The Dual Challenge of Search and Coordination for Organizational Adaptation: How Structures of Influence Matter

Organizations increasingly need to adapt to challenges in which search and coordination cannot be decoupled. In response, many have experimented with “agile” and “flat” designs that dismantle traditional forms of hierarchy to harness the distributed knowledge of specialized individuals. Despite the popularity of such practices, there is considerable variation in their implementation as well as conceptual ambiguity about the underlying premise. Does effective rapid experimentation necessarily imply the repudiation of hierarchical structures of influence? We use computational models of multiagent reinforcement learning to study the effectiveness of coordinated search in groups that vary in how they influence each other’s beliefs. We compare the behavior of flat and hierarchical teams with a baseline structure without any influence on beliefs (a “crowd”) when all three are placed in the same task environments. We find that influence on beliefs—whether it is hierarchical or not—makes it less likely that agents stabilize prematurely around their own experiences. However, flat teams can engage in excessive exploration, finding it difficult to converge on good alternatives, whereas hierarchical influence on beliefs reduces simultaneous uncoordinated exploration, introducing a degree of rapid exploitation. As a result, teams that need to achieve agility (i.e., rapid satisfactory results) in environments that require coordinated search may benefit from a hierarchical structure of influence—even when the apex actor has no superior knowledge, foresight, or capacity to control subordinates’ actions.
Fetal Outcomes in Preterm Cesarean Sections

Introduction Neonatal mortality is a major challenge in low-middle-income countries. The current study was conducted to assess the association between preterm cesarean delivery and fetal outcomes. Methods A prospective study was conducted at the Combined Military Hospital in Peshawar, Pakistan, from October 1, 2020, to March 31, 2021. All women reporting to the hospital with a cephalic presentation and singleton pregnancies between the 27th and 34th weeks of gestation were included in the study. Pregnancies with an abnormal presentation, those diagnosed with a congenital abnormality, and those with indications for growth restriction or preterm delivery were excluded from the study. We also excluded infants delivered via vacuum or forceps. The outcomes of interest in this study included neonatal death prior to discharge, neonatal respiratory distress, sepsis, intraventricular hemorrhage (IVH), seizure, subdural hemorrhage (SDH), or appearance, pulse, grimace, activity, and respiration (APGAR) test score of less than 7 at five minutes. Maternal features including diabetes, hypertension and gestational age of delivery, parity, previous cesarean sections (CS), and last pregnancy outcomes were documented in a predefined pro forma. Results Our sample size consisted of 288 women, who were classified into two groups. Group A comprised 144 women who gave birth vaginally and group B consisted of 144 women who underwent CS. It was observed that women who underwent cesareans had a higher likelihood of a history of hypertension and related pathologies. It was also observed that these women had a greater likelihood of being of higher age compared to women who underwent vaginal deliveries. Neonates of women who had CS were at a greater risk of presenting with respiratory distress than those who had spontaneous vaginal deliveries. Conclusion Based on our findings, respiratory distress was significantly more common in babies of women who delivered via CS. However, there was no difference in neonatal outcomes in terms of IVH, seizures, SDH, and APGAR score of <7.
Nanoporous Carbon Electrodes Derived from Coffee Side Streams for Supercapacitors in Aqueous Electrolytes

Coffee, as one of the most traded resources, generates a vast amount of biogenic by-products. Coffee silver skins (CSS), a side stream from the roasting process, account for about 4 wt. %. Despite the abundancy of CSS, possible routes to generate added value for broad applications are limited. Herein, we present an approach to use CSS as a precursor material for supercapacitor electrodes. KOH activated carbon (AC) was produced from CSS. The resulting AC—CSS was characterized by X-ray diffraction, gas sorption analysis, scanning electron microscopy, and Raman spectroscopy. The highly porous AC—CSS exposes a specific surface area of more than 2500 m2 g−1. Electrodes formed with AC—CSS were electrochemically characterized by performing cyclic voltammetry and galvanostatic cycling. The electrodes were further assembled into a supercapacitor device and operated using 1 M sulfuric acid as electrolyte. In addition, various quinones were added to the electrolyte and their impact on the capacitance of AC—CSS electrodes was analyzed. In this work, we were able to show that CSS are a valuable source for supercapacitor applications and that coffee-waste-derived quinones can act as capacitance enhancers. Thus, the findings of this research show a valuable path towards sustainable and green energy storage solutions.
Evaluation of a workplace alcohol prevention program targeted on managers’ inclination to initiate early alcohol intervention

BACKGROUND: Alcohol interventions targeting the adult population are often conducted in healthcare settings, while preventive interventions often target adolescents or young adults. The general working population is often overlooked. A workplace-based intervention, consisting of development and implementation of an organizational alcohol policy, and skills development training for managers (APMaT) was carried out in order to prevent and reduce alcohol-related harms by identifying hazardous consumers at an early stage. OBJECTIVE: This study aims to evaluate APMaT by focusing on managers’ inclination to initiate early alcohol intervention. METHODS: In a cluster randomized design, data were obtained from 187 managers (control: n = 70; intervention: n = 117). Inclination to initiate early alcohol intervention was measured using three items on a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). Changes in managers’ inclination to intervene were analyzed by applying multilevel ordered logistic regression. Predictors included in the model were group (control vs. intervention), time (baseline vs. 12-month follow-up), and the multiplicative interaction term (group×time). RESULTS: Significant increase in inclination to intervene against hazardous alcohol consumption among managers in the intervention group compared to managers in the control group was observed. Specifically, a 50% increase of confidence to initiate an intervention was observed among managers in the intervention group. CONCLUSIONS: APMaT seems effective to increase managers’ inclination to intervene early against hazardous consumption in the workplace. The effectiveness of APMaT at the employee level should be explored in prospective studies.
IN SILICO, TO DETERMINE THE ACTIVE COMPOUNDS OF BLACK TEA AND TURMERIC IN INCREASING THE ACTIVITY OF THE ENZYME SOD

Damage to cells caused by stress can be reduced by the presence of antioxidants, one of which is Superoxide dismutase (SOD). The role of the active ingredients of black tea and turmeric will be studied using the in-silico method to identify the active compounds as components in SOD activation. The bioavailability and toxicity of the active compounds of black tea and turmeric were studied and followed by molecular docking and virtual games. The parameters studied are Gibbs's free energy (∆G) and binding site similarity (BSS). The results were analyzed using Gibbs's free energy (∆G) and binding site similarity (BSS) parameters. It was found that those that could increase the activity of Cu/Zn SOD enzymes were Epicatechin gallate (black tea) and curcumin (turmeric), with values ​​of -9.5 and -7.4 Kcal/mol and the same BSS value of 81.8%. The control ligand used was beta amyrin. According to Lipinski's rules, Epicatechin gallate and curcumin compounds can be absorbed well and are safe for consumption. This study concludes that Epicatechin gallate, an active compound of black tea, and curcumin, an active compound of turmeric rhizome, have the best potential to increase the activity of Cu/Zn SOD enzymes based on the results of virtual screening and molecular docking. Epicatechin gallate and curcumin are predicted to be well absorbed by the body because they qualify Lipinski's rules and are not toxic and safe for consumption.
DIURNAL CIRCADIAN VARIATION IN PHOTOSYNTHESIS IN Dracaena sanderiana UNDER CONTRASTING TEMPERATURE AND LIGHT

Dracaena sanderiana is prominent and in-demand cut foliage in the global ornamental industry. This study was conducted to examine the stress responses of Dracaena sanderiana under contrasting temperature and light conditions by using chlorophyll fluorescence (ChlF) transient analysis technique. D. sanderiana cuttings were held in distilled water and subjected to two different light levels, i.e., 22,500±2,000 lux and 750±200 lux allowing two distinct temperature levels. The chlorophyll fluorescence data were collected through OJIP analysis using a portable fluorometer (FluorPen, FP 110). The measurements were recorded four times a day (9 am, 12 pm, 3 pm, and 6 pm) and the data were collected continuously for four days commencing from the first day of treatment application. The major parameters derived from the OJIP analysis, including specific energy fluxes per reaction center (ABS/RC, TR/RC, ET/RC, and DI/RC), flux ratios (maximum quantum yield of primary photochemistry-φPo, electron transport efficiency -ψo, and quantum yield of electron transport –φEo and maximum quantum yield of non-photochemical de-excitation- φDo), and performance index (PI) were recorded. ChlF data showed a clear unimodal diurnal variation in plant performances of D. sanderiana at 22,500±2,000 lux. The circadian variation was reported for all measured ChlF parameters except the ψo, TR/RC, and ET/RC. Based on these circadian variations of ChlF, it can be concluded that D. sanderiana displays a facultative CAM pathway as an adaptation to the stressed conditions.
Associations between genetic risk for trait aggression and alcohol use predicting alcohol-related aggression

A propensity for aggression and/or alcohol use may be associated with alcoholrelated aggression. Previous research has shown genetic overlap between alcohol use and aggression, but has not looked at how alcohol-related aggression may be uniquely influenced by genetic risk for aggression and/or alcohol use. The current study examined the associations of genetic risk for trait aggression, antisocial behavior, and alcohol use with alcohol-related aggression using a polygenic risk score (PRS) approach. Using genome-wide association study (GWAS) summary statistics, PRSs were created for trait aggression, antisocial behavior, alcohol consumption, and alcohol dependence. These four PRSs were used to predict alcohol-related aggression in two independent samples, the University of California at San Francisco (UCSF) Family Alcoholism Study (n=1164) and the National Longitudinal Study of Adolescent to Adult Health (Add Health; n=4291). Results indicated significant associations of PRSs for trait aggression, antisocial behavior, and alcohol consumption predicting alcohol-related aggression in the UCSF study sample with the most significant results pertaining to verbal aggression. PRSs for alcohol consumption were also associated with hitting a family member, and PRSs for alcohol dependence were associated with hitting anyone else in the UCSF study sample. No significant associations were observed in the Add Health study sample. Together, these results provide preliminary evidence that genetic influence for alcohol use and aggression uniquely predict different aspects of alcohol-related aggression.
Are Fund Investors Treated Fairly? An Investigation of Taiwan Fund Company Strategies

This paper aims to explore whether a corporate-level strategy exists among fund companies that drives them to maximize the company’s interest at the expense of fiduciary duties to stakeholders. The results show a significant difference between high-value and low-value fund returns within the same fund company. In addition, this difference is significantly bigger in domestic fund companies than in foreign-capital fund companies, especially in high-tech funds. Our study suggests that a fund company’s self-discipline, internal control and audit regulation, as well as on-site examination of governmental au-thority and functional enhancement of custodian banks become increasingly important in the asset management industry.
Science and Hurling: A Review

Hurling is one of the world’s fastest field sports. Since the last review of science and Gaelic sports in 2008, there has been an increase in sports science provisions across elite and sub-elite cohorts, resulting in increased hurling-specific literature equating to an additional 111 research investigations into the game across all sports science disciplines. The present review aims to provide an updated analysis of the current research on the game and propose recommendations for future research. Overall, intermittent aerobic fitness remains an important physical quality during competition, with a focus on games-based training methodologies within the literature. Within the current review, we provide updated normative data on the running demands, physiological responses, and anthropometric and performance profiles of hurling players. The increased literature across the sport has led to the development of a hurling-specific simulation, that can now be utilised practically in training and research processes for hurling cohorts. Furthermore, the monitoring of internal and external training loads across training and match environments, in addition to response variables such as well-being, appears to have become more prominent, allowing practitioners to design training regimes to achieve optimal dose and response characteristics. Analysing the game from a scientific perspective can allow for more efficient preparatory practices, to meet the specific requirements of players at all age levels. Collaborative research among the various sports science disciplines, is required to identify strategies to reduce the incidence of injury and enhance performance in hurling. The current review provides updated information to coaches and practitioners regarding position-specific physical qualities, and match-play demands that can concurrently support the training process within hurling.
Stir Casting Process Analysis and Optimization for Better Properties in Al-MWCNT-GR-Based Hybrid Composites

Pure aluminium poses inferior properties that limit its use in load-bearing applications. Reinforcing multiwall carbon nano-tube (solid lubricant) and graphene to aluminium matrix offers better (antifriction, hardness, and wear resistance) properties in composites for such applications. A stir casting processing route is employed to prepare the hybrid composite (aluminium-multiwall carbon nanotube-graphene Al-MWCNT-GR). The Taguchi L16 experimental matrix representing four variables (percent reinforcement of graphene, die temperature, melt temperature, and stir speed) operating at four levels were studied to analyze and obtain higher hardness and low wear rate in hybrid composites. Percent reinforcement of graphene showed maximum impact, and die temperature resulted with the least contribution towards both the responses. Criteria importance through intercriteria correlation (CRITIC) method is applied to determine the weight fractions (importance) for hardness and wear rate equal to 0.4752 and 0.5482, respectively. Grey relational analysis (GRA) and multi-objective optimization by the ratio analysis (MOORA) method converts multiple objective functions into a single objective function with weight fractions assigned to each output. Taguchi-CRITIC-MOORA outperformed the Taguchi-CRITIC-GRA method, which could result in 31.77% increase in hardness and a 36.33% decrease in wear rate compared to initial conditions. The optimal conditions ensure a dense microstructure with minimal pores, result in enhanced properties compared to that obtained for initial and average stir casting conditions. The worn-out surface results in a few thin and slender grooves between tracks with less crack propagation, ensuring self-lubrication in composites fabricated with the optimized condition. The better properties resulted in the hybrid composites correspond to optimized stir casting conditions and can be implemented in industries for large-scale applications.
Bunyaviral N Proteins Localize at RNA Processing Bodies and Stress Granules: The Enigma of Cytoplasmic Sources of Capped RNA for Cap Snatching

Most cytoplasmic-replicating negative-strand RNA viruses (NSVs) initiate genome transcription by cap snatching. The source of host mRNAs from which the cytoplasmic NSVs snatch capped-RNA leader sequences has remained elusive. Earlier reports have pointed towards cytoplasmic-RNA processing bodies (P body, PB), although several questions have remained unsolved. Here, the nucleocapsid (N) protein of plant- and animal-infecting members of the order Bunyavirales, in casu Tomato spotted wilt virus (TSWV), Rice stripe virus (RSV), Sin nombre virus (SNV), Crimean-Congo hemorrhagic fever virus (CCHFV) and Schmallenberg virus (SBV) have been expressed and localized in cells of their respective plant and animal hosts. All N proteins localized to PBs as well as stress granules (SGs), but extensively to docking stages of PB and SG. TSWV and RSV N proteins also co-localized with Ran GTPase-activating protein 2 (RanGAP2), a nucleo-cytoplasmic shuttling factor, in the perinuclear region, and partly in the nucleus when co-expressed with its WPP domain containing a nuclear-localization signal. Upon silencing of PB and SG components individually or concomitantly, replication levels of a TSWV minireplicon, as measured by the expression of a GFP reporter gene, ranged from a 30% reduction to a four-fold increase. Upon the silencing of RanGAP homologs in planta, replication of the TSWV minireplicon was reduced by 75%. During in vivo cap-donor competition experiments, TSWV used transcripts destined to PB and SG, but also functional transcripts engaged in translation. Altogether, the results implicate a more complex situation in which, besides PB, additional cytoplasmic sources are used during transcription/cap snatching of cytoplasmic-replicating and segmented NSVs.
Serum Zinc Level in Patients with Severe Genital Warts: A Case-Control Study in a Dermatology Hospital

Background Genital warts are a common sexually transmitted disease (STD), and there is no method that completely prevents its recurrence. Recently, zinc has been used in the treatment of cutaneous warts. Nondestructive action, ease of use, and promising results with low chances of relapse were reflected in the treatment. These effects may arise from the immunomodulatory activity of zinc in the event of a viral infection. Objectives This study was aimed at identifying the relationship between the serum zinc level and the clinical characteristics of patients with genital warts. Materials and Methods A case-control study was conducted. Genital warts were diagnosed by clinical examination, and disease severity was demonstrated based on the number of affected sites or the spread of lesions. The serum zinc level was measured using atomic absorption spectrophotometry. Results A total of 78 patients with genital warts and 78 healthy volunteers were enrolled in the study. The mean serum zinc level in the genital wart group was lower than that in the control group (81.83 ± 13.99 μg/dL vs. 86.66 ± 17.58 μg/dL); however, this difference was not statistically significant (P > 0.05). The mean concentrations of serum zinc in patients having more than one affected site, spread > 2 cm2, or ten or more lesions were significantly lower than those of the control group (P < 0.05). Conclusions The results suggested that severe genital warts may be associated with a low serum zinc level in patients.
Numerical methods for the extended Fisher-Kolmogorov (EFK) equation

In the study of pattern formation in bi-stable systems, the extended Fisher-Kolmogorov (EFK) equation plays an important role. In this paper, some a priori bounds are proved using Lyapunov functional. Further, existence, uniqueness and regularity results for the weak solutions are derived. Using C1-conforming finite element method, optimal error estimates are established for the semidiscrete case. Finally, fully discrete schemes like backward Euler, two step backward difference and Crank-Nicolson methods are proposed, related optimal error estimates are derived and some computational experiments are discussed.
Metrically universal abelian groups

We give a positive answer to the question of Shkarin (\emph{On universal abelian topological groups}, Mat. Sb. 190 (1999), no. 7, 127-144) whether there exists a metrically universal abelian separable group equipped with invariant metric. Our construction also gives an example of a group structure on the Urysohn universal space that is substantially different from the previously known examples. Under some cardinal arithmetic assumptions, our results generalize to higher cardinalities.
Comparison of modeling approaches for evaluation of machine fleets in central Sweden forest operations

ABSTRACT There are many factors to consider when deciding which technologies to use in forest operations and how to plan their use. One important factor is the overall cost when choosing between the established two-machine system (TMS) with a harvester and a forwarder, and a one-machine system with a harwarder in final fellings. Such considerations can be done with different model approaches, all of which have their strengths and weaknesses. The aim of this study was to analyze and compare the TMS and harwarder potential using a Detailed Optimization (DO) approach and an Aggregated Heuristic (AH) approach. The main differences are the aggregation of seasons, including machine system teams, and spatial considerations. The analyses were done for one full year of final fellings for a large forest company’s region in central Sweden, containing information necessary for calculating costs for logging, relocation between stands and traveling between the operator’s home bases and the stands. The approaches were tested for two scenarios; when only TMS were available, and when both TMS and harwarders were available. The main results were that the approaches coincided well in both potential to decrease total costs when harwarders where available, and distribution of TMS and harwarders. There were some differences in the results, which can be explained by differences in thecalculation approach. It was concluded that the DO approach is more suitable when detailed analyses are prioritized, and the AH approach is more suitable when a more approximate analysis will suffice or the available resources for making the analysis are more limited.
Logical systems I: Lambda calculi through discreteness

This paper shows how internal models for polymorphic lambda calculi arise in any 2-category with a notion of discreteness. We generalise to a 2-categorical setting the famous theorem of Peter Freyd saying that there are no sufficiently (co)complete non-degenerate categories. As a simple corollary, we obtain a variant of Freyd theorem for categories internal to any tensored category. Also, with help of introduced concept of an associated category, we prove a representation theorem relating our internal models with well-studied fibrational models for polymorphism.
