Abstract

Purpose

The purpose of this study is to evaluate the nutritional effects in Wistar rats of supplementation with stand-alone saturated fatty acid (SFA) or monounsaturated fatty acid (MUFA), the replacement of SFA by MUFA and the combination of both (SFA + MUFA) over a long period of time (13 weeks).

Design/methodology/approach

In total, 30 Wistar rats were used and randomly assigned to receive (n = 6): control – lab chow; lard (L20%) – lab chow with added lard (20%); olive oil (O20%) – lab chow with added olive oil (20%); lard replacement with olive oil (L20% –O20%) – during six weeks lab chow with added lard (20%) replaced by lab chow with added olive oil (20%) given during the past seven weeks of the trial; lard combination with olive oil (L10% + O10%) – lab chow with added lard (10%) and olive oil (10%). Food and caloric intake, weight gain, food and energy efficiency, body mass index, bone mineral composition and blood biochemistry were evaluated.

Findings

All diets with added fatty acids showed higher energy intake (p < 0.001), weight gain (p = 0.01), accumulation of adipose tissue (p = 0.02) and food and energy efficiency (p = 0.01) compared to the control group. All groups exhibited higher levels of blood triglycerides compared to the control group (p = 0.02). In addition, the L10% + O10% group developed hyperglycemia (p < 0.001); the L group showed higher amounts of non- high density lipoprotein (HDL-c) (p = 0.04); and the L20%−O20% group exhibited high levels of the triglyceride/HDL-c ratio (p = 0.04) in relation to the control.

Originality/value

These results indicate that regardless of the fatty acid type, consumption in large quantities of fatty acids for long periods of time can cause obesity and dyslipidemia.

Abstract

An understanding of JIT is needed before a successful strategy can be developed. Reading, discussion and evaluation of experience are the starting‐points. A total JIT framework can then be developed and individual elements identified and defined. An integrated socio‐technical approach secures numerous benefits from successful implementation. People are the integrators and facilitators. An implementation analysis technique is proposed with actual results recorded. A pilot installation improves the prospect of success. The text draws on the experience of the writer during the development of JIT at Cummins Engine Company.

Abstract

If a bearing is carefully handled and correctly mounted, efficiently sealed and properly lubricated, then every cause of damage except one—fatigue— is eliminated. Thus the life of an individual bearing is defined as the number of revolutions that the bearing can make without signs of fatigue damage appearing on any of the rolling surfaces.

Abstract

Purpose

Given the critical consequences of the current Coronavirus (COVID-19) crisis worldwide, displaying good leadership has been of utmost importance. Hospitality has been among the industries that have been hit the hardest by the pandemic, and it requires exceptional leadership skills unique to this crisis and sector. This multi-country study aims to contribute to the understanding of some of the most important skills and strategies that leaders in the hospitality industry may use to navigate the COVID-19 crisis effectively.

Design/methodology/approach

This paper employs a qualitative study. Semi-structured interviews are conducted with managers of international hospitality groups or local hotel chains in seven different countries.

Findings

The results show that positive thinking, decision-making, flexibility, divergent thinking, trust-building and communication skills have a positive impact on leadership effectiveness in the hospitality sector during the pandemic. Besides, saving payroll costs, elaborating contingency plans and leveraging from partners' strengths are highlighted as crucial strategies.

Practical implications

This paper provides hospitality professionals across borders preliminary insights and recommendations to manage the COVID-19 crisis.

Originality/value

Especially being one of the sectors that have been hit the hardest by the COVID-19 crisis worldwide, the dynamics and leadership requirements of the hospitality sector need further attention. The findings contribute to the literature by illustrating how managers have navigated the initial stages of the crisis in the under-researched hotel sector, and also by gathering evidence about the sector dynamics related to the early stages of this crisis.

Abstract

WHEN a rolling bearing is damaged as a result of fatigue, spalling occurs cither on the ring tracks or on the surface of rolling elements. As a roller or a ball rolls over these spalls, which are depressions in the surfaces of the rings also known as flaking, impacts occur.

Abstract

SELECTION of the most suitable bearing type for a particular duty can pose a difficult problem due to the wide range of bearings available. To assist the designer these notes describe the more‐frequently‐used types of ball and roller bearings and their components, and refer to some of their uses and limitations.

Abstract

Purpose

Empirical evidence indicates that effective management of resources to implement strategy in a balanced scorecard (BSC) system is essential. We present a mathematical model for allocating limited resources in the BSC strategy implementation process.

Methodology/approach

The proposed facilitated negotiation model provides a systematic approach to prioritizing strategic initiatives in the design and implementation of a BSC.

Findings

Our joint decision model prioritizes strategic initiatives and concurrently calculates the optimal (or approximately optimal) set of BSC targets and weights, given multiyear resource restrictions.

Practical Implications

The model assumes full, open, and truthful exchange of information between the parties; an assumption that may exclude many organizations.

Social Implications

We address an important gap in the BSC literature on how organizations can effectively link strategy to the potential constraint of resource budgets.

Originality/value

Quantitative models are being used in practice for allocating resources, but we are not aware of their use by organizations for allocating resources in a BSC application.

Abstract

A NEWLY patented measuring method for detecting damage in ball and roller bearings used in machinery and transport equipment at an early stage was announced and demonstrated at a press conference in Stockholm recently by the SKF Group. The bearings are inspected in operation using the SKF shock pulse meter MEPA 10A which is to be sold by SKF.

Abstract

Purpose

This research aims to identify and measure the correlations between building information modelling (BIM) and lean construction (LC) principles at the design and construction phases.

Design/methodology/approach

The study investigates BIM-LC principles correlations using the Istanbul Grant Airport (IGA) as a case study. The Delphi technique, performed quantitatively, contributes to the identification and quantification of a set of correlations between 11 selected BIM uses and 13 LC principles, which are supported with practical examples from the case study.

Findings

Together, the two research methods provide an evidence-based approach to understand the correlations between BIM and LC. The correlation analysis results in 46 correlations, and the correlations between the LC principles and BIM uses are intensified with the LC principles.

Practical implications

A quantitative understanding BIM use and LC principles correlations and appreciation of their specific uses can guide the practical implementation of BIM and LC, especially in large and mega projects.

Originality/value

BIM and LC practices represent approaches to improve performance in construction projects. While BIM has both information technology (IT) and process perspectives, the LC approach is mainly a process and product-oriented philosophy for project efficiency, effectiveness and the elimination of non-value-adding activities and waste. Many studies have investigated how the two approaches complement each other and concluded that their combined implementation in projects can improve efficiency and effectiveness. However, to date an analytical and granular investigation identifying and measuring correlations between BIM and LC based on empirical data is lacking. This paper fills that gap with an evidence-based analysis of the tightness of coupling and correlations between BIM uses and LC principles.
