RESUMEN

Given the value placed on honesty and the negative consequences of lying, encouraging children's truth-telling is important. The present investigation assessed honesty promotion techniques for encouraging 3-8-year-old Canadian children's (Study 1: n = 301, 54% female; Study 2: n = 229, 50% female from predominantly White middle-class samples) disclosure of a transgression and whether they varied by age. Study 1 examined promising to tell the truth, inducing self-awareness, and the combination of both promising and self-awareness. Study 2 assessed modeling honesty, positive consequences of honesty, and the combination of modeling and consequences. Some individual techniques worked for specific age groups: Self-awareness only increased 3-4-year-olds' and promising only increased 7-8-year-olds' honesty. However, the combination of modeling and consequences increased honesty for all age groups. Findings suggest that different motivational factors may encourage children's honesty across childhood.

RESUMEN

The current investigation examined the influence of a child's reputation on 7- to 12-year-olds' (Study 1; N = 146) and parents' (Study 2; N = 198) moral evaluations of the child's blunt truths (i.e., truths told despite possible hurt feelings) and prosocial lies (i.e., lies told to protect another's feelings). In Study 1, children were read a series of vignettes in which a child, described as being smart, kind, or clean (with clean serving as the irrelevant control reputation), told either the blunt truth or a prosocial lie that varied in content (opinions or facts). In Study 2, parents evaluated the same vignettes and reputations as in Study 1 with the addition of a troublemaker reputation. The reputation of the child protagonist significantly influenced both children's and parents' moral evaluations. Children rated the kind child's lies more positively, and parents rated the smart child's truths and lies less positively, than those of the clean (control) child when told about opinions. No differences were noted in the facts content condition. Findings suggest that a child's perceived reputation may influence both children's and adults' moral interpretations of the child's honesty behaviors.

RESUMEN

In the aftermath of discrete disasters, how families discuss the event has been linked with child well-being. There is less understanding, however, of how family communication affects adjustment to a protracted and ongoing public health crisis such as the COVID-19 pandemic. The present research leveraged a large longitudinal sample of families (N = 1884) across the United States and Canada to investigate factors that predicted family communication styles (active versus avoidant communication) about the COVID-19 pandemic and examined the longitudinal sequelae of mental health outcomes for youth associated with different family communication styles. Parents of youth between 5 to 17 years old completed surveys about their own mental health, their child's mental health, and family communication about the COVID-19 pandemic at two time points 6 months apart. Overall, findings indicated that poorer parental mental health was related to greater use of avoidant communication, and avoidant communication styles were associated with poorer youth mental health over time. Findings suggest potential perils of avoidant family communication about ongoing threats and can help identify families at risk of negative mental health outcomes.

RESUMEN

The objective of this study was to establish the accuracy of the resting calcaneal stance position (RCSP) for the assessment of flat foot (FF) in children, aligned to the validity of the foot posture index (FPI). The RCSP cut-off point was explored, in context of both FF prevalence and the relationship between FF and body weight. A total of 205 healthy children, aged 5 to 10 years, participated in a cross-sectional study. Correlation was performed between RCSP and FPI. ROC curve technique was calculated to assess differentiation between groups. A score equal to or greater than 7 on the FPI was used as the 'gold standard' for analysis. The correlation between FPI and RCSP was significant (r = 0.63; p < 0.01). The discrimination score on the ROC curve (6 points/degrees) shows that the model can be used to identify FF through RCSP, with a sensitivity of 67% and specificity of 85% returned.  Conclusion: The results of this study indicate the role of RCSP for simple, accessible and quick screening of paediatric FF. This is especially pertinent for non-podiatric healthcare professional without specialised paediatric foot knowledge. What is Known: • Most children develop a normal arch quickly, and flat feet usually resolve on their own between 2 and 6 years of age. • The measurement used to diagnose flat foot in children must be accurate, consistent, and valid to characterize the standard foot position. The Resting Calcaneal Stance Position (RCSP) is another widely used measure to evaluate the position of the flat foot in children. What is New: • The RCSP cut-off point 6 shows a sensitivity of 67% and a specificity of 85% thanks to the FPI as the Gold standard. • The RCSP is useful for health professionals who are not specialised in pediatric foot health. The RCSP is useful to detect flat foot in children.

RESUMEN

While previous studies have demonstrated correlations between children and adolescents' evaluations of lies and lie-telling behaviors, the temporal order of these associations over time and changes across this developmental period remain unexamined. The current study examined longitudinal associations among children and adolescents' (N = 1128; Mage = 11.54, SD = 1.68, 49.80% male, and 83.6% white) evaluations of lies to parents for autonomy and lie-telling frequency to parents and friends. Autoregressive cross-lagged analysis revealed longitudinal associations moderated by age. Among children, evaluations of lies predicted greater lie-telling rates over time. Conversely, among adolescents, lie-telling frequency predicted lie evaluations over time, and evaluations predicted lying to parents over time. These results demonstrate a novel developmental pattern of the associations between moral evaluations of lies and lie-telling. RESEARCH HIGHLIGHTS: Children and adolescents' evaluations of lie-telling and lie-telling frequency were associated longitudinally, but the direction of this association was moderated by age. Among children, more positive lie evaluations predicted greater lie-telling to parents and friends over time. Among adolescents, more positive lie evaluations predicted lying more often to parents over time; lying more to parents and friends predicted more positive evaluations over time. These findings suggest a novel developmental pattern regarding the temporal order of the association between evaluations of lie-telling and lie-telling frequency.

RESUMEN

Children were at a greater risk of adverse experiences, including maltreatment, during the COVID-19 pandemic given the increased stress experienced by families and reduced visibility outside the home. Child maltreatment investigators witnessed the effects of the pandemic on maltreated children and offer valuable insight regarding children's experiences during the pandemic. The objective of this study was to examine child maltreatment investigators' perspectives of the impact of the COVID-19 pandemic on maltreated children and their families in Canada. Sixteen child maltreatment investigators were recruited from agencies across Canada that investigate or offer services to children suspected of having been maltreated. Three focus groups were conducted, which followed a semi-structured interview guide developed by the researchers. Thematic analysis resulted in five primary themes regarding maltreatment investigators' perceptions of the pandemic's effects on children, including child maltreatment during the COVID-19 pandemic, increased exposure to violent and traumatic events, stress and challenges faced by families, reduced access to services, and challenges and delays with maltreatment investigations. Child maltreatment investigators perceived that the pandemic profoundly impacted maltreated children and their families. It is critical to ensure children and parents have access to services during future emergencies.

RESUMEN

Regardless of compliance to coercion by an alleged perpetrator, child maltreatment is abuse in any form. However, the extent to which coercion is described as an obligation (mandatory compliance) or permission (optional compliance) is legally relevant. The present investigation examined how attorneys question children about coercion and how children describe coercion in courtroom investigations of alleged child sexual abuse, and whether such language influences jurors' perceptions of children's testimony. Study 1 assessed 64 transcripts of children's testimonies and revealed that both attorneys and children use coercive language. Problematically, terms of permission were used when describing sexual abuse, potentially implying compliance was optional. Study 2 presented 160 adults with transcript excerpts, varied by coercive language (obligation or permission) and maltreatment type (sexual abuse or punishment). Coercive language influenced perceptions of coercion and whether the adult was to blame. Maltreatment type influenced perceptions of severity, credibility, and verdict. Overall, coercive language and maltreatment type influence perceptions of how the event unfolded.

RESUMEN

Adolescence has been suggested to be a time of heightened lie-telling. The current study used a latent profile analysis to examine unique patterns of lie-telling for lies told to parents and friends during adolescence as well as whether adjustment indicators (relationship quality, depressive symptoms, social anxiety, externalizing problems) could be used to predict group membership. These patterns were examined among 828 10- to 16- year-olds (Mage = 12.39, SD = 1.69, 49.9% male). In both relationships, 5-profile solutions emerged; most adolescents reported very infrequent lie-telling, while a small portion (less than 5%) told high rates of lies. Adjustment indicators predicted group membership. Depressive symptoms, social anxiety, parent relationship quality, and externalizing problems predicted group membership for lying to parents. Depressive symptoms and social anxiety predicted group membership for lying to friends. The findings indicate that high rates of lie-telling found in previous research may be driven by a small number of prolific lie-tellers.

RESUMEN

BACKGROUND: Sexual grooming in cases of child sexual abuse (CSA) has captured the attention of researchers over the past decades. While early research focused on offenders who groomed children in person, our knowledge of online groomers has begun to increase. However, there has not been a concomitant increase in understanding of groomers who use both in-person and online grooming strategies (i.e., mixed groomers); it is not clear if mixed groomers more closely resemble in-person groomers, online groomers, or if they are their own distinct groomer type. OBJECTIVE: The current study creates the first taxonomy of in-person, online, and mixed groomer profiles through the empirical analysis of Canadian judicial decisions. PARTICIPANTS, SETTING, AND METHODS: 180 Canadian judicial decisions from 153 cases of CSA involving grooming were extracted from the Canadian Legal Information Institute and coded for information related to grooming strategies, the accused, the complainant, and the alleged offence. RESULTS: Mixed groomers used more grooming strategies per case than in-person and online groomers. Mixed groomers initiated contact online with complainants less often than online groomers, but identified more vulnerable victims, engaged in more non-sexual yet inappropriate conversations, and used more gain cooperation strategies than in-person groomers. Online groomers were older and had shorter delays to criminal proceedings than mixed and in-person groomers. Complainants groomed in person were younger and abused for longer durations than mixed and online complainants. CONCLUSIONS: The proposed taxonomy of groomer profiles can inform education and prevention programs about the heterogeneous nature of grooming. Those who groomed children in-person, online, or using a mixture of both methods varied greatly in their grooming strategies, victim age preferences, relationship to the child, and pathways to disclosure.

RESUMEN

Cyanotoxins such as microcystin-LR (MC-LR) represent a global environmental threat to ecosystems and drinking water supplies. The study investigated the direct use of graphene as a rational interface for removal of MC-LR via interactions with the aromatic ring of the ADDA1 chain of MC-LR and the sp2 hybridized carbon network of graphene. Intra-particle diffusion model fit indicated the high mesoporosity of graphene provided significant enhancements to both adsorption capacities and kinetics when benchmarked against microporous granular activated carbon (GAC). Graphene showed superior MC-LR adsorption capacity of 75.4 mg/g (Freundlich model) compared to 0.982 mg/g (Langmuir model) for GAC. Sorption kinetic studies showed graphene adsorbs 99% of MC-LR in 30 min, compared to zero removal for GAC after 24 hr using the same MC-LR concentration. Density functional theory (DFT), calculations showed that postulated π-based interactions align well with the NMR-based experimental work used to probe primary interactions between graphene and MC-LR adduct. This study proved that π-interactions between the aromatic ring on MC-LR and graphene sp2 orbitals are a dominant interaction. With rapid kinetics and adsorption capacities much higher than GAC, it is anticipated that graphene will offer a novel molecular approach for removal of toxins and emerging contaminants with aromatic systems.

RESUMEN

Child interviewers are often advised to avoid asking "How" questions, particularly with young children. However, children tend to answer "How" evaluative questions productively (e.g., "How did you feel?"). "How" evaluative questions are phrased as a "How" followed by an auxiliary verb (e.g., "did" or "was"), but so are "How" questions requesting information about method or manner (e.g., "How did he touch you?"), and "How" method/manner questions might be more difficult for children to answer. We examined 458 5- to 17-year-old children questioned about sexual abuse, identified 2485 "How" questions with an auxiliary verb, and classified them as "How" evaluative (n = 886) or "How" method/manner (n = 1599). Across age, children gave more productive answers to "How" evaluative questions than "How" method/manner questions. Although even young children responded appropriately to "How" method/manner questions over 80% of the time, specific types of "How" method/manner questions were particularly difficult, including questions regarding clothing, body positioning, and the nature of touch. Children's difficulties lie in specific combinations of "How" questions and topics, rather than "How" questions in general.

RESUMEN

Clubfoot is a congenital anomaly affecting 1/1,000 live births. Ponseti casting is an effective and affordable treatment. About 75% of affected children have access to Ponseti treatment in Bangladesh, but 20% are at risk of drop-out. We aimed to identify the areas in Bangladesh where patients are at high or low risk for drop-out. This study used a cross-sectional design based on publicly available data. The nationwide clubfoot program: 'Walk for Life' identified five risk factors for drop-out from the Ponseti treatment, specific to the Bangladeshi setting: household poverty, household size, population working in agriculture, educational attainment and travel time to the clinic. We explored the spatial distribution and clustering of these five risk factors. The spatial distribution of children <5 years with clubfoot and the population density differ widely across the different sub-districts of Bangladesh. Analysis of risk factor distribution and cluster analysis showed areas at high risk for dropout in the Northeast and the Southwest, with poverty, educational attainment and working in agriculture as the most prevalent driving risk factor. Across the entire country, twenty-one multivariate high-risk clusters were identified. As the risk factors for drop-out from clubfoot care are not equally distributed across Bangladesh, there is a need in regional prioritization and diversification of treatment and enrolment policies. Local stakeholders and policy makers can identify high-risk areas and allocate resources effectively.

RESUMEN

OBJECTIVE: In Queensland, where a person experiences a major disturbance in their mental capacity, and is at risk of serious harm to self and others, an emergency examination authority (EEA) authorises Queensland Police Service (QPS) and Queensland Ambulance Service (QAS) to detain and transport the person to an ED. In the ED, further detention for up to 12 h is authorised to allow the examination to be completed. Little published information describes these critical patient encounters. METHODS: Queensland's Public Health Act (2005), amended in 2017, mandates the use of the approved EEA form. Data were extracted from a convenience sample of 942 EEAs including: (i) patient age, sex, address; (ii) free text descriptions by QPS and QAS officers of the person's behaviour and any serious risk of harm requiring urgent care; (iii) time examination period commenced; and (iv) outcome upon examination. RESULTS: Of 942 EEA forms, 640 (68%) were retrieved at three 'larger central' hospitals and 302 (32%) at two 'smaller regional' hospitals in non-metropolitan Queensland. QPS initiated 342 (36%) and QAS 600 (64%) EEAs for 486 (52%) males, 453 (48%) females and two intersexes (<1%), aged from 9 to 85 years (median 29 years, 17% aged <18 years). EEAs commonly occurred on weekends (32%) and between 2300 and midnight (8%), characterised by 'drug and/or alcohol issues' (53%), 'self-harm' (40%), 'patient aggression' (25%) and multiple prior EEAs (23%). Although information was incomplete, most patients (78%, n = 419/534) required no inpatient admission. CONCLUSIONS: EEAs furnish unique records for evaluating the impacts of Queensland's novel legislative reforms.

RESUMEN

Lie-telling and impulsivity levels peak during late childhood to early adolescence and have been suggested to be related. Heightened impulsivity may lead adolescents to lie in favor of short-term benefits without consideration for the potential consequences of deception. The present study assessed longitudinal relations between self-reported impulsivity and lie-telling frequency. Participants from a large-scale longitudinal study (N = 1148; Mage  = 11.55, SD = 1.69, 9-15 years at Time 1) reported on their impulsivity (Barratt Impulsiveness Scale) and their frequency of lie-telling to parents, to teachers, to friends, and about cheating across two time points 1 year apart. Cross-lagged path analysis revealed greater impulsivity was associated with more frequent lie-telling to parents, friends, and teachers, and about cheating over time. Our findings demonstrate the role of impulsivity in the development of lie-telling behaviors. RESEARCH HIGHLIGHTS: Impulsivity predicts lying across time in multiple contexts (to parents, friends, teachers, and about cheating). Previous research has demonstrated the role of top-down influences on lie-telling, but the current study suggests that bottom-up processes are also influential.

RESUMEN

PURPOSE: 131I-metaiodobenzylguanidine (131I-MIBG) has demonstrated efficacy as a single agent in neuroblastoma. Recent trials have focused on 131I-MIBG combination strategies, though little is known about the effect of putative radiosensitizers on biological markers of radiation exposure. METHODS AND MATERIALS: NANT2011-01 evaluated 131I-MIBG therapy alone (arm A) or in combination with vincristine/irinotecan (arm B) or vorinostat (arm C) for patients with relapsed or refractory neuroblastoma. Blood samples were collected before and after 131I-MIBG infusion to determine levels of radiation-associated biomarkers (transcript and protein). The association of biomarker with treatment arm, clinical response, and treatment toxicity was analyzed. RESULTS: The cohort included 99 patients who had at least 1 biomarker available for analysis. Significant modulation in most biomarkers between baseline, 72, and 96 hours following 131I-MIBG was observed. Patients in arm C had the lowest degree of modulation in FLT3 ligand protein. Lower baseline BCL2 transcript levels were associated with higher overall response. Patients with greater increases in FLT3 ligand at 96 hours after 131I-MIBG therapy were significantly more likely to have grade 4 thrombocytopenia. Peripheral blood gene expression of the BCL2 family of apoptotic markers (BCL2L1 and BAX transcripts) was significantly associated with grade 4 hematologic toxicity. RNA sequencing demonstrated little overlap in the top modulated peripheral blood transcripts between randomized arms. CONCLUSIONS: Peripheral blood biomarkers relevant to radiation exposure demonstrate significant modulation after 131I-MIBG and concomitant radiation sensitizers affect extent of modulation. Biomarkers related to hematopoietic damage and apoptosis were associated with hematologic toxicity.

RESUMEN

The aims of this study were as follows: (1) to assess how foot posture and morphology assessments change according to body mass index (BMI) status; (2) to determine which body composition parameter (BMI or waist circumference) correlates better with the foot posture index (FPI), arch height index (AHI), and midfoot width (MFW) in children. Foot morphometry (FPI, AHI, and MFW) and body composition (BMI and waist circumference (WC)) were assessed in a cross-sectional study of 575 children (mean age = 7.42 ± 1.67 years; 53.27% female). When comparing BMI groups, an increase of 8.3% in AHI and 13.6% in MFW (both p < 0.0001) was seen. In linear regression analyses, BMI and WC were positively associated with MFW explaining together 64.8% of its variance. Noteworthy, MFW is the most related to body composition parameters. CONCLUSION: Foot morphology assessed by FPI, AHI, and MFW differs among BMI categories in children. Noteworthy, WC correlates better with foot measures than does the more commonly used BMI, and more importantly the MFW is the foot measure best explained by children's body weight. Since foot morphometry is different among different BMI groups, children would benefit from shoes with different patterns (thinner and wider), as well as a good system to adjust midfoot height. WHAT IS KNOWN: • Children who are overweight and obese have flatter feet, when assessed using footprints. • Up to 72% of people have incorrectly fitted shoes. WHAT IS NEW: • Children with underweight have thinner and flatter feet than children with normal weight, while children with overweight and obesity have wider and higher arched feet. • Body weight is related to foot shape, which has relevance for footwear manufacturers.

RESUMEN

Adults' perceptions of children's disclosures have important implications for the response to that disclosure. Children who experience adult transgressions, such as maltreatment, often choose to disclose this experience to a peer. Thus, peer disclosure recipients may transmit this disclosure to an adult or provide support for the child's own disclosure. Despite this, the influence of peer disclosure on a child witness's credibility, as well as on the perceptions of peer disclosure recipients, is unknown. The present study examined how child witnesses' and peer disclosure recipients' credibility is impacted when the peer either confirms or contradicts the witness's disclosure (or concealment) of an adult transgression. Participants listened to a child witness and peer being interviewed by an adult in one of four disclosure patterns (consistent disclose, consistent conceal, witness disclose/peer conceal, or witness conceal/peer disclose). Participants rated both the witness and the peer on dimensions of credibility (honesty and cognitive competence). Results revealed that both the witness and peer were more credible when their reports were consistent with one another. When inconsistent, the witness/peer who disclosed was considered more credible than the one who concealed. The findings indicate the potential importance of peers in the disclosure process as they may support the witness's report and even be a credible discloser when the witness is reluctant to disclose.

RESUMEN

Forensic interviewers ask children broad input-free recall questions about individual episodes in order to elicit complete narratives, often asking about "the first time," "the last time," and "one time." An overlooked problem is that the word "time" is potentially ambiguous, referring both to a particular episode and to conventional temporal information. We examined 191 6-9-year-old maltreated children's responses to questions about recent events varying the wording of the invitations, either asking children to "tell me about" or "tell me what happened" one time/the first time/the last time the child experienced recent recurrent events. Additionally, half of the children were asked a series of "when" questions about recurrent events before the invitations. Children were several times more likely to provide exclusively conventional temporal information to "tell me about" invitations compared to "tell me what happened" invitations, and asking "when" questions before the invitations increased children's tendency to give exclusively conventional temporal information. Children who answered a higher proportion of "when" questions with conventional temporal information were also more likely to do so in response to the invitations. The results suggest that children may often fail to provide narrative information because they misinterpret invitations using the word "time."

RESUMEN

Introduction: Missions beyond low Earth orbit (LEO) will expose astronauts to ionizing radiation (IR) in the form of solar energetic particles (SEP) and galactic cosmic rays (GCR) including high atomic number and energy (HZE) nuclei. The gastrointestinal (GI) system is documented to be highly radiosensitive with even relatively low dose IR exposures capable of inducing mucosal lesions and disrupting epithelial barrier function. IR is also an established risk factor for colorectal cancer (CRC) with several studies examining long-term GI effects of SEP/GCR exposure using tumor-prone APC mouse models. Studies of acute short-term effects of modeled space radiation exposures in wildtype mouse models are more limited and necessary to better define charged particle-induced GI pathologies and test novel medical countermeasures (MCMs) to promote astronaut safety. Methods: In this study, we performed ground-based studies where male and female C57BL/6J mice were exposed to γ-rays, 50 MeV protons, or 1 GeV/n Fe-56 ions at the NASA Space Radiation Laboratory (NSRL) with histology and immunohistochemistry endpoints measured in the first 24 h post-irradiation to define immediate SEP/GCR-induced GI alterations. Results: Our data show that unlike matched γ-ray controls, acute exposures to protons and iron ions disrupts intestinal function and induces mucosal lesions, vascular congestion, epithelial barrier breakdown, and marked enlargement of mucosa-associated lymphoid tissue. We also measured kinetics of DNA double-strand break (DSB) repair using gamma-H2AX- specific antibodies and apoptosis via TUNEL labeling, noting the induction and disappearance of extranuclear cytoplasmic DNA marked by gamma-H2AX only in the charged particle-irradiated samples. We show that 18 h pre-treatment with curcumin-loaded nanolipoprotein particles (cNLPs) delivered via IV injection reduces DSB-associated foci levels and apoptosis and restore crypt villi lengths. Discussion: These data improve our understanding of physiological alterations in the GI tract immediately following exposures to modeled space radiations and demonstrates effectiveness of a promising space radiation MCM.

RESUMEN

Research has explored age-related and cultural differences in moral evaluations of dishonesty; however, this has not yet been examined in an aging context. The present study provided a novel account of how younger and older adults (in Canada, Singapore, and China; N = 401) morally evaluate adults' truths and lies in antisocial, modesty, and politeness settings. Participants completed a questionnaire assessing how acceptable it is for adults to tell the truth or a lie in given social scenarios, and they reported on their levels of collectivism and individualism. In all countries, older adults provided more favorable evaluations to blunt and immodest truths than younger adults did. Compared with younger adults, older adults provided harsher evaluations to Polite Lies (in Canada and China) and Modesty Lies (in Canada and Singapore). Thus, there may be an age-related increase in the acceptability of direct honesty over good-intentioned lies, and this age effect is somewhat stable across cultures. Older adults were also more lenient in evaluations of an antisocial lie to conceal an affair compared to younger adults. Overall, adults in China tended to rate lies less negatively, and their greater levels of collectivism mediated their greater approval of polite lies. The present results demonstrate that evaluations of (dis)honesty differ as a function of age and culture and these results can assist in developing a more complete lifespan model of the morality of dishonesty.
