Regional non-hazardous landfill site selection by integrating fuzzy logic, AHP and geographic information systems

Abstract: This study presents a geographic information systems-based multi-criteria site selection of non-hazardous regional landfill in Polog Region, Macedonia. The multi-criteria decision framework integrates legal requirements and physical constraints that relate to environmental and economic concerns and builds a hierarchy model for landfill suitability. The methodology is used for preliminary assessment of the most suitable landfill sites by combining fuzzy set theory and analytic hierarchy process (AHP). The fuzzy set theory is used to standardize criteria using different fuzzy membership functions while the AHP is used to establish the relative importance of the criteria. The AHP makes pairwise comparisons of relative importance between hierarchy elements grouped by environmental and economic decision criteria. The landfill suitability is achieved by applying weighted linear combination that uses a comparison matrix to aggregate different importance scenarios associated with environmental and economic objectives. The results from the study suggested that a least suitable landfill area of 1.0% from the total is generated when environmental and economic objectives are valued equally while a most suitable landfill area of 1.8% area is generated when the economic objective is valued higher. Such results are aimed for enhancement of regional landfill site selection in the country that is compliant with modern EU standards.

Family-supportive supervisor behaviors, work engagement, and subjective well-being: a contextually dependent mediated process.

Abstract: Grounded in a multistudy framework, we examined the relationship between family-supportive supervisor behaviors, work engagement, and subjective well-being as a contextually dependent mediated process. In Study 1 (N = 310), based on broaden-and-build and conservation of resources theories, we tested the proposed mediated process while controlling for perceived organizational support and perceived managerial effectiveness. We also demonstrated that family-supportive supervisor behaviors are distinguishable from general supervisor behaviors. In Study 2 (N = 1,640), using multigroup structural equation modeling, we validated and extended Study 1 results by examining how the mediated model varied based on 2 contextualizing constructs: (a) dependent care responsibilities and (b) availability of family-friendly benefits. Although the mediational results were contextually dependent, they were not necessarily consistent with hypothesizing based on conservation of resources theory. Practical implications are emphasized in addition to future research directions.

In the eyes of the beholder: cognitive appraisals as mediators of the association between interparental conflict and youth maladjustment.

Abstract: Although the association between interparental conflict and youth maladjustment has been established, processes underlying this relationship are less understood. In this investigation, children's conflict appraisals were examined as mediating variables. In Study 1, 1,893 6th graders reported their perceptions of conflict and appraisals of threat and self-blame. Youth and teachers reported on externalizing and internalizing problems. In Study 2, 416 married parents from the larger sample reported their conflict and youth maladjustment. Children's appraisals of coping efficacy also were examined. Perceived threat, self-blame, and coping efficacy were salient mediators of overt conflict and triangulation, particularly for internalizing problems. Findings indicate that children's beliefs about interparental conflict play an important role in their adjustment to this family stressor.

Thermally activated delayed photoluminescence from pyrenyl-functionalized CdSe quantum dots.

Abstract: The generation and transfer of triplet excitons across semiconductor nanomaterial-molecular interfaces will play an important role in emerging photonic and optoelectronic technologies, and understanding the rules that govern such phenomena is essential. The ability to cooperatively merge the photophysical properties of semiconductor quantum dots with those of well-understood and inexpensive molecular chromophores is therefore paramount. Here we show that 1-pyrenecarboxylic acid-functionalized CdSe quantum dots undergo thermally activated delayed photoluminescence. This phenomenon results from a near quantitative triplet-triplet energy transfer from the nanocrystals to 1-pyrenecarboxylic acid, producing a molecular triplet-state 'reservoir' that thermally repopulates the photoluminescent state of CdSe through endothermic reverse triplet-triplet energy transfer. The photoluminescence properties are systematically and predictably tuned through variation of the quantum dot-molecule energy gap, temperature and the triplet-excited-state lifetime of the molecular adsorbate. The concepts developed are likely to be applicable to semiconductor nanocrystals interfaced with molecular chromophores, enabling potential applications of their combined excited states.
