The 2004 Global Labor Survey: Workplace Institutions and Practices Around the World
The 2004 Global Labor Survey (GLS) is an Internet-based survey that seeks to measure de facto labor practices in countries around the world, covering issues such as freedom of association, the regulation of work contracts, employee benefits and the prevalence of collective bargaining. To find out about de facto practices, the GLS invited labor practitioners, ranging from union officials and activists to professors of labor law and industrial relations, to report on conditions in their country. Over 1,500 persons responded, which allowed us to create indices of practices in ten broad areas for 33 countries. The GLS' focus on de facto labor practices contrasts with recent studies of de jure labor regulations (Botero et al., 2004) and with more limited efforts to measure labor practices as part of surveys of economic freedom (Fraser Institute) and competitiveness (World Economic Forum). Although our pool of respondents differs greatly from the conservative foundations and business leaders who contribute respectively to the Fraser Institute and World Economic Forum reports, the GLS and the labor market components of the economic freedom and competitiveness measures give similar pictures of labor practices across countries. This similarity across respondents with different economic interests and ideological perspectives suggests that they are all reporting on labor market realities in a relatively unbiased way. As a broad summary statement, the GLS shows that practices favorable to workers are more prevalent in countries with high levels of income per capita; are associated with less income inequality; are unrelated to aggregate growth rates; but are modestly positively associated with unemployment.

Host Country Financial Development and MNC Activity
We present evidence that the level of financial development in FDI recipient countries systematically aects the spatial distribution of multinational corporations' (MNCs) sales. Using detailed proprietary survey data collected by the Bureau of Economic Analysis (BEA) on US multinational activity abroad, we find that stronger financial development in the host country has a negative effect on the share of MNC affiliate sales that remain in the host country, indicating a reduced propensity towards horizontal FDI. Conversely, the share of affiliate sales that is re-exported to third-country destinations increases, suggesting an increased propensity towards export-platform FDI. We provide a three-country model with heterogenous firms that rationalizes these observations : More financially developed host countries foster entry by domestic firms, making the local market more competitive for MNC products. This leads MNCs to orient their affiliates away from servicing the local market towards third-country markets instead.
Formation of Lignans(-)-Secoisolariciresinol and (-)-Matairesinol with Forsythia intermedia Cell-Free Extracts
In vivo labeling experiments of Forsythia intermedia plant tissue with [8-(C-14)]- and [9,9-(2)H2,OC(2)H3]coniferyl alcohols revealed that the lignans, (-)-secoisolariciresinol and (-)-matairesinol, were derived from two coniferyl alcohol molecules; no evidence for the formation of the corresponding (+)-enantiomers was found. Administration of (+/-)-[Ar-(H-3)] secoisolariciresinols to excised shoots of F.intermedia resulted in a significant conversion into (-)-matairesinol; again, the (+)-antipode was not detected. Experiments using cell-free extracts of F.intermedia confirmed and extended these findings. In the presence of NAD(P)H and H2O2, the cell-free extracts catalyzed the formation of (-)- secoisolariciresinol, with either [8-(C-14)]- or [9,9-(2)H2,OC(2)H3]coniferyl alcohols as substrates. The (+)- enantiomer was not formed. Finally, when either (-)-[Ar-(H-3)] or (+/-)-[Ar-(H-2)]secoisolariciresinols were used as substrates, in the presence of NAD(P), only (-)- and not (+)-matairesinol formation occurred. The other antipode, (+)-secoisolariciresinol, did not serve as a substrate for the formation of either (+)- or (-)-matairesinol. Thus, in F.intermedia, the formation of the lignan, (-)-secoisolariciresinol, occurs under strict stereochemical control, in a reaction or reactions requiring NAD(P)H and H2O2 as cofactors. This stereoselectivity is retained in the subsequent conversion into (-)-matairesinol, since (+)-secoisolariciresinol is not a substrate. These are the first two enzymes to be discovered in lignan formation

"How to project customer retention" revisited: the role of duration dependence
Cohort-level retention rates typically increase over time, and the beta-geometric (BG) distribution has proven to be a robust model for capturing and projecting these patterns into the future. According to this model, the phenomenon of increasing cohort-level retention rates is purely due to cross-sectional heterogeneity; an individual customer’s propensity to churn does not change
over time. In this paper we present the beta-discrete-Weibull (BdW) distribution as an extension to the BG model, one that allows individual-level churn probabilities to increase or decrease over time. In addition to capturing the phenomenon of increasing cohort-level retention rates, this new model can also accommodate situations in which there is an initial dip in retention rates before they increase (i.e., a U-shaped cohort-level retention curve). A key finding is that
even when aggregate retention rates are monotonically increasing, the individual-level churn probabilities are unlikely to be declining over time, as conventional wisdom would suggest. We carefully explore these connections between heterogeneity, duration dependence, and the shape of the retention curve, and draw some managerially relevant conclusions, e.g., that accounting for cross-sectional heterogeneity is more important than accounting for any individual-level dynamics in churn propensities
Excitation and decay of projectile-like fragments formed in dissipative peripheral collisions at intermediate energies
Projectile-like fragments (PLF:15<=Z<=46) formed in peripheral and
mid-peripheral collisions of 114Cd projectiles with 92Mo nuclei at E/A=50 MeV
have been detected at very forward angles, 2.1 deg.<=theta_lab<=4.2 deg.
Calorimetric analysis of the charged particles observed in coincidence with the
PLF reveals that the excitation of the primary PLF is strongly related to its
velocity damping. Furthermore, for a given V_PLF*, its excitation is not
related to its size, Z_PLF*. For the largest velocity damping, the excitation
energy attained is large, approximately commensurate with a system at the
limiting temperatureComment: 5 pages, 6 figure
Acute experimental glomerulonephritis induced by the glomerular deposition of circulating polymerid IgA-Concanavalin A complexes
The perfusion of polymeric or secretory IgA-Concanavalin A complexes into the aorta of rats led to a mannose-dependent binding of both IgA and lectin to the glomerular capillary wall, as shown by double immunolocalization experiments, by quantitative analysis of the amount of radiolabeled complexes bound per g of kidney, and by blocking experiments with the corresponding carbohydrate. Rats injected with amounts of those complexes as low as 500 ?g developed, one hour later, a focal and segmental proliferative glomerulonephritis characterized by the deposition of injected complexes and of rat C3 and rat fibrin/ fibrinogen in most glomeruli ; focal thrombosis and small areas of necrosis in 10 to 15% of glomeruli, confined to the periphery of a single lobule of the tuft and segmental infiltration of these glomeruli by polymorphonuclear leucocytes and platelets. At the same time, many mesangial cells exhibited a hyperactive appearance, and red blood cells were noted in tubular lumens. In contrast, rats similarly injected with either monomeric IgA-ConA complexes, multimeric or secretory IgA-peanut agglutinin complexes or polymeric or monomeric IgA aggregates of comparable apparent molecular weight did not develop obvious glomerular lesions within one hour. The data indicate that preformed polymeric IgA-ConA complexes can specifically bind to glomerular structures in vivo and trigger acute glomerular lesions locally, analogous to those observed in some glomerular diseases associated with a cryoglobulinemia

Fragment Isospin as a Probe of Heavy-Ion Collisions
Isotope ratios of fragments produced at mid-rapidity in peripheral and
central collisions of 114Cd ions with 92Mo and 98Mo target nuclei at E/A = 50
MeV are compared. Neutron-rich isotopes are preferentially produced in central
collisions as compared to peripheral collisions. The influence of the size (A),
density, N/Z, E*/A, and Eflow/A of the emitting source on the measured isotope
ratios was explored by comparison with a statistical model (SMM). The
mid-rapidity region associated with peripheral collisions does not appear to be
neutron-enriched relative to central collisions.Comment: 12 pages including figure
