Element Variation

In this study, an algorithm to identify the maneuvers of a satellite is developed by comparing the Keplerian elements acquired from the two-line elements (TLEs) and Keplerian elements propagated from simplified perturbation models. TLEs contain a specific set of orbital elements, whereas the simplified perturbation models are used to propagate the state vectors at a given time. By comparing the corresponding Keplerian elements derived from both methods, a satellite’s maneuver is identified. This article provides an outline of the working methodology and efficacy of the method. The function of this approach is evaluated in two case studies, i.e., TOPEX/Poseidon and Envisat, whose maneuver histories are available. The same method is implemented to identify the station-keeping maneuvers for TDRS-3, whose maneuver history is not available. Results derived from the analysis indicate that maneuvers with a magnitude of even as low as cm/s are detected when the detection parameters are calibrated properly.

Saving Behavior

Nowadays, a lot of people engage in unsustainable daily behavior unconsciously, although most of them worry about the state of our natural environment. Designers can find ideas in people’s unconscious saving behavior and wasting behavior, and then realize these ideas into design. Based upon the case studies, the paper gives hints how to realize ideas derived from unconscious behavior into sustainable design.

In this article we develop the notion of 'organising around ideas'. We highlight the ways in which education debate in England has narrowed as traditional spaces for discussion and debate have been closed down. The state now has extraordinary power to shape discourses and frame narratives about the purposes of schooling. Here we argue that we must find new ways to engage in the battle of ideas, not simply as an exercise in rational argument, but as an essential element of organising and movement building. The article provides three short case studies of 'organising around ideas' in action to illustrate what this work can look like. The cases are not templates, but illustrate the flexible, grassroots-based activity that is central to building a movement from the bottom up.

Abstract Discourses around illicit markets for irregular migration focus on criminality and global dimensions threatening border security and the sovereignty of the state. Organised crime has generally been understood to be committed by crime syndicates outside or parallel to the dominant order and formal economy. In Malaysia and Indonesia, however, the state (or parts thereof) is heavily implicated in such crime and essential for the success of unsanctioned trans-border movements. The participation of state officials could be analysed as a convergence of extralegal income generation and symbolic law enforcement. This article presents case studies from Malaysia and Indonesia that could only have taken place because security officials facilitated them. It challenges the orthodoxy of a state versus criminal network opposition and seeks to explain the circumstances under which legal prosecution occurs. The symbolic punishment of low-ranking officials reinforces networks of control, power hierarchies and cooperation of the state in illicit markets.

False Accusations

This chapter focuses on the official correspondence between Vidin’s administrative council and the provincial capital, Ruse. These reports pertaining to events in Vidin County were a part of the political procedures of the local judicio-administrative sphere. As such, politics of local administration influenced the official correspondence and our understanding of the events in Vidin County. The writing of reports and petitions and other provincial administrative/judicial practices (such as interrogations) constituted a significant part of Ottoman governmentality. Those who could shape how the official correspondence was constructed gained advantage in local political economy. Such correspondence was an essential component of how provincial Ottoman government functioned; therefore, reports, petitions, false accusations, and interrogations became important tools for agents and groups who were engaged in hegemonic negotiations. Both elite and non-elite agents were able to utilize Ottoman governance to pursue their own strategies against other local agents or imperial government. People who refused to use these bureaucratic tools in making claims and negotiating were presented in this correspondence as defiant stubborn and violent. This perspective is critical of the state–society divide, as the case studies reveal a more complex singular government of state and society.

Child Rape

This study is the analysis of child rape incidence in Karnataka. This is a socio legal study of Laws regulation and case studies in relation to minor child rape victims from 2010 to 2016, and few data till June 2017 of Karnataka. The results show that at the state level total minor rape victims continuously increased during the study period and the major proportion of rape victims belong to Bangalore Metropolitan city ,the study also states that young kids have most often more vulnerable of rape than the adolescences’. Earlier the offences of child abuse is tried under different Acts, in the state of Karnataka but after implementation of POSCO Act 2012 (Protection of Children from sexual offences), cases of child rape are tried under POSCO Act 2012. The maximum punishment awarded to the offender under this Act is 10 years. To find out solution to the social evil there is a strong need to strictly implement the judicial and legislative recommendation in reasonable manner along with strict punishment to accused so that people afraid to do such crimes.

In its depictions of Guantánamo Bay detainees, the state’s agenda is obvious. But the state is not the only entity that mediates detainees’ voices: so, too, do the individuals and organizations that work on their behalf. Reading the history of anti-Guantánamo activism, the chapter demonstrates that it often relies on an erasure of detainee political subjectivity and a refusal of the possibility of detainee anger. Three case studies bear this out. First, a set of city-council resolutions from Massachusetts and California that extended hypothetical welcomes to select detainees on their hypothetical release; the chapter queries the politics of this deeply conditional hospitality and the presumptions of American exceptionalism underpinning it. American exceptionalism is central to the analysis of the next object, the Witness to Guantánamo documentary project, which collects testimonies from former detainees. W2G does crucial documentary work, but its structure also compels the detainees to offer forgiveness and recuperative visions of American goodness. Next, the chapter explores the politics of detainee creative production, with a particular attention to practices of circulation and consumption, and the fictive experiences of intimacy that they promise their audiences. The chapter ends with a critique of a fanciful renarration of Guantánamo’s past and future.

Use Of Social Media

In this chapter, the authors show two case studies of the use of social media in municipal governments: Lerma, a small municipality with a significant growth, and Metepec, an important municipality of the State of México. The purpose of this chapter is to provide empirical evidence of how social media improves government to citizen relationship and promotes e-participation in municipal governments. The results are based on semi-structured interviews applied to public servants and a survey to evaluate e-government services by citizens. So, the citizen perception is contrasted with public servants' interviews. Citizens consider that electronic procedures and services implemented by their municipalities do not generate value. The efforts of governments should focus on avoiding corruption, making governments transparent, opening data, and properly managing the privacy of information.

Child Agency

Childhood is believed to be a stage that requires protection, both in national and international policymaking realms. This essay looks at a few such intersections where lives of certain ‘categories’ of children have been gravely affected by laws meant for their protection and rehabilitation. Through detailed exploration of the making of the anti-child labour law and the category of railway children, this essay argues that repeatedly rehashed state plans of action to address child labour or children in railways situation are dysfunctional because they have abysmally failed to address it with the depth, diversity, and comprehensiveness required. This essay, touching upon case studies of child labour rescue raids conducted by the state in collaboration with NGOs and ethnographic accounts of children who have been rescued, and children who have defined their life and work in their own ways, attempts to explore how ‘childhood’ and ‘child agency’ have become a contested site between children, the existing state and NGO/legal activist/child rights groups discourses on child protection.
