  15. The hoarding of possessions.

    Science.gov (United States)

    Frost, R O; Gross, R C

    1993-05-01

    Three studies of nonfood hoarding are reported. Findings support the reliability and validity of a Hoarding Scale. Furthermore, the findings indicate a number of features of hoarding behavior. Hoarding was associated with indecisiveness, perfectionism (especially maladaptive evaluative concern) and obsessive compulsive symptoms among college students and community volunteers. Hoarders tended to buy extra things in order not to be caught without a needed item, and they carried more 'just-in-case' items in purses, pockets and cars. Onset of hoarding was childhood and adolescence. Hoarders had more first degree relatives who engaged in excessive saving than nonhoarders, and hoarders were less likely to be married. There was no evidence to suggest that hoarding was related to material deprivation. A model was suggested which conceptualizes hoarding as an avoidance behavior tied to indecisiveness and perfectionism. Saving allows the hoarder to avoid the decision required to throw something away, and the worry which accompanies that decision (worry that a mistake has been made). Also, it allows hoarders to avoid emotional reactions which accompany parting with cherished possessions, and results in increased perception of control.

    2008-08-01

    Compulsive hoarding is a common and often disabling neuropsychiatric disorder. This article reviews the conceptualization, phenomenology, diagnosis, etiology, neurobiology, and treatment of compulsive hoarding. Compulsive hoarding is part of a discrete clinical syndrome that includes difficulty discarding, urges to save, excessive acquisition, indecisiveness, perfectionism, procrastination, disorganization, and avoidance. It was thought to be part of obsessive-compulsive disorder or obsessive-compulsive personality disorder, but recent evidence indicates that it should be classified as a separate disorder with its own diagnostic criteria. Compulsive hoarding is a genetically discrete, strongly heritable phenotype. Neuroimaging and neuropsychological studies are elucidating its neurobiology, implicating dysfunction of ventral and medial prefrontal cortical areas that mediate decision-making, attention, and emotional regulation. Effective treatments include pharmacotherapy and cognitive-behavioral therapy. More research will be required to determine the prevalence, etiology, and pathophysiology of compulsive hoarding and to develop better treatments.

    Hoarding is seen in several psychiatric conditions, but has not been specifically assessed in Parkinson's disease (PD). This study investigates hoarding tendency amongst patients with PD, and its association with impulsive-compulsive spectrum behaviors (ICBs). We compare clinical features, measures of hoarding, impulse buying, self-control, obsessive-compulsive symptoms, depression, and anxiety in 39 patients with PD with ICBs (PD + ICB), 61 patients with PD without ICBs (PD - ICB), and 50 healthy controls. A much higher proportion of PD + ICB (27.8%) than PD - ICB (3.5%) were hoarders (P = 0.001). 6% of healthy controls were hoarders. Compulsive shoppers scored higher than other varieties of ICB on excessive acquisition measures. Hoarding correlated positively with impulsive buying, obsessive-compulsive symptoms, PD duration, and negatively with self-control measures. Using multivariate regression analyzes, the presence of ICBs and measures of impulsive buying were the only variables independently associated with hoarding in PD. The association of hoarding with other ICBs and low trait impulse control suggests that excessive hoarding is related to the spectrum of impulsive behaviors in PD.

    Local bias within a country and between countries is well established in the empirical literature. However, the underlying reasons are less well established. In a simple supply and demand framework, Hong, Kubik and Stein (JFE 2008) find an “only-game-in-town” effect in the U.S. - the stock price...... in a region decreases in the ratio of aggregate book value of listed firms to the aggregate personal income (“RATIO”). We first replicate the HKS (2008) study using European data and find an opposite effect, a “game-hoarding” effect. We then investigate the underlying factors of RATIO and find that after...... controlling for differences in origin of law, investor rights, corruption and Euro adoption, neither a game-hoarding effect nor an only-game-in-town effect is strongly supported in the European case. The results are important in understanding the concept of local bias in a cross-country framework....

  10. Hoarding behaviors in a large college sample.

    Coles, Meredith E; Frost, Randy O; Heimberg, Richard G; Steketee, Gail

    2003-02-01

    Hoarding behaviors occur in many clinical syndromes but are most commonly linked to obsessive compulsive disorder. Surprisingly little empirical work has examined the nature of hoarding behaviors despite their association with significant distress and impairment. The current study examined hoarding in 563 unselected college students. Using principal components analysis, we identified four domains of hoarding behaviors as measured by the 26-item Saving Inventory-Revised: Difficulty Discarding, Acquisition Problems, Clutter, and Interference/Distress. All four domains and total hoarding behaviors were strongly related to hoarding beliefs and to obsessive compulsive (OC) symptoms. Hoarding behaviors were most strongly correlated with subscales of an OC disorder (OCD) measure assessing hoarding and obsessions and least strongly correlated with the washing subscale. Hoarding behaviors also showed significant, but more modest, correlations with social anxiety, depressive symptoms, and worry. However, worry was not found to contribute unique variance to the prediction of hoarding behaviors. Of greatest note, hoarding behaviors showed a surprisingly strong relationship with anxiety sensitivity, similar in magnitude to the relationship between hoarding and OCD symptoms. Results are interpreted and lines of future research are proposed, with particular emphasis on further elucidating the relationship between hoarding behaviors and anxiety sensitivity.

Compulsive hoarding is part of a discrete clinical syndrome that includes difficulty discarding, urges to save, clutter, excessive acquisition, indecisiveness, perfectionism, procrastination, disorganization, and avoidance. Epidemiological and taxometric studies indicate that compulsive hoarding is a separate but related obsessive-compulsive spectrum disorder that is frequently comorbid with obsessive-compulsive disorder (OCD). Compulsive hoarding is a genetically discrete, strongly heritable phenotype. Neuroimaging and neuropsychological studies indicate that compulsive hoarding is neurobiologically distinct from OCD and implicate dysfunction of the anterior cingulate cortex and other ventral and medial prefrontal cortical areas that mediate decision-making, attention, and emotional regulation. Effective treatments for compulsive hoarding include pharmacotherapy and cognitive-behavioral therapy. More research will be required to determine the etiology and pathophysiology of compulsive hoarding, and to develop better treatments for this disorder.

  18. The history of scatter hoarding studies.

    Science.gov (United States)

    Brodin, Anders

    2010-03-27

    In this review, I will present an overview of the development of the field of scatter hoarding studies. Scatter hoarding is a conspicuous behaviour and it has been observed by humans for a long time. Apart from an exceptional experimental study already published in 1720, it started with observational field studies of scatter hoarding birds in the 1940s. Driven by a general interest in birds, several ornithologists made large-scale studies of hoarding behaviour in species such as nutcrackers and boreal titmice. Scatter hoarding birds seem to remember caching locations accurately, and it was shown in the 1960s that successful retrieval is dependent on a specific part of the brain, the hippocampus. The study of scatter hoarding, spatial memory and the hippocampus has since then developed into a study system for evolutionary studies of spatial memory. In 1978, a game theoretical paper started the era of modern studies by establishing that a recovery advantage is necessary for individual hoarders for the evolution of a hoarding strategy. The same year, a combined theoretical and empirical study on scatter hoarding squirrels investigated how caches should be spaced out in order to minimize cache loss, a phenomenon sometimes called optimal cache density theory. Since then, the scatter hoarding paradigm has branched into a number of different fields: (i) theoretical and empirical studies of the evolution of hoarding, (ii) field studies with modern sampling methods, (iii) studies of the precise nature of the caching memory, (iv) a variety of studies of caching memory and its relationship to the hippocampus. Scatter hoarding has also been the subject of studies of (v) coevolution between scatter hoarding animals and the plants that are dispersed by these.

  19. Hoarding, compulsive buying and reasons for saving.

    Science.gov (United States)

    Frost, R O; Kim, H J; Morris, C; Bloss, C; Murray-Close, M; Steketee, G

    1998-01-01

    Two studies examined hypotheses about compulsive hoarding, compulsive buying and beliefs about saving and discarding derived from the cognitive-behavioral model of compulsive hoarding [Frost, R. O. and Hartl, T. (1996). A cognitive behavioral model of compulsive hoarding. Behaviour Research and Therapy, 34, 341-350.]. Study 1 examined the hypotheses in a college student population, while study 2 compared members of a support group for hoarding and clutter-related problems with a nonclinical control. Across studies the hypotheses were supported. Compulsive hoarding was associated with compulsive buying and the frequency of acquisition of possessions discarded by others, suggesting that compulsive acquisition may be a broader construct than compulsive buying among people with hoarding problems. Regarding its association with OCD symptoms, hoarding was most closely associated with the impaired mental control features of OCD. Finally, offa hoarding-related task, hoarding was associated with a greater frequency of reasons to save, but was not associated with fewer reasons to discard a target possession.

    Overconfidence is a well-established behavioral phenomenon that involves an overestimation of own capabilities. We introduce a model, in which managers and agents exert effort in a joint production, after the manager decides on the allocation of the tasks. A rational manager tends to delegate the critical task to the agent more often than given by the efficient task allocation. In contrast, an overconfident manager is more likely to hoard responsibility, i.e. to delegate the critical task les...

  9. Hoarding: a symptom, not a syndrome.

    Science.gov (United States)

    Damecour, C L; Charron, M

    1998-05-01

    Hoarding behavior in humans spans a continuum from normal collecting to pathological self-neglect and can be associated with a variety of psychiatric disorders. The authors summarize research in the past 15 years characterizing hoarding behavior in groups of college students, in nonclinical populations of self-named "pack rats," in outpatients treated for obsessive-compulsive disorder (OCD), and in individual pathological hoarders presented in psychiatric case reports. Two new case reports of pathological hoarding are presented here. The literature suggests, as do the 2 case reports presented, that certain factors may be common to all groups of hoarders, as they all show poor insight, lack of resistance to the compulsion to hoard, and poor treatment motivation. Possible biological and psychosocial determinants of pathological hoarding include association with schizophrenia, OCD, and tic disorders, as well as a possible link through the neurotransmitter dopamine. Management issues range from psychopharmacologic treatment with antipsychotic medication to behavioral therapy and environmental manipulation.

    The extant research on animal hoarding has a dearth of information on animal hoarding tendencies in adults diagnosed with hoarding disorder (HD). In the present study, we investigated possible recurrent animal hoarding behavioral and symptom patterns in individuals diagnosed with hoarding disorder. Hoarding severity scores from baseline assessments for 65 community-dwelling adults diagnosed with HD were analyzed with respect to their present and past animal ownership characteristics. Approximately half of participants reported currently owning pets, and pet owners in the sample reported currently owning an average of two pets. Of the participants who reported currently owning animals, 10% reported having no rules for their pets' behaviors, 51% reported having made at least one sacrifice for their pets, 54% reported having had at least one pet in childhood, and 29% reported that they believed they have a "special ability" to communicate with their pets. The results of the present study suggest that animal hoarding is not necessarily present in individuals diagnosed with HD. No significant associations of current pet ownership characteristics with present hoarding severity were observed. Reported maximum number of pets owned in childhood was significantly correlated with present object hoarding symptom severity. © 2016 Wiley Periodicals, Inc.

  9. Scatter-hoarding rodents prefer slightly astringent food.

    Directory of Open Access Journals (Sweden)

    Bo Wang

    Full Text Available The mutualistic interaction between scatter-hoarding rodents and their seed plants is highly complex yet poorly understood. Plants may benefit from the seed dispersal behavior of rodents, as long as seed consumption is minimized. In parallel, rodents may maximize foraging efficiency and cache high-quality resources for future consumption. Defensive compounds, such as tannins, are thought to be a major mechanism for plant control over rodent behavior. However, previous studies, using naturally occurring seeds, have not provided conclusive evidence supporting this hypothesis. Here, we test the importance of tannin concentrations on the scatter-hoarding behavior of rodents by using an artificial seed system. We combined feeding trials and field observations to examine the overall impact of seed tannin concentrations on rodent behavior and health. We found that rodents favored seeds with an intermediate amount of tannin (~5% in the field. Meanwhile, in rodents that were fed a diet with different tannin content, only diets with high tannin content (25%, 15%, and 10% caused a significant negative influence on rodent survival and health. Significant differences were not found among treatments with tannin levels of 0-5%. In contrast to many existing studies, our results clearly demonstrate that scatter-hoarding rodents prefer slightly 'astringent' food. In the co-evolutionary arms race between plants and animals, our results suggest that while tannins may play a significant role in reducing general predation levels by the faunal community, they have no precise control over the behavior of their mutualistic partner. Instead, the two partners appear to have reached an evolutionary point where both parties receive adequate benefits, with the year-to-year outcome being dependent on a wide range of factors beyond the control of either partner.

    Hoarding is common among youth with obsessive compulsive disorder (OCD), with up to 26% of OCD youth exhibiting hoarding symptoms. Recent evidence from adult hoarding and OCD cohorts suggests that hoarding symptoms are associated with executive functioning deficits similar to those observed in subjects with attention deficit hyperactivity disorder (ADHD). However, while hoarding behavior often onsets during childhood, there is little information about executive function deficits and ADHD in affected children and adolescents. The study sample included 431 youths (ages 6-17 years) diagnosed with OCD who participated in the OCD Collaborative Genetics Study and the OCD Collaborative Genetics Association Study and completed a series of clinician-administered and parent report assessments, including diagnostic interviews and measures of executive functioning (Behavior Rating Inventory of Executive Functioning; BRIEF) and hoarding severity (Hoarding Rating Scale-Interview; HRS-I). 113 youths (26%) had clinically significant levels of hoarding compulsions. Youths with and without hoarding differed significantly on most executive functioning subdomains and composite indices as measured by the parent-rated BRIEF. Groups did not differ in the frequency of full DSM-IV ADHD diagnoses; however, the hoarding group had significantly greater number of inattention and hyperactivity symptoms compared to the non-hoarding group. In multivariate models, we found that overall BRIEF scores were related to hoarding severity, adjusting for age, gender and ADHD symptoms. These findings suggest an association between hoarding and executive functioning deficits in youths with OCD, and assessing executive functioning may be important for investigating the etiology and treatment of children and adolescents with hoarding and OCD.

    Full Text Available Hoarding Disorder (HD was originally conceptualized as a subcategory of Obsessive Compulsive Disorder (OCD, and numerous studies have in fact focused exclusively on investigating the comorbidity between OCD and HD. Hoarding behavior can nevertheless also be found in other clinical populations and in particular in patients with eating disorders (ED, anxiety disorders (AD, major depression (MD, and psychotic disorders (PD. The current study was carried out with the aim of investigating, using a validated instrument such as the Saving Inventory-Revised (SI-R, the presence of HD symptoms in patients diagnosed with ED, AD, MD and PD. Hoarding symptomatology was also assessed in groups of self-identified hoarders (SIH and healthy controls. The results revealed that 22.5% of the ED patients exceeded the cut-off for the diagnosis of HD, followed by 7.7% of the patients with MD, 7.4% of the patients with AD, and 5.9% of the patients with PD. The patients with ED had significantly higher SI-R scores than the other groups in the Acquisition and Difficulty Discarding scales while the AD, MD, and PD patients were characterized exclusively by Difficulty Discarding. These data suggest to clinicians that hoarding symptoms should be assessed in other types of patients and especially in those affected by Bulimia and Binge eating.

  17. Social context modulates food hoarding in Syrian hamsters

    Directory of Open Access Journals (Sweden)

    Bibiana Montoya

    2016-09-01

    Full Text Available The effect of the presence of a con-specific in the temporal organization of food hoarding was studied in two varieties of Syrian hamster (Mesocricetus auratus: golden and long-haired. Four male hamsters of each variety were used. Their foraging behavior was observed during four individual and four shared trials in which animals were not competing for the same food source or territory. During individual trials, long-haired hamsters consumed food items directly from the food source, transporting and hoarding only remaining pieces. During shared trials, the long-haired variety hoarded food items before consumption, and increased the duration of hoarding trips, food handling in the storage, and cache size. Golden hamsters maintained the same temporal organization of hoarding behavior (i.e., hoarding food items before consumption throughout both individual and shared trials. However, the golden variety increased handling time at the food source and decreased the duration of hoarding trips, the latency of hoarding and storing size throughout the shared trials. In Syrian hamsters, the presence of a con-specific may signal high probability of food source depletion suggesting that social pressures over food availability might facilitate hoarding behavior. Further studies are required to evaluate cost-benefit balance of food hoarding and the role of cache pilferage in this species.

  18. Anxiety sensitivity: a potential vulnerability factor for compulsive hoarding.

    Science.gov (United States)

    Medley, Amanda N; Capron, Daniel W; Korte, Kristina J; Schmidt, Norman B

    2013-01-01

    Compulsive hoarding is defined as the accumulation of and failure to discard a large number of possessions that appear to be useless or limited in value. Severe hoarding can result in illnesses due to unsanitary conditions, social isolation, work disability, and even death. Despite the severity of impairment associated with this clinical syndrome, research examining potential vulnerability factors is limited. Two independent studies have demonstrated that hoarding behaviors are significantly associated with anxiety sensitivity (AS), a well-known risk factor for anxiety pathology. However, the relationship between AS subfactors and hoarding behaviors is somewhat unclear. The primary aim of this investigation was to examine the relationships between hoarding and AS subfactors utilizing the anxiety sensitivity index-3, a measure designed to more accurately assess AS subfactors. Participants consisted of 279 college students, as well as 210 non-selected clinical participants. Consistent with initial predictions, hoarding behaviors were significantly associated with overall AS. Moreover, when looking at the relationships among hoarding behaviors and specific AS subfactors, hoarding was significantly associated with the physical concerns subscale. Finally, when examining the relationships among overall AS and specific hoarding facets, results indicated that the difficulty discarding subfactor of hoarding was associated with overall AS. Implications for future research and treatment are discussed.

  19. Interpersonal trauma and hoarding: The mediating role of aggression.

    Mathes, Brittany M; Portero, Amberly K; Gibby, Brittany A; King, Savannah L; Raines, Amanda M; Schmidt, Norman B

    2017-11-14

    A growing body of literature indicates that exposure to interpersonal trauma contributes to the onset or exacerbation of hoarding symptoms. However, little research has explored psychosocial factors that may help to explain the relationship between interpersonal trauma and hoarding symptoms. One outcome of trauma exposure that may be associated with hoarding symptoms is aggression, defined as the tendency to experience and express hostility and anger, and to engage in aggressive behavior. Therefore, the current study examined the relationship between hoarding and aggression, as well as the mediating role of aggression in the relationship between exposure to interpersonal trauma and hoarding symptoms. Community participants (n = 258) completed a battery of questionnaires assessing trauma exposure, hoarding symptoms, aggression, and negative affect. Results revealed that when accounting for negative affect, hoarding symptoms were associated with greater aggression, and the relationship between exposure to interpersonal trauma and hoarding symptoms was mediated by aggression. Specificity analyses indicated that depression symptoms and emotion dysregulation did not mediate the relationship between interpersonal trauma exposure and hoarding, providing further support for the importance of aggression. Findings should be interpreted in light of limitations, including the use of cross-sectional and self-report data, and a general community sample. Taken together, our findings suggest that interpersonal processes, such as aggression toward others, may be associated with increased hoarding symptoms. Copyright © 2017 Elsevier B.V.

  20. Hoarding in a compulsive buying sample.

    Mueller, Astrid; Mueller, Ulrike; Albert, Patricia; Mertens, Christian; Silbermann, Andrea; Mitchell, James E; de Zwaan, Martina

    2007-11-01

    Previous research has indicated that many compulsive buyers also suffer from compulsive hoarding. The present work specifically examined hoarding in a compulsive buying sample. Sixty-six treatment-seeking compulsive buyers were assessed prior to entering a group therapy for compulsive buying using the Compulsive Buying Scale (CBS), the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS)-Shopping Version, the Compulsive Acquisition Scale (CAS), the German-CBS, the Saving Inventory-Revised (SI-R), the Maudsley Obsessive Compulsive Inventory (MOCI), the Barratt Impulsiveness Scale (BIS-11), and the Structured Clinical Interview for DSM-IV Axis I (SCID). Inclusion criteria were current problems with compulsive buying according to the proposed diagnostic criteria for compulsive buying by McElroy, Keck, Pope, Smith, and Strakowski [(1994). Compulsive buying: A report of 20 cases. Journal of Clinical Psychiatry, 55, 242-248]. Our results support the assumption that many but not all compulsive buyers suffer from compulsive hoarding. A significant association between the SI-R and the compulsive buying measures CBS, Y-BOCS-SV, German-CBS, and the CAS-Buy subscale was found, which is mostly caused by the SI-R subscale acquisition. The SI-R subscales clutter and difficulty discarding were more closely associated with the CAS-Free subscale and with obsessive-compulsive symptoms. Hoarding compulsive buyers reported more severe buying symptoms and obsessive-compulsive symptoms and presented with a higher psychiatric co-morbidity, especially any current affective, anxiety and eating disorder. Specific therapeutic interventions for compulsive buyers who also report compulsive hoarding appear indicated.

    This qualitative study examined multidisciplinary team members' perspectives of their involvement in older adult hoarding cases. Fifteen informants, as representatives of four hoarding teams, described cases in which teams did or did not work well together. Specifically, informants described their (a) team characteristics, (b) awareness of hoarding as a mental health illness, (c) barriers to providing mental health services for older adults who hoard, and (d) components of successful teamwork within the team and with the older adult as hoarder. Implications include research to better guide interventions, team training to develop common perspectives, and policy development that supports mental health representation on teams and in-home mental health treatment.

  2. Trash and Aesthetics in the Hoard

    Directory of Open Access Journals (Sweden)

    Charmaine Eddy

    2015-06-01

    Full Text Available Trash and Aesthetics in the Hoard by Charmaine Eddy, Issue 7: The Aesthetics of Trash. This article examines two reality television series, Hoarders and Hoarding: Buried Alive, in terms of a variation in the understanding of the object in relation to value based upon an aesthetic tied to consumer capitalism. Object collection is viewed as a spectacle of abjection in each episode, as items that were once worthy of purchase come to produce a garbage heap within the home. The concept of “trash” is an evaluative category applied to objects over time, but it also becomes part of the therapeutic process, as hoarders are required to dispose of their things. Object-oriented ontology, or “thing theory,” provides an alternate semiology for the object, ultimately illustrating how an evaluative aesthetics of the object in these series is linked to consumer capitalism and normative patterns of consumption.

    Acquiring and discarding objects are routine decision processes for most people. Despite the ubiquitous need to make such decisions, little is known about how they are made and what goes wrong when individuals acquire and fail to discard so many items that many areas of their home become unlivable (i.e., clinical hoarding). We hypothesize that clinical hoarding reflects a normal variation in the tendency to acquire and retain objects, only just at a more extreme level. To test this hypothesis, we examined 89 nonclinical, undergraduate students' performance on a novel experimental paradigm that measures decisions about acquiring and discarding everyday objects. To test our hypothesis, and validate our task as a possible research tool for studying hoarding, we related decisions on the task to a variety of measures known to correlate with clinical hoarding. The paradigm was sensitive to individual differences, as subjects varied widely in the quantity of objects they chose to acquire and retain under an increasing pressure to discard. In addition, we replicated expected relationships from the clinical hoarding literature between acquisition and retention tendencies and self-report measures of hoarding, indecisiveness, and obsessive-compulsive behavior. Our data suggest that decisions about objects, even in a nonclinical undergraduate population, vary widely and are influenced by the same variables that influence clinical hoarding, but to a less extreme degree. Future research with this experimental task can separately investigate the role of acquisition, retention, impulsivity, and sensitivity to constraints in clinical hoarding to inform our understanding of this disorder.

  6. Panic attacks and hoarding disorder: an initial investigation.

    Panic attacks (PAs) defined as a discrete period of intense fear or discomfort, occur in the context of numerous anxiety and mood related disorders. Research has suggested that PAs serve as a significant indicator and prognostic factor for overall symptom severity, course, and comorbidity within various conditions. Consequently, a PA specifier is now applicable to all DSM-5 disorders. Despite these clinical and nosological implications, no research to date has examined associations between PAs and hoarding disorder. The current investigation evaluated relationships between PA endorsement and hoarding severity within a sample of 32 patients with hoarding disorder. Findings suggested a high rate of panic history among those with hoarding disorder (56%). Hoarders with co-occurring PAs, compared to those without PAs, evidenced significantly higher symptom severity. Moreover, PAs continued to significantly predict hoarding severity even after controlling for relevant covariates. When examining the specific relationships among PAs and hoarding symptoms (i.e., acquiring, difficulty discarding, and clutter), the endorsement of PAs was associated with increased acquiring and difficulty discarding symptoms. These findings add considerably to a growing body of literature on hoarding disorder. Implications for the assessment and treatment of PAs that co-occur with hoarding disorder are discussed.

    Hoarding disorder is rarely examined in populations of non-European and/or non-Euro-American descent, especially in East Asian nations like China. Across two studies, the current investigation sets out to examine the psychometric properties of a Chinese version of a widely used measure of hoarding symptoms-the Savings Inventory Revised (SIR)-and to explore the nature of hoarding beliefs compared to a separate US sample. For the first study, 1828 college students in China completed a Mandarin translation of the SIR and measures of anxiety, depression, and obsessive-compulsive disorder. For the second study, 303 students from China and 87 students from the US completed the SIR and a novel hoarding beliefs questionnaire. In the first study, the Chinese-version of the SIR demonstrated convergent and discriminant validity, as well as internal reliability and preliminary construct validity. However, evidence of temporal stability was modest and requires further investigation. In the second study, the Chinese sample endorsed greater hoarding symptoms and hoarding beliefs compared to the US sample, although only themes of usefulness and wastefulness were associated with hoarding in the Chinese samples, whereas a wider range of beliefs was linked with hoarding in the US sample. In addition, the factor structure of the SIR from the first study did not replicate in second study, suggesting that construct validity of the Chinese SIR may require further corroboration. The current study established preliminary evidence for the reliability and validity of the Chinese SIR, although future research is needed to confirm its temporal stability and factor structure. Hoarding beliefs in China may be centered on themes of usefulness and wastefulness compared to more heterogeneous themes in the West, suggesting differential manifestations of hoarding tendencies in cultures of non-European and/or non-Euro-American descent.

  8. Hoarding disorder: a new diagnosis for DSM-V?

    This article provides a focused review of the literature on compulsive hoarding and presents a number of options and preliminary recommendations to be considered for DSM-V. In DSM-IV-TR, hoarding is listed as one of the diagnostic criteria for obsessive-compulsive personality disorder (OCPD). According to DSM-IV-TR, when hoarding is extreme, clinicians should consider a diagnosis of obsessive-compulsive disorder (OCD) and may diagnose both OCPD and OCD if the criteria for both are met. However, compulsive hoarding seems to frequently be independent from other neurological and psychiatric disorders, including OCD and OCPD. In this review, we first address whether hoarding should be considered a symptom of OCD and/or a criterion of OCPD. Second, we address whether compulsive hoarding should be classified as a separate disorder in DSM-V, weighing the advantages and disadvantages of doing so. Finally, we discuss where compulsive hoarding should be classified in DSM-V if included as a separate disorder. We conclude that there is sufficient evidence to recommend the creation of a new disorder, provisionally called hoarding disorder. Given the historical link between hoarding and OCD/OCPD, and the conservative approach adopted by DSM-V, it may make sense to provisionally list it as an obsessive-compulsive spectrum disorder. An alternative to our recommendation would be to include it in an Appendix of Criteria Sets Provided for Further Study. The creation of a new diagnosis in DSM-V would likely increase public awareness, improve identification of cases, and stimulate both research and the development of specific treatments for hoarding disorder.

    In 2013, the American Psychiatric Association published the DSM-5. In this new version, new diagnoses were proposed including the Hoarding disorder. In the French semeiology, the Diogenes syndrome is described, among other symptoms, by a pathological tendency to accumulate objects called syllogomania which is very close to hoarding. This paper explores the similarities and differences between the two syndromes. The Diogenes syndrome was first described in 1966 but was officially named for the ancient Greek philosopher in 1975 by Clark. Its frequency is around five for 100,000 persons. Many aetiologies have been known to be associated with the Diogenes syndrome: schizophrenia, dementia - especially frontotemporal type, anxiety disorders, mood disorders, and substance abuse - especially alcohol abuse. The diagnostic requires one major criterion, the inability to ask for medical or social help, and one of three minor criteria: a pathological relationship to the body, which leads to somatic illness; a pathological relationship to the society, which leads to a progressive exclusion from it; and finally, a pathological link with objects. This last criterion is very interesting because it is closely related to the Hoarding syndrome: indeed, patients with syllogamania, as also named, have a tendency to hoard every object they find. At the end, their homes are full of useless objects, and some living places can be unusable because they are cluttered and congested. This last point is similar to the definition given in the DSM-5 for the Hoarding disorder which describes a persistent difficulty parting with possessions; distress associated with discarding possessions; and accumulations that congest and clutter active living areas. The Hoarding disorder was first part of the Obsessive and compulsive disorders, but it has progressively appeared that it could be individualized with its own prevalence of 2.3% to 14% lifetime. Genetical studies have shown that at least 50% of

    Hoarding is traditionally considered a disorder of adulthood but hoarding symptoms often begin in childhood and adolescence. However, there is very little published research into hoarding in youth. As described in this commentary, the study of hoarding in childhood and adolescence is important because hoarding symptoms: 1) often begin in childhood and adolescence; 2) often are chronic and persist into adulthood; and, 3) are associated with a number of negative outcomes and sequelae. Research into hoarding in youth could help identify individuals at risk for chronic and persistent hoarding disorder as well as determine interventions to change their trajectories. Improved understanding of hoarding in children and adolescents could in turn help minimize the negative effect of hoarding on the affected individuals, their families and society. PMID:26379725

    Research on the cognitive variables associated with obsessive-compulsive hoarding is scarce. In this study, we investigated cognitive variables that may contribute to the maintenance and possibly etiology of hoarding. College students who characterized themselves as either "packrats" (nonclinical hoarders; n=21) or not (control participants; n=20) completed questionnaires assessing hoarding behavior and beliefs about hoarding, and completed a task requiring them to categorize diverse objects and trinkets of minimal value into groups. The results revealed that nonclinical hoarders, relative to control participants, rated the categorization task as significantly more stressful and difficult. Relative to control participants, hoarders took longer to complete the task and sorted objects into more categories. These findings suggest that underinclusiveness and indecisiveness, characteristic of clinical hoarders, are evident in nonclinical hoarders as well.

  1. The coin hoard of Abasár

    Full Text Available The composition of the small hoard found on the northern edge of the Great Plain is very interesting and unique in Hungary, as Celtic tetradrachms and small change were hidden along with Roman Republican and Imperial denarii. The peculiar composition of the hoard suggests the treasure was aggregated by several generations of the owner’s family. The silver ingot indicates that the hoard was treated as bullion rather than money, which attests the lack of regular coin circulation in the Celtic Carpathian basin. The Lapujtő type coins of the hoard denote eastern connections, they probably mark the arrival of Celts fled before the Dacians. The Roman coins might indicate the establishment of an ally system as a part of the Augustean foreign politics, and based on the coins it existed even during the reign of Tiberius.

    Intolerance of uncertainty (IU) has been identified as a key vulnerability factor among numerous anxiety related conditions. It has been suggested that individuals engage in uncertainty-motivated behaviors such as avoidance, as a way to cope with ambiguous and potentially distressing situations. Patterns of behavioral avoidance have also been observed in a substantial number of hoarding patients and are thought to directly contribute to the avoidance of discarding. However, no studies to date have examined the potential relationship between IU and hoarding. The primary aim of the current investigation was to examine the association between IU and hoarding behaviors. Participants consisted of 279 college students from a large southern university. Results revealed that IU was a significant predictor of hoarding severity after controlling for relevant covariates. Moreover, when looking at the relationships among IU subfactors and hoarding, results indicated that Factor 1 was significantly associated with hoarding severity whereas Factor 2 was not. Future research should attempt to replicate the findings within clinical populations. Additionally, due to the cross sectional nature of the study, future work should utilize a longitudinal design. The current study provides additional evidence that IU is an important individual difference variable associated with various anxiety related conditions. Moreover, our findings revealed that IU is a unique and robust predictor of hoarding behaviors. Increasing our knowledge of vulnerability factors in compulsive hoarding has important implications for the classification of this disorder within DSM-V. Additionally, this information could inform future research and treatment programs. Copyright © 2012 Elsevier B.V. All rights reserved.

    2014-01-01

    Full Text Available Despite the long-held view that hoarding is a symptom of both obsessive-compulsive disorder and obsessive-compulsive personality disorder, increased evidence has emerged during the last 20 years suggesting that hoarding represents a distinct form of psychopathology. This study reflects the discussions on the nosological status of hoarding carried out by the WHO ICD-11 Working Group on the Classification of Obsessive-Compulsive and Related Disorders. The distinctiveness of hoarding is based on its having core symptoms that differ from those of other disorders, as well as distinctive neurobiological correlates and treatment responses. Furthermore, data showing the clinical utility, global applicability, and appropriateness of the concept of hoarding disorder outside specialty mental health settings suggest that this condition should be included in ICD-11. Finally, given the focus of ICD-11 on primary care and public health, the Working Group suggests that poor insight and severe domestic squalor may be considered as specifiers for hoarding disorder in ICD-11.

    2010-04-01

    Compulsive hoarding has been studied primarily in Western countries. Here we sought to examine compulsive hoarding in Japanese patients with obsessive-compulsive disorder (OCD). The heterogeneous nature of hoarding was also investigated. One hundred and sixty-eight OCD outpatients were initially assessed to determine the presence or absence of compulsive hoarding, and whether hoarding was primary or secondary to another symptom dimension for which they had received treatment for 1 year. Of the participants, 54 patients were found to have compulsive hoarding. Hoarders were significantly more likely than non-hoarding patients to have more severe psychopathology including elevated severity of OCD symptoms, poorer insight, higher prevalence of comorbid schizotypal or obsessive-compulsive personality disorder, closer association with symmetry dimension, and poorer treatment outcome. Comparisons of subjects with primary and secondary hoarding found that the former group had more severe clinical features, while the latter group hoarded a wider variety of items, including apparently bizarre ones. The prevalence and clinical characteristics of compulsive hoarding in OCD subjects was similar to those reported in Western countries, supporting its trans-cultural consistency. The distinction between primary and secondary hoarding in OCD is clinically useful, and may contribute to the debate about whether hoarding should be a separate diagnostic entity.

    2015-10-01

    This study aimed to test which particular facets of emotion regulation (ER) are most linked to symptoms of hoarding disorder, and whether beliefs about emotional attachment to possessions (EA) mediate this relationship. A non-clinical sample of 150 participants (108 females) completed questionnaires of emotional tolerance (distress tolerance, anxiety sensitivity, negative urgency - impulsivity when experiencing negative emotions), depressed mood, hoarding, and beliefs about emotional attachment to possessions. While all emotional tolerance measures related to hoarding, when considered together and controlling for depression and age, anxiety sensitivity and urgency were the significant predictors. Anxiety sensitivity was fully mediated, and urgency partially mediated, via beliefs regarding emotional attachment to possessions. These findings provide further support for (1) the importance of anxiety sensitivity and negative urgency for hoarding symptoms, and (2) the view that individuals with HD symptoms may rely on items for emotion regulation, leading to stronger beliefs that items are integral to emotional wellbeing. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  18. Physiological mechanisms for food-hoarding motivation in animals

    Science.gov (United States)

    Keen-Rhinehart, Erin; Dailey, Megan J.; Bartness, Timothy

    2010-01-01

    The study of ingestive behaviour has an extensive history, starting as early as 1918 when Wallace Craig, an animal behaviourist, coined the terms ‘appetitive’ and ‘consummatory’ for the two-part sequence of eating, drinking and sexual behaviours. Since then, most ingestive behaviour research has focused on the neuroendocrine control of food ingestion (consummatory behaviour). The quantity of food eaten, however, is also influenced by the drive both to acquire and to store food (appetitive behaviour). For example, hamster species have a natural proclivity to hoard food and preferentially alter appetitive ingestive behaviours in response to environmental changes and/or metabolic hormones and neuropeptides, whereas other species would instead primarily increase their food intake. Therefore, with the strong appetitive component to their ingestive behaviour that is relatively separate from their consummatory behaviour, they seem an ideal model for elucidating the neuroendocrine mechanisms underlying the control of food hoarding and foraging. This review focuses on the appetitive side of ingestive behaviour, in particular food hoarding, attempting to integrate what is known about the neuroendocrine mechanisms regulating this relatively poorly studied behaviour. An hypothesis is formed stating that the direction of ‘energy flux’ is a unifying factor for the control of food hoarding. PMID:20156819

    Full Text Available ABSTRACT Hoarding is considered (Ihtikar very abhorring and objectionable. It is the practice of keeping something in store and not bringing the same to the market so that prices may rise owing to this artificial dearth of supply in the market. Each religion of the world has agriculture rules. In these, rules about Hoarding play an important role. In non Semitic religions Hinduism is the largest religion of the world. Similarly in Semitic religions Islam is the second and Judaism is considered in third stage. All these three religions and there followers have good relation with agriculture .But among this, Islamic rules considers one of the best rules in the world. Because Hinduism agriculture rules affected by cast system and the other side Judaism rules is affected by customs and traditions. But still there are some points on which Hinduism, Judaism and Islam are completely supporting each others. Hoarding rules is one of them. This paper is consisting on hoarding rules in Hinduism, Judaism and Islam.

    2017-01-01

    Hoarding disorder is characterized by difficulty discarding or parting with possessions regardless their actual value as well as, in most cases, persistent acquisition of objects. Possessions are accumulated in large numbers that fill up and clutter active living space to the extent that its intended use is no longer possible resulting to significant functional impairment and/or distress. Saving and difficulty discarding appear to be associated to subjective beliefs about the instrumental, sentimental or intrinsic value of objects. Despite significant impact on the individual, the family and the community, until recently hoarding disorder had been a "neglected" clinical phenomenon. The recent research efforts to study and understand this phenomenon led to significant changes regarding the diagnostic status and therapeutic interventions. It was classified as a distinct diagnostic entity in the recent edition of the Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association-5th ed. (DSM-5). Hoarding is not considered a symptom of obsessive compulsive disorder or obsessive compulsive personality disorder anymore and it is now ranked among compulsive spectrum disorders. So far the cognitive model for hoarding disorder is the main, widely accepted, clinically and empirically supported theoretical framework for understanding its features. The cognitive model offers an explanation about the predisposing, onset and perpetuating factors of the disorder as well as the basis for the development of specific therapeutic interventions. The cognitive model conceptualizes hoarding disorder as a result of four factors: personal vulnerability (heredity, early experiences and life events, personality traits, interpersonal difficulties), difficulties in information processing (deficits in attention, memory, executive functions such as decision making and categorization), maladaptive cognitive content (meaning of possessions, emotional attachment to

    2015-04-01

    Effective management of Hoarding Disorder (HD) must begin with assessment of the severity of hoarding symptoms and functional impairment. We sought to validate the UCLA Hoarding Severity Scale (UHSS), a semi-structured, clinician-administered rating scale that measures the severity of both the core symptoms of HD and the associated features of indecisiveness, perfectionism, task prolongation, and procrastination, which are significantly associated with the diagnosis and impairment of HD. Hoarding symptom severity was measured in 62 patients who met DSM-5 diagnostic criteria for HD and 65 normal controls, using the UHSS and the Saving Inventory-Revised (SI-R), a well validated self-report measure of hoarding symptoms. The UHSS showed significant internal consistency (Cronbach׳s α=.70). Principal components analysis revealed three factors that accounted for 58% of the variance: 1) associated features and functional impairment, 2) clutter volume and social impairment, and 3) difficulty discarding, urges to save, and excessive acquisition. UHSS and SI-R scores were significantly correlated. UHSS and SI-R total and factor scores of HD patients were all significantly different from those of controls. Inter-rater and test-retest reliability were not assessed. The initial version of the UHSS did not contain rater instructions, so it lacked quantifiable anchor points for ratings. The UHSS showed internal consistency, construct validity, convergent validity, and known groups discriminant validity. The UHSS validly measures the core symptoms, associated features, and functional impairment of patients with HD. Utilizing a valid clinician-administered scale will provide a more comprehensive and accurate clinical assessment of patients with HD. Copyright © 2015 Elsevier B.V. All rights reserved.

    1999-09-01

    We describe the demographic characteristics, hoarding phenomenology, comorbid disorders, family histories, and treatment response of 20 adult obsessive-compulsive disorder (OCD) patients exhibiting hoarding behavior. We utilized the Structured Clinical Interview for DSM-III-R, the Yale-Brown Obsessive Compulsive Scale, and a semistructured interview to gather data. We studied 9 women and 11 men. Their hoarding began from age 5 years to age 46 years (mean +/- SD age at onset = 20 +/- 11 years); hoarding was evident before the onset of other OCD symptoms in 9 patients. The most commonly hoarded items were newspapers and magazines, junk mail, old clothes, notes or lists, and old receipts. Hoarded material occupied from one room plus most or all closets to more than one room plus all closets, the garage, and yard. Seven patients rented additional storage space for hoarded items. Eighty-four percent of patients reported a family history of hoarding, and 80% grew up in a household where someone else hoarded. The most frequent primary motives for hoarding were fears of discarding something useful and discarding something that would be needed in the future. Lifetime prevalence of major depression and of impulse-control disorders, especially compulsive shopping, were high; only 3 patients met DSM-IV criteria for obsessive-compulsive personality disorder. Response of hoarding to selective serotonin reuptake inhibitors was less robust than is expected for obsessive-compulsive disorder. Whether hoarding behaviors mark a subset of obsessive-compulsive disorder patients with a different pathophysiology or functional anatomy deserves investigation.

    Food hoarding helps animals to maintain their physical condition during times of food scarcity. Wolverines (Gulo gulo) inhabitat mostly environments of low productivity, and are known to hoard food for long-term periods, to store a single food item per food cache, and to spatially spread their food caches across their home range.

They switched to hoarding large international reserves when growth faltered, making it harder to disentangle the...

    2009-08-01

    The aims of the study were to estimate the prevalence rate of compulsive hoarding, and to determine the association between compulsive hoarding and compulsive buying in a nationally representative sample of the German population (N = 2307). Compulsive hoarding was assessed with the German version of the Saving Inventory-Revised (SI-R; Frost, R.O., Steketee, G., & Grisham, J. (2004). Measurement of compulsive hoarding: saving inventory-revised. Behaviour Research and Therapy, 42, 1163-1182.). The point prevalence of compulsive hoarding was estimated to be 4.6%. Individuals with compulsive hoarding did not differ significantly from those without compulsive hoarding regarding age, gender, and other sociodemographic characteristics. Significant correlations were found between the compulsive hoarding and the compulsive buying measures. Participants with compulsive hoarding reported a higher propensity to compulsive buying than respondents without hoarding. About two thirds of participants classified as having compulsive hoarding were also defined as suffering from compulsive buying. In summary, these results suggest that compulsive hoarding may be relatively prevalent in Germany and they confirm the close association between compulsive hoarding and compulsive buying through the investigation of a large scale representative sample.

    2015-08-01

    This paper considers the meaning of the terms hoarding, collecting and accumulation, with a focus on what is abnormal and what is not. Hoarding is an adaptive behaviour. When hoarding is excessive and interferes with people's lives, it is a disorder. A central feature of hoarding disorder is accumulation of items due to unwillingness to discard them. This must be distinguished from abnormal accumulation of material caused by poor motivation or unawareness concerning the need to discard. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Overconfidence is a well-established behavioral phenomenon that involves an overestimation of own capabilities. We introduce a model, in which managers and agents exert effort in a joint production, after the manager decides on the allocation of the tasks. A rational manager tends to delegate the critical task to the agent more often than given by the efficient task allocation. In contrast, an overconfident manager is more likely to hoard responsibility, i.e. to delegate the critical task les...

    Full Text Available We describe the Temperament and Character Inventory personality traits, demographic features, physical and mental health variables associated with hoarding behaviour in a random community sample of midlife participants in New Zealand. A sample of 404 midlife participants was recruited to a study of ageing. To assess hoarding behaviours participants completed the Savings Inventory-Revised (SI-R, personality was assessed by the Temperament and Character Inventory and self-reported health was measured by the Short Form-36v2 (SF-36v2. Other measures were used to assess socio-demographic variables and current mental disorders. Participants were split into four groups by SI-R total score (scores: 0–4, 5–30, 31–41 and >41. Those who scored >41 on the SI-R were classified as having pathological hoarding. Trend tests were calculated across the four hoarding groups for socio-demographic, personality, mental and physical health variables. SI-R scores ranged from 0 to 58. The prevalence of pathological hoarding was 2.5% and a further 4% reported sub-clinical symptoms of hoarding. Higher hoarding behaviour scores were related to higher Temperament and Character Inventory scores for Harm Avoidance and lower scores for Self-directedness. Persistence and Cooperativeness scores were lower too but to a lesser extent. Trend analysis revealed that those with higher hoarding behaviour scores were more likely to be single, female, unemployed, receive income support, have a lower socio-economic status, lower household income and have poorer self-reported mental health scores. Current depression rates were considerably higher in the pathological hoarding group. Increasing SI-R hoarding behaviour scores were associated with higher scores of negative affect (Harm Avoidance and lower scores of autonomy (Self-directedness. Those with pathological hoarding or sub-clinical symptoms of hoarding also reported widespread mental and socio-economic problems. In this study

    The feeding behavior of the deer mouse, Peromyscus maniculatus, includes food hoarding as well as ingestion. In this animal the mu opiate agonist, morphine, and the kappa opiate agonist, U-50, 488H, selectively stimulate food hoarding and ingestion, respectively. This suggests that mu and kappa opiate systems may differentially mediate primary components of natural feeding behavior.

    During the past decade, many community task forces have formed to address hoarding problems that come to public attention. Such task forces provide a societal-level intervention to assist people with the most severe cases of hoarding, who do not voluntarily seek or want help for their hoarding behaviour. This qualitative study of five U.S. hoarding task forces included sites selected for their diversity of purpose, approaches to hoarding intervention and community geography, composition and resources. Data were collected during the period of September 2007-March 2008. The case study methodology used multiple forms of data, including semi-structured interviews, analysis of documents, small group interviews and investigator observation. This study captured the perspectives of public and private sector service providers such as mental health, housing, social service, public health agencies and community enforcement organisations (fire, police, legal, animal control) to examine how task forces organise and operate and the emerging practice and policy changes. Study findings suggest that structural factors (e.g. leadership, purpose, funding and membership) impact hoarding task force viability, that participation on a task force influences practice and policy decisions about hoarding, and that social work can expand its role in task force leadership. Task forces may be a mechanism for improving community policies about hoarding and mechanisms for addressing other social problems across multiple sectors. © 2012 Blackwell Publishing Ltd.

    Möllenkamp, Maike; de Zwaan, Martina; Müller, Astrid

    2015-01-01

    Previous research demonstrated a close relationship between hoarding disorder (compulsive hoarding, CH) and compulsive buying (CB). Hoarding disorder was included in the 5th version of the Diagnostic and Statistical Manual of Mental Disorders (APA, 2013) with excessive acquisition as a specifier. This pilot study aimed to investigate whether individuals with both hoarding and buying symptoms (CBCH group) will present with the highest severity levels of hoarding as well as buying psychopathology compared to the respective group exhibiting only one syndrome (CH group: only hoarding, CB group: only buying). The three groups (CH: n = 40, CBCH: n = 60, CB: n = 35) completed the Saving Inventory-Revised, the Compulsive Acquisition Scale und the Compulsive Buying Scale. Data were analysed using non-parametric tests. The CBCH group did not differ from the CH group with regard to the severity of key hoarding symptoms such as clutter, difficulty discarding possessions, and the acquisition of free things, but showed a higher severity of CB than the CB group. While the findings indicate remarkable overlap in primary features of CH in compulsive hoarders with and without excessive buying, they suggest more severe CB in individuals with both hoarding and buying symptoms compared to individuals with only CB. Future studies should address the question whether both disorders are part of a larger construct. © 2014 S. Karger AG, Basel.

    2012-09-01

    Hoarding behavior, long considered a symptom of obsessive-compulsive disorder (OCD) in the Diagnostic and Statistical Manual (DSM-IV-TR; American Psychiatric Association, 2000), has recently garnered significant attention and has only begun to be more carefully studied and understood. Recent research reveals that hoarding is frequently comorbid with anxiety, depression, and other diagnoses, including OCD. The DSM-5 Working Group on Anxiety, Obsessive-Compulsive Spectrum, Posttraumatic, and Dissociative Disorders is currently working to determine appropriate placement of hoarding in the DSM-5 (APA, 2010), and has tentatively proposed the term Hoarding Disorder to be used as a new and unique diagnosis. The purpose of this paper is to provide some insight into the evidence base that has prompted this change and to familiarize clinicians with research and best practices in the emerging field of diagnosing and treating hoarding behaviors.

    2017-07-01

    Individuals with ADHD and comorbid hoarding disorder are vulnerable to severe consequences from hoarding symptoms. Despite this, and the early onset of hoarding disorder, the nature of hoarding symptoms in children with comorbid ADHD is unknown. We therefore explored the phenomenology of hoarding symptoms among ten 8-12year olds with ADHD and clinically significant hoarding symptoms through parental perceptions. Parents completed in-depth semi-structured interviews. The data was analyzed using Interpretative Phenomenological Analysis. Six superordinate themes were identified: emotional distress; parental avoidance and accommodating behaviors; family impacts of hoarding; excessive acquisition and saving; executive functioning; parental insight and intervention. In contrast to previous suggestions that emotional distress was not associated with hoarding in ADHD, these findings highlight that emotional distress appeared to be core to the hoarding disorder profile of the present sample of children with ADHD. This has important implications for health practitioners who may consider conceptualizing, assessing, and treating hoarding symptoms in children with comorbid ADHD using a cognitive behavioral model of hoarding disorder.

    Hoarding disorder (HD) is a chronic and debilitating psychiatric condition. Midlife HD patients have been found to have neurocognitive impairment, particularly in areas of executive functioning, but the extent to which this is due to comorbid psychiatric disorders has not been clear. The purpose of the present investigation was to examine executive functioning in geriatric HD patients without any comorbid Axis I disorders (n = 42) compared with a healthy older adult comparison group (n = 25). We hypothesized that older adults with HD would perform significantly worse on measures of executive functioning (Wisconsin Card Sort Task [Psychological Assessment Resources, Lutz, Florida, USA] ( Psychological Assessment Resources, 2003) and the Wechsler Adult Intelligence Scale-IV digit span and letter-number sequencing tests [Pearson, San Antonio, TX, USA]). Older adults with HD showed significant differences from healthy older controls in multiple aspects of executive functioning. Compared with healthy controls, older adults with HD committed significantly more total, non-perseverative errors and conceptual level responses on the Wisconsin Card Sort Task and had significantly worse performance on the Wechsler Adult Intelligence Scale-IV digit span and letter-number sequencing tests. Hoarding symptom severity was strongly correlated with executive dysfunction in the HD group. Compared with demographically-matched controls, older adults with HD have dysfunction in several domains of executive functioning including mental control, working memory, inhibition, and set shifting. Executive dysfunction is strongly correlated with hoarding severity and is not because of comorbid psychiatric disorders in HD patients. These results have broad clinical implications suggesting that executive functioning should be assessed and taken into consideration when developing intervention strategies for older adults with HD.

    Group cognitive behavioral treatments (GCBTs) for hoarding have produced modest benefits. The current study examined whether the outcomes of a specialized GCBT improve upon bibliotherapy (BIB) for hoarding, as part of a stepped care model. We also explored whether additional home assistance enhanced GCBT outcomes. Hoarding patients (n = 38) were randomized and completed one of three conditions: (1) GCBT with nonclinician home assistants (GCBT+HA; N = 11), (2) GCBT without HA (CGBT; N = 14), and (3) BIB (N = 13). All GCBT participants received 20 weekly group sessions and four home visits by a group co-therapist. GCBT+HA groups received four additional visits by a nonclinician coach. BIB participants were assigned a self-help book describing specific skills to reduce hoarding over the 20-week period. All participants were assessed by self-report at baseline, mid-treatment, and posttreatment. The sample averaged 57 years old and was mainly female, White, highly educated, employed, and living alone. GCBT+HA and GCBT participants showed significant reductions on hoarding and depression symptoms, whereas BIB did not. GCBT+HA and GCBT benefited substantially and similarly on the saving inventory-revised (reductions of 29.9 and 23.3%, respectively) and SI-R (Saving Inventory-Revised) (reductions of 26.5 and 25.4%), whereas BIB participants showed very limited improvement (9% reduction) on both measures. This study provides support for the efficacy of GCBT for hoarding. The effect of adding nonclinician home assistance was not significant in this small sample. BIB was not sufficient to improve hoarding symptoms. The findings have implications for a stepped care model for treating hoarding (e.g., the benefits of psycho-education via BIB, added benefits of extra in-home visits) and suggest the need to further examine the role of in-home hoarding coaches. © 2012 Wiley Periodicals, Inc.

    Current models of hoarding disorder (HD) emphasize problems of decision-making. Evidence for neuropsychological impairment in HD, however, has been mixed. The present study examined whether HD patients show problems of economic reasoning that could be associated with decision-making problems. Forty-two HD patients, 29 obsessive-compulsive disorder (OCD) patients, and 36 healthy control participants completed the Iowa gambling task (IGT), a computerized card playing game that assesses participants' ability to learn and utilize a rule of sacrificing short-term gain for long-term gain, and a cognitive dissonance reduction task that measured changes in preference for items (art prints) after selecting or rejecting them. Results showed no deficits on the IGT for HD participants, and no difference in dissonance reduction results after selecting or rejecting items on the dissonance reduction task. Furthermore, performance on these two tasks was unrelated to hoarding symptom severity or self-reported indecisiveness. It is suggested that the problems of cognitive processing in HD patients may be largely related to as-yet understudied processes, including idiosyncratic categorization problems for personally-owned items as well as other aspects of economic reasoning.

    Hoarding in children is associated with more severe ancillary psychopathology, and has poor treatment outcome. At present, there are no empirically established procedures for treating hoarding in youth. The present case illustration is of a 10-year old child ("Grace") who presented for treatment with significant hoarding related to academic concerns and additional unrelated symptoms of obsessive-compulsive disorder (OCD). Grace was treated with cognitive behavior therapy (CBT) primarily comprising exposure with response prevention, behavioral experiments, and cognitive therapy, along with a program of reinforcement delivered by her parents to maintain her motivation for therapy. After 23 sessions and one booster session, Grace's symptoms improved significantly, with gains maintained at 1-year follow-up. In addition to the benefits of the specific interventions chosen, the role of therapist-patient/parent alliance as a contributory factor for good outcome is emphasized. As hoarding is underinvestigated in youth, suggestions for further investigation are offered. © 2016 Wiley Periodicals, Inc.

    In the present study, we investigated whether the relationship between identity confusion and compulsive buying (offline/online) and hoarding is mediated by materialistic value endorsement and depression. The community sample consisted of 254 Flemish adults who completed self-report questionnaires to assess identity confusion (Erikson Psychosocial Stage Inventory), compulsive buying tendencies (Compulsive Buying Scale/short-Internet Addiction Scale, adapted for shopping), hoarding tendencies (Saving-Inventory Revised), materialistic value endorsement (Materialistic Value Scale), and depression (Patient Health Questionnaire-9). We found significant positive associations between identity confusion, compulsive buying, and hoarding. The association between identity confusion and compulsive buying was fully mediated by materialistic value endorsement; whereas depression mediated the association between identity confusion and hoarding. The results suggest that the collection or buying of material goods can be considered as identity substitutes. Copyright © 2016 Elsevier Inc. All rights reserved.

    Hoarding is a serious form of psychopathology that has been associated with significant health and safety concerns, as well as the source of social and economic burden (Tolin, Frost, Steketee, & Fitch, 2008; Tolin, Frost, Steketee, Gray, & Fitch, 2008). Recent developments in the treatment of hoarding have met with some success for both individual and group treatments. Nevertheless, the cost and limited accessibility of these treatments leave many hoarding sufferers without options for help. One alternative is support groups that require relatively few resources. Frost, Pekareva-Kochergina, and Maxner (2011) reported significant declines in hoarding symptoms following a non-professionally run 13-week support group (The Buried in Treasures [BIT] Workshop). The BIT Workshop is a highly structured and short term support group. The present study extended these findings by reporting on the results of a waitlist control trial of the BIT Workshop. Significant declines in all hoarding symptom measures were observed compared to a waitlist control. The treatment response rate for the BIT Workshop was similar to that obtained by previous individual and group treatment studies, despite its shorter length and lack of a trained therapist. The BIT Workshop may be an effective adjunct to cognitive behavior therapy for hoarding disorder, or an alternative when cognitive behavior therapy is inaccessible. Copyright © 2012 Elsevier Ltd.

    Spatial memory of cached food items plays an important role in cache recovery by scatter-hoarding animals. However, whether scatter-hoarding animals intentionally select cache sites with respect to visual landmarks in the environment and then rely on them to recover their cached seeds for later use has not been extensively explored. Furthermore, there is a lack of evidence on whether there are sex differences in visual landmark-based food-hoarding behaviors in small rodents even though male and female animals exhibit different spatial abilities. In the present study, we used a scatter-hoarding animal, the Siberian chipmunk, Tamias sibiricus to explore these questions in semi-natural enclosures. Our results showed that T. sibiricus preferred to establish caches in the shallow pits labeled with visual landmarks (branches of Pinus sylvestris, leaves of Athyrium brevifrons and PVC tubes). In addition, visual landmarks of P. sylvestris facilitated cache recovery by T. sibiricus. We also found significant sex differences in visual landmark-based food-hoarding strategies in Siberian chipmunks. Males, rather than females, chipmunks tended to establish their caches with respect to the visual landmarks. Our studies show that T. sibiricus rely on visual landmarks to establish and recover their caches, and that sex differences exist in visual landmark-based food hoarding in Siberian chipmunks. © 2015 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

    Hoarding disorder is a new mental disorder in DSM-5. It is classified alongside OCD and other presumably related disorders in the Obsessive-Compulsive and Related Disorders chapter. We examined cognitive performance in two distinct groups comprising individuals with both OCD and severe hoarding, and individuals with hoarding disorder without comorbid OCD. Participants completed executive function tasks assessing inhibitory control, cognitive flexibility, spatial planning, probabilistic learning and reversal and decision making. Compared to a matched healthy control group, OCD hoarders showed significantly worse performance on measures of response inhibition, set shifting, spatial planning, probabilistic learning and reversal, with intact decision making. Despite having a strikingly different clinical presentation, individuals with only hoarding disorder did not differ significantly from OCD hoarders on any cognitive measure suggesting the two hoarding groups have a similar pattern of cognitive difficulties. Tests of cognitive flexibility were least similar across the groups, but differences were small and potentially reflected subtle variation in underlying brain pathology together with psychometric limitations. These results highlight both commonalities and potential differences between OCD and hoarding disorder, and together with other lines of evidence, support the inclusion of the new disorder within the new Obsessive-Compulsive and Related Disorders chapter in DSM-5.

    Full Text Available Transitioning collectibles from the physical to the digital sphere changes the culture of collecting by increasing the accessibility of trading partners and adding digital limitations on personal interaction. In this analysis, I examine the collecting game Star Wars Card Trader (2015 and its culture of mass hoarding—the collecting of vast quantities of a single, valueless digital object—through which players reintroduce elements of personality, camaraderie, and nonrivalrous collecting into a system designed primarily for anonymous profitable acquisition. Via an analysis of player behaviors both within the game itself and in online venues, I argue that mass hoarding—a user invention—acts as the central community-building behavior in this digital realm. Mass hoarding is thus a clear indication that even in the digital realm, human personalities and relationships are vital to the construction of collecting as a pastime that is more complex than an investment opportunity.

  20. Prevalence, comorbidity and heritability of hoarding symptoms in adolescence: a population based twin study in 15-year olds.

    Full Text Available Hoarding Disorder (HD is often assumed to be an 'old age' problem, but many individuals diagnosed with HD retrospectively report first experiencing symptoms in childhood or adolescence. We examined the prevalence, comorbidity and etiology of hoarding symptoms in adolescence.To determine the presence of clinically significant hoarding symptoms, a population-based sample of 15-year old twins (N = 3,974 completed the Hoarding Rating Scale-Self Report. Co-occurring Obsessive Compulsive Disorder (OCD, Autism Spectrum Disorders (ASD and Attention Deficit Hyperactivity Disorder (ADHD were estimated from parental report. Model-fitting analyses divided hoarding symptom scores into additive genetic, shared, and non-shared environmental effects.The prevalence of clinically significant hoarding symptoms was 2% (95% CI 1.6-2.5%, with a significantly higher prevalence in girls than boys. Exclusion of the clutter criterion (as adolescents do not have control over their environment increased the prevalence rate to 3.7% (95% CI 3.1-4.3%. Excessive acquisition was reported by 30-40% among those with clinically significant hoarding symptoms. The prevalence of co-occurring OCD (2.9%, ASD (2.9% and ADHD (10.0% was comparable in hoarding and non-hoarding teenagers. Model-fitting analyses suggested that, in boys, additive genetic (32%; 95% CI 13-44% and non-shared environmental effects accounted for most of the variance. In contrast, among girls, shared and non-shared environmental effects explained most of the variance, while additive genetic factors played a negligible role.Hoarding symptoms are relatively prevalent in adolescents, particularly in girls, and cause distress and/or impairment. Hoarding was rarely associated with other common neurodevelopmental disorders, supporting its DSM-5 status as an independent diagnosis. The relative importance of genetic and shared environmental factors for hoarding differed across sexes. The findings are suggestive of

    Hoarding disorder (HD), previously considered a subtype of obsessive-compulsive disorder (OCD), has been proposed as a unique diagnostic entity in DSM-5. Current models of HD emphasize problems of decision-making, attachment to possessions, and poor insight, whereas previous neuroimaging studies have suggested abnormalities in frontal brain regions. To examine the neural mechanisms of impaired decision making in HD in patients with well-defined primary HD compared with patients with OCD and healthy control subjects (HCs). We compared neural activity among patients with HD, patients with OCD, and HCs during decisions to keep or discard personal possessions and control possessions from November 9, 2006, to August 13, 2010. Private, not-for-profit hospital. A total of 107 adults (43 with HD, 31 with OCD, and 33 HCs). Neural activity as measured by functional magnetic resonance imaging in which actual real-time and binding decisions had to be made about whether to keep or discard possessions. Compared with participants with OCD and HC, participants with HD exhibited abnormal activity in the anterior cingulate cortex and insula that was stimulus dependent. Specifically, when deciding about items that did not belong to them, patients with HD showed relatively lower activity in these brain regions. However, when deciding about items that belonged to them, these regions showed excessive functional magnetic resonance imaging signals compared with the other 2 groups. These differences in neural function correlated significantly with hoarding severity and self-ratings of indecisiveness and "not just right" feelings among patients with HD and were unattributable to OCD or depressive symptoms. Findings suggest a biphasic abnormality in anterior cingulate cortex and insula function in patients with HD related to problems in identifying the emotional significance of a stimulus, generating appropriate emotional response, or regulating affective state during decision making.

    Objective Hoarding disorder (HD) is an often incapacitating psychiatric illness associated with a wide range of neurocognitive abnormalities. Some prior neuropsychological studies have found executive dysfunction in HD, but no clear pattern has emerged. One potential reason for discrepant results in previous studies might be the inclusion of patients on psychotropic and other medications that can affect neurocognitive performance. Therefore, we examined neurocognitive functioning in medication-free HD patients. We also added a novel investigation of implicit learning, which has been found to be abnormal in obsessive-compulsive disorder (OCD) and related disorders. Method 26 participants meeting DSM-5 diagnostic criteria for HD and 23 normal controls were administered a battery of neuropsychological tests and symptom rating scales. All participants were free of psychotropic medications for at least six weeks prior to the study. Results HD participants showed no significant differences from normal controls on measures of verbal memory, attention, or executive functioning, including response inhibition, planning, organization, and decision-making. However, HD participants demonstrated a trend toward less implicit learning and greater use of explicit learning strategies during perceptual categorization, compared to normal controls. HD participants who used an implicit strategy performed significantly worse than controls who used an implicit strategy. Hoarding symptom severity was not associated with neurocognitive performance. Conclusions HD patients may have a tendency to use explicit rather than implicit learning strategies for perceptual categorization but perform as well as normal controls on many other neurocognitive measures. Future studies should assess unmedicated participants and examine test strategies, not just outcomes. PMID:26301774

  3. Food hoarding, but not food intake, is attenuated by acute diazepam treatment in female Mongolian gerbils (Meriones unguiculatus).

    Yang, Hui-Di; Wang, Qian; Wang, De-Hua

    2014-06-01

    This article is part of a Special Issue "Energy Balance". Effects of γ-aminobutyric acid (GABA) on food hoarding are unknown in rodents, and the effects of energy balance and GABA have not been evaluated in females. To evaluate the role of food deprivation and GABA on food hoarding, female Mongolian gerbils were given i.p. injection of diazepam (1mg/kg and 3mg/kg, respectively), a GABAA receptor agonist. Among food-deprived females, there was a bimodal pattern in the frequency of gerbils with different levels of food hoarding. High food hoarding (HFH) and low food hoarding (LFH) gerbils were analyzed. Diazepam blocked food deprivation-induced food hoarding in HFH gerbils, but not in LFH gerbils. This blockade was associated with increased cellular activation in selected brain areas, such as the nucleus accumbens (NAcc), caudate putamen (CP) and ventral tegmental area (VTA), which suggested that direct activation of GABA in the brain reward circuitry decreased food hoarding in HFH females. Moreover, diazepam increased Fos expression in field CA2 and CA3 of the hippocampus, but had no significant effect on Fos expression in field CA1 and dentate gyrus (DG) of the hippocampus, indicating that the hippocampus has area-specific effects on food hoarding in HFH gerbils. Diazepam did not alter food intake in both HFH and LFH gerbils. In addition, serum corticosterone concentrations were higher in the HFH than in the LFH ones. Together, these data indicated that food deprivation increased food hoarding in female gerbils, diazepam reduced food deprivation-induced food hoarding in HFH gerbils, and that GABA might influence food hoarding via classical reward circuitry via the mesolimbic dopamine system and specific hippocampal areas.

  4. Hoarding disorder and the legal system: A comparative analysis of South African and Dutch law.

    Science.gov (United States)

    Cramer, Richard; Vols, Michel

    Hoarding is an internationally recognised disability. Those who suffer from hoarding behaviour can be comfortably brought within the definition of disability found in the Convention on the Rights of Persons with Disabilities and should be provided with "reasonable accommodation" where doing so does not place an unjustified burden on others. However, hoarding also poses a threat to public health, and hoarders' behaviour may infringe on the rights of their neighbours and landlords. Thus, through their behaviour, hoarders may ultimately come into conflict with various areas of law, including neighbour law, housing law as well as administrative law. This article examines how hoarding may be addressed by the law in both South Africa and the Netherlands. It seeks to answer to what extent hoarders are provided with "reasonable accommodation" when their behaviour brings them into conflict of the law in these two jurisdictions. It also takes cognisance of the need to balance the provision of "reasonable accommodation" with the rights of neighbours and landlords. Finally, it seeks to assess which of the two jurisdictions provides the most balanced approach to handling hoarding, in light of the need for therapeutic jurisprudence. Copyright © 2016 Elsevier Ltd.

    Dementia and its associated problem behaviors remain bothersome to family and professional caregivers. Exploring characteristics and the underlying meaning of disruptive behaviors in elders with Alzheimer's dementia can be a first step to pursuing patient-centered care. Although hoarding is relatively harmless, unattended excessive hoarding can create health and safety issues for both patients and caregivers. This study examined the characteristics and underlying meaning of hoarding behavior among Taiwanese elders with Alzheimer's dementia from the perspective of family caregivers. We used an exploratory research design and purposive sampling. A total of 12 family caregivers of elders with Alzheimer's dementia received qualitative interview. We used one-on-one in-depth interviews to collect data and content analysis to analyze data. Three main characteristics related to hoarding behavior emerged from the data were "influence of former and current symptoms," "recurrence of the original personal characteristics and habits," and "re-experiencing past economic crises." These three characteristics reflected patients' past social and family background and the current life situation. We elicited "a desire for security" as the underlying meaning of hoarding behavior. Findings of this study provide a reference for family and professional care providers to understand dementia-related problem behaviors. Improved caregiver understanding of dementia patient behaviors may help improve caregiver-patient interaction and communication and help caregivers better meet patient needs.

    Compulsive buying has been associated with addiction, depression, and obsessive-compulsive disorder, as well as hoarding. The present study investigated the relationship that compulsive buying (CB) has with 'addictive' (i.e., sensitivity to reward), obsessive-compulsive, and depressive phenomena, after controlling for hoarding, substance dependence, manic, and Borderline Personality Disorder symptoms. 87 participants from a community population completed the online questionnaires for the study, however 70 participants (M=29.19, SD=10.45; 70% were female) were used in the analyses because of exclusion criteria. As expected, CB measures correlated with hoarding, depression, sensitivity to reward, and, but less so, obsessive-compulsive measures. Sensitivity to reward was the most important predictor of CB severity, compared to obsessive-compulsive and depression symptoms. Hoarding was also an important predictor of CB severity. Small sample size meant gender comparisons could not be made, and the use of a novel, communicated questionnaire meant that interpretation should be considered conservatively. Overall, findings suggest that CB may be most closely related to the phenomena associated with addiction (an increased sensitivity to reward), rather than obsessive-compulsive or depression symptoms. Hoarding and reward sensitivity perhaps might separate compulsive buying from ordinary and recreational shopping. Copyright © 2014 Elsevier Inc. All rights reserved.

    The aim of the present study was to provide preliminary data on the efficacy of a new cognitive-behavioral treatment (CBT) for compulsive hoarding. Fourteen adults with compulsive hoarding (10 treatment completers) were seen in two specialty CBT clinics. Participants were included if they met research criteria for compulsive hoarding according to a semistructured interview, were age 18 or above, considered hoarding their main psychiatric problem, and were not receiving mental health treatment. Patients received 26 individual sessions of CBT, including frequent home visits, over a 7-12 month period between December 2003-February 2005. Primary outcome measures were the Saving Inventory-Revised (SI-R), Clutter Image Rating (CIR), and Clinician's Global Impression (CGI). Significant decreases from pre- to post-treatment were noted on the SI-R and CIR, but not the CGI-severity rating. CGI-Improvement ratings indicated that at mid-treatment, 40% (n=4) of treatment completers were rated "much improved" or "very much improved;" at post-treatment, 50% (n=5) received this rating. Adherence to homework assignments was strongly related to symptom improvement. CBT with specialized components to address problems with motivation, organizing, acquiring and removing clutter appears to be a promising intervention for compulsive hoarding, a condition traditionally thought to be resistant to treatment.

    2014-03-01

    Full Text Available Compulsive hoarders feel emotional attachments to their money and possessions, making it difficult for them to spend or discard accumulated items. Traditionally, hoarding has been seen as a symptom of Obsessive Compulsive Disorder (OCD or Obsessive Compulsive Personality Disorder (OCPD. However, hoarding behavior can be a problem in its own right, without someone meeting the diagnostic criteria for OCD or OCPD. Despite being a mental health disorder that poses a serious public health problem, social costs to the public, and strain on families, there is little empirical work that has examined Hoarding Disorder (HD from a financial perspective. As with other money disorders, for the compulsive hoarder, financial health and mental health symptoms are intertwined. This paper explores the financial psychology of HD and its implications for personal financial planning.

    Many animals regularly hoard food for future use, which appears to be an important adaptation to a seasonally and/or unpredictably changing environment. This food-hoarding paradigm is an excellent example of a natural system that has broadly influenced both theoretical and empirical work in the field of biology. The food-hoarding paradigm has played a major role in the conceptual framework of numerous fields from ecology (e.g. plant-animal interactions) and evolution (e.g. the coevolution of caching, spatial memory and the hippocampus) to psychology (e.g. memory and cognition) and neurobiology (e.g. neurogenesis and the neurobiology of learning and memory). Many food-hoarding animals retrieve caches by using spatial memory. This memory-based behavioural system has the inherent advantage of being tractable for study in both the field and laboratory and has been shaped by natural selection, which produces variation with strong fitness consequences in a variety of taxa. Thus, food hoarding is an excellent model for a highly integrative approach to understanding numerous questions across a variety of disciplines. Recently, there has been a surge of interest in the complexity of animal cognition such as future planning and episodic-like-memory as well as in the relationship between memory, the environment and the brain. In addition, new breakthroughs in neurobiology have enhanced our ability to address the mechanisms underlying these behaviours. Consequently, the field is necessarily becoming more integrative by assessing behavioural questions in the context of natural ecological systems and by addressing mechanisms through neurobiology and psychology, but, importantly, within an evolutionary and ecological framework. In this issue, we aim to bring together a series of papers providing a modern synthesis of ecology, psychology, physiology and neurobiology and identifying new directions and developments in the use of food-hoarding animals as a model system.

    Davis, M.

    The Abergavenny Hoard is a recently discovered collection of late Saxon and Norman silver coins, the details of which were badly obscured by corrosion products and iron concretions. A Q-switched Nd:YAG laser, using near infrared radiation at 1,064 nm, was employed to clean the hoard. Detail retained on the surface of the coins after laser cleaning included "rough-out" marks and polishing marks from the original die, as well as the legend. From this evidence surface damage appears to have been minimal, and the treatment very successful.

    Researchers and clinical practitioners have found that hoarding appears in many autism patients and that most of these patients show high anxiety and depression. There is no consensus on the relationship between autistic traits and hoarding, and little research concerning the role of negative emotions. This study investigated the relationship between autistic traits and hoarding in a large non-clinical Chinese sample. Participants were 3,229 university students (M age = 20.5 yr., SD = 1.6; 1,839 men) who were recruited in classroom. They completed measures of hoarding, autistic symptomology, anxiety, and depression: specifically the Saving Inventory-Revised, the Autism-Spectrum Quotient, the Zung Self-Rating Anxiety Scale, and The Center for Epidemiological Studies Depression Scale. Mediating effects of anxiety and depression in the correlation between autistic traits and hoarding were also explored. There was a weak but significant correlation between autistic traits and hoarding. Significant mediating effects of anxiety and depression were observed. Hoarding in people with high autistic traits could be influenced by anxiety and depression.

    The current investigation utilized mid-life and late-life participants diagnosed with hoarding disorder (HD) to explore the relationship between executive functioning and hoarding severity. Correlational analyses were used to investigate the associations between executive functioning and hoarding severity in nondemented participants. Multiple regression was used to determine if executive functioning had a unique association with HD severity when accounting for depressive symptoms. Participants were recruited from the San Diego area for HD intervention studies. Participants were 113 nondemented adults aged 50-86 years who met DSM-5 criteria for HD. The mean age of the sample utilized in the analyses was 63.76 years (SD, 7.2; range, 51-85 years). The sample was mostly female (72%), Caucasian (81.4%), and unmarried (78%). Hoarding severity was assessed using the Saving Inventory-Revised and the Clutter Image Rating and depression was assessed using the Hospital Anxiety and Depression Scale. Executive functioning was assessed using the Wisconsin Card Sorting Test (WCST-128) and the Trail Making and Verbal Fluency subtests of the Delis-Kaplan Executive Function System. Executive function (operationalized as perseveration on the WCST-128) was significantly associated with Clutter Image Ratings. In a multivariate context, executive function and depressive symptom severity were both significant predictors of variance in Clutter Image Rating. Our results suggest that executive function is related to severity of HD symptoms and should be considered as part of the conceptualization of HD. Published by Elsevier Inc.

    2011-12-01

    The DSM-5 Obsessive-Compulsive Spectrum Sub-Workgroup is recommending the creation of a new diagnostic category named Hoarding Disorder (HD). The validity and acceptability of the proposed diagnostic criteria have yet to be formally tested. Obsessive-compulsive disorder/hoarding experts and random members of the American Psychiatric Association (APA) were shown eight brief clinical vignettes (four cases meeting criteria for HD, three with hoarding behaviour secondary to other mental disorders, and one with subclinical hoarding behaviour) and asked to decide the most appropriate diagnosis in each case. Participants were also asked about the perceived acceptability of the criteria and whether they supported the inclusion of HD in the main manual. Altogether, 211 experts and 48 APA members completed the survey (30% and 10% response rates, respectively). The sensitivity and specificity of the HD diagnosis and the individual criteria were high (80-90%) across various types of professionals, irrespective of their experience with hoarding cases. About 90% of participants in both samples thought the criteria would be very/somewhat acceptable for professionals and sufferers. Most experts (70%) supported the inclusion of HD in the main manual, whereas only 50% of the APA members did. The proposed criteria for HD have high sensitivity and specificity. The criteria are also deemed acceptable for professionals and sufferers alike. Training of professionals and the development and validation of semi-structured diagnostic instruments should improve diagnostic accuracy even further. A field trial is now needed to confirm these encouraging findings with real patients in real clinical settings.

  20. Cholecystokinin-33 acutely attenuates food foraging, hoarding and intake in Siberian hamsters.

    2010-04-01

    Neurochemicals that stimulate food foraging and hoarding in Siberian hamsters are becoming more apparent, but we do not know if cessation of these behaviors is due to waning of excitatory stimuli and/or the advent of inhibitory factors. Cholecystokinin (CCK) may be such an inhibitory factor as it is the prototypic gastrointestinal satiety peptide and is physiologically important in decreasing food intake in several species including Siberian hamsters. Systemic injection of CCK-33 in laboratory rats decreases food intake, doing so to a greater extent than CCK-8. We found minimal effects of CCK-8 on food foraging and hoarding previously in Siberian hamsters, but have not tested CCK-33. Therefore, we asked: Does CCK-33 decrease normal levels or food deprivation-induced increases in food foraging, hoarding and intake? Hamsters were housed in a wheel running-based foraging system with simulated burrows to test the effects of peripheral injections of CCK-33 (13.2, 26.4, or 52.8 microg/kg body mass), with or without a preceding 56 h food deprivation. The highest dose of CCK-33 caused large baseline reductions in all three behaviors for the 1st hour post-injection compared with saline; in addition, the intermediate CCK-33 dose was sufficient to curtail food intake and foraging during the 1st hour. In food-deprived hamsters, we used a 52.8 microg/kg body mass dose of CCK-33 which decreased food intake, hoarding, and foraging almost completely compared with saline controls for 1h. Therefore, CCK-33 appears to be a potent inhibitor of food intake, hoarding, and foraging in Siberian hamsters. Copyright (c) 2009 Elsevier Inc. All rights reserved.

    Full Text Available The focus of this paper is the ornament hoard from the Sopot culture site of Čepin-Ovčara in eastern Slavonia (the Republic of Croatia. The hoard contained pendants and beads made of shells of marine clam Spondylus gaederopus and scaphopod Antalis vulgaris. The paper analyses the context and use wear of the objects in the hoard. The results form a basis for: the reconstruction of the role of some of the items and the ways in which they were worn; the premise that the dynamics and mechanisms of acquisition of ornaments made of the two Mediterranean mollusc species could have differed; and the identification of a cross-cultural pattern of deposition of ornament hoards.

    2009-01-01

    Pathologic hoarding is a symptom generally recognized as related to obsessional dynamics (Gutheil, 1959). The hoarder cannot, without great anxiety, tolerate separation from or dispose of his possessions. Thus the hoarder accumulates vast amount of possessions, often in such amounts as to compromise freedom of movement in the residence. Popular in tabloid reportage, such news items portray persons found dead among floor-to-ceiling piles of old newspapers and similar detritus, while in actual clinical practice such dramatic cases are not common (Bryk, 2005; Duenwald, 2004). More importantly, such individuals are rarely available for psychological intervention or testing, both because of social isolation and injury or death caused by the hoarded materials. Additionally, a majority of the current literature regarding hoarding is linked with Obsessive Compulsive Disorder (OCD), though other major disorders have been noted. This report describes a particular individual with characteristic features of hoarding, which is explored through formal psychological testing.

    The feeding behavior of the deer mouse, Peromyscus maniculatus, includes food hoarding as well as ingestion. Administration of the prototypical mu opiate agonist, morphine sulfate, 1-20 mg/kg, produced over three hours a significant dose-dependent stimulation of hoarding by free feeding deer mice. The specific kappa opiate agonist, U-50,488H, 0.10-10 mg/kg, markedly increased ingestion without having any augmentatory effects on hoarding. The mixed mu and kappa opiate agonist, ketocyclazocine hydrochloride, 1-10 mg/kg, as well as various combinations of morphine sulfate and U-50,488H, augmented both hoarding and ingestion. Food restriction for 24 hr caused a significant, naloxone (1.0 mg/kg) reversible, increase in food intake. Food deprivation also modified the hoarding and ingestion responses of the deer mice to the mu and kappa opiate agonists, reducing the relative amounts of food that were hoarded. These results indicate that mu and kappa opioid systems are differentially involved in the mediation of various aspects of feeding. This also suggests that environmental factors, such as food restriction, can modify the relative roles of mu and kappa opioid systems in the expression of feeding behavior.

    Full Text Available Evidence from silver hoards found in Phoenicia is linking Tarshish, the legendary source of King Solomon's silver, to ores in the western Mediterranean. Biblical passages sometimes describe this lost land as a supplier of metals (especially silver to Phoenician sailors who traded in the service of Solomon and Hiram of Tyre in the 10th century BC. Classical authors similarly attribute the mercantile supremacy of the Phoenicians to their command of lucrative supplies of silver in the west, before they colonised the coasts and islands of its metalliferous regions around 800 BC. Conservative rejections of such reports have correctly emphasised a lack of evidence from silver. Lead isotope analyses of silver hoards found in Phoenicia now provide the initial evidence for pre-colonial silver-trade with the west; ore-provenance data correlate with the ancient documents that indicate both Sardinia and Spain as suppliers, and Sardinia as the island of Tarshish.

    2015-01-01

    A growing number of studies have highlighted impairments in the ability of individuals with autism spectrum disorders to recall specific, personally experienced material. These difficulties have been related to underlying problems with autonoetic consciousness, namely the subjective awareness of one's own existence in subjective time. The current paper describes the manifestation of these difficulties in three individuals diagnosed with Asperger syndrome. For the people described, lifelong collecting and hoarding behaviours appeared to serve the function of constituting and maintaining aspects of their sense of self, particularly the sense of continuity and agency over time. On the basis of this clinical information and previous research into self-related processes in people with autism spectrum disorders, an initial model of collecting and hoarding behaviours amongst individuals with Asperger syndrome was formulated. The implications of this formulation for both clinical practice and future research are discussed. People with Asperger syndrome can have problems in developing a functional sense of self. Collecting and hoarding behaviour by people with Asperger syndrome may reflect such underlying difficulties in their sense of self rather than being symptoms of comorbid mental illness. Interventions need to take account of the function of such behaviours rather than solely regarding them as discrete pathological signs. Copyright © 2014 John Wiley & Sons, Ltd.

    Scatter hoarding of seeds by animals contributes significantly to forest-level processes, including plant recruitment and forest community composition. However, the potential positive and negative effects of caching on seed survival, germination success, and seedling survival have rarely been assessed through experimental studies. Here, I tested the hypothesis that seed burial mimicking caches made by scatter hoarding Central American agoutis (Dasyprocta punctate) enhances seed survival, germination, and growth by protecting seeds from seed predators and providing favorable microhabitats for germination. In a series of experiments, I used simulated agouti seed caches to assess how hoarding affects seed predation by ground-dwelling invertebrates and vertebrates for four plant species. I tracked germination and seedling growth of intact and beetle-infested seeds and, using exclosures, monitored the effects of mammals on seedling survival through time. All experiments were conducted over three years in a lowland wet forest in Costa Rica. The majority of hoarded palm seeds escaped predation by both invertebrates and vertebrates while exposed seeds suffered high levels of infestation and removal. Hoarding had no effect on infestation rates of D. panamensis, but burial negatively affected germination success by preventing endocarp dehiscence. Non-infested palm seeds had higher germination success and produced larger seedlings than infested seeds. Seedlings of A. alatum and I. deltoidea suffered high mortality by seed-eating mammals. Hoarding protected most seeds from predators and enhanced germination success (except for D. panamensis) and seedling growth, although mammals killed many seedlings of two plant species; all seedling deaths were due to seed removal from the plant base. Using experimental caches, this study shows that scatter hoarding is beneficial to most seeds and may positively affect plant propagation in tropical forests, although tradeoffs in seed

    2014-07-01

    OBJECT.: Recent findings have suggested a correlation between obsessive-compulsive disorder (OCD) symptom dimensions and clinical outcome after limbic system surgery for treatment-refractory patients. Based on previous evidence that the hoarding dimension is associated with worse outcome in conventional treatments, and may have a neural substrate distinct from OCD, the authors examined a large sample of patients undergoing limbic surgery (40 with capsulotomy, 37 with cingulotomy) and investigated if symptom dimensions, in particular hoarding, could influence treatment outcome. Data from 77 patients from 3 different research centers at São Paulo (n = 17), Boston (n = 37), and Stockholm (n = 23) were analyzed. Dimensional Yale-Brown Obsessive Compulsive Scale (Y-BOCS; São Paulo) or Y-BOCS Symptom Checklist scores (Boston and Stockholm) were used to code the presence of 4 well-established symptom dimensions: forbidden thoughts, contamination/cleaning, symmetry/order, and hoarding. Reductions in YBOCS scores determined clinical outcome. Mean Y-BOCS scores decreased 34.2% after surgery (95% CI 27.2%-41.3%), with a mean follow-up of 68.1 months. Patients with hoarding symptoms had a worse response to treatment (mean Y-BOCS decrease of 22.7% ± 25.9% vs 41.6% ± 32.2%, respectively; p = 0.006), with no significant effect of surgical modality (capsulotomy vs cingulotomy). Patients with forbidden thoughts apparently also had a worse response to treatment, but this effect was dependent upon the co-occurrence of the hoarding dimension. Only the negative influence of the hoarding dimension remained when an ANOVA model was performed, which also controlled for preoperative symptom severity. The presence of hoarding symptoms prior to surgery was associated with worse clinical outcome after the interventions. Patients with OCD under consideration for ablative surgery should be carefully screened for hoarding symptoms or comorbid hoarding disorder. For these patients, the

  15. Seed removal by scatter-hoarding rodents: the effects of tannin and nutrient concentration.

    Science.gov (United States)

    Wang, Bo; Yang, Xiaolan

    2015-04-01

    The mutualistic interaction between scatter-hoarding rodents and seed plants have a long co-evolutionary history. Plants are believed to have evolved traits that influence the foraging behavior of rodents, thus increasing the probability of seed removal and caching, which benefits the establishment of seedlings. Tannin and nutrient content in seeds are considered among the most essential factors in this plant-animal interaction. However, most previous studies used different species of plant seeds, rendering it difficult to tease apart the relative effect of each single nutrient on rodent foraging behavior due to confounding combinations of nutrient contents across seed species. Hence, to further explore how tannin and different nutritional traits of seed affect scatter-hoarding rodent foraging preferences, we manipulated tannin, fat, protein and starch content levels, and also seed size levels by using an artificial seed system. Our results showed that both tannin and various nutrients significantly affected rodent foraging preferences, but were also strongly affected by seed size. In general, rodents preferred to remove seeds with less tannin. Fat addition could counteract the negative effect of tannin on seed removal by rodents, while the effect of protein addition was weaker. Starch by itself had no effect, but it interacted with tannin in a complex way. Our findings shed light on the effects of tannin and nutrient content on seed removal by scatter-hoarding rodents. We therefore, believe that these and perhaps other seed traits should interactively influence this important plant-rodent interaction. However, how selection operates on seed traits to counterbalance these competing interests/factors merits further study. Copyright © 2015 Elsevier B.V. All rights reserved.

    2013-01-01

    Clutter impeding the normal use of living spaces is a landmark feature of hoarding disorder (HD) but can also be present in other conditions. The assessment of clutter ideally requires home visits, although such assessments are sometimes not feasible. This study examined whether photographs from patients' homes can assist in the diagnostic process. Thirty-two professionals with experience with hoarding cases were shown pictures from the inside of 10 houses and asked to decide whether the house belonged to a person with HD, a person with obsessive compulsive disorder (OCD), or a healthy collector. Participants also rated different features of the room appearing in each picture (overall amount of possessions, tidiness, functionality, number of different classes of items, and cleanliness). Sensitivity for the HD and collectors' pictures was high, whereas sensitivity for the OCD pictures was substantially lower. Specificity was high for all groups. Rooms belonging to HD individuals were rated as significantly more cluttered, more untidy, less functional, containing a higher number of different classes of items, and being less clean than the rooms from the remaining groups. Photographs may be used to assist clinicians in determining the presence of clinically significant levels of clutter in the event a home visit is not feasible. Although differential diagnosis will usually not be possible from photographs alone, examination of certain characteristics of the environment might provide useful diagnostic clues. Combined with a thorough psychopathological interview, the use of photographs may increase the clinician's confidence in the diagnosis of HD. © 2012 Wiley Periodicals, Inc.

    This study examined psychological processes of consumers that had determined hoarding and avoidant purchasing behaviors after the Tohoku earthquake within a dual-process model. The model hypothesized that both intentional motivation based on reflective decision and reactive motivation based on non-reflective decision predicted the behaviors. This study assumed that attitude, subjective norm and descriptive norm in relation to hoarding and avoidant purchasing were determinants of motivations. Residents in the Tokyo metropolitan area (n = 667) completed internet longitudinal surveys at three times (April, June, and November, 2011). The results indicated that intentional and reactive motivation determined avoidant purchasing behaviors in June; only intentional motivation determined the behaviors in November. Attitude was a main determinant of the motivations each time. Moreover, previous behaviors predicted future behaviors. In conclusion, purchasing behaviors were intentional rather than reactive behaviors. Furthermore, attitude and previous behaviors were important determinants in the dual-process model. Attitude and behaviors formed in April continued to strengthen the subsequent decisions of purchasing behavior.

    2013-12-01

    Full Text Available Two silver dirhams of Khwarezm, dated to 670 AH/1271AD, with an unusual tamga are analyzed in the article. The coins come from a hoard located in the territory of Turkmenistan, the exact place of discovery being unknown. On both coins under consideration, a new, previously unknown type of tamga has been discovered. Typologically, it belongs to the tamgas of the house of Chagatai. A comparison of the dates of the coins with the information about the 1270s events in Khwarezm made it possible to determine that the tamga belonged to Negubei of the house of Chagatai. The finding also confirms that Kaidu (Qaidu, the khan of the Chagataid state, retained the right of the Chagatai Ulus owners to participate in the distribution of income from Khwarezm from the beginning of his reign.

    The elemental composition of 122 silver coins from a hoard of the 3rd century BC, minted by the Illyrian king Monounios and the ancient cities of Dyrrachion and Korkyra was determined by EDXRF. The results showed that the different groups of coins were made of a similar Ag-Cu alloy with Ag concentration in the range 94-98%. The examination of the contents of minor elements Pb, Au and Bi showed that the coins minted by the Illyrian king Monounios have similar composition with the largest part of Dyrrachion coins and those from Korkyra. On the other side, two subgroups containing different amounts of Au and Bi can be observed within the general group of coins minted in Dyrrachion.

    Full Text Available A hoard of pottery, metal lamps, mirrors and a lampad, accidentally discovered on the Uvek settlement site in 1994 is made public. The pottery items are represented by three Qashan pottery bowls with underglaze painting and a red-clay jug. The two bronze lamps demonstrate the nearest analogy to those found on the Tsarev fortified settlement site and belong to the type that was spread in the Golden Horde cities. The copper lampad is a product of Byzantine circle, also common in Russia. The two bronze mirrors were imported from China or were made according to Chinese tradition. The objects bear traces of a fire. The authors have concluded that the assemblage had belonged to a wealthy who resided in the Russian Christian quarter. The items were probably concealed in the 1360s as a result of the tragic events associated with the start of the "Great troubles" in the Golden Horde.

    Full Text Available Most animals can discriminate between pairs of numbers that are each less than four without training. However, North Island robins (Petroica longipes, a food hoarding songbird endemic to New Zealand, can discriminate between quantities of items as high as eight without training. Here we investigate whether robins are capable of other complex quantity discrimination tasks. We test whether their ability to discriminate between small quantities declines with 1. the number of cache sites containing prey rewards and 2. the length of time separating cache creation and retrieval (retention interval. Results showed that subjects generally performed above chance expectations. They were equally able to discriminate between different combinations of prey quantities that were hidden from view in 2, 3 and 4 cache sites from between 1, 10 and 60 seconds. Overall results indicate that North Island robins can process complex quantity information involving more than two discrete quantities of items for up to one minute long retention intervals without training.

    Both as consumers and dispersers of seeds, scatter-hoarding rodents often play an important role in the reproductive ecology of many plant species. However, the seeds of many plant species contain tannins, which are a diverse group of water-soluble phenolic compounds that have a high affinity for proteins. The amount of tannins in seeds is expected to affect rodent foraging preferences because of their major impact on rodent physiology and survival. However, variable results have been obtained in studies that evaluated the effects of tannin on rodent foraging behavior. Hence, in this study, we aimed to explain these inconsistent results and proposed that a combination of seed traits might be important in rodent foraging behavior, because it is difficult to distinguish between the effects of individual traits on rodent foraging behavior and the interactions among them. By using a novel artificial seed system, we manipulated seed tannin and fat/protein levels to examine directly the univariate effects of each component on the seed preferences of free-ranging forest rats (Apodemus latronum and Apodemus chevrieri) during the behavioral process of scatter hoarding. Our results showed that both tannin and fat/protein had significant effects on rodent foraging behavior. Although only a few interactive effects of tannin and fat/protein were recorded, higher concentrations of both fat and protein could attenuate the exclusion of seeds with higher tannin concentrations by rodents, thus influencing seed fate. Furthermore, aside from the concentrations of tannin, fat, and protein, numerous other traits of plant seeds may also influence rodent foraging behavior. We suggest that by clarifying rodent foraging preferences, a better understanding of the evolution of plant seed traits may be obtained because of their strong potential for selective pressure.

    Full Text Available Description of the subject. Quercus rubra L. is considered an invasive species in several European countries. However, little is known about its dispersal in the introduced range. Objectives. We investigated the significance of animal dispersal of Q. rubra acorns on the ground by vertebrates in its introduced range, and identified the animal species involved. Method. During two consecutive autumns, the removal of acorns from Q. rubra and from a native oak was assessed weekly in forest sites in Belgium. We used automated detection camera traps to identify the animals that removed acorns. Results. Quercus rubra acorns were removed by wood mice (Apodemus sylvaticus L., red squirrels (Sciurus vulgaris L., rats (Rattus sp., and wild boars (Sus scrofa L.. The two former are scatter-hoarding rodents and can be considered potential dispersers. Conclusions. Dispersal of Q. rubra acorns in Western Europe by scatter-hoarding animals may help the species increasingly colonize forest ecosystems.

    Utilizing a qualitative approach, the current study explored therapist and patient perspectives on a specialized cognitive-behavioral therapy (CBT) protocol for clinically significant hoarding in older adult patients. Data were derived from the following sources: (1) therapist observation; (2) CBT consultant observation; (3) clinical treatment notes; (4) participant feedback, including a focus group; and (5) participant in-session notes and completed homework assignments. Our findings showed that the value of homework, treatment session compliance, and deficits in executive functioning (prospective memory, planning, problem solving, and cognitive flexibility) were common themes among participants as viewed by the therapist. Patients reported that exposure exercises and the therapeutic relationship were the most helpful aspects of their treatment, while cognitive strategies had limited success. Our results suggest that treatment for hoarding in older adults may be improved by focusing on exposure therapy elements, remediating executive function deficits, providing simplified homework assignments, and decreasing the emphasis or modifying cognitive restructuring techniques.

    Attitudes towards risk are highly consequential in clinical disorders thought to be prone to "risky behavior", such as substance dependence, as well as those commonly associated with excessive risk aversion, such as obsessive-compulsive disorder (OCD) and hoarding disorder (HD). Moreover, it has recently been suggested that attitudes towards risk may serve as a behavioral biomarker for OCD. We investigated the risk preferences of participants with OCD and HD using a novel adaptive task and a quantitative model from behavioral economics that decomposes risk preferences into outcome sensitivity and probability sensitivity. Contrary to expectation, compared to healthy controls, participants with OCD and HD exhibited less outcome sensitivity, implying less risk aversion in the standard economic framework. In addition, risk attitudes were strongly correlated with depression, hoarding, and compulsion scores, while compulsion (hoarding) scores were associated with more (less) "rational" risk preferences. These results demonstrate how fundamental attitudes towards risk relate to specific psychopathology and thereby contribute to our understanding of the cognitive manifestations of mental disorders. In addition, our findings indicate that the conclusion made in recent work that decision making under risk is unaltered in OCD is premature. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Abstract Background Overweight children as young as 5 years old exhibit disturbances in eating behaviors. Methods Using follow-up data from 419 participants in High Five for Kids, a randomized controlled trial of overweight children, the prevalence of (1) eating in the absence of hunger and (2) food sneaking, hiding, and hoarding was estimated and cross-sectional associations of parental control of feeding and these behaviors were examined using covariate-adjusted logistic regression models. Results At follow-up, mean [standard deviation (SD)] age of the children was 7.1 (1.2) years; 49% were female; 16% were healthy weight, 35% were overweight, and 49% were obese. On the basis of parental report, 16.5% of children were eating in the absence of hunger and 27.2% were sneaking, hiding, or hoarding food; 57.5% of parents endorsed parental control of feeding. In adjusted models, children exposed to parental control of feeding were more likely to eat in the absence of hunger [odds ratio (OR) 3.37, 95% confidence interval (CI) 1.66, 6.86], but not to sneak, hide, or hoard food (OR 1.43, 95% CI 0.87, 2.36). Conclusions Disturbances in eating behaviors are common among overweight children. Future research should be dedicated to identifying strategies that normalize eating behaviors and prevent excess weight gain among overweight children. PMID:23806073

  12. The soil carbon dilemma in the humid tropics: cannot hoard it!?

    Sommer, Rolf; Paul, Birthe; Kihara, Job

    2017-04-01

    As Albrecht (1938) wrote some 70 years ago: "[Soil] Organic matter functions mainly as it is decayed and destroyed. Its value lies in its dynamic nature." Thus, by merely hoarding rather than using soil organic matter (SOM; compare also Janzen, 2006) with the aim to sequester carbon (C) in soils, we risk neglecting the crucial aspect that decomposing SOM and the release of nutrients (and concurrently CO2) is the basis for a healthy crop, decent yields and thus food security. This is even more true so in the tropics, where the majority of soils have low intrinsic fertility. In the absence of sufficient nutrient inputs through fertilizers in smallholder subsistence agriculture predominating e.g. in sub-Saharan Africa (SSA), SOM turnover is the key driver of crop productivity. On the other hand, humid tropical conditions - high temperatures and long periods of moist conditions - are very conducive to SOM decay. Therefore, maintaining SOM levels requires the constant input of significant amounts of organic matter; material that is often in low supply while then first of all used as animal feed in SSA mixed-crop livestock systems. In this context it is not surprising that for SSA very few studies so far have been published that showcased viable agronomic management systems that did also sequester notable C in the soil. The two long-term trials of the International Center for Tropical Agriculture (CIAT) in Western Kenya are no exception. Neither Conservation Agriculture (CA) nor Integrated Soil Fertility Management (ISFM) management practices over a period of 12 years could prevent the topsoil from losing C. But, these two practices could significantly slow down C losses in comparison to treatments representing common farmer practice. Also in comparison to the latter, yields of CA and ISFM plots were 2-4 time higher. This example shows that hoarding SOM in soils under humid tropical conditions is a challenge, and to attain amounts required to come even close to the 4p

    Understanding the survival value of behaviour does not tell us how the mechanisms that control this behaviour work. Nevertheless, understanding survival value can guide the study of these mechanisms. In this paper, we apply this principle to understanding the cognitive mechanisms that support cache retrieval in scatter-hoarding animals. We believe it is too simplistic to predict that all scatter-hoarding animals will outperform non-hoarding animals on all tests of spatial memory. Instead, we argue that we should look at the detailed ecology and natural history of each species. This understanding of natural history then allows us to make predictions about which aspects of spatial memory should be better in which species. We use the natural hoarding behaviour of the three best-studied groups of scatter-hoarding animals to make predictions about three aspects of their spatial memory: duration, capacity and spatial resolution, and we test these predictions against the existing literature. Having laid out how ecology and natural history can be used to predict detailed cognitive abilities, we then suggest using this approach to guide the study of the neural basis of these abilities. We believe that this complementary approach will reveal aspects of memory processing that would otherwise be difficult to discover.

    Difficulties in decision making are a core impairment in a range of disease states. For instance, both obsessive- compulsive disorder (OCD) and hoarding disorder (HD) are associated with indecisiveness, inefficient planning, and enhanced uncertainty intolerance, even in contexts unrelated to their core symptomology. We examined decision-making patterns in 19 individuals with OCD, 19 individuals with HD, 19 individuals with comorbid OCD and HD, and 57 individuals from the general population, using a well-validated choice task grounded in behavioral economic theory. Our results suggest that difficulties in decision making in individuals with OCD (with or without comorbid HD) are linked to reduced fidelity of value-based decision making (i.e. increase in inconsistent choices). In contrast, we find that performance of individuals with HD on our laboratory task is largely intact. Overall, these results support our hypothesis that decision-making impairments in OCD and HD, which can appear quite similar clinically, have importantly different underpinnings. Systematic investigation of different aspects of decision making, under varying conditions, may shed new light on commonalities between and distinctions among clinical syndromes. Copyright © 2017.

    The present study evaluated the efficacy of adding a virtual reality (VR) component to the treatment of compulsive hoarding (CH), following inference-based therapy (IBT). Participants were randomly assigned to either an experimental or a control condition. Seven participants received the experimental and seven received the control condition. Five sessions of 1 h were administered weekly. A significant difference indicated that the level of clutter in the bedroom tended to diminish more in the experimental group as compared to the control group F(2,24) = 2.28, p = 0.10. In addition, the results demonstrated that both groups were immersed and present in the environment. The results on posttreatment measures of CH (Saving Inventory revised, Saving Cognition Inventory and Clutter Image Rating scale) demonstrate the efficacy of IBT in terms of symptom reduction. Overall, these results suggest that the creation of a virtual environment may be effective in the treatment of CH by helping the compulsive hoarders take action over their clutter.

    Full Text Available This paper presents the results of scientific examinations and analyses carried out on the archaeological coins discovered in Najran, Saudi Arabia. Optical microscopy (OM, scanning electron microscopy (SEM coupled with energy dispersive spectrometry (EDS and X-ray diffraction (XRD were used to investigate morphological corrosion features, to clear the nature of the patina and to analyze the elementary composition. Morphologically, it was revealed that there are reniform, coral reef and dendritic shapes of corrosion products and heterogeneous multicolor patina on the studied coin surfaces. It was proven that those coins were made of a silver-copper alloy and were covered by three superficial corrosion layers. The main composition of the coin corrosion compounds was identified as copper carbonate, copper chloride, copper silicates, silver chlorides and silver sulphide. The proposed corrosion mechanism revealed that those coins were characterized by heavy degradation phenomena, induced by corrosive species and soil contaminants. The corrosion processes led to the depletion of the copper and silver enrichment near the surface, as compared to the core composition. This study provides useful information for the conservation and preservation of the Najran hoard coins.

  3. Fruit Size Determines the Role of Three Scatter-Hoarding Rodents as Dispersers or Seed Predators of a Fleshy-Fruited Atacama Desert Shrub

    Loayza, Andrea P.; Squeo, Francisco A.

    2016-01-01

    Scatter-hoarding rodents can act as both predators and dispersers for many large-seeded plants because they cache seeds for future use, but occasionally forget them in sites with high survival and establishment probabilities. The most important fruit or seed trait influencing rodent foraging behavior is seed size; rodents prefer large seeds because they have higher nutritional content, but this preference can be counterbalanced by the higher costs of handling larger seeds. We designed a cafeteria experiment to assess whether fruit and seed size of Myrcianthes coquimbensis, an endangered desert shrub, influence the decision-making process during foraging by three species of scatter-hoarding rodents differing in body size: Abrothrix olivaceus, Phyllotis darwini and Octodon degus. We found that the size of fruits and seeds influenced foraging behavior in the three rodent species; the probability of a fruit being harvested and hoarded was higher for larger fruits than for smaller ones. Patterns of fruit size preference were not affected by rodent size; all species were able to hoard fruits within the entire range of sizes offered. Finally, fruit and seed size had no effect on the probability of seed predation, rodents typically ate only the fleshy pulp of the fruits offered and discarded whole, intact seeds. In conclusion, our results reveal that larger M. coquimbensis fruits have higher probabilities of being harvested, and ultimately of its seeds being hoarded and dispersed by scatter-hoarding rodents. As this plant has no other dispersers, rodents play an important role in its recruitment dynamics. PMID:27861550

These symptoms include excessive acquisition, difficulty in discarding, and excessive clutter that causes distress. We conducted three studies to examine the factor structure, reliability, and validity of the Japanese version of the HRS-SR (HRS-SR-J. Methods: Study 1 examined its reliability; 193 college students and 320 adolescents and adults completed the HRS-SR-J and, of the college students, 32 took it again 2 weeks later. Study 2 aimed to confirm that its scores in a sample of 210 adolescents and adults are independent of social desirability. Study 3 aimed to validate the HRS-SR-J in the aspects of convergent and discriminant validity in a sample of 550 adults. Results: The HRS-SR-J showed good internal consistency and 2-week test–retest reliability. Based on the nonsignificant correlations between the HRS-SR-J and social desirability, the HRS-SR-J was not strongly affected by social desirability. In addition, it also had a good convergent validity with the Japanese version of the Saving Inventory-Revised (SI-R-J and the hoarding subscale of the Obsessive-Compulsive Inventory, while having a significantly weaker correlation with the five subscales of the Obsessive-Compulsive Inventory, except for the hoarding subscale.

    Optic ataxia (OA) is classically defined as a deficit of visually guided movements that follows lesions of the posterior part of the posterior parietal cortex (PPC). Since the formalisation of the double stream of visual information processing [Milner, A. D., & Goodale, M. A. (1995). The visual brain in action. Oxford: Oxford University Press] and the use of OA as an argument in favour of the involvement of the posterior parietal cortex (dorsal stream) in visually guided movements, many studies have looked at the visuomotor deficits of these patients. In parallel, the development of neuroimaging methods have led to increasing information about the role of the posterior parietal cortex in visually guided actions. In this article, we discuss the similarities and differences in the results that emerged from these two complementary viewpoints by combining a meta-analysis of neuroimaging data on reaching with lesion studies from OA patients and results of our own fMRI study on reaching in the ipsi- and contra-lateral visual field. We identified four bilateral parietal foci from the meta-analysis and found that the more posterior foci showed greater lateralisation for contralateral visual stimulation than more anterior ones Additionally, the more anterior foci showed greater lateralisation for the use of the contralateral hand than the more posterior ones. Therefore, we can demonstrate that they are organised along a postero-anterior gradient of visual-to-somatic information integration. Furthermore, from the combination of imaging and lesion data it can be inferred that a lesion of the three most posterior foci responsible for the target-hand integration could explain the hand and field effect revealed in OA reaching behaviour.

    Many animals hoard seeds for later consumption and establish seed caches that are often located at sites with specific environmental characteristics. One explanation for the selection of non-random caching locations is the avoidance of pilferage by other animals. Another possible hypothesis is that animals choose locations that hamper the perishability of stored food, allowing the consumption of unspoiled food items over long time periods. We examined seed perishability and pilferage avoidance as potential drivers for caching behaviour of spotted nutcrackers (Nucifraga caryocatactes) in the Swiss Alps where the birds are specialized on caching seeds of Swiss stone pine (Pinus cembra). We used seedling establishment as an inverse measure of seed perishability, as established seedlings cannot longer be consumed by nutcrackers. We recorded the environmental conditions (i.e. canopy openness and soil moisture) of seed caching, seedling establishment and pilferage sites. Our results show that sites of seed caching and seedling establishment had opposed microenvironmental conditions. Canopy openness and soil moisture were negatively related to seed caching but positively related to seedling establishment, i.e. nutcrackers cached seeds preferentially at sites where seed perishability was low. We found no effects of environmental factors on cache pilferage, i.e. neither canopy openness nor soil moisture had significant effects on pilferage rates. We thus could not relate caching behaviour to pilferage avoidance. Our study highlights the importance of seed perishability as a mechanism for seed-caching behaviour, which should be considered in future studies. Our findings could have important implications for the regeneration of plants whose seeds are dispersed by seed-caching animals, as the potential of seedlings to establish may strongly decrease if animals cache seeds at sites that favour seed perishability rather than seedling establishment. © 2014 The Authors.

    Hoarding disorder (HD) places an important burden on people with HD, on their family members and society. In this paper we evaluate help-seeking in HD at primary mental health, measured in referral rate, together with its individual, environmental and structural correlates. We conducted an aggregate study by combining existing official data with our own survey data at the catchment area level. We found a mean annual referral rate of 1.58 (SD = 1.79) cases of HD in primary mental health facilities per 10,000 of adult population. The referrals rate correlated with socio-demographic characteristics of the catchment area, the availability of tools for clinical management of HD, and affiliation to a University Medical school. We also found that: (1) family members, neighbours, municipal workers and health professionals are the primary source of complaints for HD; (2) 72% of primary mental health facilities worked with HD in crisis situations, 52% expressed difficulties in obtaining the consent of people with HD for an intervention (3) health/social services professionals lack HD clinical management tools, training and formal collaboration with municipal (housing, building security, fire prevention) specialists. Improvement of the readiness of the health-system to deal with HD will improve help-seeking for formal medical counselling on the part of people with HD. We can improve this readiness by providing primary mental-health facilities with training, clinical management tools and by helping them to establish formal collaboration with municipalities and community organisations. University medical schools can take a leadership role and become centers catalysing the change in HD clinical management.

    Co-varying traits in acorns such as seed size and germination schedule are important to influence the behavioural decisions of hoarding rodents. Using acorn pairs from cork oak (Quercus variabilis) (large size and short germination schedules) serrate oak (Q. serrata) (small size and short germination schedule) and qinggang (Cyclobalanopsis glauca) (small size and long germination schedule) with contrasting seed size and germination schedule, we conducted a series of experiments to investigate hoarding preferences in response to seed size and germination schedule by Edward's long-tailed rats (Leopoldamys edwardsi) and South China field mice (Apodemus draco) in semi-natural enclosures. We found that the seed size hypothesis was consistently supported: both rodent species ate more small acorns but hoarded more large ones regardless of germination schedules. However, the germination schedule hypothesis was also supported when similar sized acorns were simultaneously provided, e.g. Q. serrata versus C. glauca or germinating versus non-germinating Q. variabilis. Our results, contrary to the studies from North America, indicate that seed size is more important than germination schedules in determining whether the tested animals eat or hoard a given seed.

    Strawbridge Observatory at Haverford College is home to a undergraduate-led public observing program. Our program holds ~once monthly public events throughout the academic year that take advantage of eyepiece observing on our 16-inch and 12-inch telescopes as well as of the classroom, library, and projection system. These resources allow us to organize a variety of astronomy related activities that are engaging for individuals of all ages: accessible student talks, current film screenings and even arts and crafts for the families who attend with young children. These events aim to spark curiosity in others about scientific discovery and about the remarkable nature of the world in which we live. In addition to exciting local families about astronomy, this program has excited Haverford students from a range of disciplines about both science and education. Being entirely student led means that we are able to take the initiative in planning, coordinating and running all events, fostering an atmosphere of collaboration, experimentation and commitment amongst our volunteers. Additionally, this program is one of the few at Haverford that regularly reaches beyond the campus walls to promote and build relationships with the outside community. In light of this, our program presents a distinctive and enlightening opportunity for student volunteers: we get to use our scientific backgrounds to educate a general audience, while also learning from them about how to communicate and inspire in others the excitement we feel about the subject of astronomy. The work on this project has been supported by NSF AST-1151462.

  12. UX-15 Reaches LEP

    2001-01-01

    The creation of the world's largest sandstone cavern, not a small feat! At the bottom, cave-in preventing steel mesh can be seen clinging to the top of the tunnel. The digging of UX-15, the cavern that will house ATLAS, reached the upper ceiling of LEP on October 10th. The breakthrough which took place nearly 100 metres underground occurred precisely on schedule and exactly as planned. But much caution was taken beforehand to make the LEP breakthrough clean and safe. To prevent the possibility of cave-ins in the side tunnels that will eventually be attached to the completed UX-15 cavern, reinforcing steel mesh was fixed into the walls with bolts. Obviously no people were allowed in the LEP tunnels below UX-15 as the breakthrough occurred. The area was completely evacuated and fences were put into place to keep all personnel out. However, while personnel were being kept out of the tunnels below, this has been anything but the case for the work taking place up above. With the creation of the world's largest...

    Growing awareness of health and health care disparities highlights the importance of including information about race, ethnicity, and culture (REC) in health research. Reporting of REC factors in research publications, however, is notoriously imprecise and unsystematic. This article describes the development of a checklist to assess the comprehensiveness and the applicability of REC factor reporting in psychiatric research publications. The 16-itemGAP-REACH© checklist was developed through a rigorous process of expert consensus, empirical content analysis in a sample of publications (N = 1205), and interrater reliability (IRR) assessment (N = 30). The items assess each section in the conventional structure of a health research article. Data from the assessment may be considered on an item-by-item basis or as a total score ranging from 0% to 100%. The final checklist has excellent IRR (κ = 0.91). The GAP-REACH may be used by multiple research stakeholders to assess the scope of REC reporting in a research article. PMID:24080673

    The Hoarding Rating Scale-Self-Report (HRS-SR) is a five-item scale that assesses the symptoms of hoarding. These symptoms include excessive acquisition, difficulty in discarding, and excessive clutter that causes distress. We conducted three studies to examine the factor structure, reliability, and validity of the Japanese version of the HRS-SR (HRS-SR-J). Study 1 examined its reliability; 193 college students and 320 adolescents and adults completed the HRS-SR-J and, of the college students, 32 took it again 2 weeks later. Study 2 aimed to confirm that its scores in a sample of 210 adolescents and adults are independent of social desirability. Study 3 aimed to validate the HRS-SR-J in the aspects of convergent and discriminant validity in a sample of 550 adults. The HRS-SR-J showed good internal consistency and 2-week test-retest reliability. Based on the nonsignificant correlations between the HRS-SR-J and social desirability, the HRS-SR-J was not strongly affected by social desirability. In addition, it also had a good convergent validity with the Japanese version of the Saving Inventory-Revised (SI-R-J) and the hoarding subscale of the Obsessive-Compulsive Inventory, while having a significantly weaker correlation with the five subscales of the Obsessive-Compulsive Inventory, except for the hoarding subscale. In addition, the strength of the correlation between the HRS-SR-J and the Japanese version of the Patient Health Questionnaire-9 and that between the HRS-SR-J and the Generalized Anxiety Disorder-7 were significantly weaker than the correlation between the HRS-SR-J and the SI-R-J. These results demonstrate that the HRS-SR-J has good convergent and discriminant validity. The HRS-SR-J is a notable self-report scale for examining the severity of hoarding symptoms.

    Five fragments of ancient gold objects belonging to Pietroasa 'Closca cu Puii de Aur' ('The Golden Brood Hen with Its Chickens') Romanian hoard were analysed using the micro-PIXE (particle induced X-ray emission) technique. The purpose of the study was to gain some more knowledge regarding the metal provenance by determining the presence of PGE (Platinum Group Elements) and other high-temperature melting point trace elements (Ta, Nb, Cr) at a micrometric scale. Ta and Nb inclusions (micrometric areas of composition different from the surroundings) on three samples and Pd inclusions on one sample were found. The measurements led to some conclusions for the possible gold ore sources of Pietroasa treasury: the South-Ural Mountains, Nubia (Sudan) and/or Anatolian deposits and Roman imperial coins.

    Background Addictive-like behaviors (e.g., hoarding and shopping) may be the result of the cumulative effects of dopaminergic and other neurotransmitter genetic variants as well as elevated stress levels. We, therefore, propose that dopamine homeostasis may be the preferred goal in combating such challenging and unwanted behaviors, when simple dopaminergic activation through potent agonists may not provide any resolution. Case presentation C.J. is a 38-year-old, single, female, living with her mother. She has a history of substance use disorder as well as attention deficit hyperactivity disorder, inattentive type. She had been stable on buprenorphine/naloxone combination and amphetamine, dextroamphetamine mixed salts for many years when unexpectedly she lost her job for oversleeping and not calling into work. KB200z (a pro-dopamine compound) was added to her regimen for complaints of low drive and motivation. After taking this nutraceutical for 4 weeks, she noticed a marked improvement in her mental status and many behaviors. She noted that her shopping and hoarding addictions had appreciably decreased. Furthermore, her lifelong history of terrifying lucid dreams was eliminated. Finally, she felt more in control; her locus of control shifted from external to more internal. Discussion The hypothesis is that C.J.'s reported, behavioral, and psychological benefits resulted from the pro-dopamine-regulating effect of KB220Z across the brain reward system. Conclusions This effect, we surmise, could be the result of a new dopamine balance, across C.J.'s brain reward system. Dopamine homeostasis is an effect of KB220Z seen in both animal and human placebo-controlled fMRI experiments.

  18. No evidence for memory interference across sessions in food hoarding marsh tits Poecile palustris under laboratory conditions.

    Scatter hoarding birds are known for their accurate spatial memory. In a previous experiment, we tested the retrieval accuracy in marsh tits in a typical laboratory set-up for this species. We also tested the performance of humans in this experimental set-up. Somewhat unexpectedly, humans performed much better than marsh tits. In the first five attempts, humans relocated almost 90 % of the caches they had hidden 5 h earlier. Marsh tits only relocated 25 % in the first five attempts and just above 40 % in the first ten attempts. Typically, in this type of experiment, the birds will be caching and retrieving many times in the same sites in the same experimental room. This is very different from the conditions in nature where hoarding parids only cache once in a caching site. Hence, it is possible that memories from previous sessions will disturb the formation of new memories. If there is such proactive interference, the prediction is that success should decay over sessions. Here, we have designed an experiment to investigate whether there is such memory interference in this type of experiment. We allowed marsh tits and humans to cache and retrieve in three repeated sessions without prior experience of the arena. The performance did not change over sessions, and on average, marsh tits correctly visited around 25 % of the caches in the first five attempts. The corresponding success in humans was constant across sessions, and it was around 90 % on average. We conclude that the somewhat poor performance of the marsh tits did not depend on proactive memory interference. We also discuss other possible reasons for why marsh tits in general do not perform better in laboratory experiments.

    Conclusion: Emotional distancing occurs during these reflective activities, which seems to play an important role when utilising the “HOARD” acronym tool. Three key themes emerged from the data: The evocative power of the image, Images as monitoring tools and verifying and validating the hoarding problem. This particular methodological approach is beneficial in generating valuable narrative for self-reflection. [JCBPR 2013; 2(1.000: 41-46

    Full Text Available The conformity of education, including that of university, or tertiary education, to employers' expectations represents one aspect of society's expectations towards the whole education system. There is given an overview of the changes of personal expectations to university education and of the requirements to highly educated professionals. Educational policies are shaped under the influence of both of these subjects and find their outcome in universities curricula. It is important to quantify employers' valuations of university curricula on the level of particular learning outcomes and skills, based on which it is possible to make conclusions for implementing them in curricula. A research of master degree pedagogical curricula that was conducted in Narva College of Tartu University brings to a conclusion that by the estimation of the employers the general skills provided specifically by universities curricula are in need, regardless to the curricula’s complete conformity to Blogna criteria and current professional standards.

  1. Vallejo-Nágera (1926-1990) and the concept of 'soteric neurosis': a forgotten sketch of hoarding disorder in the obsessive-compulsive spectrum literature.

    Science.gov (United States)

    Fontenelle, Leonardo F

    2016-02-01

    Juan Antonio Vallejo-Nágera, psychiatrist, painter and writer, wrote a widely adopted textbook of psychiatry in Spanish- and Portuguese-speaking countries, particularly during the 1970s, the famous Introducción a la psiquiatría. There, he advanced the concept of soteric neurosis, a condition regarded as a 'mirror image' of phobias and similar to the diagnostic entity described in DSM-5 under the heading of hoarding disorder. Indeed, much earlier than the recent nosological discussions on hoarding, Vallejo-Nágera already reported soteric neurosis to be distinct from obsessive-compulsive disorder and to be associated with excessive attachment to objects and positive affect (pleasure), leading to accumulation, decreased treatment seeking, increasing interference in daily activities and blurred boundaries with normality. Vallejo-Nágera also made several predictions, including the propensity soteric neurosis patients may have towards the development of separation anxiety, obesity and other 'masked' symptoms. In the light of his original and insightful contributions to the concept of hoarding disorder, it would be interesting to assess his hypotheses in future studies. © The Author(s) 2014.

    Pathological hoarding results in clutter that precludes normal activities and creates distress or dysfunction. It may lead to an inability to complete household functions, health problems, social withdrawal, and even death. The aim of this study was to describe the validation of the Brazilian version of the hoarding assessment instrument, the Saving Inventory-Revised. Sixty-five patients with obsessive-compulsive disorder (OCD) and 70 individuals from the community were assessed using the Structured Clinical Interview for the Diagnosis of DSM-IV (clinical sample), the Saving Inventory-Revised, the Obsessive-Compulsive Inventory-Revised, the Beck Depression Inventory, and the Beck Anxiety Inventory. The Brazilian version of the Saving Inventory-Revised exhibited high internal consistency (Cronbach's alpha = .94 for OCD and .84 for controls), high to moderate test-retest reliability and, using the hoarding dimension of the Obsessive-Compulsive Inventory-Revised as a reference point, high to moderate convergent validity. The Saving Inventory-Revised total scores also correlated significantly with comorbid anxiety and depressive symptoms.

  7. Cone and seed traits of two Juniperus species influence roles of frugivores and scatter-hoarding rodents as seed dispersal agents

    Science.gov (United States)

    Dimitri, Lindsay A.; Longland, William S.; Vander Wall, Stephen B.

    2017-11-01

    Seed dispersal in Juniperus is generally attributed to frugivores that consume the berry-like female cones. Some juniper cones are fleshy and resinous such as those of western juniper (Juniperus occidentalis), while others are dry and leathery such as those of Utah juniper (J. osteosperma). Rodents have been recorded harvesting Juniperus seeds and cones but are mostly considered seed predators. Our study sought to determine if rodents play a role in dispersal of western and Utah juniper seeds. We documented rodent harvest of cones and seeds of the locally-occurring juniper species and the alternate (non-local) juniper species in removal experiments at a western juniper site in northeastern California and a Utah juniper site in western Nevada. Characteristics of western and Utah juniper cones appeared to influence removal, as cones from the local juniper species were preferred at both sites. Conversely, removal of local and non-local seeds was similar. Piñon mice (Peromyscus truei) were responsible for most removal of cones and seeds at both sites. We used radioactively labeled seeds to follow seed fate and found many of these seeds in scattered caches (western juniper: 415 seeds in 82 caches, 63.0% of seeds found; Utah juniper: 458 seeds in 127 caches, 39.5% of seeds found) most of which were attributed to piñon mice. We found little evidence of frugivores dispersing Utah juniper seeds, thus scatter-hoarding rodents appear to be the main dispersal agents. Western juniper cones were eaten by frugivores, and scatter-hoarding is a complimentary or secondary form of seed dispersal. Our results support the notion that Utah juniper has adapted to xeric environments by conserving water through the loss of fleshy fruits that attract frugivores and instead relies on scatter-hoarding rodents as effective dispersal agents.

  10. Central ghrelin increases food foraging/hoarding that is blocked by GHSR antagonism and attenuates hypothalamic paraventricular nucleus neuronal activation

    Science.gov (United States)

    Thomas, Michael A.; Bartness, Timothy J.

    2015-01-01

    The stomach-derived “hunger hormone” ghrelin increases in the circulation in direct response to time since the last meal, increasing preprandially and falling immediately following food consumption. We found previously that peripheral injection of ghrelin potently stimulates food foraging (FF), food hoarding (FH), and food intake (FI) in Siberian hamsters. It remains, however, largely unknown if central ghrelin stimulation is necessary/sufficient to increase these behaviors regardless of peripheral stimulation of the ghrelin receptor [growth hormone secretagogue receptor (GHSR)]. We injected three doses (0.01, 0.1, and 1.0 μg) of ghrelin into the third ventricle (3V) of Siberian hamsters and measured changes in FF, FH, and FI. To test the effects of 3V ghrelin receptor blockade, we used the potent GHSR antagonist JMV2959 to block these behaviors in response to food deprivation or a peripheral ghrelin challenge. Finally, we examined neuronal activation in the arcuate nucleus and paraventricular hypothalamic nucleus in response to peripheral ghrelin administration and 3V GHSR antagonism. Third ventricular ghrelin injection significantly increased FI through 24 h and FH through day 4. Pretreatment with 3V JMV2959 successfully blocked peripheral ghrelin-induced increases in FF, FH, and FI at all time points and food deprivation-induced increases in FF, FH, and FI up to 4 h. c-Fos immunoreactivity was significantly reduced in the paraventricular hypothalamic nucleus, but not in the arcuate nucleus, following pretreatment with intraperitoneal JMV2959 and ghrelin. Collectively, these data suggest that central GHSR activation is both necessary and sufficient to increase appetitive and consummatory behaviors in Siberian hamsters. PMID:26561646

  11. Stroke rehabilitation reaches a threshold.

    Directory of Open Access Journals (Sweden)

    Full Text Available Motor training with the upper limb affected by stroke partially reverses the loss of cortical representation after lesion and has been proposed to increase spontaneous arm use. Moreover, repeated attempts to use the affected hand in daily activities create a form of practice that can potentially lead to further improvement in motor performance. We thus hypothesized that if motor retraining after stroke increases spontaneous arm use sufficiently, then the patient will enter a virtuous circle in which spontaneous arm use and motor performance reinforce each other. In contrast, if the dose of therapy is not sufficient to bring spontaneous use above threshold, then performance will not increase and the patient will further develop compensatory strategies with the less affected hand. To refine this hypothesis, we developed a computational model of bilateral hand use in arm reaching to study the interactions between adaptive decision making and motor relearning after motor cortex lesion. The model contains a left and a right motor cortex, each controlling the opposite arm, and a single action choice module. The action choice module learns, via reinforcement learning, the value of using each arm for reaching in specific directions. Each motor cortex uses a neural population code to specify the initial direction along which the contralateral hand moves towards a target. The motor cortex learns to minimize directional errors and to maximize neuronal activity for each movement. The derived learning rule accounts for the reversal of the loss of cortical representation after rehabilitation and the increase of this loss after stroke with insufficient rehabilitation. Further, our model exhibits nonlinear and bistable behavior: if natural recovery, motor training, or both, brings performance above a certain threshold, then training can be stopped, as the repeated spontaneous arm use provides a form of motor learning that further bootstraps performance and

    Surfaces covered by ultrathin plasmonic structures--so-called metasurfaces--have recently been shown to be capable of completely controlling the phase of light, representing a new paradigm for the design of innovative optical elements such as ultrathin flat lenses, directional couplers for surface plasmon polaritons and wave plate vortex beam generation. Among the various types of metasurfaces, geometric metasurfaces, which consist of an array of plasmonic nanorods with spatially varying orientations, have shown superior phase control due to the geometric nature of their phase profile. Metasurfaces have recently been used to make computer-generated holograms, but the hologram efficiency remained too low at visible wavelengths for practical purposes. Here, we report the design and realization of a geometric metasurface hologram reaching diffraction efficiencies of 80% at 825 nm and a broad bandwidth between 630 nm and 1,050 nm. The 16-level-phase computer-generated hologram demonstrated here combines the advantages of a geometric metasurface for the superior control of the phase profile and of reflectarrays for achieving high polarization conversion efficiency. Specifically, the design of the hologram integrates a ground metal plane with a geometric metasurface that enhances the conversion efficiency between the two circular polarization states, leading to high diffraction efficiency without complicating the fabrication process. Because of these advantages, our strategy could be viable for various practical holographic applications.

  13. ALMA Telescope Reaches New Heights

    ball at a distance of nine miles, and to keep their smooth reflecting surfaces accurate to less than the thickness of a human hair. Once the transporter reached the high plateau it carried the antenna to a concrete pad -- a docking station with connections for power and fiber optics -- and positioned it with an accuracy of a small fraction of an inch. The transporter is guided by a laser steering system and, just like some cars, also has ultrasonic collision detectors. These sensors ensure the safety of the state-of-the-art antennas as the transporter drives them across what will soon be a rather crowded plateau. Ultimately, ALMA will have at least 66 antennas distributed over about 200 pads, spread over distances of up to 11.5 miles and operating as a single, giant telescope. Even when ALMA is fully operational, the transporters will be used to move the antennas between pads to reconfigure the telescope for different kinds of observations. This first ALMA antenna at the high site will soon be joined by others, and the ALMA team looks forward to making their first observations from the Chajnantor plateau. They plan to link three antennas by early 2010, and to make the first scientific observations with ALMA in the second half of 2011. ALMA will help astronomers answer important questions about our cosmic origins. The telescope will observe the Universe using light with millimeter and submillimeter wavelengths, between infrared light and radio waves in the electromagnetic spectrum. Light at these wavelengths comes from some of the coldest, and from some of the most distant objects in the cosmos. These include cold clouds of gas and dust where new stars are being born, or remote galaxies towards the edge of the observable universe. The Universe is relatively unexplored at submillimeter wavelengths, as the telescopes need extremely dry atmospheric conditions, such as those at Chajnantor, and advanced detector technology.

  15. REACH: impact on the US cosmetics industry?

    Science.gov (United States)

    Pouillot, Anne; Polla, Barbara; Polla, Ada

    2009-03-01

    The Registration, Evaluation, Authorization and restriction of Chemicals (REACH) is a recent European regulation on chemical substances meant to protect human health and the environment. REACH imposes the "precautionary principle" where additional data and definitive action are required when uncertainty is identified. The cosmetics industry is only partially concerned by REACH: while the stages of registration and evaluation apply to cosmetics, those of authorization and restriction most likely will not, as cosmetic ingredients are already subject to regulation by various agencies and directives. REACH has potential benefits to the industry including the possibility of reassuring consumers and improving their image of chemicals and cosmetics. However, REACH also has potential disadvantages, mainly with regard to impeding innovation. The American cosmetics industry will be affected by REACH, because all US manufacturers who export substances to Europe will have to fully comply with REACH.

  16. Evidence on the Adaptive Recruitment of Chinese Cork Oak (Quercus variabilis Bl.: Influence on Repeated Germination and Constraint Germination by Food-Hoarding Animals

    2016-02-01

    Full Text Available In drought temperate forest, seedling recruitment is highly dependent on seed burial by native animal dispersers. To prolong seed storage, animals often take measures to impede seed germination. Aiming to understand the strategic balance between the natural seed germination and the role played by animals in the constraint germination procedures, we investigated the stages on the germinated acorns of Chinese cork oak (Quercus variabilis Bl. and the rodents’ behavior on the consequential delay in developmental processes of acorns in Mt. Taihangshan area of Jiyuan, Henan, China. The results showed that (1 Apodemus peninsulae Thomas excise radicles from germinated acorns before hoarding; (2 radicle-excised acorns re-germinate successfully if the excised radicle was un-lignified, but reverse if excised radicle was lignified; and (3 seedlings derived from radicle-excised acorns produce more lateral roots than that of sound acorns. We conclude that rodents take the radicle-excision behavior as a deliberate mechanism to slow the rapid germination of acorns; nevertheless, the acorns adaptively respond to this negative treatment and counteract the constraint from rodents by regermination to preserve the viability of the seeds. Consequently, this plays a significant role in forest recruitment. This study proves the new survival model of Chinese cork oak against animal predation, and will broaden theories of animal-forest interaction, forest succession and can be used as a meaningful venture to temperate forest restoration efforts.

  17. The database for reaching experiments and models.

    Directory of Open Access Journals (Sweden)

    Ben Walker

    Full Text Available Reaching is one of the central experimental paradigms in the field of motor control, and many computational models of reaching have been published. While most of these models try to explain subject data (such as movement kinematics, reaching performance, forces, etc. from only a single experiment, distinct experiments often share experimental conditions and record similar kinematics. This suggests that reaching models could be applied to (and falsified by multiple experiments. However, using multiple datasets is difficult because experimental data formats vary widely. Standardizing data formats promises to enable scientists to test model predictions against many experiments and to compare experimental results across labs. Here we report on the development of a new resource available to scientists: a database of reaching called the Database for Reaching Experiments And Models (DREAM. DREAM collects both experimental datasets and models and facilitates their comparison by standardizing formats. The DREAM project promises to be useful for experimentalists who want to understand how their data relates to models, for modelers who want to test their theories, and for educators who want to help students better understand reaching experiments, models, and data analysis.

    2015-12-01

    To examine the impact of the new Canadian tobacco package warning labels with a quitline toll-free phone number for seven provincial quitlines, focusing on treatment reach and reach equity in selected vulnerable groups. A quasi-experimental design assessed changes in new incoming caller characteristics, treatment reach for selected vulnerable sub-populations and the extent to which this reach is equitable, before and after the introduction of the labels in June, 2012. Administrative call data on smokers were collected at intake. Pre- and post-label treatment reach and reach equity differences were analysed by comparing the natural logarithms of the reach and reach equity statistics. During the six months following the introduction of the new warning labels, 86.4% of incoming new callers indicated seeing the quitline number on the labels. Treatment reach for the six-month period significantly improved compared to the same six-month period the year before from .042% to .114% (p<.0001) and reach equity significantly improved for young males (p<.0001) and those with high school education or less (p=.004). The introduction of the new tobacco warning labels with a quitline toll-free number in Canada was associated with an increase in treatment reach. The toll-free number on tobacco warning labels aided in reducing tobacco related inequalities, such as improved reach equity for young males and those with high school or less education.

    2016-01-01

    Shift workers are exposed to more physical and psychosocial stressors in the working environment as compared to day workers. Despite the need for targeted prevention, it is likely that workplace interventions less frequently reach shift workers. The aim was therefore to investigate whether the reach of workplace interventions varied between shift workers and day workers and whether such differences could be explained by the quality of leadership exhibited at different times of the day. We used questionnaire data from 5361 female care workers in the Danish eldercare sector. The questions concerned usual working hours, quality of leadership, and self-reported implementation of workplace activities aimed at stress reduction, reorganization of the working hours, and participation in improvements of working procedures or qualifications. Compared with day workers, shift workers were less likely to be reached by workplace interventions. For example, night workers less frequently reported that they had got more flexibility (OR 0.5; 95 % CI 0.3-0.7) or that they had participated in improvements of the working procedures (OR 0.6; 95 % CI 0.5-0.8). Quality of leadership to some extent explained the lack of reach of interventions especially among fixed evening workers. In the light of the evidence of shift workers' stressful working conditions, we suggest that future studies focus on the generalizability of results of the present study and on how to reach this group and meet their needs when designing and implementing workplace interventions.

  12. Action sounds modulate arm reaching movements

    Directory of Open Access Journals (Sweden)

    Ana Tajadura-Jiménez

    2016-09-01

    Full Text Available Our mental representations of our body are continuously updated through multisensory bodily feedback as we move and interact with our environment. Although it is often assumed that these internal models of body-representation are used to successfully act upon the environment, only a few studies have actually looked at how body-representation changes influence goal-directed actions, and none have looked at this in relation to body-representation changes induced by sound. The present work examines this question for the first time. Participants reached for a target object before and after adaptation periods during which the sounds produced by their hand tapping a surface were spatially manipulated to induce a representation of an elongated arm. After adaptation, participants’ reaching movements were performed in a way consistent with having a longer arm, in that their reaching velocities were reduced. These kinematic changes suggest auditory-driven recalibration of the somatosensory representation of the arm morphology. These results provide support to the hypothesis that one’s represented body size is used as a perceptual ruler to measure objects’ distances and to accordingly guide bodily actions.

    Full Text Available The history of war and conflicts is as old as human history itself. Along with it always existed attempts to find ways and means to reconcile conflicting parties and reach peace. In today’s world, more than ever, where war and conflicts are everyday occurrence is imperative to find faster and reliable ways how to resolve conflicts. Reaching a constructive compromise is extremely difficult (very often even the implementation phase creates additional hitches as the parties involved pretend or believe that all of their demands for peace deal are rational and thus should be fulfilled. While one party may have expertise in negotiation process itself, the other may be unwittingly unprepared, and believing that honesty and fairness will result in impartial peace deal. This is, unfortunately, not always so. The aim of this paper, besides targeting these types of naïve perceptions, is to inspire others to be fully prepared prior entering negotiation process. The negotiation strategy, along with steps and tactics is the fundament of this research. History of negotiations teaches us that often the strong and more prepared side tends to win more than the weak and unprepared one in a negotiation process. Yet studying and exploring the approach to reach a constructive compromise is essential and conducive even if you happen to find yourself as the weaker party vis-à-vis a stronger opposing rival. The purpose of this study is to analyse the implications of negotiating strategies in the course of reaching the eventual constructive compromise. Throughout, this paper has endeavoured to answer numerous but distinct issues related to the topic and offer a balanced analysis on the arguments explored. The study also delves into some international conflicts (resolved and unresolved examining them in light of potential constructive compromise. Finally the study ends up by concluding that constructive compromise strategy that focuses, above all, on creativity

    To investigate the effect of sensory imagery on subsequent movement, a unilateral Fleldenkrais lesson of imaging a soft bristle brush passing over one half of the body and in which no movement occurred, was given to 12 naive subjects. Forward flexion for each side of the body was measured at a sit-and-reach box. For 8 and 10 subjects who reported the perception of a side as being longer and lighter following the sensory imagery, there was also a significant increase in the forward flexion range on that side.

    Donated media placements for public service announcements (PSAs) can be difficult to secure, and may not always reach intended audiences. Strategies used by the Centers for Disease Control and Prevention's (CDC) Screen for Life: National Colorectal Cancer Action Campaign (SFL) to obtain donated media placements include producing a diverse mix of high-quality PSAs, co-branding with state and tribal health agencies, securing celebrity involvement, monitoring media trends to identify new distribution opportunities, and strategically timing the release of PSAs. To investigate open-ended recall of PSAs promoting colorectal cancer screening, CDC conducted 12 focus groups in three U.S. cities with men and women either nearing age 50 years, when screening is recommended to begin, or aged 50-75 years who were not in compliance with screening guidelines. In most focus groups, multiple participants recalled exposure to PSAs promoting colorectal cancer screening, and most of these individuals reported having seen SFL PSAs on television, in transit stations, or on the sides of public buses. Some participants reported exposure to SFL PSAs without prompting from the moderator, as they explained how they learned about the disease. Several participants reported learning key campaign messages from PSAs, including that colorectal cancer screening should begin at age 50 years and screening can find polyps so they can be removed before becoming cancerous. Donated media placements can reach and educate mass audiences, including millions of U.S. adults who have not been screened appropriately for colorectal cancer.

    2003-07-11

    During the biological survey and inventory of the Hanford Site conducted in the mid-1990s (1995 and 1996), preliminary surveys of the riparian vegetation were conducted along the Hanford Reach. These preliminary data were reported to The Nature Conservancy (TNC), but were not included in any TNC reports to DOE or stakeholders. During the latter part of FY2001, PNNL contracted with SEE Botanical, the parties that performed the original surveys in the mid 1990s, to complete the data summaries and mapping associated with the earlier survey data. Those data sets were delivered to PNNL and the riparian mapping by vegetation type for the Hanford Reach is being digitized during the first quarter of FY2002. These mapping efforts provide the information necessary to create subsequent spatial data layers to describe the riparian zone according to plant functional types (trees, shrubs, grasses, sedges, forbs). Quantification of the riparian zone by vegetation types is important to a number of DOE'S priority issues including modeling contaminant transport and uptake in the near-riverine environment and the determination of ecological risk. This work included the identification of vegetative zones along the Reach by changes in dominant plant species covering the shoreline from just to the north of the 300 Area to China Bar near Vernita. Dominant and indicator species included Agropyron dasytachyudA. smithii, Apocynum cannabinum, Aristida longiseta, Artemisia campestris ssp. borealis var scouleriana, Artemisa dracunculus, Artemisia lindleyana, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Coreopsis atkinsoniana.

    2014-08-20

    Bayesian statistics defines how new information, given by a likelihood, should be combined with previously acquired information, given by a prior distribution. Many experiments have shown that humans make use of such priors in cognitive, perceptual, and motor tasks, but where do priors come from? As people never experience the same situation twice, they can only construct priors by generalizing from similar past experiences. Here we examine the generalization of priors over stochastic visuomotor perturbations in reaching experiments. In particular, we look into how the first two moments of the prior--the mean and variance (uncertainty)--generalize. We find that uncertainty appears to generalize differently from the mean of the prior, and an interesting asymmetry arises when the mean and the uncertainty are manipulated simultaneously.

  2. New symmetry of intended curved reaches

    2010-04-01

    Full Text Available Abstract Background Movement regularities are inherently present in automated goal-directed motions of the primate's arm system. They can provide important signatures of intentional behaviours driven by sensory-motor strategies, but it remains unknown if during motor learning new regularities can be uncovered despite high variability in the temporal dynamics of the hand motions. Methods We investigated the conservation and violation of new movement regularity obtained from the hand motions traced by two untrained monkeys as they learned to reach outwardly towards spatial targets while avoiding obstacles in the dark. The regularity pertains to the transformation from postural to hand paths that aim at visual goals. Results In length-minimizing curves the area enclosed between the Euclidean straight line and the curve up to its point of maximum curvature is 1/2 of the total area. Similar trend is found if one examines the perimeter. This new movement regularity remained robust to striking changes in arm dynamics that gave rise to changes in the speed of the reach, to changes in the hand path curvature, and to changes in the arm's postural paths. The area and perimeter ratios characterizing the regularity co-varied across repeats of randomly presented targets whenever the transformation from posture to hand paths was compliant with the intended goals. To interpret this conservation and the cases in which the regularity was violated and recovered, we provide a geometric model that characterizes arm-to-hand and hand-to-arm motion paths as length minimizing curves (geodesics in a non-Euclidean space. Whenever the transformation from one space to the other is distance-metric preserving (isometric the two symmetric ratios co-vary. Otherwise, the symmetric ratios and their co-variation are violated. As predicted by the model we found empirical evidence for the violation of this movement regularity whenever the intended goals mismatched the actions. This

  3. Continental reach: The Westcoast Energy story

    Energy Technology Data Exchange (ETDEWEB)

    Newman, P. C.

    2002-07-01

    A historical account is given of the spectacular success that was Westcoast Energy Inc., a Canadian natural gas giant that charted a wilderness pipeline from natural gas fields in Canada's sub-arctic solitude. The beginning of the company is traced to an event in 1934 when near the bank of the Pouce Coupe River, close to the Alberta-British Columbia border, Frank McMahon, a solitary wildcatter and the eventual founder of the company, first sighted the fiery inferno of a runaway wildcat well, drilled by geologists of the Imperial Oil Company during their original search for the Canadian petroleum basin's motherlode. It was on this occasion in 1934 that McMahon first conceived a geological profile that connected the gas-bearing sandstone of Pouce Coupe with the reservoir rock of the biggest natural gas field of Alberta, and a pipeline from this sandstone storehouse across the rugged heart of British Columbia to Vancouver, and south into the United States. It took the better part of a quarter century to realize the dream of that pipeline which, in due course, turned out to be only the first step towards reaching the top rank of Canadian corporations in operational and financial terms, and becoming one of only a handful in terms of a story that became a Canadian corporate legend. By chronicling the lives and contributions of the company's founder and senior officials over the years, the book traces the company's meteoric rise from a gleam in its founder's eye to a cautious regional utility, and to the aggressive Canadian adventurer that went on to burst the boundaries of its Pacific Coast world, until the continental reach of its operations and interests run from Canada's Pacific shoreline to its Atlantic basins and Mexico's Campeche Bay to Alaska's Prudhoe Bay. The company's independent existence came to an end in 2002 when Westcoast Energy, by then a $15 billion operation, was acquired by Duke Energy Limited of North

Within each of these areas, we seek to build lasting programs and partnerships that will continue beyond 2009. Our weapon of choice is New Media. It is often easiest to define New Media by what it is not. Television, radio, print and their online redistribution of content are not New Media. Many forms of New Media start as user provided content and content infrastructures that answer that individual's creative whim in a way that is adopted by a broader audience. Classic examples include Blogs and Podcasts. This media is typically distributed through content specific websites and RSS feeds, which allow syndication. RSS aggregators (iTunes has audio and video aggregation abilities) allow subscribers to have content delivered to their computers automatically when they connect to the Internet. RSS technology is also being used in such creative ways as allowing automatically updating Google-maps that show the location of someone with an intelligent GPS system, and in sharing 100 word microblogs from anyone (Twitters) through a single feed. In this poster, we outline how the IYA NMWG plans to use New Media to reach target primary audiences of astronomy enthusiasts, image lovers, and amateur astronomers, as well as secondary audiences, including: science fiction fans, online gamers, and skeptics.

  5. Media perspective - new opportunities for reaching audiences

    The world of media is experiencing a period of extreme and rapid change with the rise of internet television and the download generation. Many young people no longer watch standard TV. Instead, they go on-line, talking to friends and downloading pictures, videos, music clips to put on their own websites and watch/ listen to on their laptops and mobile phones. Gone are the days when TV controllers determined what you watched and when you watched it. Now the buzzword is IPTV, Internet Protocol Television, with companies such as JOOST offering hundreds of channels on a wide range of subjects, all of which you can choose to watch when and where you wish, on your high-def widescreen with stereo surround sound at home or on your mobile phone on the train. This media revolution is changing the way organisations get their message out. And it is encouraging companies such as advertising agencies to be creative about new ways of accessing audiences. The good news is that we have fresh opportunities to reach young people through internet-based media and material downloaded through tools such as games machines, as well as through the traditional media. And it is important for Europlanet to make the most of these new and exciting developments.

  6. Important ATLAS Forward Calorimeter Milestone Reached

    Loch, P.

    The ATLAS Forward Calorimeter working group has reached an important milestone in the production of their detectors. The mechanical assembly of the first electromagnetic module (FCal1C) has been completed at the University of Arizona on February 25, 2002, only ten days after the originally scheduled date. The photo shows the University of Arizona FCal group in the clean room, together with the assembled FCal1C module. The module consists of a stack of 18 round copper plates, each about one inch thick. Each plate is about 90 cm in diameter, and has 12260 precision-drilled holes in it, to accommodate the tube/rod electrode assembly. The machining of the plates, which was done at the Science Technology Center (STC) at Carleton University, Ottawa, Canada, required high precision to allow for easy insertion of the electrode copper tube. The plates have been carefully cleaned at the University of Arizona, to remove any machining residue and metal flakes. This process alone took about eleven weeks. Exactly 122...

    Limits to athletic performance have long been a topic of myth and debate. However, sport performance appears to have reached a state of stagnation in recent years, suggesting that the physical capabilities of humans and other athletic species, such as greyhounds and thoroughbreds, cannot progress indefinitely. Although the ultimate capabilities may be predictable, the exact path for the absolute maximal performance values remains difficult to assess and relies on technical innovations, sport regulation, and other parameters that depend on current societal and economic conditions. The aim of this literature review was to assess the possible plateau of top physical capabilities in various events and detail the historical backgrounds and sociocultural, anthropometrical, and physiological factors influencing the progress and regression of athletic performance. Time series of performances in Olympic disciplines, such as track and field and swimming events, from 1896 to 2012 reveal a major decrease in performance development. Such a saturation effect is simultaneous in greyhound, thoroughbred, and frog performances. The genetic condition, exhaustion of phenotypic pools, economic context, and the depletion of optimal morphological traits contribute to the observed limitation of physical capabilities. Present conditions prevailing, we approach absolute physical limits and endure a continued period of world record scarcity. Optional scenarios for further improvements will mostly depend on sport technology and modification competition rules.

    LEP's last superconducting module leaves its home port... Just seven months into the operation, LEP dismantling is forging ahead. Two of the eight arcs which form the tunnel have already been emptied and the last of the accelerator's radiofrequency (RF) cavities has just been raised to the surface. The 160 people working on LEP dismantling have reason to feel pleased with their progress. All of the accelerator's 72 superconducting RF modules have already been brought to the surface, with the last one being extracted on 2nd May. This represents an important step in the dismantling process, as head of the project, John Poole, explains. 'This was the most delicate part of the project, because the modules are very big and they could only come out at one place', he says. The shaft at point 1.8 through which the RF cavity modules pass is 18 metres in diameter, while each module is 11.5 metres long. Some modules had to travel more than 10 kilometres to reach the shaft. ... is lifted up the PM 1.8 shaft, after a m...

    After eight years of searching for the emission of a dark matter candidate particle, the axion, from the Sun, the CERN Axion Solar Telescope (CAST) has fulfilled its original physics programme.   Members of the CAST collaboration in July, together with dipole-based helioscope. CAST, the world’s most sensitive axion helioscope, points a recycled prototype LHC dipole magnet at the Sun at dawn and dusk, looking for the conversion of axions to X-rays. It incorporates four state-of-the-art X-ray detectors: three Micromegas detectors and a pn-CCD imaging camera attached to a focusing X-ray telescope that was recovered from the German space programme (see CERN Courier April 2010).  Over the years, CAST has operated with the magnet bores - the location of the axion conversion - in different conditions: first in vacuum, covering axion masses up to 20 meV/c2, and then with a buffer gas (4He and later 3He) at various densities, finally reaching the goal of 1.17 eV/c2 on 22 ...

  10. Parallel explicit and implicit control of reaching.

    2009-10-22

    Human movement can be guided automatically (implicit control) or attentively (explicit control). Explicit control may be engaged when learning a new movement, while implicit control enables simultaneous execution of multiple actions. Explicit and implicit control can often be assigned arbitrarily: we can simultaneously drive a car and tune the radio, seamlessly allocating implicit or explicit control to either action. This flexibility suggests that sensorimotor signals, including those that encode spatially overlapping perception and behavior, can be accurately segregated to explicit and implicit control processes. We tested human subjects' ability to segregate sensorimotor signals to parallel control processes by requiring dual (explicit and implicit) control of the same reaching movement and testing for interference between these processes. Healthy control subjects were able to engage dual explicit and implicit motor control without degradation of performance compared to explicit or implicit control alone. We then asked whether segregation of explicit and implicit motor control can be selectively disrupted by studying dual-control performance in subjects with no clinically manifest neurologic deficits in the presymptomatic stage of Huntington's disease (HD). These subjects performed successfully under either explicit or implicit control alone, but were impaired in the dual-control condition. The human nervous system can exert dual control on a single action, and is therefore able to accurately segregate sensorimotor signals to explicit and implicit control. The impairment observed in the presymptomatic stage of HD points to a possible crucial contribution of the striatum to the segregation of sensorimotor signals to multiple control processes.

    Adaptive mixed reality rehabilitation (AMRR) is a novel integration of motion capture technology and high-level media computing that provides precise kinematic measurements and engaging multimodal feedback for self-assessment during a therapeutic task. We describe the first proof-of-concept study to compare outcomes of AMRR and traditional upper-extremity physical therapy. Two groups of participants with chronic stroke received either a month of AMRR therapy (n = 11) or matched dosing of traditional repetitive task therapy (n = 10). Participants were right handed, between 35 and 85 years old, and could independently reach to and at least partially grasp an object in front of them. Upper-extremity clinical scale scores and kinematic performances were measured before and after treatment. Both groups showed increased function after therapy, demonstrated by statistically significant improvements in Wolf Motor Function Test and upper-extremity Fugl-Meyer Assessment (FMA) scores, with the traditional therapy group improving significantly more on the FMA. However, only participants who received AMRR therapy showed a consistent improvement in kinematic measurements, both for the trained task of reaching to grasp a cone and the untrained task of reaching to push a lighted button. AMRR may be useful in improving both functionality and the kinematics of reaching. Further study is needed to determine if AMRR therapy induces long-term changes in movement quality that foster better functional recovery.

    Estuarine ecosystems are controlled by a variety of processes that operate at multiple spatial and temporal scales. Understanding the hierarchical nature of these processes will aid in prioritization of restoration efforts. This hierarchical Columbia River Estuary Ecosystem Classification (henceforth "Classification") of the Columbia River estuary is a spatial database of the tidally-influenced reaches of the lower Columbia River, the tidally affected parts of its tributaries, and the landforms that make up their floodplains for the 230 kilometers between the Pacific Ocean and Bonneville Dam. This work is a collaborative effort between University of Washington School of Aquatic and Fishery Sciences (henceforth "UW"), U.S. Geological Survey (henceforth "USGS"), and the Lower Columbia Estuary Partnership (henceforth "EP"). Consideration of geomorphologic processes will improve the understanding of controlling physical factors that drive ecosystem evolution along the tidal Columbia River. The Classification is organized around six hierarchical levels, progressing from the coarsest, regional scale to the finest, localized scale: (1) Ecosystem Province; (2) Ecoregion; (3) Hydrogeomorphic Reach; (4) Ecosystem Complex; (5) Geomorphic Catena; and (6) Primary Cover Class. For Levels 4 and 5, we mapped landforms within the Holocene floodplain primarily by visual interpretation of Light Detection and Ranging (LiDAR) topography supplemented with aerial photographs, Natural Resources Conservation Service (NRCS) soils data, and historical maps. Mapped landforms are classified as to their current geomorphic function, the inferred process regime that formed them, and anthropogenic modification. Channels were classified primarily by a set of depth-based rules and geometric relationships. Classification Level 5 floodplain landforms ("geomorphic catenae") were further classified based on multivariate analysis of land-cover within the mapped landform area and attributed as "sub

    Aims: The present study aims to provide observational evidence of whether coronal hole spicules reach coronal temperatures. Methods: We combine multi-instrument co-observations obtained with the SUMER/SoHO and with the EIS/SOT/XRT/Hinode. Results: The analysed three large spicules were found to be comprised of numerous thin spicules that rise, rotate, and descend simultaneously forming a bush-like feature. Their rotation resembles the untwisting of a large flux rope. They show velocities ranging from 50 to 250 kms-1. We clearly associated the red- and blue-shifted emissions in transition region lines not only with rotating but also with rising and descending plasmas. Our main result is that these spicules although very large and dynamic, are not present in the spectral lines formed at temperatures above 300 000 K. Conclusions: In this paper we present the analysis of three Ca ii H large spicules that are composed of numerous dynamic thin spicules but appear as macrospicules in lower resolution EUV images. We found no coronal counterpart of these and smaller spicules. We believe that the identification of phenomena that have very different origins as macrospicules is due to the interpretation of the transition region emission, and especially the He ii emission, wherein both chromospheric large spicules and coronal X-ray jets are present. We suggest that the recent observation of spicules in the coronal AIA/SDO 171 Å and 211 Å channels probably comes from the existence of transition region emission there.

    Poor communities in remote and inaccessible areas tend to not only be cut off from family planning education and services, but they are also deprived of basic primary health care services. Efforts to bring family planning to such communities and populations should therefore be linked with other services. The author presents three examples of programs to bring effective family planning services to remote communities in Central and South America. Outside of the municipal center in the Tuxtlas region of Mexico, education and health levels are low and people live according to ancient customs. Ten years ago with the help of MEXFAM, the IPPF affiliate in Mexico, two social promoters established themselves in the town of Catemaco to develop a community program of family planning and health care offering education and prevention to improve the quality of people's lives. Through their health brigades taking health services to towns without an established health center, the program has influenced an estimated 100,000 people in 50 villages and towns. The program also has a clinic. In Guatemala, the Family Welfare Association (APROFAM) gave bicycles to 240 volunteer health care workers to facilitate their outreach work in rural areas. APROFAM since 1988 has operated an integrated program to treat intestinal parasites and promote family planning in San Lucas de Toliman, an Indian town close to Lake Atitlan. Providing health care to more than 10,000 people, the volunteer staff has covered the entire department of Solola, reaching each family in the area. Field educators travel on motorcycles through the rural areas of Guatemala coordinating with the health volunteers the distribution of contraceptives at the community level. The Integrated Project's Clinic was founded in 1992 and currently carries out pregnancy and Pap tests, as well as general lab tests. Finally, Puna is an island in the middle of the Gulf of Guayaquil, Ecuador. Women on the island typically have 10

    Full Text Available Abstract Introduction: Functional reach (FR and lateral reach (LR tests are widely used in scientific research and clinical practice. Assessment tools are useful in assessing subjects with greater accuracy and are usually adapted according to the limitations of each condition. Objective: To adapt FR and LR tests for use in an aquatic environment and assess the performance of healthy young adults. Methods: We collected anthropometric data and information on whether the participant exercised regularly or not. The FR and LR tests were adapted for use in an aquatic environment and administered to 47 healthy subjects aged 20-30 years. Each test was repeated three times. Results: Forty-one females and six males were assessed. The mean FR test score for men was 24.06 cm, whereas the mean value for right lateral reach (RLR was 10.94 cm and for left lateral reach (LLR was 9.78 cm. For females, the mean FR score was 17.57 cm, while the mean values for RLR was 8.84cm and for LLR was 7.76 cm. Men performed better in the FR (p < 0.001 and RLR tests than women (p = 0.037. Individuals who exercised regularly showed no differences in performance level when compared with their counterparts. Conclusion: The FR and LR tests were adapted for use in an aquatic environment. Males performed better on the FR and RLR tests, when compared to females. There was no correlation between the FR and LR tests and weight, height, Body Mass Index (BMI, foot length or length of the dominant upper limb.

    This study explored the influence of an external support at the thoracic and pelvic level of the trunk on the success of reaching, postural stability and reaching kinematics while infants reached for a toy. Seventeen infants (4–6 months) were clustered into two groups according to their trunk control assessed with the Segmental Assessment of Trunk Control (SATCo). Major differences were seen between groups with pelvic support, whereas with thoracic support, all infants showed similar quality reaching behaviours. With the external pelvic support, infants who had acquired trunk control in the lumbar region were more accurate in their reaching movements (less movement time, improved straightness of reach, less movement units and path length per movement unit) and were more stable (decreased trunk and head displacement) during a reach than infants that had only acquired trunk control in the thoracic region. These results support the hypothesis that trunk control influences the quality of reaching behaviour. PMID:23681292

    Full Text Available This article presents a hoard of the Bronze Age metal objects found in the East Kazakhstan region. Parallels to the items from the hoard are found among antiquities of the Andronovo culture of the Altai, the Tien Shan area, Jetysu, Xinjiang. The assemblage from Zaisan published here enlarged the group of hoards typical for the Late Bronze Age. The most interesting objects among the ones included in the hoard are the riveted cauldron and the axe with curved butt and grid decoration. Archaeological studies revealed the wide distribution of axes with curved butts that allow us to consider them as characteristic instruments of the Late Bronze Age period in the areas of East Kazakhstan, the Altai, Jetysu, Central Asia, and the northern part of Central Asia. Researchers came to the conclusion that this type of axes can be dated to the 12th - 9th (poss. 8th centuries BC. Metal vessels of the Late Bronze Age (especially, the copper ones are rarely found in the eastern part of the Eurasian steppes. Besides the cauldron described in the article, some metal vessels were discovered in Central Kazakhstan at the cemeteries of Ashchisu and Nurataldy-1 (20th - 19th centuries BC. Also, similar objects are known among the materials of the Izmailov cemetery in East Kazakhstan, and metal items of the Andreevka hoard from south-eastern Kazakhstan dated to the 12th - 9th (poss. 8th centuries BC. Meanwhile, the closest parallels to the cauldron from the Zaisan hoard can be seen in the western part of Eurasia. Taking into account V.S. Bochkarev’s classifi cation that consists of three main groups of metal cauldrons, the vessel from East Kazakhstan may occupy an intermediate position between the groups IIB and IIIB. This allows us to date the cauldron to the end of the 13th - 12th centuries BC, while the more probable date for the Zaisan hoard as a whole lays within the range of the 12th - 9th centuries BC.

  1. Spiking and LFP activity in PRR during symbolically instructed reaches.

    Science.gov (United States)

    Hwang, Eun Jung; Andersen, Richard A

    2012-02-01

    The spiking activity in the parietal reach region (PRR) represents the spatial goal of an impending reach when the reach is directed toward or away from a visual object. The local field potentials (LFPs) in this region also represent the reach goal when the reach is directed to a visual object. Thus PRR is a candidate area for reading out a patient's intended reach goals for neural prosthetic applications. For natural behaviors, reach goals are not always based on the location of a visual object, e.g., playing the piano following sheet music or moving following verbal directions. So far it has not been directly tested whether and how PRR represents reach goals in such cognitive, nonlocational conditions, and knowing the encoding properties in various task conditions would help in designing a reach goal decoder for prosthetic applications. To address this issue, we examined the macaque PRR under two reach conditions: reach goal determined by the stimulus location (direct) or shape (symbolic). For the same goal, the spiking activity near reach onset was indistinguishable between the two tasks, and thus a reach goal decoder trained with spiking activity in one task performed perfectly in the other. In contrast, the LFP activity at 20-40 Hz showed small but significantly enhanced reach goal tuning in the symbolic task, but its spatial preference remained the same. Consequently, a decoder trained with LFP activity performed worse in the other task than in the same task. These results suggest that LFP decoders in PRR should take into account the task context (e.g., locational vs. nonlocational) to be accurate, while spike decoders can robustly provide reach goal information regardless of the task context in various prosthetic applications.

    Remarkable channel degradation has occurred in the Jingjiang Reach of the Middle Yangtze River, since the operation of the Three Gorges Project, which has caused significant geomorphic adjustments, including the variation in bankfull discharge. Bankfull discharge is a key indicator of flood-discharge capacity in the Jingjiang Reach, which can adjust in response to the altered water and sediment conditions and local base-level changes. Therefore, it is important to investigate the variation in reach-scale bankfull discharge, because of longitudinal variability in channel geometry and bankfull discharge in the study reach. In this study, a general method to calculate the section-scale bankfull discharge using the simulated stage-discharge relation is outlined briefly, and an integrated method is then presented for estimating the reach-scale bankfull discharge. The post-flood reach-scale bankfull discharges in the study reach from 2002 to 2015 were calculated, using the proposed method, based on surveyed post-flood profiles at 171 sections and measured hydrological data at three hydrometric sections and eight water gauge sections. The calculated results indicate that: (i) the reach-scale bankfull discharge in the Jingjiang Reach ranged between 32,731 and 38,949 m3/s over this period, with the average bankfull discharge in the Upper Jingjiang Reach being generally greater than the value in the Lower Jingjiang Reach; (ii) the magnitude of the reach-scale bankfull discharge responded well to the cumulative effect of incoming flow and sediment conditions at the inlet boundary, as well as the change of local base level at the outlet boundary; and (iii) the flood-discharge capacity of the reach was controlled by both the upstream and downstream boundary conditions, and the reach-scale bankfull discharge was expressed by an empirical function of the previous five-year average fluvial erosion intensity during flood seasons at Zhicheng, and the difference between the flood

    The tailwater is the reach of a stream immediately below an impoundment that is hydrologically, physicochemically and biologically altered by the presence and operation of a dam. The overall goal of this study was to gain a nationwide awareness of the issues afflicting tailwater reaches in the United States. Specific objectives included the following: (i) estimate the percentage of reservoirs that support tailwater reaches with environmental conditions suitable for fish assemblages throughout the year, (ii) identify and quantify major sources of environmental stress in those tailwaters that do support fish assemblages and (iii) identify environmental features of tailwater reaches that determine prevalence of key fish taxa. Data were collected through an online survey of fishery managers. Relative to objective 1, 42% of the 1306 reservoirs included in this study had tailwater reaches with sufficient flow to support a fish assemblage throughout the year. The surface area of the reservoir and catchment most strongly delineated reservoirs maintaining tailwater reaches with or without sufficient flow to support a fish assemblage throughout the year. Relative to objective 2, major sources of environmental stress generally reflected flow variables, followed by water quality variables. Relative to objective 3, zoogeography was the primary factor discriminating fish taxa in tailwaters, followed by a wide range of flow and water quality variables. Results for objectives 1–3 varied greatly among nine geographic regions distributed throughout the continental United States. Our results provide a large-scale view of the effects of reservoirs on tailwater reaches and may help guide research and management needs.

    Full Text Available The purpose of this paper is to summarize results on various aspects of sets with positive reach, which are up to now not available in such a compact form. After recalling briefly the results before 1959, sets with positive reach and their associated curvature measures are introduced. We develop an integral and current representation of these curvature measures and show how the current representation helps to prove integralgeometric formulas, such as the principal kinematic formula. Also random sets with positive reach and random mosaics (or the more general random cell-complexes with general cell shape are considered.

    Full Text Available In 2011, a monograph long anticipated by art historians with an expertise in Old Russian and Byzantine art was published by Ljudmila Pekarska. The main subject of the monograph - the history of a hoard of jewellery found in Kiev in 1906, and as luck would have it is today divided between the British Museum and the Metropolitan Museum of Art. The author, however, did not limit her study to the analysis of objects from this hoard. She used an extensive amount of comparative materials from collections in many Western, Ukrainian, and Russian museums. L. Pekarska focuses mainly on the cloisonné enamels, an impressive example of exquisite medieval luxury. Welcoming the publication of this book, and being interested in the research, as well as its author, I do not envy the hard work that it would take for a person to write a scholarly review on this publication.

    Objective. Despite the high number of degrees of freedom of the human hand, most actions of daily life can be executed incorporating only palmar, pincer and lateral grasp. In this study we attempt to discriminate these three different executed reach-and-grasp actions utilizing their EEG neural correlates. Approach. In a cue-guided experiment, 15 healthy individuals were asked to perform these actions using daily life objects. We recorded 72 trials for each reach-and-grasp condition and from a no-movement condition. Main results. Using low-frequency time domain features from 0.3 to 3 Hz, we achieved binary classification accuracies of 72.4%, STD  ±  5.8% between grasp types, for grasps versus no-movement condition peak performances of 93.5%, STD  ±  4.6% could be reached. In an offline multiclass classification scenario which incorporated not only all reach-and-grasp actions but also the no-movement condition, the highest performance could be reached using a window of 1000 ms for feature extraction. Classification performance peaked at 65.9%, STD  ±  8.1%. Underlying neural correlates of the reach-and-grasp actions, investigated over the primary motor cortex, showed significant differences starting from approximately 800 ms to 1200 ms after the movement onset which is also the same time frame where classification performance reached its maximum. Significance. We could show that it is possible to discriminate three executed reach-and-grasp actions prominent in people’s everyday use from non-invasive EEG. Underlying neural correlates showed significant differences between all tested conditions. These findings will eventually contribute to our attempt of controlling a neuroprosthesis in a natural and intuitive way, which could ultimately benefit motor impaired end users in their daily life actions.

  3. REACH: next step to a sound chemicals management.

    Van der Wielen, Arnold

    2007-12-01

    REACH is the new European Regulation for Registration, Evaluation, Authorisation and Restriction of Chemicals. It entered into force on 1st June 2007 to streamline and improve the former legislative framework on new and on existing chemical substances of the European Union. Companies which manufacture or import more than 1 tonne of a substance per year will be required to register the substance at the new EU Chemicals Agency located in Helsinki. REACH places greater responsibility on industry to manage the risks that chemicals may pose to the health and the environment and to provide safety information that will be passed down the supply chain. In principle, REACH applies to all chemicals as such, as components in preparations and as used in articles. REACH is a radical step forward in the EU chemicals management. The onus will move from the authorities to industry. In addition, REACH will allow the further evaluation of substances where there are grounds for concern, foresees an authorisation system for the use of substances of very high concern and a system of restrictions, where applicable, for substances of concern. The Authorisation system will require companies to switch progressively to safer alternatives where a suitable alternative exists. Current use restrictions will remain under REACH system.

  4. 'Reaching the hard to reach' - lessons learned from the VCS (voluntary and community Sector. A qualitative study

    Full Text Available Abstract Background The notion 'hard to reach' is a contested and ambiguous term that is commonly used within the spheres of social care and health, especially in discourse around health and social inequalities. There is a need to address health inequalities and to engage in services the marginalized and socially excluded sectors of society. Methods This paper describes a pilot study involving interviews with representatives from eight Voluntary and Community Sector (VCS organisations. The purpose of the study was to explore the notion of 'hard to reach' and perceptions of the barriers and facilitators to accessing services for 'hard to reach' groups from a voluntary and community sector perspective. Results The 'hard to reach' may include drug users, people living with HIV, people from sexual minority communities, asylum seekers, refugees, people from black and ethnic minority communities, and homeless people although defining the notion of the 'hard to reach' is not straight forward. It may be that certain groups resist engaging in treatment services and are deemed hard to reach by a particular service or from a societal stance. There are a number of potential barriers for people who may try and access services, including people having bad experiences in the past; location and opening times of services and how services are funded and managed. A number of areas of commonality are found in terms of how access to services for 'hard to reach' individuals and groups could be improved including: respectful treatment of service users, establishing trust with service users, offering service flexibility, partnership working with other organisations and harnessing service user involvement. Conclusions If health services are to engage with groups that are deemed 'hard to reach' and marginalised from mainstream health services, the experiences and practices for engagement from within the VCS may serve as useful lessons for service improvement for

  5. Memory-guided reaching in a patient with visual hemiagnosia.

    The two-visual-systems hypothesis (TVSH) postulates that memory-guided movements rely on intact functions of the ventral stream. Its particular importance for memory-guided actions was initially inferred from behavioral dissociations in the well-known patient DF. Despite of rather accurate reaching and grasping movements to visible targets, she demonstrated grossly impaired memory-guided grasping as much as impaired memory-guided reaching. These dissociations were later complemented by apparently reversed dissociations in patients with dorsal damage and optic ataxia. However, grasping studies in DF and optic ataxia patients differed with respect to the retinotopic position of target objects, questioning the interpretation of the respective findings as a double dissociation. In contrast, the findings for reaching errors in both types of patients came from similar peripheral target presentations. However, new data on brain structural changes and visuomotor deficits in DF also questioned the validity of a double dissociation in reaching. A severe visuospatial short-term memory deficit in DF further questioned the specificity of her memory-guided reaching deficit. Therefore, we compared movement accuracy in visually-guided and memory-guided reaching in a new patient who suffered a confined unilateral damage to the ventral visual system due to stroke. Our results indeed support previous descriptions of memory-guided movements' inaccuracies in DF. Furthermore, our data suggest that recently discovered optic-ataxia like misreaching in DF is most likely caused by her parieto-occipital and not by her ventral stream damage. Finally, multiple visuospatial memory measurements in HWS suggest that inaccuracies in memory-guided reaching tasks in patients with ventral damage cannot be explained by visuospatial short-term memory or perceptual deficits, but by a specific deficit in visuomotor processing.

    Full Text Available The aim of this study was to analyze the effect of flexibility training on the maximum range of motion levels and reach capacity of older women practitioners of aquatic exercises of the Prev-Quedas project. Participants were divided into two groups: intervention (IG, n = 25, which were submitted to flexibility training program and control (CG, n = 21, in which older women participated only in aquatic exercises. Flexibility training lasted three months with weekly frequency of two days, consisting of stretching exercises involving trunk and lower limbs performed after aquatic exercises. The stretching method used was passive static. Assessment consisted of the functional reach, lateral and goniometric tests. Statistical analysis was performed using the following tests: Shapiro-Wilk normality, ANCOVA, Pearson and Spearman correlations. Significant results for GI in gains of maximum range of motion for the right hip joint (p = 0.0025, however, the same result was not observed in other joints assessed, and there was no improvement in functional and lateral reach capacity for both groups. Significant correlations between reach capacity and range of motion in the trunk, hip and ankle were not observed. Therefore, flexibility training associated with the practice of aquatic exercises promoted increased maximum range of motion only for the hip joint; however, improvement in the reach capacity was not observed. The practice of aquatic exercises alone did not show significant results.

    Stanford University's Five-City Multifactor Risk Reduction Project (FCP) was a 14-year trial of community-wide cardiovascular disease (CVD) risk reduction through integrated programs of community organization and mass media health promotion. The project was launched in 1978 in 5 central California cities, including Monterey, Salinas, Modesto, and San Luis Obispo. TV public service announcements (PSAs), TV shows, booklets, printed tip sheets with brief health suggestions on 7 topics, and newspaper coverage were the types of mass media approaches used in the FCP. These strategies are compared with regard to reach, specificity, and impact for a 5-year study period from 1979/80. Reach is measured as the number of messages intervention community residents remembered, specificity was assessed by examining whether the campaign differentially reached people who were already knowledgeable and practicing cardiovascular disease risk reduction, and impact is defined as the amount of knowledge gained during the course of the campaign. Reach was highest for tip sheets, while specificity was highest for booklets followed by TV programs. Newspaper messages had the most impact, followed by booklets and TV PSAs, tip sheets, and TV programs. Communication channels varied according to reach, specificity, and impact, with each criterion being distinct. No channel was optimal for all 3 of the outcome measures.

    2008-03-01

    For Europe, a new regime in chemicals regulation is about to start. After the proposal of the European Commission concerning the Registration, Evaluation and Authorization of Chemicals (REACh) passed its readings in the European Parliament and some differences with the European Council of Ministers were resolved, the regulation will come into force in June 2007. This paper is focused on the question how serious the cost burdens for industry induced by REACh will be, and whether the New European Member States (NMS) which joined the European Union in May 2004 will be able to cope with the regulation. This evaluation has been done by assessing the legislative, administrative and economic framework in New Member States and by analysing real business cases in companies. The empirical showcase business impact studies are at the same time of interest for companies of EU-15 states, other European countries who may implement the regulation, and even for exporters of raw materials and chemicals outside Europe, who will also have to comply with REACh if they market in the European Community. The results give no indications that REACh adoption will bring significant drawbacks to companies in the NMS. The emerging regulation will bring challenges for individual companies, especially for small and medium-sized ones, but for the European chemical industry as a whole, there is no question that it will be able to cope with REACh burdens without losing its global competitiveness.

    Specifications of affordances is independent of the anthropometric scale of the perceiver. It is therefore predicted that sex differences disappear when perceptual performance is scaled relative to the relevant physical properties of the system formed by performer and environment in a particular action. 24 women and 30 men were compared for their ability to perceive the boundaries for overhead reaching for a ball suspended above them. Perceived and actual maximum action boundaries were measured in two height conditions, with and without wearing 15-cm high blocks under their feet. On average the men reached higher than the women; however, when perceived maximum reachable height was expressed as a ratio of actual maximum reachable height, the difference between the groups disappeared. The participants showed an identical fit between environment and performer in both height conditions. The results indicate that the specification of affordances for overhead reaching is independent of the height and the sex of the performer.

  10. From reaching to reach-to-grasp: the arm posture difference and its implications on human motion control strategy.

    Science.gov (United States)

    Li, Zhi; Milutinović, Dejan; Rosen, Jacob

    2017-05-01

    Reach-to-grasp arm postures differ from those in pure reaching because they are affected by grasp position/orientation, rather than simple transport to a position during a reaching motion. This paper investigates this difference via an analysis of experimental  data collected on reaching and reach-to-grasp motions. A seven-degree-of-freedom (DOFs) kinematic arm model with the swivel angle is used for the motion analysis. Compared to a widely used anatomical arm model, this model distinguishes clearly the four grasping-relevant DOFs (GR-DOFs) that are affected by positions and orientations of the objects to be grasped. These four GR-DOFs include the swivel angle that measures the elbow rotation about the shoulder-wrist axis, and three wrist joint angles. For each GR-DOF, we quantify position vs orientation task-relevance bias that measures how much the DOF is affected by the grasping position vs orientation. The swivel angle and forearm supination have similar bias, and the analysis of their motion suggests two hypotheses regarding the synergistic coordination of the macro- and micro-structures of the human arm (1) DOFs with similar task-relevance are synergistically coordinated; and (2) such synergy breaks when a task-relevant DOF is close to its joint limit without necessarily reaching the limit. This study provides a motion analysis method to reduce the control complexity for reach-to-grasp tasks, and suggests using dynamic coupling to coordinate the hand and arm of upper-limb exoskeletons.

    Resources for Enhancing All Caregivers Health in the Department of Veterans Affairs (REACH VA) has been implemented in the VA system as a national program for caregivers. We describe the trajectory of REACH VA from national randomized clinical trial through translation to national implementation. The implementation is examined through the six stages of the Fixsen and Blasé implementation process model: exploration and adoption, program installation, initial implementation, full operation, innovation, and sustainability. Different drivers that move the implementation process forward are important at each stage, including staff selection, staff training, consultation and coaching, staff evaluation, administrative support, program evaluation/fidelity, and systems interventions. Caregivers in the REACH VA 4 session intervention currently implemented in the VA had similar outcomes to longer REACH interventions, including Resources for Enhancing Alzheimer's Caregivers Health (REACH II). Caregivers experienced significant decreases in burden, depression, anxiety, number of troubling patient behaviors reported, caregiving frustrations, stress symptoms (feeling overwhelmed, feeling like crying, being frustrated as a result of caregiving, being lonely), and general stress. Effect sizes (Cohen's d) for these significant variables were between small and medium ranging from .24 to .46. The implementation of REACH VA provides a road map for implementation of other behavioral interventions in health care delivery settings. Lessons learned include the importance of implementing a proven, needed intervention, support from both leadership and clinical staff, willingness to respond to staff and organization needs and modify the intervention while preserving its integrity, and fitting the intervention into ongoing routines and practices.

    2012-01-01

    We effortlessly perform reach movements to objects in different directions and depths. However, how networks of cortical neurons compute reach depth from binocular visual inputs remains largely unknown. To bridge the gap between behavior and neurophysiology, we trained a feed-forward artificial neural network to uncover potential mechanisms that might underlie the 3D transformation of reach depth. Our physiologically-inspired 4-layer network receives distributed 3D visual inputs (1st layer) along with eye, head and vergence signals. The desired motor plan was coded in a population (3rd layer) that we read out (4th layer) using an optimal linear estimator. After training, our network was able to reproduce all known single-unit recording evidence on depth coding in the parietal cortex. Network analyses predict the presence of eye/head and vergence changes of depth tuning, pointing towards a gain-modulation mechanism of depth transformation. In addition, reach depth was computed directly from eye-centered (relative) visual distances, without explicit absolute depth coding. We suggest that these effects should be observable in parietal and pre-motor areas. PMID:22815979

    Becker, C.D.

    1985-09-01

    The Hanford Reach, a regulated but flowing section of the Columbia River, supports spawning populations of fall chinook salmon and steelhead. It also serves as a migration route for upriver runs of chinook, coho and sockeye salmon, and of steelhead. Environmental studies conducted in association with activities on the Hanford Site provide a basis for assessing present ecological conditions in the Hanford Reach. Spawning populations of fall chinook salmon at Hanford increased dramatically after 1960, when Priest Rapids Dam was completed, and have remained relatively stable since 1969. Generally, upriver runs of spring, summer, and fall chinook salmon have been depressed, but the fall run has been increasing since 1980. Habitat modification represents the greatest threat to sustained production of fall chinook salmon in the Hanford Reach. Operations on and near the Hanford Site releases of small amounts of radioactivity from onsite operations to river and groundwater, and operation of a steam electric plant, can have negligible effects on salmonids and other aquatic resources. Possible activities with potential future impacts include development of a multi-unit power plant complex at Hanford, construction of a low-head hydroelectric dam above Richland, flow fluctuations from peaking power generation at Priest Rapids Dam, irrigation and reductions of instream flows, and dredging and commercial navigation above Hanford. If reproducing populations of fall chinook salmon and steelhead are to survive in the mid-Columbia River, the Hanford Reach must remain flowing, undeveloped for navigation, and with unimpaired water quality. 156 refs., 16 figs., 7 tabs.

    Infants show age-related improvements in reach straightness and smoothness over the first years of life as well as a decrease in average movement speed. This period of changing kinematics overlaps the emergence of handedness. We examined whether infant hand preference status is related to the development of motor control in 53 infants ranging from 11 to 14 months old. Hand preference status was assessed from reaching to a set of 5 objects presented individually at the infant's midline; infants were classified into 'right preference' or 'no preference' groups. Three-dimensional (3-D) recordings were made of each arm for reaches under two distinct conditions: pick up a ball and fit it into the opening of a toy (grasp-to-place task) or pick up a Cheerio® and consume it (grasp-to-eat task). Contrary to expectations, there was no effect of hand preference status on reach smoothness or straightness for either task. On the grasp-to-eat task only, average speed of the left hand differed as a function of hand preference status. Infants in the no preference group exhibited higher left hand average speeds than infants in the right preference group. Our results suggest that while behavioral differences in the use of the two hands may be present in some infants, these differences do not appear to be systematically linked to biases in motor control of the arms early in development.

  11. Reach-to-grasp movement as a minimization process.

    Science.gov (United States)

    Yang, Fang; Feldman, Anatol G

    2010-02-01

    It is known that hand transport and grasping are functionally different but spatially coordinated components of reach-to-grasp (RTG) movements. As an extension of this notion, we suggested that body segments involved in RTG movements are controlled as a coherent ensemble by a global minimization process associated with the necessity for the hand to reach the motor goal. Different RTG components emerge following this process without pre-programming. Specifically, the minimization process may result from the tendency of neuromuscular elements to diminish the spatial gap between the actual arm-hand configuration and its virtual (referent) configuration specified by the brain. The referent configuration is specified depending on the object shape, localization, and orientation. Since the minimization process is gradual, it can be interrupted and resumed following mechanical perturbations, at any phase during RTG movements, including hand closure. To test this prediction of the minimization hypothesis, we asked subjects to reach and grasp a cube placed within the reach of the arm. Vision was prevented during movement until the hand returned to its initial position. As predicted, by arresting wrist motion at different points of hand transport in randomly selected trials, it was possible to halt changes in hand aperture at any phase, not only during hand opening but also during hand closure. Aperture changes resumed soon after the wrist was released. Another test of the minimization hypothesis was made in RTG movements to an object placed beyond the reach of the arm. It has previously been shown (Rossi et al. in J Physiol 538:659-671, 2002) that in such movements, the trunk motion begins to contribute to hand transport only after a critical phase when the shifts in the referent arm configuration have finished (at about the time when hand velocity is maximal). The minimization rule suggests that when the virtual contribution of the arm to hand transport is completed

    Conventional steel coiled tubing cannot reach along the entire length of very long horizontal oil wells. A lighter and more buoyant coiled tube is made possible using composite materials. The high stiffness to weight ratio of fiber reinforced polymers, coupled with a lower coefficient of friction......, has the potential of greatly extending the reach in horizontal oil wells. This study shows how to design composite coiled tubing and gives a comprehensive discussion about the most influential parameters. Several solutions, using glass-fiber and carbon are considered. Finite element models are used...... to calculate the buckling loads and the corresponding interlaminar stresses. The very positive results obtained during this study show that composite coiled tubing systems are vastly superior to their steel counterparts, and that in the future, these will become the new industry standard....

    Full Text Available BACKGROUND Atherothrombosis includes a broad spectrum of clinical manifestations (coronary artery disease, cerebrovascular disease and peripheral artery disease and is associated with the main causes of morbility and mortality on a world-wide scale. Thus far, most of the available information on atherothrombosis has been derived especially from randomized clinical trials (RCTs. Due to their strict inclusion and exclusion criteria, RCTs not always provide an accurate view of the entire spectrum of atherosclerotic clinical syndromes and are not fully representative of the real-world situation. Recently, three important observational clinical studies performed in unselected populations (REACH, PATHOS, SIRIO have described the demographic characteristics, risk profiles, management and prognosis of a very large cohort of patients suffering from atherothrombosis. AIM OF THE STUDY In this article we focus on the description of the main results of REACH, PATHOS and SIRIO studies and we discuss about their relevance in the daily clinical practice.

  14. Key Design Requirements for Long-Reach Manipulators

    Kwon, D.S.

    2001-01-01

    Long-reach manipulators differ from industrial robots and teleoperators typically used in the nuclear industry in that the aspect ratio (length to diameter) of links is much greater and link flexibility, as well as joint or drive train flexibility, is likely to be significant. Long-reach manipulators will be required for a variety of applications in the Environmental Restoration and Waste Management Program. While each application will present specific functional, kinematic, and performance requirements, an approach for determining the kinematic applicability and performance characteristics is presented, with a focus on waste storage tank remediation. Requirements are identified, kinematic configurations are considered, and a parametric study of link design parameters and their effects on performance characteristics is presented.

Advanced dense-wavelength-division-multiplexing (DWDM) equipment is used to extend the physical reach and to provide fiber gain.

  16. The leading joint hypothesis for spatial reaching arm motions.

    Science.gov (United States)

    Ambike, Satyajit; Schmiedeler, James P

    2013-02-01

    The leading joint hypothesis (LJH), developed for planar arm reaching, proposes that the interaction torques experienced by the proximal joint are low compared to the corresponding muscle torques. The human central nervous system could potentially ignore these interaction torques at the proximal (leading) joint with little effect on the wrist trajectory, simplifying joint-level control. This paper investigates the extension of the LJH to spatial reaching. In spatial motion, a number of terms in the governing equation (Euler's angular momentum balance) that vanish for planar movements are non-trivial, so their contributions to the joint torque must be classified as net, interaction or muscle torque. This paper applies definitions from the literature to these torque components to establish a general classification for all terms in Euler's equation. This classification is equally applicable to planar and spatial motion. Additionally, a rationale for excluding gravity torques from the torque analysis is provided. Subjects performed point-to-point reaching movements between targets whose locations ensured that the wrist paths lay in various portions of the arm's spatial workspace. Movement kinematics were recorded using electromagnetic sensors located on the subject's arm segments and thorax. The arm was modeled as a three-link kinematic chain with idealized spherical and revolute joints at the shoulder and elbow. Joint torque components were computed using inverse dynamics. Most movements were 'shoulder-led' in that the interaction torque impulse was significantly lower than the muscle torque impulse for the shoulder, but not the elbow. For the few elbow-led movements, the interaction impulse at the elbow was low, while that at the shoulder was high, and these typically involved large elbow and small shoulder displacements. These results support the LJH and extend it to spatial reaching motion.

    In order to reduce the cost for delivering future broadband services, network operators are inclined to simplify the network architectures by integrating the metro and access networks into a single system. Hence, extended reach passive optical networks (ER-PONs) have been proposed. ER-PON usually has four new features: high data rate in both upstream and downstream signals (>1 Gb/s); reach extension to >100 km; a high split ratio (>100); and using wavelength division multiplexing (WDM). In this work, we propose and demonstrate a highly spectral efficient ER-PON using 4 Gb/s OFDM-QAM for both upstream and downstream signals, while achieving a high split-ratio of 256. The ER-PON employs optical components optimized for GPON (bandwidth of approximately 1 GHz) and reaches 100 km without dispersion compensation. Numerical analysis using 16, 64 and 256-QAM OFDM are also performed to study the back-to-back receiver sensitivities and power penalties at different electrical driving ratios.

  20. Dealing with target uncertainty in a reaching control interface.

    Directory of Open Access Journals (Sweden)

    Elaine A Corbett

    Full Text Available Prosthetic devices need to be controlled by their users, typically using physiological signals. People tend to look at objects before reaching for them and we have shown that combining eye movements with other continuous physiological signal sources enhances control. This approach suffers when subjects also look at non-targets, a problem we addressed with a probabilistic mixture over targets where subject gaze information is used to identify target candidates. However, this approach would be ineffective if a user wanted to move towards targets that have not been foveated. Here we evaluated how the accuracy of prior target information influenced decoding accuracy, as the availability of neural control signals was varied. We also considered a mixture model where we assumed that the target may be foveated or, alternatively, that the target may not be foveated. We tested the accuracy of the models at decoding natural reaching data, and also in a closed-loop robot-assisted reaching task. The mixture model worked well in the face of high target uncertainty. Furthermore, errors due to inaccurate target information were reduced by including a generic model that relied on neural signals only.

    Prosmoking messages, delivered through marketing and the media, can reach very young children and influence attitudes and behaviors around smoking. This study examined the reach of tobacco marketing to 5 and 6 year olds in 6 low- and middle-income countries. Researchers worked one-on-one with 5 and 6 year olds in Brazil, China, India, Nigeria, Pakistan, and Russia (N = 2423). The children were asked to match logos with pictures of products, including 8 logos for cigarette brands. Analyses examined, overall and by country, whether gender, age, location, household use of tobacco, and knowledge of media characters were associated with awareness of cigarette brand logos. Additional analyses considered the relationship between cigarette brand logo awareness and intentions to smoke. Overall, 68% of 5 and 6 year olds could identify at least 1 cigarette brand logo, ranging from 50% in Russia to 86% in China. Across countries, being slightly older and having someone in the household who used tobacco, were significantly associated with greater odds of being able to identify at least 1 cigarette brand logo. The majority of young children from low- and middle-income countries are familiar with cigarette brands. This study's findings suggest that more effective measures are needed to restrict the reach of tobacco marketing.

  2. Distractor interference during a choice limb reaching task.

    Directory of Open Access Journals (Sweden)

    Matthew Ray

    Full Text Available According to action-centered models of attention, the patterns of distractor interference that emerge in selective reaching tasks are related to the time and effort required to resolve a race for activation between competing target and non-target response producing processes. Previous studies have only used unimanual aiming tasks and, as such, only examined the effects of competition that occurs within a limb. The results of studies using unimanual aiming movements often reveal an "ipsilateral effect"--distractors on the same side of space as the effector cause greater interference than distractors on the opposite side of space. The cost of the competition when response selection is between the limbs has yet to be addressed. Participants in the present study executed reaching movements to 1 of 4 (2 left, 2 right possible target locations with and without a distractor. Participants made ipsilateral reaches (left hand to left targets, right hand to right targets. In contrast to studies using unimanual aiming movements, a "contralateral effect" was observed; distractors affording responses for the other hand (in contralateral space caused more interference than distractors affording responses for the same hand. The findings from the present research demonstrate that when certain portions of response planning must be resolved prior to response initiation, distractors that code for that dimension cause the greatest interference.

    2009-10-15

    The new chemical regulation, REACH (1997/2006/EC), Registration, Evaluation, Authorization and restriction of Chemicals, took effect the 1st of June 2007. The background to this report was the introduction of REACH and the difficulties to understand the implications for ash. The most important consequence of REACH is that all chemical substances that are manufactured, handled and used above one tonne per annum per legal entity shall be registered according to this regulation. The registration includes specifying the chemical, physical, toxicity and ecotoxicity properties of the substance and risk assessing the identified areas of use. The report describes the use of ash in connection to the waste legislation and its planned end-of-waste-criteria, the chemical legislation and the Construction Products Directive. The target audience of this report is companies producing ashes and having a use or seeing a use for its ash. The report describes how to make a REACH registration of ash independent if a company did or did not pre-register ash during 2008. It describes how to change from one ash registration into another if the pre-registration was done for one type of ash but the company changes opinion during the sameness check, i.e. changing SIEF (Appendix A). Taking part in REACH registration projects during 2009-2010 can be advantageous since knowledge and financing are shared. Ash can be REACH registered also in the future but it is important to know that the registration have to be done prior the production and marketing starts. If ash is consider to be a waste the handling is covered by the community and national waste legislation. In Sweden ashes are by and large being regarded as waste, and recycling is risk assessed and permits are given case by case. End-of-waste criteria for different waste material are being elaborated within the EU. Such criteria will among other details cover chemical safety. When a material fulfils the end-of-waste criteria such material

  5. Planning reaching and grasping movements: the problem of obstacle avoidance.

    Vaughan, J; Rosenbaum, D A; Meulenbroek, R G

    2001-04-01

    In this article, we review a model of the movement-planning processes that people use for direct reaching, reaching around obstacles, and grasping, and we present observations of subjects' repeated movements of the hand to touch 2 target locations, circumventing an intervening obstacle. The model defines an obstacle as a posture that, if adopted, would intersect with any part of the environment (including the actor himself or herself). The model finds a trajectory that is likely to bring the end-effector to the target by means of a one-or two- stage planning process. Each stage exploits the principles of instance retrieval and instance generation. In the first stage, a goal posture is identified, and the trajectory of a direct transition to that posture is tested for collision. If the direct movement has no collision, the movement to the target is immediately executed in joint space. If, however, the direct movement is foreseen to result in a collision, a second planning stage is invoked. The second planing stage identifies a via posture, movement through which will probably avoid the collision. Movement to and from the via posture is then superimposed on the main movement to the target so that the combined movement reaches the target without colliding with intervening obstacles. We describe the details of instance retrieval and instance generation for each of these planning stages and compare the model's performance with the observed kinematics of direct movements as well as movements around an obstacle. Then we suggest how the model might contribute to the study of movements in people with motor disorders such as spastic hemiparesis.

    To examine the perceived relative worth of reaching and maintaining a self-selected goal weight, for obese and non-obese individuals. Cross-sectional study. Twenty-five obese treatment-seekers (age 41.0 y, BMI 42.5) and a community sample of 31 obese (age 40.8 y, BMI 32.2) and 64 non-obese participants (age 32.4 y, BMI 23.4). An 18-item forced-choice questionnaire evaluating what participants would hypothetically sacrifice to reach and maintain their goal weight. Most obese treatment-seekers would hypothetically endure much to achieve their desired weight. For example, 88% or more would forego a job promotion, retiring with full-pay, eliminating the national debt, or winning their dream house or car or an all-expense-paid vacation, and smaller majorities would suffer loss of half their income or a job demotion. Many non-treatment-seeking obese would forfeit future rewards to reach goal weight, but fewer would incur negative events. About a third of non-obese participants would forgo certain positive events, but few would suffer an adverse event to achieve goal weight. Within the combined obese sample, females viewed attaining goal weight as more important than did males, but there were no significant racial differences. An index of overall worth of weight goal was related positively to current weight and BMI and negatively to goal weight as percentage of current weight (Prealistic weight goals, particularly but not exclusively by treatment-seeking and heavier obese people and those who desire greater weight loss. Clinicians should take this phenomenon into consideration, and public health initiatives should attempt to place body weight in a more balanced perspective.

  11. Interaction torque contributes to planar reaching at slow speed

    2008-10-01

    Full Text Available Abstract Background How the central nervous system (CNS organizes the joint dynamics for multi-joint movement is a complex problem, because of the passive interaction among segmental movements. Previous studies have demonstrated that the CNS predictively compensates for interaction torque (INT which is arising from the movement of the adjacent joints. However, most of these studies have mainly examined quick movements, presumably because the current belief is that the effects of INT are not significant at slow speeds. The functional contribution of INT for multijoint movements performed in various speeds is still unclear. The purpose of this study was to examine the contribution of INT to a planer reaching in a wide range of motion speeds for healthy subjects. Methods Subjects performed reaching movements toward five targets under three different speed conditions. Joint position data were recorded using a 3-D motion analysis device (50 Hz. Torque components, muscle torque (MUS, interaction torque (INT, gravity torque (G, and net torque (NET were calculated by solving the dynamic equations for the shoulder and elbow. NET at a joint which produces the joint kinematics will be an algebraic sum of torque components; NET = MUS - G - INT. Dynamic muscle torque (DMUS = MUS-G was also calculated. Contributions of INT impulse and DMUS impulse to NET impulse were examined. Results The relative contribution of INT to NET was not dependent on speed for both joints at every target. INT was additive (same direction to DMUS at the shoulder joint, while in the elbow DMUS counteracted (opposed to INT. The trajectory of reach was linear and two-joint movements were coordinated with a specific combination at each target, regardless of motion speed. However, DMUS at the elbow was opposed to the direction of elbow movement, and its magnitude varied from trial to trial in order to compensate for the variability of INT. Conclusion Interaction torque was important at

    Current understanding of the importance of transient storage in fluvial wetlands is limited. Wetlands that have higher connectivity to the main stream channel are important because they have the potential to retain more nitrogen within the river system than wetlands that receive little direct stream discharge. In this study, we investigated how stream water accesses adjacent fluvial wetlands in New England coastal watersheds to improve parameterization in network-scale models. Break through curves of Rhodamine WT were collected for eight wetlands in the Ipswich and Parker (MA) and Lamprey River (NH) watersheds, USA. The curves were inverse modeled using STAMMT-L to optimize the connectivity and size parameters for each reach. Two approaches were tested, a single dominant storage zone and a range of storage zones represented using a power-law distribution of storage zone connectivity. Multiple linear regression analyses were conducted to relate transient storage parameters to stream discharge, area, length-to-width ratio, and reach slope. Resulting regressions will enable more accurate parameterization of surface water transient storage in network-scale models.

    Full Text Available This article presents a learning model that simulates the control of an anthropomorphic arm kinematics motion. The objective is to reach and grasp a static prototypic object placed behind different kinds of obstacle in size and position. The network, composed of two generic neural network modules, learns to combine multi-modal arm-related information (trajectory parameters as well as obstacle-related information (obstacle size and location. Our simulation was based on the notion of Via Point, which postulates that the motion planning that is divided into specific successive position of the arm. In order to determine these special points, an experimental protocol has been built and pertinent parameters have been integrated to the model. According to these studies, we propose an original method that takes into account the previous learning modules to determine the entire trajectory of the wrist in order to reach the same object placed behind two successive obstacles. The aim of this approach is to understand better the impact of experience in a task realisation and show that learning can be performed from previous initiation. Some results (applied to obstacle avoidance task show the efficiency of the proposed method.

    We examined multi-year patterns in community recovery from experimental low-concentration nutrient (N+P and P only) enrichment in three reaches of two Arctic tundra streams (Kuparuk River and Oksrukuyik Creek) on the North Slope of Alaska (USA). Rates of recovery varied among community components and depended on duration of enrichment (2 to 13 consecutive growing seasons). Biomass and C:P ratio of epilithic algae returned to reference levels rapidly (within 2 years), regardless of enrichment duration. Bryophyte cover, which increased greatly after long-term enrichment (>8 years), recovered to reference levels only after 7 years, when a storm scoured most remnant moss in the recovering reach. Persistence of bryophytes slowed recovery rates of insect taxa that had either been positively (e.g., Ephemerella, most chironomid taxa) or negatively (e.g., Orthocladius rivulorum) affected by this shift in dominant primary producer and its consequence for benthic habitat. Growth of Arctic grayling (adults and young-of-year), the top predator, returned to reference rates within two years. Recovery of these Arctic stream ecosystems from nutrient enrichment was consequently controlled largely by interactions between duration of enrichment and physical disturbance, mediated through physical habitat shifts caused by bryophytes.

  18. Reaching the hip-hop generation: Final (symposium proceedings) report

    Energy Technology Data Exchange (ETDEWEB)

    1993-05-01

    The goal of this final (closing) report is to capture the flavor of the symposium held March 1 and 2, 1993 in New York City convened by Motivational Educational Entertainment, Inc. (MEE), a black-owned communications research, consulting, and video production company based in Philadelphia, Pennsylvania. The mission of MEE is to understand, reach, and positively affect inner-city youth. Traditional communication approaches from mainstream sources to at-risk youth often don`t account for the unique way youth communicate among themselves and how they relate to the media. This understanding, however, is crucial. To understand youth communication, the people who create and send both entertaining and educational messages to urban youth must be brought into the dialogue. The meeting in New York was intended to provide an important opportunity for senders to meet and evaluate the appropriateness and effectiveness of their messages. In addition, the MEE symposium provided a forum for the continuing public debate about what needs to be done to reach today`s urban teens. Included in this document is a description of symposium goals/objectives, symposium activities, the reaction to and analysis of the symposium, recommendations for future MEE courses of action, and an appendix containing copies of press articles.

    REACH (registration, evaluation, authorisation and restriction of chemicals) regulation requires that all the chemicals produced or imported in Europe above 1 tonne/year are registered. To register a chemical, physicochemical, toxicological and ecotoxicological information needs to be reported in a dossier. REACH promotes the use of alternative methods to replace, refine and reduce the use of animal (eco)toxicity testing. Within the EU OSIRIS project, integrated testing strategies (ITSs) have been developed for the rational use of non-animal testing approaches in chemical hazard assessment. Here we present an ITS for evaluating the bioaccumulation potential of organic chemicals. The scheme includes the use of all available data (also the non-optimal ones), waiving schemes, analysis of physicochemical properties related to the end point and alternative methods (both in silico and in vitro). In vivo methods are used only as last resort. Using the ITS, in vivo testing could be waived for about 67% of the examined compounds, but bioaccumulation potential could be estimated on the basis of non-animal methods. The presented ITS is freely available through a web tool. Copyright © 2014 Elsevier Ltd. All rights reserved.

    High-channel-count WDM will eventually be used for short reach optical interconnects since it maximizes link bandwidth and efficiency. An impediment to adoption is the fact that each WDM wavelength currently requires its own DFB laser. The alternative is a single, multi-wavelength laser, but noise, size and/or expense make existing options impractical. In contrast, a new low-noise, diode comb laser based on InAs/GaAs quantum dots provides a practical and timely alternative, albeit in the O-band. Samples are being evaluated in short reach WDM development systems. Tests show this type of Fabry-Perot laser permits >10 Gb/s error-free modulation of 10 to over 50 separate channels, as well as potential for 1.25 Gb/s direct modulation. The paper describes comb laser requirements, noise measurements for external and direct modulation, O-band issues, transmitter photonic circuitry and components, future CMP applications, and optical couplers that may help drive down packaging costs to below a dollar.

    2013-01-01

    Background An international review of the Cambodian Expanded Programme on Immunization (EPI) in 2010 and other data show that despite immunization coverage increases and vaccine preventable diseases incidence reductions, inequities in access to immunization services exist. Utilizing immunization and health systems literature, analysis of global health databases and the EPI review findings, this paper examines the characteristics of immunization access and outcome inequities, and describes proposed longer-term strategic and operational responses to these problems. Findings The national programme has evolved from earlier central and provincial level planning to strengthening routine immunization coverage through the District level ‘Reaching Every District Strategy’. However, despite remarkable improvements, the review found over 20% of children surveyed were not fully immunized, primarily from communities where inequities of both access and impact persist. These inequities relate mainly to socio-economic exposures including wealth and education level, population mobility and ethnicity. To address these problems, a shift in strategic and operational response is proposed that will include (a) a re-focus of planning on facility level to detect disadvantaged communities, (b) establishment of monitoring systems to provide detailed information on community access and utilization, (c) development of communication strategies and health networks that enable providers to adjust service delivery according to the needs of vulnerable populations, and (d) securing financial, management and political commitment for ‘reaching every community’. Conclusions For Cambodia to achieve its immunization equity objectives and disease reduction goals, a shift of emphasis to health centre and community is needed. This approach will maximize the benefits of new vaccine introduction in the coming ‘Decade of Vaccines’, plus potentially extend the reach of other life-saving maternal

  2. Reaching is Better When You Get What You Want: Realtime Feedback of Intended Reaching Trajectory Despite an Unstable Environment

    Full Text Available Improvements in human-machine interaction may help overcome the unstable and uncertain environments that cause problems in everyday living. Here we experimentally evaluated intent feedback (IF, which estimates and displays the human operator's underlying intended trajectory in real-time. IF is a filter that combines a model of the arm with position and force data to determine the intended position. Subjects performed targeted reaching motions while seeing either their actual hand position or their estimated intent as a cursor while they experienced white noise forces rendered by a robotic handle. We found significantly better reaching performance during force exposure using the estimated intent. Additionally, in a second set of subjects with a reduced modeled stiffness, IF reduced estimated arm stiffness to about half that without IF, indicating a more relaxed state of operation. While visual distortions typically degrade performance and require an adaptation period to overcome, this particular distortion immediately enhanced performance. In the future, this method could provide novel insights into the nature of control. IF might also be applied in driving and piloting applications to best follow a person's desire in unpredictable or turbulent conditions.

    Dearden, J C; Rotureau, P; Fayet, G

    2013-01-01

    For registration of a chemical, European Union REACH legislation requires information on the relevant physico-chemical properties of the chemical. Predicted property values can be used when the predictions can be shown to be valid and adequate. The relevant physico-chemical properties that are amenable to prediction are: melting/freezing point, boiling point, relative density, vapour pressure, surface tension, water solubility, n-octanol-water partition coefficient, flash point, flammability, explosive properties, self-ignition temperature, adsorption/desorption, dissociation constant, viscosity, and air-water partition coefficient (Henry's law constant). Published quantitative structure-property relationship (QSPR) methods for all of these properties are discussed, together with relevant property prediction software, as an aid for those wishing to use predicted property values in submissions to the European Chemicals Agency (ECHA).

    2010-01-01

    The search for physics beyond the Standard Model (BSM) is one of the most important goals for the general purpose detector ATLAS at the Large Hadron Collider at CERN. We review some of the current strategies to search for generic SUSY models with R-parity conservation in channels with jets, leptons and missing transverse energy for an integrated luminosity of L = 200 pb^-1 at a centre-of-mass energy s = $10TeV. Only a selection of the results is presented with a focus on the discovery potential for inclusive searches. The discovery reach for a centre-of-mass energy of s = 7TeV and an integrated luminosity of L = 1 fb^-1 is expected to be very similar to the one discussed in this note.

    Goldsmith, Moshe; Tawfik, Dan S

    2017-10-13

    The practical need for highly efficient enzymes presents new challenges in enzyme engineering, in particular, the need to improve catalytic turnover (kcat) or efficiency (kcat/KM) by several orders of magnitude. However, optimizing catalysis demands navigation through complex and rugged fitness landscapes, with optimization trajectories often leading to strong diminishing returns and dead-ends. When no further improvements are observed in library screens or selections, it remains unclear whether the maximal catalytic efficiency of the enzyme (the catalytic 'fitness peak') has been reached; or perhaps, an alternative combination of mutations exists that could yield additional improvements. Here, we discuss fundamental aspects of the process of catalytic optimization, and offer practical solutions with respect to overcoming optimization plateaus. Copyright © 2017 Elsevier Ltd.

  6. ECONOMIC INTEGRATION AND STATIST REACH - TOWARDS A HOLISTIC ASSESMENT

    Directory of Open Access Journals (Sweden)

    Clara Volintiru

    2011-03-01

    Full Text Available This paper assesses the relationship between public governance and economic competitiveness in a globalized world. The extent of statist reach is often seen as being reduced by the integrated world economy. The present article argues that this is not necessarily so: economic development is not mutually exclusive with good governance. Although international economic actors often tend to use the 'exit' strategy, by choosing those markets that are least regulated, as the globalization process homogenizes further on the world markets, inter-state synchronization of environmental, labour or fiscal regulation must be achieved. As this article argues, such accountability mechanisms will not thwart economic prosperity, but rather secure its further development in a predictable and secure environment for both citizens and firms.

    2008-10-01

    Due to a number of drawbacks associated with the previous regime for the assessment of new and existing chemicals, the European Union established a new regulation concerning the registration, evaluation, authorisation and restriction of chemicals (REACH). All relevant industrial chemicals must now be assessed. Instead of the authorities, industry itself is responsible for the risk assessment. To achieve better and more efficient assessments while reducing animal testing, all information-standard, non-standard and non-testing-has to be used in an integrated manner. To meet these challenges, the current technical guidance documents for risk assessment of new and existing chemicals had to be updated and extended considerably. This was done by experts in a number of REACH Implementation Projects. This paper presents the most relevant results of the expert Endpoint Working Group on Aquatic Toxicity in order to illustrate the change of paradigm in the future assessment of hazards to the aquatic environment by chemical substances. REACH sets certain minimum data requirements in order to achieve a high level of protection for human health and the environment. It encourages the assessor to use alternative information instead of or in addition to standard one. This information has to be equivalent to the standard information requirement and adequate to draw overall conclusions with respect to the regulatory endpoints classification and labelling, persistent, bioaccumulative and toxic (PBT) assessment and predicted no-effect concentrations (PNEC) derivation. The main task of the expert working group was to develop guidance on how to evaluate the toxicity of a substance based on integration of information from different sources and of various degrees of uncertainty in a weight of evidence approach. In order to verify the equivalence and adequacy of different types of information, a flexible sequence of steps was proposed, covering characterisation of the substance, analysis of

    Mitochondria move throughout neuronal dendrites and localize to sites of energy demand. The prevailing view of dendritic mitochondria as highly motile organelles whose distribution is continually adjusted by neuronal activity via Ca(2+)-dependent arrests is based on observations in cultured neurons exposed to artificial stimuli. Here, we analyze the movements of mitochondria in ganglion cell dendrites in the intact retina. We find that whereas during development 30% of mitochondria are motile at any time, as dendrites mature, mitochondria all but stop moving and localize stably to synapses and branch points. Neither spontaneous nor sensory-evoked activity and Ca(2+) transients alter motility of dendritic mitochondria; and pathological hyperactivity in a mouse model of retinal degeneration elevates rather than reduces motility. Thus, our findings indicate that dendritic mitochondria reach stable positions during a critical developmental period of high motility, and challenge current views about the role of activity in regulating mitochondrial transport in dendrites.

  9. Rapid Automatic Motor Encoding of Competing Reach Options

    Directory of Open Access Journals (Sweden)

    Jason P. Gallivan

    2017-02-01

    Full Text Available Mounting neural evidence suggests that, in situations in which there are multiple potential targets for action, the brain prepares, in parallel, competing movements associated with these targets, prior to implementing one of them. Central to this interpretation is the idea that competing viewed targets, prior to selection, are rapidly and automatically transformed into corresponding motor representations. Here, by applying target-specific, gradual visuomotor rotations and dissociating, unbeknownst to participants, the visual direction of potential targets from the direction of the movements required to reach the same targets, we provide direct evidence for this provocative idea. Our results offer strong empirical support for theories suggesting that competing action options are automatically represented in terms of the movements required to attain them. The rapid motor encoding of potential targets may support the fast optimization of motor costs under conditions of target uncertainty and allow the motor system to inform decisions about target selection.

    In April 2014, the Nuclear Science Advisory Committee was charged to conduct a new study of the opportunities and priorities for United States nuclear physics research and to recommend a long range plan for the coordinated advancement of the Nation's nuclear science program over the next decade. The entire community actively contributed to developing this plan. Ideas and goals, new and old, were examined and community priorities were established. The Long Range Plan Working Group gathered at Kitty Hawk, NC to converge on the recommendations. In this talk I will discuss the vision for the future that has emerged from this process. The new plan, ``Reaching for the Horizon,'' offers the promise of great leaps forward in our understanding of nuclear science and new opportunities for nuclear science to serve society.

    Canada is very large geographically, so many rural communities are very far from major centers. People in such communities are at a severe disadvantage when it comes to in-person interaction with science or scientists because resources tend to be directed at large population centers, where more people can be reached for the same amount of effort. While this geographic distance can be mitigated by doing outreach over the internet, there is at some level no substitute for showing up in person with e.g. meteorites in hand. Due to where various members of my family are located, I have occasion to visit Whitehorse, YT and Andrew, AB (~1.5 hour drive north-east of Edmonton) and have taken advantage of trips to these locations to do astronomy outreach in both schools and public libraries. I will discuss how I arranged school and library visits and general observations from my experience doing outreach in rural Canadian communities.

  13. The contributions of vision and haptics to reaching and grasping

    2015-09-01

    Full Text Available This review aims to provide a comprehensive outlook on the sensory (visual and haptic contributions to reaching and grasping. The focus is on studies in developing children, normal and neuropsychological populations, and in sensory-deprived individuals. Studies have suggested a right-hand/left-hemisphere specialization for visually-guided grasping and a left-hand/right-hemisphere specialization for haptically-guided object recognition. This poses the interesting possibility that when vision is not available and grasping relies heavily on the haptic system, there is an advantage to use the left hand. We review the evidence for this possibility and dissect the unique contributions of the visual and haptic systems to grasping. We ultimately discuss how the integration of these two sensory modalities shape hand preference.

    Genesee County Racial and Ethnic Approaches to Community Health Program (REACH) is a Community-Based Public Health partnership for reducing African American infant mortality rates that hosts the Undoing Racism Workshop (URW). Assess the URW's effectiveness in promoting an understanding of racism, institutional racism, and how issues related to race/ethnicity can affect maternal and infant health. Recent URW participants (n=84) completed brief preassessment and postassessment forms; participants (n=101) also completed an on-line, long-term assessment (LTA). URWs promoted understanding of racism and institutional racism, although they were less effective in addressing racism as related to maternal and infant health. The URWs were most effective in the domains related to their standard content. Additional effort is necessary to customize URWs when utilized for activities beyond their original purpose of community mobilization.

    China actively promotes child health in the international arena. It has signed the Declaration for the World Summit for Children in 1991, contributed to the drafting of and ratified the Convention on the Rights of the Child, and supports the UN General Assembly's approval of the Convention. The government has established a National Program of Action for Children, which has 10 major goals for the year 2000. In January, 1992, it passed a comprehensive national law on the protection of juveniles that secures children's rights. The infant mortality rate in China has fallen from 200 to 34/1000 live births in the last 40 years. Severe malnutrition among 5-year-old children is rare. Almost all children (95%) have been vaccinated against common childhood diseases. Nationwide, primary school enrollment has reached 97%. In 1993, 207 hospitals have achieved Baby Friendly status, indicating that they promote breast feeding. China needs a system to monitor child health and to identify ways to reach those children who do not have access to quality health care. About 40% of all cases of iodine deficiency in the world live in China. With support from UN agencies and WHO, China has stepped up efforts to eliminate iodine deficiency disorders, particularly in women and children, by the year 2000. Since China is experiencing 2 new phenomena (1-child families and change in family values as a result of rapid socioeconomic development), the country should develop and foster strategies to improve, support, and recognize the family as the social unit which provides proper child development. China aims to eliminate polio and neonatal tetanus by 1995. China's commitment to child health, proper use of resources, and the public's support for child health development indicate that China faces a prosperous future for its children.

  16. Effects of aging on interjoint coordination during arm reaching

    Directory of Open Access Journals (Sweden)

    Marcus Vinicius da Silva

    Full Text Available Abstract Introduction Moving the arm towards an object is a complex task. Movements of the arm joints must be well coordinated in order to obtain a smooth and accurate hand trajectory. Most studies regarding reaching movements address young subjects. Coordination differences in the neural mechanism underlying motor control throughout the life stages is yet unknown. The understanding of these changes can lead to a better comprehension of neuromotor pathologies and therefore to more suitable therapies. Methods Our purpose was to investigate interjoint coordination in three different aging groups (children, young, elderly. Kinematics and kinetics specific variables were analyzed focusing on defined parameters to get insight into arm coordination. Intersegmental dynamics was used to calculate shoulder and elbow torques assuming a 2-link segment model of the upper extremity (upper arm and forearm with two friction-less joints (shoulder and elbow. A virtual reality environment was used to examine multidirectional planar reaching in three different directions (randomly presented. Results Seven measures were computed to investigate group interlimb differences: shoulder and elbow muscle torques (peak and impulse, work performed by shoulder and elbow joints, maximum velocity, movement distance, distance error at final position, movement duration and acceleration duration. Our data analysis showed differences between movement performances for all analyzed variables, at all ages. Conclusion We found that the intersegmental dynamics for the interlimb (left/right comparisons were similar for the elderly and children groups as compared to the young. In addition, the coordination and control of motor tasks changes during life, becoming less effective in old age.

    African dust can transport across the tropical Atlantic and reach the Amazon basin, exerting far-reaching impacts on climate in downwind regions. The transported dust influences the surface-atmosphere interactions and cloud and precipitation processes through perturbing the surface radiative budget and atmospheric radiative heating and acting as cloud condensation nuclei and ice nuclei. Dust also influences biogeochemical cycle and climate through providing nutrients vital to the productivity of ocean biomass and Amazon forests. Assessing these climate impacts relies on an accurate quantification of dust transport and deposition. Currently model simulations show extremely large diversity, which calls for a need of observational constraints. Kaufman et al. (2005) estimated from MODIS aerosol measurements that about 144 Tg of dust is deposited into the tropical Atlantic and 50 Tg of dust into the Amazon in 2001. This estimated dust import to Amazon is a factor of 3-4 higher than other observations and models. However, several studies have argued that the oversimplified characterization of dust vertical profile in the study would have introduced large uncertainty and very likely a high bias. In this study we quantify the trans-Atlantic dust transport and deposition by using 7 years (2007-2013) observations from CALIPSO lidar. CALIPSO acquires high-resolution aerosol extinction and depolarization profiles in both cloud-free and above-cloud conditions. The unique CALIPSO capability of profiling aerosols above clouds offers an unprecedented opportunity of examining uncertainties associated with the use of MODIS clear-sky data. Dust is separated from other types of aerosols using the depolarization measurements. We estimated that on the basis of 7-year average, 118142 Tg of dust is deposited into the tropical Atlantic and 3860 Tg of dust into the Amazon basin. Substantial interannual variations are observed during the period, with the maximum to minimum ratio of about 1

    With the positioning of the 616th magnet, installation of the LHC dipoles has reached the half-way mark. Only half the dipoles remain to be installed! The 616th dipole out of a total of 1232 was installed at 3 a.m on Wednesday 12 July. Night and day, the tunnel is the setting for a never-ending series of carefully choreographed installation operations. At a rate of around twenty per week, there has been a steady underground flow of dipole magnets, each measuring 15 metres in length and weighing 34 tonnes. 'In order to recover the accumulated delays, installation is proceeding three times faster than planned', confides Claude Hauviller, who is supervising LHC installation. Four dipoles can be transported underground at the same time. It is a real challenge, which the 65-man team responsible for this difficult task faces on a daily basis. This is because there is very little space in the tunnel and there are no passing places for the magnet transport vehicles. The room for manoeuvre can sometimes be measured ...

    Background To ensure the rigour of objective structured clinical examinations (OSCEs) in assessing medical students, medical school educators must educate examiners with a view to standardising examiner assessment behaviour. Delivering OSCE examiner training is a necessary yet challenging part of the OSCE process. A novel approach to implementing training for current and potential OSCE examiners was trialled by delivering large-group education sessions at major teaching hospitals. Methods The 'OSCE Roadshow' comprised a short training session delivered in the context of teaching hospital 'Grand Rounds' to current and potential OSCE examiners. The training was developed to educate clinicians about OSCE processes, clarify the examiners' role and required behaviours, and to review marking guides and mark allocation in an effort to standardise OSCE processes and encourage consistency in examiner marking behaviour. A short exercise allowed participants to practise marking a mock OSCE to investigate examiner marking behaviour after the training. Results OSCE Roadshows at four metropolitan and one rural teaching hospital were well received and well attended by 171 clinicians across six sessions. Unexpectedly, medical students also attended in large numbers (n=220). After training, participants' average scores for the mock OSCE clustered closely around the ideal score of 28 (out of 40), and the average scores did not differ according to the levels of clinical experience. Conclusion The OSCE Roadshow demonstrated the potential of brief familiarisation training in reaching large numbers of current and potential OSCE examiners in a time and cost-effective manner to promote standardisation of OSCE processes.

    Final height in boys with delayed puberty is thought to be below target height. This conclusion, however, is based on studies that included patients with genetic short stature. We therefore studied final height in a group of 33 untreated boys with delayed puberty with a target height >-1.5 SDS. Standing height, sitting height, weight and arm span width were measured in each patient. Final height was predicted by the method of Greulich and Pyle using the tables of Bailey and Pinneau for retarded boys at their bone age (PAH1) and the tables of Bailey and Pinneau for average boys plus six months (PAH2). Mean final height (175.8 +/- 6.5 cm) was appropriate for the mean target height (174.7 +/- 4.5 cm). The prediction method of Bailey and Pinneau overestimated the final height by 1.4 cm and the modified prediction method slightly underestimated the final height (-0.15 cm). Boys with untreated delayed puberty reach a final height appropriate for their target height. Final height was best predicted by the method of Bailey and Pinneau using the tables for average boys at their bone age plus six months. Copyright 2008 S. Karger AG, Basel.

  6. Dendritic mitochondria reach stable positions during circuit development

    Mitochondria move throughout neuronal dendrites and localize to sites of energy demand. The prevailing view of dendritic mitochondria as highly motile organelles whose distribution is continually adjusted by neuronal activity via Ca2+-dependent arrests is based on observations in cultured neurons exposed to artificial stimuli. Here, we analyze the movements of mitochondria in ganglion cell dendrites in the intact retina. We find that whereas during development 30% of mitochondria are motile at any time, as dendrites mature, mitochondria all but stop moving and localize stably to synapses and branch points. Neither spontaneous nor sensory-evoked activity and Ca2+ transients alter motility of dendritic mitochondria; and pathological hyperactivity in a mouse model of retinal degeneration elevates rather than reduces motility. Thus, our findings indicate that dendritic mitochondria reach stable positions during a critical developmental period of high motility, and challenge current views about the role of activity in regulating mitochondrial transport in dendrites.

    Previous observations have shown a ˜10-15 min time delay in the ionospheric response to solar wind directional discontinuities marked by either southward or northward interplanetary magnetic field (IMF) turnings. We have studied one southward IMF turning observed by Time History of Events and Macroscale Interactions during Substorms (THEMIS) and GOES in the dayside magnetosphere. Using a global MHD model, we have reproduced the magnetopause motion in this event. We find that the observed delay in the ground response can be completely explained by deceleration of the directional discontinuity in the subsolar magnetosheath. We show that the speed of the discontinuity significantly decreases in the vicinity of the magnetopause where the magnetic barrier formed during the previous northward IMF interval. The southward turning can reach the magnetopause only after complete disruption of the magnetic barrier. The disruption or dissipation occurs via magnetosheath reconnection, as confirmed by high-speed jets in the magnetosheath. The magnetopause moves sunward as the directional discontinuity transits the magnetosheath. This sunward motion is followed by the earthward motion when the discontinuity strikes the magnetopause and magnetopause reconnection begins.

    The assembly and integration of the Big Wheels sectors of the Muon Spectrometer is reaching its conclusion, with only a few sectors of Wheel TGC-A-3 remaining on the assembly stations in building 180. The six trigger chambers (TGCs) wheels and two precision chambers wheels (MDTs) contain in total 104 sectors, which were assembled, equipped with detectors and fully tested over a period of two years. The few remaining Big Wheel sectors still stored in building 180 Most of the sectors left building 180 over the last twelve months, and form the six Wheels currently installed in the ATLAS detector. The remaining two will be installed before the end of the summer. The commitment of the personnel from the many teams who contributed to different parts of the project was essential to its success. In particular, teams coming from countries of different traditions and languages, such as China, Israel, Japan, Pakistan, Russia and USA contributed and collaborated very effectively to the timely completion of the p...

    We describe how availability of new solar electric propulsion (SEP) technology can substantially increase the science capability of space astronomy missions working within the near-UV to far-infrared (UVOIR) spectrum by making dark sky orbits accessible for the first time. We present two case studies in which SEP is used to enable a 700 kg Explorer-class and 7000 kg flagship-class observatory payload to reach an orbit beyond where the zodiacal dust limits observatory sensitivity. The resulting scientific performance advantage relative to a Sun-Earth L2 point (SEL2) orbit is presented and discussed. We find that making SEP available to astrophysics Explorers can enable this small payload program to rival the science performance of much larger long development-time systems. Similarly, we find that astrophysics utilization of high power SEP being developed for the Asteroid Redirect Robotics Mission (ARRM) can have a substantial impact on the sensitivity performance of heavier flagship-class astrophysics payloads such as the UVOIR successor to the James Webb Space Telescope.

  10. How Physics World reaches out in a digital age

    Science.gov (United States)

    Durrani, Matin

    Physics World is an award-winning international magazine that exists in print and digital formats. Exploiting the opportunities available with digital publishing and apps, our output has expanded hugely in recent years to include technology-linked focus issues, regional special reports on the likes of China, India, Mexico and Brazil, plus audio, video and interactive material too. This growth in content - and new media for presenting physics - reflects wider changes in communication. People increasingly want to access content in a manner and time of their choosing, seeking out information presented in a way that suits them and their needs. That can be challenging for physics communicators because it means tailoring your message to different audiences and the medium they are using. But it's exciting too as you can reach out to many more people into physics - and in many different ways - than was possible in the past. This talk outlines some principles of good communication, including telling a good story, bearing the reader, viewer or listener in mind, using appropriate media, keeping up with social media, and exploiting the power of video. But with new forms of communication constantly emerging, it's worth remembering there is no one ``right answer''.

    Predicting the performance of a crewmember in an extravehicular activity (EVA) space suit presents unique challenges. The kinematic patterns of suited motions are difficult to reproduce in gravity. Additionally, 3-D suited kinematics have been practically and technically difficult to quantify in an underwater environment, in which crewmembers are commonly trained and assessed for performance. The goal of this study is to develop a hardware and software system to predictively evaluate the kinematic mobility of suited crewmembers, by measuring the 3-D reach envelope of the suit in an underwater environment. This work is ultimately aimed at developing quantitative metrics to compare the mobility of the existing Extravehicular Mobility Unit (EMU) to newly developed space suit, such as the Z-2. The EMU has been extensively used at NASA since 1981 for EVA outside the Space Shuttle and International Space Station. The Z-2 suit is NASA's newest prototype space suit. The suit is comprised of new upper torso and lower torso architectures, which were designed to improve test subject mobility.

    Effectively communicating river research to water professionals and researchers working in multiple disciplines or organizations is challenging. RiverCare studies the mid-term effects of innovative river interventions in the Netherlands to improve river governance and sustainable management. A total of 21 researchers working at 5 universities are part of the consortium, which also includes research institutes, consultancies, and water management authorities. RiverCare results do not only benefit Dutch river management, but can also provide useful insights to challenges abroad. Dutch partner organizations actively involved in RiverCare are our direct users. However, we want to reach water professionals from the Netherlands and beyond. To communicate with and disseminate to these users, we set up a communication strategy that includes the following approaches : (1) Netherlands Centre of River studies (NCR) website to announce activities post news, not limited to RiverCare; (2) A RiverCare newsletter that is published twice per year to update about our progress and activities; (3) A multimedia promotional providing a 'first glance' of RiverCare. It consists of four video episodes and an interactive menu; (4) An interactive knowledge platform to provide access, explain RiverCare results and gather feedback about the added value and potential use of these results; and (5) A serious gaming environment titled Virtual River where actors can play out flood scaling intervention and monitoring strategies to assess maintenance scenarios. The communication strategy and related approaches are being designed and developed during the project. We use participatory methods and systematic evaluation to understand communication needs and to identify needs for improvement. As a first step, RiverCare information is provided via the NCR website. The active collaboration with the NCR is important to extend communication efforts beyond the RiverCare consortium and after the program ends

    Tobacco companies are restricted from engaging in many traditional forms of marketing. Direct marketing is one way tobacco companies can reach consumers while complying with regulation and avoiding negative public perception. There is little research on this type of opt-in marketing, which includes mail marketing, email marketing, web marketing, and mobile marketing, and its impact is not well understood. This study examined 6990 tobacco company emails received by individuals living in the state of Minnesota, US between January 2010 and May 2015 to determine email frequency by brand. These emails were gathered as part of ongoing surveillance of tobacco industry direct marketing. A subset of these emails received between October 2014 and May 2015 (n = 1646) were content analyzed to identify the purpose of the email communication along with type of product promoted. Tobacco companies use email to communicate with consumers on a regular basis. This communication was observed to be as frequent as nine times per month. Emails are most commonly used to promote contests (54.1%), content on tobacco company websites (39.1%), and tobacco coupons (15.7%). Email promotion of menthol-flavored tobacco products was common and was associated with promotion of coupons. Emails promoting menthol had a 1.9 times higher prevalence of also promoting coupons (95% CI: 1.52-2.37). Little is known about tobacco company email marketing and this study fills an identified research gap. A deeper understanding of this type of marketing is needed in order to counter tobacco industry messaging and advance tobacco control.

    The U.S. Department of Health and Human Services has promoted Healthy People 2010, which is a set of national health objectives for the nation to achieve over the first decade of the new century (1). Texas has not yet met its target of 50 percent of 8-year-old children with dental sealants having been placed on their 6-year molars, which is one of the Healthy People 2010 goals. An assessment of the dental needs of children in Tarrant County, Texas, was initiated by the JPS Health Network (named after John Peter Smith). The JPS Health Network established the Healthy Smiles program to address the dental needs of the students in this county because a school based dental sealant program would be effective in reducing dental decay. Approved Title One elementary schools in Tarrant County were scheduled for dental screenings, education, and fluoride and dental sealant applications. Students were given visual dental screenings and classified as to future dental needs. First grade students received fluoride varnish and second and third grade students received fluoride and dental sealants. For the 2010-2011 school year: A total of 28,322 students were seen by dental professionals from the JPS Health Network; 8,348 dental sealants were placed; and 11,825 fluoride applications were given by dental staff. The JPS Health Network Healthy Smiles Program proved to be an effective way to deliver oral preventive care and dental education to a large number of low-income students. Dental caries prevention programs such as Healthy Smiles could help Texas reach its goals for improved oral health for the children of Texas.

  17. Is the full potential of the biopharmaceutics classification system reached?

    Bergström, Christel A S; Andersson, Sara B E; Fagerberg, Jonas H; Ragnarsson, Gert; Lindahl, Anders

    2014-06-16

    In this paper we analyse how the biopharmaceutics classification system (BCS) has been used to date. A survey of the literature resulted in a compilation of 242 compounds for which BCS classes were reported. Of these, 183 compounds had been reported to belong to one specific BCS class whereas 59 compounds had been assigned to multiple BCS classes in different papers. Interestingly, a majority of the BCS class 2 compounds had fraction absorbed (FA) values >85%, indicating that they were completely absorbed after oral administration. Solubility was computationally predicted at pH 6.8 for BCS class 2 compounds to explore the impact of the pH of the small intestine, where most of the absorption occurs, on the solubility. In addition, the solubilization capacity of lipid aggregates naturally present in the intestine was studied computationally and experimentally for a subset of 12 compounds. It was found that all acidic compounds with FA>85% were completely dissolved in the pH of the small intestine. Further, lipids at the concentration used in fasted state simulated intestinal fluid (FaSSIF) dissolved the complete dose given of the most lipophilic (logD6.5>3) compounds studied. Overall, biorelevant dissolution media (pure buffer of intestinal pH or FaSSIF) identified that for 20 of the 29 BCS class 2 compounds with FA>85% the complete dose given orally would be dissolved. These results indicate that a more relevant pH restriction for acids and/or dissolution medium with lipids present better forecast solubility-limited absorption in vivo than the presently used BCS solubility criterion. The analysis presented herein further strengthens the discussion on the requirement of more physiologically relevant dissolution media for the in vitro solubility classification performed to reach the full potential of the BCS.

  18. Sarpa salpa herbivory on shallow reaches of Posidonia oceanica beds

    2014-06-01

    Full Text Available Here, we examined the temporal and small–scale spatial variability of grazing by the herbivorous fish Sarpa salpa on shallow beds of the temperate seagrass Posidonia oceanica. Herbivory intensity expressed as the percent of leaf area taken by fish bites was higher in September 2006 than in February 2007, and at 0.5 m than at 1.5 m during both sampling times. All S. salpa feeding at the shallow locations studied were juveniles, with bite sizes ranging from 0.03 to 0.62 cm2. Juveniles feeding at 1.5 m were larger in February 2007 than in September 2006, as evidenced by significant differences in mean bite size per shoot. However, the larger juveniles feeding at 1.5 m in February 2007 did not appear to feed as frequently as the comparatively smaller juveniles feeding at the same depth in September 2006, as suggested by significant differences in number of bites per shoot. The number of bites per shoot was also lower at 1.5 m than at 0.5 m in February 2007, although mean bite size did not differ significantly between the two depths at that sampling time. In general S. salpa juveniles did not select a particular range of leaf ages when feeding in the study locations, although the juveniles feeding at 1.5 m in September 2006 appeared to select mid–aged leaves. Fish did not show a preference for more epiphytized leaves. These results show that grazing activity by S. salpa juveniles in shallow reaches of P. oceanica meadows may vary temporally and across small changes in depth, which in turn may affect the overall intensity of herbivory on the seagrass.

    "We were the first that ever burst/Into that silent sea," the title character recounts in Samuel Taylor Coleridge s opus Rime of the Ancient Mariner. This famous couplet is equally applicable to undersea exploration today as surface voyages then, and has recently been applied to space travel in the title of a chronicle of the early years of human space flight ("Into That Silent Sea: Trailblazers of the Space Era, 1961-1965"), companion to the +n the Shadow of the Moon book and movie. The parallel is certainly fitting, considering both fields explore unknown, harsh, and tantalizingly inhospitable environments. For starters, exploring the Briny Deep and the Final Frontier requires special vehicles, and the most economical and safest means for each employ remotely operated vehicles (ROVs). ROVs have proven the tool of choice for exploring remote locations, allowing scientists to explore the deepest part of the sea and the furthest reaches of the solar system with the least weight penalty, the most flexibility and specialization of design, and without the need to provide for sustaining human life, or the risk of jeopardizing that life. Most NASA probes, including the historic Voyager I and II spacecraft and especially the Mars rovers, Spirit and Opportunity, feature remote operation, but new missions and new planetary environments will demand new capabilities from the robotic explorers of the future. NASA has an acute interest in the development of specialized ROVs, as new lessons learned on Earth can be applied to new environments and increasingly complex missions in the future of space exploration.

  20. Dimensionality of joint torques and muscle patterns for reaching.

    Muscle activities underlying many motor behaviors can be generated by a small number of basic activation patterns with specific features shared across movement conditions. Such low-dimensionality suggests that the central nervous system (CNS) relies on a modular organization to simplify control. However, the relationship between the dimensionality of muscle patterns and that of joint torques is not fixed, because of redundancy and non-linearity in mapping the former into the latter, and needs to be investigated. We compared the torques acting at four arm joints during fast reaching movements in different directions in the frontal and sagittal planes and the underlying muscle patterns. The dimensionality of the non-gravitational components of torques and muscle patterns in the spatial, temporal, and spatiotemporal domains was estimated by multidimensional decomposition techniques. The spatial organization of torques was captured by two or three generators, indicating that not all the available coordination patterns are employed by the CNS. A single temporal generator with a biphasic profile was identified, generalizing previous observations on a single plane. The number of spatiotemporal generators was equal to the product of the spatial and temporal dimensionalities and their organization was essentially synchronous. Muscle pattern dimensionalities were higher than torques dimensionalities but also higher than the minimum imposed by the inherent non-negativity of muscle activations. The spatiotemporal dimensionality of the muscle patterns was lower than the product of their spatial and temporal dimensionality, indicating the existence of specific asynchronous coordination patterns. Thus, the larger dimensionalities of the muscle patterns may be required for CNS to overcome the non-linearities of the musculoskeletal system and to flexibly generate endpoint trajectories with simple kinematic features using a limited number of building blocks.

  2. The Role of Absorption Cooling for Reaching Sustainable Energy Systems

    Energy Technology Data Exchange (ETDEWEB)

    Lindmark, Susanne

    2005-07-01

    This thesis focuses on the role and potential of absorption cooling in future energy systems. Two types of energy systems are investigated: a district energy system based on waste incineration and a distributed energy system with natural gas as fuel. In both cases, low temperature waste heat is used as driving energy for the absorption cooling. The main focus is to evaluate the absorption technology in an environmental perspective, in terms of reduced CO{sub 2} emissions. Economic evaluations are also performed. The reduced electricity when using absorption cooling instead of compression cooling is quantified and expressed as an increased net electrical yield. The results show that absorption cooling is an environmentally friendly way to produce cooling as it reduces the use of electrically driven cooling in the energy system and therefore also reduces global CO{sub 2} emissions. In the small-scale trigeneration system the electricity use is lowered with 84 % as compared to cooling production with compression chillers only. The CO{sub 2} emissions can be lowered to 45 CO{sub 2}/MWh{sub c} by using recoverable waste heat as driving heat for absorption chillers. However, the most cost effective cooling solution in a district energy system is a combination between absorption and compression cooling technologies according to the study. Absorption chillers have the potential to be suitable bottoming cycles for power production in distributed systems. Net electrical yields over 55 % may be reached in some cases with gas motors and absorption chillers. This small-scale system for cogeneration of power and cooling shows electrical efficiencies comparable to large-scale power plants and may contribute to reducing peak electricity demand associated with the cooling demand.

    The purpose of our study was to measure the sound level generated by selected commercially available cast saws. These levels were then compared with the level of everyday sounds and to accepted intensities by Safety Administrations to see whether the mandatory use of hearing protection should be recommended to prevent noise-induced hearing loss. We assessed the sound levels generated by the Quiet Cast Removal System (QCR; OrthoPediatrics Corp., Warsaw, IN), Stryker 986 Cast Vac (Stryker Corp.), and the Stryker 840 Cast Cutter (Stryker Corp.). The sound generated by these saws was measured with a sound level meter at the source and at 6, 12, and 36 inches. The sound level from each device was assessed both while operating alone and while cutting casts for a total of 3 repetitions at each of the distances tested and analyzed statistically. The maximal mean sound intensity of the Stryker 986 and Stryker 840 saws was 90.7 and 88.6 dBA at 36 inches, respectively while cutting a cast, whereas the QCR System produced 50.1 dBA at this distance. At 6 inches, the mean sound intensity was 99.4, 96.4, and 64.5 dBA for the Stryker 840, 986, and QCR, respectively. Statistically significant differences in sound intensity between Stryker and QCR saws were noted under all testing scenarios (Pnoise is common in orthopaedic clinics. Our study demonstrates sound levels from commercially available saws do not reach occupational hazards but are sufficiently high that practical methods to reduce intensity may be warranted.

  4. Spatial resolution of spontaneous accelerations in reaching tasks.

    Wininger, Michael; Kim, Nam-Hun; Craelius, William

    2009-01-05

    Reaching tasks are considered well-executed if they appear "smooth," a quality that is typically quantified by its opposite, jerk, the rate of change of acceleration. While jerk is a theoretically sound measure, its application to spastic individuals sometimes yields counter-intuitive results, and does not reveal motor impairment across the workspace. To more generally quantify spontaneous accelerative transients (SATs) within a movement, a pseudo-wavelet transform was devised that iteratively compared angular trajectories to a series of straight-line approximants. Cumulative linear fit errors were expressed in terms of flexion angle, yielding an SAT map of the entire motion. To compare SAT maps with traditional smoothness measures, two scalar indices were extracted from them: residual excursion deviation (RED), representing the integral over Deltatheta and the ratio of peak error to mean error (PEME) on the map. Fifteen subjects, including five subjects with chronic stroke performed elbow flexions throughout their entire ranges of motion, Deltatheta, at a comfortable pace with their arms supported in the transverse plane. Maps revealed that stroke subjects were significantly less coordinated than controls, as measured both by RED: 8.0+/-2.9 x 10(-3) versus 3.1+/-0.8 x 10(-3) and PEME: 6.6+/-0.9 versus 12.1+/-1.9, both P<0.001. Comparable jerk metrics, including integrated average jerk, did not report a significant performance deficit at the P<0.05 level. Map metrics for all subjects were independent of average velocity (correlation with theta : rho0.31), but jerk-based metrics for stroke subjects were spuriously co-variant with velocity rho=0.85, which may relate to the significantly higher mean arrest period ratio in stroke subjects (0.26+/-0.19 versus 0.09+/-0.08, P<0.001). We conclude that SAT maps provide reliable information on regional movement impairments at a wide range of proficiency levels.

    During goal-directed arm movements, the eyes, head, and arm are coordinated to look at and reach the target. We examined whether the expectancy of visual information about the target modifies Anticipatory Postural Adjustments (APAs). Ten standing subjects had to (1) move the eyes, head and arm, so as to reach, with both gaze and index-finger, a target of known position placed outside their visual field (Gaze-Reach); (2) look at the target while reaching it (Reach in Full Vision); (3) keep the gaze away until having touched it (Reach then Gaze) and (4) just Gaze without Reach the target. We recorded eye, head, right arm, and acromion kinematics, EMGs from upper- and lower-limb muscles, and forces exerted on the ground. In Gaze-Reach, two coordination strategies were found: when gaze preceded arm muscle recruitment (Gaze-first) and when the opposite occurred (Reach-first). APAs in acromion kinematics, leg muscles, and ground forces started significantly earlier in Gaze-first vs. Reach-first (mean time advance: 44.3 ± 8.9 ms), as it was in Reach in Full Vision vs. Reach then Gaze (39.5 ± 7.9 ms). The Gaze-first to Reach-first time-shift was similar to that between Reach in Full Vision and Reach then Gaze (p = 0.58). Moreover, Gaze without Reach data witnessed that the head-induced postural actions did not affect the APA onset in Gaze-first and Reach-first. In conclusion, in Gaze-first, the central control of posture considers visual information while planning the movement, like in Reach in Full Vision; while Reach-first is more similar to Reach then Gaze, where vision is not required.

  6. Technology Transfer, Reaching the Market for Geopressured-Geothermal Resources

    Technology transfer to the industrial sector for geopressured-geothermal technology has included diverse strategies, with successes and obstacles or roadblocks. Numerical data are tabulated in terms of response to the various strategies. Strategy categories include the following: feasibility studies and reports, consortium activities and proceedings, the Geothermal Resource Council, national and international meetings of the American Association of Petroleum Geologists, other societal and organizational meetings, and conferences, Department of Energy solicitation of interest in the Commerce Business Daily, industry peer review panels, and the Secretary's Technology Initiative. Additionally, the potential of a 12-page color brochure on the geopressured-geothermal resource, workshops, and cooperative research and development agreement (CRADA) is discussed. In conclusion, what is the best way to reach the market and what is the winning combination? All of the above strategies contribute to technology transfer and are needed in some combination for the desired success. The most successful strategy activities for bringing in the interest of the largest number of industries and the independents are the consortium meetings, one-on-one telephone calling, and consortium proceedings with information service followup. the most successful strategy activities for bringing in the interest and participation of ''majors'' are national and international peer reviewed papers at internationally recognized industry-related society meetings, and on-call presentations to specific companies. Why? Because quality is insured, major filtering has already taken place, and the integrity of the showcase is established. Thus, the focused strategy is reduced to a target of numbers (general public/minors/independents) versus quality (majors). The numerical results of the activities reflecting four years of technology transfer following the 15 year lead in the early phases

    Background Auditory hallucinations (eg, hearing voices) are relatively common and underreported false sensory experiences that may produce distress and impairment. A large proportion of those who experience auditory hallucinations go unidentified and untreated. Traditional engagement methods oftentimes fall short in reaching the diverse population of people who experience auditory hallucinations. Objective The objective of this proof-of-concept study was to examine the viability of leveraging Web-based social media as a method of engaging people who experience auditory hallucinations and to evaluate their attitudes toward using social media platforms as a resource for Web-based support and technology-based treatment. Methods We used Facebook advertisements to recruit individuals who experience auditory hallucinations to complete an 18-item Web-based survey focused on issues related to auditory hallucinations and technology use in American adults. We systematically tested multiple elements of the advertisement and survey layout including image selection, survey pagination, question ordering, and advertising targeting strategy. Each element was evaluated sequentially and the most cost-effective strategy was implemented in the subsequent steps, eventually deriving an optimized approach. Three open-ended question responses were analyzed using conventional inductive content analysis. Coded responses were quantified into binary codes, and frequencies were then calculated. Results Recruitment netted N=264 total sample over a 6-week period. Ninety-seven participants fully completed all measures at a total cost of $8.14 per participant across testing phases. Systematic adjustments to advertisement design, survey layout, and targeting strategies improved data quality and cost efficiency. People were willing to provide information on what triggered their auditory hallucinations along with strategies they use to cope, as well as provide suggestions to others who experience

    -cycle feedbacks, and also comparing against other model projections from the IPCC, our best estimate is that the A1FI emissions scenario would lead to a warming of 4°C relative to pre-industrial during the 2070s. If carbon-cycle feedbacks are stronger, which appears less likely but still credible, then 4°C warming could be reached by the early 2060s in projections that are consistent with the IPCC's 'likely range'.

    QSAR (Quantitative Structure Activity Relationship) models can be a valuable alternative method to replace or reduce animal test required by REACH. In particular, some endpoints such as bioconcentration factor (BCF) are easier to predict and many useful models have been already developed. In this paper we describe how to integrate two popular BCF models to obtain more reliable predictions. In particular, the herein presented integrated model relies on the predictions of two among the most used BCF models (CAESAR and Meylan), together with the Applicability Domain Index (ADI) provided by the software VEGA. Using a set of simple rules, the integrated model selects the most reliable and conservative predictions and discards possible outliers. In this way, for the prediction of the 851 compounds included in the ANTARES BCF dataset, the integrated model discloses a R{sup 2} (coefficient of determination) of 0.80, a RMSE (Root Mean Square Error) of 0.61 log units and a sensitivity of 76%, with a considerable improvement in respect to the CAESAR (R{sup 2} = 0.63; RMSE = 0.84 log units; sensitivity 55%) and Meylan (R{sup 2} = 0.66; RMSE = 0.77 log units; sensitivity 65%) without discarding too many predictions (118 out of 851). Importantly, considering solely the compounds within the new integrated ADI, the R{sup 2} increased to 0.92, and the sensitivity to 85%, with a RMSE of 0.44 log units. Finally, the use of properly set safety thresholds applied for monitoring the so called “suspicious” compounds, which are those chemicals predicted in proximity of the border normally accepted to discern non-bioaccumulative from bioaccumulative substances, permitted to obtain an integrated model with sensitivity equal to 100%. - Highlights: • Applying two independent QSAR models for bioconcentration factor increases the prediction. • The concordance of the models is an important component of the integration. • The measurement of the applicability domain improves the

    The effective placement of chemical squeeze treatments in heterogeneous wells and long reach horizontal wells has proved a significant challenge, with various factors including heterogeneity, crossflow and pressure gradients between otherwise non-communicating zones within the well, all contributing to an uneven placement of the scale squeeze treatment into the reservoir. Current methods to circumvent these problems often rely on extremely expensive coiled tubing operations, staged diversion (temporary shut off) treatments or by designing treatments to deliberately overdose some zones in order to gain placement in other (e.g. low permeability) zones. Moreover for deepwater sub sea horizontal wells the costs associated with ''spot'' treating along the length of horizontal wells by coil tubing tractor operations can often be prohibitively expensive. For other very near well bore treatments such as acid stimulation a number of self diverting strategies including gelled acid treatments, staged viscoelastic surfactant treatments and foams have been applied in field treatments with some success. However the properties which make such treatments applicable for acid stimulation may also make them inappropriate for bullhead scale squeeze treatments. Recent work by the current authors has however indicated the possible benefits of using modified injection fluids to aid uniform scale inhibitor placement in such wells in order to effect more even placement. In summary this paper will describe the various options available for achieving self diversion and describes the potential drawbacks associated with the viscous placement fluids commonly used for acid simulation techniques. In addition, various simulation packages commonly used for scale related calculations are reviewed and their limitations, primarily due to the inherent assumptions made and input parameters used, for modelling squeeze treatments using such modified fluids are described.

    2011-07-01

    Full Text Available Bibliotherapy, as a part of expressive therapy, involves the systematic use of books to help people cope with mental, physical, emotional, or social problems. It has been widely recognized as an approach that holds great promise in helping librarians to better address emotional, behavioural and socials concerns of various groups of people. The benefits of bibliotherapeutic services such as reading groups, expanded readers’ advisory, books-on-prescription and information-on-prescription services as well as various outreach programs are well documented in the library literature. On the other hand, health professionals who work in cooperation with educators and librarians share medical records on the healing and consoling power of books. The paper will explore the role of bibliotherapy in a library setting and identify particular bibliotherapeutic schemes to be used when serving people affected by HIV/AIDS. The paper will provide an overview of the library project developed to address educational and recreational needs of the African people living with HIV/AIDS. The project was successfully implemented at the Nkosi’s Haven Library in Johannesburg, South Africa in 2010. Although the project targeted all the residents of Nkosi’s Haven, the paper will focus mostly on the part of the program developed for children and young adults. The paper will identify psychological and social factors that affect the targeted group of children within the African environment. Particularly, it will highlight a negative effect that stigmatization around the disease has on the lives of the HIV-infected individuals and their families. Within this context, bibliotherapy is seen as an effective way of reaching out and breaking the isolation of people, especially children living with HIV/AIDS. The paper will describe specific activities strategically chosen for the bibliotherapy sessions to provide a channel through which the participants of the program could analyze

  13. Ulysses reaches maximum latitude over the Sun's northern pole

    Science.gov (United States)

    1995-08-01

    All operations and science experiments continue to go well and NASA's tracking facilities near Madrid and Goldstone, California, are monitoring the spacecraft 24 hours a day as manoeuvres are performed to keep Ulysses' radio antenna pointing toward the Earth. Launched in October 1990 aboard the space shuttle Discovery, the 370-kilogram spacecraft was designed to study the heliosphere - that region of space dominated by the solar wind -at all latitudes above and below the Sun's equatorial plane. These high latitude regions have never been explored before. Named after the legendary adventurer who journeyed to the "hidden" side of the Sun, Ulysses carries nine scientific instruments provided by research institutes in Europe and the United States to make detailed studies of solar wind, magnetic fields, energetic solar and cosmic ray particles, natural radio waves, and interplanetary dust and gas. In addition, a gamma- ray burst detector helps determine the source of the brightest cosmic gamma-ray bursts. In a permanent 6-year orbit about the Sun, the spacecraft is currently travelling at about 90,000 kilometers per hour with respect to the Sun. Having made its greatest northern excursion, Ulysses is now gradually descending in latitude. On 29 September 1995, the spacecraft will complete the northern polar pass and begin to travel back out to the orbit of Jupiter, reaching Jupiter's distance of about 800 million kilometers in April, 1998. Ulysses will then head back on its high latitude trajectory toward the Sun, returning first to the south polar regions in the year 2000, followed by a second flight over the north pole in 2001. Initial results from the climb to high northern latitudes have already confirmed a number of the findings from Ulysses' southern polar pass that took place last year. As expected, once the spacecraft moved away from the equatorial regions heading north, it became permanently immersed in fast solar wind from the northern polar cap. Another

    Since publication of the 1998 UNEP Assessment, there has been continued rapid expansion of the literature on UV-B radiation. Many measurements have demonstrated the inverse relationship between column ozone amount and UV radiation, and in a few cases long-term increases due to ozone decreases have been identified. The quantity, quality and availability of ground-based UV measurements relevant to assessing the environmental impacts of ozone changes continue to improve. Recent studies have contributed to delineating regional and temporal differences due to aerosols, clouds, and ozone. Improvements in radiative transfer modelling capability now enable more accurate characterization of clouds, snow-cover, and topographical effects. A standardized scale for reporting UV to the public has gained wide acceptance. There has been increased use of satellite data to estimate geographic variability and trends in UV. Progress has been made in assessing the utility of satellite retrievals of UV radiation by comparison with measurements at the Earth's surface. Global climatologies of UV radiation are now available on the Internet. Anthropogenic aerosols play a more important role in attenuating UV irradiances than has been assumed previously, and this will have implications for the accuracy of UV retrievals from satellite data. Progress has been made inferring historical levels of UV radiation using measurements of ozone (from satellites or from ground-based networks) in conjunction with measurements of total solar radiation obtained from extensive meteorological networks. We cannot yet be sure whether global ozone has reached a minimum. Atmospheric chlorine concentrations are beginning to decrease. However, bromine concentrations are still increasing. While these halogen concentrations remain high, the ozone layer remains vulnerable to further depletion from events such as volcanic eruptions that inject material into the stratosphere. Interactions between global warming and

    Dual visuomotor channel theory proposes that reaching depends on two neural pathways that extend from visual cortex (V1) to motor cortex via the parietal lobe. The Reach pathway directs the hand to the target's location and the Grasp pathway shapes the hand and digits for purchase. Sighted human participants integrate the Reach and the Grasp, but without vision they dissociate the movements to capitalize on tactile cues. They use a Reach with a relatively open hand to locate the target and then they use touch cues to shape the fingers to Grasp. After a V1 lesion, the rhesus monkey, Helen, learned to make near-normal visual discriminations based on size and brightness but displayed visual agnosia. She also learned to reach for food with her mouth and her hands. The present analysis of film of her reaching behavior shows that she dissociated the Reach and the Grasp, as do unsighted human participants reaching for a food target at a fixed location. Her rapid and direct Reach was made with an open hand and extended fingers to contact the food with the palm whereas her Grasp was initiated after she touched the food. She also visually fixated the target during the Reach and visually disengaged after target contact, as do sighted human participants. In contrast, Helen did integrate the Reach and the Grasp to take food from her mouth, demonstrating that she could integrate the movements using online tactile cues. The finding that extrastriate pathways can direct the hand toward extrinsic target properties (location) but not intrinsic target properties (size and shape) is discussed as a novel addition to dual visuomotor channel theory.

    1999-11-01

    In the United States, National Chemistry Week is November 7-13. (For more NCW information, go to http://www.acs.org/ncw/.) NCW's theme, celebrating polymers, is echoed in this issue (pages 1497-1501, 1512-1513, 1521-1540). Almost certainly there will be chemists in your area spending a great deal of their time on outreach activities for children and the general public during NCW. Chances are good that many Journal readers like you will be among them. And there are probably many more outreach programs that you or your acquaintances lead during the rest of the year. This month of NCW seems an appropriate time to reflect on the tremendous benefits that outreach programs provide. Early examples of outreach involved books, public lectures, and chemical demonstrations. In 1800 Count Rumford collaborated with influential Londoners to establish the Royal Institution as a means of providing lectures on science and technology to help working people to improve their lot. Humphry Davy, Michael Faraday, and many others continued the tradition. Faraday's own interest in science was sparked in part by Jane Marcet's book Conversations in Chemistry, whose friendly style made its contents accessible and fascinating to the young, highly intelligent bookbinder's apprentice. In the United States, Benjamin Silliman, first professor of chemistry at Yale, became widely known for his textbooks on geology and chemistry and for his ability as a popular lecturer. Silliman's lecture tours took him as far from New Haven as St. Louis and New Orleans. By the mid-1800s societies for the advancement of science and of chemistry were being set up in Europe. In 1876 American chemists who gathered at Priestley's grave in Northumberland, Pennsylvania, to commemorate the centennial of the discovery of oxygen saw the need for a permanent organization and founded the American Chemical Society. By the beginning of the 20th century these societies were supporting education and public awareness of science. The first issue of this Journal described an outreach effort to place portraits of great American chemists in schools throughout the country, and a 1925 article dealt with "Educating the Public in the Use of the Metric System". A search of the JCE Online Index reveals many articles about chemistry and the public, with the number per year increasing steadily. During the last decade, for example, there have been 16 articles whose titles include "outreach" and many more that describe programs and resources for the general public. Current outreach efforts include a much broader range of activities and media. Hands-on science has become very popular, but so has virtual science on the World Wide Web. A combination of the two, which is aimed at K-8 children, can be found at the ACS Education Division's WonderNet site (http://www.acs.org/wondernet/). For older children there is Your Virtual Chemistry Club (http://www.acs.org/vc2/). Many more ACS outreach materials are described at their Web site. Outreach activities described in this Journal include programs in which high school, college, or graduate students visit schools and work with children and teachers, events in which participants compete to carry out chemical tasks, programs aimed at women and minorities, van programs in which chemicals and instruments are transported throughout broad geographical areas to support teachers and students, chemistry summer camps, and many others. The International Chemistry Olympiad (see report on page 1480) involves large numbers of students and ACS local sectionsand more than 50 countries. Outreach to outreach leaders is provided by the Institute for Chemical Education, which distributes booklets that explain how to organize and carry out programs (http://ice.chem.wisc.edu/ice/). The concept that the public is interested in science and can benefit from learning about science has expanded far beyond what Count Rumford could have imagined. Today we have books, magazines, videos, television programs, museums, theme parks, Web sites, and many other venues that include science. However, I always have a twinge of disappointment when I look at the shelves in our local bookstore and find that there are far more titles in other sciences than in chemistry. Are other sciences inherently more interestingor their practitioners inherently more literate? I think not. Popularizing chemistry is more dependent on human interaction than is popularizing many other sciences. People deal with devices that approximate Newtonian physics every day. The stars, moon, and planets are there every night, and their vast number and regular motions inspire awe. Living systems are familiar to everyone, and we can observe their behavior and classify them. But chemistry is often hidden or complicated. Cooking food changes the food chemically, but both initial and final versions, like most other substances we encounter daily, are complicated mixtures. Chemists' atomic-scale models are not accessible to our senses. In order for chemistry not to be magic, someone needs to select simple, interesting, relevant examples, demonstrate them or help the average person work with them, and then relate those examples to everyday life. Participating in and supporting National Chemistry Week and other outreach programs is crucial to the health of our discipline. Without chemists who donate their time and expertise to helping people understand and become familiar with chemistry, our fascinating subject is likely to seem dullor even scary. During National Chemistry Week, and during every other week of the year, we should extend hearty thanks to the myriad chemists and teachers whose time, energy, and expertise contribute to helping the public recognize how important and interesting chemistry is.

  6. Generalization patterns for reach adaptation and proprioceptive recalibration differ after visuomotor learning

    Science.gov (United States)

    Cressman, Erin K.

    2015-01-01

    Visuomotor learning results in changes in both motor and sensory systems (Cressman EK, Henriques DY. J Neurophysiol 102: 3505–3518, 2009), such that reaches are adapted and sense of felt hand position recalibrated after reaching with altered visual feedback of the hand. Moreover, visuomotor learning has been shown to generalize such that reach adaptation achieved at a trained target location can influence reaches to novel target directions (Krakauer JW, Pine ZM, Ghilardi MF, Ghez C. J Neurosci 20: 8916–8924, 2000). We looked to determine whether proprioceptive recalibration also generalizes to novel locations. Moreover, we looked to establish the relationship between reach adaptation and changes in sense of felt hand position by determining whether proprioceptive recalibration generalizes to novel targets in a similar manner as reach adaptation. On training trials, subjects reached to a single target with aligned or misaligned cursor-hand feedback, in which the cursor was either rotated or scaled in extent relative to hand movement. After reach training, subjects reached to the training target and novel targets (including targets from a second start position) without visual feedback to assess generalization of reach adaptation. Subjects then performed a proprioceptive estimation task, in which they indicated the position of their hand relative to visual reference markers placed at similar locations as the trained and novel reach targets. Results indicated that shifts in hand position generalized across novel locations, independent of reach adaptation. Thus these distinct sensory and motor generalization patterns suggest that reach adaptation and proprioceptive recalibration arise from independent error signals and that changes in one system cannot guide adjustments in the other.

To examine this, a systematic literature search and meta-analyses were performed.

    Pandey, Achala; Agrawal, Rekha; Mandloi, Ravindra S.; Sarkar, Biswaroop

    2017-08-01

    This paper presents a new kind of adaptive reaching law for sliding mode control of Dynamic Voltage Restorer (DVR). Such an adaptive reaching law follows under-damped sinusoidal nature that causes the initial state to reach the sliding regime in extremely less time with negligible chattering. Moreover, it is robust in the sense the trajectory does not deviate from the sliding surface. This new approach is developed and successfully applied to DVR. The simulation results are presented that show its robustness.

  9. Does use of a virtual environment change reaching while standing in patients with traumatic brain injury?

    Although numerous virtual reality applications have been developed for sensorimotor retraining in neurologically impaired individuals, it is unclear whether the virtual environment (VE) changes motor performance, especially in patients with brain injuries. To address this question, the movement characteristics of forward arm reaches during standing were compared in physical and virtual environments, presented at different viewing angles. Fifteen patients with traumatic brain injuries (TBI) and 15 sex- and age-matched healthy individuals performed virtual reaches in a computer-generated courtyard with a flower-topped hedge. The hedge was projected on a flat screen and viewed in 3D format in 1 of 3 angles: 10° above horizon (resembling a real-world viewing angle), 50° above horizon, or 90° above horizon (directly overhead). Participants were instructed to reach with their dominant hand avatar and to touch the farthest flower possible without losing their balance or stepping. Virtual reaches were compared with reaches-to-point to a target in an equivalent physical environment. A set of kinematic parameters was used. Reaches by patients with TBI were characterized by shorter distances, lower peak velocities, and smaller postural displacements than reaches by control individuals. All participants reached ~9% farther in the VE presented at a 50° angle than they did in the physical environment. Arm displacement in the more natural 10° angle VE was reduced by the same 9-10% compared to physical reaches. Virtual reaches had smaller velocity peaks and took longer than physical reaches. The results suggest that visual perception in the VE differs from real-world perception and the performance of functional tasks (e.g., reaching while standing) can be changed in TBI patients, depending on the viewing angle. Accordingly, the viewing angle is a critical parameter that should be adjusted carefully to achieve maximal therapeutic effect during practice in the VE.

  10. Rapid On-Line Control to Reaching Is Preserved in Children With Congenital Spastic Hemiplegia: Evidence From Double-Step Reaching Performance.

    This study aimed to investigate the integrity of on-line control of reaching in congenital spastic hemiplegia in light of disparate evidence. Twelve children with and without spastic hemiplegia (11-17 years old) completed a double-step reaching task requiring them to reach and touch a target that remained stationary for most trials (viz nonjump trial) but unexpectedly displaced laterally at movement onset for a minority of trials (20%: known as jump trials). Although children with spastic hemiplegia were generally slower than age-matched controls, they could account for target perturbation at age-appropriate levels shown by a lack of interaction effect on movement time and nonsignificant group difference for time to reach trajectory correction on jump trials. Our data suggest that at a group level, on-line control of reaching may be age-appropriate in spastic hemiplegia. However, our data also highlight the need to experimentally acknowledge the considerable heterogeneity of the spastic hemiplegia population when investigating motor cognition. © The Author(s) 2014.

  13. The case for including reach as a key element of program theory.

    Montague, Steve; Porteous, Nancy L

    2013-02-01

    This paper suggests that there is a need to build reach in the logic models and results frameworks of public health initiatives. A lack of explicit thinking about reach in logic models can lead to problems such as narrow/constricted understanding of impacts chain, favoring of 'narrow and efficient' initiatives over 'wide and engaging' initiatives and biased thinking against equity considerations. An alternative approach described in this paper that explicitly considers reach demonstrates that an explicit description of reach in program theory and results logic depictions can improve equity in health and social systems.

    Movement preparation of both anticipatory postural adjustments (APAs) and goal directed movement during a standing reaching task in adults with chronic hemiparesis and healthy controls was investigated. Using a simple reaction time paradigm, while standing on two separate force platforms, subjects received a warning light cue to "get ready to reach" followed 2.5s later by an imperative light cue to "reach as quickly as possible" with the paretic arm (matched arm for controls) to touch a target in front of them for a total of 90 trials. In 30 of the reaching trials a loud acoustic stimulus (LAS) of 123 dB was randomly - -200, or 0ms relative to the "go" cue. APA (postural) responses were characterized by the onset and maximal posterior displacement of center of pressure (CoP) and onset/offset of electromyography (EMG) from tibialis anterior (TA), soleus (SOL), while reach was characterized by onset and maximal forward displacement of the reach hand and onset of the anterior (AD), biceps brachii (BB) and middle deltoid (MD). Subjects with stroke, demonstrated a marked reduction in the occurrence of the StartReact responses for both APA and forward reach at all LAS time points indicating movement preparation dysfunction. Movement execution during a cued reach showed significant delays in APA and reach onsets, significant reduction in the magnitude of APA (posterior CoP displacement) and reach excursion, and an increased latency between the APA and reach compared to controls. EMG activation patterns for the TA and SOL demonstrated co contraction compared to the temporally sequenced pattern of control subjects. When LAS was provided at the "go" there were earlier but not significant differences in APA onset latency compared to reaching without LAS and significant delays in reach onset latency when compared to control subjects with or without LAS. An early burst of EMG in biceps brachii muscles with a further delay of the reach onset compared to reaching without LAS may

    Full Text Available We have shown that when subjects reach with continuous, misaligned visual feedback of their hand, their reaches are adapted and proprioceptive sense of hand position is recalibrated to partially match the visual feedback (Salomonczyk et al., 2011. It is unclear if similar changes arise after reaching with visual feedback that is provided only at the end of the reach (i.e., terminal feedback, when there are shorter temporal intervals for subjects to experience concurrent visual and proprioceptive feedback. Subjects reached to targets with an aligned hand-cursor that provided visual feedback at the end of each reach movement across a 99-trial training block, and with a rotated cursor over 3 successive blocks of 99 trials each. After each block, no cursor reaches, to measure aftereffects, and felt hand positions were measured. Felt hand position was determined by having subjects indicate the position of their unseen hand relative to a reference marker. We found that subjects adapted their reaches following training with rotated terminal visual feedback, yet slightly less (i.e., reach aftereffects were smaller, than subjects from a previous study who experienced continuous visual feedback. Nonetheless, current subjects recalibrated their sense of felt hand position in the direction of the altered visual feedback, but this proprioceptive change increased incrementally over the three rotated training blocks. Final proprioceptive recalibration levels were comparable to our previous studies in which subjects performed the same task with continuous visual feedback. Thus, compared to reach training with continuous, but altered visual feedback, subjects who received terminal altered visual feedback of the hand produced significant but smaller reach aftereffects and similar changes in hand proprioception when given extra training. Taken together, results suggest that terminal feedback of the hand is sufficient to drive motor adaptation, and also

  17. Phenomena and characteristics of barrier river reaches in the middle and lower Yangtze River, China

    2017-06-01

    Alluvial river self-adjustment describes the mechanism whereby a river that was originally in an equilibrium state of sediment transport encounters some disturbance that destroys the balance and results in responses such as riverbed deformation. A systematic study of historical and recent aerial photographs and topographic maps in the Middle and Lower Reaches of the Yangtze River (MLYR) shows that river self-adjustment has the distinguishing feature of transferring from upstream to downstream, which may affect flood safety, waterway morphology, bank stability, and aquatic environmental safety over relatively long reaches downstream. As a result, it is necessary to take measures to control or block this transfer. Using the relationship of the occurrence time of channel adjustments between the upstream and downstream, 34 single-thread river reaches in the MLYR were classified into four types: corresponding, basically corresponding, basically not corresponding, not corresponding. The latter two types, because of their ability to prevent upstream channel adjustment from transferring downstream, are called barrier river reaches in this study. Statistics indicate that barrier river reaches are generally single thread and slightly curved, with a narrow and deep cross-sectional morphology, and without flow deflecting nodes in the upper and middle parts of reaches. Moreover, in the MLYR, barrier river reaches have a hydrogeometric coefficient of {}1.2‱, a silty clay content of the concave bank {>}{9.5}%, and a median diameter of the bed sediment {>}{0.158} mm. The barrier river reach mechanism lies in that can effectively centralise the planimetric position of the main stream from different upstream directions, meaning that no matter how the upper channel adjusts, the main stream shows little change, providing relatively stable inflow conditions for the lower reaches. Regarding river regulation, it is necessary to optimise the benefits of barrier river reaches; long river

    We investigated the seasonal dynamics of in-stream metabolism at the reach scale (∼ 150 m) of headwaters across contrasting geological sub-catchments: clay, Greensand, and Chalk of the upper River Avon (UK). Benthic metabolic activity was quantified by aquatic eddy co-variance while water column activity was assessed by bottle incubations. Seasonal dynamics across reaches were specific for the three types of geologies. During the spring, all reaches were net autotrophic, with rates of up to 290 mmol C m-2 d-1 in the clay reach. During the remaining seasons, the clay and Greensand reaches were net heterotrophic, with peak oxygen consumption of 206 mmol m-2 d-1 during the autumn, while the Chalk reach was net heterotrophic only in winter. Overall, the water column alone still contributed to ∼ 25% of the annual respiration and primary production in all reaches. Net ecosystem metabolism (NEM) across seasons and reaches followed a general linear relationship with increasing stream light availability. Sub-catchment specific NEM proved to be linearly related to the local hydrological connectivity, quantified as the ratio between base flow and stream discharge, and expressed on a timescale of 9 d on average. This timescale apparently represents the average period of hydrological imprint for carbon turnover within the reaches. Combining a general light response and sub-catchment specific base flow ratio provided a robust functional relationship for predicting NEM at the reach scale. The novel approach proposed in this study can help facilitate spatial and temporal upscaling of riverine metabolism that may be applicable to a broader spectrum of catchments.

    2012-08-01

    The wavelength division multiplexing-time division multiplexing (WDM-TDM) passive optical network (PON) using reflective semiconductor optical amplifier (RSOA)-based colorless optical networking units (ONUs) is considered as a promising candidate for the realization of fiber-to-the-home (FTTH). And this architecture is actively considered by Industrial Technology Research Institute (ITRI) for the realization of FTTH in Taiwan. However, different fiber distances and optical components would introduce different power budgets to different ONUs in the PON. Besides, due to the aging of optical transmitter (Tx), the power decay of the distributed optical carrier from the central office (CO) could also reduce the injection power into each ONU. The situation will be more severe in the long-reach (LR) PON, which is considered as an option for the future access. In this work, we investigate a WDM-TDM PON using RSOA-based ONU for upstream data rate adjustment depending on different continuous wave (CW) injection powers. Both standard-reach (25 km) and LR (100 km) transmissions are evaluated. Moreover, a detail analysis of the upstream signal bit-error rate (BER) performances at different injection powers, upstream data rates, PON split-ratios under stand-reach and long-reach is presented.

  12. Spatiotemporal distribution of location and object effects in reach-to-grasp kinematics

    Science.gov (United States)

    Rouse, Adam G.

    2015-01-01

    In reaching to grasp an object, the arm transports the hand to the intended location as the hand shapes to grasp the object. Prior studies that tracked arm endpoint and grip aperture have shown that reaching and grasping, while proceeding in parallel, are interdependent to some degree. Other studies of reaching and grasping that have examined the joint angles of all five digits as the hand shapes to grasp various objects have not tracked the joint angles of the arm as well. We, therefore, examined 22 joint angles from the shoulder to the five digits as monkeys reached, grasped, and manipulated in a task that dissociated location and object. We quantified the extent to which each angle varied depending on location, on object, and on their interaction, all as a function of time. Although joint angles varied depending on both location and object beginning early in the movement, an early phase of location effects in joint angles from the shoulder to the digits was followed by a later phase in which object effects predominated at all joint angles distal to the shoulder. Interaction effects were relatively small throughout the reach-to-grasp. Whereas reach trajectory was influenced substantially by the object, grasp shape was comparatively invariant to location. Our observations suggest that neural control of reach-to-grasp may occur largely in two sequential phases: the first determining the location to which the arm transports the hand, and the second shaping the entire upper extremity to grasp and manipulate the object.

    2004-06-01

    To investigate if a single massage of the hamstring muscle group would alter the performance of the sit and reach test. Before treatment, each of 11 male subjects performed the sit and reach test. The treatment consisted of either massage of the hamstring muscle group (both legs, total time about 15 minutes) or supine rest with no massage. Performance of the sit and reach test was repeated after treatment. Each subject returned the subsequent week to perform the tests again, receiving the alternative treatment relative to their initial visit. Mean percentage changes in sit and reach scores after treatment were calculated for the massage and no massage treatments, and analysed using Student's t tests. Mean (SD) percentage changes in sit and reach scores after massage and no massage were small (6.0 (4.3)% and 4.6 (4.8)% respectively) and not significantly different for subjects with relatively high (15 cm and above) values before treatment. Mean percentage changes in sit and reach scores for subjects with relatively low values before treatment (below 15 cm) were large (18.2 (8.2)% and 15.5 (16.2)% respectively), but no significant differences were found between the massage and no massage groups. A single massage of the hamstring muscle group was not associated with any significant increase in sit and reach performance immediately after treatment in physically active young men.

    We previously showed that anisometropic amblyopia affects the programming and execution of saccades and reaching movements. In our current study, we investigated whether these amblyopia-related changes simply are due to a reduction in visual acuity alone by inducing artificial blur in one eye in visually-normal participants. Twelve visually-normal participants performed saccades and reach-to-touch movements to targets presented on a computer screen during binocular and monocular viewing. A contact lens was used to blur the vision of one eye to a mean acuity level of 20/50. Saccades and reaching kinematics were compared before blur, immediately after blur, and 5 hours after blur was induced. The 5 hours after blur kinematic data from visually-normal participants also were compared to those from 12 patients with anisometropic amblyopia who had comparable acuity in the amblyopic eye. Primary saccades (latency, amplitude, peak velocity), reaching movements (reaction time, movement time, peak acceleration, duration of the acceleration phase), and eye-hand coordination (saccade-to-reach planning interval, saccade-to-reach peak velocity interval) were not affected by induced monocular blur in visually-normal participants, either immediately or 5 hours after blur. Compared to visually-normal participants after 5 hours of blur, patients with anisometropic amblyopia had significantly longer and more variable saccade latency during amblyopic eye viewing, lower peak acceleration, and a longer acceleration phase during reaching, and a different temporal pattern of eye-hand coordination. Artificially-induced monocular blur in visually-normal participants did not affect saccades, reaching movements, and eye-hand coordination during a simple reach-to-touch task even after a period of blur exposure. In contrast, patients with anisometropic amblyopia demonstrated significantly different kinematics while performing the same task. These results indicate that loss of visual acuity

    Optic ataxia is a high order deficit in reaching to visual goals that occurs with posterior parietal cortex (PPC) lesions. It is a component of Balint’s syndrome that also includes attentional and gaze disorders. Aspects of optic ataxia are misreaching in the contralesional visual field, difficulty preshaping the hand for grasping, and an inability to correct reaches online. Recent research in non-human primates (NHPs) suggests that many aspects of Balint’s syndrome and optic ataxia are a result of damage to specific functional modules for reaching, saccades, grasp, attention, and state estimation. The deficits from large lesions in humans are likely composite effects from damage to combinations of these functional modules. Interactions between these modules, either within posterior parietal cortex or downstream within frontal cortex, may account for more complex behaviors such as hand-eye coordination and reach-to-grasp.

    The objective was to estimate the reliability and criterion-related validity of the Jump-and-Reach Test for the assessment of squat, countermovement, and drop jump performance of 32 male Brazilian professional volleyball players. Performance of squat, countermovement, and drop jumps with different dropping heights was assessed on the Jump-and-Reach Test and the measurement of flight time, then compared across different jump trials. The very high reliability coefficients of both assessment methods and the lower correlation coefficients between scores on the assessments indicate a very high consistency of each method but only moderate covariation, which means that they measure partly different items. As a consequence, the Jump-and-Reach Test has good ecological validity in situations when reaching height during the flight phase is critical for performance (e.g., basketball and volleyball) but only limited accuracy for the assessment of vertical impulse production with different jump techniques and conditions.

    Robot-mediated therapy (RMT) has been a very dynamic area of research in recent years. Robotics devices are in fact capable to quantify the performances of a rehabilitation task in treatments of several disorders of the arm and the shoulder of various central and peripheral etiology. Different systems for robot-aided neuro-rehabilitation are available for upper limb rehabilitation but the biomechanical parameters proposed until today, to evaluate the quality of the movement, are related to the specific robot used and to the type of exercise performed. Besides, none study indicated a standardized quantitative evaluation of robot assisted upper arm reaching movements, so the RMT is still far to be considered a standardised tool. In this paper a quantitative kinematic assessment of robot assisted upper arm reaching movements, considering also the effect of gravity on the quality of the movements, is proposed. We studied a group of 10 healthy subjects and results indicate that our advised protocol can be useful for characterising normal pattern in reaching movements.

    The rapid development of multiple national geospatial datasets related to topography, hydrology, and environmental characteristics in the past decade have provided new opportunities for the refinement of hydropower resource potential from undeveloped stream-reaches. Through 2011 to 2013, the Oak Ridge National Laboratory (ORNL) was tasked by the Department of Energy (DOE) Water Power Program to evaluate the new stream-reach development (NSD) resource potential for more than 3 million US streams. A methodology was designed that contains three main components: (1) identification of stream-reaches with high energy density, (2) topographical analysis of stream-reaches to estimate inundated surface area and reservoir storage, and (3) environmental attribution to spatially join information related to the natural ecological systems, social and cultural settings, policies, management, and legal constraints to stream-reaches of energy potential. An initial report on methodology (Hadjerioua et al., 2013) was later reviewed and revised based on the comments gathered from two peer review workshops. After implementing the assessment across the entire United States, major findings were summarized in this final report. The estimated NSD capacity and generation, including both higher-energy-density (>1 MW per reach) and lower-energy-density (<1 MW per reach) stream-reaches is 84.7 GW, around the same size as the existing US conventional hydropower nameplate capacity (79.5 GW; NHAAP, 2013). In terms of energy, the total undeveloped NSD generation is estimated to be 460 TWh/year, around 169% of average 2002 2011 net annual generation from existing conventional hydropower plants (272 TWh/year; EIA, 2013). Given the run-of-river assumption, NSD stream-reaches have higher capacity factors (53 71%), especially compared with conventional larger-storage peaking-operation projects that usually have capacity factors of around 30%. The highest potential is identified in the Pacific Northwest

    McMurdo dry valleys of Antarctica represent the largest of the ice-free areas on the Antarctic continent, containing glaciers, meltwater streams, and closed basin lakes. Previous geochemical studies of dry valley streams and lakes have addressed chemical weathering reactions of hyporheic substrate and geochemical evolution of dry valley surface waters. We examine cation transport and exchange reactions during a stream tracer experiment in a dry valley glacial meltwater stream. The injection solution was composed of dissolved Li+, Na+, K+, and Cl-. Chloride behaved conservatively in this stream, but Li+, Na+, and K+ were reactive to varying degrees. Mass balance analysis indicates that relative to Cl-, Li+ and K+ were taken up in downstream transport and Na+ was released. Simulations of conservative and reactive (first-order uptake or generation) solute transport were made with the OTIS (one-dimensional solute transport with inflow and storage) model. Among the four experimental reaches of Green Creek, solute transport simulations reveal that Li+ was removed from stream water in all four reaches, K+ was released in two reaches, taken up in one reach, and Na+ was released in all four reaches. Hyporheic sediments appear to be variable with uptake of Li+ in two reaches, uptake of K+ in one reach, release of K+ in two reaches, and uptake of Na+ in one reach. Mass balances of the conservative and reactive simulations show that from 1.05 to 2.19 moles of Li+ was adsorbed per reach, but less than 0.3 moles of K+ and less than 0.9 moles of Na+ were released per reach. This suggests that either (1) exchange of another ion which was not analyzed in this experiment or (2) that both ion exchange and sorption control inorganic solute transport. The elevated cation concentrations introduced during the experiment are typical of initial flows in each flow season, which flush accumulated dry salts from the streambed. We propose that the bed sediments (which compose the hyporheic

  17. Multimodal decoding and congruent sensory information enhance reaching performance in subjects with cervical spinal cord injury

    Full Text Available Cervical spinal cord injury (SCI paralyzes muscles of the hand and arm, making it difficult to perform activities of daily living. Restoring the ability to reach can dramatically improve quality of life for people with cervical SCI. Any reaching system requires a user interface to decode parameters of an intended reach, such as trajectory and target. A challenge in developing such decoders is that often few physiological signals related to the intended reach remain under voluntary control, especially in patients with high cervical injuries. Furthermore, the decoding problem changes when the user is controlling the motion of their limb, as opposed to an external device. The purpose of this study was to investigate the benefits of combining disparate signal sources to control reach in people with a range of impairments, and to consider the effect of two feedback approaches. Subjects with cervical SCI performed robot-assisted reaching, controlling trajectories with either shoulder electromyograms (EMGs or EMGs combined with gaze. We then evaluated how reaching performance was influenced by task-related sensory feedback, testing the EMG-only decoder in two conditions. The first involved moving the arm with the robot, providing congruent sensory feedback through their remaining sense of proprioception. In the second, the subjects moved the robot without the arm attached, as in applications that control external devices. We found that the multimodal decoding algorithm worked well for all subjects, enabling them to perform straight, accurate reaches. The inclusion of gaze information, used to estimate target location, was especially important for the most impaired subjects. In the absence of gaze information, congruent sensory feedback improved performance. These results highlight the importance of proprioceptive feedback, and suggest that multi-modal decoders are likely to be most beneficial for highly impaired subjects and in tasks where such

    Full Text Available Background: Among health care workers the highest level of work related back injuries are more affected in nurses. There were many studies done to assess low back pain by using different tools. So this study aimed to identify the prevalence low back pain disability among female nursing professionals and the association between BMI, functional reach test and low back pain, so that a better tool can be used during the clinical examination for the betterment of the patient. The objective of the study is to identify the prevalence of low back pain disability, the association of Low Back Pain(LBP with BMI and functional reach test among female nursing professionals. Methods: A total of 256 subjects were assessed for disability due to back pain using OswestryLBP Disability Questionnaire and the prevalence of disability was determined. The sit and reach test, forward reach test and their BMI were calculated for those who had a disability score of 20 and above (n=87. Results: Data was analyzed using Pearson’s correlation.The study result showed a significant correlation (p=0.03 of sit and reach test with low back pain disability scores. There was a negative correlationseen among BMI and LBP disability score forward reach test and LBP disability score, and BMI and no low back pain disability score. Conclusion: The prevalence of LBP disability among nursing professionals was 33.9%. This study suggest that sit and reach test can be used as an indicator of low back pain. Whereas BMI and forward reach test do not indicate low back pain.
