Push or Carry? Pragmatic Opportunities for Language Development in Strollers versus Backpacks

Strollers and backpacks are employed early, frequently, and throughout the first year, with parents overwhelmingly using strollers. However, because these transport modalities put infants in different proximities to caregivers, postures, and states of alertness, their use may translate to different opportunities that are of developmental consequence, particularly with regard to language. We used GoPro technology in a within‐subjects counterbalanced design to measure dyadic vocalizations in strollers and backpacks with 7‐ to 11‐month‐old infants. Parent‐infant dyads (N = 36) who regularly used both transport modes took two 8‐min walks in their own neighborhoods using their own carriers while wearing lightweight head‐mounted GoPros. There was significantly more parent speech, infant vocalizations, dyadic conversations, and infant‐initiated speech in backpacks, as well as more head motion consistent with visual scanning by infants. Backpacks appear to be a practical way to encourage more engaging, language‐enriched developmental opportunities in the critical first year.     

Hurricane Isaac: A Longitudinal Analysis of Storm Characteristics and Power Outage Risk

In August 2012, Hurricane Isaac, a Category 1 hurricane at landfall, caused extensive power outages in Louisiana. The storm brought high winds, storm surge, and flooding to Louisiana, and power outages were widespread and prolonged. Hourly power outage data for the state of Louisiana were collected during the storm and analyzed. This analysis included correlation of hourly power outage figures by zip code with storm conditions including wind, rainfall, and storm surge using a nonparametric ensemble data mining approach. Results were analyzed to understand how correlation of power outages with storm conditions differed geographically within the state. This analysis provided insight on how rainfall and storm surge, along with wind, contribute to power outages in hurricanes. By conducting a longitudinal study of outages at the zip code level, we were able to gain insight into the causal drivers of power outages during hurricanes. Our analysis showed that the statistical importance of storm characteristic covariates to power outages varies geographically. For Hurricane Isaac, wind speed, precipitation, and previous outages generally had high importance, whereas storm surge had lower importance, even in zip codes that experienced significant surge. The results of this analysis can inform the development of power outage forecasting models, which often focus strictly on wind‐related covariates. Our study of Hurricane Isaac indicates that inclusion of other covariates, particularly precipitation, may improve model accuracy and robustness across a range of storm conditions and geography.     

TOWARD A SUSTAINABLE US HEALTH POLICY: LOCAL CONGRUITIES AND GLOBAL INCONGRUITIES

The United States health care system is congruous with the US economy and with prevailing local values: it is resource intensive, technology-focused, consumer-oriented, individualistic, and unequally available. However, the US health system is incongruous not only with other health care systems around the world, but also with the increasingly global nature of health care concerns. Indeed the US system, according to the World Bank, stands out as strikingly expensive and ineffective in its public health impact. The article first identifies several significant incongruities, and then argues that there is an increasing obligation for the US health system to become more ethically responsive in light of global concerns. Sustainable health should be sought as a significant goal of US health services. Health services need to be fully and accurately assessed for their environmental costs, which need to be made explicit. Actual, universal access to basic health care services needs to take priority over scarce high-tech therapies when resource allocations are made. Traditional health values such as individualism, autonomy and privacy must be placed within a context of global interdependence and responsibilities to community. Public health fundamentals such as adequate nutrition, clear water, and a biologically intact ecosystem must be emphasized. Innovations in health technology need to be made with attention to their potential international use and impact. Finally, a longer time horizon for planning is needed, taking into account environmentally caused health problems arising fifty years or more in the future.     

Negotiating multiple identities in a queer Vietnamese support group

My participant-observation with O-M?i, a support group for Vietnamese lesbians, bisexual women and female-to-male transgenders, and interviews with members, focusing on how different identity issues are negotiated, suggest that despite O-M?i's claim of supporting its members' multiple marginalized identities, group processes in everyday pragmatic interactions construct a hierarchy that centers and normalizes experiences of bilingual Vietnamese lesbians. This renders the marginalization of bisexual women, transgender men, and Vietnamese/English monolingual members. Using the concept of "identity work" to examine the intersection of race/ethnicity, class, and gender/sexuality as everyday (counter)hegemonic processes, I discuss how organizational structure, discourse resources, and personal politics orient and mold members' talk and interactions leading to normalization and/or marginalization of certain groups' experiences.     

Anticipating attendance in reminiscence therapy with measures of mood and happiness

Nineteen community volunteers for a reminiscence intervention were grouped into those attending no more than one-quarter of sessions and those attending approximately three-quarters of sessions. A model of psychological well-being was used to discriminate these groups. Predictions from the model were confirmed in two analyses: attendance was related negatively to baseline mood but positively to baseline happiness; the acute/chronic environmental discrepancy term of the model was negatively related to attendance. The model correctly assigned 16/19 (85%) of subjects to attendance categories.     

Preparing Social Work Students for Rural Child Welfare Practice: Emerging Curriculum Competencies

Multiple issues that are unique to child welfare social work practice in rural areas markedly affect workforce recruitment and retention, yet little attention is given to the proficiencies needed to equip emerging social workers for this growing area of the field. Curriculum content is needed that provides students with the opportunity to master the skills needed to thrive as child welfare social workers in rural areas. Using an evidence-based practice critical thinking model as a guide, a systematic review of literature and documents addresses many of the competencies needed to prepare social work students for child welfare practice in rural areas. These competencies are identified. Suggestions for integration into the social work curriculum are offered.     

Stimulus-Stimulus Pairing and Subsequent Mand Acquisition of Children with Various Levels of Verbal Repertoires

Effects of a stimulus-stimulus pairing procedure on the subsequent acquisition of mand operants were investigated. An attempt was made to shape novel sounds that emerged through the pairing procedure into a mand. Six children, aged two to five years, with moderate to severe language and communication delays, participated. Two conditions were used following the pairing condition: postpairing and direct reinforcement. The emergence of mands was compared across these conditions. An additional analysis was made of the relation between participants'' baseline verbal repertoires and the effects of the pairing and the emergence of mands. Results indicate the possibility of stimulus control from a stimulus-stimulus pairing to mand as shown in two of the participants who had demonstrated high rates of vocal play and low to no verbal repertoire prior to this study. Target vocal sounds during postpairing and direct reinforcement condition remained at zero to low levels for participants with high verbal repertoire and little vocal play, warranting future studies on relations between the pre-existing verbal repertoire and the effectiveness of stimulus-stimulus pairing.     

Moving toward cultural competence in the child welfare system

This paper uses a culturally competent (Cross, Bazron, Dennis & Isaacs, 1989) perspective to examine the child welfare system's, namely protective services, response to children of color. The purpose of the paper is to indicate how the absence of cross-cultural considerations in both child welfare policy and practice, limits the effectiveness of service delivery to children of color and their families. Specifically, three key aspects of the child welfare system are addressed: past responses to children of color, worker-client interactions, and child protective service agencies. The paper ends with several recommendations.     

The integration of support for HIV and AIDS and livelihood security: district level institutional analysis in southern Africa

Livelihood insecurity, HIV and AIDS, and environmental change, including high climate variability, have negatively impacted the southern African region for the last decade. It is increasingly evident that there is a complex interplay of factors shaping rural livelihoods at various scales. Recognition of the varied impacts of HIV and AIDS has led to development of a conceptual framework that utilises the ‘AIDS Timeline’ or ‘Programming Matrix’, which enables differential intervention strategies to be adopted depending on the dominant impacts and trends on livelihoods. This paper presents this approach and links it to case study material from two districts in Malawi and South Africa. The evidence suggests that although there are some areas where HIV and AIDS are mainstreamed into livelihood security interventions, this is not sufficient, as holistic environmental and social approaches are not adopted. This paper reflects on the fieldwork findings to link to the AIDS Timeline in support of appropriate interventions. At the same time, we highlight the urgency in addressing the meso-scale and adopting a holistic framework that addresses livelihood security from a range of angles, including the implications for the chronically ill, interactions with environment and the capacity to implement change.
