Electronic Payments for Driver's Licensing Transactions,December 31, 2008

House File 2196 required the Department of Transportation (DOT) to study the acceptance of electronic payments at its customer service sites and sites operated by county treasurers. Specifically the legislation requires the following: “The department of transportation shall review the current methods the department employs for the collection of fees and other revenues at sites operated by county treasurers under chapter 321M and at customer service sites operated by the department. In conducting its review, the department, in cooperation with the treasurer of state, shall consider providing an electronic payment option for all of its customers. The department shall report its findings and recommendations by December 31, 2008, to the senate and house standing committees on transportation regarding the advantages and disadvantages of implementing one or more electronic payment systems.” This review focused on estimating the costs of providing an electronic payment option for customers of the DOT driver’s license stations and those of the 81 county treasurers. Customers at these sites engage in three primary financial transactions for which acceptance of electronic payments was studied: paying for a driver’s license (DL), paying for a non-operator identification card (ID), and paying certain civil penalties. Both consumer credit cards and PIN-based debit cards were reviewed as electronic payment options. It was assumed that most transactions would be made using a consumer credit card. Credit card companies charge a fee for each transaction for which they are used. The amount of these fees varies among credit card companies. The estimates for credit card fees used in this study were based on the State Treasurer of Iowa’s current credit card contract, which is due to expire in September 2009. Since credit card companies adjust their fees each year, estimates were based on the 2008 fee schedule. There is also a fee for the use of PIN-based debit cards. The estimates for PIN-based debit card transactions were based on information provided by Wells Fargo Merchant Services for current fees charged by debit card networks. Credit and debit card transactions would be processed through vendor-provided hardware and software. The costs would be determined through the competitive bidding process since several vendors provide this function; therefore, these costs are not reflected in this document.

Metaheuristics for the bus-driver scheduling problem

We present new metaheuristics for solving real crew scheduling problemsin a public transportation bus company. Since the crews of thesecompanies are drivers, we will designate the problem by the bus-driverscheduling problem. Crew scheduling problems are well known and severalmathematical programming based techniques have been proposed to solvethem, in particular using the set-covering formulation. However, inpractice, there exists the need for improvement in terms of computationalefficiency and capacity of solving large-scale instances. Moreover, thereal bus-driver scheduling problems that we consider can present variantaspects of the set covering, as for example a different objectivefunction, implying that alternative solutions methods have to bedeveloped. We propose metaheuristics based on the following approaches:GRASP (greedy randomized adaptive search procedure), tabu search andgenetic algorithms. These metaheuristics also present some innovationfeatures based on and genetic algorithms. These metaheuristics alsopresent some innovation features based on the structure of the crewscheduling problem, that guide the search efficiently and able them tofind good solutions. Some of these new features can also be applied inthe development of heuristics to other combinatorial optimizationproblems. A summary of computational results with real-data problems ispresented.

On the structural difference between the evolutionary approach of Young and that of Kandori, Mailath and Rob

We provide robust examples of symmetric two-player coordination games in normal form that reveal that equilibrium selection bythe evolutionary model of Young (1993) is essentially different from equilibrium selection by the evolutionary model of Kandori, Mailath and Rob (1993).

Acute ischemic stroke in children versus young adults.

Objective: The aim of this study was to compare children and young adults with acute ischemic stroke (AIS) in 2 large registries.Methods: We compared clinical characteristics, stroke etiology, workup, and outcome (modified Rankin scale score [mRS] at 3-6 months) in children (1 month-16 years) and young adults (16.1-45 years) with AIS. Data of children were collected prospectively in the nationwide Swiss NeuroPediatric Stroke Registry, young adults in the Bernese stroke database. Outcome (mRS) and stroke severity (pediatric adaptation of the National Institutes of Health stroke scale [PedNIHSS]) in children were calculated retrospectively.Results: From January 2000 to December 2008, 128 children and 199 young adults suffered from an AIS. Children were more likely to be male than young adults (62%/49%, p = 0.023) and less frequently had hypertension (p = 0.001), hypercholesterolemia (p = 0.003), and a family history of stroke (p = 0.048). Stroke severity was similar in children and young adults (median PedNIHSS/NIHSS 5/6; p = 0.102). Stroke etiology (original TOAST classification) was more likely to be "other determined cause" in children than in young adults (51%/29%; p < .001). Cervicocerebral artery dissections were less frequent in children than in young adults (10%/23%; p = 0.005). Outcome at 3 to 6 months did not differ between children and young adults (p = 0.907); 59% of children and 60% of young adults had a favorable outcome (mRS 0-1). Mortality was similar among children and young adults (4%/6%; p = 0.436). In multivariate analysis, low PedNIHSS/NIHSS was the most important predictor of favorable outcome (p < 0.001).Interpretation: Although stroke etiology and risk factors in children and young adults are different, stroke severity and clinical outcome were similar in both groups.

Commercial Driver's License in a Nutshell, March 2009

Federal law requires uniform licensing of truck and bus drivers (CDL) in all states and the District of Columbia. Commercial Driver's License (CDL) testing and issuance began in Iowa November 1, 1990. A person applying for a license to operate a commercial motor vehicle must apply for a CDL.

Weight status and gender-related differences in motor skills and in child care - based physical activity in young children.

Over the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical activity according to weight or gender were already present in 2- to 4-year-old children. Fifty-eight child care centers in the French part of Switzerland were randomly selected for the Youp'là bouge study. Motor skills were assessed by an obstacle course including 5 motor skills, derived from the Zurich Neuromotor Assessment test. Physical activity was measured with accelerometers (GT1M, Actigraph, Florida, USA) using age-adapted cut-offs. Weight status was assessed using the International Obesity Task Force criteria (healthy weight vs overweight) for body mass index (BMI). Of the 529 children (49% girls, 3.4 ± 0.6 years, BMI 16.2 ± 1.2 kg/m2), 13% were overweight. There were no significant weight status-related differences in the single skills of the obstacle course, but there was a trend (p = 0.059) for a lower performance of overweight children in the overall motor skills score. No significant weight status-related differences in child care-based physical activity were observed. No gender-related differences were found in the overall motor skills score, but boys performed better than girls in 2 of the 5 motor skills (p ≤ 0.04). Total physical activity as well as time spent in moderate-vigorous and in vigorous activity during child care were 12-25% higher and sedentary activity 5% lower in boys compared to girls (all p < 0.01). At this early age, there were no significant weight status- or gender-related differences in global motor skills. However, in accordance to data in older children, child care-based physical activity was higher in boys compared to girls. These results are important to consider when establishing physical activity recommendations or targeting health promotion interventions in young children.

You’re the COACH!: A Guide for Parents of New Drivers, June 23, 2008

This publication is a guide for parents and guardians of teenagers learning to drive. It should be used with the Iowa Driver’s Manual to aid you in instructing your new driver about how to safely and responsibly operate a motor vehicle. Since the task of driving is affected by changing conditions, this manual does not attempt to cover all situations that may arise. Under Iowa’s graduated driver licensing system young drivers must complete 20 hours of supervised drive time with their parents or guardians during the instruction permit stage and 10 hours during the intermediate license stage. Even though your teenager is taking or has completed driver education in school, there is a great deal of benefit to be obtained from you providing this additional practice time. Learning from your experience and under your guidance, your teenager will apply the rules of the road and more fully understand the risks involved in driving. This will require time and patience on your part, but the effort will result in you knowing that your teenager will be better able to cope with the demands of safe driving. In the back of this manual you will find several pages of diagrams. Use these diagrams to illustrate different driving situations for your teenage driver. Consider taking a notepad and pencil along during your practice sessions for additional drawings. This manual also contains a chart to log your supervised drive time. As your new driver advances through the graduated system you will be required to certify to an Iowa driver’s license examiner that you completed the minimum number of hours of supervised drive time. By becoming involved in the learning driver’s educational process, you are contributing to Iowa’s overall highway safety effort and helping your teenager develop safe driving habits that will last a lifetime.

Which clinical signs predict hypoxaemia in young Senegalese children with acute lower respiratory tract disease?

BACKGROUND: Acute lower respiratory tract diseases are an important cause of mortality in children in resource-limited settings. In the absence of pulse oximetry, clinicians rely on clinical signs to detect hypoxaemia. OBJECTIVE: To assess the diagnostic value of clinical signs of hypoxaemia in children aged 2 months to 5 years with acute lower respiratory tract disease. METHODS: Seventy children with a history of cough and signs of respiratory distress were enrolled. Three experienced physicians recorded clinical signs and oxygen saturation by pulse oximetry. Hypoxaemia was defined as oxygen saturation <90%. Clinical predictors of hypoxaemia were evaluated using adjusted diagnostic odds ratios (aDOR). RESULTS: There was a 43% prevalence of hypoxaemia. An initial visual impression of poor general status [aDOR 20·0, 95% CI 3·8-106], severe chest-indrawing (aDOR 9·8, 95% CI 1·5-65), audible grunting (aDOR 6·9, 95% CI 1·4-25) and cyanosis (aDOR 26·5, 95% CI 1·1-677) were significant predictors of hypoxaemia. CONCLUSION: In children under 5 years of age, several simple clinical signs are reliable predictors of hypoxaemia. These should be included in diagnostic guidelines.

The contribution of the young Cretaceous Caribbean Oceanic Plateau to the genesis of late Cretaceous arc magmatism in the Cordillera Occidental of Ecuador

The eastern part of the Cordillera Occidental of Ecuador comprises thick buoyant oceanic plateaus associated with island-arc tholeiites and subduction-related calc-alkaline series, accreted to the Ecuadorian Continental Margin from Late Cretaceous to Eocene times. One of these plateau sequences, the Guaranda Oceanic Plateau is considered as remnant of the Caribbean-Colombian Oceanic Province (CCOP) accreted to the Ecuadorian Margin in the Maastrichtien. Samples studied in this paper were taken from four cross-sections through two arc-sequences in the northern part of the Cordillera Occidental of Ecuador, dated as (Rio Cala) or ascribed to (Macuchi) the Late Cretaceous and one arc-like sequence in the Chogon-Colonche Cordillera (Las Orquideas). These three island-arcs can clearly be identified and rest conformably on the CCOP. In all four localities, basalts with abundant large clinopyroxene phenocrysts can be found, mimicking a picritic or ankaramitic facies. This mineralogical particularity, although not uncommon in island arc lavas, hints at a contribution of the CCOP in the genesis of these island arc rocks. The complete petrological and geochemical study of these rocks reveals that some have a primitive island-arc nature (MgO values range from 6 to 11 wt.%). Studied samples display marked Nb, Ta and Ti negative anomalies relative to the adjacent elements in the spidergrams characteristic of subductionrelated magmatism. These rocks are LREE-enriched and their clinopyroxenes show a tholeiitic affinity (FeO(1)-TiO(2) enrichment and CaO depletion from core to rim within a single crystal). The four sampled cross-sections through the island-arc sequences display homogeneous initial Nd, and Pb isotope ratios that suggest a unique mantellic source for these rocks resulting from the mixing of three components: an East-Pacific MORB end-member, an enriched pelagic sediment component, and a HIMU component carried by the CCOP. Indeed, the ankaramite and Mg-basalt sequences that form part of the Caribbean-Colombian Oceanic Plateau are radiogenically enriched in (206)Pb/(204)Pb and (207)Pb/(204)Pb and contain a HIMU component similar to that observed in the Gorgona basalts and Galapagos lavas. The subduction zone that generated the Late Cretaceous arcs occurred far from the continental margin, in an oceanic environment. This implies that no terrigenous detrital sediments interacted with the source at this period. Thus, the enriched component can only result from the melting of subducted pelagic sediments. We have thus defined the East-Pacific MORB, enriched (cherts, pelagic sediments) and HIMU components in an attempt to constrain and model the genesis of the studied island-arc magmatism, using a compilation of carefully selected isotopic data from literature according to rock age and paleogeographic location at the time of arc edification. Tripolar mixing models reveal that proportions of 12-15 wt.% of the HIMU component, 7-15 wt.% of the pelagic sediment end-member and 70-75 wt.% of an East-pacific MORB end-member are needed to explain the measured isotope ratios. These surprisingly high proportions of the HIMU/CCOP component could be explained by the young age of the oceanic plateau (5-15 Ma) during the Late Cretaceous arc emplacement. The CCOP, basement of these arc sequences, was probably still hot and easily assimilated at the island-arc lava source. (C) 2008 Elsevier Ltd. All rights reserved,

How to screen for problematic cannabis use in population surveys: an evaluation of the Cannabis Use Disorders Identification Test (CUDIT) in a Swiss sample of adolescents and young adults.

BACKGROUND/AIMS: Cannabis use is a growing challenge for public health, calling for adequate instruments to identify problematic consumption patterns. The Cannabis Use Disorders Identification Test (CUDIT) is a 10-item questionnaire used for screening cannabis abuse and dependency. The present study evaluated that screening instrument. METHODS: In a representative population sample of 5,025 Swiss adolescents and young adults, 593 current cannabis users replied to the CUDIT. Internal consistency was examined by means of Cronbach's alpha and confirmatory factor analysis. In addition, the CUDIT was compared to accepted concepts of problematic cannabis use (e.g. using cannabis and driving). ROC analyses were used to test the CUDIT's discriminative ability and to determine an appropriate cut-off. RESULTS: Two items ('injuries' and 'hours being stoned') had loadings below 0.5 on the unidimensional construct and correlated lower than 0.4 with the total CUDIT score. All concepts of problematic cannabis use were related to CUDIT scores. An ideal cut-off between six and eight points was found. CONCLUSIONS: Although the CUDIT seems to be a promising instrument to identify problematic cannabis use, there is a need to revise some of its items.

Low prevalence of Chlamydia trachomatis infection in asymptomatic young Swiss men

BACKGROUND: Prevalence and risk factors for Chlamydia trachomatis infection among young men in Switzerland is still unknown. The objective of the present study was to assess prevalence and risk factors for C. trachomatis infection in young Swiss men. METHODS: 517 young Swiss men were enrolled in this cross-sectional study during their compulsory military recruitment. Participants completed a questionnaire and gave urine samples which were screened for C. trachomatis DNA by PCR. Genotyping of positive samples was done by amplification and sequencing the ompA gene. RESULTS: The prevalence of chlamydial infection among young Swiss male was 1.2% (95% confidence interval [95%CI], 0.4-2.5%). C. trachomatis infection was only identified among the 306 men having multiple sexual partner. Although frequent, neither unprotected sex (absence of condom use), nor alcohol and drug abuse were associated with chlamydial infection. Men living in cities were more frequently infected (2.9%, 95%CI 0.8-7.4%) than men living in rural areas (0.5%, 95%CI 0.1-1.9%, p = 0.046). Moreover, naturalised Swiss citizens were more often positive (4.9%, 95%CI 1.3-12.5%) than native-born Swiss men (0.5%, 95%CI 0.1-1.7%, p = 0.003). CONCLUSION: In comparison with other countries, the prevalence of chlamydial infection in men is extremely low in Switzerland, despite a significant prevalence of risky sexual behaviour. C. trachomatis infection was especially prevalent in men with multiple sexual partners. Further research is required (i) to define which subgroup of the general population should be routinely screened, and (ii) to test whether such a targeted screening strategy will be effective to reduce the prevalence of chlamydial infection among this population.

Role of high normal gamma-glutamyltransferase level in identifying heavy alcohol use in young men.

The objective of the current study was to determine the predictive value of high normal gamma-glutamyltransferase (GGT) level as an indication of heavy drinking in young men. In a sample of 577 men attending a one-day army recruitment process mandatory for all Swiss men at age 19 years, GGT level was evaluated as the dependent variable for each of eight dichotomous classifications of individuals on the basis of meeting cut-off criteria for five indexes of alcohol use, two indexes of alcohol-related problems, and one index of body mass. The sensitivity, specificity, and predictive values of GGT level in identifying subjects as either heavy drinkers or being overweight were determined. Compared with findings for their counterparts, GGT level was higher in subjects reporting consumption of more than 14 drinks per week (20.5 +/- 7.81 vs. 18.9 +/- 7.60, P <.05), in those reporting being drunk at least once during the past 30 days (20.3 +/- 7.80 vs. 18.3 +/- 7.43, P <.001), and in individuals with body mass indexes >or=25 kg/m(2) (25.8 +/- 10.84 vs. 18.3 +/- 6.59, P <.001). At a GGT level cut-off of 20 U/l, the sensitivity, specificity, and positive and negative predictive values of either being a heavy drinker or overweight were 48.2%, 70.2%, 67.7%, and 51.2%, respectively. Exclusion of subjects with body mass indexes of >or=25 kg/m(2) revealed similar results. High normal GGT level in young men is indicative of heavy alcohol use or being overweight; when present, subjects should be screened further for potential concomitant drinking problems.
