Two-way Interaction (two-way + interaction)
Selected AbstractsTwo-way interactions between ocean biota and climate mediated by biogeochemical cyclesISRAEL JOURNAL OF CHEMISTRY, Issue 1 2002Hezi Gildor Some of the two-way interactions between ocean biota and climate are mediated by biogeochemical cycles that link the different components of the climate system. As suggested by proxy records extracted from ice and ocean cores, by recent measurements, and by numerical models, such two-way interactions were likely major players in past climate variability on glacial,interglacial timescales, and may act to amplify or moderate an anthropogenically induced climate change in the near future. At present, our lack of understanding of these interactions hampers our ability to anticipate the consequences of possible anthropogenic climate change. In this article, we highlight some of the possible feedbacks between ocean biota and climate, reviewing some key biogeochemical processes and discussing mechanisms of two-way interactions. We also outline the need and strategies for continuing research aimed at advancing our understanding of these feedbacks and discuss their significance. [source] When being disadvantaged grows into vengeance: The effects of asymmetry of interest and social rejection in social dilemmasEUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 4 2009Jeroen Stouten In public good dilemmas, group members often differ in the extent to which they benefit from provision of the public good (asymmetry of interest). In the current paper, we argue that people may readily accept such financial differences in interest when their social needs are met by being accepted by the others. When people are socially rejected, however, members having a low rather than a high interest in the public good may display negative emotional and retributive reactions. This reasoning was supported by the findings of a first experimental study in which we manipulated people's interest in the public good and social rejection. These effects were replicated in a second experimental study and it was further shown that this two-way interaction between social rejection and interest in the public good was moderated by people's social value orientation. The negative reactions to low interest (vs. high interest) in the public good when being socially rejected were especially prominent among group members with a proself orientation. Taken together, the current studies illustrate the importance of studying how financial and social needs interact to determine emotional and retributive actions in social dilemmas.

[source] Effects of increased flow in the main stem of the River Rhine on the invertebrate communities of its tributariesFRESHWATER BIOLOGY, Issue 1 2005Melanie C. Beckmann Summary 1. We hypothesised that increased flow in the main stem of the River Rhine would influence the invertebrate communities of its tributaries and therefore investigated the invertebrate fauna of six tributaries over 2 years. 2. We collected quantitative invertebrate samples at three sites in each tributary: in the tributary mouth (influenced by Rhine water whenever flow in the Rhine exceeded mean annual level), in the zone reached by average floods (return period 1.5 years) in the Rhine (average flood level sites), and immediately upstream of the range of extreme Rhine floods (reference sites). Samples were taken in spring, summer and autumn of each year, at different flow levels of the Rhine. We also compared substratum composition at the three sites. 3. Tributary mouth sites had the finest substratum, the lowest total invertebrate density and the lowest taxon richness. At average flood level and reference sites, these three parameters were similar. 4. Taxa known to prefer larger rivers were mostly confined to the tributary mouth sites, and species preferring upland streams dominated at the average flood level and reference sites. 5. Multivariate analyses confirmed the influence of the Rhine on the tributary mouth sites. Invasive invertebrate species, which usually appear only in the Rhine itself, were found at the tributary mouth sites but not further up in the tributaries. 6. Our study shows that increased flow in the main stem of the Rhine influenced substratum composition and invertebrate communities at the tributary mouth sites. These results imply that the relationship between the main stem of a river and its tributaries is not one-way (from tributary to main stem), but rather a two-way interaction. [source] EVALUATION OF LENTIL TEXTURE MEASUREMENTS BY COMPRESSION TESTINGJOURNAL OF TEXTURE STUDIES, Issue 4 2000S. D. ARNTFIELD ABSTRACT The variability in texture for lentils of different size, from different locations and cooked for varying lengths of time was examined in relation to the sample size and the extent to which the sample was compressed during testing. The force to compress the lentils was found to be dependent on all variables examined and also demonstrated significant interactions between these variables. The coefficient of variability was dependent on the size of the lentil, a two-way interaction between sample size and compression and a three-way interaction between location, cooking time and sample size. Regardless of lentil size, location where the lentil was grown and the cooking time used, the variability in the texture readings was lowest when the larger sample size and maximum compression force were used. [source] Nutrigenomics,new approaches for human nutrition researchJOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 8 2006Helen M Roche Abstract Food intake and nutrient exposure are key environmental factors involved in the pathogenesis and progression of the common polygenic, diet-related diseases. An individual's phenotype represents a complex interaction between the human genome and environmental factors during an individual's lifetime. This review explores the concept that there is a dynamic, two-way interaction between nutrition and the human genome which determines gene expression, the metabolic response and an individual's health status. It addresses the relevance of new high-throughput genomic, transcriptomic, proteomic and metabolomic technologies within human nutrition research. Common, polygenic, diet-related diseases (CVD, obesity, T2DM, etc.) reflect multiple genetic variants interacting with numerous environmental factors, each combination making a relatively small contribution to overall cellular homeostasis, whole body metabolism and health. This review highlights the value of a nutrigenomics-based systems biology approach to understanding human nutrition and identifying new biomarkers of nutrition and health. The challenge will be to develop and apply robust nutritional genomics research initiatives that are sensitive enough to take account of both human genetic heterogeneity and diverse nutrient exposure. If nutrigenomic approaches enhance our understanding of human nutrition at the molecular level, then it may be possible to apply a more targeted and effective personalized nutrition approach to attenuate the effect of risk factors associated with diet-related diseases. Indeed it could be proposed that a personalized nutrition approach may assist in improving the effectiveness of dietary guidelines/recommendations in general.

However, this tendency for two-way positive interaction appears to be only a relatively recent phenomenon. The tendency for realizing the two-way interaction is not limited to the top-scoring firms in terms of both financial and environmental performance. On the contrary, this is also a trend that can be observed fairly generally. Obviously, when we consider only scores of those companies that published the relevant information in their environmental reports, and conduct the statistical causality test with such information as additional input to the pooled time-series and cross-section data of financial performance, the results become more strongly significant. From the recent experience of environmental policies in Japan, we infer that information-based environmental policy measures are effective to encourage the ongoing transition toward a more sustainable market economy.

Peluchette This study examined employee preferences for different styles of workplace attire and how wearing various styles of clothing affected their self-perceptions. Respondents felt most authoritative, trustworthy, and competent when wearing formal business attire but friendliest when wearing casual or business casual attire. Significant two-way interactions were found between dress preference and mode of dress worn on self-perceptions of productivity, trustworthiness, creativity, and friendliness. Suggestions for future research and implications for HRD professionals are proposed. [source] Symbolic Attributes and Organizational Attractiveness: The moderating effects of applicant personalityINTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 1 2009Bert Schreurs The present study examined the moderating influence of the Big Five personality factors in the relationship between five symbolic, trait-based inferences about organizations (Sincerity, Excitement, Competence, Prestige, and Ruggedness) and organizational attractiveness. Drawing on the similarity-attraction paradigm, six hypotheses were formulated, stating that the relationship between trait-based inferences and organizational attractiveness would be stronger for persons who perceive the organization as similar to them. Results of moderated regression analyses on data from a sample of 245 prospective applicants for the Belgian military revealed two significant two-way interactions, showing that Sincerity was positively related to organizational attractiveness only for individuals high on Conscientiousness, and that the relationship between Excitement and organizational attractiveness is more positive for individuals high on Openness to Experience. Practical implications, strengths and limitations, as well as directions for further research are presented.

[source] Postnatal testing for diabetes in Australian women following gestational diabetes mellitusAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 5 2009Melinda K. MORRISON Background:, Postnatal blood glucose testing is recommended for reclassification of glucose tolerance following a pregnancy affected by gestational diabetes mellitus (GDM); however, there are limited data on the postnatal follow-up sought by Australian women. Aims:, To describe postnatal diabetes testing patterns in Australian women following a pregnancy affected by GDM and identify factors associated with return for follow-up testing in accordance with the Australasian Diabetes in Pregnancy Society (ADIPS) guidelines. Methods:, A cross-sectional self-administered survey of 1372 women diagnosed with GDM between 2003 and 2005, sampled from the National Diabetes Services Scheme database. Results:, Postnatal diabetes testing was reported by 73.2% of survey respondents with 27.4% returning for an oral glucose test tolerance at six to eight weeks post-GDM pregnancy. Using logistic regression analysis, factors associated with appropriate postnatal testing were receiving individualised risk reduction advice (odds ratio (OR) 1.41 (1.08,1.84)) or written information (OR 1.35 (1.03,1.76)) and in two-way interactions, being under the care of an endocrinologist and not tertiary educated (OR 2.09 (1.49,2.93)) as well as seeing an obstetrician and diabetes educator during pregnancy (OR 1.72 (1.19,2.48)). Every five years increase in age reduced the likelihood of a woman returning for testing by 17%. Conclusions:, Specialist diabetes care in non-tertiary educated women, or a team approach to management with diabetes education and obstetric care may act to reinforce the need for postnatal diabetes testing in accordance with the ADIPS guidelines. Individualised follow up from a health professional and provision of written information following a GDM pregnancy may also encourage return for postnatal testing in this high-risk group. [source] Bayesian Logistic Injury Severity Score: A Method for Predicting Mortality Using International Classification of Disease-9 CodesACADEMIC EMERGENCY MEDICINE, Issue 5 2008Randall S. Burd MD Abstract Objectives:, Owing to the large number of injury International Classification of Disease-9 revision (ICD-9) codes, it is not feasible to use standard regression methods to estimate the independent risk of death for each injury code. Bayesian logistic regression is a method that can select among a large numbers of predictors without loss of model performance. The purpose of this study was to develop a model for predicting in-hospital trauma deaths based on this method and to compare its performance with the ICD-9,based Injury Severity Score (ICISS). Methods:, The authors used Bayesian logistic regression to train and test models for predicting mortality based on injury ICD-9 codes (2,210 codes) and injury codes with two-way interactions (243,037 codes and interactions) using data from the National Trauma Data Bank (NTDB). They evaluated discrimination using area under the receiver operating curve (AUC) and calibration with the Hosmer-Lemeshow (HL) h-statistic. The authors compared performance of these models with one developed using ICISS. Results:, The discrimination of a model developed using individual ICD-9 codes was similar to that of a model developed using individual codes and their interactions (AUC = 0.888 vs. 0.892). Inclusion of injury interactions, however, improved model calibration (HL h-statistic = 2,737 vs. 1,347). A model based on ICISS had similar discrimination (AUC = .855) but showed worse calibration (HL h-statistic = 45,237) than those based on regression. Conclusions:, A model that incorporates injury interactions had better predictive performance than one based only on individual injuries. A regression approach to predicting injury mortality based on injury ICD-9 codes yields models with better predictive performance than ICISS. [source] | ||||||||||||||||
