Sustainability management : insights from the viable system model

A review of current literature on sustainability standards reveals a significant gap between their adoption and the implementation of sustainability into every level of the organisation. In this paper, it is argued that in order to overcome this challenge, an appropriate model of an organisation is needed. The Viable System Model (VSM) is proposed as such a model and, in order to illustrate this argument, it is used to interpret the ISO 26000 standard on Social Responsibility (SR). First, the VSM theory is introduced and presented by modelling the hypothetical company Widget Co. Then, the clauses of ISO 26000 are mapped on the Widget Co. model, together with detailed descriptions and examples on the organisational and managerial implications of its adopting the standard's guidelines. The result is the identification of generic SR functions that need to be performed by the various organisational governance systems, as well as their dynamic interrelations, thus clarifying implementation issues. Moreover, by identifying different SR management layers, VSM is suggested as a way forward to develop an integration model for SR issues and respective sustainability tools. Finally, a discussion is given on the implications of using this approach to integrate sustainability standards and the way this research contributes to recent developments in sustainability research

Integrated sustainability management for organizations

Purpose – The purpose of this paper is to propose the Viable System Model (VSM) as an effective model to base the analysis of organizational sustainability (long-term viability). It is specifically proposed as a model to integrate the various sustainability tools, and as the basis for designing a unified Sustainability Management System. Design/methodology/approach – The VSM is used as an organizational model to examine three prominent sustainability standards: ISO 26000, ISO 14001 and ISO 14044. A generic manufacturing company is used as a template; and its typical business processes are related to each of the VSM’s components. Each clause of the three sustainability standards is then mapped on to the VSM model. These three models are integrated into one, by analysing the differences, similarities and complementarities in the context of each VSM component, and by identifying common invariant functions. Findings – In all, 12 generic sustainability functions are identified. ISO 26000 has the widest scope; ISO 14001 is focused primarily on internal measurement and control (System 3), while ISO 14044 is a complex performance indicator at the System 3 level. There is a general absence of System 2. Each standard can be regarded as a distinct management layer, which needs to be integrated with the Business Management layer. Research limitations/implications – Further research is needed to explore the specifics of integration. Practical implications – This integration should not be based on creating distinct roles for each management layer. Originality/value – The paper uses the insights of organizational cybernetics to examine prominent sustainability standards and advance sustainability management at the business level

Carbon Loss Pathways in Degraded Peatlands: New Insights From Radiocarbon Measurements of Peatland Waters

Peatland carbon stores are under widespread anthropogenic pressure, resulting in degradation and carbon loss. This paper presents DO14C (Dissolved Organic Carbon) dates from waters draining two eroded blanket peatland catchments in the UK. Both catchments are characterized by severe gully erosion but one additionally has extensive surface erosion on unvegetated surfaces. DO14C values ranged from 104.3 to 88.6 percent modern (present to 976 Before Present). The oldest DOC dates came from the catchment characterized by both gully and surface erosion and are among the oldest reported from waters draining temperate peatlands. Together with peat age-depth data from across the peatland landscape, the DO14C ages identify where in the peat profile carbon loss is occurring. Source depths were compared with modeled water table data indicating that in the catchment where gully erosion alone dominated, mean water table was a key control on depth of DOC production. In the system exhibiting both gully erosion and surface erosion, DOC ages were younger than expected from the age of surficial peats and measured water tables. This may indicate either that the old organic matter exposed at the surface by erosion is less labile or that there are modifications of hydrological flow pathways. Our data indicate that eroded peatlands are losing carbon from depth, and that erosion form may be a control on carbon loss. Our approach uses point measurements of DO14C to indicate DOC source depths and has the potential to act as an indicator of peatland function in degraded and restored systems

ETHNICITY AND RISK: THE CHARACTERISTICS OF POPULATIONS IN CENSUS WARDS CONTAINING MAJOR ACCIDENT HAZARDS IN ENGLAND AND WALES

Recent geographical and sociological research has focused on analysing the environmental equity and justice dimensions of the distribution of pollution and risk. In the US, where most of this research has taken place, studies have shown that ethnic minority and poor communities bear a disproportionate burden of environmental risk, leading to accusations of environmental racism and deliberate targeting of marginal communities in siting decisions. Little attention has been given to these issues in the UK. This paper reports on a preliminary study examining the ethnic characteristics of census wards containing a particular category of technological risk known as 'major accident hazards'. The ethnic characteristics of wards with and without major accident hazard sites are analysed at national and regional scales. This reveals some evidence of a disproportionate siting of major accident hazard sites in wards with higher Asian populations. However it is stressed that these results provide no more than a preliminary indication of a pattern of distribution to be investigated further and that there are a number of significant limitations with the analysis undertaken including the size of spatial unit utilised, the lack of differentiation between major accident hazard sites and the need to examine the relationship between ethnicity and other socio-economic variables. No definitive conclusions can be drawn at this stage as to the validity, significance or cause of the apparent bias in site locations

Approaching Freshet beneath Landfast Ice in Kugmallit Bay on the Canadian Arctic Shelf: Evidence from Sensor and Ground Truth Data

The Mackenzie River is the largest river in the North American Arctic. Its huge freshwater and sediment load impacts the Canadian Beaufort Shelf, transporting large quantities of sediment and associated organic carbon into the Arctic Ocean. The majority of this sediment transport occurs during the freshet peak flow season (May to June). Mackenzie River-Arctic Ocean coupling has been widely studied during open water seasons, but has rarely been investigated in shallow water under landfast ice in Kugmallit Bay with field-based surveys, except for those using remote sensing. We observed and measured sedimentation rates (51 g m-2 d-1) and the concentrations of chlorophyll a (mean 2.2 ?g L-1) and suspended particulate matter (8.5 mg L-1) and determined the sediment characteristics during early spring, before the breakup of landfast ice in Kugmallit Bay. We then compared these results with comparable data collected from the same site the previous summer. Comparison of organic quality in seston and trapped material demonstrated substantial seasonal differences. The subtle changes in biological and oceanographic variables beneath landfast ice that we measured using sensors and field sampling techniques suggest the onset of a spring melt occurring hundreds of kilometres farther south in the Mackenzie Basin.Le fleuve Mackenzie est le plus grand fleuve de l’Arctique nord-américain. Son énorme bassin d’eau douce et sa masse de sédiments ont des effets sur la plateforme externe de la mer de Beaufort canadienne, transportant ainsi de grandes quantités de sédiments et de carbone organique associé dans l’océan Arctique. La plus grande partie du transport des sédiments se produit pendant la saison haute d’écoulement du courant d’eau douce dans la mer (de mai à juin). Même si le couplage du fleuve Mackenzie et de l’océan Arctique a fait l’objet d’études approfondies durant les saisons d’eau libre, il a rarement été étudié en eau peu profonde sous la banquise de la baie Kugmallit au moyen d’études sur le terrain, sauf dans le cas d’études faisant appel à la télédétection. Nous avons observé et mesuré les taux de sédimentation (51 g m-2 d-1) et les concentrations de chlorophylle a (moyenne de 2,2 ?g L-1) et de matière particulaire en suspension (8,5 mg L-1), puis déterminé les caractéristiques des sédiments au début du printemps, avant la rupture de la banquise dans la baie Kugmallit. Ensuite, nous avons comparé ces résultats à des données comparables recueillies au même emplacement l’été précédent. La comparaison de la qualité organique du seston et des matières emprisonnées faisait ressortir d’importantes différences saisonnières. Les changements subtils sur le plan des variables biologiques et océanographiques sous la banquise que nous avons mesurés à l’aide de capteurs et de techniques d’échantillonnage sur le terrain laissent entrevoir un début de fonte du printemps se produisant à des centaines de kilomètres plus au sud, dans le bassin du Mackenzie

The Relationship Between Transformational Leadership, Leader Effectiveness, and Turnover Intentions: Do Subordinate Gender Differences Exist?

The aim of this study was to examine gender differences among subordinates in the strength of relationships between transformational leadership, leader effectiveness, and voluntary organizational turnover intentions. The authors drew from various theoretical bases, including transformational leadership theory, social role theory, and role congruity theory, to undergird the research. National Collegiate Athletic Association (NCAA) Division I male and female assistant coaches of women’s basketball, softball, and volleyball teams (N = 294) responded to the Multifactor Leadership Questionnaire (MLQ) and turnover intention questionnaire. Structural equation modeling (SEM) revealed a noteworthy gender difference in the strength of relationship between leader effectiveness and voluntary organizational turnover intentions. Contributions and implications are discussed

Effects of thermal and moisture cycling on the internal structure of stitched RTM laminates

Conventional aerospace composites are strong and stiff in the directions parallel to the carbon fibers, but they are prone to delaminations and damage in the through-the-thickness directions. Recent research has shown that substantial improvements in damage tolerance are obtained from textile composites with Z-direction reinforcement provided by stitching, weaving, or braiding. Because of the mismatch in thermal and moisture expansion properties of the various material components, there is a potential for microcracks to develop in the resin matrix. These cracks can form to relieve the mechanical stresses that are generated during curing or in-service temperature cycles

Which Phish Get Caught? An Exploratory Study of Individual Susceptibility to Phishing

The use of the Internet and networking technologies continues to rise. Alongside the benefits that are derived from the use of these technologies, numerous threats continue to emerge. This study examines several variables within the message characteristics, personality traits and Internet-related experience to determine an individual\u27s susceptibility for phishing attacks. The results of an ethical phishing experiment show that message characteristics and Internet-related variables are better predictors of whether an individual will be more susceptible to phishing attacks

Chemical and Biological Monitoring of a Constructed Wetland on Jones Branch Treating Acid Mine Drainage

Acid mine drainage (AMD) from an abandoned underground coal mine in the Jones Branch watershed in McCreary County, KY, substantially reduced water quality in Jones Branch. Downstream from the mine seeps, the pH was routinely below 4.5 and concentrations of most heavy metals, especially iron, were elevated. A cattail wetland (1,022 m2) was constructed on Jones Branch in 1988-1989 to obviate the effects of the AMD. Monthly chemical monitoring was performed on the water from above, from below, from the inlet and outlet of the wetland, and from the 25 cells within the wetland. Based on chemical monitoring, the wetland initially improved water quality, increasing the pH and removing substantial amounts of heavy metals. Beginning in the winter of 1991, water quality at the wetland outlet began to decline, but was above levels reported for most contaminants prior to construction. To augment the chemical monitoring, a biomonitoring study was initiated in the spring of 1990. Acute 48-hr static tests were conducted with newly hatched fathead minnows (Pimephales promelas). Water samples were obtained from the seep inlet, four cells within the wetland, and from Jones Branch above and below the wetland site. Median lethal concentration (LC50) values determined monthly reflect the decline in water quality at the outlet over time. However, within the wetland there was gradual improvement in survivability from inlet to outlet, providing evidence that the wetland was responsible for a modest improvement in water quality. Although there was modest overall improvement in the water quality of Jones Branch due to wetland treatment, additional remediation will be required before the stream can support vertebrate organisms
