Is math anxiety in the secondary classroom limiting physics mastery? A study of math anxiety and physics performance

NASA Astrophysics Data System (ADS)

Mercer, Gary J.

This quantitative study examined the relationship between secondary students with math anxiety and physics performance in an inquiry-based constructivist classroom. The Revised Math Anxiety Rating Scale was used to evaluate math anxiety levels. The results were then compared to the performance on a physics standardized final examination. A simple correlation was performed, followed by a multivariate regression analysis to examine effects based on gender and prior math background. The correlation showed statistical significance between math anxiety and physics performance. The regression analysis showed statistical significance for math anxiety, physics performance, and prior math background, but did not show statistical significance for math anxiety, physics performance, and gender.

Cosmic radiation and solar flares can be a major source of background radiation at the Earth’s surface. This paper examines the relationship between extraterrestrial radiation and the detectable background in radiation portal monitors used for homeland security applications. Background radiation data from 13 radiation portal monitor facilities are examined and compared against external sources of data related to extraterrestrial radiation, including measurements at neutron monitors located at 53 cosmic-ray observatories around the Earth, four polar orbiting satellites, three geostationary satellites, ground-based geomagnetic field data from observatories around the Earth, a solar magnetic index, solar radio flux data, and sunspot activitymore » data. Four-years (January 2003 through December 2006) of data are used in this study, which include the latter part of Solar Cycle 23 as solar activity was on the decline. The analysis shows a significant relationship between some extraterrestrial radiation and the background detected in the radiation portal monitors. A demonstrable decline is shown in the average gamma ray and neutron background at the radiation portal monitors as solar activity declined over the period of the study.« less

A Drastic Change in Background Luminance or Motion Degrades the Preview Benefit.

PubMed

Osugi, Takayuki; Murakami, Ikuya

2017-01-01

When some distractors (old items) precede some others (new items) in an inefficient visual search task, the search is restricted to new items, and yields a phenomenon termed the preview benefit. It has recently been demonstrated that, in this preview search task, the onset of repetitive changes in the background disrupts the preview benefit, whereas a single transient change in the background does not. In the present study, we explored this effect with dynamic background changes occurring in the context of realistic scenes, to examine the robustness and usefulness of visual marking. We examined whether preview benefit in a preview search task survived through task-irrelevant changes in the scene, namely a luminance change and the initiation of coherent motion, both occurring in the background. Luminance change of the background disrupted preview benefit if it was synchronized with the onset of the search display. Furthermore, although the presence of coherent background motion per se did not affect preview benefit, its synchronized initiation with the onset of the search display did disrupt preview benefit if the motion speed was sufficiently high. These results suggest that visual marking can be destroyed by a transient event in the scene if that event is sufficiently drastic.

The Associations Between the Religious Background, Social Supports, and Do-Not-Resuscitate Orders in Taiwan: An Observational Study.

Lin, Kuan-Han; Chen, Yih-Sharng; Chou, Nai-Kuan; Huang, Sheng-Jean; Wu, Chau-Chung; Chen, Yen-Yuan

2016-01-01

Prior studies have demonstrated important implications related to religiosity and a do-not-resuscitate (DNR) decision. However, the association between patients' religious background and DNR decisions is vague. In particular, the association between the religious background of Buddhism/Daoism and DNR decisions has never been examined. The objective of this study was to examine the association between patients' religious background and their DNR decisions, with a particular focus on Buddhism/Daoism.The medical records of the patients who were admitted to the 3 surgical intensive care units (SICU) in a university-affiliated medical center located at Northern Taiwan from June 1, 2011 to December 31, 2013 were retrospectively collected. We compared the clinical/demographic variables of DNR patients with those of non-DNR patients using the Student t test or χ test depending on the scale of the variables. We used multivariate logistic regression analysis to examine the association between the religious backgrounds and DNR decisions.A sample of 1909 patients was collected: 122 patients had a DNR order; and 1787 patients did not have a DNR order. Old age (P = 0.02), unemployment (P = 0.02), admission diagnosis of "nonoperative, cardiac failure/insufficiency" (P = 0.03), and severe acute illness at SICU admission (P < 0.01) were significantly associated with signing of DNR orders. Patients' religious background of Buddhism/Daoism (P = 0.04), married marital status (P = 0.02), and admission diagnosis of "postoperative, major surgery" (P = 0.02) were less likely to have a DNR order written during their SICU stay. Furthermore, patients with poor social support, as indicated by marital and working status, were more likely to consent to a DNR order during SICU stay.This study showed that the religious background of Buddhism/Daoism was significantly associated with a lower likelihood of consenting to a DNR, and poor social support was significantly associated with a higher likelihood of having a DNR order written during SICU stay.

Attractiveness Compensates for Low Status Background in the Prediction of Educational Attainment

PubMed Central

Bauldry, Shawn; Shanahan, Michael J.; Russo, Rosemary; Roberts, Brent W.; Damian, Rodica

2016-01-01

Background People who are perceived as good looking or as having a pleasant personality enjoy many advantages, including higher educational attainment. This study examines (1) whether associations between physical/personality attractiveness and educational attainment vary by parental socioeconomic resources and (2) whether parental socioeconomic resources predict these forms of attractiveness. Based on the theory of resource substitution with structural amplification, we hypothesized that both types of attractiveness would have a stronger association with educational attainment for people from disadvantaged backgrounds (resource substitution), but also that people from disadvantaged backgrounds would be less likely to be perceived as attractive (amplification). Methods This study draws on data from the National Longitudinal Study of Adolescent to Adult Health—including repeated interviewer ratings of respondents’ attractiveness—and trait-state structural equation models to examine the moderation (substitution) and mediation (amplification) of physical and personality attractiveness in the link between parental socioeconomic resources and educational attainment. Results Both perceived personality and physical attractiveness have stronger associations with educational attainment for people from families with lower levels of parental education (substitution). Further, parental education and income are associated with both dimensions of perceived attractiveness, and personality attractiveness is positively associated with educational attainment (amplification). Results do not differ by sex and race/ethnicity. Further, associations between perceived attractiveness and educational attainment remain after accounting for unmeasured family-level confounders using a sibling fixed-effects model. Conclusions Perceived attractiveness, particularly personality attractiveness, is a more important psychosocial resource for educational attainment for people from disadvantaged backgrounds than for people from advantaged backgrounds. People from disadvantaged backgrounds, however, are less likely to be perceived as attractive than people from advantaged backgrounds. PMID:27249216

Little effect of HSP90 inhibition on the quantitative wing traits variation in Drosophila melanogaster.

PubMed

Takahashi, Kazuo H

2017-02-01

Drosophila wings have been a model system to study the effect of HSP90 on quantitative trait variation. The effect of HSP90 inhibition on environmental buffering of wing morphology varies among studies while the genetic buffering effect of it was examined in only one study and was not detected. Variable results so far might show that the genetic background influences the environmental and genetic buffering effect of HSP90. In the previous studies, the number of the genetic backgrounds used is limited. To examine the effect of HSP90 inhibition with a larger number of genetic backgrounds than the previous studies, 20 wild-type strains of Drosophila melanogaster were used in this study. Here I investigated the effect of HSP90 inhibition on the environmental buffering of wing shape and size by assessing within-individual and among-individual variations, and as a result, I found little or very weak effects on environmental and genetic buffering. The current results suggest that the role of HSP90 as a global regulator of environmental and genetic buffering is limited at least in quantitative traits.

Quasi two day wave-related variability in the background dynamics and composition of the mesosphere/thermosphere and the ionosphere

2014-01-01

Dissipating planetary waves in the mesosphere/lower thermosphere (MLT) region may cause changes in the background dynamics of that region, subsequently driving variability throughout the broader thermosphere/ionosphere system via mixing due to the induced circulation changes. We report the results of case studies examining the possibility of such coupling during the northern winter in the context of the quasi two day wave (QTDW)—a planetary wave that recurrently grows to large amplitudes from the summer MLT during the postsolstice period. Six distinct QTDW events between 2003 and 2011 are identified in the MLT using Sounding of the Atmosphere using Broadband Emission Radiometry temperature observations. Concurrent changes to the background zonal winds, zonal mean column O/N2 density ratio, and ionospheric total electron content (TEC) are examined using data sets from Thermosphere Ionosphere Mesosphere Energetics and Dynamics Doppler Interferometer, Global Ultraviolet Imager, and Global Ionospheric Maps, respectively. We find that in the 5–10 days following a QTDW event, the background zonal winds in the MLT show patterns of eastward and westward anomalies in the low and middle latitudes consistent with past modeling studies on QTDW-induced mean wind forcing, both below and at turbopause altitudes. This is accompanied by potentially related decreases in zonal mean thermospheric column O/N2, as well as to low-latitude TECs. The recurrent nature of the above changes during the six QTDW events examined point to an avenue for vertical coupling via background dynamics and chemistry of the thermosphere/ionosphere not previously observed. Key Points Dissipating planetary waves (PWs) in the MLT can drive background wind changes Mixing from dissipating PWs drive thermosphere/ionosphere composition changes First observations of QTDW-driven variability from this mechanism PMID:26312201

2013-08-01

The aim of our study was to identify subgroups of patients attending the Scottish Diabetic Retinopathy Screening (DRS) programme who might safely move from annual to two yearly retinopathy screening. This was a retrospective cohort study of screening data from the DRS programme collected between 2005 and 2011 for people aged ≥12 years with type 1 or type 2 diabetes in Scotland. We used hidden Markov models to calculate the probabilities of transitions to referable diabetic retinopathy (referable background or proliferative retinopathy) or referable maculopathy. The study included 155,114 individuals with no referable diabetic retinopathy or maculopathy at their first DRS examination and with one or more further DRS examinations. There were 11,275 incident cases of referable diabetic eye disease (9,204 referable maculopathy, 2,071 referable background or proliferative retinopathy). The observed transitions to referable background or proliferative retinopathy were lower for people with no visible retinopathy vs mild background retinopathy at their prior examination (respectively, 1.2% vs 8.1% for type 1 diabetes and 0.6% vs 5.1% for type 2 diabetes). The lowest probability for transitioning to referable background or proliferative retinopathy was among people with two consecutive screens showing no visible retinopathy, where the probability was <0.3% for type 1 and <0.2% for type 2 diabetes at 2 years. Transition rates to referable diabetic eye disease were lowest among people with type 2 diabetes and two consecutive screens showing no visible retinopathy. If such people had been offered two yearly screening the DRS service would have needed to screen 40% fewer people in 2009.

The cluster lens can be used as a natural telescope to study the faint end of the (log N)-(log S) relation for the sources which account for the X-ray background.

Effects of background color and symbol arrangement cues on construction of multi-symbol messages by young children without disabilities: implications for aided AAC design.

PubMed

Thistle, Jennifer J; Wilkinson, Krista

2017-09-01

Children whose speech does not meet their communication needs often benefit from augmentative and alternative communication (AAC). The design of an AAC display may influence the child's ability to communicate effectively. The current study examined how symbol background color cues and symbol arrangement affected construction of multi-symbol messages using line-drawing symbols, by young children with typical development. Participants (N = 52) heard a spoken phrase matching a photograph and selected line drawings within a 4 × 4 array. Friedman two-way ANOVAs evaluated speed and accuracy of multi-symbol message construction under four conditions in which the background color and arrangement of symbols was manipulated. Participants demonstrated significantly faster response times when symbols were arranged by word-class category compared to no symbol arrangement. The majority of children responded faster when symbols had white backgrounds, but this effect failed to reach statistical significance. This study provides preliminary evidence suggesting the importance of symbol arrangement for young children. The findings highlight the need for caution when incorporating background color on displays for young children. Future research is needed to examine the effect of visual cues on children who use AAC and consider additional factors that could influence efficacy of symbol arrangement and background color use.

[Effects of exposure frequency and background information on preferences for photographs of cars in different locations].

PubMed

Matsuda, Ken; Kusumi, Takashi; Hosomi, Naohiro; Osa, Atsushi; Miike, Hidetoshi

2014-08-01

This study examined the influence of familiarity and novelty on the mere exposure effect while manipulating the presentation of background information. We selected presentation stimuli that integrated cars and backgrounds based on the results of pilot studies. During the exposure phase, we displayed the stimuli successively for 3 seconds, manipulating the background information (same or different backgrounds with each presentation) and exposure frequency (3, 6, and 9 times). In the judgment phase, 18 participants judged the cars in terms of preference, familiarity, and novelty on a 7-point scale. As the number of stimulus presentations increased, the preference for the cars increased during the different background condition and decreased during the same background condition. This increased preference may be due to the increase in familiarity caused by the higher exposure frequency and novelty resulting from the background changes per exposure session. The rise in preference judgments was not seen when cars and backgrounds were presented independently. Therefore, the addition of novel features to each exposure session facilitated the mere exposure effect.

The Associations Between the Religious Background, Social Supports, and Do-Not-Resuscitate Orders in Taiwan

PubMed Central

Lin, Kuan-Han; Chen, Yih-Sharng; Chou, Nai-Kuan; Huang, Sheng-Jean; Wu, Chau-Chung; Chen, Yen-Yuan

2016-01-01

Abstract Prior studies have demonstrated important implications related to religiosity and a do-not-resuscitate (DNR) decision. However, the association between patients’ religious background and DNR decisions is vague. In particular, the association between the religious background of Buddhism/Daoism and DNR decisions has never been examined. The objective of this study was to examine the association between patients’ religious background and their DNR decisions, with a particular focus on Buddhism/Daoism. The medical records of the patients who were admitted to the 3 surgical intensive care units (SICU) in a university-affiliated medical center located at Northern Taiwan from June 1, 2011 to December 31, 2013 were retrospectively collected. We compared the clinical/demographic variables of DNR patients with those of non-DNR patients using the Student t test or χ2 test depending on the scale of the variables. We used multivariate logistic regression analysis to examine the association between the religious backgrounds and DNR decisions. A sample of 1909 patients was collected: 122 patients had a DNR order; and 1787 patients did not have a DNR order. Old age (P = 0.02), unemployment (P = 0.02), admission diagnosis of “nonoperative, cardiac failure/insufficiency” (P = 0.03), and severe acute illness at SICU admission (P < 0.01) were significantly associated with signing of DNR orders. Patients’ religious background of Buddhism/Daoism (P = 0.04), married marital status (P = 0.02), and admission diagnosis of “postoperative, major surgery” (P = 0.02) were less likely to have a DNR order written during their SICU stay. Furthermore, patients with poor social support, as indicated by marital and working status, were more likely to consent to a DNR order during SICU stay. This study showed that the religious background of Buddhism/Daoism was significantly associated with a lower likelihood of consenting to a DNR, and poor social support was significantly associated with a higher likelihood of having a DNR order written during SICU stay.

Attractiveness Compensates for Low Status Background in the Prediction of Educational Attainment.

PubMed

Bauldry, Shawn; Shanahan, Michael J; Russo, Rosemary; Roberts, Brent W; Damian, Rodica

2016-01-01

People who are perceived as good looking or as having a pleasant personality enjoy many advantages, including higher educational attainment. This study examines (1) whether associations between physical/personality attractiveness and educational attainment vary by parental socioeconomic resources and (2) whether parental socioeconomic resources predict these forms of attractiveness. Based on the theory of resource substitution with structural amplification, we hypothesized that both types of attractiveness would have a stronger association with educational attainment for people from disadvantaged backgrounds (resource substitution), but also that people from disadvantaged backgrounds would be less likely to be perceived as attractive (amplification). This study draws on data from the National Longitudinal Study of Adolescent to Adult Health-including repeated interviewer ratings of respondents' attractiveness-and trait-state structural equation models to examine the moderation (substitution) and mediation (amplification) of physical and personality attractiveness in the link between parental socioeconomic resources and educational attainment. Both perceived personality and physical attractiveness have stronger associations with educational attainment for people from families with lower levels of parental education (substitution). Further, parental education and income are associated with both dimensions of perceived attractiveness, and personality attractiveness is positively associated with educational attainment (amplification). Results do not differ by sex and race/ethnicity. Further, associations between perceived attractiveness and educational attainment remain after accounting for unmeasured family-level confounders using a sibling fixed-effects model. Perceived attractiveness, particularly personality attractiveness, is a more important psychosocial resource for educational attainment for people from disadvantaged backgrounds than for people from advantaged backgrounds. People from disadvantaged backgrounds, however, are less likely to be perceived as attractive than people from advantaged backgrounds.

Evaluations of indoor noise criteria systems based on human response

NASA Astrophysics Data System (ADS)

Bowden, Erica E.; Wang, Lily M.

2005-09-01

The goal of this research is to examine human response to background noise, and relate results to indoor noise criteria. In previous work by the authors, subjects completed perception surveys, typing tasks, and proofreading tasks under typical heating, ventilating, and air-conditioning (HVAC) noise conditions. Results were correlated with commonly used indoor noise criteria systems including noise criteria (NC), room criteria (RC) and others. The findings suggested that the types of tasks used and the length of exposure can impact the results. To examine these two issues, the authors conducted a new study in which each test subject completed 38 total hours of testing over multiple days. Subjects were exposed to several background noise exposures over 20, 40, 80, and 240 minute trials. During the trials, subjects completed a variety of performance tasks and answered questions about their perception of the noise, the thermal environment, and various other factors. Findings from this study were used to determine optimum testing conditions for on-going research examining the effects of tonal or fluctuating background noise on performance, annoyance, and spectral perception. Results are being used to evaluate the effectiveness of commonly used indoor noise criteria systems. [Work supported by INCE and ASHRAE.

Gfeller, Kate; Turner, Christopher; Oleson, Jacob; Kliethermes, Stephanie; Driscoll, Virginia

2012-12-01

This study examined speech recognition abilities of cochlear implant (CI) recipients in the spectrally complex listening condition of 3 contrasting types of background music, and compared performance based upon listener groups: CI recipients using conventional long-electrode devices, Hybrid CI recipients (acoustic plus electric stimulation), and normal-hearing adults. We tested 154 long-electrode CI recipients using varied devices and strategies, 21 Hybrid CI recipients, and 49 normal-hearing adults on closed-set recognition of spondees presented in 3 contrasting forms of background music (piano solo, large symphony orchestra, vocal solo with small combo accompaniment) in an adaptive test. Signal-to-noise ratio thresholds for speech in music were examined in relation to measures of speech recognition in background noise and multitalker babble, pitch perception, and music experience. The signal-to-noise ratio thresholds for speech in music varied as a function of category of background music, group membership (long-electrode, Hybrid, normal-hearing), and age. The thresholds for speech in background music were significantly correlated with measures of pitch perception and thresholds for speech in background noise; auditory status was an important predictor. Evidence suggests that speech reception thresholds in background music change as a function of listener age (with more advanced age being detrimental), structural characteristics of different types of music, and hearing status (residual hearing). These findings have implications for everyday listening conditions such as communicating in social or commercial situations in which there is background music.

Objectives This study (a) examined speech recognition abilities of cochlear implant (CI) recipients in the spectrally complex listening condition of three contrasting types of background music, and (b) compared performance based upon listener groups: CI recipients using conventional long-electrode (LE) devices, Hybrid CI recipients (acoustic plus electric stimulation), and normal-hearing (NH) adults. Methods We tested 154 LE CI recipients using varied devices and strategies, 21 Hybrid CI recipients, and 49 NH adults on closed-set recognition of spondees presented in three contrasting forms of background music (piano solo, large symphony orchestra, vocal solo with small combo accompaniment) in an adaptive test. Outcomes Signal-to-noise thresholds for speech in music (SRTM) were examined in relation to measures of speech recognition in background noise and multi-talker babble, pitch perception, and music experience. Results SRTM thresholds varied as a function of category of background music, group membership (LE, Hybrid, NH), and age. Thresholds for speech in background music were significantly correlated with measures of pitch perception and speech in background noise thresholds; auditory status was an important predictor. Conclusions Evidence suggests that speech reception thresholds in background music change as a function of listener age (with more advanced age being detrimental), structural characteristics of different types of music, and hearing status (residual hearing). These findings have implications for everyday listening conditions such as communicating in social or commercial situations in which there is background music. PMID:23342550

Currie, G P; Sinha, S; Thomson, F; Cleland, J; Denison, A R

2017-06-01

Background Tablet computers have emerged as a tool to capture, process and store data in examinations, yet evidence relating to their acceptability and usefulness in assessment is limited. Methods We performed an observational study to explore opinions and attitudes relating to tablet computer use in recording performance in a final year objective structured clinical examination at a single UK medical school. Examiners completed a short questionnaire encompassing background, forced-choice and open questions. Forced choice questions were analysed using descriptive statistics and open questions by framework analysis. Results Ninety-two (97% response rate) examiners completed the questionnaire of whom 85% had previous use of tablet computers. Ninety per cent felt checklist mark allocation was 'very/quite easy', while approximately half considered recording 'free-type' comments was 'easy/very easy'. Greater overall efficiency of marking and resource savings were considered the main advantages of tablet computers, while concerns relating to technological failure and ability to record free type comments were raised. Discussion In a context where examiners were familiar with tablet computers, they were preferred to paper checklists, although concerns were raised. This study adds to the limited literature underpinning the use of electronic devices as acceptable tools in objective structured clinical examinations.

Is God just a big person? Children's conceptions of God across cultures and religious traditions.

PubMed

Nyhof, Melanie A; Johnson, Carl N

2017-03-01

The present research examines the influence of intuitive cognitive domain and religion on the God concepts of children growing up in religious traditions that present God in ways varying from abstract to concrete. In Study 1, we compared children from a Latter-Day Saints (LDS) background with those from mainstream Christian (MC) backgrounds in the United States. In contrast to MC theology that holds that God is all-knowing, all-powerful, and disembodied, LDS theology depicts God as embodied. In Study 1, 3- to 7-year-olds from LDS and MC backgrounds were asked about supernatural mental and immaterial attributes of God, a ghost, a dad, and a bug. In Study 2, children ages 3-7 from Muslim and Catholic backgrounds in Indonesia were presented with a variant of Study 1. Taken together, the two studies examine the God concepts of children raised in three different religious traditions with God concepts that range from highly abstract to concrete. Overall, we find that the youngest children, regardless of religion, distinguish God from humans and hold similar ideas of God, attributing more supernatural psychological than physical properties. Older children's conceptions of God are more in line with the theological notions of their traditions. The results suggest that children are not simply anthropomorphic in their God concepts, but early on understand supernatural agents as having special mental properties and they continue to learn about differences between agents, influenced by their religious traditions. Statement of contribution What is already known on this subject Research on children's God concepts has established that children begin to distinguish the mind of God from that of humans by around age 4-5. The main debate in the field is whether children start out thinking about God in anthropomorphic terms or whether they start out with an undifferentiated idea of agents' minds as all having access to knowledge. Research on children's understanding of immortality has demonstrated that around the same age that children begin differentiating God's mind from human minds, they also differentiate between the two in terms of life-cycle attributes, attributing immortality to God, but not to humans. What does this study add? The present research contributes to the field by examining the God concepts of children from different religious backgrounds. These religious backgrounds have theologies with God concepts that range from physically concrete (Latter-Day Saints or Mormonism) to highly abstract (Islam). We also include Christian samples for comparison. The present research examines children's attributions to different supernatural agents including God, but also a ghost and an angel. The present studies look at children's attribution of not only supernatural mental attributions, but also the supernatural physical attributions of immateriality and omnipresence that have been understudied. © 2017 The British Psychological Society.

A Chinese young adult non-scientist's epistemologies and her understandings of the concept of speed

NASA Astrophysics Data System (ADS)

Cao, Ying; Brizuela, Barbara M.

2015-08-01

Past research has investigated students' epistemologies while they were taking courses that required an integrated understanding of mathematical and scientific concepts. However, past studies have not investigated students who are not currently enrolled in such classes. Additionally, past studies have primarily focused on individuals who are native English speakers from Western cultures. In this paper, we aim to investigate whether Hammer and his colleagues' claims concerning learners' epistemologies could be extended to individuals who lack advanced mathematics and science training, have had different cultural and learning experiences, and have grown up speaking and learning in another language. To this end, we interviewed a participant with these characteristics about her understandings of the concept of speed. Our findings show that previous theoretical frameworks can be used to explain the epistemologies of the individual examined in this study. The case suggests that these theories may be relevant regardless of the learner's mathematics and science background, language, educational experience, and cultural background. In the future, more cases should be examined with learners from different academic backgrounds and cultures to further support this finding.

Background and aims Tinder is a geo-located online dating application, which is present in almost 200 countries and has 10 million daily users. The aim of the present research was to investigate the motivational, personality, and basic psychological need-related background of problematic Tinder use. Methods After qualitative pretest and item construction, in Study 1 (N = 414), confirmatory factor analysis was conducted to corroborate the different motivational factors behind Tinder use. In Study 2 (N = 346), the associations between Big Five traits, Tinder motivations, and problematic Tinder use were examined with structural equation modeling (SEM). In Study 3 (N = 298), the potential role of general self-esteem, relatedness need satisfaction, and frustration in relation to Tinder-use motivations and problematic Tinder use was examined with SEM. Results In Study 1, a 16-item first-order factor structure was identified with four motivational factors, such as sex, love, self-esteem enhancement, and boredom. In Study 2, problematic Tinder use was mainly related to using Tinder for self-esteem enhancement. The Big Five personality factors were only weakly related to the four motivations and to problematic Tinder use. Counterintuitively, Study 3 showed that instead of global self-esteem, relatedness need frustration was the strongest predictor of self-esteem enhancement Tinder-use motivation which, in turn, was the strongest predictor of problematic Tinder use. Discussion Four motivational factors were identified as predictors of problematic use with need frustration being a relevant background variable instead of general personality traits.

PubMed

Krobisch, Verena; Sonntag, Pia-Theresa; Gül, Kübra; Aronson, Polina; Schenk, Liane

2016-11-01

Background: Migration is associated with an increase of multicultural care settings. The acceptance of such care relations from user’s point of view has been rarely explored yet. Aim: It is examined, if and how elderly migrants from Turkey consider a common migration background respectively a common socio-cultural background of caregivers as relevant. Method: In terms of data triangulation results of a qualitative study and a quantitative study on care expectations of elderly migrants from Turkey have been merged. Data was collected by means of guideline-based and standardised interviews. Analysis included the documentary method according to Bohnsack as well as descriptive and multivariate methods. Results: Cultural and migration-related aspects are considered relevant by the vast majority of respondents. Turkish language skills of caregivers are important to more than three-quarters. According to qualitative results, the possibility to objective as well as culturally shaped intuitive communication in the mother tongue is crucial. Correspondingly, a low level of German language skills and a Turkish ethnic identity are associated with a need of migration-sensitive care. Conclusions: A common socio-cultural background with caregivers and the common mother tongue appear to be prerequisites of good care for elderly migrants from Turkey. Further research should examine the conditions under which multicultural care settings are accepted in this group.

PubMed Central

Beck, James D.; Youngblood, M.; Atkinson, J; Mauriello, S; Kaste, LM; Badner, V; Beaver, S; Becerra, K; Singer, R

2018-01-01

Background The Hispanic/Latino population is projected to increase from 16.7% to 30% by 2050. Previous US national surveys had minimal representation of Hispanic/Latino participants other than Mexican-Americans despite evidence suggesting -Hispanic/Latino country of origin and degree of acculturation influence their health outcomes. This study described prevalence and mean number of cavitated (D3) decayed and filled surfaces, missing teeth and edentulism for Hispanics/Latinos of different national origins. Methods The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) conducted in-person examinations and interviews from over 16,000 participants aged 18–74 in four US cities between March 2008 and June 2011. Missing, filled and carious teeth were identified using modified methods of the National Health and Nutrition Examination Survey. Prevalence estimates (weighted percentages), weighted means, and standard errors were computed for measures. Results Prevalence of decayed surfaces (DS) ranged from 20.2% to 35.5%, depending on Hispanic/Latino background, while the prevalence of decayed and filled surfaces (DFS) ranged from 82.7% to 87.0%, indicating substantial dental treatment. The prevalence of missing teeth (MT) ranged from 49.8% to 63.8% and differed by Hispanic/Latino background. Significant differences in mean number of DS, DFS, and MT according Hispanic/Latino background group existed within each of the age groups and for females and males. Conclusions Oral health status does differ by Hispanic/Latino background even with adjustment for age, sex and other characteristics. Practical Implications These data indicate that Hispanic/Latinos in the US do receive restorative dental treatment and practitioners should consider that Hispanic/Latino origin is associated with oral health status.

The current study examines how the bifactor model of the Youth Psychopathic Traits Inventory (YPI) is related to conduct problems in a sample of Dutch adolescents (N = 2,874; 43% female). It addresses to what extent the YPI dimensions explain variance over and above a General Psychopathy factor (i.e., one factor related to all items) and how the general factor and dimensional factors are related to conduct problems. Group differences in these relations for gender, ethnic background, and age were examined. Results showed that the general factor is most important, but dimensions explain variance over and above the general factor. The general factor, and Affective and Lifestyle dimensions, of the YPI were positively related to conduct problems, whereas the Interpersonal dimension was not, after taking the general factor into account. However, across gender, ethnic background, and age, different dimensions were related to conduct problems over and above the general factor. This suggests that all 3 dimensions should be assessed when examining the psychopathy construct. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

This study aimed to investigate the prevalence, distribution and severity of erosive wear in a group of 16-18-year-olds in the western part of Norway. A second aim was to describe possible associations between caries experience, socioeconomic background and origin of birth. Adolescents (n = 795) attending recall examinations at Public Dental Service (PDS) clinics were also examined for dental erosive wear on index surfaces, using the Visual Erosion Dental Examination scoring system (VEDE). In total, 795 individuals were examined. Dental erosive wear was diagnosed in 59% of the population (44% erosive wear in enamel only, 14% combination of enamel and dentine lesions, 1% erosive wear in dentine only). The palatal surfaces of upper central incisors and occlusal surfaces of first lower molars were affected the most (33% and 48% of all surfaces, respectively). Cuppings on molars were registered in 66% of the individuals with erosive wear. Erosive wear was significantly more prevalent among men (63%) than women (55%) (p = 0.018). There were no significant associations between dental erosive wear and caries experience, socioeconomic background or origin of birth.

Effect of Background Pressure on the Performance and Plume of the HiVHAc Hall Thruster

NASA Technical Reports Server (NTRS)

Huang, Wensheng; Kamhawi, Hani; Haag, Thomas

2013-01-01

During the Single String Integration Test of the NASA HiVHAc Hall thruster, a number of plasma diagnostics were implemented to study the effect of varying facility background pressure on thruster operation. These diagnostics include thrust stand, Faraday probe, ExB probe, and retarding potential analyzer. The test results indicated a rise in thrust and discharge current with background pressure. There was also a decrease in ion energy per charge, an increase in multiply-charged species production, a decrease in plume divergence, and a decrease in ion beam current with increasing background pressure. A simplified ingestion model was applied to determine the maximum acceptable background pressure for thrust measurement. The maximum acceptable ingestion percentage was found to be around 1%. Examination of the diagnostics results suggest the ionization and acceleration zones of the thruster were shifting upstream with increasing background pressure.

Dental Caries Experience and Utilization of Oral Health Services Among Tibetan Refugee-Background Children in Paonta Sahib, Himachal Pradesh, India.

PubMed

Bhatt, Sumeet; Gaur, Ambika

2018-06-04

The study was done to describe the dental caries experience and dental care utilization among Tibetan refugee-background children in Paonta Sahib, India. The study was conducted on 254 school children in a Tibetan settlement in Paonta Sahib. Examination was done as per World Health Organization Oral Health Assessment criteria (2013). Data on dental services utilization was obtained from the parents of children using a structured questionnaire. Oral examination of 254 school children aged 6-18 years revealed an overall dental caries prevalence of 79.5%. The dental caries experience was greater in the mixed dentition (84%) than secondary dentition (77.3%). The mean DMFT was associated with sex and dental visiting patterns. About 60% children had never visited a dentist before. The main reason for dental visit was tooth removal (43%). The prevalence of dental caries among Tibetan refugee-background school children was high and utilization of dental care was low. A comprehensive oral health program focusing on preventive care and oral health education is recommended.

Examination of Libby, Montana, Fill Material for Background Levels of Amphibole from the Rainy Creek Complex Using Scanning Electron Microscopy and X-Ray Microanalysis

USGS Publications Warehouse

Adams, David T.; Langer, William H.; Hoefen, Todd M.; Van Gosen, Bradley S.; Meeker, Gregory P.

2010-01-01

Natural background levels of Libby-type amphibole in the sediment of the Libby valley in Montana have not, up to this point, been determined. The purpose of this report is to provide the preliminary findings of a study designed by both the U.S. Geological Survey and the U.S. Environmental Protection Agency and performed by the U.S. Geological Survey. The study worked to constrain the natural background levels of fibrous amphiboles potentially derived from the nearby Rainy Creek Complex. The material selected for this study was sampled from three localities, two of which are active open-pit sand and gravel mines. Seventy samples were collected in total and examined using a scanning electron microscope equipped with an energy dispersive x-ray spectrometer. All samples contained varying amounts of feldspars, ilmenite, magnetite, quartz, clay minerals, pyroxene minerals, and non-fibrous amphiboles such as tremolite, actinolite, and magnesiohornblende. Of the 70 samples collected, only three had detectable levels of fibrous amphiboles compatible with those found in the rainy creek complex. The maximum concentration, identified here, of the amphiboles potentially from the Rainy Creek Complex is 0.083 percent by weight.

The impact of different background noises: effects on cognitive performance and perceived disturbance in employees with aided hearing impairment and normal hearing.

PubMed

Hua, Håkan; Emilsson, Magnus; Kähäri, Kim; Widén, Stephen; Möller, Claes; Lyxell, Björn

2014-10-01

Health care professionals frequently meet employees with hearing impairment (HI) who experience difficulties at work. There are indications that the majority of these difficulties might be related to the presence of background noise. Moreover, research has also shown that high-level noise has a more detrimental effect on cognitive performance and self-rated disturbance in individuals with HI than low-level noise. The purpose of this study was to examine the impact of different types of background noise on cognitive performance and perceived disturbance (PD) in employees with aided HI and normal hearing. A mixed factorial design was conducted to examine the effect of noise in four experimental conditions. A total of 40 participants (21 men and 19 women) were recruited to take part in the study. The study sample consisted of employees with HI (n = 20) and normal hearing (n = 20). The group with HI had a mild-moderate sensorineural HI, and they were all frequent hearing-aid users. The current study was conducted by using four general work-related tasks (mental arithmetic, orthographic decoding, phonological decoding, and serial recall) in four different background conditions: (1) quiet, (2) office noise at 56 dBA, (3) daycare noise at 73.5 dBA, and (4) traffic noise at 72.5 dBA. Reaction time and the proportion of correct answers in the working tasks were used as outcome measures of cognitive performance. The Borg CR-10 scale was used to assess PD. Data collection occurred on two separate sessions, completed within 4 wk of each other. All tasks and experimental conditions were used in a counterbalanced order. Two-way analysis of variance with repeated measures was performed to analyze the results. To examine interaction effects, pairwise t-tests were used. Pearson correlation coefficients between reaction time and proportion of correct answers, and cognitive performance and PD were also calculated to examine the possible correlation between the different variables. No significant between-group or within-group differences in cognitive performance were observed across the four background conditions. Ratings of PD showed that both groups rated PD according to noise level, where higher noise level generated a higher PD. The present findings also demonstrated that the group with HI was more disturbed by higher than lower levels of noise (i.e., traffic and daycare setting compared with office setting). This pattern was observed consistently throughout four working tasks where the group with HI reported a significantly greater PD in the daycare and traffic settings compared with office noise. The present results demonstrate that background noise does not impair cognitive performance in nonauditory tasks in employees with HI and normal hearing, but that PD is affected to a greater extent in employees with HI during higher levels of background noise exposure. In addition, this study also supports previous studies regarding the detrimental effects that high-level noise has on employees with HI. Therefore, we emphasize the need of both self-rated and cognitive measurements in hearing care and occupational health services for both employees with normal hearing and HI.

A longitudinal daily diary study of family assistance and academic achievement among adolescents from Mexican, Chinese, and European backgrounds.

PubMed

Telzer, Eva H; Fuligni, Andrew J

2009-04-01

A longitudinal daily diary method was employed to examine the implications of family assistance for the academic achievement of 563 adolescents (53% female) from Mexican (n = 217), Chinese (n = 206), and European (n = 140) backgrounds during the high school years (mean age 14.9 years in 9th grade to 17.8 years in 12th grade). Although changes in family assistance time within individual adolescents were not associated with simultaneous changes in their Grade Point Averages (GPAs), increases in the proportion of days spent helping the family were linked to declines in the GPAs of students from Mexican and Chinese backgrounds. The negative implications of spending more days helping the family among these two groups was not explained by family background factors or changes in study time or school problems. These results suggest that the chronicity rather than the amount of family assistance may be difficult for adolescents from Mexican and Chinese backgrounds.

Females are sensitive to unpleasant human emotions regardless of the emotional context of photographs.

PubMed

Kato, Ryousuke; Takeda, Yuji

2017-06-09

Previous studies have demonstrated that females exhibit higher sensitivity than males to the emotional state of a person in a photograph. The present study examined whether such females' sensitivity to human emotions could be observed even when the background emotional contexts were incongruent with facial expressions. The late positive potential (LPP) was measured while 19-female and 15-male participants viewed a photograph of a face with varied emotional expressions (pleasant, neutral, or unpleasant) superimposed on a background photograph with varied valences (pleasant, neutral, or unpleasant). The results showed that unpleasant background photographs elicited a larger LPP compared to pleasant and neutral background photographs in both female and male participants. In contrast, a larger LPP for the unpleasant face photographs was observed only in female participants. Furthermore, the effect of face photographs did not interact with the effect of background photographs. These results suggest that females are sensitive to human emotions regardless of the emotional context. Copyright © 2017 Elsevier B.V. All rights reserved.

The perception of 3-D shape from shadows cast onto curved surfaces.

PubMed

Norman, J Farley; Lee, Young-lim; Phillips, Flip; Norman, Hideko F; Jennings, L RaShae; McBride, T Ryan

2009-05-01

In a natural environment, cast shadows abound. Objects cast shadows both upon themselves and upon background surfaces. Previous research on the perception of 3-D shape from cast shadows has only examined the informativeness of shadows cast upon flat background surfaces. In outdoor environments, however, background surfaces often possess significant curvature (large rocks, trees, hills, etc.), and this background curvature distorts the shape of cast shadows. The purpose of this study was to determine the extent to which observers can "discount" the distorting effects of curved background surfaces. In our experiments, observers viewed deforming or static shadows of naturally shaped objects, which were cast upon flat and curved background surfaces. The results showed that the discrimination of 3-D object shape from cast shadows was generally invariant over the distortions produced by hemispherical background surfaces. The observers often had difficulty, however, in identifying the shadows cast onto saddle-shaped background surfaces. The variations in curvature which occur in different directions on saddle-shaped background surfaces cause shadow distortions that lead to difficulties in object recognition and discrimination.

Engineering education for the 1980's: A speculation

NASA Technical Reports Server (NTRS)

Covert, E. E.

1975-01-01

The development of a course of study is briefly examined from two points of view. The first represents the background that would seem to be needed for a fledgling engineer upon his entry into the engineering profession and would allow him to complete successfully his on-the-job training, or engineering internship as it were. The second represents that which must be provided on the basis of the students background from secondary school. It is suggested that a course of study viewed in this way is never fixed, but rather evolves continuously. A particular evolving course of study is briefly discussed.

(Biased) Grading of Students' Performance: Students' Names, Performance Level, and Implicit Attitudes.

PubMed

Bonefeld, Meike; Dickhäuser, Oliver

2018-01-01

Biases in pre-service teachers' evaluations of students' performance may arise due to stereotypes (e.g., the assumption that students with a migrant background have lower potential). This study examines the effects of a migrant background, performance level, and implicit attitudes toward individuals with a migrant background on performance assessment (assigned grades and number of errors counted in a dictation). Pre-service teachers ( N = 203) graded the performance of a student who appeared to have a migrant background statistically significantly worse than that of a student without a migrant background. The differences were more pronounced when the performance level was low and when the pre-service teachers held relatively positive implicit attitudes toward individuals with a migrant background. Interestingly, only performance level had an effect on the number of counted errors. Our results support the assumption that pre-service teachers exhibit bias when grading students with a migrant background in a third-grade level dictation assignment.

Poorer detection rates of severe fetal growth restriction in women of likely refugee background: A case for re-focusing pregnancy care.

PubMed

Biro, Mary Anne; East, Christine

2017-04-01

Severe fetal growth restriction (FGR) (< third centile) in a singleton pregnancy undelivered by 40 weeks is one of a number of Victorian Perinatal Services Performance Indicators, which aim to provide a measure of the quality and safety of maternity care. Women of refugee background have been found to have poorer perinatal outcomes compared to others and these outcomes can in part be explained by previous history. However, less access to and engagement with pregnancy care may also be contributing factors. This study examined the impact of likely refugee background on severe FGR in a singleton pregnancy undelivered by 40 weeks. A retrospective study was undertaken utilising data on women who gave birth to a severely growth-restricted infant at Monash Health during January 2013-July 2015. Unadjusted and adjusted analyses were undertaken to examine the association between the mother being of likely refugee background and severe FGR in singletons delivered after 40 weeks. There was an association between the mother being of likely refugee background and giving birth to a severely growth-restricted baby after 40 weeks with these mothers at two and half times the odds compared to mothers of non-refugee background (adjusted odds ratio 2.52; 95% confidence interval: 1.44-4.42). While detecting FGR is clinically challenging, our findings suggest that maternity services need to be supported to offer care tailored to the specific needs of vulnerable and disadvantaged populations. Providing quality, culturally responsive and accessible care is fundamental to addressing refugee maternal and perinatal health inequalities. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Does a Rater's Professional Background Influence Communication Skills Assessment?

PubMed

Artemiou, Elpida; Hecker, Kent G; Adams, Cindy L; Coe, Jason B

2015-01-01

There is increasing pressure in veterinary education to teach and assess communication skills, with the Objective Structured Clinical Examination (OSCE) being the most common assessment method. Previous research reveals that raters are a large source of variance in OSCEs. This study focused on examining the effect of raters' professional background as a source of variance when assessing students' communication skills. Twenty-three raters were categorized according to their professional background: clinical sciences (n=11), basic sciences (n=4), clinical communication (n=5), or hospital administrator/clinical skills technicians (n=3). Raters from each professional background were assigned to the same station and assessed the same students during two four-station OSCEs. Students were in year 2 of their pre-clinical program. Repeated-measures ANOVA results showed that OSCE scores awarded by the rater groups differed significantly: (F(matched_station_1) [2,91]=6.97, p=.002), (F(matched_station_2) [3,90]=13.95, p=.001), (F(matched_station_3) [3,90]=8.76, p=.001), and ((Fmatched_station_4) [2,91]=30.60, p=.001). A significant time effect between the two OSCEs was calculated for matched stations 1, 2, and 4, indicating improved student performances. Raters with a clinical communication skills background assigned scores that were significantly lower compared to the other rater groups. Analysis of written feedback provided by the clinical sciences raters showed that they were influenced by the students' clinical knowledge of the case and that they did not rely solely on the communication checklist items. This study shows that it is important to consider rater background both in recruitment and training programs for communication skills' assessment.

2015-01-01

Background Little research has examined associations of social support with diabetes (or other physical health outcomes) in Hispanics, who are at elevated risk. Purpose We examined associations between social support and diabetes prevalence in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study. Methods Participants were 5181 adults, 18–74 years old, representing diverse Hispanic backgrounds, who underwent baseline exam with fasting blood draw, oral glucose tolerance test, medication review, sociodemographic assessment, and sociocultural exam with functional and structural social support measures. Results In adjusted analyses, one standard deviation higher structural and functional social support related to 16% and 15% lower odds, respectively, of having diabetes. Structural and functional support were related to both previously diagnosed diabetes (OR = .84 and .88, respectively) and newly recognized diabetes prevalence (OR = .84 and .83, respectively). Conclusions Higher functional and structural social support are associated with lower diabetes prevalence in Hispanics/Latinos. PMID:25107504

Postpartum maternal moods and infant size predict performance on a national high school entrance examination.

PubMed

Galler, Janina R; Ramsey, Frank C; Harrison, Robert H; Taylor, John; Cumberbatch, Glenroy; Forde, Victor

2004-09-01

In an earlier series of studies, we documented the effects of feeding practices and postnatal maternal mood on the growth and development of 226 Barbadian children during the first few months of life. In this report, we extend our earlier studies by examining predictive relationships between infant size, feeding practices and postpartum maternal moods and scores on a national high school examination, the Common Entrance Examination (CEE), at 11 to 12 years of age. Feeding practices, anthropometry, and maternal moods, using Zung depression and anxiety scales and a morale scale, were assessed at 7 weeks (n = 158), 3 months (n = 168), and 6 months (n = 209) postpartum. Background variables including sociodemographic and home environmental factors were also assessed during infancy. CEE scores on 169 of the children in the original study were obtained from the Ministry of Education of Barbados. In our sample of 86 boys and 83 girls, we found that reduced infant lengths and weights at 3 and 6 months of age were predictive of lower CEE, especially math scores. Children who were smaller at these early ages had significantly lower scores on the examination than did larger children. Postpartum maternal moods, including reports of despair and anxiety, were also found to be significant predictors of lower CEE scores, especially English scores. However, breast-feeding and other feeding practices were not directly associated with the CEE scores. Background variables, which significantly predicted lower CEE scores, included young maternal age at the time of her first pregnancy, more children in the home, less maternal education, and fewer home conveniences. Significant associations between infant anthropometry, maternal moods and CEE scores were all significant even when these background variables were controlled for. These findings have important implications for developing interventions early in life to improve academic test scores and future opportunities available to children in this setting.

An Examination of Past and Current Influences of Rurality on Lesbians' Overweight/Obesity Risks.

PubMed

Barefoot, K Nikki; Warren, Jacob C; Smalley, K Bryant

2015-06-01

The purpose of our study was to separately examine past (i.e., rural or non-rural background) and present (i.e., current rural or urban location) influences of rurality on the weight status and diet/exercise behaviors of lesbians. A total of 895 lesbians participated in the online study. Participants were surveyed regarding their rurality status, weight/height, and diet/exercise patterns. A 2×2 (location×background) ANCOVA was conducted to explore influences of rurality on body mass index (BMI), while controlling for age, race, and education. Chi-square analyses were used to examine the relationship between dimensions of rurality and diet/exercise behaviors. There was a significant main effect of current location on BMI. No significant interaction between location and background on BMI was found nor was there a significant main effect of background. Lesbians currently living in rural areas were on average obese (M=30.61), with significantly higher BMIs than urban-residing lesbians (M=28.53). The only significant differences that emerged for lesbians' diet/exercise patterns were for current location-more rural-residing lesbians reported they never engage in exercise in comparison to their urban-residing counterparts, with a greater percentage of urban-residing lesbians reporting frequent exercise. Rural lesbians were also more likely to report a diet high in protein. Findings suggest that current rather than past influences of rurality may have a significant impact on lesbians' weight and diet/exercise behaviors and highlight significant obesity-related health disparities for rural-residing lesbians. These findings offer support for the development of culturally-appropriate healthy diet/exercise and weight promotion efforts that are accessible to rural lesbians.

Impacts of Central American Fires on Ozone Air Quality in Texas

NASA Astrophysics Data System (ADS)

Wang, S. C.; Wang, Y.; Lei, R.; Talbot, R. W.

2016-12-01

Background ozone represents the portion of ozone level in one day that cannot be reduced by local emission controls. One of the important factors causing high background ozone events is wildfires. Satellite observations have documented frequent transport of wildfire smoke from Mexico and Central America to the southern US, particularly Texas, causing haze and exceedance of fine particle matters. However, the impact of those fires on background ozone in Texas is poorly understood. In this study, the effects of the Central America fire emissions in spring (Apr-May) from 2000 to 2013 on high background ozone events in Texas are investigated and quantified. We first examine through back trajectory analysis if any high background ozone days in cities of Texas such as Houston can be traced back to fire events in Central America. The GEOS-Chem global chemical transport model and its nested-grid version over North America are used to simulate the periods of the selected cases studies of Central American fires. Long-large transport of gaseous emissions (NOx, VOCs, and CO) from Central American fires are simulated and background ozone concentrations variations in Texas region due to those fire events are also quantified through the difference in model results with and without fire emissions in Central America. Finally, this study connects those fires and high background ozone events, and also quantifies the contribution of fire emissions from Central America on Texas ozone air quality.

Cross-National Estimates of the Effects of Family Background on Student Achievement: A Sensitivity Analysis

NASA Astrophysics Data System (ADS)

Nonoyama-Tarumi, Yuko

2008-01-01

This article uses the data from the Programme for International Student Assessment (PISA) 2000 to examine whether the influence of family background on educational achievement is sensitive to different measures of the family's socio-economic status (SES). The study finds that, when a multidimensional measure of SES is used, the family background has a stronger influence on achievement across countries than if the simpler measure of SES is used. The new measure, which incorporated aspects of parental occupation, education and cultural resources, was not biased towards more wealthy nations, Western nations, or urban population. However, when a proxy of wealth was included in the measure of SES, this reduced the other measured effects of family background on achievement in many countries.

2016-05-01

No regional analyses regarding opioid-dependent patients in maintenance treatment with a migration background have so far been performed in German-speaking countries. This study examined patients with and without a migration background regarding socioeconomic parameters, characteristics of dependency and attitude towards opiate maintenance treatment (OMT). From May to October 2011 patients in OMT from all of the 20 psychiatry clinics and 110 physician practices in Berlin with a licence to provide OMT were included in this analysis. Out of the 986 participating patients, 956 gave information on migration background and of these, 204 (21.3 %) originated from a country other than Germany. Compared to patients without a migration background, their participation in a maintenance program was significantly shorter and they more often expressed a desire to end OMT and wanted a limited duration of OMT. The differences regarding duration of OMT and the wish to end OMT can reflect a stronger desire for abstinence and a different attitude towards maintenance treatment of patients with a migration background.

Effects of aging on neural connectivity underlying selective memory for emotional scenes

PubMed Central

Waring, Jill D.; Addis, Donna Rose; Kensinger, Elizabeth A.

2012-01-01

Older adults show age-related reductions in memory for neutral items within complex visual scenes, but just like young adults, older adults exhibit a memory advantage for emotional items within scenes compared with the background scene information. The present study examined young and older adults’ encoding-stage effective connectivity for selective memory of emotional items versus memory for both the emotional item and its background. In a functional magnetic resonance imaging (fMRI) study, participants viewed scenes containing either positive or negative items within neutral backgrounds. Outside the scanner, participants completed a memory test for items and backgrounds. Irrespective of scene content being emotionally positive or negative, older adults had stronger positive connections among frontal regions and from frontal regions to medial temporal lobe structures than did young adults, especially when items and backgrounds were subsequently remembered. These results suggest there are differences between young and older adults’ connectivity accompanying the encoding of emotional scenes. Older adults may require more frontal connectivity to encode all elements of a scene rather than just encoding the emotional item. PMID:22542836

2015-01-01

Empirical studies examining perceived ethnic discrimination in Latinos of diverse background groups are limited. This study examined prevalence and correlates of discrimination in a diverse sample of U.S. Latinos (N=5,291) from the multi-site Hispanic Community Health Study/Study of Latinos (HCHS/SOL) and HCHS/SOL Sociocultural Ancillary Study. The sample permitted an examination of differences across seven groups (Central American, Cuban, Dominican, Mexican, Puerto Rican, South American, and Other/Multiple Background). Most participants (79.5%) reported lifetime discrimination exposure and prevalence rates ranged from 64.9% to 98% across groups. Structural Equation Models (SEM) indicated that after adjusting for sociodemographic covariates most group differences in reports of discrimination were eliminated. However, Cubans reported the lowest levels of discrimination, overall among all groups. Furthermore, regional effects were more important than group effects. Participants from Chicago reported the highest levels of discrimination in comparison to other regions. Group differences among Latinos appear to be primarily a function of sociodemographic differences in education, income, and acculturation. In addition, differences in exposure to discrimination may be tied to variables associated with both immigration patterns and integration to U.S. culture. Results highlight the importance of considering historical context and the intersection of discrimination and immigration when evaluating the mental health of Latinos. PMID:26491624

2017-01-01

Aim The aim of the present study was to identify the various background variables and its influence on behavior management problems (BMP) in children. Materials and methods The study included 165 children aged 2 to 8 years. During the initial dental visit, an experienced operator obtained each child’s background variables from accompanying guardians using a standardized questionnaire. Children’s dental behavior was rated by Frankel behavior rating scale. The behavior was then analyzed in relation to the answers of the questionnaire, and a logistic regression model was used to determine the power of the variables, separately or combined, to predict BMP. Results The logistic regression analysis considering differences in background variables between children with negative or positive behavior. Four variables turned out to be as predictors: Age, the guardian’s expectation of the child’s behavior at the dental examination, the child’s anxiety when meeting unfamiliar people, and the presence and absence of toothache. Conclusion The present study concluded that by means of simple questionnaire BMP in children may be expected if one of these attributes is found. Clinical significance Information on the origin of dental fear and uncooperative behavior in a child patient prior to treatment process may help the pediatric dentist plan appropriate behavior management and treatment strategy.

Adolescents' expected civic participation: the role of civic knowledge and efficacy beliefs.

PubMed

Manganelli, Sara; Lucidi, Fabio; Alivernini, Fabio

2014-07-01

In the present study we examined the role of civic knowledge and efficacy beliefs as factors that can promote adolescents' expectations to participate in civic activities, while also taking into consideration the influences of socio-economic background and gender differences. Structural equation modelling techniques were used to examine data from the International Civic and Citizenship Study, collected from 3352 eighth grade Italian students. Gender was found to significantly moderate some relationships between the variables, while efficacy beliefs, rather than civic knowledge, positively influenced expected civic participation. Socio-economic background influenced all the variables included in the study, but it had a very small direct influence on adolescents' expected civic participation. It therefore appears that adolescents' expected civic participation can be encouraged by making them more confident about their civic and political abilities. These results extend our understanding of civic engagement in adolescents, and can inform policies aiming to promote it. Copyright © 2014 The Foundation for Professionals in Services for Adolescents.

A comparison of the letter-processing skills of hearing and deaf readers: evidence from five orthographies.

PubMed

Guldenoglu, Birkan; Miller, Paul; Kargin, Tevhide; Hauser, Peter; Rathmann, Christian; Kubus, Okan

2014-04-01

This study was designed to examine the letter-processing skills of prelingually deaf and hearing students recruited from five different orthographic backgrounds (Hebrew, Arabic, English, German, and Turkish). Participants were 128 hearing and 133 deaf 6th-7th graders. They were tested with a same/different paradigm that assessed their ability to process letters under perceptual and conceptual conditions. Findings suggest that the letter-processing skills of deaf readers from some orthographic backgrounds may be underdeveloped in comparison to hearing counterparts. The finding that such letter-processing deficits were restricted to readers of some but not all of the tested orthographies warrants the conclusion that prelingual deafness, per se, does not impede the development of effective letter processing. Evidence for this study is discussed with reference to potential orthography-inherent and educational factors that may explain the existence of letter-processing deficits found in some of the prelingually deaf readers examined in this study.

Influence of magnetic field configuration on magnetohydrodynamic waves in Earth's core

NASA Astrophysics Data System (ADS)

Knezek, Nicholas; Buffett, Bruce

2018-04-01

We develop a numerical model to study magnetohydrodynamic waves in a thin layer of stratified fluid near the surface of Earth's core. Past studies have been limited to using simple background magnetic field configurations. However, the choice of field distribution can dramatically affect the structure and frequency of the waves. To permit a more general treatment of background magnetic field and layer stratification, we combine finite volume and Fourier methods to describe the wave motions. We validate our model by comparisons to previous studies and examine the influence of background magnetic field configuration on two types of magnetohydrodynamic waves. We show that the structure of zonal Magnetic-Archimedes-Coriolis (MAC) waves for a dipole background field is unstable to small perturbations of the field strength in the equatorial region. Modifications to the wave structures are computed for a range of field configurations. In addition, we show that non-zonal MAC waves are trapped near the equator for realistic magnetic field distributions, and that their latitudinal extent depends upon the distribution of magnetic field strength at the CMB.

Objective Malocclusion is a highly prevalent condition, affecting 20–60% of adolescents worldwide. Although its treatment is often expensive and unaffordable for disadvantaged individuals, few studies have examined the relationship between malocclusion and socioeconomic status. We investigated the prevalence of malocclusion among Mongolian adolescents and its association with maternal education in a community-based sample in Mongolia. Design Cross-sectional study. Settings 2 large secondary schools with different backgrounds in Ulaanbaatar, Mongolia. Participants Complete dental casts of 557 randomly recruited Mongolian schoolchildren aged 11–16 years were evaluated using the Dental Health Component of the Index of Orthodontic Treatment Need to dichotomise orthodontic treatment requirements. Exclusion criteria were the presence of orthodontic treatment history and absence of maternal educational status. Questionnaires were administered to caregivers to assess socioeconomic status. Poisson regression analysis was performed to examine the association between malocclusion and maternal educational status. Results The prevalence of malocclusion requiring orthodontic treatment among all adolescents was 35.2% (95% CI 31.2 to 39.2). In the unadjusted analysis, the prevalence ratio (PR) for malocclusion was higher (PR=1.46; 95% CI 0.96 to 2.20) among adolescents of mothers with a high educational background than among those of mothers with a low educational background. After adjusting for covariates, the PR remained significantly higher (PR=1.72; 95% CI 1.06 to 2.82) among adolescents of mothers with a high educational background. Other socioeconomic status variables, including family income and the educational level of the father, showed no association with malocclusion. Conclusions These findings suggest that malocclusion requiring orthodontic treatment in adolescents is more prevalent among children of mothers with high levels of education. Further studies are needed to clarify the behavioural factors and environmental circumstance that contribute to this. PMID:27803108

Transdiagnostic psychiatric symptoms related to visual evoked potential abnormalities.

Bedwell, Jeffrey S; Butler, Pamela D; Chan, Chi C; Trachik, Benjamin J

2015-12-15

Visual processing abnormalities have been reported across a range of psychotic and mood disorders, but are typically examined within a particular disorder. The current study used a novel transdiagnostic approach to examine diagnostic classes, clinician-rated current symptoms, and self-reported personality traits in relation to visual processing abnormalities. We examined transient visual-evoked potentials (VEPs) from 48 adults (56% female), representing a wide range of psychotic and mood disorders, as well as individuals with no history of psychiatric disorder. Stimuli were low contrast check arrays presented on green and red backgrounds. Pairwise comparisons between individuals with schizophrenia-spectrum disorders (SSD), chronic mood disorders (CMD), and nonpsychiatric controls (NC) revealed no overall differences for either P1 or N1 amplitude. However, there was a significant interaction with the color background in which the NC group showed a significant increase in P1 amplitude to the red, vs. green, background, while the SSD group showed no change. This was related to an increase in social anhedonia and general negative symptoms. Stepwise regressions across the entire sample revealed that individuals with greater apathy and/or eccentric behavior had a reduced P1 amplitude. These relationships provide clues for uncovering the underlying causal pathology for these transdiagnostic symptoms. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Reexamining the Relationship between Verbal Knowledge Background and Keyword Training for Vocabulary Acquisition

PubMed

Hogben; Lawson

1997-07-01

The literature on keyword training presents a confusing picture of the usefulness of the keyword method for foreign language vocabulary learning by students with strong verbal knowledge backgrounds. This paper reviews research which notes the existence of conflicting sets of findings concerning the verbal background-keyword training relationship and presents the results of analyses which argue against the assertion made by McDaniel and Pressley (1984) that keyword training will have minimal effect on students with high verbal ability. Findings from regression analyses of data from two studies did not show that the relationship between keyword training and immediate recall performance was moderated by verbal knowledge background. The disparate sets of findings related to the keyword training-verbal knowledge relationship and themes emerging from other research suggest that this relationship requires further examination.

Three forms of assessment of prior knowledge, and improved performance following an enrichment programme, of English second language biology students within the context of a marine theme

NASA Astrophysics Data System (ADS)

Feltham, Nicola F.; Downs, Colleen T.

2002-02-01

The Science Foundation Programme (SFP) was launched in 1991 at the University of Natal, Pietermaritzburg, South Africa in an attempt to equip a selected number of matriculants from historically disadvantaged schools with the skills, resources and self-confidence needed to embark on their tertiary studies. Previous research within the SFP biology component suggests that a major contributor to poor achievement and low retention rates among English second language (ESL) students in the Life Sciences is the inadequate background knowledge in natural history. In this study, SFP student background knowledge was assessed along a continuum of language dependency using a set of three probes. Improved student performance in each of the respective assessments examined the extent to which a sound natural history background facilitated meaningful learning relative to ESL proficiency. Student profiles and attitudes to biology were also examined. Results indicated that students did not perceive language to be a problem in biology. However, analysis of the student performance in the assessment probes indicated that, although the marine course provided the students with the background knowledge that they were initially lacking, they continued to perform better in the drawing and MCQ tools in the post-tests, suggesting that it is their inability to express themselves in the written form that hampers their development. These results have implications for curriculum development within the constructivist framework of the SFP.

Inter- and intraindividual correlations of background abundances of (2)H, (18)O and (17)O in human urine and implications for DLW measurements.

PubMed

Berman, E S F; Melanson, E L; Swibas, T; Snaith, S P; Speakman, J R

2015-10-01

The method of choice for measuring total energy expenditure in free-living individuals is the doubly labeled water (DLW) method. This experiment examined the behavior of natural background isotope abundance fluctuations within and between individuals over time to assess possible methods of accounting for variations in the background isotope abundances to potentially improve the precision of the DLW measurement. In this work, we measured natural background variations in (2)H, (18)O and (17)O in water from urine samples collected from 40 human subjects who resided in the same geographical area. Each subject provided a urine sample for 30 consecutive days. Isotopic abundances in the samples were measured using Off-Axis Integrated Cavity Output Spectroscopy. Autocorrelation analyses demonstrated that the background isotopes in a given individual were not temporally correlated over the time scales of typical DLW studies. Using samples obtained from different individuals on the same calendar day, cross-correlation analyses demonstrated that the background variations of different individuals were not correlated in time. However, the measured ratios of the three isotopes (2)H, (18)O and (17)O were highly correlated (R(2)=0.89-0.96). Although neither specific timing of DLW water studies nor intraindividual comparisons were found to be avenues for reducing the impact of background isotope abundance fluctuations on DLW studies, strong inter-isotope correlations within an individual confirm that use of a dosing ratio of 8‰:1‰ (0.6 p.p.m.: p.p.m.) optimizes DLW precision. Theoretical implications for the possible use of (17)O measurements within a DLW study require further study.

Examination of in vivo tear film stability after eye blink and eye drying

NASA Astrophysics Data System (ADS)

Szczesna, Dorota H.; Kulas, Zbigniew; Kasprzak, Henryk T.; Stenevi, Ulf

2007-07-01

The purpose of this study is to investigate the kinetics of precorneal tear film stabilization process after eye blink and the process of creating the break-up of the tear film layer. The tear film of patients were examined in vivo by used the lateral shearing interferometer. The information about the distribution and stability of the tear film over the cornea is carried by the wave front reflected from the surface of tears and coded in interference fringes. Smooth and regular fringes indicate the smooth surface of tears over the cornea. Immediately after eye blink the interference fringes are observed on background of bright and dark areas. The contrast of this structure fades with time slowly and after 1-3 sec the background of interference fringes becomes uniform. The vertical orientation and instability of this structure suggests connection with eyelid movement and the spread of tears. If the eye is kept open for a long time, bright lines appear in the background of fringes after a dozen seconds. The slowly appearing structure might signify the tear film break-up. In case of eyes after a LASIK surgery the shape of the background structure has different nature and might be stable in time suggesting the stability of the corneal surface irregularities.

Prevalence of periodontitis according to Hispanic or Latino background among study participants of the Hispanic Community Health Study/Study of Latinos.

PubMed

Jiménez, Monik C; Sanders, Anne E; Mauriello, Sally M; Kaste, Linda M; Beck, James D

2014-08-01

Hispanics and Latinos are an ethnically heterogeneous population with distinct oral health risk profiles. Few study investigators have examined potential variation in the burden of periodontitis according to Hispanic or Latino background. The authors used a multicenter longitudinal population-based cohort study to examine the periodontal health status at screening (2008-2011) of 14,006 Hispanic and Latino adults, aged 18 to 74 years, from four U.S. communities who self-identified as Cuban, Dominican, Mexican, Puerto Rican, Central American or South American. The authors present weighted, age-standardized prevalence estimates and corrected standard errors of probing depth (PD), attachment loss (AL) and periodontitis classified according to the case definition established by the Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC-AAP). The authors used a Wald χ(2) test to compare prevalence estimates across Hispanic or Latino background, age and sex. Fifty-one percent of all participants had exhibited total periodontitis (mild, moderate or severe) per the CDC-AAP classification. Cubans and Central Americans exhibited the highest prevalence of moderate periodontitis (39.9 percent and 37.2 percent, respectively). Across all ages, Mexicans had the highest prevalence of PD across severity thresholds. Among those aged 18 through 44 years, Dominicans consistently had the lowest prevalence of AL at all severity thresholds. Measures of periodontitis varied significantly by age, sex and Hispanic or Latino background among the four sampled Hispanic Community Health Study/Study of Latinos communities. Further analyses are needed to account for lifestyle, behavioral, demographic and social factors, including those related to acculturation. Aggregating Hispanics and Latinos or using estimates from Mexicans may lead to substantial underestimation or overestimation of the burden of disease, thus leading to errors in the estimation of needed clinical and public health resources. This information will be useful in informing decisions from public health planning to patient-centered risk assessment.

2012-10-01

Recent research demonstrated that background noise relative to silence impaired subjects' performance in a cognitively driven odor discrimination test. The current study aimed to investigate whether the background noise can also modulate performance in an odor sensitivity task that is less cognitively loaded. Previous studies have shown that the effect of background noise on task performance can be different in relation to degree of extraversion and/or type of noise. Accordingly, we wanted to examine whether the influence of background noise on the odor sensitivity task can be altered as a function of the type of background noise (i.e., nonverbal vs. verbal noise) and the degree of extraversion (i.e., introvert vs. extrovert group). Subjects were asked to conduct an odor sensitivity task in the presence of either nonverbal noise (e.g., party sound) or verbal noise (e.g., audio book), or silence. Overall, the subjects' mean performance in the odor sensitivity task was not significantly different across three auditory conditions. However, with regard to the odor sensitivity task, a significant interaction emerged between the type of background noise and the degree of extraversion. Specifically, verbal noise relative to silence significantly impaired or improved the performance of the odor sensitivity task in the introvert or extrovert group, respectively; the differential effect of introversion/extraversion was not observed in the nonverbal noise-induced task performance. In conclusion, our findings provide new empirical evidence that type of background noise and degree of extraversion play an important role in modulating the effect of background noise on subjects' performance in an odor sensitivity task.

Pathways to child and adolescent psychiatric clinics: a multilevel study of the significance of ethnicity and neighbourhood social characteristics on source of referral

PubMed Central

2011-01-01

Background In the Swedish society, as in many other societies, many children and adolescents with mental health problems do not receive the help they need. As the Swedish society becomes increasingly multicultural, and as ethnic and economic residential segregation become more pronounced, this study utilises ethnicity and neighbourhood context to examine referral pathways to child and adolescent psychiatric (CAP) clinics. Methods The analysis examines four different sources of referrals: family referrals, social/legal agency referrals, school referrals and health/mental health referrals. The referrals of 2054 children aged 11-19 from the Stockholm Child-Psychiatric Database were studied using multilevel logistic regression analyses. Results Results indicate that ethnicity played an important role in how children and adolescents were referred to CAP-clinics. Family referrals were more common among children and adolescents with a Swedish background than among those with an immigrant background. Referrals by social/legal agencies were more common among children and adolescents with African and Asian backgrounds. Children with Asian or South American backgrounds were more likely to have been referred by schools or by the health/mental health care sector. A significant neighbourhood effect was found in relation to family referrals. Children and adolescents from neighbourhoods with low levels of socioeconomic deprivation were more likely to be referred to CAP-clinics by their families in comparison to children from other neighbourhoods. Such differences were not found in relation in relation to the other sources of referral. Conclusions This article reports findings that can be an important first step toward increasing knowledge on reasons behind differential referral rates and uptake of psychiatric care in an ethnically diverse Swedish sample. These findings have implications for the design and evaluation of community mental health outreach programs and should be considered when developing measures and strategies intended to reach and help children with mental health problems. This might involve providing information about the availability and accessibility of health care for children and adolescents with mental health problems to families in certain neighbourhoods and with different ethnic backgrounds.

Association between parenting practices and children's dietary intake, activity behavior and development of body mass index: the KOALA Birth Cohort Study

PubMed Central

2011-01-01

Background Insights into the effects of energy balance-related parenting practices on children's diet and activity behavior at an early age is warranted to determine which practices should be recommended and to whom. The purpose of this study was to examine child and parent background correlates of energy balance-related parenting practices at age 5, as well as the associations of these practices with children's diet, activity behavior, and body mass index (BMI) development. Methods Questionnaire data originated from the KOALA Birth Cohort Study for ages 5 (N = 2026) and 7 (N = 1819). Linear regression analyses were used to examine the association of child and parent background characteristics with parenting practices (i.e., diet- and activity-related restriction, monitoring and stimulation), and to examine the associations between these parenting practices and children's diet (in terms of energy intake, dietary fiber intake, and added sugar intake) and activity behavior (i.e., physical activity and sedentary time) at age 5, as well as BMI development from age 5 to age 7. Moderation analyses were used to examine whether the associations between the parenting practices and child behavior depended on child characteristics. Results Several child and parent background characteristics were associated with the parenting practices. Dietary monitoring, stimulation of healthy intake and stimulation of physical activity were associated with desirable energy balance-related behaviors (i.e., dietary intake and/or activity behavior) and desirable BMI development, whereas restriction of sedentary time showed associations with undesirable behaviors and BMI development. Child eating style and weight status, but not child gender or activity style, moderated the associations between parenting practices and behavior. Dietary restriction and monitoring showed weaker, or even undesirable associations for children with a deviant eating style, whereas these practices showed associations with desirable behavior for normal eaters. By contrast, stimulation to eat healthy worked particularly well for children with a deviant eating style or a high BMI. Conclusion Although most energy balance-related parenting practices were associated with desirable behaviors, some practices showed associations with undesirable child behavior and weight outcomes. Only parental stimulation showed desirable associations with regard to both diet and activity behavior. The interaction between parenting and child characteristics in the association with behavior calls for parenting that is tailored to the individual child. PMID:21401954

A study of the sensitivity of an imaging telescope (GRITS) for high energy gamma-ray astronomy

NASA Technical Reports Server (NTRS)

Yearian, Mason R.

1990-01-01

When a gamma-ray telescope is placed in Earth orbit, it is bombarded by a flux of cosmic protons much greater than the flux of interesting gammas. These protons can interact in the telescope's thermal shielding to produce detectable gamma rays, most of which are vetoed. Since the proton flux is so high, the unvetoed gamma rays constitute a significant background relative to some weak sources. This background increases the observing time required to pinpoint some sources and entirely obscures other sources. Although recent telescopes have been designed to minimize this background, its strength and spectral characteristics were not previously calculated in detail. Monte Carlo calculations are presented which characterize the strength, spectrum and other features of the cosmic proton background using FLUKA, a hadronic cascade program. Several gamma-ray telescopes, including SAS-2, EGRET and the Gamma Ray Imaging Telescope System (GRITS), are analyzed, and their proton-induced backgrounds are characterized. In all cases, the backgrounds are either shown to be low relative to interesting signals or suggestions are made which would reduce the background sufficiently to leave the telescope unimpaired. In addition, several limiting cases are examined for comparison to previous estimates and calibration measurements.

Spectral and temporal changes to speech produced in the presence of energetic and informational maskers.

PubMed

Cooke, Martin; Lu, Youyi

2010-10-01

Talkers change the way they speak in noisy conditions. For energetic maskers, speech production changes are relatively well-understood, but less is known about how informational maskers such as competing speech affect speech production. The current study examines the effect of energetic and informational maskers on speech production by talkers speaking alone or in pairs. Talkers produced speech in quiet and in backgrounds of speech-shaped noise, speech-modulated noise, and competing speech. Relative to quiet, speech output level and fundamental frequency increased and spectral tilt flattened in proportion to the energetic masking capacity of the background. In response to modulated backgrounds, talkers were able to reduce substantially the degree of temporal overlap with the noise, with greater reduction for the competing speech background. Reduction in foreground-background overlap can be expected to lead to a release from both energetic and informational masking for listeners. Passive changes in speech rate, mean pause length or pause distribution cannot explain the overlap reduction, which appears instead to result from a purposeful process of listening while speaking. Talkers appear to monitor the background and exploit upcoming pauses, a strategy which is particularly effective for backgrounds containing intelligible speech.

Agency and facial emotion judgment in context.

PubMed

Ito, Kenichi; Masuda, Takahiko; Li, Liman Man Wai

2013-06-01

Past research showed that East Asians' belief in holism was expressed as their tendencies to include background facial emotions into the evaluation of target faces more than North Americans. However, this pattern can be interpreted as North Americans' tendency to downplay background facial emotions due to their conceptualization of facial emotion as volitional expression of internal states. Examining this alternative explanation, we investigated whether different types of contextual information produce varying degrees of effect on one's face evaluation across cultures. In three studies, European Canadians and East Asians rated the intensity of target facial emotions surrounded with either affectively salient landscape sceneries or background facial emotions. The results showed that, although affectively salient landscapes influenced the judgment of both cultural groups, only European Canadians downplayed the background facial emotions. The role of agency as differently conceptualized across cultures and multilayered systems of cultural meanings are discussed.

The Prevalence and Antecedents of Religious Beliefs About Health Control in the US Population: Variations by Race and Religious Background.

PubMed

Hayward, R David; Krause, Neal; Pargament, Kenneth

2017-12-01

The ways in which religious beliefs influence beliefs about health have important implications for motivation to engage in positive health behaviors and comply with medical treatment. This study examines the prevalence of two health-related religious beliefs: belief in healing miracles and deferral of responsibility for health outcomes to God. Data came from a representative nationwide US survey of religion and health (N = 3010). Full-factorial ANOVA indicated that there were significant differences in both dimensions of belief by race, by religious background, and by the interaction between the two. Black people believed religion played the largest role in health regardless of religious background. Among White and Hispanic groups, Evangelical Protestants placed more responsibility for their health on God in comparison with other religious groups. ANCOVA controlling for background factors socioeconomic status, health, and religious involvement partially explained these group differences.

Persuasiveness of online flu-vaccination promotional banners.

PubMed

Chien, Yu-Hung

2013-04-01

Young people appear to have relatively little motivation to participate in flu-vaccination programs. This study assessed the effectiveness of online banners in efforts to persuade young people to get vaccinated. Specifically, a 2 x 3 between-subjects factorial design was used to examine the effects of message framing (gain vs loss) and color configuration (white text on a red background, black text on a yellow background, and white text on a blue background) on 180 college students' perceptions of the persuasiveness of flu-vaccination promotional banners. Each participant completed a four-item questionnaire, and the results of an analysis of variance showed that persuasiveness scores were higher among participants exposed to a loss-framed than to a gain-framed message, but only when the loss-framed message was presented in white text on a red background. The theoretical and practical implications of manipulating these two factors in the development of effective health-promotion materials are discussed.

Predicted distribution of visible and near-infrared radiant flux above and below a transmittant leaf

NASA Technical Reports Server (NTRS)

Roberts, Dar A.; Adams, John B.; Smith, Milton O.

1990-01-01

The effects are studied analytically of leaf size, leaf height, and background reflectance on the upward and downward radiant flux (RF) of a leaf. The leaf is horizontal and isotropically scattering in the computer model which examines the light environment in three regions about the leaf. The spectral properties of the leaf are based on measurements of the big-leaf maple, and the model is interpreted in terms of relative RF which is defined as a percentage of the total light in the model. The results demonstrate the dependence of upward relative RF on the light's wavelength and background reflectance with large variations in the NIR. Brightness varies directly with distance from background with maximum brightness achieved at lower heights for smaller leaves. These and other results suggest that NIR canopy reflectance due to leaves is highly dependent on the background reflectance.

2018-03-29

People with low income tend to eat less balanced than people with higher income. This seems to be particularly the case for people with migration background. This cross-sectional study examined the relation of consumption patterns of 597 food bank users with different migration background in Germany. Questionnaires were distributed assessing sociodemographic information and consumption patterns. Analyses were conducted using binary logistic regressions. Models were controlled for age, gender, type of household and education. The group of German food bank users consumed fewer fruits and vegetables and less fish compared to all other groups with migration background (former USSR, Balkan region, Middle East). A significant predictor for fruit and vegetable consumption was migration status. Participants from the former USSR consumed less often SSBs compared to the other groups. Dietary recommendations for low income populations should take into consideration other aspects besides income such as migration status.

Bennett, Christopher L; Dudaryk, Roman; Ayers, Andrew L; McNeer, Richard R

2015-12-01

In this study, an operating room simulation environment was adapted to include quadraphonic speakers, which were used to recreate a composed clinical soundscape. To assess validity of the composed soundscape, several acoustic parameters of this simulated environment were acquired in the presence of alarms only, background noise only, or both. These parameters were also measured for comparison from size-matched operating rooms at Jackson Memorial Hospital. The parameters examined included sound level, reverberation time, and predictive metrics of speech intelligibility in quiet and noise. It was found that the sound levels and acoustic parameters were comparable between the simulated environment and the actual operating rooms. The impact of the background noise on the perception of medical alarms was then examined, and was found to have little impact on the audibility of the alarms. This study is a first in kind report of a comparison between the environmental and psychological acoustical parameters of a hospital simulation environment and actual operating rooms.

Quantitative EEG analysis of the maturational changes associated with childhood absence epilepsy

NASA Astrophysics Data System (ADS)

Rosso, O. A.; Hyslop, W.; Gerlach, R.; Smith, R. L. L.; Rostas, J. A. P.; Hunter, M.

2005-10-01

This study aimed to examine the background electroencephalography (EEG) in children with childhood absence epilepsy, a condition whose presentation has strong developmental links. EEG hallmarks of absence seizure activity are widely accepted and there is recognition that the bulk of inter-ictal EEG in this group is normal to the naked eye. This multidisciplinary study aimed to use the normalized total wavelet entropy (NTWS) (Signal Processing 83 (2003) 1275) to examine the background EEG of those patients demonstrating absence seizure activity, and compare it with children without absence epilepsy. This calculation can be used to define the degree of order in a system, with higher levels of entropy indicating a more disordered (chaotic) system. Results were subjected to further statistical analyses of significance. Entropy values were calculated for patients versus controls. For all channels combined, patients with absence epilepsy showed (statistically significant) lower entropy values than controls. The size of the difference in entropy values was not uniform, with certain EEG electrodes consistently showing greater differences than others.

Chemical fractionation and mobility of traffic-related elements in road environments.

PubMed

Adamiec, Ewa

2017-12-01

Due to considerable progress in exhaust control emission technology and extensive regulatory work regarding this issue, non-exhaust sources of air pollution have become a growing concern. This research involved studying three types of road environment samples such as road dust, sludge from storm drains and roadside soil collected from heavily congested and polluted cities in Poland (Krakow, Warszawa, Opole and Wroclaw). Particles below 20 µm were examined since it was previously estimated that this fine fraction of road dust is polluted mostly by metals derived from non-exhaust sources of pollution such as brake linings wear. Chemical analysis of all samples was combined with a fractionation study using BCR protocol. It was concluded that the finest fractions of road environment samples were significantly contaminated with all of the investigated metals, in particular with Zn, Cu, both well-known key tracers of brake and tire wear. In Warszawa, the pollution index for Zn was on average 15-18 times the background value, in Krakow 12 times, in Wroclaw 8-12 times and in Opole 6-9 times the background value. The pollution index for Cu was on average 6-14 times the background in Warszawa, 7-8 times in Krakow, 4-6 times in Wroclaw and in Opole 5 times the background value. Fractionation study revealed that mobility of examined metals decreases in that order: Zn (43-62%) > Cd (25-42%) > Ni (6-16%) > Cu (3-14%) > Pb (1-8%). It should, however, be noted that metals even when not mobile in the environment can become a serious health concern when ingested or inhaled.

Who reports high company performance? A quantitative study of Chinese listed companies in the energy industry.

PubMed

Guo, Daoyan; Chen, Hong; Long, Ruyin

2016-01-01

In the increasingly competitive environment, top managers' background characteristics are undoubtedly vital factors for company performance. This study examines whether the performance of Chinese listed companies in the energy industry differs with respect to top managers' background characteristics and explores the exact distribution interval of top managers' background characteristics when company performance reaches the highest level. The initial sample was collected from the CSMAR database (2005-2014) for listed companies in the energy industry. After removing the outlier and missing data, the final number of observations was determined as 780. Descriptive statistics were used to investigate the present distribution of top managers' background characteristics, factor analysis was used to determine the dimensions of company performance, and one-way ANOVA was used to analyze the differences in company performance and its dimensions with respect to top managers' background characteristics. The findings show that both the age and length of service of top managers present an increasing trend over the years of the study period, whereas the educational level shows no significant changes. The performance of listed companies has three dimensions: profit performance, growth performance, and operating performance. Companies behave differently with regard to their top managers' background characteristics; when the top manager is 40-45 years old, with a doctoral degree and above, and in the 2nd-3rd year of his service period, his company will achieve a higher level of performance. This study contributes to the growing literature on company performance in the Chinese energy industry by demonstrating the differences in the performance of Chinese listed companies in the energy industry with regard to top managers' background characteristics, and reaching conclusions on the optimum distribution interval of top managers' background characteristics when company performance reaches the highest level. This study also provides a valuable reference for organizational reform and performance enhancement, which are urgent problems for the Chinese energy industry.

Examining the career development of Mexican American middle school students: A test of social cognitive career theory

NASA Astrophysics Data System (ADS)

Navarro, Rachel Leah

This study tested portions of Lent, Brown, and Hackett's (1994) Social Cognitive Career Theory (SCCT) in the domain of mathematics and science with a sample of Mexican American middle school students. Results supported a modified path model. This study's findings supported several SCCT propositions regarding the positive relationships among background contextual affordances, learning experiences, self-efficacy, outcome expectations, interests, and goals. However, findings suggested that the influence of person inputs (i.e., gender and generational status) and some background contextual affordances (i.e., acculturation level) on learning experiences may be not be direct; instead, an indirect effect via a relationship with other background contextual affordances (i.e., perceived social support and social class) was found. Furthermore, results supported direct effects of gender on self-efficacy and learning experiences on goal intentions---two relationships not posited in SCCT. Implications for future research and counseling with Mexican American adolescents are discussed.

Work attention in persons with chronic schizophrenia is an important issue in vocational rehabilitation. Some of the research literature indicates that background music may influence visual attention performance. Based on the theory of occupational therapy, environmental sounds, colors and decorations may affect individual performance, this study thus examined the influence of music on work attention in persons with schizophrenia. Participants were recruited from a halfway house in Taipei. Forty-nine (49) patients with chronic schizophrenia volunteered. They had been accepted into vocational rehabilitation and a work-seeking program. The sample included 20 females and 29 males. The participant ages ranged between 29 and 63 years old, and their average age was 47 years old. Using a randomized controlled trial (RCT) study, the participants were assigned to one of three conditions: quiet environment as the control group (n= 16), classical light music as background music (n= 16), and popular music as background music (n= 17). For Group 1 (control group/quiet environment), there was no significant variance (sig = 0.172). For Group 2 (Classical light music), the intervention revealed significant variance (sig = 0.071*). For Group 3 (popular music), the intervention had significant variance (sig = 0.048**). The introduction of background music tended to increase attention test scores of persons with schizophrenia. Moreover, the increase in test attention scores was statistically significant when popular music was played in the background. This result suggested that background music may improve attention performance of persons with chronic schizophrenia. Future research is required with a larger sample size to support the study results.

Consumer on-line behaviors are more important than ever due to highly growth of on-line shopping. The purposes of this study were to design placement methods of background music for shopping website and examine the effect on browsers' emotional and cognitive response. Three placement points of background music during the browsing, i.e. 2 min., 4 min., and 6 min. from the start of browsing were considered for entry points. Both browsing without music (no music) and browsing with constant music volume (full music) were treated as control groups. Participants' emotional state, approach-avoidance behavior intention, and action to adjust music volume were collected. Results showed that participants had a higher level of pleasure, arousal and approach behavior intention for the three placement points than for no music and full music. Most of the participants for full music (5/6) adjusted the background music. Only 16.7% (3/18) participants for other levels turn off the background music. The results indicate that playing background music after the start of browsing is benefit for on-line shopping atmosphere. It is inappropriate to place background music at the start of browsing shopping website. The marketer must manipulated placement methods of background music for a web store carefully.
