Distress tolerance represents the capacity to bear and manage negative psychological states associated with distress. Low distress tolerance is a transdiagnostic construct implicated in many psychopathological conditions. The Distress Tolerance Scale (DTS) is a 15-item self-report instrument specifically designed to assess this construct. The aim of this study was to investigate the psychometric properties of the Italian version of the DTS. Factor structure, internal consistency, temporal stability, and construct validity were investigated in 477 participants from the general population. Exploratory and confirmatory factor analyses supported the one-factor structure of the DTS. The scale also showed good internal consistency, temporal stability, and construct validity. These findings suggest that the Italian version of the DTS retains the adequate psychometric properties of the original and suggest that it can be confidently used as an assessment tool of distress tolerance in both clinical and research settings.
A series of Mo-doped LiFe1−3x Mo x PO4/C (x =0.000, 0.025, 0.050, 0.100, 0.150) cathode materials are synthesized by sol–gel method. XRD, ICP and Rietveld refinement results reveal that Mo doped in the crystal lattice and probably occupied Fe site. The structure benefits the transportation of Li+ and the diffusion of Li+ in the doped materials are enhanced remarkably than that of the undoped one, which leads to excellent electrochemical performance. The doped sample with x =0.025 exhibits the best electrochemical performance, with the initial discharge capacity of 162.3mAhg−1 at 0.1C rate.
Monitoring the dynamic chemical and thermal state of a cell during operation is crucial to making meaningful advancements in battery technology as safety and reliability cannot be compromised. Here we demonstrate the feasibility of incorporating optical fibre Bragg grating sensors into commercial 18650 cells. By adjusting fibre morphologies, wavelength changes associated with both temperature and pressure are decoupled with high accuracy, which allows tracking of chemical events such as solid electrolyte interphase formation and structural evolution. We also demonstrate how multiple sensors are used to determine the heat generated by the cell without resorting to microcalorimetry. Unlike with conventional isothermal calorimetry, the cell’s heat capacity contribution is readily assessed, allowing for full parametrization of the thermal model. Collectively, these findings offer a scalable solution for screening electrolyte additives, rapidly identifying the best formation processes of commercial cells and designing battery thermal management systems with enhanced safety.
The interaction of patients with their doctors impacts the experience of disease at many levels. It is thus important to measure patient satisfaction with such interaction as an outcome of care. Our goal was to investigate whether tumor status influences patient satisfaction with interaction with their doctors. Specifically, we investigated whether patients with no evidence of disease (NED), localized, or metastatic cancers seen in routine follow-up differ in their satisfaction with the oncologist. Outpatients attending clinics at a major cancer center completed a battery of questionnaires, including the Patient Satisfaction with Doctor (PSQ-MD) questionnaire, a 24-item, self-report instrument. It taps two facets of the doctor-patient exchange: perceived support and physician disengagement. Data concerning tumor status and satisfaction were obtained for 569 patients, sampled to include equivalent numbers of women and men with breast, head and neck, gastrointestinal, genitourinary, or lung cancer, or lymphoma. Controlling for age, marital status, annual family income, stressful life events, and employment status, patients with metastatic disease felt somewhat less supported by their physicians (mean=3.26±0.06) than those with localized disease (mean=3.42±0.04) or NED (mean=3.42±0.03), (analysis of covariance, p< 0.05). Physician disengagement did not differ across the groups (means=1.54±0.06, 1.43±0.04, and 1.47±0.03 respectively). These findings were consistent across cancer diagnoses. Patients with metastatic disease may feel less physician support than those with less advanced cancers. Increasing attention to satisfaction of different patient groups can pave the way to improved quality of care.
SnO thick-film electrodes for Na-ion battery anodes were prepared for the first time by a gas-deposition method, and we investigated the influence of fluoroethylene carbonate as an electrolyte additive on their anode performances. The SnO electrode showed high reversible capacities of 580 mA h g−1 and 260 mA h g−1 at the first cycle and at the 20th cycle, respectively, in an additive-free electrolyte. The cycle performance obtained was much higher than that of an Sn electrode. These results indicate that Na2O formed in the first Na-insertion process played a role as a matrix to alleviate a stress generated by drastic volumetric changes during alloying/dealloying reactions of Sn with Na. When we used fluorothylene carbonate as an additive, the SnO electrode achieved 250 mA h g−1 at the 50th cycle with a good capacity retention. The excellent cycle performance originates from a facile Na-ion transfer through a surface layer formed between the electrode and the electrolyte because the surface layer derived from additive prevents from making itself thicker by suppressing decomposition of the electrolyte.
Factor analytic studies of attention-deficit/hyperactivity disorder (ADHD) in children and adults have shown that second-order and bifactor models better represent ADHD symptoms than two- or three-factor models, yet there is far less evidence for a bestfitting model of ADHD in adolescence. Thus, the current study examined the factor structure of ADHD in adolescence and further evaluated the external validity of the best fitting model. Participants were 588 adolescents (22 % female; 366 with a childhood ADHD diagnosis; mean age 15.9 years) from the 8-year assessment of the Multimodal Treatment Study of Children with ADHD (MTA). ADHD symptoms were assessed via adolescent self-report, parent report, and teacher report on the SNAP-IV scale. Potential factor structures for the 18 symptoms of ADHD were tested for each informant, which included traditional one-factor, two-factor, and three-factor models of ADHD, as well as second-order factor (specific factors loading onto general factor) and bifactor (items loading onto both specific and general factors) models. Unique associations between external criteria and the identified factors of each informant’s best fitting model were examined. Although several of the proposed models exhibited good fit, the second-order two-factor model best accounted for ADHD in adolescence according to self-report and parent report, and the second-order three-factor model was optimal according to teacher report. Several key measurement issues emerged for the hierarchical bifactor models, such as numerous Heywood cases and out-of-bound parameter estimates, which rendered them unfit as optimal representations of ADHD in adolescence. These findings and the implications of the best fitting model of ADHD in adolescence suggest that a possible reorganization of this disorder may eventually aid clinicians in the accurate diagnosis of ADHD in adolescents.
Three-dimensional transient thermal analyses of an air-cooled module that contains prismatic lithium-ion cells operating under an aggressive driving profile were performed using a commercial computational fluid dynamics code. The existing module utilized air cooling through evenly-spaced channels on both sides of each cell. It was found that lowering the gap spacing and/or higher flow rate of the fan lead to a decrease of the maximum temperature rise. To achieve improved temperature uniformity over the module, the gap spacing should be of a moderate size. For the given module, operating with a uniform gap spacing of 3 mm and an air flow rate of 40.8 m3 h−1 appears to be the best choice that satisfies the trade-off requirements of the fan power, maximum temperature rise and temperature uniformity. Using the same gap spacing and air flow rate, a proposed design of one-side cooling is less effective than two-side cooling. Uneven gap spacing affects the temperature distributions, but it does not impact the maximum temperature rise markedly. Considering the variety of the design change options and their combinations, it is concluded that the temperature gradients along the air flow direction can be affected but are generally unavoidable.
Animals need sufficient space to ensure physical health and to permit the performance of important behaviors. The effects of spatial restriction will increase with duration of confinement. In addition, diurnal rhythms are relevant. Animals may often require only sufficient space to rest comfortably but, at certain periods, additional space will be required for the performance of comfort, foraging, social or exploratory behavior. The spatial needs of unassuming animals such as chickens and rodents have been assessed using many approaches. First, animals can be housed at relevant allowances and a broad range of measures of health, behavior, physiological status and immune function taken to assess overall welfare. Second, the behavior of animals can be observed after spatial restriction is removed. A significant rebound in behavior performance would indicate that this behavior was being prevented by confinement. Third, the strength of animals' choices for additional space can be examined. Evidence from all three approaches showed that the extreme spatial confinement experienced by laying hens in conventional battery cages resulted in poor welfare, helping to secure a phase-out of conventional cages in Europe by 2012. It has been more difficult to establish optimum space allowances for species kept under less extreme restriction, such as laboratory mice and rats. No consistent effects on welfare were found when inbred and outbred mice were housed at 60, 100 or 167 cm2/mouse. In contrast, sleep disruption was increased when young rats housed were housed at higher stocking densities. Finally, assessment of optimum spatial allowance (stocking density) for animals housed in large groups, is complicated by complex interactions between enclosure size and group number.
This paper presents a prognostic study on lithium-ion batteries in implantable medical devices, in which a hybrid data-driven/model-based method is employed for remaining useful life assessment. The method is developed on and evaluated against data from two sets of lithium-ion prismatic cells used in implantable applications exhibiting distinct fade performance: 1) eight cells from Medtronic, PLC whose rates of capacity fade appear to be stable and gradually decrease over a 10-year test duration; and 2) eight cells from Manufacturer X whose rates appear to be greater and show sharp increase after some period over a 1.8-year test duration. The hybrid method enables online prediction of remaining useful life for predictive maintenance/control. It consists of two modules: 1) a sparse Bayesian learning module (data-driven) for inferring capacity from charge-related features; and 2) a recursive Bayesian filtering module (model-based) for updating empirical capacity fade models and predicting remaining useful life. A generic particle filter is adopted to implement recursive Bayesian filtering for the cells from the first set, whose capacity fade behavior can be represented by a single fade model; a multiple model particle filter with fixed-lag smoothing is proposed for the cells from the second data set, whose capacity fade behavior switches between multiple fade models.
Sandplay and storytelling are therapeutic techniques that are used to elicit significant themes in clients’ social-emotional lives, and social constructivism is an appropriate theoretical framework with which to conceptualize the process of play therapy [Dale, M. A., & Lyddon, W. J. (2000). Sandplay: A constructivist strategy for assessment and change. Journal of Constructivist Psychology, 13, 135–154; Russo, in press]. The purpose of this study was to use the combined sandplay-storytelling technique to explore counselors’ understanding of the manner in which children's interpersonal relationships and developmental status are reflected in their reconstruction of their social worlds in the sandtray. This qualitative study focused on the language of play as expressed in the context of young clients’ cognitive developmental levels via sandplay-storytelling techniques. Six counselors participated in the study and worked with child and adolescent clients. Case analyses conducted by the counselors revealed themes that were consistent with clients’ cognitive developmental status according to Piagetian developmental stages. Younger children, 5–8 years of age, showed a transition from preoperational to concrete operational thought, whereas adolescents, 12–18 years of age, operated from a concrete to abstract orientation. In addition, counselors observed the stages of sandplay as outlined by Allan and Berry [Allan, J., & Berry, P. (1993). Sandplay. In C.E. Schaefer & D.M. Cangelosi (Eds.). Play therapy techniques (pp. 117–123). Northvale, NJ: Jason Aronson Inc.) in that clients were able to develop resolution to their stories by repositioning figures to a more adaptive stance.
Continuous-flow technologies are becoming increasingly relevant in the chemistry field. The vast arrays of reactor design, in terms of structural geometry, mixing, and residence time, the modularity of these systems, adaptable for every application, and the easy downstream integrations are at the basis for their success. Over the past decade, the value and potential of flow technologies became apparent, particularly for drug discovery and drug development. However, other areas of research, which include the circular valorization of waste products and the manufacturing of materials and catalysts, have been less touched by the revolution that miniaturization brings in terms of efficiency, safety, environmental impact, and processability. This review critically evaluates the emerging use of flow technologies in these areas, highlighting recent advances, current challenges, and future directions in the quest for leaner and cleaner processing methods.
This paper discusses solar power prospects in Wilayat Duqum in Oman. First, the geographic and topographic information about the selected region is presented. The methodology of producing solar radiation map for Duqum using GIS tools is then presented. The results obtained show very high potential of solar radiation over Wilayat Duqum during the whole year. A slope analysis has allowed calculating the yearly electricity generation potential for different concentrated solar power (CSP) technologies such as the parabolic trough, parabolic dish, tower, and concentrated PV. Based on the development plan of the Duqum region, and the topologies of the land areas in the region, it is suggested that, for the CSP technologies requiring large amount of water for washing the mirrors, the selected area is a flat land (slope<1%) located proximity to the sea (∼2km) inside a total industrial area of around 50km2, hence, allowing easy future expansion of the plant. It was proposed to start with a 100MW power plant which is expected to consume about 2.4km2 of flat land for the parabolic trough CSP technology. The total calculated potential of yearly electricity generation would be about 2.3TWh. If half of the selected land (0.5×50km2) is reserved for future expansion of the plant, the total future capacity can attain 1GW of electric power. The selected area can also accommodate in the future different types of CSP technologies as they mature with time.
Glutamatergic N-methyl-d-aspartate (NMDA) receptor hypofunction has been proposed as a mechanism underlying psychosis. d-cycloserine, a partial agonist at the glycine site of the NMDA receptor, enhances learning in animal models, although tachyphylaxis develops with repeated dosing. Once-weekly dosing of d-cycloserine produces persistent improvement when combined with cognitive behavioral therapy (CBT) in anxiety disorders. Delusional beliefs can be conceptualized as a learning deficit, characterized by the failure to use contradictory evidence to modify the belief. CBT techniques have been developed with modest success to facilitate such reality-testing (or new learning) in delusional beliefs. The current study evaluated whether d-cycloserine could potentiate beneficial effects of CBT on delusional severity. Twenty-one outpatients with schizophrenia or schizoaffective disorder and moderately severe delusions were randomized in a double-blind cross-over design to receive a single-dose of either d-cycloserine 50mg or placebo in a counterbalanced order on two consecutive weeks 1h prior to a CBT intervention involving training in the generation of alternative beliefs. Assessments were completed at baseline, 7days following the first study drug administration and 7days following the second study drug administration. Contrary to prediction, there was no significant d-cycloserine treatment effect on delusional distress or severity as measured by the SAPS or PSYRATS. An unexpected finding was an order effect, whereby subjects who received d-cycloserine first had significantly reduced delusional severity, distress, and belief conviction on PSYRATS compared to subjects who received placebo first. However, this finding is consistent with animal models in which d-cycloserine enhances learning only when accompanying the first exposure to training.
Commercial lithium-ion (Li-ion) batteries built with Ni- and Co-based intercalation-type cathodes suffer from low specific energy, high toxicity and high cost. A further increase in the energy storage characteristics of such cells is challenging because capacities of such intercalation compounds approach their theoretical values and a further increase in their maximum voltage induces serious safety concerns. The growing market for portable energy storage is undergoing a rapid expansion as new applications demand lighter, smaller, safer and lower cost batteries to enable broader use of plug-in hybrid and pure-electric vehicles (PHEVs and EVs), drones and renewable energy sources, such as solar and wind. Conversion-type cathode materials are some of the key candidates for the next-generation of rechargeable Li and Li-ion batteries. Continuous rapid progress in performance improvements of such cathodes is essential to utilize them in future applications. In this review we consider price, abundance and safety of the elements in the periodic table for their use in conversion cathodes. We further compare specific and volumetric capacities of a broad range of conversion materials. By offering a model for practically achievable volumetric energy density and specific energy of Li cells with graphite, silicon (Si) and lithium (Li) anodes, we observe the impact of cathode chemistry directly. This allows us to estimate potentials of different conversion cathodes for exceeding the energy characteristics of cells built with state of the art intercalation compounds. We additionally review the key challenges faced when using conversion-type active materials in cells and general strategies to overcome them. Finally, we discuss future trends and perspectives for cost reduction and performance enhancement.
The neural underpinnings of human emotional expression are thought to be unevenly distributed among the two brain hemispheres. However, little is known on the anatomy supporting this claim, particularly in the cerebral white matter. Here, we explored the relationship between hemi-face dominance in emotional expression and cerebral white matter asymmetries in 33 healthy participants. Measures of emotional expression were derived from pictures of the participant’s faces in a ‘happy smiling’ and a ‘sad frowning’ conditions. Chimeric faces were constructed by mirroring right and left hemi-faces, as done in previous studies, resulting in a left mirrored and right mirrored chimeric face per picture. To gain measures of hemi-face dominance per participant, a jury of 20 additional participants rated which chimeric face shows the higher intensity of emotional expressivity, by marking a 155 mm line between the two versions. Measures of the asymmetry of the uncinate, the cingulum and the three branches of superior longitudinal fasciculi were derived from diffusion-weighted imaging tractography dissections. Group effect analyses indicated that the degree of asymmetry in emotional expression was not as prominent as reported in the literature and showed a large inter-individual variability. The degree of asymmetry in emotional expression was, however, significantly associated with the asymmetries in connective properties of the fronto-temporal and fronto-parietal tracts, specifically the uncinate fasciculus and the first branch of the superior longitudinal fasciculus. Therefore, this result raises novel hypotheses on the relationship of specific white matter tracts and emotional expression, especially their role in mood disorders.
A series of Li1.2Mn0.6-x/2Ni0.2-x/2FexO2 (x=0, 0.03, 0.06, 0.10) cathode materials has been prepared by a modified Pechini process. The structure and morphology of the obtained materials have been examined by X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) techniques. The electrochemical properties of Li1.2Mn0.6-x/2Ni0.2-x/2FexO2 have been characterized systematically and Li1.2Mn0.585Ni0.185Fe0.03O2 exhibits the best cyclic stability and high-rate capability. The Li1.2Mn0.585Ni0.185Fe0.03O2 electrode delivers a large reversible discharge capacity of 261.6 mAh g−1 at 0.1C-rate with a high capacity retention rate of 90.9% after 80 cycles. Meanwhile it displays obviously improved rate capability with the capacity of 187.3 mAh g−1 at the 1C-rate and stable cycling performance of 165 mAh g−1 after 150 cycles. The effects of a small amount of Fe doping are explored through ex-situ XRD, X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscope (HRTEM), differential capacity vs. voltage (dQ/dV) plots and electrochemical impedance spectroscopy (EIS). The results show stable layered structure and well-crystallized particle surface for Li1.2Mn0.585Ni0.185Fe0.03O2 electrode in contrast with spinel nanodonmains distribution and amorphous surface region for Li1.2Mn0.6Ni0.2O2 electrode upon cycling, which account for the outstanding electrochemical performance of Fe doped Li1.2Mn0.6Ni0.2O2 cathode material.
A large-scale potentially traumatic event (PTE) poses considerable mental health risks for police services. There is limited literature detailing the mental health outcomes following large-scale PTEs. This study examined the mental health outcomes amongst Queensland Police Service (QPS) staff following a large-scale PTE. Two hundred and sixteen Australian police officers and support staff involved in the response to a natural disaster completed a clinical interview and measures of psychological distress (Kessler 10) and post-traumatic stress (PCL-C) 4 weeks post-deployment to the incident. The results showed that approximately 24% of the participants had elevated levels of general distress, while 13% had clinical levels of PTSD symptoms. Age was associated with the severity of PTSD symptoms but not general distress. Civilian staff reported significantly higher symptoms of general distress and PTSD than police officers. Females reported significantly higher symptoms of psychological distress than males; however, no differences were observed for symptoms of post-traumatic stress. Finally, the K10 had strong convergent validity with clinical levels of PTSD as measured by the PCL-C indicating that the K10 may be a useful general screening measure of both general distress and PTSD symptoms when brevity is needed in a large-scale PTE mental health screening measure.
