Abstract
In this work we will discuss the suitability of carbon isotope analysis in plants for the assessment of environmental changes and their effects on crops and natural systems. For C3 species, carbon isotope composition (δ13C) of plant tissues constitutes an integrated record of the miscellaneous climatic and physiological factors that affect carbon assimilation and/or stomatal conductance. Here we present a literature review on the relationship between different environmental parameters and δ13C in both herbaceous plants and trees, including some examples and case studies. We will also consider the applicability of some of these relationships in palaeoecological studies, as well as for the assessment of climate change dynamics and its implications. Major advantages and limitations of this technique are further discussed.

Abstract
Purpose
In this paper, the authors investigated a proposed radio-frequency identification (RFID)-based meat supply chain to monitor quality and safety of meat products we purchase from supermarkets. The supply chain consists of farms, abattoirs and retailers. The purpose of this paper is to determine a cost-effective trade-off decision obtained from a developed multi-criteria optimization model based on three objectives. These objectives include customer satisfaction in percentage of product quantity as requested by customers, product quality in numbers of meat products and the total implementation cost. Furthermore, this work was aimed at determining the number and locations of farms and abattoirs that should be established and quantities of products that need to be transported between entities of the proposed supply chain.
Design/methodology/approach
To this aim, a tri-criteria optimization model was developed. The considered criteria were used for minimizing the total implementation cost and maximizing customer satisfaction and product quality. In order to obtain Pareto solutions based on the developed model, four solution approaches were employed. Subsequently, a new decision-making algorithm was developed to select the superior solution approach in terms of values of the three criteria.
Findings
A case study was applied to examine the applicability of the developed model and the performance of the proposed solution approaches. The computational results proved the applicability of the developed model in obtaining a trade-off among the considered criteria and solving the RFID-based meat supply chain design problem.
Practical implications
The developed tri-criteria optimization model can be used by decision makers as an aid to design and optimize food supply chains.
Originality/value
This paper presents a development of first, a cost-effective optimization approach for a proposed RFID-based meat supply chain seeking a trade-off among three conflicting criteria; and second, a new decision-making algorithm which can be used for any multi-criteria problem to select the best Pareto solution.

Abstract
Purpose
The purpose of this paper is to explore the economy of Persian Gulf countries following a post‐oil economy. This is accompanied with a futurology study and planning of certain scenarios that can be applied to these countries.
Design/methodology/approach
This study applies a futurology approach by investigating various scenarios to explore the Arab economy after oil. As such, a series of possible policies are proposed that can be undertaken by Arab countries depending on their public policy. Each of the suggested policies involves different scenarios that have been formed and analyzed using an era‐based cellular planning system.
Findings
The findings propose three main policies to be undertaken by Arab countries including: investing the oil income in miscellaneous economic baskets in order to minimize the vulnerability and maximize the profits; reducing the oil production in the coming years and transforming the one‐product oil economy to a value added petrochemical economy; and seeking new sources of income and wealth. In addition, findings emphasize the necessity for using renewable and lasting wealth resources and minimizing the dependency of countries on the oil economy.
Originality/value
The proposed scenarios in the study can act as strategic constructs in strengthening the scenario sets in the consecutive years and help develop other scenarios in the future. As such, this paper would be of interest to governmental advisors, strategic planners and policy‐makers involved in studies related to the Middle East.
