Protein needs of older adults engaged in resistance training: a review

Protein recommendations by some professional organizations for young adults engaged in resistance training (RT) are higher than the recommended dietary allowance (RDA), but recommendations for resistance-training older adults (>50 years old) are not well characterized. Some argue that the current RDA is adequate, but others indicate increased protein needs. Although concerns have been raised about the consequences of high protein intake, protein intake above the RDA in older adults is associated with increased bone-mineral density when calcium intake is adequate and does not appear to compromise renal health in older individuals with normal renal function. Individual protein needs for older adults in RT are likely highly variable according to health and training regimen, but an intake of 1.0-1.3 g x kg(-1) x day(-1) should adequately and safely meet the needs of older adults engaged in RT, provided that their energy needs are met.     

The Social Participation of Blacks: A Proposed Synthesis of Two Competing Theories

Discrepant findings have typified the research concerning the social participation of blacks in America. The bulk of the findings would seem to posit three competing theories, one emphasizing low participation levels on the part of blacks, and the later two emphasizing high levels of social participation. These theories are examined and a synthesis of the "isolation" and "compensation" models is proposed. By examining both formal and informal types of social participation on the part of blacks, it is argued that both theories are viable toward explaining variation within black participation levels in particular and toward mediating the discrepant findings as they have been previously offered in general. Some support is found for such a proposed synthesis.     

Cumulative sum (cusum) control schemes

Cumulative Sum (CUSUM) quality control schemes are becoming widely used i n industry because they are powerful, versatile, and easy to use. They cumulate recent process data to quickly detect out-of-control situations. They also serve as a powerful diagnostic tool. There are now more than 10,000 CUSUM control schemes in use daily in Du Pont. This paper describes design and implementation procedures for CUSUM control schemes with emphasison properties that are recorded as counts. The paper will describe recent developments which make CUSUM procedures more useful and more powerful.

The recent developments described are: Fast Initial Response (FIR) CUSUM which gives extra sensitivity to out-of-control situations at start up or after a(possiblyin effective)control action.

A Combined She whart-CUSUM which combines the key features

of CUSUM schemes and She whart Schemes by adding She whart Control Limits to a CUSUM scheme.

ROBUST CUSUM schemes which are no tunduly influenced by a few outliers or fliers occurring in the stream of data.

The philosophy of continual improvement of aprocessisvery compatible with CUSUM procedures.As CUSUM procedures give much more responsive control,a CUSUM signal does notmean that the process is producing bad product.Rather it means that action should be taken sothat the process does not produce bad product.     

Conditional Euro Area Sovereign Default Risk

We propose an empirical framework to assess the likelihood of joint and conditional sovereign default from observed CDS prices. Our model is based on a dynamic skewed-t distribution that captures all salient features of the data, including skewed and heavy-tailed changes in the price of CDS protection against sovereign default, as well as dynamic volatilities and correlations that ensure that uncertainty and risk dependence can increase in times of stress. We apply the framework to euro area sovereign CDS spreads during the euro area debt crisis. Our results reveal significant time-variation in distress dependence and spill-over effects for sovereign default risk. We investigate market perceptions of joint and conditional sovereign risk around announcements of Eurosystem asset purchases programs, and document a strong impact on joint risk.     

Variation in American Sign Language: The case of DEAF

Variation in sign languages has been a neglected area of research in sociolinguistics. This article, part of a large-scale study of variation in American Sign Language (ASL) designed to redress that situation, examines variation in the form of the sign DEAF, which can be produced by moving the forefinger from ear to chin, from chin to ear, or by contacting the lower cheek. Multivariate analysis of more than 1600 tokens of DEAF extracted from sociolinguistic interviews with 207 signers residing in seven regions of the United States shows that both linguistic and social factors significantly constrain choice among the three variants. The analysis also illustrates patterns that parallel variation in spoken languages. However, despite the similarities to variation in spoken languages, we suggest that results for the regional patterning of variation are best explained by reference to Deaf history, particularly to changes in the status and use of ASL in deaf education.

The immigrant experience: Houstonians’ family attitudes and behaviors

ABSTRACT

Although there is extensive scholarship that examines differences in family behaviors and attitudes between whites and blacks, there are very few studies that examine these differences across whites, blacks, Latinos, and Asians in the United States. In the current study, we do so by examining data from the 2011 Houston Area Survey. We explore Houstonians’ likelihood of engaging in interracial relationships, attitudes toward working mothers, and attitudes toward same-sex marriage. Houston was selected as the target of the study given its rise as the most racially and ethnically diverse metropolitan area in the nation. Non-white Houstonians are more likely to date members of other racial/ethnic groups. With regard to attitudes toward working mothers, only Latino and Asian immigrants hold less accepting views than whites. Finally, the results with regard to same-sex marriage equality suggest that increased migration and diversity within Houston could hasten social change and acceptance.     

Considerations on the ‘Replication Problem’ in Sociology

We re-examine the so-called “replication problem” in sociology—a scarcity of published studies dedicated to reproducing findings from prior research. We do this in part by considering the larger epistemological traditions of the natural sciences and humanities. We make three primary arguments: that (1) replication studies are more prevalent than is commonly perceived, (2) calls for and discussions of replication do not attend enough to issues of theory, and (3) we should reconsider as a discipline how we evaluate replications. In developing this third argument, we draw on the concept of episteme, discussing two epistemes that concurrently exist in sociology: the scientific project and the aesthetic object. The former overlaps with approaches to knowledge growth in the natural sciences, the latter with the humanities. We propose that sociology is situated between these extremes, presenting unique challenges for replication research. In particular, nuanced considerations of replications in sociology foreclose any simplistic accounts of a replication problem in the discipline.
