Gender discourses in academic mobility

Despite increasing geographic mobility among academic staff, gendered patterns of involvement in academic mobility have largely escaped scrutiny. Positioned within literatures on internationalization, physical proximity, gender and parenthood in academic mobility and understandings of gender as a process enacted through both discursive and embodied practices, we use discourse analysis based on interviews with academics in New Zealand to examine differences in language that create differing realities with regards to gender and obligations of care in academic mobility decisions. The findings reveal how academic mobility is discursively formulated as ‘essential’ to successful academic careers, with the need for frequent travel justified despite advances in virtual communication technologies. Heteronormative discourses are shown to disrupt and fragment the opportunities female academics have to engage in academic mobility. However, we also uncover ways in which these discourses are resisted, wherein fathers articulate emotional strain associated with academic mobility. The article shows how discourse works to constitute the essentialization of academic mobility, and the uneven gendered practices associated with it, whilst also giving voice to gender inequities in academic mobility from the southern hemisphere.     

Rule learning transfer across linguistic and visual modalities in 7-month-old infants

Rule learning (RL) refers to infants’ ability to extract high-order, repetition-based rules from a sequence of elements and to generalize them to new items. RL has been demonstrated in both the auditory and the visual modality, but no studies have investigated infants’ transfer of learning across these two modalities, a process that is fundamental for the development of many complex cognitive skills. Using a visual habituation procedure within a cross-modal RL task, we tested 7-month-old infants’ transfer of learning both from speech to vision (auditory-visual—AV—condition) and from vision to speech (visual-auditory—VA—condition). Results showed a transfer of learning in the AV condition, but only for those infants who were able to efficiently extract the rule during the learning (habituation) phase. In contrast, in the VA condition infants provided no evidence of RL. Overall, this study indicates that 7-month-old infants can transfers high-order rules across modalities with an advantage for transferring from speech to vision, and that this ability is constrained by infants’ individual differences in the way they process the to-be-learned rules.     

Parenting and Children's Distress Reactivity during Toddlerhood: An Examination of Direction of Effects

During early childhood, harsh and emotionally negative parent–child exchanges are expected to increase children's risk for developing later conduct problems. The present study examined longitudinal associations between the quality of parenting responses and children's distress reactivity during children's second year of life. Forty-seven mother–child dyads completed observational assessments of children's distress reactivity and mothers' harsh and supportive parenting when children were 12 and 24 months of age. Results indicated that mothers' contingent harsh parenting responses to children's non-compliance when children were 12 months of age predicted increases in children's observed distress from 12 to 24 months, but children's level of distress at 12 months did not predict change in harsh parenting responses over the same time period. In contrast, supportive parenting contingent responses did not predict declines in children's distress reactivity, although children's distress reactivity predicted declines in mothers' supportive parenting responses from 12 to 24 months. Results are discussed in terms of the implications of the quality of parent–child interactions as a point of entry onto developmental pathways of risk.     

What Affects the Quality of Economic Analysis for Life‐Saving Investments?‡

Economic analysis of life-saving investments in both the public and private sectors has the potential to dramatically improve longevity and the quality of life, but only if the analyses on which decisions are based are done well. In this article, we analyze a data set that provides information on the content and quality of journal articles that measure the cost-effectiveness of life-saving investments. Our study is the first to provide a detailed multivariate analysis of factors affecting objective measures of quality. We also explore whether a series of recommendations by an expert panel convened by the U.S. Public Health Service affect the way analyses of specific life-saving investments are done. Our results suggest that four factors are positively correlated with an index we construct to measure analytical quality: (1) having at least one author affiliated with a university, (2) publication in a journal that has experience in publishing these analyses, (3) if the life-saving investment is located in the United States, and (4) if the analysis considers a measure of social costs or benefits. Somewhat surprisingly, a study's funding source and whether it is affiliated with industry are not significantly correlated with the quality index. Finally, neither time nor the panel guidelines had an impact on the index.     

Institutionalization,Romanian Adoptions and Executive Functioning

The impact of a traumatic environment during early childhood is linked to short-term and long-term difficulties in adoptees. This study, utilizing a non-random, cross-sectional analysis of 123 children adopted from Romania, focused on executive cognitive functioning. One-third of the sample had not been institutionalized while the other two-thirds had been institutionalized for varying lengths of time from 1 month to more than 3 years, resulting in a “natural experiment” that allowed us to compare these two groups. Information from parents and teachers was obtained regarding their perception of the child’s executive functioning. Results indicate that, after many years in their adoptive families, 40% of the adoptees had physical challenges and 36% were in at least some special education classes. The best predictor of parental perception of current executive functioning was parent perception of the current parent–child relationship and not preadoptive history.     

Romanian Adoptees and Pre-adoptive Care: A Strengths Perspective

Ninety-one parents of 120 adopted Romanian children who were part of a longitudinal study were surveyed to determine perceptions of their relationships with their children, their adoption experiences, and the children’s strengths. The Behavioral and Emotional Rating Scale (BERS) was used and parents were easily able to rate their children’s emotional and behavioral strengths. Levels of parent–child relationship satisfaction were the most consistent predictors of child emotional and behavioral strength. The child’s age at the time of the survey was a significant predictor of strengths, indicating overall that younger children had more perceived strengths. Parents identified fewer strengths among children with longer histories of institutional care. The importance of a strong parent–child relationship and resilience after a history of early institutional care are discussed.     

How Kids Learn to Say the Darnedest Things: The Effect of Multiple Exemplar Instruction on the Emergence of Novel Verb Usage

We report experiments using time-lagged pre- and postintervention designs with (a) 4 first graders with learning delays, and (b) a systematic replication with 3 preschoolers with learning delays. Both experiments tested the effects of multiple exemplar instructional procedures (MEI) on the emergence of untaught past tense emission of novel regular verbs (e.g., jumped derived from jump) and grammatically inaccurate but experimentally correct usage of irregular verbs (e.g., singed derived from sing). Prior to the MEI, none of the children could produce regular or irregular past tense forms to pictures that provided simulated contexts (pictures with backgrounds for past and present tense). MEI provided across the picture contexts for past and present tense used separate training sets of verbs to teach children to form regular past tense. After either 1 or 2 MEI training sets, the children emitted accurate past tense forms of the untaught regular and inaccurate, but experimentally correct irregular verbs. These findings provided an instructional history that resulted in the children''s acquisition of past tense for untaught regular past tense verbs and “creative” errors with irregular tenses. Results are discussed in terms of the research on experimentally induced sources for novel verbal behavior and related interpretations.     

Economic Pressure, Maternal Depression, and Child Adjustment in Latino Families: An Exploratory Study

The goal of this study was to investigate the impact of poverty and economic pressure upon the adjustment of mothers and children in immigrant Latino families. Participants included 56 first generation Latina mothers who completed questionnaires addressing economic difficulties, depression, social support, and behavior problems exhibited by their children (30 boys, 26 girls) who ranged in ages from 4 to 13. Results indicate that maternal depression mediates the relationship between maternal economic pressure and child adjustment. Social support was found to further moderate the relationship between maternal depression and child internalizing problems. Gender differences indicated that relations were stronger among mothers of boys than mothers of girls.     

A Dynamic Model to Assess Microbial Health Risks Associated with Beneficial Uses of Biosolids

There is increasing interest in the development of a microbial risk assessment methodology for regulatory and operational decision making. This document presents a methodology for assessing risks to human health from pathogen exposure using a population-based model that explicitly accounts for properties unique to an infectious disease process, specifically secondary transmission and immunity. To demonstrate the applicability of this risk-based method, numerical simulations were carried out for a case study example in which the route of exposure was direct consumption of biosolids-amended soil and the pathogen present in the soil was enterovirus. The output from the case study yielded a decision tree that differentiates between conditions in which the relative risk from biosolids exposure is high and those conditions in which the relative risk from biosolids is low. This decision tree illustrates the interaction among the important factors in quantifying risk. For the case study example, these factors include biosolids treatment processes, the pathogen shedding rate of infectious individuals, secondary transmission, and immunity. Further refinement in methods for determining biosolids exposures under field conditions would certainly increase the utility of these approaches.
