The Global Employer: The Labor Relations and Collective Agreements Issue

[Excerpt] Baker & McKenzie’s Global Employment Practice Group is pleased to present its 56th issue of The Global Employer™ entitled “The Labor Relations and Collective Agreements Issue.” In this issue you will find the first report from our Future of Work Series. Labor Relations Report - Brand Attack: How to avoid becoming the target of a corporate campaign and what actions to take if you do. The Future of Work is a series of client reports based on panel discussions at our Global Employer Forum, a two-day thought leadership conference. During the forum, nearly 70 clients, academics and consultants gathered with our employment partners to discuss pressing workplace topics like talent shortages, data privacy, global mobility assignments, globalization of unions and managing the employment aspects of M&A deals. Rather than the traditional “how to” legal format of most law firm conferences, the Global Employer Forum features panel discussions of in-house counsel and senior-level executives from some of the world’s largest multinational organizations who discussed their personal experiences addressing these challenges and the solutions they have found to overcome them. Following the Labor Relations Report, you will also find information pertaining to the current state of labor relations and union negotiations in Argentina and a general overview of the current state of collective bargaining in Brazil. In Germany, we take a look at some of the numbers behind collective bargaining agreements; and a review of the impacts on labor benefits of the January 2014, Income Tax Law reform in Mexico. From Spain we bring you articles that discuss negotiating with representatives bodies in collective lay-offs and the new role of company level collective bargaining agreements; and from the US, recent efforts by the NLRB as it Targets Successor Issues in US Mergers and Acquisitions

The Global Employer: The Employment Law Review and Reform Issue

[Excerpt] Although the economies of many jurisdictions are improving, there is still some lingering global economic uncertainty. It is no surprise that governments the world over continue to revisit their employment laws to see what else, if anything, can be done to further stimulate their economies. 2013 was another busy year for employment law reform. Baker & McKenzie’s Global Employment Practice Group is pleased to present its 55th issue of The Global Employer™ entitled “The Employment Law Review and Reform Issue.” In this issue, we review changes to the law in 2013 and a look at pending changes for 2014. Included, you will find information pertaining to the leasing of employees in Germany; new measures in Spain intended to promote employment among young people under 30 and employee privacy rights over employers\u27 controls; challenges to the applicable interest rate to worker\u27s claims in Argentina; how employment law reforms will significantly impact employers in Mexico and in some specific cases, may considerably elevate increase the cost of formal employment; and controversy around making the Colombian Social Security System more progressive. We also review several significant legal developments in China during 2013 that impact employers operating there; legislative changes that were expected in Hong Kong in 2013 that may be implemented in 2014 including a focus on discrimination in the coming years; and welcome changes to TUPE and automatic pension plan enrollment in the United Kingdom

Optimal Contracting with Verifiable Ex Post Signals

We study an adverse selection problem in which information that is imperfectly correlated with the agent's type becomes public ex post. Unbounded penalties are ruled out by assuming that the agent is wealth constrained. The following conclusions emerge. If the agent's utility is increasing in the contractual action (e.g. the quantity traded), the downward distortion in bad states may be strengthened. Hence, ex post information can reduce efficiency. In contrast, if the agent's utility is decreasing in the action level, there may be an upward distortion. Moreover, his rent may increase due to the ex post signal about his type. The qualitative results thus differ substantially depending on the specific situation under consideration, e.g., whether the agent is in a `buyer' or `seller' position. In both cases, however, additional information need not improve the efficiency of the relationship

Binning is Sinning: Redemption for Hubble Diagram using Photometrically Classified Type Ia Supernovae

Bayesian Estimation Applied to Multiple Species (BEAMS) has been implemented in the BEAMS with Bias Corrections (BBC) framework to produce a redshift-binned Hubble diagram (HD) for Type Ia Supernovae (SN Ia). The BBC method corrects for selection effects and non-SNIa contamination, and systematic uncertainties are described by a covariance matrix with dimension matching the number of BBC redshift bins. For spectroscopically confirmed SNIa samples, a recent "Binning is Sinning" article (BHS21, arxiv:2012.05900) showed that an unbinned HD and covariance matrix reduces the systematic uncertainty by a factor of 1.5 compared to the binned approach. Here we extend their analysis to obtain an unbinned HD for a photometrically identified sample processed with BBC. To test this new method, we simulate and analyze 50 samples corresponding to the Dark Energy Survey (DES) with a low-redshift anchor; the simulation includes SNe Ia, and contaminants from core collapse SNe and peculiar SNe Ia. The analysis includes systematic uncertainties for calibration, and measures the dark energy equation of state parameter (w). Compared to a redshift-binned HD, the unbinned HD with nearly 2,000 events results in a smaller systematic uncertainty, in qualitative agreement with BHS21, and averaging results among the 50 samples we find no evidence for bias in measured cosmological parameters. To reduce computation time for fitting an unbinned HD with large samples, we propose an HD-rebinning method that defines the HD in bins of redshift, color, and stretch; the rebinned HD results in similar uncertainty as the unbinned case, and shows no evidence for biased cosmology parameters

Expression of citrulline and homocitrulline residues in the lungs of non-smokers and smokers : implications for autoimmunity in rheumatoid arthritis

Introduction: Smoking is a well-established risk factor for rheumatoid arthritis (RA), and it has been proposed that smoking-induced citrullination renders autoantigens immunogenic. To investigate this mechanism, we examined human lung tissue from 40 subjects with defined smoking status, with or without chronic obstructive pulmonary disease (COPD), and control tissues from other organs for citrullinated proteins and the deiminating enzymes peptidylarginine deiminase type-2 (PAD2) and -4 (PAD4). Methods: Lung tissue samples, dissected from lobectomy specimens from 10 never smokers, 10 smokers without airflow limitation, 13 COPD smokers and eight COPD ex-smokers, and control tissue samples (spleen, skeletal muscle, liver, ovary, lymph node, kidney and heart), were analysed for citrullinated proteins, PAD2 and PAD4 by immunoblotting. Citrulline and homocitrulline residues in enolase and vimentin were analysed by partial purification by gel electrophoresis followed by mass spectrometry in 12 of the lung samples and one from each control tissues. Band intensities were scored semi-quantitatively and analysed by two-tailed Mann-Whitney T-test. Results: Within the lung tissue samples, citrullinated proteins, PAD2 and PAD4 were found in all samples, with an increase in citrullination in COPD (P = 0.039), but minimal difference between smokers and non-smokers (P = 0.77). Citrullination was also detected at lower levels in the tissues from other organs, principally in lymph node, kidney and skeletal muscle. Mass spectrometry of the lung samples showed that vimentin was citrullinated at positions 71, 304, 346, 410 and 450 in non-smokers and smokers both with and without COPD. A homocitrulline at position 104 was found in four out of six COPD samples and one out of six non-COPD. Citrulline-450 was also found in three of the control tissues. There were no citrulline or homocitrulline residues demonstrated in a-enolase. Conclusions: We have shown evidence of citrullination of vimentin, a major autoantigen in RA, in both non-smokers and smokers. The increase in citrullinated proteins in COPD suggests that citrullination in the lungs of smokers is mainly due to inflammation. The ubiquity of citrullination of vimentin in the lungs and other tissues suggests that the relationship between smoking and autoimmunity in RA may be more complex than previously thought

Testing Models of Intrinsic Brightness Variations in Type Ia Supernovae, and their Impact on Measuring Cosmological Parameters

For spectroscopically confirmed Type Ia supernovae we evaluate models of intrinsic brightness variations with detailed data/Monte Carlo comparisons of the dispersion in the following quantities: Hubble-diagram scatter, color difference (B-V-c) between the true B-V color and the fitted color (c) from the SALT-II light curve model, and photometric redshift residual. The data sample includes 251 ugriz light curves from the 3-season Sloan Digital Sky Survey-II, and 191 griz light curves from the Supernova Legacy Survey 3-year data release. We find that the simplest model of a wavelength-independent (coherent) scatter is not adequate, and that to describe the data the intrinsic scatter model must have wavelength-dependent variations. We use Monte Carlo simulations to examine the standard approach of adding a coherent scatter term in quadrature to the distance-modulus uncertainty in order to bring the reduced chi2 to unity when fitting a Hubble diagram. If the light curve fits include model uncertainties with the correct wavelength dependence of the scatter, we find that the bias on the dark energy equation of state parameter $w$ is negligible. However, incorrect model uncertainties can lead to a significant bias on the distance moduli, with up to ~0.05 mag redshift-dependent variation. For the recent SNLS3 cosmology results we estimate that this effect introduces an additional systematic uncertainty on $w$ of ~0.02, well below the total uncertainty. However, this uncertainty depends on the samples used, and thus this small $w$-uncertainty is not guaranteed in future cosmology results.Comment: accepted by Ap

Iron Ore Tailings Dewatering: Measurement of Adhesion and Cohesion for Filter Press Operation

Globally, mining operators focus increasingly on tailings filtration to recover process water and store tailings more safely. Generally, required water contents below 20-w% are reached by using filter presses. To maintain high efficiency, complete cake detachment is needed because incomplete discharge reduces plant performance. However, filter cake discharge can occur in different ways, mainly influenced by adhesion of the filter cake to the filter cloth as well as by cohesion of the cake. Therefore, this study points out different major detachment behaviors and a theoretical approach to describe them. Furthermore, investigations on iron ore tailings filtrations were carried out to show the influences of different filter media, different filtration pressure and cake post-treatment on adhesion and cohesion
