This paper aims to propose a bi-level mixed integer linear location-allocation problem. The upper-level objective function is dedicated to minimizing the total distances covered by customers to meet the p-selected facilities and the fixed cost values for establishing these facilities. While in the lower level, a customer preference function evaluates the priority of customers in selecting facilities.

The solution approach to the proposed model uses the Karush–Kuhn–Tucker (KKT) optimality conditions to the lower-level problem where a set of p-selected facilities are introduced as the selection of the upper-level decision maker. The bi-level model reduces to a single-level model with some added binary variables.

Sensitivity analysis of the proposed bi-level model concerning variations of such different parameters as customers’ preferences and the number of selected facilities have been provided, using some numerical examples. Also, locating a recreational facility in Mazandaran province, Iran, has been provided to evaluate the reliability of the proposed model and efficiency of the solution approach, as well.

To the best of the authors’ knowledge, this paper is original and its findings are not available elsewhere.

Responsiveness is a reaction to the reasonable expectations of patients regarding ethical and non-clinical aspects of the health-care system. Responsiveness is a characteristic of health-care system and the observance of the patient’s rights. The purpose of this study is to compare the responsiveness of the health-care system based on the hospital ownership in Mazandaran province in Iran.

The cross-sectional study design was used on 1,083 patients referred to public and private hospitals and hospitals affiliated to social security organization in Mazandaran province in 2017. The World Health Organization’s responsibility questionnaire was used to collect data. Data were analyzed by using SPSS version 21. Descriptive statistics and one-way ANOVA results are presented is the results section.

All responsiveness dimensions were salient for respondents. The response rate in the selected hospitals was very close, which ranged from 85.7 to 90.2%, and there was no significant difference between public, private and social security hospitals (p > 0.05). The most crucial responsiveness dimension in hospitals was autonomy.

In the current study, the dimensions of communication and confidentiality were identified as priority dimensions based on the least score for breeding actions to improve the responsiveness of the health-care system. At the end, some useful recommendations such as re-engineering the processes, training to engage the employees with patients and encouraging them to fill the gap were suggested.

One of the largest floods in Iran happened in Nowruz in 2019, during which torrents of rain, flooding of rivers, landslides and the destruction of dams caused floods and led to financial losses and loss of life in 25 provinces of Iran. During and after the flood, 39 public libraries were closed, three libraries were evacuated and one was completely destroyed.

Despite the damage that occurred in the libraries, the preventive measures had been taken by many of them to reduce the whole damage. In addition, after the flood, responsible organizations including Iran Public Libraries Institution, the Institute for the Intellectual Development of Children and Young Adults and the Cultural and Art Organization of Municipality and the Mosques and Cultural Center, as well as other relief and social teams, and even people performed activities to reduce the negative impacts caused by the flood.

This article reviews these activities and their effectiveness. In the end, “the development of a plan for public libraries in natural and social crises” is proposed and the reasons for its necessity are discussed.

The current study is an attempt to investigate the residential satisfaction and prioritize effective components on residents' satisfaction based on household surveys conducted in eight Mehr housing complexes in Mazandaran province located in different counties of this region.

In the current work, using software of SmartPLS 3, second-order confirmatory factor analysis has been employed to evaluate and rank influential factors on residents' satisfaction.

As a result of descriptive analysis, 51.8% of the respondents were highly satisfied with Mehr housing complexes. Moreover, the results showed that there was the highest level of satisfaction (76.3%) with the security, while the lowest one (34.4%) was related to satisfaction with the facilities of the housing complexes. The standardized coefficients obtained showed that the components of physical characteristics (0.901), facility (0.863), neighborhood relationship (0.810), visual quality (0.774), security (0.737) and environmental health (0.715) have the most influence on the satisfaction of the residents, respectively.

This paper proved that migration has a significant effect on the level of residents' satisfaction, in multicultural cities. Therefore, it is crucial to promote social interaction and involvement among different ethnic groups in residential complexes that can result in intimacy, hence satisfying sociocultural needs, improving neighborhood relationships and consequent satisfaction of residents in Mehr housing projects in Iran.

The exploration of performance determinants in social enterprises has gained increasing relevance among researchers and practitioners, particularly in rural tourism. The purpose of this paper is to analyze the contributions of transformational leadership and social entrepreneurship to the performance of social enterprises in the context of rural tourism. Further, the mediating roles of social capital, creativity and social value were investigated.

Data were gathered through a survey of 168 employees of social enterprises operating in the rural tourism setting. Eight surveyors were sent out to conduct the survey. Data were analyzed by structural equation modeling (SEM) using AMOS 18.0.

The results of the SEM suggested that transformational leadership is positively associated with social value, social capital and performance of social enterprise. In addition, social entrepreneurship had a significant influence on social value, social capital and performance of social enterprise. Creativity and social value predicts the performance of social enterprise. Further, social capital was found to have a positive relationship with creativity. Finally, the mediating roles of social capital, creativity and social value were also confirmed. The findings thus highlight the power of the social value creation and social capital in the social enterprises operating in the rural destinations.

The findings assert that social entrepreneurship and transformational leadership are key sources of social value creation, social capital and creativity in rural tourism context indicating the need for additional efforts on this kind of entrepreneurial activity. The findings can motivate policymakers to promote social entrepreneurship in rural tourism destinations as a means of stimulating bottom-up social capital and social value creation.

This study is among the first to examine the hypothesized relationships focusing on tourism social enterprises.

OTA is primarily produced by species of Penicillium and Aspergillus. This toxin has been detected worldwide in different grains such as rice. Due to OTA's toxicity and its effects on human's health, the authors performed this study to analyze the OTA's contamination levels in rice samples that gathered in different cities of Mazandaran (a province in northern Iran). The paper aims to discuss these issues.

In this study, 80 rice samples were collected from several cities of Mazandaran. Data were analyzed using CD-ELISA method for OTA. Conjugated enzyme was added to uncoated-antibody wells and standard solution and sample extract were added to it. Solutions were transferred to the coated-antibody wells. Then, substrate was added to produce blue color. Finally, stopping solution was added to stop the reaction. The color intensity was inversely proportional to the OTA concentration, measured with the ELISA reader and calculated by analysis of variance by using the SPSS software package.

None of the samples that were collected in Mazandaran were contaminated with >5 μg/kg of OTA in October. Also none of the samples from Amol, Fereydonkenar, Babol or Behshahr were contaminated with >5 μg/kg of this toxin in November. But in sari, Nowshahr and Ramsar the authors encountered samples that had >5 μg/kg of OTA contamination which is more than the acceptable limit.

Screening and analyzing the rice fields are vital to detect any OTA contamination and can be effective for removing the contaminated rice. So proper strategies and management tactics are required in order to prevent OTA production in rice fields in pre- and post-harvest time and people must share their experiences regarding fighting this contamination.

Since rice is used extensively all over the world, consumption of contaminated rice causes diseases for humans. Therefore, determination, management, and prevention of OTA should be considered seriously.

This research aims to monitor vegetation indices to assess drought in paddy rice fields in Mazandaran, Iran, and propose the best index to predict rice yield.

A three-step methodology is applied. First, the paddy rice fields are mapped by using three satellite-based datasets, namely SRTM DEM, Landsat8 TOA and MYD11A2. Second, the maps of indices are extracted using MODIS. And finally, the trend of indices over rice-growing seasons is extracted and compared with the rice yield data.

Rice paddies maps and vegetation indices maps are provided. Vegetation Health Index (VHI) combining average Temperature Condition Index (TCI) and minimum Vegetation Condition Index (VCI), and also VHI combining TCI_min and VCI_min are found to be the most proper indices to predict rice yield.

The results serve as a guideline for policy-makers and practitioners in the agro-food industry to (1) support sustainable agriculture and food safety in terms of rice production; (2) help balance the supply and demand sides of the rice market and move towards SDG2; (3) use yield prediction in the rice supply chain management, pricing and trade flows management; and (4) assess drought risk in index-based insurances.

This study, as one of the first research assessing and mapping vegetation indices for rice paddies in northern Iran, particularly contributes to (1) extracting the map of paddy rice fields in Mazandaran Province by using satellite-based data on cloud-computing technology in the Google Earth Engine platform; (2) providing the map of VCI and TCI for the period 2010–2019 based on MODIS data and (3) specifying the best index to describe rice yield through proposing different calculation methods for VHI.

The regulation defines patients’ rights as a reflection of fundamental human rights in the field of medicine and incorporates all elements of patients’ rights accepted in international texts. Hence, the purpose of this paper is to investigate the relationship between patients’ safety, medical errors and patients’ safety rights with patients’ security feeling in selected hospitals of Mazandaran Province, Iran.

This descriptive cross-sectional study was conducted in selected hospitals of Mazandaran Province in public, social and private hospitals in 2016. In total, 1,083 patients were randomly selected for the study. The developed tool (questionnaire) was used for data collection. Questionnaire validity was verified through experts and its reliability was confirmed by Cronbach’s α coefficient (95 percent). Data were analyzed through multiple regressions by SPSS software (version 21).

The findings of this paper showed that the mean (standard deviation) medical error, patient’s safety, patient’s rights and patient’s security feeling were 2.50±0.61, 2.22±0.67, 2.11±0.68 and 2.73±0.63, respectively. Correlation testing results showed that medical error, patient’s safety and patient’s rights simultaneously had a significant relation with patient’s security feeling in the selected hospitals (p<0.05).

A simultaneous correlation between patient’s safety, patient’s rights and medical errors with patient’s security feeling in social security hospitals was higher than other hospitals. Hence, the authorities and officials of hospitals and healthcare centers were advised to make effective attempts to perceive the patient’s safety, medical errors and patient’s rights to improve the patient’s security feeling and calmness and also to make better decisions to promote the healthcare and therapeutic services.

Respect for human rights is one of the most important criteria for the delivery of medical care in hospitals. Ethical predictability is useful to identify human rights concerns in health-care organizations. The hospital environment and the flow of its processes make the topic of predictability much more sensitive and, at the same time, more difficult than other organizations. The purpose of this paper is to determine and compare the ethical predictive factors in selected hospitals in Mazandaran province.

This cross-sectional survey using multilevel sampling (four hospitals, 938 patients, 186 staff) was conducted in the first half of 2017. The measurement instrument was a researcher-made questionnaire consisting of seven areas of service recipients’ rights, patient safety, patient satisfaction, human resources, governance, organizational and financial commitments. The analysis of the collected data was performed through SPSS V. 22 and one-way ANOVA and post hoc Tukey’s tests.

Ethical predictability was higher in social security hospitals compared to private and public hospitals, and patient safety and patient rights showed higher magnitudes compared to other dimensions. Financial domain, patient satisfaction, governance and organizational commitment formed the middle priorities in ethical predictability, and human resources had the least average in ethical predictability in the selected hospitals in the province.

Identifying the factors which influence ethical predictability, in addition to promoting service recipients’ rights and patient satisfaction, is of great help to the managers and health service authorities, so that they can have a better understanding of these factors and, consequently, make appropriate micro and macro-decisions to provide better services.

Accessing adequate healthcare to all people is one of the main goals of the health sector. The purpose of this paper is to investigate healthcare services access development of the provinces in Iran during 2007 and 2013.

This is a descriptive cross-sectional study. The study population included all the provinces in Iran. The data for 13 variables, including physical and human health resources, was collected from the Ministry of Health and Medical Education and the Statistics Center of Iran. Taxonomy technique was used to determine the degree of healthcare services access development in the provinces.

The findings show that Semnan was the province with the most developed healthcare services access with development score of 0.342 while Sistan Balocehstan province was the least developed with development score of one in 2007. In the year 2013, Chahar-Mahal Bakhtiari and Sistan Baluchestan were the least and most developed provinces with scores of 0.551 and 0.989, respectively. The mean and standard deviation of the development scores in access to healthcare services in 2007 and 2013 were 0.7463±0.1268 and 0.7766±0.1058, respectively.

Most previous studies that examined disparities in access to healthcare resources in Iran only considered one resource. This study applied a taxonomy technique to investigate the disparity and changes in access using 13 main healthcare resources. This approach helped the authors to investigate whether the decisions of the policy makers were intended to eliminate the disparities.
