Expenditure System

This paper innovatively constructs a panel extended linear expenditure system (ELES) model including the theory of internal and external habit formation and analyzes the time effect of consumption habits and the regional differences of the comparison effects on rural residents in a variety of consumption expenditures from a temporal and spatial perspective. This research demonstrates the following. Firstly, overall, rural residents have least internal habits in terms of subsistence spending, followed by developmental spending and the most in enjoyment spending. Secondly, China’s rural residents consider the “actual use value” of commodities in “introverted” consumption expenditures; but in “export-oriented” consumption expenditures, besides the “actual use value” of the goods, they also seek to fulfill their “emotional demands”. Thirdly, there is the largest comparison effect on food and housing consumption expenditures for rural residents in coastal economic developed regions, and the smallest comparison effect on clothing, transportation, cultural and educational expenditures. It is the largest comparison effect on clothing and medical care expenditures for rural residents in underdeveloped regions of the central and western, and the smallest comparison effect on food and housing consumption expenditures.

Over Time

Compared to income or wealth, household consumption expenditures can reveal households’ real economic well-being derived from income and other material resources. This chapter uses the CHIP data from 1995, 2002, and 2013 to investigate the structure and inequality of consumption expenditures in urban China. Overall inequality in urban household consumption expenditures as measured by the Gini coefficient decreased slightly from 1995 to 2002 but then increased to 2013. The percentile ratio of p90/p10, however, increased continuously during these years. Basic food consumption inequality was much smaller than inequality of overall consumption, and as consumption grew over time, the food share of consumption fell steadily—from 34 percent in 1995 to 24 percent in 2013. Housing consumption inequality was much larger than overall consumption inequality but it decreased over time. Housing’s share of total consumption, however, rose markedly from 23 percent in 1995 to 38 percent in 2013.

SummaryEquivalence scales are a prerequisite for any economic well-being comparison with measures on income distribution, inequality and poverty. This paper provides new equivalence scales based on revealed preference consumption microdata. We concentrate on single expenditure Engel equations and on a complete demand system, the extended linear expenditure system (ELES), with all interdependencies of a full market basket.Microdata base is the newest availabe West German Income and Consumption Sample of 1983 with more than 42,000 households. Our results with differences regarding the goods' basket and household composition effects are compared to other discussed consumption, expert, and subjective based equivalence scales.

Actual Use

This article deals with the age-old problem of the literary canon, from a perspective that tries to supersede the still dominating questions of nation building or mainstream versus minorities culture. Taking stock from the observation that recent debates have moved the question to the field of the creative industries as well as that of cultural policy, it asks instead questions on the actual use and use-value of the canon, which is here reframed from the point of view of both writers and policy makers.

AbstractUsing a new ID hybrid model of the electron bombardment in flare loops, we study not only the evolution of densities, plasma velocities and temperatures in the loop, but also the temporal and spatial evolution of hard X-ray emission. In the present paper a continuous bombardment by electrons isotropically accelerated at the top of flare loop with a power-law injection distribution function is considered. The computations include the effects of the return-current that reduces significantly the depth of the chromospheric layer which is evaporated. The present modelling is made with superthermal electron parameters corresponding to the classical resistivity regime for an input energy flux of superthermal electrons of 109erg cm−2s−1. It was found that due to the electron bombardment the two chromospheric evaporation waves are generated at both feet of the loop and they propagate up to the top, where they collide and cause temporary density and hard X-ray enhancements.

Cell Surface Glycoconjugates

Cell surface glycoconjugates are considered to play important roles in cell-cell interactions in the developing central nervous system. We have previously described a group of monoclonal antibodies that recognize defined carbohydrate epitopes and reveal unique temporal and spatial patterns of immunoreactivity in the developing main and accessory olfactory systems in rats. Antibody CC2 reacts with complex α-galactosyl and α-fucosyl glycoproteins and glycolipids. Antibody CC1 reacts with terminal N-acetyl galactosamine residues of globoside-like glycolipids. Antibody 1B2 reacts with β-galactosyl glycolipids and glycoproteins. Our light microscopic data suggest that these antigens may be located on the surfaces of axons of the vomeronasal and olfactory nerves as well as on some of their target neurons in the main and accessory olfactory bulbs.

Although confronting cistemae (CC) have been observed in a variety of tumor cells and normal fetal rat, mouse, and human epithelial tissues, little is known about their origin or role in mitotic cells. While several investigators have suggested that CC arise from nuclear envelope (NE) folding back on itself during prophase, others have suggested that CC arise when fragments of NE pair with endoplasmic reticulum. An electron microscopic investigation of 0.25 um thick serial sections was undertaken to examine the origin of CC in HeLa cells.

Measurement of the egg's electrical activity, the fertilization potential or the activation current (in voltage clamped eggs), provides a means of detecting the earliest perceivable response of the egg to the fertilizing sperm. By using the electrical physiological record as a “real time” indicator of the instant of electrical continuity between the gametes, eggs can be inseminated with sperm at lower, more physiological densities, thereby assuring that only one sperm interacts with the egg. Integrating techniques of intracellular electrophysiological recording, video-imaging, and electron microscopy, we are able to identify the fertilizing sperm precisely and correlate the status of gamete organelles with the first indication (fertilization potential/activation current) of the egg's response to the attached sperm. Hence, this integrated system provides improved temporal and spatial resolution of morphological changes at the site of gamete interaction, under a variety of experimental conditions. Using these integrated techniques, we have investigated when sperm-egg plasma membrane fusion occurs in sea urchins with respect to the onset of the egg's change in electrical activity.

Kinetochore Function

Abstract Kinetochores are instrumental for accurate chromosome segregation by binding to microtubules in order to move chromosomes and by delaying anaphase onset through the spindle assembly checkpoint (SAC). Dynamic phosphorylation of kinetochore components is key to control these activities and is tightly regulated by temporal and spatial recruitment of kinases and phosphoprotein phosphatases (PPPs). Here we focus on PP1, PP2A-B56 and PP2A-B55, three PPPs that are important regulators of mitosis. Despite the fact that these PPPs share a very similar active site, they target unique ser/thr phosphorylation sites to control kinetochore function. Specificity is in part achieved by PPPs binding to short linear motifs (SLiMs) that guide their substrate specificity. SLiMs bind to conserved pockets on PPPs and are degenerate in nature, giving rise to a range of binding affinities. These SLiMs control the assembly of numerous substrate specifying complexes and their position and binding strength allow PPPs to target specific phosphorylation sites. In addition, the activity of PPPs is regulated by mitotic kinases and inhibitors, either directly at the activity level or through affecting PPP–SLiM interactions. Here, we discuss recent progress in understanding the regulation of PPP specificity and activity and how this controls kinetochore biology.
