The effect of breast support and breast pain on upper-extremity kinematics during running: implications for females with large breasts

The relationship between inappropriate breast support and upper-extremity kinematics for female runners is unclear. The purpose of this study was to investigate the effect of breast support and breast pain on upper-extremity kinematics during running. Eleven female recreational runners with larger breasts (UK D and E cup) completed a 7 min 20 s treadmill run (2.58 m · s^?1) in a high and low breast support condition. Multi-planar breast and upper-extremity kinematic data were captured in each breast support condition by eight infrared cameras for 30 s towards the end of the run. Breast pain was rated at the end of each treadmill run using a numeric analogue scale. The high support bra reduced breast kinematics and decreased breast pain (P < 0.05). Upper-extremity kinematics did not differ between breast support conditions (P > 0.05), although some moderate positive correlations were found between thorax range of motion and breast kinematics (r = 0.54 to 0.73). Thorax and arm kinematics do not appear to be influenced by breast support level in female runners with large breasts. A high support bra that offers good multi-planar breast support is recommended for female runners with larger breasts to reduce breast pain.     

Pivoting: leveraging opportunities in a turbulent health care environment

Purpose:

The purpose of this lecture is to challenge librarians in clinical settings to leverage the opportunities presented by the current health care environment and to develop collaborative relationships with health care practitioners to provide relevant services.

Discussion:

Health care organizations are under financial and regulatory pressures, and many hospital librarians have been downsized or have had their positions eliminated. The lecture briefly reviews hospital librarians'' roles in the past but focuses primarily on our current challenges. This environment requires librarians to be opportunity focused and pivot to a new vision that directs their actions. Many librarians are already doing this, and colleagues are encouraging us to embrace these opportunities. Evidence from publications, websites, discussion lists, personal communications, and the author''s experience is explored.

Conclusion:

Developing interdisciplinary and collaborative relationships in our institutions and providing relevant services will mark our progress as vital, contributing members of our health care organizations.     

Big Math for Little Kids: The Effectiveness of a Preschool and Kindergarten Mathematics Curriculum

Research Findings: Big Math for Little Kids (BMLK) is a mathematics curriculum developed for use with 4- and 5-year-old children. To investigate the BMLK curriculum's effect on children's mathematics knowledge, this cluster-randomized controlled trial randomly assigned child care centers to provide mathematics instruction to children, using either the BMLK mathematics curriculum or the centers’ business-as-usual curriculum, over a 2-year period when children were in prekindergarten and kindergarten. Participants in the study were 762 children and their teachers at 16 publicly subsidized child care centers. The study assessed children's mathematics knowledge using the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B), Direct Mathematics Assessment, a measure of young children's mathematics knowledge that is not aligned with the curriculum. The ECLS-B scores of children in the BMLK group increased significantly more than did those of children in the comparison group. The study also included exploratory analyses to examine whether children in the BMLK group demonstrated evidence of improved mathematical language. Practice or Policy: These results indicate that the BMLK curriculum, which is designed to help teachers use play-based, developmentally appropriate mathematics instruction, has a positive impact on young children's mathematics knowledge as measured by a general mathematics assessment that is not aligned with the curriculum.     

Preschoolers rely on rich speech representations to process variable speech

To learn language, children must map variable input to categories such as phones and words. How do children process variation and distinguish between variable pronunciations (“shoup” for soup) versus new words? The unique sensory experience of children with cochlear implants, who learn speech through their device's degraded signal, lends new insight into this question. In a mispronunciation sensitivity eyetracking task, children with implants (N = 33), and typical hearing (N = 24; 36–66 months; 36F, 19M; all non-Hispanic white), with larger vocabularies processed known words faster. But children with implants were less sensitive to mispronunciations than typical hearing controls. Thus, children of all hearing experiences use lexical knowledge to process familiar words but require detailed speech representations to process variable speech in real time.

Responding to racism at school: Ethnic-racial socialization and the academic engagement of Black and Latinx youth

Guided by the Theory of Racial Socialization in Action (TRSA; Smith-Bynum in press), this study examined observed caregiver-provided ethnic-racial socialization in response to a school-based discriminatory dilemma. Forty-five Black and 36 Latinx caregivers (88% mothers) with low-income and their children (M_age = 11.09, SD = 0.29; 46.3% female) participated in Dallas, Texas from 2018 to 2019. Dyads responded to a hypothetical scenario in which a school counselor makes a discriminatory comment to the child. Results of a factor mixture analysis suggested that caregivers engaged in the dialogue using one of four approaches: Low-engaged, Legacy, Racial Literacy, or High-engaged. Profiles were found to differ significantly by the race/ethnicity and language of caregivers and were associated with youth’s concurrent behavioral engagement (R² = .04).     

On being critical: uniting theory and practice through emancipatory action research

This paper engages with some of the specific issues that challenge critical practice. My argument is related to the Carr and Kemmis debate on ‘staying critical’ and to ideas expressed in my current book, Community Development: A Critical Approach. I refer to critical practice as any practice that has a transformative social justice intention, and which happens in a range of contexts from grassroots community activism to more institutionalised settings, such as hospitals or schools. My own professional base is community development, and this paper is founded on emancipatory action research developed over many years in grassroots practice. It is my view that emancipatory action research, committed to the practice of social justice, with the intention of bringing about social change, is a necessary component of critical practice. In fact, I would go so far as to say that emancipatory action research is the glue that binds critical praxis in a unity of theory and action. However, all too often collective action for change is not followed through to its greatest potential, and practice remains contextualised in the immediate, local and specific without making critical connections with the structural roots of oppression from which inequalities emanate. The result is that we constantly fixate on symptoms, and leave the root causes free to perpetuate oppressions. At the same time, we find ourselves in a globalised world marked by intensifying social divisions. So, it is my intention to raise a few issues which present challenges to get beyond sticking points in critical practice as we face times in which there is an accelerating urgency to ‘become critical’.     

The relation between abuse and violent delinquency: the conversion of shame to blame in juvenile offenders

Objective

While the relationship between abusive parenting and violent delinquency has been well established, the cognitive and emotional processes by which this occurs remain relatively unidentified. The objective of this work is to apply a conceptual model linking abusive parenting to the conversion of shame into blaming others and therefore to violent delinquency.

Methods

A retrospective study of 112 adolescents (90 male; 22 female; ages 12-19 years; M = 15.6; SD = 1.4) who were incarcerated in a juvenile detention facility pending criminal charges, completed measures of exposure to abusive and nonabusive discipline, expressed and converted shame, and violent delinquency.

Results

Findings tend to confirm the conceptual model. Subjects who converted shame (i.e., low expressed shame, high blaming others) tended to have more exposure to abusive parenting and showed more violent delinquent behavior than their peers who showed expressed shame. Subjects who showed expressed shame (i.e., high expressed shame, low blaming others) showed less violent delinquency than those who showed converted shame.

Conclusions

Abusive parenting impacts delinquency directly and indirectly through the effects of shame that is converted. Abusive parenting leads to the conversion of shame to blaming others, which in turn leads to violent delinquent behavior.

Practice implications

For juvenile offenders, the conversion of shame into blaming others appears to contribute to pathological outcomes in relation to trauma. Translation of this work into clinical practice is recommended.
