A segurança à navegação é um fator primordial para garantir aos navios acesso aos portos. Obras de dragagens são necessárias para a manutenção dos canais de navegação diante do processo de assoreamento em regiões estuarinas. Entretanto, o volume, em metros cúbicos dragados, na região portuária do Complexo Estuarino de Paranaguá (CEP), aumentou ao longo do tempo. O presente estudo se restringe aos setores que interessam à navegação e às instalações portuárias, isto é, o eixo E-W do CEP, que abrange os trechos do canal de acesso aos portos paranaenses nas baías de Paranaguá e Antonina. O total de sedimentos realocados entre 1999 e 2018 nos trechos do canal foi da ordem de 42.517.662,79 m³. A manutenção destes setores é extremamente onerosa, uma vez que mais de 4.000.000 m³.a-1 de material sedimentar são retirados atualmente para garantir acessibilidade aos navios. Ao estimar a produção de sedimentos na área de drenagem do CEP, obteve-se o valor anual de 197.017,23 ton. Dessa forma, torna-se necessário desenvolver estratégias para a retenção de sedimentos nas áreas fonte, a fim de garantir a prosperidade das atividades portuárias nos próximos anos. Recomendações à expansão dos portos na região foram apresentadas ao final.  Silting in the Bays of Antonina and Paranaguá - PR: Integrated Analysis of Sedimentation Sources and Dragging WorksA B S T R A C TSafety in navigation is a primordial aspect to the ports. Dredging works are necessary for the maintenance of the navigation channels before the process of silting in estuarine regions. However, the volume in cubic meters dredged in the port region of the Paranaguá Estuary Complex (CEP) has increased over time. This study is restricted to sectors that are of interest to navigation and to port installation, in other words, the E-W axis of the CEP that includes the sections of the access channel to the ports of Paraná in the bays of Paranaguá and Antonina. The total of relocated sediments between 1999 and 2018 in the canal segments is of the order of 42.517.662,79 m³. The maintenance of these sectors becomes extremely costly, since more than 4.000.000 m³.a-1 of sedimentary material is removed to guarantee accessibility to the ships. When estimating the sediment production in the CEP drainage area, the annual value of 197,017.23 tons is obtained. Thus, it becomes necessary to develop strategies for retaining sediments in the source areas, in order to guarantee the prosperity of port activities in the coming years. Recommendations for expanding ports in the region were presented at the end.Keywords: Hydrographic Units. Sedimentary Dynamics. Sedimentary Disposal. Port Environmental Management.

The aim of this study is to characterize the Pirapó, Paranapanema 3 and 4 Hydrographic Unit, emphasizing its physical attributes and processes of use and occupation, responsible for the structure of the current landscape and the state of its water resources. The recognition of the landscape’s spatial structure in the hydrographic unit and its drainage basins was obtained by integrated analysis of the main elements that compose it: geology, landforms (hypsometric and slope), soils, climate and land use. Analysis revealed that within each drainage basin several variations in the spatial structure of the landscape occur which produce an internal compartmentalization. Each compartment is defined by its own geo-ecological structure, physiognomic standards and dynamics, reflected in its potentialities and vulnerabilities and in the conditions of water resources in the wake of occupation and use over time.

Purpose The purpose of this paper is to explore how national cultures contribute to explain the uneven diffusion of ISO 14001 across countries. The paper focuses on two of the cultural dimensions developed by the global leadership and organizational behavior effectiveness (GLOBE) project, namely, performance orientation and institutional collectivism. Design/methodology/approach A database containing information about the diffusion of ISO 14001 in 52 countries during the period 1999–2016 was built to carry out this research. The countries considered in this study represent about 90 percent of worldwide ISO 14001 certifications. The information was gathered from publicly available data sources: the ISO Survey, published every year by the International Organization for Standardization, the world development indicators of the World Bank, the cultural dimensions of the GLOBE project and the Index of Economic Freedom provided by The Heritage Foundation. Findings This research finds that both performance orientation and institutional collectivism influence the diffusion of ISO 14001. Whereas performance orientation slows down the diffusion of ISO 14001, institutional collectivism speeds it up. Additionally, this research shows that the slowing effect of performance orientation decreases in strength over time, while the accelerating effect of institutional collectivism becomes stronger. Originality/value The study adds to the understanding of the influence of national culture on the diffusion of environmental management standards, with an emphasis on ISO 14001. A key contribution of this research is that it explores how the influence of cultural dimensions change over time as a result of the development and maturation of ISO 14001.

Life cycle management (LCM) is a concept that goes beyond traditional corporate environmental management, due to its focus on a product’s entire life cycle. The spread of such concepts is usually understood in terms of processes of “diffusion,” whereby ideas spread over time by some inexplicable force. However, diffusion has proven less adequate to describe how ideas spreads in practice. Here, we address this oversight by studying the emergence and performance of what we refer to as life cycle practices. Drawing on an analysis of the development of a sustainability portfolio within a globally operating manufacturing company, we illustrate the kinds of life cycle work involved in dealing with local activities and interests, connecting activities and interests into action nets, performing life cycle practices, and spreading the life cycle idea. Finally, we discuss implications of life cycle work for research in the field of organization and management studies and for LCM research.

Critical aspects of the environment can reduce the efficiency of Environmental Management Systems (EMS) when applied to Marine Transport. Accordingly, this paper focuses on the improvement of the traditional EMS approach through the usage of Balanced Scorecard (BSC). The BSC represents a managing tool able to measure and increase organizational performance, taking into consideration environmental aspects. The proposed method, based on the ISO 14001 standard, allows management of environmental metrics through conventional BSC systems and it is applied to the biggest organization for marine transport in Montenegro as a case study methodology. In this qualitative investigation, particular attention was paid to creating EMS criteria able to orient the complete business operation of the organization but also to test their potential linkage to the conventional BSC approach. Four models of the BSC were created, each one including to a different extent the issue of environmental protection. Finally, an expert’s evaluation of model efficiency, based on the ISO 9126, was carried out. As a result, the best ranked model is recommended for the selection of an approach toward environmental protection based on the use of the EMS metric in a conventional BSC system. This method—in short ECO-BSC—was developed for the specific benefit of those organizations operating on the marine transport market.

The aim of environmental impact assessment (EIA) is to ensure effective environmental management outcomes for development projects. Some argue it has failed to achieve this, because environmental management activities are not properly planned in the EIA process. The extent of this problem is largely unknown, due to a lack of empirical evidence. This paper presents the results of research investigating environmental management planning within EIA in the state of Queensland, Australia. The study examined environmental management commitments within 285 environmental impact statements (EISs). The majority of the EISs contained environmental monitoring and mitigation commitments and more than half identified corrective actions. This suggests that EIA facilitated environmental management within some developments. Nevertheless, many environmental management activities were not addressed in EISs, even when specifically requested. Trends in environmental management planning over time revealed dramatic improvements. These appeared to have resulted from an increase in government requirements for, and the provision of guidelines to assist, environmental management planning. These findings suggest improved environmental management must be facilitated by government agencies, rather than relying upon industry innovation.

A river is an important part of the social and environmental management in West Kalimantan which becomes a marker of the community’s existence. Literature is the image of the management since it lives and develops according to its surrounding. The relationship between literature and rivers can be seen in the literary expressions The image of the river in literature changes over time which is seen in different expression of West Kalimantan’s poem. This paper used semiotic-dynamic as an analytical tool to find out the expressions of the river and its changes in literary expression. This analysis tool was used to obtain the dynamics of these literary expressions. In addition, an ecocritical method was also used to see the direction of river-related literary expression in West Kalimantan’s literature. The results show that the existence of rivers is an important pillar of people’s life in West Kalimantan as emphasized through literary works.

Purpose – The purpose of this paper is to build upon the conceptual model developed by Feldman et al. (1997) that demonstrated a link between improved environmental performance and increased market value for publicly traded corporations. ISO 14000 standards, not yet established at the time of their study, provide the framework for a strategic approach to environmental management with an emphasis on continuous quality improvement. Consequently, ISO 14000 certification is used as the basis for creating an investment portfolio of publicly traded companies. While previous research has examined short-term stock market reactions to ISO 14000 certification, this study evaluates the longer term impact on shareholder value by comparing the ISO portfolio’s performance against other funds. It adds to the existing literature on the “pay to be green” question. Design/methodology/approach – The successful attainment of ISO 14000 certification is used as the basis for developing a portfolio that is followed over time in order to examine its value to shareholders. The portfolio consists of companies certified between 1996 and 2006, each added to the portfolio the month after its announced ISO 14000 certification date. The study covers the period from October 1996 through April 2011. Average monthly returns and standard deviations for a buy-and-hold strategy over various rolling periods (three, five, seven and ten year) are used to compare the ISO 14000 portfolio against the S&P 500 Index. In addition, the growth of an initial investment of $100,000 is tracked to compare the ISO 14000 portfolio against the S&P 500 Index and three other funds that are socially responsible and/or green (Domini Social Equity Fund (DSEFX), Winslow Green Growth Investment, and iShares KLD 400 Social Index). Findings – The ISO 14000 portfolio outperformed the S&P 500 Index as well as selected socially responsible and/or green funds in the growth of an initial investment over time. It also consistently provided higher average monthly returns (along with higher standard deviations) than the S&P 500 Index when using a buy-and-hold investment strategy over all rolling periods considered. Moreover, monthly returns for the ISO 14000 portfolio were found to be significantly higher, at the 0.05 level, than for those of the S&P 500 Index and the DSEFX. Research limitations/implications – Companies that attained ISO 14000 certification after 2006 were not included in the portfolio due to the inability to obtain a complete listing after that time. Furthermore, causality cannot be established by analyzing fund performance. Nonetheless, ISO 14000 certification as the basis for creating an investment portfolio appears to be a strategy that pays off in the long term. Originality/value – This paper fills a gap in the literature by examining longer term market reactions to ISO 14000 certification. The methodology employed has not been used in this context, although it has been used to examine the impact of ISO 9000 certification on stock prices. The findings support the argument that improved environmental performance is valued by the market and may provide long-term value for shareholders.

Abstract Background Baricitinib (BARI) is a selective inhibitor of janus kinase (JAK) 1 and JAK2, approved for the treatment of moderately to severely active rheumatoid arthritis (RA) in adults in over 50 countries. Objective: To evaluate the long-term safety of BARI in patients with RA with a specific focus on malignancies, major adverse cardiovascular events (MACE), serious infections and herpes zoster (HZ) events. Methods Data from nine completed studies (5 Phase 3, 3 Phase 2, 1 Phase 1b) and 1 long term extension (LTE) study were pooled for this analysis (data cut-off date: 13-Feb-2018). The all BARI data set included all patients exposed to any BARI dose. Results A total of 3,770 patients with RA were treated with BARI (10,127 patient years [PY]) with a maximum exposure of 7 years. Of these, 2,938 (78%) and 1,754 (47%) were on concomitant methotrexate or corticosteroids (CS; mean dose 6.2 mg/day), respectively. The incidence rates (IR) of malignancy (excluding non-melanoma skin cancer) were 0.8 (2-mg) and 1.0 (4-mg; as-randomized analysis) in the LTE. The IRs for MACE were similar between the all BARI and PBO group; however, the IR for DVT/PE were numerically higher in the BARI 4mg group during the PBO-controlled period. IRs for MACE remain stable over time. The IR of serious infections were numerically higher in the PBO group; the IR of tuberculosis and other opportunistic infections were similar between the all BARI and PBO group. During the PBO-controlled period, HZ IR was significantly higher for BARI 4-mg versus PBO (4.4 vs 1.1) (Table 1). Amongst 323 HZ patients, 11 (4%) had received prior HZ vaccination. Twenty-six [8%] cases were multidermatomal, and no visceral disease was reported. Multivariate analyses showed that older age and some geographical regions (Asia, especially Japan, Taiwan and South Korea) were associated with a higher risk of HZ. Conclusion This integrated analysis in patients with active RA exposed to BARI for up to 7 years shows that the safety profile of BARI is like that reported previously. The IRs of malignancies, MACE (including DVT/PE), serious infection, and HZ did not increase over time. Disclosures D. Walker: Honoraria; Lilly, Pfizer, Giliad, Novartis, Roche.
