This paper is aims to review the book entitled Review of History: What and Why? byBeverley Southgate. Our findings show that this book is not an original work which contains speculations of the author, but it is an elementary text book about one of the most important questions of the philosophy of history, i. e. Does history have any kind of objectivity? In a good manner, he gathered views of the former as well as the latter. Also, he shows that how the history, as a disciplines affected by other fields of humanities. Its language is simple and has a logical structure. But relativistic and subjectivist approach of the author is one of the challenging aspects of this book in Iranian philosophical atmosphere. This book is old and its subject matters are very limited.

Purpose – The purpose of this paper is to highlight the stressors involved in an occupation at potential risk – the profession of law enforcement. Design/methodology/approach – The paper reviews the history of police stress studies. It describes prevention and treatment programs that have unfortunately not been sufficiently utilized because of the police culture. Findings – The documented symptoms of stress include digestive orders, cardiovascular diseas, alcoholism, domestic violence, post-traumatic stress disorder, depression and suicide. While some police officers start their careers in excellent physical health, some retire early or even die from job-related stress disorders if the cumulative impact of stress exacts its toll. Originality/value – The paper offers a description of COP.2.COP a confidential hotline for officers and their families staffed by retired officers and licensed professionals.

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.

The under review book of Homo Deus, A Brief History of Tomorrow, is the second part of the trilogy of Sapiens, Homo Deus, and 21 Lessons for the 21st Century were all written by Yuval Noah Harari. In this book, the writer has first reviewed the history behind the formation of the human mindset from Paleolithic to the renaissance with particular emphasis on the scientific revolution and appearance of the humanism paradigm and its subdivisions (liberalism, socialism, and fascism). Doing so, he concluded that the invention of the internet of everything and using more sophisticated computer-generated algorithms by Google and Facebook (Dataism) would eventually put humans aside forever. The writers of this critique compared the Farsi translation with the English one and realized that some parts of the Farsi version suffer from improper translation, and some other parts have been deleted during the translation. In addition to that, it is probable that human societies might escape from the illustrated dark future by Harari. Learning from past events, and more importantly, using our global consciousness, which we possess more than ever, might change the inevitable future.

Background: The most frequently used test for evaluation of fetal health is the Non Stress Test (NST). Unfortunately it has a high incidence of false positive results. The combination of vibroacoustic stimulation with the NTS has been shown to reduce non reactive results.Methods: A tests assessment method was chosen with a simple randomized sampling. 40 pregnant women with non reactive NST in the first 20 minutes who received VAS in one of Tehran University's Hospitals were compared with BPP scores. A vibroacoustic stimulation was applied for a 3 seconds on the maternal abdomen and fallowed within 10 minutes. Data collection tools were NST, sonography instruments, NST result paper, tooth brusher, watch, demographic questioner and check list. Data analysis was made by descriptive static and by using the Fisher's Exact Test (with level of significant at p<0/05). All statistical analysis were performed using an spss/win.Results: After VAS, 70% of non reactive tracing became reactive. All cases with fetal reactivity response after a VAS had a subsequent BPP score of 8 (negative predictive value of 100%). False positivity of VAS was lower than NST.Conclusion: VAS offers benefits, by decreasing the incidence of non reactive test and reducing test time. VAS lowers the rate of false positive NST. VAS is safe and allows more efficient of prenatal services. This test could be used as a rapid antepartum test to predict fetal well-being.

Purpose: Application of heavy forces to maxillary dentition during treatment with headgear, induces high concentration of stresses in periodontal tissue. Quantification of this stress is of great concern in orthodontics. This study was designed to investigate the quantity and quality of stress response in the PDL of maxillary first molar which was subjected to high pull headgear traction using Finite Element method.Methods and Material: In an experimental study, a three-dimensional finite element model of maxillary dentition, consisting of 17096 elements and 23013 nodes, was developed based on a young human skull. The forces were applied to the maxillary first molar in the stabilized Arch by means of a rectangular full size arch wire in (022) slot bracket. Mechanical properties of this model were based on previous studies. A 350 gram force was used for high pull headgear to affect the dentition (+30 degree) and stress distribution was investigated in buccal, palatal, mesial and distal side and in cervical, middle, apical sections of the PDL. The quantity of stresses were expressed as principal stresses (1,2,3), while the negative and positive signs indicated compressive and tensile stresses.Results: The buccal surface of PDL of mesiobuccal root and the buccal, palatal and distal surface in cervical region of PDL of distobuccal root and the distal surface of the PDL of palatal root had received a great deal of stresses, in addition, the over all stress distribution in roots of molar had intrusive nature.Conclusion: The extension of high stress concentration areas observed after using high pull headgear is limited to some root surfaces specially the distobuccal root.

The purpose of this study was comparing the stress of breast cancer patients to that of healthy women. A sample of 65 breast cancer patients were selected from "Imam-Khomeini Cancer Institute" (from summer to autumn of 2008). They were chosen from the available patients who were diagnosed with cancer for less than two months. Variables such as marital status, economic status, age and education were taken into consideration in both the experimental and the control groups. Pickle's "life event" questionnaire (1971) was used to assess the stress in those groups. The data were analyzed using t-test. The results suggest that the stress in breast cancer patients is significantly higher than others. Moreover, women who bereaved the loss of a relative, had unwanted pregnancy or experienced divorce had more stress.
