A Fuzzy Multi-Criteria Model for Municipal Waste Treatment Systems Evaluation including Energy Recovery

One of the recent problems on waste sorting systems is their performance evaluation for proper decision making and management. For this purpose, multi-criteria methods can be used to evaluate the sorting system from both operational and financial perspectives. According to a recent literature review, there are no solutions for evaluating waste sorting systems that take into account: sorting point utilisation, sorting efficiency, waste stream irregularity, and technical system availability. In addition, the problem of data uncertainty and the need to use expert judgements indicate the need for the implementation of methods adjusted to the qualitative and quantitative assessment, such as the fuzzy approach. Following this, in order to overcome the presented limitations, the authors introduced the new assessment method for waste sorting systems based on multi-criteria model implementation and fuzzy theory use. Therefore, the developed model was based on a hierarchical fuzzy logic model for which appropriate membership function parameters and inference rules were defined. The specificity of the chosen assessment criteria and their justification was provided. The model has been implemented to evaluate one of the waste sorting plants in Wroclaw, Poland. Tests have been conducted for seven different configurations of waste sorting lines (with variable input parameters). The study focuses on analysing the amount of selected waste at each station in relation to the total stream size of each fraction. Efficiency was measured by the mass of the collected waste and the number of pieces of waste in each fraction. Based on the obtained results, estimations of particular parameters of the model were made, and the results were presented and commented on. It was shown that there is a significant relationship between the level of system evaluation and sorting efficiency and an inverse relationship with the level of RDF obtained. The analysis was based on Pearson’s linear correlation coefficient estimation and linear regression implementation.

Determinants of de jure adoption of international financial reporting standards: a review

Purpose The purpose of this paper is to systematically review extant studies on what makes a country fully, partially or not adopt international financial reporting standards (IFRS) and categorize these factors into meaningful categories. In so doing, this study facilitates policy-making for accounting and economic standard setters and also points out conflicting viewpoints in the current literature, thus, opportunities for future research. Design/methodology/approach This paper is a literature review on academic studies that examine factors influencing national adoption of IFRS. The reviewed articles are limited to published, peer-reviewed papers only. Findings Overall, the review suggests that although a wide range of determinants on national adoption of IFRS has been identified, prior literature consists of conflicting viewpoints on what influence national accounting policies toward IFRS, thus, highlighting areas in which there are needs for future research. Research limitations/implications First, this study focuses only on the de jure adoption of IFRS. Second, the study focuses mainly on research findings, not theory use in the extant literature. Originality/value To the best of the author’s knowledge, this is the first study, which provides a comprehensive review of studies on de jure IFRS adoption.

Non-synchronism in theoretical research of information science

PurposeThis paper aims to reveal the global non-synchronism that exists in the theoretical research of information science (IS) by analyzing and comparing the distribution of theory use, creation and borrowing in four representative journals from the USA, the UK and China.Design/methodology/approachQuantitative content analysis is adopted as the research method. First, an analytical framework for non-synchronism in theoretical research of IS is constructed. Second, theories mentioned in the full texts of the research papers of four journals are extracted according to a theory dictionary made before. Third, the non-synchronism in the theoretical research of IS is analyzed.FindingsNon-synchronism exists in many aspects of the theoretical research of IS between journals, subject areas and countries/regions. The theoretical underdevelopment still exists in some subject areas of IS. IS presents obvious interdisciplinary characteristics. The theoretical distance from IS to social sciences is shorter than that to natural sciences.Research limitations/implicationsThis study investigates the theoretical research of IS from the perspective of non-synchronism theory, reveals the theoretical distance from IS to other sciences, deepens the communication between different subject and regional sub-communities of IS and provides new evidences for the necessity of developing domestic theories and theorists of IS.Originality/valueThis study introduces the theory of non-synchronism to IS research for the first time, investigates the new advances in theoretical research of IS and provides new quantitative evidences for the understanding of the interdisciplinary characteristics of IS and the necessity of better communication between sub-communities of IS.

The Impact of Theory in HPV Vaccination Promotion Research: A Systematic Review and Meta-Analysis

Objective: Numerous studies examined HPV vaccination promotional strategies. However, an overview of theory use, a synthesis of strategies’ effectiveness and an examination of the moderating influence of theory are absent. Data Source: We retrieved studies from Academic Search Complete, Business Source Complete, PubMed, PsycINFO, Web of Science, CMMC, CINAHL, and MEDLINE. Study Inclusion and Exclusion Criteria: 1) peer-reviewed articles written in English, 2) experimental or quasi-experimental, 3) measure HPV vaccination-related outcomes, 4) had to contain a control condition and report statistics necessary for conversion (for meta-analysis only). Data Extraction: 70 and 30 studies were included for the systematic review and meta-analysis respectively. Data Synthesis: Four major categories were coded: study information, theory use, type of theory, and outcomes. Two independent coders coded the sample (Cohen’s Kappa ranged from .8 to 1). Results: Most of the studies were based in the U.S. (77%, k = 54) with convenient samples (80%, k = 56), targeted toward females (46%, k = 32), and around a quarter did not employ any theories (47%, k = 33). Among theory-driven studies, the most commonly used were Framing (22%, k = 19), Health Belief Model (HBM; 13%, k = 12), and Narrative (7%, k = 6). Among controlled studies, promotional strategies were significantly more effective compared to the control (r+ = .25, p < .001). Strategies guided by the information, motivation, behavioral skills model (IMB) were more effective (r+ = .75, p < .001) than studies guided by framing theory (r+ = −.23, p < .001), HBM (r+ = .01, p < .001), and other theories (r+ = .11, p < .001). Conclusion: This review contributes to HPV vaccination promotion literature by offering a comprehensive overview of promotional strategies and practical suggestions for future research and practices.

Theoretical Underpinnings in Research Investigating Barriers for Implementing Environmentally Sustainable Farming Practices: Insights from a Systematic Literature Review

Research has a critical role in supporting the implementation of farming practices that are appropriate for meeting food and climate security for a growing global population. Notwithstanding progress towards more sustainable agricultural production, the rate of change varies across and within regions and is, overall, too slow. Understanding what is and is not working at the implementation level and, critically, providing justified explanations on outcomes, is an important contribution of the literature. Based on the assumption that theory-informed research can contribute to adoption policy and practice, this review ascertained and described the use of theory in the identification and examination of barriers to adoption in studies included in a recent systematic literature review. Following the application of criteria for ‘theory use’, 16 studies out of 75 were found to have applied or built upon one or more of 14 theories and models in their research approaches, including established theories in the social and behavioural sciences, as well as systems based models developed specifically in the sustainable agriculture space. Following a description of theory and model use in the studies, results are discussed relative to how theoretical constructs and mechanisms within individual and across studies can assist in explaining why and how adoption of sustainable practices is constrained.
