Alcohol-selling outlets and mortality in Switzerland--the Swiss National Cohort

AIM To examine the association of alcohol-related mortality and other causes of death with neighbourhood density of alcohol-selling outlets for on-site consumption. DESIGN, SETTING AND PARTICIPANTS Longitudinal study of the adult Swiss population (n = 4 376 873) based on census records linked to mortality data from 2001 to 2008. MEASUREMENTS Sex-specific hazard ratios (HR) for death and 95% confidence intervals (95%CI) were calculated using Cox models adjusting for age, educational level, occupational attainment, marital status and other potential confounders. The density of alcohol-selling outlets within 1000 m of the residence was calculated using geocodes of outlets and residences. FINDINGS Compared with >17 outlets within 1000 m the HR for alcohol-related mortality in men was 0.95 (95%CI: 0.89-1.02) for 8-17 outlets, 0.84 (95%CI: 0.77-0.90) for 3-7 outlets, 0.76 (95%CI: 0.68-0.83) for 1-2 outlets and 0.60 (95%CI: 0.51-0.72) for 0 outlets. The gradient in women was somewhat steeper, with a HR comparing 0 with >17 outlets of 0.39 (95%CI: 0.26-0.60). Mortality from mental and behavioural causes and lung cancer were also associated with density of alcohol-selling outlets: HRs comparing 0 outlets with >17 outlets were 0.64 (95%CI: 0.52-0.79) and 0.79 (95%CI: 0.72-0.88), respectively, in men and 0.46 (95%CI: 0.27-0.78) and 0.63 (95%CI: 0.52-0.77), respectively, in women. There were weak associations in the same direction with all-cause mortality in men but not in women. CONCLUSIONS In Switzerland, alcohol-related mortality is associated with the density of outlets around the place of residence. Community-level interventions to reduce alcohol outlet density may usefully complement existing interventions.

The influence of formal and informal sales controls on customer-directed selling behaviors and sales unit effectiveness

Adaptive selling (AS) and customer-oriented selling (COS) constitute two key customer-directed selling behaviors for the success of the modern sales force. However, knowledge regarding the organizational factors that can induce salespeople to engage in those behaviors is strikingly limited. Against this background, we develop a comprehensive model that delineates the influences of formal and informal sales controls on AS and COS and, through them, on sales unit effectiveness. Based on a sample of sales managers in a major European Union country, we present new evidence that (a) formal and informal sales controls exert differential impact on salespeople's AS and COS behaviors; (b) AS directly and positively influences sales unit effectiveness; (c) COS affects sales unit effectiveness only indirectly, i.e. by fostering AS; and (d) outcome and cultural controls directly improve sales unit effectiveness. We conclude with a discussion of our findings for academics and practitioners.

Electrostatic sampling of trace DNA from clothing.

During acts of physical aggression, offenders frequently come into contact with clothes of the victim, thereby leaving traces of DNA-bearing biological material on the garments. Since tape-lifting and swabbing, the currently established methods for non-destructive trace DNA sampling from clothing, both have their shortcomings in collection efficiency and handling, we thought about a new collection method for these challenging samples. Testing two readily available electrostatic devices for their potential to sample biological material from garments made of different fabrics, we found one of them, the electrostatic dust print lifter (DPL), to perform comparable to well-established sampling with wet cotton swabs. In simulated aggression scenarios, we had the same success rate for the establishment of single aggressor profiles, suitable for database submission, with both the DPL and wet swabbing. However, we lost a substantial amount of information with electrostatic sampling, since almost no mixed aggressor-victim profiles suitable for database entry could be established, compared to conventional swabbing. This study serves as a proof of principle for electrostatic DNA sampling from items of clothing. The technique still requires optimization before it might be used in real casework. But we are confident that in the future it could be an efficient and convenient contribution to the toolbox of forensic practitioners.
