Cyberspace Odyssey: Towards a Virtual Ontology and Anthropology

Throughout the late 1990s, ‘cyberspace’ became a key point of interest in sociology, media theory and certain strands of anthropology. There were fierce debates over what would become of our identities, our friendships, our sense of place, and even our bodies in the then dazzling new world of online communication, networked relationships and virtual reality. Such debates were accompanied by a renewed interest in questions of being, or ontology, and by concerns over what it would mean to be human in an age of seemingly ‘intelligent’ media. Cyberspace Odyssey returns to many of these themes. It centres on the following questions: first, ‘how to understand cyberspace’; second, ‘in what way does this new matrix of space-time affect our understanding of the world and ourselves? ’ and third, ‘how far will our odyssey through cyberspace actually change our world and ourselves? ’ (p. 15). Jos de Mul addresses these questions by exploring a wide-range of topics, including: the digitalization of culture (Chapter 6); interactive cinema and digital photography (Chapters 5 and 8); and identity construction in the age of the Internet (Chapter 10), to name but a few. The problem is that many of these topics, including the concern with ‘cyberspace’, now feel a little time-worn. Many things have changed since the 1990s, particularly following the emergence of mobile computational devices and social networking sites that today are almost ubiquitous in everyday life. Such changes are registered, but are never dealt with in detail in this book. Chapter 10, for example, refers to the advent of Web 2.0 and to applications such as Skype and YouTube, but only in brief, and as a consequence the ontological significance of such developments is left largely unexplored. Instead, the author makes a number of statements that may once have been profound, but are now pretty much self-evident. For example: ‘The World Wide Web differs from older multimedia like television or film in that all applied media share a digital code’ (p. 183). Or: ‘Webpages not seldom contain elements that previously belonged mainly to the personal sphere, such as diary-like notes, travelogues, photos from private life, etc.’ (p. 186). Coupled with this, there are important scholarly writings on being and ontology in the digital age that do not feature in this book.
Examining the effect of negative Turkish stereotypes on evaluative workplace outcomes in Germany

Purpose – The purpose of this paper is to assess the impact that negative stereotypes have on suitability ratings of Turkish applicants in a simulated hiring scenario.Design/methodology/approach – This paper utilizes a within subjects experimental design in which participants assessed four fictitious male candidates ostensibly applying for a managerial position; two of German descent, two of Turkish descent. Participants also completed a newly developed measure designed to assess the degree to which people endorse negative stereotypes of Turkish males in managerial positions.Findings – The results suggest that the endorsement of a negative Turkish stereotype significantly predicts suitability ratings for highly qualified Turkish candidates.Research limitations/implications – Stereotype endorsement should be considered when investigating, and making claims about the impact of demographic characteristics on evaluative workplace outcomes.Practical implications – In the service of diversity, organizations sho.
A hybrid adaptive Neural-Fuzzy tuned P.I. controller based Unidirectional Boost P.F.C. converter feeds B.L.D.C. drive

The demand for solid state A.C. -D.C. converters to enhance power quality in the expression of P.F. C. (Power Factor Correction) impels the proposal of miscellaneous topologies. This paper presents a hybrid Neural-Fuzzy Controller (N.F.C.) tuned P.I. controller based Unidirectional Boost P.F. C. converter not only for regulating the drawn current, minimizing harmonics pollutions (that deteriorating the system power quality) and enhancing the circuit efficiency but also for B.L. D.C. (Brush Less D.C.) machine speed controlling. The paper first presents a mathematical model and P.F. C. circuit; besides it depicts the way of hybrid controlling system evolves the controlling of drives performance at both transient and steady state conditions. It is important to be concerned that an integral robust S.S. E.E. (Steady State Error Eliminator) is paralleled to the system developing the controlling process wholly. Minimizing A.C. supply current distortion as close as to unity P.F. over a wide range of rotational speed is one of the advantages of this enhanced system. The presented modeled system contains Hybrid Neural-Fuzzy Controlling units, P.F. C. unit, unidirectional Boost Converter and B.L. D.C. machine; that simulated MATLAB model is proposed and discussed in details. Simulation results significantly depict the impressiveness of the proposed controlling system in T.H. D. reduction.
Maximal Effective Diffusivity for Time-Periodic Incompressible Fluid Flows

In this paper we establish conditions for the maximal, $Pe^2 $, behavior of the effective diffusivity in time-periodic incompressible velocity fields for both the $Pe \to \infty $ and $Pe \to 0$ limits. Using ergodic theory, these conditions can be interpreted in terms of the Lagrangian time averages of the velocity. We reinterpret the maximal effective diffusivity conditions in terms of a Poincare map of the velocity field. The connection between the $Pe^2 $ asymptotic behavior of the effective diffusivity and $t^2 $ asymptotic dispersion of a nondiffusive tracer is established. Several examples are analyzed: we relate the existence of accelerator modes in a flow with $Pe^2 $ effective diffusivity and show how maximal effective diffusivity can appear as a result of a time-dependent perturbation of a steady cellular velocity field. Also, three-dimensional, symmetric, time-dependent duct velocity fields are analyzed, and the mechanism for an effective diffusivity with Peclet number dependence other than $P.
Agency of labour in a flexible pan-European labour market : a qualitative study of migrant practices and trade union strategies in the Netherlands

In Europa is de grensoverschrijdende arbeidsmobiliteit toegenomen door het vrije verkeer van personen, diensten en vestiging en een steeds flexibelere arbeidsmarkt. Vanwege de uitbreiding van de Europese Unie zijn ook in Nederland veel arbeidsmigranten uit Oost-Europa werkzaam in sectoren als de bouw, agrarische sector, en de vleesverwerkende industrie. Ze worden vaak door bedrijven op tijdelijke basis te werk gesteld onder oneigenlijke constructies, gebruikmakend van verschillen in wet- en regelgeving tussen landen. Regelmatig is dan ook uit nieuwsberichten op te maken dat de arbeidsvoorwaarden van Europese arbeidsmigranten niet overeenstemmen met Nederlandse standaarden. Waar bedrijven grensoverschrijdend werken, opereren vakbonden en arbeidsinspectie voornamelijk nationaal, waardoor handhaving tekort schiet. Hoewel er dus geregeld bericht wordt over deze groep migranten, is er weinig onderzoek gedaan waarin daadwerkelijk met hen wordt gesproken. Om te onderzoeken hoe deze migranten omgaan met de competitieve dynamiek van de Europese arbeidsmarkt, heeft Lisa Berntsen met ongeveer 90 arbeidsmigranten gesproken over hun ervaringen in Nederland. Ze onderzocht hoe migranten individueel, gezamenlijk en georganiseerd - via de Nederlandse vakbond - handelen wanneer zij geconfronteerd worden met ondermaatse arbeidsomstandigheden. Migranten blijken veelal op kleinschalige, onzichtbare wijzen te opereren, in plaats van collectief via vakbonden. Dit heeft weinig tot geen effect op het verbeteren van de werkomstandigheden. Op grotere schaal draagt deze handelswijze mogelijk zelfs bij aan het versterken van de competitieve Europese marktwerking en het in stand houden van ongelijke arbeidsverhoudingen. Maar, zo toont Berntsen aan, onder bepaalde omstandigheden zijn deze migranten wel bereid zich te organiseren via een vakbond.
A mobile phone-based physical-social location proof system for mobile social network service

Location-related mobile social network services are popular nowadays, and their methods to obtain end users' location information are based on people's self-report location claims, using mobile devices to check positions and send them back to the service providers. However, this mechanism has a serious vulnerability that makes malicious users be able to access restricted resource by transmitting fake locations. Both academic and industrial researchers are recently aware of this problem's importance since the commercialized trend of location-related mobile social network services. To address this issue, we propose mobile phone-based physical-social location, a mobile phone-based location proof system to verify users' location claims and defend various fake location information. Our core idea is that a user's location claim can be proved by a set of selective physical encountered people serving as "witnesses" who are co-located with him/her in that area. The system is composed of proof generation and verification. In the proof generation phase, we leverage a certain number of co-located people to generate certificates as location proofs during their encounters via bluetooth interface. In the verification phase, we propose an efficient verification scheme to make our system accurate and adaptive. We have implemented the MPSL system using real world Nokia N82 Nokia, Espoo, Finland phones. Our experimental results show that our mobile phone-based system can achieve high verification accuracy and good performance. Copyright © 2014 John Wiley & Sons, Ltd.
THE RELATIONSHIP BETWEEN SCHMIDT‐LANTERMANN INCISURES AND MYELIN SEGMENTATION DURING WALLERIAN DEGENERATION *

Although incisures in myelin sheaths of both living and fixed peripheral nerve fibers were described by Schmidt and Lantermann more than 80 years ago, neither their origin and function in normal nerves nor their role in peripheral nerve demyelination are completely understood. At the resolution of the light microscope, these clefts in myelin appear as gaps of varying width in unfixed nerves as well as in those fixed or stained by standard methods for the demonstration of myelin sheaths. Surveys of longitudinal sections have shown that they are more numerous in larger myelinated fibers’, and that, in a given fiber, they are infrequent adjacent to nodes of Ranvier. ‘ Similar incisures with the same distribution have also been observed in myelin sheaths which have been formed and maintained in ~ i t r o . ~ The apparent discontinuity of the myelin sheath observed by light microscopy suggested that the Schmidt-Lantermann clefts might serve as channels for ionic flow to the axon surface. Although the demonstration of the delicate spiral apparatus of Golgi-Rezzonico in incisures by silver methods, and the absence of supravital staining within the clefts and adjacent axon were not consistent with this functional interpretation, further elucidation of the morphology of these clefts in myelin required the higher resolving power of electron microscopy. In 1958, an ultrastructural study of Schmidt-Lantermann incisures by Robertson showed that the concentric membrane layers making up the myelin sheath traversed these clefts and were separated by pockets of Schwann cell cytoplasm. * These observations indicated that incisures did not function as significant pathways for current flow during impulse transmission. Because of the varied appearance of incisures, Robertson suggested that they represented “stages in a dynamic process whereby the myelin lamellae are continually parting and coming together during life in response to physiological stresses and strains. ” Our observations have been consistent with this interpretation and suggested that accentuation of this dynamic process of lamellar separation by Schwann cell cytoplasm in the form of incisures might precede and ultimately produce myelin segmentation during the early stages of Wallerian degeneration. Although the occurrence of myelin segmentation at incisures is a well-known feature of Wallerian degenerati~n,~ the number and distribution of Schmidt-Lantermann clefts prior to myelin breakdown have not been described previously and are included in this report.
Generating Unit Tests with Structured System Interactions

There is a large body of work in the literature about automatic unit tests generation, and many successful results have been reported so far. However, current approaches target library classes, but not full applications. A major obstacle for testing full applications is that they interact with the environment. For example, they access files on the hard drive or establish connections to remote servers. Thoroughly testing such applications requires tests that completely control the interactions between the application and its environment. Recent techniques based on mocking enable the generation of tests which include environment interactions, however, generating the right type of interactions is still an open problem. In this paper, we describe a novel approach which addresses this problem by enhancing search-based testing with complex test data generation. Experiments on an artificial system show that the proposed approach can generate effective unit tests. Compared with current techniques based on mocking, we generate more robust unit tests which achieve higher coverage and are, arguably, easier to read and understand.
Face and Word Recognition Can Be Selectively Affected by Brain Injury or Developmental Disorders

Face and word recognition have traditionally been thought to rely on highly specialised and relatively independent cognitive processes. Some of the strongest evidence for this has come from patients with seemingly category-specific visual perceptual deficits such as pure prosopagnosia, a selective face recognition deficit, and pure alexia, a selective word recognition deficit. Together, the patterns of impaired reading with preserved face recognition and impaired face recognition with preserved reading constitute a double dissociation. The existence of these selective deficits has been questioned over the past decade. It has been suggested that studies describing patients with these pure deficits have failed to measure the supposedly preserved functions using sensitive enough measures, and that if tested using sensitive measurements, all patients with deficits in one visual category would also have deficits in the other. The implications of this would be immense, with most textbooks in cognitive neuropsychology requiring drastic revisions. In order to evaluate the evidence for dissociations, we review studies that specifically investigate whether face or word recognition can be selectively affected by acquired brain injury or developmental disorders. We only include studies published since 2004, as comprehensive reviews of earlier studies are available. Most of the studies assess the supposedly preserved functions using sensitive measurements. We found convincing evidence that reading can be preserved in acquired and developmental prosopagnosia and also evidence (though weaker) that face recognition can be preserved in acquired or developmental dyslexia, suggesting that face and word recognition are at least in part supported by independent processes.
Gender-related differences in the characteristics of problem gamblers using a gambling helpline.

OBJECTIVE The characteristics of male and female gamblers utilizing a gambling helpline were examined to identify gender-related differences. METHOD The authors performed logistic regression analyses on data obtained in 1998-1999 from callers to a gambling helpline serving southern New England. RESULTS Of the 562 phone calls used in the analyses, 349 (62.1%) were from male callers and 213 (37.9%) from female callers. Gender-related differences were observed in reported patterns of gambling, gambling-related problems, borrowing and indebtedness, legal problems, suicidality, and treatment for mental health and gambling problems. Male gamblers were more likely than female gamblers to report problems with strategic or "face-to-face" forms of gambling, e.g., blackjack or poker. Female gamblers were more likely to report problems with nonstrategic, less interpersonally interactive forms of gambling, e.g., slot machines or bingo. Female gamblers were more likely to report receiving nongambling-related mental health treatment. Male gamblers were more likely to report a drug problem or an arrest related to gambling. High rates of debt and psychiatric symptoms related to gambling, including anxiety and depression, were observed in both groups. CONCLUSIONS Individuals with gambling disorders have gender-related differences in underlying motivations to gamble and in problems generated by excessive gambling. Different strategies may be necessary to maximize treatment efficacy for men and for women with gambling problems.
Statistical models for text query-based image retrieval

Image indexing and retrieval has been an active research area for more than one decade. Although many accomplishments have been made in this domain, it is still a challenging problem and far from being solved. Traditional content-based approaches make use of queries based on image examples or image attributes like color and texture, and images are retrieved according to the similarity of each target image with the query image. However, image query based retrieval systems do not really capture the semantics or meanings of images well. Furthermore, image queries are difficult and inconvenient to form for most users. To capture the semantics of images, libraries and other organizations have manually annotated each image with keywords and captions, and then search on those annotations using text retrieval engines. The disadvantage of this approach is the huge cost of annotating large number of images and the inconsistency of annotations by different people. In this work, we focus on general image and historical handwritten document retrieval based on textual queries. We explore statistical model based techniques that allow us to retrieve general images and historical handwritten document images with text queries. These techniques are (i) image retrieval based on automatic annotation, (ii) direct retrieval based on computing the posterior of an image given a text query, and (iii) handwritten document image recognition. We compare the performance of these approaches on several general image and historical handwritten document collections. The main contributions of this work include (i) two probabilistic generative models for annotation-based retrieval, (ii) a direct retrieval model for general images, and (iii) a thorough investigation of machine learning models for handwritten document recognition. Our experimental results and retrieval systems show that our proposed approaches may be applied to practical textual query based retrieval systems on large image data sets.
SEMI-PARAMETRIC ESTIMATES UNDER BIASED SAMPLING

In observational studies subjects may self select, thereby creating a biased sample. Such problems arise frequently, for example, in astronomical, biomedical, animal, and oil studies, survey sampling and econometrics. For a typical subject, let Y denote the value of interest and suppose that Y has an unknown density function f . Further, let w(y) denote the probability that the subject includes itself in the study given Y = y. Then the conditional density of Y given that it is observed is f ∗ (y )= w(y)f (y)/κ ,w hereκ is a normalizing constant. The problem of estimating w and f from a biased sample X1 ,. ,X n independently from f ∗ is considered when f is known to belong to a parametric family, say f = fθ ,w here θ is a vector of unknown parameters, and w is assumed to be non-decreasing. An algorithm for computing the maximum likelihood estimator of (w, θ) is developed, and consistency is established. Simulations are used to show that our method is feasible with moderate sample size, and applications to animal and oil data are given.
