Submaximal Treadmill Exercise Test to Predict VO2max in Fit Adults

This study was designed to develop a single-stage submaximal treadmill jogging (TMJ) test to predict VO₂max in fit adults. Participants (N?=?400; men?=?250 and women?=?150), ages 18 to 40 years, successfully completed a maximal graded exercise test (GXT) at 1 of 3 laboratories to determine VO₂max. The TMJ test was completed during the first 2 stages of the GXT. Following 3 min of walking (Stage 1), participants achieved a steady-state heart rate (HR) while exercising at a comfortable self-selected submaximal jogging speed at level grade (Stage 2). Gender, age, body mass, steady-state HR, and jogging speed (mph) were included as independent variables in the following multiple linear regression model to predict VO₂max (R?=?0.91, standard error of estimate [SEE]?=?2.52 mL?·?kg^?1?·?min^?1): VO₂max (mL?·?kg^?1?·?min^?1)?=?58.687?+?(7.520 × Gender; 0?=?woman and 1?=?man)?+?(4.334 × mph) ? (0.211 × kg) ? (0.148 × HR) ? (0.107 × Age). Based on the predicted residual sum of squares (PRESS) statistics (R_PRESS?=?0.91, SEE _PRESS?=?2.54 mL?·?kg^?1?·?min^?1) and small total error (TE; 2.50 mL?·?kg^?1?·?min^?1; 5.3% of VO₂max) and constant error (CE; ?0.008 mL?·?kg^?1?·?min^?1) terms, this new prediction equation displays minimal shrinkage. It should also demonstrate similar accuracy when it is applied to other samples that include participants of comparable age, body mass, and aerobic fitness level. This simple TMJ test and its corresponding regression model provides a relatively safe, convenient, and accurate way to predict VO₂max in fit adults, ages 18 to 40 years.     

Factors Contributing to Scholarly Productivity of Assistant Professors in Counseling

Doctoral research training and faculty departmental research culture were explored in relation to research interest, self‐efficacy, and productivity among 49 counselor education assistant professors. Doctoral research training environment consistently held strong positive relationships with research interest and self‐efficacy, suggesting that a solid foundation in research at the doctoral level is imperative for initial research productivity.     

Testing,Testing: Teacher assessment in England

In England there has been a marked increase in the assessment of teachers, culminating in the introduction of a performance management policy for schools that calibrates the occupation of teaching from the cradle to the grave. In this article, we raise a number of issues about the consequences of this policy for teachers and teaching in relation to the value system underpinning it, its likely impact on issues of equity and social justice, its implications for accountability and governance, and its potential for reshaping the culture of teaching in ways that will impact negatively on the nature of future community and social relations.     

LITERACY AND ELDERS: WHAT WE KNOW AND WHAT WE NEED TO KNOW

Little research has been done on the literacy needs and interests of elders. Consequently, many programs of literacy training for elders are based upon inadequate and inaccurate information. The authors review recent literature about literacy and the aged and offer some suggestions for future investigations. They maintain that there is a need for empirical research into the perceptions of reading and writing held by the elderly themselves. Specifically, this research should: (1) assess the reading/writing needs and interests of the elderly; and (2) examine what effect societal expectations of the elderly have on their reading/writing behavior and interests.     

Cognitive Stimulation as a Mechanism Linking Socioeconomic Status With Executive Function: A Longitudinal Investigation

Executive functions (EF), including working memory, inhibition, and cognitive flexibility, vary as a function of socioeconomic status (SES), with children from economically disadvantaged backgrounds having poorer performance than their higher SES peers. Using observational methods, we investigated cognitive stimulation in the home as a mechanism linking SES with EF. In a sample of 101 children aged 60–75 months, cognitive stimulation fully mediated SES-related differences in EF. Critically, cognitive stimulation was positively associated with the development of inhibition and cognitive flexibility across an 18-month follow-up period. Furthermore, EF at T1 explained SES-related differences in academic achievement at T2. Early cognitive stimulation—a modifiable factor—may be a desirable target for interventions designed to ameliorate SES-related differences in cognitive development and academic achievement.     

Bringing installation art to reconnaissance to share values and generate action

The English education system has recently seen something of a revival of enthusiasm for the use of research both to develop educational practices and to gather evidence about their effectiveness. These initiatives often present action research as a model of individual problem-solving, which, we argue, communicates a limited conception of action research. In this paper we propose an alternative to this ‘problem-solving’ conception of action research that acknowledges the complex, messy nature of action research through the use of arts installations. Specifically, we present the reconnaissance phase of a project which brought together a partnership comprising a water heritage museum, university staff, teachers and artists. A pedagogical adaptation of contemporary installation art theory and practice fostered the exploration of individual and collective understandings of water, and also established a shared approach to curriculum development and ownership of the project among all participants. We propose that this creative practice enhanced and changed the process of reconnaissance; it allowed the group to establish and share commitments to the value of water conservation and generated a wide range of options for our action research.     

Early Childhood Education and Public School Principals: Constructing a Relationship

This article discusses the results of a statewide study of elementary school principals' perceptions of barriers to the establishment of preschool programs in the public school setting. The study was conducted in response to current federal an: state mandates requiring school districts to provide comprehensive services for developmentally delayed and at-risk preschoolers, as well as other preschool populations. A representative sample of principals responded to a comprehensive questionnaire that included principals' knowledge of child development and their attitudes about establishing programs for preschool children in the public school sector. Results indicate that, across the board, elementary principals foresee major barriers to the effective implementation of such federal mandates as Public Law 99-457. Specific barriers are identified and discussed. Implications for practice and policy are presented.
