Abstract

Recent social policy discourses in Aotearoa New Zealand focus on vulnerable children’s well-being and the detrimental, long-term and costly impacts of child poverty. The discourse pervading much of the policy labels children and young people as ‘vulnerable’ or ‘at risk’ or ‘in crisis’, a view, which we argue, is both disempowering and marginalising. We propose a shift in focus which views children and young people as agentic, capable and competent. Drawing on several small-scale research projects and reports we demonstrate how, when asked, children and young people can participate effectively in discussions about policy matters that concern them (Article 12, United Nations Convention on the Rights of the Child, 1989 [UNCROC]). We have much to learn from the insights children share with us when asked, but very often existing structures, at both government and community level, do not include adequate processes to hear their voices, let alone act on what has been communicated.  相似文献   

Dielectrophoretic microfluidic device for the continuous sorting of Escherichia coli from blood cells     

Kuczenski RS  Chang HC  Revzin A 《Biomicrofluidics》2011,5(3):32005-3200515

Microfluidic diagnostic devices promise faster disease identification by purifying and concentrating low-abundance analytes from a flowing sample. The diagnosis of sepsis, a whole body inflammatory response often caused by microbial infections of the blood, is a model system for pursuing the advantages of microfluidic devices over traditional diagnostic protocols. Traditional sepsis diagnoses require large blood samples and several days to culture and identify the low concentration microbial agent. During these long delays while culturing, the physician has little or no actionable information to treat this acute illness. We designed a microfluidic chip using dielectrophoresis to sort and concentrate the target microbe from a flowing blood sample. This design was optimized using the applicable electrokinetic and hydrodynamic theories. We quantify the sorting efficiency of this device using growth-based assays which show 30% of injected microbes are recovered viable, consistent with the electroporation of target cells by the dielectrophoretic cell sorters. Finally, the results illustrate the device is capable of a five-fold larger microbe concentration in the target analyte stream compared to the waste stream at a continuous sample flow rate of 35 μl∕h.  相似文献   

Racist Violations and Racializing Apologia in a Post-Racism Era     

Michelle A. Holling  Dreama G. Moon  Alexandra Jackson Nevis 《Journal of International and Intercultural Communication》2014,7(4):260-286

In theorizing the dialectic of public acts of white racial offenses and the in/sufficiency of apologia associated with white racial discourse, we examine racist violations and racializing apologia from 24 white public figures in the United States between 1996 and 2012. Analysis of racist violations reveals that each offense undermines race as a social and political marker, whereas racializing apologia makes explicit the constant force of racialization and latent nature of whiteness in apologia strategies. We view racializing apologia as potentially liberatory, capable of allowing for a defense of oneself and challenging reproduction of racial formations.  相似文献   

Fostering uncertainty tolerance in anatomy education: Lessons learned from how humanities,arts and social science (HASS) educators develop learners' uncertainty tolerance     

Michelle D. Lazarus  Amany Gouda-Vossos  Angela Ziebell  Gabrielle Brand 《Anatomical sciences education》2023,16(1):128-147

Uncertainty tolerance, individuals' perceptions/responses to uncertain stimuli, is increasingly recognized as critical to effective healthcare practice. While the Covid-19 pandemic generated collective uncertainty, healthcare-related uncertainty is omnipresent. Correspondingly, there is increasing focus on uncertainty tolerance as a health professional graduate “competency,” and a concomitant interest in identifying pedagogy fostering learners' uncertainty tolerance. Despite these calls, practical guidelines for educators are lacking. There is some initial evidence that anatomy education can foster medical students' uncertainty tolerance (e.g., anatomical variation and dissection novelty), however, there remains a knowledge gap regarding robust curriculum-wide uncertainty tolerance teaching strategies. Drawing upon humanities, arts and social sciences (HASS) educators' established uncertainty tolerance pedagogies, this study sought to learn from HASS academics' experiences with, and teaching practices related to, uncertainty pedagogy using a qualitative, exploratory study design. Framework analysis was undertaken using an abductive approach, wherein researchers oscillate between inductive and deductive coding (comparing to the uncertainty tolerance conceptual model). During this analysis, the authors analyzed ~386 min of data from purposively sampled HASS academics' (n = 14) discussions to address the following research questions: (1) What teaching practices do HASS academics' perceive as impacting learners' uncertainty tolerance, and (2) How do HASS academics execute these teaching practices? The results extend current understanding of the moderating effects of education on uncertainty tolerance and supports prior findings that the anatomy learning environment is ripe for supporting learner uncertainty tolerance development. This study adds to growing literature on the powerful moderating effect education has on uncertainty tolerance and proposes translation of HASS uncertainty tolerance teaching practices to enhance anatomy education.  相似文献   

Frontal asymmetry assessed in infancy using functional near-infrared spectroscopy is associated with emotional and behavioral problems in early childhood     

Caroline M. Kelsey  Margaret A. Modico  John E. Richards  Michelle Bosquet Enlow  Charles A. Nelson 《Child development》2023,94(2):563-578

Frontal asymmetry (FA), the difference in brain activity between the left versus right frontal areas, is thought to reflect approach versus avoidance motivation. This study (2012–2021) used functional near-infrared spectroscopy to investigate if infant (M_age = 7.63 months; N = 90; n = 48 male; n = 75 White) FA in the dorsolateral prefrontal cortex relates to psychopathology in later childhood (M_age = 62.05 months). Greater right FA to happy faces was associated with increased internalizing (η² = .09) and externalizing (η² = .06) problems at age 5 years. Greater right FA to both happy and fearful faces was associated with an increased likelihood of a lifetime anxiety diagnosis (R² > .13). FA may be an informative and early-emerging marker for psychopathology.  相似文献

Reconfigurable microfluidics combined with antibody microarrays for enhanced detection of T-cell secreted cytokines     

Arnold Chen  Tam Vu  Gulnaz Stybayeva  Tingrui Pan  Alexander Revzin 《Biomicrofluidics》2013,7(2)

Cytokines are small proteins secreted by leukocytes in blood in response to infections, thus offering valuable diagnostic information. Given that the same cytokines may be produced by different leukocyte subsets in blood, it is beneficial to connect production of cytokines to specific cell types. In this paper, we describe integration of antibody (Ab) microarrays into a microfluidic device to enable enhanced cytokine detection. The Ab arrays contain spots specific to cell-surface antigens as well as anti-cytokine detection spots. Infusion of blood into a microfluidic device results in the capture of specific leukocytes (CD4 T-cells) and is followed by detection of secreted cytokines on the neighboring Ab spots using sandwich immunoassay. The enhancement of cytokine signal comes from leveraging the concept of reconfigurable microfluidics. A three layer polydimethylsiloxane microfluidic device is fabricated so as to contain six microchambers (1 mm × 1 mm × 30 μm) in the ceiling of the device. Once the T-cell capture is complete, the device is reconfigured by withdrawing liquid from the channel, causing the chambers to collapse onto Ab arrays and enclose cell/anti-cytokine spots within a 30 nl volume. In a set of proof-of-concept experiments, we demonstrate that ∼90% pure CD4 T-cells can be captured inside the device and that signals for three important T-cell secreted cytokines, tissue necrosis factor-alpha, interferon-gamma, and interleukin-2, may be enhanced by 2 to 3 folds through the use of reconfigurable microfluidics.  相似文献   

The effect of recovery duration on running speed and stroke quality during intermittent training drills in elite tennis players     

Alexander Ferrauti  Babette M. Pluim  Karl Weber 《Journal of sports sciences》2013,31(4):235-242

The aim of this study was to assess the effect of the recovery duration in intermittent training drills on metabolism and coordination in sport games. Ten nationally ranked male tennis players (age 25.3±3.7 years, height 1.83±0.8 m, body mass 77.8±7.7 kg; mean ±s _x ) participated in a passing-shot drill (baseline sprint with subsequent passing shot) that aimed to improve both starting speed and stroke quality (speed and precision). Time pressure for stroke preparation was individually adjusted by a ball-machine and corresponded to 80% of maximum running speed. In two trials (T₁₀, T₁₅) separated by 2 weeks, the players completed 30 strokes and sprints subdivided into 6 2 5 repetitions with a 1 min rest between series. The rest between each stroke-and-sprint lasted either 10 s (T₁₀) or 15 s (T₁₅). The sequence of both conditions was randomized between participants. Post-exercise blood lactate concentration was significantly elevated in T₁₀ (9.04±3.06 vs 5.01±1.35 mmol·l^-1, P ? 0.01). Running time for stroke preparation (1.405±0.044 vs 1.376±0.045 s, P ? 0.05) and stroke speed (106±12 vs 114±8 km·h^-1, P ? 0.05) were significantly decreased in T₁₀, while stroke precision - that is, more target hits ( P ? 0.1) and fewer errors (P ? 0.05) - tended to be higher. We conclude that running speed and stroke quality during intermittent tennis drills are highly dependent on the duration of recovery time. Optimization of training efficacy in sport games (e.g. combined improvement of conditional and technical skills) requires skilful fine-tuning of monitoring guidelines.  相似文献
