Research on the Survival Analysis of Chinese ST Enterprises
Authors: Tian Haonan
Published: September 2021

For a long time, some companies have basically no revenue, but have not delisted from the market with poor performance, reflecting the embarrassment of the system. One of the reasons for the difficulty of enterprise delisting is the existence of ST companies in the market, which results in the scarcity of shell resources of listed companies. How to optimize the market exit mechanism has become an urgent problem to be solved. This paper selects Chinese listed companies that were processed by ST from 1998 to 2020 as the research object, and uses survival analysis to study the survival problems of ST companies, that is, the time rule of ST companies' delisting and delisting. The results show that the probability of capping incidents of listed companies after the implementation of special treatment increases first and then decreases, reaching a peak in the second year after the implementation of ST, and a substantial decline in the third year, and it can be achieved in the sixth year and beyond. Few ST companies have decapitated; the probability of delisting events of listed companies after the implementation of special treatment also increases first and then decreases, reaching a peak in the third year after the implementation of ST. In the fifth year and beyond, few ST companies have retired. city.

Published: September 2021

A descriptive cross sectional study was conducted among single group nursing officers working in JIPMER hospital, Puducherry in morning and general shift. The result was calculated using expected proportion level of happiness from previous study which showed 28.9% of nurses having very good level of happiness. The sample size estimated using 10% precision, 5% significance level and sample size is 274, rounded of to 275. The sampling technique used was simple random sampling. The data was collected by using Oxford happiness scale questionnaire and association with demographic variables was done like- age, gender, education, years of experience, occupation, family income, marital status, and type of family. Overall it took around 15- 20 minutes only. After one week, same nursing officers were asked to assemble in a common place at the same time. The same questionnaire was given to them to assess the reliability of the tool – by test and re-test method.Descriptive statistics, mean, standard deviation and t test were used to statistically analyze the data. Mean value of happiness was 66 +_ 0.365, there was no significant correlation between happiness and socio demographic variables like- age (P=0.84), gender (P=0.26), occupation (P=0.60), education (P=0.61). However there was a significant relationship between years of experience and happiness level (P=0.047)

Clustering effects on the diffusion of patchy colloids in disordered porous media
Authors: Holovko M. F. , Korvatska M. Ya.
Published: September 2021

Enskog theory is extended for the description of the self-diffusion coefficient of patchy colloidal fluid in disordered porous media. The theory includes the contact values of fluid-fluid and fluid-matrix pair distribution functions that are modified to include the dependence from the so-called probe particle porosity, φ, in order to correctly describe the effects of trapping the fluid particles by a matrix. The proposed expressions for the modified contact values of fluid-fluid and fluid-matrix pair distribution functions include three terms. Namely, a hard sphere contribution obtained by us in the previous work [Holovko M. F., Korvatska M. Ya., Condens. Matter Phys., 2020, 23, 23605], the depletion contribution connected with the cluster-cluster and cluster-matrix repulsion and the intramolecular correlation inside the cluster. It is shown that the last term leads to a remarkable decrease of the self-diffusion coefficient at a low fluid density. With a decreasing matrix porosity, this effect becomes weaker. For intermediate fluid densities, the depletion contribution leads to an increase of the self-diffusion coefficient in comparison with the hard sphere fluid. For a sufficiently dense fluid, the self-diffusion coefficient strongly decreases due to a hard sphere effect. The influence of the cluster size and the type of clusters as well as of the parameters of porous media is investigated and discussed in detail.
An Optimized Micropropagation Protocol by Ex Vitro Rooting of Pear Rootstock OHF 333 (Pyrus communis L.)
Authors: Dimitrova Nataliya , Nacheva Lilyana
Published: September 2021

Pear rootstock OHF 333 (Pyrus communisL.), which is included in the US ‘Old Home’ × ‘Farmingdale’ series, is characterized by good compatibility with most other varieties, high yields, and a moderate degree of resistance to fire blight. Micropropagation in vitro has shown promise for rapid, large-scale cloning of disease-free plant material throughout the year. However, pear shoots are often recalcitrant to rooting, and this process is highly genotype-dependent. This study aimed to improve the micropropagation protocol by ex vitro rooting of pear rootstock OHF 333 (Pyrus communisL. ‘Old Home’ × ‘Farmingdale’). Charkor, a new plant growth regulator of natural origin was used, which contains metabolism products of symbiotic fungus-endophytes of ginseng roots, as an alternative to synthetically produced plant growth regulators (PGRs). Microcuttings were obtained from in vitro cultured shoots and subjected to four different treatments for ex vitro rooting: 1 g L−11-naphthaleneacetic acid (NAA) (as a powder), 0.5 mL L−1Charkor for 3 hr or 6 hr, or the same concentration of Charkor prepared as a powder. Microshoots dipped in sterile distilled water with no additional hormonal treatments served as controls. Cultures were kept in a growth chamber under a 16-hr photoperiod, with air humidity maintained close to 100% (above 96%) for 2 weeks and then gradually reduced to 60%. Data on final acclimatization rate (survival rate; %), mean number of roots per plant, stem and root length, mean number of leaves per plant, and final acclimatization rate were collected 90 days after transplanting to ex vitro conditions. All treatments induced a successful acclimatization rate of more than 31%. The highest survival rate (86%) and longest stems were achieved by treatment with 0.5 mL L−1Charkor for 6 hr. The greatest mean number of roots per plant, root length, and number of leaves was achieved in the variant treated with 1 g L−1powdered NAA.
ТЕМПЕРАТУРНИЙ ВПЛИВ ЛАНДШАФТНИХ ПОЖЕЖ НА ЕКОЛОГІЧНИЙ СТАН ЕДАФОТОПУ
Authors: Popovych Vasyl , Hapalo Andriy
Published: September 2021

В Україні лісові пожежі набувають значних обсягів та перетворюються на надзвичай-
ні ситуації загальнодержавного значення. Внаслідок локалізації та ліквідації великих
і особливо великих лісових пожеж, пожеж у природних екосистемах, залучається
значна кількість особового складу та техніки. Знищуються практично усі компоненти
довкілля – флора, фауна, ґрунти, забруднюються річки, водойми, повітря. Пожежі у
природних екосистемах спричиняють потрапляння в атмосферу значної кількості
летких продуктів горіння та небезпечних речовин і сполук.
Метою роботи є висвітлення результатів досліджень моніторингу довготривалого
впливу лісових пожеж на один із найважливіших компонентів екосистеми – едафотоп.
Для досягнення поставленої мети були сформовані такі основні завдання: провести
аналіз наукових та літературних джерел щодо проблематики впливу лісових пожеж
на едафотоп у вітчизняному та зарубіжному контекстах; дослідити модельне вогнище
стосовно температурного та вологісного режимів; встановити температуру полум’я
на різних ділянках модельного вогнища; встановити потужність еквівалентної дози
фотонного іонізуючого випромінювання на місці проведення експерименту.
Теплові режими Малого Полісся є достатніми для розвитку багатьох рослин. Веге-
таційний період триває понад 200 днів, а період з активними температурами (понад +
10°С) – 150–160 днів. Більше 100 днів у році мають середньодобову температуру понад
+ 15°С (період інтенсивної вегетації). Відлиги, які понижують морозостійкість лісових
та сільськогосподарських культур, затяжні весни у зв’язку з повільним таненням снігу
гальмують швидкий прихід тепла.
Експериментальні дослідження з вивчення впливу ландшафтних пожеж на екологіч-
ний стан едафотопу здійснювалися на території Малого Полісся поблизу Рава-Руського
лісництва в селі Лавриків Жовківського району Львівської області. Відбір проб ґрунтів
для досліджень їхнього екологічного стану здійснювався із врахуванням давності (за роками) горіння рослинності та лісової підстилки. Також було створено штучне
модельне вогнище ландшафтної пожежі (низової, лісової) на відкритому просторі з
дотриманням усіх вимог Правил пожежної безпеки в лісах України з метою фіксування
температури та вологості ґрунту в зоні горіння, а також аналізу відібраних ґрунтових
проб із ділянок горіння.
Встановлено, що температура полум’я під час горіння лучної рослинності в початковий
момент часу становила +66,7°С. У процесі горіння, через 20 секунд, температура полум’я
сягнула +352,5°С, максимальною температура полум’я була +715,7°С після вигорання
всього горючого матеріалу (через 2,5 хв після початку досліду). Водночас, на глибині
5 см у початкових точках горіння температура едафотопу підвищується із +7°С до +20 ±
24°С. Яскраво вираженого діапазону зміни вологості на глибині 5 см не спостерігалося.
Отримані результати є важливими з точки зору вивчення впливу підвищених температур
на компоненти біосфери, а також відновлення девастованих територій.
Estoński CIT 2.0, czyli drugi krok w kierunku pełnego
systemu estońskiego w Polsce
Authors: Sarnowski Jan , Łożykowski Aleksandrer
Published: September 2021

Estoński CIT to alternatywna forma opodatkowania dochodu, dostępna dla podatników podatku dochodowego od
osób prawnych. Opodatkowanie następuje jedynie w momencie wypłaty podzielonego zysku. Zasada ta wspiera
inwestycje, płynność i produktywność firm. W 2021 r. z ryczałtu od dochodów spółek kapitałowych skorzystała
jednak jedynie część firm, którym ten rodzaj opodatkowania się opłacał. Wśród przyczyn tego stanu rzeczy można
wskazać pesymizm dotyczący oczekiwanych wyników finansowych w 2021 r., oczekiwanie na ukształtowanie się
stabilnej praktyki interpretacyjnej nowych przepisów, funkcjonowanie alternatywnego rozwiązania w postaci rezerwy
inwestycyjnej, ryzyka związane z planowaniem zwiększenia nakładów inwestycyjnych czy też koszty transferu
między ogólnymi zasadami opodatkowania a estońskim CIT. Istotne zmiany w zakresie funkcjonowania estońskiego
CIT przewiduje ustawa wdrażająca podatkowe aspekty Polskiego Ładu1. Zlikwidowane będą najważniejsze bariery
wejścia w to rozwiązanie. Symulacje obciążeń wskazują, że po reformie w ramach Polskiego Ładu estoński CIT zyska
znacząco na atrakcyjności względem klasycznych reguł rozliczenia podatku dochodowego od osób prawnych.
Gender Disparities in Bladder Cancer
Authors: Zhang Yingsheng , Theodorescu Dan , Li Xue
Published: September 2021

Biological sex is an independent risk factor of cancer. Men are three to five times more likely than women to develop bladder cancer even when known risk factors are taken into consideration. Development of sex in mammals is often viewed as a two-step process. The first step is sex determination, of which the XX and XY sex chromosome complements trigger gonad differentiation to form the ovary and testis, respectively. After that, sex hormones secreted by gonads initiate sexually dimorphic differentiation of nongonadal tissues. However, this model has been challenged by recent findings revealing an independent contribution of sex chromosomes to sexual dimorphism. In this chapter, we discuss how the sex chromosomes and sex hormones together cause gender disparities in bladder cancer. We propose a concept of epigenetic sex – epigenetic differences between males and females – and suggest that the sex epigenome is a previously unknown biasing factor contributing to gender disparities in bladder cancer.
Seasonal Variations of Densities of Biomphalaria pfeifferi, the Intermediate Host of Schistosoma mansoni Parasite at the North of Senegal

Published: September 2021

Schistosomiasis is becoming more persistent because of the widespread distribution of intermediate host snails in several regions of Africa, including Senegal. The intermediate snail host of the human intestinal schistosome is Biomphalaria pfeifferi and is permanently present in northern Senegal because of the presence of the abundant freshwater habitat throughout the year. Here, we observed the seasonal variation in B. pfeifferi abundance in the Saint-louis region at the North of Senegal in West Africa. We performed snail and environmental parameter sampling across two different seasons described for Senegal: a dry season that runs roughly from mid-October to mid-June and a rainy season that spans approximately from late June to early October. We also split the dry season into two categories representing periods of time when water temperatures were either decreasing (dry1) or increasing (dry2). We used regression analyses to model snail density across the seasons and investigated which environmental variables influenced snail abundance. Results suggested that snails were more abundant and peaked during the rainy season, which lowest abundances during the dry season when temperatures were declining. The above seasonal variations of snail density were positively linked to the environmental drivers including periphyton (food resource for snails), aquatic vegetation abundance, water temperature and dissolved oxygen and negatively to both pH and water conductivity. Our findings may be useful for snail control efforts by targeting specific periods and/or site conditions when snail abundances are greatest.
Redescobrir a Saúde que Nunca se Perdeu
Authors: Borges Paulo ,   Philosophy Documentation Center
Published: September 2021

We present the Buddhist view of the origin of disease and suffering in the ignorance of the basic health or sanity of being and awareness, as well as the way to recognize and reintegrate it, which is the healing process. We question what is commonly thought about the place of suffering in Buddhism, based on the aspects of the Buddhist view and experience that most contrast with the dominant perception of what reality and human life are. It’s only by not camouflaging them that one can understand the specificity of the Buddha’s path and the proposals for healing and transcending disease and suffering it offers.
Dobradiças, Vertigem Epistémica e Moralidade
Authors: Venturinha Nuno ,   Philosophy Documentation Center
Published: September 2021

This paper explores central themes of Duncan Pritchard’s epistemology intimately related to the Wittgensteinian idea of a “hinge epistemology”. The first section calls attention to the eminently empirical character of our “hinges”. The second section focuses on Pritchard’s notion of “arational hinge commitments”, more specifically his distinction between the pair “über hinge commitments”/“über hinge propositions” and the pair “personal hinge commitments”/“personal hinge propositions”. The third section brings to the discussion Timothy Williamson’s view of “inexact knowledge” and examines another pair of notions introduced by Pritchard, namely “antiskeptical hinge commitments”/“antiskeptical hinge propositions”. I conclude with a reevaluation of the diagnosis made by Pritchard that, confronted with a sceptical scenario, our “epistemic angst” can be surpassed if we follow Wittgenstein’s teaching in On Certainty about the “structure of rational evaluation”, but that an “epistemic vertigo” can never be ultimately dispelled. My argument is that in a moral scenario there is no room for vertigo.
Political Acts and Terrorism

Recent work in the ethics of care is used as a point of departure for thought about the kinds of social conditions that lead to terrorism. Allusion is made to the work of Bayoumi, Held and others, and it is concluded that political acts of terror are often a response to a climate of hostility, including microaggression.
Marx, Hegel and the Orient
Authors: Conversano Emanuela ,   Philosophy Documentation Center
Published: September 2021

My article does not aim at a comparison between Hegel’s and Marx’s points of view on Asia as such. The Hegelian motives are employed to understand the place and the significance of the Orient in Marx’s writings from the 1850s onwards. The more Marx learns from original and/or updated sources on the Oriental societies, the more Hegel’s authority seems inadequate to provide a reliable and comprehensive account of their history and social organization. Yet his “spirit” still holds together the different perspectives from which the subject is approached by Marx (economy, history and praxis, above all). In other words, Marx’s interest in Asia is here considered through the lens of Hegel’s legacy in order to reflect on the endless effort of the materialistic dialectic to encompass the complexity of reality and global history.
Repetition: Thinking Between G.W. F. Hegel’s Philosophy of History (1837) and Karl Marx’s The Eighteenth Brumaire of Louis Bonaparte (1852)
Authors: Balasopoulos Antonis ,   Philosophy Documentation Center
Published: September 2021

Taking its cue from the untimely paradoxes manifesting themselves in some of the most visible instances of Hegel’s and Marx’s reception in the twentieth century, this essay proceeds to explore the ground between the two thinkers with particular reference to their philosophico-historical grasp of repetition. After a number of preliminary observations on the ideological subtext involved in Marx’s reference to Hegel in the Eighteenth Brumaire of Louis Bonaparte and the temporality their intertextual conjuncture stages, I focus on four major complications that attend the comparison of Hegelian and Marxian notions of repetition, as well as on their correlation to the historical events of Revolution, Counter-Revolution and Restoration. I conclude with some reflections on the “exit strategies” Marx and Hegel adopt vis-à-vis the specter of iteration as a sign of submission to the gravitational pull of the past upon the present and future.
Do Mundo Pedagógico-Filosófico em Wittgenstein
Authors: Barra Bárbara Wilson ,   Philosophy Documentation Center
Published: September 2021

This dissertation aims to understand, in the light of Wittgenstein’s Investigations, language as a match or a game, whose performance is trained by using certain rules, taking in traditions and those techniques that propel the young shoots to the integration in the world. In order to this, it will be developed the argument that sustains that the learning process, which is incompatible with an automatic system of direct and instantaneous print of information – considering that there is no way that children resemble programmable automata, such as the film Kynodontas simulates –, should go hand in hand with the manner of doing philosophy, given its irreplaceable role in the formation and development, on the one hand, of perspicuity and elucidation, on the other, of thinking, imagination and personality of children. At this point, it must be clear that what is up to educators and tutors is nothing more than introduce the world to the young shoots as it is seen and conceived, through what is known and actually it is, but mainly to invite them to participate in it.

Authors: Rodriguez Huaman Yda , Contreras Pavel J , Lozada-Urbano Michelle
Published: September 2021

Objective To describe the clinical characteristics and sociodemographic factors associated with COVID-19 among pregnant women in a maternal and children's hospital in Lima, Peru. Methods Quantitative observational study. The population under study consisted of pregnant women who attended an emergency room and had a COVID-19 test. These women were assessed for age, gestational age, place of origin, occupation, education, marital status, number of children, previous body mass index, gestational body mass index, tetanus vaccination, prenatal controls, and hemoglobin. After bivariate analysis, a generalized linear regression model was applied. Results We included 200 women aged between 18 and 34 years (84.5%) with a median gestational age of 36 weeks. More than half were from Lima (52.5%), most were housewives (79%), had high school education (71.9%), and had a cohabiting marital status (60%). The COVID-19 test positivity was 31.5% by rapid tests. Pregestational body mass index assessment showed that 36.7% of normal weight, 38,1% of overweight, and 30.3% of obese pregnant women had COVID-19 infection. 39.7% of patients with hemoglobin levels greater than or equal to 11 g/dL, 21.2% of patients with values between 10 and 10.9 g/dL, and 20% of patients with values between 7 and 9.9 g/dL had COVID-19 infection. The prevalence ratio (with a 95% confidence interval) found that cohabitation was associated with a lower risk of having COVID-19 infection in pregnant women (prevalence ratio: 0.41, p < 0.001). Conclusion Cohabiting pregnant women had a lower risk of COVID-19 infection compared with other marital statuses. Further research is needed to evaluate COVID-19 associated factors in pregnant women and possible sociodemographic or economic factors behind cohabiting marital status association among this population.

A fauna edáfica é usada como bioindicador de qualidade do solo, pois é capaz de transformar o solo, sendo, altamente sensível às modificações ambientais. Possui uma diversidade de invertebrados que vive permanentemente ou que apresenta um ou mais ciclos de vida no solo que variam muito em tamanho e diâmetro, o que lhes concede habilidades nos métodos de alimentação e adaptação ao hábitat. Assim, objetivou-se identificar e classificar os diferentes grupos da macro e mesofauna do solo, estudar sua abundância e diversidade em dois períodos do ano, em um fragmento de caatinga em Redenção, Ceará. O estudo foi realizado na Fazenda Experimental (FEP) da Universidade da Integração Internacional da Lusofonia Afro-Brasileira (UNILAB), onde foram instaladas 72 armadilhas para coleta da macro e mesofauna nos períodos seco (2015) e chuvoso (2016). Os organismos capturados foram triados, contados, identificados e classificados em grandes grupos. Foram calculados: densidade e riqueza de grupos e índices de diversidade e uniformidade do solo. Registrou-se 23515 e 18962 indivíduos nos períodos seco e úmido, respectivamente. A riqueza total foi de 43 grupos no período seco e 41 no período chuvoso. Os grupos mais representativos (97%) pertencem a 12 ordens, distribuídas em quatro classes, sendo Entomobryomorpha, Hymenoptera (Formicidae), Diptera, Acarina, coleoptera e poduromorfa, as mais abundantes. A sazonalidade não alterou composição da fauna edáfica, porém o período chuvoso favoreceu maior diversidade e equabilidade entre os grupos da pedofauna identificados.

O estudo teve como objetivo avaliar as características morfométricas do pintado criado no Pantanal de Mato Grosso do Sul (Brasil), em diferentes classes de peso, oriundos de dois sistemas de criação (viveiros escavados e recirculação). Os peixes obtidos em viveiros escavados foram adquiridos com um piscicultor, sendo utilizados 35 exemplares, distribuídos em um delineamento inteiramente casualizado, composto por cinco tratamentos (diferentes classes de peso: 1) 700 a 899 gramas (g), 2) 900 a 1099g, 3) 1100 a 1299g, 4)1300 a 1499g e 5)1500 a 1699g.) e sete repetições. Os peixes do sistema de recirculação de água foram criados em um tanque de geomembrana de 30 m3 com 100 animais e, após um período de 195 dias, 35 peixes foram classificados nas mesmas classes de peso descritas anteriormente. Comparando as relações morfométricas dos peixes criados nos viveiros e as do sistema de recirculação não apresentam diferenças significativas (p>0,05). Portanto, os pintados criados nos dois sistemas apresentam as mesmas características morfométricas com comportamento linear de crescimento e relações morfométricas similares com uma tendência de estabilização da altura do corpo com a elevação do peso.

Ultimamente, as questões ambientais estão mais presentes nos meios de comunicação, tendo em vista a relação da sociedade com o uso predatório dos recursos naturais. Persiste, ao que parece, a sensação de que os recursos naturais são infinitos. Considerando que os adolescentes se tornarão brevemente consumidores mais ativos, influenciando o sistema produtivo, entende-se pertinente conhecer o seu comportamento quanto aos hábitos de consumo. O objetivo do estudo é descrever a percepção e os hábitos de consumo de 109 estudantes de Ensino Médio de 4 cursos de uma unidade do IFPI. Metodologicamente, a pesquisa tem abordagem quantitativa, natureza descritiva-exploratória, com uso do método survey e utilização de questionário estruturado em entrevistas presenciais. Como resultado, foi possível identificar os aspectos socioeconômicos, os graus de percepção ambiental e de consumo consciente dos respondentes. Com o uso do VAPERCOM, notou-se que os estudantes possuem percepção ambiental, e potencial possibilidade de se tornarem consumidores conscientes.
Percepção do risco a deslizamentos em áreas vulneráveis na Serra Do Bodopitá, Queimadas/PB
Authors: Araújo Helena Maria da Conceição de , Xavier Rafael Albuquerque
Published: September 2021

Os riscos ambientais associados a deslizamentos crescem em intensidade e a percepção a estes encontra-se num nível de crescimento inversamente proporcional, agravando os fenômenos e expondo os agentes a consequências sociais, econômicas e ambientais alarmantes. Sendo assim, a prevenção é a melhor forma de mensurar o problema e evitar novos desastres, contudo, quando é irremediável, a gestão dos riscos configura-se como uma necessidade. A presente pesquisa objetivou avaliar a percepção da população que reside no município de Queimadas/PB, situado nas encostas da Serra de Bodopitá, frente ao risco geológico-geomorfológico de ocorrência de rolamento de blocos; através da pesquisa de natureza exploratória, com visita de campo. A Geografia do risco vem auxiliar na analise através do conceito de paisagem – percepção do espaço vivido em sua forma, funcionalidade, estrutura e processo – e o lugar com o sentimento de pertencimento que geralmente posiciona a população residente na naturalização do risco evidente. Constata-se que os fatores como: casa própria, proximidade a familia e emprego são as principais variaveis que possibilitam a neutralização da percepição ao risco, pois a sociedade sabe dos risco e do quão pode ser prejuducial, mas os desconsideram.
Specialestuderendes læringsudfordringer i vejledningen - nudging som handlemulighed
Authors: Jensen Hanne Nexø , Jensen Christina Juul
Published: September 2021

Specialeskrivere møder læringsudfordringer i skriveprocessen. Hvilke læringsudfordringer, det er, og hvordan studerende og vejledere hånd-terer dem, er artiklens fokus. Empirien er videooptagede vejlednings-møder, hvor der er minimum to optagelser for hver vejleder og stude-rendes forløb. Det teoretiske afsæt er generiske læringsudfordringer i vejledningsprocesser, hvor læring opstår, når de studerende passerer en læringsudfordring. Vejledere kan bruge forståelsen af læringsudfor-dringer til at ”nudge”- plante en idé – som en måde at få studerende til at passere læringsudfordringerne. MA students writing up their final theses encounter a variety of conceptual thresholds during the process. The focus of this article is the identification of different kinds of conceptual threshold, and how the students overcome these obstacles. Video recordings of student supervision meetings provide the data for the analysis. For each supervisor – supervisee at least two recordings are considered. We go on to discuss how supervisors can make use of a conceptual thresholds approach, and nudge students in ways that will help them move on more easily.
Informationskompetence, en opgave for bibliotek og uddannelse i fællesskab
Authors: Bønløkke Mette , Kobow Else , Kristensen Anne-Kirstine
Published: September 2021

Erfaringer og undersøgelser om samarbejde mellem uddannelser og forskningsbiblioteker viser, at ikke alle har en curriculumintegreret indsats og et formaliseret samarbejde om undervisning og vejledning til støtte for udvikling af de studerendes informationskompetence. Et aktionsforskningsprojekt undersøgte, hvad der havde betydning i etablering af et formelt samarbejde mellem bibliotek og uddannelse. I projektet deltog tre bibliotekarer, seks undervisere og en biblioteksleder samt to uddannelsesledere og to projektledere fra VIA University College. Fokusgruppeinterviews, projektprotokoller, referater fra refleksions- og støttemøder samt mailkorrespondance udgjorde data, som blev kvalitativt analyseret. Resultaterne viste, at følgende områder er betydningsfulde: ledelsesstøtte, en anerkendende tilgang, oplevelse af nødvendighed og ejerskab til processen, fælles fokus og mål tilpasset den enkelte uddannelses behov, rammer og ressourcer, faglig støtte og erfaringsudveksling i processen.

Research on and experiences from cooperation between faculty libraries and faculties indicate that not all programmes have integrated information literacy in curriculum or have a formalised cooperation between library and faculty on information literacy. Using action research we explored issues at stake when cooperation between library and faculty is initiated. Participants were 3 librarians, 6 educators, 1 library manager, 2 directors of programme and 2 project managers from VIA University College. Data derived from focus group interviews, process protocols, records of reflective sessions and support meetings and mail correspondence was qualitatively analysed. The results showed that the following areas seemed important: Support from the management, an appreciative approach, a need for change, ownership of the process, common focus and goals according to the need of the programme, a set frame work and resources, professional support and sharing of experiences in the process.
Situationspraktik – mellem universitet og praksis
Authors: Skøtt Bo , Troelsen Rie
Published: September 2021

Denne artikel omhandler et forsøg med integration af praksis i undervisningen, som har til formål, 1) at give de studerende en fornemmelse for, hvordan fagene på uddannelsen har relevans for arbejdet i praksis, og 2) at kvalificere de studerende til mødet med praksis. Derfor inddrages især Etienne Wenger og Jean Laves teorier om ’praksisfællesskaber’ med fokus på ’situeret læring’ i overvejelserne over og planlægning af forsøget. Forsøget betegnes Situationspraktik og organiseres ud fra tre overordnede aktiviteter: asynkrone studieaktiviteter (litteraturstudier, planlægning og forberedelse af delarrangementer), klassisk konfrontationsundervisning (teori- analyse og metodepræsentation) og som et arrangement, hvor resultaterne af disse aktiviteter omsættes i praksis. I forsøget deltager 12 studerende, der alle går på 4. semester.

Situationspraktikken resulterer for underviser i erfaringer med, hvilke pædagogiske muligheder og udfordringer der er med at facilitere læringsfællesskaber de studerende imellem og med inddragelse af eksterne stakeholders.

This article sets out to describe an attempt to increase students’ understanding of professional practice. 'Situational internship', as the activity is termed, aims to provide students with experience of practice in their chosen field as part of their qualification. Etienne Wenger and Jean Laves’ theories on 'communities of practice' and 'situated learning' are used when considering and planning suitable learning activities.

The study is organized as three main activities: asynchronic student activities (literature studies, planning and preparation of sub arrangements), teacher initiated activities (introduction of theories, analysis and methods) and the implementation of an event.

Situational internship provides many interesting experiences, both for students and teacher, especially the opportunities and challenges of creating a learning community between students and teachers, and also between students and external stakeholders. The ambition to change the students' preconceptions of practice, and the teacher in the role of facilitator are thematized in the article.
Samhørighed, interaktion og vidensdeling blandt studerende - erfaringer fra et IKT-pædagogisk udviklingsprojekt
Authors: Davidsen Jacob , Ryberg Thomas
Published: September 2021

I artiklen beskriver vi erfaringer fra et projekt på Aalborg Universitet (AAU), hvor forfatterne designede et forløb med Google+ communities for at skabe øget samhørighed, interaktion og vidensdeling mellem studerende på 1. semester på studiet Kommunikation og Digitale Medier (KDM). Studier viser, at studerende i vid udstrækning anvender sociale netværkssteder, såsom Facebook, i forbindelse med deres studieliv til faglige, men i særdeleshed sociale aktiviteter. Det betyder, at vi som undervisere har et begrænset indblik i, hvad de studerende kommunikerer om og har af problemstillinger i deres studieliv, hvilket er problematisk i forhold til at udvikle et fagligt fællesskab og forankringspunkt. Det skyldes endvidere, at brugen af det institutionelle system Moodle er begrænset til envejskommunikation fra underviser til studerende. Formålet med udviklingsprojektet var således at skabe et tredje rum imellem Facebook og Moodle, som skulle give de studerende oplevelser og erfaringer med, hvordan de kan bruge og finde inspiration i hinandens arbejde ved at deltage i et online-fællesskab sammen med underviserne. Projektet viser, at underviserne spiller en central rolle i udviklingen af online-fællesskabet, men samtidig, at nogle af forløbets aktiviteter har haft positiv indflydelse på de studerendes samhørighed, interaktion og vidensdeling gennem forløbet.

In this paper, we share experiences from a project at Aalborg University (AAU), in which the authors designed a course using Google + Communities for the first semester of the Communication and Digital Media programme. In this programme Google + Communities was used to nurture both an academic and social community among the students, through encouraging interaction and knowledge sharing. Studies show that students prefer to use Facebook for academic and social purposes. As a consequence, teachers have minimal insight into the challenges facing students, which is problematic when trying to create and support an academic community. Moreover, it is problematic that the institutional system Moodle primarily is used by the teachers to push information in the direction of the students. Thus, we wanted to design a third space that would fit in-between Facebook and Moodle, and which would allow the students to experience the benefits of participating in an online community with fellow students and teachers. The project shows that teachers are crucial in developing and maintaining the online community. But there was also evidence that some of the online activities encouraged students to interact and share knowledge and fostered a sense of community.
Hvordan begrunder undervisere deres praksis? Et interviewstudie med undervisere fra to fagmiljøer
Authors: Bager-Elsborg Anna
Published: September 2021

Formålet med denne artikel er at belyse de rationaler og begrundelser, der farver universitetsunderviseres valg af undervisningsmetoder. Med afsæt i blandt andet social praksisteori undersøges begrundelser for undervisning i interview foretaget med 17 undervisere i to forskellige fagmiljøer på et dansk universitet. Forfatteren finder, at der på trods af ligheder i metoder er meget stor forskel på de begrundelser og værdier, der ligger til grund for undervisningen, og at disse begrundelser og værdier er hentet i fagdisciplinerne.
Peer review i et obligatorisk bachelorkursus for civilingeniørstuderende i medikoteknik
Authors: Wilhjelm Jens E. , Prag Sidsel-Marie Winther
Published: September 2021

Et nyudviklet peer review-system, der integrerer studenterdata, administration og grafiske procesoversigter, blev afprøvet i et obligatorisk bachelorkursus. Overens-stemmelse mellem de studerende og hjælpelærernes kvantitative bedømmelser blev undersøgt for en relativt udfordrende opgave med 15 delspørgsmål. 49 stude-rende afleverede besvarelser. Efterfølgende blev hver besvarelse bedømt af tre medstuderende, svarende til at 735 delbesvarelser blev bedømt. Ud af disse var der enighed mellem studenterbedømmerne og hjælpelærerne i 480 tilfælde (65 %). I under 3,5 % af tilfældene var der total uenighed. Der var tendens til, at jo mere rig-tigt en besvarelse blev bedømt, eller jo mere konkret svaret var, des mere enighed. En interviewundersøgelse hos de studerende viste stor opbakning til fremgangsmå-den og viste også, at de studerende fandt det meget nyttigt at se andre studerendes besvarelser såvel som rettevejledningen. Afslutningsvis gives en række anbefalinger til processen og systemet.
Teaching ethical participatory codesign
Authors: Dupret Katia , Chimirri Niklas
Published: September 2021

How to incorporate critical and societally relevant thinking and acting into Higher Education teaching formats? The article proposes social design workshops, which teach ethics through design by explicitly addressing and building on the functional diversity of participating stakeholders, and by fostering ongoing mutual reflection. These workshops are inspired by participatory design, political theory, disability studies and psychological practice research. By drawing on empirical material from a design workshop with Bachelor students and external collaborators including psychologically vulnerable stakeholders, we argue for an adaptive framework of analytical-pedagogical inquiry that can be continuously co-designed. In particular, ethical design requires a broad and emergent definition of participation. Ethical design is participatory-democratic co-design, which acknowledges and bridges across the various stakeholders’ functional diversity.
Når forberedelse er en pligt, og undervisningen er et privilegium: et casestudie af universitetsstuderendes forberedelsespraksis
Authors: Herrmann Kim Jesper , Bager-Elsborg Anna
Published: September 2021

Kvantitative tværsnitsundersøgelser har de senere år kortlagt omfanget af danske universitetsstuderendes forberedelse, hvorimod der kun i beskedent omfang er for-sket i, hvorfor og under hvilke omstændigheder studerende forbereder sig lidt eller meget. Med afsæt i praksisteori analyserede vi gruppeinterview med studerende fra et bachelorfag, hvor studerende kun kunne møde op til undervisningen, hvis de var forberedte (forberedelsespligt). Analysen viste, at de studerende var imod forbere-delsespligt generelt, men til gengæld accepterede forberedelsespligten i det pågæl-dende fag. Derfor analyseredes de omstændigheder, under hvilken de studerende accepterede forberedelsespligten. Studiet bidrager til den eksisterende viden om universitetsstuderendes forberedelse ved at undersøge forberedelse som en praksis, som ikke alene vedrører individuelle studerendes adfærd, men ligeledes omhandler uudtalte normer, undervisningens organisering og karakteren af relationerne stude-rende og underviser imellem. Studiet peger på, at forberedelsespligt ikke nødven-digvis står i modsætningsforhold til universitetets kerneværdier, men tværtimod kan komplementere værdier som frihed, mulighed og selvstændighed.
Udvikling af studerendes selvstændighed: Stilladsering i bachelorvejledning
Authors: Simonsen Kristina Bakkær , Wichmann-Hansen Gitte
Published: September 2021

I denne artikel undersøger vi hvordan studerendes selvstændighed kan opøves i forbindelse med opgaveskrivning. Vi tager afsæt i en teoretisk skelnen mellem selvstændighed i processen og i produktet og argumenterer for, at sidstnævnte kan og bør trænes undervejs i et opgaveforløb, så de studerende gradvist opnår øget sikkerhed i videnskabelige formidling. Datagrundlaget er en empirisk case, der indeholder dels en redegørelse for et konkret bacheloropgaveforløb på en samfundsvidenskabelig uddannelse, dels en analyse af forløbets resultater i form af skriftlige evalueringsdata, karakterdata og vejlederens egne observationer. Analysen viser, at vejledere kan fremme progression i studerendes selvstændighed gennem stilladsering, dvs. ved tidligt, gradvist og systematisk at indarbejde forskellige støttende aktiviteter som skriveøvelser, peer-feedback og kollektiv vejledning. Samlet skærper aktiviteterne de studerendes blik på videnskabelige genrekrav og afmonterer dermed meget af den usikkerhed, som de kan have omkring produktkravene til en selvstændig opgave. Resultatet er større mod på opgaveprocessen og højere kvalitet i de endelige produkter.
