In computer security parlance, a hacker is an individual who actively seeks and takes advantage of flaws and weaknesses of a computer network or system. In recent years, one has seen the rise of hacking, often as a form of protest and retaliation for reasons ranging from political to social, but the question remains as to what really motivates an individual to hack a computer network? Using the Q-method, the study aimed to develop a classification of the motivation of computer hackers. This was done with the use of 43 participants who were subjected to preliminary interviews and the sorting method. The statements from the interviews were categorized that resulted in seven conceptual themes, namely social-positive, social-negative, intellectual gain, self-satisfaction, economic rewards, technological-positive and technological-negative. From these themes, three distinct profiles emerged and were used to describe the motivation of hackers. 相似文献

Androgyny in Liking and in Being Liked Are Antecedent to Well-Being in Pre-Adolescent Boys and Girls
The present study is a two-wave longitudinal study of the concurrent and prospective associations between patterns of same- and other-gender liking and well-being in a sample of 403 fifth and sixth-grade girls and boys from Montréal Québec, Canada that was used to examine Sandra Bem’s perspective that androgyny is related to well-being. In our study androgyny was operationally defined as (a) the combination of liking for same- and other-gender peers and (b) the combination of being liked by same- and other-gender peers. Well-being was indexed with a measure of the self-concept. Findings drawn from analyses conducted with structural equation modeling showed that androgynous liking was an antecedent and a consequence of well-being. Specifically (a) Time 1 (T1) well-being was a predictor of how much girls and boys liked same-gender and other-gender peers at Time 2 (T2) whereas T2 well-being was predicted by how much girls and boys liked same- and other-gender peers at T1 and (b) T2 well-being was predicted by how much girls and boys were liked by same-gender and other-gender peers. These findings are discussed according to the dynamics of experiences with peers from one’s own gender and the other-gender. 相似文献

An investigation of the psychometric properties of the German version of the Group Questionnaire (GQ; Krogel 2009) is described. The GQ is a self-report instrument economically enabling the assessment of helpful aspects of relationships within small groups. Due to the limited length of the questionnaire it provides a tool of monitoring bonding to the group, the quality of the working relationship as well as negative aspects during group treatment. One advantage of the GQ is that it measures relationships on three different relational levels (group members, group leader and the group as a whole). Following a test of the multidimensional structure of the GQ-D using data from a multisite study (N=438) with structural equation models, the GQ-D was validated using other process measures. The GQ-D proved to be an objective, valid and reliable measure to assess relevant therapeutic relationships within groups. 相似文献

Health-related quality of life (QoL) is reduced in patients with recurrent vasovagal (VVS) or unexplained (US) syncope. Little
is known regarding these patients’ QoL as pertains to their capacity to attain their life goals. Factors influencing QoL,
such as sex, syncope type and illness representations have not been studied. Our objective is to examine the relationship
between illness representations and QoL, as well as possible sex and syncope type differences. One hundred and four patients
undergoing tilt-table testing (TTT) for recurrent syncope were interviewed one month before TTT, using questionnaires. Data
were analysed using ANCOVAs, a-priori Helmert contrasts for illness representations, and regressions. Patients with US had
a poor QoL compared to those with VVS [F(1, 91) = 10.46; p < 0.01], particularly in men (p < 0.01). Patients with higher perceived syncope severity showed an impoverished QoL relative to those with less severe perceptions
[F(1, 91) = 5.47; p < 0.05]. A hierarchical regression revealed that illness representations mediate the impact of lifetime number of syncope
on QoL. In conclusion, QoL is reduced in these patients, and is influenced by illness representations. Helping patients change their
perceptions about their syncope may be an efficient way to promote QoL. 相似文献

Two experiments examined whether 4-, 6-, and 10-month-old infants process natural looking faces by feature, i.e. processing internal facial features independently of the facial context or holistically by processing the features in conjunction with the facial context. Infants were habituated to two faces and looking time was measured. After habituation they were tested with a habituation face, a switch-face, or a novel face. In the switch-faces, the eyes and mouth of the habituation faces were switched. The results showed that the 4-month-olds processed eyes and mouth by feature, whereas the 10-month-olds processed both features holistically. The 6-month-olds were in a transitional stage where they processed the mouth holistically but the eyes still as a feature. Thus, the results demonstrated a shift from featural to holistic processing in the age range of 4 to 10 months. 相似文献

The right-hemisphere hypothesis of deep dyslexia has received support from functional imaging studies of acquired deep dyslexia following damage to the left cerebral hemisphere, but no imaging studies of cases of developmental deep dyslexia, in which brain damage is not suspected, have been reported. In this paper, we report the first evidence of right hyperactivation in an adult case of developmental deep dyslexia. Hyperactivation was observed in the right inferior frontal cortex during functional magnetic resonance imaging (fMRI) of the oral reading of imageable content words and nonwords to which imageable lexical responses were frequently made. No evidence of right hyperactivation was observed in the oral reading of function words, nor during the naming of imageable words in response to pictured objects. The results reveal strategic and selective use of right-hemisphere functions for particular types of written stimuli. We propose that children with developmental deep dyslexia compensate for their lack of phonological skills by accessing right-hemisphere imageable associations that provide a mnemonic for linking written forms to spoken names. 相似文献

Mathematics difficulties are common in both children and adults, and they can have a great impact on people's lives. A specific learning disorder in mathematics (SLDM or developmental dyscalculia) is a special case of persistent mathematics difficulties, where the problems with maths cannot be attributed to environmental factors, intellectual disability, or mental, neurological or physical disorders. The aim of the current study was to estimate the prevalence rate of SLDM, any gender differences in SLDM, and the most common comorbid conditions. The DSM-5 provides details regarding these only for specific learning disorders in general, but not specifically for SLDM. We also compared the prevalence rates obtained on the basis of the DSM-IV and DSM-5 criteria. We investigated the performance of 2,421 primary school children on standardized tests of mathematics, English, and IQ, and several demographic factors over the primary school years. We applied the DSM-5 diagnostic criteria to identify children with a potential diagnosis of SLDM. Six per cent of our sample had persistent, severe difficulties with mathematics, and, after applying the exclusion criteria, 5.7% were identified as having an SLDM profile. Both persistent maths difficulties and consistently exceptionally high performance in maths were equally common in males and females. About half of the children with an SLDM profile had some form of language or communication difficulty. Some of these children also had a diagnosis of autism, social, emotional, and behavioural difficulties or attention deficit and hyperactivity disorder. Our findings have important implications for research and intervention purposes, which we discuss in the study. 相似文献

Few studies have assessed the effects of stress on in vivo platelet activation. In the present study, hypobaric hypoxia induced by rapid decompression during high-altitude simulated flight in a hypobaric chamber was used to evaluate the effects of environmental stress on salivary cortisol and urinary thromboxane metabolite (TXM) excretion, a noninvasive marker of in vivo platelet function. Twenty-one male aviators (mean ± SD age = 36 ± 7 years) experiencing hypoxia by removing their oxygen mask for 4-5 min during a simulated flight to 25,000 ft (7,620 m; pO(2) = 59.17 mmHg) and a matched control group of thirteen flying instructors wearing oxygen masks during the challenge, were studied. Hypobaric hypoxia induced a transient significant increase (P < 0.001) in the aviators' salivary cortisol concentration; the overall pattern of diurnal cortisol fluctuation was maintained in both groups. Urinary TXM showed a significant ~30% reduction (P < 0.01) after the chamber session in aviators exposed to hypobaric hypoxia, but not in controls. A significant inverse correlation was found between salivary cortisol and urinary TXM in aviators (r = - 0.64, P = 0.0015). Salivary cortisol was a significant predictor (P < 0.001) for urinary TXM concentrations in aviators. In conclusion, here we observed that an acute stress-induced salivary cortisol increase was associated with reduced urinary thromboxane biosynthesis, providing the first indirect evidence for an inhibitory effect of acute stress on in vivo platelet function. 相似文献

This investigation aims at adapting the test for Efficient Personality in educational contexts to Chilean reality. This instrument measures the construct efficient personality , made up of four levels of the self: strengths, requests, challenges and relationships. The original version has 58 items. In order to adapt it to our reality, 30 items were modified. The instrument was applied to a sample of 594 third and fourth secondary level students from four educational institutions of Vi?a del Mar. The new version of the instrument (23 items) presents a .85 reliability coefficient. The factorial analysis shows a structure of four basic factors which explain 50.42 % of the total variance. These factors, which are very similar those proposed in the original instrument, are named as academic self realization, social self realization, solving efficiency, and self steem. The second order factors analysis reveals a single factors structure that explains 43,28 % of the total variance, thus confirming the presence of the only factor that would correspond to the efficient personality construct presented. 相似文献

During the June 2001, eighth biennial meeting of the Society for Community Research and Action in Atlanta, a wide variety of community psychologists across generations attended a tribute in honor of James Gordon Kelly. What follows is an attempt to capture the spirit of the afternoon tribute as expressed through remarks made by colleagues and readings of letters sent by those unable to attend. The wide range of individuals represented here attests to the many additive ways in which Jim has cared about the field of community psychology and has contributed to its essence. Three additional invited contributions are included wherein Dick Reppucci, Rhona Weinstein, and Julian Rappaport reflect on the influence of Jim on their own career and on the development of the field. 相似文献
