Frames We Can Believe In: Official Framing and Ideology in the CCP’s Quest for Legitimacy

In the debate on authoritarian resilience, the importance of persuasion to regime legitimacy has been widely acknowledged, yet a conceptual framework explaining the role of persuasion is still lacking. Against this backdrop, we argue that the framing perspective (Benford and Snow 2000) provides a useful basis for such a framework. Drawing on Beetham’s (1991) model of legitimacy, we contend that the ruling elites in authoritarian regimes propagate official frames in a continuous effort to reproduce the belief of the populace in the elites’ leadership qualities and their determination to serve the common interest. In the empirical part of our paper we look at the case of China, where the Chinese Communist Party (CCP) has in recent years reemphasized persuasion as a means of reproducing legitimacy. We then apply our theory in an analysis of the conceptual shifts in the CCP’s frames and ideology, as propagated under its secretary general, Hu Jintao.China, authoritarianism , legitimacy, ideology

Query processing of geometric objects with free form boundarie sin spatial databases

The increasing demand for the use of database systems as an integrating factor in CAD/CAM applications has necessitated the development of database systems with appropriate modelling and retrieval capabilities. One essential problem is the treatment of geometric data which has led to the development of spatial databases. Unfortunately, most proposals only deal with simple geometric objects like multidimensional points and rectangles. On the other hand, there has been a rapid development in the field of representing geometric objects with free form curves or surfaces, initiated by engineering applications such as mechanical engineering, aviation or astronautics. Therefore, we propose a concept for the realization of spatial retrieval operations on geometric objects with free form boundaries, such as B-spline or Bezier curves, which can easily be integrated in a database management system. The key concept is the encapsulation of geometric operations in a so-called query processor. First, this enables the definition of an interface allowing the integration into the data model and the definition of the query language of a database system for complex objects. Second, the approach allows the use of an arbitrary representation of the geometric objects. After a short description of the query processor, we propose some representations for free form objects determined by B-spline or Bezier curves. The goal of efficient query processing in a database environment is achieved using a combination of decomposition techniques and spatial access methods. Finally, we present some experimental results indicating that the performance of decomposition techniques is clearly superior to traditional query processing strategies for geometric objects with free form boundaries

Propagation of two southern Texas shrubs by stem cuttings

We successfully used stem cuttings to propagate two native shrubs, brush holly (Xylosma flexuosa) and devil\u27s claw. (Pisonia aculeata), which are rare in the Rio Grande floodplain of southern Texas. Roots grew on 100 percent of the cuttings that did not receive root-promoting substances. Rooting success decreased when synthetic root promoting substances or a nutrient solution was used. Key words: asexual propagation; native shrubs

Enhanced TiO2 Photocatalytic Processing of Organic Wastes for Green Space Exploration

The effect of transition metal co-catalysts on the photocatalytic properties of TiO2 was investigated. Ruthenium (Ru), palladium, platinum, copper, silver, and gold, were loaded onto TiO2 powders (anatase and mixed-phase P25) and screened for the decomposition of rhodamine B (RhB) under broad-band irradiation. The morphology and estimated chemical composition of photocatalysts were determined by scanning electron microscopy and energy dispersive spectroscopy, respectively. Brunhauer, Emmett and Teller (BET) analysis measured mass-specific surface area(s). X-ray diffraction analysis was performed to confirm the identity of titania phase(s) present. The BET surface area of anatase TiO2/Ru 1% (9.2 sq m/gm) was one of the highest measured of all photocatalysts prepared in our laboratory. Photolyses conducted under air-saturated and nitrogen-saturated conditions revealed photodegradation efficiencies of 85 and 2 percent, respectively, after 60 min compared to 58 percent with no catalyst. The cause of low photocatalytic activity under an inert atmosphere is discussed. TiO2/Ru 1% showed a superior photocatalytic activity relative to P25-TiO2 under broad-band irradiation. A potential deployment of photocatalytic technologies on a mission could be a reactor with modest enhancement in solar intensity brought about by a trough-style reactor, with reactants and catalyst flowing along the axis of the trough and therefore being illuminated for a controlled duration based on the flow rate
