Slashing Smallville: The Interplay of Text, Audience and Production on Viewer Interpretations of Homoeroticism

This essay examines the slash community surrounding the television series Smallville. Utilizing textual data, audience survey responses, and fan ethnography, I locate the performance of homoeroticism in Smallville and highlight important (sub)textual moments of the series as recounted by participants. These observations reveal important implications concerning the performative capabilities of narrative, the cultural significance of this particular Superman retelling, and the influence of textual intent on subcultural practices related to the gay, lesbian, bisexual and transgender community. In essence, slash fans create an alternative vision of television narrative by marking each characters’ actions as homoerotic, which is rearticulated by the writers, directors and actors of the series. This interplay illustrates the changing nature of television narrative, where text, audience and production are inseparable when analyzing media artifacts.     

Spatial Simon effects and compatibility effects induced by observed gaze direction

Preconditions for the processing of observed gaze direction were studied by spatial Simon and compatibility effects. In five experiments, responses in the direction of a gaze were faster than responses in the opposite direction. Gaze direction influenced response speed although its processing was not required (Experiments 1, 2, 4, and 5). The result supports the notion of an inclination to process observed gaze direction in humans. However, the processes underlying the Simon effect of observed gaze direction were relatively time-consuming: Simon effects induced by gaze direction increased with response speed. Focusing of attention seemed to be part of the necessary processes: Simon effects were eliminated if attention was focused away from the eyes (Experiment 2). Further, if the processing of observed gaze direction was required, Simon effects by faces' observer-relative screen positions were absent (Experiment 3). Control conditions revealed that Simon effects by gaze direction can be produced with faces tilted by 90°, but that corresponding Simon effects do not result from numerical stimuli with an analogue spatial structure (Experiment 4), and that Simon effects result from gaze directions of scrambled faces (Experiment 5).     

Is there an age deficit in the selection of mental sets?

Efficient selection of actions is dependent on higher-level constraints (mental sets) on lower-level selection. This paper explores the hypothesis that ageing leads to specific impairments associated with higher-level selection between mental sets. Indirect evidence for such a deficit comes from occasional findings of age differences in situations with high executive-control demands (e.g., Mayr & Kliegl, 1993) that are not easily explained in terms of other factors, such as general slowing or working memory parameters. More direct evidence comes from recent results with the so-called task-switching paradigm. Specifically, age-sensitive set-selection processes are indicated by age differences in “global selection costs” (i.e., the response-time difference between task-switching blocks and single-task blocks) which seem to be particularly large when demands in terms of “keeping competing mental sets apart” are high. Finally, data from a new variant of the task-switching paradigm (the “fade-out paradigm”) are reported which show that age differences in global costs persist substantially beyond a phase in which set-selection is actually necessary. Generally, evidence is consistent with the view that in older age, a costly set-selection mode of processing dominates over the more efficient within-set-selection mode of processing, possibly because of a problem with maintaining distinct representations of what ought to be done in the face of competing representations of what could be done in principle.     

Influences of visibility,intentions, and probability in a peripheral cuing task

According to the concept of direct parameter specification, nonconsciously registered information can be processed to the extent that it matches currently active intentions of a person. This prediction was tested and confirmed in the current study. Masked visual information provided by peripheral cues led to reaction time (RT) effects only if the information specified one of the required responses (Experiments 1 and 3). Information delivered by the same masked cues that did not match the intentions was not used. However, the same information influenced RT if it was provided by visible cues (Experiments 2 and 3). The results suggest that the processing of nonconsciously registered information is flexible because it is susceptible to the changing intentions of a person. Yet, these processes are apparently restricted, as nonconsciously registered information cannot be used as easily for purposes not corresponding to the currently active intentions as better visible information.     

Fractal Dynamics of Heart Beat Interval Fluctuations in Corticotropin-Releasing Factor Receptor Subtype 2 Deficient Mice

Non-linear fractal analysis of cardiac interbeat time series was performed in corticotropin-releasing factor receptor subtype 2 (CRFR2) deficient mice. Heart rate dynamics in mice constitutes a self-similar, scale-invariant, random fractal process with persistent intrinsic long-range correlations and inverse power-law properties. We hypothesized that the sustained tachycardic response elicited by intraperitoneal (ip) injection of human/rat CRF (h/rCRF) is mediated by CRFR2. In wildtype control animals, heart rate was increased to about maximum levels (approximately 750 bpm) while in CRFR2-deficient animals baseline values were retained (approximately 580 bpm). The tachycardic response elicited by ip-application is mediated by CRFR2 and is interpreted to result from sympathetic stimulation. However, the functional integrity of CRFR2 would not present a prerequisite to maintaining the responsiveness and resiliency of cardiac control to external environmental perturbations experimentally induced by extrinsic ip-application of h/rCRF or under physiological conditions that may be associated with an increased peripheral release of CRF. Under stressful physiological conditions achieved by novelty exposure, CRFR2 is not involved in the cardiodynamic regulation to external short-term stress. While the hypothesis of involvement of CRFR2 in cardiac regulation upon pharmacological stimulation cannot be rejected, the present findings suggest that the mechanism of action is by sympathetic stimulation, but would not unambiguously allow to draw any conclusions as to the physiological role of CRFR2 in the control of cardiac dynamics.     

Evaluation of the Responding in Peaceful and Positive Ways (RIPP) Seventh Grade Violence Prevention Curriculum

We evaluated the impact of RIPP-7, a seventh grade violence prevention curriculum designed to strengthen and extend the effects of the sixth grade RIPP-6 curriculum. Classes of seventh graders at two urban middle schools serving predominantly African-American youth where RIPP-6 had been implemented the preceding school year were randomized to intervention (N = 239) and control groups (N = 237). Compared to students in the control group, students who participated in RIPP-7 had fewer disciplinary code violations for violent offenses during the following school year. A limited number of main effects were found on self-report outcome measures and measures of attitudes. Although significant main effects were not found on self-report measures of physical aggression, drug use, or anxiety, analyses of interactions with pretest scores indicated that intervention effects were significantly moderated by pretest scores for several outcome measures. Students most likely to benefit from the intervention were those who reported higher pretest rates of problem behaviors including violent behavior, nonphysical aggression, and delinquent behavior.     

Map-based navigation in mobile robots:: II. A review of map-learning and path-planning strategies

This article reviews map-learning and path-planning strategies within the context of map-based navigation in mobile robots. Concerning map-learning, it distinguishes metric maps from topological maps and describes procedures that help maintain the coherency of these maps. Concerning path-planning, it distinguishes continuous from discretized spaces and describes procedures applicable when the execution of a plan fails. It insists on the need for an integrated conception of such procedures, which must be tightly tailored to the specific robot that is used, notably to the capacities and limitations of its sensory-motor equipment, and to the specific environment that is experienced. A hierarchy of navigation strategies is outlined in the discussion, together with the sort of adaptive capacities each affords to cope with unexpected obstacles or dangers encountered on an animat or robot’s way to its goal.
