Personality Traits,Television Viewing,and the Cultivation Effect

This research investigates the impact of 3 personality traits—trait anxiety, sensation seeking, and psychoticism—on cultivation effects regarding perceptions of violence. A survey measuring violence prevalence estimates, personality traits, television consumption, and genre preferences was completed by 427 undergraduates. Results indicate that low trait–anxious individuals, and to a lesser extent high sensation seekers, are more susceptible to cultivation regarding personal vulnerability to crime whereas those low in psychoticism are susceptible to cultivation regarding societal violence perceptions. The worldview offered by these traits, as opposed to TV genre consumption or resonance, seems to best explain these effects.     

The uncertain representation ranking framework for concept-based video retrieval

Concept based video retrieval often relies on imperfect and uncertain concept detectors. We propose a general ranking framework to define effective and robust ranking functions, through explicitly addressing detector uncertainty. It can cope with multiple concept-based representations per video segment and it allows the re-use of effective text retrieval functions which are defined on similar representations. The final ranking status value is a weighted combination of two components: the expected score of the possible scores, which represents the risk-neutral choice, and the scores’ standard deviation, which represents the risk or opportunity that the score for the actual representation is higher. The framework consistently improves the search performance in the shot retrieval task and the segment retrieval task over several baselines in five TRECVid collections and two collections which use simulated detectors of varying performance.     

Am I missing something? The effects of absence from class on student performance

We analyse a rich dataset of Economics students at a UK university to identify causal effects of class absence on student performance, exploiting the random assignment of students and information on students’ class timetables to avoid selection problems. We use panel properties of the data to control for unobserved student factors such as ability and effort. Quantile regression results suggest that absence has adverse effects on performance – but these effects are causal only for the upper part of the conditional performance distribution.     

Codes Are Not Enough: What Philosophy Can Contribute To The Ethics Of Educational Research

Formal codes of ethics are not the best way of addressing ethical issues arising in educational research. Philosophers have often exaggerated the importance of such codes, although philosophy has little to contribute to them. What we need rather is a closer attention to the ways in which ethical decisions about research are actually made. Moral theory can contribute here by clarifying this process and identifying helpful procedures and strategies, such as those used by institutional review committees in arriving at good judgements. New and unfamiliar situations require us to extend our existing abilities, not to return to first principles and set up formal codes.     

Developmental Differences in Infant Attention to the Spectral Properties of Infant-directed Speech

Across several independent studies, infants from a few days to 9 months of age have shown preferences for infant-directed (ID) over adult-directed (AD) speech. Moreover, 4-month-olds have been shown to prefer sine-wave analogs of the fundamental frequency of ID speech, suggesting that exaggerated pitch contours are prepotent stimuli for infants. The possibility of similar preferences by 1-month-olds was examined in a series of experiments, using a fixation-based preference procedure. Results from the first 2 experiments showed that 1-month-olds did not prefer the lower-frequency pitch characteristics of ID speech, even though 1-month-olds were able to discriminate low-pass filtered ID and AD speech. Since low-pass filtering may have distorted the fundamental frequency characteristics of ID speech, 1-month-olds were also tested with sine-wave analogs of the fundamental frequencies of the ID utterances. Infants in this third experiment also showed no preference for ID pitch contours. In the fourth experiment, 1-month-olds preferred a natural recording of ID speech over a version which preserved only its lower frequency prosodic features. From these results, it is argued that, although young infants are similar to older infants in their attraction to ID speech, their preferences depend on a wider range of acoustic features (e.g., spectral structure). It is suggested that exaggerated pitch contours which characterize ID speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased perceptual acuity over the first months after birth.     

Embodiment and becoming in secondary drama classrooms: the effects of neoliberal education cultures on performances of self and of drama texts

This article explores the effects of neoliberalism and performative educational cultures on secondary school drama classrooms. We consider the ways Deleuze and Guattari’s schizoanalysis and Butler’s concept of gender performance enable us to chart the embodied, relational, spatial and affective energies that inhabit the often neoliberal and heterosexually striated space of the drama classroom. These post-humanist analyses are useful methodological tools for mapping the complexities of student becomings in the space context of the secondary school. We also show how Foucault’s governmentality and Ball’s theory of competitive performativity are particularly salient in the context of immanent capitalism that shapes the desires of its subjects. These frameworks, when combined, can be useful in critiquing neoliberal educational assemblages and in indicating emerging deterritorializations and lines of flight in teachers and students.
