Understanding the mechanisms supporting our comprehension of magnitude information represents a key goal in cognitive psychology. A major phenomenon employed in the pursuit of this goal has been the physical size congruity effect-namely, the observation that comparing the relative numerical sizes of two numbers is influenced by their relative physical sizes. The standard account of the physical size congruity effect attributes it to the automatic influence of the comparison of irrelevant physical magnitudes on numerical judgments. Here we develop an alternative account of this effect on the basis of the operation of attention in the typical size congruity display and the temporal dynamics of number comparison. We also provide a test of a number of predictions derived from this alternative account by combining a physical size congruity manipulation with a manipulation designed to alter the operation of attention within the typical size congruity display (i.e., a manipulation of the relative onsets of the digits). This test provides evidence consistent with an attentional contribution to the size congruity effect. Implications for our understanding of magnitude and the interactions between attention and magnitude are discussed.

The effects of incidental scents in the evaluation of environmental goods: The role of congruity.

We investigated whether pleasant ambient scents influence hypothetical and real money contributions toward environmental goods. We hypothesized that they would increase such contributions more when they were congruent with the target goods than when they were incongruent or when no scent was released. The results supported this congruity hypothesis. We offer a mental accessibility account: Pleasant scents that are congruent with a target good make positive information about that good more accessible and thus promote prosocial behavior. © 2014 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

A Goal Congruity Model of Role Entry, Engagement, and Exit: Understanding Communal Goal Processes in STEM Gender Gaps.

Diekman, Amanda B; Steinberg, Mia; Brown, Elizabeth R; Belanger, Aimee L; Clark, Emily K

2017-05-01

The goal congruity perspective provides a theoretical framework to understand how motivational processes influence and are influenced by social roles. In particular, we invoke this framework to understand communal goal processes as proximal motivators of decisions to engage in science, technology, engineering, and mathematics (STEM). STEM fields are not perceived as affording communal opportunities to work with or help others, and understanding these perceived goal affordances can inform knowledge about differences between (a) STEM and other career pathways and (b) women's and men's choices. We review the patterning of gender disparities in STEM that leads to a focus on communal goal congruity (Part I), provide evidence for the foundational logic of the perspective (Part II), and explore the implications for research and policy (Part III). Understanding and transmitting the opportunities for communal goal pursuit within STEM can reap widespread benefits for broadening and deepening participation.

McGrath, Mary C; Aronow, Peter M; Shotwell, Vivien

2016-01-01

We report the results of a 31-day trial on the effects of chocolate scent on purchasing behavior in a bookstore. Our study replicates and extends a 10-day randomized controlled trial in order to examine the generalizability of the original finding. We first introduce the study of store atmospherics and highlight the importance and dearth of replication in this area. In the next section, we describe the original study and discuss the theory of ambient scent effects on product sales, and the role of scent-product congruity. We then describe our design and methods, followed by presentation and discussion of our results. We find no evidence that chocolate scent affects sales. These findings indicate the importance of replication in varied settings. Contextual factors and the choices available to customers may moderate the effects of ambient scent on purchasing behavior. Our study highlights the value of examining the generalizability of experimental findings, both for theory and practice.

Image-Word Pairing-Congruity Effect on Affective Responses

NASA Astrophysics Data System (ADS)

Sanabria Z., Jorge C.; Cho, Youngil; Sambai, Ami; Yamanaka, Toshimasa

The present study explores the effects of familiarity on affective responses (pleasure and arousal) to Japanese ad elements, based on the schema incongruity theory. Print ads showing natural scenes (landscapes) were used to create the stimuli (images and words). An empirical study was conducted to measure subjects' affective responses to image-word combinations that varied in terms of incongruity. The level of incongruity was based on familiarity levels, and was statistically determined by a variable called ‘pairing-congruity status’. The tested hypothesis proposed that even highly familiar image-word combinations, when combined incongruously, would elicit strong affective responses. Subjects assessed the stimuli using bipolar scales. The study was effective in tracing interactions between familiarity, pleasure and arousal, although the incongruous image-word combinations did not elicit the predicted strong effects on pleasure and arousal. The results suggest a need for further research incorporating kansei (i.e., creativity) into the process of stimuli selection.

Who does she think she is? Women, leadership and the 'B'(ias) word.

PubMed

Kubu, Cynthia S

2018-02-01

Despite the increasing number of women in professional fields, women are under-represented in leadership roles. The goal of this paper is to identify potential explanations for the gender gap in leadership. The academic literature with respect to gender roles, leadership, and organizational expectations; gender differences in leadership; and the potential role of second generation bias was reviewed. Women are as effective as male leaders in a variety of organizational settings. The role congruity theory suggests that women are placed in a double bind: maintenance of their gender role may result in a failure to meet the requirements of a leader role whereas conforming to a leader role may result in the failure to conform to their gender role. Second generation, or implicit, bias also influences women's leadership opportunities. This is further complicated by expectations that women will engage in more altruistic organizational citizenship behaviors or be penalized. Differences in ability do not account for the gender gap in leadership. Cultural factors, including gender role and leadership expectations, organizational demands, and second-generation bias impact women's ability to lead. Pragmatic recommendations to increase women's influence and representation in leadership are provided.

Impaired analysis of signal conflict and congruence may contribute to diverse socio-emotional symptoms in frontotemporal dementias, however the underlying mechanisms have not been defined. Here we addressed this issue in patients with behavioural variant frontotemporal dementia (bvFTD; n = 19) and semantic dementia (SD; n = 10) relative to healthy older individuals (n = 20). We created auditory scenes in which semantic and emotional congruity of constituent sounds were independently probed; associated tasks controlled for auditory perceptual similarity, scene parsing and semantic competence. Neuroanatomical correlates of auditory congruity processing were assessed using voxel-based morphometry. Relative to healthy controls, both the bvFTD and SD groups had impaired semantic and emotional congruity processing (after taking auditory control task performance into account) and reduced affective integration of sounds into scenes. Grey matter correlates of auditory semantic congruity processing were identified in distributed regions encompassing prefrontal, parieto-temporal and insular areas and correlates of auditory emotional congruity in partly overlapping temporal, insular and striatal regions. Our findings suggest that decoding of auditory signal relatedness may probe a generic cognitive mechanism and neural architecture underpinning frontotemporal dementia syndromes.

Agentic women and communal leadership: how role prescriptions confer advantage to top women leaders.

PubMed

Rosette, Ashleigh Shelby; Tost, Leigh Plunkett

2010-03-01

The authors contribute to the ongoing debate about the existence of a female leadership advantage by specifying contextual factors that moderate the likelihood of the emergence of such an advantage. The investigation considered whether the perceived role incongruence between the female gender role and the leader role led to a female leader disadvantage (as predicted by role congruity theory) or whether instead a female leader advantage would emerge (as predicted by double standards and stereotype content research). In Study 1, it was only when success was internally attributed that women top leaders were evaluated as more agentic and more communal than men top leaders. Study 2 showed that the favorable ratings were unique to top-level positions and further showed that the effect on agentic traits was mediated by perceptions of double standards, while the effect on communal traits was mediated by expectations of feminized management skills. Finally, Study 2 showed that top women leaders were evaluated most favorably on overall leader effectiveness, and this effect was mediated by both mediators. Our results support the existence of a qualified female leadership advantage. 2010 APA, all rights reserved

Women's access to managerial positions: an experimental study of leadership styles and gender.

PubMed

Cuadrado, Isabel; Morales, J Francisco; Recio, Patricia

2008-05-01

This study attempts to test one of the explanations of the scarce representation of women in managerial positions, specifically the one advanced by "role congruity theory of prejudice toward female leaders" (Eagly & Karau, 2002), which appeals to the fact that women get unfavorable evaluations if they adopt male-stereotypical leadership styles. One-hundred and thirty-six undergraduate students participated in an experiment with a 2 (Male-stereotypical vs. Female-stereotypical leadership style) x 2 (Male vs. Female leader) design. Dependent variables were leader's competence, efficacy, and evaluation in a series of traits. It was found that, regardless of sex, the leaders were considered more competent and efficient, and were evaluated more favorably, when they adopted stereotypically feminine leadership styles. Implications of these findings for women's underrepresentation as leaders in management top positions worldwide are discussed.

Color congruity effect: where do colors and numbers interact in synesthesia?

PubMed

Cohen Kadosh, Roi; Henik, Avishai

2006-02-01

The traditional size congruity paradigm is a Stroop-like situation where participants are asked to compare the values of two digits and ignore the irrelevant physical sizes of the digits (e.g., 3 5). Here a color congruity paradigm was employed and the irrelevant physical sizes were replaced by irrelevant colors. MM, a digit-color synesthete, yielded the classical congruity effect. Namely, she was slower to identify numerically larger numbers when they deviated from her synesthetic experience than when they matched it. In addition, the effect of color on her comparative judgments was modulated by numerical distance. In contrast, performance of non-synesthetes was not affected by the colors. On the basis of neurophysiological studies of magnitude comparison and interference between numerical and physical information, it is proposed that the interaction between colors and digits in MM occurs at the conceptual level. Moreover, by using the current paradigm it is possible to determine the stage at which color-digit binding in synesthesia occurs.

Generality of a congruity effect in judgements of relative order.

PubMed

Liu, Yang S; Chan, Michelle; Caplan, Jeremy B

2014-10-01

The judgement of relative order (JOR) procedure is used to investigate serial-order memory. Measuring response times, the wording of the instructions (whether the earlier or the later item was designated as the target) reversed the direction of search in subspan lists (Chan, Ross, Earle, & Caplan Psychonomic Bulletin & Review, 16(5), 945-951, 2009). If a similar congruity effect applied to above-span lists and, furthermore, with error rate as the measure, this could suggest how to model order memory across scales. Participants performed JORs on lists of nouns (Experiment 1: list lengths = 4, 6, 8, 10) or consonants (Experiment 2: list lengths = 4, 8). In addition to the usual distance, primacy, and recency effects, instructions interacted with serial position of the later probe in both experiments, not only in response time, but also in error rate, suggesting that availability, not just accessibility, is affected by instructions. The congruity effect challenges current memory models. We fitted Hacker's (Journal of Experimental Psychology: Human Learning and Memory, 6(6), 651-675, 1980) self-terminating search model to our data and found that a switch in search direction could explain the congruity effect for short lists, but not longer lists. This suggests that JORs may need to be understood via direct-access models, adapted to produce a congruity effect, or a mix of mechanisms.

If you're going to be a leader, at least act like it! Prejudice towards women who are tentative in leader roles.

PubMed

Bongiorno, Renata; Bain, Paul G; David, Barbara

2014-06-01

Role congruity theory predicts prejudice towards women who meet the agentic requirements of the leader role. In line with recent findings indicating greater acceptance of agentic behaviour from women, we find evidence for a more subtle form of prejudice towards women who fail to display agency in leader roles. Using a classic methodology, the agency of male and female leaders was manipulated using assertive or tentative speech, presented through written (Study 1, N = 167) or verbal (Study 2, N = 66) communications. Consistent with predictions, assertive women were as likeable and influential as assertive men, while being tentative in leadership reduced the likeability and influence of women, but not of men. Although approval of agentic behaviour from women in leadership reflects progress, evidence that women are quickly singled out for disapproval if they fail to show agency is important for understanding how they continue to be at a distinct disadvantage to men in leader roles. © 2013 The British Psychological Society.

Response trajectories capture the continuous dynamics of the size congruity effect.

PubMed

Faulkenberry, Thomas J; Cruise, Alexander; Lavro, Dmitri; Shaki, Samuel

2016-01-01

In a comparison task involving numbers, the size congruity effect refers to the general finding that responses are usually faster when there is a match between numerical size and physical size (e.g., 2-8) than when there is a mismatch (e.g., 2-8). In the present study, we used computer mouse tracking to test two competing models of the size congruity effect: an early interaction model, where interference occurs at an early representational stage, and a late interaction model, where interference occurs as dynamic competition between response options. In three experiments, we found that the curvature of responses for incongruent trials was greater than for congruent trials. In Experiment 2 we showed that this curvature effect was reliably modulated by the numerical distance between the two stimulus numbers, with large distance pairs exhibiting a larger curvature effect than small distance pairs. In Experiment 3 we demonstrated that the congruity effects persist into response execution. These findings indicate that incongruities between numerical and physical sizes are carried throughout the response process and result from competition between parallel and partially active response options, lending further support to a late interaction model of the size congruity effect.

Hazan-Liran, Batel; Miller, Paul

2017-09-01

To determine whether and how learning is biased by competing task-irrelevant information that creates extraneous cognitive load, we assessed the efficiency of university students with a learning paradigm in two experiments. The paradigm asked participants to learn associations between eight words and eight digits. We manipulated congruity of the digits' ink colour with the words' semantics. In Experiment 1 word stimuli were colour words (e.g., blue, yellow) and in Experiment 2 colour-related word concepts (e.g., sky, banana). Marked benefits and costs on learning due to variation in extraneous cognitive load originating from processing task-irrelevant information were evident. Implications for cognitive load theory and schooling are discussed.

Background Identifying and understanding determinants of alcohol use behavior among Hispanic college students is an increasingly important public health issue, particularly during emerging adulthood. Studies examining ethnocultural determinants of alcohol use behavior among Hispanic college students have focused on direct associations with cultural orientation (e.g., acculturation and enculturation); yet there is a need for research that accounts for the complex interplay of other culturally relevant sociocultural factors. Objectives This study examined associations of behavioral acculturation, behavioral enculturation, and cultural congruity (perception of cultural fit between the values of the academic environment and the student's personal values) with alcohol use severity (AUS); and tested if gender moderated those associations. Methods A hierarchical linear regression and moderation analysis were conducted on a sample of 167 Hispanic emerging adults (ages 18 to 25) enrolled in college. Results All predictor variables entered in the regression model accounted for 20.9% of the variance in AUS. After controlling for demographic variables and depressive symptoms, behavioral acculturation and enculturation did not have a statistically significant association with AUS. Further, gender did not moderate either of these associations. Conversely, greater cultural congruity was associated with lower reports of AUS. A moderation analysis suggested that cultural congruity predicted lower reports of AUS among men, but not among women. Conclusions This was the first known study to examine the association of cultural congruity with alcohol use. Findings highlight the value of examining contextual factors of culture and moving beyond reductive measures of cultural orientation. PMID:26574656

The Influence of Sexual Orientation on the Perceived Fit of Male Applicants for Both Male- and Female-Typed Jobs.

PubMed

Clarke, Heather M; Arnold, Kara A

2018-01-01

Research demonstrates the bias faced by individuals engaged in occupations that are perceived as inconsistent with their gender. The lack of fit model and role congruity theory explain how gender stereotypes give rise to the perception that an individual lacks the attributes necessary to be successful in a gender-incongruent job. Men employed in jobs traditionally held by women are perceived as wimpy and undeserving of respect. The majority of studies in this area have, however, failed to account for the sexual orientation of the individual being rated. Therefore, we carried out an experiment where 128 adults with experience in recruitment and selection, recruited through Qualtrics, rated heterosexual and gay male applicants applying for a gender-typed job. The heterosexual male was rated less effectual, less respect-worthy, and less hirable in the female-typed job condition than in the male-typed job condition. The gay male applicant, however, was rated similarly on all criteria across job gender-types, suggesting the gay male applicant was viewed as androgynous rather than high in femininity and low in masculinity as inferred by implicit inversion theory. The implications of these findings are discussed.

Adults' acquisition of novel dimension words: creating a semantic congruity effect.

PubMed

Ryalls, B O; Smith, L B

2000-07-01

The semantic congruity effect is exhibited when adults are asked to compare pairs of items from a series, and their response is faster when the direction of the comparison coincides with the location of the stimuli in the series. For example, people are faster at picking the bigger of 2 big items than the littler of 2 big items. In the 4 experiments presented, adults were taught new dimensional adjectives (mal/ler and borg/er). Characteristics of the learning situation, such as the nature of the stimulus series and the relative frequency of labeling, were varied. Results revealed that the participants who learned the relative meaning of the artificial dimensional adjectives also formed categories and developed a semantic congruity effect regardless of the characteristics of training. These findings have important implications for our understanding of adult acquisition of novel relational words, the relationship between learning such words and categorization, and the explanations of the semantic congruity effect.

The present research addressed the question of whether need for closure (NFC; Kruglanski in The psychology of closed mindedness, Psychology Press, New York, 2004) biases individuals' memory of female leaders. Merging research on role congruity theory of leadership (Koenig et al. in Psychol Bull 4:616-642, 2011. https://doi.org/10.1037/a0023557 ) and research on retrieval-induced forgetting (RIF, Anderson et al. in J Exp Psychol Learn Mem Cognit 20:1063-1087, 1994. https://doi.org/10.1037/0022-3514.65.5.861 ), we hypothesized and found that high-NFC participants show (1) a higher RIF of dimensions commonly associated with the leadership prototype (agentic/masculine) ascribed to female manager targets, when selectively retrieved dimensions commonly associated with the female prototype (communal/feminine) were ascribed to the same target; and (2) a lessened RIF of female stereotypical dimensions ascribed to female manager targets, when selectively retrieved prototypical leadership dimensions were ascribed to the same target. Overall, the present findings suggest that when faced with women leaders, high NfC enhances the accessibility of gender stereotype-congruent memories and reduces the accessibility of prototypical leadership ones, thus reducing the RIF of communal/feminine memories.

In this functional magnetic resonance imaging study, 17 children were asked to make numerical and physical magnitude classifications while ignoring the other stimulus dimension (number–size interference task). Digit pairs were either incongruent (3 8) or neutral (3 8). Generally, numerical magnitude interferes with font size (congruity effect). Moreover, relative to numerically adjacent digits far ones yield quicker responses (distance effect). Behaviourally, robust distance and congruity effects were observed in both tasks. imaging baselline contrasts revealed activations in frontal, parietal, occipital and cerebellar areas bilaterally. Different from results usually reported for adultssmaller distances activated frontal, but not (intra-)parietal areas in children. Congruity effects became significant only in physical comparisons. Thus, even with comparable behavioural performance, cerebral activation patterns may differ substantially between children and adults. PMID:16603917

Higher order influences on evaluative priming: Processing styles moderate congruity effects.

PubMed

Alexopoulos, Theodore; Lemonnier, Aurore; Fiedler, Klaus

2017-01-01

A growing body of research challenges the automaticity of evaluative priming (EP). The present research adds to this literature by suggesting that EP is sensitive to processing styles. We relied on previous research showing that EP is determined by the extent to which the prime and the target events on a given trial are processed as a unified compound. Here, we further hypothesised that processing styles encouraging the inclusion of the prime to the target episode support congruity effects, whereas processing styles that enhance the exclusion of the prime from the target episode interrupt (or reverse) these effects. In Experiment 1, a preceding similarity search task produced a congruity effect, whereas a dissimilarity search task eliminated and (non-significantly) reversed this effect. In Experiments 2 and 3, we replicated and extended these findings using a global/local processing manipulation. Overall, these findings confirm that EP is flexible, open to top-down influences and strategic regulation.

Migration, cultural bereavement and cultural identity

PubMed Central

BHUGRA, DINESH; BECKER, MATTHEW A

2005-01-01

Migration has contributed to the richness in diversity of cultures, ethnicities and races in developed countries. Individuals who migrate experience multiple stresses that can impact their mental well being, including the loss of cultural norms, religious customs, and social support systems, adjustment to a new culture and changes in identity and concept of self. Indeed, the rates of mental illness are increased in some migrant groups. Mental health practitioners need to be attuned to the unique stresses and cultural aspects that affect immigrants and refugees in order to best address the needs of this increasing and vulnerable population. This paper will review the concepts of migration, cultural bereavement and cultural identity, and explore the interrelationship between these three aspects of the migrant's experience and cultural congruity. The complex interplay of the migration process, cultural bereavement, cultural identity, and cultural congruity, along with biological, psychological and social factors, is hypothesized as playing a major role in the increased rates of mental illness in affected migrant groups.

The current research investigated mood congruity effects in story recall using an embodied approach to mood induction involving a facial manipulation task with 3- and 4-year-old children. Participants held a chopstick or a popsicle stick in their mouths in a way to either produce or inhibit a smile while they listened to a story featuring happy events for a happy character and sad events for a sad character. Children's mood ratings before and after mood induction indicated that mood became more positive in the smile condition, with no change in the no smile condition. Children in the smile condition, but not in the no smile condition, remembered more about the happy character than the sad character in the story. These results extend mood congruity effects to 3- and 4-year olds, suggesting that at this age representations of emotion interact with basic memory processes. Moreover, the efficacy of reenactment of sensorimotor components of emotion in modifying mood is consistent with embodied representation of emotion during early childhood.

This meta-analysis investigates gender differences in economic negotiation outcomes. As suggested by role congruity theory, we assume that the behaviors that increase economic negotiation outcomes are more congruent with the male as compared with the female gender role, thereby presenting challenges for women's negotiation performance and reducing their outcomes. Importantly, this main effect is predicted to be moderated by person-based, situation-based, and task-based influences that make effective negotiation behavior more congruent with the female gender role, which should in turn reduce or even reverse gender differences in negotiation outcomes. Using a multilevel modeling approach, this meta-analysis includes 123 effect sizes (overall N = 10,888, including undergraduate and graduate students as well as businesspeople). Studies were included when they enabled the calculation of an effect size reflecting gender differences in achieved economic negotiation outcomes. As predicted, men achieved better economic outcomes than women on average, but gender differences strongly depended on the context: Moderator analysis revealed that gender differences favoring men were reduced when negotiators had negotiation experience, when they received information about the bargaining range, and when they negotiated on behalf of another individual. Moreover, gender differences were reversed under conditions of the lowest predicted role incongruity for women. In conclusion, gender differences in negotiations are contextually bound and can be subject to change. Future research is needed that investigates the underlying mechanisms of new moderators revealed in the current research (e.g., experience). Implications for theoretical explanations of gender differences in negotiation outcomes, for gender inequalities in the workplace, and for future research are discussed.

Mazerolle, Stephanie M; Borland, John F; Burton, Laura J

2012-01-01

Female athletic trainers (ATs) experience gender discrimination in the workplace due to stereotypical gender roles, but limited information is available regarding the topic. To understand the challenges and obstacles faced by young female ATs working in National Collegiate Athletic Association Division I athletics. Exploratory study using semistructured interviews. Division I clinical setting. A total of 14 female ATs were included in the study, using both criterion and snowball-sampling techniques. Their mean age was 27 ± 2 years, with 5 ± 2 years of overall clinical experience. Criteria included employment at the Division I clinical setting, being a full-time assistant AT, and at least 3 years of working experience but no more than 9 years to avoid role continuance. Analysis of the interview data followed inductive procedures as outlined by a grounded theory approach. Credibility was established by member checks, multiple-analyst triangulation, and peer review. Clear communication with both coaches and players about expectations and philosophies regarding medical care, a supportive head AT in terms of clinical competence, and having and serving as a role model were cited as critical tools to alleviate gender bias in the workplace. The female ATs in this study stressed the importance of being assertive with coaches early in the season with regard to the AT's role on the team. They reasoned that these actions brought forth a greater perception of congruity between their roles as ATs and their gender and age. We suggest that female athletic training students seek mentors in their field while they complete their coursework and practicums. The ATs in the current study indicated that a mentor, regardless of sex, helped them feel empowered to navigate the male-centric terrain of athletic departments by encouraging them to be assertive and not second-guess their decisions.

The generalizability of gender bias: Testing the effects of contextual, explicit, and implicit sexism on labor arbitration decisions.

PubMed

Girvan, Erik J; Deason, Grace; Borgida, Eugene

2015-10-01

Decades of social-psychological research show that gender bias can result from features of the social context and from individual-level psychological predispositions. Do these sources of bias impact legal decisions, which are frequently made by people subject to factors that have been proposed to reduce bias (training and accountability)? To answer the question, we examined the potential for 3 major social-psychological theories of gender bias (role-congruity theory, ambivalent sexism, and implicit bias) to predict outcomes of labor arbitration decisions. In the first study, undergraduate students and professional arbitrators made decisions about 2 mock arbitration cases in which the gender of the employee-grievants was experimentally manipulated. Student participants' decisions showed the predicted gender bias, whereas the decisions of experienced professionals did not. Individual-level attitudes did not predict the extent of the observed bias and accountability did not attenuate it. In the second study, arbitrators' explicit and implicit gender attitudes were significant predictors of their decisions in published cases. The laboratory and field results suggest that context, expertise, and implicit and explicit attitudes are relevant to legal decision-making, but that laboratory experiments alone may not fully capture the nature of their effect on legal professionals' decisions in real cases.

Huber, Stefan; Bahnmueller, Julia; Klein, Elise; Moeller, Korbinian

2015-10-01

Research on numerical cognition has addressed the processing of nonsymbolic quantities and symbolic digits extensively. However, magnitude processing of measurement units is still a neglected topic in numerical cognition research. Hence, we investigated the processing of measurement units to evaluate whether typical effects of multi-digit number processing such as the compatibility effect, the string length congruity effect, and the distance effect are also present for measurement units. In three experiments, participants had to single out the larger one of two physical quantities (e.g., lengths). In Experiment 1, the compatibility of number and measurement unit (compatible: 3 mm_6 cm with 3 < 6 and mm < cm; incompatible: 3 cm_6 mm with 3 < 6 but cm > mm) as well as string length congruity (congruent: 1 m_2 km with m < km and 2 < 3 characters; incongruent: 2 mm_1 m with mm < m, but 3 > 2 characters) were manipulated. We observed reliable compatibility effects with prolonged reaction times (RT) for incompatible trials. Moreover, a string length congruity effect was present in RT with longer RT for incongruent trials. Experiments 2 and 3 served as control experiments showing that compatibility effects persist when controlling for holistic distance and that a distance effect for measurement units exists. Our findings indicate that numbers and measurement units are processed in a componential manner and thus highlight that processing characteristics of multi-digit numbers generalize to measurement units. Thereby, our data lend further support to the recently proposed generalized model of componential multi-symbol number processing.

To remain competitive in the global economy, the United States (and other countries) is trying to broaden participation in science, technology, engineering, and mathematics (STEM) by graduating an additional 1 million people in STEM fields by 2018. Although communion (working with, helping, and caring for others) is a basic human need, STEM careers are often (mis)perceived as being uncommunal. Across three naturalistic studies we found greater support for the communal affordance hypothesis, that perceiving STEM careers as affording greater communion is associated with greater STEM career interest, than two alternative hypotheses derived from goal congruity theory. Importantly, these findings held regardless of major (Study 1), college enrollment (Study 2), and gender (Studies 1–3). For undergraduate research assistants, mid-semester beliefs that STEM affords communion predicted end of the semester STEM motivation (Study 3). Our data highlight the importance of educational and workplace motivational interventions targeting communal affordances beliefs about STEM. PMID:26806983

2009-02-01

For individuals with grapheme-color synesthesia, achromatic letters and digits elicit vivid perceptual experiences of color. We report two experiments that evaluate whether synesthesia influences overt visual attention. In these experiments, two grapheme-color synesthetes viewed colored letters while their eye movements were monitored. Letters were presented in colors that were either congruent or incongruent with the synesthetes' colors. Eye tracking analysis showed that synesthetes exhibited a color congruity bias-a propensity to fixate congruently colored letters more often and for longer durations than incongruently colored letters-in a naturalistic free-viewing task. In a more structured visual search task, this congruity bias caused synesthetes to rapidly fixate and identify congruently colored target letters, but led to problems in identifying incongruently colored target letters. The results are discussed in terms of their implications for perception in synesthesia.

The role of proprioception and neuromuscular stability in carpal instabilities.

PubMed

Hagert, E; Lluch, A; Rein, S

2016-01-01

Carpal stability has traditionally been defined as dependent on the articular congruity of joint surfaces, the static stability maintained by intact ligaments, and the dynamic stability caused by muscle contractions resulting in a compression of joint surfaces. In the past decade, a fourth factor in carpal stability has been proposed, involving the neuromuscular and proprioceptive control of joints. The proprioception of the wrist originates from afferent signals elicited by sensory end organs (mechanoreceptors) in ligaments and joint capsules that elicit spinal reflexes for immediate joint stability, as well as higher order neuromuscular influx to the cerebellum and sensorimotor cortices for planning and executing joint control. The aim of this review is to provide an understanding of the role of proprioception and neuromuscular control in carpal instabilities by delineating the sensory innervation and the neuromuscular control of the carpus, as well as descriptions of clinical applications of proprioception in carpal instabilities. © The Author(s) 2015.

The action-sentence compatibility effect in Japanese sentences.

PubMed

Awazu, Shunji

2011-10-01

The action-sentence compatibility effect (ACE) is a phenomenon in which a reader's response to a sentence is made faster when there is congruity between the action described in the sentence and the action that makes up the response. Previous studies showed the ACE occurs in action-related sentences in several languages. However, all these were SVO (verb-object) languages, in which verbs are placed before object nouns; this order is reversed in SOV languages. Moreover, those studies investigated hand responses. This study assessed the existence of the ACE in Japanese, an SOV language, and in foot responses. 24 female participants judged the sensibility of Japanese sentences that described actions and responded with either their foot or hand as an effector. Reaction times were significantly faster when there was congruity between the effector described in the sentences and the effector actually used for the response. However, sentence dependency was also found in the foot responses.

Relational demography in the workplace and health: an analysis of gender and the subordinate-superordinate role-set.

PubMed

Schieman, Scott; McMullen, Taralyn

2008-09-01

Using data from a 2005 national survey of working adults in the United States, we examine the effects of the gender composition of the superordinate-subordinate role-set on mental and physical health measures. Subordinates' and superordinates' genders are important determinants. Men who work in gender-mixed superordinate contexts (i.e., with one male and one female superior) report lower levels of distress and physical symptoms than men who work with one male superior. Women who work with one male superior report less distress and fewer physical symptoms compared to women who work with one female superior or in gender-mixed superordinate contexts. With a few exceptions, these observations generally hold net of occupation, job sector, and an array of work-related conditions. We discuss the implications of these findings in light of predictions derived from the similarity-attraction and role congruity theories. We also outline ways that theoretical development in relational demography can be refined by a more specific focus on the demographic characteristics--especially gender--of the superordinate-subordinate role-set.

Attitudes vs. Purchase Behaviors as Experienced Dissonance: The Roles of Knowledge and Consumer Orientations in Organic Market

Hidalgo-Baz, María; Martos-Partal, Mercedes; González-Benito, Óscar

2017-01-01

This research focuses on the incongruity between positive attitudinal responses but a lack of purchase behavior in organic markets. According to cognitive dissonance theory, consumer orientations toward the benefits attributed to organic products (environmental protection, health, hedonic) relieve the dissonance that results from this attitude–behavior incongruity. Knowledge also functions as a transmitter, from positive attitudes to purchase behaviors, thereby reducing the incongruity. Using quota sampling in a survey study, this paper tests the hypotheses from linear regression models. The results show that orientations and knowledge improve the congruity between attitudes and purchase behaviors toward organic products. Moreover, interaction effects arise between the environmental protection orientation and knowledge and between the hedonic orientation and knowledge. Increasing knowledge mitigates the difference between attitudes and purchase behaviors, especially for consumers with environmental protection or hedonic orientations. These findings have several important implications for research and practice. PMID:28286489

Value of Early Postoperative Computed Tomography Assessment in Ankle Fractures Defining Joint Congruity and Criticizing the Need for Early Revision Surgery.

Previous investigators have questioned the reliability of plain radiographs in assessing the accuracy of ankle fracture reduction when these were compared with the computed tomography (CT) evaluation in the preoperative setting, in particular, in fractures with syndesmosis injuries or trimalleolar fragments. The role of CT assessment, however, has not been investigated in the early postoperative setting. In the early postoperative setting, reduction still relies most commonly on fluoroscopy and plain radiographs alone. In the present study, we hypothesized that early postoperative CT assessment of ankle fractures with syndesmosic injuries and posterior malleolar fragments can add valuable information about the joint congruity compared with plain radiographs alone and that this information could affect the decisions regarding the need for early revision surgery. A total of 352 consecutive operated ankle fractures were reviewed. Of these, 68 (19%) underwent early postoperative CT assessment and were studied further to identify the causes that prompted revision surgery. Of the 68 cases, despite acceptable reduction found on the plain radiographs, 20 (29%) underwent early (within 1 week) revision surgery after studying the CT scans, which revealed malreduction of the syndesmosis, malreduction of the posterior lip fragment, and intra-articular fragments. We concluded that in ankle fractures involving disruptions of the syndesmosis or posterior malleolar fragments, early postoperative CT assessment could be justified, because it will reveal malreduction and prompt early revision intervention for a substantial proportion of these patients.

Enhancing semantic congruity effects with category-contingent comparative judgments

PubMed Central

Leth-Steensen, Craig; Petrusic, William M.; Shaki, Samuel

2014-01-01

In each of two experiments the direction of a binary comparison was contingent on the category of the stimulus pair. In one experiment, participants had to compare the size of animals from memory. On congruent trials, they had to select the smaller animal if both were small and the larger if both were large and on incongruent trials they selected the larger if both were small and the smaller if both were large. In a second experiment, participants had to compare visual extents and the direction of the comparison was contingent on whether the lines were short or long. Response times were increased and semantic congruity effects (SCEs) were greatly amplified with the category-contingent instructions relative to the conventional non-contingent instructions, precisely as predicted by the class of evidence accrual models of decisional processing and contrary to the single-sample stage models of the SCE.

Concept mapping-An effective method for identifying diversity and congruity in cognitive style.

PubMed

Stoyanov, Slavi; Jablokow, Kathryn; Rosas, Scott R; Wopereis, Iwan G J H; Kirschner, Paul A

2017-02-01

This paper investigates the effects of cognitive style for decision making on the behaviour of participants in different phases of the group concept mapping process (GCM). It is argued that cognitive style should be included directly in the coordination of the GCM process and not simply considered as yet another demographic variable. The cognitive styles were identified using the Kirton Adaption-Innovation Inventory, which locates each person's style on a continuum ranging from very adaptive to very innovative. Cognitive style could explain diversity in the participants' behaviour in different phases of the GCM process. At the same time, the concept map as a group's common cognitive construct can consolidate individual differences and serves as a tool for managing diversity in groups of participants. Some of the results were that: (a) the more adaptive participants generated ideas that fit to a particular, well-established and consensually agreed paradigm, frame of reference, theory or practice; (b) the more innovative participants produced ideas that were more general in scope and required changing a settled structure (paradigm, frame of reference, theory or practice); and (c) the empirical comparison of the map configurations through Procrustes analysis indicated a strong dissimilarity between cognitive styles.

Progressive valgus angulation of the ankle secondary to loss of fibular congruity treated with medial tibial hemiepiphysiodesis and fibular reconstruction.

PubMed

Lesiak, Alex C; Esposito, Paul W

2014-06-01

The fibula is an important stabilizer of the lateral ankle. Discontinuity of the fibular shaft can lead to progressive pain and shortening of the fibula, ultimately causing loss of lateral support to the ankle. Two children, who sustained segmental bone loss of the shaft of the fibula, developed progressive symptomatic valgus of the ankle with widening of the mortice and lateral subluxation of the talus. Both patients were treated with fibular plating and grafting with tricalcium sulfate with acute reconstitution of fibular length. Distal medial tibial hemiepiphysiodesis was simultaneously performed. One patient required revision plating and grafting 14 months after the index surgery because of plate failure. The valgus angulation and the widened medial mortice were corrected in the ankles of both patients, who returned to full activities. The patients were followed to maturity; the correction has been maintained, and they remain asymptomatic. The technique used in these cases can correct valgus angulation secondary to loss of fibular congruity rather than only halting progression of the deformity.

What is your neural function, visual narrative conjunction? Grammar, meaning, and fluency in sequential image processing.

PubMed

Cohn, Neil; Kutas, Marta

2017-01-01

Visual narratives sometimes depict successive images with different characters in the same physical space; corpus analysis has revealed that this occurs more often in Japanese manga than American comics. We used event-related brain potentials to determine whether comprehension of "visual narrative conjunctions" invokes not only incremental mental updating as traditionally assumed, but also, as we propose, "grammatical" combinatoric processing. We thus crossed (non)/conjunction sequences with character (in)/congruity. Conjunctions elicited a larger anterior negativity (300-500 ms) than nonconjunctions, regardless of congruity, implicating "grammatical" processes. Conjunction and incongruity both elicited larger P600s (500-700 ms), indexing updating. Both conjunction effects were modulated by participants' frequency of reading manga while growing up. Greater anterior negativity in frequent manga readers suggests more reliance on combinatoric processing; larger P600 effects in infrequent manga readers suggest more resources devoted to mental updating. As in language comprehension, it seems that processing conjunctions in visual narratives is not just mental updating but also partly grammatical, conditioned by comic readers' experience with specific visual narrative structures.

Meniscal tears

2010-01-01

The menisci are two semilunar-shaped fibrocartilagenous structures, which are interposed between the femoral condyles and tibial plateaux. They have an important role in knee function. Long-term follow-up studies showed that virtually all meniscectomized knees develop arthritic changes with time. The meniscus has functions in load bearing, load transmission, shock absorption, joint stability, joint lubrication, and joint congruity. Because of these functions, meniscal tissue should be preserved whenever possible. A well-trained surgeon can safely rely on clinical examination for diagnosing meniscal injuries. History and clinical examination are at least as accurate as magnetic resonance imaging in the skilled orthopedic surgeon’s hand. When meniscal repair is not possible, partial resection of the meniscus is indicated. Meniscal repair has evolved from open to arthroscopic techniques, which include the inside-out and outside-in suture repairs and the all-inside techniques. Meniscal transplantation is generally accepted as a management alternative option for selected symptomatic patients with previous complete or near-complete meniscectomy. PMID:24198542

Scene incongruity and attention.

PubMed

Mack, Arien; Clarke, Jason; Erol, Muge; Bert, John

2017-02-01

Does scene incongruity, (a mismatch between scene gist and a semantically incongruent object), capture attention and lead to conscious perception? We explored this question using 4 different procedures: Inattention (Experiment 1), Scene description (Experiment 2), Change detection (Experiment 3), and Iconic Memory (Experiment 4). We found no differences between scene incongruity and scene congruity in Experiments 1, 2, and 4, although in Experiment 3 change detection was faster for scenes containing an incongruent object. We offer an explanation for why the change detection results differ from the results of the other three experiments. In all four experiments, participants invariably failed to report the incongruity and routinely mis-described it by normalizing the incongruent object. None of the results supports the claim that semantic incongruity within a scene invariably captures attention and provide strong evidence of the dominant role of scene gist in determining what is perceived.

Gender-typing of leadership: evaluations of real and ideal managers.

PubMed

Cuadrado, Isabel; García-Ael, Cristina; Molero, Fernando

2015-04-01

This research focuses on female underrepresentation in managerial positions. Specifically, two studies examine gender-typing for managerial roles in Spain using ratings for real and ideal managers. In addition, we analyse the existence of same-gender bias on evaluations of the behavior of actual leaders. In the first study, 195 Spanish workers evaluate the extent to which gender-stereotypical traits are important for becoming a successful middle manager in three conditions (female managers, male managers, and managers in general). In the second study, we explore the degree to which the behavior of real Spanish managers is gender-typed and the existence of same-gender bias on leadership styles - transformational, transactional and avoidant/passive - and on leadership outcomes - effectiveness, extra effort and satisfaction - from the perspective of subordinates (N = 605). Overall, the results demonstrate that masculine characteristics were rated as more important than feminine characteristics for managerial positions, and they were more often assigned to male managers than to female managers. Unexpectedly, this manager-male association is stronger among female participants than among male participants. Our findings also demonstrate that women subordinates evaluate their same-sex supervisors more favorably in transformational leadership, effectiveness, and extra effort. The negative consequences derived from gender-typing managerial positions are highlighted according to the role congruity theory of prejudice toward female leaders. The positive effects of in-group female bias on behavior ratings are also noted. The mixed implications of these results for women's advancement to leadership positions are discussed. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Malleability in communal goals and beliefs influences attraction to stem careers: evidence for a goal congruity perspective.

PubMed

Diekman, Amanda B; Clark, Emily K; Johnston, Amanda M; Brown, Elizabeth R; Steinberg, Mia

2011-11-01

The goal congruity perspective posits that 2 distinct social cognitions predict attraction to science, technology, engineering, or mathematics (STEM) fields. First, individuals may particularly value communal goals (e.g., working with or helping others), due to either chronic individual differences or the salience of these goals in particular contexts. Second, individuals hold beliefs about the activities that facilitate or impede these goals, or goal affordance stereotypes. Women's tendency to endorse communal goals more highly than do men, along with consensual stereotypes that STEM careers impede communal goals, intersect to produce disinterest in STEM careers. We provide evidence for the foundational predictions that gender differences emerge primarily on communal rather than agentic goals (Studies 1a and 3) and that goal affordance stereotypes reflect beliefs that STEM careers are relatively dissociated from communal goals (Studies 1b and 1c). Most critically, we provide causal evidence that activated communal goals decrease interest in STEM fields (Study 2) and that the potential for a STEM career to afford communal goals elicits greater positivity (Study 3). These studies thus provide a novel demonstration that understanding communal goals and goal affordance stereotypes can lend insight into attitudes toward STEM pursuits.

Walking at non-constant speeds: mechanical work, pendular transduction, and energy congruity.

PubMed

Balbinot, G

2017-05-01

Although almost half of all walking bouts in urban environments consist of less than 12 consecutive steps and several day-to-day gait activities contain transient gait responses, in most studies gait analysis is performed at steady-state. This study aimed to analyze external (W ext ) and internal mechanical work (W int ), pendulum-like mechanics, and elastic energy usage during constant and non-constant speeds. The mechanical work, pendular transduction, and energy congruity (an estimate of storage and release of elastic energy) during walking were computed using two force platforms. We found that during accelerating gait (+NCS) energy recovery is maintained, besides extra W + ext , for decelerating gait (-NCS) poor energy recovery was counterbalanced by W - ext and C% predominance. We report an increase in elastic energy usage with speed (4-11%). Both W - ext and %C suggests that elastic energy usage is higher at faster speeds and related to -NCS (≈20% of elastic energy usage). This study was the first to show evidences of elastic energy usage during constant and non-constant speeds. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Are leader stereotypes masculine? A meta-analysis of three research paradigms.

PubMed

Koenig, Anne M; Eagly, Alice H; Mitchell, Abigail A; Ristikari, Tiina

2011-07-01

This meta-analysis examined the extent to which stereotypes of leaders are culturally masculine. The primary studies fit into 1 of 3 paradigms: (a) In Schein's (1973) think manager-think male paradigm, 40 studies with 51 effect sizes compared the similarity of male and leader stereotypes and the similarity of female and leader stereotypes; (b) in Powell and Butterfield's (1979) agency-communion paradigm, 22 studies with 47 effect sizes compared stereotypes of leaders' agency and communion; and (c) in Shinar's (1975) masculinity-femininity paradigm, 7 studies with 101 effect sizes represented stereotypes of leadership-related occupations on a single masculinity-femininity dimension. Analyses implemented appropriate random and mixed effects models. All 3 paradigms demonstrated overall masculinity of leader stereotypes: (a) In the think manager-think male paradigm, intraclass correlation = .25 for the women-leaders similarity and intraclass correlation = .62 for the men-leaders similarity; (b) in the agency-communion paradigm, g = 1.55, indicating greater agency than communion; and (c) in the masculinity-femininity paradigm, g = 0.92, indicating greater masculinity than the androgynous scale midpoint. Subgroup and meta-regression analyses indicated that this masculine construal of leadership has decreased over time and was greater for male than female research participants. In addition, stereotypes portrayed leaders as less masculine in educational organizations than in other domains and in moderate- than in high-status leader roles. This article considers the relation of these findings to Eagly and Karau's (2002) role congruity theory, which proposed contextual influences on the incongruity between stereotypes of women and leaders. The implications for prejudice against women leaders are also considered.

Visual search for conjunctions of physical and numerical size shows that they are processed independently.

PubMed

Sobel, Kenith V; Puri, Amrita M; Faulkenberry, Thomas J; Dague, Taylor D

2017-03-01

The size congruity effect refers to the interaction between numerical magnitude and physical digit size in a symbolic comparison task. Though this effect is well established in the typical 2-item scenario, the mechanisms at the root of the interference remain unclear. Two competing explanations have emerged in the literature: an early interaction model and a late interaction model. In the present study, we used visual conjunction search to test competing predictions from these 2 models. Participants searched for targets that were defined by a conjunction of physical and numerical size. Some distractors shared the target's physical size, and the remaining distractors shared the target's numerical size. We held the total number of search items fixed and manipulated the ratio of the 2 distractor set sizes. The results from 3 experiments converge on the conclusion that numerical magnitude is not a guiding feature for visual search, and that physical and numerical magnitude are processed independently, which supports a late interaction model of the size congruity effect.

Differential roles of right temporal cortex and Broca's area in pitch processing: evidence from music and Mandarin.

PubMed

Nan, Yun; Friederici, Angela D

2013-09-01

Superior temporal and inferior frontal cortices are involved in the processing of pitch information in the domain of language and music. Here, we used fMRI to test the particular roles of these brain regions in the neural implementation of pitch in music and in tone language (Mandarin) with a group of Mandarin speaking musicians whose pertaining experiences in pitch are similar across domains. Our findings demonstrate that the neural network for pitch processing includes the pars triangularis of Broca's area and the right superior temporal gyrus (STG) across domains. Within this network, pitch sensitive activation in Broca's area is tightly linked to the behavioral performance of pitch congruity judgment, thereby reflecting controlled processes. Activation in the right STG is independent of performance and more sensitive to pitch congruity in music than in tone language, suggesting a domain-specific modulation of the perceptual processes. These observations provide a first glimpse at the cortical pitch processing network shared across domains. Copyright © 2012 Wiley Periodicals, Inc., a Wiley company.

The contribution of sound intensity in vocal emotion perception: behavioral and electrophysiological evidence.

2012-01-01

Although its role is frequently stressed in acoustic profile for vocal emotion, sound intensity is frequently regarded as a control parameter in neurocognitive studies of vocal emotion, leaving its role and neural underpinnings unclear. To investigate these issues, we asked participants to rate the angry level of neutral and angry prosodies before and after sound intensity modification in Experiment 1, and recorded electroencephalogram (EEG) for mismatching emotional prosodies with and without sound intensity modification and for matching emotional prosodies while participants performed emotional feature or sound intensity congruity judgment in Experiment 2. It was found that sound intensity modification had significant effect on the rating of angry level for angry prosodies, but not for neutral ones. Moreover, mismatching emotional prosodies, relative to matching ones, induced enhanced N2/P3 complex and theta band synchronization irrespective of sound intensity modification and task demands. However, mismatching emotional prosodies with reduced sound intensity showed prolonged peak latency and decreased amplitude in N2/P3 complex and smaller theta band synchronization. These findings suggest that though it cannot categorically affect emotionality conveyed in emotional prosodies, sound intensity contributes to emotional significance quantitatively, implying that sound intensity should not simply be taken as a control parameter and its unique role needs to be specified in vocal emotion studies.

Multiplex congruity: Friendship networks and perceived popularity as correlates of adolescent alcohol use

Adolescents interact with their peers in multiple social settings and form various types of peer relationships that affect drinking behavior. Friendship and popularity perceptions constitute critical relationships during adolescence. These two relations are commonly measured by asking students to name their friends, and this network is used to construct drinking exposure and peer status variables. This study takes a multiplex network approach by examining the congruity between friendships and popularity as correlates of adolescent drinking. Using data on friendship and popularity nominations among high school adolescents in Los Angeles, California (N = 1707; five schools), we examined the associations between an adolescent's drinking and drinking by (a) their friends only; (b) multiplexed friendships, friends also perceived as popular; and (c) congruent, multiplexed-friends, close friends perceived as popular. Logistic regression results indicated that friend-only drinking, but not multiplexed-friend drinking, was significantly associated with self-drinking (AOR = 3.51, p < 0.05). However, congruent, multiplexed-friend drinking also was associated with self-drinking (AOR = 3.10, p < 0.05). This study provides insight into how adolescent health behavior is predicated on the multiplexed nature of peer relationships. The results have implications for the design of health promotion interventions for adolescent drinking. PMID:24913275

When closed manipulation fails to restore articular congruity in comminuted, displaced fractures of the distal radius, open reduction and internal fixation is required. Results of surgical stabilization and articular reconstruction of these injuries are reviewed in this retrospective study of 49 patients with 52 displaced, intra-articular distal radius fractures. Forty-three patients (87%) with a mean age of 37 years (range of 17 to 79 years) were available for evaluation. The mean follow-up time was 38 months (range 22-69 months). When rated according to the Association for the Study of Internal Fixation (ASIF), 19 were type C2 and 21 were type C3. We devised an Injury Score System based on the initial injury radiographs to classify severely comminuted intra-articular fractures and to identify those associated with carpal injury (3 patients). Post-operative fracture alignment, articular congruity, and radial length were significantly improved following surgery (p < .01). Grip strength averaged 69% +/- 22% of the contralateral side, and the range of motion averaged 75% +/- 18% of the contralateral side post-operatively. A combined outcome rating system that included grip strength, range of motion, and pain relief averaged 76% +/- 19% of the contralateral side. There was a statistically significant decrease in the combined rating with more severe fracture patterns as defined by the ASIF system (p < .01), Malone classification (p < .03), and the Injury Score System (p < .001). The Injury Score System presented here, and in particular the number of fracture fragments, correlated most closely with outcome of all the classification systems studied. Operative treatment of these distal radius fractures with reconstruction of the articular congruity and correction of the articular surface alignment with internal fixation and/or external fixation, can significantly improve the radiographic alignment and functional outcome. Furthermore, the degree to which articular stepoff, gap between fragments, and radial shortening are improved by surgery is strongly correlated with improved outcome, even when the results are corrected for severity of initial injury, whereas correction of radial tilt or dorsal tilt did not correlate with improved outcome.

Making meaningful worlds: role-playing subcultures and the autism spectrum.

PubMed

Fein, Elizabeth

2015-06-01

Every summer, a group of role-playing gamers gathers in an American town. Dressed up as moon goddesses, mad scientists, and other fantastical characters, they act out elaborate, improvised narratives of transformation, destruction, and redemption. For several summers, this group, who I call the Journeyfolk, ran a camp for teenagers on the autism spectrum, engaging campers in therapeutic reconfigurations of self and social role. Through this folk healing practice, the meaning of autism was itself transformed; what had been a source of isolation became a source of commonality and community. This paper takes the camp as a case study for examining the co-productive relationship between culture and neurodiversity. Cognitive tendencies often found in autism are often thought to preclude socio-cultural participation. However, such tendencies can also facilitate the co-creation of innovative cultural spaces, through processes of affinity and affiliation. Drawing on ethnographic fieldwork at the camp, I identify three sites of congruity between the culture of the camp and the cognitive and phenomenological experiences associated with autism, at which this "work of culture" (Obeysekere in The Work of Culture: Symbolic Transformation in Psychoanalysis and Anthropology, University of Chicago Press, Chicago, 1990) took place: the structure of social interactions within roleplaying games, the narratives enacted within these games, and the interpersonal relationships within which the games were embedded.

With regard to supination-external rotation type-IV (SER IV) ankle fractures, there is no consensus regarding which patient, injury, and treatment variables most strongly influence clinical outcome. The purpose of this investigation was to examine the impact of articular surface congruity on the functional outcomes of operatively treatment of SER IV ankle fractures. A prospectively generated database consisting of operatively treated SER IV ankle fractures was reviewed. Postoperative computed tomography (CT) scans were used to assess ankle joint congruity. Ankles were considered incongruent in the presence of >2 mm of articular step-off, intra-articular loose bodies, or an articular surface gap of >2 mm (despite an otherwise anatomic reduction) due to joint impaction and comminution. Patients with at least one year of clinical follow-up were eligible for analysis. The primary and secondary outcome measures were the Foot and Ankle Outcome Score (FAOS) and ankle motion. One hundred and eight SER IV fractures met our inclusion criteria. The average duration of follow-up was twenty-one months. Seventy-two patients (67%) had a congruent ankle joint, and thirty-six (33%) had elements of articular surface incongruity on postoperative CT scanning. These two groups were similar with regard to comorbidities and injury and treatment variables. At the time of the final follow-up, the group with articular incongruity had a significantly worse FAOS with regard to symptoms (p = 0.012), pain (p = 0.004), and activities of daily living (p = 0.038). Those with articular incongruity had worse average scores in the FAOS sport domain as well. No significant differences in ankle motion were found between the two groups. In this population of patients with an operatively treated SER IV ankle fracture, the presence of postoperative articular incongruity correlated with inferior early clinical outcomes. Orthopaedic surgeons should scrutinize ankle fracture reductions and strive for perfection to allow for the best possible clinical outcome. Therapeutic Level IV.

The Separate Spheres Model of Gendered Inequality.

Miller, Andrea L; Borgida, Eugene

2016-01-01

Research on role congruity theory and descriptive and prescriptive stereotypes has established that when men and women violate gender stereotypes by crossing spheres, with women pursuing career success and men contributing to domestic labor, they face backlash and economic penalties. Less is known, however, about the types of individuals who are most likely to engage in these forms of discrimination and the types of situations in which this is most likely to occur. We propose that psychological research will benefit from supplementing existing research approaches with an individual differences model of support for separate spheres for men and women. This model allows psychologists to examine individual differences in support for separate spheres as they interact with situational and contextual forces. The separate spheres ideology (SSI) has existed as a cultural idea for many years but has not been operationalized or modeled in social psychology. The Separate Spheres Model presents the SSI as a new psychological construct characterized by individual differences and a motivated system-justifying function, operationalizes the ideology with a new scale measure, and models the ideology as a predictor of some important gendered outcomes in society. As a first step toward developing the Separate Spheres Model, we develop a new measure of individuals' endorsement of the SSI and demonstrate its reliability, convergent validity, and incremental predictive validity. We provide support for the novel hypotheses that the SSI predicts attitudes regarding workplace flexibility accommodations, income distribution within families between male and female partners, distribution of labor between work and family spheres, and discriminatory workplace behaviors. Finally, we provide experimental support for the hypothesis that the SSI is a motivated, system-justifying ideology.

Interaction between numbers and size during visual search.

PubMed

Krause, Florian; Bekkering, Harold; Pratt, Jay; Lindemann, Oliver

2017-05-01

The current study investigates an interaction between numbers and physical size (i.e. size congruity) in visual search. In three experiments, participants had to detect a physically large (or small) target item among physically small (or large) distractors in a search task comprising single-digit numbers. The relative numerical size of the digits was varied, such that the target item was either among the numerically large or small numbers in the search display and the relation between numerical and physical size was either congruent or incongruent. Perceptual differences of the stimuli were controlled by a condition in which participants had to search for a differently coloured target item with the same physical size and by the usage of LCD-style numbers that were matched in visual similarity by shape transformations. The results of all three experiments consistently revealed that detecting a physically large target item is significantly faster when the numerical size of the target item is large as well (congruent), compared to when it is small (incongruent). This novel finding of a size congruity effect in visual search demonstrates an interaction between numerical and physical size in an experimental setting beyond typically used binary comparison tasks, and provides important new evidence for the notion of shared cognitive codes for numbers and sensorimotor magnitudes. Theoretical consequences for recent models on attention, magnitude representation and their interactions are discussed.

Memory for emotional words: The role of semantic relatedness, encoding task and affective valence.

Ferré, Pilar; Fraga, Isabel; Comesaña, Montserrat; Sánchez-Casas, Rosa

2015-01-01

Emotional stimuli have been repeatedly demonstrated to be better remembered than neutral ones. The aim of the present study was to test whether this advantage in memory is mainly produced by the affective content of the stimuli or it can be rather accounted for by factors such as semantic relatedness or type of encoding task. The valence of the stimuli (positive, negative and neutral words that could be either semantically related or unrelated) as well as the type of encoding task (focused on either familiarity or emotionality) was manipulated. The results revealed an advantage in memory for emotional words (either positive or negative) regardless of semantic relatedness. Importantly, this advantage was modulated by the encoding task, as it was reliable only in the task which focused on emotionality. These findings suggest that congruity with the dimension attended at encoding might contribute to the superiority in memory for emotional words, thus offering us a more complex picture of the underlying mechanisms behind the advantage for emotional information in memory.

A key theme in science education research concerns the decline in young peoples' interest in science and the need for professionals in hard science. Goal Congruity Theory posits that an important aspect of the decision whether to pursue hard science for study or as a career is the perception that hard science careers do not fulfil social (working with people) and societal (serving or helping others) interests. In this qualitative study, we explore grade 12 students' perceptions about the social and societal orientation of hard science careers. Furthermore, we investigate the variation in students' social and societal interests. Six focus groups were conducted with 58 grade 12 students in Flanders. Our results indicate that a number of students hold stereotypical views about hard science careers' social orientation, while others believe cooperation with others is an important aspect of hard science careers nowadays. Furthermore, our results show that students believe hard science careers can be societally oriented in the sense that they often associate them with innovation or societal progress. Finally, our results indicate that students may differentiate direct versus indirect societal orientation. These findings contribute to literature regarding social and societal interests and students' perceptions of hard science careers.

Motion is represented by low-level signals, such as size-expansion in vision or loudness changes in the auditory modality. The visual and auditory signals from the same object or event may be integrated and facilitate detection. We explored behavioural and electrophysiological correlates of congruent and incongruent audio-visual depth motion in conditions where auditory level changes, visual expansion, and visual disparity cues were manipulated. In Experiment 1 participants discriminated auditory motion direction whilst viewing looming or receding, 2D or 3D, visual stimuli. Responses were faster and more accurate for congruent than for incongruent audio-visual cues, and the congruency effect (i.e., difference between incongruent and congruent conditions) was larger for visual 3D cues compared to 2D cues. In Experiment 2, event-related potentials (ERPs) were collected during presentation of the 2D and 3D, looming and receding, audio-visual stimuli, while participants detected an infrequent deviant sound. Our main finding was that audio-visual congruity was affected by retinal disparity at an early processing stage (135-160ms) over occipito-parietal scalp. Topographic analyses suggested that similar brain networks were activated for the 2D and 3D congruity effects, but that cortical responses were stronger in the 3D condition. Differences between congruent and incongruent conditions were observed between 140-200ms, 220-280ms, and 350-500ms after stimulus onset. Copyright © 2015 Elsevier Ltd. All rights reserved.

Mechanobiology of the Meniscus

The meniscus plays a critical biomechanical role in the knee, providing load support, joint stability, and congruity. Importantly, growing evidence indicates that the mechanobiologic response of meniscal cells plays a critical role in the physiologic, pathologic, and repair responses of the meniscus. Here we review experimental and theoretical studies that have begun to directly measure the biomechanical effects of joint loading on the meniscus under physiologic and pathologic conditions, showing that the menisci are exposed to high contact stresses, resulting in a complex and nonuniform stress-strain environment within the tissue. By combining microscale measurements of the mechanical properties of meniscal cells and their pericellular and extracellular matrix regions, theoretical and experimental models indicate that the cells in the meniscus are exposed to a complex and inhomogeneous environment of stress, strain, fluid pressure, fluid flow, and a variety of physicochemical factors. Studies across a range of culture systems from isolated cells to tissues have revealed that the biological response of meniscal cells is directly influenced by physical factors, such as tension, compression, and hydrostatic pressure. In addition, these studies have provided new insights into the mechanotransduction mechanisms by which physical signals are converted into metabolic or pro/anti-inflammatory responses. Taken together, these in vivo and in vitro studies show that mechanical factors play an important role in the health, degeneration, and regeneration of the meniscus. A more thorough understanding of the mechanobiologic responses of the meniscus will hopefully lead to therapeutic approaches to prevent degeneration and enhance repair of the meniscus. PMID:25731738

In two experiments, we examined the impact of foveal semantic expectancy and congruity on parafoveal word processing during reading. Experiment 1 utilized an eye-tracking gaze contingent display change paradigm, and Experiment 2 measured event-related brain potentials (ERP) in a modified RSVP paradigm to track the time-course of foveal semantic influences on convert attentional allocation to parafoveal word processing. Furthermore, eye-tracking and ERP data converged to reveal graded effects of semantic foveal load on parafoveal processing.

According to the concept of embodied numerosity, bodily experiences influence the way in which we process numerical magnitude. The development of this influence could be anchored in the spatial ordering of numbers along a mental number line representation, which is measured by effects of spatial-numerical associations. The aim of this study was to investigate whether horizontally oriented full-body movement and visual presentation of a number line both contribute to spatial-numerical associations in children. We presented fourth-graders with 2 magnitude comparison tasks that differed in the relevance of magnitude information. In both tasks, we varied the amount of bodily movement in different response conditions (responding verbally, with a foot tap, or by jumping) and the visual presentation (items were presented with or without a number line). From the data, we calculated 2 spatial-numerical effects and expected to find the strongest effects if a full-body response was combined with a number line presentation. The 2 effects were differentially influenced by response modalities, but not presentation. The SNARC (= Spatial Numerical Association of Response Codes) effect was present in all conditions and was not influenced by our manipulations. In contrast, a new relative numerical congruity effect was influenced by the variations in responses in accordance with our hypotheses. The relative numerical congruity effect results suggest that responses involving bodily movement increase activation of spatial-numerical associations compared to verbal responses. These results are the first to demonstrate such an influence in a full-body approach in elementary schoolchildren. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Objective: To describe and apply a semiquantitative MRI scoring system for multifeature analysis of cartilage defect repair in the knee by osteochondral allografts and to correlate this scoring system with histopathologic, micro–computed tomography (µCT), and biomechanical reference standards using a goat repair model. Design: Fourteen adult goats had 2 osteochondral allografts implanted into each knee: one in the medial femoral condyle and one in the lateral trochlea. At 12 months, goats were euthanized and MRI was performed. Two blinded radiologists independently rated 9 primary features for each graft, including cartilage signal, fill, edge integration, surface congruity, calcified cartilage integrity, subchondral bone plate congruity, subchondral bone marrow signal, osseous integration, and presence of cystic changes. Four ancillary features of the joint were also evaluated, including opposing cartilage, meniscal tears, synovitis, and fat-pad scarring. Comparison was made with histologic and µCT reference standards as well as biomechanical measures. Interobserver agreement and agreement with reference standards was assessed. Cohen’s κ, Spearman’s correlation, and Kruskal-Wallis tests were used as appropriate. Results: There was substantial agreement (κ > 0.6, P < 0.001) for each MRI feature and with comparison against reference standards, except for cartilage edge integration (κ = 0.6). There was a strong positive correlation between MRI and reference standard scores (ρ = 0.86, P < 0.01). Osteochondral allograft MRI scoring system was sensitive to differences in outcomes between the types of allografts. Conclusions: We have described a comprehensive MRI scoring system for osteochondral allografts and have validated this scoring system with histopathologic and µCT reference standards as well as biomechanical indentation testing.

We studied 14 patients with well-characterized refractory temporal lobe epilepsy (TLE), 7 with right temporal lobe epilepsy (RTE) and 7 with left temporal lobe epilepsy (LTE), on a word repetition ERP experiment. Much prior literature supports the view that patients with left TLE are more likely to develop verbal memory deficits, often attributable to left hippocampal sclerosis. Our main objectives were to test if abnormalities of the N400 or Late Positive Component (LPC, P600) were associated with a left temporal seizure focus, or left temporal lobe dysfunction. A minimum of 19 channels of EEG/EOG data were collected while subjects performed a semantic categorization task. Auditory category statements were followed by a visual target word, which were 50% "congruous" (category exemplars) and 50% "incongruous" (non-category exemplars) with the preceding semantic context. These auditory-visual pairings were repeated pseudo-randomly at time intervals ranging from approximately 10-140 seconds later. The ERP data were submitted to repeated-measures ANOVAs, which showed the RTE group had generally normal effects of word repetition on the LPC and the N400. Also, the N400 component was larger to incongruous than congruous new words, as is normally the case. In contrast, the LTE group did not have statistically significant effects of either word repetition or congruity on their ERPs (N400 or LPC), suggesting that this ERP semantic categorization paradigm is sensitive to left temporal lobe dysfunction. Further studies are ongoing to determine if these ERP abnormalities predict hippocampal sclerosis on histopathology, or outcome after anterior temporal lobectomy.

A delta-rule model of numerical and non-numerical order processing.

Numerical and non-numerical order processing share empirical characteristics (distance effect and semantic congruity), but there are also important differences (in size effect and end effect). At the same time, models and theories of numerical and non-numerical order processing developed largely separately. Currently, we combine insights from 2 earlier models to integrate them in a common framework. We argue that the same learning principle underlies numerical and non-numerical orders, but that environmental features determine the empirical differences. Implications for current theories on order processing are pointed out. PsycINFO Database Record (c) 2014 APA, all rights reserved.

One debate in mathematical cognition centers on the single-representation model versus the two-representation model. Using an improved number Stroop paradigm (i.e., systematically manipulating physical size distance), in the present study we tested the predictions of the two models for number magnitude processing. The results supported the single-representation model and, more importantly, explained how a design problem (failure to manipulate physical size distance) and an analytical problem (failure to consider the interaction between congruity and task-irrelevant numerical distance) might have contributed to the evidence used to support the two-representation model. This study, therefore, can help settle the debate between the single-representation and two-representation models.

Coparental Affect, Children's Emotion Dysregulation, and Parent and Child Depressive Symptoms.

Children's emotion dysregulation and depressive symptoms are known to be affected by a range of individual (parent, child) and systemic (parent-child, marital, and family) characteristics. The current study builds on this literature by examining the unique role of coparental affect in children's emotion dysregulation, and whether this association mediates the link between parent and child depressive symptoms. Participants were 51 mother-father-child triads with children aged 7 to 12 (M age = 9.24 years). Triads discussed a time when the child felt sad and a time when the child felt happy. Maternal and paternal displays of positive affect were coded, and sequential analyses examined the extent to which parents were congruent in their displays of positive affect during the emotion discussions. Results indicated that interparental positive affect congruity (IPAC) during the sadness discussion, but not the happiness discussion, uniquely predicted parent-reported child emotion dysregulation, above and beyond the contributions of child negative affect and parental punitive reactions. The degree of IPAC during the sadness discussion and child emotion dysregulation mediated the association between maternal, but not paternal, depressive symptoms and child depressive symptoms. Findings highlight the unique role of coparental affect in the socialization of sadness in youth and offer initial support for low levels of IPAC as a risk factor for the transmission of depressive symptoms in youth. © 2015 Family Process Institute.

The purpose of this study was to determine the quality and re-operation rate of the surgical treatment of ankle fractures at a large university hospital. X-rays and patient records of 137 patients surgically treated for ankle fractures were analyzed for: 1) correct classification according to Lauge-Hansen, 2) if congruity of the ankle joint was achieved, 3) selection and placement of the hardware, and 4) the surgeon's level of education. Totally 32 of 137 did not receive an optimal treatment, 11 were re-operated. There was no clear correlation between incorrect operation and the surgeon's level of education.

Group Membership, Group Change, and Intergroup Attitudes: A Recategorization Model Based on Cognitive Consistency Principles.

PubMed

Roth, Jenny; Steffens, Melanie C; Vignoles, Vivian L

2018-01-01

The present article introduces a model based on cognitive consistency principles to predict how new identities become integrated into the self-concept, with consequences for intergroup attitudes. The model specifies four concepts (self-concept, stereotypes, identification, and group compatibility) as associative connections. The model builds on two cognitive principles, balance-congruity and imbalance-dissonance, to predict identification with social groups that people currently belong to, belonged to in the past, or newly belong to. More precisely, the model suggests that the relative strength of self-group associations (i.e., identification) depends in part on the (in)compatibility of the different social groups. Combining insights into cognitive representation of knowledge, intergroup bias, and explicit/implicit attitude change, we further derive predictions for intergroup attitudes. We suggest that intergroup attitudes alter depending on the relative associative strength between the social groups and the self, which in turn is determined by the (in)compatibility between social groups. This model unifies existing models on the integration of social identities into the self-concept by suggesting that basic cognitive mechanisms play an important role in facilitating or hindering identity integration and thus contribute to reducing or increasing intergroup bias.

Recent research has suggested that keeping track of a task goal in rapid task switching may depend on the phonological loop component of working memory. In this study, we investigated whether the phonological loop plays a similar role when a single switch extending over several trials is required after many trials on which one has performed a competing task. Participants were shown pairs of digits varying in numerical and physical size, and they were required to decide which digit was numerically or physically larger. An experimental cycle consisted of four blocks of 24 trials. In Experiment 1, participants in the task change groups performed the numerical-size judgment task during the first three blocks, and then changed to the physical-size judgment task in the fourth. Participants in the continuation groups performed only the physical-size judgment task throughout all four blocks. We found negative effects of articulatory suppression on the fourth block, but only in the task change groups. Experiment 2 was a replication, with the modification that both groups received identical instructions and practice. Experiment 3 was a further replication using numerical-size judgment as the target task. The results showed a pattern similar to that from Experiment 1, with negative effects of articulatory suppression found only in the task change group. The congruity of numerical and physical size had a reliable effect on performance in all three experiments, but unlike the task change, it did not reliably interact with articulatory suppression. The results suggest that in addition to its well-established role in rapid task switching, the phonological loop also contributes to active goal maintenance in longer-term action control.

Audit and feedback are recognized as part of a strategy for improving performance and supporting quality and safety in European health care systems. These considerations led the Clinical Management Staff of the "Regina Elena" Italian Cancer Institute to start a project of self-assessment of the quality of clinical records and organizational appropriateness through a retrospective review. The evaluation about appropriateness and congruity concerned both clinical records of 2013 and of 2015. At the end of the assessment of clinical records of each Care Unit, results were shared with medical staff in scheduled audit meetings. One hundred and thirteen clinical records (19%) did not meet congruity criteria, while 74 (12.6%) resulted as inappropriate. Considering the economic esteem calculated from the difference between Diagnosis Related Groups (DRG) primarily identified as main diagnosis and main surgical intervention or procedure and those modified during the Local Health Unit (LHU) assessment, 2 surgical Care Units produced a high negative difference in terms of economic value with a consequent drop of hospital discharge form (named in Italian "scheda di dimissione ospedaliera", SDO) remuneration, 7 Care Units produced about the same medium difference with almost no change as SDO remuneration, and 2 Care Units had a positive difference with a profit in terms of SDO remuneration. Concerning the quality assessment of clinical records of 2015, the most critical areas were related to medical documents and hospital discharge form compilation. Our experience showed the effectiveness of clinical audit in assessing the quality of filling in medical records and the appropriateness of hospital admissions and the acceptability of this tool by clinicians.

Tibial Plateau Fractures in Elderly Patients

Tibial plateau fractures are common in the elderly population following a low-energy mechanism. Initial evaluation includes an assessment of the soft tissues and surrounding ligaments. Most fractures involve articular depression leading to joint incongruity. Treatment of these fractures may be complicated by osteoporosis, osteoarthritis, and medical comorbidities. Optimal reconstruction should restore the mechanical axis, provide a stable construct for mobilization, and reestablish articular congruity. This is accomplished through a variety of internal or external fixation techniques or with acute arthroplasty. Regardless of the treatment modality, particular focus on preservation and maintenance of the soft tissue envelope is paramount. PMID:27551570

Management and organization research has traditionally focused on employees' work role and the interface between their work and family roles. We suggest that persons assume a third role in modern society that is relevant to work and organizations, namely the Information and Communication Technology User (ICTU) role. Based on role theory and boundary theory, we develop propositions about the characteristics of this role, as well as how ICTU role characteristics are related to boundary spanning activity, inter-role spillover with the work role, and work role performance. To this end, we first conceptualize the ICTU role and its associations with work and family roles. We then apply identity theory and boundary management theory to advance our understanding of how the ICTU role is related to criteria that are important to individuals and to organizations, namely self-selection into certain types of work roles and positive and negative inter-role spillover. The implications of this role for theory, research, and practice in management and organizations are discussed.

Symbolic and non-symbolic number magnitude processing in children with developmental dyscalculia.

2012-11-01

The aim of this study was to evaluate if children with Developmental Dyscalculia (DD) exhibit a general deficit in magnitude representations or a specific deficit in the connection of symbolic representations with the corresponding analogous magnitudes. DD was diagnosed using a timed arithmetic task. The experimental magnitude comparison tasks were presented in non-symbolic and symbolic formats. DD and typically developing (TD) children showed similar numerical distance and size congruity effects. However, DD children performed significantly slower in the symbolic task. These results are consistent with the access deficit hypothesis, according to which DD children's deficits are caused by difficulties accessing magnitude information from numerical symbols rather than in processing numerosities per se.

Osteochondral lesions are a common sports-related injury for which osteochondral grafting, including mosaicplasty, is an established treatment. Computer navigation has been gaining popularity in orthopaedic surgery to improve accuracy and precision. Navigation improves angle and depth matching during harvest and placement of osteochondral grafts compared with conventional freehand open technique. Controlled laboratory study. Three cadaveric knees were used. Reference markers were attached to the femur, tibia, and donor/recipient site guides. Fifteen osteochondral grafts were harvested and inserted into recipient sites with computer navigation, and 15 similar grafts were inserted freehand. The angles of graft removal and placement as well as surface congruity (graft depth) were calculated for each surgical group. The mean harvesting angle at the donor site using navigation was 4 degrees (standard deviation, 2.3 degrees ; range, 1 degrees -9 degrees ) versus 12 degrees (standard deviation, 5.5 degrees ; range, 5 degrees -24 degrees ) using freehand technique (P < .0001). The recipient plug removal angle using the navigated technique was 3.3 degrees (standard deviation, 2.1 degrees ; range, 0 degrees -9 degrees ) versus 10.7 degrees (standard deviation, 4.9 degrees ; range, 2 degrees -17 degrees ) in freehand (P < .0001). The mean navigated recipient plug placement angle was 3.6 degrees (standard deviation, 2.0 degrees ; range, 1 degrees -9 degrees ) versus 10.6 degrees (standard deviation, 4.4 degrees ; range, 3 degrees -17 degrees ) with freehand technique (P = .0001). The mean height of plug protrusion under navigation was 0.3 mm (standard deviation, 0.2 mm; range, 0-0.6 mm) versus 0.5 mm (standard deviation, 0.3 mm; range, 0.2-1.1 mm) using a freehand technique (P = .0034). Significantly greater accuracy and precision were observed in harvesting and placement of the osteochondral grafts in the navigated procedures. Clinical studies are needed to establish a benefit in vivo. Improvement in the osteochondral harvest and placement is desirable to optimize clinical outcomes. Navigation shows great potential to improve both harvest and placement precision and accuracy, thus optimizing ultimate surface congruity.

This study examined whether long-term abacus-based mental calculation (AMC) training improved numerical processing efficiency and at what stage of information processing the effect appeard. Thirty-three children participated in the study and were randomly assigned to two groups at primary school entry, matched for age, gender and IQ. All children went through the same curriculum except that the abacus group received a 2-h/per week AMC training, while the control group did traditional numerical practice for a similar amount of time. After a 2-year training, they were tested with a numerical Stroop task. Electroencephalographic (EEG) and event related potential (ERP) recording techniques were used to monitor the temporal dynamics during the task. Children were required to determine the numerical magnitude (NC) (NC task) or the physical size (PC task) of two numbers presented simultaneously. In the NC task, the AMC group showed faster response times but similar accuracy compared to the control group. In the PC task, the two groups exhibited the same speed and accuracy. The saliency of numerical information relative to physical information was greater in AMC group. With regards to ERP results, the AMC group displayed congruity effects both in the earlier (N1) and later (N2 and LPC (late positive component) time domain, while the control group only displayed congruity effects for LPC. In the left parietal region, LPC amplitudes were larger for the AMC than the control group. Individual differences for LPC amplitudes over left parietal area showed a positive correlation with RTs in the NC task in both congruent and neutral conditions. After controlling for the N2 amplitude, this correlation also became significant in the incongruent condition. Our results suggest that AMC training can strengthen the relationship between symbolic representation and numerical magnitude so that numerical information processing becomes quicker and automatic in AMC children.

Elastic Coulomb breakup of 34Na

NASA Astrophysics Data System (ADS)

Singh, G.; Shubhchintak, Chatterjee, R.

2016-08-01

Background: 34Na is conjectured to play an important role in the production of seed nuclei in the alternate r -process paths involving light neutron rich nuclei very near the β -stability line, and as such, it is important to know its ground state properties and structure to calculate rates of the reactions it might be involved in, in the stellar plasma. Found in the region of `island of inversion', its ground state might not be in agreement with normal shell model predictions. Purpose: The aim of this paper is to study the elastic Coulomb breakup of 34Na on 208Pb to give us a core of 33Na with a neutron and in the process we try and investigate the one neutron separation energy and the ground state configuration of 34Na. Method: A fully quantum mechanical Coulomb breakup theory within the architecture of post-form finite range distorted wave Born approximation extended to include the effects of deformation is used to research the elastic Coulomb breakup of 34Na on 208Pb at 100 MeV/u. The triple differential cross section calculated for the breakup is integrated over the desired components to find the total cross-section, momentum, and angular distributions as well as the average momenta, along with the energy-angular distributions. Results: The total one neutron removal cross section is calculated to test the possible ground state configurations of 34Na. The average momentum results along with energy-angular calculations indicate 34Na to have a halo structure. The parallel momentum distributions with narrow full widths at half-maxima signify the same. Conclusion: We have attempted to analyze the possible ground state configurations of 34Na and in congruity with the patterns in the `island of inversion' conclude that even without deformation, 34Na should be a neutron halo with a predominant contribution to its ground state most probably coming from 33Na(3 /2+)⊗ 2 p3 /2ν configuration. We also surmise that it would certainly be useful and rewarding to test our predictions with an experiment to put stricter limits on its ground state configuration and binding energy.

Deliberate and emergent strategies for implementing person-centred care: a qualitative interview study with researchers, professionals and patients.

The introduction of innovative models of healthcare does not necessarily mean that they become embedded in everyday clinical practice. This study has two aims: first, to analyse deliberate and emergent strategies adopted by healthcare professionals to overcome barriers to normalization of a specific framework of person-centred care (PCC); and secondly, to explore how the recipients of PCC understand these strategies. This paper is based on a qualitative study of the implementation of PCC in a Swedish context. It draws on semi-structured interviews with 18 researchers and 17 practitioners who adopted a model of PCC on four different wards and 20 patients who were cared for in one of these wards. Data from these interviews were first coded inductively and emerging themes are analysed in relation to normalization process theory (NPT). In addition to deliberate strategies, we identify emergent strategies to normalize PCC by (i) creating and sustaining coherence in small but continuously communicating groups (ii) interpreting PCC flexibly when it meets specific local situations and (iii) enforcing teamwork between professional groups. These strategies resulted in patients perceiving PCC as bringing about (i) a sense of ease (ii) appreciation of inter-professional congruity (ii) non-hierarchical communication. NPT is useful to identify and analyse deliberate and emergent strategies relating to mechanisms of normalization. Emergent strategies should be interpreted not as trivial solutions to problems in implementation, but as a possible repertoire of tools, practices and skills developed in situ. As professionals and patients may have different understandings of implementation, it is also crucial to include patients' perceptions to evaluate outcomes.

This study aims to evaluate whether volar locking plate was superior over non-locking plate in the treatment of die-punch fractures of the distal radius. A total of 57 patients with closed die-punch fractures of the distal radius were included and analyzed. Of them, 32 were treated by non-locking plate (NLP) and the remaining 25 were treated by volar locking plate (VLP). Preoperative radiographs, computer tomographs and three-dimensional reconstruction, radiographs taken at immediate postoperation and at last follow-up were extracted and evaluated. Patients' electronic medical records were inquired and related demographic and medical data were documented. The documented contents were volar tilt, radial inclination, ulnar variance, grip strength, Disabilities of the Arm, Shoulder, and Hand (DASH) and visual analog scale (VAS) scores and complications. VLP group demonstrated a significantly reduced radial subsidence of 1.5 mm (0.7 versus 2.2 mm), during the interval of bony union (P < 0.001), compared to NLP group. Larger proportion of patients (88% versus 62.5%) in VLP group gained acceptable joint congruity (step-off <2 mm) at the final follow-up (P = 0.037). No significant differences were observed between the groups in the measurements of volar tilt, radial inclination, DASH, VAS and grip strength recovery at the last follow-up. There was a trend of fewer overall complications (5/25 versus 10/32) and major complications that required surgery interventions (1/25 versus 4/32) in VLP than NLP groups, although the difference did not approach to significance (P = 0.339, 0.372). VLP leaded to significantly better results of reduction maintainance and the final joint congruity than NLP, while reducing overall and major complications. However, the results should be treated in the context of limitations and the clinical significance of the difference required further studies to investigate.

The role of theory in qualitative health research.

PubMed

Kelly, Moira

2010-06-01

The role of theory in qualitative research is often underplayed but it is relevant to the quality of such research in three main ways. Theory influences research design, including decisions about what to research and the development of research questions. Theory underpins methodology and has implications for how data are analyzed and interpreted. Finally, theory about a particular health issue may be developed, contributing to what is already known about the topic that is the focus of the study. This paper will critically consider the role of theory in qualitative primary care research in relation to these three areas. Different approaches to qualitative research will be drawn upon in order to illustrate the ways in which theory might variably inform qualitative research, namely generic qualitative research, grounded theory and discourse analysis. The aim is to describe and discuss key issues and provide practical guidance so that researchers are more aware of the role theory has to play and the importance of being explicit about how theory affects design, analysis and the quality of qualitative research.

Role theory: a framework to investigate the community nurse role in contemporary health care systems.

PubMed

Brookes, Kim; Davidson, Patricia M; Daly, John; Halcomb, Elizabeth J

2007-01-01

Nurses' perceptions of their role are influenced by societal attitudes, government policies and trends in professional issues. Dynamic factors in contemporary health environments challenge traditional nursing roles, in particular those of community nurses. Role theory is a conceptual framework that defines how individuals behave in social situations and how these behaviours are perceived by external observers. This paper reviews the role theory literature as a conceptual framework to explore community nurses' perceptions of their role. Three theoretical perspectives of role theory have emerged from the literature review: 1. social structuralism 2. symbolic interactionism and 3. the dramaturgical perspective. These philosophical perspectives provide a useful framework to investigate the role of community nurses in the contemporary health care system.

How face blurring affects body language processing of static gestures in women and men.

PubMed

Proverbio, A M; Ornaghi, L; Gabaro, V

2018-05-14

The role of facial coding in body language comprehension was investigated by ERP recordings in 31 participants viewing 800 photographs of gestures (iconic, deictic and emblematic), which could be congruent or incongruent with their caption. Facial information was obscured by blurring in half of the stimuli. The task consisted of evaluating picture/caption congruence. Quicker response times were observed in women than in men to congruent stimuli, and a cost for incongruent vs. congruent stimuli was found only in men. Face obscuration did not affect accuracy in women as reflected by omission percentages, nor reduced their cognitive potentials, thus suggesting a better comprehension of face deprived pantomimes. N170 response (modulated by congruity and face presence) peaked later in men than in women. Late Positivity was much larger for congruent stimuli in the female brain, regardless of face blurring. Face presence specifically activated the right superior temporal and fusiform gyri, cingulate cortex and insula, according to source reconstruction. These regions have been reported to be insufficiently activated in face-avoiding individuals with social deficits. Overall, the results corroborate the hypothesis that females might be more resistant to the lack of facial information or better at understanding body language in face-deprived social information.

Role-exit theory and marital discord following extended military deployment.

PubMed

Gambardella, Lucille C

2008-07-01

The purpose of this study was to determine the effectiveness of applying role-exit theory concepts in the counseling of military couples experiencing marital discord following extended periods of deployment. Qualitative case-study methodology was utilized to assess, diagnose, and treat 10 military couples using a framework based on role-exit theory. Six couples self-reported improvement in the marital relationship following this counseling approach. Role-exit theory based counseling may benefit other couples who experience marital discord due to role issues. The clinical nurse specialist might consider this paradigm when working with couples in marital therapy.

The inadequacy of role models for educating medical students in ethics with some reflections on virtue theory.

PubMed

Erde, E L

1997-01-01

Persons concerned with medical education sometimes argued that medical students need no formal education in ethics. They contended that if admissions were restricted to persons of good character and those students were exposed to good role models, the ethics of medicine would take care of itself. However, no one seems to give much philosophic attention to the ideas of model or role model. In this essay, I undertake such an analysis and add an analysis of role. I show the weakness in relying on role models exclusively and draw implications from these for appeals to virtue theory. Furthermore, I indicate some of the problems about how virtue theory is invoked as the ethical theory that would most closely be associated to the role model rhetoric and consider some of the problems with virtue theory. Although Socrates was interested in the character of the (young) persons with whom he spoke, Socratic education is much more than what role modeling and virtue theory endorse. It-that is, philosophy-is invaluable for ethics education.

Van Driest transformation and compressible wall-bounded flows

Huang, P. G.; Coleman, G. N.

1994-01-01

The transformation validity question utilizing resulting data from direct numerical simulations (DNS) of supersonic, isothermal cold wall channel flow was investigated. The DNS results stood for a wide scope of parameter and were suitable for the purpose of examining the generality of Van Driest transformation. The Van Driest law of the wall can be obtained from the inner-layer similarity arguments. It was demonstrated that the Van Driest transformation cannot be incorporated to collapse the sublayer and log-layer velocity profiles simultaneously. Velocity and temperature predictions according to the preceding composite mixing-length model were presented. Despite satisfactory congruity with the DNS data, the model must be perceived as an engineering guide and not as a rigorous analysis.

This study examined the neural correlates of intentional and automatic number processing (indexed by number comparison and physical Stroop task, respectively) in 6- and 7-year-old children born prematurely. Behavioral results revealed significant numerical distance and size congruity effects. Imaging results disclosed (1) largely overlapping fronto-parietal activation for intentional and automatic number processing, (2) a frontal to parietal shift of activation upon considering the risk factors gestational age and birth weight, and (3) a task-specific link between math proficiency and functional magnetic resonance imaging (fMRI) signal within distinct regions of the parietal lobes—indicating commonalities but also specificities of intentional and automatic number processing.

Utilitarian and deontological ethics in medicine.

Mandal, Jharna; Ponnambath, Dinoop Korol; Parija, Subhash Chandra

2016-01-01

Medical ethics is a sensible branch of moral philosophy and deals with conflicts in obligations/duties and their potential outcome. Two strands of thought exist in ethics regarding decision-making: deontological and utilitarian. In deontological approach, outcomes/consequences may not just justify the means to achieve it while in utilitarian approach; outcomes determine the means and greatest benefit expected for the greatest number. In brief, deontology is patient-centered, whereas utilitarianism is society-centered. Although these approaches contradict each other, each of them has their own substantiating advantages and disadvantages in medical practice. Over years, a trend has been observed from deontological practice to utilitarian approach leading to frustration and discontentment. Health care system and practitioners need to balance both these ethical arms to bring congruity in medical practice.

Recruitment and retention of psychosocial rehabilitation workers.

PubMed

Blankertz, L E; Robinson, S E

1997-01-01

Recruitment and retention of direct service workers can be a major problem for administrators of community mental health organizations. This paper, based on a nationwide study of psychosocial rehabilitation workers and administrators, examines the congruity of worker and administrator perceptions of worker motivation for entering and leaving the field. Workers are motivated by the intrinsic nature of the work to enter into and stay in the field. Job burnout is as important as low pay in forcing workers out of the field. Administrators, however, perceive money to be a major factor motivating workers to enter the field and perceive external opportunities as forces that pull them away. Thus, administrators must address their workers' needs if their agencies are to offer quality services.

Functional improvement has become one of the aims of the treatment of bipolar disorder. However, scant attention has been given to family functioning, even though it has a role in the illness outcome and is affected by the disorder. The aims of this study were to compare family functioning reported by euthymic patients with bipolar disorder and healthy controls; explore the level of congruence in the perception of family environment between patients with bipolar disorder and their relatives; and analyse the relationship between clinical variables and family functioning. The sample comprised 82 adult euthymic subjects with bipolar disorder, 82 family caregivers of these patients and 47 healthy controls. Participants completed the Family Environment Scale. Results showed moderate correlations and a mean pattern almost identical between relatives' and patients' reported scores in family functioning subscales. There were significant differences between patients and controls, favourable for the latter, in the subscales cohesion (p<0.005), expressiveness (p=0.002), conflict (p=0.038), intellectual-cultural orientation (p=0.001), active-recreational orientation (p<0.005), and a non-significant trend in organization (p=0.064). Significant associations were found between family environment and clinical variables of severity. These findings contribute to increasing the understanding of family functioning in bipolar disorder and highlight the importance of family work. Copyright © 2016 Elsevier Ireland Ltd.

We study the role of the pressure in the partial regularity theory for weak solutions of the Navier-Stokes equations. By introducing the notion of dissipative solutions, due to D uchon and R obert (Nonlinearity 13:249-255, 2000), we will provide a generalization of the Caffarelli, Kohn and Nirenberg theory. Our approach sheels new light on the role of the pressure in this theory in connection to Serrin's local regularity criterion.

Utilizing role theory to help employed parents cope with children's chronic illness.

PubMed

Major, Debra A

2003-02-01

Role theory is utilized to detail a six-step process for developing balanced coping through role negotiation. As applied in this paper, the role theory framework provides health educators with a useful tool for helping employed parents cope with a child's chronic illness. The emphasis is on partnering with parents or primary caregivers to identify, understand and manage the multiple role demands of working parents with chronically ill children. Role theory suggests ways health educators can support balanced coping by educating families about the demands of a child's illness, and helping to reduce those demands, helping to increase family resources, supporting parents and facilitating role negotiation. The ultimate goal is the development of balanced coping strategies that (1) meet the medical and emotional needs of the ill child, (2) allow parents to maintain their physical and mental health, and (3) enable parents to meet the demands of their other roles (e.g. paid employment).

Theory of mind, the ability to understand mental states, involves inferences about others' cognitive (cognitive theory of mind) and emotional (affective theory of mind) mental states. The current study explored the role of executive functions in developing affective theory of mind across adolescence. Affective theory of mind and three subcomponents of executive functions (inhibition, updating, and shifting) were measured. Affective theory of mind was positively related to age, and all three executive functions. Specifically, inhibition explained the largest amount of variance in age-related differences in affective theory of mind.

The effects of socioeconomic incongruity in the neighbourhood on social support, self-esteem and mental health in England.

2014-06-01

Analyses of neighbourhood socioeconomic characteristics and health indicators consistently show that health is worse in poorer neighbourhoods. However, some studies that examined neighbourhood effects separately for individuals of different socioeconomic position found that poor people may derive health benefits from living in poor neighbourhoods where they are socioeconomically congruous. This study investigates whether such patterns may be driven by psychosocial factors. The sample consisted of 4871 mothers in the Millennium Cohort Study aged 14-53. The outcomes analysed were neighbourhood friendship, emotional support, self-esteem and depression or anxiety. Neighbourhood status was classified by residents' educational and occupational status derived from the 2001 Census. We used multilevel logistic regression, adjusting for mothers' socio-demographic characteristics: first analysing health by neighbourhood status separately for the highest and lowest status mothers, then testing for modification in the association between neighbourhood status and health, by individual status. Results show that for highest status mothers, living in mixed or high status neighbourhoods compared to low status neighbourhoods significantly reduced the odds of having no friends in the neighbourhood by 65%. Living in high status neighbourhoods compared to low status neighbourhoods also significantly reduced the odds of depression or anxiety for highest status mothers by 41%. No associations were found for emotional support or self-esteem amongst highest status mothers. No associations were found for any outcome among lowest status mothers. In conclusion, low status mothers in England did not have better social support, self-esteem, or mental health when living in low status neighbourhoods compared to high status neighbourhoods; any benefits of socioeconomic congruity may have been counteracted by neighbourhood deprivation. Nevertheless, we found that mothers of high status do have significantly better neighbourhood friendship and mental health when living in socioeconomic congruity within neighbourhoods. Whether these associations are causal or are another reflection of material advantage remains unclear. Copyright © 2014 Elsevier Ltd. All rights reserved.

We evaluate the effect of reconstructing huge defects (mean, 15.8 cm) of the distal femur with Ilizarov's distraction osteogenesis and free twin-barreled vascularized fibular bone graft (TVFG). We retrospectively reviewed a consecutive series of five patients who had cases of distal femoral fractures with huge defects and infection that were treated by the Ilizarov's distraction osteogenesis. After radical debridement, two of the five cases had free TVFG and monolocal distraction osteogenesis, and another two cases had multilocal distraction osteogenesis with knee fusion because of loss of the joint congruity. The other case with floating knee injury had bilocal distraction osteogenesis and a preserved knee joint. The mean defect of distal femur was 15.8 cm (range, 14-18 cm) in length. The mean length of distraction osteogenesis by Ilizarov's apparatus was 8.2 cm. The mean length of TVFG was 8 cm. The average duration from application of Ilizarov's apparatus to achievement of bony union was 10.2 months (range, 8-13 months). At the end of the follow-up, ranges of motion of three knees were 0 to 45 degrees, 0 to 60 degrees, and 0 to 90 degrees. Two cases had knee arthrodesis with bony fusion because of loss of the joint congruity. There were no leg length discrepancies in all five patients. In addition, three patients had pin tract infections and one case had a 10 degree varus deformity of the femur. Juxta-articular huge defect (>10 cm) of distal femur remains a challenge to orthopedic surgeons. Ilizarov's technique provides the capability to maintain stability, eradicate infection, restore leg length, and to perform adjuvant reconstructive procedure easily. In this study, we found that combining Ilizarov's distraction osteogenesis with TVFG results in improved patient outcome for patients with injuries such as supracondylar or intercondylar infected fractures or nonunion of distal femur with huge bone defect.

Emancipatory Nursing Praxis: A Theory of Social Justice in Nursing.

PubMed

Walter, Robin R

Emancipatory nursing praxis (ENP) is a middle-range nursing theory of social justice developed from an international, grounded theory study of the critical factors influencing nurses' perceptions of their role in social justice. The ENPs implementing processes (becoming, awakening, engaging, and transforming) and 2 conditional contexts (relational and reflexive) provide an in-depth understanding of the transformative learning process that determines nurse engagement in social justice. Interpretive findings include the voice of Privilege primarily informed ENP theory, the lack of nursing educational and organizational support in social justice role development, and the advocate role should expand to include the role of an ally.

A confluence of contexts: asymmetric versus global failures of selective attention to stroop dimensions.

PubMed

Sabri, M; Melara, R D; Algom, D

2001-06-01

In 6 experiments probing selective attention through Stroop classification, 4 factors of context were manipulated: (a) psychophysical context, the distinctiveness of values along the color and word dimensions; (b) set size context, the number of stimulus values tested; (c) production context, the mode used to respond; and (d) covariate context, the correlation between the dimensions. The psychophysical and production contexts mainly caused an asymmetry in selective attention failure between colors and words, whereas the set size and covariate contexts contributed primarily to the average or global magnitudes of attentional disruption across dimensions. The results suggest that (a) Stroop dimensions are perceptually separable, (b) J.R. Stroop's (1935) classic findings arose from his particular combination of contexts, and (c) stimulus uncertainty and dimensional imbalance are the primary sources of task and congruity effects in the Stroop paradigm.

Lifting and lowering theory is one of the important basis for guiding clinical medication. Through the study of ancient books and literature, we learned that lifting and lowering theory was originated in Huangdi Neijing, practiced more in the Shanghan Zabing Lun, established in Yixue Qiyuan, and developed in Compendium of Materia Medica and now. However, lifting and lowering theory is now mostly stagnated in the theoretical stage, with few experimental research. In the clinical study, the guiding role of lifting and lowering theory to prescriptions?mainly includes opposite?role?of lift and lower medicine property, mutual promotion of lift and lower medicine property, main role of lift medicine property and main role of lower medicine property. Under the guidance of lifting and lowering theory, the herb pair compatibility include herb combination of lift medicine property, herb combination of lift and lower medicine property and herb combination of lower medicine property. Modern biological technology was used in this study to carry out experimental research on the lifting and lowering theory, revealing the scientific connotation of it, which will help to promote clinical rational drug use.

On Dreams and Motivation: Comparison of Freud's and Hobson's Views.

PubMed

Boag, Simon

2016-01-01

The merits of Freudian dream theory continue to be debated and both supporters and critics appeal to empirical evidence to support their respective positions. What receives much less attention is the theoretical coherency of either Freudian dream theory or alternative perspectives. This paper examines Freudian dream theory and J. Allan Hobson's alternative position by addressing the role of motivation in dreams. This paper first discusses motivation in Freudian theory and its relation to dreams and disguise-censorship. The role of motivation in Hobson's theory is then considered. Hobson's claim that dream plot and content selection is random and based on design error and functional imbalance is then discussed in relation to the protoconsciousness theory proposal that dreams serve an adaptive function. While there are apparent inconsistencies in Hobson's position, his appeal to emotions and instincts provides a preliminary platform for understanding the role of motivation in dreams that is consonant with the Freudian position.

Subliminal number priming within and across the visual and auditory modalities.

PubMed

Kouider, Sid; Dehaene, Stanislas

2009-01-01

Whether masked number priming involves a low-level sensorimotor route or an amodal semantic level of processing remains highly debated. Several alternative interpretations have been put forward, proposing either that masked number priming is solely a byproduct of practice with numbers, or that stimulus awareness was underestimated. In a series of four experiments, we studied whether repetition and congruity priming for numbers reliably extend to novel (i.e., unpracticed) stimuli and whether priming transfers from a visual prime to an auditory target, even when carefully controlling for stimulus awareness. While we consistently observed cross-modal priming, the generalization to novel stimuli was weaker and reached significance only when considering the whole set of experiments. We conclude that number priming does involve an amodal, semantic level of processing, but is also modulated by task settings.

Attitude-behavior congruity, mindfulness, and self-focused attention: A behavior-analytic reconstruction

PubMed Central

Street, Warren R.

1994-01-01

Social psychologists have responded to research reporting low agreement between attitude measures and related behavior with attempts to explain the incongruities and enhance agreement. This article examines attitude-behavior incongruity from a behavior-analytic point of view. Traditional and behavior-analytic views of attitudes and behaviors are compared. In the behavior-analytic view, answering an attitude scale should be considered as behavior displayed by a person under rather unusual social conditions, not as a reflection of an enduring personal disposition. Reasons why questionnaire-answering behavior will not resemble behavior in other functionally different social conditions are reviewed. Special attention is extended to two representative lines of attitude-behavior research: mindfulness and self-focused attention. Discriminative stimuli in both areas of study have produced more predictable agreement between questionnaire-answering behavior and behavior in other settings. PMID:22478180

Hip, Knee, and Ankle Osteoarthritis Negatively Affects Mechanical Energy Exchange.

PubMed

Queen, Robin M; Sparling, Tawnee L; Schmitt, Daniel

2016-09-01

Individuals with osteoarthritis (OA) of the lower limb find normal locomotion tiring compared with individuals without OA, possibly because OA of any lower limb joint changes limb mechanics and may disrupt transfer of potential and kinetic energy of the center of mass during walking, resulting in increased locomotor costs. Although recovery has been explored in asymptomatic individuals and in some patient populations, the effect of changes in these gait parameters on center of mass movements and mechanical work in patients with OA in specific joints has not been well examined. The results can be used to inform clinical interventions and rehabilitation that focus on improving energy recovery. We hypothesized that (1) individuals with end-stage lower extremity OA would exhibit a decrease in walking velocity compared with asymptomatic individuals and that the joint affected with OA would differntially influence walking velocity, (2) individuals with end-stage lower extremity OA would show decreased energy recovery compared with asymptomatic individuals and that individuals with end-stage hip and ankle OA would have greater reductions in recovery than would individuals with end-stage knee OA owing to restrictions in hip and ankle motion, and (3) that differences in the amplitude and congruity of the center of mass would explain the differences in energy recovery that are observed in each population. Ground reaction forces at a range of self-selected walking speeds were collected from individuals with end-stage radiographic hip OA (n = 27; 14 males, 13 females; average age, 55.6 years; range, 41-70 years), knee OA (n = 20; seven males, 13 females; average age, 61.7 years; range, 49-74 years), ankle OA (n = 30; 14 males, 16 females; average age, 57 years; range, 45-70 years), and asymptomatic individuals (n = 13; eight males, five females; average age, 49.8 years; range, 41-67 years). Participants were all patients with end-stage OA who were scheduled to have joint replacement surgery within 4 weeks of testing. All patients were identified by the orthopaedic surgeon as having end-stage radiographic disease and to be a candidate for joint replacement surgery. Patients were excluded if they had pain at any other lower extremity joint, previous joint replacement surgery, or needed to use an assistive device for ambulation. Patients were enrolled if they met the study inclusion criteria. Our study was comparative and cohorts could be compared with each other, however, the asymptomatic group served to verify our methods and provided a recovery standard with which we could compare our patients. Potential and kinetic energy relationships (% congruity) and energy exchange (% recovery) were calculated. Linear regressions were used to examine the effect of congruity and amplitude of energy fluctuations and walking velocity on % recovery. Analysis of covariance was used to compare energy recovery between groups. The results of this study support our hypothesis that individuals with OA walk at a slower velocity than asymptomatic individuals (1.4 ± 0.2 m/second, 1.2-1.5 m/second) and that the joint affected by OA also affects walking velocity (p < 0.0001). The cohort with ankle OA (0.9 ± 0.2 m/second, 0.77-0.94 m/second) walked at a slower speed relative to the cohort with hip OA (1.1 ± 0.2 m/second, 0.96-1.1 m/second; p = 0.002). However, when comparing the cohorts with ankle and knee OA (0.9 ± 0.2 m/second, 0.77-0.94 m/second) there was no difference in walking speed (p = 0.16) and the same was true when comparing the cohorts with knee and hip OA (p = 0.14). Differences in energy recovery existed when comparing the OA cohorts with the asymptomatic cohort and when examining differences between the OA cohorts. After adjusting for walking speeds these results showed that asymptomatic individuals (65% ± 3%, 63%-67%) had greater recovery than individuals with hip OA (54% ± 10%, 50%-58%; p = 0.014) and ankle OA (47% ± 13%, 40%-52%; p = 0.002) but were not different compared with individuals with knee OA (57% ± 10%, 53%-62%; p = 0.762). When speed was accounted for, 80% of the variation in recovery not attributable to speed was explained by congruity with only 10% being explained by amplitude. OA in the hip, knee, or ankle reduces effective exchange of potential and kinetic energy, potentially increasing the muscular work required to control movements of the center of mass. The fatigue and limited physical activity reported in patients with lower extremity OA could be associated with increased mechanical work of the center of mass. Focused gait retraining potentially could improve walking mechanics and decrease fatigue in these patients.

Fostering good citizenship through ethical leadership: exploring the moderating role of gender and organizational politics.

PubMed

Kacmar, K Michele; Bachrach, Daniel G; Harris, Kenneth J; Zivnuska, Suzanne

2011-05-01

Considering the implications of social exchange theory as a context for social role behavior, we tested relations between ethical leadership and both person- and task-focused organizational citizenship behavior and examined the roles played by employee gender and politics perceptions. Although social exchange theory predicts that ethical leadership is positively associated with citizenship, social role theory predicts that the nature of this relationship may vary on the basis of gender and politics perceptions. Results from data collected from 288 supervisor-subordinate dyads indicate that the pattern of male versus female employees' citizenship associated with ethical leadership depends significantly on their perceptions of politics. Implications for theory and practice are discussed.

The investigation of vehicle safety needs for older drivers and passengers is integral for their safe transportation. A program of research on safe transportation for seniors was launched through AUTO21, a Canadian Network of Centres of Excellence. This national research network focuses on a wide range of automotive issues, from materials and design to safety and societal issues. An inductive qualitative inquiry of seniors' driving experiences, safety feature use, and strategies to prevent injury and manage risks was a first step in this program. We conducted interviews and focus groups with 58 seniors without disabilities and 9 seniors with disabilities. We identified a lack of congruity between the vehicle and safety feature design and seniors' needs. Seniors described strategies to manage their safety and that of others. Specific aspects of vehicle design, safety features, and action strategies that support safer use and operation of a vehicle by seniors are outlined.

Categorising intersectional targets: An "either/and" approach to race- and gender-emotion congruity.

PubMed

Smith, Jacqueline S; LaFrance, Marianne; Dovidio, John F

2017-01-01

Research on the interaction of emotional expressions with social category cues in face processing has focused on whether specific emotions are associated with single-category identities, thus overlooking the influence of intersectional identities. Instead, we examined how quickly people categorise intersectional targets by their race, gender, or emotional expression. In Experiment 1, participants categorised Black and White faces displaying angry, happy, or neutral expressions by either race or gender. Emotion influenced responses to men versus women only when gender was made salient by the task. Similarly, emotion influenced responses to Black versus White targets only when participants categorised by race. In Experiment 2, participants categorised faces by emotion so that neither category was more salient. As predicted, responses to Black women differed from those to both Black men and White women. Thus, examining race and gender separately is insufficient to understanding how emotion and social category cues are processed.

Automatic numerical-spatial association in synaesthesia: An fMRI investigation.

PubMed

Arend, Isabel; Ashkenazi, Sarit; Yuen, Kenneth; Ofir, Shiran; Henik, Avishai

2017-01-27

A horizontal mental number line (MNL) is used to describe how quantities are represented across space. In humans, the neural correlates associated with such a representation are found in different areas of the posterior parietal cortex, especially, the intraparietal sulcus (IPS). In a phenomenon known as number-space synaesthesia, individuals visualise numbers in specific spatial locations. The experience of a MNL for number-space synaesthetes is explicit, idiosyncratic, and highly stable over time. It remains an open question whether the mechanisms underlying numerical-spatial association are shared by synaesthetes and nonsynaesthetes. We address the neural correlates of number-space association by examining the brain response in a number-space synaestheste (MkM) whose MNL differs dramatically in its ordinality and direction from that of a control group. MkM and 15 nonsynaesthetes compared the physical size of two numbers, while ignoring their numerical value, during an event-related functional magnetic resonance imaging session (fMRI). Two factors were analysed: the numerical distance effect (NDE; e.g., 2-4 small distance vs. 1-6 large distance), and the size congruity effect (e.g., 2-8 congruent vs. 2-8 incongruent). Only for MkM, the NDE elicited significant activity in the left and right IPS, supramarginal gyrus (bilateral), and in the left angular gyrus. These results strongly support the role of the parietal cortex in the automatic coding of space and quantity in number-space synaesthesia, even when numerical values are task-irrelevant.

Intra- Versus Intersex Aggression: Testing Theories of Sex Differences Using Aggression Networks.

PubMed

Wölfer, Ralf; Hewstone, Miles

2015-08-01

Two theories offer competing explanations of sex differences in aggressive behavior: sexual-selection theory and social-role theory. While each theory has specific strengths and limitations depending on the victim's sex, research hardly differentiates between intrasex and intersex aggression. In the present study, 11,307 students (mean age = 14.96 years; 50% girls, 50% boys) from 597 school classes provided social-network data (aggression and friendship networks) as well as physical (body mass index) and psychosocial (gender and masculinity norms) information. Aggression networks were used to disentangle intra- and intersex aggression, whereas their class-aggregated sex differences were analyzed using contextual predictors derived from sexual-selection and social-role theories. As expected, results revealed that sexual-selection theory predicted male-biased sex differences in intrasex aggression, whereas social-role theory predicted male-biased sex differences in intersex aggression. Findings suggest the value of explaining sex differences separately for intra- and intersex aggression with a dual-theory framework covering both evolutionary and normative components. © The Author(s) 2015.

On Dreams and Motivation: Comparison of Freud’s and Hobson’s Views

PubMed Central

Boag, Simon

2017-01-01

The merits of Freudian dream theory continue to be debated and both supporters and critics appeal to empirical evidence to support their respective positions. What receives much less attention is the theoretical coherency of either Freudian dream theory or alternative perspectives. This paper examines Freudian dream theory and J. Allan Hobson’s alternative position by addressing the role of motivation in dreams. This paper first discusses motivation in Freudian theory and its relation to dreams and disguise-censorship. The role of motivation in Hobson’s theory is then considered. Hobson’s claim that dream plot and content selection is random and based on design error and functional imbalance is then discussed in relation to the protoconsciousness theory proposal that dreams serve an adaptive function. While there are apparent inconsistencies in Hobson’s position, his appeal to emotions and instincts provides a preliminary platform for understanding the role of motivation in dreams that is consonant with the Freudian position.

Reconciling professional identity: A grounded theory of nurse academics' role modelling for undergraduate students.

PubMed

Baldwin, A; Mills, J; Birks, M; Budden, L

2017-12-01

Role modelling by experienced nurses, including nurse academics, is a key factor in the process of preparing undergraduate nursing students for practice, and may contribute to longevity in the workforce. A grounded theory study was undertaken to investigate the phenomenon of nurse academics' role modelling for undergraduate students. The study sought to answer the research question: how do nurse academics role model positive professional behaviours for undergraduate students? The aims of this study were to: theorise a process of nurse academic role modelling for undergraduate students; describe the elements that support positive role modelling by nurse academics; and explain the factors that influence the implementation of academic role modelling. The study sample included five second year nursing students and sixteen nurse academics from Australia and the United Kingdom. Data was collected from observation, focus groups and individual interviews. This study found that in order for nurse academics to role model professional behaviours for nursing students, they must reconcile their own professional identity. This paper introduces the theory of reconciling professional identity and discusses the three categories that comprise the theory, creating a context for learning, creating a context for authentic rehearsal and mirroring identity.

Clinical outcome measurement: Models, theory, psychometrics and practice.

PubMed

McClimans, Leah; Browne, John; Cano, Stefan

In the last decade much has been made of the role that models play in the epistemology of measurement. Specifically, philosophers have been interested in the role of models in producing measurement outcomes. This discussion has proceeded largely within the context of the physical sciences, with notable exceptions considering measurement in economics. However, models also play a central role in the methods used to develop instruments that purport to quantify psychological phenomena. These methods fall under the umbrella term 'psychometrics'. In this paper, we focus on Clinical Outcome Assessments (COAs) and discuss two measurement theories and their associated models: Classical Test Theory (CTT) and Rasch Measurement Theory. We argue that models have an important role to play in coordinating theoretical terms with empirical content, but to do so they must serve: 1) as a representation of the measurement interaction; and 2) in conjunction with a theory of the attribute in which we are interested. We conclude that Rasch Measurement Theory is a more promising approach than CTT in these regards despite the latter's popularity with health outcomes researchers. Copyright © 2017.

Incorporating political socialization theory into baccalaureate nursing education.

PubMed

Brown, S G

1996-01-01

Political socialization theory explains how an individual develops a political belief system. As the health care system undergoes dramatic changes, nursing faculty should use political socialization theory to enhance the education of student nurses. A political thread can be woven through the nursing curricula, and students can be socialized to the political role. The new generation of nurses must incorporate a political component into their professional role identity. Political socialization theory can guide nursing faculty as knowledge of the political system and political skills are incorporated into nursing curricula.

Emotion and Theory of Mind in Schizophrenia-Investigating the Role of the Cerebellum.

PubMed

Mothersill, Omar; Knee-Zaska, Charlotte; Donohoe, Gary

2016-06-01

Social cognitive dysfunction, including deficits in facial emotion recognition and theory of mind, is a core feature of schizophrenia and more strongly predicts functional outcome than neurocognition alone. Although traditionally considered to play an important role in motor coordination, the cerebellum has been suggested to play a role in emotion processing and theory of mind, and also shows structural and functional abnormalities in schizophrenia. The aim of this systematic review was to investigate the specific role of the cerebellum in emotion and theory of mind deficits in schizophrenia using previously published functional neuroimaging studies. PubMed and PsycINFO were used to search for all functional neuroimaging studies reporting altered cerebellum activity in schizophrenia patients during emotion processing or theory of mind tasks, published until December 2014. Overall, 14 functional neuroimaging studies were retrieved. Most emotion studies reported lower cerebellum activity in schizophrenia patients relative to healthy controls. In contrast, the theory of mind studies reported mixed findings. Altered activity was observed across several posterior cerebellar regions involved in emotion and cognition. Weaker cerebellum activity in schizophrenia patients relative to healthy controls during emotion processing may contribute to blunted affect and reduced ability to recognise emotion in others. This research could be expanded by examining the relationship between cerebellum function, symptomatology and behaviour, and examining cerebellum functional connectivity in patients during emotion and theory of mind tasks.

Schizophrenia patients experience impairments across various functional roles. Emotional unresponsiveness and an inability to foster intimacy and display affection may lead to impairments in parenting. A comprehensive cognitive understanding of parenting abilities in schizophrenia has the potential to guide newer treatment strategies. As part of a larger study on functional ability in schizophrenia patients, we attempted a cognitive deconstruction of their parenting ability. Sixty-nine of the 170 patients who participated in a study on social cognition in remitted schizophrenia were parents (mean age of their children: 11.8 ± 6.2 years). They underwent comprehensive assessments for neurocognition, social cognition (theory of mind, emotion processing, social perception and attributional bias), motivation and insight. A rater blind to their cognitive status assessed their social functioning using the Groningen Social Disabilities Schedule. We examined the association of their functional ability (active involvement and affective relationship) in the parental role with their cognitive performance as well as with their level of insight and motivation. Deficits in first- and second-order theory of mind (t = 2.57, p = 0.01; t = 3.2, p = 0.002, respectively), speed of processing (t = 2.37, p = 0.02), cognitive flexibility (t = 2.26, p = 0.02) and motivation (t = 2.64, p = 0.01) had significant association with parental role dysfunction. On logistic regression, second-order theory of mind emerged as a specific predictor of parental role, even after controlling for overall functioning scores sans parental role. Second-order theory of mind deficits are specifically associated with parental role dysfunction of patients with schizophrenia. Novel treatment strategies targeting theory of mind may improve parenting abilities in individuals with schizophrenia.

The role of tumor board conferences in neuro-oncology: a nationwide provider survey.

2017-05-01

The tumor board or multidisciplinary cancer meeting (MCM) is the foundation of high value multidisciplinary oncology care, coordinating teams of specialists. Little is known on how these meetings are implemented in Neuro-oncology. Benefits of MCMs include coordination, direction for complicated cases, education, and a forum for communication, emerging technology, and clinical trials. This study identifies participation and utilization of neuro-oncology MCMs. A cross-sectional descriptive survey was dispersed through an internet questionnaire. The Society of Neuro-Oncology and the American Brain Tumor Association provided a list of dedicated neuro-oncology centers. All National Cancer Institute designated centers, and participants in the Adult Brain Tumor Consortium or the Brain Tumor Trials Collaborative were included, identifying 85 centers. Discussion included primary brain tumors (100%), challenging cases (98%), recurrent disease (96%), neoplastic spine disease (93%), metastatic brain lesions (89%), pre-surgical cases (82%), pathology (76%), and paraneoplastic disease (40%). MCMs were composed of neuro-oncologists, neurosurgeons, and radiation oncologists (100%), radiologists (98%), pathologists (96%), and clinical trial participants (64%). Individual preparation ranged from 15 to 300 min. MCMs were valued for clinical decision making (94%), education (89%), and access to clinical trials (69%). 13% documented MCMs in the medical record. 38% of centers used a molecular tumor board; however, many commented with uncertainty as to how this is defined. Neuro-oncology MCMs at leading U.S. institutions demonstrate congruity of core disciplines, cases discussed, and perceived value. We identified variability in preparation time and implementation of MCM recommendations. There is high uncertainty as to the definition and application of a molecular tumor board.

Seeking congruity between goals and roles: a new look at why women opt out of science, technology, engineering, and mathematics careers.

PubMed

Diekman, Amanda B; Brown, Elizabeth R; Johnston, Amanda M; Clark, Emily K

2010-08-01

Although women have nearly attained equality with men in several formerly male-dominated fields, they remain underrepresented in the fields of science, technology, engineering, and mathematics (STEM). We argue that one important reason for this discrepancy is that STEM careers are perceived as less likely than careers in other fields to fulfill communal goals (e.g., working with or helping other people). Such perceptions might disproportionately affect women's career decisions, because women tend to endorse communal goals more than men. As predicted, we found that STEM careers, relative to other careers, were perceived to impede communal goals. Moreover, communal-goal endorsement negatively predicted interest in STEM careers, even when controlling for past experience and self-efficacy in science and mathematics. Understanding how communal goals influence people's interest in STEM fields thus provides a new perspective on the issue of women's representation in STEM careers.

The theory and the therapeutic procedure of classical psychodrama are described along with brief illustrations. Classical psychodrama and sociodrama stemmed from role theory, enactments, "tele," the reciprocity of choices, and the theory of spontaneity-robopathy and creativity. The discussion focuses on key concepts such as the therapeutic team, the structure of the session, transference and reality, countertransference, the here-and-now and the encounter, the group-as-a-whole, resistance and difficult clients, and affect and cognition. Also described are the neoclassical approaches of psychodrama, action methods, and clinical role playing, and the significance of the concept of behavioral simulation in group psychotherapy.

Theory, the Final Frontier? A Corpus-Based Analysis of the Role of Theory in Psychological Articles

PubMed Central

Beller, Sieghard; Bender, Andrea

2017-01-01

Contemporary psychology regards itself as an empirical science, at least in most of its subfields. Theory building and development are often considered critical to the sciences, but the extent to which psychology can be cast in this way is under debate. According to those advocating a strong role of theory, studies should be designed to test hypotheses derived from theories (theory-driven) and ideally should yield findings that stimulate hypothesis formation and theory building (theory-generating). The alternative position values empirical findings over theories as the lasting legacy of science. To investigate which role theory actually plays in current research practice, we analyse references to theory in the complete set of 2,046 articles accepted for publication in Frontiers of Psychology in 2015. This sample of articles, while not representative in the strictest sense, covers a broad range of sub-disciplines, both basic and applied, and a broad range of article types, including research articles, reviews, hypothesis & theory, and commentaries. For the titles, keyword lists, and abstracts in this sample, we conducted a text search for terms related to empiricism and theory, assessed the frequency and scope of usage for six theory-related terms, and analyzed their distribution over different article types and subsections of the journal. The results indicate substantially lower frequencies of theoretical than empirical terms, with references to a specific (named) theory in less than 10% of the sample and references to any of even the most frequently mentioned theories in less than 0.5% of the sample. In conclusion, we discuss possible limitations of our study and the prospect of theoretical advancement. PMID:28642728

To investigate which role theory actually plays in current research practice, we analyse references to theory in the complete set of 2,046 articles accepted for publication in Frontiers of Psychology in 2015. This sample of articles, while not representative in the strictest sense, covers a broad range of sub-disciplines, both basic and applied, and a broad range of article types, including research articles, reviews, hypothesis & theory, and commentaries. For the titles, keyword lists, and abstracts in this sample, we conducted a text search for terms related to empiricism and theory, assessed the frequency and scope of usage for six theory-related terms, and analyzed their distribution over different article types and subsections of the journal. The results indicate substantially lower frequencies of theoretical than empirical terms, with references to a specific (named) theory in less than 10% of the sample and references to any of even the most frequently mentioned theories in less than 0.5% of the sample. In conclusion, we discuss possible limitations of our study and the prospect of theoretical advancement.

Geomorphology as science: the role of theory

NASA Astrophysics Data System (ADS)

Rhoads, Bruce L.; Thorn, Colin E.

1993-04-01

Because geomorphology is a science, it is permeated by theory. Overt recognition of this actuality is frequently resisted by geomorphologists. Earth history does not represent an alternative to earth science, it is an essential component of earth science. In its broadest sense science seeks to discover new knowledge through a two-stage activity involving the creation and justification of ideas (theory). Deduction is generally regarded as the only logically-consistent method of justifying ideas. The creation of ideas is a much more controversial topic. Some methodologists deem it beyond logic; certainly deductive arguments, which are nothing more than formal, logical expressions of theory, play no role in the conception of new ideas. Many earth scientists generate possible explanations of observed phenomena based on abductive reasoning. Others advocate reliance on purported forms of "pure" induction, such as serendipity and intuition, in which observations assume primacy over theory. Besides lacking consistency and educability, the latter posture is flawed because it mistakenly implies that becoming well-versed in theory is irrelevant to or impedes scientific discovery. Irrational or subjective factors play a role in the creation of ideas, but it is erroneous to claim that these factors are divorced from theory. Science is first and foremost a cognitive activity; thus, the primacy of observations in science is a myth. All observations are theory-laden in the sense that the act of observation inherently involves interpretation and classification, both of which can only occur within the context of theoretical preconceptions. Even discoveries based on unexpected observations require the fortunate investigator to recognize the theoretical importance of what is seen or measured. The most useful view of geomorphology as a science is one in which theory is seen as central, but fragile, and in which theory and observation are viewed symbiotically with theory providing the generative force and observation providing a vital policing role. Much of the current debate in geomorphology centers around differences in characteristics of theory, type of scientific arguments, and metaphysical perspectives among investigators working at different temporal scales. Full recognition and understanding of these differences are essential for developing a unified approach to the science of geomorphology.

Mechanisms through which reciprocal filial values protect wellbeing of Chinese adult-child caregivers in the US.

In this study, we explored the role of reciprocal filial values in protecting the wellbeing of Chinese adult-child caregivers in the US. Using survey data obtained from 137 Chinese adult-child caregivers living in seven US cities, we tested a latent variable model using structural equation modeling. In this model, informed by role theory, social exchange theory and stress-coping theory, reciprocal filial values affect caregiver wellbeing in the face of caregiver role strain, both directly and indirectly through protective effects of role rewards and coping. In the final model, reciprocal filial values had both direct and indirect protective effects on caregivers' wellbeing, offering evidence to address culturally sensitive issues in family caregivers with similar filial values. © 2014 Wiley Periodicals, Inc.

Not just numeracy and literacy: Theory of mind development and school readiness among low-income children.

PubMed

Cavadel, Elizabeth Woodburn; Frye, Douglas A

2017-12-01

The current study investigated the role of theory of mind development in school readiness among 120 low-income preschool and kindergarten children. A short-term longitudinal design was used to examine relations among theory of mind, the understanding of teaching, and learning behaviors and their collective role in children's literacy and numeracy skills at school entry. Results replicate differences in theory of mind development among low-income children as compared to typically studied, higher-income samples. Theory of mind and the combination of several sociocognitive variables successfully predicted concurrent relations with academic outcomes. Children's understanding of teaching predicted changes in literacy scores over time. Results are discussed in the context of what is known about theory of mind and sociocognitive development in school readiness. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

ASSESSING AND COMBINING RELIABILITY OF PROTEIN INTERACTION SOURCES

PubMed Central

LEACH, SONIA; GABOW, AARON; HUNTER, LAWRENCE; GOLDBERG, DEBRA S.

2008-01-01

Integrating diverse sources of interaction information to create protein networks requires strategies sensitive to differences in accuracy and coverage of each source. Previous integration approaches calculate reliabilities of protein interaction information sources based on congruity to a designated ‘gold standard.’ In this paper, we provide a comparison of the two most popular existing approaches and propose a novel alternative for assessing reliabilities which does not require a gold standard. We identify a new method for combining the resultant reliabilities and compare it against an existing method. Further, we propose an extrinsic approach to evaluation of reliability estimates, considering their influence on the downstream tasks of inferring protein function and learning regulatory networks from expression data. Results using this evaluation method show 1) our method for reliability estimation is an attractive alternative to those requiring a gold standard and 2) the new method for combining reliabilities is less sensitive to noise in reliability assignments than the similar existing technique.

Towards an alternative to Benner's theory of expert intuition in nursing: a discussion paper.

PubMed

Gobet, Fernand; Chassy, Philippe

2008-01-01

Several authors have highlighted the role of intuition in expertise. In particular, a large amount of data has been collected about intuition in expert nursing, and intuition plays an important role in the influential theory of nursing expertise developed by Benner [1984. From Novice to Expert: Excellence and Power in Clinical Nursing Practice. Addison-Wesley, Menlo Park, CA]. We discuss this theory, and highlight both data that support it and data that challenge it. Based on this assessment, we propose a new theory of nursing expertise and intuition, which emphasizes how perception and conscious problem solving are intimately related. In the discussion, we propose that this theory opens new avenues of enquiry for research into nursing expertise.

Developing a theory of the strategic core of teams: a role composition model of team performance.

PubMed

Humphrey, Stephen E; Morgeson, Frederick P; Mannor, Michael J

2009-01-01

Although numerous models of team performance have been articulated over the past 20 years, these models have primarily focused on the individual attribute approach to team composition. The authors utilized a role composition approach, which investigates how the characteristics of a set of role holders impact team effectiveness, to develop a theory of the strategic core of teams. Their theory suggests that certain team roles are most important for team performance and that the characteristics of the role holders in the "core" of the team are more important for overall team performance. This theory was tested in 778 teams drawn from 29 years of major league baseball (1974'-2002). Results demonstrate that although high levels of experience and job-related skill are important predictors of team performance, the relationships between these constructs and team performance are significantly stronger when the characteristics are possessed by core role holders (as opposed to non-core role holders). Further, teams that invest more of their financial resources in these core roles are able to leverage such investments into significantly improved performance. These results have implications for team composition models, as they suggest a new method for considering individual contributions to a team's success that shifts the focus onto core roles.

Psychotherapy: theory, experience, and personalized actuarial tables.

PubMed

Leventhal, D B; Shemberg, K M

1977-12-01

This paper addresses the issue of the role of theory in the actual application of psychotherapeutic operations. Within the present framework, psychotherapeutic effectiveness is seen as an empirical, actuarial process which occurs in an interpersonal setting separate from theoretical considerations. The role of theory is discussed and a rationale for the coexistence of equally 'effective' contradictory theories is presented. Suggestions for future research in the area of behaviour change are made and an argument for the eventual development of a 'therapeutic cookbook' is presented.

Moral Severity is Represented as a Domain-General Magnitude.

PubMed

Powell, Derek; Horne, Zachary

2017-03-01

The severity of moral violations can vary by degree. For instance, although both are immoral, murder is a more severe violation than lying. Though this point is well established in Ethics and the law, relatively little research has been directed at examining how moral severity is represented psychologically. Most prominent moral psychological theories are aimed at explaining first-order moral judgments and are silent on second-order metaethical judgments, such as comparisons of severity. Here, the relative severity of 20 moral violations was established in a preliminary study. Then, a second group of participants were asked to decide which of two moral violations was more severe for all possible combinations of these 20 violations. Participant's response times exhibited two signatures of domain-general magnitude comparisons: we observed both a distance effect and a semantic congruity effect. These findings suggest that moral severity is represented in a similar fashion as other continuous magnitudes.

Emergency department and 'Google flu trends' data as syndromic surveillance indicators for seasonal influenza.

PubMed

Thompson, L H; Malik, M T; Gumel, A; Strome, T; Mahmud, S M

2014-11-01

We evaluated syndromic indicators of influenza disease activity developed using emergency department (ED) data - total ED visits attributed to influenza-like illness (ILI) ('ED ILI volume') and percentage of visits attributed to ILI ('ED ILI percent') - and Google flu trends (GFT) data (ILI cases/100 000 physician visits). Congruity and correlation among these indicators and between these indicators and weekly count of laboratory-confirmed influenza in Manitoba was assessed graphically using linear regression models. Both ED and GFT data performed well as syndromic indicators of influenza activity, and were highly correlated with each other in real time. The strongest correlations between virological data and ED ILI volume and ED ILI percent, respectively, were 0·77 and 0·71. The strongest correlation of GFT was 0·74. Seasonal influenza activity may be effectively monitored using ED and GFT data.

Anti-Streptococcus IgM Antibodies Induce Repetitive Stereotyped Movements: Cell Activation and Co-Localization with Fcα/μ Receptors in the Striatum and Motor Cortex

PubMed Central

Zhang, Danhui; Patel, Ankur; Zhu, Youhua; Siegel, Allan; Zalcman, Steven S.

2012-01-01

Group A beta-hemolytic streptococcus (GABHS) infections are implicated in neuropsychiatric disorders associated with an increased expression of repetitive stereotyped movements. Anti-streptococcus IgG presumably cross-reacts with elements on basal ganglia cells, modifies their function, and triggers symptoms. IgM may play a unique role in precipitating behavioral disturbances since variations in cortico-striatal activity occur in temporal congruity with peak IgM titers during an orchestrated immune response. We discovered in Balb/c mice that single subcutaneous injections of mouse monoclonal IgM antibodies to Streptococcus Group A bacteria induce marked dose-dependent increases in repetitive stereotyped movements, including head bobbing, sniffing, and intense grooming. Effects were antibody- and antigen-specific: anti-streptococcus IgG stimulated ambulatory activity and vertical activity but not these stereotypies, while anti-KLH IgM reduced activity. We suggest that anti-streptococcus IgM and IgG play unique roles in provoking GABHS-related behavioral disturbances. Paralleling its stereotypy-inducing effects, anti-streptococcus IgM stimulated Fos-like immunoreactivity in regions linked to cortico-striatal projections involved in motor control, including subregions of the caudate, nucleus accumbens, and motor cortex. This is the first evidence that anti-streptococcus IgM antibodies induce in vivo functional changes in these structures. Moreover, there was a striking similarity in the distributions of anti-streptococcus IgM deposits and Fos-like immunoreactivity in these regions. Of further importance, Fcα/μ receptors, which bind IgM, were present- and co-localized with anti-streptococcus IgM in these structures. We suggest that anti-streptococcus IgM-induced alterations of cell activity reflect local actions of IgM that involve Fcα/μ receptors. These findings support the use of anti-streptococcus monoclonal antibody administration in Balb/c mice to model GABHS-related behavioral disturbances and identify underlying mechanisms.

The development and nature of femoral head cam lesions following acetabular fractures.

PubMed

Berber, Onur; Foote, Julian; Sabharwal, Sanjeeve; Datta, Gorav; Bircher, Martin D

2014-01-01

The aim of acetabular fracture fixation is to restore joint congruity with restoration of the articular surface. Poor outcomes are seen where this has not been achieved. Letournel reported a collarette osteophyte seen postoperatively in a proportion of patients, which he suggested was an early precursor to the development of osteoarthritis. This is a retrospective study of patients treated at a tertiary referral unit who developed this lesion. The triangular index was measured in 48 of these patients and then correlated with their clinical findings, Oxford Hip Score and the presence of osteoarthritis. Length of follow-up, fracture classification, and joint congruency were also recorded. Results showed a statistically significant relationship between cam lesion size and the development of osteoarthritis (P = 0.008), cam lesion size and length of follow-up (P = 0.01), and between groin pain and postoperative joint congruency (LR = 0.035). These findings suggest that the appearance of a cam lesion is a poor long-term prognostic marker for the development of osteoarthritis in patients with an acetabular fracture.

A Multilevel Assessment of Barriers to Adoption of Dietary Approaches to Stop Hypertension (DASH) among African Americans of Low Socioeconomic Status

PubMed Central

Bertoni, Alain G.; Foy, Capri G.; Hunter, Jaimie C.; Quandt, Sara A.; Vitolins, Mara Z.; Whitt-Glover, Melicia C.

2013-01-01

Background We examined perceptions of Dietary Approaches to Stop Hypertension (DASH) and the food environment among African Americans (AA) with high blood pressure living in two low-income communities and objectively assessed local food outlets. Methods Focus groups were conducted with 30 AAs; participants discussed DASH and the availability of healthy foods in their community. Sessions were transcribed and themes identified. Fifty-four stores and 114 restaurants were assessed using the Nutrition Environment Measures Survey (NEMS). Results Common themes included poor availability, quality, and cost of healthy foods; tension between following DASH and feeding other family members; and lack of congruity between their preferred foods and DASH. Food outlets in majority AA census tracts had lower NEMS scores (stores: −11.7, p=.01, restaurants: −8.3, p=.001) compared with majority White areas. Conclusions Interventions promoting DASH among lower income AAs should reflect the food customs, economic concerns, and food available in communities. PMID:22080704

Investigation on microstructure and mechanical properties of Mo2FeB2 based cermets with and without PVA

NASA Astrophysics Data System (ADS)

Shen, Yupeng; Huang, Zhifu; Jian, Yongxin; Yang, Ming; Li, Kemin

2018-03-01

Mo2FeB2 based cermets with and without PVA have been investigated by x-ray diffractometry (XRD), x-ray photoelectron spectroscope (XPS) and scanning electron microscopy (SEM). The density and transverse rupture strength (TRS) of green compact, relative density, hardness (HRA), fracture toughness (KIC) and TRS of Mo2FeB2 based cermets were also measured. The results indicate that, compared with the Mo2FeB2 based cermets without PVA, the density of green compact with PVA can be improved slightly at the same pressure. However, the much higher TRS is obtained for the green compact without PVA. Meanwhile, Mo2FeB2 particles exhibit the finer and less congruity feature for Mo2FeB2 based cermets without PVA. In addition, the higher relative density, hardness, fracture toughness and TRS can be acquired for the cermets without PVA. Obviously, considering the mechanical properties and preparation period of Mo2FeB2 based cermets, no adding PVA is the optimized process of powder molding in the manufacture of Mo2FeB2 based cermets.

Flexible and inflexible response components: a Stroop study with typewritten output.

PubMed

Damian, Markus F; Freeman, Norman H

2008-05-01

Two experiments were directed at investigating the relationship between response selection and execution in typewriting, and specifically the extent to which concurrent processing takes place. In a Stroop paradigm adapted from [Logan, G. D., & Zbrodoff, N. J. (1998). Stroop-type interference: Congruity effects in colour naming with typewritten responses. Journal of Experimental Psychology: Human Perception and Performance, 24, 978-992], participants typed the names of colour patches with incongruent, congruent, or neutral distractors presented at various stimulus-onset asynchronies. Experiment 1 showed Stroop interference and facilitation for initial keystroke latencies and errors, contrasting with response durations (a measure of response execution) being unaffected by Stroop manipulation. Experiment 2 showed that all three measures were responsive to time pressure; again, Stroop effects were confined to latencies and errors only. The observation that response duration is both flexible under time pressure and protected from response competition, may imply either that response execution is structurally segregated from earlier processing stages, or that encapsulation develops during the acquisition of typing skills.

The Role of Theory and Modeling in the International Living with a Star Program

NASA Technical Reports Server (NTRS)

Hesse, M.

2004-01-01

Today, theory and modeling play a critical role in our quest to understand the connection between solar eruptive phenomena, and their impacts in interplanetary space and in the near-Earth space environment. This new role is based on two developments, one related to the goal of basic physical understanding, and the other to space weather-related applications. When targeting physical our focus is shifting away from investigations aiming at basic discoveries, to missions and studies that address our basic understanding of processes we know to be important. For these studies, theory and models provide physical explanations that need to be verified or falsified by empirical evidence. Within this paradigm, a much more tight integration between theory modeling, and space flight mission design and execution is not only beneficial, but essential. One of the prime objectives of space weather research, on the other hand, is the prediction of space environmental conditions for the benefit of humans and their assets in near-Earth space and on the ground, as well as on solar system bodies like Mars that are of interest to exploration by humans. By its very nature, prediction requires modeling, which, in turn, requires understanding. We will present an overview of the role of theory and modeling within the International Living With a Star program. Specifically, we will focus on an assessment of present-day and future capabilities, as well as on strategies for tight integration of theory and modeling in space science investigations.

Henri Wallon's Theory of Early Child Development: The Role of Emotions

PubMed

Veer

1996-12-01

The present paper gives an account of part of the stage theory of early child development of the French theorist Henri Wallon (1879-1962). Unlike his contemporary Jean Piaget, Wallon concentrated his efforts upon a description of the child's emotional development and the role emotions play in establishing the bond between child and caregiver. The description of Wallon's stage theory is preceded by biographical information and a presentation of his methodological views. It is argued that Wallon's theory is unique in its focus, exerted influence upon theorists such as Lev Vygotsky, and is basically compatible with modern insights about the nature of child development and the growth of intersubjectivity.

Role of environmental variability in the evolution of life history strategies.

PubMed

Hastings, A; Caswell, H

1979-09-01

We reexamine the role of environmental variability in the evolution of life history strategies. We show that normally distributed deviations in the quality of the environment should lead to normally distributed deviations in the logarithm of year-to-year survival probabilities, which leads to interesting consequences for the evolution of annual and perennial strategies and reproductive effort. We also examine the effects of using differing criteria to determine the outcome of selection. Some predictions of previous theory are reversed, allowing distinctions between r and K theory and a theory based on variability. However, these distinctions require information about both the environment and the selection process not required by current theory.

The aim of psychoanalysis in theory and in practice.

PubMed

Steiner, J

1996-12-01

The aims of psychoanalysis are reviewed in terms of theories of mental function and structure. The theory of mental conflict remains the central theory of classical psychoanalysis but has been deepened and supplemented by newer theories. In particular the theory of projective identification has radically altered our view of mental structure and function and has allowed us to reformulate the aims of psychoanalysis in terms of the re-acquisition and re-integration of projected parts of the self. The central role of mourning in this process is discussed, and some of the obstacles to progress are reviewed. It is suggested that oedipal resentments may play a central role in the creation of impasse.

Madagascar nursing needs assessment: education and development of the profession.

PubMed

Plager, K A; Razaonandrianina, J O

2009-03-01

To address how Madagascar is improving nursing education and the profession to strengthen their nursing workforce. The sub-Saharan Africa nursing workforce shortage is more than 600,000. Madagascar measures among affected countries. Nursing in Madagascar with reference to the Malagasy Lutheran Church Health Department (SALFA) is examined in this paper. The Malagasy Lutheran Nursing School (SEFAM) was established in 1956 to prepare nurses and midwives. The school recently relocated to better meet SALFA goals to increase nurses in the system and improve nursing education. A US nursing faculty and the SEFAM director proposed to conduct programme assessment to ensure that nursing and midwifery education meet health, social and community needs in Madagascar. DATA SOURCE/METHODS: An in-depth needs assessment of the school programme, facilities and resources occurred. Site visits and informal interviews were held. Field study visits to nursing schools and health-care facilities in Kenya and Tanzania assisted the authors in learning how nursing developed in those countries. Data analysis included comparison of the authors' comprehensive notes for congruity and accuracy. Strategies are needed to support and maintain quality education, improve quality and quantity of nursing care services in hospitals and dispensaries, and improve conditions for nurses and other health-care workers. Compared with Madagascar, Kenya and Tanzania have more well-developed systems of nursing education and professional development. There were limited written sources for some information but methods, such as verbal accounts, compensated for this limitation. Implications include advantages, disadvantages, facilitators and barriers to nursing educational and professional development in Madagascar. Development of nursing education, regulation and the profession will continue with support from key stakeholders. Kenya and Tanzania can serve as role models for Madagascar nurses. Countries with similar nursing education and professional development issues can be informed by lessons learned in this project.

Del Boca, Frances K; Darkes, Jack; Goldman, Mark S; Smith, Gregory T

2002-06-01

Four papers from a 2001 Research Society on Alcoholism symposium on expectancy theory and research are summarized. The symposium contributors describe recent advances in expectancy theory and discuss their implications for assessment and for understanding the processes of development and change in the behavioral domain of alcohol use. First, findings are integrated across the diverse domains in which the expectancy concept has been applied. Second, the implications of expectancy theory for the measurement of expectancy structure and process are examined. Third, research and theory regarding alcohol expectancy development and change are presented, with an emphasis on the role of expectancies as mediators of known antecedents of drinking. Finally, an experimental procedure for investigating the causal role of expectancies is described, together with its implications for theory testing and prevention or intervention programming. Collectively, the symposium contributions demonstrate the utility of an integrated expectancy theory for the generation of innovative research operations and new insights regarding behavior development and change. Consistent with the notion of consilience, expectancy theory has demonstrated a convergence of findings across different levels of analysis, as well as across different operations, methods, and research designs.

Actor-Network Theory and its role in understanding the implementation of information technology developments in healthcare.

PubMed

Cresswell, Kathrin M; Worth, Allison; Sheikh, Aziz

2010-11-01

Actor-Network Theory (ANT) is an increasingly influential, but still deeply contested, approach to understand humans and their interactions with inanimate objects. We argue that health services research, and in particular evaluations of complex IT systems in health service organisations, may benefit from being informed by Actor-Network Theory perspectives. Despite some limitations, an Actor-Network Theory-based approach is conceptually useful in helping to appreciate the complexity of reality (including the complexity of organisations) and the active role of technology in this context. This can prove helpful in understanding how social effects are generated as a result of associations between different actors in a network. Of central importance in this respect is that Actor-Network Theory provides a lens through which to view the role of technology in shaping social processes. Attention to this shaping role can contribute to a more holistic appreciation of the complexity of technology introduction in healthcare settings. It can also prove practically useful in providing a theoretically informed approach to sampling (by drawing on informants that are related to the technology in question) and analysis (by providing a conceptual tool and vocabulary that can form the basis for interpretations). We draw on existing empirical work in this area and our ongoing work investigating the integration of electronic health record systems introduced as part of England's National Programme for Information Technology to illustrate salient points. Actor-Network Theory needs to be used pragmatically with an appreciation of its shortcomings. Our experiences suggest it can be helpful in investigating technology implementations in healthcare settings.

Black-White variations in the lagged reciprocal relationship between religiosity and perceived control.

PubMed

Oates, Gary

2013-06-01

This national longitudinal data-based multi-population LISREL study, the most comprehensive assessment to date of racial variations in the (in)congruity between religiosity and perceived control, gauges variation among Black and White Americans in the lagged reciprocal relationship between religiosity dimensions and mastery. Racial variation in the reciprocal religiosity-perceived control relationship has hitherto gone un-addressed. Prior investigations have also typically utilised cross-sectional samples - often from regional or age-specific populations. The observed public religiosity-mastery relationship over time exhibits signs of mutual reinforcement among Blacks: public religiosity enhances Blacks' subsequent mastery, while prior mastery borderline-significantly enhances their public religiosity. The subjective religiosity-mastery relationship among Whites evinces a marginally countervailing pattern: Subjective religiosity diminishes Whites' mastery, while mastery borderline-significantly enhances their subjective religiosity. The inordinately positive public religiosity-effect on Blacks' mastery notably constitutes solid support for the " resource compensation " perspective on the impact of religiosity on mastery across dominant and subordinate groups.

The ego-moving metaphor of time relies on visual experience: No representation of time along the sagittal space in the blind.

PubMed

Rinaldi, Luca; Vecchi, Tomaso; Fantino, Micaela; Merabet, Lotfi B; Cattaneo, Zaira

2018-03-01

In many cultures, humans conceptualize the past as behind the body and the future as in front. Whether this spatial mapping of time depends on visual experience is still not known. Here, we addressed this issue by testing early-blind participants in a space-time motor congruity task requiring them to classify a series of words as referring to the past or the future by moving their hand backward or forward. Sighted participants showed a preferential mapping between forward movements and future-words and backward movements and past-words. Critically, blind participants did not show any such preferential time-space mapping. Furthermore, in a questionnaire requiring participants to think about past and future events, blind participants did not appear to perceive the future as psychologically closer than the past, as it is the case of sighted individuals. These findings suggest that normal visual development is crucial for representing time along the sagittal space. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Models of physician-patient relationships in pharmaceutical direct-to-consumer advertising and consumer interviews.

PubMed

Arney, Jennifer; Lewin, Benjamin

2013-07-01

The rise of direct-to-consumer advertising (DTCA) has mirrored, if not facilitated, the shift toward more active health care consumers. We used content analysis to identify models of physician-patient interaction in DTCA from the 1997 to 2006 issues of a broad sample of women's, men's, and common readership magazines. We also conducted 36 in-depth interviews to examine the ways consumers receive and regard advertising messages, and to explore their preferences for clinical communication and decision making. We identified four models of physician-patient relationships that vary in their locus of control (physician, patient, or shared) and the form of support sought or obtained in the relationship (emotional or instrumental). Whereas consumer interviews reflected references to all four models of interaction, only two appeared in DTCA. The limited range of interactions seen in these advertisements creates a lack of congruity between interaction styles found in advertisements vs. styles reported by actual consumers.

In search of a principled theory of the 'value' of knowledge.

PubMed

Castelfranchi, Cristiano

2016-01-01

A theory of the Value/Utility of information and knowledge (K) is not really there. This would require a theory of the centrality of Goals in minds, and of the role of K relative to Goals and their dynamics. K value is a notion relative to Goal value. Inf/K is precisely a resource, a means and the value of means depends on the value of their possible functions and uses. The claim of this paper is that Ks have a Value and Utility, they can be more or less 'precious'; they have a cost and imply some risks; they can be not only useful but negative and dangerous. We also examine the 'quality' of this resource: its reliability; and its crucial role in goal processing: activating goals, abandoning, choosing, planning, formulating intentions, decide to act. 'Relevance theory', Information theory, Epistemic Utility theory, etc. are not enough for providing a theory of the Value/Utility of K. And also truthfulness is not 'the' Value of K. Even true information can be noxious for the subject.

Comparison of the Modified Biot-Gassmann Theory and the Kuster-Toksoz Theory in Predicting Elastic Velocities of Sediments

USGS Publications Warehouse

Lee, Myung W.

2008-01-01

Elastic velocities of water-saturated sandstones depend primarily on porosity, effective pressure, and the degree of consolidation. If the dry-frame moduli are known, from either measurements or theoretical calculations, the effect of pore water on velocities can be modeled using the Gassmann theory. Kuster and Toksoz developed a theory based on wave-scattering theory for a variety of inclusion shapes, which provides a means for calculating dry- or wet-frame moduli. In the Kuster-Toksoz theory, elastic wave velocities through different sediments can be predicted by using different aspect ratios of the sediment's pore space. Elastic velocities increase as the pore aspect ratio increases (larger pore aspect ratio describes a more spherical pore). On the basis of the velocity ratio, which is assumed to be a function of (1-0)n, and the Biot-Gassmann theory, Lee developed a semi-empirical equation for predicting elastic velocities, which is referred to as the modified Biot-Gassmann theory of Lee. In this formulation, the exponent n, which depends on the effective pressure and the degree of consolidation, controls elastic velocities; as n increases, elastic velocities decrease. Computationally, the role of exponent n in the modified Biot-Gassmann theory by Lee is similar to the role of pore aspect ratios in the Kuster-Toksoz theory. For consolidated sediments, either theory predicts accurate velocities. However, for unconsolidated sediments, the modified Biot-Gassmann theory by Lee performs better than the Kuster-Toksoz theory, particularly in predicting S-wave velocities.

The use and limitations of attachment theory in child psychotherapy.

PubMed

Zilberstein, Karen

2014-03-01

Attachment theory and research has proliferated in recent years, spawning new ideas and applications to child therapy. Some of those interventions are creative and useful and rest on solid theory and research, whereas others derive from tenuous assumptions. As an important developmental construct, attachment plays a role in every therapy, but defining that role can be difficult. Therapists must recognize the significance of attachment in treatment but not at the expense of recognizing and treating other issues. This article provides an overview of attachment theory and attachment-based interventions and discusses how to apply those constructs to therapeutic work with children. It reviews attachment theory, assessment, and treatments, and discusses how attachment-focused interventions can be combined with other therapeutic needs and methods. It also considers limitations in the current clinical application of attachment and makes recommendations for further research. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Being and doing politics: an outdated model or 21st century reality?

PubMed

Carnegie, Elaine; Kiger, Alice

2009-09-01

This paper presents a discussion of how critical social theory can be used as a tool for research, reflection and exploration of the political role of the nurse. Sociological theory can be used to examine ideologies within nursing systems in order to contribute to the future development of the profession. The importance of critical social theory has been identified in the literature as being directly relevant to holism which is central to the nature of nursing. Texts published in English were identified from 1990 to 2008 using the keywords critical social theory, community nursing, political advocacy, social justice, sociological theory, health inequalities, health democracy, equity and inequality. Critical social theory can be used as a tool to highlight ethical ways to practise nursing. One reason for examination of the community nurse's political role is a shift in focus from the individual as patient to communities experiencing health inequalities. Nursing needs to decide whether the profession will work at the political level, and where advocacy and citizenship are located within a community role. Nurse educators must prepare nurses for political participation, and nurse managers need to focus on national and local contexts in order to encourage policy analysis and community engagement within nursing practice. An understanding of critical social theory can aid decision-making in relation to global and local policy, enable the nursing profession to respond to social injustice, and permit nurses to work with communities in the pursuit of community health.

Predicting attendance at peer-assisted study sessions for statistics: role identity and the theory of planned behavior.

PubMed

White, Katherine M; Thomas, Ian; Johnston, Kim L; Hyde, Melissa K

2008-08-01

Using a prospective study of 77 1st-year psychology students' voluntary attendance at peer-assisted study sessions for statistics, the authors tested the addition of role identity to the theory of planned behavior. The authors used a revised set of role-identity items to capture the personal and social aspects of role identity within a specific behavioral context. At the commencement of the semester, the authors assessed the students' attitudes, subjective norm, perceived behavioral control, role identity, and intention. The authors examined the students' class attendance records 3 months later. Attitudes and perceived behavioral control predicted intention, with intention as the sole predictor of attendance. Role identity also predicted intention, reflecting the importance of the student role identity in influencing decision making related to supplementary academic activities.

Gender differences in ethical perceptions of business practices: a social role theory perspective.

PubMed

Franke, G R; Crown, D F; Spake, D F

1997-12-01

This study presents a meta-analysis of research on gender differences in perceptions of ethical decision making. Data from more than 20,000 respondents in 66 samples show that women are more likely than men to perceive specific hypothetical business practices as unethical. As suggested by social role theory (A. H. Eagly, 1987), the gender difference observed in precareer (student) samples declines as the work experience of samples increases. Social role theory also accounts for greater gender differences in nonmonetary issues than in monetary issues. T. M. Jones's (1991) issue-contingent model of moral intensity helps explain why gender differences vary across types of behavior. Contrary to expectations, differences are not influenced by the sex of the actor or the target of the behavior and do not depend on whether the behavior involves personal relationships or action vs. inaction.

The role of interoceptive inference in theory of mind.

PubMed

Ondobaka, Sasha; Kilner, James; Friston, Karl

2017-03-01

Inferring the intentions and beliefs of another is an ability that is fundamental for social and affiliative interactions. A substantial amount of empirical evidence suggests that making sense of another's intentional and belief states (i.e. theory of mind) relies on exteroceptive (e.g. visual and auditory) and proprioceptive (i.e. motor) signals. Yet, despite its pivotal role in the guidance of behaviour, the role of the observer's interoceptive (visceral) processing in understanding another's internal states remains unexplored. Predicting and keeping track of interoceptive bodily states - which inform intentions and beliefs that guide behaviour - is one of the fundamental purposes of the human brain. In this paper, we will focus on the role of interoceptive predictions, prescribed by the free energy principle, in making sense of internal states that cause another's behaviour. We will discuss how multimodal expectations induced at deep (high) hierarchical levels - that necessarily entail interoceptive predictions - contribute to inference about others that is at the heart of theory of mind.

Similarity spectra analysis of high-performance jet aircraft noise.

PubMed

Neilsen, Tracianne B; Gee, Kent L; Wall, Alan T; James, Michael M

2013-04-01

Noise measured in the vicinity of an F-22A Raptor has been compared to similarity spectra found previously to represent mixing noise from large-scale and fine-scale turbulent structures in laboratory-scale jet plumes. Comparisons have been made for three engine conditions using ground-based sideline microphones, which covered a large angular aperture. Even though the nozzle geometry is complex and the jet is nonideally expanded, the similarity spectra do agree with large portions of the measured spectra. Toward the sideline, the fine-scale similarity spectrum is used, while the large-scale similarity spectrum provides a good fit to the area of maximum radiation. Combinations of the two similarity spectra are shown to match the data in between those regions. Surprisingly, a combination of the two is also shown to match the data at the farthest aft angle. However, at high frequencies the degree of congruity between the similarity and the measured spectra changes with engine condition and angle. At the higher engine conditions, there is a systematically shallower measured high-frequency slope, with the largest discrepancy occurring in the regions of maximum radiation.

There are three ways we can utilize theory in practice: (1) to reexamine our traditional approaches; (2) to give some direction to our future practices; and (3) to generate…

Observables, measurements and phase operators from a Bohmian perspective

NASA Technical Reports Server (NTRS)

Daumer, Martin; Goldstein, Sheldon

1993-01-01

Bohmian mechanics is a deterministic theory of point particles in motion. While avoiding all the paradoxes of nonrelativistic quantum mechanics, it yields the quantum formalism itself--especially the role of self-adjoint operators--as a macroscopic measurement formalism. As an 'application' it is shown that much of the confusion connected with the phase operator for the electromagnetic field arises from a misunderstanding of the role of operators in quantum theory.

Beyond Dominance and Competence: A Moral Virtue Theory of Status Attainment.

PubMed

Bai, Feng

2017-08-01

Recognition has grown that moral behavior (e.g., generosity) plays a role in status attainment, yet it remains unclear how, why, and when demonstrating moral characteristics enhances status. Drawing on philosophy, anthropology, psychology, and organizational behavior, I critically review a third route to attaining status: virtue, and propose a moral virtue theory of status attainment to provide a generalized account of the role of morality in status attainment. The moral virtue theory posits that acts of virtue elicit feelings of warmth and admiration (for virtue), and willing deference, toward the virtuous actor. I further consider how the scope and priority of moralities and virtues endorsed by a moral community are bound by culture and social class to affect which moral characteristics enhance status. I end by outlining an agenda for future research into the role of virtue in status attainment.

From 1888 to his death in 1921, Russian Prince Peter Kropotkin forced biologists to ask themselves whether natural selection inevitably led to a dog-eat-dog world, or whether pro-social behavior could also be a product of the evolutionary process. In this historical vignette, I focus on Kropotkin's theory of "mutual aid," with emphasis on the role that empathy played in that theory, and the unexpected source--economist Adam Smith's 1759 book, The Theory of Moral Sentiments--of Kropotkin's ideas on empathy in animals. © 2013 Wiley Periodicals, Inc.

Role tuning between caregiver and care receiver during discharge transition: an illustration of role function mode in Roy's adaptation theory.

Shyu, Y I

2000-10-01

The purpose of this study was to develop a conceptual framework to explain the interaction between the caregiver and the care receiver during the discharge transition. Data from face-to-face interviews with 12 care receivers and 16 caregivers were subjected to constant comparative analysis. Findings revealed that role tuning was the process used by caregivers and care receivers to achieve a harmonious pattern of caregiving and care receiving during the transition from hospital to home. This empirical finding can illustrate the concept of role function mode in the Roy adaptation theory and sensitize healthcare providers to the needs of the families during the discharge transition.

Holistic Darwinism: the new evolutionary paradigm and some implications for political science.

PubMed

Corning, Peter A

2008-03-01

Holistic Darwinism is a candidate name for a major paradigm shift that is currently underway in evolutionary biology and related disciplines. Important developments include (1) a growing appreciation for the fact that evolution is a multilevel process, from genes to ecosystems, and that interdependent coevolution is a ubiquitous phenomenon in nature; (2) a revitalization of group selection theory, which was banned (prematurely) from evolutionary biology over 30 years ago (groups may in fact be important evolutionary units); (3) a growing respect for the fact that the genome is not a "bean bag" (in biologist Ernst Mayr's caricature), much less a gladiatorial arena for competing selfish genes, but a complex, interdependent, cooperating system; (4) an increased recognition that symbiosis is an important phenomenon in nature and that symbiogenesis is a major source of innovation in evolution; (5) an array of new, more advanced game theory models, which support the growing evidence that cooperation is commonplace in nature and not a rare exception; (6) new research and theoretical work that stresses the role of nurture in evolution, including developmental processes, phenotypic plasticity, social information transfer (culture), and especially the role of behavioral innovations as pacemakers of evolutionary change (e.g., niche construction theory, which is concerned with the active role of organisms in shaping the evolutionary process, and gene-culture coevolution theory, which relates especially to the dynamics of human evolution); (7) and, not least, a broad effort to account for the evolution of biological complexity--from major transition theory to the "Synergism Hypothesis." Here I will briefly review these developments and will present a case for the proposition that this paradigm shift has profound implications for the social sciences, including specifically political theory, economic theory, and political science as a discipline. Interdependent superorganisms, it turns out, have played a major role in evolution--from eukaryotes to complex human societies.

The role of oxytocin in mothers' theory of mind and interactive behavior during the perinatal period.

PubMed

MacKinnon, Anna L; Gold, Ian; Feeley, Nancy; Hayton, Barbara; Carter, C Sue; Zelkowitz, Phyllis

2014-10-01

The present longitudinal study examined the relations between plasma oxytocin, theory of mind, and maternal interactive behavior during the perinatal period. A community sample of women was assessed at 12-14 weeks gestation, 32-34 weeks gestation, and 7-9 weeks postpartum. Oxytocin during late pregnancy was significantly positively correlated with a measure of theory of mind, and predicted theory of mind ability after controlling for parity, maternal education, prenatal psychosocial risk, and general anxiety, measured during the first trimester. Theory of mind was associated with less remote and less depressive maternal interactive behavior. Oxytocin, across all time points, was not directly related to maternal interactive behavior. However, there was a significant indirect effect of oxytocin during late pregnancy on depressive maternal behavior via theory of mind ability. These preliminary findings suggest that changes in the oxytocinergic system during the perinatal period may contribute to the awareness of social cues, which in turn plays a role in maternal interactive behavior.

Conceptual change and preschoolers' theory of mind: evidence from load-force adaptation.

PubMed

Sabbagh, Mark A; Hopkins, Sydney F R; Benson, Jeannette E; Flanagan, J Randall

2010-01-01

Prominent theories of preschoolers' theory of mind development have included a central role for changing or adapting existing conceptual structures in response to experiences. Because of the relatively protracted timetable of theory of mind development, it has been difficult to test this assumption about the role of adaptation directly. To gain evidence that cognitive adaptation is particularly important for theory of mind development, we sought to determine whether individual differences in cognitive adaptation in a non-social domain predicted preschoolers' theory of mind development. Twenty-five preschoolers were tested on batteries of theory of mind tasks, executive functioning tasks, and on their ability to adapt their lifting behavior to smoothly lift an unexpectedly heavy object. Results showed that children who adapted their lifting behavior more rapidly performed better on theory of mind tasks than those who adapted more slowly. These findings held up when age and performance on the executive functioning battery were statistically controlled. Although preliminary, we argue that this relation is attributable to individual differences in children's domain general abilities to efficiently change existing conceptual structures in response to experience.

A Neurophysiological Study of Semantic Processing in Parkinson's Disease.

Angwin, Anthony J; Dissanayaka, Nadeeka N W; Moorcroft, Alison; McMahon, Katie L; Silburn, Peter A; Copland, David A

2017-01-01

Cognitive-linguistic impairments in Parkinson's disease (PD) have been well documented; however, few studies have explored the neurophysiological underpinnings of semantic deficits in PD. This study investigated semantic function in PD using event-related potentials. Eighteen people with PD and 18 healthy controls performed a semantic judgement task on written word pairs that were either congruent or incongruent. The mean amplitude of the N400 for new incongruent word pairs was similar for both groups, however the onset latency was delayed in the PD group. Further analysis of the data revealed that both groups demonstrated attenuation of the N400 for repeated incongruent trials, as well as attenuation of the P600 component for repeated congruent trials. The presence of N400 congruity and N400 repetition effects in the PD group suggests that semantic processing is generally intact, but with a slower time course as evidenced by the delayed N400. Additional research will be required to determine whether N400 and P600 repetition effects are sensitive to further cognitive decline in PD. (JINS, 2017, 23, 78-89).

Changes across age groups in self-choice elaboration and incidental memory.

Toyota, Hiroshi; Tatsumi, Tomoko

2003-04-01

This study investigated differences in the self-choice elaboration and an experimenter-provided elaboration on incidental memory of 7- to 12-yr.-olds. In a self-choice elaboration condition 34 second and 25 sixth graders were asked to choose one of the two sentence frames into which each target could fit more congruously, whereas in an experimenter-provided elaboration they were asked to judge the congruity of each target to each frame. In free recall, sixth graders recalled targets in bizarre sentence frames better than second graders for self-choice elaboration condition. An age difference was not found for the experimenter-provided elaboration. In cued recall self-choice elaboration led to better performance of sixth graders for recalling targets than an experimenter-provided elaboration in both bizarre and common sentence frames. However, the different types of elaboration did not alter the recall of second graders. These results were interpreted as showing that the effectiveness of a self-choice elaboration depends on the subjects' age and the type of sentence.

Gender role orientation and anxiety symptoms among African american adolescents.

PubMed

Palapattu, Anuradha G; Kingery, Julie Newman; Ginsburg, Golda S

2006-06-01

The present study evaluated gender role theory as an explanation for the observed gender differences in anxiety symptoms among adolescents. Specifically, the relation between gender, gender role orientation (i.e., masculinity and femininity), self-esteem, and anxiety symptoms was examined in a community sample of 114 African Americans aged 14 to 19 (mean age 15.77; 57 girls). Results revealed that masculinity was negatively associated with anxiety symptoms whereas femininity was positively associated with anxiety symptoms. Gender role orientation accounted for unique variance in anxiety scores above biological gender and self-esteem, and self-esteem moderated the relation between femininity (but not masculinity) and overall anxiety symptoms. Consistent with research on children and Caucasians, findings supported gender role theory as a partial explanation for the observed gender disparity in anxiety symptoms among African American adolescents.

Maternal role satisfaction: a new approach to assessing parenting.

PubMed

Ohashi, J P

1992-01-01

There is a need to study the maternal role beyond the child's first year of life. This investigation, using a framework of Locke's expectancy theory, describes the expectations, surprises, values, and satisfactions experienced by 102 mothers of teens. Content analysis of written narratives describing surprises encountered by these mothers is also presented. Data were collected by questionnaire. Findings offer support for Locke's theory in two ways: (1) expectation for role was less important than value attainment in predicting the level of maternal role satisfaction, and (2) encountering at least one positive surprise was associated with a higher level of maternal role satisfaction. These variables are offered as a useful nursing approach to the assessment of the parenting experience. Knowledge of the satisfactions reported may be encouraging to mothers anticipating this stage of life.

The middle way of evolution

PubMed Central

Hunt, Tam

2012-01-01

This essay provides a critical review of two recent books on evolution: Richard Dawkins’ The Greatest Show on Earth, and Jerry Coyne’s Why Evolution is True, as well as a critique of mainstream evolutionary theory and of natural selection. I also suggest a generalization of sexual selection theory that acknowledges mind as pervasive in nature. Natural selection, as the primary theory of how biological change occurs, must be carefully framed to avoid the long-standing “tautology problem” and must also be modified to more explicitly include the role of mind in evolution. A propensity approach to natural selection, in which “expected fitness” is utilized rather than “fitness,” can save natural selection from tautology. But to be a productive theory, natural selection theory should be placed alongside sexual selection – which is explicitly agentic/intentional – as a twin force, but also placed alongside purely endogenous factors such as genetic drift. This framing is contrary to the normal convention that often groups all of these factors under the rubric of “natural selection.” I suggest some approaches for improving modern evolutionary theory, including a “generalized sexual selection,” a panpsychist extension of Darwin’s theory of sexual selection that explicitly recognizes the role of mind at all levels of nature and which may play the part of a general theory of evolution better than natural selection theory.

An evolving joint space campaign concept and the Army's role

NASA Astrophysics Data System (ADS)

Franke, Henry G., III

1992-05-01

This monograph examines the question of an evolving joint space campaign concept and the Army's role in it over the next 20 years. Analysis progresses logically through a series of topics in order to arrive at a complete picture of this evolutionary space campaign concept, as well as the Army's place in it. Space plays an increasingly important role in US military operations, particularly when tied together with advances in information management. The synergistic impact due to the combination of these two areas suggests a revolution in the nature of modern warfare which saw its emergence during the 1991 Gulf War. With this theme in mind, I review the Army's roles, missions, and historical involvement in space, then present technological opportunities and a perspective on investment strategies for military space. A detailed discussion of a near-term military space theory and current space doctrines supports the need for an accepted military space theory as a foundation for Joint and Service space doctrines, space campaign design and conduct, and space force generation. The basis for such a theory is established using Julian Corbett's maritime warfare theory as a point of departure, while recognizing that space as a unique military operating medium requires its own theory and a regime to govern the application of space forces.

Examining alcohol consumption with the theory of planned behaviour: Do health and alcohol knowledge play a role?

PubMed

Hasking, Penelope; Schofield, Lachlan

2015-01-01

We used the theory of planned behaviour (TPB) to investigate factors associated with alcohol consumption among university students, and to examine whether general or alcohol-specific health knowledge acts as a moderator in the relationship between elements of the theory and drinking behaviour. Participants were 258 Australian undergraduate university students (79% female) who completed an online questionnaire, assessing the constructs of interest. The hypothesis that intentions and behaviour would be successfully predicted using the theory was generally supported. Little evidence for the moderating effect of knowledge on the TPB variables was observed, although both general and alcohol-specific health knowledge moderated the relationship between intentions and behaviours. Contrary to expectation, more accurate knowledge strengthened this relationship. Further work is necessary to investigate the role of knowledge in limiting alcohol-related harms.

Emotional collectives: How groups shape emotions and emotions shape groups.

PubMed

van Kleef, Gerben A; Fischer, Agneta H

2016-01-01

Group settings are epicentres of emotional activity. Yet, the role of emotions in groups is poorly understood. How do group-level phenomena shape group members' emotional experience and expression? How are emotional expressions recognised, interpreted and shared in group settings? And how do such expressions influence the emotions, cognitions and behaviours of fellow group members and outside observers? To answer these and other questions, we draw on relevant theoretical perspectives (e.g., intergroup emotions theory, social appraisal theory and emotions as social information theory) and recent empirical findings regarding the role of emotions in groups. We organise our review according to two overarching themes: how groups shape emotions and how emotions shape groups. We show how novel empirical approaches break important new ground in uncovering the role of emotions in groups. Research on emotional collectives is thriving and constitutes a key to understanding the social nature of emotions.

Traditional fire-use, landscape transition, and the legacies of social theory past.

PubMed

Coughlan, Michael R

2015-12-01

Fire-use and the scale and character of its effects on landscapes remain hotly debated in the paleo- and historical-fire literature. Since the second half of the nineteenth century, anthropology and geography have played important roles in providing theoretical propositions and testable hypotheses for advancing understandings of the ecological role of human-fire-use in landscape histories. This article reviews some of the most salient and persistent theoretical propositions and hypotheses concerning the role of humans in historical fire ecology. The review discusses this history in light of current research agendas, such as those offered by pyrogeography. The review suggests that a more theoretically cognizant historical fire ecology should strive to operationalize transdisciplinary theory capable of addressing the role of human variability in the evolutionary history of landscapes. To facilitate this process, researchers should focus attention on integrating more current human ecology theory into transdisciplinary research agendas.

Development of an Integrated Theory of Surgical Recovery in Older Adults.

PubMed

Ann DiMaria-Ghalili, Rose

2016-01-01

Experts argue the health care system is not prepared to meet the unique needs of older surgical patients, including how to provide the best care during the recovery phase. Nutrition plays a critical role in the recovery of surgical patients. Since older adults are at risk for malnutrition, examining the role of nutrition as a mediator for surgical recovery across the care continuum in older adults is critical. Presently there is a paucity of frameworks, models, and guidelines that integrate the role of nutrition on the trajectory of postoperative recovery in older surgical patients. The purpose of this article is to introduce the Integrated Theory of Surgical Recovery in Older Adults, an interdisciplinary middle-range theory, so that scholars, researchers, and clinicians can use this framework to promote recovery from surgery in older adults by considering the contribution of mediators of recovery (nutritional status, functional status, and frailty) unique to the older adults.

The Need for a Kinetics for Biological Transport

PubMed Central

1973-01-01

The traditional theory of transport across capillary membranes via a laminar Poiseuille flow is shown to be invalid. It is demonstrated that the random, diffusive nature of the molecular flow and interactions with the “pore” walls play an important role in the transport process. Neither the continuum Navier-Stokes theory nor the equivalent theory of irreversible thermodynamics is adequate to treat the problem. Combination of near-continuum hydrodynamic theory, noncontinuum kinetic theory, and the theory of fluctuations provides a first step toward modeling both liquid processes in general and membrane transport processes as a specific application.

The essential role of social theory in qualitative public health research.

Willis, Karen; Daly, Jeanne; Kealy, Michelle; Small, Rhonda; Koutroulis, Glenda; Green, Julie; Gibbs, Lisa; Thomas, Samantha

2007-10-01

To define the role of social theory and examine how research studies using qualitative methods can use social theory to generalize their results beyond the setting of the study or to other social groups. The assumptions underlying public health research using qualitative methods derive from a range of social theories that include conflict theory, structural functionalism, symbolic interactionism, the sociology of knowledge and feminism. Depending on the research problem, these and other social theories provide conceptual tools and models for constructing a suitable research framework, and for collecting and analysing data. In combination with the substantive health literature, the theoretical literature provides the conceptual bridge that links the conclusions of the study to other social groups and settings. While descriptive studies using qualitative research methods can generate important insights into social experience, the use of social theory in the construction and conduct of research enables researchers to extrapolate their findings to settings and groups broader than the ones in which the research was conducted.

1989-01-01

We present correlations of extent of temporal lobectomy for intractable epilepsy with postoperative memory changes (20 cases) and abnormalities of visual field and neurologic examination (45 cases). Postoperative magnetic resonance imaging (MRI) in the coronal plane was used to quantify anteroposterior extent of resection of various quadrants of the temporal lobe, using a 20-compartment model of that structure. The Wechsler Memory Scale-Revised (WMS-R) was administered preoperatively and postoperatively. Postoperative decrease in percentage of retention of verbal material correlated with extent of medial resection of left temporal lobe, whereas decrease in percentage of retention of visual material correlated with extent of medial resection of right temporal lobe. These correlations approached but did not reach statistical significance. Extent of resection correlated significantly with the presence of visual field defect on perimetry testing but not with severity, denseness, or congruity of the defect. There was no correlation between postoperative dysphasia and extent of resection in any quadrant. Assessment of extent of resection after temporal lobectomy allows a rational interpretation of postoperative neurologic deficits in light of functional anatomy of the temporal lobe.

The Functional Role of the Periphery in Emotional Language Comprehension

PubMed Central

Havas, David A.; Matheson, James

2013-01-01

Language can impact emotion, even when it makes no reference to emotion states. For example, reading sentences with positive meanings (“The water park is refreshing on the hot summer day”) induces patterns of facial feedback congruent with the sentence emotionality (smiling), whereas sentences with negative meanings induce a frown. Moreover, blocking facial afference with botox selectively slows comprehension of emotional sentences. Therefore, theories of cognition should account for emotion-language interactions above the level of explicit emotion words, and the role of peripheral feedback in comprehension. For this special issue exploring frontiers in the role of the body and environment in cognition, we propose a theory in which facial feedback provides a context-sensitive constraint on the simulation of actions described in language. Paralleling the role of emotions in real-world behavior, our account proposes that (1) facial expressions accompany sudden shifts in wellbeing as described in language; (2) facial expressions modulate emotional action systems during reading; and (3) emotional action systems prepare the reader for an effective simulation of the ensuing language content. To inform the theory and guide future research, we outline a framework based on internal models for motor control. To support the theory, we assemble evidence from diverse areas of research. Taking a functional view of emotion, we tie the theory to behavioral and neural evidence for a role of facial feedback in cognition. Our theoretical framework provides a detailed account that can guide future research on the role of emotional feedback in language processing, and on interactions of language and emotion. It also highlights the bodily periphery as relevant to theories of embodied cognition. PMID:23750145

Examining the role of emotion in suicidality: negative urgency as an amplifier of the relationship between components of the interpersonal-psychological theory of suicidal behavior and lifetime number of suicide attempts.

PubMed

Anestis, Michael D; Joiner, Thomas E

2011-03-01

Joiner's (2005) interpersonal-psychological theory of suicidal behavior posits that an individual must exhibit elevations on three variables--perceived burdensomeness, thwarted belongingness, and the acquired capability for suicide--in order to enact lethal self-harm. Thus far, however, no research has examined the role of emotion in this process or whether the interaction of these three variables is more problematic for certain populations than for others. We sought to address these voids by examining the role of negative urgency as an amplifier of the relationship between the components of the theory and lifetime number of suicide attempts. Results indicated that the four-way interaction of negative urgency and the three components of the theory predicted lifetime number of suicide attempts, controlling for depression symptoms and sex. Additionally, the three-way interaction of the theory components significantly predicted lifetime number of suicide attempts in the full sample. Furthermore, for individuals with negative urgency scores at or above the median, the three-way interaction of the theory components significantly predicted lifetime number of suicide attempts whereas, for individuals with negative urgency scores below the median, the interaction was non-significant. These findings indicate that, although elevations on the three components of the theory may be dangerous for anyone, this is particularly true for individuals exhibiting high levels of negative urgency, as they might be more likely to quickly develop suicidal ideation and resort to painful self-harming behaviors while experiencing negative affective states.

A Unifying Theory of Biological Function.

PubMed

van Hateren, J H

2017-01-01

A new theory that naturalizes biological function is explained and compared with earlier etiological and causal role theories. Etiological (or selected effects) theories explain functions from how they are caused over their evolutionary history. Causal role theories analyze how functional mechanisms serve the current capacities of their containing system. The new proposal unifies the key notions of both kinds of theories, but goes beyond them by explaining how functions in an organism can exist as factors with autonomous causal efficacy. The goal-directedness and normativity of functions exist in this strict sense as well. The theory depends on an internal physiological or neural process that mimics an organism's fitness, and modulates the organism's variability accordingly. The structure of the internal process can be subdivided into subprocesses that monitor specific functions in an organism. The theory matches well with each intuition on a previously published list of intuited ideas about biological functions, including intuitions that have posed difficulties for other theories.

Attachment in integrative neuroscientific perspective.

PubMed

Hruby, Radovan; Hasto, Jozef; Minarik, Peter

2011-01-01

Attachment theory is a very influential general concept of human social and emotional development, which emphasizes the role of early mother-infant interactions for infant's adaptive behavioural and stress copying strategies, personality organization and mental health. Individuals with disrupted development of secure attachment to mother/primary caregiver are at higher risk of developing mental disorders. This theory consists of the complex developmental psycho-neurobiological model of attachment and emerges from principles of psychoanalysis, evolutionary biology, cognitive-developmental psychology, ethology, physiology and control systems theory. The progress of modern neuroscience enables interpretation of neurobiological aspects of the theory as multi-level neural interactions and functional development of important neural structures, effects of neuromediattors, hormones and essential neurobiological processes including emotional, cognitive, social interactions and the special key role of mentalizing. It has multiple neurobiological, neuroendocrine, neurophysiological, ethological, genetic, developmental, psychological, psychotherapeutic and neuropsychiatric consequences and is a prototype of complex neuroscientific concept as interpretation of modern integrated neuroscience.

Lasiuk, Gerri C; Ferguson, Linda M

2005-01-01

This article presents a brief overview of theory as background for a more detailed discussion of midrange theory-its origins, the critical role for midrange theory in the development of nursing practice knowledge, and the criteria for evaluating midrange theory. We then chronicle Cheryl Tatano Beck's program of research on postpartum depression (PPD) and advance the thesis that her theory of PPD, titled Teetering on the Edge, is an exemplar of a substantive midrange nursing theory. We demonstrate Beck's progression from identification of a clinical problem to exploratory-descriptive research, to concept analysis and midrange theory development, and finally to the application and testing of the theory in the clinical setting. Through ongoing refinement and testing of her theory, Beck has increased its generalizability across various practice settings and continually identifies new issues for investigation. Beck's program of research on PPD exemplifies using nursing outcomes to build and test nursing practice knowledge.

A theory of eu-estrogenemia: a unifying concept

PubMed Central

Turner, Ralph J.; Kerber, Irwin J.

2017-01-01

Abstract Objective: The aim of the study was to propose a unifying theory for the role of estrogen in postmenopausal women through examples in basic science, randomized controlled trials, observational studies, and clinical practice. Methods: Review and evaluation of the literature relating to estrogen. Discussion: The role of hormone therapy and ubiquitous estrogen receptors after reproductive senescence gains insight from basic science models. Observational studies and individualized patient care in clinical practice may show outcomes that are not reproduced in randomized clinical trials. The understanding gained from the timing hypothesis for atherosclerosis, the critical window theory in neurosciences, randomized controlled trials, and numerous genomic and nongenomic actions of estrogen discovered in basic science provides new explanations to clinical challenges that practitioners face. Consequences of a hypo-estrogenemic duration in women's lives are poorly understood. The Study of Women Across the Nation suggests its magnitude is greater than was previously acknowledged. We propose that the healthy user bias was the result of surgical treatment (hysterectomy with oophorectomy) for many gynecological maladies followed by pharmacological and physiological doses of estrogen to optimize patient quality of life. The past decade of research has begun to demonstrate the role of estrogen in homeostasis. Conclusions: The theory of eu-estrogenemia provides a robust framework to unify the timing hypothesis, critical window theory, randomized controlled trials, the basic science of estrogen receptors, and clinical observations of patients over the past five decades.

Why Don't I Help You? The Relationship between Role Stressors and Helping Behavior from a Cognitive Dissonance Perspective.

PubMed

Zhang, Li; Xia, Ying; Liu, Baowei; Han, Lu

2017-01-01

This paper proposes that role stressors decrease helping behavior by undermining employees' normative commitment from a cognitive dissonance perspective and social exchange theory. We also propose two competitive assumptions of the moderating effect of perceived organizational support (POS). In this paper, we first examine these hypotheses in Study 1 and then verify the cognitive dissonance perspective in Study 2. In Study 1, we collected data from 350 employees of two enterprises in China. The results indicated that role stressors had a negative link with helping behavior via the mediating role of normative commitment. The results also showed that POS strengthened the negative relationship between role stressors and normative commitment. In Study 2, we invited 104 employees to participate in a scenario experiment. The results found that role stressors had an impact on normative commitment via dissonance. Our studies verified the combination of cognitive dissonance perspective and social exchange theory to explain the impact of role stressors on helping behavior.

Evidence for the social role theory of stereotype content: observations of groups' roles shape stereotypes.

PubMed

Koenig, Anne M; Eagly, Alice H

2014-09-01

In applying social role theory to account for the content of a wide range of stereotypes, this research tests the proposition that observations of groups' roles determine stereotype content (Eagly & Wood, 2012). In a novel test of how stereotypes can develop from observations, preliminary research collected participants' beliefs about the occupational roles (e.g., lawyer, teacher, fast food worker, chief executive officer, store clerk, manager) in which members of social groups (e.g., Black women, Hispanics, White men, the rich, senior citizens, high school dropouts) are overrepresented relative to their numbers in the general population. These beliefs about groups' typical occupational roles proved to be generally accurate when evaluated in relation to data from the Bureau of Labor Statistics. Then, correlational studies predicted participants' stereotypes of social groups from the attributes ascribed to group members' typical occupational roles (Studies 1a, 1b, and 1c), the behaviors associated with those roles (Study 2), and the occupational interest profile of the roles (Study 3). As predicted by social role theory, beliefs about the attributes of groups' typical roles were strongly related to group stereotypes on both communion and agency/competence. In addition, an experimental study (Study 4) demonstrated that when social groups were described with changes to their typical social roles in the future, their projected stereotypes were more influenced by these future roles than by their current group stereotypes, thus supporting social role theory's predictions about stereotype change. Discussion considers the implications of these findings for stereotype change and the relation of social role theory to other theories of stereotype content. 2014 APA, all rights reserved

The role of pride in women with anorexia nervosa: A grounded theory study.

PubMed

Faija, Cintia L; Tierney, Stephanie; Gooding, Patricia A; Peters, Sarah; Fox, John R E

2017-12-01

Theory and clinical literature suggest that pride may play an important role in the maintenance of restrictive eating disorders. A grounded theory study explored experiences of, and reflections on, pride among women with a current or past diagnosis of anorexia nervosa. This is a qualitative study using grounded theory. Semistructured interviews were conducted with 21 women recruited from an eating disorder unit in England, and from a UK self-help organization. Grounded theory from a constructivist lens was used. Analysis involved coding, constant comparison, and memo-writing. Pride evolves over the course of anorexia nervosa. Two overarching conceptual categories were identified: 'pride becoming intertwined with anorexia' and 'pride during the journey towards recovery'. These categories encompassed different forms of pride: 'alluring pride', 'toxic pride', 'pathological pride', 'anorexia pride', 'shameful pride', 'recovery pride', and 'resilient pride'. Initially, pride contributed to self-enhancement and buffered negative emotions. As the condition progressed, pride became a challenge to health and interfered with motivation to change. During recovery, perceptions of pride altered as a healthy approach to living ensued. The evolving nature of pride plays a central role in development, maintenance, and treatment of anorexia nervosa. Understanding of pride and its role in psychotherapeutic work with this client group may increase motivation to change and promote recovery. Future work should investigate whether tackling pride in eating disorders increases treatment efficacy and reduces the risk of relapsing. Pride associated with anorexia appeared to evolve in nature. During early stages of the eating disorder, it stopped people from seeking help. Later on, it prevented them from seeing pride in healthy domains of life (outside anorexia). Over time, pride in anorexia became an overwhelming emotion that interfered with motivation to change. It is important for practitioners to assess and discuss pride in anorexia and its evolving nature during treatment. Understanding of pride and its role in psychotherapeutic work with this client group may increase motivation to change and promote recovery. © 2017 The British Psychological Society.

The Role of Pavlov's Theory in North Korea in the Late 1950s: Ideological Struggle in Medicine and Scientification of Traditional Medicine.

PubMed

Han, Sun-Hee; Kim, Ock-Joo

2013-12-01

This paper deals with Pavlov theory in North Korea in the late 1950s, focusing on its role in ideological struggle in medicine and in reinterpretation of traditional medicine. In North Korean Ministry of Health found Pavlov theory to have rich resources which could be used in the construction of the North Korea's socialist medicine. First of all, Pavlov theory provided the North Korean Communist Party with a powerful ideological weapon against capitalist medical thoughts, representing superior socialist medicine based upon Marx-Leninism and dialectical materialism. This paper examines the contents of Pavlov theory introduced in the North Korea from the Soviet Union in the late 1950s. Pavlov theory in the North Korea was not merely a political slogan but a unified medical system of thought, ranging from biological theory on the organism and pathogenesis to clinical theory. Nonetheless, Pavlov theory became Pavlov doctrine in the ideological struggle in healthcare field initiated by Kim Il Sung and the Communist Party. In the process of the ideological struggle, the abducted surgeon Kim Si-Chang was accused and purged of counter-revolutionary and refusal to conform to Pavlov doctrines by the Communist Party in 1959. Interestingly, Pavlov theory was used in reinterpretation of Traditional Medicine in North Korea from unscientific practice to a rich and scientific complementary medicine by connecting the two with common theoretical components such as Pavlov's typology. By the enthusiastic Communist Party members, Pavlov doctrine was introduced, transformed and exploited to build monolithic ideology system in medicine in North Korea in the late 1950s.

One of the key strategies in students' learning is being affected by models. Understanding the role-modeling process in education will help to make greater use of this training strategy. The aim of this grounded theory study was to explore Iranian nursing students and instructors' experiences about role modeling process. Data was analyzed by Glaserian's Grounded Theory methodology through semi-structured interviews with 7 faculty members, 2 nursing students; the three focus group discussions with 20 nursing students based on purposive and theoretical sampling was done for explaining role modeling process from four nursing faculties in Tehran. Through basic coding, an effort to comprehensive growth and excellence was made with the basic social process consisting the core category and through selective coding three phases were identified as: realizing and exposure to inadequate human and professional growth, facilitating human and professional growth and evolution. The role modeling process is taking place unconscious, involuntary, dynamic and with positive progressive process in order to facilitate overall growth in nursing student. Accordingly, the design and implementation of the designed model can be used to make this unconscious to conscious, active and voluntarily processes a process to help education administrators of nursing colleges and supra organization to prevent threats to human and professional in nursing students' education and promote nursing students' growth.

The effects of implicit gender role theories on gender system justification: Fixed beliefs strengthen masculinity to preserve the status quo.

PubMed

Kray, Laura J; Howland, Laura; Russell, Alexandra G; Jackman, Lauren M

2017-01-01

Four studies (n = 1199) tested support for the idea that implicit theories about the fixedness versus malleability of gender roles (entity vs. incremental theories) predict differences in the degree of gender system justification, that is, support for the status quo in relations between women and men in society. Relative to an incremental theory, the holding of an entity theory correlated with more system-justifying attitudes and self-perceptions (Study 1) for men and women alike. We also found that strength of identification with one's gender in-group was a stronger predictor of system justification for men than it was for women, suggesting men's defense of the status quo may be motivated by their membership in a high status group in the social hierarchy. In 3 experiments, we then tested whether exposure to a fixed gender role theory would lead men to identify more with masculine characteristics and their male gender group, thus increasing their defense of the gender system as fair and just. We did not expect a fixed gender role theory to trigger these identity-motivated responses in women. Overall, we found that, by increasing the degree of psychological investment in their masculine identity, adopting a fixed gender role theory increased men's rationalization of the gender status quo compared with when gender roles were perceived to be changeable. This suggests that, when men are motivated to align with their masculine identity, they are more likely to endorse the persistence of gender inequality as a way of affirming their status as "real men."

Hancock, Helen; Lloyd, Hilary; Campbell, Steve; Turnock, Chris; Craig, Stephen

2007-10-01

Plans for NHS reform include strategies to reduce the gap between theory and the realities of clinical practice, with the aim of improving patient care. The role of Lecturer Practitioners (LPs) as educators for nurses who 'bridge' the theory-practice gap forms a central part of this strategy. Given the amount of investment in the role and its potential, this study sought to evaluate the impact of the LP role within the education and practice setting from the perspective of key stakeholders. The study, which included five LPs from a range of backgrounds, followed the principles of stakeholder evaluation. Each LP and their line manager identified six informants who were familiar with the LP's role. The total sample consisted of 36 participants. Semi-structured interviews were used to gain the perceptions of stakeholders about the LP role. The emerging themes were then discussed, consensus reached, and a collaborative project report produced. The findings were derived from the perceptions of the stakeholders. Minimally interpretive analysis of the data resulted in identification of five themes: (i) general overview of LP's individual qualities; (ii) preconceived notions of the post; (iii) reality of the post; (iv) areas of concern; and (v) developing the role. The findings indicated that the LP role provides a credible and valuable link between theory and practice and, as such, is an important contribution to the modernization agenda of the NHS. It was apparent, however, that there are a number of areas in which developments are needed, and that organizational and individual actions are necessary in order to achieve the most from these posts.

A theory-based approach to understanding suicide risk in shelter-seeking women.

Wolford-Clevenger, Caitlin; Smith, Phillip N

2015-04-01

Women seeking shelter from intimate partner violence are at an increased risk for suicide ideation and attempts compared to women in the general population. Control-based violence, which is common among shelter-seeking women, may play a pivotal role in the development of suicide ideation and attempts. Current risk assessment and management practices for shelter-seeking women are limited by the lack of an empirically grounded understanding of increased risk in this population. We argue that in order to more effectively promote risk assessment and management, an empirically supported theory that is sensitive to the experiences of shelter-seeking women is needed. Such a theory-driven approach has the benefits of identifying and prioritizing targetable areas for intervention. Here, we review the evidence for the link between coercive control and suicide ideation and attempts from the perspective of Baumeister's escape theory of suicide. This theory has the potential to explain the role of coercive control in the development of suicide ideation and eventual attempts in shelter-seeking women. Implications for suicide risk assessment and prevention in domestic violence shelters are discussed. © The Author(s) 2014.

The effective theory of shift-symmetric cosmologies

Finelli, Bernardo; Goon, Garrett; Pajer, Enrico; Santoni, Luca

2018-05-01

A shift symmetry is a ubiquitous ingredient in inflationary models, both in effective constructions and in UV-finite embeddings such as string theory. It has also been proposed to play a key role in certain Dark Energy and Dark Matter models. Despite the crucial role it plays in cosmology, the observable, model independent consequences of a shift symmetry are yet unknown. Here, assuming an exact shift symmetry, we derive these consequences for single-clock cosmologies within the framework of the Effective Field Theory of Inflation. We find an infinite set of relations among the otherwise arbitrary effective coefficients, which relate non-Gaussianity to their time dependence. For example, to leading order in derivatives, these relations reduce the infinitely many free functions in the theory to just a single one. Our Effective Theory of shift-symmetric cosmologies describes, among other systems, perfect and imperfect superfluids coupled to gravity and driven superfluids in the decoupling limit. Our results are the first step to determine observationally whether a shift symmetry is at play in the laws of nature and whether it is broken by quantum gravity effects.

The role of self-regulatory efficacy, moral disengagement and guilt on doping likelihood: A social cognitive theory perspective.

PubMed

Ring, Christopher; Kavussanu, Maria

2018-03-01

Given the concern over doping in sport, researchers have begun to explore the role played by self-regulatory processes in the decision whether to use banned performance-enhancing substances. Grounded on Bandura's (1991) theory of moral thought and action, this study examined the role of self-regulatory efficacy, moral disengagement and anticipated guilt on the likelihood to use a banned substance among college athletes. Doping self-regulatory efficacy was associated with doping likelihood both directly (b = -.16, P < .001) and indirectly (b = -.29, P < .001) through doping moral disengagement. Moral disengagement also contributed directly to higher doping likelihood and lower anticipated guilt about doping, which was associated with higher doping likelihood. Overall, the present findings provide evidence to support a model of doping based on Bandura's social cognitive theory of moral thought and action, in which self-regulatory efficacy influences the likelihood to use banned performance-enhancing substances both directly and indirectly via moral disengagement.

The role of scripts in psychological maladjustment and psychotherapy.

PubMed

Demorest, Amy P

2013-12-01

This article considers the value of script theory for understanding psychological maladjustment and psychotherapy. Scripts are implicit expectations that individuals develop to understand and deal with emotionally significant life experiences. Script theory provides a way to understand the complex patterns of thinking, feeling, and behavior that characterize personal consistency, as well as a way to address personality development and change. As such it is a vital model for understanding both personality and clinical phenomena. The article begins by describing script theory and noting similar models in personality and clinical psychology. It then outlines both idiographic and nomothetic methods for assessing scripts and discusses the strengths and weaknesses of each. A survey of the author's program of research follows, using a nomothetic method to examine the role of interpersonal scripts in psychological maladjustment and psychotherapy. The article concludes by presenting a promising method for future research synthesizing idiographic and nomothetic approaches and raising important questions for future research on the role of scripts in psychological maladjustment and psychotherapy. © 2012 Wiley Periodicals, Inc.

Maintaining equilibrium in professional role identity: a grounded theory study of health visitors' perceptions of their changing professional practice context.

PubMed

Machin, Alison I; Machin, Tony; Pearson, Pauline

2012-07-01

This article reports the study of a group of United Kingdom health visitors' interactions with their changing practice context, focusing on role identity and influences on its stability. United Kingdom policies have urged health visitors to refocus their role as key public health nurses. Reduced role identity clarity precipitated the emergence of different models of health visiting public health work. An inconsistent role standard can lead to role identity fragmentation and conflict across a group. It may precipitate individual role crisis, affecting optimum role performance. Seventeen health visitors in two United Kingdom community healthcare organizations participated in a grounded theory study, incorporating constant comparative analysis. Direct observations and individual interviews were undertaken between 2002 and 2008. Four interlinked categories emerged: professional role identity (core category); professional role in action; interprofessional working; and local micro-systems for practice; each influencing participants' sense of identity and self-worth. The Role Identity Equilibrium Process explains interactive processes occurring at different levels of participants' practice. Re-establishing equilibrium and consistency in health visiting identity is a priority. This study's findings have significance for other nurses and health professionals working in complex systems, affected by role change and challenges to role identity. © 2011 Blackwell Publishing Ltd.

Gauge Theory on a Space with Linear Lie Type Fuzziness

NASA Astrophysics Data System (ADS)

Khorrami, Mohammad; Fatollahi, Amir H.; Shariati, Ahmad

2013-03-01

The U(1) gauge theory on a space with Lie type noncommutativity is constructed. The construction is based on the group of translations in Fourier space, which in contrast to space itself is commutative. In analogy with lattice gauge theory, the object playing the role of flux of field strength per plaquette, as well as the action, is constructed. It is observed that the theory, in comparison with ordinary U(1) gauge theory, has an extra gauge field component. This phenomena is reminiscent of similar ones in formulation of SU(N) gauge theory in space with canonical noncommutativity, and also appearance of gauge field component in discrete direction of Connes' construction of the Standard Model.

Ideology and gender: observers' system justification and targets' gender as interactive predictors of citizenship expectations.

PubMed

Chiaburu, Dan S; Harris, T Brad; Smith, Troy A

2014-01-01

We integrate system justification and social role theory to explain how observers' system justification and target employees' gender interact to predict observers' expectations of targets' sportsmanship citizenship behaviors. In contrast with social role theory predictions, observers did not expect greater levels of sportsmanship from women compared to men. Yet observers expected more sportsmanship from women (a) when observers were ideologically motivated by gender-specific beliefs (gender-specific system justification; Study 1) and (b) when system justification was cued experimentally (Study 2). A heretofore-unexamined aspect, observers' ideology, modifies their expectations of sportsmanship citizenship across target genders. This has implications for system justification, social role, and organizational citizenship theoretical perspectives.

U.S. Muslim women and body image: links among objectification theory constructs and the hijab.

PubMed

Tolaymat, Lana D; Moradi, Bonnie

2011-07-01

This study tested tenets of objectification theory and explored the role of the hijab in body image and eating disorder symptoms with a sample of 118 Muslim women in the United States. Results from a path analysis indicated that individual differences in wearing the hijab were related negatively with reported sexual objectification experiences. Sexual objectification experiences, in turn, had significant positive indirect relations with body surveillance, body shame, and eating disorder symptoms, primarily through the mediating role of internalization. Internalization of cultural standards of beauty also had a significant positive direct relation with body shame and significant positive direct and indirect relations with eating disorder symptoms. By contrast, the direct and indirect relations of body surveillance were significant only when the role of internalization was constrained to 0 (i.e., eliminated), suggesting that internalization of cultural standards of beauty subsumed the hypothesized role of body surveillance in the model. Taken together, these results support some of the tenets of objectification theory with a sample of U.S. Muslim women, point to the importance of internalization of dominant cultural standards of beauty within that framework, and suggest the utility of considering individual differences in wearing the hijab among U.S. Muslim women.

Overloaded and stressed: A case study of women working in the health care sector.

PubMed

Stevenson, Maggie; Duxbury, Linda

2018-04-23

Although role overload has been shown to be prevalent and consequential, there has been little attempt to develop the associated theory. The fact that the consequences of role overload can be positive or negative implies that the relationship between role overload and perceived stress depends partly on the environment within which role overload is experienced (i.e., the perceived situation) and how the situation is evaluated (i.e., appraised). Guided by cognitive appraisal theory, this study applies qualitative methodology to identify the situation properties that contribute to variable stress reactions to role overload. In this in-depth examination, overloaded female hospital workers were asked to describe what makes role overload situations potentially stressful, to gain an insight into how role overload is appraised. A taxonomy listing 12 role overload situation properties was developed from the findings, providing the first known classification of the situation properties of role overload that can create the potential for stress. The results also reveal clues as to why some people suffer more stress during role overload than others, increase our understanding of the relationship between role overload and perceived stress, and provide a useful tool for examining the environment of role overload.

Microscopic theory of cation exchange in CdSe nanocrystals.

Ott, Florian D; Spiegel, Leo L; Norris, David J; Erwin, Steven C

2014-10-10

Although poorly understood, cation-exchange reactions are increasingly used to dope or transform colloidal semiconductor nanocrystals (quantum dots). We use density-functional theory and kinetic Monte Carlo simulations to develop a microscopic theory that explains structural, optical, and electronic changes observed experimentally in Ag-cation-exchanged CdSe nanocrystals. We find that Coulomb interactions, both between ionized impurities and with the polarized nanocrystal surface, play a key role in cation exchange. Our theory also resolves several experimental puzzles related to photoluminescence and electrical behavior in CdSe nanocrystals doped with Ag.

The role of heuristic appraisal in conflicting assessments of string theory

NASA Astrophysics Data System (ADS)

Camilleri, Kristian; Ritson, Sophie

2015-08-01

Over the last three decades, string theory has emerged as one of the leading hopes for a consistent theory of quantum gravity that unifies particle physics with general relativity. Despite the fact that string theory has been a thriving research program for the better part of three decades, it has been subjected to extensive criticism from a number of prominent physicists. The aim of this paper is to obtain a clearer picture of where the conflict lies in competing assessments of string theory, through a close reading of the argumentative strategies employed by protagonists on both sides. Although it has become commonplace to construe this debate as stemming from different attitudes to the absence of testable predictions, we argue that this presents an overly simplified view of the controversy, which ignores the critical role of heuristic appraisal. While string theorists and their defenders see the theoretical achievements of the string theory program as providing strong indication that it is 'on the right track', critics have challenged such claims, by calling into question the status of certain 'solved problems' and its purported 'explanatory coherence'. The debates over string theory are therefore particularly instructive from a philosophical point of view, not only because they offer important insights into the nature of heuristic appraisal and theoretical progress, but also because they raise deep questions about what constitutes a solved problem and an explanation in fundamental physics.

Dust in magnetised plasmas - Basic theory and some applications. [to planetary rings

Northrop, T. G.; Morfill, G. E.

1984-01-01

In this paper the theory of charged test particle motion in magnetic fields is reviewed. This theory is then extended to charged dust particles, for which gravity and charge fluctuations play an important role. It is shown that systematic drifts perpendicular to the magnetic field and stochastic transport effects may then have to be considered none of which occur in the case of atomic particles (with the exception of charge exchange reactions). Some applications of charged dust particle transport theory to planetary rings are then briefly discussed.

A superstring field theory for supergravity

NASA Astrophysics Data System (ADS)

Reid-Edwards, R. A.; Riccombeni, D. A.

2017-09-01

A covariant closed superstring field theory, equivalent to classical tendimensional Type II supergravity, is presented. The defining conformal field theory is the ambitwistor string worldsheet theory of Mason and Skinner. This theory is known to reproduce the scattering amplitudes of Cachazo, He and Yuan in which the scattering equations play an important role and the string field theory naturally incorporates these results. We investigate the operator formalism description of the ambitwsitor string and propose an action for the string field theory of the bosonic and supersymmetric theories. The correct linearised gauge symmetries and spacetime actions are explicitly reproduced and evidence is given that the action is correct to all orders. The focus is on the NeveuSchwarz sector and the explicit description of tree level perturbation theory about flat spacetime. Application of the string field theory to general supergravity backgrounds and the inclusion of the Ramond sector are briefly discussed.

2007-05-01

Microbial ecology is currently undergoing a revolution, with repercussions spreading throughout microbiology, ecology and ecosystem science. The rapid accumulation of molecular data is uncovering vast diversity, abundant uncultivated microbial groups and novel microbial functions. This accumulation of data requires the application of theory to provide organization, structure, mechanistic insight and, ultimately, predictive power that is of practical value, but the application of theory in microbial ecology is currently very limited. Here we argue that the full potential of the ongoing revolution will not be realized if research is not directed and driven by theory, and that the generality of established ecological theory must be tested using microbial systems.

Stuck on semantics: Processing of irrelevant object-scene inconsistencies modulates ongoing gaze behavior.

PubMed

Cornelissen, Tim H W; Võ, Melissa L-H

2017-01-01

People have an amazing ability to identify objects and scenes with only a glimpse. How automatic is this scene and object identification? Are scene and object semantics-let alone their semantic congruity-processed to a degree that modulates ongoing gaze behavior even if they are irrelevant to the task at hand? Objects that do not fit the semantics of the scene (e.g., a toothbrush in an office) are typically fixated longer and more often than objects that are congruent with the scene context. In this study, we overlaid a letter T onto photographs of indoor scenes and instructed participants to search for it. Some of these background images contained scene-incongruent objects. Despite their lack of relevance to the search, we found that participants spent more time in total looking at semantically incongruent compared to congruent objects in the same position of the scene. Subsequent tests of explicit and implicit memory showed that participants did not remember many of the inconsistent objects and no more of the consistent objects. We argue that when we view natural environments, scene and object relationships are processed obligatorily, such that irrelevant semantic mismatches between scene and object identity can modulate ongoing eye-movement behavior.

Attentional networks in developmental dyscalculia

PubMed Central

2010-01-01

Background Very little is known about attention deficits in developmental dyscalculia, hence, this study was designed to provide the missing information. We examined attention abilities of participants suffering from developmental dyscalculia using the attention networks test - interactions. This test was designed to examine three different attention networks--executive function, orienting and alerting--and the interactions between them. Methods Fourteen university students that were diagnosed as suffering from developmental dyscalculia--intelligence and reading abilities in the normal range and no indication of attention-deficit hyperactivity disorder--and 14 matched controls were tested using the attention networks test - interactions. All participants were given preliminary tests to measure mathematical abilities, reading, attention and intelligence. Results The results revealed deficits in the alerting network--a larger alerting effect--and in the executive function networks--a larger congruity effect in developmental dyscalculia participants. The interaction between the alerting and executive function networks was also modulated by group. In addition, developmental dyscalculia participants were slower to respond in the non-cued conditions. Conclusions These results imply specific attentional deficits in pure developmental dyscalculia. Namely, those with developmental dyscalculia seem to be deficient in the executive function and alertness networks. They suffer from difficulty in recruiting attention, in addition to the deficits in numerical processing. PMID:20157427

Reduction and internal fixation of displaced intra-articular calcaneal fractures with a locking nail: a prospective study of sixty nine cases.

2015-10-01

The best treatment for intra-articular fractures of the calcaneus is still debated. The aims of this study were to determine whether intrafocal reduction of thalamic fractures is effective, to evaluate whether a locking nail is able to maintain reduction of the articular surface and to analyse the functional results of this original method. This prospective study assessed 69 fractures treated with a locking fracture nail in 63 cases and with primary subtalar fusion in six (Calcanail (®), FH). Articular congruity and global reduction of the calcaneus was assessed in all patients by computed tomography (CT) scan three months postoperatively. Functional results were evaluated according to the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Score (AOFAS-AHS) and all complications recorded. For the 63 fracture nails, the average AOFAS score was 85.9 at a mean final follow-up of 12 months. Only three secondary fusions were performed. For the six comminuted fractures requiring primary fusion, the average AOFAS score was 75.9 at the last follow-up. The posterior intrafocal approach for both reduction and locked nailing of intra-articular calcaneal fractures has been proven as an effective and reliable procedure.

Theory and practice of clinical ethics support services: narrative and hermeneutical perspectives.

PubMed

Porz, Rouven; Landeweer, Elleke; Widdershoven, Guy

2011-09-01

In this paper we introduce narrative and hermeneutical perspectives to clinical ethics support services (CESS). We propose a threefold consideration of 'theory' and show how it is interwoven with 'practice' as we go along. First, we look at theory in its foundational role: in our case 'narrative ethics' and 'philosophical hermeneutics' provide a theoretical base for clinical ethics by focusing on human identities entangled in stories and on moral understanding as a dialogical process. Second, we consider the role of theoretical notions in helping practitioners to understand their situation in clinical ethics practice, by using notions like 'story', 'responsibility', or 'vulnerability' to make explicit and explain their practical experience. Such theoretical notions help us to interpret clinical situations from an ethical perspective and to foster moral awareness of practitioners. And, thirdly, we examine how new theoretical concepts are developed by interpreting practice, using practice to form and improve our ethical theory. In this paper, we discuss this threefold use of theory in clinical ethics support services by reflecting on our own theoretical assumptions, methodological steps and practical experiences as ethicists, and by providing examples from our daily work. In doing so, we illustrate that theory and practice are interwoven, as theoretical understanding is dependent upon practical experience, and vice-versa. © 2011 Blackwell Publishing Ltd.

Why we need a theory of suffering, and lots of other theories as well: commentary.

PubMed

Churchill, Larry R

1991-01-01

In the first section of his article, "The Role of Suffering and Community in Clinical Ethics," Erich Loewy sketches a theory of suffering. His conviction is that clinical medical ethics is not clearly rooted in theory and is inadequately grounded because of this. While acknowledging the merits of virtue ethics and casuistry, Loewy quickly dispenses with them, as contenders for this theoretical basis. Kantianism and utilitarianism are likewise rejected as "a universally acceptable grounding for ethics." In their place, Loewy proposes that "a deeper and more universal grounding can be found in the capacity of sentient beings to suffer." It is on this capacity to suffer that he builds his hierarchies of moral value, including primary, secondary, and symbolic worth. This theory of suffering should be welcomed. It promises to expand our awareness of clinical experience, and moral life generally, away from autonomy, utility, or virtue orientations toward attention to suffering and our response to it. Such a theory can give us a revitalized language to probe the issues of medical ethics. This should lead us to a careful reading of Loewy's larger work on which this article is based. Yet my enthusiasm is tempered by Loewy's noncritical acceptance of a peculiar, yet pervasive, understanding of the role and use of theory in ethics....

Entrepreneurship education revisited: perceived entrepreneurial role models increase perceived behavioural control.

PubMed

Fellnhofer, Katharina

2017-01-01

Relying on Bandura's (1986) social learning theory, Ajzen's (1988) theory of planned behaviour (TPB), and Dyer's (1994) model of entrepreneurial careers, this study aims to highlight the potential of entrepreneurial role models to entrepreneurship education. The results suggest that entrepreneurial courses would greatly benefit from real-life experiences, either positive or negative. The results of regression analysis based on 426 individuals, primarily from Austria, Finland, and Greece, show that role models increase learners' entrepreneurial perceived behaviour control (PBC) by increasing their self-efficacy. This study can inform the research and business communities and governments about the importance of integrating entrepreneurs into education to stimulate entrepreneurial PBC. This study is the first of its kind using its approach, and its results warrant more in-depth studies of storytelling by entrepreneurial role models in the context of multimedia entrepreneurship education.

We apply BRST method to the self-dual Chern-Simons gauge theory with matter fields and the generators of symmetries of the system from an elegant Lie algebra structure under the operation of Poisson bracket. We discuss four different cases: abelian, nonabelian, relativistic, and nonrelativistic situations and extend the system to the whole phase space including ghost fields. In addition, we obtain the BRST charge of the field system and check its nilpotence of the BRST transformation which plays an important role such as in topological quantum field theory and string theory.

Quantum learning is a combination of many interactions that exist during learning. This model can be applied by current interesting topic, contextual, repetitive, and give opportunities to students to demonstrate their abilities. The basis of the quantum learning model are left brain theory, right brain theory, triune, visual, auditorial, kinesthetic, game, symbol, holistic, and experiential learning theory. Creativity plays an important role to be success in the working world. Creativity shows alternatives way to problem-solving or creates something. Good memory plays a role in the success of learning. Through quantum learning, students will use all of their abilities, interested in learning and create their own ways of memorizing concepts of the material being studied. From this idea, researchers assume that quantum learning models can improve creativity and memory of the students.

Based on role stress theory, we posit that passive leadership will predict higher levels of role ambiguity, role conflict and role overload. Invoking Conservation of Resources theory, we further hypothesize that these role stressors will indirectly and negatively influence two aspects of employee well-being, namely overall mental health and overall work attitude, through psychological work fatigue. Using a probability sample of 2467 US workers, structural equation modelling supported the model by showing that role stressors and psychological work fatigue partially mediated the negative relationship between passive leadership and both aspects of employee well-being. The hypothesized, sequential indirect relationships explained 47.9% of the overall relationship between passive leadership and mental health and 26.6% of the overall relationship between passive leadership and overall work attitude.

Exploration of Effective Persuasive Strategies Used in Resisting Product Advertising: A Case Study of Adult Health Check-Ups.

PubMed

Tien, Han-Kuang; Chung, Wen

2018-05-10

This research addressed adults' health check-ups through the lens of Role Transportation Theory. This theory is applied to narrative advertising that lures adults into seeking health check-ups by causing audiences to empathize with the advertisement's character. This study explored the persuasive mechanism behind narrative advertising and reinforced the Protection Motivation Theory model. We added two key perturbation variables: optimistic bias and truth avoidance. To complete the verification hypothesis, we performed two experiments. In Experiment 1, we recruited 77 respondents online for testing. We used analyses of variance to verify the effectiveness of narrative and informative advertising. Then, in Experiment 2, we recruited 228 respondents to perform offline physical experiments and conducted a path analysis through structural equation modelling. The findings showed that narrative advertising positively impacted participants' disease prevention intentions. The use of Role Transportation Theory in advertising enables the audience to be emotionally connected with the character, which enhances persuasiveness. In Experiment 2, we found that the degree of role transference can interfere with optimistic bias, improve perceived health risk, and promote behavioral intentions for health check-ups. Furthermore, truth avoidance can interfere with perceived health risks, which, in turn, reduce behavioral intentions for health check-ups.

Vargas-Salfate, Salvador; Paez, Dario; Liu, James H; Pratto, Felicia; Gil de Zúñiga, Homero

2018-07-01

This study tests specific competing hypotheses from social dominance theory/realistic conflict theory (RCT) versus system justification theory about the role of social status. In particular, it examines whether system justification belief and effects are stronger among people with low socioeconomic status, and in less socially developed and unequal nations than among better-off people and countries. A cross-national survey was carried out in 19 nations from the Americas, Western and Eastern Europe, Asia, and Oceania using representative online samples ( N = 14,936, 50.15% women, M age = 41.61 years). At the individual level, system justification beliefs, right-wing authoritarianism, social dominance orientation, national identification, sociopolitical conservatism, sex, age, and social status were measured. At the national level, the human development index and the Gini index were used. Multilevel analyses performed indicated that results fit better with the social dominance/RCT approach, as system justification was higher in high-status and developed nations; further, associations between legitimizing ideologies and system justification were stronger among high-status people.

Biology is more theoretical than physics.

PubMed

Gunawardena, Jeremy

2013-06-01

The word "theory" is used in at least two senses--to denote a body of widely accepted laws or principles, as in "Darwinian theory" or "quantum theory," and to suggest a speculative hypothesis, often relying on mathematical analysis, that has not been experimentally confirmed. It is often said that there is no place for the second kind of theory in biology and that biology is not theoretical but based on interpretation of data. Here, ideas from a previous essay are expanded upon to suggest, to the contrary, that the second kind of theory has always played a critical role and that biology, therefore, is a good deal more theoretical than physics.

Relaxation approximation in the theory of shear turbulence

NASA Technical Reports Server (NTRS)

Rubinstein, Robert

1995-01-01

Leslie's perturbative treatment of the direct interaction approximation for shear turbulence (Modern Developments in the Theory of Turbulence, 1972) is applied to derive a time dependent model for the Reynolds stresses. The stresses are decomposed into tensor components which satisfy coupled linear relaxation equations; the present theory therefore differs from phenomenological Reynolds stress closures in which the time derivatives of the stresses are expressed in terms of the stresses themselves. The theory accounts naturally for the time dependence of the Reynolds normal stress ratios in simple shear flow. The distortion of wavenumber space by the mean shear plays a crucial role in this theory.

[THE ROLE OF PHILOSOPHICAL REFLECTIONS OF STANISLAW ZAREMBA IN THE CONTEXT OF A DISPUTE ON THE FOUNDATIONS OF THE THEORY OF RELATIVITY].

PubMed

Polak, Paweł

2014-01-01

The aim of this paper is to present the philosophical background of Stanisław Zaremba's critique of Einstein's theory of relativity. In the 1920s, Zaremba was the most prominent Polish opponent of this theory. His papers influenced some discussions related to Einstein's theory, especially in France and in Poland. This paper takes also into account the development of Zaremba's critique. The analysis of his papers shows that he never became a follower of the Einstein's theory of relativity. Such a statement compels us to confront it with the previous interpretations of Zaremba's thought.

2017-11-10

Stepgrandparents are becoming more common, and they can, and often do, provide affective and instrumental support to families. Little is known, however, about how they negotiate and enact their roles within families, especially with stepgrandchildren. Stepgrandmothers warrant special attention because researchers have found that women experience more challenges than men in stepfamilies. Guided by symbolic interactionism, the purposes of our study were: (a) to explore stepgrandmothers' role enactment and (b) to explore the intrapersonal, interpersonal, and contextual factors that contribute to role enactment in intergenerational steprelationships. Eighteen stepgrandmothers participated in semi-structured interviews, discussing their relationships with 94 stepgrandchildren. Consistent with grounded theory methods, data collection and analysis occurred simultaneously. Interviews with stepgrandmothers revealed that they spend considerable time and energy defining their roles with stepgrandchildren. Stepgrandmothers' role enactment is a complex, reflexive process. A few perceived that their roles were shaped by their own dispositions, desires, and expectations (evidence for role-making), but most stepgrandmothers described their roles as reflecting the dispositions, desires, and expectations of others (evidence for role-taking). Stepgrandmothers reflected on their roles as a delicate balance of intra- and inter-personal negotiations, operating within cultural expectations. Findings draw attention to the complex nature of role-taking, role-making, and gendered, relational processes in multigenerational stepfamilies. We discuss implications for research and theory related to stepgrandmotherhood as an incomplete institution. © The Author 2016.

Joel Hillhouse, Guy Cafri; Thompson, J Kevin; Jacobsen, Paul B; Hillhouse, Joel

2009-12-01

UV exposure via sunbathing and utilization of sun lamps and tanning beds are considered important risk factors for the development of skin cancer. Psychosocial models of UV exposure are often based on theories of health behavior, but theory from the body image field can be useful as well. The current study examines models that prospectively predict sunbathing and indoor tanning behaviors using constructs and interrelationships derived from the tripartite theory of body image, theory of reasoned action, health belief model, revised protection motivation theory, and a proposed integration of several health behavior models. The results generally support a model in which intentions mediate the relationship between appearance attitudes and tanning behaviors, appearance reasons to tan and intentions mediate the relationship between sociocultural influences and tanning behaviors, and appearance reasons not to tan and intentions mediate the role of perceived threat on behaviors. The implications of these findings are considered. © Springer Science+Business Media, LLC 2009

Representing the Electromagnetic Field: How Maxwell's Mathematics Empowered Faraday's Field Theory

NASA Astrophysics Data System (ADS)

Tweney, Ryan D.

2011-07-01

James Clerk Maxwell `translated' Michael Faraday's experimentally-based field theory into the mathematical representation now known as `Maxwell's Equations.' Working with a variety of mathematical representations and physical models Maxwell extended the reach of Faraday's theory and brought it into consistency with other results in the physics of electricity and magnetism. Examination of Maxwell's procedures opens many issues about the role of mathematical representation in physics and the learning background required for its success. Specifically, Maxwell's training in `Cambridge University' mathematical physics emphasized the use of analogous equations across fields of physics and the repeated solving of extremely difficult problems in physics. Such training develops an array of overlearned mathematical representations supported by highly sophisticated cognitive mechanisms for the retrieval of relevant information from long term memory. For Maxwell, mathematics constituted a new form of representation in physics, enhancing the formal derivational and calculational role of mathematics and opening a cognitive means for the conduct of `experiments in the mind' and for sophisticated representations of theory.

Becoming Therapeutic Agents: A Grounded Theory of Mothers' Process When Implementing Cognitive Behavioural Therapy at Home with an Anxious Child.

PubMed

Pishva, Rana

2017-05-01

The premise of parent-centred programmes for parents of anxious children is to educate and train caregivers in the sustainable implementation of cognitive behaviour therapy (CBT) in the home. The existing operationalization of parent involvement, however, does not address the systemic, parent or child factors that could influence this process. The qualitative approach of grounded theory was employed to examine patterns of action and interaction involved in the complex process of carrying out CBT with one's child in one's home. A grounded theory goes beyond the description of a process, offering an explanatory theory that brings taken-for-granted meanings and processes to the surface. The theory that emerged from the analysis suggests that CBT implementation by mothers of anxious children is characterized by the evolution of mothers' perception of their child and mothers' perception of their role as well as a shift from reacting with emotion to responding pragmatically to the child. Changes occur as mothers recognize the crisis, make links between the treatment rationale, child's symptoms and their own parenting strategies, integrate tenets of CBT for anxiety and eventually focus on sustaining therapeutic gains through natural life transitions. The theory widens our understanding of mothers' role, therapeutic engagement, process, and decision-making. The theory also generates new hypotheses regarding parent involvement in the treatment of paediatric anxiety disorders and proposes novel research avenues that aim to maximize the benefits of parental involvement in the treatment of paediatric anxiety disorders. Copyright © 2016 John Wiley & Sons, Ltd. Mothers of anxious youth who take part in parent-centred programmes experience a shift in their perception of the child and of their role. Parental strategy after CBT implementation shifts from emotional empathy to cognitive empathy. Mothers experience significant challenges and require additional support in prevention of relapse and knowledge translation. Copyright © 2016 John Wiley & Sons, Ltd.

One of the key strategies in students’ learning is being affected by models. Understanding the role-modeling process in education will help to make greater use of this training strategy. The aim of this grounded theory study was to explore Iranian nursing students and instructors’ experiences about role modeling process. Data was analyzed by Glaserian’s Grounded Theory methodology through semi-structured interviews with 7 faculty members, 2 nursing students; the three focus group discussions with 20 nursing students based on purposive and theoretical sampling was done for explaining role modeling process from four nursing faculties in Tehran. Through basic coding, an effort to comprehensive growth and excellence was made with the basic social process consisting the core category and through selective coding three phases were identified as: realizing and exposure to inadequate human and professional growth, facilitating human and professional growth and evolution. The role modeling process is taking place unconscious, involuntary, dynamic and with positive progressive process in order to facilitate overall growth in nursing student. Accordingly, the design and implementation of the designed model can be used to make this unconscious to conscious, active and voluntarily processes a process to help education administrators of nursing colleges and supra organization to prevent threats to human and professional in nursing students’ education and promote nursing students’ growth.

New two-metric theory of gravity with prior geometry

NASA Technical Reports Server (NTRS)

Lightman, A. P.; Lee, D. L.

1973-01-01

A Lagrangian-based metric theory of gravity is developed with three adjustable constants and two tensor fields, one of which is a nondynamic 'flat space metric' eta. With a suitable cosmological model and a particular choice of the constants, the 'post-Newtonian limit' of the theory agrees, in the current epoch, with that of general relativity theory (GRT); consequently the theory is consistent with current gravitation experiments. Because of the role of eta, the gravitational 'constant' G is time-dependent and gravitational waves travel null geodesics of eta rather than the physical metric g. Gravitational waves possess six degrees of freedom. The general exact static spherically-symmetric solution is a four-parameter family. Future experimental tests of the theory are discussed.

Picture superiority doubly dissociates the ERP correlates of recollection and familiarity.

PubMed

Curran, Tim; Doyle, Jeanne

2011-05-01

Two experiments investigated the processes underlying the picture superiority effect on recognition memory. Studied pictures were associated with higher accuracy than studied words, regardless of whether test stimuli were words (Experiment 1) or pictures (Experiment 2). Event-related brain potentials (ERPs) recorded during test suggested that the 300-500 msec FN400 old/new effect, hypothesized to be related to familiarity-based recognition, benefited from study/test congruity, such that it was larger when study and test format remained constant than when they differed. The 500-800 msec parietal old/new effect, hypothesized to be related to recollection, benefited from studying pictures, regardless of test format. The parallel between the accuracy and parietal ERP results suggests that picture superiority may arise from encoding the distinctive attributes of pictures in a manner that enhances their later recollection. Furthermore, when words were tested, opposite effects of studying words versus studying pictures were observed on the FN400 (word > picture) versus parietal (picture > word) old/new effects--providing strong evidence for a crossover interaction between these components that is consistent with a dual-process perspective.

Taiwanese immigrant mothers' childcare preferences: socialization for bicultural competency.

PubMed

Uttal, Lynet; Han, Ching Yun

2011-10-01

This paper explores how middle-class Taiwanese immigrant mothers in the United States defined the benefits of placing their children in predominantly White American childcare centers instead of using more culturally familiar forms of care. From in-depth interviews with seven Taiwanese immigrant mothers, it was learned that they viewed these settings positively, even though their children were not in cultural environments that mirrored their homes and ethnic communities. Mothers explained that they purposefully chose this type of setting because 1) they desired to develop their children's social competency in U.S. society; 2) they perceived U.S. childcare settings as multicultural and accepting of diverse cultures even if they were in the minority; and 3) they were confident that their children's participation in their own Taiwanese ethnic community would ensure the maintenance of their children's ethnic identity and knowledge of their parents' culture. For these reasons, they did not seek out race matching or cultural congruity between childcare centers and their homes. Instead, mothers viewed the childcare center as part of their overall socialization strategy for developing their children's bicultural competency in both their heritage culture as well as U.S. society.

Logical recoding of S-R rules can reverse the effects of spatial S-R correspondence.

PubMed

Wühr, Peter; Biebl, Rupert

2009-02-01

Two experiments investigated competing explanations for the reversal of spatial stimulus-response (S-R) correspondence effects (i.e., Simon effects) with an incompatible S-R mapping on the relevant, nonspatial dimension. Competing explanations were based on generalized S-R rules (logical-recoding account) or referred to display-control arrangement correspondence or to S-S congruity. In Experiment 1, compatible responses to finger-name stimuli presented at left/right locations produced normal Simon effects, whereas incompatible responses to finger-name stimuli produced an inverted Simon effect. This finding supports the logical-recoding account. In Experiment 2, spatial S-R correspondence and color S-R correspondence were varied independently, and main effects of these variables were observed. The lack of an interaction between these variables, however, disconfirms a prediction of the display-control arrangement correspondence account. Together, the results provide converging evidence for the logical-recoding account. This account claims that participants derive generalized response selection rules (e.g., the identity or reversal rule) from specific S-R rules and inadvertently apply the generalized rules to the irrelevant (spatial) S-R dimension when selecting their response.

We point out the relation of our approach, which is based on an ontology of a concept as an entity in a state changing under influence of a context, with the main traditional concept theories, that is, prototype theory, exemplar theory, and theory theory. We ponder about the question why quantum theory performs so well in its modeling of human concepts, and we shed light on this question by analyzing the role of complex amplitudes, showing how they allow to describe interference in the statistics of measurement outcomes, while in the traditional theories statistics of outcomes originates in classical probability weights, without the possibility of interference. The relevance of complex numbers, the appearance of entanglement, and the role of Fock space in explaining contextual emergence, all as unique features of the quantum modeling, are explicitly revealed in this article by analyzing human concepts and their dynamics. © 2013 Cognitive Science Society, Inc.

Androgyny Versus Gender Schema: A Comment on Bem's Gender Schema Theory.

ERIC Educational Resources Information Center

Spence, Janet T.; Helmreich, Robert L.

1981-01-01

A logical contradiction in Bem's (1981) theory is outlined. The Bem Sex Role Inventory cannot measure a unidimensional construct, gender schema, and two independent constructs--masculinity and femininity. Such instruments measure self-images of instrumental and expressive personality traits which show little relationship to the constructs…
