    土壤碳库在应对气候变化中的重要作用已得到广泛认可。毛竹(Phyllostachyspubescens)是中国南方经济上重要的竹种;但是,由于劳动力成本上升和日益严格的环境政策等因素,莫索竹林最近被废弃了。本研究旨在研究遗弃对毛竹林结构因子和土壤有机碳(SOC)储量的影响。我们调查了不同持续时间的集约化经营或废弃的毛竹林,并测量了森林结构特征,矿物特性,土壤养分,和其他土壤性质。尽管放弃并没有显着影响乳房高度的高度和直径,它增加了茎秆密度,生物量,和SOC股票。SOC存量的驱动因素取决于土壤深度,主要受土壤特性介导的碳分解控制。在表土中,矿物保护和土壤全氮(TN)对SOC储量有显著影响;在底土,土壤TN是SOC存量的主要驱动因素。由于底土和表土之间SOC储量的控制因素不同,应该更多地注意地基。总的来说,这些发现完善了我们对与毛竹林废弃相关的结构特征和SOC种群的理解,为这些森林的后续管理提供参考。
    The important role of soil carbon pools in coping with climate change has become widely recognized. Moso bamboo (Phyllostachys pubescens) is an economically important bamboo species in South China; however, owing to factors such as rising labor costs and increasingly stringent environmental policies, Moso bamboo forests have recently been abandoned. The present study aimed to investigate the effects of abandonment on structural factors and soil organic carbon (SOC) stocks in Moso bamboo forests. We investigated Moso bamboo forests subjected to intensive management or abandonment for different durations and measured forest structural characteristics, mineral properties, soil nutrients, and other soil properties. Although abandonment did not significantly affect the height and diameter at breast height, it increased culm densities, biomass, and SOC stocks. The drivers of SOC stocks depended on soil depth and were mainly controlled by carbon decomposition mediated by soil properties. In the topsoil, mineral protection and soil total nitrogen (TN) exerted significant effects on SOC stocks; in the subsoil, soil TN was the main driver of SOC stocks. As the controlling factors of SOC stocks differed between the subsoil and topsoil, more attention should be paid to the subsoil. Overall, these findings refine our understanding of the structural characteristics and SOC stocks associated with Moso bamboo forest abandonment, serving as a reference for the follow-up management of these forests.

    这种在秘鲁背景下对死亡的人种学探索借鉴了他们的家人和州老年人在利马无家可归者收容所中被遗弃的田野调查,秘鲁。我研究了塑造该机构人们在社会和身体上死亡方式的条件和当地力量。我的论点是,这个长期护理机构中的人们一生都生活在边缘,通常,最终导致他们的家人不相关的死亡,该机构的其他居民,和秘鲁国家。在这个避难所,以无关紧要的方式死亡意味着没有家庭成员的陪伴而死亡,并从庇护他们的机构那里得到贫穷和有缺陷的照顾。
    This ethnographic exploration of death in the Peruvian context draws on fieldwork among abandoned-both by their families and the state-older adults in a shelter for the homeless in Lima, Peru. I examine the conditions and local forces that shape the ways people at this institution socially and physically die. My argument is that people in this long-term care facility who have lived entire lives on the margins, usually, end up having irrelevant deaths to their families, other residents of the institution, and the Peruvian state. At this shelter, dying in an irrelevant way means dying without companionship from family members and receiving poor and flawed care from the institution that shelters them.

    爱沙尼亚的半天然草原(SNGL)受到遗弃的威胁。这种威胁导致人们对草原社区内生物多样性退化的担忧。尽管在这种情况下经济激励措施具有很高的相关性,尚未研究此类激励措施如何影响土地管理者关于SNGL农业使用的决策。为了获得其对决策的社会生态影响,我们开发了特定区域的农业情景(补偿支付,牲畜容量,嘿出口,和生物能源生产)和跨学科建模方法,使通过土地管理者对各种经济条件的反应来模拟农业土地利用变化成为可能。通过这种方法,我们发现一些经济因素阻碍了SNGL的使用:牛肉生产的适度盈利能力,劳动力短缺,以及地膜覆盖相对较高的盈利能力。我们观察到SNGL与繁殖和饲养鸟类的栖息地适宜性之间存在正相关关系。然而,由于SNGL的高维护成本,建模结果表明,通过公共预算增加SNGL的使用会导致挤出效应,即,区域农业市场一体化的恶化。这项研究强调需要采取旨在具有成本效益的政策措施,SNGL的劳力高效管理实践。
    Semi-natural grasslands (SNGLs) in Estonia are threatened by abandonment. This threat is leading to concerns about the degradation of biodiversity within grassland communities. Despite the high relevance of economic incentives in this context, how such incentives influence land managers\' decision-making regarding the agricultural use of SNGLs has not been investigated. To obtain its socio-ecological implications for policy-making, we developed regionally specific agricultural scenarios (compensation payments, livestock capacity, hey export, and bioenergy production) and an interdisciplinary modelling approach that made it possible to simulate agricultural land use changes through land managers\' responses to varied economic conditions. Through this approach, we found that some economic factors hampered the use of SNGLs: the moderate profitability of beef production, labour shortages, and the relatively high profitability of mulching. We observed a positive relationship between SNGLs and habitat suitability for breeding and feeding birds. However, due to the high maintenance costs of SNGLs, the modelling results indicated that increasing the use of SNGLs through public budgets caused crowding-out effects, i.e., the deteriorating market integration of regional agriculture. This study emphasises the need for policy measures aimed at cost-effective, labour-efficient management practices for SNGLs.

    早期发现镰状细胞病(SCD)对于降低受影响儿童的死亡率至关重要。苏里南目前缺乏针对SCD的新生儿筛查计划(NSP)。我们执行了一个试点计划来评估这一计划的可扩展性。从五个出生中心收集干燥的血斑并进行电泳分析。程序的可扩展性是使用不采用来评估的,放弃,扩大规模,传播,和可持续性框架。跨越六个领域的挑战(疾病,技术,价值主张,采用者系统,organization,和社会制度),被分层分类得很简单?,复杂?,还是复杂的?事实证明,执行主要面临复杂挑战的方案是困难的,而在主要复杂领域的方案可能无法实现。在5185例成功筛查的新生儿中,有33例(0.64%)检测到SCD。大多数领域被分类为简单或复杂。确定了苏里南的疾病检测和筛查技术适用性,有利的父母接受。方案实施只需要医务人员进行少量的例行调整。复杂的挑战包括依赖外部供应商进行技术维护,确保受影响的新生儿及时获得专门的儿科护理,并确保可持续的财务资金。扩大规模具有挑战性但可行,特别是有针对性地关注已确定的复杂挑战。
    The early detection of sickle cell disease (SCD) is vital to reduce mortality among affected children. Suriname currently lacks a newborn screening programme (NSP) for SCD. We performed a pilot programme to evaluate the scalability of such an initiative. Dried blood spots were collected from five birth centres and subjected to electrophoresis analysis. The programme scalability was evaluated using the non-adoption, abandonment, scale-up, spread, and sustainability framework. Challenges across six domains (illness, technology, value proposition, adopter system, organisation, and societal system), were categorised hierarchically as simple 😊, complicated 😐, or complex 😢. It has been proven that implementing programmes with mainly complicated challenges is difficult and those in mainly complex areas may be unachievable. SCD was detected in 33 of 5185 (0.64%) successfully screened newborns. Most of the domains were classified as simple or complicated. Disease detection and technology suitability for screening in Suriname were confirmed, with favourable parental acceptance. Only minor routine adjustment was required from the medical staff for programme implementation. Complex challenges included a reliance on external suppliers for technical maintenance, ensuring timely access to specialised paediatric care for affected newborns, and securing sustainable financial funding. Scaling up is challenging but feasible, particularly with a targeted focus on identified complex challenges.

    Restoring ecosystems is an imperative for addressing biodiversity loss and climate change, and achieving the targets of the Kunming-Montreal Global Biodiversity Framework. One form of restoration, rewilding, may have particular promise but may also be precluded by requirements for other forms of land use now or in the future. This opportunity space is critical but challenging to assess. We explored the potential area available for rewilding in Great Britain until the year 2080 with a multisectoral land-use model with several distinct climatic and socioeconomic scenarios. By 2080, areas from 5000 to 7000 km2 were either unmanaged or managed in ways that could be consistent with rewilding across scenarios without conflicting with the provision of ecosystem services. Beyond these areas, another 24,000-42,000 km2 of extensive upland management could provide additional areas for rewilding if current patterns of implementation hold in the future. None of these areas, however, coincided reliably with ecosystems of priority for conservation: peatlands, ancient woodlands, or wetlands. Repeatedly, these ecosystems were found to be vulnerable to conversion. Our results are not based on an assumption of support for or benefits from rewilding and do not account for disadvantages, such as potential losses of cultural landscapes or traditional forms of management, that were beyond the modeled ecosystem services. Nevertheless, potential areas for rewilding emerge in a variety of ways, from intensification elsewhere having a substantial but inadvertent land-sparing effect, popular demand for environmental restoration, or a desire for exclusive recreation among the wealthy elite. Our findings therefore imply substantial opportunities for rewilding in the United Kingdom but also a need for interventions to shape the nature and extent of that rewilding to maintain priority conservation areas and societal objectives.
    Una evaluación del potencial futuro de la resilvestración en el Reino Unido Resumen La restauración de ecosistemas es urgente para abordar la pérdida de biodiversidad y el cambio climático, así como para lograr los objetivos del Marco Mundial de Biodiversidad de Kunming‐Montreal. Un método de restauración, la resilvestración, puede ser particularmente prometedor, aunque también puede ser excluido por los requerimientos para otras formas de uso de suelo actuales o en el futuro. Este espacio de oportunidad es crítico, pero también un reto para evaluar. Exploramos el área potencial disponible para el resilvestrado en Gran Bretaña hasta el año 2080 con un modelo multisectorial de uso de suelo con varios escenarios climáticos y socioeconómicos. Para este año, las áreas entre 5,000 y 7,000 km2 no estaban gestionadas o lo estaban, pero de manera que podían ser consistentes con el resilvestrado de los escenarios sin conflictuar el suministro de servicios ambientales. Más allá de estas áreas, otros 24,000‐42,000 km2 de gestión extensiva tierra arriba podrían proporcionar áreas adicionales para el resilvestrado si los patrones actuales de implementación siguen en pie en el futuro. Sin embargo, ninguna de estas áreas coincidió de manera confiable con los ecosistemas de prioridad para la conservación: las turberas, bosques antiguos o humedales. Estos ecosistemas aparecieron varias veces como vulnerables a la conversión. Nuestros resultados no están basados en una suposición de apoyo para o los beneficios de la resilvestración y no consideran las desventajas, como la pérdida potencial de paisajes culturales o las maneras tradicionales de manejo, que estaban fuera del alcance de los servicios ambientales modelados. Sin embargo, las áreas potenciales para el resilvestrado emergen en una variedad de formas, desde la intensificación en otros lugares con un efecto de ahorro de tierras sustancial pero inadvertido, la demanda popular por la restauración ambiental o el deseo de una recreación exclusiva entre la elite acaudalada. Por lo tanto, nuestros descubrimientos implican una oportunidad sustancial para la resilvestración en el Reino Unido, aunque también una necesidad de intervenciones para moldear la naturaleza y la extensión de ese resilvestrado para mantener las áreas prioritarias de conservación y los objetivos sociales.
    为应对生物多样性丧失和气候变化, 并实现《昆明‐蒙特利尔全球生物多样性框架》目标, 一项当务之急是生态系统的恢复。再野化作为生态系统恢复的一种方式, 可能具有独特前景, 但也可能因当下或未来其他土地利用形式的需求而被排除在外。因此, 这一机会空间至关重要, 而其评估也面临挑战。本研究利用一个多部门土地利用模型, 结合多种气候和社会经济的不同情景, 分析了大不列颠岛至2080年可用于再野化的潜在区域。结果显示, 到2080年, 有5000到7000平方公里的区域或处于无人管理状态, 或其管理方式与各种情景下的再野化条件一致, 不会与提供生态系统服务发生冲突。除这些区域外, 如果未来能够维持当前的实施模式, 则还有24,000‐42,000平方公里的广阔的高地管理区域可用于再野化。然而, 这些区域都没有与优先保护的生态系统(泥炭地、古林地和湿地)很好地重合。此外, 这些生态系统很容易发生转换。我们的研究结果并非基于支持再野化或从再野化中获益的假设, 也没有考虑到不利因素, 如文化景观或传统管理形式的潜在丧失, 这些都超出了模拟生态系统服务的范围。尽管如此, 可用于再野化的潜在区域还是有多种来源方式, 如其他地区的集约化无意产生的大规模土地节约效应、民众对环境恢复的需求, 或富裕的精英阶层对专属娱乐的渴望。因此, 我们的研究结果表明, 英国存在大量再野化机会, 但同时也需要采取干预措施来确定再野化的性质和范围, 以维持优先保护区域和社会目标。【翻译: 胡怡思; 审校: 聂永刚】.

    已经描述了许多关于早期放弃母乳喂养的因素,包括健康素养(HL)。本研究的目的是分析早期放弃母乳喂养(<6个月)的相关因素。这项前瞻性多中心研究调查了产后6个月母乳喂养的持续时间,并于2021年1月至2023年1月在西班牙的四个不同地区进行。共有275名妇女参加了这项研究,重点关注孕产妇HL和产科实践。从出院(n=224,81.5%)到产后6个月(n=117,42.5%)观察到母乳喂养率下降。Cox回归分析显示,HL水平不足,劳动期间缺乏动员,和引产与早期停止母乳喂养显著相关(分别为p=0.022,p=0.019和p=0.010).结果强调,具有足够HL的女性早期放弃母乳喂养的风险降低了32%。相比之下,分娩和引产期间的动员与这种风险减少32.4%和增加53.8%有关,分别。这些发现强调了在处理母乳喂养持续时间时考虑产科和HL因素的重要性。指出教育和围产期保健干预的机会。
    Numerous factors concerning early breastfeeding abandonment have been described, including health literacy (HL). This study\'s objective was to analyze factors related to early breastfeeding abandonment (<6 months). This prospective multicentric study examined the duration of breastfeeding at 6 months postpartum and was conducted in four different regions of Spain from January 2021 to January 2023. A total of 275 women participated in this study, which focused on maternal HL and obstetric practices. A decrease in the breastfeeding rate was observed from hospital discharge (n = 224, 81.5%) to the sixth month postpartum (n = 117, 42.5%). A Cox regression analysis revealed that inadequate HL levels, lack of mobilization during labour, and induced labour were significantly associated with early breastfeeding cessation (p = 0.022, p = 0.019, and p = 0.010, respectively). The results highlight that women with adequate HL had a 32% lower risk of early breastfeeding abandonment. In comparison, mobilization during labour and induction of labour were linked to a 32.4% reduction and a 53.8% increase in this risk, respectively. These findings emphasize the importance of considering obstetric and HL factors when addressing the breastfeeding duration, indicating opportunities for educational and perinatal care interventions.

    地中海土地系统在农业土地利用和实践方面正在发生重大变化。地中海盆地农业区的位置和性质正在发生变化,因为当地和整个盆地都出现了一系列紧张局势和机遇。该数据集提供了主要的短期土地系统动态(2005-2015年)及其在整个地中海盆地上的位置。该数据集基于现有的土地利用图和有关农业表面分布的可用数据,它是通过对两个分析数据(2005年和2015年)的土地系统进行分类处理以及随后在两个获得的地图之间进行变化检测而获得的。它以2公里空间分辨率的像素覆盖了所有地中海生物气候区,协调盆地北部和南部的信息。我们确定了不同类型的变化,就表面而言,最相关的是:(1)从混合农业到专门的果园;(2)从农业区到城市和/或近城区;(3)从农林业到耕地系统,和(4)从主要的裸露土壤到农业区。这些数据可用于进一步分析,以评估潜在的轨迹,以及观察到的动态对生物多样性和生态系统服务提供的影响,以及食物系统的组织。
    Mediterranean land systems are undergoing significant changes in terms of agricultural land use and practices. The location and nature of agricultural areas in the Mediterranean basin are changing following a set of tensions and opportunities taking place both locally and in the entire basin. This dataset presents the main short-term land system dynamics (2005-2015) and their location on the whole Mediterranean basin. The dataset is based on existing land use map and available data about agricultural surface distribution, and it is obtained through a classification process of the land systems on the two analyzed data (2005 and 2015) and a subsequent change detection between the two obtained maps. It covers all the Mediterranean bioclimatic area in pixels of 2 km spatial resolution, harmonizing information from the northern and southern side of the basin. We identified different types of changes, and the most relevant in terms of surfaces are: (1) from mixed agriculture to specialized fruit groves; (2) from agricultural areas to urban and/or periurban areas; (3) from agroforestry to arable systems, and (4) from predominantly bare soils to agricultural areas. This data can be used for further analysis to assess underlying trajectories, and the impact of the observed dynamics on biodiversity and the provision of ecosystem services, as well as on the organization of the food system.

    背景:在生命早期阶段造成的不同类型的压力会增加风险,在成年动物和人类中,发展出不安的情绪相关行为,如饮食亢进或抑郁。早期应激(ELS)成人表现出下丘脑-垂体-肾上腺(HPA)轴的过度活跃,这是与情绪障碍相关的危险因素。然而,在经历过ELS的成年人中,饮食过多(17%)和抑郁症(50%)的患病率是可变的,这表明大自然,强度,压力的慢性性决定了这些个体发展的具体行为改变。
    方法:我们分析了皮质酮血清水平,Crh,GR,下丘脑室旁核Crhr1基因表达,杏仁核,由于它们在经历母体分离(MS)或有限筑巢材料(LNM)应激的成年大鼠中对HPA轴的调节作用,以及与促肾上腺皮质激素释放激素(CRH)途径功能以及饮食过多和抑郁症发展相关的相同区域的血清素能系统活性。
    结果:产妇护理的改变引起MS和LNM成人对急性应激无反应或反应过度的HPA轴功能,分别。杏仁核和海马CRH系统的差异变化似乎可以补偿MS中下丘脑脱敏糖皮质激素受体(GR)的变化或LNM中的超敏反应。然而,这两种成年动物在进行强迫游泳试验时都出现了饮食亢进和抑郁样行为,这有助于了解低血和皮质醇血症患者都会出现这些疾病。
    结论:不同的ELS类型诱导神经内分泌,大脑CRH和5-羟基雷公藤甲胺(5-HT)系统的改变可能相互作用,形成类似的适应不良行为。
    BACKGROUND: Different types of stress inflicted in early stages of life elevate the risk, among adult animals and humans, to develop disturbed emotional-associated behaviors, such as hyperphagia or depression. Early-life stressed (ELS) adults present hyperactivity of the hypothalamus-pituitary-adrenal (HPA) axis, which is a risk factor associated with mood disorders. However, the prevalence of hyperphagia (17%) and depression (50%) is variable among adults that experienced ELS, suggesting that the nature, intensity, and chronicity of the stress determines the specific behavioral alteration that those individuals develop.
    METHODS: We analyzed corticosterone serum levels, Crh, GR, Crhr1 genes expression in the hypothalamic paraventricular nucleus, amygdala, and hippocampus due to their regulatory role on HPA axis in adult rats that experienced maternal separation (MS) or limited nesting material (LNM) stress; as well as the serotonergic system activity in the same regions given its association with the corticotropin-releasing hormone (CRH) pathway functioning and with the hyperphagia and depression development.
    RESULTS: Alterations in dams\' maternal care provoked an unresponsive or hyper-responsive HPA axis function to an acute stress in MS and LNM adults, respectively. The differential changes in amygdala and hippocampal CRH system seemed compensating alterations to the hypothalamic desensitized glucocorticoids receptor (GR) in MS or hypersensitive in LNM. However, both adult animals developed hyperphagia and depression-like behavior when subjected to the forced-swimming test, which helps to understand that both hypo and hypercortisolemic patients present those disorders.
    CONCLUSIONS: Different ELS types induce neuroendocrine, brain CRH and 5-hydroxytriptamine (5-HT) systems\' alterations that may interact converging to develop similar maladaptive behaviors.

    Background: Mobility assistive devices (MADs) provide support to older adults to improve their quality of life; however, research shows that as many as 75% of older adults are non-adherent to prescribed MADs. This study investigated the psychosocial factors that predict non-adherence to MADs among older adults.Methods: A sample of Canadian older adult MADs users who resided in a long-term care facility was included. The data was collected using the Psychosocial Impact of Assistive Devices Scale (PIADS), and the Medical Outcomes Study Social Support Survey (mMOS-SS). Data analysis was performed using SPSS 28. Descriptive statistics were used to describe the sample and the study variables. Pearson correlation coefficients were used to evaluate the association between the study variables. Variables that were associated with non-adherence in a univariate analysis were subsequently entered into a multiple regression analysis.Results: The sample comprised 48 residents (26 females and 22 males), with a mean age of 86.8. In the univariate analysis, scores from the three PIADS subscales, namely, Competence, Adaptability, and Self-esteem, and the Social Support scale were significantly correlated with non-adherence (p < 0.05). In the multiple regression analyses, only Self-esteem significantly predicted non-adherence (p < 0.05), and this model explained between 43.5 and 54.3% of the variance in non-adherence.Conclusion: This study revealed that the Self-esteem construct, which includes several concepts related to psychological well-being, was the only significant predictor of non-adherence among the studied sample of older adults. The clinical implications of the findings are subsequently discussed.
    Older adults’ non-adherence to Mobility Assistive Devices (MADs) is a significant problem in Rehabilitation practice.Self-esteem can explain nearly 50% of the variance in the prediction of non-adherence to MADs among older adults.Evaluating client’s Self-esteem is important for clinicians because it helps them determine and predict who will be adherent and who will need further attention.The findings of this research support the use of the Psychosocial Impact of Assistive Devices Scale in clinical practice as a means of building a relationship between the user and a professional.
