Saudi Arabia. Further research will be needed to better understand when, how and why these beliefs are formed.
文摘The government of Pakistan started vaccination campaign for the frontline healthcare pro-viders, as they are more likely to be exposed to COVID-19 patients. In the next step, it ex-tended the free vaccination campaign to include people above 60 and 50 years of age re-spectively. The drive is now open to all citizens >18 years of age. There is a significant re-luctance to get vaccinated even though the government has provided it free of cost. The project uses self-reporting method to assess reasons of vaccine hesitancy among Pakistanis and possible solutions to overcome this problem. Concern for serious side effects was the most common issue 154 (48.42%) reported among all groups of people, including the healthcare workers. The major sources of COVID-19 related information were television 117 (36.8%) and healthcare professionals 105 (33%). The participants reported that they can be convinced to get vaccinated if more published data related to vaccine efficacy and safety is available 118 (37.1%), they observe no side effect among vaccine recipients 90 (28.3%) or higher government officials get the same vaccine 39 (12.3%). Vigorous analysis and publication of data generated is paramount to increase the percentage of people being vaccinated. The healthcare professionals should share evidence-based knowledge related to vaccine efficacy and safety through television and social media to increase acceptance rates and hence, decrease mortality and morbidity from COVID-19 in Pakistan.

文摘Background:Despite the United States(US)having an abundant supply of COVID-19 vaccines,vaccination rates lag behind other high-income countries,suggesting that vaccine hesitancy and attitudes play a greater role in public health measures than pure supply and access.With the acknowledgment that vaccination attitudes and status may or may not be correlated,this study examined COVID-19 vaccine hesitancy among vaccinated US adults by asking:(1)What is the prevalence of COVID-19 vaccine hesitancy among the vaccinated?(2)Does COVID-19 vaccine hesitancy vary across sociodemographic characteristics?(3)Does COVID-19 vaccine hesitancy vary by healthcare access and influenza vaccination over the past 5 years?Methods:Data were collected through an online survey of 2022 US adults with a final analytic sample of 1383 vaccinated respondents.Results:Overall,48.8%of vaccinated adults reported some level of hesitancy,while a slight majority reported they were“not at all hesitant”.Younger respondents,women,and Black and American Indian or Alaska Native participants had greater adjusted odds of being more hesitant towards receiving the COVID-19 vaccine.Respon-dents who had a primary care physician had greater adjusted odds than those who did not have a primary care physician of being more hesitant towards receiving the COVID-19 vaccine.Conclusions:This is the first population-based national sample study examining COVID-19 vaccine hesitancy among vaccinated individuals from subgroups of distinctive backgrounds in order to inform targeted strategies for reducing vaccine hesitancy.Findings can assist in efforts to increase vaccination rates and also decrease vaccine hesitancy at the national level.

文摘Current discussions of the social phenomenon of“vaccine hesitancy”with regard to Covid-19 provide an opportunity to use hesitancy as a means to shift thinking about untimely and delayed responses to forecasts of hydrometeorological hazards.Hesitancy,that is,provides a paradigm through which such regrettably delayed responses to hydromet hazards might be better understood and effectively addressed.Without exaggeration,just about every hydromet event provides an example of how hesitancy hinders individual,community,and national government risk-reducing preventive and mitigative responses to forecasts of foreseeable,relatively near-term climate,water,or weather hazards.Reasons for such hesitancy(for vaccine and forecast use alike)include—among others—lack of trust in the science,lack of confidence in government,and persistent concern about the uncertainties that surround forecasting—both meteorological and public health.As such,a better understanding of the causes that lead to individual and group hesitancy can better inform hydromet forecasters and affected communities about ways in which beneficial actions in response to timely forecasts are often delayed.This better understanding will facilitate,where necessary,targeted interventions to enhance the societal value of forecasting by reducing this long-observed challenge of“forecast hesitancy.”First,this article focuses on incidents of“vaccine hesitancy”that,for various reasons,people around the world are even now experiencing with regard to several now-available,and confirmed efficacious,Covid-19 vaccines.Reports of such incidents of indecisiveness first increased dramatically over the first few months of 2021,despite the strong scientific confidence that vaccination would significantly lower personal risk of contracting as well as spreading the virus.After,the notion of forecast hesitancy with regard to hydrometeorological hazards is discussed.
文摘Hydrogen is the new age alternative energy source to combat energy demand and climate change.Storage of hydrogen is vital for a nation’s growth.Works of literature provide different methods for storing the produced hydrogen,and the rational selection of a viable method is crucial for promoting sustainability and green practices.Typically,hydrogen storage is associated with diverse sustainable and circular economy(SCE)criteria.As a result,the authors consider the situation a multi-criteria decision-making(MCDM)problem.Studies infer that previous models for hydrogen storage method(HSM)selection(i)do not consider preferences in the natural language form;(ii)weights of experts are not methodically determined;(iii)hesitation of experts during criteria weight assessment is not effectively explored;and(iv)three-stage solution of a suitable selection of HSM is unexplored.Driven by these gaps,in this paper,authors put forward a new integrated framework,which considers double hierarchy linguistic information for rating,criteria importance through inter-criteria correlation(CRITIC)for expert weight calculation,evidence-based Bayesian method for criteria weight estimation,and combined compromise solution(CoCoSo)for ranking HSMs.The applicability of the developed framework is testified by using a case example of HSM selection in India.Sensitivity and comparative analysis reveal the merits and limitations of the developed framework.

文摘Monkeypox(mpox)has been a public health emergency of international concern that emerged in mid-2022 and has spread to 110 countries.The clinical findings of the disease vary according to the seriousness of the cases.Although its case fatality risk has not been high,a significant percentage of patients require hospitalization.In this context,local initiatives were taken to extend the limited supply of vaccines against the disease;however,such measures have not been sufficient to contain the spread of cases and ensure an equitable distribution of health resources.As a result,endemic regions of low-income countries continue to have insufficient access to mpox vaccination.Despite this and considering the global scope of the disease,there is still little discussion in the literature about the difficulties in achieving adequate vaccination coverage rates for the target population of interest.In this article,we briefly discussed general aspects of the disease,including its surveillance,the current global context of challenges for mpox vaccination,and issues on global allocation of health resources as well as proposed related recommendations.
文摘This study aimed to examine the relationship between COVID-19 vaccine refusal and religiosity and fear of death among Muslims living in Turkey. This cross-sectional study was conducted online with 1046 adults aged 18 and older. The Ok-Religious Attitude Scale (Islam) (ORASI) (8 items) and Thorson-Powell Death Anxiety Scale (TPDAS) (20 items) were used as data collection instruments. The data were analyzed using the Pearson chi-square test, Student’s t-test, and binary logistic regression. A p-value of 0.05). In binary logistic regression analysis, vaccine rejection was 7.19 times higher among single people, 50.55 times higher among workers and tradesmen, and 3.36 times higher among people who did not have COVID-19. As religiosity increased, the risk of vaccine refusal decreased 1.037-fold.
文摘Background: Many countries across the world are facing an ongoing shortage of midwife practitioners due to several reasons such as increased workload, working overtime, poor-quality midwifery care, low staff morale, stress and burnout, lack of opportunity for training, lack of management support, financial issues and lack of recognition and compromised autonomy. Purpose: To explore the reasons behind nurses’ hesitance to apply for midwifery specialization. The objectives of this study were to understand the challenges that lie in front of Omani nurses and the motivational factors to apply for a midwifery programme. Method: Exploratory qualitative study was conducted at the largest tertiary hospital in Oman. Purposive sampling was applied for participant recruitment. Face-to-face interviews and focus group discussions were used as data collection methods. The study included general nurses, nurses in charge working in the maternity unit as well as nurses whose applications were accepted for midwifery education. Qualified midwives were excluded. The data collection process yielded twenty-five nurses. The interview protocol highlighted the impact and perception of the midwifery specialization on nurses’ careers. Thematic analysis was employed for data analysis. Results: Three over-arching major themes were identified. These are 1) nurses’ perceptions about the nature of work in maternity wards, the nurses have positive perception toward working in maternity wards and labor room because of working exclusively with female patients and their babies 2) factors influencing the decision to study midwifery specialization, work overload, stress, lack of support from administration were the most common reason behind the nurses not to apply for midwifery specialization and 3) support and recommendations required for midwives, the nurses mentioned that their identity, promotions and support from the administration will encourage them to apply for midwifery specialization. Conclusion: One of the main reasons that hindered nurses from applying to midwifery specialization is the false belief that midwives cannot work outside the delivery suite (DS). The second reason was the stress that midwives encounter at DS, and this was perceived by general nurses who did not work at DS. These challenges could be mitigated by leadership support, midwifery profession identity, as well as financial recognition for the midwives.

文摘Three-way decision(T-WD)theory is about thinking,problem solving,and computing in threes.Behavioral decision making(BDM)focuses on effective,cognitive,and social processes employed by humans for choosing the optimal object,of which prospect theory and regret theory are two widely used tools.The hesitant fuzzy set(HFS)captures a series of uncertainties when it is difficult to specify precise fuzzy membership grades.Guided by the principles of three-way decisions as thinking in threes and integrating these three topics together,this paper reviews and examines advances in three-way behavioral decision making(TW-BDM)with hesitant fuzzy information systems(HFIS)from the perspective of the past,present,and future.First,we provide a brief historical account of the three topics and present basic formulations.Second,we summarize the latest development trends and examine a number of basic issues,such as one-sidedness of reference points and subjective randomness for result values,and then report the results of a comparative analysis of existing methods.Finally,we point out key challenges and future research directions.

文摘In this paper,a stable two-sided matching(TSM)method considering the matching intention of agents under a hesitant fuzzy environment is proposed.The method uses a hesitant fuzzy element(HFE)as its basis.First,the HFE preference matrix is transformed into the normalized HFE preference matrix.On this basis,the distance and the projection of the normalized HFEs on positive and negative ideal solutions are calculated.Then,the normalized HFEs are transformed into agent satisfactions.Considering the stable matching constraints,a multiobjective programming model with the objective of maximizing the satisfactions of two-sided agents is constructed.Based on the agent satisfaction matrix,the matching intention matrix of two-sided agents is built.According to the agent satisfaction matrix and matching intention matrix,the comprehensive satisfaction matrix is set up.Furthermore,the multiobjective programming model based on satisfactions is transformed into a multiobjective programming model based on comprehensive satisfactions.Using the G-S algorithm,the multiobjective programming model based on comprehensive satisfactions is solved,and then the best TSM scheme is obtained.Finally,a terminal distribution example is used to verify the feasibility and effectiveness of the proposed method.

文摘The purpose of this study is to reduce the uncertainty in the calculation process on hesitant fuzzy sets(HFSs).The innovation of this study is to unify the cardinal numbers of hesitant fuzzy elements(HFEs)in a special way.Firstly,a probability density function is assigned for any given HFE.Thereafter,equal-probability transformation is introduced to transform HFEs with different cardinal numbers on the condition into the same probability density function.The characteristic of this transformation is that the higher the consistency of the membership degrees in HFEs,the higher the credibility of the mentioned membership degrees is,then,the bigger the probability density values for them are.According to this transformation technique,a set of novel distance measures on HFSs is provided.Finally,an illustrative example of intersection traffic control is introduced to show the usefulness of the given distance measures.The example also shows that this study is a good complement to operation theories on HFSs.
文摘In real life,incomplete information,inaccurate data,and the preferences of decision-makers during qualitative judgment would impact the process of decision-making.As a technical instrument that can successfully handle uncertain information,Fermatean fuzzy sets have recently been used to solve the multi-attribute decision-making(MADM)problems.This paper proposes a Fermatean hesitant fuzzy information aggregation method to address the problem of fusion where the membership,non-membership,and priority are considered simultaneously.Combining the Fermatean hesitant fuzzy sets with Heronian Mean operators,this paper proposes the Fermatean hesitant fuzzy Heronian mean(FHFHM)operator and the Fermatean hesitant fuzzyweighted Heronian mean(FHFWHM)operator.Then,considering the priority relationship between attributes is often easier to obtain than the weight of attributes,this paper defines a new Fermatean hesitant fuzzy prioritized Heronian mean operator(FHFPHM),and discusses its elegant properties such as idempotency,boundedness and monotonicity in detail.Later,for problems with unknown weights and the Fermatean hesitant fuzzy information,aMADM approach based on prioritized attributes is proposed,which can effectively depict the correlation between attributes and avoid the influence of subjective factors on the results.Finally,a numerical example of multi-sensor electronic surveillance is applied to verify the feasibility and validity of the method proposed in this paper.

文摘This research proposes multicriteria decision-making(MCDM)-based real-time Mesenchymal stem cells(MSC)transfusion framework.The testing phase of the methodology denotes the ability to stick to plastic surfaces,the upregulation and downregulation of certain surface protein markers,and lastly,the ability to differentiate into various cell types.First,two scenarios of an enhanced dataset based on a medical perspective were created in the development phase to produce varying levels of emergency.Second,for real-timemonitoring ofCOVID-19 patients with different emergency levels(i.e.,mild,moderate,severe,and critical),an automated triage algorithmbased on a formal medical guideline is proposed,taking into account the improvement and deterioration procedures fromone level to the next.For this strategy,Einstein aggregation information under the Pythagorean probabilistic hesitant fuzzy environment(PyPHFE)is developed.Einstein operations on PyPHFE such as Einstein sum,product,scalar multiplication,and their properties are investigated.Then,several Pythagorean probabilistic hesitant fuzzy Einstein aggregation operators,namely the Pythagorean probabilistic hesitant fuzzy weighted average(PyPHFWA)operator,Pythagorean probabilistic hesitant fuzzy Einstein weighted geometric(PyPHFEWG)operator,Pythagorean probabilistic hesitant fuzzy Einstein ordered weighted average(PyPHFEOWA)operator,Pythagorean probabilistic hesitant fuzzy Einstein ordered weighted geometric(PyPHFEOWG)operator,Pythagorean probabilistic hesitant fuzzy Einstein hybrid average(PyPHFEHA)operator and Pythagorean probabilistic hesitant fuzzy Einstein hybrid geometric(PyPHFEHG)operator are investigated.All the above-mentioned operators are helpful in design the algorithm to tackle uncertainty in decision making problems.In last,a numerical case study of decision making is presented to demonstrate the applicability and validity of the proposed technique.Besides,the comparison of the existing and the proposed technique is established to show the effectiveness and validity of the established technique.
