Using Transactions Data to Improve Consumer Returns Forecasting

Although generous return policies have been shown to have marketing benefits, such as a higher willingness to pay and a higher purchase frequency, counterbalancing these benefits is an increased volume of consumer returns, which presents significant operational challenges for both retailers and original equipment manufacturers (OEMs). Since accurate return forecasts are inputs into strategic and tactical decision support tools for operations managers, advancements in forecast accuracy can yield better-managed returns. The forecasting approach developed in this paper incorporates transaction-level data, such as purchase and return timestamps, and predicts future return quantities using a two-step “predict–aggregate” process. To enhance the generalizability of our framework, we test it on two distinct datasets provided by a bricks-and-mortar electronics retailer and an online jewelry retailer. We find that our approach demonstrates significant forecasting error reduction, in the range of 10% to 20%, over benchmark models constructed from common industry practice and existing literature. As our approach leverages the same data inputs as existing models, it can be easily adapted by practitioners. We also consider a number of extensions to generalize our approach into contexts such as restricted return time window, new product returns, and inflated same-day returns. Last, we discuss broad implications of return forecast accuracy improvements in the areas such as inventory management, staffing level, reverse logistics, and return recovery decisions.
Theoretical Research of Single Ferrite Tuner Systems with Magnetic Field Modulation in the Ion Cyclotron Range of Frequency

Abstract Ion cyclotron resonance heating is a reliable tool for high-power and long-pulse operation in fusion reactors. However, a sudden increase in the reflected radio-frequency (RF) power poses serious problems such as L- to H-mode transition or edge-localized modes that must be solved for future fusion reactors. It is necessary to place an impedance matching system between the RF generator and antenna to mitigate the adverse effects of the variations. The idea of a fast-response ferrite stub tuner was developed to trace the load variation of the antenna. This study presents theoretical calculation of the suitable normalized mechanical length of the ferrite stub tuner using transmission line theory and numerically analyzes the impedance matching parameters of the single ferrite stub antenna system. The present study demonstrates the feasible investigation of the magnetic field modulation, which can lead to the effective reduction in the reflected RF power fraction during the large change in plasma resistance.
IMPACT OF CAROTID ENDARTERECTOMY ON COGNITIVE PERFORMANCE AND DEPRESSIVE SYMPTOMS

OBJECTIVES: This study aims to evaluate the impact of carotid endarterectomy (CEA) on cognitive performance in patients with severe carotid disease and depressive symptoms, and to explore the possible associations between certain demographics, clinical characteristics, and cognitive function and depression. MATERIALS AND METHODS: The study included 48 patients, who were referred for endarterectomy. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) scale, while depressive symptoms were assessed using the patient health questionnaire(PHQ-9) scale. An assessment of cognitive and depressive symptoms was performed 1–3 days before surgery, and then six months after. RESULTS: A paired sample t-test found that the difference in the mean MoCA score between the before (=23.37; SD ± 3.27) and the after (=24.69; SD ± 3.68) surgery results was 1.32 (95% CI = 0.48 – 2.16; p = 0.003; Cohen’s d value = 0.95). A paired sample t-test showed that a decrease in mean PHQ-9 score of > 10 for patients six months after CEA (7.5±4.6) was statistically significant ( p = 0.019; Cohen’s d value = 1.32) compared with the PHQ-9 scores at baseline (12.6 ± 2.8). CONCLUSION: Carotid artery endarterectomy seems to have beneficial effects on the course of cognitive impairment and depressive symptoms in patients with severe carotid artery stenosis. Demographic, clinical characteristics (age, gender, comorbidities, previous stroke) did not have impact on course of cognitive and depressive symptoms. A limitation in our study was that the number of patients was relatively small, therefore we intend to perform further study with larger case volume to estimate the impact of carotid artery endarterectomy on cognitive functions and depressive symptoms.
The impact of birth-related injury and pain on breastfeeding outcomes

Reasons for premature discontinuation of breastfeeding are complex; a variety of social, psychological and physical factors may contribute to a deviation from a mother's breastfeeding plan. The aim of this research was to investigate how actual experiences of birth and breastfeeding differed from the mother's pre-birth intentions, and any subsequent perceived impact on breastfeeding experience. Data were collected via an online survey of UK-based women (n=1000). Respondents faced a variety of challenges when breastfeeding, including nipple soreness and pain, concerns around milk insufficiency, and birth-related pain which impacted their ability to breastfeed comfortably. Predominantly, birth-related pain made breastfeeding difficult rather than preventing it, however 5% of mothers surveyed cited it as contributing to premature cessation of breastfeeding. Pain relating to birth may be an under-considered factor in early cessation of breastfeeding. Considering the challenges experienced when establishing and maintaining breastfeeding, it is essential to consider the cumulative pain and discomfort experienced from all sources.
Credit default swaps and CEO compensation: a long-term perspective

ABSTRACT In this paper, we examine whether the onset of credit default swaps (CDSs) affects a firm’s executive compensation. The availability of CDSs allows lenders to transfer credit risk, but not control or monitoring rights, to CDS sellers. Hence, CDS-protected lenders’ incentives to monitor borrowing firms are curtailed, which could exacerbate the managerial agency problem. To mitigate the concern about the increased agency problem, we postulate that shareholders are more likely to demand greater long-term compensation for CEOs to compensate for their reduced ability to delegate monitoring to CDS-protected lenders. Consistent with our hypothesis, we find a positive CDS-incentive horizon relationship. Moreover, the positive relationship is more pronounced for institutional investors who have stronger incentives for monitoring. This study contributes to the literature by examining the impact of CDSs on executive compensation design, which has been largely overlooked in prior research.
Influence of Stocking Density with Different Light System on the
 Growth Performance and Behavior in Broiler Chickens

This study evaluated the effects of stocking density on performance and behavioral activities of 35-day-old broilers in relation to incandescent white bulb (IB) light and LED yellow and white light. A total of 1,650 day-old chicks were weighed and randomly allocated into six treatment groups in a 2 × 3 factorial arrangement based on stocking density (14 birds m and 22 birds m) and color of lights (IB; monochromatic LED yellow and white light) with five replicates for each treatment. The results showed that final body weight, weight gain and feed conversion of broilers were improved at a stocking density of 14 birds m with exposure to LED lights. Similarly, broilers spent more time exhibiting inactive behavior (e.g. standing) and active behaviors (e.g. walking and walking plus pecking) under 14 birds m with exposure to lights as compared that of other treatment groups. Regarding a stocking density of 22 birds m, broilers performance traits were negatively affected and also activities were less. The performance of broilers was not significantly altered for the main factor of different lights but broilers were less inactive (e.g less time spent sitting plus standing) and more time spent active behavior in walking under IB light than LED light. Thus, we concluded that a stocking density 14 birds m with exposure to LED light significantly improved broiler performance and behavioral activity and these conditions could therefore improve the overall welfare of farmed chickens.

Endosidin20 is a broad-spectrum cellulose synthesis inhibitor with an herbicidal function

Cellulose is an important component of plant cell wall that controls anisotropic cell growth. Disruption of cellulose biosynthesis often leads to inhibited cell growth. Endosidin20 (ES20) was recently identified as a cellulose biosynthesis inhibitor (CBI) that targets the catalytic domain of Arabidopsis cellulose synthase 6 (CESA6) to inhibit plant growth. Here, we characterized the effects of ES20 on the growth of some other plant species and found that ES20 is a broad-spectrum plant growth inhibitor. We compared the inhibitory effects of ES20 and other CBIs on the growth of cesa6 plants that have reduced sensitivity to ES20. We found that most of the cesa6 with reduced sensitivity to ES20 show normal inhibited growth by other CBIs. ES20 also shows synergistic inhibitory effect on plant growth when applied together with other CBIs. We show ES20 has a different mode of action than tested CBIs isoxaben, indaziflam and C17. ES20 not only inhibits Arabidopsis growth under tissue culture condition, it inhibits plant growth under soil condition after direct spraying. We demonstrate that plants carrying two missense mutations can tolerate dual inhibition by ES20 and isoxaben. One sentence summary Cellulose biosynthesis inhibitor Endosidin20 has synergistic effect with other cellulose synthesis inhibitors and has the potential to be used as a spray herbicide.
Innovation, Competition, and Incentives: Evidence from Uruguayan Firms

Using a sample of manufacturing firms in Uruguay, this paper studies the eect of product market competition on innovative activities, labor practices and the provision of incentives within firms. Our estimates show that a higher level of product market competition: (i) decreases innovative expenditures, (ii) increases the number of innovations per dollar spent on innovative activities, and: (iii) leads firms to implement incentive payment schemes based on employee performance. These results suggest that, in developing economies, firms react to a higher level of product market competition by providing internal incentives that ultimately lead to significant increases in the productivity of their innovative outlays.
Carotid Plaques and Multiple Brain Infarctions

Cerebral ischemic lesions sometimes are clinically characterized by major cognitive impairment such as vascular dementia. Among the quantifiable factors able to cause focal and/or diffuse ischemic lesions, carotid atherothrombotic plaques represent possible "foci" of embolism that lead to cortical and/or subcortical infarcts. The aim of the present study was to investigate the qualitative and quantitative aspects of carotid plaques in a group of patients affected by vascular dementia and a group of patients affected by multiple brain infarctions, in order to verify whether significant differences can be detected. These data point out the importance of plaque composition and morphology in the pathogenesis of brain infarction leading to dementia.
Portable Automated Rapid Testing (PART) for auditory assessment: Validation in a young adult normal-hearing population

This study aims to determine the degree to which Portable Automated Rapid Testing (PART), a freely-available program running on a tablet computer, is capable of reproducing standard laboratory results. Undergraduate students were assigned to one of three within-subject conditions that examined repeatability of performance on a battery of psychoacoustical tests of temporal fine structure processing, spectro-temporal amplitude modulation, and targets in competition. The Repeatability condition examined test/retest with the same system, the Headphones condition examined the effects of varying headphones (passive and active noise-attenuating), and the Noise condition examined repeatability in the presence of recorded cafeteria noise. In general, performance on the test battery showed high repeatability, even across manipulated conditions, and was similar to that reported in the literature. These data serve as validation that suprathreshold psychoacoustical tests can be made accessible to run on consumer-grade hardware and performed in less controlled settings. This dataset also provides a distribution of thresholds that can be used as a normative baseline against which auditory dysfunction can be identified in future work.
Sensitivity and specificity of clinical criteria in the detection of histologic atypia in nevi

A retrospective, double-blinded clinicopathological study was performed in a series of acquired melanocytic nevi (n = 128) to assess the level of concordance between clinical and histopathological features and to analyze the sensitivity and the specificity of clinical parameters in the detection of histological atypia. The overall concordance between clinical and histological aspects was poor (Cohen's K statistics = 0.21; 95% CI = 0.13-0.30): in the group of clinically common nevi, the 50% of them were histologically common melanocytic nevi (CMN), 41% were nevi with architectural disorder (NAD) and 9% were nevi with architectural disorder plus cytologic atypia (NADCA)
Mechanisms of Regulation of Cytoplasmic Dynein

Cytoplasmic dynein-1 (dynein) is a microtubule-based motor protein that is essential for maintaining proper spatial and temporal organization of the cellular interior during both interphase and cell division. To do so, dynein carries out diverse functions including transport of intracellular cargos, organelle anchoring, mitotic spindle assembly and nuclear migration. To carry out these diverse functions, dynein is regulated by multiple factors including Lis1, dynactin and activating adaptors. In this thesis, I present interdisciplinary work investigating the mechanisms of regulation of dynein. In chapter 2, a combination of biochemistry, single-molecule assays and cryo-electron microscopy was used to investigate how yeast dynein is regulated by Lis1. Previous work showed that Lis1 binds directly to dynein’s AAA+ motor domain and slows its motility by causing dynein to tightly bind microtubules. The work presented here revealed that in addition to this role, Lis1 can also induce dynein to weakly bind microtubules. The mode of regulation used by Lis1 is determined by the nucleotide state at dynein’s third AAA domain and the stoichiometry of the Lis1-dynein interaction. Both modes of Lis1 regulation of dynein are required for dynein to position the mitotic spindle in yeast cells. In chapter 3, the mechanism of regulation of human dynein by Lis1 is investigated. Human dynein requires dynactin and an activating adaptor for directional long-distance movement on microtubules. The work presented here shows that Lis1
Impact of organic fertilisation on lettuce biomass production according to the cultivation duration in tropical soils

ABSTRACT The productivity levels of two arenosol (Ar40) and fluvisol (FL40) fields that had been cultivated for over 40 years were compared to that of fields with the same soils located nearby but never previously cultivated, i.e. Ar0 and FL0, respectively. Application of poultry manure (PM) and sewage sludge (SS) were compared to a mineral fertilizer (T100), corresponding to 100 kg/ha of nitrogen, over three lettuce (Lactuca sativa L.) crop cycles. PM and SS were applied at 50 and 150 kg/ha nitrogen equivalent fertilizer doses. Biomass production levels in the organic and mineral treatments were similar, except for the SS-50 for FL0 and the PM-150 for Ar40, FL40 and FL0. Biomass production levels of Ar40 were higher than those of Ar0 for the first cycle. In the initial state, the soil P content in Ar40 was higher than that of the Ar0 soil. With the treatment repetition, Ar0 showed the same production level as Ar40. For the fluvisols, biomass production levels of FL40 were lower than those of FL0 for the first cycle. Indeed, the initial nitrate content in FL40 was lower than in FL0. The biomass production levels of FL40 were higher than those of FL0 for the following cycles.
Pre-operative hypoalbuminemia is a major risk factor for anastomotic leak in emergency gastrointestinal resection and anastomosis

Background: The serum albumin level is one of several clinical parameters of the status of general health. Hypoalbuminemia is known to be associated with delayed wound healing. The hypoalbuminemic state interferes with the normal functioning of the gastrointestinal tract. This study evaluates the relation of pre-operative albumin level and the risk for anastomotic leak in emergency gastrointestinal resection and anastomosis. Methods: A total of 112cases that meet the inclusion and exclusion criteria are included from Bangalore Medical College and Research Institute, Karnataka, India for a duration of 18 months November 2014 to October 2016.51 cases belonged to the stapled group and 61 cases belonged to the sutured group. Anastomosis using the two techniques, stapled and hand sewn anastomosis are evaluated separately. Results: The relation of pre-operative serum albumin and anastomotic leak is analysed in each study group separately and found that a pre-operative albumin of <3.5gm/dl is significantly associated with post-operative anastomotic leak, with a p-value of 0.0418 (p<0.05) in stapled anastomosis group and a p-value of 0.0357 (p<0.05) in hand sewn anastomosis group. Conclusions: Pre-operative albumin of <3.5gm/dl is significantly associated with post-operative anastomotic leak in both the groups, irrespective of the technique adopted.
CUSTOMERS’ DEPOSIT BEHAVIOUR IN DUAL BANKING INDUSTRY: A MARKET STRUCTURE ANALYSIS

Background and Purpose: The aim of this paper is to evaluate public acceptance toward Islamic banking system in Malaysia by using the market structure analysis as proposed in industrial organizational studies. The structural approach framework was used to evaluate the nature and changes of market concentration in the Malaysian Islamic and conventional deposit markets. Methodology: The well-known market concentration measure, namely concentration ratio (CR) is calculated to study the changes in saving behaviour among depositors in both banking markets. The concentration ratios of deposits for both banking markets are evaluated by using the banking firms’ level data for the period 1997–2016. Pearson and Spearman correlation analysis was also used to investigate the relationship between the total deposits and bank-specific variables. Findings: It is found that interest or profit rate paid to the depositors are the factor that greatly affect the depositors’ choice of banks to save their money. Besides, experience doing businesses is more important to Islamic banks compared to conventional banks in order to attract depositors. Contributions: The findings demonstrate that societies, especially the Islamic community, are still loyal to conventional banks, which have more experience in the banking operation. The findings of this study are expected to open the eyes of the Muslim community to use Islamic banking services, which are certainly sharia-compliance.

Interannual Variability of the Natal Pulse

Satellite altimetry data and high‐resolution model output are used to investigate the mechanism of interannual variations of the solitary meander in the Agulhas Current, called the Natal Pulse. It is shown that most of the Natal Pulses are triggered by anticyclonic eddies originating from the Southeast Madagascar Current (SEMC) and anticyclonic eddies of the Mozambique Channel are the secondary source. In addition to the barotropic conversion suggested by previous studies, the advection of eddy kinetic energy (EKE) plays a statistically significant role in the growth of the Natal Pulse. The number of anticyclonic eddies arriving at the Natal Bight largely explains the interannual variations in the Natal Pulse. The barotropic conversion from the SEMC, whose interannual variations are likely related to the remote wind forcing, is the main EKE source and corresponds well with the interannual variations of anticyclonic eddies generated off the southern coast of Madagascar. It is also shown that the interannual variations of the Natal Pulse are linked to large‐scale wind variability in the southern Indian Ocean. Plain Language Summary Natal Pulse is the large meander of the Agulhas Current originating in the Natal Bight and it affects both the local marine environment and global ocean circulation. Previous observational studies suggested that the occurrence of the Natal Pulse varies from year‐to‐year. Since oceanic eddies tend to trigger the Natal Pulse, we investigate the relationship between the Natal Pulse and incoming eddies in this study. We show that variations of the Natal Pulse are mainly explained by variations of eddies propagating from the south of Madagascar and the Mozambique Channel. We also show that variations in the Natal Pulse are linked to the large‐scale wind variability over the southern Indian Ocean. This study is the first to show the mechanism of the year‐to‐year variations in the Natal Pulse.
