The discussion about business models has gained considerable attention in the last decade. Business model frameworks have been developed in the literature as management methods helping companies to comprehend and analyse their current business logic and guide the deployment of new strategies. In response to calls for a deeper understanding of the application of a business model approach to product-service systems (PSS), this study develops a two-level hierarchical framework that (i) includes a set of components with pertinent, second-order variables to take into account when undergoing the shift from products to solutions; (ii) supports industrial companies, especially SMEs, in designing their future business model and in consistently planning the actions needed to implement it. The framework was applied and refined within real-life settings. The application to KINE – a robot solutions supplier – shows how key challenges faced by servitization firms may be thoroughly addressed through the adoption of a business model perspective.  相似文献

In this introductory essay to the special issue on civil society in authoritarian and hybrid regimes, we review core themes in the growing literature on shrinking or closing space for civil society. We discuss the role of civil society organizations (CSOs) as agents of democratization and note the emergence of dual, at times apparently conflicting policy postures within authoritarian regimes (restriction and repression for some CSOs vs. financial support and opportunities for collaboration for others). We posit that different conceptual perspectives applied to civil society can help account for the duality of authoritarian postures and examine repercussions for three key subgroups of CSOs: claims-making (or advocacy) NGOs, nonprofit service providers and regime-loyal NGOs supporting often populist and nationalist discourses.

The expansion of global supply chains (GSCs) has increasingly disconnected the location of jobs from the demand supporting them, both geographically and in terms of sector. Using data from the World Input–Output Database, the authors examine these linkages across 40 countries over the period 1995–2013, expanding on earlier analysis published by the ILO, and provide evidence of the number of GSC‐related jobs in terms of job location–export destination combinations. Their findings point to changing patterns in demand and supply of GSC‐related jobs, increasing the role of China as a demand generator, reinforcing production linkages between emerging economies and increasing the number of service jobs dependent on manufacturing GSCs.  相似文献

Using South African household expenditure data, we analyze how the spending of a household on visible goods, such as jewelry and clothes, depends on the distribution of income within its social group. We find that this spending is positively correlated with the share of peers who possess a similar income level to the household, what we dub the “local income share.” Moreover, we find that the spending of a household on visible goods is positively correlated with the average income of peers that are poorer than this household. We interpret this as evidence for cascade effects through which income changes among the poorest in the social group can trigger adjustments in the visible spending patterns of the wealthy. In line with previous research (Charles et al. 2009), we also find that visible spending of a household is negatively correlated with the average income of its social group. We present a simple model of status competition based on Hopkins and Kornienko (2004) that synthesizes these effects and can account for our results. (JEL D12, D31, O12)  相似文献

Regulatory problems in infancy and toddlerhood have previously been associated with an increased risk of developing attention problems in childhood. We hypothesized that early regulatory problems are associated with attention problems via reduced inhibitory control. This prospective study assessed 1,459 children from birth to 8 years. Crying, feeding, and sleeping problems were assessed at 5 and 20 months via parent interviews and neurological examinations. At 20 months, inhibitory control was tested with a behavioral (snack delay) task. Attention regulation was assessed at 6 and 8 years using multiple instruments and informants. Detrimental effects of crying, feeding, and sleeping problems on attention regulation were partly mediated by children's ability to inhibit unwanted behaviors (β = ?0.04, = 0.013). Accounting for cognition diminished this indirect effect (β = ?0.01, = 0.209). Instead, the effects of crying, feeding, and sleeping problems on attention regulation were fully mediated by children's cognitive functioning (β = ?0.10, < 0.001). These results support that inhibitory control abilities partly mediate effects of crying, feeding, and sleeping problems. However, these effects may be accounted for by children's general cognitive abilities. Early regulatory problems may set infants on a course of under control of behavior into school age, and such trajectories are highly associated with general cognitive development.  相似文献

ABSTRACT: After unification, East German GNP dropped severely, total employment fell to about two thirds of the former level. Long-term labour market prospects remain poor. From the very beginning up to now, labour market policy (short-time work, early retirement schemes, work creation measures, further training and retraining) absorbed much of the surplus labour supply. Regulations were changed to allow for‘“mega-measures” (contrasting the traditional individual approach). A new co-financing model links work-creation measures more closely to regional structural policy. A labour market infrastructure was built up in a short time, including new elements such as‘“employment promotion companies” and‘“reconstruction agents“.  相似文献

The time series of counts observed in practice often exhibit overdispersion. The INGARCH(p, q) models are able to describe integer-valued processes with overdispersion. Known properties of these models, however, are nearly exclusively restricted to the special case p = q = 1. In this article, we derive a set of equations from which the variance and the autocorrelation function of the general case can be obtained. We investigate the purely autoregressive INGARCH(p, 0) models and show that they are closely related to the standard AR(p) models. For p = 1, we determine the marginal distribution in terms of its cumulants. A real-data example highlights potential fields of application of the INGARCH(p, 0) models.  相似文献

Changing your role models: Social learning and the Engel curve   总被引:1,自引:0,他引:1  
By relating Engel curves and social learning, we explain the existence of differently shaped Engel curves—an interesting phenomenon in the theory of demand. A formal approach to cultural learning within a population of consumers accounts for some cognitive foundations of these demand patterns. We find that a changing influence of an individual's role models due to her increasing income, which entails new reference groups providing social identity, leads to the diffusion of new consumption behaviors. Thereby, the resulting Engel curves’ shape depends on the underlying learning dynamics. The approach contributes to an explanation of structural change and economic development.  相似文献

Traditionally, discussion about neuroimaging focuses on methodological improvement and neurobiological findings. In current psychiatric neuroimaging, the research focus broadens and includes concepts such as the self, personality, well-being, and psychiatric disease. This calls for the inclusion of disciplines like psychology and philosophy in a dialogue with neuroscience. Furthermore, it raises the question of how theories from these areas relate to neuroimaging findings: are results generated by objective data independent of theories? Is there an epistemological priority for the theories used for generating hypotheses and for interpreting the results? Or do theoretical concepts and neuroimaging data influence each other? In this paper, we will discuss these positions concerning the priority of concepts and data in neuroimaging and provide arguments for an interdependence of concepts and data. An awareness of these considerations may help professionals from the life sciences and humanities as well as laypersons to avoid misunderstandings and oversimplifications.  相似文献
