Unions and Upward Mobility for Asian American and Pacific Islander Workers

Asian Americans and Pacific Islanders (AAPIs) are, with Latinos, the fastest growing ethnic group in the U.S. workforce. In 2009, Asian American and Pacific Islanders were one of every 20 U.S. workers, up from one in 40 only 20 years earlier. AAPIs, again with Latinos, are also the fastest growing ethnic group in organized labor, accounting for just under one-in-20 unionized workers in 2009. Even after controlling for workers' characteristics including age, education level, industry, and state, unionized AAPI workers earn about 14.3 percent more than non-unionized AAPI workers with similar characteristics. This translates to about $2.50 per hour more for unionized AAPI workers. Unionized AAPI workers are also about 16 percentage points more likely to have health insurance and about 22 percentage points more likely to have a retirement plan than their non-union counterparts. The advantages of unionization are greatest for AAPI workers in the 15 lowest-paying occupations. Unionized AAPI workers in these low-wage occupations earn about 20.1 percent more than AAPI workers with identical characteristics in the same generally low-wage occupations. Unionized AAPI workers in low-wage occupations are also about 23.2 percentage points more likely to have employer-provided health insurance and 26.3 percentage points more likely to have a retirement plan through their job

Unions and Upward Mobility for Asian Pacific American Workers

Asian Pacific American (APA) workers are, with Latinos, the fastest growing group in the U.S. workforce and in organized labor. Since the late 1980s, APA workers have seen their representation in the ranks of U.S. unions almost double, from about 2.5 percent of all union workers in 1989 to about 4.6 percent in 2008.This report uses national data from the Current Population Survey (CPS) to show that unionization raises the wages of the typical APA worker by 9 percent compared to their non-union peers. The study goes on to show that unionization also increases the likelihood that an APA worker will have health insurance and a pension

Diversity and Change: Asian American and Pacific Islander Workers

About 7.4 million Asian Americans and Pacific Islanders (AAPI) work in the United States, making up 5.3 percent of the total U.S. workforce. About 7.1 million of these AAPI workers are Asian Americans; about 300,000 are Pacific Islanders. The AAPI workforce is almost 20 times larger today than it was in 1960. Meanwhile, the share of AAPIs in the total workforce has increased about tenfold over the same period. Three broad themes emerge from our analysis of the data: The first is that AAPI workers are highly diverse. The second theme is that AAPI workers face many challenges in the labor market. The final theme is that the trends in the economic circumstances of AAPI workers have closely mirrored those of the broader workforce.unions, wages, benefits, pension, health insurance, asian

Dark Chocolate (70% Cacao) Modulates Gamma Wave Frequencies in Vigorously Active Individuals

Background: Visualization and the demand to increase cognitive function to improve performance is an area of growing interest in athletes and physically active individuals. Gamma (25-45 Hz) waves, the fastest of the brainwave frequencies, are optimal for cognitive function. Objective: Determine if savoring and ingestion of dark chocolate (70% cacao) can modulate gamma wave frequencies between visualization at a state of rest and a state of exercise performance in vigorously active individuals. Participants/setting: The study recruited 10 vigorously active individuals from Loma Linda University. Participants’ mean age was 23.7± 2.2 years. Vigorous activity was defined by the Centers for Disease Control and America College of Sports Medicine. Intervention: Participant visualization of rest and exercise were assessed by EEG Power Spectral Density (PSD) during three 60-second trials: without cacao (1.4 g of 70% cacao) consumption, savoring cacao, and after fully ingesting cacao. EEG wave band activity was recorded from 9 cerebral cortical scalp locations. Statistical analyses performed: Z-scores, using a reference baseline at visualization or rest without cacao were utilized. Results: During visualization of rest, there was a significant increase of 541.5% in gamma wave frequency when comparing no cacao to savoring cacao (p=\u3c.001). During exercise visualization, there was a significant increase of 207.5% in gamma wave frequency when comparing no cacao to savoring cacao (p=\u3c.001). Z-score PSD of overall gamma wave frequencies were lowest in the absence of cacao during rest and exercise respectively (.32, .75). During visualization of rest, there was a significant decrease of 58.0% in gamma waves when comparing savoring cacao to fully ingesting cacao (p=\u3c.001). Conclusions: We suggest that EEG gamma waves are heightened during savoring and ingestion of 1.4 g of cacao, when visualization of rest and exercise take place

Predicting Second and Third Graders' Reading Comprehension Gains: Observing Students' and Classmates Talk during Literacy Instruction using COLT.

This paper introduces a new observation system that is designed to investigate students' and teachers' talk during literacy instruction, Creating Opportunities to Learn from Text (COLT). Using video-recorded observations of 2nd-3rd grade literacy instruction (N=51 classrooms, 337 students, 151 observations), we found that nine types of student talk ranged from using non-verbal gestures to generating new ideas. The more a student talked, the greater were his/her reading comprehension (RC) gains. Classmate talk also predicted RC outcomes (total effect size=0.27). We found that 11 types of teacher talk ranged from asking simple questions to encouraging students' thinking and reasoning. Teacher talk predicted student talk but did not predict students' RC gains directly. Findings highlight the importance of each student's discourse during literacy instruction, how classmates' talk contributes to the learning environments that each student experiences, and how this affects RC gains, with implications for improving the effectiveness of literacy instruction

Approximation Algorithms and Hardness for nn-Pairs Shortest Paths and All-Nodes Shortest Cycles

We study the approximability of two related problems on graphs with $n$ nodes and $m$ edges: $n$-Pairs Shortest Paths ($n$-PSP), where the goal is to find a shortest path between $O(n)$ prespecified pairs, and All Node Shortest Cycles (ANSC), where the goal is to find the shortest cycle passing through each node. Approximate $n$-PSP has been previously studied, mostly in the context of distance oracles. We ask the question of whether approximate $n$-PSP can be solved faster than by using distance oracles or All Pair Shortest Paths (APSP). ANSC has also been studied previously, but only in terms of exact algorithms, rather than approximation. We provide a thorough study of the approximability of $n$-PSP and ANSC, providing a wide array of algorithms and conditional lower bounds that trade off between running time and approximation ratio. A highlight of our conditional lower bounds results is that for any integer $k\ge 1$, under the combinatorial $4k$-clique hypothesis, there is no combinatorial algorithm for unweighted undirected $n$-PSP with approximation ratio better than $1+1/k$ that runs in $O(m^{2-2/(k+1)}n^{1/(k+1)-\epsilon})$ time. This nearly matches an upper bound implied by the result of Agarwal (2014). A highlight of our algorithmic results is that one can solve both $n$-PSP and ANSC in $\tilde O(m+ n^{3/2+\epsilon})$ time with approximation factor $2+\epsilon$ (and additive error that is function of $\epsilon$), for any constant $\epsilon>0$. For $n$-PSP, our conditional lower bounds imply that this approximation ratio is nearly optimal for any subquadratic-time combinatorial algorithm. We further extend these algorithms for $n$-PSP and ANSC to obtain a time/accuracy trade-off that includes near-linear time algorithms.Comment: Abstract truncated to meet arXiv requirement.

Inactivation of the MDM2 RING domain enhances p53 transcriptional activity in mice

The MDM2 RING domain harbors E3 ubiquitin ligase activity critical for regulating the degradation of tumor suppressor p53, which controls many cellular pathways. The MDM2 RING domain also is required for an interaction with MDMX. Mice containing a substitution in the MDM2 RING domain, MDM2C462A, disrupting MDM2 E3 function and the MDMX interaction, die during early embryogenesis that can be rescued by p53 deletion. To investigate whether MDM2C462A, which retains p53 binding, has p53-suppressing activity, we generated Mdm2C462A/C462A;p53ER/- mice, in which we replaced the endogenous p53 alleles with an inducible p53ER/- allele, and compared survival with that of similarly generated Mdm2-/-;p53ER/- mice. Adult Mdm2-null mice died ~7 days after tamoxifen-induced p53 activation, indicating that in the absence of MDM2, MDMX cannot suppress p53. Surprisingly, Mdm2C462A/C462A;p53ER/- mice died ~5 days after tamoxifen injection, suggesting that p53 activity is higher in the presence of MDM2C462A than in the absence of MDM2. Indeed, in MDM2C462A-expressing mouse tissues and embryonic fibroblasts, p53 exhibited higher transcriptional activity than in those expressing no MDM2 or no MDM2 and MDMX. This observation indicated that MDM2C462A not only is unable to suppress p53 but may have gained the ability to enhance p53 activity. We also found that p53 acetylation, a measure of p53 transcriptional activity, was higher in the presence of MDM2C462A than in the absence of MDM2. These results reveal an unexpected role of MDM2C462A in enhancing p53 activity and suggest the possibility that compounds targeting MDM2 RING domain function could produce even more robust p53 activation
