No full textDistribution of killer cell immunoglobulin-like receptors (KIR) and their HLA-C ligands in two Iranian populations
No full textKiller cell immunoglobulin-like receptors (KIR) gene frequencies vary between populations and contribute to functional variation in immune responses to viruses, autoimmunity and reproductive success. This study describes the frequency distribution of 12 variable KIR genes and their HLA-C ligands in two Iranian populations who have lived for many generations in different environments: the Azerbaijanis at high altitude and the Jonobi people at sea level. The results are compared with those published for other human populations and a large group of English Caucasians. Differences were seen in KIR and HLA-C group frequencies, in linkage disequilibrium and inhibitory/activating KIR ratios between the groups. Similarities with geographically close populations in the frequencies of the KIR A and B haplotypes and KIR AA genotype reflected their common ancestry. The extreme variability of the KIR gene family and their HLA-C ligands is highlighted and their importance in defining differences between geographically and culturally isolated communities subject to different environmental pressures who come from the same ethnic grouping

Open Access to Peer-Reviewed Research through Author/Institution Self-Archiving: Maximizing Research Impact by Maximizing Online Access
No full textAll refereed journals will soon be available online; most of them already are. This means that anyone will be able to access them from any networked desk-top. The literature will all be interconnected by citation, author, and keyword/subject links, allowing for unheard-of power and ease of access and navigability. Successive drafts of pre-refereeing preprints will be linked to the official refereed draft, as well as to any subsequent corrections, revisions, updates, comments, responses, and underlying empirical databases, all enhancing the self-correctiveness, interactivity and productivity of scholarly and scientific research and communication in remarkable new ways. New scientometric indicators of digital impact are also emerging <http://opcit.eprints.org> to chart the online course of knowledge. But there is still one last frontier to cross before science reaches the optimal and the inevitable: Just as there is no longer any need for research or researchers to be constrained by the access-blocking restrictions of paper distribution, there is no longer any need to be constrained by the impact-blocking financial fire-walls of Subscription/Site-License/Pay-Per-View (S/L/P) tolls for this give-away literature. Its author/researchers have always donated their research reports for free (and its referee/researchers have refereed for free), with the sole goal of maximizing their impact on subsequent research (by accessing the eyes and minds of fellow-researchers, present and future) and hence on society. Generic (OAi-compliant) software is now available free so that institutions can immediately create Eprint Archives in which their authors can self-archive all their refereed papers for free for all forever <http://www.eprints.org/>. These interoperable Open Archives <http://www.openarchives.org> will then be harvested into global, jointly searchable "virtual archives" (e.g., <http://arc.cs.odu.edu/>). "Scholarly Skywriting" in this PostGutenberg Galaxy will be dramatically (and measurably) more interactive and productive, spawning its own new digital metrics of productivity and impact, allowing for an online "embryology of knowledge.
پیشبینی وسواس و فوبیا در دانشجویان دانشگاه علوم پزشکی تهران: نقش مفهوم خدا
No full textخلفية البحث وأهدافه: إن مفهوم الله، الذي ينتقل عن طريق الثقافة اللغوية والكلامية الى البشر، ويحدد الإدراك البشري لله، يرتبط ارتباطا وثيقا بالسلامة النفسية للأفراد. فالغرض من الدراسة هذه، التنبؤ بالوسواس القهري والرهاب على اساس مفهوم الله لدى طلاب جامعة.
منهجية البحث: هذا البحث من النوع الوصفي. الارتباطي ويشتمل المجتمع الاحصائي، جميع طلاب جامعة طهران للعلوم الطبية حيث تم اختيار 367 منهم باستخدام طريقة أخذ العينات الحصصية وتم تنفيذ (تطبیق) مقياس المفهوم الفردي لله (GCS) ومقاييس الوسواس القهري والرهاب في قائمة أعراض المرض (R90SCL-) عليهم. تمت مراعاة جميع الموارد الاخلاقية في هذا البحث؛ و اضافة الى هذا فإن مؤلفي المقالةلم يشيروا الى تضارب المصالح.
الكشوفات: كشف تحليل البيانات باستخدام تحليل الانحدار المتعدد أنه يمكن توقع الوسواس القهري والرهاب من خلال مفهوم الله عند الطلاب. كما أظهرت نتائج الدراسة أن الطلاب الذكور الذين لديهم مفهوم إيجابي عن الله لديهم نسبة اقل من الرهاب (05/0P< و 24=r)، والطالبات اللواتي كانت لهن نظرة ايجابية عن مفهوم الله كانت نسبة الوسواس القهري عندهن أقل من غيرهن (05/0P< و 28=r).
الاستنتاج: يمكن الاستنتاج من الكشوفات أن كلا من الوسواس القهري والرهاب عند الطلاب في الواقع يعتمدان على نوعية مفهوم الله ومستوى وجوده لدى الطلاب.

DOI: https://doi.org/10.22037/jrrh.v4i4.12673Background and Objective: The concept of God which is conveyed to individuals by means of oral and cultural media is a conceptual understanding of people about attributes of God and is closely associated with psychological health of individuals. Having said that, the aim of the current research was predicting obsessive-compulsive behavior and phobic anxiety in students of Medical Sciences in 2014, examining the role of the concept of God in this regard.
Method: In this descriptive-correlational study, whose statistical population was the students at Tehran University of Medical Sciences, 367 students were selected by proportional stratified sampling. God Concept Scale and Scales of Obsessive-Compulsive and Phobic Anxiety of Symptoms Checklist-90R were administered on them. All ethical issues were observed in this study and the researchers declared no conflict of interests.
Results: Multiple regression analysis of the data indicated that obsessive-compulsive behavior and phobic anxiety of university students can be predicted by the way they frame the concept of God. Moreover, the findings revealed that the male students who had a positive concept of God were lower in phobic anxiety (r=24; p<0.05). However, the female univesity students who had a positive concept of God were lower in obsessive-compulsive behavior (r=28; p<0.05).
Conclusion: According to the findings, it can be concluded that obsessive-compulsive behavior and phobic anxiety of university students are subject to their concept of God.

Author attribution using profile classifiers
No full textA atribuição autoral (AA) busca identificar um autor de texto a partir de um conjunto de autores conhecidos. Autores deixam rastros em seus textos e é possível identificar características sociolinguísticas baseadas no estilos de escrita refletidos no texto destes autores. A atribuição autoral está cada vez mais demonstrando importância para diversas atividades sociais, em especial para a análise forense. Os trabalhos envolvendo AA demonstram resultados modestos e motivam a exploração de diferentes técnicas para melhorar a acurácia dos modelos atuais. A partir desses pontos, o presente trabalho apresenta uma proposta de pesquisa em nível de mestrado no campo de processamento de língua natural (PLN), com ênfase em AA, com o objetivo geral de melhorar o desempenho de classificadores de atribuição autoral utilizando técnicas de caracterização autoral (CA)Author attribution (AA) seeks to identify a text author from a set of known authors. Authors leave traces in their texts and it is possible to identify sociolinguistic characteristics based on the writing styles reflected in the text of these authors. Author attribution is increasingly showing importance for various social activities, especially forensic analysis. Studies involving AA show modest results and motivate the exploration of different techniques to improve the accuracy of current models. From these perspective, this project presents a master\'s level research proposal in the field of natural language processing (NLP), with an emphasis in AA, with the general objective of improving the performance of AA classifiers using author profiling technique

Continuous molecular absorption was observed from 3500{\AA} to 1700{\AA} and ion chamber measurement indicate that this absorption is due to an ionization continuum. Ion current peaks were also seen between 2413{\AA} and 3500{\AA} at wavelengths corresponding to the series absorption lines of the sodium atom. Curves will be presented showing the variation with wavelength of both the atomic cross section and the relative molecular cross section.
