Abstract
Donald Stokes’ approach to map the names of prominent scientists onto adiagram showing their impact on fundamental science and applied science is adopted and expanded to illustrate the dynamic interactions of the four nodes of the Cyclic Innovation Model (CIM). Tagging names of prototypical role models onto the four nodes and cycles of CIM increases the meta-level understanding of the fundamental concepts depicted by this innovation model. It also serves as a tool to validate the completeness of the model.

Abstract
Transient climate sensitivity relates total climate forcings from anthropogenic and other sources to surface temperature. Global transient climate sensitivity is well studied, as are the related concepts of equilibrium climate sensitivity (ECS) and transient climate response (TCR), but spatially disaggregated local climate sensitivity (LCS) is less so. An energy balance model (EBM) and an easily implemented semiparametric statistical approach are proposed to estimate LCS using the historical record and to assess its contribution to global transient climate sensitivity. Results suggest that areas dominated by ocean tend to import energy, they are relatively more sensitive to forcings, but they warm more slowly than areas dominated by land. Economic implications are discussed.

Abstract
Economic mobility means different things to different people, but four major classes of mobility measures have been identified in the literature: positional, directional, mobility as an equaliser of long-term earnings, and earnings risk (or flux). We illustrate some advantages of a multifaceted approach by comparing German and American earnings mobility using multiple indices from each of the four major classes for three panels of 10-year intervals. We anticipate and confirm that due to extensive differences in the German and American labour markets and in other social institutions that influence labour market outcomes, each country dominates in one facet of mobility but not in the others. Thus, a multifaceted approach contributes to a better understanding of the strengths and weakness of the two systems.

Abstract
Purpose – We make a case for bridging two types of logics – analytic and dialectic – for explaining processes of social-historical change, and maintain that a successful bridge between these two logics depends on a variety of conditions and most especially the type of analytic logic or model one employs for capturing dynamic processes.
Methodology/approach – Conventional models of social change processes typically presuppose ergodic social worlds and are problematic as analytic approaches generally and most certainly are not fertile grounds for feeding dialectic theorization. Instead, we propose modeling dynamic processes that begin by assuming a nonergodic social world – one in flux, one that is nonrepeating, one within which model process and parameter structures are historically contingent and change with time, one that is autocatalytic, creating and changing its own possibilities.
Findings – We develop the line of thinking adumbrated above and illustrate these modeling strategies with empirical examples from US labor movement history. Results from these examples lend much weight to our proposals. Thus, this chapter demonstrates that concerns about the use of ergodic assumptions and about greater use of dialectical reasoning when studying social processes are not idle speculations within theoretical commentaries but have practical consequences in the conduct of research and the building of better theory.
Research limitations/implications – To approximate such an approach, social scientists should avoid cross-sectionalist and longitudinal modeling strategies that presuppose stability and homogeneity in parameter and process structures. Homogeneity and stability in parameter and process structures should be demonstrated, not assumed.
Originality/value – Rather than accepting the alienated spheres of social science analytics and dialectic theory, our proposal presupposes nonergodic social worlds and takes pragmatic steps for estimating analytic models that are more amenable to dialectic reasoning. Models that take nonergodicity seriously not only have the potential to produce better, historically grounded analytics but are also best suited to bridge with dialectic logic, thus taking advantage of the strengths of both forms of logic.

Abstract
Networks and learning matter to small- and medium-sized enterprises (SMEs). Networks and learning are also further elaborations on the exploration–exploitation (EE) dilemma. Ambidexterity, that is, managing this apparent dilemma, can be difficult as a result of many constraints. One of these constraints is that of mutually exclusive network structures. Consequently, ambidexterity is the ability to change networks, depending on need using mixed data on four small companies formed as part of an undergraduate management class, I hypothesize how specific network properties of the advice-seeking relationship, including density, cohesion, centralization, and embeddedness, affect two outcomes. Specifically, early exploratory learning is proposed to be positively affected by less-dense networks that maintain cohesion without centralization and do not have relations embedded in other relations. In contrast, later exploitative learning should be associated with denser networks that also have higher cohesion, higher centralization, and greater embeddedness. The results provide some support for these hypotheses and suggest further research in two areas that will benefit SMEs. One, how do early networks affect learning mode? Two, how does the ability to rewire networks provide the relational infrastructure to shift from exploration to exploitation – that is, to be ambidextrous in the face of the exploration–exploitation tradeoff?

Abstract
The author develops a bilateral Nash bargaining model under value uncertainty and private/asymmetric information, combining ideas from axiomatic and strategic bargaining theory. The solution to the model leads organically to a two-tier stochastic frontier (2TSF) setup with intra-error dependence. The author presents two different statistical specifications to estimate the model, one that accounts for regressor endogeneity using copulas, the other able to identify separately the bargaining power from the private information effects at the individual level. An empirical application using a matched employer–employee data set (MEEDS) from Zambia and a second using another one from Ghana showcase the applied potential of the approach.

Abstract
Processual approaches to entrepreneurship have increasingly captured researchers’ interest. One such approach that tries to understand entrepreneurs in real time by looking with them, not at them, has been termed withness (Shotter, 2006). But how does one design a study that captures this experience of living in the flow? In this methodological reflection, we propose using the metaphor of warp and weft to think of grounded theory research designs that seek to approximate withness. To this end, we also reflect on our experience studying the unfolding processes in international new ventures and highlight the usefulness of multiple data collection instruments, notably diaries and interviews.

Abstract
This chapter examines interlocks among the governing boards of 12 leading policy-planning organizations and changes in the structure of this network between 1973 and 2000. Methods of multidimensional scaling and hierarchical clustering are used to construct topographical maps of the pattern of interlocks among policy-planning groups and their change over time. In contrast to the findings on corporate interlocking directorates, the study shows that board interlocks among policy-planning organizations are substantively meaningful and relatively stable at the dyadic level, although several changes in the topology of the network are also found. In all three decades, big-business “moderate-conservatives” like the Business Council and the Business Roundtable occupied the most central locations in the network. In the 1970s these organizations were linked with the “corporate liberals” to form the core cluster of the policy network. In the 1980s and 1990s the corporate liberals became relatively isolated from the core and their places were taken by several conservative groups. There was also a sharp rise in the cohesion of the network in the late 1970s and 1980s – a period that is widely seen as one of conservative political mobilization and heightened political unity among business elites. These changes in the structure of the policy network are consistent with and help to account for the rightward shift in U.S. state policy during this period.
