AbstractThe paper deals with the so-called Preference Theory developed in the works of Theo Vennemann and Robert Murray within the scope of historical phonology. The first part of the paper examines the constituting assumptions and claims of the theory. The goal of the preference-based historical phonology – uncovering the motivation for sound changes which the Neogrammarian methodology can merely describe – will be achieved only if the universal preferences are reliably established. It is shown that the procedures which are employed to extract the universal preferences from empirical data do not lead to reliable results. The reason for this is the failure of the Preference Theory to distinguish in a non-arbitrary way between the alleged universally preferred structures and the mere by-products of sound changes with different or unknown motivation. The second part of the paper examines a recently suggested modification of the traditional notion of the exceptionlessness of sound changes. According to Vennemann, the traditional exceptionless sound changes are in fact to be considered as non-exclusive tendencies towards universally more preferred phonological structures. The paper shows that this position is neither based on the core assumptions of the Preference Theory nor supported by the adduced empirical evidence.

The Way

My goal in writing this book is to change the agenda of the field of cognitive development. In particular, I want to promote greater attention to the question that I believe is inherently at the core of the field: How do changes in children’s thinking occur? Focusing on change may not sound like a radical departure from current practice, but I believe it is. It will require reformulation of our basic assumptions about children’s thinking, the kinds of questions we ask about it, our methods for studying it, the mechanisms we propose to explain it, and the basic metaphors that underlie our thinking about it. That modifications of all of these types are being proposed as a package is no accident. Just as existing approaches have directed our attention away from the change process, so may new ones lead us to focus squarely on it. This concluding chapter summarizes the kinds of changes in assumptions, questions, methods, mechanisms, and metaphors that I think are needed. My initial decision to write this book was motivated by a growing discomfort with the large gap between the inherent mission of the field—to understand changes in children’s thinking—and most of what we actually have been studying. As I thought about the problem, I came to the conclusion that existing assumptions, methods, and theories acted in a mutually supportive way to make what we typically do seem essential, and to make doing otherwise—that is, studying change directly—seem impossible. Even approaches that proclaimed themselves to be radical departures from traditional theories maintained many fundamental assumptions of those theories. An increasing body of empirical evidence, however, indicates that some of the assumptions are wrong and that the way in which they are wrong has led us to ignore fundamental aspects of development. In this section, I describe prevailing assumptions regarding variability, choice, and change, and propose alternatives that seem more consistent with empirical data and more useful for increasing our understanding of how changes occur.

Although empirical evidence may provide a much desired sense of certainty amidst a pandemic characterised by uncertainty, the vast gamut of available COVID-19 data, including misinformation, has instead increased confusion and distrust in authorities’ decisions. One key lesson we have been gradually learning from the COVID-19 pandemic is that the availability of empirical data and scientific evidence alone do not automatically lead to good decisions. Good decision-making in public health policy, this paper argues, does depend on the availability of reliable data and rigorous analyses, but depends above all on sound ethical reasoning that ascribes value and normative judgement to empirical facts.

Housing Allocation

The Swedish rent control system creates a white market for swapping rental contracts and a black market for selling rental contracts. Empirical data suggests that in this black-and-white market some people act according to utility functions that are both discontinuous and locally decreasing in money. We discuss Quinzii's theorem for the nonemptiness of the core of generalized house-swapping games, and show how it can be extended to cover the Swedish game. In a second part, we show how this theorem of Quinzii and her second theorem on nonemptiness of the core in two-sided models are both special cases of a more general theorem.

Musical Scales

Musical scales are used throughout the world, but the question of how they evolved remains open. Some suggest that scales based on the harmonic series are inherently pleasant, while others propose that scales are chosen that are easy to communicate.However, testing these theories has been hindered by the sparseness of empirical evidence. Here, we assimilate data from diverse ethnomusicological sources into a cross-cultural database of scales. We generate populations of scales based on multiple theories and assess their similarity to empirical distributions from the database. Most scales tend to include intervals which are close in size to perfect fifths (“imperfect fifths”), and packing arguments explain the salient features of the distributions. Scales are also preferred if their intervals are compressible, which may facilitate efficient communication and memory of melodies. While scales appear to evolve according to various selection pressures, the simplest, imperfect-fifths packing model best fits the empirical data.

Inalienable Rights

Abstract: The overwhelming majority of contemporary theories of justice is grounded in the rationalist tradition (Frazer, 2010). As a consequence, political philosophers such as John Rawls (1971) have interpreted moral systems as axiomatic, substantially based on concepts of inalienable rights and duties—usually guided by the core value attached to human dignity. Once ethicists started working under an axiomatic framework, empirical evidence has become less and less useful. This road has been conducive to the current prevalence of ideal theories in the field. On a dissonant note, recent debate in political philosophy has rekindled our attention to the development of nonideal theories of justice. Yet before one argues in favor of nonideal (or comparative) theories of justice, one has to be certain that all arguments against the broader incorporation of empirical evidence in the development of political philosophical theories are not valid. Therefore the focus of the present paper is the assessment—and dismissal—of these arguments.Keywords: Theories of Justice; Nonideal Theories; Empirical Evidence; MethodologyResumo: A grande maioria das teorias de justiça contemporâneas se baseiam na tradição racionalista (Frazer, 2010). Como consequência, filósofos políticos como John Rawls (1971) têm interpretado sistemas morais como axiomáticos, baseados substancialmente em conceitos de direitos e deveres inalienáveis – geralmente guiados pelo valor central concedido à dignidade humana. Uma vez que os eticistas começaram a utilizar uma moldura axiomática, as evidências empíricas se tornaram cada vez menos úteis. Esse caminho foi relevante para a atual prevalência de teorias ideais nesse campo. De maneira dissonante, o debate recente na filosofia política reacendeu a atenção para o desenvolvimento de teorias de justiça não ideais. Contudo, antes que alguém argumente em favor de teorias de justiça não ideais (ou comparativas), é preciso estar certo de que todos os argumentos contrários a uma incorporação mais ampla de evidências empíricas no desenvolvimento de teorias políticas filosóficas não são válidos. Portanto, o foco deste artigo é a avaliação – e rejeição – destes argumentos.Palavras-chave: Teorias de justiça; Teorias não ideais; Evidência empírica; Metodologia.

Snmp Protocol

Abstract Cloud computing has seen rapid growth and environments are now providing multiple physical servers with several virtual machines running on those servers. Networks have grown larger and have become more powerful in recent years. A vital problem related to this advancement is that it has become increasingly complex to manage networks. SNMP is one standard which is applied as a solution to this management of networks problem. This work utilizes SNMP to explore the capabilities of SNMP protocol and its features for monitoring, control and automation of virtual machines and hypervisors. For this target, a stage-wise solution has been formed that obtains results of experiments from the first stage uses SNMPv3 and feed to the second stage for further processing and advancement. The target of the controlling experiments is to explore the extent of SNMP capability in the control of virtual machines running in a hypervisor, also in terms of energy efficiency. The core contribution based on real experiments is conducted to provide empirical evidence for the relation between power consumption and virtual machines.

Quantitative analysis of negotiation concession behavior is performed based on empirical data with the purpose of providing simple and intuitive decision support in electronic negotiations. Previous work on non-linear concave preferences and subsequent concession crossover provides a theoretical basis for the model. The authors propose a model which quantifies the remaining concession potential for each issue and a generalization of the model which permits the memory/decay of past concessions. These models permit the analysis of negotiators' concession behavior. Using the proposed models, it was possible to quantitatively determine that negotiators in the authors' negotiation case exhibit concession crossover issues and thus have a tendency to give concessions on issues with the most remaining concession potential. This finding provides empirical evidence of concession crossover in actual concessions and the corresponding model permits the design of a simple and intuitive prediction methodology, which could be used in real world negotiations by decision support systems or automated negotiation agents.

Practical Implications

A common observation in the digital age is that new technologies are making people’s behaviors, decisions, and preferences more visible. For scholars who study organizations and their effects upon society, increased information visibility raises the hope that organizations might become more transparent. Typically, we assume that increased information visibility will translate into high levels of organizational transparency, but we lack empirical evidence to support this assumption. Our ability to gather data on this important topic is limited because there have been few reliable ways to assess organizational information visibility. To remedy this problem, we develop and validate the Information Visibility Scale to measure the core aspects of information visibility. We then employ the scale to test the relationship between information visibility and transparency. We discuss the theoretical and practical implications of the scale and consider the limitations and further research possibilities that the scale construction and validation suggest.

Satisfactory Theory

Empirical data are confronted with different hypotheses on the origin of comets. The hypotheses are classified into three categories: 1) Comets were condensed from the solar nebula and ejected later into the Oort’s cloud. 2) Comets were condensed in situ, more or less recently, on their present trajectories; 3) Reversing the arrow of time in the traditional evolution of comets. Only two hypotheses, both from the first category, are found to be in agreement with all empirical data. The first hypothesis explains the origin of the Oort’s cloud by the perturbations of the giant planets (mainly Uranus and Neptune and possibly Pluto) on a ring of proto-comets, during the final accretion stages of the solar system. The second hypothesis uses the fast mass loss of the solar nebula to expell an outer ring of proto-comets into elliptic trajectories. Although no empirical evidence requests that the Oort’s cloud be older than a few million years, its matter is not likely to be from a different reservoir than solar system stuff, and no satisfactory theory explains its formation more recently than 4,5 billion years ago.

Effective Conservation

SUMMARYNo-take marine reserves are widely recognized as an effective conservation tool for protecting marine resources. Despite considerable empirical evidence that abundance and biomass of fished species increase within marine reserve boundaries, the potential for reserves to provide fisheries and conservation benefits to adjacent waters remains heavily debated. This paper uses statistical and population models to evaluate published empirical data on adult spillover from marine reserves and shows that spillover is a common phenomenon for species that respond positively to reserve protection, but at relatively small scales, detectable on average up to 800 m from reserve boundaries. At these small scales, local fisheries around reserves were likely unsustainable in 12 of 14 cases without the reserve, and spillover partially or fully offsets losses in catch due to reserve closure in the other two cases. For reserves to play a role in sustaining and replenishing larger-scale fished stocks, networks of reserves may be necessary, but as few exist this is difficult to evaluate. The results suggest reserves can simultaneously meet conservation objectives and benefit local fisheries adjacent to their boundaries.
