National level promotion of physical activity: results from England's ACTIVE for LIFE campaign.

STUDY OBJECTIVE: To assess the impact of a national campaign on awareness of the campaign, change in knowledge of physical activity recommendations and self reported physical activity. DESIGN: three year prospective longitudinal survey using a multi-stage, cluster random probability design to select participants. SETTING: England. PARTICIPANTS: A nationally representative sample of 3189 adults aged 16-74 years. MAIN OUTCOME MEASURES: Awareness of the advertising element of the campaign, changes in knowledge of physical activity recommendations for health and self reported physical activity. RESULTS: 38% of participants were aware of the main advertising images, assessed six to eight months after the main television advertisement. The proportion of participants knowledgeable about moderate physical activity recommendations increased by 3.0% (95% CI: 1.4%, 4.5%) between waves 1 and 2 and 3.7% (95% CI: 2.1%, 5.3%) between waves 1 and 3. The change in proportion of active people between baseline and waves 1 and 2 was -0.02 (95% CI: -2.0 to +1.7) and between waves 1 and 3 was -9.8 (-7.9 to -11.7). CONCLUSION: The proportion of participants who were knowledgeable about the new recommendations, increased significantly after the campaign. There was however, no significant difference in knowledge by awareness of the main campaign advertisement. There is no evidence that ACTIVE for LIFE improved physical activity, either overall or in any subgroup

Interview with John and Marcia Diamond by Mike Hastings

Biographical NoteJohn Nathan Diamond was born on November 12, 1954, in Bangor, Maine. His father, Nathan Diamond, was a musician and a teacher, and his mother, Eleanor Diamond, was active in the community and in local politics. John followed politics with his parents, who were registered Republicans until 1978 when they changed their party affiliation and became Democrats. As a teenager, John volunteered for Elmer Violette and Bill Hathaway in 1972. After graduating from Bangor High School, he attended the University of Maine, graduating in 1977. He became involved in the Carter and Muskie campaigns of 1976. He worked for the Lewiston Sun-Journal after college, covering local politics, and then took a job running Jim Henderson’s primary campaign of 1978. He worked for Bill Hathaway in the general election that year and then took a job as a staffer in the Maine state House majority office. In 1980, he was elected to a House seat representing Bangor, and in 1982 he was reelected unopposed. Not having to campaign much for himself, he worked for Mitchell’s 1982 campaign. He met Marcia in 1985 and they were married September 13, 1986. They have two children and live in Bangor, Maine, where John worked for the University of Maine system as executive director of external affairs at the time of this interview. Marcia LaRochelle Diamond was born on June 8, 1962, in Bath, Maine, to Mary Sullivan LaRochelle and Neil LaRochelle. Marcia was the fourth of six children. Her father was a principal in the Bath school system, and he ran a family business called LaRochelle and Sons Market Gardens. Her mother encouraged her to get involved in politics in order to broaden her experience beyond being a teacher, which was the career that Marcia aspired to achieve. Marcia attended the University of Maine, Farmington, graduating early in order to intern in Mitchell’s office in Washington D.C. She began in the press office, and when the term of her internship was over she was hired as assistant press secretary. After a few years, she moved back to Maine to provide Senator Mitchell’s office with a press presence at home. After marrying John and finding that Mitchell’s seat was safe for the 1988 campaign, Marcia retired from her political career and pursued teaching. She began teaching sixth grade at East Corinth School and became involved in the Odyssey of the Mind program. After a hiatus rearing her children, she returned to teaching at St. Mary’s Catholic School, which merged with St. John’s Catholic School in 2000 to become All Saints Catholic School, where Marcia served as principal at the time of this interview. SummaryInterview includes discussions of: growing up in Maine; the 1972 election; the University of Maine; the 1976 election; John’s running for the legislature in 1980; the Penobscot County Democrats; taking John’s seventy-five year old grandmother to see President Carter during his visit to Bangor in 1980; Bangor in the 1960s and 1970s; Marcia’s connection with Gayle Cory; Marcia’s internship in Mitchell’s Senate office in Washington, D.C. and subsequent work in Mitchell’s press office; Marcia’s decision to return to Maine; how John and Marcia met, their first date, and John’s proposal; how John got involved in Mitchell’s 1982 campaign; the field operation in 1982; how Mitchell developed his public persona; forecasting that nuclear and environmental issues would become crucial issues in the 1980s; the campaign strategy of following up on phone calls with letters about issues relevant to the phone conversation; the Fourth of July Parade in Bangor as a turning point in the 1982 campaign; election night, 1982; Marcia’s involvement with Odyssey of the Mind; John’s and Marcia’s small business; Marcia’s career in education; John’s work with Maine Public Broadcasting; how Marcia learned from Gayle Cory to never take “no” for an answer; and the forgotten luggage story

Stabilization, pointing and command control of a balloon-borne 1-meter telescope

A 1-meter balloon-borne telescope has been constructed and flown to observe far-infrared radiation from celestial sources. The attitude control systems must perform to the diffraction limit of the telescope for stabilization and have positioning capability for source acquisition. These and associated systems are discussed in detail, as is the command control of the payload as a whole

Associations of womens position in the household and food insecurity with family planning use in Nepal.

BACKGROUND: Women in Nepal have low status, especially younger women in co-resident households. Nepal also faces high levels of household food insecurity and malnutrition, and stagnation in uptake of modern family planning methods. OBJECTIVE: This study aims to understand if household structure and food insecurity interact to influence family planning use in Nepal. METHODS: Using data on married, non-pregnant women aged 15-49 with at least one child from the Nepal 2011 Demographic and Health Survey (N = 7,460), we explore the relationship between womens position in the household, food insecurity as a moderator, and family planning use, using multi-variable logistic regressions. We adjust for household and individual factors, including other status-related variables. RESULTS: In adjusted models, living in a food insecure household and co-residing with in-laws either with no other daughter-in-laws or as the eldest or youngest daughter-in-law (compared to not-co-residing with in-laws) are all associated with lower odds of family planning use. In the interaction model, younger-sisters-in-law and women co-residing with no sisters-in-law in food insecure households have the lowest odds of family planning use. CONCLUSION: This study shows that household position is associated with family planning use in Nepal, and that food insecurity modifies these associations-highlighting the importance of considering both factors in understanding reproductive health care use in Nepal. Policies and programs should focus on the multiple pathways through which food insecurity impacts womens reproductive health, including focusing on women with the lowest status in households

Multi-Period Trading via Convex Optimization

We consider a basic model of multi-period trading, which can be used to evaluate the performance of a trading strategy. We describe a framework for single-period optimization, where the trades in each period are found by solving a convex optimization problem that trades off expected return, risk, transaction cost and holding cost such as the borrowing cost for shorting assets. We then describe a multi-period version of the trading method, where optimization is used to plan a sequence of trades, with only the first one executed, using estimates of future quantities that are unknown when the trades are chosen. The single-period method traces back to Markowitz; the multi-period methods trace back to model predictive control. Our contribution is to describe the single-period and multi-period methods in one simple framework, giving a clear description of the development and the approximations made. In this paper we do not address a critical component in a trading algorithm, the predictions or forecasts of future quantities. The methods we describe in this paper can be thought of as good ways to exploit predictions, no matter how they are made. We have also developed a companion open-source software library that implements many of the ideas and methods described in the paper

Conserved visual capacity of rats under red light

Recent studies examine the behavioral capacities of rats and mice with and without visual input, and the neuronal mechanisms underlying such capacities. These animals are assumed to be functionally blind under red light, an assumption that might originate in the fact that they are dichromats who possess ultraviolet and green but not red cones. But the inability to see red as a color does not necessarily rule out form vision based on red light absorption. We measured Long-Evans rats’ capacity for visual form discrimination under red light of various wavelength bands. Upon viewing a black and white grating, they had to distinguish between two categories of orientation, horizontal and vertical. Psychometric curves plotting judged orientation versus angle demonstrate the conserved visual capacity of rats under red light. Investigations aiming to explore rodent physiological and behavioral functions in the absence of visual input should not assume red-light blindness
