A crucial question for artificial cognition systems is what meaning is and how it arises. In pursuit of that question, this paper extends earlier work in which we show that emergence of simple signaling in biologically inspired models using arrays of locally interactive agents. Communities of "communicators" develop in an environment of wandering food sources and predators using any of a variety of mechanisms: imitation of successful neighbors, localized genetic algorithms and partial neural net training on successful neighbors. Here we (...) focus on environmental variability, comparing results for environments with (a) constant resources, (b) random resources, and (c) cycles of "boom and bust." In both simple and complex models across all three mechanisms of strategy change, the emergence of communication is strongly favored by cycles of "boom and bust." These results are particularly intriguing given the importance of environmental variability in fields as diverse as psychology, ecology and cultural anthropology. (shrink)

Environmental variability has been proposed as an important mechanism in behavioral psychology, in ecology and evolution, and in cultural anthropology. Here we demonstrate its importance in simulational studies as well. In earlier work we have shown the emergence of communication in a spatialized environment of wandering food sources and predators, using a variety of mechanisms for strategy change: imitation (Grim, Kokalis, Tafti & Kilb 2000), localized genetic algorithm (Grim, Kokalis, Tafti & Kilb 2001), and partial training of neural (...) nets on the behavior of successful neighbors (Grim, St. Denis & Kokalis 2002). Here we focus on environmental variability, comparing results for all of these mechanisms in a range of different environments: (a) environments with constant resources, (b) environments with random resources around the same mean, and (c) sine-wave variable environments with cycles of ‘boom and bust’. Communication, it turns out, is strongly favored by environmental variability on the pattern of ‘boom and bust.'. (shrink)

Two kinds of factors set the tempo and direction of organic and cultural evolution, those external to biotic evolutionary process, such as changes in the earth’s physical and chemical environments, and those internal to it, such as the time required for chance factors to lead lineages across adaptive valleys to a new niche space (Valentine 1985). The relative importance of these two sorts of processes is widely debated. Valentine (1973) argued that marine invertebrate diversity patterns responded to seafloor spreading as (...) this process generated more or less niche space. He suggested that natural selection is a powerful force and that earth’s biota are in near equilibrium with the niches available on the geological time scale. Walker and Valentine (1984) modeled the evolution of species assuming a logistic speciation rate limited by internal factors and a diversity-independent death rate caused by ongoing environmental change. Fitting this model to the observed evolution of shelled marine invertebrates suggests that the lag between extinctions and the evolution of new species leaves perhaps 30% of ecological niches unfilled. In this model, the biota lag environmental change by perhaps a few million years. However, as Valentine (1985) notes, if adaptive landscapes have whole suites of niches protected by deep maladaptive valleys, the waiting time for some pioneering species to cross the divide may be very long, generating the rare events that set new body plans and generate major adaptive radiations. Eldredge and Gould (1972) and Gould (2002) championed the idea that internal processes such as genetic and developmental constraints, coupled with the complexity of the adaptive landscape, resulted in a highly historically contingent evolutionary process. On Gould’s account, most of the history of life had to do not with a relatively close tracking of a changing environment but with the halting evolutionary exploration a deeply fissured niche space, mostly by rapid bursts of evolution as a fissure was crossed, followed by long periods of stasis..

We propose that a top priority of the cerebral cortex must be the discovery and explicit representation of the environmental variables that contribute as major factors to environmental regularities. Any neural representation in which such variables are represented only implicitly (thus requiring extra computing to use them) will make the regularities more complex and therefore more difficult, if not impossible, to learn. The task of discovering such important environmental variables is not an easy one, since their existence (...) is only indirectly suggested by the sensory input patterns the cortex receives – these variables are “hidden.” We present a candidate computational strategy for (1) discovering regularity-simplifying environmental variables, (2) learning the regularities, and (3) using regularities in perceptual and decision-making tasks. The SINBAD computational model discovers useful environmental variables through a search for different, but nevertheless highly correlated functions of any kind over non-overlapping subsets of the known variables, this being indicative of some important environmental variable that is responsible for the correlation. We suggest that such a search is performed in the neocortex by the dendritic trees of individual pyramidal cells. According to the SINBAD model, the basic function of each pyramidal cell is (1) to discover and represent one of the regularity-simplifying environmental variables, and (2) to learn to infer the state of its variable from the states of other variables, represented by other pyramidal cells. A network of such cells – each cell just attending to representation of its variable – can function as a sophisticated and useful inferential model of the outside world. (shrink)

Developmental models that account for the metabolic effect of temperature variability on poikilotherms, such as degree-day models, have been widely used to study organism emergence, range and development, particularly in agricultural and vector-borne disease contexts. Though simple and easy to use, structural and parametric issues can influence the outputs of such models, often substantially. Because the underlying assumptions and limitations of these models have rarely been considered, this paper reviews the structural, parametric, and experimental issues that arise when using (...) degree-day models, including the implications of particular structural or parametric choices, as well as assumptions that underlie commonly used models. Linear and non-linear developmental functions are compared, as are common methods used to incorporate temperature thresholds and calculate daily degree-days. Substantial differences in predicted emergence time arose when using linear versus non-linear developmental functions to model the emergence time in a model organism. The optimal method for calculating degree-days depends upon where key temperature threshold parameters fall relative to the daily minimum and maximum temperatures, as well as the shape of the daily temperature curve. No method is shown to be universally superior, though one commonly used method, the daily average method, consistently provides accurate results. The sensitivity of model projections to these methodological issues highlights the need to make structural and parametric selections based on a careful consideration of the specific biological response of the organism under study, and the specific temperature conditions of the geographic regions of interest. When degree-day model limitations are considered and model assumptions met, the models can be a powerful tool for studying temperature-dependent development. (shrink)

Major depression etiopathogenesis is related to a wide variety of genetics, demographic and psychosocial factors, as well as to environmental factors. The objective of this study is to analyze sociodemographic and environmental variables that are related to the prevalence of depression through correlation analysis and to develop a regression model that explains the behavior of this disease from an ecological perspective. This is an ecological, retrospective, cross-sectional study. The target population was 1,148,430 individuals over the age of 16 (...) who were registered in Aragon (Spain) during 2010, with electronic medical records in the community’s primary health care centers. The spatial unit was the Basic Health Area (BHA). The dependent variable was the diagnosis of Depression and the ecological independent variables were: Demographic variables (gender and age), population distribution, typology of the entity, population structure by sex and age, by nationality, by education, by work, by salary, by marital status, structure of the household by number of members, and state of the buildings. The results show moderate and positive correlations appear with higher rates of depression in areas having a higher femininity index, higher population density, areas with a higher unemployment rate and higher average salary. The results of the linear regression show that aging +75 and rural entities act as protective factors for depression, while urban areas and deficient buildings act as risk factors. In conclusion, the ecological methodology may be a useful tool which, together with the statistical epidemiological analysis, can help in the political decision making process. (shrink)

The article examines the impact of environmental quality on shaping the development policy of Polish voivodeships. The main analytical tool used was the synthetic index of environmental quality, compiled by means of the Perkal method. It was constructed in order to organize Polish voivodeships in terms of environmental quality, which was determined in a comprehensive way on the basis of three thematic areas: advantages of the natural environment, the level of pollution of the environment as well as (...) active protective activities. The obtained values of synthetic measures were then compared to the level of economic growth of Polish regions. It was necessary in determining which voivodeships perceive the quality of the environment as the main factor enhancing their economic growth, and which treat it as a barrier to economic development.

Most behavioural genetic studies focus on genetic and environmental influences on inter-individual phenotypic differences at the population level. The growing collection of intensive longitudinal data in social and behavioural science offers a unique opportunity to examine genetic and environmental influences on intra-individual phenotypic variability at the individual level. The current study introduces a novel idiographic approach and one novel method to investigate genetic and environmental influences on intra-individual variability by a simple empirical demonstration. Person-specific non-shared (...) environmental influences on intra-individual variability of daily school feelings were estimated using time series data from twenty-one pairs of monozygotic twins over two consecutive weeks. Results showed substantial inter-individual heterogeneity in person- specific non-shared environmental influences. The current study represents a first step in investigating environmental influences on intra-individual variability with an idiographic approach, and provides implications for future behavioural genetic studies to examine developmental processes from a microscopic angle.

Although research on corporate social responsibility has grown steadily, little research has focused on CSR at the individual level. In addition, research on the role of environmental friendly organizational citizenship behaviors within CSR initiatives is scarce. In response to this gap and recent calls for further research on both individual and organizational variables of employees’ environmentally friendly, or green, behaviors, this article sheds light on the influence of these variables on three types of green employee behaviors simultaneously: recycling, energy (...) savings, and printing reduction. An initial theoretical model identifies both individual and organizational variables that affect different types of green behaviors as a stepping stone for further research. The results reveal managerial implications and future research directions on the design of effective social marketing interventions that motivate different types of OCBs in the workplace. In particular, the results suggest that creating separate interventions for each type of environmental behavior, as well as for each organization, sector, and type of organization , is necessary. In addition, this research illustrates patterns of attitudes, perceptions, and behaviors by exploring individual and organizational variables and behaviors across seven different organizations belonging to different sectors.

Egypt, a less affluent, predominantly Muslim country, suffers from numerous forms of environmental pollution, some severe. This study investigates pro-environmental behaviors of citizens in Cairo, Egypt’s largest metropolis, and studies the relationship between pro-environmental behavior and demographic variables, beliefs, values, and religiosity. Analysis shows that three types of pro-environmental behavior are present: Public Sphere, Private Sphere, and Activist Behavior, with the latter occurring less frequently. Importantly, the study identifies an ecocentric value among respondents which is correlated (...) with Public Sphere Behavior. It also confirms earlier research that characterized Egyptians’ perceptions of the environment as being set in the context of health and cleanliness. Religious teachings and religiosity are shown to be associated with pro-environmental behavior, thus lending support to the presence of an Islamic environmental ethic. (shrink)

Using a sample of Chinese listed firms in polluting industries for the period of 2008–2010, we empirically investigate whether and how Buddhism, China’s most influential religion, affects corporate environmental responsibility (CER). In this study, we measure Buddhist variables as the number of Buddhist monasteries within a certain radius around Chinese listed firms’ registered addresses. In addition, we hand-collect corporate environmental disclosure scores based on the Global Reporting Initiative (GRI) sustainability reporting guidelines. Using hand-collected Buddhism data and corporate (...) class='Hi'>environmental disclosure scores, we provide strong and robust evidence that Buddhism is significantly positively associated with CER. This finding is consistent with the following view: Buddhism can serve as social norms to evoke the consciousness of social responsibility, and thereof strengthen CER. Our findings also reveal that the positive association between Buddhism and CER is attenuated for firms with higher law enforcement index. The results are robust to various measures of Buddhism and a variety of sensitivity tests. (shrink)

Investigation of Indigenous concepts and their meanings is highly inspirational for contemporary science because these concepts represent adaptive solutions in various environmental and social milieus. Past research has shown that conceptualizations of consciousness can vary widely between cultural groups from different geographical regions. The present study explores variability among a few of the thousands of Indigenous cultural understandings of consciousness. Indigenous concepts of consciousness are often relational and inseparable from environmental and religious concepts. Furthermore, this exploration of (...) variability reveals the layers with which some Indigenous peoples understand their conscious experience of the world. Surprisingly, Indigenous understandings of global consciousness was found not to be in opposition to local consciousness. The final concluding section of this study discusses the usability of Indigenous concepts and meanings for recent scientific debates. (shrink)

Young people’s environmental attitudes and behaviors are essential for environmental conservation, hence the need to identify facilitating factors. Promoting positive development among young people may empower them to contribute actively to their environment through positive attitudes and behaviors. In the present study, we examine the associations between the 5Cs of Positive Youth Development and environmental concerns among Norwegian youth, measured through environmental attitudes, conservation behavior, and responsibility. Cross-sectional data on demographic variables, the 5Cs and environmental (...) concerns were collected from high school students. For results, Character was associated with several of the environmental variables, followed by Competence and Caring, and finally Confidence, which showed a negative association with conservation behavior. There was no significant association with Connection. While these preliminary findings pave the way for future research that should involve more representative samples, the significant associations between several of the 5Cs and the environmental factors may have some implications for policy and programs on youth development and sustainable behaviors.

Conservation Biologists have found that demographic stochasticity causes the mean time to extinction to increase exponentially with population size. This has proved helpful in analyses determining extinction times and characterizing the pathway to extinction. The aim of this investigation is to explore the possible interactions between environmental/demographic noises and the scaling effect of the mean population size with its variance, which is expected to follow Taylor’s power law relationship. We showed that the combined effects of environmental/demographic noises and (...) the scaling of population size variability interact with the population dynamics and affect the mean time to extinction.

We examine how corporate environmental responsibility affects the cost of equity capital for manufacturing firms in 30 countries. Using several approaches to estimate firms’ ex ante equity financing costs, we find in regressions that control for firm-level characteristics as well as industry, year, and country effects that the cost of equity capital is lower when firms have higher CER. This finding is robust to addressing endogeneity through instrumental variables, to using alternative specifications and proxies for the cost of equity (...) capital, and to accounting for noise in analyst forecasts. We conclude that investment in CER reduces firms’ equity financing costs worldwide. (shrink)

The trend in environmental management toward more adaptive, community-based, and holistic approaches will require new approaches to environmental valuation. In this paper, we offer a new valuation approach, one that embodies the core principles of adaptive management, which is experimental, multi-scalar, and place-based. In addition, we use hierarchy theory to incorporate spatial and temporal variability of natural systems into a multi-scalar management model. Our approach results in the consideration of multiple values within community-based ecosystem management, rather than (...) an attempt to maximise a single variable such as economic efficiency. We then offer two heuristics – one procedural and one evaluative – to guide a community toward shared goals, and to develop indicators to measure progress toward these goals. We illustrate our approach by application to environmental and developmental decisions in the Southern Appalachians. (shrink)

Memory should make more available things that are more likely to be needed. Across multiple environmental domains, it has been shown that such a system would match qualitatively the memory effects involving repetition, delay, and spacing (Schooler & Anderson, 2017). To obtain data of sufficient size to study how detailed patterns of past appearance predict probability of being needed again, we examined the patterns with which words appear in large two data sets: tweets from popular sources and comments on (...) popular subreddits. The two data sets show remarkably similar statistics, which are also consistent with earlier, smaller studies of environmental statistics. None of a candidate set of mathematical models of memory do well at predicting the observed patterns in these environments. A new model of human memory based on the environmental model proposed by Anderson and Milson (1989) did better at predicting the environmental data and a wide range of behavioral studies that measure memory availability by probability of recall and speed of retrieval. A critical variable in this model was range, the span of time over which an item occurs, which was discovered in mining the environmental data. These results suggest that theories of memory can be guided by mining of the statistical structure of the environment. (PsycInfo Database Record (c) 2023 APA, all rights reserved). (shrink)

This paper examines whether a firm’s financial performance is associated with superior environmental, social and governance scores in emerging markets of multinationals in Latin America. The study addresses the current research gap on this issue; it develops hypotheses and tests them by applying linear regressions with a data panel drawn from the Thomson Reuters Eikon™ database to analyse data on 104 multinationals from Brazil, Chile, Colombia, Mexico and Peru between 2011 and 2015. The results suggest that the relationship between (...) the ESG score and FP is significantly statistically negative. Furthermore, in examining environmental, social and governance separately to accurately determine each variable’s relationship to multilatinas’ FP, the results reveal a negative relationship. Finally, the empirical analysis provides evidence for a moderating effect of financial slack and geographic international diversification on the relationship between ESG dimensions and firms’ FP. This study furthers understanding of the relationship between ESG dimensions and FP for the Latin American business context. (shrink)

ABSTRACT:Globally, family firms are the dominant organizational form. Family involvement in business and unique family dynamics impacts organizational strategy and performance. However, family control of business has rarely been adopted as a discriminating variable in the organizations and the natural environment (ONE) research field. Drawing on the theory of planned behavior we develop a conceptual framework of the drivers of proactive environmental strategy (PES) in family firms. We argue that family involvement in business influences the attitudes, subjective norms, and (...) perceived behavioral control of a firm’s dominant coalition. Together these factors determine the extent of the dominant coalition’s intentions to undertake PES. Further, family firms with lower levels of relationship conflict within the controlling family will be more successful in translating the dominant coalition’s intentions to allocate resources for the pursuit of PES. Research implications of the theory are discussed. (shrink)

Human females are generally reserved in their sexuality, in keeping with their heavy investment in reproduction. Males tend to be less reserved. Relative to males, however, females demonstrate more variability in sexuality and are more likely to inhibit or express high levels of sexuality. The heightened variability may in part originate with genetic mechanisms that predispose females toward greater variability. Menarche, menstrual cycles, menopause, food reactions, responses to living conditions, reactions to cultural factors, and responses to sexual (...) stimuli and potential mates are unique to or are more variable among females than males. There is a correlation between the variation expressed and female reproductive potential—females tend to shift dramatically from sexual inhibition to sexual expression. Females apparently track the quality of the environment and link their sexuality to reproductive opportunities. Successful male reproduction depends less on quality environments and more on the availability of females. In short, females track the environment; males track the females. (shrink)

Residents are important participants and stakeholders in destination development. Identifying factors that assist in predicting resident pro-environmental behavior (PEB) may contribute to enhanced sustainability. Based on a traditional Chinese culture, this research constructed a model of resident PEB by introducing pro-environmental destination image (PEDI) and Confucianism as the independent and moderating variables, respectively. The structural equation modeling for 402 residents indicated the model had a satisfactory level of predictive power for PEB. The results showed that: (1) PEDI positively (...) affected residents’ environmental identity, pro-environmental attitudes, and PEB; (2) environmental identity and pro-environmental attitudes completely mediated the impact of PEDI on residents’ PEB; and (3) Confucian culture had a positive U-shaped moderating effect in the relationships among these four variables. Overall, these findings advance the understanding of the formation of PEB in Confucian culture and provide theoretical and practical implications for fostering residents’ PEB. (shrink)

In this article we describe our approach to understanding wrongdoing in medical research and practice, which involves the statistical analysis of coded data from a large set of published cases. We focus on understanding the environmental factors that predict the kind and the severity of wrongdoing in medicine. Through review of empirical and theoretical literature, consultation with experts, the application of criminological theory, and ongoing analysis of our first 60 cases, we hypothesize that 10 contextual features of the medical (...) environment (including financial rewards, oversight failures, and patients belonging to vulnerable groups) may contribute to professional wrongdoing. We define each variable, examine data supporting our hypothesis, and present a brief case synopsis from our study that illustrates the potential influence of the variable. Finally, we discuss limitations of the resulting framework and directions for future research. (shrink)

The target article provides an intermediate account of culture and freedom that is conceived to be curvilinear by treating economic development not as an adaptive outcome in response to climate but as a cause of culture parallel to climate.

We examine the role of socio-demographic factors on consumers’ pro-environmental behavior –a subset of ethical behavior and analyze its implications in an emerging market, with a sample study from India. Multivariate analysis of variance was performed as research method. Results show that males display higher PEB than their female counterparts. Married consumers score more on PEB than single. Mid-age consumers also score high on PEB than young and old-age consumers. Furthermore, highly educated consumers are more pro-environmentalist than graduates and (...) post-graduates. The novelty of this study is that centers on the use of demographic variables interactively in order to form microsegments. For instance, married men score more on PEB scale than unmarried men and women and prefer green channels even more. On the contrary, unmarried women display no hesitation in paying more for energy-efficient goods compared to married men and unmarried men. Marketers may aim in setting such PEBs as the moral standards among consumers being an easily identifiable segment as their prime target. (shrink)

There is a large literature on technology adoption and environmental management in agriculture. Included in this literature are debates about the role world view or attitudinal variables play in adoption decisions, and whether smaller farms or larger farms exhibit superior environmental performance or differ in commitment to environmental values.

Using (...) key informants interviews, purposeful sampling of farmers and a mail survey we find two environmental management types: (1) the larger-scale conservation farmer; and (2) the alternative/ecological farmer.

Noncontextual hidden variables theories, assigning simultaneous values to all quantum mechanical observables, are inconsistent by theorems of Gleason and others. These theorems do not exclude contextual hidden variables theories, in which a complete state assigns values to physical quantities only relative to contexts. However, any contextual theory obeying a certain factorisability conditions implies one of Bell's Inequalities, thereby precluding complete agreement with quantum mechanical predictions. The present paper distinguishes two kinds of contextual theories, ‘algebraic’ and ‘environmental’, and investigates when (...) factorisability is reasonable. Some statements by Fine about the philosophical significance of Bell's Inequalities are then assessed. (shrink)

This paper describes a cross-cultural research project on the relation between how people conceptualize nature and how they act in it. Mental models of nature differ dramatically among and within populations living in the same area and engaged in more or less the same activities. This has novel implications for environmental decision making and management, including dealing with commons problems. Our research also offers a distinct perspective on models of culture, and a unified approach to the study of culture (...) and cognition. We argue that cultural transmission and formation does not consist primarily in shared rules or norms, but in complex distributions of causally-connected representations across minds in interaction with the environment. The cultural stability and diversity of these representations often derives from rich, biologically-prepared mental mechanisms that limit variation to readily transmissible psychological forms. This framework addresses a series of methodological issues, such as the limitations of conceiving culture to be a well-defined system or bounded entity, an independent variable, or an internalized component of minds.

The current literature on environmental sustainability acknowledges that habits are often shaped in private life and that experiences with environmental activities in a non-work setting positively influence environmental behaviors in the work domain. However, the conditions that lead individuals to behave responsibly at work based on their environmental commitment outside the workplace remain poorly understood. We address this issue by pursuing two objectives. First, we outline archetypes of environmental behavior on and off the job and (...) classify individuals into four profiles: Apathetic, Conformist, Citizen and Enthusiast. Second, we examine a set of organizational and psychological variables that explain the likelihood of behaving in accordance with the principles of an archetype in terms of pro-environmental behavior at work. Our findings show that supervisory support, job self-efficacy and affective commitment increase the likelihood of being green at work but that environmental management practices do not. The results differ according to the profiles identified, allowing a better understanding of employees’ commitment to environmental sustainability. We conclude the paper by discussing the theoretical and managerial implications of our findings. (shrink)

Many analysts argue that environmental regulation is a barrier to innovation in business firms. A competing view holds that environmental regulation contributes to firm level innovation. This article attempts to partially reconcile these two views. The article argues that organizational and individual level variables moderate the effect of environmental regulation generally on the radicalness of innovation at the firm level. It proposes that four moderating variables the degree to which information analysis about environmental issues is centralized, (...) firm size, the intensity and integration of research and development (R&D) units within the firm, and whether regulation is perceived as an opportunity change the sign of the relationship between environmental regulation and the radicalness of firm level innovation. Empirically testable propositions are presented and a regulation innovation profile is suggested. Directions for future research and implications for practicing managers are highlighted. (shrink)

Rendell and Whitehead state that marine ecosystems are more variable than terrestrial ecosystems over time scales of months or longer. The marine environment is actually less variable than the terrestrial at these shorter time scales, and probably equally variable over centuries. This issue is important when considering claims that environmental variability affects benefits of social learning versus individual learning and genetics.

The dynamics of the "Etang de Berre", a brackish lagoon situated close to the French Mediterranean sea coast, is strongly disturbed by freshwater inputs coming from an hydroelectric power station. The system dynamics has been described as a sequence of daily typical states from a set of physicochemical variables such as temperature, salinity and dissolved oxygen rates collected over three years by an automatic sampling station. Each daily pattern summarizes the evolution, hour by hour of the physicochemical variables. This article (...) presents results of forecasts of the states of the system subjected to the simultaneous effects of meteorological conditions and freshwater releases. We recall the main step of the classification tree method used to build up the predictive model (Classification and Regression Trees, Breiman et al., 1984) and we propose a transfer procedure in order to test the stability of the model. Results obtained on the Etang de Berre data set allow us to describe and predict the effects of the environmental variables on the system dynamics with a margin of error. The transfer procedure applied after the tree building process gives a maximum gain in prediction accuracy of about 15%. (shrink)

Consumers do not always follow their ideological beliefs about the need to engage in environmentally friendly consumption. We propose that Commitment to Beliefs —the general tendency to follow one’s value-based beliefs—can help identify who is most likely to follow their environmental ideologies. We predicted that CTB would amplify the effect of beliefs prescribing environmental stewardship, or neglect, on corresponding intentions, behavior, and purchasing decisions. In two studies, CTB amplified the positive and negative effects of relevant EF ideologies on (...) EF purchase decisions, and consumption and conservation attitudes, intentions, as well as future behavior. In each study, only people with higher levels of CTB demonstrated the most ideologically consistent consumption and conservation intentions and behavior. These findings clarify who is most likely to align their decisions and lifestyles according to their sustainable consumption ideologies. The amplification effect of CTB, and the CTB variable itself, present new contributions to consumer behavior research and the domains of sustainable or ethical consumption in particular and offer wide-ranging potential for marketing practitioners and researchers.

A new etiological model is proposed for schizophrenia that combines variability‐enhancing nonspecific factors acting during development with more specific risk factors. This model is better suited than the current etiological models of schizophrenia, based on the risk factors paradigm, for predicting and/or explaining several important findings about schizophrenia: high co‐morbidity rates, low specificity of many risk factors, and persistence in the population of the associated genetic polymorphisms. Compared with similar models, e.g., de‐canalization, common psychopathology factor, sexual‐selection, or differential sensitivity (...) to the environment, this proposal is more general and integrative. Recently developed research methods have proven the existence of genetic and environmental factors that enhance developmental variability. Applying such methods to newly collected or already available data can allow for testing the hypotheses upon which this model is built. If validated, this model may change the understanding of the etiology of schizophrenia, the research models, and preventionbrk paradigms. (shrink)

Training for sustainable development is an educational challenge of prime importance. Physical activity and sports in natural environments provide training committed to sustainability and environmental education. The objective of this study was to assess the effects of an undergraduate training program in Physical Activities and Sports in Natural Environments concerned with sustainable development. A total of 113 students from the Autonomous University of Madrid who are studying a Bachelor’s Degree in Physical Activity and Sports Sciences and a Master’s Degree (...) in Teacher Training for Secondary Education and High School were involved. Specifically, we aimed to assess the impact of this training program on three dimensions related to Environmental Education. Its effect was also examined bearing in mind students’ sex, age and educational profile. Mixed-methods were used: for the quantitative approach, data were collected with the Environmental Attitude in Physical Activities in Natural Environments validated scale; for the qualitative approach individual reflective diaries completed by students that attended the program were analyzed. The results show positive effects on the students regarding the three dimensions of Environmental Education, for both the sportive and educational training profiles. The quantitative results do not present significant differences concerning the gender variable, although the qualitative information shows that female students perceived a greater environmental sensitivity during their practices. Regarding the age variable, significant differences are found in the youngest students with an educational profile. To conclude, the study ratifies that the program carried out generated improvements in terms of knowledge, behaviors and attitudes toward the environment and sustainable development. Future research should use larger samples and consider other variables related to education for sustainability. (shrink)

This article analyzes the adoption of voluntary environmental management programs by firms operating in Mexico. Mexican firms can obtain national certification (Clean Industry) and/or international certification (ISO 14001). Based on institutional entrepreneurship theory, we posit that the role played by first movers as institutional entrepreneurs is crucial if these programs are to become established with sufficient strength and appeal. This understanding is especially important in an environment where more than one program can be adopted. We tested several hypotheses on (...) the behaviors of 1328 facilities operating in Mexico, half of which (664) had certified environmental management programs. Of the 664 certified facilities, 217 were classified as early adopters. Three variables predicted the likelihood of a facility being an early adopter: (1) connected to international market, (2) in the maquila sector, and (3) linked to an industry association that offers free resources.

Understanding attitudes towards the environment is important because they often determine behaviour that either increases or decreases environmental quality. In this article we investigate the environmental worldview of the young people from Kosovo. The New Revised Environmental Paradigm Scale or New Ecological Paradigm Scale, known as NEP Scale (Dunlap et al., 2000) was used. The study involved 330 young people age 18-20. 150 young people are from secondary schools, and other (180) are from some different faculties at (...) the State University in Mitrovica. The mean score for the full NEP scale in this study was 3.48, which indicates a low endorsement of the NEP among the sample of Kosovo young people. The averages of the sub-dimensions varied between 3.08 (“Limits to growth”) and 3.73 (“Eco-crisis”). Like as others non-industrialized societies, young people from Kosovo tend to believe in the profound connection between humanity and nature, or there are no clear differences between pro-NEP and pro-DSP views. This study confirms the thesis that environmental worldviews differ across cultures. The mean value of the NEP Scale can be feasibly associated with various variables concerning general environmental attitudes. In order to discover the factors that create a pro-ecological orientation of young people in this country, additional researches are needed. (shrink)

This study aims to identify the relationship between students’ environmental value and pro-environmental behavior within a values-belief-norm framework. To conduct an empirical study, we used a sample of 558 online surveys and adopted the partial least squares path modeling method to test the relationships between variables in the conceptual model. The results indicate that EV positively predicted PEB among young adults. In addition, we highlight that risk perception and moral anger play critical chain mediating roles in the relationship (...) between EV and PEB. This study has meaningful implications for practitioners seeking to encourage the public’s ecofriendly behavior by suggesting ways to encourage RP and stimulate individuals’ moral emotions about the environment.

Identifying the determinants of human behavior is useful to adjust interventions and lead the civil society toward a stronger commitment to climate change mitigation and adaptation objectives, achieving greater support for successfully implementing environmental policies. Existing research has largely focused on case studies of pro-environmental behaviors in developed economies but there is very little evidence for developing countries. This study provides estimations of the effect of internal factors, such as sociodemographic variables, and four psychological dimensions on PEBs. Data (...) were obtained through a survey applied with future decision makers – university students – from Colombia and Nicaragua. Indices were generated for PEBs and the psychological dimensions using z-scores and Principal Component Analysis. Partial correlations were evaluated through the Ordinary Least Squares method. Our results suggest that, in order to reach the planned emission reduction targets, policy approaches should more strongly focus on educating and motivating citizens and prepare them for contributing to the environmental cause, as well as provide individual solutions to combat CC, rather than providing only information on its causes and consequences.

Literature on ethical behavior has paid little attention to the mechanism between macro-environmental variables and environmental performance. This study aims at constructing a model to examine the relationships which link cultural values, population growth, economic development, and environmental performance by incorporating the mediating role of education. The multiple linear regression model was employed to test the hypotheses on a 3-year-pooled sample of 51 countries. Empirical results conclude that national culture, economic development, and population growth would significantly influence (...) environmental performance directly. In addition, through the mediating effect of education, population growth and national culture would significantly affect environmental performance indirectly. These findings provide theoretical and managerial implications for constructing the mechanism of cultural values and ethical behavior in general and environmental management in particular. (shrink)

Corporate-level environmental information disclosure is increasingly common. This article studies the impact of a prominent media-generated sustainability ratings program, Newsweek’s 2009 ranking of the 500 largest U.S. firms. Using an event study methodology, the authors find the rankings had a significant impact on shareholder value. Firms in the top 100 experienced abnormal returns after the information release that were 0.6%–1.0% higher than returns of firms in the bottom 400. The form of the information released had significant effects as well. (...) Nuanced environmental score variables had no independent impact on market outcomes; only the final ranking mattered. This article also explores possible channels through which the rankings may have had their impact. The authors find suggestive evidence that private and public politics mechanisms were the most important. (shrink)
