D3.3 : Game Experience Questionnaire:development of a self-report measure to assess the psychological impact of digital games

The current report describes the development of the Game Experience Questionnaire, a self-report measure that aims to comprehensively and reliably characterise the multifaceted experience of playing digital games. Its development and evaluation precede the testing of the other measures of game experience targeted in the FUGA project, as it will be employed for evaluating validity of these measures. The theoretical work performed by all partners in the FUGA project (Deliverable 2.1) provided a firm and broad basis for the development of the scale. In addition, relevant scientific literature was reviewed for any conceptualisations that might complement this work and for existing scales that might serve as a starting point or inspiration for item formulation. Furthermore, empirical data was gathered during focus group interviews with different types of gamers. These interviews served as a test for comparing scientific conceptualisations and lay descriptions of first-hand experiences. They were also used as a reference guide on choice of wording in the item formulation phase. The Game experience questionnaire is developed with a modular structure, consisting of: 1. The core questionnaire (GEQ). This is the heart of the Game Experience Questionnaire, probing multiple components of players’experience while gaming. 2. The post-game questionnaire (PGQ), probing gamers’experience after the gaming session and any after effects. 3. The social presence module (SPGQ), probing gamers’experience of and involvement with their co-player(s). These three lists are to be administered after the gaming session has ended. Additionally, a short in- game version of the GEQ was developed, the iGEQ, for probing in-game experience multiple times during a gaming session. A large scale survey was performed to test the long list (>100 items) and explore the factor structure of the questionnaires. Factor analyses provided a structure for the scale that made good sense in the light of theoretical considerations, with subscales that were all easy to interpret. Subsequent reliability tests resulted in the construction of robust subscales with satisfactory to high internal consistencies. Additional explorations were subsequently performed to check sensitivity and validity of the developed measures. Statistical analyses firmly demonstrated that the GEQ and additional modules were sensitive enough to pick up differences between gamers, game types, play characteristics, and social context of play. The findings already provide new insights to scholars in the field. The Game Experience Questionnaire is now ready to be translated and used in FUGA experimentations.
ACCURACY EVALUATION OF GROUND POINTS FROM IKONOS HIGH-RESOLUTION SATELLITE IMAGERY

To evaluate the geometric accuracy of ground points from integrated Global Positioning System, inertial navigation system, and high-resolution linear array CCD sensor data, this paper presents a mathematical model of the bundle adjustment and the experimental results on the attainable accuracy of ground points vs. number and distribution of ground control points (GCPs), vs. the image measurement error of GCPs and checkpoints, and vs. the order of the polynomial fit to the orbital path. A geodetic control network established in Madison County (Ohio), used to test the 3-D accuracy of the simulated new generation IKONOS high-resolution satellite imagery, is introduced. Based on the airborne High Resolution Stereo Camera system and simulated IKONOS imagery, various experimental schemes involving geometric strength with various configurations of stereo models, the influence of the number and distribution of GCPs, and the influence of the image measurement errors of GCPs and checkpoints were performed. Some recommendations and suggestions to improve the geometric accuracy of ground points are provided.

The Long Arm of Poverty: Extended and Relational Geographies of Child Victimization and Neighborhood Violence Exposures

Current models of neighborhood effects on victimization predominantly assume that residential neighborhoods function independent of their surroundings. Yet, a surprising proportion of violence occurs outside of victims’ residential neighborhoods. The current study extends on recent advances in spatial dynamics and neighborhood effects to explore the importance of different geographic scales and relational exposures to poverty for child violent victimization. We examine longitudinal data on over 4400 low-income children from high poverty neighborhoods in five cities, who participated in the Moving to Opportunity randomized intervention. The results suggest that surrounding poverty matters for child victimization beyond the effect of residential poverty. Moreover, moving farther from extreme poverty also seems to buffer against victimization and to amplify the benefits of moving to improved extended (residential and surrounding) neighborhoods. All the children in the study, but especially boys older than 10 years of age, seemed to be affected by the long arm of poverty.
ntercomparison and quality assessment of MERIS , MODIS and SEVIRI FAPAR roducts over the Iberian Peninsula

The fraction of absorbed photosynthetically active radiation (FAPAR) is a key variable in productivity and carbon cycle models. The variety of available FAPAR satellite products from different space agencies leads to the necessity of assessing the existing differences between them before using into models. Discrepancies of four FAPAR products derived from MODIS, SEVIRI and MERIS (TOAVEG and MGVI algorithms), covering the Iberian Peninsula from July 2006 to June 2007 are here analyzed. The assessment is based on an intercomparison involving the spatial and temporal consistency between products and a statistical analysis across land cover types. In general, significant differences are found over the Iberian Peninsula concentrated on the temporal variation and absolute values. The MODIS and MERIS/MGVI ross primary production FAPAR products clearly show the highest and lowest absolute values, respectively, along with the lowest intra-annual variation. When considering individual land cover types, the largest FAPAR disagreements among the analyzed products were found between MODIS-MERI/MGVI and MERIS/TOAVEG-MERIS/MGVI over broadleaf and needleaf forests, with discrepancies quantified by RMSE higher than 0.30 and absolute bias higher than 0.25. These discrepancies can lead to relative gross primary production differences up
‘A Secret Punishment’: The Misuse of Segregation in Immigration Detention

Segregation – a secret punishment draws on case studies from Medical Justice’s work in IRCs to shed light on the solitary and secretive world of segregation. Segregation is one of the most severe and dangerous sanctions that can be imposed on detainees. The devastating impact of segregation on mental and physical health is widely recognised. Still there is little regulation or scrutiny of the use of segregation in Immigration Removal Centres (IRCs). Despite repeated damning critique from independent inspectors the over use and misuse of segregation continues in IRCs across the UK. Lack of central monitoring means there is little reliable data and significant discrepancy in rates reported, with an estimated 1200 – 4800 detainees segregated annually. This research identifies worrying trends such as prolonged segregation, the use of segregation as punishment, and segregation of the mentally ill or those at risk of self-harm. Some detainees are inappropriately segregated for months and even years, with one detainee being segregated more or less continuously for 22 months. One detainee was only removed to psychiatric hospital following 80 days in segregation whilst another was segregated more than 8 times during her 800 days in detention. Since the completion of the research the High Court has ruled that by treating a detainee as someone who was showing disruptive behaviour rather than mental illness and placing her in segregation, sometimes with force, this constituted a breach of her rights under Article 3 of the European Human Rights Convention.
The role of astrocytes in response to stimulation with the microbial endotoxin lipopolysaccharide

Though the cause of Parkinson’s disease (PD) remains unknown, many suspect its etiology includes both genetic mutations and exposures to environmental factors (e.g., microbial infections, heavy metals, pesticides, air pollution). This work attempted to understand the immunological roles of astrocytes and microglia, two brain cell types with innate immune properties, when exposed to the Gram-negative bacterial endotoxin lipopolysaccharide (LPS) in a mouse model of PD. This study found the immunoreactivity of astrocytes to LPS was attributed to the presence of microglia in ‘enriched’ astrocyte cultures. Reconstituting microglia back into a novel highly-enriched astrocyte culture (with <0.001% microglia) showed less than 0.5-1% microglia can account for the erroneous detection of proinflammatory factors by LPS-treated ‘enriched’ astrocytes. LPS was found to activate astrocytes via TNF-α produced by microglia, stimulating cytotoxic and neurotrophic factors release. Nonetheless, activated astrocytes protected neurons from microglial-derived bystander damage in this neuroinflammation-induced model of PD.
Ionospheric Electron Density Perturbations Driven by Seismic Tsunami-Excited Gravity Waves: Effect of Dynamo Electric Field

The effect of an ionospheric dynamo electric field on the electron density and total electron content (TEC) perturbations in the F layer (150–600 km altitudes) is investigated at two arbitrarily selected locations (noted as 29° N and 60° N in latitudes) in the presence of seismic tsunami-excited gravity waves propagating in a stratified, nondissipative atmosphere where vertical gradients of atmospheric properties are taken into consideration. Generalized ion momentum and continuity equations are solved, followed by an analysis of the dynamo electric field (E). The E -strength is within several mV/m, determined by the zonal neutral wind and meridional geomagnetic field. It is found that, at the mid-latitude location, n0 e is dominated by the atmospheric meridional wind when E = 0, while it is determined by the zonal wind when E ≠ 0. The perturbed TEC over its unperturbed magnitude lies in around 10% at all altitudes for E = 0, while it keeps the same percentage at most altitudes for E ≠ 0, except a jump to >25% in the F2-peak layer (300–340 km in height). By contrast, at the low-latitude location, the TEC jump is eliminated by the locally enhanced background electron density.
Antigen Recognition By Autoreactive Cd4+ Thymocytes Drives Homeostasis Of The Thymic Medulla

The thymic medulla is dedicated for purging the T-cell receptor (TCR) repertoire of self-reactive specificities. Medullary thymic epithelial cells (mTECs) play a pivotal role in this process because they express numerous peripheral tissue-restricted self-antigens. Although it is well known that medulla formation depends on the development of single-positive (SP) thymocytes, the mechanisms underlying this requirement are incompletely understood. We demonstrate here that conventional SP CD4+ thymocytes bearing autoreactive TCRs drive a homeostatic process that fine-tunes medullary plasticity in adult mice by governing the expansion and patterning of the medulla. This process exhibits strict dependence on TCR-reactivity with self-antigens expressed by mTECs, as well as engagement of the CD28-CD80/CD86 costimulatory axis. These interactions induce the expression of lymphotoxin α in autoreactive CD4+ thymocytes and RANK in mTECs. Lymphotoxin in turn drives mTEC development in synergy with RANKL and CD40L. Our results show that Ag-dependent interactions between autoreactive CD4+ thymocytes and mTECs fine-tune homeostasis of the medulla by completing the signaling axes implicated in mTEC expansion and medullary organization.
Clinic Predictive Factors for Insufficient Myocardial Reperfusion in ST-Segment Elevation Myocardial Infarction Patients Treated with Selective Aspiration Thrombectomy during Primary Percutaneous Coronary Intervention

Background. Insufficient data are available on the potential benefit of selective aspiration and clinical predictors for no-reflow in STEMI patients undergoing primary percutaneous coronary intervention (PPCI) adjunct with aspiration thrombectomy. Objective. The aim of our study was to investigate clinical predictors for insufficient reperfusion in patients with high thrombus burden treated with PPCI and manual aspiration thrombectomy. Methods. From January 2011 till December 2015, 277 STEMI patients undergoing manual aspiration thrombectomy and PPCI were selected and 202 patients with a Thrombolysis in Myocardial Infarction (TIMI) thrombus grade 4~5 were eventually involved in our study. According to a cTFC value, patients were divided into Group I (cTFC > 40), namely, insufficient reperfusion group; Group II (cTFC ≤ 40), namely, sufficient reperfusion group. Results. Univariate analysis showed that hypertension, multivessel disease, time from symptom to PCI (≧4.8 hours), and postaspiration cTFC > 40 were negative predictors for insufficient reperfusion. After multivariate adjustment, age ≧ 60 years, hypertension, time from symptom to PCI (≧4.8 hours), and postaspiration cTFC > 40 were independently associated with insufficient reperfusion in STEMI patients treated with manual aspiration thrombectomy. Upfront intracoronary GP IIb/IIIa inhibitor (Tirofiban) was positively associated with improved myocardial reperfusion. Conclusion. Fully identifying risk factors will help to improve the effectiveness of selective thrombus aspiration.
k‐t FOCUSS: A general compressed sensing framework for high resolution dynamic MRI

A model‐based dynamic MRI called k‐t BLAST/SENSE has drawn significant attention from the MR imaging community because of its improved spatio‐temporal resolution. Recently, we showed that the k‐t BLAST/SENSE corresponds to the special case of a new dynamic MRI algorithm called k‐t FOCUSS that is optimal from a compressed sensing perspective. The main contribution of this article is an extension of k‐t FOCUSS to a more general framework with prediction and residual encoding, where the prediction provides an initial estimate and the residual encoding takes care of the remaining residual signals. Two prediction methods, RIGR and motion estimation/compensation scheme, are proposed, which significantly sparsify the residual signals. Then, using a more sophisticated random sampling pattern and optimized temporal transform, the residual signal can be effectively estimated from a very small number of k‐t samples. Experimental results show that excellent reconstruction can be achieved even from severely limited k‐t samples without aliasing artifacts. Magn Reson Med 61:103–116, 2009. © 2008 Wiley‐Liss, Inc.
Differential Localization of δ Glutamate Receptors in the Rat Cerebellum: Coexpression with AMPA Receptors in Parallel Fiber–Spine Synapses and Absence from Climbing Fiber–Spine Synapses

The δ2 glutamate receptors are prominently expressed in Purkinje cells and are thought to play a key role in the induction of cerebellar long-term depression. The synaptic and subsynaptic localization of δ receptors in rat cerebellar cortex was investigated with sensitive and high-resolution immunogold procedures. After postembedding incubation with an antibody raised to a C-terminal peptide of δ2, high gold particle densities occurred in all parallel fiber synapses with Purkinje cell dendritic spines, whereas other synapses were consistently devoid of labeling. Among the types of immunonegative synapse were climbing fiber synapses with spines and parallel fiber synapses with dendritic stems of interneurons. At the parallel fiber–spine synapse, gold particles signaling δ receptors were restricted to the postsynaptic specialization. By the use of double labeling with two different gold particle sizes, it was shown that δ and AMPA GluR2/3 receptors were colocalized along the entire extent of the postsynaptic specialization without forming separate domains. The distribution of gold particles representing δ receptors was consistent with a cytoplasmic localization of the C terminus and an absence of a significant presynaptic pool of receptor molecules. The present data suggest that the δ2 receptors are targeted selectively to a subset of Purkinje cell spines and that they are coexpressed with ionotropic receptors in the postsynaptic specialization. This arrangement could allow for a direct interaction between the two classes of receptor.
Agile Processes and Methodologies: A Conceptual Study

This paper deals with the comparative study of agile processes. The paper will serve as guide to other software development process models. Agile processes have important applications in the areas of software project management, software schedule management, etc. In particular the aim of agile processes is to satisfy the customer, faster development times with lower defects rate. This paper compares the agile processes with other software development life cycle models. Agile processes are not always advantageous, they have some drawbacks as well; the advantages and disadvantages of agile processes are also discussed in this paper.
Laboratory and Field-based Assessment of Maximal Aerobic and Anaerobic Power in Professional Tennis Players

The purposes of this study were to determine the relationship between laboratory and field aerobic and anaerobic tests performances in professional tennis players. Fourteen professional tennis players (age 23.0 ± 1.9 years; height 178.9 ± 3.5 cm; weight 73.9 ± 7.6 kg; training experience 7.1 ± 1.1 years) participated in this study voluntarily. A portable gas-analysis system was used during the laboratory treadmill running testing (TRT). Field-based assessments were performed using the Hit and Turn Tennis Test (HTTT), the Yo-Yo Intermittent Recovery Test Level 1 (YYIRT) and the 20-m Multistage Shuttle Run Test (MSRT). The Wingate anaerobic test (WAnT), jumping ability (counter-movement jump (CMJ) and squat jump (SJ), and sprinting ability (5-m, 10-m and 20-m) were used for the determination of anaerobic performances. The results demonstrated that the distance covered in TRT was significantly correlated with all field tests in terms of distance covered (ranging from r = 0.56-0.64; p < 0.05). Significant correlations were also found between HTTT and TRT in terms of VO2max response (r = 0.46; p < 0.05). Moreover, the maximal running velocity calculated from the field tests was significantly correlated with the WaNT, jumping and sprinting abilities (ranging from r = 0.40-0.81; p < 0.05). The results of this study suggest that HTTT may be more suitable sport specific field test for determining required aerobic capacity responses in tennis players.
The Longitudinal Associations between Perceived Descriptive Peer Norms and Eating and Drinking Behavior: An Initial Examination in Young Adults

Experimental and cross-sectional studies indicate that perceptions of the eating and drinking behavior of one's peers (perceived descriptive peer norms) are associated with the types, frequency and quantity of food, and beverages a person chooses to consume. At present, we know very little about the longitudinal association between perceived descriptive peer norms and future eating or drinking behavior. In this study, we examined whether perceived descriptive peer norms for different food/beverage types predicted frequency of consumption of food/beverages in university students. Three hundred and forty participants completed measures at baseline and follow-up for frequency of consumption of cakes/pastries, sugar containing beverages, and alcoholic beverages, as well as measures of perceived descriptive peer norms at both time points. Perceived descriptive peer norms predicted consumption of pastries/cakes at follow up when controlling for changes in these perceptions over time; believing that one's peers frequently consumed cakes/pastries was associated with an increased frequency of consumption over time, although the magnitude of this effect was small. There was no significant association between perceived descriptive peer norms and changes in frequency of consumption of sugar containing beverages or alcohol over time. In the present longitudinal study of young adults, beliefs about how often one's peers eat or drink specific food and beverages types had limited effect on future eating and drinking behavior.
A Burst-Based “Hebbian” Learning Rule at Retinogeniculate Synapses Links Retinal Waves to Activity-Dependent Refinement

Patterned spontaneous activity in the developing retina is necessary to drive synaptic refinement in the lateral geniculate nucleus (LGN). Using perforated patch recordings from neurons in LGN slices during the period of eye segregation, we examine how such burst-based activity can instruct this refinement. Retinogeniculate synapses have a novel learning rule that depends on the latencies between pre- and postsynaptic bursts on the order of one second: coincident bursts produce long-lasting synaptic enhancement, whereas non-overlapping bursts produce mild synaptic weakening. It is consistent with “Hebbian” development thought to exist at this synapse, and we demonstrate computationally that such a rule can robustly use retinal waves to drive eye segregation and retinotopic refinement. Thus, by measuring plasticity induced by natural activity patterns, synaptic learning rules can be linked directly to their larger role in instructing the patterning of neural connectivity.
