Abstract
Electrokinetics (EK) is an emerging remediation technology for the in situ removal of heavy metals, volatile organic compounds, and radionuclides from soils and sediments. Naval Air Weapons Station Point Mugu, California will host an EK technology demonstration. The demonstration will consist of installing and operating an EK system, which is engineered to remove cadmium and chromium from former electroplating waste lagoons. The selected site is adjacent to and encroaches on an environmentally sensitive salt marsh are for a federally protected wildlife. The electrokinetic process will be used to mobilize and extract heavy metals from the metals‐contaminated soil by applying a low amperage direct current across an array of electrodes placed in the contaminated soil. The demonstration will focus on the effectiveness of the EK process for removing heavy metals from the tidal marsh area. The EK demonstration will be used to collect cost‐effective data necessary to address both the technical and economic feasibility of using this technology in areas where soils are porous, water is brackish, and the system is susceptible to tidal influences.

Abstract
Purpose
Neuroeconomics and neurofinance are emerging as intriguing fields of research, despite sharing ambiguity with the concepts of neuroscience. The relationship among the concepts of economics, finance and neuroscience is not explicitly defined in the past literature, which distorts the use of neuroeconomics and neurofinance approaches in real-world practice for financial decision-making. The purpose of this paper is to consolidate the literature in the field of neuroeconomics and neurofinance to set up the research agenda for the upcoming scholarship in the field.
Design/methodology/approach
The purpose of this paper is to consolidates the extant literature in the fields of neuroeconomics and neurofinance by conducting an extensive systematic literature review to investigate the current state and define the relationship between economics, finance and neuroscience.
Findings
This paper identifies and explains the explicit relationship between different sub-fields of neuroscience with neuroeconomics and neurofinance and providing instances for future research studies.
Originality/value
The exclusive and extensive literature survey in the form of systematic literature review is undertaken for understanding the fields of neuroeconomics and neurofinance and is the key highlight of this paper. Another, interesting fact lies with matching the literature in neuroeconomics and neurofinance with further sub-fields of neuroscience such as neurophysiology, neuroanatomy, molecular neuroscience and cognitive neuroscience.

Abstract
Purpose
Probiotics are known to extend health benefits and therefore may be included during yoghurt manufacture to enhance its prophylactic properties. Different probiotic strains may exhibit diverse biotechnological behaviour in association with yoghurt cultures, therefore interactive behaviour amongst probiotic and yoghurt cultures must be evaluated prior to their commercial application. This paper aims to assess the effect of inclusion of different probiotic cultures on various biotechnological (technological, dietetic and prophylactic) characteristics of yoghurt cultures.
Design/methodology/approach
Yoghurt was assessed for technological characteristics based on acidification and flavour production, dietetic characteristics based on proteolytic activity, vitamin synthesis and L (+) lactic acid production and prophylactic characteristics based on β‐galactosidase activity, antibacterial spectrum, viability in product as well as during gastro‐intestinal transit, intestinal colonization, immunomodulation, anti‐carcinogenicity and hypocholesterolemic effect.
Findings
Different probiotic cultures exhibited diverse technological, dietetic and prophylactic behaviour in association with yoghurt cultures. Functional properties of traditional yoghurt could be enhanced with the combined introduction of probiotic cultures such as Bifidobacterium bifidum, Bifidobacterium infantis and Lactobacillus acidophilus and the resultant product may be recommended for consumption as a dietary adjunct.
Originality/value
The paper shows that combined introduction of probiotic cultures such as B. bifidum, B. infantis and L. acidophilus, as microbial additives during the manufacture of yoghurt would result in a product with enhanced functional properties.

Abstract
Purpose
Tuber crops are extremely important for humans, being extensively used in many cultures and mainly in poor and developing countries. Tanias (Xanthosoma Schott) belong to the Aracea family and have been commonly used as a staple food since pre‐Columbian times. Nowadays, tanias are integrated in the staple diet of several countries in the Americas, West Africa, Asia and the Pacific. In order to shed light on their potential and possible risks for human nutrition, nutritional and anti‐nutritional evaluations of different compounds synthesized by tania corms were carried out by using seven tropical species.
Design/methodology/approach
Classical analyses for non‐structural carbohydrates and nitrogenated compounds as well inhibitory assays towards α‐amylases and proteases were employed.
Findings
Tests for quantitation of reducing sugars, soluble polysaccharides, free amino acid content and total protein amounts presented variable scores among studied species. Nevertheless, the amounts of non‐starchy polysaccharides and sugars were less than those observed in other tuber crops, such as potato, cassava, sweet potato and yam. Otherwise, when anti‐nutritional compounds were evaluated, no digestive enzyme inhibitory activity was detected in performed assays. Moreover, Xanthosoma atrovirens, Xanthosoma brasiliense and Xanthosoma mafaffa showed agglutination activity towards blood type B, probably due to the presence of lectins.
Research limitations/implications
In summary, data here presented suggest that it is not possible to indicate a single tania candidate as the best choice for human consumption.
Originality/value
The paper presents a pioneer comparison of nutritional and antinutritional compounds between different species of tania corms.

Abstract
Purpose
The purpose of this paper is to investigate meat traceability by outlining the different perspectives and opinions of meat supply chain stakeholders (SCSs); it also evaluates potential of acceptance of blockchain technology (BCT) as a viable transparency and traceability system (TTS).
Design/methodology/approach
A questionnaire survey of 141 consumers reveals their opinions about TTSs. In addition, semi-structured interviews with seven retail managers, four government officials and one blockchain service provider (Project Provenance Ltd) provide expert insights.
Findings
The results demonstrate that consumers are overwhelmed by the amount and complexity of certification labels. As a TTS, BCT implementation appears to have significant positive influences on consumers’ purchasing decisions, mediated by consumers’ quality perceptions. This study reveals the discordant perspectives of different stakeholders with regard to the importance of a BCT-based TTS.
Originality/value
This study investigates current TTSs and certification labels, and probes customer perception of a potential BCT-based solution for meat traceability. Changes to supply chains’ mentality and the active establishment of trust in BCT applications are needed. Firms should take both holistic and altruistic views to deal with the challenges of TTSs in the meat supply chain. The adoption of BCT, in combination with DNA coding, seems promising as a solution to many of the issues that currently plague TTSs.

Abstract
Purpose – This chapter contributes to comparative biopolitics and reviews primatological literature, especially about our nearest relatives, the Great Apes.
Design/methodology/approach – Biopolitics in this chapter means evolutionarily informed political science, with emphasis on power relations. I review the literature on intrasexual and intersexual dominance interactions among individuals and competitive and/or agonistic interactions among groups in the Great Apes (Hominidae, formerly Pongidae): orangutan (Pongo with two species and three subspecies), gorilla (Gorilla with four subspecies), bonobo (Pan paniscus), and common chimpanzee (Pan troglodytes with four subspecies). In the final section I present some (speculative) thoughts on Pan prior or the modern human ancestor.
Findings – Not only Man is a political animal.
Originality/value – Impartial, objective, and as complete as possible review of the literature for the students of (comparative) politics, ethology, and psychology.

Abstract
We wonder if, in the history of the world, any conference devoted to the intellectual interests of mankind has ever been held in such circumstances as made memorable the Fortieth Annual Meeting of the Library Association. For the whole week before those in and near London had been submitted to an ordeal well calculated to try the strongest nerves; an ordeal borne, it is true, with remarkable stoicism, but, nevertheless, one not likely to induce that calm, judicial frame of mind in which library topics should be discussed. Fortunately, however, the night before the opening meeting was the last of that particular series of air attacks, and the whole meeting passed in peace, so far as London was concerned. Raids and rumours of them may have reduced the attendance somewhat; it is fair to suppose that they did; yet the attendance, when all things are considered, was creditable to the Association.

Abstract
I suppose that most noticeable of all the changes in our profession since I came into it has been the multiplicity of the methods by which one can become a librarian. A. E. Standley says in a recent article in the L.A.R., in 1970: “The term librarian includes the Library Association chartered librarian, the graduate with a degree in librarianship, the scholar librarian, the information and intelligence officer, the translator, the abstracter, the non‐library‐qualified subject expert”.

Abstract
Purpose
The purpose of this paper is to propose a conceptual framework that highlights the reinforcing nature of global consumer culture (GCC). In doing so, this paper highlights a dialectic process in which consumers trade-off, appropriate, indigenize and creolize consumption into multiple GCCs.
Design/methodology/approach
The approach is conceptual with illustrative examples.
Findings
GCC is a reinforcing process shaped by global culture flows, acculturation, deterritorialization, and cultural and geographic specific entities. This process allows consumers to indigenize GCC, and GCC to contemporaneously appropriate aspects from myriad localized cultures, producing creolized cultures.
Research limitations/implications
Marketing research and practices need to shift away from the dichotomous view of global and local consumption fueled by a misleading view of segmentation. Instead, marketers should focus on identifying the permutations of emerging GCCs, how these operate according to the context and accordingly position their marketing mix to accommodate them.
Originality/value
The proposed model reviews and integrates existing literature to highlight fundamental research directions that present a comprehensive overview of GCCs, its shortcomings and future directions.

Abstract
The institution of food and cookery exhibitions and the dissemination of practical knowledge with respect to cookery by means of lectures and demonstrations are excellent things in their way. But while it is important that better and more scientific attention should be generally given to the preparation of food for the table, it must be admitted to be at least equally important to insure that the food before it comes into the hands of the expert cook shall be free from adulteration, and as far as possible from impurity,—that it should be, in fact, of the quality expected. Protection up to a certain point and in certain directions is afforded to the consumer by penal enactments, and hitherto the general public have been disposed to believe that those enactments are in their nature and in their application such as to guarantee a fairly general supply of articles of tolerable quality. The adulteration laws, however, while absolutely necessary for the purpose of holding many forms of fraud in check, and particularly for keeping them within certain bounds, cannot afford any guarantees of superior, or even of good, quality. Except in rare instances, even those who control the supply of articles of food to large public and private establishments fail to take steps to assure themselves that the nature and quality of the goods supplied to them are what they are represented to be. The sophisticator and adulterator are always with us. The temptations to undersell and to misrepresent seem to be so strong that firms and individuals from whom far better things might reasonably be expected fall away from the right path with deplorable facility, and seek to save themselves, should they by chance be brought to book, by forms of quibbling and wriggling which are in themselves sufficient to show the moral rottenness which can be brought about by an insatiable lust for gain. There is, unfortunately, cheating to be met with at every turn, and it behoves at least those who control the purchase and the cooking of food on the large scale to do what they can to insure the supply to them of articles which have not been tampered with, and which are in all respects of proper quality, both by insisting on being furnished with sufficiently authoritative guarantees by the vendors, and by themselves causing the application of reasonably frequent scientific checks upon the quality of the goods.
