Authors: Li Shenlong , Pang Ruikun , Liu Jing
Published: October 2022

Planetary gear systems are widely used in wind power, ships, aircraft, and construction machinery, etc. In the planetary gear system, when the eccentricity error exists in the planetary gear, the vibrations of the whole system should be affected. However, the influence of the eccentricity error was rarely considered in the previous dynamic models. To solve this problem, a planetary gear system with six planetary gears is established. The influence of the eccentricity error on the vibrations of the planetary gear system is analyzed. Different eccentricity error cases in the planetary gears are considered in the model, as well as the bearings with the radial clearance. The model with the eccentricity error is compared with the normal model. The statistics of dynamic responses of the ring gear and its variations are analyzed. Not that the vibrations of the planetary gear transmission system increase with the eccentricity error of planetary gear. This study can provide a new method for simulating and detecting the eccentricity errors in the planetary gear systems.

Economic Crisis as a Supervening Event: Legal and Economic Perspectives on Impossibility Doctrine
Authors:   Universitas Prasetiya Mulya, Tangerang Selatan, Harnowo Tri
Published: October 2022

The article attempts to examine the application of the impossibility doctrine toward economic crisis from the legal and economic point of view using the Asian economic crisis case. From a legal perspective, the economic crisis occurs after the conclusion of the contract, unforeseeable at the time of the conclusion of the contract, beyond the control of the promisor, and the risk of the event was not assumed by the promisor may constitute impossibility. From the economic analysis, it is evident that the foreign lenders should bear the risk as they have relatively better ability in predicting the event’s occurrence, are in a better position to diversify risks by pooling a self-insurance, engage in risky investment (mismatch maturity investment) while international environment makes borrowers less likely to hedge their loans. It also found that foreign banks do not expose to the Indonesia economic crisis, are better position to pooling a risk, have multiple cushions from being deprived out of the market. While another justification to apply the impossibility doctrine, in this case, is to avoid bankruptcy cost. It is suggested to use tools of analysis in applying impossibility doctrine: (i) the promisor (borrower) asking to discharged could not reasonably have prevented the event rendering his performance uneconomical, (ii) the promisee (lender) is in a better position to predict the probability of the occurrence of the event occurrence and the magnitude of the loss if it occurred, (iii) the promisee (lender) is in a better position to pooling risk, (iv) the promisor (borrower) does not have its wealth more positively correlated with the event (i.e. depreciation), and (v) he promisor (borrower) does not make a profit out of the market movement as a whole.

The concerning numbers of copyright infringement in Indonesia’s creative industries raises a question on whether there is an obstacle in enforcing the law or whether there are loopholes in its regulatory framework. Comparatively, the United States as one of the developed countries, is rather firm and strict when it comes to protecting its intellectual property rights against other countries. While the ever-growing business sectors may play a significant role in contributing to the strict protection of copyright law for its economic growth, the United States’ legal framework regarding copyright must also play a predominant role in safeguarding its copyright protection. Therefore, the main goal of this article is to analyze the differences between the provisions stipulated in the copyright regulation in Indonesia and the copyright regulation in the United States. In addition, by conducting a comparison with the United States’ legal framework, this article seeks to reflect on what improvements shall be made towards the legal framework in Indonesia, in order to accommodate the protection of creators’ exclusive rights in creative industries more effectively.

Published: October 2022

Humans and the environment are two elements that should coexist. All levels of society should own related awareness of maintaining the environment. However, in reality, the river border community's awareness of the importance of preserving the environment is still lacking. One of the triggering factors is the lack of public legal awareness about the environment. the Green Constitution echoes the regulation of human rights to the environment in the state constitution as a commitment to environmental protection and management. The purpose of this activity is to foster an understanding of the legal awareness of the river coast community about the environment, understanding of regulations or alternative environmental policies on the river coast, and the community's ability as a pioneer of environmental law. The research method used in this study is using a qualitative approach. Data collection techniques by participant observation and focus groups discussion. Data analysis techniques with qualitative descriptive analysis techniques. The expected outcome is that the residents of the riverbank communities will gain advanced knowledge and understanding of legal awareness to protect the environment through the Green Constitutions program.
Secure Data Sharing with Blockchain for Remote Health Monitoring Applications: Systematic Review (Preprint)
Authors: Upadrista Venkatesh , Nazir Sajid , Tianfield Huaglory
Published: October 2022

BACKGROUND

Internet of Medical Things (IoMT) is going to reinvent the future healthcare industry and bring abundant value to hospitals, doctors and patients by overcoming the many challenges currently being faced in monitoring individual’s wellbeing, promoting preventive care, and managing quality of drugs and equipment. Despite the many benefits of RHM, it is yet to be widely adopted and deployed due to the healthcare data security and privacy challenges. The healthcare data is highly sensitive and requires fail-safe measures against unauthorized data access, leaks and manipulations. There are stringent regulations governing how the healthcare data can be secured, communicated and stored such as General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA). These challenges and regulatory demands in the RHM applications can be addressed using blockchain technology due to its distinguishing features of decentralization, immutability and transparency thereby addressing the challenges of security and privacy. This article provides a systematic review of the use of blockchain in RHM focusing on security and privacy.

OBJECTIVE

To systematically review the available literature on Remote Health Monitoring focusing on security and privacy with special focus on Blockchain.

METHODS

A systematic search was conducted across Arxiv, IEEE and Medrxiv to identify literatures across three areas which are remote health monitoring, remote health monitoring focusing on security and privacy and remote health monitoring focusing with blockchain. A total of 6516 references from all the publication hits were screened, 152 papers were retrieved for full text analysis after eliminating duplicates and irrelevant ones, 71 relevant papers are documented as part of this study.

RESULTS

In this survey paper, we conducted a comprehensive review of the blockchain-based RHM systems. It is clear by analyzing these studies that public blockchains still have several limitations, but in comparison private blockchain models can overcome security and privacy concerns. However, the private blockchains have the issue of a single point of failure that needs to be addressed.

CONCLUSIONS

The utilization of blockchain for RHM Use cases has many benefits for the patients’ healthcare professionals, and related stakeholders. However, security and privacy should be addressed to make RHM successful.
Functional Impairment in Individuals Exposed to Violence Based on Electronical Forensic Medical Record Mining and Their Profile Identification: Controlled Observational Study (Preprint)
Authors: Lerner Ivan , Chariot Patrick , Lefèvre Thomas
Published: October 2022

BACKGROUND

Little is known about the functional consequences of violence when directly assessed as a primary outcome, and even less about how consistently these consequences are evaluated in a judicial context. The World Health Organization (WHO) highlighted the importance of a functional approach to health in 2001 with the release of the International Classification of Functioning, Disability, and Health (ICF). In most European countries, forensic physicians assess individuals exposed to violence to evaluate the outcomes of violence, providing certified medical evidence for magistrates’ sentencing decisions. This evaluation involves a mix of objective, subjective, and contextual elements, such as reported symptoms of fear, pain, and details of the assault. Quantifying these subjective elements with scales could enhance their interpretation and application in a judicial context.

OBJECTIVE

This study aims to (1) characterize and (2) assess 6 scales measuring subjective elements of functional impairment among individuals exposed to violence.

METHODS

We conducted a retrospective study that included individuals exposed to violence examined in a French department of forensic medicine over 12 months. A typology of violence encountered in medical settings was built based on the mining of electronic health records and the use of pattern recognition algorithms. The optimal number of violence types was determined using a robust and stable clustering approach, involving sample resampling and a multimetric scheme. Patients were then paired according to their homogeneous profiles, and the intra- and interrater reproducibility of the scales was evaluated.

RESULTS

All pain, fear, and life threat scales were significantly associated with higher functional impairment, suggesting that these measures contribute to the overall assessment of functional impairment. The intra- and interrater reproducibility of scales among similar situations of violence was measured, ranging from mild to good, with coefficients of concordance between 0.46-0.66 and 0.43-0.66, respectively. Individuals reporting intimate partner violence showed higher scores in both fear and perception of a life threat during the assault and medical interview, while individuals reporting battery by multiple unknown assailants presented higher scores only in perception of a life threat during the assault. We identified 5 remarkably stable profiles of situations of violence, consistent with clinical practice.

CONCLUSIONS

Pain, fear, and life threat scales were related to functional impairment according to expert knowledge and demonstrated fair reproducibility under real-life conditions for similar situations of violence. Subjective elements related to functional impairment in individuals exposed to violence can be quantified using Likert scales during medical interviews.
Large language models for epidemiological research via automated machine learning: a case study and method comparison from the British National Child Development Study (Preprint)
Authors: Wibaek Rasmus , Andersen Gregers Stig , Dahm Christina C , Witte Daniel R , Hulman Adam
Published: October 2022

BACKGROUND

Large language models have had a huge impact on natural language processing (NLP) in recent years. However, their application in epidemiological research is still limited to analysis of electronic health records and social media data.

OBJECTIVE

To demonstrate the potential of NLP beyond these domains, we aimed to develop prediction models based on texts collected in an epidemiological cohort and compared their performance to classical regression methods.

METHODS

We used data from the British National Child Development Study, where 10,567 11-year-old children wrote essays about how they imagined themselves as 25-year-olds. Fifteen percent of the dataset was set aside as a test set for performance evaluation. Pre-trained language models were fine-tuned using AutoTrain (by Hugging Face) to predict current reading comprehension score (0-35) and future body mass index (BMI) and physical activity (active vs. inactive) at the age of 33. We then compared their predictive performance (accuracy or discrimination) with linear and logistic regression models including demographic and lifestyle factors of the parents and the children between birth and age 11 as predictors.

RESULTS

NLP clearly outperformed linear regression when predicting reading comprehension score (RMSE=3.89 [95% CI: 3.74, 4.05] for NLP vs. 4.14 [3.98, 4.30] and 5.41 [5.23, 5.58] for regression models with and without general ability score as predictor). Predictive performance for physical activity was similarly poor for the two methods (AUC ROC=0.55 [0.52, 0.60] for both), but slightly better than random assignment, while linear regression clearly outperformed the NLP approach when predicting BMI (RMSE=4.38 [4.02, 4.74] for NLP vs. 3.85 [3.54, 4.16] for regression). The NLP approach did not perform better than simply assigning the mean BMI from the training set as predictors.

CONCLUSIONS

Our study demonstrated the potential of using large language models to utilize text collected in epidemiological studies. The performance of the approach appeared to depend on how directly the topic of the text was related to outcome. Open-ended questions specifically designed to capture certain health concepts and lived experiences in combination with NLP methods should receive more attention in future epidemiological studies.

Production, Purification and Characterization of Extracellular Tannase from a Newly Isolated Yeast, Geotrichum cucujoidarum
Authors: Thangavelu Nishanthini , Hugar Priyanka , Belur Prasanna D.
Published: October 2022

With an aim to isolate a tannase positive organism, the microbial mat growing on the stored areca extract leachate surface was screened. Once the tannase positive organism was isolated, it was identified by ITS/18S rRNA gene sequencing. Further, the enzyme was purified and examined for its biochemical properties. A potent extracellular tannase-producing yeast was isolated and was identified as Geotrichum cucujoidarum. After the shake flask studies, the enzyme activity of 4.42 U/ml and specific activity of 29.86 U/mg were achieved in a medium with tannic acid as an inducer. Later, ethanol (70%) precipitation followed by purification through FPLC using SEC 650 column resulted in 166.37 U/mg specific activity and a recovery of 50.54%. The purified enzyme was a monomer with a molecular weight of 63 kDa. The optimum pH and the temperature of the enzyme were found to be 5.0 and 30°C, respectively. The Michaelis-Menten constant (Km) was found to be 2.9 mM, and the turn over number (kcat) and catalytic efficiency (kcat/km) of the purified tannase were 102 S-1 and 35.17 mM-1S-1 respectively. Temperature and pH stability profiles of the enzyme, influence of various metal ions, chelators and surfactants on enzyme activity and kinetic constants of enzyme shows that the tannase produced from Geotrichum cucujoidarum is unique and is a potential candidate for further studies.
The influence of direct measurement weights over the statistical quality of solving inverse photogrammetry tasks
Authors: Voronin E.G.
Published: October 2022

The article is the second in a series of publications dealing with studying various aspects of statistical quality at solving inverse photogrammetry matters. The author examines the influence of direct measurement weights over the results of the equalization. It is noted that significant errors in evaluating weights of direct measurements of equalized parameters’ residuals can lead not only to the transformation of projecting beams’ bundles, but also to the phototriangulation unit’s deformation. A graphic illustration of this phenomenon is given by the example of a real route of optical-electronic space survey. The concepts of statistical quality of equalization for direct and indirect measurements are introduced. Analytical expressions are proposed for estimating this quality. The differences between the residuals fixed terminologically in their names are shown. The criteria of equalizing the above mentioned measurements’ statistical quality are obtained. The advantages and disadvantages of the weighting method of least squares in comparison with its generalized version in determining the weights of direct measurements of correlated equalized parameters are noted. An algorithm for correcting them was developed to improve the statistical quality of their equalizing. Experimental calculations were performed based on real satellite images obtained with the panchromatic equipment of the Resurs-DK spacecraft, which confirmed the effectivity of the proposed algorithm.

Published: October 2022

Background: Hyperbaric oxygenation (HBO2) involves breathing 100% oxygen under elevated ambient pressure in a hyperbaric chamber, thereby dissolving oxygen in the plasma. This results in an increase of arterial partial pressure of oxygen (pO2). Though well established in experimental studies, HBO2 treatment for ischemic stroke is still under discussion. Methods: From 2002-2014 HBO2 (2.2 bar, 90 minutes one/day; average number per patient: 4.7) was applied in 49 consecutive patients (32 males, 17 females, mean age: 68.8 years, range 31.2 – 83.9) with acute neurological deficit following cardiac surgery (CABG 15; combined surgery 14; valve surgery 11; aneurysm repair 8; malformation 1). Patients’ history including TIA or stroke and carotid artery pathology were documented. Both degree and type of neurological deficit was evaluated by a scoring system (0-4) before and after HBO2 treatment. Results: Before HBO2 therapy, the average motor deficit score was 2.45 and the average speech disorder score was 0.55, as compared with an average motor deficit of 1.12 and an average speech disorder of 0.27 afterward (α=0.0001, α=0.009). The majority of patients had an overall improvement of 2 score-points after HBO2 therapy (n=23 patients). Probit analysis showed that for a 50% response/probability (LC50) of having an overall outcome of ≥2 scoring points, an estimate of 4.3 HBO2 therapy sessions is necessary. Conclusion: HBO2 therapy was associated with significant improvement in patients with acute neurological deficits due to ischemic stroke following cardiac surgery. Though this fact suggests gas embolism as the most likely cause of stroke in this collective, other underlying pathologies cannot be ruled out. Randomized studies are needed for further evaluation.

Published: October 2022

Artisanal fishermen around the world employ scuba and surface- supplied diving for their livelihoods and often undergo provocative dive profiles due to economic pressures. Consequently, rates of decompression sickness (DCS) are much greater than in recreational scuba divers. Here we present the case of a surface-supplied diving fisherman from the Yucatán Peninsula of Mexico who suffered a significant episode of spinal DCS and underwent hyperbaric oxygen therapy treatments, with a favorable outcome. Additionally, we review the proposed mechanisms underlying spinal DCS.

Published: October 2022

Background and purpose: Proximal tibial fractures are infrequent injuries in children, and the literature on epidemiology, associated injuries, and management is limited. We calculated a population-based incidence and described the characteristics of proximal tibial fractures in children in terms of complications and management.Patients and methods: This is a retrospective study over a 6-year-period during including 241 children with proximal tibial fractures who presented to our university hospital. Demographic and fracture-related data was collected from the Kids’ Fracture Tool. The number of children during the study period was collected from statistical yearbooks of the City of Helsinki to estimate annual incidence.Results: Extra-articular fractures (129/241) peaked at the age of 3 and tibial tubercle (42/241) and intra-articular fractures (70/241) peaked at the age of 15. Annual incidences were estimated to be 3.4/100,000 children and 22/100,000 children in the age group of 13–16 years for ACL avulsions, and 3.8/100,000 children and 21/100,000 children in the age group of 13–16 years for tibial tubercle fractures. The incidence of vascular compromise (0%) and compartment syndrome was low (0.4 %, 1/241).Conclusion: Proximal tibial fractures present with a bimodal distribution, with extra-articular fractures peaking at the age of 3 years and fractures of the tibial tuberosity and intra-articular fractures peaking at the age of 15 years. Additionally, associated compartment syndrome and vascular compromise was not as common as previously reported.
The Effect of Pin Shape on the Friction Stir Welding Quality of Aluminum AA1100 Series
Authors: Sukmana Irza
Published: October 2022

Aluminum is a material that is soft, lightweight, resistant to corrosion, and has good electrical and thermal conductivity. Aluminum has a specific gravity of about 2.65-2.8 kg/dm³, a melting point of 658ºC, and tensile strength of 90 MPa. Aluminum 1100 series is an aluminum alloy mixed with other materials, such as copper, iron, chrome, manganese, and zinc, with an aluminum content of 99,0%. Welding is the joining of two metals in a liquid state with or without filler. FSW (friction stir welding) is friction welding; the process does not require filler material. The heat used to melt the metal is obtained from the friction between the indenter and the workpiece. In the research, the shape of the indenter pin used is, ovale shape, cone shape, and changing spiral form with a tool rotation of 2000 rpm and a welding rate of 16 mm/minute. The tests carried out are Rockwell hardness testing and tensile tests. From the results of research conducted, it was found that the shape of the indenter pin greatly affects the quality of the weld. The indenter pin changing spiral form results in better weld quality compared to the other two pin shapes.
Influence of Rice Establishment Methods on Water Productivity, Methane Emissions and Rice Grain Heavy Metals Content from Irrigated Rice Paddies in Bangladesh

Published: October 2022

Reducing methane (CH4) emissions and water use in irrigated rice systems while maintaining production to feed the ever-increasing population is vital in Bangladesh. Different rice establishment methods viz. alternate wetting & drying (AWD), system rice intensification (SRI) and direct wet seeded rice (DWSR), have a promising mitigation potential to reduce CH4emission compared to continuous flooded (CF) rice fields. A field experiment was conducted at Bangladesh Agricultural University, Mymensingh, during the Boro season in 2018 to examine whether rice establishment methods could maintain grain yield with reduced water use and CH4emissions. A split-plot design was employed with water management in the main plots and fertilizer management in the subplots. The yield difference was not significant (p>0.05) in CF, AWD, and SRI systems other than DWSR. Planting methods in combination with organic fertilizer amendment had little effect on the grain Fe, Zn, and Cd concentration but significantly affected the as concentration. AWD, SRI, and DWSR significantly reduced the total water use by 17-33% and increased water productivity by 22-35% compared to CF. SRI system performed superior (p>0.05) by increasing the water productivity coupled with reducing water consumption compared to CF. The impact of water management on changing climate in rice fields was compared using seasonal CH4emission and yield-scaled global warming potential (GWP). Total seasonal CH4emissions were significantly distinct (p<0.05) from different rice establishment methods. Seasonal CH4 emissions from CF, AWD, SRI, and DWSR systems were 147.85, 128.11, 110.35, and 91.52kg CH4 ha-1, respectively. Emissions were reduced by about 13-38% in contrast with continuous flooded soil. The emissions of greenhouse gases per unit grain yield (yield-scaled GWP) followed the order; CF>AWD>DWSR>SRI, while reducing yield-scaled emissions from AWD, SRI and DWSR decreased around 15-25% over that of the CF system. In conclusion, it is recommended that both SRI and AWD can mitigate CH4 emission, powered reduce water consumption as well as grain content from irrigated rice fields without yield penalty.

The Sindang Barang Cultural Village was formed by the descendants of customary holders who live in Bogor to revitalize Sundanese culture. This is useful for preserving customs so that people can continue to live the Sundanese way (using indigenous knowledge and sticking to local wisdom) even though they live in the modern era. This study aims to identify the Sundanese indigenous knowledge possessed by them. This study uses a qualitative thematic analysis approach to identify it. The results of this study indicate that the themes of indigenous knowledge owned by the society are village landscape, agriculture, natural signs, health, and batik. The village landscape has sub-themes landscape of land and building position. The sub-themes of agriculture are the type of paddy, fertilizer, planting time, magic guard, and granary. Natural signs have the sub-themes of changing days and signs of calamity and disaster. The sub-theme of health is herbs. Batik has a sub-theme of motifs and natural dyes. This study found that some of the indigenous knowledge about herbs and batik had been lost from the people's memory.

Relativistic Effects in the Rotation of Dwarf Planets and Asteroids
Authors: Pashkevich Vladimir V. , Vershkov Andrey N.
Published: October 2022

The effect of the geodetic rotation (which includes two relativistic effects: geodetic precession and geodetic nutation) is the most significant relativistic effect in the rotation of the celestial bodies. For the first time in this research, this relativistic effect is determined in the rotation of dwarf planets (Ceres, Pluto, and Charon) and asteroids (Pallas, Vesta, Lutetia, Europa, Ida, Eros, Davida, Gaspra, Steins, and Itokawa) in the Solar System with known values of their rotation parameters. Calculations of the values of their geodetic rotation are made by a method for studying any bodies in the Solar System with a long-term ephemeris. Values of geodetic precession and geodetic nutation for all these celestial bodies were calculated in ecliptic Euler angles relative to their proper coordinate systems and in their rotational elements relative to the fixed equator of the Earth and the vernal equinox (at the epoch J2000.0). The obtained analytical values of the geodetic rotation for the celestial bodies can be used to numerically investigate their rotation in the relativistic approximation, and also used to estimate the influence of relativistic effects on the orbital–rotational dynamics for the bodies of exoplanetary systems.

In this study, alkaline-H2O2 sludge disintegration was combined with anoxic-aerobic sequencing batch reactor (SBR). The carbon obtained by alkaline-H2O2 sludge disintegration was used in the denitrification process and sludge reduction was achieved in the SBR process. In the SBR process, a 9 % increase in nitrogen removal efficiency was achieved with the improvement in the denitrification process. A sludge reduction efficiency of 43 % was obtained in the SBR process with alkaline-H2O2 sludge disintegration. A synergistic effect was obtained in the combination of alkaline and H2O2 methods and the sludge reduction increased by 8 %. By combining sludge disintegration into the SBR process, it is possible to reduce the amount of sludge formed, which is an important environmental problem, and to provide carbon source for the denitrification process.
What Do Polygraphers–Practitioners Expect from Science?
Authors: Widacki Jan
Published: October 2022

The purpose of the study was to learn the opinions of polygraph examiners concerning the role and applicability of scientific research in detection of deception conducted in Universities or other scientific centres. The questionnare was distributed among participants of the 56th Annual Seminar of the American Polygraph Association (Orlando Fl. 2022). The 55 copies of the questionnare were hande out, 48 completed sheets were returned. As it could been expected, polygraph examiners are generally not interested in of detection of deception other than the ones they currently using in their practice. The new methods of detection of deception, as for example exploiting the neurophysiological level (EEG, fMRI) or methods remotely observable and registrable indicators other than those that have as yet been used in polygraph examination generally was not interested for him.

The study focuses on the validation of the leaf unfolding (LU) onset of oak stands in the Western Carpathians in 2000–2021 derived from MODIS satellite data. LU onset was derived from the annual trajectories of the Normalised difference vegetation index (NDVI) fitted with a double sigmoid logistic function. The satellite metric Growing speed day (GSD) corresponding to the LU onset is represented by the first derivative of the sigmoid function. Ground-based observations from 22 phenological stations of the Slovak Hydrometeorological Institute (SHMI) were used to validate the date of GSD. The results showed a good agreement between the medians of ground- and satellite-based LU onset dates. In addition to the median, the LU onset at the 5th and 95th percentiles were compared. For both percentiles, we found differences in the onset from MODIS and SHMI. The 5th percentile of the LU onset derived from MODIS was determined later than the one from SHMI data. With the 95th percentile, it was the opposite. As a result, the range determining the duration of LU onset from MODIS was significantly shorter than from SHMI observations. The trend analyses over the period 2000–2021 revealed a shift to the earlier onset of LU ~ 0.33 day.year−1 (p = 0.13) from satellite and ~ 0.32 day.year−1 from ground-based observations (p = 0.08). The validated LU onset and trends using the median allow analysing of the oak stands response to changing environmental conditions. However, the differences at the 5th and 95th percentiles, i.e. at the beginning and the end of the LU onset duration, remained unexplained.
Syntactic variation and interactional coherence in online communication: The German conjunction “weil” in written interactions
Authors: Glaznieks Aivars
Published: October 2022

The current study presents an analysis of a linguistic device supporting interactional coherence in computer-mediated communication (CMC). The analysis focused on the use of the German causative conjunction weil and, more specifically, on the syntactic variation of verb-final versus verb-second word order in the weil-clause. Verb-final word order in German indicates a dependent clause, whereas verb-second word order indicates an independent clause. While only the former is accepted in written Standard German, the latter is well documented in oral communication. Relying on freely available Facebook, WhatsApp, and Wikipedia corpus data, the analysis shows that both grammatical constructions are used in written CMC. In a specific usage across discrete messages, the syntactic variation of the weil-clause can serve to unambiguously identify its reference clause. While verb-final weil-clauses can be used to refer to previous messages by both an interlocutor and oneself, verb-second weil-clauses are predominantly used to relate to an own previous message. Thus, the syntactic variation in weil-clauses can be used for disambiguating references in written interactions.
Referring to other participants in asynchronous online discussions: Citation patterns in a higher education context

Published: October 2022

The effectiveness of asynchronous online discussions as a learning tool in higher education critically depends on the participants’ ability to create a cohesive social space. Referring to one another’s messages is a key way to display a sense of affiliation and solidarity, and contribute to the consolidation of the learning community. However, research has shown that students often fail to adequately exploit this dimension of the online forum, as it requires considerable involvement in the activity and is very time-consuming.In the current study, we examined references to previous posts in a set of online discussions held during a one-term undergraduate course. The overall frequency of citations was low, with slightly over half of the 885 analyzed posts containing at least one reference. While this seems to indicate that a large number of participants conceived the activity as hardly interactive, for those who did quote their classmates, the preferred practice was using their first names, although the more formal name+surname pattern increased in the second half of the course, possibly indicating an awareness of the academic character of the activity. If the frequency and kind of mutual references can be taken as a measure of how successful asynchronous online discussions can prove as a collaborative learning tool, our results invite deep reflection regarding task design to ensure that students and instructors understand their goals in the same way.
