Previous models of parental educational investments focus on the composition of the sibship (number, gender, ordering, and spacing) and on the social and institutional context in which investment decisions are made. Social-institutional models predict that parents in Japan are likely to underinvest in girls because of their transient status in the…

Sociologists have extensively documented the ways that parent resources predict children's achievement. However, less is known about whether and how children's academic performance shapes parental investment behaviors. I use data from the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K) and longitudinal fixed effects models to examine how changes in teacher assessments are related to changes in the conferral of various parent resources. Overall, I find that the relationship between achievement and investment varies based on the directionality in children's achievement and the type of resource at hand. Children whose performance improves receive a broad range of enrichment resources, while declines in performance are met with corrective educational resources. Results are largely consistent whether language or math assessments are used to predict investment, and also among children whose achievement does not change over time. I discuss these patterns, along with implications for the use of parent resources in education and family research. Copyright © 2014 Elsevier Inc. All rights reserved.

I investigated how the interrelationship between parental investment and sexual immune dimorphism shape the evolution of parental care strategies within the cichlids and syngnathids. To understand why parental investment is displayed in such diversity in the animal kingdom, I assessed evolutionary and provisioning costs of parental investment in male pregnancy, biparental and maternal mouthbrooding. Additionally, to address the importance of parental investment, I tested for maternal effects ...

Empirical evidence suggests that parental preferences may be important in determining investment allocations among their children. However, there is mixed or no evidence on a number of important related questions. Do parents invest more in better-endowed children, thus reinforcing differentials among their children? Or do they invest more in less-endowed children to compensate for their smaller endowments and reduce inequalities among their children? Does higher maternal education affect the preferences underlying parental decisions in investing among their children? What difference might such intrafamilial investments among children make? And what is the nature of these considerations in the very different context of developing countries? This paper gives new empirical evidence related to these questions. We examine how parental investments affecting child education and health respond to initial endowment differences between twins within families, as represented by birth weight differences, and how parental preference tradeoffs and therefore parental investment strategies vary between families with different maternal education. Using the separable earnings-transfers model (Behrman et al., 1982), we first illustrate that preference differences may make a considerable difference in the ratios of health and learning differentials between siblings - up to 30% in the simulations that we provide. Using a sample of 2000 twins, collected in the 2012 wave of the Early Childhood Longitudinal Survey for Chile, we find that preferences are not at the extreme of pure compensatory investments to offset endowment inequalities among siblings nor at the extreme of pure reinforcement to favor the better-endowed child with no concern about inequality. Instead, they are neutral, so that parental investments do not change the inequality among children due to endowment differentials. We also find that there are not significant preference differences between families with low- and high
Although great effort has been spent on studying the effects of parenting on child development, much less research has focused on factors that predict individual differences in parental investment. In this dissertation, an evolutionary psychological perspective was used to identify characteristics

We propose a household production function approach to human development in which the role of parenting style in child rearing is explicitly considered. Specifically, we model parenting style as an investment in human development that depends not only on inputs of time and market goods, but also on attention, i.e. cognitive effort. Socioeconomic disadvantage is linked to parenting style and human development through the constraints that it places on cognitive capacity. Our model finds empiric...

Male and female parents often provide different type and amount of care to their offspring. Three major drivers have been proposed to explain parental sex roles: (1) differential gametic investment by males and females that precipitates into sex difference in care, (2) different intensity of sexual selection acting on males and females, and (3) biased social environment that facilitates the more common sex to provide more care. Here, we provide the most comprehensive assessment of these hypotheses using detailed parental care data from 792 bird species covering 126 families. We found no evidence for the gametic investment hypothesis: neither gamete sizes nor gamete production by males relative to females was related to sex difference in parental care. However, sexual selection correlated with parental sex roles, because the male share in care relative to female decreased with both extra-pair paternity and frequency of male polygamy. Parental sex roles were also related to social environment, because male parental care increased with male-biased adult sex ratios (ASRs). Taken together, our results are consistent with recent theories suggesting that gametic investment is not tied to parental sex roles, and highlight the importance of both sexual selection and ASR in influencing parental sex roles. © 2015 The Author(s).

In the parental investment conflict each of the sexes decides how much to invest in its brood, where its decision influences both sexes' fitness. In nature, each species is usually characterized by a common parental care pattern, male-only care, female-only care or biparental care. A possible way for understanding the factors that have led each species to adopt its unique parental care pattern is to analyse a male's and a female's decision process using a game-theoretical model. This paper suggests a two-stage game-theoretical model with two types of players, male and female. During the game each parent makes three decisions. The interval between the beginning of the game, i.e. after mating and having offspring, and the moment a parent starts to care for them is a random variable. Thus, in the first stage a parent chooses the cumulative probability distribution of this interval, and its amount of parental care. In the second stage the other parent chooses its probability for cooperation. It is assumed that as long as parental care is not provided the offspring are at risk, and that parental caring accrues a different cost for each sex. We compute the Evolutionary Stable Strategies (ESS) under payoff-relevant asymmetry, and show that uniparental and biparental care are possible ESS. We also characterize cases where the sex having the lower cost "forces" the sex having the higher cost to care and vice versa.

Parental care increases parental fitness through improved offspring condition and survival but comes at a cost for the caretaker(s). To increase life-time fitness, caring parents are, therefore, expected to adjust their reproductive investment to current environmental conditions and parental capacities. The latter is thought to be signaled via ornamental traits of the bearer. We here investigated whether pre- and/or posthatching investment of blue tit (Cyanistes caeruleus) parents was related to ornamental plumage traits (UV crown coloration and carotenoid-based plumage coloration) expressed by either the individual itself (i.e. "good parent hypothesis") or its partner (i.e. "differential allocation hypothesis"). Our results show that neither prehatching (that is clutch size and offspring begging intensity) nor posthatching parental investment (provisioning rate, offspring body condition at fledging) was related to an individual's UV crown coloration or to that of its partner. Similar observations were made for carotenoid-based plumage coloration, except for a consistent positive relationship between offspring begging intensity and maternal carotenoid-based plumage coloration. This sex-specific pattern likely reflects a maternal effect mediated via maternally derived egg substances, given that the relationship persisted when offspring were cross-fostered. This suggests that females adjust their offspring's phenotype toward own phenotype, which may facilitate in particular mother-offspring co-adaptation. Overall, our results contribute to the current state of evidence that structural or pigment-based plumage coloration of blue tits are inconsistently correlated with central life-history traits.
Full Text Available Parents do not invest their resources in their children equally. Three factors which elicit differential parental investment are the parent's reproductive value, the child's reproductive value (RV, and the impact of the investment on the child (II. As the child matures, his RV increases while the II may decrease. This raises a question regarding the favored strategy of investment by child age. It was hypothesized that different categories of parental investment generate different age-based strategies. Emotional investment, such as maternal worrying for the child's health, was hypothesized to increase with the child's age, while direct care was hypothesized to decrease with the child's age. Both categories were hypothesized to increase with the mother's age at childbirth. 137 Israeli mothers of children with chronic neurological conditions reported levels of worrying for their child and levels of change in direct care. Maternal worrying about the child's health was positively associated with the child's age at diagnosis and the severity of his illness, and negatively associated with the time from diagnosis. An increase in direct care was positively associated with maternal age at childbirth and illness severity, and negatively associated with the time from diagnosis, and the duration of the marriage. Contrary to the hypothesis, the child's age had no effect on changes in direct care. It appears that in mothers of children with adverse neurological conditions, child and maternal age effect parental investment differently. While the child's age is related to maternal worrying about his health, the mother's age at childbirth is related to changes in direct care.

Significant relationships have been demonstrated between parental personality and parenting toward individual children, but there is little research exploring the relationship between parental personality and differential parenting (DP). The present study examined the relationship between the Big Five personality dimensions and differential positivity and negativity in parenting (observed and self-report measures). The analyses are based on a sample of 867 children nested within 381 families. Using multilevel modeling and controlling for child age, gender, birth order, behavior, and family socioeconomic status analyses revealed that maternal and paternal agreeableness were inversely related to reports of differential positivity. Agreeableness predicted observed differential negativity, and the relationship was curvilinear (at both high and low levels of agreeableness, differential negativity was higher). Finally, mothers with the most openness to experience exhibited the highest levels of reported differential negativity. The findings suggest that parental personality is a modest yet important influence to consider when conceptualizing the sources of DP. PsycINFO Database Record (c) 2012 APA, all rights reserved.
Full Text Available Parental differential treatment is an important feature of non-shared family environment which contributes to the development of behavioural differences between siblings growing up in the same family. To investigate the frequency, direction, and patterns of parental differential treatment of siblings in Slovene families, mothers and fathers of 93 sibling-pairs in early/middle childhood provided self-reports in a two-wave longitudinal study. Most of the parents reported on low levels of differential treatment, predominantly expressing somewhat more affection and control towards the older than towards the younger sibling. Over a one-year time period, the average frequency of parental differential treatment did not change significantly, whereas the stability was estimated as moderate for maternal and low for paternal assessments. Maternal and paternal self-ratings were moderately correlated. However, the mothers reported on somewhat higher levels of differential control and (only in wave 1 affection than the fathers. Nearly half of the families were characterized by a congruent pattern of parental differential treatment indicating that both parents showed more affection and control towards the older of the two siblings. A complementary family pattern reflecting an opposite direction of maternal and paternal differential treatment emerged in approximately a quarter of the participating families.

The genetic conflict between parents and their offspring is a cornerstone of kin selection theory and the gene-centred view of evolution, but whether it actually occurs in natural systems remains an open question. Conflict operates only if parenting is driven by genetic trade-offs between offspring performance and the parent's ability to raise additional offspring, and its expression critically depends on the shape of these trade-offs. Here we investigate the occurrence and nature of genetic conflict in an insect with maternal care, the earwig Forficula auricularia. Specifically, we test for a direct response to experimental selection on female future reproduction and correlated responses in current offspring survival, developmental rate and growth. The results demonstrate genetic trade-offs that differ in shape before and after hatching. Our study not only provides direct evidence for parent-offspring conflict but also highlights that conflict is not inevitable and critically depends on the genetic trade-offs shaping parental investment.

Males typically have greater variance in reproductive success than females, so mothers should benefit by producing sons under favorable conditions. Being paired with a better-than-average mate is one such favorable circumstance. High-quality fathers can improve conditions for their offspring by providing good genes, good resources, or both, so females paired to such males should invest preferentially in sons. Ornamentation has been linked to male quality in many birds and, in support of differential allocation theory, females of several avian species invest more in entire broods when paired to attractive mates. Additionally, the females of some bird species apparently manipulate the primary sex-ratio of their broods in relation to the attractiveness of their mates. However, empirical support for a link between mate ornamentation and preferential feeding of sons (another form of biased investment) is lacking. We tested for correlations between sex-biased parental investment and mate plumage colour in the eastern bluebird (Sialia sialis), a species in which juveniles have sexually dichromatic UV-blue plumage. We found that the proportion of maternal feeding attempts to fledgling sons (versus fledgling daughters) was positively correlated with structurally coloured plumage ornamentation of fathers. Additionally, paternal feeding attempts to sons were correlated with plumage ornamentation of mothers and increased in fathers exhibiting breast plumage characteristics typical of older males. These results provide further support for the idea that parental strategies are influenced by mate attractiveness and provide the first evidence that mate ornamentation can influence parental behavior even after offspring have left the nest.

Full Text Available Hagen's Defection Hypothesis (2002 predicts that a mother's age and the quality of her offspring are critical factors in determining her investment in her newborn. We tested this hypothesis using hamster races in which 113 college student participants received a hamster (“offspring” and 10 poker chips (“resources” to “invest” into the hamster based on information about the quality of the hamster and about the possibility of future races. Subjects invested the most in low quality offspring when they expected to run only one race and the least in low quality offspring when they expected more racing opportunities in the future. Offspring quality affected investment differently depending on the presence or absence of future investment opportunities and the sex of the subject. Overall, the results supported Hagen's model of parental investment and also suggest that parental investment may be explained by conscious as well as unconscious decision-making.

The differential allocation hypothesis predicts that reproductive investment will be influenced by mate attractiveness, given a cost to reproduction and a tradeoff between current and future reproduction. We tested the differential allocation hypothesis in the swordtail fish Xiphophorus multilineatus, where males have genetically influenced (patroclinous inheritance) alternative mating tactics (ARTs) maintained by a tradeoff between being more attractive to females (mature later as larger courting males) and a higher probability of reaching sexual maturity (mature earlier as smaller sneaker males). Males in X. multilineatus do not provide parental care or other resources to the offspring. Allelic variation and copy number of the Mc4R gene on the Y-chromosome influences the size differences between males, however there is no variation in this gene on the X-chromosome. Therefore, to determine if mothers invested more in offspring of the larger courter males, we examined age to sexual maturity for daughters. We confirmed a tradeoff between number of offspring and female offspring's age to sexual maturity, corroborating that there is a cost to reproduction. In addition, the ART of their fathers significantly influenced the age at which daughters reached sexual maturity, suggesting increased maternal investment to daughters of courter males. The differential allocation we detected was influenced by how long the wild-caught mother had been in the laboratory, as there was a brood order by father genotype (ART) interaction. These results suggest that females can adjust their reproductive investment strategy, and that differential allocation is context specific. We hypothesize that one of two aspects of laboratory conditions produced this shift: increased female condition due to higher quality diet, and/or assessment of future mating opportunities due to isolation from males.

Reproduction is the most fundamental of evolutionary behaviors, yet human parents face especially complex tradeoffs when deciding how many children to have and how much to invest in each of them. This chapter reviews parental investment theory, including both the key concepts and some important questions to which they have been applied in humans. Written primarily from the perspective of human behavioral ecology, this chapter also discusses how evolutionary social scientists have approached cross-cultural variation in parenting behavior. The chapter begins with an overview of life history theory and the concept of reproductive tradeoffs, focusing especially on the tradeoffs between current vs. future reproduction and quantity vs. quality of offspring. Discussing the critical question of who invests in offspring, I next compare motivations for investment between mothers and fathers, and explore the roles of many types of kin in investment, while considering whether humans can be viewed as cooperative breeders. I then explore the role of parent-offspring conflict and sibling conflict in parental investment and inheritance systems, followed by an exploration of sex biases in investment, including the Trivers-Willard effect local resource competition, and local resource enhancement. In conclusion, I argue that parental investment has been one of the most active areas of enquiry among evolutionary researchers over the last twenty years, and is likely to remain one of the mainstays of the field during the coming decades.

The present study examined the mediating role of perceived parental warmth and support in predicting Chinese Malaysian adolescents' filial behaviors from their age, perceived parental investments, and positive filial emotions toward their parents. The effects of these predictors were examined separately for mothers and fathers. Participants included 122 Chinese adolescents (M = 13.14 years; SD = 2.22) in Malaysia. Adolescents' perceived parental investments, filial emotions, and warmth and support from each parent were positively, and age was negatively associated with their filial behaviors. No gender differences were found. Perceived maternal warmth and support significantly mediated the effect of age, perceived investments from, and filial emotions toward mothers on adolescents' filial behaviors, but perceived paternal warmth and support did not have a mediating role. The present study sheds light on the unique maternal versus paternal filial role, and important familial processes in Chinese-Malaysian children and adolescents from a cultural perspective.

This paper tests the Trivers-Willard hypothesis that high-status individuals will invest more in sons and low-status individuals will invest more in daughters using data from the 2000 to 2010 General Social Survey and the 1979 National Longitudinal Survey of Youth. We argue that the primary investment U.S. parents make in their children is in their children's education, and this investment is facilitated by a diverse market of educational choices at every educational level. We examine two measures of this investment: children's years of education and the highest degree attained. Results show that sons of high-status fathers receive more years of education and higher degrees than daughters, whereas daughters of low-status fathers receive more years of education and higher degrees than sons. Further analyses of possible mechanisms for these findings yield null results. We also find that males are more likely to have high-status fathers than females.
Full Text Available The theory of evolution inevitably directs our thoughts towards classical Darwinist concept of the natural selection - competition for survival of the fittest. However, Darwin was trying to explain that a process of evolution is much more than that. Actually survival without reproduction means genetical cul de sac (blind road. Looking from evolutional perspective, there is nothing more important than reproduction and parenthood. Therefore, by considering earlier evolutionary concepts Robert Trievers (Trievers, 1972 was among the first authors who described basic reproductive differences between sexes in his theory parents' investment. Sexual selection is in a very gist of Darwin's theory. Understanding differences between women and men in their parent's investment has facilitated a start of human reproduction psychology studies. Reproduction task could be divided into two phases: finding an appropriate partner and raising descendants till their maturity. Men invest more energy in a first phase, while women invest more in a second one. As parent's resources are limited, it is necessary that they invest wisely into their descendants, because if they don't survive and don't spawn invested resources were from evolution point of view - wasted. This paper will analyze some of these questions by considering parents' investment theory and earlier studies on the theory of evolution.

Parental care, while increasing parental fitness through offspring survival, also bears cost to the care-giving parent. Consequentially, trade offs between parental care and other vitally important traits, such as the immune system seem evident. In co-occurring phases of parental care and immunological challenges negative consequences through a resource allocation trade off on both the parental and the offspring conditions can be predicted. While the immune system reflects parental stress conditions, parental immunological investments also boost offspring survival via the transfer of immunological substances (trans-generational immune priming). We investigated this relationship in the mouthbrooding East African cichlid Astotatilapia burtoni. Prior to mating, females were exposed to an immunological activation, while others remained immunologically naïve. Correspondingly, the immunological status of females was either examined directly after reproduction or after mouthbrooding had ceased. Offspring from both groups were exposed to immunological challenges to assess the extent of trans-generational immune priming. As proxy for immune status, cellular immunological activity and gene expression were determined. Both reproducing and mouthbrooding females allocate their resources towards reproduction. While upon reproduction the innate immune system was impeded, mouthbrooding females showed an attenuation of inflammatory components. Juveniles from immune challenged mouthbrooding females showed downregulation of immune and life history candidate genes, implying a limitation of trans-generational plasticity when parents experience stress during the costly reproductive phase. Our results provide evidence that both parental investment via mouthbrooding and the rise of the immunological activity upon an immune challenge are costly traits. If applied simultaneously, not only mothers seem to be impacted in their performance, but also offspring are impeded in their ability to

Population growth in the next half-century is on pace to raise global carbon emissions by half. Carbon emissions are associated with fertility as a by-product of somatic and parental investment, which is predicted to involve time orientation/preference as a mediating psychological mechanism. Here, we draw upon life-history theory (LHT) to investigate associations between future orientation and fertility, and their impacts on carbon emissions. We argue ' K -strategy' life history (LH) in high-income countries has resulted in parental investment behaviours involving future orientation that, paradoxically, promote unsustainable carbon emissions, thereby lowering the Earth's K or carrying capacity. Increasing the rate of approach towards this capacity are ' r -strategy' LHs in low-income countries that promote population growth. We explore interactions between future orientation and development that might slow the rate of approach towards global K . Examination of 67 000 individuals across 75 countries suggests that future orientation interacts with the relationship between environmental risk and fertility and with development related parental investment, particularly investment in higher education, to slow population growth and mitigate per capita carbon emissions. Results emphasize that LHT will be an important tool in understanding the demographic and consumption patterns that drive anthropogenic climate change.

How to optimally allocate time, energy and investment in an effort to maximize one's reproductive success is a fundamental problem faced by all organisms. This effort is complicated when the production of each additional offspring dilutes the total resources available for parental investment. Although a quantity-quality trade-off between producing and investing in offspring has long been assumed in evolutionary biology, testing it directly in humans is difficult, partly owing to the long generation time of our species. Using data from an Icelandic genealogy (Íslendingabók) over two centuries, I address this issue and analyse the quantity-quality trade-off in humans. I demonstrate that the primary impact of parents on the fitness of their children is the result of resources and or investment, but not genes. This effect changes significantly across time, in response to environmental conditions. Overall, increasing reproduction has negative fitness consequences on offspring, such that each additional sibling reduces an individual's average lifespan and lifetime reproductive success. This analysis provides insights into the evolutionary conflict between producing and investing in children while also shedding light on some of the causes of the demographic transition.

Sexual selection in the form of sperm competition is a major explanation for small size of male gametes. Can sexual selection in polyandrous species with reversed sex roles also lead to reduced female gamete size? Comparative studies show that egg size in birds tends to decrease as a lineage evolves social polyandry. Here, a quantitative genetic model predicts that female scrambles over mates lead to evolution of reduced female gamete size. Increased female mating success drives the evolution of smaller eggs, which take less time to produce, until balanced by lowered offspring survival. Mean egg size is usually reduced and polyandry increased by increasing sex ratio (male bias) and maximum possible number of mates. Polyandry also increases with the asynchrony (variance) in female breeding start. Opportunity for sexual selection increases with the maximum number of mates but decreases with increasing sex ratio. It is well known that parental investment can affect sexual selection. The model suggests that the influence is mutual: owing to a coevolutionary feedback loop, sexual selection in females also shapes initial parental investment by reducing egg size. Feedback between sexual selection and parental investment may be common.

Sex-role evolution theory attempts to explain the origin and direction of male-female differences. A fundamental question is why anisogamy, the difference in gamete size that defines the sexes, has repeatedly led to large differences in subsequent parental care. Here we construct models to confirm predictions that individuals benefit less from caring when they face stronger sexual selection and/or lower certainty of parentage. However, we overturn the widely cited claim that a negative feedback between the operational sex ratio and the opportunity cost of care selects for egalitarian sex roles. We further argue that our model does not predict any effect of the adult sex ratio (ASR) that is independent of the source of ASR variation. Finally, to increase realism and unify earlier models, we allow for coevolution between parental investment and investment in sexually selected traits. Our model confirms that small initial differences in parental investment tend to increase due to positive evolutionary feedback, formally supporting long-standing, but unsubstantiated, verbal arguments.

Demonstrating the impact that parents have on the fitness of their children is a crucial step towards understanding how parental investment has affected human evolution. Parents not only transfer genes to their children, they also influence their environments. By analyzing reproductive patterns within and between different categories of close relatives, this study provides insight into the genetic and environmental effects that parents have on the fitness of their offspring. We use data spanning over two centuries from an exceptionally accurate Icelandic genealogy, Íslendingabók, to analyze the relationship between the fertility rates of close relatives. Also, using genetic data, we determine narrow sense heritability estimates ( h 2 ) to further explore the genetic impact on lifetime reproductive success. Finally, we construct four simulations to model the expected contribution of genes and resources on reproductive success. The relationship between the reproduction of all full sibling pairs was significant and positive across all birth decades ( r = 0.19) while the reproductive relationship between parents and offspring was often negative across many decades and undetectable overall ( r = 0.00) (Fig. 1 and Table 1). Meanwhile, genetic data among 8,456 pairs of full siblings revealed a narrow sense heritability estimate ( h 2 ) of 0.00 for lifetime reproductive success. A resources model (following the rule that resources are transmitted from parents to children, distributed equally among siblings, and are the only factor affecting reproductive success) revealed a similar trend: a negative relationship between parent and offspring reproduction ( r = - 0.35) but a positive relationship among full siblings ( r = 0.28). The relationship between parent and offspring lifetime reproductive success (LRS) and full sibling LRS was strongly and positively correlated across time ( r = 0.799, p investment has had an important impact on fitness.

Studied here were the links between sibling differences in trajectories of change in the qualities of parent-child relationships and the qualities of sibling relationships across a 2-year period in adolescence. Participants were first- and second-born siblings (M age = 14.94 years for firstborns and M age = 12.46 years for secondborns) from 185 predominantly White, working and middle-class families. In home interviews, siblings reported on their dyadic family relationships. For reports of parent-child warmth but not parent-child conflict, results were consistent with sibling differentiation theory: Increasing differences between siblings over time in parent-child warmth were linked to trajectories of increasing warmth and decreasing conflict in the sibling relationship as reported by firstborns, and increasing warmth in the sibling relationship as reported by secondborns. The findings support the view that sibling differentiation may be a strategy for managing sibling conflict and rivalry.

Nest-building Hymenoptera have been a major testing ground for theories of parental investment and sex allocation. Investment has usually been estimated by the likely costs of offspring provisioning, ignoring other aspects of parental care. Using three experimental treatments, we estimated the costs of egg-laying and provisioning separately under field conditions in a digger wasp Ammophila pubescens. In one treatment, we increased the provisioning effort required per offspring by removing alternate prey items as they were brought to the nest. In two other treatments, we reduced parental effort by either preventing females from provisioning alternate nests or preventing them from both ovipositing and provisioning. Our results indicate that both egg-laying and provisioning represent significant costs of reproduction, expressed as differences in productivity but not survival. A trade-off-based model suggests that other components of parental care such as nest initiation may also represent significant costs. Costs of egg production and nest initiation are probably similar for male and female offspring, so that taking them into account leads to a less male-biased expected sex ratio. Mothers compensated only partially for prey removal in terms of the total provisions they gave to individual offspring.

Previous research has not always found that boys and girls are treated differently in rural India. However estimates of the effect of gender on parental investments could be biased if girls end up in larger families due to son-biased stopping rules. Using a novel identification strategy that exploits that gender at conception is random, we document that boys receive more childcare time than girls, they are breastfed longer and they get more vitamin supplementation. Compared to other developing countries, boys have an advantage in height and weight relative to girls. Neither greater needs nor anticipated family size explain the results. PMID:24575163

Research on differential susceptibility to rearing suggests that infants with difficult temperaments are disproportionately affected by parenting and child care quality, but a major U.S. child care study raises questions as to whether quality of care influences social adjustment. One thousand three hundred sixty-four American children from reasonably diverse backgrounds were followed from 1 month to 11 years with repeated observational assessments of parenting and child care quality, as well as teacher report and standardized assessments of children's cognitive-academic and social functioning, to determine whether those with histories of difficult temperament proved more susceptible to early rearing effects at ages 10 and 11. Evidence for such differential susceptibility emerges in the case of both parenting and child care quality and with respect to both cognitive-academic and social functioning. Differential susceptibility to parenting and child care quality extends to late middle childhood. J. Belsky, D. L. Vandell, et al.'s (2007) failure to consider such temperament-moderated rearing effects in their evaluation of long-term child care effects misestimates effects of child care quality on social adjustment.

The assimilation capacity (AC) hypothesis for the evolution of endothermy predicts that the maternal basal metabolic rate (BMR) should be positively correlated with the capacity for parental investment. In this study, we provide a unique test of the AC model based on mice from a long-term selection experiment designed to produce divergent levels of BMR. By constructing experimental families with cross-fostered litters, we were able to control for the effect of the mother as well as the type of pup based on the selected lines. We found that mothers with genetically determined high levels of BMR were characterized by higher parental investment capacity, measured as the offspring growth rate. We also found higher food consumption and heavier visceral organs in the females with high BMR. These findings suggested that the high-BMR females have higher energy acquisition abilities. When the effect of the line type of a foster mother was controlled, the pup line type significantly affected the growth rate only in the first week of life, with young from the high-BMR line type growing more rapidly. Our results support the predictions of the AC model. PMID:23282996
Full Text Available This paper argues that closing the gender gap in land and other productive resources can provide a “triple dividend” of gender equality, food security and climate management, thereby offering a cost-effective approach to the pursuit of the Sustainable Development Goals. However, climate change compounds the structural barriers to gender equality that women farmers face, rapidly shrinking the window of opportunity to realize this triple dividend. Yet climate policies largely overlook the gender gap in agriculture.The growing literature on the gender gap aims to better quantify its implications for agricultural productivity but does not provide a framework to prioritize policy responses. To complement these econometric efforts, this paper proposes a three-step methodology to assist policy-makers in developing countries in disentangling the opportunities and trade-offs of different policies and interventions to close the gender gap that impedes climate-smart agriculture (CSA for women.Barrier and risk analyses are increasingly used to identify public instruments that can catalyze climate smart investments. Building on this proven methodology, the paper first develops a table that clusters barriers to CSA into nine independent risk categories. Second, it overlays a gender analysis upon this gender-neutral barrier and risk table to identify gender-differentiated risks and barriers to CSA. Third, it maps identified gender-neutral and differentiated investment risks against possible remedial public policy instruments.The analysis suggests that about half of identified CSA investment risks have a higher probability of occurrence for women farmers than for men farmers. Furthermore, women farmers might face additional gender-specific barriers, mostly linked to their disproportionate responsibility for unpaid domestic and care work, the risk of violence and unequal power relations with men in the household and community. Targeted interventions will be

Theory predicts that parents should invest less in dependent offspring with lower reproductive value, such as those with a high risk of predation. Moreover, high predation risk can favor reduced parental activity when such activity attracts nest predators. Yet, the ability of parents to assess ambient nest-predation risk and respond adaptively remains unclear, especially where nest-predator assemblages are diverse and potentially difficult to assess. We tested whether variation in parental investment by a multi-brooded songbird (Brewer's Sparrow, Spizella breweri) in an environment (sagebrush steppe) with diverse predators was predicted by ambient nest-predation risk or direct experience with nest predation. Variation among eight sites in ambient nest-predation risk, assayed by daily probabilities of nest predation, was largely uncorrelated across four years. In this system risk may therefore be unpredictable, and aspects of parental investment (clutch size, egg mass, incubation rhythms, nestling-feeding rates) were not related to ambient risk. Moreover, investment at first nests that were successful did not differ from that at nests that were depredated, suggesting parents could not assess and respond to territorylevel nest-predation risk. However, parents whose nests were depredated reduced clutch sizes and activity at nests attempted later in the season by increasing the length of incubation shifts (on-bouts) and recesses (off-bouts) and decreasing trips to feed nestlings. In this unpredictable environment parent birds may therefore lack sufficient cues of ambient risk on which to base their investment decisions and instead rely on direct experience with nest predation to inform at least some of their decisions. ?? 2010 The Cooper Ornithological Society.

We investigated whether circulating glucocorticoids and androgens are correlated with reproductive investment in smallmouth bass (Micropterus dolomieu), a teleost fish with sole paternal care. Circulating cortisol and androgens prior to and 25 min following a standardized 3 min emersion stressor were quantified for non-reproductive and parental fish across the parental care period. To experimentally investigate the influence of reproductive investment on endocrine parameters, we manipulated brood size (reduced, enlarged, sham-treated, or unmanipulated) 24h prior to sampling parental fish. We predicted that fish guarding offspring would exhibit increased androgens and baseline cortisol levels, and an attenuated cortisol response to the stressor when compared with non-reproductive individuals. We further predicted that these effects would scale with reproductive investment. As predicted, parental care-providing fish exhibited lower post-stress plasma cortisol concentrations than non-reproductive fish. This difference was strongest early during parental care. However, no differences in baseline or post-stress cortisol concentrations were detected among parents guarding offspring with varying brood sizes. There was, however, a trend for parental fish to exhibit an increased cortisol response following brood manipulation, regardless of the direction of change in brood size, a response that likely reflected disturbance. No differences were found in baseline cortisol concentrations. Circulating androgens were found to be highest during early parental care, and no differences were found among parents guarding manipulated broods. Collectively, these findings demonstrate that the endocrine stress response is affected by reproductive status, but the response in this model species does not appear to be scaled according to reproductive investment as predicted by life-history theory.

This study examined how child temperament was related to parents' time spent accessible to and interacting with their 2-year-olds. Bivariate analyses indicated that both fathers and mothers spent more time with temperamentally challenging children than easier children on workdays, but fathers spent less time with challenging children than easier children on non-workdays. After accounting for work hours, some associations between temperament and fathers' workday involvement dropped to non-significance. For fathers, work hours also moderated the relation between irregular temperament and workday play. For mothers, work hours moderated the relation between both difficult and irregular temperament and workday interaction. Mothers also spent more time with girls (but not boys) who were temperamentally irregular. Results speak to the influence of child temperament on parenting behavior, and the differential construction of parenting roles as a function of child characteristics and patterns of work.

The texture, composition and ages of chondrites have all been used to argue that the parent bodies of these meteorites did not undergo planetary differentiation. Without a core, these planetesimals could not have generated planetary magnetic fields, hence chondrites are predicted to be unmagnetized. Here, we test this hypothesis by applying synchrotron x-ray microscopy to the metallic melt veins in the metamorphosed H chondrite breccia Portales Valley. We find that tetrataenite nanostructures in these veins are uniformly magnetized, suggesting that the H chondrite parent body generated a stable, 10 µT ancient field. We also performed alternating field (AF) demagnetization on bulk silicate-rich portions of Portales Valley, finding that both the large grain size of the metal in these subsamples and the presence of tetrataenite hinder the reliable interpretation of these measurements. Based on 40Ar/39Ar dating and the metallographic cooling rate, we propose that this field inferred from x-ray microscopy was generated 100 Myr after solar system formation and lasted >5 Myr. These properties are consistent with a dynamo field generated by core solidification, implying that the H chondrite parent body was partially differentiated. This conclusion is supported by our analyses of the H4 chondrite Forest Vale, which show that H chondrite magnetization is unlikely to be a relic signature of early nebular or solar wind fields (Getzin et al., this meeting; Oran et al., this meeting). We propose that partial differentiation could result form prolonged accretion over millions of years, possibly in two stages. In this scenario, the earliest accreted material melted from the radioactive decay of abundant 26Al, forming a core and rocky achondritic mantle, while the later accreted material was less metamorphosed, forming an undifferentiated crust. We demonstrate that, with the inclusion of an insulating regolith, the thermal evolution of such a body is consistent with the measured
Time diaries of sibling pairs from the PSID-CDS are used to determine whether maternal time investments compensate for or reinforce birth-weight differences among children. The findings demonstrate that the direction and degree of differential treatment vary by mother's education. Less-educated mothers devote more total time and more educationally oriented time to heavier-birth-weight children, whereas better-educated mothers devote more total and more educationally oriented time to lower-birth-weight children. The compensating effects observed among highly educated mothers are substantially larger than the reinforcing effects among the least-educated mothers. The findings show that families redistribute resources in ways that both compensate for and exacerbate early-life disadvantages. PMID:22865101

Full Text Available The current research tests the hypothesis that women have an evolved mate value calibration adaptation that functions to raise or lower their standards in a long-term mate according to their own mate value. A woman's physical attractiveness is a cardinal component of women's mate value. We correlated observer-assessed physical attractiveness (face, body, and overall with expressed preferences for four clusters of mate characteristics (N = 214: (1 hypothesized good-gene indicators (e.g., masculinity, sexiness; (2 hypothesized good investment indicators (e.g., potential income; (3 good parenting indicators (e.g., desire for home and children, and (4 good partner indicators (e.g., being a loving partner. Results supported the hypothesis that high mate value women, as indexed by observer-judged physical attractiveness, expressed elevated standards for all four clusters of mate characteristics. Discussion focuses on potential design features of the hypothesized mate-value calibration adaptation, and suggests an important modification of the trade-off model of women's mating. A minority of women—notably those low in mate value who are able to escape male mate guarding and the manifold costs of an exposed infidelity—will pursue a mixed mating strategy, obtaining investment from one man and good genes from an extra-pair copulation partner (as the trade-off model predicts. Since the vast majority of women secure genes and direct benefits from the same man, however, most women will attempt to secure the best combination of all desired qualities from the same man.

Full Text Available In seabirds, equal bi-parental care is the rule, as it is considered crucial for raising chicks successfully because seabirds forage in an environment with unpredictable and highly variable food supply. Frigatebirds forage in poor tropical waters, yet males reduce and even stop parental care soon after chick brooding, leaving the female to provision the chick alone for an extended fledging period. Using bird-borne tracking devices, male and female Christmas Island Frigatebirds (Fregata andrewsi were investigated during the brooding, late chick rearing and post-fledging period to examine whether sexes exhibit foraging strategies that may be linked to differential breeding investments. During brooding, males and females showed similar foraging behaviour under average marine productivity of oceanic waters close to the colony, but males shifted to more distant and more productive habitats when conditions deteriorated to continue with reduced chick provisioning. During the late chick rearing period, females progressively increased their foraging range to the more distant but productive marine areas that only males had visited during brooding. Birds spent the non-breeding period roosting in highly productive waters of the Sunda Shelf. The sex-specific utilisation of three different foraging habitats with different primary productivity (oceanic, coastal, and shelf areas allowed for temporal and spatial segregation in the exploitation of favourable habitats which seems to enable each sex to optimise its foraging profitability. In addition, post-fledging foraging movements of females suggest a biennial breeding cycle, while limited information on males suggests the possibility of an annual breeding cycle.

Social immunization (SI) is a horizontal transfer of immunity that protects naive hosts against infection following exposure to infected nestmates. While mainly documented in eusocial insects, non-social species also share similar ecological features which favour the development of group-level immunity. Here, we investigate SI in Tenebrio molitor by pairing naive females with a pathogen-challenged conspecific for 72 h before measuring a series of immune and fitness traits. We found no evidence for SI, as beetles who cohabited with a live pathogen-challenged conspecific were not better protected against bacterial challenge. However, exposure to a heat-killed-bacteria-challenged conspecific appeared to increase pathogen tolerance, which manifested in differential fitness investment. Our results together suggest that T. molitor do respond to immune-related cues in the social environment, despite not showing a classic immunization response as predicted. © 2018 The Author(s).
Full Text Available Sexual conflict drives the coevolution of sexually antagonistic traits, such that an adaptation in one sex selects an opposing coevolutionary response from the other. Although many adaptations and counteradaptations have been identified in sexual conflict over mating interactions, few are known for sexual conflict over parental investment. Here we investigate a possible coevolutionary sequence triggered by mate desertion in the burying beetle Nicrophorus vespilloides, where males commonly leave before their offspring reach independence. Rather than suffer fitness costs as a consequence, our data suggest that females rely on the male's absence to recoup some of the costs of larval care, presumably because they are then free to feed themselves on the carcass employed for breeding. Consequently, forcing males to stay until the larvae disperse reduces components of female fitness to a greater extent than caring for young singlehandedly. Therefore we suggest that females may have co-evolved to anticipate desertion by their partners so that they now benefit from the male's absence.

While a large literature has investigated the role of parental human capital on children's well-being, relatively little is known regarding the effects of human capital investment in children on long run outcomes of parents. In this study we explore the human capital variations created by the 1974 Tanzania education reform to estimate the effect of children's primary schooling attainment on parental survival. Using 5,026,315 census records from 1988, 2002, and 2012, we show that the 1974 reform resulted in an additional 1.1 years (31%) of educational attainment among exposed cohorts. Using the reform as instrument for child education we find that each additional year of primary schooling in children resulted in a 3.7 percentage point reduction (p human capital gains generated by reforms are shared with the parental generation.

Evidence for the presence of past dynamos from magnetic studies of meteorites can provide key information on the nature and evolution of parent bodies. However, the suggestion of a past core dynamo for the CV parent body based on the study of the Allende meteorite has led to a paradox: a core dynamo requires differentiation, evidence for which is missing in the meteorite record. The key parameter used to distinguish core dynamo versus external field mechanisms is absolute field paleointensity, with high values (>>1 μT) favoring the former. Here we explore the fundamental requirements for absolute field intensity measurement in the Allende meteorite: single domain grains that are non-interacting. Magnetic hysteresis and directional data define strong magnetic interactions, negating a standard interpretation of paleointensity measurements in terms of absolute paleofield values. The Allende low field magnetic susceptibility is dominated by magnetite and FeNi grains, whereas the magnetic remanence is carried by an iron sulfide whose remanence-carrying capacity increases with laboratory cycling at constant field values, indicating reordering. The iron sulfide and FeNi grains are in close proximity, providing mineralogical context for interactions. We interpret the magnetization of Allende to record the intense early solar wind with metal-sulfide interactions amplifying the field, giving the false impression of a higher field value in some prior studies. An undifferentiated CV parent body is thus compatible with Allende's magnetization. Early solar wind magnetization should be the null hypothesis for evaluating the source of magnetization for chondrites and other meteorites.

Caregivers who smoke and have children with asthma are an important group for intervention. Home-based interventions successfully reduce asthma morbidity, yet are costly. This study evaluated the financial return on investment (ROI) of the Parents of Asthmatics Quit Smoking (PAQS) program, a combined asthma education and smoking cessation intervention. Participants included caregivers (n = 224) that smoked, had a child with asthma, and were enrolled in a Medicaid managed care plan. Participants received nurse-delivered asthma education and smoking counseling in three home visits. Program implementation costs were estimated, and healthcare expenses were obtained from insurance claims data 12 months pre- and 12 months post intervention. ROI was calculated for all participants, children <6 years, children 6-18 years, and children with moderate/severe persistent asthma. Total program implementation cost was $34,481. After intervention, there was increased mean annual refills of beta-agonist (0.51 pre, 1.64 post; P < 0.001), and controller medications (0.65 pre, 2.44 post; P < 0.001). Reductions were found in mean annual emergency department visits (0.33 pre, 0.14 post; P < 0.001), hospitalizations (0.23 pre, 0.08 post; P < 0.001), and outpatient visits (2.33 pre, 1.45 post, P < 0.001). The program had negative ROI (-21.8%) for the entire sample. The ROI was positive (+106.9) for children <6 years, negative (-150.3) for children 6-18, and negligible for moderate/severe persistent asthma (+6.9%). PAQS was associated with increased medication use and decreased healthcare utilization. While the overall ROI for PAQS was negative, PAQS had a positive ROI for caregivers of young children with asthma. Copyright © 2012 Wiley Periodicals, Inc.

This longitudinal study examines the association between child gender and child aggression via parents' physical control, moderated by parents' gender-role stereotypes in a sample of 299 two-parent families with a 3-year-old child in the Netherlands. Fathers with strong stereotypical gender-role attitudes and mothers were observed to use more physical control strategies with boys than with girls, whereas fathers with strong counterstereotypical attitudes toward gender roles used more physical control with girls than with boys. Moreover, when fathers had strong attitudes toward gender roles (stereotypical or counterstereotypical), their differential treatment of boys and girls completely accounted for the gender differences in children's aggressive behavior a year later. Mothers' gender-differentiated parenting practices were unrelated to gender differences in child aggression. © 2016 The Authors.

Increased utilization of in vitro fertilization (IVF) to treat infertility has resulted in a growing twin birthrate. Despite early childhood risks, twins have fewer psychosocial problems in middle childhood than singleton children. This study proposes that parents' conformity expectations for children have differential effects on parent-child relationships for twin and singleton children, which indirectly explains twins' more optimum psychosocial adjustment. Parental conformity expectations, parent-child relationship satisfaction, and children's emotional, behavioral, and attention problems were assessed in a sample of 288 6- to 12-year-old IVF-conceived twins and singletons. Overall, parents of twins had higher expectations for child conformity to parent rules than singleton parents. Path models demonstrate that twin status and parental expectations for child conformity interact to influence parent-child relationships, and this interaction indirectly accounted for differences in twins' and singletons' psychosocial adjustment. Findings suggest parenting constructs have differential influences on the association between twin status and parent-child relationships. Parenting research, predominantly conducted with singletons, should be reexamined before applying existing research to twin children and their families. (c) 2015 APA, all rights reserved).

Although the relationship between parenting and outcomes for children and adolescents has been examined, differences between maternal and paternal parenting styles have received less attention, particularly in the case of late adolescents. As a result, this article examines the relationship between late adolescents' perceptions of their mothers'…

Although various theories describe mechanisms leading to differential parenting of boys and girls, there is no consensus about the extent to which parents do treat their sons and daughters differently. The last meta-analyses on the subject were conducted more than fifteen years ago, and changes in gender-specific child rearing in the past decade are quite plausible. In the current set of meta-analyses, based on 126 observational studies (15,034 families), we examined mothers’ and fathers’ differential use of autonomy-supportive and controlling strategies with boys and girls, and the role of moderators related to the decade in which the study was conducted, the observational context, and sample characteristics. Databases of Web of Science, ERIC, PsychInfo, Online Contents, Picarta, and Proquest were searched for studies examining differences in observed parental control of boys and girls between the ages of 0 and 18 years. Few differences were found in parents’ use of control with boys and girls. Parents were slightly more controlling with boys than with girls, but the effect size was negligible (d = 0.08). The effect was larger, but still small, in normative groups and in samples with younger children. No overall effect for gender-differentiated autonomy-supportive strategies was found (d = 0.03). A significant effect of time emerged: studies published in the 1970s and 1980s reported more autonomy-supportive strategies with boys than toward girls, but from 1990 onwards parents showed somewhat more autonomy-supportive strategies with girls than toward boys. Taking into account parents’ gender stereotypes might uncover subgroups of families where gender-differentiated control is salient, but based on our systematic review of the currently available large data base we conclude that in general the differences between parenting of boys versus girls are minimal.

Parents' differential treatment (PDT) is a common family dynamic that has been linked to youth development and well-being, including adjustment problems and poor sibling relationships. Much less is known, however, about the developmental course of PDT and the conditions under which parents treat their children differently in adolescence and young adulthood. This study examined longitudinal changes in mothers' and fathers' differential warmth and conflict with their two offspring from early adolescence through young adulthood and examined parents' experiences of individual stress (depressive symptoms and role overload) and marital difficulties as time-varying correlates of (changes in) PDT. We also tested crossover effects to determine whether mothers' experiences of individual stress and marital difficulties were linked to fathers' differential treatment, and vice versa. Participants were mothers, fathers, and two siblings from 246 Mexican-origin families who were interviewed in their homes on three occasions over 8 years. Multilevel models revealed that mothers' and fathers' differential conflict with their two children increased until middle adolescence and then declined into young adulthood, but there were no changes over time for parents' differential warmth. In general, both mothers' and fathers' levels of differential treatment were exacerbated by their own experiences of individual stress and marital difficulties and also by the experiences of their spouses. However, in some cases, greater stress than usual was linked to less differential treatment than usual. © 2017 Family Process Institute.

Gene expression from both parental genomes is required for completion of embryogenesis. Differential methylation of each parental genome has been observed in mouse and human preimplantation embryos. It is possible that these differences in methylation affect the level of gene transcripts from each parental genome in early developing embryos. The aim of this study was to investigate if there is a parent-specific pattern of BRCA1 expression in human embryos and to examine if this affects embryo development when the embryo carries a BRCA1 or BRCA2 pathogenic mutation. Differential parental expression of ACTB, SNRPN, H19 and BRCA1 was semi-quantitatively analysed by minisequencing in 95 human preimplantation embryos obtained from 15 couples undergoing preimplantation genetic diagnosis. BRCA1 was shown to be differentially expressed favouring the paternal transcript in early developing embryos. Methylation-specific PCR showed a variable methylation profile of BRCA1 promoter region at different stages of embryonic development. Embryos carrying paternally inherited BRCA1 or 2 pathogenic variants were shown to develop more slowly compared with the embryos with maternally inherited BRCA1 or 2 pathogenic mutations. This study suggests that differential demethylation of the parental genomes can influence the early development of preimplantation embryos. Expression of maternal and paternal genes is required for the completion of embryogenesis. PMID:27677417

Full Text Available In recent years, the construction of China’s power grid has experienced rapid development, and its scale has leaped into the first place in the world. Accurate and effective prediction of power grid investment can not only help pool funds and rationally arrange investment in power grid construction, but also reduce capital costs and economic risks, which plays a crucial role in promoting power grid investment planning and construction process. In order to forecast the power grid investment of China accurately, firstly on the basis of analyzing the influencing factors of power grid investment, the influencing factors system for China’s power grid investment forecasting is constructed in this article. The method of grey relational analysis is used for screening the main influencing factors as the prediction model input. Then, a novel power grid investment prediction model based on DE-GWO-SVM (support vector machine optimized by differential evolution and grey wolf optimization algorithm is proposed. Next, two cases are taken for empirical analysis to prove that the DE-GWO-SVM model has strong generalization capacity and has achieved a good prediction effect for power grid investment forecasting in China. Finally, the DE-GWO-SVM model is adopted to forecast power grid investment in China from 2018 to 2022.

The hypothalamic-pituitary-adrenal (HPA) axis is a critical component of the body's stress-response neurobiological system, and its development and functioning are shaped by the social environment. Much of our understanding of the effects of the caregiving environment on the HPA axis is based on (a) parenting in young children and (b) individual maternal stressors, such as depression. Yet, less is known about how parenting behaviors and maternal stressors interact to influence child cortisol regulation, particularly in older children. With an ethnically diverse sample of 199 mothers and their early adolescent children (M=11.00years; 54% female), a profile analytic approach was used to investigate how multiple phenotypes of maternal stress co-occur and moderate the relation between parenting behaviors and youths' diurnal cortisol rhythms. Latent profile analysis yielded 4 profiles: current parenting stress, concurrent parenting and childhood stress, childhood stress, and low stress. For mothers with the concurrent parenting and childhood stress profile, inconsistent discipline, poor parental supervision, and harsh caregiving behaviors each were related to flattened diurnal cortisol rhythms in their adolescents. For mothers with the current parenting stress and childhood stress profiles, their use of inconsistent discipline was associated with flattened diurnal cortisol rhythms in their adolescents. For mothers with the low stress profile, none of the parenting behaviors was related to their adolescents' cortisol regulation. Findings suggest that based on mothers' stress profile, parenting behaviors are differentially related to youths' diurnal cortisol rhythms. Implications for parenting interventions are discussed.

Data from a survey of 200 young adults assessed whether the early nonshared environment, specifically parental differential treatment, was associated with romantic relationship distress through its effects on sibling jealousy, attachment styles, and self-esteem. Individuals who received equal affection from their parents in comparison to their sibling reported equal jealousy between themselves and their sibling, had higher self-esteem, more secure attachment styles, and less romantic relationship distress. Receiving differential parental affection, regardless of whether the participant or their sibling was favored, was associated with more negative models of self and others, which in turn were associated with greater romantic relationship distress. Results indicate that early within-family experiences may be particularly relevant for later healthy romantic relationship functioning.

This study examined associations between changes in sibling relationships and changes in parental differential treatment and corresponding changes in children's adjustment. One hundred thirty-three families were assessed at 3 time points. Parents rated children's externalizing problems, and children reported on sibling relationship quality, parental differential treatment, and depressive symptoms. On average, older siblings were 10, 12, and 16 years old, and younger siblings were 8, 10, and 14 years old at Waves 1, 2, and 3, respectively. Results from hierarchical linear modeling indicated that as sibling relationships improved over time, children's depressive symptoms decreased over time. In addition, as children were less favored over their siblings over time, children's externalizing problems increased over time. Findings highlight the developmental interplay between the sibling context and children's adjustment. Copyright 2006 APA, all rights reserved).

We studied chick survival of the Mountain Plover (Charadrius montanus) in Montana and found that chicks tended by females had higher survival rates than chicks tended by males, and that chick survival generally increased during the nesting season. Differences in chick survival were most pronounced early in the nesting season, and may be related to a larger sample of nests during this period. When compared to information about the nest survival of male- and female-tended plover nests, our chick data suggest a trade-off for adult plovers between the egg and chick phases of reproduction. Because Mountain Plover pairs have clutches at two nests at two different locations and show differential success between the sexes during the egg and chick phases, we offer that the Mountain Plover breeding system favours optimizing annual recruitment in a dynamic ecologic setting driven by annually unpredictable drought, grazing, and predation pressures.

This study examines the relationship between levels of psychological distress in substance-dependent mothers and their differential response to a dyadic parent-child intervention. A sample of 66 mothers who were receiving treatment for substance abuse, as well as a simultaneous parenting intervention, were interviewed pre and post-treatment on measures of psychological distress, adult and child trauma history, parental reflective functioning, and child social-emotional development. Additionally, clinicians provided assessments of the parent-child relationships. As anticipated, trauma histories for mothers and children, children's social emotional development, and parental reflective functioning were associated with aspects of maternal psychological distress. Kruskal-Wallis and subsequent Wilcoxson signed rank tests revealed that women with highest levels of baseline psychological distress showed significant improvements in psychological functioning post-treatment while women with moderately elevated levels of psychological distress did not. Women who were most distressed at baseline showed increased levels of parental reflective functioning post-treatment while women with moderate and lower levels of baseline psychological distress showed improvements on clinician-rated assessments of parent-child relationships. Chi Square analyses showed that parents who endorsed the highest levels of distress at baseline reported that their children's risk status regarding social-emotional development decreased post-treatment. Despite similarities in substance dependence, mothers in this sample had different needs and outcomes in the context of this parenting intervention due to variation in mental health. Given this variation, parenting interventions for substance-dependent mothers need to account for the individual differences in levels of psychological distress. Copyright © 2015 Elsevier Ltd.

To examine the relations between preterm birth, parenting behavior during early childhood, cognitive development, and social-emotional outcomes at Kindergarten entry, and to determine whether parenting behavior differentially influences this developing system in children born preterm compared to children born full-term. The nationally representative sample comprised 3600 full-term and 1300 preterm children born in the US in the year 2001. All children who entered Kindergarten and who participated in data collection at 9 months, 24 months, and Kindergarten entry were included in the study. Measures of parenting behavior were collected at 9 and 24 months and cognitive development at 24 months via home visits. Social-emotional outcomes were assessed at Kindergarten entry via parent and teacher report. Multiple-sample Structural Equation Modeling was used to analyze group differences in a model whereby early childhood parenting behavior predicted cognitive outcomes, and social-emotional outcomes at Kindergarten entry, and indirectly predicted social-emotional outcomes via early cognitive processes. The full sample developmental model indicated excellent fit to the data. Preterm birth status indirectly influenced social-emotional outcomes at Kindergarten entry via its effect on early childhood parenting behavior and cognitive development. The multi-sample model revealed significant differences in the way in which early parenting behavior exerted its influence on outcomes at Kindergarten entry in preterm children compared to full-term children. For preterm children, parenting indirectly influenced social-emotional outcomes via early cognitive functioning. Findings highlight the importance of early identification and targeted parenting programs to support early cognitive development in preterm children. Copyright © 2014 Elsevier Ltd.

A key challenge clinicians face when considering differential diagnoses is whether the patient data have been adequately collected. Insufficient data may inadvertently lead to premature closure of the diagnostic process. This study aimed to test the hypothesis that the application of a mnemonic checklist helps to stimulate more patient data collection, thus leading to better diagnostic consideration. A total of 88 final year medical students were assigned to either an educational intervention group or a control group in a non-equivalent group post-test only design. Participants in the intervention group received a tutorial on the use of a mnemonic checklist aimed to minimize cognitive errors in clinical decision-making. Two weeks later, the participants in both groups were given a script concordance test consisting of 10 cases, with 3 items per case, to assess their clinical decisions when additional data are given in the case scenarios. The Mann-Whitney U-test performed on the total scores from both groups showed no statistical significance (U = 792, z = -1.408, p = 0.159). When comparisons were made for the first half and the second half of the SCT, it was found that participants in the intervention group performed significantly better than participants in the control group in the first half of the test, with median scores of 9.15 (IQR 8.00-10.28) vs. 8.18 (IQR 7.16-9.24) respectively, U = 642.5, z = -2.661, p = 0.008. No significant difference was found in the second half of the test, with the median score of 9.58 (IQR 8.90-10.56) vs. 9.81 (IQR 8.83-11.12) for the intervention group and control group respectively (U = 897.5, z = -0.524, p = 0.60). Checklist use in differential diagnoses consideration did show some benefit. However, this benefit seems to have been traded off by the time and effort in using it. More research is needed to determine whether this benefit could be translated into clinical practice after repetitive
Understanding the differentiating impacts of the communication strategies of a high involvement service (investment advisory services) and a high involvement product (precious jewellery) on customer satisfaction and loyalty.
While marketing literature has largely focused on high and low involvement purchases and the positive relationship between customer satisfaction and loyalty; the differentiating impacts of communication strategies for a high involvement service and a high involvement product on customer satisfaction and loyalty has received little academic attention.

Although negative parenting behavior and peer status are independently associated with childhood conduct problems (e.g., oppositional defiant disorder (ODD)), relatively little is known about their interplay, particularly in relation to differentiated measures of positive and negative peer regard. To improve the specificity of the association of negative parenting behavior and peer factors with ODD, we explored the potential interaction of parenting and peer status in a sample of 169 five-to ten-year-old ethnically diverse children with and without attention-deficit/hyperactivity disorder (ADHD) assessed using multiple measures (i.e., rating scales, interview) and informants (i.e., parents, teachers). Controlling for children's age, sex, number of ADHD symptoms, and parents' race-ethnicity, peer acceptance inversely predicted and inconsistent discipline, harsh punishment, and peer rejection were each positively associated with ODD symptom severity. Interactive influences were also evident such that inconsistent discipline and harsh punishment each predicted elevated ODD but only among children experiencing low peer acceptance or high peer rejection. These findings suggest that supportive environments, including peer acceptance, may protect children from negative outcomes associated with inconsistent discipline and harsh punishment. Findings are integrated with theories of social support, and we additionally consider implications for intervention and prevention. © 2013 Wiley Periodicals, Inc.

This study draws on attachment theory and social learning theory and uses data from the National Survey of Families and Households to examine the differential effects of childhood family disruptions on adult well-being. Comparisons are made between adults who experienced parental divorce, adults who experienced parental death, and adults who were raised in intact families (N = 4,341). The present study differs from previous research by making direct comparisons between different family disruption groups, assessing the effects of family disruptions that occur before age 19, and including multiple measures of adult well-being as dependent variables. Consistent with hypotheses and inferences made from comparisons with adults from intact families, adults who experienced parental divorce report lower levels of parent-child relationship quality, higher levels of self-confidence, and lower levels of depression than adults who experienced parental death during childhood. Therefore, studies that fail to take type of childhood family disruption into account will lead to inaccurate and misleading conclusions about the effects of these experiences on adult outcomes.
Mesosiderites and howardites are regolith samples of differentiated asteroids. Instrumental neutron activation analysis (INAA) data on whole rock howardites and mesosiderite silicates show that the composition of howardites and mesosiderites are similar, and intermediate between those of eucrites and diogenites. The mesosiderites Mincy, Lowicz and Veramin show an enrichment in light REE and have an REE pattern that is qualitatively similar to that in terrestrial basalts thought to have been formed by small degrees of partial melting. Attempts to model the REE abundances in these mesosiderites indicates that they most likely formed by approx. 2 to 4% partial melting of a source containing low abundances of the rare earths. Since numerous properties separate mesosiderite silicates from howardites, it is clear that they are not samples of a well-mixed regolith from a single parent body. If regolith stirring is efficient on small parent bodies, then mesosiderites and howardites originated on separate parent bodies. Rare earth element patterns give evidence for remelting and fractional crystallization of preexisting cumulates and sequential melting episodes. The mesosiderites appear to contain a slightly greater abundance of diogenite-like material and certainly contain a greater abundance of large olivine clasts. These observations suggest that the mesosiderite parent body crust was more complexly fractionated than the howardite parent body crust. The latter appears to have been dominated by quenched basalt flows

Objective: To explore radioresistance correlative genes in IRM-2 inbred mouse. Methods: The total RNA was extracted from spleen cells of IRM-2 and their parent 615 and ICR/JCL mouse. The mRNA differential display technique was used to analyze gene expression differences. Each differential bands were amplified by PCR, cloned and sequenced. Results: There were 75 differential expression bands appearing in IRM-2 mouse but not in 615 and ICR/JCL mouse. Fifty-two pieces of cDNA sequences were got by sequencing. Twenty-one expressed sequence tags (EST) that were not the same as known mice genes were found and registered by comparing with GenBank database. Conclusion: Twenty-one EST denote that radioresistance correlative genes may be in IRM-2 mouse, which have laid a foundation for isolating and identifying radioresistance correlative genes in further study.

This study employs findings from social comparison research to investigate adolescents' comparisons with siblings with regard to parental treatment. The sibling comparison hypothesis was tested on a sample of 516 two-child families by examining whether gender, self-esteem, and emotionality-which have been found in previous research to moderate social comparison-also moderate sibling comparison as reflected by siblings' own evaluations of differential parental treatment. Results supported a moderating effect for self-esteem and emotionality but not gender. The sibling comparison process was further examined by using a structural equation model in which parenting toward each child was associated with the adjustment of that child and of the child's sibling. Evidence of the "sibling barricade" effect-that is, parenting toward one child being linked with opposite results on the child's sibling as on the target child-was found in a limited number of cases and interpreted as reflecting a sibling comparison process. For older siblings, emotionality and self-esteem moderated the sibling barricade effect but in the opposite direction as predicted. Results are discussed in terms of older siblings' increased sensitivity to parenting as well as the report of differential parenting reflecting the child's level of comfort and benign understanding of differential parenting, which buffers the child against environmental vicissitudes evoking sibling comparison processes.

Parents' differential treatment is a common family dynamic that has been linked to youth's well-being in childhood and adolescence in European American families. Much less is known, however, about this family process in other ethnic groups. The authors examined the longitudinal associations between parents' differential treatment (PDT) and both depressive symptoms and risky behaviors of Mexican-origin sibling pairs from early adolescence through young adulthood. They also tested the moderating roles of cultural orientations as well as youth age, gender and sibling dyad gender constellation in these associations. Participants were mothers, fathers, and 2 siblings from 246 Mexican-origin families who participated in individual home interviews on 3 occasions over 8 years. Multilevel models revealed that, controlling for dyadic parent-child relationship qualities (i.e., absolute levels of warmth and conflict), adolescents who had less favorable treatment by mothers relative to their sibling reported more depressive symptoms and risky behavior, on average. Findings for fathers' PDT emerged at the within-person level indicating that, on occasions when adolescents experienced less favorable treatment by fathers than usual, they reported more depressive symptoms and risky behavior. However, some of these effects were moderated by youth age and cultural socialization. For example, adolescents who experienced relatively less paternal warmth than their siblings also reported poorer adjustment, but this effect did not emerge for young adults; such an effect also was significant for unfavored youth with stronger but not weaker cultural orientations.

A family systems perspective directs attention to the potentially different experiences and perspectives of family members. This study examined parents' differential treatment (PDT) of siblings, discrepancies between parent and youth reports of PDT, and their links with relationships between adolescents and their mothers and fathers across three years. Participants were first- (Time 1 M age = 15.71, SD = 1.07) and secondborn (Time 1 M age = 13.18, SD = 1.29) siblings from 381, predominately white, working and middle class families. Analyses revealed that siblings' perceptions of being favored predicted less conflict with and greater warmth from both mothers and fathers, primarily for secondborn adolescents. Larger discrepancies between maternal and youth reports of differential affection were linked to more maternal conflict and less warmth for firstborns. These findings may suggest a hierarchy within families: parents may serve as referents for firstborns and firstborns as referents for secondborns.

The brain is one of the most energetically expensive organs in the vertebrate body. Consequently, the energetic requirements of encephalization are suggested to impose considerable constraints on brain size evolution. Three main hypotheses concerning how energetic constraints might affect brain evolution predict covariation between brain investment and (1) investment into other costly tissues, (2) overall metabolic rate, and (3) reproductive investment. To date, these hypotheses have mainly been tested in homeothermic animals and the existing data are inconclusive. However, there are good reasons to believe that energetic limitations might play a role in large-scale patterns of brain size evolution also in ectothermic vertebrates. Here, we test these hypotheses in a group of ectothermic vertebrates, the Lake Tanganyika cichlid fishes. After controlling for the effect of shared ancestry and confounding ecological variables, we find a negative association between brain size and gut size. Furthermore, we find that the evolution of a larger brain is accompanied by increased reproductive investment into egg size and parental care. Our results indicate that the energetic costs of encephalization may be an important general factor involved in the evolution of brain size also in ectothermic vertebrates. © 2014 The Author(s).

Social anxiety is one of the most commonly reported mental health problems among adolescents, and it has been suggested that parenting style influences an adolescent's level of anxiety. A context-dependent effect of oxytocin on human social behavior has been proposed; however, research on the oxytocin gene (OXT) has mostly been reported without considering contextual factors. This study investigated the interactions between parenting style and polymorphic variations in the OXT gene in association with social anxiety symptoms in a community sample of adolescents (n = 1,359). Two single nucleotide polymorphisms linked to OXT, rs4813625 and rs2770378, were genotyped. Social anxiety and perceived parenting style were assessed by behavioral questionnaires. In interaction models adjusted for sex, significant interaction effects with parenting style were observed for both variants in relation to social anxiety. The nature of the interactions was in line with the differential susceptibility framework for rs4813625, whereas for rs2770378 the results indicated a diathesis-stress type of interaction. The findings may be interpreted from the perspective of the social salience hypothesis of oxytocin, with rs4813625 affecting social anxiety levels along a perceived unsafe-safe social context dimension.

This study examined reciprocal links between parental differential treatment, siblings' perception of partiality, and self-worth with 3 waves of data from 384 adolescent sibling dyads. Results suggest that birth-order status was significantly associated with self-worth and perception of maternal and paternal differential treatment. There was a consistent across-time effect of self-worth on perception of parental partiality for later born siblings, but not earlier born siblings, and a consistent effect of differential treatment on perception of partiality for earlier born but not later born siblings. The results contribute new insight into the associations between perception of differential parenting and adolescents' adjustment and the role of birth order.

Theory predicts that males have a limited amount of resources to invest in reproduction, suggesting a trade-off between traits that enhance mate acquisition and those that enhance fertilization success. Here, we investigate the relationship between pre- and post-copulatory investment by comparing the mating behaviour and reproductive morphology of four European and five North American populations of the dung fly Sepsis punctum (Diptera) that display a reversal of sexual size dimorphism (SSD). We show that the geographic reversal in SSD between the continents (male biased in Europe, female biased in North America) is accompanied by differential investment in pre- vs. post-copulatory traits. We find higher remating rates in European populations, where larger males acquire more matings and consequently have evolved relatively larger testes and steeper hyper-allometry with body size. American populations, in sharp contrast, display much reduced, if any, effect of body size on those traits. Instead, North American males demonstrate an increased investment in mate acquisition prior to copulation, with more mounting attempts and a distinctive abdominal courtship display that is completely absent in Europe. When controlling for body size, relative female spermathecal size is similar on both continents, so we find no direct evidence for the co-evolution of male and female internal reproductive morphology. By comparing allopatric populations of the same species that apparently have evolved different mating systems and consequently SSD, we thus indirectly demonstrate differential investment in pre- vs. post-copulatory mechanisms increasing reproductive success. © 2012 The Authors.

This longitudinal study examines the association between child gender and child aggression via parents' physical control, moderated by parents' gender-role stereotypes in a sample of 299 two-parent families with a 3-year-old child in the Netherlands. Fathers with strong stereotypical gender-role
Species with paternal care show less exaggerated sexual ornamentation than those in which males do not care, although direct benefits from paternal care can vastly exceed the indirect benefits of mate choice. Whether condition-dependent handicaps can signal parenting ability is controversial. The good-parent process predicts the evolution of honest signals of parental investment, whereas the differential-allocation model suggests a trade-off between the attractiveness of a mate and his care-p...
Full Text Available Besides other explanatory variables, parenting styles and parental violence might also be responsible for setting a path towards overweight/obesity in childhood. While this association has consistently been observed for adults, findings for adolescents still remain scarce and inconsistent. Therefore, the goal of this study is to add evidence on this topic for children and adolescents. Analyses are based on a sample of 1729 German, ninth-grade students. To analyze associations between parenting dimensions and weight status, non-parametric conditional inference trees were applied. Three gender-specific pathways for a heightened risk of overweight/obesity were observed: (1 female adolescents who report having experienced severe parental physical abuse and medium/high parental warmth in childhood; (2 male adolescents who report having experienced low or medium parental monitoring in childhood; and (3 this second pathway for male adolescents is more pronounced if the families receive welfare. The importance of promoting parenting styles characterized by warmth and a lack of physical abuse is also discussed. This is one of only a few studies examining the association of parenting dimensions/parental physical abuse and weight status in adolescence. Future studies should include even more parenting dimensions, as well as parental physical abuse levels, in order to detect and untangle gender-specific effects on weight status.

This study examined differential symptom functioning (DSF) in ADHD symptoms across Malay and Chinese children in Malaysia. Malay (N=571) and Chinese (N=254) parents completed the Disruptive Behavior Rating Scale, which lists the DSM-IV ADHD symptoms. DSF was examined using the multiple indicators multiple causes (MIMIC) structural equation modeling procedure. Although DSF was found for a single inattention (IA) symptom and three hyperactivity-impulsivity (HI) symptoms, all these differences had low effect sizes. Controlling for these DSF, Chinese children had higher IA and HI latent factor scores. However the effect sizes were small. Together, these findings suggest adequate support for invariance of the ADHD symptoms across these ethno-cultural groups. The implications of the findings for cross-cultural invariance of the ADHD symptoms are discussed.

Males that follow alternative reproductive tactics might differ in their investment into testis development and sperm production. The resource-allocation hypothesis predicts that males following a sneaker tactic should invest more into sperm production than dominant territorial males which should invest more into mate guarding. This hypothesis is supported by studies in species where individual males cannot switch between tactics (fixed tactics). Here we present the first data for a species where males can switch between tactics (plastic tactics). We studied African striped mice (Rhabdomys pumilio) in captivity, mimicking three tactics observed in the field: philopatric group-living males, singly-housed males representing roaming males, and group-living breeding males. We measured quantitative and qualitative reproductive traits, as well as serum and testis hormone concentrations. We found no support for the resource-allocation hypothesis, since breeding and singly-housed males invested similarly in testes and sperm. However, philopatric males had significantly smaller testes and epididymides, lower sperm counts, lower testosterone and higher corticosterone levels than males of the two other tactics. Philopatric males did not reach a larger body mass than singly-housed males with well developed reproductive traits, indicating that they did not trade investment in sperm production against growth. Interestingly, testis testosterone concentrations of philopatric males did not differ from those of other males. Our data suggest that philopatric males are reproductively suppressed by the breeding male, but might be ready to increase their serum testosterone levels when social and environmental conditions allow for this physiological switch accompanying the behavioral switch between tactics.

Individuals of different quality may have different investment strategies, shaping responses to experimental manipulations, thereby rendering the detection of such patterns difficult. However, previous clutch-size manipulation studies have infrequently incorporated individual differences in quality. To examine costs of incubation and reproductive investment in relation to changes in clutch size, we enlarged and reduced natural clutch sizes of four and five eggs by one egg early in the incubation period in female common eiders (Somateria mollissima), a sea duck with an anorectic incubation period. Females that had produced four eggs (lower quality) responded to clutch reductions by deserting the nest more frequently but did not increase incubation effort in response to clutch enlargement, at the cost of reduced hatch success of eggs. Among birds with an original clutch size of five (higher quality), reducing and enlarging clutch size reduced and increased relative body mass loss respectively without affecting hatch success. In common eiders many females abandon their own ducklings to the care of other females. Enlarging five-egg clutches led to increased brood care rate despite the higher effort spent incubating these clutches, indicating that the higher fitness value of a large brood is increasing adult brood investment. This study shows that the ability to respond to clutch-size manipulations depends on original clutch size, reflecting differences in female quality. Females of low quality were reluctant to increase investment at the cost of lower hatch success, whereas females of higher quality apparently have a larger capacity both to increase incubation effort and brood care investment.

A difficult or undercontrolled temperament, as well as harsh parental discipline or a lack of warmth, has long been regarded as risk factors for the development of externalizing problems. In addition, it has been suggested that children with difficult temperament are especially susceptible to rearing influences. We investigated the impact of early temperament and parenting and their interactions on externalizing behavior at school age. Participants were 148 boys and 160 girls from a prospective longitudinal study on a high-risk sample. At ages 3 months and 2 years, temperament was assessed by a highly structured parent interview and standardized behavioral observations. Maternal parenting was assessed by videotaped behavioral observation and a parent questionnaire. Externalizing problems at age 8 years were measured by the Child Behavior Checklist. Using hierarchical linear regression analyses, we found that externalizing problems were predicted by psychosocial adversity and poor self-control, whereas no main effect for restrictive parenting or maternal empathy was found. Fearful-inhibited boys were positively affected by empathic and sensitive parenting, whereas girls who were low in self-control and/or fearful developed less externalizing problems with restrictive parenting. Our results partly support the differential susceptibility hypothesis. In addition, they point toward gender-specific pathways in the development of externalizing problems.

There is a dearth of empirical studies aimed at examining the impact of differential cultural adaptation of evidence-based clinical and prevention interventions. This prevention study consisted of a randomized controlled trial aimed at comparing the impact of 2 differentially culturally adapted versions of the evidence-based parenting intervention known as Parent Management Training, the Oregon Model (PMTOR). The sample consisted of 103 Latina/o immigrant families (190 individual parents). Each family was allocated to 1 of 3 conditions: (a) a culturally adapted PMTO (CA), (b) culturally adapted and enhanced PMTO (CE), and (c) a wait-list control. Measurements were implemented at baseline (T1), treatment completion (T2) and 6-month follow up (T3). Multilevel growth modeling analyses indicated statistically significant improvements on parenting skills for fathers and mothers (main effect) at 6-month follow-up in both adapted interventions, when compared with the control condition. With regard to parent-reported child behaviors, child internalizing behaviors were significantly lower for both parents in the CE intervention (main effect), compared with control at 6-month follow-up. No main effect was found for child externalizing behaviors. However, a Parent × Condition effect was found indicating a significant reduction of child externalizing behaviors for CE fathers compared with CA and control fathers at posttest and 6-month follow-up. Present findings indicate the value of differential cultural adaptation research designs and the importance of examining effects for both mothers and fathers, particularly when culturally focused and gender variables are considered for intervention design and implementation.

Individuals who believe that intelligence can be improved with effort (an incremental theory of intelligence) and who approach challenges with the goal of improving their understanding (a learning goal) tend to have higher academic achievement. Furthermore, parent praise is associated with children's incremental theories and learning goals. However, the influences of parental criticism, as well as different forms of praise and criticism (e.g., process vs. person), have received less attention. We examine these associations by analyzing two existing datasets (Study 1: N = 317 first to eighth graders; Study 2: N = 282 fifth and eighth graders). In both studies, older children held more incremental theories of intelligence, but lower learning goals, than younger children. Unexpectedly, the relation between theories of intelligence and learning goals was nonsignificant and did not vary with children's grade level. In both studies, overall perceived parent praise positively related to children's learning goals, whereas perceived parent criticism negatively related to incremental theories of intelligence. In Study 2, perceived parent process praise was the only significant (positive) predictor of children's learning goals, whereas perceived parent person criticism was the only significant (negative) predictor of incremental theories of intelligence. Finally, Study 2 provided some support for our hypothesis that age-related differences in perceived parent praise and criticism can explain age-related differences in children's learning goals. Results suggest that incremental theories of intelligence and learning goals might not be strongly related during childhood and that perceived parent praise and criticism have important, but distinct, relations with each motivational construct.

To specify parent reaction to a mental disorder in the child and to develop differential approaches to psychosocial family interventions. Authors studied parents (mostly mothers) of 140 children with schizophrenia spectrum disorders, 100 children with autistic disorders and 85 children with mental retardation. Along with psychiatric examination of the parents, it was used psychometric scales ECI and CGSQ. Authors specified emotional and behavioral characteristics of the parents' reaction as common for all diseases studied as well peculiar for separated forms of mental diseases in children. The factors (cognitive, emotional and behavioral) determining the targets of differentiated therapeutic interventions were singled out. The stress coping strategies for parents are formulated.

The origin of remanent magnetization in the CV carbonaceous chondrite Allende has been a longstanding mystery. The possibility of a core dynamo like that known for achondrite parent bodies has been discounted because chondrite parent bodies are assumed to be undifferentiated. Here we report that Allende's magnetization was acquired over several million years (Ma) during metasomatism on the parent planetesimal in a > 20 microtesla field 8-9 Ma after solar system formation. This field was present too recently and directionally stable for too long to have been the generated by the protoplanetary disk or young Sun. The field intensity is in the range expected for planetesimal core dynamos (Weiss et al. 2010), suggesting that CV chondrites are derived from the outer, unmelted layer of a partially differentiated body with a convecting metallic core (Elkins-Tanton et al. 2010). This suggests that asteroids with differentiated interiors could be present today but masked under chondritic surfaces. In fact, CV chondrites are spectrally similar to many members of the Eos asteroid family whose spectral diversity has been interpreted as evidence for a partially differentiated parent asteroid (Mothe-Diniz et al. 2008). CV chondrite spectral and polarimetric data also resemble those of asteroid 21 Lutetia (e.g., Belskaya et al. 2010), recently encountered by the Rosetta spacecraft. Ground-based measurements of Lutetia indicate a high density of 2.4-5.1 g cm-3 (Drummond et al. 2010), while radar data seem to rule out a metallic surface composition (Shepard et al. 2008). If Rosetta spacecraft measurements confirm a high density and a CV-like surface composition for Lutetia, then we propose Lutetia may be an example of a partially differentiated carbonaceous chondrite parent body. Regardless, the very existence of primitive achondrites, which contain evidence of both relict chondrules and partial melting, are prima facie evidence for the formation of partially differentiated bodies.

Previous studies on the relation between testosterone (T) levels and parenting have found ample evidence for the challenge hypothesis, demonstrating that high T levels inhibit parental involvement and that becoming a parent is related to a decrease in T levels in both mothers and fathers. However,

It has been shown that following exposure to mild perinatal adversity, children have greater susceptibility to both the negative and positive aspects of their subsequent environment. In a large population-based cohort study (N = 1,776), we investigated whether mild perinatal adversity moderated the association between maternal harsh parenting and children's hair cortisol levels, a biomarker of chronic stress. Mild perinatal adversity was defined as late preterm birth (gestational age at birth of 34-37 weeks, 6 days) or small for gestational age (birth weight between the 2.5th and 10th percentile for full term gestational age). Harsh parenting was assessed by maternal self-report at 3 years. Children's hair cortisol concentrations were measured from hair samples collected at age 6. There were no significant bivariate associations between mild perinatal adversities and harsh parenting and hair cortisol. However, mild perinatal adversities moderated the association between maternal harsh parenting and hair cortisol levels. Children with mild perinatal adversity had lower cortisol levels if parented more harshly and higher cortisol levels in the absence of harsh parenting than children who did not experience mild perinatal adversity. These results provide further evidence that mild perinatal adversity is a potential marker of differential susceptibility to environmental influences. © 2017 Wiley Periodicals, Inc.

Behavioral and physiological responses to unpredictable changes in environmental conditions are, in part, mediated by glucocorticoids (corticosterone in birds). In polymorphic species, individuals of the same sex and age display different heritable melanin-based color morphs, associated with physiological and reproductive parameters and possibly alternative strategies to cope with variation in environmental conditions. We examined whether the role of corticosterone in resolving the trade-off between self-maintenance and reproductive activities covaries with the size of melanin-based spots displayed on the ventral body side of male barn owls. Administration of corticosterone to simulate physiological stress in males revealed pronounced changes in their food-provisioning rates to nestlings compared to control males. Corticosterone-treated males with small eumelanic spots reduced nestling provisioning rates as compared to controls, and also to a greater degree than did corticosterone-treated males with large spots. Large-spotted males generally exhibited lower parental provisioning and appear insensitive to exogenous corticosterone suggesting that the size of the black spots on the breast feathers predicts the ability to cope with stressful situations. The reduced provisioning rate of corticosterone-treated males caused a temporary reduction in nestling growth rates but, did not affect fledgling success. This suggests that moderately elevated corticosterone levels are not inhibitory to current reproduction but rather trigger behavioral responses to maximize lifetime reproductive success.

Guided by Bowen theory, we investigated the relationships between parent-child triangulation, parental differential treatment (PDT), sibling warmth, and individual depressive symptoms in a sample of 77 sibling dyads, aged 18-25 years, recruited through undergraduate classes at a U.S. public University. Results of the actor-partner interdependence models suggested that being triangulated into parental conflict was positively related to both siblings' perception of PDT; however, as one sibling felt triangulated, the other perceived reduced levels of PDT. For both siblings, the perception of higher levels of PDT was related to decreased sibling warmth and higher sibling warmth was associated with fewer depressive symptoms. The implications of these findings for research and the treatment of depression in the college-aged population are discussed. © 2016 American Association for Marriage and Family Therapy.

Hair loss is commonly used as an indicator of well being in primate facilities, yet it has been shown to also occur in otherwise healthy pregnant and postpartum females. There is significant variability in the incidence of hair loss during these important developmental periods, reasons for which remain unclear. We studied female rhesus monkeys (Macaca mulatta, n = 47) with and without hair loss in pregnancy/postpartum. We hypothesized that, similar to previously published reports, pregnancy would result in an increased likelihood of hair loss, and that hair loss would be correlated with higher hair cortisol concentrations (HCCs). We further hypothesized that hair loss among pregnant females is related to differential maternal investment. We studied a subset of monkeys (n = 26) from mid-to-late pregnancy through peak lactation, some of which exhibited hair loss in the perinatal period (n = 15), and some of which did not (n = 11). We examined fetal measurements, infant birth weight, infant growth rate, and milk yield volume (MYV) in the first 30 days as indices of investment. We found that pregnant monkeys showed a greater incidence of hair loss across the study year (χ 2 (2) = 6.55, P = 0.038), and that mothers with hair loss had significantly higher HCCs in pregnancy than those without (F (2,28) = 3.8, P = 0.017, η p 2 = 0.21). HCCs in pregnancy were correlated with severity of hair loss in the neonatal period (r (37) = 0.42, P = 0.008). Moreover, HCCs in pregnancy were positively correlated with infant birth weight (r (12) = 0.56, P = 0.038), infant growth rate (r (12) = 0.64, P = 0.014), and MYV (r (11) = 0.85, P hair loss in some monkeys, especially during the birthing season, may be a signal of greater physiological stress during pregnancy and differential investment by mothers to their offspring.

The purpose of the study was to determine whether well-established associations between authoritarian parenting and adolescent adjustment pertain to conservative Protestant (CP) families. Structural equation modeling was used to test paths from biological fathers' authoritarian parenting to adolescent adjustment in 65 CP versus 170 comparison families in the Nonshared Environment and Adolescent Development Study (NEAD; D. Reiss et al., 1994). The hypothesis that adolescents in CP families would be less harmed by authoritarian parenting than would adolescents in control families was partially supported: Authoritarian parenting directly predicted greater externalizing and internalizing for adolescents in control families but not for adolescents in CP families. In contrast, parents' religious affiliation failed to moderate the negative associations between authoritarian parenting and positive adjustment. Understanding family processes specific to the CP subculture is important for helping these families raise competent children. (c) 2006 APA, all rights reserved.

This study examined children's parasympathetic nervous system (PNS) regulation, which was indexed by respiratory sinus arrhythmia (RSA) during rest, reactivity, and recovery episodes, and sex as moderators of predicted relations between observed intrusive parenting and later observer-rated child behavior problems. Child-caregiver dyads (N=250; 50% girls; 46% Latino/a) completed a series of laboratory assessments yielding independent measures of intrusive parenting at age 4, PNS regulation at age 6, and child behavior problems at age 8. Results indicated that intrusive parenting was related to more internalizing problems among boys who showed low RSA reactivity (i.e., PNS withdrawal from pre-startle to startle challenge), but RSA reactivity did not moderate this relation among girls. Interestingly, RSA recovery (i.e., PNS activation from startle challenge to post-startle) moderated these relations differently for boys and girls. For girls with relatively low RSA post-startle (i.e., less recovery), intrusive parenting was positively related to both internalizing and externalizing problems. However, the reverse was true for boys, such that there was a significant positive relation between intrusive parenting and later externalizing problems among boys who evidenced relatively high RSA post-startle (i.e., more recovery). Findings provide evidence for the moderation of intrusive caregiving effects by children's PNS regulation while highlighting the differential patterning of these relations across distinct phases of the regulatory response and as a function of child sex.

Parental warmth and autonomy granting are commonly thought of as protective factors against substance use among Caucasians. However, limited research has examined whether associations between parenting dimensions and substance use outcomes are the same or different among Asian Americans. A final analytic sample of 839 college students was used to test whether race (Caucasian vs. Asian American) moderated the relations between parenting dimensions and substance use outcomes across Caucasians and Asian Americans. We utilized the Parental Bonding Instrument (Parker, Tupling, & Brown, 1979) to measure maternal and paternal warmth, encouragement of behavioral freedom, and denial of psychological autonomy. Multivariate regression models controlling for covariates including age, gender, and paternal education indicated four significant parenting by race interactions on alcohol problems and/or marijuana use. Specifically, maternal warmth was inversely associated with both alcohol problems and marijuana use among Caucasians but not among Asian Americans. Both maternal and paternal denial of psychological autonomy were positively associated with alcohol problems among Caucasians but not among Asian Americans. Consistent with emerging cross-cultural research, the associations between parenting dimensions and substance use behaviors observed in Caucasian populations may not be readily generalized to Asian Americans. These findings highlight the importance of considering different parenting dimensions in understanding substance use etiology among Asian Americans. Future research should use longitudinal data to replicate these findings across development and seek to identify other parenting dimensions that may be more relevant for Asian American youth.

Recent genetic evidence suggests that the most important environmental influences on normal and pathologic development are those that are not shared by siblings in the same family. We sought to determine the relationship between differences in parenting styles and depressive symptoms and antisocial behavior in adolescence, and to compare the influence of these nonshared experiences with genetic influences. We studied 708 families with at least two same-sexed adolescent siblings who were monozygotic twins (93 families), dizygotic twins (99 families), ordinary siblings (95 families), full siblings in step families (181 families), half siblings in step families (110 families), and genetically unrelated siblings in step families (130 families). Data on parenting style were collected by questionnaire and by video recording of interaction between parents and children. Almost 60% of variance in adolescent antisocial behavior and 37% of variance in depressive symptoms could be accounted for by conflictual and negative parental behavior directed specifically at the adolescent. In contrast, when a parent directed harsh, aggressive, explosive, and inconsistent parenting toward the sibling, we found less psychopathologic outcome in the adolescent. Parenting behavior directed specifically at each child in the family is a major correlate of symptoms in adolescents. Furthermore, harsh parental behavior directed at a sibling may have protective effects for adolescents, a phenomenon we call the "siblin barricade."

Though the adverse consequences of perceived housing discrimination have been documented, little is known about whether such experience undermines one's social capital in a neighborhood and even less is about whether and how this relationship is altered by neighborhood features. We proposed a framework that simultaneously considers within-individual and between-neighborhood processes. We applied multilevel structural equation models to data from Philadelphia (n = 9987) and found that (a) perceived housing discrimination was negatively associated with one's social capital even after other confounders were considered, (b) this negative association could be partly explained by the proliferated daily stress and anxiety mechanisms, (c) differential exposures to neighborhood social disadvantage accounted for the variation in social capital across neighborhoods, and (d) the adverse association between perceived housing discrimination and social capital could be attenuated by neighborhood stability. The findings suggested that appropriate interventions should buffer the negative association of perceived housing discrimination with social capital. Copyright © 2018 Elsevier Inc.

The purpose of this study was to investigate the intra-familial relationships between parental reports of feeding practices used with siblings in the same family, and to evaluate whether differences in feeding practices are related to differences in siblings' eating behaviours. Eighty parents of two sibling children completed measures assessing their feeding practices and child eating behaviours. Parents reported using greater restrictive feeding practices with children who were fussier and desired to drink more than their sibling. Parents reported using more pressure to eat with siblings who were slower to eat, were fussier, emotionally under-ate, enjoyed food less, were less responsive to food, and were more responsive to internal satiety cues. Restriction and pressure to eat appear to be part of the non-shared environment which sibling children experience differently. These feeding practices may be used differently for children in the same family in response to child eating behaviours or other specific characteristics.

Behavioral inhibition (BI) is a temperament characterized by social reticence and withdrawal from unfamiliar or novel contexts and conveys risk for social anxiety disorder. Developmental outcomes associated with this temperament can be influenced by children’s caregiving context. The convergence of a child’s temperamental disposition and rearing environment is ultimately expressed at both the behavioral and neural levels in emotional and cognitive response patterns to social challenges. The present study used functional neuroimaging to assess the moderating effects of different parenting styles on neural response to peer rejection in two groups of adolescents characterized by their early childhood temperament (Mage = 17.89 years, N= 39, 17 males, 22 females; 18 with BI; 21 without BI). The moderating effects of authoritarian and authoritative parenting styles were examined in three brain regions linked with social anxiety: ventrolateral prefrontal cortex (vlPFC), striatum, and amygdala. In youth characterized with BI in childhood, but not in those without BI, diminished responses to peer rejection in vlPFC were associated with higher levels of authoritarian parenting. In contrast, all youth showed decreased caudate response to peer rejection at higher levels of authoritative parenting. These findings indicate that BI in early life relates to greater neurobiological sensitivity to variance in parenting styles, particularly harsh parenting, in late adolescence. These results are discussed in relation to biopsychosocial models of development. PMID:25588884

Investors are a heterogeneous group, they may be large or small, rich or poor, expert or lay man and not all investors need equal degree of protection (Mayya, 1996). An investor has three objectives while investing his money, namely safety of invested money, liquidity position of invested money and return on investment. The return on investment may further be divided into capital gain and the rate of return on investment as interest or dividend. Among all investment options available, securities are considered the most challenging as well as rewarding. Securities include shares, debentures, derivatives, units of mutual funds, Government securities etc. An investor may be an individual or corporate legal entity investing funds with a view to derive maximum economic advantage from investment such as rate of return, capital appreciation, marketability, tax advantage and convenience of investment.The Capital market facilitates mobilization of savings of individuals and pools them into reservoir of capital which can be used for the economic development of a country. An efficient capital market is essential for raising capital by the corporate sector of the economy and for the protection of the interest of investors in corporate securities. There arises a need to strike a balance between raising of capital for economic development on one side and protection of investors on the other. Unless the interests of investors are protected, raising of capital, by corporates is not possible. Like, the primary objective of a senior citizenís asset allocation is the generation of regular income.

Although depressive symptoms are common during adolescence, little research has examined gene-environment interaction on youth depression. This study chose the brain-derived neurotrophic factor (BDNF) gene, tested the interaction between a functional polymorphism resulting amino acid substitution of valine (Val) to methionine (Met) in the proBDNF protein at codon 66 (Val66Met), and maternal parenting on youth depressive symptoms in a sample of 780 community adolescents of Chinese Han ethnicity (aged 11-17, M = 13.6, 51.3 % females). Participants reported their depressive symptoms and perceived maternal parenting. Results indicated the BDNF Val66Met polymorphism significantly moderated the influence of maternal warmth-reasoning, but not harshness-hostility, on youth depressive symptoms. Confirmatory model evaluation indicated that the interaction effect involving warmth-reasoning conformed to the differential-susceptibility rather than diathesis-stress model of person-X-environment interaction. Thus, Val carriers experienced less depressive symptoms than Met homozygotes when mothering was more positive but more symptoms when mothering was less positive. The findings provided evidence in support of the differential susceptibility hypothesis of youth depressive symptoms and shed light on the importance of examining the gene-environment interaction from a developmental perspective.

Both depressive and somatic symptoms are significant predictors of parenting and coparenting problems. However, despite clear evidence of their co-occurrence, no study to date has examined the association between depressive-somatic symptoms clusters and parenting and coparenting. The current research sought to identify and cross-validate clusters of cognitive-affective depressive symptoms and nonspecific somatic symptoms, as well as to test whether clusters would differ on parenting and coparenting problems across three independent samples of mothers. Participants in Studies 1 and 3 consisted of 409 and 652 community mothers, respectively. Participants in Study 2 consisted of 162 mothers exposed to intimate partner violence. All participants prospectively completed self-report measures of depressive and nonspecific somatic symptoms and parenting (Studies 1 and 2) or coparenting (Study 3). Across studies, three depression-somatic symptoms clusters were identified: no symptoms, high depression and low nonspecific somatic symptoms, and high depression and nonspecific somatic symptoms. The high depression-somatic symptoms cluster was associated with the highest levels of child physical maltreatment risk (Study 1) and overt-conflict coparenting (Study 3). No differences in perceived maternal competence (Study 2) and cooperative and undermining coparenting (Study 3) were found between the high depression and low somatic symptoms cluster and the high depression-somatic symptoms cluster. The results provide novel evidence for the strong associations between clusters of depression and nonspecific somatic symptoms and specific parenting and coparenting problems. Cluster stability across three independent samples suggest that they may be generalizable. The results inform preventive approaches and evidence-based psychotherapeutic treatments.

This study investigates the relation between socio-economic parental position (education and occupation) and child death in Mozambique using data from the Mozambican Demographic and Health Survey carried out between March and July 1997. The analysis included 9142 children born within 10 years...... before the survey. In spite of the Western system of classification used in the study, the results partly showed a parental socio-economic gradient of infant and child mortality in Mozambique. Father's education seemed to reflect the family's social standing in the Mozambique context, showing a strong...... statistical association with postneonatal and child mortality. However, maternal education as a measure of socio-economic position was not statistically significantly associated with child mortality. This finding may partly be explained by the extreme hardships experienced by the country (civil war...

In France, one in 10 residents has immigrated mainly from North Africa, West Africa or the Caribbean including the French West Indies. However little is known about how parents from these regions behave when they migrate to countries that have different cultural norms. It is therefore important to determine how ethno-cultural background affects parental behavior and subsequent child mental health in the context of immigration. The objectives are: 1) to compare negative parenting behaviors of French residents from diverse ethno-cultural backgrounds 2) to examine the relationship between parental region of origin and child mental health, and 3) to investigate the extent to which ethno-cultural context moderates the effect of parenting styles on child mental health. A cross-sectional study was conducted in 2005 in 100 schools in South-East France. The Dominic Interactive and the parent-reported Strengths and Difficulties Questionnaire were used to assess child psychopathology. The Parent Behavior and Attitude Questionnaire was used to assess parenting styles. The final sample included data on 1,106 mother and child dyads. Caring and punitive attitudes were significantly different across mothers as a function of region of origin. This association was stronger for punitive attitudes with the highest prevalence in the Caribbean/African group, while mothers from Maghreb were more similar to French natives. Differences in caring behaviors were similar though less pronounced. Among children of Maghrebian descent, punitive parenting was associated with an increased risk of internalizing disorders while this association was weaker among children of African and Afro-Caribbean descent. Parental region of origin is an important component of both parenting styles and their effect on child mental health. Interventions on parenting should consider both the region of origin and the differential impact of origin on the effect of parenting styles, thus allowing for a finer

Differential susceptibility theory proposes that a subset of individuals exist who display enhanced susceptibility to both negative (risk-promoting) and positive (development-enhancing) environments. This experiment represents the first attempt to directly test this assumption by exposing children in the experimental group to both negative and positive feedback using puppet role-plays. It thereby serves as an empirical test as well as a methodological primer for testing differential susceptibility. Dutch children (N=190, 45.3% girls) between the ages of 4 and 6years participated. We examined whether negative and positive feedback would differentially affect changes in positive and negative affect, in prosocial and antisocial intentions and behavior, depending on children's negative emotionality. Results show that on hearing negative feedback, children in the experimental group increased in negative affect and decreased in positive affect more strongly than children in the control group. On hearing positive feedback, children in the experimental group tended to increase in positive affect and decrease in prosocial behavior. However, changes in response to negative or positive feedback did not depend on children's negative emotionality. Moreover, using reliable change scores, we found support for a subset of "vulnerable" children but not for a subset of "susceptible" children. The findings offer suggestions to guide future differential susceptibility experiments. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background It was proposed that differentially-expressed genes, aside from genetic variations affecting protein processing and functioning, between hybrid and its parents provide essential candidates for studying heterosis or hybrid vigor. Based our serial analysis of gene expression (SAGE data from an elite Chinese super-hybrid rice (LYP9 and its parental cultivars (93-11 and PA64s in three major tissue types (leaves, roots and panicles at different developmental stages, we analyzed the transcriptome and looked for candidate genes related to rice heterosis. Results By using an improved strategy of tag-to-gene mapping and two recently annotated genome assemblies (93-11 and PA64s, we identified 10,268 additional high-quality tags, reaching a grand total of 20,595 together with our previous result. We further detected 8.5% and 5.9% physically-mapped genes that are differentially-expressed among the triad (in at least one of the three stages with P-values less than 0.05 and 0.01, respectively. These genes distributed in 12 major gene expression patterns; among them, 406 up-regulated and 469 down-regulated genes (P Conclusion We improved tag-to-gene mapping strategy by combining information from transcript sequences and rice genome annotation, and obtained a more comprehensive view on genes that related to rice heterosis. The candidates for heterosis-related genes among different genotypes provided new avenue for exploring the molecular mechanism underlying heterosis.

In rodent species, sexual differentiation of the brain for many reproductive processes depends largely on estradiol. This was recently confirmed again by using the α-fetoprotein knockout (AFP-KO) mouse model, which lacks the protective actions of α-fetoprotein against maternal estradiol and as a result represents a good model to determine the contribution of prenatal estradiol to the sexual differentiation of the brain and behavior. Female AFP-KO mice were defeminized and masculinized with regard to their neuroendocrine responses as well as sexual behavior. Since parental behavior is also strongly sexually differentiated in mice, we used the AFP-KO mouse model here to ask whether parental responses are differentiated prenatally under the influence of estradiol. It was found that AFP-KO females showed longer latencies to retrieve pups to the nest and also exhibited lower levels of crouching over the pups in the nest in comparison to WT females. In fact, they resembled males (WT and AFP-KO). Other measures of maternal behavior, for example the incidence of infanticide, tended to be higher in AFP-KO females than in WT females but this increase failed to reach statistical significance. The deficits observed in parental behavior of AFP-KO females could not be explained by any changes in olfactory function, novelty recognition or anxiety. Thus our results suggest that prenatal estradiol defeminizes the parental brain in mice. PMID:20109458

Intuition suggests that corporate investment should be decreasing in financing constraints. We show that even when financing is obtained using a standard debt contract and there is symmetric information between the firm and outside investors, the relation is actually U-shaped. We thus provide a new...... theoretical explanation for the recent empirical findings of Cleary et al. (2007). We split up the endogenously implied financing costs and propose a trade-off between expected liquidation costs and second-best investment costs. For rather unconstrained firms, the risk of costly liquidation dominates the cost...

Unconformable surfaces separating Precambrian crystalline basement and overlying Proterozoic to Cambrian sedimentary rocks provide an exceptional opportunity to examine the role of primitive soil ecosystems in weathering and resultant formation of saprolite (weathered rock retaining rock structure) and regolith (weathered rock without rock structure), but many appear to have been affected by burial diagenesis and hydrothermal fluid flow, leading some researchers to discount their suitability for such studies. We examine one modern weathering profile (Cecil series), four Cambrian paleoweathering profiles from the North American craton (Squaw Creek, Franklin Mountains, Core SQ-8, and Core 4), one Neoproterozoic profile (Sheigra), and one late Paleoproterozoic profile (Baraboo), to test the hypothesis that these paleoweathering profiles do provide evidence of primitive terrestrial weathering despite their diagenetic and hydrothermal overprinting, especially additions of potassium. We employ an integrated approach using (1) detailed thin-section investigations to identify characteristic pedogenic features associated with saprolitization and formation of well-drained regoliths, (2) electron microprobe analysis to identify specific weathered and new mineral phases, and (3) geochemical mass balance techniques to characterize volume changes during weathering and elemental gains and losses of major and minor elements relative to the inferred parent materials. There is strong pedogenic evidence of paleoweathering, such as clay illuviation, sepic-plasmic fabrics, redoximorphic features, and dissolution and alteration of feldspars and mafic minerals to kaolinite, gibbsite, and Fe oxides, as well as geochemical evidence, such as whole-rock losses of Na, Ca, Mg, Si, Sr, Fe, and Mn greater than in modern profiles. Evidence of diagenesis includes net additions of K, Ba, and Rb determined through geochemical mass balance, K-feldspar overgrowths in overlying sandstone sections, and
The crude divorce rate has been increasing steadily for over a decade in China. Consequently, more and more children have to face the challenge of growing up in single parent families. The current study investigated the mediating effects of problem-oriented and emotion-oriented coping on the relationship between parental attachment and psychological resilience among a sample of Chinese adolescents from single parent families and intact families. Participants were 975 high school students (44.30% males; aged 15-19 years, M = 16.32 years, SD = 0.74), 871 from intact families and 104 from single parent families. Structural equation modeling showed that security in maternal attachment was positively associated with resilience through the indirect effect of reduced emotion-oriented coping among adolescents from single parent families. Among adolescents from intact families, security in maternal attachment was both directly associated with resilience and indirectly through enhanced problem-oriented and reduced emotion-oriented coping. Security in paternal attachment was associated with resilience both directly and indirectly through enhanced problem-oriented coping as well among those from intact families. Female adolescents exhibited significantly lower levels of resilience than male adolescents did regardless of the marital status of their parents. Limitations and suggestions for future research are discussed.

Insensitive and unresponsive caregiving during infancy has been linked to externalizing behavior problems during childhood and adolescence. The 7-repeat (7r) allele of the dopamine D4 receptor (DRD4) gene has meta-analytically been associated with a heightened susceptibility to adverse as well as supportive environments. In the present study, we examined long-term effects of early maternal care, DRD4 genotype and the interaction thereof on externalizing and internalizing psychopathology during adolescence. As part of an ongoing epidemiological cohort study, early maternal care was assessed at child's age 3 months during a nursing and playing situation. In a sample of 296 offspring, externalizing and internalizing symptoms were assessed using a psychiatric interview conducted at age 15 years. Parents additionally filled out a questionnaire on their children's psychopathic behaviors. Results indicated that adolescents with the DRD4 7r allele who experienced less responsive and stimulating early maternal care exhibited more symptoms of ADHD and CD/ODD as well as higher levels of psychopathic behavior. In accordance with the hypothesis of differential susceptibility, 7r allele carriers showed fewer ADHD symptoms and lower levels of psychopathic behavior when exposed to especially beneficial early caregiving. In contrast, individuals without the DRD4 7r allele proved to be insensitive to the effects of early maternal care. This study replicates earlier findings with regard to an interaction between DRD4 genotype and early caregiving on externalizing behavior problems in preschoolers. It is the first one to imply continuity of this effect until adolescence. Copyright © 2014 Elsevier Ltd. All rights reserved.

To assess associations between parental control or parental emotional support and current tobacco, alcohol or cannabis use among 12-18-year-old students, according to gender and family structure (intact family, reconstituted family, single-parent family). A cross-sectional survey was conducted in a national representative sample in France (2003) of 6-12th grade students (N = 16,532), as a part of the ESPAD study (European Study Project on Alcohol and Other Drugs). The self-administered questionnaire included questions on last 30 days' consumption of alcohol, tobacco and cannabis as well as on socio-demographic characteristics, school characteristics, and some simple questions on parental control and parental emotional support. Logistic modelling was carried out and (adjusted Odds Ratio) Ora calculated, adjusted for age, parental educational and characteristics of the school. A negative relationship exists between parental control and substance use, but this relationship is more marked for tobacco (OR a between 1.8 and 5.6 according to level of control, family status and gender) and cannabis (OR between 1.5 and 6.4) than for alcohol (OR a between 1.0 and 2.7). Parental control is more markedly related to substance use in girls than in boys. These tendencies were observed for intact families as well as for single-parent families or reconstituted families. Parental control has a greater impact than emotional support. Among girls, emotional support has a greater impact than among boys. There is a gradient relationship between parental control and current consumption, especially among girls. Thus, there may be a need for parental control, whatever the family structure.

In a traditional Black–Scholes market we develop a verification theorem for a general class of investment and consumption problems where the standard dynamic programming principle does not hold. The theorem is an extension of the standard Hamilton–Jacobi–Bellman equation in the form of a system...... of non-linear differential equations. We derive the optimal investment and consumption strategy for a mean-variance investor without pre-commitment endowed with labor income. In the case of constant risk aversion it turns out that the optimal amount of money to invest in stocks is independent of wealth...... of future labor income net of consumption. Using the verification theorem we give a detailed analysis of this problem. It turns out that the optimal amount of money to invest in stocks is given by a linear function of wealth plus the financial value of future labor income net of consumption. The optimal...

Consistent with the international evidence on investment cycles, we show that business investment in Ireland exhibits large cyclical movements around a long-run trend relative to GDP. Changes in business investment broadly coincide with the overall business cycle, although swings in investment tend to be far greater, with extended periods of both over- and under-investment relative to GDP. The sharp fall in business investment si...

Dimensions of parental overprotection are clarified in a critical review of the research and clinical literature. An indulgent style of parenting is distinguished from an overprotective parent-child relationship. Differential antecedents and outcomes are proposed for each of these forms of parent-child interaction. Measures of protection are reviewed. A new conceptual model of parental overprotection is presented which takes into account child, parent, family, socio-cultural, environmental and resiliency factors. Directions for future research are suggested.
According to evolutionary explanations men hardly ever are absolutely certain about their biological fatherhood therefore they must seek various sources of information to subjectively establish whether they are the genetic fathers of the children they raise. Apicella and Marlowe (2004) showed that fathers who perceived greater similarity between their children and themselves were willing to invest more resources (e.g., time, money, care) in their offspring presumably because the perceived resemblance indicated to the fathers their genetic relatedness with their children. The present study extended the design of Apicella and Marlowe's original study and included both fathers and mothers as participants. Parents were recruited by a female confederate at the airport and at the railway station in Wroclaw (Poland). Multiple regression analyses showed that perceived resemblance predicted parental investment in the child for both men and women. The fact that mothers' declarations of investment in their children also depended on the perceived resemblance factor is not consistent with evolutionary formulations delineated by Apicella and Marlowe (2004; 2007). Future studies must resolve the issue of whether the resemblance-investment relation in fathers results from men relaying on child's resemblance to themselves as an indicator of their own biological paternity, or whether it results from the more parsimonious phenomenon that people in general are attracted more to other people who are similar to them.
This is the second of a series of briefings which discuss the sustainable development issues raised by legal arrangements for the protection of foreign investment. The briefings are based on legal research by IIED and its partners. The goal is to provide accessible but accurate information for human rights, development and environmental organisations working on issues raised by foreign investment in low- and middle-income countries. Briefing 2 explains how investment treaties between states work to protect and promote foreign investment.

Research on adult populations has widely investigated the deep differences that characterize individuals who embrace either conservative or liberal views of the world. More recently, research has started to investigate these differences at very early stages of life. One major goal is to explore how parental political ideology may influence children's characteristics that are known to be associated to different ideological positions. In the present work, we further investigate the relations between parents' ideology and children cognitive processing strategies within the framework of political ideology as motivated social cognition (Jost et al., 2003) and the dual process model of political ideology (Duckitt et al., 2002). Specifically, epistemic (implicit attitudes toward order vs. chaos), existential (negativity and threat bias), and relational needs (conformity measure) were assessed in pre-school children (N = 106; 4–6 years). For each child at least one parent completed both the Social Dominance Orientation (SDO) and the Right Wing Authoritarianism (RWA) measures. Interestingly, results indicated that mothers' and fathers' responses had unique associations with children's socio-cognitive motivations, and different findings emerged in relation to the two facets of parental authoritarianism, namely dominance (i.e., SDO) and submission (i.e., RWA). More specifically, children's existential needs appeared to be more related to mothers' RWA scores, whereas children's epistemic needs appeared to be more related to fathers' SDO. Finally, parents' RWA and SDO scores appeared to have opposite effects on children's relational needs: children's conformity increased at increasing levels of mothers' RWA and decreased at increasing levels of fathers' SDO. Overall, however, results were relatively weak and several links between the responses of parents and their children were not significant, suggesting caution in drawing strong conclusions about the impact of parents

Adolescent girls often perpetrate aggression by gossiping and spreading rumours about others, by attempting to ruin relationships and by manipulating and excluding others. Further, males and females engage in reactive and proactive relational aggression differently. In this study, we examined the individual, peer and parental contextual factors that best explained the use of reactive and proactive relational aggression in girls. Female participants (n = 614; ages 11-18 years) completed questionnaires on aggression, callous-unemotional (CU) traits, delinquency, peer delinquency, gender composition of their peer group, resistance to peer influence and perceived parental overcontrol. Multinomial logistic regression was used to examine the effects of individual, peer- and parent-related variables on the likelihood of being classified as a low aggressor, reactive aggressor or proactive/reactive aggressor. Girls in the combined reactive/proactive aggression group were younger, had greater CU traits, a lower proportion of male peers and greater perception of parental control than both the reactive and low aggressive groups. Both highly aggressive groups were more delinquent and had greater peer delinquency than the low aggressive group. This study suggests those girls who show relational aggression for the purpose of gaining status and revenge feel restrained by their parents and may gravitate toward relationships that support their behaviour.

To field test a parental self-efficacy scale regarding its acceptability and feasibility and to describe parental self-efficacy in a convenience sample of parents with children aged 6 years old or less. Self-care within families is increasingly emphasised in health policy as a means of maximising healthcare resources. This study reports the field testing of a scale designed to measure parental self-efficacy. Cross-sectional survey of parents of children aged 6 years old or less. Subjects were recruited through a parenting internet website (n = 84) and local parenting and community organisations (n = 68) and asked to complete a questionnaire containing the scale. Data collection took place between January and August 2011. The scale, previously validated with an expert panel of professionals, gathered information about parental self-efficacy when administered either directly or through an on-line data collection portal, although there were more missing data when administered via the Internet. Although convenience and self-selecting samples precluded parameter estimation, areas of concern highlighted were difficulties differentiating children with serious illnesses and the use of the Personal Child Health Record. Use of the Internet was widespread, as was use of community pharmacists and nursery staff. Although the primary purpose was not to collect specific data, the data indicated the continuing concern of parents regarding serious illness and where additional investment may be required to meet parental needs and expectations. The previously validated scale can be used to collect information about parental self-efficacy either through a paper questionnaire or the Internet. Although there was slightly more missing data from the Internet version, the ease of its administration makes this an attractive option. Parents generally reported high levels of self-efficacy and satisfaction with services; however, the scale was able to identify areas where further investment

To examine changes in parent-child communication related to sexual behavior after exposure to public health messages. Randomized, controlled trial that was part of precampaign message testing. Exposure occurred online or through DVDs mailed to participants and viewed on their personal computers. Data collection occurred via a secure Web site. Participants included parents (n = 1969) living with a child age 10 to 14 years drawn from a nationally representative sample of U.S. households. Treatment participants were exposed to video, audio, and print advertisements that promoted the benefits of speaking to their children early and often about delaying initiation of sexual activity; messages also directed parents to an informational Web site. The dependent variable assessed frequency of parent-child communication related to sexual behavior. The primary independent variable was treatment assignment. Longitudinal growth modeling that included five waves of data. The trajectory of growth over time differed between fathers in the treatment group and fathers in the control group (F[1, 2357] = 4.15; p groups. This study demonstrates that father-child and mother-child communication patterns differ over time in response to public health messages. Findings have implication for researchers developing health marketing campaigns.

Parental investment theory predicts that maternal resources are finite and allocated among offspring based on factors including maternal age and condition, and offspring sex and parity. Among humans, firstborn children are often considered to have an advantage and receive greater investment than their younger siblings. However, conflicting evidence for this "firstborn advantage" between modern and hunter-gatherer societies raises questions about the evolutionary history of differential parental investment and birth order. In contrast to humans, most non-human primate firstborns belong to young, inexperienced mothers and exhibit higher mortality than laterborns. In this study, we investigated differences in maternal investment and offspring outcomes based on birth order (firstborn vs. later-born) among wild chimpanzees ( Pan troglodyte schweinfurthii ). During the critical first year of life, primiparous mothers nursed, groomed, and played with their infants more than did multiparous mothers. Furthermore, this pattern of increased investment in firstborns appeared to be compensatory, as probability of survival did not differ by birth order. Our study did not find evidence for a firstborn advantage as observed in modern humans but does suggest that unlike many other primates, differences in maternal behavior help afford chimpanzee first-borns an equal chance of survival.
Full Text Available This article shows that it can take a long period of time until research knowledge finds its application in practice and get disseminated as innovation trend. Factor-based investing is such an example. Having its developing roots in the nineties, it took more than two decades until this approach was detected by the by investment community. The goal of this article is to recall the definition of factor investing, present its historical evolvement and motivate its recent break-through and current trend among investment practitioners (known also under the notion smart beta. It aims at familiarizing with this investment approach from a practical perspective and highlighting its diversifying benefits in a portfolio context with the potential to outperform the market on risk-adjusted basis.

Full Text Available Being value based is one of the principles project management has to respect in order to be sustainable. Values are guidelines for human behavior that are shared by a large group of individuals. As projects can be differentiated from investments, also projects’ values can be differentiated from investments’ values. Connecting projects with investments’ values contributes to projects’ success, to a sustainable project management process and to a sustainable investment. The article explains the differences between investments and projects and presents how the investment’s values can be related to the project. The topic is applicable when dealing with projects in general and can have benefic effects on investments initialized through projects financed by the European Union.

This study tests two evolutionary hypotheses on grandparental investments differentiated by the child's sex: the paternity uncertainty hypothesis and the Trivers-Willard hypothesis. Data are from two culturally different countries: the Dutch Longitudinal Aging Study Amsterdam (n=2375) and the Chinese Anhui Survey (n=4026). In the Netherlands, grandparental investments are biased towards daughters' children, which is in accordance with the paternity uncertainty hypothesis. But in China, grandparental investments are biased towards sons' children, which is in conflict with the paternity uncertainty hypothesis. This study found no support for the Trivers-Willard hypothesis. These results raise doubts over the relevance of paternity uncertainty as an explanation of a grandparental investment bias towards daughters' children that is often found in Western populations. The results suggest that discriminative grandparental investments are better understood as the outcome of cultural prescriptions and economic motives.

This study analyzes temperamental and social correlates of 18-month-olds' (N=58) instrumental helping (i.e., handing over out-of-reach objects) and comforting (i.e., alleviating experimenter's distress). While out-of-reach helping as a basic type of prosocial behavior was not associated with any of the social and temperamental variables, comforting was associated with maternal responsible parenting, day care attendance, and temperamental fear, accounting for 34% of the total variance in a corresponding regression model. The data of the present study suggest that, while simple instrumental helping seems to be a robust developmental phenomenon, comforting is associated with specific social experiences and child temperament that constitute interindividual differences and thereby help to explain the domain-specific development of prosociality.

The paper studies retail Socially Responsible Investment and portfolio allocation. It extends conventional portfolio theory by allowing for a personal value based investment decision. When preferences for responsibility enter the framework for mean-variance analysis, it yields an optimal...... responsible investment model. An example of index investing illustrates the theory. Results show that it is crucial for the responsible investor to consider portfolio risk, expected return, and responsibility simultaneously in order to obtain an optimal portfolio. The model enables responsible investors...

The purpose of this paper is to survey what is known about the investment policy of pension funds. Pension fund investment policy depends critically on the type of plan: defined contribution versus defined benefit. For defined contribution plans investment policy is not much different than it is for an individual deciding how to invest the money in an Individual Retirement Account (IRA). The guiding principle is efficient diversification, that is, achieving the maximum expected return for any...
The increase in the distributed generation of electricity, with wind turbines and solar panels, necessitates investments in the distribution network. The current tariff regulation in the Dutch electricity industry, with its ex post evaluation of the efficiency of investments and the frontier shift in the x-factor, delays these investments. In the unbundled electricity industry, the investments in the network need to be coordinated with those in the distributed generation of electricity to enable the DSOs to build enough network capacity. The current Dutch regulations do not provide for a sufficient information exchange between the generators and the system operators to coordinate the investments. This paper analyses these two effects of the Dutch regulation, and suggests improvements to the regulation of the network connection and transportation tariffs to allow for sufficient network capacity and coordination between the investments in the network and in the generation of electricity. These improvements include locally differentiated tariffs that increase with an increasing concentration of distributed generators.
This is the fourth of a series of briefings which discuss the sustainable development issues raised by legal arrangements for the protection of foreign investment. The briefings are based on legal research by IIED and its partners. The goal is to provide accessible but accurate information for human rights, development and environmental organisations working on issues raised by foreign investment in low- and middle-income countries. Briefing 4 sets out some of the ways in which foreign investment contracts can impact on sustainable development.

Most quantitative research on fertility decline in the United States ignores the potential impact of cultural and familial factors. We rely on new complete-count data from the 1880 U.S. census to construct couple-level measures of nativity/ethnicity, religiosity, and kin availability. We include these measures with a comprehensive set of demographic, economic, and contextual variables in Poisson regression models of net marital fertility to assess their relative importance. We construct models with and without area fixed effects to control for unobserved heterogeneity. All else being equal, we find a strong impact of nativity on recent net marital fertility. Fertility differentials among second generation couples relative to the native-born white population of native parentage were in most cases less than half of the differential observed among first generation immigrants, suggesting greater assimilation to native-born American childbearing norms. Our measures of parental religiosity and familial propinquity indicated a more modest impact on marital fertility. Couples who chose biblical names for their children had approximately 3% more children than couples relying on secular names while the presence of a potential mother-in-law in a nearby households was associated with 2% more children. Overall, our results demonstrate the need for more inclusive models of fertility behavior that include cultural and familial covariates.

We introduce the formalism of action investment energy games where we study the trade-off between investments limited by given budgets and resource constrained (energy) behavior of the underlying system. More specifically, we consider energy games extended with costs of enabling actions and fixed...... budgets for each player. We ask the question whether for any Player 2 investment there exists a Player 1 investment such that Player 1 wins the resulting energy game. We study the action investment energy game for energy intervals with both upper and lower bounds, and with a lower bound only, and give...
Numerous institutions are now engaged in Socially Responsible Investment or have signed the "UN Principles for Responsible Investment". Retail investors, however, are still lacking behind. This is peculiar since the sector constitutes key stakeholders in environmental, social and governmental...... standards. This paper considers optimal responsible investment for a small retail investor. It extends conventional portfolio theory by allowing for a personal-value based investment decision. Preferences for responsibility are defined in the framework of mean-variance analysis and an optimal responsible...... investment model identified. Implications of the altered investment problem are investigated when the dynamics between portfolio risk, expected return and responsibility is considered. Relying on the definition of a responsible investor, it is shown how superior investment opportunities can emerge when...

Reports of parenting styles were assessed in 110 primarily white, middle-class sixth, eighth, and tenth graders (M = 11.98, 13.84, and 16.18 years of age) and their parents (108 mothers and 92 fathers). Parents judged the legitimacy of parental authority and rated family conflict and rules regarding 24 hypothetical moral, conventional, personal, multifaceted (containing conventional and personal components), prudential, and friendship issues. Adolescents viewed their parents as more permissive and more authoritarian than parents viewed themselves, whereas parents viewed themselves as more authoritative than did adolescents. Parents' parenting styles differentiated their conceptions of parental authority, but adolescents' perceptions did not. Differences were primarily over the boundaries of adolescents' personal jurisdiction. Furthermore, conceptions of parental authority and parenting styles both contributed significantly to emotional autonomy and adolescent-parent conflict. The implications of the findings for typological models of parenting and distinct domain views of social-cognitive development are discussed.

It's so new firms, as well as the establishment ofinternational operations of the company through expansion of existing operations. Typically, the companyincurred in a market that is confined to a distinct geographical area, but the limits of market changes. Thechange can be the result of higher management decisions on market opening and development of a newtechnology or product. Markets with a lower level of development are likely to attract a higher level of directinvestments than those in more developed countries. The specific reasons behind the decision of a company toinvest abroad are operating efficiency, reduce risk, market development and Government policy in the hostcountry. Transnational corporations are large conglomerates which consists of the parent company and itssubsidiaries/branches, both in the country of residence and abroad. Transnational corporations affect stronglyboth the production and the world of international economic relations. This influence is determined by themotivations of expansion that they promote.

In a traditional Black–Scholes market we develop a verification theorem for a general class of investment and consumption problems where the standard dynamic programming principle does not hold. The theorem is an extension of the standard Hamilton–Jacobi–Bellman equation in the form of a system of non-linear differential equations. We derive the optimal investment and consumption strategy for a mean-variance investor without pre-commitment endowed with labor income. In the case of constant risk aversion it turns out that the optimal amount of money to invest in stocks is independent of wealth. The optimal consumption strategy is given as a deterministic bang-bang strategy. In order to have a more realistic model we allow the risk aversion to be time and state dependent. Of special interest is the case were the risk aversion is inversely proportional to present wealth plus the financial value of future labor income net of consumption. Using the verification theorem we give a detailed analysis of this problem. It turns out that the optimal amount of money to invest in stocks is given by a linear function of wealth plus the financial value of future labor income net of consumption. The optimal consumption strategy is again given as a deterministic bang-bang strategy. We also calculate, for a general time and state dependent risk aversion function, the optimal investment and consumption strategy for a mean-standard deviation investor without pre-commitment. In that case, it turns out that it is optimal to take no risk at all.

Full Text Available BACKGROUND: Parent-of-origin effects have been found to influence the mammalian brain and cognition and have been specifically implicated in the development of human social cognition and theory of mind. The experimental design in this study was developed to detect parent-of-origin effects on theory of mind, as measured by the 'Reading the mind in the eyes' (Eyes task. Eyes scores were also entered into a principal components analysis with measures of empathy, social skills and executive function, in order to determine what aspect of theory of mind Eyes is measuring. METHODOLOGY/PRINCIPAL FINDINGS: Maternal and paternal influences on Eyes scores were compared using correlations between pairs of full (70 pairs, maternal (25 pairs and paternal siblings (15 pairs. Structural equation modelling supported a maternal influence on Eyes scores over the normal range but not low-scoring outliers, and also a sex-specific influence on males acting to decrease male Eyes scores. It was not possible to differentiate between genetic and environmental influences in this particular sample because maternal siblings tended to be raised together while paternal siblings were raised apart. The principal components analysis found Eyes was associated with measures of executive function, principally behavioural inhibition and attention, rather than empathy or social skills. CONCLUSIONS/SIGNIFICANCE: In conclusion, the results suggest a maternal influence on Eye scores in the normal range and a sex-specific influence acting to reduce scores in males. This influence may act via aspects of executive function such as behavioural inhibition and attention. There may be different influences acting to produce the lowest Eyes scores which implies that the heratibility and/or maternal influence on poor theory of mind skills may be qualitatively different to the influence on the normal range.

Full Text Available Theoretical and empirical studies have focused on discretionary investments such as research and development (R&D and advertisement as value-creating activities. This empirical research article examines the determinants of the discretionary investment policy of food sector firms in India. The study aims to analyze the impact of financial policies and firm characteristics on the discretionary investment strategy of the food industry firms. The article uses the partial least squares structural equation modeling (PLS-SEM to understand the drivers of discretionary investment policy of food sector firms. The study finds that investment policy of firms is a major determinant of profitability of food sector firms. Higher investments in capital expenditures and working capital result in higher profitability. Management efficiency significantly influences firm profitability. The results suggest that riskier firms in food sector might focus on R&D investments as a strategy to generate more cash flows. Size of firm is negatively related to R&D intensity. Smaller firms in food sector tend to invest more in R&D. The study does not provide evidence to suggest that profitable firms invest more in R&D activities.

A severe collapse of fixed capital formation distinguished the onset of the Great Depression from other investment downturns between the world wars. Using a model estimated for the years 1890-2000, we show that the expected profitability of capital measured by Tobin's q, and the uncertainty...... surrounding expected profits indicated by share price volatility, were the chief influences on investment levels, and that heightened share price volatility played the dominant role in the crucial investment collapse in 1930. Investment did not simply follow the downward course of income at the onset...

The aim of this study was to investigate the parental willingness to invest in good oral health for their child in terms of money and time and to relate this to oral health related knowledge and behavioral aspects. 290 parents of 6-year-old children, participating in a RCT on caries preventive strategies in The Netherlands were asked to provide information on education, oral health habits, dietary habits, knowledge on dental topics, willingness to pay and perceived resistance against investing in preventive oral health actions for their children. Despite the fact that parents overall valued oral health for their child highly, still 12% of the parents were unwilling to spend any money, nor to invest any time by brushing their children's teeth to maintain good oral health for their child. Additionally, they indicated that they were unwilling to visit the dentist for preventive measures more than once a year. These children may certainly be considered at higher risk of developing oral diseases because worse oral hygiene habits and dietary habits were found in this group. Given the results, it may be necessary to differentiate in allocating caries prevention programmes to target parents or (school-based) children directly. Copyright © 2012 Elsevier Ltd.

Full Text Available I chose this topic because my goal was to capture in detail all aspects of the evolution of investment funds under the influence of factors leading to globalization of the banking financial market. Main motivation was that I proposed to present in an original manner the concept of investment in mutual funds by the thoroughness of the following points: the different types of investment funds from Romania, the advantages, the risks and the specific costs of the investment in mutual funds and the effects of the financial crisis on the industry of the investment funds on the national level. The financial crisis and the risk of infecting the global economy affected the taste of risk of the investors and their request for the investment fund, determining the orientation of the investors to the funds with a lower risk – the diversified funds, the funds of bonds and the monetary funds. I considered important the theoretical approach of the concept of investments in investment funds because they are a barometer of the macro economical stability, in case the economical increase is positive on the macro economical level the investments in investments funds are increasing too. In Romania the market of the mutual funds is at an incipient level, but with potential and perspectives of development. Due to the bankruptcy of FNI in the beginning of the years 2000 and due to the absence of a clear legislation regarding the calculation of the unitary value of the net asset and the control of the activity developed by the investment funds, the development of the industry of the investment funds had to fight against the crisis of credibility generated by these events. The convergence of the Romanian economy to the European standards will attract also a modification of the structure of the financial investments of the individuals, by an increase of the investments in funds. In the world the investment funds are preferred by the investors for their advantages

Full Text Available The actual deficiency of investment into Russian industry innovative development increases its technological drag from industries of countries with developed markets. Although the rate of investment into real sectors of Russian economics mid 2000 was higher compared to the previous period, annual investment amounts were much lower than in 1990. At present, highest investment amounts are directed to industry extractive branches and to the commerce. Amounts invested to various economy branches do not correspond to their contribution to the country’sGross Added Product; particularly underinvested are manufacturing industry branches. At present, foreign share in the country economy total investment makes 15–18%. Recently, most interesting for foreigners was investment to machine-building branches with overwhelming part (for example, 90% in 2007–2008 of foreign investment into the machine-building industry being directed to creation of new automobile plants. Today, first place in the list of foreign investors’ preferences in Russia is taken by the machine-tool construction sector.

Full Text Available We construct a comprehensive measure of overall investment banking competitiveness for follow-on offerings that aggregates the various dimensions of competition such as fees, pricing accuracy, analyst recommendations, distributional abilities, market making prowess, debt offering capabilities, and overall reputation. The measure allows us to incorporate trade-offs that investment banks may use in competing for new or established clients. We find that firms who switch to similar-quality underwriters enjoy more intense competition among investment banks which manifests in lower fees and more optimistic recommendations. Investment banks do compete vigorously for some clients, with the level of competition related to the likelihood of gaining or losing clients. Finally, investment banks not performing up to market norms are more likely to be dropped in the follow-on offering. In contrast, firms who seek a higher reputation underwriter face relatively non-competitive markets.
A study was conducted to assess the effect that different energy options would have on provincial and regional employment prospects in British Columbia. Current and future economic and employment patterns were examined to develop a more detailed understanding of the skills, age, gender, location, and other characteristics of British Columbia workers. Over 40 previous studies examining the energy/employment relationship were also reviewed. Based on this review and an analysis of the province's economic and labor conditions, the following conclusions are drawn. Investment in non-energy sectors offers better prospects for reducing unemployment than investment in the energy sector, whether for new supply or improving efficiency. Investments in the energy sector provide fewer jobs than investments in most other sectors of the economy. Among the available electricity supply options, large hydroelectric projects tend to produce the fewest jobs per investment dollar. Smaller thermal projects such as wood residue plants produce the most jobs. If and when more energy is needed in British Columbia, the most cost-effective combination of energy supply and efficiency options will also create the most jobs. Compared to traditional energy supply options, investments in energy efficiency would create about twice as many total jobs, create jobs that better match the skills of the province's unemployed and its population distribution, and create jobs that last longer on the average. Construction-related measures such as improved insulation tend to produce more jobs per investment dollar than the substitution of more energy-efficient equipment. 69 refs., 9 tabs
Full Text Available In the article the approaches to defining the essence of the concept of “investment attractiveness of enterprises” were analyzed. On the example of "Agrofirm Brusilov" depth analysis of the agricultural enterprises to evaluate of profitability, liquidity, solvency, financial stability, the timing of the return of invested funds and minimizing investment risks was conducted. To study methods of rating and system analysis were used. To justify the conditions of increasing investment attractiveness farms method of scoring was used. It was established as a result of the use of integrated evaluation of the financial position one can see problem aspects of financial position of the company and develop measures to enhance liquidity, solvency, identify potential for raising the efficiency of company and prevention of financial crisis. The analysis of financial position showed that the management of the enterprise doesn’t think about financial stability and solvency, does not understand the benefit of borrowed capital. Using research results in practice of agricultural enterprises allows us to give a real evaluation of investment attractiveness and justify ways to improve it. Key words: investments, investment attractiveness, potential business, financial position.

This study examined the direct and buffering effects of social support on longer-term global psychological distress among parents coping with pediatric cancer. In both sets of analyses, we examined whether these effects depended on the dimension of social support provided (i.e., satisfaction with support versus size of support network). Participants were 102 parents of pediatric cancer patients. At study entry, parents reported their trait anxiety, depression, and two dimensions of their social support network (satisfaction with support and size of support network). Parents subsequently reported their psychological distress in 3- and 9-month follow-up assessments. Parents' satisfaction with support had a direct effect on longer-term psychological distress; satisfaction was negatively associated with distress at both follow-ups. In contrast, size of support network buffered (moderated) the impact of trait anxiety and depression on later distress. Parents with smaller support networks and higher levels of trait anxiety and depression at baseline had higher levels of psychological distress at both follow-ups; for parents with larger support networks, there was no relationship. Social support can attenuate psychological distress in parents coping with pediatric cancer; however, the nature of the effect depends on the dimension of support. Whereas interventions that focus on increasing satisfaction with social support may benefit all parents, at-risk parents will likely benefit from interventions that ensure they have an adequate number of support resources.

Non-malleability of capital is incorporated in the model through an asymmetric cost......-function of investment, and investments can be both positive and negative. Exploitation is controlled through the utilisation rate of available capital. A novel feature in this model is that there are costs associated with the available capital whether it is utilised or not. And, in contrast to most of the previous...

As with any technological innovation, time refines the technology, improving upon the original version of the innovative product. The initial GM crops had single traits for either herbicide tolerance or insect resistance. Current varieties have both of these traits stacked together and in many cases other abiotic and biotic traits have also been stacked. This innovation requires investment. While this is relatively straight forward, certain conditions need to exist such that investments can be facilitated. The principle requirement for investment is that regulatory frameworks render consistent and timely decisions. If the certainty of regulatory outcomes weakens, the potential for changes in investment patterns increases. This article provides a summary background to the leading plant breeding technologies that are either currently being used to develop new crop varieties or are in the pipeline to be applied to plant breeding within the next few years. Challenges for existing regulatory systems are highlighted. Utilizing an option value approach from investment literature, an assessment of uncertainty regarding the regulatory approval for these varying techniques is undertaken. This research highlights which technology development options have the greatest degree of uncertainty and hence, which ones might be expected to see an investment decline. PMID:24499745

Parents who use drugs parent in a context of heightened concern regarding the damaging effects of parental drug use on child welfare and family life. Yet there is little research exploring how parents who use drugs account for such damage and its limitation. We draw here upon analyses of audio......-recorded depth qualitative interviews, conducted in south-east England between 2008 and 2009, with 29 parents who use drugs. Our approach to thematic analysis treated accounts as co-produced and socially situated. An over-arching theme of accounts was 'damage limitation'. Most damage limitation work centred...... on efforts to create a sense of normalcy of family life, involving keeping drug use secret from children, and investing heavily in strategies to maintain ambiguity regarding children's awareness. Our analysis highlights that damage limitation strategies double-up in accounts as resources of child protection...
Rivers provide society with numerous returns. These relate to both the passive and extractive uses of the resources embodied in river environments. Some returns are manifest in the form of financial gains whilst others are non-monetary. For instance, rivers are a source of monetary income for those who harvest their fish. The water flowing in rivers is extracted for drinking and to water crops and livestock that in turn yield monetary profits. However, rivers are also the source of non-monetary values arising from biological diversity. People who use them for recreation (picnicking, swimming, boating) also receive non-monetary returns. The use of rivers to yield these returns has had negative consequences. With extraction for financial return has come diminished water quantity and quality. The result has been a diminished capacity of rivers to yield (non-extractive) environmental returns and to continue to provide extractive values. A river is like any other asset. With use, the value of an asset depreciates because its productivity declines. In order to maintain the productive capacity of their assets, managers put aside from their profits depreciation reserves that can be invested in the repair or replacement of those assets. Society now faces a situation in which its river assets have depreciated in terms of their capacity to provide monetary and non-monetary returns. An investment in river "repair" is required. But, investment means that society gives up something now in order to achieve some benefit in the future. Society thus has to grapple wih the choice between investing in river health and other investments--such as in hospitals, schools, defence etc. - as well as between investing in river health and current consumption--such as on clothes, food, cars etc. A commonly used aid for investment decision making in the public sector is benefit cost analysis. However, its usefulness in tackling the river investment problem is restricted because it requires all

In previous studies by our group, we found that female offspring of parental divorce and parental remarriage are more susceptible to suicide attempt than male offspring. In this study, we examine whether these findings remain even after controlling for offspring depression. The sample consists of respondents from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions. Multivariable regressions controlled for offspring depression, parental depression, age, race/ethnicity, income, and marital status. Our previous findings that female offspring of parental divorce and parental remarriage are more likely to report a lifetime suicide attempt than male offspring remained even after controlling for offspring depression.

Its primary manifestation is the child’s campaign of denigration against a parent, a campaign that has no justification. It is said to result from a combination of a programming (brainwashing parent’s indoctrinations and the child’s own contributions to the vilification of the targeted parent. Many evaluators use the term parental alienation syndrome to refer to the disorder engendered in such children. However, there is significant controversy going on about the validity of parental alienation syndrome. The purpose of this article has been to describe and help to differentiate parental alienation syndrome and abuse for mental health professionals working in the field, and discuss the arguments about the validity of this syndrome.
This thesis analyzes different aspects of the investment decision. In the first chapter, we consider an economy in which different energy sources may produce electricity. The model focuses first on the optimal use of a hydroelectric dam from which water can be extracted and which is supplied with a random water flow. The presence of constraints on a minimal and on a maximal storage capacity makes electricity consumption smoothing possible only when the quantity of water available to the agent lies in a certain range that we determine. In a second stage, we introduce a second energy source with unlimited supply at some exogenous cost. The marginal propensity to produce hydroelectricity is an increasing function of the second technology cost. The availability at a low cost of the alternative source improves thus time diversification. Finally, the optimal electric park is composed of a number of dams that is increasing with the cost of the second technology. Chapter 2 studies the decision of an investor who wants to undertake an irreversible investment when he has the choice between two mutually exclusive projects that present input price and/or output price uncertainty. We prove that the investor decides not to invest in any project when each investment generates the same payoff independently of its size. Therefore, some inaction region appears in which the investor prefers not to invest whereas an immediate investment would have been optimal if no choice had been available: a 'choice value' is thus created. A key feature of this bidimensional degree of uncertainty is thus that the payoff generated by each project is not a sufficient statistic to make a rational investment. In this context, our analysis provides a new motive for waiting to invest: the benefits associated with the dominance of one project over the other. In chapter 3, we study the investment decision problem of a duo-poly with price competition on a market of finite size driven by stochastic taste

We present a model of investment under uncertainty about fundamentals, using a global games approach. Goldstein & Razin (2003) show that there is an information based trade-off between foreign direct investment (FDI) and portfolio investment (PI) which rationalizes some well known stylised facts in the literature - the relative volatility and reversibility of foreign direct investment versus portfolio investment. We extend their result and show that uncertainty about fundamentals does not imp...

We estimate a New-Neoclassical Synthesis model of the business cycle with two investment shocks. The first, an investment-specific technology shock, affects the transformation of consumption into investment goods and is identified with the relative price of investment. The second shock affects the production of installed capital from investment goods or, more broadly, the transformation of savings into future capital input. We find that this shock is the most important driver of U.S. business...
This study analyses the relationship between firms’ foreign and domestic investments using a panel dataset containing 218 Finnish manufacturing firms during the years 1998-2002.

A multi-dimensional, non-linear dynamic model in continuous time is presented for the purpose of finding the optimal combination of exploitation and capital investment in optimal renewable resource management. Non-malleability of capital is incorporated in the model through an asymmetric cost......-function of investment, and investments can be both positive and negative. Exploitation is controlled through the utilisation rate of available capital. A novel feature in this model is that there are costs associated with the available capital whether it is utilised or not. And, in contrast to most of the previous...... literature, the state variables, namely the physical capital and the biological resource, enter the objective function. Due to the nonlinearities in this model some of the results are in sharp contrast to previous literature....

Is there a link between the stock market and business investment? Empirical evidence indicates that there is. A firm tends to invest more when its stock price increases, and it tends to invest less when the price falls. In “Stock Prices and Business Investment,” Yaron Leitner discusses existing research that explains this relationship. One question under consideration is whether the stock market actually improves investment decisions.
The investment decision is part of a companies’ investment strategy. Defined as a logical set of technical and economic information, the investment strategy determines the main objectives of the firm regarding its investments, based on studies, analysis and simulations. It also establishes the actions to be undertaken in order to achieve the objectives, methods of achieving them, sources of funding and resource allocation methods. Still, all these are influenced by several factors. The invest...

While a parental perception of child vulnerability to illness/injury is often used interchangeably with parental overprotection, research suggests that these constructs are independent. Distinct parental psychological characteristics were hypothesized for each construct. The parents of 871 children, ages 22-72 months, completed a four-part protocol (clinical background data, Child Vulnerability Scale, Parent Protection Scale, and Brief Symptom Inventory). A distinct parent symptom profile was found for perceived child vulnerability (somatization, obsessive-compulsiveness, and anxiety). Overprotection was associated with phobic anxiety, psychoticism, and paranoid ideation. These findings provide further support for the differentiation of these constructs.

In stochastic finance, one traditionally considers the return as a competitive measure of an asset, i.e., the profit generated by that asset after some fixed time span Δt, say one week or one year. This measures how well (or how bad) the asset performs over that given period of time. It has been established that the distribution of returns exhibits ``fat tails'' indicating that large returns occur more frequently than what is expected from standard Gaussian stochastic processes [1-3]. Instead of estimating this ``fat tail'' distribution of returns, we propose here an alternative approach, which is outlined by addressing the following question: What is the smallest time interval needed for an asset to cross a fixed return level of say 10%? For a particular asset, we refer to this time as the investment horizon and the corresponding distribution as the investment horizon distribution. This latter distribution complements that of returns and provides new and possibly crucial information for portfolio design and risk-management, as well as for pricing of more exotic options. By considering historical financial data, exemplified by the Dow Jones Industrial Average, we obtain a novel set of probability distributions for the investment horizons which can be used to estimate the optimal investment horizon for a stock or a future contract.

Full Text Available In this paper, a dynamic inflation-protected investment strategy is presented, which is based on traditional asset classes and Markov-switching models. Different stock market, as well as inflation regimes are identified, and within those regimes, the inflation hedging potential of stocks, bonds, real estate, commodities and gold are investigated. Within each regime, we determine optimal investment portfolios driven by the investment idea of protection from losses due to changing inflation if inflation is rising or high, but decoupling the performance from inflation if inflation is low. The results clearly indicate that these asset classes behave differently in different stock market and inflation regimes. Whereas in the long-run, we agree with the general opinion in the literature that stocks and bonds are a suitable hedge against inflation, we observe for short time horizons that the hedging potential of each asset class, especially of real estate and commodities, depend strongly on the state of the current market environment. Thus, our approach provides a possible explanation for different statements in the literature regarding the inflation hedging properties of these asset classes. A dynamic inflation-protected investment strategy is developed, which combines inflation protection and upside potential. This strategy outperforms standard buy-and-hold strategies, as well as the well-known 1 N -portfolio.

Full Text Available The article is devoted to the variable and disproportionate funding of science in the Russian economy. The paper is focused on the analysis of the Russian financial flows into scientific research and development. The paper explains the dynamics of the main investment flows trends into research and development, highlights the causes of financial flows variable dynamics directed to the high-tech industry. In the work, the investment situation in the Russian market was compared with the foreign experience. The genesis of the optimal financial distribution problems showed the need to develop a dynamic model with the built-in differential equations to forecast the behavioral dynamics of investment flows. We selected the statistical indicators, which have a significant impact on the dynamics of investment flows directed into science. To assess the dynamics of investment flows, we have developed a methodology, which provides a cumulative assessment of the territory investment attractiveness. The multifactor integral estimation allows to describe a data array, reflecting the accumulation of investment attractiveness over time depending on the dynamics of the resultant socio-economic proportional indexes. Due to the accumulation of a data array over time using a differential equation, it is possible to obtain a forecast of the volume of the territory investment attractiveness. The amount of the projected investment flows depends directly on the amount of the investment attractiveness accumulated for the previous step of model’s time. The integrated assessment of the investment attractiveness of the scientific sector in the region allows to reveal the investors preference of the regions with a high concentration of research institutions and higher education institutes.

Full Text Available The article studies investment strategy and efficiency of investment activity of European insurance companies. In particular, it analyses the share of investments of insurance companies of Europe in GDP, investment portfolio of European insurers and its structure, contribution of insurance companies – leaders of investment activity – into the European investment portfolio. It studies influence of the financial crisis upon investment strategy of European insurers and analyses efficiency of investment activity of European insurers in risk insurance and life insurance. The article proves that investment business models of insurance companies are capable of resisting crisis phenomena more efficiently than other financial institutions. It marks out that measures of insurance companies that are directed at increase of profitability of investments require from them both significant expenditures on creation of the system of investment risk management and open access to different categories of financial assets and markets, which influences the general risk level, taken upon by an insurance company. The author draws a conclusion that, taking into account recent developments, European insurers should focus on equity and investment risk management, finding new possibilities for their (investments growth and also adaptation of new systems and operations for solution of these important tasks.

Full Text Available In this paper we have synthesized a part of legislative and conceptual elements linked to a new model of investors which is increasingly publicized in Romania, business angels. In the first part of the paper we have presented theoretical notions related to the concept of investments and to the importance of the investment decision at managerial level. Modern investments regarding, in particular, the launch of some products and services as well as the start-up of companies are dependent on the source of funding that can take many forms, one of them being that of business angels. Thus, the legislative framework in Romania represents an opportunity not only for those looking for sources of financing but also for investors seeking more flexible and more advantageous ways to place capital. Thus, at the end of the paper we have tried to reveal the main fiscal facilities from EU member countries in order to be studied by any business angel and the most important organizations offering information on the business angels’ portfolio.

This paper summarizes the content of Capgemini's 10. European Energy Markets Observatory (EEMO) report. The EEMO is an annual report that tracks the progress in establishing an open and competitive electricity and gas market in the 27 European countries, including Norway and Switzerland. This tenth edition is based on 2007 and winter 2007-2008 data sets. A 1 trillion euros infrastructure investment is required to build the plants, electrical lines and gas pipelines needed in Europe over the next 25 years. Although today's credit crunch could severely hurt the investment cycle, analysts also anticipate a difficult period for the European energy markets once the recession is over. The report said that Europe has yet to solve the related issues of responding to its energy demand, while curbing its carbon dioxide (CO 2 ) emissions. In 2007, even at a slower pace than previous years, analysts said European electricity consumption still increased by 0.9% and CO 2 emissions stabilized, instead of decreasing. Despite the mild weather, the electricity security of supply deteriorated, analysts said. The Union for the Coordination of Transmission of Electricity (UCTE) real margin - which takes into account non-usable and unavailable generation capacities - dropped from 7.6% in 2006 to 5.3% in 2007. Analysts said without a significant and vigorous investment program in electricity and gas infrastructures, Europe's energy supply security will be threatened. Since the low point in 2005, utilities started to invest again, but have made energy mix choices that are not moving toward a reduction in CO 2 emissions as the majority (58%) of the planned generation capacities will be fossil-fueled. In 2007, investments in renewable capacities grew fast, wind being the industry's preference, with an addition of 8.3 gigawatt (GW) renewables in Europe. However, analysts said this type of 'non-scheduable' source is not always available during peak hours. This partially explains the security

Professor Summer's article on government spending for education in Pakistan is agreed with. This commentary also suggested that the conference should have included the Ministry of Finance so that there could be multisector agreement that there must be reallocation of public expenditure from the military for future investment in power plants and primary and secondary education systems. The goal would be to eliminate the gender gap in education and to invest in girls' education. Professor Summers argued that inadequate demand needed to be increased with an increased supply of schools. Gender bias was also evident worldwide in missing girls and higher female mortality. Pakistan has the highest sex ratio, which may not reflect a changes in practices among younger mothers. It was argued by Professor Summers that breaking the vicious cycle of high fertility, little or no education, low productivity, and higher mortality among women can be accomplished virtuously by increasing girl's educational levels. The investment in girls will be reaped in the home, marketplace, and in child welfare through changes in household behavior. Educating girls was considered more cost effective than investing in family planning programs. Additional suggestions are provided that improvement in quality of schooling is also important in improving the education of mothers and children and is interactive with mother's education and years of schooling of children. It is likely that if mothers are educated investment returns are greater when quality if enhanced. It would also hold true that investments in health care or in family planning would reap greater returns if mothers are educated. The figures for return on investment are given as over 20% with a doubling of resources over 3.5 years. Returns would be lower if quality is low or jobs are of low quality or if the returns do not appear for another generation. If returns are too low, the question is how this will affect political will. This

Population investment is a major topic in the studies of population and economic relations. In this particular area, numerous theoretical and practical problems are still in need of solution. Concerning the problem of population concept, there are three different approaches: (1) to determine the definition of population investment from the relationship between the population growth and the capital from national income used for investment, including investment in the newly increased population and investment in the entire population; (2) to explain population investment from the economic viewpoint that people are producers; and (3) to explain population investment from the expense needed to change a simple labor force to a skillful labor force. The expenses include educational costs, maintanance spending, wages needed to compensate workers in labor, costs for workers to master and learn modern scientific techniques to be used for production, and the costs of keeping a young labor force in the next generation.

Full Text Available Investment professionals, particularly financial analysts or security analysts evaluate securities and try to determine characteristics of securities and to identify mispriced securities. For that purpose they use different models to estimate the intrinsic value of the common stocks. Traditional valuation models based on the present value of future cash flows are affected by estimated growth rate of the variable used and by the investor’s required rate of return. These models can be used for valuing fixed income securities, such as bonds and preferred stocks. However, in valuing companies with significant growth opportunities they have to expand traditional analysis with option valuation.

The authors reflect on the article in this issue entitled "Borrow or Serve? An Economic Analysis of Options for Financing a Medical School Education" by Marcu and colleagues, which makes a compelling case that a medical school education is a good investment, no matter what financing option students use, from federal service programs to federal loans. The lead author of this Commentary shares lessons learned from his own medical school education, which was funded by an Armed Forces Health Professions Scholarship, and from his current position interacting with medical students across the United States.Regardless of the financing path they choose, all students should understand basic financial concepts and the details of the various pathways that are available to pay for their medical school education, as well as how each could potentially impact their own future and that of their families. One underappreciated aspect of financing a medical school education is that federal repayment scenarios can link loan payments to income, rather than debt levels, which means that all physicians are able to afford their loan payments no matter what specialty they practice, what they are paid, or where they live.Medical education, while expensive, remains the good investment. An MD degree can lead to a lifetime of personal fulfillment and societal contributions. Everyone, with rare exceptions, accepted to a U.S. medical school will be able to finance their medical education via a path that aligns with their personal values and priorities.
Full Text Available Offshore investment funds are alleged to have engaged in trading behavior that is different from their onshore counterparts because they may be subject to less supervision and regulation. In particular, they may trade more intensely. They could also pursue more aggressively certain trading strategies such as positive feedback trading or herding that could contribute to a greater volatility in the market. Using a unique data set, this chapter compares the trading behavior in the Korean stock market between offshore investment funds with their onshore counterparts registered in the US and UK. There are a number of interesting findings. First, there is indeed evidence suggesting that the offshore funds trade more intensely than their onshore counterparts. Second, however, there is no evidence that the offshore funds engage in positive feedback trading. In contrast, there is strong evidence that the funds from the U.S. and U.K. do. Third, while offshore funds do herd, they do so far less than onshore funds in the U.S. or UK. Fourth, offshore funds hold less glamour stocks (e.g. stocks with high P/E in their portfolio than funds in the U.S. or U.K. do. Moreover, flight to glamour stocks during the in-crisis period is less evident in the case of offshore funds. In sum, offshore funds are no especially worrisome monsters.

Full Text Available This study is a multivariate analysis of commodities and stock investment in a newly established market scenario. Return distribution asymmetry is examined with higher order movements. Skewness in commodity future’s return is largely insignificant, whereas kurtosis is highly significant for both stock and commodity future contracts. Correlation analysis is done with Pearson’s and Kendall’s tau measures. Commodities provide significant diversification benefits when added in a portfolio of stocks. Compared with stocks, commodity future’s returns show stronger correlation with unexpected inflation. The volatility is measured through Glosten-Jagannathan-Runkle - Generalized Autoregressive Conditional Heteroskedasticity (GJR-GARCH model and reflects that commodities have inverted asymmetric behavior, that is, more impact from the upward shocks compared with downward. Stocks have asymmetric volatility, that is, more impact from negative shocks compared with positive. Gold has highest inverted asymmetric volatility. Tail dependence, measured through Student’s t copula, shows no combined downside movement. In conclusion, commodity investments provide diversification and inflation protection.
Full Text Available Sustainable economic development has become an important area of concern due to climatic change with its long term effects. Climatic change has posed several challenges for economic sustainability of economies. Now major development projects have to comply with international environmental norms. Failure to do so may result in the delay of a project, fines including penalties for environmental damage or charges for remedial action, that affect the viability of a project or the value of any security taken. This paper investigates with help of secondary date using descriptive statistical technique opportunities and challenges of green investment. Here it is developed into suitable model for developing economies for successfully adopting green investment without much cost to their economies. The paper concludes that green investment involving direct investment and portfolio investment in firms adopting and following environmental protection norms will lead to sustainable growth and investment for economy.

Full Text Available Direct foreign investment is one of the most important economic variables in the world. Aspects related to international investment agreements are reaching an outstanding place in economic international diplomacy. Nowadays, in the multilateral level there is not an agreement regarding investment and therefore this study is focused on this particular type of agreement. In order to reach this objective this study shows, first of all, how different attempts have been developed to get a multicultural a agreement regarding investment, and to refuse the general opinion that says that exponential growth of foreign investment flows in recent years has given impulse to launch a multilateral investment agreement. Secondly, this study discusses about regulations related to foreign investment under current WTO regulations, such as investment, measure agreements, and service agreement. Then, it analyzes what has happened inside the WTO from the creation of the investment team at the Singapore Conference to the failed Conference in Cancun. Finally, it analyzes the main arguments against the multilateral agreement and the effects of future possible multilateral negotiations in investment and it ends with some recommendations and conclusions.

Full Text Available This article takes an anthropological approach to examine how laws governing family formation in Spain affect same-sex couples seeking to become parents, in particular the cultural causes and implications of such laws. It highlights how the same laws are has a different impact on gay couples and lesbian couples. Legislation combines with other factors to favour and expand the possibilities of accessing motherhood for women in lesbian couples while limiting the possibilities of parenthood for men in gay couples. Moreover, the persistence of certain cultural models of fatherhood and motherhood can be observed, which further constrain parenthood access options and the forming of new family models.

This article examines the extent to which investing in safety during the creation of a new chemical installation proves profitable. The authors propose a management supporting cost-benefit model that identifies and evaluates investments in safety within a chemical company. This innovative model differentiates between serious accidents and less serious accidents, thus providing an authentic image of prevention-related costs and benefits. In classic cost-benefit analyses, which do not make such differentiations, only a rudimentary image of potential profitability resulting from investments in safety is obtained. The resulting management conclusions that can be drawn from such classical analyses are of a very limited nature. The proposed model, however, is applied to a real case study and the proposed investments in safety at an appointed chemical installation are weighed against the estimated hypothetical benefits resulting from the preventive measures to be installed at the installation. In the case-study carried out in question, it would appear that the proposed prevention investments are justified. Such an economic exercise may be very important to chemical corporations trying to (further) improve their safety investments.

The power consumption in the common Nordic power market continues to grow. All potential production technologies entail more or less reduction in quality of the environment. This gives each of the Nordic countries incentives to limit the development of capacity and base themselves increasingly on import, which means that other countries take the political burden with the environmental issues (''free rider problem''). The uncertainty about the climate problem may make it rational to postpone investments which are expensive to reverse, like gas power. If the decisions are delayed too long, however, considerable socio-economic costs may accumulate because the price of electricity becomes too high. The present regulations of the environmental concerns in connection with the granting of concession are expensive and unpredictable and put society unnecessarily to expense

In addition to well-established working principles based on conservative and capital preservation oriented investments that ensure it a sustainable future, the CERN Pension Fund recently introduced a new criterion for selecting the numerous opportunities that the market offers: philanthropy. Its first initiative, which also involves the Staff Association’s Long-Term Collection, will help support two orphanages in China. The two charities are located near Beijing. Beijing’s “China Children Charity and Foundation” is an orphanage that cares for up to 80 babies who need surgery to correct birth defects. The other, “Hope Healing Home”, is an organization that deals with 300 babies and cares for sick and physically disabled babies who have been abandoned. All these babies are awaiting treatment and a medical solution. The CERN Pension Fund has over 6700 members. To ensure the greatest efficiency and profitability, the Fund’s por...

Geologically speaking, Colombia is a very attractive country for the world oil community. According to this philosophy new and important steps are being taken to reinforce the oil sector: Expansion of the exploratory frontier by including a larger number of sedimentary areas, and the adoption of innovative contracting instruments. Colombia has to offer, Greater economic incentives for the exploration of new areas to expand the exploratory frontier, stimulation of exploration in areas with prospectivity for small fields. Companies may offer Ecopetrol a participation in production over and above royalties, without it's participating in the investments and costs of these fields, more favorable conditions for natural gas seeking projects, in comparison with those governing the terms for oil

Do parents invest more in higher quality children, or do they compensate for lower quality by giving more to children with lower endowments? We answer this question in the context of a large-scale iodine supplementation programme in Tanzania. We find that children with higher programme exposure were more likely to receive necessary vaccines and were breastfed for longer. Siblings of treated children were also more likely to be immunised. Fertility behavior and investments at the time of birth were unaffected. PMID:27601732

In Keynes' General Theory, investment determines effective demand, which determines unemployment and the labour market plays a negligible role. In New Keynesian models, labour market institutions determine the natural rate of unemployment and the speed at which unemployment adjusts to it. Investment is mostly ignored as a key variable behind the problem of high unemployment, despite a strong empirical association between investment and unemployment. We discuss the evolution of the 'Keynesian'...

This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset and find that green investment has become a key driver of the energy sector and that its rapid growth is now mostly driven by China. Our econometric results suggest that green investment is boosted by economic growth, a sound financial system conducive to low interest rates, and high fuel prices. We also find that some policy interventions, such as the introduction of carbon pricing schemes or “feed-in-tariffs,” which require use of “green” energy, have a positive and significant impact on green investment. Other interventions, such as biofuel support, do not appear to be associated with higher green investment. - Highlights: • We offer a definition of green investment and review its trend since 2000. • We analyze its determinants from both theoretical and empirical perspectives. • Green investment is boosted by economic growth, interest rates, and fuel prices. • Feed-in-tariffs and carbon pricing schemes impact positively green investment

This paper investigates the relation between aggregate investment and oil volatility and its permanent and transitory components for a developing country, Malaysia. In the paper, the components generalized autoregressive conditional heteroskedasticity (CGARCH) model is utilized to decompose conditional oil volatility into permanent oil volatility and transitory oil volatility. Respectively reflecting fundamental-driven and random shifts in oil volatility, they are expected to exert differential effects on aggregate investment. Adopting a vector autoregression (VAR) framework to allow feedback effects between aggregate investment and its determinants, the paper documents evidence supporting the adverse effects of conditional oil volatility, permanent oil volatility and transitory oil volatility on aggregate investment and real output. Interestingly, contrary to the findings for the developed markets (US and OECD), the real effects of permanent oil volatility tend to be stronger. These findings are reasonably robust to variable specification and measurements in the VAR system. Hence, there is an indication that heightened oil volatility accounts for the slumps in Malaysia's aggregate investment after the Asian financial crisis. - Highlights: • Examines the role of oil volatility in Malaysia's aggregate investment. • Makes distinction between permanent and temporary volatility using CGARCH. • Both volatility components depress investment. • Permanent volatility has larger adverse effects. • Results are robust to alternative model specifications

The purpose of this study was to compare the histogram analysis and visual scores in 3T MRI assessment of middle cerebral arterial wall enhancement in patients with acute stroke, for the differentiation of parent artery disease (PAD) from small artery disease (SAD). Among the 82 consecutive patients in a tertiary hospital for one year, 25 patients with acute infarcts in middle cerebral artery (MCA) territory were included in this study including 15 patients with PAD and 10 patients with SAD. Three-dimensional contrast-enhanced T1-weighted turbo spin echo MR images with black-blood preparation at 3T were analyzed both qualitatively and quantitatively. The degree of MCA stenosis, and visual and histogram assessments on MCA wall enhancement were evaluated. A statistical analysis was performed to compare diagnostic accuracy between qualitative and quantitative metrics. The degree of stenosis, visual enhancement score, geometric mean (GM), and the 90th percentile (90P) value from the histogram analysis were significantly higher in PAD than in SAD (p = 0.006 for stenosis, < 0.001 for others). The receiver operating characteristic curve area of GM and 90P were 1 (95% confidence interval [CI], 0.86-1.00). A histogram analysis of a relevant arterial wall enhancement allows differentiation between PAD and SAD in patients with acute stroke within the MCA territory

The International Transmission Company (ITC) is an independent power transmission company that owns, operates and maintains the high voltage transmission system in southeastern Michigan. The company's current focus is on investing in the transmission infrastructure to improve reliability, relieve congestion, improve access to generation and reduce energy costs for consumers. There is a need for investment in power transmission. Trends indicate that power transactions are on the rise while transmission investment is lagging because pricing protocols are inadequate and there is no regional tariff mechanism to allocate the benefits of new investment. The presentation reviewed the applicability of FTRs to transmission owners and the pitfalls of participant funding pricing. It also outlined the regional benefit allocation mechanism (RBAM) with an illustrative example. It was concluded that existing pricing policies must be improved to address the growing need for transmission investment. RBAM is needed to help investors recover costs from project beneficiaries. figs.

Full Text Available China’s investments in the European Union are much lower than what you may expect given the economic size of both entities. These relatively low investments in Europe are a combination of priority and obstacles. The priority for investments is clearly in Asia, Africa and Latin America. This regional pattern is heavily influenced by the need to solve the resource shortage in the medium and long term. The investments in Europe and the United States are mostly market seeking investments. Research specifically focused on Chinese M&A abroad comes to the same conclusion. The success rate of Chinese M&A abroad is much lower than what we see with respect to American or European investments abroad. In this paper, we examine why Chinese firms are facing more difficulties in the European Union than in other regions. The paper focuses on Chinese M&A as proxy for total foreign direct investments abroad. By looking at the factors that have been documented as influencing the level of M&A abroad, it becomes clear that Chinese firms in Europe are hindered by many factors. For example, the trade between China and the EU is relatively low, the institutional quality is lower compared to the United States, there is less experience with respect to Europe and relatively many deals relate to State Owned Enterprises (SOE which makes the deal sensitive. So it is logical that Chinese investments are not very high in Europe. However, the research makes clear that the obstacles for Chinese investments in Europe are disappearing step by step. In that sense, we expect a strong increase of Chinese investments in Europe in the future.
Full Text Available This paper examines the effect of South Africa’s economic fundamentals on net direct investment and net portfolio investment. The results suggest that the main determinants of investment in South Africa are resource prices, input productivity and the economic performance of the domestic economy. The results illustrate that net direct investment and net portfolio investment are close but not perfect substitutes. In addition, we find that an increase in labour input costs reduces both net direct investment and net portfolio investment. Further, an increase in fixed capital productivity increases net direct investment. Further, also the results illustrate that subsidies increase both net direct investment and net portfolio investment. Moreover, an increase in exports increases both net direct investment and net portfolio investment. Policy recommendations are thus proposed that may increase foreign direct investment in South Africa.

Understanding the factors that contribute to behavioral traits is a complex task, and partitioning variance into latent genetic and environmental components is a useful beginning, but it should not also be the end. Many constructs are influenced by their contextual milieu, and accounting for background effects (such as gene-environment correlation) is necessary to avoid bias. This study introduces a method for examining the interplay between traits, in a longitudinal design using differential items in sibling pairs. The model is validated via simulation and power analysis, and we conclude with an application to paternal praise and ADHD symptoms in a twin sample. The model can help identify what type of genetic and environmental interplay may contribute to the dynamic relationship between traits using a cross-lagged panel framework. Overall, it presents a way to estimate and explicate the developmental interplay between a set of traits, free from many common sources of bias.

Covenant renegotiation at investment reduces the agency cost of debt because...... it induces a firm value maximizing investment financing policy and mitigates the overinvestment problem. Incorporating renegotiation outside corporate distress is crucial to explain empirical occurrence patterns of debt renegotiation, the impact of debt renegotiation on corporate securities, and the relation...

By probing the processes of exclusion of transsexuals from the political sphere, this article offers contributions to social and political theory through an examination of the processes of exclusion from the category "human." This article considers how the erasure of investment in their own embodied sex constructs a platform from which to blame others for sex/gender variance, as well as to justify that blaming. Bringing together Giorgio Agamben, Georges Bataille, Judith Butler, and Nikolas Rose with transphobia, medicalization in psychiatry, law, and ethopolitics, this article questions whose investment in sexed embodiment counts and why that investment might be seen as "crazy."

Full Text Available A hallmark of imprinted genes in mammals is the occurrence of parent-of-origin-dependent asymmetry of DNA cytosine methylation (5mC of alleles at CpG islands (CGIs in their promoter regions. This 5mCpG asymmetry between the parental alleles creates allele-specific imprinted differentially methylated regions (iDMRs. iDMRs are often coupled to the transcriptional repression of the methylated allele and the activation of the unmethylated allele in a tissue-specific, developmental-stage-specific and/or isoform-specific fashion. iDMRs function as regulatory platforms, built through the recruitment of chemical modifications to histones to achieve differential, parent-of-origin-dependent chromatin segmentation states. Here, we used a comparative computational data mining approach to identify 125 novel constitutive candidate iDMRs that integrate the maximal number of allele-specific methylation region records overlapping CGIs in human methylomes. Twenty-nine candidate iDMRs display gametic 5mCpG asymmetry, and another 96 are candidate secondary iDMRs. We established the maternal origin of the 5mCpG imprints of one gametic (PARD6G-AS1 and one secondary (GCSAML iDMRs. We also found a constitutively hemimethylated, nonimprinted domain at the PWWP2AP1 promoter CGI with oocyte-derived methylation asymmetry. Given that the 5mCpG level at the iDMRs is not a sufficient criterion to predict active or silent locus states and that iDMRs can regulate genes from a distance of more than 1 Mb, we used RNA-Seq experiments from the Genotype-Tissue Expression project and public archives to assess the transcriptional expression profiles of SNPs across 4.6 Mb spans around the novel maternal iDMRs. We showed that PARD6G-AS1 and GCSAML are expressed biallelically in multiple tissues. We found evidence of tissue-specific monoallelic expression of ZNF124 and OR2L13, located 363 kb upstream and 419 kb downstream, respectively, of the GCSAML iDMR. We hypothesize that the GCSAML

Background and aims To review the conceptual and empirical relationship between gambling, investing, and speculation. Methods An analysis of the attributes differentiating these constructs as well as identification of all articles speaking to their empirical relationship. Results Gambling differs from investment on many different attributes and should be seen as conceptually distinct. On the other hand, speculation is conceptually intermediate between gambling and investment, with a few of its attributes being investment-like, some of its attributes being gambling-like, and several of its attributes being neither clearly gambling or investment-like. Empirically, gamblers, investors, and speculators have similar cognitive, motivational, and personality attributes, with this relationship being particularly strong for gambling and speculation. Population levels of gambling activity also tend to be correlated with population level of financial speculation. At an individual level, speculation has a particularly strong empirical relationship to gambling, as speculators appear to be heavily involved in traditional forms of gambling and problematic speculation is strongly correlated with problematic gambling. Discussion and conclusions Investment is distinct from gambling, but speculation and gambling have conceptual overlap and a strong empirical relationship. It is recommended that financial speculation be routinely included when assessing gambling involvement, and there needs to be greater recognition and study of financial speculation as both a contributor to problem gambling as well as an additional form of behavioral addiction in its own right.

Alternative reproductive tactics are widespread in males and may cause intraspecific differences in testes investment. Parker's sneak-guard model predicts that sneaker males, who mate under sperm competition risk, invest in testes relatively more than bourgeois conspecifics that have lower risk. Given that sneakers are much smaller than bourgeois males, sneakers may increase testes investment to overcome their limited sperm productivity because of their small body sizes. In this study, we examined the mechanism that mediates differential testes investment across tactics in the Lake Tanganyika cichlid fish Lamprologus callipterus. In the Rumonge population of Burundi, bourgeois males are small compared with those in other populations and have a body size close to sneaky dwarf males. Therefore, if differences in relative testis investment depend on sperm competition, the rank order of relative testis investment should be dwarf males > bourgeois males in Rumonge = bourgeois males in the other populations. If differences in relative testis investment depend on body size, the rank order of relative testes investment should be dwarf males > bourgeois males in Rumonge > bourgeois males in the other populations. Comparisons of relative testis investment among the three male groups supported the role of sperm competition, as predicted by the sneak-guard model. Nevertheless, the effects of absolute body size on testes investment should be considered to understand the mechanisms underlying intraspecific variation in testes investment caused by alternative reproductive tactics.

The financial assets of a healthcare organization can present many opportunities for investment. In order to develop a profitable investment program that avoids risky speculation, however, healthcare financial managers must fully understand the nature and risks of their organizations' investments. They must define and monitor their investment objectives, limitations, levels of acceptable risk and policies and conditions through a statement of investment policy and comprehensive investment guidelines.

This study focuses on revealing the relationship between uncertainty and investment probability through real option model involving investment critical trigger and project earning. Use of Matlab software on the experimental results showing that project earning volatility influences investment probability, led the authors to conclude that this notion is not always correct, as increasing uncertainty should have an inhibiting effect on investment, and that in certain situation, increasing uncertainty actually increases the investment probability and so, should have positive impact on investment.

Product reliability is of great importance to both manufacturers and customers. Building reliability into a new product is costly, but the consequences of inadequate product reliability can be costlier. This implies that manufacturers need to decide on the optimal investment in new product reliability by achieving a suitable trade-off between the two costs. This paper develops a framework and proposes an approach to help manufacturers decide on the investment in new product reliability.

The law mechanisms of regulation quality and rule of law are used to investigate how legal origins (French, English, French sub-Saharan, Portuguese and North A...

There is considerable uncertainty in the Nordic electricity system with respect to the long-term development in production capacity. The process towards liberalisation of the electricity sector started with a situation of a large capacity margin, but this margin is gradually vanishing. Since the potential investors in new production capacity are unaccustomed with investments under the new regime, it is unknown if and when investments will take place. The purpose of the present study is to analyze if and when investors choose to invest in new electricity production capacity depending on their existing portfolio of power producing units. Electricity price scenarios generated with a partial equilibrium model (Balmorel) are combined with a model of investment decisions. In this, various scenarios concerning the development in the Nordic power market, such as new transmission lines between neighbouring countries, more installed wind power, and changes in CO 2 emission trading costs, are used to investigate the consequences for investments in a natural gas fired, combined cycle power plant. The main result of the analysis is that new investments are highly sensitive to investors existing power production portfolio, as new production units affect the merit order in the power market, i.e. compete with the existing power plants.

An organism's investment in different traits to reduce predation is determined by the fitness benefit of the defense relative to the fitness costs associated with the allocation of time and resources to the defense. Inherent tradeoffs in time and resource allocation should result in differential...... investment in defense along a resource gradient, but competing models predict different patterns of investment. There are currently insufficient empirical data on changes in investment in defensive traits or their costs along resource gradients to differentiate between the competing allocation models....... In this study, I exposed tadpoles to caged predators along a resource gradient in order to estimate investment in defense and costs of defense by assessing predator-induced plasticity. Induced defenses included increased tail depth, reduced feeding, and reduced swimming activity; costs associated...

The present study examined the specificity in relations between observed withdrawn and intrusive parenting behaviors and children's internalizing and externalizing symptoms in an at-risk sample of children (ages 9 to 15 years old) of parents with a history of depression (N = 180). Given past findings that parental depression and parenting behaviors may differentially impact boys and girls, gender was examined as a moderator of the relations between these factors and child adjustment. Correlation and linear regression analyses showed that parental depressive symptoms were significantly related to withdrawn parenting for parents of boys and girls and to intrusive parenting for parents of boys only. When controlling for intrusive parenting, preliminary analyses demonstrated that parental depressive symptoms were significantly related to withdrawn parenting for parents of boys, and this association approached significance for parents of girls. Specificity analyses yielded that, when controlling for the other type of problem (i.e., internalizing or externalizing), withdrawn parenting specifically predicted externalizing problems but not internalizing problems in girls. No evidence of specificity was found for boys in this sample, suggesting that impaired parenting behaviors are diffusely related to both internalizing and externalizing symptoms for boys. Overall, results highlight the importance of accounting for child gender and suggest that targeting improvement in parenting behaviors and the reduction of depressive symptoms in interventions with parents with a history of depression may have potential to reduce internalizing and externalizing problems in this high-risk population.

An increase in the distributed generation of electricity necessitates investments in the distribution network. The current tariff regulation in the Dutch electricity industry, with its ex post evaluation of the efficiency of investments, average benchmarking and a frontier shift in the x-factor, delays these investments. In the unbundled electricity industry, the investments in the network need to be coordinated with those in the distributed generation of electricity to enable the system operators to build enough network capacity. The current Dutch regulations do not provide for a sufficient information exchange between the generators and the system operators to coordinate the investments. This paper analyses these two effects of the Dutch regulations, and suggests improvements to the regulation of the network connection and transportation tariffs to allow for sufficient network capacity and coordination between the investments in the network and in the generation of electricity. These improvements include locally differentiated tariffs that increase with an increasing concentration of distributed generation.

We introduce childcare sharing in a collective model of household behavior to investigate which factors make spouses increase or decrease their share of parental leave. The concern about future consumption motivates parents to invest in their human capital and to limit their leave duration. Using relative income and the age difference between spouses as distribution factors, we cannot reject Pareto efficiency in childcare sharing. Higher relative incomes and larger age differences shift the c...

Full Text Available Over the last half century, major world events have prompted higher education institutions to develop internationalization plans. In order engage faculty in internationalization, higher education scholars and practitioners have recommended that internationalization plans include allocated resources, such as budgets for academic exchanges, faculty development workshops, and international curricular development and research grants (Olson, Green, & Hill, 2006; Paige, 2005; Siaya & Hayward, 2003. Yet, a frequently cited obstacle to faculty engagement in internationalization plans is lack of funding (Backman, 1984; Bond, 2003; Ellingboe, 1998; Green & Olson, 2003; Steers & Ungsen, 1992; Woolston, 1983. A cross-case analysis reveals that differential investment leads to faculty engagement in internationalization plans. This article discusses how two institutions developed funds from a variety of sources and institutional levels to engage faculty in an institutional planning process. This study offers implications for institutional planning, resource dependency theory, and internationalization.

Overshoot of the earth's carrying capacity is an acute concern for sustainability initiatives that seek to equalize access to the natural resources that are requisite to meet the basic needs of humanity. Demands on nature that exceed ecological capacities compromise critical ecosystem functions that provision the inputs necessary for life. This paper draws on concepts and analytical frameworks from the natural, physical, and social sciences to assess the drivers of sustainability at the global and national level. Integrative theoretical predictions are tested in a structural equation model that advances empirical research on overshoot and outflows of foreign investments that is relatively lacking in the literature. Findings highlight the differential impacts of key aspects of economic globalization on both development and overshoot across nations. Copyright © 2014 Elsevier Inc. All rights reserved.

Security of the systems is normally interdependent in such a way that security risks of one part affect other parts and threats spread through the vulnerable links in the network. So, the risks of the systems can be mitigated through investments in the security of interconnecting links. This article takes an innovative look at the problem of security investment of nodes on their vulnerable links in a given contagious network as a game-theoretic model that can be applied to a variety of applications including information systems. In the proposed game model, each node computes its corresponding risk based on the value of its assets, vulnerabilities, and threats to determine the optimum level of security investments on its external links respecting its limited budget. Furthermore, direct and indirect nonlinear influences of a node's security investment on the risks of other nodes are considered. The existence and uniqueness of the game's Nash equilibrium in the proposed game are also proved. Further analysis of the model in a practical case revealed that taking advantage of the investment effects of other players, perfectly rational players (i.e., those who use the utility function of the proposed game model) make more cost-effective decisions than selfish nonrational or semirational players. © 2018 Society for Risk Analysis.

The authors report a semistructured interview of 328 urban Chinese parents regarding their parenting beliefs and practices with respect to their only children. Statistical analyses of the coded parental interviews and peer nomination data from the children show none of the traditional Chinese parenting or child behaviors that have been widely reported in the literature. The parenting of only children in urban China was predominantly authoritative rather than authoritarian. The parenting strategies and beliefs were child-centered, egalitarian, and warmth-oriented rather than control-oriented. Chinese parents encouraged prosocial assertiveness and discouraged behavioral constraint and modesty. The parenting of only children was also gender egalitarian in that there were few gender differences in child social behaviors and little gender differential parenting and socialization of these only children. Together with other recent studies, these findings and conclusions challenge the traditionalist view of Chinese parenting and beliefs and behaviors about child socialization.

Parental educational styles constitute one of the key elements of family socialization. The aim of the present essay is to present the results of a research project carried out in the Principality of Asturias (Spain) among 2,965 families with children of infant and primary-school age (5-8 years old). This research attempts to analyse, among other aspects, parental behaviour tendencies in child upbringing. The analysis of the results obtained allows us to: 1) identify the most common attitudinal and behavioural tendencies of parents in the upbringing of their children; 2) determine how many people have a well defined parental style, and delimit their socio-educational characteristics. Lastly, we consider the need to change some parental behaviour patterns and stress the importance of family education programmes, with the aim of promoting appropriate parenting models and modifying or improving current practices.

Challenges in adoptive parenting continue to emerge as adoption policies and practices evolve. We review three areas of research in adoptive parenting that reflect contemporary shifts in adoption. First, we highlight recent findings concerning openness in adoption contact arrangements, or contact between a child's families of birth and rearing. Second, we examine research regarding racial and cultural socialization in transracial and international adoptions. Finally, we review investigations of parenting experiences of lesbian and gay adoptive parents. Overall, parenting processes (e.g., supportive vs. problematic family interaction) are better predictors of child adjustment than are group differences (e.g., open vs. closed adoptions; adoption by heterosexual vs. same-sex parents). The distinctive needs of adopted children call for preparation of adoption-competent mental health, casework, education, and health care professionals. Copyright © 2017 Elsevier Ltd.

The methods of investment accounting are always required if, as it is usual for buildings, payments are not due once but repeatedly within a period of several years. These payments are presented in a payment model from which an informative and reliable total value of all costs and yields can be derived. The report deals nearly exclusively with the so-called dynamic investment accounting method as it records the payment procedures as to time much more exactly than the static investment accounting method. The problem of continually rising amounts of regular payments as e.g. energy prices can be better represented by the dynamic method. Therefore, the static methods have been dealt with only globally.

As liberalisation of global trade and investment accelerates, what happens to the environment? As the world heads for confrontation in Seattle, the questions intensify. Does foreign direct investment mean forsaking environmental protection? Or do multinational corporations export higher standards when they invest abroad? Can a powerful trading nation ban imports of tropical timber produced unsustainably? Should the World Trade Organisation take the views of industry or environmental groups into account when deciding? Must world trade rules be changed to accommodate environmental concerns? This book analyzes key issues in this increasingly controversial arena and includes contributions from Renato Ruggiero, former Director General of the World Trade Organization; The Rt Hon Brian Wilson MP, former UK Minister of Trade; Dr Magda Shahin, Deputy Assistant Minister of Foreign Affairs at the Egyptian Ministry of Foreign Affairs; Pradeep Mehta, Secretary General, Consumer Unity and Trust Society, India; and Dr Michel Potier, Head of the Economics Division at the OECD's Environment Directorate.

Full Text Available Theories of kin selection and parental investment predict stronger investment in children and grandchildren by women and maternal kin. Due to paternity uncertainty, parental and grandparental investments along paternal lineages are based on less certain genetic relatedness with the children and grandchildren. Additionally, the hypothesis of preferential investment (Laham, Gonsalkorale, and von Hippel, 2005 predicts investment to vary according to available investment options. Two previous studies have tested this hypothesis with small samples and conflicting results. Using the second wave of the large and multinational Survey of Health, Ageing and Retirement in Europe (SHARE, collected in 2006–07, we study the preferential investment hypothesis in contemporary Europe based on self-reported grandparental provision of child care. We predict that 1 maternal grandmothers provide most care for their grandchildren, followed by maternal grandfathers, paternal grandmothers and last by paternal grandfathers; 2 maternal grandfathers and paternal grandmothers provide equal amounts of care when the latter do not have grandchildren via a daughter; 3 women who have grandchildren via both a daughter and a son will look after the children of the daughter more; and 4 men who have grandchildren via both a daughter and a son will look after the children of the daughter more. Results support all four hypotheses and provide evidence for the continuing effects of paternity uncertainty in contemporary kin behavior.

Full Text Available Estimating the early parent–child bonding relationship can be valuable in research and practice. Retrospective dimensional measures of parental bonding provide a means for assessing the experience of the early parent–child relationship. However, combinations of dimensional scores may provide information that is not readily captured with a dimensional approach. This study was designed to assess the presence of homogeneous groups in the population with similar profiles on parental bonding dimensions. Using a short version of the Parental Bonding Instrument (PBI, three parental bonding dimensions (care, authoritarianism, and overprotection were used to assess the presence of unobserved groups in the population using latent profile analysis. The class solutions were regressed on 23 covariates (demographics, parental psychopathology, loss events, and childhood contextual factors to assess the validity of the class solution. The results indicated four distinct profiles of parental bonding for fathers as well as mothers. Parental bonding profiles were significantly associated with a broad range of covariates. This person-centered approach to parental bonding has broad utility in future research which takes into account the effect of parent–child bonding, especially with regard to “affectionless control” style parenting.

Bateman's principle predicts the intensity of sexual selection depends on rates of increase of fecundity with mating success for each sex (Bateman slopes). The sex with the steeper increase (usually males) is under more intense sexual selection and is expected to compete for access to the sex under less intense sexual selection (usually females). Under Bateman and modern refinements of his ideas, differences in parental investment are key to defining Bateman slopes and thus sex roles. Other theories predict sex differences in mating investment, or any expenditures that reduce male potential reproductive rate, can also control sex roles. We focus on sexual behaviour in systems where males have low paternal investment but frequently mate only once in their lifetimes, after which they are often killed by the female. Mating effort (=terminal investment) is high for these males, and many forms of investment theory might predict sex role reversal. We find no qualitative evidence for sex role reversal in a sample of spiders that show this extreme male investment pattern. We also present new data for terminally-investing redback spiders (Latrodectus hasselti). Bateman slopes are relatively steep for male redbacks, and, as predicted by Bateman, there is little evidence for role reversal. Instead, males are competitive and show limited choosiness despite wide variation in female reproductive value. This study supports the proposal that high male mating investment coupled with low parental investment may predispose males to choosiness but will not lead to role reversal. We support the utility of using Bateman slopes to predict sex roles, even in systems with extreme male mating investment.

This paper investigates investment strategies that exploit the low-beta anomaly. Although the notion of buying low-beta stocks and selling high-beta stocks is natural, a choice is necessary with respect to the relative weighting of high-beta stocks and low-beta stocks in the investment portfolio. Our empirical results for US large-cap stocks show that this choice is very important for the risk-return characteristics of the resulting portfolios and their sensitivities to common risk factors.

To address the broad range of environmental issues in central and eastern Europe, including the former Soviet Union, the European Bank for Reconstruction and Development has adopted a twofold operational strategy: a regional programme approach and a project-based approach. The Bank is undertaking studies of environmental legislation and standards, and of training, liability and public participation requirements in the countries where it operates. It has also initiated environmental assessments in sectors where future investment projects are anticipated. The principal objectives of this work are to assist the countries of central and eastern Europe, those who wish to invest in these countries and Bank staff in their environmental appraisal work

In the investment property market, not only does rating provide transparency of property risk, but it can also be used for real estate portfolio analysis, investment controlling, and the analysis of factors determining investment decisions (ESV 2012.

To combat childhood obesity, researchers have focused on parental feeding practices that promote child health. The current study investigated how parenting style relates to twelve parental feeding practices. Data on parenting style and parental feeding practices were obtained for a correlational study from users of Amazon's Mechanical Turk, an online survey system. USA. Mothers of children aged 7-11 years (n 193). Parenting style related differentially to eleven out of the twelve measured practices. Authoritative mothers displayed more feeding practices that promote child health and fewer practices that impede child health. Authoritarian and permissive mothers displayed more unhealthy practices than authoritative mothers, but differed from each other on the practices they employed. Parenting style may relate to more aspects of feeding than previously realized. The inclusion of numerous healthy feeding practices along with unhealthy practices in the current study provides suggestions for the application of healthy feeding behaviours. Instruction on feeding behaviours and parenting style should be a focus of future educational programmes.

The future for oil producers in the Gulf is discussed and the emphasis is very much on Saudi Arabia. The net source flow to developing countries is illustrated but substantial changes are expected soon due to a combination of crises in the Far East and in Russia. Foreign investment in Saudi increased dramatically in 1997 and Saudi has great potential for maximising inward flows and minimising outward flows for the benefit of the national economy. It was stressed that at present, international factors are largely negative but domestic factors are very positive and will prevail in determining investments. The paper was presented under the sub-headings of (i) oil prices, (ii) the Asian crisis, (iii) stability in the Middle East, (iv) population growth (v) private sector viability, (vi) redefining the role of the state and (vii) long-term oil revenue prospects. Saudi Arabia is expected to continue to be a major player in the petroleum business

We study an investment model in which agents have the wrong beliefs about the dynamic properties of fundamentals. Specifically, we assume that agents underestimate the rate of mean reversion. The model exhibits the following six properties: (i) Beliefs are excessively optimistic in good times and excessively pessimistic in bad times. (ii) Asset prices are too volatile. (iii) Excess returns are negatively autocorrelated. (iv) High levels of corporate profits predict negative future excess returns. (v) Real economic activity is excessively volatile; the economy experiences amplified investment cycles. (vi) Corporate profits are positively autocorrelated in the short run and negatively autocorrelated in the medium run. The paper provides an illustrative model of animal spirits, amplified business cycles, and excess volatility.

Full Text Available Mobilizing financial resources to cover investment needs is a concern of all countries, developed or developing ones, of consolidated market economies or emerging ones. A distinctive characteristic of Global Economy over the last few decades has been the rising rate and impressive increase in Foreign Direct Investment (FDI. The purpose of this research is to analyse global FDI inflows in Europe and in Romania. The results of the research support the idea that the balance of economic power is changing in the world economy and the countries that own a stable and solid industrial base are at an advantage. The new trends determined by the economic crisis in the field of FDI refer to the growing percentage of developing and emerging countries in the global flows of FDI.

When evaluating new investment projects, oil companies traditionally use the discounted cashflow method. This method requires expected cashflows in the numerator and a risk adjusted required rate of return in the denominator in order to calculate net present value. The capital expenditure (CAPEX) of a project is one of the major cashflows used to calculate net present value. Usually the CAPEX is given by a single cost figure, with some indication of its probability distribution. In the oil industry and many other industries, it is common practice to report a CAPEX that is the estimated 50/50 (median) CAPEX instead of the estimated expected (expected value) CAPEX. In this article we demonstrate how the practice of using a 50/50 (median) CAPEX, when the cost distributions are asymmetric, causes project valuation errors and therefore may lead to wrong investment decisions with acceptance of projects that have negative net present values.

Recent work in human behavioural ecology has suggested that analyses focusing on early childhood may underestimate the importance of paternal investment to child outcomes since such investment may not become crucial until adolescence or beyond. This may be especially important in societies with a heritable component to status, as later investment by fathers may be more strongly related to a child's adult status than early forms of parental investment that affect child survival and child health. In such circumstances, the death or absence of a father may have profoundly negative effects on the adult outcomes of his children that cannot be easily compensated for by the investment of mothers or other relatives. This proposition is tested using a multigenerational dataset from Bangalore, India, containing information on paternal mortality as well as several child outcomes dependent on parental investment during adolescence and young adulthood. The paper examines the effects of paternal death, and the timing of paternal death, on a child's education, adult income, age at marriage and the amount spent on his or her marriage, along with similar characteristics of spouses. Results indicate that a father's death has a negative impact on child outcomes, and that, in contrast to some findings in the literature on father absence, the effects of paternal death are strongest for children who lose their father in late childhood or adolescence.

This paper studies an environment in which information aggregation interacts with investment decisions. The first contribution of the paper is to develop a tractable model of such interactions. The second contribution is to solve the model in closed form and derive a series of implications that result from the interplay between information aggregation and the value of market information for the firms' decision problem. We show that the model generates an information aggregation wedge between ...

A lack of commonly accepted benchmarks for hedge fund performance has permitted hedge fund managers to attribute to skill returns that may actually accrue from market risk factors and illiquidity. Recent innovations in hedge fund replication permits us to estimate the extent of this misattribution. Using an option-based model, we find evidence that the value of liquidity options that investors implicitly grant managers when they invest may account for part or even all hedge fund returns. C...
Although the vast majority of renewable energies projects are established by commercial developers, some of them are financed by ''ordinary citizens'' pooling together through different schemes. This is particularly frequent in Denmark and Germany, possibly a key reason for the continuous and so successful growth of various renewable energies sources in these countries. This guideline aims to define the term of local investment and provides examples of development and recommendations. (A.L.B.)

We provide a novel theoretical analysis of how index investing affects capital market equilibrium. We consider a dynamic exchange economy with heterogeneous investors and two Lucas trees and find that indexing can either increase or decrease the correlation between stock returns and in general increases (decreases) volatilities and betas of stocks with larger (smaller) market capitalizations. Indexing also decreases market volatility and interest rates, although those effects are weak. The im...

Hospital capital investment is important for acquiring and maintaining technology and equipment needed to provide health care. Reduction in capital investment by a hospital has negative implications for patient outcomes. Most hospitals rely on debt and internal cash flow to fund capital investment. The great recession may have made it difficult for hospitals to borrow, thus reducing their capital investment. I investigated the impact of the great recession on capital investment made by California hospitals. Modeling how hospital capital investment may have been liquidity constrained during the recession is a novel contribution to the literature. I estimated the model with California Office of Statewide Health Planning and Development data and system generalized method of moments. Findings suggest that not-for-profit and public hospitals were liquidity constrained during the recession. Comparing the changes in hospital capital investment between 2006 and 2009 showed that hospitals used cash flow to increase capital investment by $2.45 million, other things equal.

Full Text Available This article presents the financial investment approach and the investment evaluation methods, which are criteria for assessing both investment projects and their funding sources. An important role in the analysis carried out is played by the investment decision and financing decision quality. Making an investment decision implies computing the related investment efficiency indicators. They allow the comparison of several variants of the same investment project as well as their comparison with other projects in the same industry or in other industries. The financing decision concerns the selection between their own sources (share capital, depreciation fund, profits, reserve funds, additional capital, revenues from investments, attracted sources (domestic resource mobilization and borrowed sources (credits.

Debt priority rules, i.e., the rules determining how different classes of debt split the firm's assets after bankruptcy, influence the firm's investment decisions. Existing debt benefits from an investment either because the investment is equity financed or because new debt issued to (partly......) finance the investment has lower priority in the event of bankruptcy as is the case for the commonly used absolute priority rule (APR). This incentivizes equity holders to under invest. If debt priority rules are specified in such a way that existing debt can be exploited by issuing new debt, do equity...... holders have the incentive to over invest. We formulate a dynamic structural model to study the interaction of initial capital structure choice, investment policy, subsequent debt issues, and debt priority rules. We find that priority rules have a substantial impact on investment timing as well...

This paper examines how the relative shares of public and private health expenditures impact income inequality. We study a two period overlapping generation's growth model in which longevity is determined by both private and public health expenditure and human capital is the engine of growth. Increased investment in health, reduces mortality, raises return to education and affects income inequality. In such a framework we show that the cross-section earnings inequality is non-decreasing in the private share of health expenditure. We test this prediction empirically using a variable that proxies for the relative intensity of investments (private versus public) using vaccination data from the National Sample Survey Organization for 76 regions in India in the year 1986-87. We link this with region-specific expenditure inequality data for the period 1987-2012. Our empirical findings, though focused on a specific health investment (vaccines), suggest that an increase in the share of the privately provided health care results in higher inequality.

The study investigated the relationship between academic anxiety and procrastination in children and parents, and parents' direct involvement in their children's schoolwork. Children reported their current anxiety and procrastination and parents reported their anxiety and procrastination when they were children (a measure of indirect influence on their children's schoolwork habits), and on their current involvement in their children's schoolwork (a measure of direct influence). Self-report measures were administered to 354 Israeli adolescents (ages 13, 14, and 16) and their parents. Students were less anxious about homework than the other academic assignments. Older adolescents were less anxious about their schoolwork overall and procrastinated more than younger on homework. Parents of late adolescents were less involved in their children's schoolwork than parents of younger adolescents. Parents participated equally in school-related interactions that demanded high investment of time and effort, but mothers engaged more than fathers in low investment activities. These direct and indirect parental influences on their children's procrastination were of low magnitude overall, but appeared relatively stronger for mothers. The more students were anxious about preparing for examinations and writing papers, the more they procrastinated on these assignments, confirming the appraisal-anxiety avoidance (AAA) model. The inverse relationship of anxiety and procrastination with regard to homework led to our making a post hoc distinction between task-centred and consequence-centred anxiety.

This paper examines the investment decisions of older individual investors. We find that older and experienced investors are more likely to follow rules of thumb that reflect greater investment knowledge. However, older investors are less effective in applying their investment knowledge and exhibit worse investment skill, especially if they are less educated, earn lower income, and belong to minority racial/ethnic groups. Overall, the adverse effects of aging dominate the positive effects of ...

This report examines investment in domestic uranium exploration by US companies. In addition to examining the influence of typically considered variables such as expected price of output, expected cost of production, cost of capital, and reserve holdings, the analysis also considers the influence of selected attributes of the corporations involved, including cash flow, exploration expertise, and corporate investment strategy. This latter class of variables (i.e., corporate variables) has never been considered in the analysis of the determination of industry investment behavior. The sample includes observations of 25 firms' behavior over a period of 7 years, 1973 through 1979. In addition to supporting the energy Information Administration's more comprehensive uranium market modelling efforts, an interesting question this study addresses is the role of major oil companies in the uranium exploration field. The results suggest that expected profit and level of reserve holdings significantly affect exploration effort. It is also found that firms with greater cash flow and depth of in-house exploration expertise will explore more than firms with less. On the other hand, the results do not suggest that firms' diversification strategies differentiate their exploration in the short run. For instance, in the uranium industry, mineral firms do not behave differently from energy (e.g., oil) firms, once the other determinants of investment in exploration are considered. In conclusion, the results demonstrate that corporate variables should be considered in models of uranium exploration. Their consideration will enhance the ability to model exploration behavior accurately. 10 tables

Although parents are acknowledged to be a part of their children's personality and narrative identity and to remain important across the life span, narrative personality research has not yet explored the spontaneous presentation of parents in life stories. Therefore, this study examined longitudinally the place given to parents when crafting one's life narrative and how this changes with age. Furthermore, in contrast to prior studies, we focused on spontaneous mentions of parents. We investigated how often parents are mentioned in life narratives of six age groups spanning from age 8 to 69, how the parental relationship is evaluated, whether narrators express understanding of their parents, and whether they respond to parental values. People of all ages dedicated a substantial part of their life narratives to their parents and evaluated their relationship with them in an increasingly differentiated manner. Parents were increasingly perceived as individuals beyond their parental nurturing role. Until late in life, individuals reflect on values and opinions that were transferred to them by their parents. Parents hold a consistent place in life narratives, emphasizing their importance for narrative identity. Results are discussed in terms of lifelong child-parent relationships.

Since the minimal investment risk is influenced by the investment concentration constraint (as well as the budget constraint), it is intuitive that the minimal investment risk for the problem with an investment concentration constraint can be larger than that without the constraint (that is, with only the budget constraint). Moreover, a numerical experiment shows the effectiveness of our proposed analysis. In contrast, the standard operations research approach failed to identify accurately the minimal investment risk of the portfolio optimization problem.
Full Text Available Rapid development of financial markets resulted new challenges for both investors and investment issues. This increased demand for innovative, modern investment and portfolio management decisions adequate for market conditions. Financial market receives special attention, creating new models, includes financial risk management and investment decision support systems.Researchers recognize the need to deal with financial problems using models consistent with the reality and based on sophisticated quantitative analysis technique. Thus, role mathematical modeling in finance becomes important. This article deals with various investments decision-making models, which include forecasting, optimization, stochatic processes, artificial intelligence, etc., and become useful tools for investment decisions.
Full Text Available This paper aims to add contribution to the socially responsible investments (from now on called “SRI” research by examining the significance of this type of investment in terms of ethical or financial prior behaviour. Using the sample of European market of socially responsible investments funds, we first explore the SRI market dimension compared to the global data on SRI. We also investigate whether the ethical recognition is more important rather than the financial performance. Applied to the European social responsible investment fund market, the paper investigates the difference between these two aspects of behaviour and underlies the importance of socially responsible investments in promoting a sustainable development.

Full Text Available Investments play a key part within the goods and services industry, consumerism and community as well. The effects generated by any investment project substantiate this statement, regardless the sector of activity in which they are implemented. In the current market economy, economic efficiency indicators are playing an important role in assessing and analyzing an investment project since due to these indicators, the investor can become aware of the most important aspects they need to respond promptly. In this respect, we conducted a market analysis of real estate investments in Romania, highlighting economic and social efficiency of property investments.
Diana Baumrind's typology of parenting is based on a two-factor model of "control" and "warmth". Her recommended discipline style, labeled "authoritative parenting", was constructed by taking high scores on these two factors. A problem with authoritative parenting is that it does not allow for flexible and differentiated responses to discipline…

Drug therapy combined with family therapy is currently the best treatment for adolescent depression. Nevertheless, family therapy requires an exploration of unresolved problems in the family system, which in practice presents certain difficulties. Previous studies have found that the perceptual differences of family function between parents and children reflect the problems in the family system. To explore the characteristics and role of family functioning and parent-child relationship between adolescents with depressive disorder and their parents. The general information and clinical data of the 93 adolescents with depression were collected. The Family Functioning Assessment Scale and Parent-child Relationship Scale were used to assess adolescents with depressive disorder and their parents. a) The dimensions of family functioning in adolescents with depressive disorder were more negative in communication, emotional response, emotional involvement, roles, and overall functioning than their parents. The differences were statistically significant. Parent-child relationship dimensions: the closeness and parent-child total scores were more negative compared with the parents and the differences were statistically significant. b) All dimensions of parent-child relationship and family functioning in adolescents with depression except the time spent together were negatively correlated or significantly negatively correlated. c) The results of multivariate regression analysis showed: the characteristics of family functioning, emotional involvement, emotional response, family structure, and income of the adolescents with depressive disorder mainly affected the parent-child relationship. There were perceptual differences in partial family functioning and parent-child relationship between adolescents with depressive disorder and their parents. Unclear roles between family members, mutual entanglement, too much or too little emotional investment, negligence of inner feelings

investment, negligence of inner feelings, parental divorce, and low average monthly family income were the main factors causing adverse parent-child relationship. These perceptual differences have a relatively good predictive effect on family problems, and can be used as an important guide for exploring the family relationship in family therapy. PMID:29719348
Full Text Available The main aim of the article is evaluation of investment processes in agriculture in Poland in 2000-2011. Tendencies in range of investment activity after 2000 should by favourably estimate. Essential improvement in this area has happened especially after integration with the EU, in relationship to possibilities of funding investments by union funds. Also the enlargement of integration investment activity in agriculture has been noticed on background of tendency in total economy. In spite an increasing tendency in case of ability to invest in agriculture, its level was insufficient to set – back decapitalization of fixed assets in the whole agriculture. The situation would be positive if the tendency of growth degree of consumption of assets was stopped. On the other hand, awareness is necessary of the considerable differentiation in relation to investment activity with regard to the scale of production. It can be supposed, that started investment processes will bring to a part of agricultural farms multiplied effects which will actively use the investment support under the CAP instruments and preferential credits. It will intensify the processes of polarization in agriculture.

We argue that the trend toward international investment agreements (IIAs) with stricter investment rules is driven by competitive diffusion, namely defensive moves of developing countries concerned about foreign direct investment (FDI) diversion in favor of competing host countries. Accounting for spatial dependence in the formation of bilateral investment treaties (BITs) and preferential trade agreements (PTAs) that contain investment provisions, we find that the increase in agreements with ...

As the Internet's presence in health care grows more pervasive, an increasing number of health care providers have begun to implement eHealth innovations in their practice. This book explores the development of a model to predict and explain the degree of success it is possible to achieve in implementing e-health systems. This model allows an institution to benchmark its progress towards IHCS implementation and advises administrators where to invest resources to increase the chance of successful implementation. A set of case studies highlights key features of the model, with each case study fu
By introducing an exhaustible resource into an AK growth model, we can identify the determinants of the scale of green investment needs and its impact on capital accumulation dynamics. The role of green capital in the transition to a low-carbon economy depends, in particular, on the relative magnitudes of the elasticities of demand for polluting goods and of the substitutability between green capital and natural resources. The impact on the optimal savings rate also depends on the productivity of green capital and on the ability to adapt existing capital
A portfolio of different stocks and a risk-less security whose composition is dynamically maintained stable by trading shares at any time step leads to a growth of the capital with a nonrandom rate. This is the key for the theory of optimal-growth investment formulated by Kelly. In presence of transaction costs, the optimal composition changes and, more important, it turns out that the frequency of transactions must be reduced. This simple observation leads to the definition of an optimal lag...

We show that there is a negative relation between leverage and future growth at the firm level and, for diversified firms, at the segment level. Further, this negative relation between leverage and growth holds for firms with low Tobin's q, but not for high-q firms or firms in high-q industries. Therefore, leverage does not reduce growth for firms known to have good investment opportunities, but is negatively related to growth for firms whose growth opportunities are either not recognized by ...
A steady expansion of nuclear capacity in the European Community is one of the major ways of preventing unacceptable rises in oil imports. Over the period 1978 to 1985, the creation of the necessary nuclear capacity will require about Pound42000 million, and to help utilities Euratom is prepared to provide loans up to 20 per cent of the total investment cost of a project. The purpose is to complement, not replace, traditional financing resources. Fuel cycle facilities may be prominent in future loans. (U.K.)

Research efforts to allow large-scale conversion of cellulose into biofuels are being undertaken in the US and EU. These efforts are designed to increase logistic and conversion efficiencies, enhancing the economic competitiveness of cellulosic biofuels. However, not enough attention has been paid to the future market conditions for cellulosic biofuels, which will determine whether the necessary private investment will be available to allow a cellulosic biofuels industry to emerge. We examine the future market for cellulosic biofuels, differentiating between cellulosic ethanol and 'drop-in' cellulosic biofuels that can be transported with petroleum fuels and have equivalent energy values. We show that emergence of a cellulosic ethanol industry is unlikely without costly government subsidies, in part because of strong competition from conventional ethanol and limits on ethanol blending. If production costs of drop-in cellulosic biofuels fall enough to become competitive, then their expansion will not necessarily cause feedstock prices to rise. As long as local supplies of feedstocks that have no or low-valued alternative uses exist, then expansion will not cause prices to rise significantly. If cellulosic feedstocks come from dedicated biomass crops, then the supply curves will have a steeper slope because of competition for land. (author)

Parental protection of eggs represents one of the most basic forms of parental care. Theory suggests that even such basic parental investment represents a trade-off between current offspring survival and future reproductive success. However, few studies have quantified the underlying costs and benefits of parental care for marked individuals across an entire lifetime. I marked and followed 370 females of Publilia concava (Hemiptera: Membracidae) that exhibited a range of guarding durations fo...
The mission of Environmental Management's (EM) Office of Technology Development (OTD) Innovation Investment Area is to identify and provide development support for two types of technologies that are developed to characterize, treat and dispose of DOE waste, and to remediate contaminated sites. They are: technologies that show promise to address specific EM needs, but require proof-of-principle experimentation; and (2) already proven technologies in other fields that require critical path experimentation to demonstrate feasibility for adaptation to specific EM needs. The underlying strategy is to ensure that private industry, other Federal Agencies, universities, and DOE National Laboratories are major participants in developing and deploying new and emerging technologies. To this end, about 125 different new and emerging technologies are being developed through Innovation Investment Area's (IIA) two program elements: RDDT ampersand E New Initiatives (RD01) and Interagency Agreements (RD02). Both of these activities are intended to foster research and development partnerships so as to introduce innovative technologies into other OTD program elements for expedited evaluation
The main objective of the project is to investigate different types of molding rubbers used for investment casting. The level of shape complexity which can be achieved by using these rubber molds is also studied. It was almost impossible to make complex shapes molds using metal molds, in that cases rubber molds are very important because they arc flexible and give accurate and precise part dimensions. Turbine blades are hi-tech components with air-foil geometries that have close dimensional tolerances. They are made of super-alloys and manufactured by investment casting. The final blade profile depends upon the dimensional accuracy in each of the processing steps. In the present work experimental study for the production of high quality low cost castings of turbine blades using rubber molds and injected wax patterns is presented. Natural Rubber molds and wax patterns from these molds were made. Different types of molding rubbers were studied including natural rubber, silicone rubber and liquid silicone rubber. It was found that by using rubber molds we can make most complex shape with very less finishing required. The shrinkage was 12% as compared to original master pattern. Rubber molds were made using laboratory hot press. Three layers of rubber above and below the master pattern. After that vulcanization was done by giving temperature and pressure. (author)
Information and communication systems can improve the timeliness and quality of decisions. These benefits are strategically important to the utility industry in an era of increasing competition. Because these systems often do not reduce labor cost, however, they can be difficult to evaluate. This report presents a new process for reaching consensus of the value of capital investment in information and communication systems. The results of this project is A Strategic Advocacy Process (ASAP), a methodology that can be used to evaluate investments in information technology. ASAP uses belief graphs to produce a living business case showing facts, assumptions, goals, and metrics for measuring progress toward those goals; shows how to use option pricing theory to quantify the value of managerial flexibility; ASAP uses an organizational impact assessment tool to identify the potential impact of new information systems and how to realize the benefits of managerial flexibility. The ASAP methodology addresses the critical problem of correctly valuing information and communication systems. The methodology offers a way to account for the ''intangible'' value of these systems by recognizing the managerial flexibility these systems can provide in addressing risks and uncovering new business opportunities. Metrics for measuring progress toward new goals can be defined, and plans for achieving the goals can be made. As a result, agreement can be reached on the uses, value, and priority of projects based on a metric other than on labor replacement savings

subsidiaries located in Europe. Our results indicate that the external embeddedness of the MNC is an antecedent to headquarters' value creation. We find that headquarters' investments into their own relationships with the subsidiaries' contexts are positively related to the value added by headquarters....... Furthermore, this relationship is stronger when the subsidiary itself is strongly embedded. We discuss implications for the MNC literature, embeddedness research, and the literature on parenting and headquarters' roles......What determines the value an MNC's headquarters adds to its own affiliates? In this paper, we shed light on this question by linking the embeddedness view of the multinational corporation to the literature on parenting advantage. We test our hypotheses on an original dataset of 124 manufacturing...
Full Text Available Modern conditions of economic systems development have necessitated more precise directions of investment process for the economic growth to accelerate. The precipitous fall of oil prices that occurred in the second half of 2014 weighed heavily on foreign direct investment flows to oilexporting countries. The problem of attracting investment is one of the key problems of economic development. The aim of this study is to analyze and evaluate the shifts in the structure of investments, the study of the structure of investments to the Russian economy. Structural changes result from differences in the growth rate of the elements forming an economic system. An integral coefficient has been used for evaluation of structural changes. Multiple regression was used to analyze the impact of various factors on the change in structure of investment. The regression coefficients in the model give quantitative assessment of the pace of change in the structure as it depends on a specific factor. The model estimation shows that the variables “share of investments in manufacturing” (positive influence and “share of investments in the health, physical culture, education” (negative influence have the largest t-values. Hence, these two factors influence the structural changes in investments most strongly The evaluation and analysis of the structural shifts may lead to conclusions regarding the efficiency of the structure investment and adjustment of the economic policy.

Care around birth may impact child and mother health and parental health investments. We exploit the 2008 national strike among Danish nurses to identify the effects of care around birth on infant and mother health (proxied by health care usage) and maternal investments in the health of their newborns. We use administrative data from the population register on 39,810 Danish births in the years 2007-2010 and complementary survey and municipal administrative data on 8288 births in the years 2007-2009 in a differences-in-differences framework. We show that the strike reduced the number of mothers' prenatal midwife consultations, their length of hospital stay at birth, and the number of home visits by trained nurses after hospital discharge. We find that this reduction in care around birth increased the number of child and mother general practitioner (GP) contacts in the first month. As we do not find strong effects of strike exposure on infant and mother GP contacts in the longer run, this result suggests that parents substitute one type of care for another. While we lack power to identify the effects of care around birth on hospital readmissions and diagnoses, our results for maternal health investments indicate that strike-exposed mothers-especially those who lacked postnatal early home visits-are less likely to exclusively breastfeed their child at four months. Thus reduced care around birth may have persistent effects on treated children through its impact on parental investments. Copyright © 2016 Elsevier Ltd. All rights reserved.

Youth athlete specialization has been linked to decreased enjoyment, burnout, and increased injury risk, although the impact of specialization on athletic success is unknown. The extent to which parents exert extrinsic influence on this phenomenon remains unclear. The goal of this study was to assess parental influences placed on young athletes to specialize. It was hypothesized that parents generate both direct and indirect pressures on specialized athletes. Cross-sectional study; Level of evidence, 3. A survey tool was designed by an interdisciplinary medical team to evaluate parental influence on youth specialization. Surveys were administered to parents of the senior author's orthopaedic pediatric patients. Of the 211 parents approached, 201 (95.3%) completed the assessment tool. One-third of parents stated that their children played a single sport only, 53.2% had children who played multiple sports but had a favorite sport, and 13.4% had children who balanced their multiple sports equally. Overall, 115 (57.2%) parents hoped for their children to play collegiately or professionally, and 100 (49.7%) parents encouraged their children to specialize in a single sport. Parents of highly specialized and moderately specialized athletes were more likely to report directly influencing their children's specialization ( P = .038) and to expect their children to play collegiately or professionally ( P = .014). Finally, parents who hired personal trainers for their children were more likely to believe that their children held collegiate or professional aspirations ( P = .009). Parents influence youth athlete specialization both directly and by investment in elite coaching and personal instruction. Parents of more specialized athletes exert more influence than parents of unspecialized athletes.
What is common in aggression and in abusive/neglectful parenting is low levels of empathy. Fostering empathy--the ability to identify with another person's feelings--can serve as an antidote to aggression and is crucial to good parenting. Poor parenting and aggression cut across all socioeconomic levels of the community and, as such, empathy needs to be fostered in all children. During the period of rapid brain development, adversity has a devastating impact on the baby's developing brain. Repeated experiences of stress are hardwired into the brain, creating damaging pathways. Risk factors such as domestic violence, child abuse and neglect, maternal depression, maternal addictions, and poverty are not just additive to the vulnerable developing brain; they are multiplicative in their impact. The parent is the baby's lifeline, mitigating stress for them and helping them to learn to regulate their emotions. The impact of poor parenting on a child's life is profound, resulting in insecure attachments which lead to a spectrum of inadequate coping mechanisms, poor emotional regulation, diminished learning potential and low competence. Responsive and nurturing parenting is the key to optimal early childhood development; it allows the young brain to develop in a way that is less aggressive and more emotionally stable, social and empathic. Good early childhood development leads to good human development. We must match our investment where the opportunity is most ripe--building parenting capacity. The 'Roots of Empathy' program offers real hope in breaking the intergenerational transference of poor parenting and violence.
Today's investment decisions in key sectors such as energy, forestry or transport have significant impacts on the levels of greenhouse gas (GHG) emissions over the coming decades. Given the economic and environmental long-term implications of capital investment and retirement, a climate mitigation regime should aim to encourage capital investment in climate-friendly technologies. Many factors affect technology choice and the timing of investment, including investor expectations about future prices and policies. Recent international discussions have focused on the importance of providing more certainty about future climate policy stringency. The design of commitment periods can play a role in creating this environment. This paper assesses how the length of commitment periods influences policy uncertainty and investment decisions. In particular, the paper analyses the relationship between commitment period length and near term investment decisions in climate friendly technology.
In cooperation with the Triodos Bank, SEV carried out a study on the possibility to invest money from green investment funds at low interest in houses which are designed and built in a sustainable and energy efficient way. By order of the Triodos Bank and SEV others drafted a guideline to assess dwellings and calculated the financial and economical consequences of green investments in sustainable housing. The results of those studies formed the basis of the SEV recommendation to the Dutch State Secretary of Housing and Planning and the Dutch State Secretary of Economic Affairs, April 1996, to expand the planned Green Investment Regulation to the possibility to invest money in sustainable houses. It is expected that the Green Investment Regulation will come into effect September 1996. 2 appendices

Work environment investments are important in order to create a healthy and safe workplace. This article presents findings from a seven-step interventions process aimed at examining and following-up work environment investments in small and medium-sized enterprises (SMEs), with a particular focus on air contaminants. Three different cases were analyzed and included in the study: (a) an educational center for welding; (b) a paint station in furniture manufacturing; (c) a joinery in furniture manufacturing. The results show that the work environment investments were highly appreciated by the employees and managers, but at the same time the investment could be optimized through markedly decreased exposure levels for the worker. Factors such as follow-ups of the investment, education and training in how to use the equipment, worker involvement in the process and leadership engagement are important in order to optimize work environment investments.
Nuclear power plant ownership in the United States has continued its steady trend toward ownership consolidation and removal of assets from rate regulated environments that began in 1998. This is paralleled by changes in companies providing nuclear services and growing talk of building new units. World wide, new nuclear plant construction and related supplier investment is proceeding around the world. The nuclear fuel supply part of the business is seeing interest and excitement that would have been almost inconceivable a decade ago. Nuclear is now increasingly being recognized for its energy, economic and environmental benefits. For investors, this is a time of opportunity. And the opportunity is strongly supported by excellent performance trends and fundamental change sin the US electricity business. But in order to benefit from these changes, investors must remain cautious and be committed to comprehensively and thoroughly understanding the individual and interrelated technical, regulatory and political issues that surround this useful and powerful technology.

The contribution of the green production to the world production of electricity reached 20.2% in 2011, it means a slight increase in respect to the figure of 2010: 19.8%. Green electricity is the second source of electricity behind fossil energy (67.9%) but before nuclear power (11.7%). The decrease in nuclear power due to the Fukushima accident has automatically benefited green electricity. The figures show the importance of China, China is now the first electricity producer in the world before US and also passed US for the production of green electricity. At the world scale the production of green electricity can break down into: hydro energy (80.5%), wind energy (10.3%), biomass (6.2%), geothermal energy (1.6%) and solar energy (1.4%). The crisis has slowed down the investment in renewable energies in Europe. (A.C.)
The authors provide an assessment of the venture investing opportunities in superconductivity and some guidelines to follow. There were many elements that made Silicon Valley a leader in technology, not the least of which were the distinguished research universities located here. However, the application of the research results that they produced was done by groups of extraordinary people--people who had ideas, who were willing to take risks, and who inspired others to follow them into the unknown. They sometimes succeeded, but they often didn't. However, they never stopped trying. People like that will be the key to success in advancing and applying superconductivity technology just as they have been in semiconductors
The developing countries are likely to represent the fastest growing component of the global energy demand over the next two decades. The paper presents considerations based on the World Bank's approach to the energy sector in these countries. It is considered that an accelerated development of conventional indigenous sources of energy is absolutely vital if developing countries are to attain a satisfactory rate of economic growth. The cost of the energy investment, the power sector issues, the optimal use of the resources, the role of the external financing and the need of technical assistance are reviewed. One emphasizes the role of the World Bank in analyzing and preparing projects, and in mobilizing financing from other official and commercial sources
In the early 1990s Latin America became a favoured target for foreign investors as one of the side-effects of the collapse of communism in Eastern Europe and the Soviet Union. The reason is linked to macroeconomic reforms in Latin America and the failure of equivalent reforms in the former communist countries. Latin American state-owned-oil companies have been welcomed as borrowers on the international financial markets. Simultaneously private sector investment in the oil industry has increased. This chapter examines nationalisation and the state oil companies, the financing of the state sector, privatisation, the boosting of oil exploration and security issues. The sustainability of the economic reforms in the region is discussed. (UK)
