The evolution of civilization appears to have primarily resulted from continuous improvement made possible by technological advances. A group of social evolutionists and economists have identified, among others, energy, transport, as well as information and communication to be the three most influential technologies. On the other hand, a number of eminent scholars have cited several forces, natural, physiological, technological, as well as environmental which can place a limit on on-going improvement.The purpose of this paper is to empirically explore the continuous improvement process as well as the limit placed on these three technologies. Using the framework of both connected and disconnected multiple technology S-curves and X-factor, historical improvement data on these three elements have been analyzed. The results of our analysis indicate that improvement in general has continued without limit mainly due to a series of emerging new technologies. These emerging technologies can be either connected or disconnected from the existing mature technologies. Our preliminary analysis shows that much of the past improvement comes from new technologies that on first serious application appear to be substantially superior from earlier technologies. In addition, enormous continuous improvement, which has accompanied both connected and disconnected new technologies appear to have played the critical role in sustaining the evolution of civilization. The paper discusses a number of policy implications and suggests topics for future research.  相似文献

In this article we propose scenario planning as a tool for fostering organizational ambidexterity. The concept of organizational ambidexterity continues to gain attention, however, clear methods for developing this organizational ability are generally not offered. We therefore describe organizational ambidexterity and situate it in the general strategy literature. Key characteristics of organizational ambidexterity are provided, and the logical link to scenario planning is made. As the concept of organizational ambidexterity is relatively novel, our proposal highlights the use of scenario planning as a potential tool for developing this organizational “skill”, and clear next steps are described to examine our proposal as well as leverage the concept of organizational ambidexterity beyond that of a simple metaphor.  相似文献

Most of the studies that describe the building of innovation capability in emerging and developing economies have focused on the ways in which latecomer firms develop continuously towards advanced capability levels along existing technological trajectories, particularly for the assembled products industries, especially in Asia. A slightly different approach is adopted herein by focusing on pathways of discontinuous capability building of firms in natural resource-processing industries. By drawing on evidence from a variety of case studies taken from 13 forestry, pulp, and paper firms in Brazil in the period 1950-2007, it was found that: (1) in contrast with the majority of case studies reported in the literature, the pathways followed by firms in their accumulation of innovation capability involved a qualitative departure from the established technological trajectory at an early stage in the development of their capability; (2) the pathways of firms along the new technological trajectories were nevertheless characterised by a high degree of variability (from intermediate to world leading innovators) in terms of the levels and speeds of the accumulation of innovation capability; (3) firms that have attained progressively higher levels of innovative performance have more rapidly developed a combination of internal and external research-based arrangements in order to undertake increasingly complex, but firm-centred innovation efforts. This paper sheds some light on some of the discussions that relate to the role of natural resources in the patterns of industrial progress and growth in those countries endowed with particular natural resource-based industries. It also provides a methodological contribution to the study of the long-term innovation strategies that make use of the dynamics of capability building, especially within natural resource-processing industries.  相似文献

A new multi-logistic methodology to analyze long range time series of evolutionary S-shaped processes is presented. It conceptually innovates over the traditional logistic approach. The ansatz includes computing the residuals to an optimized multi-logistic trend curve least squares fitted to the time-series data. The elements of the residuals series are checked for autocorrelations and once detected the residuals series is further analyzed to search for eventual presence of underlying periodic structures using a truncated Fourier sine series. The method foundations ensures both a universal applicability and a capacity to disclose the existence of active clocks that can be possibly traced to the driving motors of the evolutionary character of the time series, due to the responsiveness of corresponding process to the development of economic cycles. On associating these two views, it is found that the methodology has a strong potential to improve the quality of short-term forecasts. These findings have been put to test through applications of the methodology to studying the time evolution of two commodities of strong economic and social importance (corn and steel) and good results were consistently obtained for both the analytical and forecasting aspects.  相似文献

Proactive behavior has been indirectly linked to effective selling, an assertion underpinned by a logic, which states that in a world of high competition and choice, the passive, reactive seller is unlikely to do as well as his or her more proactive counterpart. Yet, little direct empirical evidence exists to substantiate this link. In this paper, we address this knowledge gap by describing a study that assesses the effect of proactive behavior on the performance of an industrial sales force. The paper explores the issue of salesperson performance and the construct of proactive behavior (or proactiveness). Using the Proactive Personality (PP) Scale to measure proactiveness and the line manager's subjective evaluation to indicate salesperson performance, it was found that a small but significant relationship exists. The results are discussed, with areas for future research delineated and implications for practitioners explored.  相似文献

Emerging technologies, notably, have redefined business by erasing the traditional boundaries of time and geography and by creating new virtual communities of customers, distributors and suppliers, with new demands for products and services. Are there any differences between the marketing practices of the Internet-based and traditional small firms? This paper analyses published, undisguised stories of 112 traditional and 26 Internet-based small firms in Taiwan. The research results suggest that the owner-managers of both traditional and Internet-based small firms concentrate on sales, product planning and customer relationships. However, the owner-managers of traditional small firms in Taiwan place emphasis on quality control, whereas their Internet-based counterparts concentrate more on product schedules, sales forecasts, sales control and marketing research. These results indicate that cyber entrepreneurs have higher levels of marketing education and backgrounds, conduct marketing planning periodically and frequently and perform professional marketing activities. The research findings tend to suggest that though traditional marketing tenets are still suitable in the cyber environment of Taiwan, the Internet-based small firms have to utilise innovative marketing techniques to suit and compete in the ever-changing Internet business environment.  相似文献

Many sales organizations are scrambling for success in today's intensely competitive environment. An increasing number of firms are finding that tried and true traditional selling strategies are less effective, or not effective at all. Moreover, companies are discovering that what has been an acceptable level of performance no longer is adequate for maintaining or gaining competitive advantage. Consequently, managers need to focus on alternative means through which the organization can be successful. One alternative is for sales forces to engage in discretionary effort-work activities that entail going beyond the call of duty. This paper develops propositions regarding antecedents of salesperson discretionary effort, which provide managerial direction should the propositions be confirmed.  相似文献

Managing radical innovation: an overview of emergent strategy issues   总被引:15,自引:0,他引:15  
Despite differences in definitions, researchers understand that radical innovation within an organization is very different from incremental innovation , and and that it is critical to the long-term success of firms. Unfortunately, research has also shown that it is often difficult to get support for radical projects in large firms [14], where internal cultures and pressures often push efforts toward more low risk, immediate reward, incremental projects. Interestingly, we know considerably less about the effective management of the product development process in the radical than in an incremental context. The purpose of this study is to explore the process of radical new product development from a strategic perspective, and to outline key observations and challenges that managers face as they move these projects to market. The findings presented here represent the results of a longitudinal (since 1995), multidisciplinary study of radical innovation projects. A multiple case study design was used to explore the similarities and differences in management practices applied to twelve radical innovation projects in ten large, established North American firms. The findings are grouped into three high-level strategic themes. The first theme, market scope, discusses the challenges associated with the pursuit of familiar versus unfamiliar markets for radical innovation. The second theme of competency management identifies and discusses strategic challenges that emerge as firms stretch themselves into new and unfamiliar territory. The final theme relates to the people issues that emerge as both individuals and the project teams themselves try to move radical projects forward in organizations that are not necessarily designed to support such uncertainty.A breadth of subtopics emerge within and across this framework relating to such ideas as risk management, product cannibalization, team composition, and the search for a divisional home. Taken together, our observations reinforce the emerging literature that shows that project teams engaging in radical innovation encounter a much different set of challenges than those typically faced by NPD teams engaged in incremental innovation.  相似文献

The Low-Income Home Energy Assistance Program (LIHEAP) is a federal block grant program to help low-income households pay their heating and cooling bills. If the regular fiscal year LIHEAP appropriation is less than or equal to $1.975 billion, then a 1981 formula is applied to distribute funding across states, while if appropriations rise above the $1.975 billion threshold, a 1984 formula is applied in conjunction with two hold-harmless provisions. In 18 of the past 20 years, the 1981 formula has served as the default mechanism to distribute LIHEAP funding. The purpose of this paper is to call attention to the inadequacy of the 1981 formula and to explain why the objectives of LIHEAP are not met when this formula is used. We explain why the distribution of LIHEAP funds is not proportionate to the need for assistance and offer some suggestions for improvement. The 1981 formula is shown to be the outcome of a convoluted political process heavily biased in favor of cold-climate states, with cold-climate states receiving on-the-order of at least $150 million a year in allotment dollars beyond their “fair share” of heating requirements. The 1981 and 1984 distribution formulas are derived and a critical examination of each formula is presented. The 1984 formula is shown to be an ideal mechanism to distribute LIHEAP funds, based on a scientific and rational understanding of low-income energy needs, but legislative constraints prevent its application.  相似文献

La relation entre i'état et le développement social peut entre analysée à partir de trois niveaux interconnectés:
  • 1 Au niveau de la théorie et de la méthodologie. C'est ce que font Lojkine et Pahl.
  • 2 A un niveau général, mais concernant des types théoriquement differenciés d'organisations sociales (c'est à dire, sociétés capitalistes avancées, sociététés socialistes. etc.). C'est le niveau qui concerne cet auteur le plus.
  • 3 Au niveau d'une société donnée, durant une période historique déterminéee. C'est à ce niveau que les autres travaux de Lojkine ont été faits.
La critique faite par Pahl des perspectives marxistes est rejetés comme étant superficielle, par contre il est reconnu que i'?uvre de Poulantzas manque de perspective historique et dialectique. Mais i'analyse marxiste des institutions politiques dépend d'une interprétation correcte de la relation entre structure et superstructure, et ce point est développé par i'auteur. Une critique est faite des théories élitistes et historicistes. La typologie historiciste de Runciman est considérée comme étant inadéquate, car elle ne peut ětre appliquée à la réalité historique, et en dernier lieu, ne peut expliquer pourquoi les relations état-société montrent tant de variations. Les définitions marxistes de i'état sont insuffisantes et ont besoin d'ětre dévéloppées. A propos, les travaux de Lojkine et de Poulantzas sont critiqués comme étant réductivistes et non-dialectiques. La question des origines sociales de la démocratie est introduite afin de développer une perspective analytique satisfaisante qui pourrait prendre en compte les faits historiques des révolutions nationales en Europe de l'Ouest, au Japon et aux Etats-Unis. L'accent est mis sur le role de la classe ouvrière, le concept d'hégémonie, l'exercise du pouvoir hégémonique, et plus précisement quand la classe hégémonique n'est pas dominante. Une bonne analyse marxiste des relations état-société doit pouvoir envisager les tendences et les conditions actuelles de l'accumulation du capital, en conjonction avec les intérěts des groupes monopolistes. Cet essai fini par une brěve discussion des tendences actuelles dans ces domaines.  相似文献
