The effect of employees’ sense of power on supervisors’ voice endorsement: A cross-level moderated mediation model
Authors: Yuan Ping , Cheng Yuan , Liu Yanbin , Ju Fanghui
Published: October 2022

Based on expectation states theory, we examined the mechanism underlying the effect of employees’ sense of power on supervisors’ voice endorsement, and tested our hypothesized model on a sample of 307 employees from 60 work teams. We used a two-time lagged design and paired questionnaire survey. Our analysis indicated that employees’ sense of power enhanced supervisors’ voice endorsement, and supervisors’ perceived voice constructiveness mediated this relationship. Multilevel analyses showed that power distance negatively moderated the influence of sense of power on perceived voice constructiveness and negatively moderated its indirect effect on voice endorsement.
A hybrid Chinese word segmentation model for quality management-related texts based on transfer learning
Authors: Wen Peihan , Feng Linhan , Zhang Tian
Published: October 2022

Text information mining is a key step to data-driven automatic/semi-automatic quality management (QM). For Chinese texts, a word segmentation algorithm is necessary for pre-processing since there are no explicit marks to define word boundaries. Because of intrinsic characteristics of QM-related texts, word segmentation algorithms for normal Chinese texts cannot be directly applied. Hence, based on the analysis of QM-related texts, we summarized six features, and proposed a hybrid Chinese word segmentation model by means of integrating transfer learning (TL), bidirectional long-short term memory (Bi-LSTM), multi-head attention (MA), and conditional random field (CRF) to construct the mTL-Bi-LSTM-MA-CRF model, considering insufficient samples of QM-related texts and excessive cutting of idioms. The mTL-Bi-LSTM-MA-CRF model is composed of two steps. Firstly, based on a word embedding space, the Bi-LSTM is introduced for context information learning, and the MA mechanism is selected to allocate attention among subspaces, and then the CRF is used to learn label sequence constraints. Secondly, a modified TL method is put forward for text feature extraction, adaptive layer weights learning, and loss function correction for selective learning. Experimental results show that the proposed model can achieve good word segmentation results with only a relatively small set of samples.

Published: October 2022

Herein we report the use of an environmental multimetal(loid)-resistant strain, MF05, to biosynthesize single- or multi-element nanostructures under anaerobic conditions. Inorganic nanostructure synthesis typically requires methodologies and conditions that are harsh and environmentally hazardous. Thus, green/eco-friendly procedures are desirable, where the use of microorganisms and their extracts as bionanofactories is a reliable strategy. First, MF05 was entirely sequenced and identified as an Escherichia coli-related strain with some genetic differences from the traditional BW25113. Secondly, we compared the CdS nanostructure biosynthesis by whole-cell in a design defined minimal culture medium containing sulfite as the only sulfur source to obtain sulfide reduction from a low-cost chalcogen reactant. Under anaerobic conditions, this process was greatly favored, and irregular CdS (ex. 370 nm; em. 520–530 nm) was obtained. When other chalcogenites were tested (selenite and tellurite), only spherical Se0 and elongated Te0 nanostructures were observed by TEM and analyzed by SEM-EDX. In addition, enzymatic-mediated chalcogenite (sulfite, selenite, and tellurite) reduction was assessed by using MF05 crude extracts in anaerobiosis; similar results for nanostructures were obtained; however Se0 and Te0 formation were more regular in shape and cleaner (with less background). Finally, the in vitro nanostructure biosynthesis was assessed with salts of Ag, Au, Cd, and Li alone or in combination with chalcogenites. Several single or binary nanostructures were detected. Our results showed that MF05 is a versatile anaerobic bionanofactory for different types of inorganic NS. synthesis.

Published: October 2022

This work identifies the factors that influence the perception of company managers regarding the state support programs carried out in times of Covid19. A questionnaire was applied to a sample of company executives from the city of Talca, Chile. Descriptive, exploratory factor analysis and structural modeling ratified by the relevant goodness of fit indices were carried out. The results confirm the existence of three factors that affect the perception of managers that include 12 significant items. It is concluded that the investment factor acts as an independent dimension in the model, the classification factor of the companies acts as a mediator and finally the competitiveness factor turns out to be the dependent dimension of the model.
Income assistance use among young adults who were in British Columbia special education: A longitudinal cohort study
Authors: Scott Craig William Michael , Russell Matthew Joseph , Tough Suzanne , Zwicker Jennifer D.
Published: October 2022

Background

Persons with disability (PWD) experience disproportionately high poverty rates in Canada. This trend is apparent especially among youth compared to those who develop disabilities later in life. PWD in poverty have additional needs that increase barriers to full participation in society and translate to higher basic costs for daily living. Despite the existence of income assistance programs in Canada to mitigate income inequalities faced by PWDs, access to these programs can be limited.

Objective

To describe use of income assistance for young adults with disability in British Columbia for the development of potential approaches to improve realized access to these programs.

Methods

We conducted a population-based retrospective cohort study using British Columbia linked administrative data. We described differences in income assistance use among PWD by the level of special education funding received during primary school education (from most to least; Level 1, Level 2, Level 3, Unfunded, and no special education) and family composition. We also provided longitudinal patterns of income assistance use.

Results

Of 218,324 young adults, 88% received no special education, 0.1% used Level One, 1.6% used Level Two, 2.9% used Level Three, and 7.1% used Unfunded special education coding. Young adults with Level One special education funding had the highest rates of hospitalizations and continuing care, with no hospitalization due to homelessness. Those with Level Three special education coding had higher rates of hospitalization and hospitalization due to homelessness than Level Two young adults. When transitioning to adulthood initially, Level One and Two funded individuals used relatively more disability income assistance than individuals from the other funding levels. Nearly all BCEA users with higher funded special education codes used this disability-specific program, while lesser funded special education codes used the Temporary Assistance more frequently, for a longer duration and were more likely to be persistent Temporary Assistance users.

Conclusions

Sustainable and reliable access to income assistance programs remains an issue across the heterogeneity of needs faced by young adults with disability.

Published: October 2022

Background

Health care workers (HCWs) in the first line of care play critical roles in providing the correct information about the coronavirus disease to the community. The objective of the study was to determine the effect of virtual training on the knowledge, attitude, and preventive practices among PHC workers and their clients in the prevention and control of coronavirus disease.

Methods

A quasi-experimental intervention virtual training, using a before and after design amongst HCWs and clients was conducted at primary health care facilities in two Local Government Areas of Lagos State. The study instruments were pre-tested questionnaires for both HCWs and their clients. which investigated knowledge of symptoms, modes of disease transmission, methods of prevention, and preventive practices. Changes in knowledge, attitudes, and practices were compared pre-and post-intervention. The level of significance was set at p < 0.05.

Results

Sixty-three HCWs (out of 100 recruited at baseline) and 133 clients (out of the initial 226) completed the study. The mean ages of the HCWs and clients were 39.2±9.9 and 30.9±5.0 years respectively. At the baseline, the HCW’s knowledge was good in the domains of symptoms, modes of transmission, and preventive measures. The training led to a higher but not significant (p> 0.05) increase in the level of knowledge. Contact with trained HCWs was found to lead to significantly (P < 0.001) higher levels of knowledge, attitudes, and preventive practices. amongst clients.

Conclusion

The training was effective in improving the knowledge of both the trained HCWs and their clients.

Published: October 2022

Background

Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract. We aimed to investigate, for the first time, the expression profile of serum level of LncRNA THRIL and MiR-125b in IBD patients and their relations with patient’s clinical and biochemical investigations.

Methods

Our study included 210 subjects divided into 70 healthy subjects considered as control group (male and female), 70 patients with ulcerative colitis (UC), and 70 patients with Crohn’s disease (CD). Blood samples were obtained from all subjects. Expression of LncRNA THRIL and MiR-125b in serum was detected by Quantitative real time PCR (qRT-PCR).

Results

Our results showed a significant increase in the fold change of LncRNA THRIL in UC patients (Median = 11.11, IQR; 10.21–12.45, P<0.001) and CD patients (Median = 5.87, IQR; 4.57–7.88, P<0.001) compared to controls. Meanwhile there was a significant decrease in the fold change of MiR-125b in UC patients (Median = 0.36, IQR; 0.19–0.61, P<0.001) and CD patients (Median = 0.69, IQR; 0.3–0.83, P<0.001) compared to controls. Furthermore, there was a negative significant correlation between LncRNA THRIL and MiR-125b in UC patients (r = -0.28, P = 0.016) and in CD patients (r = -0.772, P<0.001). ROC curve analysis was done showing the diagnostic value of these markers as predictors in differentiating between cases of UC, CD, and control.

Conclusion

Serum LncRNA THRIL and MiR-125b could be used as potential biomarkers for diagnosis and prognosis of ulcerative colitis and Crohn’s disease.

Published: October 2022

Disturbance gradients are particularly useful for understanding the relative influences of competition and dispersal. Shortly after disturbance, plant composition should be influenced more strongly by dispersal than competition; over time, this should reverse, with competition becoming more important. As such, we predicted that plant functional traits associated with high dispersal ability would be over-represented shortly after a disturbance event occurs, while those associated with high competitive ability would have increased representation as time progresses. Additionally, it has been suggested that competitive interactions may contribute to negative co-occurrence patterns; if this is the case, negative co-occurrence patterns should also increase as time-since-disturbance increases. Here, we examine how functional trait and co-occurrence patterns change over time following a herbicide-based disturbance, compared to undisturbed vegetation, in a temperate, old-field grassland dominated by herbaceous perennials. In our study system, negative co-occurrence patterns were most pronounced in disturbed plots one year after herbicide application, consistent with several lines of evidence that dispersal can strongly impact both composition and co-occurrence patterns. Over three years post-disturbance, co-occurrence patterns in disturbed plots decreased, becoming more similar to control plots. This pattern is inconsistent with the expectation that competition contributes to negative co-occurrence patterns, at least over three growing seasons. More pronounced negative co-occurrence patterns were associated with higher species evenness among plots. Functional traits related to increased dispersal (mean seed mass, and proportion of stoloniferous/rhizomatous species) and competitive ability (mean species height, and mean specific leaf area) did not differ significantly across treatments, with the exception of mean height in the third-year post-disturbance; however, the overall trajectory of this trait was inconsistent with theoretical expectations. Overall, co-occurrence patterns changed across the gradient of time-since disturbance, but not as expected; functional trait patterns (trait means, functional diversity measures) were not responsive to our experimental disturbance gradient.

Authors: Polessa Paula Daniela , Barbosa Aguiar Odaleia , Pruner Marques Larissa , Bensenor Isabela , Suemoto Claudia Kimie , Mendes da Fonseca Maria de Jesus , Griep Rosane Härter
Published: October 2022

Background

Multimorbidity is a worldwide concern related to greater disability, worse quality of life, and mortality. The early prediction is crucial for preventive strategies design and integrative medical practice. However, knowledge about how to predict multimorbidity is limited, possibly due to the complexity involved in predicting multiple chronic diseases.

Methods

In this study, we present the use of a machine learning approach to build cost-effective multimorbidity prediction models. Based on predictors easily obtainable in clinical practice (sociodemographic, clinical, family disease history and lifestyle), we build and compared the performance of seven multilabel classifiers (multivariate random forest, and classifier chain, binary relevance and binary dependence, with random forest and support vector machine as base classifiers), using a sample of 15105 participants from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). We developed a web application for the building and use of prediction models.

Results

Classifier chain with random forest as base classifier performed better (accuracy = 0.34, subset accuracy = 0.15, and Hamming Loss = 0.16). For different feature sets, random forest based classifiers outperformed those based on support vector machine. BMI, blood pressure, sex, and age were the features most relevant to multimorbidity prediction.

Conclusions

Our results support the choice of random forest based classifiers for multimorbidity prediction.
LSTM input timestep optimization using simulated annealing for wind power predictions
Authors: Muneeb Muhammad
Published: October 2022

Wind energy is one of the renewable energy sources like solar energy, and accurate wind power prediction can help countries deploy wind farms at particular locations yielding more electricity. For any prediction problem, determining the optimal time step (lookback) information is of primary importance, and using information from previous timesteps can improve the prediction scores. This article uses simulated annealing to find an optimal time step for wind power prediction. Finding an optimal timestep is computationally expensive and may require brute-forcing to evaluate the deep learning model at each time. This article uses simulated annealing to find an optimal time step for wind power prediction. The computation time was reduced from 166 hours to 3 hours to find an optimal time step for wind power prediction with a simulated annealing-based approach. We tested the proposed approach on three different wind farms with a training set of 50%, a validation set of 25%, and a test set of 25%, yielding MSE of 0.0059, 0.0074, and 0.010 for each wind farm. The article presents the results in detail, not just the mean square root error.
Capturing the experiences of UK healthcare workers during the COVID-19 pandemic: A structural topic modelling analysis of 7,412 free-text survey responses

Published: October 2022

Background

Healthcare workers (HCWs) have provided vital services during the COVID-19 pandemic, but existing research consists of quantitative surveys (lacking in depth or context) or qualitative interviews (with limited generalisability). Structural Topic Modelling (STM) of large-scale free-text survey data offers a way of capturing the perspectives of a wide range of HCWs in their own words about their experiences of the pandemic.

Methods

In an online survey distributed to all staff at 18 geographically dispersed NHS Trusts, we asked respondents, “Is there anything else you think we should know about your experiences of the COVID-19 pandemic?”. We used STM on 7,412 responses to identify topics, and thematic analysis on the resultant topics and text excerpts.

Results

We identified 33 topics, grouped into two domains, each containing four themes. Our findings emphasise: the deleterious effect of increased workloads, lack of PPE, inconsistent advice/guidance, and lack of autonomy; differing experiences of home working as negative/positive; and the benefits of supportive leadership and peers in ameliorating challenges. Themes varied by demographics and time: discussion of home working decreasing over time, while discussion of workplace challenges increased. Discussion of mental health was lowest between September-November 2020, between the first and second waves of COVID-19 in the UK.

Discussion

Our findings represent the most salient experiences of HCWs through the pandemic. STM enabled statistical examination of how the qualitative themes raised differed according to participant characteristics. This relatively underutilised methodology in healthcare research can provide more nuanced, yet generalisable, evidence than that available via surveys or small interview studies, and should be used in future research.

Authors: Ko Chen-Yu , Yao Chih-Chien , Li Yu-Chi , Lu Lung-Sheng , Chou Yeh-Pin , Hu Ming-Luen , Chiu Yi-Chun , Chuah Seng-Kee , Tai Wei-Chen
Published: October 2022

Background and aims

Endoscopic submucosal dissection (ESD) as an advanced endoscopic procedure can be considered for the removal of colorectal lesions with high suspicion of limited submucosal invasion or cannot be optimally removed by snare-based techniques. We aimed to analyze the clinical outcomes of ESD for colorectal neoplasms in our hospital.

Methods

We retrospectively enrolled 230 patients with 244 colorectal neoplasms who received ESD procedures from April 2012 to October 2020 at Kaohsiung Chang Gung Memorial Hospital. Clinicopathological data were collected by chart review. We also recorded ESD-related complications and clinical outcomes.

Results

The average age was 64 years old, with a mean follow-up time of 22.59 months. There was a loss of follow-up in 34 lesions. Most lesions were lateral spreading tumors of the non-granular type. The average ESD time was 51.9 minutes. Nine cases (3.7%) had procedure-related complications, including two intra-procedure perforations (0.8%) and seven delayed bleeding (2.9%) without procedure-related mortality. 241 lesions (98.8%) achieved en-bloc resection, while 207 lesions (84.8%) achieved R0 resection. Most lesions were tubulo-(villous) adenoma. Malignancy included 35 adenocarcinomas and 5 neuroendocrine tumors. No local recurrence was developed during follow-up. Multivariate analysis for long ESD time revealed significance in size ≥ 10 cm2 and endoscopist’s experience < 3 years. Pre-ESD endoscopic ultrasound revealed good prediction in discrimination of mucosal (sensitivity: 0.90) and submucosal lesion (specificity: 0.67).

Conclusions

ESD for colorectal neoplasms is an effective and safe technique. Size ≥ 10 cm2 and endoscopist’s experience < 3 years were significantly associated with long procedure time. Pre-ESD EUS provided a good prediction for colorectal neoplasms in invasion depth.
Translation and validation of the Arabic version of the Morisky, Green and Levine (MGL) adherence scale

Published: October 2022

The Morisky Green Levine (MGL) adherence scale is a 4-item tool used for the detection of medication nonadherence among patients with chronic health conditions. Despite being widely used in Arabic-speaking research contexts, it has never been validated in Arabic language. The aim of this study was to translate and validate the MGL tool into Arabic. A standard forward-backward process was used to translate the questionnaire. Cronbach’s alpha coefficient was measured to assess internal consistency of the scale. The test-retest reliability measured the consistency of participants’ responses over time. Construct validity was evaluated by Explanatory factor analysis (EFA); Kaiser-Meyer-Olkin value and Bartlett’s test of sphericity were determined. Convergent validity was assessed using a preexisting medications Arabic Adherence Assessment Tool (AAAT). The model fit was evaluated using confirmatory factor analysis (CFA). Associations between the MGL scale scores and the patient demographic/clinical characteristics were tested by linear regressions. A total of 201 participants were included into the study. The MGL scale categorization revealed that 20.9%, 59.2% and 19.9% of the participants had high, moderate and low levels of adherence respectively. Adequate internal consistency (alpha = 0.593) was observed. A significant strong ICC and Pearson’s correlations were generated between responses at time 1 and time 2. EFA results elucidated the suitability of the data for factor analysis. Pearson’s coefficient (r) revealed a significant strong correlation between MGL scale and AAAT. CFA results confirmed a good fit for the suggested model. Linear regression revealed higher number of medications, more frequent outpatient clinic visits and not experiencing medication adverse effect factors significantly associated with better adherence. The Arabic version of MLG scale is a reliable valid tool to assess adherence among Arabic-speaking communities. Implementing interventions targeting patients not compliant to regular clinic visits and those at higher risk of experiencing medication side effects can greatly enhance medication adherence.
Effects of abscisic acid on growth and selenium uptake in medicinal plant Perilla frutescens
Authors: Liao Renyan
Published: October 2022

The aim of the present study was to explore the effects of abscisic acid (ABA) on growth and selenium (Se) absorption of the medicinal plant, Perilla frutescens. A pot experiment was conducted to evaluate the effects of different ABA concentrations (0, 1, 5, 10 and 20 μmol/L) on the physiological characteristics and Se absorption capacity of P. frutescens. Application of 5, 10 and 20 μmol/L ABA increased the shoot biomass of P. frutescens, and only 5 and 10 μmol/L ABA increased the root biomass. Application of 5, 10, and 20 μmol/L ABA increased the contents of photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid), superoxide dismutase activity, peroxidase activity, and soluble protein content of P. frutescens, and decreased the malondialdehyde content in P. frutescens. Only 5 and 10 μmol/L ABA used in the present study increased the catalase activity of P. frutescens. For the Se uptake, only 5 μmol/L ABA increased the Se content, Se extraction and Se bioconcentration factor of both roots and shoots. The findings of the present study indicate that 5 and 10 μmol/L ABA promotes the growth of P. frutescens, whereas 5 μmol/L ABA enhances the Se accumulation capacity in P. frutescens.

Published: October 2022

The article is devoted to modeling the potential distribution area of the species Pulsatilla turczaninovii Kryl. et Serg. Plant ecological niche modeling is the process of building models using modern computer algorithms and bioclimatic data to predict the distribution range of plant species. The result of the simulation is a model that can be used to map the area of growth or residence of species, predict the range or analyze the impact of the environment on species.

Data are required on both the presence of species and their absence in a particular territory to build effective models for predicting ecological niches of plants. View absence points (or background points) are not registered in databases, but can be generated using different approaches.

This article describes the implementation of three approaches to selecting pseudo-absence points of species in an operationally divided territory and presents the result of modeling the potential distribution area of the species Pulsatilla turczaninovii Kryl. et Serg. using the random forest algorithm — the most popular way to build ensembles of decision trees. The software implementation of the model is carried out in the high-level Python programming language.

Goal: The purpose of this study is to analyze how the elements of industry 4.0 relate to Supply Chain Management (SCM) by identifying mechanisms that promote or include these elements in the supply chain. The elements of industry 4.0 relate to the basic processes of Supply Chain Operations Reference (SCOR) when considering the literature on the subject.
Design / methodology / approach: A systematic literature review was performed, and 126 articles were selected and analyzed. Content analyses were conducted to identify the main contributions of elements in SCM, explaining the mechanisms that promote or include elements in SCM and relating the elements to the basic processes of the SCOR model.
Results: From the literature analysis, theoretical relations between the elements of industry 4.0 and SCM were established. An overview on the subject was provided, filling a gap in the literature. Identifying the mechanisms that promote or include elements in supply chains and the relations of elements to the SCOR model may help to guide managers for future applications of this model in a targeted manner.
Limitations of investigation: This study covers only theoretical analysis on the concepts, that is, no real applications were made considering the topics addressed.
Originality / value: The construction of a theoretical framework based on systematic literature review on SCM and Industry 4.0 is a contribution to the bibliographic database. Another contribution is the identification and analysis of the main contributions of elements to SCM in the processes of the SCOR model.

„Nie z nienawiścią, lecz z pogardą patrzy kot na psa”. Čapkowskie uwagi na temat psychiki zwierzęcej
Authors: Gawarecka Anna
Published: October 2022

Książka Karla Čapka Měl jsem psa a kočku (Miałem psa i kota) ukazała się (pośmiertnie) w 1939 roku na czeskim rynku wydawniczym. Publikacja ta, składająca się z kilku esejów, opowieści o foksterierze Dášeńce i humorystycznego przewodnika po rasach psów, była traktowana przez badaczy literatury głównie jako swego rodzaju hybrydyczny bricolage różnych gatunków literackich i publicystycznych. Zamieszczone w niej opowieści o zwierzętach czerpią materiał tematyczny z codziennej i empirycznej obserwacji i nie wymagają korzystania z systemów kulturowych odniesień i wyobrażeń. Ich odbiór wymaga jednak wiedzy powszechnej, dostępnej dla tych (czyli właściwie dla wszystkich), którzy mieli do czynienia ze zwierzętami domowymi i dzięki temu są w stanie potwierdzić te spostrzeżenia, skonfrontować je z własnym doświadczeniem i w efekcie docenić trafność i wnikliwość diagnoz przedstawionych przez autora. Paradoksalne konkluzje, które Čapek wywodzi ze swych spostrzeżeń, wytrącają czytelnika z rutyny poznawczej i pokazują, że problem życia emocjonalnego i intelektualnego zwierząt jest bardziej skomplikowany, niż to się zwykło uważać. Narracyjne portrety psich i kocich bohaterów służą przede wszystkim budowaniu modeli antropologicznych, dla których wzorce zachowań zwierząt stanowią przekonującą (bo sprowadzoną do uproszczonych „podstawowych” matryc behawioralnych) egzemplifikację.

Czerwone wampiry. Geneza i funkcjonowanie kulturowego dyskursu lustmordu w PRL
Authors: Kamińska Magdalena
Published: October 2022

Artykuł omawia genezę dyskursu zabójstw z motywów seksualnych, których sprawcy nazywani byli „zabójcami z lubieżności”, a potocznie „wampirami”. Postaci te przedstawiane były – zgodnie z formatem ukształtowanym przez kryminalistykę i prasę początku XX wieku – jako emanacje silnie przekształconego antropogennie woundscape’u ( M. Seltzer ). Proces konstruowania postaci „wampira” poprzez othering wchodził tym samym w konflikt z dynamiką procesów modernizacji. Po następujących po sobie przełomach politycznych opowieści o „wampirach” poddawano kolejnym rewizjom, a obecnie w Polsce narracje o ich czynach wpisują się w hauntologiczny nurt „peerelowskiego gotyku”.
Central European Cultural Transfers in the Humanism and Baroque Periods: Three Examples from Literary History
Authors: Malura Jan
Published: October 2022

This study investigates cultural transfer in Central Europe in the sixteenth and seventeenth centuries. It focuses on three different fields ( parody Protestant religious song, Christmas drama ) and explores the directions and mechanisms of cultural exchange and the role of mediators in the dissemination of selected literary phenomena. The observation of cultural transfers confirms to some extent the traditional idea of the journey of cultural work from the West to the East. However, the individual transfers are significantly influenced by specific cultural contexts. The social, ethnic and religious situation strongly connected cultural life in the Czech lands with the literary models available in the north-east and southern regions of Germany, while Polish cultural traffic, with a few exceptions, is rather distant from these areas, though. The conditions in Silesia were specific, because a significant share of the population was German and a strong multi-confessional situation prevailed there.
Postkolonializm w konflikcie
Authors: Tomczok Marta
Published: October 2022

W artykule analizuję koncepcję postkolonializmu w konflikcie, zaproponowaną w pracy Polska literatura postkolonialna. Od sarmatyzmu do migracji poakcesyjnej (2020) Dirka Uffelmanna. Nawiązując do najważniejszych prac badaczy polskich (Hanny Gosk, Doroty Kołodziejczyk, Magorzaty Zduniak-Wiktorowicz, Ryszarda Nycza), staram się pokazać założenia myśli niemieckiego slawisty, a także zrozumieć pozycję, jaką chce zająć tą pracą wśród innych badaczy postzależności kultury polskiej. W tym celu śledzę historycznoliteracki porządek przyjęty przez Uffelmanna w książce, próbuję także opisać jego poszczególne części. Szczególną uwagę zwracam na pojęcia samoorientalizacji, autoindianizacji oraz autoproletaryzacji, za pośrednictwem których autor ujmuje literaturę XIX, XX i XXI wieku (m.in. Henryka Sienkiewicza czy migrantów poakcesyjnych) w dychotomię ofiara – kolonizator. Pułapki tej dychotomii i sposób jej omijania bądź zaostrzania w dyskursie akademickim polskich badaczy postzależności omawiam w ostatniej części artykułu.
Three Visions of Humanity in Extraterrestrial Ecosystems: Klein, Kosik, Skåden
Authors: Pokrywka Rafał
Published: October 2022

In the paper, three contemporary science fiction novels are compared: Die Zukunft des Mars (2013) by Georg Klein, Kameleon (2008) by Rafał Kosik, and Fugl (2019) by Sigbjørn Skåden. As possible scenarios of a future colonisation of other planets, the novels represent three different patterns of human existence in extraterrestrial ecosystems: adaptation, imitation, and indifference. They are discussed in the context of contemporary speculative narrations on human life outside of Earth.
Kulturowe aspekty dawnego dyskursu naukowego
Authors: Rejter Artur
Published: October 2022

The text presents an analysis of three Polish herbariums from the period of the sixteenth to the seventeenth centuries as examples representing the ancient academic discourse. The presented considerations allow for maintaining the claim about the cultural aspect of Polish academic discourse in the distant past. The texts which represent it are the source of the information about the state of the knowledge in chosen domains and dis- ciplines. Moreover, they constitute the reflection of the knowledge itself in its practi- cal use described in the herbariums, which is a peculiar feature of old Polish academic texts. Justified, then, is the claim that these analysed texts and their discourse are aca- deming in nature, of course on condition that one takes into account their historical context. Apart from the professional awareness of the time, one notices certain strate- gies for constructing the texts and their discourse which prove the academic discourse. Features such as precision, objectivity, argument problematisation etc. were developed and strengthened in subsequent centuries.

Systematyka operowych duchów
Authors: Golianek Ryszard Daniel
Published: October 2022

Ghosts have been an attractive element of operatic dramaturgy since the beginning of the genre’s history, and their stage presence influences the metaphysical and fantastic features of the works. In seventeenth- and eighteenth-century operas, conventional forms of musical presentation and characteristics of ghosts were developed, and in the nineteenth century a conventionalized method of musical presentation of ghosts in opera was shaped, which was also due to the great popularity of the theme of various spectres and phantoms in romantic culture. The proposed systematics concerns the ghosts presented in operatic works. Three criteria of division have been introduced: the existential status of ghosts, their number (singularity or multiplicity), and the types of afterlife the ghosts are associated with. The systematics is accompanied by the distinction of the means of musical characteristics used by opera composers in order to suggestively represent ghosts in their works.

Teatr cieni: „Wieczór w Teatrze Wielkim” Stanisława Balińskiego
Authors: Puchalska Iwona
Published: October 2022

The text is devoted to an emigration poem by Stanisław Baliński, A Night at the Grand Theatre (1943), in which the Warsaw opera became a synecdoche of the pre-war Warsaw, and the entire poetic structure is built as a kind of virtual stage on which special characters appear and perform their roles. This text is an interesting contribution to the research on the influence of the imaginarium of the musical theatre on the imagination of twentieth-century poets, and at the same time performs a specific functionalisation of the operatic character – in several meanings of the word.

Authors: Heine Carl , Durmaz Emre Can , Wang Defu , Cao Zhibo , Wietstruck Matthias , Tillack Bernd , Kissinger Dietmar
Published: October 2022

Dielectric spectroscopy in the sub-THz regime is a promising candidate for microfluidic-based analysis of biological cells and bio-molecules, since multiple vibrational and rotational transition energy levels exist in this frequency range (P. Siegel, “Terahertz technology in biology and medicine,” IEEE Trans. Microw. Theor. Tech., vol. 52, pp. 2438–2447, 2004). This article presents our recent efforts in the implementation of microfluidic channel networks with silicon-based technologies to unleash the potential of an integrated sub-THz microfluidic sensor platform. Various aspects of dielectric sensors, readout systems, flowmeter design as well as implemention- and technology-related questions are addressed. Three dielectric sensor systems are presented operating at 240 GHz realizing transmission-based, reflection-based and full two-port architectures. Furthermore different silicon based microchannel integration techniques are discussed as well as a novel copper pillar-based PCB microchannel method is proposed and successfully demonstrated.
Control of multifunctional inverter to improve power quality in grid-tied solar photo voltaic systems
Authors: Daravath Ramesh , Sandepudi Srinivasa Rao
Published: October 2022

In this paper, a control algorithm is proposed for a multifunctional inverter to improve power quality in a grid-tied solar photo voltaic (SPV) systems connected to non-linear and unbalanced loads. During light loads and low solar irradiance, the surplus capacity of inverter rating is optimally utilized to compensate some of the power quality (PQ) indices based on conservative power theory (CPT) along with active power injected into the utility grid and also connected loads. The stationary reference frame based proportional resonant (PR) current controller is designed to facilitate accurate tracking of inverter currents, fast time response under dynamic conditions when unbalanced and non-linear loads are connected at the point of common connection (PCC). The proposed control scheme enables selective compensation of power quality indices such as harmonics, unbalance and reactive powers depending on type of load and grid requirements there by, reducing the burden on the utility grid. Experimental results for various dynamic conditions are presented to validate the proposed controller performance and highlight the merits.

Authors: Li Jilin , Zhao Nana , Li Shujuan , Xu Yunhua , Liu Heguang , Shao Tiantian , Wang Xin
Published: October 2022

A TaC/Fe composite layer was prepared on a gray cast iron surface by using the interfacial reaction technique. The phase composition, microstructure and crystal structure of TaC/Fe composite layer were analyzed with X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The hardness and elastic modulus of TaC/Fe composite layer were examined by nano-indentation testing. The plastic deformation behavior of TaC/Fe composite layer was characterized with the index of creep stress. The results demonstrated that the intrinsic hardness and elastic modulus of TaC/Fe composite layer were 21 GPa and 413 GPa, respectively. During nano-indentation testing, the plastic deformation resistance of TaC/Fe composite layer decreased with the increase in load, while the plastic deformation resistance decreased as the loading rate rose.
Introducing covariances of observations in the minimum L1-norm, is it needed?
Authors: Suraci Stefano S. , Oliveira Leonardo C. , Klein Ivandro , Goldschmidt Ronaldo R.
Published: October 2022

The most common approaches for assigning weights to observations in minimum L1-norm (ML1) is to introduce weights of p or

p

\sqrt{p}

, p being the weights vector of observations given by the inverse of variances. Hence, they do not take covariances into consideration, being appropriated only to independent observations. To work around this limitation, methods for decorrelation/unit-weight reduction of observations originally developed in the context of least squares (LS) have been applied for ML1, although this adaptation still requires further investigations. In this article, we presented a deeper investigation into the mentioned adaptation and proposed the new ML1 expressions that introduce weights for both independent and correlated observations; and compared their results with the usual approaches that ignore covariances. Experiments were performed in a leveling network geometry by means of Monte Carlo simulations considering three different scenarios: independent observations, observations with “weak” correlations, and observations with “strong” correlations. The main conclusions are: (1) in ML1 adjustment of independent observations, adaptation of LS techniques introduces weights proportional to

p

\sqrt{p}

(but not p); (2) proposed formulations allowed covariances to influence parameters estimation, which is unfeasible with usual ML1 formulations; (3) introducing weighs of p provided the closest ML1 parameters estimation compared to that of LS in networks free of outliers; (4) weighs of

p

\sqrt{p}

provided the highest successful rate in outlier identification with ML1. Conclusions (3) and (4) imply that introducing covariances in ML1 may adversely affect its performance in these two practical applications.
