Handwriter identification aims to simplify the task of forensic experts by providing them with semi-automated tools in order to enable them to narrow down the search to determine the final identification of an unknown handwritten sample. An identification algorithm aims to produce a list of predicted writers of the unknown handwritten sample ranked in terms of confidence measure metrics for use by the forensic expert will make the final decision.Most existing handwriter identification systems use either statistical or model-based approaches. To further improve the performances this paper proposes to deploy a combination of both approaches using Oriented Basic Image features and the concept of graphemes codebook. To reduce the resulting high dimensionality of the feature vector a Kernel Principal Component Analysis has been used. To gauge the effectiveness of the proposed method a performance analysis, using IAM dataset for English handwriting and ICFHR 2012 dataset for Arabic handwriting, has been carried out. The results obtained achieved an accuracy of 96% thus demonstrating its superiority when compared against similar techniques.  相似文献

Cultural Identification and Religious Identification Contribute Differentially to the Adaptation of Australian Adolescent Muslims     

《Int J Intercult Relat》2016

Australian Muslims are generally perceived as a devalued group in Australia and the public attitudes towards them are generally negative. This context raises questions about belonging and adaptation among Australian adolescent Muslims. The current study investigated how adolescent Muslims relate to their heritage culture, religion, and Australian culture, and which of these three factors is most important to adolescent Muslims’ psychological and socio-cultural adaptation. The study employed a mixed-method design. A total of 321 high school Muslim students (149 males and 172 females) aged between 14 and 18 years completed self-report questionnaires, and a subset sample of 18 students in the same age range, evenly split between males and females, participated in semi-structured interviews. The study revealed a hierarchical pattern of identification among Australian adolescent Muslims, with attachment to their religion being the most important, followed by heritage culture identification and being Australian in third place. Australian adolescent Muslims’ religious identification was perceived overall as more crucial to their socio-cultural and psychological adaptation, than their heritage culture identification or Australian identification. There was an overall modest contribution of Australian identification to adolescent Muslims’ adaptation. This might be connected with the relatively less attachment they show to their Australian identity due maybe to perception of being the target of prejudice, an issue that can be addressed by implementation of prejudice reduction strategies.  相似文献

Key somatic variables associated with,and differences between the 4 swimming strokes     

Alan M. Nevill  Yassine Negra  Tony D. Myers  Senda Sammoud  Helmi Chaabene 《Journal of sports sciences》2020,38(7):787-794

ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).  相似文献

Dialectics of design: how ideas of ‘good design’ change     

《普罗米修斯》2012,30(1):29-39

This paper advances a first‐pass theory of change in the styling of objects of domestic utility. It is based on the idea that the expressive potential of design for the maker, the user and the designer exists in tension with other desirable properties of the designed artefact. Respectively these are mass availability, conformity to professionally‐defined ideas of good taste, and the demands of function and marketability. The theory is illustrated by reference to the emergence and subsequent dilution of three design movements; Arts and Crafts, Art Nouveau and certain versions of Modernism.  相似文献

中国人性别角色量表的建构及其与心理社会适应的关系     

王登峰  崔红 《西南师范大学学报(人文社会科学版)》2007,33(4):1-9

本研究的目的是建立中国人的性别角色量表，并探索不同性别角色类型的个体其心理社会适应水平的特点。研究一根据5000多名被试对中国人人格量表项目的反应挑选出男女被试有显著差异的项目，经过因素分析建立了各由30个项目组成，分别由七个和六个因素构成的中国人男性化和女性化量表，并据此将被试划分为未分化、女性化、男性化和双性化四种性别角色类型。研究二则比较了不同性别角色类型与心理健康的关系，表明在中国被试中双性化的个体心理社会适应水平最低、女性化个体心理社会适应最好。这一结果与Bem关于双性化的假设是截然相反的。本研究从中国文化与性别角色的关系对这一结果进行了解释，提出了中国文化是女性化文化，同时又是反男性化文化的假设，并对进一步研究的方向进行了讨论。  相似文献
