Outside the Club: New Zealand's economic growth, 1870-1993

Recent tests of the Convergence Hypothesis, or the tendency for per capita income levels to narrow over time, have included a time-series testing approach (see Bernard & Durlauf, 1995, 1996; Oxley & Greasley, 1995, Greasley & Oxley, 1997, 1998a). Results have been mixed, with Bernard & Durlauf finding no evidence of convergence whereas Oxley & Greasley find evidence of two small convergence clubs. This paper adds to the debate by considering a newly created annual per capita income series for New Zealand, 1870-1993. The results show that the series is integrated of order 1, I(1), and neither a single break nor joint breaks overturn the null of a unit root. Combined with results from Greasley & Oxley (1998a, 1998b), this property of New Zealand data is incompatible with her belonging to a UK/Australia convergence club, or converging towards either of the North American economies. New Zealand per capita income growth is idiosyncratic, diverging below the growth rates of traditional trading partners. A conjunction of small size and insular economic policies distinguishes New Zealand's economic development.
Differences between perceived usefulness of social media and institutional channels by undergraduate students

Purpose This research aims to compare the preference of social media sites and institutional communication channels of a higher education institution by confronting elements that form perceived usefulness and user satisfaction with the system. Social media technologies are a part of the routine of the modern society in many diverse ways, including the support and even substitution of software designed specifically for knowledge acquisition and sharing. If students do not see value in the use of virtual learning environments and learning platforms, such tools might be prone to obsolescence as well. Design/methodology/approach The study was applied in a Brazilian public university located in a major city near Sao Paulo. The paper shows the results of the analysis of a survey with 108 answers, testing a model based on the information system success and on the technology acceptance model. The perceived usefulness of information technology is also subject to test through a Student t-test. Findings The paper shows that students perceive more value when using social media technologies to perform academic activities than in information systems provided by the university, mainly owing to the ease of use of the former. Service quality does not present a strong role as an antecedent variable in any case. Practical implications Students do not expect or do not see value in technical support during their general experience or usefulness for any of the analysed technologies. Thus, higher education institutions should focus their initiatives in providing availability, information quality and usability for institutional channels or, if they choose to do so, social media sites as well. Originality/value This study contributes to educational institutions by attaining better use of available IT tools for academic purposes. Previous studies looked for monitored or institutionalized use of social media tools in an educational context, but there was no in-depth analysis of spontaneous use by students to perform academic tasks.
Statistical thinking and its role for industrial engineers and managers in the 21st century

Purpose – The purpose of this paper is to demonstrate the vital linkage between six sigma and statistical thinking. The paper also explains the key characteristics required for statistical thinking and some of the common barriers in the implementation of the key principles of statistical thinking. Design/methodology/approach – The objectives of the paper have been achieved in several ways. The paper provides the key principles of statistical thinking and then discusses the possible reasons for lack of statistical thinking in modern organizations. The paper then illustrates the linkage between the statistical principles and six sigma. The tools and techniques of six sigma used within statistical thinking are also highlighted in the paper. Findings – The key findings of this work include the relationship between the two key powerful methodologies: six sigma and statistical thinking, reasons for lack of applications of statistical thinking in organizations, the future role of managers and engineers in companies with regard to statistical thinking era and the commonalities in the application of tools and techniques between these two methodologies. Research limitations/implications – The paper needs more justification through surveys and case examples and this will be the future step of this study. In fact, one of the co-authors is currently conducting a survey in the UK organizations to investigate the relationship between statistical thinking and six sigma. Practical implications – The paper is very practical in nature and it does yield a great value to those people who are currently embarking on six sigma program, especially at senior manager and executive levels. Originality/value – Very little is published in the field of statistical thinking in the UK academic world. In fact, there is a cognitive gap in this field and this paper certainly forms a good platform for further research that will enable to bridge the gap.
Data detection and pattern recognition on FMS control charts

The quality control system in the flexible manufacturing system (FMS) is analyzed. A simple and practical construction of quality control system is introduced. The pattern recognition of the quality control charts based on neural network is presented. The trained neural network can not only recognize six basic patterns of the quality control charts, but also recognize the hybrid pattern composed of two basic patterns. At last, the simulation result is given.
Recruitment Practices in the Private Sector: Results from a National Survey of Employers

This article reports on the results of a survey conducted in 1996 by AGB McNair of recruitment practices within Australian firms. The responding sample numbered 1448 and is representative of all non-government business establishments which had recruited to fill a vacancy at some time during the previous 12-month period and whose employees were mainly non-professional. The article highlights the relative importance of different recruitment methods, how the incidence of their use varies with both the occupation category of the vacancy and establishment size, and the very different roles played by the public employment service provider (i.e., the CES) and private employment agencies in the recruitment process.
Persistent and Nonpersistent Error Optimization for STT-RAM Cell Design

Rapidly increasing demands for memory capacity and severe technical scaling challenges of conventional memory technologies motivated recent investments on next-generation nonvolatile memory technologies. As a promising candidate, spin-transfer torque random access memory (STT-RAM) has demonstrated many attractive properties, such as nanosecond access time, high integration density, nonvolatility, and excellent CMOS integration compatibility. However, similar to all other nano-devices, the performance and reliability of STT-RAM cells are greatly affected by process variations, device operating uncertainties, and environmental fluctuations. As a result, the read and write operations of STT-RAM demonstrate some variabilities and errors. In this paper, we systematically analyze the impacts of CMOS and magnetic tunneling junction (MTJ) process variations, MTJ resistance switching randomness that are induced by intrinsic thermal fluctuations, and working temperature changes on STT-RAM cell designs. The STT-RAM cell reliability issues in both read and write operations are first investigated. A combined circuit and magnetic simulation platform is then established to quantitatively study the persistent and nonpersistent errors in STT-RAM cell operations. Our analysis proved the importance of a full statistical design method in STT-RAM designs for design pessimism minimization.

Compensation of discrete contact state errors in regrasping experiments with the TUM-hand

We present an approach to compensate for discrete contact state errors in regrasping tasks with multi-fingered robotic hands. An adaptation of reference trajectories connected with a hybrid discrete continuous control architecture allows stable grasps even if moving fingers cannot contact at the desired position on a grasped object. We propose a robust control setup that allows multiple regrasping tasks of objects to be performed using this compensation strategy and contact force optimization. Experimental results with the hydraulic robotic hand of the TUM verify the proposed approach and illustrate the increase in robustness for multi-fingered manipulation.
Is There a Gradient of Mortality Risk among Men with Low Cardiorespiratory Fitness?

PURPOSE A low level of cardiorespiratory fitness (CRF) is a strong and independent predictor of all-cause mortality in men; however, it is unknown whether a gradient of mortality risk exists within the lowest CRF category. METHODS A total of 6251 apparently healthy men (mean age, 48.7 ± 6.3 yr) completed a comprehensive baseline clinical examination, including a maximal treadmill exercise test at Cooper Clinic between 1971 and 2006. In accord with previous studies using this cohort, low CRF was defined as a treadmill time in the first quintile within each age category of 40-49, 50-59, and 60-69 yr. The low CRF cohort was then grouped by tertiles (low/low, LL; mid/low, ML; and high/low, HL) using the same age categories. RESULTS After a mean follow-up period of 19.1 ± 10.4 yr, 1259 deaths occurred. Adjusted all-cause mortality rates were 57.0, 31.1, and 34.4 deaths per 10,000 man-years across LL, ML, and HL CRF categories for the 40- to 49-yr-old age group (P trend = 0.007). Similar trends were seen across low CRF categories for the 50- to 59-yr-old and 60- to 69-yr-old age groups (P trend = 0.02 and 0.09, respectively). When using treadmill time as a continuous variable, each 1-min increment in treadmill time was associated with a 9%, 11%, and 15% reduction in risk of all-cause mortality among low-CRF men in the 40-49, 50-59, and 60-69 age groups, respectively. CONCLUSIONS An inverse trend in all-cause mortality exists among men across LL, ML, and HL CRF groups. Although all low-fit men should be targeted for physical activity intervention, it is especially important to target the LL CRF group.
HIV in the tropics: staging in the resource-limited setting

Purpose of review In 2010, the WHO updated HIV treatment guidelines for adults and children, expanding the eligibility of HIV-infected individuals for antiretroviral therapy (ART) on the basis of immunological staging. We discuss the barriers to HIV staging in under-resourced settings. Recent findings In industrialized countries, HIV-infected patients are immunologically staged using CD4 lymphocyte counts measured using flow cytometry, but reliable and timely CD4 testing is still not readily available for all patients in many poorly resourced countries. Often CD4 testing is only available in central hospitals and clinics and depends upon availability of reagents. This leaves clinical staging as the standard of care in many places. Significant discrepancies exist between clinical and immunologic staging. Lack of immunologic staging can lead to delayed or inappropriate initiation of ART, increased attrition before ART, and overall poorer outcomes as patients often initiate ART at lower CD4 cell count baselines. This has led to intensive efforts to develop cost-effective laboratory testing, particularly for accurate low-cost CD4 testing. Summary Simplified, low-cost alternatives for immunologic staging are vital to continued scale up of ART programs globally. Point-of-care CD4 testing in particular has shown promise in decreasing attrition rates before ART and improving overall mortality in resource-limited settings.
Gamma Interferon Is a Major Suppressive Factor Produced by Activated Human Peripheral Blood Lymphocytes That Is Able To Inhibit Foamy Virus-Induced Cytopathic Effects

ABSTRACT The activation of human peripheral blood lymphocytes by mitogens or by triggering the T-cell receptor with anti-CD3 antibodies leads to the production of a potent soluble inhibitory activity against foamy virus-induced cytopathic effects in vitro. The inhibitory activity acts in a species-specific manner. As a consequence, the isolation of foamy viruses from blood lymphocytes of infected humans is accelerated in a heterologous coculture system. Antibodies against gamma interferon (IFN-γ) are able to suppress most of the inhibitory activity, suggesting that IFN-γ is the dominant component.
Toward a Marxist Theory of the Labor Process: Braverman and Beyond

IT is one of the interesting paradoxes in the history of Marxism, that Marx’s analysis of the labor process, as formulated in Capital, has remained largely unchallenged and undeveloped. Whereas there have been debates over the reproduction schema in volume two of Capital and over the falling rate of profit of volume three, Marxists have taken volume one for granted. Harry Braverman, whose Labor and monopoly Capital reflects and now instigates a resurgence of interest in Marxist theories of the labor process, writes: &dquo;. the extraordinary fact is that Marxists have added little to his body of work in this respect. Neither the changes in productive processes throughout this century of capitalism and monopoly capitalism, nor the changes in the occupational structure of the working population have been subjected to
Network embeddedness: a qualitative study of small technology-based firms

The value of cooperation is recognised as an integral part of small technology-based firms? (STBFs) success; however, there is a lack of research regarding the importance of network embeddedness for these firms. The objective of this study is to overcome this void by applying the systemic evolution model (Yli-Renko and Autio, 1998). Therefore, we performed multiple exploratory case studies in three Portuguese STBFs. We found that the firms have achieved different levels of embeddedness, which is linked with their growth level. As an important driver for network embeddedness, we found the existence of patents. We deduct that the STBFs? future as disseminators of technology will continue to depend on cooperation networks.
Voluntary Incentive Design for Endangered Species Protection

Herein we examine the theory and practical limits of designing a voluntary incentive scheme to protect endangered species on private land. We consider both an ex-ante scheme, in which a contract to the landholder depends only on what the landholder reports, and an ex-post scheme, in which a contract to the landholder depends on reports from all landowners. Except in special cases, the ex-ante scheme never implements the full information allocation, and can actually set aside too much land. In contrast, expected habitat size under the ex-post scheme is smaller than both the ex-ante and full information allocations.
Provably Secure Virus Detection: Using The Observer Effect Against Malware

Protecting software from malware injection is one of the biggest challenges of modern computer science. Despite intensive efforts by the scientific and engineering community, the number of successful attacks continues to increase. This work sets first footsteps towards a provably secure investigation of malware detection. We provide a formal model and cryptographic security definitions of attestation for systems with dynamic memory, and suggest novel provably secure attestation schemes. The key idea underlying our schemes is to use the very insertion of the malware itself to allow for the systems to detect it. This is, in our opinion, close in spirit to the quantum Observer Effect. The attackers, no matter how clever, no matter when they insert their malware, change the state of the system they are attacking. This fundamental idea can be a game changer. And our system does not rely on heuristics; instead, our scheme enjoys the unique property that it is proved secure in a formal and precise mathematical sense and with minimal and realistic CPU modification achieves strong provable security guarantees. We envision such systems with a formal mathematical security treatment as a venue for new directions in software protection.
Calbindin and calretinin localization in retina from different species

Abstract Calbindin-D28K and calretinin are homologous calcium-binding proteins localized in many neurons of the central nervous system. We have compared polyclonal antibodies against calbindin and calretinin and have shown by western blots using purified calbindin and calretinin from rat that (1) anti-calretinin does not recognize calbindin and (2) anti-calbindin presents some cross-reactivity with calretinin. In this report, we have compared by immunohistochemistry the localization of both calcium-binding proteins in the retina of monkey, pig, sheep, rat, cat, pigeon, and salamander. These results are compared with previous data for chick. There are many differences between species and not within species, but some aspects of the distribution are conserved. All species, except rat and monkey, have some cones which contain calbindin only. Most species also have some bipolar cells containing calbindin only. Calretinin is rarely seen in photoreċeptors or bipolar cells. All species have horizontal cells which contain calretinin or calbindin or both. All species have amacrine cells and ganglion cells containing one or other protein. In the cat ganglion cell layer, the calretinin antisera define a new, asymmetric, type of cell.
School Boards and Education Finance in Manitoba: The Politics of Equity, Access and Local Autonomy

This paper provides an analysis of current educational finance debates in Manitoba within a broader discussion of the essential character of public education in Canada. Arguing that public accessibility and equity, public funding, and public control constitute three touchstones of public education, the paper describes the Manitoba debates over provincial and local funding of schools and the use of property taxes to fund education and analyzes them in relation to these criteria. Significant continued local school board funding from property taxes, along with a greater commitment to provincial equalization initiatives, is the direction that the paper suggests offers the greatest potential for sustaining and nurturing a strong publicly funded school system characterized by both public accessibility and public control.
Implementation and assessment of an early home-based intervention on infant attachment organisation: the CAPEDP attachment study in France

Attachment is a long-term emotional link between infants and their mothers. Attachment quality influences subsequent psychosocial relationships, the ability to manage stress and, consequently, later mental health. Home intervention programmes targeting infant attachment have been implemented in several contexts with varying degrees of efficacy. Within the CAPEDP study (Parental Skills and Attachment in Early Childhood: reduction of risks linked to mental health problems and promotion of resilience), a subsample of 120 families were recruited with the objective of assessing the impact of this home-visiting programme on infant attachment organisation using the Strange Situation Procedure. The present paper describes the methodology used in this ancillary study.
Utility-based Optimal Rate Allocation for Heterogeneous Wireless Multicast

Heterogeneous multicast is an efficient communication scheme especially for multimedia applications running over multihop networks when multicast receivers in the same session require service at different rates commensurate with their capabilities. In this paper, we address the problem of resource allocation for a set of heterogeneous multicast sessions over multihop wireless networks. We propose an iterative algorithm that achieves the optimal rates for a set of heterogeneous multicast sessions such that the aggregate utility for all sessions is maximized. We present the formulation of the multicast resource allocation problem as a non-linear optimization model and highlight the cross-layer framework that can solve this problem in a distributed ad hoc network environment with asynchronous computations. Our simulations show that the algorithm achieves optimal resource utilization, guarantees fairness among multicast sessions, provides flexibility in allocating rates over different parts of the multicast sessions and adapts to changing conditions such as dynamic channel capacity and node mobility. Our results show that the proposed algorithm not only provides flexibility in allocating resources across multicast sessions, but also increases the aggregate system utility and improves the overall system throughput by almost 30% compared to homogeneous multicast.
Chief Executive Officer Remuneration Disclosure Quality: Corporate Responses to an Evolving Disclosure Environment

We examine chief executive officer remuneration disclosure in Australia from 1998 to 2004. Disclosure was first required by the Company Law Review Act 1998 (CLRA98). Despite CLRA98's clear intentions, firms generally failed to comply until the requirements were formalized by Director and Executive Disclosures by Disclosing Entities (AASB1046), issued in 2004. For a sample of 124 firms, we find significant improvements in disclosure concurrent both with CLRA98 and AASB1046. We also find firm size, corporate governance, auditor quality, cross-listing status and public scrutiny to be significant explanations of disclosure. Our results indicate that high quality disclosures will only come about through detailed, black letter requirements and that principle-based legislation involving interpretative discretion is unlikely to produce the desired level of disclosure.
Synthesizing two-fingered grippers for positioning and identifying objects

Most industrial grippers now in use are two-fingered. Among them the parallel-jaw gripper is the simplest. It can partially remove the pose uncertainty of an object through grasping, such as the orientation uncertainty. This paper addresses a new type of grippers with the finger configuration of four circles instead of two parallel lines. It has a number of important advantages. Especially, it achieves form-closure and confines the object to a locally unique pose, so as to remove the pose uncertainty completely. It allows the gripped object to reach this pose freely without loss of required friction in the direction perpendicular to the grasping plane. More information can be acquired for identifying the object and its grasp mode. As a result the identification can be performed at one grasp. The key parameter of a symmetric four-pin gripper is the distance (span) between two pin centers on each finger, which depends upon the object shape and impacts the closure property, Based on a new approach to the grasp geometry, selection and limitations of the span are illustrated.
