Podłużne badanie jakościowe doświadczenia wolontariuszy sprawujących opiekę nad pacjentami w ramach programu profilaktyki powikłań hospitalizacji osób starszych na oddziale chorób wewnętrznych – Projekt Zdrowy Kontakt

Podłużne badanie jakościowe doświadczenia wolontariuszy opiekujących się pacjentami oddziału geriatrycznego szpitala chorób wewnętrznych zostało przeprowadzone w ramach Projektu Zdrowy Kontakt. Jest to pierwszy w Polsce i Europie Środkowo-Wschodniej program niefarmakologicznego zapobiegania majaczeniu szpitalnemu, które jest częstym powikłaniem hospitalizacji osób starszych. Wolontariuszami programu są studenci psychologii, pielęgniarstwa i medycyny, którzy odwiedzają chorych w szpitalu i realizują złożoną interwencję profilaktyczną. Badanie przeprowadzono, korzystając z podejścia idiograficznego, w formie cyklu interpretatywnych studiów przypadku. Z ośmiorgiem uczestników badania przeprowadzono po dwa częściowo ustrukturyzowane wywiady – przed rozpoczęciem wolontariatu i po jego zakończeniu. Celem powtórzonych rozmów było opisanie zmian, jakie mogły zajść w doświadczeniu, motywacji, przekonaniach i rozumieniu siebie przez studentów pod wpływem udziału w wolontariacie na oddziale geriatrycznym. W badaniu skorzystano z metody interpretatywnej analizy fenomenologicznej, analizę danych jakościowych przeprowadzono z pomocą oprogramowania Atlas.ti. W wyniku badania uzyskano złożone opisy indywidualnego doświadczenia badanych związanego z ich pracą na oddziale. Ujawniły się również motywy wspólne dla większości z nich. Do najpoważniejszych należy zetknięcie się z myślą o śmierci i próby nawiązania relacji z pacjentami, z którymi kontakt jest utrudniony z powodu zmian otępiennych, skutków udaru lub zaburzeń poznawczych i percepcyjnych występujących w majaczeniu szpitalnym. Związana z kontekstem geriatrycznym i wynikająca z profilaktycznego oraz behawioralnego charakteru interwencji trudność w dostrzeżeniu przez wolontariuszy efektów swojej pracy okazała się w największym stopniu zniechęcać ich do odwiedzin na oddziale. Najważniejszym wyodrębnionym w badaniu tematem jest relacja sfery osobistej i profesjonalnej w opiece nad pacjentami. Uzyskany opis i próba zrozumienia doświadczenia studentów kierunków medycznych działających jako wolontariusze na oddziale geriatrycznym może posłużyć jako punkt wyjścia do refleksji nad perspektywą personelu medycznego i możliwymi formami wsparcia chroniącymi go przed nadmiernym obciążeniem, stresem i wypaleniem zawodowym. Może być także źródłem inspiracji dla kształcenia przyszłych kadr medycznych.
Involvement of Probiotics and Postbiotics in the Immune System Modulation

Intestinal microbiota interacts with other systems, especially the immune system, which is responsible for protecting the body by recognizing “stranger” (pathogen associated molecular patterns-PAMPs) and “danger” (damage-associated molecular patterns-DAMPs) molecular motifs. In this manner, it plays an important role in the pathogenesis of various diseases and health. Despite the use of probiotics that modulate the intestinal microbiota in providing health benefits and in the treatment of diseases, there are some possible concerns about the possibility of developing adverse effects, especially in people with suppressed immune systems. Since probiotics provide health benefits with bioactive compounds, studies are carried out on the use of products containing non-living probiotic microorganisms (paraprobiotics) and/or their metabolites (postbiotics) instead of probiotic products. It is even reported that these microbial compounds have more immunomodulatory activities than living microorganisms via some possible mechanism and eliminates some disadvantages of probiotics. Considering the increasing use of functional foods in health and disease, further studies are needed with respect to the benefits and advantages of parabiotic and/or postbiotic use in the food and pharmaceutical industry as well as immune system modulation. Although probiotics have been extensive studied for a long time, it seems that postbiotics are promising tools for future research and applications according to the recent literature. This review aimed to evaluate the interaction of probiotics and postbiotics with the immune systems and also their advantages and disadvantages in the area of food-pharmaceutical industry and immune system modulation.
Nigeria’s Domestic Public Debts and Economic Development

This study investigates the effect of Nigeria’s domestic public debt on economic development of Nigeria spanning from 1981-2018. This is in response to the doubts being raised in some quarters as to whether the continuous increase in domestic debt over the years has led to the economic development of Nigeria as the former has been known to influence the later if well harnessed and executed. The secondary data used in the study were sourced from Central Bank of Nigeria Statistical Bulletin, Debt Management Office of Nigeria, World Bank Development Indicators and United Nations Development Program. The study made use of Ordinary Least Square Regression tools to determine the statistical relationship between Nigeria’s domestic public debt profile and Human Development Index as well as private sector investment. The outcome of study in the first model showed that domestic debt servicing and state governments’ domestic debts are significantly related to economic development. On the other hand, Federal domestic debt and State domestic debt are significantly related to private sector investment. The study therefore recommends that government should be cautious in her domestic borrowing policy given that servicing debt always becomes a burden to the sustainability of economic gains, in addition to its tendency of crowding-out private sector investment in Nigeria.
The relationships among mobile travel application attributes, customer engagement, and brand equity

In this study we investigated the relationships among mobile travel application (app) attributes, customer engagement, and brand equity with 518 participants who were current users of these apps. Results show that perceived usefulness, perceived price advantage, and user interface attractiveness positively influenced customer engagement with mobile travel apps, whereas perceived ease of use had no significant effect. Additionally, mobile travel app engagement was found to be significantly and positively related to brand awareness and brand loyalty. Finally, mobile travel app engagement mediated the effects of perceived usefulness, perceived price advantage, and user interface on both brand awareness and brand loyalty. Our findings indicate that improving travel app attributes enhanced customer engagement with these apps, and this, in turn, increased brand equity.
Linear and Quadratic Leap-and-Land Trajectory Tracking Algorithms

Considered in this note are numerical tracking algorithms for the accurate following of implicit curves. We start with a fixed point on the curve, and then systematically place on it additional points, one after the other. In this note we first go over the basic procedure of moving forward tangentially from an already placed point then orthogonally returning to the curve. Next, we further consider higher order forward stepping procedures for greater accuracy. We note, however, that higher order methods, desirable for greater accuracy, may harbor latent instabilities. This note suggests ways of holding such instabilities in check, to have stable and highly accurate tracing methods. The note has several supporting numerical examples, including the rounding of a dynamical “snap-through” point.
Unbundling the Effects of Internationalization on Firm Performance in Emerging Economies: The Moderating Effects of Strategic Resource Decisions

The authors investigate how strategic resource decisions—regarding slack resources and strategic marketing ambidexterity—influence the relationship between internationalization and firm performance of emerging-market firms. Drawing on the resource-based view, the authors synthesize two dominant, yet divergent, perspectives that explain the respective resource slack advantages and liabilities in the internationalization literature: the flexible capacity and the efficient capacity perspectives. They also explore the moderating role of strategic marketing ambidexterity, which comprises a bundle of marketing activities covering both exploitation-dominant actions and exploration-dominant actions. The authors empirically examine the hypothesized relationships with data from a sample of 1,683 firm-year observations for the period between 2005 and 2018 and find that distinct forms of resource slack have contrasting effects on the relationship between internationalization and performance. The results provide strong evidence for a positive moderation effect of unabsorbed slack resources and a negative moderation effect of absorbed slack resources on the internationalization–performance relationship. The authors also find a nonsignificant moderating effect of strategic marketing ambidexterity, demonstrating that internationalization results in higher firm performance regardless of the firm’s exploration-dominant or exploitation-dominant strategic emphasis in emerging economies.
A review of wind turbine drivetrain loads and load effects for fixed and floating wind turbines

Drivetrain is one of the important subsystems in the wind turbine and faults and damages in the drivetrain significantly affect the wind turbine's downtime and nonavailability. Understanding the drivetrain dynamics and load effects that results in failures has been a major research area due to challenges in the drivetrain operations and maintenance. A systematic literature review of wind turbine drivetrains is presented according to key research areas of drivetrains, such as modeling and load effects on the drivetrain. Special emphasis is given for the floating wind turbine drivetrains. A review on the state‐of‐art modeling techniques of the drivetrain is presented. Studies concerning the aeroelastic load effects on the drivetrain components especially the gearbox and the bearings are discussed. Several key aspects such as aero‐hydro‐elastic interaction load effect and platform motion excitations on the floating wind turbine drivetrain dynamics are reviewed in detail. Finally, challenges related to floating wind turbine drivetrain are also discussed.
Efficiency Comparison of Public Bike-Sharing Repositioning Strategies Based on Predicted Demand Patterns

Public bike-sharing systems are used worldwide, and the imbalance between supply and demand for bicycles and operational inefficiency is becoming increasingly severe. For a system to operate efficiently, it is necessary to relocate bicycles among rental stations to minimize a lack of bikes at the station causing unmet demand. Recent studies have presented various repositioning strategies for bike-sharing systems and compared their efficiency. However, little consideration has been paid to the strategy of the spatial and temporal patterns of bike-sharing demand and the inventory level. This study aims to analyze the spatiotemporal patterns of the forecasted demand for the bike-sharing system and to compare the efficiency of different repositioning strategies to choose the most efficient one. We use three repositioning strategies with different additional constraints related to unbalanced stations and present computational results with real data in Seoul. Two indices represent the temporal variation of predicted inventory at each station and the coefficients of the spatial variation for hourly unmet demand. Linear classifiers are derived by linear discriminant analysis to classify the efficiency of each strategy according to developed indices. The study reveals that adding constraints of imbalanced stations to the strategy according to the spatiotemporal characteristics of forecasted inventory can help to reduce unmet demand. The result of this study enables proactive decision-making using proposed indices in operating bike-sharing systems and contributes to improving the efficiency and reliability of systems.
Phylogeny, classification, and biogeography of Afrotrichloris, Apochiton, Coelachyrum, Dinebra, Eleusine, Leptochloa, Schoenefeldia, and a new genus, Schoenefeldiella (Poaceae: Chloridoideae: Cynodonteae: Eleusininae)

To investigate the evolutionary relationships among species of Afrotrichloris, Apochiton, Coelachyrum, Dinebra, Eleusine, Leptochloa, and Schoenefeldia of subtribe Eleusininae, a phylogeny based on DNA sequences from nine gene regions (ITS, rps16‐trnK, rps3, rps16, rpoC2, rpl32‐trnL, ndhF, ndhA, ccsA) is presented. Previous molecular phylogenies indicated that Coelachyrum was polyphyletic and Schoenefeldia was paraphyletic, with Afrotrichloris embedded within it. Apochiton burttii was embedded in the Coelachyrum clade paired with C. longiglume, Coelachyrum poiflorum was placed outside of Coelachyrum and sister to Eleusine, and Schoenefeldia is paraphyletic, with its two species forming a grade sister to Afrotrichoris. Our molecular phylogeny supports recognition of a new genus, Schoenefeldiella, and a new combination, Schoenfeldiella transiens. In addition, we provide generic emendations for Coelachyrum, which now includes five species including a new combination proposed here, Coelachyrum burttii, and Eleusine, which now includes 11 species.
Religiosity As a Mediator Variable Influence Between Character Strength and Parent Attachment On The Resilience Of Adolescent Victims Of Earthquake and Tsunami Living On The Coastal, Banten

This study aims to test the fit model of the influence of character strength and parent attachment on resilience mediated by the religiosity of adolescent victims of the earthquake and tsunami who live on the coast. The conceptual used to explain resilience is based on the socio-ecological perspective of Ungar & Liebenberg (2013). Character strength uses the theory of Seligman (2006). The concept of parent attachment is explained based on Armsden and Greenberg's (1987) theory. And the concept of religiosity is based on Fetzer's theory (1999). The measuring instrument used to measure resilience is YCRM, character strength using VIA-IS for youth, parent attachment using IPPA, and religiosity using the religiosity scale. The data analysis technique used in this study was the Structural Equation Model (SEM) with the help of Amos software. The results showed that the model of the influence of character strength and parent attachment on resilience mediated by the religiosity of youth victims of the earthquake and tsunami living on the coast is fit with the data. Religiosity acts as a mediator of the influence variable between character strength and parent attachment on the resilience of adolescent victims of the earthquake and tsunami living on the coast.
Gender and Digital Public Relations: Who Gets Benefits?

Public relations professionals have been dominated by females since they have good communication skills and abilities in persuading and engaging in the conversation and listening the stakeholders to build and harmonize relationships them. However, male public relations practitioners dominate in the top positions since they have been participated in the managerial roles while female are in the technical roles. In the organization, female public relations practitioners face inequalities in social, professional, and economic areas and they also find it difficult to achieve higher position because the traditional patriarchy is still strongly practiced. It harder for them to break this barrier. Family and children, on the other hand, become big considerations for females to climb the higher position since it will give bigger responsibilities. Moreover, the massive development of digital technologies provides more opportunities for female public relations professionals to intensively engage with the stakeholders. On the other hand, these technologies bring privilege for males since they are more digital technical skills. To compete with males in digital public relations, females should enhance their digital skills, wisely manage their time, learn to take new challenges making them one step ahead, and actively participate in every organizational activity to voice their ideas and straighten up false assumptions and misconceptions about females. Meanwhile, males should be versatile public relations professionals in the digital era by combining masculine and feminine values to find the best public relations practices.
Serum anti-CRP antibodies differentiate etiology and predict relapse in acute tubulointerstitial nephritis

ABSTRACT Introduction Acute tubulointerstitial nephritis (ATIN) is a common cause of acute kidney injury with various etiologies. It has been shown that autoimmune-related ATIN (AI-ATIN) has a higher recurrence rate and a greater likelihood of developing into chronic kidney disease compared with drug-induced ATIN, yet misdiagnosis at renal biopsy is not uncommon. Methods Patients who were clinicopathologically diagnosed as ATIN from January 2006 to December 2015 in Peking University First Hospital were enrolled. Clinical, pathological and follow-up data were collected. Serum samples on the day of renal biopsy were collected and tested for anti-C-reactive protein (CRP) antibodies. CRP and its linear peptides were used as coating antigens to detect antibodies. Statistical analysis was used to assess the diagnostic value of the antibodies. Results Altogether 146 patients were enrolled. The receiver operating characteristic–area under the curve of the anti-CRP antibody for the identification of late-onset AI-ATIN was 0.750 (95% confidence interval 0.641–0.860, P < 0.001) and the positivity was associated with ATIN relapse (adjusted hazard ratio = 4.321, 95% confidence interval 2.402–7.775, P < 0.001). Antibodies detected by CRP linear peptide 6 (PT6) were superior with regard to differentiating patients with AI-ATIN, while antibodies detected by peptide 17 (PT17) could predict ATIN relapse. Antibodies detected by these two peptides were positively correlated with the severity of tubular dysfunction and pathological injury. Conclusions Serum anti-CRP antibody could be used to differentiate late-onset AI-ATIN and predict relapse of ATIN at the time of renal biopsy. The CRP linear peptides PT6 and PT17 could be used as coating antigens to detect anti-CRP antibodies, which may provide more information for the clinical assessment of ATIN.
Avaliação internacional em larga escala: a participação de Portugal no TIMSS, PIRLS e ICILS

In the last few decades, the large-scale evaluation has acquired an importance in the educational field. International studies developed from surveys are increasingly numerous and cover different domains. Portugal has been participating in several studies, allowing to obtain information about the educational system and the socioeconomic context of the families and students. These data are reflected in the definition and implementation of educational policies. In this article we present an analysis of three international studies in the field of education, in which Portugal participates: Trends in International Mathematics and Science Study (TIMSS), Progress in International Reading Literacy Study (PIRLS) and the International Computer and Information Literacy Study (ICILS), carried out by International Association for the Evaluation of Educational Achievement (IEA). In this article we present an analysis of the general results of Portugal and we use an interpretative methodology, based on the analysis of reports and databases produced by different organizations, and undertaken by IEA. Despite the different fluctuations, in the different study cycles, Portuguese students have been showing positive results.
The Cycle of Kinetochore-Negative Micronuclei and Chromosome Fragments Occurred in Mitosis of Hela Cells

According to the presence of kinetochores or not, MNi are further classified into kinetochore-negative MNi (KâMNi) and kinetochore-positive MNi (K+MNi), which show the different mechanisms of micronucleus formation. However, the differences in fates of KâMNi and K+MNi have not been completely addressed. The present study aims to address these questions. Methods: Here, HeLa CENP B-GFP H2B-mCherry cells were chosen to distinguish K+MNi and KâMNi in living cells. In the cells, MNi were identified by H2B-mCherry and further classified into K+MNi and KâMNi, i.e. the K+MNi contained CENP B-GFP, while the KâMNi did not. Long-term live-cell imaging was applied in the cells to record the dynamics of cell mitosis, especially K+MNi and KâMNi. Results: Our results show that the presence of KâMN or K+MN did not result in multipolar mitosis. KâMN-bearing cells produced much more chromosome fragments than did MN-free cells. Most of the chromosome fragments eventually merged into KâMNi. K+MN-bearing cells yielded more kinetochore-positive lagging chromosomes (K+LCs) and K+MNi than MN-free cells did. Conclusion: The results suggested the differences in the fates of K+MNi and KâMNi in mitosis. The cycle of Kâ MN â Chromosome fragment â KâMN may occur in generations of KâMN-bearing cells, while part of K+MNi might reincorporate into the main nucleus.
An Efficient Far-Field Wireless Power Transfer via Field Intensity Shaping Techniques

Radiative (or far-field) energy replenishment for devices such as smartphones, laptops, robots, and small electric appliances paves the way to autonomous and continuous devices functioning, thus bypassing the need of operation interruptions, human maintenance activities, and replenishment by wired transformers. In this work, we investigate the feasibility of using a properly engineered antenna array able to deliver radiative power to devices in need of energy replenishment during their normal and unsupervised activity, whose locations are unknown. Both the case of single and multiple devices needing energy replenishment are addressed. A quantitative proof-of-concept study is carried out to validate the proposed approach. A 3D scenario is simulated to study the case of devices in need of energy replenishment within a standard office environment. Different antenna array configurations are investigated and the corresponding performances benchmarked against a standard installation of recharging antennas. Results confirm the outstanding capability of the proposed approach in terms of confinement and maximization of power transfer. Finally, in this framework, we also propose an efficient communication protocol that is able to manage multiple recharge demand given different operational rules.
Interaction laser plasma dans le régime relativiste : Application à la production de sources ultrabrèves de particules énergétiques.

This thesis is related to inertial fusion research, and particularly concerns the approach to fast ignition, which is based on the use of ultra-intense laser pulses to ignite the thermonuclear fuel. Until now, the feasibility of this scheme has not been proven and depends on many fundamental aspects of the underlying physics, which are not yet fully understood and which are also very far from controls. The main purpose of this thesis is the experimental study of transport processes in the material over-dense (solid) and under-dense (gas jet) of a beam of fast electrons produced by pulse laser at a intensity of some 1019 Wcm-2.
