Development of a Novel Low-Silver Cu-P Brazing Filler Metal Bearing Sn

The flame brazing of H62 brass using a novel, low-silver Cu-P brazing filler metal was investigated in this study. The effect of the addition of a trace amount of Sn on the microstructure and properties of Cu-7P-1Ag filler metals was analyzed by means of X-ray diffractometer, scanning electron microscopy and energy dispersive spectrometer. The addition of trace Sn led to a decrease in the solidus and liquidus temperatures of Cu-7P-1Ag filler metals. Meanwhile, the spreading performance of the filler metals on a H62 brass substrate was improved. The microstructure of the low-silver, Cu-P brazing filler metal was mainly composed of α-Ag solid solution, α-Cu solid solution and Cu3P; an increase of Sn content led to the transformation of the microstructure of the joints from a block to a lamellar structure. When the Sn content was 0.5 wt. %, the shear strength of the joint at room temperature reached 348 MPa, and the fracture morphologies changed from a cleavage to a quasi-cleavage structure.

CLEAVAGE STRUCTURE CHANGE IN THE 2019 GENERAL ELECTION IN INDONESIA

This paper examines the following puzzle in the Indonesian electoral results: while the 2019 election showed clear cleavage voting at the presidential level, such voting was not apparent in the national legislative elections, which are held at the same time. It considers two different explanations for this divergence, split-ticket voting and the distinctions in the electoral system between the presidential election and the election for the national legislature. It concludes that the structure of the different voting systems does the best job of explaining the differences in voting patterns.

Cleavages and Government in Slovenia and Montenegro

In this article we identify the factors that contribute to the formation and especially the durability/stability of governments in both Slovenia and Montenegro after they formally introduced multiparty systems and following their democratic transition, with a focus on the effect of cleavages and party system characteristics generally. Although these two polities share several important similarities (small size, common institutional setting during Yugoslav era, aspirations for membership in international organisations etc.), the nature of governments’ durability/stability in the democratic era entails distinct differences. While Montenegro stands out in post-socialist Europe as the only case where the ruling party has not been overthrown, Slovenia has been led by many governments composed of different political parties. While it seems that in neither country are the ideological characteristics of the governments able to explain their duration/stability to any important extent, it is obvious that the cleavage structure in the two countries has varied, as has the importance of particular cleavages.

Party System Linkage

This chapter examines two forms of integrated politics at the party system level, party system congruence and party system nationalization. Drawing on data from over 2,220 subnational elections in seven multi-level systems, it assesses three forms of party system congruence across the units of a multi-level system: similarity of the number of parties, electoral support, and similarity of the magnitude and direction of the electoral swing. Using the index of cumulative regional inequality (CRI), it measures the territorial concentration of party systems. The analysis shows that fiscal centralization and administrative interdependence predict integrated politics in the form of more congruent patterns of electoral support. There are limits to the institutional explanation. The electoral system and social cleavage structure are important explanations of variation in party system structures and territorial concentration.

The Spatial Articulation of Urban Political Cleavages

Synthesizing and extending multiple literatures, this article develops a new approach for exploring the spatial articulation of urban political cleavages. We pursue three questions: (1) To what extent does electoral conflict materialize between rather than within neighborhoods? (2) How salient are group, place, and location in defining urban cleavages? (3) How do these sources inflect one another? To answer these questions, the article analyzes a novel longitudinal database of neighborhood-scale mayoral voting in Chicago, Toronto, and London. We find strong evidence of spatially articulated cleavages: in each city, voting patterns are equally or more geographically concentrated than the non-White population, income, and poverty. While group-based interests define Chicago’s cleavage structure, place and location are paramount in Toronto and London. We conclude by proposing a research agenda for investigating the spatiality of urban politics and advancing a preliminary typology of urban political cleavages and the conditions under which they may arise.

Cleavage structure and the demise of a dominant party: The role of national identity in the fall of the KMT in Taiwan

The KMT’s electoral defeat in 2016 was not a case of a dominant party crashing to defeat due to mismanaging its factions or ineptly allocating state resources. This article illustrates a third path by which dominant parties can lose power. The KMT lost because the underlying cleavage structure slowly shifted and eroded the KMT’s political foundations over a quarter century. Indeed, the KMT had ceased to be a dominant party long before 2016; that election was merely a particularly dramatic step in what was actually a long decline. Taiwan has a single dominant political cleavage defined by national identity. Since the early 1990s, exclusive Taiwanese identity has gradually increased and eventually replaced both Taiwanese and Chinese identity as the majority disposition. As the cleavage line gradually shifted, the KMT tried to develop other appeals, but these were only successful as long as they did not directly clash with the dominant national identity cleavage.
