Dear living person

This chapter is written from the perspective of a recently deceased corpse. It examines the claims art makes to moving beyond boundaries and testing limits (of medium, discipline, and category) as a cliché of transcendence. This is described in relation to the operation of the false ‘master’ limit between the living and the dead, with reference to Reza Negarestani’s vivid reenactment of Etruscan torture, and contemporary performances of institutional critique: Fraser, Krebber and Carpenter.

Demand side management for the European Supergrid: occupancy variances of European single-person households

The prospect of a European Supergrid calls for research on aggregate electricity peak demand and Europe-wide Demand Side Management. No attempt has been made as yet to represent a time-related demand curve of residential electricity consumption at the European level. This article assesses how active occupancy levels of single-person households vary in single-person household in 15 European countries. It makes use of occupancy time-series data from the Harmonised European Time Use Survey database to build European occupancy curves; identify peak occupancy periods; construct time-related electricity demand curves for TV and video watching activities and assess occupancy variances of single-person households.

Parameterising ecological validity and integrating individual differences within second-person neuroscience

This commentary situates the second person account within a broader framework of ecological validity for experimental paradigms in social cognitive neuroscience. It then considers how individual differences at psychological and genetic levels can be integrated within the proposed framework.

Within-person analyses of situational interest and boredom: Interactions between task-specific perceptions and achievement goals

Despite the increasing number of studies examining the correlates of interest and boredom, surprisingly little research has focused on within-person fluctuations in these emotions, making it difficult to describe their situational nature. To address this gap in the literature, this study conducted repeated measurements (12 times) on a sample of 158 undergraduate students using a variety of self-report assessments, and examined the within-person relationships between task-specific perceptions (expectancy, utility, and difficulty) and interest and boredom. This study further explored the role of achievement goals in predicting between-person differences in these within-person relationships. Utilizing hierarchical-linear modeling, we found that, on average, a higher perception of both expectancy and utility, as well as a lower perception of difficulty, was associated with higher interest and lower boredom levels within individuals. Moreover, mastery-approach goals weakened the negative within-person relationship between difficulty and interest and the negative within-person relationship between utility and boredom. Mastery-avoidance and performance-avoidance goals strengthened the negative relationship between expectancy and boredom. These results suggest how educators can more effectively instruct students with different types of goals, minimizing boredom and maximizing interest and learning.

An enhanced fall detection system for elderly person monitoring using consumer home networks

Various fall-detection solutions have been previously proposed to create a reliable surveillance system for elderly people with high requirements on accuracy, sensitivity and specificity. In this paper, an enhanced fall detection system is proposed for elderly person monitoring that is based on smart sensors worn on the body and operating through consumer home networks. With treble thresholds, accidental falls can be detected in the home healthcare environment. By utilizing information gathered from an accelerometer, cardiotachometer and smart sensors, the impacts of falls can be logged and distinguished from normal daily activities. The proposed system has been deployed in a prototype system as detailed in this paper. From a test group of 30 healthy participants, it was found that the proposed fall detection system can achieve a high detection accuracy of 97.5%, while the sensitivity and specificity are 96.8% and 98.1% respectively. Therefore, this system can reliably be developed and deployed into a consumer product for use as an elderly person monitoring device with high accuracy and a low false positive rate.

The acquisition of person and number morphology within the verbal domain in Early Greek

The aim of this paper is to examine the acquisition pattern of person and number verb morphology within the generative framework and to compare the results of the analyses with previous research in Greek and other European languages. The study considers previous data on the acquisition of subject-verb agreement, and thereafter, examines the acquisition of person and number morphology in a new dataset of two monolingual Greek-speaking children. The analyses present quantitative data of accuracy of person and number marking, error data, and qualitative analyses addressing the productivity of person and number marking. The results suggest that person and number morphology is used correctly and productively from a very early age in Greek speaking children. The findings provide new insight into early Greek language acquisition and are also relevant for research in early development of languages with rich inflectional morphology.

Video stimuli reduce object-directed imitation accuracy: a novel two-person motion-tracking approach

Imitation is an important form of social behavior, and research has aimed to discover and explain the neural and kinematic aspects of imitation. However, much of this research has featured single participants imitating in response to pre-recorded video stimuli. This is in spite of findings that show reduced neural activation to video vs. real life movement stimuli, particularly in the motor cortex. We investigated the degree to which video stimuli may affect the imitation process using a novel motion tracking paradigm with high spatial and temporal resolution. We recorded 14 positions on the hands, arms, and heads of two individuals in an imitation experiment. One individual freely moved within given parameters (moving balls across a series of pegs) and a second participant imitated. This task was performed with either simple (one ball) or complex (three balls) movement difficulty, and either face-to-face or via a live video projection. After an exploratory analysis, three dependent variables were chosen for examination: 3D grip position, joint angles in the arm, and grip aperture. A cross-correlation and multivariate analysis revealed that object-directed imitation task accuracy (as represented by grip position) was reduced in video compared to face-to-face feedback, and in complex compared to simple difficulty. This was most prevalent in the left-right and forward-back motions, relevant to the imitator sitting face-to-face with the actor or with a live projected video of the same actor. The results suggest that for tasks which require object-directed imitation, video stimuli may not be an ecologically valid way to present task materials. However, no similar effects were found in the joint angle and grip aperture variables, suggesting that there are limits to the influence of video stimuli on imitation. The implications of these results are discussed with regards to previous findings, and with suggestions for future experimentation.

Bayesian inference for a skew-normal IRT model under the centred parameterization

Item response theory (IRT) comprises a set of statistical models which are useful in many fields, especially when there is interest in studying latent variables. These latent variables are directly considered in the Item Response Models (IRM) and they are usually called latent traits. A usual assumption for parameter estimation of the IRM, considering one group of examinees, is to assume that the latent traits are random variables which follow a standard normal distribution. However, many works suggest that this assumption does not apply in many cases. Furthermore, when this assumption does not hold, the parameter estimates tend to be biased and misleading inference can be obtained. Therefore, it is important to model the distribution of the latent traits properly. In this paper we present an alternative latent traits modeling based on the so-called skew-normal distribution; see Genton (2004). We used the centred parameterization, which was proposed by Azzalini (1985). This approach ensures the model identifiability as pointed out by Azevedo et al. (2009b). Also, a Metropolis Hastings within Gibbs sampling (MHWGS) algorithm was built for parameter estimation by using an augmented data approach. A simulation study was performed in order to assess the parameter recovery in the proposed model and the estimation method, and the effect of the asymmetry level of the latent traits distribution on the parameter estimation. Also, a comparison of our approach with other estimation methods (which consider the assumption of symmetric normality for the latent traits distribution) was considered. The results indicated that our proposed algorithm recovers properly all parameters. Specifically, the greater the asymmetry level, the better the performance of our approach compared with other approaches, mainly in the presence of small sample sizes (number of examinees). Furthermore, we analyzed a real data set which presents indication of asymmetry concerning the latent traits distribution. The results obtained by using our approach confirmed the presence of strong negative asymmetry of the latent traits distribution. (C) 2010 Elsevier B.V. All rights reserved.

Prosodic Morphology : Gender in Arabic Perfect Active and Passive 3rd Person Singular Verbs

Prosodic /template Morphology, that "draws heavily on the theoretical apparatus and formalisms of the generative phonology model known as autosegmental phonology" (Katamba, F. 1993: 154), is the best analysis that can handle Arabic morphology. Verbs in Arabic are represented on three independent tiers: root tier, the skeletal tier and the vocalic melody tier (Katamba, F. 1993). Vowel morphemes, which are represented by diacritics, are inserted within the consonant morphemes, which are represented by primary symbols, to form words. The morpheme tier hypothesis paves the way to understand the nonconcatenative Arabic morphology. This paper analyzes gender in perfect active and passive 3rd person singular verbs on the basis of PM. The focus of the analysis shall be drawn heavily on the most common Arabic verbs; triconsonantal verbs, with brief introduction of the less common verbs; quadriconsonantal perfect active and passive masculine and feminine 3rd person singular verbs. I shall, too, cast the light on some vowel changes that some verbs undergo when voice changes.

Att vara familjemedlem till en person med schizofreni : En litteraturstudie utifrån familjens perspektiv

Syftet var att utifrån familjemedlemmars perspektiv, beskriva upplevelser och hantering av att ha en familjemedlem med diagnosen schizofreni. Metoden tillämpades till vald design, där material till litteraturstudien söktes via databaserna Cinahl, MEDLINE och PsycINFO. Studiens underlag bestod av 13 artiklar av både kvalitativ och kombinerad ansats, som efter granskning och analys valdes till resultat. Resultatet presenterades genom två kategorier följt av fem subkategorier och visade att sjukdomens medförda beteendeförändring upplevdes som förlust av den person den drabbade en gång var. Känslor som förvirring och förtvivlan upplevdes till följd av den drabbades främmande personlighet. Situationen uppgavs som känslomässigt komplicerad, med svårighet att göra tillståndet begripligt och hanterbart. I takt med sjukdomens utveckling, upplevdes den drabbades förmåga till självständighet minska. Ansvaret att stötta den drabbade, föll på familjemedlemmarna som uppgav svårigheter med att uppnå en tillfredställande balans i vardagen. Känslor som skuld, hopplöshet och enorm belastning upplevdes till följd av ansvaret att försöka tillmötesgå den drabbades och övriga familjemedlemmars behov, samtidigt som de försökte förhindra brutna band inom familjen. Sjukdomen upplevdes påverka hela familjen och inte enbart den drabbade. För att kunna leva med den omfattande förändring som sjukdomen medförde, uppgav familjemedlemmarna vikten och behovet av stöd både inom och utanför familjen.

Anhörigas upplevelser i samband med vård av en äldre person i hemmet : En litteraturöversikt

SAMMANFATTNINGSyftet: Syftet med denna systematiska litteraturstudie var att studera hur anhöriga till äldre personer upplevde sin situation i i samband med att de vårdade sina äldre hemma, hur de hanterade sin situation, samt vilka strategier de använde sig av för att hantera sin roll som anhörigvårdare. Metod: Databaserna Cinahl och Medline användes i sökningarna efter relevanta artiklar. Sökord som användes var relative and older people and home care, home health care and family caregiver elderly people, family caregivers and care givers of aging people, elderly people and family care givers of aging people, family care givers of older people, family caregivers and frail elderly, family caregiver and older people and home care, home care older people and family caregivers older people, family caregivers older people. Efter genomläsning bedömdes 16 artiklar vara användbara i resultatet. Dessa kom från vetenskapliga tidskrifter och artiklarna innehöll både kvalitativa studier som kvantitativa studier. Resultat: De flesta anhörigvårdare var kvinnor, de kunde uppleva en högre belastning än män. De anhöriga påverkades både mentalt, fysiskt och emotionellt. De kände sig bundna men kunde även känna ett välbefinnande i vården av den äldre personen. Anhöriga upplevde sin roll som anhörigvårdare till äldre personer i hemmen som att de var delaktiga i omsorgen genom praktiskt som känslomässigt stöd. Deras situation hade även inverkan på deras upplevelse av stress och hur de hanterade situationen. En del äldre anhörigvårdare var själva äldre och i behov av hjälp. Konsekvenserna av deras reaktioner/upplevelser beskrevs som både subjektiv och objektiv belastning. Samt att de även var mindre benägna att söka stöd i form av avlastning för sina äldre personer. Slutsats: Rollen som anhörigvårdare till äldre personer som vårdas i hemmen innebar förändringar i anhörigas livssituation, de fick ta ett stort ansvar för den äldre personen. De upplevde stora påfrestningar både känslomässigt som praktiskt, många kände sig ensamma utan stöd, andra hade olika sätt att hantera sin situation. Äldre anhörigvårdare var mer utsatta för belastning av olika skäl när de vårdade äldre personer i hemmet, dels var de själva äldre samt att de själva kunde vara i behov av hjälp för sina hälsoproblem. Kvinnorna var den grupp anhörigvårdare som upplevde störst belastning i vården av äldre personer i hemmet. När det gällde att söka hjälp och stöd såg det olika ut bland anhörigvårdarna, trots att kvinnorna upplevde störst belastning var de minst benägna att söka hjälp.

Animalism and Person as a Basic Sort

In this paper Animalism is analysed. It will be argued that Animalism is correct in claiming (i) that being of a certain sort of animal S is a fundamental individuative substance sortal concept (animal of the species Homo Sapiens), (ii) that this implies that Animalism is correct in claiming that persons such as us are, by necessity, human beings, (iii) that remaining the same animal is a necessary condition for our identity over time. Contrary to Animalism it will be argued that this does not imply that person should be understood as a phased sortal concept. It will be argued that Animalism rests upon a prior conception of person, and that this implies that person must be understood as a basic substance sortal concept through which we have to individuate ourselves and others. It is further argued that this, together with the insights of Animalism, implies that persons, by necessity, are beings of a biological nature.
