Acculturation,self-efficacy and social support among Chinese immigrants in Northern Ireland

An opportunity sample of 108 Chinese participants (n_male = 51 and n_female = 57; M_age = 29.34) was compared to a second opportunity sample of 98 Northern Irish participants (n_male = 45 and n_female = 53; M_age = 23.67) on levels of acculturation, self-efficacy and social support. The administered questionnaire contained three scales to measure the aforementioned constructs. The first was the AMAS-NIC, a version of the Abbreviated Multidimensional Acculturation Scale [Zea, M. C., Asner-Self, K. K., Birman, D., & Buki, L. P. (2003). The Abbreviated Multidimensional Acculturation Scale: Empirical validation with two Latino/Latina samples. Cultural Diversity and Ethnic Minority Psychology, 9, 107–126] modified to apply to a population of Chinese immigrants in Northern Ireland. The second measure was Mary Wegner's 1992 English version of the General Self-Efficacy Scale [Wright, S., Johnston, M., & Weinman, J. (1995). Measures in health psychology portfolio. UK: Windsor]. The third was the Social Support Questionnaire (SSQ) whose items emerged through a semi-structured interview and was designed to measure levels of received and sought social support. The purpose of the study was to ascertain the extent to which previous findings concerning acculturation can be generalised to a Chinese immigrant population in Northern Ireland, a country characterised by segregation. T-tests, correlation analyses and a hierarchical regression initially provided support for the generalisability of previous studies on the health benefits of integration as a preferred acculturation strategy [Berry, J. W. (2008). Globalisation and acculturation. International Journal of Intercultural Relations, 32, 328–336], but further interpretation of the results brought to light the shortcomings of this model in the context of a segregated society and the inapplicability of the GSES measure within a collectivistic immigrant population. The limitations of the study are discussed and recommendations for future research are made.     

Construct validation of physical activity surveys in culturally diverse older adults: a comparison of four commonly used questionnaires

The purpose of this study was to establish validity evidence of four physical activity (PA) questionnaires in culturally diverse older adults by comparing self-report PA with performance-based physical function. Participants were 54 older adults who completed the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), Physical Activity Scale for the Elderly (PASE), HAMPS Physical Activity Questionnaire for Older Adults, Yale Physical Activity Survey (YPAS), and modified Baecke questionnaire. The total PASE score, three outcome scores for the CHAMPS, and three summary indices for the YPAS were significantly correlated with total CS-PFP10 score. The modified Baecke exhibited no correlations with CS-PFP10 scores. The PASE, CHAMPS, and YPAS appear to be the most valid PA self-report questionnaires for culturally diverse older adults.     

What is modelled during observational learning?

In this article, we examine the question of what information is processed during observational learning by evaluating a variety of methods, theories, and empirical data. Initially, we review work involving neuroimaging techniques and infant imitation. We then evaluate data from behavioural experiments involving adults, wherein a variety of attempts have been made to isolate the critical or minimal information constraining the acquisition of coordination. This body of research has included comparisons between video and point-light displays, manipulations to the amount and type of information presented in the display, the collection of point-of-gaze data, and manipulations to the task context in terms of outcome goals. We conclude that observational learning is governed by specific features of the model's action (i.e. motions of the end effector) and the task (i.e. outcome constraints) and, in contrast with traditional theoretical modelling, more global aspects of a model (i.e. the relative motions within and between joints) do not appear to be the primary method for constraining action execution.     

How technology for comprehension training can support conversation towards the joint construction of meaning

Two studies assessed the role of Separate Control of Shared Space (SCoSS) technology in supporting peer collaborative discussion and comprehension. We hypothesised that providing equitable shared input to two literacy tasks (both good predictors of comprehension skill) would support discussion to promote the joint construction of meaning, and hence individual progress. Study 1: 50 7–9‐year‐olds took a reading‐specific multiple classification (RMC) pre‐test, categorising words on two dimensions, before training on the task in pairs using SCoSS, dual‐control or individual technology. Discussion produced more accurate post‐test classification performance and SCoSS was associated with higher frequency of statements during training that combined both RMC dimensions (surface form and meaning of words). Study 2: 12 8–9‐year‐olds were pre‐tested on story recall and worked in pairs on a SCoSS‐supported story construction task, requiring collaborative inference‐making, hypothesis generation and selection. Post‐test story recall was predicted by the frequency of deductive causal statements during training. We discuss how technology can be used to promote collaboration and discussion that supports joint understanding and individual comprehension development.     

A Case Study in Indigenous Classification: Revisiting and Reviving the Brian Deer Scheme

It is a challenge to classify Indigenous knowledge using conventional library classification systems. An interconnected network of information and ideas needs to be classified in a way that adds structure, but also demonstrates relationships and offers some flexibility. Kahnawake librarian Brian Deer developed a classification system that better reflects an Indigenous worldview and the Union of British Columbia Indian Chiefs Resource Centre recently released a new revision of this system. Implementing this new system was a project that produced a model and tools, as well as inspiration that other institutions can use to move toward more culturally appropriate classification.     

Physiological determinants of speciality of elite middle- and long-distance runners

The aim of this study was to determine which physiological variables predict excellence in middle- and long-distance runners. Forty middle-distance runners (age 23 ± 4 years, body mass 67.2 ± 5.9 kg, stature 1.80 ± 0.05 m, VO(2max) 65.9 ± 4.5 ml · kg(-1) · min(-1)) and 32 long-distance runners (age 25 ± 4 years, body mass 59.8 ± 5.1 kg, stature 1.73 ± 0.06 m, VO(2max) 71.6 ± 5.0 ml · kg(-1) · min(-1)) competing at international standard performed an incremental running test to exhaustion. Expired gas analysis was performed breath-by-breath and maximum oxygen uptake (VO(2max)) and two ventilatory thresholds (VT(1) and VT(2)) were calculated. Long-distance runners presented a higher VO(2max) than middle-distance runners when expressed relative to body mass (P < 0.001, d = 1.18, 95% CI [0.68, 1.68]). At the intensities corresponding to VT(1) and VT(2), long-distance runners showed higher values for VO(2) expressed relative to body mass or %VO(2max), speed and oxygen cost of running (P < 0.05). When oxygen uptake was adjusted for body mass, differences between groups were consistent. Logistic binary regression analysis showed that VO(2max) (expressed as l · min(-1) and ml · kg(-1) · min(-1)), VO(2VT2) (expressed as ml · kg(-0.94) · min(-1)), and speed at VT(2) (v(VT2)) categorized long-distance runners. In addition, the multivariate model correctly classified 84.7% of the athletes. Thus, VO(2max), VO(2VT2), and v(VT2) discriminate between elite middle-distance and long-distance runners.     

Learning from the experts: gaining insights into best practice during the acquisition of three novel motor skills

The amount and quality of practice predicts expertise, yet optimal conditions of practice have primarily been explored with novice learners. Ten expert musicians and ten novices practiced disc-throwing skills under self-regulated conditions. A third novice group practiced with the same schedule as the music experts (yoked). The groups did not differ in terms of the amount of contextual interference, only in terms of when in-practice interference was introduced. The music experts progressed from a more blocked to random schedule which was opposite to the novices. This resulted in more accurate performance in retention for the experts in comparison to both novice groups (self-scheduled and yoked). The music expert and yoked groups showed higher form scores than the novice self-scheduled group, which might be related to the greater frequency of augmented information for these groups. There was no evidence that non-task-domain experts choose a more random practice schedule than novices, but in accord with good practice principles, they gradually introduced high amounts of interference into their practice. This strategy was associated with less error in retention for the experts. Because the yoked group showed more error than the music experts, the advantage of this schedule was also performance dependent.     

Heirs and Spares: Elite Fathers and Their Sons in the Literary Sources of Umayyad Iberia

ABSTRACT

In the medieval Islamic world, elite men were the benchmark of hegemonic masculinity and social power. A presumption of masculine authority within the household shaped the way early medieval rulers were described by chroniclers, and how medieval fathers related to their sons. The formal and informal ways in which they interacted with lower status men – whether their clients, their courtiers, or their sons – were hedged about with the symbolic language of gender. The article focuses on the ways in which certain Andalusī literary sources talk about relations of fathers and their sons with the ruling Umayyad family, to offer an additional dimension to our picture of how the dynasty conceptualised and legitimised its power.     

Predictors of multiple injuries in individual distance runners: A retrospective study of 75,401 entrants in 4 annual races–SAFER XX

BackgroundThere are limited data on factors that predict an increased risk of multiple injuries among distance runners. The objective of this study was to determine risk factors that are predictive of individual runners with a high annual multiple injury risk (MIR).MethodsA retrospective, cross-sectional study at 4 annual (2012–2015) Two Oceans 21.1 km and 56.0 km races in South Africa with 75,401 consenting race entrants. Running-related injury data were collected retrospectively through an online pre-race medical screening questionnaire. The average number of injuries for each runner every year was calculated by taking a runner''s race entry history and injury history into account and categorizing entrants into 4 MIR categories (high, intermediate, low, and very low (reference)). Multiple logistic regression modeling (odds ratios) was used to determine whether the following factors were predictive of a high MIR (average > 1 injury/year): demographics, training and racing, chronic-disease history (composite chronic disease score (CCDS)), and history of allergies.ResultsOf all entrants, 9.2% reported at least 1 injury, and 0.4% of entrants were in the high MIR category; the incidence rate was 2.5 injuries per 10 runner-years (95% confidence interval (95%CI): 2.4–2.7). Significant factors predictive of runners in the high MIR category were: running for > 20 years: OR = 2.0 (95%CI: 1.3–3.1; p = 0.0010); a higher CCDS: OR = 2.2 (95%CI: 2.0–2.4; p < 0.0001); and a history of allergies: OR = 2.8 (95%CI: 2.0–3.8; p < 0.0001).ConclusionRunners who have been running recreationally for > 20 years and those with multiple chronic diseases or a history of allergies were at higher risk of multiple running-related injuries. This high-risk group can be targeted for further study and possible injury-prevention interventions.
