摘要： Children display an "essentialist" bias in their everyday thinking about social categories. However, the degree and form of this bias varies with age and with the nature of the categories, as well as across cultures. This project investigated the development of the essentialist bias across five social categories (i.e., gender, nationality, religious affiliation, socioeconomic status (rich/poor), and sports-team supporter) in two countries. Children between 5 and 10 years of age in Turkey (Study 1, N = 74) and the United States (Study 2, N = 73), as well as adults in both countries (Study 3, N = 223), participated. Results indicate surprising cross-cultural parallels with respect to both the rank ordering of essentialist thinking across these five categories and increasing differentiation among them over development.

摘要： Forests are under increasing pressure globally and the establishment of protected areas has long been used as a conservation tool to preserve them. Seven categories of protected areas have been defined by the International Union for Conservation of Nature (IUCN) with different management objectives and protection levels. However, recent studies raised questions over whether protected areas are effective in preventing ecosystem degradation and whether IUCN categories vary in their effectiveness. In this study, we analysed forest loss and trends between 2001 and 2014 within IUCN protected areas at a global scale and within sixteen Intergovernmental Platform for Biodiversity and Ecosystem services (IPBES) subregions, relevant for international policy. As habitat protection can be driven by the location of protected areas and as the amount of forest within protected sites is highly unequal, we reported the forest loss integrating the proximity of roads and population, as well as the amount of initial forest in 2000. Our results show that worldwide, the highest protection categories experienced less forest loss than those allowing more human intervention, although this result was reversed in three IPBES subregions. Moreover, in four subregions there was more forest loss within protected areas than outside. We also found accelerating rates of forest loss in protected areas across all IUCN categories, more pronounced in the highest protection IUCN categories. Our results highlight the importance of moving the discussion of the post-2020 biodiversity framework for protected areas beyond simple general areal targets and that areas with poor implementation effectiveness should benefit from additional support.

摘要： Clustering is a complex unsupervised method used to group most similar observations of a given dataset within the same cluster. To guarantee high efficiency, the clustering process should ensure high accuracy and low complexity. Many clustering methods were developed in various fields depending on the type of application and the data type considered. Categorical clustering considers segmenting a dataset in which the data are categorical and were widely used in many real-world applications. Thus several methods were developed including hard, fuzzy and rough set-based methods. In this survey, more than 30 categorical clustering algorithms were investigated. These methods were classified into hierarchical and partitional clustering methods and classified in terms of their accuracy, precision and recall to identify the most prominent ones. Experimental results show that rough set-based clustering methods provided better efficiency than hard and fuzzy methods. Besides, methods based on the initialization of the centroids also provided good results.

摘要： Purpose To determine the added value of CEUS on arterial phase non-hyperenhancement (APNHE) observations (LR-3 and LR-4) of CT/MRI in high-risk patients. Methods Forty-three patients with APNHE observations (>= 2 cm) from CT/MRI were prospectively enrolled in this IRB-approved study and underwent CEUS. All observations were assessed by LI-RADS for CT/MRI and CEUS. The hemodynamic findings were compared. The mean follow-up period was 11.8 +/- 2.1 months. Reference standard was made on 34-APNHE observations based on biopsy (n = 2), surgery (n = 2), and follow-up image (n = 30). Results The median of observation size was 2.3 cm (IQR 2.0-2.5 cm). Among the 43-APNHE observations, 12-observations (27.9%) were further presented as arterial phase hyperenhancement (APHE) in CEUS with early (n = 1, CEUS LR-M), late (n = 10, CEUS LR-5), or no (n = 1, CEUS LR-4) washout. Compared to CT, CEUS presented concordant enhancement patterns in 16 (44.4%) in AP and 20 (55.6%) in PVP, respectively. Similarly, 13 (59.1%) and 14 (63.6%) observations showed concordant enhancement patterns between CEUS and MRI in AP and PVP, respectively. Of the 34-APNHE observations with final diagnosis (hepatocellular carcinoma [HCC] n = 12;intrahepatic cholangiocarcinoma [IHCC], n = 1;non-malignancy, n = 21), 4 HCCs (33.3%) and 1 IHCC (100%) were additionally diagnosed by CEUS, while 1 non-malignant lesion (4.5%) was misdiagnosed as HCC by CEUS. Conclusion Adding CEUS to APNHE observations from CT/MRI would be useful not only for definitely diagnosing HCC (CEUS LR-5) but also for other malignancies ( CEUS LR-M). The discordance of dynamic features between the LI-RADS for CEUS and CT/MRI may reflect the different properties of contrast media, although the systems are not interchangeable.

关键词： Epistemic modality   Alignment   Stance   Intersubjectivity   Japanese conversation   Interactional linguistics  

摘要： The present study investigates the locally situated interactional functions of so-called epistemic modals, daroo and deshoo, in Japanese conversation. Although the two forms are generally considered plain and polite variants of the same epistemic modal, both forms frequently appear in the present casual conversational data. A detailed sequential analysis demonstrates that daroo and deshoo are used to perform various social actions rather than simply expressing the speaker's conjecture. Deshoo has a rather fixed function of soliciting alignment or confirmation from the interlocutor. On the other hand, daroo works as part of larger constructions for various actions, including (i) displaying spontaneity, (ii) expressing neutral or uninvolved stance, (iii) displaying alignment, (iv) qualifying one's assertion, and (v) challenging the interlocutor's assertion. The findings suggest that linguistic categories such as 'epistemic modals' are epiphenomena of social interaction (Ford et al., 2013), which are not themselves interactionally relevant to the conversational participants.

关键词： Inflation expectations   Experimental forecasts   Survey forecasts   Market-based forecasts   Central bank forecasts  

摘要： Establishing the external validity of experimental inflation forecasts is essential if laboratory experiments are to be used as decision-making tools for monetary policy. Our contribution is to document whether different measures of inflation expectations, based on various categories of agents (participants in experiments, households, industry forecasters, professional forecasters, financial market participants and central bankers), share common patterns. We do so by analyzing the forecasting performance of these different categories of data, their deviations from full information rational expectations, and the variables that enter the determination of these expectations. Overall, the different categories of forecasts exhibit common features: forecast errors are comparably large and autocorrelated, and forecast errors and forecast revisions are predictable from past information, suggesting the presence of some form of bounded rationality or information imperfections. Finally, lagged inflation positively affects the determination of inflation expectations. While experimental forecasts are relatively comparable to survey and financial market data, more heterogeneity is observed compared to central bank forecasts. (C) 2019 Elsevier B.V.

摘要： Large volumes of contaminated water are produced via intentional and unintentional incidents, including terrorist attacks, natural disasters and accidental spills. Contaminated waters could contain harmful chemicals, which present management and disposal challenges. This study investigates three Advanced Oxidation Processes (AOPs) - UV/H2O2, O-3/H2O2, and electrochemical oxidation using a borondoped diamond (BDD) anode - to treat eleven contaminants including herbicides, pesticides, pharmaceuticals, and flame retardant compounds. To address treatment and toxicity concerns, this study focuses on the resulting microbial toxicity via Microtox (R) toxicity and Nitrification Inhibition tests. The results suggest four functional Microtox (R) toxicity categories upon AOP treatment, which are useful for streamlining AOP selection for specific applications. Except for one compound, the O-3/H2O2 and UV/H2O2 AOPs achieved, within experimental error, 100% parent compound degradation during 2 h of treatment for all contaminants, as well as Microtox (R) toxicities that declined below 10% by the end of the treatment. In addition, anodic oxidation with a BDD electrode exhibited slower degradation and some increases in Microtox (R) toxicity. Only one compound exhibited above 50% Nitrification Inhibition, indicating the robustness of activated sludge to many contaminated and AOP-treated waters. These results indicate that AOP pre-treatment can be a viable strategy to facilitate drain disposal of contaminated waters, but that eco-toxicity may remain a concern. Published by Elsevier Ltd.

关键词： Decamethylcyclopentasiloxane   Environmental emissions   Exposure assessment   Probabilistic model   Risk management  

摘要： Aquatic risk assessment of personal care chemicals requires quantifying the contribution of all product types containing these ingredients to down-the-drain emissions. We developed a probabilistic model framework embracing stochastic variability associated with individual consumers and their behaviors in the European Union, as well as other sources of uncertainty related to losses following applications (e.g., volatilization). The model was applied to decamethylcyclopentasoloxane (D5), an emollient used in wash-off (WO) and leave-on (LO) products. Quantifying contributions from each product category containing D5 to down-the-drain emissions is necessary to inform optimal risk management options. Simulation results for the baseline scenario in 2012 support the argument that LO products make up a minor contribution (7.1%) to down-the-drain emissions of D5, with only 0.20% of the D5 used in LO products being released to wastewater. The most influential model parameters are the release factor from WO products and the time between application and use for various LO product types, stressing the importance of embracing stochastic variability across individuals' behavior when assessing contributions of various product types to environmental emissions. The downward trend in WO use from 2010 to 2016 is reflected in declining concentrations in wastewater influent during the same period. Uncertainty remains about future levels of D5, once phasing out WO products is complete. The probabilistic model in conjunction with high-tier data of consumer habits is a promising high-tier tool for the characterization of complex emission scenarios of personal care ingredients.

摘要： Background/objectives To examine the association of body mass index (BMI) with change in children's physical activity and sedentary time between ages 6 and 11. Participants A total of 2132 children participated from 57 schools in Southwest England, from the B-PROACT1V study. Methods Mean minutes of MVPA and sedentary time per day were derived from accelerometer-based measurements at ages 6, 9 and 11. Linear multilevel models examined the association of BMI categories with MVPA and sedentary time between 6 and 11, adjusting for seasonality, wear time, gender and household education. Differences in change over time were examined using interaction terms. Results Average weekday MVPA decreased between ages 6 and 11 by 2.2 min/day/year (95% CI: 1.9 to 2.5), with a steeper decline at weekends. Average sedentary time increased at a rate of 12.9 min/day/year (95% CI: 12.2 to 13.6). There were no differences in mean levels of MVPA by BMI categories at age 6, but differences emerged as children aged, with the gap between children who were healthy weight and overweight increasing by 1.7 min/day (95% CI: 0.8-2.6) every year, and between healthy and obese by 2.0 min/day (95% CI: 0.9-3.1) each year. Children who were overweight/obese engaged in less average weekday sedentary time at age 6 than those of healthy weight, but the gap closed by age 11. Conclusion MVPA declines and sedentary time increases on average for all children between ages 6 and 11. While there are no differences in activity levels by BMI category at age 6, differences in MVPA emerge over time for those who are overweight and obese. Developing interventions that support children to retain activity levels as they approach older childhood, particularly those who are overweight/obese could improve public health.

关键词： behavioral economics   categorical cognition   hybrid organizations   impact investing   social enterprise  

摘要： Research Summary The emerging practice of "impact investing" optimizes both financial and social outcomes, and thus promises to support hybrid organizations that simultaneously pursue financial and social goals. We argue, however, that impact investing decisions may be prone to behavioral factors that limit their outcome efficiency. In a portfolio allocation task designed to reflect the essential features of an impact investing decision, we find across a range of scenarios that individuals systematically fail to choose investment portfolios that achieve financial and social outcomes efficiently and thereby waste opportunities for value creation. We further show in online and in-person experiments that outcome inefficiency is related to "categorical cognition": suppression of categorical labels on investment options increases efficiency. Managerial Summary The "impact investing" approach promises to encourage greater financial investments in hybrid organizations that pursue a combination of financial and social goals. We experimentally demonstrate a challenge of this approach: People struggle to identify portfolios of investments that simultaneously optimize across financial and social outcomes. This is partly due to "categorical cognition": a natural tendency to view investments in terms of known categories rather than the actual outcomes they produce. Our experiments show that removing the labels "for-profit company," "charity," and "social enterprise" from investment options-thus making it more difficult to think about them categorically-increases outcome-efficient allocations. We therefore show that realizing the full potential of impact investing will require that investors transcend conventional thinking about business and charity as separate domains.
