Community engagement in the management of biosolids: lessons from four new zealand studies






Abstract: Biosolids management has been largely overlooked as an issue for environmental co-management, collaborative learning and public participation. This paper summarises four research projects on facilitating community involvement in biosolids management in New Zealand. The authors situate these studies both in relation to the New Zealand institutional and policy context for the management of biosolids and in relation to the themes of public participation and social learning in the literature on community involvement in environmental management. From the studies it can be concluded that: the incorporation of the knowledge and views of Māori is important from both public-participation and social-learning perspectives; both public-participation and social-learning approaches must consider the role of issue-definition in relation to willingness to participate; democratic accountability remains a challenge for both approaches; and locating biosolids management within an integrated water-and-wastewater or sustainable waste-management strategy may facilitate wider community participation as well as better-coordinated decision-making.

Communication as ethical facilitator

The purpose of the article is to offer a reflection on the ethical aspect of communication, more from a practised, experienced perspective than according to abstract models characterised by theoretical regulation and definition. Specifically, through references to the crisis of confidence that is currently sweeping Europe, it will attempt to show how communication can constitute a natural place for training and cooperative construction of new values and principles of ethical and moral regulation across the various fields of social activity, from the world of enterprise to that of institutions.

Common fixed point theorems for weakly compatible maps satisfying common (e.a.) property in intuitionistic fuzzy metric spaces using implicit relation

In this paper, employing the common (E.A.) property, we prove a common fixed theorem for weakly compatible mappings via an implicit relation in intuitionistic fuzzy metric space. [ABSTRACT FROM AUTHOR]

Combined ultrasound/ozone degradation of carbazole in apg1214 surfactant solution

Abstract: We examined the effects of power and treatment time on the ultrasonically enhanced ozonation of carbazole dissolved in APG1214 surfactant solutions, including an analysis of the mechanism of l formation, the zeta potential of the colloidal suspension, the influence of ultrasound on micellar morphology, and the degradation kinetics for carbazole and APG1214. A 30min ultrasound treatment at 28kHz and 20W improved the degradation of carbazole by 5–10%, while power levels of 40W and 80W provided improvements only during the first 5min and resulted in reduced degradation after 15min. The tration was inversely proportional to ultrasound power, and directly proportional to the irradiation time. The absolute value of the APG1214 micelle zeta potential was inversely proportional to power and decreased with increasing irradiation time. The relationships of l concentration in APG1214 micelles, the zeta potential, and the micellar dynamic radius (R h) to ultrasonic power and time are the key factors affecting carbazole degradation in this system.

Coincidences and common fixed point theorems for ϕ-contractive type single-valued and multivalued mappings

In this paper we prove some coincidences and fixed point theorems for a pair of single-valued and multivalued mappings satisfying ϕ-contractive condition. Our results improve and extend some well known previous results. [ABSTRACT FROM AUTHOR]

Chemokines and nk cells: regulators of development, trafficking and functions

Abstract: NK cells are innate lymphocytes capable of killing malignant or infected cells and to produce a wide array of cytokines and chemokines following activation. Chemokines, play critical roles in the regulation of NK cell tissue distribution in normal conditions as well as their rapid recruitment to the parenchyma of injured organs during inflammation, which is critical for NK cell ability to promote protective responses. In this regard, differences in chemokine receptor expression have been reported on specialized NK cell subsets with distinct effector functions and tissue distribution. Besides their role in the regulation of NK cell trafficking, chemotactic molecules can also affect NK cell effector functions by regulating their priming and their ability to kill and secrete cytokines.

Chemokines and adult bone marrow stem cells

Abstract: The adult bone contains a number of distinct populations of stem cells, including haematopoietic stem cells, mesenchymal stem cells, endothelial progenitor cells and fibrocytes. While haematopoietic stem cells are required to provide a lifelong supply of blood cells it is thought that the other populations of stem cells play a role in tissue regeneration and potentially disease. The chemokine CXCL12 is produced constitutively in the bone marrow and, acting via CXCR4, is critical in maintaining HSPCs in a quiescent state and retaining all subsets of stem and progenitor cells in the bone marrow environment. The cytokine G-CSF, used clinically to mobilize haematopoietic stem cells for bone marrow transplants, activates the sympathetic nervous system and bone marrow macrophages to reduce the expression of CXCL12 by bone marrow stromal cells, thereby promoting the exit of haematopoietic stem cells from the bone marrow. Understanding the molecular mechanisms underlying G-CSF stimulated mobilization has led to development of CXCR4 antagonists as fast acting mobilizing agents for haematopoietic stem cells. Evidence now suggests that CXCR4 antagonists can similarly mobilize distinct subsets of progenitor cells, namely the endothelial progenitor cells and mesenchymal stem cells, but this requires conditioning of the bone marrow with VEGF rather than G-CSF.

Characteristics of interlaminar stresses for damages in adhesively-bonded composite single lap joints

In this paper three-dimensional non-linear finite element analyses are carried out to evaluate accurately the stresses over the different critical surfaces for adhesion failure, cohesion failure and delamination damages of an adhesively-bonded fibre-reinforced polymer (FRP) composite single lap joint (SLJ) subjected to an in-plane loading. The top and bottom adherends of the SLJ are formed by eight layers of unidirectional graphite FRP composite and the material of the adhesive is epoxy. The out-of-plane stresses and their distribution over the critical surfaces are presented, and conclusions about the damages and failures for the adhesively-bonded composite SLJ are drawn.

Changes while implementing law-reforms and albania as a new eu candidate country

Obviously the study of this paper consists on identifying and why not in addressing the important factors underlying the bailiff office in Albania and changes in the form of organization, under the administrative and implementing reforms in law. The paper also introduces some changes in national law, private or state organizational form. The Bailiff Section in Albania serves two key roles as part of the Judiciary. Both roles help to ensure that justice is fairly administered and carry to its proper conclusion. The Bailiffs and their assistants serve summonses and other important legal documents on parties as required by a Court or Tribunal, or as requested by a person who is a party to litigation, as an instance, a court or tribunal sentence which parties are required to attend. Surely it cannot proceed unless there is proof that the parties concerned have had the summonses attending properly served on them in a specified way by law. The judicial power is one of the most important issues on the legal state. As stated in the Albanian constitution, one basic principle is: equality and control between governments. Our paper research will analyze the justice reforms in Albania; will analyze bailiff organizational management (private or state form). [ABSTRACT FROM AUTHOR]

Boolean centre of pre a*-algebra

This manuscript illustrates the essential congruence θx on a Pre A*-algebra A and arrive at a variety of properties of these. Also it bear out certain properties of the operations Γx(p, q) and Φx. It has been confirmed that θ is a factor congruence on A if and only if θ = θX for some xeB(A). Further it was proved that the centre B (A) of a Pre A*-algebra A with 1 is isomorphic with the Boolean centre B(A) of A. [ABSTRACT FROM AUTHOR]
