o Project Management Office (PMO) é estabelecido para melhorar a eficiência e eficácia das organizações ao ajudar os gerentes de projetos, as equipes de projetos, as áreas funcionais e os níveis ...organizacionais. De acordo com a percepção de desempenho do PMO, este artigo verifica as intensidades e influências dos fatores organizacionais: estratégia, sistemas de informação, gestão do portfólio de projetos, operações, redes de relacionamento, pessoas, gestão do conhecimento e cultura organizacional, quando comparados à ausência ou existência do PMO nas organizações. A análise de dados de 63 países foi realizada com a Partial Least Squares Structural Equation Modeling (PLS-SEM). Os resultados indicam que, para os respondentes que não atuam em um PMO, persiste um entendimento divergente do dos respondentes que exercem atividades em um PMO, em que a variância explicada no desempenho deste para as organizações que possuem um escritório de projetos corresponde a 43% no modelo da pesquisa.
The Project Management Office (PMO) is established to improve the efficiency and effectiveness of organizations by helping project managers, teams, functional areas, and organizational levels. Based on the perception of PMO performance, this paper verifies the influence of organizational factors such as strategy, information systems, project portfolio management, operations, relationship networks, people, knowledge management, and organizational culture, when comparing the attendance or non-attendance of PMO in organizations. Data analysis from sixty-three countries was carried out using Partial Least Squares Structural Equation Modeling (PLS-SEM). Results show a divergent understanding between respondents who perform activities under a PMO approach and those who do not, with a 43% variance in PMO performance for those organizations that count on a project office.

Le Bureau de gestion de projet ou Project Management Office (PMO) est créé pour améliorer l'efficacité et la rentabilité des organisations en aidant les gestionnaires de projet, les équipes de projet, les domaines fonctionnels et les niveaux organisationnels. Selon la perception de performance du pmo, l'article vérifie l'intensité et l'influence des facteurs organisationnels: la stratégie, les systèmes d'information, la gestion de portefeuille de projets, les opérations, les réseaux relationnels, les personnes, la gestion des connaissances et la culture de l'entreprise, par rapport à l’absence ou à l’existence de PMO dans les organisations. L'analyse des données de 63 pays a été réalisée à l'aide de la modélisation d'équation structurelle par la méthode des moindres carrés partiels. Les résultats montrent que, pour ceux qui ont répondu qu'ils n'agissaient pas dans un PMO, il persiste une compréhension divergente à celle de ceux qui exercent des activités dans un PMO. De même, la variance expliquée dans la performance du bureau de gestion de projet pour les organisations ayant un tel projet correspond à 43% dans le modèle de recherche.
Purpose – this paper aims to examine the factors that affect the acceptance and use of the Manufacturing Execution System from the point of view of end users, using the Unified Theory of Acceptance ...and Use of Technology (UTAUT) model.Theoretical framework - The technology acceptance model is based on principles adopted in the attitude paradigm of psychology, which specifies how to measure the relevant attitudinal components of behavior; distinguishes beliefs and attitudes and specific as external stimuli, the objective characteristics of an attitude object, are causally linked to beliefs, attitudes and behavior.Design/methodology/approach - Data were collected by the survey method, using the seven-point Likert scale. The approach was quantitative, using the Structural Equation Modeling technique, using SPSS V.25 software.Findings - The findings of this study showed that the Facilitating Conditions influence the Usage Behavior of users of the Manufacturing Execution System. The application of multi-group comparison analysis (MGA) showed that Effort Expectancy positively influences Behavioral Intention and Social Influence also positively affects Behavioral Intention.Research, Practical & Social implications - The study brings relevant contributions in relation to aspects of understanding about the level of acceptance of MES end users in the operation phase.Originality/value - This paper makes a contribution to the literature due to the pioneering nature of the research, since no research was found in academic bases that address the use of UTAUT with the MES system.

Purpose This research aims to identify the optimal configuration of investment which leads firms to their best competitive positions, considering the degree of concentration in the market. ...Design/methodology/approach The methodology was quantitative and based on secondary data with samples of 124, 106 and 90 firms from competitive environment classified as perfect competition, monopolistic competition and oligopoly, respectively. Proposed models' parameters were estimated by means of genetic algorithms. Findings Adjustments on firm's investment are contingent on the degree of competition they face. Results are in line with existing academic research affirmation that the purpose of investments is to create and exploit opportunities for positive economic rents and that investments allow firms to protect from rivals' competitive actions and reinforce the need for investment decision makers to consider the environment in which the firm is competing, when defining the amount of investment that must be done to achieve and maintain a favorable competitive advantage position. Originality/value This research brings two main original contributions. The first one is the identification of the optimal amount of capital and R&D investments which leads firms to their best competitive positions, contingent to the degree of concentration of the competitive environment in which they operate, and the size of the firm. The second one is related to the use of genetic algorithms to estimate optimization models that considers the three competitive environments studied (perfect competition, monopolistic competition and oligopoly) and the investment variables in the linear and quadratic forms.

Desde o menor número de casos reportados em 2000, os casos de sífilis aumentaram mundialmente, com maior incidência em homens que fazem sexo com homens e pacientes com HIV. O envolvimento ósseo é ...incomum na sífilis primária e secundária, com uma prevalência de 0,15 a 0,23%.
Paciente masculino, 36 anos, buscou pronto atendimento por cefaleia frontal, de moderada intensidade, com início há 3 meses e piora há três dias, após tratamento com penicilina G benzatina devido a sífilis diagnosticada em VDRL de rastreio. Dor era do tipo opressiva, acompanhada de edema na região frontal e na pálpebra superior direita, com sudorese noturna. Havia sido diagnosticado com HIV há 18 meses. Em uso de TARV. Última dosagem de carga viral há 11 meses, com resultado indetectável e CD4 de 184 células/mm3. Ao exame físico, bom estado geral, afebril, hemodinamicamente estável. Edema periorbitário à direita e em região frontal, sem sinais flogísticos. Exames laboratoriais demonstraram aumento da PCR e VHS. Foi realizada uma angiotomografia com sinais de osteomielite de calota craniana bilateral em região frontal, com maior comprometimento do lado direito. A lesão foi biopsiada. Na punção lombar, líquor sem aumento de celularidade e VDRL não reagente. Devido a suspeita de osteomielite por sífilis secundária, foi iniciado ceftriaxona 2g por dia, assim como sulfametoxazol trimetoprima profilático, pelo CD4 menor que 200. No quinto dia de internação, o paciente apresentou melhora significativa da cefaleia e edema. Paciente foi de alta hospitalar com ceftriaxona por 14 dias. Alguns dias após a alta, resultado do PCR de calota craniana para treponema foi positivo e confirmou o diagnóstico de osteomielite por sífilis secundária. Ao longo do monitoramento do tratamento, foram observadas quedas progressivas do VDRL. Após 22 meses, depois de um novo contato sexual, o paciente apresentou VDRL de 1:256, sendo diagnosticada reinfecção e realizada nova administração de penicilina G benzatina.
A presença de achados mucocutâneos e linfadenopatia levantam a suspeita de osteíte sifilítica, porém, no caso relatado, as únicas manifestações presentes eram cefaleia e edema. Não existe consenso sobre o tratamento dos casos de osteíte por sífilis secundária, uma vez que são raros. Os sintomas se resolvem após a terapia, mas as lesões ósseas podem persistir por até 7-11 meses.
The productivity of wood harvesting operations is one of the main viability indicators of the forestry enterprise, which is directly influenced by land, population, and operational planning ...characteristics. The variables that affect the productivity of harvesting machines are particularly difficult to measure and have complex relationships, making it challenging to predict the productivity of operations. This study generated a model using machine learning (ML) techniques to estimate harvesting productivity in Eucalyptus plantations in southeastern Brazil. The input variables for modelling harvesting productivity were the average individual tree volumes, wood volume in the stand, cutting age, spacing, operator experience, and the management regime. The database was randomly divided into training (70%) and validation (30%) datasets. Boosted, artificial neural network (ANN), and adaptive network-based fuzzy inference system (ANFIS) techniques were used to fit the model and were evaluated through statistics and graphical analysis of the residues. The configurations selected for training and validation to estimate harvester productivity resulted in correlation coefficient values greater than 0.9, and root-mean-square error (RMSE) percentages less than 12.41, indicating a strong correlation and high accuracy between the estimates and the observed values. The boosted technique yielded the best results, with correlation coefficients of 0.98 and 0.97, and RMSE percentages of 6.15 and 6.65 in training and validation, respectively. The worst performance for estimating harvesting productivity was obtained using the ANFIS technique. ML techniques were efficient in modelling the productivity of mechanised forest cutting with a harvesting model.
Resumo O ambiente no qual operam as organizações se mostra cada vez mais complexo e competitivo, por isso, as empresas têm sido levadas a se estruturar para dar respostas rápidas, flexíveis e ...inovadoras. Projetos são importantes instrumentos para promover mudanças e desenvolvimento. Desde a década de 1990 intensificou-se nas organizações a criação de Escritórios de Gerenciamento de Projetos que, aceitos pelo executivo, são o ponto central de apoio dentro da organização para que o trabalho orientado por projetos seja concluído dentro das restrições do negócio. As pesquisas internacionais apontam o Escritório de Gerenciamento de Projetos como foco de interesse, pois os resultados encontrados ainda não chegaram às respostas necessárias para ajudar os profissionais a resolverem seus problemas. Este artigo tem por propósito avaliar o desempenho do Escritório de Gerenciamento de Projetos a partir dos construtos: “estratégias de implantação”, ”capacitação e treinamento de pessoal” e “controle do ambiente de operações em projetos”. A abordagem foi a de pesquisa quantitativa em um estudo transversal único e o modelo conceitual foi examinado com a Modelagem de Equações Estruturais. Os resultados apontaram o grau de influência dos construtos no desempenho do Escritório de Gerenciamento de Projetos, sendo as pessoas o preditor mais significativo, seguido pelas estratégias e, finalmente, pelas operações.
Abstract The environment in which organizations operate is shown increasingly complex and competitive, leading companies to structure themselves in order to get quick, flexible and innovative responses. Projects are important instruments for promoting change and development. Since the 1990s, it’s been intensified in organizations the creation of the Projects Managements Offices, accepted by executive, which is the central point of support within the organization, so that work oriented by projects will be completed within the constraints of the business. The international research indicates the Project Management Office as a focus of interest, since the results found have not yet reached the answers needed to help professionals to solve their problems. This paper aims to evaluate the performance of the Project Management Office, from the constructs: “implementation strategies”, “capacitation and personnel training” and “control of the operations environment in projects”. The approach was a quantitative research in a single cross-sectional study and the conceptual model was examined with Structural Equation Modeling. The results indicate the degree of influence of constructs on Project Management Office performance, and people, is the most significant predictor, followed by strategies and finally operations.
Although forest fires are indispensable for some ecosystems, they can have profound economic, environmental, and social implications, especially when they reach high intensities. There are two ...crucial factors in fighting forest fires: the availability of water resources and the service network. The objective of this study was to propose an alternative methodology for allocating water reservoirs to fight forest fires. The research was divided into three stages: zoning of fire risk, delimitation of viable areas for the implementation of water reservoirs, and determining strategic locations for reservoir allocation. The variables analyzed were land use and occupation, provision of watercourses, relief orientation, slope, proximity to roads, temperature, and precipitation. Fuzzy logic, Euclidean distance, and network analysis were used as the modeling techniques. Scenarios with all risk classes and only the high- and very high-risk classes were analyzed. A total of 66% of the area was represented by the low- and moderate-risk fire classes and 53.16% had a low potential for reservoir allocation, influenced by the low availability of water resources in the area. The proposed model efficiently allocated the water collection points in the different scenarios, and allowed the determination of the areas most susceptible to the occurrence of forest fires and the optimal locations for the installation of reservoirs, with the allocation of 21 water reservoirs to attend the areas of high- and very high-risk of occurrence of fires at a safe speed (40 km h−1) and 47 reservoirs to meet all risk classes at the same speed. The proposed methodology is feasible, applicable, and adjustable and can be implemented in other conservation units and areas of economic interest.

PurposeThe main goal of this paper is to systematically evaluate the bibliographic production on neuromarketing from 1945 to 2018, with an emphasis on consumer behavior, to identify possible ...convergence of interests among health and marketing fields.Design/methodology/approachThis article was based on a systematic literature review (SLR) with the intention of investigating research related to neuromarketing by means of network analysis of citations.FindingsThe research reveals that there are formed networks in the health and management areas, but they are insufficient to enhance the neuromarketing results. Ethics has been mentioned in some studies, but the maps do not suggest that it is a developing field. Similar results can be seen within the sales area that can be capitalized on by research of gains related to consumer behavior.Research limitations/implicationsOne limitation of this study was the use of only one database (Web of Science®) that published several works from 1945 to the present time, but certainly has not exhausted the possibilities of research in the area.Originality/valueThis article helped to highlight the importance of ethics in clinical and business processes using neuroimaging, which could be an easy way to understand the behavioral and physiological mechanisms.
O objetivo deste artigo foi analisar de que maneira a marca de fraldas Pampers buscou construir sua personalidade no canal do Youtube. Para isto, utilizou-se uma pesquisa qualitativa exploratória, ...por meio de um Estudo de Caso (YIN, 2001) para analisar os cinco últimos vídeos postados no Youtube pela Pampers. Os resultados mostraram que a marca procurou agregar valor às fraldas fortalecendo sua imagem e explorando valores como amor, afeto, cuidado, carinho, conforto do bebê e segurança dos pais, buscando uma conexão, acima de tudo, emocional. Tal posicionamento caracteriza a Pampers como uma lovemark. O artigo procurou discutir aspectos relacionados à personalidade da marca, não sendo conclusivo e indicando a necessidade de pesquisas futuras para ampliar tal entendimento.
