Ayahuasca is a blend of Amazonian plants that has been used for traditional medicine by the inhabitants of this region for hundreds of years. Furthermore, this plant has been demonstrated to be a viable therapy for a variety of neurological and mental diseases. EEG experiments have found specific brain regions that changed significantly due to ayahuasca. Here, we used an EEG dataset to investigate the ability to automatically detect changes in brain activity using machine learning and complex networks. Machine learning was applied at three different levels of data abstraction: (A) the raw EEG time series, (B) the correlation of the EEG time series, and (C) the complex network measures calculated from (B). Further, at the abstraction level of (C), we developed new measures of complex networks relating to community detection. As a result, the machine learning method was able to automatically detect changes in brain activity, with case (B) showing the highest accuracy (92%), followed by (A) (88%) and (C) (83%), indicating that connectivity changes between brain regions are more important for the detection of ayahuasca. The most activated areas were the frontal and temporal lobe, which is consistent with the literature. F3 and PO4 were the most important brain connections, a significant new discovery for psychedelic literature. This connection may point to a cognitive process akin to face recognition in individuals during ayahuasca-mediated visual hallucinations. Furthermore, closeness centrality and assortativity were the most important complex network measures. These two measures are also associated with diseases such as Alzheimer’s disease, indicating a possible therapeutic mechanism. Moreover, the new measures were crucial to the predictive model and suggested larger brain communities associated with the use of ayahuasca. This suggests that the dissemination of information in functional brain networks is slower when this drug is present. Overall, our methodology was able to automatically detect changes in brain activity during ayahuasca consumption and interpret how these psychedelics alter brain networks, as well as provide insights into their mechanisms of action.
“Once you get cancer you die. There is no way to get saved from cancer.” A qualitative exploration of patients’ perceptions towards cancer in Fiji
Authors: Kumar Kaushal , Mohammadnezhad Masoud
Published: December 2022

Background

Understanding patients’ perspective to get an insight into cancer, and how best the public health systems can battle with this disease is the way forward in this current world. This study aimed to explore patients’ knowledge about common cancers, barriers to assessing cancer information and cancer preventative approaches in Fiji.

Methods

The study used a qualitative method approach that was conducted among patients who attended Special Outpatients (SOPD) at the four selected health centres in Lautoka Subdivision, Fiji from 1st March to 30th April 2021. A semi-structured open-ended questionnaire was used to guide in-depth interviews. These audio recordings were transcribed and analysed using thematic analysis. All interview transcripts were read and similar words and phrases were assigned numbers which were grouped together to identify themes and sub themes.

Results

Twenty-eight patients took part in the in-depth interview and the responses were grouped into four themes including; cancer knowledge, diagnosis of cancer in a close friend/family, barriers of communication and optimizing cancer awareness. Patients’ awareness about common cancers and cancer risk factors was low. Many barriers for cancer screening were highlighted including stigmatization, fear, worry, death, lack of information, herbal medicine use, lack of resources and delay in diagnosis. Awareness strategies highlighted by participants included community outreach programs, house to house visits, opportunistic screening, engagement of community health care workers and the concept of a cancer hub centre.

Conclusion

It is evident that there is a range of views from patients towards cancer and it is important to understand these perceptions to better guide public health interventions concerning cancer. This puts more focus on the need to invest more in information, education, and communication material for public campaigns that target a variety of people for a wider reach.
Identification of inverse kinematic parameters in redundant systems: Towards quantification of inter-joint coordination in the human upper extremity
Authors: Khoramshahi Mahdi , Roby-Brami Agnes , Parry Ross , Jarrassé Nathanaël
Published: December 2022

Understanding and quantifying inter-joint coordination is valuable in several domains such as neurorehabilitation, robot-assisted therapy, robotic prosthetic arms, and control of supernumerary arms. Inter-joint coordination is often understood as a consistent spatiotemporal relation among kinematically redundant joints performing functional and goal-oriented movements. However, most approaches in the literature to investigate inter-joint coordination are limited to analysis of the end-point trajectory or correlation analysis of the joint rotations without considering the underlying task; e.g., creating a desirable hand movement toward a goal as in reaching motions. This work goes beyond this limitation by taking a model-based approach to quantifying inter-joint coordination. More specifically, we use the weighted pseudo-inverse of the Jacobian matrix and its associated null-space to explain the human kinematics in reaching tasks. We propose a novel algorithm to estimate such Inverse Kinematics weights from observed kinematic data. These estimated weights serve as a quantification for spatial inter-joint coordination; i.e., how costly a redundant joint is in its contribution to creating an end-effector velocity. We apply our estimation algorithm to datasets obtained from two different experiments. In the first experiment, the estimated Inverse Kinematics weights pinpoint how individuals change their Inverse Kinematics strategy when exposed to the viscous field wearing an exoskeleton. The second experiment shows how the resulting Inverse Kinematics weights can quantify a robotic prosthetic arm’s contribution (or the level of assistance).

Published: December 2022

Background

Sickle cell anemia (SCA) is a monogenic hemoglobinopathy associated with severe acute and chronic complications, with the highest incidence worldwide in Sub-Saharan Africa. The wide variability in clinical manifestations suggest that a uniform response to hydroxurea may not be attained. In view of a potential treatment with hydroxyurea (HU), we assessed the variability of clinical and hematological manifestations in a cohort of adults with SCA in Kinshasa, capital of the DR Congo in Central Africa.

Methods

A cross-sectional study was conducted in a hospital dedicated to SCA management in Kinshasa. Clinical history of patients was recorded, a complete physical examination performed. The diagnosis was confirmed by means of DNA analysis. A full blood count and hemolysis markers were measured. The severity of the disease was evaluated by means of a previously reported score.

Results

The study group consisted of 166 genetically confirmed SCA patients. The SCA severity was mild in 28.9%, moderate in 64.5% and severe in 6.6%. The disease severity score increased with patient’s age (p ≤ 0.001). The severity was higher in males compared to females (p = 0.012). In males, the severity score was correlated with the presence of priapism (p = 0.045), a manifestation not previously incorporated in the severity score. The severity score was inversely correlated with the fetal hemoglobin (HbF) rate (p = 0.005). Malnutrition (BMI <18.5 kg/m2) was present in 47% of patients and was related to the male sex, hip disease (aOR 3.11; p = 0.019) and severe phenotype (aOR 3.53; p = 0.012). Leg ulcers were more frequent in males than in females (p = 0.001; OR 24.3) and were correlated with the number of days of hospitalization (p = 0.029). Hip disease was related to the increasing age (p = 0.008).

Conclusion

In this selected, hospital-based populations of adults with SCA, severe disease was rare, which may be due to survival bias. However, two thirds had moderate severity of the disease, mostly with a low HbF, and they may benefit from HU treatment. In the Central-African setting the separation between vaso-occlusive and hyperhemolytic sub-phenotypes was not applicable.

Published: December 2022

Background

Numbers of urgent short stay admissions (SSAs) of children to UK hospitals are rising rapidly. This paper reports on experiences of SSAs from the perspective of parents accessing urgent care for their acutely unwell child and of health professionals referring, caring for, or admitting children.

Methods

A qualitative interview study was conducted by a multi-disciplinary team with patient and public involvement (PPI) to explore contextual factors relating to SSAs and better understand pre-hospital urgent care pathways. Purposive sampling of Health Board areas in Scotland, health professionals with experience of paediatric urgent care pathways and parents with experience of a SSA for their acutely unwell child was undertaken to ensure maximal variation in characteristics such as deprivation, urban-rural and hospital structure. Interviews took place between Dec 2019 and Mar 2021 and thematic framework analysis was applied.

Results

Twenty-one parents and forty-eight health professionals were interviewed. In the context of an urgent SSA, the themes were centred around shared outcomes of care that matter. The main outcome which was common to both parents and health professionals was the importance of preserving the child’s safety. Additional shared outcomes by parents and health professionals were a desire to reduce worries and uncertainty about the illness trajectory, and provide reassurance with sufficient time, space and personnel to undertake a period of skilled observation to assess and manage the acutely unwell child. Parents wanted easy access to urgent care and, preferably, with input from paediatric-trained staff. Healthcare professionals considered that it was important to reduce the number of children admitted to hospital where safe and appropriate to do so.

Conclusions

The shared outcomes of care between parents and health professionals emphasises the potential merit of adopting a partnership approach in identifying, developing and testing interventions to improve the acceptability, safety, efficiency, and cost-effectiveness of urgent care pathways between home and hospital.
Facts and fears that limit digital transformation in farming: Exploring barriers to the outreach of wireless sensor networks in Southwest Iran
Authors: Taheri Fatemeh , D’Haese Marijke , Fiems Dieter , Azadi Hossein
Published: December 2022

Wireless sensor networks (WSNs) are considered part of an environmentally friendly technology leading to more timely and cost-effective production and management of farms. Despite the potential of WSNs to agricultural development in the global South, outreach is still very limited, also in Iran. Therefore, in order to facilitate the adoption of WSNs, it is necessary to identify the factors influencing and challenging the adoption of this technology. This exploratory study uses a qualitative approach to identify the main barriers WSN outreach is facing. In the results, we distinguish facts that we define as issues or barriers that were identified by others from fears that are not supported by evidence so far, at the level of the farmers, the government actors as well as the technology itself. Facts include communication barriers such as internet access, farmers’ knowledge levels and rigidity to change as well as the government’s top-down organisation of the extension programme and support levels. Fears are mainly expressed on the technology itself and relate to costs, a lack of access, the complexity of use and reliability of the data. We provide a nuanced view of how fears need to be acknowledged and facts are to be tackled.
Habitat suitability and connectivity modeling predict genetic population structure and priority control areas for invasive nutria (Myocastor coypus) in a temperate river basin
Authors: Kang Wanmo , Kim GoWoon , Park Yongsu
Published: December 2022

The nutria (Myocastor coypus), also known as the coypu, is a semi-aquatic, invasive rodent native to South America that causes damage to natural riverine and wetland habitats in many parts of the world, including South Korea. Understanding habitat use, connectivity, and gene flow of nutria populations is critical for the sound management of local and regional ecosystems. Here, we assessed habitat suitability and connectivity in relation to the genetic structure of nutria populations in the Nakdong River Basin of South Korea. A total of 321 nutria occurrence sites and seven environmental variables were used to perform ensemble habitat suitability modeling using five species distribution models (SDMs), including boosted regression trees, maximum entropy model, random forest, generalized linear model, and multivariate adaptive regression splines. Using graph and circuit theory approaches, we assessed the population gene flow and current flow betweenness centrality (CFBC) of suitable habitats derived from the ensemble SDM. All SDMs performed well with a range of test AUC values from 0.962 to 0.970 (mean = 0.966) with true skill statistic values over 0.8. The minimum temperature of the coldest month, mean temperature of the warmest quarter, precipitation of the driest quarter, and distance from water bodies were important predictors in nutria habitat modeling. Nutria population gene flow was significantly correlated with the least-cost path distance on a cost resistance surface based on ensemble habitat suitability modeling and roads (Mantel’sr= 0.60,p< 0.05). Finally, the CFBC positively correlated with the genetic diversity of nutria populations was used to identify priority control areas. Habitat suitability and connectivity modeling not only revealed environmental conditions and areas that support the survival and spread of nutrias, but also improved our understanding of the animals’ genetic population structure, thereby indicating priority areas to target for eradication.
The impact of augmented feedback (and technology) on learning and teaching cricket skill: A systematic review with meta-analysis
Authors: Tissera Kevin , Orth Dominic , Huynh Minh , Benson Amanda C.
Published: December 2022

Augmented feedback, including that provided using technology, can elicit multifaceted benefits on perceptual-motor learning and performance of sporting skills. However, current considerations of the applied value in supporting learning and teaching cricket skill is limited. This systematic review with meta-analysis aimed to understand the role and effectiveness of feedback-involved interventions on skill-based performance outcomes in cricket-related research. Six electronic databases were searched (SPORTDiscus, CINAHL, MEDLINE, Scopus, Web of Science and PsycINFO). Of 8,262 records identified, 11 studies met inclusion criteria; five of which were included in meta-analyses. Given no studies with an isolated feedback intervention-arm were identified, the two meta-analyses explored anticipation-based studies consisting of an intervention that included augmented feedback; positioned with respect to the key motor skill concepts of perception (anticipation accuracy) and action (performance success). Despite results highlighting improved performance outcomes for the feedback-involved intervention groups, with a large effect size for improved anticipation accuracy (Hedge’s g = 1.21, 95% CIs [-0.37, 2.78]) and a medium effect size for overall performance success (Hedge’s g = 0.55, 95% CIs [-0.39, 1.50]), results were not statistically significant and should be interpreted with caution given the wide confidence intervals. Considering the small number of studies available, in addition to the lack of isolated feedback protocols, further research is warranted to thoroughly explore the impact of augmented feedback on skill-based performance in cricket. Beyond the meta-analyses, the review also explored all included studies from an ecological dynamics perspective; presenting future avenues of research framed around evaluating the applied value of using augmented feedback (mediated with or without technology) for learning and teaching skill in cricket.

Published: December 2022

Introduction

Quality of life in prostate cancer survivorship is becoming increasingly important, with mental and social wellbeing recognised as key components. However, limited global evaluation of psychosocial challenges experienced after treatment exists. Therefore, we aimed to explore the lived experiences of men who underwent radical treatment, and its psychosocial impact.

Material and methods

This qualitative study was conducted using 19 men who had undergone radical treatment (prostatectomy or radiotherapy) for their cancer. Semi-structured interviews were conducted exploring lived experiences of men after treatment. A Structured thematic analysis of collected data was undertaken, with an inductive co-construction of themes through the lens of the biopsychosocial model. Themes generated were considered within a psychological, social, and physical wellbeing framework.

Results

An initial knowledge gap meant mental wellbeing was strongly impacted initially leading to a ‘Diagnostic Blow and the Search for Clarity’. Doubt over individuals’ future resulted in ‘An Uncertain Future’ in many men. Once treatment was completed a ‘Reflective journey’ began, with men considering their outcomes and decisions made. Social wellbeing was also impacted with many identifying the ‘Emotional Repercussions’ on their relationships and the impact their diagnosis had on their partner and family. Many subsequently sought to increase their support through ‘The Social Network and Advocacy’, while physical changes led to an increased need for ‘Social Planning’. Finally, physical wellbeing was highlighted by a continual acknowledgement of the ‘Natural process of ageing’ leading to a reluctancy to seek help, whilst simultaneously attempting to improve existing health via ‘The Health Kick’.

Conclusions

Radical treatments have a considerable impact on mental and social wellbeing of individuals. Anxiety after diagnosis and significant uncertainty over individual futures exist, with physical complications of treatment leading to social repercussions. Future research should aim to identify forms of support to improve quality of life of these men.
Teaching lessons learnt by civil-engineering teachers from the COVID-19 pandemic at the University of Burgos, Spain
Authors: Revilla-Cuesta Víctor , Skaf Marta , Espinosa Ana B. , Ortega-López Vanesa
Published: December 2022

The COVID-19 lockdown in Spain caused abrupt changes for students following the Bachelor’s Degree in Civil Engineering at the University of Burgos when face-to-face classes switched to online teaching. The recovery of face-to-face teaching after lockdown meant that classes were taught with obligatory social distancing and the use of masks. Teachers were therefore unable to interact with students closely, to perceive their facial expressions during class, or to conduct group work. The changes to civil-engineering teaching linked to the COVID-19 pandemic and the lessons that civil-engineering teachers learnt from the new teaching scenarios are studied in this paper. The reflections of teachers throughout all three stages of the pandemic (pre-pandemic and lockdown, during lockdown, and post-lockdown), and the qualitative and mixed analysis of their responses to a survey of open-ended questions contributed to the identification of six major lessons: (1) asking questions and using real-time quiz tools enliven classes and help to determine which concepts to emphasize for proper student understanding; (2) autonomous student learning can be promoted through the provision of supplementary documentation and the digitalization of solutions to classroom exercises; (3) virtual site visits and real visual examples interspersed with explanations bring concepts closer to their real applications; (4) the delivery of projects in the form of audio-recorded presentations enable their distribution, so that other students can also learn from them as well as the students who created them; (5) online videoconferences, adapted to the concepts that are addressed, facilitate fast and flexible communication with students; and (6) online continuous-assessment exams can promote better student learning patterns and final-exam preparation. Nevertheless, these six lessons were drawn from the experience of teachers at a small Spanish university where the period of solely online teaching during the COVID-19 pandemic lasted only four months. Thus, it would be interesting to analyze the experience of civil-engineering teachers at larger universities and universities that had longer periods of solely online teaching. A study of the level of implementation of the six aspects when the pandemic is declared over might also be worthwhile.
Farm production diversity, household dietary diversity, and nutrition: Evidence from Uganda’s national panel survey

Published: December 2022

Improved food security and nutrition remain a notable global challenge. Yet, food security and nutrition are areas of strategic importance regarding the United Nations’ Sustainable Development Goals. The increasingly weakening global food production systems pose a threat to sustainable improved food security and nutrition. Consequently, a significant population remains chronically hungry and severely malnourished. As a remedy, farm production diversity (FPD) remains a viable pathway through which household nutrition can be improved. However, evidence is mixed, or unavailable on how FPD is associated with key nutrition indicators like household dietary diversity, energy, iron, zinc, and vitamin A (micronutrients). We use the Uganda National Panel Survey (UNPS) data for rural households to analyze differential associations of sub-components of FPD on dietary diversity, energy, and micronutrient intake. Panel data models reveal that indeed crop species count, and animal species count (sub-components of FPD) are differently associated with household dietary diversity score (HDDS), energy, and vitamin A sourced from markets. Moreover, when volumes of these nutrition outcomes were disaggregated by source (own farm vs. markets), the animal species count was only positively significantly associated with nutrition outcomes sourced from consumption of produce from own farm. Associations were insignificant for nutrition indicators sourced from markets except vitamin A. The crop species count, however, consistently showed a strong positive and significant association with energy, and all studied micronutrients sourced from own farm produce consumption, as well as those sourced from markets except Vitamin A, which was negative but insignificant. Therefore, inclusive, pro-poor, and pro-nutrition rural policy initiatives in the context of rural Uganda and similar ones, could more widely improve household nutrition through prioritizing crop species diversification on own farms because crops fetch wider nutrition gains.

Tabako-ohiturak gaixotasun kroniko gehienak pairatzeko arriskua areagotu dezakeen ohitura zabaldua da. Haien artean, hipertentsioaren eragilea izan daitekeela behatu da. Horrez gain, jarduera fisikoarekiko (JF) tolerantzian eta bihotz-biriketako funtzioan eragin kaltegarria izan dezake. Izan ere, JF-ak arrisku hauen garapena murriztu ditzake, eta bihotz-birika gaitasunean (BBG) hobekuntzak eragin. Hortaz, ikerketa honen helburua da hipertentsioa, gehiegizko pisua, bizimodu sedentarioak eta ez-aktiboak dituzten pertsonen BBG-an tabako-ohiturak izan ditzakeen eraginak aztertzea eta JF interbentzio ondorengo egokitzapen-ezberdintasunak aztertzea. EXERDIET- HTA ikerkuntzan 222 parte-hartzailek (53,8 ± 7,9 urte) parte hartu zuten. Hamasei asteko ariketa fisiko gainbegiratuarekin interbentzioa egin zitzaien (astean bi egun), bi talde ezberdinetan banatuz erretzaileen taldea (ERT) eta ez-erretzaileen taldea (EERT). Proba guztiak interbentzioaren aurretik eta ondoren errepikatu zitzaien. Interbentzio aurreko taldeen konparaketan, ERT-ak, EERT-rekin konparatuz, gorputzeko masa totalean, gorputz-masa indizean, eta gantz-masan (GM) balioetan altuagoak (p < 0,05) azaldu zituen. Aldiz, BBG-aren aldagaietan (oxigeno-kontsumo pikoan eta baliokide metabolikoan) ez zen ezberdintasunik (p > 0,05) behatu. Interbentzioaren amaieran bi taldeek balio guztietan hobekuntza esanguratsuak azaldu zituzten aurre vs. ondoko balioak aztertuz, bai gorputzeko konposizioan, bai BBG-balioetan. Bestalde, ERT-aren eta EERT-aren hobekuntzen aldaketa-deltari dagokionez, GM eta gantz gabeko masan parametroetan ezberdintasun esanguratsuak behatu ziren ERT-an hobekuntza altuagoak (p < 0,05) behatuz. Hortaz, tabako-ohitura (ERT vs. EERT) kontuan hartu gabe, ariketa fisikoaren interbentzioak BBG-an efektu onuragarriak eragin zituen hipertentsioa, gehiegizko pisua, bizimodu sedentarioak eta ez-aktiboak ziren pertsonetan.

Authors: Castro Franco Ana
Published: December 2022

En la institución del despido colectivo presentan notable incidencia dos factores intrínsecamente relacionados como son la edad y el trabajo. El primer elemento tiene una repercusión directa en la permanencia de la persona trabajadora en la empresa o grupo de empresas afectada por el despido colectivo y en la problemática de la discriminación por razón de la edad, debiendo mostrar una especial atención a los criterios del Tribunal de Justicia de la Unión Europea. El convenio especial de Seguridad Social constituye un medio de aseguramiento del respeto de la prioridad de permanencia a favor de las personas maduras. Esta figura requiere de determinados cambios en su regulación actual, a efectos de ofrecer un tratamiento mucho más coordinado, eficiente y sistematizado.

Granulomatosis with polyangiitis (GPA), previously known as Wegener granulomatosis, is a rare small vessel vasculitis affecting mainly Whites. The prevalence of GPA in the United States is estimated to be 3 of 100,000 individuals. Classically, GPA affects upper airways, lungs, and kidneys, with the upper airways being the most common site. Occasionally, other organs affected by GPA include eyes, skin, joints, and the nervous system. The gastrointestinal system is rarely affected; however, some cases have been reported. In this case report, we present a patient with hemorrhagic gastritis and pancolitis consistent with GPA and discuss features from the literature of gastrointestinal manifestations in patients with GPA.

Splenic myelolipoma is a rare tumor in dogs with an unclear origin. A male 13-year-old Schnauzer dog was presented because of a bump on the left side of the abdomen. Clinical examination and abdominal ultrasound revealed a mass in the spleen. A total splenectomy was carried out, and histopathology revealed a splenic myelolipoma. Before surgery, the patient showed high serum alanine aminotransferase levels, which returned to normal eight months after the resection. Unfortunately, the postoperative follow-up showed increased serum cholesterol and triglyceride levels, suggesting liver compromise. This is the first report of a splenic myelolipoma in Colombia.
Brecha de uso de la atención sanitaria entre la población autóctona e inmigrante en España

Published: December 2022

El objetivo de este trabajo es analizar el grado en que las posibilidades de acceso a los servicios sanitarios de España están limitadas de forma diferencial para la población inmigrante, según su origen, respecto a los autóctonos. Para ello, se han utilizado microdatos del Instituto Nacional de Estadística provenientes de la Encuesta de Condiciones de Vida de 2017, analizando las visitas a médicos de familia, especialistas y dentistas, en los últimos 12 meses, para grupos poblacionales de distinto origen migratorio y controlando por otras características sociodemográficas y de estado de salud. Mediante modelos de regresión logística, la investigación muestra que, aún tras controlar estas variables, la población inmigrante de países no pertenecientes a la UE-28 en España sigue sufriendo una brecha de acceso a algunos de estos servicios sanitarios con respecto al resto de la sociedad española, especialmente determinado por el estatus legal según la nacionalidad que ostenten.
No time to waste: Exploring timeprints of radioactive waste management options in Belgium
Authors: Frenay Sacha , Parotte Céline
Published: December 2022

Following the work of Barbara Adam (1998) and Ulrike Felt (2016), we draw particular attention to ‘timeprints’ in the assessment and selection of radioactive waste management (RWM) options. Using the example of Belgium, we identify four different timeprints mobilized (un)consciously by stakeholders when assessing RWM options, namely trajectorism, promise economy, radioactive waste identity, and multi-situated timeprints. We show that each of these timeprints has a significant impact on the RWM option to be considered and actively determines future radioactive waste management pathways in the form of ‘tacit governance’.

Uluslararası ilişkiler disiplininde hegemonya, güçlü bir devlet ya da devletler grubunun uluslararası sistem üzerinde kurduğu iktisadi, siyasi ve ideolojik üstünlük veya etik-politik liderlik olarak tanımlanabilir. Bu itibarla özellikle II. Dünya Savaşı’ndan sonraki süreçte dünya liderliğine soyunan ABD, SSCB’nin dağılmasından sonra hegemonik güç olarak kabul edilmiştir. Ne var ki 2000’lerden sonra ABD’nin hegemonik gücünü yitirmekte olduğunu, onun yerini ise yeni binyılda Çin’in alacağını ileri süren çalışmalar da disiplin içinde artmaktadır. İşte bu makale, bu tartışmalardan beslenerek Çin’in Latin Amerika ve Karayipler bölgesinde edindiği iktisadi, siyasi, askeri ve ideolojik nüfuzun boyutlarını irdelerken, bulgularını neo-Gramsciyan hegemonya analizi çerçevesinde tartışmaktadır. Bu suretle çalışma, Çin’in Latin Amerika ve Karayipler bölgesindeki gücünün, Amerikan hegemonyasına bölgesel bir tehdit ya da rakip olup olmadığını sorgulamakta, dolayısıyla çok-kutuplu bir siyasal görünüm kazanmaya başlayan uluslararası politikadaki potansiyelleri öngörmeye çalışmaktadır.
ÇEVRE SORUNLARININ KÜRESELLEŞMENİN YAPISAL SORUNLARI AÇISINDAN BİR DEĞERLENDİRMESİ

Published: December 2022

Günümüzde küresel sistemin karşılıklı bağımlılık, kuzey-güney ayrımı, gelir eşitsizliği, kaynak eşitsizliği gibi yapısal sorunları, devletlerarası ekonomik ve siyasi ilişkileri etkileyen önemli unsurlardır. Sanayileşme sürecinde, çevrenin bir kaynak olarak kullanılmasıyla artan üretim, 1970’li yıllarda çevre sorunlarının hızla artmaya başlamasıyla, küresel bir sorun halini almıştır. Günümüzde ise, çevre sorunlarının neden olduğu kuraklık, kaynakların bozulması ya da azalması, çevre kirliliği gibi etkenler, devletlerarası ilişkilerde çatışma riskini arttırmaya başlamıştır. Bu çalışmanın amacı, küresel çevre sorunlarının devletlerin kalkınma hedefleri paralelinde artmasının temel nedeni olarak küreselleşmenin yarattığı eşitsizlikler üzerinden sebep-sonuç ilişkisi kurmaktır. Çalışmanın temel iddiası, çevre sorunlarının kökeninin küreselleşmenin yapısal sorunları olduğu ve bu sürecin gelecekte devletler açısından çatışma riski taşıdığıdır. Çalışmanın ilk bölümünde; küreselleşmenin çevre sorunlarıyla ilişkisi üzerinde durulmuştur. İkinci bölümde ise küreselleşmenin yapısal sorunlarının çevreyle olan ilişkisi, karşılıklı bağımlılık, iktisadi eşitsizlikler, kıt kaynaklar üzerinden ele alınmıştır. Son bölümde ise, çevre sorunlarının neden olduğu riskler, devletlerin temel konulardaki eşitsizlikleri ve çatışma riski üzerinden değerlendirilmiştir.
Historia zjazdów księży katechetów w Królestwie Polskim (1906–1917)
Authors: Ceglarek Roman
Published: December 2022

Przedmiotem artykułu jest problematyka zjazdów katechetycznych prefektów szkolnych w Królestwie Polskim, które odbywały się w Częstochowie i w Warszawie w latach 1906–1917. Całość zagadnienia ujęto w sposób sumaryczny, prezentując je w dwóch aspektach: organizacyjnym (przygotowania i przebieg) i merytorycznym (referaty, dyskusje, postulaty). Dzięki temu przedstawiono nie tylko historię zjazdów katechetycznych w zaborze rosyjskim, lecz także ich dorobek związany z teorią i praktyką katechetyczną tego okresu w tak ważnych obszarach, jak: programy i podręczniki do nauki religii, kwalifikacje i kompetencje zawodowe prefektów szkolnych, duszpasterstwo katechetyczne dzieci i młodzieży oraz tworzenie struktur stowarzyszenia katechetów polskich.
Nowe media po pandemii w świetle nauczania Franciszka
Authors: Szczepaniak Maciej
Published: December 2022

Pandemia koronawirusa ujawniła „znaki czasu”, które Kościół powinien wyjaśniać w świetle Ewangelii. Papież Franciszek nie ma wątpliwości, że staną się one przyczynkiem do poważnych zmian kulturowych: zaprzecza rzeczywistości ten, kto chciałby jedynie udoskonalić istniejące już systemy i reguły. Ujawnienie się naszych złudnych zabezpieczeń, niezdolność do wspólnego działania, rozbicie – mimo że jesteśmy „hiperpołączeni”, powinny więc zaowocować wypracowywaniem nowej kultury komunikacji między ludźmi. Celem artykułu jest refleksja nad miejscem nowych mediów w życiu człowieka po pandemii w świetle nauczania papieża Franciszka. Chociaż media znacząco wpływają na jakość życia i komunikacyjne zdolności osoby ludzkiej, niekiedy sprowadzają człowieka do roli przedmiotu w świecie rzeczy połączonych ze sobą w globalną sieć (IoT, Internet of Things). Zdaniem Franciszka w tym nowym świecie konieczne jest odkrycie fizyczności relacji międzyludzkich na przekór postępującej wirtualizacji, umiejętność wysłuchania innych i spotykania się z ludźmi w realnym świecie, jak również dostrzeżenie Boga Stwórcy jako prawzoru komunikowania się z drugim człowiekiem. Taka postawa pomoże budować – obok Internetof Things – także wspólnotę osób i wykorzystywać narzędzia dla dobra ludzi, stając się siecią osób i siecią dla ludzi.
Network Effect, Business Dynamism and Wage Inequality in a Sharing Economy
Authors: Beladi Hamid , Chao Chi-Chur , Smith Pamela
Published: December 2022

This paper examines the network effect on income distribution and social welfare in a sharing economy with rural-urban migration. A rise in the urban network effect via an increase of the number of users attracts capital to the urban sector. Urban skilled wage rises but rural unskilled wage falls. Due to rising costs from capital rental and skilled wage, urban firms exit if the demand elasticity of urban goods is large. This business-dynamism effect via firm exit mitigates the skilled-unskilled wage gap in the long run. Furthermore, rural-urban migration is mitigated from business dynamism by relocating capital to the rural sector. Network effects thus serves as a mitigator to cope with urban unemployment. In addition, the role of network effects on the effects of changes in the endowments are examined in the sharing economy.
Development of a microfluidic electroosmosis pump on a chip for steady and continuous fluid delivery

Published: December 2022

Infusion therapy is the most common form of therapy used in health care. However, the existing infusion devices show higher flow discrepancies as flow rates decrease to a few nL min−1. As a result, dosing errors can contribute to the morbidity and mortality of patients. In the scope of project 18HLT08 MeDD II – Metrology for drug delivery, this investigation aims at the development of a silicon microchip flow pump capable of steadily and continuously dispense very low flow rates of a few nL min−1. The fabrication methodologies explored here use a combination of typical cleanroom micro/nanofabrication techniques and off-the-shelf equipment. Preliminary tests show flow rates as low as 45 nL min−1 can be obtained in this microfluidic electroosmotic pump. The experimental flow rates are in good agreement with results predicted by multiphysics simulation, with less than 8% deviation ratio. This cost effective electroosmotic micropump has the potential to act as a steady and continuous drug delivery system to neonatal patients as well as to organs on chip (OoC), determining the stability of the shear stress imposed on the cells or the right cell culture medium conditions.
Unexpected dosing errors due to air bubbles in infusion lines with and without air filters

Published: December 2022

The effect of the presence of an air bubble, inside an infusion line, on the time (Tnew) needed for a new medication to reach the patient after a syringe exchange was studied in this paper. If an air bubble escapes through an air filter, then a sudden drop in pressure occurs, causing a relaxation of the compressible part of the syringe, followed by a gradual restoration of the flow rate in the line. We modeled this phenomenon mathematically and measured it experimentally in vitro. In an example with a pump flow rate of 5 mL/h and an air bubble of 1 cm length inside an infusion line (diameter 1 mm) with an air filter, both theory and experiment yield an additional increase of at least 600% in delay time if a naive estimate (based on the size of the bubble alone) is replaced by a more realistic estimate incorporating compressibility. Furthermore, we show that an air bubble in a line without air filter may increase Tnew by a factor 2, depending on the initial position of the air bubble. We conclude that an air bubble in an infusion line causes delays that may not be expected by health care professionals.
Understanding the importance of trust in patients’ coping with uncertainty via health information-seeking behaviors
Authors: Link Elena , Baumann Eva , Klimmt Christoph
Published: December 2022

Disease-related challenges are often associated with perceived uncertainties in individuals, triggering attempts to cope with the situation. Our study aims to understand patients’ coping strategies regarding health information-seeking behaviors (HISBs). It is guided by the Uncertainty Management Theory, and seeks to grant insights into multi-channel HISB by describing how uses of interpersonal and media channels interact to cope with uncertainties, and how trust influences the process of multi-channel HISB. Patients diagnosed with osteoarthrosis (N = 34) participated in qualitative semi-structured interviews, from which five patterns of multi-channel HISB, ranging from a focus on the physician to a focus on the internet, were identified. These patterns are distinguished by underlying functions of trust – including trust serving as an additional coping strategy, and as an important influencing factor for perceiving information as meaningful – and by whether information needs remain and patients turn to multiple sources. These findings form the basis for further theory development considering the iterative nature of HISB and the role of trust.

We also prove some simultaneous sign change results for their eigenvalues.
Empirical Framework for Two-Player Repeated Games with Random States
Authors: Szydłowski Arkadiusz
Published: December 2022

We provide methods for the empirical analysis of a class of two-player repeated games with i.i.d. shocks, allowing for non-Markovian strategies. The number of possible equilibria in these games is large and, usually, theory is silent about which equilibrium will be chosen in practice. Thus, our method remains agnostic about selection among these multiple equilibria, which leads to partial identification of the parameters of the game. We propose a profiled likelihood criterion for building confidence sets for the structural parameters of the game and derive an easily computable upper bound on the critical value. We demonstrate good finite-sample performance of our procedure using a simulation study. We illustrate the usefulness of our method by studying the effect of repealing the Wright Amendment on entry and exit into Dallas airline markets and find that the static game approach overestimates the negative effect of the law on entry into these markets.
