Does workplace spirituality influence knowledge-sharing behavior and work engagement in work? Trust as a mediator

Management scholars view workplace spirituality as the main factor behind building trust among employees and playing a pivotal role in enhancing the organization's positive outcomes, i.e., knowledge sharing behavior & work engagement. Underpinning social exchange theory, we explored the linkage between workplace spirituality, knowledge sharing behavior, and work engagement. We further studied to look at the mediating effect of trust between workplace spirituality and positive outcomes. Data was collected from six private companies, the total number of respondents was (n=196). The study's analysis showed that workplace spirituality substantially positively impacts knowledge sharing behavior and work engagement. Furthermore, the link between workplace spirituality, knowledge sharing behavior, and work engagement is positively and statistically significantly mediated by trust. Thus, this work contributes significantly to the research paradigm by presenting workplace spirituality as a solution for high-rise trust among employees, fostering employee engagement in their work, and improving the capacity of knowledge-sharing behavior. Additionally, at the end of this study, theoretical and managerial suggestions, future avenues, and limitations are stated.
On the iterative solution of systems of the form ATA x=ATb+c

Given a full column rank matrix $A \in \mathbb{R}^{m\times n}$ ($m\geq n$), we consider a special class of linear systems of the form $A^\top Ax=A^\top b+c$ with $x, c \in \mathbb{R}^{n}$ and $b \in \mathbb{R}^{m}$. The occurrence of $c$ in the right-hand side of the equation prevents the direct application of standard methods for least squares problems. Hence, we investigate alternative solution methods that, as in the case of normal equations, take advantage of the peculiar structure of the system to avoid unstable computations, such as forming $A^\top A$ explicitly. We propose two iterative methods that are based on specific reformulations of the problem and we provide explicit closed formulas for the structured condition number related to each problem. These formula allow us to compute a more accurate estimate of the forward error than the standard one used for generic linear systems, that does not take into account the structure of the perturbations. The relevance of our estimates is shown on a set of synthetic test problems. Numerical experiments highlight both the increased robustness and accuracy of the proposed methods compared to the standard conjugate gradient method. It is also found that the new methods can compare to standard direct methods in terms of solution accuracy.
On the topological theory of Group Equivariant Non-Expansive Operators

In this thesis we aim to provide a general topological and geometrical framework for group equivariance in the machine learning context. A crucial part of this framework is a synergy between persistent homology and the theory of group actions. In our approach, instead of focusing on data, we focus on suitable operators defined on the functions that represent the data. In particular, we define group equivariant non-expansive operators (GENEOs), which are maps between function spaces endowed with the actions of groups of transformations. We investigate the topological, geometric and metric properties of the space of GENEOs. We begin by defining suitable pseudo-metrics for the function spaces, the equivariance groups, and the set of GENEOs and proving some results about our model. Basing on these pseudo-metrics, we prove that the space of GENEOs is compact and convex, under the assumption that the function spaces are compact and convex. These results provide fundamental guarantees in a machine learning perspective. We show some new methods to build different classes of GENEOs in order to populate and approximate the space of GENEOs. Moreover, we define a suitable Riemannian structure on manifolds of GENEOs making available the use of gradient descent methods.
Encapsulation of Vanadium Phosphorus Oxide into TiO2 Matrix for Selective Adsorption of Methylene Blue from Aqueous Solution

Vanadium phosphorus oxide (VPO) has been embedded in a titania matrix. The adsorption capacity of the VPO(5–30 wt %)@TiO2 composites and VPO alone for the removal of harmful cationic and anionic dyes such as methylene blue (MB), rhodamine B (RhB), and methyl orange (MO) have been extensively investigated. The FT-IR, XRD, TGA, FE-SEM, EDX, and BET techniques were applied for characterization of the adsorbents. Batch-adsorption experiments demonstrated that the VPO(30 wt %)@TiO2 as the best composite selectively removes MB with more than 94% removal efficiency. The adsorption behavior of the MB on the VPO(5–30 wt %)@TiO2 composites was investigated with variations in the mass of sorbent, initial dye concentration, solution pH, temperature, and contact time. Kinetic experiments demonstrated that the pseudo-second order kinetic model showed the best fit with the adsorption data. The efficiency of the VPO(30 wt %)@TiO2 as the preferred composite remained unchanged after five adsorption cycles, and could be reg.
Effect of the nano-titanium dioxide (nano-TiO2) coating on the photoaging properties of thermally treated bamboo

ABSTRACT Moso bamboo was firstly treated in a vacuum chamber at 150°C, 170°C, 190°C, and 210°C for 1, 2, and 3 h, respectively. Nano-TiO2 gel were then coated on the surface of thermally treated (TM) bamboo. Finally, specimens were radiated by an accelerated aging chamber of xenon lamp for 144 h. Chroma Meter, Scanning electron microscopy and Energy-dispersive spectroscopy (SEM-EDS) were applied to investigate the effect of nano-TiO2 coating on the surface color stability of TM bamboo. Results revealed that TM imposed a significant effect on the surface color of bamboo, e.g. when treatment temperature and duration increased, bamboo surface became darker. The color parameters of TM bamboo coated with nano-TiO2 gel after aging were close to the bamboo before aging, indicating that the photo-discoloration resistance of the TM bamboo has been improved. The nano-TiO2 gel with a concentration of 10% shows a better effect than that of 5%. After aging for 144 h, the ΔE of TM bamboo (190°C/2 h) coated by nano-TiO2 gel with a concentration of 10% was 2.90, which decreases by 25% compared with that of uncoated bamboo. Furthermore, the nano-TiO2 coating had no obvious aging failure after 144 h aging, which avoided the leaching of TiO2 particles during the long-term service.
How Democracy Works within a Populist Party: Candidate Selection in the Alternative for Germany

Abstract Does the demand for more direct democracy by populist parties have any implications for their internal decision-making? To answer this question, a novel large-scale research project analyses the 2017 candidate selection of all Bundestag parties, including the populist Alternative for Germany. Some 1,334 individual nominations of seven parties are compared using quantitative indicators along three dimensions of intra-party democracy (IPD): competition between aspirants for candidacy, inclusion of members and nomination-related communication. It shows that the AfD is living up to its promise of practising grassroots democracy: in all results it ranks at the top by a wide margin. A new populist organizational model seems to have emerged following neither the classic hierarchical and leader-oriented mode of many other European right-wing populist parties nor the delegate assembly mode typical of German parties. Our further development of IPD concepts, newly elaborated measuring methods and surprising empirical evidence improve the understanding of democratic decision-making in populist parties.
Determining Factors of Purchase Intention in Personalized Website Context for Indonesian Consumers

Personalized services can increase customer satisfaction, encourage emotional consumers, help consumers choose a product, and build relationships between service providers and consumers. This study combines the variables embedded in Technology Acceptance Model (TAM), Theory Planned Behavior (TPB), shopping experience, enjoyment, and trust in a research framework model, to examine factors determiningindividual purchase intentions with personalization features on online shopping sites. This study uses primary data obtained by the online survey method. The number of samples analyzed in this study is 303 e-commerce consumers in Indonesia. This study proves that consumer purchase intentions on websites with personalization are positively and significantly related to three factors: the perceived ease of use, perceived enjoyment, and trust. Furthermore, the results also show that the utilitarian value is more influential on these factors than the hedonic value. Further implications of the research results are also discussed in this paper.
Comprehensive Sexuality Education to Reduce Pregnancy and STIs in Adolescents in the United States: A Systematic Review and Meta-Analysis

Abstract The United States has a higher rate of teen pregnancy than any other developed country with 30% of American girls becoming pregnant before the age of 20. Laws regarding the inclusion and content of sexuality education vary across the country, which are associated with differences in pregnancy and sexually transmitted infection (STI) rates between states. This systematic review aims to determine whether comprehensive sexuality education (CSE) is more effective than abstinence-only or no sexuality education at reducing teenage pregnancy. Secondary objectives include analyzing the effect of CSE on STI incidence, sexual activity, safe-sex behaviors, and social discomfort. We searched multiple databases for studies published from 1990 to 2021. Twenty-nine studies met our inclusion criteria. Seven included pregnancy as an outcome, with three fitting our meta-analysis criteria. There was a decrease in pregnancy rates for participants in the CSE intervention compared to the control (n = 3, risk ratio = 0.89, 95%CI 0.79–1.00, I2 = 0%). We found that CSE is likely to reduce pregnancy rates; however, there was limited data available on this outcome. CSE increased safe-sex behaviors but did not have a notable impact on sexual activity or STIs. This review can serve as evidence for the implementation of CSE in the US.
Ighrāq and tamyīʿ (sinking and diluting): Urban electronic newspapers from celebrating freedom into designing chaos

ABSTRACT The purpose of this study is to understand the journalism practice enacted by Moroccan Urban Electronic Newspapers' (UENs) journalists and news media practitioners. This study, therefore, takes representative UENs' reporters, journalism intellectuals, and the editorial managers' perspectives on the contribution of these platforms to explore the transformative era of electronic journalism in Morocco. The participants' views regard that the digital era has widened the creation and multiplication of UENs, which has interestingly celebrated freedom of content circulation and audience outreach but engendered chaos through sinking and diluting. Hence, this has led several journalists to demand structural state intervention. As a result, journalism scholars and practitioners warn against deteriorating journalism conditions facilitated to increase practitioners” call for rigid and paternalistic supervision of the field.
Stereotyped Communication: The Ascribed Identities of Nigerians Living in the U.S.

ABSTRACT This study examined how Nigerians in the U.S. negotiate their identities considering the stereotypes ascribed to them during interactions and strategies for attenuating stereotypes. Interviews with 20 Nigerians revealed that Nigerians were stereotyped positively (i.e., as hardworking, and passionate for education) and negatively (i.e., as fraudsters, kidnappers, and underdeveloped). Also, Nigerians attenuated stereotypes ascribed not only to Nigerians but to Blacks through nationalism, self-awareness, and hard work. Findings challenge beliefs that stereotyping occurs due to the lack of contact with outgroup members. Indeed, stereotyping occurs because of some form of history rather than an absence of history with outgroup members.
Pulling back singularities of codimension one objects

We prove that the preimage of a germ of a singular analytic hypersurface under a germ of a finite holomorphic map $g: (\mathbb{C}^n,0) \rightarrow (\mathbb{C}^n,0)$ is again singular. This provides a generalization of previous results of this nature by Ebenfelt-Rothschild [Comm. Anal. Geom. 15 (2007), no. 2, 491-507], Lebl [arXiv:0812.2498], and Denkowski [Manuscripta Math. 149 (2016), no. 1-2, 83-91]. The same statement is proved for pullbacks of singular codimension one holomorphic foliations.
Methane Emissions Offset Net Carbon Dioxide Uptake From an Alpine Peatland on the Eastern Qinghai‐Tibetan Plateau

Peatlands store large amounts of carbon (C) and actively exchange greenhouse gases (GHGs) with the atmosphere, thus significantly affecting global C cycle and climate. Large uncertainty exists in C and GHG estimates of the alpine peatlands on Qinghai‐Tibetan Plateau (QTP), as direct measurements of CO2 and CH4 fluxes are scarce in this region. In this study, we provided 32‐month CO2 and CH4 fluxes measured using the eddy covariance (EC) technique in a typical alpine peatland on the eastern QTP to estimate the net C and CO2 equivalent (CO2‐eq) fluxes and investigate their environmental controls. Our results showed that the mean annual CO2 and CH4 fluxes were −68 ± 8 g CO2‐C m−2 yr−1 and 35 ± 0.3 g CH4‐C m−2 yr−1, respectively. While considering the traditional and sustained global warming potentials of CH4 over the 100‐year timescale, the peatland acted as a net CO2‐eq source (1,059 ± 30 and 1,853 ± 31 g CO2‐eq m−2 yr−1, respectively). The net CO2‐eq emissions during the non‐growing seasons contributed to over 40% of the annual CO2‐eq budgets. We further found that net CO2‐eq flux was primarily influenced by global radiation and soil temperature variations. This study was the first assessment to quantify the net CO2‐eq flux of the alpine peatland in the QTP region using EC measurements. Our study highlights that CH4 emissions from the alpine peatlands can largely offset the net cooling effect of CO2 uptake and future climate changes such as global warming might further enhance their potential warming effect.
Environmentalism among poor and rich countries: using natural language processing to handle perfunctory support and rising powers

Abstract In international politics, is environmental protection largely a “rich-country” priority? We perceive four reasons why, although individual exceptions are possible, the answer would be yes: as a country meets more of its basic economic needs, it can better take on environmental policy’s long-term thinking, policy expenses, collective action problems, and quality-of-life issues. To cut through lip service paid by governments that are not serious about environmental protection, and the fact that the “BASIC” countries (Brazil, South Africa, India, China) occupy a gray area between rich and poor, we employ computer-assisted textual analyses on all 3,774 paragraphs of statements made by national governments between 1995–2012 in the Committee on Trade and Environment (CTE) within the World Trade Organization (WTO). Controlling for other factors, we find a general pattern of environmental discussions increasing as development level increases. This contributes substantively and methodologically to the literatures on the environment/development nexus and rising powers.
Impact of the wind field at the complex terrain site Perdigão on the surface pressure fluctuations of a wind turbine

Abstract. The influence of turbulent inflow, as it occurs in complex terrain, on the unsteady surface pressure distributions on a wind turbine is investigated numerically. A method is presented that enables an accurate reproduction of the inflow to the turbine in the complex terrain in Perdigao, Portugal. For this purpose, a precursor simulation with the steady-state atmospheric computational fluid dynamics (CFD) code E-Wind and a high-resolution Delayed Detached Eddy Simulation (DDES) with FLOWer is performed. The conservation of the flow field is validated by a comparison with measurements from the 2017 field campaign in Perdigao. Then, the resolved fluid-structure coupled generic wind turbine I82 is included in the FLOWer simulation to investigate the impact of the complex terrain inflow on the surface pressure fluctuations on tower and blades. A comparison with simulations of the same turbine in flat terrain with simpler inflows shows that the turbine in complex terrain has a significantly different vortex shedding at the tower, which dominates the periodic pressure fluctuations at the tower sides and back. However, the dominant source of periodic pressure fluctuations on the upper part of the tower, the blade-tower interaction, is hardly altered by the terrain flow. The pressure fluctuations on the blade have a rather broadband characteristic, caused by the interaction of the leading edge with the inflow turbulence. In general, it is shown that a sophisticated DDES of the complex terrain plays a decisive role in the unsteady aerodynamics of the turbine, due to its specific flow characteristic.
A review on the phytochemistry and pharmacology of the herb Scoparia dulcis L. for the potential treatment of metabolic syndrome

This review discusses the chemical constituents and pharmacological effects of Scoparia dulcis L. (S. dulcis) plants. So far, approximately 160 compounds have been identified from S. dulcis, among which 115 compounds may be related to the treatment of metabolic syndrome. Extracts of S. dulcis have effects of reducing fasting blood glucose level, increasing the plasma insulin level, and stimulating insulin secretion to treat diabetes. They also produce antihyperlipidemic effects by increasing serum high-density lipoprotein levels, the anti-atherogenic index of plasma, and HMG-CoA reductase activity. The chemical composition of glutinol and glutinone, isolated from S. dulcis, provide potential anti-inflammatory effects. These compounds can also reduce total cholesterol, triacylglycerol, and low-density lipoprotein (LDL)-cholesterol and increase high-density lipoprotein (HDL)-cholesterol to provide the anti-atherosclerotic effect. S. dulcis exerts anti-arthritic properties through its effect on cytokine levels, significantly reducing IFN-γ and IL-6 levels and elevating IL-10 levels. The extracts carry out hepatoprotective effect by preventing the descent of the antioxidative enzymes of superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GRd), and glutathione-S-transferase (GST). Therefore, S. dulcis provides new potential for medicine given its numerous therapeutic properties and can be promoted as a complementary or alternative therapy for patients with chronic conditions.
Using a Cross-Classified Multilevel Mediation Model (CC-M3) with Longitudinal Data Having Changes in Cluster Membership

ABSTRACT Cluster memberships associated with the mediation effect are often changed due to the temporal distance between the cause-and-effect variables in longitudinal data. Nevertheless, current practices in multilevel mediation analysis mostly assume a purely hierarchical data structure. A Monte Carlo simulation study is conducted to examine the consequence of ignoring the changes in cluster memberships in multilevel mediation analysis. Results show that the proposed method, Cross-Classified Multilevel Mediation Model (CC-M3), outperforms the conventional multilevel model with substantially smaller relative biases in parameter estimates (about 50% less) and a more consistent and higher coverage rate. Findings of this simulation study inform the empirical researchers that the changes in cluster-membership needs to be appropriately taken into consideration in mediation analysis. We demonstrate the use of CC-M3 in the applied example.
Prognostic and tumor-immune infiltration cell signatures in tamoxifen-resistant breast cancers.

Background The cumulative risk of distant recurrence of hormone receptor-positive (HR+) breast cancer in the past 20 years has ranged from 22% to 52% after 5 years of endo-therapy. The TNM stage, histological grade, and age are important clinical factors related to recurrence, however the exact mechanism of tamoxifen resistance is still unclear. Methods Differentially expressed genes (DEGs) were identified in 10 pairs of patients who had relapsed and non-relapsed after tamoxifen treatment based on matching their clinicopathological factors. After analysis of the Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, 10 hub genes were identified using Cytoscape software. Next, real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) database were used to verify the expression and overall survival (OS) of the 10 hub genes respectively, and GSE96058 and Kaplan-Meier Plotter website were used to further verify the OS of C3, CX3CL1, CXCL2, and SAA1. Finally, Immune Cell Abundance Identifier (ImmuCellAI) and the TIMER database were used to estimate immune cell infiltration and the expression of prognostic genes. Results The DEGs were mainly enriched in the inflammatory response and cytokine-receptor interaction. The expression and the survival analysis identified CX3CL1, CXCL2, and SAA1 as prognostic factors, whose overexpression in HR+/human epidermal growth factor receptor 2 (HER-2) negative breast cancer possibly predicted a longer disease-free survival. The expression levels of these 3 genes are positively correlated with immune cell infiltration. Their high expression levels may predict longer disease-free survival in breast cancer after tamoxifen treatment and may be biomarkers for tamoxifen-resistant therapy. Conclusions In conclusion, the high expression of CX3CL1, CXCL2, and SAA1 may predict longer disease-free survival in breast cancer after tamoxifen treatment and may be a biomarker for tamoxifen therapy.
The Fundamental Plane of cluster spheroidal galaxies at z ∼ 1.3: evidence for mass-dependent evolution

We present spectroscopic observations obtained at the Large Binocular Telescope in the field of the cluster XLSSJ0223−0436 at z = 1.22. We confirm 12 spheroids cluster members and determine stellar velocity dispersion for 7 of them. We combine these data with those in the literature for clusters RXJ0848+4453 at z = 1.27 (8 galaxies) and XMMJ2235−2557 at z = 1.39 (7 galaxies) to determine the Fundamental Plane (FP) of cluster spheroids. We find that the FP at z ∼ 1.3 is offset and rotated (∼3σ) with respect to the local FP. The offset corresponds to a mean evolution Δlog(Mdyn/LB) = (−0.5 ± 0.1)z. High-redshift galaxies follow a steeper mass-dependent Mdyn/LB–Mdyn relation than local ones. Assuming Δ log(Mdyn/LB) = Δ log(M*/LB), higher mass galaxies [log(Mdyn/M⊙) ≥ 11.5] have a higher formation redshift (zf ≥ 6.5) than lower mass ones [zf ≤2 for log(Mdyn/M⊙ ≤ 10)], with a median zf ≃ 2.5 for the whole sample. Also, galaxies with higher stellar mass density host stellar populations formed earlier than those in lower density galaxies. At fixed initial mass function, Mdyn/M* varies systematically with mass and mass density. It follows that the evolution of the stellar populations (M*/LB) accounts for the observed evolution of Mdyn/LB for Mdyn > 1011 M⊙ galaxies, while accounts for ∼85 per cent of the evolution at Mdyn < 1011 M⊙. We find no evidence in favour of structural evolution of individual galaxies, while we find evidences that spheroids later added to the population may account for the observed discrepancy between Δlog(Mdyn/LB) and Δ log(M*/LB) at masses <1011 M⊙. Thus, the evolution of the FP of cluster spheroids is consistent with the mass-dependent and mass density-dependent evolution of their stellar populations superimposed to a minor contribution of spheroids joining the population at later times.
