Attitudes Toward Immediate Annuities

Retirement security for Americans is one of the most critical public policy and personal financial issues and will be for decades in the future. Individuals that retire today can live an additional 30 or even 40 years with less secure income as corporations shift to defined contribution plans to fund retirement. Based on the life cycle savings hypothesis, immediate annuities should be appealing to retirees because they insure against the risks of outliving retirement assets by converting funds into a lifelong stream of income. However, research has found that retirees are reluctant to annuitize their wealth. This study examined the attitudes of Utah State University employees toward annuitization of retirement assets and explored the relationship between employee characteristics and their attitudes toward immediate annuities. Data for this study were collected through an online questionnaire emailed to Utah State University employees who participate in a defined contribution plan. The survey gathered information on retirement portfolio losses, expected longevity, financial confidence, familiarity with annuities, and attitudes toward immediate annuities. A total of 744 individuals answered the survey for a response rate of 43.2%. Based on the results of independent t tests, there were statistically significant differences between the attitudes of women and men toward immediate annuities. Women held more positive attitudes toward immediate annuities than men, and women who had taken a retirement planning class had more positive attitudes than women who had not attended a retirement class. In contrast, men who had attended a retirement class expressed less positive attitudes toward immediate annuities than men who had not. Male overconfidence in their investment knowledge and skills may explain this finding. A Pearson correlation coefficient revealed a negative correlation between risk aversion and attitudes toward annuities. As investment risk tolerance decreases, attitudes toward immediate annuities become more positive. An analysis of variance found that individuals with longer than average life expectancies had more positive attitudes toward immediate annuities than subjects with shorter than average life expectancies. Surprisingly, individuals who claimed to be most familiar with immediate annuities showed the least positive attitudes toward annuities. Income and assets, marital status, and financial confidence were not statistically significantly related to attitudes toward annuities. Implications for consumers, financial professionals, educators, and policymakers were drawn from the results of the study

Spying on Friends: British Assessments of French Security, 1945–50

The emergence of intelligence studies as a distinctive branch of international history has provided many new insights into the nature of international affairs during the past thirty years. Certain aspects of intelligence, however, remain largely overlooked. One such area, which is the focus of this article, is that of bureaucratic security: how a state ensures the security of the information that it holds and how it disseminates this information throughout its bureaucracies and with its allies. Whilst this may appear as a mundane avenue for investigation, this piece demonstrates that bureaucratic security issues had an impact on ‘high-level’ political decisions during the creation of the North Atlantic Treaty Organization (NATO), adversely affected relations between the United Kingdom and France, and created additional problems surrounding the emergence of an integrated military framework within the NATO alliance

The role of quantum fluctuations in the optomechanical properties of a Bose-Einstein condensate in a ring cavity

We analyze a detailed model of a Bose-Einstein condensate trapped in a ring optical resonator and contrast its classical and quantum properties to those of a Fabry-P{\'e}rot geometry. The inclusion of two counter-propagating light fields and three matter field modes leads to important differences between the two situations. Specifically, we identify an experimentally realizable region where the system's behavior differs strongly from that of a BEC in a Fabry-P\'{e}rot cavity, and also where quantum corrections become significant. The classical dynamics are rich, and near bifurcation points in the mean-field classical system, the quantum fluctuations have a major impact on the system's dynamics.Comment: 11 pages, 11 figures, submitted to PR

Investigating magnetic activity in very stable stellar magnetic fields: long-term photometric and spectroscopic study of the fully convective M4 dwarf V374 Peg

The ultrafast-rotating ($P_\mathrm{rot}\approx0.44 d$) fully convective single M4 dwarf V374 Peg is a well-known laboratory for studying intense stellar activity in a stable magnetic topology. As an observable proxy for the stellar magnetic field, we study the stability of the light curve, and thus the spot configuration. We also measure the occurrence rate of flares and coronal mass ejections (CMEs). We analyse spectroscopic observations, $BV(RI)_C$ photometry covering 5 years, and additional $R_C$ photometry that expands the temporal base over 16 years. The light curve suggests an almost rigid-body rotation, and a spot configuration that is stable over about 16 years, confirming the previous indications of a very stable magnetic field. We observed small changes on a nightly timescale, and frequent flaring, including a possible sympathetic flare. The strongest flares seem to be more concentrated around the phase where the light curve indicates a smaller active region. Spectral data suggest a complex CME with falling-back and re-ejected material, with a maximal projected velocity of $\approx$675km/s. We observed a CME rate much lower than expected from extrapolations of the solar flare-CME relation to active stars.Comment: 15 figures, 4 tables, accepted for publication in A&

Socioeconomic inequalities in attitudes towards cancer: an international cancer benchmarking partnership study.

Socioeconomic status (SES) differences in attitudes towards cancer have been implicated in the differential screening uptake and the timeliness of symptomatic presentation. However, the predominant emphasis of this work has been on cancer fatalism, and many studies focus on specific community subgroups. This study aimed to assess SES differences in positive and negative attitudes towards cancer in UK adults. A population-based sample of UK adults (n=6965, age≥50 years) completed the Awareness and Beliefs about Cancer scale, including six belief items: three positively framed (e.g. 'Cancer can often be cured') and three negatively framed (e.g. 'A cancer diagnosis is a death sentence'). SES was indexed by education. Analyses controlled for sex, ethnicity, marital status, age, self-rated health, and cancer experience. There were few education-level differences for the positive statements, and overall agreement was high (all>90%). In contrast, there were strong differences for negative statements (all Ps<0.001). Among respondents with lower education levels, 57% agreed that 'treatment is worse than cancer', 27% that cancer is 'a death sentence' and 16% 'would not want to know if I have cancer'. Among those with university education, the respective proportions were 34, 17 and 6%. Differences were not explained by cancer experience or health status. In conclusion, positive statements about cancer outcomes attract near-universal agreement. However, this optimistic perspective coexists alongside widespread fears about survival and treatment, especially among less-educated groups. Health education campaigns targeting socioeconomically disadvantaged groups might benefit from a focus on reducing negative attitudes, which is not necessarily achieved by promoting positive attitudes

See No, Smell No, Taste No Evil: How Sage-Grouse Detect Toxic Sagebrush

There is increasing evidence that sage-grouse selectively consume individual and species of sagebrush that have the lowest concentrations of chemical defenses, or toxins. We propose that this selection requires the ability to see, smell or taste specific chemicals or groups of chemicals that vary quantitatively and qualitatively in sagebrush available throughout the winter range of sage-grouse. We are developing methods to determine if and how selected and avoided sagebrush may differ in color, smell and taste. We used ultraviolet and near infrared detectors to determine the variation in the color of phenolics in sagebrush. We used gas chromatography to determine the variation in the smell of monoterpenes in sagebrush. We are developing microscopy techniques to determine if sage-grouse possess receptors in the beak and tongue that could taste chemicals in sagebrush. Our goal is to develop detectors that can act as sage-grouse eyes, nose and mouth and allow managers to identify and conserve the least toxic sagebrush for foraging sage-grouse

Autosomal dominant cerebellar ataxia type I: A review of the phenotypic and genotypic characteristics

Type I autosomal dominant cerebellar ataxia (ADCA) is a type of spinocerebellar ataxia (SCA) characterized by ataxia with other neurological signs, including oculomotor disturbances, cognitive deficits, pyramidal and extrapyramidal dysfunction, bulbar, spinal and peripheral nervous system involvement. The global prevalence of this disease is not known. The most common type I ADCA is SCA3 followed by SCA2, SCA1, and SCA8, in descending order. Founder effects no doubt contribute to the variable prevalence between populations. Onset is usually in adulthood but cases of presentation in childhood have been reported. Clinical features vary depending on the SCA subtype but by definition include ataxia associated with other neurological manifestations. The clinical spectrum ranges from pure cerebellar signs to constellations including spinal cord and peripheral nerve disease, cognitive impairment, cerebellar or supranuclear ophthalmologic signs, psychiatric problems, and seizures. Cerebellar ataxia can affect virtually any body part causing movement abnormalities. Gait, truncal, and limb ataxia are often the most obvious cerebellar findings though nystagmus, saccadic abnormalities, and dysarthria are usually associated. To date, 21 subtypes have been identified: SCA1-SCA4, SCA8, SCA10, SCA12-SCA14, SCA15/16, SCA17-SCA23, SCA25, SCA27, SCA28 and dentatorubral pallidoluysian atrophy (DRPLA). Type I ADCA can be further divided based on the proposed pathogenetic mechanism into 3 subclasses: subclass 1 includes type I ADCA caused by CAG repeat expansions such as SCA1-SCA3, SCA17, and DRPLA, subclass 2 includes trinucleotide repeat expansions that fall outside of the protein-coding regions of the disease gene including SCA8, SCA10 and SCA12. Subclass 3 contains disorders caused by specific gene deletions, missense mutation, and nonsense mutation and includes SCA13, SCA14, SCA15/16, SCA27 and SCA28. Diagnosis is based on clinical history, physical examination, genetic molecular testing, and exclusion of other diseases. Differential diagnosis is broad and includes secondary ataxias caused by drug or toxic effects, nutritional deficiencies, endocrinopathies, infections and post-infection states, structural abnormalities, paraneoplastic conditions and certain neurodegenerative disorders. Given the autosomal dominant pattern of inheritance, genetic counseling is essential and best performed in specialized genetic clinics. There are currently no known effective treatments to modify disease progression. Care is therefore supportive. Occupational and physical therapy for gait dysfunction and speech therapy for dysarthria is essential. Prognosis is variable depending on the type of ADCA and even among kindreds

The Dynamics of Asymmetric Stratified Shear Instabilities

Most idealized studies of stratified shear instabilities assume that the shear interface and the buoyancy interface are coincident. We discuss the role of asymmetry on the evolution of shear instabilities. Using linear stability theory and direct numerical simulations, we show that asymmetric shear instabilities exhibit features of both Holmboe and Kelvin-Helmholtz (KH) instabilities, and develop a framework to quantify if the instabilities are more Holmboe-like or more KH-like. Further, the asymmetric instabilities produce asymmetric mixing that exhibits features of both overturning and scouring flows and that tends to realign the shear and buoyancy interfaces. In all but the symmetric KH simulations, we observe a collapse in the distribution of gradient Richardson number ($Ri_g$), suggesting that asymmetry reduces the parameter dependence of KH-driven mixing events. The observed dependence of the turbulent dynamics on small-scale details of the shear and stratification has important implications for the interpretation of oceanographic data.Comment: 9 Figures, 21 page

Photometric Monitoring of the Gravitationally Lensed Ultraluminous BAL Quasar APM08279+5255

We report on one year of photometric monitoring of the ultraluminous BAL quasar APM 08279+5255. The temporal sampling reveals that this gravitationally lensed system has brightened by ~0.2 mag in 100 days. Two potential causes present themselves; either the variability is intrinsic to the quasar, or it is the result of microlensing by stars in a foreground system. The data is consistent with both hypotheses and further monitoring is required before either case can be conclusively confirmed. We demonstrate, however, that gravitational microlensing can not play a dominant role in explaining the phenomenal properties exhibited by APM 08279+5255. The identification of intrinsic variability, coupled with the simple gravitational lensing configuration, would suggest that APM 08279+5255 is a potential golden lens from which the cosmological parameters can be derived and is worthy of a monitoring program at high spatial resolution.Comment: 17 pages, with 2 figures.

Estimating species trees using multiple-allele DNA sequence data

Several techniques, such as concatenation and consensus methods, are available for combining data from multiple loci to produce a single statement of phylogenetic relationships. However, when multiple alleles are sampled from individual species, it becomes more challenging to estimate relationships at the level of species, either because concatenation becomes inappropriate due to conflicts among individual gene trees, or because the species from which multiple alleles have been sampled may not form monophyletic groups in the estimated tree. We propose a Bayesian hierarchical model to reconstruct species trees from multiple-allele, multilocus sequence data, building on a recently proposed method for estimating species trees from single allele multilocus data. A two-step Markov Chain Monte Carlo (MCMC) algorithm is adopted to estimate the posterior distribution of the species tree. The model is applied to estimate the posterior distribution of species trees for two multiple-allele datasets - yeast (Saccharomyces) and birds (Manacus - manakins). The estimates of the species trees using our method are consistent with those inferred from other methods and genetic markers, but in contrast to other species tree methods, it provides credible regions for the species tree. The Bayesian approach described here provides a powerful framework for statistical testing and integration of population genetics and phylogenetics. © 2008 The Author(s)
