Toward a dynamic perspective on exploative and exploitative innovation activities: a longitudianl study of innovation in the wind blade industry

Innovation requires a combination of explorative and exploitative innovation\ud activities. Previous studies have provided valuable insights in the antecedents of investing in explorative and exploitative activities, the structural governance of exploration and exploitation and the performance implications of engaging in exploration and exploitation. These studies are dominated by cross-sectional research, largely ignoring the evolution of exploration and exploitation over time. Several scholars, however, provide first indications that the allocation of time and resources across exploration and exploitation might change over time. In order to examine the dynamics of explorative and exploitative innovation activities, we conducted an indepth case study in one particular company in the wind blade industry, applying a novel approach to measure the evolution of the amount of R&D resources allocated to explorative and exploitative activities over a 5 year time period. Our results show that the relative amount of resources and time invested in exploration versus exploitation is not static, but changes over time. The pattern of the evolution of exploration and exploitation at our case company shows phases in which exploration and exploitation activities are well balanced, and phases where one type of innovation dominates innovation activities. Based on additional qualitative data we found first indications of antecedents of the dynamics of exploration and exploitation. Together, our findings provide an interesting starting point for future research on the antecedents, structural governance and performance implications of the evolution of exploration and exploitation over time

Exploitation of Labour and Exploitation of Commodities: A "New Interpretation"

In the standard Okishio-Morishima approach, the existence of profits is proved to be equivalent to the exploitation of labour. Yet, it can also be proved that the existence of profits is equivalent to the ‘exploitation’ of any good. Labour and commodity exploitation are just different numerical representations of the productiveness of the economy. This paper presents an alternative approach to exploitation theory which is related to the New Interpretation (Duménil 1980; Foley 1982). In this approach, labour exploitation captures unequal social relations among producers. The equivalence between the existence of profits and labour exploitation holds, whereas it is proved that there is no relation between profits and commodity ‘exploitation’.Exploitation, Profits, Generalised Commodity Exploitation Theorem, New Interpretation

Sex Trafficking: Psychoeducational Interventions Relevant to Parent-Child Attachment Relationships

A brief history of adolescent sex exploitation. Topics include a definition of adolescent sex trafficking exploitation, statistics on sex trafficking exploitation globally and in the US, and risk factors of adolescent sex trafficking exploitation. The presenters will also explain the Parent-Child attachment relationship and the impact it has on child/adolescent behaviors (that may increase/decrease risk factors) as well as psychoeducational interventions for parents

Objectivist versus Subjectivist Approaches to the Marxian Theory of Exploitation

This paper analyses two central issues in exploitation theory. First, the appropriate definition of individual and aggregate measures of exploitation is discussed. Second, the relation between profits and exploitation (the so-called Fundamental Marxian Theorem) is analysed. A general framework for the analysis of exploitation in the context of convex cone economies is proposed and various alternative equilibrium concepts are discussed. The limits of subjectivist approaches to exploitation, which crucially depend on agents' preferences, are shown. An objectivist approach to exploitation, which is related to the socalled 'New Interpretation' (Dumenil, 1980; Foley, 1982) is proposed. It is argued that it captures the core intuitions of exploitation theory and that it provides appropriate indices of individual and aggregate exploitation. Further, it is shown that it preserves the Fundamental Marxian Theorem in general economies.Exploitation, Fundamental Marxian Theorem, general convex cone economies

Vocations, Exploitation, and Professions in a Market Economy

In a market economy, members of professions—or at least those for whom their profession is a vocation—are vulnerable to a distinctive kind of objectionable exploitation, namely the exploitation of their vocational commitment. That they are vulnerable in this way arises out of central features both of professions and of a market economy. And, for certain professions—the care professions—this exploitation is particularly objectionable, since, for these professions, the exploitation at issue is not only exploitation of the professional’s vocational commitment but also of her even more basic commitment to morality

Exploitation dynamics of fish stocks

I address the question of the fluctuations in fishery landings. Using the fishery statistics time-series collected by the Food and Agriculture Organization of the United Nations since the early 1950s, I here analyze fishing activities and find two scaling features of capture fisheries production: (i) the standard deviation of growth rate of the domestically landed catches decays as a power-law function of country landings with an exponent of value 0.15; (ii) the average number of fishers in a country scales to the 0.7 power of country landings. I show how these socio-ecological patterns may be related, yielding a scaling relation between these exponents. The predicted scaling relation implies that the width of the annual per capita growth-rate distribution scales to the 0.2 power of country landings, i.e. annual fluctuations in per capita landed catches increase with increased per capita catches in highly producing countries. Beside the scaling behavior, I report that fluctuations in the annual domestic landings have increased in the last 30 years, while the mean of the annual growth rate declined significantly after 1972.Comment: 27 pages, 19 figure

Symmetries in planning problems

Symmetries arise in planning in a variety of ways. This paper describes the ways that symmetry aises most naturally in planning problems and reviews the approaches that have been applied to exploitation of symmetry in order to reduce search for plans. It then introduces some extensions to the use of symmetry in planning before moving on to consider how the exploitation of symmetry in planning might be generalised to offer new approaches to exploitation of symmetry in other combinatorial search problems

Do sports stadiums generate crime on days without matches? A natural experiment on the delayed exploitation of criminal opportunities

Crime pattern theory claims that busy places generate crime through immediate and delayed exploitation. In delayed exploitation, offenders notice criminal opportunities during opening hours but return to exploit them later. This study investigates delayed exploitation by testing whether soccer stadiums locally increase police recorded property crime on non-game days. A soccer stadium closure created a natural experiment. We estimate linear regression difference-in-difference models to compare crime rates on non-game days around the stadium, before and after the closure. The closure reduced non-game day property crime beyond the citywide property crime drop. We conclude that criminogenic effects of busy places extend beyond their opening hours, confirming the delayed exploitation mechanism, and that crime prevention strategies should also target these places outside opening hours

Simple threshold rules solve explore/exploit trade‐offs in a resource accumulation search task

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade‐offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold‐based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non‐decreasing thresholds. Decreasing threshold strategies that “front‐load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration
