Acquisition Of Expertise

The pedagogical literature strongly suggests that when a musician works on a specific piece of repertoire, one should choose practice strategies tailored to the challenges presented by that material. Such a behavioral choice could represent an instantiation of focused and deliberate practice, a critical aspect of the relationship between experience and the acquisition of expertise. However, most of the literature investigating individual practice has used a single stimulus for all participants, or else has employed surveys or other proxy measures of practicing behavior. In this study, participants of three different experience levels (high school, collegiate, or professional violinists) practiced three excerpts, each featuring a different signature challenge. Results suggest that practice is highly idiosyncratic, that participants do adjust their approaches to the challenges of the material, but that individuals of differing experience levels identify remarkably similar problems within the material.

Abstract Frailty is a clinical syndrome that becomes increasingly common as people age. Subjective age refers to how young or old individuals experience themselves to be. It is associated with many risk factors of frailty, such as increased depression, worse cognitive function, and poorer psychological wellbeing. In this study, we examined the relationship between subjective age and frailty using the 2011-2015 waves of the National Health and Aging Trends Study. Participants were community-dwelling older adults without frailty in the initial wave (N=1,165). Subjective age was measured by asking participants, “What age do you feel most of the time?” Based on the Fried five phenotypic criteria: exhaustion, unintentional weight loss, low physical activity, slow gait, and weak grip strength, frailty was categorized into robust=0, pre-frail=1 or 2; frail=3 or more criteria met. Participants were, on average, 74.1±6.5 years old, female (52%), and non-Hispanic White (81%). Eighty-five percent of the participants felt younger, and 3% felt older than their chronological age, but 41% of them were pre-frail/frail. Generalized estimating equations revealed that an “older” subjective age predicted a higher likelihood of pre-frailty and frailty (OR, 95%CI= 1.01, 1.01-1.02). In contrast, frailty predicted an “older” subjective age (OR, 95%CI= 2.97, 1.65-5.35) adjusting for demographics and health conditions. These findings suggest a bidirectional relationship between subjective age and frailty. Older people who feel younger than their chronological age are at reduced risk of becoming pre-frail/frail. Intervention programs to delay frailty progression should include strategies that may help older adults perceive a younger subjective age.

Abstract Anxiety and depression are one of the most distressing symptoms for the family caregivers. Little is known about the relationship between sleep impairments and anxiety/depression in this population and how objective and subjective sleep measures differ in relation to anxiety. This study was designed to examine the relationship between sleep impairments and anxiety/depression in people with dementia, using both subjective and objective sleep measures. Among the 170 study participants, 50% (n=85) reported to have anxiety/depression. In univariate logistic regression analyses on anxiety/depression, adjusting for dementia stage, people with more subjective sleep impairment had higher odds of having anxiety/depression (OR=1.111; 95% CI: 1.020-1.211, p=0.016) and people with poorer subjective sleep quality had higher odds of having anxiety/depression (OR=1.702; 95% CI: 1.046-2.769, p=0.032). Objective sleep measures from actigraphy did not show any significant relationships to anxiety/depression. The results suggest that subjective sleep measures are closely related to anxiety/depression in this population.

This study was conducted to evaluate the competency to consent to the treatment of psychiatric outpatients and to confirm the role of empowerment and emotional variables in the relationship between competency to consent to treatment and psychological well-being. The study participants consisted of 191 psychiatric outpatients who voluntarily consented to the study among psychiatric outpatients. As a result of competency to consent to treatment evaluation, the score of the psychiatric outpatient’s consent to treatment was higher than the cut-off point for both the overall and sub-factors, confirming that they were overall good. In addition, the effect of the ability of application on psychological well-being among competency to consent to treatment was verified using PROCESS Macro, and the double mediation effect using empowerment and emotional variables was verified to provide an expanded understanding of this. As a result of the analysis, empowerment completely mediated the relation between the ability of application and psychological well-being, and the relation between the ability of application and psychological well-being was sequentially mediated by empowerment and emotion-related variables. Based on these findings, the implications and limitations of this study were discussed.

Background: There are different types of hand motions in people’s daily lives and working environments. However, testing duration increases as the types of hand motions increase to build a normative database. Long testing duration decreases the motivation of study participants. The purpose of this study is to propose models to predict pinch and press strength using grip strength. Methods: One hundred ninety-eight healthy volunteers were recruited from the manufacturing industries in Central Taiwan. The five types of hand motions were grip, lateral pinch, palmar pinch, thumb press, and ball of thumb press. Stepwise multiple linear regression was used to explore the relationship between force type, gender, height, weight, age, and muscle strength. Results: The prediction models developed according to the variable of the strength of the opposite hand are good for explaining variance (76.9–93.1%). Gender is the key demographic variable in the predicting models. Grip strength is not a good predictor of palmar pinch (adjusted-R2: 0.572–0.609), nor of thumb press and ball of thumb (adjusted-R2: 0.279–0.443). Conclusions: We recommend measuring the palmar pinch and ball of thumb strength and using them to predict the other two hand motions for convenience and time saving.

With the increase in awareness about the wide range of issues and adverse effects associated with the use of conventional energy sources came an increase in project management research related to sustainability and sustainable development. Part of that research is devoted to the development of sustainable project typologies that classify projects based on a variety of external factors that can significantly impact these projects. This research focuses on developing a sustainable project typology that classifies sustainable projects based on the external institutional influences. The typology explores the influence of the coercive, normative, and mimetic institutional isomorphisms on the expected level of change, level of uncertainty, project team skills and experience levels, and the level of technology information exchange in sustainable projects. Two case studies are presented to demonstrate the use of the typology to classify sustainable projects based on the external institutional influences.

Twenty married couples with one partner diagnosed as having diabetes at age 40 or older within the past 5 years participated in this study. Participants completed the diabetes or family version of Beliefs About Diabetes (BAD) and the Dyadic Adjustment Scale (DAS). Results showed that perceived barriers to diet and to medication by the person with diabetes were associated with higher marital satisfaction and quality of marriage. In contrast, for the nondiabetic spouse, the perceived benefits of diet were negatively associated with the ability to work with the diabetic spouse. Additional research is needed to better understand the effect of diabetes on the marital relationship.

Abstract Color-kinematics duality in the adjoint has proven key to the relationship between gauge and gravity theory scattering amplitude predictions. In recent work, we demonstrated that at four-point tree-level, a small number of color-dual EFT building blocks could encode all higher-derivative single-trace massless corrections to gauge and gravity theories compatible with adjoint double-copy. One critical aspect was the trivialization of building higher-derivative color-weights — indeed, it is the mixing of kinematics with non-adjoint-type color-weights (like the permutation-invariant d4) which permits description via adjoint double-copy. Here we find that such ideas clarify the predictions of local five-point higher-dimensional operators as well. We demonstrate how a single scalar building block can be combined with color structures to build higher-derivative color factors that generate, through double copy, the amplitudes associated with higher-derivative gauge-theory operators. These may then be suitably mapped, through another double-copy, to higher-derivative corrections in gravity.

A meta-analysis was conducted to determine the association of ethnicity, obesity, and T2D.  Four studies that qualified for inclusion were identified by searching MEDLINE and PubMed databases. The studies on the association of ethnicity and T2D had a combined population resulted in 265,858 study participants. Two studies on the association of obesity and T2D had 197,899 participants. An analysis of the data was conducted utilizing the relative risk ration, odds ratio, and forest plots. The comparison of the relative risk of T2D across ethnic categories by studies range for Blacks was 1.59 to 2.74, Asians was 1.43 to 2.08, and Hispanics .92 to 2.91.  The ethnic difference in the prevalence of diabetes was almost two-fold higher in all ethnic groups than among the Caucasians with a significance level of 95%. A comparison of relative risk of T2D across weight categories was significantly higher among those with a diagnosed of diabetes in all reported areas. The odds ratio was very close to the risk ratio in both ethnicity and obesity to the development of T2D. The meta-analysis findings documented that an association does exist between ethnicity and obesity to the development of type 2 diabetes.</td><td width="0" height="85"> </td></tr><tr><td width="0" height="82"> </td></tr></tbody></table>

Objective: The present study aimed to predict the tendency to Internet Pornography Viewing (IPV) in married men based on difficulty in Emotion Regulation (ER) with the mediating role of impulsivity and experiential avoidance. Methods: The study participants were recruited via advertising banners posted on some of the most popular social networking applications in Iran. A total sample of 123 married men in Isfahan City, Iran, participated in the study. The study participants completed the Pornography Craving Questionnaire (PCQ), the Short-form version of Difficulties in Emotion Regulation Scale (DERS-SF), the Acceptance and Action Questionnaire-II (AAQ-II), and Barratt Impulsiveness Scale (BIS-15) through the internet. The collected data were analyzed in SPSS using descriptive statistics (Mean±SD) and correlation tests. For analyzing the study model, the PLS-SEM technique was performed in WarpPLS. Results: The current research results indicated that difficulties in ER provided a positive direct effect on the tendency to IPV (β=0.37, P<0.01). The results also revealed that impulsivity (β=0.64, P<0.01) and experiential avoidance (β=0.71, P<0.01) played mediating roles between difficulties in ER and the tendency to IPV. The model presented a good fit with the data (AVIF=2.88, GOF=0.63, SPR=1, RSCR=1, SSR=1, NLBCDR=1). Conclusion: Difficulties in ER, impulsivity, and experiential avoidance play important roles in the tendency to IPV. Impulsivity and experiential avoidance, as two modes of ER, can mediate the relationship between difficulties in ER and the tendency to IPV; therefore, they should be taken into consideration in this regard.

Summary Study aim: The objective of this study was to determine differences in body composition status and levels of selected motor components and assess the relationship between selected motor components and body composition in adolescent girls and boys. Material and methods: The study participants were 42 girls and 49 boys from a secondary school in the city of Poznan in Po­land who were participating in the “Active not only online” project. The percentage of body components was evaluated using a bio-impedance method. The modified Eurofit battery of tests was used to assess selected motor components. Results: The prevalence of overweight was higher (12.3%) in boys than girls (2.4%), and girls were more frequently under­weight (16.7%) than boys (6.1%). The results of the study show higher selected motor component levels in girls than in boys when compared to standardized population norms. BMI correlated positively with 20-m shuttle run (r = 0.45, p < 0.05) in girls and with sit and reach (r = 0.30, p < 0.05) in boys, with ‘hand grip’ strength both in girls (r = 0.35, p < 0.05) and boys (r = 0.29, p < 0.05), and was related to percentage of body fat in girls (r = 0.33, p < 0.05) and boys (r = 0.42, p > 0.05).Conclusions: The findings showed that sex and body composition are important factors influencing physical fitness in adoles­cents. We suggest that these factors be considered when designing physical activity interventions.
