Efeito do sítio de venopunção nos parâmetros hematológicos em tigre-d'água-americano, Trachemys scripta elegans Effect of the blood collection site on the hematological parameters in red-eared slider, Trachemys scripta elegans

O objetivo do presente estudo foi realizar a comparação entre dois sítios de coleta sanguínea em 24 exemplares de tigre-d'água-americano (Trachemys scripta elegans) oriundos de um criadouro comercial, localizado no município de Antonina, litoral do Paraná, Brasil. Os animais foram submetidos a contenção física e as venopunções foram realizadas no seio supraocciptal e na veia coccígea dorsal. As amostras heparinizadas foram identificadas e refrigeradas para posterior análise laboratorial. A contagem total de eritrócitos e leucócitos foi realizada pela técnica de hemocitometria. O hematócrito (Ht) e a hemoglobina (Hb) foram determinados pelo método de microhematócrito e cianometahemoglobina, respectivamente. A proteína plasmática total (PPT) foi determinada por refratometria e a contagem diferencial de leucócitos foi realizada através da técnica de Shilling. Houve diferença significativa no número de leucócitos e no valor da proteína plasmática total, e em ambos os casos os valores encontrados nas amostras provenientes da veia coccígea dorsal foram inferiores. A diferença encontrada no número de leucócitos provavelmente foi devido à contaminação por linfa, que também justifica o menor valor na concentração da proteína plasmática total. Conclui-se que é mais indicada a venopunção no seio supraocciptal quando comparado a veia coccígea dorsal.<br>The aim of the present study was to compare two different blood collection sites of 24 red-eared sliders (Trachemys scripta elegans) from a commercial breeder, situated in Antonina, Paraná, Brasil. The animals were physically restrained and paired blood samples were collected from the dorsal coccygeal vein and the occipital sinus. The samples were collected in syringes containing heparin. After collection the samples were identified and refrigerated to posterior hematological analysis. Red blood cell and white blood count were performed using a hemocytometer. The packed cell volume and hemoglobin were determined by the microhematocrit method and cyanmethemoglobin method, respectively. Total plasma protein was determined by refractometry and differential leukocyte count was performed by the Shilling technique. There was a significant difference in the total white blood cell count and on the total plasma protein value, and on both cases the results found on the samples from the dorsal coccygeal vein were lower. The difference found on the white blood cell count was probably due to the lymph contamination of the samples, which also justifies the lower values of total plasma protein. In conclusion, the occipital sinus is more recommended blood collection site than the dorsal coccygeal vein

Elevating the human experience (HX) through service research collaborations: introducing ServCollab

Purpose:Elevating the human experience (HX) through research collaborations is the purpose of this article. ServCollab facilitates and supports service research collaborations that seek to reduce human suffering and improve human wellbeing.Design/methodology/approach:To catalyze this initiative, we introduce ServCollab’s three human rights goals (serve, enable, and transform), standards of justice for serving humanity (distributive, procedural, and interactional justice), and research approaches for serving humanity (service design and community action research).Research implications:ServCollab seeks to advance the service research field via large-scale service research projects that pursue theory-building, research, and action. Service inclusion is the first focus of ServCollab and is illustrated through two projects (transformative refugee services and virtual assistants in social care). This paper seeks to encourage collaboration in more large-scale service research projects that elevate the Human Experience (HX).Practical implications:ServCollab seeks to raise the aspirations of service researchers, expand the skills of service research teams, and build mutually collaborative service research approaches that transform human lives.Originality/value:ServCollab is a unique organization within the burgeoning service research community. By collaborating with service researchers, with service research centers, with universities, with nonprofit agencies, and with foundations, ServCollab will build research capacity to address large-scale human service system problems. ServCollab takes a broad perspective for serving humanity by focusing on the human experience (HX). Current business research focuses on the interactive roles of customer experience and employee experience. From the perspective of HX, such role labels are insufficient concepts for the full spectrum of human life.</div

Service Engineering Models : History and Present-Day Requirements

Part 11: Collaborative TechnologyInternational audienceSince the field of service engineering emerged in the late 20th century, the service industry has undergone drastic changes. Among the reasons for these changes is the increasing digitalization, which has made it difficult for companies to successfully develop new service offerings. While numerous service engineering models are available to provide guidance during the design of new services, many of them cannot keep up with the requirements of today’s economic environment. The present paper examines the requirements that service engineering models need to meet in order to be suitable guidelines for the digital age. To this end, the introduction illustrates how digitalization has changed the service industry. Afterwards, selected service engineering models and related norms are presented. Finally, a set of requirements for modern service engineering models derived from best practices from recent years is introduced
