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 slight modifications, extended proof

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
