Abstract

Purpose

Healthy diets need to be coupled with an active lifestyle and other healthy behaviors to achieve and maintain bone health across the life cycle. The purpose of this paper is to focus on several nutrients that aid skeletal development in early life and help promote healthy bone and prevent or delay osteoporosis in late life in both males and females.

Design/methodology/approach

The paper is a brief review of recent findings linking diet and bone health.

Findings

Skeletons of both females and males benefit from reasonably sufficient intakes of calcium, phosphate, vitamin D, and other bone‐related nutrients and phytochemicals, but excessive amounts, especially via supplements, may not help bone and they may even have adverse effects, such as promoting arterial calcification.

Research limitations/implications

Trials are needed to establish with certainty that calcium intakes beyond the recommended intakes do not protect against hip and vertebral fractures and may contribute to arterial calcification.

Originality/value

Maintaining bone health, especially late in life, helps prevent or delay hip fractures, devastating events that are life threatening, especially in women, but excessive calcium may not be healthful.

Abstract

Purpose

The intent of this review is to provide a nutritional background for the hypothesis that excessive intakes of calcium and, possibly, vitamin D in adults and the elderly may contribute to an increased risk of cardiovascular diseases.

Design/methodology/approach

Recent scientific reports and literature reviews on the linkage between excessive dietary calcium consumption and cardiovascular calcification have been assessed. Prospective human data on this health concern is limited to one recent report from New Zealand of elderly women on calcium supplements for five years. Other supporting evidence is derived from experimental studies over the years and from observations of subjects with gastric ulcers who consumed excessive amounts of milk along with antacids and of “worried well” subjects who took excessive calcium supplements or yogurt.

Findings

Calcium loading in arterial walls occurs under these conditions, even among those with healthy renal function, because atherosclerotic plaques in arterial intimal layers readily permit calcium uptake from blood and the formation of bone in inappropriate locations throughout the body, especially in coronary arteries, heart valves, and arteries of other major organs. Arteriosclerotic damage in affluent populations, such as the USA, is common. Bone health seems to benefit little from excessive calcium in late life compared to the damage to arterial function.

Research limitations/implications

Future studies are needed to advance understanding of this diet‐disease linkage.

Originality/value

This review supports recent data that indicates an important relationship between excessive calcium intakes and arterial calcification in adults and the elderly.

Abstract

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

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

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.
