What Happens to Wages After Displacement?

Faced with limited resources, policymakers need to know when and where to target support for displaced workers. The academic literature offers little support, presenting wide-ranging results with no consistent explanation for the observed differences in wages after workers are displaced. In this paper, we demonstrate that the heterogeneity found in the literature is consistent with varying market conditions. The results suggest that support for displaced workers can be more efficiently allocated by considering the timing and location of displacement.Displaced Workers; Mexico

Mexican employment dynamics : evidence from matched firm-worker data

Using a census of all workers in private establishments in the formal sector in Mexico to track workers and establishments over time, this paper presents the first Mexican worker and job flow statistics. The data allow for comparing these flows across time, space, and worker characteristics. Although many patterns are similar to those documented in developing countries, the analysis uncovers patterns that have potentially important policy implications. The authors compare the results to the literature, illustrate how the statistics change during times of reform and crisis, and present novel findings that contribute to the broader literature on worker reallocations.Labor Markets,Microfinance,Labor Policies,Access to Finance,E-Business

Developing Capacity, Skills, and Tobacco Control Networks to address Tobacco-related Disparities: Leadership and Advocacy Institute to Advance Minnesota’s Parity for Priority Populations (LAAMPP)

Priority populations disproportionately experience tobacco-related disparities, despite population level declines in tobacco use. The Leadership and Advocacy Institute to Advance Minnesota’s Parity for Priority Populations (LAAMPP) recruits and trains African immigrants/African Americans, Asian Americans/Pacific Islanders, American Indians, Chicano/Latinos, and LGBTQ community members to develop leaders to address tobacco harms in their communities. This paper describes and evaluates the LAAMPP Institute, and discusses lessons learned through the Institute and future directions for community-based tobacco-control efforts. The mixed-methods evaluation included qualitative key informant interviews with LAAMPP Fellows and community and project contacts, a Skills Assessment Tool, project case studies, and a social network analysis of the Fellows’ tobacco-control social networks at baseline and follow-up. At follow-up, Fellows’ tobacco control networks were larger, more extensive and diverse, and included more actors perceived to be influential in tobacco control. Fellows’ skills increased in core competencies (tobacco control, advocacy, facilitation, collaboration, cultural/community competence) and Fellows used tobacco, advocacy and cultural/community competencies more frequently. Four of five cohorts successfully passed policies. The results of LAAMPP suggest that a cross-cultural leadership institute contributes to the successful development of capacity and leadership skills among priority populations and may be a useful model for others working toward health equity

Use of multiple singular value decompositions to analyze complex intracellular calcium ion signals

We compare calcium ion signaling ($\mathrm {Ca}^{2+}$) between two exposures; the data are present as movies, or, more prosaically, time series of images. This paper describes novel uses of singular value decompositions (SVD) and weighted versions of them (WSVD) to extract the signals from such movies, in a way that is semi-automatic and tuned closely to the actual data and their many complexities. These complexities include the following. First, the images themselves are of no interest: all interest focuses on the behavior of individual cells across time, and thus, the cells need to be segmented in an automated manner. Second, the cells themselves have 100$+$ pixels, so that they form 100$+$ curves measured over time, so that data compression is required to extract the features of these curves. Third, some of the pixels in some of the cells are subject to image saturation due to bit depth limits, and this saturation needs to be accounted for if one is to normalize the images in a reasonably unbiased manner. Finally, the $\mathrm {Ca}^{2+}$ signals have oscillations or waves that vary with time and these signals need to be extracted. Thus, our aim is to show how to use multiple weighted and standard singular value decompositions to detect, extract and clarify the $\mathrm {Ca}^{2+}$ signals. Our signal extraction methods then lead to simple although finely focused statistical methods to compare $\mathrm {Ca}^{2+}$ signals across experimental conditions.Comment: Published in at http://dx.doi.org/10.1214/09-AOAS253 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

Awareness and Practices on Handwashing and the Use of Mask Among Non-Allied Health Students: A Basis for Health Promotion

The use of masks for the protection against COVID-19 infections has been very common in the year 2020. However, there is little to no literature regarding this concept. The aim of the study was to identify the level of awareness and practices in the use of masks and as well as to determine if the relationship exists between the variables. A descriptive-evaluative, descriptive-comparative, and descriptive- correlational research design was used in this study. One hundred non-allied health students were chosen to participate in this study using the purposive sampling technique. The results revealed that awareness of the respondents on handwashing and its use is high. It also shows that there is a high level of practice on handwashing and the use of masks. The respondents’ perception of the use of masks and handwashing practices showed a significant positive relationship between the awareness of the use of masks and practice on handwashing. There was no significant difference found in the level of awareness and practices on handwashing when grouped according to sex, year level, colleges, and family income. However, a significant difference was found in the awareness level when grouped according to age and also in practices on the use of masks when grouped according to sex and the college they belong to.

Do all raindrops fall at terminal speed?

A unique relation between raindrop size and fall speed vt(D) is assumed throughout atmospheric science. Yet, our speed versus size measurements of millions of drops during natural rainfall events show that many intermediate sized raindrops fall up to an order of magnitude faster than expected. Furthermore, images of drop clusters reveal that these “super‐terminal drops” are differently sized fragments of a recent break‐up, moving with the speed of the parent drop and relaxing towards vt(D). Additional evidence of the break‐up conjecture includes: (i) positive skewness in the distribution of fall speed deviations, (ii) strong size dependence of fall speed deviations and their maximum values and, (iii) preponderance of super‐terminal drops in the presence of large raindrops (i.e., during periods of high rainfall rates)
