    How Effective Are Unemployment Benefit Sanctions? Looking Beyond Unemployment Exit

    Get PDF
    This paper provides a comprehensive evaluation of benefit sanctions, i.e. temporary reductions in unemployment benefits as punishment for noncompliance with eligibility requirements. In addition to the effects on unemployment durations, we evaluate the effects on post-unemployment employment stability, on exits from the labor market and on earnings. In our analysis we use a rich set of Swiss register data which allow us to distinguish between ex ante effects, the effects of warnings and the effects of enforcement of benefit sanctions. Adopting a multivariate mixed proportional hazard approach to address selectivity, we find that both warnings and enforcement increase the job finding rate and the exit rate out of the labor force. Warnings do not affect subsequent employment stability but do reduce post-unemployment earnings. Actual benefit reductions lower the quality of post-unemployment jobs both in terms of job duration as well as in terms of earnings. The net effect of a benefit sanction on post-unemployment income is negative. Over a period of two years after leaving unemployment workers who got a benefit sanction imposed face a net income loss equivalent to 30 days of full pay due to the ex post effect. In addition to that, stricter monitoring may reduce net earnings by up to 4 days of pay for every unemployed worker due to the ex ante effect.unemployment duration, earnings effects, benefit sanctions, competing-risk duration models

    Measurements in merging flow

    Previous measurements of the velocity field in the vicinity of two intersecting submerged turbulent jets provided evidence that, contrary to the usual assumptions, intersecting flows may not necessarily be combined using vector addition of velocities or momentum flux densities. To gather additional experimental evidence on the details of the velocity field near the intersection of two submerged turbulent jets, this study measured time average velocity magnitudes and directions of two perpendicular intersecting axisymmetric submerged turbulent incompressible air jets of approximately equal strength. Because of the need to detect reverse flows, a three-dimensional pitot-type probe was used. This could sense yaw and pitch angles as well as velocity magnitudes. Two sets of measurements were taken. The more detailed set was confined to the plane of the nozzles, the less detailed set obtained cross-sectional data at four stations, three of these being in the observed reverse flow. The data show that the reverse flow spreads much more rapidly perpendicular to the nozzle plane than in the nozzle plane, whereas the forward flow is fairly symmetric. , Similarity profiles were found in both the forward and reverse flows. In the forward flow the distribution was essentially Gaussian. This was also true in the backward flow in the direction normal to the plane of the nozzles. In the plane of the nozzles the backward flow profiles were close to semi-elliptical or semi-circular, depending on the scales for plotting.U.S. Department of the InteriorU.S. Geological SurveyOpe

    Analysis Strategy Riau University Organization in Human Resource Development (a Case Study Development University Lecturers Riau)

    As educational staff in University of Riau (UR), a Lecturers has duty to implement the three of higher education responsibility. Particularly in teaching, a lecture must have education background . Infact, almost eductional background of lecturers in University of Riau are master degres (S2). To be a lecturer in University of Riau, a lecturer should be have doctoral degree (S3) in other to achieve vision and mission of the university and also society trust UR to study there. From the result can be obtained that the education development strategy to continue lecturers study is not did seriously. It can be indicated by their role to give information tranparently about scholarship fund from cooperation parties as DIKTI and Local Goverment of Riau Province. Another reason is no budget allocation to help lecturer to continue their study. We can take an example when the lecturer need a fund as tickets to go abroad and back. UR is not provide funds for it. Besides, there is no cooperation of units in UR to negotiated to improve lecturer education. What happens is partial that cause no place to coordinate each other, share,or making strong strategies to developped lecturer. UR has given a fund seriously for researcher to developt their self. There are many available grant for lecturer to do research, but it is need activeness and seriousness to submit their proposal. Here, there are competiton to obtain the grant research.

    Drug-Induced Pigmentation

    Get PDF
    Drug-induced pigmentation occurs in up to 20% of acquired pigmentary disorders of the skin. Association of its occurrence was reported in certain drugs, including alkylating/cytotoxic agents, analgesics, antiarrhythmics, anticoagulants, antiepileptics, antimalarials, antimicrobials, antiretrovirals, metals, prostaglandin analogs, and psychotropic agents, among others. Proposed mechanisms include (1) accumulation of melanin, (2) accumulation of drug, (3) generation of new pigment, and (4) deposition of iron. Though difficult to confirm the drug association, the history, with emphasis on currently used drugs, and clinical examination may guide practitioners to an accurate diagnosis. Treatment options include cessation of the drug, adequate sun protection, and non-ablative pigment lasers

    Structural insights into selectivity and cofactor binding in snake venom l-amino acid oxidases

    Abstractl-Amino acid oxidases (LAAOs) are flavoenzymes that catalytically deaminate l-amino acids to corresponding α-keto acids with the concomitant production of ammonia (NH3) and hydrogen peroxide (H2O2). Particularly, snake venom LAAOs have been attracted much attention due to their diverse clinical and biological effects, interfering on human coagulation factors and being cytotoxic against some pathogenic bacteria and Leishmania ssp. In this work, a new LAAO from Bothrops jararacussu venom (BjsuLAAO) was purified, functionally characterized and its structure determined by X-ray crystallography at 3.1Å resolution. BjsuLAAO showed high catalytic specificity for aromatic and aliphatic large side-chain amino acids. Comparative structural analysis with prokaryotic LAAOs, which exhibit low specificity, indicates the importance of the active-site volume in modulating enzyme selectivity. Surprisingly, the flavin adenine dinucleotide (FAD) cofactor was found in a different orientation canonically described for both prokaryotic and eukaryotic LAAOs. In this new conformational state, the adenosyl group is flipped towards the 62–71 loop, being stabilized by several hydrogen-bond interactions, which is equally stable to the classical binding mode

    The Integrative Effects of Board Diversity, Firm Reputation, and Innovation vis-a-vis Firm Performance

    Get PDF
    A plethora of worldwide study on board diversity and its relationship with firm performance had produced mixed results. Our study investigated not only from the board diversity perspective, but also examined the integrative web of firm reputation and innovation as well as the shareholder activism. We employed Smart PLS and SPSS to run the 105-sampled data and the statistical findings suggested that firm reputation does boost firm performance but not innovation, and also there is a positive correlation between board diversity and firm reputation. The findings further posit that shareholder activism does indeed affect diverse representation of the board. However, it does not agree that shareholder activism itself has a positive correlation with firm performance. This could be attributed to the views of top-level management, directors, and company secretaries, who are more familiar with the nuances of the board modus operandi and functions
