Authors: Chauhan Amarjeet Singh , Nigam Dayal
Published: June 2021

The Smart Bag is a very innovative and helpful project that uses RFID Technology [1] for identifying books / items smartly. The Radio Frequency Identification sensor uses a reader to get information about the item from a tag attached to it. Smart Bag initially used this technology. Technologies or devices which are used in development of The Smart Bag are RFID Sensor, HX711 Load Cell Sensor, NodeMCU, Arduino, and GPS. The Books / items can be identified by using RFID tag and it will store the count of books / items to its memory and matches the items according to schedule. The circuit for communication comprises of NodeMCU and RFID receiver in which passing of messages / alerts, reading of books / item is done. When the books / items are placed inside the bag, the RFID receiver reads the RFID Tag and sends the Books / items in the bag to the NodeMCU [2]. The NodeMCU compares it with the schedule list. If any book / item is missing then the NodeMCU generates an alert of missing books / item. The smart bag has GPS function also, which sends the Real-time Location of a Bag or a Kid to the Guardian or Parents. Initially, this project is for those small kids who regularly go to school.

Published: June 2021

The aim of the study was a comparative assessment of radiation doses to the population of the Voronezh and Irkutsk regions according to the unified state system for monitoring individual doses and radiation-hygienic certification. The objects of research were the territories of the Voronezh and Irkutsk regions, significantly differing in climatic conditions and resources, industrial potential, but comparable in terms of population. The subject of the study was the average territorial values of radiation doses to personnel due to the normal operation of anthropogenic sources, radiation doses to the population due to natural sources and anthropogenic background, radiation doses to patients due to the use of ionizing radiation in medical diagnostics. The method of comparative analysis of effective collective and individual average annual radiation doses was used. In the Voronezh and Irkutsk regions, the priority dose-generating factor is natural radiation, which contribution to the annual effective collective dose is 83.33 and 89.18%, respectively. At the same time, the average individual annual effective doses to the population due to natural sources of ionizing radiation in the Irkutsk region in relation to the Voronezh region are significantly higher for radon – 2,81 times, due to the content of radionuclides in drinking water – 1,93 times and external terrigenous radiation – 1,46 times, which leads to a two-fold difference in the total individual effective doses associated with natural sources of ionizing radiation. These differences are explained by the features of the physical and geographical location of territories. There are significant differences in the values of the average effective annual doses of the population due to global fallouts and past radiation accidents, because a part of the territory of the Voronezh region was exposed to radioactive contamination as a result of the accident at the Chernobyl nuclear power plant (in the Voronezh region – 0.062 mSv / year, in the Irkutsk -0.005 mSv / year). Radiography (63.15 and 67.27%) makes the leading contribution to the value of medical radiation doses, which occupy the second place in the structures of the effective collective annual doses to the population (in the Voronezh region make up 16.46%, in the Irkutsk region – 10.74%) and fluorography (31.29 and 27.41% in the regions, respectively). It was established that the radiation situation in the Voronezh and Irkutsk regions remains stable and safe.

Authors: Pang Dan , Zhang Yizhu , Zhao Changpeng , Xu Xin , Lu Zhiwei , Cai Xinjing
Published: June 2021

Space charge dynamics under sinusoidal voltages are calculated based on bipolar charge transport model. The effects of AC voltage amplitude and frequency on current densities, electroluminescence intensities and space charge densities are investigated. It is shown that the carrier densities increase with the increase of AC voltage amplitude, but the thickness of the space charge layer approximately unchanged. The frequency of AC voltage has no effects on space charge dynamics when the frequency reaches the order of ten.

Authors: Qin Si , Zhou Xiaojun
Published: June 2021

In this paper, a mathematical model for the pneumatic transport of micron silica particles in the dust removal pipeline is established, and the gas-solid two-phase flow in the pipeline is numerically simulated. This paper is mainly based on the FLUENT fluid simulation module in ANSYS WORKBENCH to simulate the motion behavior of particles in the pipeline, and obtained the penetration rate (particle deposition rate in pneumatic conveying) of silica particles in the horizontal straight pipe under different gas flow rates. In the numerical simulation, the influence of particle diameter, shape, lift and other factors on silica particles was considered. Under a large number of simulation conditions, the movement laws of micron silica particles in horizontal pipe pneumatic transport were obtained, and the influence of the above factors on the movement laws of the particles were determined.

Published: June 2021

The article considers the possibilities of developing the combined discrete-continuous vibratory systems, in which the disturbing member is designed in the form of the uniform elastic rod with distributed inertia and stiffness parameters. The forced oscillations of the continuous member of the three-mass vibratory system are analyzed. Based on the Krylov-Duncan functions (circular and hyperbolic functions), the system of equations describing the motion of the continuous rod is derived. The novelty of the present paper consists in deriving the mathematical model of the discrete-continuous vibratory system, in which the model of the discrete subsystem is combined with the model of the continuous subsystem by applying the reactions in the supports holding the uniform elastic rods. The inertia-stiffness parameters of the vibratory system are determined and the analytical dependencies for calculating the reactions in supports are derived. The frequency-response curves of the considered discrete-continuous vibratory system are constructed. The deflection (bending) diagram of the continuous members is plotted for the case of forced oscillations of the combined discrete-continuous vibratory system.

Published: June 2021

Magnetic memory testing is a new nondestructive testing technology, which can detect the early damage of ferromagnetic components such as stress concentration. In this paper, the coupling model between the stress of ferromagnetic material and its magnetic leakage field is established. In this model, the relative change rate of permeability of ferromagnetic material is proportional to the stress, the change of permeability and the saturation magnetic induction. The experimental results show that the model can well describe the relationship between stress and leakage magnetic field.

Authors: Simental-Mendía Luis E. , Simental-Mendía Mario , Sánchez-García Adriana , Linden-Torres Enrique
Published: June 2021

Background:

It has been suggested that hydroxychloroquine may have positive effects on LDL-C,
HDL-C, and triglyceride levels; however, the hypolipidemic activities of this drug are still uncertain.

Objective:

The aim of this meta-analysis of randomized controlled trials was to explore the effect of hydroxychloroquine
on circulating lipid concentrations.

Methods:

Randomized controlled trials examining the impact of hydroxychloroquine on lipid parameters were
searched in PubMed, Web of Science, Scopus, and Google Scholar databases. Meta-analysis was performed using
a random-effects model and sensitivity analysis through the leave one-out method.

Results:

Meta-analysis showed that patients receiving hydroxychloroquine therapy significantly decreased total
cholesterol (WMD: 0.18 mmol/L, 95% CI: -0.28, -0.08, I2 = 6%, p = 0.0004), LDL-C (WMD: -0.21 mmol/L,
95% CI: -0.36, -0.06, I2 = 75%, p = 0.006), triglycerides (WMD: -0.09 mmol/L, 95% CI: -0.15, -0.04, I2 = 22%,
p = 0.001), and non-HDL-C (WMD: -0.28 mmol/L, 95% CI: -0.45, -0.12, I2 = 0%, p = 0.0009), and increased
HDL-C concentrations (WMD: 0.03 mmol/L, 95% CI: 0.00, 0.06, I2 = 0%, p = 0.03).

Conclusion:

Our results suggest that hydroxychloroquine improves lipid parameters by reducing total cholesterol,

Assessment of Once Daily Controlled-release Ibuprofen Matrix Tablets
Prepared using Eudragit ®E100/Carbopol® 971P NF Polymers and their
Salt Combinations
Authors: Obeidat Wasfy M. , Al-Natour Mohammad Ahmad
Published: June 2021

Introduction:

Hydrophilic polymers that swell or dissolve in aqueous media can have
the potential to prepare controlled/sustained dosage forms for weakly acidic and poorly soluble
drugs.

Objective:

The main objective of this study is to utilize Eudragit®E100 (EE) and Carbopol®971P
NF (Cp) polymers and their salt forms for the preparation of a once-daily controlled-release matrix
tablet for model drug, Ibuprofen (IB).

Methods:

Combinations of the polymers in their base forms (EE)/(Cp) or in their salt forms (EEHCl/
CpNa) were compressed with (IB) into single layer matrix tablets, or otherwise into bilayer
tablets. Dissolution profiles were constructed using three different consecutive stages (pH 1.2, 4.8
and 6.8).

Result:

It was found that the incorporation of (EEHCl) modified the release rates of (IB) from
(Cp) based matrix tablets. However, a major enhancement of (IB) release rates occurred when the
polymers were combined in their salt forms in a 1:1 ratio by weight. In addition, a bilayer tablet
was prepared wherein a relatively rapidly disintegrating layer composed of polymers salts (EEHCl
and CpNa), and a second layer containing only (Cp) polymer in its base form in a 1:2 weight ratio
possessed excellent release properties and mechanical strength.

Conclusion:

It was concluded that the prepared bilayer tablet could be promising for controlling
the release rates of (IB) in an extended manner to allow once-daily administration with an improved
pH-independent release behavior.

Mechanism of Actions of Dexamethasone Against COVID-19 Predicted by Alpha Shape Analysis of Binding Sites
Authors: Zhu Mengxu , Ghosh Avirup , Yan Hong
Published: June 2021

Background:

COVID-19 emerged in late 2019 and became a pandemic disease with severe
mortality and morbidity. No specific remedy exists at present, but some drugs, such as Dexamethasone,
have shown clinical benefits against the causative agent, the SARS-CoV-2 virus.

Objective:

To analyze the binding affinity between drugs and an SARS-CoV-2 protein through geometrical
methods and to study the theoretical effectiveness of Dexamethasone as a potential treatment
for COVID-19.

Method:

The binding affinity of Dexamethasone to the target SARS-CoV-2 protein was compared
with those of different inhibitors. Drug molecules were docked to the SARS-CoV-2 main protease,
and the system was simulated by molecular dynamics, allowing alpha shape analysis to extract geometrical
features, such as the matching rates of atoms, solid angles, and the distances between atoms
at interfaces. Binding affinities between drugs and the main protease were assessed by these
geometrical data and the free energy of binding.

Results:

The behaviour of Dexamethasone was similar to other inhibitors. The efficacy of Dexamethasone
as a treatment may be due to it being a glucocorticoid and its properties as a potent inhibitor.

Conclusion:

This study revealed the mechanism of action of Dexamethasone and provided a geometrical
method to distinguish among potential drugs for the treatment of COVID-19.

Published: June 2021

Background:

Ischemic stroke is a serious public health problem. Despite extensive researches
focusing on the area, little is known about novel treatments.

Objective:

In this study, we aimed to investigate the effects of Capparis spinosa (C. spinosa) extract
in the middle cerebral artery occlusion (MCAO) model of ischemic stroke.

Methods:

Wistar rats underwent 30-min MCAO-induced brain ischemia followed by 24 h of
reperfusion. C. spinose was administrated orally once a day for 7 days before the induction of
MCAO. The neurologic outcome, infarct volume (TTC staining), histological examination, and
markers of oxidative stress, including total thiol content, and malondialdehyde (MDA) levels,
were measured 24hr. after the termination of MCAO.

Results:

Pretreatment with C. spinosa reduced neurological deficit score, histopathological alterations,
and infarct volume in treated groups compared to the stroke group. Furthermore, pretreatment
with C. spinosa extract significantly reduced the level of MDA with concomitant increases
in the levels of thiol in the brain tissues compared to the stroke group.

Conclusion:

Our study demonstrates that C. spinosa extract effectively protects MCAO injury
through the attenuation or the suppression of the oxidative stress.

Immunostimulatory agents such as adjuvants, cytokines, and antibodies have
a great potential for the treatment of disease conditions. However, their direct
administration may lead to suboptimal pharmacokinetics, compromised targeting and
vulnerability to biodegradation. To overcome these drawbacks, nanoparticles play a
vital role and they improve the delivery mechanism of these therapeutic agents. The
nanoparticle in conjugation elevates the bioavailability of the encapsulated payloads. In
this study, we intended to discuss these immunostimulants when delivered by
nanoparticles.

Authors: Jappens Maaike , Van Bavel Jan
Published: June 2021

Grootouders spelen vaak een belangrijke rol in het leven van hun kleinkinderen. Na echtscheiding komen echter heel wat familierelaties mogelijk onder druk te staan. Dit artikel onderzoekt het verband tussen echtscheiding van ouders en contacten tussen kleinkinderen en grootouders. We baseren ons hiervoor op de antwoorden van meer dan 1000 kinderen tussen 10 en 25 jaar en hun moeder of vader in de survey ‘Scheiding in Vlaanderen’.  Resultaten tonen dat, in vergelijking met kinderen waarvan de ouders nog gehuwd zijn, kinderen met gescheiden ouders hun grootouders, vooral die van vaderskant, minder frequent zien. Sommigen verliezen zelfs alle contact.  De verblijfsregeling van kinderen blijkt een belangrijke rol te spelen: naarmate kinderen een groter of kleiner gedeelte van de tijd bij vader respectievelijk moeder wonen, zien zij ook de grootouders langs die kant meer of minder.
Abstract :
Grandparents play an important role in the lives of children, also when the parents of the grandchildren divorce. Rising divorce rates however raise concerns about the impact on family ties. Based on data from more than 1000 children between 10 and 25 years old and their parents participating in the survey “Divorce in Flanders”, this article investigates the association between a parental divorce and contacts between children and their grandparents. Results show that, compared to children whose parents are still married, children of divorced parents have less frequent contact with their grandparents, and especially paternal grandparents. In some cases all contact gets lost. The living arrangement of grandchildren seems to be decisive in this matter.
De impact van opvoedingsstress en depressieve symptomen op de ouder‐kind communicatie van gehuwde moeders en vaders
Authors: Ponnet Koen , Pasteels Inge , Bastaits Kim , Vanderheyden Griet , Mortelmans Dimitri
Published: June 2021

In deze bijdrage gaan we na in welke mate opvoedingsstress en depressieve symptomen van gehuwde moeders en vaders een invloed hebben op de eigen communicatie met het kind (actoreffecten) en op de communicatie van de andere ouder met het kind (partnereffecten). Gegevens uit het project “Scheiding in Vlaanderen” van 196 niet‐gescheiden gezinnen werden geanalyseerd, waarbij gehuwde moeders en vaders hun eigen opvoedingsstress en depressieve symptomen beoordeelden, en waarbij de ouder‐kind communicatie door zowel het kind als de ouders beoordeeld werd.  Structurele vergelijkingsmodellen tonen aan dat zelfgerapporteerde opvoedingsstress de eigen ouder‐kind communicatie beïnvloedt (actoreffect), terwijl zelfgerapporteerde depressieve symptomen een impact hebben op de ouder‐kind communicatie van de andere ouder (partnereffect). Deze effecten zijn even sterk voor moeders en vaders: de samenhang tussen opvoedingsstress en depressieve symptomen enerzijds en ouder‐kind communicatie anderzijds is dus genderneutraal.  De resultaten hebben implicaties voor toekomstig onderzoek maar ook voor deskundigen. In toekomstige studies over ouder‐kind relaties moeten bij voorkeur zowel vaders als moeders betrokken worden. Ook opvoedingsondersteunende diensten moeten beide ouders in hun vizier nemen ongeacht of de hulpvraag van een van beide ouders komt. Partnereffecten geven immers aan dat zelfs milde vormen van depressieve symptomen van de ene ouder een impact kunnen hebben op de ouder‐kind communicatie van de andere ouder.
Abstract :
This study examines how parenting stress and depressive symptoms experienced by mothers and fathers influence their own (actor effects) and the partner’s (partner effects) parent‐child communication. Based on the Actor‐Partner Interdependence Model, data from 196 families were analyzed, with both parents rating their parenting stress and depressive feelings, and parents as well as children rating the open parent‐child communication.Actor effects were found between parenting stress and open parent‐child communication, while partner effects were prominent between depressive symptoms and open parent‐child communication. The results provide no evidence for gender differences in the strength of the pathways to open parent‐child communication. Implications for future research and practitioners are provided.

Authors: Bastaits Kim , Mortelmans Dimitri , Van Peer Christine
Published: June 2021

Uit voorgaand onderzoek blijkt dat een effectieve opvoeding een positieve invloed heeft op het welbevinden van kinderen, ook na een ouderlijke echtscheiding. In deze studie gaan we ten eerste na of dit verband ook geldt voor kinderen van gescheiden ouders in Vlaanderen. Ten tweede onderzoeken we of zowel het geslacht van de ouder als de verblijfsregeling een verschil maken voor de associatie tussen ouderlijke opvoeding en welbevinden van kinderen na echtscheiding. We analyseren hiervoor een subsample van de dataset “Scheiding in Vlaanderen – SiV”, met informatie over 363 kinderen en hun gescheiden ouders. Uit de resultaten blijkt vooreerst dat voornamelijk ouderlijke steun positief gerelateerd is aan de zelfwaardering en levenstevredenheid van kinderen na een ouderlijke echtscheiding. Daarnaast vinden we ook dat de opvoeding door de vader even belangrijk is voor de zelfwaardering en levenstevredenheid van het kind als de opvoeding door de moeder, zowel voor kinderen in co-ouderschap als voor kinderen met een residentiële moeder en een niet‐residentiële vader.
Abstract :
From previous research, it has become clear that effective parenting has a positive impact on children’s well‐being, even after a parental divorce. In this study, we first investigate whether this association can also be found for children of divorced parents in Flanders. Secondly, we examine whether gender of the divorced parent and custodial arrangements could result in some heterogeneity regarding this association. Therefore, we analyze a subsample of the “Divorce in Flanders – DiF” dataset, which provides information on 363 children and their divorced parents. Results reveal that parental support has a positive impact on children’s self‐esteem and satisfaction with life. Furthermore, the parenting of the father appears to be as important for children’s self‐esteem and satisfaction with life as the parenting of the mother. This holds for children in joint custody as well as for children with a residential mother and a non‐residential father.

Het is geweten dat het hebben van een partner en kinderen een effect heeft op iemands sociale leven. Maargeldt dat ook voor gescheiden ouders? Zij hebben immers een ex‐partner en eventueel een nieuwe partner, en zehebben ook een specifieke verblijfsregeling die in acht genomen kan worden. De focus ligt in dit artikel op degedeelde verblijfsregeling die recent door de Belgische wetgever naar voren werd geschoven. Data van hetScheiding in Vlaanderen‐onderzoek wordt gebruikt, waarin 1.506 gescheiden ouders werden geïnterviewd in2009 en 2010. De resultaten tonen aan dat vooral gescheiden ouders binnen een gedeelde verblijfsregeling hunsociaal leven op peil houden en sociaal geïntegreerd blijven. Deze gescheiden co‐ouders participeren meer insociale activiteiten en onderhouden beter hun sociale contacten.
Abstract :

It isimportant to consider custody arrangements in this case. The research question is how custody ar‐rangements affect divorced parents’ possibilities to participate in social activities and to maintaintheir social contacts. Focus is placed on the recent post‐divorce parenting model of joint physicalcustody, taking Belgium as a pioneer case study. Data from the Divorce in Flanders survey of 2009‐2010 are used (N = 1,506 divorced parents). Results show that joint physical custody helps divorcedparents to stay socially integrated. They engage in more social activities and maintain their socialnetworks.

Published: June 2021

In dit artikel wordt gekeken naar de mate waarin partners een invloed hebben op het vrouwelijke arbeidsaanbod.  Vanuit de economische principes van specialisatie en economische behoefte verwachten we dat het arbeidsaanbod van vrouwen negatief beïnvloed wordt door de arbeidstroeven van hun partner. Deze verwachtingen worden in het huidige artikel in een echtscheidingscontext geplaatst. We bekijken de samenhang tussen de arbeidstroeven van de mannelijke partner en het vrouwelijke arbeidsaanbod, en maken hierbij een onderscheid naar ooit‐ en nooit‐gescheiden vrouwen. Er wordt immers verwacht dat het meemaken van een scheiding zorgt voor een onafhankelijkheidseffect, waarbij de arbeidstroeven van de partner minder van belang zullen zijn in het arbeidsbeslissingsproces. Met de data van Scheiding in Vlaanderen (SiV) kunnen we enkel associaties tussen beide partners vaststellen. Deze associaties kunnen mogelijk ook voortspruiten uit een verschillend partnerselectieproces voor ooit‐ en nooit‐gescheidenen. We vinden dat vrouwen met een partner met een hoger inkomen minder vaak werken. Dit geldt zowel voor ooit‐ als nooit‐gescheiden vrouwen. Vrouwen waarvan de partner een hoger opleidingsniveau of een hoger arbeidsaanbod heeft, blijken zelf ook vaker te werken indien het gaat om een eerste huwelijk (nooit‐gescheiden), maar minder vaak indien het gaat om een nieuwe relatie (ooit‐gescheiden). Partners in nieuwsamengestelde gezinnen zijn dus heterogener op vlak van hun arbeidsaanbod en ‐troeven.
Abstract :
This article is about the influence of partners on women’s labour supply. Based on economic principles, we expect women’s labour supply to be negatively influenced by their partner’s labour market resources. In the current article, this association is analysed in a divorce context. We expect the labour supply of never‐divorced women to be more negatively affected by the labour market resources of their partners than the labour supply of repartnered women who experienced a divorce. Put differently, we expect the labour supply of ever‐divorced women to be less dependent upon their partner’s labour market resources. We determine some associations with data from Divorce in Flanders (DiF). Next to differences in partner effects, these associations can also be attributed to differences in the partner selection process between never‐divorced and ever‐divorced women. We find that women with a high‐income partner tend to work less often, regardless of having experienced a divorce. If their partner works more or has a higher educational level, never‐divorced women tend to work more often themselves. Ever‐divorced women, on the other hand, tend to work less often if their new partner works more or is higher educated.

Sinds 2001 is professionele echtscheidingsbemiddeling wettelijk erkend als mogelijk onderdeel van een echtscheidingsprocedure. Op basis van gegevens van het project “Scheiding in Vlaanderen” gaan we na wie op de hoogte is van de mogelijkheid tot bemiddeling en wie er vervolgens ook gebruik van maakt. Hierbij hebben we aandacht voor de wetswijziging van 18 juli 2006 die de rechter verplicht ouders die gaan scheiden te informeren over professionele echtscheidingsbemiddeling. Uit de resultaten blijkt dat hoogopgeleiden vaker professionele echtscheidingsbemiddeling kennen. Professionele echtscheidingsbemiddeling vervolgens ook gebruiken komt meer dan gemiddeld voor wanneer de vrouw van het ex‐koppel hoger opgeleid is. Bovendien is de doelgroep die in het vizier was door de wet van 2006 bereikt. Ouders zijn na de wetswijziging meer op de hoogte van professionele echtscheidingsbemiddeling dan andere (ex‐)koppels. Gezien er een duidelijk effect te merken is van de informatieverstrekking door rechters op het kennen van bemiddeling lijkt het aangewezen de informatieplicht te veralgemenen. Meer nog echter lijkt het aangewezen professionele echtscheidingsbemiddeling te integreren in een ruimer aanbod van echtscheidingszorg waarin alle relevante organisaties krachten bundelen om geïnformeerde keuzes en kwaliteitsvolle echtscheidingstrajecten na te streven.
Abstract : 
Since 2001, professional divorce mediation is legally recognized as a possible part of a divorce procedure. Based on data from the study "Divorce in Flanders" we examine who is aware of the possibility of mediation and who is using it. We highlight the amendment of 18 July 2006 that obligates the judge to inform parents who are divorcing about the possibility of professional divorce mediation. The results show us that higher educated persons have more knowledge about professional divorce mediation. The use of professional divorce mediation subsequently comes more than average when the wife of the ex‐couple is higher educated. Moreover, the target group of the amendment of 18 July 2006 is reached. After the amendment, parents are better informed about the possibility of divorce mediation than other divorcing couples. Given a clear effect of the provision of information by judges on the knowledge and also on the use of mediation for this target group, it seems appropriate to generalize the obligation to inform about this specific procedure. Furthermore it’s important to integrate professional divorce mediation as one alternative in a wide range of relevant organizations so individuals can reach an informed decision as well as a high quality divorce trajectory.
Sporen van ouderverstoting in het SiV‐onderzoek

Inzicht in ouders en kinderen die geen contact meer hebben na scheiding blijft onderbelicht in het huidige familieonderzoek. Een erg specifieke vorm van een gebrek aan contact is ouderverstoting. Hoewel enkele studies dit thema al belicht hebben, blijft dit onderzoek schaars en kent het methodologisch beperkingen. Met deze studie willen we dan ook bijdragen aan onderzoek naar ouderverstoting en vertrekken we vanuit de grootschalige multi‐actorstudie ‘Scheiding in Vlaanderen – SiV’. Twee onderzoeksvragen worden beantwoord: (1) “Wat is de prevalentie van het vermoeden van ouderverstoting na scheiding in Vlaanderen?” en (2) “Hangt het vermoeden van ouderverstoting samen met een specifiek scheidingsproces?”.Daartoe analyseren we gegevens van zowel ouders (n = 1172) als kinderen (n = 499). Als eerste worden bivariate analyses uitgevoerd om de prevalentie van een vermoeden van ouderverstoting na te gaan bij zowel ouders als kinderen. Daarna wordt een multiple correspondentie‐analyse gebruikt om inzicht te verwerven in de eventuele samenhang van een vermoeden van ouderverstoting met het scheidingsproces. Hoewel een vermoeden van ouderverstoting niet vaak voorkomt, rapporteren zowel ouders als kinderen dat dit vaker voorkomt bij vaders dan bij moeders. Kinderen rapporteren wel hogere percentages dan ouders. Daarnaast blijkt ook dat een vermoeden van ouderverstoting vaker voorkomt bij een problematisch scheidingsproces.
Abstract :
Previous research on parent‐child relationships after divorce mainly concentrated on parents and children who still have contact. Nevertheless, few studies have focused on the non‐contact between parents (mostly fathers) and children after divorce. A very specific form of non‐contact is parental alienation, on which research is very scarce and limited to small samples. So, with this study, we will investigate parental alienation after divorce for a large, multi‐actor sample from the “Divorce in Flanders”‐project. Two research questions will be answered: (1) “What is the prevalence of parental alienation towards mothers as well as towards fathers after divorce?” & (2) “How are characteristics of the divorce process related to parental alienation?”.  We integrate two perspectives in this paper by analyzing a parent‐dataset (n = 1172) as well as a child‐dataset (n= 499). First, we establish the prevalence of parental alienation with bivariate analyses. Second, multiple correspondence analyses are used to gain insight in the association between the divorce process and parental alienation. Results indicate that parental alienation affects a small group of families and father alienation is more common than mother alienation. Moreover child reports are higher than parent reports. Regarding the association between parental alienation and the divorce process, it is found that parental alienation is more common amongst problematic divorce processes.
Низкотемпературная аномалия диэлектрических свойств наночастиц магнетита

This paper is devoted to study the dielectric response of magnetic alkali borosilicate glasses containing single-domain magnetite nanoparticles in the temperature range 5 - 100 K on heating and on cooling in magnetic fields from 0 to 14 T in the frequency range from 1 Hz to 160 kHz. It is shown, that an anomaly in the dielectric response is observed in the temperature range 15 - 50 K for single-domain magnetite nanoparticles. The position of this peculiarity is in good agreement with the transition to the relaxor state observed in the bulk material. The temperature hysteresis of this anomaly has been observed on heating and cooling, and it decreases with decreasing measurement frequency.
Developing an Educational Website for Women With Endometriosis-Associated Dyspareunia: Usability and Stigma Analysis (Preprint)

BACKGROUND

Endometriosis is a chronic condition that affects approximately 10% of women worldwide. Despite its wide prevalence, knowledge of endometriosis symptoms, such as pelvic pain, and treatments remains relatively low. This not only leads to a trivialization of symptoms and delayed diagnosis but also fuels myths and misconceptions about pain symptoms. At the same time, the use of web-based platforms for information seeking is particularly common among people with conditions that are perceived as stigmatizing and difficult to discuss. The Sex, Pain, and Endometriosis website is an educational resource designed to provide evidence-based information on endometriosis and sexual pain to help people understand the condition, feel empowered, dispel myths, and destigmatize endometriosis-associated sexual pain.

OBJECTIVE

The study objective is to evaluate the usability of the website and assess for destigmatizing properties of sexual health–related web-based resources.

METHODS

We conducted a usability analysis by using a think-aloud observation, a postsystem usability questionnaire, and follow-up interviews with 12 women with endometriosis. The think-aloud data were analyzed using the framework by Kushniruk and Patel for analyzing usability video data, the questionnaire data were analyzed using descriptive statistics, and the follow-up interviews were analyzed using simple content analysis. We conducted a usability assessment by deductively analyzing the interview data via a trauma-informed care framework and a content analysis approach.

RESULTS

Through usability analysis, we found the website to be simple, uncluttered, satisfying, and easy to use. However, 30 minor usability problems related to navigation; website response; the comprehension of graphics, icons, and tabs; the understanding of content; and mismatch between the website and users’ expectations were reported. In our stigma analysis, we found the web content to be nonstigmatizing. The participants suggested ways in which websites could be designed to address stigma, including ensuring privacy, anonymity, inclusiveness, and factual and nonjudgmental content, as well as providing opportunities for web-based engagement.

CONCLUSIONS

Overall, the participants found the website to be useful, easy to use, and satisfying. The usability problems identified were largely minor and informed the website redesign process. In the context of the limited literature on stigma and website design, this paper offers useful strategies on how sexual health–related websites can be designed to be acceptable and less stigmatizing to individuals with sensitive health issues.
