I’m Working Hard, but It’s Hardly Working: The Consequences of Motivating Employee Effort That Fails to Achieve Performance Targets
Authors: Holderness D. Kip , Olsen Kari Joseph , Thornock Todd A.
Published: October 2023

Managers often encourage employee effort by incentivizing employees to achieve performance targets. This paper examines the effect of employee effort on counterproductive work behaviors when those employees ultimately fail to meet specified performance targets. We conduct an experiment in which participants receive a bonus for meeting a challenging performance target in a real-effort task. We find that for individuals who fail to meet the performance target, greater effort is correlated with both an increased propensity toward noncompliant behavior and an increase in misreporting. Our results identify potential drawbacks of incentivizing employee effort when that effort may not translate into greater performance outcomes.

Published: October 2023

Background: Breast cancer (BC) is the most common type of malignancy among females worldwide. It is the main contributor to female cancer-related mortality and disability. The most common kind of cancer in women in Saudi Arabia is BC. A few studies have been conducted to address BC awareness, risk factors, and screening. The purpose of the current study is to evaluate the level of awareness of BC screening and risk factors among females in Saudi Arabia.
Methods: This study will be a cross-sectional study, targeting adult females in Riyadh city. In July and August 2023, data will be collected through a paper-based questionnaire scoring. In a sample of 300 females, data will be analyzed using Statistical Package for the Social Sciences.
Results: A total of 308 females completed the questionnaire. The majority of participants (45.8) were 40 years old and above and most were primary, middle, or high school (43.8) education level. Healthcare providers (19.2) and housewives (16.6) were the major participants regarding occupation. The majority of participants (75.6) were Saudi and (43.5) were from the central region. More than half of the women (56.2) were married. Most of the participants had no family history of BC (56.8%) and had no personal history of breast lump (63.6%). The majority were not diagnosed with BC (61.7%). The most reported risk factor was exposure to high doses of radiation (52.9) followed by family history (45.1) and personal history. Regarding the knowledge of screening methods, breast self-examination (BSE) was the most familiar method (57.1%), followed by mammography (56.8%) and clinical breast exam (52.3%). Out of the 308 participants, 42.86% have poor knowledge about screening for BC. Among demographic characteristics, age, and education level were significantly associated with the knowledge of screening (0.001). There was statistical significance between nationality and knowledge of screening (0.005). There was statistical significance between the region and knowledge of screening (0.001), and there was statistical significance between the occupation and knowledge of screening (0.037).
Conclusion: The study found that females have insufficient general understanding of BC. These data indicate the need for immediate initiatives to increase female knowledge of BC and BSE.

Authors: Servadio Simone , Simha Nihal , Gusmini Davide , Jang Daniel , St. Francis Theodore , D’Ambrosio Andrea , Lavezzi Giovanni , Linares Richard
Published: October 2023

The first step of any active debris removal (ADR) mission is the selection of the target. The optimal choice is to find the most dangerous debris that can be removed considering the chaser spacecraft requirements and mission constraints. After creating a catalog of the current space population in low Earth orbit (LEO), the MIT Monte Carlo Orbital Capacity Assessment Tool (MOCAT-MC) is used to simulate and predict the future space environment and the interaction among the space population. A novel performance index to quantify the criticality of each debris and the risk that it presents to the space environment is proposed. The new risk index considers the proximity of the debris to highly populated regions, its persistence in orbit, its likelihood to collide, and the estimated number and mass of debris that it can generate. The risk index is then optimized to work either with the full space population or a subset of it, where the ranking of risk among debris is highlighted. Multiple risk analyses are proposed in the test cases, where the ranked list of optimal targets is provided.
Investigating the Chemical Stability of Electrospray Plumes During Particle Collisions
Authors: Bendimerad Rafid , Tahsin Abu Taqui Md , Yonas Adam , Colucci Caleb , Petro Elaine M.
Published: October 2023

Electrospray thrusters fulfill the main propulsion requirements for long-term small-satellite missions. However, the molecules present in the plume are susceptible to collisions, chemical reactions, and fragmentation, which may introduce different new species with various mass-to-charge ratios inside the plume. Prediction of the byproducts that appear upon collisions is of prime importance to predicting the evolution of the plume and estimating the performance and the lifetime expectancy of the thruster. In this work, we use molecular dynamics simulations to investigate monomer–neutral collisions at different impact configurations, impact energies, and impact parameters, and we provide the mass spectra of the resulting species. We predict that 1) collisions within a center-of-mass distance of 6 Å can result in momentum exchange and molecular fragmentation, 2) higher-energy impacts produce more byproducts, and 3) heavy molecules (e.g., 1-ethyl-3-methylimidazolium [EMI] and [Formula: see text]) are more likely to result from weak collisions ([Formula: see text]), whereas light molecules (e.g., H, F, and [Formula: see text]) are more likely to result from strong collisions. Collisional fragmentation is shown to negatively affect key performance indicators, including reductions in thrust, specific impulse, and propulsive efficiency. This phenomenon potentially accounts for the observed discrepancies in experimental measurements of current and mass loss rates.

Published: October 2023

Incorrect formalization of original systems when creating a mathematical model can lead to useless multi-cost work and, moreover, to false conclusions. These models can not be improved by using more general properties or more complicated tools. In this article, we discuss ways of creation of adequate models for decentralized type complex systems containing various active elements with their own interests an sets of actions. We specify some basic properties of systems that correspond to certain classes of mathematical models. This approach can serve as a basis for preliminary selection of suitable models for real systems

Introduction. Chronic wounds represent a significant burden to the health care system and patients. Objective. This study determined the effectiveness of a wound scaffold comprised of PCMP for use in nonhealing, cutaneous wounds; this study analyzes pooled data from the population of 3 combined registries. Materials and Methods. A total of 3 combined registry populations were pooled from a single-center study of 41 patients, a single-center study of 86 patients, and the RESPOND Registry of 307 patients treated at 28 centers. All 434 patients received PCMP and were followed for up to 48 weeks. Male and female patients 18 years or older with wounds between 0.2 cm2 and 200 cm2 were included. Results. In total, there were 95 VLUs, 78 DFUs, 90 PIs, 73 PSWs, and 98 wounds of other etiologies analyzed. The mean baseline area, depth, and volume of all 434 wounds was 15.1 cm2, 4.9 mm, and 7.2 cm3, respectively. K-M median time to wound closure for all wounds was 19 weeks. At weeks 20, 24, 28, and 48, the frequency of wound closure for all wounds was 51%, 56%, 62%, and 72%, respectively. The median time to closure by wound type was 22 weeks for VLUs, 24 weeks for DFUs, 23 weeks for PIs, 12 weeks for PSWs, and 14 weeks for other wounds. The proportion of wounds closed were 72% (VLUs), 52% (DFUs), 63% (PIs), 95% (PSWs), and 67% (other etiologies). Conclusions.

Clinical Management of Nonuremic Calcific Arteriolopathy: A Report of Three Cases
Authors: Swoboda Laura
Published: October 2023

Introduction. Calcific arteriolopathy involves the deposition of insoluble calcium salts in the vasculature and soft tissues, leading to ischemia, thrombosis, and cutaneous necrosis. Calcific arteriolopathy is commonly associated with ESRD but can also occur outside of ESRD, known as NUC. Objective. This article reviews the clinical management and outcomes of 3 cases of non-uremic calcific arteriolopathy. Materials and Methods. This case series describes the clinical presentation and successful treatment of NUC in a community hospital–based outpatient wound center in southeastern Wisconsin. Factors presumed to be involved included chronic kidney disease–associated mineral bone disorder, dysregulation and deficiencies of the inhibitors of vascular calcifications, autoimmune dysfunction, and chronic inflammation. All 3 patients received multimodal treatment with wound hygiene, pain management, and infection control. In addition to these interventions, case 2 received NLFU. Results. All 3 patients displayed increased tolerance of compression and debridement and successfully epithelialized with no discernible effect on long-term function or quality of life. Wound infection occurred in each case. The mean overall healing time was 20 weeks. Conclusion. The study findings suggest that successful management of NUC can be achieved using IV STS, early and aggressive infection treatment, pain control, and wound hygiene. In patients with NUC, NLFU may be an appropriate adjunct to expedite healing.

We present the generation of exciton-polaritons in CdSe nanoplatelets (NPLs) at room temperature in a metal-dielectric hybrid cavity. The optical cavity is packed with NPLs devoid of any spacer, allowing a larger population of emitters to couple to the cavity. The NPL-filled cavity system shows a Rabi splitting of 74.5 meV compared to the previously obtained 41.5 meV Rabi splitting with an NPL-in-PMMA cavity at room temperature. Angle-resolved reflectance and photoluminescence measurements are performed to explore the polariton photophysics by varying the cavity-exciton detuning and temperature. The role of dark states as a reservoir in redistributing polariton populations is also investigated. Mixed quantum-classical dynamics calculations are performed to model the polariton system wherein the theoretical simulations agree with the experimental observations, providing a fundamental understanding of the polariton dynamics within the NPL-cavity hybrid system. These room-temperature exciton-polaritons have the potential to unlock new chemical reaction pathways as well as pave the way for developing cutting-edge quantum technologies.

Authors: Wang Qianqian , Miao Zhiwei , Xiao Xiongjie , Zhang Xu , Yang Daiwen , Jiang Bin , Liu Maili
Published: October 2023

The fast motions of proteins at the picosecond to nanosecond timescale, known as fast dynamics, are closely related to protein conformational entropy and rearrangement, which in turn affect catalysis, ligand binding and protein allosteric effects. The most used NMR approach to study fast protein dynamics is the model free method, which uses order parameter S2 to describe the amplitude of the internal motion of local group. However, to obtain order parameter through NMR experiments is quite complex and lengthy. In this paper, we present a machine learning approach for predicting order parameters based on protein NMR structure ensemble. A random forest model is used to learn the relationship between order parameters and structural features. Our method achieves high accuracy in predicting order parameters for a test dataset of 10 proteins, with a Pearson correlation coefficient of 0.817 and a root-mean-square error of 0.131.
A Quantum Definition of Molecular Structure
Authors: Lang Lucas , Cezar Henrique Musseli , Adamowicz Ludwik , Pedersen Thomas Bondo
Published: October 2023

Molecular structure, a key concept of chemistry, has remained elusive from the perspective of all-particle quantum mechanics despite many efforts. Viewing molecular structure as a manifestation of strong statistical correlation between nuclear positions, we propose a practical method based on Markov chain Monte Carlo sampling and unsupervised machine learning. Application to the D3+ molecule unambiguously shows that it possesses an equilateral triangular structure. These results provide a major step forward in our understanding of molecular structure from fundamental quantum principles.
Enolate addition to bicyclobutanes enables expedient access to 2-oxo-bicyclohexane scaffolds
Authors: Woelk Kyla , Dhake Kushal , Schley Nathan , Leitch David
Published: October 2023

We report the synthesis of 2-oxo-bicyclo[2.1.1]hexanes (2-oxo-BCHs) from bicyclobutanes (BCBs) and readily available enolate precursors. We propose this reaction proceeds via initial enolate addition to the bicyclobutane, followed by an intramolecular acyl substitution by the resulting enolate intermediate. Glycine-derived enolates directly give protected 2-oxo-3-amino-BCH derivatives that can be further functionalized. Arylacetate derivatives are also suitable enolate precursors, giving 2-oxo-3-aryl-BCH scaffolds from readily available starting materials.

Humanising Pedagogy in Mathematics Education at South African Technical and Vocational Education and Training (TVET) Colleges: Influence on TVET Teaching and Learning
Authors: Vimbelo Siphokazi , Bayaga Anass
Published: October 2023

This study examines the implementation of a humanising pedagogy in teaching mathematics at a TVET college in South Africa. Despite the country's transition to democracy, disempowerment and dehumanisation persist within the education system, particularly affecting learners from previously disadvantaged backgrounds. Mostly, TVET mathematics classrooms are neither humanised as mathematics is taught in isolation with social issues nor linked to students’ lived experiences. Student engagement is minimal as the classroom environment is a banking zone model. The study explores how a humanising pedagogy, based on critical pedagogy principles, can address these challenges. A humanised pedagogy has been explored through workshops and lesson presentations that were based on humanising pedagogy. Findings reveal that the adoption of a humanising pedagogy enhanced student engagement as the teaching strategies were engaging and student centred. Students were actively involved; mathematics was linked to students’ lived experiences. Additionally, the adoption of a humanising pedagogy helped students and teachers to see the relationship between the content and real life and how they can use mathematics to address social problems. The study highlights the need to humanise mathematics teaching and calls for educators to become agents of social change. Embracing a humanising pedagogy can foster a more inclusive, responsive, and equitable education system.

Authors:   The Korea Association Of Governance Studies, Han Myungseong , Lah T. J.
Published: October 2023

This study aimed to identify the causes of the phenomenon of silence among public officials using the Conservation of Resource Theory. The study categorized types of silence into acquiescent, defensive, prosocial and adaptive silence as dependent variables and set up citizenship pressure, ‘Nun-chi’, job stress, and job engagement as independent variables. The results analyzed through a survey of 400 south korean public officials showed that citizenship pressure had a positive relationship with acquiescent, prosocial, and adaptive silence. Job stress had a positive relationship with acquiescent and defensive silence, while job engagement had a negative relationship with aquiescent and defensive silence, and nun-chi showed a positive relationship with defensive and adaptive silence. In particular, the interaction between citizenship pressure, job stress, and job engagement revealed that job stress amplified the escalation of acquiescent and defensive silence prompted by citizenship pressure, while job engagement mitigated it. This study holds theoretical implications in clarifying the dynamics of silence occurrence within public organizations.

Physicochemical and Microstructural Characterization of Klias Peat, Lumadan POFA, and GGBFS for Geopolymer Based Soil Stabilization
Authors: Amaludin Adriana E. , Asrah Hidayati , Mohamad Habib M. , Bin Amaludin Hassanel Z. , Bin Amaludin Nazrein A.
Published: October 2023

Peat soils are highly heterogeneous and considered problematic because they have a high moisture content and low shear strength. It requires stabilization to enhance its engineering properties before it is transformed into a viable construction material. The use of geopolymers as stabilizer materials for weak soils has been on the rise recently due to their low carbon footprint compared to the use of conventional stabilizer materials like cement. Geopolymerization occurs as a result of the alkali activation of aluminosilicate materials. In this study, peat soil and the aluminosilicate materials Palm Oil Fuel Ash (POFA) and Ground Granulated Blast Furnace Slag (GGBFS) are characterized to assess their suitability as geopolymer precursor materials. A series of laboratory studies were carried out to determine the physicochemical properties of the materials, such as particle size distribution, moisture and organic content, specific gravity, pH, and electrical conductivity. Furthermore, the XRD, XRF, and FESEM tests were carried out to ascertain the mineral characteristics, elemental chemical composition, and morphological characteristics of these materials, respectively. The peat soil is classified as hemic peat with sufficient aluminosilicate content (Si/Al ratio of 2.11). The POFA is identified as Class F pozzolan with adequate Si+Al+Fe oxide content (67.9%), as stipulated by ASTM C618. The GGBFS material was found to be appropriate for geopolymer production, with a Si/Al ratio of 2.17, a hydration modulus of 2.38 (good hydration), and a basicity coefficient of 1.32 (alkaline material favorable for geopolymerization). Based on the geopolymer precursor material suitability assessment criteria, all the materials assessed were deemed suitable for geopolymerization, and the effectiveness of POFA-GGBFS geopolymer to improve peat soil properties should be studied in depth. At present, there are limited studies pertaining to the use of alkali-activated POFA-GGBFS blends to improve peat soil properties. As a result of this material characterization phase, planned works involving the compressive strength testing program on alkali-activated POFA-GGBFS-peat soil blends at ambient temperature will be carried out in the near future. The eventual aim of this research is to remediate the peat soil to be repurposed as road subgrade material. Doi: 10.28991/HIJ-2023-04-02-07 Full Text: PDF
The impact of ESG factors on Russia’s banking sector
Authors: Yuzvovich Larisa I. , Maramygin Maksim S. , Lvova Mayya I.
Published: October 2023

An important condition for the successful incorporation of ESG principles in banks’ activity is reflecting the data on the implementation of environmental, social and governance activities in the reporting for stakeholders. The paper aims to build the models of ESG factors’ impact on the banking industry. Methodologically, the study rests on the theories of ESG banking and green (responsible) finance and uses the methods of dialectical and economic statistical analysis. By means of correlation analysis the authors reveal causal relationships and establish the ESG factors affecting the banking sector of the Russian Federation. The obtained data point to the importance of green finance within the framework of the sustainable environmental and economic development of the banking industry. The study does not fully confirm the thesis that following the ESG principles will lead to an increase in the profitability and efficiency of the banking sector: only social factors directly influence the performance of the banking sector, while environmental factors have an inverse effect, and there is no relationship with the governance factors. The findings can be useful while incorporating ESG principles in the regulation of financial markets and in investment practices. This will enable the organisations in the banking sector to form an ESG-based strategy, control the factors affecting the financial sustainability of the baking industry, manage ESG risks based on an extensive dialogue with stakeholders, and win goodwill.

The study undertaken in 13 varieties of safflower indicated that highest genotypic and phenotypic coefficient of variation was observed in number of seeds on primary branches followed by yield per plant. The lowest was for days to maturity. Herita- bility values ranged from 43.48 per cent for number of primary branches and 98.62 per cent for number of seeds on primary branches. These traits also combined with high genetic advance. indicating scope for the improvement of these characters through selection. Highly significant und positive correlation existed between yield per plant with number of seeds on primary branches and secondary branches and with number of primary branches.

Results of a five year field trial in a permanent layout showed that no more then 100 per cent replenishment of nitrogen removed by weeds was necessary to reduce weed competition. Increasing rates of simazino significantly increased maize yield but since it tended to decrease wheat yields, half a kilogram of simazine as pre-emergence rear- ment was the best treatment vis-a-vis treedom from harmful residual effect of higher rates on wheat. Pre+post-emergence application providing 0.5 kg 2,4-D/ha along with replenishment of 100 per cent N removed by weeds was the most beneficial treatment. Increase in maize yield and reduction in weed dry matter production with the use of simazine at half a kg/ha rate were 4.2 and 13.2 g/ha. respectively without harmful effect on wheat.

The present study was aimed at finding out the validity of a number of soil tests for K. using different extractants by relating them to uptake. The experiments were conducted in red and black soils of Coimbatore, under field conditions. creating -varying levels of soil potassium in mini-plots under natural agro-climatic conditions so as to be valid for field trials. Two crops, onion and maize were chosen as test crops to study the plant factors. Nine different methods besides the Neubauer test were used for assessing the availability. None of the soil test methods. tried in the present study. was universally suitable for all the crops and soils. Neubauer test was found to be not useful in black soil for both the crops although in red soil it was useful in the case of maize. From the study. it therefore appears that unless certain norms are evolved to include plant and soil characteristics the estimation and adoption of available K index to predict K avallability and uptake have very little practical value.

Quinalphos (Ekalux EC 25) was diluted to 4.4% ( 1.1% a. i.) and sprayed norially on cotton fields affected with pests. Simultaneously, for toxicological evaluation of the product, cattle. goats and birds were placed in the field during spraying and directly exposed to the spray. The plasma cholinesterase enzyme estimation and haematological studies were conducted in these animals and birds at pre-exposure, 24 hours and 48 hours post-exposure time. Quinalphos did not produce any toxic symptoms or any toxicity indicative deviations in the plasma cholinesterase levels or haematological parameters.

A study was conducted to understand the effect of different seed-sizes on quanti. tative characters like plant-height, girth of stem. number of leaves, days to flower. days to maturity, diameter of head, yield per plant. yield/ha, shelling percentage and 100 seed weight. Significant differences were observed for all the ten characters studied. The largest seeds had more plant height. stem girth, number of leaves. head diameter. shelling percentage 100 seed-weight, yield per plant and yield per hectare. The plants grown from largest seeds flowered and matured earlier. The present study revealed that graded and bold seeds should be used for obtaining maximum yield.

The effect of concentration and source of added nitrogen (N*H_{1}) and N*O_{2} ) on nodulation, nitrogen fixation. yield and content of N. P. K. Ca and Mg of soybean (Glycine max (L.) Merr.cv.Amsoy) were studied in nutrient solution medium. Nodulation and nitrogen fixation were severely suppressed by the addition of nitrogen source either N*H_{1} or mathbb NO 3 , The degree of suppression was more pronounced in the presence of N*O_{3} than NH, and the reduction of nodulation and nitrogen fixation was more intensified at later stages of soybean growth. Addition of N*H_{1} decreased the dry weight of roots whereas fN*O_{2} increased it and the production of tops followed the same pattern for the two forms of nitrogen studied. By the increase of NH, concentration in nutrient solution. N and P contents were found to increase in the roots and shoots while there was a reduction in the content of aleph 1 Ca and N*t_{0} Unlike aleph H_{mu} N*O_{3} increased the uptake of cations as well.

The study was undertaken with the object of investigating the seasonal variations in the denitrifying bacterial population and the pattern of distribution in the various horizons of red and black soils. Observations were recorded for twelve months. The data showed that there is difference in the population in red and black soils. The cyclic variation of the denitrifiers was found to be a function of the rainfail distribution over the area. The population is most concentrated in the first 30 cm of the soil profiles and decreased with increase in depth till 90 cm. Thereafter, the population did not show variation with depth.
