Southern California small business leaders and emotional intelligence: exploring perceptions of effect and value in the workplace

Although they represent 99.7% of all employers in the American domestic workforce, the annual failure rate of small businesses is alarming. Given this high failure rate, research is needed to better understand the characteristics of leaders who create and sustain success in small businesses. The two-part purpose of this sequential, explanatory mixed-methods study was to (a) measure the emotional intelligence of small business leaders in Southern California and (b) explore the leaders’ perceptions of the effect and value of EI in the workplace. Following the collection of quantitative data using an online version of the Wong and Law Emotional Intelligence Scale (WLEIS) to measure small business leaders’ EI, qualitative data was collected through semi-structured interviews with the study\u27s 12 survey respondents. The interviews were designed to explore the leaders’ perceptions of the effect and value of EI in the workplace. Analysis of the quantitative survey data showed that 75.0% of the leaders rated in the high EI category for the EI total score, and five correlational tendencies (p \u3c .15) were found: higher total EI with having had more leadership positions, self-emotion appraisal score was higher for women and for those with a social sciences background, and older respondents had higher others’ emotion appraisal and regulation of emotion scores. Results from the qualitative analysis suggested that male participants’ EI affects the workplace to a greater extent than that of female participants. Additionally, older participants had higher rates of association between EI workplace effect and others’ emotion appraisal and regulation of emotion. Moreover, those participants who held a higher number of small business leadership positions had greater associations between leader value of EI in the workplace and all four WLEIS scales than those who held fewer leadership positions. Recommendations for future research included comparative studies of different types of professional development programs designed to enhance small business leaders’ EI and further research to better understand how gender moderates the relationship between EI and specific performance outcomes that are known to contribute to overall business success

Luminosity Distributions within Rich Clusters - II: Demonstration and Verification via Simulation

We present detailed simulations of long exposure CCD images. The simulations are used to explore the validity of the statistical method for reconstructing the luminosity distribution of galaxies within a rich cluster i.e. by the subtraction of field number-counts from those of a sight-line through the cluster. In particular we use the simulations to establish the reliability of our observational data presented in Paper 3. Based on our intended CCD field-of-view (6.5 by 6.5 arcmins) and a 1-sigma detection limit of 26 mags per sq arcsecond, we conclude that the luminosity distribution can be robustly determined over a wide range of absolute magnitude (-23 < M_{R} < -16) provided: (a) the cluster has an Abell richness 1.5 or greater, (b) the cluster's redshift lies in the range 0.1 < z < 0.3, (c) the seeing is better than FWHM 1.25'' and (d) the photometric zero points are accurate to within Delta m = \pm 0.12. If these conditions are not met then the recovered luminosity distribution is unreliable and potentially grossly miss-leading. Finally although the method clearly has limitations, within these limitations the technique represents an extremely promising probe of galaxy evolution and environmental dependencies.Comment: 24 pages, 8 figures accepted for publication in MNRAS also available from http://star-www.st-and.ac.uk/~spd3/bib.htm

Long Term Comparison of Alternative Range Livestock Management Strategies Across Extended Droughts and Cyclical Prices

Variable precipitation, more importantly drought, impacts profitability for livestock management. Financial outcomes from management decisions related to forage shortages can be exacerbated by price variability. This research examines alternative management strategies to determine the potential profitability and riskiness over a long-term horizon and across various drought event scenarios. Results indicate that late calving can be a promising strategy, but it also can result in higher variability in profits as compared to some of the other strategies analyzed. Retaining ownership of steer calves over the winter, with the option to sell if forage supplies become scarce, outperforms both partial liquidation and summer feeding, and it results in less profit variability than late calving or early weaning.Production Economics, Productivity Analysis,

A novel profluorescent dinitroxide for imaging polypropylene degradation

Free-radical processes underpin the thermo-oxidative degradation of polyolefins. Thus, to extend the lifetime of these polymers, stabilizers are generally added during processing to scavenge the free radicals formed as the polymer degrades. Nitroxide radical precursors, such as hindered amine stabilizers (HAS),1,2 are common polypropylene additives as the nitroxide moiety is a potent scavenger of polymer alkyl radicals (R¥). Oxidation of HAS by radicals formed during polypropylene degradation yields nitroxide radicals (RRNO¥), which rapidly trap the polymer degradation species to produce alkoxyamines, thus retarding oxidative polymer degradation. This increase in polymer stability is demonstrated by a lengthening of the “induction period” of the polymer (the time prior to a sharp rise in the oxidation of the polymer). Instrumental techniques such as chemiluminescence or infrared spectroscopy are somewhat limited in detecting changes in the polymer during the initial stages of degradation. Therefore, other methods for observing polymer degradation have been sought as the useful life of a polymer does not extend far beyond its “induction period

Comparison of NOAA-9 ERBE measurements with Cirrus IFO satellite and aircraft measurements

Earth Radiation Budget Experiment (ERBE) measurements onboard the NOAA-9 are compared for consistency with satellite and aircraft measurements made during the Cirrus Intensive Field Observation (IFO) of October 1986. ERBE scene identification is compared with NOAA-9 TIROS Operational Vertical Sounder (TOVS) cloud retrievals; results from the ERBE spectral inversion algorithms are compared with High resolution Interferometer Sounder (HIS) measurements; and ERBE radiant existance measurements are compared with aircraft radiative flux measurements

Preventing childhood malaria in Africa by protecting adults from mosquitoes with insecticide-treated nets

Malaria prevention in Africa merits particular attention as the world strives toward a better life for the poorest. Insecticide-treated nets (ITNs) represent a practical means to prevent malaria in Africa, so scaling up coverage to at least 80% of young children and pregnant women by 2010 is integral to the Millennium Development Goals (MDG). Targeting individual protection to vulnerable groups is an accepted priority, but community-level impacts of broader population coverage are largely ignored even though they may be just as important. We therefore estimated coverage thresholds for entire populations at which individual- and community-level protection are equivalent, representing rational targets for ITN coverage beyond vulnerable groups
