ABSTRACT

We uncover fundamental dimensions of the process through which organizations embed the practice of fraternity through embarking on an organizational journey in the direction of the common good. Building on the latest encyclical of Pope Francis, Fratelli Tutti, about fraternal and social friendship, we offer insight into the understanding of what it means to become a fraternal organization and reflect on the key ethical and paradoxical challenges for organizations aiming at collectively contributing to the common good. We add to previous work by characterizing this journey as a process involving unique ethical challenges that emerge from the paradoxes associated with this process and how this might change the nature of the relationships between organizations and others within the organizational landscape.

ABSTRACT

Healthcare innovations emerge and develop in institutionally dense selective environments. New projects and propositions in healthcare sectoral ecosystems can be understood as product-service compacts, that is, complex solutions that dynamically integrate tangible and intangible elements in close interaction with users' needs and the evolving regulatory context under uncertainty and ambiguity. We advance the concept of "strategic encounters" to encapsulate, capitalise and extend the contribution by Palm and Fischier's on the key enabling managerial factors for healthcare innovation implementation under conditions of imperfect foresight. We intertwine creative assemblages that shape the formation of knowledge-intensive activities at the operators' level with scope of sectoral level interventions to underscore how the opportunities and constraints can enhance innovation for the common good. We use the case of digital data health regulatory agendas as illustration. We argue that this broader perspective on healthcare transformation is theoretically pertinent and practically useful, for management and policy.

ABSTRACT

Major technological advances that are being introduced in the global mining industry have an impact on work and employee attitudes toward safety. The objective of this study was to analyze the impact of empowerment and technology on safety behavior. The research design was cross-sectional, and the sample was composed of 403 employees in mining companies. To measure safety behavior we used Neal, Griffin and Hart scales, and psychological empowerment was measured using the Spreitzer scale. The results indicated high levels of empowerment on safety behavior and medium levels of technology's promotion and prevention factors in the employees surveyed. Also, the study revealed that the meaning dimension of empowerment and the promotion technology factor positively affect safety behavior. A further contribution of the study is in the design of a scale to measure the impact of technology on safety behavior, as there are no known scales for this.

ABSTRACT

As the work environment is increasing in competitiveness and stressfulness, more and more companies try to increase employee well-being. One option is allowing employees to bring their dogs to work, building on the considerable evidence that dogs have a positive influence on people's well-being. However, little is known about how a dog's presence influences the employees and the companies in offices. Therefore, we empirically scrutinize the presence of dogs in organizations and the impact of pet-friendly organizational policies, with multiple case studies with semi-structured interviews as their foundation. Based on an inductive approach for the data analysis, we found that organizational members consider that dogs can lower their stress, improve communication, and foster social cohesion when a flexible organizational culture is in place. This includes the following: Problems in the company are openly addressed; employees have job autonomy, with flexibility to take breaks; and mistakes and errors are allowed to be made by employees and their companions alike, and room to find solutions is given. The inflexible permission of pets at work can, on the contrary, create pressure and stress in employees. For the business world, this implicates that this kind of incentive only leads to success if the right framework and culture is in place, and it cannot only be seen as an instrument to increase employee well-being.

ABSTRACT

The spread of the COVID-19 pandemic in Italy has had disastrous effects on the national economy. The hospitality sector has experienced a significant impact from the crisis: starting from March 2020 it has literally collapsed. Experts believe it will take three years for the sector to recover. Confronted with a dramatic uncertainty, which imposed rapid action, hospitality leaders need to nurture resilience. To enrich current understanding of the way resilient leadership unfolds to respond to jolts, we draw on an exploratory qualitative research involving Italian hotel managers. Following in-depth interviews, we show that resilient leadership and improvisation are deeply interconnected. Their interdependence entails two practices, namely gardening and learning. This suggests a paradoxical tension: to exercise resilience, leaders need to be at the same time in the system, by actively learning from events, and outside the system, by zooming out as they focus on ongoing planning for the next move.

ABSTRACT

Long-term stewardship is usually represented as a stable structural condition and portrayed as a source of competitive advantage to firms (including family businesses) that use it as a mode of governance. Less is known about how organizations engage with stewardship as a process. We embrace a process approach to report a case study about the unfolding of stewardship in a multi-business family group. We conclude that stewardship is a process marked by critical tensions and paradoxes; by exploring the nature of these we uncover further dimensions and responses to the paradoxes of stewardship.

ABSTRACT

Although the first coronavirus disease 2019 (COVID-19) wave has peaked with the second wave underway, the world is still struggling to manage potential systemic risks and unpredictability of the pandemic. A particular challenge is the "superspreading" of the virus, which starts abruptly, is difficult to predict, and can quickly escalate into medical and socio-economic emergencies that contribute to long-lasting crises challenging our current ways of life. In these uncertain times, organizations and societies worldwide are faced with the need to develop appropriate strategies and intervention portfolios that require fast understanding of the complex interdependencies in our world and rapid, flexible action to contain the spread of the virus as quickly as possible, thus preventing further disastrous consequences of the pandemic. We integrate perspectives from systems sciences, epidemiology, biology, social networks, and organizational research in the context of the superspreading phenomenon to understand the complex system of COVID-19 pandemic and develop suggestions for interventions aimed at rapid responses.

ABSTRACT

INTRODUCTION: Low-molecular-weight heparin (LMWH) is the standard treatment for cancer-associated venous thromboembolism (VTE). There have been no specific studies evaluating bemiparin for VTE in people with cancer. The aim of this study is to evaluate the effects of bemiparin for long-term treatment of VTE in routine clinical practice. METHODS/PATIENTS: Prospective observational study. Consecutive patients with active cancer and VTE, under treatment with bemiparin for at least 6 months, were recruited. RESULTS: We included 89 patients. The 6- and 9-month cumulative VTE recurrence rates were 2.4% and 5.9%, respectively. The 6-month cumulative rate of major bleeding was 1.3%, and of clinically relevant non-major bleeding, 8%. CONCLUSIONS: The incidence of events in this study is lower than that reported in randomized trials. Bemiparin is effective and safe for the long-term treatment of cancer-associated VTE in routine clinical practice.

ABSTRACT

Purpose: After surgical resection, an ample prognosis variability among stages is observed. Multiple prognostic factors are individually studied and some CRC classifiers have been proposed. Not one have been implemented into clinical practice. Methods/patients: We classified 105 patients with resected CRC (stage I-III) into five molecular subtypes using BRAFV600E and RAS (KRAS; NRAS) status, and the expression of DNA mismatch repair (MMR) proteins (MLH1 and MSH2). Clinicopathological features and DFS) of distincts groups were evaluated. Results and conclusions: RAS and BRAFV600E mutations were detected in 43.8 and 11.4% of patients, respectively. 19% of tumours had lack of expression of any MMR proteins reflecting a system deficiency (dMMR). Patients with any RAS mutation had lower DFS that patients with RAS wild type (wt) (40.23 vs 45.26 months; p value = 0.035). Of a total of five molecular subtypes, three were MMR proficient (pMMR): RAS mutated (39%), BRAFV600E mutated (6.7%) and RAS/BRAFV600E wt (35.2%); and two were dMMR: BRAFV600E mutated (4.8%) and BRAFV600E wt (14.3%). Left side tumours were more frequently observed in pMMR/RAS and BRAFV600E wt subtype, and right side tumours in dMMR subtypes. Among the three pMMR subtypes, a benefit survival was observed for patients without any mutation in BRAFv600E or RAS oncogenes (median of DFS = 45.5 vs 40.98 months in RAS mutated group; p = 0.084 and vs 34.13 in BRAFv600E mutated group; p = 0.031). Molecular classification using these biomarkers can be useful to identify groups with differences in prognosis

ABSTRACT

The Psychological Capital Questionnaire (PCQ) is the most commonly used measure for assessing psychological capital in work settings. Although several studies confirmed its factorial validity, most validation studies only examined the four-factor structure preconized by Luthans, Youssef, and Avolio, not attending to empirical evidence on alternative factorial structures. The present study aimed to test the psychometric properties of the Portuguese version of the PCQ, by using two independent samples (NS1 = 542; NS2 = 115) of Portuguese employees. We conducted a series of confirmatory factor analyses and found that, unlike previous findings, a five-factor solution of the PCQ best fitted the data. The evidence obtained also supported the existence of a second-order factor, psychological capital. The coefficients of internal consistency, as measured by Cronbach's alpha, were adequate and test-retest reliability suggested that the PCQ presented a lower stability than personality factors. Convergent validity, assessed with average variance extracted, revealed problems in the optimism subscale. The discriminant validity of the PCQ was confirmed by its correlations with Positive and Negative Affect and Big Five personality factors. Hierarchical regression analyses showed that this measure has incremental validity over personality and affect when predicting job performance.

ABSTRACT

AIMS: The aim of this work was to evaluate the efficacy and safety of Lippia origanoides essential oil as a preservative in industrial products. METHODS AND RESULTS: The composition, antimicrobial activity, mutagenic and toxic potential of L. origanoides were determined. Then, the effect of essential oil as a preservative in food, cosmetics and pharmaceutical products was evaluated. The essential oil of L. origanoides consisted mainly of oxygenated monoterpenes (38·13%); 26·28% corresponded to the compound carvacrol. At concentrations ranging from 0·312 to 1·25 µl ml-1 and in association with polysorbate 80, the essential oil of L. origanoides inhibited the growth of all the tested micro-organisms. The medium lethal dose in mice was 3·5 g kg-1 , which categorizes it as nontoxic according to the European Union criteria, and negative results in the Ames test indicated that this oil was not mutagenic. In combination with polysorbate 80, the essential oil exerted preservative action on orange juice, cosmetic and pharmaceutical compositions, especially in the case of aqueous-based products. CONCLUSIONS: Lippia origanoides essential oil is an effective and safe preservative for orange juice, pharmaceutical and cosmetic products. SIGNIFICANCE AND IMPACT OF THE STUDY: This study allowed for the complete understanding of the antimicrobial action and toxicological potential of L. origanoides essential oil. These results facilitate the development of a preservative system based on L. origanoides essential oil.

ABSTRACT

Sirtuins (Sirt) are NAD-dependent deacetylases that are activated by the antioxidants resveratrol (RSV) and lipoic acid (LA). The objective of this study was to determine in bovine liver and muscle slice cultures the effect of RSV and LA treatment on the expresssion of Sirt1, Sirt3, peroxisome proliferator-activated receptor γ coactivator 1α (PPARGC1A), and the forkhead box O transcription factors FoxO1 and FoxO3 as well as other factors involved in glucose and lipid metabolism and related to Sirt activity. Tissue slices from crossbred bulls were treated during 60 min with 40 or 80 µ RSV and 30, 100, 300, or 1,000 µ LA under restricted conditions (Krebs-Ringer buffer without nutrients) and fed conditions (2.5 m propionate in combination with 1 n glucagon) for liver slices or with 0.01 µ epinephrine for muscle slices. Quantitative real-time PCR was used to analyze the expression of the mRNA for the genes studied and western blot analysis for the expression of the protein for Sirt1. Our results show that the expression of the mRNA for Sirt1 was enhanced by RSV in liver under restriction ( ≤ 0.0112) and by LA in muscle, more under restriction ( ≤ 0.0121) than after epinephrine administration ( < 0.0001). Sirt3 is affected in a dose-dependent manner by both compounds in both tissues and under both metabolic conditions ( ≤ 0.0452). The expression of the protein for Sirt1 was increased by LA in both tissues under restricted conditions ( = 0.0026 and = 0.0201, respectively) but in liver also in fed conditions ( = 0.0016). Genes involved in the antioxidant response were upregulated in both tissues. These results indicate that bovine Sirt respond differently to RSV and LA stimulation than monogastric Sirt do and that gluconeogenesis in ruminants is not related to Sirt to the same degree as in monogastric species. However, these results provide information about the possible role of Sirt in ruminant metabolism.

ABSTRACT

BACKGROUND: chronic diseases are responsible for 60% of deaths and 75% of spending on public health. There are few works on the prevalence of this type of pathology in prison. OBJECTIVE: Describe the prevalence of chronic major diseases in the population and the major risk factors observed. METHODS: Multicenter transversal descriptive study. The sample size was 1,170 people, who were selected through sampling stratified with simple allocation by strata among 9 prisons in the country. There were interviews and physical examinations between May and June 2013. Variables were collected: socio-demographic, diagnostic, anthropometric, clinical-analytical and risk factors. A descriptive and subsequent comparative analysis was carried out using non-parametric tests for quantitative variables using the Mann-Whitney test and a Ji-square test for categorical variables. Subsequently, binary logistic regression models to evaluate the influence of factors of risk in major pathologies. The manuscript was approved by the Ethics Committee for clinical research of the University General Hospital of Castellon. RESULTS: 1 of every 2 inmates has some type of chronic disease out of the 1,077 participated (92.1). Median age of 37.4 years IQR (30.0 to 44.8). 95 males, 40.6 foreigners. Prevalence: dyslipidemias (34.8); arterial hypertension (17.8); Diabetes (5.3); asthma (4.6); COPD (2.2); ischaemic heart disease (1.8) and (1.5) cardio-circulatory pathologies. Main risk factors: smoking, obesity, abdominal fat distribution, consumption of cocaine and age. CONCLUSIONS: It would be interesting to establish early diagnosis, encourage giving up smoking, and physical activity and dietary advice to combat the major modifiable risk factors.

ABSTRACT

Sirtuins are NAD(+)-dependent histone and protein deacetylases, which have been studied during the last decade with a focus on their role in lifespan extension and age-related diseases under normal and calorie-restricted or pathological conditions. However, sirtuins also have the ability to regulate energy homeostasis as they can sense the metabolic state of the cell through the NAD(+)/NADH ratio; hence, changes in the diet can modify the expression of these enzymes. Dietary manipulations are a common practice currently being used in livestock production with favorable results, probably due in part to the enhanced activity of sirtuins. Nevertheless, sirtuin expression in livestock species has not been a research target. For these reasons, the goal of this review is to awaken interest in these enzymes for future detailed characterization in livestock species by presenting a general introduction to what sirtuins are, how they work and what is known about their role in livestock.

ABSTRACT

A low glycemic diet may improve metabolic control in type 2 diabetes, but the debate continues. Fruits, despite the fructose they contain, may also lower the glycemic index, as well as its consumption has been associated with a reduction in A1c levels and can positively influence HDL cholesterol, blood pressure and risk of coronary heart disease in general. There is no relationship between fat intake and A1c. On the consumption of alcohol has been reported that moderate alcohol consumption is associated with a lower prevalence of metabolic syndrome, although there is information that relates to the A1c. This article reviews the published evidence on the effect of consumption of fruits, fats and alcohol on metabolic control in diabetics.

ABSTRACT

Una dieta con bajo índice glicémico puede mejorar el control metabólico en la diabetes tipo 2, pero el debate aún continúa. Las frutas a pesar de la fructosa que contienen, también puede bajar el índice glicérico, además su consumo se ha asociado con una reducción de los niveles de A1c y pueden influir positivamente en el colesterol HDL, presión arterial y riesgo de enfermedad coronaria en general. Con respecto a la ingesta de grasa no se observa una relación entre ella y la A1c. Con respecto al consumo de alcohol se ha reportado que el consumo moderado de alcohol se asocia con una menor prevalencia de síndrome metabólico, aunque no hay información que lo relacione con el A1c. En este artículo se revisa la evidencia publicada sobre el efecto del consumo de frutas, grasas y alcohol sobre el control metabólico en diabéticos (AU)

ABSTRACT

Mostramos como as forças do carácter e as virtudes ajudam os líderes globais a ser mais eficazes e a contribuir para o desempenho positivo das organizações e das pessoas com as quais interagem. Usamos o quadro de análise de Peterson e Seligman (2004), abarcando vinte e quatro forças do carácter, que se agrupam em seis virtudes nucleares (sabedoria/discernimento, coragem, humanidade, justiça, temperança e transcendência). O texto inspira-se na tese de Ghoshal e Moran (2005), segundo a qual as teorias da gestão devem ser correctas e boas ­ ou seja, assentes em fundamentos teóricos e empíricos apropriados e obedecendo a critérios éticos e justos. É nosso objectivo sugerir que líderes globais virtuosos podem contribuir para fomentar o desempenho organizacional e criar um mundo mais justo e sustentável para os humanos.


We show how virtues and character strengths help global leaders to be more effective and promote the positive performance of organizations and people with whom they interact. We use de framework proposed by Peterson and Seligman (2004), which embraces twenty four character strengths grouped in six core virtues (wisdom and knowledge, courage, justice, humanity, temperance, and transcendence). The article is inspired by the idea Ghoshal and Moran (2005), who argued that management theories must be both right and good. We suggest that virtuous global leaders may promote positive organizational performance and contribute to build a more fair and sustainable world.

O texto inspira-se na tese de Ghoshal e Moran (2005), segundo a qual as teorias da gestão devem ser correctas e boas – ou seja, assentes em fundamentos teóricos e empíricos apropriados e obedecendo a critérios éticos e justos. É nosso objectivo sugerir que líderes globais virtuosos podem contribuir para fomentar o desempenho organizacional e criar um mundo mais justo e sustentável para os humanos.(AU)
