The Effect of Financial Architecture, Cash Holding, and Goodwill on Stock Return with the Approach Five-Factor Models

This study examines the effect of financial architecture, cash holding and goodwill on stock returns using a 5-factor model approach. The financial architecture variables consist of corporate governance (Board of Commissioners, Board of Directors, and board process), capital structure, and ownership structures (managerial and institutional holdings). Testing was conducted using Weighted Least Square Method (WLS) in 25 companies from 2015-2018 selected in purposive sampling at the group of Compass 100 Index in Indonesia Stock Exchange. The calculation of the stock return in this study uses an abnormal return and as a comparison is also a test using models with expected return and actual return. The results of this study show the Board Process and the capital structure have a significant effect on stock return in the regression model with abnormal return. The results on the model with expected return show that managerial ownership has a significant effect and the model with actual return shows that only cash holding has a significant effect. In addition, the variables of the Board of Commissioners, the Board of Directors and institutional ownership in the comparison model show results that consistently do not have a significant effect on stock returns.
INQUIRIES INTO EPISTEMOLOGIES AND ETHICS – COLLABORATIVE KNOWLEDGE PRODUCTION IN CROSS-GENERATIONAL RESEARCH

Collaborative research is not a new concept in cultural anthropology. Still, it has become increasingly relevant, and this new relevance may be most visible in the foundation of the journal Collaborative Anthropologies (University of Nebraska Press) in 2008. Today, collaboration is seen, in a broad sense, as referring to the whole research process including the collaborative development of research design and theory building.2 This has not always been the case. Starting from the writing-culture-debate at the latest,3 social and cultural anthropology has established an understanding of people in the studied field as research partners rather than as a researched population and has developed a large variety of forms of relationships and research strategies for practicing this collaborative attitude. The discussion and epistemological reflection of how researchers collaborate in their varying field approaches has become an integral part of most ethnographic studies, and is often aligned to research-ethical questions as another unavoidable dimension of anthropological knowledge production.4
Learning Lower Bounds for Graph Exploration With Reinforcement Learning

We explore the usage of reinforcement learning for theoretical computer science. Reinforcement learning has shown to ﬁnd solutions in challenging domains such as Chess or Go. Theoretical problems, such as ﬁnding the worst possible input for an algorithm come with even more vast, combinatorial search spaces. In this paper, we look at the example of online graph exploration. Here we want to ﬁnd graphs that yield a high competitive ratio for a greedy explorer. The search space consists of having every edge being either present or absent. Given there are quadratically many possible edges in a graph and each subset of edges is a possible solution, this yields unfeasibly large search spaces even for few nodes. We show experimentally how clever constraints can keep such search spaces manageable. As a result, we can learn graphs that resemble those known from literature and even improve them to yield higher competitive ratios.
Preparation, Structure and Giant Magnetoresistance of Electrodeposited Fe-Co/Cu Multilayers

No systematic studies have been carried out on the giant magnetoresistance (GMR) of electrodeposited (ED) Fe-Co/Cu multilayers since the elaboration of a method for the optimization of the Cu layer deposition potential. In this paper, we present results on the electrochemical optimization of the Cu layer deposition potential which was found to depend on the relative iron concentration in the bath. An X-ray diffraction study of ED Fe5Co95(1.5 nm)/Cu(dCu) multilayers with dCu ranging from 0.8 nm to 10 nm revealed an fcc structure. For most of the multilayers, weak superlattice satellite reflections could be identified. The room-temperature magnetoresistance was studied in detail as a function of the individual layer thicknesses. Multilayers with Cu layer thicknesses above about 1.5 nm were found to exhibit a GMR behavior with a maximum GMR of about 5 % and a typical saturation field of 1 kOe. The GMR magnitude decreased with increasing Fe-content in the magnetic layer. The spacer layer thickness evolution of the MR data was established in detail after separating the ferromagnetic and superparamagnetic GMR contributions and no oscillatory GMR was found. A comparison with literature data on both physically deposited and ED Fe-Co/Cu multilayers is also made.
Supplementation of Freezing Media with Cyclic Adenosine Monophosphate Analog and Isobutylmethylxanthine on Sperm Quality

Background: This study aimed to explore whether the addition of a cyclic adenosine monophosphate (cAMP) analog and isobutylmethylxanthine (IBMX) in freezing media improved sperm quality and what role cAMP has in this recovery. Materials and methods: ach semen sample was cryopreserved into four groups: fresh semen sample, as a control group, freezing medium + 2.5 mM cAMP analog and 0.2 mM IBMX, freezing medium + 12.5 mM cAMP analog and 0.2 mM IBMX, and freezing medium + 25 mM cAMP analog and 0.2 mM IBMX. Sperm parameters after post-thaw were analyzed according to WHO instruction (2010). Viability, acrosome reaction, and DNA damage levels of the samples were evaluated. Results: Our results indicated that the effective concentrations of 12.5 and 25 mM cAMP analog and 0.2 mM IBMX significantly improved the total motility, progressive motility, and viability of the frozen-thawed (P<0.05). However, non-progressive motility and immotile were significantly reduced in the 12.5 and 25 mM cAMP analogs and 0.2 mM IBMX groups after thawing (P<0.05). During freezing the spermatozoa, the high concentration of the cAMP analog increased acrosome reaction after thawing in the 25 mM and 0.2 mM IBMX treated samples (P<0.05). DNA fragmentation in 25 mM cAMP analog and 0.2 mM (IBMX) supplementation was significantly lower compared to the other groups (P<0.05). Conclusions: Our findings revealed that in vitro cAMP analog and IBMX supplementation in freezing media play an important role in preventing cryodamage by maintaining the sperm functional parameters.
Schinus molle Leaves Compost Improves the Growth, Quality and Productivity of Strawberry ( Fragaria × Ananassa Duch) in Potting Culture

: Schinus molle leaves, compost (SLC) incorporated with soil at different volume rates contrasted with control (soil alone), intending to improve and stimulating strawberry growth. Anecdotal accounts of SLC for these purposes the experiment has examined the impacts of SLC on strawberry growth and production responses. This research assessed the impacts of a six volume% (v: v) rates of SLC combined with soil at 0, 20, 40, 60, 80 and 100 of growing medium (field soil). The pots RCBD experiment included four replicates designed at the faculty of agriculture, Sana’a University. Plants cultivated in 20% SLC was significantly ( p< 0.05) greater than control (field soil) in leaf area, yield, fruit weight and crown DM% by about 12.8% 25.8%, 20.4% and 101.6% subsequently. Meanwhile, transplants grown in 80 and 100% SLC developed the highest quantity of crowns and longer of peduncle. Transplants grown in 60% SLC was the poorest of flower number per plant measured with other treatments. Plants in 100% SLC showed the significantly downer of a DM% in the roots and crown parts 65.3% and 82.7% lower than control, respectively, nevertheless, composed the significantly greater 50.4% of fruit TSS than the control treatment. The variation between the SLC rates on the root characters showed that the 100% SLC increased the roots network volume cm 3 , root length cm2 root surface area cm 2 , specific root length cm. This study illustrates the benefit of that application SLC.

Differences in Kinematic Characteristics Between 2-point and 3-point Basketball Shooting Motions – A Case Study

Basketball has become one of the most popular international sports in which a successful game outcome is highly contingent upon optimal shooting performance. The purpose of this case study was to quantify and examine the kinematic changes in shooting motion as a player progresses from mid-range 2-point shots to beyond the 3-point line. One former collegiate basketball player performed 50 mid-range 2-point (5.20m) and 50 3-point (6.75m) shots divided into 10 sets separated by 1-2-minute rest intervals. Two high-definition cameras recording at 30 fps positioned perpendicular to the subject’s sagittal plane of motion were used for data collection. The first camera positioned 10 m away was used to capture body kinematics, while the second camera positioned 15 m away was used to capture the trajectory data. The kinematic variables captured at the initial phase of the shooting motion (Phase1) were knee angle, hip angle, ankle angle, elbow height, shoulder angle, elbow angle, and basketball height and at the time point of ball release (Phase 2) were shoulder angle at release, heel height, basketball release height, trajectory height, and ball entry angle. The findings of this case study indicate that greater flexion in the knee joint during the Phase 1 and greater heel height indicating larger vertical displacement during the Phase 2 of the shooting motion were the main kinematic adjustments influenced by the increased shooting distance. Therefore, we may assume that these changes were made to achieve greater ground reaction forces to compensate for the increased distance from the rim.
The Health Costs of Cost-Sharing

We use the design of Medicare’s prescription drug benefit program to demonstrate three facts about the health consequences of cost-sharing. First, we show that an as-if-random increase of 33.6% in out-of-pocket price (11.0 percentage points (p.p.) change in coinsurance, or $10.40 per drug) causes a 22.6% drop in total drug consumption ($61.20), and a 32.7% increase in monthly mortality (0.048 p.p.). Second, we trace this mortality effect to cutbacks in life-saving medicines like statins and antihypertensives, for which clinical trials show large mortality benefits. We find no indication that these reductions in demand affect only ‘low-value’ drugs; on the contrary, those at the highest risk of heart attack and stroke, who would benefit the most from statins and antihypertensives, cut back more on these drugs than lower risk patients. Similar patterns exist for other drug–disease pairs, and irrespective of socioeconomic circumstance. Finally, we document that when faced with complex, high-dimensional choice problems, patients respond in simple, perverse ways. Specifically, price increases cause 18.0% more patients (2.8 p.p.) to fill no drugs, regardless of how many drugs they had been on previously, or their health risks. This decision mechanically results in larger absolute reductions in utilization for those on many drugs. We conclude that cost-sharing schemes should be evaluated based on their overall impact on welfare, which can be very different from the price elasticity of demand.
Industry Diversity, Competition and Firm-Relatedness: The Impact on Employment Before and After the 2008 Crisis Forthcoming in: Regional Studies

This study investigates the extent to which indicators of external scale economies impacted employment growth in Canada over the period 2004-2011. We focus on knowledge spillovers between firms while accounting for Marshallian specialization, Jacobs’ diversity, and competition by industry, as well as related and unrelated firm varieties in terms of employment and sales. We find that the employment growth effects of local competition and diversity are positive, while the effect of Marshallian specialization is negative. Diversification is found to be particularly important for employment growth during the Global Financial Crisis and immediately thereafter.
Sugar and free amino acid composition of five cultivars of dates from offshoots or vitroplants in open fields

Cette etude compare la composition en sucres et en acides amines, a maturite, de dattes de palmier obtenus par differentes methodes de multiplication. Les resultats des analyses morphologiques et chimiques effectuees sur les cultivars Bou Sthammi noire, Mejhool, Thoory et Zahidi ne montrent pas de differences significatives entre les cultivars obtenus par une multiplication vegetative traditionnelle ou par la methode de multiplication in vitro realisee par l'equipe francaise de recherche sur le palmier dattier. Ces resultats pourraient indiquer que les vitroplans sont conformes a l'arbre mere. Des cinq cultivars etudies, seule la variete Deglet Nour, obtenue a partir de cals (embryogenese somatique) montre des differences dans la composition en sucre et acides amines. Les vitroplans de Deglet Nour contiennent davantage d'acide glutamique, d'acide -amino-butyric et d'arginine mais moins d'alanine. Ce qui laisse supposer que ces variations ont ete introduites par micromultiplication
Basal-like breast cancer with low TGFβ and high TNFα pathway activity is rich in activated memory CD4 T cells and has a good prognosis

Basal-like breast cancer (BLBC) is a type of high-grade invasive breast cancer with high risk of recurrence, metastases, and poor survival. Immune activation in BLBC is a key factor that influences both cancer progression and therapeutic response, although its molecular mechanisms are not well clarified. In this study, we examined five cancer immunity-related pathways (IFNα, IFNγ, STAT3, TGFβ and TNFα) in four large independent breast cancer cohorts (n = 6,381) and their associations with the prognosis of breast cancer subtypes. Activities of the 5 pathways were calculated based on corresponding pathway signatures and associations between pathways and clinical outcomes were examined by survival analysis. Among the five PAM50-based subtypes, BLBC had the highest IFNα, IFNγ, TNFα pathway activities, and the lowest TGFβ activity. The IFNα, IFNγ, TNFα pathway activities were negatively correlated with BLBC recurrence. In contrast, positive association and no association with BLBC recurrence were observed for TGFβ and STAT3 pathways, respectively. TNFα/TGFβ pathway combination improved the prediction of recurrence and chemotherapy response of BLBCs. Immune cell subset analysis in BLBC showed that M0, M1 and M2 macrophage levels were associated with either TNFα or TGFβ pathways, whereas the level of activated memory CD4 T cells were associated with both pathways. Moreover, this T cell subset was most abundant in BLBCs with low TGFβ and high TNFα pathway activities. These results suggested that cooperation of TNFα and TGFβ signaling may be involved in the regulation of memory T cells and anti-cancer immunity in BLBCs. Our data also demonstrate that TNFα/TGFβ pathway combination may represent a better biomarker for BLBC prognosis and clinical management.

A Regional Semi-Distributed Streamflow Model Using Deep Learning

Abstract: Recent studies have shown that deep learning models in hydrological applications significantly improved streamflow predictions at multiple stations compared to traditional machine learning approaches. However, most studies lack generalization; i.e. researchers are training separate models for each location. The spatial and temporal generalization ability of deep learning models in hydrology that can be gained by training a single model for multiple stations is evaluated in this study. We developed a generalized model with a multi-site structure for hourly streamflow hindcasts on 125 USGS gauges. Considering watershed-scale features including drainage area, time of concentration, slope, and soil types, the proposed models have acceptable performance and slightly higher median NSE value than training individual models for each USGS station. Furthermore, we showed that the trained generalized model can be applied to any new gauge in the state of Iowa that was not used in the training set with acceptable accuracy. This study demonstrates the potential of deep learning studies in hydrology where more domain knowledge and physical features can support further generalization.
Title Psychological detachment: A creativity perspective on the link between intrinsic motivation and employee engagement

Purpose – The purpose of this paper is to develop an additional perspective on when and why intrinsic motivation predicts employee engagement by presenting a contextual boundary of psychological detachment regarding the relationship between intrinsic motivation, employee creativity, and employee engagement. Design/methodology/approach – Data were collected from 288 full-time Japanese workers using an online survey. We used a bootstrap method (Preacher & Hayes, 2008) to test mediation and a Hayes method (2013) to test moderation and a first-stage moderated mediation model. Findings – Employee creativity mediated the relationship between intrinsic motivation and employee engagement, and the relationship between intrinsic motivation and creativity was moderated by psychological detachment. Additionally, the indirect effect of intrinsic motivation on employee engagement via creativity was moderated by psychological detachment. Research limitations/implications – The cross-sectional design may have limited the empirical inferences; however, the proposed model was based on robust theoretical contentions, and the study included an unrelated “marker variable” (Neuroticism) as an effective means of identifying common method variance (CMV), thus mitigating the limitation of the design. Practical implication – This study has shown that intrinsically motivated employees who practice psychological detachment from work achieve higher creativity and stronger employee engagement. Originality/value – Based on the unconscious thought theory (UTT), job demand resource theory (JD-R), recovery processes (i.e., effort-recovery model), and self-determination theory (SDT), this paper adds to the literature by demonstrating the mediating and moderating mechanisms driving intrinsic motivation and employee engagement relationships.

Physicochemical Properties of Calcium Lignosulfonate with Different Molecular Weights as Dispersant in Aqueous Suspension

Five purified calcium lignosulfonate (CL) fractions with different molecular weights were obtained by fractionation using ultrafiltration and dialysis. The influence of molecular weight on their physicochemical properties was investigated by determining the properties of five fractions. TEM and ESEM imaging indicated that CL has a globular structure to form locally regular colloidal assemblies with the diameter of approximately 200 ∼ 300 nm. Fraction3 (M w is 7621) with the molecular weight of 5,000–l0,000 has more sulfonic and carboxyl group, so the highest zeta potential (−36 mV) can be charged on the TiO2 particles. With the increase of molecular weight, the hydrophobicity and surface activity of CL in aqueous solution increase, so Fraction5 (M w is 21646) which molecular weight is more than 30000 has the biggest adsorption amount. The adsorption characteristic of CL on solid-water interface have great impact on the dispersive properties of TiO2 particle in aqueous solution and the higher adsorption capacity is helpful to improve the dispersive ability of CL. On the other hand, the surface charge of TiO2 particle absorbing CL is another important factor to the dispersive ability of CL. Furthermore, when the CL concentration in TiO2 suspension is less than 4 mg/mL, Fraction3 has the best dispersive ability because the electrostatic repulsion effect is controlling factor. The dispersive ability of CL increases with the increase of molecular weight when the CL concentration in TiO2 suspension is more than 4 mg/mL, so Fraction5 has the best dispersive ability owing to the steric hindrance effect.
A survey of the fungal contamination and presence of ochratoxin A and zearalenone on Spanish feed and raw materials

The incidence of fungal contamination in 91 samples of feed and raw materials used for animal feeding in Spain has been studied. Sample analysis was accomplished in a new culture medium to which a beta-cyclodextrin had been added, and a comparison with other more usual culture media was performed. Ochratoxin A (OTA) and zearalenone (ZEA) contamination of all the samples was evaluated by RP-HPLC with fluorescence detection. The fungal genera found, such as Penicillium and Fusarium, included mycotoxigenic strains as OTA and ZEA (33.3 and 26.4% incidence respectively). One sample of corn and another of cotton seed were contaminated with levels of OTA above the 5 and/or 10 µg kg−1 recommended by the legislation of several European countries, whereas none of the samples contaminated with ZEA surpassed the legislation limits suggested by the official agencies.

The Future of Labor: Automation and the Labor Share in the Second Machine Age

We study the effect of modern automation on firm-level labor shares using a 2018 survey of 1,618 manufacturing firms in China. We exploit geographic and industry variation built into the design of subsidies for automation paid under a vast government industrialization program, “Made In China 2025,” to construct an instrument for automation investment. We use a canonical CES framework of automation and develop a novel methodology to structurally estimate the elasticity of substitution between labor and automation capital among automating firms, which for our preferred specification is 3.8. We calibrate the model and show that the general equilibrium implications of this elasticity are consistent with the aggregate trends during our sample period.
On the Interaction between Monetary and Macroprudential Policies

The Global Financial Crisis fostered the design and adoption of macroprudential policies throughout the world. This raises important questions for monetary policy. What, if any, is the relationship between monetary and macroprudential policies? In particular, how does the effectiveness of macroprudential policies (or lack thereof) influence the conduct of monetary policy? This discussion paper builds on the insights of recent theoretical and empirical research to address these questions.
