Although the impact of early adverse experience on neural processing of face familiarity has been studied, research has not taken into account disordered child behavior. This work compared the neural processing of familiar versus strangers' faces in 47 institutionalized children with a mean age of 54 months to determine the effects of (a) the presence versus absence of atypical social behavior and (b) inhibited versus indiscriminant atypical behavior. Results revealed a pattern of cortical hypoactivation in institutionalized children manifesting atypical social behavior and that inhibited children displayed larger neural response to a caregiver's face than to the stranger's, while indiscriminant children did not discriminate between stimuli. These findings suggest that neural correlates of face familiarity are associated with social functioning in institutionalized children.  相似文献

IntroductionEpithelial cells (ECs) are structures regularly observed during urine microscopy analysis. The correct identification of EC subtypes can be useful since renal tubular epithelial cells (RTECs) are clinically relevant. We investigate the urinary ECs report and the judgement of its clinical importance by Brazilian laboratories.Materials and methodsA survey with four questions was made available to participants of the Urinalysis External Quality Assessment Program (EQAP) from Controllab. Laboratories composed 3 groups: (1) differentiating ECs subtypes: “squamous”, “transitional” and “RTECs”; (2) differentiating ECs subtypes: “squamous” or “non-squamous” cells; (3) without ECs subtype identification. Participants did not necessarily answer to all questions and the answers were evaluated both within the same laboratory’s category and within different categories of laboratories.ResultsA total of 1336 (94%) laboratories answered the survey; Group 1, 119/140 (85%) reported that ECs differentiation is important to the physician and 62% want to be evaluated by EQAP, while in Group 3, 455/1110 (41%) reported it is useful to them, however only 25% want be evaluated by EQAP. Group 2 laboratories 37/51 (73%) reported that the information is important, but only 13/52 (25%) are interested in an EQAP with differentiation of the 3 ECs subtypes.ConclusionMost of the laboratories do not differentiate ECs in the three subtypes, despite the clinical importance of RTECs. Education of laboratory staff about the clinical significance of urinary particles should be considered a key priority.  相似文献   

Evaluation of two interventions to reduce aggressive and antisocial behavior in first and second graders in a resource-poor setting     

Joanne Klevens  José William Martínez  Brenda Le  Carlos Rojas  Adriana Duque  Rafael Tovar 《International Journal of Educational Research》2009,48(5):307-319

We conducted a three-arm cluster randomized controlled trial (n = 2491) to evaluate a teacher delivered intervention to reduce aggressive and antisocial behavior and increase prosocial behavior in the classroom. A second aim of this trial was to establish whether combining this intervention with an intervention for parents was better than the teacher-only intervention. This evaluation was conducted in a resource-poor setting (Pereira, Colombia). The findings show that both interventions prevented increases in aggressive and antisocial behavior. However, the teacher-only intervention also had a positive impact on increasing prosocial behavior.  相似文献   

Methodological Issues in Ethnic and Racial Identity Research With Ethnic Minority Populations: Theoretical Precision,Measurement Issues,and Research Designs     

Seth J. Schwartz  Moin Syed  Tiffany Yip  George P. Knight  Adriana J. Uma?a‐Taylor  Deborah Rivas‐Drake  Richard M. Lee  Ethnic  Racial Identity in the st Century Study Group 《Child development》2014,85(1):58-76

This article takes stock of research methods employed in the study of racial and ethnic identity with ethnic minority populations. The article is presented in three parts. The first section reviews theories, conceptualizations, and measurement of ethnic and racial identity (ERI) development. The second section reviews theories, conceptualizations, and measurement of ERI content. The final section reviews key methodological and analytic principles that are important to consider for both ERI development and content. The article concludes with suggestions for future research addressing key methodological limitations when studying ERI.  相似文献   

Family Context,Mexican‐Origin Adolescent Mothers' Parenting Knowledge,and Children's Subsequent Developmental Outcomes     

Laudan B. Jahromi  Amy B. Guimond  Adriana J. Umaña‐Taylor  Kimberly A. Updegraff  Russell B. Toomey 《Child development》2014,85(2):593-609

This study examined parenting knowledge among Mexican‐origin adolescent mothers (N = 191; M_age = 16.26 years), family contextual factors associated with adolescents' parenting knowledge, and toddlers' (M_age = 2.01 years) subsequent developmental outcomes. Data came from home interviews and direct child assessments. Adolescents both underestimated and overestimated children's developmental timing, and showed differences in their knowledge of specific developmental domains. Instrumental support from mother figures was positively linked to adolescents' knowledge accuracy, whereas emotional support was negatively related to adolescents' knowledge confidence. Furthermore, whereas mother figures' autonomy granting was positively linked to knowledge confidence, psychological control was associated with less accurate adolescent parenting knowledge. Toddlers of adolescents with more accurate knowledge showed positive developmental functioning. Intervention implications are discussed.  相似文献   

A hybrid approach to university subject learning activities     

Luz Adriana Osorio Gómez  Josep M. Duart 《British journal of educational technology : journal of the Council for Educational Technology》2012,43(2):259-271

In order to get a better understanding of subject design and delivery using a hybrid approach, we have studied a hybrid learning postgraduate programme offered by the University of the Andes, Bogotá, Colombia. The study analyses students' perceptions of subject design and delivery, with particular reference to learning activities and the roles of lecturers and students during moments of interaction. Elements of socio‐cultural activity theory were taken as a reference for subject analysis. It is a qualitative research project containing some quantitative data. For the purposes of the study, the following instruments were designed and applied: a student survey, student interviews (by subject), lecturer interviews, and a subject design and planning observation guide. The study's conclusions present the characteristics of learning activities and of student–lecturer and student–student interaction that fostered the attainment of subject learning objectives. These characteristics can make a positive contribution to the process of subject design and delivery using a hybrid approach, meaning integration between face‐to‐face and e‐learning actions in the delivery of learning activities.  相似文献   

Mexican-Origin Adolescent Mothers’ Economic Contexts,Educational Re-Engagement,and Their Children’s School Readiness     

Elana R. McDermott  Laudan B. Jahromi  Adriana J. Umaña-Taylor  Stefanie Martinez-Fuentes  Shandra M. Jones  Kimberly A. Updegraff 《Child development》2021,92(4):e513-e530

Drawing on data from a longitudinal study of 204 Mexican-origin adolescent mothers, their mother figures, and their children, the current investigation examined (a) adolescent mothers’ educational re-engagement and attainment beginning during their pregnancy and ending when their child was 5 years old; and (b) the influence of the family economic context on adolescent mothers’ educational re-engagement and attainment and their children’s academic and social-emotional outcomes. Findings detailed adolescent mothers’ re-engagement in school after the birth of their child and revealed that family income during adolescents’ pregnancies was directly associated with re-engagement and attainment, and also initiated cascade effects that shaped adolescents’ economic contexts, their subsequent re-engagement and attainment, and ultimately their children’s academic and social-emotional outcomes at age 5.  相似文献   

Counseling in Nigeria and the United States of America: Contrasts and Similarities     

Oyaziwo?Aluede  Adriana?G.?McEachern  Maureen?C.?KennyEmail author 《International journal for the advancement of counseling》2005,27(3):371-382

This paper compares the profession of counseling in Nigeria and the United States of America (USA). Many differences exist in the practice of counseling in these two countries, including a greater emphasis on specialization, credentialing and licensing in the USA. Issues such as lack of insurance coverage and general economic disadvantage affect the utilization of counseling services in Nigeria. Although both countries are dealing with similar societal concerns, training standards remain localized. The authors recommend that given the global nature of counseling's reach and potential impact across the world, efforts should be made to implement international credentialing standards.  相似文献

Establishing paediatric reference intervals for thyroid function tests in Croatian population on the Abbott Architect i2000     

Adriana Bokuli&#x;  Ivana Zec  Domagoj Marijan evi&#x;  Sanja Goreta  Marija Pogaj &#x;epec  Lavinia La Grasta Saboli&#x; 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2021,31(3)

IntroductionEvaluation of thyroid function is often requested and therefore defining paediatric reference intervals (RIs) is of vital importance. Currently, there is a distinct lack of paediatric RIs for thyroid function tests in Croatia. Thus, we established RIs for thyroid stimulating hormone (TSH), total triiodothyronine (TT3), total thyroxine (TT4), free triiodothyronine (FT3) and free thyroxine (FT4) in the Croatian paediatric population.Materials and methodsReference intervals were calculated from 397 apparently healthy children, aged from 2 days to < 19 years. Serum samples were analysed for thyroid function tests on the Abbott Architect i2000. Age- and sex-specific 95% RIs with 90% confidence intervals were established according to Clinical and Laboratory Standards Institute guidelines. To express the magnitude of sex and age variation, standard deviation ratio (SDR) was calculated using two-level nested ANOVA. The criterion for considering partitioning reference values was set to SDR > 0.3.ResultsAll thyroid function tests required age partitioning, confirmed by SDR above 0.3. There was no need for sex partitioning, confirmed by SDR below 0.3. Still, FT3 was partitioned due to visually noticeable sex related difference for the oldest group (12 years to < 19 years).ConclusionThis is the first study to establish RIs for thyroid function tests in the Croatian paediatric population. We propose RIs for widely used Abbott platform, thus giving laboratories method- and population-specific paediatric RIs for thyroid function tests that should improve clinical test interpretation.  相似文献
