The brain's interpretation of sound is influenced by cues from other senses, explaining more precisely how we interpret what we hear at a particular moment, according to a report published in Nature Neuroscience online Oct. 31. In the new study in mice, researchers at NYU Langone Medical Center found that nerve cells dedicated to hearing also rely on surrounding context to properly interpret and react to familiar sounds. "What the brain 'hears' depends on what is 'seen' in addition to specific sounds, as the brain calculates how to respond," says study senior investigator and neuroscientist Robert Froemke, PhD, an assistant professor at NYU Langone and its Skirball Institute of Biomolecular Medicine. Froemke says his team's latest findings reveal that while mammals recognize sounds in the auditory cortex of their brains, the signaling levels of nerve cells in this brain region are simultaneously being strengthened or weakened in response to surrounding context. "Our study shows how the same sound can mean different things inside the brain depending on the situation," says Froemke. "We know, for instance, that people learn to respond without alarm to the honk of a car horn if heard from the safety of their homes, but are startled to hear the same honk while crossing a busy street." If further experiments find similar activity in human brains, the researchers say their work may lead to precise explanations of situation-specific behaviors, such as anxiety brought on during math exams; sudden post-traumatic stress among combat veterans hearing a car backfire; and the ability of people with dementia to better remember certain events when they hear a familiar voice or see a friend's face. To map how the same sense can be perceived differently in the brain, the NYU Langone team, led by postdoctoral fellow Kishore Kuchibhotla, PhD, monitored nerve circuit activity in mice when the animals expected, and did not expect, to get a water reward through a straw-like tube (that they see) after the ringing of a familiar musical note. When mice were exposed to specific auditory cues, researchers observed patterns based on a basic divide in the nature of nerve cells. Each nerve cell "decides" whether a message travels onward in a nerve pathway. Nerve cells that emit chemicals which tell the next cell in line to amplify a message are excitatory; those that stop messages are inhibitory. Combinations of the two strike a counterbalance critical to the function of the nervous system, with inhibitory cells sculpting "noise" from excitatory cells into the arrangements behind thought and memory. Furthermore, the processing of incoming sensory information is achieved in part by adjusting signaling levels through each type of nerve cell. Theories hold that the brain may attach more importance to a given signal by turning up or down excitatory signals, or by doing the same with inhibitory nerve cells. In the current study, researchers found to their surprise that most of the nerve cells in auditory cortex neurons that stimulate brain activity (excitatory) had signaled less (had "weaker" activity) when the mice expected and got a reward. Meanwhile, and to the contrary, a second set of remaining "excitatory" neurons saw greater signaling activity when mice expected a reward based on exposure to the two sensory cues and got one. Further tests showed that the activation of specific inhibitory neurons -- parvalbumin, somatostatin, and vasointestinal peptide -- was responsible for these changes and was in turn controlled by the chemical messenger, or neurotransmitter, acetylcholine. Chemically shutting down acetylcholine activity cut in half the number of times mice successfully went after their water reward when prompted by a ring tone. Some studies in humans have linked acetylcholine depletion to higher rates of Alzheimer's disease. Froemke, who is also a faculty scholar at the Howard Hughes Medical Institute, says the team next plans to assess how the hormones noradrenaline and dopamine affect auditory cortex neurons under different situations. "If we can sort out the many interactions between these chemicals and brain activity based on sensory perception and context, then we can possibly target specific excitatory and inhibitory neurological pathways to rebalance and influence behaviors," says Froemke. Funding support for the study was provided by National Institute on Deafness and Other Communication Disorders grants R01 DC009635, R01 DC012557, and R01 DC05014; National Institute of Development Administration grant T32 DA007254; a Sloan Research Fellowship; a Klingenstein Fellowship; and the Charles H. Revson Senior Fellowship in Biomedical Sciences. In addition to Froemke and Kuchibhotla, other NYU Langone researchers involved in the study are Jonathan Gill, MS; Grace Lindsay, BS; Eleni Papadoyannis; Rachel Field, BS; and Tom Hindmarsh Sten. Additional research support was provided by Kenneth Miller, PhD, at Columbia University, also in New York City.

Objective To explore the positive and negative effects of medical tourism on the economy, health staff and medical costs in Thailand. Methods The financial repercussions of medical tourism were estimated from commerce ministry data, with modifications and extrapolations. Survey data on 4755 foreign and Thai outpatients in two private hospitals were used to explore how medical tourism affects human resources. Trends in the relative prices of caesarean section, ppendectomy, hernia repair, cholecystectomy and knee replacement in five private hospitals were examined. Focus groups and in-depth interviews with hospital managers and key informants from the public and private sectors were conducted to better understand stakeholders' motivations and practices in connection with these procedures and learn more about medical tourism. Findings Medical tourism generates the equivalent of 0.4% of Thailand's gross domestic product but has exacerbated the shortage of medical staff by luring more workers away from the private and public sectors towards hospitals catering to foreigners. This has raised costs in private hospitals substantially and is likely to raise them in public hospitals and in the universal health-care insurance covering most Thais as well. The "brain drain" may also undermine medical training in future. Conclusion Medical tourism in Thailand, despite some benefits, has negative effects that could be mitigated by lifting the restrictions on the importation of qualified foreign physicians and by taxing tourists who visit the country solely for the purpose of seeking medical treatment. The revenue thus generated could then be used to train physicians and retain medical school professors.

Vertical variations of polycyclic aromatic hydrocarbon (PAH) concentrations in PM10 were investigated in order to assess the factors controlling their behavior in the urban atmosphere of Bangkok City, Thailand. Air samples were collected every three hours for three days at three different levels at Bai-Yok Suit Hotel (site-1 and site-2) and Bai-Yok Sky Hotel (site-3) in February 18th-21st, 2008. The B[a]P concentration showed a value 0.54 fold, lower than the United Kingdom Expert Panel on Air Quality Standard (UK-EPAQS; i.e. 250 pg m-3) at the top level. In contrast, the B[a]P concentrations exhibited, at the ground and middle level, values 1.50 and 1.43 times higher than the UK-EPAQS standard respectively. PAHs displayed a diurnal variation with maximums at night time because of the traffic rush hour coupled with lower nocturnal mixing layer, and the decreased wind speed, which consequently stabilized nocturnal boundary layer and thus enhanced the PAH contents around midnight. By applying Nielsen's technique, the estimated traffic contributions at Site-3 were higher than those of Site-1: about 10% and 22% for Method 1 and Method 2 respectively. These results reflect the more complicated emission sources of PAHs at ground level in comparison with those of higher altitudes. The average values of incremental individual lifetime cancer risk (ILCR) for all sampling sites fell within the range of 10-7-10-6, being close to the acceptable risk level (10-6) but much lower than the priority risk level (10-4).

Diurnal variation of particulate polycyclic aromatic hydrocarbons (PAHs) was investigated by collecting PM10 at three different sampling altitudes using high buildings in the city center of Chiang-Mai, Thailand, during the relatively cold period in late February 2008. At site-1 (12 m above ground level), B[a]P concentrations ranged from 30.3 -1,673 pg m-3 with an average of 506±477 pg m-3, contributing on average, 8.09±8.69% to ΣPAHs. Ind and B[b]F concentrations varied from 54.6 to 4,579 pg m-3 and from 80.7 to 2,292 pg m-3 with the highest average of 1,187±1,058 pg m-3 and 963±656 pg m-3, contributing on average, 19.0±19.3% and 15.4±12.0% to ΣPAHs, respectively. Morning maxima were predominantly detected in all observatory sites, which can be described by typical diurnal variations of traffic flow in Chiang-Mai City, showing a morning peak between 6 AM. and 9 AM. Despite the fact that most monitoring sites might be subjected to specific-site impacts, it could be seen that PAH profiles in Site-1 and Site-2 were astonishingly homogeneous. The lack of differences suggests that the source signatures of several PAHs become less distinct possibly due to the impacts of traffic and cooking emissions from ground level.

It is well known that increased incidences of lung, skin, and bladder cancers are associated with occupational exposure to PAHs. Animal studies show that certain PAHs also can affect the hematopoietic and immune systems and can produce reproductive, neurologic, and developmental effects. As a consequence, several studies have been attempted to investigate the fate of PAHs in atmospheric environment during the past decades. However, there is still a lack of information in regard to the atmospheric concentration of PAHs during the "Bon Fire Night". In this study, twenty-three polycyclic aromatic hydrocarbons and twenty-eight aliphatics were identified and quantified in the PM10 and vapour range in Birmingham (27th November 2001-19th January 2004). The measured concentrations of total particulate and vapour (P+V) PAHs were consistently higher at the BROS in both winter and summer. Arithmetic mean total (P+V) PAH concentrations were 51.04±47.62 ng m-3 and 22.30±19.18 ng m-3 at the Bristol Road Observatory Site (BROS) and Elms Road Observatory Site (EROS) respectively. In addition arithmetic mean total (P+V) B[a]P concentrations at the BROS were 0.47±0.39 ng m-3 which exceeded the EPAQS air quality standard of 0.25 ng m-3. On the other hand, the arithmetic mean total (P+V) aliphatics were 81.80±69.58 ng m-3 and 48.00±35.38 ng m-3 at the BROS and EROS in that order. The lowest average of CPI and Cmax measured at the BROS supports the idea of traffic emissions being a principle source of SVOCs in an urban atmosphere. The annual trend of PAHs was investigated by using an independent t-test and oneway independent ANOVA analysis. Generally, there is no evidence of a significant decline of heavier MW PAHs from the two data sets, with only Ac, Fl, Ph, An, 2-MePh, 1+9-MePh, Fluo and B[b+j+k]F showing a statistically significant decline (p<0.05). A further attempt for statistical analysis had been conducted by dividing the data set into three groups (i.e. 2000, 2001-2002 and 2003-2004). For lighter MW compounds a significant level of decline was observed by using one-way independent ANOVA analysis. Since the annual mean of O3 measured in Birmingham City Centre from 2001 to 2004 increased significantly (p<0.05), it may be possible to attribute the annul reduction of more volatile PAHs to the enhanced level of annual average O3. By contrast, the heavier MW PAHs measured at the BROS did not show any significant annual reduction, implying the difficulties of 5-and 6-ring PAHs to be subject to photochemical decomposition. The deviation of SVOCs profile measured at the EROS was visually confirmed during the "Bonfire Night" festival closest to the 6th November 2003. In this study, the atmospheric PAH concentrations were generally elevated on this day with concentrations of Fl, Ac, B[a]A, B[b+j+k]F, Ind and B[g, h, i]P being particularly high.

The objective of this work was to study the nutrient removal using the Wolffia arrhiza during the treatment of laying quails farm effluent. The relationship between W. arrhiza biomass and treatment time, the change in water qualities, and nitrogen-balance (N-balance) were evaluated. The results showed that a biomass of 12.0. g of W. arrhiza per liter of effluent and a treatment period of 30. days were found to provide the best conditions for W. arrhiza's growth and the quality of the treated effluent in terms of biological oxygen demand, suspended solids, total phosphorus, nitrate, total ammonia nitrogen and total Kjeldahl nitrogen. The pH and salinity were similar for each level of biomass. The W. arrhiza biomasses of 4.00-12.0. g/l of effluent were suitable for W. arrhiza survival over time. Since W. arrhiza can fix N in the atmosphere, it can grow very well in effluent containing a low level of N. © 2011 Elsevier Ltd.

Studies related to the use of social media in the workplace are still somewhat scarce despite their increasing popularity in social media research. This paper aims to investigate how employee perceptions of a workplace related to coworker support, supervisor support, and job-related demands can determine the degree of attachment some employees feel to social media use at work. The study also explores some consequences of social media use at work by analyzing its associations with job satisfaction, job performance, and cognitive absorption. The data was collected through the snowball sampling technique of 170 employees in Thailand and analyzed using partial least squares regression. For the factors predicted to influence social media use at work, the analysis found that coworker support and job demands are positively associated with social media use intensity, while supervisor support is negatively associated with it. The analysis also found a positive association between job satisfaction and job performance and social media use at work. An indirect relationship between social media use and cognitive absorption was also found through the mediating effect of job satisfaction. Overall, the evidence suggests that social media use at work may not necessarily lead to negative job-related outcomes. © 2014 Elsevier Ltd. All rights reserved.

According to Buddhist teachings, giving without condition leads to a higher level of happiness. Even though there are a number of studies examining factors that determine happiness, none quantitatively examine happiness from the perspective of a “giving” relationship. Using a household dataset from Thailand, where Buddhism is the main religion, this paper suggests that religious and nonreligious giving leads to a higher happiness level than not giving at all. Moreover, for nonreligious giving, it is found that charitable giving in terms of money and goods gives a donor more happiness than does volunteer work, but that both types of giving enhance one’s happiness. Religious giving (offering food and dedicating other offerings to Buddhist monks) is also found to increase happiness, more so for respondents who regularly give for religious purposes. In particular, regularly giving to monks leads to the highest happiness level, perhaps since Buddhism permeates Thai society and dedicating offerings to monks is believed to provide great merit. In addition, when making offerings to monks, donors usually do it randomly, at a temple, which suggests that making merit at a temple also leads to higher level of happiness. © 2014, Springer Science+Business Media Dordrecht and The International Society for Quality-of-Life Studies (ISQOLS).

Polycyclic Aromatic Hydrocarbons (PAHs) are a class of very stable organic molecules made up of only carbon and hydrogen and contain two to eight fused aromatic rings. PAHs are formed during incomplete combustion of organic materials such as fossil fuels, coke and wood. PAHs can be found in environment, the atmosphere, surface water, sediment, soil, food and in lipid tissues of both aquatic and terrestrial organisms. Natural emission sources of PAHs into the atmosphere include emissions from forest fires and volcanoes. Anthropogenic emission sources include combustion and industrial production. Incomplete combustion from motor vehicles, domestic heating and forest fires are major sources of PAHs in the atmosphere. Assuming that each region has different types of PAH emission sources, it seems rationale to hypothesize that the fingerprint of PAHs in agricultural products has its own unique locality characteristic. Since the food traceability is extremely crucial for food business, one can use PAH profile extracts from agricultural products to identify the originality. Three groups of soybean were classified according to the planting areas. In conclusion, soybean from three different countries (i.e. Thailand, Taiwan, Indonesia) can successfully be identified with the assistance of ANOVA and three-dimensional plots of binary diagnostic ratios of PAHs. © 2014 Elsevier Ltd.

Queuing analysis is mostly used for creating service design and resource allocation plan in many service organisations. In such turbulent business environment, the service organisations are required responding to the changing demand and supply circumstances by adjusting the resources more frequently. Thus, flexibility performance should be evaluated in more constructive manners for service improvement. Due to its multi-dimensional performance, the evaluation requires an integrated framework incorporating a conventional method, i.e., queuing analysis, and analytical approaches. This paper presents how flexibility performance in banking services can be determined by using queuing theory and also provides insights on the limitation of measures, i.e., resource utilisation and customer waiting time used in the queuing model to cope with other flexibility dimensions. Consequently, the integrated framework is proposed for service organisation striving for meeting the highest customer service level. Copyright © 2012 Inderscience Enterprises Ltd.
