Birds and Kastom Banyans of South Pentecost: Kastom in AntiColonial Struggle

In the traditionalist villages of south Pentecost, kastom has long been a bulwark against European influences, both Christian and secular. However, their retention of the famous gol land dive ritual has brought the south Pentecost people under pressure from tourism, whose great allure masks the risks of a rise of kastom as commodity, packaged for sale, and of the erosion of kasfom's centrality as living practice. Pressures to conform to a pure kastom (i.e. unadulterated by any non-indigenous elements) distort the realities of a dynamic kastom that has long incorporated useful elements of alien material culture into everyday living.     

The geo‐classifications of colonial statelessness: The anthropology of Kastom,land and citizenship in the decolonisation of Vanuatu

Anthropological accounts of Vanuatu's independence have emphasised both the materiality of land alienation and the importance of kastom (custom) as a symbol of cultural practice, political resistance and national unity in accounts of decolonisation and postcolonial nation‐making. For 74 years indigenous ni‐Vanuatu were stateless and lacked all forms of citizenship and nationality in the Anglo‐French Condominium of the New Hebrides (1906–1980). This article situates anthropological accounts of land, kastom and the state in Vanuatu's transition to independence in relation to statelessness, citizenship and hierarchies of ethnographic authenticity within the geo‐classificatory frameworks of colonial rule established by the condominium. The embodiment of citizenship and demands to end the cumulative humiliations of statelessness that ni‐Vanuatu experienced in the condominium illuminate both tensions and continuities in idealist and materialist accounts of Melanesian nationalisms evident in kastom and land as they were mediated by the emancipatory claims and promises of postcolonial citizenship.     

Kastom and Anticolonialism on Malaita: “Culture” as Political Symbol

Most Melanesians invoking ideologies of kastom have, in becoming Christianized and partly Westernized, hearkened back to ways now lost or abandoned. But the Kwaio of Malaita are preoccupied with kastom, while traditional religion, social organization and exchange still prevail. Why and how? The Kwaio are compared with Kwara'ae and other Malaita peoples concerned with kastom - many Christianized, others clinging to old ways.     

Leftamap Kastom: The Political History of Tradition on Tanna,Vanuatu

The history of evaluation and definition of kastom on Tanna exemplifies its utility in attempts to reformulate social groups by reworking group charter myths, and its manipulation in political events by rival organizations seeking a customary legitimacy. On Tanna, where political prestige and authority depend heavily on the control and communication of knowledge, kastom knowledge as political capital enjoys enhanced status following the rehabilitation of kastom at the national level. Pro-kastom groups on Tanna, such as the John Frum cultists, have benefited from this positive evaluation of kastom, but some anomalies and sources of conflict remain in the fusion of kastom with Christianity and modernism. People argue over their respective domains and the fields of their application. Alternate definitions and uses of kastom invoke disunity and political competition at the local level, in contrast to national emphases on kastom as symbol of political unity and shared identity.     

Kastom,Christianity and the First Ancestor of the Kwara'ae of Malaita

The Kwara'ae of Malaita, now mainly Christian and enmeshed in the cash economy, invoke an ideology of kastom, reconciling biblical and ancestral origins, validating land claims, and legitimizing as traditional postcolonial political hierarchies built on the old ritual svstem. The political uses of kastom ideology in contemporary Kwara'ae, and their historical roots, are explored.     

Provincialising Lakatoro: Orienting sociality through a state institution in Vanuatu

Focusing on Lakatoro, a provincial centre in Vanuatu, this article explores the ways in which a state institution may allow kastom‐based sociality to proceed for the local population. Rather than considering kastom and the state as necessarily separate, it is demonstrated that the institutions of the state can provide the objective forms needed for kastom to exist in urban space. The article discusses three ways in which this happened—through a staff handbook, daily prayer meetings, and a court case—arguing that ‘the province’s’ polyvalence provided a means by which Lakatoro could be experienced as a place. And that this, in turn, provided a way in which the local population could understand the town to be imbued with appropriate sociality, as measured by kastom.     

The Invention of Convention

The traditional past of the people of South-West Bay, Malekula, featured a great deal of cultural borrowing. Like most Christians in Vanuatu, their negative attitude to a 'pagan' past has been changed into one of positive interest by the recent national emphasis on kastorn. Their older perception of kastorn as commodity - knowledge, rituals, objects, etc. to be bought, sold or exchanged at will - has been supplemented by the more wide- spread notion of kastom as a stable body of traditions, unshared as well as shared. The validatory potential of kastorn is being realized as people re-evaluate and reinvent their past, exploiting lacunae in customary knowledge by imaginative citation of the written ethnographic word. Contemporary needs are apparently more effectively satisfied by reference to fixed truths rather than to fluid and dynamic representations of culture.     

VISUALIZATION OF THE BILIARY TRACT—Preoperative,Operative and Postoperative Radiologic Investigation

Modern operative treatment of diseases of the bile passages requires the use of x-ray visualization of the biliary tract before, after and during operation. Nearly every surgeon uses x-ray study of the biliary tract before operation and it is widespread practice to carry out such study after operations in which a tube has been placed in the bile passages. However, there is a remarkable aversion to operative cholangiography.The usual reasons for avoiding operative cholangiography are unfamiliarity, inertia, concern over complications of the technique, and the feeling that it is unnecessary or wasteful of surgeon''s time and patient''s money. Yet the results of operative cholangiograms compare favorably with those obtained with the more customary x-ray studies of the bile ducts carried out after operation, at a time when the information gained is much less valuable in avoiding additional operations and in contributing to a smooth and rapid convalescence.     

The Social Life of Rights: ‘Gender Antagonism’, Modernity and Raet in Vanuatu

In the northern Vanuatu town of Luganville a small group of men have responded to social and legal changes engendered by women's rights activists by forming a male support group called ‘Violence Against Men’. Members of this ‘backlash’ movement argue that the insidious promotion of Western‐style ‘women's rights’ is leading to discrimination against men in divorce proceedings, child custody battles, and in domestic violence and rape cases. They directly oppose recent and ongoing legal changes aimed at protecting women from domestic violence, such as Domestic Violence Protection Court Orders, and the repeatedly tabled (but long‐delayed) ‘Family Protection Bill’. Such interventions, they argue, undermine Vanuatu's ‘natural’kastom and Christian patriarchal gender order and, in doing so, pose a serious threat to the socio‐economic productivity of the nation‐state. For other men, however, rather than opposing women's rights activism, such challenges have raised questions about how men might successfully negotiate their identities in ways that are sensitive to contemporary issues of gender equality without undermining existing paradigms. Thus, this paper addresses the value accorded to universalism and relativism in gender activism in Vanuatu, and especially in terms of the linked discourses of kastom, church and modernity. It therefore explores gender relations in terms of the contemporary entanglement of indigenous and exogenous epistemologies, and in doing so argues that the contextual analysis of ‘rights’ should consider the specific historical, political and socio‐cultural circumstances in which they are put to use.     

Systolic Peak Detection in Acceleration Photoplethysmograms Measured from Emergency Responders in Tropical Conditions

Photoplethysmogram (PPG) monitoring is not only essential for critically ill patients in hospitals or at home, but also for those undergoing exercise testing. However, processing PPG signals measured after exercise is challenging, especially if the environment is hot and humid. In this paper, we propose a novel algorithm that can detect systolic peaks under challenging conditions, as in the case of emergency responders in tropical conditions. Accurate systolic-peak detection is an important first step for the analysis of heart rate variability. Algorithms based on local maxima-minima, first-derivative, and slope sum are evaluated, and a new algorithm is introduced to improve the detection rate. With 40 healthy subjects, the new algorithm demonstrates the highest overall detection accuracy (99.84% sensitivity, 99.89% positive predictivity). Existing algorithms, such as Billauer''s, Li''s and Zong''s, have comparable although lower accuracy. However, the proposed algorithm presents an advantage for real-time applications by avoiding human intervention in threshold determination. For best performance, we show that a combination of two event-related moving averages with an offset threshold has an advantage in detecting systolic peaks, even in heat-stressed PPG signals.     

Melanesian Kastom and Its Transformations

Editorial Board Note: In 2006, the Discipline Group of Anthropology and Sociology at The University of Western Australia hosted a symposium, ‘Anthropology in the West: 1956–2006’, to celebrate the 50th anniversary of the founding of the then Department of Anthropology by the late Ronald Berndt and his wife, Catherine, whose contributions to anthropology were a major focus of the symposium. Symposium participants also documented contributions made by UWA staff and students from Anthropology and Sociology within and beyond Australian social science. A notable theoretical focus on kastom in the work of Robert Tonkinson, who in 1984 succeeded Professor Berndt in the Departmental Chair, was the topic of Lamont Lindstrom's paper, published here in a fuller, revised and fully refereed version. We intend to publish further papers from the symposium in later issues of Anthropological Forum.

If Ronald and Catherine Berndt are ancestral spirits haunting Anthropology and Sociology at The University of Western Australia some 50 years after the founding of the Department of Anthropology, their student, Bob Tonkinson, still happily with us, is their intellectual descendant and institutional heir. As in the case of the Berndts, issues relating to social change, religion and values, and, in particular, the politics of tradition have loomed large in Tonkinson's career. I trace, in this retrospective essay, the rise to prominence of an anthropology of Melanesian tradition and, more specifically, Tonkinson's contribution, notably his analyses of tradition's ‘symbiotic’ relations with Christianity, its identity functions, its local versus its national significance, and its relations with evolving anthropological theories of culture in a shrinking world. Tonkinson's Vanuatu research, which began among Ambrym Island emigrants, has spanned, over the past forty years or so, many notable transformations: from New Hebrides to Vanuatu; from modernisation theory to world systems and globalisation; and from tradition to kastom.     

Reflecting on Loss in Papua New Guinea

This article takes up the conundrum of conducting anthropological fieldwork with people who claim that they have ‘lost their culture,’ as is the case with Suau people in the Massim region of Papua New Guinea. But rather than claiming culture loss as a process of dispossession, Suau claim it as a consequence of their own attempts to engage with colonial interests. Suau appear to have responded to missionization and their close proximity to the colonial-era capital by jettisoning many of the practices characteristic of Massim societies, now identified as ‘kastom.’ The rejection of kastom in order to facilitate their relations with Europeans during colonialism, followed by the mourning for kastom after independence, both invite consideration of a kind of reflexivity that requires action based on the presumed perspective of another.     

Function of the SIRT3 mitochondrial deacetylase in cellular physiology,cancer, and neurodegenerative disease

In mammals, seven members of the sirtuin protein family known as class III histone deacetylase have been identified for their characteristic features. These distinguished characteristics include the tissues where they are distributed or located, enzymatic activities, molecular functions, and involvement in diseases. Among the sirtuin members, SIRT3 has received much attention for its role in cancer genetics, aging, neurodegenerative disease, and stress resistance. SIRT3 controls energy demand during stress conditions such as fasting and exercise as well as metabolism through the deacetylation and acetylation of mitochondrial enzymes. SIRT3 is well known for its ability to eliminate reactive oxygen species and to prevent the development of cancerous cells or apoptosis. This review article provides a comprehensive review on numerous (noteworthy) molecular functions of SIRT3 and its effect on cancer cells and various diseases including Huntington's disease, amyotrophic lateral sclerosis, and Alzheimer's disease.     

The Promise and Peril of the Pharmacological Enhancer Modafinil

The neuro‐enhancement Modafinil promises to dramatically increase users' waking hours without much sacrifice to clarity of thought and without serious side effects (inducing addiction). For Modafinil to be advantageous, its usage must enable access to goods that themselves improve the quality of one's life. I draw attention to a variety of conditions that must be met for an experience, activity or object to improve the quality of one's life, such as positional, relational, and saturation conditions, as well as it's being good for its own sake. I discuss and describe the contexts in which widespread usage (legal or not) of Modafinil would undermine these conditions being met, and thus users would fail to significantly improve the quality of their lives and would in fact potentially make both themselves and nonusers worse off in important respects thus far overlooked by critics. In the right contexts, where free time is protected and prolonged, Modafinil does have a variety of potential benefits including, most interestingly, a distinctive form of agency possible only in free time. The potential disadvantages and advantages highlighted in this article are relevant not only to public institutions deciding whether to legalize Modafinil's use as an enhancement but also to individuals deciding whether to use it illegally, as well as to the questions of how and whether to alter key features of one's context (e.g. regulating work hours or extending social services) rather than, or in addition, to regulating the use of enhancement drugs such as Modafinil.     

Cost-benefit analysis.

Cost-benefit analysis is probably the most comprehensive method of economic evaluation available and it can be applied in two ways. The human capital approach means that the value of people''s contributions is linked to what they are paid. The approach based on individuals'' observed or stated preference means that their personal valuations are placed on an activity by assessing how much money they are prepared to accept for an increased risk or to pay for a particular service. Each method has its disadvantages and the most successful that has been devised so far is the "willingness to pay" (stated preference) approach, though the response to this is to a large extent dependent on the income of the person being questioned. There are still problems with its application, however, so its usefulness is limited.     

The first crystal structures of RNA–PNA duplexes and a PNA-PNA duplex containing mismatches—toward anti-sense therapy against TREDs

PNA is a promising molecule for antisense therapy of trinucleotide repeat disorders. We present the first crystal structures of RNA–PNA duplexes. They contain CUG repeats, relevant to myotonic dystrophy type I, and CAG repeats associated with poly-glutamine diseases. We also report the first PNA–PNA duplex containing mismatches. A comparison of the PNA homoduplex and the PNA–RNA heteroduplexes reveals PNA''s intrinsic structural properties, shedding light on its reported sequence selectivity or intolerance of mismatches when it interacts with nucleic acids. PNA has a much lower helical twist than RNA and the resulting duplex has an intermediate conformation. PNA retains its overall conformation while locally there is much disorder, especially peptide bond flipping. In addition to the Watson–Crick pairing, the structures contain interesting interactions between the RNA''s phosphate groups and the Π electrons of the peptide bonds in PNA.     

Rh immunization in Manitoba: progress in prevention and management.

For two decades the perinatal mortality caused by erythroblastosis has been decreasing in Manitoba. The improved management of Rh-immunized pregnancies has lowered the death rate among affected infants from 10.8% to 3.4%, while the prevention of Rh immunization has reduced its incidence from 9.1 to 2.2 per 1000 total births. In its first 6 years and 8 months Manitoba''s antenatal prophylaxis program, in which immunoglobulin is administered to Rh-negative women at 28 weeks'' gestation, reduced the incidence of Rh immunization during pregnancy by 93%. In combination with post-abortion and postpartum prophylaxis the antenatal treatment has provided a protection rate of 98.6% among primigravidas at risk. Further improvements are expected.     

Darwin and palaeontology: a re-evaluation of his interpretation of the fossil record

Charles Darwin's empirical research in palaeontology, especially on fossil invertebrates, has been relatively neglected as a source of insight into his thinking, other than to note that he viewed the fossil record as very incomplete. During the Beagle voyage, Darwin gained extensive experience with a wide diversity of fossil taxa, and he thought deeply about the nature of the fossil record. That record was, for him, a major source of evidence for large-scale transmutation, but much less so for natural selection or single lineages. Darwin's interpretation of the fossil record has been criticised for its focus on incompleteness, but the record as he knew it was extremely incomplete. He was compelled to address this in arguing for descent with modification, which was likely his primary goal. Darwin's gradualism has been both misrepresented and exaggerated, and has distracted us from the importance of the fossil record in his thinking, which should be viewed in the context of the multiple, sometimes competing demands of the multifaceted argument he presented in the Origin of Species.     

The consumption of ritual and the changing values of filial piety in ancestor worship

Ancestor worship is regarded as the key element of the Han people's belief system across most of China. However, the rituals pertaining to death, such as in funerals and annual ancestor worship, vary from place to place. For decades, the state has made tremendous efforts to reform and standardise funerals consistent with its path to modernization by insisting on more socialist practices rather than those that are perceived as ‘superstitious’ and ‘irrational’, such as burning paper and incense or performing rituals. I argue that despite regulating the use of funeral materials or memorial types, the state has failed to reform the essence of death rituals, that is, the duty of filial piety and people's conception of the afterlife. In addition, funerals and other rituals related to death contribute to individual's social reputation.     

People Bouncing on Trampolines: Dramatic Energy Transfer,a Table-Top Demonstration,Complex Dynamics and a Zero Sum Game

Jumping on trampolines is a popular backyard recreation. In some trampoline games (e.g., “seat drop war”), when two people land on the trampoline with only a small time-lag, one person bounces much higher than the other, as if energy has been transferred from one to the other. First, we illustrate this energy-transfer in a table-top demonstration, consisting of two balls dropped onto a mini-trampoline, landing almost simultaneously, sometimes resulting in one ball bouncing much higher than the other. Next, using a simple mathematical model of two masses bouncing passively on a massless trampoline with no dissipation, we show that with specific landing conditions, it is possible to transfer all the kinetic energy of one mass to the other through the trampoline – in a single bounce. For human-like parameters, starting with equal energy, the energy transfer is maximal when one person lands approximately when the other is at the bottom of her bounce. The energy transfer persists even for very stiff surfaces. The energy-conservative mathematical model exhibits complex non-periodic long-term motions. To complement this passive bouncing model, we also performed a game-theoretic analysis, appropriate when both players are acting strategically to steal the other player''s energy. We consider a zero-sum game in which each player''s goal is to gain the other player''s kinetic energy during a single bounce, by extending her leg during flight. For high initial energy and a symmetric situation, the best strategy for both subjects (minimax strategy and Nash equilibrium) is to use the shortest available leg length and not extend their legs. On the other hand, an asymmetry in initial heights allows the player with more energy to gain even more energy in the next bounce. Thus synchronous bouncing unstable is unstable both for passive bouncing and when leg lengths are controlled as in game-theoretic equilibria.
