Covalently networked monolayer-protected nanoparticle films.

Covalently networked films of nanoparticles can be assembled on various substrates from functionalized monolayer-protected clusters (MPCs) via ester coupling reactions. Exposure of a specifically modified substrate to alternating solutions of 11-mercaptoundecanoic acid exchanged and 11-mercaptoundecanol exchanged MPCs, in the presence of ester coupling reagents, 1,3-dicyclohexylcarbodiimide and 4-(dimethylamino)pyridine, results in the formation of a multilayer film with ester bridges between individual nanoparticles. These films can be grown in a controlled manner to various thicknesses and exhibit certain properties that are consistent with films having other types of interparticle connectivity, including chemical vapor response behavior and quantized double layer charging. Ester coupling of MPCs into assembled films is a straightforward and highly versatile approach that results in robust films that can endure harsher chemical environments than other types of films. The stability of these covalent films is assessed and compared to other more traditional MPC film assemblies.

Economic costs associated with two testing strategies for screening feeder calves for persistent infection with bovine viral diarrhea virus.

OBJECTIVE: To develop partial budgets of the economic costs of 2 test strategies for screening cattle for persistent infection with bovine viral diarrhea virus (BVDV). DESIGN: Partial budget analysis. ANIMALS: 938 calves arriving at 2 stocker operations. PROCEDURE: Calves were tested to determine prevalence of persistent BVDV infection. Test strategies that were evaluated included a single-test strategy consisting of immunohistochemical staining of skin biopsy specimens from all animals and a 2-test strategy consisting of polymerase chain reaction (PCR) assaying of pooled blood samples followed by immunohistochemical staining of skin biopsy specimens from animals in pools for which assay results were positive. Break-even costs (i.e., cost of persistent BVDV infection per animal necessary to justify whole-herd diagnostic testing) associated with each test strategy were calculated as a function of disease prevalence and test cost. RESULTS: Apparent prevalence of persistent BVDV infection was 0.32%. Sensitivity and specificity of the PCR assay for pooled samples were 100% and 89.7%, respectively. Regardless of the prevalence of persistent BVDV infection, the break-even cost for the 2-test strategy was lower than the break-even cost for the single-test strategy. However, the economic advantage was greatest when prevalence was low. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that using a 2-test strategy to screen cattle for persistent BVDV infection, whereby the first test involves PCR assaying of pooled samples and the second involves immunohistochemical testing only of those animals represented in pooled samples with positive assay results, will reduce the cost of screening incoming feedlot cattle, compared with immunohistochemical testing of all animals.

Change the way you persuade.

You call a meeting to try to convince your boss that your company needs to make an important move. Your argument is impassioned, your logic unassailable, your data bulletproof. Two weeks later, though, you learn that your brilliant proposal has been tabled. What went wrong? It's likely the proposal wasn't appropriately geared toward your boss's decision-making style, say consultants Gary Williams and Robert Miller. Over the course of several years' research, the authors have found that executives have a default style of decision making developed early in their careers. That style is reinforced through repeated successes or changed after several failures. Typically, the authors say, executives fall into one of five categories of decision-making styles: Charismatics are intrigued by new ideas, but experience has taught them to make decisions based on balanced information, not just on emotions. Thinkers are risk-averse and need as much data as possible before coming to decisions. Skeptics are suspicious of data that don't fit their worldview and thus make decisions based on their gut feelings. Followers make decisions based on how other trusted executives, or they themselves, have made similar decisions in the past. And controllers focus on the facts and analytics of decisions because of their own fears and uncertainties. But most business presentations aren't designed to acknowledge these different styles--to their detriment. In this article, the authors describe the various subtleties of the five decision-making styles and how best to persuade executives from each group. Knowing executives' preferences for hearing or seeing certain types of information at specific stages in their decision-making process can substantially improve your ability to tip the outcome in your favor, the authors conclude.

Factors related to in-house agricultural animal caseloads in US veterinary teaching hospitals.

A retrospective observational study was conducted to determine whether agricultural animal caseloads at veterinary teaching hospitals declined between 1995 and 1998. Thereafter, the effect of organizational and demographic factors on 1998 in-house agricultural animal caseloads was examined. Caseload data were obtained from the American Association of Veterinary Medical Colleges. Demographic and organizational data were obtained by surveys, telephone interviews, and web-based resources. Complete data were available from 25 veterinary colleges, and data from these schools were used in subsequent analyses. In 1998, in-house food animal caseload decreased relative to 1995 in 17 schools and increased relative to 1995 in 8 schools. This trend was not significant (P = .053); however, the power of the test was limited (.50). Mean 1998 caseload was 886 +/- 504. Among schools with a discipline-based organizational structure, annual mean caseload was 464 +/- 220. Among schools with a species-based organizational structure, mean caseload was 1,167 +/- 463. The regression model that best predicted caseload was a forward-stepping model that included only organizational structure as an independent variable. No additional independent variable was significantly associated with caseload.
