    To translate and adapt the Acculturation Rating Scale of Mexican-Americans II (ARSMA-II) for Arab Americans. A multistage translation process followed by a pilot and a large study. The translated and adapted versions, Acculturation Rating Scale for Arabic Americans-II Arabic and English (ARSAA-IIA, ARSAA-IIE), were validated in a sample of 297 Arab Americans. Factor analyses with principal axis factoring extractions and direct oblimin rotations were used to identify the underlying structure of ARSAA-II. Factor analysis confirmed the underlying structure of ARSAA-II and produced two interpretable factors labeled as 'Attraction to American Culture' (AAmC) and 'Attraction to Arabic Culture' (AArC). The Cronbach's alphas of AAmC and AArC were .89 and .85 respectively. Findings support ARSAA-II A & E to assess acculturation among Arab Americans. The emergent factors of ARSAA-II support the theoretical structure of the original ARSMA-II tool and show high internal consistency. PMID:23934518

    Given the paucity of appropriate measures to assess the acculturation patterns of East Asian immigrants in the United States, a new acculturation instrument was developed and evaluated. One-hundred and fifty nonclinical East Asian immigrants (75 males and 75 females) were administered the East Asian Acculturation Measure (EAAM) and provided demographic information concerning length of stay in the United States and gender. Satisfactory reliability is reported for the four acculturation scales: assimilation, separation, integration, and marginalization. Length of stay was not associated with separation but was significantly positively associated with assimilation and integration and significantly negatively associated with marginalization. Gender was not associated with any of the acculturation scales. The findings suggest that the EAAM may be a useful tool for researchers and clinicians to investigate the acculturation patterns of East Asian immigrants. PMID:16228786

    2005-04-01

    This study examined acculturation as represented in dream narratives of 165 Korean immigrant college students living in the USA. A total of 165 dreams were collected and evaluated using the Lee Acculturation Dream Scale, for which locations of dream contents were coded. 39% of the dreams took place in South Korea, while 38% were in the USA. Also, 16% of the dreams included both locations, whereas 7% had no specific dream location. The dreams contained overlapping dream messages, images, scenes, and interactions in both South Korea and the USA. A two-sample t test on the mean scores of the Lee Acculturation Dream Scale indicated no significant difference between men and women. PMID:15941123

    2011-09-01

    The present analysis sought to determine the usefulness and validity of the Short Acculturation Scale for Hispanics (SASH) in assessment of acculturation among Hispanics participating in a colorectal cancer screening study. Primary data was collected from 2008 to 2009 through surveys in East Harlem community-based sites and health clinics among Hispanics. Bivariate correlations and independent samples t tests assessed SASH correlation with acculturation proxies and relationships between proxies, SASH, and sociodemographics. SASH was highly correlated with commonly used acculturation proxies; inter-scale correlations and alpha scores were high. Sociodemographics associated with proxy variables were associated with SASH. In conclusion, SASH is useful and valid for assessing acculturation among Hispanics; however, a shortened version or acculturation proxy variables could also be utilized. PMID:21688089

    Background Culturally valid measures of depression for Spanish-speaking Hispanic women are important for developing and implementing effective interventions to reduce health disparities. The Center for Epidemiological Studies--Depression Scale (CES-D) is a widely used measure of depression. Differential item functioning has been studied using language preference as a proxy for acculturation, but it is unknown if the results were due to acculturation or the language of administration. Objective To evaluate the relationship of acculturation, defined with a dimensional measure, to Spanish CES-D item responses. Method Spanish-speaking Hispanic women (n = 504) were recruited for a randomized controlled trial of Salud, Educación, Prevención y Autocuidado (Health, Education, Prevention and Self-care). Acculturation, an important dimension of variation within the diverse United States Hispanic community, was defined by high or low scores on the Americanism subscale of the Bidimensional Acculturation Scale. Differential item functioning for each of the 20 CES-D items between more acculturated and less acculturated women was tested using ordinal logistic regression. Results No items on the Depressed Affect, Somatic Activity, or Positive Affect subscales showed meaningful differential item functioning, but one item (“People were unfriendly”) on the Interpersonal subscale had small results (R2 = 1.1%). Discussion The majority of CES-D items performed similarly for Spanish-speaking Hispanic women with high and low acculturation. Less acculturated women responded more positively to “People were unfriendly,” despite having an equivalent level of depression, than more acculturated women. Possibilities for improving this item are proposed. PMID:21677596

    2014-01-01

    Newly-arrived African refugees are a vulnerable group of immigrants for whom no validated acculturation measures exist. A valid measurement tool is essential to understand how acculturative processes impact health and health disparities. We adapted the Bicultural Involvement Questionnaire (BIQ) to characterize its reliability among ethnic Somali women residing in Minnesota, and Somali, Somali Bantu, and Burundian women in Arizona. Surveys were administered to 164 adult women. Analyses were conducted along socio-demographic variables of ethnicity, geographic residence, age, and length of time in the United States through t tests and one-way analysis of variance. Exploratory factor analysis was conducted on the modified BIQ. Exploratory factor analyses yielded five subscales: “Speak Native Language”, “Speak English Language”, “Enjoy Native Activities”, “Enjoy American Activities”, and “Desired Ideal Culture”. The subscales of the modified BIQ possessed Cronbach’s α ranging from 0.68 to 0.92, suggestive that all subscales had acceptable to excellent internal consistency. The modified BIQ maintained its psychometric properties across geographic regions of resettled Central and East African refugees. PMID:24573644

    Bulut, Elif; Gayman, Matthew D

    2016-08-01

    This study assesses variations in acculturation experiences by identifying distinct acculturation classes, and investigates the role of these acculturation classes for self-rated mental health among Latino and Asian immigrants in the United States. Using 2002-2003 the National Latino and Asian American Study, Latent Class Analysis is used to capture variations in immigrant classes (recent arrivals, separated, bicultural and assimilated), and OLS regressions are used to assess the link between acculturation classes and self-rated mental health. For both Latinos and Asians, bicultural immigrants reported the best mental health, and separated immigrants and recent arrivals reported the worst mental health. The findings also reveal group differences in acculturation classes, whereby Latino immigrants were more likely to be in the separated class and recent arrivals class relative to Asian immigrants. While there was not a significant group difference in self-rated mental health at the bivariate level, controlling for acculturation classes revealed that Latinos report better self-rated mental health than Asians. Thus, Latino immigrants would actually have better self-rated mental health than their Asian counterparts if they were not more likely to be represented in less acculturated classes (separated class and recent arrivals) and/or as likely to be in the bicultural class as their Asian counterparts. Together the findings underscore the nuanced and complex nature of the acculturation process, highlighting the importance of race differences in this process, and demonstrate the role of acculturation classes for immigrant group differences in self-rated mental health.

    Chinese students are the biggest ethnic group of international students in the United States. This study aims to develop a reliable and valid scale to accurately measure their acculturative stress. A 72-item pool was sent online to Chinese students and a five-factor scale of 32 items was generated by exploratory factor analysis. The five factors included language insufficiency, social isolation, perceived discrimination, academic pressure, and guilt toward family. The Acculturative Stress Scale for Chinese Students demonstrated high reliability and initial validity by predicting depression and life satisfaction. It was the first Chinese scale of acculturative stress developed and validated among a Chinese student sample in the United States. In the future, the scale can be used as a diagnostic tool by mental health professionals and a self-assessment tool by Chinese students. PMID:26280487

    Kosic, Ankica

    2004-09-01

    Using structural equation modeling, this study examines the influences of motivational factors (Need for Cognitive Closure--NCC--and Decisiveness), coping strategies and acculturation strategies on levels of acculturative stress. Two groups of immigrants in Rome (Croatians n= 156 and Poles n= 179) completed a questionnaire that included scales for the various factors. Although our initial hypothesized model was not confirmed, a modified model showed that the motivational factors of NCC and Decisiveness indirectly influence acculturative stress. The modified model with good fit indices indicated that the relationship between NCC and Decisiveness are mediated by coping strategies and acculturation strategies. Specifically, NCC is associated positively with avoidance coping, which in turn is negatively associated with the host group relationships and positively with the original culture maintenance. The last two dimensions predicted lower levels of acculturative stress. Decisiveness was positively associated with the problem-oriented coping and, negatively, with emotional and avoidance coping.

    2015-01-01

    A cross-sectional descriptive study was done using the Acculturation Rating scale of Arab Americans-II, and the Health Promotion and Lifestyle Profile II to assess the relationship between acculturation and health promotion practices among Arab Americans. Findings showed that attraction to American culture was the most important predictor of physical activity; whereas attraction to Arabic culture was the most important predictor of stress management and nutritional practices. Results suggest that, when demographics are controlled, acculturation predicts various health promotion practices in different patterns among members of this group. These findings contribute to a better understanding of acculturation's influence on immigrants' health promotion practices. PMID:26288908

    The current study sought to identify and analyze how Black deaf and hard-of-hearing people conceptualize their deaf and hard-of-hearing identities. That is, what cultural and linguistic factors are involved and how do they interact? An existing measure of Deaf cultural identity, the Deaf Acculturation Scale (DAS), was used to evaluate these questions. Review of the measure's normative sample (n = 3,070) indicated that fewer than 300 self-identified as racial/ethnic minorities (Hispanic/Latino, Black, or Asian). Results of a preliminary study revealed that Non-White deaf individuals responded to DAS items in ways that significantly differed from responses provided by White deaf individuals. Moreover, the existing 5-factor correlated model of the DAS did not fit well with the Non-White group. The current study administered the DAS to a new sample of 106 Black deaf individuals. Principal components analysis determined an appropriate factor structure for this population. In addition to the existing 5 factors, a sixth factor emerged that appears to reflect identity concerns specific to Black deaf people. Ideas for future research, including how to examine the intersections of Deaf identity and racial identity, are discussed. PMID:25967584

    Acculturation, the subsequent changes that occur in one culture after continuous first hand contact with another culture, impacts the dietary habits and health risks of individuals. This study examines the acculturation, dietary habits and anthropometric measurements in a sample of 210 first generation Filipino American immigrants in New Jersey (NJ). Acculturation was measured using the Short Acculturation Scale for Filipino Americans (ASASFA). Dietary acculturation was measured using the Dietary Acculturation Questionnaire for Filipino Americans (DAQFA) and dietary intake was determined using the Block’s Brief Food Frequency Questionnaire (BFFQ). Anthropometric measurements were obtained including weight, height and waist circumference. Acculturation had a significant negative relationship with Filipino Dietary acculturation. Western dietary acculturation was significantly correlated with caloric intake (r(208) = 0.193, p < 0.01), percentage fat intake (r(208) = 0.154, p < 0.05), percentage carbohydrate intake (r(208) = −0.172, p < 0.05), Body Mass Index (BMI) (r(208) = 0.216, p < 0.01) and waist circumference (r(208) = 0.161, p < 0.01). There was no significant correlation between Filipino dietary acculturation, dietary intake and anthropometric measurements. The results showed that Filipino American immigrants have increased risks including increased BMI, waist circumference and increased fat intake. Over all, this research highlighted some dietary changes and their effects on dietary intake and health status. PMID:26703646

    2013-04-01

    We sought to assess the relationship between acculturative type and breastfeeding outcomes among low-income Latinas, utilising a multidimensional assessment of acculturation. We analysed data derived from a breastfeeding peer counselling randomised trial. Acculturation was assessed during pregnancy using a modified Acculturation Rating Scale for Mexican Americans scale. Analyses were restricted to Latinas who completed the acculturation scale and had post-partum breastfeeding data (n = 114). Cox survival analyses were conducted to evaluate differences in breastfeeding continuation and exclusivity by acculturative type. Participants were classified as integrated-high (23.7%, n = 27), traditional Hispanic (36.8%, n = 42), integrated-low (12.3%, n = 14) and assimilated (27.2%, n = 31). The integrated-low group was significantly more likely to continue breastfeeding than the traditional Hispanic, assimilated, and integrated-high groups (P < 0.05, P < 0.05, and P < 0.01, respectively). The traditional Hispanic group was marginally more likely to continue breastfeeding than the integrated-high group (P = 0.06). Breastfeeding continuation rates vary significantly between acculturative types in this multinational, low-income Latina sample. Multidimensional assessments of acculturation may prove useful in better tailoring future breastfeeding promotion interventions. PMID:21787375

    Objective To examine the association between linguistic acculturation (assessed using the Language Use and Linguistic Preference subscales from the Bidimensional Acculturation Scale for Hispanics) and skin cancer-related behaviors among U.S. Hispanic adults. We hypothesized that, compared to Hispanics denoted as Spanish acculturated, English acculturated Hispanics would report less frequent shade seeking and use of sun protective clothing and higher rates of sunscreen use, sunbathing, and indoor tanning. Design Online survey study conducted in September, 2011. Setting Survey of Hispanic adults residing in five southern and western U.S. states. Participants A population-based sample of 788 Hispanic adults drawn from a nationally representative web panel. Main Outcome Measures Self-reported sunscreen use, shade seeking, use of sun protective clothing, sunbathing, and indoor tanning. Results Multivariable regression analyses were conducted to examine predictors of the skin cancer-related behaviors. As hypothesized, English acculturated Hispanics had lower rates of shade seeking and use of sun protective clothing and reported higher rates of sunbathing and indoor tanning than Spanish acculturated Hispanics. English acculturated Hispanics and bicultural Hispanics (i.e., those with high Spanish and high English acculturation) reported comparably high rates of sunbathing and indoor tanning. Results suggested that bicultural Hispanics seek shade and wear sun protective clothing less often than Spanish acculturated Hispanics but more often than English acculturated Hispanics. Acculturation was not associated with sunscreen use. Conclusions Hispanic adults do not routinely engage in behaviors that reduce their risk of skin cancer. Bicultural and English acculturated Hispanics are particularly in need of skin cancer prevention interventions. PMID:23752366

    2009-01-01

    Vietnamese immigrants in the United States face acculturation challenges involving the individual, family, and community. Experts suggest that immigrant family members acculturate at different rates resulting in an acculturation gap, which negatively influences family adjustment. In this study we examined the degree and patterns of acculturation differences between 104 first generation immigrant Vietnamese adolescents and their parents, and whether acculturation gap affected family relationships. Operationalizing the “gap” as both absolute value of differences in acculturation and interactions of parent and adolescent acculturation levels, we examined the impact of such gaps in Vietnamese and American language, identity, and behavioral acculturation on family relationships. Results revealed that family cohesion and satisfaction were predicted by gaps in Vietnamese identity acculturation, but not by gaps in other acculturation domains. PMID:20161537

  10. Scaling metabolic rate fluctuations.

    PubMed

    Labra, Fabio A; Marquet, Pablo A; Bozinovic, Francisco

    2007-06-26

    Complex ecological and economic systems show fluctuations in macroscopic quantities such as exchange rates, size of companies or populations that follow non-Gaussian tent-shaped probability distributions of growth rates with power-law decay, which suggests that fluctuations in complex systems may be governed by universal mechanisms, independent of particular details and idiosyncrasies. We propose here that metabolic rate within individual organisms may be considered as an example of an emergent property of a complex system and test the hypothesis that the probability distribution of fluctuations in the metabolic rate of individuals has a "universal" form regardless of body size or taxonomic affiliation. We examined data from 71 individuals belonging to 25 vertebrate species (birds, mammals, and lizards). We report three main results. First, for all these individuals and species, the distribution of metabolic rate fluctuations follows a tent-shaped distribution with power-law decay. Second, the standard deviation of metabolic rate fluctuations decays as a power-law function of both average metabolic rate and body mass, with exponents -0.352 and -1/4 respectively. Finally, we find that the distributions of metabolic rate fluctuations for different organisms can all be rescaled to a single parent distribution, supporting the existence of general principles underlying the structure and functioning of individual organisms.

  14. Is acculturation related to use of hearing protection?

    PubMed

    Rabinowitz, P M; Duran, R

    2001-01-01

    Noise-exposed employees with limited English skills may pose a special challenge for hearing conservation programs. This pilot field study assessed knowledge, attitudes, and behavior regarding use of hearing protective devices in a largely Hispanic group of 88 workers exposed to industrial noise. Effectiveness of hearing protection was determined through field measurements of personal attenuation ratings. Individual scores on an acculturation scale (first language learned, language at home, degree of literacy in English, preferred language) demonstrated a correlation between a low degree of acculturation and low personal attenuation rating (R2= 0.49, p=0.0001). Low acculturation was also correlated with high-perceived barriers to use of hearing protection (p=0.006). Although neither self reports of self-efficacy nor perceived benefits of hearing protection correlated with personal attenuation rating, perceived barriers to hearing protector use was a significant predictor of hearing protector fit (p=0.05). These results indicate that less acculturated workers may be underutilizing hearing protection in the workplace partly due to perceived barriers to use of hearing protective devices. To be effective, hearing conservation training programs in work sites with an immigrant work force need to address language and cultural barriers to the use of hearing protection. PMID:11669387

  15. Basalt Weathering Rates Across Scales

    Weathering of silicate minerals is a known sink for atmospheric CO2. An estimated 30%-35% of the consumption of CO2 from continental silicate weathering can be attributed to basalt weathering (Dessert et al., 2003). To assess basalt weathering rates we examine weathering advance rates of basalt (w, mm/yr) reported at four scales: denudation rates from basalt watersheds (tens of kilometers), rates of soil formation from soil profiles developed on basaltic parent material of known age (meters), rates of weathering rind formation on basalt clasts (centimeters), and laboratory dissolution rates (millimeters). Basalt weathering advance rates calculated for watersheds range between 0.36 and 9.8x10-3 mm/yr. The weathering advance rate for a basalt soil profile in Hawaii is 8.0x10-3 mm/yr while advance rates for clasts range from 5.6x10-6 to 2.4x10-4 mm/yr. Batch and mixed flow laboratory experiments performed at circum- neutral pH yield advance rates of 2.5x10^{-5} to 3.4x10-7 mm/yr when normalized to BET surface area. These results show increasing advance rates with both increasing scale (from laboratory to watersheds) and increasing temperature. If we assume that basalt weathers at an intrinsic rate that applies to all scales then we conclude that variations in weathering advance rates arise from variations in surface area measurement at different scales (D); therefore, basalt weathering is a fractal system. We measure a fractal dimension (dr) of basalt weathering of 2.2. For Euclidean geometries, measured surface area does not vary with the scale at which it is measured and dr equals 2. For natural surfaces, surface area is related to the scale at which it is measured. As scale increases, the minimum size of the surface irregularities that are measurable also increases. The ratio between BET and geometric normalized laboratory dissolution rates has been defined as a roughness parameter, λ, which ranges from ~10-100. We extend the definition of this roughness parameter

    The Vocational Adaptation Rating Scales (VARS) were developed to provide a comprehensive assessment of maladaptive social behavior related to vocational success, but not directly measuring job performance of mentally retarded workers. Psychometric information derived from the VARS is useful for developing individualized educational plans (IEPs) for compliance with Public Law 94-142; for program, worker or curriculum evaluations; and for predicting placement of workers in vocational training. Research indicates that VARS scores are internally consistent, moderately correlated with other vocational measures, unbiased with respect to sex and age differences, and independent of IQ. Inter-rater reliability is acceptable, and VARS profiles are accurate predictors of level of sheltered workshop placement of mentally retarded workers, independent of IQ, sex and age. Unlike other instruments, the VARS offers a profile of social behavior in a vocational context. PMID:7168570

    This article reports on the associations between acculturation and substance use among 198 ninth-grade Southern California adolescents (mean age = 13.8 years). Substance use measures included 30-day (current) and lifetime use of alcohol and other drugs. Acculturation was measured using the Acculturation, Habits, and Interests Multicultural Scale for Adolescents (AHIMSA) acculturation scale, a multi-dimensional acculturation scale yielding four acculturation strategy scores. Linear regression analyses evaluated the association between acculturation on alcohol and drug use, adjusting for several covariates. Results revealed that the assimilation acculturation strategy was significantly, but negatively associated with current alcohol use, especially among males. The separation acculturation strategy was significantly and positively associated with current alcohol use, especially among females. Marginalization was associated with greater risk for lifetime alcohol and drug use, especially among males, and a greater risk of current drug use among females. The social influence covariates were predictive of both current and lifetime alcohol and drug use. Future studies should incorporate multidimensional acculturation scales in adolescent substance use to understand how different acculturation strategies impact different populations. PMID:17618064

The Multigroup Ethnic Identity Measure and the Acculturation Rating Scale for Mexican Americans-II were completed by the Mexican-American adolescents 7 times over a 3-year period. The findings from longitudinal growth modeling analyses and growth mixture modeling analyses indicate that there is heterogeneity in the initial scores and changes over time on these variables that are related to markers for the cultural qualities of the home environment (i.e., generational status and mother’s most frequent language use). In contrast to expectations, marginalized or assimilated acculturation trajectories/types were not overrepresented in this sample of adolescent offenders. Implications for our understanding of the nature of acculturation and enculturation processes and the way these processes are studied are discussed. PMID:20300539

    Despite the fact that breastfeeding is the most appropriate form of nutrition for the healthy term infant, the rate of initiation in the U.S. is declining. One demographic factor associated with this low rate is ethnicity and so in this study we measured acculturation (one aspect of ethnicity) into the U.S. and its relationship to the successful initiation of breastfeeding in a sample of women recruited approximately 2 months prenatally in a U.S.-Mexico border city. Interviews were administered in English or Spanish by bilingual interviewers prenatally (n = 906), natally (n = 788), and postnatally (n = 715). Acculturation (measured with a 20 item instrument) was strongly related to the intent to (p < 0.001) or the successful initiation of breastfeeding (p < 0.001). Marital status (p = 0.014) and education (p = 0.002) were related to breastfeeding prenatally and natally. Initiation of breastfeeding was highest among those women least acculturated (52.9%) and lowest in those most acculturated (36.1%) indicating an inhibiting effect of acculturation. To improve the rate of initiation of breastfeeding in the U.S. (a national health goal) intervention programs must consider cultural factors. PMID:7722587

    Background Many rating scales have been applied to the evaluation of dystonia, but only few have been assessed for clinimetric properties. The Movement Disorders Society commissioned this task force to critique existing dystonia rating scales and place them in the clinical and clinimetric context. Methods A systematic literature review was conducted to identify rating scales that have either been validated or used in dystonia. Results Thirty six potential scales were identified. Eight were excluded because they did not meet review criteria, leaving twenty-eight scales that were critiqued and rated by the task force. Seven scales were found to meet criteria to be “recommended”: the Blepharospasm Disability Index is recommended for rating blepharospasm; the Cervical Dystonia Impact Scale and the Toronto Western Spasmodic Torticollis Rating Scale for rating cervical dystonia; the Craniocervical Dystonia Questionnaire for blepharospasm and cervical dystonia; the Voice Handicap Index (VHI) and the Vocal Performance Questionnaire (VPQ) for laryngeal dystonia; and the Fahn-Marsden Dystonia Rating Scale for rating generalized dystonia. Two “recommended” scales (VHI and VPQ) are generic scales validated on few patients with laryngeal dystonia, whereas the others are disease-specific scales. Twelve scales met criteria for “suggested” and seven scales met criteria for “listed”. All the scales are individually reviewed in the online appendix. Conclusion The task force recommends five specific dystonia scales and suggests to further validate in dystonia two recommended generic voice-disorder scales. Existing scales for oromandibular, arm and task-specific dystonia should be refined and fully assessed. Scales should be developed for body regions where no scales are available, such as lower limbs and trunk. PMID:23893443

    Introduction Latinas in the United States on average have poorer birth outcomes than Whites, yet considerable heterogeneity exists within Latinas. Puerto Ricans have some of the highest rates of adverse outcomes and are understudied. The goal of this study was to determine if acculturation was associated with adverse birth outcomes in a predominantly Puerto Rican population. Methods We conducted a secondary analysis of Proyecto Buena Salud, a prospective cohort study conducted from 2006 to 2011. A convenience sample of pregnant Latina women were recruited from a tertiary care hospital in Massachusetts. Acculturation was measured in early pregnancy; directly via the Psychological Acculturation Scale, and via proxies of language preference and generation in the United States. Birth outcomes (gestational age and birthweight) were abstracted from medical records (n = 1362). Results After adjustment, psychological acculturation, language preference, and generation was not associated with odds of preterm birth. However, every unit increase in psychological acculturation score was associated with an increase in gestational age of 0.22 weeks (SE = 0.1, p = 0.04) among all births. Women who preferred to speak Spanish (β = −0.39, SE = 0.2, p = 0.02) and who were first generation in the US (β = −0.33, SE = 0.1, p = 0.02) had significantly lower gestational ages than women who preferred English or who were later generation, respectively. Similarly, women who were first generation had babies who weighed 76.11 g less (SE = 35.2, p = 0.03) than women who were later generation. Discussion We observed a small, but statistically significant adverse impact of low acculturation on gestational age and birthweight in this predominantly Puerto Rican population. PMID:26694041

    Acculturation to the culture of the host society as well as to one's heritage culture have been shown to impact immigrants' adjustment during the years following resettlement. While acculturation has been identified as an important factor in adjustment of Vietnamese immigrants (Birman and Tran in Am J Orthopsychiatr 78(1):109-120. doi: 10.1037/0002-9432.78.1.109 , 2008), no clear pattern of findings has emerged and too few studies have employed an ecological approach. The purpose of this paper is to contextualize the study of acculturation and adjustment by taking an ecological approach to exploring these relationships across several life domains, using a bilinear scale, and examining mediators of these relationships for adult Vietnamese refugees (N = 203) in the United States. We call this approach the Ecological Acculturation Framework (EAF). Results of a structural equation model (SEM) showed that job satisfaction fully mediated the relationship between American acculturation and psychological distress, demonstrating that this relationship was specific to an occupational domain. However, while Vietnamese acculturation predicted co-ethnic social support satisfaction, it did not predict reduced psychological distress. Implications for a life domains approach, including domain specificity, are discussed. PMID:26443380

    Although literature provides evidence for the relationship between values and acculturation, the relationship between host community acculturation orientations has not yet been investigated. In this study we tested the effects of four high-order values (openness to change, self-transcendence, conservation, and self-enhancement, devised according to Schwartz's model) on host community acculturation orientations towards immigrants (devised according the interactive acculturation model) in the public domain of employment and the private domain of endogamy/exogamy. Participants were 264 Italian University students, who completed a questionnaire containing the Portrait Values Questionnaire, a measure of personal values, and the Host Community Acculturation Scale, aimed at measuring Italian acculturation strategies towards three groups of immigrants: Immigrants (the general category), Chinese (the valued immigrant group), and Albanians (the devalued immigrant group). Results showed that personal values are related to the adoption of acculturation orientations: In particular, the values that mostly impacted on acculturation orientations were self-transcendence and conservation. Values concerning self-transcendence encourage the adoption of integrationism, integrationism-transformation, and individualism and reduce the adoption of assimilationism, segregationism, and exclusionism. Values concerning conservation encourage the adoption of assimilation, segregation and exclusion orientations and reduce the adoption of both types of integrationism and individualism. Minor effects were found regarding self-enhancement and openness to change. PMID:22044017

    The present study explored the relationship of scores on acculturative stress with those on depression and suicidal ideation among 26 male and 28 female Mexican-American students from a southern California high school. Subjects completed the SAFE acculturative stress scale, the Reynolds Adolescent Depression Scale, and the Suicidal Ideation Questionnaire-Junior. Analyses suggested that acculturating Mexican-American adolescents who report high scores on acculturative stress may report elevated scores for depression and suicidal ideation. Researchers should assess suicide risk within this and other acculturating groups, and risk factors specific to acculturating groups should be considered in the development and implementation of suicide prevention programs in schools.

    Anxiety in pregnancy has been associated with adverse birth outcomes. Relatively few studies have investigated how acculturation affects mental health in pregnancy among Latinas. The goal of this study was to determine if acculturation was associated with anxiety over the course of pregnancy in a sample of predominantly Puerto Rican women. Women were recruited in pregnancy for participation in Proyecto Buena Salud, a prospective cohort study of Latina women (n = 1412). Acculturation was measured via the Psychological Acculturation Scale (PAS), language preference and generation in the USA. Anxiety was measured using the State-Trait Anxiety Instrument. Linear and logistic multivariable regressions were used to investigate associations. After adjustment, women with bicultural identification had significantly lower trait anxiety scores in early pregnancy (β = -3.62, SE = 1.1, p < 0.001) than low acculturated women. Women with higher levels of acculturation as indicated by English-language preference (β = 1.41, SE = 0.7, p = 0.04) and second or third generation in the USA had significantly higher trait anxiety scores in early pregnancy (β = 1.83, SE = 0.6, p < 0.01). Bicultural psychological acculturation was associated with lower trait anxiety in early pregnancy, while English-language preference and higher generation in the USA were associated with higher trait anxiety in early pregnancy.

    Acculturation is a difficult process for minority older adults for a variety of reasons, including access and exposure to mainstream culture, competing ethnic identities, and linguistic ability and preference. There is a paucity of research regarding overall level of acculturation for Chinese older adults in the United States. This study aimed to provide an overall estimate of level of acculturation of Chinese older adults in the United States and to examine correlations between sociodemographic characteristics, self-reported health measures, and level of acculturation. Data were collected through the Population Study of Chinese Elderly in Chicago (PINE) study. This community-based participatory research study surveyed 3,159 Chinese older adults aged 60 and older. The PINE Study Acculturation Scale was used to assess level of acculturation in three dimensions: language preference, media use, and ethnic social relations. Mean acculturation level for all items was 15.3 ± 5.1, indicating low levels of acculturation. Older age, more offspring, lower income, fewer years living in the United States, lower overall health status, and lower quality of life were associated with lower levels of acculturation. Level of acculturation was low in Chinese older adults, and certain subsets of the population were more likely to have a lower level of acculturation. Future research should investigate causality and effects of level of acculturation. PMID:26313023

    A multidimensional bipolar-adjective rating scale is employed as a subjective measure of operator workload in the performance of a one-axis tracking task. The rating scale addressed several dimensions of workload, including cognitive, physical, and perceptual task loading as well as fatigue and stress effects. Eight subjects performed a one-axis tracking task (with six levels of difficulty) and rated these tasks on several workload dimensions. Performance measures were tracking error RMS (root-mean square) and the standard deviation of control stick output. Significant relationships were observed between these performance measures and skill required, task complexity, attention level, task difficulty, task demands, and stress level.

    Vietnamese adult and adolescent immigrants in the United States acculturate to the Western culture at different rates. MostVietnamese parents tend to use the authoritarian parenting method in which dictatorial approaches are enforced, possibly leading to family conflicts and mental health issues. By means of the Suinn-Lew Asian Self-Identity Acculturation Scale, the Parental Authority Questionnaire, the Rosenberg Self-Esteem Scale, and the Reynolds Adolescent Depression Inventory, this exploratory study surveyed 290Vietnamese American adolescents in a major metropolitan area to examine the relationship between their fathers' acculturation levels and parenting styles and the relationships among parenting styles and self-esteem levels and depression scores of the adolescents. Findings revealed that most of the adolescents perceived that their fathers have not acculturated to the U.S. culture and continue to practice the traditional authoritarian parenting style, regardless of the amount of time spent in the United States. Furthermore, results indicate that adolescents who perceived their fathers as using the authoritarian parenting style reported lower levels of self-esteem and higher depression scores when compared with those who perceived their fathers as using the authoritative parenting style.

    Stress represents a prominent aspect of modern life and is associated with numerous negative health consequences. International students are a key force in shaping globalization. However, these students often experience acculturative stress, influencing their health and well-being. The growing number of international students in China emerges as a new global health challenge and presents an opportunity to advance our understanding of acculturative stress. This study aims to investigate the acculturative stress of international students in China, and verify the mechanism and influential factors of acculturative stress. We analyzed survey data from 567 international students attending universities in Wuhan, China. We used a network-based analytical approach to assess the structure of the Acculturative Stress Scale for International Students and used regression analysis to assess the relationships between acculturative stress and theoretically related factors. We found that higher levels of acculturative stress were reported by students from Asia and Africa than from other regions (Europe/America/Oceania). Lower acculturative stress was reported by unmarried students than others and by students well prepared than not well prepared. We verified seven acculturative stress subconstructs: rejection, identity threat, opportunity deprivation, self-confidence, value conflict, cultural competence, and homesickness; and discovered a three-dimensional network structure of these subconstructs. Our results suggest that acculturative stress was more common among international students in China than in developed countries. Acculturative stress was also more common among international students who did not well prepared, married, and belonged to an organized religion. African and Asian students' stress was higher than that for students from other regions. Acculturative stress prevention programs should seek to improve preparedness of the international students for studying abroad and

    2013-01-01

    This article presents an expanded model of acculturation among international migrants and their immediate descendants. Acculturation is proposed as a multidimensional process consisting of the confluence among heritage-cultural and receiving-cultural practices, values, and identifications. The implications of this reconceptualization for the acculturation construct, as well as for its relationship to psychosocial and health outcomes, are discussed. In particular, an expanded operationalization of acculturation is needed to address the “immigrant paradox,” whereby international migrants with more exposure to the receiving cultural context report poorer mental and physical health outcomes. We discuss the role of ethnicity, cultural similarity, and discrimination in the acculturation process, offer an operational definition for context of reception, and call for studies on the role that context of reception plays in the acculturation process. The new perspective on acculturation presented in this article is intended to yield a fuller understanding of complex acculturation processes and their relationships to contextual and individual functioning.

    Most acculturation research throughout the world has been conducted in immigrant settings. In order to examine the generalizability of the previous conclusions in immigrant settings, the present study tried to explore the relationship between cultural identity and self-esteem and the mediating role of acculturation attitudes in China. Using the cross-sectional design, a total number of 342 Uyghur college students were asked to complete a survey comprising the Multi-Group Ethnic/National Identity Measure-Revised Scale, the Acculturation Attitudes Scale, and the Rosenberg Self-Esteem Scale. Using hierarchical multiple regression, the results indicated that cultural identity was positively correlated with self-esteem. A significant mediation of acculturation was observed between cultural identity and self-esteem. These findings demonstrated the significance of cultural identity and acculturation attitudes in the adaptation of Chinese Uyghur college students, in which integration is an optimal acculturation attitude.

    Understanding the processes of acculturation in ethnic minority populations is one of the central tasks of crosscultural research. Addressing challenges of theory, methods, and application in acculturation research requires ongoing advancements in methods and theoretical and model development. The current study was designed to explain a person-centered approach to investigating acculturation and biculturalism and to illustrate this method with a sample of 315 Hispanic youth. Pattern analyses of the Hispanicism and Americanism scores from the Bicultural Involvement Scale yielded four distinct acculturation types, including one characterized by moderate scores on both scales. Relations between acculturation types and indicators of individual, family, and peer adaptation were tested. Results indicated that bicultural youth tended to show the most adaptive pattern of functioning across multiple sociocultural domains. Assimilated youth did not show as strongly negative a pattern as has been reported elsewhere. Implications and benefits of a person-centered approach are discussed. PMID:16799699

    Severity of ciguatera fish poisoning is often quite variable. Two symptom check list rating scales were developed for quantifying illness severity and for selectively monitoring response to therapy in patients with chronic toxicity. Content validity was ascertained, and internal consistency reliability was demonstrated by means of the Cronbach alpha correlation coefficient (alpha = 0.9475). It was concluded that these instruments were valid and reliable, and that they conveniently and accurately recorded illness severity and treatment efficacy. They should prove useful in clinical settings and epidemiologic investigations. PMID:8342175

    The authors reviewed the acculturation literature with the goal of identifying measures used to assess acculturation in Hispanic populations in the context of studies of health knowledge, attitudes, and behavior change. Twenty-six acculturation measures were identified and summarized. As the Hispanic population continues to grow in the United States, there is a need to develop rigorous acculturation measures that include health indicators. Findings suggest that multidimensional acculturation scales are robust measurement tools when assessing nationality, cultural awareness, media and language preferences, and health status. Furthermore, aspects of Hispanic cultural lifestyle, such as beliefs about nutrition and physical activity, affect health care utilization, treatment, and prevention. Health communication researchers should consider aspects of cultural values and beliefs, and their impact on health status, for future research and health promotion interventions. PMID:20582238

    This study examined the influence of the family on adolescents' acculturation, ethnic identity achievement, and psychological functioning. One hundred eighty American-born Asian Indian adolescents and one of their immigrant parents completed questionnaires assessing their acculturation, ethnic identity, and family conflict. Adolescents also completed anxiety and self-esteem measures. The results showed that parents' and adolescents' ratings of their self-identification and ethnic identity were positively associated. Parents who had a separated or marginalized style of acculturation reported higher family conflict than those who had an integrated or assimilated acculturation style. Adolescents reported higher self-esteem, less anxiety, and less family conflict when there was no acculturation gap between them and their parents. The findings suggest that how parents relate to their natal, as well as to the host, culture has direct effects on adolescents' ethnic identity achievement and their psychological functioning.

    An experimental investigation was conducted for the combined purposes of determining the relative merits of various category scales for the prediction of human discomfort response to vibration and for determining the mathematical relationships whereby subjective data are transformed from one scale to other scales. There were 16 category scales analyzed representing various parametric combinations of polarity, that is, unipolar and bipolar, scale type, and number of scalar points. Results indicated that unipolar continuous-type scales containing either seven or nine scalar points provide the greatest reliability and discriminability. Transformations of subjective data between category scales were found to be feasible with unipolar scales of a larger number of scalar points providing the greatest accuracy of transformation. The results contain coefficients for transformation of subjective data between the category scales investigated. A result of particular interest was that the comfort half of a bipolar scale was seldom used by subjects to describe their subjective reaction to vibration.

    2009-07-01

    Although seminal reviews have been published on acculturation and mental health in adults and adolescents, far less is known about how acculturation influences adolescent interpersonal and self-directed violence. This article aims to fill this gap by providing a comprehensive review of research linking acculturation and violence behavior for adolescents of three minority populations: Latino, Asian/Pacific Islander (A/PI), and American Indian/Alaskan Native (AI/AN). The preponderance of evidence from studies on Latino and A/PI youth indicate that higher levels of adolescent assimilation (i.e., measured by time in the United States, English language use, U.S. cultural involvement, or individualism scales) were a risk factor for youth violence. Ethnic group identity or culture-of-origin involvement appear to be cultural assets against youth violence with supporting evidence from studies on A/PI youth; however, more studies are needed on Latino and AI/AN youth. Although some evidence shows low acculturation or cultural marginality to be a risk factor for higher levels of fear, victimization, and being bullied, low acculturation also serves as a protective factor against dating violence victimization for Latino youth. An important emerging trend in both the Latino and, to a lesser extent, A/PI youth literature shows that the impact of acculturation processes on youth aggression and violence can be mediated by family dynamics. The literature on acculturation and self-directed violence is extremely limited and has conflicting results across the examined groups, with high acculturation being a risk factor for Latinos, low acculturation being a risk factor of A/PI youth, and acculturation-related variables being unrelated to suicidal behavior among AI/AN youth. Bicultural skills training as a youth violence and suicide prevention practice is discussed. PMID:19387835

    We examined the relationship between collective self-esteem (i.e., the value one places on being part of a collective group), acculturation, and alcohol-related consequences in a sample of 442 Asian American young adults. We found that membership self-esteem and public collective self-esteem interacted with acculturation such that low levels of both predicted greater rates of consequences. Participants with lower acculturation and greater private collective self-esteem experienced more alcohol consequences. This study suggests that differential aspects of collective self-esteem may serve as protective or risk factors for Asian American young adults depending on degree of acculturation. PMID:23480211

    Acculturation may influence health behaviors, yet mechanisms underlying its effect are not well understood. In this study, we describe relationships between acculturation and health behaviors among low-income housing residents, and examine whether these relationships are mediated by social and contextual factors. Residents of 20 low-income housing sites in the Boston metropolitan area completed surveys that assessed acculturative characteristics, social/contextual factors, and health behaviors. A composite acculturation scale was developed using latent class analysis, resulting in four distinct acculturative groups. Path analysis was used to examine interrelationships between acculturation, health behaviors, and social/contextual factors, specifically self-reported social ties, social support, stress, material hardship, and discrimination. Of the 828 respondents, 69% were born outside of the U.S. Less acculturated groups exhibited healthier dietary practices and were less likely to smoke than more acculturated groups. Acculturation had a direct effect on diet and smoking, but not physical activity. Acculturation also showed an indirect effect on diet through its relationship with material hardship. Our finding that material hardship mediated the relationship between acculturation and diet suggests the need to explicate the significant role of financial resources in interventions seeking to promote healthy diets among low-income immigrant groups. Future research should examine these social and contextual mediators using larger, population-based samples, preferably with longitudinal data. PMID:25462602

    2014-01-01

    The present study used a randomized design, with fully bilingual Hispanic participants from the Miami area, to investigate two sets of research questions. First, we sought to ascertain the extent to which measures of acculturation (heritage and U.S. practices, values, and identifications) satisfied criteria for linguistic measurement equivalence. Second, we sought to examine whether cultural frame switching would emerge – that is, whether latent acculturation mean scores for U.S. acculturation would be higher among participants randomized to complete measures in English, and whether latent acculturation mean scores for Hispanic acculturation would be higher among participants randomized to complete measures in Spanish. A sample of 722 Hispanic students from a Hispanic-serving university participated in the study. Participants were first asked to complete translation tasks to verify that they were fully bilingual. Based on ratings from two independent coders, 574 participants (79.5% of the sample) qualified as fully bilingual and were randomized to complete the acculturation measures in either English or Spanish. Theoretically relevant criterion measures – self-esteem, depressive symptoms, and personal identity – were also administered in the randomized language. Measurement equivalence analyses indicated that all of the acculturation measures – Hispanic and U.S. practices, values, and identifications – met criteria for configural, weak/metric, strong/scalar, and convergent validity equivalence. These findings indicate that data generated using acculturation measures can, at least under some conditions, be combined or compared across languages of administration. Few latent mean differences emerged. These results are discussed in terms of the measurement of acculturation in linguistically diverse populations. PMID:24188146

    Background Mexican-American women exhibit high rates of prenatal maternal depressive symptoms relative to the general population. Though pregnant acculturated Mexican-American women experience cultural stressors such as acculturation, acculturative stress and discrimination that may contribute to elevated depressive symptoms, the contribution of these socio-cultural correlates to depressive symptomology is unknown. Method Ninety-eight pregnant women of Mexican descent were recruited from a community hospital clinic during their first trimester. Women completed surveys about acculturation, acculturative stress, perceived discrimination, general perceived stress, and maternal depressive symptoms as well as the potential protective factor of Mexican cultural values. Results Women who experienced greater acculturative and perceived stress, but not perceived discrimination or acculturation, reported significantly elevated depressive symptoms during pregnancy. Also, women who experienced greater acculturative stress identified with a mixture of Mexican and American cultural values. However, only the Mexican cultural value of respect was protective against maternal depressive symptoms while adhering to the Anglo value of independence and self-reliance was a risk factor. Limitations A limitation in the study is the cross-sectional and descriptive self-report nature of the work, underscoring the need for additional research. Moreover, physiological measures of stress were not analyzed in the current study. Conclusions Results point to acculturative stress, above other cultural stressors, as a potential intervention target in culturally competent obstetric care. These findings have implications for maternal mental health treatment during pregnancy, which likely affects maternal-fetal programming and may favorably affect perinatal outcomes in the vulnerable Mexican-American population.

    The present study used a randomized design, with fully bilingual Hispanic participants from the Miami area, to investigate 2 sets of research questions. First, we sought to ascertain the extent to which measures of acculturation (Hispanic and U.S. practices, values, and identifications) satisfied criteria for linguistic measurement equivalence. Second, we sought to examine whether cultural frame switching would emerge--that is, whether latent acculturation mean scores for U.S. acculturation would be higher among participants randomized to complete measures in English and whether latent acculturation mean scores for Hispanic acculturation would be higher among participants randomized to complete measures in Spanish. A sample of 722 Hispanic students from a Hispanic-serving university participated in the study. Participants were first asked to complete translation tasks to verify that they were fully bilingual. Based on ratings from 2 independent coders, 574 participants (79.5% of the sample) qualified as fully bilingual and were randomized to complete the acculturation measures in either English or Spanish. Theoretically relevant criterion measures--self-esteem, depressive symptoms, and personal identity--were also administered in the randomized language. Measurement equivalence analyses indicated that all of the acculturation measures--Hispanic and U.S. practices, values, and identifications-met criteria for configural, weak/metric, strong/scalar, and convergent validity equivalence. These findings indicate that data generated using acculturation measures can, at least under some conditions, be combined or compared across languages of administration.

    Acculturation has been associated with health-related behaviors in African Americans. We sought to determine if there is a relationship between acculturation and dietary intake in African Americans. African Americans in the PREMIER trial completed the African American Acculturation Scale (AAAS) and 2 nonconsecutive 24-h dietary recalls (n = 238). Analysis of variance (ANOVA) and canonical correlation were used to assess relationships between acculturation and dietary intakes. Canonical correlation (p = 0.05) showed that traditional African Americans had lower intakes of fruits/vegetables and milk/dairy with higher intakes of fats, meat, and nuts. This pattern was supported by differences in the ANOVA. African American acculturation is related to dietary intake. These findings have implications for the design of cancer-related public health messages targeted to African Americans. PMID:16015458

Using data from 427 high school students, factor analysis results distinguished Collective Self-esteem Scale constructs (Luhtanen & Crocker, 1992) from both ethnic identity and outgroup orientation subscales of the Multigroup Ethnic Identity Measure (Phinney, 1992). Subsequent results showed that: 1) both acculturation dimensions were correlated with personal and collective self-esteems, 2) integrationists shared similar levels of personal and collective self-esteems with assimilationists and/or separationists, and 3) marginalizationists generally had the lowest levels of personal and collective self-esteems. Implications are drawn for understanding acculturation among adolescents and for the utility of group-level measures of self-esteem. PMID:17087532

    Objectives. We examined the relationship between acculturation and sun safety among US Latinos. Methods. We used linear regression models to analyze data from 496 Latino respondents to the 2005 Health Information National Trends Survey. Using sunscreen, seeking shade, and wearing protective clothing were the primary outcomes and were assessed by frequency scales. Acculturation was assessed with a composite index. Results. In bivariate models, acculturation was negatively associated with use of shade and protective clothing and positively associated with sunscreen use (all, P < .004). In adjusted models, acculturation was negatively associated with seeking shade and wearing protective clothing across gender and region of residence (all, P < .05). Conclusions. Our results demonstrated both adverse and beneficial effects of acculturation on Latinos’ risk behaviors relating to skin cancer. Education about sun safety is needed for all Latinos and should be tailored to different levels of acculturation. Initiatives for Latinos who are not yet acculturated could focus on reinforcing existing sun-safe behaviors and presenting new ones, such as use of sunscreen; initiatives for highly acculturated Latinos might require more resources because the objective is behavior modification.

    Most research on immigrant acculturation has been conducted with cross-sectional samples, using statistical designs that may not capture different trajectories for the components that contribute to this complex concept. The purpose of this study was to examine change over time in acculturation for 226 women from the former Soviet Union who had lived in the US fewer than eight years when recruited. Using self-report data from four annual waves, growth trajectories were examined in four components of acculturation (American behavior, Russian behavior, English language proficiency, and cultural generativity). Results indicate that these components changed at varying rates. Acculturation is a process with multiple distinct components which should be measured separately to obtain a full profile of change over time. PMID:22180661

    The Modified Cooper-Harper (MCH) scale which is a sensitive indicator of workload in several different types of aircrew tasks was examined. The study determined if variations of the scale might provide greater sensitivity and the reasons for the sensitivity of the scale. The MCH scale and five newly devised scales were examined in two different aircraft simulator experiments in which pilot loading was treated as an independent variable. It is indicated that while one of the new scales may be more sensitive in a given experiment, task dependency is a problem. The MCH scale exhibits consistent senstivity and remains the scale recommended for general use. The MCH scale results are consistent with earlier experiments. The rating scale experiments are reported and the questionnaire results which were directed to obtain a better understanding of the reasons for the relative sensitivity of the MCH scale and its variations are described.

    We demonstrate the robust scale-invariance in the probability density function (PDF) of detrended healthy human heart rate increments, which is preserved not only in a quiescent condition, but also in a dynamic state where the mean level of the heart rate is dramatically changing. This scale-independent and fractal structure is markedly different from the scale-dependent PDF evolution observed in a turbulentlike, cascade heart rate model. These results strongly support the view that a healthy human heart rate is controlled to converge continually to a critical state.

    The primary goal of this study was to examine effects of bicultural efficacy, or perceived confidence in dealing with bicultural acculturation stressors, on type 2 diabetes management and health for first-generation, Cantonese-speaking, Chinese American immigrants (N = 162) recruited for a larger community-based diabetes intervention study (Chesla et al. in Res Nurs Health 36(4):359-372, 2013. doi: 10.1002/nur.21543 ). The current study also tested whether a new Bicultural Efficacy in Health Management (BEFF-HM) scale is a more robust predictor of diabetes and health outcomes than proxy (years in the U.S.) and general acculturation measures. Hierarchical regression analyses of cross-sectional data revealed that high BEFF-HM was significantly related to positive outcomes on five of six diabetes and health measures as hypothesized after accounting for participant characteristics, proxy and general acculturation measures, and social support. Proxy and general acculturation measures failed to predict any study outcome supporting our secondary hypothesis that BEFF-HM is a better predictor of Chinese American immigrants' diabetes and health management. An immigrant-focused research approach advances understanding of acculturation and bicultural efficacy effects on health by identifying key acculturation domains for study. PMID:27412776

    This study examines the impact of level of acculturation and acculturative stress on the mental health of Asian American college students. Hierarchical regression analyses were used to clarify the relation between level of acculturation, acculturative stress, and mental health outcomes (psychological distress and clinical depression). Being less identified with mainstream United States culture was associated with higher psychological distress and clinical depression, but lost significance when acculturative stress was introduced into the model. Retention or relinquishing of identification with one's heritage culture was not associated with mental health outcomes. Although understanding level of acculturation can help us identify those at risk, findings suggest that acculturative stress is a more proximal risk factor and increases risk for mental health problems independently of global perceptions of stress.

    Acculturating to a host country has a negative impact on immigrant women's breastfeeding practices, particularly when coming from countries where breastfeeding rates are higher than Western countries. Whether this is true of those immigrating to the UK remains to be investigated. The study aimed to explore whether acculturating to the UK had detrimental effects on breastfeeding practices of South Asian women, and to provide explanations as to how acculturation may have exerted its influence. Twenty South Asian women completed semi-structured interviews exploring infant feeding experiences. Data were thematically analysed. A bidimensional measure assessed women's acculturation status. Women displaying low acculturation levels were aware of living in a formula-feeding culture but this had little influence on breastfeeding intentions/behaviours; drawing upon South Asian cultural teachings of the psychological benefits of breast milk. These women opted to formula-feed in response to their child's perceived demands or in a bid to resolve conflict; either when receiving information about the best feeding method or between their roles as a mother and daughter-in-law. Highly acculturated women also experienced such conflict; their awareness of the formula-feeding culture governed feeding choice. The findings provide a picture of how acculturation may affect South Asian women's breastfeeding intentions and behaviours; encouraging health service providers to meet the varying needs of an acculturating population. If breastfeeding is to be encouraged, it is necessary to understand factors influencing feeding choice; with particular attention to the acculturation pathways that may govern such decisions. This paper highlights ways to tailor information for South Asian women depending on levels of acculturation. PMID:22136221

    Studies suggest that the process of acculturation for immigrant youth, particularly for second-generation youth, is significantly associated with delinquency and violence. This study explored the acculturation-violence link with respect to acculturative dissonance and ethnic identity. The results revealed in a sample of 329 Chinese, Cambodian, Mien/Laotian, and Vietnamese youth that acculturative dissonance was significantly predictive of serious violence, with full mediation through peer delinquency. Ethnic identity was not significantly associated with peer delinquency or serious violence. Although acculturative dissonance and ethnic identity accounted for a small percentage of variance in violence compared with peer delinquency, it cannot be discounted as trivial. Structural equation analyses provided support for both measurement and structural invariance across the four ethnic groups, lending support for cross-cultural comparisons. The results also lend support for the inclusion of cultural factors in youth violence prevention and intervention efforts. PMID:18229995

    1976-01-01

    The relative merits of various category scales for the prediction of human discomfort response to vibration and the mathematical relationships that allow for transformations of subjective data from one scale to another scale were determined. A total of 16 category scales were studied and these represented various parametric combinations of polarity, scale type, and number of scalar points. Sixteen subject groups were used and each subject group evaluated its comfort/discomfort to vertical sinusoidal vibration using one of the rating scales. The passenger ride quality apparatus which can expose six subjects simultaneously to predetermined vibrations was utilized. The vibration stimuli were composed of repeats of selected sinusoidal frequencies applied at each of nine peak floor acceleration levels. A higher degree of reliability and discriminability was generally obtained from unipolar continuous type scales containing either seven or nine scalar points as opposed to the other scales investigated.

    Asian Americans have lower levels of physical activity (PA) compared to other racial/ethnic groups; however, there is little understanding of the social and cultural determinants of PA in this population. Few analyses describe specific PA domains (occupation-, transportation-, recreation-related), focus on one Asian subgroup, or use validated scales. The study objective was to assess the association between acculturation and activity behaviors (meeting 2008 PA guidelines, activity minutes by PA domain, sitting time) in a cross-sectional sample of urban-dwelling, Chinese American immigrants. Data were from the Chinese American Cardiovascular Health Assessment (CHA CHA) 2010-11 among participants with valid reports of PA minutes, assessed by the WHO Global Physical Activity Questionnaire (n = 1772). Acculturation was assessed using the Stephenson Multigroup Acculturation Scale, a 32-item instrument which characterizes two acculturative dimensions: ethnic society (Chinese) immersion and dominant society (American) immersion (maximum possible scores = 4). Multivariable models regressing activity behaviors on acculturation were run, adjusting for age, sex, household income, education, and age at immigration. Ethnic society immersion was high (mean = 3.64) while dominant society immersion was moderate (mean = 2.23). Higher ethnic society immersion was associated with less recreation-related PA (- 40.7 min/week); higher dominant society immersion was associated with a higher odds of meeting PA guidelines (OR: 1.66 (1.25, 2.20), p < 0.001) and more recreation-related PA (+ 36.5 min/week). Given low PA levels in Chinese adults in China, results suggest that PA for leisure may increase and become a more normative behavior among Chinese American immigrants with acculturation. Understanding acculturation level may inform strategies to increase PA in Chinese Americans. PMID:27570733

The heart rate is regulated by the activity of two branches of the autonomic nervous system: the parasympathetic (PNS) and the sympathetic (SNS) nervous systems. We examine alterations in the scaling property when the balance between PNS and SNS activity is modified, and find that the relative PNS suppression by congestive heart failure results in a substantial increase in the Hurst exponent H towards random-walk scaling 1/f2 and a similar breakdown is observed with relative SNS suppression by primary autonomic failure. These results suggest that 1/f scaling in heart rate requires the intricate balance between the antagonistic activity of PNS and SNS.

    University schools of nursing in Australia are the main providers of nursing education programmes for international students. The large cohort of overseas students requires that universities, as education providers, understand their needs and the problems related to studying and living in Australia. An exploratory descriptive quantitative study was conducted to investigate 119 Chinese international undergraduate nursing students' acculturative stress and sense of coherence at an Australian university in Sydney. Two validated scales were used: Acculturative Stress Scale for International Students (ASSIS) and Sense of Coherence (SOC). Results indicated that overall Chinese nursing students had a moderate level of acculturative stress and sense of coherence. However, there was a significant difference in the level of acculturative stress among three groups of Chinese nursing students enrolled in the Bachelor of Nursing course, and SOC was negatively correlated with the level of acculturative stress. This study extends the knowledge of the experiences of Chinese nursing students studying and living in an English-speaking country. The study also highlights the need for universities to provide relevant support to overseas students to make their study journey smoother and more successful. PMID:21641702

    Knowledge of feeding rates is the basis to understand interaction strength and subsequently the stability of ecosystems and biodiversity. Feeding rates, as all biological rates, depend on consumer and resource body masses and environmental temperature. Despite five decades of research on functional responses as quantitative models of feeding rates, a unifying framework of how they scale with body masses and temperature is still lacking. This is perplexing, considering that the strength of functional responses (i.e. interaction strengths) is crucially important for the stability of simple consumer–resource systems and the persistence, sustainability and biodiversity of complex communities. Here, we present the largest currently available database on functional response parameters and their scaling with body mass and temperature. Moreover, these data are integrated across ecosystems and metabolic types of species. Surprisingly, we found general temperature dependencies that differed from the Arrhenius terms predicted by metabolic models. Additionally, the body-mass-scaling relationships were more complex than expected and differed across ecosystems and metabolic types. At local scales (taxonomically narrow groups of consumer–resource pairs), we found hump-shaped deviations from the temperature and body-mass-scaling relationships. Despite the complexity of our results, these body-mass- and temperature-scaling models remain useful as a mechanistic basis for predicting the consequences of warming for interaction strengths, population dynamics and network stability across communities differing in their size structure.

  7. Critical scaling with strain rate in overdamped sheared disordered solids

    Clemmer, Joel; Salerno, Kenneth; Robbins, Mark

    In the limit of quasistatic shear, disordered solids demonstrate non-equilibrium critical behavior including power-law distributions of avalanches. Using molecular dynamics simulations of 2D and 3D overdamped binary LJ glasses, we explore the critical behavior in the limit of finite strain rate. We use finite-size scaling to find the critical exponents characterizing shear stress, kinetic energy, and measures of temporal and spatial correlations. The shear stress of the system rises as a power β of the strain rate. Larger system size extends this power law to lower rates. This behavior is governed by a power law drop of the dynamic correlation length with increasing shear stress defined by the exponent ν. This finite-size effect also impacts the scaling of the RMS kinetic energy with strain rate as avalanches begin nucleating simultaneously leading to continuous deformation of the solid. As system size increases, avalanches begin overlapping at lower rates. The correlation function of non-affine displacement exhibits novel anisotropic power law scaling with the magnitude of the wave vector. Its strain rate dependence is used to determine the scaling of the dynamic correlation length. Support provided by: DMR-1006805; NSF IGERT-0801471; OCI-0963185; CMMI-0923018.

    Background Incidence rates for breast cancer are higher among Mexican-American (MA) women in the United States than women living in Mexico. Studies have shown higher prevalence of breast cancer risk factors in more acculturated than less acculturated Hispanic/Latinas in the United States. We compared the prevalence of behavioral risk factors and family history of breast cancer by level of acculturation and country of residence in women of Mexican descent. Methods Data were collected from 1,201 newly diagnosed breast cancer patients living in Mexico (n = 581) and MAs in the United States (n = 620). MA participants were categorized into three acculturation groups (Spanish dominant, bilingual, and English dominant); women living in Mexico were used as the referent group. The prevalence of behavioral risk factors and family history of breast cancer were assessed according to acculturation level, adjusting for age at diagnosis and education. Results In the adjusted models, bilingual and English-dominant MAs were significantly more likely to have a body mass index of 30 kg/m2 or greater, consume more than one alcoholic beverage a week, and report having a family history of breast cancer than women living in Mexico. All three U.S. acculturation groups were significantly more likely to have lower total energy expenditure (≤533 kcal/d) than women in Mexico. English-dominant women were significantly less likely to ever smoke cigarettes than the Mexican group. Conclusions Our findings add to the limited scientific literature on the relationships among acculturation, health behavior, and family history of breast cancer in Mexican and MA women.

    Transport in porous media is quite complex, and still yields occasional surprises. In geological porous media, the rate at which chemical reactions (e.g., weathering and dissolution) occur is found to diminish by orders of magnitude with increasing time or distance. The temporal rates of laboratory experiments and field observations differ, and extrapolating from laboratory experiments (in months) to field rates (in millions of years) can lead to order-of-magnitude errors. The reactions are transport-limited, but characterizing them using standard solute transport expressions can yield results in agreement with experiment only if spurious assumptions and parameters are introduced. We previously developed a theory of non-reactive solute transport based on applying critical path analysis to the cluster statistics of percolation. The fractal structure of the clusters can be used to generate solute distributions in both time and space. Solute velocities calculated from the temporal evolution of that distribution have the same time dependence as reaction-rate scaling in a wide range of field studies and laboratory experiments, covering some 10 decades in time. The present theory thus both explains a wide range of experiments, and also predicts changes in the scaling behavior in individual systems with increasing time and/or length scales. No other theory captures these variations in scaling by invoking a single physical mechanism. Because the successfully predicted chemical reactions include known results for silicate weathering rates, our theory provides a framework for understanding changes in the global carbon cycle, including its effects on extinctions, climate change, soil production, and denudation rates. It further provides a basis for understanding the fundamental time scales of hydrology and shallow geochemistry, as well as the basis of industrial agriculture. PMID:26232976

    2009-03-01

    Portuguese immigrants to North America represent a large ethnic group with unique family therapy needs. The present study investigates acculturation and the family lives of Portuguese (Azorean) immigrants in Canada. Methods of analytic induction and constant comparison from grounded theory were used to examine transcripts of interviews with 21 Azorean immigrant women and 28 Azorean immigrant men. A model emerged wherein (a) immigration and acculturation act as stressors on the family unit, as described by the categories Process of Change and Family Relationships; (b) family members adopt generation- and gender-specific acculturative strategies, as illustrated by the categories Duas Culturas (Two Cultures) and Falando Portuges (Speaking Portuguese); and (c) as family members acculturate, discords arise and are resolved according to the cultural traits different members have adopted. The categories Discord Resolution and Preocupação (Preoccupations) illustrate this last dynamic. Implications for family therapy with immigrant families include an indication for community-level interventions, emphasis on confidentiality, awareness of acculturation stress and different acculturative strategies within the family, and aiding the family in the negotiation and integration of a new bicultural reality.

  3. Rate-dependent scaling laws for spall failure

    NASA Astrophysics Data System (ADS)

    Wilkerson, Justin; Ramesh, Kt

    Here we derive simple bounds on the growth rate of voids considering the combined retarding effects of micro-inertia and dislocation kinetics. We make use of these bounds to derive simple scaling laws capable of predicting the strong rate-dependence of spall strength. We show that the rate-sensitivity exponent for spall strength is bounded to below 6/7 when micro-inertia is the dominant retarding effect on void growth. However, under conditions in which the void growth is predominately governed by dislocation kinetics the rate-sensitivity exponent may rise to a maximum value of 1. With these scaling laws in hand, we go on to further explore the role of microstructure on spall strength. Though simple, the derived scaling laws compare well with experimental measurements and prove useful in shedding light on some of the more perplexing observations associated with spall failure. In particular, the scaling laws are helpful in understanding the somewhat anomalous dependence of spall strength on pre-existing microstructure, e.g. grain size and purity content.

    2007-01-01

    We propose a novel technique for heart rate detection on a subject that stands on a common electronic weighing scale. The detection relies on sensing force variations related to the blood acceleration in the aorta, works even if wearing footwear, and does not require any sensors attached to the body. We have applied our method to three different weighing scales, and estimated whether their sensitivity and frequency response suited heart rate detection. Scale sensitivities were from 490 nV/V/N to 1670 nV/V/N, all had an underdamped transient response and their dynamic gain error was below 19% at 10 Hz, which are acceptable values for heart rate estimation. We also designed a pulse detection system based on off-the-shelf integrated circuits, whose gain was about 70x10(3) and able to sense force variations about 240 mN. The signal-to-noise ratio (SNR) of the main peaks of the pulse signal detected was higher than 48 dB, which is large enough to estimate the heart rate by simple signal processing methods. To validate the method, the ECG and the force signal were simultaneously recorded on 12 volunteers. The maximal error obtained from heart rates determined from these two signals was +/-0.6 beats/minute. PMID:18003457

    The increasing number of crimes in areas with large concentrations of people have made cities one of the main sources of violence. Understanding characteristics of how crime rate expands and its relations with the cities size goes beyond an academic question, being a central issue for contemporary society. Here, we characterize and analyze quantitative aspects of murders in the period from 1980 to 2009 in Brazilian cities. We find that the distribution of the annual, biannual and triannual logarithmic homicide growth rates exhibit the same functional form for distinct scales, that is, a scale invariant behavior. We also identify asymptotic power-law decay relations between the standard deviations of these three growth rates and the initial size. Further, we discuss similarities with complex organizations.

    Asians and Pacific Islanders (API) are among the fastest growing minority groups within the United States, and this growth has been accompanied by an increase in HIV incidence. Between, 2000 and 2010, the API HIV infection rate increased from 4.5% to 8.7%; however, there is a paucity of HIV-related research for this group, and even less is known about the prevalence and correlates of antiretroviral therapy adherence behavior, quality of life, impact of stress, and efficacious self-management among HIV+ API Americans. This paper examines how acculturation and perceived stress affect depression symptomatology and treatment seeking in the HIV+ API population. A series of cross-sectional audio computer-assisted self-interviews (ACASI) were conducted with a convenience sample of 50 HIV+ API (29 in San Francisco and 21 in New York City). The relationship between acculturation and perceived stress was analyzed, and the results indicate that for those HIV+ API who reported low or moderate acculturation (as compared to those who reported high acculturation), stress was significantly mediated by depression symptomology. Interventions to address acculturation and reduce perceived stress among API generally and Asians specifically are therefore needed. PMID:25059642

  11. Variation of foraging rate and wing loading, but not resting metabolic rate scaling, of insect pollinators

    NASA Astrophysics Data System (ADS)

    Terblanche, John S.; Anderson, Bruce

    2010-08-01

    Morphological, physiological and behavioural variation with body size (i.e. scaling) may affect costs of living in a particular environment for insects and, ultimately, pollination or foraging success. However, few studies have directly assessed the scaling of these traits at the species level. Using two similar-sized pollinator species (the hawkmoth Macroglossum trochilus and the fly Moegistorhynchus longirostrus), we compare intraspecific scaling relationships of resting metabolic rate (RMR), foraging rate (FR) and wing loading (WL) to address this paucity of data. Scaling of RMR was similar for both taxa although the intercepts for the relationships differed. However, these two species showed variation in WL scaling relationships and fundamentally different FR scaling. For M. longirostrus, FR scaling was positive but non-significantly related to body mass while for M. trochilus FR scaling was negative. This suggests that variation in FR and WL, but not RMR scaling, among these flies and hawkmoths may impose significant energetic costs which could affect animal-plant interactions in the wild.

    2010-01-01

    This article presents an expanded model of acculturation among international migrants and their immediate descendants. Acculturation is proposed as a multidimensional process consisting of the confluence among heritage-cultural and receiving-cultural practices, values, and identifications. The implications of this reconceptualization for the acculturation construct, as well as for its relationship to psychosocial and health outcomes, are discussed. In particular, an expanded operationalization of acculturation is needed to address the "immigrant paradox," whereby international migrants with more exposure to the receiving cultural context report poorer mental and physical health outcomes. We discuss the role of ethnicity, cultural similarity, and discrimination in the acculturation process, offer an operational definition for context of reception, and call for studies on the role that context of reception plays in the acculturation process. The new perspective on acculturation presented in this article is intended to yield a fuller understanding of complex acculturation processes and their relationships to contextual and individual functioning.

    The purpose of this cross-sectional pilot study was to examine associations between food insecurity, acculturation, demographic factors, and children's fruit and vegetable intake among a sample of Hispanic children ages 5 to 12 years. A convenience sample of 184 parents of low socioeconomic status completed one-time, self-administered questionnaires assessing demographic information, acculturation, and food insecurity in the spring of 2006. In addition, children's fruit and vegetable intake at home was measured using a validated seven-item index. Parents were recruited through local elementary schools in San Antonio, TX. Pearson and Spearman correlations were used to examine the associations between the variables. t tests were used to explore the differences in means of children's fruit and vegetable intake at home for acculturation and food insecurity levels. Statistical significance was set at P<0.05. Significant correlations were found between demographic variables, acculturation, food insecurity, and children's fruit and vegetable intake at home. The overall mean fruit and vegetable intake at home was 1.04+/-0.63 (mean+/-standard deviation) servings per day. Higher rates of acculturation and higher rates of food insecurity were associated with lower fruit and vegetable intake at home. The findings reported in this study suggest a need for culturally tailored interventions targeting Hispanic children because fruit and vegetable intake at home among Hispanic children was low, regardless of the level of acculturation or food insecurity.

    The commonly used rating scales for negative symptoms in schizophrenia have shown good reliability, but disagreement persists regarding both the content definition and the validity of several items. Instead, authors have recommended rating the specific behaviors that are defined as negative symptoms. To surmount these shortcomings, we developed a new rating scale for negative symptoms: the Motor-Affective-Social Scale (MASS). During a 5-minute structured interview, hand coverbal gestures, spontaneous smiles, voluntary smiling, and questions asked by the interviewer were counted and rated on 101 inpatients with a diagnosis of schizophrenia or schizoaffective disorder. Information on social behavior was obtained from nursing staff. The scale consisted of a total of eight items. The MASS showed high internal consistency (Cronbach alpha coefficient=0.81), inter-rater reliability, and test-retest reliability (intra-class correlation coefficient=0.81). Convergent validity analyses showed high correlations between MASS scores and scores on the Scale for the Assessment of Negative Symptom (SANS), and the negative symptoms subscale of the Positive and Negative Syndrome Scale (PANSS). The MASS showed excellent psychometric properties, practicality, and subject tolerability. Future research that includes the use of the MASS with other patient populations and that investigates the scale's sensitivity during clinical trials should be performed. PMID:18722021

Scaling predictions derived from the new model (termed LSD) suggest two potential sources of bias in the previous models: different energy responses of the secondary neutron detectors used in developing the models, and different geomagnetic parameterizations. In addition, the particle flux spectra generated by the LSD model allow one to generate nuclide-specific scaling factors that reflect the influences of the flux energy distribution and the relevant excitation functions (probability of nuclide production in a given nuclear reaction as a function of energy). Resulting scaling factors indicate 3He shows the strongest positive deviation from the flux-based scaling, while 14C exhibits a negative deviation. These results are consistent with previous studies showing an increasing 3He/10Be ratio with altitude in the Himalayas, but with a much lower magnitude for the effect. Furthermore, the new model provides a flexible framework for exploring the implications of future advances in model inputs. For example, the effects of recently updated paleomagnetic models (e.g. Korte et al., 2011, Earth and Planet Sci. Lett. 312, 497-505) on scaling predictions will also be presented.

  2. Reliability and validity of the Wolfram Unified Rating Scale (WURS)

    2012-01-01

    Background Wolfram syndrome (WFS) is a rare, neurodegenerative disease that typically presents with childhood onset insulin dependent diabetes mellitus, followed by optic atrophy, diabetes insipidus, deafness, and neurological and psychiatric dysfunction. There is no cure for the disease, but recent advances in research have improved understanding of the disease course. Measuring disease severity and progression with reliable and validated tools is a prerequisite for clinical trials of any new intervention for neurodegenerative conditions. To this end, we developed the Wolfram Unified Rating Scale (WURS) to measure the severity and individual variability of WFS symptoms. The aim of this study is to develop and test the reliability and validity of the Wolfram Unified Rating Scale (WURS). Methods A rating scale of disease severity in WFS was developed by modifying a standardized assessment for another neurodegenerative condition (Batten disease). WFS experts scored the representativeness of WURS items for the disease. The WURS was administered to 13 individuals with WFS (6-25 years of age). Motor, balance, mood and quality of life were also evaluated with standard instruments. Inter-rater reliability, internal consistency reliability, concurrent, predictive and content validity of the WURS were calculated. Results The WURS had high inter-rater reliability (ICCs>.93), moderate to high internal consistency reliability (Cronbach’s α = 0.78-0.91) and demonstrated good concurrent and predictive validity. There were significant correlations between the WURS Physical Assessment and motor and balance tests (rs>.67, p<.03), between the WURS Behavioral Scale and reports of mood and behavior (rs>.76, p<.04) and between WURS Total scores and quality of life (rs=-.86, p=.001). The WURS demonstrated acceptable content validity (Scale-Content Validity Index=0.83). Conclusions These preliminary findings demonstrate that the WURS has acceptable reliability and validity and

    As a way of employing the flamelet approach, which was developed essentially for incompressible flows, to model supersonic combustion, the role ascribed to pressure has not been very convincing. That is, the reaction rate is often scaled on the square of the pressure in the finite Mach number flow field relative to the usually atmospheric static pressure field used in the generation of the flamelet library. This scaling assumption is quite simple and will therefore be very attractive if it has a sound theoretical basis and it works for a large selection of high-speed combustion flows. We try to find some justifications for different scaling laws, with the hope of coming up with a more universally-acceptable flamelet procedure for supersonic combustion.

    Previous studies on heart rate variability (HRV) using chaos theory, fractal scaling analysis, and many other methods, while fruitful in many aspects, have produced much confusion in the literature. Especially the issue of whether normal HRV is chaotic or stochastic remains highly controversial. Here, we employ a new multiscale complexity measure, the scale-dependent Lyapunov exponent (SDLE), to characterize HRV. SDLE has been shown to readily characterize major models of complex time series including deterministic chaos, noisy chaos, stochastic oscillations, random 1/f processes, random Levy processes, and complex time series with multiple scaling behaviors. Here we use SDLE to characterize the relative importance of nonlinear, chaotic, and stochastic dynamics in HRV of healthy, congestive heart failure, and atrial fibrillation subjects. We show that while HRV data of all these three types are mostly stochastic, the stochasticity is different among the three groups.

    Adherence to medication is an important predictor of illness course and outcome in psychosis. The Medication Adherence Rating Scale (MARS) is a ten-item self-report measure of medication adherence in psychosis [Thompson, K., Kulkarni, J., Sergejew, A.A., 2000. Reliability and validity of a new Medication Adherence Rating Scale (MARS) for the psychoses. Schizophrenia Research. 42. 241-247]. Although initial results suggested that the scale has good reliability and validity, the development sample was small. The current study aimed to establish the psychometric properties of the MARS in a sample over four times larger. The scale was administered to 277 individuals with psychosis, along with measures of insight and psychopathology. Medication adherence was independently rated by each individual's keyworker. Results showed the internal consistency of the MARS to be lower than in the original sample, though adequate. MARS total score correlated weakly with keyworker-rated adherence, hence concurrent validity of the scale appeared only moderate to weak. The three factor structure of the MARS was replicated. Examination of the factor scores suggested that the factor 1 total score, which corresponds to the Medication Adherence Questionnaire [Morisky,D.E., Green,L.W. and Levine,D.M., 1986. Concurrent and predictive validity of a self-reported measure of medication adherence. Medical Care. 24, 67-74] may be a preferable measure of medication adherence behaviour to the total scale score.

    We present three linkage-disequilibrium (LD)-based recombination maps generated using whole-genome sequence data from 10 Nigerian chimpanzees, 13 bonobos, and 15 western gorillas, collected as part of the Great Ape Genome Project (Prado-Martinez J, et al. 2013. Great ape genetic diversity and population history. Nature 499:471-475). We also identified species-specific recombination hotspots in each group using a modified LDhot framework, which greatly improves statistical power to detect hotspots at varying strengths. We show that fewer hotspots are shared among chimpanzee subspecies than within human populations, further narrowing the time scale of complete hotspot turnover. Further, using species-specific PRDM9 sequences to predict potential binding sites (PBS), we show higher predicted PRDM9 binding in recombination hotspots as compared to matched cold spot regions in multiple great ape species, including at least one chimpanzee subspecies. We found that correlations between broad-scale recombination rates decline more rapidly than nucleotide divergence between species. We also compared the skew of recombination rates at centromeres and telomeres between species and show a skew from chromosome means extending as far as 10-15 Mb from chromosome ends. Further, we examined broad-scale recombination rate changes near a translocation in gorillas and found minimal differences as compared to other great ape species perhaps because the coordinates relative to the chromosome ends were unaffected. Finally, on the basis of multiple linear regression analysis, we found that various correlates of recombination rate persist throughout the African great apes including repeats, diversity, and divergence. Our study is the first to analyze within- and between-species genome-wide recombination rate variation in several close relatives. PMID:26671457

    Objective To assess the relationship between parental acculturation and infant feeding style in a sample of Latino parents. Design and Methods A post-hoc analysis was performed using data from an ongoing four-site RCT to promote early childhood obesity prevention. Cross-sectional data of parent-child dyads at the 12 month well-child visit who self-reported their Latino ethnicity were analyzed. The Short Acculturation Scale for Hispanics (SASH) and a subset of the Infant Feeding Style Questionnaire (IFSQ) that assessed four primary feeding styles were administered. Analyses compared SASH level (low v. high) with each feeding style. Results Complete SASH data was available for 398 of 431 Latino dyads. Median SASH score was 1.8 (IQR 1.4 – 2.7); 82% of participants had low acculturation (score < 3). Of the nine outcome variables, four were significantly associated with SASH: “Laissez-Faire/attention” (AOR 2.3 [95% CI 1.06 – 5.13], p=0.004), “Laissez-Faire/diet quality” (3.9 [1.7 – 8.75], p=0.005), “Pressuring as soothing” (3.6 [1.63 – 8.05], p=0.007) and “Restrictive/diet quality” (0.4 [0.19 – 0.94], p=0.031). Conclusions Latino parents with lower acculturation were more likely than those with higher acculturation to endorse feeding styles that are associated with child obesity. Further research is needed to determine why acculturation and feeding style relate. PMID:25755135

    Scales were developed to measure affective aspects of Latino, American, and global-human identities among first- and second-generation Mexican-American adolescents. Participants were 84 boys and 93 girls from the Los Angeles high schools. 60 were born in Mexico, and 117 were born in the United States and had at least one parent born in Mexico. The affective Latino and American measures were independent and predictably related to a behaviorally oriented measure of acculturation. They were also used to identify Berry's four modes of acculturation: Separated, Assimilated, Marginalized, and Bicultural. The four acculturation groups rated similarly on self-esteem and academic aspiration. The first and second generations each scored higher on Latino identity than on American identity. PMID:9198403

    Determination of the frictional properties of rocks is crucial for an understanding of earthquake mechanics, because most earthquakes are caused by frictional sliding along faults. Prior studies using rotary shear apparatus revealed a marked decrease in frictional strength, which can cause a large stress drop and strong shaking, with increasing slip rate and increasing work rate. (The mechanical work rate per unit area equals the product of the shear stress and the slip rate.) However, those important findings were obtained in experiments using rock specimens with dimensions of only several centimetres, which are much smaller than the dimensions of a natural fault (of the order of 1,000 metres). Here we use a large-scale biaxial friction apparatus with metre-sized rock specimens to investigate scale-dependent rock friction. The experiments show that rock friction in metre-sized rock specimens starts to decrease at a work rate that is one order of magnitude smaller than that in centimetre-sized rock specimens. Mechanical, visual and material observations suggest that slip-evolved stress heterogeneity on the fault accounts for the difference. On the basis of these observations, we propose that stress-concentrated areas exist in which frictional slip produces more wear materials (gouge) than in areas outside, resulting in further stress concentrations at these areas. Shear stress on the fault is primarily sustained by stress-concentrated areas that undergo a high work rate, so those areas should weaken rapidly and cause the macroscopic frictional strength to decrease abruptly. To verify this idea, we conducted numerical simulations assuming that local friction follows the frictional properties observed on centimetre-sized rock specimens. The simulations reproduced the macroscopic frictional properties observed on the metre-sized rock specimens. Given that localized stress concentrations commonly occur naturally, our results suggest that a natural fault may lose its

    Our understanding of temperature dissipation rate χ within the upper ocean boundary layer, which is critical for climate forecasts, is very limited. Near-surface turbulence also affects dispersion of contaminants and biogeochemical tracers. Using high-resolution optical turbulence measurements, scaling laws for χ are investigated under forcing states where either the daytime heat flux or the wind stress forcing is dominant. We find that χ remains constant over 1.5 times the significant wave height, while over a layer below, χ decays based on the local surface forcing. When the heat flux is dominant, traditional scaling based on the Monin-Obukhov similarity theory remains valid; χ ∝ z-1. When the wind stress dominates, we observe the emergence of a new scaling, χ ∝ z-1/2, which is explained by invoking the effect of small-scale coherent structures on vertical heat transport. These results have implications for improved modeling of the ocean's heat and CO2 intake.

    This study investigates the relationship between level of acculturation and acculturation stress, and the extent to which each predicts problems related to drinking. Hispanics who met criteria for hazardous drinking completed measures of acculturation, acculturation stress, and drinking problems. Sequential multiple regression was used to determine whether levels of self-reported acculturation stress predicted concurrent alcohol problems after controlling for the predictive value of acculturation level. Acculturation stress accounted for significant variance in drinking problems while adjusting for acculturation, income, and education. Choosing to drink in response to acculturation stress should be an intervention target with Hispanic heavy drinkers. PMID:24215224

    Background Determinants of physical activity in minority populations remain under-explored. Acculturation is one proposed mechanism for the disparities that exist between racial and ethnic groups in health outcomes. Methods This cross-sectional study evaluated the relation of language acculturation and generation in the US since migration with leisure-time and occupational activity. A low-income, multiethnic urban population was recruited from Massachusetts small businesses (SB) (n = 1725) and health centers (HC) (n = 2205). Baseline data were collected between May 2000 and February 2002. Results Individuals with low acculturation reported leisure-time activity 3–5 MET hours/week lower than those who were highly acculturated (P < 0.05). Generation predicted leisure-time activity only in SB participants. In the HC, least acculturated participants reported occupational activity 10–12 MET hours/week higher than highly acculturated participants. In SB men, acculturation was inversely associated with occupational activity; in SB women, language acculturation was positively associated with occupational activity. Generation was not predictive of occupational activity. Conclusion Language acculturation and generation were positively associated with leisure-time activity. Language acculturation is also associated with occupational activity. Acculturation is important to consider when designing public health interventions. PMID:16481031

    Refugee adolescents often immigrate to a new society because of experiences of persecution and trauma, which can have profound effects on their mental health. Once they immigrate, many refugees experience stressors related to resettlement and acculturation in the new society. The current study examined relationships among acculturation styles and hassles and the well-being of young refugees as well as the role of gender. Data were collected from 135 young refugees (M age = 15.39, SD = 2.2; 62 % male) from Somalia resettled in the United States The findings from our study indicate that in addition to trauma history, acculturative hassles and acculturation style impact the wellbeing of Somali refugee adolescents. These findings indicate the need to understand both past experiences as well as current challenges. Potential areas for intervention are discussed. PMID:26048358

    Previous studies reported mixed findings on the relationship between acculturation and health status among Asian Americans due to different types of acculturation measures used or different Asian subgroups involved in various studies. We aim to fill the gap by applying multiple measures of acculturation in a diverse sample of Asian subgroups. A cross sectional study was conducted among Chinese, Korean and Vietnamese Americans in Washington D.C. Metropolitan Area to examine the association between health status and acculturation using multiple measures including the Suinn-Lew Asian Self-Identity Acculturation (SL-ASIA) scale, clusters based on responses to SL-ASIA, language preference, length of stay, age at arrival in the United Sates and self-identity. Three clusters (Asian (31%); Bicultural (47%); and American (22%)) were created by using a two-step hierarchical method and Bayesian Information Criterion values. Across all the measures, more acculturated individuals were significantly more likely to report good health than those who were less acculturated after adjusting for covariates. Specifically, those in the American cluster were 3.8 times (95% Confidence Interval (CI): 2.2, 6.6) more likely and those in the Bicultural cluster were 1.7 times more likely (95% CI: 1.1, 2.4) to report good health as compared to those in the Asian cluster. When the conventional standardized SL-ASIA summary score (range: −1.4 to 1.4) was used, a one point increase was associated with 2.2 times greater odds of reporting good health (95% CI: 1.5, 3.2). However, the interpretation may be challenging due to uncertainty surrounding the meaning of a one point increase in SL-ASIA summary score. Among all the measures used, acculturation clusters better approximated the acculturation process and provided us with a more accurate test of the association in the population. Variables included in this measure were more relevant for our study sample and may have worked together to capture the

  18. Escape Rates in a Stochastic Environment with Multiple Scales

    Forgoston, Eric; Schwartz, Ira B.

    2009-01-01

    We consider a stochastic environment with two time scales and outline a general theory that compares two methods to reduce the dimension of the original system. The first method involves the computation of the underlying deterministic center manifold followed by a naive replacement of the stochastic term. The second method allows one to more accurately describe the stochastic effects and involves the derivation of a normal form coordinate transform that is used to find the stochastic center manifold. The results of both methods are used along with the path integral formalism of large fluctuation theory to predict the escape rate from one basin of attraction to another. The general theory is applied to the example of a surface flow described by a generic, singularly perturbed, damped, nonlinear oscillator with additive, Gaussian noise. We show how both nonlinear reduction methods compare in escape rate scaling. Additionally, the center manifolds are shown to predict high prehistory probability regions of escape. The theoretical results are confirmed using numerical computation of the mean escape time and escape prehistory, and we briefly discuss the extension of the theory to stochastic control.

    We examined the association between postnatal depression (PND), acculturation and mother-infant bond among 38 Eritrean asylum seekers in Israel, who were within 6 months of delivery. Participants completed a survey in their native language. A high rate of women (81.6 %) met the clinical threshold for PND on the Edinburgh Postnatal Depression Scale. Higher severity of PND (partial r = -.64, p < .001), higher identification with Israeli culture (partial r = -.45, p = .02), and lower quality of romantic relationship were associated with impaired mother-infant bond (partial r = .58, p = .002). Findings highlight the need to establish services to screen and treat PND among this vulnerable population in the receiving countries. PMID:26864379

    Chromatography is an essential downstream processing step in the production of biopharmaceuticals. Here we present an approach to chromatography scale-up using scale-down experimentation integrated with general rate modelling. This type of modelling takes account all contributions to the mass transfer kinetics providing process understanding. The model is calibrated using a 2.5 cm height, 1 ml column and used to predict chromatograms for 20 cm height columns from 40 ml to 160 L volume. Simulations were found to be in good agreement with experimental results. The envisaged approach could potentially reduce the number of experiments, shorten development time and reduce costs.

    Over many millions of years of independent evolution, placental, marsupial and monotreme mammals have diverged conspicuously in physiology, life history and reproductive ecology. The differences in life histories are particularly striking. Compared with placentals, marsupials exhibit shorter pregnancy, smaller size of offspring at birth and longer period of lactation in the pouch. Monotremes also exhibit short pregnancy, but incubate embryos in eggs, followed by a long period of post-hatching lactation. Using a large sample of mammalian species, we show that, remarkably, despite their very different life histories, the scaling of production rates is statistically indistinguishable across mammalian lineages. Apparently all mammals are subject to the same fundamental metabolic constraints on productivity, because they share similar body designs, vascular systems and costs of producing new tissue.

    A globalizing world increases immigration between nations, raising the question of how acculturation (or its lack) of immigrants and their descendants to host societies affects risk perceptions. A survey of Paterson, New Jersey, residents tested acculturation's associations with attitudes to air pollution and its management, and knowledge of and self-reported behaviors concerning air pollution. Linguistic and temporal proxy measures for acculturation were independent variables along with ethnicity, plus controls for gender, age, education, and income in multivariate analyses. About one-fifth of contrasts between non-Hispanic whites, non-Hispanic blacks, English-interviewed Hispanics, and Spanish-interviewed Hispanics were statistically significant (Bonferroni-corrected) and of medium or higher affect size, with most featuring the Spanish-interviewed Hispanics. Knowledge variables featured the most significant differences. Specifically, Spanish-interviewed Hispanics reported less concern, familiarity with pollution, recognition of high pollution, and vigorous outdoor activity, and greater belief that government overregulates pollution than English-interviewed Hispanics (and than the other two groups on most of these variables too). English-interviewed Hispanics did not differ from non-Hispanic whites, but did on several variables from non-Hispanic blacks. Temporal proxies of acculturation among the foreign-born were far less significant, but concern and familiarity with air pollution increased with time spent in the United States, while belief in overregulation and a positive trend in New Jersey pollution increased with time in the nation of origin. Implications of these acculturation and ethnicity findings for risk perception/communication research and practice are discussed. PMID:21231941

    In clinical studies of antidepressants, the Hamilton Depression Rating Scale (HAMD) total score has been the gold standard instrument for establishing and comparing the efficacy of new treatments. However, the HAMD is a multidimensional measure, which may reduce its ability to detect differences between treatments, in particular, changes in core symptoms of depression. Two meta-analyses were conducted to compare the responsiveness of the HAMD total score with several published unidimensional subscale scores based upon core symptoms of depression. The first compared the above instrument's ability to detect differences between fluoxetine and placebo across eight studies involving over 1600 patients. The second analysis involved four studies and over 1200 patients randomized to tricyclic antidepressants and placebo. In both meta-analyses, the unidimensional core subscales outperformed the HAMD total score at detecting treatment differences. The implications of this on sample sizes and power for clinical studies will be discussed. In fact, studies based on the observed effect sizes from the core subscales would require approximately one-third less patients than studies based on the HAMD total score. Effect sizes from each individual HAMD item will also be presented to help explain the differences in responsiveness between the scales. PMID:10696827

    The stability of consumer-resource systems can depend on the form of feeding interactions (i.e. functional responses). Size-based models predict interactions - and thus stability - based on consumer-resource size ratios. However, little is known about how interaction contexts (e.g. simple or complex habitats) might alter scaling relationships. Addressing this, we experimentally measured interactions between a large size range of aquatic predators (4-6400 mg over 1347 feeding trials) and an invasive prey that transitions among habitats: from the water column (3D interactions) to simple and complex benthic substrates (2D interactions). Simple and complex substrates mediated successive reductions in capture rates - particularly around the unimodal optimum - and promoted prey population stability in model simulations. Many real consumer-resource systems transition between 2D and 3D interactions, and along complexity gradients. Thus, Context-Dependent Scaling (CDS) of feeding interactions could represent an unrecognised aspect of food webs, and quantifying the extent of CDS might enhance predictive ecology. PMID:27094829

    Standard metabolic rate (SMR, ml O2 min(-1)) of captive Crocodylus porosus at 30 °C scales with body mass (kg) according to the equation, SMR = 1.01 M(0.829), in animals ranging in body mass of 3.3 orders of magnitude (0.19-389 kg). The exponent is significantly higher than 0.75, so does not conform to quarter-power scaling theory, but rather is likely an emergent property with no single explanation. SMR at 1 kg body mass is similar to the literature for C. porosus and for alligators. The high exponent is not related to feeding, growth, or obesity of captive animals. The log-transformed data appear slightly curved, mainly because SMR is somewhat low in many of the largest animals (291-389 kg). A 3-parameter model is scarcely different from the linear one, but reveals a declining exponent between 0.862 and 0.798. A non-linear model on arithmetic axes overestimates SMR in 70% of the smallest animals and does not satisfactorily represent the data. PMID:23233168

    The present exploratory study examined the role of acculturation in the perception of the risks of smoking following a smoking cessation induction intervention among Latino caregivers of children with asthma. The sample consisted of 131 Latino smokers (72.9% female; 18.3% born in the U.S.) who were caregivers of a child with asthma. Caregivers were randomized to one of two smoking cessation interventions that were part of a home-based asthma program. Self-report measures of risk-perception were assessed at baseline, end of treatment (2 months after baseline), and 2- and 3-months post-treatment. At baseline, caregivers, regardless of level of acculturation, reported moderate to high levels of concern about the effects of secondhand smoke on their child's health as well as perceived risk regarding the effect of smoking on their own health. However, caregivers who were low in acculturation had a greater increase in concern about the effects of smoking on their child from pre-to post treatment compared to those who were high in acculturation (p = .001). Lastly, level of acculturation moderated the association between caregivers' concern about smoking on their child's health and their motivation to quit smoking (p < .05), but not cessation rates or reduced secondhand smoke exposure (p > .05). Specifically, motivation to quit at 3 months was greater for those with low acculturation. Though exploratory, these findings suggest that risk perception may be more easily influenced in low versus high acculturated populations and this should be considered in the design of clinical interventions and potentially mass media campaigns seeking to influence risk of caregiver behavior on child health with ethnic and racial minorities.

    The demographics of the United States are rapidly changing as a result of immigration from Latin America. Predictions indicate that by the year 2050, one of every four persons in the United States will be of Hispanic ethnicity. If health disparities relating to substance abuse and related mental health conditions among Hispanics are not fully understood and addressed, these will continue to grow along with this population. The purpose of this pilot study was to describe the relationships among acculturation, depression, self-esteem, and substance abuse among a community sample of Hispanic men in South Florida (N = 164, 82 heterosexual men and 82 men who have sex with men). Standardized instruments measuring acculturation, depression, self-esteem, and substance abuse were administered in English or Spanish in a face-to-face interview format. Descriptive statistics and multiple logistic regression were used to illustrate participant characteristics and test relationships among the variables. Despite the fact that the majority of participants were more acculturated to the Hispanic culture than US culture, reported low levels of education and income, were depressed, and used substances, this group of men reported high levels of self-esteem. However, age and depression were the only predictors of substance abuse. Acculturation and self-esteem were not predictors of substance abuse. Clinicians need to be aware of the high rates of depression and substance abuse in this population and screen frequently for signs and symptoms of depression and substance abuse during health care encounters.

  12. Freely expanding detonation products: Scaling of rate processes

    1988-03-01

    Using the Los Alamos reactive hydrodynamics code KIVA, calculations have been made to simulate the free expansion of cylinders of detonation products into a high vacuum. The emphasis of this paper is on the scaling of rate processes with cylinder size and initial conditions as a function of position in the expanding mass. The processes considered include diffusion, unimolecular decomposition, biomolecular radical reactions, and vibrational relaxation. The calculations also give time-dependent velocity fields; schlieren images; and profiles of density, pressure, and temperature. Many features of the calculations can be compared with experimental observations, including time-delayed schlieren and shadowgraph snapshots, time-dependent absorption spectra, and time-of-arrival profiles of molecular species. Some unexpected insights, such as the effect of the equation of state on the shape of the expanding plume and the effect of position on the rate of quenching, are discussed. These calculations are being used to interpret the available experimental data and to design future experiments.

    The Cooper-Harper (1969) scale has been extensively used for evaluation of aircraft handling qualities and associated mental workload. The scale is a 10-point scale with a decision tree. A modified version of the scale, called the MCH scale, has been devised for the purpose of assessing workload in systems other than those where the human operator performs motor tasks; namely, where perceptual, mediational, and communications activity is preent. The MCH scale has been validated in three different experiments. The scale is recommended for applications in which overall mental workload is to be assessed.

    Given the importance of a positive attitude towards one's own aging, we examined its predictors in a sample of 230 Korean American older adults (M (age) = 69.8 years, SD = 7.05). Personal views about aging, measured with a subscale of the Philadelphia Geriatric Center Morale Scale (PGCMS), were regressed on demographic variables, physical health-related factors, and psychosocial attributes (social network and acculturation). Results from the hierarchical regression analysis showed that better physical health conditions (fewer chronic conditions, less functional disability, and better vision) were associated with more positive personal views about aging. Other significant contributors included larger social networks and higher levels of acculturation. Findings suggest that personal views about aging among immigrant elderly populations can be enhanced by promoting physical health, social connectedness, and acculturation. Ways to maintain and improve positive attitudes about personal aging are discussed in a cultural context. PMID:22581472

    In this work, we reanalyze the heart rate variability (HRV) data from the 2002 Computers in Cardiology (CiC) Challenge using the concept of large-scale dimension densities and additionally apply this technique to data of healthy persons and of patients with cardiac diseases. The large-scale dimension density (LASDID) is estimated from the time series using a normalized Grassberger-Procaccia algorithm, which leads to a suitable correction of systematic errors produced by boundary effects in the rather large scales of a system. This way, it is possible to analyze rather short, nonstationary, and unfiltered data, such as HRV. Moreover, this method allows us to analyze short parts of the data and to look for differences between day and night. The circadian changes in the dimension density enable us to distinguish almost completely between real data and computer-generated data from the CiC 2002 challenge using only one parameter. In the second part we analyzed the data of 15 patients with atrial fibrillation (AF), 15 patients with congestive heart failure (CHF), 15 elderly healthy subjects (EH), as well as 18 young and healthy persons (YH). With our method we are able to separate completely the AF (ρlsμ=0.97±0.02) group from the others and, especially during daytime, the CHF patients show significant differences from the young and elderly healthy volunteers (CHF, 0.65±0.13 ; EH, 0.54±0.05 ; YH, 0.57±0.05 ; p<0.05 for both comparisons). Moreover, for the CHF patients we find no circadian changes in ρlsμ (day, 0.65±0.13 ; night, 0.66±0.12 ; n.s.) in contrast to healthy controls (day, 0.54±0.05 ; night, 0.61±0.05 ; p=0.002 ). Correlation analysis showed no statistical significant relation between standard HRV and circadian LASDID, demonstrating a possibly independent application of our method for clinical risk stratification.

    This study investigates bilingual performance on the English and Spanish Boston Naming Tests (BNTs) while controlling for object familiarity and U.S. acculturation. Previous studies suggest that bilingualism negatively affects naming skill; however, object familiarity, which may be culturally influenced, and U.S. acculturation level have not been formally investigated. The current sample comprised 74 well-acculturated bilinguals and 52 English monolinguals. Participants judged their familiarity with BNT objects and later named the objects in either English or Spanish. Both groups rated BNT objects to be comparably familiar. However, bilinguals underperformed relative to monolinguals. In fact, those bilinguals born and raised in the USA and educated solely under English instruction were unable to match monolinguals' superior naming performance. These results underscore a language disadvantage in naming even for native-born, highly acculturated, English proficient bilinguals and suggest that the BNT is language specific and perhaps unsuitable for testing bilingual populations.

    Cultural factors are often neglected in studies of suicidal behavior among emerging adults. The present study examined acculturative stress and perceived discrimination as statistical predictors of a suicide attempt history among an ethnically diverse sample of 969 emerging adults, ages 18-25 (M = 18.8). Females made up 68% of the sample, and the racial/ethnic composition included Asian, Latino, Black, and White (US-born and non-US-born) individuals. There were no statistically significant racial/ethnic differences in endorsement of a suicide attempt history, with an overall rate of 8% in the sample. Asian participants reported higher acculturative stress than all other racial/ethnic groups, while both Asian and Black participants reported having experienced more discrimination in the previous year, compared to other groups. Logistic regression analyses suggested that familial acculturative stress was associated with 2 times higher odds of endorsing a past suicide attempt, overall. More specifically, it was associated with over 2 times higher odds among Asian participants, over 4 times higher odds among Black participants, and over 3 times higher odds among non-US-born White participants, while social acculturative stress was associated with over 3 times higher odds of endorsing a past suicide attempt among Latino participants. Environmental acculturative stress was associated with decreased odds of endorsing a suicide attempt history, overall, but not when examined separately by racial/ethnic group. Perceived discrimination was associated with over 5 times higher odds of a suicide attempt, overall, and specifically was associated with over 3 times higher odds among Latino participants and over 10 times higher odds among White, US-born participants. These findings suggest the importance of addressing culturally-related variables in treatment with emerging adults of racially/ethnically diverse backgrounds to reduce risk for suicidal behavior.

  19. Uncinate Process Length in Birds Scales with Resting Metabolic Rate

    2009-01-01

    A fundamental function of the respiratory system is the supply of oxygen to meet metabolic demand. Morphological constraints on the supply of oxygen, such as the structure of the lung, have previously been studied in birds. Recent research has shown that uncinate processes (UP) are important respiratory structures in birds, facilitating inspiratory and expiratory movements of the ribs and sternum. Uncinate process length (UPL) is important for determining the mechanical advantage for these respiratory movements. Here we report on the relationship between UPL, body size, metabolic demand and locomotor specialisation in birds. UPL was found to scale isometrically with body mass. Process length is greatest in specialist diving birds, shortest in walking birds and intermediate length in all others relative to body size. Examination of the interaction between the length of the UP and metabolic demand indicated that, relative to body size, species with high metabolic rates have corresponding elongated UP. We propose that elongated UP confer an advantage on the supply of oxygen, perhaps by improving the mechanical advantage and reducing the energetic cost of movements of the ribs and sternum.

    Mathematics is an essential and fundamental tool used by engineers to analyse and solve problems in their field. Due to this, most engineering education programs involve a concentration of study in mathematics courses whereby engineering students have to take mathematics courses such as numerical methods, differential equations and calculus in the first two years and continue to do so until the completion of the sequence. However, the students struggled and had difficulties in learning courses that require mathematical abilities. Hence, this study presents the factors that caused mathematics anxiety among engineering students using Abbreviated Mathematics Anxiety Rating Scale (AMARS) through 95 students of Universiti Teknikal Malaysia Melaka (UTeM). From 25 items in AMARS, principal component analysis (PCA) suggested that there are four mathematics anxiety factors, namely experiences of learning mathematics, cognitive skills, mathematics evaluation anxiety and students' perception on mathematics. Minitab 16 software was used to analyse the nonparametric statistics. Kruskal-Wallis Test indicated that there is a significant difference in the experience of learning mathematics and mathematics evaluation anxiety among races. The Chi-Square Test of Independence revealed that the experience of learning mathematics, cognitive skills and mathematics evaluation anxiety depend on the results of their SPM additional mathematics. Based on this study, it is recommended to address the anxiety problems among engineering students at the early stage of studying in the university. Thus, lecturers should play their part by ensuring a positive classroom environment which encourages students to study mathematics without fear.

    The present study tests the hypothesis that involvement with a new culture instigates changes in personality of immigrants that result in (a) better fit with the norms of the culture of destination and (b) reduced fit with the norms of the culture of origin. Participants were 40 Japanese first-generation immigrants to the United States, 57 Japanese monoculturals, and 60 U.S. monoculturals. All participants completed the Jackson Personality Inventory (JPI) as a measure of the Big Five; immigrants completed the Japanese American Acculturation Scale. Immigrants’ fits with the cultures of destination and origin were calculated by correlating Japanese American mothers’ patterns of ratings on the Big Five with the average patterns of ratings of European Americans and Japanese on the same personality dimensions. Japanese Americans became more “American” and less “Japanese” in their personality as they reported higher participation in the U.S. culture. The results support the view that personality can be subject to cultural influence. PMID:23935211

    The Korean population in the US increased by a third between 2000 and 2010. Korean women in the US report low calcium intake and relatively high rate of fractures. However, little is known about the prevalence of osteoporosis among Korean American women. This paper examined the relationship between prevalence of osteoporosis and milk consumption, and their relationship with acculturation among a representative sample of immigrant California women of Korean descent. Bilingual telephone surveys were conducted from a probability sample (N = 590) in 2007. Lower acculturation significantly related to lower milk consumption for women during the age periods of 12-18 and 19-34 years. Acculturation was related to higher prevalence of osteoporosis among post-menopausal, but not pre-menopausal Korean women in California. Future research should include larger cohorts, objective measures of osteoporosis, other sources of calcium specific to Korean cuisine, and assessment of bone-loading physical activity.

    This study examined the relationship between indicators of acculturation and weight loss strategies among Latinas. Latinas residing in the United States longer had more experience with various weight loss strategies (r = 0.24, p = 0.05). Controlling for demographic factors and BMI, years of U.S. residence was related to whether increased physical activity (OR 1.18, 95% CI 1.01-1.39, p = 0.04) and reduced portion sizes (OR 1.39, 95% CI 1.02-1.91, p = 0.03) were used as strategies for weight loss. More English spoken at home was associated with use of reducing calories as a strategy for weight loss (OR 4.13, 95% CI 1.06-16.09, p = 0.04). Regardless of acculturation level, less empirically supported methods such as using herbal products and a girdle were more prevalent than commonly recommended methods such as using meal replacement products and commercial weight loss programs. Behavioral weight loss interventions for Latinas should consider acculturation to more effectively target subgroups, address cultural practices, and teach lifestyle-appropriate strategies.

    Background. The study examined the association of obesity with acculturation in a large and diverse sample of US Hispanic/Latino adults. Methods. The Hispanic Community Health Study (HCHS)/Study of Latinos (SOL) is a community-based cohort study of Hispanic/Latino adults aged 18–74 years (N = 16,415) from four urban areas. Height and weight were directly measured using a standardized protocol. Acculturation was assessed by the Short Acculturation Scale for Hispanics (SASH). Other immigration related variables included place of birth, length of residency in the US, and age at immigration. Odds ratios were calculated to assess the association of overweight, moderate obesity, and extreme obesity (≥40 kg/m2) with acculturation and sociodemographic variables. Results. The prevalence of obesity was 42.4% for women and 36.5% for men and varied by field center and Hispanic/Latino background. The strongest predictor of moderate and extreme obesity was length of residency in mainland US. This association was consistent across Hispanic/Latino backgrounds. Acculturation was not significantly associated with obesity. Discussion. The burden of obesity is high among Hispanic/Latino adults. The study findings suggest that prolonged exposure to the environments in these communities, rather than acculturation, is an important risk factor for obesity in this population. PMID:25893114

  8. [Diagnosis and symptom rating scale of restless legs syndrome].

    PubMed

    Inoue, Yuichi

    2009-05-01

    Restless legs syndrome (RLS) is a sensorimotor disorder, characterized by an irresistible urge to move the legs and usually accompanied or caused by uncomfortable and unpleasant sensations. It begins or worsens during periods of rest or inactivity, is partially or totally relieved by movement and is exacerbated or occurs mainly in the evening or night. People suffering from RLS are estimated to represent 2-3% of the general Japanese population, which is relatively lower than the estimated prevalence in western countries. Supportive diagnostic critevia include family history, the presence of periodic-leg movements (PLM) when awake or asleep, and a positive response to dopaminergic treatment. RLS phenotypes include an early onset form that is usually idiopathic with frequent familial history and a late onset form that is usually secondary to other somatic conditions that are causative factors in RLS occurrence. In all patients presenting with complaints of insomnia or discomfort in the lower limbs, diagnosis of RLS should be considered. RLS should be differentiated from akathisia, which is an urge to move the whole body in the absence of uncomfortable sensations. Polysomnographic studies and the suggested immobilization test (SIT) can detect PLM in patients that are asleep or awake. RLS may cause severe sleep disturbances, poor quality of life, depressive and anxious symptoms, and may be a risk factor for cardiovascular disease. Secondary RLS may occur due to iron deficiency, end-stage renal disease, pregnancy, peripheral neuropathy and drug use including antipsychotics and antidepressants. Small fiber neuropathy can trigger RLS or mimic its symptoms. RLS is associated with many neurological disorders, including Parkinson disease and multiple system atrophy; althoughit does not predispose to these diseases. A symptom rating scale for RLS authorized by the International RLS Study Group (IRLS) would facilitate accurate diagnosis of this condition. PMID:19514513

    We find that a universal homogeneous scaling form describes the distribution of cardiac variations for a group of healthy subjects, which is stable over a wide range of time scales. However, a similar scaling function does not exist for a group with a common cardiopulmonary instability associated with sleep apnea. Subtle differences in the distributions for the day- and night-phase dynamics for healthy subjects are detected.

    1982-01-01

    A new scale, comprising 100 criteria based on medical history, physical examination and routine laboratory data, independent of a drinking history, can help physicians in the detection, diagnosis and early treatment of alcoholism. The scale also permits objective classification of alcoholism into mild, moderate and severe categories and overcomes the patient's denial—a major obstacle to early diagnosis. Results suggest that the instrument is accurate: 94% of patients were classified correctly by the scale. Further validation studies in clinical practice are necessary. PMID:21286108

  16. Development of a scale to measure individuals’ ratings of peace

    PubMed Central

    2014-01-01

    Background The evolving concept of peace-building and the interplay between peace and health is examined in many venues, including at the World Health Assembly. However, without a metric to determine effectiveness of intervention programs all efforts are prone to subjective assessment. This paper develops a psychometric index that lays the foundation for measuring community peace stemming from intervention programs. Methods After developing a working definition of ‘peace’ and delineating a Peace Evaluation Across Cultures and Environments (PEACE) scale with seven constructs comprised of 71 items, a beta version of the index was pilot-tested. Two hundred and fifty subjects in three sites in the U.S. were studied using a five-point Likert scale to evaluate the psychometric functioning of the PEACE scale. Known groups validation was performed using the SOS-10. In addition, test-retest reliability was performed on 20 subjects. Results The preliminary data demonstrated that the scale has acceptable psychometric properties for measuring an individual’s level of peacefulness. The study also provides reliability and validity data for the scale. The data demonstrated internal consistency, correlation between data and psychological well-being, and test-retest reliability. Conclusions The PEACE scale may serve as a novel assessment tool in the health sector and be valuable in monitoring and evaluating the peace-building impact of health initiatives in conflict-affected regions.

    2014-01-01

    Introduction US Latinos are growing at the fastest rate of any racial/ethnic group in the United States and have the highest lifetime risk of diabetes. Acculturation may increase the risk of diabetes among all Latinos, but this hypothesis has not been studied in a nationally representative sample. The objective of this study was to test the hypothesis that acculturation was associated with an increased risk of diabetes in such a sample. Methods We conducted a cross-sectional analysis including 3,165 Latino participants in the 2007–2010 National Health and Nutrition Examination Survey. Participants with doctor-diagnosed diabetes and participants without diagnosed diabetes who had glycated hemoglobin (HbA1C) values of 6.5% or higher were classified as having diabetes. An acculturation score, ranging from 0 (lowest) to 3 (highest), was calculated by giving 1 point for each of 3 characteristics: being born in the United States, speaking predominantly English, and living in the United States for 20 years or more. Logistic regression was used to determine the association between acculturation and diabetes. Results The prevalence of diabetes among Latinos in our sample was 12.4%. After adjusting for sociodemographic factors, the likelihood of diabetes (95% confidence interval [CI]) increased with level of acculturation— 1.71 (95% CI, 1.31–2.23), 1.63 (95% CI, 1.11–2.39), and 2.05 (95% CI, 1.27–3.29) for scores of 1, 2, and 3, respectively. This association persisted after further adjustment for body mass index (BMI), total dietary calories, and physical inactivity. Conclusion Acculturation was associated with a higher risk of diabetes among US Latinos, and this risk was only partly explained by BMI and weight-related behaviors. Future research should examine the bio-behavioral mechanisms that underlie the relationship between acculturation and diabetes in Latinos. PMID:25299982

    Extant studies on the links between acculturation and mental and substance use disorders among Asian/Pacific Islanders have been based on the assumption that acculturation is a homogeneous construct. However, emerging evidence suggests that the various components of acculturation do not manifest independently, but rather cluster in ways that reflect distinct profiles. We employ data on Asian/Pacific Islanders from the National Epidemiologic Survey on Alcohol and Related Conditions (n = 968). Latent profile analysis is used to identify acculturation subgroups on the basis of indicator variables related to cultural identification, language ability and preference, and social engagement. Subsequently, the distribution of outcome variables in the domains of DSM disorders (lifetime history of clinical, personality, and substance use disorders) is examined across latent subgroups. We identified a 5-class solution: Class 1: Separated (12.91%), Class 2: Partial Bilingual/Bicultural (30.06%), Class 3: English Dominant/Asian Oriented (12.29%), Class 4: Full Bilingual/Bicultural (19.42%) and Class 5: Assimilated (25.31%). The highest rates of clinical disorders were observed among members of the 2 classes characterized by a strong preference for the use of the English language (Classes 3 and 5). The highest prevalence of nicotine (12%) and illicit drug use (15%) disorders was observed among members of the Assimilated class. Consistent with prior research, findings suggest that risk of morbidity is greater among more acculturated individuals; however, findings also suggest that an important level of nuance can be observed with respect to acculturative subtypes identified on the basis of cultural identification, language ability and preference, and social engagement.

    Immigrant adolescents have to navigate through a complex social environment consisting of, at least, both a native and a co-ethnic community. This study used a multi-level framework to consider two research questions involving this complexity. The individual-level associations of acculturation orientations and acculturative hassles (language and sociocultural adaptation) was assessed in immigrant youths, and whether this association differs depending on the school-level acculturation orientations held by co-ethnic peers, and the school-level orientations toward immigrants held by native German peers. We then investigated whether acculturative hassles are associated with the psychosocial functioning (self-efficacy, depressive symptoms) of immigrant adolescents. The sample comprised 650 ethnic German Diaspora migrant adolescents (mean age 15.6 years, 53.7 % female) and their 787 native German peers (mean age 15.05 years, 51 % female). The results showed that contextual factors (co-ethnic acculturation orientation, native friendship preferences) moderated the association between the acculturation orientations of adolescent immigrants and both types of acculturative hassles. Acculturative hassles, in turn, were associated with the psychosocial functioning of adolescents. This research demonstrates that a person-by-context perspective is needed to better understand the adaptation of adolescent immigrants. This perspective has to take into account both the native and the co-ethnic peer environment. PMID:26092230

    2013-03-15

    Scale-dependency of uranyl[U(VI)] surface complexation rates was investigated in stirred flow-cell and column systems using a U(VI)-contaminated sediment from the US Department of Energy, Hanford site, WA. The experimental results were used to estimate the apparent rate of U(VI) surface complexation at the grain-scale and in porous media. Numerical simulations using molecular, pore-scale, and continuum models were performed to provide insights into and to estimate the rate constants of U(VI) surface complexation at the different scales. The results showed that the grain-scale rate constant of U(VI) surface complexation was over 3 to 10 orders of magnitude smaller, dependent on the temporal scale, than the rate constant calculated using the molecular simulations. The grain-scale rate was faster initially and slower with time, showing the temporal scale-dependency. The largest rate constant at the grain-scale decreased additional 2 orders of magnitude when the rate was scaled to the porous media in the column. The scaling effect from the grain-scale to the porous media became less important for the slower sorption sites. Pore-scale simulations revealed the importance of coupled mass transport and reactions in both intragranular and inter-granular domains, which caused both spatial and temporal dependence of U(VI) surface complexation rates in the sediment. Pore-scale simulations also revealed a new rate-limiting mechanism in the intragranular porous domains that the rate of coupled diffusion and surface complexation reaction was slower than either process alone. The results provided important implications for developing models to scale geochemical/biogeochemical reactions.

    Our study investigated mental health and associated factors, especially acculturation stress and coping resources, among "marriage migrant" women. Cross-sectional data were collected for 501 marriage migrant women, about 10 % of those living in Busan, South Korea. Acculturation stress, coping resources, sociodemographic factors were examined using structured questionnaires, and the General Health Questionnaire-28 was administered as a measure of mental health. Many factors were related to mental health, especially marital satisfaction. Core cultural shock and self-rated economic status, interpersonal stress, and social support were also significantly related to mental health status. This study highlights the importance of marriage migrant women's mental health in South Korea. To improve their mental health, increased marital satisfaction, social support, resettlement funds, and/or educational programs that foster coping are needed. Additionally, we should encourage establishment of and participation in marriage migrant self-help groups, which can facilitate adaptation to marriage and to Korean culture. PMID:24292496

    The results of a study looking into the association between thyroid status and depression in the postpartum period were reanalysed to explore the psychometric properties of the rating scales employed. The performance of the Edinburgh Postnatal Depression Scale was found to be superior to that of the Hospital Anxiety and Depression Scale in identifying RDC-defined depression, and on a par with the observer-rated Hamilton Rating Scale for Depression, which it also matched for sensitivity to change in mood state over time. The anxiety subscale of the Hospital Anxiety and Depression Scale performed well, reflecting the fact that anxiety represents a prominent symptom in postnatal depression. PMID:9761410

  13. Examining rating scales using Rasch and Mokken models for rater-mediated assessments.

    Wind, Stephanie A

    2014-01-01

    A variety of methods for evaluating the psychometric quality of rater-mediated assessments have been proposed, including rater effects based on latent trait models (e.g., Engelhard, 2013; Wolfe, 2009). Although information about rater effects contributes to the interpretation and use of rater-assigned scores, it is also important to consider ratings in terms of the structure of the rating scale on which scores are assigned. Further, concern with the validity of rater-assigned scores necessitates investigation of these quality control indices within student subgroups, such as gender, language, and race/ethnicity groups. Using a set of guidelines for evaluating the interpretation and use of rating scales adapted from Linacre (1999, 2004), this study demonstrates methods that can be used to examine rating scale functioning within and across student subgroups with indicators from Rasch measurement theory (Rasch, 1960) and Mokken scale analysis (Mokken, 1971). Specifically, this study illustrates indices of rating scale effectiveness based on Rasch models and models adapted from Mokken scaling, and considers whether the two approaches to evaluating the interpretation and use of rating scales lead to comparable conclusions within the context of a large-scale rater-mediated writing assessment. Major findings suggest that indices of rating scale effectiveness based on a parametric and nonparametric approach provide related, but slightly different, information about the structure of rating scales. Implications for research, theory, and practice are discussed. PMID:24950531

    2015-06-01

    Cleveland and Laroche presented a scale to measure Acculturation to Global Consumer Culture. This measure was the first attempt to gauge consumer mindsets regarding their adaptation to global consumerism. Because this scale consisted of 57 scale items, applying such a lengthy scale can lead to response fatigue. Past research has also suggested that as more items are added to a scale, the informational value of each additional item is marginal. As an alternative, a shorter version of the Acculturation to Global Consumer Culture Scale is presented. The psychometric properties of this scale were verified via multiple group confirmatory factor analysis. A four-country investigation of young adults in China (n = 126; M age = 22.24 yr., SD = 3.63), New Zealand (n = 196; M age = 20.12 yr., SD = 4.12), Nigeria (n = 146; M age = 23.09 yr., SD = 3.80), and the United States (n = 120; M age = 21.67 yr., SD = 4.26) provides support for the cross-national applicability of the proposed parsimonious measure. Limitations and extensions are discussed. PMID:26030207

    Kim, Eunjung

    2011-01-01

    This study examined the links between intergenerational acculturation conflict and depression symptoms in 176 Korean American parents of children between the ages of 5 and 10. Approximately, 29% of fathers and 28% of mothers reported increased depression symptoms, which were related to parent-child acculturation conflict. Specific situations related to parental depression symptoms included conflicts over the child's social life, comparing the child with others, expressions of love, the importance of saving face, and proper Korean child's behavior. These findings can be used to develop a family intervention program to decrease parental depression symptoms by reducing parent-child acculturation conflict. PMID:21992260

    2014-10-01

    Grounded in a contextual approach to acculturation of minorities, this study examines changes in acculturation orientations among Palestinian Christian Arab adolescents in Israel following the "lost decade of Arab-Jewish coexistence." Multi-group acculturation orientations among 237 respondents were assessed vis-à-vis two majorities--Muslim Arabs and Israeli Jews--and compared to 1998 data. Separation was the strongest endorsed orientation towards both majority groups. Comparisons with the 1998 data also show a weakening of the Integration attitude towards Israeli Jews, and also distancing from Muslim Arabs. For the examination of the "Westernisation" hypothesis, multi-dimensional scaling (MDS) analyses of perceptions of Self and group values clearly showed that, after 10 years, Palestinian Christian Arabs perceive Israeli Jewish culture as less close to Western culture, and that Self and the Christian Arab group have become much closer, suggesting an increasing identification of Palestinian Christian Arab adolescents with their ethnoreligious culture. We discuss the value of a multi-group, multi-method, and multi-wave approach to the examination of the role of the political context in acculturation processes. PMID:25178958

    2010-01-01

    Objective A cross-sectional study was conducted to examine factors associated with health behaviors, including physical activity and dietary intake, of Chinese women who have immigrated to the United States and their children. Participants Using convenience sampling, a total of 65 Chinese-American children and their mothers in the San Francisco Bay Area participated in the study. Measures Information related to children’s weight, height, level of physical activity (Caltrac accelerometer), and dietary intake (Kids’ food frequency questionnaire) was collected using standardized instruments. Mothers completed questionnaires regarding household income, their levels of education and acculturation (Suinn-Lew Asian Self-Identity Acculturation Scale), dietary intake (SWAN Food Frequency Questionnaire), and level of physical activity (Seven-day physical activity recall). Results 36.9% (n = 24) of the children were overweight (body mass index higher than the 85th percentile). A high household income was related to low maternal body mass index (R2 = .08, P= .04), high maternal fat intake (R2 = .21, P = .0001), and high maternal intake of sweets (R2 = .08, P = .033), and a high level of maternal acculturation was related to low body mass index in children (R2 = .07, P = .034). Conclusions The results suggest that an intervention aimed at reducing obesity and promoting health behaviors must be appropriate for different ethnic groups with various incomes and levels of acculturation.

    2016-09-01

    The purpose of this research study was to examine whether level of acculturation is a predictor of body mass index, waist circumference, and waist-hip ratio in Filipino Americans with hypertension in the United States. The Filipino Americans (N = 108) were recruited from a primary care clinic in the United States. Two instruments were used to collect and operationalize the variables, specifically: (1) Socioeconomic/Demographic Questionnaire and (2) A Short Acculturation Scale for Filipino Americans. Descriptive statistics and partial least squares were used to calculate the results. The partial least square path model identified acculturation as a predictor of body mass index, wait circumference, and waist-hip ratio among Filipino Americans. The positive path coefficient (β = 0.384) was statistically significant (t = 5.92, P < .001). Health care providers need to stress the importance of the degree of acculturation when developing culturally appropriate lifestyle and health promotion interventions among immigrant patients with hypertension.

    2008-01-01

    This paper revisits a half-century long theoretical controversy associated with the use of magnitude estimation scaling (MES) and category rating scaling (CRS) procedures in measurement. The MES procedure in this study involved instructing participants to write a number that matched their impression of difficulty of a test item. Participants were not restricted in the range of numbers they could choose for their scale. They also had the choice of disclosing their individual scale. After the MES task was completed, participants were given a blank copy of the test to rate the perceived difficulty of each item using a researcher-imposed categorical rating scale from 1 (very easy) to 6 (very difficult). The MES and CRS data were both analyzed using Rasch Rating scale model. Additionally, the MES data were examined with Rasch Partial Credit model. Results indicate that knowing each person's scale is associated with smaller errors of measurement. PMID:18480511

    1994-01-01

    The purpose of the study was to investigate the use of teacher assessments in screening for learning disabilities. In a longitudinal study, 603 children were rated by their teachers in the second grade (age 8 to 9 years), and the ratings were correlated with examinations of reading, spelling, and intelligence in the third grade. The third-grade tests for reading, spelling, and intelligence classified children into groups with low achievement and dyslexia, and these two groups were compared with normally achieving children. The accuracy of teacher assessments, measured with correlation analysis, ROC curves, and kappa indices, showed that teachers were quite accurate in their judgment of low achievement, but somewhat less efficient in their judgment of specific reading difficulties.

    This study aimed to determine whether definable profiles existed in a cohort of nursing staff with regard to demographic characteristics, job satisfaction, acculturation, work environment, stress, cultural values and coping abilities. A survey was conducted in one hospital in Singapore from June to July 2012, and 814 full-time staff nurses completed a self-report questionnaire (89% response rate). Demographic characteristics, job satisfaction, acculturation, work environment, perceived stress, cultural values, ways of coping and intention to leave current workplace were assessed as outcomes. The two-step cluster analysis revealed three clusters. Nurses in cluster 1 (n = 222) had lower acculturation scores than nurses in cluster 3. Cluster 2 (n = 362) was a group of younger nurses who reported higher intention to leave (22.4%), stress level and job dissatisfaction than the other two clusters. Nurses in cluster 3 (n = 230) were mostly Singaporean and reported the lowest intention to leave (13.0%). Resources should be allocated to specifically address the needs of younger nurses and hopefully retain them in the profession. Management should focus their retention strategies on junior nurses and provide a work environment that helps to strengthen their intention to remain in nursing by increasing their job satisfaction.

    Most rating scales for affective disorders measure either depressive or hypomanic/manic symptoms and there are few scales for hypomania/mania in a self-rating format. We wanted to develop and validate a self-rating scale for comprehensive assessment of depressive, manic/hypomanic and mixed affective states. We developed an 18-item self-rating scale starting with the DSM-IV criteria for depression and mania, with subscales for depression and mania. The scale was evaluated on 61 patients with a diagnosis of affective disorder, predominantly bipolar disorder type I, using Montgomery-Asberg Depression Rating Scale (MADRS), Hypomania Interview Guide-Clinical version (HIGH-C) and Clinical Global Impression scale, modified for bipolar patients (CGI-BP) as reference scales. Internal consistency of the scale measured by Cronbach's alpha was 0.89 for the depression subscale and 0.91 for the mania subscale. Spearman's correlation coefficients (two-tailed) between the depression subscale and MADRS was 0.74 (P<0.01) and between mania subscale and HIGH-C 0.80 (P<0.01). A rotated factor analysis of the scale supported the separation of symptoms in the mania and depression subscale. We established that the self-rating scales sensitivity to identify mixed states, with combined cut-offs on the MADRS and HIGH-C as reference, was 0.90 with a specificity of 0.71. The study shows that the Affective Self Rating Scale is highly correlated with ratings of established interview scales for depression and mania and that it may aid the detection of mixed affective states.

    2011-11-01

    This study used data from 845 foreign-born (n = 328) and native-U.S. born (n = 517) Hispanic mothers who participated in the Fragile Families and Child Wellbeing Study (FFCWS) to examine four indicators of acculturation--nativity, years lived in the United States, religious attendance, and endorsement of traditional gender norms--as predictors of maternal physical aggression directed toward young children. The authors also examined whether psychosocial risk factors associated with child maltreatment and acculturation--maternal alcohol use, depression, parenting stress, and intimate partner aggression and violence--mediate relationships between acculturation and maternal aggression. Foreign-born Hispanic mothers had significantly lower rates of physical aggression than native-born Hispanic mothers. In path modeling results, U.S. nativity, along with maternal alcohol use, parenting stress, and child aggressive behavior, emerged as the strongest risk factors for maternal physical aggression. Among the four acculturation indicators, only foreign birth was directly associated with lower maternal aggression. Study findings suggest immigrant status is a unique protective factor that contributes to lower levels of physical aggression among Hispanic mothers. PMID:21926114

    1987-01-01

    The fuzzy Golay transformation is a novel approach for gray-level image processing. Fuzzy-set theory is used to modify the binary image processing techniques developed by M. J. Golay to permit direct gray-level image processing without thresholding. The comparison between gray-level pixels is accomplished with the Pixel Closeness Value (PCV) while comparison between gray-level neighborhoods uses the Neighborhood Closeness Value (NCV). Feature extraction is done by comparing the gray-level image neighborhood to a subset of the fourteen Golay neighborhoods using the NCV function. The Fuzzy Golay Processor (FGP) is an architecture designed to implement the fuzzy Golay transformation. The design of the FGP has been optimized to permit a successful implementation in Wafer Scale Integration (WSI). A system containing four FGPs is capable of performing thirty fuzzy Golay transformations per second on a 256 by 256 eight-bit pixel image. Such a system could fit on a four-inch wafer with enough redundant dies to allow a 30% die yield. The required dies are four Input-Output Modules (IOM) and 56 Neighborhood Evaluation Modules (NEM).

    2015-12-01

    Two studies addressed the role of Black meta-perception of acculturation attitudes on the relation between minority acculturation attitudes and their social adjustment (school achievement and perceived quality of intergroup relations). Participants in both studies were Black Lusophone adolescents living in Portugal. Study 1 (N = 140) indicated that participants' attitude regarding the host culture was positively correlated with their school achievement and to their evaluation of intergroup relations. It also indicated that participants' meta-perception of majority attitude add to the explained variance of participants' social adjustment. Study 2 (N = 62) manipulated the perceived majority high/low support of immigrants' learning the host culture. The dependent variable (DV) was perceived quality of intergroup relations. Only in the low support condition were participants' attitudes towards the host culture positively related to perceived quality of Black-White relationships. These results suggest that perceived social context is central to understand the relationship between minority adolescents' acculturation attitudes and key dimensions of their adjustment to host societies.

    2016-05-01

    Quantum quenches display universal scaling in several regimes. For quenches which start from a gapped phase and cross a critical point, with a rate slow compared to the initial gap, many systems obey Kibble-Zurek scaling. More recently, a different scaling behaviour has been shown to occur when the quench rate is fast compared to all other physical scales, but still slow compared to the UV cutoff. We investigate the passage from fast to slow quenches in scalar and fermionic free field theories with time dependent masses for which the dynamics can be solved exactly for all quench rates. We find that renormalized one point functions smoothly cross over between the regimes.

    2006-01-01

    Allometric scaling is one of the most pervasive laws in biology. Its origin, however, is still a matter of dispute. Recent studies have established that maximum metabolic rate scales with an exponent larger than that found for basal metabolism. This unpredicted result sets a challenge that can decide which of the concurrent hypotheses is the correct theory. Here, we show that both scaling laws can be deduced from a single network model. Besides the 3/4-law for basal metabolism, the model predicts that maximum metabolic rate scales as M, maximum heart rate as M, and muscular capillary density as M, in agreement with data.

    NASA Technical Reports Server (NTRS)

    Rubinstein, Robert; Ye, Zhou

    1997-01-01

    The dissipation rate transport equation remains the most uncertain part of turbulence modeling. The difficulties arc increased when external agencies like rotation prevent straightforward dimensional analysis from determining the correct form of the modelled equation. In this work, the dissipation rate transport equation and subgrid scale models for rotating turbulence are derived from an analytical statistical theory of rotating turbulence. In the strong rotation limit, the theory predicts a turbulent steady state in which the inertial range energy spectrum scales as k(sup -2) and the turbulent time scale is the inverse rotation rate. This scaling has been derived previously by heuristic arguments.

    2016-02-01

    Although migration itself may not compromise the mental health of immigrants, the acculturative process can involve highly stressful factors that are specific to immigrant and minority status. Using structural equation modeling, this study examined the relations between acculturation orientations, perceived discrimination, acculturative stress, and psychological distress among 229 Pakistani and 218 Nepalese migrants living in Hong Kong. Although the initial hypothesized model was not confirmed, a modified model with good fit indices showed that acculturation orientation mediated the relationships of perceived discrimination and acculturative stress with psychological distress. Of all the factors in the model, acculturative stress had the strongest association with psychological distress. PMID:26608650

    2015-09-01

    This manuscript provides a review of pore-scale researches in literature including experimental and numerical approaches, and scale-dependent behavior of geochemical and biogeochemical reaction rates in heterogeneous porous media. A mathematical equation that can be used to predict the scale-dependent behavior of geochemical reaction rates in heterogeneous porous media has been derived. The derived effective rate expression explicitly links the effective reaction rate constant to the intrinsic rate constant, and to the pore-scale variations in reactant concentrations in porous media. Molecular simulations to calculate the intrinsic rate constants were provided. A few examples of pore-scale simulations were used to demonstrate the application of the equation to calculate effective rate constants in heterogeneous materials. The results indicate that the deviation of effective rate constant from the intrinsic rate in heterogeneous porous media is caused by the pore-scale distributions of reactants and their correlation, which are affected by the pore-scale coupling of reactions and transport.

    The Modified Norris Scale is a rating scale for amyotrophic lateral sclerosis (ALS), which consists of two parts, the Limb Norris Scale and the Norris Bulbar Scale. The Limb Scale has 21 items to evaluate extremity function and the Bulbar Scale has 13 items to evaluate bulbar function. Each item is rated in 4 ordinal categories. Considering the habitual difference, we translated the English scale into Japanese one with minor modification, and added more detailed explanations for all categories of each item. Then we examined reliability and factorial structure of the translated scale. The subjects were 23 patients with motor disturbance and each subject was rated twice by 2-4 neurologists. As a measure of reliability, the Kappa coefficient proposed by Cohen (1960) and Kraemer (1980) was calculated for each item and the intraclass correlation coefficient (ICC) was evaluated for total scores of each of two scales. To analyze the factorial structure, the factor analysis was carried out. The minimum and the maximum Kappa values were .70 and .97 for intra-rater reliability of the Limb Scale's items, .60 and .83 for inter-rater reliability of the Limb Scale's items, .41 and 1.00 for intra-rater reliability of the Bulbar Scale's items and .26 and .81 for inter-rater reliability of the Bulbar Scale's items, respectively. Concerning the factorial structure, the contribution of the first factor was 83.6% for the Limb Scale and that for the Bulbar Scale was 66.7%. This indicates unidimensionality of both Scales. The ICCs for the total scores were .97 (95%C.I. .95-.99) for the Limb Scale and .86 (.73-.93) for the Bulbar Scale, respectively. On the basis of these results, the Scale has unidimensionality and high reliability enough for practical use. PMID:8951891

    Intimate partner violence has negative effects on women's safety and wellbeing. When immigrant women are victimized the danger and poor health may intensify. The purpose was to determine the impact of acculturation on severity of violence, danger for murder, mental health functioning, and safety behaviors of abused immigrant women. Entry data of a 7-year prospective study of 106 abused immigrant women who were first time users of safe shelter or justice services is presented. The interview included the Severity of Violence Against Women Scale, Danger Assessment, Brief Symptom Inventory (BSI), Safety Behavior Checklist, and Acculturation for Hispanics instruments. A significant (p < 0.05) positive correlation between acculturation and safety behaviors and BSI scores was established. Higher acculturation scores were associated with significantly more practiced safety behaviors and higher levels of depression. Understanding the specific needs of abuse immigrant women associated with acculturation is imperative to develop interventions to interrupt abuse and promote safety and mental well-being.

  12. Two-parameter characterization of chromosome-scale recombination rate.

    PubMed

    Li, Wentian; Freudenberg, Jan

    2009-12-01

    The genome-wide recombination rate (RR) of a species is often described by one parameter, the ratio between total genetic map length (G) and physical map length (P), measured in centimorgans per megabase (cM/Mb). The value of this parameter varies greatly between species, but the cause for these differences is not entirely clear. A constraining factor of overall RR in a species, which may cause increased RR for smaller chromosomes, is the requirement of at least one chiasma per chromosome (or chromosome arm) per meiosis. In the present study, we quantify the relative excess of recombination events on smaller chromosomes by a linear regression model, which relates the genetic length of chromosomes to their physical length. We find for several species that the two-parameter regression, G = G(0) + k x P , provides a better characterization of the relationship between genetic and physical map length than the one-parameter regression that runs through the origin. A nonzero intercept (G(0)) indicates a relative excess of recombination on smaller chromosomes in a genome. Given G(0), the parameter k predicts the increase of genetic map length over the increase of physical map length. The observed values of G(0) have a similar magnitude for diverse species, whereas k varies by two orders of magnitude. The implications of this strategy for the genetic maps of human, mouse, rat, chicken, honeybee, worm, and yeast are discussed. PMID:19752285

    Acculturation has been shown to positively and negatively affect Latino health. Little research investigates the overlap between acculturation and the different types of relationship violence among Latino youth and most research in this area predominantly involves Mexican-American samples. The current study examined associations between indices of acculturation (language use at home, chosen survey language, and nativity) and relationship physical violence and sexual coercion, both received and delivered, among predominantly Dominican and Puerto Rican adolescents from New York City. From 2006 to 2007, 1,454 adolescents aged 13-21 years in New York City completed an anonymous survey that included the Conflict in Adolescent Relationships Inventory which estimates experiences of physical violence and sexual coercion, both received and delivered, in the previous year. This analysis includes bivariate and multivariate methods to test the associations between language use at home, chosen survey language, and nativity with the different types of relationship violence. Among females, there is a significant association between language use at home and overall level of acculturation with delivering and receiving relationship physical violence; however, we did not find this association in delivering and receiving relationship sexual coercion. We found no association between acculturation and any type of relationship violence among males. Among Latina females, language spoken at home is an indicator of other protective factors of physical relationship violence. Future research in this area should explore the potential protective factors surrounding relationship violence among Latina females of various subgroups using comprehensive measures of acculturation, household composition and family engagement.

    Recent studies revealed a negative association between acculturation and sun-safe behaviors, possibly mediated by education level, health status, and social networks. We sought to elucidate this relationship by exploring the moderating effects of gender and health insurance on each mediated path. We used data from 496 Latino respondents to the 2005 Health Information National Trends Survey. Acculturation, assessed by a four-item index, was the primary predictor; use of sunscreen and protective clothing were the primary outcomes, assessed by frequency scales. Moderated mediation was tested with an established causal moderation method. The mediated association between acculturation, education level and sunscreen use might be stronger among women than men (P < 0.08). We found no evidence of moderated mediation for use of protective clothing. The findings suggest ways of refining the theoretical and empirical rationale for sun safety research and interventions with Latinos. Studies should replicate these models with longitudinal data.

    The goal of this review was to examine the state of Level 2, caregiver-completed rating scales for the screening of Autism Spectrum Disorders (ASDs) in individuals above the age of three years. We focused on screening accuracy and paid particular attention to comparison groups. Inclusion criteria required that scales be developed post ICD-10, be ASD-specific, and have published evidence of diagnostic validity in peer-reviewed journals. The five scales reviewed were: the Social Communication Questionnaire (SCQ), Gilliam Autism Rating Scale/Gilliam Autism Rating Scale-Second Edition (GARS/GARS-2), Social Responsiveness Scale (SRS), Autism Spectrum Screening Questionnaire (ASSQ), and Asperger Syndrome Diagnostic Scale (ASDS). Twenty total studies were located, most examining the SCQ. Research on the other scales was limited. Comparisons between scales were few and available evidence of diagnostic validity is scarce for certain subpopulations (e.g., lower functioning individuals, PDDNOS). Overall, the SCQ performed well, the SRS and ASSQ showed promise, and the GARS/GARS-2 and ASDS demonstrated poor sensitivity. This review indicates that Level 2 ASD caregiver-completed rating scales are in need of much more scientific scrutiny. PMID:20591956

    Depression is a common comorbid condition in Parkinson’s disease (PD) and a major contributor to poor quality of life and disability. However, depression can be difficult to assess in patients with PD due to overlapping symptoms and difficulties in the assessment of depression in cognitively impaired patients. As several rating scales have been used to assess depression in PD (dPD), the Movement Disorder Society commissioned a task force to assess their clinimetric properties and make clinical recommendations regarding their use. A systematic literature review was conducted to explore the use of depression scales in PD and determine which scales should be selected for this review. The scales reviewed were the Beck Depression Inventory (BDI), Hamilton Depression Scale (Ham-D), Hospital Anxiety and Depression Scale (HADS), Zung Self-Rating Depression Scale (SDS), Geriatric Depression Scale (GDS), Montgomery-As-berg Depression Rating Scale (MADRS), Unified Parkinson’s Disease Rating Scale (UPDRS) Part I, Cornell Scale for the Assessment of Depression in Dementia (CSDD), and the Center for Epidemiologic Studies Depression Scale (CES-D). Seven clinical researchers with clinical and research experience in the assessment of dPD were assigned to review the scales using a structured format. The most appropriate scale is dependent on the clinical or research goal. However, observer-rated scales are preferred if the study or clinical situation permits. For screening purposes, the HAM-D, BDI, HADS, MADRS, and GDS are valid in dPD. The CES-D and CSDD are alternative instruments that need validation in dPD. For measurement of severity of depressive symptoms, the Ham-D, MADRS, BDI, and SDS scales are recommended. Further studies are needed to validate the CSDD, which could be particularly useful for the assessment of severity of dPD in patients with comorbid dementia. To account for overlapping motor and nonmotor symptoms of depression, adjusted instrument cutoff scores may

    Just as big bang nucleosynthesis allows us to probe the expansion rate when the temperature of the Universe was around 1 MeV, the measurement of gravity waves from electroweak scale first order phase transitions may allow us to probe the expansion rate when the temperature of the Universe was at the electroweak scale. We compute the simple transformation rule for the gravity wave spectrum under the scaling transformation of the Hubble expansion rate. We then apply this directly to the scenario of quintessence kination domination and show how gravity wave spectra would shift relative to Laser Interferometer Space Antenna and Big Bang Observer projected sensitivities.

    Existing scales for rating the severity of blepharospasm (BSP) are limited by a number of potential drawbacks. We therefore developed and validated a novel scale for rating the severity of BSP. The development of the scale started with careful examination of the clinical spectrum of the condition by a panel of experts who selected phenomenological aspects thought to be relevant to disease severity. Thereafter, selected items were first checked for reliability, then reliable items were combined to generate the scale, and clinimetric properties of the scale were evaluated. Finally, the confidence with which the scale could be used by people without high levels of movement disorders skill was assessed. The new scale, based on objective criteria, yielded moderate to almost perfect reliability, acceptable internal consistency, satisfactory scaling assumptions, lack of floor and ceiling effects, partial correlations with a prior severity scale and with a quality of life scale, and good sensitivity to change. Despite a few limitations, the foregoing features make the novel scale more suitable than existing scales to assess the severity of BSP in natural history and pathophysiologic studies as well as in clinical trials.

    The present study explores the impact of acculturation on depressive symptoms among Turkish immigrants in Germany, taking into account different dimensions of cultural orientation. A total of 471 patients from two selected samples (254 primary care patients and 217 outpatients of a psychosomatic department) participated. Levels of acculturation were measured as orientation towards culture of origin (CO), and orientation towards the host culture (HC). Acculturation strategies (integration, assimilation, separation, and marginalization) were also assessed as well as their association with depressive symptoms (BDI). Furthermore, gender- and migration-related differences in terms of acculturation and levels of depressive symptomatology were analyzed. Integration was the acculturation strategy associated with the lowest level of depressive symptoms (M = 14.6, SD = 11.9), while marginalization was associated with the highest (M = 23.5, SD = 14.7). Gender was not found to have a significant impact on acculturation but influenced depressive symptoms, with women (M = 21.8, SD = 13.3) reporting higher levels of depressive symptomatology than men (M = 15.1, SD = 14.0; p < 0.001). In first generation immigrants, significantly higher CO (M = 46.6, SD = 8.3; p < 0.001), lower HC (M = 31.0, SD = 9.6; p < 0.001), and higher levels of depressive symptoms (M = 20.2, SD = 14.1; p < 0.001) were found in comparison to second generation immigrants (CO: M = 41.3, SD = 7.4; HC: M = 36.2, SD = 8.8; depressive symptoms: M = 14.0, SD = 12.9). Our results suggest that orientation towards both the heritage and the host culture has a positive effect on the mental health status of immigrants. Future research needs to include representative samples of migrants from different cultures to further explore the association between acculturation and mental health. PMID:25222474

    Behavior rating scales are commonly used in the assessment of attention deficit-hyperactivity disorder (ADHD). However, there is little information available concerning the extent to which scales are valid with culturally different students. This study explored the use of the ADHD-IV Rating Scale School Version with male Caucasian (CA) and African American (AA) students from ages 5 to 18 years. Teachers rated AA students higher on all symptoms across all age groups. LISREL analysis indicated that scale does not perform identically across groups. This was supported by the results of multidimensional scaling with suggested that there is a different relation between items across groups. Implications for research and practice are discussed.

  6. Assessing pain intensity following spinal cord injury: should rating scales measure 'overall' or 'maximal' values?

    PubMed

    2015-03-01

    Rating scales (RSs) are important for the assessment of pain intensity (PI) following a spinal cord injury (SCI). Using a Graphic Rating Scale, this pilot study measured an 'overall' level of PI repeated about every 2 h over 1 day and compared it with maximal PI scores reported previously. Patients were categorized into severity groups according to the overall Graphic Rating Scale score at initial assessment (T0). Eight men and six women (mean age 53.1; range 28-75) participated. Comparison of the overall PI scores and their changes over time with the maximal PI scores reported previously showed loss of patients in the severe group and less pronounced PI changes over time. Rating scales used in spinal cord injury services should measure maximal pain experienced 'right now' to eliminate potential averaging out of pain over time, which might allow physicians to assist patients in understanding their pain and begin their adjustment.

    Whilst neuropsychological research has enhanced our understanding of inattentive and hyperactive behaviours among children with intellectual disability (ID), the absence of rating scales developed for this group continues to be a gap in knowledge. This study examined these behaviours in 176 children with autism spectrum disorder (ASD), Down Syndrome (DS), or idiopathic ID using a newly developed teacher rating scale, the Scale of Attention in Intellectual Disability. Findings suggested that children with ASD had a significantly greater breadth of hyperactive/impulsive behaviours than those with DS or idiopathic ID. These findings support existing research suggesting differing profiles of attention and activity across groups. Understanding disorder-specific profiles has implications for developing strategies to support students with ID in the classroom. PMID:27348856

    Background: Pittsburgh insomnia rating scale is a 65 item self administered open source questionnaire. The scale is widely used in clinical practice but its psychometric properties are not well established. Therefore keeping in mind this lacuna the current study was designed for university population of poor sleepers in India. Aims: The purpose of this study was to establish the Pittsburgh sleep Quality Index test- retest reliability, validity and internal consistency of Pittsburgh insomnia rating scale. Materials and Methods: Twenty five subjects were randomly chosen from the screened population of poor sleepers. Pittsburgh insomnia rating scale, Pittsburgh sleep quality index and Insomnia severity index were administered on test day. Retest was administered after one week. Results: Eight males and seventeen females with mean age 24 + 7.04 were recruited. The test retest reliability for Pittsburgh insomnia rating scale total score showed excellent reliability (ICC2,1-0.93). The results also show that the total score is moderately correlated with Pittsburgh sleep Quality Index (r-0.31) and moderately correlated with Insomnia severity index (r-0.49). Internal consistency for the test was excellent (Cronbach's alpha- 0.930) Conclusion: The study findings suggest that Pittsburgh insomnia rating scale has excellent internal consistency, test-retest reliability and good validity for university population of poor sleepers in India.

    Delirium's characteristic fluctuation in symptom severity complicates the assessment of test-retest reliability of scales using classical analyses, but application of modelling to longitudinal data offers a new approach. We evaluated test-retest reliability of the delirium rating scale (DRS) and delirium rating scale-revised-98 (DRS-R98), two widely used instruments with high validity and inter-rater reliability. Two existing longitudinal datasets for each scale included DSM-IV criteria for delirium diagnosis and repeated measurements using the DRS or DRS-R98. To estimate the reliability coefficients RT and RΛ for each scale we used a macros provided by Dr. Laenen at http://www.ibiostat.be/software/measurement.asp. For each dataset a linear mixed-effects model was fitted to estimate the variance-covariance parameters. A total of 531 cases with between 4 and 9 measurement points across studies including both delirious and non-delirious patients. Comorbid dementia in the datasets varied from 27% to 55%. Overall RT for the DRS were 0.71 and 0.50 and for DRS-R98 0.75 and 0.84. RΛ values for DRS were 0.99 and 0.98 and for DRS-R98 were 0.92 and 0.96. Individual RT measures for DRS-R98 and DRS across visits within studies showed more range than overall values. Our models found high overall reliability for both scales. Multiple factors impact a scale's reliability values including sample size, repeated measurements, patient population, etc in addition to rater variability. PMID:23522935

    Identification of pharyngeal residue severity located in the valleculae and pyriform sinuses has always been a primary goal during fiberoptic endoscopic evaluation of swallowing (FEES). Pharyngeal residue is a clinical sign of potential prandial aspiration making an accurate description of its severity an important but difficult challenge. A reliable, validated, and generalizable pharyngeal residue severity rating scale for FEES would be beneficial. A systematic review of the published English language literature since 1995 was conducted to determine the quality of existing pharyngeal residue severity rating scales based on FEES. Databases were searched using controlled vocabulary words and synonymous free text words for topics of interest (deglutition disorders, pharyngeal residue, endoscopy, videofluoroscopy, fiberoptic technology, aspiration, etc.) and outcomes of interest (scores, scales, grades, tests, FEES, etc.). Search strategies were adjusted for syntax appropriate for each database/platform. Data sources included MEDLINE (OvidSP 1946-April Week 3 2015), Embase (OvidSP 1974-2015 April 20), Scopus (Elsevier), and the unindexed material in PubMed (NLM/NIH) were searched for relevant articles. Supplementary efforts to identify studies included checking reference lists of articles retrieved. Scales were compared using qualitative properties (sample size, severity definitions, number of raters, and raters' experience and training) and psychometric analyses (randomization, intra- and inter-rater reliability, and construct validity). Seven articles describing pharyngeal residue severity rating scales met inclusion criteria. Six of seven scales had insufficient data to support their use as evidenced by methodological weaknesses with both qualitative properties and psychometric analyses. There is a need for qualitative and psychometrically reliable, validated, and generalizable pharyngeal residue severity rating scales that are anatomically specific, image

    Objective Our knowledge of acculturative processes and their impact on immigrant families remains quite limited. Acculturative Family Distancing (AFD) is the distancing that occurs between immigrant parents and their children, and is caused by breakdowns in communication and cultural value differences. It is a more proximal and problem-focused formulation of the acculturation gap and is hypothesized to increase depression via family conflict. Method Data were collected from 105 Chinese American high school students and their mothers. Rasch modeling was used to refine the AFD measure and structural equation modeling was used to determine the effects of AFD on youth and maternal depression. Results Findings indicate that greater AFD was associated with higher depressive symptoms and risk for clinical depression. Family conflict partially mediated this relation for youth, whereas for mothers, AFD directly increased risk for depression. Greater mother-child heritage enculturation discrepancies were associated with greater mother and child AFD. Mainstream acculturation discrepancies and language gaps between mothers and youth were not significantly associated with any of the primary outcome variables. Conclusions Results highlight the need to better understand how AFD and other acculturation-gap phenomena affect immigrant mental health. They also underscore the need to develop prevention and intervention programs that target communication difficulties and intergenerational cultural value differences. PMID:20873901

    The bedload transport rate is of large fluctuation across several time scales. Understanding bedload transport fluctuation would be helpful for modeling the transport process. In this talk, we first report a multi-scale phenomenon of fluctuation of bedload transport rate by an experimental study. Analysis of the experimental results shows that the fluctuations of bedload transport rates decay with the sampling time scales. A clear three-stage scale-dependent decaying process can be found. Then, an expression for the dependence of the fluctuation of bedload transport rates on the sampling time scales is derived from a stochastic theory (Ancey et al., 2008). The expression is consistent with experimental observations demonstrating that the bedload transport rates behave as a homogeneous Piosson process at the small time scales, which is consistent with Einstein's theory. However, at the media and large time scales, the internal memory of the stochastic sediment dynamics would induce more fluctuations. It is closely related to the collective entrainment mechanism of bedload transport which was newly introduced by Ancey's theory. Together with the very recent finding by Heyman et al. (2012), our theoretical expressions can calibrate all the necessary parameters in Ancey's theory by the experimental observation of bedload transport rates.; The fluctuation of bedload transport rates at different sampling time scales.

  20. Assessment and treatment of dysthymia. The development of the Cornell dysthymia rating scale.

    Cohen, J

    1997-01-01

    The understanding and classification of persistently depressed mood has undergone many changes since the term 'dysthymia' was first used nearly 150 years ago. Originally it was applied to both melancholia and mania; later it was applied to depressive personality. The Diagnostic and Statistical Manual (DSM)-III in 1980 and in subsequent updates classified dysthymia as a mood disorder, characterized by a frequently insidious onset and a course that is chronic and unremitting. The assessment of clinical response in the pharmacologic treatment of dysthymia has been more difficult than that for major depression. The Hamilton Rating Scale for Depression, among others, is oriented towards episodic rather than chronic states of depression. A new rating scale, the Cornell Dysthymia Rating Scale, has been developed to better assess milder symptomatology in chronically depressed patients. Early studies suggest its utility, but further validation of the scale is needed in patients with dysthymia and without major depression. PMID:19698530

    2013-01-01

    Combining the Capacitively Coupled Contactless Conductivity Detection (C4D) technique and the principle of cross correlation flow measurement, a new method for flow rate measurement in millimeter-scale pipes was proposed. The research work included two parts. First, a new five-electrode C4D sensor was developed. Second, with two conductivity signals obtained by the developed sensor, the flow rate measurement was implemented by using the principle of cross correlation flow measurement. The experimental results showed that the proposed flow rate measurement method was effective, the developed five-electrode C4D sensor was successful, and the measurement accuracy was satisfactory. In five millimeter-scale pipes with different inner diameters of 0.5, 0.8, 1.8, 3.0 and 3.9 mm respectively, the maximum relative difference of the flow rate measurement between the reference flow rate and the measured flow rate was less than 5%.

    A micromodel system with a pore structure for heterogeneous flow and transport was used to investigate the effect of subgrid transport heterogeneity on redox reaction rates. Hematite reductive dissolution by injecting a reduced form of flavin mononucleotide (FMNH2) at variable flow rates was used as an example to probe the variations of redox reaction rates in different subgrid transport domains. Experiments, pore-scale simulations, and macroscopic modeling were performed to measure and simulate in-situ hematite reduction and to evaluate the scaling behavior of the redox reaction rates from the pore to macroscopic scales. The results indicated that the measured pore-scale rates of hematite reduction were consistent with the predictions from a pore scale reactive transport model. A general trend is that hematite reduction followed reductant transport pathways, starting from the advection-dominated pores toward the interior of diffusion-dominated domains. Two types of diffusion domains were considered in the micromodel: a micropore diffusion domain, which locates inside solid grains or aggregates where reactant transport is limited by diffusion; and a macropore diffusion domain, which locates at wedged, dead-end pore spaces created by the grain-grain contacts. The rate of hematite reduction in the advection-dominated domain was faster than those in the diffusion-controlled domains, and the rate in the macropore diffusion domain was faster than that in the micropore domain. The reduction rates in the advection and macropore diffusion domains increased with increasing flow rate, but were affected by different mechanisms. The rate increase in the advection domain was controlled by the mass action effect as a faster flow supplied more reactants, and the rate increase in the macropore domain was more affected by the rate of mass exchange with the advection domain, which increased with increasing flow rate. The hematite reduction rate in the micropore domain was, however

    The relative quality of a habitat can influence fish consumption, growth, mortality, and production. In order to quantify habitat quality, several authors have combined bioenergetic and foraging models to generate spatially explicit estimates of fish growth rate potential (GRP). However, the capacity of GRP to reflect the spatial distributions of fishes over large areas has not been fully evaluated. We generated landscape scale estimates of steelhead (Oncorhynchus mykiss) GRP throughout Lake Michigan for 1994-1996, and used these estimates to test the hypotheses that GRP is a good predictor of spatial patterns of steelhead catch rates. We used surface temperatures (measured with AVHRR satellite imagery) and acoustically measured steelhead prey densities (alewife, Alosa pseudoharengus) as inputs for the GRP model. Our analyses demonstrate that potential steelhead growth rates in Lake Michigan are highly variable in both space and time. Steelhead GRP tended to increase with latitude, and mean GRP was much higher during September 1995, compared to 1994 and 1996. In addition, our study suggests that landscape scale measures of GRP are not good predictors of steelhead catch rates throughout Lake Michigan, but may provide an index of interannual variation in system-wide habitat quality.

    Previous research has found that Asians (vs. Caucasians) exhibit higher levels of ought and undesired self-discrepancies and prevention focus, all of which have been linked with anxiety. We examined these ethnic differences in the context of acculturation. Participants (N=155) completed two sessions scheduled a week apart. In Session 1, participants completed a computer task to measure self-discrepancy and prevention focus. In Session 2, participants' ought self-discrepancies and closeness to an undesired self were primed. Moderation analyses indicated that Asian participants who were highly assimilated to an Asian culture exhibited higher levels of a prevention focus. Acculturation also had significant moderation effects for affect when self-discrepancies were primed. Our results suggest that interventions based on these systems (i.e., self-system therapy) should consider acculturation when treating diverse individuals. PMID:22339540

    The main purposes of this study are: a) To determine whether the acculturation styles proposed by Berry's model (integration, separation, assimilation and marginalization) can be replicated in a sample of Latin-American immigrant adolescents living in Spain; b) to examine the relationships between acculturation styles and both antisocial behavior and involvement with alcohol. For these purposes, data were collected in a sample of 750 Latin-American immigrants in a number of schools in Galicia and Madrid. Results confirm the existence of the four acculturation strategies, with integration and marginalization as the most and least used, respectively. With respect to the relationships of these styles with antisocial behavior and alcohol use, it was found that adolescents who use the separation strategy show the highest levels of antisocial behavior; conversely, and contrary to expectations, the marginalization group had the lowest levels of antisocial involvement.

    Understanding temporal and spatial evolution of biogeochemical processes at different spatial scales is important (and challenging) for complex, heterogeneous subsurface systems. In this work, we aim to understand the dynamic propagation of uranium bioreduction rates across scales during a field biostimulation experiment at Rifle, Colorado. Acetate was injected as an electron donor to stimulate Fe-reducing bacteria (FeRB) and reduce mobile U(VI) to immobile U(IV). Bicarbonate was co-injected in half of the domain to mobilize sorbed U(VI) to investigate the impact of bicarbonate on the bioreduction of mobile U(VI). We use reactive transport modeling to integrate hydraulic conductivity and aqueous geochemistry data and to quantify bioreduction rates from the local grid block scale (approximately 0.25 meters) to the field scale (10s of meters). The modeling results showed good agreement with the geochemical measurements in the 17 monitoring wells. The good match indicates that the model has captured the dynamics of the system given our conceptual model of an inverse relationship between bioavailable oxidized Fe and permeability, providing constraints for the estimation of aqueous species, mineral precipitates, and biomass. Our results shows that although the local rates varied by more than two orders of magnitude with the biostimulation fronts propagating downstream, the maximum rates remained at the a few 'hot spots' right at the down gradient of the injection wells where Fe(III), U(VI), and FeRB were at their maximum. These local rates dominated the ';field-scale' rates (10's of m2). At particular locations, the 'hot moments' with maximum bioreduction rates positively corresponded to their distance from the wells. Although bicarbonate injection enhanced the local bioreduction rates near the injection wells by a maximum of 41.9%, its effect at the field-scale was limited to a maximum of 15.7%, with majority of the domain unaffected. The field-scale rates calculated

    OBJECTIVES Acculturation has been shown to positively and negatively affect Latino health. Little research investigates the overlap between acculturation and the different types of relationship violence among Latino youth and most research in this area predominantly involves Mexican-American samples. The current study examined associations between indices of acculturation (language use at home, chosen survey language, and nativity) and relationship physical violence and sexual coercion, both received and delivered, among predominantly Dominican and Puerto Rican adolescents from New York City. METHODS From 2006-2007, 1,454 adolescents aged 13-21 years in New York City completed an anonymous survey that included the Conflict in Adolescent Relationships Inventory which estimates experiences of physical violence and sexual coercion, both received and delivered, in the previous year. This analysis includes bivariate and multivariate methods to test the associations between language use at home, chosen survey language, and nativity with the different types of relationship violence. RESULTS Among females, there is a significant association between language use at home and overall level of acculturation with delivering and receiving relationship physical violence; however, we did not find this association in delivering and receiving relationship sexual coercion. We found no association between acculturation and any type of relationship violence among males. CONCLUSIONS Among Latina females, language spoken at home is an indicator of other protective factors of physical relationship violence. Future research in this area should explore the potential protective factors surrounding relationship violence among Latina females of various subgroups using comprehensive measures of acculturation, household composition and family engagement.

    We estimated survival rates of Swainson's Thrush, a common, neotropical, migratory landbird, at multiple spatial scales, using data collected in the western USA from the Monitoring Avian Productivity and Survivorship Programme. We evaluated statistical power to detect spatially heterogeneous survival rates and exponentially declining survival rates among spatial scales with simulated populations parameterized from results of the Swainson's Thrush analyses. Models describing survival rates as constant across large spatial scales did not fit the data. The model we chose as most appropriate to describe survival rates of Swainson's Thrush allowed survival rates to vary among Physiographic Provinces, included a separate parameter for the probability that a newly captured bird is a resident individual in the study population, and constrained capture probability to be constant across all stations. Estimated annual survival rates under this model varied from 0.42 to 0.75 among Provinces. The coefficient of variation of survival estimates ranged from 5.8 to 20% among Physiographic Provinces. Statistical power to detect exponentially declining trends was fairly low for small spatial scales, although large annual declines (3% of previous year's rate) were likely to be detected when monitoring was conducted for long periods of time (e.g. 20 years). Although our simulations and field results are based on only four years of date from a limited number and distribution of stations, it is likely that they illustrate genuine difficulties inherent to broadscale efforts to monitor survival rates of territorial landbirds. In particular, our results suggest that more attention needs to be paid to sampling schemes of monitoring programmes particularly regarding the trade-off between precison and potential bias o parameter estimates at varying spatial scales.

    Study 1 examined the reliability of the ratings assigned to the performance of five sign-and-symptom items drawn from tests of motor impairment in Parkinson's disease. Patients with Parkinson's disease of varying severity performed gait, rising from chair, and hand function items. Video recordings of these performances were rated by a large sample of experienced and inexperienced neurologists and by psychology undergraduates, using a four point scale. Inter-rater reliability was moderately high, being higher for gait than hand function items. Clinical experience proved to have no systematic effect on ratings or their reliability. The idiosyncrasy of particular performances was a major source of unreliable ratings. Study 2 examined the intercorrelation of several standard rating scales, comprised of sign-and-symptom items as well as activities of daily living. The correlation between scales was high, ranging from 0.70 to 0.83, despite considerable differences in item composition. Inter-item correlations showed that the internal cohesion of the tests was high, especially for the self-care scale. Regression analysis showed that the relationship between the scales could be efficiently captured by a small selection of test items, allowing the construction of a much briefer test. PMID:2010754

    This study investigates associations between immigration and acculturation with sexual assault among a large, representative sample of high school girls. The analysis utilized data from the Massachusetts Youth Risk Behavior Surveys conducted in 1999, 2001, and 2003 (N = 5,919). Adjusted logistic regression analyses were conducted among the full sample and a sexually active subsample. Being an immigrant was associated with recurring sexual assault victimization; this effect was not consistent across age and racial/ethnic groups. Immigrant status conferred risk among adolescent girls aged 15 and younger, Black adolescent girls, and sexually active Hispanic girls. No differences were detected in sexual assault victimization based on acculturation. PMID:17478674

    Forest managers sometimes harvest burned trees after wildfires to realize economic value, reduce fuel loads, or achieve other operational goals. This logging can be controversial because some ecosystem effects are negative, yet the potential impacts on erosion rates have not been clearly identified. Our objectives were to quantify hillslope-scale erosion rates and compare the hillslope erosion rates to rates from larger (swale) and smaller (rill) scales. Soil characteristics, vegetative regrowth, and erosion rates were measured in logged areas and unlogged controls at seven severely burned sites in the western US. One site had replicated measurements at all three scales, five sites had only hillslope or swale scale measurements, and one site had only rill measurements. Erosion rates from hillslopes (70-170 m2) and swales (0.1-2.6 ha) were measured with sediment fences. Rill erosion rates were measured with rill experiments, where water was applied to a hillslope at five flow rates for 12 min each; water samples were collected at a point 9 m downslope. At the hillslope scale the passage of heavy logging equipment reduced soil water repellency, compacted the soil, reduced vegetative regrowth rates, and generally increased erosion rates by one or two orders of magnitude relative to the controls. The rill experiments also showed greater rates of rill incision and erosion from the areas disturbed by heavy logging equipment relative to the controls. At the swale scale erosion rates were higher in the logged areas than the controls when measurements were replicated and simultaneous but there was no detectable change in the other study areas. Overall, the absolute erosion rates from both logged and unlogged areas tended to decline over time while the relative difference in erosion tended to increase due to the slower vegetative recovery in the more heavily disturbed areas. The potential adverse effects of salvage logging can be minimized by reducing compaction and

    The purpose of this study was to develop the laboratory-scale melter (LSM) as a quick and inexpensive method to determine the processing rate of various waste glass slurry feeds. The LSM uses a 3 or 4 in. diameter-fused quartz crucible with feed and off-gas ports on top. This LSM setup allows cold-cap formation above the molten glass to be directly monitored to obtain a steady-state melting rate of the waste glass feeds. The melting rate data from extensive scaled-melter tests with Hanford Site high-level wastes performed for the Hanford Tank Waste Treatment and Immobilization Plant have been compiled. Preliminary empirical model that expresses the melting rate as a function of bubbling rate and glass yield were developed from the compiled database. The two waste glass feeds with most melter run data were selected for detailed evaluation and model development and for the LSM tests so the melting rates obtained from LSM tests can be compared with those from scaled-melter tests. The present LSM results suggest the LSM setup can be used to determine the glass production rates for the development of new glass compositions or feed makeups that are designed to increase the processing rate of the slurry feeds.

  15. Relationships between rating scales, question stem wording, and community responses to railway noise

    2004-10-01

    Two series of social surveys on community responses to railway noise were carried out in Japan to evaluate the relationships between two verbal scales and a numeric scale, and those among four base descriptors. In the first survey, two types of questionnaires were prepared in which a 0-10- point numeric scale was used in combination with either a four-point or a five-point verbal scale. The key questions concerned annoyance, activity disturbance and related effects caused by railway noise. Community responses were compared on the basis of the dose-response relationships. Regarding the percentages of respondents who answered, "highly annoyed," it was found that there were no systematic differences between the two verbal scales. It was also found that the extent of noise annoyance rated on the four-point or five-point verbal scale corresponded with that rated on the 11-point numeric scale by percentages of scale steps. In the second survey, four types of questionnaires were prepared, each using one of the four base descriptors. Community responses to general noise annoyance among the four base descriptors were compared. No systematic differences were found among the four base descriptors.

  17. The association between acculturation and dietary patterns of South Asian immigrants.

    2014-01-01

    Dietary acculturation, specifically the adoption of western dietary habits, may result in adverse health effects such as obesity and type 2 diabetes. Therefore, it is necessary to explore the role of acculturation in dietary patterns as well as awareness and knowledge of healthy nutrition among South Asian immigrants. This is an especially important population to target as South Asians have higher prevalence rates of type 2 diabetes and cardiovascular disease, which may be magnified with immigration. The current investigation is a sub-study of the Multi-Cultural Community Health Assessment Trial (M-CHAT). There were 207 participants of South Asian origin included in the initial study, 129 were born outside of Canada and had immigrated after the age of 18. The length of residence in Canada was used as a marker for acculturation. A questionnaire addressing perceived changes in dietary patterns, food preparation, and nutrition knowledge and awareness since immigration was used to assess dietary practices. The association between length of residence and variables related to perceived changes in dietary patterns was explored with Spearman correlation and significant associations were subsequently analyzed with ordinal logistic regression analysis adjusted for age, sex, education and body mass index. South Asian immigrants in Canada reported a variety of positive dietary practices, including an increased consumption of fruits and vegetables and an improvement in food preparation (including an increase in grilling and a decrease in deep frying when cooking). However, there was a reported increase in the consumption of convenience foods, sugar-sweetened beverages, red meat and in dining out. South Asian immigrants in Canada reported a variety of positive dietary practices including an improvement in food preparation. Future health promotion strategies should encourage cultural sensitivity in efforts to reduce the consumption of sugar-sweetened beverage, convenience foods

  18. Up-Scaling Geochemical Reaction Rates for Carbon Dioxide (CO2) in Deep Saline Aquifers

    Lindquist, W Brent

    2009-03-03

    The overall goal of the project was to bridge the gap between our knowledge of small-scale geochemical reaction rates and reaction rates meaningful for modeling transport at core scales. The working hypothesis was that reaction rates, determined from laboratory measurements based upon reactions typically conducted in well mixed batch reactors using pulverized reactive media may be significantly changed in in situ porous media flow due to rock microstructure heterogeneity. Specifically we hypothesized that, generally, reactive mineral surfaces are not uniformly accessible to reactive fluids due to the random deposition of mineral grains and to the variation in flow rates within a pore network. Expected bulk reaction rates would therefore have to be correctly up-scaled to reflect such heterogeneity. The specific objective was to develop a computational tool that integrates existing measurement capabilities with pore-scale network models of fluid flow and reactive transport. The existing measurement capabilities to be integrated consisted of (a) pore space morphology, (b) rock mineralogy, and (c) geochemical reaction rates. The objective was accomplished by: (1) characterizing sedimentary sandstone rock morphology using X-ray computed microtomography, (2) mapping rock mineralogy using back-scattered electron microscopy (BSE), X-ray dispersive spectroscopy (EDX) and CMT, (3) characterizing pore-accessible reactive mineral surface area, and (4) creating network models to model acidic CO{sub 2} saturated brine injection into the sandstone rock samples.

    2003-03-01

    The purpose of the present study was to develop the Chronic Obstructive Pulmonary Disease (COPD) Activity Rating Scale (CARS) to measure life-related activity in patients with COPD, and to confirm its reliability and constructive validity in a factorial structure model. The subjects consisted of 114 patients with COPD. An 88-item life-related activity list, generated previously from a literature review, was administered. The secondary structural model consisted of four factors with 12 items. The results of the confirmatory factor analysis by structural equation modeling showed the fit criteria to be statistically significant. The internal consistency of the 12 items was highly reliable (Cronbach's alpha = 0.924). The CARS score was correlated with pulmonary function tests, breathlessness, and the health-related quality of life (QOL) scales in Pearson correlation coefficient. The results suggest that the COPD Activity Rating Scale is a valid scale for the assessment of life-related activity in patients with COPD. PMID:12603718

    In this paper, we investigate scaling relations between star formation rates and molecular gas masses for both local Galactic clouds and a sample of external galaxies. We specifically consider relations between the star formation rates and measurements of dense, as well as total, molecular gas masses. We argue that there is a fundamental empirical scaling relation that directly connects the local star formation process with that operating globally within galaxies. Specifically, the total star formation rate in a molecular cloud or galaxy is linearly proportional to the mass of dense gas within the cloud or galaxy. This simple relation, first documented in previous studies, holds over a span of mass covering nearly nine orders of magnitude and indicates that the rate of star formation is directly controlled by the amount of dense molecular gas that can be assembled within a star formation complex. We further show that the star formation rates and total molecular masses, characterizing both local clouds and galaxies, are correlated over similarly large scales of mass and can be described by a family of linear star formation scaling laws, parameterized by f{sub DG}, the fraction of dense gas contained within the clouds or galaxies. That is, the underlying star formation scaling law is always linear for clouds and galaxies with the same dense gas fraction. These considerations provide a single unified framework for understanding the relation between the standard (nonlinear) extragalactic Schmidt-Kennicutt scaling law, that is typically derived from CO observations of the gas, and the linear star formation scaling law derived from HCN observations of the dense gas.

  2. [Assessment of the distance between categories in rating scales by using the item response model].

    PubMed

    Wakita, Takafumi

    2004-10-01

    This study aimed to assess the distance between adjacent categories of rating scales. It is common practice to treat ordinal variables as interval-scaled variables in the analysis of rating scales. Strictly speaking, however, ordinal scale data should be treated as such, since there is little reason and assurance that they are equivalent to interval variables. In view of this practice, this study proposes a method to assess the interval of rating scales, and analyzes empirical data in order to examine the results obtained by the method. This method is based upon the generalized partial credit model which is one of item response theory (IRT) models. The experiment was carried out on two data sets that differed only on the verbal phrasing of the rating. Main results of the study were: 1) the difference in item content (positive or negative) affects the width of a neutral category; and 2) the distance between categories differs significantly reflecting the difference in verbal phrasing.

    2011-01-01

    Exposure to obesogenic environments in the U.S. may foster development of overweight in immigrants with greater acculturation. Few studies document mechanisms of the acculturation process from immigrants’ own perspectives or describe implications on the children of immigrants. Focus groups and in-depth interviews were conducted with immigrant Latina mothers (N=51) examining mothers’ beliefs, attitudes and practices related to early child feeding and weight. Focus group participants completing the Marin Acculturation Scale more closely identified with Latino culture, although the mean score (2.04, sd=0.59) was close to “bicultural”. Analysis revealed seven themes when mothers compared lifestyles between their native countries and the U.S., related to changes in 1) diet, perceived food quality and availability, 2) food and eating practices, 3) breastfeeding practices, 4) beliefs about food, child feeding and weight status, 5) weight status of mothers and children, 6) physical activity and sedentary lifestyles, and 7) social isolation and support.

    We approach heart interbeat rate by observing the evolution of its stability on scales and time, using tools for the analysis of frequency standards. In particular, we employ the dynamic Allan variance, which is used to characterize the time-varying stability of an atomic clock, to analyze heart interbeat time series for normal subjects and patients with congestive heart failure (CHF). Our stability analysis shows that healthy dynamics is characterized by at least two stability regions along different scales. In contrast, diseased patients exhibit at least three different stability regions; over short scales the fluctuations resembled white-noise behavior whereas for large scales a drift is observed. The inflection points delimiting the first two stability regions for both groups are located around the same scales. Moreover, we find that CHF patients show lower variation of the stability in time than healthy subjects.

    2016-01-01

    This article provides an analysis of novel topics emerging in recent years in research on Latino immigrants, acculturation, and health. In the past ten years, the number of studies assessing new ways to conceptualize and understand how acculturation-related processes may influence health has grown. These new frameworks draw from integrative approaches testing new ground to acknowledge the fundamental role of context and policy. We classify the emerging body of evidence according to themes that we identify as promising directions--intrapersonal, interpersonal, social environmental, community, political, and global contexts, cross-cutting themes in life course and developmental approaches, and segmented assimilation--and discuss the challenges and opportunities each theme presents. This body of work, which considers acculturation in context, points to the emergence of a new wave of research that holds great promise in driving forward the study of Latino immigrants, acculturation, and health. We provide suggestions to further advance the ideologic and methodologic rigor of this new wave. PMID:26735431

    Sam, David L; Berry, John W

    2010-07-01

    In cross-cultural psychology, one of the major sources of the development and display of human behavior is the contact between cultural populations. Such intercultural contact results in both cultural and psychological changes. At the cultural level, collective activities and social institutions become altered, and at the psychological level, there are changes in an individual's daily behavioral repertoire and sometimes in experienced stress. The two most common research findings at the individual level are that there are large variations in how people acculturate and in how well they adapt to this process. Variations in ways of acculturating have become known by the terms integration, assimilation, separation, and marginalization. Two variations in adaptation have been identified, involving psychological well-being and sociocultural competence. One important finding is that there are relationships between how individuals acculturate and how well they adapt: Often those who integrate (defined as being engaged in both their heritage culture and in the larger society) are better adapted than those who acculturate by orienting themselves to one or the other culture (by way of assimilation or separation) or to neither culture (marginalization). Implications of these findings for policy and program development and for future research are presented. PMID:26162193

    Ryu, Jong Kwan; Jeon, Jin Yong

    2005-09-01

    In this study, 5-point and 7-point verbal noise annoyance scales were developed. The 5-point annoyance scale for outside environmental noise was developed from a survey conducted in four Korean cities. An auditory experiment using residential noises such as airborne, bathroom drainage, and traffic noises was conducted to compare the effectiveness of the 5-point and 7-point scales for rating residential indoor noise. Result showed that the 7-point scale yielded more detailed responses to indoor residential noise. In addition, auditory experiments were conducted to develop a noise annoyance scale for the classification of common residential noises. The modifiers used in the scales were selected according to the method proposed by ICBEN (International Commission on the Biological 12Effect of Noise) Team 6. As a result, the difference between the intensity of 21 modifiers investigated in the survey and the auditory experiment was very small. It was also found that the intensity of the selected modifiers in the 7-point noise annoyance scale was highly correlated with noise levels, and that the intensity difference between each pair of successive levels in the 7-point annoyance scale was almost identical.

  15. Acculturation and Its Discontents: A Case for Bringing Anthropology Back into the Conversation

    Guarnaccia, Peter J.; Hausmann-Stabile, Carolina

    2016-01-01

    Anthropologists’ contribution to the study of cultural change is urgent in light of the increasing number of people of different backgrounds who are migrating around the globe and settling in new communities, and the opportunities and challenges that come along with that process. By examining the anthropological literature on acculturation going back to the 1936 Memorandum by Redfield, Linton and Herskovits, this paper reviews and assesses the discipline’s perspective on acculturation, and lays out the case for why it is critical for anthropologists to re-engage the concept. Although other disciplines, particularly psychology and sociology, have dominated the field of acculturation research more recently, they mostly have done so with a narrow focus. While it is important to acknowledge the pitfalls of anthropology’s past study of acculturation, there are important features of the acculturation construct that continue to be relevant. Among these are the study of acculturation as a process that is multidimensional; the investigation of how different kinds of power affect the acculturation process; the impacts of attitudes, actions and policies of the receiving group on how acculturation proceeds; the role of “real history” in understanding processes of acculturation; and the global perspective on these processes. We suggest ways in which anthropologists can reignite the field of acculturation research by engaging with Redfield, Linton and Herskovits’ framework and subsequent anthropological literature.

  16. Allometric scaling of foraging rate with trail dimensions in leaf-cutting ants

    PubMed Central

    Bruce, Andrew I.; Burd, Martin

    2012-01-01

    Leaf-cutting ants (Atta spp.) create physical pathways to support the transport of resources on which colony growth and reproduction depend. We determined the scaling relationship between the rate of resource acquisition and the size of the trail system and foraging workforce for 18 colonies of Atta colombica and Atta cephalotes. We examined conventional power-law scaling patterns, but did so in a multivariate analysis that reveals the simultaneous effects of forager number, trail length and trail width. Foraging rate (number of resource-laden ants returning to the nest per unit time) scaled at the 0.93 power of worker numbers, the –1.02 power of total trail length and the 0.65 power of trail width. These scaling exponents indicate that individual performance declines only slightly as more foragers are recruited to the workforce, but that trail length imposes a severe penalty on the foraging rate. A model of mass traffic flow predicts the allometric patterns for workforce and trail length, although the effect of trail width is unexpected and points to the importance of the little-known mechanisms that regulate a colony's investment in trail clearance. These results provide a point of comparison for the role that resource flows may play in allometric scaling patterns in other transport-dependent entities, such as human cities. PMID:22337696

    The aim of this study was to develop self-report and clinician-rated versions of an insight scale that would be easy to administer, sensitive to small changes, and inclusive of the core dimensions of clinical insight into psychosis. Ten-item self-report (VAGUS-SR) and five-item clinician-rated (VAGUS-CR) scales were designed to measure the dimensions of insight into psychosis and evaluated in 215 and 140 participants, respectively (www.vagusonline.com). Tests of reliability and validity were performed. Both the VAGUS-SR and VAGUS-CR showed good internal consistency and reliability. They demonstrated good convergent and discriminant validity. Both versions were strongly correlated with one another and with the Schedule for the Assessment of Insight and Birchwood Insight Scale. Exploratory factor analyses identified three possible latent components of insight. The VAGUS-CR and VAGUS-SR are valid, reliable and easy to administer. They are build on previous insight scales with separate clinician-rated and self-report versions. The VAGUS-SR exhibited a multidimensional factor structure. Using a 10-point Likert scale for each item, the VAGUS has the capacity to detect small, temporally sensitive changes in insight, which is essential for intervention studies with neurostimulation or rapidly acting medications.

    2009-09-01

    The aim of this study was to detect changes in the fractal scaling behavior of heart rate and speed fluctuations when the average runner’s speed decreased with fatigue. Scaling analysis in heart rate (HR) and speed (S) dynamics of marathon runners was performed using the detrended fluctuation analysis (DFA) and the wavelet based structure function. We considered both: the short-range ( α1) and the long-range ( α2) scaling exponents for the DFA method separated by a change-point, n0=64=5.3 min (box length), the same for all the races. The variability of HR and S decreased in the second part of the marathon race, while the cardiac cost time series (i.e. the number of cardiac beats per meter) increased due to the decreasing speed behavior. The scaling exponents α1 and α2 of HR and α1 of S, increased during the race ( p<0.01) as did the HR wavelet scaling exponent ( τ). These findings provide evidence of the significant effect of fatigue induced by long exercise on the heart rate and speed variability.

  14. An Examination of the Structure and Construct Validity of the Wender Utah Rating Scale.

    PubMed

    Stanton, Kasey; Watson, David

    2016-01-01

    The Wender Utah Rating Scale (Ward, Wender, & Reimherr, 1993 ) has been widely used in adult attention-deficit/hyperactivity disorder (ADHD) research to assess childhood symptoms retrospectively, but little research has examined its factor structure and specificity in predicting ADHD versus other psychopathology. Consequently, this study had 2 goals: (a) to examine the Wender Utah Rating Scale's structure, and (b) to explicate the construct validity of this measure by relating factors from our structural analyses to other ADHD, psychopathology, and personality measures. Structural analyses in an adult community sample (N = 294) yielded a 3-factor structure of aggression (e.g., angry), internalizing distress (e.g., depressed), and academic difficulties (e.g., underachiever). Correlational and regression analyses indicated that these factors failed to display specificity in their associations with ADHD versus other psychopathology. Aggression and internalizing distress associated most strongly with indicators of externalizing (e.g., ill temper, manipulativeness) and internalizing psychopathology (e.g., depression, anxiety), respectively. Academic difficulties associated most strongly with ADHD symptoms, but these relations were relatively weak. Taken together, these findings raise concerns about the Wender Utah Rating Scale's construct validity, although additional longitudinal research is needed to clarify to what extent the Wender Utah Rating Scale validly assesses childhood ADHD symptoms.

    Harkness, D; Swenson, M; Madsen-Hampton, K; Hale, R

    2001-01-01

    This investigation examined the reliability and validity of a rating scale for codependency in substance abuse treatment. The investigators developed an example-anchored rating scale to operationalize codependency as substance abuse counselors construe it in practice, and recruited 27 counselors for a counterbalanced multiple-treatment experiment. Counselors were randomly assigned to one of four continuing education workshops for rating-scale training, and asked to evaluate codependency in five videotaped cases. Semistructured case interviews were videotaped with a male and a female from five adult populations to vary the gender and codependency of cases: (1) outpatients in treatment for addiction, (2) outpatient spouses, (3) members of Codependents Anonymous, (4) United States Bureau of Land Management smoke jumpers, and (5) college students majoring in business or economics. To control for gender effects, one workshop presented male cases, one workshop presented female cases, and two workshops presented cases of both genders. To control for order effects, the assignment of videotapes to workshops was randomized to counterbalance the order in which counselors viewed them. The findings suggest that the rating scale yields reliable and valid evaluations of codependency without appreciable gender bias. PMID:11476263

  16. Erosive Augmentation of Solid Propellant Burning Rate: Motor Size Scaling Effect

    NASA Technical Reports Server (NTRS)

    Strand, L. D.; Cohen, Norman S.

    1990-01-01

    Two different independent variable forms, a difference form and a ratio form, were investigated for correlating the normalized magnitude of the measured erosive burning rate augmentation above the threshold in terms of the amount that the driving parameter (mass flux or Reynolds number) exceeds the threshold value for erosive augmentation at the test condition. The latter was calculated from the previously determined threshold correlation. Either variable form provided a correlation for each of the two motor size data bases individually. However, the data showed a motor size effect, supporting the general observation that the magnitude of erosive burning rate augmentation is reduced for larger rocket motors. For both independent variable forms, the required motor size scaling was attained by including the motor port radius raised to a power in the independent parameter. A boundary layer theory analysis confirmed the experimental finding, but showed that the magnitude of the scale effect is itself dependent upon scale, tending to diminish with increasing motor size.

    2013-01-01

    The question of how the scaling of metabolic rate with body mass (M) is achieved in animals is unresolved. Here, we tested the cell metabolism hypothesis and the organ size hypothesis by assessing the mass scaling of the resting metabolic rate (RMR), maximum metabolic rate (MMR), erythrocyte size, and the masses of metabolically active organs in the crucian carp (Carassius auratus). The M of the crucian carp ranged from 4.5 to 323.9 g, representing an approximately 72-fold difference. The RMR and MMR increased with M according to the allometric equations RMR = 0.212M0.776 and MMR = 0.753M0.785. The scaling exponents for RMR (br) and MMR (bm) obtained in crucian carp were close to each other. Thus, the factorial aerobic scope remained almost constant with increasing M. Although erythrocyte size was negatively correlated with both mass-specific RMR and absolute RMR adjusted to M, it and all other hematological parameters showed no significant relationship with M. These data demonstrate that the cell metabolism hypothesis does not describe metabolic scaling in the crucian carp, suggesting that erythrocyte size may not represent the general size of other cell types in this fish and the metabolic activity of cells may decrease as fish grows. The mass scaling exponents of active organs was lower than 1 while that of inactive organs was greater than 1, which suggests that the mass scaling of the RMR can be partly due to variance in the proportion of active/inactive organs in crucian carp. Furthermore, our results provide additional evidence supporting the correlation between locomotor capacity and metabolic scaling. PMID:24376588

    To investigate the inter-rater reliability and validity of the Neurobehavioural Rating Scale at various stages of recovery after hospitalisation for closed head injury, we studied 101 head trauma patients who had no antecedent neuropsychiatric disorder. The results demonstrated satisfactory inter-rater reliability and showed that the Neurobehavioural Rating Scale reflects both the severity and chronicity of closed head injury. A principal components analysis revealed four factors which were differentially related to severity of head injury and the presence of a frontal lobe mass lesion. Although our findings provide support for utilising clinical ratings of behaviour to investigate sequelae of head injury, extension of this technique to other settings is necessary to evaluate the distinctiveness of the neurobehavioural profile of closed head injury as compared with other aetiologies of brain damage.

    2015-06-01

    A fundamental understanding of the microstructure effects on the defect evolution at the atomic resolution and the related contribution to plasticity at the macro-scales is needed to obtain a reliable performance of metallic materials in extreme environments. Large-scale molecular dynamics simulations are carried out to characterize the dynamic evolution of defect/damage structures during the deformation and failure behavior of HCP (Mg, Ti) metallic systems (single crystal and nanocrystalline at high strain rates as well as under shock loading conditions. The evolution of various types of dislocations, twins, faults, etc. and the related deformation and failure response (nucleation and growth of voids/cracks) will be discussed. The effects of strain rates on relationships between the microstructure and the strength of these materials at high strain rates and the underlying micromechanisms related to deformation and failure will be discussed.

    2015-01-01

    This study was a preliminary examination of the psychometric properties of a newly developed Spanish translated version of the Gifted Rating Scales-School Form (GRS-S). Data was collected from elementary and middle schools in northeastern Puerto Rico. Thirty teachers independently rated 153 students using the GRS-S Spanish Form. Results indicated strong internal consistency for teacher ratings with alphas ranging from .98 to .99. Intercorrelations between scales are moderate to strong, ranging from .88 to .97. Factor testing of two separate models supported a six factor model proposed by authors of the GRS-S. Results provided initial support for the GRS-S Spanish translated version as a reliable and potentially useful screening measure to assist in the identification of island Puerto Rican gifted students.

    Objective Our study aimed to measure inter-rater and test-retest reliability, concurrent and convergent validity, and factor solutions of the Korean version of the Clinical Language Disorder Rating Scale (CLANG). Methods The Korean version of the CLANG for assessing thought, language, and communication, the Brief Psychiatric Rating Scale, Young Mania Rating Scale, and Calgary Depression Scale for Schizophrenia were used to evaluate language disorder, formal thought disorder, positive and negative symptoms, manic symptoms, and depressive symptoms, respectively, in 167 hospitalized patients with schizophrenia. The factor solution was obtained by the direct oblimin method. A receiver operating characteristic curve was used to find the optimal cut-off score for discriminating schizophrenia patients with and without disorganized speech. Results Inter-rater reliability was considered moderate (intraclass coefficient=0.67, F=3.30, p=0.04), and test-retest reliability was considered high (r=0.94, p<0.001). Five factors, namely, pragmatics, disclosure, production, prosody, and association, were identified. An optimal cut-off score of 7 points with 84.5% sensitivity and 81.7% specificity was proposed for distinguishing schizophrenia patients with and without disorganized speech. Conclusion Our findings suggest that the Korean version of the CLANG is a promising tool for evaluating language disorder in patients with schizophrenia. PMID:26792040

  12. Scaling of the hysteresis in the glass transition of glycerol with the temperature scanning rate

    2011-03-01

    By measuring the dependences of the temperature-dependent primary ("alpha") dielectric relaxation time behavior on the temperature scanning rate for the glass-forming glycerol, we study the scaling of hysteresis at the glass transition in glycerol. Based on the Vogel-Fulcher-Tammann (VFT) expression and the Angell's fragility concept, notable correlations of the systematic kinetic fragility, and of the hysteresis effect in the vitrification/fusion "alpha"-relaxation process of glycerol, with the temperature scanning rate, were reasonably analyzed and discussed. It was observed that the kinetic fragility m and the apparent glass-transition temperature hysteresis width Δ T_g^a, respectively, scaled the temperature scanning rate q as m ≈ αmq-γ and Δ T_g^a ≈ A0 + αqβ, at which the exponents, γ and β, were suggested to be characteristic of the resistance to the structure change or fragility change of the system during the glass transition. The observed scaling laws are quite similar to the scaling power law for the thermal hysteresis in the first-order phase transition (FOPT) of solids, providing a significant insight into the hysteresis effect in the glass transition of the glass-forming liquids.

    A remarkable high fracture toughness is sometimes observed for interfaces between materials with a large elastic mismatch, which is reported to be caused by the fibrillar microstructure appearing in the fracture process zone. In this work, this fibrillation mechanism is investigated further to investigate how this mechanism is dissipating energy. For that purpose, thermoplastic urethane (TPU)-copper interfaces are delaminated at various rates in a peel test experimental setup. The fracture process zone is visualized in situ at the meso-scale using optical microscopy and at the micro-scale using Environmental Scanning Electron Microscopy (ESEM). It is shown that the geometry of the fracture process zone is insensitive to the delamination rate, while the interface traction scales logarithmically with the rate. This research has revealed that, the interface roughness is shown to be pivotal in initiating the fibrillation delamination process, which facilitates the high fracture toughness. The multi-scale experimental approach identified two mechanisms responsible for this high fracture toughness. Namely, the viscous dissipation of the TPU at the high strain levels occurring in the fibrils and the loss of stored elastic energy which is disjointed from the propagation due to the size of the process zone.

    Attention deficit hyperactivity disorder (ADHD) in adults is increasingly recognized as a clinically important syndrome. The aim of this study was to evaluate the psychometric performance of a new scale for adult ADHD based on the widely used Symptom Checklist 90 Revised (SCL-90-R). Scale performance was assessed in a clinical study including 100 ADHD patients and 65 opiate-dependent patient controls, and in the Zurich study, an epidemiological age cohort followed over 30 years of adult life. Assessments included a ROC analysis of sensitivity and specificity, internal consistency, test-retest reliability, external validity and measurement invariance over nine testing occasions. The new scale showed a sensitivity and specificity of 75 and 54%, respectively, internal consistency over 0.8 (McDonald's omega, Cronbach's alpha), one-year test-retest reliabilities over 0.7, statistically significant and substantial correlations with two other validated self-rating scales of adult ADHD (R = 0.5 and 0.66, respectively), and an acceptable degree of longitudinal stability (i.e., measurement invariance). The proposed scale must be further evaluated, but these preliminary results indicate it could be a useful rating instrument for adult ADHD in situations where SCL-90-R data, but no specific ADHD assessment, are available, such as in retrospective data analysis or in prospective studies with limited methodical resources.

  15. Strain rate, temperature and representative length scale influence on plasticity and yield stress in copper

    Shock compression of materials constitutes a complex process involving high strain rates, elevated temperatures and compression of the lattice. Materials properties are greatly affected by temperature, the representative length scale and the strain rate of the deformation. Experimentally, it is difficult to study the dynamic microscopic mechanisms that affect materials properties following high intensity shock loading, but they can be investigated using molecular dynamics (MD) simulations. Moreover, MD allows a better control over some parameters. We are using MD simulations to study the effect of the strain rate, representative length scale and temperature on the properties of metals during compression. A half-million-atom Cu sample is subjected to strain rates ranging from 10{sup 7} s{sup -1} to 10{sup 12} s{sup -1} at different temperatures ranging from 50K to 1500K. Single crystals as well as polycrystals are investigated. Plasticity mechanisms as well as the evolution of the micro- and macro-yield stress are observed. Our results show that the yield stress increases with increasing strain rate and decreasing temperature. We also show that the strain rate at which the transition between constant and increasing yield stress as a function of the temperature occurs increases with increasing temperature. Calculations at different grain sizes will give an insight into the grain size effect on the plasticity mechanisms and the yield stress.

    Survivorship is a primary demographic parameter affecting population dynamics, and thus trends in species abundance. The Monitoring Avian Productivity and Survivorship (MAPS) program is a cooperative effort designed to monitor landbird demographic parameters. A principle goal of MAPS is to estimate annual survivorship and identify spatial patterns and temporal trends in these rates. We evaluated hypotheses of spatial patterns in survival rates among a collection of neighboring sampling sites, such as within national forests, among biogeographic provinces, and between breeding populations that winter in either Central or South America, and compared these geographic-specific models to a model of a common survival rate among all sampling sites. We used data collected during 1992-1995 from Swainson's Thrush (Cathorus ustulatus) populations in the western region of the United States. We evaluated the ability to detect spatial and temporal patterns of survivorship with simulated data. We found weak evidence of spatial differences in survival rates at the local scale of 'location,' which typically contained 3 mist-netting stations. There was little evidence of differences in survival rates among biogeographic provinces or between populations that winter in either Central or South America. When data were pooled for a regional estimate of survivorship, the percent relative bias due to pooling 'locations' was 12 years of monitoring. Detection of spatial patterns and temporal trends in survival rates from local to regional scales will provide important information for management and future research directed toward conservation of landbirds.

    The aim of this study is the normalization of the Wender Utah rating scale which is used to detect adults with Attention-Deficit and Hyperactivity Disorder (ADHD). Available sampling method was used to choose 400 parents of children (200 parents of children with ADHD as compared to 200 parents of normal children). Wender Utah rating scale, which has been designed to diagnose ADHD in adults, is filled out by each of the parents to most accurately diagnose of ADHD in parents. Wender Utah rating scale was divided into 6 sub scales which consist of dysthymia, oppositional defiant disorder; school work problems, conduct disorder, anxiety, and ADHD were analyzed with exploratory factor analysis method. The value of (Kaiser-Meyer-Olkin) KMO was 86.5% for dysthymia, 86.9% for oppositional defiant disorder, 77.5% for school related problems, 90.9% for conduct disorder, 79.6% for anxiety and 93.5% for Attention deficit/hyperactivity disorder, also the chi square value based on Bartlett's Test was 2242.947 for dysthymia, 2239.112 for oppositional defiant disorder, 1221.917 for school work problems, 5031.511 for conduct, 1421.1 for anxiety, and 7644.122 for ADHD. Since mentioned values were larger than the chi square critical values (P<0.05), it found that the factor correlation matrix is appropriate for factor analysis. Based on the findings, we can conclude that Wender Utah rating scale can be appropriately used for predicting dysthymia, oppositional defiant disorder, school work problems, conduct disorder, anxiety, in adults with ADHD.

    2012-10-01

    Health disparities among Latinos have been associated with acculturation, but there is a lack of consensus about how acculturation variables translate into health beliefs that can be used to target attitude and behavior change interventions. Transcripts from three qualitative studies including 64 Latino immigrant adults were analyzed through inductive reasoning to assess relationships between more or less acculturated attitudes, and demographic variables. In the three topic areas of gender roles, sex education, and seeking professional help, attitudes ranged from conservative (less acculturated) to liberal (more acculturated), but did not seem associated with age, education or years in the United States. When dealing with specific health topics, it is not possible to infer specific attitudes, strength of attitudes or level of acculturation of intervention recipients. To develop sound, culturally competent interventions, it is necessary to assess the targets' beliefs and attitudes and tailor messages in specific contexts. PMID:22350810

    The present study examined the relationship between Berry’s acculturation typology and HIV risk behaviors and whether family functioning mediated any such effects. A total of 235 high risk Hispanic adolescents were categorized into one of Berry’s four acculturation typologies through the use of cut-off scores on measures of Hispanicism and Americanism. Structural equation modeling was used to examine the effects of acculturation typology on HIV risk behaviors and the indirect effects of acculturation typology on HIV risk behaviors through family functioning. Acculturation typology was related to HIV risk behaviors. Family functioning partially mediated the effects of acculturation typology on the HIV risk behavior outcomes. These findings suggest that both Americanism and Hispanicism play an important role in the etiology of HIV risk behaviors among Hispanic youth and that both, along with family functioning, are important to consider when designing preventive interventions for this population.

    Knowledge of the genome-wide rate and spectrum of mutations is necessary to understand the origin of disease and the genetic variation driving all evolutionary processes. Here, we provide a genome-wide analysis of the rate and spectrum of mutations obtained in two Daphnia pulex genotypes via separate mutation-accumulation (MA) experiments. Unlike most MA studies that utilize haploid, homozygous, or self-fertilizing lines, D. pulex can be propagated ameiotically while maintaining a naturally heterozygous, diploid genome, allowing the capture of the full spectrum of genomic changes that arise in a heterozygous state. While base-substitution mutation rates are similar to those in other multicellular eukaryotes (about 4 × 10(-9) per site per generation), we find that the rates of large-scale (>100 kb) de novo copy-number variants (CNVs) are significantly elevated relative to those seen in previous MA studies. The heterozygosity maintained in this experiment allowed for estimates of gene-conversion processes. While most of the conversion tract lengths we report are similar to those generated by meiotic processes, we also find larger tract lengths that are indicative of mitotic processes. Comparison of MA lines to natural isolates reveals that a majority of large-scale CNVs in natural populations are removed by purifying selection. The mutations observed here share similarities with disease-causing, complex, large-scale CNVs, thereby demonstrating that MA studies in D. pulex serve as a system for studying the processes leading to such alterations.

    Dissolved CO2 during geological CO2 storage may react with minerals in fractured rocks, confined aquifers, or faults, resulting in mineral precipitation and dissolution. The overall rate of reaction can be affected by coupled processes among hydrodynamics, transport, and reactions at the (sub) pore-scale. In this research pore-scale modeling of coupled fluid flow, reactive transport, and heterogeneous reaction at the mineral surface is applied to account for permeability alterations caused by precipitation-induced pore-blocking. This work is motivated by the observed CO2 seeps from a natural analog to geologic CO2 sequestration at Crystal Geyser, Utah. A key observation is the lateral migration of CO2 seep sites at a scale of ~ 100 meters over time. A pore-scale model provides fundamental mechanistic explanations of how calcite precipitation alters flow paths by pore plugging under different geochemical compositions and pore configurations. In addition, response function of reaction rates will be constructed from pore-scale simulations which account for a range of reaction regimes characterized by the Damkohler and Peclet numbers. Newly developed response functions will be used in a continuum scale model that may account for large-scale phenomena mimicking lateral migration of surface CO2 seeps. Comparison of field observations and simulations results will provide mechanistic explanations of the lateral migration and enhance our understanding of subsurface processes associated with the CO2 injection.

    2002-01-01

    The autoconversion rate is a key process for the formation of precipitation in warm clouds. In climate models, physical processes such as autoconversion rate, which are calculated from grid mean values, are biased, because they do not take subgrid variability into account. Recently, statistical cloud schemes have been introduced in large-scale models to account for partially cloud-covered grid boxes. However, these schemes do not include the in-cloud variability in their parameterizations. In this paper, a new statistically based autoconversion rate considering the in-cloud variability is introduced and tested in three cases using the Canadian Single Column Model (SCM) of the global climate model. The results show that the new autoconversion rate improves the model simulation, especially in terms of liquid water path in all three case studies.

    Background The use of mobile apps for health and well being promotion has grown exponentially in recent years. Yet, there is currently no app-quality assessment tool beyond “star”-ratings. Objective The objective of this study was to develop a reliable, multidimensional measure for trialling, classifying, and rating the quality of mobile health apps. Methods A literature search was conducted to identify articles containing explicit Web or app quality rating criteria published between January 2000 and January 2013. Existing criteria for the assessment of app quality were categorized by an expert panel to develop the new Mobile App Rating Scale (MARS) subscales, items, descriptors, and anchors. There were sixty well being apps that were randomly selected using an iTunes search for MARS rating. There were ten that were used to pilot the rating procedure, and the remaining 50 provided data on interrater reliability. Results There were 372 explicit criteria for assessing Web or app quality that were extracted from 25 published papers, conference proceedings, and Internet resources. There were five broad categories of criteria that were identified including four objective quality scales: engagement, functionality, aesthetics, and information quality; and one subjective quality scale; which were refined into the 23-item MARS. The MARS demonstrated excellent internal consistency (alpha = .90) and interrater reliability intraclass correlation coefficient (ICC = .79). Conclusions The MARS is a simple, objective, and reliable tool for classifying and assessing the quality of mobile health apps. It can also be used to provide a checklist for the design and development of new high quality health apps. PMID:25760773

    Objectives Acculturation is a multidimensional process involving changes in behaviour and beliefs. Questionnaires developed to measure acculturation are typically designed for specific ethnic populations and adult experiences. This study developed a questionnaire that measures acculturation among ethnically diverse populations of youth that can be included as a module in population surveys. Methods Questionnaires measuring acculturation in youth were identified in the literature. The importance of items from the existing questionnaires was determined using a Delphi process and this informed the development of our questionnaire. The questionnaire was then pilot tested using a sample of 248 Canadians aged 18–25 via an online system. Participants identified as East and South East Asian (27.8%), South Asian (17.7%) and Black (13.7%). The majority were 1st (33.5%) or 2nd generation immigrants (52.0%). After redundant items were eliminated, exploratory factor analysis grouped items into domains, and, for each domain, internal consistency, and convergent validity with immigrant generation then age at immigration estimated. A subset of participants re-completed the questionnaire for reliability estimation. Results The literature review yielded 117 articles that used 13 questionnaires with a total of 440 questions. The Delphi process reduced these to 32 questions. Pilot testing occurred in 248 Canadians aged 18–25. Following item reduction, 16 questions in three domains remained: dominant culture, heritage language, and heritage culture. All had good internal consistency (Cronbach’s alphas > .75). The mean dominant domain score increased with immigrant generation (1st generation: 3.69 (95% CI: 3.49–3.89), 2nd: 4.13 (4.00–4.26), 3rd: 4.40 (4.19–4.61)), and mean heritage language score was higher among those who immigrated after age 12 than before (p = .0001), indicative of convergent validity. Conclusions This Bicultural Youth Acculturation Questionnaire has

    Theoretical considerations suggest that the mammalian metabolic rate is linearly proportional to the surface areas of mitochondria, capillary, and alveolar membranes. However, the scaling exponents of these surface areas to the mammals' body mass (approximately 0.9-1) are higher than exponents of the resting metabolic rate (RMR) to body mass (approximately 0.75), although similar to the one of exercise metabolic rate (EMR); the underlying physiological cause of this mismatch remains unclear. The analysis presented here shows that discrepancies between the scaling exponents of RMR and the relevant surface areas may originate from, at least for the system of alveolar membranes in mammalian lungs, the facts that (i) not all of the surface area is involved in the gas exchange and (ii) that larger mammals host a smaller effective surface area that participates in the material exchange rate. A result of these facts is that lung surface areas unused at rest are activated under heavy breathing conditions (e.g., exercise), wherein larger mammals support larger activated surface areas that provide a higher capability to increase the gas-exchange rate, allowing for mammals to meet, for example, the high energetic demands of foraging and predation.

  12. French version validation of the psychotic symptom rating scales (PSYRATS) for outpatients with persistent psychotic symptoms

    2012-01-01

    Background Most scales that assess the presence and severity of psychotic symptoms often measure a broad range of experiences and behaviours, something that restricts the detailed measurement of specific symptoms such as delusions or hallucinations. The Psychotic Symptom Rating Scales (PSYRATS) is a clinical assessment tool that focuses on the detailed measurement of these core symptoms. The goal of this study was to examine the psychometric properties of the French version of the PSYRATS. Methods A sample of 103 outpatients suffering from schizophrenia or schizoaffective disorders and presenting persistent psychotic symptoms over the previous three months was assessed using the PSYRATS. Seventy-five sample participants were also assessed with the Positive And Negative Syndrome Scale (PANSS). Results ICCs were superior to .90 for all items of the PSYRATS. Factor analysis replicated the factorial structure of the original version of the delusions scale. Similar to previous replications, the factor structure of the hallucinations scale was partially replicated. Convergent validity indicated that some specific PSYRATS items do not correlate with the PANSS delusions or hallucinations. The distress items of the PSYRATS are negatively correlated with the grandiosity scale of the PANSS. Conclusions The results of this study are limited by the relatively small sample size as well as the selection of participants with persistent symptoms. The French version of the PSYRATS partially replicates previously published results. Differences in factor structure of the hallucinations scale might be explained by greater variability of its elements. The future development of the scale should take into account the presence of grandiosity in order to better capture details of the psychotic experience. PMID:23020603

  13. Genetic Analysis of Genome-Scale Recombination Rate Evolution in House Mice

    The rate of meiotic recombination varies markedly between species and among individuals. Classical genetic experiments demonstrated a heritable component to population variation in recombination rate, and specific sequence variants that contribute to recombination rate differences between individuals have recently been identified. Despite these advances, the genetic basis of species divergence in recombination rate remains unexplored. Using a cytological assay that allows direct in situ imaging of recombination events in spermatocytes, we report a large (∼30%) difference in global recombination rate between males of two closely related house mouse subspecies (Mus musculus musculus and M. m. castaneus). To characterize the genetic basis of this recombination rate divergence, we generated an F2 panel of inter-subspecific hybrid males (n = 276) from an intercross between wild-derived inbred strains CAST/EiJ (M. m. castaneus) and PWD/PhJ (M. m. musculus). We uncover considerable heritable variation for recombination rate among males from this mapping population. Much of the F2 variance for recombination rate and a substantial portion of the difference in recombination rate between the parental strains is explained by eight moderate- to large-effect quantitative trait loci, including two transgressive loci on the X chromosome. In contrast to the rapid evolution observed in males, female CAST/EiJ and PWD/PhJ animals show minimal divergence in recombination rate (∼5%). The existence of loci on the X chromosome suggests a genetic mechanism to explain this male-biased evolution. Our results provide an initial map of the genetic changes underlying subspecies differences in genome-scale recombination rate and underscore the power of the house mouse system for understanding the evolution of this trait.

    Removing aromatic carbon from an aqueous slurry of cesium-137 and other alkali tetraphenylborates by acid hydrolysis will be an important step in preparing high-level radioactive waste for vitrification at the Savannah River Site`s Defense Waste Processing Facility (DWPF). Kinetic data obtained in bench-scale precipitate hydrolysis reactors suggest changes in operating parameters to improve product quality in the future plant-scale radioactive operation. The rate-determining step is the removal of the fourth phenyl group, i.e. hydrolysis of phenylboronic acid. Efforts to maximize this rate have established the importance of several factors in the system, including the ratio of copper(II) catalyst to formic acid, the presence of nitrite ion, reactions of diphenylmercury, and the purge gas employed in the system.

    A 4-species animal model suitable for experimental study of the effect of change in gravitational loading on the scale relationship between metabolic rate and total body mass is used to study the effect of temperature on metabolic rate in six male animals, 8-10 months of age, of each of the four species in the ambient temperature range 20-36 C. The measurements taken permitted partitioning of total body heat output into sensible heat loss by radiation, conduction and convection, and into latent heat loss by evaporation of water from the body surface. It is shown that the condition of thermoneutrality is important for metabolic scale effect studies, and that the thermoneutral zone for the species considered here is a narrow one.

    We address the understudied religious dimension of acculturation in acculturating adolescents who combine a religious Islamic heritage with a secularized Christian mainstream culture. The religiosity of 197 Turkish Belgian adolescents was compared with that of 366 agemates in Turkey (the heritage culture) and 203 in Belgium (the mainstream culture) and related to cultural values, acculturation orientations, and ethnic identification. Belgian adolescents showed lower and declining religiosity with age, whereas Turkish and Turkish Belgian adolescents were more religious regardless of age. Acculturating adolescents reaffirmed religion as compared with monocultural adolescents in Turkey. Religious reaffirmation was related to cultural values of interdependence, heritage culture maintenance, and ethnic identification. PMID:23155300

    Family relationships can serve as an important source of support during the acculturation process; yet, how the stress related to acculturation, or acculturative stress, may impact family functioning across time is not clear. Participants (n = 479), between the ages of 18-34 were recruited using respondent driven sampling methodology. Findings suggest family cohesion decreased over time; however, it decreased less for those reporting more acculturative stress. The implication is that for those Latino immigrants who struggle to adapt to their new host culture, family remains a source of support more so than for those who do not struggle as much.

    Background: While antipsychotic-induced extrapyramidal symptoms (EPS) and akathisia remain important concerns in the treatment of patients with schizophrenia, the relationship between movement disorder rating scales and spontaneously reported EPS-related adverse events (EPS-AEs) remains unexplored. Methods: Data from four randomized, placebo- and haloperidol-controlled ziprasidone trials were analyzed to examine the relationship between spontaneously reported EPS-AEs with the Simpson Angus Scale (SAS) and Barnes Akathisia Rating Scale (BARS). Categorical summaries were created for each treatment group to show the frequencies of subjects with EPS-AEs in each of the SAS and BARS categories at weeks 1, 3, and 6, and agreement between ratings was quantified by means of weighted kappa (κ). Results: In general, we found greater frequencies of EPS-AEs with increasing severity of the SAS and BARS scores. The EPS-AEs reported with a “none” SAS score ranged from 0 to 22.2%, with a “mild” SAS score from 3.3 to 29.0%, and with a “moderate” SAS score from 0 to 100%. No subjects in any treatment group reported “severe” SAS scores or corresponding EPS-AEs. Agreement between SAS scores and EPS-AEs was poor for ziprasidone and placebo (κ < 0.2) and only slightly better for haloperidol. The EPS-AEs reported with “non questionable” BARS scores ranged from 1.9 to 9.8%, with “mild moderate” BARS scores from 12.8 to 54.6%, and with “marked severe” scores from 0 to 100%. Agreement was modest for ziprasidone and placebo (κ < 0.4) and moderate for haloperidol (κ < 0.6). Conclusions: These findings may reflect either underreporting of AEs by investigators and subjects or erroneous rating scale evaluations. PMID:26116494

    Lean premixed combustion provides a means to reduce pollutant formation and increase combustion efficiency. However, fuel-air mixing is rarely uniform in space and time. This nonuniformity in concentration will lead to relative increases in pollutant formation and decreases in combustion efficiency. The nonuniformity of the concentration at the exit of the premixer has been defined by Lyons (1981) as the ``unmixedness.`` Although turbulence properties such as length scales and strain rate are known to effect unmixedness, the exact relationship is unknown. Evaluating this relationship and the effect of unmixedness in premixed combustion on pollutant formation and combustion efficiency are an important part of the overall goal of US Department of Energy`s Advanced Turbine System (ATS) program and are among the goals of the program described herein. The information obtained from ATS is intended to help to develop and commercialize gas turbines. The contributions to the program which the University of California (Irvine) Combustion Lab (UCICL) will provide are: (1) establish the relationship of inlet unmixedness, length scales, and mean strain rate to performance, (2) determine the optimal levels of inlet unmixedness, length scales, and mean strain rates to maximize combustor performance, and (3) identify efficient premixing methods for achieving the necessary inlet conditions. The program during this reporting period is focused on developing a means to measure and qualify different degrees of temporal and spatial unmixedness. Laser diagnostic methods for planer unmixedness measurements are being developed and preliminary results are presented herein. These results will be used to (1), aid in the design of experimental premixers, and (2), determine the unmixedness which will be correlated with the emissions of the combustor. This measure of unmixedness coupled with length scale, strain rate and intensity information is required to attain the UCI goals.
