Living in Rural Nebraska: Quality of Life and Financial Well-Being

Nebraska’s economy growth has slowed this past year, and recent reports show that some of Nebraska’s counties are the poorest in the nation. How have these changes affected rural Nebraskans? 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? How have they responded to the higher cost of living? Are they able to meet their financial goals? This report details 3,199 responses to the 2001 Nebraska Rural Poll, the sixth annual effort to understand rural Nebraskans’ perceptions. Respondents were asked a series of questions regarding their general well-being, their satisfaction with specific aspects of well-being, and how they are responding to the higher cost of living. Trends for the well-being questions are examined by comparing data from the five previous polls to this year’s results. For all questions, comparisons are made among different respondent subgroups, i.e., comparisons by age, occupation, region, etc. Based on these analyses, some key findings emerged: • Rural Nebraskans are more negative about their current situation than they were last year. This year, 32 percent state they are better off than they were five years ago; however, this compares to 40 percent in 2000. This is the lowest percentage reported during a six-year period. Nineteen percent of the respondents say they are worse off than five years ago, while 16 percent felt this way last year. The percent responding that their situation remained about the same increased from 44 percent last year to 49 percent in 2001. • When asked about the future, fewer respondents assert they will be better off ten years from now, as compared to last year’s results. This year, 34 percent state they will be better off ten years from now, compared to 38 percent last year. The proportion responding they will be worse off increased from 18 percent to 21 percent. The proportion saying they will be about the same in ten years remained steady at 45 percent. • Farmers and ranchers are less optimistic than persons with other occupations about their current situation. Only 24 percent of the farmers and ranchers state they are better off compared to five years ago. In comparison, 50 percent of those with professional occupations say they are better off. • Manual laborers are more likely to believe that people are powerless to control their own lives. Just over one-half (51%) of the manual laborers either strongly agree or agree with the statement that “...people are powerless to control their own lives.” In contrast, only 21 percent of persons with professional occupations agree with the statement. • Respondents report being most satisfied with their family, their marriage, and their religion/spirituality. The items receiving the highest proportion of “very dissatisfied” responses include financial security during retirement, current income level and job opportunities. • Manual laborers are more likely than those with other occupations to express dissatisfaction with their job opportunities. Sixty percent of the manual laborers are dissatisfied with their job opportunities, compared to only 32 percent of the farmers and ranchers. • At least one-third of rural Nebraskans have experienced the following economic hardships during the past year: using savings to meet household expenses, delaying a family vacation because of a lack of money, and being unable to contribute any money toward retirement because the money was needed for everyday household expenses. Twenty percent of rural Nebraskans have taken another job to help meet household expenses during the past year. Seventeen percent couldn’t pay the full amount of their utility bills, 15 percent were unable to afford needed medical care, and seven percent were unable to purchase needed food. • The groups most likely to have experienced many of the hardships listed include: younger respondents, persons living in the North Central region of the state, respondents with lower income levels, females, persons with lower educational levels, the divorced or separated respondents, and the laborers. • Sixty-two percent of rural Nebraskans believe their household income has not kept up with the increased cost of living. Eighteen percent believe it has increased at the same rate as the cost of living, eight percent feel their income has increased faster than the cost of living, and 12 percent are not sure. • Just over one-half of rural Nebraskans say they have just enough to make ends meet at the end of each month. Fifty-two percent say they have just enough to make ends meet, 35 percent end up with money left over at the end of the month, and 13 percent say there is not enough money to make ends meet. • The vast majority of rural Nebraskans say they always had enough food to eat during the past year. Ninety-two percent said they always had enough food, seven percent said there were a few times when they didn’t have enough to eat, and one percent said there were many times when they didn’t have enough to eat. • Younger respondents were more likely than older respondents to say there were a few times when they didn’t have enough to eat last year. Twenty percent of the persons between the ages of 19 and 29 said there were a few times when they didn’t have enough to eat, compared to only three percent of the persons age 65 and older

Working Together: Rural Nebraskans’ Views of Regional Collaboration

Some people support regional collaboration because they believe it better enables communities to increase the region’s economic vitality and quality of life. However, others worry that such collaboration threatens individual communities’ identities and limits citizens’ access to services. How do rural Nebraskans view regional collaboration? Do they support combining certain services with neighboring communities or counties more than others? Are they already purchasing their goods and services outside their local community? This report details 3,087 responses to the 2003 Nebraska Rural Poll, the eighth annual effort to understand rural Nebraskans’ perceptions. Respondents were asked a series of questions about regional collaboration. Comparisons were made among different respondent subgroups, i.e., comparisons by age, occupation, region, etc. Based on these analyses, some key findings emerged: • Most rural Nebraskans have a positive view of regional collaboration. At least three-quarters either strongly agreed or agreed that “communities in a region working together to generate new businesses are better able to create quality jobs for their residents” (82%) and “retail businesses in a region can provide a better variety of goods and services by working together collaboratively” (75%). Sixty percent agreed that combining community or county services will improve access to services. Fifty-nine percent disagreed that combining services would lead to lower quality services and 47 percent disagreed that combining services would lead to increased prices for the consumer. • Persons with higher education levels, younger respondents, persons with higher incomes and females are the groups most likely to have a positive view of regional collaboration. • At least one-half of rural Nebraskans are willing to raise revenue to keep fire protection and emergency medical services at their current level. When asked how they would cover the costs of various services if faced with a shortage of money, 53 percent were willing to raise revenue to support fire protection services and 50 percent would raise revenue to maintain emergency medical services. Forty-eight percent were willing to raise revenue for their schools (K - 12). • Over one-half of rural Nebraskans would combine or share the following services with other nearby communities or counties if faced with a shortage of money: county road maintenance, veterans services, health clinic, telecommunications services, economic development activities, licenses and permits, street maintenance, property assessment and county weed control. • Younger persons are more likely than older persons to support raising revenue to keep their school services at their current level. Seventy-six percent of the persons age 19 to 29 supported raising revenue to keep their school services at their current level. Only 35 percent of the persons age 65 and older supported raising revenue. The older respondents were more likely than the younger respondents to support combining the school with other nearby communities or reducing its level of service. Forty-five percent of the persons age 65 and older supported combining their school with others and 14 percent said they would reduce its level of service. In comparison, only 21 percent of the persons age 19 to 29 supported combining their school with other communities and only two percent supported reducing its level of service. • Persons living in or near the largest communities are more likely than the persons living in or near the smallest communities to support raising revenue to keep their school services the same. Fifty-two percent of the persons living in or near the communities with populations of 10,000 or more supported raising revenue to keep their school’s services at their current level. Only 39 percent of the persons living in or near communities with less than 500 people supported this option. The persons living in or near the smallest communities were slightly more likely to support combining their school with other communities and were also more likely to not currently have a school in their community. • Differences in the level of support for various alternatives to cover the costs of law enforcement are detected by community size. Persons living in or near the smallest communities were more likely than the persons living in or near the larger communities to say they don’t have law enforcement. Persons living in or near communities with populations ranging from 500 to 999 were the group most likely to support combining law enforcement services with another community or county. Persons living in or near the largest communities were more likely than the persons living in or near the smaller communities to advocate raising revenue to keep their law enforcement services at their current level. • Farmers and ranchers are more likely than persons with different occupations to say they would raise revenue to maintain their county roads. Thirty-two percent of the farmers and ranchers would raise revenue to keep their county road maintenance services at their current level. Only 15 percent of the persons with sales and administrative support occupations agreed. • On average, at least one-half of the following items are purchased by rural Nebraskans in their local community: banking/financial services (75.7%), groceries (73%), automobile/machinery repairs (72%), insurance (67%), farm and ranch inputs (66.9%), doctor/clinic services (63.6%) and hospital services (57.3%). • For each item, rural Nebraskans living in or near the larger communities purchased more locally than did those living in or near the smaller communities. As an example, persons living in or near the communities with populations of 10,000 or more purchased an average of 96.1% of their groceries in their local community. Persons living in or near communities with less than 500 people purchased an average of 38.2% of their groceries in their local community. For most items, respondents living in the smallest communities purchased at least one-half in another community within 50 miles. • For most items, Panhandle residents purchased more in their local community than did residents living in other parts of the state. As an example, Panhandle residents purchased an average of 53.5% of their recreation/entertainment in their local community, compared to an average of 38.7% for Southeast residents. But, South Central residents were more likely than other regional groups to have purchased hospital services, banking/financial services and insurance locally

What should an index of school segregation measure?

The article aims to make a methodological contribution to the education segregation literature, providing a critique of previous measures of segregation used in the literature, as well as suggesting an alternative approach to measuring segregation. Specifically, the paper examines Gorard, Fitz and Taylor's finding that social segregation between schools, as measured by free school meals (FSM) entitlement, fell significantly in the years following the 1988 Education Reform Act. Using Annual Schools Census data from 1989 to 2004, the paper challenges the magnitude of their findings, suggesting that the method used by Gorard et al. seriously overstates the size of the fall in segregation. We make the case for a segregation curve approach to measuring segregation, where comparisons of the level of segregation are possible regardless of the percentage FSM eligibility. Using this approach, we develop a new method for describing both the level and the location of school segregation

Evolved galaxies in high-density environments across 2.0≤z<4.22.0\leq z<4.2 using the ZFOURGE survey

To explore the role environment plays in influencing galaxy evolution at high redshifts, we study $2.0\leq z<4.2$ environments using the FourStar Galaxy Evolution (ZFOURGE) survey. Using galaxies from the COSMOS legacy field with ${\rm log(M_{*}/M_{\odot})}\geq9.5$, we use a seventh nearest neighbour density estimator to quantify galaxy environment, dividing this into bins of low, intermediate and high density. We discover new high density environment candidates across $2.0\leq z<2.4$ and $3.1\leq z<4.2$. We analyse the quiescent fraction, stellar mass and specific star formation rate (sSFR) of our galaxies to understand how these vary with redshift and environment. Our results reveal that, across $2.0\leq z<2.4$, the high density environments are the most significant regions, which consist of elevated quiescent fractions, ${\rm log(M_{*}/M_{\odot})}\geq10.2$ massive galaxies and suppressed star formation activity. At $3.1\leq z<4.2$, we find that high density regions consist of elevated stellar masses but require more complete samples of quiescent and sSFR data to study the effects of environment in more detail at these higher redshifts. Overall, our results suggest that well-evolved, passive galaxies are already in place in high density environments at $z\sim2.4$, and that the Butcher-Oemler effect and SFR-density relation may not reverse towards higher redshifts as previously thought.Comment: 11 pages, 5 figures, final version published in PAS

Cross-modal interference-control is reduced in childhood but maintained in aging: a cohort study of stimulus-and response-interference in cross-modal and unimodal Stroop tasks

Interference-control is the ability to exclude distractions and focus on a specific task or stimulus. However, it is currently unclear whether the same interference-control mechanisms underlie the ability to ignore unimodal and cross-modal distractions. In two experiments we assessed whether unimodal and cross-modal interference follow similar trajectories in development and aging and occur at similar processing levels. In Experiment 1, 42 children(6-11 years), 31 younger adults (18-25 years) and 32 older adults (60-84 years) identified colour rectangles with either written (unimodal) or spoken (cross-modal) distractor-words. Stimuli could be congruent, incongruent but mapped to the same response (stimulus-incongruent), or incongruent and mapped to different responses (response-incongruent), thus separating interference occurring at early (sensory) and late (response) processing levels. Unimodal interference was worst in childhood and old age; however, older adults maintained the ability to ignore cross-modal distraction. Unimodal but not cross-modal response interference also reduced accuracy. In Experiment 2 we compared the effect of audition on vision and vice versa in 52 children (6-11 years), 30 young adults (22-33 years) and 30 older adults (60-84 years). As in Experiment 1, older adults maintained the ability to ignore cross-modal distraction arising from either modality and neither type of cross-modal distraction limited accuracy in adults. However cross-modal distraction still reduced accuracy in children and children were more slowed by stimulus-interference compared with adults. We conclude that; unimodal and cross-modal interference follow different lifespan trajectories and differences in stimulus- and response-interference may increase cross-modal distractibility in childhood

Network analysis reveals underlying syntactic features in a vocally learnt mammalian display, humpback whale song

J.A.A. was funded by an Australian Government Research Training Program Scholarship and the Australian American Association University of Queensland Fellowship. E.C.G. was funded by a Royal Society Newton International Fellowship and a Royal Society University Research Fellowship. HARC was funded by the US Office of Naval Research, the Australian Defence Science and Technology Organisation, and the Australian Marine Mammal Centre. BRAHSS was funded by the E&P Sound and Marine Life Joint Industry Programme and the US Bureau of Ocean Energy Management.Vocal communication systems have a set of rules that govern the arrangement of acoustic signals, broadly defined as ‘syntax’. However, there is a limited understanding of potentially shared or analogous rules across vocal displays in different taxa. Recent work on songbirds has investigated syntax using network-based modelling. This technique quantifies features such as connectivity (adjacent signals in a sequence) and recurring patterns. Here, we apply network-based modelling to the complex, hierarchically structured songs of humpback whales (Megaptera novaeangliae) from east Australia. Given the song's annual evolving pattern and the cultural conformity of males within a population, network modelling captured the patterns of multiple song types over 13 consecutive years. Song arrangements in each year displayed clear ‘small-world’ network structure, characterized by clusters of highly connected sounds. Transitions between these connected sounds further suggested a combination of both structural stability and variability. Small-world network structure within humpback songs may facilitate the characteristic and persistent vocal learning observed. Similar small-world structures and transition patterns are found in several birdsong displays, indicating common syntactic patterns among vocal learning in multiple taxa. Understanding the syntactic rules governing vocal displays in multiple, independently evolving lineages may indicate what rules or structural features are important to the evolution of complex communication, including human language.PostprintPostprintPeer reviewe

Electrogenerated Chemiluminescence. 70. The Application of ECL to Determine Electrode Potentials of Tri-n-propylamine, Its Radical Cation, and Intermediate Free Radical in MeCN/Benzene Solutions †

We report here electrogenerated chemiluminescence (ECL) observed upon oxidation of aromatic hydrocarbons with different potentials for oxidation to the radical cations (D +• ) and tri-n-propylamine (TPrA) in MeCN/ benzene solutions. In this system, with TPrA as a coreactant, ECL is generated by reaction of D +• with the free radical intermediate produced upon oxidation of TPrA. ECL was observed from three out of the eight compounds studied. On the basis of the energetic criterion for ECL, the potential for oxidation of the intermediate free radical, Pr 2 N(CH • )Et, was found to be about -1.7 V vs SCE. By studying the fluorescence quenching of several polycyclic aromatic hydrocarbons (PAHs) by TPrA, the standard potential for oxidation of TPrA to TPrA +• was estimated as 0.9 V vs SCE

Stability of β-lactam antibiotics in bacterial growth media

Laboratory assays such as MIC tests assume that antibiotic molecules are stable in the chosen growth medium-but rapid degradation has been observed for antibiotics including β-lactams under some conditions in aqueous solution. Degradation rates in bacterial growth medium are less well known. Here, we develop a 'delay time bioassay' that provides a simple way to estimate antibiotic stability in bacterial growth media, using only a plate reader and without the need to measure the antibiotic concentration directly. We use the bioassay to measure degradation half-lives of the β-lactam antibiotics mecillinam, aztreonam and cefotaxime in widely-used bacterial growth media based on MOPS and Luria-Bertani (LB) broth. We find that mecillinam degradation can occur rapidly, with a half-life as short as 2 hours in MOPS medium at 37°C and pH 7.4, and 4-5 hours in LB, but that adjusting the pH and temperature can increase its stability to a half-life around 6 hours without excessively perturbing growth. Aztreonam and cefotaxime were found to have half-lives longer than 6 hours in MOPS medium at 37°C and pH 7.4, but still shorter than the timescale of a typical minimum inhibitory concentration (MIC) assay. Taken together, our results suggest that care is needed in interpreting MIC tests and other laboratory growth assays for β-lactam antibiotics, since there may be significant degradation of the antibiotic during the assay

The ral exchange factor rgl2 promotes cardiomyocyte survival and inhibits cardiac fibrosis

Cardiomyocytes compensate to acute cardiac stress by increasing in size and contractile function. However, prolonged stress leads to a decompensated response characterized by cardiomyocyte death, tissue fibrosis and loss of cardiac function. Identifying approaches to inhibit this transition to a decompensated response may reveal important targets for treating heart failure. The Ral guanine nucleotide disassociation (RalGDS) proteins are Ras-interacting proteins that are upregulated by hypertrophic stimuli. The Ral guanine nucleotide dissociation stimulator-like 2 (Rgl2) is a member of the RalGDS family that modulates expression of hypertrophic genes in cardiomyocytes. However, the pathophysiologic consequence of increased Rgl2 expression in cardiomyoctyes remains unclear. To evaluate the effect of increasing Rgl2 activity in the heart, transgenic mice with cardiac-targeted over-expression of Rgl2 were generated. Although Ral activation was increased, there were no apparent morphologic or histological differences between the hearts of Rgl2 transgenic and nontransgenic mice indicating that increased Rgl2 expression had no effect on basal cardiac phenotype. To determine if Rgl2 modulates the cardiac response to stress, mice were infused with the ß-adrenergic receptor agonist, isoproterenol. Isoproterenol infusion increased heart mass in both Rgl2 transgenic and nontransgenic mice. However, unlike nontransgenic mice, Rgl2 transgenic mice showed no morphologic evidence of cardiomyocyte damage or increased cardiac fibrosis following isoproterenol infusion. Increased Rgl2 expression in cultured cardiomyocytes stimulated Ral activation and inhibited staurosporine-induced apoptosis via increased activation of PI3-kinase. Activation of the PI3-kinase signaling pathway was confirmed in hearts isolated from Rgl2 transgenic mice. Increased expression and function of Rgl2 in cardiomyocytes promotes activation of the PI3-kinase signaling cascade and protects from carciomyocyte death and pathologic cardiac fibrosis. Taken further, these results suggest that Rgl2 upregulation in hypertrophic hearts may be a protetive mechanism, and that Rgl2 may be a novel therapeutic target in treating heart disease

Potassium, Calcium, and Magnesium Bridging of AOT to Mica at Constant Ionic Strength.

The bridging effect of a series of common cations between the anionic mica surface and the AOT anion has been studied in a condition of constant ionic strength and surfactant concentration. It was found that sodium ions did not show any bridging effect in this system; however, calcium, magnesium, and potassium all caused adsorption of the organic to the mica surface. The concentrations at which bridging occurred was probed, revealing that only a very low bridging cation concentration was required for binding. The bridged layer stability was also investigated, and the interaction was shown to be a weak one, with the bound layer in equilibrium with the species in the bulk and easily removed. Even maintaining ionic strength and bridging ion concentration was not sufficient to retain the layer when the free organic in solution was removed.We thank EPSRC and BP plc for the funding (RG8620) that made this work possible
