Relative contributions to overall impact of stuttering in adults using the overall assessment of the Speaker’s Experience of Stuttering (OASES)

PurposeComprehensive assessment of stuttering requires consideration of a wide range of behaviors that impact outcomes, and the Overall Assessment of the Speaker’s Experience of Stuttering (OASES) is an assessment tool that accomplishes such. The purpose of this study was to determine how the individual components of the test contribute to the OASES’ impact score.MethodData collected at a university speech-language and hearing clinic from 29 adults were used for a relative weight analysis (RWA). RWA was utilized to determine the relative contributions of the OASES’ subtests to the OASES’ impact score. Confidence intervals for the individual relative weights were calculated for each OASES subtest and significance tests based on bootstrapping with 10,000 replications.ResultsDifferences were present in contributions of the OASES’ subtests to the OASES’ overall impact score, where the following explained a significant amount of variance in the OASES’ impact score: Speaker’s Reactions; Daily Communication; and Quality of Life. However, contribution of the subtest, “General Information”, was not significant.ConclusionThrough examination of relative contributions to the impact of stuttering using the OASES, this project has identified differences in contributors to the overall impact of the disorder of stuttering. This information is beneficial to researchers and clinicians alike in that it gives specific guidance into what determines increased impact in adults who stutter (AWS). Future works should pursue clarification of these differences with an end goal of identifying and overcoming barriers to positive outcomes while also identifying and nurturing facilitators to optimal management.     

Authorship Decision Making: An Empirical Investigation

This empirical study concerns the authorship credit decision-making processes and outcomes that occur among coauthors in cases of multiauthored publications. The 2002 American Psychological Association (APA) Ethics Code offers standards for determining authorship order; however, little is known about how these decisions are made in actual practice. Results from a survey of 109 randomly selected authors indicated that most authors were satisfied with the decision-making process and outcome with few disagreements. Participants reported cases of both undeserved authorship being given and omission of deserving contributors' names as coauthors. Some factors associated with authorship decisions included “sense of loyalty or obligation,” “publish or perish pressures,” and “power differentials.” Authors who used APA standards were significantly more satisfied with both the process and outcome of authorship credit decisions.     

On the (numerical) ranking associated with any finite binary relation

We generalize the concept of a ‘ranking associated with a linear order’ from linear orders to arbitrary finite binary relations. Using the concept of differential of an object in a binary relation as theoretical primitive, we axiomatically introduce several measurement scales, some of which include the generalized ranking as a special case. We provide a computational formula for this generalized ranking, discuss its many elegant properties and offer some illustrating examples.     

一个参与者眼中的行为遗传学史上的里程碑

行为遗传学的历史,从横切面看,就好似一个由心理学、遗传学、生物学、进化论、人类学、人口学、生物统计、社会学以及法哲学等学科组合成的万花筒。任何一对学科的演进都呈正相关。虽然任何一对学科都不至于相互否定,但是,他们各自独特的历史和人物,又使得每一对学科并不完全相似     

Facets of the linear ordering polytope: A unification for the fence family through weighted graphs

The binary choice polytope appeared in the investigation of the binary choice problem formulated by Guilbaud and Block and Marschak. It is nowadays known to be the same as the linear ordering polytope from operations research (as studied by Grötschel, Jünger and Reinelt).The central problem is to find facet-defining linear inequalities for the polytope. Fence inequalities constitute a prominent class of such inequalities (Cohen and Falmagne; Grötschel, Jünger and Reinelt). Two different generalizations exist for this class: the reinforced fence inequalities of Leung and Lee, and independently Suck, and the stability-critical fence inequalities of Koppen. Together with the fence inequalities, these inequalities form the fence family. Building on previous work on the biorder polytope by Christophe, Doignon and Fiorini, we provide a new class of inequalities which unifies all inequalities from the fence family. The proof is based on a projection of polytopes. The new class of facet-defining inequalities is related to a specific class of weighted graphs, whose definition relies on a curious extension of the stability number. We investigate this class of weighted graphs which generalize the stability-critical graphs.     

Infant observation: A range of questions and challenges for contemporary psychoanalysis1

The author attempts to integrate several perspectives within the field of infant observation that reflect the analyst's personal experience as a clinician, as a professor at the analytic institute and as a researcher in the field of psychoanalysis. Can infant observation contribute to analytic technique, theory and training? If so, what would be the nature of such contribution? To answer these questions, the author reviews the literature on infant observation from Freud to the present, highlighting Latin American contributions to this subject. She makes reference to the role of technological innovations, which have allowed videotaping, repeated observations, temporal segmentation and computerized programs, thus giving rise to microanalytic research. This discussion prompts the question about the contributions made by systematic research to clinical practice. To tackle this question, the author presents both a clinical vignette taken from her personal experience, and the current debate on this subject as it appears in the work of Daniel Stern and André Green. Finally, she presents some conclusions that are part of an ongoing debate in the psychoanalytic field.     

Predicting stress patterns in an unpredictable stress language: The use of non-lexical sources of evidence for stress assignment in Russian

The main goal of this research was to examine how readers of Russian assign stress to disyllabic words. In particular, we tested the claim that the process of stress assignment in Russian can only be accomplished lexically. Eleven potential non-lexical sources of evidence for stress in Russian were examined in regression and factorial studies. In Study 1, onset complexity, coda complexity, the orthography of the first syllable (CVC1), of the second syllable (CVC2), and of the ending of the second syllable (VC2) were found to be probabilistically associated with stress in Russian disyllables. In Studies 2 and 3, it was shown that Russian speakers do use 3 of these cues (CVC1, CVC2, and VC2) when making stress-assignment decisions. These results provide evidence against the idea that the nature of stress in the Russian language is so unpredictable that stress assignment can only be accomplished lexically. These results also suggest that any successful model of stress assignment in Russian needs to contain mechanisms allowing these 3 orthographic cues to play a role in the stress-assignment process.     

Generative Concern, Political Commitment, and Charitable Actions

The implications of psychosocial generativity (Erikson, 1950) for understanding contemporary politics were explored. Study 1 replicated, in two samples, previous findings that generativity concerns are related to a variety of political activities, including the expenditure of time and money in support of political organizations. Using path analyses, Study 2 extended these findings and demonstrated how midlife generativity concerns interacted with political orientation and interest in politics to produce stronger relationships with giving. These findings suggest that people view the political arena as one important way to improve society and thereby manifest cultural generativity. Although focusing on the domain of politics, these studies highlight the complexity of generativity as a construct; broad concerns with generativity operate within the context of ideological commitments to produce greater levels of generative activity.     

A comparison of fathers' and mothers' contributions in the prediction of academic performance of school-age children in Hong Kong

Asystematic study of the linkages between gender issues and parenting is made among Chinese families. This study examines sex differences in parenting attributes across fathers and mothers and towards sons and daughters, and compares the contributions of fathers and mothers to the prediction of academic performance across boys and girls. Four parenting attributes are included: nurturance, psychological control, parental involvement in education, and parental academic efficacy. Data were collected from 461 Chinese father-mother-child triads of children studying Grade 3 to 5 in Hong Kong. Findings of this study, based on multivariate analysis of variance, showed that parental roles followed traditional Chinese cultural expectations. Compared to the fathers, Chinese mothers of school-age children in Hong Kong were more loving and caring, more involved in children's education, and more efficacious in promoting children's academic performance. Results of hierarchical regression analysis examining the role of child's sex as a moderator showed cross-sex influence in parental contribution to academic performance with respect to parental psychological control and academic efficacy. Specifically, boys benefited more from maternal efficacy than girls did and they were also more hampered by mothers with high psychological control, while girls' academic performance was more enhanced by paternal academic efficacy than boys. A gender-balance approach that highlights the significance of gender in moderating parental contributions to academic performance was thus supported. Future research should continue to focus on psychological control and domain-specific parental attributes as potential sources of gender-linked parent-child associations. Investigations should also explore other cognitive and noncognitive domains of child outcome, different child age groups, as well as Chinese populations in various geographical regions.
