Design Guide and Construction Specifications for National Pollutant Discharge Elimination System (NPDES) Site Runoff Control, 2006

According to the 1972 Clean Water Act, the Environmental Protection Agency (EPA) established a set of regulations for the National Pollutant Discharge Elimination System (NPDES). The purpose of these regulations is to reduce pollution of the nation’s waterways. In addition to other pollutants, the NPDES regulates stormwater discharges associated with industrial activities, municipal storm sewer systems, and construction sites. Phase II of the NPDES stormwater regulations, which went into effect in Iowa in 2003, applies to construction activities that disturb more than one acre of ground. The regulations also require certain communities with Municipal Separate Storm Sewer Systems (MS4) to perform education, inspection, and regulation activities to reduce stormwater pollution within their communities. Iowa does not currently have a resource to provide guidance on the stormwater regulations to contractors, designers, engineers, and municipal staff. The Statewide Urban Design and Specifications (SUDAS) manuals are widely accepted as the statewide standard for public improvements. The SUDAS Design manual currently contains a brief chapter (Chapter 7) on erosion and sediment control; however, it is outdated, and Phase II of the NPDES stormwater regulations is not discussed. In response to the need for guidance, this chapter was completely rewritten. It now escribes the need for erosion and sediment control and explains the NPDES stormwater regulations. It provides information for the development and completion of Stormwater Pollution Prevention Plans (SWPPPs) that comply with the stormwater regulations, as well as the proper design and implementation of 28 different erosion and sediment control practices. In addition to the design chapter, this project also updated a section in the SUDAS Specifications manual (Section 9040), which describes the proper materials and methods of construction for the erosion and sediment control practices.

Migrating concepts: Immigrant integration and the regulation of religious dress in France and Canada

Religion in general, and Islam in particular, has become one of the main focal points of policy-making and constitutional politics in many Western liberal states. This article proposes to examine the legal and political dynamics behind new regulations targeting individual religious practices of Muslims. Although one could presuppose that church-state relations or the understanding of secularism is the main factor accounting for either accommodation or prohibition of Muslim religious practices, I make the case that the policy frame used to conceptualize the integration of immigrants in each national context is a more significant influence on how a liberal state approaches the legal regulation of individual practices such as veiling. However, this influence must be assessed carefully since it may have different effects on the different institutional actors in charge of regulating religion, such as the Courts and the legislature. To assess these hypotheses I compare two countries, France and Canada, which are solid examples of two contrasting national policy frames for the integration of immigrants.

Entry regulation and intersectoral reallocation

We study how restrictions on firm entry affect intersectoral factor reallocation when openeconomies experience global economic shocks. In our theoretical framework, countries trade freelyin a range of differentiated sectors that are subject to country-specific and global shocks. Entryrestrictions are modeled as an upper bound on the introduction of new differentiated goods followingshocks. Prices and quantities adjust to clear international goods markets, and wages adjustto clear national labor markets. We show that in general equilibrium, countries with tighter entryrestrictions see less factor reallocation compared to the frictionless benchmark. In our empiricalwork, we compare sectoral employment reallocation across countries in the 1980s and 1990s withproxies for frictionless benchmark reallocation. Our results indicate that the gap between actualand frictionless reallocation is greater in countries where it takes longer to start a firm.

Price regulation of plastic money: A critical assessment of Spanish rules

Recent decisions by the Spanish national competition authority (TDC) mandate paymentsystems to include only two costs when setting their domestic multilateral interchange fees(MIF): a fixed processing cost and a variable cost for the risk of fraud. This artificiallowering of MIFs will not lower consumer prices, because of uncompetitive retailing; but itwill however lead to higher cardholders fees and, likely, new prices for point of saleterminals, delaying the development of the immature Spanish card market. Also, to the extent that increased cardholders fees do not offset the fall in MIFs revenue, the task of issuing new cards will be underpaid relatively to the task of acquiring new merchants, causing an imbalance between the two sides of the networks. Moreover, the pricing scheme arising from the decisions will cause unbundling and underprovision of those services whose costs are excluded. Indeed, the payment guarantee and the free funding period will tend to be removed from the package of services currently provided, to be either provided by third parties, by issuers for a separate fee, or not provided at all, especially to smaller and medium-sized merchants. Transaction services will also suffer the consequences that the TDC precludes pricing them in variable terms.

Market structure and hospital efficiency: Evaluating potential effects of deregulation in a national health service

In this article we examine the potential effect of market structureon hospital technical efficiency as a measure of performance controlled byownership and regulation. This study is relevant to provide an evaluationof the potential effects of recommended and initiated deregulation policiesin order to promote market reforms in the context of a European NationalHealth Service. Our goal was reached through three main empirical stages.Firstly, using patient origin data from hospitals in the region of Cataloniain 1990, we estimated geographic hospital markets through the Elzinga--Hogartyapproach, based on patient flows. Then we measured the market level ofconcentration using the Herfindahl--Hirschman index. Secondly, technicaland scale efficiency scores for each hospital was obtained specifying aData Envelopment Analysis. According to the data nearly two--thirds of thehospitals operate under the production frontier with an average efficiencyscore of 0.841. Finally, the determinants of the efficiency scores wereinvestigated using a censored regression model. Special attention waspaid to test the hypothesis that there is an efficiency improvement in morecompetitive markets. The results suggest that the number of competitors inthe market contributes positively to technical efficiency and there is someevidence that the differences in efficiency scores are attributed toseveral environmental factors such as ownership, market structure andregulation effects.

Mice with an adipocyte-specific lipin 1 separation-of-function allele reveal unexpected roles for phosphatidic acid in metabolic regulation.

Lipin 1 is a coregulator of DNA-bound transcription factors and a phosphatidic acid (PA) phosphatase (PAP) enzyme that catalyzes a critical step in the synthesis of glycerophospholipids. Lipin 1 is highly expressed in adipocytes, and constitutive loss of lipin 1 blocks adipocyte differentiation; however, the effects of Lpin1 deficiency in differentiated adipocytes are unknown. Here we report that adipocyte-specific Lpin1 gene recombination unexpectedly resulted in expression of a truncated lipin 1 protein lacking PAP activity but retaining transcriptional regulatory function. Loss of lipin 1-mediated PAP activity in adipocytes led to reduced glyceride synthesis and increased PA content. Characterization of the deficient mice also revealed that lipin 1 normally modulates cAMP-dependent signaling through protein kinase A to control lipolysis by metabolizing PA, which is an allosteric activator of phosphodiesterase 4 and the molecular target of rapamycin. Consistent with these findings, lipin 1 expression was significantly related to adipose tissue lipolytic rates and protein kinase A signaling in adipose tissue of obese human subjects. Taken together, our findings identify lipin 1 as a reciprocal regulator of triglyceride synthesis and hydrolysis in adipocytes, and suggest that regulation of lipolysis by lipin 1 is mediated by PA-dependent modulation of phosphodiesterase 4.

Tissue-specific opposing functions of the inflammasome adaptor ASC in the regulation of epithelial skin carcinogenesis.

A chronic inflammatory microenvironment favors tumor progression through molecular mechanisms that are still incompletely defined. In inflammation-induced skin cancers, IL-1 receptor- or caspase-1-deficient mice, or mice specifically deficient for the inflammasome adaptor protein ASC (apoptosis-associated speck-like protein containing a CARD) in myeloid cells, had reduced tumor incidence, pointing to a role for IL-1 signaling and inflammasome activation in tumor development. However, mice fully deficient for ASC were not protected, and mice specifically deficient for ASC in keratinocytes developed more tumors than controls, suggesting that, in contrast to its proinflammatory role in myeloid cells, ASC acts as a tumor-suppressor in keratinocytes. Accordingly, ASC protein expression was lost in human cutaneous squamous cell carcinoma, but not in psoriatic skin lesions. Stimulation of primary mouse keratinocytes or the human keratinocyte cell line HaCaT with UVB induced an ASC-dependent phosphorylation of p53 and expression of p53 target genes. In HaCaT cells, ASC interacted with p53 at the endogenous level upon UVB irradiation. Thus, ASC in different tissues may influence tumor growth in opposite directions: it has a proinflammatory role in infiltrating cells that favors tumor development, but it also limits keratinocyte proliferation in response to noxious stimuli, possibly through p53 activation, which helps suppressing tumors.

Neuroligin-1 links neuronal activity to sleep-wake regulation.

Maintaining wakefulness is associated with a progressive increase in the need for sleep. This phenomenon has been linked to changes in synaptic function. The synaptic adhesion molecule Neuroligin-1 (NLG1) controls the activity and synaptic localization of N-methyl-d-aspartate receptors, which activity is impaired by prolonged wakefulness. We here highlight that this pathway may underlie both the adverse effects of sleep loss on cognition and the subsequent changes in cortical synchrony. We found that the expression of specific Nlg1 transcript variants is changed by sleep deprivation in three mouse strains. These observations were associated with strain-specific changes in synaptic NLG1 protein content. Importantly, we showed that Nlg1 knockout mice are not able to sustain wakefulness and spend more time in nonrapid eye movement sleep than wild-type mice. These changes occurred with modifications in waking quality as exemplified by low theta/alpha activity during wakefulness and poor preference for social novelty, as well as altered delta synchrony during sleep. Finally, we identified a transcriptional pathway that could underlie the sleep/wake-dependent changes in Nlg1 expression and that involves clock transcription factors. We thus suggest that NLG1 is an element that contributes to the coupling of neuronal activity to sleep/wake regulation.

The Regulation of Foreign Banks in Switzerland (1956-1972)

The Swiss financial centre witnessed an important shift during the 1960s: the number of foreign banks and their importance in relation to the domestic banking sector significantly increased. Faced with this rapid development, Swiss bank representatives and political and monetary authorities reacted strongly. This paper investigates the evolution of the regulatory response by Swiss banking policy actors to the proliferation of foreign financial in- stitutions. In 1969, those reactions led to the adoption of a discriminatory regime, setting higher entry barriers for foreign banks than for domestic institutions. After examining possible reasons for the attractiveness of Switzerland to foreign banks, this paper will analyse the concerns and fears of the domestic banking sector and its regulators. In this regard, it appears that issues such as mere competition, preservation of the international reputation of the Swiss banks and anti-inflationary monetary policy were central to the chosen regulatory regime. Moreover, this paper shows that foreign banks were used as scapegoats in the evolution of the Swiss system of banking supervision. They were more tightly regulated, yet the general framework remained very lax.

Nitric oxide-induced p53 accumulation and regulation of inducible nitric oxide synthase expression by wild-type p53.

The tumor suppressor gene product p53 plays an important role in the cellular response to DNA damage from exogenous chemical and physical mutagens. Therefore, we hypothesized that p53 performs a similar role in response to putative endogenous mutagens, such as nitric oxide (NO). We report here that exposure of human cells to NO generated from an NO donor or from overexpression of inducible nitric oxide synthase (NOS2) results in p53 protein accumulation. In addition, expression of wild-type (WT) p53 in a variety of human tumor cell lines, as well as murine fibroblasts, results in down-regulation of NOS2 expression through inhibition of the NOS2 promoter. These data are consistent with the hypothesis of a negative feedback loop in which endogenous NO-induced DNA damage results in WT p53 accumulation and provides a novel mechanism by which p53 safeguards against DNA damage through p53-mediated transrepression of NOS2 gene expression, thus reducing the potential for NO-induced DNA damage.

Professional sports and gambling regulation in Finland - Examining the institutional factors of gambling affecting professional sport clubs in Finland

This study examines how to institutional environment of gambling is currently in motion both in Europe and Finland. Furthermore, it examines the criticism by Finnish professional sport clubs directed towards the national gambling monopolies, especially Veikkaus Oy. This criticism addresses the acclaimed issue of low or non-existing sponsorship funds coming to the clubs despite the clubs’ duties to promote Veikkaus Oy in their stadiums etc. In essence the main research objective was to examine the interaction and institutional environments of both Finnish professional sport clubs and gambling regulation. This was done through three sub-objectives: 1) to analyze professional sport as business and its institutional environment 2) to analyze the institutions of gambling in their current state and their potential future 3) to evaluate the potential impact of an institutional change in gambling legislation to the professional sport clubs The findings from Finland were then compared to those of Denmark where an institutional change had occurred in gambling regulation. Empirical data was collected through multiple interviews. Interviewees represented sport clubs (7), sport association (1), sport league (1), Finnish monopoly representatives (2), commercial gambling providers (1), Danish monopoly system representatives (1), Danish sport club (1). In addition a vast amount of secondary data (e.g. Green and white books by EU, court decisions, a variety of studies etc.). Theoretically this study combines the aspects of institutional theory with the theory of professional sports as business. This proved to be a rather new approach and no published literature was found to have done specifically this. The findings of this study are twofold, on the European level it is clear that the momentum if towards a more liberated gambling market while Finland is at the moment trying to go the opposite direction and uphold its monopoly. From the sport club’s level the findings suggest that currently sport clubs do not directly benefit from the funds originated from Veikkaus Oy as these funds are more or less used on the association/league levels. However, the clubs themselves are also lacking in self-criticism as they are lacking in clear sponsorship packages/programs which Veikkaus Oy might be interested in participating. If liberation of the gambling market would occur it is highly possible that that the largest clubs in football and ice-hockey would be the main beneficiaries while smaller clubs and sports could possibly be worse off than currently. These interpretations were well supported by the findings from Denmark.

Fédéralisme, concurrence intergouvernementale et intérêt national dans le domaine des valeurs mobilières au Canada

La structure de la réglementation des valeurs mobilières au Canada fait périodiquement l'objet d'un débat public et une des questions sous-jacentes est celle du partage des compétences législatives prévu par la Constitution canadienne. Le débat a été relancé en 2003 par la recommandation d'un comité de personnes averties de centraliser cette réglementation au fédéral. Les provinces, sauf l'Ontario, demeurent opposées à l'idée, préférant plutôt l'harmonisation réglementaire. Pour alléger le fardeau réglementaire des émetteurs, elles tentent également de mettre en oeuvre un « régime de passeport ». Ce débat présente la question comme un jeu à somme nulle, occultant ainsi certains principes fondamentaux du fédéralisme: innovation provinciale dans une union économique nationale. Dans ce mémoire, nous proposons donc une structure réglementaire, basée sur la théorie de la concurrence intergouvernementale, qui s'harmonise avec les compétences du gouvernement fédéral et des provinces tout en optimisant leurs atouts respectifs.

Enhanced dopamine D2 receptor function in hypothalamus and corpus striatum: their role in liver, plasma and in vitro hepatocyte ALDH regulation in ethahol treated rats

Dopamine D2 receptors are involved in ethanol self- administration behavior and also suggested to mediate the onset and offset of ethanol drinking. In the present study, we investigated dopamine (DA) content and Dopamine D2 (DA D2) receptors in the hypothalamus and corpus striatum of ethanol treated rats and aldehyde dehydrogenase (ALDH) activity in the liver and plasma of ethanol treated rats and in vitro hepatocyte cultures. Hypothalamic and corpus striatal DA content decreased significantly (P\0.05, P\0.001 respectively) and homovanillic acid/ dopamine (HVA/DA) ratio increased significantly (P\0.001) in ethanol treated rats when compared to control. Scatchard analysis of [3H] YM-09151-2 binding to DA D2 receptors in hypothalamus showed a significant increase (P\0.001) in Bmax without any change in Kd in ethanol treated rats compared to control. The Kd of DA D2 receptors significantly decreased (P\0.05) in the corpus striatum of ethanol treated rats when compared to control. DA D2 receptor affinity in the hypothalamus and corpus striatum of control and ethanol treated rats fitted to a single site model with unity as Hill slope value. The in vitro studies on hepatocyte cultures showed that 10-5 M and 10-7 M DA can reverse the increased ALDH activity in 10% ethanol treated cells to near control level. Sulpiride, an antagonist of DA D2, reversed the effect of dopamine on 10% ethanol induced ALDH activity in hepatocytes. Our results showed a decreased dopamine concentration with enhanced DA D2 receptors in the hypothalamus and corpus striatum of ethanol treated rats. Also, increased ALDH was observed in the plasma and liver of ethanol treated rats and in vitro hepatocyte cultures with 10% ethanol as a compensatory mechanism for increased aldehyde production due to increased dopamine metabolism. A decrease in dopamine concentration in major brain regions is coupled with an increase in ALDH activity in liver and plasma, which contributes to the tendency for alcoholism. Since the administration of 10-5 M and 10-7 M DA can reverse the increased ALDH activity in ethanol treated cells to near control level, this has therapeutic application to correct ethanol addicts from addiction due to allergic reaction observed in aldehyde accumulation.

Jmodels: Java models of earth system regulation

The JModel suite consists of a number of models of aspects of the Earth System. They can all be run from the JModels website. They are written in the Java language for maximum portability, and are capable of running on most computing platforms including Windows, MacOS and Unix/Linux. The models are controlled via graphical user interfaces (GUI), so no knowledge of computer programming is required to run them. The models currently available from the JModels website are: Ocean phosphorus cycle Ocean nitrogen and phosphorus cycles Ocean silicon and phosphorus cycles Ocean and atmosphere carbon cycle Energy radiation balance model (under development) The main purpose of the models is to investigate how material and energy cycles of the Earth system are regulated and controlled by different feedbacks. While the central focus is on these feedbacks and Earth System stabilisation, the models can also be used in other ways. These resources have been developed by: National Oceanography Centre, Southampton project led by Toby Tyrrell and Andrew Yool, focus on how the Earth system works.

The national food safety control system of China: a systematic review

In recent years, there have been increasing concerns over the safety of the Chinese food supply. Although many of these have only raised concern internally within China, several major food safety issues have had international repercussions. In response, China has implemented new food safety laws and management systems to improve its national food safety control system and reduce public and international concerns. This paper has describes and discusses the components of the Chinese system using the five key elements of a national food control system identified by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) as essential for an effective system. The latest Chinese national food safety control has made significantly improvement on its regulation framework, however, more work need to be done on standards, law enforcement, and information exchange.
