Exploring the Lived Experiences of Rural Texas School Counselors Working with Studentsâ Mental Health After the COVID-19 Pandemic
The purpose of this qualitative descriptive phenomenological study was to describe the lived experiences of rural Texas counselors when working with studentsâ mental health in the aftermath of the COVID-19 pandemic. The study aims to answer questions of what school counselors describe as the mental health environment for students in rural Texas schools prior, during, and after the COVID-19 pandemic and the changes in the mental health environment of rural students. Most existing research has been focused on how COVID-19 changed school counselorsâ roles and responsibilities and how the pandemic affected studentsâ mental health. The current study concentrated on the experiences the rural school counselors have had in the time following the pandemic to better understand the current mental health environment for rural students. The theory guiding this study is Kurt Lewinâs theory of change, which helps to describe the pandemicâs effects of change on rural Texas schoolsâ mental health environment in the post-pandemic era by exploring the counselorsâ lived experiences during that time. Data was collected through semistructured interviews with rural school counselors from different regions of Texas. A conceptual mapping task is the methodology used within the study to examine data and information from the interviews. This method permits a flexible yet distinct data-checking process, allowing the participants a voice that is accurately represented for thorough reporting
Brain Activation during Sight Gags and Language-Dependent Humor
Humor is a hallmark of human discourse. People use it to relieve stress and to facilitate social bonding, as well as for pure enjoyment in the absence of any apparent adaptive value. Although recent studies have revealed that humor acts as an intrinsic reward, which explains why people actively seek to experience and create humor, few have addressed the cognitive aspects of humor. We used event-related functional magnetic resonance imaging to differentiate brain activity induced by the hedonic similarities and cognitive differences inherent in 2 kinds of humor: visual humor (sight gags) and language-based humor. Our findings indicate that the brain networks recruited during a humorous experience differ according to the type of humor being processed, with high-level visual areas activated during visual humor and classic language areas activated during language-dependent humor. Our results additionally highlight a common network activated by both types of humor that includes the amygdalar and midbrain regions, which presumably reflect the euphoric component of humor. Furthermore, we found that humor activates anterior cingulate cortex and frontoinsular cortex, 2 regions in the brain that are known to have phylogenetically recent neuronal circuitry. These results suggest that humor may have coevolved with another cognitive specialization of the great apes and humans: the ability to navigate through a shifting and complex social space

Classical and Quantum Interaction of the Dipole
A unified and fully relativistic treatment of the interaction of the electric
and magnetic dipole moments of a particle with the electromagnetic field is
given. New forces on the particle due to the combined effect of electric and
magnetic dipoles are obtained. Four new experiments are proposed, three of
which would observe topological phase shifts.Comment: 10 pages, Latex/Revtex. Some minor errors have been correcte
Heralded quantum steering over a high-loss channel
Entanglement is the key resource for many long-range quantum information
tasks, including secure communication and fundamental tests of quantum physics.
These tasks require robust verification of shared entanglement, but performing
it over long distances is presently technologically intractable because the
loss through an optical fiber or free-space channel opens up a detection
loophole. We design and experimentally demonstrate a scheme that verifies
entanglement in the presence of at least dB of added loss,
equivalent to approximately km of telecommunication fiber. Our protocol
relies on entanglement swapping to herald the presence of a photon after the
lossy channel, enabling event-ready implementation of quantum steering. This
result overcomes the key barrier in device-independent communication under
realistic high-loss scenarios and in the realization of a quantum repeater.Comment: 8 pages, 5 figure
Correspondences and Quantum Description of Aharonov-Bohm and Aharonov-Casher Effects
We establish systematic consolidation of the Aharonov-Bohm and
Aharonov-Casher effects including their scalar counterparts. Their formal
correspondences in acquiring topological phases are revealed on the basis of
the gauge symmetry in non-simply connected spaces and the adiabatic condition
for the state of magnetic dipoles. In addition, investigation of basic two-body
interactions between an electric charge and a magnetic dipole clarifies their
appropriate relative motions and discloses physical interrelations between the
effects. Based on the two-body interaction, we also construct an exact
microscopic description of the Aharonov-Bohm effect, where all the elements are
treated on equal footing, i.e., magnetic dipoles are described
quantum-mechanically and electromagnetic fields are quantized. This microscopic
analysis not only confirms the conventional (semiclassical) results and the
topological nature but also allows one to explore the fluctuation effects due
to the precession of the magnetic dipoles with the adiabatic condition relaxed
âIt doesnât mean Iâm uselessâ How do young people experiencing psychosis contribute to their families and why are their contributions sometimes overlooked?
Purpose: Psychosis is often seen as a âburdenâ on families. and affected individuals frequently hold a negative view of themselves. This study explored the ways in which young adults who have experienced first episode psychosis (FEP) make a positive contribution within their families.
Methods: Fifteen participants (seven young people with experience of psychosis and eight relatives) were interviewed separately. Their accounts were analysed using grounded theory methodology (Charmaz, 2006).
Results: For many individuals, their experience had led to a catastrophic redefinition of their identity. However, they continued to contribute significantly both within their families and within their wider communities. The redefinition of identity sometimes appeared to create a âperceptual filterâ whereby both the person themselves and family members overlooked or minimised their contribution, focusing instead on being alert to signs of psychosis or illness.
Conclusions: Shame and a focus on symptoms rather than achievements and contributions can significantly limit opportunities, expectations, and movement beyond an illness identity. It is important for clinicians to be aware of this and to help young people and their families to notice and value positive contribution, and so promote recovery, well-being and post-traumatic growth
