Zarządzanie marketingowe w świetle idei postmodernistycznych
Authors: Sułkowski Łukasz
Published: February 2022

Autor proponuje przyjrzeć się podstawowym założeniom rodzącego się nurtu marketingu postmodernistycznego. Podejście postmodernistyczne zaczęło rozpowszechniać się w marketingu na przełomie lat 80. i 90. pod wpływem idei społeczeństwa sieciowego i konsumeryzmu. Mimo programowej wieloznaczności tego nurtu wyróżnić można kilka cech postmodernizmu, które zostaną odniesione do marketingu, jak choćby: relatywizm epistemologiczny i kulturowy, posttayloryzm i postfordyzm, hiper rzeczywistość, subiektywizm i partykularyzm, konsumeryzm.
Dlaczego kryzys nie musi prowadzić do rozwoju
Authors: Pasieczny Jacek
Published: February 2022

Jest potwierdzone, że reakcja na kryzys uruchamia mechanizmy rozwoju, które uaktywniają procesy prowadzące do następnego kryzysu. W ten sposób powstają cykle koniunkturalne w gospodarce. Cyklicznie rozwija się również wiele firm. Fazy rozwoju oddzielone są cyklicznie występującymi kryzysami. Autor w artykule przedstawia, że ta ogólna prawidłowość nie dotyczy jednak wszystkich przedsiębiorstw.
Relacje między kulturą organizacyjną a strukturą w świetle badań szczecińskich przedsiębiorstw
Authors: Gadomska Katarzyna , LozanoPlatonoff Alberto , Sysko-Romańczuk Sylwia
Published: February 2022

Jak wynika z zaprezentowanych w artykule wyników badań, kultura organizacyjna może determinować przyjmowanie określonych rozwiązań organizacyjnych, ale gdy sytuacja tego wymaga, struktura może zawierać odpowiednie bodźce motywujące do zmiany nieodpowiednich zachowań, czyli modyfikacji tych wyróżników kultury, które ograniczają sprawność procesów zarządzania. Bardzo istotną rolę w tym procesie odgrywa kadra kierownicza. Jest to rola pośrednika, który z jednej strony może wpływać na ukształtowanie odpowiednie struktury formalnej, a z drugiej - starać się upowszechniać właściwe wzorce zachowań.

Kierownik na rozdrożu - uwagi wcale nie do śmiechu
Authors: Chełpa Stanisław
Published: February 2022

"Wojna" i "walka" to pojęcia, które często i w sposób dość swawolny używane są do opisu rzeczywistości organizacji gospodarczych. Jeśliby te środki retoryczne miałyby być trafne, z jakimi może łączyć się to konsekwencjami? Stosowany przeze mnie tryb warunkowy, który należy określić jako gdybanie, jest celowy. Nie chcę bowiem formułować diagnoz, ani też wynikających z nich dyrektyw postępowania. "Diagnozy stawia się - jak twierdzi poeta A. Zagajewski, gdy się jest bardzo młodym i ambitnym, potem przychodzi czas już tylko na medytację i - co najwyżej - niepokój, któremu czasem towarzyszy coś w rodzaju chichotu" [21, s. 30]. Rozważmy więc wspólnie kilka kwestii ważnych dla "wojennych" zachowań kierowniczych.

Wybrane zastosowania rachunku aktualizacji
Authors: Wójcik Juliusz
Published: February 2022

W artykule przedstawiono dwa przykłady zastosowania rachunku aktualizacji. Są to kredyt składany i oscylator. Cechą wspólną tych przykładów jest wpływ wielkości stopy procentowej na efektywność działań. O ile kredyt składany służy do realizacji projektu inwestycyjnego, to oscylator jest niewątpliwie działaniem szkodliwym - umożliwia wyprowadzenie z systemu bankowego dużego kapitału.

Published: February 2022

Background: Nasopharyngeal cancer (NPC) patients have high risk of cachexia. It is important to notice cachexia parameters in the beginning of their treatment in order to predict and anticipate unexpected outcomes. This study aimed to describe the profile of advanced stage NPC patient receiving first chemotherapy, especially in cachexia parameters and dietary intakes.
Methods: A cross-sectional study was conducted involving advanced stage of NPC patients who would receive their first chemotherapy aged 20-70 years. Subjects with distant metastatic, acute infection, history of past chemotherapy or radiotherapy, were excluded. Parameters of cachexia being studied were inflammation markers (NLR and CRP level), anorexia and fatigue scores, body composition (fat and muscle mass) and hand grip strength (HGS), meanwhile dietary intakes were energy and protein. Frequency distribution, descriptive statistic, and Pearson correlation test were used in data analyses.
Results: Forty-three subjects were participated. Average age was48.1±9.8 years old and 63% were males. NLR and CRP level were high, i.e.4.8±5.0 and 13.3±20.6 mg/dL, respectively. Anorexia and fatigue scores were 32.4±9 and 35.9±11.8, respectively, with 70% subjects were anorexic and 30% subjects experienced severe fatigue. Less than 20% were malnourished but 35% subjects had central obesity and 37% subjects classified to have very high fat mass. Most subjects had low muscle mass (77%) and classified to have weak HGS (77%). Energy and protein intakes were 26.7±8.9 kcal/kgBW/d and 1±0.4 g/kg BW/d respectively. Some variables had strong correlation (r≥0.80), i.e. BMI with visceral fat (r=0.94), fat with muscle mass (r=-0.89), energy with protein intakes (r=0.80), and moderate correlation (r=0.60–0.79) between anorexia and fatigue scores.
Conclusions: Advanced stage of NPC patients receiving first chemotherapy had high inflammation status, anorexia and fatigue. Many subjects had low muscle mass and weak HGS. BMI with visceral fat, fat with muscle mass, energy with protein intake, were strongly correlated.

Published: February 2022

Essential thrombocythemia (ET) is an extremely rare myeloproliferative neoplasm (MPN) which is characterized by persistent, non-reactive thrombocytosis (> 450 X 109/L) and an increased risk for thrombotic events.These patients have an increased risk of both hematological and non-hematological malignancies however the risk of breast cancer in MPN is not increased in comparison to general population. We hereby present an extremely unusual case of ET in a 38 years old female (diagnosed with breast cancer), which came to light on routine pre-surgical work up of the patient.Diagnosis was confirmed on bone marrow aspiration clubbed with JAK 2 mutation. Patients with ET have an increased risk of thrombosis thereby it becomes challenging for the clinician to operate on a coexistent solid tumor. On extensive literary search, there was a single case of coexistent Breast Cancer and Essential Thrombocythemia and we are reporting second such coexistence to the best of our knowledge.

Published: February 2022

Percutaneous dilatational tracheostomy (PDT) is an increasingly popular method with several advantages, such as being able to perform at bedside with a simple kit, with a less number of medical staff and less amount of time. PDT is easier to perform, offers less bleeding risks and post-operative infection rates compared to conventional surgical tracheotomy. However, PDT is being performed more in the pulmonology and intensive care medicine than in otolaryngology. Herein, we introduce PDT and share our experiences, hoping otolaryngologists use our procedure more.

Published: February 2022

Background: The selection of superior genotypes and adapted to the edaphoclimatic conditions of the region of the introduction produces gains in productivity for forest stands. The objective of this study was to select progenies of Pinus spp. planted in Lavras, Minas Gerais (MG), Brazil. Methods: The experimental site was located on dystrophic Haplic Cambisol. The progeny test was designed as a randomised complete block with 30 replicates and single plot. The treatments corresponded to one progeny of Pinus massoniana, three Pinus caribaea var. bahamensis and 33 Pinus caribaea var. hondurensis arranged with a 3x3 m spacing. The traits height (H), diameter at breast height (DBH) and crown projection area (CPA) were measured at 36 months of age. Results: The results showed that heritability in the narrow sense was 0.24 for DBH, 0.27 for H and 0.50 for CPA. The DBH and H traits showed a high-magnitude positive correlation. The P7, P15, P27, P31 and P33 progenies showed better performance than the other progenies for the evaluated traits. Direct and indirect selection showed similar gains, which favors the use of indirect selection; i.e., when selecting progenies for DBH, progenies with better performance in H are also selected. Additionally, DBH may be used at advanced ages given the difficulty of measuring height. The progeny of Pinus caribaea var. hondurensis showed superior performance compared with Pinus caribaea var. bahamensis and Pinus massoniana for the region of Lavras, MG. Conclusions: This study suggests the possibility of expanding the production of Pinus caribaea var. hondurensis in the region of Lavras with progenies P7, P15, P27, P31 and P33, because in the initial assessments they showed greater adaptability to the edaphoclimatic conditions. Nevertheless, performing a future selection with the aim of evaluating resin production is recommended.

Published: February 2022

A presente pesquisa incide sobre a problemática da evasão escolar, e tem como objetivo principal, conhecer os fatores que levam à evasão dos alunos nos três módulos que compõem o curso Técnico de Administração da ETEC José Martimiano da Silva de Ribeirão Preto - SP - Brasil, do período vespertino, nos anos de 2016 até 1º semestre de 2018. Após o levantamento no sistema da Secretaria Acadêmica da escola, optou-se pela metodologia da pesquisa de campo, com abordagem qualitativa, tendo como técnica a entrevista semiestruturada. Os resultados das entrevistas, de acordo com duas categorias principais construídas acerca dos elementos envolvidos na evasão escolar, indicam os motivos da escolha do curso e motivos da evasão do curso técnico em administração e, no âmbito dessas categorias, foram elencadas as subcategorias. Observou-se que o fator social e econômico dos alunos sobressai como primeiro ponto na evasão do curso, tornando vulneráveis as ações da instituição em busca de soluções para o controle dos números apresentados na pesquisa. Outro fator é o período do curso e a localização da escola que, por fatores educacionais e governamentais, contribuem para esses números. E, por fim, o fator socioeconômico da região, impactando nas decisões dos alunos para capacitação e desafios que o mercado de trabalho impõe. Concluiu-se que a ETEC deve dar especial atenção à evasão no período vespertino, no que diz respeito à dependência de disciplina e excesso de faltas, uma vez que as demais causas de evasão identificadas entre os participantes da pesquisa não dizem respeito ao contexto interno da escola, mas são atribuídos a fatores considerados “positivos” do ponto de vista dos estudantes, uma vez que remetem a fatores como conseguir emprego, estágio, ingressar em cursos superiores ou mudança de turno de estudo.

Com o grande crescimento das indústrias dos diversos segmentos como o sucroalcooleiro, papel e celulose, alimentos, bebidas e outros, as empresas vêm investindo e buscando cada vez mais novas tecnologias para se tornarem cada vez mais competitivas no mercado. O processo de fundição, que proporcionou a evolução e desenvolvimento da metalurgia desde há muito tempo, ainda continua sendo o principal processo utilizado na fabricação de peças devido à sua grande versatilidade em obtenção de materiais com boas propriedades mecânicas e também pela possibilidade de adicionar elementos de liga nestes materiais fundidos. Entretanto para um melhor desempenho em serviço, algumas peças devem ser revestidas. Este trabalho tem por objetivo estudar o comportamento do aço fundido ASTM A217- Gr WC9 quando submetido ao processo de soldagem com revestimento duro, com e sem o tratamento de alívio de tensões. O processo de soldagem com revestimento duro, também chamado de Hardfacing, atualmente não se aplica em recuperações localizadas por se desconhecer os efeitos causados por falta do alívio de tensões. Sendo assim, hoje temos que retirar toda a solda já depositada, quando há ocorrência de trincas, poros ou inclusões não metálicas, que atrapalha a qualidade exigida em projeto. Aplica-se solda de metal base novamente, e então é realizada a usinagem do chanfro para a nova soldagem por revestimento duro. Para as avaliações das propriedades foram realizados ensaios de microdureza, macrografia e líquido penetrante.

O fornecimento de chapas laminadas de aço estrutural no Brasil, no período de 1980 a 2005 era na totalidade feito por distribuidores brasileiros de produtos siderúrgicos, os quais são representantes de duas das principais usinas siderúrgicas nacionais: COSIPA e Usiminas. Neste período, cada produto era fabricado atendendo à uma única especificação. Atualmente, com a competitividade, a globalização de mercado, o aumento de produtividade, e a redução de custos e de preço ao consumidor e de excelência em qualidade, evoluiu-se na efetividade de fabricação desses aços de modo que se produza chapas laminadas que possam atender simultaneamente à duas ou três especificações diferentes, desde que, as especificações convirjam à parâmetros que permitam, através de cuidadosos controles, permitam a fabricação destes materiais. Este novo conceito que antes era notado em produtos de outros países, passou a ser praticado por usinas siderúrgicas nacionais como a Gerdau e a Usiminas. Esta nova condição despertou uma curiosidade técnica em avaliar o comportamento deste tipo de material, submetendo-se os certificados da qualidade à uma comparação apurada em suas análises químicas e às propriedades mecânicas obtidas. Assim, neste trabalho, foram avaliados quatro certificados da qualidade de fabricação destes materiais, considerando os valores prescritos pelas respectivas especificações neles contidas, sendo elas, ASTM-A36, ASTM- A131 Gr. A e ASTM- A283 Gr. C. Verificou-se que existe uma equivalência próxima entre os valores especificados, considerando que as faixas especificadas dos principais elementos presentes nestes aços, o carbono e o manganês, elementos estes que refletem diretamente nas propriedades mecânicas, são bem amplas, permitindo-se então, em uma única carga de fabricação (carga forno), conseguir preparar um único material de forma a atender satisfatoriamente as três especificações, ASTM- A36, ASTM- A131 GR. A e ASTM- A283- GR. C.

UD. Elindo Jaya is a home industry engaged in making bags. This home industry manages raw materials into finished goods. Inventory is important for the home industry. Availability of raw materials in the right amount and time is a support for the smooth production process and can avoid shortages and excess of raw materials that can affect costs incurred. The problem that is formulated is how many raw materials for each order and when the components of these raw materials must be available in the warehouse in the right amount and time. The purpose of this study is to determine the amount of raw materials per order so that effectiveness can be achieved and to know the amount and time that must be available for the smooth running of the production process. Material requirement planning (MRP) is a method for knowing the planning of the production process and the raw material requirements for each component and determining the lead time for orders. From the data processing analysis carried out based on the MRP method, the raw material for producing 1000 bags requires 2.2 rolls of varing material on the 3rd day, 2000 sewing threads on the 4th day, 5.5 miniso material on the 3rd day, 2,2 zipper rollers on the 4th day, and 100 M of the rante accessories on the 4th day.
NCMW: A Python Package to Analyze Metabolic Interactions in the Nasal Microbiome
Authors: Glöckler Manuel , Dräger Andreas , Mostolizadeh Reihaneh
Published: February 2022

The human upper respiratory tract is the reservoir of a diverse community of commensals and potential pathogens (pathobionts), including Streptococcus pneumoniae (pneumococcus), Haemophilus influenzae, Moraxella catarrhalis, and Staphylococcus aureus, which occasionally turn into pathogens causing infectious diseases, while the contribution of many nasal microorganisms to human health remains undiscovered. To better understand the composition of the nasal microbiome community, we create a workflow of the community model, which mimics the human nasal environment. To address this challenge, constraint-based reconstruction of biochemically accurate genome-scale metabolic models (GEMs) networks of microorganisms is mandatory. Our workflow applies constraint-based modeling (CBM), simulates the metabolism between species in a given microbiome, and facilitates generating novel hypotheses on microbial interactions. Utilizing this workflow, we hope to gain a better understanding of interactions from the metabolic modeling perspective. This article presents nasal community modeling workflow (NCMW)—a python package based on GEMs of species as a starting point for understanding the composition of the nasal microbiome community. The package is constructed as a step-by-step mathematical framework for metabolic modeling and analysis of the nasal microbial community. Using constraint-based models reduces the need for culturing species in vitro, a process that is not convenient in the environment of human noses.

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease, and ALS incidence is increasing worldwide. Patients with ALS have respiratory failure at the disease’s end stages, leading to death; thus, the lung is one of the most affected organs during disease progression. Tissue stiffness increases in various lung diseases because of impaired extracellular matrix (ECM) homeostasis leading to tissue damage and dysfunction at the end. According to the literature, oxidative stress is the major contributor to ECM dysregulation, and mutant protein accumulation in ALS have been reported as causative to tissue damage and oxidative stress. In this study, we used SOD1G93A and SOD1WT rats and measured lung stiffness of rats by using a custom-built stretcher, where H&E staining is used to evaluate histopathological changes in the lung tissue. Oxidative stress status of lung tissues was assessed by measuring glucose 6-phosphate dehydrogenase (G6PD), 6-phosphogluconate dehydrogenase (6-PGD), glutathione reductase (GR), glutathione s-transferase (GST), catalase (CAT), and superoxide dismutase 1 (SOD1) levels. Western blot experiments were performed to evaluate the accumulation of the SOD1G93A mutated protein. As a result, increased lung stiffness, decreased antioxidant status, elevated levels of oxidative stress, impaired mineral and trace element homeostasis, and mutated SOD1G93A protein accumulation have been found in the mutated rats even at the earlier stages, which can be possible causative of increased lung stiffness and tissue damage in ALS. Since lung damage has altered at the very early stages, possible therapeutic approaches can be used to treat ALS or improve the life quality of patients with ALS.
Emerging Therapeutic Potential of Mesenchymal Stem Cell-Derived Extracellular Vesicles in Chronic Respiratory Diseases: An Overview of Recent Progress
Authors: Ma Yiming , Liu Xiangming , Long Yingjiao , Chen Yan
Published: February 2022

Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) are able to carry genetic and protein goods to mediate the interaction between MSCs and target cells. Recently, more and more researches have focused on the therapeutic role of MSC-EVs in chronic respiratory diseases. In this review, we summarize the cumulative strategies and mechanisms of MSC-EVs in treating chronic respiratory diseases. This review suggests that MSC-EVs may serve as a novel cell-free-based therapy for chronic respiratory diseases, including COPD, asthma, pulmonary fibrosis, and pulmonary arterial hypertension. In current studies of chronic respiratory diseases, umbilical cord and bone marrow are main sources of MSC-EVs, while adipose tissue, lung, and induced pluripotent stem cells are also applied. Isolation methods of MSC-EVs in treating chronic respiratory diseases involve ultracentrifugation, exosome extraction kits and anion-exchange chromatography. Intratracheal delivery and intravenous administration are the most widely used routes of MSC-EVs. MSC-EVs are able to transfer microRNAs and protein to target cells and further magnify the therapeutic effects.
Acknowledging and Supplanting White Supremacy Culture in Science Communication and STEM: The Role of Science Communication Trainers
Authors: Callwood Karlisa A. , Weiss Marissa , Hendricks Rose , Taylor Temis G.
Published: February 2022

Racism remains a root cause of underrepresentation of Black, Indigenous, and Latinx scholars across STEM. It also contributes to a lack of diversity in science communication, the types of science stories that are told, and the communities science communicators seek to engage. Racism is omnipresent in STEM, from education to research to science communication (SciComm), because STEM institutions operate within a culture systematically privileging Whiteness, i.e., a White supremacy culture (WSC), that dictates the norms and practices that most in these fields heedlessly accept and replicate. In this Perspective, we acknowledge the ways in which SciComm and SciComm training perpetuate WSC and examine how SciComm trainers can use their power to dismantle it. SciComm trainers pioneer new methods of sharing ideas and influence the culture of STEM, so are uniquely situated to bring about systemic change to address these problems in SciComm, STEM, and society, starting with four core themes for action: (1) Authentic Interrogation, Acknowledgment, and Accountability; (2) Representation; (3) Culturally Responsive Practice; and (4) Inclusion. We also describe our current work, which builds upon the Key Traits of Inclusive SciComm identified by leaders in the field, to co-create a framework to guide authentic, culturally competent, and inclusive SciComm. The draft framework integrates the Key Traits across spheres of influence (e.g., self, interpersonal, community, institution, society: politics and culture), with the ultimate goal of using SciComm to supplant WSC across these spheres of influence, with new co-created norms centering minoritized scholars, science communicators, and audiences in STEM.

Background

Right ventricular (RV) three-dimensional (3D) strains can be measured using novel 3D RV analytical software (ReVISION). Our objective was to investigate the prognostic value of RV 3D strains.

Methods

We retrospectively selected patients who underwent both 3D echocardiography (3DE) and cardiac magnetic resonance from January 2014 to October 2020. 3DE datasets were analyzed with 3D speckle tracking software and the ReVISION software. The primary end point was a composite of cardiac events, including cardiac death, heart failure hospitalization, or ventricular tachyarrhythmia.

Results

341 patients were included in this analysis. During a median of 20 months of follow-up, 49 patients reached a composite of cardiac events. In univariate analysis, 3D RV ejection fraction (RVEF) and three 3D strain values [RV global circumferential strain (3D RVGCS), RV global longitudinal strain (3D RVGLS), and RV global area strain (3D RVGAS)] were significantly associated with cardiac death, ventricular tachyarrhythmia, or heart failure hospitalization (Hazard ratio: 0.88 to 0.93, p < 0.05). Multivariate analysis revealed that 3D RVEF, three 3D strain values were significantly associated with cardiac events after adjusting for age, chronic kidney disease, and left ventricular systolic/diastolic parameters. Kaplan-Meier survival curves showed that 3D RVEF of 45% and median values of 3D RVGCS, 3D RVGLS, and 3D RVGAS stratified a higher risk for survival rates. Classification and regression tree analysis, including 22 clinical and echocardiographic parameters, selected 3D RVEF (cut-off value: 34.5%) first, followed by diastolic blood pressure (cut-off value: 53 mmHg) and 3D RVGAS (cut-off value: 32.4%) for stratifying two high-risk group, one intermediate-risk group, and one low-risk group.

Conclusions

RV 3D strain had an equivalent prognostic value compared with 3D RVEF. Combining these parameters with 3D RVEF may allow more detailed stratification of patient's prognosis in a wide array of cardiac diseases.
Virtual Reality Exposure Therapy for Treating Social Anxiety: A Scoping Review of Treatment Designs and Adaptation to Stuttering
Authors: Chard Ian , van Zalk Nejra
Published: February 2022

Virtual Reality Exposure Therapy (VRET) has been shown to be an effective technique for reducing social anxiety. People who stutter are at greater risk of developing heightened social anxiety. Cognitive behavior therapy protocols have shown promise in reducing social anxiety in people who stutter, but no studies have investigated VRET targeting social anxiety associated with stuttering. The aim of the current review is to provide an overview of VRET techniques used to treat social anxiety and insights into how these techniques might be adopted in the case of comorbid stuttering and social anxiety. Twelve studies were reviewed to understand key distinctions in VRET protocols used to treat social anxiety. Distinctions include exercises targeting public speaking vs. general social anxiety, computer-generated virtual environments vs. 360° video, and therapist guided vs. automated VRET. Based on the review findings, we propose how certain features could be applied in the case of stuttering. Virtual therapists, inhibitory learning techniques and integration into speech therapy may be suitable ways to tailor VRET. Regardless of these different techniques, VRET should consider the situations and cognitive-behavioral processes that underlie the experience of social anxiety amongst people who stutter.
