The Effectiveness Of Metamemory Instruction In Promoting Generalisation Of The Keyword Mnemonic Strategy: A Developmental Study

The effectiveness of an instructional programme, consisting of strategy training supplemented by metamemory instruction in promoting generalisation of the keywod mnemonic strategy, was assessed. Three experiments were conducted to investigate three specific issues. In Experiment 1, the effectiveness of the metamemory instructional programme in promoting generalisation was compared to that of other instructional routines. Eleven-year-old students learned a list of cities paired with their products. Children in the four experimental conditions were instructed in the use of the keyword strategy to learn city-product pairs. In addition, children in three of the experimental conditions received one of the following types of supplementary instruction: Metamemory instruction, experience with the strategy on a variety of memory tasks, or metamemory instruction plus experience training. Following learning on the city-product task, all the subjects were asked to learn a list of Latin nouns and their English translations. Children who received a metamemory component in instruction demonstrated the most successful generalisation of the keyword strategy. In Experiment 2, the effectiveness of the metamemory instructional programme in promoting maximal generalisation was assessed. Eleven-year-old subjects learned the city-product and Latin-English lists used in Experiment 1. The performance of children who received either (1) keyword strategy instruction with city-product pairs, or (2) strategy instruction plus metamemory training was compared to the performance of children instructed in keyword strategy use with both city-product and Latin-English pairs. Children who received metamemory instruction achieved maximal generalisation, demonstrating comparable recall performance and reporting using the strategy as frequently as children directly instructed in the use of the technique on the generalisation task. In Experiment 3, the issues addressed in Experiments 1 and 2 with younger children were readdressed for 19-year-old students-both in a single experiment. For these older subjects, keyword strategy training with city-product pairs was sufficient to promote maximal generalisation of the technique to the Latin-English task. Implications for instructional research are discussed

A Paradox in Employment: The Contradiction That Exists between Immigration Laws and Outsourcing Practices, and Its Impact on the Legal and Illegal Minority Working Classes

The drastic distinctions between the United States’ immigration and outsourcing policies have created a system where American companies are able to send unlimited jobs overseas, yet, have very restricted ability to bring workers to domestic offices and factories. Restrictive immigration policies seek to protect American jobs, while liberal outsourcing regulations permit, and encourage, employers to send jobs outside of the United States. As a result, the United States’ outsourcing policy sabotages the purpose of American immigration laws. The uncertainty of the contradiction between immigration and outsourcing policy may be the cause of unusually high unemployment numbers, particularly in the minority working class. This paper will argue that through application, the United States’ immigration and outsourcing policies are contradictory in their goals and application. Furthermore, this paper will assert that the United States’ outsourcing policy undermines employment immigration policy, and indirectly facilitates unemployment and economic despair. Lastly, this paper asserts that an illegal immigration working class is present in the United States because of the interplay of immigration and outsourcing policies

Whole-fat or reduced-fat dairy product intake, adiposity, and cardiometabolic health in children: A systematic review

Dietary guidelines commonly recommend that children aged \u3e2 y consume reduced-fat dairy products rather than regular- or whole-fat dairy. In adults, most studies have not found the consumption of whole-fat dairy products to be associated with increased cardiometabolic or adiposity risk. Associations in children could differ due to growth and development. We systematically reviewed the literature in indexed, peer-reviewed journals to summarize pediatric studies (children aged from 2 to 18 y) assessing associations between whole- and reduced-fat dairy intake and measures of adiposity as well as biomarkers of cardiometabolic disease risk, including the serum lipid profile, blood pressure, low-grade chronic inflammation, oxidative stress, and measures of glucose homeostasis. For the purposes of this review, a “whole-fat” dairy product was defined as a product with the natural fat content, whereas a “reduced-fat” dairy product was defined as a product with some or all of the fat removed (including “low-fat” and “skim” versions). A total of 29 journal articles met our criteria for inclusion. The majority were conducted in the United States and were prospective or cross-sectional observational studies, with only 1 randomized controlled trial. Studies were consistent in reporting that whole-fat dairy products were not associated with increased measures of weight gain or adiposity. Most evidence indicated that consumption of whole-fat dairy was not associated with increased cardiometabolic risk, although a change from whole-fat to reduced-fat dairy improved outcomes for some risk factors in 1 study. Taken as a whole, the limited literature in this field is not consistent with dietary guidelines recommending that children consume preferably reduced-fat dairy products. High-quality randomized controlled trials in children that directly compare the effects of whole-fat compared with reduced-fat dairy intake on measures of adiposity or biomarkers of cardiometabolic disease risk are needed to provide better quality evidence in this area

Online video instruction on hand expression of colostrum in pregnancy is an effective educational tool

The use of antenatal colostrum expression in the weeks prior to birth may help improve long-term breastfeeding, but few large-scale studies exist. Typically, antenatal colostrum expression instruction relies on face-to-face education, making large interventions costly. We aimed to determine whether an expert online instructional video can improve knowledge and confidence around antenatal colostrum expressing. Pregnant women were asked to complete a questionnaire pre- and post-watching the instructional video online. Ninety five pregnant women completed both pre- and post-questionnaires. Total antenatal colostrum expression knowledge scores improved after watching the video, from a mean of 3.05 ± 1.70 correct out of a maximum of 7, to 6.32 ± 0.76 (p \u3c 0.001). Self-reported confidence around hand expressing in pregnancy also improved from an average ranking of not confident (2.56 ± 1.17, out of a possible 5) to confident (4.32 ± 0.80, p \u3c 0.001). Almost all women (98%) reported that they would recommend the video to a friend or family member if antenatal colostrum expression was suggested by their healthcare provider. Findings suggest that the use of an online expert video is an acceptable and effective way to educate pregnant women in antenatal colostrum expression

Tackling overweight and obesity: Does the public health message match the science?

Background: Despite the increasing understanding of the mechanisms relating to weight loss and maintenance, there are currently no validated public health interventions that are able to achieve sustained long-term weight loss or to stem the increasing prevalence of obesity in the population. We aimed to examine the models of energy balance underpinning current research about weight-loss intervention from the field of public health, and to determine whether they are consistent with the model provided by basic science. EMBASE was searched for papers published in 2011 on weight-loss interventions. We extracted details of the population, nature of the intervention, and key findings for 27 articles.Discussion: Most public health interventions identified were based on a simple model of energy balance, and thus attempted to reduce caloric consumption and/or increase physical activity in order to create a negative energy balance. There appeared to be little consideration of homeostatic feedback mechanisms and their effect on weight-loss success. It seems that there has been a lack of translation between recent advances in understanding of the basic science behind weight loss, and the concepts underpinning the increasingly urgent efforts to reduce excess weight in the population.Summary: Public health weight-loss interventions seem to be based on an outdated understanding of the science. Their continued failure to achieve any meaningful, long-term results reflects the need to develop intervention science that is integrated with knowledge from basic science. Instead of asking why people persist in eating too much and exercising too little, the key questions of obesity research should address those factors (environmental, behavioral or otherwise) that lead to dysregulation of the homeostatic mechanism of energy regulation. There is a need for a multidisciplinary approach in the design of future weight-loss interventions in order to improve long-term weight-loss success

Comparison of multiple and novel measures of dietary glycemic carbohydrate with insulin resistant status in older women

Background: Previous epidemiological investigations of associations between dietary glycemic intake and insulin resistance have used average daily measures of glycemic index (GI) and glycemic load (GL). We explored multiple and novel measures of dietary glycemic intake to determine which was most predictive of an association with insulin resistance. Methods: Usual dietary intakes were assessed by diet history interview in women aged 42-81 years participating in the Longitudinal Assessment of Ageing in Women. Daily measures of dietary glycemic intake (n = 329) were carbohydrate, GI, GL, and GL per megacalorie (GL/Mcal), while meal based measures (n = 200) were breakfast, lunch and dinner GL; and a new measure, GL peak score, to represent meal peaks. Insulin resistant status was defined as a homeostasis model assessment (HOMA) value of \u3e3.99; HOMA as a continuous variable was also investigated. Results: GL, GL/Mcal, carbohydrate (all P \u3c 0.01), GL peak score (P = 0.04) and lunch GL (P = 0.04) were positively and independently associated with insulin resistant status. Daily measures were more predictive than meal-based measures, with minimal difference between GL/Mcal, GL and carbohydrate. No significant associations were observed with HOMA as a continuous variable. Conclusion: A dietary pattern with high peaks of GL above the individual’s average intake was a significant independent predictor of insulin resistance in this population, however the contribution was less than daily GL and carbohydrate variables. Accounting for energy intake slightly increased the predictive ability of GL, which is potentially important when examining disease risk in more diverse populations with wider variations in energy requirements

Early diet quality in a longitudinal study of Australian children: associations with nutrition and body mass index later in childhood and adolescence

Obesity has origins extending to antenatal and early postnatal periods; however, the relationship between early postnatal diet and subsequent obesity is not well defined. The aims of this study were to determine whether early childhood dietary quality was associated with (a) infant and adolescent nutrition and (b) body mass index (BMI) in childhood and adolescence. The degree to which early nutrition and growth factors determine BMI throughout childhood and adolescence was also explored. This research was conducted using the Raine Study, a longitudinal survey of Australian children assessed from mid-gestation to 17 years of age. A dietary quality index, the Raine Eating Assessment in Toddler score, was assigned to 2562 participants to assess early nutrition. Linear regression determined that breastfeeding was associated with dietary quality at 1–3 years. Dietary elements at 14 years of age were related to earlier dietary quality. There were no consistent associations between early diet and BMI at 3, 5, 8, 10, 14 or 17 years. In contrast, birth weight and infant weight gain were significantly associated with BMI at these ages. This study suggests that early dietary patterns are associated with aspects of diet in adolescence, likely reflecting the influence of maternal reporting. Birth weight and early growth appear to be more important determinants of adolescent BMI than early diet and nutrition. While optimizing early diet by maternal nutritional education has potential to influence later nutrition, interventions focussing on early weight gain may have a greater impact on the obesity epidemic
