Germany is considered to be a pioneer of social security systems; nonetheless, globalization and demographic changes have put enormous pressure on them. A solution is not yet in sight as the debate on the future of the German social security systems still lacks consensus. We argue that ideas matter and that the debate can benefit from a deeper reflection on the concept of social security. This objective is pursued along two lines. First, we take a historical perspective and reconstruct the (...) development of Germany's social security systems. Second, we scrutinize from a theoretical perspective how social security is conceptualized in public and theoretical debates. Behind the various positions, we identify four basic ideal types. We then analyze how these ideal types account for the benefits of social security systems and what role they assign to corporations in providing social security. While two ultimately reinforce potential conflicts between different groups in society, the other two ideal types reveal possible benefits for all. The last ideal type actually conceptualizes social security systems as insurance that fosters risky but overall productive investments in human and other forms of capital. Therefore, it can be shown that social security systems are not necessarily threatened by globalization and that incentives exist for corporations to invest in the provision of social security.

Natural selection is generally considered to be a process exclusive to the domain of biotic systems. In this paper, a universal, five phase set of dynamics are identified as a framework underpinning the natural selection that occurs in all processes, governing every interaction at every scale, from the quantum to the intergalactic. The theoretical model describes a two-tendency universe, where the tensions that exist between syntropy and entropy provide the context for functional synergies from which all matter and material systems (...) emerge, supporting a theory of general, biotic and cognitive evolution.

In this paper a formal framework is proposed in which variousinformative actions are combined, corresponding to the different ways in whichrational agents can acquire information. In order to solve the variousconflicts that could possibly occur when acquiring information fromdifferent sources, we propose a classification of the informationthat an agent possesses according to credibility. Based on this classification, we formalize what itmeans for agents to have seen or heard something, or to believesomething by default. We present a formalization of observations,communication actions, (...) and the attempted jumps to conclusions thatconstitutes default reasoning. To implement these informative actionswe use a general belief revision action which satisfies theAGM postulates; dependent on the credibility of the incominginformation this revision action acts on one or more parts ofthe classified belief sets of the agents. The abilities of agents formalizeboth the limited capacities of agents to acquire information, and the preference of one kind of information acquisition to another. A very important feature of our approach is that it shows how to integratevarious aspects of agency, in particular the (informational) attitudesof dealing with information from observation, communication and defaultreasoning into one coherent framework, both model-theoretically andsyntactically.

Much social theory takes for granted the core conceit of modern culture, that modern actors-individuals, organizations, nation states-are autochthonous and natural entities, no longer really embedded in culture. Accordingly, while there is much abstract metatheory about "actors" and their "agency," there is arguably little theory about the topic. This article offers direct arguments about how the modern (European, now global) cultural system constructs the modern actor as an authorized agent for various interests via an ongoing relocation into society of agency (...) originally located in transcendental authority or in natural forces environing the social system. We see this authorized agentic capability as an essential feature of what modern theory and culture call an "actor," and one that, when analyzed, helps greatly in explaining a number of otherwise anomalous or little analyzed features of modern individuals, organizations, and states. These features include their isomorphism and standardization, their internal decoupling, their extraordinarily complex structuration, and their capacity for prolific collective action. (shrink)

The results of two experiments are analyzed to find out how artistic expertise influences visual search. Experiment I comprised survey data of 1,065 students on self-reported visual memory skills and their ability to find three targets in four images of artwork. Experiment II comprised eye movement data of 50 Visual Literacy experts and non-experts whose eye movements during visual search were analyzed for nine images of artwork as an external validation of the assessment tasks performed in Sample I. No time (...) constraint was set for completion of the visual search task. A latent profile analysis revealed four typical solution patterns for the students in Sample I, including a mainstream group, a group that completes easy images fast and difficult images slowly, a fast and erroneous group, and a slow working student group, depending on task completion time and on the probability of finding all three targets. Eidetic memory, performance in art education and visual imagination as self-reported visual skills have significant impact on latent class membership probability. We present a hidden Markov model approach to uncover underlying regions of attraction that result from visual search eye-movement behavior in Experiment II. VL experts and non-experts did not significantly differ in task time and number of targets found but they did differ in their visual search process: compared to non-experts, experts showed greater precision in fixating specific prime and target regions, assessed through hidden state fixation overlap. Exploratory analysis of HMMs revealed differences between experts and non-experts in image locations of attraction. Experts seem to focus their attention on smaller image parts whereas non-experts used wider parts of the image during their search. Differences between experts and non-experts depend on the relative saliency of targets embedded in images. HMMs can determine the effect of expertise on exploratory eye movements executed during visual search tasks. Further research on HMMs and art expertise is required to confirm exploratory results.

These sixty contributions from researchers in ethology, ecology, cybernetics, artificial intelligence, robotics, and related fields delve into the behaviors and underlying mechanisms that allow animals and, potentially, robots to adapt and survive in uncertain environments. They focus in particular on simulation models in order to help characterize and compare various organizational principles or architectures capable of inducing adaptive behavior in real or artificial animals.

This book examines the criticism that modern business schools face and how these obstacles have evolved throughout history. Through historical, resource, and professional school contexts, it sheds light on the operating environment of the business school and the challenges endemic to various university-based professional schools, exploring the likelihood that potential interventions will result in success or failure. Business schools are often accused of inhibiting the practice of business by producing research that is irrelevant and does not address real concerns facing (...) managers. This book investigates these accusations by outlining the historical values on which academic institutions are based, the resources and funding available today, and comparisons to other professional schools which undergo a similar level of scrutiny. This extensive coverage will help academics, administrators, faculty, and policy makers with the tools to understand better the ill-will towards business schools in today's university structure, and ultimately to deliver on the benefits they provide to stakeholders.

Differences in the ability of students to judge images can be assessed by analyzing the individual preference order of images. To gain insights into potential heterogeneity in judgement of visual abstraction among students, we combine Bradley–Terry preference modeling and model-based recursive partitioning. In an experiment a sample of 1,020 high-school students ranked five sets of images, three of which with respect to their level of visual abstraction. Additionally, 24 art experts and 25 novices were given the same task, while their (...) eye movements were recorded. Results show that time spent on the task, the students’ age, and self-reported interest in visual puzzles had significant influence on rankings. Fixation time of experts and novices revealed that both groups paid more attention to ambiguous images. The presented approach makes the underlying latent scale of visual judgments quantifiable.
