Authors: Martins Vitor William Batista , Anholon Rosley , Sanchez-Rodrigues Vasco , Leal Filho Walter , Quelhas Osvaldo Luiz Gonçalves 
Published: July 2020

PurposeConfronting globalization, logistics systems need to achieve greater efficiency in processes to be competitive. Competitiveness is not related only to economic aspects; companies need to perform their activities aligned to the triple bottom line concept. In this context, the main objective of this research is to analyze how Brazilian professionals think about sustainable logistics through an exploratory study.Design/methodology/approachA set of 33 indicators, compiled from a literature review, was used to develop a research instrument applied in a survey of 50 professionals working with logistics processes in Brazilian companies. First, the Cronbach's alpha was run to verify the questionnaire reliability. Respondents were grouped through cluster hierarchical analysis, and their answers were analyzed through TOPSIS technique.FindingsThe results from the sample analysis showed that Brazilian professionals think in the three dimensions of TBL when considering sustainable logistics systems; however, social aspects are relegated to a second level of importance when compared with environmental and economic indicators. In addition, it is possible to highlight that most important environmental aspects are directly related to economic objectives.Originality/valueThere are few studies examining sustainable logistics system in Brazilian companies that consider the purpose mentioned by evidencing originality in the same way as this current study. The results presented here can contribute to amplifying debates in the theme.

Published: July 2020

PurposeThe gradual increase in geriatric issues and global imbalance of the ratio between patients and healthcare professionals have created a demand for intelligent systems with the least error-prone diagnosis results to be used by less medically trained persons and save clinical time. This paper aims at investigating the development of image-based colourimetric analysis. The purpose of recognising such tests is to support wider users to begin a colourimetric test to be used at homecare settings, telepathology and so on.Design/methodology/approachThe concept of an automatic colourimetric assay detection is delivered by utilising two cases. Training deep learning (DL) models on thousands of images of these tests using transfer learning, this paper (1) classifies the type of the assay and (2) classifies the colourimetric results.FindingsThis paper demonstrated that the assay type can be recognised using DL techniques with 100% accuracy within a fraction of a second. Some of the advantages of the pre-trained model over the calibration-based approach are robustness, readiness and suitability to deploy for similar applications within a shorter period of time.Originality/valueTo the best of the authors’ knowledge, this is the first attempt to provide colourimetric assay type classification (CATC) using DL. Humans are capable to learn thousands of visual classifications in their life. Object recognition may be a trivial task for humans, due to photometric and geometric variabilities along with the high degree of intra-class variabilities, it can be a challenging task for machines. However, transforming visual knowledge into machines, as proposed, can support non-experts to better manage their health and reduce some of the burdens on experts.

Authors: Zakery Amir , Saremi Mohammad Sadegh 
Published: July 2020

PurposeInternational businesses play a significant role in the growth, innovation and survival of technology-based firms (TBFs). Creating new opportunities in international markets, using communication networks and confronting constraints on available resources have distinguished the internationalization of small and medium-sized enterprises (SMEs) and intensified the importance of knowledge acquisition and continuous learning. This study aimed to (1) configure (the types and sources of) and (2) measure the internationalization knowledge of TBFs, by focusing on a knowledge-intensive part of the health industry in an emerging country: Iranian advanced medical equipment companies.Design/methodology/approachFor this purpose, a qualitative approach was adopted to interview the leaders of eight TBFs exporting medical equipment. Obtained data were investigated using content analysis.FindingsAccording to the content analysis results for configuration, technological knowledge and market knowledge were mainly obtained through direct experience and vicarious learning; however, internationalization knowledge is not so established as the third major knowledge area to integrate technological with market knowledge in line with corporate strategies of an internationalizing firm. For measurement of knowledge assets of internationalizing firms as a prerequisite for continuous improvement, several intellectual capital indices were extracted, including human, structural and relational capital.Originality/valueThis research complements existing literature in internationalization knowledge configuration via deploying an "Intellectual capital" perspective. It could enhance efforts for improving the learning of internationalizing SMEs, especially in the developing countries.

Indicators to measure the performance of sustainable urban entrepreneurship: an empirical case study applied to Portuguese cities and towns
Authors: Franco Mário , Rodrigues Margarida 
Published: July 2020

PurposeUrban sustainability is an inseparable dimension of today's cities; thus, the role played by creativity, and consequently sustainable urban entrepreneurship and the networks it raises, gives rise to the pro-activity of these two constructs toward a tripartition (economic, social and environmental). This study aims to measure sustainable urban entrepreneurship through a composite of existing indicators in the literature of cities.Design/methodology/approachIn this study, the authors followed a quantitative research by applying exploratory factor analysis. The sample contains 308 towns and cities in Portugal, and the data were collected using secondary databases (e.g. INE; PORDATA).FindingsThrough quantitative research, this study identified the key indicators that mediate sustainable urban entrepreneurship in cities, as a methodological tool for them to evaluate their sustainable entrepreneurial capacity.Practical implicationsThe results obtained here provide information to show that sustainable urban entrepreneurship is an essential construct for cities, allowing a solution to many of their urban problems by its association with creative economy and its influence on the revitalization of urban spaces by urban regeneration, and by the importance of networks in these, the latter being another fundamental construct.Originality/valueThis research makes important contributions to studies considering the sustainability construct in urban entrepreneurship area. It will help to fill part of the gap in existing studies involving the cities’ aspects in entrepreneurship field. Consequently, the main contribution of this study lies in identifying the indicators that contribute to cities' tripartite sustainable balance by assuming sustainable urban entrepreneurship as a crucial premise.
Functional diversity enhances tree growth and reduces herbivory damage in secondary broadleaf forests, but does not influence resilience to drought

Abstract

Since the mid‐20th Century, Europe has experienced an unprecedented forest expansion associated with the abandonment of rural landscapes. Secondary forests may provide relevant ecosystem services such as landscape defragmentation, biodiversity conservation, control of hydrological cycling and carbon sequestration.

Secondary forests may benefit from the legacies of the former agricultural land use, and exhibit enhanced growth. Moreover, they may differ from long‐established forests in terms of tree species composition and diversity, as community composition has been less modified by succession or management. However, we lack evidence whether the effects of land use legacies on tree species diversity may also result in differences in the response of secondary forests to biotic and abiotic disturbances.

We aimed to evaluate the effects of land use legacies on taxonomic and functional diversity and their effects on the response of temperate broadleaf forests to drought and herbivory damage. For this aim, we compared secondary beech Fagus sylvatica forests established after 1950 in abandoned pastures with long‐established (pre‐1950) forests. We calculated indices of taxonomic and functional diversity and determined mean growth and growth response of beech to two drought events (1991, 2006), and insect herbivory damage.

Secondary and long‐established beech forests marginally differed in species richness but the former exhibited a significantly higher Shannon diversity index and evenness. Yet, differences in taxonomic diversity did not result in differences in functional diversity between forest types.

Mean tree growth was higher in secondary than in long‐established forests and it increased with functional diversity in both forest types. However, diversity was unrelated with the growth response to drought. Insect herbivory damage decreased with increasing functional diversity but only in secondary forests.

Synthesis and applications. Promoting functional diversity in temperate broadleaf forests is a promising strategy for enhancing productivity (tree growth) while increasing the ability to cope with biotic disturbances (insect herbivory). This principle should be applied both in the management of long‐established as well as expanding secondary forests. Yet, functional diversity does not seem to ameliorate tree response to drought, highlighting the need for other silvicultural practices to address this environmental challenge.

AbstractBackgroundThis study aimed to analyze the genetics and treatments of the patients with the triad of diabetic ketoacidosis (DKA), hypertriglyceridemia, and acute pancreatitis (AP).MethodsWe conducted a retrospective study of six patients with the triad of AP, hypertriglyceridemia, and DKA at our hospital. All patients underwent plasmapheresis as part of their treatment. The clinical characteristics of the patients were obtained from the hospital information system and analyzed. Whole exome sequencing was performed using samples of one patient (case 6) and his family members.ResultsThe average triglyceride level before plasmapheresis was 3282.17 ± 2975.43 mg/dL (range: 1646‐9332 mg/dL). The triglyceride levels dropped by approximately 80% after plasmapheresis. None of the patients developed complications related from plasmapheresis. During follow‐up, patients 5 and 6 developed recurrent pancreatitis for several times and showed the formation of pancreatic pseudocysts. We identified three novel heterozygous missense mutations in the family of patient 6, including c.12614C > T (p.Pro4205Leu) in APOB, c.160G > C (p.Glu54Gln) in CILP2, and c.1199C > A (p.Ala400Glu) in PEPD.ConclusionsThree novel heterozygous missense mutations, including c.12614C > T (p.Pro4205Leu) in APOB, c.160G > C (p.Glu54Gln) in CILP2, and c.1199C > A (p.Ala400Glu) in PEPD were first identified in a patient with the triad of DKA, hypertriglyceridemia, and AP. The combination of plasmapheresis, hydration, and insulin therapy may have the greatest clinical benefits for these patients.
Sampling schemes and drift can bias admixture proportions inferred by structure
Authors: Toyama Ken S. , Crochet Pierre‐André , Leblois Raphaël 
Published: July 2020

AbstractThe interbreeding of individuals coming from genetically differentiated but incompletely isolated populations can lead to the formation of admixed populations, having important implications in ecology and evolution. In this simulation study, we evaluate how individual admixture proportions estimated by the software structure are quantitatively affected by different factors. Using various scenarios of admixture between two diverging populations, we found that unbalanced sampling from parental populations may seriously bias the inferred admixture proportions; moreover, proportionally large samples from the admixed population can also decrease the accuracy and precision of the inferences. As expected, weak differentiation between parental populations and drift after the admixture event strongly increase the biases caused by uneven sampling. We also show that admixture proportions are generally more biased when parental populations unequally contributed to the admixed population. Finally, with few exceptions, using a large number of markers reduces those biases, but using alternative priors for individual ancestry or the uncorrelated allele model only marginally affect the inference of admixture in most situations. We conclude that unbalanced sampling may cause important biases in the admixture proportions estimated by structure, especially when a small number of markers are used, and those biases can be worsened by the effect of drift and unequal genetic contribution of parental populations. Empirical studies should thus be careful with their sampling design and consider historical characteristics when using this software to estimate the ancestry of individuals from admixed populations.
Selective Deficits in Contingency‐Driven Ethanol Seeking Following Chronic Ethanol Exposure in Male Mice

Published: July 2020

BackgroundPeople with alcohol use disorders exhibit an overreliance on habitual response strategies which may result from a history of chronic alcohol exposure. Although habits are defined by behavior that persists despite changes in outcome value and in action–outcome relationships, most research investigating the effects of ethanol exposure on habits has focused only on outcome devaluation. A clear understanding of the effects of chronic alcohol exposure on the ability to flexibly update behavior may provide insight into the behavioral deficits that characterize alcohol use disorders.MethodsTo dissociate the effects of chronic intermittent ethanol (CIE) exposure on contingency‐mediated sucrose versus ethanol seeking, adult male C57Bl/6J mice were assigned to 2 separate experiments. In the first experiment, mice were trained to self‐administer ethanol prior to 2 cycles of interleaved CIE exposure by vapor inhalation. In a second experiment, mice were trained to self‐administer sucrose and ethanol in separate training sessions prior to 4 cycles of interleaved CIE. The use of contingencies to mediate reward seeking was assessed using a contingency degradation paradigm.ResultsIn mice trained to self‐administer only ethanol, 2 weeks of CIE resulted in escalated self‐administration. At this time point, CIE‐exposed mice, but not air‐exposed controls, exhibited ethanol seeking that was insensitive to changes in action–outcome contingency, consistent with habitual ethanol seeking. In mice trained to self‐administer ethanol and sucrose rewards in sequential sessions, no escalation in self‐administration across 4 weeks of CIE was observed. Under these conditions, neither Air‐ nor CIE‐exposed mice reduced ethanol seeking in response to contingency degradation. In contrast, sucrose seeking remained goal‐directed.ConclusionsOur results suggest that chronic ethanol exposure impairs contingency‐driven ethanol seeking more readily than sucrose‐seeking behavior. Further, these findings indicate that the transition from contingency‐mediated ethanol seeking occurs more rapidly than for sucrose seeking under similar ethanol exposure conditions.

Published: July 2020

AbstractBackgroundMagnetic resonance enterography (MRE) is the mainstay imaging modality in the evaluation of small bowel Crohn's disease (CD) activity and its associated complications. Few studies have assessed the indications for ordering it and its association with management changes. The objective was to identify the current clinical utilization of MRE and associated management changes in patients with established small bowel CD.MethodsA retrospective audit was conducted on all patients with established CD who underwent MRE at a tertiary centre from November 2014 to December 2017. Clinical indications, radiological findings and management changes were obtained from patient records.ResultsA total of 220 patients underwent a total of 287 MRE examinations. The most common indications for ordering MREs were based on patient symptoms (n = 204, 71.1%) and routine disease surveillance (n = 57, 19.9%). The most common radiological findings were inflammation (n = 156, 54.4%) and strictures (n = 98, 34.1%). Management changes post MRE occurred in 152 of 287 (53%) cases. Of the 152 patients, 87 (57.2%) had changes in medical management, 40 (26.3%) had surgical or endoscopic intervention and 25 (16.4%) had both medical and surgical management changes. Management changes following MRE in patients with new or concerning symptoms were significantly higher than in surveillance patients (OR 4.1, P = 0.000003).ConclusionThis study provides a foundation for understanding the current utilization of MRE in small bowel CD at a tertiary centre. However, its role in altering management particularly within surveillance patients is yet to be defined. Future prospective trials are required to better delineate its role and develop an algorithm for small bowel CD management.
Does well‐controlled overt hypothyroidism increase the risk of total knee arthroplasty?

Published: July 2020

AbstractBackgroundOvert hypothyroidism is widely accepted as a risk factor for adverse events following total knee arthroplasty (TKA). However, no prior study has preoperatively reversed hypothyroidism and reevaluated its risk. This retrospective study aimed at investigating whether well‐controlled overt hypothyroidism would still increase the risk of TKA.MethodsBetween November 2009 and November 2016, patients diagnosed with overt hypothyroidism but well controlled and underwent TKA were compared with euthyroid TKA patients. Data were extracted from our departmental database. Chi‐squared test and t‐tests were used for comparisons.ResultsHypothyroid patients had more blood loss and lower postoperative haemoglobin (Hb) and haematocrit level than the control group (all P < 0.05). Although the postoperative anaemia rate was lower in the control group (P = 0.01), there was no significant difference in the transfusion rate between the two groups (2.99% versus 7.46%, P = 0.10) or in the rates of other complications (P > 0.05). Interestingly, intramuscular venous thrombosis rate in hypothyroid patients was significantly lower than that in the control group (1.49% versus 9.70%, P = 0.00). Clinical outcome scores were comparable between the two groups throughout the course. And only one case of infection occurred in the hypothyroid patients.ConclusionWell‐controlled overt hypothyroidism did not increase the risk of TKA, except for perioperative blood loss. Surgeons should be aware that even if hypothyroidism is reversed, the risk of more perioperative blood loss still exists and that, consequently, perioperative blood management is still essential in this population.
What constitutes fair shared decision‐making in global health research collaborations?
Authors: Pratt Bridget 
Published: July 2020

AbstractFunders (located primarily in high‐income countries) and high‐income country researchers have historically dominated decision‐making within global health research collaborations: from setting agendas and research design to determining how data are collected and analysed and what happens with findings and outputs. The ethical principle of shared decision‐making has been proposed as a way to help address these imbalances within collaborations and to reduce semicolonial and exploitative forms of global health research. It is important to be clear about what shared decision‐making means in order to ensure that it is not done in a tokenistic, shallow way. Thus far, the principle’s content has not been examined and articulated in detail. This paper aims to start the process of delineating a concept of fair shared decision‐making as a minimum standard for global health research. Using two hypothetical case examples, the paper will demonstrate that global health research practice is often inconsistent with ideal shared decision‐making. In such instances, it can be difficult to decide whether shared decision‐making within collaborations is fair. The paper describes how the two cases do not meet criteria for unfair or non‐ideal shared decision‐making, despite having potentially morally troubling features. The nuances of these examples of research practice help to generate clearer ideas about how to judge fairness in shared decision‐making. The paper concludes by presenting ideas about when soft power can be fairly employed between high‐income‐country and low‐ and middle‐income‐country partners and what fair compromise agreements may look like in shared decision‐making.
