Health Care and the Unemployed

[Excerpt] On a chilly evening in March more than 50 residents of Calumet City Illinois, gathered to hear the findings and recommendations from a survey conducted last fall by the South Suburban Task Force on the Health Impact of Unemployment and Low Income. The Task Force had conducted interviews with unemployed workers in Calumet City and two other south Cook County communities. We wanted to find out the impact unemployment was having on people\u27s health and their ability to get health care. The Task Force\u27s 90-page report, The Health Impact of Unemployment and Low Income, was released in March 1984. It summarized key findings and recommendations based on interviews with unemployed workers and surveys of local physicians, dentists, and health and social service agencies. The Midwest Center for Labor Research (MCLR), along with four local health agencies, conducted the study

Molecular and functional basis of phenotypic convergence in white lizards at White Sands

There are many striking examples of phenotypic convergence in nature, in some cases associated with changes in the same genes. But even mutations in the same gene may have different biochemical properties and thus different evolutionary consequences. Here we dissect the molecular mechanism of convergent evolution in three lizard species with blanched coloration on the gypsum dunes of White Sands, New Mexico. These White Sands forms have rapidly evolved cryptic coloration in the last few thousand years, presumably to avoid predation. We use cell-based assays to demonstrate that independent mutations in the same gene underlie the convergent blanched phenotypes in two of the three species. Although the same gene contributes to light phenotypes in these White Sands populations, the specific molecular mechanisms leading to reduced melanin production are different. In one case, mutations affect receptor signaling and in the other, the ability of the receptor to integrate into the melanocyte membrane. These functional differences have important ramifications at the organismal level. Derived alleles in the two species show opposite dominance patterns, which in turn affect their visibility to selection and the spatial distribution of alleles across habitats. Our results demonstrate that even when the same gene is responsible for phenotypic convergence, differences in molecular mechanism can have dramatic consequences on trait expression and ultimately the adaptive trajectory.Organismic and Evolutionary Biolog

On Hirschman and log-Sobolev inequalities in mu-deformed Segal-Bargmann analysis

We consider a deformation of Segal-Bargmann space and its transform. We study L^p properties of this transform and obtain entropy-entropy inequalities (Hirschman) and entropy-energy inequalities (log-Sobolev) that generalize the corresponding known results in the undeformed theory.Comment: 42 pages, 3 figure

Deformation of quantum mechanics in fractional-dimensional space

A new kind of deformed calculus (the D-deformed calculus) that takes place in fractional-dimensional spaces is presented. The D-deformed calculus is shown to be an appropriate tool for treating fractional-dimensional systems in a simple way and quite analogous to their corresponding one-dimensional partners. Two simple systems, the free particle and the harmonic oscillator in fractional- dimensional spaces are reconsidered into the framework of the D-deformed quantum mechanics. Confined states in a D-deformed quantum well are studied. D-deformed coherent states are also found.Comment: 12 pages, some misprints have been corrected, two figures are adde

Strong, Safe, And Secure: Negotiating Early Fathering And Military Service Across The Deployment Cycle

Military fathers of young children often endure repeated separations from their children, and these may disrupt the early parent–child relationship. Postdeployment reunification also poses challenges; disruptions that have occurred must often be repaired in the context of heightened emotions on the part of each family member at a time when fathers are themselves readjusting to the routines and responsibilities of family life. The current study employed qualitative research with the central aim of informing a richer understanding of these experiences. Interviews were conducted with 14 military fathers of young children who had experienced separation from their families during deployment. Narratives were coded using principles of grounded theory, and common parenting themes were extracted. Fathers shared their hopes that their young children would develop qualities of strength, confidence, and self‐sufficiency. They also discussed difficulty in supporting the development of these qualities in their young children due to problems dealing with the negative emotions and difficult behaviors that their children exhibited. Reliance on their parenting partner was commonly cited as an effective strategy as fathers transitioned back to family life. Implications for intervention programs include the provision of parenting and self‐care skills and inclusion of the father's parenting partner in the intervention. RESUMEN Padres militares de niños pequeños a menudo enfrentan repetidas separaciones de sus hijos, las cuales pueden alterar las tempranas relaciones padre‐hijo. La reunificación posterior a la asignación militar también presenta retos; las interrupciones que han ocurrido muy a menudo se arreglan en el contexto de fuertes emociones por parte de cada miembro de la familia en un momento en que los papás están ellos mismos reajustándose a rutinas y responsabilidades de la vida familiar. La investigación cualitativa puede resultar en una mejor comprensión de estas experiencias. Para el presente estudio, se entrevistó a 14 militares, padres de niños pequeños, quienes habían experimentado la separación familiar durante sus asignaciones militares. Se codificaron las narrativas usando principios de teoría básica, y se extrajeron temas de crianza comunes. Los papás compartieron sus esperanzas de que sus pequeños niños desarrollaran su fortaleza, confianza y autosuficiencia. También discutieron la dificultad de apoyar el desarrollo de estas características en sus pequeños niños después de la separación por servicio militar debido a problemas relacionados con emociones negativas y conductas difíciles que sus hijos mostraban. Se citó reiteradamente el depender de la pareja en la crianza como estrategia efectiva en la transición de vuelta a la vida familiar. Las implicaciones para programas de intervención incluyen la incorporación de la pareja de quien dependen los papás para la crianza como parte de la intervención, así como la provisión de habilidades de crianza y autocuidado. RÉSUMÉ Les pères de jeunes enfants qui servent dans l’armée endurent souvent des séparations répétées d’avec leurs enfants, séparations qui peuvent perturber la relation précoce père‐enfant. La réunification après le déploiement peut également poser certains défis: les perturbations qui se sont passées doivent aussi être réparées dans le contexte d’émotions intensifiées de la part de chaque membre de la famille à un moment où les pères eux‐mêmes se réadaptent aux routines et aux responsabilités de la vie de famille. Des recherches qualitatives peuvent mener à une compréhension plus riche de ces expériences. Cette étude a interviewé 14 pères engagés dans l’armée, pères de jeunes enfants qui avaient tous fait l’expérience de la séparation de leurs familles durant le déploiement. Les récits ont été codés en utilisant les principes de la théorie ancrée et les thèmes de parentage commun ont été extraits. Les pères ont partagé leurs espoirs que leurs jeunes enfants feraient preuve de qualités de force, de confiance et d’auto‐suffisance en grandissant. Ils ont aussi discuté la difficulté qui existe à soutenir le développement de ces qualités chez leurs jeunes enfants après le déploiement à cause de problèmes liés aux émotions et aux comportements difficiles dont faisaient preuve leurs enfants. La dépendance envers le partenaire de parentage s’est trouvé fréquemment citée comme étant une stratégie efficace alors qu’ils transitionnaient dans le retour à la vie familiale. Les implications pour des programmes d’intervention comprennent l’inclusion du partenaire de parentage du père dans l’intervention et dans l’accumulation des précautions de parentage et des capacités à prendre soin de soi. ZUSAMMENFASSUNG Väter von Kleinkindern, die im Militär dienen, erfahren oft wiederholte Trennungen von ihren Kindern, welche die frühe Eltern‐Kind‐Beziehung stören können. Auch die Wiedervereinigung nach einem Einsatz beim Militär stellt eine Herausforderung dar: Brüche, die aufgetreten sind, müssen oft im Zusammenhang mit verstärkten Emotionen auf Seiten jedes Familienmitglieds wiedergutgemacht werden. Dies geschieht zu einer Zeit, in der sich die Väter wieder den Routinen und Aufgaben des Familienlebens anpassen. Qualitative Forschung kann zu einem umfangreicheren Verständnis dieser Erfahrungen beitragen. Die aktuelle Studie befragte 14 Väter von Kleinkindern, die beim Militär waren und Trennung von ihren Familien während eines Einsatzes erlebt hatten. Narrative wurden nach den Prinzipien der „Grounded Theory“ kodiert und allgemeine Themen zur Elternschaft wurden extrahiert. Die Väter teilten ihre Hoffnung mit, dass ihre Kinder Eigenschaften wie Stärke, Selbstvertrauen und Selbstständigkeit entwickeln. Sie diskutierten auch Schwierigkeiten bei der Unterstützung der Entwicklung dieser Eigenschaften bei ihren Kleinkindern nach einem Einsatz, aufgrund von Problemen im Umgang mit negativen Emotionen und schwierigen Verhaltensweisen, die ihre Kinder zeigten. Das Vertrauen in das andere Elternteil wurde allgemein als wirksame Strategie zitiert, wenn sie zurück ins Familienleben übergegangen sind. Implikationen für Interventionsprogramme umfassen die Einbeziehung des anderen Elternteils in die Intervention und die Bereitstellung von Erziehungs‐ und Selbstfürsorge‐Fähigkeiten. ABSTRACT 抄録：幼い子どものいる軍人の父親は、子どもとの別れを繰り返すことにしばしば耐えている。そして、これは、早期の親－子関係を中断するだろう。帰還後の家族の再統合もまた問題をはらんでいる。父親自身が家族生活のルーチンと責任に再適応している時に、家族メンバーそれぞれが高揚した感情というコンテクストの中で、生じていた中断がしばしば修復されなければならない。質的研究によりこれらの経験をより豊かに理解する情報をえることができる。この研究では、配備の間に家族との別れを体験した、14人の幼い子どものいる軍人の父親にインタビューした。談話はグランデット・セオリーの原則を用いてコード化され、共通の育児のテーマが抽出された。父親達は、幼い子どもが、強さ、自信、そして自給自足という素質を発達させるだろうという希望を共有していた。彼らはまた、子ども達が示す否定的な感情や難しい行動を扱う問題のために、帰還後に幼い子どものこれらの素質を発達させるように支援するのが難しいと議論した。養育パートナーへの信頼は、彼らが家族との生活に戻る移行における効果的な戦略として、共通して言及された。介入プログラムに対して持つ意味には、父親の養育パートナーを介入に含めること、そして養育スキルとセルフケアのスキルを提供することが、含まれるPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/108646/1/imhj21465.pd

Data driven optimal filtering for phase and frequency of noisy oscillations: application to vortex flowmetering

A new method for extracting the phase of oscillations from noisy time series is proposed. To obtain the phase, the signal is filtered in such a way that the filter output has minimal relative variation in the amplitude (MIRVA) over all filters with complex-valued impulse response. The argument of the filter output yields the phase. Implementation of the algorithm and interpretation of the result are discussed. We argue that the phase obtained by the proposed method has a low susceptibility to measurement noise and a low rate of artificial phase slips. The method is applied for the detection and classification of mode locking in vortex flowmeters. A novel measure for the strength of mode locking is proposed.Comment: 12 pages, 10 figure

Self-adjoint Lyapunov variables, temporal ordering and irreversible representations of Schroedinger evolution

In non relativistic quantum mechanics time enters as a parameter in the Schroedinger equation. However, there are various situations where the need arises to view time as a dynamical variable. In this paper we consider the dynamical role of time through the construction of a Lyapunov variable - i.e., a self-adjoint quantum observable whose expectation value varies monotonically as time increases. It is shown, in a constructive way, that a certain class of models admit a Lyapunov variable and that the existence of a Lyapunov variable implies the existence of a transformation mapping the original quantum mechanical problem to an equivalent irreversible representation. In addition, it is proved that in the irreversible representation there exists a natural time ordering observable splitting the Hilbert space at each t>0 into past and future subspaces.Comment: Accepted for publication in JMP.

Interpolation and harmonic majorants in big Hardy-Orlicz spaces

Free interpolation in Hardy spaces is caracterized by the well-known Carleson condition. The result extends to Hardy-Orlicz spaces contained in the scale of classical Hardy spaces $H^p$, $p>0$. For the Smirnov and the Nevanlinna classes, interpolating sequences have been characterized in a recent paper in terms of the existence of harmonic majorants (quasi-bounded in the case of the Smirnov class). Since the Smirnov class can be regarded as the union over all Hardy-Orlicz spaces associated with a so-called strongly convex function, it is natural to ask how the condition changes from the Carleson condition in classical Hardy spaces to harmonic majorants in the Smirnov class. The aim of this paper is to narrow down this gap from the Smirnov class to ``big'' Hardy-Orlicz spaces. More precisely, we characterize interpolating sequences for a class of Hardy-Orlicz spaces that carry an algebraic structure and that are strictly bigger than $\bigcup_{p>0} H^p$. It turns out that the interpolating sequences are again characterized by the existence of quasi-bounded majorants, but now the weights of the majorants have to be in suitable Orlicz spaces. The existence of harmonic majorants in such Orlicz spaces will also be discussed in the general situation. We finish the paper with an example of a separated Blaschke sequence that is interpolating for certain Hardy-Orlicz spaces without being interpolating for slightly smaller ones.Comment: 19 pages, 2 figure
