Although much of the social science literature supports the importance of community assets for success in many policy areas, these assets are often overlooked when selecting communities for new infrastructure facilities. Extensive collaboration is crucial for the success of environmental and economic projects, yet it often is not adequately addressed when making siting decisions for new projects. This article develops a social asset framework that includes social, creative, and human capital to inform site-selection decisions...

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...

This study aimed to characterize the sociodemographic profile of animal hoarders in a southern city of Brazil. In addition, it aimed to propose Animal Hoarding Disorder as a new nosological category, distinct from Hoarding Disorder. Thirty-three individuals with Animal Hoarding Disorder, 73% female and 60% elderly, composed the sample. The average age of the sample was 61.39 years (SD = 12.69) and the average period that individuals hoarded or lived with a large number of animals was 23.09 years (SD = 15.98...

The lateral hypothalamus is known to drive food consumption during periods of hunger. A new study suggests that the lateral hypothalamus may also participate in the formation and storage of memories about events in the environment that predict the availability of food.

Mary E Dozier, Catherine R Ayers
This article will review the evidence of various proposed factors that contribute to the onset and maintenance of hoarding disorder (HD). Data suggests that hoarding is a chronic condition that starts early in life and does not remit if left untreated. There is emerging evidence that a number of factors contribute to the expression of HD symptoms, including genetics, neurocognitive functioning, attachments to possessions, beliefs, avoidance, personality factors, and life events. The extent to which each etiological factor uniquely contributes to hoarding is still unknown...

We describe clinical and biomarker findings in an index patient with the onset of Alzheimer's disease (AD) symptoms at age 57 and a family history consistent with an autosomal dominant pattern of inheritance. She had the atypical early features of visual agnosia and prosopagnosia followed by hoarding behavior and Parkinsonism. Structural MRI revealed global atrophy that was most severe in the lateral temporal lobes and insular cortex bilaterally. CSF biomarker assessment showed Aβ42, p-tau181, and total tau levels consistent with AD...

Can Kabadayi, Mathias Osvath
The ability to flexibly plan for events outside of the current sensory scope is at the core of being human and is crucial to our everyday lives and society. Studies on apes have shaped a belief that this ability evolved within the hominid lineage. Corvids, however, have shown evidence of planning their food hoarding, although this has been suggested to reflect a specific caching adaptation rather than domain-general planning. Here, we show that ravens plan for events unrelated to caching-tool-use and bartering-with delays of up to 17 hours, exert self-control, and consider temporal distance to future events...

Hoarding disorder is characterized by a persistent difficulty discarding items, the desire to save items to avoid negative feelings associated with discarding them, significant accumulation of possessions that clutter active living areas and significant distress or impairment in areas of functioning. We present a case of a 52-year-old married man who was referred to the psychiatry department for collecting various objects that were deposited unorganized in the patient's house. He reported to get anxious when someone else discarded some of these items...

Scatter-hoarding behavior of granivorous rodents plays an important role in seed dispersal and seedling regeneration of trees, as well as the evolution of several well-known mutualisms between trees and rodents in forest ecosystems. Because it is difficult to identify seed hoarders and pilferers under field conditions by traditional methods, the full costs incurred and benefits accrued by scatter-hoarding have not been fully evaluated in most systems. By using infrared radiation camera tracking and seed tagging, we investigated the comprehensive benefits and losses of scatter-hoarded seeds (Camellia oleifera) for three sympatric rodent species (Apodemus draco, Niviventer confucianus and Leopoldamys edwardsi) in a subtropical forest of Southwest China during 2013 through 2015...

L Kalogeraki, I Michopoulos
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...

Ke Deng, Wei Liu, De-Hua Wang
Animals often interact non-randomly with conspecifics, and association preferences can differ across life-history stages to maximize individuals' fitness. Mongolian gerbils (Meriones unguiculatus) are a social rodent that live in highly seasonal habitats and display seasonal fluctuations in population density, growth rate and the size of overlapped home ranges. Nevertheless, whether gerbils modify their social relationships at different life-history stages remains unknown. Here, we used social network analysis to examine whether social associations differ between the sexes and between life-history stages in a wild population of Mongolian gerbils...

Current research to explore genetic susceptibility factors in obsessive-compulsive disorder (OCD) has resulted in the tentative identification of a small number of genes. However, findings have not been readily replicated. It is now broadly accepted that a major limitation to this work is the heterogeneous nature of this disorder, and that an approach incorporating OCD symptom dimensions in a quantitative manner may be more successful in identifying both common as well as dimension-specific vulnerability genetic factors...

The aims of this study were to assess the seasonal population dynamics and evaluate the performance of Apis mellifera jemenitica (local bee) and introduced hybrid honeybee colonies in the lowlands and highlands of southwestern Saudi Arabia. Data regarding the performance and population dynamics parameters such as brood and adult bee population, amounts of stored pollen and nectar were gathered from the two races (25 colonies of each) for one year (April 2013 through March 2014), and statistically tested. The results indicated that at low lands, local bee colonies maintained relatively high brood and adult bee populations (P < 0...

Diogenes syndrome refers to the combination of extreme self-neglect and excessive collecting with clutter and squalor, which is often present in patients with dementia. Diogenes syndrome may be particularly common in behavioral variant frontotemporal dementia (bvFTD), and the investigation of these patients may help clarify the nature of this syndrome. We describe 5 patients with bvFTD who exhibited a decline in self-care accompanied by hoarding behaviors. These patients, and a review of the literature, suggest a combination of frontal lobe disturbances: loss of insight or self-awareness with a failure to clean up or discard, a general compulsive drive, and an innate impulse to take environmental items...

BACKGROUND: Twin studies of hoarding symptoms indicate low to moderate heritability during adolescence and considerably higher heritability in older samples, suggesting dynamic developmental etiological effects. The aim of the current study was to estimate the relative contribution of additive genetic and environmental effects to hoarding symptoms during adolescence and young adulthood and to estimate the sources of stability and change of hoarding symptoms during adolescence. METHODS: Univariate model-fitting was conducted in three cohorts of twins aged 15 (n = 7,905), 18 (n = 2,495) and 20-28 (n = 6,218)...

BACKGROUND: The unique phenotypic and genetic aspects of obsessive-compulsive (OCD) and attention-deficit/hyperactivity disorder (ADHD) among individuals with Tourette syndrome (TS) are not well characterized. Here, we examine symptom patterns and heritability of OCD and ADHD in TS families. METHOD: OCD and ADHD symptom patterns were examined in TS patients and their family members (N = 3494) using exploratory factor analyses (EFA) for OCD and ADHD symptoms separately, followed by latent class analyses (LCA) of the resulting OCD and ADHD factor sum scores jointly; heritability and clinical relevance of the resulting factors and classes were assessed...

We tested the hypothesis that the effects of food restriction on behavioral motivation are mediated by one or both of the RFamide peptides, RFamide-related peptide-3 (RFRP-3) and kisspeptin (Kp) in female Syrian hamsters (Mesocricetus auratus). Female hamsters fed ad libitum and given a choice between food and adult male hamsters are highly motivated to visit males instead of food on all four days of the estrous cycle, but after 8days of mild food restriction (75% of ad libitum intake) they shift their preference toward food every day of the estrous cycle until the day of estrus, when they shift their preference back toward the males...

Persistent school segregation may allow advantaged groups to hoard educational opportunities and consign minority students to lower-quality educational experiences. Although minority students are concentrated in low-achieving schools, relatively little previous research directly links segregation to measures of school quality based on student achievement growth, which more plausibly reflect learning opportunities. Using a dataset of public elementary schools in California, this study provides the first analysis detailing the distribution of a growth-based measure of school quality using standard inequality indices, allowing disparities to be decomposed across geographic and organizational scales...

Tanja Margrethe Gjerlev Andersen, Per Hove Thomsen
In this case report hoarding disorder is described in a 12-year-old boy who suffered from obsessive collection of things. The disorder is a separate diagnostic entity in DSM-5, and it will probably be a separate disorder in ICD-11 called hoarding disorder. The disorder is generally considered difficult to treat, but this case report describes significant reduction in hoarding symptoms on cognitive behavioural therapy and treatment with selective serotonin reuptake inhibitors.
