Knowledge produced by environmental scientists is often inaccessible, intractable, or otherwise in need of reconfiguration for use in environmental regulation. Similarly, policy knowledge undergoes decontextualization in its address to the community of researchers and data curators whose findings are fundamental to its operation. This paper addresses the development of the total maximum daily load (TMDL) measurement as a means of decontextualizing both scientific and regulatory processes to render the practical results of those processes available as a means of collaboration, coordination, and development of watershed management and regulation. The TMDL measurement serves as a specific type of boundary object, a provisional boundary figure. A provisional boundary figure is a complex, model-derived system that is not fixed but rather an object of ongoing work that enables coordination between policy and research. Thus, the TMDL is deployed to explore the relationship between environmental management and the knowledge workers that enable and support it.

The Relationship

The present study aims to determine the impact of green innovation (GI) on the overall performance of an organization while keeping the variable of environmental management (EM) as a moderator. We used a dataset consisting of four data years, from 2014 to 2017, of A-share companies listed on the Shanghai Stock Exchange (SSE). The concept of green innovation refers to the use of advancements in technology that enable savings in energy, along with the recycling of waste material. When advanced technology is utilized in the production process, the products are referred to as green products and the whole process of adopting such technologies and product design is referred to as “Corporate Environmental Management”. Such innovations improve the overall financial performance of companies as it enables them to improve their social image by reducing their carbon footprint and ensures their long-term sustainability. The main issue is the limited focus and attention given to the topic, from the perspective of companies. This research focuses on the impact of green innovation and the importance of environmental management for the sustainability of companies. Our findings suggest that the relationship between green innovation and the performance of the company is positive and verifies the existence of moderating effects of environmental management on the relationship between green innovation and firm performance. Implications are given to academia and practitioners.

The use of unit area loading approaches to address the requirements of the US Clean Water Act (CWA) and the EU Water Framework Directive (WFD) to identify and manage diffuse urban pollution sources is outlined. Issues relating to traditional volume-concentration probabilistic modelling are highlighted and the robustness of total maximum daily load (TMDL) approaches is discussed. A hazard assessment methodology for catchment scale identification of source area pollutant loadings and receiving water ecological impacts is developed based on urban land use activities.

Purpose This study aims to examine the relationship between environmental cost (EC) on organisational performance (OPM) through an environmental management system (EMS) as the mediating variable. Design/methodology/approach A total of 2,600 manufacturers were identified and consequently selected as the entire study population. Additionally, this study used the structural equation modelling technique to identify the mediator effects of EMS between EC and OPM. Findings The EC and EMS relationship on OPM produced direct and indirect consequences. Hence, it is concluded that manufacturing industry in Malaysia are focused on the OPM when implementing EC and EMS. Originality/value The model would incorporate EC and EMS implementation on OPM in the Malaysian manufacturing industry. This study could also be advantageous to the industry in improving EC, EMS and OPM.

Introduction: Silent cerebrovascular infarcts resulting from vascular disease can manifest as a decline in cognitive function. These silent events are also associated with increased risk of clinically overt stroke. Arterial stiffness is a marker that represents atherosclerotic progression and is a predictor of cardiovascular events and mortality. This study examined the relationship between arterial stiffness and cognitive impairment between adults aged 50-80 years old with and without stroke. Hypothesis: We hypothesized that elevated arterial stiffness would be observed in individuals with stroke, and also be associated with increased cognitive impairment across all participants. Methods: Cognition was assessed using the Montreal Cognitive Assessment (MoCA). Arterial stiffness was quantified using carotid-femoral pulse wave velocity (cfPWV, in m/s), calculated as cfPWV=D/Δt, where D was the distance measured between arterial sites and Δt was the pulse transit time. Higher values represent increased stiffness, and values >10 m/s are associated with increased risk for cardiovascular events. Results: Twenty-five participants were assessed: 11 participants 4.7±2.4 years post-stroke and 14 older adults without stroke. The non-stroke group was older (73.1±3.9 vs. 65.2±9.4 years, P=0.009), while the stroke group had lower MoCA scores (21.2±3.2 vs. 24.4±2.8, P=0.01). There were no between-group differences in cfPWV (stroke 9.4 m/s vs. older adults 9.9 m/s, P=0.49), when controlling for age and MoCA scores. In backward regression analysis, age explained 21% of the variance of cfPWV (P=0.03), while MoCA was not a contributor. Conclusions: In conclusion, these results suggest that age is a significant correlate of arterial stiffness, regardless of the presence of stroke or cognitive impairment. Ongoing work will examine whether stroke history also contributes to arterial stiffness when groups are matched for age.

In this paper, the ram of boring and milling machining center is taken as the research object. A new method that hydraulic pull rods compensation is proposed to solve the problem of deformation compensation of long stroke ram of boring and milling machining center. Firstly, the method of finite element analysis is used to get the laws of ram deformation and the relationship curve between the ram deformation and the stroke of ram. Secondly, the preliminary calculation value of pull rods compensation force is derived based on the theoretical analysis of material mechanics. The relationship curve between compensation force and the stroke of ram is obtained by finite element analysis and polynomial least squares method. Finally, the analyzed results are as follows: the laws of ram deformation distribution is accurately predicted by the used method, the deflection error of the ram is well controlled,and the machining precision is significantly improved.

Purpose – This paper aims to analyse the influence of environmental proactivity on cost and differentiation competitive advantages, and to explore the double relationship between environmental proactivity and business performance. Design/methodology/approach – The population consists of all three- to five-star hotels in Spain. A sample of 350 hotels was classified according to environmental proactivity and performance levels, employing a two-step cluster analysis. Significant differences between groups were examined. Findings – The results show two types of environmental behaviour (reactive and proactive), with proactive hotels developing significantly better on both cost and differentiation competitive advantage and achieving significantly higher performance levels. Hotels which achieve above average business performance levels are significantly more environmentally proactive. Research limitations/implications – The present paper demonstrates that environmental management is related to competitive advantages and business performance. Environmental management systems are more developed in higher category, chain-affiliated and larger hotels. This could be due to having more resources to develop their environmental capability. The environmental proactivity scale employed in this study is presented as a reference measure for hotel managers to benchmark their current practices and implement environmental improvements. Originality/value – First, measuring environmental proactivity using four managerial systems (operative, information, strategic and technical) is innovative and provides a more detailed approach to measuring environmental proactivity. Second, demonstrating a double association between environmental proactivity and performance provides fresh insights into the relationship between these variables.
