Abstract
Contractor selection models have been developed for large scale works with the assumption of the availability of contractor’s information for the clients. However, a similar study of small building works, especially building maintenance and repair works, is almost ignored. In light of the small amount of work, the employment of building consultants for the selection of contractors in small works is often not feasible, and the cost of acquiring the contractor’s information is often prohibitively high. This research uses case studies to show that a contractor selection model for large scale works does not perform well in small works without the advice of the consultant. The high proportion of specification costs in small works contracting deters the detailed design and documentation stage. A wider variation of tender sums is therefore expected and revealed in the case studies. This paper reviews the building procurement mechanism in small building works in Hong Kong and argues that the employment of a property management agent is conducive to the contractor selection process. Accordingly, further investigations are warranted for a contractor selection model for small building works.

Abstract
As organizations have expanded globally, control mechanisms utilized in the past may need to be supplemented with a new type of personnel, that of the inpatriate. Expatriates were the most widely used staffing for corporate control, but due to various issues, a complementary set of employees to facilitate corporate goals could be utilized. Inpatriation, as a practical and conceptual means to augment expatriation, is discussed, compared with, and contrasted to, expatriation. This research explores the use of inpatriates in facilitating global control.

Abstract
Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Abstract
Purpose
Fresh fruits and vegetables (FV) are crucial global food resources, but the presence of heat loads during harvest adversely impacts their shelf life. While freezing technology provides an effective means of removing heat loads, it is an energy-intensive process and may consequently prove too costly for practical business viability. The growing interest in utilizing magnetic field (MF) technology during the freezing of fresh FV enhances the freezing rate and rapidly removes the heat loads of products.
Design/methodology/approach
In the present study, pulsed magnetic field (PMF) pretreatment employing specific field strengths (9 T, 14 T and 20 T) was examined as a preliminary step before freezing mango and tomato and compared to the conventional freezing method (untreated) at − 18 °C.
Findings
PMF pretreatment prior to freezing demonstrated a noteworthy enhancement in freezing rate by around 10 and 12% when compared with the conventional (untreated) freezing, which exhibited freezing rates of −0.08 °C/min and −1.10 °C/min for mango and tomato, respectively. The PMF pretreatment (at 20 T) provided a higher freezing rate (at p = 0.05) than the conventional freezing method reduced heat loads amounting to 1.1 × 107 J/kg oC and 2.9 × 106 J/kg oC, significantly (at p = 0.05) from mango and tomato, respectively. These reductions in heat loads were approximately more than 5% of the calculated heat loads removed during conventional freezing.
Research limitations/implications
Mango and tomato samples were only tested; the results may lack generalizability. Therefore, researchers are encouraged to test for other products for further studies.
Practical implications
The paper includes implications for the development of a rapid freezing technique, the development of “pulsed magnetic field” and for eliminating the problem associated with conventional (slow) freezing.
Originality/value
The study holds significance for the production of postharvest freezing technology, providing insightful information on the PMF-assisted freezing of cellular foods.

Abstract
We have conducted a study of academic faculty use of databases for research, their need for evaluative guides to databases, and the appropriateness of currently‐available guides. Although the response rate was low (19%), the follow‐up survey suggested only a minimal non‐response bias. Our findings suggest that academic faculty are typically unaware of the range of databases available and few recognize the need for databases in research. Of those faculty who do use databases, most delegate the searching to a librarian or an assistant, rather than performing the searches themselves. We identified thirty‐nine database guides; these tend to be descriptive rather than evaluative.

Abstract
This study assessed the contribution of containerization to the development of Western Ports, Lagos Nigeria. The aim was to assess the influence of containerization on some indices of port development such as port infrastructure development, ship turnaround time, cargo dwell time and congestion. Questionnaire was used to gather information on the contribution of containerization to change in maritime trade in the country, the influence of containerization on terminal expansion, congestion, level of investment in container port infrastructure as well as the influence of such investment on container dwell time and ship turnaround time (TAT) and the competitiveness of container terminal within Nigeria port systems and with other developed container ports of the world. Secondary data used included statistics of reports of operations of Western Ports between 2000 and 2010 as reported by NPA, as well as reports of some selected ports derived from Containerization International Year Book, which were used in this study for the sake of global reference. Summary tables and ANOVA for the analysis of the data. Results revealed a significant contribution of containerization to maritime trade relative to the ports’ annual records but with no significant influence on ship turnaround time, cargo dwell time congestion which are determinants of port productivity and competitiveness. The study concluded that Western Ports have still not reaped gains of containerization and lacking in competitiveness when compared with other developed ports of the world.
