Performance of an outdoor membrane photobioreactor for resource recovery from anaerobically treated sewage
2018
[EN] The objective of this work was to evaluate the performance of a pilot scale membrane photobioreactor (MPBR) for treating the effluent of an anaerobic membrane bioreactor (AnMBR) system. In particular, new experimental data on microalgae productivity, nutrient recovery, CO2 biofixation and energy recovery potential was obtained under different operating conditions, which would facilitate moving towards cost-effective microalgae cultivation on wastewater. To this aim, a 2.2-m(3) MPBR equipped with two commercial-scale hollow-fibre ultrafiltration membrane modules was operated treating the nutrient-loaded effluent from an AnMBR for sewage treatment. The influence of several design, enviro…
IS Security Policy Violations
2012
Employee violations of IS security policies are reported as a key concern for organizations. Although behavioral research on IS security has received increasing attention from IS scholars, little empirical research has examined this problem. To address this research gap, the authors test a model based on Rational Choice Theory RCT-a prominent criminological theory not yet applied in IS-which explains, in terms of a utilitarian calculation, an individual's decision to commit a violation. Empirical results show that the effects of informal sanctions, moral beliefs, and perceived benefits convincingly explain employee IS security policy violations, while the effect of formal sanctions is insig…
A Practical Approach to EA Planning and Development: the EA Management Grid
2004
Enterprise Architecture is gaining interest as a managerial tool for managing corporate ICT assets and their interplay. Our prior studies indicate that an ICT provider’s viewpoint on EA consulting, planning and development seems to be lacking in the proposed methodologies. Considering both literature and practical EA cases, we suggest an approach that supports restricted assignments in EA management. We present an EA Grid for the management of EA descriptions, requirements, constraints, as well as project tasks and deliverables, task preliminaries and dependencies in EA consulting and development. peerReviewed
Competitiveness and sustainability in horticulture: strategy for small businesses
2018
Vegetable cultivation has a significant history in the countries of the Mediterranean basin. Italy is an important horticultural producer and, in this context, Sicily offers ideal conditions for the protected cultivation of field vegetables. Apart from a few well-organised producers, in many areas horticulture is characterised by backward entrepreneurial systems and fragmented production lines that make the vegetable market one that is very close to being a rigged competition in which companies must accept the price and have no negotiating power. This situation has been aggravated even further by the recent economic crisis and the subsequent recession, resulting in the disappearance of the …
Effects of Perceived Identity Based on Corporate Social Responsibility: The Role of Consumer Identification with the Company
2009
The paper focuses on the mediating role of consumer identification with a company in the effect of corporate social responsibility (CSR)-based perceived identity on consumer behaviour. More specifically, it deals with the direct and indirect influences of identification with a socially responsible company on purchase intent, through two affective variables – attitude and affective commitment to the company. After the literature review that supports the hypotheses, an empirical study was carried out to test the proposed model. Findings show that CSR-based consumer-company identification influences purchase intent through the mediator role of company attitude and company commitment. This invo…
The outcomes of Ilizarov treatment in aseptic nonunions of the tibia stratified by treatment strategies and surgical techniques.
2020
Abstract INTRODUCTIONNonunions of the tibia, particularly those located in the distal third of the bone, are relatively common in clinical practice. There is no gold standard for the treatment of nonunions of the tibia. The purpose of our study was to assess the results of treatment with the Ilizarov method in patients with aseptic nonunions of the tibia, depending on the employed treatment strategies and surgical techniques.MATERIALS AND METHODSA total of 75patients with Ilizarov treatment of aseptic nonunions of the tibia were evaluated in the study. The patients’s mean age at the beginning of treatment was 46years.The mean follow-up period was 10years and 11months.The evaluated patients …
Image Segmentation by Deep Community Detection Approach
2017
International audience; To address the problem of segmenting an image into homogeneous communities this paper proposes an efficient algorithm to detect deep communities in the image by maximizing at each stage a new centrality measure, called the local Fiedler vector centrality (LFVC). This measure is associated with the sensitivity of algebraic connectivity to node removals. We show that a greedy node removal strategy, based on iterative maximization of LFVC, has bounded performance loss relative to the optimal, but intractable, combinatorial batch removal strategy. A remarkable feature of this method is the ability to segments the image automatically into homogeneous regions by maximizing…
Calculating the regional economic impact of the olympic games
2004
This study introduces a methodological concept to combine the cost‐benefit analysis and input‐output models to create a new method to regionalize Olympic costs and benefits in order to define the economic impact at the regional level. This new form of analysis is used to calculate the regional economic impact of the Frankfurt Rhein/Main region, which bid to stage the 2012 Olympics. A generalised view of the Frankfurt case study shows patterns that are valid for all impact studies of major sport events. Finally a sensitivity analysis is used to determine critical variables.
Different ways of measuring performance in the service industries: application in Spanish small and medium-sized hotels
2008
There is no suitable unit of analysis for explaining the profitability and competitiveness of the company, as typically pointed out in the debate between the disciplines of economics and management. After a study of the possible variables, we opted for those of minimum cost output and productivity, using these two measurements to analyse their application to Spanish hotels. The subsequent objective was to attempt to identify general strategies that could be applied to any SME within service industries. In situations where time and resources are not readily available to create action plans for each of the different types of SME, there is a need for incentives that can be applied to the creat…
Open strategizing on social media: A process model of emotional mechanisms and outcomes from un-orchestrated participation
2023
This study extends the discussion on open strategizing by following the development of unlimited participation in an ex-ante city merger case where participation was not orchestrated. The findings unravel how the aggregation of emotional expressions on social media results in an escalating conflict, and initiates attempts to mitigate grounded in decision-makers’ reflexiveness of social becoming(s). We theorize three emotional mechanisms – acceleration of emotional interaction, reinforcement of hostility as a discursive norm, and emotional empowerment – and outcomes originating from uncontrolled dynamics of inclusion and transparency. As such, we theorize open strategy as emerging organicall…
