An Ethics For Working Up?: Japanese Corporate Scandals And Rethinking Lessons About Fieldwork, Elise Edwards

Elise M. Edwards

Almost forty years after Laura Nader's initial rallying call for anthropologists to “study up,” research on power holders and elite individuals and institutions still constitutes only a small fraction of ethnographic work. In addition, many of the methodological and ethical issues specific to studying up remain under-examined. Most discussions of methodological and ethical dilemmas in anthropology to date have assumed a power differential that favors the anthropologist. What happens when the power vector points in the other direction? Through the retelling of dilemmas faced when dealing with a very powerful and prominent field subject, I set the stage for a …

Effects Of Particle's Off-Axis Position, Shape, Orientation And Entry Position On Resistance Changes Of Micro Coulter Counting Devices, Zhenpeng Qin, Jiang Zhe, Guo-Xiang Wang

Dr. Guo-Xiang Wang

With the recent advance in micro/nano-fabrication technology, micro Coulter counters have been widely used in detecting and characterizing micro- and nanoscale objects. In this paper, the electrical resistance change during translocation of a non-conducting particle through a channel is studied numerically. The numerical results are validated by proven analytical results available in the literature. The effects of particle's off-axis position, shape and orientation, and entry position are studied for particles with a large dynamic range. From the numerical results, a new fitted correlation is proposed that can accurately predict the resistance change caused by off-axis spherical particles regardless of their …

A Novel Mutation Of Cyld In A Chinese Family With Multiple Familial Trichoepithelioma, Z. Ying, H. Ma, Y. Liu, S. Xiao, Y. Wang, Guo-Xiang Wang

Dr. Guo-Xiang Wang

Trichoepithelioma is a benign cutaneous tumour that originates from hair follicles and occurs either as a sporadic non-familial or a multiple-familial type. Recently, several mutations in the cylindromatosis (CYLD) gene have been reported in multiple familial trichoepithelioma (MFT).

Ideas And Collaborative Governance: A Discursive Localism Approach, Neil Bradford

Neil Bradford

In recent years, interest has grown in collaboration in public policy. Responding to the complex issues now playing out in cities, scholars are focusing on localized governance relations that blur boundaries between public, private, and community sectors. This article introduces discursive localism as a framework to understand better collaborative urban governance. It argues that ideas play a pivotal role in motivating collective action, channeling policy resources, and shaping governance relations. Although recent urban-focused accounts of collective action suggest a role for ideas, systematic attention to their normative-philosophical and cognitive-programmatic dimensions reveals how different policy discourses frame incentives and institutions for …

Fan Fiction Metadata Creation And Utilization Within Fan Fiction Archives: Three Primary Models, Shannon Johnson

Shannon F Johnson

Issues related to searchability and ease of access have plagued fan fiction since its inception. This paper discusses the predominate forms of fan-mediated indexing and descriptive metadata, commonly referred to as folksonomy or tagging, and compares the benefits and disadvantages of each model. These models fall into three broad categories: free tagging, controlled vocabulary, and hybrid folksonomy. Each model has distinct advantages and shortcomings related to findability, results filtering, and creative empowerment. Examples for each are provided. Possible ramifications to fan fiction from improved metadata and access are also discussed.

Individual Characteristics And Their Effect On Predicting Mu Rhythm Modulation, Adriane Randolph, Melody Jackson, Saurav Karmakar

Adriane B. Randolph

Brain-computer interfaces (BCIs) offer users with severe motor disabilities a nonmuscular input channel for communication and control but require that users achieve a level of literacy and be able to harness their appropriate electrophysiological responses for effective use of the interface. There is currently no formalized process for determining a user's aptitude for control of various BCIs without testing on an actual system. This study presents how basic information captured about users may be used to predict modulation of mu rhythms, electrical variations in the motor cortex region of the brain that may be used for control of a BCI. …

Developing Soft Skills To Manage User Expectations In It Projects: Knowledge Reuse Among It Project Managers, Stacie Petter, Adriane Randolph

Adriane B. Randolph

This research explores information technology (IT) project managers' reuse of knowledge associated with soft skills when managing user expectations. Through interviews with IT project managers, several themes emerged: novelty of problems, conditions within the organization, types of available knowledge, and methods for reusing knowledge. Within this study, we discovered the need for additional research on how social norms and organizational conditions encourage or inhibit knowledge reuse. Furthermore, we identified a difference in the usefulness of knowledge captured in formal repositories according to levels of project management experience. The findings confirm, extend, and illuminate the current research associated with knowledge reuse …

How To Implement The Electronic Health Record In Undergraduate Nursing Education, Carol Sternberger, Linda Meyer, Tammy Toscos

Carol S Sternberger

Information literacy, evidence-based practice (EBP), and informatics are fundamental to delivering culturally competent, safe patient care. Yet most nursing schools continue to educate students in traditional ways; only a minority integrate high-fidelity simulations, require evidence-based literature to support nursing interventions, identify the five core competencies for healthcare professions delineated by the Institute of Medicine (IOM), and incorporate the electronic health record (EHR) to stimulate critical thinking and decision making. The Health Information Technology Act (2009) requires all healthcare facilities to fully adopt EHRs by 2014. This will change how nurses practice, underscoring the importance of teaching students about informatics and …

The Relation Between Variance And Information Rents In Auctions, Brett Katzman, Julian Reif, Jesse Schwartz

Jesse A. Schwartz

This paper examines the conventional wisdom, expressed in McAfee and McMillan's (1987) widely cited survey paper on auctions, that links increased variance of bidder values to increased information rent. We find that although the conventional wisdom does indeed hold in their (1986) model of a linear contract auction, this relationship is an artifact of that particular model and cannot be generalized. Using Samuelson's (1987) model, which is similar but allows for unobservable costs, we show that increased variance does not always imply increased information rent. Finally, we give the appropriate measure of dispersion (different from variance) that provides the link …

Wage Bargaining Under The National Labor Relations Act, Jesse Schwartz, Quan Wen

Jesse A. Schwartz

Sections 8(a)(3) and 8(a)(5) of the National Labor Relations Act (NLRA) prohibit the management of a firm from unilaterally increasing the wage during contract negotiations without the union's approval. We show how the management can strategically increase the wage during negotiations without violating the NLRA. Increasing the wage during negotiations will upset the union's incentive to strike and decrease the union's bargaining power, thereby shrinking the set of equilibrium contracts in the firm's favor. Indeed, as the union becomes more patient, the set of equilibrium wages converges to the best equilibrium outcome to the firm.

Dominant Strategy Implementation With A Convex Product Space Of Valuations, Katherine Cuff, Sunghoon Hong, Jesse Schwartz, Quan Wen, John Weymark

Jesse A. Schwartz

A necessary and sufficient condition for dominant strategy implementability when preferences are quasilinear is that, for every individual i and every choice of the types of the other individuals, all k-cycles in i's allocation graph have nonnegative length for every integer k ≥ 2. Saks and Yu (Proceedings of the 6th ACM conference on electronic commerce (EC'05), pp 286-293, 2005) have shown that when the number of outcomes is finite and i's valuation type space is convex, nonnegativity of the length of all 2-cycles is sufficient for the nonnegativity of the length of all k-cycles. In this article, it is …

Wage Negotiation Under Good Faith Bargaining, Jesse Schwartz, Quan Wen

Jesse A. Schwartz

We study the wage negotiation model of Haller and Holden (1990) and Fernandez and Glazer (1991) under the "Good Faith Bargaining" (GFB) rule, where a party may not demand more than it has previously demanded. The GFB rule significantly restricts feasible strategies, but at the same time, makes the game non-stationary and the analysis complicated. We introduce a state-dependent backward induction that generalizes Shaked and Sutton (1984) to characterize the equilibrium payoffs. We find that the GFB rule eliminates the union's credibility to strike. Without the strikes, the union's strategic opportunities during disagreement disappear, so that there is a unique …

It Project Managers' Perceptions And Use Of Virtual Team Technologies, Catherine Beise, Fred Niederman, Herbert Mattord

Herbert J. Mattord

This paper presents the results of a case study pertaining to the use of information and communication media to support a range of project management tasks. A variety of electronic communication tools have evolved to support collaborative work and virtual teams. Few of these tools have focused specifically on the needs of project managers. In an effort to learn how practicing IT project managers employ these tools, data were collected at a North American Fortune 500 industrial company via interviews with IT project managers regarding their use and perceptions of electronic media within the context of their work on project …

Optically Stimulated Luminescence (Osl) Dating Of Perenially Frozen Deposits In North-Central Siberia: Osl Characteristics Of Quartz Grains And Methodological Considerations Regarding Their Suitability For Dating, Lee Arnold, Richard Roberts

Richard G Roberts

Optically stimulated luminescence (OSL) dating of coarse-grained quartz is increasingly being used as the main chronological tool in late Quaternary palaeoenvironmental reconstructions of Siberia. However, relatively little information has been published on the suitability of OSL dating for the various types of perennially frozen sediments found in this region. Here we provide a systematic examination of the quartz luminescence characteristics of 21 perennially frozen samples from the Taimyr Peninsula and adjacent coastal lowlands of north-central Siberia, and discuss their implications for the reliability of single-grain and multi-grain OSL chronologies in such contexts. The results of this study suggest that the …

Development Of The Sar Tt-Osl Procedure For Dating Middle Pleistocene Dune And Shallow Marine Deposits Along The Southern Cape Coast Of South Africa, Zenobia Jacobs, Richard Roberts, Terry Lachlan, Panagiotis Karkanas, Curtis Marean, David Roberts

Richard G Roberts

Optically stimulated luminescence (OSL) dating is now commonly used to estimate the depositional age of Quaternary landforms along the southern Cape coast of South Africa. Due to the early onset of dose saturation in the quartz-rich sediments from this region, determining the age of deposits much older than the last three glacio-eustatic sea-level high stands has been a challenge. In this study, we explored the feasibility of using the thermally-transferred OSL (TT-OSL) dating method to obtain ages for aeolian and shallow marine deposits at three different localities that hold promise to further illuminate the long and complex Late Quaternary sea-level …

Dirt, Dates And Dna:Osl And Radiocarbon Chronologies Of Perenially Frozen Sediments In Siberia, And Their Implications For Sedimentary Ancient Dna Studies, Lee Arnold, Richard Roberts, Ross Macphee, James Haile, Fiona Brock, Per Moller, Duane Froese, Alexei Tikhonov, Allan Chivas, M. Thomas Gilbert, Eske Willerslev

Richard G Roberts

The sedimentary ancient DNA (sedaDNA) technique offers a potentially invaluable means of investigating species evolution and extinction dynamics in high-latitude environments. An implicit assumption of the sedaDNA approach is that the extracted DNA is autochthonous with the host deposit and that it has not been physically transported from older source deposits or reworked within the sedimentary profile by postdepositional mixing. In this paper we investigate whether these fundamental conditions are upheld at seven perennially frozen wetland sites across the Taimyr Peninsula and coastal lowlands of north-central Siberia. Optically stimulated luminescence (OSL) and radiocarbon (14C) dating are used to constrain the …

Late Acheulean Hominins At The Marine Isotope Stage 6/5e Transition In North-Central India, Michael Haslam, Richard Roberts, Ceri Shipton, J Pal, Jacqueline Fenwick, Peter Ditchfield, Nicole Boivin, A Dubey, M Gupta, Michael Petraglia

Richard G Roberts

Single-grain optically stimulated luminescence dating was applied to Late Quaternary sediments at two sites in the Middle Son Valley, Madhya Pradesh, India. Designated Bamburi 1 and Patpara, thesse sites contain Late Acheulean stone tool assemblages, which we associate with non-modern hominins. Age determinations of 140-120. ka place the formation of these sites at around the Marine Oxygen Isotope Stage 6-5 transition, placing them among the youngest Acheulean sites in the world. We present here the geochronology and sedimentological setting of these sites, and consider potential implications of Late Pleistocene archaic habitation in north-central India for the initial dispersal of modern …

Taxing Our Future: The Burden Of The Australian Superannuation Taxation System, Corinne Cortese, John Glynn

John J Glynn

This study provides an examination of the Australian superannuation system and demonstrates the onerous taxation burden applied to Australian superannuation contributions and earnings. Using Canada, New Zealand, the UK, and the USA as a basis for comparison, the superannuation schemes and supporting taxation systems of each of the five countries of the study are reviewed. A scenario is developed and applied that demonstrates the inequity of the Australian system relative to comparable nations. Given concerns about the ageing population, this research supports calls for further reforms to the taxation of superannuation in Australia, which highlight the need to make superannuation …

Sme Innovation Within The Australian Wine Industry: A Cluster Analysis, David Aylward, John Glynn

John J Glynn

This paper assesses core innovation activity among SMEs within different levels of cluster development. The aim of the paper, using empirical data from the Australian wine industry, is to demonstrate that innovation levels and activity intensify as an industry cluster develops. By dividing wine clusters into ‘innovative’ (highly developed) and ‘organised’ (less developed) models, the paper uses selected core indicators of innovation activity to explore levels of integration within each model. This integration is examined in the context of Porter’s theory of ‘competitive advantage’, with implications for SMEs in particular, and lessons for industry clusters in general.

On The Step Response Of The Dct, Jim Andrew, Philip Ogunbona

Professor Philip Ogunbona

We show that the discrete cosine transform (DCT) is the best orthogonal transform, in terms of energy packing efficiency, for coding input steps of uniformly distributed random phase. Over sufficiently small block sizes, edges in an image can be modeled as such step inputs. This characteristic of the DCT, coupled with its high energy packing efficiency for highly correlated data, helps explain the impressive performance of the DCT for image compression.

On The Combination Of Local Texture And Global Structure For Food Classification, Zhimin Zong, Duc Thanh Nguyen, Philip Ogunbona, Wanqing Li

Professor Philip Ogunbona

This paper proposes a food image classification method using local textural patterns and their global structure to describe the food image. In this paper, a visual codebook of local textural patterns is created by employing Scale Invariant Feature Transformation (SIFT) interest point detector with the Local Binary Pattern (LBP) feature. In addition to describing the food image using local texture, the global structure of the food object is represented as the spatial distribution of the local textural structures and encoded using shape context. We evaluated the proposed method on the Pittsburgh Fast-Food Image (PFI) dataset. Experimental results showed that the …

Should Methionine Be Added To Every Paracetamol Tablet?, Alison Jones, P Hayes, A Proudfoot, J Vale, L Prescott

Alison L Jones

Paracetamol is commonly used for self poisoning, and the costs of treating the resulting liver failure in the few who develop it are high. The morbidity could be avoided by adding methionine to paracetamol tablets, but this would mean that the millions of people who take paracetamol responsibly would have to take methionine unnecessarily. Alison Jones and colleagues and Edward Krenzelok debate the issue.

Prolonged N-Acetylcysteine Therapy In Late Acetaminophen Poisoning Associated With Acute Liver Failure--A Need To Be More Cautious?, T Nimmi, C Athuraliya, Alison Jones

Alison L Jones

Since the 1970s, N-acetylcysteine (NAC) has shown proven efficacy as an antidote for acetaminophen (APAP) poisoning and APAP-induced liver failure for early presenters. The current evidence of benefits of NAC for late presenters is controversial because of the poor understanding of the mechanism of late toxicity. In the previous issue of Critical Care, Yang and colleagues use a mouse model to demonstrate that NAC in doses similar to those used therapeutically to treat APAP poisoning in humans impairs liver regenerative capacity and that the effect is more pronounced when administered for a longer duration. Studies based on cell cultures support …
