Balancing skills in the digital transformation era: The future of jobs and the role of higher education
Developing human resources and matching job profiles are essential tasks to promote economic and social growth. The technology-related job market has undergone significant changes over recent years, mainly due to technological advances that have pushed industry toward new demands for skilled professionals. This change in required skills and competencies has led to a gap between what companies need and the professional profiles that are available in the job market. Technology companies are often unable to find an employee who meets the required profile, resulting in financial loss and extra training expenses. It is therefore essential that higher education in technology is reconsidered to address job market demands. Thus the goal of this work is to evaluate the relationship between the professional profile required by information technology (IT) companies and what students are taught on IT-related programs in higher education institutions (HEIs). The authors adopt a systemic perspective in three different qualitative approaches. They cross-check and link data on educational curricula acquired from interviews with IT human resource managers (HRMs) and student focus groups. The analysis reveals that HEIs must go beyond the transfer of knowledge and technical qualification in IT, promoting a comprehensive education that incorporates personal development goals, with a focus on developing social and emotional skills. The study focuses on the emerging economy of Brazil and presents findings from which other developing countries can learn. The results reveal the critical role of soft skills in the professional development and employability of students and the associated challenge for technical education. In conclusion, the authors also highlight the importance of partnerships between HEIs and HRMs as a fundamental strategy to fulfill the current skills gap
Dynamic Capabilities for Sustainability: Revealing the Systemic Key Factors
By applying systems thinking theory to capabilities literature, this paper examines the factors that support the development of dynamic capabilities towards sustainable management. For such, we conducted an in-depth single case study using Soft System Methodology (SSM) in an energy organisation from an emerging economy. Our analysis of the last twenty years of operation revealed that the organisation has developed new ways to change and adapt in a disturbing environment by integrating sustainability into three factors: (1) integrative strategy (green products, biodiversity, organic processes and self-sufficient electricity), (2) sustainable culture (sustainable mindset, environmental awareness, learning orientation and decision-making processes) and (3) organisational routines for innovation (new green processes and products, partnerships/alliances and knowledge management). Our results extend the literature by raising a conceptual framework of the fundamental dimensions of dynamic capabilities for sustainability. This is the first study that connects systems thinking and dynamic capabilities theories applied to sustainable management
Sugar-energy bioelectricity in energy trading environments: reasons for the lack of competitiveness
Purpose: Renewables such as sugar-energy biomass can contribute to national electrical security, job creation and mitigation of greenhouse gas emissions. However, after the auction of reserve energy, in 2008, exclusive biomass, in the regulated contracting environment (RCE), the authors observe that this energy environment has lost competitiveness in the auctions. Thus, a study on the present theme is justified, based on the problem: What are the reasons for the lack of competitiveness of sugar-energy bioelectricity in the Auctions of the RCE of the National Electric Energy Agency? The purpose of this study is to understand the situation of sugar-energy bioelectricity in the Brazilian market. Design/methodology/approach: Literature review was conducted through the Scientific Electronic Library Online database, as well as the survey of primary documents at Sugarcane Industry Union and Electric Energy Trading Chamber. Findings: The reasons for lack of competitiveness in RCE electricity auctions are: distant location of transmission lines; difficulties in obtaining licensing; delay in responses from environmental agencies; difficulties in securing financing for electricity generation projects for distilleries; non-pricing of positive environmental externalities as adequate disposal of waste; and the non-recovery of the cost of retrofit of the plants. The present situation may create economic, social and ecological circumstances adverse for Brazilian development, such as a lack of employment and income generation, loss of international currencies from imports of technologies not developed and produced in the country and more significant inefficiency greenhouse gas mitigation. Originality/value: The originality of this study is in the contribution to the scarce literature on the understanding of the reasons for the lack of competitiveness of the Brazilian sugarcane sector in auctions of the regulated energy environment, based on SWOT analysis and, based on this understanding, to propose solutions for the expansion of this important matrix energy
Supply chain resilience in a Covid-19 scenario: Mapping capabilities in a systemic framework
COVID-19 hits the global supply chains in a non-paradigm manner unfolding new and systemic complexity. Therefore, the unexpected and frequent disruptions forced the concern of preventing or creating supply chain resilience capabilities. This paper aims to provide theoretical and practical reflections on resilience in supply chains of essential goods during pandemics using a systems approach. Documental research was performed in order to characterize business practices in consulting reports and interviews with managers published in business communication media. Thus, a careful content analysis was carried out, including the coding and categorization of the leading practices indicated by these vehicles. We suggest categories of resilience factors as new concepts to face the new normal in the supply chains. These categories are Technology and People, Sourcing, Customer, Ecosystem, and Financial Assets. The systems approach consists of more qualified supply chain management stimulating several inputs and synchronized actions to sense and respond to the external environment dynamics
The size of juxtaluminal hypoechoic area in ultrasound images of asymptomatic carotid plaques predicts the occurrence of stroke
Objective: To test the hypothesis that the size of a juxtaluminal black (hypoechoic) area (JBA) in ultrasound images of asymptomatic carotid artery plaques predicts future ipsilateral ischemic stroke. Methods: A JBA was defined as an area of pixels with a grayscale value <25 adjacent to the lumen without a visible echogenic cap after image normalization. The size of a JBA was measured in the carotid plaque images of 1121 patients with asymptomatic carotid stenosis 50% to 99% in relation to the bulb (Asymptomatic Carotid Stenosis and Risk of Stroke study); the patients were followed for up to 8 years. Results: The JBA had a linear association with future stroke rate. The area under the receiver-operating characteristic curve was 0.816. Using Kaplan-Meier curves, the mean annual stroke rate was 0.4% in 706 patients with a JBA <4 mm 2, 1.4% in 171 patients with a JBA 4 to 8 mm2, 3.2% in 46 patients with a JBA 8 to 10 mm2, and 5% in 198 patients with a JBA >10 mm2 (P <.001). In a Cox model with ipsilateral ischemic events (amaurosis fugax, transient ischemic attack [TIA], or stroke) as the dependent variable, the JBA (<4 mm2, 4-8 mm2, >8 mm2) was still significant after adjusting for other plaque features known to be associated with increased risk, including stenosis, grayscale median, presence of discrete white areas without acoustic shadowing indicating neovascularization, plaque area, and history of contralateral TIA or stroke. Plaque area and grayscale median were not significant. Using the significant variables (stenosis, discrete white areas without acoustic shadowing, JBA, and history of contralateral TIA or stroke), this model predicted the annual risk of stroke for each patient (range, 0.1%-10.0%). The average annual stroke risk was <1% in 734 patients, 1% to 1.9% in 94 patients, 2% to 3.9% in 134 patients, 4% to 5.9% in 125 patients, and 6% to 10% in 34 patients. Conclusions: The size of a JBA is linearly related to the risk of stroke and can be used in risk stratification models. These findings need to be confirmed in future prospective studies or in the medical arm of randomized controlled studies in the presence of optimal medical therapy. In the meantime, the JBA may be used to select asymptomatic patients at high stroke risk for carotid endarterectomy and spare patients at low risk from an unnecessary operation
Asymptomatic internal carotid artery stenosis and cerebrovascular risk stratification
Background The purpose of this study was to determine the cerebrovascular risk stratification potential of baseline degree of stenosis, clinical features, and ultrasonic plaque characteristics in patients with asymptomatic internal carotid artery (ICA) stenosis. Methods This was a prospective, multicenter, cohort study of patients undergoing medical intervention for vascular disease. Hazard ratios for ICA stenosis, clinical features, and plaque texture features associated with ipsilateral cerebrovascular or retinal ischemic (CORI) events were calculated using proportional hazards models. Results A total of 1121 patients with 50% to 99% asymptomatic ICA stenosis in relation to the bulb (European Carotid Surgery Trial [ECST] method) were followed-up for 6 to 96 months (mean, 48). A total of 130 ipsilateral CORI events occurred. Severity of stenosis, age, systolic blood pressure, increased serum creatinine, smoking history of more than 10 pack-years, history of contralateral transient ischemic attacks (TIAs) or stroke, low grayscale median (GSM), increased plaque area, plaque types 1, 2, and 3, and the presence of discrete white areas (DWAs) without acoustic shadowing were associated with increased risk. Receiver operating characteristic (ROC) curves were constructed for predicted risk versus observed CORI events as a measure of model validity. The areas under the ROC curves for a model of stenosis alone, a model of stenosis combined with clinical features and a model of stenosis combined with clinical, and plaque features were 0.59 (95% confidence interval [CI] 0.54-0.64), 0.66 (0.62-0.72), and 0.82 (0.78-0.86), respectively. In the last model, stenosis, history of contralateral TIAs or stroke, GSM, plaque area, and DWAs were independent predictors of ipsilateral CORI events. Combinations of these could stratify patients into different levels of risk for ipsilateral CORI and stroke, with predicted risk close to observed risk. Of the 923 patients with <70% stenosis, the predicted cumulative 5-year stroke rate was <5% in 495, 5% to 9.9% in 202, 10% to 19.9% in 142, and <20% in 84 patients. Conclusion Cerebrovascular risk stratification is possible using a combination of clinical and ultrasonic plaque features. These findings need to be validated in additional prospective studies of patients receiving optimal medical intervention alone. Copyright © 2010 by the Society for Vascular Surgery
Electric utility 4.0: Trends and challenges towards process safety and environmental protection
The traditional manufacturing business model is changing for new emerging models. Many changes are related to the industry 4.0 challenge and among them there is a concern regarding how industries will meet the objectives of sustainable operations, especially on that of environmental protection and process safety. Some industries are making great efforts to get aligned with the industry 4.0 paradigm, and for the Electric System Industry, it is no different. Because of its strategic and environmental importance, the electric system industry must be investigated. In this article we used qualitative research based on a systemic approach, using the Soft System Methodology (SSM) to address the challenges brought by the industry 4.0 paradigm in the electric system industry in Brazil, focusing on the topic of environmental protection and process safety. Moreover, we point out important capabilities needed by these companies to keep up with the new industrial revolution. Results from the SSM have exposed important management gaps and hence have shown new possible management models that can contribute to the modernization of the electric utilities in Brazil, making these industries more sustainable. In fact, it is imperative for companies to detail the organizational capabilities they will need to thrive in the business process. Therefore, we conclude the paper by indicating the three main dynamic capabilities that have emerged: new policies to enable innovation, bureaucracy reduction, and investments in education
Sustainability as a dynamic capacity: Evidence in a Brazilian sugarcane energy company
Environmental concerns have increased the awareness of the limitations of the modern conception of nature and its disastrous consequences. Corporate sustainability consists of ensuring long-term economic viability and, at the same time, contributing to the socioeconomic development of communities, the health of the environment and the stability of society (Ethos, 2009). The concept of corporate sustainability involves sustainable economic growth that is aligned with social development and environmental conservation. Consequently, a new development strategy emerges embodying political, economic, social, technological, and environmental dimensions. This new paradigm of a sustainable development implies the need for profound changes in the current production systems, human society organisation, and utilisation of natural resources essential to human life and other living beings (Belico et. al, 2000). Therefore, the paradigm of sustainability implies the need for changes in the current production systems, including human society organization and utilization of natural resources essential to human life and other living beings (Liboni; Cezarino, 2014).The aim of this paper is to analyze the development of changes in operations management towards sustainability using the Soft System Methodology. The results show that Balbo company, Brazilian sugarcane industry, has developed new ways to change and adapt in a disturbing environment was able to built dynamics capabilities. SSM is a soft methodology, which was developed from the observation that not all problems and situations faced by corporations are of a precise nature (Martinelli and Ventura, 2006, p. 163). This systemic method was "designed to assist in the resolution of soft issues, which are of complex nature and involve many human elements" (Martinelli; Ventura, 2006, p.163). Native branch and all the changes demanded by the company's new business were the source of development of dynamic capacities and adaptation of the company, which shifted from a stable commodity market to a dynamic, increasing market of organic food products. In order to seek a more sustainable management model, the company has developed dynamic capacities within the economic sphere focusing on efficacy, reduction and reuse of solid wastes, and cogeneration of energy; within the social sphere, the rural workers are assisted with security and quality of life programs; and within the environmental sphere, the company, through the Cana Verde project, has environmental certifications and preserves protected areas by conciliating the respect for the environment with the production processes of all areas
