Shane M Parker, Dmitrij Rappoport, Filipp Furche
We report on the efficient Turbomole implementation of quadratic response properties within the time-dependent density functional theory (TDDFT) context that includes the static and dynamic dipole hyperpolarizability, ground-to-excited-state two-photon absorption amplitudes (through a single residue) and state-to-state one-photon absorption amplitudes (through a double residue). Our implementation makes full use of arbitrary (including non-Abelian) point-group symmetry as well as permutational symmetry and enables the calculation of nonlinear properties with hybrid density functionals for molecules with hundreds of atoms and thousands of basis functions at a cost that is a fixed multiple of the cost of the corresponding linear properties...

Shan Jiang, Jingsheng Zhao
The definition of ashi point has not been unified yet till now. Likewise, the precise explanation on its connotation has always been an elusive question in acupuncture theory. By collecting diverse definitions on ashi point in the textbooks of Acupuncture and Moxibustion, dictionaries and term standards, several rational elements in definitions with consensus were screened. With the assistance of two important theories of cognitive linguistics, such as figure-ground theory and distance iconicity theory, the concept of ashi point was newly defined...

INTRODUCTION: High-quality residency training is of utmost importance for residents to become competent medical specialists. Hospital-wide education committees have been adopted by several healthcare systems to govern postgraduate medical education and to support continuous quality improvement of residency training. To understand the functioning and potential of such committees, this study examined the mechanisms through which hospital-wide education committees strive to enable continuous quality improvement in residency training...

The photophysical properties of two pyrene-bodipy molecular dyads, composed of a phenyl-pyrene (Py-Ph) linked to the meso position of a bodipy (BD) molecule with either H-atoms (BD1) or ethyl groups (BD2) at the 2,6 positions, are investigated by stationary, nanosecond and femtosecond spectroscopy. The properties of these dyads (Py-Ph-BD1 and Py-Ph-BD2) are compared to those of their constituent chromophores in two solvents namely 1,2-dichloroethane (DCE) and acetonitrile (ACN). Stationary spectroscopy reveals a weak coupling among the subunits in both dyads...

This article describes a mixed methods study of community-based participatory research (CBPR) partnership practices and the links between these practices and changes in health status and disparities outcomes. Directed by a CBPR conceptual model and grounded in indigenous-transformative theory, our nation-wide, cross-site study showcases the value of a mixed methods approach for better understanding the complexity of CBPR partnerships across diverse community and research contexts. The article then provides examples of how an iterative, integrated approach to our mixed methods analysis yielded enriched understandings of two key constructs of the model: trust and governance...

BACKGROUND: Hospitals must make a profit to ensure their continued existence. The observed rises in case numbers and case-mix indices lead us to suspect that the admission, treatment, and discharge of patients are now being influenced not just by purely medical factors, but also by economic considerations with a view toward making a profit-i.e., that decision-making has become partially commercialized. In this study, we investigated whether doctors and hospital chief executive officers (CEOs) share this perception of their professional environment...

BACKGROUND: Living with and caring for someone with chronic illness can lead to limitations in activity and social participation for the care partner. Past research emphasizes the importance of care partners taking care of themselves physically and emotionally so they can stay healthy to support the care recipient. There is little information regarding how the care partner takes care of their own social lives. The purpose of this study was to explore the concept of social self-management from the perspective of spousal care partners of people with Parkinson's disease...

Saltanat Childress, Deborah Gioia, Jacquelyn C Campbell
This paper provides an account of the adverse impacts of domestic violence on women in Kyrgyzstan and develops a grounded theory of coping among survivors of abuse. The results indicate that women adopt a range of strategies to prevent, avert, and minimize anticipated violence. Two key aspects of coping appeared in the narratives: 1) maintaining the status quo and 2) developing agency to resist the abuse. The results suggest that Government and nongovernmental organizations must take additional action to draw women to formal violence prevention services...

A combination of time-resolved vibrational spectroscopy and density functional theory techniques have been applied to study the vibrational energy relaxation dynamics of the Re(4,4'-dicyano-2,2'-bipyridine)(CO)3Cl (Re(CO)3Cl) catalyst for CO2 to CO conversion bound to gold surfaces. The kinetics of vibrational relaxation exhibits a biexponential decay including an ultrafast initial relaxation and complete recovery of the ground vibrational state. Ab initio molecular dynamics simulations and time-dependent perturbation theory reveal the former to be due to vibrational population exchange between CO stretching modes and the latter to be a combination of intramolecular vibrational relaxation (IVR) and electron-hole pair (EHP) induced energy transfer into the gold substrate...

BACKGROUND: Livestock can promote resilience in low-income communities through a number of pathways. Livestock development programs seek to amplify these benefits but often fail to consider the costs to intended beneficiaries or the effect of prevailing gender norms. OBJECTIVE: To explore perceptions of livestock ownership among female smallholder livestock keepers in Nyanza Region, Kenya, and unpack how the distribution of livestock benefits and investments varies by gender within households...

Contextual bandits have become popular as they offer a middle ground between very simple approaches based on multi-armed bandits and very complex approaches using the full power of reinforcement learning. They have demonstrated success in web applications and have a rich body of associated theoretical guarantees. Linear models are well understood theoretically and preferred by practitioners because they are not only easily interpretable but also simple to implement and debug. Furthermore, if the linear model is true, we get very strong performance guarantees...

The European Union Water Framework Directive (EU WFD, 2000) calls for active inclusion of the public in the governance of waterbodies to enhance the effectiveness and legitimacy of water management schemes across the EU. As complex socio-ecological systems, river basins in western Europe could benefit from further support for inclusive management schemes. This paper makes use of case studies from Germany, England and Spain to explore the potential opportunities and challenges of different participatory management approaches...

Lack of affordable housing access represents a significant and growing problem for low-income households in the United States and these housing challenges may present barriers to the management of chronic diseases such as type 2 diabetes. In this qualitative study, we examined how both housing challenges and housing resources shaped diabetes self-management behaviors. We conducted semi-structured interviews with 40 low-income residents of one US city, New Haven, Connecticut, who had a diagnosis of type 2 diabetes and either resided in or qualified for subsidized housing...

OBJECTIVE: Personality psychology has largely ignored the experiences of people with disabilities. This paper strives to bring the thriving, interdisciplinary field of disability studies to personality psychology via a case study of Samantha (N=1). Samantha feels that she grew up as a hearing person who could not hear and is now a deaf person who can hear. METHOD: Narrative identity provides the theoretical, methodological, and analytical framework for the rich, qualitative examination of Samantha's life story, interwoven with approaches from disability studies and intersectionality theory...

BACKGROUND: Despite expansion of interest among American medical students in global health (GH), academic medical centers face multiple obstacles to the development of structured GH curricula and career guidance. To meet these demands we sought to provide a systematic analysis of the accounts of GH experts. METHODS: We developed a collaborative, interview-based, qualitative analysis of GH experiences across six career-related themes that are relevant to medical students interested in GH: justification, medical education, economics, research prospects, law and ethics, and work-life balance...

BACKGROUND: Globalization has increased the demand for international experiences in medical education. International experiences improve medical knowledge, clinical skills, and self-development; influence career objectives; and provide insights on ethical and societal issues. However, global health rotations can end up being no more than tourism if not structured to foster personal transformation and global citizenship. OBJECTIVE: We conducted a qualitative assessment of trainee-reported critical incidents to more deeply understand the impact of our global health experience on trainees...

The adiabatic theorem is a fundamental result in quantum mechanics, which states that a system can be kept arbitrarily close to the instantaneous ground state of its Hamiltonian if the latter varies in time slowly enough. The theorem has an impressive record of applications ranging from foundations of quantum field theory to computational molecular dynamics. In light of this success it is remarkable that a practicable quantitative understanding of what "slowly enough" means is limited to a modest set of systems mostly having a small Hilbert space...

INTRODUCTION: Adolescent girls in sub-Saharan Africa are disproportionately affected by HIV due to a range of social and structural factors. As they transition to adulthood, they are recipients of increasing blame for HIV infection and 'improper' sex, as well as increasing scrutiny, restrictions and surveillance. This study used a qualitative and participatory approach to explore the messaging and restrictions imposed on adolescent girls living with HIV in Zambia. METHODS: Thirty-four in-depth interviews and four participatory workshops were carried out with 24 adolescent girls aged 15 to 19 years old living with HIV in Lusaka, Zambia...

Using a Constructivist Grounded Theory approach (Charmaz, 2006), this research examined the social construct of the “professional boundary” necessary in mental health therapeutic work and the problem of professional boundary violations in the therapeutic relationship. Thirteen mental health clinicians from various professional disciplines commonly found in mental health clinical practice responded to three specific questions designed to gain an understanding about how clinicians gauge the differences between minor and serious boundary violations...
