Suicide from the Perspective of Islam and Psychology with an Emphasize on the Models Explaining the Relationship between Impulsivity and Suicidal Behaviors

Suicide is the act of taking one's own life which is made within the framework of a voluntarily action by an informed individual. Impulsivity is one of the most reasons for the emergence of suicidal behaviors. Impulsivity takes place without considering the possible consequences of the action and for a fast access to a reward.The purpose of the present study is to study suicide in the perspective of Islam and psychology with an emphasize on the models explaining the relationship between impulsivity, suicidal behaviors and to discuss each model as well. Due to the multilayer nature of suicide, the research methodology is in documentation-based, analytical and meta-analytical forms.In order to study the models explaining the relationship between impulsivity and suicidal behaviors, different data bases and with key words such as: impulsivity, impulsive behaviors, suicidal behaviors and as likes were broadly reviewed and upon completion of data collection, the related studies were closely examined.The research findings indicate that in the perspective of Islam, suicide is in connection with components such as: the weakness of ideological and ethical bases, the lack of positive perception and disappointment with God, the lack of thinking on the belongings, magnifying the hardships and shortages, and considering the life as something meaningless. In psychology, based on the personality model, the impulsive individuals have a greater inclination towards experiencing the provocative and painful incidents. From the viewpoint of idea to practice framework, the forecasting factors of suicide are classified based on the rate of risk of suicidal ideations and also the rate of action risk for suicide.  In the integrated conceptual model, the evaluation of the suicide risk is made integrally and during the treatment process. The model of addiction to suicide, considers the suicidal behaviors as a kind of addiction. The three-step theory states that in the event that the sense of pain is associated with disappointment, and the lack of dependence on life and companions, the individual will make suicidal behaviors. The result is that in the perspective of Islam, the growth of awareness and increase of intellectual skills aiming at gaining knowledge and improving the relationship between human and God, reinforcing the basic beliefs and monotheistic doctrine are the most basic and effective steps to deter the suicidal behaviors. In psychology, opposite to the prevailing beliefs, it seems that impulsivity is not considered as a trustable forecaster for suicidal actions and the personality feature of impulsivity does not have a strong and noticeable relationship with suicidal actions

Image quality metric based on mutual information of image features

Objective image quality assessment has always been a challenging issue among image processing scientists. Here, a novel image quality metric based on mutual information of image features is presented. The proposed metric calculates the amount of information that one image contains about the other. Normalized feature vectors extracted from the test and reference images represent the considered information as the marginal probability distributions. In order to use the mutual information we need not only the marginal probability distributions but also the joint distribution between two images. In this work, Nelsen's method is employed to estimate the joint probability distribution from marginal distributions using the correlation between two feature vectors. Experimental results and comparisons with other well-known full-reference metrics like SSIM, MSSIM, FSIM and SFF certify the soundness of our proposed metric

Evaluation of the optical flow methods on facial expression classification

Facial expression recognition is an important issue in modern human computer interaction (HCI). In this work, the performance of optical flow in tracking facial characteristic points (FCPs) is examined and it is used as an application for facial expression classification. FCPs are extracted using active appearance model (AAM), and the features selected to the classification are the perceived movements of the FCPs and the changes in the geometric distance between them. This work compares four different optical flow methods on FCP tracking: normalized cross-correlation, Lucas-Kanade, Brox, and Liu-Freeman. Nearest neighborhood rule is used for the classification. Evaluations are done on the Cohn-Kanade (CK+) database for five prototypic expressions. Experimental results show that Lucas- Kanade method outperforms the other three optical flow methods. This has been assessed based on ground truth established in CK+ database

Structural Model of Explaining Social Problem Solving Skills in Teachers Based on Organizational Culture and Religious Orientation: The Mediating Role of Intellectual Property

The aim of this study was to provide a structural model for explaining social problem solving skill in teachers based on organizational culture and religious orientation with the mediating role of intellectual property. The research method was of correlation type. The statistical population of the study was the teachers employed in the academic year 2017-2018 in two regions 1 and 6 of Tehran province. The statistical sample included 250 male and female teachers who were selected by the cluster random sampling method. For data collection, 4 questionnaires of social problem solving skill (De Zorilla et al., 2002), religious orientation (Bahrami, 2001), intellectual property questionnaire (Bonitz (1998), and organizational culture questionnaire with the Islamic approach of Attaran et al. (2017) were used. Data were collected using structural equation modeling (SEM) and analyzed at two levels of descriptive statistics and inferential level using AMOS and SPSS-22 software. The results showed that effective religious orientation predicts the adaptive skills of social problem solving in a positive and meaningful way and also intellectual property predicts adaptive skills of social problem solving in a positive and meaningful way in teachers. On the other hand, the findings indicated that intellectual property mediates the relationship between organizational culture and adaptive problem solving skills in a positive and meaningful way. But intellectual property does not significantly mediate the relationship between effective religious orientation and maladaptive social problem-solving skills. According to the research results, adaptive social problem solving skills of teachers are predicted based on organizational culture and religious orientation mediated by intellectual property

Design and implementation of a low-cost mechatronic shoe for biomechanical analysis of the human locomotion

In this paper the development of a low-cost and easy wearable mechatronic system for the measurement of ground reaction forces (GRF) for the biomechanical analysis of the human locomotion is presented. The system consists of an insole, a conditioning device for the signals produced by the sensors applied to the insole and a data acquisition system connected to a USB portable storage. The sensors applied to the insole can measure the reaction forces in the horizontal and vertical directions during locomotion. The prototype was validated by comparing the data from the sensors with the values obtained using a force platform

Adapting to climate risks and extreme weather: a guide for mining and minerals industry professionals

Abstract Extreme weather events in Australia over recent years have highlighted the costs for Australian mining and mineral processing operations of being under-prepared for adapting to climate risk. For example, the 2010/2011 Queensland floods closed or restricted production of about forty out of Queenslands fifty coal mines costing more than $2 billion in lost production. Whilst mining and mineral professionals have experience with risk management and managing workplace health and safety, changes to patterns of extreme weather events and future climate impacts are unpredictable. Responding to these challenges requires planning and preparation for events that many people have never experienced before. With increasing investor and public concern for the impact of such events, this guide is aimed at assisting a wide range of mining and mineral industry professionals to incorporate planning and management of extreme weather events and impacts from climate change into pre-development, development and construction, mining and processing operations and post-mining phases. The guide should be read in conjunction with the research final report which describes the research process for developing the guide and reflects on challenges and lessons for adaptation research from the project. The Institute for Sustainable Futures, University of Technology Sydney (UTS) led the development of the guide with input from the Centre for Mined Land Rehabilitation, University of Queensland and a Steering Committee from the Australasian Institute of Mining and Metallurgys Sustainability Committee and individual AusIMM members, who volunteered their time and experience. As the situation of every mining and mineral production operation is going to be different, this guide has been designed to provide general information about the nature of extreme weather events, and some specific examples of how unexpectedly severe flooding, storm, drought, high temperature and bushfire events have affected mining and mineral processing operations. A number of case studies used throughout the guide also illustrate the ways forward thinking operations have tackled dramatically changing climatic conditions. Each section of the guide outlines a range of direct and indirect impacts from a different type of extreme weather, and provides a starting point for identifying potential risks and adaptation options that can be applied in different situations. The impacts and adaptation sections provide guidance on putting the key steps into practice by detailing specific case examples of leading practice and how a risk management approach can be linked to adaptive planning. More information about specific aspects of extreme weather, planning and preparation for the risks presented by these events, and tools for undertaking climate related adaptation is provided in the `Additional Resources section

Rapid prototyping of microfluidic devices for culture of suspended cell sheets

Embryogenesis is not only interesting as a research base perspective but also from applied tissue engineering point of view because this is how tissues are created naturally. In only a few days, a mammalian fertilized egg undergoes cell divisions and subsequent reorganization to progress through morula and then blastocyst. Some cells of the inner cell mass give rise to a surface layer known as primitive endoderm, and the others epithelialize to form the epiblast layer. This epiblast cell layer, pluripotent tissue, then undergoes gastrulation to develop all tissues and organs of the embryo. As these stages of development are not accessible in many organisms due to ethical and practical challenges, the bulk of our understanding is derived from mice. Therefore, an in vitro model is needed to replicate in vivo structure and microenvironment and study pre-implantation mammalian development in a physiologically relevant form. Overall, we could rapidly prototype a microfluidic platform in an easy, fast and low-cost manner that allows us to control concentration gradients of relevant signals over selected positions of suspended cell sheet, where there is a need. As we aimed to make microfluidic fabrication more accessible to biology labs with no expertise in microfluidic field, this work also led to an easy-to-use kit to make microfluidics available to non-experts. We could also successfully teach this technique to graduate students, professionals at the university level, and younger students (grade 6-8) at summer camp. Cell sheet formation was successful to some extent using an artificial extracellular matrix, StemAdhere, however, these suspended cell sheets could not resist the compression caused by clamping the device

Design, Development and Characteristics of an In-Shoe Triaxial Pressure Measurement Transducer Utilizing a Single Element of Piezoelectric Copolymer Film

In gait analysis, there is growing awareness of the need to simultaneously measure shear and vertical forces for the diagnosis and treatment assessment of pathological foot disorders. This is especially the case in the measurement of the forces between the plantar surface of the foot and the shoe. Although clinical awareness of the need to simultaneously measure shear and vertical forces under the foot has increased little has been done to provide the technology. This is mainly due to the difficulty in constructing devices capable of carrying out this task in the in-shoe environment. The aim of this paper is to describe the development and characteristics of a miniature triaxial transducer measuring 10 10 2.7 mm and a weight of only 2 g. This transducer is capable of simultaneously measuring three orthogonal forces under any location of the plantar surface of the foot utilizing a single element piezoelectric copolymer P(VDF-TrFE). Transducer sensitivity, linearity, hysteresis, cross-talk and temperature dependence is presented. As well as in-shoe force measurement, this triaxial transducer could have other biomedical and general engineering applications, e.g., prosthetic interface forces, handgrip forces, sport, robotics, etc
