Extending Employment beyond Retirement Age: The Case of Health Care Managers in Quebec

Baby boomers in public agencies are getting ready to retire and there are concerns about retaining the existing workforce apart from recruiting younger managers. Recent studies of workplace patterns of older workers have shown that the workforce of older workers should no longer be seen as a unidirectional journey to retirement. Older workers may value bridge employment or even prefer to extend their working lives. The motives for deciding to leave the workplace permanently can be related to unmet expectations, the desire for change, and the need to enjoy a new phase of life. Based on a survey conducted on 402 older managers working in health care institutions in Quebec, this study sheds light on the new alternatives to traditional early retirement that organizations will have to take into account while considering the preferences and intentions of employees who are approaching retirement.
An Empirical Test of Ross's Cash Flow Beta Theory of Capital Structure

This paper empirically investigates Stephen A. Ross's (1985) cash flow beta theory of capital structure. Ross hypothesizes that, for firms of similar cash flow variance, there will be an inverse relationship between financial leverage and cash flow beta. This paper provides empirical support for Ross's theory, though the extent of the support depends upon the sample period and the leverage specification. Copyright 1989 by MIT Press.
How Do Different Levels of User Control Affect Cognitive Load and Acceptance of Recommendations?

User control has been recognised as an important feature in recommender system, as it allows users to steer the recommendation process. Most typical user controls relate to providing ratings, editing user data, and adjusting weights of the algorithm. The cognitive load of the user may increase when using more advanced user controls. We divided common user controls into three levels (high, middle, and low) and conducted a study (N=90) to investigate how different levels of user control affect cognitive load and quality of recommendations. We designed a visualisation on top of a music recommender system that incorporates three levels of control. The study results show that high level control tends to produce the best recommendations, while requiring the highest cognitive load. However, only participants with rich experience in recommender systems are more likely to tweak such high level control, while the majority of participants still prefers low and middle level control. We validated the robustness of our findings with three different algorithms. ACM Classification
VanD-type glycopeptide-resistant Enterococcus faecium BM4339

Enterococcus faecium BM4339 was constitutively resistant to vancomycin (MIC, 64 microg/ml) and to low levels of teicoplanin (MIC, 4 microg/ml). A 605-bp product obtained with the V1 and V2 primers for amplification of genes encoding D-Ala:D-Ala ligases and related glycopeptide resistance proteins was sequenced after cloning. The deduced amino acid sequence had 69% identity with VanA and VanB and 43% identity with VanC, consistent with the finding that BM4339 synthesized peptidoglycan precursors terminating in D-lactate. This new type of glycopeptide resistance phenotype was designated VanD.
Viscosity sensor utilizing a piezoelectric thickness shear sandwich resonator

This paper describes a novel quartz crystal sensor for measurement of the density-viscosity product of Newtonian liquids. The sensor element consists of two piano-convex AT-cut quartz crystals vibrating in a thickness-shear mode with the liquid sample in between. This special set-up allows suppression of disturbing resonances in the liquid layer. Such resonances are generated in the common single-plate arrangements due to compressional waves caused by spurious out-of-plane displacements of the shear vibrating finite plate. The primary measurands of the sensor are the fundamental resonance frequency and the associated resonance Q-value, which are influenced by the viscously entrained liquid contacting the quartz surface. The sensor allows the measurement of samples with viscosities from almost zero (air! ) up to 200 cP with a sample volume of 130 /spl mu/l.
How Do Respondents with Uncertain Willingness to Pay Answer Contingent Valuation Questions?

Four elicitation methods are compared in a split-sample, contingent-valuation study valuing avoidance of episodes of ill health linked to air pollution: two discrete methods and two more-continuous methods. Respondents to a traditional payment card (PC) question gave willingness-to-pay values that were lower than those implied by dichotomous-choice (DC) responses. However, follow up questions showed that DC respondents were less certain of their stated behavior than were PC respondents. When respondents were told to be “almost certain” of their responses, responses to the DC and the PC formats converged. (JEL Q21)
Interaction of Enteropathogenic or Enterohemorrhagic Escherichia coli with HeLa Cells Results in Translocation of Cortactin to the Bacterial Adherence Site

ABSTRACT Infection of cultured HeLa epithelial cells with enteropathogenicEscherichia coli (EPEC) or enterohemorrhagic E. coli (EHEC) O157:H7 results in accumulation of cortactin under the adherent bacteria. Tyrosine phosphorylation of cortactin is not induced following HeLa cell infection with EHEC or EPEC, contrary to what has been reported to occur with Shigella flexneri.
Asymmetries in the Valuation of Risk and the Siting of Hazardous Waste Disposal Facilities

Recently several economists (Richard Thaler, 1980; Jack Knetsch and J. A. Sinden, 1984), following suggestions of psychologists (Daniel Kahneman and Amos Tversky, 1979), have argued that current economic models of consumer behavior fail to explain observed asymmetries in how individuals respond to gain vs. losses in perceived entitlements. Attention to their arguments is increasing because they relate to many current policy issues-especially those associated with undesirable land uses. Most of the papers suggesting this limitation with the conventional economic framework have been motivated by the large differences between the estimates of willingness to pay vs. willingness to accept as measures of the change in individual well-being that would result from a change in the conditions of access to (or the quality of) a commodity. ' In this paper we report the first evidence of a sizable property rights effect using only willingness-to-pay measures. This change is potentially important because both the recent appraisal of contingent valuation surveys (see Ronald Cummings et al. 1986), an important source of the available empirical evidence, and laboratory experiments suggest that individuals may have difficulty in dealing with the concept of compensation. This is especially true when there is no opportunity for individuals to learn about transactions that involve compensation through experience. Based on a contingent valuation survey of households in suburban Boston, we found that respondents bid significantly more to reduce risk than they indicated they were willing to pay to avoid an equivalent risk increase. While our findings support suggestions that changes in the implied entitlements (to safety) can lead to large differences in welfare measures for risk changes, several of these earlier arguments would have implied that individuals were willing to pay more to avoid a risk increase-the opposite to our results. Thus, these differences imply that the determinants of individuals' valuations for risk changes are more complex than past studies have acknowledged.
A 500-MS/s, 2.0-mW, 8-Bit Subranging ADC with Time-Domain Quantizer

This paper describes a novel energy-efficient, high-speed ADC architecture combining a flash ADC and a TDC. A high conversion rate can be obtained owing to the flash coarse ADC, and low-power dissipation can be attained using the TDC as a fine ADC. Moreover, a capacitive coupled ramp circuit is proposed to achieve high linearity. A test chip was fabricated using 65-nm digital CMOS technology. The test chip demonstrated a high sampling frequency of 500 MHz and a low-power dissipation of 2.0 mW, resulting in a low FOM of 32 fJ/conversion-step.
INEQUALITY OF DISTRIBUTION AND POVERTY INCIDENCE IN THE ADJUSTMENT PERIOD AND ANALYSIS OF ECONOMIC CRISIS IMPACT IN INDONESIA

Artikel ini menganalisis faktor-faktor yang mempengaruhi ketimpangan distribusi pendapatan di Indonesia selama awal pembangunan (adjustment period) dan sebagai dampak krisis ekonomi menggunakan unbalanced panel method untuk 26 propinsi di Indonesia (tidak termasuk Timor Timur, Bangka Belitung, Banten, dan Gorontalo) untuk periode 1980-2002. Selama periode awal pembangunan (adjustment period), meskipun kemiskinan di Indonesia mengalami penurunan yang signifikan, namun ketimpangan distribusi cenderung konstan. Lebih jauh, isu ini menghangat sejak Indonesia mengalami keterpurukan akibat krisis ekonomi tahun 1997-1998. Studi empiris ini memberikan hasil bahwa semua variabel sosial ekonomi, yaitu expenditure per capita, school enrolment, poor people, average household size, population density, dan revenue per capita, dan variabel yang menunjukkan krisis ekonomi signifikan mempengaruhi ketimpangan distribusi di Indonesia. Permasalahannya kemudian bukan saja ketimpangan distribusi, namun juga munculnya isu disintegrasi yang semakin marak. Oleh karena itu dalam artikel ini direkomendasikan bahwa kebijakan pemerintah seharusnya difokuskan kepada variabel kebijakan yang signifikan mempengaruhi ketimpangan distribusi di Indonesia termasuk di dalamnya implementasi desentralisasi yang masih merupakan tantangan besar dalam menjawab isu disintegrasi.
Context Information-Based Cyber Security Defense of Protection System

With the development of a substation automation system, it is now feasible for the intelligent electronic devices-based protection system to collect its measurements from electronic instrument transformers through a communication network such as an Ethernet-based local-area network. The application of a wide-area broadband network in power utilities introduces underlying danger for protection systems to maloperate when receiving fake data packages from an intruder. This paper proposes identifying a vicious fault by using context information, such as voltage and current, of the same substation. When the protection system detects a fault based on measurements transmitted through a network, it collects all measurements of the substation and feeds these data to a probabilistic neural network. Thereafter, the fault caused by fake data that differs from the known fault pattern can be identified and blocked.
Mismatched intratumoral distribution of [18F] fluorodeoxyglucose and 3′-deoxy-3′-[18F] fluorothymidine in patients with lung cancer

In a mouse model of human lung cancer, intratumoral distribution between 3′-deoxy-3′-[18F] fluorothymidine (18F-FLT) and [18F] fluorodeoxyglucose (18F-FDG) was mutually exclusive. 18F-FLT primarily accumulated in proliferating cancer cells, whereas 18F-FDG accumulated in hypoxic cancer cells. The aim of the present study was to evaluate these preclinical findings in patients with lung cancer. A total of 55 patients with solitary pulmonary lesion were included in the present study. Patients underwent 18F-FLT positron emission tomography-computed tomography (PET/CT) and 18F-FDG PET/CT scan with a 3-day interval. The final diagnosis was based on histological examination. Among the 55 cases, a total of 24 cases were confirmed as malignant lesions. Mismatched 18F-FLT- and 18F-FDG-accumulated regions were observed in 19 cases (79%) and matched in 5 (21%). Among the 31 benign lesions, 18F-FLT and 18F-FDG were mismatched in 12 cases (39%) and matched in 19 (61%). The difference in intratumoral distribution of 18F-FLT and 18F-FDG between malignant and benign lesions was statistically significant (P<0.05). The results of the present study indicate that a mismatch in intratumoral distribution of 18F-FLT and 18F-FDG may be a feature of patients with lung cancer. Increased 18F-FDG accumulation may serve as an indicator of tumor hypoxia, whereas regions with increased 18F-FLT uptake may be associated with an increased rate of cancer cell proliferation in patients with lung cancer.
Progesterone and its metabolites as therapeutic targets in psychiatric disorders

Introduction: Neurosteroids are molecules that regulate physiological functions of the CNS. There is increasing evidence suggesting that impaired neurosteroid biosynthesis has been associated with distinct psychiatric disorders. This review summarizes data from studies that have investigated the relationship between progesterone (PROG) and psychiatric disorders as well as the mechanisms potentially involved in PROG-induced neuroprotection. Areas covered: The review covers the role of PROG and its metabolites in psychiatric disorders, focusing on results from preclinical and some clinical studies that support the relationship between alterations on PROG levels and pathophysiology of psychiatric illness. We also discussed the main mechanisms underlying the neuroprotective effects of PROG metabolites. Expert opinion: Our review points out the possible relationship between PROG and its metabolites and the pathophysiology of psychiatric disorders. Furthermore, both preclinical and clinical studies show that certain treatments (antidepressants or antipsychotics) may normalize the levels of PROG, suggesting that the amelioration of psychiatric symptoms may occur due to upregulation of PROG metabolites. Therefore, these results give support to new possibilities of treatment for patients with psychiatric symptoms from anxiety- and depressive-like behaviors to aggressive behaviors.
Iopanoic acid‐induced decrease of circulating T3 causes a significant increase in GH responsiveness to GH releasing hormone in thyrotoxic patients

Thyroid hormones participate in GH synthesis and secretion, and an impaired GH response to many pharmacological stimuli, including GH releasing hormone (GHRH), has been found in thyrotoxicosis. Although the mechanisms involved in this process have not been fully elucidated, there is evidence that thyroid hormones could act at both hypothalamic and pituitary levels. There are no data in the literature about the effect of an acute reduction of circulating T3 levels on GH secretion in hyperthyroidism. The GH responsiveness to GHRH was therefore evaluated in a group of hyperthyroid patients during short‐term treatment with iopanoic acid. Iopanoic acid is a compound that induces a rapid decrease in serum T3 levels, mainly by inhibition of peripheral conversion of T4 to T3. To the authors' knowledge, there is no evidence of a direct effect of iopanoic acid on GH secretion.
Spectrum Abundance and the Choice Between Private and Public Control

Prominent commentators recently have proposed that the government allocate significant portions of the radio spectrum for use as a wireless commons. The problem for commons proposals is that truly open access leads to interference, which renders a commons unattractive. Those advocating a commons assert, however, that a network comprising devices that operate at low power and repeat each other's messages can eliminate the interference problem. They contend that this possibility renders a spectrum commons more efficient than privately owned spectrum, and in fact that private owners would not create these 'abundant networks' in the first place. In this Article, Professor Benjamin argues that these assertions are not well founded, and that efficiency considerations favor private ownership of spectrum. Those advocating a commons do not propose a network in which anyone can transmit as she pleases. The abundant networks they envision involve significant control over the devices that will be allowed to transmit. On the question whether private entities will create these abundant networks, commons advocates emphasize the transaction costs of aggregating spectrum, but those costs can be avoided via allotment of spectrum in large swaths. The comparative question of the efficiency of private versus public control, meanwhile, entails an evaluation of the implications of the profit motive (enhanced ability and desire to devise the best networks, but also the desire to attain monopoly power) versus properties of government action (the avoidance of private monopoly, but also a cumbersome process that can be subject to rent-seeking). Professor Benjamin contends that, on balance, these considerations favor private control. An additional factor makes the decision clearer: Abundant networks might not develop as planned, and so the flexibility entailed by private ownershipas well as the shifting of the risk of failure from taxpayers to shareholdersmakes private ownership the better option. The unattractiveness of a commons for abundant networks casts serious doubt on the desirability of spectrum commons more generally. If private ownership is a more efficient means of creating abundant networks, then the same is almost certainly true for networks that run the risk of interference. Most uses of spectrum are subject to interference, so the failure of the commons advocates' arguments undermines the appeal of a commons for most potential uses of spectrum.
Measurement of cardiac output with and organ trapping of radioactive microspheres.

Cardiac output in dogs and lambs was measured with radioactive microspheres. The radioactivity injected (I/sub i/) into left atrium and in an arterial reference sample (I/sub ar/) drawn at constant rate (Q/sub ar/,) during injection was counted; cardiac output (CO) = Q/sub ar/(I/sub i/I/sub ar/) . On comparison with known flows this method was accurate and precise (r = 0.94, s/sub y,x/ = 0.11 liter/min). Comparing nonsimultaneous indocyanine green and microsphere cardiac outputs gave more variability (r = 0.90, s/sub y,x/ = 0.41 liter/min). A method is also presented of determining organ extraction of microspheres after left atrial injection from reference samples from any artery and a representative vein draining the organ being studied. The percentages of radioactivity of microspheres 4-12- mu -diameter not trapped by heart, kidney, and systemic circulation of lambs were 3.6 plus or minus 2.9%, 2.8 plus or minus 1.9%, and 5.5 plus or minus 2.2% (mean and standard deviation). Under 0.1% of the radioactivity of 15- mu -diameter spheres and 4--26% of the radioactivity of 4--12- mu -diameter spheres were not trapped by dog kidneys. These results are based on radioactivity measurements and do not account for variations in sizes of trapped and nontrapped spheres.more » Diameters of nontrapped spheres compared to injected spheres suggest that nontrapping in the lamb was due to spheres under 7 mu diameter.

6D-3 Simplified Green Function Techniques for General SAW Device Analysis and Optimization

In recent years, the Green function, or boundary element (BEM), method has become the preferred technique for rigorous SAW device analysis. However, because of its computational cost, its principal application has been the analysis of mode propagation in periodic structures to determine parameters that can then be used in simplified coupling of modes (COM) or P-matrix models. This paper describes methods for approximate Green function analysis that can combine high accuracy with modest computational cost. Green function approximations are derived by a judicious choice of discrete modes to characterize the continuous mode spectrum, and by restricting the number of independent displacement components employed. The resulting procedure is efficient enough to be applied directly to the analysis and optimization of components such as LCRFs (longitudinally coupled resonator filters), using either leaky wave or surface wave modes
Clinical features and treatment outcomes of dental implant-related paranasal sinusitis: A 2-year prospective observational study.

OBJECTIVES As dental implant-related paranasal sinusitis has different pathophysiology and clinical features from primarily rhinogenic paranasal sinusitis, the standard treatment protocol for dental implant-related paranasal sinusitis has not yet been established. The aim of this study was to analyze the clinical characteristics and treatment results of dental implant-related paranasal sinusitis. MATERIAL AND METHODS We conducted a prospective single-center study of 19 patients who were treated for odontogenic sinusitis developing in relation to dental implant from September 2008 through May 2012. The age of the patients ranged from 33 to 78 years, with the mean age of 54.5 years. Foul odor and postnasal dripping were the two most common complaints. All patients underwent nasal endoscopic examination and paranasal sinus CT before treatment, and initial conservative treatment for 1 week. Patients unresponsive to medical treatment underwent endoscopic sinus surgery (ESS). All patients were classified into the conservative and surgical groups for analysis and followed up for 2 years after initial diagnosis. RESULTS Four patients (21%) were successfully treated conservatively, while 15 patients (79%) underwent surgical treatment. One of these 15 patients required revision surgery. After 2 years, all patients were successfully treated, so there were no more clinical signs of recurrent sinusitis in any patients. The survival rate of implants was 100%. Compared to those of the conservative group, symptom duration, the Lund-MacKay CT score, status of the ostiomeatal unit (OMU), and the condition of the maxillary sinus floor were significantly more severe in the surgical group. CONCLUSION In our study, the majority of patients who once developed paranasal sinusitis associated with dental implants required surgical treatment. Findings of paranasal sinus CT may be important in determining treatment option.
Business Cycles Synchronicity and Income Levels: Has Globalisation Brought Us Closer than Ever?

Research on business cycle linkages shows a tendency to model countries of relatively the same income levels jointly. However, the issue of whether these countries move along the same business cycles has not been formally investigated in the literature. In this paper, we take this approach and investigate whether each group of countries follows its own dynamics and is therefore subjected to the same business cycle and whether these cycles are independent of each other across income groups. Results indicate that high income per capita countries (HICs) tend to be guided by stronger similarity in business cycles than countries in the middle (MICs) and low income (LICs) groups. In search for an explanation of the business cycles synchronicity observed, panel data analysis was explored. The results from the robust fixed effects estimation show neither trade openness nor shocks to consumption underlie international business cycle synchronization, but rather shocks to oil prices.
