An indicator of pro-poorness of a growth profile associated with a distribution of income is a measure of the extent to which growth is biased towards the poor. This paper proposes a general approach to pro-poorness, called the progressive sequential averaging principle (PSA), relaxing the requirement of rank preservation due to growth. An endogenous benchmark for evaluating the growth of poor comes out naturally from this principle. A dominance relation on the basis of the above approach for a class of growth profiles is introduced through a simple device, called the PSA curve and its properties are examined in relation to the standard dominances in terms of the generalized Lorenz curve and the inverse generalized Lorenz curve. The paper concludes with an application to evaluate growth profiles experienced by the United States between 2001-2007 and 2007-2013. [less ▲]

Mutation analysis is a well-studied, fault-based testing technique. It requires testers to design tests based on a set of artificial defects. The defects help in performing testing activities by measuring the ratio that is revealed by the candidate tests. Unfortunately, applying mutation to real-world programs requires automated tools due to the vast number of defects involved. In such a case, the effectiveness of the method strongly depends on the peculiarities of the employed tools. Thus, when using automated tools, their implementation inadequacies can lead to inaccurate results. To deal with this issue, we cross-evaluate four mutation testing tools for Java, namely PIT, muJava, Major and the research version of PIT, PITRV, with respect to their fault-detection capabilities. We investigate the strengths of the tools based on: a) a set of real faults and b) manual analysis of the mutants they introduce. We find that there are large differences between the tools’ effectiveness and demonstrate that no tool is able to subsume the others. We also provide results indicating the application cost of the method. Overall, we find that PITRV achieves the best results. In particular, PITRV outperforms the other tools by finding 6% more faults than the other tools combined. [less ▲]

Although cohort and country differences in average cognitive levels are well established, identifying the degree and determinants of inequalities in old age cognitive functioning could guide public health and policymaking efforts. We use all publicly available and representative old age surveys with comparable information to assess inequalities of cognitive functioning in six distinctive age groups of 29 countries. We document that cognitive inequalities in old age are largely determined by earlier educational inequalities as well as gender differential survival rates. For example, a one percentage point increase in the Gini index of past education is associated with an increase of 0.45 percentage points in the Gini index of delayed recall and 0.23 percentage points in the Gini of immediate recall. Results are robust to a variety of alternative explanations and persist even after controlling for gender-related biases in survival rates. Furthermore, we find evidence that unequal opportunities for education -captured by differences in parental background and gender- also have significant effects on inequality of old age cognition.

Context. Metacognitive therapy and one of its treatment components, the attention training technique are increasingly being delivered to improve mental health. Objective. To examine the efficacy of metacognitive therapy and/or attention training technique on mental health outcomes from single-case studies. Methods. Fourteen studies (53 patients) were included. The d-statistic for multiple baseline data and the percentage change index were used to compute the effect sizes. Results. Metacognitive therapy has a large effect on depression, anxiety, other psychopathological symptoms, and all outcomes together. Effect sizes were significantly moderated by the number of sessions, the severity and duration of symptoms, and patient gender, but not by study quality or attention training technique when used as a stand-alone treatment. At the follow-up, 77.36% of the individuals were considered recovered or had maintained improvement. Conclusion. Metacognitive therapy and attention training technique strongly contribute to improving mental health outcomes. This study effectively informs evidence-based practice in the clinical milieu.

Background: Impulsivity is a multidimensional construct playing a pervasive role in psychiatry and neuropsychology. Lynam et al. (2006) have developed the 59-item UPPS-P Impulsive Behavior Scale, which assesses five distinct impulsivity dimensions: positive urgency, negative urgency, lack of perseverance, lack of premeditation, and sensation seeking. The short, 20-item version of the UPPS-P (SUPPS-P; Billieux et al. 2012) has been developed and adapted into several languages, including English, French, Italian, Spanish, and Arabic. The aim of the present study was to test four theoretical models of the SUPPS-P in a large sample of Hungarian adults. Methods: A total of 15,703 participants (64.76% male; Mage = 33.42 years, SD = 11.06) completed the SUPPS-P using an online questionnaire. Results: Confirmatory factor analyses corroborated the first-order five-factor model of impulsivity and a hierarchical model representing three higher-order constructs (urgency, lack of conscientiousness, sensation seeking), whereas the one-factor and three-factor model were not supported. The factor structure of the SUPPS-P preserved the original, theory-driven structure of the UPPS-P model and this instrument demonstrated good internal consistency. Hypersexual behavior consequences were positively associated with most SUPPS-P components, thus criterion validity was also supported. Conclusion: The SUPPS-P had strong psychometric properties that reflected the theoretical structure of the original UPPS-P model, thus it constitutes a theoretically grounded and time saving multidimensional instrument for assessing impulsivity.

Mutation testing is widely considered as a high-end test coverage criterion due to the vast number of mutants it generates. Although many efforts have been made to reduce the computational cost of mutation testing, in practice, the scalability issue remains. In this paper, we explore whether we can use compression techniques to improve the efficiency of strong mutation based on weak mutation information. Our investigation is centred around six mutation compression strategies that we have devised. More specifically, we adopt overlapped grouping and Formal Concept Analysis (FCA) to cluster mutants and test cases based on the reachability (code covergae) and necessity (weak mutation) conditions. Moreover, we leverage mutation knowledge (mutation locations and mutation operator types) during compression. To evaluate our method, we conducted a study on 20 open source Java projects using manually written tests. We also compare our method with pure random sampling and weak mutation. The overall results show that mutant compression techniques are a better choice than random sampling and weak mutation in practice: they can effectively speed up strong mutation 6.3 to 94.3 times with an accuracy of >90%.

As an introductory article of a Special Issue on Environmental and Sustainability Education (ESE) in the Benelux region, this paper provides an overview of ESE research, policy and practice in Belgium, The Netherlands and Luxembourg. It discusses the different contributions in this collection with regard to how the central theme of this issue, the relation between education and societal transformation, is approached in each paper. The main characteristics of the ESE research fields in the Benelux are described in general terms, and placed within the context of how ESE policy and practice are organised in these countries. Next, different conceptualisations of the relation between educational and political spaces reflected in the collection are discussed and the varied contributions to this issue are positioned in relation to three distinguished traditions of approaching the place of democracy in ESE. The authors conclude with commenting on how this relates to different approaches to the research-policy-practice interface. [less ▲]

This chapter explores how time and temporality – that is, the rhythms and tempos of social and environmental change – have been considered in social theory before going on to explore the conceptual frameworks and practices through which policy-makers seek to influence temporal processes in the specific context of climate change policy. The chapter highlights conflict between the temporalities of climate change and the temporalities of politics, as well as conflict between the temporalities of competing political and decision-making processes. While policy-makers advocate strategies to depoliticize climate policy in response to these conflicts, the chapter argues this is neither possible nor desirable. Instead, it advocates more democratic and deliberative approaches to the challenge of synchronizing ever more visible ecological temporalities with the multiple temporalities of the social. [less ▲]

New generation of free trade agreements (CETA, TTIP, agreements with Singapore, China, Vietnam, Japan i.e.) are the expression of the objective of making the European Union a global international actor. The external action of the Union is however dependent on the principle of conferral and the division of competences with its Member States. It results from Opinion 2/15 of the Court of Justice that the EU competence to conclude the free trade agreement with Singapore is not exclusive, as long as provisions concerning non-direct investments and dispute settlement fall under the shared competence of the Union and its Member States. The limits of the Union’s external competence and the conclusion of a mixed agreement jeopardise the effectiveness of the Union’s external action. However, the objective of an efficient external action allows a novel interpretation of the scope of the Union’s competence in the field of common commercial policy, comprising sustainable development provisions, as well as of the conditions of exercise of shared external competences.

A reliable and safety infrastructure for both transport and traffic is becoming increasingly important today. The condition assessment of bridges remains difficult and new methods must be found to provide reliable information. A meaningful in-situ assessment of bridges requires very detailed investigations which cannot be guaranteed by commonly used methods. It is known that the structural response to external loading is influenced by local damages. However, the detection of local damage depends on many factors such as environmental effects (e.g. temperature), construction layer (e.g. asphalt) and accuracy of the structural response measurement. Within the paper, a new so-called Deformation Area Difference (DAD) Method is presented. The DAD method is based on a load deflection experiment and does not require a reference measurement of initial condition. Therefore, the DAD method can be applied on existing bridges. Moreover, the DAD method uses the most modern technologies such as high precision measurement techniques and attempts to combine digital photogrammetry with drone applications. The DAD method uses information given in the curvature course from a theoretical model of the structure and compares it to real measurements. The paper shows results from a laboratory load-deflection experiment with a steel beam which has been gradually damaged at distinct positions. The load size is chosen so that the maximum deflection does not exceed the serviceability limit state. With the data obtained by the laboratory experiment, the damage degree, which can still be detected by the DAD method, is described. Furthermore, the influence of measurement accuracy on damage detection is discussed. [less ▲]

By and large, we take our universities for granted. Indeed, the oldest have outlived political regimes of all kinds. This stimulating historical and comparative study exemplifies the importance of in-depth experience and engagement with the cultural and structural environments in which some of the world’s greatest universities have over centuries incrementally developed and been embedded. This is crucial if we hope to understand the sources of their authority and myriad contributions to scientific knowledge and human flourishing. A neo-institutionalist scholar and multicultural citizen who fruitfully contributes to dialogues exploring core institutions in education and society on both sides of the Atlantic, Heinz-Dieter Meyer is uniquely placed to grapple with the complex processes of institutional learning and design that have made the German and American universities among the globally most productive. He also shows how they have influenced each other via the complex, yet crucial flows of inspired scholars and students carrying key idea(l)s with them for interpretation and application back home. The contributions of key actors, but also the outcomes of choices at critical junctures, such as the failure to establish a national state-funded university in the United States, take center stage in this engaging account of how the leaders of American universities adapted the German model, joining diverse concepts to design what has become the greatest uni-versity system in the world, yet one that remains nearly impossible to emulate due to the unique constellation of actors and institutional environment in which it developed. In eighteen chapters in four parts, The Design of the University: German, American, and “World Class” takes us from Göttingen and Berlin to Boston and to the world level as the scientific enterprise—and competition between scientists and the most crucial organizational form in which they conduct their experiments and make their arguments, the research university—becomes ever more global. Contributing to and inviting debate, Meyer’s main argument is that the American university has suc-ceeded based upon an institutional design—or, perhaps, a non-design—that on multiple levels facil-itates self-government and the identification of a niche within an extraordinarily large and differen-tiated higher education system. This is not a full-fledged historiographic treatment of a subject fa-vored by academics (permanently searching for reputational gains) and policymakers (as they in-creasingly launch research funding programs and evaluation systems to foster competition). Rather than a full-fledged sociology of science, this book creatively sketches the trajectories of German and American university development, emphasizing affinities as well as crucial differences, to ulti-mately argue that in fact “Humboldt’s most important ideas flourished in the American atmosphere of unrestricted institutional experimentation and vigorous self-government” (xiii). Interrogating what he calls the “design thinking” of eminent thinkers Adam Smith and Wilhelm von Humboldt, among others, Meyer traces the challenging, complex, and contingent learning processes in the adaptation of the German research university model to the American context, eventually becoming the most differentiated and “world-class” higher education system in the world. Asking about the reasons for the American university’s success, especially in comparison to the recent insti-tutional crisis of the German research university, albeit still extraordinarily productive, Meyer argues that this American meritocratic success story has institutional design (of self-government) at its heart. Enjoying the patronage of not one, but three major institutions—state, church, and market—the American university attained true autonomy and global preeminence through unparalleled wealth of patronage and an intricate system of checks and balances. In this line of argument, chart-ing the ascendancy from humble origins of what can hardly be called a system due its extraordinary diversity, Meyer concurs with David Labaree (2017), who’s A Perfect Mess [1] is a highly-suitable com-panion piece grounded in the history of American higher education. Contemporary architects of higher education policy globally, driven by the fantasy of “world class” labels, Meyer warns, have completely underestimated the “institutional, social, and political prerequisites that excellence in research and teaching require” (p. 4). Meyer begins his treatise, appropriately, in Göttingen, the site of Georgia Augusta University, where many leaders of American higher education, first and foremost Boston Brahmin George Ticknor, learned by doing, ensconced in a cosmopolitan center of learning and intellectual enlightenment. The blueprint included professionalized scholarship, the unification of research and teaching in seminars and lectures, freedom to choose among academic offerings, a vast library of scientific knowledge, and academic standing based on perpetual production of cutting-edge research judged by peers (p. 19). Instead of Adam Smith’s preferred instruments of competition, choice, and tuition-dependence, Wilhelm von Humboldt’s “design revolution” proposed “three unities” whose powerful integration could surpass the utilitarian logic prevalent then and now: “teaching and research; scien-tific discovery and moral formation (Bildung); scholarly autonomy and scholarly community” (p. 40). The book’s second part, on institutional learning, charts the institutional migration of the blueprint; the contested design options of Gymnasium, college, and graduate school (the latter ultimately the key to global preeminence); the lasting influence of Protestantism (here Meyer follows the arguments of Max Weber, Robert K. Merton, and Joseph Ben-David) and extraordinary educational philanthropy; the battle between those who would centralize, by establishing a national university, and those committed to local control; and finally the contrasting answers to the eternal question of vocational-ism—e.g., how should business be treated, as a sibling to medicine and law or as their distant cousin? The more education-enamored, democratically-inclined patrician elites of the American East Coast were, Meyer argues, radically different institution-builders than German scholars, French state nobility, or even Chinese mandarins: “No other class combined their respect for, and grand vision of, the civilizing role of learning with their economic resources and the realism needed to put their plans into practice” (p. 113). Building on philosophical and historical elaboration, the book’s third part on achieving self-government discusses the six American moves leading to institutional innovation. At organizational level, the German chair and institute give way to departments and discipline, the university presi-dent is no longer figurehead but chief executive, and independent boards of trustees, not govern-ment officials, have ultimate authority. The implications for individuals and organizations of these “design shifts” cannot be overstated. Anyone seeking to understand American higher education, with its phenomenal vertical and horizontal differentiation and on-going academic drift (“a snake-like procession” as David Riesman, to whom the book is dedicated, calls it), and its self-organized autonomy—supported by many philanthropists without the limiting control of a few state bureau-crats—will find this analysis illuminating. Embedded in civil society, “vigorous self-government is the historic design contribution of the American university” (p. 209)—and an achievement that must be guarded in an era in which university autonomy is at risk. In concluding, Meyer’s American opti-mistic and laudatory tone shifts back to Germanic critique and foreboding, identifying challenges and the contemporary struggles that threaten the unintentional masterpiece of institutional learning and diversity. Such justified hopes and fears must now give way to empirical studies of the extraor-dinary outputs in terms of scientific production and societal capabilities and well-being brought about by the continuous process of university Bildung—in Germany, the United States, and around the world.
