    Intercalation of Hydrotalcites with Hexacyanoferrate(II) and (III)-a ThermoRaman Spectroscopic Study

    Raman spectroscopy using a hot stage indicates that the intercalation of hexacyanoferrate(II) and (III) in the interlayer space of a Mg,Al hydrotalcites leads to layered solids where the intercalated species is both hexacyanoferrate(II) and (III). Raman spectroscopy shows that depending on the oxidation state of the initial hexacyanoferrate partial oxidation and reduction takes place upon intercalation. For the hexacyanoferrate(III) some partial reduction occurs during synthesis. The symmetry of the hexacyanoferrate decreases from Oh existing for the free anions to D3d in the hexacyanoferrate interlayered hydrotalcite complexes. Hot stage Raman spectroscopy reveals the oxidation of the hexacyanoferrate(II) to hexacyanoferrate(III) in the hydrotalcite interlayer with the removal of the cyanide anions above 250 °C. Thermal treatment causes the loss of CN ions through the observation of a band at 2080 cm-1. The hexacyanoferrate (III) interlayered Mg,Al hydrotalcites decomposes above 150 °C

    Perfectionism In Obsessive-Compulsive Disorder Patients

    Considerable theory and anecdotal evidence has suggested that patients with Obsessive-Compulsive Disorder (OCD) are more perfectionistic. Evidence with non-clinical populations supports this hypothesis. However, no data are available on levels of perfectionism among patients diagnosed with OCD. The present study extends findings on perfectionism and OCD by comparing perfectionism levels of OCD-diagnosed patients with those of non-patients and a group of patients diagnosed with panic disorder with agoraphobia (PDA). As predicted, patients with OCD had significantly elevated scores on Total Perfectionism, Concern Over Mistakes, and Doubts About Actions compared to non-patient controls. However, they did not differ from patients with PDA on Total Perfectionism or Concern Over Mistakes. Patients with OCD did have higher Doubts About Actions scores than those with PDA. The implications for the role of perfectionism in OCD and other anxiety disorders are discussed

    The Economic Impact of Non-Profit Arts Organizations in Nebraska, 1976-1977

    Get PDF
    What are the arts worth to Nebraska? Until recently no information has been available to answer that question. The arts provide an important cultural contribution, but they also support the economy by employing people, renting buildings, and purchasing supplies and services. The intangible attributes of artistic endeavors are commonly recognized. Economic contributions, however, have received little attention

    A comparison of cognitive restructuring and thought listing for excessive acquiring in hoarding disorder

    Get PDF
    Excessive acquiring is a common symptom of hoarding disorder (HD). Little is known about subjective distress associated with acquiring in HD. The present study examined acquiring- related distress and reactions to cognitive restructuring (CR) in 92 individuals with HD and 66 community control (CC) participants. All participants identified an item of interest at a high-risk acquiring location and then decided whether or not to acquire the item. HD participants completed the acquiring task while receiving a CR-based intervention or a thought-listing (TL) control condition. Results showed that HD participants reported more severe distress and greater urges to acquire the item of interest than did CC participants. Nevertheless, subjective distress decreased in both groups following the acquiring task. There were no differences in acquiring- related distress between the CR and TL conditions. The findings indicate that subjective distress may decrease after relatively short periods of time in individuals with HD, but that a single session of CR may not alleviate acquiring-related distress in HD participants.R01 MH068007 - NIMH NIH HHS; R01 MH068008 - NIMH NIH HHSAccepted manuscrip

    Comparison of Object and Animal Hoarding

    Get PDF
    Recent research has highlighted the prevalence and harmful consequences of hoarding,1 and investigators have proposed inclusion of hoarding disorder in DSM-5.2 An unanswered question about the proposed disorder is whether people who hoard animals would meet diagnostic criteria for it. This article discusses the similarities and differences between object and animal hoarding. People who hoard animals appear to meet the basic diagnostic criteria for hoarding disorder. Their homes are cluttered, disorganized, and dysfunctional. They have great difficulty relinquishing animals to people who can more adequately care for them, and they form intense attachments (urges to save) that result in significant impairment. However, they differ from people who hoard objects in several ways. These differences are significant enough to warrant comment in the text description accompanying the diagnostic criteria and consideration as a subtype of hoarding disorder. More research is necessary to determine the exact relationship between object and animal hoarding. © 2011 Wiley-Liss, Inc

    Hoarding By Elderly People

    Get PDF
    Although hoarding has been studied in adults, little is known about problems of hoarding by elderly people. This study used a structured telephone interview with elder services providers to investigate hoarding behaviors in relation to functional impairment, cognitive deficits, and physical and psychological conditions in 62 elderly clients. Most elderly hoarders were female, unmarried, and lived alone. Extensive clutter was associated with significant impairment, interfering with basic hygiene, and posing a serious physical threat for many elderly clients. Clients were rarely insightful about their collecting and often resisted change, rendering interventions generally ineffective. Never-married status was associated with more severe hoarding and greater impairment and possibly with worse outcomes of intervention efforts. Health and mental health implications of hoarding by elderly people and implications for treatment are discussed

    A Brief Interview for Assessing Compulsive Hoarding: The Hoarding Rating Scale-Interview

    Get PDF
    This article describes the development and validation of the Hoarding Rating Scale-Interview (HRS-I), a brief (5-10 min) five-item semi-structured interview that assesses the features of compulsive hoarding (clutter, difficulty discarding, acquisition, distress and impairment). Trained interviewers administered the HRS-I to 136 adults (73 compulsive hoarding, 19 OCD, 44 non-clinical controls) along with a battery of self-report measures. An initial assessment was conducted in the clinic, and a second assessment was conducted in participants\u27 homes. The HRS-I showed high internal consistency and reliability across time and context. The HRS-I clearly differentiated hoarding and non-hoarding participants, and was strongly associated with other measures of hoarding. It is concluded that the HRS-I is a promising measure for determining the presence and severity of compulsive hoarding
