We study the maximum degree in such graphs in a growing observation window and show that its limiting distribution is Frechet. We achieve this by proving convergence of the underlying point process of the degrees to a certain Poisson process. Estimating the index of the power-law tail for the typical degree distribution is an important question in statistics. We prove consistency of the Hill estimator for the inverse of the tail exponent of the typical degree distribution.

In this pictorial, we unravel the design process of Asynja, an artefact that triggers exercise imagery by using natural scents related to running. Relying on peripheral interaction, this research probe subtly nudges users to go running, thereby supporting them to transform their positive intentions into actions. Exploring sensoriality as a design opportunity for behavior change interventions, we invite the community to expand the design space of exercise-related motivational products and systems.

[more ▼]The psychological needs-driven UX approach is a well-explored area in UX research and a powerful framework for the design of optimal experiences with systems and products. However, the transfer from research to practice is slow and this approach is not yet widely used by practitioners. As card- based methods have been shown to support designers in both the generation of ideas and the evaluation of their designs, we created the UX needs cards as a pragmatic tool able to support a needs-driven UX process. We present the iterative development of the card-set and its associated techniques and report on three use cases, demonstrating the effectiveness of this tool for user research, idea generation and UX evaluation. Our empirical findings suggest that the UX needs cards are a valuable tool able to support design practice, being easily understood by lay users and a source of inspiration for designers. Acting as a tangible translation of a research framework, the UX needs cards promote theory-driven design strategies and provide researchers, designers, and educators with a tool to clearly communicate the framework of psychological needs.

[more ▼]Aware of the consequences of their inactive lifestyles, many people still struggle to integrate enough physical activity into their busy lives. Interventions that nudge to reinforce existing active behavior seem therefore more likely to be effective than those adding an activity to daily routines. To encourage people to increase their physical activity level, we designed Discov, a network of physical waypoints triggering people to lengthen their walks. Placed in a public park, Discov encourages people to explore their surroundings in a fun and challenging way by creating an interactive walking experience. Adopting a Research-through-Design approach, we explore the potential of the design of accessible infrastructures and human-environment interactions to impact public health by nudging citizens into being more physically active. We discuss insights gathered through this process and report on first user tests of this interactive walking experience.

[more ▼]We consider a two-echelon spare parts inventory system consisting of one central warehouse and multiple local warehouses. Each warehouse keeps multiple types of repairable parts to maintain several types of capital goods. The local warehouses face Poisson demand and are replenished by the central warehouse. We assume that unsatisfied demand is backordered at all warehouses. Furthermore, we assume deterministic lead times for the replenishments of the local warehouses. The repair shop at the central warehouse has two repair options for each repairable part: a regular repair option and an expedited repair option. Both repair options have stochastic lead times. Irrespective of the repair option, each repairable part uses a certain resource for its repair. Assuming a dual-index policy at the central warehouse and base stock control at the local warehouses, an exact and efficient evaluation procedure for a given control policy is formulated. To find an optimal control policy, we look at the minimization of total investment costs under constraints on both the aggregate mean number of backorders per capital good type and the aggregate mean fraction of repairs that are expedited per repair resource. For this non-linear non-convex integer programming problem, we develop a greedy heuristic and an algorithm based on decomposition and column generation. Both solution approaches perform very well with average optimality gaps of 1.56 and 0.23 percent, respectively, across a large test bed of industrial size. Based on a case study at Netherlands Railways, we show how managers can significantly reduce the investment in repairable spare parts when dynamic repair policies are leveraged to prioritize repair of parts whose inventory is critically low.

[more ▼]Les établissements publics ont besoin de faire preuve d’agilité organisationnelle pour être performants et répondre aux nouveaux enjeux sociétaux. Cependant, ce besoin d’agilité est freiné par la logique bureaucratique qui sous-tend le fonctionnement-même de ces établissements. Résoudre cette tension paradoxale entre bureaucratie et agilité organisationnelle requiert de mettre en œuvre le processus d’acceptation et de management de la tension paradoxale. Pour ce faire, la communauté de pratique pilotée offre un cadre d’analyse favorisant cette acceptation et donc le changement organisationnel souhaité. Ainsi, nous montrons, au travers d’une recherche action, comment la communauté de pratiques pilotée favorise le changement organisationnel au sein d’un établissement public luxembourgeois en facilitant sa transition d’une logique bureaucratique vers une logique d’agilité organisationnelle. Les implications sont doubles. Premièrement, nous montrons comment manager la tension entre bureaucratie et agilité au sein d’un établissement public. Deuxièmement, nous mettons en lumière le rôle de la communauté de pratique pilotée comme vecteur de changement organisationnel d’un établissement public.

[more ▼]Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.

Their connections with generalized weighted quasi-geometric means is presented. It is shown that invariance\ question within the class of this operations leads to means of iterative type and to a problem on a composite functional equation. An application of the invariance identity to determine effectively the limit of the sequence of iterates of some generalized quasi-geometric mean-type mapping, and the form of all continuous functions which are invariant with respect to this mapping are given. The equality of two considered operations is also discussed.

[more ▼]Today, higher education is typically seen as offering the most assured pathways to secure careers and low unemployment rates. Yet, increasingly some groups, not least higher education graduates and their families paying ever-higher tuition fees, question the taken-for-granted contributions higher education makes to individuals and society as a whole. Despite decades of mass higher education expansion, even societies with strong systems continue to struggle to achieve their goal of universalizing participation and equalizing access. While in part this is due to limited public or corporate funding for (affordable) study opportunities, differentiated systems, such as in the US, also lack policy coordination and effective governance, providing a surfeit of options. While participation rates have climbed worldwide, higher education systems continue to produce winners (“insiders”) and losers (“outsiders”), even as the “schooled society” shifts the occupational structure upward. Market-oriented higher education systems face increasing privatization, which also involves financializing university governance. Many states have retrenched investments that had once underwritten universities’ flourishing and their moves toward massification. Tensions have deepened over who should pay for rising costs, exacerbated in an era of increasing status competition via higher education. In the face of such challenges globally, which alternatives exist? A prominent possibility, pioneered in Germany in the 1970s, are “dual study” programs offered by several organizational forms, from vocational academies to universities of applied sciences. Such hybrid programs fully integrate phases of higher education study and paid work in firms. Another potential advantage of apprenticeship training being offered in conjunction with higher education is that this would boost the reputation of apprenticeships overall. The German experience indicates that the attractiveness of the apprenticeship training system as a whole can be bolstered when it offers a viable pathway also for those individuals with a traditional university entrance certificate. If these students seriously consider and choose advanced work-based higher education, this may well increase the standing of apprenticeship training among students, their families, and employers. Thus, dual study programs provide an innovative model for policymaking and implementation. Especially when considering strategies to improve skill formation overall, to reduce the costs individuals must bear in attaining higher education, and to improve the fit between the expectations of employers and potential employees regarding skill formation, dual study programs excel. The origins and contemporary developments in work-based higher education in Germany offer lessons and inspiration for Anglophone countries, with their strong and differentiated higher education systems, to further bolster study programs coordinated with firms.

[more ▼]Co-authored research articles in the disciplinarily heterogeneous field of higher education have dramatically increased in this century, largely driven, as in other fields, by rising international co-authorships. We examine this evolving international collaboration network in higher education research over two decades. To do so, we apply automated bibliometric topic identification and social network analysis of 9,067 papers in 13 core higher education journals (1998–2018). Remarkable expansion in the volume of papers and co-authorships has, surprisingly, not resulted in a more diverse network. Rather, existing co-authorship patterns are strengthened, with the dominance of scholars from a few Anglophone countries largely maintained. Researchers globally seek to co-author with leading scholars in these countries, especially the US, UK, and Australia—at least when publishing in the leading general HE journals based there. Further, the two-mode social network analysis of countries and topics suggests that while Anglophone countries have led the development of higher education research, China and Germany, as leading research-producing countries, are increasingly influential within this world-spanning network. Topically, the vast majority of co-authored papers in higher education research focuses on individual-level phenomena, with organizational and system-level or country-level analysis constituting a (much) smaller proportion, despite policymakers’ emphasis on cross-national comparisons and the growing importance of university actorhood. We discuss implications thereof for the future of the multidisciplinary higher education field.

[more ▼]Machine learning (ML) advances have been extensively explored for implementing large-scale malware detection. When reported in the literature, performance evaluation of ML-based detectors generally focuses on highlighting the ratio of samples that are correctly or incorrectly classified, overlooking essential questions on why/how the learned models can be demonstrated as reliable. In the Android ecosystem, several recent studies have highlighted how evaluation setups can carry biases related to datasets or evaluation methodologies. Nevertheless, there is little work attempting to dissect the produced model to provide some understanding of its intrinsic characteristics. In this work, we fill this gap by performing a comprehensive analysis of a state-of-the-art Android Malware detector, namely DREBIN, which constitutes today a key reference in the literature. Our study mainly targets an in-depth understanding of the classifier characteristics in terms of (1) which features actually matter among the hundreds of thousands that DREBIN extracts, (2) whether the high scores of the classifier are dependent on the dataset age, (3) whether DREBIN's explanations are consistent within malware families, etc. Overall, our tentative analysis provides insights into the discriminatory power of the feature set used by DREBIN to detect malware. We expect our findings to bring about a systematisation of knowledge for the community.

In this paper we investigate this concept through a number of examples based on certain geometrical constructions. In particular, our study shows to which extent the computation of the best constant associated with an n-distance may sometimes be difficult and tricky. It also reveals that two important graph theoretical concepts, namely the total length of the Euclidean Steiner tree and the total length of the minimal spanning tree constructed on n points, are instances of n-distances.

[more ▼]Student motivation and affect play an important role in successful language learning. To investigate the formation of language learning motivation and affect, this study extended the generalized internal/external frame of reference (GI/E) model framework to multiple languages (German and French, along with math) and multiple motivational-affective outcomes (academic self-concept, interest, and anxiety). We examined whether social and dimensional comparisons play similar roles in the formation of students’ self-concepts, interests, and anxieties concerning different languages and whether dimensional comparisons result in contrast or assimilation effects. Moreover, we tested the generalizability of the GI/E model assumptions across students with different language backgrounds. Using a data set comprising virtually all ninth-grade students (N=6275; 48.0% female) from Luxembourg’s multilingual educational system, our findings indicated (1) clear contrast effects in the formation of self-concept and interest in math, German, and French, and (2) a combination of contrast, assimilation, and no effects in the formation of anxiety in math, German, and French. Using a subsample of 5837 students with valid language information (48.0% female), invariance tests demonstrated that the GI/E achievement–outcome relations operated equivalently across students from different home language backgrounds.
