Origin of the residual line width under frequency-switched Lee–Goldburg decoupling in MAS solid-state NMR
Authors: Hellwagner Johannes , Grunwald Liam , Ochsner Manuel , Zindel Daniel , Meier Beat H. , Ernst Matthias
Published: February 2020

Abstract. Homonuclear decoupling sequences in solid-state nuclear magnetic resonance (NMR) under
magic-angle spinning (MAS) show experimentally significantly larger residual
line width than expected from Floquet theory to second order. We present an
in-depth theoretical and experimental analysis of the origin of the residual
line width under decoupling
based on frequency-switched Lee–Goldburg (FSLG) sequences. We analyze the effect of experimental pulse-shape errors (e.g., pulse
transients and B1-field inhomogeneities) and use a Floquet-theory-based
description of higher-order error terms that arise from the interference
between the MAS rotation and the pulse sequence. It is shown that the
magnitude of the third-order auto term of a single homo- or heteronuclear
coupled spin pair is important and leads to significant line broadening
under FSLG decoupling. Furthermore, we show the dependence of these
third-order error terms on the angle of the effective field with the
B0 field. An analysis of second-order cross terms is presented that
shows that the influence of three-spin terms is small since they are
averaged by the pulse sequence. The importance of the inhomogeneity of the radio-frequency (rf) field
is discussed and shown to be the main source of residual line broadening
while pulse transients do not seem to play an important role.
Experimentally, the influence of the combination of these error terms is
shown by using restricted samples and pulse-transient compensation. The
results show that all terms are additive but the major contribution to the
residual line width comes from the rf-field inhomogeneity for the standard
implementation of FSLG sequences, which is significant even for samples with
a restricted volume.
Parameter sensitivity analysis of dynamic ice sheet models – numerical computations
Authors: Cheng Gong , Lötstedt Per
Published: February 2020

Abstract. The friction coefficient and the base topography of a stationary and a dynamic ice sheet are perturbed in two models for the ice: the full Stokes equations and the shallow shelf approximation. The sensitivity to the perturbations of the velocity and the height at the surface is quantified by solving the adjoint equations of the stress and the height equations providing weights for the perturbed data. The adjoint equations are solved numerically and the sensitivity is computed in several examples in two dimensions. A transfer matrix couples the perturbations at the base with the perturbations at the top. Comparisons are made with analytical solutions to simplified problems. The sensitivity to perturbations depends on their wavelengths and the distance to the grounding line. A perturbation in the topography has a direct effect at the ice surface above it, while a change in the friction coefficient is less visible there.

Linguistic Politeness and Gender: Apology Strategies: A Sociolinguistic Research
Authors: Mohammad Alahmad Tarek Hider , Abdullah Alkasassbeh Asma Khaled
Published: February 2020

This paper addresses Geoffrey Leech's (2014) three semantic classifications of apology on The Portrait of a Lady which was written by Henry James. The researchers apparently address Leech’s three semantic classifications and also there are two charts and a statistic table in order to be scientific while answering the preceding assumption about gender differences in apology strategies. Apology strategies sound well-known in Anglophone. In the literature of gender, this paper targets the linguistic politeness and gender to give the readers extra vision by studying the fiction. Moreover, the researchers' purpose in this paper is to address the stereotypical assumption that women used to be politer than men. In order to find out whether these differences in number of utterances by the two groups are statistically significant or not, the researchers have used some statistical tools, namely a (T-test). An analysis of the linguistic politeness and gender can help to deep insight into each character’s personae and experiences in the fiction as well as appreciate the special gist of the fiction as well.
Raphael's Homeric and Biblical Metamorphosis
Authors: Adkins David
Published: February 2020

Why does Raphael metamorphose in his descent to Eden, and why does Milton initially disguise the metamorphosis as a simile? Though the episode is traditionally considered more Virgilian than Homeric, it is its Homeric dimension that answers these questions. Milton intervenes, I suggest, in the ancient debate on whether Hermes transforms into or merely descends like a gull. But by suggesting and then correcting the simile-reading, Milton also instructs his readers not to read the Bible's metamorphoses like Calvin, whose hermeneutics often resemble those of pagan grammarians, particularly those who read Hermes's likeness to the bird figuratively. By exploring the debates on two descents, that of Hermes and that of the Holy Spirit in the Gospels, I demonstrate how Milton employs Homeric imitation to contest Calvin's theory of accommodation and to present history as more marvelous than myth.
Milton's Chivalric Tragedy: The Persistence of Romance in Book 9 of Paradise Lost
Authors: Cook Trevor
Published: February 2020

Milton's most consequential statement regarding his plans for an Arthurian epic occurs in the proem to book 9 of Paradise Lost, in which he seemingly refuses to debase his current project with the trivialities of chivalric romance. His loftier subject will instead be the tragedy of Adam and Eve. Milton's account of the Fall is obviously a Christian tragedy with classical precedents. However, judging by the frequency with which it follows romance conventions, book 9 of Paradise Lost can also be read as a chivalric tragedy, a mode not only familiar to Milton's contemporaries but also well suited to his political agenda and lifelong fondness for Arthurian literature. In fact, the proem does not reject romance outright, only a particular model associated with royalist propaganda. Its purpose is instead to prepare the reader, in true romance fashion, for the hero's choice between the genre's more superficial trappings and the righteous quests of the truly chivalrous.
Similarity, Attraction, and Compromise Effects: Original Findings, Recent Empirical Observations, and Computational Cognitive Process Models
Authors: Wollschlaeger Lena M. , Diederich Adele
Published: February 2020

Preference reversals—a decision maker prefers A over B in one situation but B over A in another—demonstrate that human behavior violates invariance assumptions of (utility-based) rational choice theories. In the field of multi-alternative multi-attribute decision-making research, 3 preference reversals received special attention: similarity, attraction, and compromise effects. The 3 so-called context effects are changes in (relative) choice probabilities for 2 choice alternatives after a third “decoy” option is added to the set. Despite their simplicity, the effects demonstrate that choice probabilities in multi-alternative decision making are contingent on the local context, that is, on the choice set under consideration. Because of their simplicity, on the other hand, similarity, attraction, and compromise effects have been successfully examined in numerous studies to date, and they have become of increasing interest for differentiating between computational cognitive process models of multi-alternative multi-attribute decision making. However, the stimulus arrangement for producing the effects seems to vary between studies, which becomes challenging when model accounts are compared. The purpose of this review is to present various paradigms in a coherent way and describe various model accounts based on a common structure.
The Impact of Stock Characteristics on Its Market Price in Jordanian Commercial Banks
Authors: Taher Shammout Belal Rabah
Published: February 2020

The study aims at identifying the impact of stock characteristics represented by (Earnings Per Share (EPS), Book Value Ratio (BVR), Dividends Per Share (DPS), Dividends Payout Ratio (DPR), Market to Book Ratio (MBR), Price Earnings Ratio (PER), and Yield Per Share (YPE)) on the market stock price in the 13 commercial banks in Jordan during the period from 2005 to 2018. Multiple Linear Regression has been used to illustrate the impact of the independent variables and the controlling variables on the dependent variable.

The study has found that there is a significant impact of stock characteristics on its market price at the Jordanian commercial banks. The study also found a statistically significant impact for each book value ratio, dividends per share, market to book ratio, price-earnings ratio, and yield per share on the market price at the Jordanian commercial banks. However, there was no statistically significant effect for each of the earnings per share and dividend’s payout ratio on the market price at the Jordanian commercial banks. The study recommends that investors, analysts, and decision-makers use the characteristics of stocks when carrying out analyses before making important investment decisions that can affect their wealth in the future through forecasting stock prices.
“Carrying the organ” – the thing on the portative, Part 1
Authors: Dziewiecki Piotr
Published: February 2020

The present article is aimed at outlining the history and form of instruments known as portatives. Its continuation will be a paper devoted to discussing technical issues connected with designing and constructing Opus 1 Portative built by the author.
The portative is an instrument belonging to the family of keyboard aerophones. It is the smallest representative of the pipe organ family – both in terms of its sound range and size.
As there are not many historical instruments preserved to this day, we draw information on their form and use from how they are depicted in art. It is a testament of the evolution of portatives and their popularity – from the first mentions about them from the beginning of the 12th century to the16th century when their significance lessened. This drop in popularity of these instruments was probably connected with their technical limitations noticed at that time, the fact that they were unable to meet the requirements of the evolving music and they became ousted by other portable instruments.
The construction of the portative is similar to the construction of the full-size pipe organ. We can notice the occurrence of similar components, only in a simplified and smaller form. An important discrepancy is a different treatment of air system – the portative usually has only one wedge bellow operated by the player, which allows to very precisely control the air pressure, and that is connected with the dynamics and tone colour of sound produced by the pipes. This results in playing music characteristic of portatives, i.e., similar to vocal music having greater phrasing capacities as compared to playing the full-size pipe organ.
Despite the decline of interest in portatives, which could be noticed in the 16th century, nowadays portatives have been regaining popularity with musicians and organ builders. They all want to build instruments with a high level of historical accuracy as well as create portatives with modern features. Examples of the first trend can be found in Marcus Stahl’s workshop, whereas the instrument built by me follows the second trend. A great model of a portative combining both ideas is one constructed by Bartosz Żłóbiński.
Recepcja niemieckiej pedagogiki kultury w polskiej humanistyce
Authors: Szymański Mirosław S.
Published: February 2020

The starting point for the discussion is the obvious statement that cultural pedagogy is one of the three main currents in German education sciences; the other two are empirical and critical pedagogy. As the title suggests, the author focuses on cultural pedagogy only, and in particular on the reception of German cultural pedagogy by Polish cultural pedagogy during the interwar period. One can definitely say that German Geisteswissenschaften, or “the sciences of spirit” (including pedagogy) influenced Polish humanities. The main thesis of the article is that although the geisteswissenschaftliche Pädagogik had an overwhelming influence on pedagogical thinking and actions in Poland before World War II, it became considerably marginalised or almost totally forgotten after the war, as it was proclaimed a “bourgeois relic” and an “old fashioned trinket”. Theodor Litt (1880–1962) and Eduard Spranger (1882–1963) are commonly considered the leading representatives of German cultural pedagogy, and their Polish counterparts are Bogdan Nawroczyński (1882–1974) and Bogdan Suchodolski (1902–1993). The article refers to original source literature – although in brief – to discuss the influence of the educational concepts of the former group on the latter one. By proposing such analysis, the author hopes for fair and critical restructuring of cultural pedagogy in Poland, if not for its revitalisation. The first signs are already there.
Wsparcie społeczne dziecka w sytuacji ubóstwa – przykład rwandyjski
Authors: Babicki Zbigniew
Published: February 2020

The phenomenon of poverty occupies an important place in the discourse on the problem of exclusion and social marginalisation. The problem of children in a poverty situation is most often analysed through the prism of family poverty. Meanwhile, it is worth noting that poverty in childhood has a different dimension than in adulthood, because it disturbs the proper development of the child. Children’s experience of poverty affects their further life, often with irreversible consequences. Numerous institutions and individuals offer their help and support to improve the lives of children in Africa. This activity takes the form of either immediate or long-term help. One of those institutions that actively participate in solving the problem of poverty in Africa is the Catholic Church. Its involvement in helping children in a poverty situation is an important dimension of social support.
Workflows Científicos com Apoio de Bases de Conhecimento em Tempo Real
Authors: Bursztyn Victor S. , Dias Jonas , Mattoso Marta
Published: February 2020

One major challenge in large-scale experiments is the analytical capacity to contrast ongoing results with domain knowledge. We approach this challenge by constructing a domain-specific knowledge base, which is queried during workflow execution. We introduce K-Chiron, an integrated solution that combines a state-of-the-art automatic knowledge base construction (KBC) system to Chiron, a well-established workflow engine. In this work we experiment in the context of Political Sciences to show how KBC may be used to improve human-in-the-loop (HIL) support in scientific experiments. While HIL in traditional domain expert supervision is done offline, in K-Chiron it is done online, i.e. at runtime. We achieve results in less laborious ways, to the point of enabling a breed of experiments that could be unfeasible with traditional HIL. Finally, we show how provenance data could be leveraged with KBC to enable further experimentation in more dynamic settings.

On the basis of Section 11 (5) of the AÜG – a provision fundamentally modified in 2017 – the study provides comprehensive answers to questions arising from the prohibition of deploying temporary agency workers as strike breakers, in particular with regard to labour law, civil law and constitutional law. Apart from that, the provision is integrated into the overall structure of industrial action law and remaining options for employers to defend against strikes in the future are pointed out. In addition, any effects under industrial constitution law are discussed for all measures of deploying external personnel in industrial actions.
Das Unternehmensinteresse - Maßstab für die Organwalter der Aktiengesellschaft
Authors: Schubert Claudia
Published: February 2020

The so-called company interests determine the directors’ duties within a corporation. There has been an ongoing discussion of this term in German company law for the last 100 years. Recently, it has been receiving new impetus through the ongoing development of corporate social responsibility and the debate about sustainability and the commitment of companies to the pursuit of public interests. To date, German legislation remains unchanged, but the key provision of the French Civil Code (Art. 1832) has been altered in 2019. Against this backdrop, this book analyses company interests as a crucial standard for directors’ duties, their derivation and repercussions. The directors have to ensure the long-term viability of the company, taking into account the benefit of its shareholders as a whole, as well as the interests of the company’s employees. Additionally, the company’s interest, in protecting its reputation, serves as a gateway for the director’s regard to the company's business relationships, business conduct and the public interest, but at the same time, it sets limits for this regard. Further limitations to protect public interests need prohibition statutes.
The Rise and Decline of Car Use in Beijing and Shanghai
Authors: Gao Yuan , Newman Peter , Kenworthy Jeffrey
Published: February 2020

Chinese cities have primarily evolved around walking, bicycling and public transport with their dense, linear form and mixed land use. The recent urban growth spurt has involved private motorisation, but because of land constraints and not fearing urban density, as in Anglo-Saxon cities, the same dense urbanism has been maintained. This means that automobiles do not easily fit into this traditional fabric and especially the historic walking fabric. Issues like congestion and air quality have become major constraints to further growth. Using Beijing and Shanghai as case studies, the next phase of urban and transport development now appears to be to reduce car use with the dramatic growth in urban rail as in most developed cities in the twenty-first century. This decoupling of car use from economic growth is consistent with other developed cities but is a first for emerging cities, hence the paper aims to explain this pattern from the cultural, political and especially urban fabric perspectives. The application to other Chinese cities and emerging cities is now possible following Beijing and Shanghai’s lead.

El objetivo del presente estudio fue conocer la tipología de los goles marcados en el fútbol profesional español mediante un análisis observacional. Los 1137 goles (508 en Primera división y 629 Segunda división) marcados en los 421 partidos de fútbol correspondientes a la temporada 2017-2018 en Primera y Segunda división fueron analizados. Todos los goles se clasificaron en función de su tipología. De manera general, la mayoría de los goles se anotaron con las extremidades inferiores, al primer toque y desde dentro del área. No se obtuvieron diferencias significativas (p > 0,05) al comparar la tipología de los goles en función de la categoría de la competición. Sin embargo, se observaron diferencias significativas (p < 0,05) al comparar los diferentes puestos específicos. Los resultados obtenidos sugieren que se deben plantear tareas de entrenamiento específicas, en función del puesto específico, con el fin de optimizar el rendimiento de cara a gol de los futbolistas.

The aim of the present investigation was to know the typology of the goals scored in Spanish professional soccer through an observational analysis. 1137 goals (508 First division and 629 Second division) scored in 421 soccer matches corresponding to the 2017-2018 season in First and Second division were analyzed. All the goals were classified according to their typology. In general, most of the goals were scored with the legs, at the first touch and from within the area. No significant differences were obtained (p> 0.05) when comparing the typology of goals according to the category of the competition. However, significant differences were observed (p <0.05) when comparing the different playing positions. The results obtained suggest that specific training tasks should be proposed, depending on the playing position, in order to optimize the performance of the players' goal.

Insurance Sector Development and Foreign Direct Investment in Nigeria
Authors: Eze Gbalam Peter , Timipere Ekokeme, Tamaroukro
Published: February 2020

Aims: The study examined the impact of insurance sector development on foreign direct investment in Nigeria.

Study Design: The ex-post facto research design was employed to observe the study components in retrospect. Secondary data spanning 1996 to 2017 was sourced and collated from the World Development Indicators, Central Bank of Nigeria statistical bulletin and National Insurance Commission annual balance sheets.

Place and Duration of Study: Department of Banking and Finance, Niger Delta University, Wilberforce Island, Bayelsa State, Nigeria. The study was carried out between November 2019 to January 2020.

Methodology: The ex-post facto research design was employed to observe the study components in retrospect. Secondary data spanning 1996 to 2017 was sourced and collated from the World Development Indicators, Central Bank of Nigeria statistical bulletin and National Insurance Commission annual balance sheets. The time series data was estimated using the least square technique.

Results: The results indicates that; the total asset size of the insurance sector exerts a negative and statistically insignificant impact on foreign direct investment inflow to Nigeria, total insurance business investment exerts a positive and statistically insignificant impact on foreign direct investment inflow to Nigeria and finally, total insurance premium exerts a negative and statistically significant impact on foreign direct investment inflow to Nigeria.

Conclusion: The study concludes that insurance sector development does not attract foreign investment inflow to Nigeria. The study recommends that the insurance sector should be revamped in order to absorb risk and uncertainty and be a vehicle for risk transfer and minimization. A policy of restructuring would help instil public confidence, boost insurance policy sales, increase insurance premium and invariably increase the availability of investible funds to boost economic activity. The study suggests that these would help attract foreign direct investment to meet domestic funding needs of Nigeria.
Genetic Divergence Studies for Anaerobic Germination Traits in Rice (Oryza sativa L.)
Authors: Sudeepthi K. , Srinivas T. , Kumar B. N. V. S. R. Ravi , Jyothula D. P. B. , Umar Sk. Nafeez
Published: February 2020

The present investigation was carried out to study the inherent genetic diversity of 107 rice genotypes towards development of rice varieties with tolerance for germination under anaerobic conditions for use in wet direct seeded rice cultivation system. The diversity was evaluated using multivariate analysis technique of Mahalanobis D2. The 107 rice genotypes studied were grouped into nine clusters. Twenty nine genotypes were grouped in cluster II followed by 27, 22, 10, 11 and 5 genotypes each in clusters I, III, IV, VI and cluster VII, respectively. The pattern of distribution of genotypes into various clusters was observed to be at random with no relation to geographical diversity. Results on inter-cluster distances revealed maximum diversity between genotypes of cluster VII and cluster IX, while intra-cluster distance was noticed to be maximum for cluster VI. Cluster IX had recorded higher cluster mean values for all the traits studied. Further, the traits, namely, shoot length, seedling dry weight and anaerobic response index together accounted for 62.45 per cent of the total genetic divergence in this study.

Common bile duct metastasis from recurrent adenocarcinoma of lung: A case report
Authors: Yeo Kai‐Fuan , Chien Belle Pei‐Erh , Tsai Ming‐Chang , Wang Chi‐Chih , Yang Tzu‐Wei
Published: February 2020

Obstructive jaundice caused by metastasis of lung cancer to distal common bile duct (CBD) is extremely rare. Here, we report a 70‐year‐old man presented with progressive jaundice and generalized weakness for 1 month. He had a medical history of stage IIB (pT2N1M0) lung adenocarcinoma, for which he had undergone surgical treatment and subsequent adjuvant chemotherapy 3 years ago. Endoscopic retrograde cholangiopancreatography (ERCP) revealed a distal CBD stricture. Histopathological examination of the biopsy specimen taken from the stricture site demonstrated adenocarcinoma with positive for cytokeratin‐7 and thyroid transcription factor‐1 on immunohistochemistry. The findings confirmed the diagnosis of metastasis of recurrent lung adenocarcinoma to the CBD. The patient's jaundice improved after insertion of an endoscopic retrograde bile duct (ERBD) drainage plastic stent at the time of ERCP. He was then started on target therapy with afatinib after discharge. The ERBD stent was removed 3 months later. He had remained in stable condition without jaundice during the 1‐year follow‐up period. In conclusion, obstructive jaundice caused by metastatic adenocarcinoma to the CBD is a rare manifestation of lung cancer. An accurate diagnosis is crucial in further treatment for such a patient.
Designing real time model mobile monitoring system for model predictive control in a nonlinear continuous stirred tank reactor
Authors: Djarum Danny Hartanto , Ahmad Zainal
Published: February 2020

A continuous stirred tank reactor (CSTR) plays a major role in many process industries, and its control strategy could be very critical in achieving desirable yields, conversion, rates, and minimizing the formation of side products. CSTR control over a wide operating range has been a major issue to control engineers as it exhibits a highly nonlinear behaviour and time varying behaviour. A traditional control mechanism like a proportional–integral–derivative (PID) controller although still widely used, may not be sufficient in achieving optimum performance and robustness. In this study, model predictive control (MPC) strategy is developed for a nonlinear dynamic CSTR process, and the performance was compared with the traditional PID controller. The result shows that for a small set point change, MPC has similar performance to the PID controller. MPC performed much better when subjected to a much larger set point change in which the response time is 12 times faster and is able to reduce up to 60% of the loop interaction. The second part of this study is to design a real‐time mobile monitoring system (proof of concept). The overall design allows for real‐time updates on the performance of CSTR remotely. Engineers will be notified when the equipment fails to run at its full performance and generate critical analysis based on the historical data of the equipment. Lastly, a real‐time safety alert allows accidents to be predicted ahead before it happens and allows workers to be notified in real time.
“Easterlies”‐induced precipitation in eastern Patagonia: Seasonal influences of ENSO'S FLAVOURS and SAM
Authors: Agosta Eduardo A. , Hurtado Santiago I. , Martin Paula B.
Published: February 2020

The seasonal influence of the phases of El Niño‐Southern Oscillation (ENSO) and of Southern Annular Mode (SAM) on precipitation over eastern Patagonia is examined. Also, their impact in generating persistent daily easterly moisture flux leading to daily precipitation events. The significant signatures of the drivers on precipitation are found in March–April–May (MAM), June–July–August (JJA) for ENSO and November–December–January (NDJ) for SAM. Over the east coast, precipitation is mainly favoured owing to an overall growth of the seasonal mean number of precipitation days (~30%) by central Niño in JJA and by negative SAM phase in NDJ, and growth of the frequency of persistent events of daily westward moisture flux (~90%) by eastern Niña in MAM. A great spatial variability shapes the anomalies. Evidence is shown for weakened seasonal westerlies linked to Eastern Pacific Niño in MAM. Enhanced daily easterlies with net daily westward moisture flux in the region lead to strong daily precipitation. Growth in precipitation intensity in the northeast coast is also associated with Eastern Pacific Niño in MAM. In the interior lands, south of 45°S, westward moisture flux is increased up to ~200% by negative SAM phase in NDJ. The nature of extratropical low‐frequency transient eddies travelling over the South Pacific will influence the frequency and intensity of daily local precipitation as well as the persistent westward flux during ENSO events.
Fuzzy neural network analysis on the compacted graphite iron with improved tensile and heat transport properties

Published: February 2020

In order to find out the most effective method for developing compacted graphite iron with a combination of high tensile strength, ductility and thermal conductivity, the superposed structural effects were investigated by experimental results and the relative significances were ranked on the basis of fuzzy neural network model. The concerned structural parameters consisted of graphite content, vermicularity and microhardness of the matrix. It was found that the relationships between properties and structural parameters become complex due to the mutual disturbances of various characteristics. Irregular and compossible corrections were both observed. The sensitivity level suggested that low microhardness of the matrix and low vermicularity are the optimal directions for improving simultaneously the tensile strength, thermal conductivity and elongation of compacted graphite iron.

Effects of shooting distance and projectile on modal and sound characteristics are examined. Results are given in tabular and graphical forms.
Photodynamic inactivation of antibiotic‐resistant Gram‐positive bacteria: Challenges and opportunities
Authors: Malik Zvi
Published: February 2020

The growing numbers of pathogenic bacteria acquiring multidrug resistance are posing the challenges to develop novel therapeutic approaches. Photodynamic bacterial inactivation assaults multiple subcellular targets of pathogenic bacteria, including Staphylococcus aureus, with low tendency to induce further resistance. A wide range of aPDI photosensitizers were investigated for localized infections, including endogenous porphyrins and encapsulated sensitizers in nanoparticles. This mini review presents the concepts of aPDI, a field consisting of more than 3000 research articles published over 30 years. Mutated PBP membrane enzymes of multiantibiotic resistant S. aureus are plausible targets of aPDI. Synergistic aPDI using simultaneously DP, light irradiation and the antibiotic oxacillin, was recently described, eliminating temporarily oxacillin resistance. Additive antimicrobial effects were achieved with DP‐aPDI combined with additional classes of antibiotics. We propose that mutual aPDI adjuvant with antibiotics or other toxic molecules is opening a new therapeutic window for topical life‐threatening infections, without induction of further resistance.

Wohn- und Hausgemeinschaften in stationären und ambulanten Settings
Authors: Steiner Barbara
Published: February 2020

Hintergrund und Fragestellung

Ambulante und stationäre Wohn- und Hausgemeinschaften unterscheiden sich von klassisch stationären Angeboten durch eine Orientierung an der Autonomie der Bewohner*innen und die Normalität von Wohnen und Alltag in der Häuslichkeit. Der konzeptionelle Rahmen, hier als unterstütztes Wohnen (UW) gefasst, zeichnet sich durch eine Wohnumwelt, das Führen eines eigenen Haushalts, Kleinräumigkeit und Überschaubarkeit aus. Personelle Präsenz in neuem Personalmix stützt Qualitäten wie soziale Teilhabe, sinnvolle Tätigkeit und funktionale Unterstützung. Die Studie untersucht, wie sich dieser Bezugsrahmen auf die Lebensqualität der Bewohnerschaft auswirkt, und reflektiert die Perspektiven für die weitere Entwicklung von Wohnoptionen.

Material und Methode

Im Zeitraum von 9 Monaten (2006–2007) wurden 8 Wohn- bzw. Hausgemeinschaften mit 73 Bewohner*innen und ein klassischer Pflegeheimbereich mit 18 Bewohner*innen in den Dimensionen Verhaltenskompetenz, subjektives Wohlbefinden, wahrgenommene Lebensqualität und objektive Umwelt untersucht. Es kamen multidimensionale personen- und umweltbezogene Instrumente zur Anwendung; zu organisationsspezifischen Fragen wurden qualitative Interviews durchgeführt.

Ergebnisse

In den Haus- und Wohngemeinschaften des UW sind ungeachtet einer formal stationären oder ambulanten Einordnung bei den Bewohner*innen signifikant höhere Wohlbefindenswerte und signifikant weniger agitierte, herausfordernde Verhaltensweisen als im Pflegeheim zu beobachten. Insbesondere Menschen mit Demenz profitieren von der spezifischen Qualität des UW, das sich in wesentlichen Dimensionen abbildet.

Schlussfolgerung

Die Befunde geben Hinweise dafür, dass das UW ein Konzept darstellt, das Basis für neue Wohnangebote und eine neue Versorgungsinfrastruktur sein kann. Es bietet gute Anknüpfungspunkte an das Leitprinzip der geteilten Verantwortung.
Influence of a Planning Intervention on Physical Activity Behavior: the Moderating Role of Intentions and Executive Functions in a Randomized Controlled Trial
Authors: Pfeffer Ines , Strobach Tilo
Published: February 2020

Background

Planning and executive functions (EFs; inhibition, updating, shifting) are self-regulatory variables that help people to become and stay physically active. The aim of this study was to examine how and for whom a planning intervention affects physical activity (PA) behavior in the short term. Therefore, the mediating role of planning and the moderating role of intentions and EFs for the planning–behavior link were examined.

Method

In a randomized control trial with two treatment groups (planning group vs. control group) and two points of measurement (t1 and t2, 1 week apart), n = 200 students participated in both measurements. At t1, participants filled in standardized questionnaires assessing PA behavior, intention, and planning. Computer-based tests assessed the following EFs: inhibition, updating, and shifting. At t2, planning and PA behavior were measured again. Moderated mediation analyses were conducted.

Results

A significant increase in PA between t1 and t2 was found for the planning group compared with the control group. Furthermore, planning cognitions significantly mediated the effect of the planning group on behavior and intention, as well as the EF updating moderated the association between planning and behavior. Forming plans was particularly beneficial for participants with high intentions and lower updating performance.

Conclusion

Planning enhances PA behavior, particularly when PA intention is high. Poor performance in updating can be compensated by planning since encouraging people to generate plans might facilitate automatic enactment of the behavior.
Gesprächszeit für belastete Angehörige
Authors: Kunz Renate
Published: February 2020

Zusammenfassung. Krankenhäuser sind für viele Menschen Orte, die nicht nur mit der Hoffnung auf Heilung, gute Pflege und Fürsorge verbunden sind, sondern auch mit starken Gefühlen der Angst und Ohnmacht. Nirgendwo sonst erleben Menschen sich so unmittelbar und unvermeidbar konfrontiert mit existentiellen Lebensthemen wie Krankheit und Leid, Sterben und Tod. Insbesondere die Angehörigen schwerstkranker Patienten fühlen sich oft überfordert und allein gelassen. „Ich stand auf dem leeren Flur vor dem Zimmer meiner Frau und die Welt ging unter. Wie und warum sollte ich weiterleben?“ (Zitat Angehörigengespräch)
