Now You See it, Now You Don't: Why Do Real Estate Agents Withhold Available Houses from Black Customers?

Potential home buyers may initiate contact with a real estate agent by asking to see a particular advertised house. This paper asks whether an agent's response to such a request depends on the race of the potential buyer or on whether the house is located in an integrated neighborhood. We build on previous research about the causes of discrimination in housing by using data from fair housing audits, a matched-pair technique for comparing the treatment of equllay qualified black and white home buyers. However, we shift the focus from differences in the treatment of paired buyers to agent decisions concerning an individual housing unit using a sample of all houses seen during he 1989 Housing Discrimination study. We estimate a random effect, multinomial logit model to explain a real estate agent's joint decisions concerning whether to show each unit to a black auditor and to a white auditor. We find evidence that agents withhold houses in suburban, integrated neighborhoods from all customers (redlining), that agents' decisions to show houses in integrated neighborhoods are not the same for black and white customers (steering), and that the houses agents show are more likely to deviate from the initial request when the customeris black than when the customer is white. These deviations are consistent with the possibility that agents act upon the belief that some types of transactions are relatively unlikely for black customers (statistical discrimination).

Property Condition Disclosure Law: Why Did States Mandate 'Seller Tell All'?

Thirty-six US states have already enacted some form of seller's property condition disclosure law. At a time when there is a movement in this direction nationally, this paper attempts to ascertain the factors that lead states to adopt disclosure law. Motivation for the study stems from the fact that not all states have yet adopted the law, and states that have enacted the law have done so in different years. The analytical structure employs hazard models, using a unique set of economic and institutional attributes for a panel of 50 US States spanning 21 years, from 1984 to 2004. The proportional hazard analysis of law adoption reveals that greater number of disciplinary actions tends to favor passage of the law. Greater broker supervision, implying generally higher awareness among real estate agents, seems to have a negative impact on the likelihood of a state adopting a property condition disclosure law.

Why does low dose morphine augment fentanyl analgesia?

Opioids dominate the field of pain management because of their ability to provide analgesia in many medical circumstances. However, side effects including respiratory depression, constipation, tolerance, physical dependence, and the risk of addiction limit their clinical utility. Fear of these side effects results in the under-treatment of acute pain. For many years, research has focused on ways to improve the therapeutic index (the ratio of desirable analgesic effects to undesirable side effects) of opioids. One strategy, combining opioid agonists that bind to different opioid receptor types, may prove successful.^ We discovered that subcutaneous co-administration of a moderately analgesic dose of the mu-opioid receptor (MOR) selective agonist fentanyl (20μg/kg) with subanalgesic doses of the less MOR-specific agonist morphine (100ng/kg-100μg/kg), augmented acute fentanyl analgesia in rats. Parallel [35S]GTPγS binding studies using naïve rat substantia gelatinosa membrane treated with fentanyl (4μM) and morphine (1nM-1pM) demonstrated a 2-fold increase in total G-protein activation. This correlation between morphine-induced augmentation of fentanyl analgesia and G-protein activation led to our proposal that interactions between MORs and DORs underlie opioid-induced augmentation. We discovered that morphine-induced augmentation of fentanyl analgesia and G-protein activity was mediated by DORs. Adding the DOR-selective antagonist naltrindole (200ng/kg, 40nM) at doses that did not alter the analgesic or G-protein activation of fentanyl, blocked increases in analgesia and G-protein activation induced by fentanyl/morphine combinations. Equivalent doses of the MOR-selective antagonist cyprodime (20ng/kg, 4nM) did not block augmentation. Substitution of the DOR-selective agonist SNC80 for morphine yielded similar results, further supporting our conclusion that interactions between MORs and DORs are responsible for morphine-induced augmentation of fentanyl analgesia and G-protein activation. Confocal microscopy of rat substantia gelatinosa showed that changes in the rate of opioid receptor internalization did not account for these effects.^ In conclusion, fentanyl analgesia augmentation by subanalgesic morphine is mediated by increased G-protein activation resulting from functional interactions between MORs and DORs, not changes in MOR internalization. Additional animal and clinical studies are needed to determine whether side effect incidence changes following opioid co-administration. If side effect incidence decreases or remains unchanged, these findings could have important implications for clinical pain treatment. ^

Why is asthma mortality higher in Puerto Ricans?

Asthma is a significant public health issue and the most common chronic disease in children. The disease burden of asthma is rising around the world and especially in certain populations. In the United States Puerto Rican Americans have the highest rates of mortality due to asthma, while Mexico Americans have the lowest asthma mortality in the U.S. The reasons for this have been the cause of much speculation in the past; however, no clear cause for these differences has been recognized. The present work reviews the literature bearing on this question to show that there are good reasons to believe that individuals with unusually responsive innate immune responses may be predisposed to the development of asthma. Also reviewed is the molecular basis for this connection. The evidence shows that the history and anthropology of the Puerto Rican people is quite different from that of any other surviving North American or Caribbean population, as it was a relatively isolated island population for 400 years with an environment that tended to eliminate individuals with weak innate immune systems. The Puerto Rican population successfully survived the Columbian exchange of microbes but may be poorly adapted to the modern pro-inflammatory diet coupled with exposure to cigarette smoke as well as cockroach and house dust mite feces.^

A critical review: Why isn't "cold pasteurization" being used widespread as a method to prevent food-related illnesses as a result of the consumption of ready-to-eat, fresh fruits, and vegetables

The Centers for Disease Control estimates that foodborne diseases cause approximately 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States each year. The American public is becoming more health conscious and there has been an increase in the dietary intake of fresh fruits and vegetables. Affluence and demand for convenience has allowed consumers to opt for pre-processed packaged fresh fruits and vegetables. These pre-processed foods are considered Ready-to-Eat. They have many of the advantages of fresh produce without the inconvenience of processing at home. After seeing a decline in food-related illnesses between 1996 and 2004, due to an improvement in meat and poultry safety, tainted produce has tilted the numbers back. This has resulted in none of the Healthy People 2010 targets for food-related illness reduction being reached. Irradiation has been shown to be effective in eliminating many of the foodborne pathogens. The application of irradiation as a food safety treatment has been widely endorsed by many of the major associations involved with food safety and public health. Despite these endorsements there has been very little use of this technology to date for reducing the disease burden associated with the consumption of these products. A review of the available literature since the passage of the 1996 Food Quality Protection Act was conducted on the barriers to implementing irradiation as a food safety process for fresh fruits and vegetables. The impediments to adopting widespread utilization of irradiation food processing as a food safety measure involve a complex array of legislative, regulatory, industry, and consumer issues. The FDA’s approval process limits the expansion of the list of foods approved for the application of irradiation as a food safety process. There is also a lack of capacity within the industry to meet the needs of a geographically dispersed industry.^

Why the Village is so Hard to Find: Challenging Ourselves, Transforming Our Helping Systems

Keynote address presented by Roger Friedman, PhD, LCSW at the Family Preservation Institute Annual Conference, San Antonio, Texas, September 9, 2004. Looking at Language and Concepts Looking closely at certain language that we use helps us understand how we think about our work and our world—and ultimately, it helps us understand ourselves better. The term "village " as used in the title of the paper and in many of our professional conversations is worthy of such an inquiry

“Dishonourable disobedience” – Why refusal to treat in reproductive healthcare is not conscientious objection

In medicine, the vast majority of conscientious objection (CO) is exercised within the reproductive healthcare field – particularly for abortion and contraception. Current laws and practices in various countries around CO in reproductive healthcare show that it is unworkable and frequently abused, with harmful impacts on women's healthcare and rights. CO in medicine is supposedly analogous to CO in the military, but in fact the two have little in common. This paper argues that CO in reproductive health is not actually Conscientious Objection, but Dishonourable Disobedience (DD) to laws and ethical codes. Healthcare professionals who exercise CO are using their position of trust and authority to impose their personal beliefs on patients, who are completely dependent on them for essential healthcare. Health systems and institutions that prohibit staff from providing abortion or contraception services are being discriminatory by systematically denying healthcare services to a vulnerable population and disregarding conscience rights for abortion providers. CO in reproductive healthcare should be dealt with like any other failure to perform one's professional duty, through enforcement and disciplinary measures. Counteracting institutional CO may require governmental or even international intervention.

Why Do Economies Enter into Preferential Agreements on Trade in Services? Assessing the Potential for Negotiated Regulatory Convergence in Asian Services Markets

More than one-third of the World Trade Organization-notified services trade agreements that were in effect between January 2008 and August 2015 involved at least one South or Southeast Asian trading partner. Drawing on Baier and Bergstrand’s (2004) determinants of preferential trade agreements and using the World Bank’s database on the restrictiveness of domestic services regimes (Borchert, Gootiiz, and Mattoo 2012), we examine the potential for negotiated regulatory convergence in Asian services markets. Our results suggest that Asian economies with high levels of preexisting bilateral merchandise trade and wide differences in services regulatory frameworks are more likely candidates for services trade agreement formation. Such results lend support to the hypothesis that the heightened “servicification” of production generates demand for the lowered services input costs resulting from negotiated market openings.

Why do Countries Enter into Preferential Agreements on Trade in Services? Assessing the Potential for Negotiated Regulatory Convergence in Asian Services Markets

More than a third of the World Trade Organization (WTO)-notified services trade agreements (STAs) in effect over January 2008 - August 2015 have involved at least one (South or Southeast) Asian trading partner. Drawing on Baier and Bergstrand's (2004) determinants of preferential trade agreements and using the World Bank's database on the restrictiveness of domestic services regimes (Borchert et.al. 2012), we examine the potential for negotiated regulatory convergence in Asian services markets. Our results suggest that countries within Asia with high levels of pre-existing bilateral merchandise trade and wide differences in services regulatory frameworks are more likely candidates for STA formation. Such results lend support to the hypothesis that the heightened "servicification" of production generates a demand for the lowered service input costs resulting from negotiated market opening.

Policy forums: Why do they exist and what are they used for?

Policy forums are issue-based intermediary organizations where diverse types of political and societal actors repeatedly interact. Policy forums are important elements of modern governance systems as they allow actors to learn, negotiate, or build trust. They can vary in composition, size, membership logic, and other distinct features. This article lays the foundation of a theory of policy forums based on three interrelated elements: First, it discusses conditions for the formation of a forum and describes the logic of these organizations as one of an asymmetric multipartite exchange. Second, it enumerates the potential set of goals and motivations of participating actors that are fed into this exchange. Third, it proposes eight different dimensions on which policy forums differ and which affect the exchange mechanisms among actors. We claim that empirical work on policy forums should systematically take these elements into account and propose elements of a research agenda.

Trade, Exchange Rates, and Macroeconomic Dynamics in East Asia: Why the Electronics Cycle Matters

Against the background of increasing regional trade and investment, there is growing interest in monetary and macroeconomic policy coordination in East Asia. Although there is a sizable literature on macroeconomic linkages among East Asian countries and the potential merit of policy coordination in the region, the existing studies tend to examine these issues exclusively in terms of macroeconomic variables and do not consider how these aggregate variables are influenced by one prominent feature of a number of East Asian economies: their heavy dependence on the electronics industry. Although active engagement in the global electronics industry has been a powerful growth engine for the Asian countries, it has also left their economies vulnerable to cyclical fluctuations in the world electronics market. As the cycle of the global electronics industry exerts profound impacts on the medium-term dynamics of the Asian economies, it is imperative to take an explicit account of its influence when studying the way in which the regional economies are linked to one another and how this relationship can be altered by a specific policy initiative. We illustrate the importance of this point by examining recent studies on: (1) trade competition between China andother Asian countries and the role of the Chinese renminbi therein; and (2) the effect offluctuations in the yen/dollar exchange rate on the regional economies.
