Improving sustainable supply chain performance through organisational culture: A competing values framework approach

This research adopts the institutional and relational view theories to empirically test the impact of organisational culture (OC) on sustainable supply chain performance (SSCP) and further examines the impact of external integration on their relationship, drawing on a study in the food manufacturing industries in the UK and Greece. Using the mixed method approach, structural equation modelling (SEM) technique was first used to empirically analyse the data from a survey of 315 firms. In addition, insights from 11 interviews from top managers were qualitatively used as the basis to enrich and confirm the findings from the quantitative study. Our findings revealed that in the context of global supply chains only developmental, hierarchical, and group culture components of the competing values framework (CVF) as a model for assessing OC are conducive for achieving a higher SSCP. Although developmental, hierarchical and group cultures are instrumental for SSCP, a strong external integration is still required. Thus, external integration was found to mediate the relationship between the dimensions of OC and SSCP. The results further confirmed a positive relationship between all the dimensions of OC (developmental, group, hierarchical and rational culture) and external integration and a positive impact of external integration on SSCP. This research expands the institutional and relational view theories to examine the effect of OC (using CVF) on SSCP and further reveals the extent of external integration needed in the relationship to enhance SSCP in global supply chains. Supply chain managers are encouraged to adopt integrated competing values, namely, developmental, group, and hierarchical cultures to intensify the external integration in the supply chain to overcome several sustainability challenges and improve SSCP.     

An ecological economic simulation model for assessing fire and grazing management effects on mesquite rangelands in Texas

In the southern Great Plains of North America, fire exclusion has contributed to many rangelands converting from native grassland to woody shrublands dominated by mesquite (Prosopis glandulosa Torr.) and cactus (Opuntia spp.), threatening ecosystem health and human livelihoods in the region. Prescribed fire is the least expensive method of treating mesquite and other undesirable plants, but its role is as a maintenance treatment to prolong the life of more expensive brush control treatments. Using a simulation model of a hypothetical 1000 ha ranch, we evaluate the biological and economic implications of management scenarios involving the regular application of summer fire to reduce mesquite and cactus over a 30-year time period. We compared the model output with experimental data to corroborate model output before evaluating various management scenarios over a range of stocking rates. Scenarios included (a) varying initial range condition, (b) different frequencies of summer burning, and (c) different initial amounts of mesquite brush. Model simulations corroborated field data sufficiently well to give confidence in the output of the model. In our simulations the option of not treating to reduce brush and cactus had a major negative impact on range condition, secondary productivity and profitability. In contrast, all simulated fire treatments improved range condition, productivity and profitability except when initial range condition was poor. Initial range condition and stocking rate were the major factors affecting both productivity and profitability. Compared to other factors over which managers have short-term control, frequency of burning and the initial amount of mesquite cover, had a relatively minor impact. Simulations indicated that the highest level of profit consistent with maintaining or improving range condition was attained when individual animal production was 92-95% that of the maximum production per animal, a situation invariably associated with relatively low stocking rates.     

Maximising sustainability of Dutch dairy farming systems for different stakeholders: A modelling approach

A multi-attribute sustainability function is included into a dairy farm LP-model by using Weighted Goal Programming. The created Weighted Linear Goal Programming (WLGP)-model is used to maximise sustainability of different Dutch dairy farming systems and to analyse the impact of: (1) maximisation of individual sustainability aspects (economic, social and ecological sustainability) and (2) maximisation of overall sustainability using stakeholder preferences. Maximising the individual aspects of both dairy farming systems, i.e. conventional and organic, shows the trade-offs between different aspects of sustainability. For conventional as well as organic dairy farming maximum scores are highest for external social sustainability. The conventional dairy farm achieves a slightly higher score for overall sustainability than the organic dairy farm for all stakeholders (i.e. consumers and producers). This shows that it is possible for conventional dairy farms, similar to the conventional farm used in the analysis especially regarding the stocking density and under Dutch policy conditions, to achieve equal sustainability scores in comparison with organic dairy farms. It is concluded that the WLGP model is a suitable tool to analyse the sustainability of different dairy farming systems.     

Conceptual niche management of grassroots innovation for sustainability: The case of body disposal practices in the UK

The grassroots has recently been identified as an alternative site for the development of innovations that may contribute to shifts towards more sustainable systems of consumption and production. While the characteristics of these innovations have been elaborated, it remains unclear how these alternative ideas and practices can be purposively supported to populate incumbent systems. This is especially so in light of the difficulty the grassroots face in connecting forcefully with the mainstream.This article will address this issue by outlining an adaptation of conceptual niche management - an approach that focuses on the embedding of guiding principles used to fulfill basic societal needs - that is sensitive to grassroots innovation. The framework will be applied to the current UK body disposal system to illustrate how such transformative sustainability ideas may be capitalised on.     

Dynamic multidimensional assessment of sustainability at the macro level: The case of Austria

This paper explores the issue of sustainability at the macro scale employing multi-criteria decision aid (MCDA) methods. The incommensurability of values and the essentially multi-dimensional and dynamic nature of sustainability challenge the use of composite measurement indices. This determined the choice of MCDA methods. Austria was chosen as a case study, due to the wide availability of data, especially on indicators of strong sustainability. The structure of the multi-criteria problem comprised the evolution of different sustainability dimensions over time. The process for selecting criteria included a critical assessment of institutional sustainability agendas (UN, EU and Austrian Government) and theoretical recommendations.After an assessment of MCDA methods, the NAIADE method demonstrated the most suitable properties for sustainability assessment. The application of this outranking approach was undertaken in three separate settings: long-term from 1960 to 2003, medium-term, 1970-1995, and short-term, 1995-2003 with varying numbers of criteria. The response of results to the addition of evaluating criteria and periods was tested. The degree of credibility for accepting preference relations was also employed for sensitivity analysis.According to the results of long-term and medium-term assessments, especially in the weak sustainability setting, sustainable progress is taking place in Austria. In the short term, in the stronger sustainability setting and, especially as the number of criteria increases, more incomparable periods appear and trends are less determined. Moreover, it is shown how results crucially depend on the methodological choices.This is one of the first applications of the multi-criteria tools to the dynamic analysis of sustainability at the macro scale.

在构建了描述商品贸易收支差额和价值量比重的两个标准化指标NB和NV之后,本文首先在全部商品的基础上对中美贸易结构的稳定性进行分析,只发现了有限的稳定性;然后,从产品周期角度研究中美贸易格局中存在的动态性,分析了三个基点前后具有产品周期性的商品的变动趋势,结果表明由产品周期引起的动态性明显存在,而且从20世纪90年代开始显著增加,可以用来解释中国对美国形成的巨额贸易顺差;除此之外,还发现产品周期性具有从低技术向中技术再向高技术逐渐升级的趋势。     

The impact of material and immaterial sustainability on firm performance: The moderating role of franchising strategy

CSR and sustainability engagement is growing rapidly with ever-increasing attention. Accordingly, restaurant stakeholders now demand restaurant companies to disclose relevant ESG information (i.e., materiality) to analyze risks and opportunities that ESG factors bring to firms over the long term. As established in stakeholder theory, restaurant materiality is shaped by a firm's key stakeholders and also by the industry's distinguishing factor, franchising. However, despite their importance and timeliness, materiality and franchising remain largely absent from scholarly discussion in the field of tourism and hospitality. Using a novel industry-specific materiality classification of sustainability initiatives, here we show that franchising positively moderates the impact of investing in immaterial sustainability on firm performance. The results provide early empirical validation of stakeholder theory in relation to restaurant materiality and franchising, and show the impact of allocating a firm's resources to material and immaterial sustainability issues on firm performance in the restaurant context.     

Sustainability and visitor management in tourist historic cities: the case of Santiago de Compostela,Spain

Tourism has a leading role in heritage cities and this implies a major challenge. The overall objective of this paper is to evaluate the performance of tourism planning and management with the view of achieving sustainable tourism in the historic center of Santiago de Compostela, Spain. The study addresses topics collected during a long research process of more than 10 years, such as strategic tourism plans, the implementation of quality management systems for tourism, the tourist supply and the regulation of flows. The results show a destination that has introduced alternatives to improve the tourism experience and diversify its offer beyond the Camino de Santiago. There is also growing concern in promoting the sustainability of the historic center. From our point of view, the strengthening of synergies between the different agents involved in the tourism sector of the city has been a key factor in dealing with this situation. However, in this sense, the main problem which is decongesting the tourist flows to the cathedral and its surroundings is still unresolved.
