Exploring visuospatial abilities and their contribution to constructional abilities and nonverbal intelligence.

PubMed

Trojano, Luigi; Siciliano, Mattia; Cristinzio, Chiara; Grossi, Dario

2018-01-01

The present study aimed at exploring relationships among the visuospatial tasks included in the Battery for Visuospatial Abilities (BVA), and at assessing the relative contribution of different facets of visuospatial processing on tests tapping constructional abilities and nonverbal abstract reasoning. One hundred forty-four healthy subjects with a normal score on Mini Mental State Examination completed the BVA plus Raven's Coloured Progressive Matrices and Constructional Apraxia test. We used Principal Axis Factoring and Parallel Analysis to investigate relationships among the BVA visuospatial tasks, and performed regression analyses to assess the visuospatial contribution to constructional abilities and nonverbal abstract reasoning. Principal Axis Factoring and Parallel Analysis revealed two eigenvalues exceeding 1, accounting for about 60% of the variance. A 2-factor model provided the best fit. Factor 1 included sub-tests exploring "complex" visuospatial skills, whereas Factor 2 included two subtests tapping "simple" visuospatial skills. Regression analyses revealed that both Factor 1 and Factor 2 significantly affected performance on Raven's Coloured Progressive Matrices, whereas only the Factor 1 affected performance on Constructional Apraxia test. Our results supported functional segregation proposed by De Renzi, suggesting clinical caution to utilize a single test to assess visuospatial domain, and qualified the visuospatial contribution in drawing and non-verbal intelligence test.

Yong, L; Chengye, J; Jiong, Q

2006-03-01

To explore the level of, and factors affecting the quality of life (QOL) in childhood epilepsy in China. At the Peking University First Hospital, we consecutively identified 418 parents whose children were with known epilepsy to complete a questionnaire, which included children's demographic characteristics, clinical message of epilepsy, QOL, familial message, parental symptoms of anxiety/depression. Significant (p<0.05) affecting factors of children's quality of life included current educational degree, mental development, age at diagnosis, age at onset, seizure frequency, duration, AED number; parental significant (p<0.05) affecting factors included anxiety, depression and health. On regression analysis, parental anxiety was the most important factor in explaining lower QOL in childhood epilepsy. AEDs, familial economic state, paternal career, seizure frequency were also significant factors. Parental anxiety outweighed the physical factors in determining QOL in childhood epilepsy. Recognition of this will be helpful for professionals to treat disease and improve the QOL of childhood epilepsy.

The role of latitudinal, genetic and temperature variation in the induction of diapause of Papilio glaucus (Lepidoptera: Papilionidae).

PubMed

Ryan, Sean F; Valella, Patti; Thivierge, Gabrielle; Aardema, Matthew L; Scriber, J Mark

2018-04-01

A key adaptation in insects for dealing with variable environmental conditions is the ability to diapause. The tiger swallowtail butterflies, Papilio glaucus and P. canadensis are ideal species to explore the genetic causes and population genetic consequences of diapause because divergence in this trait is believed to be a salient factor in maintaining a hybrid zone between these species. Yet little is known about the factors that influence diapause induction in this system. Here we explored how spatial (latitudinal), environmental (temperature) and genetic (hybridization) factors affect diapause induction in this system. Specifically, a series of growth chamber experiments using wild caught individuals from across the eastern United States were performed to: (1) evaluate how critical photoperiod varies with latitude, (2) isolate the stage in which induction occurs, (3) test whether changes in temperature affected rates of diapause induction, and (4) explore how the incidence of diapause is affected in hybrid offspring. We find that induction occurs in the larval stage, is not sensitive to a relatively broad range of temperatures, appears to have a complex genetic basis (i.e., is not simply a dominant trait following a Mendelian inheritance pattern) and that the critical photoperiod increases by 0.4 h with each increasing degree in latitude. This work deepens our understanding of how spatial, environmental and genetic variation influences a key seasonal adaptation (diapause induction) in a well-developed ecological model system and will make possible future studies that explore how climatic variation affects the population dynamics and genetics of this system. © 2016 Institute of Zoology, Chinese Academy of Sciences.

Exenberger, Silvia; Ramalingam, Panch; Höfer, Stefan

2016-10-13

Few studies explore posttraumatic growth (PTG) in children from Eastern cultures. To help address this gap, the present study examined PTG among 177 South Indian children aged 8-17 years who were affected by the 2004 Tsunami. The study identifies the underlying factor structure of the Tamil version of the Revised Posttraumatic Growth Inventory for Children (PTGI-C-R), and aims to explore the prevalence of PTG, the relationship between distress and growth, and gender and age differences in PTG. The results of the principal component analysis indicated a two-factor structure with an interpersonal and a person-centred dimension of growth. The total scores of the Tamil PTGI-C-R were positively associated with posttraumatic stress symptoms (PTSS) and age. Moreover, there was a significant relationship between age and the person-centred growth subscale. Non-parametric tests found no gender differences in perceived growth. The role of socio-cultural factors on the nature of PTG is discussed. © 2016 International Union of Psychological Science.

Jairak, Rath; Sahakhunchai, Napath; Jairak, Kallaya; Praneetpolgrang, Prasong

This research aims to explore the factors that affect the intention to use in Social Networking Sites (SNS). We apply the theory of Technology Acceptance Model (TAM), intrinsic motivation, and trust properties to develop the theoretical framework for SNS users' intention. The results show that the important factors influencing SNS users' intention for general purpose and collaborative learning are task-oriented, pleasure-oriented, and familiarity-based trust. In marketing usage, dispositional trust and pleasure-oriented are two main factors that reflect intention to use in SNS.

What influences the impact of pressure ulcers on health-related quality of life? A qualitative patient-focused exploration of contributory factors.

Gorecki, C; Nixon, J; Madill, A; Firth, J; Brown, J M

2012-02-01

With the recognition of health-related quality of life (HRQL) as an important and relevant outcome in pressure ulceration, it is important to gain better understanding of the complex relationship among the various factors that affect it. A problem with existing literature in this area is that the impact of having a pressure ulcer on HRQL is combined conceptually with contributory factors which may influence outcome. This study identified contributory factors affecting pressure ulcer-related HRQL and explored interrelationships between factors based on views of adults with pressure ulcers. We obtained patient-reported qualitative data through semi-structured interviews with 30 patients with pressure ulcers recruited from hospital and community settings around England and Northern Ireland. Patients described how pressure ulcers affected their lives by recounting specific relevant events. Events (patient-reported issues) were sorted into categories and data framework analysed to produce a taxonomy of contributory factors. Inter-rater reliability established the extent of agreement between two independent raters. We identified 16 contributory factors, into two theme taxonomy: experience-of-care and individual-patient factors, defined by descriptive components. Our taxonomy is a comprehensive theoretical model of factors that contribute to pressure ulcer-related HRQL. We have also identified further research priorities to inform clinical practice.

A transformative perspective on learning and professional development of Afghan physiotherapists.

PubMed

Wickford, Jenny; Edwards, Ian; Rosberg, Susanne

2012-05-01

The aim of this article is to explore factors that impacted learning of Afghan physiotherapists in a development project to improve the physiotherapy services in a disability programme implemented by a Swedish nongovernmental organisation in Afghanistan. Participant observation, recorded as field notes, was used to document the process, to gain a better understanding of professional development of physiotherapists in Afghanistan. Field notes were analysed and factors affecting learning were interpreted from a perspective inspired by transformative learning. Various factors were identified: a pattern approach to treatment, linear thinking, and socially oriented decision making affected how new things learned were put into practice; concrete representations and an instrumental view of knowledge characterised learning approaches; language barriers, different interpretations of meaning, and cultural codes challenged communication; and a prescriptive, encouraging approach of the expatriate physiotherapy development worker affected teaching and learning. Working with professional development across cultural borders is challenging, and the identified factors impacting learning can help expatriate physiotherapists in adapting training to the Afghan context. Exploring meaning perspectives and communicative learning could enhance understanding of these factors for both expatriate and Afghan physiotherapists and should be a focus in future development activities.

PubMed

Messecar, D C

2000-12-01

This study explored factors that family caregivers described as affecting their ability to use environmental modifications. Intensive interviews and participant observation were used to collect detailed data from 24 primary family caregivers. Several factors that affect the caregivers' ability to implement modification strategies were identified in the analysis. These factors included attributes of the elderly individual, attributes of the modification, quality of the caregiver-elderly relationship, caregivers' skills, personal resources of the caregiver, and the informal and formal supports available. Of these factors, the most important were the salient skills that caregivers need to implement environmental modifications. These findings point to the importance of caregivers receiving skills training in this important dimension of caregiving. Intervention should be based on a collaborative approach that ensures the caregiver and care receiver's needs and preferences are respected.

2010-09-27

Although food prices in major world markets are at or near a historical low, there is increasing concern about food security-the ability of the world to provide healthy and environmentally sustainable diets for all its peoples. This article is an introduction to a collection of reviews whose authors were asked to explore the major drivers affecting the food system between now and 2050. A first set of papers explores the main factors affecting the demand for food (population growth, changes in consumption patterns, the effects on the food system of urbanization and the importance of understanding income distributions) with a second examining trends in future food supply (crops, livestock, fisheries and aquaculture, and 'wild food'). A third set explores exogenous factors affecting the food system (climate change, competition for water, energy and land, and how agriculture depends on and provides ecosystem services), while the final set explores cross-cutting themes (food system economics, food wastage and links with health). Two of the clearest conclusions that emerge from the collected papers are that major advances in sustainable food production and availability can be achieved with the concerted application of current technologies (given sufficient political will), and the importance of investing in research sooner rather than later to enable the food system to cope with both known and unknown challenges in the coming decades.

2018-05-22

Depression is among the major causes of disability with a negative impact on both daily life and work performance. Whilst depression is the primary cause of sick-leave and unemployment in today's workplace there is a lack of knowledge of the needs of individuals with depression regarding their return-to-work (RTW) process. To explore which factors are of critical importance for people suffering from depression and who also are unemployed in their RTW-process and to explore the impact of two vocational approaches on the service users' experiences. The study included participants in two vocational rehabilitation approaches; Individual Enabling and Support (IES) and Traditional Vocational Rehabilitation (TVR). Qualitative methods were applied to explore critical factors in the RTW-process. Individuals with affective disorders including depression and bipolar disorder were included.RESULTSThree themes emerged as critical factors; Experiencing hope and power, Professionals' positive attitudes, beliefs and behaviours, and Employing a holistic perspective and integrating health and vocational service.CONCLUSIONThis study has demonstrated critical factors for the return-to-work process as experienced by persons with depression. To experience hope and power, to meet professionals that believe "you can work", who use a person-centred and holistic service approach, are such factors necessary for gaining a real job. In particular, professionals in TVR need to embrace this understanding since their services were not experienced as including these elements.

CAMPEAU, SERGE; LIBERZON, ISRAEL; MORILAK, DAVID; RESSLER, KERRY

2012-01-01

This review summarizes the major discussion points of a symposium on stress modulation of cognitive and affective processes, which was held during the 2010 workshop on the neurobiology of stress (Boulder, CO, USA). The four discussants addressed a number of specific cognitive and affective factors that are modulated by exposure to acute or repeated stress. Dr David Morilak discussed the effects of various repeated stress situations on cognitive flexibility, as assessed with a rodent model of attentional set-shifting task, and how performance on slightly different aspects of this test is modulated by different prefrontal regions through monoaminergic neurotransmission. Dr Serge Campeau summarized the findings of several studies exploring a number of factors and brain regions that regulate habituation of various autonomic and neuroendocrine responses to repeated audiogenic stress exposures. Dr Kerry Ressler discussed a body of work exploring the modulation and extinction of fear memories in rodents and humans, especially focusing on the role of key neurotransmitter systems including excitatory amino acids and brain-derived neurotrophic factor. Dr Israel Liberzon presented recent results on human decision-making processes in response to exogenous glucocorticoid hormone administration. Overall, these discussions are casting a wider framework on the cognitive/affective processes that are distinctly regulated by the experience of stress and some of the brain regions and neurotransmitter systems associated with these effects.

Tracing a Route and Finding a Shortcut: The Working Memory, Motivational, and Personality Factors Involved.

PubMed

Pazzaglia, Francesca; Meneghetti, Chiara; Ronconi, Lucia

2018-01-01

Wayfinding (WF) is the ability to move around efficiently and find the way from a starting point to a destination. It is a component of spatial navigation, a coordinate and goal-directed movement of one's self through the environment. In the present study, the relationship between WF tasks (route tracing and shortcut finding) and individual factors were explored with the hypothesis that WF tasks would be predicted by different types of cognitive, affective, motivational variables, and personality factors. A group of 116 university students (88 F.) were conducted along a route in a virtual environment and then asked first to trace the same route again, and then to find a shortcut between the start and end points. Several instruments assessing visuospatial working memory, mental rotation ability, self-efficacy, spatial anxiety, positive attitude to exploring, and personality traits were administered. The results showed that a latent spatial ability factor (measured with the visuospatial working memory and mental rotations tests) - controlled for gender - predicted route-tracing performance, while self-report measures of anxiety, efficacy, and pleasure in exploring, and some personality traits were more likely to predict shortcut-finding performance. We concluded that both personality and cognitive abilities affect WF performance, but differently, depending on the requirements of the task.

2010-01-01

Although food prices in major world markets are at or near a historical low, there is increasing concern about food security—the ability of the world to provide healthy and environmentally sustainable diets for all its peoples. This article is an introduction to a collection of reviews whose authors were asked to explore the major drivers affecting the food system between now and 2050. A first set of papers explores the main factors affecting the demand for food (population growth, changes in consumption patterns, the effects on the food system of urbanization and the importance of understanding income distributions) with a second examining trends in future food supply (crops, livestock, fisheries and aquaculture, and ‘wild food’). A third set explores exogenous factors affecting the food system (climate change, competition for water, energy and land, and how agriculture depends on and provides ecosystem services), while the final set explores cross-cutting themes (food system economics, food wastage and links with health). Two of the clearest conclusions that emerge from the collected papers are that major advances in sustainable food production and availability can be achieved with the concerted application of current technologies (given sufficient political will), and the importance of investing in research sooner rather than later to enable the food system to cope with both known and unknown challenges in the coming decades.

2016-01-01

The majority of scientific work addressing relations among affective states and health correlates has focused primarily on their co-occurrence and a limited range of health conditions. We have developed a Special Issue to highlight recent advances in this emerging field of work that addresses the nature and interplay between affective states and disorders, in terms of their impact and consequences from health status and behavior. This Special Issue is organized into three parts classified as (a) co-occurrence and interplay between (b) transdiagnostic factors and (c) sociocultural factors. It is hoped that this issue will (a) alert readers to the significance of this work at different levels of analysis, (b) illustrate the many domains currently being explored via innovative approaches, and (c) identify fecund areas for future systematic study. © The Author(s) 2016.

Human Health and Performance Considerations for Exploration of Near-Earth Asteroids

NASA Technical Reports Server (NTRS)

Kundrot, Craig; Steinberg, Susan; Charles, John

2010-01-01

This presentation will describe the human health and performance issues that are anticipated for the human exploration of near-Earth asteroids (NEA). Humans are considered a system in the design of any such deep-space exploration mission, and exploration of NEA presents unique challenges for the human system. Key factors that define the mission are those that are strongly affected by distance and duration. The most critical of these is deep-space radiation exposure without even the temporary shielding of a nearby large planetary body. The current space radiation permissible exposure limits (PEL) restrict mission duration to 3-10 months depending on age and gender of crewmembers and stage of the solar cycle. Factors that affect mission architecture include medical capability; countermeasures for bone, muscle, and cardiovascular atrophy during continuous weightlessness; restricted food supplies; and limited habitable volume. The design of a habitat that can maintain the physical and psychological health of the crew and support mission operations with limited intervention from Earth will require an integrated research and development effort by NASA s Human Research Program, engineering, and human factors groups. Limited abort and return options for an NEA mission are anticipated to have important effects on crew psychology as well as influence medical supplies and training requirements of the crew. Other important factors are those related to isolation, confinement, communication delays, autonomous operations, task design, small crew size, and even the unchanging view outside the windows for most of the mission. Geological properties of the NEA will influence design of sample handling and containment, and extravehicular activity capabilities including suit ports and tools. A robotic precursor mission that collects basic information on NEA surface properties would reduce uncertainty about these aspects of the mission as well as aid in design of mission architecture and exploration tasks.

Park, Jowon; Song, Yosep; Teng, Ching-I

2011-12-01

The present study explores the links between personality traits and motivations to play online games. We identified the underlying dimensions of motivations to play online games, examined how personality traits predict motivation, and investigated how personality traits predict online gaming behavior (i.e., playing time and preference for game genres). Factor analyses identified five motivational factors: relationships, adventure, escapism, relaxation, and achievement. The regression analyses indicated that two personality traits, extraversion and agreeableness, predicted various motivations; however, personality traits did not affect the playing time and game genre preference.

Perceived barriers to medical-error reporting: an exploratory investigation.

PubMed

Uribe, Claudia L; Schweikhart, Sharon B; Pathak, Dev S; Dow, Merrell; Marsh, Gail B

2002-01-01

Medical-error reporting is an essential component for patient safety enhancement. Unfortunately, medical errors are largely underreported across healthcare institutions. This problem can be attributed to different factors and barriers present at organizational and individual levels that ultimately prevent individuals from generating the report. This study explored the factors that affect medical-error reporting among physicians and nurses at a large academic medical center located in the midwest United States. A nominal group session was conducted to identify the most relevant factors that act as barriers for error reporting. These factors were then used to design a questionnaire that explored the likelihood of the factors to act as barriers and their likelihood to be modified. Using these two parameters, the results were analyzed and combined into a Factor Relevance Matrix. The matrix identifies the factors for which immediate actions should be undertaken to improve medical-error reporting (immediate action factors). It also identifies factors that require long-term strategies (long-term strategy factors) as well as factors that the organization should be aware of but that are of lower priority (awareness factors). The strategies outlined in this study may assist healthcare organizations in improving medical-error reporting, as part of the efforts toward patient-safety enhancement. Although factors affecting medical-error reporting may vary between different organizations, the process used in identifying the factors and the Factor Relevance Matrix developed in this study are easily adaptable to any organizational setting.

Teenagers' perceptions of factors affecting decision-making competence in the management of type 1 diabetes.

PubMed

Viklund, Gunnel; Wikblad, Karin

2009-12-01

Decision-making is an important prerequisite for empowerment. The aim of this study was to explore teenagers' perceptions of factors affecting decision-making competence in diabetes management. A previous study that assessed an empowerment programme for teenagers with diabetes showed no effects on metabolic control or empowerment outcomes, which is not in accordance with results from studies on adult diabetes patients. The definition of empowerment highlights the patient's own responsibility for decision-making. Earlier studies have shown that many teenagers' may not be mature in decision-making competence until late adolescence. To explore the significance of decision-making competence on the effectiveness of empowerment education we wanted to explore teenagers' own view on factors affecting this competence. An explorative, qualitative interview study was conducted with 31 teenagers with type 1 diabetes, aged 12-17 years. The teenagers were interviewed two weeks after completing an empowerment education programme. The interviews were analysed using qualitative content analysis. Five categories stood out as important for decision-making competence: cognitive maturity, personal qualities, experience, social network and parent involvement. Based on the content in the interviews and the five categories, we made an interpretation and formulated an overall theme: 'Teenagers deserve respect and support for their short-comings during the maturity process'. Our conclusion is that teenagers deserve respect for their immature decision-making competence. Decision-making competence was described as cognitive abilities, personal qualifications and experience. To compensate for the deficiencies the teenagers deserve constructive support from their social network and the essential support is expected to come from their parents. These findings can be useful for diabetes team members in supporting teenagers with diabetes and their parents both in individual meetings and when planning and delivering group education.

Factors contributing to work related low back pain among personal care workers in old age.

PubMed

Yeung, Simon S

2012-01-01

This study aims to preliminary explore the work related and individual factors that contributed to the occurrence of low back pain (LBP) that affected work activities of Personal Care Workers (PCWs). A cross-sectional study was conducted to 36 PCWs in an old age home of Hong Kong. The study is divided into three parts: 1) a questionnaire to document the workload exposure factors and the musculoskeletal symptoms survey of the PCWs, 2) work posture evaluation; and 3) an evaluation of the physical fitness and lifting capacity of the PCWs. Univariate analyses were used to explore the risk factors associated with LBP that affected work activities. The results indicated that individual physical profile and lifting capacities did not contribute to occurrence of low back pain at work. For the work demand factors, the perceived physical demands in lifting and lowering heavy objects, awkward sustain neck and back postures, loading on the back, and perceived effort of cleaning task contributed to the occurrence of LBP. For the physical environment factors, thermal stress and improper ventilation were associated with the occurrence of LBP cases. For the individual factor, LBP cases were associated with workers' self perceived muscular effort, and perceived risk of mental illness in response to work requirements.

Sui, J. H.; Yu, Y. F.; Du, Q. F.; Jiang, D. W.

2018-01-01

The construction quality of FRP fishing vessels influences their production, use and industry development. In order to explore the factors that affect the construction quality of FRP fishing vessels, key factors affecting the construction quality of FRP fishing vessels are determined based on the quality problems of FRP fishing vessels constructed. The improved Fishbone Chart is used to analyze the eight factors of “human, machine, material, process, environment, inspection, design and information”. Taking the factors that affect the construction quality of FRP fishing vessels as the central target, the eight influencing factors were condensed into five aspects and a composite Fishbone Chart is drawn. The Fishbone Chart is used as the basic model, the influencing factors are sorted, screened and discriminated, and the system model convenient for construction site management and control is established. Finally, the causes of poor construction of FRP fishing vessels are analyzed and discussed, and relevant suggestions are put forward.

Tobit analysis of vehicle accident rates on interstate highways.

PubMed

Anastasopoulos, Panagiotis Ch; Tarko, Andrew P; Mannering, Fred L

2008-03-01

There has been an abundance of research that has used Poisson models and its variants (negative binomial and zero-inflated models) to improve our understanding of the factors that affect accident frequencies on roadway segments. This study explores the application of an alternate method, tobit regression, by viewing vehicle accident rates directly (instead of frequencies) as a continuous variable that is left-censored at zero. Using data from vehicle accidents on Indiana interstates, the estimation results show that many factors relating to pavement condition, roadway geometrics and traffic characteristics significantly affect vehicle accident rates.

Østefjells, Tiril; Melle, Ingrid; Aminoff, Sofie R; Hellvin, Tone; Hagen, Roger; Lagerberg, Trine Vik; Lystad, June Ullevoldsæter; Røssberg, Jan Ivar

2017-02-01

Metacognitive factors influence depression, but are largely unexplored in bipolar disorders. We examined i) differences in metacognitive beliefs and thought control strategies between individuals with bipolar disorder and controls, and ii) to what extent clinical characteristics were related to levels of metacognitive beliefs and thought control strategies in bipolar disorder. Eighty patients with bipolar disorder were assessed for age at onset of affective disorder, number of affective episodes, symptoms of mania and depression, metacognitive beliefs (MCQ-30) and thought control strategies (TCQ). Control subjects (N=166) completed MCQ-30 and TCQ. Factors impacting on metacognitive beliefs and thought control strategies were explored with multiple linear regressions. Patients with bipolar disorder reported higher levels of unhelpful metacognitive beliefs and thought control strategies than controls. Metacognitive beliefs were mainly influenced by depressive symptoms, and age at onset of affective illness. Thought control strategies were mainly influenced by metacognitive beliefs and age at onset of affective illness. Our findings suggest that metacognitive beliefs and control strategies are relevant in bipolar disorder. Depression and age at onset of affective disorder could contribute to metacognitive beliefs in bipolar disorder, and influence the use of thought control strategies. This indicates potential relationships that warrant further investigation for clinical relevance. Copyright © 2016 Elsevier Inc. All rights reserved.

Phase-factor-dependent symmetries and quantum phases in a three-level cavity QED system.

PubMed

Fan, Jingtao; Yu, Lixian; Chen, Gang; Jia, Suotang

2016-05-03

Unlike conventional two-level particles, three-level particles may support some unitary-invariant phase factors when they interact coherently with a single-mode quantized light field. To gain a better understanding of light-matter interaction, it is thus necessary to explore the phase-factor-dependent physics in such a system. In this report, we consider the collective interaction between degenerate V-type three-level particles and a single-mode quantized light field, whose different components are labeled by different phase factors. We mainly establish an important relation between the phase factors and the symmetry or symmetry-broken physics. Specifically, we find that the phase factors affect dramatically the system symmetry. When these symmetries are breaking separately, rich quantum phases emerge. Finally, we propose a possible scheme to experimentally probe the predicted physics of our model. Our work provides a way to explore phase-factor-induced nontrivial physics by introducing additional particle levels.

2017-06-01

The term "holdover admissions" refers to patients admitted by an overnight physician and whose care is then transferred to a new primary team the next morning. Descriptions of the holdover process in internal medicine are sparse. To identify important factors affecting the quality of holdover handoffs at an internal medicine (IM) residency program and to compare them to previously identified factors for other handoffs. We undertook a qualitative study using structured focus groups and interviews. We analyzed data using qualitative content analysis. IM residents, IM program directors, and hospitalists at a large academic medical center. A nine-question open-ended interview guide. We identified 13 factors describing holdover handoffs. Five factors-physical space, standardization, task accountability, closed-loop verification, and resilience-were similar to those described in prior handoff literature in other specialties. Eight factors were new concepts that may uniquely affect the quality of the holdover handoff in IM. These included electronic health record access, redundancy, unwritten thoughts, different clinician needs, diagnostic uncertainty, anchoring, teaching, and feedback. These factors were organized into five overarching themes: physical environment, information transfer, responsibility, clinical reasoning, and education. The holdover handoff in IM is complex and has unique considerations for achieving high quality. Further exploration of safe, efficient, and educational holdover handoff practices is necessary.

Background Awareness about the process of law making and the factors that affect the legislative process have an important role in improving legislations that are approved by parliaments. Objective This study aimed to explore and analyze the process of development and enactment of law in Iran’s parliament, and factors that might affect the enactment of laws that are related to the allocation and distribution of health sector resources in Iran. Methods In this case study, data were collected through review of literature and national documents, and experts’ interviews. Interviews were performed with selected members of parliament (MPs), ex members of parliament and professionals from the Ministry of Health and Medical Education (MOHME) (15 persons). MAX QDA 10 was used for coding and constructing themes. Data were analyzed in five steps (familiarization, developing a conceptual framework, coding, indexing, and interpretation) using a content analysis with inductive and deductive approaches. Results The main factors that could affect the approval and enactment of legislations related to allocation of healthcare resources in the Iranian parliament were categorized in seven themes including: Importance of issue, resource availability, legislator’s awareness about the topic, lobbying and unofficial relations with influential officials, mentioning strong reasons by MOHME, weakness of previous laws, and positive feedback related to the same laws. Conclusion Although the process of law making in parliament, and implementation of them in health organizations have legal stages, the study showed that several key factors affect this trend. In fact, it is suggested the health policy makers and MPs consider extending a range of factors to improve the process of law making and the efficiency of legislation related to allocation of healthcare resources.

The roles of social factor and internet self-efficacy in nurses' web-based continuing learning.

PubMed

Chiu, Yen-Lin; Tsai, Chin-Chung

2014-03-01

This study was conducted to explore the relationships among social factor, Internet self-efficacy and attitudes toward web-based continuing learning in a clinical nursing setting. The participants recruited were 244 in-service nurses from hospitals in Taiwan. Three instruments were used to assess their perceptions of social factor, Internet self-efficacy (including basic and advanced Internet self-efficacy) and attitudes toward web-based continuing learning (including perceived usefulness, perceived ease of use, affection and behavior). Structural equation modeling (SEM) was utilized to identify the hypothesized structural model. The results of this study support that social factor is a significant factor correlated to Internet self-efficacy and attitudes toward web-based continuing learning (including perceived usefulness, perceived ease of use and affection). In addition, nurses' basic Internet self-efficacy plays a key role in attitudes including perceived usefulness, perceived ease of use and affection. However, advanced self-efficacy was not correlated to any of the attitudes. The behavior dimension was not linked to social factor or Internet self-efficacy, but was linked to perceived ease of use and affection. Copyright © 2013 Elsevier Ltd. All rights reserved.

High-intensity concurrent training positively affects cardiovascular risk factors. Because this was never investigated in multiple sclerosis, the present pilot study explored the impact of this training on cardiovascular risk factors in this population. Before and after 12 weeks of high-intense concurrent training (interval and strength training, 5 sessions per 2 weeks, n = 16) body composition, resting blood pressure and heart rate, 2-h oral glucose tolerance (insulin sensitivity, glycosylated hemoglobin, blood glucose and insulin concentrations), blood lipids (high- and low-density lipoprotein, total cholesterol, triglyceride levels) and C-reactive protein were analyzed. Twelve weeks of high-intense concurrent training significantly improved resting heart rate (-6%), 2-h blood glucose concentrations (-13%) and insulin sensitivity (-24%). Blood pressure, body composition, blood lipids and C-reactive protein did not seem to be affected. Under the conditions of this pilot study, 12 weeks of concurrent high-intense interval and strength training improved resting heart rate, 2-h glucose and insulin sensitivity in multiple sclerosis but did not affect blood C-reactive protein levels, blood pressure, body composition and blood lipid profiles. Further, larger and controlled research investigating the effects of high-intense concurrent training on cardiovascular risk factors in multiple sclerosis is warranted. Implications for rehabilitation High-intensity concurrent training improves cardiovascular fitness. This pilot study explores the impact of this training on cardiovascular risk factors in multiple sclerosis. Despite the lack of a control group, high-intense concurrent training does not seem to improve cardiovascular risk factors in multiple sclerosis.

Effects of current physical activity on affective response to exercise: physical and social-cognitive mechanisms.

PubMed

Magnan, Renee E; Kwan, Bethany M; Bryan, Angela D

2013-01-01

Affective responses during exercise are often important determinants of exercise initiation and maintenance. Current physical activity may be one individual difference that is associated with the degree to which individuals have positive (or negative) affective experiences during exercise. The objective of this study was to explore physical and cognitive explanations of the relationship between current activity status (more versus less active) and affective response during a 30-minute bout of moderate-intensity exercise. Participants reported their current level of physical activity, exercise self-efficacy and affect during a 30-minute bout of moderate-intensity exercise. More active individuals experienced higher levels of positive affect and tranquillity and lower levels of negative affect and fatigue during exercise. Multivariate models for each affective state indicated separate processes through which physical activity may be associated with changes in affect during exercise. These models indicate that affect experienced during physical activity is related to the current activity level and these relationships can be partially explained by the physical and cognitive factors explored in this study. Recommendations for future research to elucidate whether positive affective response to physical activity improves as a function of becoming more active over time are discussed.

Chen, Ching-Fu; Chen, Cheng-Wen

2011-05-01

This paper focuses on a special segment of motorcyclists in Taiwan--riders of heavy motorcycles--and investigates their speeding behavior and its affecting factors. It extends the theory of planned behavior (TPB) to explore motorcyclist speeding behavior by including the variables of psychological flow theory. The levels of sensation-seeking and riding experience are also used as grouping variables to investigate group differences from the influences of their affecting factors on speeding behavior. The results reveal that the psychological flow variables have greater predictive power in explaining speeding behavior than the TPB variables, providing useful insights into the unique nature of this group of motorcyclists, who are more prone to engage in speeding. Group differences with regard to both sensation-seeking and rider experience in speeding behavior are highlighted, and the implications of the findings are discussed. Copyright © 2010 Elsevier Ltd.

Checkland, Kath; Harrison, Stephen; Snow, Stephanie; Coleman, Anna; McDermott, Imelda

2013-01-01

The purpose of this paper is to explore the practical daily work undertaken by middle-level managers in Primary Care Trusts (PCTs), focusing upon the micro-processes by which these managers enact sensemaking in their organisations. The research took a case study approach, undertaking detailed case studies in four PCTs in England. Data collection included shadowing managers, meeting observations and interviews. The research elucidated two categories of enactment behaviour exhibited by PCT managers: presence/absence; and the production of artefacts. Being "present" in or "absent" from meetings enacted sensemaking over and above any concrete contribution to the meeting made by the actors involved. This paper explores the factors affecting these processes, and describes the situations in which enactment of sense is most likely to occur. Producing artefacts such as meeting minutes or PowerPoint slides also enacted sense in the study sites in addition to the content of the artefact. The factors affecting this are explored. The study has practical implications for all managers seeking to maximise their influence in their organisations. It also provides specific evidence relevant to managers working in the new Clinical Commissioning Groups currently being formed in England. The study expands the understanding of sensemaking in organisations in two important ways. Firstly, it moves beyond discourse to explore the ways in which behaviours can enact sense. Secondly, it explores the distinction between active and unconscious sensemaking.

Exploring Tactile Perceptual Dimensions Using Materials Associated with Sensory Vocabulary.

PubMed

Sakamoto, Maki; Watanabe, Junji

2017-01-01

Considering tactile sensation when designing products is important because the decision to purchase often depends on how products feel. Numerous psychophysical studies have attempted to identify important factors that describe tactile perceptions. However, the numbers and types of major tactile dimensions reported in previous studies have varied because of differences in materials used across experiments. To obtain a more complete picture of perceptual space with regard to touch, our study focuses on using vocabulary that expresses tactile sensations as a guiding principle for collecting material samples because these types of words are expected to cover all the basic categories within tactile perceptual space. We collected 120 materials based on a variety of Japanese sound-symbolic words for tactile sensations, and used the materials to examine tactile perceptual dimensions and their associations with affective evaluations. Analysis revealed six major dimensions: "Affective evaluation and Friction," "Compliance," "Surface," "Volume," "Temperature," and "Naturalness." These dimensions include four factors that previous studies have regarded as fundamental, as well as two new factors: "Volume" and "Naturalness." Additionally, we showed that "Affective evaluation" is more closely related to the "Friction" component (slipperiness and dryness) than to other tactile perceptual features. Our study demonstrates that using vocabulary could be an effective method for selecting material samples to explore tactile perceptual space.

2013-01-01

Preeclampsia is a pregnancy-specific disorder that affects 2 to 8% of all pregnancies and remains a leading cause of maternal and perinatal morbidity and mortality worldwide. Diagnosis is based on new onset of hypertension and proteinuria. Multiple organ systems can be affected with severe disease. The wide range of risk factors reflects the heterogeneity of preeclampsia. Obesity, which is increasing at an alarming rate, is also a risk factor for preeclampsia as well as for later life cardiovascular disease. Exploring common features may provide insight into the pathophysiologic mechanisms underlying preeclampsia among obese and overweight women. PMID:24147919

Morelock, John R.

2017-11-01

Studies exploring what it means to be an engineer professionally have been conducted for decades, but have boomed in recent years. This systematic literature review aims to organise extant studies on engineering identity by coding around four key variables: (a) definitions of engineering identity, (b) factors affecting engineering identity development, (c) interventions affecting engineering identity development, and (d) means of measuring identity. In doing so, this review provides strategies for future research and educational interventions to advance work related to engineering identity. Publications were selected for inclusion by screening and appraising results obtained from databases and keywords refined through a scoping study. Derived from key findings, suggestions for future research include bridging disparate strands of engineering identity literature and incorporating more varied methodological approaches. Also from key findings, suggestions for future practice involve better connecting existing definitions of engineering identity and factors known to affect identity development with identity-related interventions.

2015-12-01

The severity of motorway accidents that occurred on the hard shoulder (HS) is higher than for the main carriageway (MC). This paper compares and contrasts the most important factors affecting the severity of HS and MC accidents on motorways in England. Using police reported accident data, the accidents that occurred on motorways in England are grouped into two categories (i.e., HS and MC) according to the location. A generalized ordered logistic regression model is then applied to identify the factors affecting the severity of HS and MC accidents on motorways. The factors examined include accident and vehicle characteristics, traffic and environment conditions, as well as other behavioral factors. Results suggest that the factors positively affecting the severity include: number of vehicles involved in the accident, peak-hour traffic time, and low visibility. Differences between HS and MC accidents are identified, with the most important being the involvement of heavy goods vehicles (HGVs) and driver fatigue, which are found to be more crucial in increasing the severity of HS accidents. Measures to increase awareness of HGV drivers regarding the risk of fatigue when driving on motorways, and especially the nearside lane, should be taken by the stakeholders.

The effects of sexual orientation on state legislators' behavior and priorities.

PubMed

Herrick, Rebekah

2009-01-01

This article explores whether sexual orientation, surrogate representation, and political factors affect legislators' work on gay, lesbian, and bisexual (GLB) interests, and whether the latter explains away the influence of sexual orientation. A survey of openly GLB state legislators and their colleagues was conducted to measure legislators' campaign issues, legislative priorities, surrogate representation, and ambition. This information is supplemented with bill introduction and district data. The results indicate that legislators' sexual orientation strongly influences their work on GLB issues and although surrogate representation and electoral considerations also affect GLB work, they do not explain away the importance of sexual orientation. The implications of this for the relationship between descriptive and substantive representation are explored.

Exploring the dynamics of collective cognition using a computational model of cognitive dissonance

Smart, Paul R.; Sycara, Katia; Richardson, Darren P.

2013-05-01

The socially-distributed nature of cognitive processing in a variety of organizational settings means that there is increasing scientific interest in the factors that affect collective cognition. In military coalitions, for example, there is a need to understand how factors such as communication network topology, trust, cultural differences and the potential for miscommunication affects the ability of distributed teams to generate high quality plans, to formulate effective decisions and to develop shared situation awareness. The current paper presents a computational model and associated simulation capability for performing in silico experimental analyses of collective sensemaking. This model can be used in combination with the results of human experimental studies in order to improve our understanding of the factors that influence collective sensemaking processes.

Individuals who have undergone a lower limb amputation require comprehensive rehabilitation from the multidisciplinary team to ensure optimal treatment outcomes and social integration. Physiotherapists play a pivotal role within the multidisciplinary team and offer patients physical and psychosocial rehabilitative care. Determining patients' satisfaction levels and exploring factors affecting adherence to physiotherapy interventions can inform practice and improve service delivery of rehabilitation within resource poor settings such as South Africa. To determine the level of satisfaction with physiotherapy services rendered to acute and sub-acute in-patients with lower limb amputations and to explore factors affecting adherence to physiotherapy intervention. A prospective survey of 35 patients with lower limb amputations from four public hospitals in South Africa was undertaken. A modified version of the Hampstead rehabilitation centre patient satisfaction questionnaire was utilised. Majority of participants were satisfied with the physiotherapy services whilst a few reported dissatisfaction. Three themes emerged whilst exploring the patients' experience relating to adherence to physiotherapy programmes. Themes included service delivery, patient-therapist interaction and participation barriers and facilitators. Recommendations aimed to improve quality of care and healthcare outcomes thereby enhancing the participants' adherence to the physiotherapy programme.

A qualitative study of contextual factors' impact on measures to reduce surgery cancellations.

Contextual factors influence quality improvement outcomes. Understanding this influence is important when adapting and implementing interventions and translating improvements into new settings. To date, there is limited knowledge about how contextual factors influence quality improvement processes. In this study, we explore how contextual factors affected measures to reduce surgery cancellations, which are a persistent problem in healthcare. We discuss the usefulness of the theoretical framework provided by the model for understanding success in quality (MUSIQ) for this kind of research. We performed a qualitative case study at Førde Hospital, Norway, where we had previously demonstrated a reduction in surgery cancellations. We interviewed 20 clinicians and performed content analysis to explore how contextual factors affected measures to reduce cancellations of planned surgeries. We identified three common themes concerning how contextual factors influenced the change process: 1) identifying a need to change, 2) facilitating system-wide improvement, and 3) leader involvement and support. Input from patients helped identify a need to change and contributed to the consensus that change was necessary. Reducing cancellations required improving the clinical system. This improvement process was based on a strategy that emphasized the involvement of frontline clinicians in detecting and improving system problems. Clinicians shared information about their work by participating in improvement teams to develop a more complete understanding of the clinical system and its interdependencies. This new understanding allowed clinicians to detect system problems and design adequate interventions. Middle managers' participation in the improvement teams and in regular work processes was important for successfully implementing and adapting interventions. Contextual factors interacted with one another and with the interventions to facilitate changes in the clinical system, reducing surgery cancellations. The MUSIQ framework is useful for exploring how contextual factors influence the improvement process and how they influence one another. Discussing data in relation to a theoretical framework can promote greater uniformity in reporting findings, facilitating knowledge-building across studies.

Kowalski-McGraw, Michele; Green-McKenzie, Judith; Pandalai, Sudha P; Schulte, Paul A

2017-11-01

Prescription opioid and benzodiazepine drug use, which has risen significantly, can affect worker health. Exploration of the scientific literature assessed (1) interrelationships of such drug use, occupational risk factors, and illness and injury, and (2) occupational and personal risk factor combinations that can affect their use. The scientific literature from 2000 to 2015 was searched to determine any interrelationships. Evidence for eight conceptual models emerged based on the search yield of 133 articles. These models summarize interrelationships among prescription opioid and benzodiazepine use with occupational injury and illness. Factors associated with the use of these drugs included fatigue, impaired cognition, falls, motor vehicle crashes, and the use of multiple providers. Prescription opioid and benzodiazepine drugs may be both a personal risk factor for work-related injury and a consequence of workplace exposures.

This study explored the effects of contextual, relational and cognitive factors derived from novice nurses' work experiences on emotions and affective commitment to the profession. With an increasing demand for well-trained nurses, it is imperative to investigate which work-related factors most affect their commitment to develop effective strategies to improve work conditions, work satisfaction and emotional attachment. A repeated-measures within subjects design. From September 2013 - September 2014 eighteen novice nurses described work-related experiences in unstructured diaries and scored their emotional state and affective commitment on a scale. The themes that emerged from the 18 diaries (with 580 diary entries) were quantified as contextual, relational and cognitive factors. Contextual factors refer to complexity of care and existential events; relational factors to experiences with patients, support from colleagues, supervisors and physicians; cognitive factors to nurses' perceived competence. The first multilevel regression analysis, based on the 18 diaries with 580 entries, showed that complexity of care, lack of support and lack of competence were negatively related to novice nurses' affective commitment, whereas received support was positively related. The next multilevel regression analyses showed that all contextual, relational and cognitive factors were either related to negative or positive emotions. To retain novice nurses in the profession, it is important to provide support and feedback. This enables novice nurses to deal with the complexity of care and feelings of incompetence and to develop a professional commitment. This article is protected by copyright. All rights reserved.

The role of health communication in vaccination programmes cannot be overemphasized: it has contributed significantly to creating and sustaining demand for vaccination services and improving vaccination coverage. In Nigeria, numerous communication approaches have been deployed but these interventions are not without challenges. We therefore aimed to explore factors affecting the delivery of vaccination communication in Nigeria. We used a qualitative approach and conducted the study in two states: Bauchi and Cross River States in northern and southern Nigeria respectively. We identified factors affecting the implementation of communication interventions through interviews with relevant stakeholders involved in vaccination communication in the health services. We also reviewed relevant documents. Data generated were transcribed verbatim and analysed using thematic analysis. We used the SURE framework to organise the identified factors (barriers and facilitators) affecting vaccination communication delivery. We then grouped these into health systems and community level factors. Some of the commonly reported health system barriers amongst stakeholders interviewed included: funding constraints, human resource factors (health worker shortages, training deficiencies, poor attitude of health workers and vaccination teams), inadequate infrastructure and equipment and weak political will. Community level factors included the attitudes of community stakeholders and of parents and caregivers. We also identified factors that appeared to facilitate communication activities. These included political support, engagement of traditional and religious institutions and the use of organised communication committees. Communication activities are a crucial element of immunization programmes. It is therefore important for policy makers and programme managers to understand the barriers and facilitators affecting the delivery of vaccination communication so as to be able to implement communication interventions more effectively.

Key Impact Factors on Dam Break Fatalities

NASA Astrophysics Data System (ADS)

Huang, D.; Yu, Z.; Song, Y.; Han, D.; Li, Y.

2016-12-01

Dam failures can lead to catastrophes on human society. However, there is a lack of research about dam break fatalities, especially on the key factors that affect fatalities. Based on the analysis of historical dam break cases, most studies have used the regression analysis to explore the correlation between those factors and fatalities, but without implementing optimization to find the dominating factors. In order to understand and reduce the risk of fatalities, this study has proposed a new method to select the impact factors on the fatality. It employs an improved ANN (Artificial Neural Network) combined with LOOCV (Leave-one-out cross-validation) and SFS (Stepwise Forward Selection) approach to explore the nonlinear relationship between impact factors and life losses. It not only considers the factors that have been widely used in the literature but also introduces new factors closely involved with fatalities. Dam break cases occurred in China from 1954 to 2013 are summarized, within which twenty-five cases are selected with a comprehensive coverage of geographic position and temporal variation. Twelve impact factors are taken into account as the inputs, i.e., severity of dam break flood (SF), population at risk (PR), public understanding of dam break (UB), warning time (TW), evacuation condition (EC), weather condition during dam break (WB), dam break mode (MB), water storage (SW), building vulnerability (VB), dam break time (TB), average distance from the affected area to the dam (DD) and preventive measures by government (PG).From those, three key factors of SF, MB and TB are chosen. The proposed method is able to extract the key factors, and the derived fatality model performs well in various types of dam break conditions.

Nurse aide decision making in nursing homes: factors affecting empowerment.

PubMed

Chaudhuri, Tanni; Yeatts, Dale E; Cready, Cynthia M

2013-09-01

To evaluate factors affecting structural empowerment among nurse aides in nursing homes. Structural empowerment can be defined as the actual rather than perceived ability to make autonomous decisions within an organisation. Given the paucity of research on the subject, this study helps to close the gap by identifying factors that affect nurse aide empowerment, that is, decision-making among nurse aides. The data for the study come from self-administered questionnaires distributed to direct-care workers (nurse aides) in 11 nursing homes in a southern state in the USA. Ordinary least square regression models were estimated to analyse the effects of demographic predictors, personal factors (competency, emotional exhaustion and positive attitude) and structural characteristics (coworker and supervisor support, information availability and shared governance) on nurse aide decision-making. Findings suggest race among demographic predictors, emotional exhaustion among personal characteristics, and supervisor support, and shared governance among structural factors, significantly affect nurse aide decision-making. It is important to explore race as one of the central determinants of structural empowerment among nurse aides. In addition, the nature and type of emotional exhaustion that propels decision-making needs to be further examined. The study shows the importance of shared governance and supervisor support for fostering nurse aide empowerment. © 2013 Blackwell Publishing Ltd.

To explore newly graduated nurses' occupational commitment and its associations with their self-assessed professional competence and other work-related factors. As a factor affecting nurse turnover, newly graduated nurses' occupational commitment and its associations with work-related factors needs exploring to retain adequate workforce. Nurses' commitment has mainly been studied as organisational commitment, but newly graduated nurses' occupational commitment and its association with work-related factors needs further studying. This study used descriptive, cross-sectional, correlation design. A convenience sample of 318 newly graduated nurses in Finland participated responding to an electronic questionnaire. Statistical software, NCSS version 9, was used in data analysis. Frequencies, percentages, ranges, means and standard deviations summarised the data. Multivariate Analyses of Variance estimated associations between occupational commitment and work-related variables. IBM SPSS Amos version 22 estimated the model fit of Occupational Commitment Scale and Nurse Competence Scale. Newly graduated nurses' occupational commitment was good, affective commitment reaching the highest mean score. There was a significant difference between the nurse groups in favour of nurses at higher competence levels in all subscales except in limited alternatives occupational commitment. Multivariate analyses revealed significant associations between subscales of commitment and competence, turnover intentions, job satisfaction, earlier professional education and work sector, competence counting only through affective dimension. The association between occupational commitment and low turnover intentions and satisfaction with nursing occupation was strong. Higher general competence indicated higher overall occupational commitment. Managers' recognition of the influence of all dimensions of occupational commitment in newly graduated nurses' professional development is important. Follow-up studies of newly graduated nurses' commitment, its relationship with quality care, managers' role in enhancing commitment and evaluation of the impact of interventions on improving commitment need further studying. © 2015 John Wiley & Sons Ltd.

Pre-hospital time management provides better access to victims of road traffic crashes (RTCs) and can help minimize preventable deaths, injuries and disabilities. While most studies have been focused on measuring various time intervals in the pre-hospital phase, to our best knowledge there is no study exploring the barriers and facilitators that affects these various intervals qualitatively. The present study aimed to explore factors affecting various time intervals relating to road traffic incidents in the pre-hospital phase and provides suggestions for improvements in Iran. The study was conducted during 2013-2014 at both the national and local level in Iran. Overall, 18 face-to-face interviews with emergency medical services (EMS) personnel were used for data collection. Qualitative content analysis was employed to analyze the data. The most important barriers in relation to pre-hospital intervals were related to the manner of cooperation by members of the public with the EMS and their involvement at the crash scene, as well as to pre-hospital system factors, including the number and location of EMS facilities, type and number of ambulances and manpower. These factors usually affect how rapidly the EMS can arrive at the scene of the crash and how quickly victims can be transferred to hospital. These two categories have six main themes: notification interval; activation interval; response interval; on-scene interval; transport interval; and delivery interval. Despite more focus on physical resources, cooperation from members of the public needs to be taken in account in order to achieve better pre-hospital management of the various intervals, possibly through the use of public education campaigns.

To Identify the Important Soil Properties Affecting Dinoseb Adsorption with Statistical Analysis

PubMed Central

Guan, Yiqing; Wei, Jianhui; Zhang, Danrong; Zu, Mingjuan; Zhang, Liru

2013-01-01

Investigating the influences of soil characteristic factors on dinoseb adsorption parameter with different statistical methods would be valuable to explicitly figure out the extent of these influences. The correlation coefficients and the direct, indirect effects of soil characteristic factors on dinoseb adsorption parameter were analyzed through bivariate correlation analysis, and path analysis. With stepwise regression analysis the factors which had little influence on the adsorption parameter were excluded. Results indicate that pH and CEC had moderate relationship and lower direct effect on dinoseb adsorption parameter due to the multicollinearity with other soil factors, and organic carbon and clay contents were found to be the most significant soil factors which affect the dinoseb adsorption process. A regression is thereby set up to explore the relationship between the dinoseb adsorption parameter and the two soil factors: the soil organic carbon and clay contents. A 92% of the variation of dinoseb sorption coefficient could be attributed to the variation of the soil organic carbon and clay contents. PMID:23737715

Exploring ischemia-induced vascular lesions and potential pharmacological intervention strategies.

Aliev, G; Obrenovich, M E; Seyidova, D; de la Torre, J C

2005-01-01

Structural changes in vessels under the influence of ischemia play an important role in the pathogenesis of many diseases, most important of which are stroke and myocardial infarction or myocardial insult. Over the years, information has been gathered, which implicate a role for ischemic vascular changes in the pathogenesis of crush-syndrome, atherosclerosis and other vascular diseases. When blood vessels are damaged they become unresponsive to a stimulus, which normally elicits vasodilatation and can lead to intraluminal thrombosis and ischemic events. The aim of this review is to explore the structural changes seen in vessels affected by ischemia reperfusion injury. With ischemia, the development of observable changes to vascular structure is multifactorial. One key factor is reperfusion ischemic injury. Moreover, the duration of the ischemic event is an important factor when determining both the prognosis and the type of morphological change that is observable in affected vessel walls. In this regard, the deleterious progression of blood flow impairment and its severity depends on the specific organ involved and the type of tissue affected. Further, there are regional differences within affected tissues and the degree of microvascular injury is well correlated with differences in the nature and severity of the ischemic event. Any method aimed at preventing and treating ischemic reperfusion injuries in vessels, based on these investigations, should likewise be able to decrease the early signs of brain, cerebrovascular and heart injury and preserve normal cellular architecture.

Literature pertaining to Voice Recognition abounds with information relevant to the assessment of transitory speech recognition devices. In the past, engineering requirements have dictated the path this technology followed. But, other factors do exist that influence recognition accuracy. This thesis explores the impact of Human Factors on the successful recognition of speech, principally addressing the differences or variability among users. A Threshold Technology T-600 was used for a 100 utterance vocubalary to test 44 subjects. A statistical analysis was conducted on 5 generic categories of Human Factors: Occupational, Operational, Psychological, Physiological and Personal. How the equipment is trained and the experience level of the speaker were found to be key characteristics influencing recognition accuracy. To a lesser extent computer experience, time or week, accent, vital capacity and rate of air flow, speaker cooperativeness and anxiety were found to affect overall error rates.

Effects of abiotic factors on the nanostructure of diatom frustules-ranges and variability.

The intricate patterning of diatom silica frustules at nanometer-to-micrometer scales makes them of interest for a wide range of industrial applications. For some of these applications, a specific size range in nanostructure is required and may be achieved by selecting species with the desired properties. However, as all biological materials, diatom frustules exhibit variability in their morphological parameters and this variability can to some extent be affected and controlled by environmental conditions. In this review, we explore the effects of different environmental factors including salinity, heavy metals, temperature, pH, extracellular Si(OH) 4 or Ge(OH) 4 concentration, light regime, UV irradiance, long-term cultivation, and biotic factors on the nanostructure of diatom frustules. This compilation of studies illustrates that it is possible to affect the nanostructure of diatom frustules in vivo by controlling different environmental factors as well as by direct chemical modification of frustules. We compare these methods and present examples of how these changes affect the range of variability as well as comparing the magnitude of size changes of the most promising methods.

Factors influencing HIV-risk behaviors among HIV-positive urban African Americans.

PubMed

Plowden, Keith O; Fletcher, Audwin; Miller, J Lawrence

2005-01-01

Urban African Americans are disproportionately affected by HIV, the virus associated with AIDS. Although incidence and mortality appear to be decreasing in some populations, they continue to remain steady among inner-city African Americans. A major concern is the number of HIV-positive individuals who continue to practice high-risk behaviors. Understanding factors that increase risks is essential for the development and implementation of effective prevention initiatives. Following a constructionist epistemology, this study used ethnography to explore social and cultural factors that influence high-risk behaviors among inner-city HIV-positive African Americans. Leininger's culture care diversity and universality theory guided the study. Individual qualitative interviews were conducted with HIV-positive African Americans in the community to explore social and cultural factors that increase HIV-risky behaviors. For this study, family/kinship, economic, and education factors played a significant role in risky behaviors. Reducing HIV disparity among African Americans is dependent on designing appropriate interventions that enhance protective factors. Clinicians providing care to HIV-positive individuals can play a key role in reducing transmission by recognizing and incorporating these factors when designing effective prevention interventions.

Exploration data have been used to identify specific sites where this investment has led to a significant contribution in global mineral supply of cobalt or where a significant increase in cobalt production capacity is anticipated in the next 5 years. This report provides an overview of the cobalt industry, factors affecting mineral supply, and circumstances surrounding the development, or lack thereof, of key mineral properties with the potential to affect mineral supply. Of the 48 sites with an effective production capacity of at least 1,000 metric tons per year of cobalt considered for this study, 3 producing sites underwent significant expansion during the study period, 10 exploration sites commenced production from 1995 through 2008, and 16 sites were expected to begin production by 2013 if planned development schedules are met. Cobalt supply is influenced by economic, environmental, political, and technological factors affecting exploration for and production of copper, nickel, and other metals as well as factors affecting the cobalt industry. Cobalt-rich nickel laterite deposits were discovered and developed in Australia and the South Pacific and improvements in laterite processing technology took place during the 1990s and early in the first decade of the 21st century when mining of copper-cobalt deposits in Congo (Kinshasa) was restricted because of regional conflict and lack of investment in that country's mining sector. There was also increased exploration for and greater importance placed on cobalt as a byproduct of nickel mining in Australia and Canada. The emergence of China as a major refined cobalt producer and consumer since 2007 has changed the pattern of demand for cobalt, particularly from Africa and Australasia. Chinese companies are increasingly becoming involved in copper and cobalt exploration and mining in Congo (Kinshasa) and Zambia as well as nickel, copper, and other mining in Australia and the South Pacific. Between 2009 and 2013, mines with a cumulative capacity of more than 100,000 metric tons per year of cobalt were proposed to come into production if all sites came into production as scheduled. This additional capacity corresponds to 175 percent of the 2008 global refinery production level. About 45 percent of this cobalt would be from primary nickel deposits, about 32 percent from primary copper deposits, and about 21 percent from primary cobalt deposits. By 2013, about 40 percent of new capacity was expected to come from the African Copperbelt; 38 percent, from Australia and the South Pacific countries of Philippines, Indonesia, New Caledonia, and Papua New Guinea; 11 percent, from other African countries; 5 percent, from North America; and 6 percent, from other areas.

Liang, Ting-Peng; Yeh, Yi-Hsuan

As value-added services on mobile devices are developing rapidly, text messaging, multi-media messaging, music, video, games, GPS navigation, RFID, and mobile TV are all accessible from a single device. Mobile games that combine mobile communication with computer games are an emerging industry. The purpose of this research is to explore what situation factors may affect the intention to play mobile game. We propose a research model to fit the nature of mobile games and conducted an online survey to examine the effect of situational factors. The model integrates constructs in TAM and TRA. The findings are as follows. First, Subjective norm affects a user’s intention in using mobile games when a user has no other task. Second, perceived playfulness affects a user’s intention to use mobile games when the user has another task.

This study addressed the factors influencing smokers' information seeking pertaining to the health risks of smoking. In particular, this study aimed to extend the risk information seeking and processing model by taking into account the role of autonomous motivations used to stimulate smokers' information-seeking behavior. The results of a Web-based survey indicated that information insufficiency was positively associated with health information-seeking behavior and that negative affective responses were positively associated with information insufficiency and health information-seeking behavior. In addition, autonomous motivations were positively associated with information insufficiency and information-seeking behavior. The results indicated that risk perception was positively related to autonomous motivations and negative affective response. Finally, informational subjective norm was positively related to autonomous motivations and negative affective responses. The implications of this study for future research are discussed.

Pain and trauma in negative pressure wound therapy: a review.

PubMed

Upton, Dominic; Andrews, Abbye

2015-02-01

Negative pressure wound therapy (NPWT) is considered an effective wound treatment, but there are a number of issues that need to be addressed for improvements to be made. This review aimed to explore the literature relating to the pain and skin trauma that may be experienced during NPWT. A literature search was carried out using the following databases: Academic Search Complete, CINAHL, PsychINFO, MEDLINE and PsyARTICLES. A total of 30 articles were reviewed. Studies reported varying levels of pain in patients undergoing NPWT, with certain treatment factors affecting the level of pain, such as the NPWT system and the dressing/filler used. Similarly, although there is much less research exploring NPWT-related trauma, findings suggest that dressing and filler type may impact on whether trauma occurs. However, further research needs to consider the different stages of NPWT and how pain and trauma can be minimised during the whole procedure. As both pain and skin trauma impact on the patient's well-being and on wound healing, it is essential that research further explores the factors that may affect the experience of pain and trauma, so as to inform developments in wound care. © 2013 The Authors.

The aims of this project were to explore the factors contributing to poor sleep quality at 1 to 3 years after heart transplantation (post-HT), and to explore economic problems and social support for HT recipients (HTRs). This study used a cross-sectional retrospective triangulation approach combining qualitative and quantitative research method designs. Quantitative data included data from the visual analog scale and the Taiwanese version of the World Health Organization Quality of Life questionnaire. Qualitative data were derived from questions that explored physiological, psychological, and economic factors contributing to poor sleep quality postprocedure for HTRs. Sixty-four subjects (81% male, 19% female) participated in this research. Their ages ranged from 20 to 70 (M = 46.88 ± 12.12) years old. Their post-HT timeframe ranged from 1 to 4.10 years; 33% received preoperative extracorporeal membrane oxygenation support. Sleeping disturbances were reported by 72.7% of subjects after HT. Poor sleeping quality at 2 to 3 years post-HT (P = .028) was a complaint, and was worse than at 1 to 2 years post-HT (P = .008). Six physiological (62.5%) and 3 psychological (37.5%) contributing factors were further identified in qualitative interviews. Physiological factors were the major causes affecting their sleep quality 2 to 3 years after HT, whereas psychological factors arose from various family roles, responsibilities, and economic-related pressures. Medical teams should find the causes that lead to sleep disturbances and use the findings to improve HTR sleep quality. When the family financial status is affected, these teams should offer assistance and suggestions for patients who are unable to work due to post-HT physical decline. Establishing and providing good family support systems or patient support groups may allow patients to obtain physical, psychological, and spiritual comfort. Copyright © 2014 Elsevier Inc.

Paraprofessionals serve a primary role in supporting students with disabilities in the classroom, which necessitates teachers' supervision as a means to improve their practice. Yet, little is known regarding what factors affect teacher supervision. We sought to identify how paraprofessional competence and classroom type affected the levels of teacher direction. We administered an adapted version of the Paraprofessional Needs, Knowledge & Tasks Survey and the Survey for Teachers Supervising Paraprofessionals to teachers supervising paraprofessionals in elementary schools. Structural Equation Modeling was used to examine the link between paraprofessional competence and classroom factors affecting the level of teacher supervision. Our results indicated that when teachers perceived paraprofessionals as being more skilled, they provided more supervision, and when more supervision was provided the less they thought paraprofessionals should be doing their assigned tasks. Additionally, paraprofessionals working in classrooms with more students with mild disabilities received less supervision than paraprofessionals working in classrooms with more students with moderate-to-severe disabilities. Those paraprofessionals in classrooms serving mostly children with mild disabilities were also perceived as having lower levels of skill competence than those serving in classrooms with students with more moderate-to-severe disabilities. By understanding the factors that affect teacher supervision, policy and professional development opportunities can be refined/developed to better support both supervising teachers and paraprofessionals and, in turn, improve the outcomes of children with disabilities.

Disasters do not affect people equally; the impact of disasters on the lives of women is different from other groups of a community. Women's fundamental rights to health and safety are violated after disasters. The authors of this study aimed to explore various factors of women's health with reference to previous natural disasters in Iran. A qualitative approach using in-depth unstructured interviews and field observations was employed to explore women's health factors in the affected regions. A total of 22 participants affected by disasters, as well as key informants, were interviewed applying the purposeful sampling method. Data were collected in 2014 in three provinces, including East Azerbaijan, Bushehr, and Mazandaran. A content analysis using the Graneheim approach was performed for analyzing the transcribed interviews. Two themes and four categories were extracted from the data. The themes that emerged included psycho-physical effects and women's health status. Physical and psycho-emotional effects and reproductive and environmental health effects were the four emergent categories. The findings implied that managing women's health challenges may result in reducing the distressing effects of disaster. These findings support identification and application of the mechanisms by which women's well-being in physical, mental, reproductive, and environmental aspects can be protected after disasters.

Objective Previous studies have highlighted the short career intentions and high attrition rates of physiotherapists from the profession. The aim of the present study was to examine the job satisfaction and attrition rates of early career physiotherapists graduating from one Western Australian university. Methods A self-administered online survey was conducted of 157 Notre Dame physiotherapy graduates (2006-2012), incorporating a job satisfaction rating scale. Results Results showed that lowered job satisfaction was related to working in the cardiorespiratory area of physiotherapy and working in multiple jobs since graduation. The majority of graduates did not predict a long-term career in physiotherapy, highlighting a lack of career progression and limited scope of practice as influential factors. Conclusions Job satisfaction in early career physiotherapists varies across different clinical areas of practice related to several factors, including challenge and flexibility. New roles in the profession, including extended scope roles, may impact on the future job satisfaction of physiotherapists. Further studies are needed to explore the effect of these roles on workforce trends, including attrition rates. What is known about the topic? Physiotherapists predict careers of 10 years or less on entry into the profession. No previous studies have explored the individual factors influencing job satisfaction in early career physiotherapists across different clinical settings. What does this paper add? This study highlights specific factors influencing the job satisfaction of early career physiotherapists, including clinical area of practice. Physiotherapists working in the cardiorespiratory area were less satisfied, as were physiotherapists undertaking multiple positions since graduation. What are the implications for practitioners? This study informs employers and workforce planners on the factors affecting job satisfaction in early career physiotherapists. In addition, knowledge of issues affecting job satisfaction in the early career stage may assist educational institutions in their preparation of graduates for the future health workforce.

Professional ethics refers to the use of logical and consistent communication, knowledge, clinical skills, emotions and values in nursing practice. This study aimed to explore and describe factors that affect professional ethics in nursing practice in Iran. This qualitative study was conducted using conventional content analysis approach. Thirty nurses with at least 5 years of experience participated in the study; they were selected using purposive sampling. Data were collected through semi-structured interviews and analyzed using thematic analysis. After encoding and classifying the data, five major categories were identified: individual character and responsibility, communication challenges, organizational preconditions, support systems, educational and cultural development. Awareness of professional ethics and its contributing factors could help nurses and healthcare professionals provide better services for patients. At the same time, such understanding would be valuable for educational administrators for effective planning and management.

Attention-deficit hyperactivity disorder (ADHD) causes difficulties with hyperactivity, impulsivity and inattention. Treatment of ADHD includes both medication and non-pharmacological options. Knowledge of treatment preferences by young adults with ADHD is sparse. The objective of this study was to explore the beliefs and experiences of young adults with ADHD related to their medication treatment decisions. Data were collected in Denmark in 2016 through a focus group and individual in-depth interviews. Conventional content analysis was used. Ten young adults with ADHD (22-to 29-year-old) participated. Three major themes were identified: (1) the patient’s right to choose concerning ADHD medicine; (2) the patient’s decision of whether or not to treat ADHD with medication; and (3) factors affecting the patient’s decision on whether to take ADHD medication or not. The latter theme contained 15 factors, which were distributed across three levels: individual, between-individuals, and societal. The dominant factors were increasing quality of life and improving oneself e.g., improving social skills. For counselling at the pharmacy and by prescribers, it is important to be aware of the different factors that affect young adult patients’ decisions on whether to take ADHD medication or not. This knowledge will aid to understand reasons for non-adherence and to determine appropriate treatment for the individual patient.

Interprofessional collaboration within Canadian integrative healthcare clinics: Key components.

Research shows that interprofessional collaboration has become an important factor in the implementation of effective healthcare models. To date, the literature has not focused on the collaboration between medical doctors and complementary and alternative medicine (CAM) healthcare practitioners, an example of interdisciplinary collaboration called integrative healthcare (IHC). Drawing on in-depth, semi-standardized interviews conducted with 21 practitioners working in Canadian IHC clinics, this paper explored and interpreted how IHC is experienced by those working in Canadian IHC clinics. The interview questions and analysis were guided by the Input, Process, Output conceptual framework drawn from the organizational management theory (McGrath, J. E. (1964). Social psychology: A brief introduction. New York: Holt, Rinehart and Winston.) to study collaboration within teams. We found that constructs contributing to collaboration included practitioners' attitudes and educational background, as well as external factors such as the healthcare system and financial pressures. Major processes affecting collaboration included communication, patient referral and power relationships. These determinants of collaboration were found to result in learning opportunities for practitioners, modified burden of work and ultimately, higher affective commitment toward the clinic. These constructs serve as a guide for further investigation of interprofessional collaboration within an IHC clinic. This exploration of interprofessional collaboration in IHC identified a broad array of key factors associated with interprofessional collaboration. These factors are critical to better understand the functioning of IHC clinics, and provide guidance for creation or maintenance of successful clinics.

Our study explores perceptions of the caregiver support for mental health service users (MHSUs) in a low- to middle-income country setting. We conducted in-depth individual interviews with 16 MHSUs and their treatment partners/caregivers from a treatment partner and text-message intervention study. Treatment partners/caregivers felt obligated to care for MHSUs, but had a limited understanding of mental illness. They found supporting adherence to treatment difficult due to a number of factors including violence, food insecurity and substance abuse. Socioeconomic and environmental factors affecting the lives of MHSUs have impact on caregiver relationships with MHSUs in their care. © The Author(s) 2016.

Factors Affecting 25-Hydroxyvitamin D Concentration in Response to Vitamin D Supplementation

Sun exposure is the main source of vitamin D. Due to many lifestyle risk factors vitamin D deficiency/insufficiency is becoming a worldwide health problem. Low 25(OH)D concentration is associated with adverse musculoskeletal and non-musculoskeletal health outcomes. Vitamin D supplementation is currently the best approach to treat deficiency and to maintain adequacy. In response to a given dose of vitamin D, the effect on 25(OH)D concentration differs between individuals, and it is imperative that factors affecting this response be identified. For this review, a comprehensive literature search was conducted to identify those factors and to explore their significance in relation to circulating 25(OH)D response to vitamin D supplementation. The effect of several demographic/biological factors such as baseline 25(OH)D, aging, body mass index(BMI)/body fat percentage, ethnicity, calcium intake, genetics, oestrogen use, dietary fat content and composition, and some diseases and medications has been addressed. Furthermore, strategies employed by researchers or health care providers (type, dose and duration of vitamin D supplementation) and environment (season) are other contributing factors. With the exception of baseline 25(OH)D, BMI/body fat percentage, dose and type of vitamin D, the relative importance of other factors and the mechanisms by which these factors may affect the response remains to be determined.

Exploring Dimensionality of Effortful Control Using Hot and Cool Tasks in a Sample of Preschool Children

PubMed Central

Allan, Nicholas P.; Lonigan, Christopher J.

2015-01-01

Effortful control (EC) is an important developmental construct associated with academic performance, socioemotional growth, and psychopathology. EC, defined as the ability to inhibit or delay a prepotent response typically in favor of a subdominant response, undergoes rapid development during children’s preschool years. Research involving EC in preschool children can be aided by ensuring that the measured model of EC matches the latent structure of EC. Extant research indicates that EC may be multidimensional, consisting of hot (affectively salient) and cool (affectively neutral) dimensions. However, there are several untested assumptions regarding the defining features of hot EC. Confirmatory factor analysis was used in a sample of 281 preschool children (Mage = 55.92 - months, SD = 4.16; 46.6% male and 53.4% female) to compare a multidimensional model composed of hot and cool EC factors with a unidimensional model. Hot tasks were created by adding affective salience to cool tasks so that hot and cool tasks varied only by this aspect of the tasks. Tasks measuring EC were best described by a single factor and not distinct hot and cool factors, indicating that affective salience alone does not differentiate between hot and cool EC. EC shared gender-invariant associations with academic skills and externalizing behavior problems. PMID:24518050

Patient involvement in safe delivery planning is considered important yet not widely practiced. The present study aimed at identifythe factors that affect patient involvementin safe delivery, as recommended by parturient women. This study was part of a qualitative research conducted by content analysis method and purposive sampling in 2013.The data were collected through 63 semi-structured interviews in4 hospitalsand analyzed using thematic content analysis. The participants in this research were women before discharge and after delivery. Findings were analyzed using Colaizzi's method. Four categories of factors that could affect patient involvement in safe delivery emerged from our analysis: patient-related (true and false beliefs, literacy, privacy, respect for patient), illness-related (pain, type of delivery, patient safety incidents), health care professional-relatedand task-related factors (behavior, monitoring &training), health care setting-related (financial aspects, facilities). More research is needed to explore the factors affecting the participation of mothers. It is therefore, recommended to: 1) take notice of mother education, their husbands, midwives and specialists; 2) provide pregnant women with insurance coverage from the outset of pregnancy, especially during prenatal period; 3) form a labor pain committee consisting of midwives, obstetricians, and anesthesiologists in order to identify the preferred painless labor methods based on the existing facilities and conditions, 4) carry out research on observing patients' privacy and dignity; 5) pay more attention on the factors affecting cesarean.

Sociostructural factors influencing health behaviors of urban African-American men.

Plowden, Keith O; Young, Anthony E

2003-06-01

African-American men are suffering disproportionately from most illnesses. Seemingly, action is needed if health disparities that disproportionately affect African-American men as compared to their White and female counterparts are to be reduced or eliminated. An important step in decreasing common health disparities evidenced among African-American men is to understand social factors that act as motivators and barriers to seeking care for most of this vulnerable population. Following a constructionist epistemology, this study used ethnography to explore social structure factors that motivate urban African-American men to seek care. Leininger's Culture Care Diversity and Universality Theory guided this study. Qualitative interviews were conducted with urban African-American men and other individuals in the community to explore understanding, attitudes, and beliefs about health. Critical issues examined included social factors associated with health seeking behaviors. Themes that emerged from these data indicated that critical social factors include: 1) Kinship/significant others; 2) accessibility of resources; 3) ethnohealth belief; and 4) accepting caring environment. The data also indicated a relationship between these social factors and health seeking behaviors of urban African-American men.

Affect asymmetry and comfort food consumption.

PubMed

Dubé, Laurette; LeBel, Jordan L; Lu, Ji

2005-11-15

It is proposed that the emotional triggers of comfort food consumption can reliably be predicted by factors tied to affect asymmetry whereby negative affects dominate one's experience, decision making and behaviors in some instances while positive emotions prevail in others. Specifically, we relate three of these factors (age, gender, and culture) to differences in the emotional triggers of comfort food consumption and we further explore the possibility that the type of food eaten during comfort-seeking episodes can also be tied to affect asymmetry. Two hundred and seventy-seven participants completed a web-based survey conducted to assess the emotional antecedents and consequences of comfort food consumption. Consistent with expectations, results indicate that men's comfort food consumption was motivated by positive emotions whereas women's consumption was triggered by negative affects. Consumption of comfort foods alleviated women's negative emotions but also produced guilt. Positive affect was a particularly powerful trigger of comfort food consumption for older participants and for participants with French cultural background. Younger participants and participants with English background reported more intense negative emotions prior to consuming comfort foods. Foods high in sugar and fat content were more efficient in alleviating negative affects whereas low-calorie foods were more efficient in increasing positive emotions.

Curiosity Killed the Cocktail? Curiosity, Sensation Seeking, and Alcohol-related Problems in College Women

PubMed Central

Lindgren, Kristen P.; Mullins, Peter M.; Neighbors, Clayton; Blayney, Jessica A.

2010-01-01

Curiosity, composed of two factors: exploration and absorption, has been previously associated with life satisfaction, life meaningfulness, and enhanced positive affect. It also shares some overlap with sensation seeking, which has been linked to alcohol use and other addictive behaviors. The present research explored the association between curiosity and college women’s problematic drinking in the context of sensation seeking. Participants (79 women) completed questionnaires measuring curiosity, sensation seeking, alcohol consumption, and consequences related to alcohol consumption. A zero-inflated negative binomial model indicated that curiosity and sensation seeking accounted for unique variance in alcohol-related problems after controlling for drinking. The curiosity factors had opposing relationships to alcohol-related problems: higher scores on absorption were associated with more alcohol related problems whereas higher scores on exploration were associated with fewer alcohol related problems. Should findings be replicated, the curiosity factors may represent additional prevention and intervention targets. Future directions for research about curiosity and drinking and for the inclusion of positive psychology constructs in addictive behaviors research are discussed. PMID:20080358

Error framing effects on performance: cognitive, motivational, and affective pathways.

PubMed

Steele-Johnson, Debra; Kalinoski, Zachary T

2014-01-01

Our purpose was to examine whether positive error framing, that is, making errors salient and cuing individuals to see errors as useful, can benefit learning when task exploration is constrained. Recent research has demonstrated the benefits of a newer approach to training, that is, error management training, that includes the opportunity to actively explore the task and framing errors as beneficial to learning complex tasks (Keith & Frese, 2008). Other research has highlighted the important role of errors in on-the-job learning in complex domains (Hutchins, 1995). Participants (N = 168) from a large undergraduate university performed a class scheduling task. Results provided support for a hypothesized path model in which error framing influenced cognitive, motivational, and affective factors which in turn differentially affected performance quantity and quality. Within this model, error framing had significant direct effects on metacognition and self-efficacy. Our results suggest that positive error framing can have beneficial effects even when tasks cannot be structured to support extensive exploration. Whereas future research can expand our understanding of error framing effects on outcomes, results from the current study suggest that positive error framing can facilitate learning from errors in real-time performance of tasks.

Andrews, Mary E; Stewart, Norma J; Morgan, Debra G; D'Arcy, Carl

2012-05-01

To explore gender differences and similarities on personal, employment and work-life factors and predictors of job satisfaction among registered nurses in rural and remote Canada. Research suggests that men and women are attracted to nursing for different reasons, with job security, range of employment opportunities and wages being important for male nurses. Using data from a large national survey of registered nurses in rural and remote Canada, descriptive and multiple linear regression analyses were used to identify gender differences and similarities. A larger proportion of male nurses reported experiencing aggression in the workplace. Age, annual gross income and colleague support in medicine were not found to be predictors of work satisfaction for the male nurses, although they were for women. There are more similarities than differences between male and female registered nurses in factors that affect job satisfaction. Nursing management needs to increase their awareness of the potential for workplace aggression towards male registered nurses and to explore the perceptions of interpersonal interactions that affect satisfaction in the workplace. © 2011 Blackwell Publishing Ltd.

Exploring the relationship between volunteering and hospice sustainability in the UK: a theoretical model.

Scott, Ros; Jindal-Snape, Divya; Manwaring, Gaye

2018-05-02

To explore the relationship between volunteering and the sustainability of UK voluntary hospices. A narrative literature review was conducted to inform the development of a theoretical model. Eight databases were searched: CINAHL (EBSCO), British Nursing Index, Intute: Health and Life Sciences, ERIC, SCOPUS, ASSIA (CSA), Cochrane Library and Google Scholar. A total of 90 documents were analysed. Emerging themes included the importance of volunteering to the hospice economy and workforce, the quality of services, and public and community support. Findings suggest that hospice sustainability is dependent on volunteers; however, the supply and retention of volunteers is affected by internal and external factors. A theoretical model was developed to illustrate the relationship between volunteering and hospice sustainability. It demonstrates the factors necessary for hospice sustainability and the reciprocal impact that these factors and volunteering have on each other. The model has a practical application as an assessment framework and strategic planning tool.

What makes people read an online review? The relative effects of posting time and helpfulness on review readership.

PubMed

Lee, Jung

2013-07-01

This study explores the factors that make online customers select which reviews to read among the various ones on the Web. While most of literature on online consumer reviews has conveniently assumed that more helpful reviews would be read by more customers, no empirical study has tested whether the helpfulness assessment actually increases readership. Hence, this study explores various factors affecting consumer review readership and proposes that although helpfulness assessment promotes the readership of a review, the most dominant factor contributing to readership is the time of posting. A review posted late loses a significant chance of being read by consumers even if it is assessed as helpful by other readers. The hypotheses are tested using the data collected from Amazon.com , and the result of the study advises practitioners to display reviews in a manner that lessens the impact of posting time while enhancing the helpfulness voting systems.

Leadership, Knowledge Sharing, and Creativity: The Key Factors in Nurses' Innovative Behaviors.

PubMed

Kim, Sung-Jin; Park, Myonghwa

2015-12-01

This study identified the factors that affect the innovative behaviors of nurses at general hospitals based on their individual and organizational characteristics. The predictors of innovative nursing behaviors, such as self-leadership, individual knowledge sharing, creative self-efficacy, organizational knowledge sharing, and innovative organizational cultures, should be explored at individual and organizational level. This study administered a cross-sectional survey to 347 registered nurses working at 6 general hospitals (with >300 beds) in central South Korea. Data were collected using a self-report questionnaire and analyzed using structural equation modeling. Self-leadership, creative self-efficacy, and individual knowledge sharing directly affected individual innovative behaviors. Organizational knowledge sharing indirectly affected individual innovative behaviors, and this effect was mediated by an innovative organizational culture. This study contributes to the knowledge base regarding the effective management of individuals and organizations through innovative behavior; furthermore, it provides future directions for nursing interventions.

The impact of prescription charges on asthma patients is uneven and unpredictable: evidence from qualitative interviews.

PubMed

Schafheutle, Ellen I

2009-12-01

To explore whether, and how, prescription charges affect asthma patients' disease management behaviour. Thirty qualitative interviews. Interviewees were aged between 21 and 59, 21 were women, 24 were paying individual prescription charges, and six had prepayment certificates (PPCs). Most had a beta2-agonist 'reliever' and a steroid 'preventer' inhaler. Prescription charges posed affordability issues for some, and for two patients cost-related reduction in 'preventer' use affected asthma control negatively. Many described various ways of keeping medication cost down. Affordability issues, negative views on paying charges, and whether interviewees viewed their asthma medication as essential, were influential factors. Steroid inhalers were viewed more commonly as being less essential and affected by cost. The episodic nature of asthma meant that predicting benefit from PPCs was difficult. This study strengthens existing evidence that medication cost is a factor in asthma patients' management decisions, with a potential cost-related impact on asthma control.

Factors affecting the labor efficiency of hospital-based blood bank laboratories.

Lam, H C; Kominski, G F; Petz, L D; Sofaer, S

1994-09-01

A variety of financing mechanisms and managerial innovations have been developed in the past decade to control hospital costs. Some evidence suggests that those changes have not produced substantial improvements in labor efficiency among employees in the hospital's technical level, such as in the blood bank laboratories. This study measured labor efficiency in 40 hospital-based blood bank laboratories in Southern California during the year from July 1989 to June 1990 and explored the impact of financial, managerial, and operational factors on labor efficiency. With standardized output measures used in all blood bank laboratories, a wide variation of labor efficiency was found. Multivariate analyses indicate that the labor efficiency of blood bank employees was not influenced by organizational financial incentives, but was affected by the managerial styles of blood bank managers. Interpretation of the findings suggests that labor efficiency is affected by operational designs intended to improve responses to variable workloads and reduce slack time.

Information professionals' participation in interdisciplinary research: a preliminary study of factors affecting successful collaborations.

PubMed

Lorenzetti, Diane L; Rutherford, Gayle

2012-12-01

This pilot study explores the conditions that support or hinder information professionals' participation in interdisciplinary research teams. We undertook a preliminary grounded theory study investigating factors that impact on information professionals' participation in interdisciplinary research. Four biomedical information professionals working in academic universities and teaching hospitals in Canada participated in semi-structured interviews. Grounded theory methods guided the data collection and analysis. Participants identified the conditions that support or hinder research participation as belonging to four distinct overlapping domains: client-level factors including preconceptions and researcher resistance; individual-level factors such as research readiness; opportunities that are most often made not found; and organisational supports. Creating willingness, building preparedness and capitalising on opportunity appear crucial to successful participation in interdisciplinary research. Further exploration of the importance of educational, collegial and organisational supports may reveal additional data to support the development of a grounded theory regarding the facilitation of information professionals' engagement in interdisciplinary research. © 2012 The authors.

Impact of guided exploration and enactive exploration on self-regulatory mechanisms and information acquisition through electronic search.

PubMed

Debowski, S; Wood, R E; Bandura, A

2001-12-01

Following instruction in basic skills for electronic search, participants who practiced in a guided exploration mode developed stronger self-efficacy and greater satisfaction than those who practiced in a self-guided exploratory mode. Intrinsic motivation was not affected by exploration mode. On 2 post-training tasks, guided exploration participants produced more effective search strategies. expended less effort, made fewer errors, rejected fewer lines of search, and achieved higher performance. Relative lack of support for self-regulatory factors as mediators of exploration mode impacts was attributed to the uninformative feedback from electronic search, which causes most people to remain at a novice level and to require external guidance for development of self-efficacy and skills. Self-guided learning will be more effective on structured tasks with more informative feedback and for individuals with greater expertise on dynamic tasks.

Late adolescent female smoking.

PubMed

Seguire, M; Chalmers, K I

2000-06-01

Although there have been intense efforts to reduce the prevalence of cigarette smoking in the past three decades, smoking continues to be a critical public health problem. An area of particular concern is the increasing number of young women who are smoking. Gender specific research usually does not examine factors affecting smoking behaviours. Information on late adolescent female smoking is not readily found in the literature. The aims of this study were to explore the smoking patterns and processes of late adolescent females and to explore factors which may or may not be helpful in assisting them to stop smoking. A qualitative ethnographic approach was used to uncover the perceptions of 25 adolescent girls of their behaviour. Data were collected using tape-recorded semi-structured interviews and a questionnaire. Items for the questionnaire were derived from the Manitoba Youth Smoking Survey and from the Fagerstrorn Nicotine Tolerance Scale. Qualitative analysis resulted in four stories about smoking: the start story, the smoking story, the quit story, and the looking to the future story. Although many of the findings are congruent with the existing literature, much of the data reflected the purposive nature of smoking in late adolescent girls. Study findings support the need for holistic approaches to health promotion to ameliorate factors affecting smoking behaviour.

Exploring the Influence of Nursing Work Environment and Patient Safety Culture on Missed Nursing Care in Korea.

Kim, Kyoung-Ja; Yoo, Moon Sook; Seo, Eun Ji

2018-04-20

This study aimed to explore the influence of nurse work environment and patient safety culture in hospital on instances of missed nursing care in South Korea. A cross-sectional design was used, in which a structured questionnaire was administered to 186 nurses working at a tertiary university hospital. Data were analyzed using descriptive statistics, t-test or ANOVA, Pearson correlation and multiple regression analysis. Missed nursing care was found to be correlated with clinical career, nursing work environment and patient safety culture. The regression model explained approximately 30.3 % of missed nursing care. Meanwhile, staffing and resource adequacy (β = -.31, p = .001), nurse manager ability, leadership and support of nurses (β = -.26, p = .004), clinical career (β = -.21, p = .004), and perception on patient safety culture within unit (β = -.19, p = .041) were determined to be influencing factors on missed nursing care. This study has significance as it suggested that missed nursing care is affected by work environment factors within unit. This means that missed nursing care is a unit outcome affected by nurse work environment factors and patient safety culture. Therefore, missed nursing care can be managed through the implementation of interventions that promote a positive nursing work environment and patient safety culture. Copyright © 2018.

2014-03-01

One of the most important rehabilitation goals is to return people with disabilities to paid employment. The purposes of this study were (1) to explore employment status and (2) to identify factors that may affect the employment outcomes of people with disabilities who received Disability Employment Services (DES). A retrospective study was conducted on clients who commenced and closed DES between January 2008 and December 2010 in a metropolitan city in Taiwan, using the files from the National Vocational Rehabilitation Services Documentary System. Sixty-nine percent (1,684 out of 2,452) of the clients in this study were engaged in paid employment after receiving DES. Logistic regression analyses indicated that clients with no psychiatric disability or mild impairment and with useful vocational qualifications, typical work experience, more post-employment services, and less pre-employment services were associated with a higher rate of successful employment outcomes. This study provides empirical evidence of the association between person- and DES-related factors and the employment outcomes of people with disabilities. Future improvements in health, school-to-work transition services, and vocational rehabilitation for people with disabilities should place more emphasis on providing work-based work experience, professional vocational training, access to college/professional education, career exploration, effective supported employment services, and other post-employment services.

The role of life histories and trophic interactions in population recovery.

PubMed

Audzijonyte, Asta; Kuparinen, Anna

2016-08-01

Factors affecting population recovery from depletion are at the focus of wildlife management. Particularly, it has been debated how life-history characteristics might affect population recovery ability and productivity. Many exploited fish stocks have shown temporal changes towards earlier maturation and reduced adult body size, potentially owing to evolutionary responses to fishing. Whereas such life-history changes have been widely documented, their potential role on stock's ability to recover from exploitation often remains ignored by traditional fisheries management. We used a marine ecosystem model parameterized for Southeastern Australian ecosystem to explore how changes towards "faster" life histories might affect population per capita growth rate r. We show that for most species changes towards earlier maturation during fishing have a negative effect (3-40% decrease) on r during the recovery phase. Faster juvenile growth and earlier maturation were beneficial early in life, but smaller adult body sizes reduced the lifetime reproductive output and increased adult natural mortality. However, both at intra- and inter-specific level natural mortality and trophic position of the species were as important in determining r as species longevity and age of maturation, suggesting that r cannot be predicted from life-history traits alone. Our study highlights that factors affecting population recovery ability and productivity should be explored in a multi-species context, where both age-specific fecundity and survival schedules are addressed simultaneously. It also suggests that contemporary life-history changes in harvested species are unlikely to increase their resilience and recovery ability. © 2016 Society for Conservation Biology.

Putting performance in context: the perceived influence of environmental factors on work-based performance.

PubMed

Stroud, Lynfa; Bryden, Pier; Kurabi, Bochra; Ginsburg, Shiphra

2015-10-01

Context shapes behaviours yet is seldom considered when assessing competence. Our objective was to explore attending physicians' and trainees' perceptions of the Internal Medicine Clinical Teaching Unit (CTU) environment and how they thought contextual factors affected their performance. 29 individuals recently completing CTU rotations participated in nine level-specific focus groups (2 with attending physicians, 3 with senior and 2 with junior residents, and 2 with students). Participants were asked to identify environmental factors on the CTU and to describe how these factors influenced their own performance across CanMEDS roles. Discussions were analyzed using constructivist grounded theory. Five major contextual factors were identified: Busyness, Multiple Hats, Other People, Educational Structures, and Hospital Resources and Policies. Busyness emerged as the most important, but all factors had a substantial perceived impact on performance. Participants felt their performance on the Manager and Scholar roles was most affected by environmental factors (mostly negatively, due to decreased efficiency and impact on learning). In complex workplace environments, numerous factors shape performance. These contextual factors and their impact need to be considered in observations and judgements made about performance in the workplace, as without this understanding conclusions about competency may be flawed.

A review of affecting factors on sexual satisfaction in women.

2014-12-01

Sex is a complex, important and sensitive issue in human being and interwoven with the whole of human existence. Given the serious changes in attitude, function and behavior in sex, the need to address sexual function, especially sexual satisfaction, is felt completely. Sexual satisfaction has a very important role in creating marital satisfaction and any defect in sexual satisfaction is significantly associated with risky sexual behaviors, serious mental illness, social crimes and ultimately divorce. The aim of this study was to explore affecting factors on sexual satisfaction in women based on an overview in scientific database. In this narrative review the researchers searched MEDLINE database, Google Scholar and Science Direct as well as Persian database like Scientific Information Database with search terms of sexual satisfaction and sexual function, restricted to English/ Persian language, during the 20 years ago. Then those articles written by renowned experts were selected. In this regard, 57 articles have been reviewed, which 30 articles related to this research have been extracted. The findings were divided in to four categories including: Demographic factors, Pathophysiological factors, Psychological factors and Sociocultural factors. Sexuality, especially sexual intimacy is sophisticated and yet elegant affair that the other persons has different definitions and different functions. Discrepancies in the results of the studies show that analysis of factors affecting sexual satisfaction regardless of the women's' sociocultural context, religious beliefs, and personal attitudes is undoubtedly inefficient, unscientific and irrational.

Exploring factors affecting owners' trust of contractors in construction projects: a case of China.

PubMed

Tai, Shuangliang; Sun, Chengshuang; Zhang, Shoujian

2016-01-01

It has been found that a low level of trust among members of a construction project team leads to poor performance in China. Many researchers have described the challenges, consequently advocating partnering as an attractive approach for more valuable cooperation. Because substantial investments have been poured into construction projects since the year 2000, trust research will improve the performance of construction projects and will be meaningful to the Chinese construction industry. The purpose of this paper is to investigate the attributes affecting owners' trust of contractors, to understand the potential properties of these factors, and to rank the factors in order of importance. Twenty-four attributes are identified from a literature review. Supported by qualitative reviews, a questionnaire is conducted to obtain relevant data, and 168 valid responses are obtained for data analysis. Principal component analysis (PCA) is employed to find the factor structure of the identified trust attributes. By the method of PCA, the attributes are extracted into eight factors, including interaction history, information sharing and communication, contract and institution, relation-specific investment, reputation, integrity, competence, and opportunistic behaviour. The value and originality of this paper are embodied in using PCA to understand the various attribute groupings and to illuminate trust impact factors in the Chinese context. When they understand the critical factors affecting trust better, owners and contractors can devise more appropriate strategies to improve performance.

Hand and finger dexterity as a function of skin temperature, EMG, and ambient condition.

Chen, Wen-Lin; Shih, Yuh-Chuan; Chi, Chia-Fen

2010-06-01

This article examines the changes in skin temperature (finger, hand, forearm), manual performance (hand dexterity and strength), and forearm surface electromyograph (EMG) through 40-min, 11 degrees C water cooling followed by 15-min, 34 degrees C water rewarming; additionally, it explores the relationship between dexterity and the factors of skin temperature, EMG, and ambient condition. Hand exposure in cold conditions is unavoidable and significantly affects manual performance. Two tasks requiring gross and fine dexterity were designed, namely, nut loosening and pin insertion, respectively. The nested-factorial design includes factors of gender, participant (nested within gender), immersion duration, muscle type (for EMG), and location (for skin temperature). The responses are changes in dexterity, skin temperature, normalized amplitude of EMG, and grip strength. Finally, factor analysis and stepwise regression are used to explore factors affecting hand and finger dexterity. Dexterity, EMG, and skin temperature fell with prolonged cooling, but the EMG of the flexor digitorum superficialis remained almost unchanged during the nut loosening task. All responses but the forearm skin temperature recovered to the baseline level at the end of rewarming. The three factors extracted by factor analysis are termed skin temperature, ambient condition, and EMG. They explain approximately two thirds of the variation of the linear models for both dexterities, and the factor of skin temperature is the most influential. Sustained cooling and warming significantly decreases and increases finger, hand, and forearm skin temperature. Dexterity, strength, and EMG are positively correlated to skin temperature. Therefore, keeping the finger, hand, and forearm warm is important to maintaining hand performance. The findings could be helpful to building safety guidelines for working in cold environments.

One of the challenges for treating pre-eclampsia and preventing further deterioration is determining how best to enable early detection. If women or their partners and families are able to raise early warnings about potential signs and symptoms of pre-eclampsia in pregnancy, birth and in the postnatal period, women may be able to receive earlier intervention to prevent severe pre-eclampsia from developing. The aim of this study was to improve understanding of factors affecting the ability of women to recognise symptoms and signs of pre-eclampsia/eclampsia and seek appropriate medical help and factors affecting health care professionals' responses to women and their families who 'speak up' about early warning signs and symptoms. A narrative synthesis was conducted of evidence relevant to address the research question. The following electronic data bases were searched for qualitative studies which met inclusion criteria from January 1980 to April 2016; Medline, CINAHL, HMIC, PsycINFO, Embase, BNI, ASSIA, Scopus, Maternity and Infant Care, Web of Science, Google Scholar, Cochrane, JBI and IBSS with the support of an Information Service Consultant. Following thematic analysis, three themes were identified; 1: Women's understanding and knowledge of pre-eclampsia/eclampsia; 2: Factors affecting help seeking behaviour from perspectives of women and their families'; 3: Factors affecting staff response. There was widespread lack of knowledge and understanding of signs and symptoms of pre-eclampsia/eclampsia among women and their families, with some women not exhibiting signs and symptoms of pre-eclampsia or unable to distinguish them from 'normal' pregnancy changes. Women and their families not only need to be made aware of signs and symptoms of pre-eclampsia/eclampsia but also require information on the most effective ways to seek urgent medical assessment and care. Some women did not experience prodromal signs and symptoms, which raises concerns about how women and families can detect early onset, and is an issue which needs further exploration. There is very limited research exploring clinical staff response to women who raise concerns about their health when experiencing symptoms and signs of pre-eclampsia/eclampsia with further research needed if safety and quality of care are to be improved.

The boom in bike-sharing is receiving growing attention as societies become more aware of the importance of active non-motorized traffic modes. However, the low usage of this transport mode in China raises concerns. The primary objective of this study is to explore factors affecting bike-sharing usage and satisfaction degree of bike-sharing among the bike-sharing user population in China. Data were collected by a questionnaire survey in Ningbo. A bivariate ordered probit (BOP) model was developed to examine simultaneously those factors associated with both bike-sharing usage and satisfaction degree of bike-sharing among users. Marginal effects for contributory factors were calculated to quantify their impacts on the outcomes. The results showed that the BOP model can account for commonly shared unobserved characteristics within usage and satisfaction of bike-sharing. The BOP model results showed that the usage of bike-sharing was affected by gender, household bicycle/e-bike ownership, trip model, travel time, bike-sharing stations location, and users’ perception of bike-sharing. The satisfaction degree of bike-sharing was affected by household income, bike-sharing stations location, and users’ perception of bike-sharing. It is also found that bike-sharing usage and satisfaction degree are strongly correlated and positive in direction. The results can enhance our comprehension of the factors that affect usage and satisfaction degree of bike-sharing. Based on the results, some suggestions regarding planning, engineering, and public advocacy were discussed to increase the usage of bike-sharing in Ningbo, China. PMID:28934321

To explore nurses' self-assessments of power and their opinions regarding factors affecting power in Turkey using a cross-sectional, descriptive study. In order to safely and cost-effectively care for patients, nurses must perceive themselves as powerful and have the use and control of power resources. The study sample consisted of 297 nurses in six hospitals: two government hospitals, two university hospitals and two private hospitals. Data were collected using the Demographic Data Form and Power Question Form. Nurses regarded themselves as 'quite powerful' regarding persuasion (53.2%) and referent power (43.4%). Many nurses also regarded themselves as having positional power and 'quite powerful' regarding, reward (44.1%) and legitimate power (34.7%). Nurses saw themselves as least powerful in resource power (48.1%). Individual, educational and organisational factors were the main factors affecting personal and positional power sources. Turkish nurses regarded themselves as above average on being powerful in both the personal and positional power base but not in resource power. We recommend that nurses, educators and managers develop strategies to support nurses' power as a way to enhance the patient care outcomes. © 2014 John Wiley & Sons Ltd.

To explore the factors affecting the residual stones after percutaneous nephrolithotomy (PCNL) in patients with renal calculus. A retrospective analysis was performed for 1 200 patients who were affected by renal calculus and treated with PCNL between Jan 2008 and May 2014 in People's Hospital of Anyang City. Among those patients, 16 were diagnosed as bilateral renal stone and had two successive operations. The size, location and number of stones, previous history of surgery, the degree of hydronephrosis, urinary infection were included in the univariate analysis. Significant factors in univariate analysis were included in the multivariate analysis to determine factors affecting stone residual. A total of 385 cases developed stone residual after surgery. The overall residual rate was 31.7%. In univariate analysis, renal pelvis combined with caliceal calculus (P=0.006), stone size larger than 4 cm (P=0.005), stone number more than 4 (P=0.002), the amount of bleeding more than 200 ml (P=0.025), operation time longer than 120 minutes (P=0.028) were associated with an increased rate of stone residual. When subjected to the Cox multivariate analysis, the independent risk factors for residual stones were renal pelvis combined with caliceal calculus (P=0.049), stone size larger than 4 cm (P=0.038) and stone number more than 4 (P=0.018). Factors affecting the incidence of residual stones after PCNL are the size, location and number of stones. Larger size stone and the presence of renal pelvis combined with caliceal calculus are significantly associated with residual stones. Nevertheless, stone number less than 4 indicates an increased stone clearance rate.

Pretend play has a central role for children's development and psychological well-being. However, there is a paucity of standardized and valid measures specifically devoted to assess the core domains involved in play activities in preschool and primary school children. The Affect in Play Scale-Preschool (4–5 years) and the Affect in Play Scale-Preschool Extended Version (6–10 years) are semi-structured parallel tools designed to explore child's cognitive and affective processes using a standardized play task. The current study administered this 5-min play task to 538 Italian children aged 4–10. The purposes were to compare play abilities in boys vs. girls and in preschool vs. primary school children, to correlate pretend play with divergent thinking and to evaluate the structural validity of the measure along the considered age span. No differences, excepting for Organization, were found between boys and girls, whereas school age children reported higher play abilities then the younger ones. External validity was assessed using correlational analysis with the divergent thinking task (the Alternate Uses Test) for preschoolers and primary school-aged children, in line with findings from Manova. Construct validity, assessed through the Confirmatory Factor Analysis, showed good fits for the two-factor model with cognitive and affective factor for both the Affect in Play Scale-Preschool and its Extended Version. A multi-group factor analysis suggested a partial invariance of the two-factor model across preschool (4–5 years old) and primary school-aged (6–10 years old) children. Results supported the use of the Affect in Play Scale-Preschool and its Extended Version as adequate measures to assess the interplay of cognitive and affective skills in preschool and school age children. The discussion highlights clinical and research implications linked to the possibility to have a unique play task able to assess child's affective and cognitive abilities throughout a quite wide life span (from 4 to 10 years old).

Length of stay (LOS) is considered a key measure of emergency department throughput, and from the perspective of the patient, it is perceived as a measure of healthcare service quality. Prolonged LOS can be caused by various internal and external factors. This study examined LOS in the emergency department and explored the main factors that influence LOS and cause delay in patient care. Observations of 105 patients were performed over a 3-month period at the emergency room of a community urban hospital. Observers monitored patients from the moment of entrance to the department until discharge or admission to another hospital ward. Analysis revealed a general average total emergency department LOS of 438 min. Significant differences in average LOS were found between admitted patients (Mean = 544 min, SD = 323 min) and discharged patients (Mean = 291 min, SD = 286 min). In addition, nurse and physician change of shifts and admissions to hospital wards were found to be significant factors associated with LOS. Using an Ishikawa causal diagram, we explored various latent organizational factors that may prolong this time. The study identified several factors that are associated with high average emergency department LOS. High LOS may lead to increases in expenditures and may have implications for patient safety, whereas certain organizational changes, communication improvement, and time management may have a positive effect on it. Interdisciplinary methods can be used to explore factors causing prolonged emergency department LOS and contribute to a better understanding of them.

Volitional exploration and learning are key to adaptive behavior, yet their characterization remains a complex problem for cognitive science. Exploration has been posited as a mechanism by which motivation promotes memory, but this relationship is not well-understood, in part because novel stimuli that motivate exploration also reliably elicit changes in neuromodulatory brain systems that directly alter memory formation, via effects on neural plasticity. To deconfound interrelationships between motivation, exploration, and memory formation we manipulated motivational state prior to entering a spatial context, measured exploratory responses to the context and novel stimuli within it, and then examined motivation and exploration as predictors of memory outcomes. To elicit spontaneous exploration, we used the physical space of an art exhibit with affectively rich content; we expected motivated exploration and memory to reflect multiple factors, including not only motivational valence, but also individual differences. Motivation was manipulated via an introductory statement framing exhibit themes in terms of Promotion- or Prevention-oriented goals. Participants explored the exhibit while being tracked by video. They returned 24 hours later for recall and spatial memory tests, followed by measures of motivation, personality, and relevant attitude variables. Promotion and Prevention condition participants did not differ in terms of group-level exploration time or memory metrics, suggesting similar motivation to explore under both framing contexts. However, exploratory behavior and memory outcomes were significantly more closely related under Promotion than Prevention, indicating that Prevention framing disrupted expected depth-of-encoding effects. Additionally, while trait measures predicted exploration similarly across framing conditions, traits interacted with motivational framing context and facial affect to predict memory outcomes. This novel characterization of motivated learning implies that dissociable behavioral and biological mechanisms, here varying as a function of valence, contribute to memory outcomes in complex, real-life environments.

The aim of this study was to explore the factors influencing registered nurses' pursuit of postgraduate education in specialty nursing practice in Australia. Despite the increased requirement for postgraduate education for advanced practice, little has been reported on the contributory factors involved in the decision to undertake further education. The Nurses' Attitudes Towards Postgraduate Education instrument was administered to 1632 registered nurses from the Nurses and Midwives e-Cohort Study across Australia, with a response rate of 35.9% (n = 568). Data reduction techniques using principal component analysis with varimax rotation were used. The analysis identified a three-factor solution for 14 items, accounting for 52.5% of the variance of the scale: "facilitators," "professional recognition," and "inhibiting factors." Facilitators of postgraduate education accounted for 28.5% of the variance, including: (i) improves knowledge; (ii) increases nurses' confidence in clinical decision-making; (iii) enhances nurses' careers; (iv) improves critical thinking; (v) improves nurses' clinical skill; and (vi) increased job satisfaction. This new instrument has potential clinical and research applications to support registered nurses' pursuit of postgraduate education. © 2016 John Wiley & Sons Australia, Ltd.

Factors determining insulin requirements in women with type 1 diabetes mellitus during pregnancy: a review

PubMed Central

McIntyre, Harold David; Callaway, Leonie

2014-01-01

Most women with type 1 diabetes mellitus (T1DM) have increased insulin requirements during pregnancy. However, a minority of women have a fall in insulin requirements. When this occurs in late gestation, it often provokes concern regarding possible compromise of the feto-placental unit. In some centres, this is considered as an indication for delivery, including premature delivery. There are, however, many other factors that affect insulin requirements in pregnancy in women with type 1 diabetes mellitus and the decline in insulin requirements may represent a variant of normal pregnancy. If there is no underlying pathological process, expedited delivery in these women is not warranted and confers increased risks to the newborn. We will explore the factors affecting insulin requirements in gestation in this review. We will also discuss some novel concepts regarding beta-cell function in pregnancy. PMID:27512424

The relationship between multidimensional leadership and burnout among nursing staff.

Kanste, Outi; Kyngäs, Helvi; Nikkilä, Juhani

2007-10-01

The purpose was to explore the relationship between multidimensional leadership and burnout among nursing staff. There exists little research evidence of the relation between these phenomena. The study used a non-experimental survey design. The sample consisted of 601 nurses and nurse managers working in different health care organizations. Rewarding transformational leadership seems to protect particularly from depersonalization. Active management-by-exception protected from depersonalization and increased personal accomplishment. Passive laissez-faire leadership functioned as an exposing factor for emotional exhaustion as well as a decreasing factor for personal accomplishment. However, the employment status and the character of work tasks affected the connection between leadership and burnout. The relation between leadership and burnout is complex, affected by situational factors of leadership and the ambiguous nature of burnout. Nurses of various ages, at different stages of career development and participating in different work tasks require different kinds of leadership.

The use of complementary and alternative medicine (CAM) as a source of cure has gained much spectrum worldwide, despite skeptics and advocates of evidence-based practice conceptualized such therapies as human nostrum. This study aimed to explore the factors affecting CAM use among rural communities in Malaysia. A cross-sectional study was carried out on 288 occupants across four rural villages within the District of Selama, Perak, Malaysia. A survey that consisted of socio-economic characteristics, history of CAM use and the validated Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) were used. The prevalence of self-reported CAM use over the past one year was 53.1%. Multiple logistic regression analyses yielded three significant predictors of CAM use: monthly household income of less than MYR 2500, higher education level, and positive attitude towards CAM. Psycho-socioeconomic factors were significantly associated with CAM use among rural communities in Malaysia.

Psoriasis is a common cutaneous disease with multifactorial etiology including genetic and non-genetic factors, such as drugs, smoking, drinking, diet, infection and mental stress. Now, the role of the interaction between environmental factors and genetics are considered to be a main factor in the pathogenesis of psoriasis. However, it is a challenge to explore the mechanisms how the environmental factors break the body balance to affect the onset and development of psoriasis. In this article, we review the pathogenesis of psoriasis and summarize numerous clinical data to reveal the association between environmental factors and psoriasis. In addition, we focus on the mechanisms of environmental risk factors impact on psoriasis and provide a series of potential treatments against environmental risk factors. © 2017 Japanese Dermatological Association.

The gut microbiota exhibit diurnal compositional and functional oscillations that influence the host homeostasis. However, the upstream factors that affect the microbial oscillations remain elusive. Here, we focused on the potential impact of light exposure, the main factor that affects the host circadian oscillation, on the diurnal oscillations of intestinal microflora to explore the upstream factor that governs the fluctuations of the gut microbes. The gut microbiota of the mice that were underwent regular light/dark (LD) cycles exhibited a robust rhythm at both compositional and functional level, in all parts of the intestine. Comparably, constant darkness (Dark-Dark, DD) led to the loss of the rhythmic oscillations in almost all parts of the intestine. Additionally, the abundance of Clostridia in DD conditions was dramatically enhanced in the small intestine. Our data indicated light exposure is the upstream factor that governs the regular diurnal fluctuations of gut microbiota in vivo. Copyright © 2018 Elsevier Inc. All rights reserved.

Attitudes of children and adolescents toward persons who are deaf, blind, paralyzed or intellectually disabled.

de Laat, Stijn; Freriksen, Ellen; Vervloed, Mathijs P J

2013-02-01

This study aimed to explore Dutch students' attitudes toward deaf, blind, paralyzed or intellectually disabled persons and to determine whether age, self-esteem, gender, religion and familiarity with a disabled person have a significant effect on these attitudes. The attitudes of 200 high school and 144 university students were determined with two questionnaires, the CATCH and MAS. Only the CATCH was applicable with all four disabled groups. Two factors were found: behavior-positive affect and cognition-negative affect. With regard to the first factor respondents had more positive attitudes toward deaf, blind and paralyzed persons than toward intellectually disabled persons. The cognition and negative affect factor showed that respondents had more positive attitudes toward deaf and blind persons than toward paralyzed and intellectually disabled persons. Being older and familiarity with a disabled person had a significant positive effect on attitudes, while self-esteem and gender had only a partial effect and having religious beliefs was not a significant predictor in this study.

New accounting rules went into effect at the end of 1995 that are now starting to affect how medical practices must report income from equity and fixed income investments. This article explores the new accounting rules and considers the other factors that help practices determine investment strategies, including desired investment return, comfort with level of risk, appropriate time horizons, liquidity needs and legal restrictions. The author also presents an example that examines the different considerations that may affect an asset allocation decision, including endowments and operating reserve funds.

An exploration of the perceived factors that affect the learning and transfer of skills taught to student midwives.

PubMed

Longworth, Mary K

2013-08-01

the aim of this study was to examine the attitudes of student midwives towards skills training and practise. The objectives were to explore the factors in the skills laboratory environment and in clinical practice which affect how successfully student midwives transfer into clinical practice the various skills they have learnt in preparation for an Objective Structured Clinical Examination. a review of the background literature revealed that there were many variables related to successful transfer of skills in general but there appeared to be a gap around perceived factors affecting transfer of skills of student midwives. a mixed methods design was conducted using both questionnaires and semi-structured interviews between June and August 2010. questionnaires were administered to all midwifery students at one university in Wales. These were later followed by semi-structured interviews for 6 student midwives who were purposively selected from all year groups. the results from the questionnaires revealed that a majority of students had positive attitudes to educators and mentors and to their skills acquisition experience in the skills laboratory and to the available opportunities to practise in clinical practice. Although students believed in the transferability of skills from the laboratory setting to clinical practice, a majority thought that clinical practice provided them with a better opportunity to learn clinical skills. The semi-structured interviews demonstrated that facilitating factors in the skills laboratory included having adequate instruction as well as having a designated space. Hindering factors included unrealistic models and equipment. In clinical practice, facilitating factors included having the opportunities to practise skills and support and feedback from the mentor. Hindering factors included deficits in the student-mentor relationship. this study highlighted that midwifery students must be adequately prepared to carry out clinical skills competently and effectively. Educators and mentors must provide adequate support and feedback to promote transfer of knowledge and skills into the workplace to optimise high standards of care for women and their babies.

2013-01-01

The study explored beliefs about health and illness in Latin American migrants diagnosed with diabetes mellitus (DM) living in Sweden, and investigated the influence on health-related behavior including self-care and care-seeking behavior. Migrants are particularly affected in the diabetes pandemia. Beliefs about health and illness determine health-related behaviour and health but no studies have been found on Latin American migrants with DM. An explorative study design with focus-group interviews of nine persons aged 36-77 years from a diabetes clinic was used. Health was described from a pathogenetic or a salutogenetic perspective: 'freedom from disease or feeling of well-being', and being autonomous and able to work. Economic hardship due to expenses for medications and food for DM affected health. Individual factors such as diet, exercise and compliance with advice, and social factors with good social relations and avoidance of stress, often caused by having experienced severe events related to migrational experiences, were considered important for maintaining health and could cause DM. Disturbed relations to others (social factors), punishment by God or Fate (supernatural factors), intake of diuretics and imbalance between warmth and cold (natural factors) were also perceived as causes. A mix of biomedical and traditional explanations and active self-care behaviour with frequent use of herbs was found. It is important to assess the individual's beliefs, and health professionals, particularly nurses, should incorporate discussions of alternative treatments and other components of explanatory models and co-operate with social workers to consider influence of finances and migrational experiences on health.

2017-01-01

To understand whether patient-reported experiences with lung cancer may create teachable moments (TM) for their relatives as evidenced by shifts in their risk perceptions, affective response, and self-image and in turn, motivation to quit smoking. Patients at a comprehensive cancer center (n = 152) completed a survey within 6 months of lung cancer diagnosis to assess their cancer-related symptoms and openness and enumerated relatives who were smokers. Relative smokers (n = 218) then completed a survey assessing their risk perceptions, affective response, and self-image as a smoker related to the patient's diagnosis (TM mechanisms), and their motivation to quit smoking. Cross-sectional mediation and moderation analyses were conducted to explore the links between patient-reported experiences, and relatives' TM mechanisms, and motivation to quit smoking. Relative-reported affect was a significant mediator of the association between patient-reported symptoms and relative smoker's desire to quit. Relatives' self-image was a significant moderator of the association between patient-reported symptoms and relative smoker's desire to quit, such that patients' reported symptoms were associated with relatives' desire to quit only when the relative smoker reported a generally positive self-image as a smoker. No evidence was found for moderated mediation. However, the link between symptoms and negative affect was moderated by perceptions of risk. Whether smokers experience a family member's lung cancer as a TM is influenced by multiple interrelated cognitive and affective factors that warrant further exploration. Clearer understanding of these factors could inform how to re-invigorate and sustain this motivation to promote concrete actions toward smoking cessation. Copyright © 2015 John Wiley & Sons, Ltd.

Kotronoulas, Grigorios; Wengstrom, Yvonne; Kearney, Nora

2013-01-01

Sleep is increasingly recognized as an area of functioning that may be greatly affected in persons who are practically and emotionally involved in the care of patients with cancer. Clinician awareness is required to ensure that effective care for informal caregivers with sleep problems is provided. A 2-fold critical review of the published literature was conducted, which aimed at summarizing and critically analyzing evidence regarding sleep patterns of informal caregivers of adults with cancer and contributing factors to sleep-wake disturbances. Using a wide range of key terms and synonyms, 3 electronic databases (MEDLINE, CINAHL, EMBASE) were systematically searched for the period between January 1990 and July 2011. Based on prespecified selection criteria, 44 articles were pooled to provide evidence on sleep-impairing factors in the context of informal caregiving, 17 of which specifically addressed sleep patterns of caregivers of people with cancer. At least 4 of 10 caregivers may report at least 1 sleep problem. Short sleep duration, nocturnal awakenings, wakefulness after sleep onset, and daytime dysfunction seem to be the areas most affected irrespective of stage or type of disease, yet circadian activity remains understudied. In addition, despite a wide spectrum of potential sleep-impairing factors, underlying causal pathways are yet to be explored. More longitudinal, mixed-methods, and comparison studies are warranted to explore caregiver sleep disorders in relation to the gravity of the caregiving situation in the context of diverse types of cancer and disease severity.

Contextual Factors for Establishing Nursing Regulation in Iran: A Qualitative Content Analysis

Nejatian, Ahmad; Joulaei, Hassan

2018-01-01

ABSTRACT Background: Professional regulation is one of the strategies of the governments which protect the public’s right. Nursing practice is not an exception; hence, it is regulated to protect the public against nursing services’ adverse effects. Although modern nursing in Iran started from 100 years ago, documents show that there was no regulation mechanism for nursing in Iran till 2016. Hence, this study was conducted to illuminate the contextual factors affecting the nursing regulation process in Iran. Methods: To explore the contextual elements of late establishment of nursing registration as an important part of nursing regulation, we applied directed qualitative content analysis. For this purpose, all the historical events and related materials including articles published in scientific journals, gray literature, statements, news articles, and interviews in the period of 2006-2016 were reviewed and analyzed by expert panel and categorized in predetermined groups. Results: Pooled analysis data showed four contributing elements that affected the emerging nursing regulation in Iran. These elements include 1) cultural determinants, 2) structural determinants, 3) situational determinants, and 4) international or exogenous determinants. Conclusion: Nursing regulation is an important health policy issue in Iran which needs to be facilitated by contextual factors. These factors are complicated and country-specific. Political willingness should be accompanied by nursing association willingness to establish and improve nursing regulation. Other researches are recommended to explore actors and process and content of nursing regulation policy in Iran. PMID:29607341

The association between perceived distress tolerance and cannabis use problems, cannabis withdrawal symptoms, and self-efficacy for quitting cannabis: The explanatory role of pain-related affective distress.

Rates of cannabis use and related problems continue to rise, ranking as the third most common substance use disorder in the United States, behind tobacco and alcohol use. Past work suggests that perceived distress tolerance is related to several clinically significant features of cannabis use (e.g., coping-oriented use). However, there has been little exploration of the mechanisms that may underlie relations between perceived distress tolerance and cannabis use problems, withdrawal severity, and self-efficacy for quitting. The current study sought to examine the experience of pain, which frequently co-occurs with cannabis use (Ashrafioun, Bohnert, Jannausch, & Ilgen, 2015), as an underlying factor in the relation between perceived distress tolerance and cannabis related problems among 203 current cannabis-using adults (29.2% female, M = 37.7 years, SD = 10.2, 63% African American). Results indicated that perceived distress tolerance via pain related affective distress significantly predicted the severity of cannabis use problems (Pm = 0.60), degree of cannabis withdrawal (Pm = 0.39), and lower self-efficacy for quitting cannabis (Pm = 0.36). Future work may usefully explore the role of pain-related affective distress as a mechanistic factor in the context of perceived distress tolerance-cannabis relations. Copyright © 2018 Elsevier Ltd.

Background: Consideration of patient autonomy is an essential element in individualized, patient-centered, ethical care. Internal and external factors associated with patient autonomy are related to culture and it is not clear what they are in Iran. The aim of this study was to explore contextual factors affecting the autonomy of patients in Iranian hospitals. Materials and Methods: This was a qualitative study using conventional content analysis methods. Thirty-four participants (23 patients, 9 nurses, and 2 doctors) from three Iranian teaching hospitals, selected using purposive sampling, participated in semi-structured interviews. Unstructured observation and filed notes were other methods for data collection. The data were subjected to qualitative content analysis and analyzed using the MAXQDA-10 software. Results: Five categories and sixteen subcategories were identified. The five main categories related to patient autonomy were: Intrapersonal factors, physical health status, supportive family and friends, communication style, and organizational constraints. Conclusions: In summary, this study uncovered contextual factors that the care team, managers, and planners in the health field should target in order to improve patient autonomy in Iranian hospitals.

Genetic risk factors for intracranial aneurysm (IA) are not yet fully understood. Genomewide association studies have been successful at identifying common variants; however, the role of rare variation in IA susceptibility has not been fully explored. In this study, we report the use of whole exome sequencing (WES) in seven densely-affected families (45 individuals) recruited as part of the Familial Intracranial Aneurysm study. WES variants were prioritized by functional prediction, frequency, predicted pathogenicity, and segregation within families. Using these criteria, 68 variants in 68 genes were prioritized across the seven families. Of the genes that were expressed in IA tissue, one gene (TMEM132B) was differentially expressed in aneurysmal samples (n=44) as compared to control samples (n=16) (false discovery rate adjusted p-value=0.023). We demonstrate that sequencing of densely affected families permits exploration of the role of rare variants in a relatively common disease such as IA, although there are important study design considerations for applying sequencing to complex disorders. In this study, we explore methods of WES variant prioritization, including the incorporation of unaffected individuals, multipoint linkage analysis, biological pathway information, and transcriptome profiling. Further studies are needed to validate and characterize the set of variants and genes identified in this study.

The Icelandic economic collapse, smoking, and the role of labor-market changes.

Smoking is related to health deterioration through increased risk of various diseases. Changes in this health behavior could contribute to the documented health improvements during economic downturns. Furthermore, the reasons for changes in behavior are not well understood. We explore smoking behavior in Iceland before and after the sudden and unexpected economic crisis in 2008. Furthermore, to explore the mechanisms through which smoking could be affected we focus on the role of labor-market changes. Both real income and working hours fell significantly and economic theory suggests that such changes can affect health behaviors which in turn affect health. We use individual longitudinal data from 2007 to 2009, incidentally before and after the crisis hit. The data originates from a postal survey, collected by The Public Health Institute in Iceland. Two outcomes are explored: smoking participation and smoking intensity, using pooled ordinary least squares (OLS) and linear probability models. The detected reduction in both outcomes is not explained by the changes in labor-market variables. Other factors in the demand function for tobacco play a more important role. The most notable are real prices which increased in particular for imported goods because of the devaluation of the Icelandic currency as a result of the economic collapse.

Individual variation in behavioural plasticity: direct and indirect effects of boldness, exploration and sociability on habituation to predators in lizards.

PubMed

Little is known about the factors causing variation in behavioural plasticity and the interplay between personality and plasticity. Habituation to predators is a special case of behavioural plasticity. We investigated the direct and indirect effects of boldness, exploration and sociability traits on the habituation ability of Iberian wall lizards, considering exposure and sex effects. Individual boldness was consistent across several non-habituation contexts, but it did not significantly affect habituation. Exploration had a strong direct effect on habituation, with more exploratory individuals being able to habituate faster than less exploratory ones, probably because of their ability to assess risk better. Individual variation in habituation was also affected by sociability, but this was an indirect effect mediated by exposure to the predator. Less social individuals avoided refuges with conspecific cues, increasing exposure to the predator and eventually habituation. Finally, the direct effects of sex (females habituated faster than males) were opposite to its indirect effects through exposure. We conclude that risk assessment, instead of the proactivity-reactivity gradient usually considered in the literature, can affect behavioural plasticity through complex interactions between direct and indirect effects, including exploratory behaviour, degree of exposure to the predator and sex, which represent novel mechanisms generating inter-individual variation in plasticity.

Many researches had been conducted to enhance the properties of contact lens. Most of the research conducted discussed on the factors that affect the adhesion process to contact lenses, rate of contact lens contamination, and type of microbe that adhere on the contact lens surface and contact lens casing. Studies on the proposed strategies or technology that can be used to slower down the formation of bacteria on contact lens are being explored. New technologies or strategies to prevent or slow down the adhesion of bacteria on contact lens have become a priority in this area. This review paper covers two main aspects, namely factor that affect the bacteria adhesion on contact lens and also the introduction of plasma treatment as a potential method for contact lens treatment.

Squeezing blood from a stone: how income inequality affects the health of the American workforce.

Williams, Jessica Allia R; Rosenstock, Linda

2015-04-01

Income inequality is very topical-in both political and economic circles-but although income and socioeconomic status are known determinants of health status, income inequality has garnered scant attention with respect to the health of US workers. By several measures, income inequality in the United States has risen since 1960. In addition to pressures from an increasingly competitive labor market, with cash wages losing out to benefits, workers face pressures from changes in work organization. We explored these factors and the mounting evidence of income inequality as a contributing factor to poorer health for the workforce. Although political differences may divide the policy approaches undertaken, addressing income inequality is likely to improve the overall social and health conditions for those affected.

This paper empirically explores lots of students in college for their hierarchy of needs and incentives to learn, and finds the linear relationship between them. With the survey, it's be found that there are some kinds of factors influence the students needs order. The paper gives several diagrams to show these important factors which affect the college students' hierarchy of needs most. The paper also finds the change of the student' hierarchy of needs will affect the variety of incentives to learn. Then the paper develops a model for qualitative analyze this relationship. Numerical examples are used to demonstrate the performance of the model. With this model the correct and useful methods can be easily selected for students to incentive according to their types of hierarchy of needs.

2012-01-01

The structure of temperament traits in young children has been the subject of extensive debate, with separate models proposing different trait dimensions. This research has relied almost exclusively on parent-report measures. The present study used an alternative approach, a laboratory observational measure, to explore the structure of temperament in preschoolers. A 2-stage factor analytic approach, exploratory factor analyses (n = 274) followed by confirmatory factor analyses (n = 276), was used. We retrieved an adequately fitting model that consisted of 5 dimensions: Sociability, Positive Affect/Interest, Dysphoria, Fear/Inhibition, and Constraint versus Impulsivity. This solution overlaps with, but is also distinct from, the major models derived from parent-report measures. PMID:21859196

Research has found perceived discrimination to be a risk factor for mental health concerns among lesbian, gay, and bisexual (LGB) people, but less clarity exists linking perceived discrimination with well-being outcomes. Building from Meyer's (2003) minority stress model, the present study examined the links between perceived discrimination and the 3 components of subjective well-being: positive affect, negative affect, and life satisfaction. Self-esteem and stigma consciousness were explored as empirically and theoretically implied moderators. In a sample of 368 LGB people, structural equation modeling results suggested that discrimination was not significantly associated with positive affect or life satisfaction but had a significant positive relation with negative affect. Self-esteem moderated the associations between discrimination and positive and negative affect, and stigma consciousness moderated the link with negative affect. Practical implications and directions for future research are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Residential solar photovoltaic (PV) customers are increasingly buying PV systems in online marketplaces, where customers can compare multiple quotes from several installers on quote platforms. In this study, we use data from an online marketplace to explore how quote platform design affects customer experiences. We analyze how four design changes affected customer experiences in terms of factors such as prices. We find that three of the four design changes are associated with statistically significant and robust price reductions, even though none of the changes were implemented specifically to reduce prices. The results suggest that even seemingly small platform design changesmore » can affect PV customer experiences in online marketplaces.« less

2012-11-01

Critical ethnography was used as a pragmatic research methodology to explore the postpartum depression (PPD) experiences of immigrant and refugee women. We examined the social, political, economic, and historical factors that affected the help-seeking behavior of these women during PPD episodes. The critical ethnography method allowed participants to share their experiences with each other and afforded opportunities to the researchers to acknowledge and validate, rather than simply observe and record, their testimony. This study of PPD thus increased our awareness and understanding of the health issues of immigrant and refugee women.

Knowledge of potentially modifiable risk factors for neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD) is important. This study longitudinally explores modifiable vascular risk factors for NPS in AD. Participants enrolled in the Cache County Study on Memory in Aging with no dementia at baseline were subsequently assessed over three additional waves, and those with incident (new onset) dementia were invited to join the Dementia Progression Study for longitudinal follow-up. A total of 327 participants with incident AD were identified and assessed for the following vascular factors: atrial fibrillation, hypertension, diabetes mellitus, angina, coronary artery bypass surgery, myocardial infarction, cerebrovascular accident, and use of antihypertensive or diabetes medicines. A vascular index (VI) was also calculated. NPS were assessed over time using the Neuropsychiatric Inventory (NPI). Affective and Psychotic symptom clusters were assessed separately. The association between vascular factors and change in NPI total score was analyzed using linear mixed model and in symptom clusters using a random effects model. No individual vascular risk factors or the VI significantly predicted change in any individual NPS. The use of antihypertensive medications more than four times per week was associated with higher total NPI and Affective cluster scores. Use of antihypertensive medication was associated with higher total NPI and Affective cluster scores. The results of this study do not otherwise support vascular risk factors as modifiers of longitudinal change in NPS in AD. Copyright © 2013 John Wiley & Sons, Ltd.

South African adolescents with cystic fibrosis: a qualitative exploration of their bio-psychosocial fields.

PubMed

Hugo, Carina Jacobie; van der Merwe, Mariette

2014-01-01

This qualitative case study explored risk factors and protective factors in the bio-psychosocial fields of adolescents living with cystic fibrosis (CF). Semi-structured interviews were conducted with adolescents in the middle and late adolescent years (15-22 years) who had the defining characteristics of CF and were living in Gauteng province. Themes emerged from individual interviews. The fundamental human need to be understood and to understand was negatively affected as the illness affected socialisation and learning. Participants experienced an array of emotions including loss and bereavement linked to their illness and when friends with CF died. Constructive internal dialogue and positive thinking emerged as protective variables. Participants generally showed awareness of how they regulated their contact with the illness and how they self-regulate. Despite the severity of their symptoms and the taxing demands of managing CF, participants expressed hope for the future and could find some meaning in the illness. Adolescents with CF who participated in this study indicated that they felt different from their peers. Apart from the general developmental tasks typical to adolescence they faced the challenge of managing a severe chronic and potentially terminal illness.

2014-01-01

Transfer of patients in medical emergency situations is one of the most important missions of emergency medical service (EMS) staffs. So this study was performed to explore affecting factors in EMS staffs' decision during transporting of patients in medical situations to medical facilities. The participants in this qualitative study consisted of 18 EMS staffs working in prehospital care facilities in Tehran, Iran. Data were gathered through semistructured interviews. The data were analyzed using a content analysis approach. The data analysis revealed the following theme: "degree of perceived risk in EMS staffs and their patients." This theme consisted of two main categories: (1) patient's condition' and (2) the context of the EMS mission'. The patent's condition category emerged from "physical health statuses," "socioeconomic statuses," and "cultural background" subcategories. The context of the EMS mission also emerged from two subcategories of "characteristics of the mission" and EMS staffs characteristics'. EMS system managers can consider adequate technical, informational, financial, educational, and emotional supports to facilitate the decision making of their staffs. Also, development of an effective and user-friendly checklist and scoring system was recommended for quick and easy recognition of patients' needs for transportation in a prehospital situation.

2017-01-01

Exercise classes are a popular form of physical activity. A greater understanding of the individual difference factors that might influence the outcomes of such classes could help to minimize the high dropout rates associated with exercise. The study explored the effects of dominant attentional style and degree of self-determination on affective, cognitive, and behavioral outcomes following structured exercise classes. Data from 417 female participants revealed that those with a dominant attentional style for association (Associators) reported significantly (P < 0.05) more positive affective, cognitive, and behavioral outcomes than did Dissociators, and were more self-determined. Highly self-determined individuals reported the most positive outcomes. Almost 29% of the variance in participants' affective valence could be explained by Dissociators' behavioral regulations. Results lend support to the notion that attentional style is associated with motivation. The combination of attentional style and degree of self-determination appear to be noteworthy individual difference factors that influence responses to exercise classes and could thus have a bearing on long-term exercise adherence. © 2015 John Wiley & Sons A/S.

Fibroblast growth factor receptors in breast cancer.

PubMed

Wang, Shuwei; Ding, Zhongyang

2017-05-01

Fibroblast growth factor receptors are growth factor receptor tyrosine kinases, exerting their roles in embryogenesis, tissue homeostasis, and development of breast cancer. Recent genetic studies have identified some subtypes of fibroblast growth factor receptors as strong genetic loci associated with breast cancer. In this article, we review the recent epidemiological findings and experiment results of fibroblast growth factor receptors in breast cancer. First, we summarized the structure and physiological function of fibroblast growth factor receptors in humans. Then, we discussed the common genetic variations in fibroblast growth factor receptors that affect breast cancer risk. In addition, we also introduced the potential roles of each fibroblast growth factor receptors isoform in breast cancer. Finally, we explored the potential therapeutics targeting fibroblast growth factor receptors for breast cancer. Based on the biological mechanisms of fibroblast growth factor receptors leading to the pathogenesis in breast cancer, targeting fibroblast growth factor receptors may provide new opportunities for breast cancer therapeutic strategies.

Toward healthy migration: an exploratory study on the resilience of migrant domestic workers from the Philippines.

2014-08-01

Domestic workers face many migration-related stressors that affect their mental health. Currently there is an emphasis in the literature on these workers' problems and vulnerability, while there is little insight into factors that positively affect their mental health. In this study, we describe a range of factors that potentially contribute to the resilience of female domestic workers from the Philippines, and explore their relation to stress and well-being. The study used an explorative, mixed-methods design. First, data were collected using questionnaires (n = 500) to assess self-perceived stress levels, well-being, personal resources, and social resources. Then, findings from the questionnaires were validated and elaborated on in a workshop (n = 23) and two focus groups (n = 13; n = 8). Results show that participants perceived their well-being abroad as relatively good, while they also experienced high levels of stress. Workers used a variety of resources in dealing with stress. Socially oriented coping strategies and spirituality seemed to play an important role as personal resources, while the influence of reasons for migration was less clear. Employers and (access to) social networks appeared important in determining social resources. Social resources were more often related to stress and well-being than were personal resources. Findings from this study can help to design strengths-based interventions aimed at improving the well-being of female domestic workers and preventing mental health problems. The environmental factors and structural constraints that provide the context for resilience should be further explored as they influence the ability to mobilize resources. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

How social factors and behavioural strategies affect feeding and social interaction patterns in pigs.

Boumans, Iris J M M; de Boer, Imke J M; Hofstede, Gert Jan; Bokkers, Eddie A M

2018-04-26

Animals living in groups compete for food resources and face food conflicts. These conflicts are affected by social factors (e.g. competition level) and behavioural strategies (e.g. avoidance). This study aimed to deepen our understanding of the complex interactions between social factors and behavioural strategies affecting feeding and social interaction patterns in animals. We focused on group-housed growing pigs, Sus scrofa, which typically face conflicts around the feeder, and of which patterns in various competitive environments (i.e. pig:feeder ratio) have been documented soundly. An agent-based model was developed to explore how interactions among social factors and behavioural strategies can affect various feeding and social interaction patterns differently under competitive situations. Model results show that pig and diet characteristics interact with group size and affect daily feeding patterns (e.g. feed intake and feeding time) and conflicts around the feeder. The level of competition can cause a turning point in feeding and social interaction patterns. Beyond a certain point of competition, meal-based (e.g. meal frequency) and social interaction patterns (e.g. displacements) are determined mainly by behavioural strategies. The average daily feeding time can be used to predict the group size at which this turning point occurs. Under the model's assumptions, social facilitation was relatively unimportant in the causation of behavioural patterns in pigs. To validate our model, simulated patterns were compared with empirical patterns in conventionally housed pigs. Similarities between empirical and model patterns support the model results. Our model can be used as a tool in further research for studying the effects of social factors and group dynamics on individual variation in feeding and social interaction patterns in pigs, as well as in other animal species.

2016-12-15

Association network approaches have recently been proposed as a means for exploring the associations between bacterial communities. In the present study, high-throughput sequencing was employed to investigate the seasonal variations in the composition of bacterioplankton communities in six eutrophic urban lakes of Nanjing City, China. Over 150,000 16S rRNA sequences were derived from 52 water samples, and correlation-based network analyses were conducted. Our results demonstrated that the architecture of the co-occurrence networks varied in different seasons. Cyanobacteria played various roles in the ecological networks during different seasons. Co-occurrence patterns revealed that members of Cyanobacteria shared a very similar niche and they had weak positive correlations with other phyla in summer. To explore the effect of environmental factors on species-species co-occurrence networks and to determine the most influential environmental factors, the original positive network was simplified by module partitioning and by calculating module eigengenes. Module eigengene analysis indicated that temperature only affected some Cyanobacteria; the rest were mainly affected by nitrogen associated factors throughout the year. Cyanobacteria were dominant in summer which may result from strong co-occurrence patterns and suitable living conditions. Overall, this study has improved our understanding of the roles of Cyanobacteria and other bacterioplankton in ecological networks. Copyright © 2016 Elsevier B.V. All rights reserved.

Kalb, M

1983-07-01

Despite soaring divorce rates and the effect of divorce on the individual, family, and society, professional scientific literature examining the factors governing the decision to divorce has been scant. The author suggests that the key variable affecting the decision to divorce can best be understood through an exploration of the individual's conception of the alternative. The factors that comprise the conception of the alternative are discussed and the problems inherent in its valid construction by the patient are examined. The therapeutic implementation of this conception is outlined.

Beyond Inhibition: A Dual-Process Perspective to Renew the Exploration of Binge Drinking

PubMed Central

Lannoy, Séverine; Billieux, Joël; Maurage, Pierre

2014-01-01

Binge drinking is a widespread alcohol-consumption pattern in youth and is linked to cognitive consequences, mostly for executive functions. However, other crucial factors remain less explored in binge drinking and notably the emotional-automatic processes. Dual-process model postulates that addictive disorders are not only due to impaired reflective system (involved in deliberate behaviors), but rather to an imbalance between under-activated reflective system and over-activated affective-automatic one (involved in impulsive behaviors). This proposal has been confirmed in alcohol-dependence, but has not been tested in binge drinking. The observation of comparable impairments in binge drinking and alcohol-dependence led to the “continuum hypothesis,” suggesting similar deficits across different alcohol-related disorders. In this perspective, applying the dual-process model to binge drinking might renew the understanding of this continuum hypothesis. A three-axes research agenda will be proposed, exploring: (1) the affective-automatic system in binge drinking; (2) the systems’ interactions and imbalance in binge drinking; (3) the evolution of this imbalance in the transition between binge drinking and alcohol-dependence.

An exploration of factors affecting the long term psychological impact and deterioration of mental health in flooded households.

Lamond, Jessica Elizabeth; Joseph, Rotimi D; Proverbs, David G

2015-07-01

The long term psychological effect of the distress and trauma caused by the memory of damage and losses associated with flooding of communities remains an under researched impact of flooding. This is particularly important for communities that are likely to be repeatedly flooded where levels of mental health disorder will damage long term resilience to future flooding. There are a variety of factors that affect the prevalence of mental health disorders in the aftermath of flooding including pre-existing mental health, socio-economic factors and flood severity. However previous research has tended to focus on the short term impacts immediately following the flood event and much less focus has been given to the longer terms effects of flooding. Understanding of factors affecting the longer term mental health outcomes for flooded households is critical in order to support communities in improving social resilience. Hence, the aim of this study was to explore the characteristics associated with psychological distress and mental health deterioration over the longer term. The research examined responses from a postal survey of households flooded during the 2007 flood event across England. Descriptive statistics, correlation analysis and binomial logistic regression were applied to data representing household characteristics, flood event characteristics and post-flood stressors and coping strategies. These factors were related to reported measures of stress, anxiety, depression and mental health deterioration. The results showed that household income, depth of flooding; having to move out during reinstatement and mitigating actions are related to the prevalence of psycho-social symptoms in previously flooded households. In particular relocation and household income were the most predictive factors. The practical implication of these findings for recovery after flooding are: to consider the preferences of households in terms of the need to move out during restorative building works and the financial resource constraints that may lead to severe mental hardship. In addition the findings suggest that support with installing mitigation measures may lead to improved mental health outcomes for communities at risk. Copyright © 2015 The Authors.

2016-01-01

There have been a number of crowdsourcing projects to support people with disabilities. However, there is little exploration of what motivates people to participate in such crowdsourcing projects. In this study we investigated how different motivational factors can affect the participation of people in a crowdsourcing project to support visually disabled students. We are developing "DescribeIT", a crowdsourcing project to support blind and partially students by having sighted people describe images in digital learning resources. We investigated participants' behavior of the DescribeIT project using three conditions: one intrinsic motivation condition and two extrinsic motivation conditions. The results showed that participants were significantly intrinsically motivated to participate in the DescribeIT project. In addition, participants' intrinsic motivation dominated the effect of the two extrinsic motivational factors in the extrinsic conditions.

Exploring the Relationship between Negative Urgency and Dysregulated Eating: Etiologic Associations and the Role of Negative Affect

2013-01-01

Negative urgency (i.e., the tendency to engage in rash action in response to negative affect) has emerged as a critical personality trait contributing to individual differences in binge eating. However, studies investigating the extent to which genetic and/or environmental influences underlie the effects of negative urgency on binge eating are lacking. Moreover, it remains unclear whether negative urgency-binge eating associations are simply due to the well-established role of negative affect in the development/maintenance of binge eating. The current study addresses these gaps by examining phenotypic and etiologic associations between negative urgency, negative affect, and dysregulated eating (i.e., binge eating, emotional eating) in a sample of 222 same-sex female twin pairs from the Michigan State Twin Registry. Negative urgency was significantly associated with both dysregulated eating symptoms, even after controlling for the effects of negative affect. Genetic factors accounted for the majority (62–77%) of this phenotypic association, although a significant proportion of this genetic covariation was due to genetic influences in common with negative affect. Non-shared environmental factors accounted for a relatively smaller (23–38%) proportion of the association, but these non-shared environmental effects were independent of negative affect. Findings suggest that the presence of emotion-based rash action, combined with high levels of negative affect, may significantly increase genetic risk for dysregulated eating. PMID:23356217

Purpose To explore primary care providers' HIV prevention practices for older adults. Primary care providers' perceptions and awareness were explored to understand factors that affect their provision of HIV prevention materials and HIV screening for older adults. Design and Method Data were collected through 24 semistructured interviews with primary care providers (i.e., physicians, physician assistants, and nurse practitioners) who see patients older than 50 years. Results Results reveal facilitators and barriers of HIV prevention for older adults among primary care providers and understanding of providers' HIV prevention practices and behaviors. Individual, patient, institutional, and societal factors influenced HIV prevention practices among participants, for example, provider training and work experience, lack of time, discomfort in discussing HIV/AIDS with older adults, stigma, and ageism were contributing factors. Furthermore, factors specific to primary and secondary HIV prevention were identified, for instance, the presence of sexually transmitted infections influenced providers' secondary prevention practices. Implications HIV disease, while preventable, is increasing among older adults. These findings inform future research and interventions aimed at increasing HIV prevention practices in primary care settings for patients older than 50. PMID:25736425

2015-02-05

Armed conflict has been described as an important contributor to the social determinants of health and a driver of health inequity, including maternal health. These conflicts may severely reduce access to maternal health services and, as a consequence, lead to poor maternal health outcomes for a period extending beyond the conflict itself. As such, understanding how maternal health-seeking behaviour and utilisation of maternal health services can be improved in post-conflict societies is of crucial importance. This study aims to explore the determinants (barriers and facilitators) of women's uptake of maternal, sexual and reproductive health services (MSRHS) in two post-conflict settings in sub-Saharan Africa; Burundi and Northern Uganda, and how uptake is affected by exposure to armed conflict. This is a qualitative study that utilised in-depth interviews and focus group discussions (FGDs) for data collection. One hundred and fifteen participants took part in the interviews and FGDs across the two study settings. Participants were women of reproductive age, local health providers and staff of non-governmental organizations. Issues explored included the factors affecting women's utilisation of a range of MSRHS vis-à-vis conflict exposure. The framework method, making use of both inductive and deductive approaches, was used for analyzing the data. A complex and inter-related set of factors affect women's utilisation of MSRHS in post-conflict settings. Exposure to armed conflict affects women's utilisation of these services mainly through impeding women's health seeking behaviour and community perception of health services. The factors identified cut across the individual, socio-cultural, and political and health system spheres, and the main determinants include women's fear of developing pregnancy-related complications, status of women empowerment and support at the household and community levels, removal of user-fees, proximity to the health facility, and attitude of health providers. Improving women's uptake of MSRHS in post-conflict settings requires health system strengthening initiatives that address the barriers across the individual, socio-cultural, and political and health system spheres. While addressing financial barriers to access is crucial, attention should be paid to non-financial barriers as well. The goal should be to develop an equitable and sustainable health system.

In spite of increasing prevalence of diabetes among Kenyans and evidence suggesting Kenyans with diabetes maintain poor glycemic control, no one has examined the role of cultural attitudes, beliefs, and practices in their self-management of diabetes. The purpose of this ethnographic study was to describe diabetes self-management among the Swahili of coastal Kenya, and explore factors that affect diabetes self-management within the context of Swahili culture. Thirty men and women with type 2 diabetes from Lamu town, Kenya, participated in this study. Diabetes self-management was insufficiently practiced, and participants had limited understanding of diabetes. Economic factors such as poverty and the high cost of biomedical care appear to have more influence in self-management behavior than socio-cultural and educational factors do. Economic and socio-cultural influences on diabetes self-management should not be underestimated, especially in a limited resource environment like coastal Kenya, where biomedical care is not accessible or affordable to all.

Positive organizational behavior and safety in the offshore oil industry: Exploring the determinants of positive safety climate.

PubMed

Hystad, Sigurd W; Bartone, Paul T; Eid, Jarle

2014-01-01

Much research has now documented the substantial influence of safety climate on a range of important outcomes in safety critical organizations, but there has been scant attention to the question of what factors might be responsible for positive or negative safety climate. The present paper draws from positive organizational behavior theory to test workplace and individual factors that may affect safety climate. Specifically, we explore the potential influence of authentic leadership style and psychological capital on safety climate and risk outcomes. Across two samples of offshore oil-workers and seafarers working on oil platform supply ships, structural equation modeling yielded results that support a model in which authentic leadership exerts a direct effect on safety climate, as well as an indirect effect via psychological capital. This study shows the importance of leadership qualities as well as psychological factors in shaping a positive work safety climate and lowering the risk of accidents.

Non-deployment factors affecting psychological wellbeing in military personnel: literature review.

PubMed

Brooks, Samantha K; Greenberg, Neil

2018-02-01

Most military mental health research focuses on the impact of deployment-related stress; less is known about how everyday work-related factors affect wellbeing. This systematic narrative literature review aimed to identify non-deployment-related factors contributing to the wellbeing of military personnel. Electronic literature databases were searched and the findings of relevant studies were used to explore non-deployment-related risk and resilience factors. Fifty publications met the inclusion criteria. Determinants of non-deployment stress were identified as: relationships with others (including leadership/supervisory support; social support/cohesion; harassment/discrimination) and role-related stressors (role conflict; commitment and effort-reward imbalance; work overload/job demands; family-related issues/work-life balance; and other factors including control/autonomy, physical work environment and financial strain). Factors positively impacting wellbeing (such as exercise) were also identified. The literature suggests that non-deployment stressors present a significant occupational health hazard in routine military environments and interpersonal relationships at work are of fundamental importance. Findings suggest that in order to protect the wellbeing of personnel and improve performance, military organisations should prioritise strengthening relationships between employees and their supervisors/colleagues. Recommendations for addressing these stressors in British military personnel were developed.

Violent conflict and opiate use in low and middle-income countries: a systematic review.

2014-03-01

Violent conflicts disproportionately affect populations in low and middle-income countries, and exposure to conflict is a known risk factor for mental disorders and substance use, including use of illicit opiates. Opiate use can be particularly problematic in resource-limited settings because few treatment options are available and dependence can impede economic development. In this systematic review, we explore the relationship between violent conflict and opiate use in conflict-affected populations in low and middle-income countries. We searched MEDLINE, PsychINFO, SCOPUS, PILOTS, and select grey literature databases using a defined list of key terms related to conflict and opiate use, screened the results for relevant and methodologically rigorous studies, and conducted a forward search of the bibliographies of selected results to identify additional studies. We screened 707 articles, selecting 6 articles for inclusion: 4 quantitative studies and 2 qualitative studies that examined populations in 9 different countries. All study participants were adults (aged 15-65) living in or displaced from a conflict-affected country. Data sources included death records, hospital records, and interviews with refugees, internally displaced persons, and others affected by conflict. Overall, we found a positive, but ambiguous, association between violent conflict and opiate use, with five of six studies suggesting that opiate use increases with violent conflict. Five key factors mediate the conceptual relationship between opiate use and violent conflict: (1) pre-conflict opiate presence, (2) mental disorders, (3) lack of economic opportunity, (4) changes in social norms or structure, and (5) changes in drug availability. The strength and direction of the association between opiate use and violent conflict and the proposed mediating factors may differ between contexts, necessitating country and population-specific research and interventions. Prevalence of opiate use prior to the start of conflict was common to all populations in which conflict induced a change in opiate use, suggesting that interventions to reduce opiate use and future research should focus on such populations. Population-based, longitudinal studies that use systematic measures of exposure to conflict and opiate use are needed to further explore this association and its mediating factors.

In the current study we explored the role of desire thinking in predicting binge eating independently of Body Mass Index, negative affect and irrational food beliefs. A sample of binge eaters (n=77) and a sample of non-binge eaters (n=185) completed the following self-report instruments: Hospital Anxiety and Depression Scale, Irrational Food Beliefs Scale, Desire Thinking Questionnaire, and Binge Eating Scale. Mann-Whitney U tests revealed that all variable scores were significantly higher for binge eaters than non-binge eaters. A logistic regression analysis indicated that verbal perseveration was a predictor of classification as a binge eater over and above Body Mass Index, negative affect and irrational food beliefs. A hierarchical regression analysis, on the combined sample, indicated that verbal perseveration predicted levels of binge eating independently of Body Mass Index, negative affect and irrational food beliefs. These results highlight the possible role of desire thinking as a risk factor for binge eating. Copyright © 2015 Elsevier Ltd. All rights reserved.

Adolescents' multiple versus single primary attachment figures, reorganization of attachment hierarchy, and adjustments: the important people interview approach.

Using 212 adolescents from a central-European country (mean age = 14.02, SD = 2.05, ranged from 11 to 18 years; females = 54%) and a multi-informant method to measure adolescents' behavioral and emotional adjustments, the present study explored three aspects regarding the attachment hierarchy. (1) The three types of behavioral systems of Rosenthal and Kobak's important people interview (IPI) were initially validated using an exploratory factor analysis with a US sample. Using a confirmatory factor analysis with a Czech sample, we replicated these three behavioral systems: attachment bond, support seeking, and affiliation. (2) We found that adolescents who developed attachment bond to multiple primary attachment figures were likely to score lower on both teacher-rated and parent-rated internalizing problems compared to those who had a single primary attachment figure. These multiple primary attachment figures tended to be family members (not peers). (3) Early adolescents who placed parents low in their attachment hierarchy scored higher on self-reported negative affect and lower on self-reported positive affect compared to early adolescents who placed parents high. The present study highlights multiple (vs. single) primary attachment figures as a protective factor and the premature reorganization of attachment hierarchy as a risk factor for adolescents' emotional and affective adjustments.

Dermatoglyphic anomalies and neurocognitive deficits in sibling pairs discordant for schizophrenia spectrum disorders.

The neurodevelopmental hypothesis of schizophrenia suggests that adverse genetic loading in conjunction with environmental factors early in fetal life causes a disruption of neural development, decades before the symptomatic manifestation of the disease. Neurocognitive deficits have been observed early on the course of schizophrenia, and their association with an early developmental brain lesion has been postulated. Dermatoglyphics have been analyzed in schizophrenia as markers of prenatal brain injury because of their early fetal ontogenesis and susceptibility to the same environmental factors that can also affect cerebral development. The aim of our study was to conduct a comparative examination of neurocognitive functions and dermatoglyphic variables in 89 sibling pairs discordant for schizophrenia spectrum disorders. Therefore, we investigated the association between these two markers to explore the prenatal origin of cognitive deficits in schizophrenia. The affected siblings were significantly impaired on all the cognitive variables assessed (Wisconsin Card Sorting Test, Trail Making Test and Continuous Performance Test) and had a greater number of dermatoglyphic anomalies. These results suggest the influence of intrauterine environmental factors in the siblings affected with schizophrenia. However, we did not detect a significant association between these two vulnerability markers in the schizophrenic patients, suggesting the role of genetic or late environmental factors in the origin of the neurocognitive deficits found in these patients.

To determine the factors that affect patient satisfaction with nurse-led-triage in EDs using a systematic review. Nurses' involvement in the triage services provided in the Emergency Department has been an integral part of practice for several decades in some countries. Although studies exploring patient satisfaction with nurse-led ED triage exist, no systematic review of this evidence is available. MEDLINE, CINAHL, PsycInfo, EMBASE, the Cochrane Library, Joanna Briggs Library and Google Scholar were searched (January 1980-June 2013). Eighteen studies that met the inclusion criteria were reviewed. Factors that affect patient satisfaction with nurse-led-triage include nurses' abilities to provide patient centred care, communication skills, nurses' caring abilities, concern for the patient and competence in diagnosing and treating the health problem. Other factors include availability and visibility of nurses, provision of appropriate health related information in a jargon-free language, nurses' ability to answer questions, and an ability to provide patients with an opportunity to ask questions. There is continued scope for nurse-led-triage services in the ED. Patients are generally satisfied with the service provided by nurses in EDs and report a willingness to see the same professional again in the future if needed. Copyright © 2015 Elsevier Ltd.

Factors affecting midwives' confidence in intrapartum care: a phenomenological study.

midwives are frequently the lead providers of care for women throughout labour and birth. In order to perform their role effectively and provide women with the choices they require midwives need to be confident in their practice. This study explores factors which may affect midwives' confidence in their practice. hermeneutic phenomenology formed the theoretical basis for the study. Prospective longitudinal data collection was completed using diaries and semi-structured interviews. Twelve midwives providing intrapartum care in a variety of settings were recruited to ensure a variety of experiences in different contexts were captured. the principal factor affecting workplace confidence, both positively and negatively, was the influence of colleagues. Perceived autonomy and a sense of familiarity could also enhance confidence. However, conflict in the workplace was a critical factor in reducing midwives' confidence. Confidence was an important, but fragile, phenomenon to midwives and they used a variety of coping strategies, emotional intelligence and presentation management to maintain it. this is the first study to highlight both the factors influencing midwives' workplace confidence and the strategies midwives employed to maintain their confidence. Confidence is important in maintaining well-being and workplace culture may play a role in explaining the current low morale within the midwifery workforce. This may have implications for women's choices and care. Support, effective leadership and education may help midwives develop and sustain a positive sense of confidence.

Complex phenomena in social and financial systems : from bird population growth to the dynamics of the mutual fund industry

Schwarzkopf, Yonathan

2011-12-01

This dissertation explores the impact of gasoline prices and transportation policies on consumer behavior through three separate channels: (1) by affecting the relative operating costs of the vehicles in a household's garage, (2) through stimulation of vehicle purchases due to the Cash-for-Clunkers policy, and (3) due to the availability and accessibility of high quality public transportation. Each of these channels is explored in a separate chapter. The first chapter presents a discrete-continuous household vehicle bundle model, where the household's choice of vehicles and vehicle miles traveled (VMT) is affected by gasoline prices and household and vehicle characteristics. I employ a revealed preference approach that allows for an unlimited choice set, within household vehicle substitution, vehicle specific fixed effects, and unobserved consumer heterogeneity. I use detailed micro-data from the National Household Transportation Survey (NHTS) 2001 and 2009 to explore how different research assumptions affect how elastic households appear to the researcher. The second chapter analyzes the impact of the Cash-for-Clunkers policy implemented in fall 2009 on vehicle demand, overall emissions, gasoline demand, and job creation. We employ a difference-in-difference estimation technique, using Canada as the control group, and find that the policy overpriced the reduction of emissions relative to other emissions reductions policies. Finally, the third chapter explores how the availability of public transportation affects how sensitive individuals are to gasoline prices. Through the use of regressions and the NHTS 2001 dataset, we find that living in a city with good public transportation allows individuals to substitute a portion of their VMT, specifically in commuting, from private to public transit options, thus increasing their sensitivity to gasoline prices. We find that a gasoline tax in conjunction with an improvement in public transportation infrastructure could significantly reduce gasoline demand more than just a gasoline tax alone. There are many factors that affect gasoline and vehicle demand- public policies, household heterogeneity, public transportation availability, and prices. This dissertation explores how different research assumptions and techniques can change how responsive individuals appear to gasoline prices, and analyzes the impact of different transportation policies on overall gasoline and vehicle demand.

Implicit attitudes toward smoking: how the smell of cigarettes influences responses of college-age smokers and nonsmokers.

PubMed

Glock, Sabine; Kovacs, Carrie; Unz, Dagmar

2014-05-01

The habit of smoking may have automatic behavioral components guided by implicit attitudes. Smokers' attitudes toward smoking should thus be less negative than nonsmokers', so that a salient smoking cue (smell) is able to activate positive aspects of these attitudes. An affective priming task was used to explore this hypothesis. Unexpectedly, smokers and nonsmokers showed equally negative implicit attitudes, irrespective of smell. Smokers exposed to the cigarette smell did, however, display generally slower responses than nonsmokers, suggesting attentional bias. This could have implications for smoking policies in contexts where attentional factors affect performance.

There is increasing interest from a social learning perspective in understanding the role of parental factors on adult health behaviors and health outcomes. Our review revealed no studies, to date, that have evaluated the effects of parental substance abuse on reports of chronic pain and coping in adult patients with sickle cell disease (SCD). We explored the effects of parental substance (alcohol or drug) abuse on reports of the sensory, affective and summary indices of pain in 67 adult patients, mean age 38.9 (13.5), with SCD. We also explored the effects of parental substance abuse on psychopathology associated with pain and active coping. Twenty-four percent of patients reported that their parent(s) abused substances. Patients whose parent(s) were characterized as substance abusers reported greater sensory (p=0.02), affective (p=0.01) and summary (VAS; p=0.02) indices of pain as compared to their counterparts, whose parent(s) were not characterized as substance abusers. Patients did not differ in average age, education or the propensity to respond in a socially acceptable manner. There was a significant trend towards patients who characterized their parents as abusers scoring higher than their counterparts on active coping. We propose a Social Learning Theory to explain the current findings and suggest a need for additional prospective research to simultaneously explore biological (genetic) and social factors that influence the interpretation, experience and reporting of chronic pain in adult patients with chronic disease.

Can you un-ring the bell? A qualitative study of how affect influences cancer screening decisions.

The belief that early detection is the best protection against cancer underlies cancer screening. Emerging research now suggests harms associated with early detection may sometimes outweigh the benefits. Governments, cancer agencies, and organizations that publish screening guidelines have found it is difficult to "un-ring the bell" on the message that "early detection is your best protection" because of its widespread communication and enduring resonance. This study explores affective factors-and their interplay with relevant analytical factors-in public/laypersons' decision making about cancer screening. A total of 93 people (47 men, 46 women) attended focus groups about, respectively, prostate cancer screening and breast cancer screening in two Canadian cities. Affective factors were a major influence on many focus group participants' decision making about cancer screening, including fear of cancer and a generalized enthusiasm for prevention/screening, and they were often inspired by anecdotes about the cancer experiences of family and friends. Affect also existed alongside more analytical factors including assessments of reduced risk in the management of any cancer diagnosis if caught early, and, for men, the belief that an unreliable test is "better than nothing," and that men deserve prostate cancer screening because women have breast and cervical cancer screening. Affective factors were particularly noticeable in the sub-groups most supportive of screening and the "early detection" message: older women who felt that mammogram screening should begin at age 40 rather than 50, and older men who felt that prostate cancer screening should be expanded beyond its current unorganized, opportunistic usage. In contrast, younger participants displayed less affective attachments to "early detection" messages and had greater concerns about harms of screening and were more receptive to nuanced messages informed by evidence. Policymakers attempting to communicate more nuanced versions of the "early detection" message need to understand the role of affect alongside other judgments brought into laypersons' decision making processes and anticipate how affective responses to their messages will be shaped, transformed, and potentially subverted by external forces beyond their control. Particularly overt external factors are campaigns by cancer advocacy organizations actively promoting breast and prostate cancer awareness and screening to younger women and men using affectively-charged messages.

Factors impacting the illness trajectory of post-infectious fatigue syndrome: a qualitative study of adults' experiences.

Stormorken, Eva; Jason, Leonard A; Kirkevold, Marit

2017-12-13

Post-infectious fatigue syndrome (PIFS), also known as post-viral fatigue syndrome, is a complex condition resulting in physical, cognitive, emotional, neurological, vocational and/or role performance disabilities in varying degrees that changes over time. The needs for health care resources are high, and costly, as is the economic burden on the affected individuals. Many factors may impact the trajectory, and frequently PIFS develops into a chronic condition. Health professionals lack understanding and knowledge, which results in delayed diagnosis, lack of recognition, appropriate treatment, support and practical help. The aim of our study was to explore, from the perspective of persons who had lived with PIFS for four years following an outbreak of Giardia l. induced enteritis, factors that may have impacted their illness trajectory and how these factors had played a role during different phases. In this retrospective exploratory qualitative study a group of 26 affected adults between 26 and 59 years old were selected for in-depth interviews. A maximum variation sample was recruited from a physician-diagnosed cohort of persons with PIFS enrolled at a tertiary outpatient fatigue clinic. The interviews were audio-recorded, transcribed verbatim and subjected to qualitative content analysis. Unhelpful and helpful factors were associated with the healthcare system, health professionals and the affected persons were experienced as having an impact on the trajectory. External impacting factors which are related to the health care system, providers and the social security system are misdiagnosis, trivialization of symptoms, unhelpful advice, delayed diagnosis and lack of appropriate help. Internal impacting factors related to the affected individuals were lack of knowledge, overestimating functional capacity, assuming the condition will pass, ignoring body signals and denial. A model of impacting factors in each phase of the trajectory is presented. Unmet needs may result in unnecessary disability and high societal and personal costs. Enhanced knowledge of impacting factors in each phase of the trajectory may contribute to more timely and tailored health care services and less use of health services. Increased functional capacity, improved health and ability to work or study may reduce the societal costs and the economic burden for the affected individuals.

The crucial role of the micro caregiving environment: Factors associated with attachment styles in alternative care in Chile.

2017-08-01

The distribution of attachment styles has been shown to differ between groups of children living with their parents and children placed in alternative care (AC), defined as residential or foster. However, this is the first study in Latin America to explore possible factors affecting the quality of attachment in children living in both residential and foster care. Two groups of children (N=57) were compared: one group living in Residential Homes (RC) and the other in Foster Care (FC) in Chile. Children's, caregivers' and structural factors (e.g., child: caregiver ratios) and their links with attachment styles were investigated. The micro caregiving environment (i.e., the specific individual child caregiver relationship), especially the caregivers' engagement, sensitivity, disciplinary control and affection, as well as some structural factors (i.e., child: caregiver ratios), were linked to attachment security in children. Specifically, better emotional caregiving and lower child-caregiver ratios were associated with higher rates of secure attachment. The association between quality of care (as measured by the HOME inventory) and attachment styles seems to be influenced by caregiver relationships (as measured by CCSERSS). Caregiver relationship factors (i.e., affection, engagement and sensitivity) directly impact the quality of the attachment children establish with them while living in AC. However, the relationships that caregivers establish with children under their care can be facilitated by good quality structural factors, particularly child-caregiver ratios.

2009-08-01

Logistic regression, supported by other statistical analyses was used to explore the possible association of risk factors with the fluoroquinolone (FQ)-resistance status of 108 pig finisher farms in Great Britain. The farms were classified as 'affected' or 'not affected' by FQ-resistant E. coli or Campylobacter spp. on the basis of isolation of organisms from faecal samples on media containing 1 mg/l FQ. The use of FQ was the most important factor associated with finding resistant E. coli and/or Campylobacter, which were found on 79% (FQ-resistant E. coli) and 86% (FQ-resistant Campylobacter) of farms with a history of FQ use. However, resistant bacteria were also found on 19% (FQ-resistant E. coli) and 54% (FQ-resistant Campylobacter) of farms with no history of FQ use. For FQ-resistant E. coli, biosecurity measures may be protective and there was strong seasonal variation, with more farms found affected when sampled in the summer. For FQ-resistant Campylobacter, the buying-in of grower stock may increase risk and good on-farm hygiene may be protective. The findings suggest that resistant organisms, particularly Campylobacter, may spread between pig farms.

Documentation Status as a Contextual Determinant of HIV Risk Among Young Transgender Latinas.

The purpose of this study was to explore the contextual factors that determine or mitigate vulnerability to HIV among Latina transgender women. Documentation status (legal authorization to live in the United States) has been cited by other studies as a barrier to recruitment or engagement in HIV-related care among immigrant Latinos, but not explored as a determinant of HIV risk for transgender immigrant Latinas. We collaborated with a community-based organization to explore these contextual, including social and structural, factors. In-depth interviews in Spanish captured life histories of eight 18- to 29-year-old transgender Latinas, who collectively self-identify as chicas trans. Codes were assigned deductively from the interview guide, and emerging themes were identified throughout data collection. Most participants migrated to the United States from Central America after experiencing discrimination and violence in their countries of origin. Participants emphasized documentation status as a critical factor in three areas related to social and structural determinants of HIV risk: gender identity expression, access to services, and relationship power dynamics. Chicas trans who gained legal asylum reported greater control over sexual relationships, improved access to services, and less risky employment. Documentation status emerged as a key HIV risk factor for this population. For undocumented transgender Latinas, legal asylum appears to be a promising HIV-related protective factor. Further research could assess whether legal assistance combined with wraparound support services affects HIV prevention for this population.

New policies in China have recently led to the implementation of clinical pharmacy services in hospitals. We explored the views of hospital administrators, pharmacy directors, clinical pharmacists, and dispensing pharmacists about the factors affecting clinical pharmacy services in China, using the framework approach and organizational theory. We conducted 30 interviews with 130 participants at 29 hospitals (both secondary and tertiary) in Beijing, Zhengzhou, Luoyang, and Shanghai. We found that the barriers to and facilitators of implementation of clinical pharmacy services slotted into the environment and participant dimensions of Scott's adapted version of Leavitt's organizational model. External support from government was perceived as crucial to promoting pharmacy services. It is proposed that the internationally recognized Basel Statements of the International Pharmaceutical Federation also provide a strong foundation for guiding China in implementing clinical pharmacy services.

Cow milk induced allergies (CMA) and asthma in new born.

2016-01-01

The prevalence of asthma and allergic diseases in childhood has increased in several industrialized countries since the second half of the twentieth century. In some countries, the prevalence is still rising, although in others it seems to have plateaued or even decreased. It has been suggested that environmental factors operating prenatally and in early life affect the development of asthma and allergic diseases. Particularly changes in microbial exposure are proposed to play an important role in the development and maturation of the immune system. Thus, the factors that affect microbial exposure, such as mode of delivery and the use of antibiotics, may influence the development of asthma and allergic diseases. Several studies have explored the associations between perinatal factors and children's use of antibiotics and the risk of asthma, with inconsistent findings. The present review article will be focused on the important findings related with factors responsible for above allergic reactions along with asthma in young infants. Also, the influence of cow milk intake will also be taken in account to cover the aspect of cow milk induced allergies and asthma in infants.

2016-01-01

Pre-exposure prophylaxis (PrEP) is effective for preventing HIV among HIV serodiscordant heterosexual couples. Gender roles may influence perceived personal and social risks related to HIV prevention behaviors and may affect use of PrEP. In this study, interviews and focus groups were conducted with 68 individuals from 34 mutually disclosed serodiscordant heterosexual partnerships in Thika, Kenya. Socio-cultural factors that affect adherence to PrEP were explored using grounded analysis. Three factors were identified, which shape perceptions of PrEP: gendered power dynamics and control over decision-making in the household; conflicts between risk reduction strategies and male sexual desire; culture bound definitions of women’s work. Adherence to PrEP in the Partners PrEP Study was high; however, participants articulated conflicting interests related to PrEP in connection with traditional gender roles. The successful delivery of PrEP will require understanding of key social factors, particularly related to gender and dyadic dynamics around HIV serostatus. PMID:26754017

Sample selection, preparation methods, and the apparent tensile properties of silkworm (B. mori) cocoon silk.

2012-06-01

Reported literature values of the tensile properties of natural silk cover a wide range. While much of this inconsistency is the result of variability that is intrinsic to silk, some is also a consequence of differences in the way that silk is prepared for tensile tests. Here we explore how measured mechanical properties of Bombyx mori cocoon silk are affected by two intrinsic factors (the location from which the silk is collected within the cocoon, and the color of the silk), and two extrinsic factors (the storage conditions prior to testing, and different styles of reeling the fiber). We find that extrinsic and therefore controllable factors can affect the properties more than the intrinsic ones studied. Our results suggest that enhanced inter-laboratory collaborations, that lead to standardized sample collection, handling, and storage protocols prior to mechanical testing, would help to decrease unnecessary (and complicating) variation in reported tensile properties.

This study explores the factors affecting the willingness of dialysis patients' family members to become involved in living and deceased organ donation. We utilize cross sectional data on 350 family members of dialysis patients collected through self-administered survey from June to October 2013. The factors affecting willingness to become deceased and living organ donors among respondents were identified by running logistic regressions. The findings reveal that ethnicity, education and role in family are significant factors explaining will­ingness for living donation, while ethnicity, knowledge of organ donation and donor age drive willingness for deceased donation. We also find that the reasons of respondents being unwilling to donate center on the lack of information and family objections for deceased donation, while being medically unfit, scared of surgery and family objections are the reasons for unwillingness to donate living organs. In light of our findings, educational efforts are suggested to decrease the reluctance to become in­volved in living and deceased donation.

Introduction The use of complementary and alternative medicine (CAM) as a source of cure has gained much spectrum worldwide, despite skeptics and advocates of evidence-based practice conceptualized such therapies as human nostrum. Objective This study aimed to explore the factors affecting CAM use among rural communities in Malaysia. Methods A cross-sectional study was carried out on 288 occupants across four rural villages within the District of Selama, Perak, Malaysia. A survey that consisted of socio-economic characteristics, history of CAM use and the validated Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) were used. Results The prevalence of self-reported CAM use over the past one year was 53.1%. Multiple logistic regression analyses yielded three significant predictors of CAM use: monthly household income of less than MYR 2500, higher education level, and positive attitude towards CAM. Conclusion Psycho-socioeconomic factors were significantly associated with CAM use among rural communities in Malaysia. PMID:25375256

Taking into Account the Quality of the Relationship in HIV Disclosure.

Despite growing interest in HIV disclosure, most theoretical frameworks and empirical studies focus on individual and social factors affecting the process, leaving the contribution of interpersonal factors relatively unexplored. HIV transmission and disclosure often occur within a couple however, and this is where disclosure has the most scope as a HIV transmission intervention. With this in mind, this study explores whether perceived relationship quality influences HIV disclosure outcomes. Ninety-five UK individuals with HIV participated in a cross-sectional survey. Retrospective data were collected on their perceived relationship quality prior to disclosing their HIV positive status, and on disclosure outcomes. Perceived relationship quality was found to significantly affect disclosure outcomes. Positive qualities in the relationship were associated with positive outcomes, whereas negative qualities were associated with negative outcomes. Results further confirmed that this association was not merely correlational, but demonstrated predictive power. Relationship quality might act as either a risk or a resilience factor in the disclosure process, and thus warrants greater attention in future research.

Use of electronic medical records (EMR) has the potential to offer quality and safety benefits, but without the adoption of the technology, the benefits will not be realized. This study aimed to identify the factors perceived as relevant by private physicians when considering EMR adoption. A qualitative pre-implementation study was conducted using semi-structured, face to face interviews to explore the perspectives of physicians (n=16) operating in private clinics on the factors affecting their adoption of EMR. A multilevel, work system approach and the immersion/crystallization data analysis technique guided the researchers in examining the data, identifying patterns and key themes, and extracting representative quotes to illustrate these themes. The major factors associated with EMR adoption, which relate to the five categories of a work system, were system usefulness; user interface design; technical support; cost; system reliability; the privacy, confidentiality, and security of patient information; physical space in the clinic; data migration process; adverse work-related factors; and the computer and systems skills of physicians. Pre-implementation identification of factors important to adoption can allow system developers to focus proactively on these factors when developing the system and its implementation strategies, to maximize the likelihood of successful introduction.

A Review of Factors Influencing Athletes' Food Choices.

PubMed

Birkenhead, Karen L; Slater, Gary

2015-11-01

Athletes make food choices on a daily basis that can affect both health and performance. A well planned nutrition strategy that includes the careful timing and selection of appropriate foods and fluids helps to maximize training adaptations and, thus, should be an integral part of the athlete's training programme. Factors that motivate food selection include taste, convenience, nutrition knowledge and beliefs. Food choice is also influenced by physiological, social, psychological and economic factors and varies both within and between individuals and populations. This review highlights the multidimensional nature of food choice and the depth of previous research investigating eating behaviours. Despite numerous studies with general populations, little exploration has been carried out with athletes, yet the energy demands of sport typically require individuals to make more frequent and/or appropriate food choices. While factors that are important to general populations also apply to athletes, it seems likely, given the competitive demands of sport, that performance would be an important factor influencing food choice. It is unclear if athletes place the same degree of importance on these factors or how food choice is influenced by involvement in sport. There is a clear need for further research exploring the food choice motives of athletes, preferably in conjunction with research investigating dietary intake to establish if intent translates into practice.

Perceived difficulty in the theory of planned behaviour: perceived behavioural control or affective attitude?

PubMed

Kraft, Pål; Rise, Jostein; Sutton, Stephen; Røysamb, Espen

2005-09-01

A study was conducted to explore (a) the dimensional structure of perceived behavioural control (PBC), (b) the conceptual basis of perceived difficulty items, and (c) how PBC components and instrumental and affective attitudes, respectively, relate to intention and behaviour. The material stemmed from a two-wave study of Norwegian graduate students (N = 227 for the prediction of intention and N = 110 for the prediction of behaviour). Data were analysed using confirmatory factor analysis (CFA) and multiple regression by the application of structural equation modelling (SEM). CFA suggested that PBC could be conceived of as consisting of three separate but interrelated factors (perceived control, perceived confidence and perceived difficulty), or as two separate but interrelated factors representing self-efficacy (measured by perceived difficulty and perceived confidence or by just perceived confidence) and perceived control. However, the perceived difficulty items also overlapped substantially with affective attitude. Perceived confidence was a strong predictor of exercise intention but not of recycling intention. Perceived control, however, was a strong predictor of recycling intention but not exercise intention. Affective attitudes but not instrumental attitudes were identified as substantial predictors of intentions. The findings suggest that at least under some circumstances it may be inadequate to measure PBC by means of perceived difficulty. One possible consequence may be that the role of PBC as a predictor of intention is somewhat overestimated, whereas the role of (affective) attitude may be similarly underestimated.

Traditional accident analysis typically explores non-time-varying (stationary) factors that affect accident occurrence on roadway segments. However, the impact of time-varying (dynamic) factors is not thoroughly investigated. This paper seeks to simultaneously identify pre-crash stationary and dynamic factors of accident occurrence, while accounting for unobserved heterogeneity. Using highly disaggregate information for the potential dynamic factors, and aggregate data for the traditional stationary elements, a dynamic binary random parameters (mixed) logit framework is employed. With this approach, the dynamic nature of weather-related, and driving- and pavement-condition information is jointly investigated with traditional roadway geometric and traffic characteristics. To additionally account for the combined effect of the dynamic and stationary factors on the accident occurrence, the developed random parameters logit framework allows for possible correlations among the random parameters. The analysis is based on crash and non-crash observations between 2011 and 2013, drawn from urban and rural highway segments in the state of Washington. The findings show that the proposed methodological framework can account for both stationary and dynamic factors affecting accident occurrence probabilities, for panel effects, for unobserved heterogeneity through the use of random parameters, and for possible correlation among the latter. The comparative evaluation among the correlated grouped random parameters, the uncorrelated random parameters logit models, and their fixed parameters logit counterpart, demonstrate the potential of the random parameters modeling, in general, and the benefits of the correlated grouped random parameters approach, specifically, in terms of statistical fit and explanatory power.

In-situ microscale thermomechanical strain measurements have been performed in combination with synchrotron x-ray microdiffraction to understand the fundamental cause of failures in microelectronics devices with through-silicon vias. The physics behind the raster scan and data analysis of the measured strain distribution maps is explored utilizing the energies of indexed reflections from the measured data and applying them for beam intensity analysis and effective penetration depth determination. Moreover, a statistical analysis is performed for the beam intensity and strain distributions along the beam penetration path to account for the factors affecting peak search and strain refinement procedure.

Injuries or conditions that affect appearance can increase adolescents' risk of psychosocial and interpersonal difficulties and may also impact on romantic relationships - an important aspect of adolescent development. A mixed method online approach explored the romantic experiences of 40 adolescents with a variety of visible differences. Young people identified appearance-related romantic concerns that cause distress, and impede the development and enjoyment of romantic relations. In contrast, some shared positive experiences and evidence of attitudes and behaviours that appear to protect against these concerns. Adolescents requested online peer support specific to their appearance-related needs. These findings can inform intervention development.

Falls and fear of falling can affect independence and quality of life of older adults. Falls prevention programs may help avoiding these issues if completed. Understanding factors that are associated with completion of falls prevention programs is important. To reduce fear of falling and increase activity levels, a Matter of Balance (MOB) and un Asunto de Equilibrio (ADE) workshops were offered to 3420 older adults in South Florida between 1 October 2008 and 31 December 2011. Workshops were conducted in English or Spanish over eight, 2-hour sessions. Participants completed a demographic and a pre-post questionnaire. Factors associated with program completion were identified using logistic regression. For MOB, females were more likely to complete the program (OR = 2.076, P = 0.02). For ADE, females, moderate and extreme interference by falls in social activities were found to affect completion (OR = 2.116, P = 0.001; OR = 2.269, P = 0.003 and OR = 4.133, P = 0.008, respectively). Different factors predicted completion of both programs. Awareness of these factors can help lower the attrition rates, increase benefits and cost effectiveness of program. Future research needs to explore why certain groups had a higher likelihood of completing either program.

Hierarchical frameworks are useful constructs when exploring landscape- and local-scale factors affecting patterns of vegetation in riparian areas. In drylands, which have steep environmental gradients and high habitat heterogeneity, landscape-scale variables, such as climate, can change rapidly along a river's course, affecting the relative influence of environmental variables at different scales. To assess how landscape-scale factors change the structure of riparian vegetation, we measured riparian vegetation composition along the Colorado River through Grand Canyon, determined which factors best explain observed changes, identified how richness and functional diversity vary, and described the implications of our results for river management. Cluster analysis identified three divergent floristic groups that are distributed longitudinally along the river. These groups were distributed along gradients of elevation, temperature and seasonal precipitation, but were not associated with annual precipitation or local-scale factors. Species richness and functional diversity decreased as a function of distance downstream showing that changing landscape-scale factors result in changes to ecosystem characteristics. Species composition and distribution remain closely linked to seasonal precipitation and temperature. These patterns in floristic composition in a semiarid system inform management and provide insights into potential future changes as a result of shifts in climate and changes in flow management.

To undertake a review of peer-reviewed literature to explore factors affecting pharmacists' performance. The following databases were searched: Medline, Embase, Scopus, ISI Web of Knowledge and PsychInfo. Inclusion criteria were: English language only, published between 1990 and 2010 and published in the United Kingdom (UK), United States of America (USA), Canada, Australia, New Zealand or Europe. The search strategy identified 37 items. The review found that there was some evidence to suggest that pharmacists with certain characteristics (e.g. being male, being of ethnic minority origin, working in community pharmacy and having trained overseas) were more likely to experience performance problems. Factors relating to workload and work environment were associated with performance problems, particularly in relation to errors. There was some limited evidence to suggest that experiencing problems with alcohol or drugs could negatively impact on pharmacists' performance. The findings suggest that pharmacist performance may be affected by multiple factors, including personal characteristics such as age, gender, ethnicity, place of primary qualification, factors associated with the workplace and mental and physical health problems. The evidence is not unequivocal and gaps in the literature exist, suggesting that pharmacist performance is an under-researched area. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Hispanics are disproportionately affected by substance abuse, intimate partner violence, and HIV. Although the relationship between these conditions has been documented in the literature, few studies have explored the intersection of these health problems and their culture-related risk factors in an integrative manner. The purpose of this study is to explore the experiences that Hispanic heterosexual males in South Florida have with substance abuse, violence, and risky sexual behaviors. Three focus groups with a total of 25 Hispanic adult men are completed and analyzed using grounded theory. Three core categories emerge from the data. These include la cuna de problemas sociales (the cradle of social problems), ramas de una sola mata (branches from one same tree), and la mancha negra (the black stain). This study suggests that substance abuse, violence, and risky sexual behaviors are linked conditions with common cultural and socioenvironmental risk factors and consequences. PMID:19915207

The purpose of our study was to explore the experiences of marriage and family therapists in working with violent couples. In particular, we focused on therapists’ questions and feelings of competency pertaining to violence assessment and treatment, the difficulties they face during their practices, and the factors that affect their practice. Data for this study was collected via a focus group that lasted approximately an hour. The participants included five marriage and family therapists. A set of questions were used to explore experiences of therapists who were working with clients who are experiencing domestic violence. The research team recorded the answers to these questions as well as associated discussion. A grounded theory approach was used to analyze the data. Six themes were derived from the coded data: acknowledgment and reliance on systemic foundations, therapist factors, assessment, treatment considerations, sex of batterers, and training in Marriage and Family Therapy programs.

Teachers play a key role in moving reform-based science education practices into the classroom. Based on research that emphasizes the importance of teachers' affective states, this study aimed to explore the constructs pedagogical discontentment, science teaching self-efficacy, intentions to reform, and their correlations. Also, it aimed to provide empirical evidence in light of a previously proposed theoretical model while focusing on an entirely new context in Middle East. Data were collected in Saudi Arabia with a total of randomly selected 994 science teachers, 656 of whom were females and 338 were males. To collect the data, the Arabic versions of the Science Teachers' Pedagogical Discontentment scale, the Science Teaching Efficacy Beliefs Instrument and the Intentions to Reform Science Teaching scale were developed. For assuring the validity of the instruments in a non-Western context, rigorous cross-cultural validations procedures were followed. Factor analyses were conducted for construct validation and descriptive statistical analyses were performed including frequency distributions and normality checks. Univariate analyses of variance were run to explore statistically significant differences between groups of teachers. Cross-tabulation and correlation analyses were conducted to explore relationships. The findings suggest effect of teacher characteristics such as age and professional development program attendance on the affective states. The results demonstrate that teachers who attended a relatively higher number of programs had lower level of intentions to reform raising issues regarding the conduct and outcomes of professional development. Some of the findings concerning interrelationships among the three constructs challenge and serve to expand the previously proposed theoretical model.

Using constructs from the Theory of Planned Behavior and theories of altruism, this article explores how multiple motivations and beliefs for blood donation are clustered and change across the donor career. In so doing important distinctions, for blood donation, between impure altruism, pure altruism, and warm glow are explored. Measures of intentions, cognitive and affective attitudes, role merger, pure altruism, trust, self-efficacy, subjective and moral norms, and habit formation were assessed in a sample of 12,580 whole blood donors. Analyses showed that a distinction between first-time, novice (one to four donations), and experienced donors (five or more donations) is justified. Principal components analysis and confirmatory factor analytic Multiple-Indicator Multiple-Causal models were used to compare models across these groups. A cognition-behavior (CB) factor, including intentions, was common to all groups. First-time and novice donors were marked by a newly identified motivational factor: "reluctant altruism" (i.e., the motivation to donate because of a lack of trust in others). First-time donors exhibited an impure altruism factor whereas for experienced donors warm glow and pure altruism factors were observed. For first-time donors impure altruism and reluctant altruism were both associated with the CB factor in females and impure altruism only in males. For both sexes reluctant altruism was associated of the CB factor in novice donors and warm glow and pure altruism for experienced donors. New avenues for intervention are suggested by the emergence of reluctant altruism for novice donors and warm glow for experienced donors. The importance of distinguishing aspects of altruism is highlighted. © 2012 American Association of Blood Banks.

There is growing interest in validating tools aimed at supporting the clinical decision-making process and research. However, an increased bureaucratization of clinical practice and redundancies in the measures collected have been reported by clinicians. Redundancies in clinical assessments affect negatively both patients and nurses. To validate a meta-tool measuring the risks/problems currently estimated by multiple tools used in daily practice. A secondary analysis of a database was performed, using a cross-validation and a longitudinal study designs. In total, 1464 patients admitted to 12 medical units in 2012 were assessed at admission with the Brass, Barthel, Conley and Braden tools. Pertinent outcomes such as the occurrence of post-discharge need for resources and functional decline at discharge, as well as falls and pressure sores, were measured. Explorative factor analysis of each tool, inter-tool correlations and a conceptual evaluation of the redundant/similar items across tools were performed. Therefore, the validation of the meta-tool was performed through explorative factor analysis, confirmatory factor analysis and the structural equation model to establish the ability of the meta-tool to predict the outcomes estimated by the original tools. High correlations between the tools have emerged (from r 0.428 to 0.867) with a common variance from 18.3% to 75.1%. Through a conceptual evaluation and explorative factor analysis, the items were reduced from 42 to 20, and the three factors that emerged were confirmed by confirmatory factor analysis. According to the structural equation model results, two out of three emerged factors predicted the outcomes. From the initial 42 items, the meta-tool is composed of 20 items capable of predicting the outcomes as with the original tools. © 2016 John Wiley & Sons, Ltd.

Several randomized controlled trials (RCTs) and meta-analyses support the benefits of flavanols on cardiometabolic health, but the factors affecting variability in the responses to these compounds have not been properly assessed. The objectives of this meta-analysis were to systematically collect the RCTs-based-evidence of the effects of flavanol-containing tea, cocoa and apple products on selected biomarkers of cardiometabolic risk and to explore the influence of various factors on the variability in the responses to the consumption of these products. A total of 120 RCTs were selected. Despite a high heterogeneity, the intake of the flavanol-containing products was associated using a random model with changes (reported as standardized difference in means (SDM)) in body mass index (−0.15, p < 0.001), waist circumference (−0.29, p < 0.001), total-cholesterol (−0.21, p < 0.001), LDL-cholesterol (−0.23, p < 0.001), and triacylglycerides (−0.11, p = 0.027), and with an increase of HDL-cholesterol (0.15, p = 0.005). Through subgroup analyses, we showed the influence of baseline-BMI, sex, source/form of administration, medication and country of investigation on some of the outcome measures and suggest that flavanols may be more effective in specific subgroups such as those with a BMI ≥ 25.0 kg/m2, non-medicated individuals or by specifically using tea products. This meta-analysis provides the first robust evidence of the effects induced by the consumption of flavanol-containing tea, cocoa and apple products on weight and lipid biomarkers and shows the influence of various factors that can affect their bioefficacy in humans. Of note, some of these effects are quantitatively comparable to those produced by drugs, life-style changes or other natural products. Further, RCTs in well-characterized populations are required to fully comprehend the factors affecting inter-individual responses to flavanol and thereby improve flavanols efficacy in the prevention of cardiometabolic disorders.

Safety climate survey was sent to 642 plants in 2003 to explore safety climate practices in the Korean manufacturing plants, especially in hazardous chemical treating plants. Out of 642 plants contacted 195 (30.4%) participated in the surveys. Data were collected by e-mail using SQL-server and mail. The main objective of this study was to explore safety climate practices (level of safety climate and the underlying problems). In addition, the variables that may influence the level of safety climate among managers and workers were explored. The questionnaires developed by health and safety executive (HSE) in the UK were modified to incorporate differences in Korean culture. Eleven important factors were summarized. Internal reliability of these factors was validated. Number of employees in the company varied from less than 30 employees (9.2%) to over 1000 employees (37.4%). Both managers and workers showed generally high level of safety climate awareness. The major underlying problems identified were inadequate health and safety procedures/rules, pressure for production, and rule breaking. The length of employment was a significant contributing factor to the level of safety climate. In this study, participants showed generally high level of safety climate, and length of employment affected the differences in the level of safety climate. Managers' commitment to comply safety rules, procedures, and effective safety education and training are recommended.

We run Exploratory and Confirmatory Factor Analyses of the Minnesota Nicotine Withdrawal Scale (MNWS) and of the MNWS-Revised (MNWS-R). Psychometric properties were also explored. Adult Italian smokers, 366 in all, were assessed via the MNWS-R together with rating scales measuring cigarette dependence, alcohol use, anxiety sensitivity and negative affect at baseline and after 3 months. The MNWS showed good psychometric properties (α = 0.85; rtt = 0.59) and a unidimensional factor structure. The 2-factor model of MNWS-R had the best fit and the factors were labelled psychological symptoms (α = 0.86; rtt = 0.59) and associated somatic features (α = 0.64; rtt = 0.45). MNWS showed 1 factor; MNWS-R showed 2 relatively dependent factors. The results need to be replicated in smokers in withdrawal. © 2017 S. Karger AG, Basel.

Exploring the relationship between math anxiety and gender through implicit measurement

Math anxiety, defined as a negative affective response to mathematics, is suggested as a strong antecedent for the low visibility of women in the science and engineering workforce. However, the assumption of gender differences in math anxiety is still being studied and results are inconclusive, probably due to the use of explicit measures such as direct questionnaires. Thus, our primary objective was to investigate the effects of math anxiety on numerical processing in males and females by using a novel affective priming task as an indirect measure. Specifically, university students (23 males and 30 females) completed a priming task in which an arithmetic equation was preceded by one of four types of priming words (positive, neutral, negative, or related to mathematics). Participants were required to indicate whether the equation (simple math facts based on addition, subtraction, multiplication, or division) was true or false. People are typically found to respond to target stimuli more rapidly after presentation of an affectively related prime than after an affectively unrelated one. In the current study, shorter response latencies for positive as compared to negative affective primes were found in the male group. An affective priming effect was found in the female group as well, but with a reversed pattern. That is, significantly shorter response latencies were observed in the female group for negative as compared to positive targets. That is, for females, negative affective primes act as affectively related to simple arithmetic problems. In contrast, males associated positive affect with simple arithmetic. In addition, only females with lower or insignificant negative affect toward arithmetic study at faculties of mathematics and science. We discuss the advantages of examining pure anxiety factors with implicit measures which are free of response factors. In addition it is suggested that environmental factors may enhance the association between math achievements and math anxiety in females. PMID:23087633

Factors that influence thysanopteran wing diphenism are not well known. In these studies, the impact of food quality, mediated through nitrogen addition, and conspecific density was explored on the wing diphenism of an herbivorous thrips species (Anaphothrips obscurus Müller) (Thysanoptera: Thripidae). In the first study, nitrogen was added to timothy grass (Phleum pretense L.) (Poales: Poaceae) transplants, and naturally occurring thrips populations were caged on the plants. Thrips abundance and foliar nutrients were assessed every 2 wk. A separate factorial experiment in growth chambers explored the impact of both plant nitrogen addition and thrips abundance on wing diphenism. Thrips density was manipulated by adding either 3 or 40 thrips to potted and caged timothy. Thrips abundance and foliar nutrients were measured 58 d after treatment placement. Plant quality directly affected thrips wing diphenism independent of thrips density in both experiments. Near the end of the field cage experiment, density may have indirectly impacted wing diphenism. In both experiments, plant quality and thrips density interacted to affect thrips population abundance. Plant quality alone can affect thrips wing diphenism, but it remains unclear whether density alone can affect thrips wing diphenism. This is a unique and understudied system that will be useful to examine generalized theories on the negative interaction between reproduction and dispersal.

Sleep, recovery, and performance: the new frontier in high-performance athletics.

Samuels, Charles

2008-02-01

The relationship of sleep to post-exercise recovery (PER) and athletic performance is a topic of great interest because of the growing body of scientific evidence confirming a link between critical sleep factors, cognitive processes, and metabolic function. Sleep restriction (sleep deprivation), sleep disturbance (poor sleep quality), and circadian rhythm disturbance (jet lag) are the key sleep factors that affect the overall restorative quality of the sleep state. This article discusses these theoretic concepts, presents relevant clinical cases, and reviews pilot data exploring the prevalence of sleep disturbance in two groups of high-performance athletes.

Educational achievement is a key determinant of future life chances, but children growing up in poverty tend to do worse by many academic measures. Family, school, and neighborhood contextual characteristics may affect academic outcomes. In an attempt to explore neighborhood and individual level factors, we performed multilevel analyses to explain child's behavioral problems, repeat grade, average math and reading scores. Outcome measures were associated with specific neighborhood characteristics, above and beyond the effect of student/family level factors. The findings warrant further consideration of ecological interventions aiming to improve academic and behavioral outcomes of children living in poverty.

The general processes and controls associated with two distinct experimental paradigms are examined. Specific areas for research related to biotic production (food production) and biotic decomposition (waste management) are explored. The workshop discussions were directed toward Elemental cycles and the biological factors that affect the transformations of nutrients into food, of food material into waste, and of waste into nutrients were discussed. To focus on biological issues, the discussion assumed that (1) food production would be by biological means (thus excluding chemical synthesis), (2) energy would not be a limiting factor, and (3) engineering capacity for composition and leak rate would be adequate.

Urbanisation shapes behavioural responses to a pesticide.

2015-06-01

The degree of urbanisation is rapidly increasing worldwide. Due to anthropogenic impact, urban populations are exposed to higher levels of contaminants and higher temperatures. Despite this, urbanisation is a largely overlooked spatial component in ecotoxicology. We tested in a common garden rearing experiment whether replicated urban and rural populations of the damselfly Coenagrion puella differ in their vulnerability to sublethal levels of a widespread pesticide, chlorpyrifos, in terms of ecologically relevant behaviours (exploration behaviour, activity, boldness and food intake), and to what extent these patterns are affected by temperature (20 and 24°C). Except boldness, all behaviours were affected by previous pesticide exposure. While the pesticide did not affect exploration behaviour at 20°C, it was associated with increased exploration at 24°C, which may reflect an increased toxicity of chlorpyrifos at higher temperatures. Importantly, rural and urban larvae showed consistently different, sometimes even opposite behavioural responses to pesticide exposure. When exposed to the pesticide, rural larvae decreased activity and food intake at both temperatures; urban larvae instead increased activity at both temperatures and only reduced food intake at the high temperature. This suggests that urban larvae were less affected by the pesticide, which would be consistent with a scenario of local adaptation to higher contaminant levels. Our results highlight that urbanisation may be an important factor to arrive at a spatially explicit ecological risk assessment, and may be an ignored reason why studies on the same species may generate widely different vulnerabilities to pesticides.

2018-01-01

Sexual violence continues to be a significant public health problem worldwide with serious consequences for individuals and communities. The implementation of prevention strategies that address risk and protective factors for sexual violence at the community level are important components of a comprehensive approach, but few such strategies have been identified or evaluated. The current review explores one potential opportunity for preventing sexual violence perpetration at the community level: alcohol policy. Alcohol policy has the potential to impact sexual violence perpetration through the direct effects of excessive alcohol consumption on behavior or through the impact of alcohol and alcohol outlets on social organization within communities. Policies affecting alcohol pricing, sale time, outlet density, drinking environment, marketing, and college environment are reviewed to identify existing evidence of impact on rates of sexual violence or related outcomes, including risk factors and related health behaviors. Several policy areas with initial evidence of an association with sexual violence outcomes were identified, including policies affecting alcohol pricing, alcohol outlet density, barroom management, sexist content in alcohol marketing, and policies banning alcohol on campus and in substance-free dorms. We identify other policy areas with evidence of an impact on related outcomes and risk factors that may also hold potential as a preventative approach for sexual violence perpetration. Evidence from the current review suggests that alcohol policy may represent one promising avenue for the prevention of sexual violence perpetration at the community level, but additional research is needed to directly examine effects on sexual violence outcomes.

There is some concern that coal seam gas mining may affect health and wellbeing through changes in social determinants such as living and working conditions, local economy and the environment. The onward impact of these conditions on health and wellbeing is often not monitored to the same degree as direct environmental health impacts in the mining context, but merits attention. This study reports on the findings from a recurrent theme that emerged from analysis of the qualitative component of a comprehensive Health Needs Assessment (HNA) conducted in regional Queensland: that health and wellbeing of communities was reportedly affected by nearby coal seam gas (CSG) development beyond direct environmental impacts. Qualitative analysis was initially completed using the Framework Method to explore key themes from 11 focus group discussions, 19 in-depth interviews, and 45 key informant interviews with health and wellbeing service providers and community members. A key theme emerged from the analysis that forms the basis of this paper. This study is part of a larger comprehensive HNA involving qualitative and quantitative data collection to explore the health and wellbeing needs of three communities living in proximity to CSG development in regional Queensland, Australia. Communities faced social, economic and environmental impacts from the rapid growth of CSG development, which were perceived to have direct and indirect effects on individual lifestyle factors such as alcohol and drug abuse, family relationships, social capital and mental health; and community-level factors including social connectedness, civic engagement and trust. Outer regional communities discussed the effects of mining activity on the fabric of their town and community, whereas the inner regional community that had a longer history of industrial activity discussed the impacts on families and individual health and wellbeing. The findings from this study may inform future health service planning in regions affected by CSG in the development /construction phase and provide the mining sector in regional areas with evidence from which to develop social responsibility programs that encompass health, social, economic and environmental assessments that more accurately reflect the needs of the affected communities.

First year doctors experience of work related wellbeing and implications for educational provision

2014-01-01

Objectives: To explore factors which affect newly qualified doctors’ wellbeing and look at the implications for educational provision. Methods Data were collected by free association narrative interviews of nine Foundation doctors and analysed using a grounded theory approach. Two Foundation programme directors were interviewed to verify data validity. Results Two main themes emerged: newly qualified doctors’ wellbeing is affected by 1) personal experience and 2) work related factors. They start work feeling unprepared by medical school, work experience (“shadowing”) or induction programmes at the beginning of the post. Senior colleague support and feedback are much valued but often lacking with little discussion of critical incidents and difficult issues. Challenges include sick patients, prescribing, patient/relative communication and no consistent team structure. Working shift patterns affects personal and social life. Enjoyment and reward come from helping patients, feelings of making a difference or teaching medical students. Conclusions Whilst becoming familiar with their roles, newly qualified doctors search for identity and build up resilience. The support given during this process affects their wellbeing including coping with day to day challenges, whether posts are experienced as rewarding and how work influences their personal and social lives.

Current research evidence indicates that women should return to normal use of their arm after breast cancer surgery. However, it appears some women continue to hold the view that they are supposed to protect their arm from strenuous activities because of the risk of lymphoedema. Many factors contribute to women's perceptions about lymphoedema and their ability to use their affected arm, and it is the aim of this study to explore and understand these perceptions. A survey, based on the Protection Motivation Theory, has been developed and tested. The survey assesses whether subjective norms, fear and/or coping attributes predict women's intention to use their affected arm. In addition, the survey includes questions regarding cancer treatment and demographic characteristics, arm and chest symptoms, and arm function. Recruitment of 170 breast cancer survivors has begun at 3 cancer treatment sites in Sydney, Australia. This study will identify perceptions that help predict the extent women use their affected arm. The results will also determine whether upper limb impairments arise secondary to over-protection of the affected arm. Identification of factors that limit arm use will enable appropriate prevention and better provision of treatment to improve upper limb outcomes.

Early trauma, negative affect, and anxious attachment: the role of metacognition.

PubMed

Myers, Samuel G; Wells, Adrian

2015-01-01

Metacognition is linked to the etiology and maintenance of negative emotions and psychological disorder in the Self-Regulatory Executive Function Model. Although there is significant evidence supporting the model, little is currently known about the situational factors for developing dysfunctional metacognitions. The current study explored the hypothesis that early aversive experiences might be important and also tested if metacognitions could mediate the relationship between such experiences and psychological symptoms. Three hundred and fifty non-clinical adults completed a retrospective early trauma measure, as well as measures of current metacognitive beliefs, negative affect, and anxious attachment. Early emotional abuse positively and significantly correlated with several metacognitive belief dimensions but other forms of early trauma did not. Metacognition fully mediated the relationship between emotional abuse and negative affect. Anxious attachment was also positively and significantly associated with metacognitive beliefs and specific relationships remained after controlling for early emotional abuse and current negative affect. Findings are consistent with the ideas that: (i) early negative experiences, and emotional abuse in particular, could be a factor in the formation of problematic metacognitions and (ii) these metacognitions may be important in determining the effects of abuse on subsequent psychological symptoms.

Determinants of skilled birth attendants for delivery in Nepal.

2010-01-01

This review is to explore the factors affecting the uptake of skilled birth attendants for delivery and the issues associated with women's role and choices of maternal health care service for delivery in Nepal. Literature was reviewed across the globe and discussed in a Nepalese context. Delivery by Skilled Birth Attendance serves as an indicator of progress towards reducing maternal mortality worldwide, the fifth Millennium Development Goal. Nepal has committed to reducing its maternal mortality by 75% by 2015 through ensuring accessibility to the availability and utilisation of skilled care at every birth. The literature suggests that several socio-economic, cultural and religious factors play a significant role in the use of Skilled Birth Attendance for delivery in Nepal. Availability of transportation and distance to the health facility; poor infrastructure and lack of services; availability and accessibility of the services; cost and convenience; staff shortages and attitudes; gender inequality; status of women in society; women's involvement in decision making; and women's autonomy and place of residence are significant contributing factors for uptake of Skilled Birth Attendance for delivery in Nepal. The review found more quantitative research studies exploring the determinants of utilisation of the maternal health services during pregnancy in Nepal than qualitative studies. Findings of quantitative research show that different social demographic, economic, socio-cultural and religious factors are responsible for the utilisation of maternal health services but very few studies discussed how and why these factors are responsible for utilisation of skilled birth attendants in pregnancy. It is suggested that there is need for more qualitative research to explore the women's role and choice regarding use of skilled birth attendants services and to find out how and why these factors are responsible for utilisation of skilled birth attendants for delivery. Qualitative research will help further exploration of the issues and contribute to improvement of maternal health services.

As U.S. states increasingly focus on developing renewable energy resources, there is a need to track the progress of development, as well as the policies and support mechanisms being implemented to encourage this development. Beyond tracking, the evaluation of policy measures is necessary to determine their effectiveness, guide future efforts, and efficiently allocate resources. This report addresses each of these needs. It provides a detailed picture of the status of renewable energy development in each of the U.S. states using a variety of metrics and discusses the policies being used to encourage this development. The report then explores the contextmore » in which renewable energy development occurs by discussing the factors that can affect the uptake of power generation technologies. The analysis offers suggestions on how policies can be used to address these variables, which leads to tailored policy support that considers the specific circumstances within each state. The analysis presents results of several quantitative evaluation methods that have been designed to explore the link between policy implementation and actual development. Finally, the report discusses contextual factors, aside from policy, that affect renewable energy development. The report concludes with a summary of the main points from each chapter, discussion of next steps, and a list of resources.« less

Vanillic acid from Actinidia deliciosa impedes virulence in Serratia marcescens by affecting S-layer, flagellin and fatty acid biosynthesis proteins.

Serratia marcescens is one of the important nosocomial pathogens which rely on quorum sensing (QS) to regulate the production of biofilm and several virulence factors. Hence, blocking of QS has become a promising approach to quench the virulence of S. marcescens. For the first time, QS inhibitory (QSI) and antibiofilm potential of Actinidia deliciosa have been explored against S. marcescens clinical isolate (CI). A. deliciosa pulp extract significantly inhibited the virulence and biofilm production without any deleterious effect on the growth. Vanillic acid was identified as an active lead responsible for the QSI activity. Addition of vanillic acid to the growth medium significantly affected the QS regulated production of biofilm and virulence factors in a concentration dependent mode in S. marcescens CI, ATCC 14756 and MG1. Furthermore vanillic acid increased the survival of Caenorhabditis elegans upon S. marcescens infection. Proteomic analysis and mass spectrometric identification of differentially expressed proteins revealed the ability of vanillic acid to modulate the expression of proteins involved in S-layers, histidine, flagellin and fatty acid production. QSI potential of the vanillic acid observed in the current study paves the way for exploring it as a potential therapeutic candidate to treat S. marcescens infections.

IVF treatment is usually stressful for patients, but individual differences in emotional response do exist. Differences in the stress response may be related to reproductive outcomes as well as to the development of psychiatric problems. This review collates research exploring which psychosocial factors (e.g. personality traits and coping strategies) are associated with the emotional adjustment of IVF patients. The aim is to reveal what is currently known about risk and protective factors for coping with the stress of IVF treatment and where further enquiry would be most beneficial. The databases, MEDLINE/PUBMED (US National Library of Medicine), PsycINFO (American Psychological Association), Web of Science (Social Sciences Citation Index) and EMbase, were searched from 1978 to September 2012 using relevant key words. All published peer-reviewed studies exploring associations between psychosocial factors and emotional adjustment outcomes were considered for inclusion. There were 23 studies identified for review. One-third of the psychosocial factors explored were found to be significantly related to emotional adjustment outcome measures. Neuroticism and the use of escapist coping strategies were positively associated with distress by multiple studies. Social support was negatively associated with distress by several studies. A number of other psychosocial variables appear to be associated with distress, including self-criticism, dependency, situation appraisals and attachment style, but these have only been explored by one or two studies at most. There is a paucity of research using positive emotional outcome measures (e.g. well-being, positive affect, happiness or life satisfaction) to quantify emotional adjustment. Whilst some psychosocial variables appear to be consistently associated with distress for IVF patients, two-thirds of the variables tested to date do not appear to be associated with emotional adjustment. This review highlights key psychosocial factors to assist the identification of patients at high risk of psychological distress. These findings highlight at least two psychological factors that may be amenable to alteration with psychological or educational interventions. Future work should explore whether experimental manipulation of such psychosocial factors can provide effective stress reduction in this clinical context. © The Author 2014.

Understanding what matters most to people with multiple myeloma: a qualitative study of views on quality of life

PubMed Central

2014-01-01

Background Multiple myeloma is an incurable haematological cancer that affects physical, psychological and social domains of quality of life (QOL). Treatment decisions are increasingly guided by QOL issues, creating a need to monitor QOL within clinical practice. The development of myeloma-specific QOL questionnaires has been limited by a paucity of research to fully characterise QOL in this group. Aims of the present study are to (1) explore the issues important to QOL from the perspective of people with multiple myeloma, and (2) explore the views of patients and clinical staff on existing QOL questionnaires and their use in clinical practice. Methods The ‘Issues Interviews’ were semi-structured qualitative interviews to explore the issues important to QOL in a purposive sample of myeloma patients (n = 20). The ‘Questionnaire Interviews’ were semi-structured qualitative interviews in a separate purposive sample of myeloma patients (n = 20) to explore views on existing QOL questionnaires and their clinical use. Two patient focus groups (n = 7, n = 4) and a focus group of clinical staff (n = 6) complemented the semi-structured interviews. Thematic content analysis resulted in the development of a theoretical model of QOL in myeloma. Results Main themes important to QOL were Biological Status, Treatment Factors, Symptoms Status, Activity & Participation, Emotional Status, Support Factors, Expectations, Adaptation & Coping and Spirituality. Symptoms had an indirect effect on QOL, only affecting overall QOL if they impacted upon Activity & Participation, Emotional Status or Support Factors. This indirect relationship has implications for the design of QOL questionnaires, which often focus on symptom status. Health-service factors emerged as important but are often absent from QOL questionnaires. Sexual function was important to patients and difficult for clinicians to discuss, so inclusion in clinical QOL tools may flag hidden problems and facilitate better care. Patients and staff expressed preferences for questionnaires to be no more than 2 pages long and to include a mixture of structured and open questions to focus the goals of care on what is most important to patients. Conclusion Existing QOL questionnaires developed and validated for use in myeloma do not capture all that is important to patients and may not be well suited to clinical use. PMID:25005145

Design, development and validation of a new laryngo-pharyngeal endoscopic esthesiometer and range-finder based on the assessment of air-pulse variability determinants.

Laryngo-pharyngeal mechano-sensitivity (LPMS) is involved in dysphagia, sleep apnea, stroke, irritable larynx syndrome and cough hypersensitivity syndrome among other disorders. These conditions are associated with a wide range of airway reflex abnormalities. However, the current device for exploring LPMS is limited because it assesses only the laryngeal adductor reflex during fiber-optic endoscopic evaluations of swallowing and requires a high degree of expertise to obtain reliable results, introducing intrinsic expert variability and subjectivity. We designed, developed and validated a new air-pulse laryngo-pharyngeal endoscopic esthesiometer with a built-in laser range-finder (LPEER) based on the evaluation and control of air-pulse variability determinants and on intrinsic observer variability and subjectivity determinants of the distance, angle and site of stimulus impact. The LPEER was designed to be capable of delivering precise and accurate stimuli with a wide range of intensities that can explore most laryngo-pharyngeal reflexes. We initially explored the potential factors affecting the reliability of LPMS tests and included these factors in a multiple linear regression model. The following factors significantly affected the precision and accuracy of the test (P < 0.001): the tube conducting the air-pulses, the supply pressure of the system, the duration of the air-pulses, and the distance and angle between the end of the tube conducting the air-pulses and the site of impact. To control all of these factors, an LPEER consisting of an air-pulse generator and an endoscopic laser range-finder was designed and manufactured. We assessed the precision and accuracy of the LPEER's stimulus and range-finder according to the coefficient of variation (CV) and by looking at the differences between the measured properties and the desired values, and we performed a pilot validation on ten human subjects. The air-pulses and range-finder exhibited good precision and accuracy (CV < 0.06), with differences between the desired and measured properties at <3 % and a range-finder measurement error of <1 mm. The tests in patients demonstrated obtainable and reproducible thresholds for the laryngeal adductor, cough and gag reflexes. The new LPEER was capable of delivering precise and accurate stimuli for exploring laryngo-pharyngeal reflexes.

Case-control studies have consistently associated psychological factors with chronic pain in general and with temporomandibular disorders (TMD) specifically. However, only a handful of prospective studies has explored whether pre-existing psychological characteristics represent risk factors for first-onset TMD. The current findings derive from the prospective cohort study of the Orofacial Pain Prospective Evaluation and Risk Assessment (OPPERA) cooperative agreement. For this study, 3,263 TMD-free participants completed a battery of psychological instruments assessing general psychological adjustment and personality, affective distress, psychosocial stress, somatic symptoms, and pain coping and catastrophizing. Study participants were then followed prospectively for an average of 2.8 years to ascertain cases of first-onset of TMD, and 2,737 provided follow-up data and were considered in the analyses of TMD onset. In bivariate and demographically-adjusted analyses, several psychological variables predicted increased risk of first-onset TMD, including reported somatic symptoms, psychosocial stress, and affective distress. Principal component analysis of 26 psychological scores was used to identify latent constructs, revealing four components: stress and negative affectivity, global psychological and somatic symptoms, passive pain coping, and active pain coping. In multivariable analyses, global psychological and somatic symptoms emerged as the most robust risk factor for incident TMD. These findings provide evidence that measures of psychological functioning can predict first-onset of TMD. Future analyses in the OPPERA cohort will determine whether these psychological factors interact with other variables to increase risk for TMD onset and persistence. PMID:24275225

Perception of earthquake risk in Taiwan: effects of gender and past earthquake experience.

Kung, Yi-Wen; Chen, Sue-Huei

This study explored how individuals in Taiwan perceive the risk of earthquake and the relationship of past earthquake experience and gender to risk perception. Participants (n= 1,405), including earthquake survivors and those in the general population without prior direct earthquake exposure, were selected and interviewed through a computer-assisted telephone interviewing procedure using a random sampling and stratification method covering all 24 regions of Taiwan. A factor analysis of the interview data yielded a two-factor structure of risk perception in regard to earthquake. The first factor, "personal impact," encompassed perception of threat and fear related to earthquakes. The second factor, "controllability," encompassed a sense of efficacy of self-protection in regard to earthquakes. The findings indicated prior earthquake survivors and females reported higher scores on the personal impact factor than males and those with no prior direct earthquake experience, although there were no group differences on the controllability factor. The findings support that risk perception has multiple components, and suggest that past experience (survivor status) and gender (female) affect the perception of risk. Exploration of potential contributions of other demographic factors such as age, education, and marital status to personal impact, especially for females and survivors, is discussed. Future research on and intervention program with regard to risk perception are suggested accordingly. © 2012 Society for Risk Analysis.

Introduction While the routine childhood immunization program might be affected by several factors, its identification using qualitative evidence of caretakers is generally minimal. This article explores the various factors and misperceptions of routine childhood immunization service uptake in Ethiopia and provides possible recommendations to mitigate them. Methods In this study, we used a qualitative multiple case study design collecting primary data from 63 focus group discussions (FGDs) conducted with a purposefully selected sample of children's caretakers (n = 630). Results According to the results of this study, the use of routine childhood immunization is dependent on four major factors: caretakers' behavior, family characteristics, information and communication and immunization service system. In addition, the participants had some misperceptions about routine childhood immunization. For example, immunization should be taken when the child gets sick and a single dose vaccine is enough for a child. These factors and misperceptions are complex and sometimes context-specific and vary between categories of caretakers. Conclusion Our interpretations suggest that no single factor affects immunization service uptake alone in a unique way. Rather, it is the synergy among the factors that has a collective influence on the childhood immunization system. Therefore, intervention efforts should target these multiple factors simultaneously. Importantly, this study recommends improving the quality of existing childhood immunization services and building awareness among caretakers as crucial components. PMID:29675124

Malaria remains a global health issue with the burden unevenly distributed to the disadvantage of the developing countries of the world. Poverty contributes to the malaria burden as it has the ability to affect integral aspects of malaria control. There have been renewed efforts in the global malaria control, resulting in reductions in the global malaria burden over the last decade. However, the development of resistance to artemisinin-based combination therapy threatens the sustainability of the present success in malaria control. Anti-malarial drug use practices/behaviours remain very important drivers of drug resistance. This study adopted a social epidemiological stance in exploring the underlying socioeconomic factors that determine drug use behaviours promoting anti-malarial drug resistance. A qualitative approach, involving the use of interviews, was used in this inquiry to explore the existing anti-malarial drug use practices in the Nigerian population; and the different socioeconomic factors influencing the behaviours. The significant malaria treatment behaviours influenced by socioeconomic factors in this study were the practice of 'mixing' drugs for malaria treatment, presumptive treatment, sharing of malaria treatment course, and the use of anti-malaria monotherapies. All the rural dwellers in this study reported they have mixed drugs for malaria treatment. When symptoms were experienced, socio-economic factors, like type of settlement, income level and occupation, tended to determine the treatment behaviour and, therefore, informed and determined the experience of the illness. Social and economic contexts can influence behaviours as they contribute in shaping norms and in creating opportunities that promote certain behaviours. As shown in this study, income level and type of settlement, as structural factors, affect the decision on where to seek malaria treatment and whether or not a malaria diagnostic test will be used prior to treatment. One of the dangers of using the mixed anti-malarial drugs is that it offers a safe route for the sale of expired and fake anti-malarial drugs as the mixed drugs are not sold or dispensed in their original packets. Population-wide improvements in income, education, environmental and structural conditions of rural dwellers in malaria-endemic settings will encourage behavioural change on how anti-malarial drugs are used.

This study introduces a new measure of the perceived utility of emotion, which is the degree to which emotions are perceived to be useful in achieving goals. In this study, we administered this new measure, the Perceived Affect Utility Scale (PAUSe), to a sample of 142 European American and 156 East Asian American college students. Confirmatory factor analyses provided support for a new, culturally informed parsing of emotion and for perceived utility of emotion to be distinguishable from ideal affect, a related but separate construct. Next, we explored the potential importance of perceived utility of emotion in cultural research. Through path analyses, we found that: (a) culturally relevant variables (e.g., independence) played a mediating role in the link between ethnic group and perceived utility of emotion; and (b) perceived utility of emotion played a mediating role in the link between culturally relevant variables and ideal affect. In particular, perceived utility of self-centered emotions (e.g., pride) was found to be associated with independence and ideal affect of those same emotions. In contrast, perceived utility of other-centered emotions (e.g., appreciation) was found to be associated with interdependence, dutifulness/self-discipline, and ideal affect of those same emotions. Implications for perceived utility of emotion in understanding cultural factors are discussed.

Adolescent smoking and friendship networks are related in many ways that can amplify smoking prevalence. Understanding and developing interventions within such a complex system requires new analytic approaches. We draw on recent advances in dynamic network modeling to develop a technique that explores the implications of various intervention strategies targeted toward micro-level processes. Our approach begins by estimating a stochastic actor-based model using data from one school in the National Longitudinal Study of Adolescent Health. The model provides estimates of several factors predicting friendship ties and smoking behavior. We then use estimated model parameters to simulate the coevolution of friendship and smoking behavior under potential intervention scenarios. Namely, we manipulate the strength of peer influence on smoking and the popularity of smokers relative to nonsmokers. We measure how these manipulations affect smoking prevalence, smoking initiation, and smoking cessation. Results indicate that both peer influence and smoking-based popularity affect smoking behavior and that their joint effects are nonlinear. This study demonstrates how a simulation-based approach can be used to explore alternative scenarios that may be achievable through intervention efforts and offers new hypotheses about the association between friendship and smoking.

Most of the extant literature on borderline personality disorder has focused on the course, consequences, and correlates of this disorder among adults. However, little is known about childhood borderline personality (BP) features, or the factors associated with the emergence of BP pathology in childhood. A greater understanding of childhood BP features and associated risk factors has important implications for the development of primary and secondary prevention programs. The goal of the present study was to examine the interrelationships among two BP-relevant traits (affective dysfunction and impulsivity), a BP-relevant environmental stressor (emotional abuse), and BP features in a sample of 225 children aged 11 to 14 years. Results provide support for the role of both trait vulnerabilities and environmental stressors in childhood BP features. Further, findings highlight the moderating role of affective dysfunction in the relationship between emotional abuse and childhood BP features. PMID:21658531

Knowledge about factors that affect participation, as preference of activities, has major intervention implications. To evaluate culture and gender effects on Israeli Jewish and Druze children's preference of activities performed outside mandated school. This study used the "Preference Assessment of Children" (PAC) (King et al., 2004). On most scales, the Jewish children showed significantly less interest in activities than the Druze children. Among the Jews, girls showed higher preference in most PAC scales than boys while among the Druze girls showed higher preference than the boys only in social skills. Culture and gender may influence children's preference of activity. More studies should elaborate the knowledge about individuals' preferred activities; understanding the factors that affect these preferences may enhance occupational therapy evaluation and intervention processes. Canadian occupational therapists, as health care professionals in a multicultural society, must develop cultural competency and explore people's experience as cultural beings.

Fibromyalgia (FM) affects 1% to 5% of the population, and approximately 90% of the affected individuals are women. FM patients experience impaired quality of life and the disorder places a considerable economic burden on the medical care system. With the recognition of FM as a major health problem, many recent studies have evaluated the pathophysiology of FM. Although the etiology of FM remains unknown, it is thought to involve some combination of genetic susceptibility and environmental exposure that triggers further alterations in gene expression. Because FM shows marked familial aggregation, most previous research has focused on genetic predisposition to FM and has revealed associations between genetic factors and the development of FM, including specific gene polymorphisms involved in the serotonergic, dopaminergic, and catecholaminergic pathways. The aim of this review was to discuss the current evidence regarding genetic factors that may play a role in the development and symptom severity of FM. PMID:26306300

Social anxiety (SA) following traumatic brain injury (TBI) has the potential to affect an individual's general psychological well-being and social functioning, however little research has explored factors associated with its development. The present study used hierarchical multiple regression to investigate the demographic, clinical and psychological factors associated with SA following TBI. A sample of 85 people who experienced TBI were recruited through social media websites and brain injury services across the North-West of England. The overall combined biopsychosocial model was significant, explaining 52-54.3% of the variance in SA (across five imputations of missing data). The addition of psychological variables (self-esteem, locus of control, self-efficacy) made a significant contribution to the overall model, accounting for an additional 12.2-13% of variance in SA above that explained by demographic and clinical variables. Perceived stigma was the only significant independent predictor of SA (B = .274, p = .005). The findings suggest that psychological variables are important in the development of SA following TBI and must be considered alongside clinical factors. Furthermore, the significant role of stigma highlights the need for intervention at both an individualised and societal level.

As climate change increases the pressures on arid ecosystems by changing timing and amount of rainfall, understanding the ways in which human management choices affect the resilience of these systems becomes key to their sustainability. On marginal farmland in Mazvihwa, Midlands Province, the historical carrying capacity of livestock has been consistently surprisingly high. We explore this phenomenon by building an agent-based model in NetLogo from a wealth of long-term data generated by the community-based participatory research team of The Muonde Trust, a Zimbabwean non-governmental organization. We combine the accumulated results of 35 years of indigenous and local knowledge with national datasets such as rainfall records. What factors keep the carrying capacity high? What management choices can maintain crops, livestock, and woodland at levels necessary for the community's survival? How do these choices affect long-term sustainability, and does increasing resilience at one scale reduce resilience at another scale? We use our agent-based model to explore the feedbacks between crops, livestock, and woodland and the impacts of various human choices as well as temporal and spatial ecological variation. By testing different scenarios, we disentangle the complex interactions between these components. We find that some factors out of the community's control can strongly affect the sustainability of the system through times of drought, and that supplementary feed may maintain livestock potentially at the expense of other resources. The challenges to resilience encountered by the farmers in Mazvihwa are not unique - many indigenous and rural people face drought and the legacies of colonialism, which contribute to lowered resilience to external challenges such as climate change, epidemics, and political instability. Using the agent-based model as a tool for synthesis and exploration initiates discussion about resilience-enhancing management choices for Mazvihwa's farmer-researchers.

Tuberculosis (TB) is a major global health problem, commonly seen in underdeveloped countries. The probability of contracting the disease is significantly higher among the economically vulnerable and the socially disadvantaged. Risk factors associated with TB can also change over time. In the Sri Lankan context, no study has explored how these factors impact patients. Therefore, we aimed to explore social status, associated risk factors and lifestyle changes during the treatment period of TB patients attending a tertiary respiratory center in Colombo, Sri Lanka. The descriptive cross-sectional study was conducted in 2011. The study population consisted of diagnosed tuberculosis patients above the age of 15 years. Patient records were retrieved from the TB patient registry for the Colombo district. Systematic sampling was used to identify patients to be invited to the study. An interviewer-administered questionnaire was used for data collection. Data were collected on social status (example, level of education, employment, and income), associated risk factors (example, smoking and alcohol consumption, contact history, narcotic drug use) and lifestyle changes during treatment (example, employment status, social interactions). The analysis included a logistic regression model to explore the association between social status and risk factors. The total number of patients included in the study was 425. Tuberculosis was found to be strongly prevalent among participants from the lower socio-economic status. It was also common in participants with a low level of education, unemployed, if employed, those who are engaged in unskilled employment and have low levels of income. Risk factors associated with the patients were smoking, alcohol consumptions, narcotic drug use, imprisonment, close contact history with active TB patients and chronic medical conditions. Changes in employment and the reduction of social-interactions were the main lifestyle changes of the participants occurred during the treatment period. The analysis also showed positive correlation between low-level social status and sputum smear infectivity, and use of dangerous drugs. Even after adjusting for confounders, tuberculosis negatively affected social interactions and income levels of participants from the low social status. Low socio-economic status negatively affected the lifestyle and social interactions of patients during the treatment period. Though competent treatment programs exist in Sri Lanka, it is still important to identify and mitigate risk factors associated with tuberculosis patients. A comprehensive multi-disciplinary approach considering patient lifestyle, and the implications of the disease and treatment on social interactions may strengthen the current preventive strategies.

Recovery of Weak Factor Loadings When Adding the Mean Structure in Confirmatory Factor Analysis: A Simulation Study

This article extends previous research on the recovery of weak factor loadings in confirmatory factor analysis (CFA) by exploring the effects of adding the mean structure. This issue has not been examined in previous research. This study is based on the framework of Yung and Bentler (1999) and aims to examine the conditions that affect the recovery of weak factor loadings when the model includes the mean structure, compared to analyzing the covariance structure alone. A simulation study was conducted in which several constraints were defined for one-, two-, and three-factor models. Results show that adding the mean structure improves the recovery of weak factor loadings and reduces the asymptotic variances for the factor loadings, particularly for the models with a smaller number of factors and a small sample size. Therefore, under certain circumstances, modeling the means should be seriously considered for covariance models containing weak factor loadings. PMID:26779071

Healthy lifestyles help to prevent coronary heart disease (CHD) but outcomes from secondary prevention interventions which support lifestyle change have been disappointing. This study is a novel, in-depth exploration of patient factors affecting lifestyle behaviour change within an intervention designed to improve secondary prevention for patients with CHD in primary care using personalised tailored support. We aimed to explore patients' perceptions of factors affecting lifestyle change within a trial of this intervention (the SPHERE Study), using semi-structured, one-to-one interviews, with patients in general practice. Interviews (45) were conducted in purposively selected general practices (15) which had participated in the SPHERE Study. Individuals, with CHD, were selected to include those who succeeded in improving physical activity levels and dietary fibre intake and those who did not. We explored motivations, barriers to lifestyle change and information utilised by patients. Data collection and analysis, using a thematic framework and the constant comparative method, were iterative, continuing until data saturation was achieved. We identified novel barriers to lifestyle change: such disincentives included strong negative influences of social networks, linked to cultural norms which encouraged consumption of 'delicious' but unhealthy food and discouraged engagement in physical activity. Findings illustrated how personalised support within an ongoing trusted patient-professional relationship was valued. Previously known barriers and facilitators relating to support, beliefs and information were confirmed. Intervention development in supporting lifestyle change in secondary prevention needs to more effectively address patients' difficulties in overcoming negative social influences and maintaining interest in living healthily.

Type 1 diabetes is a lifelong condition for children and their parents, the management for which imposes a vast responsibility. This study explores the mediating factors that affect Iranian parents' coping processes with their children's type 1 diabetes. Research was conducted using the grounded theory method. Participants were selected purposefully, and we continued with theoretical sampling. Constant comparative analysis was used to analyze the data. The mediating factors of the parental coping process with their child's diabetes consist of the child's cooperation, crises and experiences, economic challenges, and parental participation in care. Findings highlight the necessity of well-informed nurses with insightful understanding of the mediating factors in parental coping with juvenile diabetes in order to meet the particular needs of this group.

Behavioural factors affecting physical health of the New Zealand Maori.

A major factor in the aetiology of illness is the behaviour of individuals with regard to certain risks and hazards of the environment. The Maori of New Zealand have been shown to be at greater risk of illness and death than their non-Maori counterparts. It is estimated that a significant proportion of this excess morbidity and mortality can be attributed to at least four behavioural factors: smoking, obesity, alcohol use and accidents. This paper examines the inter-cultural differences in these factors, both from a contemporary and an historical perspective. Some of the reasons for the continuation of these adverse patterns of behaviour are explored, in particular the role of psycho-cultural stress. Some possible mechanisms of effecting behavioural change in modern Maori society are discussed.

Human factors is a critical discipline for human spaceflight. Nearly every human factors research area is relevant to space exploration -- from the ergonomics of hand tools used by astronauts, to the displays and controls of a spacecraft cockpit or mission control workstation, to levels of automation designed into rovers on Mars, to organizational issues of communication between crew and ground. This chapter focuses more on the ways in which the space environment (especially altered gravity and the isolated and confined nature of long-duration spaceflight) affects crew performance, and thus has specific novel implications for human factors research and practice. We focus on four aspects of human performance: neurovestibular integration, motor control and musculo-skeletal effects, cognitive effects, and behavioral health. We also provide a sampler of recent human factors studies from NASA.

The decreasing availability of surgical physicians is a concern in most countries. In the past decade, total physician manpower in Taiwan increased by 12%, but the number of surgical physicians decreased by 11%. Medical students are not inclined to choose surgery as a career--this study examines the factors involved in students' career choices. This study was conducted from January 2011 to April 2011. In total, 401 interns successfully completed questionnaires; this population makes up 34% of all interns in Taiwan. The structural questionnaire was designed to investigate factors affecting specialty decisions, with additional open-ended questions to investigate students' preferences in career specialty. Based on the research findings, the 3 most relevant factors in decreasing order of priority are personal interest, career-oriented lifestyle, and specialty characteristics (including workload and stress). For students likely to become surgical physicians, concerns about the work environment include the balance between work and family, wages that are incompatible with the workload, and the shortage of manpower on duty. Addressing the following concerns would increase medical students' likelihood of choosing a career in surgery: the need for a facilitator to help mitigate medical disputes and legal problems, decreased work hours, and decreased on-call duty hours. This study shows both motivating and discouraging factors affecting whether medical students choose surgery as a career. The purpose of this study is to strengthen the incentives for medical students to choose surgery as a career and to minimize the influence of factors that negatively affect such a choice. © The Author(s) 2014.

The International Classification of Functioning, Disability and Health (ICF) proposes three main constructs, impairment (I), activity limitation (A) and participation restriction (P). The ICF model allows for all paths between the constructs to be explored, with significant paths likely to vary for different conditions. The relationships between I, A and P have been explored in some conditions but not previously in people with osteoarthritis prior to joint replacement. The aim of this paper is to examine these relationships using separate measures of each construct and structural equation modelling. A geographical cohort of 413 patients with osteoarthritis about to undergo hip and knee joint replacement completed the Aberdeen measures of Impairment, Activity Limitation and Participation Restriction (Ab-IAP). Confirmatory factor analysis was used to test the three factor (I, A, P) measurement model. Structural equation modelling was used to explore the I, A and P pathways in the ICF model. There was support from confirmatory factor analysis for the three factor I, A, P measurement model. The structural equation model had good fit [S-B Chi-square = 439.45, df = 149, CFI robust = 0.91, RMSEA robust = 0.07] and indicated significant pathways between I and A (standardised coefficient = 0.76 p < 0.0001) and between A and P (standardised coefficient = 0.75 p < 0.0001). However, the path between I and P was not significant (standardised coefficient = 0.01). The significant pathways suggest that treatments and interventions aimed at reducing impairment, such as joint replacement, may only affect P indirectly, through A, however, longitudinal data would be needed to establish this.

Many studies have examined childhood and adolescent obesity, but few have examined young adults and the effect of their home and current living environments on prevalence rates. The present study explores contextual factors affecting overweight and obesity among university students in China and, in particular, focuses on how the SES-obesity relationship varies across different geographical contexts. Participants were 11,673 students, who were identified through a multistage survey sampling process conducted in 50 universities. Individual data was obtained through a self-administered questionnaire, and contextual variables were retrieved from a national database. Multilevel logistic regression models were used to examine urban and regional variations in overweight and obesity. Overall the prevalence of overweight and obesity in the study sample was 9.5% (95% CI 7.7, 11.3%). After controlling for individual factors, both attributes of the home location (regional GDP per capita and rurality) and the current university location (city population) were found to be important, thus suggesting that the different origins of students affect current levels of obesity. At the individual level, while students with more financial resources were more likely to be obese, the extent of this relationship was highly dependent upon area income and city size. The results of this study add important insights about the role of contextual factors affecting overweight and obesity among young adults and indicate a need to take into account both past as well as present environmental influences when considering the role of contextual factors in models of the nutrition transition.

Context: Choosing a career is an important decision for each individual, which is affected by many different factors. The process of entering nursing, as one of the pivotal healthcare discipline, certainly affects quality of care, and retention of nurses in the profession. Aims: Exploring factors affecting the students’ decision to enter nursing. Setting and Design: This qualitative content analysis was carried at the school of Nursing and Midwifery of Tehran University of medical sciences. Materials and Methods: The semi structured interview method was used to conduct this qualitative study on 11 nursing freshmen in 2010. We transcribed the interviews verbatim and analyzed them using the conventional content analysis approach. Results: Four main categories, reflecting the factors affecting the participants’ decision to enter nursing emerged in this study: Capabilities of the profession, coercion, having an interest in the medical and allied health fields, and receiving positive feedbacks. The participants had tried to gather information about nursing through different sources, including nurses and other health care professionals, counselors and Internet, which almost all the time, yielded to no useful information and sometimes with negative feedback. Conclusions: Findings revealed that, unlike other countries, few participants had entered nursing with a real interest in helping and caring for others, and other factors such as having an interest in the medical and allied health fields, coercion, and good employment opportunities were the most important motives. Students’ lack of knowledge about the profession deserves special attention. Nursing managers’ should try to introduce the reality of nursing to the public and as a result, attract more competent students to the profession. PMID:23983730

Unraveling the Determinants of Protrusion Formation

A computerized morphometric classification technique based on latent factors reveals major protrusion classes: factors 4, 5, and 7. Previous work showed that factor 4 represented filopodia, 5 the distribution of lamellar cytoplasm, and 7 a blunt protrusion. We explore the relationship of focal contact (FC) characteristics and their integrated actin cables to factors values. The results show that FC maturation/cytoskeletal integration affects factor 5, because FC elongation/integration was correlated with its values. On the contrary, 7 values decreased with maturation, so cable or FC size or their integration must be restricted to form these protrusions. Where integration did occur, the cables showed distinctive size and orientation, as indicated by correlation of 7 values with FC shape. Results obtained with myosin inhibitors support the interpretation that a central, isometric, contractile network puts constraints on both factor 5 and 7 protrusions. We conclude that cells establish functional domains by rearranging the cytoskeleton. PMID:22500172
