14‐month‐olds exploit verbs’ syntactic contexts to build expectations about novel words

During their second year of life, infants develop a rudimentary understanding of grammatical categories based on their knowledge and use of frequent function words. The current study inquired whether, at only 14 months of age, infants can track co‐occurrence patterns between function words and content words (e.g., determiners can precede nouns, and pronouns can precede verbs), and use these previously encountered syntactic contexts to build expectations about which function words can co‐occur with novel words. Using a habituation paradigm, French‐learning 14‐month‐olds were presented with utterances containing two novel words preceded by function words (either two determiners in the Novel Nouns condition or two pronouns in the Novel Verbs conditions). We found that at test, infants looked longer during trials in which the novel words occurred in an unexpected syntactic context (following a pronoun for infants in the Novel Nouns condition and following a determiner for infants in the pooled analysis of the three Novel Verbs conditions). Hence, our results confirm previous findings on infants’ sensitivity to noun contexts and most importantly demonstrate that their sensitivity to the co‐occurrence of verbs with pronouns begins much earlier than previously understood.     

The Voice of the Child in Parenting Coordination: Views of Children,Parents, and Parenting Coordinators

This article examines the views of children, parents, and parenting coordinators (PCs) on child inclusion in the parenting coordination process. Participants in a parenting coordination pilot project in Montréal, Quebec—10 children (ranging in age from 8–17 years old), 14 parents, and 2 PCs—were interviewed at the end of the project. The goal was to understand their perceptions of child participation in parenting coordination interventions. Overall, a vast majority of children and parents agreed that children should be given a forum in parenting coordination and their voices heard. Feedback from PCs on their child inclusion experience also provided rare insight into this practice. Results confirm the importance for children of being heard in postseparation interventions, even when parental conflict is high. These findings add to the growing literature on the participation of children in postseparation interventions.     

Children’s perspectives on parenting coordination: Insights from the montreal parenting coordination pilot project

As part of a pilot project in the Montreal area, ten high-conflict families received free parenting coordination services. This explorative study aimed to document, through psychometric measures and semistructured interviews, how the parenting coordination process impacted children involved. Although not statistically significant, results suggest a diminution in the intensity of the conflict between parents over the course of parenting coordination, as perceived by the children. Qualitative data indicates variation in children’s opinions regarding their experience. Approximately half of the sample shared examples of improvements in their lives, mostly to do with diminution of parental conflict and better communication between parents. However, some shared frustrations with the intervention and their belief that parenting coordination was not helpful. Not feeling heard by the parenting coordinator (PC) as well as a perceived lack of neutrality were linked with negative discourse on parenting coordination.     

Clinical correlates and repetition of self-harming behaviors among female adolescent victims of sexual abuse

This study investigated self-harming behaviors in 149 female adolescent victims of sexual abuse, first, by determining the rates of nine types of self-mutilating behavior at intake and nine months later and, second, by investigating comorbidity of clinical correlates associated with these behaviors. The adolescents were divided into three groups according to level of self-mutilating behavior and then compared on symptom self-reports; 62.1% of the adolescents engaged in at least one self-mutilating behavior. A graded relation was observed between level of self-mutilating behavior and rate, and total number of clinical disorders. At nine month follow-up, one in four teenagers still reported a moderate or high level of self-harm. The need for systematic assessment and intervention of self-mutilating behaviors is discussed.     

Worldwide research output in probability and statistics: An update

The authors update the work of Genest (1997, 1999) on world research output in probability and statistics. The rankings they produce of countries and institutions are based on a survey of papers published between 1986 and 2000 in 25 specialized journals of high reputation in these two fields. The contribution of Canadian probabilists and statisticians is highlighted.     

The analysis of ordinal dispersion: A comparison of Leik's “D” with a variance formula

The frequency of ordinal data and the importance of attitudinal consensus in social research motivated Leik [Leik, R. L. (1966), Pacific Sociological Review 9, 85–90] to formulate a simple, effective measure of ordinal dispersion, but he did not provide a method for its statistical analysis, and its operational interpretation for nonextremal values is unclear. Leik's D is an equal-interval, “folded” scoring vector inner dot-product, scalar transformation of the vector of ordered relative frequencies. The folding point is the median category. The metric analog of D is the difference between the random variable's expected values above and below the median. An equal-interval, pure variance measure of ordinal dispersion is posited and compared to D. They correlate closely but not perfectly, and D has a serious problem when an extremal category has more than half the total cases. Both formulas are easily generalized to non-equal-interval scorings. A general linear model for categorical data permits easy statistical comparisons of D, but not the variance. D tends to underestimate the degree of significant dispersion in comparison to the variance formula, it is suggested.     

The Melanoma Patient Exchange: Insights from a Supportive Group Intervention for Melanoma Patients and their Caregivers

Melanoma is one of the fastest growing cancers worldwide, and the psychosocial impact of its diagnosis and treatment can be substantial. The authors implemented a support group for melanoma patients and caregivers to address a gap in support services. The authors describe insights from the first year of the program, including group format and dynamics, participant feedback, and satisfaction. Feedback was collected using the Group Session Rating Scale and two open-ended questions. Sixty-six members participated and responses demonstrated high satisfaction with the group (Mean = 38.7/40.0). Similar organizations may utilize these strategies to provide a support group option for their population of interest.     

Immigration,Bureaucracies and Policy Formulation: The Case of Quebec

Based on an ethnography of one illuminating case – the formulation of new immigration policy statement entitled “Together, we are Quebec” between 2014 and 2016 – this article argues that policy formulation is an important site of power and influence over immigration-related policies for bureaucrats. In dialogue with concepts and theories from public administration, it demonstrates that a broad mandate of reform and modernization, coupled with political tensions surrounding diversity, created opportunities for the bureaucracy to influence Quebec's immigration policy following its interests, relations, expertise and experience. In this case, the bureaucracy's influence operated through two pathways: problem definition and consensus building. While this influence is partially contingent on political and institutional characteristics of the Quebec context, this case shows that scholarship on immigration policy and politics should embrace a much broader reading of the influence of bureaucrats on the content and development of immigration-related policies.     

Comparative characteristics of estimators of the mean responding cell density in limiting dilution assays

The statistical problems associated with estimating the mean responding cell density in the limiting dilution assay (LDA) have largely been ignored. We evaluate techniques for analyzing LDA data from multiple biological samples, assumed to follow either a normal or gamma distribution. Simulated data is used to evaluate the performance of an unweighted mean, a log transform, and a weighted mean procedure described by Taswell (1987). In general, an unweighted mean with jackknife estimates will produce satisfactory results. In some cases, a log transform is more appropriate. Taswell's weighted mean algorithm is unable to estimate an accurate variance. We also show that methods which pool samples, or LDA data, are invalid. In addition, we show that optimization of the variance in multiple sample LDA's is dependent on the estimator, the between-organism variance, the replicate well size, and the numberof biological samples. However, this optimization is generally achieved by maximizing biological samples at the expense of well replicates.
