Interest-free financing in agro-industry is an exciting topic that has been developed by many researchers, but there is no clarity regarding the road map for future research. Therefore, formulations such as concepts, theories, methods, and research gaps, focusing on interest-free financing in agro-industry, are essential. This literature study was conducted using a systematic literature review method. The data used are secondary data from textbooks, theses/dissertations, conference papers, journals, scientific articles, and working papers. This study resulted in the formulation of the theory, concepts, and methods studied in the form of an explanation of 8 sub-topics of research gaps supported by references and explanations of state of the art. They are making it easier for researchers who have the same interest in developing and looking for novelties with the topic of interest-free financing research in the agro-industry.

Bibliometric Review

Recently, architecture engineering and construction (AEC) industry benefits from building information modeling (BIM) as a technology-based development, to enhance collaboration and increase the efficiency of construction projects. After implementing BIM in design and construction phases, developed countries now head towards utilization of BIM in facilities management (FM) processes. As ranking among the leading AEC industries, Turkey not only follows latest developments but also promises valuable potentials for both theoretical and practical improvement of BIM. Based on the studies published in BIM field, this study applies bibliometric review approach to analyze the state-of-the-art situation of the field in Turkey, and determine potential research areas, especially in BIM and FM intersection. Following the systematic literature search that aims to introduce current efforts of Turkish researchers in BIM field, the qualitative analysis categorizes these efforts according to life cycle phases of a construction project and provides a vision on existing knowledge as well as research gaps. Findings of this study point out the important contributions of Turkey to BIM field especially in design and/or construction phases. A prominent conclusion of this study also signals a need for more FM oriented approach in BIM researches.

In this era of technology, people rely on online posted reviews before buying any product. These reviews are very important for both the consumers and people. Consumers and people use this information for decision making while buying products or investing money in any product. This has inclined the spammers to generate spam or fake reviews so that they can recommend their products and beat the competitors. Spammers have developed many systems to generate the bulk of spam reviews within hours. Many techniques, strategies have been designed and recommended to resolve the issue of spam reviews. In this paper, a complete review of existing techniques and strategies for detecting spam review is discussed. Apart from reviewing the state-of-the-art research studies on spam review detection, a taxonomy on techniques of machine learning for spam review detection has been proposed. Moreover, its focus on research gaps and future recommendations for spam review identification.

Whole Life Cycle

Pallets are among the most used returnable transport items (RTIs), and they are critical assets for a supply chain as they have significant environmental and economic impacts during their whole life cycle. Differently from other packaging products, pallets are specifically designed to be repeatably repaired and reinjected for use. While this environmentally is beneficial as it reduces waste, it can create complex interactions between the stakeholder-involved manufacturers, pallet providers, users and recyclers. Further, the number of different actors is usually high, and the flow of materials among them needs to be coordinated. In addition, different business models can be implemented (such as internal management versus outsourcing) as well as logistics alternatives (closed- versus open-loop). Thus, the aims of this study are first to propose a systematization of design and management decisions regarding the pallet supply chain; next, to review the state of the art models and tools adopted to support each decision process relying on an analysis of the archival literature published between 1978 and 2021 on pallet management, to summarize the main decision problems addressed by the different stakeholders involved in the pallet life cycle and the adopted methods, and, finally, to highlight potential existing research gaps. This effort helps to outline potential contributions towards more sustainable pallet supply chains and can support pallet operators and companies in evaluating solutions to increase the economic and environmental sustainability of their pallet management. Results show that the perspectives of the pallet provider and of the supply chain are the most widely addressed in the existing literature, while those of pallet manufacturers and repairers should be further analyzed.

Abstract In recent years, local food systems have come to be seen as a new possibility in creating markets for family farming. These systems are based on local production and consumption structures, with a primary focus on sustainability, locality and proximity. It is essential to understand the dynamics of these systems and their impact in the context of family farmers. Thus, this article seeks to identify in the literature the main theories and concepts used in the analysis of “local food systems”, verifying the state of the art of its theoretical elements related to the concept of “family farming” in Brazilian and international academia. The methodological procedure employed was a systematic literature review following the Methodi Ordinatio protocol, covering 30 articles indexed in the search portal Periódicos - Capes and in the database ProQuest. The main approaches included in this theme are presented in a summarized form, as well as the research gaps in the area are identified. The results show that these concepts involve themes such as local rural development, politicization of consumption, sustainability, market niches, agroecology, territorial valorization, and institutional programs.

The detection of manipulated videos represents a highly relevant problem in multimedia forensics, which has been widely investigated in the last years. However, a common trait of published studies is the fact that the forensic analysis is typically applied on data prior to their potential dissemination over the web. This work addresses the challenging scenario where manipulated videos are first shared through social media platforms and then are subject to the forensic analysis. In this context, a large scale performance evaluation has been carried out involving general purpose deep networks and state-of-the-art manipulated data, and studying different effects. Results confirm that a performance drop is observed in every case when unseen shared data are tested by networks trained on non-shared data; however, fine-tuning operations can mitigate this problem. Also, we show that the output of differently trained networks can carry useful forensic information for the identification of the specific technique used for visual manipulation, both for shared and non-shared data.

Automated Fiber Placement

The automated fiber placement process (AFP) enables the manufacturing of large and geometrical complex fiber composite structures with high quality at low cycle times. Although the AFP process is highly accurate and reproducible, manufacturing induced imperfections in the produced composite structure occur. This review summarizes and classifies typical AFP-related manufacturing defects. Several methodologies for evaluating the effects of such manufacturing defects from the literature are reviewed. This review paper presents recent scientific contributions and discusses proposed experimental and simulation-based methodologies. Among the identified ten defect classes, gaps and overlaps are predominant. This paper focuses then on methods for modelling and assessing gaps and overlaps. The state of the art in modelling gaps and overlaps and assessing their influence on mechanical properties is presented. Finally, research gaps and remaining issues are identified.

Response Capability

The arms race between cyber attackers and defenders has evolved to the point where an effective counter-measure strategy requires the use of an automated, distributed, and coordinated response. A key difficulty in achieving this goal lies in providing reliable measures by which to select appropriate responses to a wide variety of potential intrusions in a diverse population of network environments. In this chapter, the authors provide an analysis of the current state of automated intrusion response metrics from a pragmatic perspective. This analysis includes a review of the current state of the art as well as descriptions of the steps required to implement current work in production environments. The authors also discuss the research gaps that must be filled to improve security professionals’ ability to implement an automated intrusion response capability.
