Euro-Productivity and Euro-Jobs since the 1960s: Which Institutions Really Mattered?
How have labor market institutions and welfare-state transfers affected jobs and productivity in Western Europe, relative to industrialized Pacific Rim countries? Orthodox criticisms of European government institutions are right in some cases and wrong in others. Protectionist labor-market policies such as employee protection laws seem to have become more costly since about 1980, not through overall employment effects, but through the net human-capital cost of protecting senior male workers at the expense of women and youth. Product-market regulations in core sectors may also have reduced GDP, though here the evidence is less robust. By contrast, high general tax levels have shed the negative influence they might have had in the 1960s and 1970s. Similarly, other institutions closer to the core of the welfare state have caused no net harm to European jobs and growth. The welfare state%u2019s tax-based social transfers and coordinated wage bargaining have not harmed either employment or GDP. Even unemployment benefits do not have robustly negative effects.

Natural aging and reversion behavior of Al-Cu-Li-Ag-Mg alloy Weldalite (tm) 049
This study was initiated to understand the natural aging and reversion behavior of Weldalite (trademark) 049 in tempers without cold work. Of particular interest are: (1) the microstructural basis for the high strength in the T4 condition; (2) an explanation of the reversion phenomenon; and (3) the effect of re-aging at room temperature after a reversion treatment. Mechanical properties were measured and transmission electron microscopy (TEM) analysis performed at various stages of microstructural development during aging, reversion, and subsequent re-aging
Structure and properties during aging of an Al-Cu-Li-Ag-Mg alloy, Weldalite (tm) 049
An Al-Cu-Li-Ag-Mg alloy, Weldalite (trademark) 049, was recently introduced as an ultra-high strength alloy (7000 MPa yield strength in artificially aged tempers) with good weldability. In addition, the alloy exhibits an extraordinary natural aging response (440 MPa yield strength (YS) in the unstretch condition) and a high ductility reversion condition which may be useful as a cold-forming temper. In contrast to other Al-Li alloys, these properties can essentially be obtained with or without a stretch or other coldworking operation prior to aging. Preliminary studies have revealed that the T4 temper (no stretch, natural age) is strengthened by a combination of GP zones and delta prime (Al3Li). The T6 temper (no stretch, aged at 180 C to peak strength) was reported to be strengthened primarily by T(sub 1) phase (Al2CuLi) with a minor presence of a theta prime like (Al2Cu) phase. On the other hand, a similar but lower solute containing alloy was reported to contain omega, (stoichiometry unknown), theta prime, and S prime in the peak strength condition. The purpose of this study is to further elucidate the strengthening phases in Weldalite (trademark) 049 in the unstretched tempers, and to follow the development of the microstructure from the T4 temper through reversion (180 C for 5 to 45 minutes) to the T6 temper
The 2018 public consultation on standardized packaging in Singapore: Analysis of policy actors\u27 submissions
After a public consultation in 2018, Singapore implemented standardized tobacco packaging as part of its portfolio of tobacco control policies in 2020, in compliance with Article 11 guidelines for implementing the World Health Organization Framework Convention on Tobacco Control. This study analyzed policy actors in opposition to standardized packaging in Singapore and their submissions to the public consultation. Policy actors were profiled, and their arguments were then coded and compared across submissions. Descriptive results were then summarized in a narrative synthesis. In total, 79 submissions were considered for final analysis that opposed plain packaging in Singapore. Thematic analysis shows that transnational tobacco companies and their subsidiaries in Singapore, along with a variety of policy actors opposed to the standardized packaging policy, have significant similarities in arguments, often with identical statements. Industry tactics included framing tobacco as a trade and investment issue; utilizing trade barriers, intellectual property, and investment rights; pursuing litigation or threat of litigation; mobilizing third-party support and citing policy failure. This study provides evidence that further contributes to the growing literature on commercial determinants of health particularly industry tactics and, in this case, where the tobacco industry and its local and global allies, utilize to counter evidence-based tobacco control measures

Lower critical field measurements in YBa2Cu3O(6+x) single crystals
The temperature dependence of the lower critical field in YBa2Cu3O(6+x) single crystals was determined by magnetization measurements with the applied field parallel and perpendicular to the c-axis. Results are compared with data from the literature and fitted to Ginzberg-Landau equations by assuming a linear dependence of the parameter kappa on temperature. A value of 7 plus or minus 2 kOe was estimated for the thermodynamic critical field at T = O by comparison of calculated H (sub c2) values with experimental data from the literature
Measurement of H(sub c1) in a single crystal of YBa2Cu3O7 with low pinning
The measurement of H(sub c1) in barium yttrium copper oxide (BYCO) is often ambiguous because the presence of large pinning forces makes it difficult to discern exactly where the first deviation from linearity occurs. In addition there are complications because demagnetizing factors are often not well known. By utilizing a single crystal of YBCO with a nearly cubic shape, the uncertainty in the demagnetizing factor was minimized. In addition, the crystal used exhibited a very small amount of pinning with H applied perpendicular to the c axis, and a sharp break in the initial magnetization vs. field curve could be observed over a wide range of temperature. This allowed a precise determination of H(sub c1). The measured values of H(sub c1) could be well described by the Abrikosov relation with a Ginzburg-Landau parameter which varied linearly with temperature
The effect of moving on union dissolution
This paper examines the effect of migration and residential mobility on union dissolution among married and cohabiting couples. While there is a large, multi-disciplinary literature looking at the determinants of union dissolution in Europe and North America, the possible impact of geographical mobility has received little attention. This is despite the fact that moving is a stressful life event and that numerous studies suggest that women’s economic well-being and employment suffer from family moves which are usually stimulated by the man’s career. We base our longitudinal analysis on retrospective event-history data from Austria and apply hazard regression. Our results show that couples who move frequently have a significantly higher risk of union dissolution. We argue that frequent moving increases couple stress and union instability through a variety of mechanisms.Austria, dissolution of marriage, event history analysis, internal migration, residential mobility
