PROPOSAL FOR AN ANALYSIS MODEL FOR IDENTIFYING SUSTAINABILITY PRACTICES THAT ARE ABLE TO INCREASE THE VALUE IN SUPPLY CHAINS

This research analyses sustainability practices involving the economic, environmental and social pillars, on two supply chains of perfumes and moisturizers. A literature review was carried out on topics supply chain, supply chain management, sustainable supply chain management and the indicators proposed by Global Reporting Initiatives. The research adopted a multiple case study methodology, with qualitative approach and exploratory nature, and interviews were used as data collection technique. The units of analysis were two supply chains of the personal hygiene sector, perfumes and cosmetics, and the focal company and upstream companies were analyzed. There was a difference in the implementation of practices between supply chains even considering the same focal company. There is disagreement between what the focal company and the suppliers understand as a requirement. As practical contribution, sustainability practices along productive chains are proposed, in order to help companies reach their economic, social and environmental goals

A TAXA DE CÂMBIO E AS EXPORTAÇÕES DO ESTADO DO CEARÁ

A proposta deste artigo é analisar a relação entre as exportações do estado do Ceará e a flutuação cambial nos anos de 2019, 2020 e 2021, partindo-se do princípio de que a moeda nacional desvalorizada favorece as exportações; além de apresentar a evolução da exportação brasileira e do estado do Ceará no mesmo período, comparando as relações entre o volume exportado pelo Brasil, pelo estado do Ceará, e a flutuação cambial. O desenvolvimento deste trabalho baseou-se em investigações bibliográficas, bem como em diversas estatísticas publicadas por entidades nacionais e internacionais. Os dados foram tratados por análise de regressão linear simples e correlação bivariada. Nesse período de três anos, as exportações brasileiras e do estado do Ceará cresceram, respectivamente, 410% e 453%, enquanto o câmbio apresentou uma variação positiva de 51%, desvalorizando a moeda do País. A variação cambial explicou 12,7% da variação nos volumes exportados por uma empresa do estado do Ceará e 13% no caso das exportações brasileiras, apresentando uma baixa correlação entre essas variáveis, nos dois casos. Entretanto, não foi identificada correlação linear significativa entre as exportações realizadas pelo estado do Ceará e a flutuação cambial

Cubatao county (Brazil), stained territory: pollution and mass media

O nome “Cubatão” desperta no ouvinte, principalmente aqueles que já possuem mais de quatro décadas de idade, lembranças de reportagens divulgadas em período compreendido entre as décadas de l970 e 1980. Invariavelmente vem à memória termos que associavam a cidade à poluição ambiental, riscos de contaminação. O presente artigo pretende refletir sobre o estigma que paira sobre Cubatão, Estado de São Paulo, como o “Vale da Morte” a partir do trabalho de Lúcia da Costa Ferreira. Faz-se necessário examinar tal questão sob o enfoque dos meios de comunicação, os “mass media”, através dos quais houve a sedimentação da informação no imaginário popular, mesmo decorridas várias décadas. Isto permitirá entender alguns mecanismos na formação da memória coletiva cubatense que, em decorrência dos fatos apresenta características de baixa autoestima, o que repercute no próprio sentimento de pertencimento. Além disto, pretende realçar que a “memória coletiva” – construída através da mídia impressa, rádio e televisão – referenciou a cidade como território de poluição permanente e se apoia nos conceitos de Pierre Nora e Marshall McLuhan.The name “Cubatão” awakens in the listener, especially those who are already over four decades old, memories of reports published in a period between the 1970s and 1980s. Invariably, terms that associated the city with environmental pollution, contamination risks, come to mind. This article intends to reflect on the stigma that hangs over Cubatao city (state of Sao Paulo, Brazil), as the “Death Valley”, according to Lucia da Costa Ferreira’s research. It is necessary to examine this issue from the perspective of the ‘mass media’, through which there was the sedimentation of information in the popular imagination, even after several decades. This will allow us to understand some mechanisms of Cubatão’s collective memory which, because of facts, presents low self-esteem characteristics. All of this reflects on the feeling of belonging. In addition, the article intends to emphasize that the “collective memory” – constructed through the print media, radio, and television – referred to the city as a territory of permanent pollution and relies on Pierre Nora and Marshall McLuhan concepts

Polyhydroxyalkanoate Production from Eucalyptus Bark's Enzymatic Hydrolysate

ABSTRACT: In recent years, polyhydroxyalkanoates (PHAs) have gained notoriety because of their desirable properties that include proven biodegradability, biocompatibility, and thermal stability, which make them suitable alternatives to fossil-based polymers. However, the widespread use of PHAs is still challenging because of their production costs, which are greatly associated with the cultivation medium used for bacterial cultivation. In Portugal, one-quarter of the forest area is covered by Eucalyptus globulus wood, making its residues a cheap, abundant, and sustainable potential carbon source for biotechnological uses. In this work, eucalyptus bark was used as the sole feedstock for PHA production in a circular bioeconomic approach. Eucalyptus bark hydrolysate was obtained after enzymatic saccharification using Cellic (R) CTec3, resulting in a sugar-rich solution containing glucose and xylose. Although with differing performances, several bacteria were able to grow and produce PHA with distinct compositions, using the enzymatic hydrolysate as the sole carbon source. Pseudomonas citronellolis NRRL B-2504 achieved a high cellular growth rate in bioreactor assays (24.4 +/- 0.15 g/L) but presented a low accumulation of a medium-chain-length PHA (mcl-PHA) comprising the monomers hydroxydecanoate (HD, 65%), hydroxydodecanoate (HDd, 25%), and hydroxytetradecanoate (HTd, 14%). Burkholderia thailandensis E264, on the other hand, reached a lower cellular growth rate (8.87 +/- 0.34 g/L) but showed a higher biopolymer accumulation, with a polyhydroxybutyrate (PHB) content in the cells of 12.3 wt.%. The new isolate, Pseudomonas sp., revealed that under nitrogen availability, it was able to reach a higher accumulation of the homopolymer PHB (31 wt.%). These results, although preliminary, demonstrate the suitability of eucalyptus bark's enzymatic hydrolysate as a feedstock for PHA production, thus offering an exciting avenue for achieving sustainable and environmentally responsible plastic products from an undervalued forestry waste.info:eu-repo/semantics/publishedVersio

Concurrent Validity and Reliability of an Inertial Measurement Unit for the Assessment of Craniocervical Range of Motion in Subjects with Cerebral Palsy

Objective: This study aimed to determine the validity and reliability of Inertial Measurement Units (IMUs) for the assessment of craniocervical range of motion (ROM) in patients with cerebral palsy (CP). Methods: twenty-three subjects with CP and 23 controls, aged between 4 and 14 years, were evaluated on two occasions, separated by 3 to 5 days. An IMU and a Cervical Range of Motion device (CROM) were used to assess craniocervical ROM in the three spatial planes. Validity was assessed by comparing IMU and CROM data using the Pearson correlation coefficient, the paired t-test and Bland–Altman plots. Intra-day and inter-day relative reliability were determined using the Intraclass Correlation Coefficient (ICC). The Standard Error of Measurement (SEM) and the Minimum Detectable Change at a 90% confidence level (MDC90) were obtained for absolute reliability. Results: High correlations were detected between methods in both groups on the sagittal and frontal planes (r > 0.9), although this was reduced in the case of the transverse plane. Bland–Altman plots indicated bias below 5º, although for the range of cervical rotation in the CP group, this was 8.2º. The distance between the limits of agreement was over 23.5º in both groups, except for the range of flexion-extension in the control group. ICCs were higher than 0.8 for both comparisons and groups, except for inter-day comparisons of rotational range in the CP group. Absolute reliability showed high variability, with most SEM below 8.5º, although with worse inter-day results, mainly in CP subjects, with the MDC90 of rotational range achieving more than 20º. Conclusions: IMU application is highly correlated with CROM for the assessment of craniocervical movement in CP and healthy subjects; however, both methods are not interchangeable. The IMU error of measurement can be considered clinically acceptable; however, caution should be taken when this is used as a reference measure for interventions

Streptococcus pyogenes Meningitis in a Pediatric Patient: Case Report

Streptococcus pyogenes causes a wide spectrum of diseases in children. However, meningitis due to this pathogen is highly uncommon. Although rare, it is associated with a high case fatality rate and can result in severe neurological sequelae. We report a case of Streptococcus pyogenes meningitis in a previously healthy 3-year-old boy. The purpose of this case report is to emphasize that this agent should be considered a cause of meningitis in previously healthy infants because of its frequent association with complications, sequelae, and high mortality rates

Design, Validity, and Reliability of a New Test, Based on an Inertial Measurement Unit System, for Measuring Cervical Posture and Motor Control in Children with Cerebral Palsy

Objective: The aim of this study was to design and propose a new test based on inertial measurement unit (IMU) technology, for measuring cervical posture and motor control in children with cerebral palsy (CP) and to evaluate its validity and reliability. Methods: Twenty-four individuals with CP (4–14 years) and 24 gender- and age-matched controls were evaluated with a new test based on IMU technology to identify and measure any movement in the three spatial planes while the individual is seated watching a two-minute video. An ellipse was obtained encompassing 95% of the flexion/extension and rotation movements in the sagittal and transversal planes. The protocol was repeated on two occasions separated by 3 to 5 days. Construct and concurrent validity were assessed by determining the discriminant capacity of the new test and by identifying associations between functional measures and the new test outcomes. Relative reliability was determined using the intraclass correlation coefficient (ICC) for test–retest data. Absolute reliability was obtained by the standard error of measurement (SEM) and the Minimum Detectable Change at a 90% confidence level (MDC90). Results: The discriminant capacity of the area and both dimensions of the new test was high (Area Under the Curve ≈ 0.8), and consistent multiple regression models were identified to explain functional measures with new test results and sociodemographic data. A consistent trend of ICCs higher than 0.8 was identified for CP individuals. Finally, the SEM can be considered low in both groups, although the high variability among individuals determined some high MDC90 values, mainly in the CP group. Conclusions: The new test, based on IMU data, is valid and reliable for evaluating posture and motor control in children with CP

Evidências de Validade da Escala Conflito Trabalho-Família para Profissionais da Segurança Pública

The aim of this article is to present evidence of validity for the ‘work-family conflict scale’ with a sample of 10,383 professionals working in Brazilian public security. Cross-validation procedures were applied through the definition of two subsamples, exploratory and confirmatory factor analyses were performed. All ethical procedures were followed. The results found in both the exploratory factor analysis (‘Work Interference with Family’ Factor, with factor loadings between .91 and .81 and alpha of .93, and ‘Family Interference with Work’ Factor, with factor loadings between .96 and .71 and alpha of .90) and the confirmatory analysis (χ2/df <5; CFI >.98; TLI >.98; RMSEA <.10) demonstrate robust evidence of validity, indicating the use of the scale in other organizational contexts.O artigo tem como objetivo geral apresentar evidências de validade da escala ‘conflito trabalho-família’ junto a uma amostra de 10.383 profissionais que atuam na segurança pública brasileira. Optou-se pela condução dos procedimentos de validação cruzada, por meio da definição de duas subamostras, foram realizadas análises fatoriais exploratórias e confirmatórias.

Uso de AFLPS para discriminar raças primitivas de pupunha (Bactris gasipaes) na Amazônia brasileira

Although the first inhabitants of western Amazonia domesticated pejibaye (Bactris gasipaes Kunth, Palmae) or peach palm for its fruits, today it is widely planted for its heart-of-palm. Like other domesticates, pejibaye presents a complex hierarchy of landraces developed before the conquest of the Americas. The existence of three landraces (Pará, Solimões, Putumayo) was proposed along the Amazonas and Solimões Rivers, Brazil, based on morphological characteristics. There are some questions remaining about the intermediate landrace being an artifact of the morphometric analysis. AFLPs were used to evaluate the relationships among samples of these putative landraces. DNA was extracted from 99 plants representing 13 populations maintained in the Pejibaye Germplasm Bank, Manaus, AM; six primer combinations generated 245 markers via PCR, which were scored in an ABI Prism 310 sequencer and analyzed with GeneScan Software; Jaccard similarities were estimated and a dendrogram was generated with UPGMA. Two groups of plants were observed in the dendrogram instead of three, and were similar at 0.795. Each group contained two subgroups, similar at 0.815. One group (n=41) contained 73% Pará landrace plants, with one subgroup (n=22) containing 91% Pará, and the other (n=19) containing 53% Pará. The other group (n=58) contained 53% Solimões and 40% Putumayo landrace plants, with one subgroup (n=21) containing 52% Solimões and 43% Putumayo, and the other (n=35) containing 57% Solimões and 37% Putumayo. The first group confirmed the Pará landrace. The second group suggested that the Solimões landrace does not exist, but that the Putumayo landrace extends along the Solimões River to Central Amazonia.Os primeiros povos da Amazônia ocidental domesticaram a pupunha (Bactris gasipaes Kunth, Palmae) por seu fruto, embora hoje seja muito plantada por seu palmito. Como outros cultivos domesticados, a pupunha apresenta uma hierarquia complexa de raças primitivas criadas antes da conquista das Américas. A existência de três raças (Pará, Solimões, Putumayo) foi proposta ao longo dos rios Amazonas e Solimões, Brasil, com base em características morfológicas. Algumas dúvidas existem sobre a raça intermediária, pois podia ser um artefato da análise morfométrica. AFLPs foram usados para avaliar as relações entre amostras destas raças hipotéticas. DNA foi extraido de 99 plantas representando 13 populações mantidas no Banco de Germoplasma de Pupunha, Manaus, AM; seis combinações de 'primers' geraram 245 marcadores via PCR, que foram codificados num sequenciador ABI Prism 310 e analisados com o programa GeneScan; similaridades de Jaccard foram estimadas e um dendrograma foi criado com UPGMA. Dois grupos de plantas foram observados no dendrograma, em lugar de três, com similaridade de 0,795. Cada grupo continha dois subgrupos, similares a 0,815. Um grupo (n=41) continha 73% de plantas da raça Pará, com um subgrupo (n=22) contendo 91% Pará e o outro (n=19) contendo 53% Pará. O outro grupo (n=58) continha 53% de plantas da raça Solimões e 40% da Putumayo, com um subgrupo (n=21) contendo 52% Solimões e 43% Putumayo, e o outro (n=35) contendo 57% Solimões e 37% Putumayo. O primeiro grupo confirmou a raça Pará, mas o segundo grupo sugeriu que a raça Solimões não existe; em lugar desta raça, a raça Putumayo se extende ao longo do rio Solimões até a Amazônia Central

Relationship between leaf N concentrations and olive yields

Within an olive orchard there is a huge productivity difference among individual trees. Also the alternate bearing pattern of this species is well documented. These aspects, as well as other like pruning, make difficult the interpretation of plant analysis results. In Ibis work, we made a simple exercise based upon the results from 48 individual-trees for two consecutive years. Groups of 12 similar young trees were submitted to four different soil management systems, influencing e nutritional status and productivity
