The purpose of this study was to investigate the effects of holding external loads on postural sway during upright stance across age decades. Sixty-five healthy adults (females, n = 35), aged 18-80 years were assessed in four conditions; (1) standing without holding a load, holding a load corresponding to 5% body mass in the (2) left hand, (3) right hand and (4) both hands. The centre of pressure (COP) path length and anteroposterior and mediolateral COP displacement were used to indirectly assess postural sway. External loading elicited reductions in COP measures of postural sway in older age groups only (P  0.05). Holding external loads during standing is relevant to many activities of daily living (i.e. holding groceries). The reduction in postural sway may suggest this type of loading has a stabilising effect during quiet standing among older adults. Copyright © 2017 Elsevier Ltd. All rights reserved.

In direct hoisting work in suspension bridge construction, since a cable crane directly hoists a bridge beam block put on a barge on the sea, precise fixed position holding function is required for a barge. The control system was then designed on the basis of an ILQ control theory, and the effect of change in time constant as design parameter on fixed position holding performance was studied. In addition, the critical disturbance for fixed position holding control was studied through numerical simulation under various disturbance conditions using the above designed control system. As a result, in the design of control systems on the basis of an ILQ control theory, the precise control system could be designed by diminishing, in particular, the time constant for state variable around a z axis among time constants according to the extent of disturbance. The control performance was largely affected by response delay period from sensing of disturbance to beginning of control. 3 refs., 7 figs., 2 tabs.

The group of entities under the control of parent, so called holding, is arisen as the result and the most often used form of the business concentration nowadays. The paper is focused to find special tasks of parent company for to preserve effective unified economic control in the management-holding. The unified economic control the holding exists in the conditions of the main conflict of interest - holding is not a legal but economic unit and the connected companies into it have a legal autonomy with the economic dependence. The unified economic control limits the financial independence of every individual company of the holding. The attention in the paper is concentrated to the management concept of the parent control, i.e. the parent company supervises the control of intragroup flows and all of subsidiaries production activities.

Does imminent threat capture and hold attention?

According to models of attention and emotion, threat captures and holds attention. In behavioral tasks, robust evidence has been found for attentional holding but not for attentional capture by threat. An important explanation for the absence of attentional capture effects is that the visual stimuli used posed no genuine threat. The present study investigated whether visual cues that signal an aversive white noise can elicit attentional capture and holding effects. Cues presented in an attentional task were simultaneously provided with a threat value through an aversive conditioning procedure. Response latencies showed that threatening cues captured and held attention. These results support recent views on attention to threat, proposing that imminent threat captures attention in everyone.

To treat low-back pain, various spinal stability exercises are commonly used to improve trunk muscle function and strength. Because human movement for normal daily activity occurs in multi-dimensions, the importance of exercise in multi-dimensions or on unstable surfaces has been emphasized. Recently, a motorized rotating platform (MRP) for facilitating multi-dimensions dynamic movement was introduced for clinical use. However, the abdominal muscle activity with this device has not been reported. The purpose of this study was to compare the abdominal muscle activity (rectus abdominis, external and internal oblique muscles) during an active single-leg-hold (SLH) exercise on a floor (stable surface), foam roll, and motorized rotating platform (MRP). Thirteen healthy male subjects participated in this study. Using electromyography, the abdominal muscle activity was measured while the subjects performed SLH exercises on floor (stable surface), foam roll, and MRP. There were significant differences in the abdominal muscle activities among conditions (P.05) (Fig. 2). After the Bonferroni correction, however, no significant differences among conditions remained, except for differences in both side IO muscle activity between the floor and foam roll conditions (padjexercises on a foam roll and MRP is more effective increased activities of both side of RA and IO, and Rt. EO compared to floor condition. However, there were no significant differences in abdominal muscles activity in the multiple comparison between conditions (mean difference were smaller than the standard deviation in the abdominal muscle activities) (padj>0.017), except for differences in both side IO muscle activity between the floor (stable surface) and foam roll (padj<0.017) (effect size: 0.79/0.62 (non-supporting/supporting leg) for foam-roll versus floor).

Kim, Hyeong Koo; Kim, Kyu Tae

1996-07-01

Hold down plate for the INGLE fuel which has been designed for high performance in the standpoints of thermal margin and structural integrity compared to current fuel for YGN 3/4 and UCN 3/4 has been developed and its structural integrity has been verified based on the eh stress analysis. The design feature of the developed hold down plate has not only perfect compatibility with the reactor internals of Korea standard reactor, but also brand-new locking mechanism between upper tie plate and guide tubes. This locking mechanism introduced to the INGLE fuel provides very simple and reliable reconstitutability. In this report, finite element stress analysis with the aid of the ANSYS code as a solver and the MSC/PATRAN code as a pre and post processor were performed to verify structural integrity of the hold down plate considering various load cases which seem to be applied to the hold down plate during its lifetime. Based on the analysis results, the developed hold down plate for INGLE fuel sustains structural integrity under considered load conditions. 3 tabs., 16 figs., 9 refs. (Author)

In this work, it was concluded that higher drying temperature conditions originate lower rehydration ratio and consequent lower water holding capacity possibly due to a higher physical damage in the algae tissues. It was also observed that both Codium species have higher values for these two parameters than Ulva lactuca, under the same rehydration conditions.

Full Text Available OBJECTIVE: To examine the prevalence of medical conditions and use of health services among young adults with Down syndrome and describe the impact of these conditions upon their lives. METHODS: Using questionnaire data collected in 2011 from parents of young adults with Down syndrome we investigated the medical conditions experienced by their children in the previous 12 months. Univariate, linear and logistic regression analyses were performed. RESULTS: We found that in addition to the conditions commonly experienced by children with Down syndrome, including eye and vision problems (affecting 73%, ear and hearing problems (affecting 45%, cardiac (affecting 25% and respiratory problems (affecting 36%, conditions also found to be prevalent within our young adult cohort included musculoskeletal conditions (affecting 61%, body weight (affecting 57%, skin (affecting 56% and mental health (affecting 32% conditions and among young women menstrual conditions (affecting 58%. Few parents reported that these conditions had no impact, with common impacts related to restrictions in opportunities to participate in employment and community leisure activities for the young people, as well as safety concerns. CONCLUSION: There is the need to monitor, screen and provide appropriate strategies such as through the promotion of healthy lifestyles to prevent the development of comorbidities in young people with Down syndrome and, where present, to reduce their impact.

NextGen Flight Deck Surface Trajectory-Based Operations (STBO): Contingency Holds

Science.gov (United States)

Bakowski, Deborah Lee; Hooey, Becky Lee; Foyle, David C.; Wolter, Cynthia A.; Cheng, Lara W. S.

2013-01-01

The purpose of this pilot-in-the-loop taxi simulation was to investigate a NextGen Surface Trajectory-Based Operations (STBO) concept called "contingency holds." The contingency-hold concept parses a taxi route into segments, allowing an air traffic control (ATC) surface traffic management (STM) system to hold an aircraft when necessary for safety. Under nominal conditions, if the intersection or active runway crossing is clear, the hold is removed, allowing the aircraft to continue taxiing without slowing, thus improving taxi efficiency, while minimizing the excessive brake use, fuel burn, and emissions associated with stop-and-go taxi. However, when a potential traffic conflict exists, the hold remains in place as a fail-safe mechanism. In this departure operations simulation, the taxi clearance included a required time of arrival (RTA) to a specified intersection. The flight deck was equipped with speed-guidance avionics to aid the pilot in safely meeting the RTA. On two trials, the contingency hold was not released, and pilots were required to stop. On two trials the contingency hold was released 15 sec prior to the RTA, and on two trials the contingency hold was released 30 sec prior to the RTA. When the hold remained in place, all pilots complied with the hold. Results also showed that when the hold was released at 15-sec or 30-sec prior to the RTA, the 30-sec release allowed pilots to maintain nominal taxi speed, thus supporting continuous traffic flow; whereas, the 15-sec release did not. The contingency-hold concept, with at least a 30-sec release, allows pilots to improve taxiing efficiency by reducing braking, slowing, and stopping, but still maintains safety in that no pilots "busted" the clearance holds. Overall, the evidence suggests that the contingency-hold concept is a viable concept for optimizing efficiency while maintaining safety.

2017-11-01

Improvements in care and treatment have led to more young adults with life-limiting conditions living beyond childhood, which means they must make the transition from children's to adult services. This has proved a challenging process for both young adults and service providers, with complex transition interventions interacting in unpredictable ways with local contexts. To explain how intervention processes interact with contextual factors to help transition from children's to adult services for young adults with life-limiting conditions. Systematic realist review of the literature. Literature was sourced from four electronic databases: Embase, MEDLINE, Science Direct and Cochrane Library from January 1995 to April 2016. This was supplemented with a search in Google Scholar and articles sourced from reference lists of included papers. Data were extracted using an adapted standardised data extraction tool which included identifying information related to interventions, mechanisms, contextual influences and outcomes. Two reviewers assessed the relevance of papers based on the inclusion criteria. Methodological rigor was assessed using the relevant Critical Appraisal Skills Programme tools. 78 articles were included in the review. Six interventions were identified related to an effective transition to adult services. Contextual factors include the need for children's service providers to collaborate with adult service providers to prepare an environment with knowledgeable staff and adequate resources. Mechanisms triggered by the interventions include a sense of empowerment and agency amongst all stakeholders. Early planning, collaboration between children's and adult service providers, and a focus on increasing the young adults' confidence in decision-making and engaging with adult services, are vital to a successful transition. Interventions should be tailored to their context and focused not only on organisational procedures but on equipping young adults, parents

To explore socioeconomic and lifestyle factors associated with the prevalence of self-reported chronic conditions among older adults in Ecuador. The sample was drawn from the nationally representative observational cross-sectional data of the Health, Well-Being, and Aging survey conducted in Ecuador in 2009. Logistic regression models were used to explore the association between socioeconomic and lifestyle factors and the prevalence of selected chronic conditions. Older women in Ecuador are more likely than men to have been previously diagnosed with diabetes, heart disease, high blood pressure, and arthritis. Results suggest no difference by education or health insurance on number and type of self-reported chronic conditions. However, older adults who resided in the coastal area were more likely to report having diabetes, heart disease, high blood pressure, and stroke than those in the highlands. Living in rural areas was associated with lower odds of having diabetes and high blood pressure. Compared to white older adults, indigenous older adults were less likely to report having high blood pressure, but more likely to report having arthritis. Older age in Ecuador is marked by low educational levels and poverty. Female gender and living in coastal areas were associated with higher risks of self-reported chronic conditions.

Full Text Available Introduction. In the last decades, life expectancy of persons with Down syndrome (DS has dramatically increased and it is estimated that they will be living as long as the general population within a generation. Despite being included among the progeroid syndromes, because of the presence of features typically observed in older adults, DS is still regarded as a disease of pediatric interest. Because limited knowledge is available on the clinical characteristics of adults with DS, this study aimed to assess clinical and non-clinical features of this population and to describe similarities to the geriatric population. Methods. In this study, we described 60 adults with DS evaluated at the Day Hospital of the Geriatric Department of the Policlinico A. Gemelli, Università Cattolica del Sacro Cuore in Rome. Individuals were assessed through a standardized protocol. Results. The mean age of study participants was 38 years (range, 18 to 58 years and 42 (70.0% were women. Geriatric conditions were highly prevalent: severe cognitive impairment was diagnosed in 39 (65.0% participants, behavioral symptoms were present in 25 (41.7% and functional impairment in 23 (38.3%. Six (10.0% participants lived in institutions and 11 (18.3% were diagnosed as obese. The mean number of drugs used was 2.4; use of psychotropic drugs was highly prevalent. The most common chronic diseases were thyroid problems (44, 73.3%, followed by mood disorders (19, 31.7%, osteoporosis (18, 30.0% and cardiac problems (10, 16.7%. Geriatric conditions and chronic diseases were more prevalent among participants aged ≥40 years. Conclusions. Several similarities between older adults and adults with DS were observed. Comorbidities, geriatric conditions, cognitive and functional deficits and social problems are highly prevalent in both populations, contributing to the high complexity of these patients’ assessment and treatment.

This study investigated developmental differences in aversive conditioning, extinction, and reinstatement (i.e., the recovery of conditioned aversive associations following reexposure to the unconditioned stimulus [US] post-extinction). This study examined these mechanisms in children (M age =8.8years), adolescents (M age =16.1years), and adults (M age =32.3years) using differential aversive conditioning with a geometric shape conditional stimulus (CS+) paired with an aversive sound US and another shape (CS-) presented alone. Following an extinction phase in which both CSs were presented alone, half of the participants in each age group received three US exposures (reinstatement condition) and the other half did not (control condition), followed by all participants completing an extinction retest phase on the same day. Findings indicated (a) significant differences in generalizing aversive expectancies to safe stimuli during conditioning and extinction that persisted during retest in children relative to adults and adolescents, (b) significantly less positive CS reevaluations during extinction that persisted during retest in adolescents relative to adults and children, and (c) reinstatement of US expectancies to the CS+ relative to the CS- in all age groups. Results suggest important differences in stimulus safety learning in children and stimulus valence reevaluation in adolescents relative to adults. Copyright © 2017 Elsevier Inc. All rights reserved.

Measuring vascular reactivity with resting-state blood oxygenation level-dependent (BOLD) signal fluctuations: A potential alternative to the breath-holding challenge?

Measurement of the ability of blood vessels to dilate and constrict, known as vascular reactivity, is often performed with breath-holding tasks that transiently raise arterial blood carbon dioxide (P a CO 2 ) levels. However, following the proper commands for a breath-holding experiment may be difficult or impossible for many patients. In this study, we evaluated two approaches for obtaining vascular reactivity information using blood oxygenation level-dependent signal fluctuations obtained from resting-state functional magnetic resonance imaging data: physiological fluctuation regression and coefficient of variation of the resting-state functional magnetic resonance imaging signal. We studied a cohort of 28 older adults (69 ± 7 years) and found that six of them (21%) could not perform the breath-holding protocol, based on an objective comparison with an idealized respiratory waveform. In the subjects that could comply, we found a strong linear correlation between data extracted from spontaneous resting-state functional magnetic resonance imaging signal fluctuations and the blood oxygenation level-dependent percentage signal change during breath-holding challenge ( R 2  = 0.57 and 0.61 for resting-state physiological fluctuation regression and resting-state coefficient of variation methods, respectively). This technique may eliminate the need for subject cooperation, thus allowing the evaluation of vascular reactivity in a wider range of clinical and research conditions in which it may otherwise be impractical.

Self-Verification Strivings in Children Holding Negative Self-Views: The Mitigating Effects of a Preceding Success Experience.

Research among adults has consistently shown that people holding negative self-views prefer negative over positive feedback. The present study tested the hypothesis that this preference is less robust among pre-adolescents, such that it will be mitigated by a preceding positive event. Pre-adolescents (n = 75) holding positive or negative global self-esteem were randomized to a favorable or unfavorable peer evaluation outcome. Next, preferences for positive versus negative feedback were assessed using an unobtrusive behavioral viewing time measure. As expected, results showed that after being faced with the success outcome children holding negative self-views were as likely as their peers holding positive self-views to display a significant preference for positive feedback. In contrast, children holding negative self-views displayed a stronger preference for negative feedback after being faced with the unfavorable outcome that matched their pre-existing self-views.

Many components and structures of nuclear power plants are exposed to the water chemistry conditions during the operation. Recently, as design life of nuclear power plant is expanded over 60 years, the environmentally assisted fatigue (EAF) due to these water chemistry conditions has been considered as one of the important damage mechanisms of the safety class 1 components. Therefore, many studies to evaluate the effect of light water reactor (LWR) coolant environments on fatigue life of materials have been conducted. Many EAF test results including Argonne National Laboratory’s consistently indicated the substantial reduction of fatigue life in the light water reactor environments. However, there is a discrepancy between laboratory test data and plant operating experience regarding the effects of environment on fatigue: while laboratory test data suggest huge accumulation of fatigue damage, very limited experience of cracking caused by the low cycle fatigue in light water reactor. These hold-time effect tests are preformed to characterize the effects of strain holding on the fatigue life of austenitic stainless steels in PWR environments in comparison with the existing fixed strain rate results. Low cycle fatigue life tests were conducted for the type 316 stainless steel in 310℃ air and PWR environments with triangular strain. In agreement with the previous reports, the LCF life was reduced in PWR environments. Also for the slower strain rate, the reduction of LCF life was greater than the faster strain rate. The LCF test conditions for the hold-time effects were determined by the references and consideration of actual plant transient. To simulate the heat-up and cooldown transient, sub-peak strain holding during the down-hill of strain amplitude was chosen instead of peak strain holding which used in the previous researches.

Frequency interpretation of hold-time experiments on high temperature low-cycle fatigue of steels for LMFBR

1975-01-01

The effect of frequency or hold-time on the low-cycle fatigue strength of AISI 316 stainless steel and SCM 3 Cr--Mo steel for fuel cladding, piping, and other structural members of LMFBR is investigated under high temperature conditions. Push-pull fatigue tests are conducted in air under conditions of fully reversed axial strain-control with a tensile strain hold-time ranging fromm 0 to 120 min for AISI 316, and with a tensile and an equal compressive strain hold-time ranging from 0 to 995 s for SCM 3. In these tests, a decrease of fatigue life is observed as the hold-time is increased. An empirical formula is presented which can predict well the effect of hold-time on high temperature low-cycle fatigue life in terms of frequency. The formula is a little different from those in the literature

Leisure as a resource for successful aging by older adults with chronic health conditions.

Hutchinson, Susan L; Nimrod, Galit

2012-01-01

Drawing on the model of Selective Optimization with Compensation (SOC) (Baltes & Baltes, 1990), the purpose of this article is to examine leisure-related goals of older adults with chronic conditions and the strategies they use to not only successfully manage their chronic health conditions but live well with them. Semi-structured in-person interviews were conducted with 18 community-dwelling older adults (nine males, nine females, ages 58-87 years) with a variety of chronic conditions. Inductive and deductive within and cross-case thematic analyses resulted in descriptions of changes and continuity in participants' leisure participation following the onset of their chronic condition and construction of four themes: drawing on existing resources for continued involvement, setting leisure-based goals, using strategies to get more out of life, and more than managing: living a life of meaning. Implications for promoting successful aging are discussed, specifically the benefits of incorporating information and skill-building to help older adults recognize that leisure can be a resource for healthy aging and self-managing their chronic health condition.

Amygdala dysfunction is theorized to give rise to poor fear conditioning, which in turn predisposes to crime, but it is not known whether poor conditioning precedes criminal offending. This study prospectively assessed whether poor fear conditioning early in life predisposes to adult crime in a large cohort. Electrodermal fear conditioning was assessed in a cohort of 1,795 children at age 3, and registration for criminal offending was ascertained at age 23. In a case-control design, 137 cohort members with a criminal record were matched on gender, ethnicity, and social adversity with 274 noncriminal comparison members. Statistical analyses compared childhood fear conditioning for the two groups. Criminal offenders showed significantly reduced electrodermal fear conditioning at age 3 compared to matched comparison subjects. Poor fear conditioning at age 3 predisposes to crime at age 23. Poor fear conditioning early in life implicates amygdala and ventral prefrontal cortex dysfunction and a lack of fear of socializing punishments in children who grow up to become criminals. These findings are consistent with a neurodevelopmental contribution to crime causation.

Xerostomia is a subjective symptom of dryness in the mouth. Although a correlation between xerostomia and oral conditions in the elderly has been reported, there are few such studies in the young adults. The aim of this study was to examine the relationship of xerostomia with the gingival condition in university students. A total of 2077 students (1202 male subjects and 875 female subjects), 18-24 years of age, were examined. The disease activity and severity of the gingival condition were assessed as the percentage of teeth with bleeding on probing (%BOP) and the presence of teeth with probing pocket depth of ≥ 4 mm, respectively. Additional information on xerostomia, oral health behaviors, coffee/tea intake and nasal congestion was collected via a questionnaire. Path analysis was used to test pathways from xerostomia to the gingival condition. One-hundred and eighty-three (8.8%) students responded that their mouths frequently or always felt dry. Xerostomia was related to %BOP and dental plaque formation, but was not related to the presence of probing pocket depth ≥ 4 mm. In the structural model, xerostomia was related to dental plaque formation (p Xerostomia was associated with coffee/tea intake (p Xerostomia was indirectly related to gingival disease activity through the accumulation of dental plaque. Nasal congestion and coffee/tea intake also affected xerostomia.

A review of health utilities across conditions common in paediatric and adult populations

Directory of Open Access Journals (Sweden)

Hopkins Robert B

2010-01-01

Full Text Available Abstract Background Cost-utility analyses are commonly used in economic evaluations of interventions or conditions that have an impact on health-related quality of life. However, evaluating utilities in children presents several challenges since young children may not have the cognitive ability to complete measurement tasks and thus utility values must be estimated by proxy assessors. Another solution is to use utilities derived from an adult population. To better inform the future conduct of cost-utility analyses in paediatric populations, we reviewed the published literature reporting utilities among children and adults across selected conditions common to paediatric and adult populations. Methods An electronic search of Ovid MEDLINE, EMBASE, and the Cochrane Library up to November 2008 was conducted to identify studies presenting utility values derived from the Health Utilities Index (HUI or EuroQoL-5Dimensions (EQ-5D questionnaires or using time trade off (TTO or standard gamble (SG techniques in children and/or adult populations from randomized controlled trials, comparative or non-comparative observational studies, or cross-sectional studies. The search was targeted to four chronic diseases/conditions common to both children and adults and known to have a negative impact on health-related quality of life (HRQoL. Results After screening 951 citations identified from the literature search, 77 unique studies included in our review evaluated utilities in patients with asthma (n = 25, cancer (n = 23, diabetes mellitus (n = 11, skin diseases (n = 19 or chronic diseases (n = 2, with some studies evaluating multiple conditions. Utility values were estimated using HUI (n = 33, EQ-5D (n = 26, TTO (n = 12, and SG (n = 14, with some studies applying more than one technique to estimate utility values. 21% of studies evaluated utilities in children, of those the majority being in the area of oncology.

To examine the association between mental illness and chronic physical conditions in older adults and investigate whether co-occurring substance use disorders (SUDs) are associated with greater risk of chronic physical conditions beyond mental illness alone. A retrospective cross-sectional study. Medicare and Medicaid programs in Massachusetts. Massachusetts Medicare and Medicaid members aged 65 and older as of January 1, 2005 (N = 679,182). Diagnoses recorded on Medicare and Medicaid claims were used to identify mental illness, SUDs, and 15 selected chronic physical conditions. Community-dwelling older adults with mental illness or SUDs had higher adjusted risk for 14 of the 15 selected chronic physical conditions than those without these disorders; the only exception was eye diseases. Moreover, those with co-occurring SUDs and mental illness had the highest adjusted risk for 11 of these chronic conditions. For residents of long-term care facilities, mental illness and SUDs were only moderately associated with the risk of chronic physical conditions. Community-dwelling older adults with mental illness or SUDs, particularly when they co-occurred, had substantially greater medical comorbidity than those without these disorders. For residents of long-term care facilities, the generally uniformly high medical comorbidity may have moderated this relationship, although their high prevalence of mental illness and SUDs signified greater healthcare needs. These findings strongly suggest the imminent need for integrating general medical care, mental health services, and addiction health services for older adults with mental illness or SUDs. © 2011, Copyright the Authors Journal compilation © 2011, The American Geriatrics Society.

Most research on human fear conditioning and its generalization has focused on adults whereas only little is known about these processes in children. Direct comparisons between child and adult populations are needed to determine developmental risk markers of fear and anxiety. We compared 267 children and 285 adults in a differential fear conditioning paradigm and generalization test. Skin conductance responses (SCR) and ratings of valence and arousal were obtained to indicate fear learning. Both groups displayed robust and similar differential conditioning on subjective and physiological levels. However, children showed heightened fear generalization compared to adults as indexed by higher arousal ratings and SCR to the generalization stimuli. Results indicate overgeneralization of conditioned fear as a developmental correlate of fear learning. The developmental change from a shallow to a steeper generalization gradient is likely related to the maturation of brain structures that modulate efficient discrimination between danger and (ambiguous) safety cues. © 2016 The Authors.

Languages exhibit sociolinguistic variation, such that adult native speakers condition the usage of linguistic variants on social context, gender, and ethnicity, among other cues. While the existence of this kind of socially conditioned variation is well-established, less is known about how it is acquired. Studies of naturalistic language use by children provide various examples where children's production of sociolinguistic variants appears to be conditioned on similar factors to adults' production, but it is difficult to determine whether this reflects knowledge of sociolinguistic conditioning or systematic differences in the input to children from different social groups. Furthermore, artificial language learning experiments have shown that children have a tendency to eliminate variation, a process which could potentially work against their acquisition of sociolinguistic variation. The current study used a semi-artificial language learning paradigm to investigate learning of the sociolinguistic cue of speaker identity in 6-year-olds and adults. Participants were trained and tested on an artificial language where nouns were obligatorily followed by one of two meaningless particles and were produced by one of two speakers (one male, one female). Particle usage was conditioned deterministically on speaker identity (Experiment 1), probabilistically (Experiment 2), or not at all (Experiment 3). Participants were given tests of production and comprehension. In Experiments 1 and 2, both children and adults successfully acquired the speaker identity cue, although the effect was stronger for adults and in Experiment 1. In addition, in all three experiments, there was evidence of regularization in participants' productions, although the type of regularization differed with age: children showed regularization by boosting the frequency of one particle at the expense of the other, while adults regularized by conditioning particle usage on lexical items.

To assess the stability and reproducibility of different breath-hold levels in healthy volunteers and patients using dynamic MRI (dMRI). In ten healthy volunteers and ten patients with pulmonary hypertension (PH) and normal lung function craniocaudal intrathoracic distances (CCD) were measured during inspiratory and expiratory breath-hold (15 s) (in healthy volunteers additionally at a self-chosen mid-inspiratory breath-hold) using dMRI (trueFISP, three images/s). To evaluate stability and intraobserver reproducibility of the different breath-hold levels, CCDs, time-distance curves, confidence intervals (CIs), Mann-Witney U test and regression equations were calculated. In healthy volunteers there was a substantial decrease of the CCD during the inspiratory breath-hold in contrast to the expiratory breath-hold. The CI at inspiration was 2.84{+-}1.28 in the right and 2.1{+-}0.68 in the left hemithorax. At expiration the CI was 2.54{+-}1.18 and 2.8{+-}1.48. Patients were significantly less able to hold their breath at inspiration than controls (P<0.05). In patients CI was 4.53{+-}4.06 and 3.46{+-}2.21 at inspiration and 4.45{+-}4.23 and 4.76{+-}3.73 at expiration. Intraobserver variability showed no significant differences either in patients or in healthy subjects. Reproducibility was significantly lower at a self-chosen breath-hold level of the healthy volunteers. DMRI is able to differentiate stability and reproducibility of different breath-hold levels. Expiratory breath-hold proved to be more stable than inspiratory breath-hold in healthy volunteers and patients. (orig.)

In-process hold-up as a measure of safeguards significance

International Nuclear Information System (INIS)

Hamlin, A.G.

1983-01-01

This paper examines the use of the in-process hold-up itself, as a measure of safeguards significance. It is argued that for any process plant it is possible to define design limits for in-process hold-up, outside which the plant will not operate, or will operate in a detectably abnormal manner. It follows, therefore, that if the in-process hold-up can be derived at frequent intervals by input/output analysis from the start of the campaign, the only diversion that can be made from it during that campaign is limited to the quantity necessary to move the apparent in-process hold-up from its normal operating condition to the upper limiting condition. It also follows that detection of this diversion is as positive for protracted diversion as for abrupt diversion. If that part of the in-process inventory that is only measurable by input/output analysis has an upper operating limit that differs from its normal operating limit by less than a significant safeguards quantity of the material in question, the IAEA's criteria for both quantity and timeliness can be met by a combination of input/output analysis to determine in-process hold-up during the campaign, together with a material balance over the campaign. The paper examines the possibility of applying this measure to process plants in general, discusses means of minimizing the in-process inventory that must be determined by input/output analysis, and the performance required of the input and output analysis. It concludes that with current precision of measurement and with one input and one output batch per day, each measured, the method would be satisfactory for a campaign lasting nearly a year and involving 6 tonnes of plutonium. The paper examines the considerable advantages in verification that would arise from limiting safeguards analyses to the two points of input and output. (author)

In vitro holding and PLD-repair. Pt. 2

The repair of potentially lethal damage (PLDR) in mammalian cells is expected to be better in quiescent cultures since PLD is supposedly fixed during cycle progression. Plateau phase cultures, therefore, serve as models because of assumed mitotic quiescence. Four established cell lines (V79, CHO, L5178Y and HELA) and one euploid cell strain IMR-90 have been analysed by flow cytometry and electron microscopy to address questions on quiescence in the plateau phase and the effect of holding (induction of quiescence by nutrient privation). In contrast to commonly held views, our results indicate that the quiescent fraction in cultures from transformed cells is exceedingly low (1% or less). Plateau phase cultures of transformed cells are constantly turning over. Euploid cells like the IMR-90 show true quiescence in the plateau phase. Holding causes typical cytopathological changes. These changes have been ultrastructurely characterised. Resistant sub-populations of cells can be selected out under holding-conditions. Such selected cells show completely different radiobiological characteristics, which raise questions on the interpretation of data on PLDR. (orig.)

Cognitive-motor interference while grasping, lifting and holding objects.

Full Text Available In daily life, object manipulation is usually performed concurrently to the execution of cognitive tasks. The aim of the present study was to determine which aspects of precision grip require cognitive resources using a motor-cognitive dual-task paradigm. Eighteen healthy participants took part in the experiment, which comprised two conditions. In the first condition, participants performed a motor task without any concomitant cognitive task. They were instructed to grip, lift and hold an apparatus incorporating strain gauges allowing a continuous measurement of the force perpendicular to each contact surface (grip force, GF as well as the total tangential force applied on the object (load force, LF. In the second condition, participants performed the same motor task while concurrently performing a cognitive task consisting in a complex visual search combined with counting. In the dual-task condition, we found a significant increase in the duration of the preload phase (time between initial contact of the fingers with the apparatus and onset of the load force, as well as a significant increase of the grip force during the holding phase, indicating that the cognitive task interfered with the initial force scaling performed during the preload phase and the fine-tuning of grip force during the hold phase. These findings indicate that these aspects of precision grip require cognitive resources. In contrast, other aspects of the precision grip, such as the temporal coupling between grip and load forces, were not affected by the cognitive task, suggesting that they reflect more automatic processes. Taken together, our results suggest that assessing the dynamic and temporal parameters of precision grip in the context of a concurrent cognitive task may constitute a more ecological and better-suited tool to characterize motor dysfunction in patients.

2018-01-01

Walking is being promoted for health and transportation purposes across all climatic regions in the US and beyond. Despite this, an uncomfortable microclimate condition along sidewalks is one of the major deterrents of walking, and more empirical research is needed to determine the risks of heat exposure to pedestrians while walking. This study examined the effect of street trees and grass along sidewalks on air temperatures. A series of thermal images were taken at the average heights of adults and children in the US to objectively measure the air temperatures of 10 sidewalk segments in College Station, TX, USA. After controlling the other key physical environmental conditions, sidewalks with more trees or wider grass buffer areas had lower air temperatures than those with less vegetation. Children were exposed to higher temperatures due to the greater exposure or proximity to the pavement surface, which tends to have higher radiant heat. Multivariate regression analysis suggested that the configuration of trees and grass buffers along the sidewalks helped to promote pleasant thermal conditions and reduced the differences in ambient air temperatures measured at child and adult heights. This study suggests that street trees and vegetated ground help reduce the air temperatures, leading to more thermally comfortable environments for both child and adult pedestrians in warm climates. The thermal implications of street landscape require further attention by researchers and policy makers that are interested in promoting outdoor walking. PMID:29346312

The Mental Health of Older LGBT Adults.

Yarns, Brandon C; Abrams, Janet M; Meeks, Thomas W; Sewell, Daniel D

2016-06-01

There are approximately one million older lesbian, gay, bisexual, and transgender (LGBT) adults in the USA. Their mental health issues result from interactions between genetic factors and stress associated with membership in a sexual minority group. Although advancements in acceptance and equal treatment of LGBT individuals have been occurring, sexual minority status remains associated with risks to physical and mental well-being. Older LGBT adults are more likely to have experienced mistreatment and discrimination due to living a majority of their lives prior to recent advancements in acceptance and equal treatment. All LGBT adults experience one common developmental challenge: deciding if, when, and how to reveal to others their gender identity and/or sexual orientation. LGBT individuals have higher rates of anxiety, depression, and substance use disorders and also are at increased risk for certain medical conditions like obesity, breast cancer, and human immunodeficiency virus (HIV). Improved education and training of clinicians, coupled with clinical research efforts, holds the promise of improved overall health and life quality for older LGBT adults.

A frequency interpretation of hold-time experiments on high temperature low-cycle fatigue of steels for LMFBR

Udoguchi, T.; Asada, Y.; Ichino, I.

1975-01-01

The effect of frequency or hold-time on the low-cycle fatigue strength of AISI 316 stainless steel and SCM 3 Cr-Mo steel for fuel cladding, piping and other structural members of LMFBR is investigated under high temperature conditions. Push-pull fatigue tests are conducted in air under conditions of fully reversed axial strain-control with a tensile strain hold-time ranging from 0 to 120 min for AISI 316, and with a tensile and an equal compressive strain hold-time ranging from 0 to 995 s for SCM 3. In these tests, a considerable decrease of fatigue life is observed as the hold-time is increased. An empirical formula is presented which can predict well the effect of hold-time on high temperature low-cycle fatigue life in terms of frequency. The formula is a little different from those in the literature. (author)

Task-set switching under cue-based versus memory-based switching conditions in younger and older adults.

Kray, Jutta

2006-08-11

Adult age differences in task switching and advance preparation were examined by comparing cue-based and memory-based switching conditions. Task switching was assessed by determining two types of costs that occur at the general (mixing costs) and specific (switching costs) level of switching. Advance preparation was investigated by varying the time interval until the next task (short, middle, very long). Results indicated that the implementation of task sets was different for cue-based switching with random task sequences and memory-based switching with predictable task sequences. Switching costs were strongly reduced under cue-based switching conditions, indicating that task-set cues facilitate the retrieval of the next task. Age differences were found for mixing costs and for switching costs only under cue-based conditions in which older adults showed smaller switching costs than younger adults. It is suggested that older adults adopt a less extreme bias between two tasks than younger adults in situations associated with uncertainty. For cue-based switching with random task sequences, older adults are less engaged in a complete reconfiguration of task sets because of the probability of a further task change. Furthermore, the reduction of switching costs was more pronounced for cue- than memory-based switching for short preparation intervals, whereas the reduction of switch costs was more pronounced for memory- than cue-based switching for longer preparation intervals at least for older adults. Together these findings suggest that the implementation of task sets is functionally different for the two types of task-switching conditions.

Full Text Available In the present article, an attempt was made to assess the sustainability of agricultural holdings with diff erent directions of production. Agricultural holdings in the Podlaskie voivodeship registered in the FADN system in 2011–2012 were investigated. Assessment accounted for agroecological indicators (share of permanent grasslands, share of cereals in crops, soil coverage with vegetation, stock density and economic indicators (profi tableness of land and labor. Analysis was conducted according to a classifi cation into agricultural holding types: fi eldcrops, dairy cattle, and granivores. Fieldcrop and granivore holdings achieved more favourable environmental sustainability indicators. Holdings specializing in dairy cattle breeding posed a threat to the natural environment, mainly due to their excessive stock density. Economic sustainability assessment showed that granivore holdings were assessed most favorably. In these holdings, holding income per full-time worker was 37% greater than in fi eldcrop holdings and 57% greater than in dairy cattle holdings.

Making prudent recommendations for return-to-play in adult athletes with cardiac conditions.

Oliveira, Leonardo P J; Lawless, Christine E

2011-01-01

Clinicians who treat millions of adult athletes throughout the world may be faced with participation or return-to-play decisions in individuals with known or suspected cardiac conditions. Here we review existing published participation guidelines and analyze emerging data from ongoing registries and population-based studies pertaining to return-to-play decisions for cardiac conditions specifically affecting adult athletes. Considerations related to return-to-play decisions will vary according to age of the athlete, with inherited disorders being the main consideration in younger adult athletes aged 18 to 40 yr, and coronary artery disease being the main consideration in older adult athletes aged 40 yr and older. Although this arbitrary division is based on the epidemiology of underlying heart disease in these populations, the essential return-to-play decision process for both age groups is quite similar. Among the most widely used guidelines to make return-to-play decisions in this group of athletes are the 36th Bethesda Conference Eligibility Recommendations for Competitive Athletes with Cardiovascular Abnormalities. These have long been considered the "gold standard" for determining return-to-play decisions in young athletes in the United States. Other guidelines are available for unique purposes, including The European Society of Cardiology guidelines, and the American Heart Association published recommendations regarding participation of young patients (younger than 40 yr) with genetic cardiovascular diseases in recreational sports. The latter are consistent with the 36th Bethesda guidelines and cover common genetically based diseases such as inherited cardiomyopathies, channelopathy, and connective tissue disorders like Marfan's syndrome. The consensus on masters athletes (older than 40 yr) provides return-to-play decisions for a wide variety of conditioned states, from elite older athletes to walk-up athletes.

Inflation, operating cycle, and cash holdings

Directory of Open Access Journals (Sweden)

Yanchao Wang

2014-12-01

Full Text Available A corporate cash-holding strategy is a trade-off between the costs and benefits of holding cash. At the macrolevel, firms are inclined to adjust and optimize their cash-holding strategies in response to changes in purchasing power due to inflation. At the microlevel, the operating cycle, which indicates the speed and turnover of corporate cash flow, also influences the corporate cash-holding strategy. Firms flexibly adjust their cash-holding strategies in response to changes in the internal and external environment, which is referred to as the cash adjustment strategy. We examine these predicted relationships using a sample of listed firms in China’s stock market over the 1998–2009 period. Consistent with our predictions, the empirical results indicate a significant negative association between cash holdings and the CPI, but the relationship is reversed when the CPI reaches a certain level. There is also a U-shaped relationship between operating cycle and cash holdings, and this relationship is similarly influenced by changes in the inflation level. In examining the macroeconomic environment and microlevel firm-specific characteristics simultaneously, our findings supplement the literature on firms’ cash-holding strategies and provide theoretical and practical implications.

The effects of breath-holding on pulmonary regurgitation measured by cardiovascular magnetic resonance velocity mapping

Directory of Open Access Journals (Sweden)

Babu-Narayan Sonya V

2009-01-01

Full Text Available Abstract Background Pulmonary regurgitation is a common and clinically important residual lesion after repair of tetralogy of Fallot. Cardiovascular magnetic resonance (CMR phase contrast velocity mapping is widely used for measurement of pulmonary regurgitant fraction. Breath-hold acquisitions, usually acquired during held expiration, are more convenient than the non-breath-hold approach, but we hypothesized that breath-holding might affect the amount of pulmonary regurgitation. Methods Forty-three adult patients with a previous repair of tetralogy of Fallot and residual pulmonary regurgitation were investigated with CMR. In each, pulmonary regurgitant fraction was measured from velocity maps transecting the pulmonary trunk, acquired during held expiration, held inspiration, by non-breath-hold acquisition, and also from the difference of right and left ventricular stroke volume measurements. Results Pulmonary regurgitant fraction was lower when measured by velocity mapping in held expiration compared with held inspiration, non-breath-hold or stroke volume difference (30.8 vs. 37.0, 35.6, 35.4%, p = 0.00017, 0.0035, 0.026. The regurgitant volume was lower in held expiration than in held inspiration (41.9 vs. 48.3, p = 0.0018. Pulmonary forward flow volume was larger during held expiration than during non-breath-hold (132 vs. 124 ml, p = 0.0024. Conclusion Pulmonary regurgitant fraction was significantly lower in held expiration compared with held inspiration, free breathing and stroke volume difference. Altered airway pressure could be a contributory factor. This information is relevant if breath-hold acquisition is to be substituted for non-breath-hold in the investigation of patients with a view to re-intervention.

This study aims to: (1) test whether the minority stressors disclosure of sexual orientation; and (2) internalized heterosexism are predictive of chronic physical health conditions; and (3) depression; (4) to test direct and indirect relationships between these variables; and (5) whether chronic physical health conditions are further predictive of depression, net of disclosure of sexual orientation and internalized heterosexism. Secondary analysis of national, community-based surveys of 2349 lesbian, gay, and bisexual adults aged 50 and older residing in the US utilizing structural equation modeling. Congruent with minority stress theory, disclosure of sexual orientation is indirectly associated with chronic physical health conditions and depression, mediated by internalized heterosexism with a suppressor effect. Internalized heterosexism is directly associated with chronic physical health conditions and depression, and further indirectly associated with depression mediated by chronic physical health conditions. Finally, chronic physical health conditions have an additional direct relationship with depression, net of other predictor variables. Minority stressors and chronic physical health conditions independently and collectively predict depression, possibly a synergistic effect. Implications for depression among older sexual minority adults are discussed.

Adults with mental health conditions commonly experience difficulties with emotion regulation which affect their social functioning. Arts-based groups provide opportunities for shared emotional experiences and emotion regulation. This study explores emotion regulation strategies and the emotional effects of arts-based group participation in adults with mental health problems and in controls. The 62 participants included 39 adults with chronic mental health problems who were members of arts-based groups (ABG) and 23 comparison choir (CC) members who were not specifically experiencing mental health problems. The repeated measures design included self-reports of emotion upon waking (T1), the hour before group (T2), end of the group (T3), and evening (T4), as well as participant notes to explain their emotion ratings at each time. They also completed measures of individual and interpersonal emotion regulation. The ABG participants engaged marginally more in affect worsening strategies than CC (p = .057 and .08), but there were no other group differences. All participants reported a significant increase in positive emotions, F (3, 180) = 28.044, p emotions during the arts-based activity: F (2.637, 155.597) = 21.09, p emotions was short-lived, while the effect on negative emotions lasted until evening. Findings show that participation in arts-based groups benefits the emotions of both healthy adults and those experiencing mental health conditions through individual and interpersonal processes. Individuals with chronic mental health conditions often experience difficulties in emotion processing Participation in arts-based groups was associated with significant increases in positive emotions although these were short-lived Negative emotion was significantly decreased during arts-based group activities, and sustained to the evening assessment Adults with chronic mental health conditions were equally able to derive emotional benefits as healthy adults. © 2017 The

2013-07-01

Objective : Adults with craniofacial conditions experience more psychosocial problems than adults in the general population, but little is known about the factors that render a person more or less susceptible to these problems. Guided by research on adults with other conditions that affect appearance, this study examined predictors of psychosocial outcome in adults with craniofacial conditions. Design : Single-sample cross-sectional design. Setting : The Australian Craniofacial Unit, Women's and Children's Hospital, Adelaide, one of the main craniofacial treatment centers in Australia. Participants : Adults (N  =  93; 36.9% of the potential sample) with congenital craniofacial conditions (excluding cleft lip and/or cleft palate) who were treated in the Australian Craniofacial Unit. Main Outcome Measures : All participants completed measures assessing anxiety, depression, and quality of life (Hospital Anxiety and Depression Scale, Short-Form Health Survey) and variables predicted to affect these outcomes (SF-36 Health Survey - Multidimensional Scale of Perceived Social Support, Rosenberg Self-Esteem Scale, Cleft Satisfaction Profile, Brief Fear of Negative Evaluation Scale, Derriford Appearance Scale). Results : Multiple regression analyses revealed that anxiety was predicted by social support, self-esteem, and fear of negative evaluation, while depression was predicted by self-esteem and social support. Physical quality of life was not predicted by any of the measures. Satisfaction with appearance, gender, age, and education were not related to outcome. Conclusions : Interventions designed to increase perceived social support and self-esteem and reduce fear of negative evaluation appear to be indicated and may assist in establishing a causal relationship between these variables.

1994-12-01

The relationships between selected condition characteristics and self-esteem were investigated in a randomly drawn, community-based sample of 286 young adults with chronic illnesses and disabilities. Whether appraisals of the impact of the condition mediated relationships between condition characteristics and self-esteem, as measured by the Rosenberg Self-Esteem Scale, was also measured. As a group, the youth in this sample reported positive self-esteem. When sociodemographic and condition-related variables were considered simultaneously, maternal education, unpredictability of symptoms, prognosis, sensory impairment, and the presence of a co-occurring learning disability were found to have direct effects on esteem. Perceived impact mediated the relationship between condition characteristics and self-esteem. The results are discussed in relation to the role of impact appraisal in determining the emotional well-being of young adults with chronic illnesses.

A tube holding rig is described for the lateral support of tubes arranged in tight parcels in a heat exchanger. This tube holding rig includes not less than two tube supporting assemblies, with a space between them, located crosswise with respect to the tubes, each supporting assembly comprising a first set of parallel components in contact with the tubes, whilst a second set of components is also in contact with the tubes. These two sets of parts together define apertures through which the tubes pass [fr

Little is known about how combinations of chronic conditions in adults affect total health care expenditures. Our objective was to estimate the annual average total expenditures and out-of-pocket spending burden among US adults by combinations of conditions. We conducted a cross-sectional study using 2009 and 2011 data from the Medical Expenditure Panel Survey. The sample consisted of 9,296 adults aged 21 years or older with at least 2 of the following 4 highly prevalent chronic conditions: arthritis, diabetes mellitus, heart disease, and hypertension. Unadjusted and adjusted regression techniques were used to examine the association between chronic condition combinations and log-transformed total expenditures. Logistic regressions were used to analyze the relationship between chronic condition combinations and high out-of-pocket spending burden. Among adults with chronic conditions, adults with all 4 conditions had the highest average total expenditures ($20,016), whereas adults with diabetes/hypertension had the lowest annual total expenditures ($7,116). In adjusted models, adults with diabetes/hypertension and hypertension/arthritis had lower health care expenditures than adults with diabetes/heart disease (P expenditures compared with those with diabetes and heart disease. However, the difference was only marginally significant (P = .04). Among adults with arthritis, diabetes, heart disease, and hypertension, total health care expenditures differed by type of chronic condition combinations. For individuals with multiple chronic conditions, such as heart disease and diabetes, new models of care management are needed to reduce the cost burden on the payers.

Acquired heart conditions in adults with congenital heart disease: a growing problem.

Science.gov (United States)

Tutarel, Oktay

2014-09-01

The number of adults with congenital heart disease is increasing due to the great achievements in the field of paediatric cardiology, congenital heart surgery and intensive care medicine over the last decades. Mortality has shifted away from the infant and childhood period towards adulthood. As congenital heart disease patients get older, a high prevalence of cardiovascular risk factors is encountered similar to the general population. Consequently, the contribution of acquired morbidities, especially acquired heart conditions to patient outcome, is becoming increasingly important. Therefore, to continue the success story of the last decades in the treatment of congenital heart disease and to further improve the outcome of these patients, more attention has to be given to the prevention, detection and adequate therapy of acquired heart conditions. The aim of this review is to give an overview about acquired heart conditions that may be encountered in adults with congenital heart disease. Published by the BMJ Publishing Group Limited.

Safely prolonging single breath-holds to >5 min in patients with cancer; feasibility and applications for radiotherapy

Science.gov (United States)

Green, Stuart; Stevens, Andrea M; Parveen, Sophia; Stephens, Rebecca; Clutton-Brock, Thomas H

2016-01-01

Objective: Multiple, short and deep inspiratory breath-holds with air of approximately 20 s are now used in radiotherapy to reduce the influence of ventilatory motion and damage to healthy tissue. There may be further clinical advantages in delivering each treatment session in only one single, prolonged breath-hold. We have previously developed techniques enabling healthy subjects to breath-hold for 7 min. Here, we demonstrate their successful application in patients with cancer. Methods: 15 patients aged 37–74 years undergoing radiotherapy for breast cancer were trained to breath-hold safely with pre-oxygenation and mechanically induced hypocapnia under simulated radiotherapy treatment conditions. Results: The mean breath-hold duration was 5.3 ± 0.2 min. At breakpoint, all patients were normocapnic and normoxic [mean end-tidal partial pressure of carbon dioxide was 36 ± 1 standard error millimetre of mercury, (mmHg) and mean oxygen saturation was 100 ± 0 standard error %]. None were distressed, nor had gasping, dizziness or disturbed breathing in the post-breath-hold period. Mean blood pressure had risen significantly from 125 ± 3 to 166 ± 4 mmHg at breakpoint (without heart rate falling), but normalized within approximately 20 s of the breakpoint. During breath-holding, the mean linear anteroposterior displacement slope of the L breast marker was radiotherapy treatment conditions for longer than the typical beam-on time of a single fraction. We discuss the important applications of this technique for radiotherapy. Advances in knowledge: We demonstrate for the first time a technique enabling patients with cancer to deliver safely a single prolonged breath-hold of >5 min (10 times longer than currently used in radiotherapy practice), under simulated radiotherapy treatment conditions.

Factors associated with young adults delaying and forgoing driving licenses: results from Britain.

Le Vine, Scott; Polak, John

2014-01-01

To identify the reasons that young adults (age 17-29) in Britain delay or forgo driving license acquisition. Using year 2010 British National Travel Survey microdata, we first analyze self-reported reasons (including their prioritisation) for not holding a full car driving license and then estimate a logistic regression model for license-holding to investigate additional factors, several of which extend from previous studies. This study also employs a novel segmentation approach to analyze the sets of reasons that individual young adults cite for not driving. These results show that, despite the lack of a graduated driving license system at present, many young adults indicate that issues associated with the driving license acquisition process are the main reason they do not hold a full driving license. About 3 in 10 young adults can be interpreted as not viewing driving as a priority, though half of those without a license are either learning to drive or are deterred principally by the cost of learning. We calculate that after their 17th birthday (the age of eligibility for a full driving license) young adults spend a mean of 1.7 years learning to drive. Young adults citing the costs of insurance or car purchase are likely to cite them as secondary rather than the main reason for not driving, whereas those citing physical/health difficulties are very likely to cite this as the main reason they do not drive. Two distinct groups of young people are identified that both indicate that costs deter them from driving-one group that is less well off financially and that indicates that costs alone are the primary deterrent and one that reports that other reasons also apply and is better off. Status as an international migrant was found to be an important factor, net of confounding variables, for identifying that a young adult in Britain does not hold a driving license. Further research is needed to understand the relative saliency of plausible causal mechanisms for this

Collective behaviors of book holding durations

Li, Ren-De; Guo, Qiang; Han, Jing-Ti; Liu, Jian-Guo

2016-10-01

Duration can directly reflect the collective reading behaviors of library user book holding. In this paper, by introducing the burstiness and memory coefficients, we empirically investigate the collective book holding behavior of three university libraries. The statistical results show that there are similar properties among the students with different backgrounds, presenting the burstiness = - 0.2 and memory = 0.5 for three datasets, which indicates that memory and random effects coexist in student book holding durations. In addition, we analyze the behavior patterns without duplicate durations by merging a series of books borrowed and returned at the same time. The results show the average burstiness B increases to -0.16 and memory M drops to 0.16 for three datasets, which indicates that both duplicate behavior and student's preference affect the memory effect. Furthermore, we present a model which assumes student's next book holding duration follows the previous one with probability p, and with probability 1 - p, the student would hold the book independently. The experimental results show that the presented model can reproduce the burstiness and memory effect of student book holding durations when p = 0.5 for empirical datasets and p = 0.2 for de-duplicate datasets, which indicate that the student's preferential holding behavior occurs with the probability p. This work helps in deeply understanding the regularity of duration-based human behaviors.

There is a paucity of research exploring how spouses to older adults with multiple chronic conditions make meaning of their caregiving experience. For this study, we asked: What is the experience of spousal caregivers to persons with multiple chronic conditions? We applied Thorne's interpretive description approach, interviewing 18 spouses who provided a rich description of their caregiving experience; interviews were transcribed verbatim and thematically analysed. Themes were categorized according to challenges encountered, rewards gleaned, and sustaining strategies employed by participants in caregiving to their spouse with multiple chronic conditions. Unique findings relate to the challenges inherent in decision-making within the context of multiple chronic conditions. This article begins to address the gap in the literature regarding the caregiving experience within the context of multiple chronic conditions.

Factors influencing adult physical health after controlling for current health conditions: evidence from a british cohort.

Full Text Available This study explored a longitudinal data set of 6875 British adults examining the effects of parental social status (measured at birth, cognitive ability (at age 11 yrs, personality traits, education and occupational attainment on physical health and functioning (all measured at age 50 yrs, after taking account of current health conditions (number of illness. Correlation analysis showed that parental social class, childhood cognitive ability, education and occupation, and two personality traits (Emotional Stability/Neuroticism, and Conscientiousness were all significantly associated with adult physical health variables. Structural equation modelling showed that health conditions and personality traits were significantly, and inversely, associated with physical health (indicated by good daily physical functioning, relative absence of pain, perceived health, and low level of limitations at work due to physical health. Parental social status, childhood intelligence, educational and occupational attainment were all modestly, but significantly and directly, associated with adult physical health. The effect of childhood intelligence on adult physical health was, in part, mediated through Emotional Stability and Conscientiousness. After controlling for health conditions Emotional Stability was the strongest predictor of physical health. Implications and limitations are discussed.

IMPROVEMENT OF ROAD-HOLDING ABILITY FOR “BELARUS” TRACTORS

V. P. Boikov

2016-01-01

Full Text Available Introduction of new efficient braking systems for energy-packed tractors is of great importance for agricultural production. Foreign tractor manufacturing companies are implementing brake systems and in addition to their main function they fulfil function for holding of the given driving direction. The paper considers achievements in the field of electronic systems for tractor road-holding ability. A diagram on proportion of high-power tractors in total export volume of tractors and machinery manufactured in Belarus in the period of 2007–2010 has been drawn in the paper. The paper also proposes a comparative diagram on tractor speeds of international manufacturers which can serve as indicators of speed and road-holding ability of tractors with special electronic systems and without them. The paper contains an analysis of various braking mechanisms of planetary gears and detailed description of their design. A scheme of a laboratory facility for investigation of planetary gear usage as a breaking mechanism while changing conditions of jamming has been presented in the paper. The paper provides description on graph dependencies of current strength and voltage on as a function of the braking torque which is applied to a planetary gear. Nowadays energy-packed “Belarus”-tractors of Class 5 do not have a separate braking for each of four wheels. Therefore, it is proposed to use planetary gearbox of the rear-axle drive being available in every wheel as the basis of a service brake with the purpose to implement the described design. Using such scheme it is possible to execute an introduction of electronic systems for road-holding ability. A generalized scheme of an electronic system for tractor road-holding ability which can ensure separate breaking of all tractor wheels has been drawn out on the basis of the existing automotive electronic systems.

Breath-Hold Diving.

Science.gov (United States)

Fitz-Clarke, John R

2018-03-25

Breath-hold diving is practiced by recreational divers, seafood divers, military divers, and competitive athletes. It involves highly integrated physiology and extreme responses. This article reviews human breath-hold diving physiology beginning with an historical overview followed by a summary of foundational research and a survey of some contemporary issues. Immersion and cardiovascular adjustments promote a blood shift into the heart and chest vasculature. Autonomic responses include diving bradycardia, peripheral vasoconstriction, and splenic contraction, which help conserve oxygen. Competitive divers use a technique of lung hyperinflation that raises initial volume and airway pressure to facilitate longer apnea times and greater depths. Gas compression at depth leads to sequential alveolar collapse. Airway pressure decreases with depth and becomes negative relative to ambient due to limited chest compliance at low lung volumes, raising the risk of pulmonary injury called "squeeze," characterized by postdive coughing, wheezing, and hemoptysis. Hypoxia and hypercapnia influence the terminal breakpoint beyond which voluntary apnea cannot be sustained. Ascent blackout due to hypoxia is a danger during long breath-holds, and has become common amongst high-level competitors who can suppress their urge to breathe. Decompression sickness due to nitrogen accumulation causing bubble formation can occur after multiple repetitive dives, or after single deep dives during depth record attempts. Humans experience responses similar to those seen in diving mammals, but to a lesser degree. The deepest sled-assisted breath-hold dive was to 214 m. Factors that might determine ultimate human depth capabilities are discussed. © 2018 American Physiological Society. Compr Physiol 8:585-630, 2018. Copyright © 2018 American Physiological Society.

The hold-time effects on the low cycle fatigue behaviors of 316 SS in PWR primary environment

International Nuclear Information System (INIS)

Lee, Junho; Hong, Jong-Dae; Seo, Myung-Gyu; Jang, Changheui

2015-01-01

The effects of the environments on fatigue life of the structural materials used in nuclear power plants (NPPs) were known to be significant according to the extensive test results. Accordingly, the fatigue analysis procedures and the design fatigue curves were proposed in the ASME Code. However, the implication that the existing ASME design fatigue curves did not sufficiently reflect the effect of the operation conditions of nuclear power plants emerged as an issue to be resolved. One of possible reasons to explain the discrepancy is that the laboratory test conditions do not represent the actual plant transients. Therefore, it is necessary to clarify the effects of light water environments on fatigue life while considering more plant-relevant transient conditions such as hold-time. For this reason, this study will focus on the fatigue life of type 316 stainless steel (SS) in the pressurized water reactor (PWR) environments while incorporating the hold-time during the low cycle fatigue (LCF) test in simulated PWR environments. The objective of this study is to characterize the effects of hold-time on the fatigue life of austenitic stainless steels in PWR environments in comparison with the existing fixed strain rate results. Low cycle fatigue life tests were conducted for the type 316 SS in 310 .deg. C air and simulated PWR environments. To simulate the heat-up and cool-down transient, sub-peak strain holding during the down-hill of strain amplitude was chosen. Currently, LCF tests with 60 seconds holding are in progress. The 0.4, 0.04%/s strain rate condition test results are presented in this study, which shows somewhat longer fatigue life

Full Text Available Background: Numerous studies have documented on flexibility of muscles. Flexibility is defined as the ability of the muscles to lengthen allowing one joint or more than one joint in a series to move through a range of motion .Flexibility allows tissue to accommodate more easily to stress thus minimizing or preventing muscle injury. But this study sought to identify the study to compare the effectiveness of Static stretch and Hold relax technique over the hamstring flexibility. Methods: 30 healthy male adults with Hamstring tightness aged 21 to 35 years selected from general population through simple randomized technique. Samples are divided into two groups, static stretch Group-I(no.15 and Group-II Hold relax (no.=15.The outcome was measured with help of sit & reach test to see the Hamstring flexibility. Results: Comparison of the post test values of the group I and group II shows a significant difference between the outcomes of two groups with a “t” calculated value of 0.738 (unpaired “t” test. Conclusion: Both static stretch and hold relax Technique can cause very highly significant result in Hamstring Flexibility, further comparison shows very high significant difference between two groups and concludes that hold relax is better than static stretch in Hamstring Flexibility.

Life time calculations for LCF loading combined with tensional hold periods

International Nuclear Information System (INIS)

Bocek, M.; Armas, A.; Piel, D.

1983-01-01

The life time in high amplitude strain cycling with tensional hold periods is analysed presuming that creep failure damage is life determining. The life fraction rule (LFR) is used to calculate the life time consumpted during the dwell period in strain controlled tests as well as during tensional hold time stress cycles. It follows from the present investigation that stress relaxation occurring during the strain hold periods plays the dominant influence upon the relationship between life and dwell time. For strong stress relaxation (e.g. high temperature) less damage is accumulated as compared to suppressed relaxation (low temperature). The damage in stress relaxation is calculated by means of the LFR and the results are compared to experiments conducted on Zircaloy-4 and the austenitic stainless stell Type AISI 304. From the very good agreement between both it is concluded that under the loading conditions considered, creep failure damage is the main life determining damage contribution. (orig.)

Forty-seven people with spinal cord injury participated and answered the self-report questionnaire. The group under study was predominantly male (92%), under 40 years of age (47%), and had low educational level (76%). The most frequent risk factors related to the lifestyle were: smoking (28%), alcohol consumption (36%), coffee consumption (92%) and being physically inactive (64%). Association was found between having four or more risk factors related to lifestyle and the loss of appetite, as well as constipation. . The actual inadequate lifestyle is associated with the health conditions of patients, and the nursing team should pay special attention to the education and promotion of health related to people with spinal cord injury.

Development of a liquid-holding technique for the study of DNA-repair in human diploid fibroblasts

International Nuclear Information System (INIS)

Simons, J.W.I.M.

1979-01-01

Liquid-holding conditions can be obtained for human diploid skin fibro-blasts by keeping confluent cultures stationary over periods of 7 days or longer by means of conditioned medium. Under this condition recovery of radiation damage induced by ultraviolet light or X-rays is observed as an increase in cloning efficiency. The amount of recovery when expressed in a dose-modifying-factor appears higher than in bacteria and yeast. The repair-deficient human cell strains XP25Ro and XP7Be (xeroderma pigmentosum from complementation groups A and D respectively) exhibit less but still discernible recovery after UV-irradiation and the same was observed for AT5Bi (ataxia telangiectasia) after X-irradiation. Experiments on mutation induction indicated that the repair which takes place during liquid holding of UV-irradiated XP7Be cells reduces the mutant frequency considerably while after liquid holding of UV-irradiated wild-type cells the same or lower mutant frequencies were found for the lower exposures and the same or higher mutant frequencies for the higher exposures.

Background/Objectives Trauma exposure and posttraumatic stress disorder (PTSD) may increase risk for medical conditions in older adults. We present findings on past-year medical conditions associated with lifetime trauma exposure, and full and partial PTSD, in a nationally representative sample of U.S. older adults. Design, Setting, Participants, and Measurements Face-to-face diagnostic interviews were conducted with 9,463 adults aged 60 and older in the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression analyses adjusting for sociodemographics and psychiatric comorbidity evaluated associations between PTSD status and past-year medical disorders; linear regression models evaluated associations with past-month physical functioning. Results After adjustment for sociodemographic characteristics and comorbid lifetime mood, anxiety, substance use, attention-deficit/hyperactivity, and personality disorders, respondents with lifetime PTSD were more likely than trauma controls to report being diagnosed by a healthcare professional with hypertension, angina pectoris, tachycardia, other heart disease, stomach ulcer, gastritis, and arthritis (odds ratios [ORs]=1.3–1.8); they also scored lower on a measure of physical functioning than controls and respondents with partial PTSD. Respondents with lifetime partial PTSD were more likely than controls to report past-year diagnoses of gastritis (OR=1.7), angina pectoris (OR=1.5), and arthritis (OR=1.4), and reported worse physical functioning. Number of lifetime traumatic event types was associated with most of the medical conditions assessed; adjustment for these events reduced the magnitudes of and rendered non-significant most associations between PTSD status and medical conditions. Conclusion Older adults with lifetime PTSD have elevated rates of several physical health conditions, many of which are chronic disorders of aging, and poorer physical functioning.

We examine the determinants of corporate cash holdings in Australia and the impact on shareholder wealth of holding excess cash. Our results show that a trade-off model best explains the level of a firm’s cash holdings in Australia. We find that 'transitory' excess cash firms earn significantly higher risk-adjusted returns compared to 'persistent' excess cash firms, suggesting that the market penalises firms that hoard cash. The marginal value of cash also declines with larger cash balances, ...

Role of DNA polymerase I in liquid holding recovery of uv-irradiated Escherichia coli

Energy Technology Data Exchange (ETDEWEB)

Tang, M S; Patrick, M H [Texas Univ., Dallas (USA)

1977-09-01

Excision of cyclobutyl dipyrimidines from, and accumulation of strand interruptions in DNA of different strains of E.coli K12 were determined during liquid holding recovery after uv irradiation. The extent of Pyr <> Pyr excision was the same (20 to 25%) for both a polA mutant (E.coli P3478) and its parental wild type strain (E.coli W3110); however, single strand interruptions accumulated during liquid holding of polA cells, but not in the parental strain. In contrast, excision was greatly reduced in a mutant (KMBL 1789) which is defective in the 5' ..-->.. 3' exonucleolytic function of DNA polymerase I. These data suggest that excision and resynthesis during liquid holding are carried out primarily, if not entirely, by DNA polymerase I. It is further concluded that excision alone is both a necessary and sufficient condition to elicit liquid holding recovery, and that this excision requires a functional polymerase I 5' ..-->.. 3' exonuclease.

Understanding unskilled work as a condition for participation in adult education and training

DEFF Research Database (Denmark)

Kondrup, Sissel

2015-01-01

This article discusses how to comprehend why people working unskilled jobs are less likely than other groups to position themselves as educable subjects and engage in adult education and training. This article outlines how different research traditions examining recruitment to and participation...... in adult education and training reveal and explain distinctive participation patterns. These traditions are critically reviewed in order to identify how they provide certain understandings and entail certain blind spots. The review reveals a striking absence of research into unskilled work and thus...... a tendency to overlook how engagement in specific kinds of work condition people’s perception of adult education and training. It is finally argued that future research must pay closer attention to people’s specific work-life and examine how engagement in specific historical, social and material (changing...

This review is an update of a previously published review in the Cochrane Database of Systematic Reviews (Issue 1, 2010) on 'Vitamin D for the treatment of chronic painful conditions in adults'.Vitamin D is produced in the skin after exposure to sunlight and can be obtained through food. Vitamin D deficiency has been linked with a range of conditions, including chronic pain. Observational and circumstantial evidence suggests that there may be a role for vitamin D deficiency in the aetiology of chronic painful conditions. To assess the efficacy and safety of vitamin D supplementation in chronic painful conditions when tested against placebo or against active comparators. For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and EMBASE to February 2015. This was supplemented by searching the reference lists of retrieved articles, reviews in the field, and online trial registries. We included studies if they were randomised double-blind trials of vitamin D supplementation compared with placebo or with active comparators for the treatment of chronic painful conditions in adults. Two review authors independently selected the studies for inclusion, assessed methodological quality, and extracted data. We did not undertake pooled analysis due to the heterogeneity of the data. Primary outcomes of interest were pain responder outcomes, and secondary outcomes were treatment group average pain outcomes and adverse events. We included six new studies (517 participants) in this review update, bringing the total of included studies to 10 (811 participants). The studies were heterogeneous with regard to study quality, the chronic painful conditions that were investigated, the dose of vitamin D given, co-interventions, and the outcome measures reported. Only two studies reported responder pain outcomes; the other studies reported treatment group average outcomes only. Overall, there was no consistent pattern that vitamin D treatment was

Sports-related lung injury during breath-hold diving

Full Text Available The number of people practising recreational breath-hold diving is constantly growing, thereby increasing the need for knowledge of the acute and chronic effects such a sport could have on the health of participants. Breath-hold diving is potentially dangerous, mainly because of associated extreme environmental factors such as increased hydrostatic pressure, hypoxia, hypercapnia, hypothermia and strenuous exercise. In this article we focus on the effects of breath-hold diving on pulmonary function. Respiratory symptoms have been reported in almost 25% of breath-hold divers after repetitive diving sessions. Acutely, repetitive breath-hold diving may result in increased transpulmonary capillary pressure, leading to noncardiogenic oedema and/or alveolar haemorrhage. Furthermore, during a breath-hold dive, the chest and lungs are compressed by the increasing pressure of water. Rapid changes in lung air volume during descent or ascent can result in a lung injury known as pulmonary barotrauma. Factors that may influence individual susceptibility to breath-hold diving-induced lung injury range from underlying pulmonary or cardiac dysfunction to genetic predisposition. According to the available data, breath-holding does not result in chronic lung injury. However, studies of large populations of breath-hold divers are necessary to firmly exclude long-term lung damage.

Numerous people with chronic conditions like to use traditional Chinese medicine (TCM) treatment, or integrated treatment of TCM and Western medicine (WM). Our study explored the associations between multiple chronic conditions (MCC) and TCM use and the use of specific types of TCM therapy among adults in Taiwan. In addition, we explored the TCM use of adults with seven common types of chronic conditions. In our study, a national representative sample in 2005 was used. The Chronic Condition Indicator and the Clinical Classifications System created by the U.S. Agency for Healthcare Research and Quality were used to define the number of chronic conditions of adults. Logistic regressions adjusted for demographic characteristics were used to analyze the associations. The frequency of TCM use among adults with different numbers of chronic conditions was quantified. TCM use for adults with ≥5 chronic conditions (odds ratio [OR] 1.86) was higher than TCM use for adults with 2-4 chronic conditions (OR 1.51) and TCM use for adults with one chronic condition (OR 1.48). The increase in the OR of the use of Chinese herbs and traumatology manipulative therapy according to the number of chronic conditions was not as substantial as that of acupuncture-moxibustion. The frequency of TCM use exhibited an increasing trend with the increase in the number of chronic conditions (pherbs use, traumatology manipulative therapy use, and, particularly, acupuncture-moxibustion use increased as the number of chronic conditions increased. We suggest that government policy makers emphasize administering integrated TCM and WM care to people with chronic conditions or MCC.

2013-01-01

Preventing and ameliorating chronic conditions has long been a priority in the United States; however, the increasing recognition that people often have multiple chronic conditions (MCC) has added a layer of complexity with which to contend. The objective of this study was to present the prevalence of MCC and the most common MCC dyads/triads by selected demographic characteristics. We used respondent-reported data from the 2010 National Health Interview Survey (NHIS) to study the US adult civilian noninstitutionalized population aged 18 years or older (n = 27,157). We categorized adults as having 0 to 1, 2 to 3, or 4 or more of the following chronic conditions: hypertension, coronary heart disease, stroke, diabetes, cancer, arthritis, hepatitis, weak or failing kidneys, chronic obstructive pulmonary disease, or current asthma. We then generated descriptive estimates and tested for significant differences. Twenty-six percent of adults have MCC; the prevalence of MCC has increased from 21.8% in 2001 to 26.0% in 2010. The prevalence of MCC significantly increased with age, was significantly higher among women than men and among non-Hispanic white and non-Hispanic black adults than Hispanic adults. The most common dyad identified was arthritis and hypertension, and the combination of arthritis, hypertension, and diabetes was the most common triad. The findings of this study contribute information to the field of MCC research. The NHIS can be used to identify population subgroups most likely to have MCC and potentially lead to clinical guidelines for people with more common MCC combinations. PMID:23618545

Progress Report on Long Hold Time Creep Fatigue of Alloy 617 at 850°C

International Nuclear Information System (INIS)

Carroll, Laura Jill

2015-01-01

Alloy 617 is the leading candidate material for an intermediate heat exchanger for the very high temperature reactor. To evaluate the behavior of this material in the expected service conditions, strain-controlled cyclic tests that include long hold times up to 240 minutes at maximum tensile strain were conducted at 850°C. In terms of the total number of cycles to failure, the fatigue resistance decreased when a hold time was added at peak tensile strain. Increases in the tensile hold duration degraded the creep-fatigue resistance, at least to the investigated strain controlled hold time of up to 60 minutes at the 0.3% strain range and 240 minutes at the 1.0% strain range. The creep-fatigue deformation mode is considered relative to the lack of saturation, or continually decreasing number of cycles to failure with increasing hold times. Additionally, preliminary values from the 850°C creep-fatigue data are calculated for the creep-fatigue damage diagram and have higher values of creep damage than those from tests at 950°C.

2017-10-01

Full Text Available Abstract Background Aging is often associated with the challenge of navigating daily tasks with a painful chronic medical illness. Yet, there is concern of the number of older adults impacted with more than one chronic condition. Despite the increasing number of adults diagnosed with diabetes and comorbid chronic illnesses, there remains a lack of understanding in how multiple illnesses relate to experiences of pain. To assess the association between multiple chronic conditions and pain, this study aimed to identify clusters of chronic medical conditions and their association with pain among a sample of older Black and White adults diagnosed with diabetes. Methods Two hundred and thirty-six participants responded to a series of questions assessing pain frequency and severity, as well as health and social characteristics. A factor analysis was used to categorize clusters of medical conditions, and multiple regression models were used to examine predictors of pain. Results Seven of the assessed chronic medical conditions loaded on three factors, and accounted for 57.2% of the total variance, with heart disease (factor 1 accounting for 21.9%, musculoskeletal conditions (factor 2 for another 18.4%, and factor 3 (microvascular diseases accounting for a final 16.9% of the variability among the chronic medical conditions. Covariate-adjusted models showed that fewer years of education and higher scores on the microvascular and musculoskeletal conditions factors were associated with higher pain frequency, with the musculoskeletal conditions factor being the strongest predictor. Conclusions Findings from this study compliment existent literature underscoring the prevalence and importance of comorbid diagnoses in relation to pain. Examining health-related factors beyond a single disease diagnosis also provides an opportunity to explore underlying disease co-occurrences that may persist beyond organ system classifications.

Economic Conditions of Young Adults Before and After the Great Recession.

2018-01-01

Transition to adulthood has undoubtedly changed in the last few decades. For youth today, an important marker of adulthood is self-actualization in their professional career, and, consequently, also the achievement of stable financial conditions. Economic conditions of youth are greatly subject to fluctuations in the economy, and the subsequent governmental response. Using the Luxembourg Income Study, this work investigates the trends in income from work of young adults before and after the Great Recession of 2008 in five countries-US, UK, Norway, Germany, and Spain. The findings showed deterioration in economic conditions of young men, but with differences across countries. Young women suffered less from the crisis, and in some countries, their economic situation improved. The general negative trend was especially pronounced for those with high education, which is primarily because they stayed in education longer.

We evaluated the effect of commercial times and temperatures for searing, cooking, and holding on the destruction of Escherichia coli O157:H7 (ECOH) within mechanically tenderized prime rib. Boneless beef ribeye was inoculated on the fat side with ca. 5.7 log CFU/g of a five-strain cocktail of ECOH and then passed once through a mechanical tenderizer with the fat side facing upward. The inoculated and tenderized prime rib was seared by broiling at 260°C for 15 min in a conventional oven and then cooked in a commercial convection oven at 121.1°C to internal temperatures of 37.8, 48.9, 60.0, and 71.1°C before being placed in a commercial holding oven maintained at 60.0°C for up to 8 h. After searing, ECOH levels decreased by ca. 1.0 log CFU/g. Following cooking to internal temperatures of 37.8 to 71.1°C, pathogen levels decreased by an additional ca. 2.7 to 4.0 log CFU/g. After cooking to 37.8, 48.9, or 60.0°C and then warm holding at 60.0°C for 2 h, pathogen levels increased by ca. 0.2 to 0.7 log CFU/g. However, for prime rib cooked to 37.8°C, pathogen levels remained relatively unchanged over the next 6 h of warm holding, whereas for those cooked to 48.9 or 60.0°C pathogen levels decreased by ca. 0.3 to 0.7 log CFU/g over the next 6 h of warm holding. In contrast, after cooking prime rib to 71.1°C and holding for up to 8 h at 60.0°C, ECOH levels decreased by an additional ca. 0.5 log CFU/g. Our results demonstrated that to achieve a 5.0-log reduction of ECOH in blade tenderized prime rib, it would be necessary to sear at 260°C for 15 min, cook prime rib to internal temperatures of 48.9, 60.0, or 71.1°C, and then hold at 60.0°C for at least 8 h.

Research on aging has indicated that whereas deliberative cognitive processes decline with age, emotional processes are relatively spared. To examine the implications of these divergent trajectories in the context of health care choices, we investigated whether instructional manipulations emphasizing a focus on feelings or details would have differential effects on decision quality among younger and older adults. We presented 60 younger and 60 older adults with health care choices that required them to hold in mind and consider multiple pieces of information. Instructional manipulations in the emotion-focus condition asked participants to focus on their emotional reactions to the options, report their feelings about the options, and then make a choice. In the information-focus condition, participants were instructed to focus on the specific attributes, report the details about the options, and then make a choice. In a control condition, no directives were given. Manipulation checks indicated that the instructions were successful in eliciting different modes of processing. Decision quality data indicate that younger adults performed better in the information-focus than in the control condition whereas older adults performed better in the emotion-focus and control conditions than in the information-focus condition. Findings support and extend extant theorizing on aging and decision making as well as suggest that interventions to improve decision-making quality should take the age of the decision maker into account.

Transition from pediatric to adult health care is a vulnerable period for adolescents and young adults. Challenges include paucity of validated measures to assess patients' transition readiness. We evaluated the Transition Readiness Assessment Questionnaire (TRAQ) in adolescents and young adults with rheumatic, gastrointestinal, and endocrine disorders. We examined whether baseline TRAQ scores and other demographic variables predicted transition to adult care over a three year follow up period. In this descriptive study at a single institution, eighty-nine adolescents at a single pediatric academic medical center completed demographic and medical history surveys and the TRAQ and were followed over 3 years by telephone interview to determine whether they had transitioned to adult subspecialty care. Transition was defined as attending at least one adult subspecialty appointment. Multivariable logistic regression and Cox proportional hazards regression models were used to determine whether TRAQ scores predicted time to transition. Of the participants, 56% had rheumatic, 21% endocrine, and 23% gastrointestinal conditions. The TRAQ self-management domain score was not significantly associated with age, gender, socioeconomic status, or specialty. The TRAQ self-advocacy score increased with age. Baseline TRAQ scores did not predict transition or time to transition over three years. In this cohort of adolescents and young adults who were 16 to 23 years of age at enrollment, 48% transitioned to adult care over three years of follow up. Nearly half reported not discussing transition with provider or seeing provider independently for part of visit. Older age but not other demographic variables nor baseline TRAQ score predicted transition or time to transition to an adult subspecialty provider; however, a there was a trend towards shorter time to transition with the highest quartile TRAQ scores.

Disclosure of personal medical information: differences among parents and affected adults for genetic and nongenetic conditions.

Protecting the confidentiality of medical information has been an issue of great interest in the fields of bioethics, public policy, and law. Few empirical studies have addressed patient experiences and attitudes toward disclosure of private medical information in multiple contexts such as health insurance, employment, and the family. Furthermore, it is unclear whether differences exist in experiences and attitudes about privacy between those living with a serious medical condition versus those who have a child with a medical condition. The study sought to determine whether attitudes and experiences related to medical privacy and confidentiality differ between affected adults and parents of affected children. Interviews were conducted with 296 adults and parents of children with sickle cell disease (SCD), cystic fibrosis (CF), or diabetes mellitus (DM). This cross-sectional study collected data regarding their experiences, attitudes, and beliefs concerning medical privacy and confidentiality. Multinomial logistic regression analysis was conducted on quantitative data. Qualitative analysis was conducted on data from open-ended response items. Parents disclose their child's diagnosis to others more often than affected adults disclose their own disease status. Parents are less likely than affected adults to regret their disclosure, to hope others do not find out, to have been pressured to share information, and to be asked about their disease by employers. Affected adults express greater concern about disclosure, a greater prevalence and greater fear of discrimination, and experience greater pressure from family members to disclose. Clinicians and researchers working with these populations should consider these differences in privacy and disclosure. Further study is necessary to examine the implications of these differences in attitudes and experiences concerning insurance, employment, and social interactions among persons with these conditions.

The Asian citrus citrus psyllid, Diaphorina citri Kuwayama, transmits a bacterium that causes huanglongbing in citrus. Frequent and repeated use of neurotoxic insecticides against D. citri has resulted in the development of insecticide resistance. We evaluated the effects of the juvenile hormone analog methoprene on egg hatch, nymphal development, adult emergence, reproduction and behavior of D. citri. Methoprene significantly reduced the viability of eggs that were between 0 and 4 days old. Egg hatch of 0-48-h-old and 49-96-h-old eggs was 8 and 9%, respectively, when treated with 320 µg mL(-1) of methoprene. Methoprene caused significant mortality of first-, third- and fifth-instar D. citri nymphs and reduced adult emergence as compared with controls. Methoprene caused less than 5% adult emergence when first- and third-instar stages were treated, respectively, and less than 40% adult emergence when fifth instars were treated. Reduced fertility of females was observed when they emerged from methoprene-treated fifth instars. Methoprene was effective in reducing egg hatch, suppressing nymphal development and decreasing adult emergence of D. citri under laboratory conditions. Treatment of fifth instars reduced the fertility of females. Methoprene might be a possible tool for integrated management of D. citri. © 2015 Society of Chemical Industry.

Physical activity as a mediator of the impact of chronic conditions on quality of life in older adults.

Sawatzky, Richard; Liu-Ambrose, Teresa; Miller, William C; Marra, Carlo A

2007-12-19

Chronic conditions could negatively affect the quality of life of older adults. This may be partially due to a relative lack of physical activity. We examined whether physical activity mediates the relationship between different chronic conditions and several health outcomes that are important to the quality of life of older adults. The data were taken from the Canadian Community Health Survey (cycle 1.1), a cross-section survey completed in 2001. Only respondents who were 65 years or older were included in our study (N = 22,432). The Health Utilities Index Mark 3 (HUI3) was used to measure overall quality of life, and to measure selected health outcomes (dexterity, mobility, pain, cognition, and emotional wellbeing) that are considered to be of importance to the quality of life of older adults. Leisure-time physical activity was assessed by determining weekly energy expenditure (Kcal per week) based on the metabolic equivalents of self-reported leisure activities. Linear and logistic regression models were used to determine the mediating effect of leisure-time physical activity while controlling for demographic variables (age and sex), substance use (tobacco use and alcohol consumption), and obesity. Having a chronic condition was associated with a relative decrease in health utility scores and a relative increase in mobility limitations, dexterity problems, pain, emotional problems (i.e., decreased happiness), and cognitive limitations. These negative consequences could be partially attributed to a relative lack of physical activity in older adults with a chronic condition (14% mediation for the HUI3 score). The corresponding degree of mediation was 18% for mobility limitations, 5% for pain, and 13% for emotional wellbeing (statistically significant mediation was not observed for the other health attributes). These values varied with respect to the different chronic conditions examined in our study. Older adults with chronic conditions are less likely to engage

The role of DNA polymerase I in liquid holding recovery of UV-irradiated Escherichia coli

1977-01-01

Excision of cyclobutyl dipyrimidines from, and accumulation of strand interruptions in, DNA of different strains of E.coli K12 were determined during liquid holding recovery after UV irradiation. The extent of Pyr Pyr excision was the same (20 to 25%) for both a polA mutant (E.coli P3478) and its parental wild type strain (E.coli W3110); however, single strand interruptions accumulated during liquid holding of polA cells, but not in the parental strain. In contrast, excision was greatly reduced in a mutant (KMBL 1789) which is defective in the 5' → 3' exonucleolytic function of DNA polymerase I. These data suggest that excision and resynthesis during liquid holding are carried out primarily, if not entirely, by DNA polymerase I. It is further concluded that excision alone is both a necessary and sufficient condition to elicit liquid holding recovery, and that this excision requires a functional polymerase I 5' → 3' exonuclease.

Experiencing El Niño conditions during early life reduces recruiting probabilities but not adult survival

Rodríguez, Cristina; Drummond, Hugh

2018-01-01

In wild long-lived animals, analysis of impacts of stressful natal conditions on adult performance has rarely embraced the entire age span, and the possibility that costs are expressed late in life has seldom been examined. Using 26 years of data from 8541 fledglings and 1310 adults of the blue-footed booby (Sula nebouxii), a marine bird that can live up to 23 years, we tested whether experiencing the warm waters and food scarcity associated with El Niño in the natal year reduces recruitment or survival over the adult lifetime. Warm water in the natal year reduced the probability of recruiting; each additional degree (°C) of water temperature meant a reduction of roughly 50% in fledglings' probability of returning to the natal colony as breeders. Warm water in the current year impacted adult survival, with greater effect at the oldest ages than during early adulthood. However, warm water in the natal year did not affect survival at any age over the adult lifespan. A previous study showed that early recruitment and widely spaced breeding allow boobies that experience warm waters in the natal year to achieve normal fledgling production over the first 10 years; our results now show that this reproductive effort incurs no survival penalty, not even late in life. This pattern is additional evidence of buffering against stressful natal conditions via life-history adjustments. PMID:29410788

Breath holding endurance: stability over time and relationship with self-assessed persistence

2017-09-01

Full Text Available Breath holding (BH endurance has been suggested as a measure of the distress tolerance that could predict the outcome of attempts to implement behavior changes, such as stopping smoking or illicit substance use. It is not known however, to what degree BH endurance is a variable trait that may vary depending on situational context, or a stable state characteristic. We measured BH in two groups of participants at baseline and 22 and 89 days (N = 62 and N = 41 post-baseline and in a third group at multiple times points across a 5-week period (N = 44. Participants also filled out a questionnaire created to assess their perceived persistence compared to peers. Correlations were found between baseline and final BH measures (r’s > 0.67, p’s < 0.0001 at all time points. When groups were combined, regardless of time point, Spearman’s rank correlation showed a strong positive correlation (rs = 0.66, p < 0.0001. Self-assessed persistence was not related to BH endurance. This study provides evidence of the stability of BH across time when tested under the same conditions in young adults. Further research is needed to clarify whether BH is linked to behavioral outcomes.

To examine the associations of job acquisition and job retention to secondary conditions, hospitalizations, and nursing home stays for adults with spinal cord injury (SCI). Retrospective analysis of longitudinal data from multicenter study. Community setting. Two samples of adults participating in the SCI Model Systems; the first sample consisted of persons who reported being unemployed at follow-up (n=9501); the second sample consisted of those who reported working at follow-up (n=5,150). Not applicable. Job acquisition (change from not working at 1 anniversary of injury to working at the following data collection) and job retention (maintenance of work between 2 assessment periods). Discrete time hazard modeling was used to assess how secondary conditions affect job acquisition. After controlling for the effects of demographic and injury characteristics, hospitalizations within the last 12 months were associated with decreased chance of having obtained employment. Hierarchic logistic regression analyses were used to examine job retention. Hospitalizations and the presence of PUs were associated with lower odds of job retention once demographic and injury characteristics were controlled. Secondary conditions from the previous assessment period were not significantly related to either job acquisition or job retention after the variance from demographic and injury characteristics and current secondary conditions were controlled. Hospitalization, as well as a limited number of secondary conditions, were associated with reduced odds of both job acquisition and job retention among adults with SCI. Interventions that can prevent secondary conditions and reduce the need for hospitalizations may be beneficial in improving employment for this population.

1997-01-01

We examine the determinants and implications of holdings of cash and marketable" securities by publicly traded U.S. firms in the 1971-1994 period. Firms with strong growth" opportunities and riskier cash flows hold relatively high ratios of cash to total assets. Firms" that have the greatest access to the capital markets (e.g. large firms and those with credit" ratings) tend to hold lower ratios of cash to total assets. These results are consistent with the" view that firms hold liquid assets...

Balancing on a slackline: 8-year-olds vs. adults

Directory of Open Access Journals (Sweden)

Andrea Melanie Schärli

2013-04-01

Full Text Available Children are less stable than adults during static upright stance. We investigated whether the same holds true for a task that was novel for both children and adults and highly dynamic: single-legged stance on a slackline. We compared 8 year olds with young adults and assessed the following outcome measures: time on the slackline, stability on the slackline (calculated from slackline reaction force, gaze movement, head-in-space rotation and translation, trunk-in-space rotation, and head-on-trunk rotation. 8-year-olds fell off the slackline quicker and were generally less stable on the slackline than adults. 8-year-olds also showed more head-in-space rotation and translation, and more gaze variability around a visual anchor point they were instructed to fixate. Trunk-in-space and head-on-trunk rotation did not differ between groups. The results imply that the lower postural stability of 8 year-olds compared to adults – as found in simple upright stance – holds true for dynamic, novel tasks in which adults lack the advantage of more practice. They also suggest that the lack of head and gaze stability constitutes an important limiting factor in children’s ability to master such tasks.

This paper presents three examples of power ramp tests performed in the OSIRIS experimental reactor, located at Saclay (France). The rods tested during these experiments stem from the same segmented 'mother' rod, pre-irradiated for two cycles in a French PWR. They underwent very similar power transient conditions, except for the hold time at Ramp Terminal Level (RTL) - respectively 41.5 kW/m (J12/2), 40.7 kW/m (J12/4) and 39.5 kW/m (J12/5) for RTL, but zero (J12/2), 16 minutes (J12/4) and 12 hours (J12/5) for the hold time at RTL. No failure was detected for any of the three experiments despite the relatively high mechanical stress applied to the cladding in the case of J12/2. Moreover, although no hold time was maintained at RTL, a permanent deformation clearly appeared on the clad during the power transient. An analysis of the cladding deformation has also been undertaken concerning the J12/2, J12/4 and J12/5 experiments. This study was realized by carrying out post-calculations of the three experiments with a 2D fuel modelling code using the finite element method. The computations satisfactorily reproduce the influence of hold time on the cladding deformation during the power transients, especially for the J12/2 and J12/4 experiments with hold times enclosing the failure times experimentally observed for power ramp tests. For the hold time of 12 hours, the micrographic observations of the fuel, compared to the case of the 16 minutes hold time, support the hypothesis of weak but noticeable gaseous swelling. (author)

Adults aged 85 and older, often referred to as the oldest-old, are the fastest-growing segment of the population. The rapidly increasing number of older adults with chronic and multiple medical conditions poses challenges regarding their driving safety. To investigate the effect of advanced age on driving safety in drivers with medical conditions. We categorized 3,425 drivers with preexisting medical conditions into four age groups: middle-aged (55-64 years, n = 1,386), young-old (65-74 years, n = 1,013), old-old (75-84 years, n = 803), or oldest-old (85 years and older, n = 223). All underwent a formal driving evaluation. The outcome measures included fitness to drive recommendation by the referring physician, comprehensive fitness to drive decision from an official driving evaluation center, history of motor vehicle crashes (MVCs), and history of traffic violations. The oldest-old reported more cardiopulmonary and visual conditions, but less neurological conditions than the old-old. Compared to the middle-aged, the oldest-old were more likely to be considered unfit to drive by the referring physicians (odds ratio [OR] = 4.47, 95% confidence interval [CI] 2.20-9.10) and by the official driving evaluation center (OR = 2.74, 95% CI 1.87-4.03). The oldest-old reported more MVCs (OR = 2.79, 95% CI 1.88-4.12) compared to the middle-aged. Advanced age adversely affected driving safety outcomes. The oldest-old are a unique age group with medical conditions known to interfere with safe driving. Driving safety strategies should particularly target the oldest-old since they are the fastest-growing group and their increased frailty is associated with severe or fatal injuries due to MVCs. © 2018 S.

Links between primary occupation and functional limitations among older adults in Mexico

Directory of Open Access Journals (Sweden)

Hiram Beltrán-Sánchez

2017-12-01

Full Text Available Social inequalities in health and disability are often attributed to differences in childhood adversity, access to care, health behavior, residential environments, stress, and the psychosocial aspects of work environments. Yet, disadvantaged people are also more likely to hold jobs requiring heavy physical labor, repetitive movement, ergonomic strain, and safety hazards. We investigate the role of physical work conditions in contributing to social inequality in mobility among older adults in Mexico, using data from the Mexican Health and Aging Survey (MHAS and an innovative statistical modeling approach. We use data on categories of primary adult occupation to serve as proxies for jobs with more or less demanding physical work requirements. Our results show that more physically demanding jobs are associated with mobility limitations at older ages, even when we control for age and sex. Inclusion of job categories attenuates the effects of education and wealth on mobility limitations, suggesting that physical work conditions account for at least part of the socioeconomic differentials in mobility limitations in Mexico.

Holding back, or withholding discussion of disease-related thoughts and emotions, is associated with negative outcomes including lower quality of life, diminished well-being, and relational distress. For patients undergoing hematopoietic stem cell transplantation (HSCT), the degree to which one holds back from discussing illness-related concerns may be an important determinant of social well-being and health; however, this has not been systematically assessed in this population. The purpose of the present study was to assess the moderating effects of holding back discussion of disease-related concerns on the relationship between health-related symptoms and social well-being in adult patients undergoing HSCT. Seventy autologous (n = 55) and allogeneic (n = 15) HSCT patients completed measures of holding back, social well-being, and health symptoms (i.e., pain, fatigue, sleep problems, cognitive problems) both before and after transplantation (i.e., three months after transplantation and six months after transplantation). In patients with average to high levels of holding back, health symptoms were significantly related to lower levels of social well-being; however, for patients with low levels of holding back, the relationship between health symptoms and social well-being was not significant. The results of the present study suggest that the level of holding back may be important in understanding how health-related symptoms relate to social well-being in patients undergoing HSCT. These findings underscore the importance of addressing how patients undergoing HSCT communicate about their disease with others as this may be related to their adjustment to illness and treatment.

Objectives To investigate the prevalence of multimorbidity in adults with intellectual disabilities with and without Down syndrome. Design Large, population-based cross-sectional study. Setting The geographical area of one Health Board, Scotland. Participants All adults (aged 16+ years) known to general practitioners to have intellectual disabilities and adults receiving services provided or paid by intellectual disabilities health or social work services. 1023/1562 potential participants took part (65.5%); 562 (54.9%) men and 461 (45.1%) women, aged 43.9 years (16–83 years). 186 had Down syndrome and 837 did not. Main outcome measures The prevalence of International Statistical Classification of Diseases, 10th revision, physical health conditions and multimorbidity detected at a comprehensive health assessment. Results The mean number of physical health conditions/participant was 11.04, and 98.7% had multimorbidity. The most prevalent conditions are painful and/or disabling and, in some cases, life threatening. The five most prevalent were visual impairment, obesity, epilepsy, constipation and ataxic/gait disorders. The pattern of multimorbidity differs from that seen in the general population and is spread across the entire adult life course. The extent of multimorbidity in the adults with Down syndrome was similar to that of the adults without Down syndrome, while the prevalence of individual conditions differed. Conclusions This robustly designed study with a large population found an extremely high prevalence of multimorbidity in adults with intellectual disabilities across the entire adult life course. This increases complexity of medical management that secondary healthcare services and medical education are not yet geared towards, as these tend to focus on single conditions. This is in addition to complexity due to limitations in communication and understanding. As the physical conditions within their multimorbidity also differ from that seen in the older

Autism spectrum conditions (ASC) are frequently associated with motor coordination difficulties. However, no studies have explored the prevalence of dyspraxia in a large sample of individuals with and without ASC or associations between dyspraxia and autistic traits in these individuals. Two thousand eight hundred seventy-one adults (with ASC) and 10,706 controls (without ASC) self-reported whether they have been diagnosed with dyspraxia. A subsample of participants then completed the Autism Spectrum Quotient (AQ; 1237 ASC and 6765 controls) and the Empathy Quotient (EQ; 1147 ASC and 6129 controls) online through the Autism Research Centre website. The prevalence of dyspraxia was compared between those with and without ASC. AQ and EQ scores were compared across the four groups: (1) adults with ASC with dyspraxia, (2) adults with ASC without dyspraxia, (3) controls with dyspraxia, and (4) controls without dyspraxia. Adults with ASC were significantly more likely to report a diagnosis of dyspraxia (6.9%) than those without ASC (0.8%). In the ASC group, those with co-morbid diagnosis of dyspraxia did not have significantly different AQ or EQ scores than those without co-morbid dyspraxia. However, in the control group (without ASC), those with dyspraxia had significantly higher AQ and lower EQ scores than those without dyspraxia. Dyspraxia is significantly more prevalent in adults with ASC compared to controls, confirming reports that motor coordination difficulties are significantly more common in this group. Interestingly, in the general population, dyspraxia was associated with significantly higher autistic traits and lower empathy. These results suggest that motor coordination skills are important for effective social skills and empathy.

INNOVATION DEVELOPMENT MANAGEMENT IN VERTICALLY INTEGRATED HOLDING COMPANY

Directory of Open Access Journals (Sweden)

Natalya T. Uspenskaja

2015-01-01

Full Text Available The trend towards production consolidation and integration processes taking place both in the Russian and global economies leads to development of business associations, with a holding company being the most common form inRussiaand around the globe. The evidence in favor of the formation of holding companies is that they can benefit from the scale (bulk purchasing, centralized stuff training; in the global capital and exports markets they can be more effective than smaller businesses and, if non-profitable, a loss-making structure is easier to liquidate than the entire company; holding companies and associations can be an effective defender from political interference. As the importance of the well-functioning and harmonized procedure for the companies’ integration will increase (especially in the context of Russian business, where specific features of many areas of the production system imply the use of holding oligopolies as the most effective form of market structures, there is a need in their more profound study and, in particular, in the analysis of the most important technologies of the general integration procedure. The article outlines the relevance of innovative development management of vertically integrated holding systems, lists principles of innovative activity management and considers the features of innovation management of a vertically integrated holding company. The objective of the research is to study theoretical and practical aspects of innovative development management in vertically integrated holding systems. The object of research is management structures in innovative holding companies. While working on the article, the following methods of economic research were used: abstract and logical method, empirical method, method of expert evaluations, as well as methods of structural and functional and statistical analysis.

Lower conditioning leisure-time physical activity in young adults born preterm at very low birth weight.

Directory of Open Access Journals (Sweden)

Nina Kaseva

Full Text Available BACKGROUND: Adults born preterm at very low birth weight (VLBW, <1500 g have elevated levels of risk factors for cardiovascular diseases and type 2 diabetes. Preliminary observations suggest that this could partly be explained by lower rates of physical activity. The aim of this study was to assess physical activity in healthy young adults born preterm at very low birth weight compared with term-born controls. METHODOLOGY/PRINCIPAL FINDINGS: We studied 94 unimpaired young adults, aged 21-29 years, born at VLBW and 101 age-, sex-, and birth hospital-matched term-born controls from one regional center in Southern Finland. The participants completed a validated 30-item 12-month physical activity questionnaire and the NEO-Personality Inventory based on the Big Five taxonomy, the most commonly used classification of personality traits. Yearly frequency, total time, total volume and energy expenditure of conditioning and non-conditioning leisure-time physical activity (LTPA and commuting physical activity were compared between VLBW and term-born subjects. A subset of participants underwent dual-energy x-ray absorptiometry for body composition measurement. Data were analyzed by multiple linear regression. Compared with controls, VLBW participants had lower frequency [-38.5% (95% CI; -58.9, -7.7], total time [-47.4% (95% CI; -71.2, -4.1], total volume [-44.3% (95% CI; -65.8, -9.2] and energy expenditure [-55.9% (95% CI; -78.6, -9.4] of conditioning LTPA when adjusted for age, sex, body mass index, smoking, parental education and personality traits. Adjusting for lean body mass instead of body mass index attenuated the difference. There were no differences in non-conditioning LTPA or commuting physical activity. CONCLUSIONS/SIGNIFICANCE: Compared with term-born controls, unimpaired VLBW adults undertake less frequent LTPA with lower total time and volume of exercise resulting in lower energy expenditure. Differences in personality that exist between the

Patient-Centred Care of Older Adults With Cardiovascular Disease and Multiple Chronic Conditions.

Science.gov (United States)

Kim, Dae Hyun; Rich, Michael W

2016-09-01

Multimorbidity, defined as the presence of 2 or more chronic conditions, is common among older adults with cardiovascular disease. These individuals are at increased risk for poor health outcomes and account for a large proportion of health care utilization. Clinicians are challenged with the heterogeneity of this population, the complexity of the treatment regimen, limited high-quality evidence, and fragmented health care systems. Each treatment recommended by a clinical practice guideline for a single cardiovascular disease might be rational, but the combination of all evidence-based recommendations can be impractical or even harmful to individuals with multimorbidity. These challenges can be overcome with a patient-centred approach that incorporates the individual's preferences, relevant evidence, the overall and condition-specific prognosis, clinical feasibility of treatments, and interactions with other treatments and coexisting chronic conditions. The ultimate goal is to maximize benefits and minimize harms by optimizing adherence to the most essential treatments, while acknowledging trade-offs between treatments for different health conditions. It might be necessary to discontinue therapies that are not essential or potentially harmful to decrease the risk of drug-drug and drug-disease interactions from polypharmacy. A decision to initiate, withhold, or stop a treatment should be on the basis of the time horizon to benefits vs the individual's prognosis. In this review, we illustrate how cardiologists and general practitioners can adopt a patient-centred approach to focus on the aspects of cardiovascular and noncardiovascular health that have the greatest effect on functioning and quality of life in older adults with cardiovascular disease and multimorbidity.

2012-01-01

Aim: To characterize normal pancreas metabolites using in vivo proton magnetic resonance spectroscopy ( 1 H MRS) at 3 T under conditions of breath-holding and free-breathing. Materials and methods: The pancreases of 32 healthy volunteers were examined using 1 H MRS during breath-holding and free-breathing acquisitions in a single-voxel point-resolved selective spectroscopy sequence (PRESS) technique using a 3 T MRI system. Resonances were compared between paired spectra of the two breathing modes. Furthermore, correlations between lipid (Lip) content and age, body-mass index (BMI), as well as choline (Cho) peak visibility of the normal pancreas were analysed during breath-holding. Results: Twenty-nine pairs of spectra were successfully obtained showing three major resonances, Lip, Cho, cholesterol and the unsaturated parts of the olefinic region of fatty acids (Chol + Unsat). Breath-hold spectra were generally better, with higher signal-to-noise ratios (SNR; Z=–2.646, p = 0.008) and Cho peak visible status (Z=–2.449, p = 0.014). Correlations were significant between spectra acquired by the two breathing modes, especially for Lip height, Lip area, and the area of other peaks at 1.9–4.1 ppm. However, the Lip resonance was significantly different between the spectra of the two breathing modes (p 1 H MRS of the normal pancreas at 3 T is technically feasible and can characterize several metabolites. 1 H MRS during breath-holding acquisition is superior to that during free-breathing acquisition.

Lodging of a constitutional complaint. Reason: Inhibition to hold a demonstration

International Nuclear Information System (INIS)

Anon.

1986-01-01

The Federal Consitutional Court states the conditions allowing issue of a preliminary order of court - in this case, for reinstating the suspensive effect of a protest lodged against an inhibition to hold a demonstration, i.e. for allowing the demonstration to be held - in the event that due to lack of time the Federal Constitutional Court is not in a position to sufficiently clarify the state of facts. The constitutional complaint and petition for preliminary order had been filed at the evening before the day the demonstration was planned to be held. Judging from the facts and circumstances given in the notice inhibiting the demonstration, and the conditions stated by the Administrative Court, there is reason enough to presume that holding the demonstration near the building site of the Wackersdorf Reprocessing Plant will very likely lead to endangering public peace and order. Against this background, the Federal Constitutional Court cannot see reasons to deviate from the assessment of facts given in the decision protested against. This all the more as the wording of the attacked decisions is such that it can be assumed that the constitutional principles stated by the Federal Constitutional Court in its Brokdorf decision (of May 14, 1985) have duly been taken into account.

2018-01-23

Depression is the most commonly experienced mental health condition in adults with autism spectrum conditions (ASC). However, it is unclear what tools are currently being used to assess depression in ASC, or whether tools need to be adapted for this group. This systematic review therefore aimed to identify tools used to assess depression in adults with and without ASC, and then evaluate these tools for their appropriateness and measurement properties. Medline, PsychINFO and Web of Knowledge were searched for studies of depression in: (a) adults with ASC, without co-morbid intellectual disability; and (b) adults from the general population without co-morbid conditions. Articles examining the measurement properties of these tools were then searched for using a methodological filter in PubMed, and the quality of the evidence was evaluated using the COSMIN checklist. Twelve articles were identified which utilized three tools to assess depression in adults with ASC, but only one article which assessed the measurement properties of one of these tools was identified and thus evaluated. Sixty-four articles were identified which utilized five tools to assess depression in general population adults, and fourteen articles had assessed the measurement properties of these tools. Overall, two tools were found to be robust in their measurement properties in the general population-the Beck Depression Inventory (BDI-II), and the patient health questionnaire (PHQ-9). Crucially only one study was identified from the COSMIN search, which showed weak evidence in support of the measurement properties of the BDI-II in an ASC sample. Implications for effective measurement of depression in ASC are discussed.

Full Text Available When transnational enterprises set subsidiary companies in certain area, their major aim is to invest indirectly through the holding companies which hold invested share. Especially, because of the geographical neighborhood and economic integration, investing by holding companies is common in Europe. In Europe, taking full advantage of holding company is out of the following two reasons. Firstly, the efficiency and flexibility of the manage strategy of a group could be elevated by making full use of the holding company. Secondly, the transnational enterprises have the possibility of flexible management at the tax strategy level. Recently, the Korean companies are making the best use of holding companies when they are Marching into the EU. In the year 1996, group K purchased 8 enterprises of a certain industry section of B, a German company, setting holding companies in Germany. The analysis result of the case shows that the manage efficiency could be risen and the taxation could be reduced by way of making use of holding companies. As to the Korean investment efficiency of overseas indirect investment in EU, this thesis brought forward a blueprint about integrating the local companies.

In this paper, we use data for Chinese listed companies holding non-listed financial companies over a ten-year period to construct two networks: a two-mode primitive network in which listed companies and non-listed financial companies are considered actors and events, respectively, and a one-mode network that is constructed based on the decreasing-mode method in which listed companies are considered nodes. We analyze the evolution of the listed company co-holding network from several perspectives, including that of the whole network, of information control ability, of implicit relationships, of community division and of small-world characteristics. The results of the analysis indicate that (1) China's developing stock market affects the share-holding condition of listed companies holding non-listed financial companies; (2) the information control ability of co-holding networks is focused on a few listed companies and the implicit relationship of investment preference between listed companies is determined by the co-holding behavior; (3) the community division of the co-holding network is increasingly obvious, as determined by the investment preferences among listed companies; and (4) the small-world characteristics of the co-holding network are increasingly obvious, resulting in reduced communication costs. In this paper, we conduct an evolution analysis and develop an understanding of the factors that influence the listed companies co-holding network. This study will help illuminate research on evolution analysis.

The water holding capacity of bark in Danish angiosperm trees

DEFF Research Database (Denmark)

Larsen, Hanne Marie Ellegård; Rasmussen, Hanne Nina; Nord-Larsen, Thomas

The water holding capacity of bark in seven Danish angiosperm trees was examined. The aim of the study was (1) to examine height trends and (2) bark thickness trends in relation to the water holding capacity and (3) to determine interspecific differences. The wet-weight and dry-weight of a total...... number of 427 bark samples were measured. The water holding capacity was calculated as the difference between wet-weight and dry-weight per wet-weight. The water holding capacity increased with elevation in most tree species and contrary to the expectation, thinner bark generally had a higher water...... holding capacity. Differences in the water holding capacity of bark may influence the occurrence and distribution of a wide range of bark-living organisms including the distribution of corticolous lichens....

PLD-Repair after ''holding'' of rodent cell cultures: A critical annotation

International Nuclear Information System (INIS)

Stevenson, A.F.G.; Lange, C.S.

1987-01-01

The radiosensitivity of cells in vitro has been reported to be influenced by culture-conditions both before and after exposure to ionising radiations. The effect of ''Stationary-Holding'' and/or delayed plating on the repair of potentially lethal damage (PLDR) are such examples. The so-called Stationary or Plateau-Phase of commonly used cell lines like the V79 are often quiescent (non-mitotic). The authors analysis of the V79 ''Plateau-Phase'' (S-phase cytocide through VrUdR incorporation with FuDR block and light exposure) reveals that the cultures have merely reached a state of maximal permissible density and are, in fact, in kinetic equilibrium with at least half the population of cells, even in densely confluent cultures, going through cycle. Attempts at holding the cells from cycling (through nutrient-depletion and serum-privation) were unsuccessful, although the turn-over-rate was reduced. Their assays for X-irradiated clonogenic survivors after attempted holding combined with delayed plating (DP) showed differences in the survival curves for exponentially growing (Log) and confluent cultures, Although DP improved survival in general, it abolished the shoulder in Log cultures. These observations may explain why most PLDR is seen in the second and lower survival-decades. The significance of the persistent cycling fraction in the interpretation of PLDR after delayed plating must be considered

Effect of tensile holds on the deformation behaviour of a nickel base superalloy subjected to low cycle fatigue

The deformation behaviour of the wrought nickel base superalloy EI698 VD has been investigated in conditions of low cycle fatigue. The tensile hold periods, imposing a constant stress into the fatigue loading, have been introduced at the maximum stress value. The individual hold periods were in the range of 1 minute to 10 hours. The fatigue tests were of tension-tension type defined by a stress ratio R = 0.027 and were conducted at temperature of 650 C. The tests were performed until fracture. The time to failure, the time to failure corresponding to total load at peak amplitude and the number of cycles to failure have been criteria to evaluate the deformation behaviour of the alloy subjected to complex cyclic creep loading. In order to predict lifetime of alloy, regarding the respective types cyclic test, the Kitagawa's modified the linear cumulative damage criterion has been considered. The two regression functions for applied hold period interval were proposed time to calculate the time to failure. The formulae can be used to predict the life of nickel base superalloy considering the specific conditions of low cycle fatigue with tensile hold period introduced at stress amplitude peaks. The failure analysis of fracture surfaces contributed to evaluation of the role of repeatedly reduced stress in damage process. (orig.)

SU-E-J-62: Breath Hold for Left-Sided Breast Cancer: Visually Monitored Deep Inspiration Breath Hold Amplitude Evaluated Using Real-Time Position Management

2015-06-15

Purpose: We used Real-Time Position Management (RPM) to evaluate breath hold amplitude and variability when gating with a visually monitored deep inspiration breath hold technique (VM-DIBH) with retrospective cine image chest wall position verification. Methods: Ten patients with left-sided breast cancer were treated using VM-DIBH. Respiratory motion was passively collected once weekly using RPM with the marker block positioned at the xiphoid process. Cine images on the tangent medial field were acquired on fractions with RPM monitoring for retrospective verification of chest wall position during breath hold. The amplitude and duration of all breath holds on which treatment beams were delivered were extracted from the RPM traces. Breath hold position coverage was evaluated for symmetric RPM gating windows from ± 1 to 5 mm centered on the average breath hold amplitude of the first measured fraction as a baseline. Results: The average (range) breath hold amplitude and duration was 18 mm (3–36 mm) and 19 s (7–34 s). The average (range) of amplitude standard deviation per patient over all breath holds was 2.7 mm (1.2–5.7 mm). With the largest allowable RPM gating window (± 5 mm), 4 of 10 VM-DIBH patients would have had ≥ 10% of their breath hold positions excluded by RPM. Cine verification of the chest wall position during the medial tangent field showed that the chest wall was greater than 5 mm from the baseline in only 1 out of 4 excluded patients. Cine images verify the chest wall/breast position only, whether this variation is acceptable in terms of heart sparing is a subject of future investigation. Conclusion: VM-DIBH allows for greater breath hold amplitude variability than using a 5 mm gating window with RPM, while maintaining chest wall positioning accuracy within 5 mm for the majority of patients.

Cash Holdings and Mutual Fund Performance

Cash holdings of equity mutual funds impose a drag on fund performance but also allow managers to make quick investments in attractive stocks and satisfy outflows without costly fire sales. This article shows that actively managed equity funds with high abnormal cash—that is, with cash holdings in excess of the level predicted by fund attributes—outperform their low abnormal cash peers by over 2% per year. Managers carrying high abnormal cash compensate for the low return on cash by making su...

In tip-scan atomic force microscopy (AFM) that scans a cantilever chip in the three dimensions, the chip body is held on the Z-scanner with a holder. However, this holding is not easy for high-speed (HS) AFM because the holder that should have a small mass has to be able to clamp the cantilever chip firmly without deteriorating the Z-scanner’s fast performance, and because repeated exchange of cantilever chips should not damage the Z-scanner. This is one of the reasons that tip-scan HS-AFM has not been established, despite its advantages over sample stage-scan HS-AFM. Here, we present a novel method of cantilever chip holding which meets all conditions required for tip-scan HS-AFM. The superior performance of this novel chip holding mechanism is demonstrated by imaging of the α{sub 3}β{sub 3} subcomplex of F{sub 1}-ATPase in dynamic action at ∼7 frames/s.

Multiple job holding, local labor markets, and the business cycle

Directory of Open Access Journals (Sweden)

Barry T. Hirsch

2016-04-01

Full Text Available Abstract About 5 % of US workers hold multiple jobs, which can exacerbate or mitigate employment changes over the business cycle. Theory is ambiguous and prior literature is not fully conclusive. We examine the relationship between multiple job holding and local unemployment rates using a large Current Population Survey data set of workers in urban labor markets during 1998–2013. Labor markets with high unemployment have moderately lower rates of multiple job holding. Yet no relationship between multiple job holding and unemployment is found within markets over time, with near-zero estimates being precisely estimated. Multiple job holding is largely acyclic.

Cash Holdings Policy: a Dynamic Analysis of Brazilian Companies

Directory of Open Access Journals (Sweden)

Fadwa Muhieddine Dahrouge

2013-09-01

Full Text Available This paper investigates how corporate cash holdings were adjusted over time for Brazilian companies during the crisis of 2008-2009. We adopt a dynamic model of corporate cash holdings to evaluate the main determinants for the speed of adjustment of cash holdings at the optimum level. We find evidence that: a the adjustment costs of Brazilian companies are high implying a delay in reaching the optimum level of cash; b the low speed adjustment to the optimum level is due to the limited availability of credit and the high cost of bank debt; c during crisis, the changes in working capital are positively related to the level of cash holdings providing evidence that companies prefer finance to growth with liquidity; d companies have looked for long-term financing to secure liquidity rather than investing on fixed assets, implying a negative relationship between investment and cash holding.

Reducing Ageism: Education About Aging and Extended Contact With Older Adults.

Science.gov (United States)

Lytle, Ashley; Levy, Sheri R

2017-11-19

Ageism is of increasing concern due to the growing older population worldwide and youth-centered focus of many societies. The current investigation tested the PEACE (Positive Education about Aging and Contact Experiences) model for the first time. Two online experimental studies examined 2 key factors for reducing ageism: education about aging (providing accurate information about aging) and extended contact (knowledge of positive intergenerational contact) as well as their potential combined effect (education plus extended contact). In Study 1, 354 undergraduates in all 3 experimental conditions (vs. control participants) reported less negative attitudes toward older adults (delayed post-test) and greater aging knowledge (immediate and delayed post-tests), when controlling for pre-study attitudes. In Study 2, 505 national community participants (ages 18-59) in all experimental conditions (vs. control participants) reported less negative attitudes toward older adults (immediate post-test) and greater aging knowledge (immediate and delayed post-tests). In summary, across 2 online studies, education about aging and knowledge of intergenerational extended contact improved attitudes toward older adults and aging knowledge. Thus, brief, online ageism-reduction strategies can be an effective way to combat ageism. These strategies hold promise to be tested in other settings, with other samples, and to be elaborated into more in-depth interventions that aim to reduce ageism in everyday culture. © The Author 2017.

Patent holdings of US biotherapeutic companies in major markets.

Science.gov (United States)

Sebastian, Teena E; Yerram, Chandra Bindu; Saberwal, Gayatri

2009-05-01

In previous studies we examined the (United States, US) patent holdings of 109 largely North American biotech companies developing therapeutics that, in particular, have an interest in discovery stage science. There appears little correlation between the number of patents and the number of products of individual companies. Here we quantified and compared the 103 US-headquartered companies' patent holdings in Australia, Canada, Europe, Japan and the US. The companies demonstrate variable and surprising patterns of patent holdings across these countries or regions. For most companies, patent holdings are not in proportion to the importance of the country as a biotech or pharma market. These results have implications for the patenting strategies of small biotech companies involved in drug discovery.

Prenatal Testing for Adult-Onset Conditions: the Position of the National Society of Genetic Counselors.

Science.gov (United States)

Hercher, Laura; Uhlmann, Wendy R; Hoffman, Erin P; Gustafson, Shanna; Chen, Kelly M

2016-12-01

Advances in genetic testing and the availability of such testing in pregnancy allows prospective parents to test their future child for adult-onset conditions. This ability raises several complex ethical issues. Prospective parents have reproductive rights to obtain information about their fetus. This information may or may not alter pregnancy management. These rights can be in conflict with the rights of the future individual, who will be denied the right to elect or decline testing. This paper highlights the complexity of these issues, details discussions that went into the National Society of Genetic Counselors (NSGC) Public Policy Task Force's development of the Prenatal testing for Adult-Onset Conditions position statement adopted in November 2014, and cites relevant literature on this topic through December 2015. Issues addressed include parental rights and autonomy, rights of the future child, the right not to know, possible adverse effects on childhood and the need for genetic counseling. This paper will serve as a reference to genetic counselors and healthcare professionals when faced with this situation in clinical practice.

1999-01-01

In this study, we used magnetic resonance (MR) imaging to measure portal blood flow in 12 healthy controls and 17 cirrhotics while they were breath-holding after inspiration and after expiration. We then compared the results with measurements made during normal respiration in the healthy controls and cirrhotics. Blood flow in the main portal vein under basal fasting conditions was quantitated using the cine phase-contrast MR velocity mapping method. Three measurements were made on one occasion, as follows: throughout the cardiac cycle during normal respiration, with the subject breath-holding after maximal inspiration, and with the subject breath-holding after maximal expiration. During normal respiration, portal blood flow was 1.3±0.2 l/min in controls vs 1.0±0.1 l/min in cirrhotics (P<0.0001); while subjects were breath-holding after inspiration, portal blood flow was 1.0±0.2 l/min in controls vs 0.9±0.1 l/min in cirrhotics; and while subjects were breath-holding after expiration, portal blood flow was 1.5±0.2 l/min in controls vs 1.1±0.2 l/min in cirrhotics (P<0.0001). The differences were primarily due to changes in flow velocity. When the magnitude of these hemodynamic changes in the three respiratory conditions was compared in controls and cirrhotics, analysis of variance (ANOVA) showed a significant difference (P<0.0001). In controls, portal blood flow decreased during maximal inspiration relative to flow during normal respiration (-24.6±8.3%). Changes in portal blood flow in controls were greater than in cirrhotics (-13.5±4.5%) (P<0.0001); however, the difference in blood flow increase associated with maximal expiration between the two groups (+11.8±9.4% vs +5.9±11.5%) was not significant. We found that the respiration-induced hemodynamic variation in portal blood flow was less in cirrhotics than in the healthy controls. Portal blood flow measurements made during normal respiration using MR imaging closely reflect nearly physiologic conditions

2014-04-01

Vulnerability to alcoholism is determined by many factors, including the balance of pleasurable vs. aversive alcohol-induced sensations: pleasurable sensations increase intake, while aversive sensations decrease it. Female sex and adolescent age are associated with lower sensitivity to intake-reducing effects and more rapid development of alcohol abuse. This study assessed voluntary drinking and the aversive effects of alcohol to determine whether these measures are inversely related across the sexes and development. Voluntary drinking of 20 % ethanol in an every-other-day (EOD) availability pattern and the dose-response relationship of ethanol conditioned taste aversion (CTA) were assessed in male and female adolescent and adult rats. CTA was sex specific in adult but not adolescent rats, with adult females exhibiting less aversion. Voluntary ethanol consumption varied according to age and individual differences but was not sex specific. Adolescents initially drank more than adults, exhibited greater day-to-day variation in consumption, were more susceptible to the alcohol deprivation effect, and took longer to establish individual differences in consumption patterns. These results show that the emergence of intake patterns differs between adolescents and adults. Adolescents as a group initiate drinking at high levels but decrease intake as they mature. A subset of adolescents maintained high drinking levels into adulthood. In contrast, most adults consumed at steady, low levels, but a small subset quickly established and maintained high-consumption patterns. Adolescents also showed marked deprivation-induced increases. Sex differences were not observed in EOD drinking during either adolescence or adulthood.

Voluntary Breath-hold Technique for Reducing Heart Dose in Left Breast Radiotherapy

Breath-holding techniques reduce the amount of radiation received by cardiac structures during tangential-field left breast radiotherapy. With these techniques, patients hold their breath while radiotherapy is delivered, pushing the heart down and away from the radiotherapy field. Despite clear dosimetric benefits, these techniques are not yet in widespread use. One reason for this is that commercially available solutions require specialist equipment, necessitating not only significant capital investment, but often also incurring ongoing costs such as a need for daily disposable mouthpieces. The voluntary breath-hold technique described here does not require any additional specialist equipment. All breath-holding techniques require a surrogate to monitor breath-hold consistency and whether breath-hold is maintained. Voluntary breath-hold uses the distance moved by the anterior and lateral reference marks (tattoos) away from the treatment room lasers in breath-hold to monitor consistency at CT-planning and treatment setup. Light fields are then used to monitor breath-hold consistency prior to and during radiotherapy delivery. PMID:25046661

Effect of holding office on the behavior of politicians.

Enemark, Daniel; Gibson, Clark C; McCubbins, Mathew D; Seim, Brigitte

2016-11-29

Reciprocity is central to our understanding of politics. Most political exchanges-whether they involve legislative vote trading, interbranch bargaining, constituent service, or even the corrupt exchange of public resources for private wealth-require reciprocity. But how does reciprocity arise? Do government officials learn reciprocity while holding office, or do recruitment and selection practices favor those who already adhere to a norm of reciprocity? We recruit Zambian politicians who narrowly won or lost a previous election to play behavioral games that provide a measure of reciprocity. This combination of regression discontinuity and experimental designs allows us to estimate the effect of holding office on behavior. We find that holding office increases adherence to the norm of reciprocity. This study identifies causal effects of holding office on politicians' behavior.

Trunk muscle fatigue during a lateral isometric hold test: what are we evaluating?

2012-04-01

Full Text Available Abstract Background Side bridge endurance protocols have been suggested to evaluate lateral trunk flexor and/or spine stabilizer muscles. To date, no study has investigated muscle recruitment and fatigability during these protocols. Therefore the purpose of our study was to quantify fatigue parameters in various trunk muscles during a modified side bridge endurance task (i.e. a lateral isometric hold test on a 45° roman chair apparatus and determine which primary trunk muscles get fatigued during this task. It was hypothesized that the ipsilateral external oblique and lumbar erector spinae muscles will exhibit the highest fatigue indices. Methods Twenty-two healthy subjects participated in this study. The experimental session included left and right lateral isometric hold tasks preceded and followed by 3 maximal voluntary contractions in the same position. Surface electromyography (EMG recordings were obtained bilaterally from the external oblique, rectus abdominis, and L2 and L5 erector spinae. Statistical analysis were conducted to compare the right and left maximal voluntary contractions (MVC, surface EMG activities, right vs. left holding times and decay rate of the median frequency as the percent change from the initial value (NMFslope. Results No significant left and right lateral isometric hold tests differences were observed neither for holding times (97.2 ± 21.5 sec and 96.7 ± 24.9 sec respectively nor for pre and post fatigue root mean square during MVCs. However, participants showed significant decreases of MVCs between pre and post fatigue measurements for both the left and right lateral isometric hold tests. Statistical analysis showed that a significantly NMFslope of the ipsilateral external oblique during both conditions, and a NMFslope of the contralateral L5 erector spinae during the left lateral isometric hold test were steeper than those of the other side’s respective muscles.

Nahin, Richard L.; Stussman, Barbara J.; Herman, Patricia M.

2015-01-01

National surveys suggest that millions of adults in the United States use complementary health approaches such as acupuncture, chiropractic manipulation, and herbal medicines to manage painful conditions such as arthritis, back pain and fibromyalgia. Yet, national and per person out-of-pocket (OOP) costs attributable to this condition-specific use are unknown. In the 2007 National Health Interview Survey, use of complementary health approaches, reasons for this use, and associated OOP costs were captured in a nationally representative sample of 5,467 adults. Ordinary least square regression models that controlled for co-morbid conditions were used to estimate aggregate and per person OOP costs associated with 14 painful health conditions. Individuals using complementary approaches spent a total of $14.9 billion (S.E. $0.9 billion) OOP on these approaches to manage these painful conditions. Total OOP expenditures seen in those using complementary approaches for their back pain ($8.7 billion, S.E. $0.8 billion) far outstripped that of any other condition, with the majority of these costs ($4.7 billion, S.E. $0.4 billion) resulting from visits to complementary providers. Annual condition-specific per-person OOP costs varied from a low of $568 (SE $144) for regular headaches, to a high of $895 (SE $163) for fibromyalgia. PMID:26320946

Radiation Dose Estimates in Indian Adults in Normal and Pathological Conditions due to 99Tcm-Labelled Radiopharmaceuticals

International Nuclear Information System (INIS)

Tyagi, K.; Jain, S.C.; Jain, P.C.

2001-01-01

ICRP Publications 53, 62 and 80 give organ dose coefficients and effective doses to ICRP Reference Man and Child from established nuclear medicine procedures. However, an average Indian adult differs significantly from the ICRP Reference Man as regards anatomical, physiological and metabolic characteristics, and is also considered to have different tissue weighting factors (called here risk factors). The masses of total body and most organs are significantly lower for the Indian adult than for his ICRP counterpart (e.g. body mass 52 and 70 kg respectively). Similarly, the risk factors are lower by 20-30% for 8 out of the 13 organs and 30-60% higher for 3 organs. In the present study, available anatomical data of Indians and their risk factors have been utilised to estimate the radiation doses from administration of commonly used 99 Tc m -labelled radiopharmaceuticals under normal and certain pathological conditions. The following pathological conditions have been considered for phosphates/phosphonates - high bone uptake and severely impaired kidney function; IDA - parenchymal liver disease, occlusion of cystic duct, and occlusion of bile duct; DTPA - abnormal renal function; large colloids - early to intermediate diffuse parenchymal liver disease, intermediate to advanced parenchymal liver disease; small colloids - early to intermediate parenchymal liver disease, intermediate to advanced parenchymal liver disease; and MAG3 - abnormal renal function, acute unilateral renal blockage. The estimated 'effective doses' to Indian adults are 14-21% greater than the ICRP value from administration of the same activity of radiopharmaceutical under normal physiological conditions based on anatomical considerations alone, because of the smaller organ masses for the Indian; for some pathological conditions the effective doses are 11-22% more. When tissue risk factors are considered in addition to anatomical considerations, the estimated effective doses are still found to be

Intangible Capital and Corporate Cash Holdings: Theory and Evidence

The rise in intangible capital is a fundamental driver of the secular trend in US corporate cash holdings over the last decades. We construct a new measure of intangible capital and show that intangible capital is the most important firm-level determinant of corporate cash holdings. Our measure accounts for almost as much of the secular increase in cash since the 1980s as all other standard determinants together. We then develop a new model of corporate cash holdings that introduces intangibl...

Enemark, Daniel; Gibson, Clark C.; McCubbins, Mathew D.; Seim, Brigitte

2016-01-01

Reciprocity is central to our understanding of politics. Most political exchanges—whether they involve legislative vote trading, interbranch bargaining, constituent service, or even the corrupt exchange of public resources for private wealth—require reciprocity. But how does reciprocity arise? Do government officials learn reciprocity while holding office, or do recruitment and selection practices favor those who already adhere to a norm of reciprocity? We recruit Zambian politicians who narrowly won or lost a previous election to play behavioral games that provide a measure of reciprocity. This combination of regression discontinuity and experimental designs allows us to estimate the effect of holding office on behavior. We find that holding office increases adherence to the norm of reciprocity. This study identifies causal effects of holding office on politicians’ behavior. PMID:27856736

Methamphetamine (MAP) addiction is substantially prevalent in today's society, resulting in thousands of deaths and costing billions of dollars annually. Despite the potential deleterious consequences, few studies have examined the long-term effects of embryonic MAP exposure. Using the invertebrate nematode Caenorhabditis elegans allows for a controlled analysis of behavioral and neurochemical changes due to early developmental drug exposure. The objective of the current study was to determine the long-term behavioral and neurochemical effects of embryonic exposure to MAP in C. elegans. In addition, we sought to improve our conditioning and testing procedures by utilizing liquid filtration, as opposed to agar, and smaller, 6-well testing plates to increase throughput. Wild-type N2 C. elegans were embryonically exposed to 50 μM MAP. Using classical conditioning, adult-stage C. elegans were conditioned to MAP (17 and 500 μM) in the presence of either sodium ions (Na+) or chloride ions (Cl-) as conditioned stimuli (CS+/CS-). Following conditioning, a preference test was performed by placing worms in 6-well test plates spotted with the CS+ and CS- at opposite ends of each well. A preference index was determined by counting the number of worms in the CS+ target zone divided by the total number of worms in the CS+ and CS- target zones. A food conditioning experiment was also performed in order to determine whether embryonic MAP exposure affected food conditioning behavior. For the neurochemical experiments, adult worms that were embryonically exposed to MAP were analyzed for dopamine (DA) content using high-performance liquid chromatography. The liquid filtration conditioning procedure employed here in combination with the use of 6-well test plates significantly decreased the time required to perform these experiments and ultimately increased throughput. The MAP conditioning data found that pairing an ion with MAP at 17 or 500 μM significantly increased the preference

Full Text Available Concentration and cooperation belong to the main attributes of the modern business life. Business competition makes the start of a new business more difficult. Just the moment of concentration and cooperation can make the break to the new business easier. This can be achieved by including new businesses into holding companies. Basically there are two ways how to do a business. These depend on whether company carries out many lines of business or on the amount of asset. The first way is to cover everything with one enterprise and thus to create one accounting unit. The second way is based on a foundation of a holding structure with subsidiaries and the holder on the top. In fact holding is a specific way how to cover business by many subsidiaries.The goal of this article is to describe specifics of a financial management of holdings when managing cash-flow. The focus is on reasons of holding structure and usage of both theoretical and other models of managing cash such as Baumol model, Miller-Orr model and Beránek model. As transfers within the holding organization belong to the main advantageous of holding, the way how to transfer finance from one subsidiary to other or from subsidiary to holder or reversely is handled here.

Full Text Available We analyze food-item level data collected from 50 adults from the United States using the Remote Food Photography Method® to provide the first estimates of plate waste gathered from adults across multiple consecutive meals and days in free-living conditions, and during laboratory-based meals with fixed food items and quantities. We find average plate waste in free-living conditions is 5.6 grams (7.7 kcals per item and that 3.3% of all food selected is returned as plate waste, where the percent waste figure is substantially lower than previously published plate waste estimates gathered primarily from dine-out settings in the United States such as buffets and institutional settings with limited-choice meals (e.g., school cafeterias. Plate waste from the same participants during the laboratory-based meals is significantly higher with an average of 203.2 grams of solid plate waste per meal (531.3 kcals or 39.1% of the food provided, which is similar to the plate waste percentages found reported in some school cafeteria settings. The amount of plate waste generated in free-living conditions is significantly positively associated with portion size selected for an item. In a multivariate analysis that controls for macronutrient profile, items selected from the vegetables, fats/oils/dressings, and grains categories are associated with significantly greater amounts of plate waste per item. We find no significant associations between free-living plate waste and gender, age, race or body mass index but find that women leave more plate waste in the lab meal where portion sizes are pre-determined by the researcher and similar for all respondents. We discuss possible implications of these findings for programs focused on reducing plate waste and food waste among consumers.

2006-01-01

U.S. corporations hold significant amounts of cash on their balance sheets, and these cash holdings have been justified in the existing empirical literature by transaction costs and precautionary motives. An additional explanation, considered in this study, is that U.S. multinational firms hold cash in their foreign subsidiaries because of the tax costs associated with repatriating foreign income. Consistent with this hypothesis, firms that face higher repatriation tax burdens hold higher lev...

Adults with an epilepsy history fare significantly worse on positive mental and physical health than adults with other common chronic conditions-Estimates from the 2010 National Health Interview Survey and Patient Reported Outcome Measurement System (PROMIS) Global Health Scale.

Kobau, Rosemarie; Cui, Wanjun; Zack, Matthew M

2017-07-01

Healthy People 2020, a national health promotion initiative, calls for increasing the proportion of U.S. adults who self-report good or better health. The Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Scale (GHS) was identified as a reliable and valid set of items of self-reported physical and mental health to monitor these two domains across the decade. The purpose of this study was to examine the percentage of adults with an epilepsy history who met the Healthy People 2020 target for self-reported good or better health and to compare these percentages to adults with history of other common chronic conditions. Using the 2010 National Health Interview Survey, we compared and estimated the age-standardized prevalence of reporting good or better physical and mental health among adults with five selected chronic conditions including epilepsy, diabetes, heart disease, cancer, and hypertension. We examined response patterns for physical and mental health scale among adults with these five conditions. The percentages of adults with epilepsy who reported good or better physical health (52%) or mental health (54%) were significantly below the Healthy People 2020 target estimate of 80% for both outcomes. Significantly smaller percentages of adults with an epilepsy history reported good or better physical health than adults with heart disease, cancer, or hypertension. Significantly smaller percentages of adults with an epilepsy history reported good or better mental health than adults with all other four conditions. Health and social service providers can implement and enhance existing evidence-based clinical interventions and public health programs and strategies shown to improve outcomes in epilepsy. These estimates can be used to assess improvements in the Healthy People 2020 Health-Related Quality of Life and Well-Being Objective throughout the decade. Published by Elsevier Inc.

Impact of breath holding on cardiovascular respiratory and cerebrovascular health.

Science.gov (United States)

Dujic, Zeljko; Breskovic, Toni

2012-06-01

Human underwater breath-hold diving is a fascinating example of applied environmental physiology. In combination with swimming, it is one of the most popular forms of summer outdoor physical activities. It is performed by a variety of individuals ranging from elite breath-hold divers, underwater hockey and rugby players, synchronized and sprint swimmers, spear fishermen, sponge harvesters and up to recreational swimmers. Very few data currently exist concerning the influence of regular breath holding on possible health risks such as cerebrovascular, cardiovascular and respiratory diseases. A literature search of the PubMed electronic search engine using keywords 'breath-hold diving' and 'apnoea diving' was performed. This review focuses on recent advances in knowledge regarding possibly harmful physiological changes and/or potential health risks associated with breath-hold diving. Available evidence indicates that deep breath-hold dives can be very dangerous and can cause serious acute health problems such a collapse of the lungs, barotrauma at descent and ascent, pulmonary oedema and alveolar haemorrhage, cardiac arrest, blackouts, nitrogen narcosis, decompression sickness and death. Moreover, even shallow apnoea dives, which are far more frequent, can present a significant health risk. The state of affairs is disturbing as athletes, as well as recreational individuals, practice voluntary apnoea on a regular basis. Long-term health risks of frequent maximal breath holds are at present unknown, but should be addressed in future research. Clearly, further studies are needed to better understand the mechanisms related to the possible development or worsening of different clinical disorders in recreational or competitive breath holding and to determine the potential changes in training/competition regimens in order to prevent these adverse events.

Full Text Available This research aimed to analyze the effect of leverage and asymmetry information on the firm value through cash holding as mediation variable. The populations of this research were all the firms which listed on the Indonesia Stock Exchange since 2012 – 2015. A sample of this research was saturated sample and census, consisted 56 firms related the population criteria.  This research used secondary data from the firm financial report through path analysis method. This research showed that leverage had a negative effect on the cash holdings, asymmetry information had a negative effect on the firm value through cash holding, and cash holding had a negative effect on the firm value.  With leverage and effect on cash, holding cannot affect the firm value, due to investor risk-averse, investor risk seeker, and neutral investor has their own point of view in assessing the company. Cash holdings can lead to asymmetric information that can lead to agency conflict that can affect a company's performance, so that indirectly, with the existence of asymmetry information had an effect on the declining the firm value. 

A Hold-down Margin Assessment using Statistical Method for the PWR Fuel Assembly

International Nuclear Information System (INIS)

Jeon, S. Y.; Park, N. K.; Lee, K. S.; Kim, H. K.

2007-01-01

The hold-down springs provide an acceptable hold down force against hydraulic uplift force absorbing the length change of the fuel assembly relative to the space between the upper and lower core plates in PWR. These length changes are mainly due to the thermal expansion, irradiation growth and creep down of the fuel assemblies. There are two kinds of hold-down springs depending on the different design concept of the reactor internals of the PWR in Korea, one is a leaf-type hold down spring for Westinghouse type plants and the other is a coil-type hold-down spring for OPR1000 (Optimized Power Reactor 1000). There are four sets of hold-down springs in each fuel assembly for leaf type hold-down spring and each set of the hold-down springs consists of multiple tapered leaves to form a cantilever leaf spring set. The length, width and thickness of the spring leaves are selected to provide the desired spring constant, deflection range, and hold down force. There are four coil springs in each fuel assembly for coil-type hold-down spring. In this study, the hold-down forces and margins were calculated for the leaf-type and coil-type hold-down springs considering geometrical data of the fuel assembly and its components, length changes of the fuel assembly due to thermal expansion, irradiation growth, creep, and irradiation relaxation. The hold-down spring forces were calculated deterministically and statistically to investigate the benefit of the statistical calculation method in view of hold-down margin. The Monte-Carlo simulation method was used for the statistical hold down force calculation

In this study, whether physical activity is independently associated with direct healthcare costs in community-dwelling older adults with multiple chronic conditions was examined. Cross-sectional analysis. Research laboratory. 299 community-dwelling men and women volunteers aged 65 years and older with chronic conditions. None. Primary dependent variable was direct healthcare costs incurred in the previous 3 months. Participants completed the Health Resource Utilisation (HRU) questionnaire. To estimate HRU, direct costs in the previous 3 months were calculated using the three-party payer perspective of the British Columbia Ministry of Health, deemed representative of the Canadian healthcare system costs. For medications, the Retail Pharmacy Dispensed prescription cost tables were used. Primary independent variables were (1) self-report current level of physical activity as assessed by the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) and (2) general balance and mobility as assessed by the National Institute on Aging Balance Scale. The mean number of chronic conditions per participant was six. Current level of physical activity was independently and inversely associated with HRU. Age, sex, number of chronic conditions, global cognitive function, body mass index, and general balance and mobility together accounted for 24.3% of the total variance. Adding the PASIPD score resulted in an R2 change of 3.3% and significantly improved the model. The total variance accounted by the final model was 27.6%. Physical activity promotion may reduce healthcare costs in older adults with chronic conditions.

Vaidya, V A; Vadodaria, K C; Jha, S

2007-10-01

The evidence that new neuron addition takes place in the mammalian brain throughout adult life has dramatically altered our perspective of the potential for plasticity in the adult CNS. Although several recent reports suggest a latent neurogenic capacity in multiple brain regions, the two major neurogenic niches that retain the ability to generate substantial numbers of new neurons in adult life are the subventricular zone (SVZ) lining the lateral ventricles and the subgranular zone (SGZ) in the hippocampal formation. The discovery of adult neurogenesis has also unveiled a novel therapeutic target for the repair of damaged neuronal circuits. In this regard, understanding the endogenous mechanisms that regulate adult neurogenesis holds promise both for a deeper understanding of this form of structural plasticity, as well as the identification of pathways that can serve as therapeutic targets to manipulate adult neurogenesis. The purpose of the present review is to discuss the regulation of adult neurogenesis by neurotransmitters and to highlight the relevance of these endogenous regulators as targets to modulate adult neurogenesis in a clinical context.

To prioritize research topics relevant to the care of the growing population of older adults with multiple chronic conditions (MCCs). Survey of experts in MCC practice, research, and policy. Topics were derived from white papers, funding announcements, or funded research projects relating to older adults with MCCs. Survey conducted through the Health Care Systems Research Network (HCSRN) and Claude D. Pepper Older Americans Independence Centers (OAICs) Advancing Geriatrics Infrastructure and Network Growth Initiative, a joint endeavor of the HCSRN and OAICs. Individuals affiliated with the HCSRN or OAICs and national MCC experts, including individuals affiliated with funding agencies having MCC-related grant portfolios. A "top box" methodology was used, counting the number of respondents selecting the top response on a 5-point Likert scale and dividing by the total number of responses to calculate a top box percentage for each of 37 topics. The highest-ranked research topics relevant to the health and healthcare of older adults with MCCs were health-related quality of life in older adults with MCCs; development of assessment tools (to assess, e.g., symptom burden, quality of life, function); interactions between medications, disease processes, and health outcomes; disability; implementation of novel (and scalable) models of care; association between clusters of chronic conditions and clinical, financial, and social outcomes; role of caregivers; symptom burden; shared decision-making to enhance care planning; and tools to improve clinical decision-making. Study findings serve to inform the development of a comprehensive research agenda to address the challenges relating to the care of this "high-need, high-cost" population and the healthcare delivery systems responsible for serving it. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

2016-12-01

Full Text Available Adults with mental health conditions (MHC are especially likely to smoke and experience tobacco-related health disparities. Individuals with MHC may also use electronic nicotine delivery devices (ENDS at disproportionately high rates. However, there is a relative dearth of knowledge regarding ENDS use among individuals with MHC. In a large representative sample of U.S. adults (n = 6051, associations between self-reported MHC diagnoses and ENDS use and susceptibility were examined, stratified by smoking status. Participants with MHC were approximately 1.5 times more likely to have used ENDS in their lifetime and almost twice as likely to currently use ENDS as those without MHC. MHC status was most strongly linked to higher ENDS use among former smokers, and former smokers with MHC were more likely to report using ENDS during past smoking quit attempts than those without MHC. Among participants who had not tried ENDS, former smokers with MHC were especially susceptible to future ENDS use. The potential advantage of ENDS for cessation purposes should be balanced with the risk of attracting former smokers with MHC to ENDS.

Resolving conflicts in task demands during balance recovery: does holding an object inhibit compensatory grasping?

Bateni, Hamid; Zecevic, Aleksandra; McIlroy, William E; Maki, Brian E

2004-07-01

The ability to reach and "grasp" (grip or touch) structures for support in reaction to instability is an important element of the postural repertoire. It is unclear, however, how the central nervous system (CNS) resolves the potential conflict between holding an object and the need to release the held object and grasp alternative support, particularly if the held object is perceived to be relevant to the task of stabilizing the body, e.g. an assistive device. This study examined whether compensatory grasping is inhibited when holding an object, and whether the influence differs when holding an assistive device (cane) versus a task-irrelevant object (top handle portion of a cane). We also investigated the influence of preloading the assistive device, to determine whether conflicting demands for arm-muscle activation (requiring disengagement of ongoing agonist or antagonist activity) would influence the inhibition of compensatory grasping. Unpredictable forward and backward platform translations were used to evoke the balancing reactions in 16 healthy young adults. A handrail was mounted to the right and foot motion was constrained by barriers, with the intent that successful balance recovery would (in large-perturbation trials) require subjects to release the held object and contact the rail with the right hand. Results showed that grasping reactions were commonly used to recover equilibrium when the hand was free (rail contact in 71% of large-perturbation trials). However, holding either the cane or canetop had a potent modulating effect: although early biceps activation was almost never inhibited completely (significant activity within 200 ms in 98% of trials), the average activation amplitude was attenuated by 30-64% and the average frequency of handrail contact was reduced by a factor of two or more. This reduced use of the rail occurred even though the consequence often involved falling against a safety harness or barriers. Handrail contact occurred least

Full Text Available Abstract Background Cardiac iron overload is the leading cause of death in thalassemia major and is usually assessed using myocardial T2* measurements. Recently a cardiovascular magnetic resonance (CMR breath-hold T2 sequence has been developed as a possible alternative. This cardiac T2 technique has good interstudy reproducibility, but its transferability to different centres has not yet been investigated. Methods and Results The breath-hold black blood spin echo T2 sequence was installed and validated on 1.5T Siemens MR scanners at 4 different centres across the world. Using this sequence, 5–10 thalassemia patients from each centre were scanned twice locally within a week for local interstudy reproducibility (n = 34 and all were rescanned within one month at the standardization centre in London (intersite reproducibility. The local interstudy reproducibility (coefficient of variance and mean difference were 4.4% and -0.06 ms. The intersite reproducibility and mean difference between scanners were 5.2% and -0.07 ms. Conclusion The breath-hold myocardial T2 technique is transferable between Siemens scanners with good intersite and local interstudy reproducibility. This technique may have value in the diagnosis and management of patients with iron overload conditions such as thalassemia.

Full Text Available "n  "n  "nObjective: "nIn geriatric practice, the impact of psychological distress on health status has been undermined due to ageism, atypical presentation and less tendency to report negative affect among elderly people. Few studies have examined the impact of psychological stressors on medical burden in older adults. The current study has investigated the correlation of psychological distress and burden of medical conditions in a sample of older people .     "n  "n  "nMethod: A convenient study sample of 120 elderly subjects was recruited from the places where there was greater chance for the elderly people to attend. Data were collected by a trained research assistant using perceived stress scale, cumulative illness rating scale, geriatric depressive scale and a demographic questionnaire.     "n  "n  "nResults: "nOur participants perceived more level of stress than the average for their age. In the current study, the burden of medical condition was significantly correlated with the level of perceived stress(r = .197, p = .044. Moreover, in regression analysis, perceived stress was the strongest predictor for physical health morbidity (R2 =.049, significant f= .03.     "n  "n  "nConclusions: "nThe result of this study suggested that the psychological stressors contribute to poor health outcome in older adults ; the area that is usually overlooked due to ageism and its physiological related changes.

Preservation and hold time of radionuclides must account for both nuclear half-lives and nonnuclear loss mechanisms, but variations in the latter are often neglected. Metals-based defaults are inappropriate for long-lived non-metals C-14 and I-129, which are vulnerable to chemical and biological volatilization. Non-acidification is already widely practiced for them. Recommended addition measures from radiological and chemical literature include glass containers where possible, water filtration where possible, headspace minimization, light shielding, cold (4°C) storage and unfiltered water hold time of 28 days. Soil hold time may need to be shortened when water-logged, excessively sandy, or still adjusting to significant new contamination.

There is limited information that accounts for comorbidity on the impact of role disability associated with a wide range of mental and physical disorders in population-based samples. To estimate the comparative effects of common mental and physical conditions on role disability in the general population using a novel method that accounts for comorbidity. Direct interviews about physical and mental conditions during the past year. The National Comorbidity Survey Replication, a nationally representative series of face-to-face interviews. A nationally representative sample of adults living in households (N = 5962 respondents, 18 years and older). Disability in major life roles was assessed with the World Health Organization Disability Assessment Schedule. Simulations that allow for complex interactions among conditions were used to estimate the conditions' effects on disability days, when respondents were completely unable to carry out their usual daily activities because of problems with mental or physical health, in the past 12 months. An estimated 53.4% of US adults have 1 or more of the mental or physical conditions assessed in the survey. These respondents report an average 32.1 more role-disability days in the past year than demographically matched controls, equivalent to nearly 3.6 billion days of role disability in the population. Musculoskeletal disorders and major depression had the greatest effects on disability days. Mental conditions accounted for more than half as many disability days as all physical conditions at the population level. Associations of specific conditions with disability decreased substantially after controlling for comorbidity, suggesting that prior studies, which generally did not control for comorbidity, overestimated disease-specific effects. The staggering amount of health-related disability associated with mental and physical conditions should be considered in establishing priorities for the allocation of health care and research

Animal movement poses a great risk for disease transmission between holdings. Heterogeneous contact patterns are known to influence the dynamics of disease transmission and should be included in modeling. Using pig movement data from Sweden as an example, we present a method for quantification of between holding contact probabilities based on different production types. The data contained seven production types: Sow pool center, Sow pool satellite, Farrow-to-finish, Nucleus herd, Piglet producer, Multiplying herd and Fattening herd. The method also estimates how much different production types will determine the contact pattern of holdings that have more than one type. The method is based on Bayesian analysis and uses data from central databases of animal movement. Holdings with different production types are estimated to vary in the frequency of contacts as well as in what type of holding they have contact with, and the direction of the contacts. Movements from Multiplying herds to Sow pool centers, Nucleus herds to other Nucleus herds, Sow pool centers to Sow pool satellites, Sow pool satellites to Sow pool centers and Nucleus herds to Multiplying herds were estimated to be most common relative to the abundance of the production types. We show with a simulation study that these contact patterns may also be expected to result in substantial differences in disease transmission via animal movements, depending on the index holding. Simulating transmission for a 1 year period showed that the median number of infected holdings was 1 (i.e. only the index holding infected) if the infection started at a Fattening herd and 2161 if the infection started on a Nucleus herd. We conclude that it is valuable to include production types in models of disease transmission and the method presented in this paper may be used for such models when appropriate data is available. We also argue that keeping records of production types is of great value since it may be helpful in risk

Puerto Rico is experiencing an economic and healthcare crisis, yet there are scarce recent and comprehensive reports on the population's health profile. We aimed to describe prevalent risk factors and health conditions of adults living in Puerto Rico and assess their interrelationship. Participants (n = 380) aged 30-75y recruited from a 2015 convenience sample in primary care clinics in the San Juan, Puerto Rico metropolitan area answered cross-sectional interviewer-administered questionnaires on sociodemographic characteristics, lifestyle behaviors, self-reported medically-diagnosed diseases, health services, and psychosocial factors. Anthropometric measures were obtained. Logistic regression models assessed factors associated with having ≥2 cardiometabolic conditions or ≥ 2 chronic diseases. Most participants had completed ≥college education (57%), had household income diabetes (21%). Higher odds of having ≥2 cardiometabolic conditions (37%) was observed among participants aged ≥50y, with sedentary physical activity, and self-rated fair/poor diet. Odds of having ≥2 chronic diseases (62%) were higher among ≥50y, sleeping difficulties, > 2 h/day television, and self-rated fair/poor diet. Participants obtained (79%) and trusted (92%) health information from physicians. While most participants with a cardiometabolic condition reported receiving medical recommendations on diet (> 73%) and physical activity (> 67%), fewer followed them ( 73%). Participants following medical recommendations were more likely to report healthy vs. poor behaviors (90% vs. 75%, self-rated diet); (73% vs. 56%, physical activity). Adults living in Puerto Rico have multiple lifestyles risk factors and high prevalence of chronic diseases, namely cardiometabolic and psychological conditions. Comprehensive epidemiological studies are needed to identify contributors to chronic disease, including lifestyle behaviors. Concerted multi-level public health and clinical

Full Text Available To evaluate the influence of the skin aging critical level on the adult skin epidermal functional state, an improved analytical method based on the skin surface energetic measurement (TVS modeling was developed. Tenskinmetric measurements were carried out non-invasively in controlled conditions by contact angle method using only a water-drop as reference standard liquid. Adult skin was monitored by TVS Observatory according to a specific and controlled thermal protocol (Camianta protocol in use at the interconnected “Mamma Margherita Terme spa” of Terme Euganee. From June to November 2013, the surface free energy and the epidermal hydration level of adult skin were evaluated on arrival of 265 male and 569 female adult volunteers (51–90 years of age and when they departed 2 weeks later. Sensitive measurements were carried out at 0.1 mN/m. High test compliance was obtained (93.2% of all guests. Very interesting results are obtained. The high sensitivity and discrimination power of tenskinmetry combined with a thermal Camianta protocol demonstrate the possibility to evaluate at baseline level the surface energetic changes and the skin reactivity which occurs on adult skin.

Full Text Available ABSTRACT   There are many factors influencing the decision making of investors in holding their possession on security especially common stock. Monetary crisis condition has proved to be able to influence the investors’ attitude in Jakarta Stock Market in investing their capital especially about the long/short of holding a security. This study is conducted based on the differentiation of conclusion/result of study from previous studies about decision to hold security in the long/short term. The aim of this study is to analyze variables influencing holding period of common stock on public firm listed in LQ 45 Index, that are firms generally have good performance assessed based on both market performance and firm fundamental, then analyzing the dominance influencing variable. This study is conducted in Jakarta Stock Exchange with population of stocks listed in LQ 45 index in period of 2000 – 2001 with the total of 64 firms. The Sample Taking Method is purposive sampling with the criteria that the firms at least listed twice in LQ45 index on the study period. The analysis method used to analyze independent variables: spread, market value, variance return, and dividend pay out ratio and dependent variable: holding period is two stage least squares multiple regression model,  since there is possibility that the correlation of bid-ask spread from the current period and bid-ask spread and holding period from the previous period for every stock take place simultaneously. Results of the study showed that, partially, bid-ask spread variable that constitutes the different value between the highest price provided paid by buyer with the lowest price offered by seller has significance positive correlation on holding period of common stock and there is inverse correlation/significance negative between variance return variable that reflect the risk rate from stock effected by fluctuation of stock price and holding period of common stock.

2014-01-01

The decline of desert bighorn sheep on the Kofa National Wildlife Refuge (KNWR) beginning in 2003 stimulated efforts to determine the factors limiting survival and recruitment. We 1) determined pregnancy rates, body fat, and estimated survival rates of adults and lambs; 2) investigated the relationship between precipitation, forage conditions, previous year’s reproductive success, and adult body condition; 3) assessed the relative influence of body condition of adult females, precipitation, and forage characteristics on apparent survival of lambs; and 4) determined the prevalence of disease. To assess the influence of potential limiting factors on female desert bighorn sheep on the KNWR, we modeled percent body fat of adult females as a function of previous year’s reproductive effort, age class, and forage conditions (i.e., seasonal NDVI and seasonal precipitation). In addition, we assessed the relative influence of the body condition of adult females, precipitation, and forage conditions (NDVI) on length of time a lamb was observed at heel.Adult female survival was high in both 2009 (0.90 [SE = 0.05]) and 2010 (0.96 [SE = 0.03]). Apparent lamb survival to 6 months of age was 0.23 (SE = 0.05) during 2009-2010 and 0.21 (SE = 0.05) during 2010-2011 lambing seasons. Mean body fat for adult females was 12.03% (SE = 0.479) in 2009-2010 and 11.11% (SE= 0.486) in 2010-2011 and was not significantly different between years. Pregnancy rate was 100% in 2009 and 97.5% in 2010.Models containing the previous year’s reproductive effort, spring NDVI and previous year’s reproductive effort and spring precipitation best approximated data on percent body fat in adult females in 2009-2010. In 2010-2011, the two highest-ranking models included the previous year’s reproductive effort and winter NDVI and previous year’s reproductive effort, and winter and spring NDVI. None of the models assessing the influence of maternal body fat, precipitation, or forage conditions were

Physical activity declines across the adult life span despite the well-established links between physical activity and health-related, psychological, cognitive, and social benefits. We contrasted the beliefs young and older adults hold about how aging affects both physical abilities and physical activity and determined whether older adults' beliefs about physical aging relate to their engagement in physical activity. Using visual rating scales, 56 young and 49 community-dwelling older adults indicated the extent to which a typical woman or typical man aged 20-90 possesses six different physical abilities and engages in three different types of physical activity. Stereotypes of physical aging were ability- and activity-specific, and older adults endorsed more positive views than their younger peers. Stereotypical beliefs predicted older adults' engagement in moderate-intensity activity. This study offers intriguing avenues for future research and suggests that better understanding physical aging stereotypes may contribute toward designing interventions that promote lifelong physical activity.

Population-level body condition correlates with productivity in an arctic wader, the dunlin Calidris alpina, during post-breeding migration.

Directory of Open Access Journals (Sweden)

Grzegorz Neubauer

Full Text Available Weather and predation constitute the two main factors affecting the breeding success of those Arctic waders whose productivity is highly variable over the years. We tested whether reproductive success is associated with the post-breeding condition of adults, in which in 'good' years (with warm weather, plentiful food and low predation pressure the condition of breeders and their productivity is high. To verify this hypothesis, we used a 10-year dataset comprising 20,792 dunlins Calidris alpina, trapped during migration at a stopover site on the southern Baltic Sea shore. Males were consistently in a slightly worse condition than females, likely due to male-biased parental investment in brood rearing. Annual productivity indices were positively correlated with the respective condition indices of breeders from the Eurasian Arctic, indicating that in 'good' years, despite great effort spent on reproduction, breeders leave the breeding grounds in better condition. The pattern did not hold for 1992: productivity was low, but the average condition of adults during migration was the highest noted over the decade. We suggest that the delayed effect of the Mount Pinatubo eruption in the Philippines in 1991, could be responsible for the unexpected high condition of Arctic breeders in 1992. High population-level average condition, coupled with the low productivity could stem from severe weather caused by the volcano eruption a year before and strong predation pressure, which in turn lead to a reduced investment in reproduction. The importance of large-scale episodic phenomena, like this volcano eruption, may blur the statistical associations of wildlife with local environmental drivers.

The effects of age on the ability to resolve perceptual ambiguity are unknown, though it depends on fronto-parietal attentional networks known to change with age. We presented the bistable Necker cube to 24 middle-aged and older adults (OA; 56–78 years) and 20 younger adults (YA; 18–24 years) under passive-viewing and volitional control conditions: Hold one cube percept and Switch between cube percepts. During passive viewing, OA had longer dominance durations (time spent on each percept) than YA. In the Hold condition, OA were less able than YA to increase dominance durations. In the Switch condition, OA and YA did not differ in performance. Dominance durations in either condition correlated with performance on tests of executive function mediated by the frontal lobes. Eye movements (fixation deviations) did not differ between groups. These results suggest that OA’s reduced ability to hold a percept may arise from reduced selective attention. The lack of correlation of performance between Hold and executive-function measures suggests at least a partial segregation of underlying mechanisms. PMID:27116194

Health information technology (HIT) is utilized by people with different chronic conditions such as diabetes and hypertension. However, there has been no comparison of HIT use between persons without a chronic condition, with one chronic condition, and multiple (≥2) chronic conditions (MCCs). The aim of the study was to assess the difference in HIT use between persons without a chronic condition, with one chronic condition, and with MCCs, to describe the characteristics of HIT use among those with chronic conditions and to identify the predictors of HIT use of the persons with one chronic condition and MCCs. A secondary data analysis was conducted in spring 2017 using the National Health Interview Survey (NHIS) 2012 Family Core and Sample Adult Core datasets that yielded 34,525 respondents aged 18 years and older. Measures included overall HIT use (ie, any use of the following five HIT on the Internet: seeking health information, ordering prescription, making appointment, emailing health provider, and using health chat groups), as well as sociodemographic and health-related characteristics. Sociodemographic and health characteristics were compared between HIT users and nonusers among those who reported having at least one chronic condition using chi-square tests. Independent predictors of HIT use were identified using multiple logistic regression analyses for those with one chronic condition, with MCCs, and without a chronic condition. Analyses were weighted and performed at significance level of .005. In 2012, adults with one health chronic condition (raw count 4147/8551, weighted percentage 48.54%) was significantly higher than among those with MCCs (3816/9637, 39.55%) and those with none of chronic condition (7254/16,337, 44.40%, PHIT use. Chi-square tests revealed that among adults with chronic conditions, those who used HIT were significantly different from their counterpart peers who did not use HIT in terms of sociodemographic and health characteristics

Sorption of neptunium was studied under aerobic, anoxic and reducing groundwater conditions using solutions with initial Np concentrations of 10 -14 to 10 -8 mol/l. Under aerobic conditions the sorption was the same for all concentrations. Under anoxic conditions the same proportion of neptunium (70-80%) was removed from the water. The neptunium sorbed on rock surfaces was of mixed oxidation states. Only Np(V) was found in waters. Under reducing groundwater conditions, nearly all the neptunium was removed from water. The sorbed neptunium was at first almost completely in the form of Np(IV). The submicrogram amounts of neptunium were partly oxidized with time, but Np(V) did not dissolve in reducing water. The holding oxidant character of the tonalite to Np(V) and, the holding reductant character of rocks to small amounts of Np(IV), was demonstrated under anaerobic and reducing groundwater conditions, respectively.

2013-11-01

This study was conducted to evaluate the effect of dietary vitamin E (VE) on broiler meat quality, especially focused on PSE (pale color, soft and exudative), under chronic heat stress (HS) conditions. Twenty-eight-day-old female Ross broilers were kept in independent cages with a controlled temperature of 24°C (normal temperature: NT) or 30°C (high temperature: HT). The NT chickens were fed basal feed. The HT chickens were fed basal feed (HT) or VE (200 mg/kg) added feed (HT + E). Broilers were weighed and slaughtered at 38 days old. The breast muscle was removed immediately and then the samples were used for determination of meat color, pH, water holding capacity (WHC) and shear force value (SFV). Body weight gain and feed intake were significantly decreased in the HT and HT + E groups compared to the NT group. VE supplementation did not affect the growth performance. Chronic HS at 30°C for 10 days may cause deterioration of meat quality such as PSE. The effects of chronic HS on meat quality were most significant in the toughness of broiler breast meat. Supplementation of VE in broiler feed would be effective to prevent the extent of PSE on broiler meat by chronic HS. © 2013 Japanese Society of Animal Science.

Childhood conditions and education as determinants of adult height and obesity among Greenland Inuit

This study examined ways that young adults with mental illnesses (1) currently use social networking; and (2) how they would like to use a social networking site tailored for them. The authors examined differences between those with mental health conditions and those without. An online survey was administered by the National Alliance on Mental Illness (NAMI) to 274 participants; of those, 207 reported being between 18 and 24 years old. The survey included questions about current social networking use, the key resources respondents believed young adults living with mental illness need, and the essential components that should be included in a social networking site specifically tailored to young adults living with mental illness. Pearson Chi-square analyses examined the differences between those who reported having a mental illness and those who did not. Results indicate that almost all (94%) participants with mental illnesses currently use social networking sites. Individuals living with a mental illness are more likely than those not living with a mental illness to report engaging in various social networking activities that promote connectivity and making online friends. Individuals living with mental illnesses are also more likely to report wanting resources on independent living skills and overcoming social isolation available on a social networking site. Young adults living with mental illnesses are currently using social networking sites and express high interest in a social networking site specifically tailored to their population with specific tools designed to decrease social isolation and help them live more independently. These results indicate that practitioners should themselves be aware of the different social networking sites frequented by their young adult clients, ask clients about their use of social networking, and encourage safe and responsible online behaviors.

Aim: To determine whether a single 20 s breath-hold positron-emission tomography (PET) acquisition obtained during combined PET/computed tomography (CT)-guided percutaneous liver biopsy or ablation procedures has the potential to target 2-[ 18 F]-fluoro-2-deoxy-D-glucose (FDG)-avid liver masses as accurately as up to 180 s breath-hold PET acquisitions. Materials and methods: This retrospective study included 10 adult patients with 13 liver masses who underwent FDG PET/CT-guided percutaneous biopsies (n = 5) or ablations (n = 5). PET was acquired as nine sequential 20 s, monitored, same-level breath-hold frames and CT was acquired in one monitored breath-hold. Twenty, 40, 60, and 180 s PET datasets were reconstructed. Two blinded readers marked tumour centres on randomized PET and CT datasets. Three-dimensional spatial localization differences between PET datasets and either 180 s PET or CT were analysed using multiple regression analyses. Statistical tests were two-sided and p < 0.05 was considered significant. Results: Targeting differences between 20 s PET and 180 s PET ranged from 0.7–20.3 mm (mean 5.3 ± 4.4 mm; median 4.3) and were not statistically different from 40 or 60 s PET (p = 0.74 and 0.91, respectively). Targeting differences between 20 s PET and CT ranged from 1.4–36 mm (mean 9.6 ± 7.1 mm; median 8.2 mm) and were not statistically different from 40, 60, or 180 s PET (p = 0.84, 0.77, and 0.35, respectively). Conclusion: Single 20 s breath-hold PET acquisitions from PET/CT-guided percutaneous liver procedures have the potential to target FDG-avid liver masses with equivalent accuracy to 180 s summed, breath-hold PET acquisitions and may facilitate strategies that improve image registration and shorten procedure times

Determinants of corporate cash holdings: Evidence from Portuguese publicly traded firms

Directory of Open Access Journals (Sweden)

Fernandes, Filipa

2017-05-01

Full Text Available This paper investigates the determinants of cash holdings of publicly traded Portuguese firms. We find that such firms hold less cash than similar companies operating in countries where both shareholders and creditors’ rights are more tightly protected by the law. In addition, our regression results suggest that leverage, other liquid assets, and firm growth are negatively correlated with our sample firms’ cash holdings whereas long-term debt and financial distress are positively correlated. Our findings cannot be reconciled with just one of the existent theories (trade-off, pecking order and free cashflow theory, and emphasize the importance of a country’s legal, institutional, and economic environment for explaining firms’ cash holdings decisions.

A comparison of liquid-holding recovery and photoreactivation in halophilic and non-halophilic bacteria

Fitt, P.S.; Sharma, N.; Castellanos, G.

1983-01-01

The ability of the extreme halophile Halobacterium cutirubrum to recover from the effects of ultraviolet radiation during liquid holding in the dark in non-nutrient medium has been compared with that of (i) a moderately halophilic bacterium (NRC 41227) and (ii) Escherichia coli B. The photoreactivabilities of all three bacteria have also been studied. The extreme halophile was incapable of liquid-holding recovery in these conditions, in marked contrast to both E. coli B and the moderate halophile, and also failed to recover when held in nutrient medium in the dark. These results strongly support the hypothesis that H. cutirubrum lacks DNA excision repair. It was also found that ultraviolet-irradiated H. cutirubrum could be almost completely photoreactivated from any level of survival in the range 10 - 4 -80%, provided exposure to visible light was not delayed, whereas the moderate halophile resembled E. coli B and had a comparatively limited capacity for photoreactivation.

FUNCTIONING OF AGRICULTURAL HOLDINGS IN UKRAINE: STRONG AND WEAK SIDES

Directory of Open Access Journals (Sweden)

Postgraduate, assistant Sergii Ivanovich TODORIUK

2014-06-01

Full Text Available One of the organizational forms of the agricultural management which is gaining popularity in the world is agricultural holdings. The essence of agricultural holdings is considered in the article. Also the peculiarities of their functioning in Ukraine and determination of the strengths and weaknesses of their activities is defined, as well as perspectives of their further functioning. Agrarian holding, as a relatively new organizational legal form of managing in Ukraine has its advantages and disadvantages. As the experience shows the advantages of agrarian holdings over the subjects of management are revealed mainly in the economic sphere. While their disadvantages over the subjects of management are revealed in social and ecological spheres. This is a negative moment considering the implementation in Ukraine of the concept of the sustainable development, which means the combination of these main components (economic component, environmental component, social component.

Control of cooperative manipulators in holding deformable objects

Science.gov (United States)

Alkathiri, A. A.; Azlan, N. Z.

2017-11-01

This paper presents the implementation of a control system to control cooperative manipulators to hold deformable objects. The aim is to hold the deformable object without having information on the shape and stiffness of the deformable object beforehand. The prototype of a pair of manipulators has been designed and built to test the controller. A force sensor and a rotary encoder are used to give feedback to the controller, which controls the DC motor actuators accordingly. A position proportional-integral-derivative (PID) controller technique has been applied for one of the manipulators and a PID force control technique is applied to the other. Simulations and experimental tests have been conducted on models and the controller has been implemented on the real plant. Both simulation and test results prove that the implemented control technique has successfully provided the desired position and force to hold the deformable object with maximum experimental errors of 0.34mm and 50mN respectively.

DOES UNCOVERED INTEREST RATE PARITY HOLD IN TURKEY?

Directory of Open Access Journals (Sweden)

Ozcan Karahan

2012-01-01

Full Text Available Most of the earlier empirical studies focusing on developed countries failed to give evidence in favor of the Uncovered Interest Rate Parity (UIP. After intensive financial liberalization processes and mostly preferred free exchange rate regimes, a new area of research starts to involve the investigation whether UIP holds for developing economies differently. Accordingly, we tested the UIP for Turkey’s monthly interest rate and exchange rate data between 2002 and 2011. We run conventional regressions in the form of Ordinary Least Squares (OLS and used a simple Generalized Autoregressive Conditional Heteroskedasticity (GARCH analysis. The empirical results of both methods do not support the validity of UIP for Turkey. Thus, together with most of the earlier empirical studies focusing on developed countries and detecting the invalidity of UIP, we can argue that the experience of Turkey and developed economies are not different.

2014-01-01

Full Text Available This study examines the association between state and county unemployment rates and individuals’ body weight status during the latest recession in the U.S. We used the U.S. Behavioral Risk Factor Surveillance System (BRFSS data in 2007, 2009 and 2011, which were collected from 722,692 American adults aged 18 or older. Overweight and obesity were defined as body mass index (BMI ≥25, and ≥30, respectively. Multivariate linear and logistic regressions were applied to assess the association between BMI, risks of overweight and obesity, and state and county unemployment rates. State unemployment rates were negatively associated with individual BMI across years, while county unemployment rates were significantly positively associated with BMI and obesity rates in all years (p < 0.05. However, the scale of the positive relationship was reduced in 2009 and 2011. Stratified analyses were conducted among adults with employment and without employment. The unemployed group’s body weight status was not related to state- and county-level economic conditions in most times. In the pooled analyses with all three years’ data, the relationship between unemployment rates and body weight status were consistently reduced after the recession of 2008–2009. Our results indicated that macroeconomic conditions at different levels can have different associations with individuals’ obesity risk across time.

Howard, Samuel Clarence

1988-01-01

Sewage-holding tanks aboard recreational boats store human wastes, thereby preventing the direct discharge of wastewater to the aquatic environment. Water-conserving toilets and limited holding tank volumes produce a highly concentrated waste that must be periodically dumped to a wastewater treatment system. Prior to disposal, many boat operators add commercial preparations to control odors produced in their chemical toilets and holding tanks. The objective of this study was to determine t...

Does social distance modulate adults' egocentric biases when reasoning about false beliefs?

Science.gov (United States)

Farrar, Benjamin G; Ostojić, Ljerka

2018-01-01

When given privileged information of an object's true location, adults often overestimate the likelihood that a protagonist holding a false belief will search in the correct location for that object. This type of egocentric bias is often labelled the 'curse of knowledge'. Interestingly, the magnitude of this bias may be modulated by the social distance between the perspective taker and target. However, this social distance effect has yet to be fully demonstrated when adults reason about false beliefs. Using a continuous false belief task, we investigated i) whether adults were biased by their own knowledge when reasoning about another's false belief, ii) whether the magnitude of this egocentric bias was modulated by social distance, and iii) whether this social distance effect extended to a heterospecific out-group, namely a dog. To test these hypotheses we conducted three experiments. In Experiment 1 (N = 283), we used an established continuous false belief task, in Experiment 2 (N = 281) we modified this task, and Experiment 3 (N = 744) was a direct replication of Experiment 2. Across these experiments, the curse of knowledge effect was reliably replicated when adults mentalised about an in-group protagonist, and replicated in two of the three studies (Experiments 1 and 3) when adults mentalised about out-group protagonists. In an internal-meta analysis, the curse of knowledge effect was present across all conditions, and there was no effect of social distance. Hence, overall these data are not consistent with the hypothesis that social distance modulates adults' egocentric biases when reasoning about false beliefs. The finding that egocentric biases of a similar magnitude were observed when adults mentalised about an in-group protagonist and a dog suggests that interpersonal dissimilarity is not in itself sufficient to reduce egocentric bias when reasoning about false beliefs.

Estimates of fire environments in ship holds containing radioactive material packages

International Nuclear Information System (INIS)

Koski, J.A.; Cole, J.K.; Hohnstreiter, G.F.; Wix, S.D.

1995-01-01

Fire environments that occur on cargo ships differ significantly from the fire environments found in land transport. Cargo ships typically carry a large amount of flammable fuel for propulsion and shipboard power, and may transport large quantities of flammable cargo. As a result, sea mode transport accident records contain instances of long lasting and intense fires. Since Irradiated Nuclear Fuel (INF) casks are not carried on tankers with large flammable cargoes, most of these dramatic, long burning fires are not relevant threats, and transport studies must concentrate on those fires that are most likely to occur. By regulation, INF casks must be separated from flammable cargoes by a fire-resistant, liquid-tight partition. This makes a fire in an adjacent ship hold the most likely fire threat. The large size of a cargo ship relative to any spent nuclear fuel casks on board, however, may permit a severe, long lasting fire to occur with little or no thermal impact on the casks. Although some flammable materials such as shipping boxes or container floors may exist in the same hold with the cask, the amount of fuel available may not provide a significant threat to the massive transport casks used for radioactive materials. This shipboard fire situation differs significantly from the regulatory conditions specified in 10 CFR 71 for a fully engulfing pool fire. To learn more about the differences, a series of simple thermal analyses has been completed to estimate cask behavior in likely marine and land thermal accident situations. While the calculations are based on several conservative assumptions, and are only preliminary, they illustrate that casks are likely to heat much more slowly in shipboard hold fires than in an open pool fire. The calculations also reinforce the basic regulatory concept that for radioactive materials, the shipping cask, not the ship, is the primary protection barrier to consider

Madsen, Heather B; Zbukvic, Isabel C; Luikinga, Sophia J; Lawrence, Andrew J; Kim, Jee Hyun

2017-09-01

Relapse to drug use is often precipitated by exposure to drug associated cues that evoke craving. Cue-induced drug craving has been observed in both animals and humans to increase over the first few weeks of abstinence and remain high over extended periods, a phenomenon known as 'incubation of craving'. As adolescence represents a period of vulnerability to developing drug addiction, potentially due to persistent reactivity to drug associated cues, we first compared incubation of cocaine craving in adolescent and adult rats. Adolescent (P35) and adult (P70) rats were trained to lever press to obtain intravenous cocaine, with each drug delivery accompanied by a light cue that served as the conditioned stimulus (CS). Following acquisition of stable responding, rats were tested for cue-induced cocaine-seeking after either 1 or 30days of abstinence. Additional groups of rats were also tested after 30days of abstinence, however these rats were subjected to a cue extinction session 1week into the abstinence period. Rats were injected with aripiprazole, a dopamine 2 receptor (D2R)-like partial agonist, or vehicle, 30min prior to cue extinction. We found that adolescent and adult rats acquired and maintained a similar level of cocaine self-administration, and rats of both ages exhibited a higher level of cue-induced cocaine-seeking if they were tested after 30days of abstinence compared to 1day. Incubation of cocaine craving was significantly reduced to 1day levels in both adults and adolescents that received cue extinction training. Administration of aripiprazole prior to cue extinction did not further reduce cue-induced drug-seeking. These results indicate that cue extinction training during abstinence may effectively reduce cue-induced relapse at a time when cue-induced drug craving is usually high.

Patient-provider relationship as mediator between adult attachment and self-management in primary care patients with multiple chronic conditions.

Science.gov (United States)

Brenk-Franz, Katja; Strauß, Bernhard; Tiesler, Fabian; Fleischhauer, Christian; Schneider, Nico; Gensichen, Jochen

2017-06-01

The conceptual model of attachment theory has been applied to understand the predispositions of patients in medical care and the patient-provider relationship. In patients with chronic conditions insecure attachment was connected to poorer self-management. The patient-provider relationship is associated with a range of health related outcomes and self-management skills. We determined whether the quality of the patient-provider relationship mediates the link between adult attachment and self-management among primary care patients with multiple chronic diseases. 209 patients with a minimum of three chronic diseases (including type II diabetes, hypertension and at least one other chronic condition) between the ages of 50 and 85 from eight general practices were included in the APRICARE cohort study. Adult attachment was measured via self-report (ECR-RD), self-management skills by the FERUS and the patient-provider relationship by the PRA-D. The health status and chronicity were assessed by the GP. Multiple mediation analyses were used to examine whether aspects of the patient-provider relationship (communication, information, affectivity) are a mediators of associations between adult attachment and self-management. The analysis revealed that the quality of the patient-provider relationship mediated the effect of attachment on self-management in patients with multiple chronic conditions. Particularly the quality of communication and information over the course of treatment has a significant mediating influence. A personalized, attachment-related approach that promotes active patient-provider communication and gives information about the treatment to the patient may improve self-management skills in patients.

While marijuana has been legal for medical purposes in California since 1996, little is known about the health histories of young adult medical marijuana patients who are a significant proportion of medical marijuana patients. We examined whether young adult medical marijuana patients reported health conditions and motivations for use that were consistent with medical use of marijuana in California. Young adults (N = 366) aged 18 to 26 years were sampled in Los Angeles in 2014-2015 and segmented into medical marijuana 'patients' (n = 210), marijuana users with a current recommendation, and non-patient users or 'non-patients' (n = 156), marijuana users who never had a medical marijuana recommendation. Differences between patients and non-patients regarding self-reported health histories and past/current motivations for marijuana use were expressed as unadjusted risk ratios. Compared with non-patients, patients were significantly more likely to report a range of lifetime health problems, such as psychological, physical pain and gastrointestinal. In the past 90 days, patients were significantly more likely to report motivations for marijuana use than non-patients concerning sleep, anxiety, physical pain and focusing. Psychological and pain problems were the most common health conditions reported to receive a medical marijuana recommendation. Patients were significantly less likely than non-patients to report any privacy concerns about obtaining a medical marijuana recommendation. Patients were significantly more likely to report a range of health conditions and motivations associated with medical use than non-patients. A great majority of patients reported obtaining a medical marijuana recommendation for health problems in accordance with the California law.

Passing It On: Parent-to-Adult Child Financial Transfers for School and Socioeconomic Attainment

Directory of Open Access Journals (Sweden)

Emily Rauscher

2016-10-01

Full Text Available As wealth inequality increases, the importance of parental financial transfers for socioeconomic attainment may also rise. Using data from the 2013 Panel Study of Income Dynamics Rosters and Transfers Module, this study investigates two questions: how parental financial transfers for education have changed over time, and what the relationship is between these transfers and adult socioeconomic outcomes. Results suggest that transfers for education have increased, have become more commonplace, and have become more dependent on parental wealth over time. Holding constant several individual and parental measures, the relationship between parental transfers for school and adult socioeconomic attainment is positive. This relationship holds when using three-stage least squares models to account for potential endogeneity of financial transfers for school. Overall, results support arguments that parental financial transfers for education facilitate the intergenerational transmission of socioeconomic standing.

Preliminary studies performed at a research slaughterhouse revealed a high correlation between WHC and both IR (r=0.89) and Raman spectra using Partial Least Squares Regressions (PLSR). The good results were confirmed under industrial conditions using...... FT-IR at-line spectroscopy. However, the latter experiment yielded a somewhat lower correlation (r=0.79). This result is, however, promising for the purpose of finding a method for classification of carcasses with regard to WHC at the slaughter line. The IR region 1800–900 cm−1 contains the best...

Water addition, evaporation and water holding capacity of poultry litter.

Dunlop, Mark W; Blackall, Patrick J; Stuetz, Richard M

2015-12-15

Litter moisture content has been related to ammonia, dust and odour emissions as well as bird health and welfare. Improved understanding of the water holding properties of poultry litter as well as water additions to litter and evaporation from litter will contribute to improved litter moisture management during the meat chicken grow-out. The purpose of this paper is to demonstrate how management and environmental conditions over the course of a grow-out affect the volume of water A) applied to litter, B) able to be stored in litter, and C) evaporated from litter on a daily basis. The same unit of measurement has been used to enable direct comparison-litres of water per square metre of poultry shed floor area, L/m(2), assuming a litter depth of 5cm. An equation was developed to estimate the amount of water added to litter from bird excretion and drinking spillage, which are sources of regular water application to the litter. Using this equation showed that water applied to litter from these sources changes over the course of a grow-out, and can be as much as 3.2L/m(2)/day. Over a 56day grow-out, the total quantity of water added to the litter was estimated to be 104L/m(2). Litter porosity, water holding capacity and water evaporation rates from litter were measured experimentally. Litter porosity decreased and water holding capacity increased over the course of a grow-out due to manure addition. Water evaporation rates at 25°C and 50% relative humidity ranged from 0.5 to 10L/m(2)/day. Evaporation rates increased with litter moisture content and air speed. Maintaining dry litter at the peak of a grow-out is likely to be challenging because evaporation rates from dry litter may be insufficient to remove the quantity of water added to the litter on a daily basis.

Crack growth under combined creep and fatigue conditions in alloy 800

International Nuclear Information System (INIS)

Pfaffelhuber, M.; Roedig, M.; Schubert, F.; Nickel, H.

1989-08-01

To investigate the crack growth behaviour under combined creep-fatigue loading, CT 25 mm-specimens of X10NiCrAlTi 32 20 (Alloy 800) have been tested in experiments with cyclic loadings and hold times, with static loadings and short stress rekief interrupts, with ramp type loadings and with sequences of separate fatigue and creep crack growth periods. The test temperature of 700deg C was selected because only in this temperature range this alloy provides similar amounts of crack growth under creep and fatigue conditions due to equivalent stress levels. For the estimation of crack growth under combined loading conditions a linear accumulation of increase in crack length was proved using the crack growth laws of pure creep and fatigue crack growth. Hold time and ramp loadings lead to a higher crack growth rate compared with pure creep or pure fatigue crack growth tests. In hold time experiments the crack growth rate is higher than ramp tests of the same period time. The results of hold time tests can be fairly enough predicted by linear damage accumulation rules.

Impact of collection container material and holding times on sample integrity for mercury and methylmercury in water

Energy Technology Data Exchange (ETDEWEB)

Riscassi, Ami L [ORNL; Miller, Carrie L [ORNL; Brooks, Scott C [ORNL

2014-01-01

Mercury (Hg) and methylmercury (MeHg) concentrations in streamwater can vary on short timescales (hourly or less) during storm flow and on a diel cycle; the frequency and timing of sampling required to accurately characterize these dynamics may be difficult to accomplish manually. Automated sampling can assist in sample collection; however use has been limited for Hg and MeHg analysis due to stability concerns of trace concentrations during extended storage times. We examined the viability of using automated samplers with disposable low-density polyethylene (LDPE) sample bags to collect industrially contaminated streamwater for unfiltered and filtered Hg and MeHg analysis. Specifically we investigated the effect of holding times ranging from hours to days on streamwater collected during baseflow and storm flow. Unfiltered and filtered Hg and MeHg concentrations decreased with increases in time prior to sample processing; holding times of 24 hours or less resulted in concentration changes (mean 11 7% different) similar to variability in duplicates collected manually during analogous field conditions (mean 7 10% different). Comparisons of samples collected with manual and automated techniques throughout a year for a wide range of stream conditions were also found to be similar to differences observed between duplicate grab samples. These results demonstrate automated sampling into LDPE bags with holding times of 24 hours or less can be effectively used to collect streamwater for Hg and MeHg analysis, and encourage the testing of these materials and methods for implementation in other aqueous systems where high-frequency sampling is warranted.

Survival and weight change among adult individuals of Periplaneta americana (Linnaeus, 1758 (Blattaria, Blattidae subject to various stress conditions

Directory of Open Access Journals (Sweden)

Jucelio Peter Duarte

2015-05-01

Full Text Available Periplaneta americana is a species of great importance to public health, since it can act as a vector of many pathogens and it reaches large populations in urban environments. This is probably due to its ability to resist starvation and desiccation. This study aimed to evaluate the effects of absence of water and food on survival and weight change among adult P. americana individuals and check whether the initial weight of individuals influences on their survival. Four groups having twenty P. americana couples were formed and subject to: I no water or food; II no food; III no water; and IV control group. Insects were isolated according to the groups, which were weighed at the beginning and end of the stress conditions. They remained under these conditions until all individuals in each test group were dead. Stress conditions caused reduction in survival time when compared to the control group. Adults with higher body mass survived longer when deprived only of food, while among those lacking water, weight had no influence on survival. Total weight loss was greater among individuals deprived of water than those deprived only of food.

Insect behaviors are often influenced by light conditions including photoperiod, light intensity, and wavelength. Understanding pest insect responses to changing light conditions may help with developing alternative strategies for pest control. Little is known about the behavioral responses of leafhoppers (Hemiptera: Cicadellidae) to light conditions. The behavior of the tea green leafhopper, Empoasca onukii Matsuda, was examined when exposed to different light photoperiods or wavelengths. Observations included the frequency of locomotion and cleaning activities, and the duration of time spent searching. The results suggested that under normal photoperiod both female and male adults were generally more active in darkness (i.e., at night) than in light. In continuous darkness (DD), the locomotion and cleaning events in Period 1 (7:00-19:00) were significantly increased, when compared to the leafhoppers under normal photoperiod (LD). Leafhoppers, especially females, changed their behavioral patterns to a two day cycle under DD. Under continuous illumination (continuous quartz lamp light, yellow light at night, and green light at night), the activities of locomotion, cleaning, and searching were significantly suppressed during the night (19:00-7:00) and locomotion activities of both females and males were significantly increased during the day (7:00-19:00), suggesting a shift in circadian rhythm. Our work suggests that changes in light conditions, including photoperiod and wavelength, can influence behavioral activities of leafhoppers, potentially affecting other life history traits such as reproduction and development, and may serve as a method for leafhopper behavioral control.

Ireland, Jane L; Power, Christina L; Bramhall, Sarah; Flowers, Catherine

2009-01-01

Few studies have attempted to explore attitudes towards bullying among prisoners, despite acknowledgement that attitudes may play an important role. To evaluate the structure of a new attitudinal scale, the Prison Bullying Scale (PBS), with adult men and women in prison and with young male prisoners. That attitudes would be represented as a multidimensional construct and that the PBS structure would be replicated across confirmatory samples. The PBS was developed and confirmed across four independent studies using item parceling and confirmatory factor analysis: Study I comprised 412 adult male prisoners; Study II, 306 adult male prisoners; Study III, 171 male young offenders; and Study IV, 148 adult women prisoners. Attitudes were represented as a multidimensional construct comprising seven core factors. The exploratory analysis was confirmed in adult male samples, with some confirmation among young offenders and adult women. The fit for young offenders was adequate and improved by factor covariance. The fit for women was the poorest overall. The study notes the importance of developing ecologically valid measures and statistically testing these measures prior to their clinical or research use. The development of the PBS holds value both as an assessment and as a research measure and remains the only ecologically validated measure in existence to assess prisoner attitudes towards bullying.

Health risks and changes in self-efficacy following community health screening of adults with serious mental illnesses.

Directory of Open Access Journals (Sweden)

Judith A Cook

Full Text Available Physical health screenings were conducted by researchers and peer wellness specialists for adults attending publicly-funded community mental health programs. A total of 457 adults with serious mental illnesses attended health fairs in 4 U.S. states and were screened for 8 common medical co-morbidities and health risk factors. Also assessed were self-reported health competencies, medical conditions, and health service utilization. Compared to non-institutionalized U.S. adults, markedly higher proportions screened positive for obesity (60%, hypertension (32%, diabetes (14%, smoking (44%, nicotine dependence (62%, alcohol abuse (17%, drug abuse (11%, and coronary heart disease (10%. A lower proportion screened positive for hyperlipidemia (7%. Multivariable random regression analysis found significant pre- to post-screening increases in participants' self-rated abilities for health practices, competence for health maintenance, and health locus of control. Screening identified 82 instances of undiagnosed diabetes, hypertension or hyperlipidemia, and 76 instances where these disorders were treated but uncontrolled. These results are discussed in the context of how this global public health approach holds promise for furthering the goal of integrating health and mental health care.

The results described the distribution of early-onset dementia conditions in 53 adolescents and adults with DS, and 2.6% of the subjects with DS had possible dementia (DSQIID score ≧ 20). Univariate analyses found that older age (p=0.001) and comorbid conditions (p=0.003) were significantly associated with DSQIID scores. Older subjects were more likely to have higher DSQIID scores than were younger age groups after ANOVA and Scheffe's tests. Lastly, a multiple linear regression analysis revealed that age (p<0.01), severe disability level (p<0.05) and comorbid condition (p<0.01) significantly explained 13% of the variation in DSQIID scores after adjusting for the factors of gender, education level and multiple disabilities in adolescents and adults with DS. The study highlights that future research should focus on the occurrence of dementia in people with DS and on identifying its influencing factors based on sound measurements, to initiate appropriate healthy aging policies for this group of people.

Stathokostas, L; Dogra, S; Paterson, D H

2015-10-01

The aim of this paper was to examine the independent influence of cardiorespiratory fitness and sedentary behavior on chronic disease incidence and body composition in older adults. A sample of 292 community dwelling men and women (mean 69.3±8.1 years) underwent maximal treadmill testing and completed questionnaires relating to their leisure-time physical activity, sedentary time, and health. The average V O2 of the sample was approximately 21 ml.kg(-1).min(-1) with the average sedentary time being over 3 hours per day. Cardiorespiratory fitness was found to be a stronger predictor of number of chronic conditions and BMI than total physical activity and sedentary. Those with a higher cardiorespiratory fitness had fewer chronic conditions and a lower BMI. No such associations were seen for either total physical activity levels or sedentary time. Cardiorespiratory fitness is a stronger predictor of health among older adults and further highlights the importance of promoting public health guidelines for cardiorespiratory fitness.

Full Text Available Negative social experiences during adolescence increase the risk of psychiatric disorders in adulthood. Using resident-intruder stress, the present study aimed to investigate the effects of adolescent social defeat on emotional and cognitive symptoms associated with psychiatric disorders during adulthood and the effects of the developmental stage and social condition on this process. In experiment 1, animals were exposed to social defeat or manipulation for 10 days during early adolescence (EA, PND 28-37, late adolescence (LA, PND 38-47, and adulthood (ADULT, PND 70-79 and then singly housed until the behavioral tests. Behaviors, including social avoidance of the defeat context and cortically mediated cognitive flexibility in an attentional set-shifting task (AST, were assessed during the week following stress or after 6 weeks during adulthood. We determined that social defeat induced significant and continuous social avoidance across age groups at both time points. The mice that experienced social defeat during adulthood exhibited short-term impairments in reversal learning on the AST that dissipated after 6 weeks. In contrast, social defeat during EA but not LA induced a delayed deficit in extra-dimensional set-shifting in adulthood but not during adolescence. In experiment 2, we further examined the effects of social condition (isolation or social housing after stress on the alterations induced by social defeat during EA in adult mice. The adult mice that had experienced stress during EA exhibited social avoidance similar to the avoidance identified in experiment 1 regardless of the isolation or social housing after the stress. However, social housing after the stress ameliorated the cognitive flexibility deficits induced by early adolescent social defeat in the adult mice, and the social condition had no effect on cognitive function. These findings suggest that the effects of social defeat on emotion and cognitive function are differentially

Purpose: To assess the clinical efficacy of auto beam hold during prostate RapidArc delivery, triggered by fiducial localization on kV imaging with a Varian True Beam. Methods: Prostate patients with four gold fiducials were candidates in this study. Daily setup was accomplished by aligning to fiducials using orthogonal kV imaging. During RapidArc delivery, a kV image was automatically acquired with a momentary beam hold every 60 degrees of gantry rotation. The position of each fiducial was identified by a search algorithm and compared to a predetermined 1.4 cm diameter target area. Treatment continued if all the fiducials were within the target area. If any fiducial was outside the target area the beam hold was not released, and the operators determined if the patient needed re-alignment using the daily setup method. Results: Four patients were initially selected. For three patients, the auto beam hold performed seamlessly. In one instance, the system correctly identified misaligned fiducials, stopped treatment, and the patient was re-positioned. The fourth patient had a prosthetic hip which sometimes blocked the fiducials and caused the fiducial search algorithm to fail. The auto beam hold was disabled for this patient and the therapists manually monitored the fiducial positions during treatment. Average delivery time for a 2-arc fraction was increased by 59 seconds. Phantom studies indicated the dose discrepancy related to multiple beam holds is <0.1%. For a plan with 43 fractions, the additional imaging increased dose by an estimated 68 cGy. Conclusion: Automated intrafraction kV imaging can effectively perform auto beam holds due to patient movement, with the exception of prosthetic hip patients. The additional imaging dose and delivery time are clinically acceptable. It may be a cost-effective alternative to Calypso in RapidArc prostate patient delivery. Further study is warranted to explore its feasibility under various clinical conditions.

How Important Is a Reproducible Breath Hold for Deep Inspiration Breath Hold Breast Radiation Therapy?

International Nuclear Information System (INIS)

Wiant, David; Wentworth, Stacy; Liu, Han; Sintay, Benjamin

2015-01-01

Purpose: Deep inspiration breath hold (DIBH) for left-sided breast cancer has been shown to reduce heart dose. Surface imaging helps to ensure accurate breast positioning, but it does not guarantee a reproducible breath hold (BH) at DIBH treatments. We examine the effects of variable BH positions for DIBH treatments. Methods and Materials: Twenty-five patients who underwent free breathing (FB) and DIBH scans were reviewed. Four plans were created for each patient: FB, DIBH, FB-DIBH (the DIBH plans were copied to the FB images and recalculated, and image registration was based on breast tissue), and P-DIBH (a partial BH with the heart shifted midway between the FB and DIBH positions). The FB-DIBH plans give a “worst-case” scenario for surface imaging DIBH, where the breast is aligned by surface imaging but the patient is not holding their breath. Kolmogorov-Smirnov tests were used to compare the dose metrics. Results: The DIBH plans gave lower heart dose and comparable breast coverage versus FB in all cases. The FB-DIBH plans showed no significant difference versus FB plans for breast coverage, mean heart dose, or maximum heart dose (P≥.10). The mean heart dose differed between FB-DIBH and FB by <2 Gy for all cases, and the maximum heart dose differed by <2 Gy for 21 cases. The P-DIBH plans showed significantly lower mean heart dose than FB (P<.01). The mean heart doses for the P-DIBH plans were < FB for 22 cases, the maximum dose was < FB for 18 cases. Conclusions: A DIBH plan delivered to a FB patient setup with surface imaging will yield dosimetry similar to that of a plan created and delivered FB. A DIBH plan delivered with even a partial BH can give reduced heart dose compared with FB techniques.

Nakamura, Hisashi; Tanaka, Nobuo; Takahashi, Katsuro.

1985-01-01

Purpose: To improve the function of cooling to hold molten core materials in a molten core material holding device. Constitution: Plenum structures are formed into a pan-like configuration, in which liners made of metal having high melting point and relatively high heat conductivity such as tantalum, tungsten, rhenium or alloys thereof are integrally appended to hold and directly cool the molten reactor core materials. Further, a plurality of heat pipes, passing through the plenum structures, facing the cooling portion thereof to the coolants at the outer side and immersing the heating portion into the molten core materials fallen to deposit in the inner liners are disposed radially. Furthermore, heat pipes embodded in the plenum structure are disposed in the same manner below the liners. Thus, the plenum structures and the molten reactor core materials can be cooled at a high efficiency. (Seki, T.)

Task difficulty has no effect on haptic anchoring during tandem walking in young and older adults.

Costa, Andréia Abud da Silva; Santos, Luciana Oliveira Dos; Mauerberg-deCastro, Eliane; Moraes, Renato

2018-02-14

This study assessed the contribution of the "anchor system's" haptic information to balance control during walking at two levels of difficulty. Seventeen young adults and seventeen older adults performed 20 randomized trials of tandem walking in a straight line, on level ground and on a slightly-raised balance beam, both with and without the use of the anchors. The anchor consists of two flexible cables, whose ends participants hold in each hand, to which weights (125 g) are attached at the opposing ends, and which rest on the ground. As the participants walk, they pull on the cables, dragging the anchors. Spatiotemporal gait variables (step speed and single- and double-support duration) were processed using retro-reflective markers on anatomical sites. An accelerometer positioned in the cervical region registered trunk acceleration. Walking on the balance beam increased single- and double-support duration and reduced step speed in older adults, which suggests that this condition was more difficult than walking on the level ground. The anchors reduced trunk acceleration in the frontal plane, but the level of difficulty of the walking task showed no effect. Thus, varying the difficulty of the task had no influence on the way in which participants used the anchor system while tandem walking. The older adults exhibited more difficulty in walking on the balance beam as compared to the younger adults; however, the effect of the anchor system was similar in both groups.

Factors Affecting Corporate Cash Holding of Non-Financial Firms in Pakistan

Directory of Open Access Journals (Sweden)

Atif Kafayat

2014-06-01

Full Text Available The previous researches explore the question of why firms hold cash. But there are few researches done in developing countries like Pakistan. The need for cash is characterized by its policies of firms regarding capital structure, working capital requirements, cash flow management, dividend payments, and asset management. In this paper, the impact of these factors is normally analyzed under the framework of Tradeoff theory, Pecking Order Theory and Free Cash Flow Theory. This paper focuses on determining the level of corporate cash holdings of non-financial Pakistani firms, and cash holding requirement among different industries. The data is set for period of 2008- 2012 by using the data of 40companies and 6 industries. The findings of the study support the theories. Which show that firm size, net working capital, leverage, Capital Expenditure and Dividend significantly affect the cash holdings of non-financial firms in Pakistan.

Internationalization and Corporate Cash Holdings: Evidence from Brazil and Mexico

Directory of Open Access Journals (Sweden)

Newton Arata

2015-05-01

Full Text Available This research expands on previous studies of cash holdings and their determinants by studying the relationship between the degree of internationalization and the level of corporate cash holdings. We used a sample of nonfinancial, publicly traded companies from Brazil and Mexico for the period from 2006 to 2010. Our results suggest that the degree of internationalization is a determinant of cash, and that cash holding increases quadratically as the degree of company internationalization grows. Such behavior was different from the North American company studies in Chiang and Wang (2011. Similar to previous studies, both Trade-off and Pecking Order predictions are relevant control variables in our model. Finally, companies held less cash on their balance sheets during the precrisis period.

Alperstein, Neil M

2014-01-01

This study examines awareness and knowledge of and attitudes toward direct-to-consumer (DTC) prescription drug advertising among young adults between 18 and 24 years of age. The study finds that young adults are not as aware of prescription drug advertising as older consumers, however, they are aware of specific heavily advertised drugs, especially those for allergy medications, birth control, and sleep aids. Young adults hold mixed to negative views about advertising in general, and they do not view DTC prescription drug advertising as a beneficial source of information, nor do they believe such advertising serves to educate consumers.

Reliable quantification of BOLD fMRI cerebrovascular reactivity despite poor breath-hold performance.

Bright, Molly G; Murphy, Kevin

2013-12-01

Cerebrovascular reactivity (CVR) can be mapped using BOLD fMRI to provide a clinical insight into vascular health that can be used to diagnose cerebrovascular disease. Breath-holds are a readily accessible method for producing the required arterial CO2 increases but their implementation into clinical studies is limited by concerns that patients will demonstrate highly variable performance of breath-hold challenges. This study assesses the repeatability of CVR measurements despite poor task performance, to determine if and how robust results could be achieved with breath-holds in patients. Twelve healthy volunteers were scanned at 3 T. Six functional scans were acquired, each consisting of 6 breath-hold challenges (10, 15, or 20 s duration) interleaved with periods of paced breathing. These scans simulated the varying breath-hold consistency and ability levels that may occur in patient data. Uniform ramps, time-scaled ramps, and end-tidal CO2 data were used as regressors in a general linear model in order to measure CVR at the grey matter, regional, and voxelwise level. The intraclass correlation coefficient (ICC) quantified the repeatability of the CVR measurement for each breath-hold regressor type and scale of interest across the variable task performances. The ramp regressors did not fully account for variability in breath-hold performance and did not achieve acceptable repeatability (ICC0.4). Further analysis of intra-subject CVR variability across the brain (ICCspatial and voxelwise correlation) supported the use of end-tidal CO2 data to extract robust whole-brain CVR maps, despite variability in breath-hold performance. We conclude that the incorporation of end-tidal CO2 monitoring into scanning enables robust, repeatable measurement of CVR that makes breath-hold challenges suitable for routine clinical practice. © 2013.

Survival and weight change among adult individuals of Periplaneta americana (Linnaeus, 1758 (Blattaria, Blattidae subject to various stress conditions

Directory of Open Access Journals (Sweden)

Jucelio Peter Duarte

2015-03-01

Full Text Available http://dx.doi.org/10.5007/2175-7925.2015v28n2p103 Periplaneta americana is a species of great importance to public health, since it can act as a vector of many pathogens and it reaches large populations in urban environments. This is probably due to its ability to resist starvation and desiccation. This study aimed to evaluate the effects of absence of water and food on survival and weight change among adult P. americana individuals and check whether the initial weight of individuals influences on their survival. Four groups having twenty P. americana couples were formed and subject to: I no water or food; II no food; III no water; and IV control group. Insects were isolated according to the groups, which were weighed at the beginning and end of the stress conditions. They remained under these conditions until all individuals in each test group were dead. Stress conditions caused reduction in survival time when compared to the control group. Adults with higher body mass survived longer when deprived only of food, while among those lacking water, weight had no influence on survival. Total weight loss was greater among individuals deprived of water than those deprived only of food.

The Effect of Inhalation Volume and Breath-Hold Duration on the Retention of Nicotine and Solanesol in the Human Respiratory Tract and on Subsequent Plasma Nicotine Concentrations During Cigarette Smoking

Directory of Open Access Journals (Sweden)

Armitage AK

2014-12-01

Full Text Available The influence of inhalation depth and breath-hold duration on the retention of nicotine and solanesol in the human respiratory tract and on nicotine uptake was studied in ten cigarette smokers. In a first series of experiments, the subjects took seven puffs from a 10 mg ‘tar’ yield, test cigarette and a fixed volume of air (0, 75, 250, 500 or 1000 mL, as required by the protocol was inhaled after each puff in order to give a controlled ‘depth’ of inhalation. The inhalation was drawn from a bag containing the required volume of air. Following a 2 s breath-hold, subjects exhaled normally, with the first exhalation after each puff passing through a single acidified filter pad for collection of the non-retained nicotine and solanesol. Blood samples were taken before and at intervals during and after smoking for the sessions with 0, 75 and 500 mL inhalation volumes for determination of plasma nicotine and carboxyhaemoglobin levels. Another series of experiments was conducted with a fixed inhalation volume (500 mL and two further breath-hold durations (0 and 10 s in addition to 2 s from above. Nicotine and solanesol retentions were measured for each breath-hold condition. The amounts of nicotine retained within the respiratory system, expressed as a percentage of the amount taken into the mouth, were consistently higher than the corresponding values for solanesol in all five inhalation conditions (0-1000 mL, 2 s breath-hold. Nicotine retention increased from 46.5% at zero inhalation to 99.5% at 1000 mL inhalation (2 s breath-hold and from 98.0% at zero breath-hold to 99.9% at 10 s breath-hold (500 mL inhalation. Solanesol retention increased from 34.2% at zero inhalation volume to 71.9% at 1000 mL inhalation (2 s breath-hold and from 51.8% at zero breath-hold to 87.6% at 10 s breath-hold (500 mL inhalation. Plasma nicotine decreased from pre-smoking levels after zero inhalation indicating that the nicotine retained within the mouth was poorly

Older adults report greater emotional well-being than younger persons, yet negative stereotypes about aging are pervasive. Little is known about age group perceptions of emotion in adulthood, particularly for familiar persons. Thus, this project determined perceptions of general affect in familiar younger and older adults. In two studies, participants (Study 1, younger adult n = 123, older adult n = 43; Study 2, younger adult n = 34, midlife adult n = 41, older adult n = 16) provided self-report data about their affect in general, as well as reported on the affect of a familiar younger person (aged 18--34) and a familiar older person (aged 65 or older). Emotion scales assessed high- and low-arousal positive and negative affect. Results suggest a less favorable perception of emotion experiences of older adults compared to younger adults. Specifically, participants of all age groups rated older adults as having lower positive emotions and higher negative emotions than is found in self-report data. Perceptions of emotion in older adulthood reflect stereotypes of negative functioning. Older adult participants were not immune to holding negative views about older adults. Negative perceptions about emotion experiences in later life may be detrimental to the physical and mental health of older adults.

The Dynamic contribution of chronic conditions to temporal trends in disability among U.S. adults.

Science.gov (United States)

Lin, Shih-Fan; Beck, Audrey N; Finch, Brian K

2016-04-01

Although evidence has shown that U.S. late-life disability has been declining, studies have also suggested that there has been an increase in chronic diseases between 1984 and 2007. To further illuminate these potentially contradictory trends, we explicate how the contribution of chronic conditions changes across four common types of disability (ADL, IADL, mobility disability, and functional limitations) by age (A), period (P), and birth cohorts (C) among adults aged 20 and above. Our data came from seven cross-sectional waves of the National Health and Nutrition Examination Survey (NHANES). We utilize a cross-classified random effect model (CCREM) to simultaneously estimate age, period, and cohort trends for each disability. Each chronic condition was sequentially then simultaneously added to our base models (sociodemographics only). Reductions in predicted probability from the base model were then calculated for each chronic condition by each temporal dimension (A/P/C) to assess the contribution of each chronic condition. There was increasing age-based contribution of chronic conditions to all disabilities. The period-based contribution remained quite stagnant across years while cohort-based contributions showed a continual decline for recent cohorts. Arthritis showed the greatest contribution to disability of all types which was followed by obesity. Cancer was the least important contributor to disabilities. Although chronic conditions are becoming less disabling across recent cohorts, other competing risk factors might suggest prevailing causes of disability. Copyright © 2016 Elsevier Inc.

Walker, Elizabeth Reisinger; Druss, Benjamin G

2017-07-01

The health of individuals in the U.S.A. is increasingly being defined by complexity and multimorbidity. We examined the patterns of co-occurrence of mental illness, substance abuse/dependence, and chronic medical conditions and the cumulative burden of these conditions and living in poverty on self-rated health. We conducted a secondary data analysis using publically-available data from the National Survey on Drug Use and Health (NSDUH), which is an annual nationally-representative survey. Pooled data from the 2010-2012 NSDUH surveys included 115,921 adults 18 years of age or older. The majority of adults (52.2%) had at least one type of condition (mental illness, substance abuse/dependence, or chronic medical conditions), with substantial overlap across the conditions. 1.2%, or 2.2 million people, reported all three conditions. Generally, as the number of conditions increased, the odds of reporting worse health also increased. The likelihood of reporting fair/poor health was greatest for people who reported AMI, chronic medical conditions, and poverty (AOR = 9.41; 95% CI: 7.53-11.76), followed by all three conditions and poverty (AOR = 9.32; 95% CI: 6.67-13.02). For each combination of conditions, the addition of poverty increased the likelihood of reporting fair/poor health. Traditional conceptualizations of multimorbidity should be expanded to take into account the complexities of co-occurrence between mental illnesses, chronic medical conditions, and socioeconomic factors.

2010-01-01

Purpose: To evaluate intra- and interfraction variability of tumor and lung volume and position using a hybrid active breath-hold gating technique. Methods and Materials: A total of 159 repeat normal inspiration active breath-hold CTs were acquired weekly during radiotherapy for 9 lung cancer patients (12-21 scans per patient). A physician delineated the gross tumor volume (GTV), lungs, and spinal cord on the first breath-hold CT, and contours were propagated semiautomatically. Intra- and interfraction variability of tumor and lung position and volume were evaluated. Tumor centroid and border variability were quantified. Results: On average, intrafraction variability of lung and GTV centroid position was 0.1). Increases in free-breathing tidal volume were associated with increases in breath-hold ipsilateral lung volume (p < 0.05). Conclusions: The breath-hold technique was reproducible within 2 mm during each fraction. Interfraction variability of GTV position and shape was substantial because of tumor volume and breath-hold lung volume change during therapy. These results support the feasibility of a hybrid breath-hold gating technique and suggest that online image guidance would be beneficial.

Breath-hold duration in man and the diving response induced by face immersion.

Science.gov (United States)

Sterba, J A; Lundgren, C E

1988-09-01

The objective of this study in 5 selected volunteer subjects was to see whether the circulatory diving response which is elicited by breath holding and by cold water on the face would affect the duration of maximal-effort breath holds. Compared to control measurements (breath holding during resting, breathing with 35 degrees C water on the face) breath holding with the face cooled by 20 degrees C water caused a 12% reduction of heart rate, 6% reduction of cardiac output, 33% reduction in [corrected] forearm blood flow, and 9% rise in mean arterial blood pressure, but there was no difference in breath-hold duration (control and experimental both 94 s). There were also no differences in time of appearance of the first involuntary respiratory efforts during breath holding, in alveolar gas exchange, or in breaking-point alveolar O2 and CO2 tensions. When the diving response was magnified by a brief bout of exercise so that there was a 19% [corrected] reduction in heart rate, 23% reduction in cardiac output, and 48% reduction in forearm blood flow, breath-hold duration was still unaffected by face cooling. Compared to intermittent immersions, continuous exposure of the face to cold water abolished the diving response, probably by a cold adaptation of facial thermal receptors. These results with cooling of the face only are consistent with our earlier finding that there was a negative correlation between the duration of a maximal-effort breath hold and the diving response during whole-body submersion in cold water.

Healthy older adults have insufficient hip range of motion and plantar flexor strength to walk like healthy young adults.

Science.gov (United States)

Anderson, Dennis E; Madigan, Michael L

2014-03-21

Limited plantar flexor strength and hip extension range of motion (ROM) in older adults are believed to underlie common age-related differences in gait. However, no studies of age-related differences in gait have quantified the percentage of strength and ROM used during gait. We examined peak hip angles, hip torques and plantar flexor torques, and corresponding estimates of functional capacity utilized (FCU), which we define as the percentage of available strength or joint ROM used, in 10 young and 10 older healthy adults walking under self-selected and controlled (slow and fast) conditions. Older adults walked with about 30% smaller hip extension angle, 28% larger hip flexion angle, 34% more hip extensor torque in the slow condition, and 12% less plantar flexor torque in the fast condition than young adults. Older adults had higher FCU than young adults for hip flexion angle (47% vs. 34%) and hip extensor torque (48% vs. 27%). FCUs for plantar flexor torque (both age groups) and hip extension angle (older adults in all conditions; young adults in self-selected gait) were not significantly adults lacked sufficient hip extension ROM to walk with a hip extension angle as large as that of young adults. Similarly, in the fast gait condition older adults lacked the strength to match the plantar flexor torque produced by young adults. This supports the hypothesis that hip extension ROM and plantar flexor strength are limiting factors in gait and contribute to age-related differences in gait. Copyright © 2014 Elsevier Ltd.

2018-03-01

Repeated apneas are associated with severe hypoxemia that may ultimately lead to loss of consciousness in some breath-hold divers. Despite increasing number of practitioners, the relationship between apnea-induced hypoxia and neurocognitive functions is still poorly understood in the sport of free diving. To shed light onto this phenomenon, we examined the impact of long-term breath-hold diving training on attentional processing, short-term memory, and long-term mnesic and executive functions. Thirty-six men matched for age, height, and weight were separated into the following 3 groups: (i) 12 elite breath-hold divers (EBHD), mean static apnea best time 371 s, 105 months mean apnea experience; (ii) 12 novice breath-hold divers, mean best time 243 s, 8.75 months mean apnea experience; and (iii) 12 physical education students with no breath-hold diving experience; all of these participants performed varied written and computerized neuropsychological tasks. Compared with the 2 other groups, the EBHD group was slower to complete the interference card during a Stroop test (F [1,33] = 4.70, p short-term memory impairments.

Full Text Available The aim of this study is to examine the effect of the global financial crisis and firm characteristics on corporate cash holdings in Indonesia. A total of 101 manufacturing firms listed in the Indonesia Stock Exchange from 2005 to 2014 are examined. This study employs panel regression with fixed effect model. The results show that Indonesia firms hold more cash during the global financial crisis than in the normal times. Investment opportunities set and divident payment have positive effect on cash holding, meanwhile firm size, capital expenditure, liquid assets substitutes, and leverage have negative effect on cash holding. 

Can we still beat "buy-and-hold" for individual stocks?

Science.gov (United States)

Hui, Eddie C. M.; Kevin Chan, Ka Kwan

2014-09-01

Many investors seek for a trading strategy to beat the "buy-and-hold" strategy. In light of this, Hui and Yam (2014) and Hui et al. (2014) derived a trading strategy from the Shiryaev-Zhou index, and found that the resulting strategy outperformed the "buy-and-hold" strategy for western and Asian securitized real estate indices respectively. However, whether the trading strategy works on individual stocks or not is still unknown. This is the first study to test whether the trading strategy can beat the "buy-and-hold" strategy on individual stocks. We construct two trading strategies and compare the resulting profits with the profits arising from the "buy-and-hold" strategy on Hang Seng Index (HSI), Hang Seng Property (HSP) Index and 12 constituent stocks of HSI during the period December 29, 1995-December 31, 2013. The second strategy (Strategy 2) is a new strategy which incorporates short-selling, and has the effect of multiplying the profit. The results show that our trading strategies are less effective on individual stocks than on stock indices, and are more effective on property stocks than on non-property stocks. Moreover, our strategies outperform "buy-and-hold" by a larger extent on stocks of which the Shiryaev-Zhou indices fluctuate less frequently. Furthermore, by tracking the resulting profits of the three strategies at different times along the whole period of observation, our strategies work better during "bad times" than during "good times". This reflects that our trading strategies are especially useful in protecting investors from substantial loss during market downturns.

Conditional reduction of adult born doublecortin-positive neurons reversibly impairs selective behaviours

Full Text Available Adult neurogenesis occurs in the adult mammalian subventricular zone (SVZ along the walls of the lateral ventricles and the subgranular zone (SGZ of the hippocampal dentate gyrus. While a burgeoning body of research implicates adult neurogenesis in olfactory bulb (OB - and hippocampal-related behaviors, the precise function continues to elude. To further assess the behavioral importance of adult neurogenesis, we herein generated a novel inducible transgenic mouse model of adult neurogenesis reduction where mice with CreERT2 under doublecortin (DCX promoter control were crossed with mice where diphtheria toxin A (DTA was driven by the Rosa26 promoter. Activation of DTA, through the administration of tamoxifen (TAM, results in a specific reduction of DCX+ immature neurons in both the hippocampal dentate gyrus and OB. We show that the decrease of DCX+ cells causes impaired social discrimination ability in both young adult (from 3 months and middle (from 10 months aged mice. Furthermore, these animals showed an age-independent altered coping behavior in the Forced Swim Test without clear changes in anxiety-related behavior. Notably, these behavior changes were reversible on repopulating the neurogenic zones with DCX+ cells on cessation of the tamoxifen treatment, demonstrating the specificity of this effect. Overall, these results support the notion that adult neurogenesis plays a role in social memory and in stress coping but not necessarily in anxiety-related behavior.

Current treatments for renal cell carcinoma have a high complication rate due to the invasiveness of the treatment. With the MRI-linac it may be possible to treat renal tumours non-invasively with high-precision radiotherapy. This is expected to reduce complications. To deliver a static dose distribution, radiation gating will be used. In this study the reproducibility and efficiency of free breathing gating and a breath hold treatment of the kidney was investigated. For 15 patients with a renal lesion the kidney motion during 2 min of free breathing and 10 consecutive expiration breath holds was studied with 2D cine MRI. The variability in kidney expiration position and treatment efficiency for gating windows of 1 to 20 mm was measured for both breathing patterns. Additionally the time trend in free breathing and the variation in expiration breath hold kidney position with baseline shift correction was determined. In 80% of the patients the variation in expiration position during free breathing is smaller than 2 mm. No clinically relevant time trends were detected. The variation in expiration breath hold is for all patients larger than the free breathing expiration variation. Gating on free breathing is, for gating windows of 1 to 5 mm more efficient than breath hold without baseline correction. When applying a baseline correction to the breath hold it increases the treatment efficiency. The kidney position is more reproducible in expiration free breathing than non-guided expiration breath hold. For small gating windows it is also more time efficient. Since free breathing also seems more comfortable for the patients it is the preferred breathing pattern for MRI-Linac treatments of the kidney. (paper)

Preformed stainless steel crown in special conditions in adults: Two case reports

Directory of Open Access Journals (Sweden)

S Madhu

2015-01-01

Full Text Available Stainless steel crowns (SSC are extensively used in child patients. They are mainly used following the pulp therapy in deciduous teeth. They are also used in multi-surface restoration, as an abutment in space maintainers, correction of anterior tooth cross bite, restoration of hypoplasic teeth, etc. In permanent teeth, they are mainly used as interim restorations following root canal treatment in first molars prior to the eruption of permanent second molars. The main advantage of SSC is its limited chair side time, durability and ease of placement. Patients with conditions such as pregnancy and old age who cannot tolerate multiple and long appointments can greatly benefit from the use of SSC. Though SSC can be used by other dental specialties very effectively, its use seems to be limited to pediatric dentistry. Presented here are few adult cases in which SSC is given with good success.

Transcriptomics reveal transgenerational effects in purple sea urchin embryos: Adult acclimation to upwelling conditions alters the response of their progeny to differential pCO2 levels.

Wong, Juliet M; Johnson, Kevin M; Kelly, Morgan W; Hofmann, Gretchen E

2018-03-01

Understanding the mechanisms with which organisms can respond to a rapidly changing ocean is an important research priority in marine sciences, especially in the light of recent predictions regarding the pace of ocean change in the coming decades. Transgenerational effects, in which the experience of the parental generation can shape the phenotype of their offspring, may serve as such a mechanism. In this study, adult purple sea urchins, Strongylocentrotus purpuratus, were conditioned to regionally and ecologically relevant pCO 2 levels and temperatures representative of upwelling (colder temperature and high pCO 2 ) and nonupwelling (average temperature and low pCO 2 ) conditions typical of coastal upwelling regions in the California Current System. Following 4.5 months of conditioning, adults were spawned and offspring were raised under either high or low pCO 2 levels, to examine the role of maternal effects. Using RNA-seq and comparative transcriptomics, our results indicate that differential conditioning of the adults had an effect on the gene expression patterns of the progeny during the gastrula stage of early development. For example, maternal conditioning under upwelling conditions intensified the transcriptomic response of the progeny when they were raised under high versus low pCO 2 conditions. Additionally, mothers that experienced upwelling conditions produced larger progeny. The overall findings of this study are complex, but do suggest that transgenerational plasticity in situ could act as an important mechanism by which populations might keep pace with rapid environmental change. © 2018 John Wiley & Sons Ltd.

Given the high number of young adults caring for a family member, and the potential for adverse psychosocial outcomes, there is a need for a screening tool, with clinical utility, to identify those most vulnerable to poor outcomes and to aid targeted interventions. (i) To determine whether current knowledge from cancer literature regarding young carers is generalisable to chronic conditions and, therefore, whether an existing screening tool could be adapted for this population. (ii) To develop a measure of unmet needs in this population and conduct initial psychometric analysis. This was mixed method; interviews in study one informed measure development in study two. Inclusion criteria were as follows: having a parent with a chronic condition and being aged 16-24 years. In study 1, an interpretative phenomenological analysis was conducted on interviews from seven young adults (age range 17-19 years). Study 2 explored factor structure, reliability and validity of the Offspring Chronic Illness Needs Inventory (OCINI). Participants were 73 females and 34 males (mean ages 18.22, SD = 1.16; 18.65, SD = 1.25). OCINI, Depression Anxiety and Stress Scale, and the Adult Carers Quality of Life Scale. Interviews communicated that the impact of their parent's condition went unacknowledged and resulted in psychosocial, support and informational needs. An exploratory principal axis analysis of the OCINI yielded five factors. Significant and positive correlations were found between unmet needs and stress, anxiety, and depression, and inversely with quality of life. The scale has applications in clinical settings where these young people, who are at risk of negative psychological outcomes, may be assessed and unmet needs targeted appropriately. © 2016 Nordic College of Caring Science.

Effects of Adult Feeding and Overwintering Conditions on Energy Reserves and Flight Performance of Emerald Ash Borer (Coleoptera: Buprestidae).

Emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive beetle from Asia, spreads through human-mediated movement and active flight. The effects of adult feeding and overwintering conditions on A. planipennis energy reserves (e.g., lipid, glycogen, and sugars) and flight are poorly understood. We conjectured that the potential energetic demands associated with the production of cryoprotectants might affect dispersal capacity and partially explain slower spread of A. planipennis in Minnesota than in the other states. Two studies sought to measure the effects of adult feeding on lipid content and flight capacity. Adult A. planipennis were fed shamel ash, Fraxinus uhdei Wenzig, leaves for 0-20 d after emergence, and half were flown on a custom flight mill for 24 h, before being frozen for comparative lipid analysis with a control group. The second study compared the effects of adult feeding on energy reserves and flight capacity of A. planipennis that were originally from St. Paul, Minnesota but overwintered in infested logs placed in Grand Rapids, Minnesota (low winter temperature, -34°C) or St. Paul, Minnesota (-26.3°C). Live adults consumed foliage at a constant rate, but lipid content (percentage of fresh mass) did not change with increases in feeding or flight. Adult glycogen content declined with flight and increased only slightly with feeding. Overwintering location affected survival rates but not energy reserves or flight capacity. These results suggest that the flight capacity of A. planipennis is largely determined before emergence, with no differences in energy reserves after cryoprotectant investment.

Step voltage with periodic hold-up etching: A novel porous silicon formation

International Nuclear Information System (INIS)

Naddaf, M.; Awad, F.; Soukeih, M.

2007-01-01

A novel etching method for preparing light-emitting porous silicon (PS) is developed. A gradient steps (staircase) voltage is applied and hold-up for different periods of time between p-type silicon wafers and a graphite electrode in HF based solutions periodically. The single applied staircase voltage (0-30 V) is ramped in equal steps of 0.5 V for 6 s, and hold at 30 V for 30 s at a current of 6 mA. The current during hold-up time (0 V) was less than 10 μA. The room temperature photoluminescence (PL) behavior of the PS samples as a function of etching parameters has been investigated. The intensity of PL peak is initially increased and blue shifted on increasing etching time, but decreased after prolonged time. These are correlated with the study of changes in surface morphology using atomic force microscope (AFM), porosity and electrical conductance measurements. The time of holding-up the applied voltage during the formation process is found to highly affect the PS properties. On increasing the holding-up time, the intensity of PL peak is increased and blue shifted. The contribution of holding-up the applied steps during the formation process of PS is seen to be more or less similar to the post chemical etching process. It is demonstrated that this method can yield a porous silicon layer with stronger photoluminescence intensity and blue shifted than the porous silicon layer prepared by DC etching

The Economics of an Admissions Holding Unit.

2017-06-01

With increasing attention to the actual cost of delivering care, return-on-investment calculations take on new significance. Boarded patients in the emergency department (ED) are harmful to clinical care and have significant financial opportunity costs. We hypothesize that investment in an admissions holding unit for admitted ED patients not only captures opportunity cost but also significantly lowers direct cost of care. This was a three-phase study at a busy urban teaching center with significant walkout rate. We first determined the true cost of maintaining a staffed ED bed for one patient-hour and compared it to alternative settings. The opportunity cost for patients leaving without being seen was then conservatively estimated. Lastly, a convenience sample of admitted patients boarding in the ED was observed continuously from one hour after decision-to-admit until physical departure from the ED to capture a record of every interaction with a nurse or physician. Personnel costs per patient bed-hour were $58.20 for the ED, $24.80 for an inpatient floor, $19.20 for the inpatient observation unit, and $10.40 for an admissions holding area. An eight-bed holding unit operating at practical capacity would free 57.4 hours of bed space in the ED and allow treatment of 20 additional patients. This could yield increased revenues of $27,796 per day and capture opportunity cost of $6.09 million over 219 days, in return for extra staffing costs of $218,650. Analysis of resources used for boarded patients was determined by continuous observation of a convenience sample of ED-boarded patients, which found near-zero interactions with both nursing and physicians during the boarding interval. Resource expense per ED bed-hour is more than twice that in non-critical care inpatient units. Despite the high cost of available resources, boarded non-critical patients receive virtually no nursing or physician attention. An admissions holding unit is remarkably effective in avoiding the

2015-09-01

The physiology of breath holding is complex, and voluntary breath-hold duration is affected by many factors, including practice, psychology, respiratory chemoreflexes, and lung stretch. In this activity, we outline a number of simple laboratory activities or classroom demonstrations that illustrate the complexity of the integrative physiology behind breath-hold duration. These activities require minimal equipment and are easily adapted to small-group demonstrations or a larger-group inquiry format where students can design a protocol and collect and analyze data from their classmates. Specifically, breath-hold duration is measured during a number of maneuvers, including after end expiration, end inspiration, voluntary prior hyperventilation, and inspired hyperoxia. Further activities illustrate the potential contribution of chemoreflexes through rebreathing and repeated rebreathing after a maximum breath hold.

Refractories materials characterization for aluminum melting and holding furnaces: an alternative for a better performance

International Nuclear Information System (INIS)

Novo, M.M.M.; Pandolfelli, V.C.

2011-01-01

The industrial needs in reducing the energy consumption is part of a continuing search towards higher levels of sustainability and competitiveness. Considering these aspects, the aluminum industry seeks new alternatives for a better performance of aluminum melting and holding furnaces and this aim is directly dependent on the refractory materials ability to conserve heat and withstand the mechanical, chemical and thermal degradation processes. This paper presents the thermo-mechanical characterization of five aluminous dense commercial refractory (average density of 2.7 g / cm ³), used in such equipment. The results indicated that choosing the most suitable composition requires the evaluation of the microstructure aspects, such as porosity, permeability and pore size, and also the refractory's physical integrity, such as thermal shock resistance, abrasion resistance and high temperature modulus of rupture. The laboratory tests allowed the characterization of all the materials at the same conditions. Moreover, it was possible to optimize the selection of lining materials for melting and holding furnaces and to provide basis to a possible costs improvements synergy. (author)

Framing effects in younger and older adults.

Science.gov (United States)

Kim, Sunghan; Goldstein, David; Hasher, Lynn; Zacks, Rose T

2005-07-01

A growing literature on decision making in older adults suggests that they are more likely to use heuristic processing than are younger adults. We assessed this tendency in the context of a framing effect, a decision-making phenomenon whereby the language used to describe options greatly influences the decision maker's choice. We compared decision making under a standard ("heuristic") condition and also under a "justification" condition known to reduce reliance on heuristics. In the standard condition, older adults were more susceptible than younger adults to framing but the two groups did not differ when participants were asked to provide a justification. Thus, although older adults may spontaneously rely more on heuristic processing than younger adults, they can be induced to take a more systematic approach to decision making.

Adult height, nutrition, and population health

Perkins, Jessica M.; Subramanian, S.V.; Davey Smith, George

2016-01-01

In this review, the potential causes and consequences of adult height, a measure of cumulative net nutrition, in modern populations are summarized. The mechanisms linking adult height and health are examined, with a focus on the role of potential confounders. Evidence across studies indicates that short adult height (reflecting growth retardation) in low- and middle-income countries is driven by environmental conditions, especially net nutrition during early years. Some of the associations of height with health and social outcomes potentially reflect the association between these environmental factors and such outcomes. These conditions are manifested in the substantial differences in adult height that exist between and within countries and over time. This review suggests that adult height is a useful marker of variation in cumulative net nutrition, biological deprivation, and standard of living between and within populations and should be routinely measured. Linkages between adult height and health, within and across generations, suggest that adult height may be a potential tool for monitoring health conditions and that programs focused on offspring outcomes may consider maternal height as a potentially important influence.

Full Text Available Falls are an important health concern among older adults due to age-related changes in the body. Having a medical history of chronic health condition may pose even higher risk of falling. Only few studies have assessed a number of chronic health conditions as risk factor for falls over a large nationally representative sample of US older adults. In this study, Behavioral Risk Factor Surveillance System (BRFSS 2014 participants aged 65 years and older (n = 159,336 were evaluated. It was found that 29.7% (n=44,550 of the sample experienced at least one fall and 16.3% (n=20,444 experienced more than one fall in the past 12 months. According to the study findings, having a medical history of stroke, CKD, arthritis, depression, and diabetes independently predict the risk of first-time falling as well as the risk of recurrent falling in older adult population while controlling for other factors. On the other hand, having a medical history of the heart attack, angina, asthma, and COPD did not predict the risk of first-time falling, but did predict the risk of recurrent falling after experiencing the first fall in this population.

A conceptual holding model for veterinary applications

Directory of Open Access Journals (Sweden)

Nicola Ferrè

2014-05-01

Full Text Available Spatial references are required when geographical information systems (GIS are used for the collection, storage and management of data. In the veterinary domain, the spatial component of a holding (of animals is usually defined by coordinates, and no other relevant information needs to be interpreted or used for manipulation of the data in the GIS environment provided. Users trying to integrate or reuse spatial data organised in such a way, frequently face the problem of data incompatibility and inconsistency. The root of the problem lies in differences with respect to syntax as well as variations in the semantic, spatial and temporal representations of the geographic features. To overcome these problems and to facilitate the inter-operability of different GIS, spatial data must be defined according to a “schema” that includes the definition, acquisition, analysis, access, presentation and transfer of such data between different users and systems. We propose an application “schema” of holdings for GIS applications in the veterinary domain according to the European directive framework (directive 2007/2/EC - INSPIRE. The conceptual model put forward has been developed at two specific levels to produce the essential and the abstract model, respectively. The former establishes the conceptual linkage of the system design to the real world, while the latter describes how the system or software works. The result is an application “schema” that formalises and unifies the information-theoretic foundations of how to spatially represent a holding in order to ensure straightforward information-sharing within the veterinary community.

Energy conditions and spacetime singularities

International Nuclear Information System (INIS)

Tipler, F.J.

1978-01-01

In this paper, a number of theorems are proven which collectively show that singularities will occur in spacetime under weaker energy conditions than the strong energy condition. In particular, the Penrose theorem, which uses only the weak energy condition but which applies only to open universes, is extended to all closed universes which have a Cauchy surface whose universal covering manifold is not a three-sphere. Furthermore, it is shown that the strong energy condition in the Hawking-Penrose theorem can be replaced by the weak energy condition and the assumption that the strong energy condition holds only on the average. In addition, it is demonstrated that if the Universe is closed, then the existence of singularities follows from the averaged strong energy condition alone. It is argued that any globally hyperbolic spacetime which satisfies the weak energy condition and which contains a black hole must be null geodesically incomplete

Migrant screening: Lessons learned from the migrant holding level at the Greek-Turkish borders.

Eonomopoulou, Assimoula; Pavli, Androula; Stasinopoulou, Panagiota; Giannopoulos, Lambros A; Tsiodras, Sotirios

In March 2011, a migrant health project became operational that aimed to provide medical and psychosocial support to migrants at the Greek-Turkish border. The aim of this study is to describe common syndromes, the communicable disease profile and vaccination patterns in newly arrived migrants through a surveillance system that was based on medical records data as well as screening procedures. Data were collected prospectively using one standardized form per patient including demographic information, civil status, and medical and vaccination history. A tuberculin screening test (TST) and serological testing for HIV, hepatitis B and hepatitis C were performed after obtaining informed consent. A total of 6899 migrants were screened, the majority of whom were male (91%) and 18-31 years old (85%), with a mean age of 25.3 years. Of all patients, 2.5% received secondary care. Common complaints and diagnoses included respiratory infections (23%) and myalgia (18%). The tuberculin screening test (TST) was positive in 7.8% out of 1132 patients tested. Out of 632 migrants, 0.3%, 3.2% and 0.8% tested positive for HIV, hepatitis B and hepatitis C, respectively. Overall, 22.3% of adults were vaccinated against poliomyelitis. Irregular migrants that enter Greek borders are generally in good health. Nevertheless, the risk of spreading communicable diseases is an important issue to consider among migrants at the holding level due to severe overcrowding conditions. Therefore, there is a need to strengthen surveillance and implement harmonized screening procedures with the aim of providing sustainable and good quality services that are focused on prevention and early treatment.

2018-03-01

Drought conditions and nutrients loss have serious impacts on soil quality as well as crop yields in agroecosystems. New techniques are needed to carry out effective soil water and nutrient conservation and fertilizer application tools. Here, calcium alginate (CA) beads impregnated with ball-milled biochar (BMB) were investigated as a new type of water/nutrients retention agent. Both CA and Ca-alginate/ball milled biochar composite (CA-BMB) beads showed high kinetic swelling ratios in KNO 3 solution and low kinetic swelling ratios in water, indicating that CA-BMB beads have the potential to retain mineral nitrogen and nutrients by ion exchange. Pseudo-second-order kinetic model well-described the swelling kinetics of both beads in KNO 3 solution. Over a range of temperatures, the characteristics of dehydration suggested that impregnation with BMB improved the water holding capacity and postponed the dehydration time of Ca-alginate. The cumulative swelling and release characteristics of water, K + , and NO 3 - indicated that CA-BMB beads have great potential as a soil amendment to improve its nutrient retention and water holding capacity.

A behavioral comparison of male and female adults with high functioning autism spectrum conditions.

Directory of Open Access Journals (Sweden)

Meng-Chuan Lai

Full Text Available Autism spectrum conditions (ASC affect more males than females in the general population. However, within ASC it is unclear if there are phenotypic sex differences. Testing for similarities and differences between the sexes is important not only for clinical assessment but also has implications for theories of typical sex differences and of autism. Using cognitive and behavioral measures, we investigated similarities and differences between the sexes in age- and IQ-matched adults with ASC (high-functioning autism or Asperger syndrome. Of the 83 (45 males and 38 females participants, 62 (33 males and 29 females met Autism Diagnostic Interview-Revised (ADI-R cut-off criteria for autism in childhood and were included in all subsequent analyses. The severity of childhood core autism symptoms did not differ between the sexes. Males and females also did not differ in self-reported empathy, systemizing, anxiety, depression, and obsessive-compulsive traits/symptoms or mentalizing performance. However, adult females with ASC showed more lifetime sensory symptoms (p = 0.036, fewer current socio-communication difficulties (p = 0.001, and more self-reported autistic traits (p = 0.012 than males. In addition, females with ASC who also had developmental language delay had lower current performance IQ than those without developmental language delay (p<0.001, a pattern not seen in males. The absence of typical sex differences in empathizing-systemizing profiles within the autism spectrum confirms a prediction from the extreme male brain theory. Behavioral sex differences within ASC may also reflect different developmental mechanisms between males and females with ASC. We discuss the importance of the superficially better socio-communication ability in adult females with ASC in terms of why females with ASC may more often go under-recognized, and receive their diagnosis later, than males.

Financial penalties for the unhealthy? Ethical guidelines for holding employees responsible for their health.

Science.gov (United States)

Pearson, Steven D; Lieber, Sarah R

2009-01-01

As health care costs continue to rise, an increasing number of self-insured employers are using financial rewards or penalties to promote healthy behavior and control costs. These incentive programs have triggered a backlash from those concerned that holding employees responsible for their health, particularly through the use of penalties, violates individual liberties and discriminates against the unhealthy. This paper offers an ethical analysis of employee health incentive programs and presents an argument for a set of conditions under which penalties can be used in an ethical and responsible way to contain health care costs and encourage healthy behavior among employees.

Interference from previous distraction disrupts older adults' memory.

Science.gov (United States)

Biss, Renée K; Campbell, Karen L; Hasher, Lynn

2013-07-01

Previously relevant information can disrupt the ability of older adults to remember new information. Here, the researchers examined whether prior irrelevant information, or distraction, can also interfere with older adults' memory for new information. Younger and older adults first completed a 1-back task on pictures that were superimposed with distracting words. After a delay, participants learned picture-word paired associates and memory was tested using picture-cued recall. In 1 condition (high interference), some pairs included pictures from the 1-back task now paired with new words. In a low-interference condition, the transfer list used all new items. Older adults had substantially lower cued-recall performance in the high- compared with the low-interference condition. In contrast, younger adults' performance did not vary across conditions. These findings suggest that even never-relevant information from the past can disrupt older adults' memory for new associations.

Diverse Presentation of Breath Holding Spells: Two Case Reports with Literature Review

Directory of Open Access Journals (Sweden)

Geetanjali Rathore

2013-01-01

Full Text Available Breath holding spells are a common and dramatic form of syncope and anoxic seizure in infancy. They are usually triggered by an emotional stimuli or minor trauma. Based on the color change, they are classified into 3 types, cyanotic, pallid, and mixed. Pallid breath holding spells result from exaggerated, vagally-mediated cardiac inhibition, whereas the more common, cyanotic breathholding spells are of more complex pathogenesis which is not completely understood. A detailed and accurate history is the mainstay of diagnosis. An EKG should be strongly considered to rule out long QT syndrome. Spontaneous resolution of breath-holding spells is usually seen, without any adverse developmental and intellectual sequelae. Rare cases of status epilepticus, prolonged asystole, and sudden death have been reported. Reassurance and education is the mainstay of therapy. Occasionally, pharmacologic intervention with iron, piracetam; atropine may be of benefit. Here we present 2 cases, one of each, pallid and cyanotic breath holding spells.

Effects of heavy metal exposure on the condition and health of adult great tits (Parus major)

International Nuclear Information System (INIS)

Dauwe, Tom; Janssens, Ellen; Eens, Marcel

2006-01-01

We examined the possible effects of heavy metal exposure on the quality and health of adult great tits (Parus major) at four study sites along a pollution gradient near a non-ferrous smelter in Belgium. Tarsus length, wing length, body mass and condition of great tits were compared with respect to study site, age (first-year and older great tits), sex and season (birds caught in winter and during breeding). Tarsus length did not differ significantly among study sites. The wing length of great tits was larger at the study site furthest from the smelter, especially for older great tits. The length of the outermost tail feathers, however, did not differ significantly among study sites. We found no signs of loss of body mass or condition towards the pollution source. The body mass and condition was lowest for female great tits at the site furthest from the smelter, especially during winter. Haematocrit values did not differ significantly among sites. Overall, we found no clear significant effects of heavy metal pollution on morphological measurements and health parameters of great tits. - Heavy metal pollution had no clear effect on condition and health, but this may have been masked by habitat quality differences and gene flow

Using Generalized Least Square (GLS) method for regression analysis, the results show that holding either tier-1 or tier- 2 of CRC significantly and positively results in conducting research with higher impact. This finding, however, does not necessarily imply that the others are the lesser scientists. (Author)

Environmental and ecological conditions at Arctic breeding sites have limited effects on true survival rates of adult shorebirds

2018-01-01

Many Arctic shorebird populations are declining, and quantifying adult survival and the effects of anthropogenic factors is a crucial step toward a better understanding of population dynamics. We used a recently developed, spatially explicit Cormack–Jolly–Seber model in a Bayesian framework to obtain broad-scale estimates of true annual survival rates for 6 species of shorebirds at 9 breeding sites across the North American Arctic in 2010–2014. We tested for effects of environmental and ecological variables, study site, nest fate, and sex on annual survival rates of each species in the spatially explicit framework, which allowed us to distinguish between effects of variables on site fidelity versus true survival. Our spatially explicit analysis produced estimates of true survival rates that were substantially higher than previously published estimates of apparent survival for most species, ranging from S = 0.72 to 0.98 across 5 species. However, survival was lower for the arcticolasubspecies of Dunlin (Calidris alpina arcticola; S = 0.54), our only study taxon that migrates through the East Asian–Australasian Flyway. Like other species that use that flyway, arcticola Dunlin could be experiencing unsustainably low survival rates as a result of loss of migratory stopover habitat. Survival rates of our study species were not affected by timing of snowmelt or summer temperature, and only 2 species showed minor variation among study sites. Furthermore, although previous reproductive success, predator abundance, and the availability of alternative prey each affected survival of one species, no factors broadly affected survival across species. Overall, our findings of few effects of environmental or ecological variables suggest that annual survival rates of adult shorebirds are generally robust to conditions at Arctic breeding sites. Instead, conditions at migratory stopovers or overwintering sites might be driving adult survival rates and should be the

2015-10-01

The present study evaluated intimacy as a mechanism for the effects of holding back sharing concerns about cancer on couples' psychological distress, well-being, and marital satisfaction using the actor-partner interdependence model (APIM), and evaluated 2 possible moderators of these associations: the number of patient and spouse cancer concerns. We had 139 men treated for localized prostate cancer in the past year and their spouses complete surveys about holding back sharing cancer concerns, intimacy, distress, and relationship satisfaction, as well as patient and spouse cancer concerns. APIM-indicated that the association between holding back sharing concerns, and patient and spouse distress, well-being, and relationship satisfaction could be partially accounted for by their influence on patient and spouse perceptions of relationship intimacy. The number of cancer concerns did not moderate the mediational model. Holding back has strong associations with both partners' well-being and distress. Holding back sharing concerns was particularly detrimental for couples' intimacy and relationship satisfaction. (c) 2015 APA, all rights reserved).

OpenAIRE

SHEN Yang; ZHAO Ning; LIU Haiwei; MI Chao

2013-01-01

Our paper represents a vision system based on the laser measurement system (LMS) for bulk ship inspection. The LMS scanner with 2-axis servo system is installed on the ship loader to build the shape of the ship. Then, a group of real-time image processing algorithms are implemented to compute the shape of the cargo hold, the inclination angle of the ship and the relative position between the ship loader and the cargo hold. Based on those computed inspection data of the ship, the ship loader c...

EXCESS CASH HOLDINGS DAN KEPEMILIKAN INSTITUSIONAL PADA PERUSAHAAN MANUFAKTUR YANG TERDAFTAR DI BEI

Yessica Tria Christina

2014-02-01

Full Text Available This research provides an empirical evidence about the effect of institutional ownerships as a proxy of information transparancy on excess cash holdings. Manufacture companies listed on BEI from years 2002 to 2011 are employed. The results show that the higher the proportion of institutional ownership, the lower the excess cash holdings. Informational transparancy, as one of the requirements of good corporate governance, can in fact lower the chance of aggrevating the manager’s behavior to practice excess cash holdings that can lower the company’s efficiency.

Radiotherapy of lung cancer: the inspiration breath hold with a spirometric monitoring

Garcia, R.; Oozeer, R.; Le Thanh, H.; Chastel, D.; Doyen, J.C.; Chauvet, B.; Reboul, F.

2002-01-01

A CT acquisition during a free breathing examination generates images of poor quality. It creates an uncertainty on the reconstructed gross tumour volume and dose distribution. The aim of this study is to test the feasibility of a breath hold method applied in all preparation and treatment days. Five patients received a thoracic radiotherapy with the benefit of this procedure. The breathing of the patient was measured with a spirometer. The patient was coached to reproduce a constant level of breath-hold in a deep inspiration. Video glasses helped the patients to fix the breath-hold at the reference level. The patients followed the coaching during preparation and treatment, without any difficulty. The better quality of the CT reconstructed images resulted in an easier contouring. No movements of the gross tumour volume lead to a better coverage. The deep breath hold decreased the volume of irradiated lung. This method improves the reproducibility of the thoracic irradiation. The decrease of irradiated lung volume offers prospects in dose escalation and intensity modulation radiotherapy. (authors)

Skin-to-skin holding in the neonatal intensive care unit influences maternal milk volume.

Hurst, N M; Valentine, C J; Renfro, L; Burns, P; Ferlic, L

1997-01-01

To evaluate the effect of early initiation of skin-to-skin (STS) holding on lactation, we compared 24-hour milk volumes of mothers of ventilated low birth weight infants in an STS group to mothers in a non-STS control group. Mean 24-hour milk volumes at 2, 3, and 4 weeks after delivery of mothers participating in STS holding were compared with those of a retrospective control group from the 12-month period immediately preceding the introduction of STS holding in the neonatal intensive care unit. A repeated-measures analysis of variance adjusting for baseline volumes (1 week after delivery) was used to evaluate the difference in milk volumes between STS and control groups. Sixteen mothers initiated STS holding during the 2-month study period. Eight mothers met study criteria by initiating STS holding during the first 4 weeks after delivery. During a 2-week period the study group had a strong linear increase in milk volume in contrast to no indicative change of the control group's milk volume. STS holding of low birth weight infants initiated in the early intensive care phase can result in a significant increase in maternal milk volume, thereby overcoming the frequently seen insufficient lactation experienced by these mothers.

Analysis of cash holding for measuring the efficiency of cash management: A study on IT sector

Directory of Open Access Journals (Sweden)

Somnath Das

2015-01-01

Full Text Available For measuring the efficiency of management of cash, cash holding is one of the most important financial decisions that the manager of the concerned organization, has to make in the organization. Basically, it is observed that the organization hold cash for future purposes is very negligible. If the organization invested cash in profitable securities then there is some flexibility but when it relates to the capital market holding cash is not advantageous. Generally two contradictory theories such as Trade-off theory and the Pecking order theory are considered for measuring the efficiency of cash management. In this study we generally observed measured the efficiency of Cash Management influenced by Cash Holding. We also measured whether cash holding of the organization is affected with the degree of financial leverage, size of the organization, investment and profitability. This study helps us to understand the influence of DFL, Investment and Size of the organization on Cash holding. Proper holding of cash in cash management can prevent the bankruptcy of any organization and also increases the efficiency of Cash or Liquidity management.

Morteza Ghojazadeh

2015-12-01

Full Text Available Introduction: Due to the importance of holding effective scientific Olympiads for medical sciences students, this study aimed to evaluate experts’ viewpoints in regard to their necessity, costs, achievements, barriers and solutions. Methods: In this qualitative study, required data were collected using open-ended questions through self-development questionnaires, which were filled out by experts. Data were analyzed through content-analysis methods. To select participants, a purpose-based sampling method was applied up to the point of information saturation. Thus, this study was performed with 20 individuals. Results: The main necessity and philosophy of holding Olympiads expressed by the experts were: promoting health sector performance, extension of interrelationships between universities, development of scientific competition and incensement of students’ creativity. The majority of participants believed that the achievements of holding these Olympiads are negligible versus their costs. The most important barriers were: absence of appropriate relationships between universities, lack of proper support for holding these Olympiads, the low motivation of professors, noninterested students and the shortage of resources and facilities. Furthermore, the most important solutions included: performance evaluation of previous Olympiads, increasing incentives and motivations as well as suitable planning. Conclusion: According to experts’ viewpoints, although holding scientific Olympiads is necessary for medical students, during past years, the achievements of such Olympiads versus theirs costs seem negligible and there are lots of barriers in the path of achieving their goals and philosophy.

Evaluation of outcome measures for use in clinical practice for adults with musculoskeletal conditions of the knee: a systematic review.

Science.gov (United States)

Howe, Tracey E; Dawson, Lesley J; Syme, Grant; Duncan, Louise; Reid, Judith

2012-04-01

This systematic review reported on the clinimetric properties of outcome measures for use in clinical practice for adults with musculoskeletal conditions of the knee. A systematic search was performed in Medline, EMBASE, Cinahl and AMED to identify studies examining the clinimetric properties of outcome measures for adults undergoing conservative treatment of ligament injuries, meniscal lesions, patellofemoral pain and osteoarthritis of the knee. Outcomes measures taking less than 20 min to administer and requiring minimal equipment and space were included. Pairs of authors used a checklist to record the characteristics of the outcome measures, their reported clinimetric properties and the demographics of the study populations. The OMERACT filters of 'truth' and 'discrimination' were applied to the data for each outcome measure by an expert panel. Forty-seven studies were included evaluating 37 outcome measures. Ten outcome measures had adequate supporting evidence for 'truth' and 'discrimination': AAOS, AKPS, goniometer measurement, IKDC, KOOS, LEFS, Lysholm, Tegner, WOMAC and WOMET. However none of the outcome measures had been comprehensively tested across all clinimetric properties. Despite the widespread use of some outcome measures in clinical practice and primary research, data on the clinimetric properties were available for only 37 and of these only 10 had adequate supporting evidence for use in this population. However, before a core set of outcome measures can be recommended use in clinical practice, for adults with musculoskeletal conditions of the knee, consensus should be obtained on 'feasibility' in terms of burden on the clinician and the participant.

The reliability of the quantitative timed up and go test (QTUG) measured over five consecutive days under single and dual-task conditions in community dwelling older adults.

Science.gov (United States)

Smith, Erin; Walsh, Lorcan; Doyle, Julie; Greene, Barry; Blake, Catherine

2016-01-01

The timed up and go (TUG) test is a commonly used assessment in older people with variations including the addition of a motor or cognitive dual-task, however in high functioning older adults it is more difficult to assess change. The quantified TUG (QTUG) uses inertial sensors to detect test and gait parameters during the test. If it is to be used in the longitudinal assessment of older adults, it is important that we know which parameters are reliable and under which conditions. This study aims to examine the relative reliability of the QTUG over five consecutive days under single, motor and cognitive dual-task conditions. Twelve community dwelling older adults (10 females, mean age 74.17 (3.88)) performed the QTUG under three conditions for five consecutive days. The relative reliability of each of the gait parameters was assessed using intra-class correlation coefficient (ICC 3,1) and standard error of measurement (SEM). Five of the measures demonstrated excellent reliability (ICC>0.70) under all three conditions (time to complete test, walk time, number of gait cycles, number of steps and return from turn time). Measures of variability and turn derived parameters demonstrated weak reliability under all three conditions (ICC=0.05-0.49). For the most reliable parameters under single-task conditions, the addition of a cognitive task resulted in a reduction in reliability suggesting caution when interpreting results under these conditions. Certain sensor derived parameters during the QTUG test may provide an additional resource in the longitudinal assessment of older people and earlier identification of falls risk.

Tsung-Hsun Lu; Yi-Chi Chen; Yu-Chin Hsu

2014-01-01

We ask what determines the profitability of candlestick patterns. Is it the definition of trend and/or the holding strategy that one uses in candlestick charting analysis? To answer this, we conduct a systematic investigation by considering three definitions of trend and four holding strategies. Based on the DJIA components data, we find that eight three-day reversal patterns with a Caginalp-Laurent holding strategy are profitable after we account for data-snooping bias. We also find that our...

Analysis of an inventory model for both linearly decreasing demand and holding cost

Science.gov (United States)

Malik, A. K.; Singh, Parth Raj; Tomar, Ajay; Kumar, Satish; Yadav, S. K.

2016-03-01

This study proposes the analysis of an inventory model for linearly decreasing demand and holding cost for non-instantaneous deteriorating items. The inventory model focuses on commodities having linearly decreasing demand without shortages. The holding cost doesn't remain uniform with time due to any form of variation in the time value of money. Here we consider that the holding cost decreases with respect to time. The optimal time interval for the total profit and the optimal order quantity are determined. The developed inventory model is pointed up through a numerical example. It also includes the sensitivity analysis.

Yoga Therapy: Building a Holding Environment for Somatic and Psyche Change.

Science.gov (United States)

McClure, Bud

2015-01-01

Drawing on ideas from D.W. Winnicott and the work of Quaker theologian Parker Palmer, this article discusses the concept of a holding environment, its refined understanding in the literature over the years, and how it can be optimally used in yoga therapy. The evidence shows that effectively establishing a holding environment can facilitate both somatic and deep structural change in a client, facilitating healing from primal wounding as well as the potential reconnection to the true self.

Collaborative remembering in older adults: age-invariant outcomes in the context of episodic recall deficits.

Science.gov (United States)

Henkel, Linda A; Rajaram, Suparna

2011-09-01

Rapidly growing research reveals complex yet systematic consequences of collaboration on memory in young adults, but much less is known about this phenomenon in older adults. Young and older adults studied a list of categorized words and took three successive recall tests. Test 1 and 3 were always taken individually, and Test 2 was done either in triads or alone. Despite older adults recalling less overall than young adults, both age groups exhibited similar costs and benefits of collaboration: Collaboration reduced both correct and false recall during collaborative remembering, was associated with more positive beliefs about its value, and produced reminiscence, collective memory, and some forgetting in its cascading effects on postcollaborative recall. We examine the role of retrieval organization in these effects. As environmental support may play a substantial role in healthy aging, the relatively preserved effects of collaboration on memory in older adults hold promise for testing judicious uses of group remembering in aging.

Holding Pressure and Its Influence on Quality in PIM Technology

Directory of Open Access Journals (Sweden)

Pavel Petera

2012-01-01

Full Text Available The PIM (powder injection molding process consists of several steps in which faults can occur. The quality of the part that is produced usually cannot be seen until the end of the process. It is therefore necessary to find a way to discover the fault earlier in the process. The cause of defects is very often “phase separation” (inhomogeneity in powder distribution, which can also be influenced by the holding pressure. This paper evaluates the powder distribution with a new method based on density measurement. Measurements were made using various holding pressure values.

Full Text Available Aim: The aims of present study were to compare the propofol and rocuronium with thiopentone and rocuronium in terms of clinically satisfactory intubating conditions and to co-relate intubating conditions with degree of paralysis in adductor pollicis muscle using train of four ratio (TOFR. The intubating conditions were evaluated after rocuronium bromide 0.6 mg kg−1 at 60 s. Materials and Methods : 60 patients of ASA grades I-II of either sex, age 18-50 years, undergoing various elective surgical procedures were randomly divided into two groups, propofol rocuronium (PR group and thiopentone rocuronium (TR group of 30 patients in each. In the PR group, patients received propofol 2.5 mg kg−1 and rocuronium 0.6 mg kg−1 ; in TR group, patients received thiopentone 5 mg kg−1 and rocuronium 0.6 mg kg−1 . In all patients the intubating conditions were evaluated by the observer at 60 s. TOFR was measured at the time of intubation by an assistant. Results : In the PR group the number of the patients placed in intubating conditions grades I, II, III and IV were 40%, 36.67%, 13.33% and 10% and their mean TOFR were 31.8±17.9%, 61.8±;14.6%, 61.7±27.9%, and 78.3±5.7% respectively. While in theTR group the number of patients placed in intubating condition grade I, II, and III were 60%, 26.67%, and 13.33% and their mean TOFR , 41.2±28.3%, 68.0±10.9% and 78.7±6.8%, respectively. There was no patient in grade lV in theTR group. Conclusion : The clinical intubating conditions and degree of paralysis of adductor pollicis muscle after rocuronium 0.6 mg kg−1 at 60 s in adults induced with propofol or thiopentone sodium are comparable.

Accurate step-hold tracking of smoothly varying periodic and aperiodic probability.

Science.gov (United States)

Ricci, Matthew; Gallistel, Randy

2017-07-01

Subjects observing many samples from a Bernoulli distribution are able to perceive an estimate of the generating parameter. A question of fundamental importance is how the current percept-what we think the probability now is-depends on the sequence of observed samples. Answers to this question are strongly constrained by the manner in which the current percept changes in response to changes in the hidden parameter. Subjects do not update their percept trial-by-trial when the hidden probability undergoes unpredictable and unsignaled step changes; instead, they update it only intermittently in a step-hold pattern. It could be that the step-hold pattern is not essential to the perception of probability and is only an artifact of step changes in the hidden parameter. However, we now report that the step-hold pattern obtains even when the parameter varies slowly and smoothly. It obtains even when the smooth variation is periodic (sinusoidal) and perceived as such. We elaborate on a previously published theory that accounts for: (i) the quantitative properties of the step-hold update pattern; (ii) subjects' quick and accurate reporting of changes; (iii) subjects' second thoughts about previously reported changes; (iv) subjects' detection of higher-order structure in patterns of change. We also call attention to the challenges these results pose for trial-by-trial updating theories.

Body Growth and Rapid Hematological Development Support Breath Hold of Baby Belugas (Delphinapterus leucas) during Subice Transit.

Science.gov (United States)

Noren, Shawn R; Poll, Caryn P; Edwards, Matthew S

Body size and oxygen stores in the blood and muscle set breath-hold limits in marine mammals, yet these characteristics are understudied in immature cetaceans. We examined body mass and hematology from birth through adulthood in beluga whales (Delphinapterus leucas). At birth, body mass was 8% and 6% of the maximum mass recorded for adult females and males, respectively. Body mass then increased rapidly, approaching an asymptote around 12 yr for females and 18 yr for males. Interestingly, red blood cell counts, hemoglobin content, and hematocrit levels decreased after birth; this neonatal anemia was reversed as levels increased after 2 mo postpartum. Mature levels were obtained at approximately 8, 9, and 11 mo postpartum, respectively. Neonatal mean corpuscular hemoglobin also increased with ontogeny; mature levels were achieved by approximately 13 mo after birth. In contrast, mean corpuscular volume and mean corpuscular hemoglobin concentration demonstrated a significant but subtle increase throughout ontogeny. Our results indicate that postnatal maturation was required and that maturation occurred far earlier than the age at weaning (i.e., 2-3 yr postpartum). This is atypical of marine mammals, which generally achieve mature hemoglobin levels at weaning. Hematological maturation before maternal independence undoubtedly supports the prolonged breath holds of young belugas transiting under sea ice. This assessment enhances our knowledge of cetacean physiology and provides important inputs for determining age-specific dive capacity, yielding insights into age-specific flexibility to alter underwater behaviors, as will be required for future regime shifts and disturbances.

Keegan, Theresa H M; Li, Qian; Steele, Amy; Alvarez, Elysia M; Brunson, Ann; Flowers, Christopher R; Glaser, Sally L; Wun, Ted

2018-06-01

Hodgkin lymphoma (HL) survivors experience high risks of second cancers and cardiovascular disease, but no studies have considered whether the occurrence of these and other medical conditions differ by sociodemographic factors in adolescent and young adult (AYA) survivors. Data for 5,085 patients aged 15-39 when diagnosed with HL during 1996-2012 and surviving ≥ 2 years were obtained from the California Cancer Registry and linked to hospitalization data. We examined the impact of race/ethnicity, neighborhood socioeconomic status (SES), and health insurance on the occurrence of medical conditions (≥ 2 years after diagnosis) and the impact of medical conditions on survival using multivariable Cox proportional hazards regression. Twenty-six percent of AYAs experienced at least one medical condition and 15% had ≥ 2 medical conditions after treatment for HL. In multivariable analyses, Black HL survivors had a higher likelihood (vs. non-Hispanic Whites) of endocrine [hazard ratio (HR) = 1.37, 95% confidence interval (CI) 1.05-1.78] and circulatory system diseases (HR = 1.58, CI 1.17-2.14); Hispanics had a higher likelihood of endocrine diseases [HR = 1.24 (1.04-1.48)]. AYAs with public or no insurance (vs. private/military) had higher likelihood of circulatory system diseases, respiratory system diseases, chronic kidney disease/renal failure, liver disease, and endocrine diseases. AYAs residing in low SES neighborhoods (vs. high) had higher likelihood of respiratory system and endocrine diseases. AYAs with these medical conditions or second cancers had an over twofold increased risk of death. Strategies to improve health care utilization for surveillance and secondary prevention among AYA HL survivors at increased risk of medical conditions may improve outcomes.

Hippocampal-dependent Pavlovian conditioning in adult rats exposed to binge-like doses of ethanol as neonates.

Science.gov (United States)

Lindquist, Derick H

2013-04-01

Binge-like postnatal ethanol exposure produces significant damage throughout the brain in rats, including the cerebellum and hippocampus. In the current study, cue- and context-mediated Pavlovian conditioning were assessed in adult rats exposed to moderately low (3E; 3g/kg/day) or high (5E; 5g/kg/day) doses of ethanol across postnatal days 4-9. Ethanol-exposed and control groups were presented with 8 sessions of trace eyeblink conditioning followed by another 8 sessions of delay eyeblink conditioning, with an altered context presented over the last two sessions. Both forms of conditioning rely on the brainstem and cerebellum, while the more difficult trace conditioning also requires the hippocampus. The hippocampus is also needed to gate or modulate expression of the eyeblink conditioned response (CR) based on contextual cues. Results indicate that the ethanol-exposed rats were not significantly impaired in trace EBC relative to control subjects. In terms of CR topography, peak amplitude was significantly reduced by both doses of alcohol, whereas onset latency but not peak latency was significantly lengthened in the 5E rats across the latter half of delay EBC in the original training context. Neither dosage resulted in significant impairment in the contextual gating of the behavioral response, as revealed by similar decreases in CR production across all four treatment groups following introduction of the novel context. Results suggest ethanol-induced brainstem-cerebellar damage can account for the present results, independent of the putative disruption in hippocampal development and function proposed to occur following postnatal ethanol exposure.

Mesenteric vasculitis in adults with Henoch-Schonlein purpura: a not-so-benign condition.

LENUS (Irish Health Repository)

Sibartie, V

2009-02-07

INTRODUCTION: The gastrointestinal manifestations of Henoch-Schonlein purpura (HSP) are well characterised, but their recognition can be difficult when they occur in isolation. Furthermore, HSP can run a more serious course in adults, compared to children, in whom the disease usually occurs. MATERIALS AND METHODS: We describe two cases that illustrate the challenges of HSP with mesenteric vasculitis and the outcome in adults. CONCLUSION: Although self-limiting in most patients, the outcome of HSP in adults can be far from benign and even fatal.

Dream Skepticism and the Conditionality Problem

DEFF Research Database (Denmark)

Ahlström, Kristoffer

2011-01-01

Recently, Ernest Sosa (2007) has proposed two novel solutions to the problem of dream skepticism. In the present paper, I argue that Sosa's first solution falls prey to what I will refer to as the conditionality problem, i.e., the problem of only establishing a conditional---in this case, "if x......, then I am awake," x being a placeholder for a condition incompatible with dreaming---in a context where it also needs to be established that we can know that the antecedent holds, and as such can infer the consequent, i.e., "I am awake." Sosa's second solution in terms of so-called reflective knowledge......, I conclude that Sosa has not solved the problem of dream skepticism....

Magnetic Resonance Imaging in Breath-Hold Divers with Cerebral Decompression Sickness

Directory of Open Access Journals (Sweden)

Ryu Matsuo

2014-01-01

Full Text Available The mechanism of cerebral decompression sickness (DCS is still unclear. We report 2 cases of breath-hold divers with cerebral DCS in whom magnetic resonance imaging (MRI demonstrated distinctive characteristics. One case presented right hemiparesthesia, diplopia, and gait disturbance after breath-hold diving into the sea at a depth of 20 m. Brain MRI with fluid-attenuated inversion recovery (FLAIR sequence revealed multiple hyperintense lesions in the right frontal lobe, bilateral thalamus, pons, and right cerebellar hemisphere. The second case presented visual and gait disturbance after repetitive breath-hold diving into the sea. FLAIR imaging showed hyperintense areas in the bilateral occipito-parietal lobes. In both cases, diffusion-weighted imaging and apparent diffusion coefficient mapping revealed hyperintense areas in the lesions identified by FLAIR. Moreover, follow-up MRI showed attenuation of the FLAIR signal abnormalities. These findings are suggestive of transient hyperpermeability in the microvasculature as a possible cause of cerebral DCS.

Full Text Available Background: Population-based data about utilization of complementary and alternative medicine (CAM among those with chronic conditions is lacking.Objective: To describe whether CAM use by California adults with cancer and other chronic conditions reflects condition specific patterns or a general tendency to use CAM modalities.Methods: Interviews of 9,187 respondents including all participants with cancer from a prior representative survey of California households, and a stratified sample of all other respondents. Almost 74% of the respondents reported at least one chronic health problem.Results: Use of all forms of CAM among those with chronic health problems is high. Those with a diagnosis of cancer are more likely to use prayer, dietary supplements, and support groups, and less likely to use CAM providers and special diets. Overall, individuals diagnosed with most chronic problems use a similar set of CAM modalities. Demographic correlates of CAM use differ in their impact and vary according to what type of CAM is being used.Conclusions: Clinicians should be aware that while a diagnosis of cancer is associated with a greater use of some forms of CAM, overall patterns of CAM use are similar to those with most other chronic problems.

Interfacial shear stress and hold-up in an air-water annular two-phase flow

International Nuclear Information System (INIS)

Fukano, T.; Ousaka, A.; Kawakami, Y.; Tominaga, A.

1991-01-01

This paper reports on an experimental investigation that was made into hold-up, frictional pressure drop and interfacial shear stress of an air-water two-phase annular flow in horizontal and vertical up- and downward flows to make clear the effects of tube diameter and flow direction on them. The tube diameters examined are 10mm, 16mm and 26mm. Both the hold-up and the pressure drop considerably changed with time. Especially, the amplitude of the variation of the hold-up was quite larger in comparison with its averaged value in the cause of disturbance wave flow. for the time averaged hold-up and interfacial friction factor, we got new correlations, by which we can estimate them within an accuracy of ±20% and ±30%, respectively, independent of the flow direction and the tube diameter

Effects of the active hold-off technique in 1.55-μm single-photon detection

International Nuclear Information System (INIS)

Bouzid, Abdessattar; Park, Junbum; Moon, Sung

2010-01-01

We investigate the effects of the active hold-off technique in single-photon detector (SPD) based on InGaAs/InP avalanche photodiodes (APDs). The concept of this technique is to hold-off an appropriate number of gate pulses after each recorded detection in order to wait for the trapping levels to empty. We found that at almost a 1-MHz repetition rate of the gate, such a hold-off mechanism must block at least two gate pulses after each photon click event to reduce the after-pulsing effect and does not significantly affect the count probability per gate. For higher repetition frequencies, the number of hold-off gates must be increased.

Paper presents the results of study on water retention by homogenous beef in gravitation field of 1500 g and water holding capacity in meat under influence of external force 20 N and osmotic forces. Significant changes in meat properties connected with water holding capacity along the first 3 days after slaughter were observed. These changes were generated by meat treatment with ultrasonic field just after slaughter

A Life Course Approach to Inequality: Examining Racial/Ethnic Differences in the Relationship between Early Life Socioeconomic Conditions and Adult Health Among Men.

Hargrove, Taylor W; Brown, Tyson H

2015-08-07

Previous research has documented a relationship between childhood socioeconomic conditions and adult health, but less is known about racial/ethnic differences in this relationship, particularly among men. This study utilizes a life course approach to investigate racial/ethnic differences in the relationships among early and later life socioeconomic circumstances and health in adulthood among men. Panel data from the Health and Retirement Study and growth curve models are used to examine group differences in the relationships among childhood and adult socioeconomic factors and age-trajectories of self-rated health among White, Black and Mexican American men aged 51-77 years (N=4147). Multiple measures of childhood socioeconomic status (SES) predict health in adulthood for White men, while significantly fewer measures of childhood SES predict health for Black and Mexican American men. Moreover, the health consequences of childhood SES diminish with age for Black and Mexican American men. The childhood SES-adult health relationship is largely explained by measures of adult SES for White men. The life course pathways linking childhood SES and adult health differ by race/ethnicity among men. Similar to arguments that the universality of the adult SES-health relationship should not be assumed, results from our study suggest that scholars should not assume that the significance and nature of the association between childhood SES and health in adulthood is similar across race/ethnicity among men.

On the duality condition for quantum fields

International Nuclear Information System (INIS)

Bisognano, J.J.; Wichmann, E.H.

1976-01-01

A general quantum field theory is considered in which the fields are assumed to be operator-valued tempered distributions. The system of fields may include any number of boson fields and fermion fields. A theorem which relates certain complex Lorentz transformations to the TCP transformation is stated and proved. With reference to this theorem, duality conditions are considered, and it is shown that such conditions hold under various physically reasonable assumptions about the fields. Extensions of the algebras of field operators are discussed with reference to the duality conditions. Local internal symmetries are discussed, and it is shown that these commute with the Poincare group and with the TCP transformation

Concurrent choice for social interaction and amphetamine using conditioned place preference in rats: effects of age and housing condition.

Science.gov (United States)

Yates, Justin R; Beckmann, Joshua S; Meyer, Andrew C; Bardo, Michael T

2013-05-01

Social interaction can serve as a natural reward that attenuates drug reward in rats; however, it is unknown if age or housing conditions alter the choice between social interaction and drug. Individually- and pair-housed adolescent and adult male rats were tested using conditioned place preference (CPP) in separate experiments in which: (1) social interaction was conditioned against no social interaction; (2) amphetamine (AMPH; 1mg/kg, s.c.) was conditioned against saline; or (3) social interaction was conditioned against AMPH. Social interaction CPP was obtained only in individually-housed adolescents, whereas AMPH CPP was obtained in both individually-housed adolescents and adults; however, the effect of AMPH was not statistically significant in pair-housed adults. When allowed to choose concurrently between compartments paired with either social interaction or AMPH, individually-housed adolescents preferred the compartment paired with social interaction, whereas pair-housed adolescents preferred the compartment paired with AMPH. Regardless of housing condition, adults showed a similar preference for the compartments paired with either social interaction or AMPH. Although some caution is needed in interpreting cross-experiment comparisons, the overall results suggest that individually-housed adolescents were most sensitive to the rewarding effect of social interaction, and this hypersensitivity to social reward effectively competed with AMPH reward.

Alibis for Adult Play: A Goffmanian Account of Escaping Embarrassment in Adult Play.

Science.gov (United States)

Deterding, Sebastian

2018-05-01

The social meanings of play sit at odds with norms of responsible and productive adult conduct. To be "caught" playing as an adult therefore risks embarrassment. Still, many designers want to create enjoyable, nonembarrassing play experiences for adults. To address this need, this article reads instances of spontaneous adult play through the lens of Erving Goffman's theory of the interaction order to unpack conditions and strategies for nonembarrassing adult play. It identifies established frames, segregated audiences, scripts supporting smooth performance, managing audience awareness, role distancing, and, particularly, alibis for play: Adults routinely provide alternative, adult-appropriate motives to account for their play, such as child care, professional duties, creative expression, or health. Once legitimized, the norms and rules of play themselves then provide an alibi for behavior that would risk being embarrassing outside play.

Increases in the numerical density of GAT-1 positive puncta in the barrel cortex of adult mice after fear conditioning.

Full Text Available Three days of fear conditioning that combines tactile stimulation of a row of facial vibrissae (conditioned stimulus, CS with a tail shock (unconditioned stimulus, UCS expands the representation of "trained" vibrissae, which can be demonstrated by labeling with 2-deoxyglucose in layer IV of the barrel cortex. We have also shown that functional reorganization of the primary somatosensory cortex (S1 increases GABAergic markers in the hollows of "trained" barrels of the adult mouse. This study investigated how whisker-shock conditioning (CS+UCS affected the expression of puncta of a high-affinity GABA plasma membrane transporter GAT-1 in the barrel cortex of mice 24 h after associative learning paradigm. We found that whisker-shock conditioning (CS+UCS led to increase expression of neuronal and astroglial GAT-1 puncta in the "trained" row compared to controls: Pseudoconditioned, CS-only, UCS-only and Naïve animals. These findings suggest that fear conditioning specifically induces activation of systems regulating cellular levels of the inhibitory neurotransmitter GABA.

Time discretization of the point kinetic equations using matrix exponential method and First-Order Hold

International Nuclear Information System (INIS)

Park, Yujin; Kazantzis, Nikolaos; Parlos, Alexander G.; Chong, Kil To

2013-01-01

Highlights: • Numerical solution for stiff differential equations using matrix exponential method. • The approximation is based on First Order Hold assumption. • Various input examples applied to the point kinetics equations. • The method shows superior useful and effective activity. - Abstract: A system of nonlinear differential equations is derived to model the dynamics of neutron density and the delayed neutron precursors within a point kinetics equation modeling framework for a nuclear reactor. The point kinetic equations are mathematically characterized as stiff, occasionally nonlinear, ordinary differential equations, posing significant challenges when numerical solutions are sought and traditionally resulting in the need for smaller time step intervals within various computational schemes. In light of the above realization, the present paper proposes a new discretization method inspired by system-theoretic notions and technically based on a combination of the matrix exponential method (MEM) and the First-Order Hold (FOH) assumption. Under the proposed time discretization structure, the sampled-data representation of the nonlinear point kinetic system of equations is derived. The performance of the proposed time discretization procedure is evaluated using several case studies with sinusoidal reactivity profiles and multiple input examples (reactivity and neutron source function). It is shown, that by applying the proposed method under a First-Order Hold for the neutron density and the precursor concentrations at each time step interval, the stiffness problem associated with the point kinetic equations can be adequately addressed and resolved. Finally, as evidenced by the aforementioned detailed simulation studies, the proposed method retains its validity and accuracy for a wide range of reactor operating conditions, including large sampling periods dictated by physical and/or technical limitations associated with the current state of sensor and

A low-power, CMOS peak detect and hold circuit for nuclear pulse spectroscopy

Ericson, M.N.; Simpson, M.L.; Britton, C.L.; Allen, M.D.; Kroeger, R.A.; Inderhees, S.E.

1994-01-01

A low-power CMOS peak detecting track and hold circuit optimized for nuclear pulse spectroscopy is presented. The circuit topology eliminates the need for a rectifying diode, reducing the effect of charge injection into the hold capacitor, incorporates a linear gate at the input to prevent pulse pileup, and uses dynamic bias control that minimizes both pedestal and droop. Both positive-going and negative-going pulses are accommodated using a complementary set of track and hold circuits. Full characterization of the design fabricated in 1.2μm CMOS including dynamic range, integral nonlinearity, droop rate, pedestal, and power measurements is presented. Additionally, analysis and design approaches for optimization of operational characteristics are discussed

Effect of ohmic heating of soymilk on urease inactivation and kinetic analysis in holding time.

Li, Fa-De; Chen, Chen; Ren, Jie; Wang, Ranran; Wu, Peng

2015-02-01

To verify the effect of the ohmic heating on the urease activity in the soymilk, the ohmic heating methods with the different electrical field conditions (the frequency and the voltage ranging from 50 to 10 kHz and from 160 to 220 V, respectively) were employed. The results showed that if the value of the urease activity measured with the quantitative spectrophotometry method was lower than 16.8 IU, the urease activity measured with the qualitative method was negative. The urease activity of the sample ohmically heated was significantly lower than that of the sample conventionally heated (P urease inactivation. In addition, the inactivation kinetics of the urease in the soymilk could be described with a biphasic model during holding time at a target temperature. Thus, it was concluded that the urease in the soymilk would contain 2 isoenzymes, one is the thermolabile fraction, the other the thermostable fraction, and that the thermostable isoenzyme could not be completely inactivated when the holding time increased, whether the soymilk was cooked with the conventional method or with the ohmic heating method. Therefore, the electric field had no effect on the inactivation of the thermostable isoenzyme of the urease. © 2015 Institute of Food Technologists®

Effect of visual cues on the resolution of perceptual ambiguity in Parkinson's disease and normal aging.

Science.gov (United States)

Díaz-Santos, Mirella; Cao, Bo; Mauro, Samantha A; Yazdanbakhsh, Arash; Neargarder, Sandy; Cronin-Golomb, Alice

2015-02-01

Parkinson's disease (PD) and normal aging have been associated with changes in visual perception, including reliance on external cues to guide behavior. This raises the question of the extent to which these groups use visual cues when disambiguating information. Twenty-seven individuals with PD, 23 normal control adults (NC), and 20 younger adults (YA) were presented a Necker cube in which one face was highlighted by thickening the lines defining the face. The hypothesis was that the visual cues would help PD and NC to exert better control over bistable perception. There were three conditions, including passive viewing and two volitional-control conditions (hold one percept in front; and switch: speed up the alternation between the two). In the Hold condition, the cue was either consistent or inconsistent with task instructions. Mean dominance durations (time spent on each percept) under passive viewing were comparable in PD and NC, and shorter in YA. PD and YA increased dominance durations in the Hold cue-consistent condition relative to NC, meaning that appropriate cues helped PD but not NC hold one perceptual interpretation. By contrast, in the Switch condition, NC and YA decreased dominance durations relative to PD, meaning that the use of cues helped NC but not PD in expediting the switch between percepts. Provision of low-level cues has effects on volitional control in PD that are different from in normal aging, and only under task-specific conditions does the use of such cues facilitate the resolution of perceptual ambiguity.

Importance of lunar and temporal conditions for spotlight surveys of adult black-footed ferrets

Science.gov (United States)

Eads, David A.; Jachowski, David S.; Millspaugh, Joshua J.; Biggins, Dean E.

2012-01-01

Black-footed ferrets (Mustela nigripes) spend most daylight hours underground in prairie dog (Cynomys) burrows and exhibit aboveground movements primarily at night. Moonlight can influence the activity patterns of ferrets and, consequently, might influence the efficiency of spotlight surveys used by biologists to monitor ferret populations. We related detection of adult ferrets during postbreeding spotlight surveys to lunar and temporal conditions. We most frequently located ferrets during surveys in which the moon breached the horizon. The data suggested intersexual differences in response to moonlight. We located male ferrets most frequently during nights with greater moon illumination, but we did not detect a correlation between moon illumination and spotlight detection of female ferrets. In general, moonlight could facilitate aboveground navigation by ferrets. However, it seems activity under bright moonlight could be costly for female ferrets while they raise young. Detection of ferrets also varied among months. We detected female ferrets most frequently in August–September, when mothers increase hunting efforts to acquire prey for growing offspring (kits). Detection of adult female ferrets declined in October, when kits were likely independent of their mother. We located male ferrets most frequently in September–October, when males might increase activity to monitor female ferrets and male competitors. Consideration of lunar and temporal influences and standardization of postbreeding surveys could enhance site-specific assessment of reintroduction success and across-site assessment of species recoveiy progress. We suggest that postbreeding surveys for ferrets should be enhanced by concentrating efforts in August–September during moonlit nights when the moon is above the horizon.

Adolescents' and young adults' perception of homosexuality plays an important role in the marginalization and stigmatization of the homosexual, thereby influencing his or her health. This article aims to study that perception and to examine its predictors in three Asian cities that are culturally dominated by Confucianism. From May 2006 to January 2007, a cross-sectional survey of 17,016 adolescents and young adults, aged 15-24 years old, in both urban and rural sites of three Asian cities (Hanoi in Vietnam, Shanghai in the mainland of China, and Taipei in Taiwan) was conducted through interview and computer-assisted self-interview for sensitive questions. Chi-square tests and multivariate logistic regression were performed to identify the predictors for their perception of homosexuality. The percentage of adolescents and young adults who hold a positive view of homosexuality (i.e., thought it was normal and/or acceptable) was low, especially in Hanoi and Shanghai; these figures increased from Hanoi to Shanghai to Taipei for both males and females. Overall, those factors significantly associated with adolescents' and young adults' perception of homosexuality included individuals' demographic characteristics (urban/rural, age, economic status, student status, and educational level), preferred origin of movies/videos, self-identified sexual orientation, sexual and reproductive health knowledge, family values, gender role values, and attitudes toward premarital sex. In these three Asian cities composed of populations whose views are largely influenced by Confucianism, adolescents and young adults mainly hold a negative perception of homosexuality. The most common and important predictors for a respondent's perception of homosexuality were his or her knowledge of sexual and reproductive health and how traditional his/her values may be. Greater attention needs to be paid to the popularization of knowledge about sexual and reproductive health including homosexuality

Full Text Available The scientific paper evaluates the impact of innovative projects on the competitiveness of agricultural holdings in SR. Evaluation of the impact of innovative projects on competitiveness of agricultural holdings was realized on the selected holdings in Nitra and Trnava region. For the evaluation was used RCR coefficient. With the use of RCR coefficient could be confirmed the scientific hypothesis - The innovative projects realized through Program for rural development SR 2007-2013 have positive impact on competitiveness of agricultural holdings. The possibilities for EU financial support for innovative projects in SR represent important source for introduction of new innovative technologies into production process and in future they can significantly contribute to the growth of competitiveness of agricultural subjects. Therefore, to increase competitiveness of agricultural holdings it is important to focus on modernization of machinery and buildings, use of natural sources for energy production, but also to increase the education and the flow of information between rural inhabitants, mainly farmers. In competitive area of EU agricultural sector it is necessary that agricultural holdings will innovate, not only to create independent flow of innovative products and knowledge, but also to increase its value on internal market. Agricultural holdings –receivers of financial support – have expressed the opinion that financial support realized through PRD SR 2007-2013 had definitely allowed them to implement new processes and products.

Poker is a family of games that exhibit imperfect information, where players do not have full knowledge of past events. Whereas many perfect-information games have been solved (e.g., Connect Four and checkers), no nontrivial imperfect-information game played competitively by humans has previously been solved. Here, we announce that heads-up limit Texas hold'em is now essentially weakly solved. Furthermore, this computation formally proves the common wisdom that the dealer in the game holds a substantial advantage. This result was enabled by a new algorithm, CFR(+), which is capable of solving extensive-form games orders of magnitude larger than previously possible.

Full Text Available The role of cerebral blood flow (CBF on a maximal breath-hold (BH in ultra-elite divers was examined. Divers (n = 7 performed one control BH, and one BH following oral administration of the non-selective cyclooxygenase inhibitor indomethacin (1.2 mg/kg. Arterial blood gases and CBF were measured prior to (baseline, and at BH termination. Compared to control, indomethacin reduced baseline CBF and cerebral delivery of oxygen (CDO2 by about 26% (p < 0.01. Indomethacin reduced maximal BH time from 339 ± 51 to 319 ± 57 seconds (p = 0.04. In both conditions, the CDO2 remained unchanged from baseline to the termination of apnea. At BH termination, arterial oxygen tension was higher following oral administration of indomethacin compared to control (4.05 ± 0.45 vs. 3.44 ± 0.32 kPa. The absolute increase in CBF from baseline to the termination of apnea was lower with indomethacin (p = 0.01. These findings indicate that the impact of CBF on maximal BH time is likely attributable to its influence on cerebral H+ washout, and therefore central chemoreceptive drive to breathe, rather than to CDO2.

In cheese powder production, cheese is mixed and melted with water and emulsifying salt to form an emulsion (cheese feed) which is required to remain stable at 60°C for 1h and during further processing until spray drying. Addition of emulsifying salts ensures this, but recent demands for reduction...... of sodium and phosphate in foods makes production of cheese powder without or with minimal amounts of emulsifying salts desirable. The present work uses a centrifugation method to characterize stability of model cheese feeds. Stability of cheese feed with emulsifying salt increased with holding time at 60°C......, especially when no stirring was applied. No change in stability during holding was observed in cheese feeds without emulsifying salt. This effect is suggested to be due to continued exerted functionality of the emulsifying salt, possibly through reorganizations of the mineral balance....
