The paper introduces the highly problematic nature of modelling in design and technology education and examines the relationship
between cognitive and concrete modelling. Its aim is to gain insight into what learners do, rather than what others say they
ought to do in their learning activities. The variety of purposes that educators have for learners’ modelling are discussed
through examining the contested curriculum justification for design and technology education itself. The paper proposes that
learners’ modelling cannot be extracted from the social milieu in which they act and it provides some insights of these social
influences through the analysis of two case studies. Their settings are a girls’ secondary school and a college of higher
education. Each case study is presented independently but organised with a common format to consider a) the impact of assessment
on learning intentions and outcomes; b) cultural influences on learning and modelling; c) social influences on learning and
modelling. A discussion of the emergent themes considers implications for teachers.

This paper examines the 205 insolvent thrifts that were resolved in 1988 and assesses the cost savings obtained by selling
179 of the institutions through assisted acquisitions rather than liquidating them. It is hypothesized that the cost savings
were determined by factors related both to the future viability of the acquired institution and the particulars of the deal
arranged by the Federal Home Loan Bank Board and the Federal Savings and Loan Insurance Corporation. The added value by selling
a thrift is determined primarily by the level of core deposits obtained by the acquired thrift. However, the branch structure
and purchased mortgage-servicing rights should also add franchise value to the firm. In addition to these factors, the analysis
accounts for the tax benefits and other regulator forbearances associated with the deals. Other characteristics of the deals
are also considered. It is found that core deposits, tax benefits, purchased mortgage-servicing rights, average branch size,
and type of acquirer, as well as some other factors, were significant determinants of the cost savings obtained through selling
an institution rather than liquidating it. 相似文献

Time--there is never enough of it. There are never enough hours in the day to do everything at work and at home. Today's employees, forced to choose between work obligations and family responsibilities, often feel frazzled and guilty. Some employers recognize these conflicts and are finding ways to lighten the work/family load. They are offering a sophisticated combination of dependent-care options, flexible work hours and family-related benefits tailored to meet the needs of the employees within their specific industries. HRMagazine looks at leaders in six major industries--manufacturing, health, communications/technology, financial management, government and retail. No one can give employees that 25-hour day that everyone feels they need to juggle all their work and family obligations. But these industry leaders have provided a nurturing environment where employees can successfully balance those obligations. 相似文献

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification. 相似文献

Uncertainty and Financing Constraints 总被引:5,自引:0,他引:5
Using a panel of Dutch listed firms this paper provides empirical evidence for the hypothesis that more risky firms are confronted with more severe capital market constraints than relatively less risky firms. The paper also contributes to the discussion on the usefulness of cash flow as a measure of financial constraints. We present a stochastic version of the Kaplan-Zingales (1997) model. We show that cash flow sensitivity can be used as a meaningful indicator of financing constraints if firms are classified by the degree of uncertainty they face and if the uncertainty originates from cost uncertainty. 相似文献

This paper discusses the literature on delisting, drawing on USA and international evidence. Given the great heterogeneity in delisting operations, we first consider the standard existing typology based on the initiator of the delisting (the stock market authorities, or the firm itself). Second, while managers often cite high compliance costs (especially due to Sarbanes–Oxley Act implementation) as the official reason for the voluntary delisting of their firm, we highlight that firms face different trade-offs in their delisting decision. We also examine the reasons for involuntary delisting, especially the delisting dilemma faced by stock market authorities when the firm violates the listing requirements. Next, we review the economic consequences of delisting in terms of value creation or value destruction for shareholders. Finally, noting gaps in the literature and other contrasting results, we propose suggestions for future research. 相似文献

This article investigates the relationship between fees for audit and non-audit services with Tobin's Q. Using a sample of Brazilian public companies in the period from 2009 to 2011, we estimate the association between Tobin's Q and the auditors' remuneration scaled by total assets. Additionally, to strengthen the conclusions, we present a second model with the remuneration of the auditors in absolute terms. The results suggest a significant relationship between Tobin's Q and audit and non-audit fees, positive and negative, respectively. Specifically, increases in audit fees and non-audit fees respectively increase and decrease the Tobin's Q of the audited company. The results of this study have important implications for those interested in good corporate governance practices. Managers and board members concerned with value carefully evaluate the remuneration and nature of services creation, when engaging independent auditors, should provided. 相似文献
