Social media? Get serious! Understanding the functional building blocks of social media 总被引:1,自引:0,他引:1

Traditionally, consumers used the Internet to simply expend content: they read it, they watched it, and they used it to buy products and services. Increasingly, however, consumers are utilizing platforms—such as content sharing sites, blogs, social networking, and wikis—to create, modify, share, and discuss Internet content. This represents the social media phenomenon, which can now significantly impact a firm's reputation, sales, and even survival. Yet, many executives eschew or ignore this form of media because they don’t understand what it is, the various forms it can take, and how to engage with it and learn. In response, we present a framework that defines social media by using seven functional building blocks: identity, conversations, sharing, presence, relationships, reputation, and groups. As different social media activities are defined by the extent to which they focus on some or all of these blocks, we explain the implications that each block can have for how firms should engage with social media. To conclude, we present a number of recommendations regarding how firms should develop strategies for monitoring, understanding, and responding to different social media activities. 相似文献

Based on empirical studies of firm exchange activities in business markets, this paper outlines a business network view of
the firm-market relationship, which differs fundamentally from the view assumed by neo-classical economic theory. We define
business networks as sets of connected business relationships. Thus business relationships and connections between relationships
are the critical elements in the business network view. It is assumed, as suggested by the Uppsala internationalization process
model, that an interplay between knowledge and commitment development is the mechanism that drives the relationship and network
development process. Against this background the paper discusses how strategic change is analyzed in literature on alliances
and networks. In conclusion the paper presents a set of propositions about strategy-making in business network settings. 相似文献

Adolescents are at a greater risk of being involved in traffic accidents than most other age groups, even before they start driving cars. This article aims to determine the factor structure of a self-report questionnaire measuring adolescent risky cycling behaviour, the ACBQ (Adolescent Cycling Behaviour Questionnaire). The questionnaire's structure was based on the widely used Driver Behaviour Questionnaire (DBQ). A sample of secondary school students (N?=?1749; age range: 13-18 years) filled out the questionnaire. Factor analysis revealed a three-factor structure underlying the questionnaire, which was confirmed on two equally large portions of the entire sample. These three underlying factors were identified as errors, common violations and exceptional violations. The ACBQ is a useful instrument for measuring adolescents' risky cycling behaviour. 相似文献

Forest management poses particular challenges as the pressure on forests is huge due to deforestation. In this context, the establishment of protected areas is a common conservation measure where institutions are put in place and sanctions regarding forest use are enforced. This paper focuses on the practice of sustainable forest management and the associated perspectives of local institutions at the rainforest margins of Lore Lindu National Park (LLNP) in Central Sulawesi, Indonesia. 相似文献

Summary This paper assesses how the Dutch system of occupational pensions redistributes between and within generations. The approach
in this paper deviates from the usual approach by incorporating the full life cycle in the measurements, rather than only
the annual effects. In order to quantify redistribution, we use the level of educational attainment, gender and age to classify
the pension fund population. For all groups distinguished, we measure in present value terms the average net benefit from
participating in occupational pensions. The results indicate a sizable redistribution from males to females and from low educated
to higher educated workers. On a lifetime basis, the impact of intergenerational transfers is modest.
I am grateful to the two anonymous referees, Ed Westerhout, Casper van Ewijk, Lex Meijdam, Yvonne Adema and Peter Kooiman
for their helpful comments on earlier drafts of this paper, and to Andre Nibbelink for his valuable computational assistance. 相似文献

We investigate the general structure of optimal investment and consumption with small proportional transaction costs. For a safe asset and a risky asset with general continuous dynamics, traded with random and time‐varying but small transaction costs, we derive simple formal asymptotics for the optimal policy and welfare. These reveal the roles of the investors' preferences as well as the market and cost dynamics, and also lead to a fully dynamic model for the implied trading volume. In frictionless models that can be solved in closed form, explicit formulas for the leading‐order corrections due to small transaction costs are obtained. 相似文献

Using survey forecasts of a large number of Asian, European, and South American emerging market exchange rates, we studied empirically whether evidence of herding or anti‐herding behavior of exchange‐rate forecasters can be detected in the cross‐section of forecasts. Emerging market exchange‐rate forecasts are consistent with herding (anti‐herding) if forecasts are biased towards (away from) the consensus forecast. Our empirical findings provide strong evidence of anti‐herding of emerging market exchange‐rate forecasters. 相似文献

The limited availability of high quality and computer readable data seriously impedes research in history and finance. We introduce a new monthly return series for Belgian owned equity based on Brussels Stock Market data for the period 1832–1914 as an improvement to the popular Drappier index. Over this period, our dataset includes 446,374 prices, 23,976 dividends, 371 stock and reverse splits (or other capital operations) on 2037 stocks of 1387 (foreign and Belgian) companies. Our dataset includes all shares and bonds but also high-quality information on prices, dividends, shares outstanding and market capitalization. In addition, company, country and sector information is available. We construct value weighted, price weighted and equally weighted indices as well as dividend yields. We find three important results. First, total nominal returns hover between 3.29% and 5.35% per annum, depending on how individual stocks are aggregated into the index. Second, dividend income constitutes the major part of total return and dividend distributions have a clear seasonal pattern. Third, the results highlight several drawbacks of the Drappier indices, especially an upward bias in expected equity performance. 相似文献

Previous studies already established the idea of a partnership in which HR professionals and line managers share an organisation’s HRM responsibility. Yet, this relationship is often plagued by conflicts and other obstacles. As such, a perceptual discrepancy is likely to exist between both parties on the degree of HR devolution, which may eventually lead to bad performance. Using survey data, we empirically analyse which factors may explain a perceptual discrepancy between HR professionals and line managers on the latter group’s role in HRM. Results show that the HR-line discrepancy on the degree of HR devolution is rooted in differences in perception on several other factors, including organisational support, (personnel) red tape, the line’s individual capacity and age. Overall, though, it is a matter of understanding both HR’s expectations and the line’s experiences in all aspects of their partnership. 相似文献
