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   

Kinematic analysis of the drag flick in field hockey     

Rony Ibrahim  Gert S. Faber  Jaap H. van Dieën 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):45-57

Attaining high speed of the stick head and consequently of the ball is essential for successful performance of the drag flick in field hockey, but the coordination pattern used to maximise stick head speed is unknown. The kinematics of the drag flick was studied in ten elite hockey players who performed twenty shots each towards a target located 1.5 m high. A 150 Hz active marker motion analysis system was used, alongside two force plates to detect foot touchdown. Angular velocity and contribution to stick endpoint speed of upper body joints were analysed. Repeated measures ANOVA was used to compare timing of onset and peak angular velocities between joints. Participants used a kinematic pattern that was close to a proximal-to-distal sequence. Trunk axial rotation and lateral rotation towards the target, right wrist flexion and left wrist extension were the main contributors to stick endpoint speed. Coaches should emphasise trunk rotations and wrist flexion and extension movements for maximising stick head speed. Given the high level of the participants in this study, the coordination of joints motions, as reported here, can serve as a guideline for drag flick training.  相似文献   

The Effectiveness of the Responsive Teaching Parent-mediated Developmental Intervention Programme in Turkey: A pilot study     

Ozcan Karaaslan  Ibrahim Diken  Gerald Mahoney 《International Journal of Disability, Development & Education》2011,58(4):359-372

The case study was conducted to examine the feasibility of an early intervention curriculum called Responsive Teaching with two five-year-old children from Turkey who had significant developmental delays. This study determined whether Turkish mothers might be successful in learning to become more responsive to their children, and whether this would result in significant improvements in their children’s development. Both dyads received 28 individual parent–child intervention sessions which were conducted over a four-month period of time. Pre-, mid-, and post-assessments indicated improvements in the mothers’ responsiveness to their children and the children’s levels of engagement with their parents. There were also improvements in the children’s language and personal social development. Mothers reported that Responsive Teaching helped them learn to interact more effectively with their children and that this resulted in longer and more enjoyable interactions with them. Results from this investigation are discussed in terms of their implications for providing developmental services to preschool-aged children with disabilities in Turkey.  相似文献   

Modelling parenting styles,moral intelligence,academic self-efficacy and learning motivation among adolescents in grades 7–11     

Amal Alhadabi  Said Aldhafri  Hussain Alkharusi  Ibrahim Al-Harthy  Marwa Alrajhi  Hafidha AlBarashdi 《Asia Pacific Journal of Education》2019,39(1):133-153

The current study investigated the associations between three maternal and paternal parenting styles, moral intelligence, academic self-efficacy and learning motivation in three serial mediation models. Omani adolescents enrolled in 7th to 11th grades (N = 296) responded to an online survey containing demographic items and scales measuring the variables noted above. Results of Path Analysis indicated that the three models had a good overall fit. In detail, the three paternal styles (authoritative, authoritarian and permissive) had direct associations with moral intelligence and indirect associations with learning motivation. However, only two maternal parenting styles (i.e., authoritative and authoritarian) correlated directly with learning motivation and these two styles did not associate with moral intelligence. All effects were in the hypothesized direction except the effect of authoritative maternal and paternal styles. Moral intelligence had a positive direct correlation with students’ academic self-efficacy and learning motivation. Moral intelligence also mediated the negative associations between three types of fathers’ parenting styles and students’ motivation. Academic self-efficacy had a positive association with students’ motivation. These findings provided useful insights about the various association between external factors (e.g., parenting styles), internal factors (i.e., moral intelligence and self-efficacy) and students’ motivation among adolescents in middle and high schools.  相似文献

Age-Dependent Changes in Glutathione-S-Transferase: Correlation with Total Plasma Antioxidant Potential and Red Cell Intracellular Glutathione     

Maurya PK  Rizvi SI 《Indian journal of clinical biochemistry : IJCB》2010,25(4):398-400

The correlation between antioxidant capacity and oxidative damage during aging has been reported in several tissues in different species. Glutathione-S-transferases (GST) can metabolise endogenous and exogenous toxins and carcinogens by catalysing the conjugation of diverse electrophiles with reduced glutathione (GSH). We observe a significant (P < 0.001) increase in plasma GST activity as a function of human age (r = 0.5675). A significant (P < 0.001) positive correlation (r = 0.8979) is observed between GST activity and total plasma antioxidant potential measured as ferric reducing ability of the plasma (FRAP). GST activity and red cell intracellular GSH also show a significant positive correlation (r = 0.7014). We hypothesize that the increased activity of plasma GST is a manifestation of increased generation of ROS and a concomitant decrease in the level of plasma antioxidant capacity during aging.  相似文献   

Effect of perceived ease of use on librarians' e-skills: Basis for library technology acceptance intention     

Roland Izuagbe  Nurudeen Ademola Ibrahim  Lilofa Osamienfa Ogiamien  Olajumoke Rebecca Olawoyin  Nwanne Mary Nwokeoma  Promise Ifeoma Ilo  Odaro Osayande 《Library & information science research》2019,41(3):100969

Despite the widespread application of technology in the 21st century, making informed decisions regarding its acceptance in organisations is a function of several factors, particularly in developing countries, due to factors such as rising cost of the information technology infrastructure and low technological exposure. A model that incorporated perceived ease of use (PEOU) and e-Skills to examine librarians' intention for actual library technology acceptance was tested. The correlational research design, along with a multistage sampling procedure, was applied to select samples to reduce the sample to a manageable proportion. Professional librarians and library officers in four university libraries provided the data for the study. Results showed that e-Skill is the model's strongest determinant of technology acceptance intention among librarians. Also, PEOU will significantly moderate librarians' intention towards library technology acceptance when e-Skills are insufficient. From these outcomes, the understanding of the determinants of behavioural intention captured in the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAT) is extended and refined.  相似文献   

Palestinian media landscape: Experiences,narratives, and agendas of journalists under restrictions     

Ibrahim Hazboun  Ifat Maoz  Menahem Blondheim 《The Communication Review》2019,22(1):1-25

This study aims to increase our understanding of the dynamics of the Palestinian media and the conditions and circumstances in which they work, including both the conflict with Israel and the internal political strife within Palestinian society. It is based on the use of qualitative research methods and was conducted in two stages. First, we performed a mapping of Palestinian media outlets. Data on these Palestinian media outlets were collected online from the West Bank-based Palestinian Authority’s Ministry of Information website, the Gaza-based Hamas government’s Ministry of Information website, and statements published by Palestinian media outlets on their websites describing their affiliation and ownership. Second, to gain a more in-depth understanding of the dynamics and experience of practicing journalism in a situation of asymmetrical conflict, semistructured in-depth interviews were conducted with 25 professional local Palestinian journalists working for local media outlets in the Gaza Strip, the West Bank, and East Jerusalem. Through this study we aim to learn more about how groups shape and express their narratives and agendas through the media when restricted by the conditions, pressures, and limitations of asymmetrical conflict.  相似文献   

A corpus-based discourse analysis of the vision and mission statements of universities in Turkey     

Ibrahim Efe 《高等教育研究与发展》2015,34(6):1110-1122

This article presents findings from a corpus-assisted discourse analysis of mission and vision statements of 105 state and 66 private/foundation universities in Turkey. The paper combines a corpus-based approach with critical discourse analysis to interpret the data in relation to its institutional as well as socio-political context. It argues that the mission and vision statements are marked by a need for reassuring their legitimacy and the demands of a growing tertiary market. The historical and cultural backgrounds of the development of universities in Turkey, as well as political and economic conditions, are also decisive in the shaping of mission and vision statement of universities.  相似文献
