服务质量要素体系的探讨

The study explored consumers' evaluation factor system and the zone of tolerance in the service quality, and the impact on consumer behavior in two branches of trade: the shopping center and the architectural material corporation, with the method of questionnaire survey. The main conclusions are as following: 1) The basic factors on service quality of shopping center are five, such as assurance、tangibles、the services of the post-selling、convenience and reliability. 2) There are also five factors on service quality of the architectural material corporation, such as the supplying of the products, the abilities of the salesmen, courtesy, package and the information. 3) The zones of tolerance of the factors in service quality are difference. In some way, they reflect the importance of the factors. 4) the service quality and its factors have positive impacts on the consumer behaviors. 5) In the branch of glass producing in our country, the service quality of a corporation is significant below the ideal level, even if it is a good one which the consumers expressed positive purchase intention on the corporate. The service quality of the coporate on which the consumers expressed uncertain purchase intention, is in nearby of the minimum acceptable level.

上市公司经营管理者绩效－报酬与激励机制初探

This research aims at the CEO's (chief executive officer) incentive-reward system and investigates 456 companies that have come into the market. The structure and level of agent reward are analyzed. And the problem in the incentive-reward mechanism is brought forward. The agent's payments are poor comparing to their contributions. And stock is not a primary incentive. Bonus compensation is still the dominant incentive means. By questionnaire and interview, it was fond that matriel need was rank first among these CEOs'needs. These foundinds indicate that the agents' payment is too poor to work as an effective incentive. The corporation's agent incentive is not enough in fact. The two reasons about this problem lie in our institutions and traditional opinions about commerce. To solve this matter, we must establish a scientific and reasonable evaluation system and incentive-reward system. At the same time, the market system and corporation management mechanism are absolutely need.

品牌形象的消费行为学分析

Brand image is the attributes set and the related associations of a brand in consumers mind, and it is the subjective reflections of brands. The paper explored the factors of brand image system and their weight. As the traditional means to evaluate weight coefficients are not perfect, a new method, conjoint analysis, was attempted. The factors of brand image were explored through questionnaire. Sports sneaker, toothpaste, and personal stereo were chosen as product sample, and four hundred and twenty university students from Tangshan city and Beijing as subjects(each person evaluated two kinds of products). The first two kinds of products were requisites of students, and sports sneaker belonged to High conspicuous products and toothpaste was low conspicuous product. On the other hand, personal stereo was the sample of development and entertainment products. Several factors of three products brand were taken out with factor analysis. In order to explore the weight of the brand image factors, a contrast of factor contribution ratio method, holistic quartation method and conjoint analysis is made here. Twenty university students evaluated the weight of the image factors of three kinds of brand with holistic quartation method, then they gave the weight of personal stereo with conjoint analysis method. Product function, advertising and propaganda, symbolic meaning, market orientation, brand appetency, consuming experience are the factors of sports sneaker brand image. Product function, advertising and propaganda, market orientation, product grade, corporation image are the factors of toothpaste brand image. Corporation image and product function, advertising and propaganda, consuming experience, symbolic meaning, price and function ratio are the factors of personal stereo brand image. So the hypothesis was proved that brand image is an ordinal and organical system, "ordinal" means the weight of factors are different, "organical" means that brand image can be deposed into several factors and the factors belonged to function components and meaning components (function components are the factors about physical characteristics and function, which are called "hard factors"); meaning factors are those that can show the personality、value and lifestyle of consumers, which are called "soft factors". The research also gave evidence of the hypothesis below: the factor structures of brand image of different product category have commonness and individuality; the function components of low conspicuous products are more important than the high conspicuous products. The exploration of conjoint analysis is what the paper seeks to be some creative in some degree.

Identification, Selection, and Enrichment of Cardiomyocyte Precursors

The large-scale production of cardiomyocytes is a key step in the development of cell therapy and tissue engineering to treat cardiovascular diseases, particularly those caused by ischemia. the main objective of this study was to establish a procedure for the efficient production of cardiomyocytes by reprogramming mesenchymal stem cells from adipose tissue. First, lentiviral vectors expressing neoR and GFP under the control of promoters expressed specifically during cardiomyogenesis were constructed to monitor cell reprogramming into precardiomyocytes and to select cells for amplification and characterization. Cellular reprogramming was performed using 5'-azacytidine followed by electroporation with plasmid pOKS2a, which expressed Oct4, Sox2, and Klf4. Under these conditions, GFP expression began only after transfection with pOKS2a, and less than 0.015% of cells were GFP(+). These GFP(+) cells were selected for G418 resistance to find molecular markers of cardiomyocytes by RT-PCR and immunocytochemistry. Both genetic and protein markers of cardiomyocytes were present in the selected cells, with some variations among them. Cell doubling time did not change after selection. Together, these results indicate that enrichment with vectors expressing GFP and neoR under cardiomyocyte-specific promoters can produce large numbers of cardiomyocyte precursors (CMPs), which can then be differentiated terminally for cell therapy and tissue engineering.

Niezamknięte księgi – o księgach cechowych na Pomorzu Zachodnim

Niniejsze badanie koncentruje się na księgach powstałych w wyniku działalności organizacji cechowych na Pomorzu Zachodnim. Jest to specyficzny rodzaj zabytków, w których odzwierciedla się życie zarówno zawodowe, jak i społeczne oraz towarzyskie korporacji. Pisane były niejednokrotnie przez kolejne pokolenia, obejmują nawet kilka stuleci, przez co stanowią cenne źródło historyczne. Księgi dzieliły się na urzędowe, obejmujące całokształt działalności (Amtsbuch), oraz wyspecjalizowane – księgi protokołów (Protokollbuch), księgi mistrzów, czeladników i uczniów (Meister-, Gesellen- i Lehrjungenbuch), księgi rachunkowe (Rechnungsbuch) i księgi normatywne. Tekst ukazuje znaczną różnorodność kwestii poruszanych w poszczególnych rodzajach ksiąg, a także ich formę zewnętrzną. Podstawę do badań stanowią obiekty przechowywane w Archiwum Państwowym w Szczecinie. Daleko posunięte podobieństwo w funkcjonowaniu cechów poza granicami Pomorza pozwala na przeniesienie wniosków również na inne organizacje cechowe.

Stability of time-delay systems via Lyapunov functions

In this paper, a Lyapunov function candidate is introduced for multivariable systems with inner delays, without assuming a priori stability for the nondelayed subsystem. By using this Lyapunov function, a controller is deduced. Such a controller utilizes an input-output description of the original system, a circumstance that facilitates practical applications of the proposed approach.

An Independent-Connection Model for Traffic Matrices

A common assumption made in traffic matrix (TM) modeling and estimation is independence of a packet's network ingress and egress. We argue that in real IP networks, this assumption should not and does not hold. The fact that most traffic consists of two-way exchanges of packets means that traffic streams flowing in opposite directions at any point in the network are not independent. In this paper we propose a model for traffic matrices based on independence of connections rather than packets. We argue that the independent connection (IC) model is more intuitive, and has a more direct connection to underlying network phenomena than the gravity model. To validate the IC model, we show that it fits real data better than the gravity model and that it works well as a prior in the TM estimation problem. We study the model's parameters empirically and identify useful stability properties. This justifies the use of the simpler versions of the model for TM applications. To illustrate the utility of the model we focus on two such applications: synthetic TM generation and TM estimation. To the best of our knowledge this is the first traffic matrix model that incorporates properties of bidirectional traffic.

Neural Pattern Recognition on Multichannel Input Representation
