Nursing students' anxiety and clinical performance

This study examined how mood states affect nursing students' performance on a treatment procedure consisting of a novel combination of familiar clinical steps. Thirty third-year and fourth-year nursing students were first taught the procedure and then given both an anxious-mood and a calm-mood induction in a randomly assigned counterbalanced order. Anxiety was induced by showing a video of interviews with frontline nurses and doctors during the severe acute respiratory syndrome epidemic in Hong Kong, China; calmness was induced by a video of a nursing student's pleasant orientation to a clinical placement site. Nursing students were significantly less proficient in performing the newly acquired procedure after an anxious-mood induction (focused on occupational risks) than after a calm-mood induction. Therefore, managing clinical training site anxiety among nursing students may help to optimize learning and clinical performance. © SLACK Incorporated.postprin

Exploring the developmental changes in automatic two-digit number processing

Even when two-digit numbers are irrelevant to the task at hand, adults process them. Do children process numbers automatically, and if so, what kind of information is activated? In a novel dot-number Stroop task, children (Grades 1-5) and adults were shown two different two-digit numbers made up of dots. Participants were asked to select the number that contained the larger dots. If numbers are processed automatically, reaction time for dot size judgment should be affected by numerical characteristics. The results suggest that, like adults, children process two-digit numbers automatically. Based on the current findings, we propose a developmental trend for automatic two-digit number processing that goes from decomposed sequential (activation of decade digit followed by that of unit digit) to decomposed parallel processing (simultaneous activation of decade and unit digits). © 2011 Elsevier Inc.postprin

How do different training tasks modulate our perception and hemispheric lateralization in the development of perceptual expertise?

Conference Theme: Mind, Technology, and SocietyHolistic processing (HP) and hemispheric lateralization are both expertise markers of object recognition. For example, expertise in face and sub-ordinate object perception is shown to be associated with HP and stronger right hemispheric lateralization. However, HP is modulated by experiences of selective attention to parts such as writing experiences of Chinese characters (Tso, Au, & Hsiao, 2014) and drawing experiences of faces (Zhou et al., 2011). Meanwhile, hemispheric lateralization is associated with the decoding strategy employed in object recognition, such as left hemispheric lateralization for reading alphabetic scripts and right hemispheric lateralization for reading logographic scripts. This study aims at training participants to recognize the same sets of artificially-created scripts using either whole-word (Logographic) or grapheme-to-phoneme (Alphabetic) approaches. We found that both approaches induced strong HP, though the alphabetic approach induced stronger left hemisphere advantage than the logographic approach. This training study demonstrates that HP and hemispheric lateralization are separate processes that are associated with different perceptual mechanisms.postprin

Young children's analogical reasoning across cultures: Similarities and differences

A cross-cultural comparison between U.S. and Hong Kong preschoolers examined factors responsible for young children's analogical reasoning errors. On a scene analogy task, both groups had adequate prerequisite knowledge of the key relations, were the same age, and showed similar baseline performance, yet Chinese children outperformed U.S. children on more relationally complex problems. Children from both groups were highly susceptible to choosing a perceptual or semantic distractor during reasoning when one was present. Taken together, these similarities and differences suggest that (a) cultural differences can facilitate better knowledge representations by allowing more efficient processing of relationally complex problems and (b) inhibitory control is an important factor in explaining the development of children's analogical reasoning. © 2009 Elsevier Inc.

Fabrication and Characterization of Locally Woven Polyester Fibre Reinforced Polyester Composites

Properties of composite moulded using locally woven polyester fibre werestudied. The results showed that though properties of polyester resin were improved upon, but were far lower than composites obtained using fibre such as glass. The density of the composite was low compared to glass fibre reinforced composite. The composite moulded at pressure of 388.132kN/m2has the best properties; tensile strength 85MN/m2, modulus of elasticity 1.846GN/m2, impact strength 227.5kJ/m2 and modulus of rupture 9.910GN/m2

The validity of observational measures in detecting optimal maternal communication styles: Evidence from European Americans and Latinos

This study examined the sensitivity of an observational coding system for assessing positive and negative maternal behaviors of Latino and European American mothers toward their adolescent children. Ninety Latino (54 Spanish speaking and 35 English speaking) and 20 European American mother-adolescent dyads participated in an observational study of conversations about sexuality, AIDS, and conflicts. Associations were examined between observed maternal positive and negative behaviors and adolescent-reported relationship quality. Results indicated that maternal negative responsiveness was negatively associated with relationship quality for all ethnic/language groups. However, maternal positive responsiveness was related to relationship quality for European Americans but not for Latinos. These findings suggest a need for a broader definition of positive parenting in Latino families. © Copyright © 2007, Society for Research on Adolescence.postprin

Nasopharyngeal carcinoma: time lapse before diagnosis and treatment

This is a descriptive study of 168 patients with nasopharyngeal carcinoma who were referred to public oncology departments for primary treatment between July and September 1996. The mean duration from the onset of the symptoms to histological diagnosis was 5.0 months; the duration ranged from 6.1 months (for patients presenting with nasal symptoms) to 1.8 months (for those with cranial nerve dysfunction). The mean period between the onset of symptoms and the seeking of medical advice was 2.9months. For 54% of the patients, there was a further delay of up to 2.4 months between the initial medical consultation and referral to the appropriate specialist. The majority (84%) of patients attended public institutions for histological confirmation. The mean total time taken from the onset of symptoms to the commencement of radiotherapy was 6.5 months (range, 1.3-74.0 months)---45% of the delay was attributed to the patient, 20% to initial consultations, 14% to diagnostic arrangement, and 21% to preparation for radiotherapy. Concerted efforts are needed to minimise further the time between the onset of symptoms and treatment. A substantial reduction in this delay can be achieved if both public and primary care doctors were made more aware of the significance of relevant symptoms.published_or_final_versio

Identification of novel porcine and bovine parvoviruses closely related to human parvovirus 4

Human parvovirus 4 (PARV4), a recently discovered parvovirus found exclusively in human plasma and liver tissue, was considered phylogenetically distinct from other parvoviruses. Here, we report the discovery of two novel parvoviruses closely related to PARV4, porcine hokovirus (PHoV) and bovine hokovirus (BHoV), from porcine and bovine samples in Hong Kong. Their nearly full-length sequences were also analysed. PARV4-like viruses were detected by PCR among 44.4% (148/333) of porcine samples (including lymph nodes, liver, serum, nasopharyngeal and faecal samples), 13% (4/32) of bovine spleen samples and 2% (7/362) of human serum samples that were sent for human immunodeficiency virus and hepatitis C virus antibody tests. Three distinct parvoviruses were identified, including two novel parvoviruses, PHoV and BHoV, from porcine and bovine samples and PARV4 from humans, respectively. Analysis of genome pequences from seven PHoV strains, from three BHoV strains and from one PARV4 strain showed that the two animal parvoviruses were most similar to PARV4 with 61.5-63% nt identities and, together with PARV4 (HHoV), formed a distinct cluster within the family Parvoviridae. The three parvoviruses also differed from other parvoviruses by their relatively large predicted VP1 protein and the presence of a small unique conserved putative protein. Based on these results, we propose a separate genus, Hokovirus, to describe these three parvoviruses. The co-detection of porcine reproductive and respiratory syndrome virus, the agent associated with the recent 'high fever' disease outbreaks in pigs in China, from our porcine samples warrants further investigation. © 2008 SGM.published_or_final_versio
