    peer reviewedConsidering the increasing importance of sustainable operations in the agricultural sector and the relationship between producers and consumers, the current study was to determine customers' attitudes on participation in community-supported aquaculture programs in Kurdistan province (in the west of Iran). The present study was a survey, non-experimental, applied, and descriptive-correlational research. Using a literature review and field studies, factors affecting consumers' attitudes have been extracted. Then, to determine validity, the questionnaire was given to a panel of subject matter experts. Furthermore, to assess the reliability of the research instrument, the Cronbach's alpha coefficient was calculated. The results showed the good validity and reliability of the research tool. Moreover, structural equation modeling was used to confirm the proposed model. The results showed that among the factors affecting the attitude of consumers, the price of aquatic products had the first place, which has been neglected in the previous studies. In this regard, it was suggested that by creating support funds and facilities for the participation of consumers in community-supported aquaculture programs, setting standards for healthy aquatic products, and producing programs related to the introduction of community-supported aquaculture programs on the radio and television, the attitude of the consumers can be improved

    Purpose: The success of vasectomy is determined by the outcome of a post-vasectomy semen analysis (PVSA). This article describes a step-by-step procedure to perform PVSA accurately, report data from patients who underwent post vasectomy semen analysis between 2015 and 2021 experience, along with results from an international online survey on clinical practice. Materials and Methods: We present a detailed step-by-step protocol for performing and interpretating PVSA testing, along with recommendations for proficiency testing, competency assessment for performing PVSA, and clinical and laboratory scenarios. Moreover, we conducted an analysis of 1,114 PVSA performed at the Cleveland Clinic’s Andrology Laboratory and an online survey to understand clinician responses to the PVSA results in various countries. Results: Results from our clinical experience showed that 92.1% of patients passed PVSA, with 7.9% being further tested. A total of 78 experts from 19 countries participated in the survey, and the majority reported to use time from vasectomy rather than the number of ejaculations as criterion to request PVSA. A high percentage of responders reported permitting unprotected intercourse only if PVSA samples show azoospermia while, in the presence of few non-motile sperm, the majority of responders suggested using alternative contraception, followed by another PVSA. In the presence of motile sperm, the majority of participants asked for further PVSA testing. Repeat vasectomy was mainly recommended if motile sperm were observed after multiple PVSA’s. A large percentage reported to recommend a second PVSA due to the possibility of legal actions. Conclusions: Our results highlighted varying clinical practices around the globe, with controversy over the significance of non-motile sperm in the PVSA sample. Our data suggest that less stringent AUA guidelines would help improve test compliance. A large longitudinal multi-center study would clarify various doubts related to timing and interpretation of PVSA and would also help us to understand, and perhaps predict, recanalization and the potential for future failure of a vasectomy.American Center for Reproductive Medicin

    The purpose of the present study was to analyze the effective components of educational transformation in agricultural higher education system in Iran by a mixed study method. The statistical population includes all faculty members (N=361) teaching in agricultural college of Tehran, Tarbiat Modares and Shiraz University, and a sample of 186 faculty members (n=186) were selected by stratified random sampling method and finally 166 questionnaires were returned and analyzed. Data collection in this research was done in two general sections. Section one was a meta-synthesis method. In this method, effective components of educational transformation were identified according to investigation objectives, method of sampling, methodology, content analysis, and research results of 25 selected studies. The results of this analysis identified five main factors influencing educational transformation. These components included learning, education and teaching, competence, quality of education, and leadership. Section two was done in order to examine the hypotheses by using Structural Equation Modeling (SEM). The Results of this section showed that new learning models, leadership styles and educational competence had significant effects on educational transformation

    A Performance-based Approach to Automatic Redeployment of Enterprise Software Applications

    Update of software usually equates disruption to a program’s execution. However, such disruptions in the execution of applications that provide round-the-clock services is not desirable. Examples of such applications include multi-tier enterprise systems with which users may interact via distinct presentation tiers at the same time. Existing software updating systems do not operate in the enterprise applications, or they need most of the redeployment tasks to be performed manually. In this paper, we present a framework capable of Automatically Redeploying Enterprise Software Applications (ARESA). This system combines the idea of incremental and integral updates to preserve the consistency of applications and to minimize disruption times during redeployments at the same time. It also utilizes the update bringing forward techniques in order to enhance the system’s predictability. ARESA has been used in updating a desktop costing application, a custom web program, and Joomla content management system. The experimental results show that in applications with real-life complexities, ‘speed’ and ‘size’ overheads incurred by ARESA are less than 19% and 1%, respectively

    This study provides a framework and definition to the notion of talent management process and describes how it fits the human resources architecture of agricultural higher education system in Iran. This qualitative study was conducted using semi-structured interviews for data collection and systematic grounded theory methods for data analysis. For this study, we selected and interviewed 15 experts of agricultural extension and education and human resources management by snowball sampling. Furthermore, we transcribed and analyzed the interviews and literature using the MAXQDA software. Using the systematic Grounded Theory Method, our findings suggest that equal treatment with talents and other staff was the main concern of the experts. Based on the results, organizational factors and human factors were involved to resolve this concern. In addition, with regard to the contextual and individual factors, the talent management process can play an important role in improving workforce and the organizational performance in agricultural higher education system

    Different countries face diverse challenges for Conservation Agriculture (CA) development. The main purpose of this study was to examine the challenges of applying CA in Iran from the perspective of experts and farmers. A focus group method was used to investigate the challenges. The research sample consisting of farmers and experts of CA in different provinces includes those 19 experts and 15 farmers. Inductive content analysis and coding (open, axial, and selective coding) were employed to analyze the farmers’ and experts’ discussions. The findings showed that the challenges of applying CA in the studied provinces could be divided into 6 general categories: institutional-infrastructure (7 concepts), economic (5 concepts), training-research (2 concepts), environmental (4 concepts), mechanization (2 concepts), and cognitive (2 concepts) challenges. The economic and institutional-infrastructure challenges were the most frequent related to applying CA. It can be concluded that to solve the challenges of applying CA, it is necessary to link various sectors of government (the Ministry of Agriculture), education and research (Agricultural Research, Education and Extension Organization), and industry together. But farmers themselves are also a major contributor to meet the challenges of CA development through participation in planning CA project and training-extension programs. Therefore, farmers’ communities should also pave the way for a transition from conventional agriculture to CA with their participation
