The influence of strategy video game and its background music on cognitive control

It has been acutely argued for decades about the exact influences of video games on players. The researchers are also unable to come to an agreement on the effects of video games on cognitive control. Some researchers found that the video games were harmful to sustained attention, working memory and cognitive flexibility. While some other researchers claimed that video game experience has a beneficial effect on visuospatial cognition, executive control functions and cognitive improvement. In order to find out the hidden factors that cause the inconsistent results in this field, present research made a strict control on the game genre, measure of cognitive control and players’ subjective immersion in video games, with the hope to investigate the influence of video games on cognitive control in a more subtle way.
Numerical investigation on vortex shedding from a hydrofoil with a beveled trailing edge

To better understand the vortex shedding mechanism and to assess the capability of our numerical methodology, we conducted numerical investigations of vortex shedding from truncated and oblique trailing edges of a modified NACA 0009 hydrofoil. The hybrid particle-mesh method and the vorticity-based subgrid scale model were employed to simulate these turbulent wake flows. The hybrid particle-mesh method combines the vortex-in-cell and the penalization methods. We have implemented numerical schemes to more efficiently use available computational resources. In this study, we numerically investigated vortex shedding from various beveled trailing edges at a Reynolds number of 106. We then compared the numerical results with the experimental data, which show good agreement. We also conducted numerical simulations of wakes behind the hydrofoil at rest in periodically varying flows. Results reveal that vortex shedding is affected by the periodicity of a free-stream flow, as well as the trailing-edge shape.
How Does TED Talk? A Preliminary Analysis

TED Talks is one of the leading science communication initiatives in the digital age. Although previous work has analyzed the demographics of speakers & audience reaction to TED Talks, there is a dearth of research into the actual content of these talks. The transcripts for TED videos were downloaded from the official TED website and analyzed as to word use by different speaker classes (male academics, female academics, male non-academics, and female non-academics). The two subpopulations (males vs. females; academics vs. non-academics) exhibited marked differences in the words that they used during their talks, which may indicate different sentiments, topical preoccupations, and goals for the presentation. Gender was an important variable throughout the study, indicating an issue worthy of further investigation.
Public procurement at local level in the netherlands: towards a better client-contractor cooperation in a competitive environment

In the early 1990s, Dutch municipalities procured works mainly by invited tenders. The drive behind this policy was to maintain continuity of the relationship and cooperation between client and contractor(s). Towards the turn of the century the procurement policy moved to more public tendering. This was supposed to ensure more competitive pressure and to minimize suspicion over ‘cosy’ contacts between client and contractors. This ‘more competition’ policy was promoted even more after the exposure in 2001 of widespread collusion in the Dutch construction industry. For a number of years after this, client-contractor relationships remained distant and formal under the process of traditional contracting, open tendering and low cost selection. In 2009 representatives from the municipalities and contractors mutually expressed the wish to explore more integrated and cooperative contracts. These municipalities became participants in Pioneering 1 to start pilot projects focusing on relational contracting or partnering for design and execution. The assumption was that more cooperative problem-solving would lead to less conflict and greater added value. The first pilot project is finished and the results are promising, but there are also some lessons. The willingness to cooperate between client and contractor existed during design and execution phase. The cooperation produced better solutions than the initial client solutions. Also, the focus on cooperation produced a more open atmosphere between client and contractor. However, this atmosphere sometimes hampered a critical attitude and influenced the process efficiency negatively. The delivery of reliable information by the client was especially critical and held back due to the time constraints caused by other projects also being executed. The tendering for qualitative criteria only and no prices led to competitive discussion about the budget. The new procurement law implemented on the 1
When work comes first: young adults in vocational education and training in Norway

Since reforms implemented in 1994, vocational education and training (VET) in Norway has been integrated and standardized as part of upper-secondary education. When young people enter upper-secondary education at the age of 15 or 16, they can choose either a vocational programme or a general academic programme. The standard model in vocational programmes is 2 years of school-based education, followed by 2 years of apprenticeship training. However, in practice, only a minority follow the standard route and acquire a trade certificate within 4 years. The average age upon completion of a vocational programme in Norway is 28 years, which is among the highest in the OECD. The purpose of this study was to explore personal trajectories within the Norwegian context to gain a better understanding of why people choose to obtain a trade certificate as young adults, instead of following the standardized route, drawn up by policy makers. Qualitative interviews were conducted with 34 people who obtained a trade certificate when they were aged between 25 and 35 years. The study showed that the opportunity to acquire formal VET qualifications through workplace learning provides an important second chance for many young adults in Norway. Based on the findings, we argue that policy makers need to see educational achievement in a long-term perspective and to design institutional structures that support learning opportunities at work, as well as in formal educational settings.

Gay Men In Brazil: Do Luxury Brands Extend Their Selves?

The consumption domain is where an individual and objects are put in contact, pursuing sense, producing social meanings and distinctions. Concerning symbolisms and consumption meanings, products have been an excellent source of information about their consumers. At the same time, consumers’ choices are made through a great variety of reasons, not easy to be predicted or understood. But frequently, consumers rely on the social meaning of products to mold their own image and talk about themselves through the customized goods that are consumed. The present study aims at understanding the relation between the extended self construct and the consumption of luxury branded clothing among male homosexuals. In other words, it aims at figuring out how specific products, herein the luxury clothing market, may be considered in the extended self composition of such consumers. In this way, an exploratory qualitative survey was carried out. A bibliographic review over the related topics pointed out significant particularities within the market for luxurious products as well as showed a review over marketing principles linked to brands, focusing in its image and identity aspects. Finally, it brought back the theory of the extended self and its application to the consumer behavior. Following that, 12 in-depth-interviews took place with representative individuals within this subculture, aiming at picking up and analyzing their perception towards the focused matter. Qualitative information has been added, with deep analysis of the interviewees’ perceptions, through the application of form with the Likert scale. Such approach aimed at evaluating the incorporation of clothing items to their extended self. Items which they have pointed out as relevant in their consumption of brands considered luxurious. At the end a conclusion is presented, showing that luxury brands clothing may have both a central or peripheral role in the composition of male homosexuals extended self.
Comparative Evaluation of Neural Network and Regression Based Models to Simulate Runoff and Sediment Yield in an Outer Himalayan Watershed

The complexity of rainfall-runoff-sediment yield hydrological processes remains a challenge for runoff and sediment yield prediction for large mountainous watersheds. In this study, a simple Non-Linear Dynamic (NLD) model has been employed for predicting daily runoff and sediment yield by considering the watershed memory based rainfall and runoff, and rainfall-runoff and sediment yield, respectively. The results were compared with two commonly used Artificial Neural Network (ANN) and Wavelet based ANN (WNN) models by taking maximum input parameters of values of time memory for rainfall, runoff, and sediment yield derived from the developed NLD model through stepwise regression. The feed forward ANN models with back propagation algorithm was used. Twenty-six years’ daily rainfall, runoff, and sediment yield data of Bino Watershed, Uttarakhand, were used in this study. The coefficient of determination, root mean square error, and model efficiency were adopted to evaluate the model’s performance. The results revealed a better performance by the ANN and WNN rainfall-runoff models compared to the NLD, however, NLD rainfall-runoff-sediment model showed higher efficiency than the ANN and WNN models in case of considering whole time series data. Under-prediction of sediment yield by all the models resulted from sudden landslides/flash floods in Himalayan Watersheds. The study showed that though WNN was better than ANN and NLD, its application cannot be generalized for entire mountainous watersheds. Again, criteria for successful selection of a useful subcomponent in WNN need to be developed. The study also indicates the greater capturing power of WNN for simulation of extreme flows with lowest percent-error-peak-flow values.
Analysis of the Application of the Concept of Corporate Social Responsibility in Local Businesses / Analiza Primene Koncepta Korporativne Društvene Odgovornosti U Domaćim Poslovnim Organizacijama

Abstract Modern society demands responsibility and contribution from its members. Social responsibility in business is related to the obligation of companies and other business organizations to increase their positive influence and reduce their negative influence on society. Corporate social responsibility represents a voluntary commitment on the part of an organization and its decision to choose and apply the appropriate business practices that contribute to the community. Nowadays, the concept of corporate social responsibility is standardized and represents an integral part of integrated management systems. The concept of corporate social responsibility in the domestic market has been applied in practice since the beginning of the process of economic transition, mostly in companies that are privatized by foreign capital. This study presents a model for the improvement of corporate social responsibility (CSR) in local business organizations, as a result of investigations related to the attitudes of managers in domestic companies regarding the question of corporate social responsibility Rezime Moderno društvo zahteva veliku odgovornost i doprinos svih svojih clanova. Društvena odgovornost u poslovanju se odnosi na obavezu kompanija i drugih poslovnih organizacija da povecaju pozitivni uticaj a smanje negativni uticaj na društvo. Korporativna društvena odgovornost podrazumeva dobrovoljno opredeljenje kompanije i njenu odluku da izabere i primenjuje odgovarajuce poslovne prakse koje doprinose zajednici. Koncept korporativne društvene odgovornosti je danas standardizovan i predstavlja sastavni deo integrisanih sistema menadžmenta. On se primenjuje na domacem tržištu od pocetka procesa ekonomske tranzicije, uglavnom u kompanijama koje su privatizovane stranim kapitalom. Ovaj rad prikazuje model za poboljšanje korporativne društvene odgovornosti (CSR) u domacim poslovnim organizacijama, kao rezultat ispitivanja stavova menadžera u domacim kompanijama o pitanjima koja se ticu korporativne društvene odgovornosti.
Maneuver-Based Generation of Motion Primitives for Differentially Constrained Motion Planning in State Lattices

In this paper, we propose a framework for generating motion primitives automatically. The user only needs to specify which type of maneuvers that should be included in the motion primitive set. Based on the selected maneuver types, the algorithm then solves a number of boundary value problems using numerical optimization. This significantly reduces the time consuming part of manually specifying all boundary value problems that should be solved. In addition, the framework allows for quick re-optimization of motion primitives after system parameter changes, which opens up the possibility to efficiently generate motion primitives for different types of platforms. We show in a numerical example that the framework also enhances the performance of the motion planner in terms of total cost for the produced solution.
Kinship, Social Structure, and the Ecological Bases for Sociality in Torch-Tail Spiny Rats, Trinomys yonenagae (Rodentia: Echimyidae): Evidence from Field and Molecular Data

Sociality (i.e., group-living) is a multi-dimensional aspect of behavior that occurs in many vertebrate species. Because living in spatially and behaviorally cohesive groups provides the foundation for most forms of complex, cooperative interactions, understanding the reasons for group-living is a fundamental goal for behavioral biologists. In mammals, ecological factors are hypothesized to play a major role in the formation of social groups; the ecological correlates of sociality in individual mammalian species, however, are often poorly understood. The torch-tail spiny rat (Trinomys yonenagae) is a South American hystricognath rodent endemic to semiarid sand dunes in northeastern Brazil. T. yonenagae is divergent from its congeners in that it is group-living, semi-fossorial, and desert-dwelling; other Trinomys species inhabit forests where individuals live aboveground and are solitary. To explore the adaptive bases for these distinctive attributes of T. yonenagae, I combined field studies with molecular genetic analyses to (1) characterize the social organization and kin structure of torch-tail spiny rats and (2) identify the primary ecological factors influencing sociality in this species. Most (76.2%) burrow systems monitored were occupied by more than one adult, including same-sex pairs, male-female pairs, and multiple adults of both sexes. Spatial overlap among burrow mates was extensive (72.0 ± 27.0%) and included the use of the same nest site. Kinship among adults decreased as the distance between the burrow systems in which individuals were resident increased. Burrow mates - particularly females - were typically close kin, although unrelated individuals (apparent immigrants from other burrow systems) were also detected within groups. Among adults captured in two successive field seasons, nearly half remained in the same burrow system; among the remaining animals, dispersal was male-biased. Individuals that dispersed to new burrow systems were more related to opposite-sex burrow mates than were individuals that remained in the same burrow system in consecutive years. At the same time, relatedness between dispersers and opposite-sex adults was lower in the new (as compared to the original) burrow system, suggesting that dispersal is related to inbreeding avoidance. Data regarding the distribution of vegetation on the study site revealed that proximity of food resources to a burrow system was significantly associated with group size. Protective vegetation and number of burrow openings, however, were better predictors of burrow sharing, suggesting that predation is the primary factor shaping social structure in this species. Comparisons of these findings with data from both other echimyids and other desert-dwelling rodent species yield intriguing new insights into the factors favoring sociality among burrow-dwelling rodents.
The future of professional forestry education: trends and challenges from the Malaysian perspective.

The traditional forestry education schemes are no longer sufficient to train professional foresters to manage the forest resources in a changing world. Even in forest-rich nations such as Malaysia, the challenges faced by forestry education are growing. The declining student enrolment and interests in the field must be stopped, if the field is to remain viable. The roles played by the forest have shifted from purely commercial products exploitation to environmental and social centric. In this context, forestry education will need to be restructured to impart the necessary knowledge and skills to the foresters to enable them to perform up to expectation in the field.

AbstractIn this paper, we proposed a new hardware architecture for motion estimation (ME) which is the most time-consuming unit among H.264 algorithms and designed to the type of intellectual property (IP). The proposed ME hardware consists of buffer, processing unit (PU) array, SAD (sum of absolute difference) selector, and motion vector (MVgenerator). PU array is composed of 16 PUs and each PU consists of 16 processing elements (PUs). The main characteristics of the proposed hardware are that current and reference frames are re-used to reduce the number of access to the external memory and that there is no clock loss during SAD operation. The implemented ME hardware occupies 3% hardware resources of StatixEP3SE80F1152C2 which is a FPGA of Altera Inc. and can operate at up to 446.43MHz. Therefore it can process up to 50 frames of 1080p in a second.Keyword : Data reuse, H.264/AVC standard, Motion Estimation, memory access reduction, Inter predictionBbc

Calcium hydroxide infl uence and intrachannel medication in apical leakage Infl uencia del hidróxido de calcio como medicación intraconducto en la microfi ltración apical

The purpose of this study was to determine the amount of remaining Ca(OH)2 after three removal techniques as well as determining its infl uence on apical seal. Eighty extracted mandibular premolars were prepared with ProTaper system ® , dressed with Ca(OH)2 paste and stored 10% humidity at 37 °C for 7 days. Experimental groups according to the removal technique were: NaCIO 2.5% + EDTA (G1), NaCIO 2.5% + EDTA 18% and ultrasonic activation (G2); NaCIO and ultrasonic activation (G3). Forty teeth were longitudinally split in order to measure remaining Ca(OH)2. The other 40 specimens were obturated with ultrasonic condensation of gutta-percha technique. These teeth were cleared and apical leakage was measured. Statistical analysis showed difference among groups with respect to Ca(OH) 2 removal (P < 0.03), Group G2 showed least amount of remaining Ca(OH)2. Likewise, leakage results showed statistical difference among groups (P < 0.01). Group 2 showed best results with respect to leakage. There was no statistical difference between groups 1 and 3. Conclusion: Irrigation with NaCIO 2.5% EDTA 18% and ultrasonic activation proved to be most effective in removing Ca(OH)2 from canal walls. Calcium hydroxide medication residuals inside canals might increase apical leakage.
