Solarization for the control of Pueraria montana (kudzu)     

CH NEWTON  LR NELSON  SJ DEWALT  EA MIKHAILOVA  CJ POST  MA SCHLAUTMAN  SK COX  WC BRIDGES  KC HALL 《Weed Research》2008,48(5):394-397

The effects of translucent polyethylene sheeting as a thermal covering to eradicate Pueraria montana (kudzu) were investigated at Clemson, South Carolina on a clay loam. In 2005, the highest reduction of live root crowns was observed where P. montana was covered for the entire growing season (May–October) with a reduction of 42% of live root crowns compared with the control plots. Where P. montana was covered for alternate weeks throughout the growing season live root crowns were reduced by 35%. Covering P. montana for one week and then uncovering for four weeks repeatedly through the season killed 24% of root crowns. In 2006, the second year of treatment to the same plots, the three solarization treatments had similar efficacy of about 97%. The use of polyethylene sheeting appears not to be cost‐effective for general control of large P. montana infestations, but may be useful for small patches.  相似文献   

Response of a veterinary college to career development needs identified in the KPMG LLP study and the executive summary of the Brakke study: a combined MBA/DVM program, business certificate program, and curricular modifications

In the present market, veterinarians with a strong background in career development, practice management, and business skills have a clear advantage in achieving financial success. Although there is ample evidence that the scientific and clinical skills of veterinary college graduates are high, there are also data that suggest that additional capabilities in the business realm may promote greater economic success. As noted in the KPMG executive summary, the field of veterinary medicine must make changes in its "current business practices and attitudes" to be successful in the future. Furthermore, the KPMG study found that 36% of industry employers reported that some jobs within their companies had specific job requirements that were not met by a veterinarian with only a veterinary medical degree. The areas of additional training most often cited included business, administration, personnel management, sales and marketing, and financial skills. Yet, Lewis and Klausner found that veterinarians reported challenges in the business realm, such as "how business works and how business goals are translated into action. This challenge held true for veterinarians in industry, academia, government, and private practice." The present gender trends in the field of veterinary medicine provide additional impetus to make career development and business skills training more prevalent. Presently, women comprise >65% of the veterinary student population and approximately 45% of all practicing veterinarians. In some areas of practice, the rate is much higher. For example, in 2002, women comprised 48.2% of all small animal exclusive private practitioners. Unfortunately, the KPMG study found that female veterinarians in private practice report lower self-evaluation of business management and financial skills, compared with their male cohorts. Female veterinarians in nonprivate practice report lower self-evaluation in communication, personnel management, business management, and marketing skills than that reported by males. As a result of these pressing needs, CSU CVMBS has undertaken a major initiative to improve the veterinary practice management and business skills training of veterinary students by offering a variety of options to gain this knowledge: a combined MBA/DVM degree program, a Business Certificate Program for Health Professions, and core curriculum courses. In this way, students can select the amount of focus they want to place on career development and business skills as they earn their DVM degree, to best ensure that they become successful veterinarians.  相似文献

Gender differences and the definition of success: male and female veterinary students' career and work performance expectations     

Kogan LR  McConnell SL  Schoenfeld-Tacher R 《Journal of veterinary medical education》2004,31(2):154-160

This article addresses the challenges that gender performance expectations create within the veterinary profession. An investigation of veterinary students' perceptions of the essential characteristics that define successful veterinarians and veterinary students, and the gender differences within these definitions, is described. Because previous research supports the premise that the standards required for success differ for males and females, it is likely that male and female veterinary students possess different career expectations and definitions of career success. The ramifications of these differences are explored, and proposed strategies to address this issue, in the form of student support services, are discussed.  相似文献   

Photon-induced Kondo satellites in a single-electron transistor     

Kogan A  Amasha S  Kastner MA 《Science (New York, N.Y.)》2004,304(5675):1293-1295

We measure the differential conductance of a single-electron transistor (SET) irradiated with microwaves. The spin-entangled many-electron Kondo state produces a zero-bias peak in the dc differential conductance if the quantum dot in the SET contains an unpaired electron. When the photon energy hf is comparable to the energy width of the Kondo peak and to e (the charge on the electron) times the microwave voltage across the dot, satellites appear in the differential conductance shifted in voltage by +/-hf/e from the zero-bias resonance. We also observe an overall suppression of the Kondo features with increasing microwave voltage.  相似文献
