Thinking like Disney: Supporting the Disney method using ambient feedback based on group performance

The Disney method is a collaborative creativity technique that uses three roles - dreamer, realist and critic - to facilitate the consideration of different perspectives on a topic. Especially for novices it is important to obtain guidance in applying this method. One way is providing groups with a trained moderator. However, feedback about the group’s behavior might interrupt the flow of the idea finding process. We built and evaluated a system that provides ambient feedback to a group about the distribution of their statements among the three roles. Our preliminary field study indicates that groups supported by the system contribute more and roles are used in a more balanced way while the visualization does not disrupt the group work.

The association between ambient temperature and children's lung function in Baotou, China

The objective of this study is to examine the association between ambient temperature and children’s lung function in Baotou, China. We recruited 315 children (8–12 years) from Baotou, China in the spring of 2004, 2005, and 2006. They performed three successive forced expiratory measurements three times daily (morning, noon, and evening) for about 5 weeks. The highest peak expiratory flow (PEF) was recorded for each session. Daily data on ambient temperature, relative humidity, and air pollution were monitored during the same period. Mixed models with a distributed lag structure were used to examine the effects of temperature on lung function while adjusting for individual characteristics and environmental factors. Low temperatures were significantly associated with decreases in PEF. The effects lasted for lag 0–2 days. For all participants, the cumulative effect estimates (lag 0–2 days) were −1.44 (−1.93, −0.94) L/min, −1.39 (−1.92, −0.86) L/min, −1.40 (−1.97, −0.82) L/min, and −1.28 (−1.69, −0.88) L/min for morning, noon, evening, and daily mean PEF, respectively, associated with 1 °C decrease in daily mean temperature. Generally, the effects of temperature were slightly stronger in boys than in girls for noon, evening, and daily mean PEF, while the effects were stronger in girls for morning PEF. PM2.5 had joint effects with temperature on children’s PEF. Higher PM2.5 increased the impacts of low temperature. Low ambient temperatures are associated with lower lung function in children in Baotou, China. Preventive health policies will be required for protecting children from the cold weather.

Au-Pd alloy nanoparticle catalyzed selective oxidation of benzyl alcohol and tandem synthesis of imines at ambient conditions

Alloy nanoparticles (NPs) of gold and palladium on ZrO2 support (Au–Pd@ZrO2) were found to be highly active in oxidation of benzyl alcohols and can be used for the tandem synthesis of imines from benzyl alcohols and amines via a one-pot, two-step process at mild reaction conditions. The first step of the process is oxidation of benzyl alcohol to benzaldehyde, excellent yields were achieved after 7 h reaction at 40 °C without addition of any base. In the second step, aniline was introduced into the reaction system to produced N-benzylideneaniline. The benzaldehyde obtained in the first step was completely consumed within 1 h. A range of benzyl alcohols and amines were investigated for the general applicability of the Au–Pd alloy catalysts. It is found that the performance of the catalysts depends on the Au–Pd metal contents and composition. The optimal catalyst is 3.0 wt% Au–Pd@ZrO2 with a Au:Pd molar ratio 1:1. The alloy NP catalyst exhibited superior catalytic properties to pure AuNP or PdNP because the surface of alloy NPs has higher charge heterogeneity than that of pure metal NPs according to simulation of density function theory (DFT)

Global variation in the effects of ambient temperature on mortality: A systematic evaluation

Background: Studies have examined the effects of temperature on mortality in a single city, country, or region. However, less evidence is available on the variation in the associations between temperature and mortality in multiple countries, analyzed simultaneously. Methods: We obtained daily data on temperature and mortality in 306 communities from 12 countries/regions (Australia, Brazil, Thailand, China, Taiwan, Korea, Japan, Italy, Spain, United Kingdom, United States, and Canada). Two-stage analyses were used to assess the nonlinear and delayed relation between temperature and mortality. In the first stage, a Poisson regression allowing overdispersion with distributed lag nonlinear model was used to estimate the community-specific temperature-mortality relation. In the second stage, a multivariate meta-analysis was used to pool the nonlinear and delayed effects of ambient temperature at the national level, in each country. Results: The temperatures associated with the lowest mortality were around the 75th percentile of temperature in all the countries/regions, ranging from 66th (Taiwan) to 80th (UK) percentiles. The estimated effects of cold and hot temperatures on mortality varied by community and country. Meta-analysis results show that both cold and hot temperatures increased the risk of mortality in all the countries/regions. Cold effects were delayed and lasted for many days, whereas heat effects appeared quickly and did not last long. Conclusions: People have some ability to adapt to their local climate type, but both cold and hot temperatures are still associated with increased risk of mortality. Public health strategies to alleviate the impact of ambient temperatures are important, in particular in the context of climate change.

The effects of ambient temperature on cerebrovascular mortality: An epidemiologic study in four climatic zones in China

Background Little evidence is available about the association between temperature and cerebrovascular mortality in China. This study aims to examine the effects of ambient temperature on cerebrovascular mortality in different climatic zones in China. Method We obtained daily data on weather conditions, air pollution and cerebrovascular deaths from five cities (Beijing, Tianjin, Shanghai, Wuhan, and Guangzhou) in China during 2004-2008. We examined city-specific associations between ambient temperature and the cerebrovascular mortality, while adjusting for season, long-term trends, day of the week, relative humidity and air pollution. We examined cold effects using a 1°C decrease in temperature below a city-specific threshold, and hot effects using a 1°C increase in temperature above a city-specific threshold. We used a meta-analysis to summarize the cold and hot effects across the five cities. Results Beijing and Tianjin (with low mean temperature) had lower thresholds than Shanghai, Wuhan and Guangzhou (with high mean temperature). In Beijing, Tianjin, Wuhan and Guangzhou cold effects were delayed, while in Shanghai there was no or short induction. Hot effects were acute in all five cities. The cold effects lasted longer than hot effects. The hot effects were followed by mortality displacement. The pooled relative risk associated with a 1°C decrease in temperature below thresholds (cold effect) was 1.037 (95% confidence interval (CI): 1.020, 1.053). The pooled relative risk associated with a 1°C increase in temperature above thresholds (hot effect) was 1.014 (95% CI: 0.979, 1.050). Conclusion Cold temperatures are significantly associated with cerebrovascular mortality in China, while hot effect is not significant. People in colder climate cities were sensitive to hot temperatures, while people in warmer climate cities were vulnerable to cold temperature.

An analytical study revisiting debate on interpretation of Article 38 of the Statute of International Court of Justice

Article 38(1) of the Statute of International Court of Justice (hereinafter ICJ) is today generally seen as a direction to the significant sources of international law, which the world court must consider in resolving disputes; however, the list is not exhaustive nor encompasses all the formal and material sources of the international legal system. Article 38 of the Statute of ICJ was written ninety years ago in a different world, a question is under debate in many states, whether or not sources mentioned in Article 38 of the statute are compatible with needs of 21st century ? In recent decade, many new actors come on the stage which have transformed international law and now it is not only governs relations among states but also covers many International Organizations. Article 38(2) does refer to the other possible sources but does not define them. Moreover, law is a set of rules that citizens must follow to regulate peace and order in society. These laws are binding on both the individual and the state on a domestic and international level. Do states regard this particular rule as a rule of international law? The modern legal system of states is in the form of a specified and well organized set of rules, regulating affairs of different organs of a state. States also need a body of rules for their intercourse with each other. These sets of rules among states are called “International Law.” This article examines international law, its foundation and sources. It considers whether international conventions and treaties can be the only way states can considerably create international law, or there is a need for clarity about the sources of international law. Article is divided into two parts, the first one deals with sources of international law discussed in Article 38 of the statute of International Court of Justice whereas the second one discusses the material and formal sources of law, which still need reorganization as sources of law.

Assessing environmental inequalities in ambient air pollution across urban Australia

Identifying inequalities in air pollution levels across population groups can help address environmental justice concerns. We were interested in assessing these inequalities across major urban areas in Australia. We used a land-use regression model to predict ambient nitrogen dioxide (NO2) levels and sought the best socio-economic and population predictor variables. We used a generalised least squares model that accounted for spatial correlation in NO2 levels to examine the associations between the variables. We found that the best model included the index of economic resources (IER) score as a non-linear variable and the percentage of non-Indigenous persons as a linear variable. NO2 levels decreased with increasing IER scores (higher scores indicate less disadvantage) in almost all major urban areas, and NO2 also decreased slightly as the percentage of non-Indigenous persons increased. However, the magnitude of differences in NO2 levels was small and may not translate into substantive differences in health.

Buoyant Jet Discharges into Finite Ambient Waters

The paper presents the results of an experimental study regarding the effect of the lateral dimension of the receiving water on the spreading, mixing, and temperature decay of a horizontal buoyant surface jet. The widths of the ambient water in the experiments have been 240, 120, 90 and 60 times the diameter of the jet nozzle. Based on the experimental data, correlations are carried out and empirical equations for prediction of jet width, thickness in vertical direction and longitudinal temperature decay are obtained. The available data of earlier investigators are included to obtain generalized equations for the spreading and temperature decay. Similarity of temperature profiles in the lateral and vertical directions is observed. The longitudinal temperature decay is found to vary inversely with distance in the flow direction and ¼th power of the densimetric Froude number.

Long-term ambient air pollution exposure and self-reported morbidity in the Australian Longitudinal Study on Women's Health: A cross-sectional study

- Objective We sought to assess the effect of long-term exposure to ambient air pollution on the prevalence of self-reported health outcomes in Australian women. - Design Cross-sectional study - Setting and participants The geocoded residential addresses of 26 991 women across 3 age cohorts in the Australian Longitudinal Study on Women's Health between 2006 and 2011 were linked to nitrogen dioxide (NO2) exposure estimates from a land-use regression model. Annual average NO2 concentrations and residential proximity to roads were used as proxies of exposure to ambient air pollution. - Outcome measures Self-reported disease presence for diabetes mellitus, heart disease, hypertension, stroke, asthma, chronic obstructive pulmonary disease and self-reported symptoms of allergies, breathing difficulties, chest pain and palpitations. - Methods Disease prevalence was modelled by population-averaged Poisson regression models estimated by generalised estimating equations. Associations between symptoms and ambient air pollution were modelled by multilevel mixed logistic regression. Spatial clustering was accounted for at the postcode level. - Results No associations were observed between any of the outcome and exposure variables considered at the 1% significance level after adjusting for known risk factors and confounders. - Conclusions Long-term exposure to ambient air pollution was not associated with self-reported disease prevalence in Australian women. The observed results may have been due to exposure and outcome misclassification, lack of power to detect weak associations or an actual absence of associations with self-reported outcomes at the relatively low annual average air pollution exposure levels across Australia.

Quantitative assessment of total and Gram-positive aerobic bacteria in fresh and ambient-temperature-stored sub-tropical marine fish

The current study was undertaken to enumerate Gram-positive bacteria in fresh sub-tropical marine fish and determine the effect of ambient storage (25°C) on the Gram-positive bacterial count. Total and Gram-positive bacteria were enumerated in the muscles, gills and gut of fresh and stored Pseudocaranx dentex, Pagrus auratus and Mugil cephalus on tryptone soya agar (TSA) and TSA with 0.25% phenylethyl alcohol (PEA), respectively. Initial studies indicated that PEA significantly reduced total aerobic bacterial count (TABC) whereas control Gram-positive bacteria were not affected by 0.25% PEA. TABC significantly increased in all fish body parts, whereas Gram-positive aerobic bacterial count (GABC) significantly increased only in the muscles and gills during ambient storage for 15 h. The TABC of the fish species increased from 4.00, 6.13 and 4.58 log cfu g-1, respectively in the muscles, gills, and gut to 6.31, 7.31 and 7.23 log cfu g-1 by the end of storage. GABC increased from 2.00, 3.52 and 2.20 log cfu g-1 to 4.70, 5.85 and 3.36 log cfu g-1. Within each species, TABC were significantly higher in the gills compared to that of muscles and gut; however, no significant differences were found in GABC between muscles and gills. This study demonstrated the potential importance of Gram-positive bacteria in sub-tropical marine fish and their spoilage.

"America Would Lose Its Soul" : The Immigration Restriction Debate, 1920-1924

Vuosien 1830 ja 1924 välillä Yhdysvaltoihin muutti noin 35 miljoonaa eurooppalaista. Tämä niinkutsuttu "maahanmuuton vuosisata" päättyi varsin äkillisesti kun Yhdysvallat päätti rajoittaa maahanmuuttoa 1920-luvulla. Vuosina 1921 ja 1924 säädetyt lait asettivat kansallisuuteen perustuvat kiintiöt kaikille eurooppalaisille maahanmuuttajille; vuoden 1924 laki myös lopetti kokonaan japanilaisten maahanmuuton. Tämä työ tutkii näihin kiintiölakeihin johtanutta maahanmuuttajavastaisuuden kasvua sekä etenkin lakien ympärillä käytyä keskustelua. Pääpaino on kongressissa esitetyissä maahanmuuton vastaisissa argumenteissa. Nämä jakautuivat karkeasti ottaen kolmeen kategoriaan: maahanmuuton vastustajat sanoivat, että siirtolaisten vaikutus taloudelliseen tilanteeseen oli epäsuotuisa, siirtolaisten rodullinen ja kulttuurinen "laatu" oli huonontunut, ja siirtolaiset olivat radikaaleja ja bolshevismiin taipuvaisia. Erityistä huolta herätti maahanmuuttajien vaikutus Amerikan kulttuuriseen, rodulliseen ja poliittiseen yhtenäisyyteen. Huoli kansakunnan yhtenäisyydestä oli tulosta paitsi siirtolaisten määrästä myös amerikkalaisessa yhteiskunnassa tapahtuneista muutoksista. Erityisen tärkeitä olivat työväenliikkeen vaikutusvallan kasvu ja teollisuusjohtajien pyrkimys pysäyttää se. Maahanmuuttajien "bolshevismi" olikin käyttökelpoinen argumentti paitsi maahanmuuttajia myös amerikkalaisia työläisiä vastaan: teollisuusjohtajat painottivat että lakot ja työväenliike olivat tulosta siirtolaisten mukanaan tuomista "epäamerikkalaisista" ajatusmalleista, eivät yhteiskunnan epäoikeudenmukaisuudesta. Kongressin keskustelun lisäksi työssä käsitellään myös eri yhteiskunnallisten ryhmien ja vaikuttajien kantaa siirtolaisuuteen. Keskusteluun maahanmuutosta vaikuttivat etenkin eugenistit ja muut sosiaalitieteilijät, jotka väittivät itä- ja eteläeurooppalaisten olevan rodullisesti anglosakseja huonompia. Tämän väitteen vaikutusvaltaa lisäsivät yhteiskunnassa vallalla olleet ennakkoluulot, ja monet yhdistykset ja liikkeet (mm. Ku Klux Klan ja erilaiset isänmaalliset järjestöt) olivatkin tärkeitä rajoittamisen kannattajia. Keskustelu maahanmuutosta painottui ideologisiin ja tunteellisiin kysymyksiin, mutta rajoitusten taustalla oli myös konkreettisempia tekijöitä. Yhteiskunnan teollistuminen ja kaupungistuminen olivat pienentäneet siirtolaisista koituvaa taloudellista hyötyä: siirtolaisia ei enää tarvittu raivaamaan uusia viljelysmaita, kun taas tuotannon koneistuminen vähensi työvoiman tarvetta huomattavasti. Pitkän aikavälin taloudellisten tekijöiden roolin merkitys käy ilmeiseksi kun otetaan huomioon, että muut maahanmuuttomaat (esim. Kanada ja Australia) eivät juuri rajoittaneet siirtolaisuutta tänä aikana vaikka niissäkin esiintyi runsaasti rodullista ja kulttuurista maahanmuuttajavastaisuutta. Pääsyy rajoitusten vähäisyyteen näissä maissa oli juuri maahanmuuttajien tuoma taloudellinen hyöty, sekä teollisena työvoimana että maanviljelijöinä. Vaikka kiintiölakiehdotusten ympärillä käytiin kiivasta väittelyä, kongressi kuitenkin hyväksyi lait varsin suurella enemmistöllä. Siirtolaisia itseään lukuunottamatta varsin harvat näkivät lait haitallisina, kun taas useat erilaiset ryhmät katsoivat hyötyvänsä maahanmuuton rajoittamisesta. Avainsanat: siirtolaisuus, maahanmuutto, Yhdysvallat, 1920-luku, kiintiölait, maahanmuuton rajoittaminen

Private governance of public rights in Japan: Revisiting the Japanese governance debate

Dramatic growth in the Japanese economy in the postwar period – and its meltdown in the 1990s – has attracted sustained interest in the power dynamics underlying the management of Japan’s administrative state. For a long time, scholars and commentators have debated about who wields power in Japan. The question has been asked in different ways. In the 1970s and 1980s, the question was usually posed as: who orchestrated Japan’s economic miracle in the 1960s and 1970s? Today, the question is usually reframed to: who is accountable for the policy failures that plunged Japan into financial crisis and recession during the 1990s? Yet the core issue remains the same – who governs Japan? (Johnson 1995)...

The big pond debate.

Over recent decades, Australian piggeries have commonly employed anaerobic ponds to treat effluent to a standard suitable for recycling for shed flushing purposes and for irrigation onto nearby agricultural land. Anaerobic ponds are generally sized according to the Rational Design Standard (RDS) developed by Barth (1985), resulting in large ponds, which can be expensive to construct, occupy large land areas, and are difficult and expensive to desludge, potentially disrupting the whole piggery operation. Limited anecdotal and scientific evidence suggests that anaerobic ponds that are undersized according to the RDS, operate satisfactorily, without excessive odour emission, impaired biological function or high rates of solids accumulation. Based on these observations, this paper questions the validity of rigidly applying the principles of the RDS and presents a number of alternate design approaches resulting in smaller, more highly loaded ponds that are easier and cheaper to construct and manage. Based on limited data of pond odour emission, it is suggested that higher pond loading rates may reduce overall odour emission by decreasing the pond volume and surface area. Other management options that could be implemented to reduce pond volumes include permeable pond covers, various solids separation methods, and bio-digesters with impermeable covers, used in conjunction with biofilters and/or systems designed for biogas recovery. To ensure that new effluent management options are accepted by regulatory authorities, it is important for researchers to address both industry and regulator concerns and uncertainties regarding new technology, and to demonstrate, beyond reasonable doubt, that new technologies do not increase the risk of adverse impacts on the environment or community amenity. Further development of raw research outcomes to produce relatively simple, practical guidelines and implementation tools also increases the potential for acceptance and implementation of new technology by regulators and industry.

Speciation of Gram-positive bacteria in fresh and ambient-stored sub-tropical marine fish.

This study identified Gram-positive bacteria in three sub-tropical marine fish species: Pseudocaranx dentex (silver trevally), Pagrus auratus (snapper) and Mugil cephalus (sea mullet). It further elucidated the role played by fish habitat, fish body part and ambient storage on the composition of the Gram-positive bacteria. A total of 266 isolates of Gram-positive bacteria were identified by conventional biochemical methods, VITEK, PCR using genus- and species-specific primers and/or 16S rRNA gene sequencing. The isolates were found to fall into 13 genera and 30 species. In fresh fish, Staphylococcus epidermidis and Micrococcus luteus were the most frequent isolates. After ambient storage, S. epidermidis, S. xylosus and Bacillus megaterium were no longer present whereas S. warned, B. sphaericus, Brevibacillus borstelensis, Enterococcus faecium and Streptococcus uberis increased in frequency. Micrococcus luteus and S. warned were the most prevalent isolates from P. dentex, while E. faecium and Strep. uberis were the most frequent isolates from P. auratus and M. cephalus. With respect to different parts of the fish body. E. faecium, Strep. uberis and B. sphaericus were the most frequent isolates from the muscles, E. faecium, Strep. uberis from the gills and M. luteus from the gut. This study showed a diversity of Gram-positive bacteria in sub-tropical marine fish; however, their abundance was affected by fish habitat, fish body part and ambient storage.
