Having identified all the dominant factors and having puttogether a mosaic of all the factors resulting from a ship 's voyage,as well as a number of differently dimensioned criteria, theharmfulness evaluation method for water ballast managementon board has been elaborated. By careful analysis of the impactfactors to which status elements are adjoined, by the assignmentof harmfulness levels to the status elements, by determiningdifficulty factor values, by introduction of treatment methodsi.e. exchange of water ballast, certain characteristic managementscenarios according to ship type are developed. Cumulativescenarios provide insight into the total harmfulness ofwater ballast management. The introduction of a comprehensiveapproach results in the development of different scenariosapplicable to all ships. The established harmfulness evaluationmethod for water ballast management is applicable to all shiptypes, and it has been tested on various types of ships that weredischarging ballast in various ports worldwide.

In 1887 Dutch archivist A. J. Servaas van Rooijen published a transcript of a hand-written copy of an anonymous missive or letter, dated 1631, about a horrific famine and epidemic in Surat, India, and also an important description of the fauna of Mauritius. The missive may have been written by a lawyer acting on behalf of the Dutch East India Company (VOC). It not only gives details about the famine, but also provides a unique insight into the status of endemic and introduced Mauritius species, at a time when the island was mostly uninhabited and used only as a replenishment station by visiting ships. Reports from this period are very rare. Unfortunately, Servaas van Rooijen failed to mention the location of the missive, so its whereabouts remained unknown; as a result, it has only been available as a secondary source. Our recent rediscovery of the original hand-written copy provides details about the events that took place in Surat and Mauritius in 1631–1632. A full English translation of the missive is appended.

Written almost half a century apart, Rajmohan’s Wife (1864) and The Home and the World (1916) can be read as women centric texts written in colonial India. The plot of both the texts is set in Bengal, the cultural and political centre of colonial India. Rajmohan’s Wife, arguably the first Indian English novel, is one of the first novels to realistically represent ‘Woman’ in the nineteenth century. Set in a newly emerging society of India, it provides an insight into the status of women, their susceptibility and dependence on men. The Home and the World, written at the height of Swadeshi movement in Bengal, presents its woman protagonist in a much progressive space. The paper closely examines these two texts and argues that women enact their agency in relational spaces which leads to the process of their ‘becoming’. The paper analyses this journey of the progress of the self, which starts with Matangini and culminates in Bimala. The paper concludes that women’s journey to emancipation is symbolic of the journey of the nation to independence.

The introduction of series capacitors in transmission lines causes problems in terms of reliability and the security of distance protection relays. As distance protection is widely used in the transmission network, the challenge of applying it to series compensated lines has been taken up by utilities and relay manufacturers in various ways. In the field of power system protection, developments are largely driven by relay manufacturers, and are often not published in the academic literature; the status and trend of the relay manufacturer’s development are better found in their product manuals and patent activity. Further insight into specific implementations by transmission utilities can be found from publications in industry-led forums and some academic journals. This article surveys the status and development of distance protection for series compensated lines, with a focus on industrial implementation and practical considerations. Factors that influence the protection of series compensated lines are presented. Implementation examples reported by utilities are summarized as examples of the different situations encountered and the methods used to deal with them. It is observed that many utilities use communication-aided protection in series compensated lines, and distance protection is used with reduced reach. Solutions described in relay manuals are presented to demonstrate the manufacturers’ approaches to problems associated with series capacitor protection. While there are methods to counter voltage inversion, current inversion seems to represent a more serious challenge. A patent overview indicates the trends in this domain to be moving towards time-domain-based faster protection methods.

Idiopathic intracranial hypertension (IIH) is a debilitating condition that has traditionally been difficult to treat. In recent years, there has been increasing focus on the role of intracranial venous hypertension in the pathophysiology of IIH. Based on increased understanding of this pathophysiology, venous sinus stenting (VSS) has emerged as a safe and reliable treatment for a certain population of patients with IIH. Stratifying patients with IIH based on the status of their venous outflow can provide insight into which patients may enjoy reduction in their symptoms after VSS and provides information regarding why some patients may have symptom recurrence. The traditional view of IIH as a disease due to obesity in young women has been cast into doubt as the understanding of the role of intracranial venous hypertension has improved.

Today Pierre Bourdieu is well known as one of the most important social scientists of the 20th century. One of the outstanding qualities of his work has been his innovative combination of different methods and research strategies as well as his analytical skills in interpreting the obtained data (his ‘sociological gaze’). In this paper, we attempt to retrace the development of an extraordinary way of doing social research and show the benefit of Bourdieu's visual sociology for his empirical fieldwork and sociological theory. The article particularly stresses the significance of his photographic archive, which has long been ignored within the appreciation of Bourdieu's work. Studying Bourdieu's photography gives access to his æuvre in several new ways: not only can we understand how Bourdieu became an unconventional sociologist practicing his craft in the midst of a colonial war. Bourdieu's visual anthropology also offers an insight into the status nascendi of Bourdieu's sociology in all its elementary forms and contents. Through his photography Boudieu demonstrated the concepts of ‘ habitat and habitus’, the material and symbolic living conditions of the Algerian population.

Product development processes of complex products are complex themselves and particularly difficult to plan and manage effectively. Although many organizations manage their product development processes by monitoring the status of documents that are created as deliverables, in fact the progress of the process is in large part based on the actual information flow which is required to develop the product and produce the documents. A vital element in making product development processes work well is the correct understanding of how information flows and how to facilitate its development. In this paper we describe an executable stochastic model of the product development process that incorporates the salient features of the interplay between the information development, exchange and progress of the technical work. Experiments with the model provide insight into the mechanisms that drive these complex processes.

Abstract X-ray Photoelectron Spectroscopy (XPS) has been used to study the interactions of heavy metal ions with DNA with some success. Surface sensitivity and selectivity of XPS are advantageous for identifying and characterizing the chemical and elemental structure of the DNA to metal interaction. This review summarizes the status of what amounts to a large part of the photoemission investigations of biomolecule interactions with metals and offers insight into the mechanism for heavy metal-bio interface interactions. Specifically, it is seen that metal interaction with DNA results in conformational changes in the DNA structure.

This study sought to understand interpretations of interconnections between historical trauma, contemporary violence, and resilience in a Maya Achi community currently engaged in promoting peace and social change through popular education. In particular, the ways in which participants drew upon identity and memory in articulating characteristics of community distress and resilience are discussed. The research is informed by liberation psychology and critical perspectives of mental health, particularly considering the challenges inherent in the promotion of collective memory of trauma and resistance in contexts of violence and humanitarian settings. Participant reflections on historical and contemporary violence highlight elements of collective distress, connecting identity and memory with acts of both oppression and resistance. Education and development are signaled as possible sites of resilience but also experienced as sites of power upholding the status quo. Diverse experiences and applications of identity and memory provide insight into the ways in which community organizations working in contexts of political violence might navigate polarizing and paradoxical discourses in order to subvert, co-opt, or adapt to hegemonic cultural, political, and economic power relations in the process of transformation for collective resilience.

To scientifically and accurately evaluate the status of the development of green airports in China, evaluation methods of green, ecological airports are established in this paper. To address the shortcomings in subjective and objective weighting methods, we propose a combination weighting method based on Spearman’s rank correlation coefficient and evaluation grades based on interval approximation. At the same time, by taking into account resource conservation, environmental friendliness, operation efficiency, and people-oriented service, we propose an evaluation index system and an interval number for each index. Lastly, the theory is applied to five large airports in different regions of China. Analysis of the evaluation results shows that Shanghai Pudong International Airport (PVG) and Guangzhou Baiyun International Airport (CAN) have the highest scores for the resource conservation and environmental friendliness indexes, thus indicating that the development of a green ecological airport is closely related to its passenger transportation scale and economic strength. All considered airports showed the need for upgrading public  service facilities and constructing intelligent equipment. The method proposed in this paper is reasonable  and reliable; therefore, it can provide guidance for the evaluation and construction of green, ecological  airports.

In May 2016, artist, researcher and activist, Manu Luksch, travelled to the United Arab Emirates (USE) to conduct research on ‘smart city’ initiatives in the region, and also to interview renowned human rights defender, Ahmed Mansoor. In March 2017, Mansoor was re-arrested, and on May 28th 2017, he was sentenced to 10 years’ imprisonment. Organisations like Amnesty International, Human Rights Watch and many others are campaigning for his release and #FreeAhmed has become a call online and on the streets in the form of graffiti and posters. Meanwhile the UAE has been one of 4 Gulf states, led by Saudi Arabia, who have extended their authoritarian campaign against dissidence beyond their borders to target other states who they regard as threatening the status quo, in particular the small but very wealthy state of Qatar, home of the Al-Jazeera news network that has, like Mansoor, championed opposition movements in the Middle-East. In this context, Surveillance & Society decided it was important to publish this interview almost in full as it gives unique insight into the personal and professional experience of a human rights defender in an authoritarian state that is at the same time extremely wealthy, technologically advanced and highly integrated into global capitalism.
