A review of 50 years of research on naturally occurring family routines and rituals: Cause for celebration?

This article is a qualitative review of 32 publications appearing since J. Bossard and E. Boll's (1950) seminal work on family rituals was conducted. Definitions are offered whereby a distinction is made between family routines as observable practices and family rituals as symbolic representations of collective events. The relative occurrence of family routines, as described in the literature, appears to follow a developmental course and is affected by the cultural environment. Family routines and rituals were found to be related to parenting competence, child adjustment, and marital satisfaction. The studies were limited by inconsistent methods of assessing family routines, reliance on samples of convenience, and a failure to distinguish between direct and indirect effects. Recommendations are made to better integrate theory with empirical efforts to demonstrate the importance of family routines and rituals in contemporary life.

The convergent and discriminant validity of subjective fit perceptions.

This study examined whether employees develop perceptions about 3 different types of fit: person-organization fit, needs-supplies fit, and demands-abilities fit. Confirmatory factor analyses of data from 2 different samples strongly suggested that employees differentiate between these 3 types of fit. Furthermore, results from a longitudinal design of 187 managers supported both the convergent and discriminant validity of the different types of fit perceptions. Specifically, person-organization fit perceptions were related to organization-focused outcomes (e.g., organizational identification, citizenship behaviors, turnover decisions), whereas needs-supplies fit perceptions were related to job- and career-focused outcomes (e.g., job satisfaction, career satisfaction, occupational commitment). Although demands-abilities fit perceptions emerged as a distinct construct, they were not related to hypothesized outcomes (e.g., job performance, raises).

The behavioral effects of sugar: A comment on Buchanan.

Contends that studies undertaken to systematically examine the effects of sugar ingestion on the behavior of both hyperactive and normal children have failed to document any consistent adverse effects that would justify S. Buchanan's (see record 1985-25856-001) labeling of sugar as a toxin. It is suggested that unsupported statements do much to reinforce the fears of both parents and professionals, at the expense of reason.

Hypermnesia for pictures and words: Testing the recall level hypothesis.

Five experiments with 150 undergraduates examined the hypothesis that hypermnesia (improved recall across repeated tests) can be predicted from cumulative recall levels. Contrary to this view, Exp I demonstrated that when the cumulative recall levels for pictures and words were equated, pictures still produced a larger hypermnesic effect. Results of Exps II and III show that varying test length (and thus recall level) had no effect on the magnitude of the hypermnesic effect. In Exp IV, Ss studied a categorized word list and then received 1 21-min test or 3 7-min tests. Results suggest that (a) similar retrieval processes are used in these 2 conditions and (b) hypermnesia in the repeated test paradigm results from Ss generating covert cues to aid item recovery across tests. Overall findings suggest that although hypermnesia is related to cumulative recall levels, various other factors (e.g., item type) modulate the magnitude of the hypermnesia by affecting item accessibility across tests. It is argued that changes in item accessibility across tests, caused by learning during testing, play a major role in producing hypermnesia in both episodic and semantic memory tasks.

OOPS: a toolkit supporting mediation techniques for resolving ambiguity in recognition-based interfaces

Recognition technologies are being used extensively in both commercial and research systems. Recognizers are still error-prone however, and this results in performance problems and brittle dialogues, creating barriers to the acceptance and usefulness of recognition systems. Better interfaces to systems using recognition, which can help to reduce the burden of recognition errors, are difficult to build because of lack of knowledge about the ambiguity inherent in recognition. We present a survey of the design of correction techniques in interfaces which make use of recognizers. Based on this survey, we have created a user interface toolkit, OOPS (organized option pruning system) (Mankoff et al., Proceedings of ACM CHI 2000 Conference on Human Factors in Computing Systems, 2000, pp. 368–375). OOPS consists of a library of reusable error correction, or mediation, techniques drawn from the survey, combined with necessary architectural extensions to model and to provide structured support for ambiguity at the input event level of a GUI toolkit. The resulting infrastructure makes it easier for application developers to support error handling, thus helping to reduce the negative effects of recognition errors, and allowing us to explore new types of interfaces for dealing with ambiguity.     

Interaction between Macroinvertebrate Abundance and Habitat Use by Diving Ducks during Winter on Northeastern Lake Ontario

Although numbers of buffleheads (Bucephala albeola), common goldeneyes (Bucephala clangula) and long-tailed ducks (Clangula hyemalis) over-wintering on Lake Ontario have increased substantially over the past two decades, factors influencing habitat use and the potential for competition have not been investigated. The purpose of this study was to determine the relationship between prey availability and community structure of diving ducks during winter on northeastern Lake Ontario. Benthic and nektonic samples collected during fall, winter, and spring 2002–2004 indicated that macroinvertebrate numbers differed by location but generally did not decline throughout winter. Large accumulations of macroinvertebrates, apparently moved by wave action and currents, were documented in nearshore areas. Surveys showed that diving ducks congregated in mixed species flocks within areas of higher food abundance. Mixed species flocks were common in nearshore areas, likely because energydense foods (Amphipoda and Chironomidae) were abundant in the narrow zone of shallow water, close to shore. Although macroinvertebrate numbers likely affected habitat use by diving ducks, birds did not greatly reduce abundance of macroinvertebrates. It is unlikely that exploitative competition was occurring and interference competition appeared below threshold levels that would cause species to spatially segregate. Overall, our results suggest that food availability is not a limiting factor for buffleheads, common goldeneyes, or long-tailed ducks wintering on northeastern Lake Ontario.     

von Restorff revisited: Isolation, generation, and memory for order.

The effects of isolation and generation on memory for order were investigated in 4 experiments. Exp 1 and 2 examined the effect of isolation on order retention. Previous investigations in this area have yielded equivocal results. Experiments 1 and 2 revealed that isolation enhances memory for order: Isolated items were repositioned more accurately than comparable items in control lists. Experiments 3 and 4 investigated the effect of generation on order retention. These experiments revealed that generation can enhance, disrupt, or have no effect on memory for order, depending on the relative number of generated items appearing within a list. Implications of these results for general theoretical accounts of isolation effects in memory are discussed. A simplified feature model (J. S. Nairne, see record 1990-27505-001) is shown to provide a general account of isolation effects. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
