Adapting the environmentallysustainable logistics performancemanagement process

Persdotter Isaksson, Maria January 2018 (has links)
Process based approaches to environmentally sustainable logistics performancemanagement are lacking within organizations that buy logistics services (buyers) and thatsell logistics services (LSPs), which puts a damper on environmentally sustainablelogistics performance. Organizations understand the potential of environmentallysustainable logistics performance management, but they seems unable to developeffective management processes and accurate environmentally sustainable logisticsmetrics. An environmentally sustainable logistics performance management process(ESLPM process) is one way for an organization to manage its performance in line withits environmental strategy and overall environmental targets.The purpose of this thesis is to adapt the logistics performance management process toinclude environmental sustainability. The first research question is about thecharacteristics for including environmentally sustainable logistics in the logisticsperformance management process. Characteristics that need to be included in the logisticsperformance management process must be identified in order to illustrate the process, inorder to improve the environmental performance. Moreover, by identifying thecharacteristics of the process activities, it is possible to compare how the characteristicsof the process are similar and/or different between organizations. The performancemanagement process can only be used successfully if the strategy is closely aligned tosome process activities being implemented; this motivates the second research question,which is how the ESLPM process can be expanded to measure alignment.The method used to collect empirical data is primarily interviews in eight multiple-casestudies of four organizations buying logistics services and four organizations sellinglogistics services. The frame of reference is based on the inclusion of environmentalsustainability characteristics in the logistics performance management process and thealignment between process and strategy as well as within processes. The results include a description of an ESLPM process that contains five activities withseventeen characteristics for managing environmentally sustainable logistics. Specificcontexts of eight organizations, like type (private, public, or private/public) and size(small, medium, or large) and their influence and implications concerning the ESLPMprocess are discussed and presented. The matching between the theoretical ESLPMprocess (based on the frame of reference) and the empirical ESLPM process is presentedand then compared within the eight organizations, resulting in a modified ESLPM processwith twenty characteristics. The results shows that the use of an ESLPM process is stillin beginning stages and is not done in a structured manner; in particular, the organizationsfind it difficult to establish appropriate ESLP metrics, to define the ESLP metrics, to setaccurate ESLP targets, and to collect and measure the ESLP metrics.Results from measuring level of alignment include theoretical measurement models fortwo types of alignment, a model for measuring alignment between process and strategy,as well as a model for measuring alignment within a process. The two theoretical modelscontain different aspects that measure alignment on three different levels (high, medium,low). These models are tested within each organization, and the results from measuringlevel of alignment per organization is used to evaluate the two theoretical models,resulting in modified models for measuring alignment.The results lead to increased understanding of how type and size influence thecharacteristics of the ESLPM process and the level of alignment. The results also contribute to the literature on environmentally sustainable logistics performancemanagement and the alignment both between process and strategy as well as within theESLPM process. The result can be used by organizations selling and buying logisticsservices to improve their environmentally sustainable logistics performance.

Um estudo sobre o comportamento do consumidor ambientalmente favorável: uma verificação na região do ABC paulista / A study of the consumer behavior under the environmentally favorable standpoint: an application in the São Paulo State ABC Region.

Romeiro, Maria do Carmo 07 December 2006 (has links)
A presente tese teve como objetivo identificar fatores que influenciam o comportamento de consumo ambientalmente mais favorável e, a partir desse processo, evidenciar subsídios às decisões de marketing social voltado para a adoção desse comportamento. Para atender a esse objetivo, buscou-se organizar o referencial teórico inicialmente com um entendimento sobre o relacionamento entre marketing societal e marketing social, passando pelas aplicações de marketing verde e de marketing de idéias. Na seqüência, esse referencial incorporou aspectos teóricos que envolvem o comportamento do consumidor, bem como estudos aplicados à verificação desse comportamento sob a ótica ambiental. A análise exploratória realizada a partir desse referencial teórico-empírico evidenciou a presença de distintas dimensões comportamentais dentro do construto do comportamento de consumo ambientalmente favorável, além das conclusões controversas envolvendo vários fatores de influência sobre essas dimensões comportamentais, o que deu encaminhamento para a realização de uma pesquisa de campo que contribuísse para a identificação dos fatores com influência comum nessas dimensões comportamentais. O modelo de pesquisa de campo foi de caráter descritivo, utilizando o método quantitativo por levantamento amostral junto a 509 consumidores responsáveis pelas compras do domicílio, com idade a partir de dezoito anos, residentes na Região do ABC Paulista. Os resultados gerados, a partir da utilização da técnica de análise multivariada denominada General Linear Models (GLM), mostraram três fatores de influência comum estatisticamente significante sobre as dimensões comportamentais ambientalmente mais favoráveis (interesse ambiental, inconveniência de ser ambientalmente amigável e grau de comprometimento ambiental), do conjunto de vinte e um fatores integrados ao modelo, além de outros seis descartados durante o processo de estruturação desse modelo. Esse resultado, acrescido de orientações provenientes da análise exploratória, sugeriu o desenho de um modelo de comportamento de consumo ambientalmente favorável, cuja aplicação poderá ser implementada em novos estudos, bem como um conjunto de subsídios às decisões do composto de marketing social voltado para a adoção do comportamento ambientalmente mais favorável. / This current work has the purpose of identifying factors that influence the most environmentally favorable consumer behavior and, from this process on, evidence support to social marketing decisions oriented to the adoption of such behavior. In order to understand such purpose, an organization of the theoretical references was sought, initially trying to understand the relationship between societal marketing and social marketing, moving on to green marketing applications and the marketing of ideas. After that, these references incorporated theoretical aspects that involve consumer behavior, as well as studies applied to the verification of such behavior under the environmental standpoint. The exploratory analysis carried out after this empirical theoretical set of references evidenced the presence of distinct behavioral dimensions inside the environmentally favorable consumer behavior. Besides that, the controversial conclusions involving several influence factors regarding these behavioral dimensions, led to the performance of a field research that contributed with the identification of factors that bear common influence in those behavioral dimensions. The adopted research model was the one of descriptive character, using the quantitative method by sampling 509 consumers responsible for their household purchases, aged over eighteen, resident in the São Paulo State ABC Region. The generated results, after the use of the multivaried analysis called General Linear Models (GLM), showed three factors of statistically significant common influence over the most environmentally favorable behavioral dimensions (environmental interest, inconvenience of being environmentally friendly and degree of environmental commitment), out of a set of twenty-one factors integrated to the model, besides six others turned down during this model structuring process. This result, added with orientations from the exploratory analysis suggested the drawing of a environmentally favorable consumer behavior model, whose application may be implemented in new studies, as well as a set of inputs to social marketing decisions made in order to adopt the environmentally favorable behavior.

Energy use by individual office workers : psychological and contextual influences on behaviour

Littleford, Clare January 2013 (has links)
Research into energy demand in office buildings has tended to focus on building fabric or systems, or the organisation as a whole, rather than the actions or motivations of individual building occupants. This study applies an attitude-behaviour approach used more frequently with household or travel behaviours to energy demand behaviours by individual occupants in office settings. The approach is extended to include contextual factors such as behavioural control, organisational expectations and social influences. Comparisons are drawn between the office and home settings. The study took place in the offices of two local authorities, Nottingham City Council and Nottinghamshire County Council, and included a questionnaire survey (n=819), semi-structured interviews (n=9), and building surveys (n=5). Behaviours examined included switching off lights, computers and computer monitors. Lighting behaviours were reported to be carried out more frequently than computer monitor behaviours in both the office and household settings. Analysis of behaviours identified that they needed to be considered at a specific level, according to the equipment (lighting, computer monitors), setting (office, home), and triggers (finishing a task, leaving a room). The physical context of the behaviour was particularly important. Different levels of individual control over energy affected the performance of behaviours. No evidence was found to support the notion of spillover that enacting one energy demand behaviour might lead to the enactment of further energy demand behaviours, including for similar behaviours performed in different settings (e.g. the office and the home). Organisational, social and psychological/attitudinal influences on individual behaviour were also examined. Structural Equation Modelling examined influences proposed by the Theory of Planned Behaviour and Values-Beliefs-Norms Theory. Neither theory provided a strong explanation of the collected data. However, support was found for the Perceived Behavioural Control construct, while moral and value-led constructs had a small influence on behaviour. This thesis provides recommendations for practitioners and policy makers seeking to reduce individual-level energy demand in office settings, and for future research into energy use in organisational settings. Recommendations include promoting energy saving as an aspect of professionalism, characterising energy demand behaviours specifically by setting and equipment, and recognising the importance of the social aspects of shared office environments.

Representations of Environmentally Displaced People In Canadian Print Media

Stumpf, Bianca 23 September 2019 (has links)
Context: This thesis analyzes media coverage in Canada of environmentally displaced people (EDP) due to their recent prominence in political discussions on a national and international level as well as in the literature. Objectives: This thesis has three goals, notably (1) to raise awareness of EDP as a social phenomenon; (2) to understand how EDP are currently constructed in the public sphere; and (3) to analyze whether Canadian media characterizes EDP within discourses of victimization and/or devictimization. Ultimately, this thesis investigates: How does Canadian print media represent environmentally displaced people? Methodology: A total of 149 (132 English and 17 French) Canadian news articles, appearing from 2000 to 2017, were selected for analysis through a search strategy that included specific key words. The articles selected appeared in the Toronto Star, Globe & Mail, Montreal Gazette, Ottawa Citizen, Vancouver Sun, Le Journal de Québec, La Presse, and Canada Newswire. Results: The results were analyzed by using a frame analysis. Based on this analysis, a few key points were commonly used to represent EDP, including the uncertainty over which terms to use, their quantification, as well as a scare tactic to entice action towards climate change. Overall, the media tended to portray EDP using themes of devictimization. Conclusion: Future research should be conducted to continue to analyze media representations of those displaced. It is also imperative to collect more data on EDP in order to resolve the debate around their definition and officially recognize one term to help facilitate research and increase the legitimacy of those displaced - whether they are recognized as migrants or refugees.

The Effects Of Moisture On Thin Film Delamination And Adhesion

Waters, Patrick 28 March 2005 (has links)
Significant drops in adhesion have been measured for copper and diamond like carbon (DLC) films with the introduction of water at the film/substrate interface. A 1 thick tungsten superlayer with high compressive residual stress was deposited on the films of interest to help induce interfacial debonding by indentation. Modifications were made to the superlayer indentation technique to introduce water at the interface while performing indents. Film adhesion dropped by a factor of 10 to 20 for the copper films and 50 to 60 for the DLC films. The reduction in adhesion is believed to be caused by a combination of lowering surface energy and a chemical reaction at the crack tip. When the film compressive residual stress is at least 4 times the critical buckling stress of a debonded film, telephone cord delaminations morphology can be observed. Delamination propagation has been induced in the past by applying a mechanical force to the film and similar results have been observed with the introduction of water. Crack propagation rates of 2 to 3 microns per second were measured for the DLC films with the introduction of water at the film/substrate interface. Telephone cord delaminations show potential for future use as microchannels in microfluidic devices and have shown excellent stability when manipulated with a microprobe to control fluid transport.

Viability of Bismuth as a Green Substitute for Lead in Jacketed .357 Magnum Revolver Bullets

Jenkins, Joel A. 11 March 2015 (has links)
In seeking to develop environmentally friendly lead-free non-toxic bullets, the research ballistically evaluated the performance of copper-jacketed handgun bullets containing a pure bismuth core. The lead was first removed from 140 grain HornadyTM XTP® bullets of 38 caliber (.357 diameter) by melting. The empty jackets were then refilled with pure bismuth, including the forming of a correctly sized hollow-point cavity. Due to the lower density of bismuth as compared to lead, the bismuth-cored bullets consistently weighed 125 gains. Conveniently this allowed direct comparison to commercially available 125 grain HornadyTM XTP® lead-cored bullets of 38 caliber. Both bismuth-cored and lead-cored versions of the 125 grain bullets had identical nose dimensions and jacket material, the only dimensional difference being the bullet length below the cannelure. Shooting took place at an outdoor range using a 357 Magnum RugerTM SP101® revolver with 3" barrel as the test weapon. FBI protocols were followed when firing through clothing, wallboard, plywood, steel plates and laminated glass. Wound paths and bullets were captured in ballistic gelatin, with data collected for velocity, penetration, expansion, and weight retention. Bismuth compared favorably with lead in all but the laminated glass test, where it under penetrated due to jacket separation.

Investigation of a Consumer's Purchase Intention and Behavior towards Environmentally Friendly Grocery Packaging

Oliver, Mikah Omari 08 1900 (has links)
This study adapted the theory of planned behavior to investigate the relationship between purchase intention and purchasing behavior toward environmentally-friendly grocery packaging. This quantitative study collected 487 useable responses on the Amazon Mturk platform targeting a population of US consumers over 18 years old who purchase groceries. Using the collected data, a correlation and regression analysis was conducted. The socio-demographic variables were used as moderators to investigate the relationship between purchasing intention and actual behavior. The study's results suggest that a consumer's subjective norms substantially stimulate environmentally friendly grocery packaging purchase intentions, which further has or leads to the most decisive influence on actual behavior. Second, we discovered that purchase intention and perceived behavioral control are likely working in conjunction to help bridge the intention-behavior gap in environmentally friendly consumption. Third, this study supplied a fresh perspective on socio-demographics' role in environmentally friendly consumption, confirming that predominantly younger, unmarried consumers are likelier to act upon their intentions by purchasing environmentally friendly grocery packaging. Furthermore, conclusions from this study uncover the primary influences of consumer purchase intention and behavior towards environmentally-friendly grocery packaging. Lastly, but not less important, this study identifies the barriers to environmentally friendly consumption's intention and behavior gap. Results can also give government agencies and brands a clearer perspective to make consumers more knowledgeable on environmentally friendly packaging consumption.

Boundaries for use in wheat variety classification use in Australia

Williams, Richard Malcolm January 2006 (has links)
Suppliers of wheat must ensure that their products have the required quality profile demanded by customers and consistently deliver that quality in order to be competitive. Australia’s wheat industry is highly exposed to such competitive threats because it relies heavily on exports. An integral component in maintaining Australia’s competitiveness has been its classification system. The first step involves the complex process of determining a genotypic quality profile of each variety – a variety classification. At harvest, subsequent steps are the use of a statutory declaration and testing of physical quality traits. Together these steps determine how deliveries of wheat are segregated. A single variety can have different classifications across the 7 classification regions of Australia. Most classification regions are divided along state borders and these are not reflective of potential environmental influences. / The manner in which Australia wheat breeding programs now tackle their task has changed since 1999. The commercially focused companies of the current era have national targets to remain viable, and are focused on costs. Other evolutions associated with the change, are the introduction of different sources of parental material, and moving to more economic composite quality testing regimes instead of the individual site by site testing used in the past. Together, these factors, particularly variety adaptability and stability of performance, have the capacity to increase variability. The likelihood of variation is further increased given that the current classification regions upon which classification decisions are made do not adequately reflect environmental effects on the expression of quality. To determine whether better divisions of the Australian wheat-belt could be identified for variety classification purposes, a substantial spatial and temporal database of historical quality results was assembled. The creation of this relational database was unique, because never before had expansive sets of independent, state-based, quality sub-sets been joined together. However, the data were unbalanced and required alternative statistical tools to be analysed. The relational database was the platform from which three phases of research were conducted. / The first research phase investigated the extent of cross over, or re-ranking of results, statistically referred to as genotype x environment interaction. The approach was to assess balanced data sets, in a manner reminiscent of the most common method identified from the literature. The results of those analyses showed that the size of genotype and environment interaction was small compared with the main effects of genotype and environment. The second phase of research focused on identifying alternative boundaries for classification purposes. Test divisions were compared with the current set of 7 classification regions for the capacity to minimise environmental variance while maintaining differences between the zones of a set. Test divisions were based on fourteen published divisions of the Australian wheat-belt. Analyses were conducting using residual maximum likelihood because of the unbalanced structure of the data. Estimates of variance components, quality trait means and standard errors were calculated. Consideration of such estimates resulted in the identification of 4 different divisions of the wheat-belt that had low environmental variance levels for important quality traits such as maximum resistance, dough development time, and water absorption. / In addition, these 4 divisions of the wheat-belt had fewer number of zones compared with the existing set of classification regions because they linked separate parts of the wheat-belt together. In order of decreasing merit, the 4 divisions of the wheat-belt represented average October maximum temperatures; agro-ecological zones reported by Williams et al. (2002); average annual rainfall; and Departments of Agriculture recommendation zones. A final phase of crosschecking was performed to assess the veracity of the 4 identified divisions. A cluster analysis supported the orientation of their boundaries and it was also observed that the use of fixed boundaries for classification purposes would not be negatively affected by seasonal variation. The 4 divisions of the wheat-belt identified in this research support the use of environmentally focused classification boundaries. In addition to improving the capacity to segregate consistent quality, the linking of geographically separate production areas of the wheat-belt reduced the number of zones and this offers process efficiencies.

The association between air pollution and lung cancer in the north west of Adelaide: a case control study and air quality monitoring.

Whitrow, Melissa Jayne January 2004 (has links)
Some suburbs within North West (NW) metropolitan Adelaide have lung cancer mortality up to twice that expected from state averages. Previous international research investigating high lung cancer rates in similar shared industrial and residential areas have had inconsistent results. This case control study was conducted to determine whether residential exposure to industry is a risk factor for lung cancer in NW Adelaide. Contemporary ambient air monitoring was undertaken as an indicator of future respiratory health risk. 142 lung cancer patients and 415 age, gender matched population controls were interviewed utilising an event history calendar. Lifetime exposure indices were calculated for cigarette smoking, passive smoking, occupation, air pollution (residential proximity to industry) and hobbies. Data was analysed utilising chi- quared and conditional logistic regression. Ambient carcinogens and fine particulates with potential industrial sources in the region were monitored in five locations. In the final multivariate model leaving school early, pack- years of cigarettes and not living in close proximity to the power station or light industrial area were statistically significant risk factors for lung cancer. A composite score of residential exposure to all industries was not significant. However cautious interpretation is required as it was noted participating controls resided significantly closer to industry than non-participants. Average concentrations of ambient carcinogens were within guidelines; however diesel exhaust particulate and Polycyclic Aromatic Hydrocarbons were elevated at sites in proximity to heavy vehicle traffic. Diurnal variations in PM[subscript 2.5] included weather and traffic-related short term peaks, and other peaks potentially related to industrial activity. Cigarette smoking is likely to be the primary cause of elevated lung cancer mortality in suburbs of NW Adelaide. The negative effect of residential exposure to two industries may be due to participation bias. Whilst having more thorough exposure assessment than previous research, this study may have been limited by low participation rates in cases and controls. Air monitoring data suggests there is not a significant public health risk at present; however these results are unlikely to be indicative of historical exposures. Future public health initiatives to curb high lung cancer mortality in the NW should focus on smoking prevention and reduction strategies. / Thesis (Ph.D.)--Department of Medicine and Department of Public Health, 2004.

Towards sustainable renovation : three research projects

Botta, Marina January 2005 (has links)
The focus of this dissertation is on existing housing areas: in industrialised western countries, in 2005, the number of existing buildings that are taken care of, maintained, repaired, renovated or restructured for other functions is higher than the number of buildings that are (new) built. This is a review dissertation, based on empirical material and further reflections from previous research projects dealing with Swedish housing renovation: private-owned old single-family housing areas and large housing areas from the 1950s, 60s and 70s, mainly owned by housing companies. The concepts of careful renovation, environmentally-friendly renovation and sustainable renovation are analysed as different approaches to housing renovation. The aim is to present an interpretation of sustainable renovation that includes the goals both of careful renovation and of environmentally-friendly renovation as necessary components of sustainable development. This dissertation identifies and analyses the main issues that may be faced during renovation and that have a relevant impact on the environment, the architecture or the inhabitants, and describes the renovation actions that have been used in the studied projects. It concludes with reflections about positive results, incongruities and challenges that may be found in projects of sustainable renovation. / QC 20100928
