This paper investigates how multiple and competing objectives are managed within an organisation, and the role that the Balanced Scorecard (BSC) plays in balancing organisational objectives. The issue of achieving multiple objectives, those which represent the interests of various stakeholders, has come to the forefront of the corporate agenda, as companies are seen increasingly as more than a source of profit for shareholders, but rather as ‘citizens’ playing a broader role in society. This study adopts an exploratory case study approach to understand how the BSC is used in management decision and control processes to assist with the balancing of objectives. The case organisation is a state-owned electricity company, and provides a unique setting where multiple and equally important strategic objectives exist. The results demonstrate that the BSC has the potential to help in making trade-offs and balancing objectives, but there are certain requirements for this to succeed. The paper provides insights into issues of balanced strategic management, as it discusses ‘balance’ in terms of both process and outcomes. 相似文献

The mixture of type-I and type-II censoring schemes, called the hybrid censoring scheme is quite common in life-testing or
reliability experiments. In this paper, we consider the competing risks model in presence of hybrid censored data. Under this
set up, it is assumed that the item may fail due to various causes and the corresponding lifetime distributions are independent
and exponentially distributed with different scale parameters. We obtain the maximum likelihood estimators of the mean life
of the different causes and derive their exact distributions. Using the exact distributions, all the moments can be obtained.
Asymptotic confidence intervals and two bootstrap confidence intervals are also proposed. Bayes estimates and credible intervals
of the unknown parameters are obtained under the assumptions of independent inverted gamma priors of the mean life of the
different causes. Different methods have been compared using Monte Carlo simulations. Onereal data set has been analyzed for
illustrative purposes.

Sets of incomplete and completed spells of unemployment wereobtained from the Italian Quarterly Labour Force Survey,carried out by ISTAT in Emilia-Romagna (1993:1–1995:1).The data were analysed through a proportional hazards modelwith a Weibull specification of the baseline hazard, includingboth unobserved heterogeneity applied to the scale parameterof the duration distribution, and telescoping effect to accountfor spikes in the distribution of unemployment spells.They were compared formally also with a non-proportional hazardmodel based on a log-logistic distribution of duration.The estimation of the parameters was carried out separately on bothcompleted spells and quarterly incomplete spells to ascertaindifferences and to envisage the potential seasonal effect.The results showed that the shape parameters changed over time.The parameters of each covariate proved to be statisticallystable over time and were also equal to the parameters ofthe completed spells model.Therefore, the analysis of incomplete spells is fairly feasiblewhen an even (closed form) baseline hazard function is suitablefor data. 相似文献

In this paper we examine a multiplicative intensity model in which a covariate interacts with two other covariates in the same model. We demonstrate, analytically, that in such situations a log-linear parameterization based on two pairs of baseline levels cannot be transformed, uniquely, to the, otherwise equivalent, multiplicative parameterization. We show that the problem lies in an oversight of the conditional independence between the two covariates interacting with a common third covariate. As a solution, therefore, we propose an approach that takes due account of such dependence. Our proposed approach uses a common baseline level for the three covariates involved in interaction while estimating the corresponding relative intensities. The issues addressed are illustrated with a demographic data set involving the estimation of rates of transition to parenthood. 相似文献

根据会计与预算的关系,可将政府会计区分为模式X和模式Y。模式X认为会计附属于预算,强调政府内部的受托责任;模式Y认为会计对预算施加重大影响,强调政府整体对公民的受托责任。根据会计环境和实际情况,目前我国政府会计只能选择模式X。鉴于预算执行与预算控制的重要性,我国在制定政府会计准则时,需要兼顾预算执行和控制方面的要求,并在政府预算和政府会计之间进行协调。 相似文献

This article sets out to investigate to what extent conventional retrospective measurement of family background leads to biases in the effects of family background in status attainment research. Multiple informant models show that the effect of father’s educational attainment on respondent’s educational attainment is 41% greater than conventional research suggests, and that the effect of father’s occupational status on respondent’s educational attainment becomes zero. The direct effect of respondent’s educational attainment on respondent’s occupational status is 21% greater after the unreliability in the respondent’s answers has been taken into account. We conclude that measurement error seriously biases conclusions about the status attainment process in the Netherlands. 相似文献

Nonlinear relationships in structural equation analysis became moreinteresting for applied researchers since the implementation of nonlinearconstraints in software programs (i.e., LISREL). This article provides acomprehensive application of the expectancy × value part of the Theory of Planned Behavior (Ajzen, 1991) including interactions of latent variables.The main purpose of the study is to overcome limitations of similarprevious analyses of Baumgartner and Bagozzi (1995) and Yang Jonsson (1997,1998) with an empirical example from representative survey data. Nonlinearrelationships of the theories' constructs (Attitude toward the behavior, subjectivenorm and perceived behavioral control) are analyzed one upon another withmultiple group comparisons and latent interaction models. Results confirmthe strategy to use multiple group techniques for preliminary analyses(i.e., detection of an interaction effect). With latent interaction models thestrength and the significance of the interaction is estimated under controlfor random measurement error. Parameters, standard errors, andgoodness-of-fit statistics are compared between three estimationtechniques (ML, GLS and WLS). Multiple group analyses and latentinteraction modeling detect a significant interaction for perceivedbehavioral control but not for attitude toward the behavior and subjective norm. Variations of the estimators of the perceived behavioral controlsubmodel is proved by bootstrapping. Further model improvements andalternative model techniques are discussed in the final chapter. 相似文献

The object of this paper is to assess the effects of fitting a model of the wrong order to a time series which is generated by an autoregressive moving–average process. The method is to examine the spectral density functions which are indicated by the probability limits of the least–squares estimators of the misspecified models. The least–squares estimates are asymptotically equivalent to the maximum–likelihood estimates.
The experiments reported in this paper suggest that, if the spectral density function of the data–generating process displays prominent modes, then there is a danger of being seriously misled about the nature of the process whenever one fits a model with too few parameters. It also transpires that, in such cases, the criterion function is liable to have several local minima.
Autoregressive moving–average models are being used increasingly in object detection applications where the spectrum of a signal serves to identify the nature of its source. Our results suggest that radical misidentifications can result from the use of incorrectly parametrised models. 相似文献

近年来,网络借贷平台发展迅速,作为一个特殊的经济贷款模式,P2P网络借贷以其自身借贷条件低、手续便利、经济实惠等特点,获得了许多个人或是小微企业的青睐,从而使P2P网络贷款迅速发展壮大。当今,我国还没有一部统一的法律来规范P2P网络借贷平台。在P2P网络借贷平台活跃发展的今天,规定空白会滋生大量网络借贷违法行为的出现,不利于国民经济以及P2P行业的发展。因此,认清网络借贷平台的风险与加强对其的监管是当前一项重要的任务。 相似文献
