Nonrobustness of the carryover effects of small classes in project STAR by Sohn, Kitae

“…Separately for effective schools, schools other than effective schools, and ineffective schools, the academic achievement of students is regressed on variables indicating small class assignment, along with student characteristics and school-by-entry wave fixed effects. Findings: The carryover effects of CSR are not robust; they are driven mostly by effective schools, which account for at most a quarter of STAR schools. …”

The effect of the environment on the structure, morphology and star-formation history of intermediate-redshift galaxies by Kelkar, Kshitija, Gray, Meghan E., Aragón-Salamanca, Alfonso, Rudnick, Gregory, Milvang-Jensen, Bo, Jablonka, Pascale, Schrabback, Tim

“…These galaxies have smoother light distributions than their star-forming counterparts. We also find that while almost all field and cluster S0s appear undisturbed, there is a relatively small population of star-forming S0s in clusters but not in the field. …”

A multifrequency radio continuum study of the Magellanic Clouds - I. Overall structure and star formation rates by For, B., Staveley-Smith, L., Hurley-Walker, Natasha, Franzen, Thomas, Kapinska, A., Filipovic, M., Collier, J., Wu, C., Grieve, K., Callingham, J., Bell, M., Bernardi, G., Bowman, J., Briggs, F., Cappallo, R., Deshpande, A., Dwarakanath, K., Gaensler, B., Greenhill, L., Hancock, Paul, Hazelton, B., Hindson, L., Johnston-Hollitt, M., Kaplan, D., Lenc, E., Lonsdale, C., McKinley, B., McWhirter, S., Mitchell, D., Morales, M., Morgan, E., Morgan, John, Oberoi, D., Offringa, A., Ord, S., Prabu, T., Procopio, P., Udaya Shankar, N., Srivani, K., Subrahmanyan, R., Tingay, Steven, Wayth, Randall, Webster, R., Williams, Andrew, Williams, C., Zheng, Q.

SDSS-IV MaNGA: star formation cessation in low-redshift galaxies I: dependence on stellar mass and structural properties by Wang, Enci, Li, Cheng, Xiao, Ting, Lin, Lin, Bershady, Matthew, Law, David R., Merrifield, Michael, Sanchez, Sebastian F., Riffel, Rogemar A., Riffel, Rogério, Yan, Renbin

“…We have further divided the sample at fixed mass by both bulge-to-total luminosity ratio and morphological type, finding that our conclusions hold regardless of these factors: it appears that the presence of a central dense object is not a driving parameter, but rather a byproduct of the star formation cessation process.…”

AMI radio continuum observations of young stellar objects with known outflows by Ainsworth, R., Scaife, A., Ray, T., Buckle, J., Davies, M., Frantzen, T., Grainge, K., Hobson, M., Hurley-Walker, Natasha, Lasenby, A., Olamaie, M., Perrott, Y., Pooley, G., Richer, J., Rodriguez-Gonzalvez, C., Saunders, R., Schammel, M., Scott, P., Shimwell, T., Titterington, D., Waldram, E.

“…We present 16 GHz (1.9 cm) deep radio continuum observations made with the Arcminute Microkelvin Imager (AMI) of a sample of low-mass young stars driving jets. We combine these new data with archival information from an extensive literature search to examine spectral energy distributions (SEDs) for each source and calculate both the radio and sub-mm spectral indices in two different scenarios: (1) fixing the dust temperature (Td) according to evolutionary class; and (2) allowing Td to vary. …”

OMEGA - OSIRIS mapping of emission-line galaxies in A901/2: III. - Galaxy properties across projected phase space in A901/2 by Weinzirl, Tim, Aragón-Salamanca, Alfonso, Gray, Meghan E., Bamford, Steven P., Rodriguez Del Pino, Bruno, Chies-Santos, Ana L., Böhm, Asmus, Wolf, Christian, Cool, Richard J.

“…However, there remains a reduced fraction of star-forming galaxies in the centres of the clusters at fixed stellar mass, consistent with the star formation–density relation in galaxy clusters. (5) There is no change in specific Hα-derived star formation rates of star-forming galaxies at fixed mass across the cluster environment. …”

Essays on political economy, leader demographics and corporate finance: evidence from China by Chu, Honghu

“…Our finding shows that the general political connections and the board chair’s political connections are significantly negatively related to firm performance at the highest 1% level (three-star). The CEO’s political connection is also significantly negatively related to firm performance with a significance of 5% level (two-star). …”

Array-Aided Precise Orbit and Attitude Determination of CubeSats using GNSS by Allahvirdizadeh, Amir, El-Mowafy, Ahmed

“…In the estimation process, multi- and affine-constrained models are used to precisely determine the attitude, and then, highly precise observations for an antenna array are reconstructed based on fixed ambiguities and a decorrelation step. Validations confirm the significance of integer ambiguities in the model, highlighting the cost-effectiveness of this model compared with star trackers for attitude determination. …”

A Study of Topology Characteristics on the Real Deployment of Wireless Sensor Networks by Jaganathan, M., Krishnan, V. R., Zakaria, Mohd Sharim, Ahmad, Mohd Riduan

“…In the case of centralized WSN with star topology, we discovered an interesting finding that the various transmit powers (ranging from 3.2dBm to -17dBm) do not vary the consumed power or in other word, the consumed powers across various transmit powers are almost the same for a given fixed distance value. …”
