Virtual machine placement in energy aware load balancer using fog classifier
Authors: Selvaganapathy S. , Chinnadurai M. 
Published: December 2023

AbstractCloud datacenter carries huge volume of data and tasks which is allocating resources to multiple workstations. Most of the cloud services are operating service level agreement (SLA) placements. During execution datacenter emits carbon and makes the energy. So operation cost always consideration fact. We need to address this challenge by using energy aware load balancer. This load balancer can be fixed in Virtual Machines (VM) and Classifier is required for selecting VMs. Employing the VMs is very important factor so fog enabled services is required for distributed geo physical load balancer with energy efficiency. In this paper we propose offloading VM services and Fog classifier for load balancing the cloud services. Placing the VM from one host to another we use Host Load Balancer with Energy Aware placement algorithm. In this case dynamical cloud environment can be tested and compare the host results. This is empirical approach for place the VMs without compromising the users. The simulations are done by using CloudSim and TensorFlow is used of generating deep belief network model for preparing VM placement. Our proposed method achieves 96% energy efficiency with minimum migration cost. The results are compared with existing placement methods based on active host availability.
The role of SVOCs in the initial film formation and soiling of unvarnished paintings
Authors: Grøntoft Terje , Cutajar Jan Dariusz 
Published: December 2023

Abstract
In recent years increased research efforts and environmental improvements have been directed towards the preventive conservation of the monumental, unvarnished oil paintings on canvas (1909–1916) by Edvard Munch (1863–1944) housed in the University of Oslo Aula. Surface soiling of the paintings has been a documented issue since their display, and the modern-day effect of air-borne particulates and gases on the painting surfaces remains hitherto undocumented. For the first time in the Aula, this study has measured the in-situ time-dependent mass deposit of air pollution onto vertical surfaces over the period of one year (2021–2022). Concomitant measurements of the concentrations of ozone (O3) and nitrogen dioxide (NO2) were also taken, to complement periodic data from 2020. The mass deposit was measured through incremental weight changes of Teflon membrane filters, and quartz filters for analysis of elemental/organic carbon (EC/OC), whilst the gaseous pollutants were measured using passive gas samplers. Indoor-to-outdoor ratios (I/O) for O3 were noted to be higher than those suggested by earlier data, whereas NO2 I/O ratios were found to be lower, indicating a stronger oxidising atmosphere in the Aula. Just over half of the deposited mass on the quartz filters was found to be OC, with no EC detected. Surprisingly, an overall decrease in the mass deposit from three to twelve months was measured on the Teflon membrane filters. It was hypothesised, based on models reported in the literature, that the source of the OC on the filters was mainly gaseous, semi-volatile organic compounds (SVOCs), which were present in an adsorption/desorption equilibrium that was dependent on possible SVOC emission episodes, relative humidity levels, gaseous oxidative reactions and the particulate matter deposit. A simple mathematical model is proposed to rationalise the observed mass deposits on the filters, together with a discussion of uncertainties affecting the measurements. The hypothesis preliminarily indicates the possible and previously unconsidered role of SVOCs on the initial film formation of soiling layers on the Aula paintings, and could bear implications for their monitoring in the preventive care of unvarnished oil paintings on canvas.
Meta-analysis of the survival rate and postoperative infection rate of primary and secondary implants after vascularized fibula transplantation for reconstruction of jaw defects

Published: December 2023

Abstract
Objectives
Vascularized fibula flap transplantation is the most effective and common method to repair the jaw defects. In addition, implantation is the first choice to restore dentition on the graft fibula. Implants are usually implanted at least 6 months after fibula transplantation. Primary implantation of implants during surgery can restore the dentition earlier, but whether this method can achieve the same restorative effect as secondary implantation is still uncertain. This article aims to compare the survival rate and complications between primary and secondary implantation through meta-analysis.

Methods
This meta-analysis was conducted according to PRISMA protocol and the Cochrane Handbook of Systematic Reviews of Interventions. According to the inclusion and exclusion criteria, we selected the PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Chinese BioMedical Literature Database (CBM) according to established inclusion and exclusion criteria. The Newcastle–Ottawa Scale (NOS) was used to assess the quality of the included studies. Meta-analysis was conducted to compare the survival rate and postoperative infection rate of primary and secondary implantation.

Results
Seven studies were involved in our research, involving 186 patients. Five of the studies detailed implant success in 106 patients (primary implantation 50, secondary implantation 56), and four studies documented infection after implantation in 117 patients (primary implantation 52, secondary implantation 65); the survival rate of the primary implantation was 93.3%, and the incidence of postoperative infection was 17.3%. The survival rate of the secondary implantation was 93.4%, and 23.1% had postoperative infection. Meta-analysis showed that there was no significant difference in the survival rate between primary implantation and secondary implantation, OR = 0.813 (95% CI 0.383–1.725, P = 0.589 > 0.05), and there was no significant difference in the incidence of postoperative infection, OR = 0.614 (95% CI 0.239–1.581, P = 0.312 > 0.05).

Conclusions
Based on the results of this study, the research found no significant difference in the survival rate or infection rates between primary and secondary implantation. After appropriate indications selection, primary implantation can be used to reconstruct the dentition with less waiting time, reduce the impact of radiotherapy, and bring a higher quality of life for patients.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned coprimary or secondary analyses are not yet available. Clinical trial updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported. The LYMA trial demonstrated the benefit of rituximab maintenance (RM) in first-line young patients with mantle-cell lymphoma. In this prolonged follow-up of 7.5 years (95% CI, 7.4 to 7.7) from inclusion, the median progression-free survival (PFS) and overall survival (OS) for the full population were not reached (NR) with a 7-year PFS of 55.5% (95% CI, 49.5 to 61) and OS of 69.5% (95% CI, 63.8 to 74.5). The EFS remained statistically superior in favor of RM (median NR v 5.8 years, P < .0001; HR, 0.39 [95% CI, 0.52 to 0.6] and 7-year estimate, 76.2% versus 46% for RM and observation, respectively). Similarly, RM prolonged PFS (estimated PFS at 7 years, 78.5% v 47.4% and HR, 0.36 [95% CI, 0.23 to 0.56] for RM and observation, respectively, P < .0001). The 7-year OS estimate was 83.2% versus 72.2%, respectively ( P = .088, HR, 0.63 [95% CI, 0.37 to 1.08]). Cause of death was not significantly distinct between the two groups, with lymphoma being the leading cause with a very low rate of infection-related death. Overall, the PFS benefit of RM after autologous stem cell transplantation remains after 7-year follow-up, and RM was not associated with an increase in infection-related mortality, making this strategy a safe standard of care with long-term follow-up.
Bardoxolone Methyl Ameliorates Chemotherapy-Induced Neuropathic Pain by Activation of Phosphorylated Nuclear Factor Erythroid 2-Related Factor 2 in the Dorsal Root Ganglia
Authors: Kim Hee Kee , Wang Qi , Hwang Seon-Hee , Dougherty Patrick M. , Wang Jing , Abdi Salahadin 
Published: December 2023

BACKGROUND:
Many chemotherapeutic drugs, including paclitaxel, produce neuropathic pain in patients with cancer, which is a dose-dependent adverse effect. Such chemotherapy-induced neuropathic pain (CINP) is difficult to treat with existing drugs. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a major regulator of antioxidative responses and activates phosphorylated Nrf2 (pNrf2). We determined the analgesic effects of bardoxolone methyl (BM), an Nrf2 activator, and the role of pNrf2 on CINP.

METHODS:
CINP was induced in rats by intraperitoneally injecting paclitaxel on 4 alternate days in rats. BM was injected systemically as single or repeated injections after pain fully developed. RNA transcriptome, mechanical hyperalgesia, levels of inflammatory mediators and pNrf2, and location of pNrf2 in the dorsal root ganglia (DRG) were measured by RNA sequencing, von Frey filaments, Western blotting, and immunohistochemistry in rats and human DRG samples. In addition, the mitochondrial functions in 50B11 DRG neuronal cells were measured by fluorescence assay.

RESULTS:
Our RNA transcriptome of CINP rats showed a downregulated Nrf2 pathway in the pain condition. Importantly, single and repeated systemic injections of BM ameliorated CINP. Paclitaxel increased inflammatory mediators, but BM decreased them and increased pNrf2 in the DRG. In addition, paclitaxel decreased mitochondrial membrane potential and increased mitochondrial volume in 50B11 cells, but BM restored them. Furthermore, pNrf2 was expressed in neurons and satellite cells in rat and human DRG.

CONCLUSIONS:
Our results demonstrate the analgesic effects of BM by Nrf2 activation and the fundamental role of pNrf2 on CINP, suggesting a target for CINP and a therapeutic strategy for patients.
Adorno's Problematic Entanglement with Blackness
Authors: Kelly Michael 
Published: December 2023

Abstract
Black aesthetics and Adornian aesthetics both articulate and embody what Hortense Spillers calls the “critical edge” of culture and art, and there is a recent history of Black aestheticians engaging creatively with Adorno. Today, however, any constructive dialogue between these aesthetic traditions depends on whether Adorno's aesthetics can be decoupled from the antiblack racism in the genealogy of Western aesthetics and whether Adorno's negative dialectics can be reconciled to the transformative force of art, as that force is as central in Black aesthetics as is the negative dialectics of art. Critically focusing on Adorno's discussion of “the ideal of blackness” in Aesthetic Theory, this article will argue that such decoupling remains incomplete, that he resolutely did not believe in the transformative force of art, and that these issues are connected, at least in Adorno's case. This article simultaneously demonstrates how Black thinkers—Frederick Douglass, W. E. B. Du Bois, Angela Y. Davis, Fred Moten, Fumi Okiji, and Spillers—have long offered exemplary accounts of art that combine its negative dialectics, critical edge, and transformative force while defying the antiblack racism in Western aesthetics.
Big Data Analytics, Firm Size, and Performance
Authors: Conti Raffaele , de Matos Miguel Godinho , Valentini Giovanni 
Published: December 2023

Big data analytics (BDA) is one of the most important general-purpose technologies. Despite the increasing pervasiveness of BDA across industries and some preliminary evidence indicating that BDA adoption is positively related to firm productivity, previous studies have not fully investigated how BDA benefits actually materialize. To address this question, we explore the effect of BDA on the innovation process, a key determinant of firm productivity. Our findings indicate that both large and small firms can gain from BDA, yet size is a critical organizational attribute determining the most relevant performance gains captured: BDA benefits for value-added are particularly salient for large firms, whereas benefits for sales are more relevant in small firms. This suggests that the relative propensity to use BDA to decrease costs and enhance efficiency through process innovation vs. to increase sales through product innovation is increasing in firm size.

Published: December 2023

Objetivo:analisar elementos motivadores da construção da identidade profissional de enfermeiros do sistema prisional. Método: estudo histórico-social, qualitativo, sob o método de triangulação de fontes orais e documentais coletados de maio a dezembro de 2020, iluminado pelo referencial foucaultiano. Protocolo de pesquisa aprovado pelo Comitê de Ética e Pesquisa da instituição signatária. Resultados: a realização de concurso público para o sistema prisional foi motivada pela aquisição de estabilidade. Os enfermeiros concursados eram despreparados para cuidar de pessoas presas. A disciplina e os poderes exercidos pelos guardas e presos surpreenderam estes enfermeiros, que precisaram se adaptar ao sistema num contexto social marcado pela violência urbana. Considerações finais: destaca-se, na construção da identidade destes profissionais, a capacidade para contornar medos e inseguranças, exercício de poder disciplinar e normatização do cuidado para o enfrentamento do cotidiano do trabalho. Emerge a necessidade de capacitação de enfermeiros nesta área na formação profissional.

Cel pracyCelem artykułu jest prezentacja wyników badań dotyczących miejsca i roli celów zarządczych stosowanych od 2016 roku w procesach zarządzania spółkami komunalnymi w Polsce. Istotną uwagę autorzy poświęcili celom ekonomicznym i społecznym, w szczególności analizie znaczenia tych celów w spółkach.Materiał i metodyPodstawową metodą badawczą była analiza dokumentów – treści uchwał podmiotów uprawnionych do wykonywania prawa udziałowych. Łącznie zbadano treści uchwał podejmowanych w każdym roku w 124 spółkach w latach 2017-2023.WynikiWyniki wskazują na dominację celów ekonomicznych i malejący udział celów społecznych wśród celów zarządczych.WnioskiWnioski nie są pozytywne, biorąc pod uwagę to, że spółki te działają w obszarze użyteczności publicznej. Przyczyny tego zjawiska częściowo wynikają z niezbyt fortunnych zapisów ustawy i wieloletnich przyzwyczajeń, w rzeczywistości mają bardziej złożony i wieloaspektowy charakter. Szczególnie niepokojące jest to, że zysk stosowany wcześniej głównie jako miernik ekonomiczny, stał się w świetle przepisów prawa i praktyki gospodarczej – celem działalności, co może przekładać się bezpośrednio na ceny usług spółek komunalnych dla mieszkańców i lokalnych przedsiębiorców. Z kolei malejący udział celów społecznych może m.in. zmniejszać zaangażowanie pracowników oraz ich sprawną i skuteczną współpracę opartą na zaufaniu.

Published: December 2023

ObjectivesRunning a business effectively requires ensuring continuity and regularity of the activity. For this purpose, it is important to effectively and rationally manage inventories and maintain them at various levels of optimality.Material and methodsIn the paper a design of the probabilistic model of reserves is discussed. The objective was an elaboration of the optimal strategy of materials reserves management in the series manufacturing.ResultsThe model has been verified at an attainable scale using the numerical data concerning different assortment of materials in the serial production of furniture. The proposed probabilistic model makes it possible to elaborate the optimal strategy of type R, Z in the management of reserves of based materials of the manufacturing company with large-lot production. The strategy is based on minimal expenses connected with a supply of materials.ConclusionsFor each company to provide good quality services, it is necessary for individual, cooperating enterprises to function efficiently. The so-called "supply chain" is a specific sequence of activities enabling the satisfaction of market demand for a given product. The supply chain consists of companies and plants that are involved in supplying raw materials, processing them into semi-finished products and, ultimately, creating a finished product. The simplest supply chain consists of a company, suppliers and customers. However, it is good to know that many more companies are involved in most production processes, including transport, logistics, finance and IT.

Published: December 2023

ObjectivesThis paper aims to present a synthetic diagnostic tool for assessing wokeism in universities, offering a comprehensive framework derived from an extensive literature review. The purpose is to measure and evaluate the level and impact of wokeism, identifying strengths and weaknesses within university contexts. The framework development involves defining dimensions and indicators of wokeism, collecting and analyzing data through diverse sources like surveys and interviews, scoring and ranking wokeism levels.Material and methodsThis paper presents a synthetic diagnostic tool designed for the assessment of wokeism in universities. It extensively reviews literature on wokeism, offering a framework for the creation of this diagnostic tool. The provided examples demonstrate practical applications for measuring and evaluating the level and impact of wokeism within university settings.ResultsThe paper highlights several limitations and implications that warrant consideration. First, the broad and general definition of wokeism employed might overlook nuanced variations within the movement. Second, reliance on secondary sources and hypothetical data raises concerns about the representation of the actual situation of wokeism in universities. Third, the subjective scoring and ranking system employed may lack the validity and reliability required for a comprehensive assessment.ConclusionsThe paper proposes directions for future research and practice. It recommends refining and operationalizing the definition and measurement of wokeism, testing and validating the tool and framework with primary and empirical data, and applying more objective and rigorous methods for scoring and ranking.
The role of the brand in identifying patterns of the consumer decision-making process on the example purchasing a passenger car
Authors: Jusiuk Paulina Agnieszka 
Published: December 2023

Cel pracyWspółcześnie pięcioetapowy konsumencki proces decyzyjny kończy się na zakupie konkretnej marki produktu. Decydenci przy wyszukiwaniu informacji zazwyczaj mają określone kategorie, jakie podczas rozwiązywania danego problemu decyzyjnego przeszukują. Celem niniejszego opracowania jest sprawdzenie, czy marka produktu ma wpływ na zakres informacji niezbędnych do podjęcia decyzji o zakupie samochodu osobowego. W artykule skupiono się na sprezycowaniu miejsca decyzji w procesie zakupowym, a także uwzględnieniu pozycji marki.Materiał i metodyProcedura badawcza prowadzona była dwuetapowo. W pierwszym kroku zbadano stosunek respondentów względem procesu decyzyjnego, a następnie przy wykorzystaniu tablicy informacji przeprowadzono eksperyment skupiający się na wybraniu przez respondenta produktu. Następnie przy wykorzystaniu podstawowych analiz statystycznych, statystycznego testu nieparametrycznego Manna-Whitney’a, jak również analizy korelacji przeprowadzono wnioskowanie statystyczne.WynikiNa podstawie zrealizowanych analiz stwierdzono, że w przypadku konsumenckiego procesu decyzyjnego odnośnie zakupu samochodu marka jest informacją, po którą badany sięga w pierwszej kolejności. Ponadto konsumenci w celu zaspokojenia określonej potrzeby sięgają po marki dobrze im znane, a co z tym idzie – sprawdzone. Opracowany schemat postpowania konsumentów podczas wyboru samochodu zakłada, że kolejne informacje po jakie sięgają decydenci związane są z ponoszeniem kosztów.WnioskiW dobie panującej inflacji fakt ten nie jest zaskakujący, bowiem jednostki muszą bardzo uważnie i roztropnie gospodarować domowym budżetem. Fakt ponoszenia wysokich kosztów dodatkowych, przy jednoczesnej eksploracji nowej marki samochodu osobowego może doprowadzić do pewnego rodzaju frustracji.
