Selected AbstractsHAS WAL-MART BURIED MOM AND POP?: THE IMPACT OF WAL-MART ON SELF-EMPLOYMENT AND SMALL ESTABLISHMENTS IN THE UNITED STATESECONOMIC INQUIRY, Issue 4 2008RUSSELL S. SOBEL This paper explores the widely accepted view that Wal-Mart causes significant harm to the traditional, small "mom and pop" business sector of the U.S. economy. We present the first rigorous econometric investigation of this issue by examining the rate of self-employment and the number of small employer establishments using both time series and cross-sectional data. We also examine alternative measures and empirical techniques for robustness. Contrary to popular belief, our results suggest that the process of creative destruction unleashed by Wal-Mart has had no statistically significant long-run impact on the overall size and profitability of the small business sector in the United States.

Lindsay M.D. Since the 1997 National Institutes of Health Consensus Development Conference on management of hepatitis C there have been several important advances that significantly impact its therapy; notably the availability of sensitive, specific, and standardized assays for identifying hepatitis C virus (HCV) RNA in the serum, the addition of ribavirin to alpha interferon, the pegylation of alpha interferon, and the demonstration that sustained virological response (SVR) is the optimal surrogate endpoint of treatment. Using pegylated interferon and ribavirin, virological response with relapse and nonresponse are less common, but remain poorly understood. Current studies are evaluating nonvirological endpoints of treatment, namely biochemical response and histological response. To date, definitive treatment trials have primarily been conducted in adult patients with elevated aminotransferase levels, clinically compensated chronic liver disease, and no other significant medical disorder. Limited data are available from studies of other patient populations, and the safety of interferon-based treatment has not yet been established in several patient groups. Future research is needed to elucidate the mechanisms of viral response and clearance, to develop effective therapies for interferon nonresponse or intolerance, to define the role of complementary and alternative medicine and other nonspecific therapies, and to develop strategies for the optimal management and treatment of special patient populations who probably represent the majority of persons with chronic hepatitis C in the United States.

Ferraro Failure to consider costs as well as benefits is common in many policy initiatives and analyses, particularly in the environmental arena. Economists and other policy scientists have demonstrated that integrating both cost and benefit information explicitly into the policy process can be vital to ensuring that scarce funds go as far as they can toward achieving policy objectives. The costs of acquiring and analyzing such information, however, can be substantial. The objective of this paper is to help policy analysts and practitioners identify the conditions under which integrating cost and benefit information is likely to be vital to effective decisionmaking, and the conditions under which failing to use both cost and benefit data would result in little, if any, loss in efficiency. These points are illustrated through a conceptual discussion and an empirical analysis of a conservation initiative in the United States. © 2003 by the Association for Public Policy Analysis and Management. [source] Effecting science, affecting medicine: Homosexuality, the Kinsey reports, and the contested boundaries of psychopathology in the United States, 1948,1965JOURNAL OF THE HISTORY OF THE BEHAVIORAL SCIENCES, Issue 4 2008Howard Hsueh-Hao Chiang Despite the well-documented intensive battle between Alfred Kinsey and American psychiatrists around the mid-twentieth century, this paper argues that Kinsey's work, in fact, played a significant role in transforming mental health experts' view of homosexuality starting as far back as the late 1940s and extending all the way through the mid-1960s. After analyzing the way in which Kinsey's work pushed American psychiatrists to re-evaluate their understanding of homosexuality indirectly through the effort of clinical psychologists, I then focus to a greater extent on examples that illustrate how the Kinsey reports directly influenced members of the psychiatric community. In the conclusion, using a Foucauldian conception of "discourse," I propose that in order to approach the struggle around the pathological status of homosexuality in the 1950s and the 1960s, thinking in terms of a "politics of knowledge" is more promising than simply in terms of a "politics of diagnosis." Central to the struggle was not merely the matter of medical diagnosis, but larger issues regarding the production of knowledge at an intersection of science and medicine where the parameters of psychopathology were disputed in the context of mid-twentieth-century United States. © 2008 Wiley Periodicals, Inc. [source] DSM-III and the revolution in the classification of mental illnessJOURNAL OF THE HISTORY OF THE BEHAVIORAL SCIENCES, Issue 3 2005Rick Mayes A revolution occurred within the psychiatric profession in the early 1980s that rapidly transformed the theory and practice of mental health in the United States. In a very short period of time, mental illnesses were transformed from broad, etiologically defined entities that were continuous with normality to symptom-based, categorical diseases. The third edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-III) was responsible for this change. The paradigm shift in mental health diagnosis in the DSM-III was neither a product of growing scientific knowledge nor of increasing medicalization. Instead, its symptom-based diagnoses reflect a growing standardization of psychiatric diagnoses. This standardization was the product of many factors, including: (1) professional politics within the mental health community, (2) increased government involvement in mental health research and policymaking, (3) mounting pressure on psychiatrists from health insurers to demonstrate the effectiveness of their practices, and (4) the necessity of pharmaceutical companies to market their products to treat specific diseases. This article endeavors to explain the origins of DSM-III, the political struggles that generated it, and its long-term consequences for clinical diagnosis and treatment of mental disorders in the United States. © 2005 Wiley Periodicals, Inc. [source] Language preference and its relationship with reading skills in English and SpanishPSYCHOLOGY IN THE SCHOOLS, Issue 2 2007Michele H. Brenneman A dearth of research has investigated the language preference of bilingual childhood populations and its subsequent relationship to reading skills. The current study evaluated how a sequential bilingual student's choice of language, in a particular environmental context, predicted reading ability in English and Spanish. The participants were Latino children ranging in age from 7 years, 5 months, to 11 years, 6 months, with 43% born in the United States. Results showed a relationship between a child's higher English language preference for media and for communication with others outside the family and better reading skills in English. Language preference differences predicted reading abilities better for English than for Spanish. Results suggested that sequential bilingual children's language preference may be a useful marker of English language (second language [L2]) facility and use that is related to their reading proficiency or influences the development of English reading skills in such bilingual children in the United States. © 2007 Wiley Periodicals, Inc.

[source] Clinical Practice Guidelines for the Use of Axillary Sentinel Lymph Node Biopsy in Carcinoma of the Breast: Current UpdateTHE BREAST JOURNAL, Issue 2 2004Gordon F. Schwartz MD, MBAArticle first published online: 10 MAR 200 Abstract: Axillary sentinel lymph node biopsy (SLNB) has been adopted as a suitable alternative to traditional level I and II axillary dissection in the management of clinically node-negative (N0) breast cancers. There are two current techniques used to identify the sentinel node(s): radiopharmaceutical, technetium sulfur colloid, and isosulfan blue dye (used in the United States) and technetium-labeled albumin and patent blue dye (used in Europe). (The labeled albumin is not U.S. Food and Drug Administration [FDA] approved in the United States.) SLNB to replace axillary dissection should only be performed by surgeons and patient management teams with appropriate training and experience. Although both radiocolloid and blue dye are used together by most surgeons, and training should be in both techniques, some experienced surgeons use one or the other almost exclusively. In addition, surgical pathologists must recognize the need to examine these small specimens with great care, using a generally adopted protocol. Imprint cytology or frozen sections may be used, followed by additional sections for light microscopy. Immunochemical staining with cytokeratin or other techniques to identify "submicroscopic" metastasis is often used, but the results should not be used to influence clinical decisions with respect to adjuvant therapy. "Failed" SLNB implies the surgeon's failure to identify the sentinel nodes, in which case a complete dissection is performed. A "false-negative" SLNB implies the finding of metastasis in the excised sentinel nodes by light microscopy after a negative frozen section examination. Whether a false-negative SLNB mandates completion axillary dissection is controversial, with clinical trials currently under way to answer this question. Although SLNB was initiated to accompany breast-conserving treatment, it is equally useful in patients undergoing mastectomy. It is more difficult to perform with mastectomy. When using blue dye only, SLNB may require a separate incision because of time constraints between injection and identification of the blue-stained nodes; radiocolloid usually does not. Completion axillary dissection after false-negative SLNB is more difficult after mastectomy. SLNB is a useful procedure that may save 70% of women with clinically negative (N0) axillae and all of those with pathologically negative axillae from the morbidity of complete axillary dissection. Ideally the sentinel nodes should be able to identified in more than 95% of patients, with a false-negative rate of less than 5%. Until these rates can be achieved consistently, however, surgeons should not abandon traditional axillary dissection., [source] A Hallucinogenic Tea, Laced with Controversy: Ayahuasca in the Amazon and the United States. by Marlene Dobkin de Rios and Roger RumrrillANTHROPOLOGY OF CONSCIOUSNESS, Issue 1 2010John R.

[source] Widespread distribution of knockdown resistance mutations in the bed bug, Cimex lectularius (Hemiptera: Cimicidae), populations in the United StatesARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY (ELECTRONIC), Issue 4 2010Fang Zhu Abstract We previously reported high deltamethrin resistance in bed bugs, Cimex lectularius, collected from multiple areas of the United States (Romero et al., 2007). Recently, two mutations, the Valine to Leucine mutation (V419L) and the Leucine to Isoleucine mutation (L925I) in voltage-gated sodium channel ,-subunit gene, had been identified to be responsible for knockdown resistance (kdr) to deltamethrin in bed bugs collected from New York (Yoon et al., 2008). The current study was undertaken to investigate the distribution of these two kdr mutations in 110 bed bug populations collected in the United States. Out of the 17 bed bug populations that were assayed for deltamethrin susceptibility, two resistant populations collected in the Cincinnati area and three deltamethrin-susceptible lab colonies showed neither of the two reported mutations (haplotype A). The remaining 12 populations contained L925I or both V419L and L925I mutations in voltage-gated sodium channel ,-subunit gene (haplotypes B&C). In 93 populations that were not assayed for deltamethrin susceptibility, 12 contained neither of the two mutations (haplotype A) and 81 contained L925I or V419L or both mutations (haplotypes B-D). Thus, 88% of the bed bug populations collected showed target-site mutations. These data suggest that deltamethrin resistance conferred by target-site insensitivity of sodium channel is widely spread in bed bug populations across the United States. © 2010 Wiley Periodicals, Inc.
