第四种电子商务形式的兴起

团购即为一个团队向商家采购,国际通称B2T(Business To Team),是继B2B,B2C,C2C后的第四种电子商务模式.团购 B2T,本来是"团体采购"的定义,而今,网络的普及让团购成为了很多中国人参与的消费革命.网络成为一种新的消费方式,所谓网络团购,就是互不认识的消费者,借助互联网的"同聚人的力量"来聚集资金,加大与商家的谈判能力,以求得最优的价格.     

超大跨径T梁张拉过程中的侧弯问题初探

50米T梁可以说是T梁经济跨度的极限,当跨径大于50米时,梁体自身重量大,在运输和吊装上面都存在一定的难度,所以使用上受到一定的限制。本文着重探讨50米T梁张拉时的侧弯问题。     

How Service-Related Factors Affect the Survival of B2T Providers: A Sentiment Analysis Approach

ABSTRACT

Nearly one-third of the business-to-team (B2T) websites in China closed down in 2011—the casualties of the intensified competition in the group-buying market. To investigate the critical factors to the survival of online B2T businesses in an overcrowded buyer-side market, we propose a model that links convenience, price, product/service, personalization, and website security/safety to customer satisfaction of B2T websites in light of the related literature. A two-stage approach is applied to validate this model. In Stage I, according to the results of an empirical analysis based on questionnaire responses from 157 B2T website users, we found that convenience and product/service are the top two contributors to the success of B2T business, as measured by customers’ repurchase intentions. In Stage II, topic classification and sentiment analysis are applied to 3046 review comments related to 58 B2T websites. The results from the Stage II study confirm the validity of the Stage I results with further evidence to support our arguments.     

Beyond the principle of population: Malthus's Essay

Abstract

After an introductory section, this article reviews reasons and arguments establishing the invalidity of Malthus's construct of a ‘principle of population’. Section 3 propounds that Malthus's theory is located beyond the principle of population, with the oscillation figure as its centre. Section 4 takes note of the trajectory which the Essay describes between natural and moral science, assesses inequality and growth as the two focal points of Malthus's theory and eventually observes Malthus looking forward to a state beyond the dictates of growth.     

On ridge estimators for the negative binomial regression model

The negative binomial (NB) regression model is very popular in applied research when analyzing count data. The commonly used maximum likelihood (ML) estimator is very sensitive to highly intercorrelated explanatory variables. Therefore, a NB ridge regression estimator (NBRR) is proposed as a robust option of estimating the parameters of the NB model in the presence of multicollinearity. To investigate the performance of the NBRR and the traditional ML approach the mean squared error (MSE) is calculated using Monte Carlo simulations. The simulated result indicated that some of the proposed NBRR methods should always be preferred to the ML method.     

Integrating accounting and statistics: Forecasting,budgeting and production planning at the American Telephone and Telegraph Company during the 1920s

Drawing on the scholarly perspectives of James R. Beniger and Alfred D. Chandler, we examine a long‐term process of firm‐specific learning at the American Telephone and Telegraph Company (AT&T). Extensive archival records reveal the firm's efforts to improve its informational resources for market planning, capital budgeting and production scheduling in the 1920s. These initiatives were meant to minimise the likelihood of a repetition of the financial crisis that nearly drove AT&T into bankruptcy in 1906–07. The informational innovation was costly as it required specialised human capital, the identification of suitable metrics corresponding to underlying business processes and the integration of these metrics within the elements of a complex firm. Such a transformation developed more reliable forecasting of future demand for telecommunication services. Central to this process was the adaptation of new econometric methodologies for predicting business cycle fluctuations and the integration of these findings into operational plans. Reforms of this sort helped to quantify risk and reduce internal asymmetries that threatened to undermine the smooth, integrative management of AT&T's corporate headquarters unit, its regional operating subsidiaries and Western Electric, its captive manufacturing arm. Our study contributes to a deeper understanding of the historical evolution of management accounting by studying firm‐specific learning to combat external uncertainties and internal information asymmetries in the coordination and control of a giant business enterprise.     

对我国T＋1交易制度下IPO抑价和高换手问题的探析

文章从我国特殊的交易制度T＋1的特点出发,分析了在该交易制度下,我国IPO股票的不正常高抑价和高换手率。T＋1的特点是：首日只能是中签者卖出,且涨跌无限制,而买者当日无论股价涨跌多大,都不能卖出。因此,按常理IPO股票不应该出现高抑价和高换手率,但我国的IPO股票却出现了。这种制度造成了IPO股票出现高抑价和高换手率,建议管理层应加强对现行交易制度下,不正常的新股首日高抑价和高换手的监管,防范动机不良的交易者的违法乱市行为。
