Imaging the seismic velocity structure of the crust and upper mantle in the northern East African Rift using Rayleigh wave tomography
Authors: Chambers Emma , Harmon Nicholas , Rychert Catherine , Gallacher Ryan , Keir Derek
Published: April 2021

Understanding the dynamics and evolution of continental rifting is broadly important for our understanding of plate tectonics. The northern East African Rift offers an excellent opportunity to study these processes at an active rift that was initiated by a large magmatic event. Multiple seismic models have been produced to understand the evolution of magmatism which image punctuated slow velocity zones in the asthenosphere. However, the depth extent of the slow velocity bodies has been less well constrained leading to much debate regarding the primary controls on melt generation. Variations between methods, resolution, and scale of the seismic models make direct quantitative comparisons challenging. The lack of instrumentation off-rift further limits our understanding of the spatial extent of tectonic and magmatic processes, which is crucial to understanding magmatic continental rifting. In this paper, we jointly invert Rayleigh wave dispersion curves from ambient noise and teleseisms to obtain absolute shear velocity maps at 10–150 km depth. This includes data from a new seismic network located on the Ethiopian Plateau and enhanced resolution at Moho and upper mantle depths from the joint inversion. At crustal depths, velocities are slowest beneath the Main Ethiopian Rift and the off-rift Ethiopian Plateau (<3.00-3.75 ±0.04 km/s, 10–40 km depth) and ongoing magmatic emplacement is required. At 60–80 km depth off-rift, we observe a fast velocity lid (>0.1 km/s faster than surroundings), in agreement with previous estimates of lithospheric thickness from receiver functions. The fast lid is not observed within the Main Ethiopian Rift or central Afar which instead are underlain by asthenospheric slow velocity anomalies (<4.05 ±0.04 km/s at 60–120 km depth). This suggests melt is infiltrating the lithosphere within the rift. Furthermore, punctuated asthenospheric slow velocity anomalies (∼110×80 km wide) exist in areas that have not undergone significant crustal and plate thinning, potentially indicating melt infiltration may start prior to significant plate deformation. Finally, the punctuated asthenospheric slow velocity zones are not located directly beneath melt-rich crustal regions including those off-rift, suggesting melt migration processes are dynamic and/or may occur laterally.
Flow and fracture of austenitic stainless steels at cryogenic temperatures
Authors: Fernández-Pisón Pilar , Rodriguez-Martinez Jose , García-Tabares E. , Avilés-Santillana I. , Sgobba S.
Published: April 2021

In this paper, we have characterized the microstructural evolution and the plastic flow and fracture behaviours of AISI 304L and AISI 316LN stainless steel grades at liquid nitrogen temperature (77 K) and at liquid helium temperature (4 K). Uninterrupted tensile experiments, where the sample is continuously deformed under quasi-static loading conditions until fracture, have been carried out with a Single-Section Sample to obtain the stress-strain characteristics of the two grades. Interrupted tensile experiments, in which the sample is unloaded before fracture, have been performed with a novel Double-Section Sample to later characterize the strain-induced martensitic transformation at different levels of deformation. The content of martensite has been determined post-mortem, using magnetic induction, electron backscatter diffraction and quantitative light optical micrography. The results obtained with the three methods show quantitative agreement, and reveal that the martensitic transformation in AISI 304L occurs faster and to a greater extent than in AISI 316LN both at 77 K and at 4 K. To the authors' knowledge, in this paper we provide the first experimental results for the evolution of the content of strain-induced martensite in AISI 304L and AISI 316LN samples tested at liquid helium temperature. In addition, the experimental data for the evolution of the martensite volume fraction with the strain have been used to identify the temperature-dependent parameters of the martensitic transformation kinetic models proposed by Olson and Cohen (1975) and Garion and Skoczen (2002). Moreover, Mode I fracture tests with fatigue-precracked Compact Samples have been carried out to determine the fracture properties of the two investigated materials using the "resistance curve procedure" (ASTM-E1820-20a, 2020). The crack-growth resistance curves have been obtained with four different methods here referred to as ASTM Compliance Method, W-N Compliance Method, Modified W-N Compliance Method and ASTM Normalization Method, which is an original methodological contribution of this paper. While the four approaches yield similar results for the fracture toughness, only the W-N Compliance Method and the Modified W-N Compliance Method, the latter being proposed in this paper, fulfil all the requirements of the standard ASTM-E1820-20a (2020) so that the calculated fracture toughness can be accepted as a material property. The comparison of results for both materials and testing temperatures shows that the AISI 316LN displays higher fracture toughness than the AISI 304L. Moreover, post-mortem microstructural analysis of the Compact Samples near the fracture surface has revealed that the content of martensite is greater in AISI 304L than in AISI 316LN. Furthermore, for AISI 304L more martensite is formed in the sample tested at 77 K because the plastic deformation near the crack is greater than at 4 K.
Does local coherence lead to targeted regressions and illusions of grammaticality?
Authors: Paape Dario , Vasishth Shravan , Engbert Ralf
Published: April 2021

Local coherence effects arise when the human sentence processor is temporarily misled by a locally grammatical but globally ungrammatical analysis ("The coach smiled at THE PLAYER TOSSED A FRISBEE by the opposing team"). It has been suggested that such effects occur either because sentence processing occurs in a bottom-up, self-organized manner rather than being under constant grammatical supervision (Tabor, Galantucci, & Richardson, 2004), or because local coherence can disrupt processing due to readers maintaining uncertainty about previous input (Levy, 2008). We report the results of an eye-tracking study in which subjects read German grammatical and ungrammatical sentences that either contained a locally coherent substring or not and gave binary grammaticality judgments. In our data, local coherence affected on-line processing immediately at the point of the manipulation. There was, however, no indication that local coherence led to illusions of grammaticality (a prediction of self-organization), and only weak, inconclusive support for local coherence leading to targeted regressions to critical context words (a prediction of the uncertain-input approach). We discuss implications for self-organized and noisy-channel models of local coherence.
Visuo-Locomotive Update in the Wild. The Role of (Un)Familiarity in Choice of Navigation Strategy, and its Application in Computational Spatial Design
Authors: Kondyli Vasiliki , Bhatt Mehul
Published: April 2021

We study active human visuo-locomotive experience in everyday navigation from the viewpoints of environmental familiarity, embodied reorientation, and (sensorimotor) spatial update. Following a naturalistic, in situ, embodied multimodal behaviour analysis method, we conclude that familiar users rely on environmental cues as a navigation-aid and exhibit proactive decision-making, whereas unfamiliar users rely on manifest cues, are late in decision-making, and show no sign of sensorimotor spatial update. Qualitative analysis reveals that both groups are able to sketch-map their route and consider path integration: i.e., conscious spatial representation updating was possible but not preferred during active navigation. Overall, the experimental task did not trigger automatic or reflexlike spatial updating, as subjects preferred strategies involving memory of perceptual cues and available manifest cues instead of relying on motor simulation and continuous spatial update. Rooted in the behavioural outcomes, we also position applications in computational modelling of navigation within cognitive technologies for architectural design synthesis.
Does an individualized learning design improve university student online learning? A randomized field experiment

Published: April 2021

University courses often employ “one-size-fits-all” approaches, disregarding the heterogeneity in students’ cognitive and motivational characteristics. This intervention study reports on an individualized learning design for online teaching in higher education. In a randomized field experiment with N = 438 university students (57% female, mean age M = 20.96 years), we investigated the effects of the learning design on students’ motivation (self-concept, self-efficacy, intrinsic and utility task values), on their performance, and, because our sample consisted of teacher students, on their professional development with regard to inclusive education. Employing structural equation modeling, we found that the intervention positively affected the self-concepts of effort avoidant students. The intervention also positively impacted students’ attitudes and self-efficacy towards inclusive education, but had no effect on course performance, course-related self-efficacy and task values. Moreover, learning analytics data revealed in-depth information on students’ learning behavior. Results are discussed regarding possible intervention strategies to be implemented in future versions of the learning design.
Balancing Bias and Burden in Personal Network Studies
Authors: Stadel Marie , Stulp Gert
Published: April 2021

Personal network data is increasingly used to answer research questions about the interplay between individuals (i.e., egos) and their social environment (i.e., alters). Researchers designing such data collections face a trade-off: When eliciting a high number of alters, study participation can be particularly burdensome as all data is obtained by surveying the ego. Eliciting a low number of alters, however, may incur bias in network characteristics. In the present study we use a sample of 701 Dutch women and their personal networks of 25 alters to investigate two strategies reducing respondent burden in personal network data collections: (1) eliciting fewer alters and (2) selecting a random subsample from the original set of elicited alters for full assessment. We present the amount of bias in structural and compositional network characteristics connected to applying these strategies as well as the potential study time gain for every possible network size (2 to 24 alters) as a proxy for respondent burden reduction. Our results can aid researchers designing a personal network study to balance respondent burden and bias in estimates for a range of compositional and structural network characteristics.
Humans as superorganisms: how microbes, viruses, imprinted genes, and other selfish entities shape our behavior
Authors: Kramer Peter , Bressan Paola
Published: April 2021

Psychologists and psychiatrists tend to be little aware that (a) microbes in our brains and guts are capable of altering our behavior; (b) viral DNA that was incorporated into our DNA millions of years ago is implicated in mental disorders; (c) many of us carry the cells of another human in our brains; and (d) under the regulation of viruslike elements, the paternally inherited and maternally inherited copies of some genes compete for domination in the offspring, on whom they have opposite physical and behavioral effects. This article provides a broad overview, aimed at a wide readership, of the consequences of our coexistence with these selfish entities. The overarching message is that we are not unitary individuals but superorganisms, built out of both human and nonhuman elements; it is their interaction that determines who we are.
Mediating role of sensory differences in the relationship between autistic traits and internalizing problems
Authors: Tsuji Yurika , Matsumoto Satoko , Saito Aya , Imaizumi Shu , Yamazaki Yoko , Kobayashi Tetsuyuki , Fujiwara Yoko , Omori Mika , Sugawara Masumi
Published: April 2021

Background: Sensory differences are related to the autistic traits, and previous studies have shown a positive correlation between sensory differences and internalizing problems. In this study, we hypothesized that sensory differences and suffering due to sensory differences mediates the relationships between autistic traits and internalizing problems. Methods: A total of 346 female Japanese university students completed questionnaires regarding their autistic traits, suffering due to sensory differences, and internalizing problems. Moreover, 114 participants completed a questionnaire related to sensory differences.Results: Autistic traits were correlated with Low Registration and Sensation Avoiding. These sensory differences were also correlated with suffering due to sensory differences and internalizing problems. Moreover, path analysis indicated that the higher the suffering due to Low Registration and Sensation Avoiding was, the greater the internalizing problems in those who showed these sensory differences.Conclusions: Female university students with serious suffering due to sensory differences may need support in managing their suffering and internalizing problems. Further research will help suggest support that these people require, at school and elsewhere.
Doing it for the team: Soccer coaches’ identity leadership predicts players’ effort, turnover intentions, and performance
Authors: Krug Henning , Haslam S. Alex , Otto Kathleen , Safi Gahis , Steffens Niklas K
Published: April 2021

Objectives: The present research investigates how coaches’ identity leadership predicts individual and team outcomes in soccer. Specifically, we tested hypotheses that coaches’ identity leadership would be associated with players’ perceptions of (a) higher team effort, (b) lower turnover intentions, (c) better individual performance, and (d) better team performance. In addition, we aimed to examine the relationship between coaches’ identity leadership and increased team identification of players and the degree to which the associations of identity leadership with these various outcomes were mediated by players’ strength of team identification.Design: We conduced a cross-sectional study of male soccer players in Germany.Method: The final sample consisted of 247 male soccer players nested in 24 teams that completed measures of their coaches’ identity leadership, team identification, team effort, turnover intentions, and individual/team performance.Results: Analysis revealed a positive relationship between coaches’ identity leadership and team effort, as well as individual and team performance. Moreover, coaches’ identity leadership was associated with lower turnover intentions. There was also evidence that the relationships between identity leadership and the investigated outcomes were mediated by team identification.Conclusions: These findings support claims that coaches’ identity leadership is associated with better individual and team outcomes because it helps to build a sense of ‘we’ and ‘us’ in the team they lead.

Published: April 2021

This research is motivated by the fact in the field that the fourth-grade students' mathematics learning outcomes are still low in Public Elementery School 16 Bengkulu City. This is presumably, the lack of application of demonstration methods and student activeness towards student learning outcomes. On this basis, this study is focused on discussing mathematics learning using demonstration methods. The problem of this research is the low student learning outcomes and the students' lack of understanding of the broad and perimeter material. The purpose of this study was to determine the effect of demonstration methods and student activeness on mathematics learning outcomes of fourth-grade students of SD Negeri 16 Bengkulu City. This type of research is a quantitative study with an experimental method approach. Data collection techniques using observation, tests and documentation. The data analysis technique used the t test. The result of this research is the demonstration method and student activeness have a significant effect. So it can be concluded that the higher the student's activity, the higher the learning outcomes and the demonstration method as well as the learning outcomes, which means that the working hypothesis (Ha) in this study is accepted, that is, there are differences in student activeness in the control and experimental classes.

Published: April 2021

Recruiting people from diverse backgrounds to participate in health research requires intentional and culture-driven strategic efforts. In this study, we utilize publicly available Twitter posts to identify targeted populations to recruit for our HIV prevention study. Natural language processing and advanced classification methods were used to find self-declarations of ethnicity, gender, age group, and sexually-explicit language. Using the official Twitter API we collected 47.4 million tweets posted over 8 months from two areas geo-centered around Los Angeles. We identified 5,392 users who are likely young Black or Hispanic men living in Los Angeles using available tools (Demographer and M3). Our automatic analysis of their timelines yielded 2,166 users posting sex-related tweets. Despite a limited precision, our results suggest that it is possible to automatically identify users based on their demographic attributes and Twitter language characteristics for enrollment into epidemiological studies.

Authors: Usul Fikriye , Kocabas Ibrahim
Published: April 2021

The aim of this research is to examine the roles and competencies of school principals working in project schools in terms of accountability, based on the views of school principals. This is a qualitative research which is based on the phenomenology design. The working group is chosen among the most well-known project schools in Istanbul using the maximum variation sampling method. Interviews were held with 12 school principals working at the Science High School, Anatolian High School, Social Sciences High School and Anatolian Religious High Schools in the 2019-2020 academic year. The data obtained from the interviews are coded using content analysis method and different 3 themes such as supervision, the functioning of education and integrity are obtained. In this context, it is indicated that project school principals felt themselves accountable most since they have a right to determine the managers and teachers they want to work with. It came to the conclusion that school principals cooperate with their internal and external stakeholders in all matters for the development of their schools.
Students as Scientists’ Co-pilots in the Onset of Technology Transfer: A Two-Way Learning Process
Authors: Giones Ferran , Kleine Kari , Tegtmeier Silke
Published: April 2021

To generate knowledge and technology transfer, universities are exploring new collaborative models. These new models aim to include actors that can have a positive impact on the technology transfer efforts of engaged academics. While open and collaborative models for technology transfer are seen as promising alternatives to the patent-centric linear model, there are limited insights on how these collaboration processes unfold and on their possible implications for the commercialization of new technologies.We explore the dynamics between the focal actor, i.e., the scientist, and a new actor in technology transfer, i.e., the students, in a university setting. We use an inductive, embedded multiple-case study to explore the contribution of knowledge interactions between scientists and students on the first steps of the technology transfer process.Our results suggest that the students’ contribution in the initial stages of the technology transfer process is influenced by the level of the scientist-student team consensus on the technology function as well as the flexibility and openness of the scientist to reconsider the technology meaning. We contribute to the ongoing debate on alternative technology transfer models and on the possible roles of students in academic ecosystems
Occupational Dualism and Intergenerational Educational Mobility in the Rural Economy: Evidence from China and India
Authors: Emran M. Shahe , Ferreira Francisco H. G. , Jiang Yajing , Sun Yan
Published: April 2021

This paper extends the Becker-Tomes model of intergenerational educational mobility to a rural economy characterized by farm-nonfarm occupational dualism and provides a comparative analysis of rural China and rural India. The model builds a micro-foundation for the widely used linear-in-levels estimating equation. Returns to education for parents and productivity of financial investment in children’s education determine relative mobility, as measured by the slope, while the intercept depends, among other factors, on the degree of persistence in nonfarm occupations. Unlike many existing studies based on coresident samples, our estimates of intergenerational mobility do not suffer from truncation bias. The sons in rural India faced lower educational mobility compared with the sons in rural China in the 1970s to 1990s. To understand the role of genetic inheritance, Altonji et al. (2005) biprobit sensitivity analysis is combined with the evidence on intergenerational correlation in cognitive ability in economics and behavioral genetics literature. The observed persistence can be due solely to genetic correlations in China, but not in India. Father’s nonfarm occupation was complementary to his education in determining a sons’ schooling in India, but separable in China. There is evidence of emerging complementarity for the younger cohorts in rural China. Structural change in favor of the nonfarm sector contributed to educational inequality in rural India. Evidence from supplementary data on economic mechanisms suggests that the model provides plausible explanations for the contrasting roles of occupational dualism in intergenerational educational mobility in rural India and rural China.

American Exceptionalism: Determinants of spreading COVID-19 misinformation online in five countries
Authors: Pickup Mark , Stecula Dominik , van der Linden Clifton
Published: April 2021

Social media have long been considered a venue in which conspiracy theories originate and spread. It has been no different during COVID-19. However, understanding who spreads conspiracy theories by sharing them on social media, and why, has been underexplored, especially in a cross-national context. The global nature of the novel coronavirus pandemic presents a unique opportunity to understand the exposure and sharing of the same COVID-19 related conspiracies across multiple countries. We rely on large, nationally representative surveys conducted in July of 2020 in the United States, United Kingdom, Canada, Australia, and New Zealand, to begin to understand who shares conspiracies on social media and what motivates them. We find that Americans are no more likely to encounter prominent COVID-19 conspiracies on social media but are considerably more likely to subsequently share them. In all countries, trust in information from social media predicts conspiracy theory sharing, while in the US politics plays a unique role Our results make clear that American behavior on social media has the potential to poison online public discourse globally.
The Accurate Assessment of Muscle Excitation Requires the Detection of Multiple Surface Electromyograms
Authors: Vieira Taian Martins , Botter Alberto
Published: April 2021

When sampling electromyograms (EMGs) with one pair of electrodes, it seems implicitly assumed the detected signal reflects the net muscle excitation. However, this assumption is discredited by observations of local muscle excitation. Therefore, we hypothesize that the accurate assessment of muscle excitation requires multiple EMG detection and consideration of electrode-fiber alignment. We advise prudence when drawing inferences from individually collected EMGs

Sektor zdravstva prošao je kroz brojne promjene posljednjih desetljeća koje su dovele do niza novih opasnosti za zdravlje medicinskih sestara, ali i novih izazova koje područje sigurnosti i zdravlja na radu treba savladati. Medicinske sestre čine najbrojniju skupinu zdravstvenih djelatnika, a zbog prirode svojeg posla izložene su velikom broju potencijalno opasnih situacija i tvari. Profesija medicinskih sestara karakterizirana je visokim osjećajem osobnog zadovoljstva i postignuća. No, dinamična radna okolina u kojoj sudjeluju različiti profili djelatnika te visoko specijalizirana tehnologija mogu predstavljati značajan rizik za njihovo zdravlje, a zdrave medicinske sestre neophodne su za pružanje kvalitetne skrbi bolesnicima.
Cilj ovoga rada je prikazati najvažnije kritične točke rizika od ozljeda na radu medicinskih sestara što uključuje različite stresore povezane s izravnom skrbi za bolesnika kao što su ergonomski, biološki, kemijski, fizički i psihosocijalni rizici u radu medicinskih sestara. Podaci za analizu dobiveni su pregledom dostupne literature u Hrvatskoj, Europi i svijetu pretraživanjem baza podataka PubMed, Google Scholar, Elseviar, UpToDate te drugih izvora na temelju ključnih riječi u razdoblju od 2000. do 2019. godine.
Iz pregleda literature vidljivo je kako je područje sigurnosti i zdravlja medicinskih sestara na radu vrlo složeno te zahtijeva dubinsku analizu i identifikaciju rizika i osoba pod rizikom, evaluaciju rizika i određivanje prioriteta, planiranje preventivnih akcija, provođenje akcija te dokumentiranje, praćenje i provjeru rezultata.

Psychometric properties and diagnostic criteria of Scale for the assessment of negative symptoms (SANS) in schizophrenia
Authors: Assanovich M. V. , Karpiuk V. A.
Published: April 2021

The Scale for the assessment of negative symptoms (SANS) is one of the most widely used clinical assessment tools for negative symptoms.

Thepurposeof this study was psychometric analysis and modification of the SANS with the definition of criteria for assessing the severity of negative symptoms in the dynamics of therapy in patients with schizophrenia.

Materialandmethods:The study involved 157 patients with a diagnosis of schizophrenia, the age range of participants ranged from 18 to 59 years. Psychometric analysis was done on the base of the Rush measurement with the definition of criteria for assessing the severity of negative symptoms based on the index of minimum detectable changes for 95% probability (Minimum detectable change95%— MDC95%).

Results:Five SANS diagnostic items with low construct validity were identified. The technique was modified by excluding these invalid items. SANS was modified by eliminating of 5 invalid items. The modified version of SANS demonstrated high reliability (reliability index = 0.97) and discriminativeness (the ability to differentiate 12 metric levels of severity of negative symptoms). Factor analysis revealed the heterogeneity of the metric structure of the technique: points in the first group reflect the impoverishment of speech and emotional manifestations, points in the second group reflect the decrease of the patient’s involvement in various activities and restriction of social interaction. Thus, the two-dimensional structure of the SANS scale (“expression” factor and “motivation” factor) is fully consistent with the modern concept of negative symptoms, which allows to consider the total SANS score as an indicator of the severity of the negative syndrome construct. In the course of the metric analysis, the criteria for assessing the severity of negative symptoms in the dynamics of the therapy were determined.

Conclusion:The modified version of SANS has adequate psychometric characteristics. The diagnostic criteria are suitable for use in clinical practice and research.

Quality of life indicators (QL) of patients are widely used in dermatological practice, but the influence of depressive and dissomnic symptoms on QL of patients with gender differences is not sufficiently studied.

Objective:to identify depressive and dissominal symptoms in patients with psoriasis and evaluate its impact on the quality of life of these patients taking into account gender differences.

Materialsandmethods:34 patients with psoriasis were examined. Clinical examination included: analysis of complaints, medical history, assessment of dermatological status. Diagnosis of the presence and severity of depression was performed using a PHQ-9 patient health rating scale. Dissominal symptoms in patients with psoriasis were determined using the index of severity of insomnia ISI. To assess the quality of life, a dermatological index of quality of life (DLQI) was used.

Resultsanddiscussion.Sleep disorders were detected in 15 patients (44.1%), depressive symptoms were determined in all patients, a negative effect of the disease on the quality of life of patients was found in 32 people (94.1%).Correlation analysis of data from the entire population of patients revealed statistically significant correlations of DLQI with the severity of depressive symptoms (r = 0.45, p = 0.008) and sleep disorders (r = 0.35, p = 0.04). In women, DLQI significantly correlates with the severity of depression (r = 0.48, p = 0.04) and tends to be associated with sleep disturbances (r = 0.43, p = 0.07). In men, the relationship between DLQI and indicators of depression and sleep disturbances is significantly weaker and is not statistically significant ((r = 0.34, p = 0.22) and (r = 0.17, p = 0.55), respectively).

Conclusion.depressive symptoms and sleep disorders are interrelated with the quality of life of patients with psoriasis, and this relationship is more pronounced in women. Consequently, it is advisable to include effects aimed at normalizing mood and sleep in the program of complex therapy of psoriasis, taking into account gender differences.

The article reflects the results of the work of the psychiatric and psychotherapy services of the Hospital for war veterans converted into an infectious hospital in the context of the new coronavirus infection (COVID-19) pandemic. The aim of our study was to determine the frequency and nature of mental disorders in patients treated in hospital for a new coronavirus infection (COVID-19) between April and June 2020. The case histories of patients who received psychotherapy or psychiatric care in addition to the treatment of the underlying disease were studied retrospectively. The study included 557 patients, 266 men, 291 women, the average age was 62.36+18.65 years. The work used clinical and psychological methods using the international classification of diseases 10 revision (ICD-10), the diagnosis of a new coronavirus infection (COVID — 19) was carried out in accordance with the Temporary guidelines of the Ministry of health of the Russian Federation. As a result of data evaluation, it was revealed that the proportion of patients requiring consultation or treatment by a psychiatrist or psychotherapist was 557 (7,10%) patients of the total number of hospital admissions, of which emergency psychiatric care was indicated in 58 (10,41%) of cases. The transition of the hospital to an infectious diseases hospital mode has set new challenges for the psychiatric and psychotherapy service, which required organizational measures, therapeutic issues and confirmed the need for participation of mental health specialists in providing full-fledged medical care in the treatment of somatic disorders.

Online sexual experiences and relationship functioning in long distance relationships
Authors: Kafaee Nazanin , Kohut Taylor
Published: April 2021

Over the past decade, research has sought to understand sexting behaviour among adolescents and young adults. Much of this work is atheoretical and harm-focused, and little research has investigated these behaviours in the context of committed adult romantic relationships. The current study seeks to understand sexting behaviours of adult long distance couples. The context of long distance relationships (LDRs) may be especially relevant for understanding the potential relational benefits of sexting because romantic partners usually have restricted opportunities to experience physical intimacy in this type of relationship. Adopting the intimacy process model as a guiding theoretical framework, we expected to find higher levels of perceived interpersonal closeness, sexual communication, and relationship and sexual satisfaction among long distance couples who practice sexting than those who do not. Results of the study, however, indicated no association between the frequency of sexting and interpersonal closeness among long distance couples. Consistent with our hypothesis, higher levels of sexual communication, relationship and sexual satisfaction were found to be correlated with more frequent sexting practices among these couples. The discussion concerns important theoretical distinctions between sexual communication and the frequency of sexting. Future research should carefully consider how sexual communication is expressed both within and outside of sexting encounters when investigating the role of sexting within LDRs.
