Detecting Mental Disorders in Social Media Through Emotional Patterns - The Case of Anorexia and Depression

Millions of people around the world are affected by one or more mental disorders that interfere in their thinking and behavior. A timely detection of these issues is challenging but crucial, since it could open the possibility to offer help to people before the illness gets worse. One alternative to accomplish this is to monitor how people express themselves, that is for example what and how they write, or even a step further, what emotions they express in their social media communications. In this article, we analyze two computational representations that aim to model the presence and changes of the emotions expressed by social media users. In our evaluation we use two recent public data sets for two important mental disorders: Depression and Anorexia. The obtained results suggest that the presence and variability of emotions, captured by the proposed representations, allow to highlight important information about social media users suffering from depression or anorexia. Furthermore, the fusion of both representations can boost the performance, equalling the best reported approach for depression and barely behind the top performer for anorexia by only 1 percent. Moreover, these representations open the possibility to add some interpretability to the results.
Artificial Neural Network Performance Boost using Probabilistic Recovery with Fast Cascade Training

Pattern Recognition and Classification is considered one of the most promising applications in the scientific field of Artificial Neural Networks (ANN). However, regardless of the vast scientific advances in almost every aspect of the technology and mathematics, neural networks still need to be fairly large and complex (i.e., deep), in order to provide robust results. In this article, we propose a novel ANN architecture approach that aims to combine two fairly small Neural Networks based on an introduced probability term of correct classification. Additionally, we present a second ANN, used to reclassify the potentially incorrect results by using the most probable error-free results as additional training data with the predicted labels. The proposed method achieves a rapid decrease in the mean square error compared to other large and complex ANN architectures with a similar execution time. Our approach demonstrates increased effectiveness when applied to various databases, related to wine, iris, the Modified National Institute of Standards and Technology (MNIST) database, the Canadian Institute for Advanced Research (Cifar32), and Fashion MNIST classification problems.
Synthesis and characterization of patterned surfaces and catalytically relevant binary nanocrystalline intermetallic compounds

Synthesis and Characterization of Patterned Surfaces and Catalytically Relevant Binary Nanocrystalline Intermetallic Compounds. (December 2007) Robert E. Cable, B.A., Knox College Co-Chairs of Advisory Committee: Dr. Raymond E. Schaak Dr. James D. Batteas As devices and new technologies continue to shrink, nanocrystalline multi-metal compounds are becoming increasingly important for high efficiency and multifunctionality. However, synthetic methods to make desirable nanocrystalline multi-metallics are not yet matured. In response to this deficiency, we have developed several solution-based methods to synthesize nanocrystalline binary alloy and intermetallic compounds. This dissertation describes the processes we have developed, as well as our investigations into the use of lithographically patterned surfaces for template-directed self-assembly of solution dispersible colloids. We used a modified polyol process to synthesize nanocrystalline intermetallics of late transition and main-group metals in the M-Sn, Pt-M’, and Co-Sb systems. These compounds are known to have interesting physical properties and as nanocrystalline materials they may be useful for magnetic, thermoelectric, and catalytic applications. While the polyol method is quite general, it is limited to metals that are somewhat easy to reduce. Accordingly, we focused our synthetic efforts on intermetallics comprised of
Transgenic overexpression of intra-islet ghrelin does not affect insulin secretion or glucose 1 metabolism in vivo 2 Running title : Transgenic overexpression of intra-islet ghrelin 3

16 While ghrelin is primarily produced in the stomach, but a small amount of ghrelin is 17 also produced in pancreatic islets. Although exogenous administration of ghrelin suppresses 18 insulin secretion in vitro or in vivo, the role of intra islet ghrelin in the regulation of insulin 19 secretion in vivo remains unclear. To understand the physiological role of intra-islet ghrelin in 20 insulin secretion and glucose metabolism, we developed a transgenic (Tg) mouse model, rat 21 insulin II promoter ghrelininternal ribosomal entry site –ghrelin O-acyl transferase (RIP-GG) 22 Tg mice, in which mouse ghrelin cDNA and ghrelin O-acyltransferase are overexpressed under 23 the control of the rat insulin II promoter. 24 Although pancreatic desacyl ghrelin levels were elevated in RIP-GG Tg mice, 25 pancreatic ghrelin levels were not altered in animals on standard diet. When Tg mice were fed a 26 medium chain triglyceride rich diet (MCTD), however, pancreatic ghrelin levels were elevated 27 to approximately 16 times that seen in control animals. It seems likely that the gastric ghrelin 28 cells possess specific machinery to provide the octanoyl acid necessary for ghrelin acylation, but 29 that this machinery is absent from pancreatic β cells. Despite the overexpression of ghrelin, 30 plasma ghrelin levels in the portal veins of RIP-GG Tg mice were unchanged from control 31 levels. Glucose tolerance, insulin secretion and islet architecture in RIP-GG Tg mice were not 32 significantly different even when the mice were fed a MCTD. These results indicate that 33 intra-islet ghrelin does not play a major role in the regulation of insulin secretion in vivo. 34
Penerapan Regresi Binomial Negatif Dalam Mengatasi Overdispersi Regresi Poisson Pada Kasus Jumlah Kematian Ibu

Angka kematian ibu merupakan banyaknya kematian yang terjadi selama proses kehamilan serta dalam periode 42 hari setelah berakhirnya kehamilan per 100.000 kelahiran hidup. Hubungan antara faktor-faktor dengan banyaknya kematian ibu dapat diketahui dengan menggunakan analisis regresi Poisson. Penelitian ini menggunakan data tahun 2018 dari Dinas Kesehatan Provinsi Sulawesi Utara berupa jumlah kematian ibu sebagai variabel respon dan sejumlah variabel prediktor dengan unit pengamatannya adalah kabupaten/kota. Dalam analisis regresi Poisson, variabel respon mengasumsikan ekuidispersi (nilai ragam sama dengan nilai rataannya). Namun, dalam data riil seringkali terjadi overdispersi (nilai varians lebih besar dari mean). Salah satu cara untuk mengatasinya adalah dengan analisis regresi binomial negatif. Tujuan dari penelitian ini adalah menentukan model regresi Poisson dan regresi binomial negatif untuk mendapatkan faktor-faktor yang secara signifikan mempengaruhi jumlah kematian ibu di Provinsi Sulawesi Utara. Model regresi binomial negatif yang diperoleh adalah bertambahnya jumlah kasus perdarahan pada ibu hamil dan jumlah kasus yang disebabkan oleh faktor-faktor lainnya , maka akan meningkatkan angka kematian ibu di Provinsi Sulawesi Utara.
Medial Versus Conventional Approach for Prevention of Lateral Cutaneous Nerve Injury in Total hip Arthroplasty with Direct Anterior Approach: A Study for Dual-center, Single-blind, Randomized Controlled Trial

Background; Lateral cutaneous nerve (LFCN) injury is one of the complication specific to total hip arthroplasty via the direct anterior approach. Recent anatomical studies have revealed that the LFCN not only courses between the sartorius and tensor fasciae latae muscles, but it also branches radially while distributing in the transverse direction from the sartorius muscle to the tensor fasciae latae muscle. The latter is called the fan type, in which injury of the LFCN is almost unavoidable using the conventional site for incision of the fascia. In order to reduce LFCN injury in the fan type, we devised a new approach of incising the fascia at a side 2 cm medial from the conventional site of incision. The purpose of this study is to examine how the site of incision of the fascia influences LFCN injury.Methods; This is a prospective, randomized, controlled study. All patients are divided into the fan type and non-fan type using ultrasonography before surgery. Patients with the fan type LFCN will be performed by the conventional approach and the medial approach in the order specified in the allocation table created in advance by our clinical trial center. The conventional approach involves incision of the skin, followed by incision of the fascia just below the site of skin incision. The medial approach proceeds medially from the site of skin incision, and involves incision of the fascia at a site 2 cm medial from the conventional site of incision. The primary endpoint is the presence of LFCN injury. The secondary endpoints will be assessed based on PROs at 3 months after surgery in an outpatient setting using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ), and the Forgotten-Joint Score-12 (FJS-12). Discussion; We hypothesize that the fan type LFCN can be protected from injury by incising the fascia at a more medial site than conventional site. If the usefulness of this surgical procedure is confirmed, the disadvantages of the DAA will be eliminated, potentially being highly beneficial to patients.Trial registration; UMIN Clinical Trials Registry, UMIN000035944.Registered on 20 Feburary 2019.
Understanding Investment Behavior Intention to Adopt Online Mutual Funds Based on Unified Theory of Acceptance and Use of Technology Model

This research build up a calculatede model that consolidates unified theory of acceptance and use of technology (UTAUT), perceived risk and perceived return with age and gender as moderating effect to explain investors behaviour intention and usage behaviour of mutual funds investor in Indonesia. The sample was conducted by stratified random sampling method. Collecting data was conducted by a questionnaire and distributed online using typeform to Indonesian online mutual funds investors as much 396 questionnaires. The statistical used was SPSS, PLS-SEM and PLS-MGA, with hypotheses testing of statistic t-tests and p-value. The consequence of this examination indicatated that the connections of UTAUT, such as performance expectancy, effort expectancy, social influence, and also the role of perceived return as a stronger predictor of investment behavior intention. This UTAUT extention model was then tested using the original data and found to out perform the investment behaviour intention with determinant value of 74 percent and this research also found that the investor behaviour intention didn’t significantly affect the actual investor usage behaviour.
Exploring Effective Classroom Management Constraints in EFL Context: A Phenomenological Inquiry

For years, effective classroom management and the constraints which affect teachers’ classroom management have been of much concern to both teachers and teacher educators. Despite such paramount importance, this issue has been far less explored in general and the Iranian EFL context in particular. Therefore, the current study employed a phenomenological inquiry to delve into the constraints which set hurdles in the way of effective classroom management. To that end, 20 Iranian EFL teachers from different branches of the same English Language Institute were selected through purposive sampling and interviewed in person to extract thick and in-depth data. The interviews then were transcribed verbatim and their content was inductively analyzed to let frequent themes emerge. Results of the analysis indicated that four major themes, namely ‘institute-related’, ‘learner-related’, ‘teacher-related’, and ‘social-cultural differences’ frequently manifested. It should be noted that each main theme also comprised several sub-themes. Some stakeholders such as teachers and teacher educators could benefit from the findings to promote the quality of EFL teachers’ classroom management.
Concept of indecisiveness within the HEXACO personality framework

BACKGROUND Decision making is one of the basic human activities. Indecisiveness, i.e. the stable tendency towards not making decisions in a timely manner, may influence the quality and speed in decision making and have long-term consequences for our professional and personal life. The goal of this research was to examine the position of indecisiveness within the HEXACO model of personality, at both the broad domains and narrow facets level. A secondary goal was to translate the Frost & Shows Indecisiveness Scale (IS) into the Croatian language and examine its validity and reliability. PARTICIPANTS AND PROCEDURE An internet-based sample size of 296 participants filled in both short and long version of Indecisiveness Scale and the HEXACO-PI-R. RESULTS The results show that the IS retains the original one-factor structure as proposed by the original authors and has a high reliability. The shortened version shows properties very similar to the longer version and is deemed an appropriate replacement. Extraversion showed the highest positive correlation with indecisiveness, followed by negative correlations with conscientiousness, emotionality and agreeableness. CONCLUSIONS The Croatian translation of the IS is a valid and reliable measure. The results also confirm that the shortened 11-item version can be used as a replacement for the full 15-item version. Since there was no measure of indecisiveness in Croatian before, this instrument could be used in the future by researchers interested in this construct. It was shown that extraversion has the strongest relationship with indecisiveness, followed by conscientiousness, emotionality and agreeableness.
Collecting Cultural Feedback on Ethiopian Views on Girls, Sport, and Voice

This qualitative study used data collected from five interviews conducted to gather cultural and linguistic feedback on a 21-question instrument created for a future study focused on Ethiopian girl athletes. Participants met the following criteria: (a) native to Ethiopia (b) at least 15 years old and (c) proficient English reading and speaking skills. Participants did not complete the questionnaire, rather, they read it and provided cultural and linguistic feedback on its content. Participants provided feedback via interviews both in person and over the phone during a two-week period. The instrument was designed to collect data from members of Girls Gotta Run Foundation, a non-profit organization in Ethiopia that uses sport to promote gender equity. It consists of questions that focus on girls’ perceptions on the constructs of gender, sport, and voice empowerment. Findings demonstrated the importance of providing greater flexibility in questions that related to age and career goals, while the impact running has on Ethiopian culture was reinforced. Conducting this pilot study demonstrated the importance of testing cross-cultural instruments prior to final instrument administration to gain the most culturally accurate data possible.
Describing the Structure and Relationship of Height and Diameter in an Old Unmanaged Eucalyptus spp. Plantation

The aim of this study was to model the height and diameter distributions and the height-diameter relationship in an old unmanaged Eucalyptus stand in southeastern Brazil. The diameter at 1.30 m above soil (DBH) and total height (H) of all 469 trees in the stand were measured. For the DBH-H modeling, besides testing various traditional linear and nonlinear models, the inclusion of diameter class as random effect was also testes. For the DBH and H distributions modeling, seven probability density function were tested. The DBH-H relationship was best represented by the Henriksen’s linear model. Including diameter classes as a random effect did not improve estimates. The three parameters Weibull distribution was the best model to describe the diameter and height in old and unmanaged planting of Eucalyptus. The DBH distribution showed the highest frequency of individuals in lower diametrical classes, influenced by competition, while H had distribution similar to normal.
THE EFFECT OF INTRAVITREOUS INJECTIONS OF NOREPINEPHRINE, EPINEPHRINE AND ISOPROTERENOL ON THE INTRAOCULAR PRESSURE AND AQUEOUS HUMOR DYNAMICS OF RABBIT EYES

A new technique has been used to study the action of drugs on the intraocular pressure and aqueous humor dynamics. The method involves injection of the drugs directly into the vitreous humor, and observation of their effects following a suitable waiting period by analysis of pressure decay curves. Pressure-infusion studies have also been used to confirm these results. The actions of epinephrine (E), norepinephrine (NE) and isoproterenol (ISO) on the aqueous humor dynamics have been observed using this technique. These studies have shown that NE lowers intraocular pressure primarily by increasing the facility of outflow of aqueous humor. E was found to affect both the facility of outflow and the rate of formation of aqueous humor, and ISO was observed to lower intraocular pressure solely by decreasing the rate of formation of aqueous humor. The results have been discussed in the light of present knowledge concerning the formation and outflow of aqueous humor in the eye.
Empirical Validation of a Biogas Plant Simulation Model and Analysis of Biogas Upgrading Potentials

Biogas plants may support the transformation towards renewable-based and integrated energy systems by providing dispatchable co-generation as well as opportunities for biogas upgrading or power-to-X conversion. In this paper, a simulation model that comprises the main dynamics of the internal processes of a biogas plant is developed. Based on first-order kinetics of the anaerobic digestion process, the biogas production of an input feeding schedule of raw material can be estimated. The output of the plant in terms of electrical and thermal energy is validated against empirical data from a 3-MW biogas plant on the Danish island of Bornholm. The results show that the model provides an accurate representation of the processes within a biogas plant. The paper further provides insights on the functioning of the biogas plant on Bornholm as well as discusses upgrading potentials of biogas to biomethane at the plant from an energy perspective.
Permanent Magnet Synchronous Machine Torque Estimation Using Low Cost Hall-Effect Sensors

Torque measurement/estimation in permanent magnet synchronous machines (PMSMs) is required in a large variety of applications. Direct torque measurement by means of torque transducers is typically limited to laboratory applications due to cost, reliability, and room concerns. Alternatively, torque can be estimated. Torque estimation methods require accurate knowledge of machine parameters. Injection of a high frequency (HF) signal in the stator via inverter has been shown to be a viable option for online machine parameters identification in PMSMs. However, this introduces concerns on the performance of the machine due to the noise, vibration, and additional losses produced by the HF signal. This article proposes a torque estimation method for PMSMs using low cost Hall-effect sensors. The method is based on the dependency of the leakage flux complex vector due to interaction between permanent magnet flux and stator coil flux and does not interfere with the drive operation of the machine.
Synthesis and Characterization of Nanosized Fe2O3 Pigments

The work in this paper was devoted to investigating some nanosized iron oxide pigments prepared by microemulsion technique. The role of concentration of iron salt and surfactant (cetyltrimethylammonium bromide) on the produced iron oxide was studied. The techniques employed to characterize the samples were thermogravimetric analysis, X-ray diffractometry, transmission electron microscope, infrared spectroscopy, and diffuse reflectance spectroscopy. The results revealed that the particle size of the prepared sample using 0.2 M iron sulfate and 3.2 wt% of surfactant was in the range 7–9 nm. Increasing the concentration of either iron salt or the surfactant increased the particle size of the obtained ferric oxide. The diffuse reflectance measurements showed that the charge transfer/electron pair transition absorption peak, which is closely related to the reddish color of the oxide, was shifted to a longer wavelength (blue shift) by decreasing the dimension of the particles. The samples were tested as pigments. They showed different tints of red color and were found to be promising for applications as pigments in the field of paint manufacturing.
Global Conservation Status of Croaker and Drum (Family: Sciaenidae) and Role of the Maw Trade

GLOBAL CONSERVATION STATUS OF CROAKER AND DRUM (FAMILY: SCIAENIDAE) AND THE ROLE OF THE MAW TRADE Claire E. Gorman Old Dominion University, 2020 Director: Dr. Kent E. Carpenter Understanding threats and drivers of extinction risk is critical to conserving marine biodiversity. Although marine bony fishes are some of the most diverse and abundant vertebrates in the world, overexploitation is the major threat to these taxa. Species in the family Sciaenidae are important marine resources in many parts of the world, supporting smalland large-scale fisheries for consumption and the international maw (dried swimbladder) trade. Sciaenids exhibit a diverse array of life history characteristics, such as high fecundity, large body size, formation of spawning aggregations, and longevity. Some characteristics increase their susceptibility to anthropogenic stressors. Despite being ecologically and economically important, data regarding species’ population status and ecology are limited. In this study, I evaluated extinction risk for the 286 valid sciaenid species using the International Union for Conservation of Nature Red List methodology and explored impacts of the maw trade. About 10% of sciaenids overall are of elevated concern (EC). The majority were assessed as Least Concern, but data were insufficient to assign an appropriate Red List category for over 25% of species. Compared to non-maw trade species, those used in the trade have a larger proportion of EC species. Overexploitation was the major threat overall, impacting over 150 species. These results highlight the urgent need for additional research into the maw trade, specifically composition of species, status of Data Deficient species, and price data for maw products. This study completes the first comprehensive analysis of the conservation status of Sciaenidae and provides a foundation for future research
