Discernible Differences (discernible + difference)
Selected AbstractsEthical Attitudes in Small Businesses and Large Corporations: Theory and Empirical Findings from a Tracking Study Spanning Three DecadesJOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 2 2006Justin G. Longenecker This study offers a theoretical framework of ethical behavior and a comparative analysis of ethical perceptions of managers of large, mostly publicly traded corporations (those with 1,000 or more employees) and the owners and managers of smaller companies (those with fewer than 100 employees) across 17 years. The primary research provides basic data on the changing standards of ethics as perceived by leaders of large and small businesses where the cultures frequently fall into sharp contrast. Our findings reveal the extent to which the message of business integrity is gaining or losing ground within large and small companies. It does this by means of respondents' judgments of acceptable responses to 16 scenarios profiling common business situations with questionable ethical dimensions. Based on responses from over 5,000 managers and employees (from firms of all sizes) to our scenarios at three points in time (1985, 1993, 2001), we tested two research questions. First, for firms of all sizes, have business ethics improved or declined between the years 1985 and 2001? Second, comparing responses of large and small firm executives across the 1985,2001 time frame, is there a discernible difference in their ethical standards? Our results suggest that business leaders are making somewhat more ethical decisions in recent years. We also found that small business owner,managers offered less ethical responses to scenarios in 1993 but that no significant differences existed with large firm managers in 1985 and 2001. Implications of our findings are discussed. [source] Better land husbandry in Honduras: towards the new paradigm in conserving soil, water and productivityLAND DEGRADATION AND DEVELOPMENT, Issue 3 2002J. Hellin Abstract Land shortages are forcing more smallholder farmers to cultivate tropical steeplands. Resulting accelerated soil erosion is being countered by the promotion of soil conservation (SC) technologies, such as cross-slope barriers, which aim to reduce soil loss and preserve land productivity. However, farmer adoption rates tend to be low. This is often attributed to the farmers' conservatism or lack of education. Research in Honduras's steeplands demonstrates that farmers value SC, provided that it promotes agricultural production. Field research from 1995,98, involving farmed test plots on slopes greater than 35 per cent (19 degrees), demonstrates that at least one typical SC technology,live barriers of Vetiveria zizanioides (vetiver grass),has little or no impact on maize yield. This means that farmers see little benefit from their investment in the SC method. They find that erratic rainfall, pests and diseases and a lack of economic resources are far greater threats to their livelihoods than soil erosion. Consequently, SC has a low priority. Keeping soil in place avoids major off-farm disbenefits. However, the SC technique tested here made no discernible difference to slope foot sediment yields during the life of this study. In sum, a new approach is needed. Promoting ,Better Land Husbandry' strategies, which seek to combine farmers' concerns about productivity with conservationists' concerns about reducing soil erosion,often via cover-management,seem to be the best way forward.

[source] Divided justice, different voices: inheritance and family provisionLEGAL STUDIES, Issue 4 2003Fiona Cownie Both the Family Division of the High Court and the Chancery Division of the High Court exercise jurisdiction over the Inheritance (Provision for Family and Dependents) Act 1975, with the applicant being able to elect the Division that they wish to proceed in. Many practitioners believe that the two Divisions have different attitudes towards the Act. This paper argues the structure of the 1975 Act makes it highly likely that the two Divisions will approach in different ways and that a close analysis of judgments shows that there is a discernible difference in the rhetoric that is used in judgments in the two Divisions, that this difference in rhetoric affects the way in which applicants are viewed and that thus sometimes it affects the outcome of cases. Since there is no advantage in practice to having the two jurisdictions and since the difference between the jurisprudences in the two Divisions can result in like cases not being treated alike, an elementary form of injustice. The paper concludes that it would be better if one Division exercised sole jurisdiction over the Act. [source] Improvement of Postfractional Laser Erythema with Light-Emitting Diode PhotomodulationDERMATOLOGIC SURGERY, Issue 5 2009TINA S. ALSTER MD BACKGROUND The most common side effects of fractional laser skin treatment are erythema and edema. Low-level light therapy and light-emitting diode (LED) devices have been used to stimulate fibroblast activity and hasten wound healing. OBJECTIVE To determine whether LED treatment immediately after fractional laser skin resurfacing affects the severity and duration of postoperative eythema. MATERIALS AND METHODS Twenty patients received treatment with a 590-nm wavelength LED array to randomly selected facial halves immediately after undergoing full-face fractional laser skin resurfacing with a 1,550-nm erbium-doped fiber laser. Differences in erythema between LED-treated and untreated facial halves were recorded at 24, 48, and 96 hours post-treatment. RESULTS The LED-treated facial halves were less erythematous in all 20 patients 24 hours postoperatively. The six patients who received the highest mean energy densities during fractional laser treatment continued to exhibit decreased erythema in the LED-treated areas at 48 hours. At 96 hours post-treatment, no discernible differences between facial halves were observed in any patient. CONCLUSIONS Photomodulation with a 590-nm-wavelength LED array can decrease the intensity and duration of postfractional laser treatment erythema. [source] Critical role for retinol in the generation/differentiation of angioblasts required for embryonic blood vessel formation,DEVELOPMENTAL DYNAMICS, Issue 4 2004Amanda C. LaRue Abstract Numerous studies demonstrate that vitamin A (retinol) deficiency causes abnormal cardiovascular morphogenesis. We evaluated the impact of retinol deficiency on the regulation of the numbers of endothelial cells and angioblasts (endothelial progenitors) produced during embryonic quail development. At the one-somite stage, there were no discernible differences in the mean number of endothelial cells or angioblasts in normal and retinol-deficient embryos. However, retinol-deficient embryos at the three-somite stage had an increase in the mean number of endothelial cells but no difference in the mean number of angioblasts. By contrast, retinol-deficient embryos at the five-somite stage have 61% of the normal number of endothelial cells and 12% of the normal number of angioblasts. Similarly, retinol-deficient embryos at the 10-somite stage had 71% and 60% of normal numbers of endothelial cells in capillary-like networks and the sinuses venosus, respectively. Furthermore, we show that retinol deficiency did not elicit a global reduction in mesodermal cell numbers but was specific to cells of the endothelial lineage. Taken together, our findings suggest that vascular abnormalities observed under conditions of retinol deficiency are due to reduction in the number of angioblasts and consequently an insufficiency in the number of endothelial cells required to build complex vascular networks.

White Abstract Aim To explore the beliefs, attitudes and perceptions of adults with Type 2 diabetes and their family members. Methods Focus groups were conducted with: (i) people with good diabetes control (HbA1c < 7.0%); (ii) their family members; (iii) people with poor diabetes control (HbA1c > 8.5%); and (iv) their family members. Results There were no discernible differences between those with good and poor diabetes control or between the family members of each group. Overall, family members perceived diabetes to be more serious and as having a greater impact on daily life than those with the illness. Those with diabetes were unaware of this heightened concern and had a more relaxed approach to living with diabetes. The lack of information and perceived knowledge about diabetes impacted upon participants' causal attributions about the illness and its perceived severity. Conclusions Diabetes is an illness that affects both individuals and families. There is a need for further investigation into the impact that family members have on the management of diabetes. [source] Simulated rainfall evaluation of revegetation/mulch erosion control in the Lake Tahoe Basin,1: method assessmentLAND DEGRADATION AND DEVELOPMENT, Issue 6 2004M. E. Grismer Abstract Revegetation of road cuts and fills is intended to stabilize those drastically disturbed areas so that sediment is not transported to adjacent waterways. Sediment has resulted in water quality degradation, an extremely critical issue in the Lake Tahoe Basin. Many revegetation efforts in this semiarid, subalpine environment have resulted in low levels of plant cover, thus failing to meet project goals. Further, no adequate physical method of assessing project effectiveness has been developed, relative to runoff or sediment movement. This paper describes the use of a portable rainfall simulator (RS) to conduct a preliminary assessment of the effectiveness of a variety of erosion-control treatments and treatment effects on hydrologic parameters and erosion. The particular goal of this paper is to determine whether the RS method can measure revegetation treatment effects on infiltration and erosion. The RS-plot studies were used to determine slope, cover (mulch and vegetation) and surface roughness effects on infiltration, runoff and erosion rates at several roadcuts across the basin. A rainfall rate of ,60,mm,h,1, approximating the 100-yr, 15-min design storm, was applied over replicated 0·64,m2 plots in each treatment type and over bare-soil plots for comparison. Simulated rainfall had a mean drop size of ,2·1,mm and approximately 70% of ,natural' kinetic energy. Measured parameters included time to runoff, infiltration, runoff/infiltration rate, sediment discharge rate and average sediment concentration as well as analysis of total Kjeldahl nitrogen (TKN) and dissolved phosphorus (TDP) from filtered (0·45,,m) runoff samples. Runoff rates, sediment concentrations and yields were greater from volcanic soils as compared to that from granitic soils for nearly all cover conditions. For example, bare soil sediment yields from volcanic soils ranged from 2,12 as compared to 0·3,3,g,m,2,mm,1 for granitic soils. Pine-needle mulch cover treatments substantially reduced sediment yields from all plots. Plot microtopography or roughness and cross-slope had no effect on sediment concentrations in runoff or sediment yield. RS measurements showed discernible differences in runoff, infiltration, and sediment yields between treatments. Runoff nutrient concentrations were not distinguishable from that in the rainwater used. Copyright © 2004 John Wiley & Sons, Ltd. [source] Hormonal Response of Female Goats to Active Immunization against a Recombinant Human Inhibin ,-subunit, and establishment of an Enzyme-linked Immunosorbent Assay for Caprine Follicle-stimulating HormoneREPRODUCTION IN DOMESTIC ANIMALS, Issue 2 2001M Hennies The effect of selective immunosuppression of endogenous inhibin in goats on FSH, LH, progesterone and estradiol-17, profiles was studied during the breeding and nonbreeding seasons. Eighteen adult female Boer goats were immunized against the recombinant human inhibin ,-subunit (hINH-,). With the exception of estradiol, which was determined by radio-immunoassay (RIA), all plasma hormone concentrations were determined by ELISA. The ELISA for FSH presented in this paper was established in the authors' laboratory, based on an existing RIA. Mean basal concentrations of FSH were not affected by immunosuppression of endogenous inhibin, nor was there a difference in the amplitude of the pre-ovulatory FSH surge. Immunization against inhibin appears to eliminate the slight secondary rise of FSH occurring 12,20 h after the major surge associated with ovulation. The LH profiles of the immunized goats were characterized by lower basal concentrations both before and after the pre-ovulatory LH surge which itself was reduced by 50% in immunized does. By contrast, concentrations of circulating estradiol were significantly elevated after inhibin-immunization. Progesterone profiles were not affected. Extending immunization into the anoestrous season by a booster injection of hINH-,, implicating oestrus induction with a progestagen and eCG, produced no discernible differences in FSH and LH profiles in comparison with nonimmunized control goats. The findings suggest that in goats, paracrine factors may play a more significant role in controlling follicular activity than a feedback mechanism acting via the pituitary. [source] | ||||||||||
