A General Optimal Control Model of Human Movement Patterns I: Walking Gait

The biomechanics of the human body gives subjects a high degree of freedom in how they can execute movement. Nevertheless, subjects exhibit regularity in their movement patterns. One way to account for this regularity is to suppose that subjects select movement trajectories that are optimal in some sense. We adopt the principle that human movements are optimal and develop a general model for human movement patters that uses variational methods in the form of optimal control theory to calculate trajectories of movement trajectories of the body. We find that in this approach a constant of the motion that arises from the model and which plays a role in the optimal control model that is analogous to the role that the mechanical energy plays in classical physics. We illustrate how this approach works in practice by using it to develop a model of walking gait, making all the derivations and calculations in detail. We finally show that this optimal control model of walking gait recovers in an appropriate limit an existing model of walking gait which has been shown to provide good estimates of many observed characteristics of walking gait.
Fair Value Accounting for Liabilities and Own Credit Risk

We find that equity returns associated with credit risk changes are attenuated by the debt value effect of the credit risk changes, as Merton (1974) predicts. We find that the relation between credit risk changes and equity returns is significantly less negative for firms with more debt—controlling for asset value changes, credit risk increases (decreases) are associated with equity value increases (decreases). This result obtains across credit risk levels. The relation is associated with changes in both expected cash flows and systematic risk, as reflected in analyst earnings forecasts and equity cost of capital. By inverting the Merton (1974) model, we provide descriptive evidence that if unrecognized debt value changes were recognized in income, but not unrecognized asset value changes, most credit upgrade (downgrade) firms would recognize lower (higher) income. These potentially counterintuitive income effects primarily are attributable to incomplete recognition of contemporaneous asset value changes.
Coalition governments and distributive programs: a simple model

Casual empiricism reveals that a government's program implementation policy frequently fails to maximize the representative citizen's welfare. Inthis paper, I construct a model that incorporates political economy considerations and examine the equilibrium policy distortions that a coalition government begets. I show that coalition governments are fiscally profligate when program benefits are divisible and excessively conservative when these benefits are indivisible. In other words, program characteristics (divisible or indivisible) affect even the qualitative nature of coalition-related policy distortions.
Highly Directive Resonator Antennas based on Composite Right/Left-Handed (CRLH) Transmission Lines

A composite right/left-handed (CRLH) series mode zeroth order resonator antenna (ZORA) and a CRLH half-wavelength antenna (HWA) with tunable directivity are presented and demonstrated to exhibit substantially higher directivity than a conventional patch antenna in the case of a 2.4 GHz (WLAN) design. Due to the special dispersion relation of a CRLH transmission line (TL), the length of CRLH TL resonators can be enlarged while keeping their resonance frequency constant, which yields enhanced directivity. The ZORA has been shown to have a higher efficiency (etaZORA 70%) than the CRLH HWA (etaHWAap40%), comparable to that of a patch antenna, as a result of the perfectly uniform current distribution in the zeroth order mode. In particular, the ZORA due to its versatile characteristics and high performance, is expected to find wide applications in the future.
Hepatoprotective and antioxidant activities of grapeseeds against ethanol-induced oxidative stress in rats

The present study was carried out to evaluate the hepatoprotective effect and antioxidant role of grape (Vitis vinifera L.) seeds (GS) against ethanol-induced oxidative stress. The hepatoprotective and antioxidant roles of the GS supplementation feed against ethanol-induced oxidative stress were evaluated by measuring liver damage serum marker enzymes, aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase and lactate dehydrogenase, antioxidant defence system such as GSH, glutathione reductase, superoxide dismutase, glutathione S-transferase and glutathione peroxidase and malondialdehyde (MDA) content in various tissues of rats. Rats were divided into four experimental groups: I (control), II (20 % ethanol), III (15 % GS) and IV (20 % ethanol+15 % GS). According to the results, the level of serum marker enzymes was significantly increased in group II as compared to that of group I, but decreased in group IV as compared to that of group II. Also, administration of GS-supplemented food restored the ethanol-induced MDA, which was increased near the control level. The results indicated that GS could be as important as diet-derived antioxidants in preventing oxidative damage in the tissues by reducing the lipid oxidation or inhibiting the production of ethanol-induced free radicals in rats.
Robust consumption and portfolio choice for time varying investment opportunities

This paper examines a continuous-time intertemporal consumption and portfolio choice problem for an investor with recursive preferences. The investor worries about model misspecification and seeks robust decision rules. The expected excess return of a risky asset follows a mean-reverting process. I find that whether the concern about model misspecification decreases the total demand for equities largely depends on risk aversion and the attitude toward intertemporal substitution. When the elasticity of intertemporal substitution is about 1 and risk aversion is moderate, the aversion to model uncertainty increases the proportion of wealth invested in equities. The calibration analysis based on detection-error probabilities shows that the quantitative effect of robustness is almost negligible.
Wage moderation in the public sector: The experiences of 11 EMU countries in the recent economic crisis, 2008–2010

The factors that influence wage moderation policies across European countries have been a focus of industrial relations literature for some time. Given the lack of direct market discipline on public sector wages, most existing accounts suggest that the determinants of public sector wages are due to institutional characteristics of the national wage-setting system in question. In this article the authors suggest an alternative ‘functionalist’ explanation of public sector wage determination, with an emphasis on the role of public fiscal constraints and macroeconomic stress. Drawing on new data from 11 EMU countries during the recent economic crisis of 2008–2010 and engaging in a cross-national analysis using Fuzzy-Set Qualitative Comparative Analysis (fsQCA), the authors demonstrate that the functionalist explanation performs better than the institutionalist one in a crisis period.
Capitalism without Capital: Capital Conversion and Market Making in Rural China*

Abstract Situated in an agricultural township in northern China, this study examines the rise of produce markets in rural China in the face of a chronic shortage of financial capital. Drawing on theoretical ideas in economic sociology, we explicate the mechanisms of gift exchange and credit taking and the conditions under which these mechanisms are used to mobilize financial capital and to facilitate market transactions in the absence of financial capital. We illustrate these issues and ideas using our fieldwork research on different produce markets and entrepreneurial activities. 摘要 本文分析讨论了在金融资本短缺条件下中国农产品市场的兴起。 我们从经济社会学的理论思路出发, 提出了动员金融资本和促就市场交易的两个机制 — “礼物互惠”和 “强征性信用”, 以及这些机制发生作用的条件。 文章报告了中国北方一个农业镇上不同农产品市场及其企业家活动的田野研究, 用以阐述本文提出的分析概念和理论思路。
The experiences of parenting a child with an acquired brain injury: A meta-synthesis of the qualitative literature

ABSTRACT Objective. To systematically review and then synthesize the qualitative literature on the experience of parenting a child with an acquired brain injury (ABI). Design. Systematic literature review and meta-synthesis Methods. A systematic search of the literature was conducted in four databases. Papers which met the inclusion criterion were assessed for quality using the Critical Skills Appraisal Programme (CASP) tool and then synthesized according to Noblit and Hare’s (1988) guidelines for meta-ethnography. Results. Of the 4855 papers retrieved, 17 met the inclusion criteria. Synthesis resulted in three themes: (1) Disconnection: Cut off from internal emotions and isolated from others; (2) Seeking understanding and support to manage in an insecure world; and (3) New parent to a different child. Conclusions. Having a child with an ABI leads to many challenges for parents. These include feeling insecure, isolated from others and struggling to adapt to the different roles required to parent their different child. Clinical implications highlight the need for specialist support that is ongoing after discharge, including specialist knowledge and understanding of ABI and opportunities for peer support.
On estimates of split-ticket voting : El and EMax

Cho and Gaines have recently criticized work by Burden and Kimball on split-ticket voting in the USA, suggesting that their estimates of the volume of such voting (derived using King's EI method) across Congressional Districts and States are unreliable. Using part of the Burden-Kimball data set, we report on a parallel set of estimates generated by a different procedure (EMax), which employs three rather than two sets of bounds. The results are extremely similar to Burden and Kimball's, providing strong circumstantial evidence for their conclusions regarding the impact of campaign spending and other influences on the volume of split-ticket voting
A New Perspective on Ownership Identities in China's Listed Companies

We introduce a new perspective on the conceptualization and measurement of ownership identities of China's listed companies. Previous work analyzing the strategy and performance implications of the ownership structure in Chinese firms has used the official categorization provided by state bodies in China. In this categorization, state shareholding, legal person shareholding and A-shares dominate. This official categorization, however, obscures the ultimate identity of a shareholder; this can confound conceptual and empirical work on die strategy and performance implications of ownership identity. We refine the existing classification by recategorizing shareholders into 16 types, which can then be regrouped into relevant categories of shareholders, such as government or private, to enable analysis of ownership identity and ownership concentration issues in China's listed companies. Our new classification can help provide consistency in the burgeoning research on the strategy and performance implications of the concentration and identity aspects of ownership structure in China's listed companies.
Analysis of Islamic banks' financing and economic growth: a panel cointegration approach

Purpose - This paper seeks to use empirical evidence to examine the role of Islamic banks' financing on economic performance of selected countries (Malaysia, Indonesia, Bahrain, UAE, Saudi Arabia, Egypt, Kuwait, Qatar and Yemen). Design/methodology/approach - Using quarterly data (2000:1-2010:4), this paper utilizes the panel cointegration approach models framework. Findings - The results generally signify that, in the long run, Islamic banks' financing is positive and significantly correlated with economic growth and capital accumulation in these countries. The results obtained from the Granger causality test reveal a positive and statistically significant relationship between economic growth and Islamic banks' financing in the short run and in the long run. It also found that the long run relationship is stronger than the short run relationship. Originality/value - This paper uses empirical evidence to show the effect of Islamic banks' financing on economic growth of selected Islamic countries. To the best of the authors' knowledge, most of the studies in this field have applied the bound testing approach of cointegration, error correction models (ECMs), Auto Regressive Distributed lag (ARDL) and Vector Autoregressive Model (VAR), and the coefficients obtained by these models cannot be deemed as a general finding applicable for other countries. The superiority of this article is in applying the FMOLS model, which has stable and consistent coefficients and is also a dynamic model.
Community Treatment Orders: Relationship to Clinical Care, Medication Compliance, Behavioural Disturbance and Readmission

Objective: The objective of this study was to investigate the readmission rate, and the level of patient disturbance and community care associated with readmission following Community Treatment Orders (CTOs) in New South Wales, Australia. Method: The readmission rates of all patients given CTOs within a 4-year period and a matched comparison group were investigated. The following factors were compared before, during and following a CTO: medication non-compliance, number of clinical services and duration of disturbed behaviour preceding hospitalisations. Results: Of 123 patients on CTOs (mean length, 288 days; SD, 210 days), 38 were readmitted during the CTO, the majority in the first 3 months and a further 21 patients were readmitted following termination of the CTO. Evidence of lower severity of illness in the comparison patients prevented meaningful evaluation of the readmission rates of the two groups. While on CTOs, patients receiving depot medications showed high compliance and a significantly reduced readmission rate compared with that of patients receiving oral medications. In the 2 months prior to hospitalisations during CTOs, compared with those before or after CTOs, patients received more frequent consultations and showed a shorter duration of medication non-compliance and disturbed behaviour. The level of services in the 3 months following discharge were comparable for patients on CTOs and the comparison group. Conclusions: CTOs may reduce rehospitalisations by use of depot medication. Earlier and possibly more frequent readmissions in the CTO group shortened the disturbance associated with illness recurrence. It would appear that to establish a control group with equivalent severity of disorder necessary to evaluate the impact of CTOs requires a random allocation design.
Up-to-date long-term survival curves of patients with cancer by period analysis.

PURPOSE Provision of up-to-date long-term survival curves is an important task of cancer registries. Traditionally, survival curves have been derived for cohorts of patients diagnosed many years ago. Using data of the Finnish Cancer Registry, we provide an empirical assessment of the use of a new method of survival analysis, denoted period analysis, for deriving more up-to-date survival curves. PATIENTS AND METHODS We calculated 10-year relative survival curves actually observed for patients diagnosed with one of the 15 most common forms of cancer in 1983 to 1987, and we compared them with the most up-to-date 10-year relative survival curves that might have been obtained in 1983 to 1987 using either traditional (cohort-wise) or period analysis. We also give the most recent 10-year survival curves obtained by period analysis for the 1993 to 1997 period. RESULTS For all forms of cancer, period analysis of the 1983 to 1987 data yielded survival curves that were very close to the survival curves later observed for patients who were newly diagnosed in that period (median and maximum difference of 10-year relative survival estimates: 0.9 and 5.7 percent units, respectively). By contrast, the survival curves obtained by traditional (cohort-wise) survival analysis in 1983 to 1987 would have been much lower for most forms of cancer (median and maximum difference: 5.8 and 18.4 percent units, respectively). The 10-year survival curves for the 1993 to 1997 period are substantially more favorable than previously available, traditionally derived survival curves for most forms of cancer. CONCLUSION Period analysis is a useful tool for deriving up-to-date long-term survival curves of patients with cancer.
Corporate reports on sustainability and sustainable development: ‘We Have Arrived’

This paper analyses how the world's largest corporations communicate about sustainability and sustainable development in their non-financial reports. It investigates the concept use, definitions and attempts at operationalization, and the rationales that corporations give to engage with them. It is concluded that the corporations typically opt to treat sustainability and sustainable development as given and unproblematic instead of addressing the fundamental problems of today's practice or the dilemmas of the concepts. The most striking finding, however, is that so many of the corporations no longer argue that they are on a ‘journey’ towards sustainability, but that they have already integrated sustainability principles and that they have worked like this for years. Such arguments arguably inhibit the change in business models that many commentators call for. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.
Pro-FHH: A Risk Equation to Facilitate the Diagnosis of Parathyroid-Related Hypercalcemia

Context Parathyroid-related hypercalcemia is due to primary hyperparathyroidism (PHPT) or to familial hypocalciuric hypercalcemia (FHH). PHPT can lead to complications that necessitate parathyroidectomy. FHH is a rare genetic disease resembling PHPT; surgery is ineffective. A reliable method for distinguishing FHH from PHPT is needed. Objective To develop an easy-to-use tool to predict if a patient has PHPT. Design Retrospective analysis of two prospective cohorts. Development of an unsupervised risk equation (Pro-FHH). Setting University hospitals in Paris, France, and Aarhus, Denmark. Participants Patients (Paris: 65 with FHH, 85 with PHPT; Aarhus: 38 with FHH, 55 with PHPT) were adults with hypercalcemia and PTH concentration within normal range. Main Outcome Measures Performance of Pro-FHH to predict PHPT. Results Pro-FHH takes into account plasma calcium, PTH, and serum osteocalcin concentrations, and calcium-to-creatinine clearance ratio calculated from 24-hour urine collection (24h-CCCR). In the Paris cohort, area under the receiver operating characteristic curve (AUROC) of Pro-FHH was 0.961, higher than that of 24h-CCCR. With a cutoff value of 0.928, Pro-FHH had 100% specificity and 100% positive predictive value for the diagnosis of PHPT; it correctly categorized 51 of 85 patients with PHPT; the remaining 34 were recommended to undergo genetic testing. No patients with FHH were wrongly categorized. In an independent cohort from Aarhus, AUROC of Pro-FHH was 0.951, higher than that of 24h-CCCR. Conclusion Pro-FHH effectively predicted whether a patient has PHPT. A prospective trial is necessary to assess its usefulness in a larger population and in patients with elevated PTH concentration.
A framework for institutionalizing quality assurance.

OBJECTIVE To develop a framework to support the institutionalization of quality assurance (QA). DESIGN The framework for institutionalizing QA consists of a model of eight essential elements and a 'roadmap' for the process of institutionalization. The essential elements are the building blocks required for implementing and sustaining QA activities. Core QA activities include defining, measuring and improving quality. The essential elements are grouped under three categories: the internal enabling environment (internal to the organization or system), organizing for quality, and support functions. The enabling environment contains the essential elements of leadership, policy, core values, and resources. Organizing for quality includes the structure for implementing QA. Three essential elements are primarily support functions: capacity building, communication and information, and rewarding quality. The model can be applied at the level of an organization or a system. The paper also describes the process of institutionalizing QA, starting from a state of preawareness, passing through four phases (awareness, experiential, expansion, and consolidation), and culminating in a state of maturity. The process is not linear; an organization may regress, vacillate between phases, or even remain stagnant. Some phases (e.g. awareness and experiential) may occur simultaneously. CONCLUSION The framework has been introduced in nearly a dozen countries in Latin America and Africa. The conceptual model has been used to support strategic planning and directing Ministry of Health work plans, and also as a resource for determining the elements necessary to strengthen and sustain QA. The next step will be the development and evaluation of an assessment tool to monitor developmental progress in the institutionalization of QA.
Blockade of Neurotensin Receptor by SR 48692 Potentiates the Facilitatory Effect of Haloperidol on the Evoked In Vivo Dopamine Release in the Rat Nucleus Accumbens

Abstract: The present experiments assessed the effects of SR 48692, a selective nonpeptide antagonist of neurotensin receptors, on mesolimbic dopaminergic neurotransmission. Dopamine release evoked by the electrical stimulation of the median forebrain bundle (20 Hz, 10 s) was measured in the nucleus accumbens of urethane‐anesthetized rats using differential pulse amperometry combined with carbon fiber electrodes. SR 48692 (0.1 mg/kg, i.p.) alone did not affect this release, whereas it dose‐dependently (0.03–1 mg/kg, i.p.) enhanced the haloperidol (50 µg/kg, i.p.)‐induced facilitation of the electrically evoked DA release. The increase induced by haloperidol (92 ± 26% above control values 30 min after injection) was potentiated by SR 48692 (264 ± 75% at 0.03 mg/kg, 428 ± 113% at 0.1 mg/kg, and 480 ± 135% at 1 mg/kg). Effects identical to those of SR 48692 were obtained with SR 48527, a chemically related compound with a high affinity for neurotensin receptors, but not with SR 49711, its low‐affinity antipode. The potentiating effects of SR 48692 were positively related to the stimulation frequency (from 6 to 20 Hz) and to the dose of haloperidol (from 12.5 to 50 µg/kg) and were abolished after prior kainic acid lesion (1 µg/1 µl) of the nucleus accumbens. Thus, the effects of SR 48692 required the integrity of postsynaptic elements of the nucleus accumbens and occurred under the combination of two, at least partly, interdependent conditions: strong D2 autoreceptor blockade and high‐intensity stimulation likely to release neurotensin. It is interesting that these potentiating effects of SR 48692 did not appear in the striatum. In conclusion, these findings suggest that endogenous neurotensin may attenuate the facilitation of D2 receptor blockade on mesolimbic but not nigrostriatal dopamine transmission.
