the converse of this statement is in general no longer true. The first part of this paper studies the relation between the weights of points and the size of a linear set, and introduces the concept of the geometric field of linearity of a linear set. This notion will allow us to show the main theorem, stating that for particular linear sets without points of weight 1, the converse of the above statement still holds as long as we take the geometric field of linearity into account.

Published: February 2022

AbstractSatisfaction with life is a self-reported measure of the quality of life that has become a critical societal indicator extensively used for the evaluation and comparison of a wide range of trends and policies. This study fuses five cross-sectional travel surveys conducted from 1992 to 2018 across various geographical locations in California. Using the fused sample, we develop generalized ordered logit models to examine the effects of demographic characteristics, travel-related attributes, general and transport-related attitudinal variables, and context-control variables on individuals’ self-reported measures of life satisfaction. We find that longer commute times, mobility limitations, and a tendency to see travel as a waste of time are negatively associated with life satisfaction. To enable the use of disparate cross-sectional survey data, we incorporate context-control variables into the models. We find that life satisfaction appears to be increasing as GDP per capita increases. Among employed people, the macro-scale unemployment rate positively influences their life satisfaction. Interestingly, all else equal, we find that online opinion panel respondents have lower life satisfaction relative to respondents from other sampling methods (mainly address-based sampling), a finding that should be considered in future research using these sampling methods. Overall, this study provides a unique look at life satisfaction within a transport context, while providing an example of fusing small-scale survey datasets to study longitudinal, domain-specific, influences on variables like subjective well-being.

Abstract
Purpose
Patient-reported outcome measures (PROMs) are valuable tools in evaluating the outcomes of surgical treatment health-related quality of life (HRQoL) of women with stress urinary incontinence (SUI) and may be incorporated into related clinical quality registries. The aim of this study was to assess the feasibility and acceptability of incorporating PROMs into the Australian Pelvic Floor Procedure Registry (APFPR).

Methods
Semi-structured qualitative interviews were conducted with women with SUI (N = 12) and their managing clinicians (N = 11) in Victoria, Australia. Interview topics covered content and face validity, appropriateness, and acceptability of three incontinence-specific, two pain, one anxiety and depression, one sexual function and one patient global impression of improvement instruments identified through the literature to determine their suitability and acceptability for the APFPR. We analysed interview data into topics using conventional content analysis.

Results
Study participants agreed that PROMs were needed for the APFPR. Both participant groups suggested that some of the instruments were ambiguous, therefore only three instruments (one incontinence-specific, sexual function and patient global impression of improvement) will be included in the APFPR. Both clinicians and women agreed it would be appropriate to answer PROMs at baseline and then at 6- and 12-month postsurgically. Email, phone call and mail-out of the instruments were the preferred options for administration.

Conclusion
Most women and clinicians supported the feasibility of incorporating PROMs in the APFPR. Participants believed the PROMs would demonstrate useful aggregate HRQoL data and have potential for use in individual care.
Identification of the best medium for experiments on chemical computation with Belousov–Zhabotinsky reaction and ferroin-loaded Dowex beads

Published: February 2022

AbstractOur study is focused on identification of the best medium for future experiments on information processing with Belousov–Zhabotinsky reaction proceeding in Dowex beads with immobilized catalyst inside. The optimum medium should be characterized by long and stable nonlinear behavior, mechanical stability and should allow for control with electric potential. We considered different types of Dowex ion-exchange resins, bead distributions and various initial concentrations of substrates: malonic acid and 1,4-cyclohexanedione. The electric potential on platinum electrodes, stabilized by a potentiostat is used to control medium evolution. A negative electric potential generates activator species HBrO2 on the working electrode according to the reaction: BrO3−  + 2e−  + 3H+  → HBrO2 + H2O, while positive electric potential attracts inhibitor species Br− to the proximity of it. We study oscillation amplitude and period stability in systems with ferroin loaded Dowex 50W-X2 and Dowex 50W-X8 beads during experiments exceeding 16 h. It has been observed, that the above mentioned resins generate a smaller number of CO2 bubbles close to the beads than Dowex 50W-X4, which makes Dowex 50W-X2 and Dowex 50W-X8 more suitable for applications in chemical computing. We report amplitude stability, oscillation frequency, merging and annihilation of travelling waves in a lattice of Dowex 50W-X8 beads (mesh size 50–100) in over 19 h long experiments with equimolar solution of malonic acid and 1,4-cyclohexanedione. This system looks as a promising candidate for chemical computing devices that can operate for a day.
Spatial Structure of Youth Migration in Indonesia: Does Education Matter?
Authors: Malamassam Meirina Ayumi 
Published: February 2022

AbstractIt is broadly understood that migration works in a selective way, particularly by age and education. However, little is known about the variation of the spatial structures of migration by educational background. Using migration data from Indonesia’s 2000 and 2010 population censuses, this study examined the education-specific youth migration flows in Indonesia by highlighting interactions between origin and destination regions and examining factors contributing to the migration structure. Strong interactions were found amongst regions located in the same island or in close geographic proximity for all education levels. More dispersed patterns of origin–destination pairs were observed in tertiary-educated migration structure. The effects of economic opportunities appear to have had more pronounced effect in the migration structure of the least educated group. The findings highlight the increasing importance of rural areas in highly educated migration flows and the greater attractiveness of more developed regions for the lower educated migration structure. The spatial structures of education-specific youth migration flows reinforce the wide inequality gap in education and employment opportunities across regions in Indonesia.

AbstractGovernments worldwide have imposed lockdowns in their countries to restrict unnecessary movement and curb the spread and transmission of the Covid-19 as a mitigation measure. The education sector has also implemented rapid changes, and this has transformed the operational procedures for both students and lecturers. As the pandemic has progressed, its emotional and psychological toll is equally bearing on students, leading to lockdown fatigue. This study aimed to investigate the level of lockdown-induced fatigue and its correlation with personal resilience and coping skills among university students in Iraq. This study used quantitative methods of research using a cross-sectional study design. A questionnaire survey was distributed electronically among 819 university students in Iraq. The study used three standardised scales: the lockdown fatigue scale, brief resilience scale, and coping behaviours questionnaire for data collection. Descriptive and inferential statistical analysis were done using SPSS. Overall, students indicated a high level of lockdown fatigue with a mean score of 33.48out of 50. Fear of personal safety and the wellbeing of the family was the most fear expressed by the students. The ability to go through stressful times and unpleasant events was the most common worry among the students. Female, urbanised, and science field students were the most students who suffered from lockdown-induced fatigue. However, positive coping behaviours and personal resilience were significantly correlated with decreasing fatigue levels during the lockdown period. Level of lockdown fatigue accelerated in an alarming stage among university students in Iraq. Hence, students need to build their emotional resilience and learn how to navigate surviving hard times and bounce back after a loss. This could be facilitated by counselling services being availed to educational and social institutions to benefit university students.

Abstract
Neolithisation was a relatively fast process that affected both the interior and coastal zones of the Iberian Peninsula, but it was also a heterogeneous process that had diverse impacts on genomic and cultural diversity. In the Late Neolithic–Chalcolithic, a change in funerary practices, cultural material and trade networks occurred, and genomic heterogeneity decreased, suggesting human mobility and genetic admixture between different Iberian populations. Dental morphology has emerged as an effective tool for understanding genomic variability and biological affinities among ancient human populations. But, surprisingly, less attention has been paid to the morphological traits of inner dental tissues in Holocene European populations and their utility for the study of population dynamics. We applied 3D geometric morphometric methods on the enamel-dentine junction (EDJ) of the first upper molars to explore the biological affinities of north-eastern Iberian Peninsula populations from the Late Neolithic–Chalcolithic to the Bronze Age. Our results show that the EDJ morphologies of the northern Iberian Peninsula populations were generally homogeneous, indicative of genetic admixture as a result of human mobility and exchange networks. However, differences in the EDJ traits in remains from the Can Sadurní site are indicative of distant biological affinities with nearby populations. Additionally, the hypocone associated dentine area and the position of the trigon dentine horns relative to each other on the occlusal surface best describe the variability found among the samples studied. This study highlights the utility of EDJ morphology as a genetic proxy in Holocene population dynamic studies when paleogenomic studies are absent.
“Too big to fail”: the resilience and entrenchment of food aid through food banks in the Netherlands during the COVID-19 pandemic

Published: February 2022

AbstractThis paper aims to better understand the resilience and further entrenchment of food aid through food banks in the context of the COVID-19 pandemic. During the first months of the pandemic in the Netherlands, concerns quickly rose about the number of people falling into conditions of food insecurity. Adding insult to injury, food banks reported problems in their operations. The analysis shows that after some adaptations to initial problems, food banks were largely able to continue their service. This ability was partly based on organizational flexibility. However, in order to understand the resilience of food aid through food banks, it is imperative to understand food banks as part of a system of food aid that extends beyond the organizational boundaries. This system includes a range of other actors and resources, including donors, public support and governmental backing that contributed to the resilience of the food aid system. While this embeddedness in a system as well as broad public support were essential for the resilience of food aid through food banks, both factors also indicate the further entrenchment of food banks in the understanding and practices of ensuring food security for people in poverty. Ultimately, when the root causes of a need for food aid are not addressed, a resilient system of food aid through food banks can eventually prove detrimental to societal resilience, specifically the ability to ensure dignified access to adequate food.
Dual inhibition of anti-apoptotic proteins BCL-XL and MCL-1 enhances cytotoxicity of Nasopharyngeal carcinoma cells

Published: February 2022

AbstractOne of the many strategies that cancer cells evade death is through up-regulation of the BCL-2 anti-apoptotic proteins. Hence, these proteins have become attractive therapeutic targets. Given that different cell populations rely on different anti-apoptotic proteins for survival, it is crucial to determine which proteins are important for Nasopharyngeal carcinoma (NPC) cell survival. Here we determined the survival requirements for the NPC cells using a combination of the CRISPR/Cas9 technique and selective BH3-mimetics. A human apoptosis RT2 Profiler PCR Array was first employed to profile the anti-apoptotic gene expressions in NPC cell lines HK-1 and C666-1. The HK-1 cells expressed all the anti-apoptotic genes (MCL-1, BFL-1, BCL-2, BCL-XL, and BCL-w). Similarly, the C666-1 cells expressed all the anti-apoptotic genes except BFL-1 (undetectable level). Notably, both cell lines highly expressed MCL-1. Deletion of MCL-1 sensitized the NPC cells to BCL-XL selective inhibitor A-1331852, suggesting that MCL-1 and BCL-XL may be important for NPC cell survival. Co-inhibition of MCL-1 and BCL-2 with MCL-1 selective inhibitor S63845 and BCL-2 selective inhibitor ABT-199 inhibited NPC cell proliferation but the effect on cell viability was more profound with co-inhibition of MCL-1 and BCL-XL with S63845 and A-1331852, implying that MCL-1 and BCL-XL are crucial for NPC cell survival. Furthermore, co-inhibition of MCL-1 and BCL-XL inhibited the growth and invasion of NPC spheroids. Deletion of BFL-1 sensitized NPC cells to A-1331852 suggesting that BFL-1 may play a role in NPC cell survival. Taken together co-inhibition of BCL-XL and MCL-1/BFL-1 could be potential treatment strategies for NPC.
Data quality, experimental artifacts, and the reactivity of the psychological subject matter
Authors: Feest Uljana 
Published: February 2022

AbstractWhile the term “reactivity” has come to be associated with specific phenomena in the social sciences, having to do with subjects’ awareness of being studied, this paper takes a broader stance on this concept. I argue that reactivity is a ubiquitous feature of the psychological subject matter and that this fact is a precondition of experimental research, while also posing potential problems for the experimenter. The latter are connected to the worry about distorted data and experimental artifacts. But what are experimental artifacts and what is the most productive way of dealing with them? In this paper, I approach these questions by exploring the ways in which experimenters in psychology simultaneously exploit and suppress the reactivity of their subject matter in order to produce experimental data that speak to the question or subject matter at hand. Highlighting the artificiality of experimental data, I raise (and answer) the question of what distinguishes a genuine experimental result from an experimental artifact. My analysis construes experimental results as the outcomes of inferences from the data that take material background assumptions as auxiliary premises. Artifacts occur when one or more of these background assumptions are false, such that the data do not reliably serve the purposes they were generated for. I conclude by laying out the ways in which my analysis of data quality is relevant to, and informed by, recent debates about the replicability of experimental results.

Published: February 2022

AbstractIn oil and gas industry, sand can be carried with oil and gas, when producing from unconsolidated sandstone reservoirs. The existence of sand particles with fluids flow can lead to severe damages to production system’s components. Therefore, sand control techniques are needed to prevent potential damages. Standalone sand screens (SAS) are widely used because they can provide reliable sand control with low cost and low complexity. However, SAS application can become disadvantageous because of mechanical erosion due to sand particle impingement. The experimental investigation of sand screens erosion is challenging, as the measurements are to be carried out for a representative SAS material and geometry at laboratory-scale simulated conditions. The simulated conditions should mimic the real flow conditions, which involve many interrelated parameters. Some of these parameters are related to the entrained sand particles (i.e., particle shape, size and, concentration) while other parameters are related to the flow characteristics (i.e., flow velocity and fluid properties). In this review, the key factors influencing sand screens erosion are described, and erosion mechanisms are highlighted. In addition, experimental results showing the effects of key parameters on SAS erosion are discussed and evaluated. Also, challenges associated with previous studies, along with a proposed outlook to overcome those challenges, are presented. It has been found that the limitations of the previous studies are related to test setup and flow direction, particle–particle interaction, and particle–fluid interaction considerations. This review highlighted noticeable research gaps in sand screens erosion measurements that can be considered in future.
An overview of sociotechnical research on maritime energy efficiency
Authors: Viktorelius Martin , Varvne Hanna , von Knorring Hannes 
Published: February 2022

Abstract
A qualitative synthesis is presented covering the literature on operational energy efficiency in shipping based on research from a sociotechnical perspective. Three themes were identified, using thematic analysis, as particularly significant for the management of energy: (i) cooperation, communication, and knowledge sharing between stakeholders; (ii) organizational information processing (cognitive bottlenecks and sense making practices); and (iii) professional education and training. We conclude that while previous research has uncovered many of the barriers to increasing energy efficiency, few studies have examined the interdependence of practices and technologies underlying organizational cognitive systems and change. The identified research gap calls for more longitudinal process-based case studies investigating the design, implementation, and use of information technologies supporting organizational planning and decision-making required for improving energy efficiency.
Does Regular Physical Activity Mitigate the Age-Associated Decline in Pulmonary Function?

Published: February 2022

AbstractWhereas the negative effects of aging and smoking on pulmonary function are undisputed, the potential favorable effects of physical activity on the aging process of the otherwise healthy lung remain controversial. This question is of particular clinical relevance when reduced pulmonary function compromises aerobic exercise capacity (maximal oxygen consumption) and thus contributes to an increased risk of morbidity and mortality. Here, we discuss whether and when the aging-related decline in pulmonary function limits maximal oxygen consumption and whether, how, and to what extent regular physical activity can slow down this aging process and preserve pulmonary function and maximal oxygen consumption. Age-dependent effects of reduced pulmonary function (i.e., FEV1, the volume that has been exhaled after the first second of forced expiration) on maximal oxygen consumption have been observed in several cross-sectional and longitudinal studies. Complex interactions between aging-related cellular and molecular processes affecting the lung, and structural and functional deterioration of the cardiovascular and respiratory systems account for the concomitant decline in pulmonary function and maximal oxygen consumption. Consequently, if long-term regular physical activity mitigates some of the aging-related decline in pulmonary function (i.e., FEV1 decline), this could also prevent a steep fall in maximal oxygen consumption. In contrast to earlier research findings, recent large-scale longitudinal studies provide growing evidence for the beneficial effects of physical activity on FEV1. Although further confirmation of those effects is required, these findings provide powerful arguments to start and/or maintain regular physical activity.
