Superradiance and exciton delocalization in bacterial photosynthetic light-harvesting systems.
LH-2 complexes of Rhodobacter sphaeroides and on the isolated B820 subunit of Rhodospirillum rubrum. From these measurements the superradiance is calculated, which is related to the delocalization of excitations in these complexes. In the B820 preparation we find a radiative rate that is 30 % higher than that of monomeric bacteriochlorophyll, in agreement with a dimer model of this subunit. At room temperature both LH-1 and LH-2 are superradiant relative to monomeric Bchl-a with enhancement factors of 3.8 and 2.8, respectively. In LH-2 the radiative rate does not change significantly upon lowering the temperature to 4 K. LH-1 however exhibits a strong temperature dependence, giving rise to a 2.4 times higher radiative rate at 4 K relative to room temperature. From modeling of the superradiance using a Hamiltonian based on the LH-2 structure and including site inhomogeneity, we conclude that the ratio of inhomogeneity over the coupling betwee
Substance use by adolescents in special education and residential youth care institutions
This study examined substance use rates and related background factors among adolescents in special education (SE) and in residential youth care institutions (RYC). Information on substance use from 531 adolescents in RYC, 603 adolescents in SE for students with behavioral problems (SEB) and 1,905 adolescents in SE for students with learning disabilities (SEL) was compared with information from 7,041 adolescents who attended mainstream education. Results show that substance use rates are particularly high among adolescents in RYC and in SEB. For example, 22% of the 12–13 years old in RYC and 16% in SEB was a daily smoker compared with 1% of their counterparts in mainstream education. Background factors, including age, ethnic background and family situation, partly explained the differences in substance use between mainstream education on the one hand and SE and RYC on the other hand, but differences between the groups remained substantial and significant. Several interaction effects were found in the relation between SE/RYC and substance use that were all in line with the risk paradox: some subgroups that are normally at lower risk for problem behavior are at higher risk when they are subjected to high-risk indicators. The elevated risk of substance use among adolescents in RYC/SE was in some cases particularly marked for those who would normally be at lower risk for substance use (girls in SEB for heavy alcohol drinking and cannabis use, ethnic minority adolescents and adolescents with a stable family situation in RYC for respectively heavy weekly alcohol drinking and daily use of tobacco). Results of this study have important implications for health education and intervention programs for adolescents in RYC and SE

Adolescents who attend special education for behavioural problems (SEB) and adolescents who live in a residential youth care institution (RYC) are characterised by behavioural disorders and problematic family backgrounds and have an increased risk for substance use. Though it is likely that the high rates of substance use in SEB/RYC settings might be inherent to the risk profile of these adolescents, little is known about the actual role the risk profile has in explaining substance use. The present study examined the extent to which the elevated risk of substance use in SEB/RYC can be explained by high levels of individual, family, and peer risk indicators that are known to characterise their risk profile. Self-report questionnaires from 531 adolescents in RYC (50 % male; mean age 14.7) and 603 adolescents in SEB (81 % male; mean age 14.1) were compared with information from 1,905 adolescents attending special education for students with learning disabilities (SEL) (56 % male; mean age 14.1). Results show that adolescents in SEB/RYC reported higher levels of daily smoking, weekly alcohol consumption, cannabis and hard drug use, as well as greater prevalence of individual, family and peer factors. Though individual, family and in particular peer risk indicators all explain some of the variance in substance use, the differences between adolescents in SEB/RYC compared with SEL remained significant and substantial, with the exception of heavy alcohol consumption. These findings suggest that deviant peer affiliation, in particular, plays a role in explaining high substance use levels in SEB/RYC and those factors relevant to the residential settings and special education schools might also contribute to substance use in these high-risk groups
Context Effects of Alcohol Availability at Home: Implicit Alcohol Associations and the Prediction of Adolescents' Drinking Behavior
OBJECTIVE: Recent studies suggest that the predictive effect of implicit alcohol associations is context dependent. Findings indicate that implicit associations are more easily retrieved in an alcohol-associated setting or context (e.g., bar) compared with a neutral setting. In line with this reasoning, we hypothesized that alcohol availability at home might moderate the relationship between implicit alcohol associations and future drinking behavior of adolescents. METHOD: Participants were 262 at-risk adolescents (235 boys, 27 girls, adolescents with externalizing behavioral problems) with a mean age of 14.11 years (SD = 0.86, age range: 12-16 years) at baseline. Adolescents completed a questionnaire and a modified version of the Implicit Association Test (i.e., Single Category Implicit Association Test; SC-IAT). RESULTS: Stronger implicit alcohol associations predicted increase in frequency of alcohol use, only in adolescents who indicated that alcohol was available at home. No moderating effects were found for increase in quantity of alcohol use and problematic alcohol use, suggesting that implicit alcohol associations particularly influence the decision of whether to drink in adolescence. CONCLUSIONS: The findings illustrate that the availability of alcohol in the home setting influences adolescents' implicit alcohol associations and consequently affects the frequency of alcohol use. In this way, alcohol availability at home may be an important contextual factor to consider when examining the effect of implicit alcohol associations on the future drinking behavior of adolescents
Social Acceptance of Smoking Restrictions During 10 Years of Policy Implementation, Reversal, and Reenactment in the Netherlands:Findings From a National Population Survey
Introduction: Little is known about the extent to which smoking restrictions are socially accepted in a country such as the Netherlands where smoking restrictions have been implemented and reversed several times. The current study assessed trends as well as factors associated with two indicators of social acceptance of smoking restrictions in the Netherlands: acceptance of smoking in public places and implementation of home smoking bans. Methods: We used data from the Dutch Continuous Survey of Smoking Habits (DCSSH) between 2005 and 2014 (n = 182 826). The DCSSH is a national population survey with a cross-sectional design in which respondents aged 15 years and older are surveyed weekly. Results: Acceptance of smoking in public places decreased for six out of eight included venues, with the largest decrease for smoking in restaurants. The decrease in acceptance was larger among younger respondents and smokers. Smoking on terraces was an exception: decrease in acceptance there was larger among older respondents and ex-smokers. Implementation of home smoking bans increased over time. Having implemented a home smoking ban was associated with being male, being younger, having a high socioeconomic status, and being ex-or never smoker. Conclusions: Social acceptance of smoking restrictions has increased in the Netherlands, despite a suboptimal implementation process of smoking restrictions. However, there is still potential for improvement as acceptance of smoking is still quite high for some public venues like bars. It is important to strengthen smoking restrictions in order to further denormalize smoking in the Netherlands. Implications: We examined the extent to which smoking restrictions are socially accepted in the Netherlands where smoking restrictions have been implemented and reversed several times. Acceptance of smoking in public places decreased and implementation of home smoking bans increased between 2005 and 2014. Social acceptance of smoking restrictions increased in the Netherlands despite a suboptimal implementation process of smoking restrictions. However, acceptance of smoking in bars remains relatively high
Architecture for the Reengineering of Legacy Point of Sale Terminals through Web Services for the Reduction of Transaction Fees
With the conventional legacy POS payment transaction method, vendors are bound to a payment institute in their region and can only use relatively expensive dedicated
or slow dial-up lines to their financial institute. This chapter covers the work to produce an architecture that shows how to reengineer traditional point of sales terminal payments in order to adapt these for payment over the Internet through Web services
The utility of HepG2 cells to identify direct mitochondrial dysfunction in the absence of cell death.
Drug-induced mitochondrial dysfunction has been hypothesized to be an important determining factor in the onset of drug-induced liver injury. It is essential to develop robust screens with which to identify drug-induced mitochondrial toxicity and to dissect its role in hepatotoxicity. In this study we have characterised a mechanistically refined HepG2 model, using a panel of selected hepatotoxicants and non-hepatotoxicants. We have demonstrated that acute metabolic modification, via glucose-deprivation over a 4 h period immediately prior to compound addition, is sufficient to allow the identification of drugs which induce mitochondrial dysfunction, in the absence of cell death over a short exposure (2 – 8 h) using a plate-based screen to measure cellular ATP content and cytotoxicity. These effects were verified by measuring changes in cellular respiration, via oxygen consumption and extracellular acidification rates. Overall, these studies demonstrate the utility of HepG2 cells for the identification of mitochondrial toxins which act directly on the electron transport chain and that the dual assessment of ATP content alongside cytotoxicity provides an enhanced mechanistic understanding of the causes of toxicity
