The present study examines the struggle for hegemony in the public sphere by two different systems, following Hong Kong’s handover to China in 1997. It has been postulated that the new media, particularly social media, has become an important public sphere for the citizens of Hong Kong to engage in an anti-hegemonic struggle against China’s discursive encroachment into Hong Kong since 1997. Given that the public platform provided by legacy media has been bought out or coopted by China, new media has begun to serve as a subaltern public sphere to enable resisting the hegemony imposed by China. This was analyzed through a survey conducted as part of this study, which showed that people who are young, read the Apple Daily, have high expectations of local autonomy, and a high regard for press freedom are prone to using social media to obtain their social and political information. This article analyzes the implications of the emergence of a counter-China hegemonic public sphere. 相似文献

We study the problem of (off-line) broadcast scheduling in minimizing total flow time and propose a dynamic programming approach
to compute an optimal broadcast schedule. Suppose the broadcast server has k pages and the last page request arrives at time n. The optimal schedule can be computed in O(k3(n+k)k−1) time for the case that the server has a single broadcast channel. For m channels case, i.e., the server can broadcast m different pages at a time where m < k, the optimal schedule can be computed in O(nk−m) time when k and m are constants. Note that this broadcast scheduling problem is NP-hard when k is a variable and will take O(nk−m+1) time when k is fixed and m ≥ 1 with the straightforward implementation of the dynamic programming approach.
The preliminary version of this paper appeared in Proceedings of the 11th Annual International Computing and Combinatorics
Conference as “Off-line Algorithms for Minimizing the Total Flow Time in Broadcast Scheduling”. 相似文献

The primary purpose of this study was to empirically examine whether or not informational impediments impair or alter decision making, with specific focus on capital budgeting decisions. Based on detailed interviews of senior corporate executives, it appears that management information systems (MIS) are less than adequate in providing the information items required to utilize the non-naive methods of capital budgeting. It is therefore suggested that the MIS concept be vastly broadened in regard to such decisions. 相似文献

The authors examine alliances involving inter-firm co-operation which they term ‘multi-point alliances’. These are first defined and considered in varying degrees of complexity. A typology of multi-point alliances is produced, and interviews conducted with French and Spanish corporations followed by a two-stage questionnaire survey of France's largest corporations. The dynamics of multi-point co-operation were then examined. The results include support for the authors' research hypothesis that both business complexity (scope) and organizational complexity (structure) impact the evolution of co-operation: the higher the complexity, the more likely the co-operative arrangement will diverge from its initial objective. 相似文献

Leadership research has recently begun to emphasize the importance of examining the level of analysis (e.g., individual, dyad, group, organization) at which phenomena are hypothesized to occur. Unfortunately, however, it is still not commonplace for theory to clearly specify, and for investigations to directly test, expected and rival level-of-analysis effects. This article first selectively reviews a cross-section of theories, models, and approaches in leadership, showing generally poor alignment between theory and the level of analysis actually used in its testing. A multiple levels of analysis investigation of the Leader–Member Exchange (LMX) model is next presented. This theory has as its foundation the dyadic relationship between a supervisor and his or her subordinates. Yet, less than 10% of published LMX studies have examined level of analysis—and none has employed dyadic analysis. Using within- and between-entities analysis (WABA) and two different samples, four LMX level-of-analysis representations are tested, which involve monosource data; three of these models are then tested using heterosource data. Overall, good support is found for the LMX approach at the within-groups and between-dyads levels. Implications for aligning theory with appropriate levels of analysis in future research are considered. 相似文献

We propose a generalization of expected utility that we call generalized EU (GEU), where a decision maker’s beliefs are represented by plausibility measures and the decision maker’s tastes are represented
by general (i.e., not necessarily real-valued) utility functions. We show that every agent, “rational” or not, can be modeled
as a GEU maximizer. We then show that we can customize GEU by selectively imposing just the constraints we want. In particular,
we show how each of Savage’s postulates corresponds to constraints on GEU. 相似文献
