Application Service

This paper draws from the findings of a large-scale empirical research program on the global application service provider (ASP) industry funded by research grants from the European Commission (EC) and the Engineering and Physical Sciences Research Council (EPSRC). A conceptual framework consisting of a taxonomy of ASPs is used to demonstrate the different market segmentation strategies adopted by ASPs for competing in this fledgling and turbulent industry. Drawing from empirical research carried out in the US and Europe, the paper evaluates ASP strategies for deploying, hosting, managing and enabling software applications on behalf of their customers. The ASP business model is advocated as an attractive value proposition for SMEs, dot.com companies and other start-up firms seeking hyper-growth. Yet the evidence so far suggests a slow start to the ASP market as few reference sites demonstrating best practice exist. ASPs will therefore need to re-evaluate their strategies if they are to convince potential customers of the benefits of application outsourcing. Against this background, the paper evaluates the benefits and risks of the ASP model.

PurposeThe purpose is to understand why contract instability occurs when small landowners lease their land to large landholders.Design/methodology/approachThe authors develop a contract theoretical model to understand the stability problem in the farmland lease contract in China, where most landowners are small landholders.FindingsResults from the doubly robust estimation method used on randomly selected interview data from 552 households in nine provinces of China indicate that contract instability can arise endogenously when large landholders sign a contract. The authors conclude that a suitable rent control regime or contract enforcement may be necessary to promote a large-scale farmland transfer in China.Originality/valueThe authors develop a contract theoretical model and apply it to the land rental market in China. Data used are original and collected from farmers located in nine provinces of China.

This article traces the evolution and demise of the postwar model of job quality. This model evolved in the context of theories of sheltered employment. It tied assumptions about job quality to the idea that the economy was separable into a stable and unstable segment. Jobs were typically described in terms of a dual structure, in which workers were either employed in the core sector with high employment security and high relative wages or the periphery, where jobs were low paying and unstable. Industrial jobs in large scale mass manufacturing enterprises, in this context, served as a benchmark for individual job quality. When the assumption of a stable sector of the economy became untenable, the concept of labour market shelters was modified and new models which accounted for flexibility in production were developed. This modification process progressively eroded the core of labour market segmentation theory. By the 1990s, both conceptual considerations and empirical evidence dismissed older simplistic concepts of stable demand, and suspended key assumptions about the cumulative nature of job quality. In terms of a Sociology of Knowledge, we witness the gestation and deterioration of an integrated set of economic propositions paralleling real and/or perceived changes in the economic environment.

The Impact

Abstract Background Interrupted time series analysis is increasingly used to evaluate the impact of large-scale health interventions. While segmented regression is a common approach, it is not always adequate, especially in the presence of seasonality and autocorrelation. An Autoregressive Integrated Moving Average (ARIMA) model is an alternative method that can accommodate these issues. Methods We describe the underlying theory behind ARIMA models and how they can be used to evaluate population-level interventions, such as the introduction of health policies. We discuss how to select the shape of the impact, the model selection process, transfer functions, checking model fit, and interpretation of findings. We also provide R and SAS code to replicate our results. Results We illustrate ARIMA modelling using the example of a policy intervention to reduce inappropriate prescribing. In January 2014, the Australian government eliminated prescription refills for the 25 mg tablet strength of quetiapine, an antipsychotic, to deter its prescribing for non-approved indications. We examine the impact of this policy intervention on dispensing of quetiapine using dispensing claims data. Conclusions ARIMA modelling is a useful tool to evaluate the impact of large-scale interventions when other approaches are not suitable, as it can account for underlying trends, autocorrelation and seasonality and allows for flexible modelling of different types of impacts.

Relevance. In terms of implementing large production projects, the Arctic is one of the most challenging regions in the world. This is due to geographic remoteness, extreme temperatures, difficult ice conditions, a vulnerable environment and the presence of indigenous people concerned about any outside interference. Global experience shows that the development of the Arctic territories is untenable without participation of large corporations and their implementation of large-scale Arctic projects. The capabilities of medium-sized businesses to influence the development of the Arctic territories are incomparable with the capabilities of large corporate structures in terms of their system-forming effects. At the same time, ensuring the necessary investments for the development of the Arctic territories requires improving the state regulation of subsoil use from the position of strengthening the incentive nature of the system of measures used. The purpose of the study is to generalize and analyze foreign experience in regulating the process of developing subsoil resources in foreign Arctic countries. Research methods – a systematic approach, generalizations, comparative analysis, comparisons, etc. Results. The experience of subsoil use regulation in the Arctic territories in the USA (Alaska), Canada, Norway, Denmark and Russia is generalized and analyzed. It has been determined that the approaches to regulating the process of developing subsoil resources are correlated with the state structure of the countries: unitary or federal. The form of subsoil ownership in each of the listed countries and the procedure for granting subsoil plots for use are considered. Most attention is paid to the economic mechanism of regulation. It is proved that, depending on the economic model, measures to support corporate business and economic incentives used by countries to achieve strategic goals in the Arctic have many differences, but a similar nature. Special tax regimes, rent control measures, financial support, which is in the nature of investments, and other financial instruments are used as incentives. The specificity of the tax policy of each of the countries under consideration is disclosed, a number of factors influencing the amount of royalties, the procedure for the distribution of collected taxes on corporations in the Arctic zone between the budgets of the federation and provinces, etc., are determined. Common tools for all states have been identified and the existence of coordination procedures has been confirmed to harmonize the interests of corporations and the state. The experience of taxation of regional corporations in the Arctic territories of Russia and its disadvantages are briefly highlighted. Conclusions. The imperfection of the institutional framework of the Russian Arctic requires the adoption of new legislative acts, as well as changes in taxation, the implementation of a system of incentives from the state. It is advisable to use many elements of the economic mechanism of foreign countries to expand the capabilities of corporations involved in the development of Arctic subsoil resources.

AbstractUnusual short-period comet 29P/Schwassmann-Wachmann 1 inspired many observers to explain its unpredictable outbursts. In this paper large scale structures and features from the inner part of the coma in time periods around outbursts are studied. CCD images were taken at Whipple Observatory, Mt. Hopkins, in 1989 and at Astronomical Observatory, Modra, from 1995 to 1998. Photographic plates of the comet were taken at Harvard College Observatory, Oak Ridge, from 1974 to 1982. The latter were digitized at first to apply the same techniques of image processing for optimizing the visibility of features in the coma during outbursts. Outbursts and coma structures show various shapes.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.
