Chronic pain healthcare workers’ challenges in pain management and receptiveness towards VR as an adjunct management tool: a qualitative study
Authors: Li Lydia Weiling , Yi Tan Hui , Khaing Nang Ei Ei
Published: April 2024

Background

Chronic pain is often a debilitating condition that affects individuals physically and mentally. Reliance on pharmacotherapy for pain management comes with risks of analgesic misuse and dependence. Hence, non-pharmacologic treatment plays a crucial role in pain management. Virtual reality is a novel method in chronic pain management. However, there is little understanding about healthcare providers’ perspectives on the use of virtual reality technology in managing chronic pain. This study aims to explore the current management challenges faced by chronic pain healthcare providers and their perspectives on using virtual reality as adjunctive therapy in managing chronic pain.

Method

Individual semi-structured interviews were conducted among all chronic pain healthcare providers in a tertiary hospital. The interviews were analysed using qualitative thematic analysis.

Results

Eight chronic pain healthcare providers participated in this study. Financial issues were cited as one of the biggest barriers to utilisation of non-pharmacological treatment. Participants highlighted the importance of psychosocial support from family and healthcare providers. Challenges identified included absence of patient engagement and lack of awareness about pain management among healthcare providers as well as the lack of an integrated multidisciplinary approach in our healthcare system. Participants were receptive towards the use of virtual reality in chronic pain management and offered ample opinions and suggestions for its application in chronic pain management.

Conclusions

A multilevel, multifaceted approach is needed to improve chronic pain management. Virtual reality technology could be considered as an adjunct therapy to address some of the challenges and limitations identified in this study.
Experience of violence and attitudes of staff members towards coercion in psychiatric settings: observational study
Authors: Wullschleger Alexandre , Chatton Anne , Kuenzi Noémie , Baeriswyl Rachel , Kaiser Stefan , Bartolomei Javier
Published: April 2024

Background

Among important dimensions related to the use of coercive measures, professionals’ attitude towards coercion is of particular interest. Little is known about how experiences of violence in the workplace might influence these attitudes.

Aims

The present study aimed to investigate potential correlates of attitudes towards coercion, especially experiences of violence in the workplace.

Method

Mental health professionals were contacted through an online survey to assess their attitudes towards coercion using the Staff Attitude to Coercion Scale (SACS). The three subscales of the SACS (critical, pragmatic and positive attitudes) were analysed in a multivariate multiple linear regression, using a set of covariates including experiences of violence in the workplace. We hypothesised that experience of violence in the workplace would correlate with less critical attitudes of staff members towards coercion.

Results

A total of 423 professionals were included in the regression analysis. Age, professional category, feeling of insecurity, having witnessed or used coercion, and the emotional burden associated with coercive measures had a joint significant effect on the three SACS subscales. A feeling of insecurity, but not the experience of violence, was associated with a less critical, more positive appraisal of coercive measures. The emotional burden related to the use of coercion was associated with a more critical attitude.

Conclusions

The present results highlight the importance of considering staff members’ training and well-being regarding their feelings of insecurity when addressing attitudes towards coercion. The experience of patients should be integrated into staff training and coercion reduction programmes.

PURPOSE

Guidelines recommend germline genetic testing (GT) for patients with pancreatic ductal adenocarcinoma (PDAC). This study aims to evaluate the utilization and outcomes of multigene panel GT in patients with PDAC.

METHODS

This retrospective, multisite study included patients with PDAC diagnosed between May 2018 and August 2020 at Mayo Clinic Arizona, Florida, and Minnesota. Discussion, uptake, and outcomes of GT were compared before (May 1, 2018-May 1, 2019) and after (August 1, 2019-August 1, 2020) the guideline update, accounting for a transition period.

RESULTS

The study identified 533 patients with PDAC, with 321 (60.2%) preguideline and 212 (39.8%) postguideline. Patient characteristics did not differ between the preguideline and postguideline periods. GT was discussed in 34.3% (110 of 321) of preguideline and 39.6% (84 of 212) of postguideline patients (odds ratio [OR], 1.26 [95% CI, 0.88 to 1.80]) and subsequently performed in 80.9% (89 of 110) of preguideline and 75.0% (63 of 84) of postguideline patients (OR, 1.10 [95% CI, 0.75 to 1.61]). Of 152 tested patients, 26 (17.1%) had a pathogenic variant (PV), of whom 17 (11.2%; 17 of 152) were PDAC-associated. Over the entire study period, GT was more likely in younger patients (65 v 70 years; P < .001), those seen by a medical oncologist (82.9% v 69.0%; P < .001), and those surviving more than 12 months from diagnosis (70.4% v 43.4%; P < .001). Demographics and personal/family cancer history were comparable between patients with and without a PDAC PV.

CONCLUSION

GT remains underutilized despite National Comprehensive Cancer Network guideline recommendations. Given the poor prognosis of PDAC and potential implications of GT, efforts to increase utilization are needed to provide surveillance and support to both patients with PDAC and at-risk family members.

Published: April 2024

Context

Thyroid hormones are essential for energy metabolism related to thermogenesis and oxygen consumption.

Objective

This study evaluated the potential association of thyroid function including thyroid peroxidase antibodies (TPOAb) with physical activity in nationally representative data.

Design/Setting/Participants

This retrospective cohort study used data from the Korean National Health and Nutrition Examination Survey between 2013 and 2015. Physical activity (PA) was assessed using metabolic equivalents based on the validated Korean version of the International Physical Activity Questionnaire Short Form. PA level was categorized into 3 groups of high, moderate, and low. Participants with abnormal thyroid function test, restricted activity, or previous history of thyroid disease were excluded in the study.

Results

A total of 5372 participants was finally selected. The free T4 level was lowest in the low PA group, while TSH was not significantly different among the groups. TPOAb titers increased in the following order: moderate PA, low PA, and high PA. After adjustment for confounding factors, moderate PA was associated with a high T4 level and a decrease in TSH and TPOAb with significance. However, there were no significant changes in free T4, TSH, or TPOAb titer in the high PA group. In a subanalysis, females with moderate PA showed a significant decrease in TSH and TPOAb. In both males and females, insulin sensitivity was increased with moderate PA. In obese participants, TSH negatively correlated with PA, and free T4 levels decreased in the low PA. The sensitivity to thyroid hormone did not differ in our study.

Conclusion

The present study found an association between thyroid function and moderate PA. Therefore, moderate-intensity PA should be recommended to improve thyroid function.

Published: April 2024

Metformin-associated vitamin B12 deficiency is a well-established side effect, especially in patients taking higher doses of metformin or who have existing risk factors. Severe deficiency causes a wide range of systemic disorders. Gait instability, which leads to frequent falling, is usually an underrecognized side effect. Older patients are more likely to develop chronic subdural hematoma even with minor trauma. We present a case of 84-year-old man with type 2 diabetes mellitus with acute-on-chronic subdural hematoma from frequent falls. Metformin therapy at dose of 1700 mg/day was given for more than 25 years. He had been in his usual state of health until 10 months ago when he began to have frequent fallings and fatigue. Physical examination in this admission revealed new-onset impaired vibratory sensation and proprioception in both feet and positive Romberg test. Subsequent evaluations demonstrated undetectable plasma vitamin B12 level and elevated plasma homocysteine. Improvement in neurological symptoms occurred within 1 week of vitamin B12 replacement and surgical hematoma evacuation. This case highlights the importance of awareness and periodic monitoring of vitamin B12 status among older patients taking metformin.
Caspase-resistant ROCK1 expression prolongs survival of Eµ-Myc B cell lymphoma mice

Published: April 2024

Apoptosis is characterized by membrane blebbing and apoptotic body formation. Caspase cleavage of ROCK1 generates an active fragment that promotes actin–myosin-mediated contraction and membrane blebbing during apoptosis. Expression of caspase-resistant non-cleavable ROCK1 (Rock1 NC) prolonged survival of mice that rapidly develop B cell lymphomas due to Eµ-Myc transgene expression. Eµ-Myc; Rock1 NC mice had significantly fewer bone marrow cells relative to those in Eµ-Myc mice expressing wild-type ROCK1 (Rock1 WT), which was associated with altered cell cycle profiles. Circulating macrophage numbers were lower in Eµ-Myc; Rock1 NC mice, but there were higher levels of bone marrow macrophages, consistent with spontaneous cell death in Eµ-Myc; Rock1 NC mouse bone marrows being more inflammatory. Rock1 WT recipient mice transplanted with pre-neoplastic Eµ-Myc; Rock1 NC bone marrow cells survived longer than mice transplanted with Eµ-Myc; Rock1 WT cells, indicating that the survival benefit was intrinsic to the Eµ-Myc; Rock1 NC bone marrow cells. The results suggest that the apoptotic death of Eµ-Myc; Rock1 NC cells generates a proliferation-suppressive microenvironment in bone marrows that reduces cell numbers and prolongs B cell lymphoma mouse survival.

Preclinical and clinical studies on the administration of bone marrow-derived cells to restore perfusion show conflicting results. We conducted a systematic review and meta-analysis on preclinical studies to assess the efficacy of bone marrow-derived cells in the hind limb ischemia model and identify possible determinants of therapeutic efficacy. In vivo animal studies were identified using a systematic search in PubMed and EMBASE on 10 January 2022. 85 studies were included for systematic review and meta-analysis. Study characteristics and outcome data on relative perfusion were extracted. The pooled mean difference was estimated using a random effects model. Risk of bias was assessed for all included studies. We found a significant increase in perfusion in the affected limb after administration of bone marrow-derived cells compared to that in the control groups. However, there was a high heterogeneity between studies, which could not be explained. There was a high degree of incomplete reporting across studies. We therefore conclude that the current quality of preclinical research is insufficient (low certainty level as per GRADE assessment) to identify specific factors that might improve human clinical trials.
Η ποιμαντική διακονία και το φαινόμενο της εκκοσμίκευσης
Authors: Παπαντωνίου Νικόλας
Published: April 2024

Σκοπός της παρούσας διδακτορικής διατριβής είναι η μελέτη του φαινομένου της εκκοσμίκευσης σε σχέση με την ποιμαντική διακονία. Επισημαίνεται η ανάγκη μιας ορθής κατανόησης των προκλήσεων και των επιπτώσεων που προκύπτουν από την εξέλιξη του φαινομένου της εκκοσμίκευσης, το οποίο εξετάζεται ως κοινωνικό φαινόμενο, μέσα από μια κοινωνιολογική προσέγγιση, και ως εκκλησιαστικό φαινόμενο, μέσα από μια θεολογική προσέγγιση. Αναλύονται οι επιπτώσεις του φαινομένου της εκκοσμίκευσης στην εκκλησιαστική ζωή, τόσο στο επίπεδο της οργάνωσης της ενορίας όσο και στο επίπεδο της ατομικής θρησκευτικότητας, όπου εξετάζεται ειδικότερα η ύπαρξη της κατηγορίας των «κατ’ όνομα» χριστιανών. Υποστηρίζεται η απαραίτητη θεολογική θεμελίωση της ποιμαντικής με άξονα την ευχαριστιακή εκκλησιολογία ως προς την αντιμετώπιση των επιπτώσεων στο πλαίσιο της εκκοσμίκευσης. Επίσης εξετάζονται πτυχές και καταγράφονται προτάσεις για ένα πλαίσιο ποιμαντικής με στόχο την ανανέωση της εκκλησιαστικής ζωής. Στη συνέχεια προσεγγίζεται το πρόσωπο του ποιμένα και η διακονία του, όπου εξετάζονται οι προκλήσεις που υπάρχουν λόγω της εκκοσμίκευσης, τόσο ως κοινωνικό όσο και ως εκκλησιαστικό φαινόμενο. Η εκκοσμίκευση του ποιμένα σε ατομικό επίπεδο επισημαίνεται ως η βασικότερη πρόκληση σε σχέση με την ποιμαντική διακονία. Τονίζεται έτσι η καίρια σημασία της επιλογής, εκπαίδευσης και αξιολόγησης των ποιμένων για μια αποτελεσματική ποιμαντική διακονία στο πλαίσιο της εκκοσμίκευσης.
Το ρεύμα της φιλοσοφίας για παιδιά
Authors: Αναγνώστου Μαρία
Published: April 2024

Η παρούσα διδακτορική διατριβή μελετά τη δυνατότητα διδασκαλίας της φιλοσοφίας στην πρωτοβάθμια εκπαίδευση και συστηματικά ερευνά τους τρόπους με τους οποίους αυτό το εγχείρημα μπορεί να καταστεί γόνιμο για την ολιστική ανάπτυξη των παιδιών. Πραγματοποιείται αναφορά στις βασικές συνιστώσες και θεωρητικές καταβολές που συνέτειναν στη διαμόρφωση του ρεύματος της Φιλοσοφίας για παιδιά με σαφείς συνδέσεις με την παρακαταθήκη του σωκρατικού φιλοσοφικού προτύπου ζωής και σκέψης, τη συνδρομή του Πραγματισμού με επικέντρωση στον John Dewey, τη βιωματική μορφή της γλωσσικής επικοινωνίας της βιντγκενσταινικής σκέψης και τέλος την παιδαγωγική-ψυχολογική θέση του κοινωνικού κονστρουκτιβισμού του Lev Vygotsky για την ανάπτυξη της γλώσσας και τη σημασία των παιγνιωδών δραστηριοτήτων. Η εν λόγω πρόταση του Matthew Lipman είναι μια επί χάρτου ανακατασκευή του εγκύκλιου προγράμματος, μια συστηματική προσπάθεια παιδαγωγίας με φιλοσοφικό όραμα. Υποστηρίζεται δε, ότι η φιλοσοφική επένδυση της παιδαγωγικής πράξης οδηγεί στην καλλιέργεια της κριτικής και δημιουργικής σκέψης, στη συναισθηματική ανάπτυξη των παιδιών και στην ενδυνάμωση της κοινωνικής τους ταυτότητας. Η μελέτη αναδεικνύει την υπεροχή των διαθεματικών προγραμμάτων, τα οποία στηρίζονται στις αρχές της βιωματικής μάθησης, στον εμπλουτισμό τους με παιγνιώδεις δραστηριότητες στην αξία της συλλογικής διερεύνησης και στην αναγνώριση της πολλαπλότητας της ανθρώπινης νοημοσύνης. Η παιδαγωγική ευλυγισία, η κριτική συνειδητοποίηση της γνώσης και η σημασία της κοινωνικής συνέργειας χαρακτηρίζει τις παιδαγωγικές απόπειρες με φιλοσοφικό υπόβαθρο, όπου το παιδί θεωρείται ως αναστοχαστικός συμμετέχων και δημιουργός της παιδαγωγικής εμπειρίας. Η είσοδος της φιλοσοφίας στην πρωτοβάθμια εκπαίδευση δεν φιλοδοξεί να είναι η προσάρτηση ενός γνωστικού αντικειμένου, αλλά η συνθήκη για αλλαγή της σχολικής κουλτούρας. Η μελέτη επικεντρώνεται στη συμβολή της τέχνης και στους άξονες ωφέλειας της στα παιδιά σε γνωστικό, συναισθηματικό, κοινωνικό και ψυχολογικό επίπεδο με κομβική έννοια το ανθρώπινο σώμα στο παιγνιακό πλαίσιο, όπου το παιδί δρα με ασφάλεια και τελικά ανακαλύπτει τα αναδυόμενα νοήματα. Αναδεικνύονται σημεία σύγκλισης και διαλόγου ανάμεσα στη φιλοσοφία και την τέχνη, με βάση την αισθητική θεωρία του πραγματιστή φιλοσόφου, John Dewey, ο οποίος αντιμετώπιζε την τέχνη ως ανθρώπινη δραστηριότητα και εμπειρία νοηματοδότησης. Η διδακτορική διατριβή στο πρακτικό μέρος περιλαμβάνει διαθεματικά σχέδια εργασίας, τα οποία στηρίζονται στη σύμπραξη διαφορετικών γνωστικών αντικειμένων, μεθοδολογικά εμπνέονται από το ρεύμα φιλοσοφία για παιδιά, ενώ ταυτόχρονα συμπεριλαμβάνουν σύγχρονα παιδαγωγικά εργαλεία. Επικεντρώνονται στο τρίπτυχο: έρευνα-αναστοχασμός-δημιουργικότητα στο πλαίσιο κοινοτήτων μάθησης. Επιπρόσθετα αναπτύσσεται ένα προτεινόμενο ερευνητικό πρόγραμμα που θα αφορά στην εφαρμογή της φιλοσοφίας στην εκπαίδευση σε παιδιά σχολικής ηλικίας των δύο τελευταίων τάξεων και προτείνονται τα αντίστοιχα ερευνητικά εργαλεία του ενδεχόμενου πειραματικού εγχειρήματος.

Καθώς η ανταγωνιστικότητα εντατικοποιείται, οι επιχειρήσεις αναζητούν στρατηγικές για να παραμείνουν στην επιφάνεια. Μεταξύ άλλων, επιλέγουν προσεκτικά την τοποθεσία της δραστηριότητάς τους, προσλαμβάνουν ένα ταλαντούχο εργατικό δυναμικό και ασχολούνται με την καινοτομία. Σε αυτή τη διατριβή, εξετάζουμε αυτά τα τρία χαρακτηριστικά εμπειρικά, χρησιμοποιώντας κυρίως οικονομετρικές τεχνικές. Η συνεισφορά μας είναι στη βιβλιογραφία της ανταγωνιστικότητας των επιχειρήσεων, της βιομηχανικής οργάνωσης και της οικονομικής γεωγραφίας. Αρχικά, μελετάμε τις περιφερειακές ανισότητες στην παραγωγικότητα σε σχέση με με τα τοπικά πλεονεκτήματα αγοράς εφαρμόζοντας έναν αλγόριθμο μηχανικής μάθησης που ομαδοποιεί τα δεδομένα με βάση την πυκνότητα (density-based clustering) για να αναγνωρίσουμε τις ομάδες των επιχειρήσεων σε μια λεπτομερή γεωγραφική κλίμακα σε ένα δείγμα ιταλικών επιχειρήσεων. Στη συνέχεια, παρατηρούμε ταυτόχρονα το βαθμό με τον οποίο οι ομάδες εξηγούν τις οικονομίες συσσώρευσης (agglomeration economies) και τις επιδράσεις στη διαδικάσια εισόδου-εξόδου των επιχειρήσεων από την αγορά (firm selection). Τα ευρήματά μας υποδηλώνουν ότι οι πυκνές ομάδες δημιουργούν εξωτερικότητες λόγω συσσώρευσης οι οποίες είναι ανομοιογενείς ανά περιφέρεια. Στο δεύτερο μέρος της διατριβής, ερευνούμε την επίδραση των αλλοδαπών manager στην ανταγωνιστικότητα των επιχειρήσεων σε ένα δείγμα επιχειρήσεων που λειτουργούν στο Ηνωμένο Βασίλειο. Δείχνουμε ότι οι εγχώριες επιχειρήσεις γίνονται πιο αποδοτικές μετά την πρόσληψη αλλοδαπών στη διευθυντική τους ομάδα λόγω προηγούμενης εξειδικευμένης εμπειρίας στον ίδιο κλάδο. Στο τελευταίο μέρος, αξιολογούμε την επίδραση των διπλωμάτων ευρεσιτεχνίας στο μερίδιο αγοράς και στην παραγωγικότητα της εργασίας στον τομέα της Τεχνολογίας Πληροφορικής και Επικοινωνιών (ΤΠΕ) παγκόσμιως. Χρησιμοποιώντας ένα πρόσφατο difference-in-difference μοντέλο, διαπιστώνουμε ότι οι πατέντες αυξάνουν το μερίδιο αγοράς χωρίς να επηρεάζουν σημαντικά την παραγωγικότητα της εργασίας. Τα ευρήματά μας υποδηλώνουν κάποιες ανησυχίες σχετικά με τις επιπτώσεις των δικαιωμάτων ιδιοκτησίας από την καινοτομία στον ανταγωνισμό.

Gender and Anticommunism in Children’s Social Protection in Postwar Greece
Authors: Avdela Efi , Lampropoulou Dimitra
Published: April 2024

The article analyses the welfare activities provided by the Greek royal foundations in the period from their establishment in 1947 until 1968, focusing on their interventions concerning children and youth and their evolution over time. Placing the royal foundations’ activities in the Cold War and post-Civil War context, it argues that the intertwined state, parastatal and private initiatives, among which they had a hegemonic role, constituted the idiosyncratic Greek welfare state of the period, whose workings can be better grasped through the perspective of the mixed economy of welfare. Based on archival research, it highlights the gendered character of this specific version of welfare state-cum-mixed economy of welfare, and show that it was highly conservative, patriarchal and normative, based on ideological, political, class and gender exclusions. It depended on gendered massive voluntary action, especially women’s voluntary or low-paid work and elite women’s empowering activities.

Jerzy Maroń w wojsku
Authors: Jędrysiak Jacek , Szewczyk Radosław
Published: April 2024

The history of Jerzy Maroń’s military service in the ranks of the Polish People’s Army is a fascinating contribution to the internal history of this formation during the martial law. Professor Maroń, as a recent graduate of historical studies, underwent training in 1981 at the Reserve Officer Cadet School at the Center for Political Officers Training in Łódź, and then further training at the 1st Chemical Regiment in Zgorzelec. It was during this time that martial law was introduced. In response, the young cadet demonstratively renounced his party membership. This text provides, based on preserved archival materials, a broader context to the story known from the professor’s accounts, fully showcasing the uniqueness of his act.
„Der König rief, und alle, alle kamen”. Powstanie i organizacja Landwehry na Śląsku w 1813 roku
Authors: Malicki Patrycjusz
Published: April 2024

Napoleon’s defeat in 1812 marked the beginning of political changes in Europe that eventually led to the fall of the French emperor. Prussia played a significant role in this process. Humiliated by the Treaty of Tilsit (1807) and the Paris Convention (1808), Prussia became a state dependent on Paris. Forced by Napoleon’s dominance, Prussia participated in the 1812 campaign against Russia as part of the X Corps of the Grand Army, fighting on the left wing of Napoleon’s forces. Due to Prussia’s participation in the war against Russia, the hidden reserve training system (the so-called Krümpersystem), and royal orders from January and February 1813 aimed at strengthening the numerical strength of the army (including the creation of third battalions in regiments or reserve battalions), much larger forces were available than Napoleon’s will allowed. To enhance the effort of creating new formations and reduce state expenses, the monarchy also appealed to the patriotism of its subjects.

Despite the fact that the iconography of seals has long been of interest to military historians and outfit researchers, it mainly concerns royal seals, unquestionably the most impressive category. Indeed, thanks to the detailed depictions of armament and attires on the oldest seals, it was possible to discover many interesting facts. The seals used by knights constitute an object of interest for sigillography, primarily as a source for heraldic research and, in connection with the documents associated with them, studies in the fields of diplomatics and genealogy. The aim of this article is to review the depictions of armament present on the oldest knightly seals preserved in the State Archive in Wrocław and to analyze the usefulness of this category of sources in research on the history of medieval weaponry.
Der Dune-Hort in neuem Licht?
Authors: Sachs Rainer
Published: April 2024

The Dune Treasure from Gotland is one of the largest treasures of medieval Scandinavia. It is believed to have been hidden in 1361. To this day, the find has not been adequately studied in terms of its significance. The most famous element of the treasure is a buckle depicting a rider, his squire, and a female figure in front of them. The meaning of this representation has not been definitively established. Another ornament by the same buckle’s maker is stored at the Metropolitan Museum in New York. The iconography of the buckle is based on an initial in the manuscript Clm. 14055 from the Bavarian State Library in Munich. The graphic pattern of the scene on the buckle is found in the codex Clm 13002 of the same library. The history of the prototypes of the jewels suggests that they may have been created only in the 19th century. The authors of the buckle itself are Dr. Franz Bock (1823-1899, intellectual concept), director of the Cologne Diocesan Museum, and Reinhold Vasters (1827-1909, execution of the ornament), a goldsmith from Aachen. It seems probable that the initiator of depositing the treasure was the king of Sweden and Norway, Oscar II (1829-1907).

LVIV HOSTAGES IN OTTOMAN CAPTIVITY, 1672-1679

After capturing Kamieniec Podolski [Kamianets-Podilskyi] in late August 1672, Ottoman army moved towards Lwów [Lviv] and started its siege in September. The condition for withdrawing from the siege was a ransom of eighty thousandtalers. Only five thousand was collected, and the missing amount was compensated by agreeing to hand over eleven hostages, including two Armenians. Later efforts resulted in the release of the Armenian hostages in 1676, while the remaining ones were released only in 1679. The author attempts to organize the topic of Lwów hostages, frequently mentioned in source materials but scattered and containing many contradictions, especially regarding their names and fate.

Es esencial reconocer que, en un país como Colombia, la diversidad geográfica, étnica y cultural contribuye a la formación de variados significados. La educación rural se nutre de distintos procesos socioculturales y solo puede ser entendida considerando su singularidad, su historia y la variedad de contextos y relaciones en los territorios.
Odmítnutí podání znaleckého posudku
Authors: Ševčík Petr
Published: April 2024

Dne 1. 1. 2021 vstoupil v účinnost nový zákon č. 254/2019 Sb., o znalcích, znaleckých kancelářích a znaleckých ústavech (dále jen „ZnalZ“), který nahradil dřívější právní úpravu zákona č. 36/1967 Sb., o znalcích a tlumočnících, ve znění pozdějších předpisů (dále jen „ZnalZ1967“). S příchodem každé nové právní úpravy je spojeno období určité nejistoty, kdy se vzájemně nově vymezují v aplikační praxi práva a povinnosti zúčastněných subjektů. A právě oblast odmítnutí znaleckého úkonu je s ohledem na zcela rozličné zájmy zadavatelů znaleckých posudků a znalců samotných nanejvýš významná. Předkládaný článek by měl čtenáři přiblížit novou právní úpravu odmítnutí podání znaleckého úkonu tak, jak ji nově definuje § 19 ZnalZ. Pro lepší přehlednost je vždy uvedeno i srovnání konkrétní komentované části s historickou právní úpravou, případně je uvedeno, že historická analogie není. Řešena je detailně i otázka „akceptace či neakceptace“ důvodů pro odmítnutí podání znaleckého úkonu, a to i ve srovnání se slovenskou právní úpravou, která byla v mnoha oblastech legislativním vzorem nové české právní úpravy.

Předkládaný článek využívá a hlouběji rozpracovává závěry autora uvedené v komentáři k § 19 in ŠEVČÍK, Petr, MALAST, Jan, POLÁČEK, Bohumil a kol. Zákon o znalcích, znaleckých kancelářích a znaleckých ústavech. Praktický komentář. Praha: Wolters Kluwer ČR, 2023.
The Innovative Development of Digital Public Capital under the Conditions of Socialism with Chinese Characteristics
Authors: Zhao Xiuli , Gao Xiaojie , Yang Yang
Published: April 2024

Operating through digital platforms, the digital economy has flourished, becoming the core driver and new motive force of economic growth and demonstrating its advantages in terms of scale, effectiveness, and penetration. Nevertheless, the digital economy, as an important element in the socialist market economy with Chinese characteristics, remains dominated by private capital, and this has caused many problems. The government of China proposes not only to prevent the disorderly expansion of capital, but also to use the role of capital as an important factor of production in the market economy and a means of subjecting capital to a system of “traffic lights.” In this context, the article starts out from the theoretical logic of the dual nature of capital and of the “tension” created by the inherent contradictions of digital capital and the practical logic of the “gravitational force” exerted by the mega-size of the socialist market economy with Chinese characteristics. The article then expounds on the historical inevitability of the emergence of digital public capital, and systematically sets out the compositional map of the pluralistic digital capital system dominated by digital public capital and developed together with digital non-public capital. Finally, and on this basis, it draws conclusions and makes policy recommendations.
The digital governmentality of marriage migration: policing US spousal reunification, national belonging and borders in digital spaces
Authors: Longo Gina Marie , Turowetz Jason
Published: April 2024

There is extensive research on the governmentality of marriage migration, but more is needed about the role of digital spaces. This article focuses on how online US spousal reunification forums and their users define and police ideological norms regarding the US family and decide which transnational relationships are ‘worthy’ of immigration. We show that through their interactions on the site, users perform borderwork and police family, race and nation. More generally, we argue that online forums constitute institutional settings whose members can reproduce or challenge hegemonic state discourses about ‘proper’ families and national belonging. Further, we suggest that advice given to or withheld from forum participants constitutes an exercise in digital governmentality. Overall, our findings contribute to conversations about the role digital spaces play in institutionalising gatekeeping practices intended to police intimacy, immigration and national belonging.

Authors: Oliinyk Oksana , Oliinyk Anna
Published: April 2024

In the wake of war and displacement, families like Oksana’s and Anna’s have found solace and connection through the use of digital technology. This article explores the experiences of Oksana and Anna, a Ukrainian woman aged 51 and her 23-year-old daughter who currently live in Edinburgh, separated from Oksana’s husband (Anna’s father), extended family and friends due to the war in Ukraine. Through a narrative lens, Oksana shares her reliance on communication tools such as Telegram, WhatsApp, and Facetime to bridge the physical distance between loved ones. The family’s daily rituals, from shared dinners over video calls to collaborative board games, highlight the importance of maintaining familial bonds amidst adversity. Additionally, the article sheds light on the broader societal context, comparing the prevalence of digital communication practices in Ukraine versus Scotland. The narrative also touches upon the profound impact of technology on healthcare management, particularly in supporting Maria, Oksana’s daughter, who battles diabetes. Lastly, Anna reflects on the emotional complexities of maintaining family ties amidst war, emphasizing the significance of technology in preserving connection and providing a lifeline to loved ones in times of distress. Through stories about air raid alerts and family group chats, Anna underscores the resilience and adaptability of Ukrainian families facing adversity.
Modeling single cell trajectory using forward-backward stochastic differential equations
Authors: Zhang Kevin , Zhu Junhao , Kong Dehan , Zhang Zhaolei
Published: April 2024

Recent advances in single-cell sequencing technology have provided opportunities for mathematical modeling of dynamic developmental processes at the single-cell level, such as inferring developmental trajectories. Optimal transport has emerged as a promising theoretical framework for this task by computing pairings between cells from different time points. However, optimal transport methods have limitations in capturing nonlinear trajectories, as they are static and can only infer linear paths between endpoints. In contrast, stochastic differential equations (SDEs) offer a dynamic and flexible approach that can model non-linear trajectories, including the shape of the path. Nevertheless, existing SDE methods often rely on numerical approximations that can lead to inaccurate inferences, deviating from true trajectories. To address this challenge, we propose a novel approach combining forward-backward stochastic differential equations (FBSDE) with a refined approximation procedure. Our FBSDE model integrates the forward and backward movements of two SDEs in time, aiming to capture the underlying dynamics of single-cell developmental trajectories. Through comprehensive benchmarking on multiple scRNA-seq datasets, we demonstrate the superior performance of FBSDE compared to other methods, highlighting its efficacy in accurately inferring developmental trajectories.
Representing the Unrepresentable
Authors: Dridi Yosr
Published: April 2024

This article discusses the representations of alienhood in a selection of first contact science-fiction films. It performs a cinematographic reading of human encounters with and attitudes towards alienhood. By examining the visual stylistic choices, the representation of outer-space (other)worlds and alienhood will be problematized beyond the binarism of vilification and celebration. Instead, contact with alienhood will offer deeper insight into the cultural, intellectual and psychological facets of human identity and urge further introspection about the human position in a universe that no longer obeys an anthropocentric logic. Ultimately, first contact science-fiction cinema will be shown to relativize the reassuring conception of selfhood and to suggest the obsolescence of universalist-humanist assumptions about alienhood. This is achieved by opting for a representational one-way route which leads towards acceptance, not of the alien per se, but of the potential and limits of the human self when faced with the unknowability and the unrepresentability of alienhood.
Relationship of Neighborhood Resources Utilized and the Impact on Academic Achievement in the Children of Housing Choice Voucher Participants
Authors: Kelly Damien
Published: April 2024

Housing Choice Vouchers have expanded housing opportunities for millions of low-income households throughout the United States. Vouchers provide low-income households the opportunity to move to different neighborhoods. A growing body of research has shown where a household resides has a large impact on both economic outcomes, and the quality of their children’s education. This is the second of a three-part research project which explored the effect neighborhood choice has on the academic achievement of Housing Choice Voucher participant’s high school aged children. Using survey data, this study explored the relationship, utilizing neighborhood resources had on passing STAAR reading and mathematics exam. Of the 4,884 flyers mailed to households utilizing the Housing Choice Voucher, 77 participants used the QR code to access the questionnaire with 51 participants completing the questionnaire with the required information. Findings were analyzed using Pearson’s Chi-square and frequency distributions. Findings suggest the utilization of police had a correlation to passing the STAAR reading exam and though a larger percentage of households utilize the resource of tutoring, it did not correlate to the passing of the STAAR mathematics exam.

Published: April 2024

Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disorder that affects individuals across all age groups, including children, adolescents, and adults. The etiology of ADHD involves lack of a number of nutrients and food components. However, certain dietary strategies have been suggested as additional therapy in this condition. This review shed light on the correlation of dietary patterns with ADHD and to provide a concise summary of the current research about the practical application of dietary therapies. In the research, unhealthy eating habits were positively correlated with ADHD, but healthy eating habits were negatively correlated. Furthermore, there is a notable correlation between ADHD and a lack of certain nutrients, including iron, zinc, magnesium, polyunsaturated fatty acids (PUFAs) and vitamin D. These dietary modifications are promising strategies for ADHD management and needs stronger scientific proof to be validated.
Unsettled hearing, responsible listening. Encounters with voice after forced migration
Authors: Brizić Katharina
Published: April 2024

In line with increasing forced migrations around the globe, there is also a growing need for ethical encounters between researchers and those forcefully displaced. This article focuses on responsible Listening, defined as the ethically motivated effort of researchers to conduct communication at eye level. However, findings have shown that listeners (e.g., researchers in institution or study settings) may already feel unsettled on the far more basic level of hearing a human voice, if certain implicit (e.g., aesthetic) expectations are not met. This makes encounters particularly vulnerable after forced migration where voices tend to be easily silenced. I will show by means of an empirical example what hearing a voice in its materiality, i.e. intonation, rhythm, accentuation etc., can set off, and how a privileged space of Listening to the Other can emerge.
Potential medical impact of unrecognized in vitro hypokalemia due to hemolysis: a case series
Authors: Wu Alan H.B. , Peacock W. Franklin
Published: April 2024

Objectives

The destruction of red cells during blood collection or with the processing of the sample continues to occur at a high rate, especially among emergency department (ED) patients. This can produce pre-analytical laboratory errors, particularly for potassium. We determined the incidence of hemolyzed samples and discuss the potential medical impact for hypokalemic patients who potassium level is artificially normal (pseudoeukalemia).

Methods

Potassium results were obtained for a 6-month period. Using a measured hemolysis index (HI), hemolysis was present in 3.1 % for all potassium ordered (n=94,783) and 7.5 % for ED orders (n=22,770). Most of these samples were reported as having high normal result or were hyperkalemic. There were 22 hemolytic samples with a potassium of <3.5 mmol/L, and 57 hemolytic samples with a potassium in lower limit of normal (3.5–3.8 mmol/L). From this group, we examined the medical histories of 8 selected patients whose initially normal potassium levels were subsequently confirmed to have a potassium values that were below, at, or just above the lower limit of normal due to hemolysis.

Results

The primary complaint for these patients were: necrotizing soft tissue infection, pancreatitis, volume overload from heart failure with reduced ejection fraction, hypertension treated with hydrochlorothiazide, and presence of a short bowel syndrome. A subsequent non-hemolyzed sample was collected demonstrating hypokalemia in all of these patients. Within these cases, there was a potential for harm had hemolysis detection not been performed.

Conclusions

We demonstrate the medical importance of detecting hemolysis for patients who have pseudoeukalemia. This is relevant because the HI cannot be obtained when electrolytes are tested using whole blood samples, and a normal potassium may lead to inappropriate patient management.
Multi-stage voltage sag frequency evaluation based on process immunity in the distribution network
Authors: Ma Li , Zhang Yanhu , Chen Yingyu , Li Yu , Lou Jinghui , Liu Xin , Li Zirui
Published: April 2024

The reclosing action of the distribution network may cause multi-stage voltage sag in the grid nodes, which leads to more serious losses for sensitive users. In order to more reasonably characterize the disturbance degree of multi-stage voltage sag on sensitive equipment, a frequency evaluation method based on process immune time (PIT) and improved analytic hierarchy process is proposed. Firstly, multi-stage voltage sag waveforms caused by the reclosing corresponding action under transient fault and permanent fault are analyzed, and the PIT characteristic curve of sensitive equipment under multi-stage voltage sag is characterized. Secondly, the weight function method is used to calculate the influence degree of each stage sag. The analytic hierarchy process is improved by utilizing the correlation and influence degree of each stage sag. The weight of each stage sag is determined, and then the amplitude of the multi-stage voltage sag is calculated equivalently. The multi-stage voltage sag frequency evaluation method is proposed in the distribution network. Finally, the IEEE 30-bus system is used for simulation verification. The results show that the proposed method is more accurate and reasonable for the evaluation of multi-stage voltage sag frequency. This method provides a basis for the frequency evaluation and governance of multi-stage voltage sag.
Performance analysis of variable-gain amplify and forward relayed hybrid FSO/VLC communication system
Authors: Sharma Kamna , Aggarwal Mona , Sabherwal Pooja
Published: April 2024

In this paper, we consider a hybrid free space optics/visible light communication (FSO/VLC) system having three nodes, where there is no line of sight communication possible between the source node and the destination node and the communication between these two nodes take place with the help of an amplify and forward relay which acts as an intermediate node. The source to relay link is an FSO link modelled by Gamma–Gamma fading distributions and the relay to destination is considered as VLC link. We derive the statistical characteristics of system signal to noise ratio at the destination in terms of moment generating function, closed form expression of end to end outage probability as well as bit error probability of the proposed hybrid system. Furthermore, we analyzed the effect of varying various parameters of both the links, on outage probability as well as on bit error probability of the proposed system.
