Personal and impersonal passives in Seri
From the introduction: In this paper I will examine and discuss passive constructions in Seri. My purpose will be basically two-fold: first, to present descriptive and typological facts concerning these constructions. My second purpose is to discuss how these facts should be accounted for in an explicit grammar. The paper is divided into three major sections in which alternative treatments of these clauses are discussed. In order to compare these alternatives, I will make them explicit in terms of relational grammar (Perlmutter (1978a, 1978b, in press, to appear), Perlmutter and Postal (1977, in press a, in press b, to appear)). [...] I will argue in favor of the universal characterization of passives and impersonal passives proposed by Perlmutter and Postal (1977, to appear) and Perlmutter (1978a, 1978b)
Cosmology from Type Ia Supernovae
This presentation reports on first evidence for a
low-mass-density/positive-cosmological-constant universe that will expand
forever, based on observations of a set of 40 high-redshift supernovae. The
experimental strategy, data sets, and analysis techniques are described. More
extensive analyses of these results with some additional methods and data are
presented in the more recent LBNL report #41801 (Perlmutter et al., 1998;
accepted for publication in Ap.J.), astro-ph/9812133 .

Cardozo Launches the Perlmutter Center for Legal Justice
The Perlmutter Center for Legal Justice at Cardozo Law will be comprised of two components:
The Perlmutter Forensic Science Educational Program, an ambitious legal education program in scientific evidence for practicing attorneys.
The Perlmutter Freedom Clinic, seeking justice for the unjustly incarcerated, will fight wrongful convictions based on the misuse of scientific evidence and work to obtain clemency for individuals that have been unjustly incarcerated.
The Center will be led by prominent civil rights attorney and criminal justice reform advocate Josh Dubin, who will serve as Executive Director. The Deputy Director will be Derrick Hamilton, a formerly incarcerated individual who studied law in prison and won his own exoneration after serving a 21-year sentence. Mr. Hamilton went on to lead the effort to exonerate five wrongfully incarcerated inmates.https://larc.cardozo.yu.edu/event-invitations-2022/1016/thumbnail.jp
Dean Melanie Leslie’s Office Hours
Join Dean Leslie and Josh Dubin, Executive Director of the Perlmutter Center for Legal Justice, and Derrick Hamilton, Deputy Director of the Perlmutter Center for Legal Justice, to to hear about the Freedom Clinic and their recent clemency work, as well as to ask questions about anything on your mind.https://larc.cardozo.yu.edu/event-invitations-2023/1000/thumbnail.jp
Cosmology under Milne's shadow
Based on the magnitude--redshift diagram for the sample of supernovae Ia
analysed by Perlmutter et al. (1999), Davis & Lineweaver rule out the special
relativistic interpretation of cosmological redshifts at a confidence level of
23 sigma. Here, we critically reassess this result. Special relativity is known
to describe the dynamics of an empty universe, by means of the Milne kinematic
model. Applying only special-relativistic concepts, we derive the angular
diameter distance and the luminosity distance in the Milne model. In
particular, in this model we do not use the underlying metric in its
Robertson-Walker form, so our exposition is useful for readers without any
knowledge of general relativity. We do however, explicitly use the
special-relativistic Doppler formula for redshift. We apply the derived
luminosity distance to the magnitude--redshift diagram for supernovae Ia of
Perlmutter et al. (1999) and show that special relativity fits the data much
better than that claimed by Davis & Lineweaver. Specifically, using these data
alone, the Milne model is ruled out only at a 2 sigma level. Although not a
viable cosmological model, in the context of current research on supernovae Ia
it remains a useful reference model when comparing predictions of various
cosmological models.Comment: 5 pages, 1 figure; a didactic article; matches the version accepted

On the Reality of the Accelerating Universe
Two groups recently deduced the positive value for the cosmological constant,
concluding at a high (>= 99%) confidence level that the Universe should be
accelerating. This conclusion followed from the statistical analysis of dozens
of high-redshift supernovae. In this paper this conclusion is discussed. From
the conservative frequentist's point of view the validity of null hypothesis of
the zero cosmological constant is tested by the classical statistical chi^2
test for the 60 supernovae listed in Perlmutter et al. 1999 (ApJ, 517, 565).
This sample contains 42 objects discovered in the frame of Supernova Cosmology
Project and 18 low-redshift object detected earlier. Excluding the event
SN1997O, which is doubtlessly an outlier, one obtains the result: The
probability for seeing a worse chi^2 - if the null hypothesis is true - is in
the 5% to 8% range, a value that does not indicate significant evidence againts
the null. If one excludes further five possible outliers, proposed to be done
by Perlmutter et al. 1999, then the sample of 54 supernovae is in an excellent
accordance with the null hypothesis. It also seems that upernovae from the
High-z Supernova Search Team does not change the acceptance of null hypothesis.
This means that the rejection of the Einstein equations with zero cosmological
constant - based on the supernova data alone - is still premature.Comment: 11 pages, no figures, accepted for publication in Ap
Bruce Bryant, Released After 30 Years in Prison With the Help of the Perlmutter Center for Legal Justice at Cardozo Law, Visits and Thanks Cardozo Students
In an emotional visit to the Cardozo Law campus on April 26, two days after his release from prison, Bruce Bryant thanked students from The Perlmutter Forensic Science Freedom Field Clinic who helped him win clemency.
A round of applause echoed through the hallway as he arrived with Josh Dubin, the executive director of The Perlmutter Center for Legal Justice at Cardozo Law.https://larc.cardozo.yu.edu/cardozo-news-2023/1014/thumbnail.jp
