Evaluating Count Prioritization Procedures for Improving Inventory Accuracy in Retail Stores
Authors: DeHoratius Nicole , Holzapfel Andreas , Kuhn Heinrich , Mersereau Adam J. , Sternbeck Michael 
Published: September 2022

Problem definition: We compare several approaches for generating a prioritized list of items to be counted in a retail store, with the objective of detecting inventory record inaccuracy and unknown out of stocks. Academic/practical relevance: We consider both “rule-based” approaches, which sort items based on heuristic indices, and “model-based” approaches, which maintain probability distributions for the true inventory levels updated based on sales and replenishment observations. Methodology: Our study evaluates these approaches on multiple metrics using data from inventory audits we conducted at European home and personal care retailer dm-drogerie markt. Results: Our results support arguments for both rule-based and model-based approaches. We find that model-based approaches provide versatile visibility into inventory states and are useful for a broad range of objectives but that rule-based approaches are also effective as long as they are matched to the retailer’s goal. We find that “high-activity” rule-based policies, which favor items with high sales volumes, inventory levels, and past errors, are more effective at detecting inventory discrepancies. The best policies uncover over twice the discrepancies detected by random selection. A “low-activity” rule-based policy based on low recorded inventory levels, on the other hand, is more effective at detecting unknown out of stocks. The best policy detects over eight times the unknown out of stocks found by random selection. Managerial implications: Our findings provide immediate guidance to our retail partner on appropriate methods for detecting inventory record inaccuracy and unknown out of stocks. Our approach can be replicated at other retailers interested in customized optimization of their counting programs.

Smoothed Variable Sample-Size Accelerated Proximal Methods for Nonsmooth Stochastic Convex Programs
Authors: Jalilzadeh Afrooz , Shanbhag Uday , Blanchet Jose , Glynn Peter W. 
Published: September 2022

We consider the unconstrained minimization of the function F, where F = f + g, f is an expectation-valued nonsmooth convex or strongly convex function, and g is a closed, convex, and proper function. (I) Strongly convex f. When f is μ-strongly convex in x, traditional stochastic subgradient schemes ( SSG ) often display poor behavior, arising in part from noisy subgradients and diminishing steplengths. Instead, we apply a variable sample-size accelerated proximal scheme (VS-APM) on F, the Moreau envelope of F; we term such a scheme as ( mVS-APM ) and in contrast with ( SSG ) schemes, ( mVS-APM ) utilizes constant steplengths and increasingly exact gradients. We consider two settings. (a) Bounded domains. In this setting, ( mVS-APM ) displays linear convergence in inexact gradient steps, each of which requires utilizing an inner ( prox-SSG ) scheme. Specically, ( mVS-APM ) achieves an optimal oracle complexity in prox-SSG steps of [Formula: see text] with an iteration complexity of [Formula: see text] in inexact (outer) gradients of F to achieve an ϵ-accurate solution in mean-squared error, computed via an increasing number of inner (stochastic) subgradient steps; (b) Unbounded domains. In this regime, under an assumption of state-dependent bounds on subgradients, an unaccelerated variant ( mVS-APM ) is linearly convergent where increasingly exact gradients ∇xF(x) are approximated with increasing accuracy via ( SSG ) schemes. Notably, ( mVS-APM ) also displays an optimal oracle complexity of [Formula: see text]; (II) Convex f. When f is merely convex but smoothable, by suitable choices of the smoothing, steplength, and batch-size sequences, smoothed (VS-APM) (or sVS-APM) achieves an optimal oracle complexity of [Formula: see text] to obtain an ϵ-optimal solution. Our results can be specialized to two important cases: (a) Smooth f. Since smoothing is no longer required, we observe that (VS-APM) admits the optimal rate and oracle complexity, matching prior ndings; (b) Deterministic nonsmooth f. In the nonsmooth deterministic regime, (sVS-APM) reduces to a smoothed accelerated proximal method (s-APM) that is both asymptotically convergent and optimal in that it displays a complexity of [Formula: see text], matching the bound provided by Nesterov in 2005 for producing ϵ-optimal solutions. Finally, (sVS-APM) and (VS-APM) produce sequences that converge almost surely to a solution of the original problem.

Published: September 2022

ResumoEstamos passando por um período de intensa precarização da mão de obra trabalhadora, sentida e externalizada, inclusive, por meio da arte. Dentre essas expressões artísticas, elegemos a música “O drama da humana manada”, da banda El Efecto, para analisarmos o atual cenário do trabalho no Brasil. Estabelecendo um diálogo entre a música escolhida, a noção de trabalho alienado de Marx e o Direito do Trabalho, percebemos que o processo de alienação do trabalhador tem se tornado ainda mais perceptível com o avanço da agenda neoliberal.Palavras–Chave: Classe trabalhadora; Alienação do trabalhador; Direitos trabalhistas. Abstract We are going through a period of intense precariousness in the labor force, felt including through art. Among these artistic expressions, we chose the song “O drama da humana manada”, by the band El Efecto, to analyze the current scenario of work in Brazil. Establishing a dialogue between the chosen music, Marx's notion of alienated work and Labor Law, we realize that the process of alienating the worker has become even more noticeable with the advancement of the neoliberal agenda.Key words: Working class; Alienation of the worker; Labor rights.

Authors: Ariyarajah Archchun , Berry Isha , Haldane Victoria , Loutet Miranda , Salamanca-Buentello Fabio , Upshur Ross E. G. 
Published: September 2022

Background
The rapid implementation of global COVID-19 vaccination programs has surfaced many challenges and inequities, particularly in low- and middle-income countries (LMICs). However, there continues to be a lack of consensus on which challenges are global priorities for action, and how to best respond to them. This study uses consensus-based methods to identify and rank the most important challenges and solutions for implementation of COVID-19 vaccination programs in LMICs.

Methods
We conducted a three-round modified Delphi study with a global panel of vaccine delivery experts. In Round I, panelists identified broad topical challenges and solutions. Responses were collated and coded into distinct items. Through two further rounds of structured, iterative surveys panelists reviewed and ranked the identified items. Responses were analyzed qualitatively and quantitatively to achieve consensus on the most important COVID-19 vaccine delivery challenges and solutions.

Results
Of the 426 invited panelists, 96 completed Round I, 56 completed Round II, and 39 completed Round III. Across all three rounds there was equal representation by gender, and panelists reported work experience in all World Bank regions and across a variety of content areas and organizations. Of the 64 initially identified items, the panel achieved consensus on three challenges and 10 solutions. Challenges fell under themes of structural factors and infrastructure and human and material resources, while solutions also included items within themes of communication, community engagement, and access and planning, processes, and operations.

Conclusion
COVID-19 vaccine delivery is challenged by long-standing and structural inequities that disadvantage health service delivery in LMICs. These findings can, and should, be used by global health organizations to efficiently and optimally direct resources to respond to these key challenges and solutions.

Published: September 2022

Pela inexistência de informações sobre as propriedades mecânicas de sementes de abóbora e pela necessidade de desenvolver equipamentos que possam ser utilizados com mais eficiência para o seu processamento, objetivou-se com este projeto, estudar as propriedades mecânicas de sementes de abóboras comerciais cultivadas no IF Goiano. Foram utilizadas sementes de abóbora (Cucurbita moschata) das cultivares comercial ‘Rajada Seca Melhorada’ e ‘Jacarezinho’ com teor de água variando de 0,670 a 0,094 decimal base seca (b.s.) e 0,923 a 0,033 decimal (b.s.), respectivamente. A determinação da resistência à compressão das sementes foi realizada por meio de ensaios de compressão uniaxial. As sementes foram comprimidas em sua posição natural de repouso, a uma velocidade constante (taxa de aplicação de força) de 0,0001 m s-1. A força média para as deformações na ‘Rajada Seca Melhorada’ foi de 43,90 e 0,56 N e para ‘Jacarezinho’ entre 13,20 e 0,20 N, e os valores do módulo proporcional de deformidade de 8,05 a 23,68 x 107 N m-2 cultivar ‘Rajada Seca Melhorada’ e 2,05 a 21,64 x 107 N m-2 para ‘Jacarezinho’. Conclui-se que a força necessária para deformação das sementes de abóbora decresce com o aumento do teor de água, para a cultivar ‘Rajada Seca Melhorada’ e ‘Jacarezinho’. Há um aumento nos valores do módulo proporcional de deformidade com a redução do teor de água, para a cultivar ‘Rajada’ e ‘Jacarezinho’. Pode-se observar que as sementes da abóbora ‘Rajada Seca Melhorada’ possuem uma maior resistência à força de deformação em relação a “Jacarezinho’.
Endothelial dysfunction of the mesenteric arteries of rats in the early obesity induced by high-fat diet
Authors: Pankova M. N. 
Published: September 2022

Background: Disturbance of the morphological and functional properties of the vascular bed in obesity are a serious clinical problem. Basis to their development is endothelial dysfunction. The developed models of obesity in animals using various diets indicate a change in vascular reactivity, however, questions about the stage at which this occurs and what mechanisms are involved in this process remain open, while they are decisive for choosing the correct tactics for correcting dysfunctions.Aim: The aim of the present study is to determine the changes in acetylcholine (ACh)-induced vasodilation of isolated arteries from rats after six weeks of administration of a high-fat diet (HFD).Materials and methods: The experiments were performed on Sprague-Dawley males, which at the age of 8 weeks were divided into 2 experimental groups that were treated for the next 6 weeks in the following manner: 1 - control) with standard dry food; 2 - a group fed with a HFD, the total amount of fat in which was 50%. At finish of the diet, the degree of obesity, biochemical parameters in the blood, and blood pressure were measured. Intravital microscopy of the rat mesentery with video recording was used to study the reactivity of the vessels. The contractile and relaxant responses of the vessels were determined by changes in their diameter.Results: The rats after treatment with the HFD (n=15) had higher body weight and amount of visceral fat, significantly increased blood triglycerides, moderate increases in glucose level in blood and systolic pressure compared with the control (n=15). Relaxation responses of mesenteric arteries, having a diameter of 140 to 300 μm in PSS, were recorded after precontraction by phenylephrine. A decrease in ACh-induced vasorelaxation was obtained, which manifests itself before the development of significant changes in carbohydrate metabolism. Incubation of drugs with the inhibitor of endothelial NO synthase L-NAME led to a pronounced weakening of relaxation in animals on a standard diet, and had little effect on vasodilation in the arteries of rats with the HFD. Vasodilation induced by the administration of sodium nitroprusside (NO donor) did not differ significantly in control and experimental animals, which indicates that the sensitivity of vascular smooth muscle to NO remained practically unchanged. ACh-induced relaxation of arteries in dietary rats did not change when the cyclooxygenase pathway was blocked by diclofenac.Conclusion: Functional changes in the contractile activity of the mesenteric arteries, manifested in the form of a decrease in ACh-induced vasorelaxation, occur after treatment with the HFD when animals had an early stage of obesity development before the onset of pronounced disorders of carbohydrate metabolism. This decrease is mainly due to the disruption of the NO-dependent mechanism underlying ACh-induced relaxation in the norm.

Waduk Kedung Ombo adalah waduk yang terletak di perbatasan tiga kabupaten yaitu Kabupaten Grobongan, Kabupaten Boyolali, dan Kabupaten Sragen tepatnya di Kecamatan Geyer, Kabupaten Grobogan, Jawa tengah. Waduk Kedung Ombo mempunyai peran penting sebagai sumber perairan untuk berbagai keperluan. Namun seiring berjalannya waktu, Waduk Kedung Ombo mengalami penurunan kualitas dikarenakan permasalahan kondisi waduk serta permasalahan kawasan di sekitarnya. Permasalahan utama yang dialami Waduk Kedung Ombo adalah sedimentasi TSS yang tinggi dan berakibat juga adanya pencemaran kesuburan air pada peningkatan klorofil-a. Data Kementerian Lingkungan Hidup (2010) menyatakan bahwa Waduk Kedung Ombo mengalami penyusutan air hingga 42,67% dari volume air normal (723,16 juta m3). Data ini mempertegas Data Kementerian Pekerjaan Umum per Februari 2008 yang menyatakan volume ketersediaan air di Waduk Kedung Ombo hanya setengah dari yang direncanakan. Pemantauan tingkat kualitas perairan Waduk Kedung Ombo saat ini masih dilakukan dengan pengamatan sampel kualitas air secara uji laboratorium pada beberapa stasiun pengamatan. Teknik ini untuk bentangan wilayah yang cukup luas memerlukan waktu dan biaya yang cukup besar. Teknologi penginderaan jauh dapat memberikan solusi untuk pengamatan kualitas air pada bentangan daerah yang luas karena menggunakan citra satelit memiliki cara pemrosesan yang tidak rumit dan biaya yang cukup murah. Teknologi penginderaan jauh dapat mengindentifikasi dan menganalisis hasil perekaman karakteristik spektral air dengan parameter-parameter kualitas air. Dimana dengan menggunakan metode-metode yang tepat nantinya mampu menampilkan kualitas air Waduk Kedung Ombo sesuai dengan yang diharapkan. Salah satu data citra satelit yang mampu dimanfaatkan adalah citra satelit Landsat-8. Pengamatan citra satelit Landsat-8 dengan algoritma TSS dan klorofil-a mampu memberikan informasi tentang perubahan kualitas air. Hasil dari penelitian ini menunjukkan kualitas perairan Waduk Kedung Ombo periode 2013-2018 masih memenuhi baku mutu pencemaran. Ini ditunjukkan dari nilai parameter TSS masih di dominasi kelas memenuhi baku mutu selalu diatas 95% dari total perairan pada semua tahun dan dari parameter klorofil/kesuburan air masih didominasi kelas oligotrof selalu diatas 90 % dari total perairan pada semua tahun.
GENERATING BOUGUER ANOMALY MAP FROM AIRBORNE GRAVITY DATA (A CASE STUDY IN SOUTH EAST SULAWESI)
Authors: Sabri Laode M , Sudarsono Bambang , Jamal Jamal , Mawardi Sonny 
Published: September 2022

Terrestrial measurements can provide accurate gravity data, but it is costly and time-consuming for large and remote area. Airborne gravity measurements have actually been carried out in Indonesia since 2008 by Technical University of Denmark (DTU) in collaboration with the Geospatial Information Agency (BIG). Purpose of the project was to develop a geoid model used for converting elevations from GPS/GNSS measurements that refers to ellipsoid to orthometric elevations that refer to sea level. The data can actually be explored so that it can be used for geophysical and other geoscience purposes, but the data must be carefully treated and extracted into observational gravity data. This study aims to improve the accuracy of gravity airborne data to produce an accurate complete Bouguer anomaly map. The data used in this study were airborne gravity data over Province of Southeast Sulawesi collected on September 29, 2008 to October 1, 2008. Variation in flight height at the time of consecutive data introduced new horizontal acceleration vector. It must be treated as a noise in the measurement of gravity data. The first stage of processing was to eliminate noise due to aircraft acceleration. Gravity data measured in aircraft conditions accelerating more than 5 m.s-2 were eliminated. In this stage, the gravity data were reduced from 64481 observation points to 4900 observation points. The second stage of processing was low pass filtering to eliminate the remaining surges in gravity data. Airborne gravity data that have been snooped and filtered were then applied to calculate the complete Bouguer anomaly. Visually, a complete Bouguer anomaly map through the enhancement process produced a finer map compared to maps from airborne gravity data without enhancement. Comparison of airborne Bouguer anomaly map and terrestrial Bouguer anomaly maps of Kendari sheet showed a correlation of more than 83%. The conclusion of this study was that the enhancement of the airborne data significantly increases the accuracy and reliability of the airborne gravity data for generating a complete bouguer anomaly map. The results of this study also indicated that the airborne archive data has the potential to be used for geophysical and geosciences purposes in Southeast Sulawesi and Indonesia.

Abstract
This article connects the concept of ›give and take‹ in medieval societies with detailed analyses of the rhetorical figures chiasmus and parallelism. It suggests that the structure of ›give and take‹ can be seen as reflected in the text structure. Three Middle-High-German narratives are analyzed: ›Lanzelet‹, ›Willehalm‹ and ›Straßburger Alexander‹, representatives of the trois matières. The article shows that the stylistic devices with which gifts are negotiated differ in detail from text to text, but also that figures of syntactic and semantic similarity and mirroring are used consistently across the texts.
