[Experimental teaching reform of polymer molar mass determination using gel permeation chromatography coupled with light scattering].

Gel permeation chromatography coupled with light scattering (GPC-LS) is among the most common methods for determining the molar masses of polymers. GPC-LS is widely used in polymer science research and has been adopted for many industrial applications owing to its high sensitivity, accuracy, and precision. The determination of polymer molar masses using GPC-LS is an important experimental component of the "Polymer Physics Experiments" course. However, the present GPC-LS experimental teaching content tends to be overly simplistic and lacking in depth. Herein, the original experimental content is expanded and multiple sets of experiments are redesigned: (1) Using commercial polystyrene as an experimental sample, the molar mass, molar mass distribution, radius of gyration, and other molecular structure parameters are determined using GPC-LS; (2) Using two polyacrylonitriles with similar molecular structure parameters, subtle differences in the molar mass distributions of the samples are explored using differential mass distribution curves; (3) By comparing the chromatograms of a series of polyethylene glycols with different molar masses, the effect of molar mass on chromatographic peaks is investigated; and (4) For three different polymers (polyacrylonitrile, poly(methyl methacrylate), and poly(ß-cyclodextrin)), the polymer chain conformations are analyzed using conformation plots (i.e., radius of gyration vs. molar mass). In addition, the experimental teaching method is modified to convert passive learning into active learning, thereby improving the students' self-directed learning ability. This experimental teaching reform will help students obtain a more comprehensive understanding of GPC-LS principles and applications, stimulate their enthusiasm for learning, and improve the teaching quality of the experimental course.

Her contribution to medicine, particularly in women's healthcare, and her engagement in social reform through the Brahmo Samaj and the Indian National Congress, caused significant progress toward gender equality and social justice. This article looks back on her academic accomplishments, medical career, social activism, and lasting legacy, emphasizing her profound influence on medicine and society in India.

Community hospitals of the future: the role of community hospitals to mitigate health system burden in Singapore.

In Singapore, an ageing population with increasing chronic disease burden and complex social circumstances have strained the healthcare system. For the health system to run more efficiently, patients should be appropriately sited according to their medical needs. In Singapore, community hospitals serve as an intermediate inpatient facility managing patients with sub-acute and rehabilitation care needs. Our policy brief uncovers the gaps in transforming community hospital care models and offers actionable steps to unlock the community hospital chokepoints in Singapore's health system. The future community hospitals can accommodate higher acuity but medically stable patients, while patients who do not require inpatient rehabilitation care can be appropriately sited to community partners, if policy, resourcing and technology factors are addressed. An evidence-based, stepwise approach involving all stakeholders will be required to pilot and evaluate new models before large-scale change.

A theory of change evaluation of doctoral admission methods: A case study of a Chinese university.

In response to China's incentive for "connotative development" in doctoral education, universities are actively fostering creative and innovative PhD candidates with enhanced research productivity and superior educational quality. A Chinese university, aligning with this objective, has initiated significant reforms in its doctoral admission methods, introducing a new type of student and altering the proportion of existing ones. Recognizing the complexity and uncertainty inherent in the doctoral admission process, this theory-based study employs a Theory of Change framework to systematically evaluate the immediate, intermediate, and long-term outcomes of this university's interventions. It assesses the transformative impact of these changes by integrating secondary data with qualitative insights, including focus group discussions with twelve students and semi-structured interviews with three supervisors. The study reveals that while this university has made substantial progress in achieving short-term goals, these reforms have not uniformly benefited all student categories, presenting distinct challenges and opportunities for stakeholders. Consequently, it advocates for diversifying the student composition and emphasizes inclusive pedagogical strategies to facilitate high-quality doctoral education. Importantly, this research extends beyond this university, promoting a balanced mix of student profiles and a holistic approach to shaping effective policies and practices within doctoral admission, essential for navigating global competition.

Medicaid expansion and opioid prescriptions: Evidence from the Medical Expenditure Panel Survey.

Evidence is mixed on whether increased access to insurance, specifically through the ACA's Medicaid expansion, exacerbated the opioid public health crisis through increased opioid prescribing. Using survey data on retail prescription drug fills from 2008 to 2019, we did not find a significant relationship between Medicaid expansion and opioid prescribing in the newly eligible Medicaid population. It may be that the dangers of opioids were known well enough by the time of the Medicaid expansion that lack of access to care was no longer a binding constraint on opioid prescription receipt.

The revolution next door.

This paper explores the cascading influence of revolutionary moments on democracy and inequality, not at home, but across borders. We use data on revolutions and other social upheavals over the past 120 years and examine their cross-national impact on a range of variables in neighboring countries. Engaging with debates on whether substantial democracy and equality increases require extraordinary circumstances, our research investigates whether revolutionary activities induce consequential spillovers, such as policy concessions from elites in neighboring contexts. In exploring spillover effects, the paper examines how significant events in one nation influence social life in adjacent ones. It encompasses an analysis of 171 countries over two centuries, connecting data on revolution with democracy and equality metrics, and hypothesizing that elite fear of revolutionary contagion may necessitate democracy and equality concessions to mitigate potential uprisings. Findings suggest neighboring revolutions positively impact domestic democracy and equality levels. We observe significant increases in an index of democracy and two indices of economic egalitarianism, although one of the egalitarianism measures is robust to all model specifications. Additionally, we find that isolated "protest-led ousters" can moderately increase suffrage and one of our indices of egalitarianism, while coups do not seem to impact democracy or inequality variables. By examining various upheaval types and outcomes across time and space, the study illuminates the causal relationship between global mobilizations and local changes, providing insights into how global events inform domestic outcomes.

Psychiatric Experiments with "Community" Under Dictatorship and Authoritarianism: The Case of the Protected Commune Experience, 1980-1989.

In Chile, a long and oppressive military regime (1973-1990) dismantled emergent initiatives for the deinstitutionalisation of psychiatric care, imposing a neoliberal constitution that opened public services to market forces and limited the state's role in health and social care. After being associated with communism and socialism, community-based mental health work was banned, and socialist psychiatrists were silenced through torture or exile. However, some therapeutic initiatives persisted, such as the "Protected Commune" (PC) initiative within the El Peral psychiatric asylum. The PC attempted to mimic a real town inside the asylum's gated perimeter. It featured an ecumenical chapel, a school, and various "council" departments like recreation, education, waste, economy, and health. Paths received names, wards became districts, and patients and workers were assigned new, democratic roles, all while the authoritarian regime entirely controlled the "outside" world. The initiative ceased with the return of democracy in 1990. Deemed an eccentric and negligible episode, the PC is often seen as an interruption to the radical community-based experiences of the pre-dictatorial era. Drawing on archival research and oral history interviews with participants, this paper examines how the PC harnessed the notion of community to navigate the complex socio-political landscape of the dictatorship. Differing from established accounts of the political uses of psychiatry under authoritarianism, the study positions the PC as a prism for understanding the contradictory ways in which the idea of 'community' has been able to transcend radically opposed social and political regimes, becoming a core feature in the vocabulary of mental health reform, despite its ambiguities.

Public hospital reform, family health consumption and health inequality: evidence from China Family Panel Studies.

Background: In 2017, China launched a comprehensive reform of public hospitals and eliminated drug markups, aiming to solve the problem of expensive medical treatment and allow poor and low-income people to enjoy basic health opportunities. This study attempts to evaluate the policy impact of public hospital reform on the health inequality of Chinese residents and analyze its micro-level mechanism from the perspective of household consumption structure. Studying the inherent causal connection between public hospital reform and health inequality is of paramount significance for strengthening China's healthcare policies, system design, raising the average health level of Chinese residents, and achieving the goal of ensuring a healthy life for individuals of all age groups. Methods: Based on the five waves of data from the China Family Panel Studies (CFPS) conducted in 2012-2020, We incorporates macro-level statistical indicators such as the time of public hospital reforms, health insurance surplus, and aging, generating 121,447 unbalanced panel data covering 27 provinces in China for five periods. This data was used to explore the impact of public hospital reform on health inequality. Logical and empirical tests were conducted to determine whether the reform, by altering family medical care and healthy leisure consumption expenditures, affects the micro-pathways of health inequality improvement. We constructed a two-way fixed model based on the re-centralized influence function (RIF_CI_OLS) and a chained mediation effects model to verify the hypotheses mentioned above. Results: Public hospital reform can effectively improve the health inequality situation among Chinese residents. The reform significantly reduces household medical expenses, increases healthy leisure consumption, promotes the upgrading of family health consumption structure, and lowers the health inequality index. In terms of indirect effects, the contribution of the increase in healthy leisure consumption is relatively greater. Conclusion: Public hospital reform significantly alleviates health inequality in China, with household health consumption serving as an effective intermediary pathway in the aforementioned impact. In the dual context of global digitization and exacerbated population aging, enhancing higher education levels and vigorously developing the health industry may be two key factors contributing to this effect.

A self-assessment maturity matrix to support large-scale change using collaborative networks in the New Zealand health system.

BACKGROUND: A maturity matrix can be a useful tool for organisations implementing large-system transformation (LST) initiatives in complex systems. Insights from implementation of a local LST initiative using collaborative networks, known as Alliances, highlighted a tool was needed to help health system leaders prompt discussions on how and where to focus their change efforts. In the New Zealand (NZ) health system, Alliances were introduced to integrate the planning and delivery of health care between primary and hospital care. METHODS: The aim of this research was to use insights from Alliance members to develop a learning tool that collaborative networks could use to assess and improve their readiness for change. We constructed a maturity matrix using the knowledge of senior NZ health system leaders, in a workshop setting. The maturity matrix was empirically tested and refined with three Alliances and with feedback from the NZ Ministry of Health Maori Health Strategy and Policy team. RESULTS: The maturity matrix described the 10 key elements that had been found to support successful implementation of LST initiatives in the NZ health system, along with success indicators and different stages of maturity from beginning to excellence. Testing of the maturity matrix with three Alliances suggested that it functioned as a learning tool and stimulated collective thinking and reflection. The Maori Health Strategy and Policy team commented on the importance of such a tool to increase health system leaders' responsiveness to improving Maori health outcomes. Comparisons with similar international matrices revealed common elements with ours. A strength of our maturity matrix is that it is specific to the NZ context and is the first practical tool to implement large-scale change in the health system that incorporates principles of the Government's treaty with Maori, the indigenous people of NZ. CONCLUSIONS: Through a regular self-assessment process, use of the maturity matrix may create feedback loops to support deliberate learning and knowledge sharing for senior health system leaders and collaborative networks. The maturity matrix fills an important gap in the NZ health system and contributes to implementation science literature internationally.

Nursing Regulation Literature in Canada: Protocol for a Scoping Review.

BACKGROUND: Significant reforms are occurring in health practitioner regulation across Canada. Within the nursing profession, growing workforce challenges and health system demands have accelerated the pace of changes to nursing regulation policies and practices. There is significant political investment to modernize and harmonize nursing regulation across Canada, and evidence is needed to guide regulatory decision-making. To better understand the current state of scholarship and the gaps that exist, a comprehensive understanding of the available literature informing nursing regulation in Canada is first warranted. OBJECTIVE: The objective of this scoping review is to examine the nature, extent, and range of literature focused on nursing regulation in Canada. METHODS: The review will be conducted in accordance with the Joanna Briggs Institute guidelines for scoping reviews. We will search electronic databases, including Ovid MEDLINE, Ovid EMBASE, CINAHL, Scopus, and Web of Science Core Collection. We will also search for grey literature using the websites of Canadian nursing regulatory bodies, nursing organizations, and other leading Canadian regulatory organizations. No limitations will be placed on the year of publication. The review will include papers that explore nursing regulation in Canada, including topics such as education program accreditation or approval, licensure, standards of practice and code of conduct/ethics development and enforcement, continuing competence, discipline and conduct, regulatory models, governance, and reform. We will extract data using a predeveloped tool. Data will be analyzed using descriptive statistics and conventional content analysis. RESULTS: A preliminary search in Ovid MEDLINE was undertaken on December 7, 2023, and a full search was conducted in 5 academic databases on March 15, 2024. Findings will be presented using evidence tables and a narrative summary. Reporting will follow the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) guidelines. This scoping review is expected to be completed in early 2025. CONCLUSIONS: The results will be disseminated through conference presentations and a publication in a peer-reviewed journal. The findings will provide a comprehensive overview of the state of nursing regulation literature across Canada and inform the development of a focused research agenda.

Rape Myths and Verdict Systems: What Is Influencing Conviction Rates in Rape Trials in Scotland?

The Scottish verdict system includes three verdicts: 'guilty', 'not guilty' and 'not proven'. Politicians propose that the three-verdict system is partially to blame for the low conviction rate of rape, whereas research suggests that rape myths may be having a larger impact. To test the effects of varying verdict systems (guilty, not guilty and not proven; guilty and not guilty; a series of proven and not proven verdicts) and rape myths on juror verdicts. A total of 180 participants answered questions regarding their acceptance of rape myths using the Acceptance of Modern Myth and Sexual Aggression (AMMSA) scale. They then watched a staged rape trial filmed in a real courtroom and reached a verdict. Participants also provided longer-form answers on which thematical analysis was conducted. The main findings are as follows: (1) The special verdict system leads to a higher conviction rate than the other systems when rape myth acceptance is controlled for. (2) The higher the rape myth acceptance, the more favourably the accused was perceived and the less favourably the complainer was perceived.

Evaluating the effect of health insurance reform on health equity and financial protection for elderly in low- and middle-income countries: evidences from China.

BACKGROUND: To achieve Universal Health Coverage (UHC), China have implemented health system reform to expend health coverage and improve health equity. Scholars have explored the implementing effect of this health reform, but gaps remained in health care received by elderly. This study aims to assess the effect of implementing health insurance payment reform on health care received by elderly, as well as to evaluate its effect on cost sharing to identify whether improve financial protection of elderly under this reform. METHODS: We identified hospitalization of 46,714 elderly with cerebral infarction from 2013 to 2023. To examine the determinant role played by DRGs payment reform in healthcare for elderly and their financial protection, this study employs the OLS linear regression model for analysis. In the robustness checks, we validated the baseline results through several methods, including excluding the data from the initial implementation of the reform (2021), reducing the impact of the pandemic, and exploring the group effects of different demographic characteristics. RESULTS: The findings proposed that implementing DRGs payment reduces drug expenses but increases treatment expense of chronic disease for elderly in China. This exacerbates healthcare costs for elderly patients and seems to be contrary to the original purpose of health care reform. Additionally, the implementation of DRGs payment reduced the spending of medical insurance fund, while increased the out-of-pocket of patients, revealing a shift in health care expenses from health insurance fund to out-of-pocket. CONCLUSIONS: This study shares the lessons from China's health reform and provides enlightenment on how to effective implement health reform to improve health equity and achieve UHC in such low- and middle-income countries facing challenges in health financing.

Environmental judicial reform and corporate investment behavior - Based on a quasi-natural experiment of environmental courts.

Ensuring the effectiveness of environmental legislation and regulations necessitates enhancing the professional caliber of the environmental judiciary. Utilizing a multi-period difference-in-differences model, we explore the impact of environmental judicial reforms, exemplified by the establishment of environmental courts, on corporate investment behavior. We find that firms in regions with established environmental courts significantly increase their environmental investments and productive investments, while financial investments remain unaffected. Mechanism testing reveals that the environmental court affects corporate investment by strengthening local government environmental enforcement and promoting public environmental participation. Furthermore, the marginal effect of environmental courts is more pronounced in regions with fewer environmental regulations and lower economic development levels, as well as in state-owned enterprises. Compared to collegiate benches, environmental resources judicial tribunals exert a greater influence on corporate investment behavior. This study adds to the micro-economic analysis of environmental judiciary by providing empirical evidence on how formal institutional frameworks impact corporate investment behavior.

Healthcare workers' views on decentralized primary health care management in Lesotho: a qualitative study.

BACKGROUND: Lesotho experienced high rates of maternal (566/100,000 live births) and under-five mortality (72.9/1000 live births). A 2013 national assessment found centralized healthcare management in Ministry of Health led to fragmented, ineffective district health team management. Launched in 2014 through collaboration between the Ministry of Health and Partners In Health, Lesotho's Primary Health Care Reform (LPHCR) aimed to improve service quality and quantity by decentralizing healthcare management to the district level. We conducted a qualitative study to explore health workers' perceptions regarding the effectiveness of LPHCR in enhancing the primary health care system. METHODS: We conducted 21 semi-structured key informant interviews (KII) with healthcare workers and Ministry of Health officials purposively sampled from various levels of Lesotho's health system, including the central Ministry of Health, district health management teams, health centers, and community health worker programs in four pilot districts of the LPHCR initiative. The World Health Organization's health systems building blocks framework was used to guide data collection and analysis. Interviews assessed health care workers' perspectives on the impact of the LPHCR initiative on the six-health system building blocks: service delivery, health information systems, access to essential medicines, health workforce, financing, and leadership/governance. Data were analyzed using directed content analysis. RESULTS: Participants described benefits of decentralization, including improved efficiency in service delivery, enhanced accountability and responsiveness, increased community participation, improved data availability, and better resource allocation. Participants highlighted how the reform resulted in more efficient procurement and distribution processes and increased recognition and status in part due to the empowerment of district health management teams. However, participants also identified limited decentralization of financial decision-making and encountered barriers to successful implementation, such as staff shortages, inadequate management of the village health worker program, and a lack of clear communication regarding autonomy in utilizing and mobilizing donor funds. CONCLUSION: Our study findings indicate that the implementation of decentralized primary health care management in Lesotho was associated a positive impact on health system building blocks related to primary health care. However, it is crucial to address the implementation challenges identified by healthcare workers to optimize the benefits of decentralized healthcare management.

Demand and Supply Drivers of Medicare and Non-Medicare Health Spending: An Analysis of U.S. States, 1991-2019.

For the last four decades, policymakers have attempted to control the United States's high health care costs by reducing patients' demand for care (e.g., by imposing managed-care restrictions or high costs on patients at the time of use). Yet studies based mostly on data from the public Medicare program, which covers mostly elderly Americans, suggest that supply (e.g., number of physicians or hospital beds) rather than demand drives aggregate service use and, hence, costs. Using variation between U.S. states in per enrollee Medicare spending versus per capita spending of all other (non-Medicare) individuals, we find that greater supply boosts costs for the entire population. Furthermore, we find that factors that suppress demand in the non-Medicare population do reduce non-Medicare health care spending, but simultaneously increase Medicare spending. This suggests that for a given supply of medical resources, suppressing demand for one group of patients may produce a compensatory increase in provision of care to those whose demand has not been suppressed. Health planning to assure adequate medical resources where they are needed while preventing excess supply where it is duplicative and wasteful is likely a more effective cost control strategy than the imposition of managed-care restrictions or imposing higher costs onto patients seeking care.

Donor conception, direct-to-consumer genetic testing, choices, and procedural justice: an argument for reform of the Human Fertilisation and Embryology Act 1990.

In this article, using theories of procedural justice and 'slow violence', we consider potential reform of the Human Fertilisation and Embryology Act 1990. Our theoretical discussion is underpinned by findings from the ConnecteDNA project, exploring how people affected by donor conception experience direct-to-consumer genetic testing (DTCGT). The negative impacts of DTCGT, especially shock discoveries about the circumstances of someone's conception in adulthood, are linked to donor anonymity, and how its continued protection is experienced as a barrier to the rights and agency of donor-conceived people. We focus on two key issues relating to the donor information access process set out in section 31ZA of the 1990 Act. The first is that it excludes certain cohorts of donor-conceived people, creating inequalities of access to donor information. The second is the impact of the use of DTCGT to search for that information. We discuss what a procedurally just process of law reform would look like, concluding that, whatever (prospective) approach to donor anonymity is taken, the donor information access process should be the same for all donor-conceived people. We thus argue that, even were the status quo to be maintained, reform of the donor information access process with retrospective effect would be required.

Positive impacts of green finance on environmental protection investment: Evidence from green finance reform and innovations pilot zone.

After long-term development, the global economic level has improved significantly, but environmental issues generated by early extensive development seriously threaten the survival of human beings. China, in particular, urgently needs to promote sustainable development through green finance policies. For this reason, this paper regards the 2017 eight pilot zones in five provinces for green finance reform and innovations (GFRIs) as a quasi-natural experiment, and explores whether it can encourage investment in environmental protection in heavily polluting enterprises by using difference-in-differences-in-differences (DDD) model. The paper finds that: First, GFRIs can bolster investment in environmental protection in heavy polluting enterprises. The results remain consistent after several robustness checks, covering the placebo test, PSM-DID test and so on. Second, mechanism tests find that the policy promotes environmental protection investment by alleviating financing constraints and cutting financing costs. Third, heterogeneity analysis shows that the promotion effect of GFRIs on environmental protection investment is more pronounced for provinces with higher percentages of secondary industry GDP, large-scale enterprises, and enterprises with better ESG management. This paper demonstrates the beneficial influence of GFRIs on promoting the transformation of heavy polluting enterprises and provides suggestions for the improvement of such policies.

Value-based healthcare payment models: a wolf in sheep's clothing for patients and clinicians.

Value-based healthcare payment models are an alternative insurance payment system that compensates healthcare providers based on their patients' outcomes rather than the individual services healthcare workers provide. This shift from the current fee-for-service model that predominates our medical system has received renewed popularity and attention within organized medicine such as the American Medical Association. Advocates believe that this new payment model will address many of the unsolved issues in healthcare such as medical waste and unsustainable healthcare costs. In practice, however, this model is plagued with a myriad of unresolved issues of its own. In this commentary, we outline these issues and suggest that the intentions of those advocating for value-based payment models are either misguided or disingenuous. We then offer solutions that preserve our current fee-for-service model while making necessary changes that will benefit both physicians and patients nationwide.

Male rape: survivors, support and the law in late twentieth-century England and Wales.

Until 1994, men were not recognized legally as victims of rape in England and Wales. This article explores the history of male survivors of rape there, establishing the uneven patchwork of support services available to them prior to 1994. It argues that a growing psychiatric literature which studied male survivors of sexual violence was a major factor in convincing lawmakers to include men as potential victims of rape in updated sexual offence legislation. Other medical professionals played key roles in bringing male survivors to police attention, but psychiatric research was most influential in changing the policy agenda in this arena.

American Shoulder & Elbow Surgeons Perspectives on Political Advocacy.

BACKGROUND: Physician involvement in political advocacy has become increasingly important in recent years. This study aims to explore the types of involvement and barriers to involvement in political advocacy among American Shoulder and Elbow Surgeons (ASES) members, identify issues considered most important by ASES members, and assess demographic factors that might correlate with involvement in political advocacy efforts among ASES members. METHODS: This survey was conducted by the ASES Political Advocacy Committee over a two-week period in June 2021. The survey collected demographic information including sex, ethnicity, years in practice, practice type, political affiliation, and level of current involvement in political advocacy. Additional questions consisted of thoughts regarding current health care policy issues and the role of the American Academy of Orthopaedic Surgeons (AAOS)/ASES regarding such policy issues. RESULTS: We received 297 responses for a total response rate of 27%. Of those who responded, 24.6% identified as Democrat, 33% identified as Republican, and 42.4% identified as Independent. There was no difference in political affiliation between membership groups. Physician Reimbursement (82%), Medical Liability Reform (50%), and Physician Ownership (50%) were the most important issues identified among respondents. Physician Ownership, Physician Reimbursement and GME and Student Loan Reform were most important to those in early practice, while Quality and Research was most important to those with greater than 25 years of practice experience. CONCLUSION: There is strong agreement among surgeons regarding the most important political advocacy issues. The efforts of the AAOS and ASES should focus on these areas. Additionally, the vast majority of respondents felt that advocacy efforts had a positive impact on patients and surgeons.
