Effectiveness of a Novel Implementation of the Otago Exercise Program in Rural Appalachia
Authors: Scronce Gabrielle , Zhang Wanqing , Smith Matthew Lee , McCulloch Karen Leigh , Mercer Vicki Stemmons
Published: February 2021

Background and Purpose:

Despite evidence that falls can be prevented with specific exercise interventions such as the Otago Exercise Program (OEP), translation of these programs into practice is limited in rural and medically underserved areas. The Community Health and Mobility Partnership (CHAMP) addresses this problem through a community-based implementation of the OEP in rural Appalachia where medical resources are scarce. The purpose of this study was to examine the effects of the CHAMP on physical performance and balance confidence in community-dwelling older adults.

Methods:

This study was a retrospective analysis of quasi-longitudinal data. Older adults received fall screenings at local senior centers. Those with increased fall risk received individualized OEP home exercises and were advised to return for monthly follow-up visits. Three physical performance measures—Timed Up and Go test (TUG), Four-Stage Balance Test (4SBT), and chair rise test (CRT)—and the Activities-specific Balance Confidence scale (ABC) were assessed at the initial visit (IV) and each follow-up visit. Two groups were created to distinguish participants who returned for their second follow-up (F2) visit within 3 months from those who returned between 3 and 6 months. Within-group change from IV to F2 was calculated using repeated-measures t tests. Repeated-measures 2-way analyses of variance were used to test for main and interaction effects of group and visit.

Results and Discussion:

One hundred thirty CHAMP participants aged 76.1 (SD = 8.1) years demonstrated statistically and clinically significant improvements in the 3 physical performance measures (mean 4SBT: IV 29.5 seconds, F2 31.5 second, P = .001), (mean TUG: IV 12.7 seconds, F2 11.9 seconds, P = .021), (mean CRT: IV 0.258 stands/second, F2 0.290 stands/second, P = .002), but not in balance confidence (mean ABC: IV 62.2, F2 64.4, P = .154). A significant interaction of group by visit for the TUG was observed, suggesting that better TUG performance was associated with quicker return for follow-up.

Conclusions:

Results indicated that program participants improved from IV to F2 in measures related to fall risk.
Efficacy of Traditional Physical Therapy Versus Otago-Based Exercise in Fall Prevention for ALF-Residing Older Adults
Authors: Knott Sky , Hollis Amber , Jimenez Daniel , Dawson Nicole , Mabbagu Eric , Beato Morris
Published: February 2021

Background and Purpose:

Falls are a leading cause of morbidity, mortality, loss of independence, and significant functional decline in aging populations. Effective interventions aimed at reducing the risk of falls, and preventing associated disability and functional decline, are needed to promote the health and wellness of older adults. Recent literature has found that an Otago-based exercise program (OBEP), which incorporates strengthening, balance, and walking, may not only decrease falls and fall risk among community-dwelling older adults but may also be effective among older adults residing in assisted living facilities (ALFs). The purpose of this study is to expand upon current research by comparing the outcomes of an OBEP and traditional physical therapy (TPT) in decreasing falls and the risk of falls among older adults living in an ALF. The authors hypothesized that traditional physical therapy would reduce fall risk and the number of falls in older adults residing in ALFs more than an OBEP.

Methods:

This study conducted a 2-group retrospective chart review of 59 older adults living in an ALF from January 2013 to October 2018 who received either TPT (n = 29) or the OBEP (n = 30). Participants were a mean of 87 years old and were classified at risk for falls by the Tinetti Performance-Oriented Mobility Assessment (POMA). Primary variables included the number of falls prior to intervention, during intervention, and 1 year following intervention, as well as pre- and posttreatment Tinetti POMA scores. Efficacy was examined using multiple linear regression analysis.

Results and Discussion:

Both groups achieved reduced falls and increased POMA scores. Group assignment did not significantly predict performance in key outcome measures, namely the number of falls (P = .199) and Tinetti POMA scores (P = .063) following treatment.

Conclusions:

These findings indicated that both an OBEP and tpt may be effective interventions for reducing falls and fall risk in the ALF setting.
Domains of Balance Training Delivered in Rehabilitation Programs Following Hip Fracture Surgery in Older Adults: A Systematic Review
Authors: Lima Camila Astolphi , Perracini Monica Rodrigues , Funabashi Martha , Weber Sydnie , Beaupre Lauren
Published: February 2021

Background and Purpose:

The aim of this systematic review was to assess the domains and characteristics of balance training (BT) interventions delivered in rehabilitation programs following hip fracture to identify potential treatment gaps.

Methods:

Manual and electronic searches (Web of Science, Medline, EMBASE, CINAHL, and ProQuest) were conducted. We selected randomized controlled trials with older adults following hip fracture surgery that included either specific BT or gait, mobility, or transfer training. Two independent reviewers extracted data and rated the methodological quality using the Physiotherapy Evidence Database scale. A third reviewer provided consensus. Extracted BT data included balance domain, progression, frequency, duration, intensity, level of supervision, setting, and rehabilitation phase.

Results and Discussion:

We included 17 trials from 19 studies; 11 studies were rated as moderate to high methodological quality, but only 8 were considered to have high-quality BT components. Half of the interventions included only one balance domain, with stability during movement being the most commonly included domain. The primary balance progression utilized was reducing hand support. Dual task, anticipatory postural adjustment, reactive strategies, and perceptual training domains were rarely included. Balance training duration and intensity were poorly described. Although most programs were home-based with minimal levels of supervision, a few extended beyond postacute phase of rehabilitation.

Conclusion:

Further consideration should be given to include more challenging BT domains with planned progressions to maximize patient recovery through hip fracture rehabilitation programs.
Prayer and the Art of Literature in Anselm of Canterbury’s Proslogion
Authors: Davis Robert Glenn
Published: February 2021

This article reads the Proslogion of the medieval theologian Anselm of Canterbury as a drama of seeking and finding God. It guides the reader through a process of rhetorical inventio, with all of its attendant risks, pleasures, and discontents. The text opens a space or gap of desire, speaking in the voice of the soul who seeks anxiously to find (invenire) God but turns up only absence. The “I” who speaks and addresses itself to itself and to God learns not to close that gap but to inhabit it, affectively and intellectually, just as the monastic rhetor must, when he directs his inventive activity to God.

The article discusses the functions of the map in the journalism and poetry of Michał Książek (Droga 816, Jakuck, Nauka o ptakach, Północny wschód). The author asserts that the map creates multiple tensions between the sign and reality and releases the emotions which accompany the journey, both in space and time. Książek constantly seeks correspondence between the world of the map and reality, which he merges in his travel narratives and observations.
Strategie dramatyzacji Ulissesa Jamesa Joyce’a
Authors:   Akademia Pomorska w Słupsku, Kozłowski Paweł
Published: February 2021

The article indicates that James Joyce stylizes his novel Ulysses for a drama, and gives a comprehensive analysis of some narrative techniques used in the work. Referring to the most important, narratologically-oriented studies of Ulysses, the author states that limiting the narrator’s competences turns out to be the basic strategy for dramatizing the novel. This assertion leads to the conclusion which has been so far overlooked in the Polish and Anglophone criticism. Using the comparative method, the author draws attention to the specifically dramatic conventions of dialogue transposed into Ulysses. These are devices known from the works of eminent playwrights of modernity, especially Ibsen, Strindberg, Maeterlinck and Chekhov

Goal – identification of conditions for the economic feasibility of repairing units with the restoration of parts in comparison with the repair based on the use of new parts. Research – techno‑economic methods were used, taking into account the changing cost items for technological operations of repairing automobile units in various versions. The limitation was the provision of after‑repair running hours of repaired units, not inferior to the standard operating time of new units. Score/results – the review shows the conditions under which the main quality indicators in the form of wear resistance and fatigue strength of the restored parts, which determine their durability, are not inferior to the development to the limit state of new parts. Originality/value – the cost of restoring individual parts during the repair of units is 8–60% of the price of new products. The conditions of concentration of production with an increase in its volumes are given, which reduces the complexity of the restoration of parts up to two times.

Analysis of runoff deficit using the treshold method for the case of three gauging stations in Slovenia
Authors: Cunja Jan , Kobold Mira , Šraj Mojca
Published: February 2021

This analysis deals with the comparison of volume and duration of runoff deficits using different drought thresholds for the gauging stations Polana on the Ledava, Litija on the Sava, and Kubed on the Rižana Rivers with different climatic conditions for the hydrologically driest years in the period 1960–2016 in Slovenia. Using the threshold method, all events in which discharge fell below a pre-selected threshold value were identified as drought events. Three different values were chosen for the threshold value, namely the mean low periodic discharge sQnp and the percentiles of flow duration curve Q90 and Q80. For each gauging station, the event with the largest deficit volume and duration, as well as the total annual deficit volume and the total duration of drought events for the individual year, were selected using different threshold values. The study’s results demonstrate that the choice of drought threshold can have a great impact on the results of runoff deficit analyses. The absolute values of the duration and volume of the runoff deficits increase with higher threshold values. Also the ratios between the results of the individual years change slightly when the threshold value changes. Regardless of the choice of the threshold, 2003 proved to be the driest year according to all four selected drought characteristics and for all three analysed gauging stations, followed by 1993, 1971, and 2012, respectively. However, drought is a specific phenomenon of a regional character and is reflected differently in the different regions of Slovenia.

Authors: Kutz Alexander , Conen Anna , Gregoriano Claudia , Haubitz Sebastian , Koch Daniel , Domenig Oliver , Bernasconi Luca , Mueller Beat , Schuetz Philipp
Published: February 2021

Objective

While evidence on the interface between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the renin-angiotensin-aldosterone-system (RAAS) is accumulating, clinical data on RAAS peptide alteration among coronavirus disease-19 (COVID-19) patients is missing.

Design and methods

In this exploratory study, we prospectively included adult patients (aged ≥ 18 years) admitted between February 26 and April 30, 2020 to a tertiary care hospital in Switzerland. We assessed the association of an underlying SARS-CoV-2 infection and equilibrium serum levels of RAAS peptides in hospitalized COVID-19 patients 1:1 propensity-score matched with patients suffering from SARS-CoV-2-negative respiratory infections. Subgroup analyses involved stratification for taking RAAS inhibitors.

Results

COVID-19 patients had about 50% lower equilibrium serum RAAS peptide levels as compared with matched controls (angiotensin I: 31.6 vs 66.8 pmol/L, −52.7% (95%CI: −68.5% to −36.9%); angiotensin II: 37.7 vs 92.5 pmol/L, −59.2% (95%CI: −72.1% to −46.3%); angiotensin (1–5): 3.3 vs 6.6 pmol/L, −49.7% (95%CI: −59.2% to −40.2%); angiotensin (1–7): 4.8 vs 7.6 pmol/L, −64.9% (95%CI: −84.5% to −45.3%)). While the plasma renin activity was lower in COVID-19 patients (88.6 vs 207.9 pmol/L, −58.5% (95%CI: −71.4% to −45.6%)), there was no difference of angiotensin-converting enzyme (ACE) and ACE2 plasma activity between the groups. Subgroup analyses revealed a pronounced RAAS peptide profile depression in COVID-19 patients among those not on RAAS inhibitors.

Conclusions

As compared with SARS-CoV-2-negative patients, we found a downregulated RAAS in presence of a SARS-CoV-2 infection. Whether the lower levels of the protective angiotensin (1–5) and (1–7) are linked to adverse outcomes in COVID-19 warrants further investigation.

Організаційна робота філій полягала в заснуванні низових осередків – кружків у населених пунктах, що належали до меж діяльності тієї чи іншої філії. Найуспішнішою у цьому напрямку була діяльність Тисменицької філії. Культурно-освітня робота “Союзу українок” у Товмацькому повіті представлено через влаштування різних свят, урочистих заходів на честь видатних українських письменників, громадських діячів, через організацію і проведення різноманітних освітніх лекцій і курсів для жіноцтва, через налагодження мережі “захоронок” (дитячих садків) та опіку над дітьми з бідних українських сімей. Також у статті показано громадсько-політичну діяльність “Союзу українок” Тов­мач­чини в частині участі союзянок у виборах по польського парламенту. Так само дослідник навів приклади співпраці жіночої організації з іншими українськими культурно-освітніми та економічними товариствами “Просвіта”, “Рідна школа”, “Сільський господар”.

Методологічною основою для написання статті слугували принципи об’єктивності й істо­ризму, діалектичного розвитку, сходження від абстрактного до конкретного, термінологічний і сис­темний. У роботі використано методи аналізу і синтезу, узагальнення та класифікації, архівної та бібліографічної евристики, джерелознавчої критики, проблемно-хронологічний, порівняльно-історичний методи.

Biorefinery review: Wide-reaching products through kraft lignin
Authors: Demuner Iara F. , Colodette Jorge Luiz , Demuner Antonio J. , Jardim Carolina M.
Published: February 2021

This review details the structure of lignin and curates information on the characteristics that this polymer must have for each specific use. Lignin is a by-product of the pulp and paper industry and the second most abundant biopolymer after cellulose. Approximately 50 million tons of lignin are produced worldwide annually, of which 98% to 99% is incinerated to produce steam, process energy. Just 1% to 2% of the lignin, derived from the sulfite pulp industry, is used in chemical conversion to produce lignosulfonates. Biorefining is a promising approach to promote the wider use of kraft lignin. However, using kraft lignin to produce high value-added products is a great challenge, due to its complex structure, low reactivity, and low solubility, which are factors that limit the lignin’s large-scale use in biorefineries. Recent studies show that kraft lignin can be used as lignosulfonates and dispersants, technical carbons, transportation fuels, bioplastics, and adhesives, but some technological hurdles must be overcome and several industrial tests must be developed to make these uses viable.
Preparation of high conductivity hierarchical porous carbon based on sodium lignosulfonate with pre-crosslinking
Authors: Yi Yanjie , Hou Yi , Li Youming
Published: February 2021

The electrode material plays a key role in the performance of a supercapacitor. This study reports a method to prepare high conductivity hierarchical porous carbon with pre-crosslinking based on sodium lignosulfonate, which usually is burned as a waste effluent in pulp and paper mills. Results indicate pre-crosslinking with glutaraldehyde and ethyleneimine polymer, activation with less potassium hydroxide KOH, and finally carbonization to form carbon materials of hyperbranched macromolecules with ultra-rich specific surface area of 2780 m2/g and reasonable pore size distribution. The prepared carbon material showed high specific capacitance and good electrochemical performance when used as electrode materials for supercapacitors. At 0.5 A/g, the specific capacitance was 305 F/g, and the specific capacitance decay was only 6.2%, even after 2500 consecutive charge/discharge cycles, which revealed the huge potential for the supercapacitor characteristics with long service life. The results provided a high-valued application of industrial waste, which is important to further the sustainable development of the national economy.
Validation of The Reading House and Association With Cortical Thickness
Authors: Hutton John S. , Dudley Jonathan , Huang Guixia , Horowitz-Kraus Tzipi , DeWitt Thomas , Ittenbach Richard F. , Holland Scott K.
Published: February 2021

BACKGROUND AND OBJECTIVES:

The American Academy of Pediatrics recommends literacy and school readiness promotion during well visits. The Reading House (TRH) is a children’s book–based screener of emergent literacy skills in preschool-aged children. Vocabulary, rhyming, and rapid naming are core emergent skills, and reading abilities are associated with thicker cortex in the left hemisphere. Our objective was to expand validity of TRH relative to these skills and explore association with cortical thickness.

METHODS:

Healthy preschool-aged children completed MRI including a T1-weighted anatomic scan. Before MRI, TRH and assessments of rapid naming (Comprehensive Test of Phonological Processing, Second Edition), rhyming (Pre-Reading Inventory of Phonological Awareness), vocabulary (Expressive Vocabulary Test, Second Edition), and emergent literacy (Get Ready to Read!) were administered. Analyses included Spearman-ρ correlations (rρ)accounting for age, sex, and socioeconomic status (SES). MRI analyses involved whole-brain measures of cortical thickness relative to TRH scores, accounting for covariates.

RESULTS:

Seventy children completed assessments (36–63 months old; 36 female) and 52 completed MRI (37–63 months; 29 female). TRH scores were positively correlated with Comprehensive Test of Phonological Processing, Second Edition (rρ = 0.61), Expressive Vocabulary Test, Second Edition (rρ = 0.54), Get Ready to Read! (rρ = 0.87), and Pre-Reading Inventory of Phonological Awareness scores (rρ = 0.64; all P < .001). These correlations remained statistically significant across age, sex, and SES groups. TRH scores were correlated with greater thickness in left-sided language and visual cortex (P–family-wise error <.05), which were similar for higher SES yet more bilateral and frontal for low SES, reflecting a less mature pattern (P–family-wise error <.10).

CONCLUSIONS:

These findings expand validation evidence for TRH as a screening tool for preschool-aged children, including associations with emergent skills and cortical thickness, and suggest important differences related to SES.
Demanda laboral de profesionales graduados en Gestión Cultural en Costa Rica, una aproximación cuantitativa
Authors: Alpízar Valverde Nicolás
Published: February 2021

En Costa Rica existe una efervescente actividad cultural, lo cual supone la necesidad de profesionales especializados en su gestión. En esta investigación, se estimó la demanda costarricense de profesionales en Gestión Cultural para 2014, como parte de un estudio de viabilidad para crear una carrera especializada, en el seno de la Universidad de Costa Rica. Dada la escasez nacional de datos primarios y metodologías para la cuantificación, se propuso un modelo propio, con apoyo cualitativo, cuyo alcance fue exploratorio y descriptivo. Para lograrlo, se trazaron relaciones entre perfiles profesionales (creados por autores nacionales) y organizaciones que implementaban prácticas de gestión cultural. Mediante cuatro niveles de categorización, se determinó el número ideal de profesionales requeridos, cifra que fue ponderada mediante porcentajes que expresan el mínimo necesario para atender las necesidades de gestión en cada organización. Se generó un modelo matemático que facilita la posterior argumentación. Los resultados son presentados mediante tablas y prosa. La evaluación fue realizada mediante un análisis incremental por escenarios. Al final se incluyen algunas reflexiones sobre la configuración encontrada y los aportes metodológicos.

Museo de la Dignidad: entre la polémica y la memoria. Una mirada sobre las acciones artístico-políticas en el octubre chileno de 2019
Authors: Ribeiro Cavalcanti Raíza , Barbosa de Oliveira Teresa Maria
Published: February 2021

La revuelta social del 18 de octubre, en Chile, constituyó un proceso que estremeció al país desde sus bases más profundas. Ese momento de explosión social estuvo acompañado de una igual explosión en la producción de imágenes, performances y acciones artísticas, por todo el país, que evidenciaron la profunda dimensión simbólica de las manifestaciones. En ese contexto, llama la atención la acción Museo de la Dignidad, creada por un colectivo homónimo, que interviene en las imágenes producidas por las protestas, dispuestas en los muros de la ciudad de Santiago. Estas intervenciones insertan acciones callejeras en marcos dorados y suscitan una serie de cuestionamientos importantes sobre el arte y las instituciones de la cultura, patrimonio y preservación. Este artículo pretende analizar los distintos efectos de la acción Museo de la Dignidad en la esfera pública, a partir del método del Análisis de Discurso Crítico (Fairclough, 2001). Se enfatizará el aspecto de práctica discursiva crítica que interfiere en la esfera pública (tanto artística como socialmente), lo cual produce el disenso (Mouffe, 2014; Rancière, 2009) y baraja los regímenes del arte (Rancière, 2005) en su presencia.

Este artículo ensaya una aproximación a la crítica y a la resistencia que se desarrolla desde el campo de las artes visuales a la globalización neoliberal en la que se inserta Centroamérica desde hace algo más de tres décadas. Para ese fin, se realiza primero una caracterización de la inserción subalternizada de la región en la globalización neoliberal (la globananalización), con la cual se busca establecer sus vínculos estructurales y espectrales con el proceso de modernización periférica y la conformación de las mal llamadas banana republic. Con esa base histórica contextual, se analizan las modalidades de cuestionamiento y oposición al proceso de globananalización que, en los últimos unos años, viene realizando un trabajador del arte contemporáneo costarricense: Óscar Figueroa Chávez.
Pharmacological Management of Chronic Pain: How to Deal with the Catch-22 Situation
Authors: Andresen Trine , Niesters Marieke , Dahan Albert , Morlion Bart , O´Brien Tony , M. Drewes Asbjørn
Published: February 2021

Management of chronic pain is multidisciplinary, but pharmacotherapy is one of the mainstays of pain management. As applies in all medical therapies, clinicians must strive to achieve the best possible outcome for patients in terms of maximising benefit and minimizing risks, and ensure that this is conducted for each treatment and as an integral element in selecting appropriate therapies. If the balance between risk and benefits is not achieved and understood by the patient.

Chronic pain patients may already experience a degree of stigmatisation, which can be further exacerbated by evolving socio-political pressures in respect of analgesic availability and accessibility.  Hence, we have a Catch-22 situation in which patients become ensnared; they may need supervised access to legitimate analgesic medication(s) but these are not easily accessible because of concerns of the analgesic side-effects and abuse/misuse potential influencing both the individual and wider society.  

In this paper, we review the evidence in respect of analgesic use in chronic pain. We highlight the importance of: 1) better education and awareness of the problem, 2) evaluate the balance between effect and side effects rather than focusing on pain intensity alone, and include such composite measures in clinical trials, 3) identification of responders to treatment and systematic monitoring for misuse and 4) the use of big data to guide politicians away from inappropriate regulatory restrictions. Such a strategy will improve pain treatment and due to the major costs associated with chronic pain it will also be of benefit for society.

Face masks are the new normal and has become an essential part in our day to day lives for preventing the entry of virus to and from others during pandemic situation .The more common physical basis of entry of micro organisms are nose, eyes , mouth. Though eyes are protected using goggles, face masks shields against the contaminating substance. The efficiency of masks are dependent on the amount of contaminant removed by it, contributing to various factors such as the number of particles, mass , weight and so on. It is well know that wearing a surgical masks can help block the droplets from entering or spreading from the environment to the wearers respiratory tract and vice versa.There were high levels of  concerned raised anxiety on panic buying of face masks by the public  during the initial outbreak of the pandemic , a high shortage among the essential group of people in need of face masks by the health care teams as well as the common people to fight strong against the virus..According to aerosol science, whenever liquid hangs in air it is an aerosol, or a “droplet” to mean a coarse particle five micrometers or larger, and reserve “aerosol” for fine particles smaller than five micrometers in effective diameter. Many organizations are suggesting to make use of cloth masks instead of surgical ones in order to prevent the shortage of surgical masks on the Covid 19 health works and thus reducing the economic load on the same. Hence to have in a solution for the same have led to reusing of masks which are meant to be single use by process of efficient sterilization.

Deficiência adquirida por acidente de trabalho: a superação física, pessoal e profissional após uma amputação
Authors: Wellichan Danielle Da Silva Pinheiro , Santos Marcella Garcia Ferreira dos , Lino Carla Cristine Tescaro Santos
Published: February 2021

A deficiência adquirida pelo trabalhador, resultante de uma amputação, exige do indivíduo uma reconstrução física, emocional e profissional. Esse indivíduo, sendo contratado por empresas com registro em carteira de trabalho, pode ser amparado e orientado para volta à sua função pela previdência social brasileira.  Entretanto, o retorno ao mercado de trabalho consiste em um longo caminho a ser percorrido desde a sua reabilitação física e emocional, até a sua adaptação profissional. Diante desse percurso, há ainda o processo de inclusão pelo trabalhador, agora, pertencer à parcela da população vítima de desigualdades e preconceitos. Por se tratar de um assunto de relevância à comunidade, objetivou-se com esse trabalho, discutir, por meio da literatura nacional e internacional (bases de dados com artigos científicos, livros impressos e eletrônicos) subsídios teóricos que ilustram, desde o processo da amputação do trabalhador até as medidas e acompanhamentos necessários para a sua reabilitação e retorno ao mercado de trabalho. Embora exista a legislação que estabelece os direitos do trabalhador amputado ou com deficiência, encontramos estatísticas de exclusão, o que agrava a situação da reabilitação integral do indivíduo.

The purpose of this study is to extend the understanding of the business model of video game retailers using online and physical stores. It focuses on the impact of digitalization on the retailing industry considering different actors like retailers and consumers. This is a qualitative multiple-case study based on deductive reasoning. Two cases of click-and-mortar retailers operating in the Swedish video game industry have been considered along with feedback from customers. Online personal interviews and semi-structured interviews have been conducted with retailers and customers respectively. Both primary and secondary data have been used. Findings show that video game retailers need to encourage engagement through incentives and other activities to create value and change up their formats and sales strategies through pricing to reach new customers and focus on design of their online store fronts to convey trustworthiness. It offers some insightful practical suggestions to retailers who are struggling hard to adopt digital transformations in the industry. Authors’ proposed research model, based on Sorescu et al. (2011)’s retail business model and the empirical findings, contributes in the less explored domain of research on business models from retailer’s perspectives. Moreover, it adds values in industry specific study like the video game industry in Sweden considering all actors, which is argued as scarce.

Contemporary organizations frequently employ projects to leverage work across organizational units, utilizing specialized knowledge from different areas of the organization to meet specific quality criteria in a defined time period, at a set cost. Project managers act as hubs of knowledge in directing projects and driving their success, often using technology for this purpose. To date, little is known in how far technology support this knowledge sharing in the project management. The paper aims to explore project managers’ perceptions regarding their knowledge sharing and how this is supported by recent technology. The paper further explores benefits and challenges experienced by project managers when using the specific technology for their knowledge sharing. The research adopts the interpretive qualitative approach and collects data through semi-structured interviews with project managers using such a technology. 3 C’s analysis was used to analyze the collected empirical material to generate 6 concepts. The concepts are then reviewed in context of selected theoretical framework, including the informatics domain model by Beynon-Davies. The findings indicate that the technology largely supports knowledge sharing of project managers, both presenting opportunities for more efficiency as well as new challenges. The technology leads to change in the modus of knowledge sharing and also individuals’ approach: what, when and how knowledge is shared.This enhanced understanding contributes to existing theory and the insights can aid practitioners in development or introduction of technology in the workplace. The work also contributes to theory about how project managers can leverage knowledge across projects with the aid of such a technology as well as to project managers’ and managers’ work, such as to make efficient use of a technology and avoid certain challenges.
Omnichannel Retail and Business Model Transformation

Published: February 2021

Due to new technological developments and the ongoing digitalization, the traditional retail sector is currently exposed to major challenges. Digital Retail started with the development of e-commerce, when online companies, such as Amazon, began selling products online. These major online global players are still growing much faster than their smaller European retail competitors. As the absorption of buying power through online retailers, is dominated by global players based in Asia (Alibaba, Rakuten) and the United States (Amazon, eBay), Europe is experiencing a loss in revenue. In this highly competitive market, traditional European brick-and-mortar retailers face hard challenges. However, studies show that most customers currently do not prefer pure online retailers, but a hybrid model, since traditional stores provide them with the opportunity to experience products and to receive personal advice from experts. This paper is a contribution to on-going research on the business model transition to include digital channels in traditional retail companies and to integrate various channels that support and streamline personal customer requirements. Thus, the paper explores challenges and opportunities for omnichannel management in the digital retail industry.

ABSTRACT: Salmonellosis is a bacterial disease that affects several domestic animal species, and is commonly diagnosed in cattle, horses, and pigs. This study aimed to describe the epidemiological and pathological findings of eleven cases of enteric salmonellosis and two cases of salmonellosis with pulmonary involvement in cattle in Rio Grande do Sul State, Brazil. Clinical signs included fever, yellow diarrhea, sometimes with blood streaks, and dyspnea, with a clinical course ranging from 1 to 30 days. Eight cases occurred as outbreaks, whereas five cases occurred individually. Risk factors included inadequate handling practices, such as overcrowded facilities and comorbidities, including anaplasmosis. The main gross finding of the enteric presentation was fibrinonecrotic enterocolitis, occasionally associated with button ulcers, mesenteric lymphadenomegaly, splenomegaly, cholecystitis and hepatomegaly. In addition, one steer with a chronic clinical progression presented severe segmental thickening of the ileum, associated with intestinal rupture and peritonitis. In the respiratory system, the main findings were reddened, non-collapsed lungs, with multifocal areas of atelectasis. The main microscopic findings were observed in the small and large intestines, and these were characterized by severe necrosis and mucosal ulceration, associated with marked inflammatory infiltrate of neutrophils and fibrin deposition intermixed by rod-shaped bacterial aggregates, and fibrosis, as well as interstitial pneumonia. Seven cases yielded positive bacterial cultures for Salmonella spp. and three serovars, namely Typhimurium, Dublin, and Panama were identified. All cases exhibited immunolabeling for Salmonella spp. using immunohistochemistry.
Transmission systems in agricultural tractors marketed in Brazil

ABSTRACT: In a tractor, the transmission system transmits the power generated in the engine to the driving wheels, hydraulic systems, and power take-off (PTO). There are several types of transmission systems available in the Brazilian market ranging from the simplest to the most advanced. Therefore, the objective of this study was to verify the different types of transmission systems present in 228 models of agricultural tractors produced and marketed in Brazil during 2019. The tractor models were grouped based on the engine power and the transmission systems were classified as sliding, partially synchronized, synchronized, semi powershift, full powershift, and continuously variable transmission (CVT). According to this classification, it was found that most tractors belonged to Class III (51.5-73.5 kW) with 66 models in total. However, even with continuous modernization in this field and with tractors becoming increasingly independent from the operator, 66% of transmission systems are still mechanical. However, CVT systems, which are available only in tractors with an engine power above 117.7 kW, are expected to be equipped on less powerful tractors in the coming decades.

Abstract: Eunotia species from a stream located in the surrounding area of the Iguaçu National Park conservation unit were analyzed. Samples were monthly collected from September 2012 to August 2013. The periphytic material, manually obtained by squeezing aquatic macrophytes, was oxidized and analyzed under light and scanning electron microscopy. Twenty-one infrageneric taxa of Eunotia were identified, measured, and illustrated. Eunotia caniculoides sp. nov. is proposed as a new species, and eight taxa are new records for Paraná state.
Sobre a Dedução do Axioma de Carathéodory da Segunda Lei da Termodinâmica dos Princípios de Clausius e Kelvin
Authors: da Silva Júnior Pedro F.
Published: February 2021

O formalismo de Carathéodory para a termodinâmica clássica é uma rica abordagem alternativa para essa teoria, apesar de impopular entre estudantes e professores de física. Essa abordagem dispensa o conteúdo das máquinas térmicas para a apresentação da segunda lei da termodinâmica. Neste artigo, discutimos o formalismo de Carathéodory historicamente, e mostramos como o axioma de Carathéodory da segunda lei da termodinâmica se deduz, didaticamente, do princípio de Clausius e do princípio de Kelvin. Além disso, fornecendo também um caráter objetivo para este artigo, no sentido de buscar popularizar o ensino do formalismo de Carathéodory em disciplinas de termodinâmica clássica em nível de graduação, guiamos o leitor até a obtenção da entropia e do conteúdo matemático da segunda lei da termodinâmica através desse formalismo. Por último, considerando a ampla literatura revisada, a prova que demos para a dedução do axioma de Carathéodory da segunda lei da termodinâmica a partir do princípio de Clausius é nova.
