A topological inevitability of early developmental events through the use of classical topological concepts is discussed. Topological dynamics of forms and maps in embryo development are presented. Forms of a developing organism such as cell sets and closed surfaces are topological objects. Maps (or mathematical functions) are additional topological constructions in these objects and include polarization, singularities and curvature. Topological visualization allows us to analyze relationships that link local morphogenetic processes and integral developmental structures and also to find stable spatio-temporal topological characteristics that are invariant for a taxonomic group. The application of topological principles reveals a topological imperative: certain topological rules define and direct embryogenesis. A topological stability of embryonic morphogenesis is proposed and a topological scenario of developmental and evolutionary transformations is presented.  相似文献

In this study the authors investigated Gunnarsson's Tree Theme Method as an occupational therapy intervention program for mothers in recovery from addiction in accordance with Fisher and Hotchkiss's Model of Occupational Empowerment (2008 Fisher , G. , &; Hotchkiss , A. ( 2008 ). A model of occupational empowerment for marginalized populations in community environments . Occupational Therapy in Health Care , 22 , 5571 . Retrieved from EBSCOhost .[Crossref] [Google Scholar]). Each session of this mixed design study consisted of relaxation exercises, discussions on self-help readings, and participation in the Tree Theme Method. Two participants out of three improved their personal growth initiative. Participant reflection provided insight into the women's inner feelings. Fisher and Hotchkiss's model (2008 Fisher , G. , &; Hotchkiss , A. ( 2008 ). A model of occupational empowerment for marginalized populations in community environments . Occupational Therapy in Health Care , 22 , 5571 . Retrieved from EBSCOhost .[Crossref] [Google Scholar]) was supported as the women achieved personal growth. Further research is needed concerning how this may guide occupational therapy practice with disadvantaged populations.  相似文献

According to the verifiability approach, liars tend to provide details that cannot be checked by the investigator and awareness of this increases the investigator's ability to detect lies. In the present experiment, we replicated previous findings in a more realistic paradigm and examined the vulnerability of the verifiability approach to countermeasures. For this purpose, we collected written statements from 44 mock criminals (liars) and 43 innocents (truth tellers), whereas half of them were told before writing the statements that the verifiability of their statements will be checked. Results showed that ‘informing’ encouraged truth tellers but not liars to provide more verifiable details and increased the ability to detect lies. These findings suggest that verifiability approach is less vulnerable to countermeasures than other lie detection tools. On the contrary, in the current experiment, notifying interviewees about the mechanism of the approach benefited lie detection. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Taking an immediate recall test prior to misinformation exposure can increase eyewitness suggestibility—a finding termed retrieval‐enhanced suggestibility. Here, we examined whether retrieval‐enhanced suggestibility would occur when participants were administered an immediate Cognitive Interview (CI). The CI is an investigative interviewing technique that consistently elicits more correct details in memory reports than standard interviews. In this study, participants watched a video of a crime and then completed a distractor task (control condition), a free recall test, or the CI. They then heard misinformation presented in a narrative. Participants produced more accurate memory details in the CI than in free recall despite spending equal time on both tasks. However, the CI also increased the later report of misinformation relative to the control condition. These results show that initial retrieval can increase subsequent suggestibility even when such retrieval occurs under relatively ideal conditions. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Objective

Treatment decision‐making in bipolar II disorder is complex due to limited evidence on treatment efficacy and potentially burdensome side‐effects of options. Thus, involving patients and negotiating treatment options with them is necessary to ensure that final treatment decisions balance both clinician and patient preferences. This study qualitatively explored clinician views on (a) effective treatment decision‐making, unmet patient needs for (b) decision‐support and (c) information.

Method

Qualitative semi‐structured interviews with 20 practising clinicians (n = 10 clinical psychologists, n = 6 general practitioners, n = 4 psychiatrists) with experience treating adult outpatients with bipolar II disorder were conducted. Interviews were audiotaped, transcribed verbatim and analysed thematically using framework methods. Self‐report professional experience, and clinician preferences for patient decision‐making involvement were also assessed.

Results

Qualitative analyses yielded two inter‐related themes: (a) challenges and barriers to decision‐making and (b) facilitators of clinician decision‐making. Symptom severity, negative family attitudes, system‐based factors, and information gaps were thought to pose challenges to decision‐making. By contrast, decision‐making was supported by patient information, family involvement and patient‐centredness, and a strong therapeutic relationship. Clinician views varied depending on their professional background (medical vs clinical psychologist), patient involvement preferences, and whether the clinician was a bipolar specialist.

Conclusions

Whilst clinicians uniformly recognise the importance of involving patients in informed treatment decision‐making, active patient participation is hampered by unmet informational and decision‐support needs. Current findings inform a number of bipolar II disorder‐specific, clinician‐endorsed strategies for facilitating patient decision‐making, which can inform the development of targeted patient decision‐support resources for use in this setting.  相似文献

Few studies have focused on the relationships among religiousness, social support and subjective well‐being in Chinese adolescent populations. This study tries to fill this gap. Using cluster sampling, we selected two groups: Group A, which included 738 Tibetan adolescents with a formal religious affiliation and represented adolescents from a religious culture, and Group B, which included 720 Han adolescents without a religious affiliation and represented adolescents from an irreligious culture. Structural equation modelling showed that only in Group A did social support mediate (partially) the relationship between religious experience and subjective well‐being; furthermore, the results of a hierarchical regression analysis showed that only in Group A did social support moderate the relationship between religious ideology and subjective well‐being. Possible explanations for the discrepancies between the findings obtained in this study and those obtained in previous studies are discussed.  相似文献

The Cognitive Style Indicator (CoSI) includes 3 cognitive dimensions: creating (flexible, open-ended and inventive), knowing (emphasizing facts, details, objectivity, and rationality), and planning (guided by preferences for certainty and well-structured information). The first aim of this research was to validate the 3-factor structure of the CoSI within the Italian context. The second was to verify whether cognitive styles, as measured by the CoSI, accounted for individual differences in decision-making processes. Two studies were conducted using 2 different samples (n = 549 and n = 397). Confirmatory and multigroup factor analysis corroborated the 3-factor model and the measurement invariance of the instrument across genders. Reliability indices showed good internal consistency, as well as good levels of convergent and discriminant construct validity. Results from structural equation model revealed that cognitive styles, as measured by the CoSI, predicted individual differences in intuitive and deliberative decision-making processes. Findings gave evidence for the validity of the Italian version of the CoSI and for the causal relationship between cognitive styles and decision-making processes. Further research is needed to explore a more comprehensive model that includes, for example, personality.  相似文献

We evaluated a noncontingent reinforcement procedure that involved initially providing three subjects with signaled, continuous access to the functional reinforcer for aggression and slowly increasing the amount of time subjects were exposed to the signaled unavailability of the reinforcer. Additionally, alternative potential reinforcers were available throughout the sessions. Results showed immediate and substantial reductions in aggression for all three subjects. The clinical utility of this intervention is discussed, and future research directions are recommended.  相似文献
