This paper focuses on a conversation with Dr. Kenneth Tobin, which took place in June 2009 at The Graduate Center of the City University of New York (CUNY), where he is Presidential Professor in the Urban Education Program. Our purpose was to focus on Ken’s career in science education, and to discuss the past, present, and future of his research interests. During our conversation, we explored the various trajectories of his career, focusing on the ways in which his research has evolved through the years. Further, Ken shared his thoughts on the field of science education, and provided salient advice for early career scholars. This manuscript includes an introductory summary of Ken’s career achievements to this point, a record of our conversation (the audio-recording can be downloaded at the journal’s website) and a list of selected publications that highlight Ken’s key works.

The 2017 Dagstuhl Seminar on Computational Proteomics provided an opportunity for a broad discussion on the current state and future directions of the generation and use of peptide tandem mass spectrometry spectral libraries. Their use in proteomics is growing slowly, but there are multiple challenges in the field that must be addressed to further increase the adoption of spectral libraries and related techniques. The primary bottlenecks are the paucity of high quality and comprehensive libraries and the general difficulty of adopting spectral library searching into existing workflows. There are several existing spectral library formats, but none capture a satisfactory level of metadata; therefore a logical next improvement is to design a more advanced, Proteomics Standards Initiative-approved spectral library format that can encode all of the desired metadata. The group discussed a series of metadata requirements organized into three designations of completeness or quality, tentatively dubbed bronze, silver, and gold. The metadata can be organized at four different levels of granularity: at the collection (library) level, at the individual entry (peptide ion) level, at the peak (fragment ion) level, and at the peak annotation level. Strategies for encoding mass modifications in a consistent manner and the requirement for encoding high-quality and commonly-seen but as-yet-unidentified spectra were discussed. The group also discussed related topics, including strategies for comparing two spectra, techniques for generating representative spectra for a library, approaches for selection of optimal signature ions for targeted workflows, and issues surrounding the merging of two or more libraries into one. We present here a review of this field and the challenges that the community must address in order to accelerate the adoption of spectral libraries in routine analysis of proteomics datasets.

We study the free expansion of a dilute two-component Fermi gas with attractive interspecies interaction in the BCS-BEC crossover. We apply a time-dependent parameter-free density-functional theory by using two choices of the equation of state: an analytic formula based on Monte Carlo data and the mean-field equation of state resulting from the extended BCS equations. The calculated axial and transverse radii and the aspect ratio of the expanding cloud are compared to experimental data on vapors of 6 Li atoms. Remarkably, the mean-field theory shows a better agreement with the experiments than the theory based on the Monte Carlo equation of state. Both theories predict a measurable dependence of the aspect ratio on expansion time and on scattering length. [less ▲]

As first generation immigrants are currently approaching retirement age in many European countries, intergenerational solidarity within the context of acculturation gains high importance. However, most research on intergenerational relations in ageing families so far has not drawn special attention to migrant families. The aim of the present study was to investigate similarities and differences in the expectations about intergenerational support in a sample of n = 48 Luxembourgish (68.8% female) and n = 36 Portuguese (60.5% female) adult children and at least one of their parents. Luxembourgish adult children were on average M = 25.90 (SD = 5.74) years old, Portuguese M = 27.28 (SD = 6.49). A total of 58.3% of Portuguese adult children were born in Luxembourg; the remainder was born in Portugal but had grown up in Luxembourg. For all participants, both parents were still alive and were living in the Grand-Duchy. Whereas Luxembourgish and Portuguese adult children did not differ regarding family cohesion and expected support from parents toward children, Portuguese participants reported higher expectations of support from adult children toward their ageing parents. More Portuguese than Luxembourgish parents indicated they would like to live with their children in case of need, whereas more Luxembourgish parents preferred to live in a residential home. Nonetheless, no differences between adult children of both national groups were found regarding filial anxiety about future care of parents. Results are discussed in the framework of an integrative model on intergenerational family relations in the light of migration and ageing. This model takes several aspects into account that might have an impact on different needs, tasks and resources of the individual and the family depending on different family cultures, the larger cultural context in which family relations are embedded as well as significant events over the life-span (such as migration history).

A main mechanism behind the change in European and North American societies in the second half of the 20th century is the educational expansion, i.e. the increase in educational opportunities and the higher demand for education. Whereas other abstract social processes like modernization have been widely theorized in social science literature, the educational expansion and its consequences in particular have not been well studied. Therefore the main aim of this compilation is to deal with the question of whether the demands of the educational reforms have been fulfilled and which other consequences the educational expansion has had. This book will focus on consequences of the educational expansion for individuals and their life courses as well as for the social structure and other societal areas such as culture and politics. Aspects that will be analysed in the light of educational expansion include participation in education, educational inequalities, labour market outcomes, educational returns, and gender differences as well as crime, life expectancy, and lifestyles. Countries analysed in the book include West European countries like Germany, France, Italy and Spain, East European countries (Hungary, Poland, and the Czech Republic) as well as the US. [less ▲]

This paper proposes a theoretical and experimental analysis of the expected running time for an elitist parallel Evolutionary Algorithm (pEA) based on an island model executed over small-world networks. Our study assumes the resolution of optimization problems based on unimodal pseudo-boolean funtions. In particular, for such function with d values, we improve the previous asymptotic upper bound for the expected parallel running time from O(d√n) to O(d log n). This study is a first step towards the analysis of influence of more complex network topologies (like random graphs created by P2P networks) on the runtime of pEAs. A concrete implementation of the analysed algorithm have been performed on top of the ParadisEO framework and run on the HPC platform of the University of Luxembourg (UL). Our experiments confirm the expected speed- up demonstrated in this article and prove the benefit that pEA can gain from a small-world network topology. [less ▲]

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.

The experience of visiting museums has evolved to extend beyond the walls of the institutions themselves into digital spaces, where online galleries, exhibitions, and virtual tours invite audiences to explore arts and culture from their personal devices. However, generating interest from the public around these platforms remains a challenge, and the digital experience rarely compares to an in-person visit. Building on research that demonstrates the effectiveness of emotional design as a way to generate public engagement with physical museum spaces and exhibitions, this project adopts a user-centered design approach to develop novel experiences around digitized museum collections.

With the growing importance of digital technologies in learning and assessment, it is important to consider user experience (UX) to ensure that tools provide useful functionalities for learning without overwhelming users, to motivate users and ensure that they have positive learning experiences, and to allow users to realize their potential with the help of technology. Building on a case study of concept mapping for technology-enhanced learning, we combined experience-driven and functionality-driven approaches in co-design sessions in four school classes (67 students). We investigated the anticipated experiences that students imagined as well as the functionalities and characteristics they expected. We found that combining experience-driven and functionality-driven approaches is a valuable method for improving technology-enhanced learning. [less ▲]

This chapter contrasts two different views on ageing. An external “view from without” starts in a first step with the description of phenomena associated with human ageing including the notions of death and dying. This is followed by presenting an overview of central and mostly psychological models and theories about human ageing. Here, life span conceptions as well as theories on self-regulation of the ageing self are described and discussed. Furthermore, a specific focus is put on the differing qualifications that the term ageing has received in diverse theoretical models. The internal “view from within” finally starts with three case stories presenting excerpts of individual biographic narratives that highlight the importance of life events and adaptive processes within the family in the subjective construction of the self and the life course. The conclusion elaborates a person-centred approach in the study of human ageing taking into account that both family and culture interact in forming development in general as well as life in advancing age in particular.

Patients with chronic pain often report their cognition to be impaired by pain, and this observation has been supported by numerous studies measuring the effects of pain on cognitive task performance. Furthermore, cognitive intrusion by pain has been identified as one of 3 components of pain anxiety, alongside general distress and fear of pain. Although cognitive intrusion is a critical characteristic of pain, no specific measure designed to capture its effects exists. In 3 studies, we describe the initial development and validation of a new measure of pain interruption: the Experience of Cognitive Intrusion of Pain (ECIP) scale. In study 1, the ECIP scale was administered to a general population sample to assess its structure and construct validity. In study 2, the factor structure of the ECIP scale was confirmed in a large general population sample experiencing no pain, acute pain, or chronic pain. In study 3, we examined the predictive value of the ECIP scale in pain-related disability in fibromyalgia patients. The ECIP scale scores followed a normal distribution with good variance in a general population sample. The scale had high internal reliability and a clear 1-component structure. It differentiated between chronic pain and control groups, and it was a significant predictor of pain-related disability over and above pain intensity. Repairing attentional interruption from pain may become a novel target for pain management interventions, both pharmacologic and nonpharmacologic. [less ▲]
