Because elderly individuals experience marked declines in various physical functions (e.g., vision, joint function) simultaneously, it is difficult to clarify the individual effects of these functional declines on walking. However, by imposing vision and joint function restrictions on young men, the effects of these functional declines on walking can be clarified. The authors aimed to determine the effect of restricted vision and range of motion (ROM) of the knee joint on gait properties while walking and ascending or descending stairs. Fifteen healthy young adults performed level walking and stair ascent and descent during control, vision restriction, and knee joint ROM restriction conditions. During level walking, walking speed and step width decreased, and double support time increased significantly with vision and knee joint ROM restrictions. Stance time, step width, and walking angle increased only with knee joint ROM restriction. Stance time, swing time, and double support time were significantly longer in level walking, stair descent, and stair ascent, in that order. The effects of vision and knee joint ROM restrictions were significantly larger than the control conditions. In conclusion, vision and knee joint ROM restrictions affect gait during level walking and stair ascent and descent. This effect is marked in stair ascent with knee joint ROM restriction. 相似文献

To investigate gender differences in the dynaijiics of alcohol use, we gathered self-report data from male and female college students. Results of our experiment showed that dominance power motivations were correlated with negative drinking outcomes for both men and women; assertiveness power motivations were associated with negative outcomes only for women. For both sexes, a higher proportion of positive social motivations was associated with fewer negative drinking outcomes. We expect that, in addition to the more traditionally defined needs for dominance power shown to be important for drinking among men, women may use alcohol in relation to needs for assertiveness and self-expression. 相似文献

An investigation of the efficacy of sensory integrative treatment of the psychiatric status and physical functioning of patients with chronic schizophrenia is reported. Patients were involved in sequenced sensory integrative treatment over a seventeen week period. Significant improvement was found in scores of the NOSIE-30 as well as on some of the usual idicators of sensory integrative status: thumb-finger opposition, diadochokinesis, eye pursuits and balance. Length of treatment time was linearly related to amount of improvement. 相似文献

Service utilization patterns among children with severe emotional and/or behavioral disturbances are described for 89 children and families, interviewed at two time points across a 6-month period. Children received a greater number of individual therapy sessions than family therapy sessions, and children significantly decreased their levels of internalizing and externalizing behaviors. Family therapy was associated with decreases in internalizing behaviors when children reported outcomes. Individual therapy was not associated with changes in either internalizing or externalizing behaviors regardless of reporter. Symptom severity did not dictate whether children were provided individual or family therapy. Recommendations for individualized treatment plans are offered. 相似文献

Traditional family therapists often work with family members of similar cognitive levels and exclude small children from the therapeutic process. Recent research indicates that children and families benefit when all family members can be involved in counseling (e.g., Thompson, Bender, Cordoso, & Flynn, 2011). Using an integrative intervention model, this article will focus on specific play-based activities which can be used to effectively include children in family therapy. A developmental, step-by step protocol is introduced and specific play-based activities are discussed. 相似文献

The three lineages of information,—the genetic, the cultural and artifactual—will increasingly merge their constituent information contents through advances in biotechnology and information technology. This will redefine what constitutes “social” and what constitutes “community.” A community's members communicate with their “significant others” and change their internal information states (and their internal and external behaviors). Under conditions of merging, information exchanges occur across all the three lineages. In this sense, the concept of significant other,—that is, a communicating entity—, is now spread from human communities to encompass also the biological and the artifactual. A seamless merging between the three realms now occurs affecting their respective internal information stores. The resulting image of interactions that now arises is of multiple oceans of communities, operating at different levels, the genetic, the cultural and the artifactual. There are exchanges across the different levels, up and down and sideways, as information is translated from one realm to the other. These dynamics result in changes in the evolutionary characteristics of each lineage and sub‐lineage, including the internal perceptions from within a lineage, namely in the language of evolutionary epistemology, its “meanings” and “hypotheses” on the world. A future sociology must necessarily take into account these factors and incorporate the dynamics of all three realms. 相似文献

The “choreography of everyday life refers to the existence of rules of daily life, correspondingly to those of dances: the rules impose order upon individual behavior beyond the level of pure improvisation. The fact that acts of everyday life repeat themselves supports the idea that there exist some mechanisms generating order to daily practices. The replicative model of evolution is a candidate to explain this process of routinization. At the beginning of a replicative cycle behavioral patterns might change radically. In the course of time integrative and competitive selective forces start working. Finally some established rules, choreography, determining daily practices will emerge. In this mature phase identical replication takes place. 相似文献

This article pulls together the disjointed complexification of security studies. Such analytical overview suggests that the perspective of “timescapes” allows for exploring the complexity that shapes meanings and practices of security and its governance. In this respect, it is the imperative to change that suggests the significance of complexity thinking to security studies—that is, it is alone in taking the discontinuities of global life seriously. Security, in this regard, is not merely about the clockwork of survival, but is redefined through the cloudlike adaptive contingency of “security as resilience.” In this setting, the security governance of complexity is identified through its dancing to the timescaped rhythms of uncertainty, cognitive challenges, complex risks, and exaptation prompted by the heterogeneity of global life. 相似文献

This study examined the relationships between adaptive and maladaptive perfectionism, anxious and avoidant adult attachment styles, depression, hopelessness, and life satisfaction among a sample of 180 undergraduate students. Maladaptive perfectionism mediated the relationship between both forms of adult attachment and depression, hopelessness, and life satisfaction. Adaptive perfectionism mediated the relationship between avoidant adult attachment and hopelessness and life satisfaction. Implications for counselors and future research directions are discussed. 相似文献

An active duty Air Force ground combat unit (n = 189) completed surveys about trauma and combat exposure, mood symptoms, and meaning in life. Two dimensions of deployment-related traumas were assessed: combat (e.g., firing weapons, being fired upon) and aftermath (e.g., seeing dead bodies, injury). Results of regression analyses indicated that Airmen who experienced more intense combat reported less presence of meaning in life, although the significant interaction with gender suggested declines in meaning in life were especially pronounced among males with higher combat intensity. In contrast, more intense aftermath exposure was associated with slightly stronger meaning in life, with no differences by gender. Intensity of combat exposure might differentially affect perceived meaning in life for male versus female combatants. 相似文献
