AbstractObjectiveTo assess tracking of energy and nutrient intakes between adolescence and young adulthood.DesignLongitudinal study of a random sample of adolescents (aged 15 years at baseline). The extent of tracking of dietary intakes (assessed by diet history) was investigated using weighted kappa statistics (κ).SettingNorthern Ireland population survey.SubjectsAdolescents who participated in the Young Hearts Project, Northern Ireland at age 15 years, and subsequently at young adulthood aged between 20 and 25 years (n = 245 males,n = 231 females).ResultsDespite overall increases in height and weight (bothP < 0.001), increases in body mass index in males (P < 0.001) and body fatness in females (P < 0.001), median reported intakes of energy (kJ kg− 1 day− 1), carbohydrate (g day− 1) and fat (g day− 1) decreased (allP < 0.001) over time. Expressed as nutrient densities (per MJ), diets at young adulthood were overall richer in thiamin, vitamin B6, total folate (allP < 0.001), vitamin C (P < 0.01) and vitamin D (P < 0.05). Whereas the nutrient density of the males' diets decreased over time for calcium (P < 0.05) and vitamin A (P < 0.001), iron and riboflavin densities increased in the females' diet (P < 0.001). Tracking of energy (MJ day− 1) and nutrient intakes (expressed per MJ day− 1) at the individual level was only poor to fair (all κ < 0.25), indicating substantial drift of subjects between the low, medium and high classes of intake with increasing age.ConclusionsThese data suggest that individual dietary patterns exhibited at 15 years of age are unlikely to be predictive of dietary intakes at young adulthood.

Energy And Nutrient Intake

This study evaluated the tracking of energy and nutrient intakes, assessed by diet history, in a random sample of adolescents (boys n 225, girls n 230) at baseline (age 12 years), and subsequently at age 15 years. Median energy (MJ/d) and macronutrient (g/d) intakes increased significantly (all P<0·001) with increasing age in the boys. The girls' reported energy intake (MJ/d) remained stable over time, despite significant increases in BMI, weight and % body fat. Age-related changes in the girls' macronutrient intakes were inconsistent. When expressed in terms of nutrient density, the diets of both sexes became significantly richer, over time, in total folate (both sexes, P<0·01), but poorer in Ca (boys P<0·01, girls P<0·001) and riboflavin (both sexes P<0·001). Vitamin B6 (P<0·001) and Fe (P<0·05) densities increased in the boys, while the thiamin density of the girls' diets decreased (P<0·001). Tracking, defined as maintenance of rank over time, was summarised using weighted kappa statistics (κ). There were some significant changes in intakes at the group level; however, tracking of energy and nutrients in both sexes was only poor to fair (κ<0·40), indicating substantial drift of individuals between classes of intake over time. Particularly poor tracking was evident for % energy from sugars (κ 0·09) and total fat (κ 0·09) in the girls' diets. In conclusion, the poor to fair tracking observed in this cohort suggests that individual dietary patterns exhibited at 12 years of age are unlikely to be predictive of energy and nutrient intake at age 15 years.

Personal concerns about climate change and the environment are a powerful motivator of sustainable behavior. People’s level of concern varies as a function of a variety of social and individual factors. Using data from 58,748 participants from a nationally representative German sample, we tested preregistered hypotheses about factors that impact concerns about the environment over time. We found that environmental concerns increased modestly from 2009-2017 in the German population. However, individuals in middle adulthood tended to be more concerned and showed more consistent increases in concern over time than younger or older people. Consistent with previous research, Big Five personality traits were correlated with environmental concerns. We present novel evidence that increases in concern were related to increases in the personality traits neuroticism and openness to experience. Indeed, changes in openness explained roughly 50% of the variance in changes in environmental concerns. These findings highlight the importance of understanding the individual level factors associated with changes in environmental concerns over time, towards the promotion of more sustainable behavior at the individual level.

Abstract Our objective is to study Canada’s patenting activity over time in aggregate terms by destination country, by assignee and destination country, and by diversification by country of destination. We collect bibliographic patent data from the Canadian Intellectual Property Office and the United States Patent and Trademark Office. We identify 19,957 matched Canada–US patents, 34,032 Canada-only patents, and 43,656 US-only patents from 1980 to 2014. Telecommunications dominates in terms of International Patent Classification technologies for US-only and Canada–US patents. At the firm level, the greatest number of matched Canada–US patents were granted in the field of telecommunications, at the university level in pharmaceuticals, at the government level in control and instrumentation technology, and at the individual level in civil engineering. We use entropy to quantify technological diversification and find that diversification indices decline over time for Canada and the USA; however, all US indices decline at a faster rate.

Abstract Objectives Individuals often manage chronic conditions in middle and later life that may diminish well-being. Little is known, however, about discordant conditions (i.e., two or more conditions with competing self-management requirements) among older couples and their links to depressive symptoms. We considered discordant conditions at both the individual level and the couple level (i.e., between spouses), along with their long-term implications for depressive symptoms. Methods The U.S. sample included 1,116 middle-aged and older couples drawn from five waves (2006–2014) of the Health and Retirement Study. Longitudinal actor-partner interdependence models evaluated whether individual-level and couple-level discordant chronic health conditions were concurrently linked to depressive symptoms, and whether these associations became stronger over time. Models controlled for age, minority status, education, prior wave depressive symptoms, and each partner’s baseline report of negative marital quality and number of chronic conditions in each wave. Results Wives and husbands reported significantly greater depressive symptoms when they had individual-level discordant conditions about 2 years after baseline, and these links intensified over time. Beyond this association, husbands had significantly greater depressive symptoms when there were couple-level discordant conditions. Discussion Individual-level and couple-level discordant conditions may have lasting implications for depressive symptoms during midlife and older adulthood.

This paper examines Howard's (1963) typology dividing decision making into extensive problem solving (ESP), limited problem solving (LSP), and routinized response behavior (RRB). Specifically, the amount of information accessed in a longitudinal experiment is studied. Information acquisition is modeled stochastically at the individual level, and the existence of two segments (LSP and RRB) is tested in a nested-model framework.

This paper introduces a connectionist Agent-Based Model (cABM) that incorporates detailed, micro-level understanding of social influence processes derived from laboratory studies and that aims to contextualize these processes in such a way that it becomes possible to model multidirectional, dynamic influences in extended social networks. At the micro-level, agent processes are simulated by recurrent auto-associative networks, an architecture that has a proven ability to simulate a variety of individual psychological and memory processes [D. Van Rooy, F. Van Overwalle, T. Vanhoomissen, C. Labiouse and R. French, Psychol. Rev. 110, 536 (2003)]. At the macro-level, these individual networks are combined into a "community of networks" so that they can exchange their individual information with each other by transmitting information on the same concepts from one net to another. This essentially creates a network structure that reflects a social system in which (a collection of) nodes represent individual agents and the links between agents the mutual social influences that connect them [B. Hazlehurst, and E. Hutchins, Lang. Cogn. Process. 13, 373 (1998)]. The network structure itself is dynamic and shaped by the interactions between the individual agents through simple processes of social adaptation. Through simulations, the cABM generates a number of novel predictions that broadly address three main issues: (1) the consequences of the interaction between multiple sources and targets of social influence (2) the dynamic development of social influence over time and (3) collective and individual opinion trajectories over time. Some of the predictions regarding individual level processes have been tested and confirmed in laboratory experiments. In a extensive research program, data is currently being collected from real groups that will allow validating the predictions of cABM regarding aggregate outcomes.

AbstractObjectiveThe present study evaluates the reliability and validity of an FFQ designed for use with adolescents in urban Vietnam.DesignA cohort study was conducted between December 2003 and June 2004. The FFQ was administered three times over a 6-month period (FFQ 1–3) and nutrient intakes were compared to those obtained from four 24 h recalls collected over the same period (24 h recalls 1–4) using crude, energy-adjusted and de-attenuated correlation coefficients. The level of agreement between the two measurements was also evaluated with Bland–Altman analysis. The percentage of nutrient intakes classified within one quintile, as well as quadratic-weighted kappa statistics, were calculated.SettingHo Chi Minh City, Vietnam.SubjectsA total of 180 students were recruited in three junior high schools.ResultsCoefficients ranged from 0·22 for retinol to 0·78 for fibre for short-term reliability, and from 0·30 for retinol to 0·81 for zinc for long-term reliability. Coefficients for nutrient intakes between the mean of the three FFQ and mean of four 24 h recalls were mostly around 0·40, but higher for energy-adjusted nutrients. After allowing for within-person variation, the mean coefficient was 0·52 for macronutrients and 0·46 for micronutrients. There were a relatively high proportion of nutrient intakes classified within one quintile and a small number grossly misclassified. Kappa values shows ‘fair’ to ‘good’ agreement for all food/nutrient categories, while the Bland–Altman plots indicated that the FFQ is accurate in assessing nutrient intake at a group level.ConclusionsThis newly developed FFQ is a valid tool for measuring nutrient intake in adolescents in urban Vietnam.

AbstractStudies using data from the early 1990s suggested that while the progressive Social Security benefit formula succeeded in redistributing benefits from individuals with high earnings to individuals with low earnings, it was much less successful in redistributing benefits from households with high earnings to households with low earnings. Wives often earned much less than their husbands. As a result, much of the redistribution at the individual level was effectively from high earning husbands to their own lower earning wives. In addition, spouse and survivor benefits accrue disproportionately to women from high income households. Both factors mitigate redistribution at the household level. It has been argued that with the increase in the labor force participation and earnings of women, Social Security now should do a better job of redistributing benefits at the household level. To be sure, when we compare outcomes for a cohort with a household member age 51 to 56 in 1992 with those from a cohort born twelve years later, redistribution at the household level has increased over time. Nevertheless, as of 2004 there still is substantially less redistribution of benefits from high to low earning households than from high to low earning individuals.

Over Time

Over the years, employee opinion surveys have evolved in their use and how they are conducted. A major advancement has been the use of linkage analyses, whereby employee attitudes at a unit level are statistically related to other important organizational outcomes. A more recent development has been linkage analyses at the individual level and over time. In order to carry out these types of analyses, “identified surveys” must be used—surveys that retain identifying information on each survey respondent in order to link with other individual-level variables over time. The purpose of this article is to open up a discussion on identified surveys, describe under what circumstances they may be uniquely beneficial, and highlight potential concerns with them. We close with proposed guidelines for professional practice and recommend that our profession have a point of view on identified surveys for ourselves and to advise others.

We consider cultural differences in how moral concerns can shape responses to intergroup- level authority decisions – that is, decisions that allocate outcomes between different groups. We hypothesised that at the individual level, moral foundations may predict how people respond to authority decisions that either favour or disfavour their group, and that this relationship would be different depending on culture. The extent to which those values lead to the expected responses to authority decisions was investigated in two samples of students in Northern Ireland and Malaysia (N = 318). Participants read about two government decisions to distribute prestigious internships between their own and another university (in favouring or disfavouring ratios) and responded to scales measuring their decision acceptance and perceptions of fairness. We found that moral concern for authority - but not loyalty or fairness - predicted how students responded to authority decisions. However, cultural context moderated this effect. For Malaysian students, higher moral concern for authority predicted less preference for the pro-ingroup authority decision, whereas for the Northern Irish sample, the reverse was true. Thus, we demonstrate that the understanding of values is culture-specific and can translate to the opposing behaviours, depending on the context.
