Long Term Recovery Planning Task Force Report, August 2008

Eighty-five of 99 Iowa counties were declared Presidential Disaster Areas for Public Assistance and/orIndividual Assistance as a result of the tornadoes, storms, and floods over the incident period May 25 through August 13, 2008. Response dominated the state’s attention for weeks, with a transition to recovery as the local situations warranted. The widespread damage and severity of the impact on Iowans and their communities required a statewide effort to continue moving forward despite being surrounded by adversity. By all accounts, it will require years for the state to recover from these disasters. With an eye toward the future, recovery is underway across Iowa. As part of the Rebuild Iowa efforts, the Long Term Recovery Planning Task Force was charged with responsibilities somewhat different from other topical Task Force assignments. Rather than assess damage and report on how the state might address immediate needs, the Long Term Recovery Planning Task Force is directed to discuss and discern the best approach to the lengthy recovery process. Certainly, the Governor and Lieutenant Governor expect the task to be difficult; when planning around so many critical issues and overwhelming needs, it is challenging to think to the future, rather than to rise to the current day’s needs.

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.

Cyclododecane exposure in the field of conservation and restoration of art objects

PURPOSE: Recent work practices in the conservation and restoration involve the use of cyclododecane (CDD, CAS 294-62-2) to protect fragile artifacts during their handling or transportation. Little is known about its toxicity, and no previous exposure has been reported. A short field investigation was conducted to characterize the exposure conditions to both CDD vapors and aerosols.METHODS: Measurements were conducted in the laboratory of conservation and restoration of the archeological service in Bern (Switzerland). Three indoor and four outdoor typical work situations, either during brush or spray gun applications, were investigated. Measurements were performed on charcoal adsorbent tube and analyzed by a gas chromatograph equipped with a flame ionization detector.RESULTS: Measurements have been conducted during both brush and spray gun applications. Indoor exposures were of 0.75-15.5 mg/m(3), while outdoors exposures were 19.5-53.9 mg/m(3). Exposures appear to be extremely localized due to both physicochemical properties and application methods of the CDD. Vapor exposure increases dramatically with the confinement of the workplace.CONCLUSION: Preventive measures should be undertaken to limit as much as possible these exposures. Field work in confined areas (ditches, underground) is of particular concern. CDD-coated artifacts or materials should be stored in ventilated areas to avoid delayed exposures. [Authors]

Exposition aux endotoxines : effets protecteurs contre les allergies mais augmentation des problèmes respiratoires chroniques et aigus

Les endotoxines aéroportées sont connues pour provoquer des inflammations des voies respiratoires et une altération des fonctions pulmonaires. De très nombreuses études ont montré que les professions où l'on manipule de la matière organique (manipulation de déchets, élevage d'animaux, cultures maraîchères et céréalières, transformation d'aliments, etc...) sont sujettes à une exposition professionnelle aux endotoxines très élevée. Ce qui génère l'apparition de divers problèmes de santé, notamment des problèmes respiratoires. Paradoxalement, plusieurs études récentes, en particulier sur des éleveurs, ont montré que l'exposition aux endotoxines pouvait avoir des effets bénéfiques pour la santé en prévenant les allergies et les maladies atopiques. De plus, il a été démontré que les enfants ayant passé leurs premières années de vie dans des exploitations agricoles avec des animaux ont une probabilité moindre de développer des allergies à l'âge adulte. L'article original et la revue bibliographique analysés dans cette note traitent de cette dualité des effets sur la santé d'une exposition prolongée aux endotoxines. [Auteur]

The Capitol Planning Commission is authorized under Chapter 8A.371—378 of the Code of Iowa. “It shall be the duty of the commission to advise upon the location of statues, fountains and monuments and the placing of any additional buildings on the capitol grounds, the type of architecture and the type of construction of any new buildings to be erected on the state capitol grounds as now encompassed or as subsequently enlarged, and repairs and restoration thereof, and it shall be the duty of the officers, commissions, and councils charged by law with the duty of determining such questions to call upon the commission for such advice. “The commission shall, in cooperation with the director of the department of administrative services, develop and implement within the limits of its appropriation, a five-year modernization program for the capitol complex. “The commission shall annually report to the general assembly its recommendations relating to its duties under this section. The report shall be submitted to the chief clerk of the house and the secretary of the senate during the month of January.” —Code of Iowa, Chapter 8A.373

Comparative testing of a miniature diffusion size classifier to assess airborne ultrafine particles under field conditions

Miniature diffusion size classifiers (miniDiSC) are novel handheld devices to measure ultrafine particles (UFP). UFP have been linked to the development of cardiovascular and pulmonary diseases; thus, detection and quantification of these particles are important for evaluating their potential health hazards. As part of the UFP exposure assessments of highwaymaintenance workers in western Switzerland, we compared a miniDiSC with a portable condensation particle counter (P-TRAK). In addition, we performed stationary measurements with a miniDiSC and a scanning mobility particle sizer (SMPS) at a site immediately adjacent to a highway. Measurements with miniDiSC and P-TRAK correlated well (correlation of r = 0.84) but average particle numbers of the miniDiSC were 30%âeuro"60% higher. This difference was significantly increased for mean particle diameters below 40 nm. The correlation between theminiDiSC and the SMPSduring stationary measurements was very high (r = 0.98) although particle numbers from the miniDiSC were 30% lower. Differences between the three devices were attributed to the different cutoff diameters for detection. Correction for this size dependent effect led to very similar results across all counters.We did not observe any significant influence of other particle characteristics. Our results suggest that the miniDiSC provides accurate particle number concentrations and geometric mean diameters at traffic-influenced sites, making it a useful tool for personal exposure assessment in such settings.

State of Iowa Department of Administrative Services Human Resource Enterprise: Review of State Hiring Practices, April 30, 2007

The State of Iowa and the Hiring Practices Working Group commissioned this review of the State’s hiring practices in response to recent concerns about these practices involving racial discrimination claims against the Departments of Human Services, Transportation, and Iowa Workforce Development. The State of Iowa should be commended for undertaking this review. The State has a longstanding Affirmative Action Program and commitment to diversity – they instituted their Affirmative Action Program in 1973, and continue their commitment to its success by making the changes necessary to ensure the program is viable and sustainable. Iowa Department of Administrative Services In July 2003, the State created the Iowa Department of Administrative Services (DAS) as a way to manage and coordinate the major resources of state government. DAS provides human resource services through an entrepreneurial management model. Entrepreneurial management is a customer-focused approach to delivering services. The customer departments have input about what services and products they want from DAS and in turn DAS is funded by the customer departments through purchases of DAS services and products. DAS looks to offer new and additional services (for example recruitment support and coordination) to various customers on a fee-for-service basis. A customer council is charged with approving the DAS business plan, establishing the rate for services, and reviewing service delivery and complaints. Under this entrepreneurial model, human resource services are provided by DAS-HRE (Human Resources Enterprise) central staff, 12 DAS-HRE Personnel Officers located at the customer departments, and customer agency staff. The majority of the recruitment and hiring functions are done by the customer (hiring) departments and their staff. Applications for employment are submitted using the BrassRing system with applicants being qualified by DAS-HRE employees. Since the creation of Human Resources Enterprise, DAS-HRE has strived to provide human resource tools to the departments. The Screening Manual and the Supervisor’s Manual are just two examples of the resources created for the hiring departments. They also provide Supervisor Training for newly appointed supervisors. Larger departments have dedicated staff assigned to human resource activities. The staff at the departmental level may or may not have a human resources background. Iowa Population and Workforce The 2000 U.S. Census indicated that Iowa’s population was 2,926,324. According to this census, 92.6 percent of Iowa’s population identified their race as white (alone). The nonwhite alone or minority population (including Black or African American, Asian, Native Hawaiian or Pacific Islander, Hispanic or Latino, American Indian or Alaska Native, two or more races, or some other race) was 7.4 percent.

Relationship and transaction lending in a crisis

We study how relationship lending and transaction lending varyover the business cycle. We develop a model in which relationshipbanks gather information on their borrowers, which allows them toprovide loans for profitable firms during a crisis. Due to the servicesthey provide, operating costs of relationship-banks are higher thanthose of transaction-banks. In our model, where relationship-bankscompete with transaction-banks, a key result is that relationship-banks charge a higher intermediation spread in normal times, butoffer continuation-lending at more favorable terms than transactionbanks to profitable firms in a crisis. Using detailed credit registerinformation for Italian banks before and after the Lehman Brothers'default, we are able to study how relationship and transaction-banksresponded to the crisis and we test existing theories of relationshipbanking. Our empirical analysis confirms the basic prediction of themodel that relationship banks charged a higher spread before the crisis, offered more favorable continuation-lending terms in response tothe crisis, and suffered fewer defaults, thus confirming the informational advantage of relationship banking.

Molecular basis of coagulation factor V deficiency caused by the R1698W inter-domain mutation.

Coagulation factor V (FV) deficiency is characterised by variable bleeding phenotypes and heterogeneous mutations. To add new insights into the FV genotype-phenotype relationship, we characterised the R1698W change in the A3 domain, at the poorly investigated interface with the A2 domain. The FV R1698W mutation was responsible for a markedly reduced expression level (10% of FV-WT) and specific activity in thrombin generation (0.39). Interestingly, the FVa1698W showed rapid activity decay upon activation due to increased dissociation rate between the heavy and light chains. The importance of the size and charge of the residue at position 1698 was investigated by three additional recombinant mutants, FVR1698A, FVR1698Q, and FVR1698E. FVR1698A and FVR1698Q expression (30 and 45% of FV-WT), specific activity (both 0.57) and stability were all reduced. Noticeably, FVR1698E showed normal activity and stability despite poor expression (10% of FV-WT). These data indicate the essential role of R1698 for normal biosynthetic process and support local flexibility for positively or negatively charged residues to produce stable and functional A3-A2 domain interactions. Their experimental alteration produces a gradient of FV defects, which help to interpret the wide spectrum of phenotypes in FV-deficient patients.

Structure-function characterization and optimization of a plant-derived antibacterial peptide.

Crushed seeds of the Moringa oleifera tree have been used traditionally as natural flocculants to clarify drinking water. We previously showed that one of the seed peptides mediates both the sedimentation of suspended particles such as bacterial cells and a direct bactericidal activity, raising the possibility that the two activities might be related. In this study, the conformational modeling of the peptide was coupled to a functional analysis of synthetic derivatives. This indicated that partly overlapping structural determinants mediate the sedimentation and antibacterial activities. Sedimentation requires a positively charged, glutamine-rich portion of the peptide that aggregates bacterial cells. The bactericidal activity was localized to a sequence prone to form a helix-loop-helix structural motif. Amino acid substitution showed that the bactericidal activity requires hydrophobic proline residues within the protruding loop. Vital dye staining indicated that treatment with peptides containing this motif results in bacterial membrane damage. Assembly of multiple copies of this structural motif into a branched peptide enhanced antibacterial activity, since low concentrations effectively kill bacteria such as Pseudomonas aeruginosa and Streptococcus pyogenes without displaying a toxic effect on human red blood cells. This study thus identifies a synthetic peptide with potent antibacterial activity against specific human pathogens. It also suggests partly distinct molecular mechanisms for each activity. Sedimentation may result from coupled flocculation and coagulation effects, while the bactericidal activity would require bacterial membrane destabilization by a hydrophobic loop.

Application of real-time PCR for total airborne bacterial assessment : comparison with epifluorescence microscopy and culture-dependent methods

Traditional culture-dependent methods to quantify and identify airborne microorganisms are limited by factors such as short-duration sampling times and inability to count nonculturableor non-viable bacteria. Consequently, the quantitative assessment of bioaerosols is often underestimated. Use of the real-time quantitative polymerase chain reaction (Q-PCR) to quantify bacteria in environmental samples presents an alternative method, which should overcome this problem. The aim of this study was to evaluate the performance of a real-time Q-PCR assay as a simple and reliable way to quantify the airborne bacterial load within poultry houses and sewage treatment plants, in comparison with epifluorescencemicroscopy and culture-dependent methods. The estimates of bacterial load that we obtained from real-time PCR and epifluorescence methods, are comparable, however, our analysis of sewage treatment plants indicate these methods give values 270-290 fold greater than those obtained by the ''impaction on nutrient agar'' method. The culture-dependent method of air impaction on nutrient agar was also inadequate in poultry houses, as was the impinger-culture method, which gave a bacterial load estimate 32-fold lower than obtained by Q-PCR. Real-time quantitative PCR thus proves to be a reliable, discerning, and simple method that could be used to estimate airborne bacterial load in a broad variety of other environments expected to carry high numbers of airborne bacteria.

Empirical studies of cloud effects on UV radiation: A review

The interest in solar ultraviolet (UV) radiation from the scientific community and the general population has risen significantly in recent years because of the link between increased UV levels at the Earth's surface and depletion of ozone in the stratosphere. As a consequence of recent research, UV radiation climatologies have been developed, and effects of some atmospheric constituents (such as ozone or aerosols) have been studied broadly. Correspondingly, there are well-established relationships between, for example, total ozone column and UV radiation levels at the Earth's surface. Effects of clouds, however, are not so well described, given the intrinsic difficulties in properly describing cloud characteristics. Nevertheless, the effect of clouds cannot be neglected, and the variability that clouds induce on UV radiation is particularly significant when short timescales are involved. In this review we show, summarize, and compare several works that deal with the effect of clouds on UV radiation. Specifically, works reviewed here approach the issue from the empirical point of view: Some relationship between measured UV radiation in cloudy conditions and cloud-related information is given in each work. Basically, there are two groups of methods: techniques that are based on observations of cloudiness (either from human observers or by using devices such as sky cameras) and techniques that use measurements of broadband solar radiation as a surrogate for cloud observations. Some techniques combine both types of information. Comparison of results from different works is addressed through using the cloud modification factor (CMF) defined as the ratio between measured UV radiation in a cloudy sky and calculated radiation for a cloudless sky. Typical CMF values for overcast skies range from 0.3 to 0.7, depending both on cloud type and characteristics. Despite this large dispersion of values corresponding to the same cloud cover, it is clear that the cloud effect on UV radiation is 15–45% lower than the cloud effect on total solar radiation. The cloud effect is usually a reducing effect, but a significant number of works report an enhancement effect (that is increased UV radiation levels at the surface) due to the presence of clouds. The review concludes with some recommendations for future studies aimed to further analyze the cloud effects on UV radiation
