Sustainable development goals – an analysis of outcomes

Purpose: The concept of sustainability evokes a multiplicity of meanings, depending on the field. Some authors have criticized the concept for its vagueness. Notwithstanding this criticism, worldwide efforts to meet the sustainable development goals (SDGs) are in progress and are expected to yield results by 2030. This paper aims to addresses two issues and make two primary contributions. First, the concept of sustainability is revisited to develop its integrative understanding. This concept is built on systems thinking – specifically, on the concepts of synergy, emergence, recursion and self-organization. Second, an approach is developed to help determine whether the efforts being made towards the SDGs can be expected to be effective (i.e., whether the world can hope to soon be a system that self-organizes towards sustainability). Design/methodology/approach: Based on the assumption that the SDGs and their respective targets are systemically interrelated, the data on the progress towards the SDGs are correlated and the outcome is analysed. Findings: The emerging pattern of correlations reflected the systemic coherence of the efforts as an indication of self-organization towards sustainability. This pattern also revealed that the efforts are still spotty and that the systemic synergy has not yet taken place. This correlation approach to Brazil is then applied. The data about Brazil’s progress towards the SDGs from the World Bank’s Word Development Indicators (WDI) database are gathered. The outcomes indicated that Brazil as a whole cannot yet be seen as self-organizing system that is evolving towards sustainability. Research limitations/implications: To enable the calculation of the correlation matrix, the data series were not allowed to have missing values. Some of the WDI data series had many missing values and had to be eliminated. This unfortunately reduced the variability of the original data. In addition, the missing values in the remaining data series had to be calculated by means of interpolation or extrapolation. There are alternative algorithms to perform such functions. The impact of the interpolation and extrapolation of the missing values on the study, as well as the pros and cons of different algorithms, required investigation. It is important to remark that the WDI series was the only global and open data set that aligned with the SDGs. Social implications: In Brazil, it is important to maintain the public policies that affect SDG 1-6, but it is necessary to develop policies geared towards SDG 12. Environmental goals also need more public policies (SDGs 14 and 15). To achieve this 2030 Agenda, much effort will be required for SDG 17, which is related to greater synergy through partnerships. Originality/value: Three qualitatively distinct levels of efforts to sustainability are identified: individual, organizational and world activities. At the individual level, progress regarding sustainability depends on personal attitudes, including the willingness to abandon a self-centred lifestyle in favour of a more cooperative way of living and making decisions, and to embrace a new approach to ethics, which replaces self-interest by self-denial and self-sacrifice (de Raadt & de Raadt, 2014). At the organizational level, a paradox of the need to internalize environmental and social costs into generic strategies and the sustainability strategy that involves core businesses are challenges for systems working towards sustainability. When it comes to global level, in this paper, the authors tried to make a contribution to push forward the frontier of knowledge by proposing an approach to understand whether the progress made towards the SDGs in the past 25 years indicates that the world is, after all, organizing for sustainability (Schwaninger, 2015)

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

Diabetes insipidus in a pacient with multiple sclerosis

Multiple Sclerosis (ME) is a chronic progressive disease characterized by relapses of demyelination that can occur anywhere in the brain stem, spinal cord and optic nerve. Since central diabetes insipidus (DI) is mainly caused by central nervous system damage (such as trauma, surgery, tumor, infection, sarcoidosis), ME is included among its possible etiologies. However, this association is not commonly described. The clinical suspicion must be made in the presence of polyuria and polydipsia or refractory hypernatremia (in patients without free access to water) during the evolution of ME. We will describe a clinical report in which this association occurred and, after the beginning of desmopressin therapy, the clinical findings were reverted.A esclerose múltipla (EM) é uma doença crônica e progressiva que se caracteriza por surtos de desmielinização que podem atingir qualquer topografia do cérebro, medula espinhal e nervo óptico. Sendo o diabetes insípido (DI) central causado, principalmente, em virtude de danos do sistema nervoso central (tais como trauma, cirurgia, tumor, infecção, sarcoidose), a EM está inclusa entre suas possíveis etiologias. Entretanto, a ocorrência dessa associação não é comumente descrita. A suspeita clínica deve ser feita na presença de poliúria e polidipsia ou hipernatremia refratária (em pacientes privados do acesso à água) durante a evolução da EM. Descreveremos um caso em que essa associação ocorreu e, após o início da terapêutica com desmopressina, a paciente reverteu o quadro clínico.Universidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

Positive and negative aspects of GRI reporting as perceived by Brazilian organizations

This paper aims to identify the positive and negative aspects in the sustainability reporting framework proposed by the Global Reporting Initiative (GRI). The research was conducted through content analysis of 27 companies’ responses to three questions: “Why does the company where you work prepare a sustainability report?” “What are the positive aspects you identify in the framework for GRI reporting?” and “What are the negative aspects you identify in the framework for GRI reporting?” The questionnaire was sent to all Brazilian companies that published sustainability reports using the GRI guidelines between 2011 and 2013 related to the base year 2010. We found that respondents viewed the GRI guidelines and the reports they created as management tools for sustainability and that they assist in benchmarking sustainability performance and legitimizing the sustainability actions of the organization. Furthermore, some respondents indicated that the reports themselves are marketing tools. On the other hand, the respondents reported difficulties in understanding the proposed GRI guidelines. They considered the guidelines complex, ambiguous, and too flexible, which undermined both the standardization of the reports and the ability to compare reports. Based on these comments, it is recommended that the GRI develop a simpler and less flexible reporting methodology

Image segmentation with traveling waves in an exactly solvable recurrent neural network

We study image segmentation using spatiotemporal dynamics in a recurrent neural network where the state of each unit is given by a complex number. We show that this network generates sophisticated spatiotemporal dynamics that can effectively divide an image into groups according to a scene's structural characteristics. Using an exact solution of the recurrent network's dynamics, we present a precise description of the mechanism underlying object segmentation in this network, providing a clear mathematical interpretation of how the network performs this task. We then demonstrate a simple algorithm for object segmentation that generalizes across inputs ranging from simple geometric objects in grayscale images to natural images. Object segmentation across all images is accomplished with one recurrent neural network that has a single, fixed set of weights. This demonstrates the expressive potential of recurrent neural networks when constructed using a mathematical approach that brings together their structure, dynamics, and computation

Joint Metabonomic and Instrumental Analysis for the Classification of Migraine Patients with 677-MTHFR Mutations

Migraine is a neurological disorder that correlates with an increased risk of cerebrovascular lesions. Genetic mutations of the MTHFR gene are correlated to migraine and to the increased risk of artery pathologies. Also, migraine patients show altered hematochemical parameters, linked to an impaired platelet aggregation mechanism. Hence, the vascular assessment of migraineurs is of primary importance
