Are the learning procedures of genetic algorithms (GAs) able to generate optimal architectures for artificial neural networks (ANNs) in high frequency data? In this experimental study, GAs are used to identify the best architecture for ANNs. Additional learning is undertaken by the ANNs to forecast daily excess stock returns. No ANN architectures were able to outperform a random walk, despite the finding of non-linearity in the excess returns. This failure is attributed to the absence of suitable ANN structures and further implies that researchers need to be cautious when making inferences from ANN results that use high frequency data.

We study the empirical determinants of the Chinese renminbi (RMB) covered interest differential. The canonical macroeconomic variables including capital flight and the factors that affect country risk, and a few China-specific regulatory and institutional factors are considered. It is found that the effects of these canonical macroeconomic variables on the RMB covered interest differential are largely consistent with those reported in the literature. Further, the covered interest differential was affected by China's general capital control policy and its exchange rate reform program, but not its political risk index. The effects of these explanatory variables on the covered interest differential appear to work mainly via the forward premium rather than the interest rate differential component. The results are largely the same across the onshore and offshore RMB forward rates that cover different sample periods.

This chapter considers the lag structures of dynamic models in economics, arguing that the standard approach is too simple to capture the complexity of actual lag structures arising, for example, from production and investment decisions. It is argued that recent (1990s) developments in the the theory of functional differential equations provide a means to analyze models with generalized lag structures. The stability and asymptotic stability of two growth models with generalized lag structures are analyzed. The chapter's penultimate section includes a speculative discussion of time-varying parameters.

The paper extends the organizational learning framework: Structural-Functional (SF)-single-loop or Conflictual-Radical (CR)-double-loop learning to the management accounting literature. The sociological approach of organizational learning is utilized to understand those contingent factors that can explain why management accounting innovations succeed or fail in organizations.

We view learning as enhancing an organization’s strategic competitive advantage by making it better able to adopt and diffuse innovation in respond to changes in its environment in order to manage improved performance. The success of management accounting innovations is contingent upon whether its learning process involves SF-single-loop or CR-double-loop learning to adopt and diffuse process innovation.

The paper suggests that the learning strategy that the organization chooses is the reason why some management accounting innovations are more successfully adopted than others and why some innovations are easily diffused in some organizations but not in others. We propose that the sociological approaches to learning provide an alternative framework with which to better understand the adoption and diffusion of process innovations in management accounting systems.

It has become evident that management accounting researchers need to pay particular attention to an organization’s approach to adoption and diffusion of innovation strategies, particularly when they are designing and implementing process innovation programs for an organization. According to Schulz (2001), there are two interrelated stages of the learning that can shape the outcome of the innovation process in an organization. The first stage is related to the acquisition/production (adoption) of knowledge that results in gathering information, codification, and exploration. This is followed by the second stage which is the distribution or dissemination (diffusion) processes. When these two stages – adoption and diffusion – are applied within an accounting context, they address issues that are commonly associated with the successes and/or failures of management accounting innovations.

Although innovation involves learning, the nature of the learning process does not completely describe the manner in which an innovation affects the organization. Accordingly, we suggest that the two interrelated organizational sociological dimensions of innovations processes, namely, (1) the adoption and diffusion theories of Rogers (1971 and 1995), to approach organizational learning, and (2) the SF (single loop) and CR (double loop) approaches to learning be used simultaneously to describe management accounting innovations.

When an innovation is implemented, it initially can be introduced as an incremental change, one that can be limited in both in its scope and its breadth of administrative changes. This means that situations which are most likely to benefit from its initiation can serve as the prototype for its adoption by the organization. If successful, this can be followed by systemic accounting innovations to instituting broader administrative changes within the existing accounting reporting and control systems.

Our theoretical understanding of subjective well-being in the workplace is incomplete without a dynamic understanding of antecedents and outcomes of subjective well-being. While between-person differences provide useful information about employee outcomes, these differences do not provide information about the relationships between subjective well-being and employee outcomes that evolve over time and across situations. In this paper, we discuss specific statistical methods within the nomothetic and idiographic perspectives that can support dynamic research on subjective well-being in the workplace and outline unanswered contemporary questions regarding structure, processes, and dynamics of subjective well-being that may be addressed with these methods reviewed; some of which were proposed in early research but progressed slowly due to a lack of adequate methods. This discussion highlights how idiographic methods from outside organizational psychology can be applied to the study of worker subjective well-being to strengthen this dynamic approach in a way that addresses limitations associated with reliance on between-person models.

I review the burgeoning literature on applications of Markov regime switching models in empirical finance. In particular, distinct attention is devoted to the ability of Markov Switching models to fit the data, filter unknown regimes and states on the basis of the data, to allow a powerful tool to test hypotheses formulated in light of financial theories, and to their forecasting performance with reference to both point and density predictions. The review covers papers concerning a multiplicity of sub-fields in financial economics, ranging from empirical analyses of stock returns, the term structure of default-free interest rates, the dynamics of exchange rates, as well as the joint process of stock and bond returns.

This chapter theorises the Internet in Greece by placing it at the centre of Greek media offering a political economy which recasts it in a culturalist fashion. To achieve this, it critically addresses the country's alleged lag in cyberspace and asks why the Internet's hegemonic role in the advance of neoliberal policies and technoliberalism worldwide was never performed in Greece. It places the countrywide disdain for the technoliberal subject at the core of understanding of why the web mediations where so neatly denied over three decades across industry, policy and research. It centres around Internet remediations to argue that the Internet in Greece has been conceptualised as a nonmedia through the idea of lagging behind, essentially a construct veiling neoliberalism at work. It situates the advent of the web in Greece's media boom to argue that media power, as articulated in Greece, necessarily excluded the web, fetishising terrestrial broadcasting on the way to the neoliberal dismantling of culture, the media and everyday life, way before the Troika.
