Feature selection using Ant Colony Optimization (ACO) and Road Sign Detection and Recognition (RSDR) system

Road Sign Detection and Recognition (RSDR) is aimed to enable drivers maintain basic functionality with the aim of identifying and notifying driver through the existing restrictions so that the process is a success on the present widened road. Examples for RSDR include ‘traffic light ahead’ or ‘pedestrian crossing’ signs. An innovative RSDR system has been introduced which comprises of pre-processing, edge detection, feature extraction, features selection and Ensemble Fuzzy Support Vector Machine (EFSVM) classifier. Feature selection is carried out successfully by deployment of Ant Colony Optimization (ACO) algorithm to determine most prominent and definitive features. These features are then fed into the ensemble SVM to enable both road side traffic detection as well as recognition. Suggested system’s performance is analyzed and evaluated with respect to road signs having a capable recognition rate.     

The psychological coping,learning potential and career preferences profiles of operational force military candidates

The aim of this study was to profile the psychological coping, learning potential and career-related interests of 251 candidates for operational force military selection for the South African National Defence Force (SANDF) – 26 of whom were successful in the selection. Data on their sense of meaning, learning potential and career-related interest were gathered using standardised measures supplemented with open-ended responses. The data were analysed to compare the profiles of the successful candidates against those not selected. The selected group showed significantly higher mean scores on meaningfulness and learning potential, and lower scores for career-related interest in law and medicine. Findings suggest that psychological coping, learning potential and career-related preference information can be used to refine the selection of operational force military candidates.     

个体特征因素对师徒之间选择倾向的影响

师徒的相互选择过程是师徒关系研究中的一个重要问题。本文采用三个实验探讨了影响师徒相互选择倾向的个体特征因素。实验一和实验二探讨了徒弟选师傅时,师傅的外向性、成就动机水平、管理职务和性别一致性对徒弟选择师傅倾向的影响。实验三探讨了师傅选择徒弟时,徒弟的外向性、成就动机水平和性别一致性对师傅选择徒弟倾向的影响。实验结果表明在徒弟选择师傅时,师傅的外向性、成就动机、管理职务,是影响因素;在师傅选择徒弟时,徒弟的外向性、成就动机水平是影响因素。     

“To‐be‐forgotten” statements become less true: Memory processes involved in selection and forgetting lead to truthfulness changes of ambiguous sentences

What happens when people try to forget something? What are the consequences of instructing people to intentionally forget a sentence? Recent studies employing the item‐method directed forgetting paradigm have shown that to‐be‐forgotten (TBF) items are, in a subsequent task, emotionally devaluated relative to to‐be‐remembered (TBR) items, an aftereffect of memory selection (Vivas, Marful, Panagiotidou & Bajo, 2016). As such, distractor devaluation by attentional selection generalizes to memory selection. In this study, we use the item‐method directed forgetting paradigm to test the effects of memory selection and inhibition on truth judgments of ambiguous sentences. We expected the relative standing of an item in the task (i.e., whether it was instructed to be remembered or forgotten) to affect the truthfulness value of that item, making TBF items less valid/truthful than TBR items. As predicted, ambiguous sentences associated with a “Forget” cue were subsequently judged as less true than sentences associated with a “Remember” cue, suggesting that instructions to intentionally forget a statement can produce changes in the validity/truthfulness of that statement. To our knowledge, this is the first study to show an influence of memory processes involved in selection and forgetting on the perceived truthfulness of sentences.     

On being guided – a typology of career guidance in EU discourses*

With this article we want to illustrate how the central publications of the European Union legitimate a role of Career Guidance Services (CGS) that help in establishing a desired form of social order. Using the Sociology of Knowledge Approach to Discourse, we reconstructed four typical metaphorical conceptualisations of CGS that go along with desirable and taken-for-granted subject positions. The results reveal the assigned active role of CGS in establishing a specific vision of and in transforming the European society. We conclude by outlining the ways in which critique is expressed within the discourse and by highlighting the inherent ambivalences of these practices of critique.     

What did Popper learn from Lakatos?

The canonical version of the history of twentieth century philosophy of science tells us that Lakatos was Popper’s disciple, but it is rarely mentioned that Popper would have learned anything from Lakatos. The aim of this paper is to examine Lakatos’ influence on Popper’s philosophical system and to argue that Lakatos did have an important, yet somewhat unexpected, impact on Popper’s thinking: he influenced Popper’s evolutionary model for ‘progress’ in science. And Lakatos’ influence sheds new light on why and how Popper continually revised one of the central claims of his philosophy of science: the evolutionary account of scientific theory change.

有关条件推理中概率效应的实验研究

通过预备实验选取了四种不同条件概率的条件规则和四种不同前后件概率组合的条件规则作为实验材料,以大学生为被试,考察了两种概率因素(条件概率和前后件概率)对条件推理的演绎形式(MP、DA、AC、MT)以及变通形式(四卡问题)的影响。结果表明,两种概率因素对四种条件推理的影响都非常显著,研究进一步证实了人们对四种推理的认可程度主要与范畴前提的概率成正比的结论;但概率因素对四卡问题的解决影响不明显。     

面试中的AIM问题及改进对策

面试、尤其是结构化面试是企业、政府机关及一些非盈利性组织选拔人才的最常用的工具。随着应聘者的面试经验增加,面试选拔优秀人才的难度也在增加。本文借鉴国外“印象控制”（AIM）概念,就如何克服主试者的主观偏见、第一印象偏见、次序对比偏见等面试误差、提高面试的信度和效度作了探索。
