Age-related changes in maximal power and maximal heart rate recorded during a ramped test in 114 cyclists age 15-73 years.

This study assessed age-related changes in power and heart rate in 114 competitive male cyclists age 15-73 years. Participants completed a maximal Kingcycle ergometer test with maximal ramped minute power (RMPmax, W) recorded as the highest average power during any 60 s and maximal heart rate (HRmax, beats/min) as the highest value during the test. From age 15 to 29 (n = 38) RMPmax increased by 7.

The meaning and experience of being a stroke survivor: an interpretative phenomenological analysis.

Purpose: To investigate the meaning and experience of being a stroke survivor.

Method: Qualitative in-depth semi-structured interviews were conducted with 10 stroke survivors (five face-to-face and five e-mail interviews). The interview data were transcribed verbatim (these were pre-transcribed in e-mail exchange) and analysed using Interpretative Phenomenological Analysis.

An interpretative phenomenological analysis of the embodiment of artificial limbs.

Purpose: To gain an understanding of the embodied perceptual experience of successful prosthesis.

Method: The data for this study were transcripts derived from in-depth semi-structured e-mail (n=21) and face-to-face (n=14) interviews, and the documentary analysis of an e-mail discussion group for prosthesis users. This qualitative data was subject to an Interpretative Phenomenological Analysis.

Mechanically braked Wingate powers: agreement between SRM, corrected and conventional methods of measurement.

In this study, we assessed the agreement between the powers recorded during a 30 s upper-body Wingate test using three different methods. Fifty-six men completed a single test on a Monark 814E mechanically braked ergometer fitted with a Schoberer Rad Messtechnik (SRM) powermeter. A commercial software package (Wingate test kit version 2.

The impact of political conflict on moral maturity: a cross-national perspective.

This cross-national study of moral reasoning among adolescents in Northern Ireland, Scotland and the Republic of Ireland, addresses the problem of possible moral truncation in Northern Ireland due to the political conflict. The Sociomoral Reflection Measure-Short Form (SRM-SF; Gibbs et al. (1992) Moral Maturity: Measuring the Development of Sociomoral Reflection.

Phonological short-term memory contributions to sentence processing in young children.

Two experiments investigated the contribution of phonological short-term memory to the processing of spoken sentences by 4- and 5-year-old children. In Experiment 1, sentences contained either short or longer words, and varied in syntactic structure. Overall, repetition but not comprehension of the sentences was significantly influenced by word length.

Changes in bodily awareness induced by immersive virtual reality.

The recent proliferation of virtual reality technology has attracted the interest of social scientists who study human behavior and perceptual experience. Such computer simulations are able to present technologically rendered environments, where the properties of the physical world are approximated or manipulated to varying degrees. The present study sought to investigate the influence of an immersive virtual experience on the perceptual awareness of the body.

A comparison of adolescent moderate-to-vigorous physical activity participation in relation to a sustained or accumulated criterion.

Contemporary guidelines for young people advocate both a sustained and accumulative approach to moderate-to-vigorous physical activity (MVPA) participation. In order to investigate the behavioural significance of applying these approaches, this study assessed if differences in adolescent MVPA occurred when either a sustained or accumulated criterion was adopted. Using heart rate thresholds indicative of intensity, the physical activity of 25 adolescents was assessed by monitoring heart rate over 3 days.

Computer problems: are some people jinxed?

To examine the popular notion that some people are 'jinxed' when using computers 111 undergraduate psychology students were 'jinxed' whilst trying to complete a task over the Internet. No evidence was found to support that notion.

Can receiver psychology explain the evolution of aposematism?

The evolution of aposematism is difficult to explain because: (1) new aposematic morphs will be relatively rare and thus risk extinction during predator education; and (2) aposematic morphs lack the protection of crypsis, and thus appear to invite attacks. I describe a simple method for evaluating whether rare aposematic morphs may be selectively advantaged by their effects on predator psychologies. Using a simulated virtual predator, I consider the advantages that might accrue to dispersed and aggregated morphs if aposematic prey can cause neophobic avoidance, accelerate avoidance learning and decelerate predator forgetting.

Warning signals, receiver psychology and predator memory.

This review identifies four receiver psychology perspectives that are likely to be important in the design and evolution of warning signals. Three of these perspectives (phobia, learning and prey recognition) have been studied in detail, and I include a brief review of recent work. The fourth, a memory perspective, has received little attention and is developed here.

Paranormal belief, experience, and the Keirsey Temperament Sorter.

121 college students completed the Anomalous Experience Inventory and the Keirsey Temperament Sorter. Multiple regression analyses provided significant models predicting both Paranormal Experience and Belief; the main predictors were the other subscales of the Anomalous Experience Inventory with the Keirsey variables playing only a minor role.

Testing Müllerian mimicry: an experiment with wild birds.

Experiments with wild birds feeding on pastry 'prey' were performed to test competing theories of Müllerian mimicry Conventional theories predict that all resemblances between defended prey will be mutually advantageous and, hence, Müllerian. In contrast, unconventional theories predict that, if there are inequalities in defences between mimetic species, the less well-defended prey may dilute the protection of the better defended species in a quasi-Batesian manner. This unconventional prediction follows from an assumption that birds learn about the edibilities of prey using rules of Pavlovian learning.

Cytokine expression by cultured osteoblasts from patients with osteoporotic fractures.

Human osteoblasts were derived in culture from explants of bone from patients who had recently suffered osteoporotic fractures and from patients with no evidence of osteoporosis. The expression of cytokine mRNA in these osteoblasts was subsequently determined by reverse transcriptase-linked polymerase chain reaction (RT-PCR). We have detected mRNA for IL-1beta, IL-3, IL-6, IL-8, TNF-alpha and -beta, and the three TGF-beta isoforms in the cells.

Ethical and legal issues.

This article considers the general issues surrounding screening, in particular the problems involved in the collection and use of information derived from screening. Different forms of screening entail particular problems, which have their own ethical complexities. The legal and ethical issues arising from screening are likely to assume greater significance.

Robot predators in virtual ecologies: the importance of memory in mimicry studies.

An important means of investigating gains and losses to prey caused by mimicry is through mathematical or computer constructs which represent and explore limited aspects of mimicry situations. Such studies use virtual predators which are usually simple automata, 'robots' that, through simple rules, vary virtual attack rates on virtual insect prey. In this paper I consider the effect of variations in predator memory and learning on mimicry dynamics.
