The Resurgence of Nativism in California? The Case of Proposition 187 and Illegal Immigration
Theory: We argue that support among California voters for Proposition 187 in 1994 was an example of cyclical nativism. This nativism was provoked primarily by California's economic downturn during the early 1990s.
Hypotheses: We develop four specific hypotheses to explain how poor economic conditions in California and the consequent nativistic sentiments would result in support for Proposition 187:
1. voters who believe that California's economic condition is poor will be more likely to support Proposition 187;
2. voters who perceive themselves as being economically threatened by illegal immigrants will be more likely to support Proposition 187;
3. voters with lower levels of education are more economically vulnerable and will be more likely to support Proposition 187;
4. voters in Southern California feel more directly affected by illegal immigration and will be more likely to support Proposition 187.
Methods: To test these hypotheses, we analyze voter exit poll data from the 1994 California election. We utilize a two-stage probit model to allow for the endogeneity which results from the politicization of illegal immigration during this election.
Results: We find support for our hypotheses in the data. These findings cause us to conclude that nativism, fueled by economic conditions, was a salient factor leading many Californians to support Proposition 187
Awakening a sleeping giant: The riddle of Latino political participation
For some time now, the Latino voice has been gradually gaining strength in
American politics, particularly in such states as California, Florida, Illinois, New
York, and Texas, where large numbers of Latino immigrants have settled and
large numbers of electoral votes are at stake. Yet the issues public officials in
these states espouse and the laws they enact often do not coincide with the
interests and preferences of Latinos. The fact that Latinos in California and
elsewhere have not been able to influence the political agenda in a way that is
commensurate with their numbers may reflect their failure to participate fully in
the political process by first registering to vote and then consistently turning out
on election day to cast their ballots.
To understand Latino voting behavior, I first examine Latino political
participation in California during the ten general elections of the 1980s and
1990s, seeking to understand what percentage of the eligible Latino population
registers to vote, with what political party they register, how many registered
Latinos to go the polls on election day, and what factors might increase their
participation in politics. To ensure that my findings are not unique to California, I
also consider Latino voter registration and turnout in Texas for the five general
elections of the 1990s and compare these results with my California findings.
I offer a new approach to studying Latino political participation in which I
rely on county-level aggregate data, rather than on individual survey data, and employ the ecological inference method of generalized bounds. I calculate and
compare Latino and white voting-age populations, registration rates, turnout
rates, and party affiliation rates for California's fifty-eight counties. Then, in a
secondary grouped logit analysis, I consider the factors that influence these
Latino and white registration, turnout, and party affiliation rates.
I find that California Latinos register and turn out at substantially lower
rates than do whites and that these rates are more volatile than those of whites. I
find that Latino registration is motivated predominantly by age and education,
with older and more educated Latinos being more likely to register. Motor voter
legislation, which was passed to ease and simplify the registration process, has
not encouraged Latino registration . I find that turnout among California's Latino
voters is influenced primarily by issues, income, educational attainment, and the
size of the Spanish-speaking communities in which they reside. Although
language skills may be an obstacle to political participation for an individual, the
number of Spanish-speaking households in a community does not encourage or
discourage registration but may encourage turnout, suggesting that cultural and
linguistic assimilation may not be the entire answer.
With regard to party identification, I find that Democrats can expect a
steady Latino political identification rate between 50 and 60 percent, while
Republicans attract 20 to 30 percent of Latino registrants. I find that education
and income are the dominant factors in determining Latino political party
identification, which appears to be no more volatile than that of the larger
electorate.
Next, when I consider registration and turnout in Texas, I find that Latino
registration rates are nearly equal to those of whites but that Texas Latino
turnout rates are volatile and substantially lower than those of whites.
Low turnout rates among Latinos and the volatility of these rates may
explain why Latinos in California and Texas have had little influence on the
political agenda even though their numbers are large and increasing. Simply put,
the voices of Latinos are little heard in the halls of government because they do
not turn out consistently to cast their votes on election day.
While these findings suggest that there may not be any short-term or
quick fixes to Latino participation, they also suggest that Latinos should be
encouraged to participate more fully in the political process and that additional
education may be one means of achieving this goal. Candidates should speak
more directly to the issues that concern Latinos. Political parties should view
Latinos as crossover voters rather than as potential converts. In other words, if
Latinos were "a sleeping giant," they may now be a still-drowsy leviathan waiting
to be wooed by either party's persuasive political messages and relevant issues. </p
The Revolution Against Affirmative Action in California: Politics, Economics, and Proposition 209
We consider two possible explanations-economic anxiety and racial division for the appeal of Proposition 209 to California voters during the 1996 election. Voter support for this proposition has been attributed to racial differences in opinion and to economic anxiety caused by poor economic conditions in the state and the perceived threat that affirmative action presented in school admissions or the workplace. Because the presidential candidates campaigned on and debated the merits of affirmative action policy during this election, we incorporate this endogeneity into our analysis.
We develop two competing hypotheses to explain voter behavior: (1) if voters are blaming affirmative action for the state's economic conditions, then voters who believe that California's economic condition is poor or who perceive that their personal financial situation is worse will be more likely to support Proposition 209; and (2) if voters are, instead, divided along more traditional racial lines on the merits of affirmative action (winners versus losers), then whites, males, Republicans, and conservatives will be more likely to support Proposition 209, and other ethnic group members, females, Democrats, and liberals will be more likely to oppose Proposition 209.
To test these hypotheses, we analyze voter exit poll data from the 1996 California election. We utilize a two-stage logit model to allow for the endogeneity of candidate endorsements. We find support for the second of our two hypotheses. These findings cause us to conclude that racial division fueled by a fear of arbitrary exclusion prompted voter support for Proposition 209
Defining the critical hurdles in cancer immunotherapy
Scientific discoveries that provide strong evidence of antitumor effects in preclinical models often encounter significant delays before being tested in patients with cancer. While some of these delays have a scientific basis, others do not. We need to do better. Innovative strategies need to move into early stage clinical trials as quickly as it is safe, and if successful, these therapies should efficiently obtain regulatory approval and widespread clinical application. In late 2009 and 2010 the Society for Immunotherapy of Cancer (SITC), convened an "Immunotherapy Summit" with representatives from immunotherapy organizations representing Europe, Japan, China and North America to discuss collaborations to improve development and delivery of cancer immunotherapy. One of the concepts raised by SITC and defined as critical by all parties was the need to identify hurdles that impede effective translation of cancer immunotherapy. With consensus on these hurdles, international working groups could be developed to make recommendations vetted by the participating organizations. These recommendations could then be considered by regulatory bodies, governmental and private funding agencies, pharmaceutical companies and academic institutions to facilitate changes necessary to accelerate clinical translation of novel immune-based cancer therapies. The critical hurdles identified by representatives of the collaborating organizations, now organized as the World Immunotherapy Council, are presented and discussed in this report. Some of the identified hurdles impede all investigators; others hinder investigators only in certain regions or institutions or are more relevant to specific types of immunotherapy or first-in-humans studies. Each of these hurdles can significantly delay clinical translation of promising advances in immunotherapy yet if overcome, have the potential to improve outcomes of patients with cancer

Comprehensive molecular characterization of gastric adenocarcinoma
Gastric cancer is a leading cause of cancer deaths, but analysis of its molecular and clinical characteristics has been complicated by histological and aetiological heterogeneity. Here we describe a comprehensive molecular evaluation of 295 primary gastric adenocarcinomas as part of The Cancer Genome Atlas (TCGA) project. We propose a molecular classification dividing gastric cancer into four subtypes: tumours positive for Epstein–Barr virus, which display recurrent PIK3CA mutations, extreme DNA hypermethylation, and amplification of JAK2, CD274 (also known as PD-L1) and PDCD1LG2 (also knownasPD-L2); microsatellite unstable tumours, which show elevated mutation rates, including mutations of genes encoding targetable oncogenic signalling proteins; genomically stable tumours, which are enriched for the diffuse histological variant and mutations of RHOA or fusions involving RHO-family GTPase-activating proteins; and tumours with chromosomal instability, which show marked aneuploidy and focal amplification of receptor tyrosine kinases. Identification of these subtypes provides a roadmap for patient stratification and trials of targeted therapies
Creative destruction in science
Drawing on the concept of a gale of creative destruction in a capitalistic economy, we argue that initiatives to assess the robustness of findings in the organizational literature should aim to simultaneously test competing ideas operating in the same theoretical space. In other words, replication efforts should seek not just to support or question the original findings, but also to replace them with revised, stronger theories with greater explanatory power. Achieving this will typically require adding new measures, conditions, and subject populations to research designs, in order to carry out conceptual tests of multiple theories in addition to directly replicating the original findings. To illustrate the value of the creative destruction approach for theory pruning in organizational scholarship, we describe recent replication initiatives re-examining culture and work morality, working parents\u2019 reasoning about day care options, and gender discrimination in hiring decisions.
Significance statement
It is becoming increasingly clear that many, if not most, published research findings across scientific fields are not readily replicable when the same method is repeated. Although extremely valuable, failed replications risk leaving a theoretical void\u2014 reducing confidence the original theoretical prediction is true, but not replacing it with positive evidence in favor of an alternative theory. We introduce the creative destruction approach to replication, which combines theory pruning methods from the field of management with emerging best practices from the open science movement, with the aim of making replications as generative as possible. In effect, we advocate for a Replication 2.0 movement in which the goal shifts from checking on the reliability of past findings to actively engaging in competitive theory testing and theory building.

Comprehensive Pan-Genomic Characterization of Adrenocortical Carcinoma
SummaryWe describe a comprehensive genomic characterization of adrenocortical carcinoma (ACC). Using this dataset, we expand the catalogue of known ACC driver genes to include PRKAR1A, RPL22, TERF2, CCNE1, and NF1. Genome wide DNA copy-number analysis revealed frequent occurrence of massive DNA loss followed by whole-genome doubling (WGD), which was associated with aggressive clinical course, suggesting WGD is a hallmark of disease progression. Corroborating this hypothesis were increased TERT expression, decreased telomere length, and activation of cell-cycle programs. Integrated subtype analysis identified three ACC subtypes with distinct clinical outcome and molecular alterations which could be captured by a 68-CpG probe DNA-methylation signature, proposing a strategy for clinical stratification of patients based on molecular markers
Mechanical design of the optical modules intended for IceCube-Gen2
IceCube-Gen2 is an expansion of the IceCube neutrino observatory at the South Pole that aims to increase the sensitivity to high-energy neutrinos by an order of magnitude. To this end, about 10,000 new optical modules will be installed, instrumenting a fiducial volume of about 8 km3. Two newly developed optical module types increase IceCube’s current sensitivity per module by a factor of three by integrating 16 and 18 newly developed four-inch PMTs in specially designed 12.5-inch diameter pressure vessels. Both designs use conical silicone gel pads to optically couple the PMTs to the pressure vessel to increase photon collection efficiency. The outside portion of gel pads are pre-cast onto each PMT prior to integration, while the interiors are filled and cast after the PMT assemblies are installed in the pressure vessel via a pushing mechanism. This paper presents both the mechanical design, as well as the performance of prototype modules at high pressure (70 MPa) and low temperature (−40∘C), characteristic of the environment inside the South Pole ice
