Systemizers are better code-breakers: self-reported systemizing predicts code-breaking performance in expert hackers and naïve participants

Studies on hacking have typically focused on motivational aspects and general personality traits of the individuals who engage in hacking; little systematic research has been conducted on predispositions that may be associated not only with the choice to pursue a hacking career but also with performance in either naïve or expert populations. Here, we test the hypotheses that two traits that are typically enhanced in autism spectrum disorders—attention to detail and systemizing—may be positively related to both the choice of pursuing a career in information security and skilled performance in a prototypical hacking task (i.e., crypto-analysis or code-breaking). A group of naïve participants and of ethical hackers completed the Autism Spectrum Quotient, including an attention to detail scale, and the Systemizing Quotient (Baron-Cohen et al., 2001, 2003). They were also tested with behavioral tasks involving code-breaking and a control task involving security X-ray image interpretation. Hackers reported significantly higher systemizing and attention to detail than non-hackers. We found a positive relation between self-reported systemizing (but not attention to detail) and code-breaking skills in both hackers and non-hackers, whereas attention to detail (but not systemizing) was related with performance in the X-ray screening task in both groups, as previously reported with naïve participants (Rusconi et al., 2015). We discuss the theoretical and translational implications of our findings.

The effects of productivity on profitability: a case study at firm level using an activity-based costing approach

Productivity and profitability are important concepts and measures describing the performance and success of a firm. We know that increase in productivity decreases the costs per unit produced and leads to better profitability. This common knowledge is not, however, enough in the modern business environment. Productivity improvement is one means among others for increasing the profitability of actions. There are many means to increase productivity. The use of these means presupposes operative decisions and these decisions presuppose informationabout the effects of these means. Productivity improvement actions are in general made at floor level with machines, cells, activities and human beings. Profitability is most meaningful at the level of the whole firm. It has been very difficult or even impossible to analyze closely enough the economical aspects of thechanges at floor level with the traditional costing systems. New ideas in accounting have only recently brought in elements which make it possible to considerthese phenomena where they actually happen. The aim of this study is to supportthe selection of objects to productivity improvement, and to develop a method to analyze the effects of the productivity change in an activity on the profitability of a firm. A framework for systemizing the economical management of productivity improvement is developed in this study. This framework is a systematical way with two stages to analyze the effects of productivity improvement actions inan activity on the profitability of a firm. At the first stage of the framework, a simple selection method which is based on the worth, possibility and the necessity of the improvement actions in each activity is presented. This method is called Urgency Analysis. In the second stage it is analyzed how much a certain change of productivity in an activity affects the profitability of a firm. A theoretical calculation model with which it is possible to analyze the effects of a productivity improvement in monetary values is presented. On the basis of this theoretical model a tool is made for the analysis at the firm level. The usefulness of this framework was empirically tested with the data of the profit center of one medium size Finnish firm which operates in metal industry. It is expressedthat the framework provides valuable information about the economical effects of productivity improvement for supporting the management in their decision making.

Elinkeinoyhtiön asiakaspalveluprosessien kuvaaminen ja kehittäminen

Diplomityön tavoitteena oli selkeyttää ja yhtenäistää case-yrityksen asiakaspalveluprosesseja kuvaamalla ne ja kehittämällä niitä. Case-yhtiönä oli seudullinen elinkeinoyhtiö, joka tarjoaa asiakkailleen tietointensiivisiä asiantuntija- ja neuvontapalveluita. Diplomityön lopputuloksena oli tarkoitus luoda yhtenäiset asiakaspalveluprosessimallit case-yritykselle. Tutkimuksessa vastattiin kirjallisuuskatsauksen avulla kysymyksiin, kuinka asiakaspalveluprosesseja voidaan kehittää ja millä menetelmillä prosesseja voidaan kuvata. Tämän jälkeen tutkittiin, miten case-yritys voi kehittää asiakaspalveluprosessejaan soveltamalla näitä menetelmiä. Selvisi, että palveluprosessin kehittäminen edellyttää käytännössä palvelun tuotteistamista, joka voidaan jakaa kolmeen osa-alueeseen: 1) palvelun määrittäminen ja standardointi, 2) palvelun ja asiantuntijuuden aineellistaminen ja konkretisointi ja 3) prosessien ja metodien systematisointi ja standardisointi. Asiantuntijapalveluja on vaikea tai mahdoton standardoida sellaisenaan, mutta ne voidaan tuotteistaa modulaarisesti. Palveluprosessien systematisoimiseen sopivin työkalu on niiden kuvaaminen service blueprinting -menetelmällä. Tutkimus on laadultaan kvalitatiivinen kuvaileva tapaustutkimus. Tutkimuksen empiirisessä on käytetty aineistonhankintatapoina puolistrukturoitua kyselyä, teemahaastatteluja, osallistuvaa havainnointia ja dokumenttien tutkimista. Näiden aineistojen analysoinnin tuloksena saatiin case-yritykselle kehitettyä yhtenäinen malli yleisestä asiakaspalveluprosessista ja kuvattua keskeisimpien palvelujen asiakaspalveluprosessit service blueprinting -menetelmällä.

Talent in autism: hyper-systemising, hyper-attention to detail and sensory hypersensitivity

We argue that hyper-systemizing predisposes individuals to show talent, and review evidence that hyper-systemizing is part of the cognitive style of people with autism spectrum conditions (ASC). We then clarify the hyper-systemizing theory, contrasting it to the weak central coherence (WCC) and executive dysfunction (ED) theories. The ED theory has difficulty explaining the existence of talent in ASC. While both hyper-systemizing and WCC theories postulate excellent attention to detail, by itself excellent attention to detail will not produce talent. By contrast, the hyper-systemizing theory argues that the excellent attention to detail is directed towards detecting 'if p, then q' rules (or [input-operation-output] reasoning). Such law-based pattern recognition systems can produce talent in systemizable domains. Finally, we argue that the excellent attention to detail in ASC is itself a consequence of sensory hypersensitivity. We review an experiment from our laboratory demonstrating sensory hypersensitivity detection thresholds in vision. We conclude that the origins of the association between autism and talent begin at the sensory level, include excellent attention to detail and end with hyper-systemizing.

A behavioral comparison of male and female adults with high functioning autism spectrum conditions

Autism spectrum conditions (ASC) affect more males than females in the general population. However, within ASC it is unclear if there are phenotypic sex differences. Testing for similarities and differences between the sexes is important not only for clinical assessment but also has implications for theories of typical sex differences and of autism. Using cognitive and behavioral measures, we investigated similarities and differences between the sexes in age- and IQ-matched adults with ASC (high-functioning autism or Asperger syndrome). Of the 83 (45 males and 38 females) participants, 62 (33 males and 29 females) met Autism Diagnostic Interview-Revised (ADI-R) cut-off criteria for autism in childhood and were included in all subsequent analyses. The severity of childhood core autism symptoms did not differ between the sexes. Males and females also did not differ in self-reported empathy, systemizing, anxiety, depression, and obsessive-compulsive traits/symptoms or mentalizing performance. However, adult females with ASC showed more lifetime sensory symptoms (p = 0.036), fewer current socio-communication difficulties (p = 0.001), and more self-reported autistic traits (p = 0.012) than males. In addition, females with ASC who also had developmental language delay had lower current performance IQ than those without developmental language delay (p<0.001), a pattern not seen in males. The absence of typical sex differences in empathizing-systemizing profiles within the autism spectrum confirms a prediction from the extreme male brain theory. Behavioral sex differences within ASC may also reflect different developmental mechanisms between males and females with ASC. We discuss the importance of the superficially better socio-communication ability in adult females with ASC in terms of why females with ASC may more often go under-recognized, and receive their diagnosis later, than males.

Why are autism spectrum conditions more prevalent in males?

Autism Spectrum Conditions (ASC) are much more common in males, a bias that may offer clues to the etiology of this condition. Although the cause of this bias remains a mystery, we argue that it occurs because ASC is an extreme manifestation of the male brain. The extreme male brain (EMB) theory, first proposed in 1997, is an extension of the Empathizing-Systemizing (E-S) theory of typical sex differences that proposes that females on average have a stronger drive to empathize while males on average have a stronger drive to systemize. In this first major update since 2005, we describe some of the evidence relating to the EMB theory of ASC and consider how typical sex differences in brain structure may be relevant to ASC. One possible biological mechanism to account for the male bias is the effect of fetal testosterone (fT). We also consider alternative biological theories, the X and Y chromosome theories, and the reduced autosomal penetrance theory. None of these theories has yet been fully confirmed or refuted, though the weight of evidence in favor of the fT theory is growing from converging sources (longitudinal amniocentesis studies from pregnancy to age 10 years old, current hormone studies, and genetic association studies of SNPs in the sex steroid pathways). Ultimately, as these theories are not mutually exclusive and ASC is multi-factorial, they may help explain the male prevalence of ASC.

Individual differences in brain structure underpin empathizing–systemizing cognitive styles in male adults

Individual differences in cognitive style can be characterized along two dimensions: ‘systemizing’ (S, the drive to analyze or build ‘rule-based’ systems) and ‘empathizing’ (E, the drive to identify another's mental state and respond to this with an appropriate emotion). Discrepancies between these two dimensions in one direction (S > E) or the other (E > S) are associated with sex differences in cognition: on average more males show an S > E cognitive style, while on average more females show an E > S profile. The neurobiological basis of these different profiles remains unknown. Since individuals may be typical or atypical for their sex, it is important to move away from the study of sex differences and towards the study of differences in cognitive style. Using structural magnetic resonance imaging we examined how neuroanatomy varies as a function of the discrepancy between E and S in 88 adult males from the general population. Selecting just males allows us to study discrepant E-S profiles in a pure way, unconfounded by other factors related to sex and gender. An increasing S > E profile was associated with increased gray matter volume in cingulate and dorsal medial prefrontal areas which have been implicated in processes related to cognitive control, monitoring, error detection, and probabilistic inference. An increasing E > S profile was associated with larger hypothalamic and ventral basal ganglia regions which have been implicated in neuroendocrine control, motivation and reward. These results suggest an underlying neuroanatomical basis linked to the discrepancy between these two important dimensions of individual differences in cognitive style.

Genetic variation in GABRB3 is associated with Asperger syndrome and multiple endophenotypes relevant to autism.

BACKGROUND: Autism spectrum conditions (ASC) are associated with deficits in social interaction and communication, alongside repetitive, restricted, and stereotyped behavior. ASC is highly heritable. The gamma-aminobutyric acid (GABA)-ergic system has been associated consistently with atypicalities in autism, in both genetic association and expression studies. A key component of the GABA-ergic system is encoded by the GABRB3 gene, which has been previously implicated both in ASC and in individual differences in empathy. METHODS: In this study, 45 genotyped single nucleotide polymorphisms (SNPs) within GABRB3 were tested for association with Asperger syndrome (AS), and related quantitative traits measured through the following tests: the Empathy Quotient (EQ), the Autism Spectrum Quotient (AQ), the Systemizing Quotient-Revised (SQ-R), the Embedded Figures Test (EFT), the Reading the Mind in the Eyes Test (RMET), and the Mental Rotation Test (MRT). Two-loci, three-loci, four-loci haplotype analyses, and one seven-loci haplotype analysis were also performed in the AS case--control sample. RESULTS: Three SNPs (rs7180158, rs7165604, rs12593579) were significantly associated with AS, and two SNPs (rs9806546, rs11636966) were significantly associated with EQ. Two SNP-SNP pairs, rs12438141-rs1035751 and rs12438141-rs7179514, showed significant association with variation in the EFT scores. One SNP-SNP pair, rs7174437-rs1863455, was significantly associated with variation in the MRT scores. Additionally, a few haplotypes, including a 19 kb genomic region that formed a linkage disequilibrium (LD) block in our sample and contained several nominally significant SNPs, were found to be significantly associated with AS. CONCLUSION: The current study confirms the role of GABRB3 as an important candidate gene in both ASC and normative variation in related endophenotypes.

A dimensão social do desenho: um estudo sobre as interações no processo de (re) construção imagética da criança no Ensino Fundamental

In the historical-cultural perspective, the drawing is processed by means of a shared and complex way, under diverse relations with the other and with the immersed signs of the culture. That is, something constituted by the social interactions and that can modify the structure of the psychological functions, therefore as socialized sign, propitiates the incorporation of the functions socially. In this way, the figuration carrier sensitive and established meanings historically disclosing the shared experiences and the ways of the subject to think and perceive the world. Such reflections gave shape to the main problem of this research: how to think over about the drawing at the school to incide in the reconstruction of the childs imaginative language? Under such perspective, this work deals with the interactions in the production process of the drawing of the children in a context of teach-Iearning of the elementary school having as goal to analyze the interactions established in the cIassroom in the process of production of the drawings; to propose situations of learnings that favor the advance graphical expression of the students; and to identify in the interactive games some relations between body expression and drawing. For its accomplishment, it was opted for the construction process based in the collaborative investigation by the fact to propitiate negotiations, sharing and confrontation of ideas, becoming possible a joint construction of the knowledge. For this research, the researcher and the collaborating teacher, as well as the involved children, become themselves into co-authors of the context studied. As locus of the research, it was chosen a first cycle class, with 30 students, from Municipal School Profª. Emília Ramos (Natal/RN - Brazil), whose election took in account the fact of this school to constitute in a promotional space of reflections and professional development of teachers in service and, at the same time, for presentinglimitations theoretic- methodological in the field of teaching for Arts. In the process of the research, it was perceived that the children with the support of the verbal language formulates meanings on the seen and imagined object, printing lines and forms that if overlap to the physiological aspects of the visual perception. That is, the drawing discloses a reality appraised, enriched for the picked up vision of the image, but the meanings established for the author, or observer who becomes it perceivable and identified. In the systemizing situations, it was observed that the teaching-Iearning process of the drawing, implies a co-construction between teachers and learners. And, moreover, the necessity to interlace emotion and cognition by means of plastic-corporal interactions that foment drawing experiences, whose process concurs for the imagenative reconstruct of the apprentices

COSTA REGO E O CURSO PIONEIRO DE JORNALISMO DA UNIVERSIDADE DO DISTRITO FEDERAL

A história da Universidade do Distrito Federal (UDF) perpassa por sua experiência singular na institucionalização do Ensino Superior no Brasil. Fruto de um movimento educacional liberal pelo saber desinteressado e comprometido apenas com a verdade, a universidade carrega a honra de ter instituído o primeiro curso de Jornalismo no país. Sistematizado pelo jornalista Pedro da Costa Rego, editor do diário carioca Correio da Manhã e reconhecido como um dos profissionais da Imprensa mais respeitados de sua época, o curso foi relegado ao esquecimento, após o fechamento da instituição em razão do Golpe de Getúlio Vargas, com o início do Estado Novo. Este trabalho visa resgatar a importância desse ensaio inédito do Jornalismo na universidade, desvendando as bases teóricas que forneceram subsídios a Costa Rego para sistematizar o curso e como sua trajetória profissional o credenciou para ser o Primeiro Catedrático em Jornalismo do Brasil. Um estudo histórico, que se utiliza da pesquisa documental e bibliográfica para preencher essa lacuna no processo comunicacional brasileiro.(AU)
