Unburied Practices of Memory: The Holocaust and the Polish-Jewish Relations in Joanna Rudniańska’s Kotka Brygidy (2007) and XY (2012)
Authors: Świetlicki Mateusz , Michułka Dorota 
Published: February 2022

AbstractIn many Polish children’s books published in the last twenty years the relationship between Jews and Poles during the Holocaust is presented as an unburied theme which can be interpreted in the context of both collective and private/individual cultures of remembrance. Therefore, in this case, we deal with experiences confirmed in the cultural and written order rather than existentially faced. In contemporary Poland, a practically monoethnic and predominantly Catholic country, where the largest number of Jews killed by the Nazis lived before World War II, there is a syndrome of silence concerning the Holocaust. This paper focuses on analysing Joanna Rudniańska’s Kotka Brygidy [Brygida’s Cat] (2007) and XY (2012), two unique works in the genre of Polish Holocaust children’s fiction which combine parable, magic realism, and postmodern fairy tale. The authors argue that Rudniańska’s texts belong not only to the group of literary works known as children’s literature of atrocity or the literature of genocide for young people but also literature of testimony with its authenticity and referentiality as an element of figural realism. Analysing Rudniańska’s works, they show how she, the daughter of a Holocaust survivor who did not want to talk about the traumatic war experience, not only writes about the unburied themes but also crosses genre boundaries by mixing realistic figures with stories firmly rooted in a poetic, metaphorical, and magic atmosphere with subjective and expressive narration.
Learning Strategies in Self-directed Language Learning Using Mobile Technology in Higher Education: A Systematic Scoping Review
Authors: Lai Yuzhi , Saab Nadira , Admiraal Wilfried 
Published: February 2022

AbstractLanguage learners in higher education increasingly use out-of-class self-directed learning facilitated by mobile technology. In order to make informed educational decisions, this study sets out to provide an overview of empirical research into learning strategies that self-directed learners use with the support of mobile technology in language learning. Twenty studies were selected and systematically analysed, revealing the cognitive, metacognitive, social and affective strategies that self-directed learners used in their language learning processes. Low-cognitive strategies appeared to be more commonly reported than high-cognitive strategies. The use of metacognitive strategies was more closely associated with the forethought phase and performance phase than with the self-reflection phase, yet only a few articles reported all three metacognitive phases. Three kinds of social strategies were examined, and only one affective strategy was reported. Finally, implications of these findings and directions for future research are provided for self-directed learners, practitioners and researchers to facilitate self-directed learning and future work.
Macrophyte communities as indicators of the ecological status of drainage canals and regulated rivers (Eastern Poland)
Authors: Tarkowska-Kukuryk Monika , Grzywna Antoni 
Published: February 2022

AbstractMacrophytes are one of the biological elements for assessing the ecological status. Macrophyte communities were studied in six artificial (drainage canal and ditches) or modified watercourses (regulated rivers). In order to assess the ecological status of the watercourses, studies were carried out with the use of the Macrophyte Index for Rivers (MIR) proposed in the Water Framework Directive. Macrophyte communities were mainly represented by helophytes (12 species in total), and the highest percentage area cover (50–75% of the site) was observed for pleustophytes (Lemna spp.). Macrophytes communities were affected by the gradients of hydromorphological (canal modification, flow type, and shading) and parameters water quality (nutrients and water transparency). The relationships were highly species-specific. In accordance with the MIR values, the ecosystems were classified as having poor (drainage canal), moderate (regulated rivers), or good (drainage ditches) ecological status.

AbstractThe monitoring of contaminants represents a priority to preserve the integrity of marine ecosystems, as well as to plan and to manage restoration activities in order to protect environmental and human health. In the present study, a 6-months active biomonitoring was performed to explore the levels of eighteen trace and toxic elements, including heavy metals (TEs; i.e. Al, As, Ca, Cd, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, P, Pb, Sr, Ti, and Zn), accumulated in soft tissues of blue mussel (Mytilus edulis Linnaeus, 1758) individuals transplanted at different depths (5- and 15-m depth) in five locations within the Flekkefjord fjord (Southern Norway). As this area suffered a long-lasting contamination due to both organic and inorganic contaminants, a series of restoration activities were activated to tackle and to prevent potential risks for ecosystem and local population. Our results demonstrated that the levels of TEs accumulated in edible tissues of transplanted mussels in the Flekkefjord fjord were generally low before the beginning of the restoration activities. However, location- and time-specific differences in the accumulation of TEs were noted after the implementation of such activities. Interestingly, the levels of Fe and Mn significantly increased after the beginning of the restoration activities, likely because the release of these TEs from the slag used in such operations and/or resuspension of contaminated sediments. However, assuming that native mussels can accumulate the same TEs at levels measured in transplanted individuals, our results suggest a substantial safety for human consumption of native mussels from the Flekkefjord fjord, regardless of restoration activities.
Homogeneity and Best Practice Analyses in Hospital Performance Management: An Analytical Framework
Authors: Zarrin Mansour , Schoenfelder Jan , Brunner Jens O. 
Published: February 2022

AbstractPerformance modeling of hospitals using data envelopment analysis (DEA) has received steadily increasing attention in the literature. As part of the traditional DEA framework, hospitals are generally assumed to be functionally similar and therefore homogenous. Accordingly, any identified inefficiency is supposedly due to the inefficient use of inputs to produce outputs. However, the disparities in DEA efficiency scores may be a result of the inherent heterogeneity of hospitals. Additionally, traditional DEA models lack predictive capabilities despite having been frequently used as a benchmarking tool in the literature. To address these concerns, this study proposes a framework for analyzing hospital performance by combining two complementary modeling approaches. Specifically, we employ a self-organizing map artificial neural network (SOM-ANN) to conduct a cluster analysis and a multilayer perceptron ANN (MLP-ANN) to perform a heterogeneity analysis and a best practice analysis. The applicability of the integrated framework is empirically shown by an implementation to a large dataset containing more than 1,100 hospitals in Germany. The framework enables a decision-maker not only to predict the best performance but also to explore whether the differences in relative efficiency scores are ascribable to the heterogeneity of hospitals.
Effect of Anthropogenic Activities on the Population of Moor Macaques (Macaca maura) in South Sulawesi, Indonesia

Published: February 2022

AbstractForest loss due to anthropogenic activities is one of the main causes of plant and animal species decline. Studying the species’ population status (i.e., density, abundance, and geographic distribution) on a regular basis is one of the main tools to assess the effect of anthropogenic activities on wildlife, to monitor population dynamics and to intervene with effective conservation strategies when the population of an endangered species declines. On Sulawesi Island, Indonesia, anthropogenic activities, such as agriculture, are decreasing the remaining natural habitats available for several endemic and endangered species. The effect of this forest loss on the threatened moor macaques (Macaca maura) in South Sulawesi is unknown, and data on the population status of this species are needed to design effective conservation strategies. To assess the population status of the moor macaques, we walked linear transects (N = 29, survey effort = 114 km) at six sites between November 2019 and March 2020 to estimate macaque population density and encounter rate. We tested the effect of anthropogenic activities on macaque encounter rate. Our global density estimate (24 individuals/km2) was lower than the overall estimate from the most detailed survey conducted on this species, which covered its whole geographic distribution (36.1 individuals/km2). However, these results should be interpreted with caution because the previous density estimate falls within the confidence intervals of our estimate. Furthermore, we found regional declines in moor macaque encounter rates in at least two sites compared with previous studies. We found a high presence of anthropogenic activity in the forests inhabited by macaques. Moor macaques were less abundant in open areas with no forest (i.e., clear cuttings) than in forested areas, and in the presence of nonspecies-specific hunting traps (i.e., wire-loop traps). Moreover, moor macaques were more abundant in areas with a higher presence of humans and domestic animals. Overall, our data suggest that the population of this species may be declining in certain regions but further surveys are needed to corroborate whether this is occurring across the entire geographic distribution.
Addressing inequity and underachievement: Intervening to improve middle leaders’problem-solving conversations
Authors: Patuawa Jacqueline Margaret , Sinnema Claire , Robinson Viviane , Zhu Tong 
Published: February 2022

AbstractReducing inequity is the moral imperative confronting today’s educational leaders. Central to reducing inequity is leaders’ ability to solve the school-based problems that contribute to it, while building the positive and trusting professional relationships required for teachers to commit to the hard work of improvement. A theory of collaborative problem-solving informed our intervention designed to improve the effectiveness of leaders’ behaviour as they worked with their teachers to accelerate the reading achievement of students yet to reach age-related standards. A concurrent mixed methods design was used to evaluate the impact of the intervention by analysing transcripts of interviews and leader-teacher conversations and student reading achievement data. Leaders’ effectiveness in their conversations improved significantly as did the reading outcomes of their target students. Our findings suggest that even short interventions grounded in strong theory with appropriate learning opportunities can affect a positive change in leadership behaviour and student outcomes.

Abstract

Background
The DiamondTemp ablation (DTA) catheter system delivers high power, open-irrigated, temperature-controlled radiofrequency (RF) ablation. This novel ablation system has not been previously used for ventricular tachycardia (VT) ablation.

Objective
Feasibility of using the DTA catheter system for VT ablation in ischaemic cardiomyopathy (ICM) patients.

Method
Ten ICM patients with optimal anti-arrhythmic drug therapy and implantable cardiac defibrillators (ICD) were recruited. VT inducibility testing was performed at the end of the procedure. ICD data for device detected VT episodes and device treated VT episodes were collected for 6-months pre- and post-ablation.

Results
Substrate analysis demonstrated reductions in the borderzone area of 4.4 cm2 (p = 0.026) and late potential area of 3.5 cm2 (p = 0.0449) post-ablation, with reductions in the mean bipolar and unipolar voltages of the ablation target areas (0.14 mV (p = 0.0007); 0.59 mV (p = 0.0072) respectively). Complete procedural success was achieved in 9 procedures. Post-ablation VT inducibility testing was not performed in 1 procedure due to a steam pop complication resulting in pericardial tamponade requiring drainage. Mean follow-up of 214 ± 33 days revealed an 88% reduction in total VT episodes (n = 266 median 16 [IQR 3–57] to n = 33 median 0; p = 0.0164) and 77% reduction in ICD therapies (n = 128 median 5 [IQR 2–15] to n = 30 median 0; p = 0.0181).

Conclusion
The DTA system resulted in adequate lesion characteristics with effective substrate modification, acute procedural success and improved outcomes at intermediate-term follow-up. Randomised controlled trials are required to compare the performance of the DTA system against conventional ablation catheters.
The jump-like PTCR effect in a Ni-BaTiO3 magnetic composite
Authors: Zajc Igor , Drofenik Mihael 
Published: February 2022

AbstractThe ceramic composites BaTiO3@Ni, composed of a conducting nickel and a highly resistive ferroelectric BaTiO3 phase, exhibiting a positive temperature coefficient of electrical resistivity (PTCR), are prepared using a conventional ceramic method at less than 1000 °C. The BaTiO3@Ni composites show a jump-like PTCR effect in electrical resistivity by about eight orders of magnitude (ρmax/ρmin ≈ 108) with ρmin < 1 Ωcm. This is the first example of a standard PTCR element with a relatively high magnetization. The grain relocations (a microstructural rearrangement) on a microscopic scale in the composite are filmed using a transmission electron microscope while heating through the ferroelectric phase transition (Curie temperature), which induces the PTCR anomaly. The resistivity anomaly of the composite is explained in terms of the ferroelectric phase transition-assisted anomaly in the electrical resistivity.
The p-Lagrangian relaxation for separable nonconvex MIQCQP problems
Authors: Andrade Tiago , Belyak Nikita , Eberhard Andrew , Hamacher Silvio , Oliveira Fabricio 
Published: February 2022

AbstractThis paper presents a novel technique to compute Lagrangian bounds for nonconvex mixed-integer quadratically constrained quadratic programming problems presenting a separable structure (i.e., a separable problems) such as those arising in deterministic equivalent representations of two-stage stochastic programming problems. In general, the nonconvex nature of these models still poses a challenge to the available solvers, which do not consistently perform well for larger-scale instances. Therefore, we propose an appealing alternative algorithm that allows for overcoming computational performance issues. Our novel technique, named the p-Lagrangian decomposition, is a decomposition method that combines Lagrangian decomposition with mixed-integer programming-based relaxations. These relaxations are obtained using the reformulated normalised multiparametric disaggregation technique and can be made arbitrarily precise by means of a precision parameter p. We provide a technical analysis showing the convergent behaviour of the approach as the approximation is made increasingly precise. We observe that the proposed method presents significant reductions in computational time when compared with a previously proposed techniques in the literature and the direct employment of a commercial solver. Moreover, our computational experiments show that the employment of a simple heuristic can recover solutions with small duality gaps.
The Comparative Roles of Mentor Self-Efficacy and Empathy in Fostering Relationship Quality with Youth

Published: February 2022

AbstractYouth mentors’ efficacy beliefs and relational skills should both influence the quality of their connections with their mentees, but a lack of research based on large, dyadic and longitudinal samples limits understanding of how mentor characteristics impact relationship quality. This study used three staged and process-focused structural equation models to (1) investigate the mutually reinforcing effects of mentor self-efficacy and empathy over time; (2) compare the longitudinal effects of mid-program mentor efficacy and empathy on end of program mentor and mentee perceptions of relationship quality; and (3) test a similar comparative model using cross-sectional end of program assessments to account for developmental changes in these variables over time. The sample consisted of 664 college-age mentor (76.5% female;$${\bar{x}}$$x¯age = 24.5, range = 21–53; 23.5% non-White) and youth mentee (41% female;$${\bar{x}}$$x¯age = 14.1, range = 10–19; 41.9% non-White) dyads. Mentor empathy predicted mentor perceptions of relationship quality at both time points and mentee perceptions at the end of the program. Mentor efficacy only predicted mentor reported relationship quality at the end of the program. The findings emphasize the importance of investing in empathy training for mentors to support both partners’ positive evaluation of the relationship. Program support to increase mentor self-efficacy should also have added value for mentors.

Abstract
Introduction
The Maternal and Child Health (MCH) Pipeline Training Program, promotes development of a diverse health workforce by training undergraduate students from underrepresented minorities. We aimed to evaluate the success of this program based on three domains: (1) demographic characteristics, (2) academic and career development, and (3) attitudes towards the field of MCH and the training programs among graduates.

Methods
Three domains of success were determined through a collaborative effort between current program directors and the funding agency project officers. The survey with questions related to the three domains was distributed via an online platform to graduates from seven sites (one former site and six current sites). Data were analyzed and presented utilizing descriptive statistics.

Results
The survey was distributed to 550 graduates, 162 responded (37% response rate). Demographically, 78% were female, 54% were Black/African American, 22% were Latinx and 83% did not report any disability. Eighty percent of respondents applied to graduate/professional schools, 67% received admission. Graduates often continued to work in MCH fields (70%). Majority felt confident and knowledgeable in the field (89%) and agreed the faculty were supportive at their training sites (90%).

Conclusion
The study highlights successes in recruiting from underrepresented minorities, particularly Black/African Americans and first-time college goers in the family into the MCH Pipeline Training Programs. Programs were successful in furthering academic and career development for most trainees. Attitudes towards MCH and the training programs were overwhelmingly positive. Continued support of these programs is critical in addressing health disparities and achieving health equity.

Abstract
Purpose
Cerebro-spinal fluid leak after transsphenoidal surgery for pituitary adenomas may be prevented by skull base reconstruction with fat autograft. However, graft changes may interfere with the interpretation of postoperative images. Our aim is to describe the radiological evolution of the fat autograft.

Methods
A retrospective analysis was performed, including patients undergoing a transsphenoidal surgery for pituitary adenomas with a fat autograft for skull base reconstruction. Clinical and radiological data were collected, with assessment of fat autograft and extent of resection. Statistical analysis was performed using Kruskal–Wallis and Wilcoxon signed-rank test while Spearman’s Rho was used to analyze the relationship between variables.

Results
Seventy-two patients were included. Macroadenomas were diagnosed in 62 cases (86.1%) and in 21 cases an invasion of the cavernous sinus was described (29%). Gross total resection was achieved in 84.7% of cases. The volume of the fat graft significantly decreased between 3 months and 1 year after surgery (p = 0.01) and between 1 year and the last follow-up (mean 4.63 years, p < 0.01). Fat signal ratio significantly diminished between 3 months and 1 year in unenhanced and enhanced T1-weighted sequences (p = 0.04 and p = 0.02 respectively). Volume reduction was related to the decrease in signal ratio in unenhanced T1 sequences (p = 0.008).

Conclusion
Fat resorbs with time: almost 50% of the fat volume is lost during the first year after surgery and 60% is resorbed at 4.6 years. T1-signal, before and after gadolinium injection, also decreases during the first year, probably because of the progressive fibrosis of the graft. This information will contribute to the interpretation of postoperative images.
Inquiring Systems and Development Led Inquiry: Uniting the Efforts of Farmers, Development Professionals, and Researchers
Authors: Ramsay Gavin , Narain Nivedita , Bhanjdeo Arundhita 
Published: February 2022

AbstractThis paper introduces Development Led Inquiry (DLI) as an approach to improve situations incorporating relationships between third sector organisations (TSOs) and agricultural scientists, universities, and the public-sector agricultural establishment. There is limited scholarly work on the role of TSOs in agricultural research. Current approaches appear premised on TSOs being researched upon, and recipients of research outcomes rather than partners in generation and application of new knowledge. DLI expands the boundaries of research systems and roles of TSOs as supporters within them. DLI builds on partnerships between NGOs, farmers’ organisations, and women’s associations; it integrates researchers and research organisations to develop, manage and report knowledge generation and application. DLI is dynamic and developmental with learning for all participants central to the process. DLI unsettles current power structures within research systems and sees research and knowledge generation as a supporter rather than leader of development. DLI is embedded in an inquiring systems approach and applies six interrelated conceptual systems thinking tools. The approach emerged from, and was applied in, a twelve-year agricultural research project in India, and was subsequently introduced to, and further developed in a research project in Pakistan.
