Towards Understanding Online Question & Answer Interactions and their effects on student performance in large-scale STEM classes
Authors: Smith IV David H , Hao Qiang , Dennen Vanessa , Tsikerdekis Michail , Barnes Bradly , Martin Lilu , Tresham Nathan
Published: June 2020

Online question & answer (Q & A) is a distinctive type of online interaction that is impactful on student learning. Prior studies on online interaction in large-scale classes mainly focused on online discussion and were conducted mainly in non-STEM fields. This research aims to quantify the effects of online Q & A interactions on student performance in the context of STEM education. 218 computer science students from a large university in the southeastern United States participated in this research. Data of four online Q & A activities was mined from the online Q & A forum for the course, including three student activities (asking questions, answering questions and viewing questions/answers) and one instructor activity (answering questions/providing clarifications). These activities were found to have different effects on student performance. Viewing questions/answers was found to have the greatest effect, while interaction with instructors showed minimum effects. This research fills the gap of lacking research in online Q & A, and the results of this research can inform the effective usage of online Q & A in large-scale STEM courses.
Estimation and geologic interpretation of regolith chargeability and superparamagnetic susceptibility in airborne electromagnetic data
Authors: Macnae James , Munday Tim , Soerensen Camilla
Published: June 2020

All available inversion software for airborne electromagnetic (AEM) data can at a minimum fit a nondispersive conductivity model to the observed inductive secondary field responses, whether operating in the time or frequency domain. Quasistatic inductive responses are essentially controlled by the induction number, the product of frequency with conductivity and magnetic permeability. Recent research has permitted the conductivity model to be dispersive, commonly using a single Cole-Cole parameterization of the induced polarization (IP) effect; but this parameterization slows down and destabilizes any inversion, and it does not account for the need for dual or multiple Cole-Cole responses. Little has been published on inverting AEM data affected by frequency-dependent magnetic permeability, or superparamagnetism (SPM), usually characterized by a Chikazumi model. Because the IP and SPM effects are small and are usually only obvious at late delay times, the aim of our research is to determine if these IP and SPM effects can be fitted and stripped from the AEM data after being approximated with simple dispersive models. We are able to successfully automate a thin-sheet model to do this stripping. Stripped data then can be inverted using a nondispersive conductivity model. The IP and SPM parameters fitted independently to each independent measured decay to provide stripping are proven to be spatially coherent, and they are geologically sensible. The results are found to enhance interpretation of the regolith geology, particularly the nature and distribution of transported materials that are not afforded by mapping conductivity/conductance alone.
Novel strategies for complex foothills seismic imaging — Part 1: Mega-near-surface velocity estimation
Authors: Li Yalin , Zhu Xianhuai , Peng Gengxin , Liu Liansheng , Duan Wensheng
Published: June 2020

Seismic imaging in foothills areas is challenging because of the complexity of the near-surface and subsurface structures. Single seismic surveys often are not adequate in a foothill-exploration area, and multiple phases with different acquisition designs within the same block are required over time to get desired sampling in space and azimuths for optimizing noise attenuation, velocity estimation, and migration. This is partly because of economic concerns, and it is partly because technology is progressing over time, creating the need for unified criteria in processing workflows and parameters at different blocks in a study area. Each block is defined as a function of not only location but also the acquisition and processing phase. An innovative idea for complex foothills seismic imaging is presented to solve a matrix of blocks and tasks. For each task, such as near-surface velocity estimation and static corrections, signal processing, prestack time migration, velocity-model building, and prestack depth migration, one or two best service companies are selected to work on all blocks. We have implemented streamlined processing efficiently so that Task-1 to Task-n progressed with good coordination. Application of this innovative approach to a mega-project containing 16 3D surveys covering more than [Formula: see text] in the Kelasu foothills, northwestern China, has demonstrated that this innovative approach is a current best practice in complex foothills imaging. To date, this is the largest foothills imaging project in the world. The case study in Kelasu successfully has delivered near-surface velocity models using first arrivals picked up to 3500 m offset for static corrections and 9000 m offset for prestack depth migration from topography. Most importantly, the present megaproject is a merge of several 3D surveys, with the merge performed in a coordinated, systematic fashion in contrast to most land megaprojects. The benefits of this approach and the strategies used in processing data from the various subsurveys are significant. The main achievement from the case study is that the depth images, after the application of the near-surface velocity model estimated from the megasurveys, are more continuous and geologically plausible, leading to more accurate seismic interpretation.

Qualitative Assessment of Unmet Information Management Needs of Informal Cancer Caregivers: Four Themes to Inform Oncology Practice
Authors: Crotty Bradley H. , Asan Onur , Holt Jeana , Tyszka Jeanne , Erickson Jeanne , Stolley Melinda , Pezzin Liliana E. , Nattinger Ann B.
Published: June 2020

PURPOSE

Family and friends often provide informal care for patients with cancer, coordinating care and supporting patients at home. Stress, depression, and burnout are increasingly recognized among these informal caregivers. Although past research has described a range of needs, including the need for information, details about unmet informational needs for caregivers have not been fully described. We sought to assess unmet information management needs for informal caregivers in the digital era.

METHODS

This was a qualitative research study with semistructured interviews and focus groups of nonprofessional caregivers for patients with cancer, facilitated using a discussion guide. Eligible caregivers supported patients in the community who were in treatment (chemotherapy or radiotherapy) or completed treatment within 3 years. Participants were recruited using informational flyers at an academic cancer center and in the local community of metropolitan Milwaukee, Wisconsin. Sessions were transcribed verbatim and analyzed inductively to identify themes.

RESULTS

Thirteen caregivers participated, the majority between 41 and 60 years of age: seven of 13, 53.8%, were predominantly women; 10 of 13 (76.9%) were educated, 10 of 13 (76.9%) had graduated from college; and of modest means, six of 13 (46.2%) had household incomes < $35,000. Four themes emerged: (1) the information overload paradox, where caregivers felt overloaded by information yet had unmet informational needs; (2) navigating volatility as a caregiver, with changing or unknown expectations; (3) caregivers as information brokers, which placed new burdens on caregivers to seek, share, and protect information; and (4) care for the caregiver, including unmet information needs related to self-care.

CONCLUSION

This study identified several informational challenges affecting caregivers. Caregivers have dynamic and evolving informational needs, and strategies that support caregivers through just-in-time information availability or dedicated caregiver check-ins may provide relief within the stress of caregiving.
Tetra-Branched Tetra-Cationic Ionic Liquids: Effects of Spacer and Tail Structure on Physical Properties
Authors: Ikeda Taichi
Published: June 2020

Herein, the synthesis of ten tetra-branched tetra-cationic ionic liquids, which consist of a pentaerythritol-based core, alkylene or ethylenedioxy spacers, imidazolium cationic units, and short alkyl tails, is described. The physical properties of the tetra-cations, including their glass transition and thermal decomposition temperatures, densities, viscosities, and ionic conductivities, were investigated. The tetra-cations were analyzed to determine the effects of the spacer and tail structure on the above-mentioned physical properties. The spacer unit located between the pentaerythrityl core and cationic unit was confirmed to be the key for improving ionic conductivity. A maximum ionic conductivity of 2.8 × 10−4 S cm−1 (25 °C under anhydrous conditions) and a minimum viscosity of 1.6 Pa s (25 °C) were observed. While the physical values of the tetra-cationic ionic liquids are close to those of di-cationic ionic liquids, their structure-property relationship is similar to that of poly-cations rather than di-cations.
CT-guided radiofrequency ablation of osteoid osteoma: established concepts and new ideas
Authors: Singh Dharmendra Kumar , Katyan Amit , Kumar Nishith , Nigam Kanchan , Jaiswal Binita , Misra Ritu Nair
Published: June 2020

Osteoid osteoma is a painful benign bone tumour of children and young adults with characteristic clinico-radiological features depending upon the location of the lesion. Intraoperative visualisation of the nidus is difficult and therefore curative surgery is often associated with excessive bone removal, significant perioperative morbidity and potential need of bone grafting procedures. With advancement in cross-sectional imaging and radiofrequency ablation (RFA) technology, CT-guided RFA has emerged as the treatment of choice for the osteoid osteoma. This procedure involves accurate cannulation of the nidus and subsequent thermocoagulation-induced necrosis.

Multidisciplinary management approach is the standard of care for patients with osteoid osteoma. Appropriate patient selection, identification of imaging pitfalls, pre-anaesthetic evaluation and a protocol-based interventional approach are the cornerstone for a favourable outcome. Comprehensive patient preparation with proper patient position and insulation is important to prevent complications. Use of spinal needle-guided placement of introducer needle, namely, “rail–road technique” is associated with fewer needle trajectory modifications, reduced radiation dose and patient morbidity and less intervention time. Certain other procedural modifications are employed in special situations, for example, intra-articular osteoid osteoma and osteoid osteoma of the subcutaneous bone in order to reduce complications. Treatment follow-up generally includes radiographic assessment and evaluation of pain score. Dynamic contrast-enhanced MRI has been recently found useful for demonstrating post-RFA healing.

Published: June 2020

Regarding the theme of the United Nations Sustainable Development Goals, we decided to concern ourselves with the 3rd goal, “Good Health and Well-Being”, the 12th goal, “Responsible Consumption and Production” and the 17th goal, “Partnerships to achieve the Goal”. Concerning our action involving obesity, we have conducted very detailed research. We realized that obesity and child obesity are both huge problems since the rates around the world nowadays are very high. In an attempt to understand the reasons behind this, we designed a questionnaire, so we could test how healthy our classmates’ lifestyle is. Then we contacted a nutritionist and they helped us make an informational leaflet about obesity, which we distributed to others. Lastly, we designed an online game concerning eating habits. While we did our research, we found out that our daily eating choices impact the environment greatly. Thus, changing our eating habits for the better may prove to be the most effective way to help the environment.
Historicising “containment and delay”: COVID-19, the NHS and high-risk patients
Authors: Moore Martin D.
Published: June 2020

Despite the first case of the novel coronavirus only being reported to the WHO at the end of December 2019, humanities and social science scholars have been quick to subject local, national and international responses to COVID-19 to critique. Through television and radio, blogs, social media and other outlets, historians in particular have situated the ongoing outbreak in relation to previous epidemics and historicised cultural and political responses. This paper furthers these historical considerations of the current pandemic by examining the way the National Health Service (NHS) and discourses of risk have figured in public and policy responses. It suggests that appeals to protect the NHS are based on longer-term anxieties about the service’s capacity to care and endure in the face of growing demand, as well as building on the attachment that has developed as a result of this persistence in the face of existential threats. Similarly, the position of elderly, vulnerable and “at risk” patients relates to complex histories in which their place in social and medical hierarchies have been ambiguous. It thus argues that the ways in which time appears as both a threat and a possibility of management in the current crisis form part of a longer trajectory of political and cultural thinking.
A Branch-and-Price Algorithm for Facility Location with General Facility Cost Functions
Authors: Ni Wenjun , Shu Jia , Song Miao , Xu Dachuan , Zhang Kaike
Published: June 2020

Most existing facility location models assume that the facility cost is either a fixed setup cost or made up of a fixed setup and a problem-specific concave or submodular cost term. This structural property plays a critical role in developing fast branch-and-price, Lagrangian relaxation, constant ratio approximation, and conic integer programming reformulation approaches for these NP-hard problems. Many practical considerations and complicating factors, however, can make the facility cost no longer concave or submodular. By removing this restrictive assumption, we study a new location model that considers general nonlinear costs to operate facilities in the facility location framework. The general model does not even admit any approximation algorithms unless P = NP because it takes the unsplittable hard-capacitated metric facility location problem as a special case. We first reformulate this general model as a set-partitioning model and then propose a branch-and-price approach. Although the corresponding pricing problem is NP-hard, we effectively analyze its structural properties and design an algorithm to solve it efficiently. The numerical results obtained from two implementation examples of the general model demonstrate the effectiveness of the solution approach, reveal the managerial implications, and validate the importance to study the general framework.
Polyhedral Results and Branch-and-Cut for the Resource Loading Problem
Authors: Song Guopeng , Kis Tamás , Leus Roel
Published: June 2020

We study the resource loading problem, which arises in tactical capacity planning. In this problem, one has to plan the intensity of execution of a set of orders to minimize a cost function that penalizes the resource use above given capacity limits and the completion of the orders after their due dates. Our main contributions include a novel mixed-integer linear-programming (MIP)‐based formulation, the investigation of the polyhedra associated with the feasible intensity assignments of individual orders, and a comparison of our branch-and-cut algorithm based on the novel formulation and the related polyhedral results with other MIP formulations. The computational results demonstrate the superiority of our approach. In our formulation and in one of the proofs, we use fundamental results of Egon Balas on disjunctive programming.
Hiding Sensitive Information when Sharing Distributed Transactional Data
Authors: Ghoshal Abhijeet , Hao Jing , Menon Syam , Sarkar Sumit
Published: June 2020

Although retailers recognize the potential value of sharing transactional data with supply chain partners, many remain reluctant to share. However, there is evidence that the extent of sharing would be greater if information sensitive to retailers can be concealed before sharing. Extant research has only considered sensitive information at the organizational level. This is rarely the case in reality; the retail industry has adapted their offerings to region-wide differences in customer tastes for decades. Differences in customer characteristics across regions lead to region-specific sensitive information in addition to any at the organizational level. This is the first paper to propose an approach to solve this version of the problem. Region-level requirements increase the size of an already difficult (NP-hard) problem substantially, making adaptations of existing approaches impractical. We present an ensemble approach that draws intuition from Lagrangian relaxation to conceal sensitive patterns at the organizational and regional levels with minimal damage to the data set. Extensive computational experiments show that it identifies optimal or near-optimal solutions even when other approaches fail, doing so without any loss in recommendation effectiveness. This mitigates potential risks associated with sharing and should increase data sharing among partners in the supply chain.

Trajetórias religiosas de jovens sem religião – algumas implicações para o debate sobre desinstitucionalização
Authors: Fernandes Sílvia
Published: June 2020

Nas últimas duas décadas têm crescido o número de pessoas que se declaram sem religião. Quando são analisados os diversos segmentos sociais a partir de bases censitárias, é entre a juventude que se encontram os maiores índices dos que assumem essa autoidentidade. O fenômeno da desinstitucionalização religiosa passou a ser mais estudado a partir do penúltimo censo brasileiro realizado em 2000, que totalizou 7,4% da população brasileira declarando-se sem religião, o que representou um crescimento de aproximadamente 3% em uma década. Em 2010, os sem religião na população brasileira passaram a ser 8%, mas entre os jovens com idade entre 15 a 29 anos esse número chega a 10,1%. Este artigo objetiva compreender a trajetória de três jovens brasileiros sem religião, ex evangélicos residentes em regiões periféricas do Estado do Rio de Janeiro, onde predominam as igrejas evangélicas de corte pentecostal e neopentecostal. Discute-se o processo de construção da identidade juvenil cuja dinâmica rejeita a religião institucionalizada, e analisam-se as percepções desses jovens sobre tal processo.Palavras-chave:  Juventude sem religião.

Condition of Rumen Fermentation as Impacted by Supplementation of Fermented Rice Brand Using In Vitro Gas Production Technique
Authors: Zuratih Zuratih , Budhi SPS , Bachruddin Z
Published: June 2020

Methane is one of the gases produced by ruminants during feed fermentation in the rumen. This experiment was aimed to investigate the production of monacolin K in rice bran fermented by Monascus purpureus mold and the influence of the supplementation of fermented rice bran using Monascus purpureus mold on elephant grass basal diet on fermentation products and methane production in an in vitro gas production method. The study consisted of two experiments. The first experiment analysis of monacolin K production in fermented rice bran using Monascus purpureus. Fermentation is done by the addition of Monascus purpureus at levels 0, 4, 8, and 12% (v/w) of substrate (rice bran) with 3 replications. Monacolin K in the substrate was analyzed using HPLC. The second experiment was the evaluation of supplementation of fermented rice bran to elephant grass basal diet using in vitro gas production. The treatment diet evaluated were Pennisetum purpureum (control), Pennisetum purpureum:rice bran (1:1 ratio), and Pennisetum purpureum:rice bran fermented. Each treatment was replicated 3 times. Results from the first experiment shows that rice bran with the highest monacolin K content was in rice bran fermented at 12% by Monascus purpureus. Result from the second experiment showed that supplementation of fermented rice bran to Pennisetum purpureum basal diet did not affect rumen ammonia concentration, VFA, protein microbial production, and dry matter and organic matter digestibility. However, methane production (CH4) was reduced (P<0.05) by 50%, and the protozoal population was decreased (P<0.05) by 80%. It is concluded that supplementation of fermented rice brands containing monacolin K was able to reduce methane production and the protozoa population without affecting feed fermentation.
La Virgen sin cabeza. Vida, lenguaje, territorio
Authors: Rodríguez Fermín

La vida es la materia inestable de una serie de novelas latinoamericanas del siglo veintiuno que en medio de la crisis ensayaron con nuevos dispositivos espacio–temporales para desmontar las operaciones biopolíticas fundamentales y, en nombre de lo común, sus amalgamas y prácticas aglutinantes, construir otros ordenamientos de cuerpos y sentidos. «Aventura de la materia» —dice la narradora— fuertemente anclada en la materialidad de los cuerpos, La Virgen Cabeza (2009) de Gabriela Cabezón Cámara se interna entre los escombros de la violencia económica y el abandono político para hacer ver a la luz de los nuevos regímenes de marginalidad urbana posibilidades de construir un mundo mejor a partir de la potencia de cambio social que surge del territorio. A diez años de su publicación, La Virgen Cabeza sigue funcionando como un reloj literario y político que adelanta.
La literatura de mujeres como archivo hospitalario: una propuesta
Authors: Szurmuk Mónica , Virué Alejandro
Published: June 2020

En este trabajo analizaremos el aporte específico de la literatura en la recuperación y la construcción de la historia de las mujeres. A partir de las reflexiones de Jaques Derrida, proponemos el concepto de archivo hospitalario para pensar no solo la selección de un corpus sino una forma de abordarlo desde las teorías del presente, ya sea para, desde la crítica, dar cuenta de aquello que en ese corpus aparece apenas sugerido o de manera cifrada; ya sea para recrear, desde la ficción, imágenes que dialoguen y expandan ciertos tópicos que, en el contexto de su producción, pudieron resultar extemporáneos o impensables. Desde esta perspectiva analizaremos obras de Sor Juana Inés de la Cruz (y su actualización en una performance de Jesusa Rodríguez), Sabina Berman, Lina Beck Bernard y Tununa Mercado.
Por un «materialismo de la relación». Una lectura de Pájaros en la boca de Samanta Schweblin
Authors: Fioretti Lorena , Manini Gabriela
Published: June 2020

Proponemos trabajar en este texto la escritura de la argentina Samanta Schweblin. Sostenemos que es posible leer en su apuesta narrativa un modo de comprender lo que llamaremos un «materialismo de la relación» como un materialismo que surge del encuentro de la propuesta althusseriana y la derridiana en torno a la cuestión del materialismo no dialéctico. A partir de la articulación con el libro de cuentos Pájaros en la boca (2018) como un «espacio textual», es decir, como un recorte territorial, no una dirección teórica, sino ideológica, histórica y genealógica, pretendemos ensayar una lectura sintomal, pero también deconstructiva, que trabaje desde este materialismo relacional en la pregunta por la relación entre arte y política. Entendemos que desde esta lectura materialista el modo de articulación entre arte y política se sostiene en el trabajo particular con la letra, en los modos en que la trama conjura contra los códigos y las representaciones que este genera alrededor de un Sentido (moral, del tiempo, de las figuraciones de la conciencia de los personajes); y, correlativamente, en su efecto, en lo que la estructura de la pieza literaria pone en movimiento como resonancia en su rechazo a ser un comentario especular y mistificador el mundo.
Plasticidad de las formas o cartografías del deseo. Una lectura de La mujer desnuda de Armonía Somers
Authors: Lorio Natalia
Published: June 2020

Nos interesa en este texto plantear una lectura de La mujer desnuda de Armonía Somers desde un materialismo del deseo. Para ello no solo postulamos una suerte de cartografía del deseo (entendido como revelación de un vacío, esencialmente distinto de la realidad estática y dada, es decir, como inquietud y negación), sino que también apostamos por su puesta en relación con una forma de materialidad (desde la propuesta de plasticidad de Malabou) donde el cuerpo, el contacto y el contagio son asumidos desde un materialismo donde la forma no coincide con su presencia. El materialismo que está puesto en juego en esta nouvelle de Somers (¿un materialismo erótico?) permite, por un lado reconocer en su personaje al deseo mismo (sin objeto, deseo de deseo) y, por otro, cartografiar en sus movimientos, la plasticidad de las formas que se juegan como la apertura a la forma del otro en sí mismo: convertibilidad de la forma y el deseo in–humanos para ir más allá de la noción de comunidad, pensando en esas formas y experiencias que se dan entre la soledad y la comunidad, entre la muchedumbre y la singularidad.

Published: June 2020

Based on data from Badan Pusat Statistik (BPS), the number of Indonesia's population has consistently increased every year. This will cause several problems, one of them is public health. Health problems that occur cause some risks that cause losses. Therefore, one way to reduce the impact of these risks is insurance. This study analyzes how the process of forming premium prices with loading assumptions that are in accordance with existing assumptions in order to meet the criteria of equitable to the client, deliverable by the agent, and profitable to the company. This research uses a quantitative research approach. The population in this study was all Sum Insured (SI) while the sample was 1000 SI male sex. The data used in this study are secondary data that is data from an ABC insurance company in Indonesia, literature study through books, journal references, and previous research. The results of this study are the calculation of premiums by the methods used by the company more efficiently when compared with formulas in accordance with the theory. Although the price of a premium is more expensive using the company method, it is not significantly different. If using the company method, the sum insured used is the sum insured from death benefit whereas the theory is the average of claims incurred at that age. The fees charged are still fairly reasonable in accordance with the rules of setting the price of insurance premiums. In addition, the use of CSO 80 tables and Reinsurance Rates that have been adjusted to the company's interest rate of 5% in accordance with the expected cash value desired by the company.

Published: June 2020

Imbalanced data might cause some issues in problem definition level, algorithm level, and data level. Some of the methods have been developed to overcome this issue, one of state-of-the-art method is Easy Ensemble. Easy Ensemble was claimed can improve model performance to classify minority class, and overcome the deficiency of random under- sampling. In this paper we discussed the implementation of Easy Ensemble with Random Forest Classifiers to handle imbalance problem in credit scoring case. This combination method is implemented in two datasets which taken from data science competition website, finhacks.id and kaggle.com with class proportion within majority and minority is 70:30 and 94:6. The results showed that resampling with Easy Ensemble can improve Random Forest classifier performance upon minority class. Recall on minority class increased significantly after the resampling. Before resampling, the recall on minority class for the first dataset (finhacks.id) was 0.49, and increased to 0.82 after the resampling. Similar results were obtained for the second data set (kaggle.com), where the recall for the minority class was increased from just 0.14 to 0.73.

Kant, Eudaimonism, Act-Consequentialism and the Fact of Reason
Authors: Sticker Martin
Published: June 2020

Kant considers eudaimonism as his main opponent and he assumes that his ethics is the only viable alternative to eudaimonism. He does not explicitly address theories differing from both eudaimonism and from his own. I argue that whilst Kant and Act-Consequentialists advocate different normative principles, their positions share the important abstract feature that they establish what is to be done from a rational principle and not based on what is in the self-interest of the respective agent, as Kant thinks eudaimonism does. Act-Consequentialism is thus closer to Kant’s ethics than is often assumed. I will demonstrate and vindicate this point with a new interpretation of the Fact of Reason. This reading also establishes that the notion of a Fact of Reason is less contentious than many of Kant’s critics believe. We should not expect that the Fact establishes Kantianism. Instead, the Fact is only supposed to count against a specific competing view of morality, namely, eudaimonism. Act-Consequentialists can accept the Fact as well.
Bolstering the Keystone: Kant on the Incomprehensibility of Freedom
Authors: Aylsworth Timothy
Published: June 2020

In this paper, I give an explanation and defense of Kant’s claim that we cannot comprehend how freedom is possible. I argue that this is a significant point that has been underappreciated in the secondary literature. My conclusion has a variety of implications both for Kant scholars and for those interested in Kantian ideas more generally. Most notably, if Kant is right that there are principled reasons why freedom is beyond our comprehension, then this would release his ethical views from an undesirable explanatory burden. It would be a boon for Kantians if they could ground their lofty claims about the unique, elevated status of rational agency without committing to an implausible view of libertarian freedom. I also suggest that there are certain debates concerning moral motivation and transcendental idealism that might have to change in response to Kant’s claims about the incomprehensibility of freedom.
Comparison of dynamic balancing responses following outward lateral perturbations during walking of healthy and post-stroke subjects

Published: June 2020

Efficient dynamic balancing and movement coordination during walking are essential for stability. The objective of this preliminary study was to assess dynamic balancing responses in a selected post-stroke subject and to compare them with those assessed in neurologically intact individual. Balance Assessment Robot, a haptic robot that interfaces to a pelvis of a subject walking on an instrumented treadmill, was used to deliver perturbing pushes to the pelvis. We have assessed centre-of-pressure (CoP) and horizontal components of ground reaction forces (GRF) following outward pushes. The results have shown that depending on the amplitude of a perturbing push neurologically intact individual responded predominantly by “ankle” and “hip” strategies at lower amplitude of perturbation and “ankle” and “stepping” strategies at higher amplitude of perturbation. Post-stroke subject responded mainly by “ankle” and “hip” strategies when perturbed on the sound leg while the response when perturbed on the impaired leg was similar to the one observed in healthy subject. These preliminary results indicate that post-stroke subjects might be reluctant or not able to perform “cross step” with their impaired leg which is needed when counteracting outward perturbation.
Compensating the effects of FES-induced muscle fatigue by rehabilitation robotics during arm weight support

Published: June 2020

Motor functions can be hindered in consequence to a stroke or a spinal cord injury. This often results in partial paralyses of the upper limb. The effectiveness of rehabilitation therapy can be improved by the use of rehabilitation robotics and Functional Electrical Stimulation (FES). We consider a hybrid arm weight support combining both. In order to compensate the effect of FES-induced muscle fatigue, we introduce a method to substitute the decreasing level of FES support by cable-driven robotics. We evaluated the approach in a trial with one healthy subject performing repetitive arm lifting. The controller automatically adapted the support and thus no increase in user generated volitional effort was observed when FES induced muscle fatigue occured.
Adjustment of instantaneous reference walking speed during synchronized robot-based gait rehabilitation
Authors: Martinez Santiago Focke , Kuzmicheva Olena , Graeser Axel
Published: June 2020

This paper presents a method to adjust the instantaneous reference speed of the mobile platform or treadmill of robotic gait rehabilitation systems during compliant, synchronized therapy. This method is particularly useful when the robot-patient synchronization algorithms generate compensations that fluctuate significantly throughout the gait cycle, making it unsuitable to apply these compensations directly to the reference speed values. The method was tested with a synchronization algorithm that generates continues temporal-compensations based on a phase controller. The tests comprised simulation of different scenarios and a practical test with a healthy subject using an over-ground gait rehabilitation system.
Design of a pressure sensitive matrix for analyzing direct haptic patient-therapist interaction in motor rehabilitation after stroke
Authors: Pust Michael , Ivanova Ekaterina , Schmidt Henning , Krüger Jörg
Published: June 2020

Robot based therapy is one of the prevalent therapeutic approaches in motor stroke rehabilitation. It is often used in hospitals in combination with conventional therapy. In order to optimize human-robot interaction, we aim to investigate how a therapist physically supports patients during motor training of the upper extremities. This paper presents the design of a flexible textile sensor matrix, which measures the pressure exerted between therapist and patient during direct haptic interaction as well as the hand position and orientation in space. The matrix contains 144 sensors which enables measuring pressure intensity and localization of areas where the pressure is applied. The measurement matrix was evaluated with four healthy participants.
Lipase-catalyzed synthesis and post-polymerization modification of new fully bio-based poly(hexamethylene γ-ketopimelate) and poly(hexamethylene γ-ketopimelate-co-hexamethylene adipate) copolyesters
Authors: Wu Wan-Xia
Published: June 2020

A novel full bio-based ketone-containing aliphatic polyester was prepared by enzyme-catalyzed polycondensation of diethyl γ-ketopimelate (DEK) with 1,6-hexanediol (HDO) using immobilized lipase B from Candida antarctica (CALB). The influences of polymerization conditions such as temperature, time, enzyme amount, and solvent amount on the molecular weight of poly(hexamethylene γ-ketopimelate) (PHK) were investigated. New fully bio-based poly(hexamethylene γ-ketopimelate-co-hexamethylene adipate) (poly(HK-co-HA)) copolymers with narrow polydispersity and well-defined composition were synthesized by copolymerization of DEK, HDO, and diethyl adipate. The structures of PHK and poly(HK-co-HA) copolymers were characterized by nuclear magnetic resonance, and their thermal characterization was examined by thermogravimetric analysis and differential scanning calorimetry. The degradation of PHK and poly(HK-co-HA) copolymers was studied. The post-polymerization modification of these polyketoesters via oxime click chemistry was further demonstrated.
Functions of early Iron Age handstones. Experimental and traceological approach.

Published: June 2020

The multi-faceted analyses proved that the community of early Iron Age settlement (7th century BC) at Milejowice in SW Poland used easily accessible, erratic pebbles of similar shapes for various purposes. Referring to the results of our experimental work, we examined a collection of 46 stone objects found in various contexts. Using microscopic analysis of use-wear, we identified the handstones for grinding grain and plant stalks and also used for pottery production (grog obtaining) and decoration (red pigment powdering). Some of the handstones served for only one purpose, while the other might have been used to process both hard and soft materials. The distribution of the handstones in the settlement area showed that they were strongly associated with household activities which included both food processing and pottery manufacturing.
Czech analytic agreement and the characteristics of littlepro
Authors: Veselovská Ludmila
Published: June 2020

This study deals with subject predicate agreement in Czech and the structure of a null subject. First, it introduces the concept of Null Subject Languages as it has been used in a generative framework. Then it shows the complex feature content of the Czech subject-predicate agreement morphology, arguing that the data repeatedly signal a division of the agreement features into two clear cut feature sets and two distinct agreement domains: (a) the lower, lexical domain insidevP containing the nominal n[±φ]feature set (Gender and N-Number), and (b) the higher, functional domain on the T head, which contains the functional D[±φ]feature set (Person and D-Number). The study relates the analysis to the present day microparametric concept of a Null Subject Parameter as in, e. g., the studies in Biberauer (2010), accepting the hypothesis of the checking of the subject-predicate agreement with two levels of predicate (separate headsvand T). It proposes that with pronominal subjects, the φ feature values can be re-set with respect to the speech act information located in the Aboutness Topic. Given the several levels of agreement, each of which can be licensed by a zero morpheme, the study proposes thatprois a complex entity consisting of two separate parts, each endowed with a distinct set of φ features.
Definiteness markers in theLife of St Petka
Authors: Šimko Ivan
Published: June 2020

The following paper addresses the problem of the diachronic development of definiteness markers in Bulgarian as attested in literature. As the previous research focused on the postponed article as the main definiteness marker in present-day Bulgarian, our study compares its use with that of other markers, namely the long-form adjective and the adnominal demonstrative pronoun. The traditional view sees a steady convergence between the literary norm and the dialectal use of the article. To challenge this view, we observe the frequency of use of all definiteness markers on an empirical basis. Оur study uses a sample containing six versions of the hagiography of St Petka of Tarnovo, also known as St Parascheva of Epibates. The text for this study is provided by a historical corpus of pre-standardized Balkan Slavic literature, which is being constructed to enable us comparisons between the dialectal and diachronic data. The samples are chosen to minimalize the effects of genre, structure and content differences on the results. The frequency of individual types of definiteness markers in respective versions of the text shows that the development of the damaskini language was not only different in respect to dialectal developments in the area, but in some respects even contrary to them.
