Distribution of Exposure Concentrations and Doses for Constituents of Environmental Tobacco Smoke

The ultimate goal of the research reported in this series of three articles is to derive distributions of doses of selected environmental tobacco smoke (ETS)-related chemicals for nonsmoking workers. This analysis uses data from the 16-City Study collected with personal monitors over the course of one workday in workplaces where smoking occurred. In this article, we describe distributions of ETS chemical concentrations and the characteristics of those distributions (e.g., whether the distribution was log normal for a given constituent) for the workplace exposure. Next, we present population parameters relevant for estimating dose distributions and the methods used for estimating those dose distributions. Finally, we derive distributions of doses of selected ETS-related constituents obtained in the workplace for people in smoking work environments. Estimating dose distributions provided information beyond the usual point estimate of dose and showed that the preponderance of individuals exposed to ETS in the workplace were exposed at the low end of the dose distribution curve. The results of this analysis include estimations of hourly maxima and time-weighted average (TWA) doses of nicotine from workplace exposures to ETS (extrapolated from 1 day to 1 week) and doses derived from modeled lung burdens of ultraviolet-absorbing particulate matter (UVPM) and solanesol resulting from workplace exposures to ETS (extrapolated from 1 day to 1 year).     

Affordance of Participation Rights for Children in Home‐based Education and Care: An Interactive Process Model of Participation — 2007

Recent models relating to the affordance of children’s participation rights, based on articles 12 and 13 of the United Nations Convention on the Rights Of the Child (1989) , have focused on the role of and strategies used by the adults working with children (Children and Society 10 , 2001: 107–117; Children and Society 20 , 2006: 209–222). Whilst these adults play a pivotal role in affording participation rights, children, and their parents/family/whānau, play an equally important role. This paper explores the complex interplay of roles, relationships, and strategies used by adults and children in home‐based education settings in Aotearoa/New Zealand, that support the affordance of participation rights for children. It identifies key aspects of practice that underpin this, and presents an alternative model of participation that is in keeping with a sociocultural approach to children’s learning and development, and acknowledges them, in the right conditions, as having a voice and agency as citizens in their own right.     

The Status of Nutrition Education in ACHA College and University Health Centers

Abstract

An assessment of the prevalence and scope of nutrition services offered through 208 randomly selected American College Health Association member student health centers revealed that 79% of the 160 respondents provided some type of nutrition education for students. One-to-one counseling, available at 96% of the institutions, was the most common approach. The larger the school's enrollment, the more likely it was to provide programs in nutrition. All of the institutions with student populations of more than 35,000 offered some type of nutrition service, as did 52% of the 19 schools with enrollments between 2,000 and 5,000. Health educators, nurses, doctors, dietitians, and trained peer educators provided the services, with registered dietitians the most common providers and often coordinators of the programs. Costs to students for nutrition interventions were nominal; weightmanagement programs were the most expensive and showed the greatest variation in content.     

Developing a Vision for the Common Core Classroom: What Does Elementary Social Studies Look Like?

In each edition of their book Doing History: Investigating with Children in Elementary and Middle Schools, Levstik and Barton (2011) encourage us to take a mental journey to imagine classrooms where students regularly “do history” (xi). The social studies experiences that many educators envision for elementary classrooms include teaching students to frame questions, read for information, and organize primary and secondary sources to share their knowledge with classmates. NCSS provides an infrastructure for social studies goals in which knowledge, skills and attitudes are developed in meaningful social studies lessons. When viewed through the lens of the Common Core State Standards for English Language Arts & Literacy in History/Social Studies, Science, and Technical Subjects (CCSS ELA), we recognize the fundamental nature of aligning social studies standards with literacy strategies for elementary teaching and learning. The purpose of this article is to examine the usefulness of CCSS ELA for teaching elementary social studies. The authors share a vision for the “common core classroom” that includes a range of literacy strategies for teaching standards-based social studies.     

The golden star: an emotional repertoire of scientific discovery and legacy

This paper examines vocabularies of emotion in the discovery narratives of a group of genetic scientists. The discovery of the gene for myotonic dystrophy in 1992 was part of a unique and highly competitive phase of molecular genetic research into single gene hereditary conditions. Members of a small group of scientists who made a significant contribution to the discovery of the gene were interviewed sixteen years later about the impact of that discovery. They structured their memories into narrative accounts characterized by vivid recall, colourful language and use of an emotional repertoire to reconstruct the dynamics, relationships and personal meaning of the discovery. The focus of this emotional language was on what it meant to be a molecular scientist, the dynamics of the incremental work that led to eventual success, the networks surrounding the team and the legacy of discovery in relation to science and to the individual scientists. The emotional repertoire revealed subtle differences between accounts, where there was universal recognition of the importance of the discovery for a scientific career but ambivalence regarding its personal meaning for some key actors.     

Caregiving for Parents and In-Laws: Commonalities and Differences

This study examined support, stress, and well-being between adults who provide care for an aging and disabled parent and those who care for an aging and disabled parent-in-law. The study utilized a sample of individuals caring for a parent (n?=?77), individuals caring for an in-law (n?=?26) and a comparison group of noncaregivers (n?=?1,939) from the Midlife Development in the United States study. In-law caregivers provided more financial assistance but adult child caregivers provided more emotional support and unpaid work. Adult child caregivers reported poorer mental health and family strain; in-law caregivers reported more spouse support and less family strain.     

Introduction: Accountability in Neuroethics

Pharmaceutical sponsored clinical trials, formerly conducted predominantly in the United States and Europe, have expanded to emerging regions, including the Middle East. Our study explores factors influencing clinical trial privacy and confidentiality in the United Arab Emirates. Factors including concept familiarity, informed consent compliance, data access, and preservation, were analyzed to assess current practices in the Arab world. As the UAE is an emerging region for clinical trials, there is a growing need for regulations related to data confidentiality and subject privacy. Informational and decisional privacy should be viewed within the realms of Arab culture and religious background.     

“They're not my favourite people”: What mothers who have experienced intimate partner violence say about involvement in the child protection system

Although the primary aim of child protection services (CPS) is to ensure the well-being and safety of children, policy decision-makers and service providers are increasingly concerned about the potential harm children encounter when they witness the abuse of their caregivers. Researchers who have conducted reviews of child protection files in both Canada and the United States report that few cases in which intimate partner violence (IPV) is substantiated are referred for additional services. In this article, we question whether this response is appropriate. Through examining the results of a qualitative study with sixty-four women who experienced IPV and were thus involved in the child protection system, we have been able to analyze the impact of CPS practices on those women who received services and those who did not. Our findings suggest that CPS can be an important resource for women who experience IPV, but changes to current practices are necessary to ensure that services offered are beneficial.
