Stronger Together: Conditional Indirect Effect of Servant Leadership on Transactive Memory Systems

The leadership literature suggests that followers are likely to be autonomously motivated when working for servant leaders, leading them to experience greater psychological empowerment. Guided by self-determination theory, we predicted that this empowerment would then heighten individuals’ perceptions of their teams’ transactive memory systems. When subordinates perceive that discrimination is occurring in their workgroup, however, we expected that the empowerment—transactive memory systems link would be weakened. This moderated mediation model was tested at multiple timepoints using 211 employees from a variety of industries and job types. The results generally supported our predictions, and the implications for theory and practice are discussed.
World Café Method: the Possibility of Understanding Active Methodologies in Remote Learning

The great challenge in these last decades in education is the growing search for innovative teaching methodologies that enable a pedagogical praxis able to form subjects with ethical, historical, critical, reflective, transformative and humanized profile. The present study stems from the following problematization: what is the contribution of the active teaching methodology called “World Café” in teaching and learning processes, so that it favors teaching innovation in remote learning during the COVID-19 pandemic? In facing this problem, the following objectives were listed: a) understanding the contributions of the World Café Method in teaching and learning process innovation; b) analyze the viability of the World Café Method in remote learning. A quali-quantitative, descriptive and applied methodological strategy is employed, drawing on Barbosa (2013), Berbel (2011), Brown and Isaacs (2007), Minayo (2010), Moran (2014) and Triviños (1987). The data were analyzed using discourse analysis techniques (Bardin, 2016). We conclude that it is possible to use the World Café Method in virtual, remote learning, as it enables the promotion of ideas, discussions, reflections, questions, and engages participants, that is, a collective learning process.
Sideband intensities in NMR spectra of samples spinning at the magic angle

General integral and series expressions are derived for the intensities of sidebands observed in the magic angle spectra of inhomogeneously broadened I=1/2 systems. The expressions are evaluated for a wide range of shift parameters and the results used to construct graphical and numerical methods for extracting the principal values of chemical shift tensors from the intensities of just a few sidebands. The methods are illustrated by application to 31P spectra of barium diethyl phosphate. The results agree well with previous single crystal measurements.
Health assessment for piston pump based on Laplacian eigenmaps-random forests method

A piston pump is one of the key components in a hydraulic system. Therefore, a failure may severely hurt the reliability of the hydraulic system and cause great loss. Currently, how to effectively evaluate the health condition of the piston pump remains an open problem. In this paper, a novel health assessment method based on an integration of Laplacian eigenmaps and random forests is proposed, which takes full advantage of both the fusion ability of correlated features enabled by the Laplacian eigenmaps and the optimized feature-selection ability provided by the random forest. The proposed method (LE-RF) is applied to piston pumps for validation. The results indicate that the Laplacian eigenmaps-random forest (LE-RF) technique can provide an effective tool for piston pump health condition assessment. Compare with other manifold methods, e.g., LLE and ISOMAP and classification method of KNN, the LE-RF method can achieve better and more accurate assessment results.
Stability and Stabilization Condition for T-S Fuzzy Systems with Time-Delay under Imperfect Premise Matching via an Integral Inequality

This paper focuses on the stability and stabilization analysis for the T-S fuzzy systems with time-delay under imperfect premise matching, in which the number of fuzzy rules and membership functions employed for the fuzzy model and fuzzy controller are different. By introducing an augmented Lyapunov-Krasovskii function containing a triple-integral term, a less conservative membership-dependent stability condition is proposed via an integral inequality. Moreover, a new design approach under imperfect premise matching is developed in the paper. Four numerical examples are given to illustrate the advantages of our approaches. A practical benchmark problem namely continuous Stirred Tank Reactor (CSTR) is discussed in details in order to further verify their effectiveness.
Carrier injection in semiconductors with position‐dependent band structure: Electron‐beam‐induced current at heterojunctions

We present simulations of external carrier injection in semiconductors with position‐dependent band structure by numerical solution of the current transport equations across the device. As a model case, we examine electron‐beam‐induced current at heterojunctions. Our treatment is applicable to an arbitrary position‐dependent band structure, and any form of external generation, and allows for an external bias applied to the device. The quality of ohmic contacts is taken account of by realistic boundary conditions. For excitation by an electron beam at a GaAs/AlGaAs n‐N isotype heterojunction, we present band profiles, as well as linescans, of electron‐beam‐induced current and voltage. The influence of external generation rate, interface grading, and contact quality is investigated. The latter is shown to be important in epitaxial layers which are only a few minority‐carrier diffusion lengths thick. The saturation behavior of the signal with increasing injection level is studied as a function of device para.
Programa para desarrollar el desapego en los cuidadores de perros guías

With the present research project for the development of detachment in the caregivers of guide dogs, we want to pay tribute to all the caregivers who voluntarily perform such a commendable and necessary action for blind people. We want to approach the process of attachment and detachment from a different emotional regulation perspective. Through in-depth interviews with a qualitative sample of 3 guide dog handlers who currently perform this function, we dive into their daily lives, knowing first-hand the situations, emotions and resistance they encounter in this process. With the help of bibliographic references from psychoanalysts, psychiatrists and professionals in these areas, we have been able to demonstrate certain behavioral traits and emotional states that impact on the affective bond of human beings with dogs.
The Development and Psychometric Properties of the Polish Version of the Self-Control Scale

Samokontrola jest ważną funkcją ludzkiego Ja, dzięki której osoba może przezwyciężyć lub zmienić swoje impulsy, nastroje, emocje i zachowania. Tangney, Baumeister i Boone opracowali skalę do pomiaru indywidualnych różnic w samokontroli – Skalę Samokontroli (Self-Control Scale, S-CS). W artykule przedstawiono adaptację S-CS do polskich warunków kulturowych, nad którą prace rozpoczęto, gdy nie było metody pomiaru samokontroli w Polsce. Cele niniejszego badania były następujące: 1) opracowanie polskiej wersji Skali Samokontroli (S-CS-Pv); 2) ocena właściwości pozycji testowych SC-S-Pv; 3) oszacowanie rzetelności SC-S-Pv; 4) porównanie wewnętrznej struktury S-CS-Pv z oryginalną skalą; 5) ocena trafności teoretycznej SC-S-Pv. W procesie adaptacji S-CS zastosowano procedurę tłumaczenia zwrotnego. Polska adaptacja jest rzetelną metodą o trafności wykazanej zarówno przez korelację z innymi testami, jak i przez porównania grup. Wyniki analizy czynnikowej sugerują jednak jej strukturę wielowymiarową.
Adaptive Force-field Control of a 2-DOF Upper-extremity Rehabilitation Robot

Introduction For the last twenty years, rehabilitation robots have been in development to augment conventional therapy methods. Robot-assisted therapy can provide stroke survivors with repetitive tasks while delivering measured therapy that is able to objectively evaluate patients' progress [1]. An important control design criterion for rehabilitation robots is finding the best motion to maximize the effectiveness of rehabilitation [2].
Are Australian speech-language therapists working in the literacy domain with children and adolescents? If not, why not?

A cross-sectional online survey was completed by 219 speech-language therapists (SLTs) to explore their views and practices when working with children and adolescents who have literacy difficulties. They were recruited via 11 workshops hosted by Speech Pathology Australia, held across Australia and completed the survey prior to attending their respective workshop. Participants reported overwhelming support for SLTs to work with students struggling to learn literacy and supported not only a role for SLTs to work with children in the preschool years to promote readiness to learn to read at school, but also a role for services to students beyond the early years of school. While SLTs valued specific clinical and collaborative activities, a significant gap was found between their perceived feasibility of those activities and their perceived value. Results show SLTs are less confident providing written support to students than they are in providing phonological awareness and vocabulary interventions. While SLTs clearly value their role in the literacy domain, this study highlights evident gaps in preservice training in this area, as well as a need for improved SLT and teacher knowledge exchange, and collaboration in supporting children and adolescents with literacy difficulties.
Soil Quality Assessment Based on a Minimum Data Set: A Case Study of a County in the Typical River Delta Wetlands

Purpose: The Yellow River delta boasts rich land resources but lacks fresh water and exhibits poor natural conditions. To rationally develop and utilize the land resources therein, it is necessary to evaluate the soil quality. Methods: Adopting specific screening conditions, principal component analysis (PCA) was used to construct a minimum data set (MDS) from 10 soil indicators. Then, a complete soil quality evaluation index system of the Yellow River delta was developed. The soil quality comprehensive index (SQI) method was used to assess the soil quality in the Kenli District, and the soil quality grades and spatial distribution were analyzed. Results: (1) The average SQI of the Kenli District is 0.523, and the best soil quality is concentrated near the Yellow River, especially in Huanghekou town. (2) The normalized difference vegetation index was positively correlate with SQI, whereas Dr (nearest distance between the sampling site and Yellow River) and Ds (nearest distance between the sampling site and Bohai Sea) were negatively correlated with SQI. Elev (sampling site elevation) was not correlated with SQI. (3) The SQI of agricultural planting is greater than that of the natural land type and significantly greater than that of nudation. The main factors limiting farmland soil quality are SK (water-soluble potassium) and pH, whereas the factor limiting the natural land type are the soil nutrient indicators. Conclusions: To improve soil quality and develop and utilize land resources, the towns should adopt systematic land development/utilization methods based on local conditions. These results have important guiding significance and practical value for the more objective and accurate evaluation of soil quality in coastal areas and the development and utilization of land resources.
Competing through manufacturing: countering a product's liability of foreignness through mass customization

PurposeThe operational capability of mass customization (MC) allows consumers to obtain products tailored to their idiosyncratic needs. This study aims to provide insights into the potential of this capability for countering a product's liability of foreignness – the negative effect of the out-group status of a product's country of origin (COO) on consumers' evaluations of the product.Design/methodology/approachBased on the social identity approach, it is hypothesized that this liability is reduced when a consumer product is mass-customized rather than standardized as per a mass-production strategy. This hypothesis is tested using a mixed between- and within-subject experiment.FindingsWhen evaluating mass-produced sneakers, native German-speaking (Italian-speaking) South Tyrolean consumers rated the quality of Italian (German) sneakers significantly lower than that of German (Italian) sneakers. However, when the sneakers were mass-customized, this difference in perceived product quality was non-significant for both groups of consumers, supporting the research hypothesis.Research limitations/implicationsFuture research could replicate this study in other samples, with other product types, COOs and countries of destination, as well as at different degrees of product customization.Practical implicationsBusiness-to-consumer firms contemplating the development of their MC capability are made aware that the benefits of this operational capability might go beyond the typical advantages highlighted by the existing literature.Originality/valueThis paper joins the discussion on MC value by offering a theoretical explanation and empirical support for another mechanism through which the operational capability of MC can create value, at least in business-to-consumer industries: by countering a product's possible liability of foreignness and thus increasing perceived product quality in export markets.

The physiological response of cut carnation flowers to ethanol and acetaldehyde post-harvest treatments.

A replacement for silver thiosulphate as a commercial post-harvest treatment needs to be found. The longevity of cut carnation flowers is extended by all concentrations of ethanol tested. Compared to a water control, the vase-life of ethanol-treated flowers is between 150 and 250% longer. The greatest longevity increases are recorded with 3% ethanol. The use of ethanol as a post-harvest treatment was tested. The longevity increase as a result of ethanol application only occurs if the ethanol is applied as a holding solution. Pulse treatments are not effective at delaying the senescence of the flowers. The sooner the ethanol is , . t applied, the greater the increase in vase life. If ethanol treatment is halted at any point during the experiment, the longevity of the flowers is reduced. It was observed that the longer the stems of ethanol-treated flowers, the greater the longevity increases. The ethanol holding solution does not prevent the action of external ethylene, thereby restricting the potential of ethanol as a commercial post-harvest treatment. Physiologically, flowers treated with ethanol exhibit a different senescence process to control flowers. The typical in-rolling of the petals of carnation flowers is not seen, instead the petals appear burnt. The 'ovaries are also notably effected by ethanol, being smaller and more yellow in colour. Ethanol treatment results in longevity increases by inhibiting the formation of ethylene, the plant hormone responsible for senescence. The concentration of the direct precursor to ethylene, ACC, as well as the activity of the enzyme that converts ACC to ethylene, ACC oxidase, is reduced to almost zero in the tissues of treated flowers.

Reactions of gas-phase atomic metal ions with the macrocyclic ligand tribenzocyclotriyne

Reactions of 22 atomic metal cations with the macrocyclic molecule tribenzocyclotriyne (TBC) were studied in the gas phase in the Fourier-transform ion cyclotron resonance spectrometer. Most of the ions underwent association with TBC with good collisional efficiency to give M(TBC) + , with the exceptions of Zn + and Au + , for which the highly exothermic charge-transfer reaction dominated, and Cs + , which was unreactive. Most of the M(TBC) + ions attached a second ligand to give M(TBC) 2+ , presumably the sandwich complex
Sex Differences in Ventilation amongst Athletes Undergoing EVH Challenge Testing for Exercise-Induced Bronchoconstriction

We aimed to report sex differences in ventilation during EVH challenge in University athletes while exploring whether they achieve inspiratory target. Seventy-seven athletes (n = 42 males, n = 35 females) performed six-minute EVH chal lenge involving compressed gas (5% CO 2 , 21% O 2 and balance N 2 ) inhalation at an inspiratory target of 85% MVV indirect . Ventilation was recorded every 15 seconds during EVH challenge with pre-and post-challenge measurements of FEV 1 determining outcomes. Males reached significantly higher ventilation (412.0 ± 55.0 L) compared with female athletes (292.5 ± 43.2 L), (F = 3890.0, p < 0.05), and a significant effect of time (F (23) = 3689.8, p < 0.05) as well as interaction (F = 106.3, p < 0.05) was noted. There were significant differences in cumulative ventilation attained (679.5 ± 146.6 L) during the 6-min EVH compared with inspiratory target (807.0 ± 169.6 L), amongst both sexes (t (76) = 5.0, p < 0.05) as well as EIB positive and negative groups (p < 0.05). The results support sex differences in ventilation achievement and suggest EVH inspiratory target of 85% MVV indirect is generally not reached by athletes, thereby requiring re-evaluation and further exploration of sex differences in future EVH studies.
Heme Acquisition by trypanosomatids: Evaluation of the hemedependent behavior and its biochemical implications

The inability of some species to produce porphyrin-like compounds induces these species to search for blood to fulfill their heme requirement. The biological cycle of very relevant parasites, such as Leishmania sp. and Trypanossoma sp. , is directly related to the search for heme. The understanding of this process in a chemical and biochemical approach is a pre-requisite to obtaining advancements regarding hemoprotein structureactivity relationships as well as molecular aspects of various pathological/physiological mechanisms associated with parasitary and/or blood diseases, between others. The present work presents an overview of the chemical/biochemical properties of porphyrin, heme, heme proteins, and parasitary diseases caused by Trypanossomatidae. We believe that this kind of discussion can contribute significantly to improve the understanding of the structure-function relation of these complex diseases.
The Nature Of Firm’s Internal Environment Capabilities And Competencies Dynamics Evaluation: Feasible Strategy Crafting Imperatives

The study strategically evaluated the nature of firm’s internal environment capabilities and competencies dynamics that will ensure feasible strategy crafting. The understanding and analysis of the challenges posed in the internal environment helps strategists to make strategic decisions relating to the resources, capabilities and core competencies since they are non routine. In order to facilitate the development and effective usage of core competencies, managers/strategists are advised to have courage, self-confidence, integrity, the capacity to deal with uncertainty and complexity, and a willingness to hold people accountable for their work, as well as their being accountable themselves. This should be necessitated because the competitive advantage and firm’s performance are often strongly related to the resources firms hold and how they are managed. This is found to be so, since human beings are strategic critical resource that produces innovation, develops policies and strategies, and firm’s competitive advantage enhancement. The study further explored some related perspectives of valuable capabilities, personnel and organizational competencies, resources tangibility and intangibility, as well as competitive advantage sustainability criteria that will guide feasible strategy crafting. The study recommends amongst others, that organization managers should as a matter of necessity, monitor and evaluate the internal environment capabilities and competencies in order to have fit with that of external resources dynamics to enhance feasible strategy crafting.
Sorption of Methylene Blue for Studying the Specific Surface Properties of Biomass Carbohydrates

The surface area is an important parameter in setting any biorefining technology. The aim of this study was to investigate the applicability of sorption of methylene blue to characterize the surface of the main biomass carbohydrates: α-cellulose, sigmacell cellulose, natural gum, β-glucan, and starch. The morphology of particles of the model objects was studied by scanning electron microscopy. Nitrogen adsorption isotherms demonstrate that the selected carbohydrates are macroporous adsorbents. The monolayer capacities, the energy constants of the Brunauer–Emmett–Teller (BET) equation, and specific surface areas were calculated using the BET theory, the comparative method proposed by Gregg and Sing, and the Harkins–Jura method. The method of methylene blue sorption onto biomass carbohydrates was adapted and mastered. It was demonstrated that sorption of methylene blue proceeds successfully in ethanol, thus facilitating surface characterization for carbohydrates that are either soluble in water or regain water. It was found that the methylene blue sorption values correlate with specific surface area determined by nitrogen adsorption/desorption and calculated from the granulometric data. As a result of electrostatic attraction, the presence of ion-exchanged groups on the analyte surface has a stronger effect on binding of methylene blue than the surface area does. Sorption of methylene blue can be used in addition to gas adsorption/desorption to assess the accessibility of carbohydrate surface for binding large molecules.
Probing the Double Bond and Phase Properties of Natural Lipid Dispersions by Cross Polarization/Magic Angle Spinning 13C NMR

Solid-state high resolution 13C NMR spectra of bovine brain sulfatide, egg sphingomyelin, egg phosphatidylcholine, and cholesterol/phosphatidylcholine dispersions were obtained by the cross-polarization/magic angle spinning (CP/MAS) method as functions of contact time, temperature and composition. Quantitative analysis of the chemical shift and linewidth data indicate that in the liquid-crystalline state the hydrocarbon chains of sulfatide are packed less orderly than those of sphingomyelin, and that there are two or more conformers for the ceramide residues of natural sphingolipids. The fatty acid double bond showed higher mobility than that of sphingosine as monitored by the signal intensity profiles as a function of contact time. The same approach was used to study the coexisting Lα (liquid-crystalline phase) and β (cholesterol-rich characterized phase) two-phase region of cholesterol/phosphatidylcholine mixtures. Without isotope enrichment, structural and phase properties of natural lipid dispersions can be obtained easily by monitoring the chemical shift, the signal intensity and the linewidth of l3C NMR spectra.
Equity Volatility and Leverage – Loan Level Evidence

This paper is the first to use loan level data to investigate the relationship between equity volatility and financial leverage on the firm level. We use a comprehensive dataset of large syndicated loans with a total loan amount in excess of 12 trillion USD. This allows us to precisely identify when a company experiences a large change in leverage. In contrast to several previous studies that have relied only on accounting data, we find very clear results that increased financial leverage increases equity volatility. Our findings are robust to controlling for time trends in variance as well as the type and purpose of the loan.
