Abstract

Purpose

In recent years, futures study methods, especially scenario analysis, are used to plan for disaster and emergency management. Scenario method is suitable for public level policy making. Scenarios generated alternative descriptive futures in all of the development field such as disaster studies. This paper aims to systematically review the articles that generated scenarios in disaster management to attain gaps, challenges and opportunities related to use of scenario analysis in disasters.

Design/methodology/approach

This is a systematic review that was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The keywords that searched included “disaster,” “emergency,” “crisis,” “disruptive event,” “futures study,” “foresight,” “scenario,” “community-based scenario planning,” “participatory scenario planning,” “scenario planning” and “scenario analysis.” The Google Scholar, ISI Web of Science, Science Direct, PubMed and Scopus databases were searched.

Findings

A total of 981 article gathered after initial search between electronic databases. At final step, only ten articles included in the study. The selected articles compared according to many aspects. Most of the scenarios that developed in disaster management and planning concentrated on climate change and flooding related hazards. Many of studies developed three or four scenarios that it seems the number is suitable for disaster planning.

Originality/value

The paper serves as an original guideline for disaster planning.

Abstract

Purpose

The purpose of this paper is to review existing research on retail supply chain responsiveness, develop categories to be included in a retail-specific responsiveness framework, and identify future research areas within the scope of retail supply chain responsiveness.

Design/methodology/approach

This paper presents an inductive systematic literature review of 46 academic, peer-reviewed articles. Based around the two major review questions on retailers’ role in the creation of supply chain responsiveness and future research areas, an inductive, qualitative, content analysis was conducted. Further analysis was conducted by using the software NVivo 11.

Findings

Existing research are grouped into a framework of four categories that together span the existing research. The categories are labelled supply chain orchestration, market orientation, supply chain operations and supply management. Two to three subthemes in each category are presented. Thereafter, promising future research areas are outlined, covering methodological issues, theoretical underpinnings, inclusion of context variables and outcomes of retail supply chain responsiveness.

Research limitations/implications

The conducted systematic literature review has been limited to academic, peer-reviewed articles.

Practical implications

The findings of the paper constitute a promising initial step towards a retail-specific framework on retail supply chain responsiveness.

Originality/value

The paper questions the comprehensiveness of established models in responsiveness, and argues that existing “general” literature on supply chain responsiveness gives little guidance and structure to retailers’ specific role and involvement in supply chain responsiveness. In particular, the paper focusses on the retailers’ role for creation of supply chain responsiveness, which has not previously been addressed in research.

Abstract

Purpose

In light of the recent dynamics, this paper aims to explore the last mile (LM) of e-commerce retailers. Two research questions are developed (1) What firm characteristics are critical in LM practices? and (2) How do LM practices differ based on the identified critical firm characteristics?

Design/methodology/approach

Data were collected via 10 interviews with e-commerce executives, as well as a survey on 200 e-commerce firms in different retail sectors in Sweden.

Findings

“Firm Size” and “Sales Channel-Mix” appear to be the top critical firm characteristics in LM practices. While last mile delivery (LMDe) was found to vary more based on sales channel mix than firm size, the opposite occurs for last mile back-end fulfilment (LMBF). Moreover, last mile consumer steering (LMCS) was found to vary only with sales channel-mix. Unexpectedly, primarily store-based retailers capitalize on their stores while offering competitive remote services; they hence compete indirectly with their existing store network.

Originality/value

While most prior work has focused on LMBF and LMDe for strategizing, the consumer-steering aspect seems to have been a missing link. This study develops an integrated framework for LM strategy planning, incorporating LMCS, LMBF and LMDe. New aspects such as the environment, specialization and inventory management are included. The findings provide insights for executives when strategizing, undertaking competition analysis and positioning the firm.

Chemical and electrochemical measurements were used to study the corrosion inhibition of aluminium in distilled water using one of pyridine derivatives as corrosion inhibitor.

Abstract

Purpose

Chemical and electrochemical measurements were used to study the corrosion inhibition of aluminium in distilled water using one of pyridine derivatives as corrosion inhibitor.

Design/methodology/approach

Corrosion inhibition of aluminum in distilled water was investigated in the absence and presence of different concentrations of 2,6-di methyl pyridine (DMP). Potentiodynamic polarization, open circuit potential and Fourier Transform Infrared Spectroscopy were employed.

Findings

Inhibition efficiency of 86 per cent is reached with 0.0187 M of DMP at 25°C. Potentiodynamic polarization showed that DMP behaves as mixed type inhibitor. The inhibitor obeyed the Langmuir adsorption isotherm. The value of ΔG°ads suggests physico-chemical adsorption of the inhibitor molecule on the aluminium surface.

Originality/value

This paper indicates DMP could be used as corrosion inhibitor to prevent the corrosion of aluminium in in distilled water.

Abstract

Purpose

In this study, electrochemical deposition method which have cheaper equipment than thermal spraying methods and is available for the production of composite coatings were used.

Design/methodology/approach

Composite coatings were electrodeposited from a Watts's bath solution in which the suspended Cr3C2-NiCr particles were dispersed in the bath solution during deposition. Potentiodynamic polarization and electrochemical impedance spectroscopy techniques have been used to evaluate the corrosion resistance of the composite coating in the 3.5 Wt.% NaCl solution.

Findings

It was found that the submicron Cr3C2-NiCr particles distributed uniformly in the coating and depend on the current density of deposition, different amount of particles can be incorporated in the coating. The results showed that the corrosion resistance of the Ni/ Cr3C2-NiCr composite coatings is more comparable to the pure nickel coating.

Originality/value

Production of Ni-base composite coating from an electrolytic bath containing Cr3C2-NiCr particles is possible via electrodeposition.

Abstract

Purpose

Study of corrosion behaviour could benefit from quantum chemical calculation to investigate the role of adsorption of main anions such as OH and Cl on metallic surfaces. The purpose of this study is to report the quantum chemical study of aluminium immersed in NaOH, NaCl and HCl solutions and verifying the calculations by potentiodynamic and open-circuit potential (OCP) measurements.

Design/methodology/approach

The electrochemical evaluations based on potentiodynamic polarization and OCP experiments were carried out. For theoretical investigations, the quantum chemical calculation was performed. In this regard, the adsorption of Cl, OH and H+ on aluminium surface was investigated. Furthermore, the natural bond orbital for the direction and magnitude of charge transfer interactions was calculated.

Findings

The calculations indicate that higher interaction energy between ions with the metallic cluster being modelled together with natural bond orbital calculations of direction and magnitude of charge transfer accurately predicts corrosion.

Originality/value

This paper shows that ions such as Cl, OH and H+ cause the corrosion of aluminium in NaOH, NaCl and HCl environments. The overall theoretical data corroborate with experimental results.

Abstract

Purpose

The purpose of this paper is to critically evaluate whether or not greening efforts are dependent on a higher level company-wide sustainability strategy to be carried out and whether or not greening efforts lead to any changes in logistics effectiveness and logistics efficiency.

Design/methodology/approach

The paper is based on empirical data collected via a survey sent to logistics managers and transport purchasers at Nordic multinationals. The results were analysed using structural equation model as to validate the anticipated relationships between the designed constructs.

Findings

Within this research, the authors have tried to validate the existence of relationships between a company's sustainability strategy, its transportation greening efforts and logistics performance.

Research limitations/implications

The paper investigates the possible effect the sustainability strategy of the firm will have on its decision to green its transportation, and the possible effect these measures will have on logistics efficiency and effectiveness. The empirical data gathered for this research are regionally restricted to the Nordic region. Further research could empirically test these relationships with empirical data from other countries or industries, perhaps using other performance constructs, to see if the results hold true.

Practical implications

It is shown that companies with a sustainability strategy are focusing on greening their transportation both from purchasing and operations perspectives to improve their entire environmental performance. The results from this paper fail to support the assumption that company-wide sustainability strategies are imperative for supply chain greening.

Originality/value

The paper is among the first attempts in analysing the relationships between a company's sustainable strategy and its logistics performance through greening the transportation activities.

Abstract

Purpose

The purpose of this paper is to explore how postponement is applied in retailing and how such application is connected to logistics flexibility.

Design/methodology/approach

An overview of the established typological classifications of postponement and logistics flexibility is presented followed by empirical results from three case studies of retailers of electronics, furniture, and grocery in Sweden. The study relies on primary qualitative data gathered on the retailers as well as secondary material on some suppliers including logistics providers for further insight.

Findings

The results of the study show that retailers have different practices when it comes to postponement and speculation; however, there is a growing tendency toward postponement among retailers by exploring new means of applying postponement. The results reveal that retailers that have higher application of postponement seem to be more flexible in their logistics operations.

Research limitations/implications

The paper provides direction for further empirical research of the topic, by indicating the application of postponement is not constrained to the point of purchase and could be extended by involving consumers as well as capitalizing on suppliers’ competences and capabilities. Especially, sales services, software, and upgrades could provide opportunity for further expanding the concept.

Originality/value

The paper contributes to the existing literature on logistics practices of postponement and speculation, as well as logistics flexibility by focussing on retail firms in Sweden. Most of the prior scholarly work on postponement and flexibility is on the manufacturing context.

Abstract

Purpose

There is a lack of consensus in conceptualizing and defining logistics flexibility as a distinct construct among supply chain scholars. The purpose of this paper is to systematically analyze the existing literature on logistics flexibility.

Design/methodology/approach

By taking a systematic approach to literature review, a total of 100 academic articles were content analyzed. As a general framework, the classification broadly provided by Zhang et al. (2002, 2003, 2005, 2006) was applied in order to increase the consistency and validity of the review.

Findings

The results show that logistics flexibility has gained an increasing academic attention in the past two decades in terms of the number of published articles. First, the various terminologies often used in relation to logistics flexibility are explored. Second, the definitions of logistics flexibility at various levels of analysis are presented along with methodological considerations of the current literature. It is shown that most of the existing articles claim to study the matter at the chain level. The main methodological tools used in studying logistics flexibility are revealed as well as the fact that the majority of the empirical studies correspond to the manufacturing industry. Moreover, a synthesis of the principal measures used to gauge logistics flexibility is provided. Finally, current and emerging themes in logistics flexibility research are highlighted. The study also underlines the main measures used in studying logistics flexibility.

Research limitations/implications

This paper only focusses on academic articles published in journals and does not include other contributions such as books, etc. The systematic literature review facilitates further conceptual and empirical studies; however, more narrative literature reviews could complement the results of this study.

Originality/value

This paper is unique in the sense that it specifically reviews the literature on logistics flexibility in a systematic fashion. The content analysis has been carried out using NVivo 10 enabling the systematic nature of the review as well as increasing the pedagogical value of the method.
