Physiological Reactions

This study tests whether playing violent video games leads to desensitization and increased cardiovascular responding. In a laboratory experiment, 42 men spent 20 min playing either a high- or low-violence version of a “first-person shooter” game. Arousal (heart rate, respiration rate) was measured continuously. After playing the game, emotional responses to aversive and aggressive stimuli - pictures from Lang, Bradley, and Cuthbert’s (1999) International Affective Picture System - were assessed with self-ratings and physiological measurement (skin conductance). Results showed no differences in the judgments of emotional responses to the stimuli. However, different effects of game violence emerged in the physiological reactions to the different types of stimulus material. Participants in the high-violence condition showed significantly weaker reactions (desensitization) to aversive stimuli and reacted significantly more strongly (sensitization) to aggressive cues. No support was found for the arousal hypothesis. Post-hoc analyses are used to discuss possible moderating influences of gaming experience and player’s trait aggressiveness in terms of the General Aggression Model ( Anderson & Bushman, 2001 ) and the Downward Spiral Model ( Slater, Henry, Swaim, & Anderson, 2003 ).

Transitioning to university may be especially difficult for students who expect perfection from themselves. Self-critical perfectionism has consistently been linked to poor mental health. The current study compares a diathesis-stress and a downward spiral model, to determine why self-critical perfectionism is detrimental for mental health during this transition. First-year students (N=658) were recruited prior to beginning university in August and contacted again in October, January, and April. Participants completed measures on perfectionism, stress and depressive symptoms. Evidence was found for a downward spiral model with self-critical perfectionism, but not a diathesis-stress model. Students higher in self-critical perfectionism were more likely to experience increased stress and depressive symptoms in a circular and additive manner. Conversely, students higher in personal standards perfectionism experienced less stress and subsequent depressive symptoms. This research provides a theoretical model for why self-critical perfectionism is related to poor mental health outcomes which become sustained over time.

Selection of a suitable Software Development Life Cycle (SDLC) model for project implementation is somewhat confusing as there are a lot of SDLC models with similar strengths and weaknesses. Also, the solutions proffered among the researchers so far have been the  qualitative comparative analysis of SDLC models. Hence, this paper proposes a comparative analysis of SDLC models using quantitative approach in relation to strengths and weaknesses of SDLC models. The study adapted comparative analysis and Software Development Life Cycle (SDLC) models features’ classification using ten characteristics such as project complexity, project size, project duration, project with risk, implementation/initial cost, error discovery, associated cost, risk analysis, maintenance and cost estimation. A quantitative measure that employs online survey using experts in software design and engineering, project management and system analysis was carried out for the evaluation of SDLC models. Purposeful Stratified Random Sampling (SRS) technique was used to gather the data for analysis using XLSTAT after pre-processing, taking into consideration both benefit and cost criteria. The overall performance evaluation showed that Spiral-Model is the best followed by V-Model and lastly Waterfall Model with comparative values of 38.63%, 35.76% and 25.61% respectively. As regards cost estimation, Waterfall Model is the most efficient with value of 41%, then V-Model with 31% and lastly Spiral Model with 28%. V-Model has great error recovery capability with value of 45% which is closely followed by Spiral Model with 37% and lastly Waterfall Model with 18%. The study revealed that, a model with efficient risk assurance does not guarantee efficient cost management. In the future work, more characteristics regarding SDLC models shall be considered.

Purpose Knowledge input development and innovation implementation are new features of industrial technology innovation. The purpose of this study is to find the process of coordination and ecological spiral in the ambidextrous innovation of industrial technology. Design/methodology/approach To design the model of industrial technology ambidextrous innovation based on knowledge ecology spiral, an input-output model of knowledge for ambidextrous innovation and a spiral model of knowledge ecology were constructed based on an improved Lotka-Volterra model. Then, the equilibriums in different knowledge inputs and the spiral evolution of knowledge ecology were analyzed. Finally, the ambidextrous coordination mechanism of the core organization was revealed. Findings By coordinating the knowledge inputs and the knowledge ecology spiral, enterprises extend the R&D investments in the innovation chain, which will facilitate the knowledge inputs of the exploitative and exploratory innovation. Implementing the ambidextrous coordination in the technology innovation chain and the knowledge ecology chain has the advantage of promoting knowledge inputs, mobility and ecological spiral. Meanwhile, it can achieve the “multi-source, integration and coordination” development of industrial technology innovation. Originality/value The two-element innovative knowledge input coordination model and the knowledge ecological spiral model based on the improved Lotka-Volterra model are constructed, which extends the modeling way of the traditional knowledge input-output profit model. It is expected to reduce the amount of knowledge input of a single member and provide theoretical reference for improving the efficiency of knowledge input by constructing the inter-dependent regenerative and inter-generative knowledge interaction.

Visual Changes

Abstract Changes in the visual form of newspapers are considered to be connected to changes in society, technologies, and aesthetic ideals. The present chapter explores the changes in the visual form of Estonia’s major newspapers between 1806 and 1940, and whether Mervola’s model of visual changes, in Finnish newspapers, is applicable to Estonia’s newspapers. Content analysis is used to analyse the data. The analysis shows that Estonian newspapers considerably changed their visual form twice during this period. These changes in visual form were linked to social and economic factors, and three specific influencers were present prior to both instances of change. At first, rapid social changes caused a volume-jump in the newspaper issue (1.5 times in five years), and then competition and journalistic professionalization were needed to trigger the changes in the visual form. Technical evolution did not force newspapers to change, but was instrumental only when social factors demanded changes.
