Synthesis of water-soluble chiral DOTA lanthanide complexes with predominately twisted square antiprism isomers and circularly polarized luminescence emission

One-step cyclization of a tetraazamacrocycle 5 with 70% yield in a 25-g scale was performed. Its chiral DOTA derivatives, L4, has ∼93% of TSAP coordination isomer in its Eu(III) and Yb(III) complexes in aqueous solution. [GdL4]5– exhibits a high relaxivity, making it a promising and efficient MRI contrast agent. High luminescence dissymmetry factor (glum) values of 0.285 (ΔJ = 1) for [TbL3]– and 0.241 (ΔJ = 1) for [TbL4]5– in buffer solutions were recorded

Employee Preference on Sustainable Organizational Messaging According to Individual Differences

Sustainable human resource management is an emerging practice in the future of global business environments. Research into this topic has been accelerated as organizations are moving away from the standard business protocols and onto more sustainable methods. This study builds on prior research investigating employees\u27 preferences regarding organizational sustainability communications (e.g. Joyal-Desmarais et al., 2022; Kataria et al., 2013). In this study, we assess the relationship between employee individual differences and sustainability informational meetings attendance preferences. Additionally, this study aims to examine the potential relationship between individuals\u27 egoistic, altruistic, and biospheric values using a scale developed by de Groot and Steg (2008) and preferences for value-laden organizational sustainability messaging. Finally, this study will take an exploratory view regarding relationships between other demographic variables, intent to attend a sustainable orientation sessions, and value preferences. We recruited 201 respondents on Prolific and then distributed a survey through Qualtrics for respondents to complete. Measures will be assessed with factor analysis, and relationships will be assessed with correlation and regression. We expect that individual differences will predict an individual\u27s sustainable message preferences. Additionally, we expect to find positive correlations between an individual\u27s ratings on egoistic, altruistic, and biospheric values and their preferences for matching value-laden sustainable messaging. The findings of this study will inform business leaders on effective practices that may increase the attendance of their orientation sessions regarding sustainable business practices and contribute to the emerging research field of employee sustainability message preferences

‘We don't have recipes; we just have loads of ingredients’: explanations of evidence and clinical decision making by speech and language therapists

Rationale, aims and objectives: Research findings consistently suggest that speech and language therapists (SLTs) are failing to draw effectively on research-based evidence to guide clinical practice. This study aimed to examine what constitutes the reasoning provided by SLTs for treatment choices and whether science plays a part in those decisions. Method: This study, based in Ireland, reports on the qualitative phase of a mixed-methods study, which examined attitudes underpinning treatment choices and the therapy process. SLTs were recruited from community, hospital and disability work settings via SLT managers who acted as gatekeepers. A total of three focus groups were run. Data were transcribed, anonymized and analysed using thematic analysis. Results: In total, 48 participants took part in the focus groups. The majority of participants were female, represented senior grades and had basic professional qualifications. Three key themes were identified: practice imperfect; practice as grounded and growing; and critical practice. Findings show that treatment decisions are scaffolded primarily on practice evidence. The uniqueness of each patient results in dynamic and pragmatic practice, constraining the application of unmodified therapies. Conclusion: The findings emerging from the data reflect the complexities and paradoxes of clinical practice as described by SLTs. Practice is pivoted on both the patient and clinician, through their membership of groups and as individuals. Scientific thinking is a component of decision making; a tool with which to approach the various ingredients and the dynamic nature of clinical practice. However, these scientific elements do not necessarily reflect evidence-based practice as typically constructed

Homeward bound or bound for a home? Assessing the capacity of dementia patients to make decisions about hospital discharge: Comparing practice with legal standards

Background This article stems from a larger project which considers ways of improving assessments of capacity and judgements about best interests in connection with people with dementia admitted to acute hospitals with respect to decisions about place of residence. Aims Our aim is to comment on how assessments of residence capacity are actually performed on general hospital wards compared with legal standards for the assessment of capacity set out in the Mental Capacity Act, 2005 (MCA). Method Our findings are grounded in ethnographic ward-based observations and in-depth interviews conducted in three hospital wards, in two hospitals (acute and rehabilitation), within two NHS healthcare trusts in the North of England over a period of nine months between 2008 and 2009. Twenty-nine patient cases were recruited to the study. We also draw from broader conceptions of capacity found in domestic and international legal, medical, ethical and social science literature. Results Our findings suggest that whilst professionals profess to be familiar with broad legal standards governing the assessment of capacity under the MCA, these standards are not routinely applied in practice in general hospital settings when assessing capacity to decide place of residence on discharge from hospital. We discuss whether the criteria set out in the MCA and the guidance in its Code of Practice are sufficient when assessing residence capacity, given the particular ambiguities and complexities of this capacity. Conclusions We conclude by suggesting that more specific legal standards are required when assessing capacity in this particular context

Signal Cost and Value Alignment in Organizational Sustainability Messaging to New Hires

Introduction As companies continue to integrate sustainable initiatives as a strategic focus, their communications to new hires must adapt accordingly. Orientation programs represent an opportunity to inform new hires about the company’s sustainability values, but factors influencing the impact of sustainability messaging on new-hire perceptions remain unexplored. It is important for organizations to send signals to their new hires which are perceived as credible, meaningful, and genuine. However, the framing of sustainability orientation messages may combine with new-hire individual differences to influence these perceptions. We draw from signaling theory and value congruence research in HR to consider the potential impact of organizational sustainability messaging content and emphasis in the orientation context on organizationally pertinent new hire attitudes and perceptions. Signaling theory, in this case, applies to how costly of a signal the organization sends to their incoming employees. Costly signals shown to new employees within the orientation process demonstrates credibility in the organization\u27s sustainable initiatives. Methodology We conducted an experimental vignette study in which we manipulated signal costliness and intrinsic vs. extrinsic motivation in the administration of a hypothetical new employee orientation presentation, creating a 2x2 factorial design. Surveys were used for manipulation checks and to capture all other variables. The experimental vignettes were developed with an eye toward both construct capture and context richness, based on guidelines and recent uses of vignette methodology in personnel research. Using Mturk, we obtained responses from a heterogeneous sample of working adults (n = 489). These responses were evenly distributed among the 4 conditions. Expected Findings and Analyses We will examine main effects and interaction effects of our independent variables on outcomes such as perceived credibility, perceived organizational sustainability, and intent to engage with organizational sustainability initiatives. In addition, we will perform moderation analyses to assess the potential influence of individual differences on those effects. From this experiment, we expect to find that costly signals will illustrate higher credibility. Additionally, we expect to find intrinsically motivated messaging and extrinsically motivated messaging to resonate more strongly with individuals that are intrinsically motivated and individuals that are extrinsically motivated, respectively

Active citizenship and aquired neurological communication difficulty

People with communication impairments may face barriers to civic participation, with resulting marginalisation of individuals who wish to be actively involved. The investigation aimed to explore the experience of civically engaged adults with acquired neurological communication difficulties. Six people with acquired neurological communication difficulties were interviewed. Discussion included the definition of active citizenship, their civic involvement, motivations, related barriers and facilitators. Qualitative analysis was undertaken, with data categorised, coded and examined for recurring themes. All participants were active in disability-related organisations and four undertook wider civic roles. Motivations included activity being outwith the home and wanting to effect change for themselves and the populations they represented. Disability group meetings were more positive experiences than broader community activities, which were associated with fatigue and frustration, commonly resulting from communication difficulties and unmet support needs. All participants identified a need for professional and public educational about disability and communication and made recommendations on content, methods and priority groups. For these participants civic engagement had positive and negative dimensions. Speech and language therapists should promote reduction of the barriers that impede the active citizenship rights of people with communication support needs. Civic participation may be a relevant measure of outcome in communication impaired populations

Performative Work: Bridging Performativity and Institutional Theory in the Responsible Investment Field

Callon’s performativity thesis has illuminated how economic theories and calculative devices shape markets, but has been challenged for its neglect of the organizational, institutional and political context. Our seven-year qualitative study of a large financial data company found that the company’s initial attempt to change the responsible investment field through a performative approach failed because of the constraints posed by field practices and organizational norms on the design of the calculative device. However, the company was subsequently able to put in place another form of performativity by attending to the normative and regulative associations of the device. We theorize this route to performativity by proposing the concept of performative work, which designates the necessary institutional work to enable translation and the subsequent adoption of the device. We conclude by considering the implications of performative work for the performativity and the institutional work literatures

A large-scale automated radio telemetry network for monitoring movements of terrestrial wildlife in Australia

Technologies for remotely observing animal movements have advanced rapidly in the past decade. In recent years, Australia has invested in an Integrated Marine Ocean Tracking (IMOS) system, a land ecosystem observatory (TERN), and an Australian Acoustic Observatory (A2O), but has not established movement tracking systems for individual terrestrial animals across land and along coastlines. Here, we make the case that the Motus Wildlife Tracking System, an open-source, rapidly expanding cooperative automated radio-tracking global network (Motus, https://motus.org) provides an unprecedented opportunity to build an affordable and proven infrastructure that will boost wildlife biology research and connect Australian researchers domestically and with international wildlife research. We briefly describe the system conceptually and technologically, then present the unique strengths of Motus, how Motus can complement and expand existing and emerging animal tracking systems, and how the Motus framework provides a much-needed central repository and impetus for archiving and sharing animal telemetry data. We propose ways to overcome the unique challenges posed by Australia’s ecological attributes and the size of its scientific community. Open source, inherently cooperative and flexible, Motus provides a unique opportunity to leverage individual research effort into a larger collaborative achievement, thereby expanding the scale and scope of individual projects, while maximising the outcomes of scant research and conservation funding
