AbstractEfficacy of the sol–gel derived Ni-doped Mg-ferrites for an enhanced CO2 splitting activity is investigated. The results allied with the characterization indicate the formation of nominally phase pure Ni-doped Mg-ferrites with a coarser particle morphology. Ni-doped Mg-ferrites are further tested for multiple thermal reduction as well as CO2 splitting steps by using a thermogravimetric analyzer. The results associated with the thermogravimetric analysis confirmed that most of the Ni-doped Mg-ferrites attained a steady TR aptitude after crossing the 5th or 6th cycle. Likewise, the CS capability of all the Ni-doped Mg-ferrites accomplished consistency after 4th cycle (except for Ni0.11Mg0.88Fe2.01O4.005). The Ni0.90Mg0.11Fe2.04O4.070 showed the highest amount of O2 release (117.1 μmol/g cycle) and CO production (210.3 μmol/g cycle) in ten consecutive thermochemical cycles. Besides, Ni0.29Mg0.72Fe1.98O3.980 indicated better re-oxidation aptitude ($$ n_{\text{CO}} /n_{{{\text{O}}_{2} }} $$nCO/nO2 ratio = 1.89) when compared with other Ni-doped Mg-ferrites.
The Bigger the Better? Business Size and Small-Business Owners’ Subjective Well-Being
Authors: Fors Connolly Filip , Johansson Sevä Ingemar , Gärling Tommy 
Published: May 2020

AbstractBusiness growth is often portrayed as an important outcome for small-business owners. Few empirical studies have however examined whether there is a positive relationship between business size and different dimensions of small-business owners’ subjective well-being. In a large cross-sectional sample (n = 1089) of small-business owners from Sweden, we investigate the relationship between business size and the two main components of subjective well-being, life satisfaction and emotional well-being. By means of structural equation modelling, we determine the importance of business size for subjective well-being by focusing on potential advantages (financial satisfaction) and disadvantages (time pressure) related to business size. The results show that there is no overall relationship between business size and life satisfaction, but a weak negative relationship between business size and emotional well-being. However, in a subsequent mediation analyses we find that these findings largely can be explained by the fact that financial satisfaction and time pressure relate to subjective well-being in opposite directions and thus cancel each other out. The results of the mediation analysis also reveal differences across the two components of subjective well-being. We here find that financial satisfaction is more important for small-business owners’ life satisfaction while time pressure is more important for their emotional well-being.

AbstractThe interest on applying mesenchymal stromal cells (MSCs) in orthopedic disorders has risen tremendously in the last years due to scientific successes in preclinical in vitro and animal model studies. In a wide range of diseases and injuries of the musculoskeletal system, MSCs are currently under evaluation, but so far have found access to clinical use only in few cases. The current assignment is to translate the acquired knowledge into clinical practice. Therefore, this review aims at presenting a synopsis of the up-to-date status of the use of MSCs and MSC related cell products in musculoskeletal indications. Clinical studies were included, whereas preclinical and animal study data not have been considered. Most studies published so far investigate the final outcome applying bone marrow derived MSCs. In fewer trials the use of adipose tissue derived MSCs and allogenic MSCs was investigated in different applications. Although the reported results are equivocal in the current literature, the vast majority of the studies shows a benefit of MSC based therapies depending on the cell sources and the indication in clinical use. In summary, the clinical use of MSCs in patients in orthopedic indications has been found to be safe. Standardized protocols and clear definitions of the mechanisms of action and the mode and timing of application as well as further coordinated research efforts will be necessary for finally adding MSC based therapies in standard operating procedures and guidelines for the clinicians treating orthopedic disorders.
Doing competence: On the performativity of literacy and numeracy from a post-structural viewpoint
Authors: Heilmann Lisanne 
Published: May 2020

AbstractInternational large-scale assessments like the Programme for the International Assessment of Adult Competences (PIAAC) assess literacy and numeracy proficiency as abstract competences, assuming they are cognitive skills and therefore objectively and universally measurable. However, research into how people’s lives are affected by notions ofliteracyandnumeracyhas shown that both are influenced by social conventions and expectations which are embedded in power relations and ideology. Competences and practices are situated in their social context, and they are products of historical processes which include their construction through the way they are referred to by both experts and the general public. The purpose of this article is to look at literacy and numeracy from a post-structural point of view, questioning the individualised understanding of literacy and numeracy as abstract competences which people simply “have”. The author explores the possibility of viewing these basic competences as constructed through how they are actively performed (e.g. when someone engages in reading, writing or calculating for a particular purpose in a particular context) and referred to (e.g. when someone is pronounced “literate” or “competent”). The author points out that being acknowledged and addressed as competent and literate opens up possibilities, just as being viewed as lacking these competences can allow access to (learning) opportunities. Simultaneously and ambivalently, constructed notions of competence both liberate and subordinate individuals. They create power relations and vulnerabilities which often remain unacknowledged.
Modeling the Time Delay Problem of Galactic Cosmic Ray Flux in Solar Cycles 21 and 23
Authors: Siluszyk M. , Iskra K. 
Published: May 2020

AbstractWe present a 2-dimensional time-dependent simulation based on Parker’s transport equation (PTE) describing the propagation of energetic astroparticles – cosmic rays (CR) in the heliosphere. PTE is a second order partial differential equation containing four major processes: diffusion, convection, drift, and adiabatic cooling responsible for modulation of the CR flux in the heliosphere. We implement in the numerical simulation, a few physical parameters as the tilt angle, $\delta $δ, of the heliospheric current sheet (HCS), module, $B$B, of the interplanetary magnetic field (IMF), and variations of drift effect of the CR particles with solar activity (SA). Our approach is the implementation of two independent parameters (proxies), $\gamma $γ and $\nu $ν. The parameters $\gamma $γ and $\nu $ν are calculated from various independent sources, $\gamma $γ, from neutron monitors (NM) daily data, and $\nu $ν, using the IMF hourly data. The solutions of PTE obtained from our numerical model are compared with the variations of the CR flux recorded by NMs. We prove the existence of a varying delay time (DT) between the changes of galactic cosmic ray (GCR) intensity and the parameters characterizing SA. Based on our investigation, we obtained different DTs in Solar Cycles 21 and 23. We conclude that the calculated DTs, after comparison with the observed DTs, are useful parameters for the study of GCR transport in the heliosphere.
Tighter reformulations using classical Dawson and Sankoff bounds for approximating two-stage chance-constrained programs
Authors: Singh Bismark 
Published: May 2020

AbstractWe extend and improve recent results given by Singh and Watson on using classical bounds on the union of sets in a chance-constrained optimization problem. Specifically, we revisit the so-called Dawson and Sankoff bound that provided one of the best approximations of a chance constraint in the previous analysis. Next, we show that our work is a generalization of the previous work, and in fact the inequality employed previously is a very relaxed approximation with assumptions that do not generally hold. Computational results demonstrate on average over a 43% improvement in the bounds. As a byproduct, we provide an exact reformulation of the floor function in optimization models.

AbstractAchieving sustainable development globally requires multilevel and interdisciplinary efforts and perspectives. Global goals shape priorities and actions at multiple scales, creating cascading impacts realized at the local level through the direction of financial resources and implementation of programs intended to achieve progress towards these metrics. We explore ways to localize global goals to best support human well-being and environmental health by systematically comparing the UN Sustainable Development Goals (SDGs) with regionally-derived well-being dimensions that encompass components of social–ecological resilience across the Pacific Islands. Our research shows that, in the context of the Pacific, there are overlaps but also significant gaps between regional conceptions of well-being and the globally-derived SDGs. Some dimensions, related to human health and access to infrastructure and finances, are well represented in the SDGs. Other dimensions of high importance when localizing perspectives of well-being, such as those regarding connections between and across people and place and Indigenous and local knowledge, are not. Furthermore, internationally generated indicators may result in trade-offs and measurement challenges in local contexts. Creating space for place-based values in global sustainability planning aligns with international calls for transformational changes needed to achieve global goals. We identify challenges in applying SDG indicators at the local level and provide lessons learned to foster equitable and holistic approaches and outcomes for sustainability.
Is Brachytherapy Feasible After Head and Neck Cancer Reconstructive Surgery? Preliminary Report
Authors: Bartochowska Anna , Banaszewski Jacek , Wierzbicka Małgorzata 
Published: May 2020

AbstractThe purpose of the study was to evaluate the influence of interstitial postoperative brachytherapy for the vitality and quality of flaps used for reconstruction of tissue defects after head and neck cancer salvage resection. We aimed at presenting six consecutive patients with recurrent squamous cell carcinoma in head and neck region who underwent salvage surgery and tissue reconstruction with a regional or free flap followed by brachytherapy. Reconstruction was performed with a free radial forearm flap in 2 cases, with a free thigh flap in 2 cases, and with a myocutaneous lateral upper arm flap in the next 2 cases. In all patients, pulsed-dose-rate brachytherapy was used with a median value of 0.7 Gy (range 0.6–0.8 Gy) per pulse and a median total dose of 20 Gy (range 20–40 Gy). In the analyzed group, there were no serious wound and flap complications after brachytherapy. In one case, peripheral skin necrosis was noticed. No revision surgery was needed but only surgical debridement of the necrotic margins. All wounds healed within 14 days after surgery as well as donor sites which healed within 4 weeks. Based upon our data, pulsed-dose-rate brachytherapy seems to be a safe option that can be performed at the site of reconstruction in immediate postoperative period with minimal wound complications and with no impact on flap survival. Further clinical study based on larger patient series is needed to present statistically proven results.
The Negative Effects of Institutional Logic Multiplicity on Service Platforms in Intermodal Mobility Ecosystems
Authors: Schulz Thomas , Böhm Markus , Gewald Heiko , Celik Zehra , Krcmar Helmut 
Published: May 2020

AbstractDigitalization is changing the mobility sector. Companies have developed entirely new mobility services, and mobility services with pre-digital roots, such as ride-sharing and public transport, have leveraged digitalization to become more convenient to use. Nevertheless, private car use remains the dominant mode of transport in most developed countries, leading to problems such as delays due to traffic congestion, insufficient parking spaces, as well as noise and air pollution. Emerging intermodal mobility ecosystems take advantage of digital advances in mobility services by providing individual, dynamic and context-aware combinations of different mobility services to simplify door-to-door mobility and contribute to the reduction of private car use. However, the service platforms are limited in terms of functional range, for example they may lack integrated ticketing and rely on static data, which makes intermodal mobility inconvenient. This article adopts the service-dominant logic perspective to analyze service ecosystems for intermodal mobility and their service provision. Drawing on traditional institutional literature, the authors question the assumption that service logic is dominant for all actors of a service ecosystem. By applying activity theory, the article illustrates how an institutional logic multiplicity among actors can negatively affect the functional range of service platforms. The results of a qualitative study in Germany show that, in particular, the state logic of some actors, which is characterized by the obligation to provide mobility, impairs the quality of service platforms in supporting citizens in intermodal mobility.
Phosphorus phytoremediation using selected wetland plants in constructed floating mats
Authors: Chapman Katy , Boucher Jennifer 
Published: May 2020

AbstractPhosphorus (P) overloading in fresh water systems has a detrimental effect by increasing the speed of eutrophication. Phytoremediation is the use of natural plants to remove contaminants from the environment. In the current study, we tested five plants (Pteris vittata, Lemna minor, Rumex orbiculatus, Rumex verticillatus, and Typha × glauca) in the laboratory and field for phosphorus mitigation potential. In the field experiment, both root and shoot phosphorus content were evaluated, and in the laboratory study percent phosphorus removed was calculated. Our research showed in both experiments that T. glauca removed the most phosphorus (p < 0.05). In the field study, shoots of T. glauca removed on average 3.7 g P/plant, while the roots and shoots removed 12.67 g P/plant from water. In the laboratory study, the T. glauca removed 84% of the phosphorus from the water. Rumex verticillatus in both experiments had the next highest phosphorus removal rates (0.46 g P/shoot, 1.93 g P/plant (root + shoot), and 90% removal in the laboratory study). These results show great potential for T. glauca and R. verticillatus in the mitigation of phosphorus from fresh water systems.

AbstractEpithelial ovarian cancer (EOC) is one of the leading causes of death from gynecologic cancers and peritoneal dissemination is the major cause of death in patients with EOC. Although the loss of 4.1N is associated with increased risk of malignancy, its association with EOC remains unclear. To explore the underlying mechanism of the loss of 4.1N in constitutive activation of epithelial-mesenchymal transition (EMT) and matrix-detached cell death resistance, we investigated samples from 268 formalin-fixed EOC tissues and performed various in vitro and in vivo assays. We report that the loss of 4.1N correlated with progress in clinical stage, as well as poor survival in EOC patients. The loss of 4.1N induces EMT in adherent EOC cells and its expression inhibits anoikis resistance and EMT by directly binding and accelerating the degradation of 14-3-3 in suspension EOC cells. Furthermore, the loss of 4.1N could increase the rate of entosis, which aggravates cell death resistance in suspension EOC cells. Moreover, xenograft tumors in nude mice also show that the loss of 4.1N can aggravate peritoneal dissemination of EOC cells. Single-agent and combination therapy with a ROCK inhibitor and a 14-3-3 antagonist can reduce tumor spread to varying degrees. Our results not only define the vital role of 4.1N loss in inducing EMT, anoikis resistance, and entosis-induced cell death resistance in EOC, but also suggest that individual or combined application of 4.1N, 14-3-3 antagonists, and entosis inhibitors may be a promising therapeutic approach for the treatment of EOC.

Published: May 2020

AbstractIncreasingly, graduates are taking much more time in the transition from school to work. Recent research suggests that the ability to adjust quickly plays a key role in the transition process. This is even more important today given the tough labor market realities such as exacerbated unemployment levels and global competitions for the few available job openings. Yet new graduates often lack experience and certain skills that employers look for. Those unable to maneuver through the School-To-Work Transition (STWT) quickly may experience further challenges in their career development process. Using a sample of 516 students in their final semester of their university studies in Ugandan and Kenya, the present study examines the role of psychological resources, namely psychological capital and the mechanisms (i.e. Career Engagement - CE, Perceived Employability - PE) through which it works to affect students’ readiness for STWT as well as positively evaluating their career success. The major findings of the study reveal substantial positive direct effects of psychological capital on perceived employability, readiness for STWT, and career satisfaction. The double mediation results show that psychological capital indirectly affects the readiness for STWT via career engagement and internal PE, while psychological capital indirectly affects career satisfaction via career engagement and external PE. The implications of these results are discussed.

Abstract
Purpose
To examine factors associated with prescribing anti-dementia medicines (ADM), atypical antipsychotics (A-APM), typical antipsychotics (T-APM), anxiolytics and other psychostimulants (OP) in the residents of long-term care institutions (LTCIs).

Methods
A cross-sectional survey of a country-representative sample of randomly selected LTCIs in Poland, conducted in 2015–2016. First, we identified 1035 residents with cognitive impairment (CI) among all 1587 residents. Next, we randomly selected 20 residents from each institution. Study sample consists of 455 residents with CI: 214 recruited from 11 nursing homes and 241 from 12 residential homes. We used InterRAI-LTCF questionnaire and drug dispensary cards administered on the day of data collection to assess use of drugs. Multiple correspondence analysis (MCA), descriptive and logistic regression analyses were performed.

Results
The residents were treated with ADM (13.4%), OP (14.3%), antipsychotics (46.4%) including A-APM (24.2%) and T-APM (27.9%), and anxiolytics (28.4%). Hydroxyzine was used most often among anxiolytics (71.3%). Prescribing of ADM was more likely in Alzheimer’s disease (OR = 4.378; 95%CI 2.173–8.823), while OP in other dementia (OR = 1.873; 95%CI 1.007–3.485). Administration of A-APM was more likely in older residents (OR = 1.032, 95%CI 1.009–1.055), and when delusions appeared (OR = 2.082; 95%CI 1.199–3.613), while there were no neuropsychiatric factors increasing the odds of T-APM use. Prescribing of anxiolytics was less likely in moderate CI (by 47.2%) than in residents with mild CI.

Conclusion
Current practices of prescribing psychotropics are inadequate in Polish LTCIs, especially in terms of use of T-APM and hydroxyzine. More attention should be given to motivate physicians to change their prescribing practices.

AbstractSemi-transparent perovskite solar cells have the competitive edge of being employed for building integrated photovoltaics due to their esthetic benefits as light harvesting windows/facades. Perovskites have received considerable attention in recent years as a thin film photovoltaic alternative, that can also be tweaked for its transparency, evolving from potentially high bandgaps that are suited for semi-transparent solar cell fabrication. Due to the existing trade of between the efficiency and transparency of a perovskite solar cell, tuning the band gap can address this by making a bridge between the aforementioned parameters. We report our findings on the use of a wide-bandgap perovskite MAPbBr3, with a rational energetic level hole transport materials based on polycyclic aromatic hydrocarbon molecules that can be a promising alternative class of p-type material. In the present work, DBP (Dibenzo{[f,f′]-4,4′,7,7′-tetraphenyl}diindeno[1,2,3-cd :1′,2′,3′-lm]perylene was evaluated with high bandgap as well as with mixed (FAPbI3)0.85(MAPbBr3)0.15 perovskites for the fabrication of solar cell. DBP-based solar cells yielded competitive power conversion efficiencies as compared with classical HTMs.
