Abstract

Explains that the shifts of a process may be classified into a set of modes (or classifications), each of which is incurred by an assignable cause. Presents an algorithm to determine the process shift mode and estimate the run length when an out‐of‐control status is signalled by the x‐ or s chart in statistical process control. The information regarding the process shift mode and run length is very useful for diagnosing the assignable cause correctly and promptly. The algorithm includes two stages. First, the process shift modes are established using the sample data acquired during an explorative run. Afterwards, whenever an out‐of‐control case is detected, Bayes’ rule is employed to determine the active process shift mode and estimate the run length. In simulation tests, the proposed algorithm attains a fairly high probability (around 0.85) of correctly determining the active process shift mode and estimating the run length.

Abstract

Purpose

This study aims to identify the determinants of transport mode choice and the constraints on shifting freight in New Zealand (NZ) from road to rail and/or coastal shipping, and to quantify the trade-off between factors affecting shippers’ perceptions, to assist in increasing the share of freight moved by non-road transport modes.

Methodology

A revealed preference survey of 183 freight shippers, including small and medium enterprises and freight agents in NZ, is used to investigate whether freight shippers’ characteristics affect their ranked preference for attributes related to mode choice and modal shift. Additionally, a rank-ordered logistic (ROL) model is estimated using the ranking data.

Findings

The results reveal several distinct types of transport mode choice behaviour within the sample and show how the preferences for timeliness, cost, accessibility, damage and loss, customer service, and suitability vary between industry groups and business types. Also, the ROL method allows us to identify heterogeneity in preferences for mode choice and mode shift factors for freight within NZ.

The results imply that NZ shippers ranked transport time as the most significant constraint upon distributing goods by rail, while accessibility and load size were the most significant constraints upon using coastal shipping. The study also identifies how NZ shippers’ modal shift constraints vary according to the firm’s individual or logistical characteristics.

Research implications

This study informs freight transport policy makers about the needs of NZ shippers by providing quantitative measures of the intensity of preference for the various mode choice factors.

Practical implications

Those involved in freight transport have a better basis for formulating transport policy.

Abstract

Purpose

The purpose of this paper is to establish a conversation between international business and international entrepreneurship literatures by analyzing if and how international opportunities are related to the internationalization process of the firm.

Design/methodology/approach

This paper reports finding from a backward-looking longitudinal, qualitative, embedded case study of an internationalized Brazilian firm, covering all 13 foreign markets where the firm has operated over 18 years.

Findings

Modal shifts within foreign markets were rare. Over time, the firm learned how to refine, rather than change, the servicing modes within each foreign market; it also learned how to better develop internal and exploitative opportunities, manage a portfolio of servicing modes across foreign markets, and use more complex mode servicing packages. Overall, international opportunities and the internationalization process of the firm were inextricably connected.

Research limitations/implications

The authors acknowledge limitations related to the statistical generalizability of the research method and suggest that statistical validation is needed as the research on opportunities and the internationalization process of the firm progresses.

Practical implications

Internationalizing firms should carefully consider the choice of entry mode in foreign markets. They should also understand that learning is not necessarily associated with change.

Originality/value

The authors show that the internationalization process of a traditional firm can be analyzed through an opportunity lens. This means associating characteristics of international opportunities with mode continuation and modal shifts in all foreign markets where the firm operates.

Abstract

Purpose

A commonly suggested measure to make logistics greener is a shift to intermodal road‐rail transportation. Most research addresses the issue from the carrier's perspective, arguing for ways to improve the service production to better fit the shippers' demand. In this article the issue is addressed from the shipper's perspective. The purpose is to understand what contextual factors and operations changes that are possible and/or necessary for the shipper to make a fit to the current production system.

Design/methodology/approach

Six case companies selling non‐bulk, fast moving goods are examined. These firms have gone against the mainstream and shifted modes of transport. They are investigated through a multiple case‐study design.

Findings

The findings indicate that contextual factors stressed in the carrier‐focused literature, or rule of thumb decisions made by shipping logistics management, do not always clearly predict the success of a modal shift. However, some common denominators emerge among successful cases: large transport purchasing resources, high general carrier performance, low demand volatility, and centralized system control. The study also poses some propositions regarding the success of a modal shift.

Research limitations/implications

The research is qualitative in nature and thus limited to the companies and their respective logistics systems. However, the models could be further evaluated empirically through quantitative and qualitative methods alike.

Practical implications

The paper poses a number of propositions of what constitutes a successful modal shift from a shipper's perspective, based on the identified factors and operational changes.

Originality/value

Previous research on the shift to intermodal road‐rail solutions are predominantly made from a carrier's perspective. This research addresses the issue from the shipper's perspective.

Abstract

Purpose

This paper aims to develop a computer simulation processing method to simulate the mining operation of self-advancing semi-continuous mining technology and optimize the shift step of belt conveyor by using simulation modeling framework based on intelligent objects (SIMIO). The method would effectively solve the challenge of field testing such large-scale equipment.

Design/methodology/approach

The four operational modes of self-advancing semi-continuous mining technology at single bench had been illustrated. The operational system of this technology was analyzed and broken down to single units. By analyzing the time constitution of one operation cycle, the theoretical optimization model of shift step can be established and the optimization criteria is the time utilization ratio being maximum. Once the simulation flow was determined, a three-dimensional (3D) computer simulation model of this mining technology was developed by adapting the SIMIO simulating software to the theoretical model. The models were run to investigate the outputs from different operational modes using geological and mining data from East open-pit mine.

Findings

The result of these simulations showed that the four-mining-width one-shift (FMWOS) is at maximum production capacity during all operation modes. If transfer equipment is necessary, then this mode can adapt, but system will become more complex. There are minor differences between two-mining-width one-shift and three-mining-width one-shift. If transfer equipment is not necessary, then the two-mining-width one-shift can adapt during actual production.

Originality/value

The simulation results show that the proposed method can achieve the optimal shift step of a belt conveyor and effectively reduce the time loss caused by the coordination of multiple pieces of equipment while simultaneously improving operational efficiency.

Abstract

Purpose

This paper sought to uncover the intrinsic determinants of the choice of transport modes in Nigeria's capital city, Abuja, based on commuters' perceptions on different modes of transport. The ultimate goal of the study was to come up with suitable multifaceted measures to deter private car usage, while refocusing society's mind-set towards alternative forms of transport, thereby keying into some transport-related sustainable development goals (SDG) goals.

Design/methodology/approach

The study adopted qualitative methods: 320 commuters were surveyed at bus stops and car parks around the city, and respondents were identified using multistage sampling, aided by purposive/convenience sampling, and this number was reached by saturation of themes. Focus group discussions were held with eight screened public officials from relevant (transportation and environment related) agencies/unions in the city. NVivo 10 software was used to thematically analyse the data gathered from a relativist and an interpretive stand point.

Findings

The study found transport mode choice to be intrinsically more motivated by socio-economic forces serving as a basis for other socio-psychological factors. Multifaceted measures, including spatial, socio-economic, environmental and public relation measures, were found suitable to break car-use motives in the study area towards adopting alternative modes of transport, thereby achieving some transport-related SDG targets.

Originality/value

The study was unique as it looked at the intrinsic mode choice determinants from a Sub-Saharan African capital city perspective and provided suitable multifaceted best practiced measures that deemphasised car use while emphasising alternative modes, thereby shifting commuters' mind-set towards environmentally sustainable modes of transport.

Abstract

This study tested predictions derived from social psychological theorising on the deindividuation phenomenon concerning the effects of working alone or collectively on the quality of outcomes of police patrolling activity. Police officers (n = 1,118) reported the resistance experienced when they last carried out each of 12 patrol activities. Officer age, gender, rank and experience did not predict resistance experienced. Increased resistance was associated with the more active afternoon and night shifts, the presence of larger numbers of civilians, and the two (cf. one) officer patrol mode. Although the resistance experienced by officers working collectively in part reflected the influence of work shift on patrol mode, there were substantial proportions of variance in resistance for most patrol activities that could not be explained by the shift variable. The influence of collective patrolling on resistance was consistent with theorising about the origins of deindividuated behaviour, and highlighted the importance of broad conceptualisations of organisational effectiveness when evaluating individual and collective functioning.

Abstract

Many academic ankles and much analysis by the popular press and trade journals have focused on selected and rather narrow aspects of Japan's business moves in various markets of the U.S. It is argued in this paper that Japan's presence in the U.S. is based on a long‐range, multi‐strategy system. The paper analyzes Japan's long‐term business strategy in the U.S. by taking an evolutionary approach to the entry modes of Japanese companies in the United States. This approach focuses on how and why the entry modes shifted during the past three decades as a basis for understanding the changes in the character of Japan's economic presence in the U.S. and for anticipating future strategic shifts.

This paper argues for the benefits to international business (IB) of taking a much longer view at the engagement by multinational enterprises (MNEs) with host locations.

Abstract

Purpose

This paper argues for the benefits to international business (IB) of taking a much longer view at the engagement by multinational enterprises (MNEs) with host locations.

Design/methodology/approach

The authors showcase a project tracking the engagement by MNEs with Australia over the past two centuries. Extensive archival work has been undertaken to identify and document modes of entry, home countries, industries, operational modes and company types among the MNEs operating in Australia. The authors also describe the shifting nature of Australia as a host location.

Findings

The authors demonstrate the historical and ongoing diversity of ways in which MNEs interact with a host. They show that different organisational forms have prevailed over time, and that considerable operational mode changes can best be observed when a long lens is adopted. The authors show how these mode changes interact with host country dynamics, and also the broader context of the MNE and its altering strategies.

Research limitations/implications

The authors urge IB scholars to embrace longer timeframes to capture the complexity of MNEs’ growth and adaptation more meaningfully.

Originality/value

By taking such a long-run perspective, the authors shed new light on the importance of moving beyond simple snapshots to analyse key IB constructs and phenomenon.
