Published: May 2023

The digital era affects students' attitudes toward utilizing applications as learning media. This phenomenon can be used to boost student achievement, but it can also have negative consequences, such as chatting while studying or cheating on school exams. To support the positive and reduce the negative impact of smartphone use, it is necessary to supervise this activity. The supervision can be done by utilizing a camera to detect a smartphone. The YOLOv5 algorithm was used, which is known for its good speed and accuracy in object detection. This smartphone detection system can be controlled, so the application is adjustable to the needs of learning activities. Collecting a dataset, annotating, training objects, writing program code, and testing the system are all stages in the development of this system. The dataset used in this research consists of 1,038 smartphone images from the internet and camera-captured images. This detection system was built to assist teachers in monitoring the use of smartphones by students. The results of this model training are 77.7% mean average precision, 93.2% precision rate, and 71.7% recall rate under varying lighting conditions.
Стратегии преодоления стресса населением Вологодской области: опыт социологического исследования
Authors: Смолева Елена Олеговна
Published: May 2023

В статье обсуждаются стратегии преодоления стресса населением конкретного региона, которые классифицируются по направленности, эффективности и сферам копинга. Информационную базу исследования составили данные социологического опроса населения Вологодской области (объем выборки 1500 респондентов; метод анкетирования). В качестве основных групп поведенческих реакций на стресс рассмотрены стратегии преодоления, избегания и обращения за социальной поддержкой. Автор обосновывает выбор для проведения опроса населения методики Д. Амирхана «Индикатор копинг-стратегий преодоления стресса» в адаптации В.М. Ялтонского. В ходе исследования предпринята попытка актуализации методики для опросов общественного мнения в регионе. На основании данных по частоте попадания в стрессовые ситуации различных групп населения в 2018 и 2021 гг. сделан вывод, что стрессогенность социальной ситуации усилилась. С помощью структурно-факторного анализа на эмпирических данных построена четырехфакторная модель копинг-стратегий, выдвинуты предложения по улучшению методики.
Превалирующая стратегия борьбы со стрессом у населения Вологодской области — разрешение проблем; на втором месте находится стратегия поиска социальной поддержки. Реже жители региона указывают на применение стратегии избегания проблем. Выявлены различия в применении копинг-стратегий различными социально-демографическими группами, при этом они наиболее выражены в разрезе доходных групп. С помощью кластерного анализа среди населения области были выделены три различающиеся по использованию копинг-стратегий группы. Показано, что в ситуации стресса действия, относящиеся к стратегии избегания проблем, реализуют около трети респондентов.

«Обмыть» и «проставиться»: советские ритуалы редистрибуции благ
Authors: Кирзюк Анна Андреевна , Архипова Александра Сергеевна
Published: May 2023

Статья посвящена неформальным ритуалам, которые в разговорном русском языке обозначаются словами «обмыть» и «проставиться» и заключаются в угощении группы по случаю приобретения индивидом материального или символического блага. Эти ритуалы рассматриваются как частный случай символической редистрибуции: «проставляясь» по случаю приобретения блага, индивид возвращает его часть коллективу. В условиях «ограниченного блага» (Дж. Фостер) такие ритуалы особенно актуальны, поскольку позволяют благополучателю защититься от возможной зависти окружающих. Советская экономическая система удерживала образ «ограниченного блага» в когнитивных ориентациях людей и в то же время развивала у них умение и привычку поддерживать личные отношения через акты немонетарного обмена. Поэтому участие в таких ритуалах было не вполне добровольным: у многих советских людей существовали представления о моральных и сверхъестественных санкциях за отказ «обмывать» и «проставляться», а индивид нередко сталкивался с давлением коллектива, требующим от него поделиться полученным благом. После распада советской системы эти ритуалы не исчезли совсем, но стали менее распространенными и потеряли принудительный характер. Исследование основано на интервью с бывшими советскими людьми и архивных материалах, а также на автоэтнографических эссе и анкетах студентов, родившихся после распада СССР.
Благодарность. Исследование выполнено при поддержке гранта Российского научного общества № 20-18-00342 «Институциональные и неинституциональные ритуалы в структуре позднесоветского общества (1956—1985)».

Факторы, устойчивость и реализация репродуктивных намерений в России
Authors: Макаренцева Алла Олеговна , Бирюкова Светлана Сергеевна
Published: May 2023

Статья продолжает и обобщает накопленный авторами опыт исследований репродуктивных намерений в России, включая оценку их динамики и степени реализации с первой половины 2000-х годов до настоящего времени. Авторы опираются на кросс-секционные и панельные данные двух репрезентативных выборочных обследований населения: опроса «Родители и дети, мужчины и женщины в семье и обществе», проведенного в 2004, 2007 и 2011 гг., и опроса «Человек, семья, общество» 2017 и 2020 гг. Если в 2004—2011 гг. принципиальных изменений в распределении ответов о репродуктивных намерениях не наблюдалось, то к 2017 г. респонденты стали значительно чаще выражать «определенно положительные» репродуктивные намерения. При этом уровень реализации определенных намерений среди женщин не изменился за весь период наблюдения и устойчиво составляет около 40%. Наиболее значимым фактором реализации положительных репродуктивных намерений на протяжении всего периода наблюдения оказался партнерский статус, причем шансы появления ребенка повышаются как в связи с наличием стабильного партнерства, так и в связи со сменой партнера. К значимым факторам, отрицательно связанным с реализацией репродуктивных намерений, относится низкая субъективная оценка материального положения семьи.

Various methods of nondestructive testing, including active infrared thermography, are used to detect latent subsurface defects in the contact of layers in multilayer products. One of the main difficulties using this method consists in processing and interpreting the thermal image data. The peculiarity of investigated defects of bimetal plate layers continuity violation is that the depth of defect location is known and the main task is to determine its size. Some methods are used for this purpose including analysis of spatial temperature profiles. Aim. To analyse the use of various approaches to determining the transverse dimensions of a delamination between metals in simulating active thermal non-destructive testing of steel-aluminium plates. Materials and methods. Mathematical and computer simulating methods, numerical differentiation are used. The delamination size is determined by projections of half the height of the amplitude signal and the extremum of the derivative of the temperature signal function. Calculations and graphical constructions are performed using the mathematical package GNU Octave. Results. Numerical simulation is carried out for different values of heat flow power, heating and cooling time. The temperature signal distribution over the surface of a multilayer bimetallic plate has been plotted. The values of the defect radius according to the projections of the characteristic points are determined. Conclusion. The results of simulation allow us to conclude that using the projection of the extremum of the temperature signal derivative function allows us to accurately estimate the defect size, while in the case of the point projection cor¬responding to half of the signal amplitude height, the result is underestimated. The obtained results can be used for further experimental studies of processes of active thermal non-destructive testing of products made of multilayer bimetallic materials.
Quenching with Aqueous Polymer Solutions
Authors: Lübben T. , Frerichs F.
Published: May 2023

Quenching with aqueous polymer solutions has some distinct advantages over classical oil quenching. Among these are the good environmental properties and the possibility to adjust the quenching performance between oil and water quenching. Nevertheless, critical aspects must also be taken into account. When quenching steel parts with polymer solutions, “explosion-like” phenomena can occur, often accompanied by large cooling rate changes. These “explosions” can lead to pressure waves and vibrations in the quenching tank, which in the long run can even destroy weld seams of the quenching tank. In the framework of a research project, experimental investigations were carried out in a laboratory quenching bath and in an industrial quenching tank. The polymer type, the type of incident flow, the flow velocity, the bath temperature and the size of the test shafts were varied. Near-surface temperature measurements inside the shafts were performed to characterize the resulting quenching processes. Simultaneously, electrical conductivity measurements and audio and video recordings were made to localize insulating films on the surface and their collapse. To systematize and characterize the large number of measurement results, characteristic types of cooling processes and characteristic numbers for their characterization were defined and will be presented in this paper.
Los comienzos del género policial en Latinoamérica: el período vanguardista-modernista
Authors: Setton Román
Published: May 2023

El artículo revisa la historia del género policial en Latinoamérica y, sobre todo, la ya consagrada e indiscutida fijación de sus comienzos en la década de 1940. Se intenta mostrar de qué modo se construyó esa historia de los orígenes que, por un lado, niega una cantidad de textos previos importantes pertenecientes al género policial y, por otro, conforma una historia adecentada del género que lo “ennoblece” al vincular su origen con la “alta literatura” y una suerte de “aristocracia cultural” y niega, a su vez, los vínculos del género policial con la cultura y la literatura populares. A su vez, el texto caracteriza aquello que denominamos el período vanguardista-modernistas del género, que puede situarse, a grandes rasgos, desde 1920 hasta entrada la década de 1940.

Criticising Capitalism in the City and on the Stage: The City Street Movement Occupy Wall Street and Tim Price’s Protest Song
Authors: Schwanecke Christine
Published: May 2023

Following the 2022 CDE conference’s concern regarding “how theatre and the city are productively embroiled and [. . .] how contemporary Anglophone theatre has redefined [. . .] [and blurred the] borders between centre and periphery, street and stage, performer and spectator” (Garson et al.), I will focus on Tim Price’s Protest Song, which was commissioned by the National Theatre and was staged there in December 2013. Setting the play in the streets of London in front of the iconic urban space of St Paul’s Cathedral, starring a homeless main character, and transgressing the boundaries between theatrical and actual spaces, Price arguably questions conventional urban and social binaries as well as economic and social hierarchies. With the help of experimental and critical strategies, he examines the city street movement Occupy Wall Street and its repercussions. The present article analyses these strategies and asks how they represent, perform, question, and assess urban hierarchies, city street activism, and the financial sector, as they are symbolised by the (urban and mental) spaces of London as capital and London as city of capital. I will furthermore look into how Price’s strategies reframe social inequality and turbo-capitalism as well as to what extent they redefine the borders between centre and periphery, street and stage, performer and spectator.
Radonification of a cylindrical Lévy process
Authors: Alvarado-Solano Anddy E.
Published: May 2023

In this work, we present a direct proof about radonification of a cylindrical Lévy process.
The radonification technique has been very useful to define a genuine stochastic process starting from a cylindrical process; this is possible thanks to the Hilbert–Schmidt operators.
With this work, we want to propose a self-contained simple proof to those who are not familiar with this method and also present our result which is to apply the radonification method to the case of a cylindrical Lévy process.
Effects of microstructure characteristics on the transverse moisture diffusivity of unidirectional composite
Authors: Wang Meng , Hang Xiaochen
Published: May 2023

To reveal the effects of the microstructure characteristics including fiber shape, void, fiber distribution pattern, and interphase on the transverse moisture diffusivities of unidirectional composites, the steady analysis method based on Fick’s law is adopted. The predicted numerical results are compared with the results from the analytical models to demonstrate the accuracy. From the simulation results, it is found that the increase in the oscillation amplification of non-circular fibers contributes to the orthotropy of diffusivity properties, which attributes to different barrier effects along different directions. The consideration of interphase relieves the barrier effects and the predicted diffusivity values are increased significantly. The effects of voids increase with the void volume fraction and are dependent on the voids’ location. If the fiber random distribution pattern is considered, it is found that the average values of predicted diffusivity decrease gradually with the increase in the number of oscillations.
Effect of free boundary on the performance of single expansion nozzle
Authors: Inturi Dakshina Murthy , Pinnam Lovaraju , Vegesna Ramachandra Raju
Published: May 2023

Effect of free boundary on the flow field characteristics of a single expansion nozzle has been studied experimentally and computationally. The single expansion nozzles studied in this investigation are a convergent-divergent nozzle of rectangular cross-section with convergent-divergent wall on one side and a flat wall on the opposite side, and an identical convergent-divergent ramp with its top open to atmosphere. The studies have been carried out at nozzle pressure ratios 2, 3, 4 and 5. The results show that the single expansion nozzle with wall boundary is able to deliver the flow with Mach number around 1.5, at nozzle pressure ratios of 4 and 5 even with the single expansion. The nozzle with free boundary, the wall static pressure is appreciably lower than that of nozzle with closed boundary and the exit Mach number is 1.5 for NPR 4 and 1.75 for NPR 5. That is, at the exit, the single expansion nozzle with free boundary delivers higher Mach number compared to single expansion nozzle with wall boundary for NPR 5.
Topoi and Toponyms: The Rhetoric of the City in Isa 1 and Assyrian Imperial Practices
Authors: Boyd Samuel L.
Published: May 2023

The influence of Assyrian ideology on First Isaiah has received extensive treatment over the past few decades. I present another possible datum to explain a rhetorical argument that unfolds in Isa 1:21–28 through the addition of the later supplement in vv. 29–31, namely the shift in Jerusalem from being labeled a »faithful city« to an »unfaithful city«. In light of the political grounding of the passage, the historical backdrop of the intermittent Assyrian practice of changing the toponyms of subjugated cities becomes more transparently important for unlocking the meaning and significance of this passage.
Le Psaume 79 et sa fonction dans la collection d’Asaf
Authors: Ramond Sophie
Published: May 2023

Le scénario du Ps 79 réfère à la ruine de Jérusalem et constitue un cas d’étude pour sonder la capacité des textes bibliques à parler de la souffrance. Le style anthologique et les jeux d’intertextualités plaident pour une datation tardive du psaume et suggèrent qu’il ait pour visée de concilier différentes appréciations du cours de l’histoire et du rapport de Yhwh à son peuple. Cette hypothèse trouve un appui dans le fait que le psaume est composé de trois unités, chacune ayant une perspective propre. L’ensemble de ces traits éclairent la fonction que joue ce psaume dans la collection d’Asaf.

A Study on the Perspective of Confucian Classicsby Park Jang hyun
Authors:   Institute of Korean Cultural Studies Yeungnam University, Kim Nam In
Published: May 2023

Although Park Jang-hyun lived for a short time, he stood out in the field of Confucianism and history and left many related writings. In the midst of the loss of his country, he thought about the role of intellectuals and diagnosed that his country was annexed to Japan because previous Confucian scholars did not understand the reality properly, but he saw that it was not a matter of Confucianism itself. Confucianism was not a study to be discarded, but rather an object to be restored. The problem was the attitude or interpretation of Confucian Classics. He saw that although Confucian Classics emphasizes universal truths, on the other hand, its interpretation and application should vary depending on reality and the situation of the times.
Representative sentences on the study of Park Jang-hyun's Confucian Classics abroad include “Gyeonghakdogbon” and “Samgyeongsurok”. The three Confucian Classics mentioned in “Samgyeongsurok” are “The Book of Songs”, “The Book of History” and “The Book of Changes”. These are included in the sentences of “Doksisugi”, “Doksiseogi”and “Juyeokhokmun”. Through the analysis of these three sentences, this paper attempts to analyze Park Jang-hyun's views on Confucian Classics and its interpretation.

En torno al bien común: ensayo desde el humanismo de la praxis
Authors: Kruter Flores Rafael
Published: May 2023

Bien común, común, comunes, son expresiones que en las últimas décadas han sido crecientemente utilizadas con un sentido positivo, sea en términos de alternativas a un status quo que genera problemas de diversos matices, sea para referirse a un denominador común que congrega algo que se supone deseable, utópico o no. En este ensayo, se discute el bien común haciendo un pasaje por marcos teóricos y éticos: los ‘recursos comunes agregados’, lo ‘Común’ como principio político y la ‘ética del bien común’. La discusión se fundamenta en una rememoración del Foro Social Mundial como un marco de la discusión de alternativas planetarias y universales; y del humanismo de la praxis, perspectiva filosófica y practica que se expresa en el imperativo categórico declarado por Marx en un texto clásico escrito en 1844 de ‘echar por tierra todas las relaciones en que el ser humano sea un ser humillado, sojuzgado, abandonado y despreciable’. Estos marcos posibilitan discutir el bien común desde el interrogante de potencialidades y posibilidades: el bien común, que se presenta como fenómeno categorizado como recursos comunes agregados, adquiere una existencia más profunda, radical, humana, utópica y universal cuando es pensado como ética.

Es un virus de presentación común en gatos en condiciones de albergue o gatos con acceso al exterior, el cuadro clínico está asociado con sintomatología respiratoria, ulceraciones orales, secreción ocular y cojeras. El objetivo de este estudio fue determinar la frecuencia de calicivirus felino en animales con cuadro respiratorio en la ciudad de Medellín, Colombia, en 2020. Se realizó un estudio descriptivo de corte transversal donde se incluyeron 64 gatos domésticos con sintomatología compatible con enfermedad del tracto respiratorio superior y úlceras orales para determinación de frecuencia de presentación de CVF, la distribución fue 36 hembras y 28 machos y la raza mestiza fue la más frecuente con 47 ejemplares, los cuales fueron vacunados con vacuna convencional cepa F9. Se realizaron hisopados conjuntivales y nasales para diagnóstico por reacción en cadena de la polimerasa (RCP) para detección de calicivirus felino, de los cuales 22 gatos resultaron positivos a calicivirosis felina, con una frecuencia del 34,3% de la muestra evaluada. El calicivirus felino es una enfermedad de alta frecuencia de presentación en los felinos domésticos con sintomatología respiratoria y con úlceras orales en Medellín, Colombia, inclusive en gatos vacunados con vacunas convencionales que contienen la cepa F9, lo que puede implicar que están circulando cepas que no responden a estas vacunas.
Modelling casino hospitality business cycles

Published: May 2023

This study decomposes the casino hospitality business cycles of Las Vegas and Macao into highgrowth states (HGS) and low-growth states (LGS) using a Markov switching model. The casino gaming sector in Macao experiences greater fluctuations than the sector in Las Vegas due to more volatility in tourism flows; that is, Macao has a slightly higher HGS and a considerably lower LGS than Las Vegas. Las Vegas’s hospitality cycle appears to be more robust than Macao’s, although both hospitality cycles are desirably asymmetric. Various factors, including external business cycles and supply-side factors, affect local hospitality cycles. In terms of policy suggestions, the study’s results suggest that promotional marketing must be strengthened in Las Vegas, and Macao must diversify its industrial base.
The variation in the level of the socio-economic development of the NUTS-3 subregions in the European Union
Authors: Spychała Marcin
Published: May 2023

A very important research problem is the specification of the level of the socio-economic development of the EU regions. Within the cohesion policy, one may differentiate between regions more and less advanced in terms of general development, including the worth of GDP per capita. Following that measure, one can establish the areas eligible for getting help from EU budget support programmes. The purpose of the article was to present the variation in the level of the socio-economic development of 28 EU countries within the 1,347 NUTS-3 units. The level of the development was established on a multilevel basis, subcategorising three factors of regional development: human capital, the natural environment and the economy. The article specifies the extent of the NUTS-3 unit general progression following the analysis of 31 indicative measures structured around publicly available Eurostat statistical data (as of 2019). The extent of the progression was demonstrated based on a synthetic measure revealing the taxonomic distance of a particular region from the assumed arrangement measuring the development. The research procedure consisted of five development levels, namely: the establishment of factors of the progression of regions, a choice of variable factors, a decrease in the multi-factor space, an identification in the extent of the social and economic progression of the researched units and a subcategorisation of the units on the scale of the social and economic progression structured around a ranking prepared using the analysis of a lowering synthetic measure. The research resulted in spatial variation of 1,347 NUTS-3 unit subregions in 28 EU states presented in terms of the level of the social and economic progression and the three subparts of the progression. The highest synthetic measure was noted in the areas including the capitals of the states included in the research and in a belt comprising the Irish subregions, Central England, the Benelux states, Western and Southern Germany, up until the Alpine subregion. Moreover, significant differences between the levels of the development within the respective states were presented. The results of the research may be a source of inspiration for EU institutions within the scope of the manner of specifying the richest and the poorest EU regions, whose purpose is to ensure the efficient introduction and conclusion of the cohesion policy in the programming periods specified.
A systematic review of the effects of perturbation training on preventing falls
Authors: Papadimitriou Angela , Perry Mark
Published: May 2023

Falls cause injury or death in healthy but frail older people. The efficacy of conventional falls prevention training for healthy older people may be sub-optimal, and perturbation training, a new approach that trains reflexive control of postural stability, has been evaluated in several trials. One systematic review of this new approach exists, but it included people with neurological diagnoses. The current systematic review aimed to evaluate if perturbation training can reduce falls in healthy frail older people and healthy young people. Included studies had to compare perturbation training to a control, in terms of falls incidence. Three separate protocols were devised for studies using different ages and falls outcomes. Sixteen eligible papers were found, comprising 849 participants. Perturbation training may be effective compared to no treatment in reducing laboratory-induced falls in older and younger people. Benefits may occur quickly, can be long-lived, and are generalisable. However, the efficacy of perturbation training in reducing community falls incidence in frail older people is uncertain. In all studies the quality of evidence is low to very low, and further rigorous research is required.

Sports-related concussion (SRC) is a risk across all sports. New Zealand physiotherapists are more frequently in attendance at sporting events than medical doctors. The aim of this study was to determine the knowledge, attitudes, and behaviours of physiotherapists working with SRC, using a 35-item, multi-choice questionnaire. The survey was completed by 122 physiotherapists (response rate 10%). Physiotherapists were knowledgeable regarding SRC and showed positive attitudes towards correct management of the injury. Of the respondents, 98% recognised the key signs and symptoms of SRC, and 88% would refer to a medical practitioner for further assessment of SRC. Physiotherapists indicated a strong desire to be more involved in sideline management and testing, and would like to see a more multidisciplinary approach to return-to-play decision-making after SRC. Given that the knowledge, attitudes, and behaviours of New Zealand physiotherapists to SRC were very good, it is suggested that the processes in New Zealand be reviewed to enable physiotherapists to be more involved in the assessment and management of concussion.
Caregivers’ Perspectives on Service Provision in Augmentative and Alternative Communication: A Systematic Literature Review
Authors: Filipski Madeline , Van Ert Samantha , Szydlik Theresa , Lehavi Ava
Published: May 2023

Alternative and augmentative communication (AAC) services are essential to improving communication skills in children with complex communication needs (CCN). Communication through whatever means necessary is essential for one to relate to the world and the people in it. By providing children with complex communication needs with alternative and augmentative communication services, they can communicate with caregivers, friends, and the public. Caregivers are key stakeholders in the process. As a result, a systematic literature review was conducted from 1985 to 2022 to determine caregivers’ perspectives on AAC service provision and if there were differences during assessment or identification process (pre-service), during the implementation of services (during), and during the follow-up (post-service). A total of seven studies met the inclusion criteria. Studies were thematically coded into seven overarching themes based on the findings from each included study. Results are discussed based on the timing of the service provision. Implications and future practical and research directions are outlined. This literature review found that caregivers acknowledged challenges getting involved in the initial AAC process, finding an appropriate focus for their child’s AAC interventions, promoting access and inclusion in educational settings and the community, overcoming barriers inhibiting service provision, and collaborating with service providers. These findings are particularly important for children with CCN because, to engage in the world effectively and appropriately, children and caregivers need to be equipped with all possible tools to successfully communicate.
Keywords: alternative and augmentative communication, AAC, complex communication needs, CCN, caregiver, families, and perspectives.
Can You Imagine That: Individual Differences in Visual Mental Imagery
Authors: Wong Kwan Nok Adrian , Tong Frank
Published: May 2023

Differences in mental imagery ability between individuals have been reported since Galton in 1880. Despite much progress in the mental imagery field, particularly with the advent of neuroimaging techniques like functional magnetic resonance imaging, the neural bases of mental imagery and why individual differences exist in mental imagery ability are not fully understood. Several subjective and objective methods have been proposed and utilized to investigate the strength of visual mental imagery, and even to predict the content of imagery. Recent evidence has shown that people with opposite extremes of visual mental imagery ability, aphantasia and hyperphantasia, have selective impairments and enhancements of ability to visualize visual elements in imagery. We argue that this heterogeneity is generalizable to the population who have relatively normal imagery ability. Current studies have overgeneralized specific paradigms and stimuli to apply to visual mental imagery ability of all types of stimuli, under the presumption that this ability is homogenous. Future studies would benefit from both increased granularity and expanded scope of paradigms and stimuli used.
The Effects of Anorexia Nervosa on Pregnancy
Authors: He Victoria
Published: May 2023

Anorexia nervosa is one of the most prevalent eating disorders, disproportionately affecting more women than men. It is characterized by deliberate self-starvation alongside other extreme measures to maintain an exceedingly low weight. This scientific literature review aims to analyze the effects of anorexia nervosa on pregnancy in both maternal health and perinatal health. This review addresses a gap in the current literature on maternal and perinatal health that compares pregnancies in which the mother faces active anorexia versus past anorexia. The methodology includes a search for peer-reviewed journals on anorexia in relation to pregnancy published recently from 1987 to 2020. Six research studies from the Jean and Alexander Heard Library online database were identified as relevant based on an overview of their titles, abstracts, and content. The results indicate that regarding the pregnant mother’s health, anorexia nervosa has detrimental consequences on numerous organ systems. It leads to nutritional deficiency that can result in anemia and antepartum hemorrhage, which can induce shock and death from blood loss. Regarding the fetus’ health, anorexia nervosa is positively correlated with fetal mortality. It can also lead to premature births and low gestational weights, which are associated with future cognitive impairments and memory problems. Based on an analysis of the literature, the conclusion formulates a summary of the findings, brief recommendations, and areas for future research. Due to the wide-ranging causes and effects of anorexia, the most effective treatment for pregnant women is a multidisciplinary approach combining psychotherapy, behavioral therapy, weight restoration, and family involvement.
