Impersonal Style and the Form of Experience in W. G. Sebald's The Rings of Saturn
No full textThis article argues that W. G. Sebald’s prose fiction reverses the traditional positioning of the witness as a point of singularity, and that it instead theorizes a relationship to the act of witnessing that, while anchored in personal experience, is imbued at its core with impersonal form. Using The Rings of Saturn as my central example, I demonstrate that it is the tension between the immediacy of first-person experience and the characteristic distance of Sebald’s style that makes possible the narrator’s attunement to the “traces of destruction” that he encounters during his walk, and to which he bears witness both in and through his narrative. Sebald’s witnessing, then, is less a relation between past and present or witness and event than it is a critical orientation that produces the imperative to bear witness as a function of the very permeability of these categories.Peer reviewe
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Managing the After Sales Logistic Network– A Simulation Study of a Spare Parts Supply Chain
No full textThe after-sales services and in particular the spare parts business have acquired, in recent years, a strategic role for firms manufacturing durable or capital goods, as they represent a source of revenue, profit and a mean to achieve customer satisfaction and retention. Nonetheless, the huge variety and the characteristics of the demand of spare parts make the configuration and management of the spare parts inventory and distribution systems critical decision areas for managers. These decisions, in fact, may lead to very different cost and service performance by the system itself. The case study analyzed concern a world player of heavy equipment based in Sweden. Its spare parts distribution system is described, and the paper analyzes the configuration and allocation decisions concerning a second European warehouse and the transfer to that warehouse of a set of suppliers. A simulation model has been developed in order to support these choices. Discrete event simulation is well suited for studies where time-dependant relations are analyzed. Supply Chain Simulation applied to the case study provides useful insights on the decision choices and the cost structure related to the spare parts distribution system
Managing the After Sales Logistic Network– A Simulation Study
No full textThe after-sales business has in recent years acquired a strategic role for firms manufacturing durable or capital
goods, as it represents a source of revenue, profit and a means to achieve customer satisfaction and retention.
The case study analysed in this article concerns a world player of heavy equipment based in Europe. This article
analyses the spare parts classification method adopted by the company, and the allocation decisions concerning a
second European warehouse and the transfer to that warehouse of a set of suppliers. A simulation model has
been developed in order to support these choices. This study suggests that the support of quantitative methods
such as spare part classification models and the use of simulation may be of great help to practitioners, in order to focus their effort on what really matters, to adopt cost-effective decisions and to assess the robustness of their decisions to varying exogenous conditions
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Which Democracies Pay Higher Wages?
No full textThis paper asks if and how constitutions affect labour market outcomes. This question is motivated by Rodrik (1999), who suggests that 'democracies pay higher wages' and Persson and Tabellini (2003) who provide evidence that constitutions impact on economic outcomes. An empirical analysis using treatment effect estimators and Bayesian Model Averaging provides robust causal evidence that presidential democracies are associated with lower wages, after controlling for other potential determinants such as the level of income per capita.Democracy, Constitutions, Wages, Factor Shares, Bayesian Model Averaging
The Ekström–Persson conjecture regarding random covering sets
No full textAbstract
We consider the Hausdorff dimension of random covering sets formed by balls with centres chosen independently at random according to an arbitrary Borel probability measure on ℝ𝑑 and radii given by a deterministic sequence tending to zero. We prove, for a certain parameter range, the conjecture by Ekström and Persson concerning the exact value of the dimension in the special case of radii (𝑛−𝛼)∞𝑛=1. For balls with an arbitrary sequence of radii, we find sharp bounds for the dimension and show that the natural extension of the Ekström–Persson conjecture is not true in this case. Finally, we construct examples demonstrating that there does not exist a dimension formula involving only the lower and upper local dimensions of the measure and a critical parameter determined by the sequence of radii.Abstract
