The Space They Take: Evaluating Historically White Fraternities through Critical Race Theory
Fraternities and sororities are not often thought of as the starting points for social justice education, especially not historically White fraternities and sororities. In this paper, I outline the missions and values of a select group of historically White fraternities to better understand the foundation from which they are starting their organization. I give an overview of Critical Race Theory (CRT) that gives context for how critical race theory can work in higher education. I conclude with recommendations for reworking historically White fraternities with a CRT lens; recommendations are written for national organizations and students, and then for professional staff working with fraternities and sororities, especially historically White fraternities
Multiplicity of periodic solutions for systems of weakly coupled parametrized second order differential equations
We prove a multiplicity result of periodic solutions for a system of second order differential equations having asymmetric nonlinearities. The proof is based on a recent generalization of the Poincar\ue9\u2013Birkhoff fixed point theorem provided by Fonda and Ure\uf1a
A new methodology to evaluate Human Workload State Inference
Electronics and automation are increasingly part
of our daily lives, and led to the introduction of systems and
intelligent machines to which the human work is delegated and
that collaborate and support the user in the conduct of mancritical
operations.
The University of Modena and Reggio Emilia is partner of
the european project “Designing Dynamic Distributed
Cooperative Human-Machine Systems” (D3CoS,
www.d3cos.eu), that aim is the definition of affordable methods,
techniques and tools which go beyond assistance systems and
consequently address the specification, development and
evaluation of cooperative systems from a multi-agent
perspective where human and machine agents are in charge of
common tasks, assigned to the system as a whole. The key on
which to base the cooperation between the machine and the
human is the amount of workload of the human operator.
So we were involved into investigate aspects of the functional
state of human operators interacting with the demonstrator in
the unmanned aerial vehicle (UAV) and maritime domains. We
analyzed and correlated objective psycho-physiological
measures: eye blinks, respiration rate and amplitude, electro
dermal activity, heart rate variability, blood pressure; with
subjective self-assessed measure evaluated with two
questionnaires: NASA-TLX and Rating Scale Mental Effort
(RSME); with the aim to realize a mathematical regression
model for classifying the mental operators workload.
Keywords— Workload, psycho-physiological measures,
statistical analysis, cooperative systems
An extension of the Poincaré–Birkhoff Theorem coupling twist with lower and upper solutions
In 1983, Conley and Zehnder proved a remarkable theorem on the periodic problem associated with a general Hamiltonian system, giving a partial answer to a conjecture by Arnold. Their pioneering paper has been extended in different directions by several authors. In 2017, Fonda and Ureña established a deeper relation between the results by Conley and Zehnder and the Poincaré–Birkhoff Theorem. In 2020, Fonda and Gidoni pursued along this path in order to treat systems whose Hamiltonian function includes a nonresonant quadratic term. It is the aim of this paper to further extend this fertile theory to Hamiltonian systems which, besides the periodicity-twist conditions always required in the Poincaré–Birkhoff Theorem, also include a term involving a pair of well-ordered lower and upper solutions. Phase-plane analysis techniques are used in order to recover a saddle-type dynamics permitting us to apply the above mentioned results

INTRINSIC MECHANISM FOR ENTROPY CHANGE IN CLASSICAL AND QUANTUM EVOLUTION
It is shown that the existence of a time operator in the Liouville space
representation of both classical and quantum evolution provides a mechanism for
effective entropy change of physical states. In particular, an initially
effectively pure state can evolve under the usual unitary evolution to an
effectively mixed state.Comment: 20 pages. For more information or comments contact E. Eisenberg at

Hubungan Antara Konformitas Dengan Intensi Prososial Pada Remaja Warga Binaan Pemasyarakatan Lapas Anak Kelas II a Kutoarjo
Penelitian ini bertujuan untuk mengkaji hubungan antara konformitas dengan intensi prososial pada remaja warga binaan pemasyarakatan LAPAS Anak Kelas II A Kutoarjo.Populasi penelitian ini yaitu remaja warga binaan pemasyarakatan LAPAS Anak Kelas II A Kutoarjo sebanyak 110 orang. Sampel penelitian sebanyak 78 orang, sampel diambil dengan menggunakan teknik simple random sampling. Pengumpulan data menggunakan dua buah Skala Psikologi yaitu Skala Intensi Prososial (24 aitem valid, α = 0.834) dan Skala Konformitas (22 aitem valid, α = 0.836).Hasil penelitian menunjukkan koefisien korelasi rxy = 0.447 dengan p=0,000 (p<0,05). Hasil tersebut menunjukkan bahwa hipotesis yang diajukan peneliti, yaitu terdapat hubungan positif antara konformitas dengan intensi prososial dapat diterima.Nilai koefisien korelasi positif menunjukkan bahwa arah hubungan kedua variabel adalah positif, artinya semakin tinggi konformitas maka semakin tinggi intensi prososial. Konformitas memberikan sumbangan efektif sebesar 19.9% pada intensi prososial dan sebesar 80.1% dipengaruhi oleh faktor lain yang tidak diteliti dalam penelitian ini
