One of the factors that can be the link between our intentions and actions and their external consequences is human agency, which indicates the conscious design and intentional execution of actions by the individual in order to influence future events.Objective and Method: This research with a developmental approach of psychometric method and method 1, examines the psychometric indices of the Human Factor Characteristics Scale using the classical THEORY of test score measurement and the graduated question-answer THEORY. The purpose of this study, which included high school students in Tehran, was selected by cluster sampling of 500 people as a sample size and statistical analysis was performed on 481 data. To collect the data, the ion Human Agent Characteristics Scale (2011) was used and the research questions were evaluated using IRTPRO and SPSS software.Results:The assumption of local independence based on Pearson x2 index was established by applying Simjima's calibrated question-answer THEORY and the assumption of being one-dimensional based on the analysis of multidimensional question-answer THEORY. Diagnosis parameters with question-answer approach and classical approach Test score Both item 25 approach had the lowest and item 2 had the highest diagnosis parameter. The answer thresholds for all the questions were so far apart that no option was covered by the other option, and the options were independently selected by individuals at intervals of theta. The total scale was calculated with Cronbach's alpha of 0.945, intentionality of 0.894, foresight of 0.780, self-reactivity of 0.871 and rethinking of 0.762. Also, the role of each item in internal consistency was investigated by the loop method, which all questions had a favorable role in internal consistency of this scale. The value of the validity coefficient obtained from the question-answer THEORY was obtained by marginal method for intentionality 0.92, forethought 0.85, self-reaction 0.91, rethinking 0.83..

Introduction: Poisson ratio and modulus of elasticity are two fundamental properties of elastic and viscoelastic solids that use in solving all contact problems, including the calculation of stress, the contact surfaces and elastic deformation (Mohsenin, 1986; Gentle and Halsall, 1982)....

In this study, to determine poisson’s ratio and modulus of elasticity of white seedless grapes during maturation, the fresh fruit samples were harvested from a vineyard at seven sequential weeks from 6th September to 18th October. In each run, six grape berries were randomly selected and the static loading test and digital photography were done together. Considering true shape of the fruit and an allowable deformation value, and also using HERTZ’S THEORY with a true poisson’s ratio (experimental), modulus of elasticity was calculated. Apparent poisson’s ratio was determined by the image processing, too, and then obtained values of poisson’s ratio were modified using finite element software (ABACUS). Results showed that measured modulus elasticity by the HERTZ’S THEORY depends on the magnitude of axial strain and increases with increasing that. Regarding the results, the calculated poissoon’s ratios are less than that true one, depending on the axial strain value. It was found that both modulus of elasticity and poisson’s ratio decreased during maturation.

This article introduces, analyzes, and criticizes the work of Lawrence M. Hinman, Ethics: A Pluralistic Approach to Moral THEORY. Hinman is a Philosopher of Ethics in the multimedia learning. He believes that multiculturalism is important factor of nowadays so the most important responsibility of philosophers of Ethics is prevention of moral conflict. The global communication and information in 21st century needs global tolerance and respect of various nations, cultures, and moralities together because different people and societies have a common human nature and common natural rights that obligate to justice and moral relationship between different people and various societies’ beliefs throughout the world. Moral communication in multiculturalism approach is against racial, gender, national, and ethnic prejudice. Hinman believes in moral dialogue and global learning across different cultures. The book of Ethics: A Pluralistic Approach to Moral THEORY has a proper category of new ethical problems, and the candid standpoint of author is considerable. He has a logical method, and in the end of every part of book there are some questions for evaluation of students learning. So this book is proper for the philosophy of ethics in universities.

This paper examines the work of Immanuel Kant in the light of a new THEORY on the nature of truth, knowledge and falsehood (the Inversion THEORY of Truth). Kant’s idea that knowledge could be absolutely certain, and that its truth must correspond with reality, is discredited by a dissection of the Correspondence THEORY of Truth. This examination of the nature of truth, as well as knowledge and falsehood, is conducted with reference to Sir Karl Popper’s writings on regulative ideas, the criterion of demarcation and the principle of falsifiability. It is argued that if truth is to be regarded as certain, it should be used to describe objects and events in the objective (noumenal) state, and that subjective knowledge must contain (and is improved by) falsehood. Perceptions and knowledge are obtained by the biological and evolutionary process of Active Subjectivism. Ideas we have knowledge of can be metaphysical or scientific, according to Popper’s Criterion of Demarcation. Kant’s “Copernican revolution” claim that our intellect imposes absolutely true laws on nature could not allow for the possibility that ideas might be constructed from fallible perceptions, and hence that all knowledge is uncertain. Instead, he developed a Critique of Practical Reason in which religion, though not provable through logical reasoning, could be proved by our innate moral sense, giving us a Categorical Imperative that could lead to perverse results. By rejecting the absolute certainty of a priori knowledge, and admitting a degree of essential falsehood, we arrive at a more reasonable grounding for moral behavior.

Different narratives have been offered so far of the nature of science and scientific activity. Roy Bhaskar as one of the leading critical realists seeks to set the ground for a Copernican Revolution in the philosophy of science which seems to have been handled well by him. To this end, he proceeds to highlight the ontological debates and at the same time pays attention to the social nature of science. In “, A Realist THEORY of Science”, , which contains original and powerful arguments in the philosophy of science, not only does he raise criticisms against some philosophical schools and explains his own THEORY of science, rather he does also broach significant categories in the philosophy of science. His remarks with their philosophical basis can inspire the scholar who studies Bhaskar’, s philosophy. Among the most important ones of these categories, one can refer to the mutuality of ontological realism and epistemological relativism as well as his criticism of Tarsky’, s THEORY of truth. This essay aims at reviewing Bhaskar’, s key work in the philosophy of natural sciences and identification of its points of weakness and strength using a descriptive-analytic method. This is undertaken through a detailed review of the whole book in view of its formal, qualitative, and content dimensions. The essay is concluded by a number of practical suggestions.

The book “, History and THEORY in Anthropology”,by Alan Barnard, a leading researcher and author of anthropological studies, especially anthropology in South Africa is among valuable works in the field of anthropology. In this book, he examines the theoretical nature of anthropology throughout history and the views of prominent scholars and thinkers of this science and their comparisons, as well as the rooting of theories and schools of thought presented in the field of anthropology. The purpose of this book is to examine the pioneering views of anthropological studies, evolution in all its dimensions, the THEORY of disseminators in cultural areas, functionalism and structural functionalism, pragmatic theories, processing, and Marxist views, various aspects of relativism, structuralism and post-structuralism, postmodernist views and recent interpretations. Although this work should be regarded as an overview of anthropological theories and related problems since it lacks the details of theorists, approaches, and ideas, its very briefness of the terms and contents, its conceptual clarity and explanation have been diminished and it requires revisions.
