The Congruence of Academic Motivation and Catholic Education
Student motivation is of central concern for all teachers, as students cannot learn if they are not engaged and attentive during class. This essay describes how Catholic schools are uniquely designed to promote positive motivational patterns in students based on their foundation in the mysteries of the Catholic faith. The Paschal Mystery relates to students pursuing mastery goals and persisting through challenges, the Trinitarian Mystery reflects the focus on community and belongingness, the Incarnation relates to striving for excellence, and the Eucharist reflects the need for purpose. When Catholic schools are rooted in these mysteries and the mission of the Church, students are primed for a positive motivational experience in school
School Improvement in the Digital Age: A Study of the Alliance for Catholic Education Blended Learning Pilot
This article presents a description of the Alliance for Catholic Education’s (ACE’s) approach to and experience of implementing a pilot blended learning and school improvement initiative in five Catholic schools in three U.S. (arch)dioceses. Program evaluation data is summarized, including results of teacher surveys measuring increases in perceptions of knowledge of and attitudes toward components of the model. The project description and findings offer a model for other Catholic schools considering introducing blended learning approaches as part of school improvement efforts
No Good Options: Analysis of Catholic School Reopening Plans in Fall 2020
As schools across the country made decisions about how to safely reopen during the COVID-19 pandemic in the Fall of 2020, Catholic schools reopened for in-person instruction more than surrounding public schools. This study analyzes published reopening plans from 136 Catholic schools in 18 different states to explore how schools reopened and how they communicated their plans. Results showed that Catholic schools mostly did not decide to reopen virtually, consistent with local health data trends and public school decisions. Rather, Catholic schools offered in-person education with health and safety protocols in place. Most schools in the sample did not communicate their plans in full on their websites. Plans that were accessible on websites were analyzed based on the National Standards and Benchmarks of Effective Catholic Schools for evidence of the added value of Catholic education during this time
Measuring Students’ Sense of School Catholic Identity
As a ministry of the Catholic Church, Catholic schools are charged with educating students’ hearts and minds. Multiple standardized academic tests and other student assessments are available for monitoring both student and teacher outcomes in Catholic schools, but fewer measures exist for considering the school’s faith-related mission. Although tests of student religious knowledge and benchmarks related to specific Catholic elements of the school are available, we do not yet have a robust set of instruments that provide teachers and leaders an understanding of their progress in providing a school environment permeated by Catholic culture and faith. To consider how students in Catholic schools perceive the Catholicity of their school and how these perceptions vary among different student groups, we developed, piloted, and validated the Sense of School Catholic Identity Survey (SSCI). This 20-item survey measures Grade 5 through 8 students’ perceptions of their Catholic school as personal and invitational, sacramental, unitive, and eucharistic. Findings from the pilot study suggest that responses differ by student grade level, religious tradition, and gender. Future testing of the scale will examine school-level differences in Catholic identity
How accurate are drug cryptomarket listings by content, weight, purity and repeat purchase?
Purpose: Drug cryptomarkets increase information available to market actors, which should reduce information asymmetry and increase market efficiency. This study aims to determine whether cryptomarket listings accurately represent the advertised substance, weight or number and purity, and whether there are differences in products purchased from the same listing multiple times.
Design/methodology/approach: Law enforcement drug purchases – predominantly cocaine, methamphetamine, MDMA and heroin – from Australian cryptomarket vendors (n = 38 in 2016/2017) were chemically analysed and matched with cryptomarket listings (n = 23). Descriptive and comparative analyses were conducted.
Findings: Almost all samples contained the advertised substance. In most of these cases, drugs were either supplied as-advertised-weight or number, or overweight or number. All listings that quantified purity overestimated the actual purity. There was no consistent relationship between advertised purity terms and actual purity. Across the six listings purchased from multiple times, repeat purchases from the same listing varied in purity, sometimes drastically, with wide variation detected on listings purchased from only one month apart.
Research limitations/implications: In this data set, cryptomarket listings were mostly accurate, but the system was far from perfect, with purity overestimated. A newer, larger, globally representative sample should be obtained to test the applicability of these findings to currently operating cryptomarkets.
Originality/value: This paper reports on the largest data set of forensic analysis of drug samples obtained from cryptomarkets, where data about advertised drug strength/dose were obtained
Inclusive jet cross sections and dijet correlations in photoproduction at HERA
Inclusive jet cross sections in photoproduction for events containing a
meson have been measured with the ZEUS detector at HERA using an integrated
luminosity of . The events were required to have a
virtuality of the incoming photon, , of less than 1 GeV, and a
photon-proton centre-of-mass energy in the range . The measurements are compared with next-to-leading-order (NLO) QCD
calculations. Good agreement is found with the NLO calculations over most of
the measured kinematic region. Requiring a second jet in the event allowed a
more detailed comparison with QCD calculations. The measured dijet cross
sections are also compared to Monte Carlo (MC) models which incorporate
leading-order matrix elements followed by parton showers and hadronisation. The
NLO QCD predictions are in general agreement with the data although differences
have been isolated to regions where contributions from higher orders are
expected to be significant. The MC models give a better description than the
NLO predictions of the shape of the measured cross sections.Comment: 43 pages, 12 figures, charm jets ZEU
Dissociation of virtual photons in events with a leading proton at HERA
The ZEUS detector has been used to study dissociation of virtual photons in
events with a leading proton, gamma^* p -> X p, in e^+p collisions at HERA. The
data cover photon virtualities in two ranges, 0.03<Q^2<0.60 GeV^2 and 2<Q^2<100
GeV^2, with M_X>1.5 GeV, where M_X is the mass of the hadronic final state, X.
Events were required to have a leading proton, detected in the ZEUS leading
proton spectrometer, carrying at least 90% of the incoming proton energy. The
cross section is presented as a function of t, the squared four-momentum
transfer at the proton vertex, Phi, the azimuthal angle between the positron
scattering plane and the proton scattering plane, and Q^2. The data are
presented in terms of the diffractive structure function, F_2^D(3). A
next-to-leading-order QCD fit to the higher-Q^2 data set and to previously
published diffractive charm production data is presented
Search for lepton-flavor violation at HERA
A search for lepton-flavor-violating interactions and has been performed with the ZEUS detector using the entire HERA I
data sample, corresponding to an integrated luminosity of 130 pb^{-1}. The data
were taken at center-of-mass energies, , of 300 and 318 GeV. No
evidence of lepton-flavor violation was found, and constraints were derived on
leptoquarks (LQs) that could mediate such interactions. For LQ masses below
, limits were set on , where
is the coupling of the LQ to an electron and a
first-generation quark , and is the branching ratio of
the LQ to the final-state lepton ( or ) and a quark . For
LQ masses much larger than , limits were set on the four-fermion
interaction term for LQs that couple to an electron and a quark
and to a lepton and a quark , where and are
quark generation indices. Some of the limits are also applicable to
lepton-flavor-violating processes mediated by squarks in -Parity-violating
supersymmetric models. In some cases, especially when a higher-generation quark
is involved and for the process , the ZEUS limits are the most
stringent to date.Comment: 37 pages, 10 figures, Accepted by EPJC. References and 1 figure (Fig.

Multijet production in neutral current deep inelastic scattering at HERA and determination of alpha_s
Multijet production rates in neutral current deep inelastic scattering have
been measured in the range of exchanged boson virtualities 10 < Q2 < 5000 GeV2.
The data were taken at the ep collider HERA with centre-of-mass energy sqrt(s)
= 318 GeV using the ZEUS detector and correspond to an integrated luminosity of
82.2 pb-1. Jets were identified in the Breit frame using the k_T cluster
algorithm in the longitudinally invariant inclusive mode. Measurements of
differential dijet and trijet cross sections are presented as functions of jet
transverse energy E_{T,B}{jet}, pseudorapidity eta_{LAB}{jet} and Q2 with
E_{T,B}{jet} > 5 GeV and -1 < eta_{LAB}{jet} < 2.5. Next-to-leading-order QCD
calculations describe the data well. The value of the strong coupling constant
alpha_s(M_Z), determined from the ratio of the trijet to dijet cross sections,
is alpha_s(M_Z) = 0.1179 pm 0.0013(stat.) {+0.0028}_{-0.0046}(exp.)
