İran ve Suudi Arabistan Rekabetinin İsrail ve Filistin Sorunu Üzerinden Analizi
Authors: KOÇ Engin
Published: October 2020

Bu çalışmada İran ve Suudi Arabistan arasındaki ikili ilişkiler İsrail ve Filistin Sorunu üzerinden incelenmektedir. İran ve Suudi Arabistan, Orta Doğu ve İslam Dünyasında Filistin Meselesine benzer birçok noktada uzun süredir rekabet etmektedirler. İsrail'in varlığı ve yürütülen ilişkiler bölgesel devletler için büyük tartışmaları ortaya çıkarmıştır. İsrail’i bazı devletler bölgesel bir aktör olarak tanımlarken, bazı devletler ise meşru bir devlet olarak kabul etmemektedirler. İran Devrimi sonrası yeni rejimin öncelikli hedefi İsrail aleyhtarlığı olmuş ve Filistin Sorunu İran’ın Ortadoğu’da ki nüfuzunun yayılması için kullanılmıştır. Suudi Arabistan ise, İran’ın Filistin ve Lübnan’daki etkisinin sınırlandırılmasında İsrail’i caydırıcı bir aktör olarak görmüştür. Bu çalışma, İran ve Suudi Arabistan’ın İsrail ve Filistin Meselesi üzerinden birbirlerini ötekileştirme çabalarını analiz etmektedir. Bu çalışmanın temel argümanı, İran ve Suudi Arabistan’ın yoğun rekabeti yalnızca birbirlerini zayıflatmakla kalmayıp aynı zamanda İsrail’in Orta Doğu’daki konumunu güçlendirmektedir.

Authors: Marrquez Ibarra Adriana Alejandra , González Ponce Ana Maria
Published: October 2020

Introducción: Se ha demostrado que existe un componente inflamatorio en la patogenia de la diabetes tipo 2 (DM2) y se ha asociado con elevaciones en los niveles de ferritina sérica. El objetivo fue evaluar la asociación entre concentraciones séricas de ferritina, CRP, receptores solubles de transferrina (sTfR) y hemoglobina glucosilada (HbA1c) en sujetos con y sin diabetes tipo 2. Metodología: Estudio secundario, derivado de la ENSANUT 2006. Se analizaron concentraciones de ferritina, sTFR y CRP (n=4578), se asoció HbA1c y ferritina (n=287), y variables como, índice de masa corporal (IMC), edad, sexo, tratamiento actual para DM2, tabaquismo y consumo de alcohol. El análisis estadístico se realizó con modelos de regresión logística múltiple y modelos de regresión lineal múltiple. Se consideró como significancia estadística un valor de p <0.05 y la dirección y magnitud de la asociación. Resultados: La posibilidad de tener DM2 se asoció con las concentraciones séricas de ferritina y con las de CRP (p<0.02). La ferritina se asoció de manera inversa con las de sTFR (β -0.91, p<0.001). La HbA1c no se asoció con la ferritina. Conclusiones: En mexicanos con DM2 la ferritina sérica es mayor que en sujetos sin diabetes y su variabilidad está explicada por indicadores del estatus de hierro y de inflamación.Palabras clave: Diabetes tipo 2, inflamación, proteína c- reactiva, ferritina.

Authors: ANJOS BASTOS ANDREIA , XYPAS CONSTANTIN , DILSON BESERRA CAVALCANTI JOS
Published: October 2020

Inspirando-se da obra de Charlot, o NUPERES está realizando pesquisas sobre a relação ao saber de professores de ciências e matemática de origem popular. Eles têm a particularidade de pertencer a famílias privadas de capital cultural e econômico, no sentido de Bourdieu, mas cuja relação ao saber levou ao sucesso nos estudos, até o mestrado e o doutorado. Diante desses fatos, estudamos o caso de João, filho de pais semi-analfabetos, que se tornou doutor em matemática aos 27 anos e professor efetivo de uma Universidade Federal aos 28 anos. Resultados e discussâo: embora os pais semi-analfabetos não pudessem transmitir um habitus escolar, conseguiram estimular em seu filho uma relação ambiciosa ao saber acedêmico que foi então construída gradualmente através de quatro níveis.

Authors: MARINHO DA SILVA CRISTIANO , ANAHI DA SILVA VELEIDA
Published: October 2020

O objetivo do trabalho foi fazer um levantamento das situações de fracasso escolar vivenciadas por uma turma de estudantes de licenciatura em matemática em momentos “escolares” anteriores à pesquisa, na perspectiva de estabelecer relações entre os percalços vividos na Educação Básica e suas implicações no Ensino Superior. A coleta de dados se deu à partir de dissertações sobre situações de fracasso escolar vivenciadas pelos estudantes na Educação Básica e no Ensino Superior e, além disso, o relato das atitudes tomadas para superação dessas situações. A análise dos dados se baseou em Bardin (2016). Após categorização e análise dos dados concluímos que as situações de fracasso escolar são diversas com atribuição de motivos e causas diferentes; e que a mudança de postura em relação ao processo educativo, a ajuda de terceiros e a busca por meios/recursos/ferramentas diferentes proporciona maiores chances de superação das situações de fracasso.

Published: October 2020

Background

Although impaired arterial function has been associated with adverse prognosis in chronic Heart Failure (HF), its role in Acute HF Syndromes (AHFS) has been little studied. We prospectively investigated the prognostic role of arterial function on mortality and HF Hospitalizations (HHF) in patients with AHFS.

Design and Methods

A thorough assessment of arterial function was performed in patients hospitalized for AHFS 24–48 h before discharge and followed-up for 6 months for all-cause death and HHF. MAGGIC risk score was used to evaluate the additive predictive value of vascular biomarkers for clinical events.

Results

One-hundred patients were studied; aged 70 ± 11 years, 78% males, 61% had left ventricular ejection fraction ≤40% and 24% ≥50%. Mean aortic Pulse Wave Velocity (PWV) was 11.2 m/s, mean augmentation index 21% and median brachial flow-mediated dilation 3.14%. Higher PWV was associated with all-cause mortality (Hazard Ratio [HR] 1.32 per 1 m/s, p < 0.001) and the combined clinical event of mortality and HHF (HR 1.12 per 1 m/s, p = 0.012) even after adjustment for MAGGIC score. MAGGIC score predicted mortality (HR 3.40 per group increase, Area under Curve [AUC] = 0.741, p = 0.017) in our population; addition of PWV to MAGGIC score increased the predictive accuracy (AUC = 0.911, C-statistic p < 0.01 vs. MAGGIC score alone) for mortality.

Conclusion

In these AHFS patients, increased aortic stiffness was independently associated with mortality and further improved the predictive accuracy of an established risk model. Further research is needed to show whether a comprehensive assessment of AHFS patients focusing both on cardiac and vascular function, may improve management and ameliorate prognosis following an AHF hospitalization.

Published: October 2020

Objective The brain-derived neurotrophic factor (BDNF) Val66Met (rs6265) polymorphism is suggested to be associated with the pathophysiology of anxiety disorders, including panic disorder (PD). Although the fronto-limbic white matter (WM) microstructures have been investigated, the corpus callosum (CC) has not yet been studied regarding its relationship with BDNF Val66Met polymorphism in PD.Methods Ninety-five PD patients were enrolled. The Neuroticism, the Anxiety Sensitivity Inventory-Revised, Panic Disorder Severity Scale, and Beck Depression Inventory-II (BDI-II) were administered. Voxel-wise statistical analysis of diffusion tensor imaging data was performed within the CC regions using Tract-Based Spatial Statistics.Results The GG genotype in BDNF Val66Met polymorphism has significantly higher fractional anisotropy (FA) values of the body and splenium of the CC, neuroticism and depressive symptom scale scores than the non-GG genotype in PD. The FA values of the body of the CC in the two groups were significantly different independent of age, sex, neuroticism, and BDI-II.Conclusion Our findings demonstrate that the BDNF Val66Met polymorphism is associated with WM connectivity of the body and splenium of the CC, and may be related to neuroticism and depressive symptoms in PD. Additionally, the CC connectivity according to BDNF polymorphism may play a role in the pathophysiology of PD.

People’s views on polygamy are diverse, there are those who agree, but there are also those who disagree or oppose even more for women who feel disadvantaged, because they have to share with others. This is influenced by the family economy which does not allow polygamy. Such allegations eventually feel unsatisfied with suspection and even challenge qath’i syar’i texts with interpretations that are far from the elements of truth. So that legal issues are interpreted with multiple interpretations and cause vague and vague issues.

Bayi Tabung Dalam Tinjauan Hukum Islam (Analisis Maqashid Syari’ah)
Authors: Dongoran Irham
Published: October 2020

In every era, there are always social phenomena that arise, and Islamic law has covered and answered them for their legal position. One of the examples of the phenomena is IVF (In Vitro Fertilization), which is an artificial insemination as a shortcut to get children by bringing together sperm cells and egg cells outside the body which are then inserted into the mother's womb, so they can grow into a fetus as usual pregnancy. In this IVF process, there are likely to be 5 parties involved, namely: husband, wife, sperm donor, ovum donor and uterine mother. If there is a third party besides wife and husband involved in the process of IVF, there will be indications of genetic mixing in the fetus.

IVF with a system without any third party involvement (sperm and ovum from husband and wife) by transferring into the womb of the wife is permissible and the baby is the descendant of his parents. However, if there is involvement of a third party, it is prohibited. IVF In the concept of Maqashid Shari'ah is one of the media that contributes in realizing 1. Hifdzu ad-din (protecting religion), 2. Hifdzu an-nafs (protecting souls), 3. Hifdzu al-aql (protecting the mind), 4. Hifdzu al-mal (protecting property), 5. Hifdzu an-nasab (protecting descendants). However, IVF is more dominant and looks more transparent in the aspect of Hifdzu an-nasab (protecting desdendants).

Published: October 2020

Птицеводство — одна из самых интенсивно развивающихся отраслей сельского хозяйства, в которой очень актуален вопрос использования новых экологически чистых компонентов комбикормов с высокой биологической ценностью. Опыт проведен на одной из птицефабрик Краснодарского края. Для постановки эксперимента методом пар-аналогов отбирали 3 группы цыплят-бройлеров кросса КОББ-500, содержащихся в клеточных батареях. Скармливание иловой кормовой добавки способствовало увеличению валового прироста опытных бройлеров, среднесуточных приростов живой массы цыплят на 2,0 %. Наиболее высокая сохранность поголовья была в опытных группах — 96,0 %; в контрольной группе — 88,0 %. Затраты корма в опытных группах были ниже на 0,5 % по сравнению с контролем. Включение иловой добавки в рационы мясных цыплят способствовало улучшению состава микрофлоры кишечника (снижение уровня содержания стафилококков, энтерококков, плесеней в слепых отростках опытной птицы) и не оказывала отрицательного воздействия на физиологическое состояние птицы.

Authors: AKTUNA BELGİN Ceren , SERİNDERE Gözde
Published: October 2020

Objective: The nasopalatine canal (NPC) is one of the important anatomic structures in anterior maxilla. The aim of this study was to evaluate the changes in NPC morphology according to dentition status in the maxillary anterior region by computed tomography (CT).
Methods: Computed tomography images of 100 patients were screened retrospectively. Images were divided into two groups by dental status: an edentulous group (EG) of 50 patients who have edentulous premaxilla and a control group (CG) of 50 patients who have all incisor teeth in the premaxillary region. After recording the age, sex, and dentition status of the patients, the NPC diameter, NPC length, incisive foramen (IF) diameter, and angle between the NPC and palatine bone were measured in sagittal sections, and the number of NPCs was determined in axial sections.
Results: There was no significant difference between NPC angle and dentition status (p=0.151). The NPC diameter was significantly higher in the EG (p=0.002), as was the IF diameter (p=0.041). In addition, NPC length was significantly higher in the CG (p<0.001). A statistically significant and negative correlation was found between age and NPC length (p<0.001), and a positive correlation was found between age and NPC diameter (p=0.004). In addition, no statistically significant difference was found between sex and other parameters (p>0.05).
Conclusion: The NPC length and diameter vary according to the age and dentition status of the patient. Changes in this anatomic structure should be evaluated pre-operatively in elderly patients by three-dimensional radiographic evaluation.
A Comparative Clinicopathologic Analysis of Tonsillectomy and Adenoidectomy Cases: A Retrospective Study
Authors: YAPRAK BAYRAK Büşra , MUTLU Fatih
Published: October 2020

Objective: In this retrospective study, we aimed to determine the rate of malignancy detected in patients who underwent tonsillectomy, adenoidectomy or adenotonsillectomy in our clinic, and to correlate the clinical findings of adults and children by giving their histopathological analysis.
Methods: Histopathological specimens of 288 adenoidectomy, tonsillectomy and adenotonsillectomy cases operated in our clinic between years of 2017-2019 were collected retrospectively and re-evaluated with clinical data.
Results: Malignancy was suspected clinically in 12.8% (n=37) of all cases, and most of them (n=33) were in tonsillectomy group. Although reactive lymphoid hyperplasia was a common diagnosis among all cases (92.7%), 11 (3.8%) patients were diagnosed as a benign/malign neoplasm. The malignancy rate among all cases was found to be 2.1% (6/288), among tonsillectomy cases was 8.8% (6/68). All malignancies were detected among tonsillectomy cases in adults.
Conclusion: This retrospective analysis of adenotonsillar surgeries correlated with histopathological findings showed that the incidence of tonsil neoplasm in adult patients is higher than the previously published data. In the tonsillar tissues presenting with a surgical indication of clinical suspicion for malignancy such as ulceration and necrosis, and of enlargement of tonsils, a histopathological evaluation are obviously warranted. These results are in agreement with that a routine histopathological examination is needed to be regardless of the clinically presence of high malignancy suspicion prior to tonsillectomy in adults.An Erratum to this article was published on 05 January 2021. https://dergipark.org.tr/en/pub/kusbed/issue/59476/854715

Published: October 2020

Amaç: Koroner arter cerrahisinde greft açık kalma süresi endotel fonksiyonuna bağlıdır. Nitrik Oksitin (NO) endotel fonksiyonuna yararlı etkisi bilinmektedir. Greftlerdeki Nitrik Oksit düzeyi ve Losartan’ın Nitrik Oksit üzerine etkisi invitro olarak araştırılmıştır.
Yöntem: Çalışma 13 hasta da 78 örnek ile yapıldı. İnternaltorasik arter, radial arter ve safenvengreft örnekleri “Kontrol Grubu” ve “Losartan Grubu” olmak üzere ikiye ayrıldı. Losartan grubu örnekleri 1 x 10-5molar Losantanlı Troyde’s solüsyonu çözeltisi içinde inkübe edildi. Nitrik Oksit, Griess yöntemi kullanılarak ölçüldü. İstatistiksel değerlendirme. Kruskal Wallis Oneway ANOVA, İndependentsample T ile Tukey ve Bonferroni testleri kullanılarak yapıldı.
Bulgular: Kontrol grubu bazal Nitrik Oksit değeri, internaltorasik arter greftinde anlamlı olarak yüksek bulunmuştur (p<0,05). Losartan grubu internal torasik arter ve radial arter greftlerinde Nitrik Oksit artışı anlamlı değildir.
Sonuç: İnternal torasik arter en uzun açık kalma süresine sahip greftir, çünkü endotelinde Nitrik Oksit düzeyi yüksektir. Spasmolitik ilaçların kullanımı da greft açık kalma süresini olumlu etkiler. Losartan İnternal torasik arter ve radial arterlerde Nitrik Oksit düzeyini artırması olumludur fakat yeni çalışmalarla da desteklenmelidir.

Middle-aged people and the elderly have the similar risk of death from Covid-19: considering background mortality
Authors: XU ZHONGNENG
Published: October 2020

In USA, middle-aged people might be evaluated as having a low risk of Covid-19 death, but if the natural mortality is considered, the age distribution of death risk from Covid-19 changes. The proportions of Covid-19 deaths in total deaths among middle-aged and elderly people are in the same cluster. This shows that the increase rates in deaths caused by Covid-19 to middle-aged people is similar to that of the elderly, and it is necessary to pay the same attention to the risk of Covid-19 death in middle-aged people.

How do archaeologists write about racism? Computational text analysis of 41 years of Society of American Archaeology Annual Meeting Abstracts
Authors: Park Gayoung , Wang Li-Ying , Marwick Ben
Published: October 2020

Many communities and organisations responded to the murder of George Floyd in May 2020 with discussions to address systematic and institutionalized racism. We ask how often, and in what contexts, archaeologists have discussed racism over the last 41 years. Do social events lead to enduring discussions of racism in academic communities? We apply computational text analysis methods to 68,176 abstracts from 41 meetings of the Society of American Archaeology (SAA). We find discussions of racism are rare, usually as a passing mention with a suite of broad social issues. Racism is most frequently discussed by historical archaeologists.
Propulsion for Spacecrafts using on- board Laser Reflection and Absorption
Authors: Adhlakha Jivesh
Published: October 2020

In this paper, a new laser-based, on-board propulsion system has been produced. This system utilizes Laser reflection and absorption to obtain a net momentum. The proposed system is also unique in the sense that no on-board propellant is required. Further, the power consumed can be ideally recycled 100%. This makes it a viable mode of propulsion for long distance trips to planets or solar systems. Further, it has been calculated that depending upon the lasers used, this system can propel a 4000kg spacecraft with an acceleration of 100-10000 ms-2. This means, a 4000kg mass can be propelled to one-third the speed of light in just 5*104seconds, or 13.8 hours roughly. This is a big jump from current technology,which cannot achieve sub-luminal speeds, that too so quickly. This makes this system of propulsion our best bet for sub-solar system travel. Further, the setup proposed is expected to be improved.
An Investigation of the Slope Parameters of Reaction Times and P3 Latencies in the Sternberg Memory Scanning Task – A Fixed-Links Model Approach

Published: October 2020

The speed of retrieving information from short-term memory is thought to be captured in the slope of the linear function of reaction times (RTs) regressed on set size in the Sternberg memory scanning task (SMST). Individual differences in the slope parameter have been hypothesized to correlate with general intelligence (g). However, this correlation can usually not be found. This present study chose a fixed-links model (FLM) approach to re-evaluate the RT slope parameter on a latent level in a sample of 98 participants aged 18 to 61 years. The same was tried for P3 latencies to investigate whether or not both parameters measure the same cognitive processes in the SMST, and to assess the usability of both slopes to predict g. For RTs, a linear increase with set size was found. The RT slope correlated with g on a manifest level already. The FLM approach could significantly increase the relationship between the slope and g. For P3 latencies, no evidence for a linear increase was found. This indicates that RTs and P3 latencies do not measure the same cognitive processes in the SMST. The FLM proved suitable to investigate the association between the speed of short-term memory scanning and intelligence.

Several outbreak prediction models for COVID-19 are being used by officials around the world to make informed-decisions and enforce relevant control measures. Among the standard models for COVID-19 global pandemic prediction, simple epidemiological and statistical models have received more attention by authorities, and they are popular in the media. Due to a high level of uncertainty and lack of essential data, standard models have shown low accuracy for long-term prediction. Although the literature includes several attempts to address this issue, the essential generalization and robustness abilities of existing models needs to be improved. This paper presents a comparative analysis of machine learning and soft computing models to predict the COVID-19 outbreak as an alternative to SIR and SEIR models. Among a wide range of machine learning models investigated, two models showed promising results (i.e., multi-layered perceptron, MLP, and adaptive network-based fuzzy inference system, ANFIS). Based on the results reported here, and due to the highly complex nature of the COVID-19 outbreak and variation in its behavior from nation-to-nation, this study suggests machine learning as an effective tool to model the outbreak. This paper provides an initial benchmarking to demonstrate the potential of machine learning for future research. Paper further suggests that real novelty in outbreak prediction can be realized through integrating machine learning and SEIR models.
Eye tracking and cardiovascular measurement to assess and improve sporting performance

Published: October 2020

One of the difficulties of working in applied sports psychology is the lack of objective data to help understand the psychological components of an athlete’s performance (Watson & Coker-Cranney, 2018). This may be one of the primary explanations for the disparity between how important coaches and athletes report psychological elements of elite performance and how much they invest in tracking and supporting such elements (Pain and Harwood, 2004). In this chapter, we discuss two objective psychophysiological measures which provide valuable insight into the psychology of performing under pressure in elite sports, and can address the need for objective data to support athlete performance. Both measures – eye tracking and cardiovascular reactivity – have considerable evidence underpinning their efficacy in research environments (e.g. Kredel, Vater, Klostermann, & Hossner, 2017; Moore, Vine, Wilson, & Freeman, 2012). We discuss some practical issues that require consideration when using such measures in applied sports settings and report a case study.

Machine learning techniques have realized some principal cognitive functionalities such as nonlinear generalization and causal model construction, as far as huge amount of data are available. A next frontier for cognitive modelling would be the ability of humans to transfer past knowledge to novel, ongoing experience, making analogies from the known to the unknown. Novel metaphor comprehension may be considered as an example of such transfer learning and analogical reasoning that can be empirically tested in a relatively straightforward way. Based on some concepts inherent in category theory, we implement a model of metaphor comprehension called the theory of indeterminate natural transformation (TINT), and test its descriptive validity of humans' metaphor comprehension. We simulate metaphor comprehension with two models: one being structure-ignoring, and the other being structure-respecting. The former is a sub-TINT model, while the latter is the minimal-TINT model. As the required input to the TINT models, we gathered the association data from human participants to construct the ``latent category'' for TINT, which is a complete weighted directed graph. To test the validity of metaphor comprehension by the TINT models, we conducted an experiment that examines how humans comprehend a metaphor. While the sub-TINT does not show any significant correlation, the minimal-TINT shows significant correlations with the human data. It suggests that we can capture metaphor comprehension processes in a quite bottom-up manner realized by TINT.
The impact of patient narratives on medical students’ perceptions of shared decision making: A randomized controlled trial
Authors: Bientzle Martina , Eggeling Marie , Korger Simone , Kimmerle Joachim
Published: October 2020

BACKGROUND: Successful shared decision making (SDM) in clinical practice requires that future clinicians learn to appreciate the value of patient participation as early as in their medical training. Narratives, such as patient testimonials, have been successfully used to support patients’ decision-making process. Previous research suggests that narratives may also be used for increasing clinicians’ empathy and responsiveness in medical consultations. However, so far, no studies have investigated the benefits of narratives for conveying the relevance of SDM to medical students.METHODS: In this randomized controlled experiment, N = 167 medical students were put into a scenario where they prepared for medical consultation with a patient having Parkinson disease. After receiving general information, participants read either a narrative patient testimonial or a fact-based information text. We measured their perceptions of SDM, their control preferences (i.e., their priorities as to who should make the decision), and the time they intended to spend for the consultation.RESULTS: Participants in the narrative patient testimonial condition referred more strongly to the patient as the one who should make decisions than participants who read the information text. Participants who read the patient narrative also considered SDM in situations with more than one treatment option to be more important than participants in the information text condition. There were no group differences regarding their control preferences. Participants who read the patient testimonial indicated that they would schedule more time for the consultation.CONCLUSIONS: These findings show that narratives can potentially be useful for imparting the relevance of SDM and patient-centered values to medical students. We discuss possible causes of this effect and implications for training and future research.

Familiar music facilitates memory retrieval in adults with dementia. However, mechanisms behind this effect, and its generality, are unclear because of a lack of parallel work in healthy aging. Exposure to familiar music enhances spontaneous recall of memories directly cued by the music, but it is unknown whether such effects extend to deliberate recall more generally — e.g., to memories not directly linked to the music being played. It is also unclear whether familiar music cues boost recall of specific episodes versus more generalized semantic memories, or whether effects are driven by domain-general mechanisms (e.g., improved mood). In a registered report study, we examined effects of familiar music on deliberate recall in healthy adults ages 65-80 years old (N=75) by presenting familiar music from earlier in life, unfamiliar music, and non-musical audio clips across three sessions. After each clip, we assessed free recall of remote memories for pre-selected events. Contrary to hypotheses we found no effects of music exposure on recall of prompted events, though familiar music evoked spontaneous memories most often. These results suggest that effects of familiar music on recall may be limited to memories specifically evoked in response to the music (Preprint and registered report protocol at https://osf.io/kjnwd/).
I Need Help, not Likes: Review of Models to Detect Depression through Social Media Data
Authors: Agarwal Ajay
Published: October 2020

Mental health is one of the most pressing challenges that we as humans are facing today. Despite the presence of various resources to detect and diagnose mental disorders, it continues to be an issue for a significant proportion of the world. Researchers are now exploring the application of natural language processing and deep learning on the diagnosis of these disorders.However, due to the lack of a systematic and organized set of data to train upon, many of them have often failed. In this review paper, we explore prominent techniques to diagnose a specific mental disorder – Depression. We analyze and review the work done in the field of depression detection from feeds of social media platforms. For our study, we investigated mainly 3 platforms – Facebook, Twitter, and Reddit.In the later sections of the paper, we aim to analyze another pressing topic of our study- The suitability of Social Media sources to act as data resources for the diagnostic tasks for mental health disorders. As the inclination of society towards social media increases, it evolves to become a better and robust outlet for people’s emotions and expressions. Whilst recording and obtaining logs of a particular patient’s visit with the therapist might be a more accurate description, however, it is one that is usually untimely and unlikely to be formally organized. In such scenarios, a patient’s posts on various social media platforms and his activity on the same provide a better turn of perspective to solve such problems.
