A Funny Thing Happened on the Way to the Ethics Board: Studying the Meaning of Farm Life for Farm Children

What can one expect to unfold when they choose to do a face-to-face study of children on the farm and their use of space in rural southwestern Ontario? The process of getting the research off the ground from an ethics point of view was one where it was anything but normative, and to a large extent, a grueling process. This article situates the researcher’s dilemma and lays out the unfolding of the research process with reference to the Tri-Council Policy Statement on Ethical Conduct for Research Involving Humans and the major components found to trouble a research ethics board on a university campus. Last, academic freedom and the rights of researchers are considered in the context of undertaking the proposed research agenda.     

An investigation into blocking of filial imprinting in the chick during exposure to a compound stimulus

The occurrence of "blocking" was investigated in jungle fowl chicks (Gallus gallus spadiceus B.) in an imprinting situation. In Experiment 1, chicks were simultaneously exposed to two stationary coloured cylinders, either two red cylinders (Group RR), a yellow and a red cylinder (YR), or two yellow cylinders (YY). After six days of exposure, the cylinders were removed from the cages and replaced by a yellow and a blue cylinder (i.e. YB) for each chick. This second phase of the experiment lasted for seven days. When the blue cylinder was presented alone during tests at different stages in Phase 2, the RR birds spent significantly more time with this cylinder and emitted fewer shrill calls than the chicks in the YR and YY groups. In Experiment 2, RR and YY birds were reared as in Experiment 1, except that in the second phase of the experiment they were exposed to a blue cylinder only. In this experiment the development of an attachment to the novel blue cylinder proceeded similarly in the RR and YY birds. In Experiment 3, it was found that chicks that were reared with a yellow and a red cylinder preferred the latter stimulus. Thus, although in the first phase of Experiment 1 the RR birds had been exposed to a more attractive stimulus, in tests during the second phase they spent more time with a novel stimulus (B) than the YY birds. These results are consistent with the suggestion that imprinting to a novel stimulus is "blocked" to some extent when that stimulus is presented in compound with another stimulus to which the animal has previously been exposed.     

Enumeration of dots: An eye movement analysis

The present study reports the measurement of response latencies and the recording of eye movements in a task in which adults had to enumerate dots in figures that differed in number of dots (n^d = 19–23) and grouping of dots. The functional relationship between latencies per dot and mean group size was in agreement with earlier findings (van Oeffelen & Vos, 1982). Temporal information from eye movement data indicated that the relative contribution of fixation durations to overall latency was far larger than the contribution of saccades, which superseded the contribution from eyeblinks. Spatial information in the form of eye movement trajectories indicated that, in general, there occurred one or two fixations at the starting position. From this position onward, eye movements were directed toward areas of dots rather than to each dot in particular. Scanning behavior was sometimes reiterative, in the sense that groups of dots were visited more than once. The results are discussed with respect to the nature of strategies employed during a dot-enumeration task.     

Technology in Medicine: Ontology,Epistemology, Ethics and Social Philosophy at the Crossroads

In reference to the different approaches in philosophy(of medicine) of the nature of (medical) technology,this article introduces the topic of this specialissue of Theoretical Medicine and Bioethics, that is,the way the different forms of medical technologyfunction in everyday medical practice. The authorselaborate on the active role technology plays inshaping our views on disease, illness, and the body,whence in shaping our world.     

The Association Between Internalizing and Externalizing Behavior in Childhood and Early Adolescence: Genetic or Environmental Common Influences?

This study analyzed the genetic and environmental influences on internalizing and externalizing behavior problems and the nature of their cooccurrence in a national Norwegian twin sample. The sample comprised 526 identical and 389 fraternal same-sexed twin pairs from five birth cohorts, aged 5-6, 8-9, 12-13, 13-14, and 14-15 years. Behavior problems were assessed by parental ratings on the Child Behavior Checklist. A model of additive genetic, shared, and nonshared environmental influences was fitted to both internalizing and externalizing behavior in four sex and age groups. The considerable covariance,r = .51 to .58, between these traits is accounted for mainly by common environmental components; this effect was most marked in the 5 to 9-year olds. Concordance rates for children scoring above 1 standard deviation from the total sample mean on the internalizing scale only, externalizing scale only, or both indicated stronger genetic influences for internalizing or externalizing problems only than for combined problems.     

Perceived tempo change is dependent on base tempo and direction of change: Evidence for a generalized version of Schulze's (1978) internal beat model

Assumptions of a theory, still influential, of tempo perception by Schulze (1978) are reconsidered in view of counter-evidence from other time-perception and timing studies. Specifically, it is shown that the role of base tempo of stimuli and the orientation of tempo change (acceleration versus deceleration) have to be incorporated in them. Therefore, Schulze's assumptions were extended so as to include the two stimulus parameters. A generalized version of Schulze's internal beat model, one of three formal elaborations of the theory, was tested in an experiment which required subjects (N = 17) to tell the direction of change (acceleration or deceleration) in metronomic tone sequences presented at tempi of 1, 2, or 4 Hz, the amount of tempo change being varied in steps of 2% between –10% (acceleration) and + 10%, including zero change. Psychometric curves obtained from logistic regression analysis showed the limitation of the original assumptions and supported the proposed generalization of Schulze's model. The validity of the theoretical interpretation of the data was discussed with respect to some methodological constraints in the experiment, such as the presentation of the different tempo conditions and the time length of the metronomic stimuli used, and with respect to their applicability to the performance of expressive drift (rubato versus accelerando) in music.     

Making Sense of a New Employment Relationship: Psychological Contract‐Related Information Seeking and the Role of Work Values and Locus of Control

This paper explores the information‐seeking behaviors newcomers engage in relating to their psychological contract and addresses the impact of work values (autonomy, advancement, group orientation and economic rewards) and work locus of control (LOC). We propose that these individual characteristics could explain differences in the frequency with which newcomers search for information about the promises their employer has made to them. A two‐wave longitudinal study was conducted in which 527 newcomers from eight organizations participated. The results largely support the proposed relationships between work values and contract‐related information seeking, while the relation between work LOC and contract‐related information seeking is rather weak. Implications for psychological contract formation are discussed.
