Investigation of the Lane-Wells Road Logger, HR-113, 1966

The Lane-Wells Road Logger was utilized primarily to determine the feasibility of employing such a device for moisture and density control in Iowa highway construction. A secondary objective was the use of the Road Logger to obtain information concerning moisture content and density during and after construction. Correlation studies with conventional test results required a small portion of the lease period. Practically all phases of construction and most materials utilized in base and surface courses were surveyed. Results of this study were good, in general, with the Road Logger indicating dry density slightly higher and the moisture content slightly lower than conventional results in most instances. Economic feasibility seemed to pose the greatest problem for the acceptance of the Road Logger as a standard compaction control device. It would appear from the findings of this study that probably only large projects, or several smaller contracts tested simultaneously, could justify the expense of the Logger. A total of about 128 miles were surveyed with the Logger during the lease period. Approximately 16 days of downtime due to minor breakdowns were recorded. Inclement weather forcing construction delays resulted in several idle days in which the Logger's full capabilities were not realized.

The law of impersonal transactions

Most economic interactions happen in a context of sequential exchangein which innocent third parties suffer information asymmetry with respect toprevious "originative" contracts. The law reduces transaction costs byprotecting these third parties but preserves some element of consent byproperty rightholders to avoid damaging property enforcement?e.g., it isthey, as principals, who authorize agents in originative contracts. Judicialverifiability of these originative contracts is obtained either as an automaticbyproduct of transactions or, when these would have remained private, byrequiring them to be made public. Protecting third parties produces a legalcommodity which is easy to trade impersonally, improving the allocationand specialization of resources. Historical delay in generalizing this legalcommoditization paradigm is attributed to path dependency?the law firstdeveloped for personal trade?and an unbalance in vested interests, asluddite legal professionals face weak public bureaucracies.

Leverage and beliefs: Personal experience and risk taking in margin lending

What determines risk-bearing capacity and the amount of leverage in financial markets? Thispaper uses unique micro-data on collateralized lending contracts during a period of financialdistress to address this question. An investor syndicate speculating in English stocks wentbankrupt in 1772. Using hand-collected information from Dutch notarial archives, we examinechanges in lenders' behavior following exposure to potential (but not actual) losses. Before thedistress episode, financiers that lent to the ill-fated syndicate were indistinguishable from therest. Afterwards, they behaved differently: they lent with much higher haircuts. Only lendersexposed to the failed syndicate altered their behavior. The differential change is remarkable sincethe distress was public knowledge, and because none of the lenders suffered actual losses ? allfinanciers were repaid in full. Interest rates were also unaffected; the market balanced solelythrough changes in collateral requirements. Our findings are consistent with a heterogeneousbeliefs-interpretation of leverage. They also suggest that individual experience can modify thelevel of leverage in a market quickly.

Development of Object-Oriented Design and Specifications for Iowa DOT and Urban Standards: Phase I, TR-487, 2004

Currently, individuals including designers, contractors, and owners learn about the project requirements by studying a combination of paper and electronic copies of the construction documents including the drawings, specifications (standard and supplemental), road and bridge standard drawings, design criteria, contracts, addenda, and change orders. This can be a tedious process since one needs to go back and forth between the various documents (paper or electronic) to obtain information about the entire project. Object-oriented computer-aided design (OO-CAD) is an innovative technology that can bring a change to this process by graphical portrayal of information. OO-CAD allows users to point and click on portions of an object-oriented drawing that are then linked to relevant databases of information (e.g., specifications, procurement status, and shop drawings). The vision of this study is to turn paper-based design standards and construction specifications into an object-oriented design and specification (OODAS) system or a visual electronic reference library (ERL). Individuals can use the system through a handheld wireless book-size laptop that includes all of the necessary software for operating in a 3D environment. All parties involved in transportation projects can access all of the standards and requirements simultaneously using a 3D graphical interface. By using this system, users will have all of the design elements and all of the specifications readily available without concerns of omissions. A prototype object-oriented model was created and demonstrated to potential users representing counties, cities, and the state. Findings suggest that a system like this could improve productivity to find information by as much as 75% and provide a greater sense of confidence that all relevant information had been identified. It was also apparent that this system would be used by more people in construction than in design. There was also concern related to the cost to develop and maintain the complete system. The future direction should focus on a project-based system that can help the contractors and DOT inspectors find information (e.g., road standards, specifications, instructional memorandums) more rapidly as it pertains to a specific project.

Resilient housing : a new resource-oriented approach

The institutional regimes framework has previously been applied to the institutional conditions that support or hinder the sustainability of housing stocks. This resource-based approach identifies the actors across different sectors that have an interest in housing, how they use housing, the mechanisms affecting their use (public policy, use rights, contracts, etc.) and the effects of their uses on the sustainability of housing within the context of the built environment. The potential of the institutional regimes framework is explored for its suitability to the many considerations of housing resilience. By identifying all the goods and services offered by the resource 'housing stock', researchers and decision-makers could improve the resilience of housing by better accounting for the ecosystem services used by housing, decreasing the vulnerability of housing to disturbances, and maximizing recovery and reorganization following a disturbance. The institutional regimes framework is found to be a promising tool for addressing housing resilience. Further questions are raised for translating this conceptual framework into a practical application underpinned with empirical data.

This is a annual report about these living arrangements and how the Department of Human Services contracts them.

Optimal stop-loss reinsurance: a dependence analysis

The stop-loss reinsurance is one of the most important reinsurance contracts in the insurance market. From the insurer point of view, it presents an interesting property: it is optimal if the criterion of minimizing the variance of the cost of the insurer is used. The aim of the paper is to contribute to the analysis of the stop-loss contract in one period from the point of view of the insurer and the reinsurer. Firstly, the influence of the parameters of the reinsurance contract on the correlation coefficient between the cost of the insurer and the cost of the reinsurer is studied. Secondly, the optimal stop-loss contract is obtained if the criterion used is the maximization of the joint survival probability of the insurer and the reinsurer in one period.

2012 Iowa Small Hospital Improvement Program (SHIP) Briefing and Survey Report, January 22, 2013

In August of 2012 the Iowa State Office of Rural Health (SORH) conducted a survey to determine the value of the Small Rural Hospital Improvement Program (SHIP) in Iowa. This survey was distributed to the 84 participating hospitals however, because some hospitals network their SHIP funds we only asked the contract administrators of the contracts to complete the survey. 58 of the 78 SHIP contract administrators completed the survey (74%). Background: SHIP brings in roughly $750,000.00 annually to Iowa to assist small Iowa hospitals. Average distribution of approximately $7,500 per hospital. Seventy three of ninety nine Iowa counties are represented.

Modeling and mitigation of supply-demand mismatches

In this thesis, I develop analytical models to price the value of supply chain investments under demand uncer¬tainty. This thesis includes three self-contained papers. In the first paper, we investigate the value of lead-time reduction under the risk of sudden and abnormal changes in demand forecasts. We first consider the risk of a complete and permanent loss of demand. We then provide a more general jump-diffusion model, where we add a compound Poisson process to a constant-volatility demand process to explore the impact of sudden changes in demand forecasts on the value of lead-time reduction. We use an Edgeworth series expansion to divide the lead-time cost into that arising from constant instantaneous volatility, and that arising from the risk of jumps. We show that the value of lead-time reduction increases substantially in the intensity and/or the magnitude of jumps. In the second paper, we analyze the value of quantity flexibility in the presence of supply-chain dis- intermediation problems. We use the multiplicative martingale model and the "contracts as reference points" theory to capture both positive and negative effects of quantity flexibility for the downstream level in a supply chain. We show that lead-time reduction reduces both supply-chain disintermediation problems and supply- demand mismatches. We furthermore analyze the impact of the supplier's cost structure on the profitability of quantity-flexibility contracts. When the supplier's initial investment cost is relatively low, supply-chain disin¬termediation risk becomes less important, and hence the contract becomes more profitable for the retailer. We also find that the supply-chain efficiency increases substantially with the supplier's ability to disintermediate the chain when the initial investment cost is relatively high. In the third paper, we investigate the value of dual sourcing for the products with heavy-tailed demand distributions. We apply extreme-value theory and analyze the effects of tail heaviness of demand distribution on the optimal dual-sourcing strategy. We find that the effects of tail heaviness depend on the characteristics of demand and profit parameters. When both the profit margin of the product and the cost differential between the suppliers are relatively high, it is optimal to buffer the mismatch risk by increasing both the inventory level and the responsive capacity as demand uncertainty increases. In that case, however, both the optimal inventory level and the optimal responsive capacity decrease as the tail of demand becomes heavier. When the profit margin of the product is relatively high, and the cost differential between the suppliers is relatively low, it is optimal to buffer the mismatch risk by increasing the responsive capacity and reducing the inventory level as the demand uncertainty increases. In that case, how¬ever, it is optimal to buffer with more inventory and less capacity as the tail of demand becomes heavier. We also show that the optimal responsive capacity is higher for the products with heavier tails when the fill rate is extremely high.

Warranties used as a mean to promote commercial FOSS

From a business standpoint, this paper describes the point of view on the question of warranties of a FOSS editor doing business in a risk-averse market segment. It is based on 15-years experience of AdaCore in the safety-critical embedded industry. However, it is not only the point of view of a provider, as it also aims at demonstrating that the interests of providers and users are aligned in this area. From a legal point of view, the enforceability of these warranties will be partly covered, as well as the articulation between the license and the warranties on one hand, and the articulation between the license and the other contracts that can be created in a business relationship on the other hand.

Contracting with free software communities

Industry and large Agencies needs ¿agile¿ programming resources, to reinforce their own development staff and take advantage of innovative approaches produced by ¿fresh minds¿ all over the world. At the same time they may be reluctant to engage in classical software development call for tenders and contracts. Such contracts are often ¿trusted¿ by large ICT firms, which will deliver according to their own rigid frameworks (often based on alliances with proprietary software vendors), may propose comfortable quality assurances, but will cover their (real) risks and liability with high contingency costs and will charge for any change request in case the original specifications have not fixed all possible issues. Introducing FLOSS in business implies a new contracting philosophy, based on incentives rather than penalties and liability. Based on 2011 experience with a large Space Agency, Patrice-Emmanuel Schmitz pictures the needed legal instruments for a novel approach.

Sähköasemaprojektoinnin kehittäminen Helsingin Energiassa

Työssä käsitellään Helsingin Energian sähköasemaprojektoinnin kehittämistä. Helsingin kaupunkiolosuhteissa valmiiden ratkaisujen hyödyntäminen ei ole usein mahdollista, vaan asemat on suunniteltava itsenäisinä, erilaisina projekteina. Rakennettavat sähköasemat ovat suuria ja eri osien kilpailuttamisella saavutetaan taloudellista hyötyä. HelenEngineeringillä on mahdollisuus toimia haastavissa projekteissa konsulttimaisena projektinhoitajana. Kun sähköasemaprojektien tarve on jatkuva, Helsingin Energialla on syytä säilyttää oma sähköasemaprojektointiosaaminen. Työtä varten tehtiin haastattelututkimus sähköasemaprojekteja toteuttaville yrityksille ja perehdyttiin kahteen viimeisimpään Helsingin Energialla toteutettuun sähköasemaprojektiin, jotka olivat Viikinmäen 20 kV ja Suvilahden110 kV sähköasemien uusimiset. Näiden perusteella muodostettiin malli toteuttaasähköasemaprojekteja Helsingin Energialla. Malli sisältää muun muassa rungon projektivaiheistukselle, ositukselle, organisaatiokaaviolle, aikataululle ja näkökulmia sopimusten laadintaan. Mallin täysimittainen soveltaminen vaatii kuitenkinjatkuvaa, suunniteltua kehitystyötä. Myös mallia on kehitettävä jatkuvasti.
