Precipitation deficit causes meteorological drought, and its continuation appears as other different types of droughts including hydrological, agricultural, economic, and social droughts. Multivariate Standardized Precipitation Index can show the drought status from the perspective of different drought types simultaneously. Forecasting multivariate droughts can provide good information about the future status of a region and will be applicable for the planners of different water divisions. In this study, the MLP model and its hybrid form with the Imperialistic Competitive Algorithm have been (...) investigated for the first time in multivariate drought studies. For this purpose, two semi-arid stations of western Iran were selected, and their precipitation data were provided from the Iranian Meteorological Organization, during the period of 1988–2017. MSPI was calculated in 5-time windows of the multivariate drought, including MSPI3–6, MSPI6–12, MSPI3–12, MSPI12–24, and MSPI24–48. The results showed acceptable performances in forecasting multivariate droughts. In both stations, the larger time windows had better predictions than the smaller ones. Generally, it can be reported that, by decreasing the size of the time window, the gradual changes of the index give way to sudden jumps. This causes weaker autocorrelation and consequently weaker predictions, e.g., forecasting droughts from the perspective of soil moisture and surface hydrology simultaneously. The hybrid MLP-ICA shows stronger prediction results than the simple MLP model in all comparisons. The ICA optimizer could averagely improve MLP’s accuracy by 28.5%, which is a significant improvement. According to the evaluations, the results are hopeful for simultaneous forecasting of different drought types and can be tested for other similar areas. (shrink)

Evapotranspiration represents the water requirement of plants during their growing season, and its accurate measurement at the farm is essential for agricultural water planners and managers. Field measurements of evapotranspiration have always been associated with many difficulties that have led researchers to seek a way to remotely measure this component in horticultural and agricultural areas. This study aims to investigate an indirect approach for daily rice crop evapotranspiration measurement by machine learning techniques and the least available climatic variables. For this (...) purpose, daily meteorological variables were obtained from three ground meteorological stations in rice cultivation regions of northern Iran during 2003–2016. The ETc rates were calculated by seven meteorological variables, the FAO-56 Penman-Monteith equation, and the regional calibrated rice crop coefficient and considered as the reference data. The MLs, including Multilayer Perceptron, Radial Basis Function, Generalized Regression Neural Network, and Group Method of Data Handling, were utilized for ETc modeling. Different input combinations were applied, based on the use of minimum effective variables as input. Results showed that the models showed the most accurate performances in the input combination of four climatic variables: sunshine duration, maximum temperature, relative humidity, and wind speed. Investigating the accuracy of models in rice growth phases showed that the least estimation error belonged to the initial growing stage, which increased during the mid-season and late-season growing stages. A comparison of the models showed that the GMDH model performed better against the other competitors. For this model, both the Nash-Sutcliffe coefficient and R2 were greater than 0.98, and the Root Mean Square Error ranged between 0.214 and 0.234 mm per day in all stations. The current approach showed promising results in rice evapotranspiration modeling by only four common meteorological variables and can be reliably applied for indirect measurement of this variable over the rice farms. The studied approach will have research value for rice and other crops in similar/different climatic conditions. (shrink)

With the shift toward online environments due to COVID-19 pandemic, particularly for educational sector, employees’ performance has been affected by an array of different factors. Personal aspects as well as organizational focus on individuals’ wellbeing are the main focus of this study through inclusion of job autonomy and work-life conflict alongside other factors, such as informational support that can aid academic staff regarding their wellbeing during times of crisis. In response to the effects of COVID-19 on employees, this study aims (...) to provide tangible data to protect university teachers during crises and establish key points that can improve their wellbeing. For this purpose, we used interviews to provide in-depth understanding of the subject. A total of 16 teachers as interviewees have provided qualitative data that was analyzed with MAXQDA. This study highlights the importance of work-life conflict and vitality of job autonomy on academic staffs’ performance and overall wellbeing through a conceptual analysis. We emphasize the role of organizations in maintaining a work environment where university teachers’ wellbeing is prioritized and various elements such as training and support are used to help stabilizing work-life balance. The current findings can be beneficial for both scholars and decision-makers in schools and universities to enhance elements of remote work for their staff. (shrink)

The U.S. oversight system for genetically engineered organisms was evaluated to develop hypotheses and derive lessons for oversight of other emerging technologies, such as nanotechnology. Evaluation was based upon quantitative expert elicitation, semi-standardized interviews, and historical literature analysis. Through an interdisciplinary policy analysis approach, blending legal, ethical, risk analysis, and policy sciences viewpoints, criteria were used to identify strengths and weaknesses of GEOs oversight and explore correlations among its attributes and outcomes. From the three sources of data, hypotheses and broader (...) conclusions for oversight were developed. Our analysis suggests several lessons for oversight of emerging technologies: the importance of reducing complexity and uncertainty in oversight for minimizing financial burdens on small product developers; consolidating multi-agency jurisdictions to avoid gaps and redundancies in safety reviews; consumer benefits for advancing acceptance of GEO products; rigorous and independent pre- and post-market assessment for environmental safety; early public input and transparency for ensuring public confidence; and the positive role of public input in system development, informed consent, capacity, compliance, incentives, and data requirements and stringency in promoting health and environmental safety outcomes, as well as the equitable distribution of health impacts. Our integrated approach is instructive for more comprehensive analyses of oversight systems, developing hypotheses for how features of oversight systems affect outcomes, and formulating policy options for oversight of future technological products, especially nanotechnology products.

U.S. approaches to oversight of research and technological products have developed over time in an effort to ensure safety to humans, animals, and the environment and to control use in a social context. In modern times, regulatory and oversight tools have evolved to include diverse approaches such as performance standards, tradable allowances, consultations between government and industry, and pre-market safety and efficacy reviews. The decision whether to impose an oversight system, the oversight elements, the level of oversight, the choice of (...) approach, and its execution can profoundly affect technological development, individual and collective interests, and public confidence in technological products. Oversight is conducted by a range of institutions with various capabilities, cultures, and motives. Avenues for disputing oversight decisions are also important, and some argue that the U.S. operates in an adversarial regulatory culture in which Congress, the media, and stakeholders regularly contest the decisions of federal agencies.

This work was presented at the Research Center for Philosophy of Science of the Ferdowsi University of Mashhad (Iran) – in Aug 2020. --- -/- Briefly, in the first section of this Persian book, first of all, I (Hereafter: the writer) have presented generalities of Aesthetics and an interpretation of aesthetic universality (Hereafter: φ) and it is argued that each definition of art has to admit φ and this is a Kantian, minimalist, and subjective perspective view (some others would incline (...) objective interpretation of φ, but it is beyond the purpose of this work). What’s more, this view could be applied to all definitions of art e.g. Functionalism, Conventionalism, or Hybrid Theories. Additionally, the writer has replied to some objections, those would promote definitions of art without φ, it seems that they could not be successful to refuse φ, since it appears that φ is a premise in every aesthetic judgment. Next, in another section, the writer has written some primary notes on creativity, those have come from contemporary literature of it, and it is argued that there is a relation between creativity and φ. It is also claimed that the relation is the same φ by the creative processes, creative products, and creative persons, both scientifically and philosophically; and so, the relation represents that φ is true. Besides that, the writer has presented some potential objections to the writer’s aspect of the relation and the writer has also replied to those objections. --- -/- In the next section of the book, the writer has applied the φ by creativity to the philosophy of animal-made art, the writer revolutionarily illustrates that first of all, the normativity of the philosophy of animal-made art is prior to the descriptive one. Second of all, φ is principally the criterion to know that animal-made art is impossible. The writer’s position recognizes those other works of animal aesthetics, which means aesthetics of all of the non-human creatures in the earth or cosmos as a new part of environmental aesthetics, is the marginally second order of animal aesthetics. It is owing to the fact that first of all, the question, of whether animal-made art is possible or not, is normative. Second of all, if one does not concern normativity of the question, then one could not get the answer to the nature of it. Next, one could not distinguish between on the one side, the pleasure of drinking water when one’s thirst may cause death, on the other side, the one’s pleasure of listening to music when there is no urgent necessity of it. The fourth argument is that one needs to identify the normativity of animal-made art because one could generalize aesthetic judgments if one sets φ as the basis of it, and then, one identifies that φ is one of the most fundamental bases in Aesthetics. --- -/- The main section of this book is that the writer’s argument -Animal-Made Art Impossibility Argument- is in favor of the impossibility of animal-made art i.e. Functionalist, Conventionalist, or Hybrid Theories of the definitions of animalmade art, also the writer has replied to some possible ideas and objections to the argument. --- -/- Pouya Lotfi Yazdi --- Iran | June 2022.

Surface acting is a heavy emotional and cognitive task practiced by nurses, which has negative consequences on their wellbeing. The shortage of nurses along with the occurrence of the COVID-19 pandemic has worsened the situation. Based on job demands-resources and conservation of resources theories, this study aims to investigate the adverse impact of practicing SA and buffering effect of a sense of community on job stress and cognitive weariness among Iranian nurses confronting COVID-19. As this study is written within the (...) scope of Frontiers’ call for research on “Spirituality in the workplace,” the findings suggest that the aforementioned factors are in significant positive relationships. Furthermore, the empirical evidence indicates that there is a significant indirect effect of SA on CW through JS. In addition, results reveal that there is a buffering effect of SOC on the SA and JS relationship, while there is no significant moderation effect regarding the JS and cognitive weariness association. The findings of this study provide theoretical and practical implications within the scope of spirituality in the workplace. (shrink)

Background Workplace Incivility is a common issue in the nursing profession. Nurses who are affected by such behaviors may experience distress. Objectives This study aimed to assess the relationship between workplace incivility and nurses’ professional quality of life. Research design This cross-sectional correlational study was conducted in 2021 in “Tehran”. Data were collected using a demographic questionnaire, the Nursing Incivility Scale (NIS), and the Professional Quality Of Life scale (ProQOL). Data analysis was performed through the Pearson correlation and multiple linear (...) regression, using the SPSS v.16. Participants and research context Participants were 200 nurses randomly recruited from selected hospitals of “TUMS”. Ethical considerations The study obtained research ethics approval and all participants were informed of the voluntary and anonymous nature of their participation. Findings The mean age of participants was 32.30 ± 7.22, and 76.5% were female. There was a significant correlation between the professional quality of life and workplace incivility ( r = −0.23, p =.001). Multiple regression analysis between the subscales of workplace incivility and professional quality of life demonstrated that the incivility from the supervisor ( β = −0.29, p =.001) and incivility from patients ( β = −0.27, p <.001) can predict the compassion satisfaction dimension. The incivility from the supervisor ( β = 0.24, p =.001) and incivility from patients ( β = 0.26, p <.001) can explain burnout. The incivility of the patients can explain secondary traumatic stress ( β = 0.14, p =.02). Conclusion This study showed that workplace incivility is significantly related to professional quality of life. Therefore, the reduction of behaviors of incivility can lead to the improvement of the professional quality of life. (shrink)

Individuals working in different industries were forced to change their work environments to their homes and quickly cope with technical and social changes not experienced before the occurrence of COVID-19 pandemic. This led to blurred boundaries between work and family roles, diminishing performance and wellbeing. Within the scope of the Research Topic “Workplace effects of COVID-19 on employees,” this research emphasizes on the positive impact of job autonomy provided by employers in reducing work-family conflicts. Moreover, the effect of work-family conflict (...) on employees’ performance and wellbeing is analyzed. Furthermore, informational support is examined regarding its moderating effect to mitigate work-family conflicts and enhance wellbeing. A survey was administered among employees of small-medium enterprises in Lebanon, through purposive and convenience sampling with 198 participants. The data was analyzed using PLS-SEM, and the results show that job autonomy reduces work-family conflict. This in turn improves performance and wellbeing as individuals have more control on their tasks. Furthermore, informational support provided to the employees serves as a buffer between work-family conflict and wellbeing. These results can be beneficial for managers of small and medium enterprises, seeking to enhance the performance and wellbeing of their employees in the era of the pandemic. Similarly, scholars can benefit from theoretical premises of current study and the potential pathways for future analyses. (shrink)
