This article is geared toward shedding some more light on what may be the next space race and its contours.Space flight is undoubtedly a human achievement of the second half of the 20th century, and probably the most audacious one of the past century. The space race started suddenly in the 1950s and has grown explosively during the following two decades, but decreased steadily after the 1970s. After the 1990s, however, we have seen a shy rebirth of space-related activities, when many other actors (states) entered the stage, adding up to the agonizing role of the two-actor piece that we have witnessed during the so-called Cold War.The opening years of the 21st century provided a more complex narrative for space exploration. At the start of the new millennium a new technosphere [1] emerged, dominated by what is used to be called as the Information and Communications Technologies (ICT), with the Internet playing the leading role among the bandwagon of technological novelties that appeared during the twilight of space activities. In despite of the fact that artificial satellites represent the very backbone of the global communications system, space activities seem to play a secondary role amidst the apparently accelerated rate of change concerning the technological systems of the present technosphere. But, as it is demonstrated in this paper, things are changing, and very probably a renewed space race will unfold in the coming decades.A question may be placed: what happened? Why the Earth stood still with regard to the race toward the cosmos? Answer: futurists, even prestigious ones like Herman Kahn and Arthur Clarke, did not consider the existence of socioeconomic long waves (Kondratieff waves, or K-waves for short) with their two decades long economic downturn, which has contributed to the deceleration of space-related activities.Analyzing the worldwide evolving scenario of space-related activities during the last eighty years under the framework of the succeeding K-waves and applying some technological forecasting tools, namely the logistic analysis, technological surveillance and intensive data mining, scrutinizing more than 7500 events occurred in the period 1930–2010 related with space activities, it is demonstrated that the space race like the one that we have witnessed until now is a natural growth process that has saturated at the dawn of this century. The same analysis demonstrates that a new growth process in this field might be nowadays under way with contours very different from that imagined by futurists and science fiction writers sixty years ago. Also the main trends in the usage of launching vehicles and satellites are framed and discussed in this paper. 相似文献

Understanding the microenterprise sector to design a tailor-made microfinance policy for Cape Verde 总被引:1,自引:0,他引:1

Two of the central challenges faced by Cape Verde at the present are the high level of unemployment and the increasing proportion of the population living in (relative) poverty. Microenterprise development can be an effective means of addressing both problems in a developing country like Cape Verde, where microenterprises account for about 50% of employment. In this paper we provide a detailed profile of Cape Verdean microenterprises and microentrepreneurs and investigate the relationship between their characteristics and the resort to outside seed capital. We find a cluster of factors—the microentrepreneur’s age, gender, level of education and reason for being self-employed—which influence significantly the probability of being in need for external start-up capital. The policy implications of these findings for the design of a specific microfinance program for Cape Verde are discussed.

The world faces a double crisis: the food crisis and energy crisis. The agribusiness is at the center of this societal dilemma, involving aspects from the volumes of production and productivity up to the way to produce them. Furthermore, there is a discussion about the need for establishing a trade-off between production of food and energy. A central aspect regarding the way of production is on how existing resources to be used and, especially, when its degradation occurs. These discussions indicate the need for interpretation and for proposition of solutions, under a complex perspective, for this double crisis. Accordingly, this paper proposes a framework for the interpretation of complex problems and for initiatives focused on sustainability that was applied to the context of food, energy and biofuel crisis. The theoretical background comprises two theories. The first is the complexity theory, which enabled the proposition of a system to understand the reality, distinguishing and combining the several existing realities without losing the global notion; The second is the sustainability theory, which enabled the systematization of stages for the planning of more sustainable actions to operate in that context; Lastly, it was possible to infer desirable characteristics that other theories could also be included, aiming to propose solutions that are more appropriated for this specific context. 相似文献

The aim of this research is to analyse the students’ perceptions about their extramural use of English, comparing undergraduates studying their degree in English (EMI) with those studying theirs in their native language (non-EMI) within a span of five academic years. Data collected from a Spanish University suggest that the students´s interest and perception of their possibilities of working abroad in English differ. Results also reveal key differences in the use of extramural English and suggest that exposure to reading books or watching English-language films will eventually contribute to the formation of global mindset in students. The trend of the importance of English during a five year span is also considered, for both strands of students. This study makes a contribution in the field of teaching in international business settings for high education institutions. 相似文献

The rise of the digital economy provides firms across the globe with unique business opportunities. Companies such as Facebook, Alibaba, and Uber are competing in a new multi-sided platform world; the primary focus of these firms, from their inception, is to provide digital infrastructure, information and technology—intangible assets that enable direct interaction or value creation across platforms by linking different user group and complementors, often at the international level. Building on data drawn from multinational multisided Platform corporations (MMPCs) operating in China, we combine insights from internalization theory and network effects in understanding the value creation of such firms. We explore the boundaries of these new “breed” of MNEs in exploiting firm-specific advantages (FSAs) and in creating new knowledge between headquarters and subsidiaries. The findings suggest that internalization theory needs to shift its focus from the ‘boundaries of the firm’ to the ‘boundaries of the local network’. By integrating their internal and external networks of knowledge in adapting their business models in host markets, this new breed of MNEs is more likely than the traditional one to gain a sustainable competitive advantage in the new information age. 相似文献

This research aims to understand the process of cars' disposal, its context, its influences and its impacts on the meanings for consumers and their identities, as well as the new behaviours of these consumers when living without their car(s). We conducted, analysed and interpreted 20 in‐depth interviews with consumers that had previously owned at least one car and had no financial reasons for disposing of their car(s), but had decided to do it, and started to live without them, adopting alternative methods of transportation. Our findings show that these consumers faced a complicated process regarding the disposal of their car(s) but, due to the changes in their circumstances, they re‐signified relevant concepts that were connected to the ownership of a car: Their perception of freedom, comfort, safety and status changed during and after the disposal of their car(s). We also noticed that there were implications in terms of changes in their attitudes and behaviour as both citizens and consumers. As a contribution to the literature, our findings indicate that the re‐signifying of concepts related to possession of the object as well as changes in attitudes and behaviours that consumers undergo in the postdisposal stage, must be included in the model proposed for evaluating consumer behaviour in product disposal. 相似文献

The identification of the entrepreneurs’ characteristics and the knowledge of the entrepreneurial profile of university students
have been assuming a growing importance in the development of educational programs directed towards the entrepreneurship and
start-up processes. This study aims to identify the factors that most contribute for the intention to start up a business.
The research also tries to identify the profile of a potential entrepreneur student concerning several characteristics: personal
attributes, family, demographic variables and motivations. Research findings include the idea that entrepreneurship education
is the most relevant factor in what concerns the propensity to business creation. On the other side, personal characteristics
have an important role in shaping motivation to start-up a business and perceived hurdles have a negative impact in the intention
to start-up. The results may be relevant when developing an adequate educational program directed to the entrepreneurship
education and start-up processes. 相似文献

In this paper we analyse whether entrepreneur location decisions differ across industries and identify the factors determining the choice of location between rural and urban environments. Firm location is based on a new taxonomy developed over the influential three dimensions of Hayter’s (1997) approach. The paper uses data from sample of one thousand Portuguese firms. We present a stylized theoretical model to determine how these new five dimensions influence firm’s location and test the model through a logistic regression. Our results show that that the location decisions depend on the sector of activity, type of area (urban vs. rural) and the characteristics of the entrepreneur. We find that companies engaged in knowledge intensive business services prefer to locate in urban areas. From an institutional point of view, firms prefer to locate in rural areas. 相似文献
