Cross effects and calculus in an unbased setting

We study functors F from C_f to D where C and D are simplicial model categories and C_f is the full subcategory of C consisting of objects that factor a fixed morphism f from A to B. We define the analogs of Eilenberg and Mac Lane's cross effects functors in this context, and identify explicit adjoint pairs of functors whose associated cotriples are the diagonals of the cross effects. With this, we generalize the cotriple Taylor tower construction of [10] from the setting of functors from pointed categories to abelian categories to that of functors from C_f to D to produce a tower of functors whose n-th term is a degree n functor. We compare this tower to Goodwillie's tower of n-excisive approximations to F found in [8]. When D is a good category of spectra, and F is a functor that commutes with realizations, the towers agree. More generally, for functors that do not commute with realizations, we show that the terms of the towers agree when evaluated at the initial object of C_f.Comment: 55 pages. With appendix by Rosona Eldred. Submitted to Transactions of the AMS. New version adds section 7 on convergence of the cotriple tower. Second update makes repairs to section 3 in the proof of establishing the cotriple, adds a careful accounting of homotopy (co)limit properties being used in the paper, some of these are established in a new appendi

Using Supervision Preferences of Counselors to Predict Intention to Stay

The demand for counselors continues to grow and agencies continue to look for strategies that will retain their counselors. While improving employee retention requires multiple regular and ongoing actions at all levels of an organization, supporting supervisors to provide quality interactions with counselors could be part of the solution. The purpose of this study was to investigate the relationship between supervision preferences and turnover intention among counselors employed in state agencies. Researchers solicited information regarding the supervision activities that counselors preferred to receive compared to the supervision activities they actually received. Instead of asking what counselors need regarding supervision, this study asked what counselors want. In general, results indicated that the smaller the difference between actual and desired supervision the more counselors stated a desire to stay employed in their current organization. Findings suggest that attending to the supervision preferences of counselors could be part of the solution to helping counselors feel motivated to stay employed in their agency

Perpetrators’ and Victims’ Folk Explanations of Aggressive Behaviors and Desires for Apologies

After an aggressive interaction, perpetrators most want to offer apologies when they have unintentionally harmed another person and victims most want to receive an apology when another person intentionally harmed them. Perpetrators and victims also explain aggressive behaviors differently—perpetrators often explain their own aggressive behaviors by referring to beliefs they considered that led to their behaviors (i.e., “belief” explanations), whereas victims explain perpetrators’ behaviors by referring to background factors that do not mention the perpetrators’ mental deliberations (i.e., “causal history explanations”). Putting these ideas together, the current Registered Report had participants recall either a time they intentionally harmed another person or a time when they were intentionally harmed by another person. Participants then rated several characteristics of the recalled behavior, explained why the behavior occurred, and reported their desire for an apology. As predicted, we found that perpetrators who gave “belief” explanations wanted to give an apology much less than participants who gave “causal history explanations.” However, and inconsistent with our predictions, victims’ desire to receive an apology was similar regardless of how they explained the perpetrators’ behaviors. These findings underscore how perpetrators’ explanations can emphasize (or de-emphasize) the deliberateness of their harmful behaviors and how these explanations are related to their desire to make amends

Scientific Utopia III: crowdsourcing science

Most scientific research is conducted by small teams of investigators who together formulate hypotheses, collect data, conduct analyses, and report novel findings. These teams operate independently as vertically integrated silos. Here we argue that scientific research that is horizontally distributed can provide substantial complementary value, aiming to maximize available resources, promote inclusiveness and transparency, and increase rigor and reliability. This alternative approach enables researchers to tackle ambitious projects that would not be possible under the standard model. Crowdsourced scientific initiatives vary in the degree of communication between project members from largely independent work curated by a coordination team to crowd collaboration on shared activities. The potential benefits and challenges of large-scale collaboration span the entire research process: ideation, study design, data collection, data analysis, reporting, and peer review. Complementing traditional small science with crowdsourced approaches can accelerate the progress of science and improve the quality of scientific research

Star formation in 30 Doradus

Using observations obtained with the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope (HST), we have studied the properties of the stellar populations in the central regions of 30 Dor, in the Large Magellanic Cloud. The observations clearly reveal the presence of considerable differential extinction across the field. We characterise and quantify this effect using young massive main sequence stars to derive a statistical reddening correction for most objects in the field. We then search for pre-main sequence (PMS) stars by looking for objects with a strong (> 4 sigma) Halpha excess emission and find about 1150 of them over the entire field. Comparison of their location in the Hertzsprung-Russell diagram with theoretical PMS evolutionary tracks for the appropriate metallicity reveals that about one third of these objects are younger than ~4Myr, compatible with the age of the massive stars in the central ionising cluster R136, whereas the rest have ages up to ~30Myr, with a median age of ~12Myr. This indicates that star formation has proceeded over an extended period of time, although we cannot discriminate between an extended episode and a series of short and frequent bursts that are not resolved in time. While the younger PMS population preferentially occupies the central regions of the cluster, older PMS objects are more uniformly distributed across the field and are remarkably few at the very centre of the cluster. We attribute this latter effect to photoevaporation of the older circumstellar discs caused by the massive ionising members of R136.Comment: 15 pages, 12 figures.
