Z is for Zany: Infants and Toddlers Edition
Oh the magic of babies' first bursts of laughter and the wriggling exuberance of toddler delight! Given the hard work of caring for little ones, it's a good thing that they share their pleasure so outwardly and freely. It is one of the gifts of being in the presence of these very young human beings. Witnessing your little one's glee goes deeper than the enjoyment of the moment. One of the side effects of shared laughter is a deep sense of fellowship and safety with those who laugh with you
Measurement-Device-Independent Approach to Entanglement Measures
Within the context of semiquantum nonlocal games, the trust can be removed
from the measurement devices in an entanglement-detection procedure. Here we
show that a similar approach can be taken to quantify the amount of
entanglement. To be specific, first, we show that in this context a small
subset of semiquantum nonlocal games is necessary and sufficient for
entanglement detection in the LOCC paradigm. Second, we prove that the maximum
pay-off for these games is a universal measure of entanglement which is convex
and continuous. Third, we show that for the quantification of
negative-partial-transpose entanglement, this subset can be further reduced
down to a single arbitrary element. Importantly, our measure is operationally
accessible in a measurement-device-independent way by construction. Finally,
our approach is simply extended to quantify the entanglement within any
partitioning of multipartite quantum states.Comment: 8 pages, 2 figures, the main result is split into two theorems with

Micro-Sociological Implications of Domestic Violence on Adolescents in a School Setting
Adolescent victimization and exposure to domestic violence has the ability to yield negative psychological, social, behavioral, developmental, and cognitive outcomes. Unfortunately, violence within the home is becoming increasingly prevalent. In 2007 alone, the U.S. Department of Health and Human Services reported that roughly 794,000 adolescents were either abused or neglected within their household (Sousa et al. 2011:112). Another form of violence that is becoming recognized as a widespread public-health concern is intimate partner violence. According to the U.S. Department of Justice, intimate partner violence is present when the juvenile is not directly involved and acts more as a witness to domestic violence between his/her caregivers. Within many households where this occurs, adolescents may witness the physical and emotional pain inflicted on adult victims, or they may not actually observe the altercations but are well aware of their existence. It is conservatively estimated that over 200,000 cases of intimate partner violence occur in the United States annually (Sousa et al. 2011:112). Within this Literature Review, the overall purpose is to examine how the side effects of domestic violence impact an adolescent’s school performance. This paper will analyze several characteristics that come with the results of domestic violence separately, such as developmental, psychological, cognitive, social, and behavioral outcomes in order to sufficiently explain how this public-health problem impacts adolescents within a school setting. This paper will mainly focus on the negative outcomes associated with this phenomenon in heterosexual relationships, as they are the most commonly reported
Discovering Resilience in Children who Witnessed their Caregivers with Cancer: A Retrospective Study
Cancer is a powerful disease and has been shown to affect both the individual battling the disease as well as the friends and families. Research has shown that children and/or adolescents who have witnessed their caregivers with cancer have emerged as resilient from this experience. Through interviews, this study investigated college students at a small liberal arts school in Southern New England, who have or have had primary caregivers with cancer to see if they have gained resilience. This study revealed the effects that cancer can have not only on the individual who is battling the disease, but also on the children and/or adolescents who have witnessed their struggle. It identified possible support systems that were used by the college students to cope with their caregiver’s cancer. Information from this study can be used to understand if children and/or adolescents that grow up with a parent with cancer may develop resiliency as they mature and grow older
Witnessing single-photon entanglement with local homodyne measurements: analytical bounds and robustness to losses
Single-photon entanglement is one of the primary resources for quantum
networks, including quantum repeater architectures. Such entanglement can be
revealed with only local homodyne measurements through the entanglement witness
presented in [Morin et al. Phys. Rev. Lett. 110, 130401 (2013)]. Here, we
provide an extended analysis of this witness by introducing analytical bounds
and by reporting measurements confirming its great robustness with regard to
losses. This study highlights the potential of optical hybrid methods, where
discrete entanglement is characterized through continuous-variable
measurements
