Guest Editors' introduction: philosophical contributions to leadership ethics

This article introduces the first of two special issues on philosophical approaches to leadership ethics. In it, we show some of the ways that philosophy contributes to the study of leadership and leadership ethics. We begin with an overview of how philosophers have treated some of the ethical aspects and challenges of leadership. These include discussions of self interest, the problem of dirty hands, responsibility, moral luck, power, gender and diversity, and spirituality. The articles in this issue draw on philosophy to explore a variety of ethical questions related to leadership and the relationships that leaders have with followers and others

Experimental Resonance Enhanced Multiphoton Ionization (REMPI) studies of small molecules

Resonance enhanced multiphoton ionization (REMPI) utilizes tunable dye lasers to ionize an atom or molecule by first preparing an excited state by multiphoton absorption and then ionizing that state before it can decay. This process is highly selective with respect to both the initial and resonant intermediate states of the target, and it can be extremely sensitive. In addition, the products of the REMPI process can be detected as needed by analyzing the resulting electrons, ions, fluorescence, or by additional REMPI. This points to a number of exciting opportunities for both basic and applied science. On the applied side, REMPI has great potential as an ultrasensitive, highly selective detector for trace, reactive, or transient species. On the basic side, REMPI affords an unprecedented means of exploring excited state physics and chemistry at the quantum-state-specific level. An overview of current studies of excited molecular states is given to illustrate the principles and prospects of REMPI

Perceptions of Well-Being Among Rural Nebraskans

Nebraska’s economy has been relatively stable during the past year. However, some rural areas continue to be economically challenged. How do rural Nebraskans perceive their quality of life? Do their perceptions differ by community size, the region in which they live, or their occupation? This report details 2,482 responses to the 2006 Nebraska Rural Poll, the eleventh annual effort to understand rural Nebraskans’ perceptions. Respondents were asked a series of questions regarding their individual well-being. Trends for these questions are examined by comparing data from the ten previous polls to this year’s results. In addition, comparisons are made among different respondent subgroups, that is, comparisons by age, occupation, region, etc. Based on these analyses, some key findings emerged: • More rural Nebraskans report being satisfied with their job opportunities this year as compared to previous years. After reaching a low of 34 percent in 2004, the proportion satisfied with their job opportunities increased to 42 percent this year (the highest proportion in all 11 years). (page 5) • Persons with the highest household incomes are more likely than persons with lower incomes to feel they are better off compared to five years ago, are better off compared to their parents when they were their age, and will be better off ten years from now. For example, 52 percent of respondents with household incomes of $60,000 or more think they will be better off ten years from now. However, only 22 percent of respondents with household incomes under$20,000 believe they will be better off ten years from now. (page 6) • More rural Nebraskans believe people are powerless to control their own lives this year as compared to past years. The proportion that either strongly agree or agree with the statement that people are powerless to control their own lives each year has averaged about 34 percent. The proportion agreeing with the statement increased slightly, to 38 percent this year, which matches the highest proportion in the 11 years of the Poll (1997 and 1999 were the other two years). (page 4) • Persons with lower education levels are more likely than persons with more education to believe that people are powerless to control their own lives. Forty-six percent of persons with a high school diploma or less education agree that people are powerless to control their own lives. However, only 25 percent of persons with a four-year college degree share this opinion. (page 9) • Rural Nebraskans continue to be generally positive about their current situation. Except in 2003, each year the proportion of rural Nebraskans that say they are better off than they were five years ago has been greater than the proportion saying they are worse off than they were five years ago. Approximately 36 percent each year have reported that they were better off than they were five years ago. This year, 35 percent believe they are better off then they were five years ago and 21 percent think they are worse off. (page 2) • Similarly, rural Nebraskans continue to be generally positive about their future. The proportion that say they will be better off ten years from now has always been greater than the proportion saying they will be worse off ten years from now (although the two were virtually identical in 1996). The proportion stating they will be better off ten years from now has generally remained about 36 percent. This year, the proportion was 34 percent. Twenty-one percent believe they will be worse off ten years from now. (page 3) • Following trends in previous years, rural Nebraskans are most satisfied with their marriage, family, friends, religion/spirituality and the outdoors. They continue to be less satisfied with job opportunities, current income level and financial security during retirement. (page 5

Rhizobium radiobacter Endophthalmitis following Intravitreal Ranibizumab Injection.

We present the first reported case of acute endophthalmitis due to Rhizobium radiobacter after an intravitreal injection of ranibizumab for neovascular age-related macular degeneration

Joy without demands: Hospital clowns in the world of ailing children

The aim of the present study was to achieve, using an affect theory approach (Tomkins, 1962; 1963; 1991), a deeper theoretical understanding of the psychological significance of hospital clowns' work in caring for ailing children viewed from a care-giver perspective. The methodological approach was qualitative and based on 20 interviews with healthcare staff: 3 men and 17 women. The result showed how the staff emphasized a psychological quality of care alongside the physical quality of care. The hospital clowns' “unexpected possibility” provided a safe area for recovery, for both the children and the staff. The theoretical interpretation showed the presence of the affects surprise/startle, interest/excitement, and enjoyment/joy as well as specifically how “joy without demands” often had a lingering effect in the form of vitality. Joy without demands is discussed in relation to psychological theory with emphasis on: a confirmation of the body's possibilities, a magical attachment, a chance to transcend boundaries, and a non-demanding situation

Perceptions of Latin American Immigration Among Rural Nebraskans

In an earlier Nebraska Rural Poll report (August 2006), rural Nebraskans were asked their opinions of newcomers in general to their community. Some parts of rural Nebraska have seen significant growth of a specific group of newcomers, Latin American immigrants. How do rural Nebraskans view recent immigrants from Latin America? How do they view various immigration policies? Do their views differ by community size, the region in which they live, or their education level? This report details 2,482 responses to the 2006 Nebraska Rural Poll, the eleventh annual effort to understand rural Nebraskans’ perceptions of current issues and conditions. Respondents were asked a series of questions regarding immigrants from Latin America and immigration policies. Comparisons are made among different respondent subgroups, that is, comparisons by age, occupation, region, etc

Construction and characterization of a BAC-library for a key pollinator, the bumblebee Bombus terrestris L

Abstract.: The primitively social bumblebee Bombus terrestris is an ecological model species as well as an important agricultural pollinator. As part of the ongoing development of genomic resources for this model organism, we have constructed a publicly available bacterial artificial chromosome (BAC) library from males of a field-derived colony. We have shown that this library has a high coverage, which allows any particular sequence to be retrieved from at least one clone with a probability of 99.7%. We have further demonstrated the library's usefulness by successfully screening it with probes derived both from previously described B. terrestris genes and candidate genes from another bumblebee species and the honeybee. This library will facilitate genomic studies in B. terrestris and will allow for novel comparative studies in the social Hymenopter

'Redlands for Regions': Producer demonstration sites of psyllid-resistant leucaena across north Queensland

Leucaena, a tree legume with potential to greatly improve cattle performance, has not been readily adopted in northern Queensland primarily due to prevalence of the psyllid (Heteropsylla cubana) insect in higher rainfall zones. Psyllids reduce edible biomass in leaves by 40–52%, combined with a 46–83% reduction of stem yield (Bray and Woodroffe 1991). Losses to the Central Queensland beef industry due to psyllid impact on animal performance are estimated at $2 M per year (Mullen et al. 1998). Cultivar Redlands is a psyllid-resistant leucaena variety recently developed by Meat and Livestock Australia (MLA) and the University of Queensland

Prompt Burst Energetics (PBE) experiment analyses using the SIMMER-II computer code. [LMFBR]

Two of the Prompt Burst Energetics (PBE) in-pile experiments conducted at Sandia Laboratories PBE-5S and PBE-SG2, have been investigated with SIMMER-II. These two tests utilize fresh uranium oxide and fresh uranium carbide pins, respectively, in stagnant sodium. The purpose of the analysis is to investigate the applicability of SIMMER-II to this type of experiment. Qualitative agreement with measured data is seen for PBE-5S. PBE-SG2 results agree somewhat less well but demonstrate SIMMER-II's potential for describing fuel-coolant-interactions with further model development

Intravitreal bevacizumab injections for diabetic macular edema - predictors of response: a retrospective study

BACKGROUND: Outcomes of intravitreal antivascular endothelial growth factor injections are variable among patients with diabetic macular edema (DME). The aim of this study was to determine the ocular and systemic predictors of DME response to intravitreal bevacizumab (IVB). METHODS: Retrospective review over 2 years of 78 eyes from 54 patients. An anatomical response to IVB was defined as a 20% reduction in central macula thickness after the first course (three injections) of IVB. RESULTS: Twenty-eight percent of patients had an anatomical response after the first course of IVB. Systemic hypertension (odds ratio, 95% confidence interval: 12.1, 0.7-21) was a statistically significant predictor (P=0.025) of a good response to IVB, whereas previous macular laser was a statistically significant (P=0.0005) predictor of a poor response (0.07, 0.01-0.32). Sixty-eight percent of eyes underwent subsequent treatment for DME after the first course of IVB. The visual acuity gain at 24 months in hypertensive (0.7±3.6 letters) and nonhypertensive (5.2±3.7 letters) patients was not significantly different (P=0.41). CONCLUSION: Hypertension and previous macular laser were positive and negative predictors of response to IVB, respectively. However, long-term visual acuity changes were not significantly different between eyes with and without systemic hypertension
