Published: April 2021

AbstractToxic metal phytoextraction potential of some higher plants, the white mustard (Sinapis alba L.), perennial rye grass (Lolium perenne L.) and also two cultivated plants, as green pea (Pisum sativum L. var. Rajnai törpe), radish (Raphanus sativus L. var. Szentesi óriás vaj), was studied in a field experiment, along the river Danube in close vicinity of an industrial town, Dunaújváros, Hungary. Soil/sediment and the various plant organs (leaves, stems and roots) were assessed for the contamination with some potentially toxic elements (PTE), such as the cadmium (Cd), nickel (Ni), copper (Cu), and zinc (Zn). It was found that Cd and Ni concentration was below, while the Cu and Zn elements were above the Hungarian permissible limits in each of the studied soil/sediment samples. Bioconcentration factor (BAF) was less than 1 in the shoot biomass of test plant samples and followed the order of Cu > Zn > Cd and Ni. Phytoremediation potential of selected test plants was found to be rather limited. The translocation factor (TF) was more than 1 for Cu and Zn elements, at each test plants. Cadmium was translocated into the leaves in case of the radish, only. Considering of the potential human daily intake of metals (DIM), it was less than 1 both for the adults and for the children. Health risk index (HRI) values of children, however, were higher than 1 for the Cd in case of radish, and for Zn and Cu in case of the pea. Results suggest that consumption of these plants grown in gardens of contaminated sediments can result in some risks for citizens in the industrial town of Dunaújváros. Further studies are required to identify appropriate plants with greater toxic metal phytoextraction potential.
Combating Academic Corruption and Enhancing Academic Integrity through International Accreditation Standards: The Model of Qatar University
Authors: Mattar Mohamed Y. 
Published: April 2021

AbstractAcademic institutions aim at achieving the highest standards of education and learning. Consequently, they prohibit academic corruption such as cheating or plagiarism. This article examines how international accreditation and quality assurance standards embody academic integrity as a main factor in deciding whether an academic institution should be accredited, and what ranking should an academic institution acquire in a competitive contest for educational excellence. Academic integrity is broadly defined to include, in addition to cheating and plagiarism, compliance with standards of human rights, labor rights, corporate social responsibility, ant-corruption measures, environmental protection, social media usage, protection of underage students, anti-radicalization and extremism, avoidance of conflict of interest, faculty professionalism, students codes of conduct and human experimentation. Academic institutions should adopt policies that are designed to address these diverse standards and accommodate diversity and enhance access to education for all without discrimination. Academic institutions should also strictly require the highest standards in teaching and research. This article will discuss the different policies, laws, rules and regulations adopted by Qatar University as a model for incorporating academic integrity, which may be of interest to the international higher education community. This article will ask two main questions; are accrediting institutions asking the right questions to find out whether an academic institution strictly adheres to a policy of academic integrity, and whether policies adopted by academic institutions, Qatar University as a model, are adequate to address various violations of academic integrity.
Partially distributed outer approximation

Published: April 2021

AbstractThis paper presents a novel partially distributed outer approximation algorithm, named PaDOA, for solving a class of structured mixed integer convex programming problems to global optimality. The proposed scheme uses an iterative outer approximation method for coupled mixed integer optimization problems with separable convex objective functions, affine coupling constraints, and compact domain. PaDOA proceeds by alternating between solving large-scale structured mixed-integer linear programming problems and partially decoupled mixed-integer nonlinear programming subproblems that comprise much fewer integer variables. We establish conditions under which PaDOA converges to global minimizers after a finite number of iterations and verify these properties with an application to thermostatically controlled loads and to mixed-integer regression.
Developmental Interplay between Ethnic, National, and Personal Identity in Immigrant Adolescents

Published: April 2021

AbstractDeveloping a personal identity is a core developmental task for all adolescents. Immigrant adolescents need to integrate the meaning that their belonging to their ethnic group and the receiving nation has for them into their personal identity. The purpose of this study was to examine the longitudinal interplay between personal, ethnic, and national identities of a middle school sample of immigrant youth (N = 765,Mage = 12.7 years,SD = 0.6 at T1; 46% girls) enroled in Greek schools. Data were collected in three waves with repeated measures. To test the link between these identities, two trivariate Cross-Lagged Panel Models were ran, one examining identity exploration and the other examining identity commitment. The results revealed robust within time positive links between ethnic, national and personal identities for both exploration and commitment at all three time-points. There was some evidence that ethnic and national identities were negatively linked longitudinally, and limited support for longitudinal associations between these domains and personal identity. Follow-up analyses suggest that these processes may be specific to second generation youth and that findings may differ by ethnic background. Finally, the findings that emerged are discussed with attention to the socio-political climate in the receiving nation.
The prospect of synthesis of PES/PEG blend membranes using blend NMP/DMF for CO2/N2 separation

Published: April 2021

AbstractCarbon dioxide (CO2) emissions have been the root cause for anthropogenic climate change. Decarbonisation strategies, particularly carbon capture and storage (CCS) are crucial for mitigating the risk of global warming. Among all current CO2 separation technologies, membrane separation has the biggest potential for CCS as it is inexpensive, highly efficient, and simple to operate. Polymeric membranes are the preferred choice for the gas separation industry due to simpler methods of fabrication and lower costs compared to inorganic or mixed matrix membranes (MMMs). However, plasticisation and upper-bound trade-off between selectivity and permeability has limited the gas separation performance of polymeric membranes. Recently, researchers have found that the blending of glassy and rubbery polymers can effectively minimise trade-off between selectivity and permeability. Glassy poly(ethersulfone) (PES) and rubbery poly(ethylene) glycol (PEG) are polymers that are known to have a high affinity towards CO2. In this paper, PEG and PES are reviewed as potential polymer blend that can yield a final membrane with high CO2 permeance and CO2/nitrogen (N2) selectivity. Gas separation properties can be enhanced by using different solvents in the phase-inversion process. N-Methyl-2-Pyrrolidone (NMP) and Dimethylformamide (DMF) are common industrial solvents used for membrane fabrication. Both NMP and DMF are reviewed as prospective solvent blend that can improve the morphology and separation properties of PES/PEG blend membranes due to their effects on the membrane structure which increases permeation as well as selectivity. Thus, a PES/PEG blend polymeric membrane fabricated using NMP and DMF solvents is believed to be a major prospect for CO2/N2 gas separation.
Taking Watsuji online: betweenness and expression in online spaces
Authors: Osler Lucy , Krueger Joel 
Published: April 2021

AbstractIn this paper, we introduce the Japanese philosopher Tetsurō Watsuji’s phenomenology of aidagara (“betweenness”) and use his analysis in the contemporary context of online space. We argue that Watsuji develops a prescient analysis anticipating modern technologically-mediated forms of expression and engagement. More precisely, we show that instead of adopting a traditional phenomenological focus on face-to-face interaction, Watsuji argues that communication technologies—which now include Internet-enabled technologies and spaces—are expressive vehicles enabling new forms of emotional expression, shared experiences, and modes of betweenness that would be otherwise inaccessible. Using Watsuji’s phenomenological analysis, we argue that the Internet is not simply a sophisticated form of communication technology that expresses our subjective spatiality (although it is), but that it actually gives rise to new forms of subjective spatiality itself. We conclude with an exploration of how certain aspects of our online interconnections are hidden from lay users in ways that have significant political and ethical implications.
Flavonoids of the Caryophyllaceae
Authors: Jakimiuk Katarzyna , Wink Michael , Tomczyk Michał 
Published: April 2021

AbstractThe plant family Caryophyllaceae, commonly known as the pink family, is divided into 3 subfamilies and contains over 80 genera with more than 2600 species that are widely distributed in temperate climate zones. Plants belonging to this family produce a variety of secondary metabolites important in an ecological context; however, some of these metabolites also show health-promoting activities. The most important classes of phytochemicals include saponins, phytoecdysteroids, other sterols, flavonoids, lignans, other polyphenols, essential oils, andN-containing compounds such as vitamins, alkaloids or cyclopeptides. Flavonoids are polyphenolic compounds that remain one of the most extensively studied constituents of the Caryophyllaceae family. Numerous structurally diverse aglycones, including flavones, flavonols, flavonones (dihydroflavones), flavonols, isoflavones, and theirO- orC-glycosides, exhibit multiple interesting biological and pharmacological activities, such as antioxidant, anti-inflammatory, anti-oedemic, antimicrobial, and immunomodulatory effects. Thus, this review analysed the flavonoid composition of 26 different genera and more than 120 species of Caryophyllaceae for the first time.

AbstractSMARCA4-deficient thoracic sarcoma (SMARCA4-DTS) is a recently identified aggressive subtype of sarcoma. We present the case of a 44-year-old man who underwent a surgery for a perforated small intestine. Compued tomography scan revealed a tissular mediastino–pulmonary mass.Histopathological examination of the intestinal mass shown a malignant tumour with a typical epithelioid and rhabdoid cells, numerous mitoses and large necrosis. A large panel of immunohistochemistry revealed loss of SMARCA4 and SMARCA2 and allowed the diagnosis of SMARCA4-DTS. It is important to consider SMARCA4-deficient thoracic sarcoma in the differential diagnosis of tumours showing suggestive morphologic features in patients of all ages, especially in the case of metastasis associated with thoracic mass.

Abstract
Purpose of Review
Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive neoplasms, bearing a terrible prognosis. Stage III tumors, also known as locally advanced pancreatic cancer (LAPC), are unresectable, and current palliative chemotherapy regimens have only modestly improved survival in these patients. At this stage of disease, interventional techniques may be of value and further prolong life. The aim of this review was to explore current literature on locoregional percutaneous management for LAPC.

Recent Findings
Locoregional percutaneous interventional techniques such as ablation, brachytherapy, and intra-arterial chemotherapy possess cytoreductive abilities and have the potential to increase survival. In addition, recent research demonstrates the immunomodulatory capacities of these treatments. This immune response may be leveraged by combining the interventional techniques with intra-tumoral immunotherapy, possibly creating a durable anti-tumor effect. This multimodality treatment approach is currently being examined in several ongoing clinical trials.

Summary
The use of certain interventional techniques appears to improve survival in LAPC patients and may work synergistically when combined with immunotherapy. However, definitive conclusions can only be made when large prospective (randomized controlled) trials confirm these results.

Abstract
Purpose
We aimed to evaluate the current situation of electronic health records (EHRs) and patient registries in the oncology departments of hospitals in Spain.

Methods
This was a cross-sectional study conducted from December 2018 to September 2019. The survey was designed ad hoc by the Outcomes Evaluation and Clinical Practice Section of the Spanish Society of Medical Oncology (SEOM) and was distributed to all head of medical oncology department members of SEOM.

Results
We invited 148 heads of oncology departments, and 81 (54.7%) questionnaires were completed, with representation from all 17 Spanish autonomous communities. Seventy-seven (95%) of the respondents had EHRs implemented at their hospitals; of them, over 80% considered EHRs to have a positive impact on work organization and clinical practice, and 73% considered that EHRs improve the quality of patient care. In contrast, 27 (35.1%) of these respondents felt that EHRs worsened the physician–patient relationship and conveyed an additional workload (n = 29; 37.6%). Several drawbacks in the implementation of EHRs were identified, including the limited inclusion of information on both outpatients and inpatients, information recorded in free text data fields, and the availability of specific informed consent. Forty-six (56.7%) respondents had patient registries where they recorded information from all patients seen in the department.

Conclusion
Our study indicates that EHRs are almost universally implemented in the hospitals surveyed and are considered to have a positive impact on work organization and clinical practice. However, EHRs currently have several drawbacks that limit their use for investigational purposes.

Measurement of shopping addiction and its relationship with personality traits and well-being among Polish undergraduate students
Authors: Uzarska Aleksandra , Czerwiński Stanisław K. , Atroszko Paweł Andrzej 
Published: April 2021

AbstractThere is still a scarcity of studies showing the relative contribution of different personality characteristics differentiating various behavioral addictions within an integrated model. In comparison to other addictions, fairly little is known about the role of specific personality traits in compulsive shopping. In addition, few studies have investigated the unique contribution of shopping addiction in terms of explaining different facets of well-being above and beyond personality characteristics previously shown to be related to psychosocial functioning. The present study shows validation of the Bergen Shopping Addiction Scale (BSAS) and a tentative integrated model of potential shopping addiction personality risk factors. BSAS was administered to 1156 Polish students. In addition, demographic variables, and personality traits (Big Five), self-esteem, self-efficacy, perceived narcissism, loneliness, social anxiety, and well-being indicators were measured. BSAS had acceptable fit with the data and demonstrated good reliability. The investigated model showed that shopping addiction was related to higher extraversion, perceived narcissism, and social anxiety, and lower agreeableness and general self-efficacy. Woman and older participants scored higher on BSAS. Shopping addiction was further related to all facets of impaired well-being and explained worse general health, and decreased sleep quality above and beyond other variables in the model. The results support the notion that shopping addiction may have specific personality risk factors with low agreeableness as an outstanding characteristic. This has implications for the development of early prevention and intervention programs.
Biomass Allocation and Root Characteristics of Early-Stage Poplars (Populus spp.) for Assessing Their Water-Deficit Response During SRC Establishment

Published: April 2021

AbstractEarly above- and belowground biomass fractionation, root diameter composition and allocation of cumulated fine root length per total leaf area of Populus clones have been measured for a pre-assessment of the risk for plantation establishment during spring drought conditions. Four clones of Populus × euramericana, and one P. nigra × P. maximowiczii clone (cv. Max 3), were planted in sandy mix substrate and were exposed to one normal and one deficit watering regime over 65-day greenhouse experiments conducted during early summer. The P. × euramericana hybrids showed plasticity of their root biomass fractions. Although clone Max 3 was among the productive clones, even under deficit watering, it was not able to respond plastically to deficit watering. It showed no increase in the root biomass fraction and no increase in the ratio of cumulated fine root length per total leaf area. Therefore, the clone Max 3 should not be planted under high risk for spring drought. Planting the investigated P. × euramericana clones under water deficit likely involves a lower risk, but clone differences within this group must be considered. It can be concluded that the water deficit response of biomass allocation to roots and of the ratio of fine root length per unit leaf area is suitable traits to improve drought risk assessments that are based on yield response of poplar clones to drought. Percent plant loss data and the yield at the end of the first SRC rotation will be suitable to verify the present greenhouse assessment.

Authors: Powell G. M. , Murthy N. S. , Johnson A. C. 
Published: April 2021

Abstract
Purpose of Review
Throwing athletes are vulnerable to elbow injuries, especially in the medial elbow, related to high stress and valgus load in both acute and chronic settings as a result of this complex biomechanical action. This current review details the relevant anatomy and imaging features of common elbow pathology identified with radiographs and MRI in throwing athletes.

Recent Findings
Although elbow pathology in throwing athletes is well documented, advances in imaging technology and technique, particularly with MRI, have allowed for more detailed and accurate imaging description and diagnosis.

Summary
Pathology of thrower’s elbow occurs in predictable patterns and can be reliably identified radiologically. Clinical history and physical examination should guide radiologic evaluation initially with radiographs and followed by an MRI optimized to the clinical question. Constellation of clinical, physical, and radiologic assessments should be used to guide management.
The ABC Concept—Value Added to the Earth Heritage Interpretation?
Authors: Pásková M. , Zelenka J. , Ogasawara T. , Zavala B. , Astete I. 
Published: April 2021

AbstractHolistic interpretation of Earth heritage is one of the most important tasks of UNESCO Global geoparks. The ABC (abiotic, biotic, and cultural interconnections) concept is a potential interpretive approach used in Earth heritage popularization through geotourism. Apart of the deeper understanding of this concept, this study explores the application of this concept in selected geoparks. The Colca and Volcanoes Andagua UNESCO Global Geopark (Peru) and Muroto UNESCO Global Geopark (Japan) served as a case study in the frame of this qualitative research conducted during the summer 2019. Results show that the ABC approach is nearly perfectly understood by both geoparks, however there are both internal and external factors which influence the extent and form of how this concept is applied in practice. Except for specific geographical settings, different stages of geopark product development, and different managerial approaches, they mainly include the level of scientific knowledge and general education in the given geopark, as well as level of knowledge management and networking with another UNESCO global geoparks. The more experienced Muroto Geopark interpretation exhibits a comparatively higher level of visible ABC application, while the Colca and Volcanoes Andagua Geopark can benefit in the future from the natural inclination and ability of the local people to integrate the cultural aspects into their Earth heritage interpretation.
