This paper presents a framework based upon a relationship between environmental benefits and the investments and costs needed to implement and run company operations. As the results of environmental management become more evident it is proposed that the benefits rather than the environmental impacts are measured in the analysis of environmental performance. Four categories, or stages, are defined in this paper: “creative-green”, “expensive-green”, “inefficient-green or beginner”, and finally, the “complacent” stage. The paper describes the characteristics of each category and provides examples of indicators that could be used to measure environmental benefits. Qualitative and quantitative methods are necessary to classify companies according to the framework. It is believed that this paper can assist companies and public organisations to assess operations and projects considering their level of sustainability. The proposed framework can impact FDI and environmental policies in the public arena, and foster innovation on environmental practices within the private sector.

This study investigated how harvest and water management affected the ecology of the Pig Frog, Rana grylio. It also examined how mercury levels in leg muscle tissue vary spatially across the Everglades. Rana grylio is an intermediate link in the Everglades food web. Although common, this inconspicuous species can be affected by three forms of anthropogenic disturbance: harvest, water management and mercury contamination. This frog is harvested both commercially and recreationally for its legs, is aquatic and thus may be susceptible to water management practices, and can transfer mercury throughout the Everglades food web. ^ This two-year study took place in three major regions: Everglades National Park (ENP), Water Conservation Areas 3A (A), and Water Conservation Area 3B (B). The study categorized the three sites by their relative harvest level and hydroperiod. During the spring of 2001, areas of the Everglades dried completely. On a regional and local scale Pig Frog abundance was highest in Site A, the longest hydroperiod, heavily harvested site, followed by ENP and B. More frogs were found along survey transects and in capture-recapture plots before the dry-down than after the dry-down in Sites ENP and B. Individual growth patterns were similar across all sites, suggesting differences in body size may be due to selective harvest. Frogs from Site A, the flooded and harvested site, had no differences in survival rates between adults and juveniles. Site B populations shifted from a juvenile to adult dominated population after the dry-down. Dry-downs appeared to affect survival rates more than harvest. ^ Total mercury in frog leg tissue was highest in protected areas of Everglades National Park with a maximum concentration of 2.3 mg/kg wet mass where harvesting is prohibited. Similar spatial patterns in mercury levels were found among pig frogs and other wildlife throughout parts of the Everglades. Pig Frogs may be transferring substantial levels of mercury to other wildlife species in ENP. ^ In summary, although it was found that abundance and survival were reduced by dry-down, lack of adult size classes in Site A, suggest harvest also plays a role in regulating population structure. ^

The trend of green consumerism and increased standardization of environmental regulations has driven multinational corporations (MNCs) to seek standardization of environmental practices or at least seek to be associated with such behavior. In fact, many firms are seeking to free ride on this global green movement, without having the actual ecological footprint to substantiate their environmental claims. While scholars have articulated the benefits from such optimization of uniform global green operations, the challenges for MNCs to control and implement such operations are understudied. For firms to translate environmental commitment to actual performance, the obstacles are substantial, particularly for the MNC. This is attributed to headquarters' (HQ) control challenges (1) in managing core elements of the corporate environmental management (CEM) process and specifically matching verbal commitment and policy with ecological performance and by (2) the fact that the MNC operates in multiple markets and the HQ is required to implement policy across complex subsidiary networks consisting of diverse and distant units. Drawing from the literature on HQ challenges of MNC management and control, this study examines (1) how core components of the CEM process impact optimization of global environmental performance (GEP) and then uses network theory to examine how (2) a subsidiary network's dimensions can present challenges to the implementation of green management policies. It presents a framework for CEM which includes (1) MNCs' Verbal environmental commitment, (2) green policy Management which guides standards for operations, (3) actual environmental Performance reflected in a firm's ecological footprint and (4) corporate environmental Reputation (VMPR). Then it explains how an MNC's key subsidiary network dimensions (density, diversity, and dispersion) create challenges that hinder the relationship between green policy management and actual environmental performance. It combines content analysis, multiple regression, and post-hoc hierarchal cluster analysis to study US manufacturing MNCs. The findings support a positive significant effect of verbal environmental commitment and green policy management on actual global environmental performance and environmental reputation, as well as a direct impact of verbal environmental commitment on green policy management. Unexpectedly, network dimensions were not found to moderate the relationship between green management policy and GEP.

Sustainability assessments were carried out in small-holders? farms in four territories where productive arrangements have been organized for production of minor oleagi- nous crops under the Brazilian biodiesel program. The study aimed at checking local impacts of the biodiesel productive chains at the rural establishment scale, and pro- moting the environmental performance of the selected farms, henceforth proposed as sustainable management demonstration units. Assessments were carried out with the APOIA-NovoRural system, which integrates 62 objective and quantitative indicators re- lated to five sustainability dimensions: i) Landscape Ecology, ii) Environmental Quality (Atmosphere, Water and Soil), iii) Socio-cultural Values, iv) Economic Values and v) Management and Administration. The main results point out that, in general, the eco- logical dimensions of sustainability, that is, the Landscape Ecology and Atmosphere, Water, and Soil quality indicators, show adequate field conditions, seemingly not yet negatively affected by increases in chemical inputs and natural resources use predicted as important potential impacts of the agro-energy sector. The Economic Values indica- tors have been favorably influenced in the studied farms, due to a steadier demand and improved prices for the oleaginous crops. On the other hand, valuable positive conse- quences expected for favoring farmers? market insertion, such as improved Socio-cultural Values and Management & Administration indicators, are still opportunities to be ma-terialized. The Environmental Management Reports issued to the farmers, based on the presented sustainability assessment procedures, offer valuable documentation and com-munication means for consolidating the organizational influence of the local productive arrangements studied. These productive arrangements were shown to be determinant for the selection of crop associations and diversification, as well as for the provision of technical assistance and the stabilization of demand - conditions that promote value aggregation and income improvements, favoring small-holders? insertion in the market. More importantly, these locally organized productive arrangements have been shown to strongly influence the valorization of natural resources and environmental assets, which are fundamental if sustainable rural development is to take place under the emerging agro-energy scenario.

Heat management in mines is a growing issue as mines expand physically in size and depth and as the infrastructure grows that is required to maintain them. Heat management is a concern as it relates to the health and safety of the workers as set by the regulations of governing bodies as well as the heat sensitive equipment that may be found throughout the mine workings. In order to reduce the exposure of working in hot environments there are engineering and management systems that can monitor and control the environmental conditions within the mine. The successful implementation of these methods can manage the downtime caused by heat stress environments, which can increase overall production. This thesis introduces an approach to monitoring and data based heat management. A case study is presented with an in depth approach to data collection. Data was collected for a period of up to and over one year. Continuous monitoring was conducted by equipment that was developed both commercially and within the mine site. The monitoring instrumentation was used to assess the environmental conditions found within the study area. Analysis of the data allowed for an engineering assessment of viable options in order to control and manage the environment heat stress. An option is developed and presented which allows for the greatest impact on the heat stress conditions within the case study area and is economically viable for the mine site.

Abstract : This paper examines the factors motivating students to enrol in the Tourism Management program at Champlain College, St-Lambert and why a large number of students abandon the program before obtaining their DEC. There is a great deal of literature on student attrition, however there is little consensus on why students withdraw from college programs and the results cannot be easily generalized to this particular set of students at this time. Understanding the factors that influenced the students to choose Tourism Management at Champlain, St-Lambert and why they then leave before completing the six semesters will help with student success and with the marketing of the program. The theoretical framework guiding the study is metacognition, a branch of cognitive psychology that deals with the awareness and understanding of one’s thinking processes. Through a survey, students were asked to rank the general and specific factors that influenced their choice of Tourism Management as a program of study. Exit interviews were carried out with students who abandoned the program within the first year of study to determine the reasons for dropping out. Students who persisted in the program wrote journals describing their first year experience in order to identify any differences in metacognitive abilities with those who abandoned the program. The academic records of all students were also analyzed. The major factors influencing students to choose the Tourism Management program were interest in travel and job opportunities available after graduating. The results from the exit interviews and journals also showed that interest in travel was the primary reason for enrolment. The knowledge that students had of Cegep and the Tourism Management program before enroling however was negligible, particularly among the group that abandoned the program within the first year of study. The analyses of the academic records of the 2007 incoming students showed that the students with the lower high school grades were more likely to abandon the Tourism Management program than those with higher grades. The same is true for first semester and second semester Cegep grades. The major reason why the students abandoned the program during the 2007/2008 academic year was a lack of interest or a dislike of the program, followed by financial difficulties. It is not clear however what the lack of interest can be attributed to and this may be an avenue for future research. As opposed to the students who persisted in the program, those who abandoned their studies had unrealistic expectations of the academic requirements, were unprepared for the workload, had more difficulty analyzing their own performance and had not set concrete goals for themselves. The study shows several problem areas within the program. Of main concern is the lack of knowledge that students have of Cegep life and the Tourism Management program in general and the lack of preparation for Cegep level courses. The scheduling of courses and teaching methods within the program are other areas that need to be addressed. The paper concludes with a set of recommendations to possibly help remedy some of the problems.||Résumé : Ce travail s’intéresse aux facteurs qui motivent les étudiants à s’inscrire au programme de tourisme offert au Collège Champlain de St-Lambert. Il cherche à établir les raisons qui font en sorte qu’un si grand nombre d’étudiants abandonnent le programme avant d’obtenir leur DEC. Plusieurs recherches ont été effectuées sur l’abandon scolaire, mais il n’y a pas de consensus quant aux raisons pour lesquelles les étudiants se retirent du programme collégial. Actuellement, il est difficile d’établir des liens entre les résultats de ces recherches et ce groupe d’étudiants. La compréhension des facteurs qui influencent les étudiants à choisir le tourisme au Collège Champlain et les raisons qui font en sorte qu’ils quittent avant d’avoir complété leur formation, nous permettront d’améliorer le taux de rétention des étudiants dans ce programme. De plus, cela favorisera le marketing du programme. Le cadre théorique de cette recherche est la métacognition, une composante importante de la psychologie cognitive qui examine la connaissance et le contrôle qu’une personne a sur sa façon de penser. La métacognition est une variable qui différencie les étudiants qui réussissent de ceux qui abandonnent (Tardif 1997). La méthodologie de cette recherche comprend : un sondage, des entrevues, des comptes-rendus sous forme de journal et une analyse des résultats scolaires. Le sondage fut complété par tous les étudiants qui ont commencé le programme en tourisme en août 2007. Ce sondage avait pour but d’établir les facteurs qui ont motivé les étudiants à choisir cette discipline. Ceux-ci étaient divisés en deux volets soient : les facteurs généraux et les facteurs spécifiques. Les facteurs généraux comprennent l’intérêt pour les voyages et les informations obtenues auprès des orienteurs, des enseignants, de la publicité faite par les cégeps, des parents et des amis. Les facteurs spécifiques incluent les différents cours offerts tels que la géographie, l’informatique, l’administration, le programme de voyages, le stage en milieu de travail, la réputation du programme et de ses professeurs. Les entrevues ont été effectuées auprès de sept étudiants qui ont abandonné le programme entre décembre 2007 et juin 2008. Le but de ces entrevues était de déterminer les raisons de ces abandons. Les étudiants qui ont poursuivi leur formation en tourisme ont rédigé un journal dans lequel ils décrivaient leur expérience tout au long de leur première année d’études. Dans ce journal, ils devaient répondre à sept questions qui avaient pour but de déterminer les différences entre leurs habiletés métacognitives et celles de ceux qui se sont retirés du programme. L’analyse des dossiers des étudiants tenait compte des résultats scolaires du secondaire ainsi que des résultats académiques de la première année de cégep. Les principaux facteurs qui ont motivé les étudiants à choisir le programme gestion du tourisme étaient l’intérêt pour les voyages et les opportunités d’emploi après l’obtention de leur DEC. La connaissance que les étudiants ont du cégep et du programme de gestion du tourisme avant de s’inscrire était toutefois négligeable, particulièrement parmi le groupe qui a abandonné le programme durant la première année d’études. L’analyse des résultats académiques des étudiants a démontré que les candidats ayant des notes inférieures à l’école secondaire sont plus susceptibles d’abandonner le programme de gestion du tourisme que ceux ayant des notes supérieures. L’analyse arrive aux mêmes conclusions en ce qui concerne les candidats qui ont obtenu de faibles résultats académiques lors de la première et de la deuxième session du cégep. Les raisons principales qui ont fait en sorte que les étudiants ont abandonné le programme durant l’année académique 2007-2008 étaient le manque d’intérêt pour le programme et les difficultés financières. Par ailleurs, nous ne pouvons établir de façon générale les causes de ce manque d’intérêt. Cela pourrait faire l’objet d’une recherche ultérieure. Par opposition aux étudiants qui ont poursuivi le programme, ceux qui ont abandonné leurs études avaient des attentes irréalistes en ce qui a trait aux exigences académiques, ils n’étaient pas préparés pour la charge de travail, ils avaient plus de difficultés à analyser leur propre performance et ils ne s’étaient pas fixé d’objectifs concrets. L’étude a identifié plusieurs secteurs problématiques à l’intérieur du programme. L’une des problématiques principales est le manque de connaissance que les étudiants ont de la vie au cégep et du programme de tourisme en général sans compter le manque de préparation pour des cours de niveau cégep. L’horaire des cours et les méthodes d’enseignement à l’intérieur du programme sont d’autres éléments qui méritent d’être revus. Les limites de cette recherche comprennent le nombre restreint d’étudiants qui ont accepté d’être interviewés et l’effet d’intervieweur. Étant donné que l’intervieweur était le professeur des étudiants et malgré le fait que ceux-ci n’étudient plus en gestion du tourisme, ils peuvent se sentir obligés de répondre à l’intervieweur de façon subjective. Les recherches futures pourront inclure un plus grand nombre d’entrevues menées par des intervieweurs expérimentés n’ayant eu au préalable aucun contact avec les étudiants et ce dans le but de favoriser une plus grande objectivité. Un autre domaine de recherche pourrait être l’analyse du fait que des étudiants très intéressés par les voyages finissent par se désintéresser complètement du programme. Enfin et possiblement l’un des facteurs qui nous semble des plus importants est le besoin pour les étudiants du secondaire d’en connaître plus sur la vie au cégep et sur le programme de gestion du tourisme. Le document se termine par un ensemble de recommandations pour le Collège, le programme et les professeurs pour éventuellement aider à remédier aux problèmes identifiés.

Enormous amounts of pesticides are manufactured and used worldwide, some of which reach soils and aquatic systems. Glyphosate is a non-selective herbicide that is effective against all types of weeds and has been used for many years. It can therefore be found as a contaminant in water, and procedures are required for its removal. This work investigates the use of biopolymeric membranes prepared with chitosan (CS), alginate (AG), and a chitosan/alginate combination (CS/AG) for the adsorption of glyphosate present in water samples. The adsorption of glyphosate by the different membranes was investigated using the pseudo-first order and pseudo-second order kinetic models, as well as the Langmuir and Freundlich isotherm models. The membranes were characterized regarding membrane solubility, swelling, mechanical, chemical and morphological properties. The results of kinetics experiments showed that adsorption equilibrium was reached within 4 h and that the CS membrane presented the best adsorption (10.88 mg of glyphosate/g of membrane), followed by the CS/AG bilayer (8.70 mg of glyphosate/g of membrane). The AG membrane did not show any adsorption capacity for this herbicide. The pseudo-second order model provided good fits to the glyphosate adsorption data on CS and CS/AG membranes, with high correlation coefficient values. Glyphosate adsorption by the membranes could be fitted by the Freundlich isotherm model. There was a high affinity between glyphosate and the CS membrane and moderate affinity in the case of the CS/AG membrane. Physico-chemical characterization of the membranes showed low values of solubility in water, indicating that the membranes are stable and not soluble in water. The SEM and AFM analysis showed evidence of the presence of glyphosate on CS membranes and on chitosan face on CS/AG membranes. The results showed that the glyphosate herbicide can be adsorbed by chitosan membranes and the proposed membrane-based methodology was successfully used to treat a water sample contaminated with glyphosate. Biopolymer membranes therefore potentially offer a versatile method to eliminate agricultural chemicals from water supplies.

Angle Class III malocclusion has been a challenge for researchers concerning diagnosis, prognosis and treatment. It has a prevalence of 5% in the Brazilian population, and may have a genetic or environmental etiology. This malocclusion can be classified as dentoalveolar, skeletal or functional, which will determine the prognosis. Considering these topics, the aim of this study was to describe and discuss a clinical case with functional Class III malocclusion treated by a two-stage approach (interceptive and corrective), with a long-term follow-up. In this case, the patient was treated with a chincup and an Eschler arch, used simultaneously during 14 months, followed by corrective orthodontics. It should be noticed that, in this case, initial diagnosis at the centric relation allowed visualizing the anterior teeth in an edge-to-edge relationship, thereby favoring the prognosis. After completion of the treatment, the patient was followed for a 10-year period, and stability was observed. The clinical treatment results showed that it is possible to achieve favorable outcomes with early management in functional Class III malocclusion patients.

Purpose - The aim of this paper is to briefly present aspects of public brownfield management policies from Brazilian and German points of view. Design methodology approach - The data collection method combined literature and documental research. The bibliography included Brazilian and German literature about brownfield management. The documental research includes Brazilian and German legislation and official documents published by CETESB, the Environmental Company of the State of São Paulo, Brazil. Furthermore, publications of German governmental research institutions have been integrated in the paper. Findings - In Brazil, despite the lack of a federal public policy, the State of São Paulo has approved specific rules to deal with contaminated sites. Topics that could be targets of scientific studies have been identified. Experiences in Germany show that it is essential to have political will and cooperation between the different political levels and technical disciplines. Partnerships between German and Brazilian universities would be welcome as there is a wide range of opportunities for academic post-graduation studies and research focusing on human resources capacitation in environmental management. Originality value - The paper makes an original contribution of exploring an area (brownfield management) that is at the forefront of discussion in academe and industry

Information and knowledge are resources of environmental education (EE) that can be performed through knowledge management (KM). The aim of this paper is to propose measures of knowledge creation (KC) to improve performance of EE. This study is based on the research literature without empirical findings; therefore, the results are limited by the methodological resources of the theoretical essay. However, this limitation is the greatest motivation for future research which could investigate the proximity of EE with KM and KC in empirical investigations. Some suggestions for developing the requirements of KC programs to EE are presented as the results: possibility of the SECI process to better perform various aspects of environmental education such as social learning, interaction activities, dialogue, experience exchanging, information and knowledge, and of different ideas and ways of acting, done by EE and, finally, the possibility of Ba to develop a proper space for creation of new environmental knowledge. This article contains academic contributions to KM by providing greater discussion and understanding of KC; to EE when it allows a different view based on the work of information and knowledge about the processes of teaching, when contributing to social programs for EE, improving their practices and, consequently, contributing to an environmentally sustainable economic development.

The topic of environmental sustainability is generating increased concern among business executives, governments, consumers, and management scholars. As these stakeholders struggle with the challenges and opportunities presented by an array of environmental issues, HRM scholars and practitioners alike have been relatively slow to engage in the ongoing discussions and debates. Through this special issue on Green FIRM, we seek to stimulate the field of HRM to expand its role in the pursuit of environmentally sustainable business. In this introduction to the special issue, we first provide an overview of the articles that appear in the special issue. Next we present a detailed discussion of research questions that arise from a consideration of several functional HRM practices, including performance management; training, development, and learning; compensation and rewards; and organizational culture. We conclude by describing opportunities for research at the intersection of strategic HRM and environmental management. If pursued with vigor, research addressing this extensive agenda could begin to establish a healthy field of Green FIRM scholarship.

Understanding the product`s `end-of-life` is important to reduce the environmental impact of the products` final disposal. When the initial stages of product development consider end-of-life aspects, which can be established by ecodesign (a proactive approach of environmental management that aims to reduce the total environmental impact of products), it becomes easier to close the loop of materials. The `end-of-life` ecodesign methods generally include more than one `end-of-life` strategy. Since product complexity varies substantially, some components, systems or sub-systems are easier to be recycled, reused or remanufactured than others. Remanufacture is an effective way to maintain products in a closed-loop, reducing both environmental impacts and costs of the manufacturing processes. This paper presents some ecodesign methods focused on the integration of different `end-of-life` strategies, with special attention to remanufacturing, given its increasing importance in the international scenario to reduce the life cycle impacts of products.

The aim of this article is to present the main contributions of human resource management to develop sustainable organizations. The relationship between human resources and organizational sustainability, which is based on economical, social and environmental performance, involves some important aspects concerning management such as innovation, cultural diversity and the environment. The integration of items from the triple bottom line approach leads to developing a model based on a strategic and central posture of human resource management. Based on this model, propositions and recommendations for future research on this theme are presented.
