Haptic mobility control for teleoperated rovers

Future missions involving human and robotic systems co-resident on the lunar surface may call for rovers to be teleoperated from the safety of pressurized habitats or vehicles. An approach is presented that emphasizes human-level judgment and intuition in the total control of a rover’s mobility actions. This is facilitated through human-robotic haptics interaction. The concept of a haptics cone control surface is presented, which provides a teleoperator with a means to intuitively determine the velocities he/she is commanding to control rover motion. The teleoperator is also provided with real-time, tasks-relevant haptic augmentation indicating suggestive control actions concerning the desired mobility objective. Utility of the approach for teleoperated control of steep terrain traversal is demonstrated in simulation.

UN-consistent : a comparison of Australia's military interventions in Somalia and Rwanda

This article seeks to compare Australia's involvement in two key 1990s peace missions: those to Somalia in 1992-93 and Rwanda in 1994-95. While there are many similarities between the two missions in terms of time, scale and theatre, the differences are more important. Both missions are usually recalled as failures despite the Australian troops having been extremely successful in their roles during both deployments. Moreover the experiences with intervention in Africa seem to have forever blighted Australian participation in peace missions on that continent.

From site to text : Australian Aborigines and the origin of the family

Missions were not simply sites of modernity, they were also the source of key data for the modernist theories of human progress. The idea that so called “primitive peoples” provided a window to the origins of human institutions seemed axiomatic to nineteenth-century theorists of human society who sought evidence for these ideas from settlers, administrators and particularly missionaries. The 1870s and 1880s were the high point of missionary engagement with study-bound anthropologists, as questionnaires and letters were sent from the centres to the edges of empires. Missionary responses, augmented with settler and explorer observations, became the footnotes in early anthropological texts on “primitive” societies. These analyses were then mined for the foundation texts of the other social sciences in the late nineteenth century. Along with many other scholars, Karl Marx and Friedrich Engels read the anthropology of the period and slotted the findings into their analyses of human society.

Missionary Albert Kruyt and colonial modernity in the Dutch East Indies

Intense debates emerged in the Dutch East Indies during the course of the third decade of the twentieth century concerning the role of missionaries in the development of the Outer Islands of the Indonesian archipelago. Ostensibly concerning “native welfare”, disagreement fundamentally reflected underlying fractures within the Dutch nation, projected through its “colonial mission” concerning the nature of modernity. While the main focus appeared to be a disagreement concerning the goals of mission and government agencies, it would be too simplistic to characterise the debate as one between adherents of a secular versus a religious world view. This paper considers the question of “missions and modernity” in the context of this debate about “native development” in the Dutch East Indies through the prism of the Poso mission in Central Sulawesi, headed by missionary Albert Kruyt, one of the foremost missionaries of his day.

Multi-market industrial organizational economic models for the internationalization process by small and medium enterprise construction design service firms

Small and medium enterprises (SMEs) are critical to strategic initiatives in an economy; however, their contribution to foreign trade is not as significant. SMEs are one of the principal driving forces in economic development. One of the greatest challenges is the internationalization process for longevity rather than seeing the process as initial market entry. The internationalization process research has typically involved four key constructs: market selection, decision to enter, entry modes and factors affecting entry modes. Past research has focused on large manufacturing firms. The export of architectural, engineering and construction (AEC) firms has undergone growth, yet there is still significant opportunity for further growth. The majority of AEC firms are SMEs. Notwithstanding assistance provided through international trade missions, organized export firm support networks and information packages by a burgeoning number of government agencies, there are still perceived barriers to market entry and long-term economic sustainability for SMEs. There are a number of problems faced by SMEs acting in foreign trade. This investigation explores the successful initial internationalization process constructs and identifies unique project-oriented sector characteristics. The study identified similarities and differences between two firms that have been exporting to various localities, including Eastern Europe, Africa, Middle East, UK, Asia and South America, for more than two decades. The similarities and differences were identified within eight major constructs: purpose, firm type, market image and design philosophy, entry mode strategy, institutional arrangement, factors affecting mode of entry, market selection and firm strategy in relation to project selection. The primary reasons for internationalization were associated with the firms' motivations related to growth and financial viability. This article discusses the various internationalization processes and strategies intrinsic to each case study and establishes a detailed set of empirical observations from which to develop further a grounded theoretical model of reflexive capability for the internationalization process. This study contributes to the body of knowledge around the SME AEC design service firm's internationalization process, as a dynamic, evolving and continuously adaptable construct for project-based sectors.

'Mother, teacher, adviser and missionary' : Matilda Ward in North Queensland, 1891–1917

This chapter focuses on Matilda Ward, a missionary at the Presbyterian mission of Mapoon, north Queensland, and the first paid woman missionary to work on an Aboriginal mission. It examines the factors that led to Ward’s employment on the mission, the role that she played in the life of the mission and the consequences of her actions for Indigenous mission residents. While Matilda Ward was unusual for her time, her experience points to broader shifts in missionary practice and attitudes to gender within the Australian churches, particularly through the development of women’s missionary societies.

Creating an Indigenous Christian leadership in Papua

In eastern Papua, Christian missionaries found a social structure unparalleled in most areas of religious expansion in the world: it apparently lacked chiefs and any identifiable leadership. Nearly all the Massim societies of eastern Papua were matrilineal, and land was passed through females. Here, women enjoyed a higher status than elsewhere in what is now Papua New Guinea. By drawing on the records of missionary agents, both European and Polynesian, this paper shows how the Methodist, Anglican and Kwato (London Missionary Society) missions in eastern Papua all encountered difficulty in fostering a cadre of male leaders, but — as became evident after World War II — they experienced greater success in fostering women's leadership.

The politics of Timor-Leste : democratic consolidation after intervention

The Politics of Timor-Leste explores the critical issues facing the Asia-Pacific's youngest nation as it seeks to consolidate a democracy following years of international intervention. The authors study the challenges that have burdened the state since it broke from Indonesia amid the violence of 1999 and formally achieved full independence in 2002. They assess the notable accomplishments of Timor-Leste’s leaders and citizens, and consider the country’s future prospects as international organizations prepare to depart. A close study of Timor-Leste sheds light on ambitious state-building projects that have been initiated, with varying success, across the globe.

Contributors to this volume map the nation’s recent political evolution through studies of its constitutional debates, political parties, and foreign policy responses to powerful neighbors. They address the social and economic conditions that complicate Timor-Leste’s political development, such as gender discrimination, poverty, corruption, and security-sector volatility. The contemporary history of Timor-Leste reflects the experiences of many postcolonial and developing countries that have sought to establish a viable state following conflict and a declaration of independence. This small nation has been the subject of five consecutive UN missions with varying mandates. The Politics of Timor-Leste ought to serve as a key source for comparative postcolonial studies and a guide to future trends in international state-building and assistance.

Defining citizenship for a new nation: Papua New Guinea, 1972–1974

A key part of any process of decolonisation is the need for the emerging nation to determine the rules for citizenship. In Papua New Guinea, what it meant to be a citizen was the first topic that the Constitutional Planning Committee considered when it set about its task to develop a ‘home grown’ constitution in late 1972. The process by which it first comprehended this matter and then involved thousands of Papua New Guineans in their villages, missions and schools in a territory-wide exercise in consultation forms the subject of this paper. The records of the discussions that took place between February and April of 1973 reveal much of how the criteria for membership of the national enterprise came to be established. This case study of defining citizenship in PNG demonstrates the intensive consultation of the local peoples on key issues in nation-building and reveals the high degree of Indigenous agency in the decolonisation process.

The teacher education evolution : the shift from online to mobile learning in curriculum, assessment and delivery

Most teacher education programs have online applications. Increasingly teacher education programs are expanding their distance education applications with mobile learning, or m-learning. Although related to online learning, m-learning focuses on the learning opportunities offered by mobile technologies. Mobile learning is a big step towards providing flexible teacher education; it has brought about a new forum for learning, decreased limitations of learning location, and provided learners with choices about how and when they access learning materials. Universities are finding themselves grappling with how best to utilize mobile technologies for learning, while staying within their educational missions and resources. In this paper the mobile devices used in higher education and the current status of mobile technologies as learning tools at universities are described. The background of approaches and methods which are currently in use are also discussed, plus universities and teacher readiness for this transformation are also reviewed. Affordances and constraints are considered.

Effects of long-term head-down-tilt bed rest and different training regimes on the coagulation system of healthy men

Immobility plus preexisting chronic disease or acute trauma can activate the coagulation system, thus increasing the risk for thromboembolic events. The effects of long-term bed-rest immobility and microgravity on the coagulation system of healthy persons (e.g., during crewed Mars missions) have not yet been studied. The main objective of the second Berlin BedRest Study (BBR2-2) "Coagulation Part" was to investigate adaptations of the hemostatic system during long-term bed rest (60 days) under simulated microgravity (6° head-down-tilt [6°HDT]) and after mobilization in three different volunteer groups (randomly assigned to CTR= inactive control group; RE= resistive exercise only group; and RVE= resistive exercise with whole-body vibration group). In 24 males (aged 21-45 years), before, during, and after long-term bed rest, key parameters of coagulation were measured from venous blood samples: D-dimer (DD), thrombin-antithrombin III complex (TAT), and prothrombin fragment F1 + 2 (PT-F1 + 2). Additionally, modified rotational thrombelastometry (ROTEM (®) ) analysis was performed. Times of exploratory analyses were as follows: baseline data collection 2 days before bed rest (BDC-2); eight different days of 6°HDT bed rest (HDT1-HDT60), and two different days after reambulation (R + 3 and R + 6). We found significant changes in DD, TAT, and PT-F1 + 2 over the total time course, but no consistent effect of physical interventions (RE, RVE) on these parameters. Notably, no parameter reached levels indicative of intravascular thrombin formation. All ROTEM® parameters remained within the normal range and no pathological traces were found. Sixty days of 6°HDT bed rest are not associated with pronounced activation of the coagulation system indicative of intravascular thrombus formation in healthy volunteers independent of the training type during the bed rest.
