Today, the Internet is growing exponentially, with traffic statistics that mathematically exhibit fractal characteristics: self-similarity and long-range dependence. With these properties, data traffic shows high peak-to-average bandwidth ratios and causes networks inefficient. These problems make it difficult to predict, quantify, and control data traffic. In this thesis, two analytical methods are used to study fractal network traffic. They are second-order self-similarity analysis and multifractal analysis. First, self-similarity is an adaptability of traffic in networks. Many factors are involved in creating this characteristic. A new view of this self-similar traffic structure related to multi-layer network protocols is provided. This view is an improvement over the theory used in most current literature. Second, the scaling region for traffic self-similarity is divided into two timescale regimes: short-range dependence (SRD) and long-range dependence (LRD). Experimental results show that the network transmission delay separates the two scaling regions. This gives us a physical source of the periodicity in the observed traffic. Also, bandwidth, TCP window size, and packet size have impacts on SRD. The statistical heavy-tailedness (Pareto shape parameter) affects the structure of LRD. In addition, a formula to estimate traffic burstiness is derived from the self-similarity property. Furthermore, studies with multifractal analysis have shown the following results. At large timescales, increasing bandwidth does not improve throughput. The two factors affecting traffic throughput are network delay and TCP window size. On the other hand, more simultaneous connections smooth traffic, which could result in an improvement of network efficiency. At small timescales, in order to improve network efficiency, we need to control bandwidth, TCP window size, and network delay to reduce traffic burstiness. In general, network traffic processes have a Hlder exponent a ranging between 0.7 and 1.3. Their statistics differ from Poisson processes. From traffic analysis, a notion of the efficient bandwidth, EB, is derived. Above that bandwidth, traffic appears bursty and cannot be reduced by multiplexing. But, below it, traffic is congested. An important finding is that the relationship between the bandwidth and the transfer delay is nonlinear.

abtract This paper uses a seasonal dependence VAR model that is proposed by Olivei and Tenreyro in the year 2007.We are to assess whether the effect of a policy exogenous shock differs according to the quarter in which the shock occur. We consider Taiwan as a small open economy with flourishing international trade; the effect of exchange rate is viewed as an important transmission channel in monetary transmission mechanism. First part, we consider domestic monetary policy shock how to influence macroeconomic variables. Second part, the United State is powerful around the world. The Fed policies whether affect Taiwan macroeconomic or not. Finally, discuss an exogenous shock on the exchange rate to impact Taiwan macroeconomic.

The 21st century is the time for network economic with hyper-competition. The well-developed information technology makes information flow smoothly among suppliers, retailers, competitors, and entrants. Thus, that lowers the barrier for entry, imitation, and then increases the difficulty in long-term competitive advantage. Under such circumstances, Teece et al. (1994) published the Dynamic Capabilities Theory, DCT, for the incomplete description of former competitive strategies such as Competitive Forces, Strategic Conflict, and Resource-Based Theory (RBT). DCT is referred to a firm¡¦s capabilities to integrate, build, and reconfigure internal and external competences to address rapidly changing environments. The purpose of this study is to apply the absorptive capabilities to investigate the affecting factors of organizations¡¦ dynamic capabilities from the knowledge management perspective. In addition, the path-dependence of absorptive capabilities is discussed and verified in this study as well. The empirical results show that absorptive capabilities have strong influence on organizations¡¦ dynamic capabilities and the path-dependence of absorptive capabilities is supported in this study. From the academic application, the results of this study provide the research model of absorptive capabilities and dynamic capabilities to the following researchers who are interested in these topics. And, from the practice implication, firms can adopt this results and suggestion of this study to build dynamic capabilities throuth knowledge absorption.

The research deals with the extent to which multi-national corporation rely on Taiwan subsidiaries¡¦ knowledge resource while operating their capital in subsidiaries in Mainland China. From the interview of the case study, there are three major driving forces affecting parent companies to count on their Taiwan subsidiaries, forces such as specific of parent companies, resource specific of Taiwan subsidiaries and local resource specific in Mainland China, Regarding specific of parent companies, the following factors effect the extent to which parent companies depend on Taiwan subsidiaries¡¦ knowledge resource:1.entry mode 2.experience in Chinese markets 3.The scope of value activities 4. the human resource exercise. Regarding resource specific of Taiwan subsidiaries, the following factors effect the extent to which parent companies depend on Taiwan subsidiaries¡¦ knowledge and resource.1.the strategic roles 2.strive actively to develop 3.industries 4. vertical and horizontal mode of value activities Regarding specific of local resource qualities in Mainland China, the following factors increase the extent to which parent companies depend on Taiwan subsidiaries¡¦ knowledge and resource.1.culture distance 2.uncertainty of local political and economic environment 3.industry value system of the local environment 4.local appropriate talent and the cost

Abstract Taiwan Tobacco and Wine Board Logistics Division¡¦s response strategies to Taiwan¡¦s entry into the World Trade Organization -from an integrated view of resource-base, resource-dependence, and network theories. The three theories including resource-base, resource-dependence, and network stress how companies obtain competitive advantage from inside to outside of the company. The synergy coming from integrating all three theories should further strengthen a corporation¡¦s competitiveness. After Taiwan¡¦s entry into the World Trade Organization, the tobacco and wine industry in Taiwan have faced fierce competition from new competitors. This poses both as a threat and as an opportunity for Taiwan Tobacco and Wine Board¡¦s Logistics Division. Through the analysis of the aforementioned three theories, this paper hopes to gain insight into how much competitive edge the Board has in terms of its advantages and disadvantages, its interdependence and relationship within the tobacco and wine industry as well as with other industries. Thus this paper hopes to combine and integrate the Division¡¦s external and internal resources and then make response strategies and policy suggestions accordingly. The results of this research include: 1. Products, price, distribution and sales channels, assets, and the competence of Taiwan Tobacco and Wine Board Logistics Division were all greatly affected by Taiwan¡¦s entry into the WTO. 2. Both assets and competences are considered as the company¡¦s internal resources. Advantages should be further made use of where disadvantages should be taken care of. 3. The Board¡¦s Logistics Division is currently most closely related to the tobacco and brewage factories under the same company. However, this relationship will be looser in the future due to the competition and the struggle to survive both entities face. On the other hand, the Logistics Division¡¦s relationship with transport companies, retailers, hypermarkets, convenience stores will be closer through investment, franchise, or partnerships. Its relationship with private sector manufacturers, domestic and oversea agents, cross-industry suppliers, distributors will also become much closer. 4. The Board¡¦s dependence on factories under the same company will decrease from highly dependent to a much lower degree ; its dependence on private sector manufacturers and domestic and oversea agents (who imports products from overseas after entry into the WTO) will grow from nil to highly dependent (dependence on importers already importing products before entry into WTO will decrease from an already meager degree to much less); dependence on cross-industry suppliers and distributors will become higher from a previously low degree; dependence on transport companies, retailers, hypermarkets and convenience stores will also become much higher from an already close relationship. 5. The Logistics Division should, after Taiwan¡¦s entry into the WTO, start from developing its internal advantages and disadvantages and search for ways to establish external links, as well as reducing its dependence on external sources. The three essential elements including resource-base, resource-dependence, and networks should be integrated through complement of resources, natural production, and increased interdependence. This and together with other strategies including diversification, strategic alliances, cooperating within the industry and across industries both domestically and internationally, should all be taken into account in the drawing up of response strategies in order to create competitive advantage for the Division. In view of these findings, this paper proceeds to make the following recommendations: 1. Increase retailer margins and encourage a more diversified range of promotional tactics. 2. Develop high-value products and improve package design. 3. Leverage existing advantages in distribution and sales channels and engage in the agency, distribution, and diversification into non-tobacco and nonalcoholic products. 4. Cut down distribution and sales channels and strengthen direct sales channels. 5. Intensify logistics and distributional functions. 6. Strengthen employees¡¦ professional knowledge and competence and improve information systems. 7. Accelerate the expansion of overseas markets, especially mainland China. 8. Speed up the company¡¦s privatization process. Based on an integrated view of resource-base, resource-dependence, and network theories, this paper presents a brief overview of how Taiwan Tobacco and Wine Board¡¦s Logistics Division¡¦s relationships with other companies in the same industry as well as cross-industry alliances had been affected post Taiwan¡¦s WTO entry. In view of these changes that have taken place, this paper also proceeds to make a few suggestions with regard to how the Logistics Division could respond to the challenges it now faces.

Individual-level life-history strategies are the rails that guide population dynamics. Due to the difficulty of conducting long-term, individual-based studies, current management practices often focus on estimating and controlling demographic rates with little consideration for the individual-level responses that guide them. This approach cannot account for important factors such as age-specific responses to changes in population density or long-term impacts of conspecific density and resource limitation. As such, population-level approaches may fail to predict age structure or the rate of population growth. Recent studies of mammals and birds have shown that short-term changes in factors such as population density can have lasting impacts on vital rates of individuals. These results highlight the importance of long-term individual-based analyses in understanding population dynamics. However, very few researchers have thus far been able to isolate and study interacting effects of density and resources on life histories apart from processes such as predation, interspecific competition, and management of anthropogenic disturbance. The feral horses (Equus ferus caballus) of Sable Island, Nova Scotia, Canada, exist in a natural though simplified system without predation, human interference, or interspecific competition (they are the island’s only terrestrial mammal, numbering approximately 500 individuals). Here I determined the roles of local conspecific density and an interacting resource gradient in guiding the reproduction and survival of adult female Sable Island horses (2008–2012). I used body condition (estimates of subcutaneous fat) as an indication of resource allocation towards the often conflicting purposes of reproduction and maintenance. Reproduction was best predicted by body condition (reproducing females were in relatively poorer condition) but there was also evidence of density-dependence in reproductive success. Survival was predicted by and positively related to body condition. Survival was also predicted by an interaction between conspecific density and location on the island consistent with expectations of a known east-west resource gradient that occurs on Sable Island (in available water and forage). Greater variability in fitness estimates in resource-poor, eastern Sable Island suggests that regions of low density and resources may be high risk/high reward habitats. Such habitats may be disproportionately avoided by young animals and exploited by senescent animals. All feral horses are descended from domesticated animals and recent work has found evidence of artificially selected life-history traits in unmanaged populations of domestic mammals like cattle, sheep, and horses (e.g., reproducing even at high densities and earlier in life than expected). I therefore attempted to determine if effects of artificial selection existed in the Sable Island population by examining age-based contributions to population growth and the relationship between reproduction (foaling) and female mortality. Perhaps due to the population’s long history of low management (>250 years), I failed to find any strong evidence of artificially selected life-history traits in Sable Island horses. That is, life history trade-offs in survival and reproduction in Sable Island horses were more similar to wild species of large herbivores inhabiting natural environments, than other populations of feral ungulates. My research suggests a rarely documented but fascinating instance of reversal of artificial selection by natural selection for a domesticated species like the horse.

How do legislatures develop or institutionalize? Our knowledge about legislative development is mostly based on studies of the U.S. House of Representatives and U.S. state legislatures. However, we know next to nothing about legislative development in the emerging democracies of Latin America. Given the need to develop effective democratic institutions in that region, it is critical to understand how institutions change and how legislatures in particular develop. In this study, I develop a model of legislative development that complements rational choice and path dependent explanations of change. In particular, this model provides an answer to the question: how does a legislative organization change into a legislative institution?In particular, I hypothesize that legislative development varies depending on the extent to which electoral and constitutional reforms balance executive-legislative power asymmetries. To test this hypothesis, I compare legislative development in Nicaragua (1979-2005) and Costa Rica (1871-2005). Central to the process of legislative development are: (1) power asymmetries between presidents and assemblies, (2) the rules and organizations that are established to balance these asymmetries, (3) how rules and organizations affect the development of the legislatures from simple, subordinate organizations into complex and autonomous institutions, and (4) how the broader social, political, and economic environment contributes to legislative development.I find that political actors do not act or function within an historical or contextual vacuum, nor does history and context alone determine political choices and outcomes. Instead, political actors function within rational, institutional, and historical boundaries, so an approach that incorporates aspects of both rational choice and path dependent explanations is preferable to existing models of legislative change. Therefore, part of my contribution is (1) to clarify the conceptual confusion surrounding institutions, organizations, and rules, and reduce ambiguity relating to their incorrect use in current scholarship; (2) to conceptualize legislative development as a process - not an outcome - that unfolds in a causally related sequence; and (3) to develop a Bounded Rationality Model that complements rational choice with path dependent explanations of legislative development to explain how organizations become institutions.

This study investigated the effects of hemisphericity and field dependence on programming skills. Twenty-five undergraduate university students from two introductory Logo programming courses completed the study. Results suggested that hemisphericity is related to the complexity of program structure (tree depth). Supplementary analyses indicated a negative correlation between previous programming experience and the use of recursion. Implications for education and suggestions for further research are discussed, and specific implications regarding the teaching of Logo are given.
