Understanding Guatemala’s Cultural Heritage: Extending Protection to Colonial Art in the Memorandum of Understanding Between the United States and Guatemala
In this paper, we report on our experimental observations of the resonant ionization of a phosphorus donor in silicon in a homogeneous electric field, which is expressed in the sudden rise of the conductivity of the sample at a low temperature when the electric field approaches the critical value of ∼3.2 MV m-1. The effect is discussed in terms of the field-induced interaction of the states using a simplified model based on the effective-mass theory. The results from our model are qualitatively similar to the previously published advanced model base, which is based on the first principles; this predicts the ionization thresholds at approximate fields of 2.45 and 3.25 MV m-1, the latter being in very good agreement with our experiment. The possibility of observing more than one resonance is also discussed
Family Caregivers: From Invisible to Visible Within the Healthcare Continuum
As the United States\u27 aging population rapidly grows, the prevalence of adults with chronic illness or disabilities who require intermittent or long-term caregiving from family members also increases. Despite the prevalence of caregiving, the role of the family caregiver is a label that lacks a clear description, definition, or societal understanding. The inability to identify family caregivers creates negative ramifications, including diminished recognition and support throughout the healthcare continuum. Drawing from caregiver identity theory, this qualitative phenomenological study aimed to describe the experiences of family caregivers to promote a deeper understanding of how they became aware of their caregiver identity and role in the healthcare system. The data included semi-structured interviews with a diverse group of 12 family caregivers currently caring for parents, grandparents, siblings and significant others over the age of 65. As suggested in the caregiver identity theory, the findings in this study confirmed that identity as a family caregiver is a complex change process. Additionally, this study found that awareness and acceptance of one\u27s family caregiver role/identity are not synonymous, but are shaped/influenced by previous experiences within their family or work life, cultural norms, prior relationships with their loved one, and the external labeling process. These findings indicate that identifying as a caregiver is not always a simple or automatic process of acknowledging that what they are doing is family caregiving, with some participants actively rejecting or feeling ambivalent about the caregiver label. Implications of this research supports the need for education for healthcare professionals, patients and family caregivers to ensure caregivers are routinely identified throughout the healthcare continuum, and their needs are assessed and supported as a standard of practice in delivering family-centered healthcar
