Projective prime ideals and localisation in pi-rings

The results here generalise [2, Proposition 4.3] and [9, Theorem 5.11]. We shall prove the following. THEOREM A. Let R be a Noetherian PI-ring. Let P be a non-idempotent prime ideal of R such that PR is projective. Then P is left localisable and RP is a prime principal left and right ideal ring. We also have the following theorem. THEOREM B. Let R be a Noetherian PI-ring. Let M be a non-idempotent maximal ideal of R such that MR is projective. Then M has the left AR-property and M contains a right regular element of R

Design and testing of the navigation model for three axis stabilized earth oriented satellites applied to the ATS-6 satellite image data base

An earth edge methodology has been developed to account for the relative attitude changes between successive ATS-6 images which allows reasonable high quality wind sets to be produced. The method consists of measuring the displacements of the right and left infrared earth edges between successive ATS-6 images as a function of scan line; from these measurements the attitude changes can be deduced and used to correct the apparent cloud displacement measurements. The wind data sets generated from ATS-6 using the earth-edge methodology were compared with those derived from the SMS-1 images (and model) covering the same time period. Quantitative comparisons for low level trade cumuli were made at interpolated uniformly spaced grid points and for selected individual comparison clouds. Selected individual comparison clouds, the root-mean-square differences for the U and V components were 1.0 and 1.2 meters per second with a maximum wind direction difference of 15 deg

User manual and programmer reference manual for the ATS-6 navigation model AOIPS and McIDAS versions, part 2

Development of a navigation system for a given satellite is reported. An algorithm for converting a satellite picture element location to earth location and vice versa was defined as well as a procedure for measuring the set of constants needed by the algorithm. A user manual briefly describing the current version of the navigation model and how to use the computer programs developed for it is presented

America is not losing its religion – population trends mean thatit is simply becoming more religiously diverse.

A recent Pew study found that there has been an increase in the number of Americans who claim to have ‘no-religion’. Does this mean that religion in the U.S. is on the way out? In new research which examines data from three national surveys, R. Khari Brown, Robert Joseph Taylor, and Linda M. Chatters find that African Americans and African Caribbean Americans are less likely than Non-Hispanic Whites, Hispanic Americans, and Asian Americans to identify as non-religious, with the latter group the most likely to identify as non-religious. They write that the recent shifts in religious affiliation may have less to do with Americans abandoning religion to America shifting towards increasing religious diversity

Health, disability, psychological well-being, and depressive symptoms among older African American women

This study examines the demographic correlates of psychological well-being (i.e., happiness and life satisfaction) and mental health (i.e., depressive symptoms and serious psychological distress) among older African American women. Addition- ally, the relationships between self-rated physical and oral health and disability and psychological well-being and mental health are explored. Analyses are based on a nationally representative sample of older African American women from the National Survey of American Life. Results indicate that psychological well-being (i.e., life satisfaction and happiness) and mental health (i.e., depressive symptoms and serious psychological distress) are associated with specific demographic factors. In addition, self-rated health and limited mobility due to disability exerted significant influences on psychological well-being, depressive symptoms, and psychological distress. Findings are discussed in relation to prior research on demographic and health factors and their unique associations with well-being and mental status among older African American women.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/107409/1/Health, Disability, Psychological Well-Being, and Depressive Symptoms among Older African American Women.pdfDescription of Health, Disability, Psychological Well-Being, and Depressive Symptoms among Older African American Women.pdf : Main articl

The relationship between obsessive-compulsive disorder and religious faith: Clinical characteristics and implications for treatment

This paper explores the relationship between religion and obsessive–compulsive dis- order (OCD), with particular interest in religion’s possible influence in the development of OCD and its impact on treatment outcome. The paper begins with a review of theoretical and research literatures concerning religious involvement, research evidence linking religious involvement and physical and mental health, and theoretical linkages supporting both positive and negative religious effects on health. Following this, we provide a general overview and description of OCD and information concerning the prevalence and incidence of religiously based OCD. Next, extant research linking religion and OCD is presented. Information relevant to the clinical treatment of OCD with religious content is discussed. Finally, practice implications for clinicians and clergy are provided.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/107413/1/2011-11166-001.pdfDescription of 2011-11166-001.pdf : Main articl

Comorbid mood and anxiety disorders, suicidal behavior, and substance abuse among Black Caribbeans in the U.S.A.

The purpose of this study was to examine nativity and country of origin differences in comorbid mood (major depressive disorder, dysthymia, and bipolar I and II disorders) and anxiety (post-traumatic stress disorder, panic disorder, agora- phobia, social phobia, generalized anxiety disorder, and obsessive compulsive disor- der) disorders among Black Caribbeans in the U.S.A. The paper also examines the relationship between comorbid psychiatric disorders and substance abuse disorders and suicidal behavior. Data are taken from the Black Caribbean sub-sample (N0 1,621) of the National Survey of American Life. Multinomial logistic regression and logistic regression analysis are used and odd ratios, relative risk ratios, and 95 % confidence intervals are presented. Seven percent (7.19 %) of respondents had comorbid mood and anxiety disorders, 8.66 % had a mood disorder only, and 11.46 % had an anxiety disorder only. First-generation Black Caribbeans were less likely than US-born respondents to have a lifetime mood or anxiety disorder and also less likely to have a lifetime substance disorder or a lifetime suicidal attempt. Black Caribbean men were more likely than Black Caribbean women to: (1) have anxiety disorders only versus neither mood or anxiety disorders, (2) to have a substance disorder, and (3) to have had a suicidal attempt. Lastly, Black Caribbeans with both mood and anxiety disorders have significantly higher rates of mental health services utilization. These and other findings are discussed in detail.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/107408/1/10.1007_s12111-012-9237-y.pdfDescription of 10.1007_s12111-012-9237-y.pdf : Main articl

Religious Participation and DSM IV Major Depressive Disorder Among Black Caribbeans in the United States

This study examines the relationship between religious involvement and 12-month and lifetime DSM-IV major depressive disorder (MDD) within a nationally rep- resentative sample of Black Caribbean adults. MDD was assessed using the DSM-IV World Mental Health Com- posite International Diagnostic Interview (WMH-CIDI). Religious involvement included measures of religious coping, organizational and nonorganizational involvement, and subjective religiosity. Study findings indicate that religious involvement is associated with 12-month and lifetime prevalence of MDD. Multivariate relationships between religious involvement and MDD indicate lower prevalence of 12-month and lifetime MDD among persons who use religious coping and characterize themselves as being religious (for lifetime prevalence only); persons who frequently listen to religious radio programs report higher lifetime MDD. Lower rates of 12-month and lifetime MDD are noted for persons who attend religious services at least once a week (as compared to both higher and lower levels of attendance), indicating a curvilinear relationship. The findings are discussed in relation to previous research on religion and mental health concerns, conceptual models of the role of religion in mental health (e.g., prevention, resource mobilization) that specify multiple and often divergent pathways and mechanisms of religious effects on health outcomes, and the role of religion among Caribbean Blacks.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/107411/1/Religious Participation and DSM IV Major Depressive Disorder Among Black Caribbeans in the United States.pdfDescription of Religious Participation and DSM IV Major Depressive Disorder Among Black Caribbeans in the United States.pdf : Main articl

The long-term (24-month) effect on health and well-being of the Lifestyle Matters community-based intervention in people aged 65 years and over: a qualitative study

Objectives To assess the long-term effect on health and well-being of the Lifestyle Matters programme. Design Qualitative study of a subset of intervention arm participants who participated in the Lifestyle Matters randomised controlled trial (RCT). Setting The intervention took place at community venues within two sites in the UK. Participants A purposeful sample of 13 participants aged between 66 and 88 years from the intervention arm of the RCT were interviewed at 24 months post randomisation. Interviews aimed to understand how participants had used their time in the preceding 2 years and whether the intervention had any impact on their lifestyle choices, participation in meaningful activities and well-being. Intervention Lifestyle Matters is a 4-month occupational therapy intervention, consisting of group and individual sessions, designed to enable community living older people to make positive lifestyle choices and participate in new or neglected activities through increasing self-efficacy. Results Interviews revealed that the majority of interviewed participants were reportedly active at 24 months, with daily routines and lifestyles not changing significantly over time. All participants raised some form of benefit from attending Lifestyle Matters, including an improved perspective on life, trying new hobbies and meeting new friends. A number of intervention participants spoke of adapting to their changing circumstances, but there were significant and lasting benefits for 2 of 13 intervention participants interviewed. Conclusion The majority of those who experienced the Lifestyle Matters intervention reported minor benefits and increases in self-efficacy, but they did not perceive that it significantly improved their health and well-being. The two participants who had experienced major benefits also reported having had life-changing events, suggesting that this intervention is most effective at the time when lifestyle has to be reconsidered if mental well-being is to be sustaine

Subjective well-being of older African Americans with DSM IV psychiatric disorders

This study examined demographic and mental health correlates of subjective well-being (i.e., life satisfaction, happiness) using a national sample of older African Americans with psychiatric disorders. We used a subsample of 185 African Americans, 55 and older with at least one of thirteen lifetime psychiatric disorders from The National Survey of American Life: Coping with Stress in the Twenty-first Century. The findings indicated that among this population of older adults who had a lifetime psychiatric dis- order, having a lifetime suicidal ideation was associated with life satisfaction but not happiness. Further, having a 12-month anxiety disorder or a lifetime suicidal ideation was not associated with happiness. Having a 12-month mood disorder, however, was negatively associated with an individual’s level of happiness, as well as their life satisfaction. Additionally, there were two significant interactions. Among men, employment was pos- itively associated with life satisfaction, and marriage was associated with higher levels of happiness among men but not women. The overall pattern of findings reflects both simi- larities and departures from prior research confirming that well-being evaluations are associated with multiple factors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/107412/1/art%3A10.1007%2Fs10902-013-9470-7(1).pdfDescription of art%3A10.1007%2Fs10902-013-9470-7(1).pdf : Main articl
