Properties of periodic arrays of symmetric complementary structuresand their application to grid amplifiers

Deschamps' theorem for n-terminal complementary structures is reviewed. An extension to Deschamps' theorem for a class of three-terminal bounded structures with one axis of symmetry is presented. It is shown that, for these structures, a simple relationship between the impedances of the odd mode of the original structure and the admittances of the even mode of the complementary structure exists, and that these modes are orthogonal. Using this, a self-complementary grid amplifier is designed and the measured results are presented

Generalized Nonlinear Complementary Attitude Filter

This work describes a family of attitude estimators that are based on a generalization of Mahony's nonlinear complementary filter. This generalization reveals the close mathematical relationship between the nonlinear complementary filter and the more traditional multiplicative extended Kalman filter. In fact, the bias-free and constant gain multiplicative continuous-time extended Kalman filters may be interpreted as special cases of the generalized attitude estimator. The correspondence provides a rational means of choosing the gains for the nonlinear complementary filter and a proof of the near global asymptotic stability of special cases of the multiplicative extended Kalman filter

The effects of the social norm on cigarette consumption: evidence from Japan using panel data

Using Japan’s prefecture-level panel data from 1989-2001, this paper examines the influence of the social norm on a person’s smoking behavior when the complementary relationship between smoking and drinking is taken into account. The key findings through a dynamic panel model controlling for unobserved prefecture-specific fixed effects are as follows: (1) Influence from others is stronger when people live more closely and cohesively. A tightly knit society results in a reduction of smoking through smoking-related interaction. (2) Smoking and drinking have a complementary relationship: greater initial consumption of alcohol results in larger consumption of cigarettes. (3) The complementary relationship between smoking and dinking is attenuated if the cost of committing the annoying conduct (i.e., smoking) is high. Overall, this empirical study provides evidence that the psychological effect of the presence of surrounding people has a direct significant effect upon smoking behavior and, furthermore, that it attenuates the complementary relationship between smoking and drinking, thereby reducing cigarette consumption. These results indicate that not only formal rules but also tacitly formed informal norms are effective deterrents to smoking.Smoking behavior, Social norm

Trade through FDI: investing in services

The type of relationship between different modes of trading services internationally is of great interest, both for the academic literature and for liberalization policies under the GATS, because cross-border and commercial presence abroad might complement or substitute each other. This paper offers a consistent theoretical foundation for the application of the gravity model to services trade, using a composite demand model yielding testable hypothesis about that complementary or substitutive relationship and linking the results to market regulations as trade barriers. For the OECD countries over 1994-2004 a robust complementary effects in the short-run is found, reinforced in the long-run by an increased potential for cross-border imports bases on pervious FDI inflows, highlighting business, communication and financial services.Imports, services, panel data, substitution and complementary effects

Tree-structured complementary filter banks using all-pass sections

Tree-structured complementary filter banks are developed with transfer functions that are simultaneously all-pass complementary and power complementary. Using a formulation based on unitary transforms and all-pass functions, we obtain analysis and synthesis filter banks which are related through a transposition operation, such that the cascade of analysis and synthesis filter banks achieves an all-pass function. The simplest structure is obtained using a Hadamard transform, which is shown to correspond to a binary tree structure. Tree structures can be generated for a variety of other unitary transforms as well. In addition, given a tree-structured filter bank where the number of bands is a power of two, simple methods are developed to generate complementary filter banks with an arbitrary number of channels, which retain the transpose relationship between analysis and synthesis banks, and allow for any combination of bandwidths. The structural properties of the filter banks are illustrated with design examples, and multirate applications are outlined

Complementary stereotyping of ethnic minorities predicts system justification in Poland

We investigate the phenomenon of complementary stereotyping of ethnic minorities in Poland and its relationship to system justification. Using results from a nationally representative survey we test the hypothesis that complementary stereotypes—according to which ethnic minorities are seen as possessing distinctive, offsetting strengths and weaknesses—would be associated with system justification among Polish majority citizens. For four minorities, results indicated that stereotyping them as (a) low in morality but high in competence or (b) high in morality but low in competence predicted greater system justification. These results suggest that even in a context that is low in support for the status quo, complementary stereotyping of ethnic minorities is linked to system justification processes. For the three minority groups that were lowest in social status, complementary stereotyping was unrelated to system justification. It appears that negative attitude towards these groups can be expressed openly, regardless of one’s degree of system justification

Absorptive capacity and relationship learning mechanisms as complementary drivers of green innovation performance

This paper aims to explore in depth how internal and external knowledge-based drivers actually affect the firms\u2019 green innovation performance. Subsequently, this study analyzes the relationships between absorptive capacity (internal knowledge-based driver), relationship learning (external knowledge-based driver) and green innovation performance. This study relies on a sample of 112 firms belonging to the Spanish automotive components manufacturing sector (ACMS) and uses partial least squares path modeling to test the hypotheses proposed. The empirical results show that both absorptive capacity and relationship learning exert a significant positive effect on the dependent variable and that relationship learning moderates the link between absorptive capacity and green innovation performance. This paper presents some limitations with respect to the particular sector (i.e. the ACMS) and geographical context (Spain). For this reason, researchers must be thoughtful while generalizing these results to distinct scenarios. Managers should devote more time and resources to reinforce their absorptive capacity as an important strategic tool to generate new knowledge and hence foster green innovation performance in manufacturing industries. The paper shows the importance of encouraging decision-makers to cultivate and rely on relationship learning mechanisms with their main stakeholders and to acquire the necessary information and knowledge that might be valuable in the maturity of green innovations. This study proposes that relationship learning plays a moderating role in the relationship between absorptive capacity and green innovation performance

Arguments in a Sartorial Mode, or the Asymmetries of History and Philosophy of Science

History of science and philosophy of science are not perfectly complementary disciplines. Several important asymmetries govern their relationship. These asymmetries, concerning levels of analysis, evidence, theories, writing, and training show that to be a decent philosopher of science is more difficult than being a decent historian. But to be a good historian-well, the degree of difficulty is reversed

Does Foreign Aid Increase Foreign Direct Investment?

The notion that foreign aid and foreign direct investment (FDI) are complementary sources of capital is conventional among governments and internationalcooperation agencies. This paper argues that the notion is incomplete. Within the framework of an open economy Solow model we show that the theoretical relationship between foreign aid and FDI is indeterminate. Aid may raise the marginal productivity of capital by financing complementary inputs, such as public infrastructure projects and human capital investment. However, aid may also crowd out productive private investments if it comes in the shape of physical capital transfers. We therefore turn to an empirical analysis of the relationship between FDI and disaggregated aid flows. Our results strongly support the hypotheses that aid invested in complementary inputs draws in foreign capital while aid invested in physical capital crowds out FDI. The combined effect of these two types of aid is small but on average positive.foreign aid; foreign direct investment (FDI); open economy Solow model
