Perfluoroalkyl chemicals (PFCs) have been used as surfactants and stain repellants in a variety of consumer products for more than 50years and there is growing concern regarding their persistence and toxicity. Human exposure to these chemicals is essentially universal in North America and researchers have linked them to a variety of health problems ranging from higher rates of cancer, to developmental and reproductive problems, and higher cholesterol levels. Major exposure pathways are food and water ingestion, dust ingestion via hand to mouth transfer. In an effort to assess residential exposure, the Wisconsin Department of Health Services tested vacuum cleaner contents from thirty-nine homes for 16 perflouroalkyl chemicals. PFOS, PFOA, PFHxS, PFHpA and PFNA were found in all of the vacuum dust samples and dust from eight homes contained all 16 PFCs included in our analysis. The most commonly detected compounds were perfluorooctanesulfonate (PFOS), perfluorohexanesulfonate (PFHxS) and perfluorooctanoic acid (PFOA) which together made up 70% of the total PFC residues in dust from these homes. Summed PFC concentrations in these dust samples ranged from 70 to 2513ng/g (median 280ng/g). Our investigation suggests that these chemicals may be ubiquitous contaminants in US homes.

A new technical tip for the improvement of the arthroscopic treatment of symptomatic calcifying tendinitis is described. Arthroscopic excision of calcifying tendonitis may result with multiple minute calcific debris in the subacromial bursa, causing severe post operative pain due to chemical irritation of the bursa. We suggest the use of a bladeless shaver barrel as a "Hoover" (vacuum cleaner) for arthroscopic clearance of these miniature calcific debris from the subacromial space after resection of the major deposits. The use of this technique resulted in good clinical outcome with improved post operative pain.

Four commercially available robotic vacuum cleaners were assessed for sampling efficiency of wet disseminated Bacillus atrophaeus spores on carpet, Polyvinyl Chloride (PVC) and laminate flooring. Furthermore, their operability was evaluated and decontamination efficiency of one robot was assessed using a sodium hypochlorite solution. In an environmental chamber, robots self-navigated around 4 m 2 of flooring containing a single contaminated 0.25 m 2 tile (ca. 10 4 spores per cm 2 ). Contamination levels at pre-determined locations were assessed by macrofoam swabs (PVC and laminate) or water soluble tape (carpet), before and after sampling. Robots were dismantled post-sampling and spore recoveries assessed. Aerosol contamination was also measured during sampling. Robot sampling efficiencies were variable, however, robots recovered most spores from laminate (up to 17.1%), then PVC, and lastly carpet. All robots spread contamination from the 'hotspot' (all robots spread < 0.6% of the contamination to other areas) and became surface contaminated. Spores were detected at low levels during air sampling (<5.6 spores l -1 ). Liquid decontamination inactivated 99.1% of spores from PVC. Robotic vacuum cleaners show promise for both sampling and initial decontamination of indoor flooring. In the event of a bioterror incident, e.g. deliberate release of Bacillus anthracis spores, areas require sampling to determine the magnitude and extent of contamination, and to establish decontamination efficacy. In this study we investigate robotic sampling methods against high concentrations of bacterial spores applied by wet deposition to different floorings, contamination spread to other areas, potential transfer of spores to the operators and assessment of a wet vacuum robot for spore inactivation. The robots' usability was evaluated and how they can be employed in real life scenarios. This will help to reduce the economic cost of sampling and the risk to sampling/decontamination teams

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are shown to be globally distributed, environmentally persistent and bioaccumulative. Although there is evidence that these compounds exist in the serum of non-occupationally exposed humans, the pathways leading to the presence of PFOS and PFOA are not well characterized. The concentrations of PFOS and PFOA in the vacuum cleaner dust collected in Japanese homes were measured. The compounds were detected in all the dust samples and the ranges were 11-2500 ng g(-1) for PFOS and 69-3700 ng g(-1) for PFOA. It was ascertained that PFOS and PFOA were present in the dust in homes, and that the absorption of the dust could be one of the exposure pathways of the PFOS and PFOA to humans. With regard to risk management, it is important to consider the usage of PFOS and PFOA in the indoor environment in order to avoid further pollution.

Enticed by the punschrulle: Preliminary investigation of the Seve Nappe Complex's incorporation into the Scandinavian Caledonides via 'vacuum-cleaner' exhumation.

Recent discoveries of ultra-high pressure (UHP) metamorphism in the Seve Nappe Complex (SNC) of the Scandinavian Caledonides provide the basis for new investigations into the subduction - exhumation dynamics of the Baltoscandian margin during Caledonian tectonism. Specifically, exhumation of (U)HP complexes during subduction remains enigmatic. The recently proposed 'vacuum-cleaner' model details a method of exhumation for the SNC driven by conditions of underpressure within the subduction channel. This model, however, still requires extensive testing. Metasedimentary rocks hosting eclogite boudins of the SNC in Norrbotten, Sweden, preserve both metre-scale folding and a pervasive foliation which were developed during exhumation, as purposed by previous studies. Thus, the SNC host-rock offers an excellent region to test the vacuum-cleaner exhumation model. Preliminary investigation of the host-rock reveals a regional mineral assemblage of Qz + Ms + Grt + Bt + Ksp + Pl + Czo + Aln + Ttn (+ Tur + St). Garnet inclusions (Qz + Rt + Ms) are interpreted to represent the peak pressure assemblage. Chemical profiles of Grt show homogenization of the cores with thin retrogressive rims. Homogenization of Grt requires temperatures >700°C, interpreted to represent peak temperature conditions. Field observations of exhumation-related folds uncovered an axial-planar alignment of mica within the fold hinges, and an abundance of Aln and Czo requires upper-greenschist to lower-amphibolite facies conditions and presence of fluids. The current host-rock mineral assemblage is representative of retrogressive metamorphism at <550-600°C contemporaneous with deformation. Microstructures of the metasedimentary rocks are variable and strongly correlated with competency of the rock. Competent domains abundant in e.g. Qz, Grt, Czo, Ksp etc. exhibit coarse-grained subgrain and bulging-grain recrystallized Qz and development of micrometer-scale shear bands. Less competent domains, dominated by

Sozzy: a hormone-driven autonomous vacuum cleaner

Yamamoto, Masaki

1994-02-01

Domestic robots are promising examples of the application of robotics to personal life. There have been many approaches in this field, but no successful results exist. The problem is that domestic environments are more difficult for robots than other environments, such as factory floors or office floors. Consequently, conventional approaches using a model of human intelligence to design robots have not been successful. In this paper, we report on a prototyped domestic vacuum-cleaning robot that is designed to be able to handle complex environments. The control software is composed of two layers, both of which are generally inspired by behaviors of living creatures. The first layer corresponds to a dynamically reconfigurable system of behaviors implemented in the subsumption architecture. The ability of the robot to support alternate configurations of its behaviors provides the robot with increased robustness. We have conveniently labeled particular configurations as specific `emotions' according to the interpretation of observers of the robot's behavior. The second layer simulates the hormone system. The hormone system is modeled using state variables, increased or decreased by stimuli from the environment. The hormone condition selects the robot's most suitable emotion, according to the changing environments. The robot hardware is built of off-the-shelf parts, such as an embedded CPU, inexpensive home-appliance sensors, and small motors. These parts keep the total building cost to a minimum. The robot also has a vacuum cleaning function to demonstrate its capability to perform useful tasks. We tested the robot in our laboratory, and successfully videotaped its robust behaviors. We also confirmed the hormone system to enhance the robot's plasticity and lifelike quality.

Occupational dermatitis is very common and has a large economic impact. Cleaners are at an increased risk for both work-related cutaneous and respiratory symptoms. To compare the prevalence of occupational cutaneous symptoms among professional indoor cleaners to other building workers (OBW) and to determine associations with exposures and with respiratory symptoms among cleaners. A questionnaire completed by indoor professional cleaners and OBW to compare rash and respiratory symptoms between these groups examined workplace factors such as training, protective equipment and work tasks. In total, 549 of the 1396 professional cleaners (39%) and 593 of the 1271 OBW (47%) completed questionnaires. The prevalence of rash was significantly higher in the cleaners compared to the OBW. For male cleaners, 21% (86/413) had a rash in the past 12 months compared to only 11% (13/115) of OBW (P < 0.05). The rashes experienced by the cleaners were more likely to be on their hands and worse at work. Cleaners washed their hands significantly more often than OBW. Cleaners with a rash were less likely to have received workplace training regarding their skin and were more likely to find the safety training hard to understand. Cleaners with a rash within the past year were significantly more likely to have work-related asthma symptoms than cleaners without a rash (P < 0.001). This study demonstrates a strong link between work-related symptoms of asthma and dermatitis among cleaners. Effective preventive measures, such as the use of protective skin and respiratory equipment, should be emphasized.

Use of cleaners in the manufacturing area demands bottles that will hold a sufficient amount of material and allow for easy and controlled dispensing by the operator without contamination or material leaching from the bottle. The manufacturing storage conditions are also a factor that may affect cleaner chemical integrity and its potential to leave a residue on the part. A variety of squeeze bottles stored in mild (72 F, 10% R.H., dark) and harsh (105 F, 50% R.H., fluorescent lighting) conditions were evaluated to determine the effect of environment and bottle exposure on ozone depleting chemicals (ODC) cleaners chemical composition. Low Density Polyethylene (LDPE) bottles were found to be quite permeable to all the cleaners evaluated in this study indicating this bottle type should not be used in the manufacturing area. Fluorinated Polyethylene (FLPE) bottles showed little cleaner loss and change in cleaner chemical composition over time suggesting these bottles would be acceptable for use. Chemical analysis indicates limonene containing cleaners show increased non-volatile residue (NVR) content with storage under harsh conditions. Some cleaners use BHT (butylated hydroxytoluene) as stabilizer and to protect against limonene oxidation. Under harsh conditions, BHT was quickly depleted resulting in higher NVR levels.

This paper presents a Quality Function Deployment (QFD) analysis of the final down-selected aqueous cleaners to be used on the Redesigned Solid Rocket Motor (RSRM) program. The new cleaner will replace solvent vapor degreasing. The RSRM Ozone Depleting Compound Elimination program is discontinuing the methyl chloroform vapor degreasing process and replacing it with a spray-in-air aqueous cleaning process. Previously, 15 cleaners were down-selected to two candidates by passing screening tests involving toxicity, flammability, cleaning efficiency, contaminant solubility, corrosion potential, cost, and bond strength. The two down-selected cleaners were further evaluated with more intensive testing and evaluated using QFD techniques to assess suitability for cleaning RSRM case and nozzle surfaces in preparation for adhesive bonding.

Comparison of pesticides and other compounds in carpet dust samples collected from used vacuum cleaner bags and from a high-volume surface sampler.

Epidemiologic studies of the association between residential pesticide use and cancer risk require an assessment of past pesticide exposures. Pesticide levels in carpet dust are believed to reflect long-term pesticide use. Recent epidemiologic studies have found collection of dust samples using the high-volume surface sampler (HVS3) to be expensive and cumbersome. We compared the levels of pesticides and other compounds in dust obtained from subjects' personal used vacuum cleaner bags to that collected by the HVS3 to see if this simpler method could replace the HVS3 in epidemiologic research. We visited the homes of 15 subjects, took the used bags from their vacuums, and collected carpet dust samples with the HVS3. The samples were analyzed for 42 target compounds: 26 pesticides, 10 polycyclic aromatic hydrocarbons (PAHs), and six polychlorinated biphenyl (PCB) congeners using GC/MS in selected ion monitoring mode. The two methods agreed in detecting the presence of the target compounds between 80% and 100% of the time. Neither sampling method was consistently more sensitive. The median target compound concentrations were similar, and a paired t-test showed no significant differences. For many compounds, the concentrations of compounds in the HVS3 samples were higher than those in the used bag samples at the upper end of the concentration ranges. However, the Spearman rank correlation coefficients were 0.85 or higher for most compounds, indicating that homes would be ranked similarly using both methods. Overall, there appears to be no clear difference in the quality of the pesticide, PAH, or PCB concentration data for the two dust collection methods. Images Figure 1 PMID:9799187

Parasite infestation increases on coral reefs without cleaner fish

Mutualisms are pivotal in shaping ecological communities. Iconic images of cleaner fish entering the mouths of predatory fish clients to remove ectoparasites epitomize their mutual benefit. Experimental manipulations of cleaner wrasse reveal declines in fish size and growth, and population abundance and diversity of client fishes in the absence of cleaner wrasse. Fishes grow more slowly and are less abundant and diverse on reefs without cleaner wrasse, both for larger species that are regularly cleaned and have high ectoparasite loads ("attractive species"), and for those smaller species that are rarely cleaned and are rarely infested with parasites ("unattractive species"). We therefore considered whether these previously observed declines in individual and population parameters on reefs without cleaners were related to increased ectoparasite infestation using an attractive species ( Hemigymnus melapterus, Labridae) and an unattractive species ( Pomacentrus amboinensis, Pomacentridae). Traps with these fish as a form of bait were deployed to sample blood-sucking gnathiid ectoparasites (Gnathiidae: Isopoda) on reefs from which cleaners ( Labroides dimidiatus, Labridae) have been removed for 13 yr. Cleaner fish could not enter traps to access the clients/hosts, but gnathiids could enter the traps to infest hosts; thus, this method sampled the indirect effect of cleaners on gnathiid infestation of fish. Infestation was higher on reefs without cleaners than on those with them. The effect was only detected during the daytime when cleaners are active and only on the attractive species ( H. melapterus). Thus, cleaner presence indirectly reduced fish exposure to parasites in a species that is highly susceptible to parasites, but not in one that is rarely infested with parasites. This suggests that cleaner presence indirectly reduces exposure of a common fish species to harmful parasites, which may explain some observed benefits in fishes at this location.

Beyond symbiosis: cleaner shrimp clean up in culture.

Cleaner organisms exhibit a remarkable natural behaviour where they consume ectoparasites attached to "client" organisms. While this behaviour can be utilized as a natural method of parasitic disease control (or biocontrol), it is not known whether cleaner organisms can also limit reinfection from parasite eggs and larvae within the environment. Here we show that cleaner shrimp, Lysmata amboinensis, consume eggs and larvae of a harmful monogenean parasite, Neobenedenia sp., in aquaculture. Shrimp consumed parasite eggs under diurnal (63%) and nocturnal (14%) conditions as well as infectious larvae (oncomiracidia) diurnally (26%). Furthermore, we trialled the inclusion of cleaner shrimp for preventative parasite management of ornamental fish, Pseudanthias squamipinnis, and found shrimp reduced oncomiracidia infection success of host fish by half compared to controls (held without shrimp). Fish held without cleaner shrimp exhibited pigmentation changes as a result of infection, possibly indicative of a stress response. These results provide the first empirical evidence that cleaner organisms reduce parasite loads in the environment through non-symbiotic cleaning activities. Our research findings have relevance to aquaculture and the marine ornamental trade, where cleaner shrimp could be applied for prophylaxis and control of ectoparasite infections.

Compulsive buying.

PubMed

Lejoyeux, Michel; Weinstein, Aviv

2010-09-01

Compulsive buying is a chronic, repetitive purchasing that becomes a primary response to negative events and feelings, and may include symptoms equivalent to craving and withdrawal. This article describes the addictive characteristics of compulsive buying, the psychiatric comorbidity, and the possibilities of treatment. Using PubMed and MedLine search engines, we performed a review of published literature over the period 1990-2010 using the keyword "compulsive buying". A key feature distinguishing compulsive buyers from normal consumers, collectors, and hoarders is that the former focuses on the buying process itself, rather than the items bought. In this instance, the purchased items are usually never used, but tend to be hidden or thrown away. A recent screening study found that up to 5% of adult Americans appear to be afflicted with this compulsion. Compulsive buying results in adverse consequences, including financial and legal problems, psychological distress (depression, guilt), and interpersonal conflict. The most commonly associated comorbidities are depression and eating disorders. Nothing is known about the neurobiology and genetics of compulsive buying and relatively little about its treatment. Cognitive behavioral therapy has some efficacy, but no medication has been effective in controlled trials. Compulsive buying can be described as a behavioral dependence. A great deal of future research is needed to improve our understanding of compulsive buying.

2007-06-01

The aim of this cross-sectional study was to assess the prevalence and characteristics of bronchial hyperresponsiveness (BHR) in 43 women cleaners (aged 26 to 57) and 37 women cooks (aged 29 to 55) and compare them with 45 controls (women office workers aged 27 to 58). The evaluation of all subjects included a questionnaire, skin prick tests to common aeroallergens, spirometry, and histamine challenge (PC20 < or = 8 mg mL(-1)). We found higher BHR prevalence in cleaners and cooks than in office workers (30.2 % and 29.7 %, vs. 17.7 %, respectively), but statistical significance was not reached. The prevalence of mild and moderate to severe BHR was similar in all groups. Borderline BHR prevalence was significantly higher in cleaners than in controls (16.2 % vs. 6.6 %, P=0.032) whereas the difference was on the verge of significance in cooks (13.5 % vs. 6.6 %, P=0.081). Moderate to severe BHR was strongly associated with positive family history of asthma and atopy in all groups. Mild BHR was significantly associated with daily smoking in cleaners (P=0.031) and cooks (P=0.021), as well as with the duration of exposure in cleaners (P=0.038). Borderline BHR was closely related to daily smoking and duration of exposure in both cleaners and cooks. Our findings indicate an important role of workplace exposure in borderline BHR development, as well as the significant effect of smoking on mild BHR development in women cleaners and cooks.

Genesis Ultrapure Water Megasonic Wafer Spin Cleaner

NASA Technical Reports Server (NTRS)

Allton, Judith H.; Stansbery, Eileen K.; Calaway, Michael J.; Rodriquez, Melissa C.

2013-01-01

A device removes, with high precision, the majority of surface particle contamination greater than 1-micron-diameter in size from ultrapure semiconductor wafer materials containing implanted solar wind samples returned by NASA's Genesis mission. This cleaning device uses a 1.5-liter/minute flowing stream of heated ultrapure water (UPW) with 1- MHz oscillating megasonic pulse energy focused at 3 to 5 mm away from the wafer surface spinning at 1,000 to 10,000 RPM, depending on sample size. The surface particle contamination is removed by three processes: flowing UPW, megasonic cavitations, and centripetal force from the spinning wafer. The device can also dry the wafer fragment after UPW/megasonic cleaning by continuing to spin the wafer in the cleaning chamber, which is purged with flowing ultrapure nitrogen gas at 65 psi (.448 kPa). The cleaner also uses three types of vacuum chucks that can accommodate all Genesis-flown array fragments in any dimensional shape between 3 and 100 mm in diameter. A sample vacuum chuck, and the manufactured UPW/megasonic nozzle holder, replace the human deficiencies by maintaining a consistent distance between the nozzle and wafer surface as well as allowing for longer cleaning time. The 3- to 5-mm critical distance is important for the ability to remove particles by megasonic cavitations. The increased UPW sonication time and exposure to heated UPW improve the removal of 1- to 5-micron-sized particles.

Keen, Jill M.; Sagers, Neil W.; McCool, Alex (Technical Monitor)

2001-01-01

Government regulations have mandated production phase-outs of a number of solvents, including 1,1,1-trichloroethane, an ozone-depleting chemical (ODC). This solvent was used extensively in the production of the Reusable Solid Rocket Motors (RSRMs) for the Space Shuttle. Many tests have been performed to identify replacement cleaners. One major area of concern in the selection of a new cleaner has been compatibility. Some specific areas considered included cleaner compatibility with non-metallic surfaces, painted surfaces, support materials such as gloves and wipers as well as corrosive properties of the cleaners on the alloys used on these motors. The intent of this paper is to summarize the test logic, methodology, and results acquired from testing the many cleaner and material combinations.

The effectiveness of stand alone air cleaners for shelter-in-place.

PubMed

Ward, M; Siegel, J A; Corsi, R L

2005-04-01

Stand-alone air cleaners may be efficient for rapid removal of indoor fine particles and have potential use for shelter-in-place (SIP) strategies following acts of bioterrorism. A screening model was employed to ascertain the potential significance of size-resolved particle (0.1-2 microm) removal using portable high efficiency particle arresting (HEPA) air cleaners in residential buildings following an outdoor release of particles. The number of stand-alone air cleaners, air exchange rate, volumetric flow rate through the heating, ventilating and air-conditioning (HVAC) system, and size-resolved particle removal efficiency in the HVAC filter were varied. The effectiveness of air cleaners for SIP was evaluated in terms of the outdoor and the indoor particle concentration with air cleaner(s) relative to the indoor concentration without air cleaners. Through transient and steady-state analysis of the model it was determined that one to three portable HEPA air cleaners can be effective for SIP following outdoor bioaerosol releases, with maximum reductions in particle concentrations as high as 90% relative to conditions in which an air cleaner is not employed. The relative effectiveness of HEPA air cleaners vs. other removal mechanisms was predicted to decrease with increasing particle size, because of increasing competition by particle deposition with indoor surfaces and removal to HVAC filters. However, the effect of particle size was relatively small for most scenarios considered here. The results of a screening analysis suggest that stand-alone (portable) air cleaners that contain high efficiency particle arresting (HEPA) filters can be effective for reducing indoor fine particle concentrations in residential dwellings during outdoor releases of biological warfare agents. The relative effectiveness of stand-alone air cleaners for reducing occupants' exposure to particles of outdoor origin depends on several factors, including the type of heating, ventilating and air

[Effectiveness and limits of the cleaners steam in hospitals].

PubMed

Meunier, O; Meistermann, C; Schwebel, A

2009-05-01

We assessed bactericidal activity of the cleaners steam used for the bio-cleaning of the hospital surfaces. We performed of samples (Rodac) before and after use of cleaner steam and compared with bactericidal effect of disinfecting detergent used in hospital for surfaces. We studied this effectiveness for different time of steam contact. Finally, we wanted to prove, by air sampling, that aero-bio-contamination was possible generated by using cleaners steam. We show that bactericidal effect of the cleaner steam is superior of some tested disinfecting detergent, for the treatment of one square meter till 2 min. This effectiveness diminishes to be just identical in that some disinfecting detergent when use of the cleaner steam is up to two or four square meters surfaces till 2 min. On the other hand, the cleaner steam is less efficient in terms of bacterial destruction when the time of contact steam-soil is superior in 2 min for six square meter surface. The air bacterial pollution, generated by the use of the cleaner steam, is restricted and not significantly augmented if measured in 44 cm above the soil in the course of cleaning. The cleaner steam is indeed a very good equipment for the cleaning of surfaces but it is necessary to respect a time of minimal contact of 2 min for four square meters surfaces treaties to acquire an antibacterial effect at least so important as that acquired with used disinfecting detergent. The disinfection of surfaces is then user-dependent and the time of requested contact is can be not compatible with hospital obligations.

Biting cleaner fish use altruism to deceive image-scoring client reef fish.

PubMed Central

Bshary, Redouan

2002-01-01

Humans are more likely to help those who they have observed helping others previously. Individuals may thus benefit from being altruistic without direct reciprocity of recipients but due to gains in 'image' and associated indirect reciprocity. I suggest, however, that image-scoring individuals may be exploitable by cheaters if pay-offs vary between interactions. I illustrate this point with data on cleaner-client reef fish interactions. I show the following: (i) there is strong variation between cleaners with respect to cheating of clients (i.e. feeding on client tissue instead of parasites); (ii) clients approach cleaners, that they observe cooperating with their current client and avoid cleaners that they observe cheating; (iii) cleaners that cheat frequently are avoided more frequently than more cooperative cleaners (iv) cleaners that cheat frequently behave altruistically towards their smallest client species; (v) altruistic acts are followed by exploitative interactions. Thus, it appears that cleaners indeed have an image score, which selects for cooperative cleaners. However, cheating cleaners use altruism in potentially low-pay-off interactions to deceive and attract image-scoring clients that will be exploited. PMID:12396482

Critically safe vacuum pickup for use in wet or dry cleanup of radioactive materials

DOEpatents

Zeren, Joseph D.

1994-01-01

A vacuum pickup of critically safe quantity and geometric shape is used in cleanup of radioactive materials. Collected radioactive material is accumulated in four vertical, parallel, equally spaced canisters arranged in a cylinder configuration. Each canister contains a filter bag. An upper intake manifold includes four 90 degree spaced, downward facing nipples. Each nipple communicates with the top of a canister. The bottom of each canister communicates with an exhaust manifold comprising four radially extending tubes that meet at the bottom of a centrally located vertical cylinder. The top of the central cylinder terminates at a motor/fan power head. A removable HEPA filter is located intermediate the top of the central cylinder and the power head. Four horizontal bypass tubes connect the top of the central cylinder to the top of each of the canisters. Air enters the vacuum cleaner via a hose connected to the intake manifold. Air then travels down the canisters, where particulate material is accumulated in generally equal quantities in each filter bag. Four air paths of bag filtered air then pass radially inward to the bottom of the central cylinder. Air moves up the central cylinder, through the HEPA filter, through a vacuum fan compartment, and exits the vacuum cleaner. A float air flow valve is mounted at the top of the central cylinder. When liquid accumulates to a given level within the central cylinder, the four bypass tubes, and the four canisters, suction is terminated by operation of the float valve.

Although compulsive buying (CB) seems to be not only prevalent but even increasing in prevalence, it often remains neglected or minimized in clinical settings. There is a need for a greater understanding and recognition of this problem. The aim of this article is to summarize the current knowledge regarding CB and to offer thoughts regarding classification. Review of published literature over the period 1994-2013 through Pubmed/Medline, PsychINFO, and Google Scholar using the key words 'compulsive buying', 'impulsive buying' and 'addictive buying'. CB is defined by a preoccupation with buying and shopping, by frequent buying episodes, or overpowering urges to buy that are experienced as irresistible and senseless. The maladaptive spending behavior is associated with serious psychological, social, occupational, and financial problems. Treatment-seeking patients with CB suffer from substantial psychiatric comorbidity (eg, anxiety and depressive mood disorders, compulsive hoarding, binge eating disorder). Representative surveys revealed prevalence estimates of CB between 6% and 7% and indicate that younger people are more prone to develop CB. Moreover, European data suggest an increase of CB in the adult population over the last 20 years. While there is no evidence for the efficacy of psychopharmacological treatment, group cognitive behavioral therapy has been shown to be effective. The relevance of recognition of CB as mental disorder is undeniable in the face of its estimated prevalence and associated burden. As our understanding of contributing neurobiological and etiological factors is limited, further research should focus on these topics, taking into account the heterogeneity of individuals with CB. There is also a need for specific treatment options and for the development of prevention strategies. © American Academy of Addiction Psychiatry.

Hospital trash: cleaners speak of their role in disease prevention.

PubMed

Messing, K

1998-06-01

Feminist researchers have contrasted the caring provided by women in hospitals with a more fragmented "curing" approach, which they identify with the predominantly male professions of medicine and surgery. The author spoke with hospital cleaners about their jobs and their health. Several themes emerged: the invisibility of the cleaning function, lack of respect for cleaners, representations of cleaning as undemanding, and assumptions that women's work in cleaning is particularly easy. Cleaners use various strategies to combat these stereotypes but receive little help from administrators or fellow employees. There is a hierarchy in the status of Québec hospital workers with curing (doctors) at the top, followed by caring and healing (nurses, therapists, and attendants), and hygiene (cleaners, sterilizers, and launderers) at the bottom. Authority hierarchies in health care are not related to gender in a simple way, although there is discrimination against women cleaners. The fact that cleaning, especially cleaning performed by women, is invisible to managers, other hospital personnel, and patients has important consequences for cleaners' and for patients' health.

Evaluation of the efficiency of denture cleaners for removing denture adhesives.

2016-12-01

We developed a new scoring index for assessing the removability of denture adhesives and evaluated the removal efficiency of denture cleaners. Although our understanding of the importance of denture care is increasing, little is known about the effectiveness and efficiency of denture cleaners on denture adhesives. Therefore, guidelines for proper cleaning are necessary. We used five denture cleaner solutions on two cream adhesives, one powder adhesive and one cushion adhesive. After immersion in the denture cleaners for a designated time, we evaluated the area of the sample plate still covered by denture adhesive. Cream adhesives were removed more completely after immersion in majority of the denture cleaners than in water. Powder adhesive was removed more quickly than cream adhesives. Cushion adhesive was not removed by immersion in either the denture cleaners or water control. Some denture cleaners could liquefy cream adhesives more than water, but these differences were not observed in case of powder and cushion adhesives. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

2008-09-01

The cleaning profession has been associated with multiple ergonomic and chemical hazards which elevate the risk for occupational injury. This study investigated the epidemiology of occupational injury among cleaners in healthcare work settings in the Canadian province of British Columbia. Incidents of occupational injury among cleaners, resulting in lost time from work or medical care, over a period of 1 year in two healthcare regions were extracted from a standardized operational database and with person-years obtained from payroll data. Detailed analysis was conducted using Poisson regression modeling. A total of 145 injuries were identified among cleaners, with an annual incidence rate of 32.1 per 100 person-years. After adjustment for age, gender, subsector, facility, experience and employment status, Poisson regression models demonstrated that a significantly higher relative risk (RR) of all injury, musculoskeletal injury and cuts was associated with cleaning work in acute care facilities, compared with long-term care facilities. Female cleaners were at a higher RR of all injuries and contusions than male cleaners. A lower risk of all injury and allergy and irritation incidents among part-time or casual workers was found. Cleaners with >10 years of experience were at significantly lower risk for all injury, contusion and allergy and irritation incidents. Cleaners were found to be at an elevated risk of all injury categories compared with healthcare workers in general.

COMPULSIVE BUYING TENDENCIES.

PubMed

Spinella, Marcello; Lester, David; Yang, Bijou

2015-12-01

Compulsive buying behavior is typically viewed as pathological, but recent research has shown that compulsive buying tendencies are associated with attitudes toward money, personal financial behavior, and having materialistic values, suggesting that compulsive buyers are manifesting an extreme form of habits shown by people in general. In a study of 240 community residents, scores on the Compulsive Buying Scale were associated positively with scores on the Material Values Scale and the Canadian Problem Gambling Index, and negatively with scores on the Executive Personal Finance Scale and Ardelt's wisdom scale. These results suggest that, as is the case for many abnormal behaviors, tendencies toward compulsive buying may not be pathological, but are associated with attitudes toward money in general, financial management behavior, and materialistic values.

Cleaner wrasse prefer client mucus: support for partner control mechanisms in cleaning interactions.

PubMed

Grutter, Alexandra S; Bshary, Redouan

2003-11-07

Recent studies on cleaning behaviour suggest that there are conflicts between cleaners and their clients over what cleaners eat. The diet of cleaners usually contains ectoparasites and some client tissue. It is unclear, however, whether cleaners prefer client tissue over ectoparasites or whether they include client tissue in their diet only when searching for parasites alone is not profitable. To distinguish between these two hypotheses, we trained cleaner fish Labroides dimidiatus to feed from plates and offered them client mucus from the parrotfish Chlorurus sordidus, parasitic monogenean flatworms, parasitic gnathiid isopods and boiled flour glue as a control. We found that cleaners ate more mucus and monogeneans than gnathiids, with gnathiids eaten slightly more often than the control substance. Because gnathiids are the most abundant ectoparasites, our results suggest a potential for conflict between cleaners and clients over what the cleaner should eat, and support studies emphasizing the importance of partner control in keeping cleaning interactions mutualistic.

Because of the 1990 Clean Air Act Amendment many chlorinated solvents are being phased out of use in manufacturing industries. Replacement of the ODC (ozone- depleting chemicals) with less volatile, non-ozone depleting cleaners has been extensively studied over the past nine years at Thiokol Propulsion, Cordant Technologies. Many of the non-ODC cleaners contain compounds that can potentially degrade over time under conditions of high temperature, humidity and exposure to light. The chemical composition of environmentally conditioned cleaners and the subsequent effect on aluminum/amine-cured epoxy bond integrity as measured by Tapered Double Cantilever Beam were evaluated. From this study it is observed that moisture content increases for those cleaners containing polar compounds. Non-volatile residue content increases as stabilizers are depleted and the chemical compound limonene is oxidized. A change in aluminum/ amine-cured epoxy bond fracture toughness is observed as some of these cleaners age with increases in moisture and NVR content.

Compulsive buying is an excessive behavior that has begun to receive attention from researchers in recent years. The current study provides an overview of research on compulsive buying and examines the psychiatric co-morbidity in a German female treatment seeking compulsive buying sample in comparison with age and gender-matched normal buying control groups. Thirty women suffering from compulsive buying disorder, 30 community controls, and 30 bariatric surgery candidates were assessed with the German versions of the Structured Clinical Interview for DSM-IV diagnoses (SCID). Women with compulsive buying disorder showed significantly higher prevalence rates of affective, anxiety, and eating disorders compared to community controls, and suffered significantly more often from affective and anxiety disorders compared to bariatric surgery candidates. The compulsive buying group presented with the highest rates of personality disorders, most commonly avoidant, depressive, obsessive-compulsive, and borderline personality disorder, and reported the highest prevalence rates of other impulse control disorders, especially for intermittent explosive disorder. The findings suggest an elevated psychiatric co-morbidity in patients with compulsive buying disorder.

A brief study has been undertaken to evaluate the performance of noncontact cleaning agents for use on solar collectors. Several techniques are used to compare cleansing agents which have been recommended by their respective manufacturers for cleaning solar mirrors. Wetting and residue buildup properties are evaluated for over 50 of these commercially available cleaners. The wetting properties of each cleaner are evaluated by measuring the growth of the contact area of a constant volume drop as a function of time. Losses due to residue buildup are solar weighted and considered equally with the wetting parameters and cost figures to constructmore » a figure of merit for cleaner comparison.« less

The insight that animals' cognitive abilities are linked to their evolutionary history, and hence their ecology, provides the framework for the comparative approach. Despite primates renowned dietary complexity and social cognition, including cooperative abilities, we here demonstrate that cleaner wrasse outperform three primate species, capuchin monkeys, chimpanzees and orang-utans, in a foraging task involving a choice between two actions, both of which yield identical immediate rewards, but only one of which yields an additional delayed reward. The foraging task decisions involve partner choice in cleaners: they must service visiting client reef fish before resident clients to access both; otherwise the former switch to a different cleaner. Wild caught adult, but not juvenile, cleaners learned to solve the task quickly and relearned the task when it was reversed. The majority of primates failed to perform above chance after 100 trials, which is in sharp contrast to previous studies showing that primates easily learn to choose an action that yields immediate double rewards compared to an alternative action. In conclusion, the adult cleaners' ability to choose a superior action with initially neutral consequences is likely due to repeated exposure in nature, which leads to specific learned optimal foraging decision rules.

Recent studies have shown an excess risk of asthma for cleaners, but it is not clear which cleaning-related exposures induce or aggravate asthma. Risk factors for asthma were studied among indoor cleaners participating in the Spanish part of the European Community Respiratory Health Survey in 1992. In 1998, 78 of the 91 subjects reporting cleaning-related jobs in 1992 were identified. Of these, 67 indoor cleaners were interviewed by telephone about their cleaning activities and their use of cleaning products in 1992. These data were related to asthma prevalence in 1992, and the cleaners were compared with a reference group of office workers. Asthma prevalence was 1.7 times higher [95% confidence interval (95% CI) 1.1-2.6] among the cleaners than among the referents, being highest among private home cleaners (3.3, 95% CI 1.9-5.8). The prevalence of housedust mite sensitization amounted to 28% for the home cleaners and was significantly (P<0.01) higher than for other indoor cleaners (3%), but similar to the corresponding prevalence of office workers (22%). More than half of the cleaners reported work-related respiratory symptoms. The asthma risk of the home cleaners was mainly associated with kitchen cleaning and furniture polishing, with the use of oven sprays and polishes. The asthma risk of Spanish cleaners is primarily related to the cleaning of private homes. This relationship may be explained by the use of sprays and other products in kitchen cleaning and furniture polishing.

Adjusting one's behaviour in response to eavesdropping bystanders is considered a sophisticated social strategy, yet the underlying mechanisms are not well studied. Cleaner wrasse, Labroides dimidiatus, cooperate by eating ectoparasites off "client" fishes, or cheat (i.e. bite) and eat client mucus. Image scoring by bystander clients generally causes cleaners from socially-complex (i.e. high cleaner and client abundance; high client species richness) habitats to increase levels of cooperation. However, some individuals may periodically provide tactile stimulation to small resident clients, which attract bystanders close that are bitten, a form of tactical deception. Cortisol injection can reproduce this pattern. Here, we tested whether cleaners from socially-complex versus simple habitats respond differently to cortisol injections in terms of their cleaning interactions with clients. We found that only cleaners from the socially-complex habitat respond to cortisol injection with strategies functioning as tactical deception: i.e. increased tactile stimulation to small clients and increased cheating of large clients relative to small ones. At the socially-simple site, where reputation management is less important, cortisol-treated fish increased their overall levels of cheating, especially of small clients. Thus, strategic adjustments to cooperative behaviour and tactical deception are likely context-dependent, forming part of general reputation management abilities in cleaner wrasse.

Compulsive buying is an under-recognised entity among Indian psychiatrists. A Medline search, hand searching of journals and direct communications with lead investigators in compulsive buying have generated numerous studies. Overseas data indicate a community prevalence between 1% and 8% . The phenomenon can be an independent entity or appears as a comorbidity with another axis I or axis II disorder. A degree of suspicion on part of clinician regarding its possible presence is the key to its detection. A few rating instruments are available to quantify the morbidity and screening for compulsive buying. Management involves pharmacotherapy with SSRIs, psychotherapy, self-help groups and self-help books. Epidemiological and clinical studies on compulsive buying should be undertaken by Indian psychiatrists to provide better services for people suffering from compulsive buying.

The aims of this study were twofold. On the one hand, to reach an understanding of, and to illustrate the experience of addictive buying and, on the other, to throw some light on the controversial subject of addicts' personal responsibility for their behavior. With these aims, a thematic analysis of an extensive diary written by a compulsive buyer is presented. Four themes emerge from the analysis: the defining characteristics of addiction to buying that determine the boundary separating it from other forms of impulsive or careless buying; several causal factors; the role that money and material objects play in family relationships and friendships through the symbolic meanings they adopt; and the relationship of personal values with impulsiveness and self-control. In view of the results, the moral model of addiction to buying is discussed, and an explanatory model of the ambivalence that is characteristic of addiction to buying is proposed, based on a personal hierarchy of values.

Sea lice infestations represent one of the most significant challenges facing the salmon farming industry, giving rise to lost production, additional costs of treatment and potential negative interactions with wild stocks. At present, cleaner fish, which actively remove lice from salmon, are an effective, biological, long-term option which has been adopted by many countries. In Ireland, several key studies were conducted in the 1990s on the use of wild-caught wrasse (corkwing, goldsinny and rock cook) as cleaner fish in experimental and commercial scale trials. More recently, the National University of Ireland Galway (NUIG), at their marine research facility in Carna (CRS), has undertaken applied research on ballan wrasse and lumpsucker. Currently, CRS is providing lumpsucker juveniles and research and development for the Irish salmon industry with support from BIM (Ireland's Seafood Development Agency) and Marine Harvest Ireland. There is a large amount of research currently being carried out in this area in all countries that are utilizing cleaner fish technology. The current focus in Ireland is the development of a native lumpsucker broodstock to facilitate its sustainable production. The aim of this article was to provide an overview of the research, challenges and use of cleaner fish in Ireland. © 2017 The Authors Journal of Fish Diseases Published by John Wiley & Sons Ltd.

In spite of a hundred year long history of scientific research compulsive buying has been a hardly known phenomenon until today. Ambiguous scientific information makes it impossible to classify compulsive buying as a separate mental disorder. Recently many researchers have noticed phenomenological compatibility of compulsive buying with behavioural addictions. Nowadays, there is reasonable grounds that compulsive buying disorder can be defined as an addiction. There are many similarities occurring between a consumer type behaviours in compulsive buyers and a pathologic consumption of psychoactive substances which included the obsessive need to consumer or a compulsion to consume, personal dependence and loss of control over self-behaviour, as well as tendencies to the consumption increase. Compulsive buying disorder differs in its course from the compulsive behaviours. A strong compulsion to make a given activity, often impossible to restrain is associated with overwhelming but acceptable desire to purchase a specific item. Due to the latest information about the described phenomenon, it has been decided to present current knowledge of adequate classifications, epidemiology and therapy of compulsive buyers. In the article authors' own standpoint as regards pathogenesis and potential risk factors was described.

Reducing occupant exposure to indoor mold is the goal of this research, through the efficacy testing of antimicrobial cleaners. Often mold contaminated building materials are not properly removed, but instead surface cleaners are applied in an attempt to alleviate the problem. The efficacy of antimicrobial cleaners to remove, eliminate or control mold growth on surfaces can easily be tested on non-porous surfaces. However, the testing of antimicrobial cleaner efficacy on porous surfaces, such as those found in the indoor environment such as gypsum board can be more complicated and prone to incorrect conclusions regarding residual organisms. The mold Stachybotrys chartarum has been found to be associated with idiopathic pulmonary hemorrhage in infants and has been studied for toxin production and its occurrence in water damaged buildings. Growth of S. chartarum on building materials such as gypsum wallboard has been frequently documented. Research to control S. chartarum growth using 13 separate antimicrobial cleaners on contaminated gypsum wallboard has been performed in laboratory testing. Popular brands of cleaning products were tested by following directions printed on the product packaging. A variety of gypsum wallboard surfaces were used to test these cleaning products at high relative humidity. The results indicate differences in antimicrobial efficacy for the six month period of testing. Results for the six types of GWB surfaces varied extensively. However, three cleaning products exhibited significantly better results than others. Lysol All-Purpose Cleaner-Orange Breeze (full strength) demonstrated results which ranked among the best in five of the six surfaces tested. Both Borax and Orange Glo Multipurpose Degreaser demonstrated results which ranked among the best in four of the six surfaces tested. The best antimicrobial cleaner to choose is often dependent on the type of surface to be cleaned of S. chartarum contamination. For Plain GWB, no paint, the

Childhood trauma and compulsive buying.

2013-02-01

Childhood trauma has been empirically associated with various types of self-regulatory difficulties in adulthood. However, according to the extant literature, no study has examined relationships between various types of childhood trauma and compulsive buying behavior in adulthood. Using a self-report survey methodology in a cross-sectional consecutive sample of 370 obstetrics/gynecology patients, we examined five types of childhood trauma before the age of 12 years (i.e. witnessing violence, physical neglect, emotional abuse, physical abuse, sexual abuse) in relationship to compulsive buying as assessed by the Compulsive Buying Scale (CBS). All forms of trauma demonstrated statistically significant correlations with the CBS. Using a linear regression analysis, both witnessing violence and emotional abuse significantly contributed to CBS scores. Further analyses indicated that race did not moderate the relationship between childhood trauma and compulsive buying. Findings indicate that various forms of childhood trauma are correlated with compulsive buying behavior, particularly witnessing violence and emotional abuse.

Hoarding in a compulsive buying sample.

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.

Psychosocial work factors and shoulder pain in hotel room cleaners.

2010-07-01

Hotel room cleaners have physically demanding jobs that place them at high risk for shoulder pain. Psychosocial work factors may also play a role in shoulder pain, but their independent role has not been studied in this group. Seventy-four percent (941 of 1,276) of hotel room cleaners from five Las Vegas hotels completed a 29-page survey assessing health status, working conditions, and psychosocial work factors. For this study, 493 of the 941 (52%) with complete data for 21 variables were included in multivariate logistic regression analyses. Fifty-six percent reported shoulder pain in the prior four weeks. Room cleaners with effort-reward imbalance (ERI) were three times as likely to report shoulder pain (OR 2.99, 95% CI 1.95-4.59, P = 0.000) even after adjustment for physical workload and other factors. After adjustment for physical workload, job strain and iso-strain were not significantly associated with shoulder pain. ERI is independently associated with shoulder pain in hotel room cleaners even after adjustment for physical workload and other risk factors. 2010 Wiley-Liss, Inc.

Impulsive buying makes billions of dollars for retail businesses every year, particularly in an era of thriving e-commerce. Narcissism, characterized by impulsivity and materialism, may serve as a potential antecedent to impulsive buying. To test this hypothesis, two studies examined the relationship between narcissism and impulsive buying. In Study 1, we surveyed an online sample and found that while adaptive narcissism was not correlated with impulsive buying, maladaptive narcissism was significantly predictive of the impulsive buying tendency. By investigating 304 twin pairs, Study 2 showed that global narcissism and its two components, adaptive and maladaptive narcissism, as well as the impulsive buying tendency were heritable. The study found, moreover, that the connections between global narcissism and impulsive buying, and between maladaptive narcissism and impulsive buying were genetically based. These findings not only establish a link between narcissism and impulsive buying but also help to identify the origins of the link. The present studies deepen our understanding of narcissism, impulsive buying, and their interrelationship. PMID:26217251

Cleaner fish drives local fish diversity on coral reefs.

PubMed

Grutter, Alexandra S; Murphy, Jan Maree; Choat, J Howard

2003-01-08

Coral reefs are one of the most diverse habitats in the world, yet our understanding of the processes affecting their biodiversity is limited. At the local scale, cleaner fish are thought to have a disproportionate effect, in relation to their abundance and size, on the activity of many other fish species, but confirmation of this species' effect on local fish diversity has proved elusive. The cleaner fish Labroides dimidiatus has major effects on fish activity patterns and may indirectly affect fish demography through the removal of large numbers of parasites. Here we show that small reefs where L. dimidiatus had been experimentally excluded for 18 months had half the species diversity of fish and one-fourth the abundance of individuals. Only fish that move among reefs, however, were affected. These fish include large species that themselves can affect other reef organisms. In contrast, the distribution of resident fish was not affected by cleaner fish. Thus, many fish appear to choose reefs based on the presence of cleaner fish. Our findings indicate that a single small and not very abundant fish has a strong influence on the movement patterns, habitat choice, activity, and local diversity and abundance of a wide variety of reef fish species.

The present work was a longitudinal study on Schistosoma mansoni infection in occupationally hyperexposed canal cleaners in the Sudan and the influence of therapy on the parasitological and humoral immune parameters. Chronically infected canal cleaners (n = 28) were more resistant to reinfection (Fisher's exact test, P < 0.05) than newly recruited canal cleaners (n = 17). Chronically infected canal cleaners had a significantly higher degree of Symmers' fibrosis (χ2 = 19.1, P < 0.0001), significantly larger portal vein diameter (P < 0.05) and enlarged spleen (χ2 = 4.2, P < 0.05) than recently infected, newly recruited canal cleaners. ELISA was used to detect IgG, IgA and IgM in response to whole worm homogenate (WWH) and cercarial homogenate (CH). Chronically infected canal cleaners had significantly higher IgG to WWH antigen than newly recruited canal cleaners and normally exposed individuals (P < 0.05), while both chronically infected and newly recruited canal cleaners had higher IgG levels to CH antigen than normally exposed individuals (P < 0.05). The newly recruited canal cleaners had a significantly higher IgM level to CH antigen than chronically infected canal cleaners (P < 0.05). The IgG level to WWH antigen increased significantly after treatment in newly recruited canal cleaners and normally exposed individuals (P < 0.05). The IgA level to CH antigen increased significantly after treatment in the chronically infected group (P < 0.05). Comparison of the serological parameters between the different study groups with regards to infection and treatment is discussed. PMID:9099926

Kleptomania and compulsive buying are important clinical problems. However there is no established treatment for these problems in Japan yet. In this article, we review the available clinical treatments for kleptomania and compulsive buying in Japan. Kleptomania and compulsive buying can be explained by the conditioning theory. These behaviors are reinforced by positive consequences. In particular, the problem behaviors of kleptomania arise because of arousal and tension and are reinforced by the relaxed feeling that follows. Therefore, kleptomania is treated by systematic desensitization. However, it is important that interventions such as cognitive behavioral therapy, which increase subjective adaptation. be used in combination to treat and control such behaviors.

The CLEANER-Hydrologic Observatory* initiative is a distributed network for research on complex environmental systems that focuses on the intersecting water-related issues of both the CUAHSI and CLEANER communities. It emphasizes research on the nation's water resources related to human-dominated natural and built environments. The network will be comprised of: interacting field sites with an integrated cyberinfrastructure; a centralized technical resource staff and management infrastructure to support interdisciplinary research through data collection from advanced sensor systems, data mining and aggregation from multiple sources and databases; cyber-tools for analysis, visualization, and predictive multi-scale modeling that is dynamically driven. As such, the network will transform 21st century workforce development in the water-related intersection of environmental science and engineering, as well as enable substantial educational and engagement opportunities for all age levels. The scientific goal and strategic intent of the CLEANER-Hydrologic Observatory Network is to transform our understanding of the earth's water cycle and associated biogeochemical cycles across spatial and temporal scales-enabling quantitative forecasts of critical water-related processes, especially those that affect and are affected by human activities. This strategy will develop scientific and engineering tools that will enable more effective adaptive approaches for resource management. The need for the network is based on three critical deficiencies in current abilities to understand large-scale environmental processes and thereby develop more effective management strategies. First we lack basic data and the infrastructure to collect them at the needed resolution. Second, we lack the means to integrate data across scales from different media (paper records, electronic worksheets, web-based) and sources (observations, experiments, simulations). Third, we lack sufficiently accurate

Cognitive behavioral therapy for compulsive buying disorder.

Mitchell, James E; Burgard, Melissa; Faber, Ron; Crosby, Ross D; de Zwaan, Martina

2006-12-01

To our knowledge, no psychotherapy treatment studies for compulsive buying have been published. The authors conducted a pilot trial comparing the efficacy of a group cognitive behavioral intervention designed for the treatment of compulsive buying to a waiting list control. Twenty-eight subjects were assigned to receive active treatment and 11 to the waiting list control group. The results at the end of treatment showed significant advantages for cognitive behavioral therapy (CBT) over the waiting list in reductions in the number of compulsive buying episodes and time spent buying, as well as scores on the Yale-Brown Obsessive Compulsive Scale--Shopping Version and the Compulsive Buying Scale. Improvement was well-maintained at 6-month follow-up. The pilot data suggests that a cognitive behavioral intervention can be quite effective in the treatment of compulsive buying disorder. This model requires further testing.

Compulsive buyers feel a continual urge to buy things, irrespective of their financial means. Interest in compulsive buying has increased in the last 30 to 40 years. Since excessive buying is a regularly occurring feature of various illnesses encountered in clinical practice, one wonders whether it should be regarded as a sign of the times, as a symptom of a psychiatric illness or as a distinct psychiatric syndrome. To gain insight into the concept of compulsive buying. We searched the literature via Medline, PubMed and PsycInfo for the period from 1966 to August 2008. results Compulsive buying is a relatively unknown and poorly defined phenomenon, despite its high incidence and high comorbidity. It is characterised by chronic, repetetive behaviour; it occurs mainly among women and should be classified as an impulsive-control disorder nos. Current aetiological models lack explanatory power and, so far, the most successful treatment results seem to have been achieved with behavioural therapy. Compulsive buying should be considered from a neuroscientific perspective. Future research needs to have a neuropsychiatric focus and a contextual psychological and behavioural analytical approach in which inhibition, self-control and rule-governed behaviour play a central role.

Compulsive buying and borderline personality symptomatology.

PubMed

Sansone, Randy A; Chang, Joy; Jewell, Bryan; Sellbom, Martin; Bidwell, Mark

2013-04-01

In this study, the authors investigated the relationship between compulsive buying and borderline personality disorder (BPD) symptomatology--two disorders possibly linked through impulsivity. Using a survey methodology in a cross-sectional consecutive sample of nonemergent female outpatients from an obstetrics/gynecology clinic, the authors assessed compulsive buying with the compulsive buying scale (CBS) and BPD symptomatology through the BPD scale of the personality diagnostic questionnaire-4 (PDQ-4) and the self-harm Inventory (SHI). In this sample, 8% of Caucasian women and 9% of African-American women scored positively for compulsive buying. The correlations between scores on the CBS and the PDQ-4 and SHI were 0.43 and 0.41, respectively-both statistically significant at the p < .001 level. Compared to Caucasian women, African-American women demonstrated statistical associations between the BPD measures and the CBS scale scores that were significantly larger. Findings suggest relationships between compulsive buying and BPD, particularly among African-American women.

Background and study aims  Water drop adhesions (WDA) impair endoscopic view during gastrointestinal endoscopy. We developed a novel lens cleaner designed using two types of harmLess surfactants and it is reported to be useful for preventing lens cloudiness during colorectal ESD. In the current study, we examined the ability of it for preventing and removing WDA. Patients and methods  During laboratory experiments, the cleaner (Cleash; Fujifilm Co., Tokyo, Japan and Nagase Medicals Co., Hyogo, Japan) was applied to the endoscopic lens and an air/water device (AWD) (water 200 mL, dimethicone 1 mL, Cleash 1 mL). The endoscope was submerged in water 100 times for 5 cycles. Rates of WDA were calculated for various groups (lens and AWD with or without Cleash) and compared to a normal cleaner (SL cleaner). During clinical research, 30 colonoscopies and 30 esophagogastroduodenoscopies were analyzed. For the Cleash group, the cleaner was applied to both lens and AWD. The numbers of WDA and WDA with non-rapid removal were calculated, compared to those of the SL cleaner group. Results  The mean WDA rate for the Cleash setting (lens: Cleash; AWD: Cleash) was 11.0 %, which was significantly lower than other settings (lens: SL cleaner; AWD: water, 31.0 %; P  < 0.001) (lens: Cleash; AWD: water, 19.0 %; P  < 0.001). Clinical research of colonoscopies indicated that the numbers of WDA (number/15 sec) and WDA with non-rapid removal were 0.38 and 0.17 for the Cleash group and 0.91 and 0.46 for the SL cleaner groups ( P  < 0.001, P  < 0.001). For esophagogastroduodenoscopies, the results were 0.47 and 0.24 for the Cleash group and 0.54 and 0.42 for the SL cleaner group ( P  = 0.72, P  = 0.018). Conclusion  A clear and beautiful image without WDA is useful not only for routine endoscopy but also, more importantly, for magnifying endoscopy and other endoscopic treatments. The use of Cleash to lens and AWD showed positive results for

Residential wood combustion is an important source of ambient air pollution, accounting for over 25% of fine particulate matter (PM2.5) emissions in Canada. In addition to these ambient contributions, wood smoke pollutants can enter the indoor environment directly when loading or stoking stoves, resulting in a high potential for human exposure. A study of the effectiveness of air cleaners at reducing wood smoke-associated PM2.5 of indoor and outdoor origin was conducted in 31 homes during winter 2009-10. Day 1, the residents' wood burning appliance operated as usual with no air cleaner. Days 2 and 3, the wood burning appliance was not operational and the air cleaner was randomly chosen to operate in "filtration" or "placebo filtration" mode. When the air cleaner was operating, total indoor PM2.5 levels were significantly lower than on placebo filtration days (p = 0.0001) resulting in a median reduction of 52%. There was also a reduction in the median PM2.5 infiltration factor from 0.56 to 0.26 between these 2 days, suggesting the air cleaner was responsible for increased PM2.5 deposition on filtration days. Our findings suggest that the use of an air cleaner reduces exposure to indoor PM2.5 resulting from both indoor and ambient wood smoke sources.

Different facets of compulsive buying among Chinese students

PubMed Central

LI, SHUANG; UNGER, ALEXANDER; BI, CHONGZENG

2014-01-01

Background and aims: Compulsive buying is a severe phenomenon, especially among younger consumers. It is well documented in Western industrial societies like the USA and Germany, and nowadays an increasing interest in compulsive buying in non-Western countries is on the rise. Methods: In the current study, we measured the prevalence of compulsive buying tendencies among Chinese female and male students by using a Chinese translation of the German Compulsive Buying Scale (Raab, Neuner, Reisch & Scherhorn, 2005). We examined the influence of gender, location and age using ANCOVA, and binary logistic regression. Results: Factor analysis identified three factorial dimensions of compulsive buying tendencies which are impairment of impulse control and reactive or compensatory aspects, reduced rationality according to money spending, and post-purchase guilt. Our results indicated that about 6.7% of the sample shows a compulsive buying pattern, and that females are more affected. For location, a geographic difference between Chongqing and Fuzhou was found for the overall compulsive tendencies, but not for the percentages of compulsive buyers. Conclusions: In sum, the existing study provides evidence that Chinese consumers have a factorial structure which differs somewhat in compulsive buying from Western samples. Observations about gender and location were considered. These findings give a deeper understanding of China’s compulsive buying behavior. PMID:25592309

Visibility and social recognition as psychosocial work environment factors among cleaners in a multi-ethnic workplace intervention.

PubMed

Hviid, Kirsten; Smith, Louise Hardman; Frydendall, Karen Bo; Flyvholm, Mari-Ann

2012-12-24

This article focuses on the psychosocial work environment of immigrant cleaners at a Danish workplace. Today, many cleaners working in Danish cleaning jobs are women from the established immigrant communities, but also labour migrants from the newer EU member states have found their way to the cleaning industry. Studies have drawn attention to immigrants' low position in the cleaning industry and their increased risk of work injuries. This article is based on a case study of an intervention called "Make a Difference" designed to improve the work environment among cleaners at a multi-ethnic workplace. We used semi-structured interviews, photo logs, observation and participation to investigate how the cleaners experienced their work environment. The cleaners reported an overload of heavy work, related to the concept of a classroom's "readiness for cleaning", and they expressed strained social relations and communication in addition to a lack of social recognition and invisibility at the workplace, a school. We analysed these psychosocial work environmental problems by investigating the different forms of social relationships and communication within the group of cleaners, and between the cleaners and the teachers and pupils at the school. Moreover, we discussed why the intervention, based on training of language and cleaning skills and social interaction, only partially improved the cleaners' psychosocial work environment problems. In this article, we argue that social divisions based on ethnicity between the new and the established group of cleaners, combined with their marginal position and poor work organisation at the school, reinforced the cleaners' experiences of psychosocial work environment problems. This article suggests that increased effort towards social inclusion at work and improved work organisation, especially for the new labour migrants from newer EU-countries, should be considered.

Effects of mood state on impulsivity in pathological buying.

PubMed

Nicolai, Jennifer; Darancó, Stefaniá; Moshagen, Morten

2016-10-30

Pathological buying is characterized by irrepressible buying behaviour and its negative consequences. A possible mechanism contributing to its development and maintenance is that buying episodes act as a maladaptive strategy to cope with negative emotions. Accordingly, pathological buying has been repeatedly associated with impulsivity, in particular with the tendency to experience strong reactions under negative affect. Relying on an experimental mood induction procedure, the present study tested in a sample of 100 individuals (a) whether individuals with pathological buying symptoms respond more impulsively in the Go/No-Go Task (as a measure of the behavioural inhibition aspect of impulsivity) and (b) whether this association is more pronounced in a negative mood. While controlling for comorbidities, the results show that pathological buying is associated with faster responses and a larger number of commission errors. Moreover, a significant interaction indicated that the association between pathological buying and performance the Go/No-Go Task was stronger in the negative mood condition. The present study thus shows that pathological buying is associated with deficits in the behavioural inhibition component of impulsivity. These deficits are most pronounced when mood is negative; in turn, this provides an explanation for the occurrence of excessive buying episodes following negative affect.

A randomised controlled trial among cleaners--effects on strength, balance and kinesiophobia.

PubMed

Jørgensen, Marie Birk; Ektor-Andersen, John; Sjøgaard, Gisela; Holtermann, Andreas; Søgaard, Karen

2011-10-10

Cleaners constitute a job group with poor health and low socioeconomic resources. Therefore, there is a great need for scientifically documented health promoting initiatives for cleaners. However, both workplace initiatives and high quality intervention studies are lacking. The aim of this study was to evaluate the effects of a 3-month workplace trial with interventions to improve physical or cognitive behavioural resources among cleaners. A cluster randomised controlled trial was conducted among 294 female cleaners from 9 workplaces. The participants were allocated to three groups: Physical coordination training (PCT, n = 95), Cognitive behavioural theory-based training (CBTr, n = 99) and Reference group (REF, n = 100). Interventions were conducted during work hours for an average of 1 hour/week. Muscle strength was measured by maximal voluntary contractions in trunk/extension, and shoulder abduction/elevation. Postural balance was measured on a force platform. Kinesiophobia was measured with Tampa Scale for Kinesiophobia. Test and questionnaires were completed at baseline and at 3-month follow-up and analyses followed the intention-to-treat (ITT) principle with last observation carried forward in case of missing data at follow-up. Reports and analyses are given on true observations as well. ITT-analyses revealed that PCT improved strength of the trunk (p < .05) and postural balance (p < .05) compared to CBTr and REF. Based on true observations the strength and balance improvements corresponded to ~20% and ~16%, respectively. ITT-analyses showed that CBTr reduced kinesiophobia compared to PCT and REF (p < .05). Based on true observations, the improvement corresponded to a ~16% improvement. This workplace-based intervention study including PCT and CBTr among cleaners improved strength and postural balance from PCT, and kinesiophobia from CBTr. The improved strength, postural balance and kinesiophobia may improve the cleaners' tolerance for high physical work

The medicalization of compulsive buying.

PubMed

Lee, Shirley; Mysyk, Avis

2004-05-01

Compulsive buying has recently been the subject of numerous articles from both consumer research and psychiatric perspectives. Identified by some researchers as a compulsion and by others as an addiction, common solutions to the problem have included drug treatments, participation in self-help groups and cognitive behaviour therapy. The purpose of this article is to examine critically the labelling of compulsive buying in terms of medicalization from the perspective of both medical and non-medical social control of "deviant" consumers. We suggest that the attempt to categorize compulsive buying as an illness represents the ongoing trend to medicalize behavioural problems which may be better understood within the wider context of related phenomena such as the fiscal crisis of the 1980s and 1990s and the consumption-driven economy of North America.

Field evaluation of an engineering control for respirable crystalline silica exposures during mortar removal.

PubMed

Collingwood, Scott; Heitbrink, William A

2007-11-01

During mortar removal with a right angle grinder, a building renovation process known as "tuck pointing," worker exposures to respirable crystalline silica can be as high as 5 mg/m(3), 100 times the recommended exposure limit developed by the National Institute for Occupational Safety and Health. To reduce the risk of silicosis among these workers, a vacuum cleaner can be used to exhaust 80 ft(3)/min (2.26 m(3)/min) from a hood mounted on the grinder. Field trials examined the ability of vacuum cleaners to maintain adequate exhaust ventilation rates and measure exposure outcomes when using this engineering control. These field trials involved task-based exposure measurement of respirable dust and crystalline silica exposures during mortar removal. These measurements were compared with published exposure data. Vacuum cleaner airflows were obtained by measuring and digitally logging vacuum cleaner static pressure at the inlet to the vacuum cleaner motor. Static pressures were converted to airflows based on experimentally determined fan curves. In two cases, video exposure monitoring was conducted to study the relationship between worker activities and dust exposure. Worker activities were video taped concurrent with aerosol photometer measurement of dust exposure and vacuum cleaner static pressure as a measure of airflow. During these field trials, respirable crystalline silica exposures for 22 samples had a geometric mean of 0.06 mg/m(3) and a range of less than 0.01 to 0.86 mg/m(3). For three other studies, respirable crystalline silica exposures during mortar removal have a geometric means of 1.1 to 0.35. Although this field study documented noticeably less exposure to crystalline silica, video exposure monitoring found that the local exhaust ventilation provided incomplete dust control due to low exhaust flow rates, certain work practices, and missing mortar. Vacuum cleaner airflow decrease had a range of 3 to 0.4 ft(3)/min (0.08 to 0.01 m(3)/sec(2)) over a range

The cost of thermographic information obtained by contracting for a service is compared to that of buying equipment and doing the work in-house. A breakeven analysis method is used to find the number of days per year an instrument must be used to justify buying it. Life-cycle costing techniques are used to find the equivalent annual cost of various classes of thermographic instruments. Results indicate that a full-time person earning 20,000 annually must use a 30,000 instrument at least 73 days per year if thermography can otherwise be contracted for $675 per day. By devoting a person to thermography part-time, the number of inspection days for this case can be reduced to about 28. Further in-house advantage can be gained by considering investment tax credits, salvage value and, to some extent, accelerated depreciation. Techniques for finding the breakeven number of inspection days for other costs are developed. A nomogram is included for rapid comparisons.

Make versus buy: a financial perspective.

PubMed

Kisner, Harold J

2003-01-01

Clinical laboratories are often faced with the decision to either perform a service in-house using their own assets or outsource the service to another vendor. This decision affects many aspects of the laboratory's business, from the macroeconomic perspective of outsourcing the laboratory service to a laboratory vendor, to the microeconomics of determining whether to refer a test out to their reference laboratory or perform the test in-house. The basis for decision making includes many variables, but a detailed financial analysis is usually the basis for the decision, especially when the decision only affects the laboratory and not the rest of the institution. Other factors often come into play, and depending on the magnitude, the "make versus buy" decision could be based more on strategic or political factors than economics. Even when noneconomic factors are involved, an effort usually is made to quantify those factors so that the make versus buy decision is reduced to financial terms. The previous article in this issue, "Effectively Managing Your Reference Laboratory Relationship" by Ronald L. Weiss, M.D., focused on the "buy" decision relating to managing the reference laboratory relationship. Although that article took a more clinical perspective through the eyes of the reference laboratory, this article looks at the make versus buy decision from a financial perspective through the eyes of the buying party.

Direct and retrospective assessment of factors contributing to compulsive buying.

Compulsive buying is a disorder that has begun to receive attention from researchers in recent years. The results of a handful of studies suggest that compulsive buying occurs in response to negative emotions and results in a decrease in the intensity of the negative emotions. In this investigation, we used interview and self-monitoring methods to evaluate the antecedents and consequences of compulsive buying in a sample of women who met criteria for compulsive buying on the compulsive buying scale (J. Consumer Res. 19 (1992) 459). As a group, the participants reported negative emotions as the most common antecedents to compulsive buying, and euphoria or relief from the negative emotions as the most common consequence of compulsive buying. These findings were consistent across the interview and self-monitoring assessment methods. The implications for assessment and treatment are discussed.

Experimental evidence for the influence of cognitions on compulsive buying.

PubMed

McQueen, Paul; Moulding, Richard; Kyrios, Michael

Compulsive buying is a disabling condition, where individuals are unable to resist or control their buying behavior, leading to substantial social and financial problems. Cognitive models implicate the role of beliefs as one factor in buying behavior, for example, "this item is unique and will help me improve my life". This study experimentally examined the contribution of such beliefs to the disorder, in individuals who compulsively buy (N = 18) and in non-clinical controls (N = 17). Participants were presented with photographs of idiosyncratically appealing and unappealing items, in the context of imagined scenarios that either minimized or maximized aspects relevant to hypothesized "compulsive buying beliefs" (i.e., beliefs that acquisition can compensate for negative feelings, beliefs regarding uniqueness and lost opportunities, and emotional reasons for buying). It was found that individuals who compulsively buy demonstrated stronger urges to purchase than control participants, regardless of context, but the overall strength of these urges was responsive to manipulations of beliefs about consumer items said to be associated with compulsive buying. The main limitation of the study was a small sample size, potentially reducing power. Nonetheless, these findings provide insights into the processes underlying compulsive phenomena, in particular supporting the role of cognitions in compulsive buying. Copyright © 2014 Elsevier Ltd.

Best Buy: Planning for Disaster

NASA Technical Reports Server (NTRS)

Sachs, Adam; Ellis, Kerry; Sachs, Adam

2008-01-01

When a 1981 tornado in Minnesota revolutionized the retail approach of Sound of Music, which later changed its name to the now very familiar Best Buy, those who founded the company never imagined that a series of hurricanes twenty years later would also help give it a cutting-edge lead in customer service and disaster planning. That original "Tornado Sale'' introduced low prices in a "no-frills" environment that gave the company higher sales than the industry average and paved the way to a new business model. But before Best Buy could find the silver lining of these new storm clouds., it needed to survive them by planning for the destructive weather that plagued Florida during the summer of 2004. Having seen the power of listening to its employees and customers, Best Buy now seeks to capture their thoughts and feedback about other elements of the business.

Swinney, Alison; Fazakerley, Jennifer; McEwan, Neil; Nuttall, Tim

2008-12-01

The aim of this study was to compare the antimicrobial efficacy of ear cleaners against Staphylococcus intermedius, Pseudomonas aeruginosa and Malassezia pachydermatis. Single isolates of each organism were incubated in duplicate at 38 degrees C for 30 min with each ear cleaner diluted 1/2 to 1/256 in phosphate-buffered saline. Positive and negative controls were included. Aliquots were then incubated for 16-18 h on sheep blood agar (bacteria) or for 3 days on Sabouraud's dextrose agar (Malassezia) at 38 degrees C. The lowest dilutions exhibiting 100% antimicrobial efficacy for S. intermedius were: Cleanaural Dog 1/32; Sancerum 1/16; Otoclean 1/4; EpiOtic 1/2; MalAcetic 1/2; and Triz Plus 1/2. The results for P. aeruginosa were Sancerum and Triz Plus 1/16; Cleanaural Dog and EpiOtic 1/8; Otoclean 1/4; and MalAcetic 1/2. Results for M. pachydermatis were: Cleanaural Dog 1/32; Sancerum, Otoclean, EpiOtic and Triz Plus 1/8; and MalAcetic 1/4. Cleanaural Cat, MalAcetic HC and Triz EDTA did not display any antimicrobial activity at any dilution. Antimicrobial activity appeared to be associated with the presence of isopropyl alcohol, parachlorometaxylenol and a low pH. The results of this study may help clinicians make evidence-based decisions when selecting ear cleaners for use in individual cases.

Visibility and Social Recognition as Psychosocial Work Environment Factors among Cleaners in A Multi-Ethnic Workplace Intervention

2012-01-01

This article focuses on the psychosocial work environment of immigrant cleaners at a Danish workplace. Today, many cleaners working in Danish cleaning jobs are women from the established immigrant communities, but also labour migrants from the newer EU member states have found their way to the cleaning industry. Studies have drawn attention to immigrants’ low position in the cleaning industry and their increased risk of work injuries. This article is based on a case study of an intervention called “Make a Difference” designed to improve the work environment among cleaners at a multi-ethnic workplace. We used semi-structured interviews, photo logs, observation and participation to investigate how the cleaners experienced their work environment. The cleaners reported an overload of heavy work, related to the concept of a classroom’s “readiness for cleaning”, and they expressed strained social relations and communication in addition to a lack of social recognition and invisibility at the workplace, a school. We analysed these psychosocial work environmental problems by investigating the different forms of social relationships and communication within the group of cleaners, and between the cleaners and the teachers and pupils at the school. Moreover, we discussed why the intervention, based on training of language and cleaning skills and social interaction, only partially improved the cleaners’ psychosocial work environment problems. In this article, we argue that social divisions based on ethnicity between the new and the established group of cleaners, combined with their marginal position and poor work organisation at the school, reinforced the cleaners’ experiences of psychosocial work environment problems. This article suggests that increased effort towards social inclusion at work and improved work organisation, especially for the new labour migrants from newer EU-countries, should be considered.

Duration of employment is not a predictor of disability of cleaners: a longitudinal study.

Cleaning is a high-risk occupation for developing musculoskeletal disorders. Sickness absence is twice as high as in other occupations. Disability pensions for musculoskeletal disorders are twice as high in cleaners as in other employed women. However, a result from Norwegian and Danish studies shows that female cleaners do not report higher morbidity of musculoskeletal disorders than other women. The objective was to analyse whether female cleaners have a higher risk of obtaining a disability pension than women in other unskilled occupations and whether the length of employment influences the risk. The material is from the National Census in 1980 and 1990 and supplemented with disability pensioning data from the National Insurance Administration and the Population registry. Women aged 20-49, working as cleaners, seamstresses, nursing, kitchen, or shop assistants in 1980 were followed until 1990 or until receiving disability pension. Female cleaners aged 30-59 years in 1990 were categorized into two cohorts by occupation in 1980. They were followed from 1991 to 1994, to the date they died, or received disability pension. Incidence rates and incidence rate ratio for disability pension and mortality was calculated by Poisson regression. Cox regression calculated the relative risk of obtaining disability pension. Disability pension rates were higher among cleaners than among other women in unskilled occupations (1.4 per 1,000 person years (CI 95% 1.35-1.46)), but the risk of obtaining disability pension did not increase with increasing exposure to cleaning (HR 0.8 (CI 95% 0.6-1.2)). The cleaning occupation has high disability rates compared with other unskilled occupations. A contribution factor to these high rates is a selection of women with poor health into the occupation.

Do air cleaners make a difference in treating allergic disease in homes?

PubMed

Reisman, R E

2001-12-01

The purpose of this review is to objectively critique available data regarding the clinical benefits of room air cleaners and to provide physicians and patients with a reasonable recommendation of their utility in treatment of inhalant allergic disease. Data were obtained from published studies and reviews. The specific reviewed studies met the following criteria: 1) selection of patients with clinical allergic disease confirmed by detection of allergen-specific immunoglobulin E; 2) use of an effective air filter; 3) clinical and laboratory evaluation of results; and 4) measurement of the results of air filtration on environmental allergen or airborne particulate levels. The studies were conducted in a double-blind manner. Conclusions of two previous reviews are also incorporated in this paper. The results of the published studies and summary reviews show minimal, if any, effectiveness of room air cleaners in treatment of allergic respiratory disease. Room air cleaners should not be recommended for people with inhalant allergic disease.

Psychiatric and socioeconomic aspects as possible predictors of compulsive buying behavior.

PubMed

Leite, Priscilla Lourenço; Silva, Adriana Cardoso

2016-01-01

Compulsive buying can be characterized as an almost irresistible urge to buy various items. Compulsive buying disorder is a subject of growing interest to health professionals. It is a current issue and the prevalence rate in the global population is around 5 to 8%. The main objective of this study was to identify predictors of compulsive buying in the Brazilian population, assessing possible relationships between compulsive buying, depression and anxiety. The Richmond Compulsive Buying Scale was administered to screen for compulsive buying and the Hospital Anxiety and Depression Scale was used to assess anxiety and depression in a sample of 359 participants. Pearson coefficients were used to test for correlations. Our study identified an interaction between female gender and compulsion to purchase. Furthermore, people's occupations also appear to have an influence on the problem. We found a correlation between depressive symptoms and oniomania. Our study has certain limitations, such as the difficulty in recruiting individuals with compulsive buying disorder. Since compulsive buying is a phenomenon that is seldom investigated, it therefore remains unidentified. However, this is nevertheless a pioneering paper on the Brazilian population.

Compulsive buying: relationship with body mass index.

PubMed

Sansone, Randy A; Chang, Joy; Jewell, Bryan; Marion, Brandee E

2013-01-01

Compulsive buying has historically been associated with various self-regulatory disturbances, including eating pathology (e.g., binge eating). Therefore, a relationship between scores on a measure of compulsive buying, the Compulsive Buying Scale (CBS), and body mass index (BMI) in adulthood was hypothesized. Using a self-report survey methodology in a cross-sectional consecutive sample of convenience of 373 obstetrics/gynecology patients, correlations between CBS scores and BMI, both generally and with regard to race were examined. A modest general correlation between CBS scores and BMI (r = 0.17, P < 0.01) was found. However, when these data were examined by race, CBS scores and BMI were significantly related among Caucasian women (r = 0.25, P < 0.01), but not in African American women (r = 0.04, P = n.s.). Findings indicate that compulsive buying is associated with increasing BMI in adulthood, particularly among Caucasian women. Copyright © 2013 The Obesity Society.

Compulsive buying disorder: a review of the evidence.

PubMed

Black, Donald W

2007-02-01

Compulsive buying disorder is characterized by excessive or poorly controlled preoccupations, urges, or behaviors regarding shopping and spending that lead to subjective distress or impaired functioning. Compulsive buying disorder is estimated to have a lifetime prevalence of 5.8% in the United States general adult population. In clinical settings, most individuals with compulsive buying disorder are women (approximately 80%). This gender difference may be artifactual. Compulsive buying disorder is typically chronic or intermittent, with an age of onset in the late teens or early 20s. Comorbid mood and anxiety disorders, substance use disorders, eating disorders, and other disorders of impulse control are common, as are Axis II disorders. The disorder occurs worldwide, mainly in developed countries with market-based economies, and it tends to run in families with mood disorders and substance abuse. There is no standard treatment for compulsive buying disorder, but group cognitive-behavioral models seem promising, and psychopharmacologic treatments are being actively studied. Other treatment options include simplicity circles, 12-step programs, financial counseling, bibliotherapy, marital therapy, and financial counseling. Directions for future research are discussed.

Around the world, increases in wealth have produced an unintended consequence: a rising sense of time scarcity. We provide evidence that using money to buy time can provide a buffer against this time famine, thereby promoting happiness. Using large, diverse samples from the United States, Canada, Denmark, and The Netherlands ( n = 6,271), we show that individuals who spend money on time-saving services report greater life satisfaction. A field experiment provides causal evidence that working adults report greater happiness after spending money on a time-saving purchase than on a material purchase. Together, these results suggest that using money to buy time can protect people from the detrimental effects of time pressure on life satisfaction.

Regenerating using aqueous cleaners with ozone and electrolysis

NASA Technical Reports Server (NTRS)

Mcginness, Michael P.

1994-01-01

A new process converts organic oil and grease contaminates in used water based cleaners into synthetic surfactants. This permits the continued use of a cleaning solution long after it would have been dumped using previously known methods. Since the organic soils are converted from contaminates to cleaning compounds the need for frequent bath dumps is totally eliminated. When cleaning solutions used in aqueous cleaning systems are exhausted and ready for disposal, they will always contain the contaminates removed from the cleaned parts and drag-in from prior cleaning steps. Even when the cleaner is biodegradable these contaminants will frequently cause the waste cleaning solution to be a hazardous waste. Chlorinated solvents are rapidly being replaced by aqueous cleaners to avoid the new ozone-depletion product-labeling-law. Many industry standard halocarbon based solvents are being completely phased out of production, and their prices have nearly tripled. Waste disposal costs and cradle-to-grave liability are also major concerns for industry today. This new process reduces the amount of water and chemicals needed to maintain the cleaning process. The cost of waste disposal is eliminated because the water and cleaning compounds are reused. Energy savings result by eliminating the need for energy currently used to produce and deliver fresh water and chemicals as well as the energy used to treat and destroy the waste from the existing cleaning processes. This process also allows the cleaning bath to be maintained at the peak performance of a new bath resulting in decreased cycle times and decreased energy consumption needed to clean the parts. This results in a more efficient and cost effective cleaning process.

Compulsive buying is defined by the presence of repetitive impulsive and excessive buying, leading to personal and family distress. The objective of this study is to assess the prevalence of compulsive buying among "normal consumers" and to describe the specificities in the buying style of compulsive buyers. We tried to answer several questions. (1) Does compulsive buying occur more often during sales or periods of sales campaigns? (2) Is compulsive buying more impulsive and unplanned than normal buying? (3) Are compulsive buyers more "affectively" involved in their purchases (preference for specific brands they have a narcissistic relationship with, tendency to consider purchases as exceptional special occasions)? (4)Do women who buy compulsively use shopping Web sites and the Internet in general more than controls? We interviewed 200 women successively entering Les Galeries Lafayette, a famous Parisian department store. We diagnosed compulsive buying with standardized criteria and a specific rating scale. All subjects answered an additional questionnaire assessing their buying behavior. We also rated their duration of connection to the Web, the number of e-mails sent and received, and the time spent speaking on a cellular phone. Prevalence of compulsive buying was 32.5%. The proportion of married women was lower among compulsive buyers (66%) than in controls (85%). Compulsive buyers do not seek sales more than controls. Their decision to buy is more often made during their stay in the shop (48% vs 24%, chi(2) = 117, P < .001). Women buying compulsively consider more often their purchases as opportunities not to be passed by (33.7% vs 23.1%, P = .006). They have a higher tendency to use items less than expected (23.4% vs 14.4% in the control group, P < .001). They more often make purchases to impress others (6.5% vs 2.5%, P = .04) and consider more often their purchases as personally gratifying (44% vs 23%, P < .001). Their connections to online shopping sites are

Informal employment is common in developing countries, including Egypt. This type of employment may have significant consequences on mental health. To determine the prevalence and risk factors of common mental disorders and substance abuse among temporary hired hospital cleaners. A cross-sectional study was conducted on 242 adult temporary cleaners and 209 permanent cleaners working in 4 governmental hospitals in Zagazig City, Sharqia Governorate, Egypt. All participants were invited to complete a structured questionnaire through a semi-structured interview which included the self-reporting questionnaire 20 items (SRQ-20) and the work stress scale. Assessment of drug use included urine-based screening tests for common substances abused. The prevalence of job stress, common mental disorders and substance abuse, particularly tramadol and cannabis (Bango), was significantly higher in the studied temporary cleaners compared to permanent cleaners. Risk factors associated with increased susceptibility of the temporary cleaners to common mental disorders were family history of substance abuse, high crowding index, history of physical illness, low educational level, and smoking; while being unmarried, male sex, family history of mental disorder, age ≥40 years, smoking, and length of service ≥8 years, were associated with substance abuse among the same group. Temporary hired hospital cleaners suffered from impaired mental health more than permanent cleaners. Therefore, expanding the coverage of current laws and occupational safety and health standards to cover workers in the informal sector especially in developing countries is recommended.

Compulsive buying tendencies and personal finances.

In a community sample of 225 adults, scores on the Compulsive Buying Scale were associated with scores on the subscales of the Executive Personal Finance Scale (rs = -.35 to -.70) and the Money Attitudes Scale (positively with using money for impressing others, and negatively with saving and planning). The results suggested that common tendencies toward compulsive buying may not be pathological, but merely associated with attitudes toward money in general and financial management habits.

Design and prototype tests of a seismic attenuation system for the advanced-LIGO output mode cleaner

Bertolini, A.; DeSalvo, R.; Galli, C.; Gennaro, G.; Mantovani, M.; Márka, S.; Sannibale, V.; Takamori, A.; Torrie, C.

2006-04-01

Both present LIGO and advanced LIGO (Ad-LIGO) will need an output mode cleaner (OMC) to reach the desired sensitivity. We designed a suitable OMC seismically attenuated optical table fitting to the existing vacuum chambers (horizontal access module, HAM chambers). The most straightforward and cost-effective solution satisfying the Ad-LIGO seismic attenuation specifications was to implement a single passive seismic attenuation stage, derived from the 'seismic attenuation system' (SAS) concept. We built and tested prototypes of all critical components. On the basis of these tests and past experience, we expect that the passive attenuation performance of this new design, called HAM-SAS, will match all requirements for the LIGO OMC, and all Ad-LIGO optical tables. Its performance can be improved, if necessary, by implementation of a simple active attenuation loop at marginal additional cost. The design can be easily modified to equip the LIGO basic symmetric chamber (BSC) chambers and leaves space for extensive performance upgrades for future evolutions of Ad-LIGO. Design parameters and prototype test results are presented.

[The application of ecological momentary assessment to the study of compulsive buying].

2008-12-01

Although compulsive buying is a disorder that has begun to receive attention from researchers in recent years, relatively little is known about the relationship between compulsive buying, mood, and daily stressful events. In our pilot study ecological momentary assessment (EMA) was used to examine the described relationships for the first time. 26 patients, who met criteria for compulsive buying, self-monitored their pathological behaviour, their momentary mood and the occurrence of stressful events four times a day on a handheld computer for a period of two weeks. On days with excessive buying behaviour patients reported significantly more daily stressful events compared to days without pathological buying. Before the buying episode patients recorded significantly more positive emotions. The most common consequence of compulsive buying was a significant decrease of positive affects. Thus the results of the current study suggest that mood states and daily stressful events are associated with compulsive buying behaviour. Although mood got worse immediately after excessive buying, this negative consequence did not reduce the frequency of pathological behaviour. This could implicate a high presence-orientation and impulsivity of the patients.

Determining the EDTA Content in a Consumer Shower Cleaner. An Introductory Chemistry Laboratory Experiment

At Altoona College, Chemistry 11 is offered to students as a preparatory course for the University's Chemical Principles course, Chem 12. A relevant laboratory is a source of motivation for the students to learn the chemistry. One way of making the laboratory relevant is to analyze the chemical components of consumer products. Several new shower-cleaning products have been introduced, which advertise that cleaning the shower is no longer necessary. The cleaners work using a combination of surfactants, alcohols, and a chelating agent. The Web site of a popular shower cleaner lists EDTA (ethylenediamine tetraacetate ion) as the chelating agent. The classic EDTA/calcium complexometric titration can be used to determine the EDTA content of the cleaner. This article describes the experiment to determine the EDTA content in a shower-cleaning product.

The benefits of introducing active learning in college science courses are well established, yet more needs to be understood about student buy-in to active learning and how that process of buy-in might relate to student outcomes. We test the exposure–persuasion–identification–commitment (EPIC) process model of buy-in, here applied to student (n = 245) engagement in an undergraduate science course featuring active learning. Student buy-in to active learning was positively associated with engagement in self-regulated learning and students’ course performance. The positive associations among buy-in, self-regulated learning, and course performance suggest buy-in as a potentially important factor leading to student engagement and other student outcomes. These findings are particularly salient in course contexts featuring active learning, which encourage active student participation in the learning process. PMID:27909026

This article provides relevant results of a cleaner production program conducted in a company dedicated to remanufacturing air compressors in the city of Hermosillo, Sonora, Mexico. The overall study design was based on an integration of acknowledged cleaner production and pollution prevention programs. Although this kind of program also involves environmental issues, this study focused on occupational health and safety by addressing different aspects of the work environment: ergonomic, physical (noise and lighting), and chemical. Particularly, ergonomic aspects were evaluated through the Modular Arrangement of Predetermined Time Standards (MODAPTS) method. For physical aspects, noise and lighting were addressed through Standard No. NOM-011-STPS-2001 and Standard No. NOM-025-STPS-2008 respectively. In addition, chemical aspects were analyzed through material safety data sheets and different search tools. Root causes of each risk were identified, and options to prevent, eliminate, and/or reduce each risk have been provided.

[A case of compulsive buying--impulse control disorder or dependence disorder?].

PubMed

Croissant, Bernhard; Klein, Oliver; Löber, Sabine; Mann, Karl

2009-05-01

It is unclear what disease entity causes compulsive buying. In ICD-10 and DSM-IV, compulsive buying is classified as "Impulse control disorder--not otherwise classified". Some publications interpret compulsive buying rather as a dependence disorder. We present the case of a male patient with compulsive buying syndrome. We discuss the close relationship to dependence disorders. The patient showed symptoms which would normally be associated with a dependence disorder. On the basis of a wider understanding of the dependency concept, as it is currently being discussed, we believe that the patient has shown a typical buying behavior that has presumably activated a reward loop similar to that of a substance dependency.

[What characterizes companies that buy private health insurance?].

PubMed

Seim, Asbjørn; Løvaas, Linda; Hagen, Terje P

2007-10-18

Starting from a very low level, the number of Norwegian companies and individuals that buy private health insurance has increased during recent years. We ask: What characterizes companies that buy private health insurance? Data were collected through a postal survey to 2,500 companies with two or more employees during the spring of 2005. The response rate was 0.43. The probability of buying health insurance was analyzed by means of logistic regression. More than 80,000 individuals, or approximately 1.8% of the Norwegian population, bought private health insurance by the beginning of 2007. 75% were insured through collective insurance contracts through companies, while the rest had bought individual policies. The number of employees holding private health insurance through their employer comprised 2.5% of the total workforce. The probability for companies to buy private health insurance increased with the firm's profitability, by the share of younger employees and with the employees' average level of education. The probability of buying private health insurance is higher in branches with increased health risk such as agriculture and forestry, mining, building and constructions than in low risk branches. We assume that future demand for private health insurance in Norway will depend on the tax incentives, waiting time to elective treatment and the companies' profit margins.

Negative and positive urgency may both be risk factors for compulsive buying

PubMed Central

ROSE, PAUL; SEGRIST, DANIEL J.

2014-01-01

Background and aims: Descriptions of compulsive buying often emphasize the roles of negative moods and trait impulsivity in the development of problematic buying habits. Trait impulsivity is sometimes treated as a unidimensional trait in compulsive buying research, but recent factor analyses suggest that impulsivity consists of multiple components that are probably best treated as independent predictors of problem behavior. In order to draw greater attention to the role of positive moods in compulsive buying, in this study we tested whether negative urgency (the tendency to act rashly while in negative moods) and positive urgency (the tendency to act rashly while in positive moods) account for similar amounts of variance in compulsive buying. Methods: North American adults (N = 514) completed an online survey containing the Richmond Compulsive Buying Scale (Ridgway, Kukar-Kinney & Monroe, 2008), established measures of positive and negative urgency (Cyders et al., 2007), ad hoc measures of buying-specific positive and negative urgency, measures of extraversion and neuroticism obtained from the International Personality Item Pool (http://ipip.ori.org/), and demographic questions. Results: In several multiple regression analyses, when demographic variables, neuroticism, and extraversion were controlled, positive urgency and negative urgency both emerged as significant predictors of compulsive buying. Whether the two urgency variables were domain-general or buying-specific, they accounted for similar amounts of variance in compulsive buying. Conclusions: Preventing and reducing compulsive buying may require attention not only to the purchasing decisions people make while in negative states, but also to the purchasing decisions they make while in positive states.

To test an air cleaner and health coach intervention to reduce secondhand smoke exposure compared with air cleaners alone or no air cleaners in reducing particulate matter (PM), air nicotine, and urine cotinine concentrations and increasing symptom-free days in children with asthma residing with a smoker. Randomized controlled trial, with randomization embedded in study database. The Johns Hopkins Hospital Children's Center and homes of children. Children with asthma, residing with a smoker, randomly assigned to interventions consisting of air cleaners only (n = 41), air cleaners plus a health coach (n = 41), or delayed air cleaner (control) (n = 44). Changes in PM, air nicotine, and urine cotinine concentrations and symptom-free days during the 6-month study. The overall follow-up rate was high (91.3%). Changes in mean fine and coarse PM (PM(2.5) and PM(2.5-10)) concentrations (baseline to 6 months) were significantly lower in both air cleaner groups compared with the control group (mean differences for PM(2.5) concentrations: control, 3.5 μg/m(3); air cleaner only, -19.9 μg/m(3); and air cleaner plus health coach, -16.1 μg/m(3); P = .003; and PM(2.5-10) concentrations: control, 2.4 μg/m(3); air cleaner only, -8.7 μg/m(3); and air cleaner plus health coach, -10.6 μg/m(3); P = .02). No differences were noted in air nicotine or urine cotinine concentrations. The health coach provided no additional reduction in PM concentrations. Symptom-free days were significantly increased [corrected] in both air cleaner groups compared with the control group (P = .03). Although the use of air cleaners can result in a significant reduction in indoor PM concentrations and a significant increase in symptom-free days, it is not enough to prevent exposure to secondhand smoke.

The shopping brain: math anxiety modulates brain responses to buying decisions.

PubMed

Jones, William J; Childers, Terry L; Jiang, Yang

2012-01-01

Metacognitive theories propose that consumers track fluency feelings when buying, which may have biological underpinnings. We explored this using event-related potential (ERP) measures as twenty high-math anxiety (High MA) and nineteen low-math anxiety (Low MA) consumers made buying decisions for promoted (e.g., 15% discount) and non-promoted products. When evaluating prices, ERP correlates of higher perceptual and conceptual fluency were associated with buys, however only for High MA females under no promotions. In contrast, High MA females and Low MA males demonstrated greater FN400 amplitude, associated with enhanced conceptual processing, to prices of buys relative to non-buys under promotions. Concurrent late positive component (LPC) differences under no promotions suggest discrepant retrieval processes during price evaluations between consumer groups. When making decisions to buy or not, larger (smaller) P3, sensitive to outcome responses in the brain, was associated with buying for High MA females (Low MA females) under promotions, an effect also present for males under no promotions. Thus, P3 indexed decisions to buy differently between anxiety groups, but only for promoted items among females and for no promotions among males. Our findings indicate that perceptual and conceptual processes interact with anxiety and gender to modulate brain responses during consumer choices. Copyright © 2011 Elsevier B.V.

The aims of this study were to examine the associations between compulsive buying and quality of life and to estimate the monetary cost of compulsive buying for a cohort of men and women at mean age 43. Participants came from a community-based random sample of residents in two New York counties (N=548). The participants were followed from adolescence to early midlife. The mean age of participants at the most recent interview was 43.0 (SD=2.8). Fifty five percent of the participants were females. Over 90% of the participants were white. Linear regression analyses showed that compulsive buying was significantly associated with quality of life, despite controlling for relevant demographic and psychosocial factors. The estimated monetary cost of compulsive buying for this cohort was significant. The fact that the monetary cost of CB is not trivial suggests that individuals are both consciously and unconsciously plagued by their CB. The findings are important for interventionists and clinicians for cost-effective intervention and treatment programs. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Stimulation of dopamine D₁ receptor improves learning capacity in cooperating cleaner fish.

PubMed

Messias, João P M; Santos, Teresa P; Pinto, Maria; Soares, Marta C

2016-01-27

Accurate contextual decision-making strategies are important in social environments. Specific areas in the brain are tasked to process these complex interactions and generate correct follow-up responses. The dorsolateral and dorsomedial parts of the telencephalon in the teleost fish brain are neural substrates modulated by the neurotransmitter dopamine (DA), and are part of an important neural circuitry that drives animal behaviour from the most basic actions such as learning to search for food, to properly choosing partners and managing decisions based on context. The Indo-Pacific cleaner wrasse Labroides dimidiatus is a highly social teleost fish species with a complex network of interactions with its 'client' reef fish. We asked if changes in DA signalling would affect individual learning ability by presenting cleaner fish two ecologically different tasks that simulated a natural situation requiring accurate decision-making. We demonstrate that there is an involvement of the DA system and D1 receptor pathways on cleaners' natural abilities to learn both tasks. Our results add significantly to the growing literature on the physiological mechanisms that underlie and facilitate the expression of cooperative abilities. © 2016 The Author(s).

Ozone can cause many health problems, including exacerbation of asthma, throat irritation, cough, chest ache, shortness of breath, and respiratory infections. Air cleaners are one of the sources of indoor ozone, and thus the evaluation of ozone generated by air cleaners is desired significant issue. Most evaluation methods proposed are based on chamber tests. However, the adsorption and desorption of ozone on the wall of test chamber and the deposition of ozone resulted from the surface reaction can influence the evaluation results. In this study, we developed a mass balance model that took the adsorption, desorption and deposition of ozone into consideration to evaluate the effective ozone emission rates of six selected air cleaners. The experiments were conducted in a stainless steel chamber with a volume of 11.3 m 3 at 25 °C and 60% relative humidity. The adsorption, desorption and deposition rate constants of ozone obtained by fitting the model to the experimental data were k a = 0.149 ± 0.052 m h -1, k d = 0.013 ± 0.007 h -1, and k r = 0.050 ± 0.020 h -1, respectively. The effective ozone emission rates of Air Cleaners No. 1, 2, and 3 ranged between 13,400-24,500 μg h -1, 7190-10,400 μg h -1, and 4880-6560 μg h -1, respectively, which were more stable than those of No.4, 5, and 6. The effective ozone emission rates of Air Cleaners No. 4, 5, and 6 increased with the time of operation which might be relevant to the decrease of ozone removal by the "aging" filter installed in these cleaners. The removal of toluene and formaldehyde by these six air cleaners were also evaluated and the clean air delivery rates (CADRs) of these two pollutants ranged from non-detectable to 0.42 ± 0.08 m 3 h -1, and from non-detectable to 0.75 ± 0.07 m 3 h -1, respectively. The CADRs showed an insignificant relationship with the effective ozone emission rates. Thus, the removal of toluene and formaldehyde might be resulted from the adsorption on the filters and the

Finally, possible extensions of the research to the area of adolescents' impulsive buying are suggested.

Lasers and aesthetic procedures have transformed dermatology practice. They have aided in the treatment of hitherto untreatable conditions and allowed better financial remuneration to the physician. The availability of a variety of laser devices of different makes, specifications and pricing has lead to confusion and dilemma in the mind of the buying physician. There are presently no guidelines available for buying a laser. Since purchase of a laser involves large investments, careful consideration to laser specifications, training, costing, warranty, availability of spares, and reliability of service are important prerequisites. This article describes various factors that are needed to be considered and also attempts to lay down criteria to be assessed while buying a laser system that will be useful to physicians before investing in a laser machine. Meticulous planning of the type of machine, specifications, financial aspects, maintenance and warranties is important.It is wise to sign a contract or agreement between the buyer and seller before purchase of a laser which covers key aspects of installation, after sales service and maintenance of the machine.Adequate training is essential; understanding laser physics and laser-tissue interaction goes a long way in getting the best out of the machine.The credibility of the dealer and company should be ascertained in order to be assured of after-sales service.Buying used machines, sharing of equipment to offset high initial investments is a good option but even more care is required to ensure proper functioning and maintenance.

Research on the Problem and Countermeasures of Group-Buying

Dong, Yahui; Li, Wei; Cheng, Limin

The threshold of group-buying is low, so the group-buying develops very fast. But at the same time, there are many goods which have low price and high quality service which is false to get the network users' trust. Therefore, consumers should keep a clear head and avoiding straying into the trap of business, the website of group-buying should strengthen self-construction to safeguard the consumers' interest. In addition, government needs to play its due role to protect the legitimate right of the consumers.

Brook, Judith S.; Zhang, Chenshu; Brook, David W.; Leukefeld, Carl G.

2015-01-01

This longitudinal study examined the association between psychosocial antecedents, including illicit drug use, and adult compulsive buying (CB) across a 29-year time period from mean age 14 to mean age 43. Participants originally came from a community-based random sample of residents in two upstate New York counties. Multivariate linear regression analysis was used to study the relationship between the participant’s earlier psychosocial antecedents and adult CB in the fifth decade of life. The results of the multivariate linear regression analyses showed that gender (female), earlier adult impulse buying (IB), depressive mood, illicit drug use, and concurrent ADHD symptoms were all significantly associated with adult CB at mean age 43. It is important that clinicians treating CB in adults should consider the role of drug use, symptoms of ADHD, IB, depression, and family factors in CB. PMID:26165963

To study on vacuum force, we must clear what is vacuum, vacuum is a space do not have any air and also ray. There is not exist an absolute the vacuum of space. The vacuum of space is relative, so that the vacuum force is relative. There is a certain that vacuum vacuum space exists. In fact, the vacuum space is relative, if the two spaces compared to the existence of relative vacuum, there must exist a vacuum force, and the direction of the vacuum force point to the vacuum region. Any object rotates and radiates. Rotate bend radiate- centripetal, gravity produced, relative gravity; non gravity is the vacuum force. Gravity is centripetal, is a trend that the objects who attracted wants to Centripetal, or have been do Centripetal movement. Any object moves, so gravity makes the object curve movement, that is to say, the radiation range curve movement must be in the gravitational objects, gravity must be existed in non vacuum region, and make the object who is in the region of do curve movement (for example: The earth moves around the sun), or final attracted in the form gravitational objects, and keep relatively static with attract object. (for example: objects on the earth moves but can't reach the first cosmic speed).

2017-12-01

Cleaner organisms perform key functional roles in reducing rates of parasitism in marine communities. Pederson cleaner shrimps Ancylomenes pedersoni are major cleaners of reef fishes in the tropical western Atlantic and form obligate symbioses with host sea anemones. Information about their life-history traits would contribute to understanding how symbiosis impacts life-history evolution in crustaceans, but little is known about patterns of growth and reproduction in this anemone shrimp. We quantified growth, sexual reproduction, senescence, and mortality in individuals of A. pedersoni under laboratory conditions and their abundance and population size structure on coral reefs in St. Thomas, U.S. Virgin Islands. Von Bertalanffy growth curves were fitted to the data to determine age-size relationships, and the Beverton-Holt model was used to estimate mortality rates and size at maximum yield. Individuals grew rapidly when young, then slowed their growth after reaching sexual maturity at ~6 months. Individuals were gonochoric, with males attaining significantly smaller body sizes and shorter life spans than did females. Prior to death at <2 years, members of both genders exhibited senescence during which they ceased reproducing, shrank (females only), and decreased their activity levels over ~1-4 weeks. Field populations were abundant and composed mostly of juveniles during both years examined. Populations appeared to be stable but highly dynamic in terms of individuals, reaching maximum yield at 4 months of age. We conclude that obligate symbiosis with large sea anemones and cleaner mutualism with reef fishes both contribute to explaining aspects of the life history of Pederson shrimps, especially their apparent mating system of pure-search polygynandry. This life-history information also provides a scientific basis for sustainable fishery management and aquaculture of this key coral reef organism.

Social relationships are crucially dependent on individual ability to learn and remember ecologically relevant cues. However, the way animals recognize cues before engaging in any social interaction and how their response is regulated by brain neuromodulators remains unclear. We examined the putative involvement of arginine vasotocin (AVT) and isotocin (IT), acting at different brain regions, during fish decision-making in the context of cooperation, by trying to identify how fish distinguish and recognize the value of other social partners or species. We hypothesized that the behavioural responses of cleaner fish clients to different social contexts would be underlain by changes in brain AVT and IT levels. We have found that changes in AVT at the level of forebrain and optic tectum are linked with a response to allopatric cleaners (novel or unfamiliar stimuli) while those at cerebellum are associated with the willingness to be cleaned (in response to sympatric cleaners). On the other hand, higher brain IT levels that were solely found in the diencephalon, also in response to allopatric cleaners. Our results are the first to implicate these nonapeptides, AVT in particular, in the assessment of social cues which enable fish to engage in mutualistic activities. PMID:28683143

Cue-induced craving in pathological buying: empirical evidence and clinical implications.

PubMed

Trotzke, Patrick; Starcke, Katrin; Pedersen, Anya; Brand, Matthias

2014-01-01

Pathological buying is associated with marked distress and impaired functioning in important life domains. It is currently under debate whether pathological buying can be considered a behavioral addiction. In analogy to results reported in addicted individuals, craving reactions elicited by addiction-related cues might be an underlying mechanism for the etiology and pathogenesis of pathological buying. In the present study, 30 pathological buyers and 30 matched control participants were examined with a cue-reactivity paradigm consisting of shopping and control cues. Skin conductance responses, as well as subjective ratings for arousal, valence, and urge to buy, were assessed. Subjective craving reactions were measured before and after the cue-reactivity paradigm. On a physiological level, skin conductance responses toward shopping cues were higher in pathological buyers (mean [M; standard deviation {SD}] = 0.26 [0.13]) compared with control participants (M [SD] = 0.19 [0.09]; t(58) = 2.29, p = .025, d = 0.60). On a behavioral level, the individuals with pathological buying rated the shopping cues as more arousing and more positive, and reported a greater urge to buy compared with control participants and with control cues. An increase in subjective craving after completing the cue-reactivity paradigm was observed only in the pathological buyers (Mpre [SD] = 1.95 [1.47], Mpost [SD] = 2.87 [1.79]; t(29) = 5.07, p < .001, d = 0.97). Cue-reactivity and craving might be potential correlates for the development and maintenance of pathological buying. The results demonstrate similarities between pathological buying and substance or behavioral addictions and provide implications for clinical treatment.

This study assessed the risk of dermatitis, urticaria and loss of skin barrier function in 425 cleaners and 281 reference workers (retail workers and bus drivers). Symptoms, atopy and skin barrier function were assessed by questionnaire, skin prick tests, and measurement of transepidermal water loss. Cleaners had an increased risk of current (past 3 months) hand/arm dermatitis (14.8% vs. 10.0%; OR = 1.9, p < 0.05) and urticaria (11% vs. 5.3%; OR = 2.4, p < 0.05) and were more likely to have dermatitis as adults (17.6% vs. 11.4%; OR = 1.8, p < 0.05). The risk of atopy was not increased, but associations with symptoms were more pronounced in atopics. Transepidermal water loss was significantly higher in cleaners. Wet-work was a significant risk factor for dermatitis and hand washing and drying significantly reduced the risk of urticaria. In conclusion, cleaners have an increased risk of hand/arm dermatitis, urticaria and loss of skin barrier function.

A cleaner production approach to urban water management: potential for application in Harare, Zimbabwe

NASA Astrophysics Data System (ADS)

Nhapi, Innocent; Hoko, Zvikomborero

Water quality is an urgent problem in the Lake Chivero catchment, Zimbabwe, whilst water scarcity will be a problem soon. This study focused on assessing the potential impacts of the application of cleaner production principles in urban water supply and sanitation in the context of sustainable management of water resources. The cleaner production principles are explained together with how they can be applied to urban water management. Data from City of Harare and previous studies were collected and analysed. The study focused mainly on water, nitrogen and phosphorus. About 304,000 m 3/d of wastewater, containing 30,000 kg/d TN and 3600 kg/d TP are currently produced and treated at five sewage treatment works in Harare. Water conservation, treatment and reuse strategies were developed for different land uses starting from water-saving devices, regulation, leak detection and repair, to wastewater treatment and reuse. This study showed that the application of the cleaner production principles would reduce total wastewater production from 487,000 m 3/d to 379,000 m 3/d (a 27% reduction) based on year 2015 projections. A very large investment in treatment infrastructure can be postponed for about 10 years. In terms of amounts treated and discharged at central level this translates to reductions of 47% on flows, 34% on TN, and 44% on TP. River discharges can be eliminated. It was concluded that a cleaner production approach could substantially reduce current water pollution and long-term scarcity problems in Harare.

2008-05-01

Compulsive buying disorder was first described as a psychiatric syndrome in the early twentieth century. Its classification remains elusive, and investigators have debated its potential relationship to mood, substance use, obsessive-compulsive, and impulse control disorders. The objective of this study is to present a review of compulsive buying disorder and present a case vignette. Two databases were reviewed (Medline and PsycINFO) in search for articles published in the last 40 years. Selected terms included oniomania, compulsive buying, and compulsive shopping. Other relevant articles were also identified through reference lists. Compulsive buying disorder is a prevalent and chronic condition that is found worldwide, sharing commonalities with impulse control disorders. In clinical samples, women make up more than 80% of subjects. Its etiology is unknown, but neurobiologic and genetic mechanisms have been proposed. The disorder is highly comorbid with mood, substance use, eating and impulse control disorders. Treatment recommendations derived from the literature and clinical experience suggest that problem shoppers can benefit from psychosocial interventions. Cognitive-behavioral group models appear promising. Medication trials have reported mixed results. The identification and treatment of psychiatric comorbidity is also a key aspect of treatment. In order to determine the validity of compulsive buying disorder, future work should focus on psychopathology and neurobiological findings unique to the syndrome.

Hoarding with and without excessive buying: results of a pilot study.

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.

Gunbuy-backprograms have been proposed as away to remove unwanted firearms from circulation, but remain controversial because their ability to prevent firearm injuries remains unproven. The purpose of this study is to describe the demographics of individuals participating in Connecticut's gun buy-backprogram in the context of annual gun sales and the epidemiology of firearm violence in the state. Over four years the buy-back program collected 464 firearms, including 232 handguns. In contrast, 91,602 firearms were sold in Connecticut during 2009 alone. The incidence of gun-related deaths was unchanged in the two years following the inception of the buy-back program. Suicide was associated with older age (mean = 51 +/- 18years) and Caucasian race (n = 539, 90%). Homicide was associated with younger age (mean = 30 +/- 12 years) and minority race (n = 425, 81%). A gun buy-back program alone is not likely to produce a measurable decrease in firearm injuries and deaths.

To determine whether parent report of difficulty buying food was associated with child body mass index (BMI) z-score or with eating habits in young children. This was a cross-sectional study in primary care offices in Toronto, Ontario. Subjects were children aged 1-5 years and their caregivers, recruited through the TARGet Kids! Research Network from July 2008 to August 2011. Regression models were developed to test the association between parent report of difficulty buying food because of cost and the following outcomes: child BMI z-score, parent's report of child's intake of fruit and vegetables, fruit juice and sweetened beverages, and fast food. Confounders included child's age, sex, birth weight, maternal BMI, education, ethnicity, immigration status, and neighbourhood income. The study sample consisted of 3333 children. Data on difficulty buying food were available for 3099 children, and 431 of these (13.9%) were from households reporting difficulty buying food. There was no association with child BMI z-score (p = 0.86). Children from households reporting difficulty buying food (compared with never having difficulty buying food) had increased odds of consuming three or fewer servings of fruits and vegetables per day (odds ratio [OR]: 1.31, 95% confidence interval [CI]: 1.03-1.69), more than one serving of fruit juice/sweetened beverage per day (OR: 1.60, 95% CI: 1.28-2.00), and, among children 1-2 years old, one or more servings of fast food per week (OR: 2.91, 95% CI: 1.67-5.08). Parental report of difficulty buying food is associated with less optimal eating habits in children but not with BMI z-score.

Infiltration of forest fire and residential wood smoke: an evaluation of air cleaner effectiveness.

2008-09-01

Communities impacted by fine-particle air pollution (particles with an aerodynamic diameter less than 2.5 microm; PM(2.5)) from forest fires and residential wood burning require effective, evidence-based exposure-reduction strategies. Public health recommendations during smoke episodes typically include advising community members to remain indoors and the use of air cleaners, yet little information is available on the effectiveness of these measures. Our study attempted to address the following objectives: to measure indoor infiltration factor (F(inf)) of PM(2.5) from forest fires/wood smoke, to determine the effectiveness of high-efficiency particulate air (HEPA) filter air cleaners in reducing indoor PM(2.5), and to analyze the home determinants of F(inf) and air cleaner effectiveness (ACE). We collected indoor/outdoor 1-min PM(2.5) averages and 48-h outdoor PM(2.5) filter samples for 21 winter and 17 summer homes impacted by wood burning and forest fire smoke, respectively, during 2004-2005. A portable HEPA filter air cleaner was operated indoors with the filter removed for one of two sampling days. Particle F(inf) and ACE were calculated for each home using a recursive model. We found mean F(inf)+/-SD was 0.27+/-0.18 and 0.61+/-0.27 in winter (n=19) and summer (n=13), respectively, for days when HEPA filters were not used. Lower F(inf)+/-SD values of 0.10+/-0.08 and 0.19+/-0.20 were found on corresponding days when HEPA filters were in place. Mean+/-SD ACE ([F(inf) without filter-F(inf) with filter]/F(inf) without filter) in winter and summer were 55+/-38% and 65+/-35%, respectively. Number of windows and season predicted F(inf) (P<0.001). No significant predictors of ACE were identified. Our findings show that remaining indoors combined with use of air cleaner can effectively reduce PM(2.5) exposure during forest fires and residential wood burning.

Control of asthma triggers in indoor air with air cleaners: a modeling analysis.

2008-08-06

Reducing exposure to environmental agents indoors shown to increase asthma symptoms or lead to asthma exacerbations is an important component of a strategy to manage asthma for individuals. Numerous investigations have demonstrated that portable air cleaning devices can reduce concentrations of asthma triggers in indoor air; however, their benefits for breathing problems have not always been reproducible. The potential exposure benefits of whole house high efficiency in-duct air cleaners for sensitive subpopulations have yet to be evaluated. We used an indoor air quality modeling system (CONTAM) developed by NIST to examine peak and time-integrated concentrations of common asthma triggers present in indoor air over a year as a function of natural ventilation, portable air cleaners, and forced air ventilation equipped with conventional and high efficiency filtration systems. Emission rates for asthma triggers were based on experimental studies published in the scientific literature. Forced air systems with high efficiency filtration were found to provide the best control of asthma triggers: 30-55% lower cat allergen levels, 90-99% lower risk of respiratory infection through the inhalation route of exposure, 90-98% lower environmental tobacco smoke (ETS) levels, and 50-75% lower fungal spore levels than the other ventilation/filtration systems considered. These results indicate that the use of high efficiency in-duct air cleaners provide an effective means of controlling allergen levels not only in a single room, like a portable air cleaner, but the whole house. These findings are useful for evaluating potential benefits of high efficiency in-duct filtration systems for controlling exposure to asthma triggers indoors and for the design of trials of environmental interventions intended to evaluate their utility in practice.

We test the exposure-persuasion-identification-commitment (EPIC) process model of buy-in, here applied to student (n = 245) engagement in an undergraduate science course featuring active learning. Student buy-in to active learning was positively associated with engagement in self-regulated learning and students' course performance. The positive associations among buy-in, self-regulated learning, and course performance suggest buy-in as a potentially important factor leading to student engagement and other student outcomes. These findings are particularly salient in course contexts featuring active learning, which encourage active student participation in the learning process. © 2016 A. J. Cavanagh et al.

Sharia compliant wheelchair wheel cleaner was developed in order to assist the muslim Person with Disabilities (PWD) to pray in the mosque without leaving their wheelchair because of the filthy wheels. Though there are many wheelchair wheel cleaning system in the market, it is very rare to find sharia compliant cleaning system that applies sertu concept which is one of the cleaning and purification technique in Islamic practice. The sertu concept is based on 6:1 ratio that refers to the six times pipe water cleaning and one time soiled water cleaning. The development process consists of design stage, fabrication and system installation stage and followed by testing stage. During the design stage, the proposed prototype underwent design brainstorming, operation programming and structural simulation analysis. Once fabricated, the cleaner prototype underwent was tested. The results showed that the prototype can cater load up to 100kg with 1.31×10-6 mm shaft bending displacement. The water ejection timing varied approximately 3% compared to the program.

The objective of this study was to investigate the frequency of compulsive buying in bipolar disorder (BD), to compare it with healthy controls, and to search if there is a difference between bipolar cases with and without compulsive buying in terms of sociodemographic qualities, temperament, clinical characteristics and comorbid diagnoses. One-hundred outpatient cases diagnosed as BD according to DSM-IV were evaluated consecutively. Following the diagnosis interview (SCID-I and II) the subjects completed the mood disorders registry form, Compulsive Buying Scale and TEMPS-A. Compulsive buying scores were higher in bipolar patients than healthy controls (p<0.001). Cases with compulsive buying revealed higher cyclothymic and irritable temperament scores than other bipolar patients (p=0.029 vs 0.045). Premenstrual syndrome and postpartum onset were more frequent, while psychotic symptoms were less in compulsive buyer bipolar patients (p=0.002, 0.009 vs 0.034). Severity of episode was lower (p=0.01), number of episodes was higher (p=0.009). Acute onset and remission before and after maintenance treatment were more frequent in patients with compulsive buying (p=0.011 and p=0.011). Full remission between episodes was 100%. Cases with axis-1 and axis-2 comorbidities demonstrated higher compulsive buying scores (p=0.025 and 0.005). Treatment regimen differences between patients are a limitation of the study. This is the first study to relate compulsive buying with the clinical characteristics of BD. Our results reveal that compulsive buying in BD occurs together with mood episodes which are not very severe, but frequent and with abrupt onset. Copyright © 2011 Elsevier B.V. All rights reserved.

As part of a solvent substitution program, an evaluation of selected alternative cleaners for solder flux and mold release removal has been performed. Six cleaners were evaluated for their efficiency in removing a rosin mildly activated flux and a silicone mold release from copper, 17-4PH stainless steel, polyimide quartz glass and tin-lead surfaces. A parallel effort also studied deionized water removal of organic acid fluxes. Auger electron spectroscopy and X-ray photoelectron spectroscopy were used to determine relative elemental cleanliness of the outermost atomic layers. An Omega Meter Test was used to measure residual ionic contamination. Water drop contact angles weremore » used to measure the effectiveness of silicone removal from Cu substrates. In most cases, the cleanliness levels were good to excellent. 10 refs., 8 figs., 19 tabs.« less

Use of GC/MS and Microtome Techniques as Methods to Evaluate ODC Free Cleaner Diffusion and Evaporation in Insulation and Phenolic Case Material

Biegert, L. L.

2001-01-01

Because of the 1990 Clean Air Act Amendment (CAAA) many chlorinated solvents used in the aerospace industry are being phased out. Replacement of the ODC (ozone-depleting chemicals) with less volatile, non-ozone depleting cleaners has been extensively studied over the past seven years at Thiokol Propulsion, a Division of Cordant Technologies, Inc. The down selection of ODC replacement cleaners has been based on several factors including the diffusion evaporation of the cleaners in selected substrates. Methodologies were developed to evaluate the cleaner content in substrates. Methods of cutting thin slices of material (microtoming) were combined with GC/MS (gas chromatography/mass spectroscopy) analysis. Substrates evaluated in this study include potential solid rocket motor materials: ASNBR (asbestos-filled nitrile butadiene rubber) and CFEPDM (carbon-filled ethylene propylene dimonomer) insulation and glass (GCP), carbon (CCP) and silica (SCP) cloth phenolic substrates with fibers either parallel (0 deg) or perpendicular (90 deg) to the surface. Residue profiles indicate both cleaner and substrate composition affect the diffusion and subsequent evaporation of the cleaner from the substrate surface.

Compulsive buying is particularly relevant in nations with high levels of consumer spending. Most previous studies have focused on European and North America populations. This study explores compulsive buying amongst citizens of the United Arab Emirates, an Arab nation with high retail outlet density, and high levels of consumer spending. Female college students (N=100) completed an English/Arabic version of the compulsive buying scale along with a measure of depression. Rates of compulsive buying were higher than those reported in any previously published study. Furthermore, in line with previous findings from other nations, compulsive buying was associated with elevated depressive symptomatology. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Consumer motivations toward buying local rice: The case of northern Iranian consumers.

Rahnama, Hassan

2017-07-01

This research had two purposes. The first aim was to identify Iranian and Non-Iranian rice consumers based on demographic characteristics and examine difference of these features with buying behaviors. The second purpose of study was to investigate consumer's motivation to buy local rice in Iran. The sample were 1500 people (men and women). The data was collected by using questionnaire based on a face-to-face survey. Chi-square, confirmatory factor analysis, and multiple linear regression were applied to assess collected data by a questionnaire survey. Regarding Iranian local rice buyers, 884 people buy local rice. Chi-square test showed that there is a significant difference between gender, having children, and marital status in buying local rice. Habitual Iranian local rice buyers include: female (51%), people who are more than 45 years old (51%), people with children (63%), people who are living urban (61%), married people (48%) and individuals that their monthly income is between 321.5 and 625 Dollars (53%). Regarding non-Iranian rice buyers, 616 people buy it. Also there is a significant difference between gender, location, marital status, and income in buying local rice. For considering consumers motivation toward buying local rice the econometrical model is used. Model had three aspects including; quality aspects (taste, good appearance), economic aspects (price, convenience, consumer's ethnocentrism), and safety aspects (health, not using pesticides and environment protection) and seven subset. The results of analysis indicated that quality aspects, economic aspects and safety aspects have positive effects on buying Iranian local rice. Also, indicative variables including; taste, good appearance, price, convenience, consumer's ethnocentrism, health, not using pesticides and environment have significant effects on buying it.

The textile industry has a high environmental impact so that implementing cleaner production audit is an effective way to achieve energy conservation and emissions reduction. But the evaluation method in current cleaner production audit divided the evaluation of CPOs into two parts: environment and economy. The evaluation index system was constructed from three criteria of environment benefits, economy benefits and product performance; weights of five indicators were determined by combination weights of entropy method and factor weight sorting method. Then efficiencies were evaluated comprehensively. The results showed that the best alkali recovery option was the nanofiltration membrane method (S=0.80).

Control of asthma triggers in indoor air with air cleaners: a modeling analysis

PubMed Central

Myatt, Theodore A; Minegishi, Taeko; Allen, Joseph G; MacIntosh, David L

2008-01-01

Background Reducing exposure to environmental agents indoors shown to increase asthma symptoms or lead to asthma exacerbations is an important component of a strategy to manage asthma for individuals. Numerous investigations have demonstrated that portable air cleaning devices can reduce concentrations of asthma triggers in indoor air; however, their benefits for breathing problems have not always been reproducible. The potential exposure benefits of whole house high efficiency in-duct air cleaners for sensitive subpopulations have yet to be evaluated. Methods We used an indoor air quality modeling system (CONTAM) developed by NIST to examine peak and time-integrated concentrations of common asthma triggers present in indoor air over a year as a function of natural ventilation, portable air cleaners, and forced air ventilation equipped with conventional and high efficiency filtration systems. Emission rates for asthma triggers were based on experimental studies published in the scientific literature. Results Forced air systems with high efficiency filtration were found to provide the best control of asthma triggers: 30–55% lower cat allergen levels, 90–99% lower risk of respiratory infection through the inhalation route of exposure, 90–98% lower environmental tobacco smoke (ETS) levels, and 50–75% lower fungal spore levels than the other ventilation/filtration systems considered. These results indicate that the use of high efficiency in-duct air cleaners provide an effective means of controlling allergen levels not only in a single room, like a portable air cleaner, but the whole house. Conclusion These findings are useful for evaluating potential benefits of high efficiency in-duct filtration systems for controlling exposure to asthma triggers indoors and for the design of trials of environmental interventions intended to evaluate their utility in practice.

[Pathological buying. A review of the current knowledge regarding this condition of behavioral excess].

PubMed

Müller, A; de Zwaan, M

2010-04-01

Compulsive buying is characterized by frequent excessive purchasing of items that are primarily not needed or used. The compulsive buying behavior results in mental, social, financial and often legal problems. Although compulsive buying affects a significant percentage of the general population and has received increasing attention in research, it has largely been ignored in clinical practice. Compulsive buying disorder is currently conceptualized as an"impulse control disorder not otherwise specified". However, the appropriate classification continues to be debated. Compulsive buying is associated with significant psychiatric co-morbidity, especially with depressive, anxiety, obsessive-compulsive, substance use, personality, and other impulse control disorders. Small controlled trials failed to confirm the efficacy of antidepressants in the treatment of compulsive buying disorder, whereas early evidence suggests that cognitive behavioral therapy is helpful in alleviating compulsive buying symptoms. Further research is needed to establish a better understanding of etiology, classification, and treatment strategies.

The project ìconsumer perception and buying behavior (the pasta studyî) is basically measures the development of perception through different variables and identify those factors which stimulate buying decision of consumer. Among various variables which effect consumer buying pattern I choose AWARENESS and AVAILABILITY of the product as two main variables which have strong effect on popularity and sale of pasta product. As my research is totally based on qualitative method thatís why I choose quota sampling technique and collect data by interviewing house wives resides in different areas of Karachi. The reason of choosing only house wives as respondent is that house wives can give true insight factors which hinder the popularity of pasta products in Pakistan. Focus group discussions have been conducted to extract findings. 30 house wives have been interviewed and their responses have been analyzed.

Patterns of resource-use and competition for mutualistic partners between two species of obligate cleaner fish

NASA Astrophysics Data System (ADS)

Adam, T. C.; Horii, S. S.

2012-12-01

Cleaner mutualisms on coral reefs, where specialized fish remove parasites from many species of client fishes, have greatly increased our understanding of mutualism, yet we know little about important interspecific interactions between cleaners. Here, we explore the potential for competition between the cleaners Labroides dimidiatus and Labroides bicolor during two distinct life stages. Previous work has demonstrated that in contrast to L. dimidiatus, which establish cleaning stations, adult L. bicolor rove over large areas, searching for clients. We show that site-attached juvenile L. bicolor associate with different microhabitat than juvenile L. dimidiatus and that L. bicolor specialize on a narrower range of species than L. dimidiatus as both juveniles and adults. Further, we present evidence suggesting that differences in resource-use are influenced by competitive interactions between the two species. Finally, we discuss the implications of these results for understanding the ecology and evolution of the mutualism.

Estimated prevalence of compulsive buying behavior in the United States.

PubMed

Koran, Lorrin M; Faber, Ronald J; Aboujaoude, Elias; Large, Michael D; Serpe, Richard T

2006-10-01

Compulsive buying (uncontrolled urges to buy, with resulting significant adverse consequences) has been estimated to affect from 1.8% to 16% of the adult U.S. population. To the authors' knowledge, no study has used a large general population sample to estimate its prevalence. The authors conducted a random sample, national household telephone survey in the spring and summer of 2004 and interviewed 2,513 adults. The interviews addressed buying attitudes and behaviors, their consequences, and the respondents' financial and demographic data. The authors used a clinically validated screening instrument, the Compulsive Buying Scale, to classify respondents as either compulsive buyers or not. The rate of response was 56.3%, which compares favorably with rates in federal national health surveys. The cooperation rate was 97.6%. Respondents included a higher percentage of women and people ages 55 and older than the U.S. adult population. The estimated point prevalence of compulsive buying among respondents was 5.8% (by gender: 6.0% for women, 5.5% for men). The gender-adjusted prevalence rate was 5.8%. Compared with other respondents, compulsive buyers were younger, and a greater proportion reported incomes under 50,000 US dollars. They exhibited more maladaptive responses on most consumer behavior measures and were more than four times less likely to pay off credit card balances in full. A study using clinically valid interviews is needed to evaluate these results. The emotional and functional toll of compulsive buying and the frequency of comorbid psychiatric disorders suggests that studies of treatments and social interventions are warranted.

The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC. As part of the development of vacuum education, the society arranges the participation of

The measuring time and measuring intervals to evaluate different type of air cleaner performance to remove formaldehyde were provided. The natural decay measurement and formaldehyde removal measurement were conducted in 1.5 m3 and 30 m3 test chamber. The natural decay rate was determined by acquiring formaldehyde concentration data at 15 minute intervals for 2.5 hours. The measured decay rate was determined by acquiring formaldehyde concentration data at 5 minute intervals for 1.2 hours. When the wind power of air cleaner is smaller than 30 m3/h or measuring performance of no wind power air clearing product, the 1.5 m3 test chamber can be used. Both the natural decay rate and the measured decay rate are determined by acquiring formaldehyde concentration data at 8 minute intervals for 64 minutes. There were different measuring time and measuring intervals to evaluate different type of air cleaner performance to remove formaldehyde.

Compulsive buying has been generally ignored in the psychiatric literature, although it is apparently frequent, underrecognized, and can lead to severe financial and legal consequences for its sufferers. The current investigation was designed to assess the overall life-style and problems of subjects identified as compulsive shoppers. Forty-six compulsive buyers were assessed for comorbid psychiatric disorders with the Diagnostic Interview Schedule, the Structured Interview for DSM-III-R Personality Disorders, and a semistructured interview to assess buying behavior. The typical shopper was a 31-year-old female who had developed compulsive buying at age 18 years. Subjects spent their money on clothing, shoes, and records/compact discs. The average debt load accrued was $5,422 out of an average yearly income of $23,443. More than two-thirds met lifetime criteria for a major (Axis I) mental disorder, most commonly anxiety, substance abuse, and mood disorders. Nearly 60% were found to meet criteria for a DSM-III-R personality disorder, most commonly the obsessive-compulsive, borderline, and avoidant types. The authors conclude that compulsive buying is a definable clinical syndrome which can cause its sufferers significant distress and is associated with significant psychiatric comorbidity.

The survey was part of an industrywide mortality and industrial hygiene study of dry cleaning workers exposure to perchlorethylene. To gather data for this larger study, an on site visit was made to the Carman's Classic Cleaners located in Richmond, California. Carman's Classic Cleaners has been using PCE since the present owner had the building constructed in 1954. About 621 kilograms of clothing were dry cleaned each week, with about 129 liters of PCE consumed monthly. The workforce of six includes two pressers, a full time employee who works at the counter and also sews, a part time maintenance man,more » the owner, and his wife. The owner did all the dry cleaning and spotting while his wife marked clothing and worked the counter. Air samples were collected using battery operated pumps and charcoal tubes. The time weighted average exposure to PCE during the 5 hours of operation was 25 parts per million (ppm) for the dry cleaner and 2ppm for the presser. Samples collected in the vicinity of the front counter, washer, and spotting table indicated PCE levels of 3, 29, and 21ppm, respectively. Five minute peak samples during clothing transfer indicated PCE levels of 22, 38, and 17ppm. These exposures were well within the current standards. However, as PCE is a suspected carcinogen, it is necessary that levels be lowered as much as possible. The author recommends measures to help bring this about.« less

Evolutionary game analysis and regulatory strategies for online group-buying based on system dynamics

The emergence of online group-buying provides a new consumption pattern for consumers in e-commerce era. However, many consumers realize that their own interests sometimes can't be guaranteed in the group-buying market due to the lack of being regulated. This paper aims to develop effective regulation strategies for online group-buying market. To the best of our knowledge, most existing studies assume that three parties in online group-buying market, i.e. the retailer, the group-buying platform and the consumer, are perfectly rational. To better understand the decision process, in this paper, we incorporate the concept of bounded rationality into consideration. Firstly, a three-parties evolutionary game model is established to study each player's game strategy based on bounded rationality. Secondly, the game model is simulated as a whole by adopting system dynamics to analyze its stability. Finally, theoretical analysis and extensive computational experiments are conducted to obtain the managerial insights and regulation strategies for online group-buying market. Our results clearly demonstrate that a suitable bonus-penalty measure can promote the healthy development of online group-buying market.

Partitioning of residual D-limonene cleaner vapor among organic materials in weapons

1993-03-01

D-limonene is a replacement solvent selected by Sandia and Allied-Signal to clean solder flux from electronics assemblies in firesets and programmers. D-limonene is much slower drying than the solvents it has replaced and this has raised concerns that residual quantities of the cleaner could be trapped in the electronics assemblies and eventually carried into warhead assemblies. This paper describes a study designed to evaluate how vapors from residual d-limonene cleaner would be partitioned among typical organic materials in a Livermore device. The goal was to identify possible compatibility problems arising from the use of d-limonene and, in particular, any interactionsmore » it may have with energetic materials. To predict the partitioning behavior of d-limonene, a simple model was developed and its predictions are compared to the experimental findings.« less

Effects of mood induction on consumers with vs. without compulsive buying propensity: an experimental study.

PubMed

Vogt, Sinje; Hunger, Antje; Türpe, Tina; Pietrowsky, Reinhard; Gerlach, Alexander L

2014-12-15

Compulsive buying (CB) is excessive and leads to impairment and distress. Several studies aimed to explore the phenomenology and antecedents of CB, especially affective states. However, these studies mostly used retrospective self-report and mostly focused on compulsive buyers only. Therefore, this study aims to directly compare consumers with CB propensity and controls on experimental proxies of buying behavior and to investigate 1) effects of neutral vs. negative mood inductions and 2) whether mood effects on buying behavior are specific to CB. Forty female consumers with CB propensity and 40 female controls were randomly assigned to a neutral or negative mood induction. Buying related behavior (likelihood to expose oneself to a shopping situation, urge and probability to buy, willingness to pay) was assessed. Consumers with CB propensity differed from controls in all buying behavior aspects except for willingness to pay. Neither main effects of mood nor group×mood interaction effects on buying behavior were found. However, consumers with CB propensity were emotionally more strongly affected by a negative mood induction. Although negative affect has previously been reported to precede buying episodes in CB, our findings do not indicate specific negative mood effects on buying, neither in CB nor in controls.

Maraz, Aniko; van den Brink, Wim; Demetrovics, Zsolt

2015-08-30

Compulsive buying is a relatively new psychopathological concept and very few data are currently available regarding the prevalence and validity of compulsive buying disorder. In this cross-sectional study, we establish the prevalence of compulsive buying disorder in shopping mall visitors and explore the construct validity of the concept using the revised version of the Edwards Compulsive Buying Scale in 1441 shopping mall visitors looking at shopping habits, current substance use (smoking, alcohol and illicit drug) and various psychological characteristics. Overall, 8.7% (95% CI: 7.3-10.3) of our sample was classified as having a compulsive buying disorder. Compulsive buyers were younger, less educated and more likely to be female than non-compulsive buyers. They were also more likely to have used licit and illicit substances. Compulsive buyers also reported higher levels of impulsivity and obsessive-compulsive symptoms, lower levels of well-being and self-esteem and more psychological distress. Finally, compulsive buyers were five times more likely to meet criteria for borderline personality disorder than non-compulsive buyers. Compulsive buying is a frequent disorder in shopping mall visitors and is associated with important and robust indicators of psychopathology thus supporting the validity of the construct.

You save money when you buy in bulk: does volume-based pricing cause people to buy more beer?

PubMed

Bray, Jeremy W; Loomis, Brett R; Engelen, Mark

2009-05-01

This paper uses supermarket scanner data to estimate brand- and packaging-specific own- and cross-price elasticities for beer. We find that brand- and packaging-specific beer sales are highly price elastic. Cross-price elasticity estimates suggest that individuals are more likely to buy a higher-volume package of the same brand of beer than they are to switch brands. Policy simulations suggest that regulation of volume-based price discounts is potentially more effective than a tax increase at reducing beer consumption. Our results suggest that volume-based price discounting induces people to buy larger-volume packages of beer and may lead to an increased overall beer consumption. (c) 2008 John Wiley & Sons, Ltd.

Trotzke, Patrick; Starcke, Katrin; Müller, Astrid; Brand, Matthias

2015-01-01

The study aimed to investigate different factors of vulnerability for pathological buying in the online context and to determine whether online pathological buying has parallels to a specific Internet addiction. According to a model of specific Internet addiction by Brand and colleagues, potential vulnerability factors may consist of a predisposing excitability from shopping and as mediating variable, specific Internet use expectancies. Additionally, in line with models on addiction behavior, cue-induced craving should also constitute an important factor for online pathological buying. The theoretical model was tested in this study by investigating 240 female participants with a cue-reactivity paradigm, which was composed of online shopping pictures, to assess excitability from shopping. Craving (before and after the cue-reactivity paradigm) and online shopping expectancies were measured. The tendency for pathological buying and online pathological buying were screened with the Compulsive Buying Scale (CBS) and the Short Internet Addiction Test modified for shopping (s-IATshopping). The results demonstrated that the relationship between individual’s excitability from shopping and online pathological buying tendency was partially mediated by specific Internet use expectancies for online shopping (model’s R² = .742, p < .001). Furthermore, craving and online pathological buying tendencies were correlated (r = .556, p < .001), and an increase in craving after the cue presentation was observed solely in individuals scoring high for online pathological buying (t(28) = 2.98, p < .01, d = 0.44). Both screening instruments were correlated (r = .517, p < .001), and diagnostic concordances as well as divergences were indicated by applying the proposed cut-off criteria. In line with the model for specific Internet addiction, the study identified potential vulnerability factors for online pathological buying and suggests potential parallels.

Trotzke, Patrick; Mitchell, James E.; de Zwaan, Martina

2015-01-01

The study was designed to develop a new screening instrument for pathological buying (PB), and to examine its psychometric properties in a large-scale sample. By using a facet theoretical approach and based on literature as well as on clinical experience, a 20-item Pathological Buying Screener (PBS) was developed and administered to a representative German sample (n = 2,539). Valid data were available from 2,403 participants who were subjects for three subsequent empirical studies. The first study explored the factor structure using exploratory factor analyses in a subsample of 498 participants. Based on factor loadings, a 13-item version with the two factors loss of control / consequences and excessive buying behavior was revealed. This two-factor model was confirmed in study 2 by confirmatory factor analysis performed on another subsample (n = 1,905). Study 3 investigated age and gender effects and convergent validity of the PBS using the Compulsive Buying Scale (CBS) in the full sample (N = 2,403). The total PBS score was adequately correlated with the CBS score. Hierarchical regression analyses with the CBS score as the dependent variable and the two PBS factors as the predictors indicated an own incremental validity of the two factors in participants ≤ 65 years. The reliability of the total score as well as of the two subscales was good to excellent. Overall, the PBS represents a useful measure for PB. Future studies are needed to replicate the two-factor structure in clinical samples and to define a valid cutoff for PB. PMID:26488872

To evaluate the associations between refraining from buying prescribed medications and selected factors among older persons. A total of 4467 people aged 60-84 years from seven European countries answered a questionnaire (response rate 45.2%). Refraining from buying prescribed medications was measured with the question: 'Have you ever refrained from buying prescribed medication and care?' About 11.9% of older people refrained from buying prescribed medications. The multiple regression analysis showed that ages 60-64 (odds ratio (OR) = 2.08; 95% confidence interval (95%CI): 1.38-3.13) and 65-69 (OR = 1.73; 95%CI: 1.16-2.57) years, experience of financial strain (OR = 1.59; 95%CI: 1.27-2.01), as well as exposure to abuse (OR = 1.64; 95%CI: 1.31-2.06) when taking into account country of participant were independently associated with refraining from buying medications, while an opposite association was observed for being male (OR = 0.72; 95%CI: 0.58-0.91). The study found that refraining from buying prescription medications is a problem among older people and identified a number of factors associated with this. © 2013 ACOTA.

Large Cleaner Detectors for the UCN τ Neutron Lifetime Experiment

NASA Astrophysics Data System (ADS)

Gonzalez, Francisco; UCNtau Collaboration

2017-09-01

The UCN τ experiment at Los Alamos National Laboratory measures the neutron β-decay lifetime by storing ultracold neutrons (UCNs) in a magneto-gravitational trap for holding times longer than the neutron's lifetime. Neutrons with energies above the trapping potential can escape the trap, giving rise to a systematic error. To mitigate this effect, a large polyethylene sheet is lowered into the trap to remove the high energy unbound neutrons. High energy UCN upscatter in the polyethylene sheet and leave the trap. Such a ``UCN spectrum cleaner,'' covering half the trap top, was shown to be effective in removing high-energy neutrons in previous run cycles. During this run cycle, the UCN τ collaboration has added two thermal neutron detectors on the spectrum cleaner. The new thermal neutron detectors will monitor high-energy neutrons throughout upcoming run cycles, providing important information on the neutron normalization, spectral cleaning, and heating during storage. These detectors use LiF-ZnS sheets coupled to a wavelength-shifting plastic slab, with silicon photomultipliers attached to the edges. We will present results of the light detection simulation and performance tests of these detectors.

Compulsive buying and hoarding as identity substitutes: The role of materialistic value endorsement and depression.

PubMed

Claes, Laurence; Müller, Astrid; Luyckx, Koen

2016-07-01

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.

Vacuum mechatronics

NASA Technical Reports Server (NTRS)

Hackwood, Susan; Belinski, Steven E.; Beni, Gerardo

1989-01-01

The discipline of vacuum mechatronics is defined as the design and development of vacuum-compatible computer-controlled mechanisms for manipulating, sensing and testing in a vacuum environment. The importance of vacuum mechatronics is growing with an increased application of vacuum in space studies and in manufacturing for material processing, medicine, microelectronics, emission studies, lyophylisation, freeze drying and packaging. The quickly developing field of vacuum mechatronics will also be the driving force for the realization of an advanced era of totally enclosed clean manufacturing cells. High technology manufacturing has increasingly demanding requirements for precision manipulation, in situ process monitoring and contamination-free environments. To remove the contamination problems associated with human workers, the tendency in many manufacturing processes is to move towards total automation. This will become a requirement in the near future for e.g., microelectronics manufacturing. Automation in ultra-clean manufacturing environments is evolving into the concept of self-contained and fully enclosed manufacturing. A Self Contained Automated Robotic Factory (SCARF) is being developed as a flexible research facility for totally enclosed manufacturing. The construction and successful operation of a SCARF will provide a novel, flexible, self-contained, clean, vacuum manufacturing environment. SCARF also requires very high reliability and intelligent control. The trends in vacuum mechatronics and some of the key research issues are reviewed.

The Role of Self-esteem and Fear of Negative Evaluation in Compulsive Buying

PubMed Central

Biolcati, Roberta

2017-01-01

Compulsive buying is a relatively new addictive disorder that interferes with everyday functioning and may result in serious psychological and financial problems (1). A very few data are currently available regarding this behavioral addiction. This study investigated gender differences in the relationships between contingent self-esteem (CSE), fear of negative evaluation (FNE), and compulsive buying. Participants included 240 Italian adults (170 females, M age = 33.80) who responded to self-report questionnaires. The results showed that women scored higher on CSE and FNE scales than men. No gender differences were found in compulsive buying tendencies. CSE and FNE were positively related to CB. Furthermore, structural equation modeling confirmed the evidence on CSE as a strong predictor of CB for both genders. Interestingly, FNE seems to play a mediating role between CSE and compulsive buying behaviors only for women. These findings highlight the importance of studying self-esteem in compulsive buying tendencies to inquire more deeply into the underlying mechanisms of some compulsive behaviors. PMID:28512435

Prevalence study of compulsive buying in a sample with low individual monthly income.

PubMed

Leite, Priscilla Lourenço; Silva, Adriana Cardoso

2015-01-01

Compulsive buying can be characterized as an almost irresistible impulse to acquire various items. This is a current issue and the prevalence rate in the global population is around 5 to 8%. Some surveys indicate that the problem is growing in young and low-income populations. To evaluate the prevalence of compulsive buying among people with low personal monthly incomes and analyze relationships with socio-demographic data. The Compulsive Buying Scale was administered to screen for compulsive buying and the Hospital Anxiety and Depression Scale was used to assess anxiety and depression in a sample of 56 participants. Pearson coefficients were used to test for correlations. The results indicated that 44.6% presented an average family income equal to or greater than 2.76 minimum wages. It is possible that compulsive buying is not linked to the purchasing power since it was found in a low-income population. Despite the small sample, the results of this study are important for understanding the problem in question.

Materialism and addictive buying in women: the mediating role of anxiety and depression.

Otero-López, José Manuel; Villardefrancos, Estíbaliz

2013-08-01

There is empirical evidence regarding the interrelationships between materialism, negative emotions, and addictive buying. The aim of this study was to clarify the direction of the relationships among these variables. Specifically, the main objective was to explore the possible mediating roles of anxiety and depression in the link between materialism and addictive buying. Path analysis results, using a sample of 685 women, generally supported the suitability of the proposed model in which anxiety and depression mediated the effects of the materialism dimensions, "importance" and "success," on addictive buying, and that depression also mediates the influence of the "importance" and "happiness" dimensions. Moreover, a direct effect of the importance dimension on addictive buying was found.

Risk assessment of amorphous silicon dioxide nanoparticles in a glass cleaner formulation

Scheel, Julia; Karsten, Stefan; Stelter, Norbert; Wind, Thorsten

2013-01-01

Since nanomaterials are a heterogeneous group of substances used in various applications, risk assessment needs to be done on a case-by-case basis. Here the authors assess the risk (hazard and exposure) of a glass cleaner with synthetic amorphous silicon dioxide (SAS) nanoparticles during production and consumer use (spray application). As the colloidal material used is similar to previously investigated SAS, the hazard profile was considered to be comparable. Overall, SAS has a low toxicity. Worker exposure was analysed to be well controlled. The particle size distribution indicated that the aerosol droplets were in a size range not expected to reach the alveoli. Predictive modelling was used to approximate external exposure concentrations. Consumer and environmental exposure were estimated conservatively and were not of concern. It was concluded based on the available weight-of-evidence that the production and application of the glass cleaner is safe for humans and the environment under intended use conditions.

2016-04-01

At present, no treatment recommendations can be made for compulsive buying disorder. Recent studies have found evidence for the efficacy of psychotherapeutic options, but less is known regarding the best pharmacologic treatment. The purpose of this review is to present and analyze the available published evidence on the pharmacological treatment of compulsive buying disorder. To achieve this, we conducted a review of studies focusing on the pharmacological treatment of compulsive buying by searching the PubMed/MEDLINE database. Selection criteria were applied, and 21 studies were identified. Pharmacological classes reported included antidepressants, mood stabilizers, opioid antagonists, second-generation antipsychotics, and N-methyl-D-aspartate receptor antagonists. We found only placebo-controlled trials for fluvoxamine; none showed effectiveness against placebo. Three open-label trials reported clinical improvement with citalopram; one was followed by a double-blind discontinuation. Escitalopram was effective in an open-label trial but did not show efficacy in the double-blind phase. Memantine was identified as effective in a pilot open-label study. Fluoxetine, bupropion, nortriptyline, clomipramine, topiramate and naltrexone were only reported to be effective in clinical cases. According to the available literature, there is no evidence to propose a specific pharmacologic agent for compulsive buying disorder. Future research is required for a better understanding of both pathogenesis and treatment of this disorder.

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

NASA Astrophysics Data System (ADS)

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

2014-09-01

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

The effectiveness of an air cleaner in controlling droplet/aerosol particle dispersion emitted from a patient's mouth in the indoor environment of dental clinics.

Dental healthcare workers (DHCWs) are at high risk of occupational exposure to droplets and aerosol particles emitted from patients' mouths during treatment. We evaluated the effectiveness of an air cleaner in reducing droplet and aerosol contamination by positioning the device in four different locations in an actual dental clinic. We applied computational fluid dynamics (CFD) methods to solve the governing equations of airflow, energy and dispersion of different-sized airborne droplets/aerosol particles. In a dental clinic, we measured the supply air velocity and temperature of the ventilation system, the airflow rate and the particle removal efficiency of the air cleaner to determine the boundary conditions for the CFD simulations. Our results indicate that use of an air cleaner in a dental clinic may be an effective method for reducing DHCWs' exposure to airborne droplets and aerosol particles. Further, we found that the probability of droplet/aerosol particle removal and the direction of airflow from the cleaner are both important control measures for droplet and aerosol contamination in a dental clinic. Thus, the distance between the air cleaner and droplet/aerosol particle source as well as the relative location of the air cleaner to both the source and the DHCW are important considerations for reducing DHCWs' exposure to droplets/aerosol particles emitted from the patient's mouth during treatments.

An improved adsorption vacuum trap for use in vacuum systems was designed. The distinguishing feature is the placement of a plurality of torsionally deformed metallic fins within a vacuum jacket extending from the walls to the central axis so that substantially all gas molecules pass through the jacket will impinge upon the fin surfaces. T fins are heated by direct metallic conduction, thereby ol taining a uniform temperature at the adeorbing surfaces so that essentially all of the condensible impurities from the evacuating gas are removed from the vacuum system.

Background and aims The addictive nature of compulsive buying implies that mood disturbances, stress, and cognitive biases that underlie compulsive buying might operate in ways similar in both genders. In the current study, we aimed to test hypothetical pathways of mood compensation and irrational cognitions, which may explain compulsive buying tendencies. We also examined potential gender differences in these pathways. Methods Two-hundred and thirty-two male (age: M = 20.30, SD = 1.74) and 373 female Chinese college students (age: M = 19.97, SD = 1.74) in Hong Kong and Macau completed measures assessing compulsive buying, psychological distress, avoidance coping, materialism, and buying-related cognitions. Mediation analyses via a structural equation modeling approach explained by Cheung (2007, 2009) were conducted, with gender as a grouping variable. Results There was a gender difference in the mood compensation pathway; avoidance coping partially mediated the link between psychological distress and compulsive buying severity in females only. On the other hand, the irrational cognitive pathway, in which irrational buying-related cognitions fully mediated the link between materialism and compulsive buying severity, was supported for both genders. There was no gender difference in the extent of mediation within the irrational cognitive pathway, and the mediation effect within the irrational cognitive pathway was larger than that within the mood compensation pathway for both genders. Conclusions Mood compensation processes in compulsive buying might be female specific, and secondary to irrational cognitions, which were gender invariant. Gender-dependent mechanisms and irrational cognitions should be emphasized in compulsive buying treatment.

The effects of crude oil and the effectiveness of cleaner application following oiling on US Gulf of Mexico coastal marsh plants.

2001-01-01

Field studies were conducted in two different marsh habitats in Louisiana coastal wetlands to evaluate the effects of oiling (using South Louisiana Crude oil, SLC) and the effectiveness of a shoreline cleaner (COREXIT 9580) in removing oil from plant canopies. The study sites represented two major marsh habitats; the brackish marsh site was covered by Spartina patens and the freshwater marsh was covered by Sagittaria lancifolia. Field studies were conducted in each habitat using replicated 5.8 m2 plots that were subjected to three treatments; oiled only, oiled + cleaner (cleaner was used 2 days after oiling), and a control. Plant gas exchange responses, survival, growth, and biomass accumulation were measured. Results indicated that oiling led to rapid reductions in leaf gas exchange rates in both species. However, both species in 'oiled + cleaned' plots displayed improved leaf conductance and CO2 fixation rates. Twelve weeks after treatment initiation, photosynthetic carbon fixation in both species had recovered to normal levels. Over the short-term, S. patens showed more sensitivity to oiling with SLC than S. lancifolia as was evident from the data of the number of live shoots and above-ground biomass. Above-ground biomass remained significantly lower than control in S. patens under 'oiled' and 'oiled + cleaned' treatments while it was comparable to controls in S. lancifolia. These studies indicated that the cleaner removed oil from marsh grasses and alleviated the short-term impact of oil on gas exchange function of the study plants. However, use of cleaner had no detectable effects on above-ground biomass production or regeneration at the end of the first growing season in S. patens. Similarly, no beneficial effects of cleaner on carbon fixation and number of live shoots were apparent beyond 12 weeks in S. lancifolia.

1997-04-01

The authors report the results of an open trial of fluvoxamine in the treatment of compulsive buying. Ten nondepressed subjects were recruited through word-of-mouth and rnet restrictive inclusion/exclusion criteria. Subjects were assessed with the Yale-Brown Obsessive-Compulsive Scale modified for compulsive buying, the Clinical Global Impression scale, and other measures. After a single-blind 1-week placebo run-in, subjects received fluvoxamine up to 300 mg daily for 9 weeks. Nine of 10 subjects improved and were less preoccupied with shopping, spent less time shopping, and reported spending less money. We conclude that compulsive buyers can be recruited for research and their symptoms measured and monitored and, finally, that fluvoxamine may be effective in its treatment.

Cleaner Technology in the Hard Disk Drive Manufacturing Industry: A Case Study

Moolla, Premchai; Chompu-inwai, Rungchat

2010-10-01

The objectives of this research are to improve raw material and energy consumption efficiency, as well as reduce defects and the use of chemicals in the arm coil assembly process of hard disk drive manufacturing in the case study company by applying the Cleaner Technology concepts. The four main sequential steps used in this research were: (1) pre-assessment, (2) assessment, (3) feasibility study, and (4) implementation. In the first step, raw data, such as process flows, raw material usage and defects data were collected. In the second step, the loss during production and causes of loss were analyzed. Opportunities to reduce raw material, chemical and energy wastage could then be recommended. The next step was to evaluate the feasibility and potential benefits of a particular Cleaner Technology opportunity. Finally, in the last step, after a thorough evaluation and implementation of the opportunities to apply Cleaner Technology, the results showed that arm coil defects could be reduced by improving the production process using the ECRS technique. ECRS stands for Eliminate, Combine, Rearrange and Simplify. This improvement reduced arm coil defect rates from 0.48% to 0.15%, thus saving approximately 139,638 Thai Baht per month. In addition, production stoppage decision made by workers was used to increase employee involvement in defect detection. Allowing workers to participate in such a decision was an effective way to reduce defect rate and could motivate workers to produce a better quality job. This resulted in arm coil defects reducing from 0.41% to 0.025%, with about 74,562 Thai Baht per month saving. Additionally, an increase in the efficiency of electricity consumption occurred, by increasing the speed of the infrared oven conveyor belt, improving average productivity from 533 pieces/hour to 560 pieces/hour, without adversely affecting product costs and quality, thus producing products of up to the value of 206,242 Thai Baht per month. Furthermore, the new

Fish mucus versus parasitic gnathiid isopods as sources of energy and sunscreens for a cleaner fish

NASA Astrophysics Data System (ADS)

Eckes, Maxi; Dove, Sophie; Siebeck, Ulrike E.; Grutter, Alexandra S.

2015-09-01

The cleaning behaviour of the bluestreak cleaner wrasse Labroides dimidiatus is extensively used as a model system for understanding cooperation. It feeds mainly on blood-sucking gnathiid isopods and also on the epidermal mucus of client fish; the nutritional quality of these foods, however, is unknown. The epidermal mucus of reef fish contains ultraviolet (UV)-absorbing compounds (mycosporine-like amino acids, MAAs), which are only obtained via the diet; nevertheless, while La. dimidiatus has high amounts of MAAs in its mucus, their source is unknown. Therefore, the energetic value (calories and protein estimated using carbon and nitrogen) and MAA level in gnathiids and mucus from several clients [parrotfishes, wrasses (Labridae), and a snapper (Lutjanidae)] were determined. The energetic value of mucus and gnathiids varied among fishes. Overall, carbon, nitrogen, calories, and protein per dry weight were higher in the mucus of most client species compared to gnathiids. Thus, depending on the client species, mucus may be energetically more advantageous for cleaner wrasse to feed on than gnathiids. UV absorbance, a confirmed proxy for MAA levels, indicated high MAA levels in mucus, whereas gnathiids had no detectable MAAs. This suggests that La. dimidiatus obtain MAAs from mucus but not from gnathiids. Hence, in addition to energy, the mucus of some clients also provides La. dimidiatus with the added bonus of UV-absorbing compounds. This may explain why cleaner fish prefer to feed on mucus over gnathiid isopods. The likely costs and benefits to clients of the removal of UV protecting mucus and parasitic gnathiids, respectively, and the variation in benefits gained by cleaner fish from feeding on these foods may explain some variation in cooperation levels in cleaning interactions.

The aims of this study were to perform a latent profile analysis in a sample of individuals with compulsive buying, to explore the psychiatric comorbidity, and to examine whether or not more severe compulsive buying is associated with greater comorbidity. Compulsive buying measures and SCID data obtained from 171 patients with compulsive buying behavior who had participated in treatment trials at different clinical centers in the U.S. and Germany were analyzed. Latent profile analysis produced two clusters. Overall, cluster 2, included subjects with more severe compulsive buying, and was characterized by higher lifetime as well as current prevalence rates for Axis I and impulse control disorders. Nearly 90% of the total sample reported at least one lifetime Axis I diagnosis, particularly mood (74%) and anxiety (57%) disorders. Twenty-one percent had a comorbid impulse control disorder, most commonly intermittent explosive disorder (11%). Half of the sample presented with at least one current Axis I disorder, most commonly anxiety disorders (44%). Given the substantial psychiatric comorbidity, it is reasonable to question whether or not compulsive buying represents a distinct psychiatric entity vs. an epiphenomenon of other psychiatric disorders.

Online compulsive buying is a little-studied behavioral disorder. To better understand its clinical aspects by focusing on (i) prevalence rate, (ii) correlation with other addictions, (iii) influence of means of access, (iv) motivations to shop to the internet and (v) financial and time-consuming consequences. Cross-sectional study. 200 students in two different centers of Paris Diderot University - Paris VII. Brief self-questionnaires, to screen online compulsive buying, internet addiction, alcohol and tobacco use disorders, to rate frequency of online purchase by private-sale websites, by advertising banners, by mobile phone or to avoid stores, to rate motivations like "more discreet", "lonelier", "larger variety of products", "more immediate positive feelings", and "cheaper" and to assess the largest amount of online purchasing and the average proportion of monthly earnings, and time spent, both day and night. Prevalence of online compulsive buying was 16.0%, while prevalence of internet addiction was 26.0%. We found no significant relationship with cyberdependence, alcohol or tobacco use disorders. Online compulsive buyers accessed more often shopping online by private-sale websites (56.2% vs 30.5%, p<0.0001) or by mobile phone (22.5% vs 7.9%, p=0.005) and preferred online shopping because of exhaustive offer (p<0.0001) and immediate positive feelings (p<0.0001). Online compulsive buyers spent significantly more money and more time in online shopping. Online compulsive buying seems to be a distinctive behavioral disorder with specific factors of loss of control and motivations, and overall financial and time-consuming impacts. More research is needed to better characterize it. Copyright © 2014 Elsevier Ltd. All rights reserved.

Spray cleaner is a cleaning product containing compressed 1,1-difluoroethane (HFC-152a) to blow dust off electric devices and other sensitive equipment; however, it is also inhaled to induce euphoria. This report describes three cases of death involving HFC-152a inhalation with spray cleaner under different circumstances. In case 1, death was during inhalation for euphoria with which led to having frostbite. In case 2, death may have been associated with suicidal intention. Case 3 was also considered an accidental autoerotic death. In all three cases, HFC-152a was detected at 99.2-136.2mg/l in blood samples, 94.5-191.9 mg/l in urine samples and 3.6-18.4 mg in the gastric contents according to gas chromatography with flame ionization detection. To prevent death associated with HFC-152a inhalation from spray cleaner, the danger of the sudden death should be announced to people, given the ready availability of commercial products containing HFC-152a.

2014-11-30

Based on a literature review, the purpose is to identify the main therapeutic approaches for the compulsive buying disorder, a present time disorder characterized by excessive and uncontrollable concerns or behaviors related to buying or expenses, which may lead to adverse consequences. The systematic review was carried out by searching the electronic scientific bases Medline/Pubmed, ISI, PsycInfo. The search was comprised of full-text articles, written in Portuguese and English, with no time limit or restrictions on the type of study and sample. A total of 1659 references were found and, by the end, 23 articles were selected for this review. From the articles found, it was determined that, although there are case studies and clinical trials underlining the effectiveness of the treatment for compulsive buying, only those studies with a focus on the cognitive-behavioral therapy approach make evident the successful response to the treatment. The publication of new studies on the etiology and epidemiology of the disorder is necessary, in order to establish new forms of treatment and to verify the effectiveness and response of the Brazilian population to the existing protocols.

Urine collection systems with aspiration system for vacuum tubes are becoming increasingly common for urinalysis, especially for microscopic examination of the urine. In this study, we aimed to examine whether vacuum aspiration of the urine sample has any adverse effect on sediment analysis by comparing results from vacuum and non-vacuum urine tubes. The study included totally 213 urine samples obtained from inpatients and outpatients in our hospital. Urine samples were collected to containers with aspiration system for vacuum tubes. Each sample was aliquoted to both vacuum and non-vacuum urine tubes. Urinary sediment analysis was performed using manual microscope. Results were evaluated using chi-square test. Comparison of the sediment analysis results from vacuum and non-vacuum urine tubes showed that results were highly concordant for erythrocyte, leukocyte and epithelial cells (gamma values 1, 0.997, and 0.994, respectively; p < .001). Results were also concordant for urinary casts, crystals and yeast (kappa values 0.815, 0.945 and 1, respectively; p < .001). The results show that in urinary sediment analysis, vacuum aspiration has no adverse effect on the cellular components except on casts.

Compulsive buying disorder: a review and update.

PubMed

Aboujaoude, Elias

2014-01-01

Compulsive buying disorder (CBD) refers to the chronic purchasing of unneeded or unwanted items, causing significant negative consequences. There are no established criteria for CBD, and operational definitions have relied on similarities with OCD, substance use disorders, and impulse control disorders. Compulsive buying disorder is common, affecting 5.8% of the general population, according to one study. Typically, CBD has early onset, frequent comorbidities, and a chronic course. The etiology of CBD is unknown, with biological, psychological and sociocultural factors proposed as likely contributors. Treatment data are limited and suggest addressing comorbid conditions and considering cognitive behavioral therapy, financial and family counseling, selective serotonin reuptake inhibitors, and naltrexone, among other possible interventions, to target CBD. Beyond treatment, educational, legislative and family-based public policy initiatives can likely help individuals with CBD and other excessive spenders.

Student Buy-In Toward Formative Assessments: The Influence of Student Factors and Importance for Course Success †

PubMed Central

Brazeal, Kathleen R.; Couch, Brian A.

2017-01-01

Formative assessment (FA) techniques, such as pre-class assignments, in-class activities, and post-class homework, have been shown to improve student learning. While many students find these techniques beneficial, some students may not understand how they support learning or may resist their implementation. Improving our understanding of FA buy-in has important implications, since buy-in can potentially affect whether students fully engage with and learn from FAs. We investigated FAs in 12 undergraduate biology courses to understand which student characteristics influenced buy-in toward FAs and whether FA buy-in predicted course success. We administered a mid-semester survey that probed student perceptions toward several different FA types, including activities occurring before, during, and after class. The survey included closed-ended questions aligned with a theoretical framework outlining key FA objectives. We used factor analysis to calculate an overall buy-in score for each student and general linear models to determine whether certain characteristics were associated with buy-in and whether buy-in predicted exam scores and course grades. We found that unfixed student qualities, such as perceptions, behaviors, and beliefs, consistently predicted FA buy-in, while fixed characteristics, including demographics, previous experiences, and incoming performance metrics, had more limited effects. Importantly, we found that higher buy-in toward most FA types predicted higher exam scores and course grades, even when controlling for demographic characteristics and previous academic performance. We further discuss steps that instructors can take to maximize student buy-in toward FAs. PMID:28512523

Maraz, Aniko; Griffiths, Mark D; Demetrovics, Zsolt

2016-03-01

To estimate the pooled prevalence of compulsive buying behaviour (CBB) in different populations and to determine the effect of age, gender, location and screening instrument on the reported heterogeneity in estimates of CBB and whether publication bias could be identified. Three databases were searched (Medline, PsychInfo, Web of Science) using the terms 'compulsive buying', 'pathological buying' and 'compulsive shopping' to estimate the pooled prevalence of CBB in different populations. Forty studies reporting 49 prevalence estimates from 16 countries were located (n = 32,000). To conduct the meta-analysis, data from non-clinical studies regarding mean age and gender proportion, geographical study location and screening instrument used to assess CBB were extracted by multiple independent observers and evaluated using a random-effects model. Four a priori subgroups were analysed using pooled estimation (Cohen's Q) and covariate testing (moderator and meta-regression analysis). The CBB pooled prevalence of adult representative studies was 4.9% (3.4-6.9%, eight estimates, 10,102 participants), although estimates were higher among university students: 8.3% (5.9-11.5%, 19 estimates, 14,947 participants) in adult non-representative samples: 12.3% (7.6-19.1%, 11 estimates, 3929 participants) and in shopping-specific samples: 16.2% (8.8-27.8%, 11 estimates, 4686 participants). Being young and female were associated with increased tendency, but not location (United States versus non-United States). Meta-regression revealed large heterogeneity within subgroups, due mainly to diverse measures and time-frames (current versus life-time) used to assess CBB. A pooled estimate of compulsive buying behaviour in the populations studied is approximately 5%, but there is large variation between samples accounted for largely by use of different time-frames and measures. © 2016 Society for the Study of Addiction.

Blue-collar workers have an increased risk of cardiovascular disease. Accordingly, elevated levels of biomarkers related to risk of cardiovascular disease, such as high-sensitive C-reactive protein, have been observed among blue-collar workers. The objective was to examine whether an aerobic exercise worksite intervention changes the level of inflammation biomarkers among cleaners. The design was a cluster-randomized controlled trial with 4-month worksite intervention. Before the 116 cleaners aged 18-65 years were randomized, they signed an informed consent form. The reference group (n = 59) received lectures, and the aerobic exercise group (n = 57) performed worksite aerobic exercise (30 min twice a week). Levels of biomarkers (high-sensitive C-reactive protein, fibrinogen, cholesterol, low- and high-density lipoprotein cholesterol and triglyceride) were collected at baseline and after 4 months. A repeated-measure, multi-adjusted, mixed-model intention-to-treat analysis was applied to compare between-group differences. The study was registered as ISRCTN86682076. Significant (p < 0.05) between-group reductions from baseline to follow-up were found for high-sensitive C-reactive protein (-0.54 ± 0.20 µg/ml; 95% CI -0.94, -0.14), low-density lipoprotein cholesterol (-0.32 ± 0.11 mmol/L; 95% CI -0.54, -0.10) and the ratios of LDL/HDL (-0.30 ± 0.08; 95% CI -0.46, -0.14), and LDL/TC cholesterol (-0.04 ± 0.02; 95% CI -0.07, -0.01). This study indicates that an aerobic exercise intervention among cleaners leads to reduced levels of high-sensitive C-reactive protein and low-density lipoprotein cholesterol, and an unaltered level of fibrinogen. The aerobic exercise seems to improve inflammatory levels and lipoprotein profile among cleaners, with no signs of cardiovascular overload.

In this study, a novel cleaner production process of citric acid was proposed to completely solve the problem of wastewater management in citric acid industry. In the process, wastewater from citric acid fermentation was used to produce methane through anaerobic digestion and then the anaerobic digestion effluent was further treated with air stripping and electrodialysis before recycled as process water for the later citric acid fermentation. This proposed process was performed for 10 batches and the average citric acid production in recycling batches was 142.4±2.1g/L which was comparable to that with tap water (141.6g/L). Anaerobic digestion was also efficient and stable in operation. The average chemical oxygen demand (COD) removal rate was 95.1±1.2% and methane yield approached to 297.7±19.8mL/g TCODremoved. In conclusion, this novel process minimized the wastewater discharge and achieved the cleaner production in citric acid industry. Copyright © 2016 Elsevier Ltd. All rights reserved.

The influence of air cleaners on indoor particulate matter components and oxidative potential in residential households in Beijing.

In many developing regions with poor air quality, the use of air filtration devices to clean indoor air is growing rapidly. In this study, we collected indoor, outdoor and personal exposure filter-based samples of fine particulate matter (PM 2.5 ) with both properly operating, and sham air cleaners in six Beijing residences from July 24th to August 17th, 2016. Mass concentrations of PM 2.5 and several health relevant components of PM 2.5 including organic carbon, elemental carbon, sulfate, nitrate, ammonium, and 21 selected metals, were analyzed to evaluate the effectiveness of air cleaners. The effect of air purification on PM 2.5 reactive oxygen species (ROS) activity, a metric of the oxidative potential of the aerosol, was also evaluated. The average indoor PM 2.5 concentration during true filtration was 8.47μg/m 3 , compared to 49.0μg/m 3 during sham filtration; thus, air cleaners can significantly reduce the indoor PM 2.5 concentration to well below WHO guideline levels and significantly lower all major components of PM 2.5 . However, the utility of air cleaners in reducing overall personal exposure to PM 2.5 and its components was marginal in this study: the average personal exposure PM 2.5 concentration was 67.8 and 51.1μg/m 3 during true and sham filtration respectively, and it is likely due to the activity patterns of the subjects. Short-term exposure contributions from environments with high PM 2.5 concentrations, including exposure to traffic related emissions as well as uncharacterized indoor microenvironments, likely add substantially to the total PM 2.5 exposure burden. The toxicity assay indicates that the air cleaners can also significantly reduce ROS activity in the indoor environment; however, this decrease did not translate to a reduction in personal exposure. Elemental carbon, lead, and arsenic were well-correlated with the ROS activity, thus adding to the knowledge base of drivers for ROS activity. Copyright © 2018 Elsevier B.V. All rights

Experimental analysis of the relationship between depressed mood and compulsive buying.

PubMed

Kyrios, Michael; McQueen, Paul; Moulding, Richard

2013-06-01

Compulsive buying is a serious but understudied problem, where individuals are unable to resist or control their buying behaviour, leading to substantial social and financial problems. To date there has been a lack of experimental research into the disorder. The relationship between mood and compulsive buying was examined in compulsive buyers (N = 18) and non-clinical controls (N = 17), using experimental information-processing paradigms. In study 1, it was expected that, if buying behaviours function as a coping strategy for depressed mood, then an induction of depressed mood would lead to an enhanced memory for appealing consumer-objects in compulsive buyers, but not controls. In study 2, we examined the association between emotional and functional constructs and consumer items. It was expected that compulsive buyers would show stronger semantic relationships and thus better episodic memory for object-emotion pairs, relative to object-function pairs, for appealing items. Unexpectedly, in study 1 the memory-facilitating effect of depressed mood was evident among control participants and absent among compulsive buyers. In study 2, compulsive buyers showed a lesser association of undesirable objects with positive emotional concepts than did non-clinical controls, and compulsive buyers were found to more strongly associate all consumer items with emotional concepts than with concepts of function. Key limitations were low power and possible floor effects due to error frequency data. These findings provide insights into the processes underlying CB phenomena, in particular supporting the role of mood in compulsive buying. Copyright © 2012 Elsevier Ltd. All rights reserved.

Searching online to buy commonly prescribed psychiatric drugs.

PubMed

Monteith, Scott; Glenn, Tasha

2018-02-01

The use of online pharmacies to purchase prescription drugs is increasing. The patient experience when searching to buy commonly prescribed psychiatric drugs was investigated. Using the search term "buy [drug name] online" in Google, 38 frequently prescribed drugs, including 13 with a high potential for abuse, were searched by brand and generic names. The first page of results were analyzed, including with pharmacy certification checkers and ICANN WHOIS. Search results for all drugs yielded 167 pharmacies, of which 147 (88%) did not require a prescription. Considering all searches, the average number of pharmacies requiring a prescription was 2.7 for a brand name drug and 2.4 for a generic name. A phrase like "buy without a prescription" usually appeared on the search results page. All results for drugs with a high potential for abuse were for illegal pharmacies. Information from certification agencies was often conflicting. Most pharmacies were registered internationally. Patients searching online to purchase prescription psychiatric drugs are presented predominantly with illegal pharmacies, and find conflicting certification data. Patient education should address typical search results. Societal pressures may increase the use of online pharmacies including prescription drug costs, stigma, loss of trust in expert opinion, and the changing patient role. Copyright © 2017 Elsevier B.V.

Studies have shown a negative social gradient in the incidence of early retirement. To prevent undesired early retirement, there is a need for knowledge of specific predictors in addition to social factors with a limited potential for change. The main purpose of this study was to examine musculoskeletal complaints and working conditions as predictors of early retirement among Danish female cleaners. Using Cox regression with an adjustment for extraneous factors, we compared the risk of disability pension and retirement before the nominal retirement age (65 years) in an 11-year cohort study with registry-based follow-up of 1430 female cleaners and 579 shop assistants. In subsequent analyses of female cleaners, disability pension and voluntary early retirement were modeled according to work characteristics and upper extremity complaints. The adjusted hazard rate (HR) for disability pension among cleaners compared to the control group was 2.27 (95% CI 1.58 to 3.28) and, for voluntary early retirement, 1.01 (95% CI 0.85 to 1.20). In the subset of cleaners, the predictors of disability pension were persistent shoulder pain HR: 1.98 (95% CI 1.47 to 2.67), elbow pain HR: 1.41 (95% CI 1.02 to 1.94) and symptoms of nerve entrapment of the hand HR: 1.58 (95% CI 1.14 to 2.20). Predictors of voluntary early retirement were persistent shoulder pain HR: 1.40 (95% CI 1.16 to 1.67) and floor mopping for more than 10 h per week HR: 1.20 (95% CI 1.03 to 1.40). Cleaners have a twofold higher risk of disability pension compared to the control group. Risk factors for disability pension among cleaners were persistent shoulder and elbow pain together with symptoms of nerve entrapment of the hand. The findings of specific health related predictors of early retirement could be used in secondary prevention with targeted temporary reduced workload.

Beyond the Big Five: the role of extrinsic life aspirations in compulsive buying.

PubMed

Otero-López, José M; Villardefrancos Pol, Estíbaliz; Castro Bolaño, Cristina

2017-11-01

The integration of units of differing natures which are found in different parts of some multilevel personality models is one of the most thought-provoking paths in contemporary research. In the field of compulsive buying, little is known about the interrelationships between the comparative and stable units such as personality traits (basic tendencies or Level I units) and goals (a kind of middle-level unit) which are more related to motivational processes and intentions governing people’s behavior. Self-reporting measures of compulsive buying, Big Five personality traits, and extrinsic life aspirations were administered to a general population sample consisting of 2,159 participants aged 15 to 65 (48.1% males; Mage= 35.4, SD= 13.24). Our results confirmed statistically significant associations with compulsive buying for the traits as well as the extrinsic goals. Furthermore, an important relationship between both levels in personality – traits vs . extrinsic life aspirations – was found. Finally, extrinsic life aspirations (specially, image, popularity, and conformity) contribute to the potentiation of the prediction of compulsive buying beyond the Five Factor Model. Current findings emphasize the advisability of considering both levels in personality, traits and middle-level units like life aspirations, not only in the prediction of compulsive buying, but also as potential targets for preventive and treatment programs.

The aim of this study was to estimate the prevalence of compulsive buying and its association with sociodemographic characteristics and depressive symptoms in a nationally representative sample of the German population using the validated German version of the Compulsive Buying Scale (CBS; Faber and O'Guinn, 1992) in order to have a direct comparison with U.S. findings. The point prevalence of compulsive buying in the weighted representative sample (N=2,350) was estimated to be 6.9%. This was somewhat higher than the percentage in the American sample assessed in 2004 (5.8%). No significant difference was found between women and men (6.9% and 6.8%, respectively). Age was inversely related to the prevalence of compulsive buying. Individuals with compulsive buying reported more depressive symptoms assessed via the German version of the Brief Patient Health Questionnaire Mood Scale (PHQ-9). Further research on this topic is needed to establish a clearer delineation of when excessive buying is clinically significant and should be treated and how it could be prevented.

Long-Term Effects of the Cleaner Fish Labroides dimidiatus on Coral Reef Fish Communities

PubMed Central

Waldie, Peter A.; Blomberg, Simon P.; Cheney, Karen L.; Goldizen, Anne W.; Grutter, Alexandra S.

2011-01-01

Cleaning behaviour is deemed a mutualism, however the benefit of cleaning interactions to client individuals is unknown. Furthermore, mechanisms that may shift fish community structure in the presence of cleaning organisms are unclear. Here we show that on patch reefs (61–285 m2) which had all cleaner wrasse Labroides dimidiatus (Labridae) experimentally removed (1–5 adults reef−1) and which were then maintained cleaner-fish free over 8.5 years, individuals of two site-attached (resident) client damselfishes (Pomacentridae) were smaller compared to those on control reefs. Furthermore, resident fishes were 37% less abundant and 23% less species rich per reef, compared to control reefs. Such changes in site-attached fish may reflect lower fish growth rates and/or survivorship. Additionally, juveniles of visitors (fish likely to move between reefs) were 65% less abundant on removal reefs suggesting cleaners may also affect recruitment. This may, in part, explain the 23% lower abundance and 33% lower species richness of visitor fishes, and 66% lower abundance of visitor herbivores (Acanthuridae) on removal reefs that we also observed. This is the first study to demonstrate a benefit of cleaning behaviour to client individuals, in the form of increased size, and to elucidate potential mechanisms leading to community-wide effects on the fish population. Many of the fish groups affected may also indirectly affect other reef organisms, thus further impacting the reef community. The large-scale effect of the presence of the relatively small and uncommon fish, Labroides dimidiadus, on other fishes is unparalleled on coral reefs. PMID:21731670

Electroweak vacuum instability and renormalized Higgs field vacuum fluctuations in the inflationary universe

NASA Astrophysics Data System (ADS)

Kohri, Kazunori; Matsui, Hiroki

2017-08-01

In this work, we investigated the electroweak vacuum instability during or after inflation. In the inflationary Universe, i.e., de Sitter space, the vacuum field fluctuations < δ phi 2 > enlarge in proportion to the Hubble scale H2. Therefore, the large inflationary vacuum fluctuations of the Higgs field < δ phi 2 > are potentially catastrophic to trigger the vacuum transition to the negative-energy Planck-scale vacuum state and cause an immediate collapse of the Universe. However, the vacuum field fluctuations < δ phi 2 >, i.e., the vacuum expectation values have an ultraviolet divergence, and therefore a renormalization is necessary to estimate the physical effects of the vacuum transition. Thus, in this paper, we revisit the electroweak vacuum instability from the perspective of quantum field theory (QFT) in curved space-time, and discuss the dynamical behavior of the homogeneous Higgs field phi determined by the effective potential V eff( phi ) in curved space-time and the renormalized vacuum fluctuations < δ phi 2 >ren via adiabatic regularization and point-splitting regularization. We simply suppose that the Higgs field only couples the gravity via the non-minimal Higgs-gravity coupling ξ(μ). In this scenario, the electroweak vacuum stability is inevitably threatened by the dynamical behavior of the homogeneous Higgs field phi, or the formations of AdS domains or bubbles unless the Hubble scale is small enough H< ΛI .

A review of compulsive buying disorder

PubMed Central

BLACK, DONALD W

2007-01-01

Compulsive buying disorder (CBD) is characterized by excessive shopping cognitions and buying behavior that leads to distress or impairment. Found worldwide, the disorder has a lifetime prevalence of 5.8% in the US general population. Most subjects studied clinically are women (~80%), though this gender difference may be artifactual. Subjects with CBD report a preoccupation with shopping, prepurchase tension or anxiety, and a sense of relief following the purchase. CBD is associated with significant psychiatric comorbidity, particularly mood and anxiety disorders, substance use disorders, eating disorders, and other disorders of impulse control. The majority of persons with CBD appear to meet criteria for an Axis II disorder, although there is no special "shopping" personality. Compulsive shopping tends to run in families, and these families are filled with mood and substance use disorders. There are no standard treatments. Psychopharmacologic treatment studies are being actively pursued, and group cognitive-behavioral models have been developed and are promising. Debtors Anonymous, simplicity circles, bibliotherapy, financial counseling, and marital therapy may also play a role in the management of CBD. PMID:17342214

Chour, V

2001-01-01

This paper reports on integrated watershed-based protection and sustainable use of water resources to increase the effectiveness of water pollution abatement. The approach includes improvements in end-of-pipe waste-water treatment technologies and implementation of Cleaner Production (CP) principles and policies within the watershed. An example of the general effectiveness of this approach is illustrated by the Czech Odra River Cleaner Production Project where reductions in pollution were achieved with improved industrial production. The CP theme is worth considering as an important challenge for the IWA.

Firms that are dynamic and prepared to implement environmental strategies have a potential competitive advantage over their industry counterparts. Therefore, it is important to understand, what capabilities are required to implement proactive environmental strategies. The paper discusses the attributes of innovative capability required by firms in order to adopt pollution prevention and cleaner technology strategies. Empirical results show that process and behavioral innovativeness are required by firms to implement a pollution prevention strategy. In addition to process and behavioral innovativeness, firms need a top management with high risk-taking ability as well as market, product, and strategic innovativeness to implement a cleaner technology strategy. The paper proposes some important managerial implications on the basis of the above research findings. Copyright © 2015 Elsevier Ltd. All rights reserved.

[Where do Parisian teenagers buy their cigarettes?

PubMed

Dautzenberg, B; Birkui, P

2017-03-01

The objective of this work was to assess the background of the implementation of the ban of tobacco sales to minors before the change of French law in 2016. The analysis focused on two questions to teenagers on buying tobacco, added to the four cross-sectional annual surveys of the association "Paris Sans Tabac" from 2012 to 2015. In total, 7025 schoolchildren (12-15 years old), 3299 high school students (16-17 years old) and 3243 adult students (18-20 years old) responded. The proportion of daily smokers was respectively 3.2%, 19.0% and 22.0%. The overall smoking rate (daily+occasional) was 13.8%, 37.9% and 39.5% respectively. Among daily smokers, 90.7% of respondents had bought their tobacco from tobacconist. This source was used by 74.6% of daily smokers aged 12-15 years, 92.0% of the 16-17 years old and 94.0% of the18-19 years old teenagers. Drinking more than four glasses of alcohol on the same day or having used cannabis in the preceding month was associated with a greater chance of buying tobacco at the tobacconist. Starting to buy tobacco from a tobacconist below the age of 12 was associated with a high dependence score (HSI=2.4±1.9) compared to those who bought after 15 years (HSI=0.5±0.7) (P<0.001). Before 2016, Parisian teenagers who smoked daily mostly bought their cigarettes from a tobacconist. Copyright © 2016 SPLF. Published by Elsevier Masson SAS. All rights reserved.

Acute effect on ambulatory blood pressure from aerobic exercise: a randomised cross-over study among female cleaners.

High occupational physical activity (OPA) is shown to increase the risk for elevated blood pressure, cardiovascular diseases and mortality. Conversely, aerobic exercise acutely lowers the blood pressure up to 25 h post exercise. However, it is unknown if this beneficial effect also apply for workers exposed to high levels of OPA. Cleaners constitute a relevant occupational group for this investigation because of a high prevalence of OPA and cardiovascular disease. Accordingly, the objective was to investigate the acute effects on ambulatory blood pressure from a single aerobic exercise session among female cleaners. Twenty-two female cleaners were randomised to a cross-over study with a reference and an aerobic exercise session. Differences in 24-h, work hours, leisure time, and sleep ambulatory blood pressure (ABP) were evaluated using repeated measure 2 × 2 mixed-models. After the aerobic exercise session, the 24-h systolic ambulatory blood pressure was significantly lowered by 2.4 mmHg (p < 0.01) compared to the reference session. The 24-h diastolic ABP was unaltered. During work hours, a lowered systolic ABP of 2.2 mmHg (p = 0.02) and a higher diastolic ABP of 1.5 mmHg (p = 0.03) were found after the aerobic exercise session. During leisure time, the systolic ABP was lowered by 1.7 mmHg (p = 0.04) and the diastolic ABP was unaltered. During sleep, the systolic and diastolic ABP was unaltered. A single aerobic exercise session lowered 24-h systolic ABP of 2.4 mmHg. Thus, an aerobic exercise session seems to be beneficial for lowering the risk of hypertension among cleaners.

Development of High Interruption Capability Vacuum Circuit Breaker -Technology of Vacuum Arc Control-

NASA Astrophysics Data System (ADS)

Niwa, Yoshimitsu; Kaneko, Eiji

Vacuum circuit breakers (VCB) have been widely used for power distribution systems. Vacuum Interrupters, which are the current interruption unit, have been increased its interruption capability with the development of vacuum arc control technology by magnetic field. There are three major type electrodes: disk shaped electrodes, radial magnetic field electrodes, axial magnetic field (AMF) electrodes. In the disk shaped electrode, the vacuum arc between the electrodes is not controlled. In the AMF electrode, the vacuum arc is diffused and stabilized by an axial magnetic field, which is parallel to the arc current. In the last type of electrodes, the vacuum arc column is rotated by magnetic force generated by the current flowing in the electrodes. The interruption current and the voltage of one break VCB is increased to 100 kA, 144 kV respectively. This paper describes basic configurations and functions of VCB, vacuum arc control technology in vacuum interrupters, recent researches and applications of VCB.

2009-05-01

The bactericidal efficacy of 1.00-4.50% glycine-type amphoteric surfactant (Gly) was evaluated by measuring its microorganism removal rate in denture plaque. Physical and mechanical properties such as surface roughness, color difference, and bending strength of two different denture base resins were determined before and after cleaning in Gly solutions, a commercial denture cleaner, and tap water. The microorganism removal rates of all the Gly solutions were higher than those of a commercial enzymatic denture cleaner (Polident) (p>0.05). The removal rate of Candida spp. by Polident was not significantly different from the removal rate using water. Changes in the surface roughness and color difference among the specimens were slight. There were no significant differences in the bending strengths of the two resins for all concentrations of Gly solution (p>0.05). These results suggested that glycine-type amphoteric surfactant solution may be effective as a denture cleaner in conjunction with an ultrasonic cleaning device.

In many cities, dry cleaners using perchloroethylene are frequently located in multifamily residential buildings and often cause elevated indoor air levels of perchloroethylene throughout the building. To assess individual perchloroethylene exposures associated with co-located dry cleaners, we measured perchloroethylene in residential indoor air, and in blood and breath of adults and children residing in buildings with a dry cleaner as part of the New York City (NYC) Perc Project. We also measured perchloroethylene in indoor air, and in blood and breath of residents of buildings without a dry cleaner for comparison. Here, we evaluate whether an environmental disparity in perchloroethylene exposures is present. Study participants are stratified by residential building type (dry cleaner or reference) and socioeconomic characteristics (race/ethnicity and income); measures of perchloroethylene exposure are examined; and, the influence of stratified variables and other factors on perchloroethylene exposure is assessed using multivariate regression. All measures of perchloroethylene exposure for residents of buildings with a dry cleaner indicated a socioeconomic disparity. Mean indoor air perchloroethylene levels were about five times higher in minority (82.5 ug/m(3)) than in non-minority (16.5 ug/m(3)) households, and about six times higher in low-income (105.5 ug/m(3)) than in high income (17.8 ug/m(3)) households. Mean blood perchloroethylene levels in minority children (0.27 ng/mL) and adults (0.46 ng/mL) were about two and three times higher than in non-minority children (0.12 ng/mL) and adults (0.15 ng/mL), respectively. Mean blood perchloroethylene levels in low income children (0.34 ng/mL) and adults (0.62 ng/mL) were about three and four times higher than in high income children (0.11 ng/mL) and adults (0.14 ng/mL), respectively. A less marked socioeconomic disparity was observed in perchloroethylene breath levels with minority and low income residents having

With increasing population and urban development, societies grow more and more concerned over balancing the need to maintain adequate water supplies with that of ensuring the quality of surface and groundwater resources. For example, multiple stressors such as overfishing, runoff of nutrients from agricultural fields and confined animal feeding lots, and pathogens in urban stormwater can often overwhelm a single water body. Mitigating just one of these problems often depends on understanding how it relates to others and how stressors can vary in temporal and spatial scales. Researchers are now in a position to answer questions about multiscale, spatiotemporally distributed hydrologic and environmental phenomena through the use of remote and embedded networked sensing technologies. It is now possible for data streaming from sensor networks to be integrated by a rich cyberinfrastructure encompassing the innovative computing, visualization, and information archiving strategies needed to cope with the anticipated onslaught of data, and to turn that data around in the form of real-time water quantity and quality forecasting. Recognizing this potential, NSF awarded $2 million to a coalition of 12 institutions in July 2005 to establish the CLEANER Project Office (Collaborative Large-Scale Engineering Analysis Network for Environmental Research; http://cleaner.ncsa.uiuc.edu). Over the next two years the project office, in coordination with CUAHSI (Consortium of Universities for the Advancement of Hydrologic Science, Inc.; http://www.cuahsi.org), will work together to develop a plan for a WATer and Environmental Research Systems Network (WATERS Network), which is envisioned to be a collaborative scientific exploration and engineering analysis network, using high performance tools and infrastructure, to transform our scientific understanding of how water quantity, quality, and related earth system processes are affected by natural and human-induced changes to the environment

Compulsive buying is a common disorder found worldwide. Although recent research has shed light into the prevalence, etiology and clinical correlates of compulsive buying disorder, less is known about gender differences. To address this empirical gap, we assessed potential gender differences in demographic and psychiatric co-morbidities in a sample of 171 compulsive buyers (20 men and 151 women) voluntarily seeking treatment in São Paulo, Brazil. A structured clinical interview confirmed the diagnosis of compulsive buying. Of the 171 participants, 95.9% (n = 164) met criteria for at least one co-morbid psychiatric disorder. The results found that male and female compulsive buyers did not differ in problem severity as assessed by the Compulsive Buying Scale. However, several significant demographic and psychiatric differences were found in a multivariate binary logistic regression. Specifically, male compulsive buyers were more likely to report being non-heterosexual, and reported fewer years of formal education. In regards to psychiatric co-morbidities, male compulsive buyers were more likely to be diagnosed with sexual addiction, and intermittent explosive disorder. Conversely, men had lower scores on the shopping subscale of the Shorter PROMIS Questionnaire. The results suggest that male compulsive buyers are more likely to present with co-morbid psychiatric disorders. Treatment planning for compulsive buying disorder would do well to take gender into account to address for potential psychiatric co-morbidities. PMID:27907082

2014-11-01

In this single-blind, crossover study, the difference between a brushless tooth cleaner and a soft toothbrush was studied to compare plaque removal efficiency. The sample was composed of 15 human subjects who were categorized into two groups. Group 1 was composed of subjects randomly assigned to the brushless tooth cleaner for the first two weeks. Group 2 was composed of those randomly assigned to begin the study using the soft toothbrush. After two weeks of brushing with their assigned device, subjects returned to their normal modality to brush their teeth for one week. For the last two weeks of the study, subjects were told to brush with the opposite device they were originally assigned to at the beginning of the trial. Investigators recorded the subjects' gingival indices (based on probe depths) and Quigley scores (based on plaque indices using disclosing solution) at the beginning of week one, the end of week two, the end of week three and the end of week five. The main outcomes in this study were the Silness Loe Index (SLI) and the Quigley Hein Index (QHI). The SLI was assessed on the buccal, lingual, mesial and distal surfaces of six teeth, for a total of 24 surfaces. The QHI was assessed on the buccal and lingual surfaces of six teeth, for a total of 12 surfaces. Each index was measured at each visit by the sum total score divided by the total number of surfaces. The data were analyzed separately using a mixed-effects repeated measures analysis of variance (RMANOVA) for crossover designs. Results indicate that, according to the SLI, there is no significant difference between the two treatments after the first or second weeks. However, based on the QHI, statistically significant differences existed between the two treatments after week one and two. After week one, the soft toothbrush use had a higher QHI than the brushless tooth cleaner. After week two, the brushless tooth cleaner had a higher QHI than the soft toothbrush.

Lejoyeux, Michel; Richoux-Benhaim, Charlotte; Betizeau, Annabelle; Lequen, Valérie; Lohnhardt, Hannah

2011-01-01

This study tried to determine the prevalence of compulsive buying (CB) and to identify among compulsive buyers a specific relation to money, a different buying style, and a lowered level of self-esteem. We included 203 medical students and diagnosed CB with the Mc Elroy criteria and a specific questionnaire. The money attitude was characterized by the Yamauchi and Templer's scale and self-esteem with the Rosenberg scale. 11% of the medical students presented compulsive buying (CB+). Sex ratio and mean ages were comparable in the CB+ and control groups. CB+ students drank less alcohol and smoked an equivalent number of cigarettes. Compulsive buyers had higher scores of distress (tendency to be hesitant, suspicious, and doubtful attitude toward situations involving money) and bargain missing (fear of missing a good opportunity to buy an item). They bought more often gifts for themselves, items they use less than expected and choose goods increasing their self-esteem. Their score of self-esteem was not different from the one from controls.

Sexual behaviour and substance use patterns amongst adolescent truck cleaners and risk of HIV / AIDS.

PubMed

Bansal, R K

1992-01-01

This study was conducted at transport nagar in Indore, a major industrial and commercial center of Madhya Pradesh. Usually each truck has a staff of 3, comprising 1 senior driver, 1 junior driver, and a cleaner, usually a child or an adolescent. 210 such adolescent truck cleaners were surveyed by random sampling of the parked trucks present in the transport nagar. A semi-structured questionnaire was administered to these adolescents using the oral interview technique. The age distribution of the adolescents indicated that 17 were 15-16 years old, 63 were 16-17, 61 were 17-18, and 69 were 18-19. When the income was low, the owners or the senior drivers provided the meals and minor expenses. 80% of the adolescents were illiterate, 10.5% were literate, 6.2% had primary education, and 3.3% had middle school education. 88.1% of the cleaners were away from home for 24-28 days a month, 7.1% for less than 24 days, and 4.8% for over 28 days. 25.2% of the cleaners had a history of sexual activity, commonly with prostitutes. 88.6% of the senior drivers regularly visited prostitutes, and in many cases the adolescents' payment to the prostitute was financed by the senior driver. 94.3% of these adolescents had engaged in unprotected sexual intercourse, and the remaining 5.7% had used condoms infrequently. 98.5% of them had not heard of HIV and AIDS. 4.3% had a history of sexually transmitted diseases and had been treated by general practitioners. Substance abuse was fairly common among these young people (140 smoked, 9 chewed tobacco, 2 used opium, and 2 used alcohol more than twice per week), and the cost for those substances was primarily met by the senior truck driver or the owner. The trend was similar for sexual activity, as 25.2% had engaged in sex (12.9% once, 7.1% twice, and 5.2% several times). Special programs are required for these adolescents to educate them about the risks of unprotected sex and drugs in order to prevent them from contracting HIV/AIDS.

Evolution and diversification of National Cleaner Production Centres (NCPCs).

PubMed

Van Berkel, Rene

2010-07-01

Since 1994 UNIDO and UNEP cooperate in a Programme to establish National Cleaner Production Centres (NCPCs) as a mechanism for delivery of Cleaner Production (CP) services to businesses, governments and other organisations. In 2007, 38 NCPCs were operational in 37 developing and transition countries. While initially set up in near-identical ways in each country, over time NCPCs evolved in response to both programme-internal and country-level factors. The resulting diversity among NCPCs is described and analysed here. Differentiation and specialisation had occurred in service areas or topics both within and between NCPCs, however without a clear strategy for integration and synergy. NCPCs were becoming part of expanding networks of business services providers nationally forcing some to focus on audit and training services (tier 1), and others on specialist services in CP technology and/or policy (tier 2) and/or networking services (tier 3). All NCPCs were on a trajectory from a project management organisation to a nationally-owned entity. The different management requirements were not proactively managed and technical aspects of CP service delivery overshadowed institutional and governance aspects of establishing and operating the NCPC institution. Differences in service delivery methods between NCPCs are most evident in three service areas: CP assessments; policy advice; and transfer of Environmentally Sound Technologies. It is argued here that understanding root causes and benefits of this presently-observed differentiation, could lay the foundation for capturing and advancing best practice CP concepts, methods and policies. This in turn would enable strategic planning for customised interventions and support at the national level. Copyright 2010 Elsevier Ltd. All rights reserved.

Impulsivity and compulsive buying are associated in a non-clinical sample: an evidence for the compulsivity-impulsivity continuum?

PubMed

Paula, Jonas J de; Costa, Danielle de S; Oliveira, Flavianne; Alves, Joana O; Passos, Lídia R; Malloy-Diniz, Leandro F

2015-01-01

Compulsive buying is controversial in clinical psychiatry. Although it is defined as an obsessive-compulsive disorder, other personality aspects besides compulsivity are related to compulsive buying. Recent studies suggest that compulsivity and impulsivity might represent a continuum, with several psychiatric disorders lying between these two extremes. In this sense, and following the perspective of dimensional psychiatry, symptoms of impulsivity and compulsivity should correlate even in a non-clinical sample. The present study aims to investigate whether these two traits are associated in a healthy adult sample. We evaluated 100 adults, with no self-reported psychiatric disorders, using the Barratt Impulsiveness Scale-11 and two scales of compulsive buying. Using multiple linear regressions, we found that impulsivity accounted for about 15% of variance in the compulsive-buying measure. Our results suggest that an association between impulsivity and compulsive buying occurs even in non-clinical samples, evidence that compulsivity and impulsivity might form a continuum and that compulsive buying might be an intermediate condition between these two personality traits.

Effect of an aerobic exercise intervention on cardiac autonomic regulation: A worksite RCT among cleaners.

2017-02-01

The aim of this randomized controlled trial (RCT) was to determine whether aerobic exercise during work hours affects cardiac autonomic regulation in cleaners characterized by high levels of occupational physical activity and poor cardiorespiratory fitness. Eligible cleaners (n=116) were randomized to an aerobic exercise group (n=59) or a reference group (n=57) with lectures. The intervention group received two 30-min sessions per week of supervised aerobic exercise over 4months. Diurnal measurements of heart rate variability (HRV) and physical activity (accelerometry) were obtained at baseline and at 4-month follow-up. Time and frequency domain indices of HRV were derived during work, leisure time and sleep to evaluate cardiac autonomic regulation. Linear mixed models were used to determine the effect of the intervention on HRV indices, with adjustment for age, gender and daily use of antihypertensive and/or heart medication. Compared with the reference group, the exercise group increased all HRV indices apart from a reduction in LF/HF ratio from baseline to follow-up both during work (p<0.05) and leisure (p<0.05). In contrast, during sleep, the HRV indices tended to decrease in the exercise group compared with the reference group from baseline to follow-up, being significant for the HF spectral component (p=0.03). Among cleaners, a worksite aerobic exercise intervention improved cardiac autonomic regulation during work and leisure, but not during sleep. The health effect of this contrasting change in autonomic regulation needs further investigation. Copyright © 2016 Elsevier Inc. All rights reserved.

Australian beef consumers have different preferences given their characteristics and the effect on expected quality of cues related to health, production process and eating experience. Beef brands using Meat Standards Australia (MSA) grades can help to signal quality and reduce consumers' uncertainty when shopping. The objective of this study is to identify the characteristics of beef buyers and their perceptions about product attributes that affect the propensity to buy branded beef. Binary logistic models were applied identifying differences between all respondents and the potential target market, including buyers in medium to high income segments, and between buyers in the target market who would buy branded beef for taste and health reasons. Variables increasing the propensity to buy branded beef include previous experience, appreciation for branded cuts and concern about quality more than size. Finally, variations in preferences for marbling and cut were found between buyers who would buy branded beef for taste and health reasons. Copyright © 2013 Elsevier Ltd. All rights reserved.

Kominsky, J.R.; Freyberg, R.W.; Chesson, J.

The research study examined the effectiveness of dry vacuuming and wet cleaning for the removal of asbestos fibers from carpet, and evaluated the potential for fiber reentrainment during carpet cleaning activities. Routine carpet cleaning operations using high-efficiency particulate air (HEPA) filtered dry vacuum cleaners and HEPA-filtered hot-water extraction cleaners were simulated on carpet artificially contaminated with asbestos fibers. Overall, wet cleaning the carpet with a hot-water extraction cleaner reduced the level of asbestos contamination by approximately 70 percent. There was no significant evidence of either an increase or a decrease in the asbestos concentration after dry vacuuming. The level ofmore » asbestos contamination had no significant effect on the difference between the carpet asbestos concentrations before and after cleaning.

Power recovery of silicone encapsulated and glass covered photovoltaic modules, exposed for two years to a suburban environment, was measured after washing with a variety of cleaners including detergents, abrasive soap, and hydrocarbon solvents. Silicone encapsulated modules in operating environments may experience significant power losses or require extensive periodic cleaning. Glass front-faced modules in similar situations are much less affected. Organic hydrocarbon solvents or abrasives were found to be about five times more effective than mild detergents in cleaning encapsulated modules.

Testing performance in controlled laboratory experiments is a powerful tool for understanding the extent and evolution of cognitive abilities in non-human animals. However, cognitive testing is prone to a number of potential biases, which, if unnoticed or unaccounted for, may affect the conclusions drawn. We examined whether slight modifications to the experimental procedure and apparatus used in a spatial task and reversal learning task affected performance outcomes in the bluestreak cleaner wrasse, Labroides dimidiatus (hereafter "cleaners"). Using two-alternative forced-choice tests, fish had to learn to associate a food reward with a side (left or right) in their holding aquarium. Individuals were tested in one of four experimental treatments that differed slightly in procedure and/or physical set-up. Cleaners from all four treatment groups were equally able to solve the initial spatial task. However, groups differed in their ability to solve the reversal learning task: no individuals solved the reversal task when tested in small tanks with a transparent partition separating the two options, whereas over 50% of individuals solved the task when performed in a larger tank, or with an opaque partition. These results clearly show that seemingly insignificant details to the experimental set-up matter when testing performance in a spatial task and might significantly influence the outcome of experiments. These results echo previous calls for researchers to exercise caution when designing methodologies for cognition tasks to avoid misinterpretations.

Vacuum fluctuations in an ancestor vacuum: A possible dark energy candidate

NASA Astrophysics Data System (ADS)

Aoki, Hajime; Iso, Satoshi; Lee, Da-Shin; Sekino, Yasuhiro; Yeh, Chen-Pin

2018-02-01

We consider an open universe created by bubble nucleation, and study possible effects of our "ancestor vacuum," a de Sitter space in which bubble nucleation occurred, on the present universe. We compute vacuum expectation values of the energy-momentum tensor for a minimally coupled scalar field, carefully taking into account the effect of the ancestor vacuum by the Euclidean prescription. We pay particular attention to the so-called supercurvature mode, a non-normalizable mode on a spatial slice of the open universe, which has been known to exist for sufficiently light fields. This mode decays in time most slowly, and may leave residual effects of the ancestor vacuum, potentially observable in the present universe. We point out that the vacuum energy of the quantum field can be regarded as dark energy if mass of the field is of order the present Hubble parameter or smaller. We obtain preliminary results for the dark energy equation of state w (z ) as a function of the redshift.

2013-01-01

The prevalence of chronic trapezius myalgia is high in women with high exposure to awkward working positions, repetitive movements and movements with high precision demands. The mechanisms behind chronic trapezius myalgia are not fully understood. The purpose of this study was to explore the differences in protein content between healthy and myalgic trapezius muscle using proteomics. Muscle biopsies from 12 female cleaners with work-related trapezius myalgia and 12 pain free female cleaners were obtained from the descending part of the trapezius. Proteins were separated with two-dimensional differential gel electrophoresis (2D-DIGE) and selected proteins were identified with mass spectrometry. In order to discriminate the two groups, quantified proteins were fitted to a multivariate analysis: partial least square discriminate analysis. The model separated 28 unique proteins which were related to glycolysis, the tricaboxylic acid cycle, to the contractile apparatus, the cytoskeleton and to acute response proteins. The results suggest altered metabolism, a higher abundance of proteins related to inflammation in myalgic cleaners compared to healthy, and a possible alteration of the contractile apparatus. This explorative proteomic screening of proteins related to chronic pain in the trapezius muscle provides new important aspects of the pathophysiology behind chronic trapezius myalgia. PMID:24023854

Comparing Sex Buyers With Men Who Do Not Buy Sex: New Data on Prostitution and Trafficking.

PubMed

Farley, Melissa; Golding, Jacqueline M; Matthews, Emily Schuckman; Malamuth, Neil M; Jarrett, Laura

2015-08-31

We investigated attitudes and behaviors associated with prostitution and sexual aggression among 101 men who buy sex and 101 age-, education-, and ethnicity-matched men who did not buy sex. Both groups tended to accept rape myths, be aware of harms of prostitution and trafficking, express ambivalence about the nature of prostitution, and believe that jail time and public exposure are the most effective deterrents to buying sex. Sex buyers were more likely than men who did not buy sex to report sexual aggression and likelihood to rape. Men who bought sex scored higher on measures of impersonal sex and hostile masculinity and had less empathy for prostituted women, viewing them as intrinsically different from other women. When compared with non-sex-buyers, these findings indicate that men who buy sex share certain key characteristics with men at risk of committing sexual aggression as documented by research based on the leading scientific model of the characteristics of non-criminal sexually aggressive men, the Confluence Model of sexual aggression. © The Author(s) 2015.

Effort-reward imbalance at work and self-rated health of Las Vegas hotel room cleaners.

PubMed

Krause, Niklas; Rugulies, Reiner; Maslach, Christina

2010-04-01

This study investigates the relationship between effort-reward-imbalance (ERI) at work and self-rated health (SF-36) among 941 Las Vegas hotel room cleaners (99% female, 84% immigrant). Logistic regression models adjust for age, health behaviors, physical workload and other potential confounders. 50% reported ERI and 60% poor or fair general health. Significant associations were found between ERI and all SF-36 health measures. Workers in the upper quartile of the efforts/rewards ratio were 2-5 times more likely to experience poor or fair general health, low physical function, high levels of pain, fatigue, and role limitations due to physical and mental health problems. The cross-sectional design limits causal interpretation of these associations. However, the development of interventions to reduce ERI and to improve general health among room cleaners deserves high priority considering that both high ERI and low self-rated health have predicted chronic diseases and mortality in prospective studies.

Summary statistics, Pearson correlations, and multiple regression analyses. Among participants (n = 410, mean age = 43 y), 76% and 80%, respectively, reported buying and eating DGLV in the past week. Mean consumption was 1.5 cups in the past 3 days. Intentions to buy (r = 0.20, P < .001) and eat (r = 0.23, P < .001) DGLV were positively associated with consumption. Reasoned Action Approach constructs explained 71.2% of the variance in intention to buy, and 60.9% of the variance in intention to eat DGLV. Attitude (β = .63) and self-efficacy (β = .24) related to buying and attitude (β = .60) and self-efficacy (β = .23) related to eating DGLV explained significant amounts of variance in intentions to buy and eat more DGLV. Perceived norm was unrelated to either intention to buy or eat DGLV. Interventions designed for this population of women should aim to improve DGLV-related attitudes and self-efficacy.

A study investigating the association between compulsive buying with measures of anxiety and obsessive-compulsive behavior among internet shoppers.

PubMed

Weinstein, A; Mezig, Hila; Mizrachi, S; Lejoyeux, M

2015-02-01

Compulsive buying is a chronic, repetitive behavior that becomes a primary response to negative events and feelings. Compulsive buyers are obsessed by buying and their behavior occurs in response to negative emotions and results in a decrease in the intensity of negative emotions. Euphoria or relief from negative emotions is the most common consequence of compulsive buying. A large number of studies have investigated the association between compulsive buying and anxiety, and some studies have used the Spielberger trait-state anxiety inventory. Compulsive buying, state and trait anxiety and general obsessive-compulsive measures were assessed among 120 habitual internet shoppers (2+ times a week, 70 men and 50 women). Results showed that Edwards Compulsive Buying scale measures were associated with Spielberger trait and not state anxiety measures. Spielberger Trait anxiety measures were also correlated with measures of Yale-Brown Obsessive-Compulsive scale (Y-Bocs). Finally, there were no sex differences in this sample. The results of this study support existing evidence for an association between compulsive buying and anxiety and they will be discussed in view of current research on comorbidity of behavioural addiction.

Compulsive buying--a growing concern? An examination of gender, age, and endorsement of materialistic values as predictors.

PubMed

Dittmar, Helga

2005-11-01

Compulsive buying is an understudied, but growing, dysfunctional consumer behaviour with harmful psychological and financial consequences. Clinical perspectives treat it as a psychiatric disorder, whereas recent proposals emphasize the increasing endorsement of materialistic values as a cause of uncontrolled buying (e.g. Dittmar, 2004b; Kasser & Kanner, 2004). The present research aims to improve understanding of compulsive buying through examining gender, age, and endorsement of materialistic values as key predictors in three UK questionnaire studies, which sampled individuals who had contacted a self-help organization and residentially matched 'controls' (N = 330), consumer panelists from a multinational corporation (N = 250), and 16- to 18-year-old adolescents (N = 195). The results confirmed previously documented gender differences, and showed that younger people are more prone to compulsive buying. The central findings were that materialistic value endorsement emerged as the strongest predictor of individuals' compulsive buying, and that it significantly mediated the observed age differences.

Most smokers become addicted to tobacco products before they are legally able to purchase these products. We systematically reviewed the literature on protocols to assess underage purchase and their ecological validity. We conducted a systematic search in May 2015 in PubMed and PsycINFO. We independently screened records for inclusion. We conducted a narrative review and examined implications of two types of legal authority for protocols that govern underage buy enforcement in the United States: criminal (state-level laws prohibiting sales to youth) and administrative (federal regulations prohibiting sales to youth). Ten studies experimentally assessed underage buy protocols and 44 studies assessed the association between youth characteristics and tobacco sales. Protocols that mimicked real-world youth behaviors were consistently associated with substantially greater likelihood of a sale to a youth. Many of the tested protocols appear to be designed for compliance with criminal law rather than administrative enforcement in ways that limited ecological validity. This may be due to concerns about entrapment. For administrative enforcement in particular, entrapment may be less of an issue than commonly thought. Commonly used underage buy protocols poorly represent the reality of youths' access to tobacco from retailers. Compliance check programs should allow youth to present themselves naturally and attempt to match the community's demographic makeup.

Influence of Gap Distance on Vacuum Arc Characteristics of Cup Type AMF Electrode in Vacuum Interrupters

NASA Astrophysics Data System (ADS)

Cheng, Shaoyong; Xiu, Shixin; Wang, Jimei; Shen, Zhengchao

2006-11-01

The greenhouse effect of SF6 is a great concern today. The development of high voltage vacuum circuit breakers becomes more important. The vacuum circuit breaker has minimum pollution to the environment. The vacuum interrupter is the key part of a vacuum circuit breaker. The interrupting characteristics in vacuum and arc-controlling technique are the main problems to be solved for a longer gap distance in developing high voltage vacuum interrupters. To understand the vacuum arc characteristics and provide effective technique to control vacuum arc in a long gap distance, the arc mode transition of a cup-type axial magnetic field electrode is observed by a high-speed charge coupled device (CCD) video camera under different gap distances while the arc voltage and arc current are recorded. The controlling ability of the axial magnetic field on vacuum arc obviously decreases when the gap distance is longer than 40 mm. The noise components and mean value of the arc voltage significantly increase. The effective method for controlling the vacuum arc characteristics is provided by long gap distances based on the test results. The test results can be used as a reference to develop high voltage and large capacity vacuum interrupters.

Update on asthma and cleaners

PubMed Central

Zock, Jan-Paul; Vizcaya, David; Le Moual, Nicole

2010-01-01

Purpose of review This paper summarises the recent literature on the relation between cleaning exposures and respiratory health, in particular asthma, including reviews, epidemiological surveys, surveillance programmes and exposure studies. The authors also aimed to identify gaps in the current knowledge and to recommend future research on the topic. Recent findings A large international general population study showed an increased risk of new-onset asthma associated with cleaning work, with professional use of cleaning products, and with domestic use of cleaning sprays. Three surveillance studies confirm the recognition of occupational asthma cases among cleaners and among others who use cleaning products at work. Six workforce-based studies show that respiratory symptoms are partly work-related, and are associated with certain specific exposures including sprays, chlorine bleach and other disinfectants. Summary Recent studies have strengthened the evidence of asthma and other adverse respiratory effects in cleaning workers. Similar effects were seen in other settings where cleaning products are used such as healthcare professionals and homemakers. Both new-onset asthma and work-exacerbated asthma due to cleaning exposures may play a role. Exposure to cleaning sprays, chlorine bleach and other disinfectants may be particularly relevant. The predominant effect mechanisms remain largely unclear and may include both specific sensitisation and irritant-related features. PMID:20093933

Separate and unsanitary: African American women railroad car cleaners and the Women's Service Section, 1918-1920.

PubMed

Muhammad, Robin Dearmon

2011-01-01

The Women's Service Section (WSS) investigated federally controlled railroad stations and yards at the end of World War I. Few women worked in car cleaning before the war, and railroad management preferred to block women workers, especially African Americans, from gaining any kind of foothold in railroad work. African American women were the single largest group of railroad car cleaners during this period but they were routinely denied adequate facilities, including toilets, locker rooms, and dining facilities throughout the railroad system. By raising the issues of facilities, workers' rights, and public health, these women shaped federal policy and widened the agenda of the WSS to include a direct attack on segregated workplaces. This article argues that African American women car cleaners launched an industrial campaign that wove together concerns about racism, sexism, and health issues, and successfully removed barriers to women working in a predominately male industry.

Cleaning symbioses play an important role in the health of certain coastal marine communities. These interspecific associations often occur at specific sites (cleaning stations) where a cleaner organism (commonly a fish or shrimp) removes ectoparasites/damaged tissue from a 'client' (a larger cooperating fish). At present, the potential impact of climate change on the fitness of cleaner organisms remains unknown. This study investigated the physiological and biochemical responses of tropical (Lysmata amboinensis) and temperate (L. seticaudata) cleaner shrimp to global warming. Specifically, thermal limits (CTMax), metabolic rates, thermal sensitivity, heat shock response (HSR), lipid peroxidation [malondialdehyde (MDA) concentration], lactate levels, antioxidant (GST, SOD and catalase) and digestive enzyme activities (trypsin and alkaline phosphatase) at current and warming (+3 °C) temperature conditions. In contrast to the temperate species, CTMax values decreased significantly from current (24-27 °C) to warming temperature conditions (30 °C) for the tropical shrimp, where metabolic thermal sensitivity was affected and the HSR was significantly reduced. MDA levels in tropical shrimp increased dramatically, indicating extreme cellular lipid peroxidation, which was not observed in the temperate shrimp. Lactate levels, GST and SOD activities were significantly enhanced within the muscle tissue of the tropical species. Digestive enzyme activities in the hepatopancreas of both species were significantly decreased by warmer temperatures. Our data suggest that the tropical cleaner shrimp will be more vulnerable to global warming than the temperate Lysmata seticaudata; the latter evolved in a relatively unstable environment with seasonal thermal variations that may have conferred greater adaptive plasticity. Thus, tropical cleaning symbioses may be challenged at a greater degree by warming-related anthropogenic forcing, with potential cascading effects on the health

'Part of the job': male-to-male sexual experiences and abuse of young men working as 'truck cleaners' along the highways of Pakistan.

2014-01-01

As part of a study on the sexual health and social protection needs of men who have sex with men in Pakistan, 11 young men employed as assistants to truckers ('truck cleaners') who acknowledged having had sexual experiences with men, were interviewed and their social background and sexual initiation and their subsequent sexual lives were explored. For most truck cleaners, the first instance of sexual contact between the truck cleaner and the driver was forced and happened at an early age. Sex with other men, as well as with women (including sex workers) was widely reported. Drug and alcohol use was common. There is strong potential for HIV and STIs to spread through these sexual networks. Measures to prevent young men from entering into a career as truck helpers should be considered, as well as interventions to improve the health and social situation of those already employed.

Study on demetalization of sewage sludge by sequential extraction before liquefaction for the production of cleaner bio-oil and bio-char.

Demetalization of sewage sludge (SS) by sequential extraction before liquefaction was implemented to produce cleaner bio-char and bio-oil. Demetalization steps 1 and 2 did not cause much organic matter loss on SS, and thus the bio-oil and bio-char yields and the compositions of bio-oils were also not affected significantly. However, the demetalization procedures resulted in the production of cleaner bio-chars and bio-oils. The total concentrations and the acid soluble/exchangeable fraction (F1 fraction, the most toxic heavy metal fraction) of heavy metals (Cu, Cr, Pb, Zn, and Cd) in these products were significantly reduced and the environmental risks of these products were also relived considerably compared with those produced from raw SS, respectively. Additionally, these bio-oils had less heavy fractions. Demetalization processes with removal of F1 and F2 fractions of heavy metals would benefit the production of cleaner bio-char and bio-oil by liquefaction of heavy metal abundant biomass like SS.

In the working process of one Beach-Cleaner snatch institution, the second knuckle arm angular speed was too high, which resulted in the pick-up device would crash into the basic arm in the fold process. The rational position of joint to reduce the second knuckle arm angular speed and the force along the axis direction of the most dangerous point can be obtained from the kinematics simulation of snatch institution in the code of Automatic Dynamic Analysis off Mechanical Systems (ADAAMS). The feasible of scheme was validated by analyzing the optimized model in the software of ANSYS. The analysis results revealed: the open angle between the basic arm and the second knuckle arm improved from 125.0° too 135.24°, thee second knuckle arm angular speed decreased from 990.74rad/s to 58.53 rad/s, Not only improved work efficiency of snatch institution, but also prolonged its operation smoothness.

Understanding African American Women’s Decisions to Buy and Eat Dark Green Leafy Vegetables: An Application of the Reasoned Action Approach

Objective Examine intentions to buy and eat dark green leafy vegetables (DGLV). Design Cross-sectional survey assessing demographics, behavior, intention, and Reasoned Action Approach constructs (attitude, perceived norm, self-efficacy). Setting Marion County, Indiana. Participants African American women responsible for buying and preparing household food. Main Outcome Measure(s) Reasoned Action Approach constructs explaining intentions to buy and eat DGLV. Analysis Summary statistics, Pearson correlations, and multiple regression analyses. Results Among participants (n = 410, mean age = 43 y), 76% and 80%, respectively, reported buying and eating DGLV in the past week. Mean consumption was 1.5 cups in the past 3 days. Intentions to buy (r = 0.20, P < .001) and eat (r = 0.23, P < .001) DGLV were positively associated with consumption. Reasoned Action Approach constructs explained 71.2% of the variance in intention to buy, and 60.9% of the variance in intention to eat DGLV. Attitude (β = .63) and self-efficacy (β = .24) related to buying and attitude (β = .60) and self-efficacy (β = .23) related to eating DGLV explained significant amounts of variance in intentions to buy and eat more DGLV. Perceived norm was unrelated to either intention to buy or eat DGLV. Conclusions and Implications Interventions designed for this population of women should aim to improve DGLV-related attitudes and self-efficacy. PMID:24021457

PURPOSE The current model of primary care in the United States limits physicians’ ability to offer high-quality care. The patient-centered medical home (PCMH) shows promise in addressing provision of high-quality care, but achieving a PCMH practice model often requires comprehensive organizational change. Guided by Solberg’s conceptual framework for practice improvement, which argues for shared prioritization of improvement and change, we describe strategies for obtaining organizational buy-in to and whole-staff engagement of PCMH transformation and practice improvement. METHODS Semistructured interviews with 136 individuals and 7 focus groups involving 48 individuals were conducted in 20 small- to mid-sized medical practices in Pennsylvania during the first regional rollout of a statewide PCMH initiative. For this study, we analyzed interview transcripts, monthly narrative reports, and observer notes from site visits to identify discourse pertaining to organizational buy-in and strategies for securing buy-in from personnel. Using a consensual qualitative research approach, data were reduced, synthesized, and managed using qualitative data management and analysis software. RESULTS We identified 13 distinct strategies used to obtain practice buy-in, reflecting 3 overarching lessons that facilitate practice buy-in: (1) effective communication and internal PCMH campaigns, (2) effective resource utilization, and (3) creation of a team environment. CONCLUSION Our study provides a list of strategies useful for facilitating PCMH transformation in primary care. These strategies can be investigated empirically in future research, used to guide medical practices undergoing or considering PCMH transformation, and used to inform health care policy makers. Our study findings also extend Solberg’s conceptual framework for practice improvement to include buy-in as a necessary condition across all elements of the change process. PMID:24445102

Vacuum probe surface sampler

A vacuum probe surface sampler is described for rapidly sampling relatively large surface areas which possess relatively light loading densities of micro-organism, drug particles or the like. A vacuum head with a hollow handle connected to a suitable vacuum source is frictionally attached to a cone assembly terminating in a flared tip adapted to be passed over the surface to be sampled. A fine mesh screen carried by the vacuum head provides support for a membrane filter which collects the microorganisms or other particles. The head assembly is easily removed from the cone assembly without contacting the cone assembly with human hands.

Punishment is an important deterrent against cheating in cooperative interactions. In humans, the severity of cheating affects the strength of punishment which, in turn, affects the punished individual's future behaviour. Here, we show such flexible adjustments for the first time in a non-human species, the cleaner wrasse (Labroides dimidiatus), where males are known to punish female partners. We exposed pairs of cleaners to a model client offering two types of food, preferred ‘prawn’ items and less-preferred ‘flake’ items. Analogous to interactions with real clients, eating a preferred prawn item (‘cheating’) led to model client removal. We varied the extent to which female cheating caused pay-off reduction to the male and measured the corresponding severity of male punishment. Males punished females more severely when females cheated during interactions with high value, rather than low value, model clients; and when females were similar in size to the male. This pattern may arise because, in this protogynous hermaphrodite, cheating by similar-sized females may reduce size differences to the extent that females change sex and become reproductive competitors. In response to more severe punishment from males, females behaved more cooperatively. Our results show that punishment can be adjusted to circumstances and that such subtleties can have an important bearing on the outcome of cooperative interactions. PMID:21676980

Impulsivity is a core feature in patients with traumatic brain injury (TBI). The aim of the study is to investigate how a specific dimension of impulsivity, namely urgency (the tendency to act rashly when distressed), might shed new light on the aetiology of compulsive buying proneness in patients with TBI and to explore how urgency and compulsive buying relate to the burden perceived by the caregivers. Caregivers of 74 patients with TBI were given 3 questionnaires in order to assess their subjective burden as well as patients' impulsivity and compulsive buying proneness. Both urgency and compulsive buying tendencies significantly increased after TBI. Furthermore, path analyses revealed that current urgency was both directly and indirectly related to the subjective burden perceived by the caregivers, and this indirect pathway was mediated by compulsive buying. Urgency plays a central role in understanding specific problematic behaviours after TBI and their impact on caregivers. These findings are discussed in light of the cognitive processes underlying the urgency component of impulsivity in relation to the occurrence of compulsive buying behaviours after TBI.

The objective of the study was to examine the relationship between compulsive buying (CB), depression, materialism, and excessive Internet use. An online survey of 387 consumers was conducted including questions about demographics and shopping venues, the Compulsive Buying Scale, the Patient Health Questionnaire Depression Scale, the Materialistic Values Scale, and questions concerning excessive Internet use. Seventeen percent of the participants reported Compulsive Buying Scale scores less than -1.34 and were considered to be having CB. Participants with CB did not significantly differ from those without CB regarding age, sex, marital status, annual household income, and shopping preferences. Individuals with CB reported more depressive symptoms, higher materialistic values endorsement, and more severe excessive Internet use compared with those without CB. Results of a stepwise logistic regression analysis with CB as the dependent variable showed that materialism and depression were associated with CB, whereas excessive Internet use was not. Materialism and depression jointly influence CB. Further research is needed to examine the influence of materialism on CB in a clinical sample consisting of patients with diagnosed CB.

To compare vacuum rise time, vacuum limit accuracy, and occlusion break surge of 3 new phacoemulsification machines. Jules Stein Eye Institute and Department of Ophthalmology, David Geffen School of Medicine at UCLA, Los Angeles, California, USA. The vacuum rise time under normal and enhanced aspiration modes, vacuum limit accuracy, and occlusion break surge of the Infiniti Vision System, Stellaris Vision Enhancement System, and WhiteStar Signature Phacoemulsification System were tested. Vacuum rise time and limit accuracy were measured at limit settings of 400 mm Hg and 600 mm Hg. Surge area was recorded at vacuum limit settings of 200 mm Hg, 300 mm Hg, 400 mm Hg, and 500 mm Hg. The Infiniti had the fastest vacuum rise times under normal and enhanced aspiration modes. At 4 seconds, the vacuum limit accuracy was greatest with the Infiniti at the 400 mm Hg limit and the Signature at the 600 mm Hg limit. The Stellaris did not reach either vacuum target. The Infiniti performed better than the other 2 machines during testing of occlusion break surge at all vacuum limit settings above 200 mm Hg. Under controlled laboratory test conditions, the Infiniti had the fastest vacuum rise time, greatest vacuum limit accuracy at 400 mm Hg, and least occlusion break surge. These results can be explained by the lower compliance of the Infiniti system.
