Abstract
Presents over sixty abstracts summarising the 1999 Employment Research Unit annual conference held at the University of Cardiff. Explores the multiple impacts of globalization on work and employment in contemporary organizations. Covers the human resource management implications of organizational responses to globalization. Examines the theoretical, methodological, empirical and comparative issues pertaining to competitiveness and the management of human resources, the impact of organisational strategies and international production on the workplace, the organization of labour markets, human resource development, cultural change in organisations, trade union responses, and trans‐national corporations. Cites many case studies showing how globalization has brought a lot of opportunities together with much change both to the employee and the employer. Considers the threats to existing cultures, structures and systems.

Abstract
Purpose
The purpose of this paper is to separate and purify flavonoids from glycyrrhiza by macroporous adsorption resin (MAR) mixed-bed technology.
Design/methodology/approach
The adsorption performance of MAR and MAR mixed bed for flavonoids was studied using ultraviolet-visible spectrophotometry.
Findings
The research shows that the MAR mixed bed of LZ-50+LZ-59 with a mass ratio of LZ-50:LZ-59(m:m) = 1:1 was the optimized combination with the optimal conditions of adsorption (pH = 6, T = 45°C) and desorption (liquid ratio R = 70%, T = 50°C, pH = 8) obtained, relatively.
Originality/value
This paper provides a novel way to separate flavonoids from glycyrrhiza. Under the optimal conditions, the adsorption rate (F) of MAR mixed-bed LZ-50+LZ-59 to the flavonoids was 62.5 per cent/g, the desorption rate (D) was 89.23 per cent and the purity was achieved at 80 per cent.

Abstract
Purpose
The purpose of this paper is to separate and purify flavonoids existing in the leaves of Sophora japonica by a novel method, macroporous adsorption resin (MAR) mixed-bed technology, and the optimal MAR mixed bed was screened based on the adsorption experimental result with the order of single, two, three and four MAR mixed bed separately.
Design/methodology/approach
The adsorption performance of MAR and MAR mixed bed for flavonoids was studied using ultraviolet – visible (UV-VIS) spectrophotometry.
Findings
This research showed that the MAR mixed bed of LZ-54 + LZ-67 with a mass ratio of mLZ-54:mLZ-67 = 1:1 was the optimized combination with the optimal conditions of adsorption (volume V = 140 mL, pH = 5, T = 35°C) and desorption (liquid ratio R = 50 per cent, T = 30°C, pH = 6) obtained, relatively.
Practical implications
This study aims to find an efficient way of separating flavonoids and other components that are useful for human health from Sophora japonica, which is complying with the policy of sustainable development.
Originality/value
This contribution provided a novel way to separate flavonoids from Sophora japonica. Under the optimal conditions, the adsorption rate (F) of MAR mixed bed LZ-54 + LZ-67 to the flavonoids was 63.65 per cent, the desorption rate (D) was 87.31 per cent and the purity was dramatically achieved at 58.17 per cent from 17.67 per cent after a round of adsorption/desorption operation.

Abstract
Purpose
This paper aims to evaluate the separation and purification characteristics of flavonoids from polygonum cuspidatum (PC) extracts by using macroporous adsorption resins (MAR) mixed bed to improve the utilization rate of flavonoids.
Design/methodology/approach
Taking the separation performance of flavonoids as an evaluation index, the best MAR were screened from 31 sorts of MAR and combined the best MAR to form a MAR mixed bed for adsorption and separation of flavonoids.
Findings
By studying the separation conditions that affect flavonoids, the results showed that resin LZ-72 has best separation and purification effect on flavonoids under the optimal adsorption and desorption conditions, the purity of the obtained flavonoid compound reaches 82.50%, 2.66 times of the initial extract, and the recovery rate reaches 89.70%. Theoretical research results have shown that the adsorption of flavonoids by MAR conforms to the pseudo-second-order kinetics and Freundlich models.
Practical implications
Because the flavonoids in PC have great medicinal value, the purpose of this work is to develop a method of separating and purifying flavonoids from PC, which will provide a certain foundation for the development of medicine.
Originality/value
This contribution provided a novel way to separate flavonoids from PC. Under the optimal conditions, the content of flavonoids in the product was increased 2.66-fold from 31.01% to 82.50%, and the recovery yield was 89.70%.

Abstract
Purpose
The purpose of this paper is to compare three cultural approaches from anthropology and business literature: National Culture Approach (NCA), Corporate Culture Approach (CCA), and Transactional Culture Approach (TCA). The author grounds these approaches in different epistemological standpoints and locate them at different positions on the unity-infinity continuum. The author outlines their strengths and weaknesses, and offer the Douglasian Cultural Framework (DCF) as a transactional tool for cultural sense-making.
Design/methodology/approach
Reviewing conventional NCA/CCA frameworks reveals that while their simplicity renders them attractive to users, their assumption of stable, internally homogenous and coherent cultures has its limitations. Conversely, reviewing anthropology-based TCA literature reveals that while TCA overcomes some limitations of NCA/CCA frameworks, it also has its weaknesses – it overemphasizes “self-interest” as the preferred form of rationality, and some TCA scholars render cultural comparisons impossible by supporting cultural infinity. Finally, examining DCF reveals that it overcomes some limitations of NCA/CCA frameworks, while simultaneously advancing TCA. Nevertheless, DCF too has limitations which are also exposed.
Findings
Most NCA/CCA scholars support the “unity” argument of culture, while some transactional scholars support the “infinity” argument. DCF finds a perfect balance between the two through “constrained relativism”. Also, since DCF focuses on human transactions, it is not limited in its applications to specific levels and scales. It can therefore be applied to scenarios spanning across levels and scales. Finally, it offers a compromise between the differentiation and fragmentation perspectives of corporate culture, and brings out the best of the interpretivist and post-modernistic traditions.
Research limitations/implications
The exposition of DCF opens up new avenues for research which have hitherto remained unexplored for want of appropriate frameworks, for instance the UN Peace Corps., NATO, Medecins Sans Frontiers, etc.
Originality/value
By focusing on human transactions, the paper allows for a much more dynamic conceptualization of culture as compared to static NCA/CCA frameworks.

Abstract
A case study was conducted to identify and to dispel the current stereotypes in the workplace regarding Generation X and Baby Boomers. For the purpose of the study Generation X consisted of those born between 1961 and 1981, while Baby Boomers consisted of those born between 1943 and 1960. The purpose of this article was to use a custom designed survey based on the literature as the foundation to test congruence or lack of it, to address six commonly held myths presented by Paul and Townsend (1993). Furthermore it was intended to test empirical research gathered by a literature review of the stereotypes in the workplace, to better understand the profiles and factors that motivate the Baby Boomers and Generation X, in conjunction with the following independent variables: age, productivity, motivation, training, mentoring and job satisfaction. The hypothesis tested suggested that Generation Xers are more productive, more motivated, and easily trainable and exhibit higher job satisfaction levels as compared to Baby Boomers. It is important for or ganizations to recognize the limitations that stereotypes create in the workplace. As was demonstrated by the survey, Baby Boomers and Generation Xers are not dissimilar as employees; they possess more similarities than differences. Organizations need to foster an environment of respect/equity for both groups to create synergies between them to build and maintain a productive workforce.
