The KArlsruhe TRItium Neutrino (KATRIN) experiment, which aims to make a direct and model-independent determination of the absolute neutrino mass scale, is a complex experiment with many components. More than 15 years ago, we published a technical design report (TDR) [https://publikationen.bibliothek.kit.edu/270060419] to describe the hardware design and requirements to achieve our sensitivity goal of 0.2 eV at 90% C.L. on the neutrino mass. Since then there has been considerable progress, culminating in the publication of first neutrino mass results with the entire beamline operating [arXiv:1909.06048]. In this paper, we document the current state of all completed beamline components (as of the first neutrino mass measurement campaign), demonstrate our ability to reliably and stably control them over long times, and present details on their respective commissioning campaigns., Comment: Added missing acknowledgement, corrected performance statement in chapter 4.2.5, updated author list and references

Physics - Instrumentation and Detectors - Abstract
The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to determine the effective electron (anti)neutrino mass with a sensitivity of $0.2\textrm{ eV/c}^2$ (90$\%$ C.L.) by precisely measuring the endpoint region of the tritium $\beta$-decay spectrum. It uses a tandem of electrostatic spectrometers working as MAC-E (magnetic adiabatic collimation combined with an electrostatic) filters. In the space between the pre-spectrometer and the main spectrometer, an unavoidable Penning trap is created when the superconducting magnet between the two spectrometers, biased at their respective nominal potentials, is energized. The electrons accumulated in this trap can lead to discharges, which create additional background electrons and endanger the spectrometer and detector section downstream. To counteract this problem, "electron catchers" were installed in the beamline inside the magnet bore between the two spectrometers. These catchers can be moved across the magnetic-flux tube and intercept on a sub-ms time scale the stored electrons along their magnetron motion paths. In this paper, we report on the design and the successful commissioning of the electron catchers and present results on their efficiency in reducing the experimental background., Comment: - 12 pages, 14 figures, LaTeX; typos corrected, references added; precised a few arguments, added additional discussions, results unchanged

We report on the neutrino mass measurement result from the first four-week science run of the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from a high-purity gaseous molecular tritium source are energy analyzed by a high-resolution MAC-E filter. A fit of the integrated electron spectrum over a narrow interval around the kinematic endpoint at 18.57 keV gives an effective neutrino mass square value of $(-1.0^{+0.9}_{-1.1})$ eV$^2$. From this we derive an upper limit of 1.1 eV (90$\%$ confidence level) on the absolute mass scale of neutrinos. This value coincides with the KATRIN sensitivity. It improves upon previous mass limits from kinematic measurements by almost a factor of two and provides model-independent input to cosmological studies of structure formation.

Sterile neutrinos in the keV mass range present a viable candidate for dark matter. They can be detected through single β -decay, where they cause small spectral distortions. The Karlsruhe Tritium Neutrino (KATRIN) experiment aims to search for keV-scale sterile neutrinos with high sensitivity. To achieve this, the KATRIN beamline will be equipped with a novel multi-pixel silicon drift detector focal plane array named TRISTAN. In this study, we present the performance of a TRISTAN detector module, a component of the eventual 9-module system. Our investigation encompasses spectroscopic aspects such as noise performance, energy resolution, linearity, and stability. [ABSTRACT FROM AUTHOR]

- Abstract
Apparently, the department of agriculture is the last bastion for ideological pluralism in the modern American academy. Almost everywhere else, according to research by Stanley Rothman et al., a monolithic liberal orthodoxy holds sway, rewarding its own and conferring career disadvantage upon scholars deemed politically inconvenient. As his acceptance address for the NAS's highest award, Professor Rothman proffers statistical corroboration, from his team's survey analyses, of the anecdotal impression that many who aspire to the centers of intellectual curiosity are excluded simply for thinking different thoughts. (Contains 17 notes and 4 tables.)

- Abstract
This assessment of the climate of racial and ethnic attitudes in Howard Beach (New York) was conducted at John Adams High School, the public school attended by the greatest number of high school children in the Howard Beach community. The survey of 1,217 students was administered in December, 1986, several weeks before the incident in which a number of Blacks were beaten and one died in Howard Beach. Results of the survey revealed a significant amount of racial and ethnic tolerance as well as tensions. Large majorities of all White groups reported that neither they nor their parents discouraged contacts with non-Whites. While students report a high perception of tolerance in their home environment, in school many students perceived the existence of racial and ethnic problems. The schools' three largest minority groups--Italians, Blacks, and Hispanics--elicited the highest rates of negative stereotyping. Findings demonstrated the complexity of prejudice. There was no consistent pattern of racial cleavage. (PS)

- Abstract
Uses content analysis of television characters in all occupations across 30 seasons to test the argument that television entertainment depicts business negatively. Reaffirms that television stigmatizes the occupation of business, independently of economic factors. Notes that these results pose a challenge to mass communications theory that interprets popular culture as a source of social control. (SR)

The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to measure the effective electron anti-neutrino mass with an unprecedented sensitivity of $0.2\,\mathrm{eV}/\mathrm{c}^2$, using $\beta$-electrons from tritium decay. The electrons are guided magnetically by a system of superconducting magnets through a vacuum beamline from the windowless gaseous tritium source through differential and cryogenic pumping sections to a high resolution spectrometer and a segmented silicon pin detector. At the same time tritium gas has to be prevented from entering the spectrometer. Therefore, the pumping sections have to reduce the tritium flow by more than 14 orders of magnitude. This paper describes the measurement of the reduction factor of the differential pumping section performed with high purity tritium gas during the first measurement campaigns of the KATRIN experiment. The reduction factor results are compared with previously performed simulations, as well as the stringent requirements of the KATRIN experiment., Comment: 19 pages, 4 figures, submitted to Vacuum

Content analysis of front page New York Times stories during the first and second years of the Barack Obama presidency revealed news coverage that was far more positive in tone than the norm for recent U.S. presidents, particularly with respect to foreign policy coverage. While coverage of Obama was somewhat less positive during 2010 when compared to 2009, the Obama findings overall reveal a much longer honeymoon than seen in the past. Coverage of specific problematic policy areas, like offshore drilling issues in the wake of the BP oil spill, was particularly negative. Coverage of arms control matters was very positive in tone in 2010 for Obama, who won the Nobel Peace Prize in 2009. Keywords: Political Communications, Political News Coverage, New York Times, Barack Obama, Presidential Honeymoon, Press-Presidential Relations. Durante los primeros dos anos de su presidencia Barack Obama gozo de una cobertura muy positiva comparada con la de sus antecesores en sus respectivos primeros bienios. Esto es lo que destaca un analisis de contenido de primeras planas del New York Times que comprende el periodo mencionado. A pesar de que el ano 2010 (segundo ano) fue menos positivo que 2009, el analisis de contenido revela que la presidencia de Obama se distingue de la de sus antecesores por haber logrado la luna de miel mas prolongada con la opinion publica. La cobertura de areas problematicas de politicas como la perforacion de pozos marinos en la etapa inicial del derrame de BP en el Golfo de Mexico fue particularmente negativa. En contraste, la cobertura de la politica de control de armas fue muy positiva, como tambien lo fue el que Obama recibiera el Premio Nobel 2009., Barack Obama was the first president in years to enjoy a 'honeymoon' in the mass media during his first months in office (Farnsworth and Lichter 2006, 2011b, 2012).

Recently, Politics & Policy published an article presenting our findings that reveal President Barack Obama received something of a media honeymoon in The New York Times, a sharp contrast from that influential newspaper's first-year coverage of Reagan, Clinton, and George W. Bush. Our findings triggered a thoughtful column concerning political coverage by the Times' public editor, Arthur S. Brisbane, which in turn led to extensive online discussions of media bias. In the interest of continuing this discussion and encouraging more substantive, even-handed, and informative news in the ongoing presidential campaign, this short response offers suggestions about what we regard as the two key problems of contemporary journalism: that the media are too focused on the sports of politics ('the horse-race') at the expense of issue-based coverage, and that media outlets sometimes play favorites in the tone of coverage. Keywords: Presidential News Coverage, Political Communications, Media, Parties, Elections, Voting, Political Institutions, 2012 Presidential Campaign, Barack Obama. Recientemente, Politics & Policy publico un articulo presentando resultados nuestros que revelan que el presidente Barak Obama recibio una especie de luna de miel en el periodico The New York Times, mostrando un gran contraste en la cobertura del primer ano de Reagan, Clinton y George W. Bush. Nuestros resultados provocaron una nota editorial reflexiva por parte del editor publico del Times Arthur S. Brisbane, quien a su vez desencadeno extensas discusiones en linea sobre la imparcialidad de los medios de comunicacion. Con el interes de continuar esta discusion y fomentar noticias mas sustanciales, imparciales e informativas en la actual campana presidencial, este breve ensayo ofrece sugerencias respecto a lo que consideramos los dos problemas clave del periodismo contemporaneo: que los medios estan muy enfocados en el deporte de la politica (o 'the horse-race') a expensas de reportajes basados en problemas y que los medios de comunicacion algunas veces muestran un tono de favoritismo en sus coberturas., As reporters and editors cover the 2012 general election, we would all be better off if they try to improve news content over that provided four years ago. Even though [...]
