    由于需求增加和气候变化的影响,水资源短缺已成为世界许多地区的严峻挑战。农业部门占全球水消费的主要部分,然而,它也具有巨大的节水潜力。最有效的节水方法是种植需水量低的作物,如药用植物(MP),代替需水作物(WDC)。然而,农民的自愿参与,很大程度上受到社会心理驱动因素的影响,对于成功实施大多数节水计划至关重要,需要解决。因此,本文的主要目标是:(1)确定解释农民在培养国会议员而不是WDC方面的意图和行为的决定因素;(2)通过将四个新变量创新性地纳入原始的TPB模型,来检验计划行为理论(TPB)的扩展版本在预测农民对培养国会议员的意图和行为方面的有效性和绩效:感知障碍,道德规范,兼容性,和相对优势。在索贾苏德平原评估了理论框架的适用性,赞詹省,伊朗。结构方程模型的结果表明:(1)农民培养国会议员而不是WDC的意愿受到感知障碍的显著影响。道德规范,主观规范,和感知的行为控制(最强的预测因子);(2)农民在培养MPs而不是WDC方面的行为是通过相对优势预测的,兼容性,和意图(最突出的决定因素)。预测意图和行为的R2值分别为55%和53%,分别。根据结果,提出了一些切实可行的政策来增加研究区的国会议员的培养。
    Water scarcity has become a serious challenge in many parts of the world due to increasing demands and the impacts of climate change. The agriculture sector globally accounts for a major portion of water consumption, yet it also holds substantial potential for water conservation. Among the most effective ways to conserve water is to cultivate low-water-demanding crops, such as medicinal plants (MPs), instead of water-demanding crops (WDC). However, the voluntary participation of farmers, largely influenced by socio-psychological drivers, is crucial for successfully implementing most water conservation programs and needs to be addressed. Therefore, the main objectives of this paper were: (1) to identify the determinants that explain farmers\' intention and behavior in cultivating MPs instead of WDC; and (2) to examine the effectiveness and performance of an extended version of the theory of planned behavior (TPB) in predicting farmers\' intention and behavior toward cultivating MPs by innovatively incorporating four new variables into the original TPB model: perceived barriers, moral norms, compatibility, and relative advantage. The applicability of the theoretical framework was evaluated in the Sojasroud Plain, Zanjan province, Iran. The results of the structural equation modeling revealed that: (1) farmers\' intention to cultivate MPs instead of WDC is significantly influenced by perceived barriers, moral norms, subjective norms, and perceived behavior control (the strongest predictor); and (2) farmers\' behavior in cultivating MPs instead of WDC is predicted by relative advantage, compatibility, and intention (the most prominent determinant). The R2 values for predicting intention and behavior were 55% and 53%, respectively. Based on the results, some practical policies were proposed to increase the cultivation of MPs in the study area.

    在这项研究中,我们着手调查社交媒体对加纳农业推广服务的转化能力。我们采用了定量研究方法,并从374名农民那里获得了见解。我们使用描述性和推断性统计来分析数据。可可农民对社交媒体上的农业信息有一定程度的认识(总体平均值=1.88)。农民将社交媒体平台视为农业信息的潜在来源(感知指数=3.38)。大多数农民拥有智能手机(53.74%)并可以上网(53.74%)。约31.86%的农民每天花费30分钟至1小时的时间浏览社交媒体以获取农业信息。大约57.65%的人使用社交媒体访问农业信息和实施农业实践。根据89.38%的农民,社交媒体信息有助于提高作物产量和病虫害管理。农民在使用社交媒体时面临的主要制约因素是高数据成本(平均值=7.30)。我们建议政府与电信公司合作,探索创新的定价模式,以降低农民在线访问农业内容的成本障碍。
    In this study, we set out to investigate the transforming power of social media for agricultural extension delivery services in Ghana. We employed a quantitative research approach and drew insights from 374 farmers. We used descriptive and inferential statistics to analyse the data. Cocoa farmers have some level of awareness of agricultural information on social media (Overall Mean = 1.88). Farmers regard social media platforms as potential sources of agricultural information (Perception Index = 3.38). Majority of farmers own smartphones (53.74 %) and have internet access (53.74 %). About 31.86 % of farmers spend 30 min to 1 h daily time browsing social media for agricultural information. About 57.65 % use social media for accessing agricultural information and implementing farming practices. According to 89.38 % of farmers, social media information helps to improve crop yield and pest management. The main constraint facing farmers in the use of social media is high data costs (Mean = 7.30). We recommend that the government in collaboration with telecommunication companies should explore innovative pricing models to reduce the cost barrier for farmers accessing agricultural content online.

    AtriAmp是一种新的医疗设备,可使用临时心房起搏导线在遥测中显示连续的实时心房电描记图。我们的目标是评估在我们的儿科重症监护病房(PICU)内早期采用该设备的患者护理。这是一项定性研究,使用半结构化访谈的归纳分析来识别主导主题。这项研究是在单中心进行的,第三级,学术21床混合PICU。受试者是PICU多学科小组成员(儿科心脏重症监护,PICU护士从业人员,PICU护士和小儿心脏病学家)是AtriAmp的早期采用者(n=14)。出现了三个突出的主题:(1)从心律失常事件到诊断和治疗的时间加快;(2)提高提供者对心律失常诊断准确性的信心;(3)提高提供者对术后心律失常的教育能力。供应商还注意到了一些学习曲线,但没有损害医疗或临床工作流程。AtriAmp早期采用者的见解表明,新的PICU技术需要简单性和保真度。我们的研究表明,这些技术对于多学科团队的支持和发展至关重要。即使是那些不参与早期实施的人。需要进一步的研究来了解何时以及为什么在高风险环境中采用新技术变得普遍。
    AtriAmp is a new medical device that displays a continuous real-time atrial electrogram on telemetry using temporary atrial pacing leads. Our objective was to evaluate early adoption of this device into patient care within our pediatric intensive care unit (PICU). This is a qualitative study using inductive analysis of semi-structured interviews to identify dominant themes. The study was conducted in a single-center, tertiary, academic 21-bed mixed PICU. The subjects were PICU multidisciplinary team members (Pediatric Cardiac Intensivists, PICU Nurse Practitioners, PICU nurses and Pediatric Cardiologists) who were early adopters of the AtriAmp (n = 14). Three prominent themes emerged: (1) Accelerated time from arrhythmia event to diagnosis and treatment; (2) Increased confidence in the accuracy of providers\' arrhythmia diagnosis; and (3) Improvement in the ability to educate providers about post-operative arrhythmias. Providers also noted some learning curves, but none compromised medical care or clinical workflow. Insights from early adopters of AtriAmp signal the need for simplicity and fidelity in new PICU technologies. Our research suggests that such technologies can be pivotal to the support and growth of multi-disciplinary teams, even among those who do not participate in early implementation. Further research is needed to understand when and why novel technology adoption becomes widespread in high-stakes settings.

    这项研究调查了研究人员对开放获取(OA)出版的看法和因素,特别是它如何影响他们的决定发表或不发表。罗杰斯的创新扩散理论作为研究的主要指南,来自加纳科学与工业研究理事会作物研究所的15名研究科学家通过半结构化访谈和解释性研究范式为研究提供了定性数据。使用便利抽样来选择参与者,并采用主题分析法对研究结果进行主题分析和呈现。该研究的结论表明,所有参与者都从OA中受益,并且他们都知道OA在传播科学信息方面的应用。研究中还提到高额物品处理费用(APC)和信誉问题是使用OA传播科学信息的重大障碍。该研究表明,为了让科学家使用开放获取(OA)来共享科学信息,他们必须有办法区分可信赖的期刊和掠夺性的期刊。
    This study investigated the perceptions and factors that researchers had about Open Access (OA) publishing, specifically how it affected their decision to publish or not. The Diffusion of Innovation Theory by Rogers served as the study\'s main guide, and 15 research scientists from Ghana\'s Council of Scientific and Industrial Research\'s Crop Research Institute provided qualitative data for the study through semi-structured interviews and the interpretivist research paradigm. Convenience sampling was used to choose the participants, and thematic analysis was used to analyse and present the research results in themes. The study\'s conclusions showed that all of the participants benefited from OA and that they were all aware of its application for disseminating scientific information. High Article Processing Charges (APC) and credibility issues were also mentioned in the study as significant obstacles to using OA for the dissemination of scientific information. The study suggests that in order for scientists to use Open Access (OA) for the sharing of scientific information, they must be given the means to distinguish trustworthy journals from predatory ones.

    随着信息技术的飞速发展,远程医疗应用程序已逐渐成为为患者提供更方便的不可或缺的工具,高效,和可获得的医疗保健服务。然而,这些应用程序的成功实施在很大程度上取决于公众的广泛接受。为了彻底调查影响公众接受这些应用程序的因素以及这些因素之间的关系,本研究建立了基于创新扩散理论和感知价值理论的理论模型。要验证此模型,我们对北京387名居民进行了调查,中国,并采用结构方程模型对收集到的数据进行分析。研究结果表明,创新扩散的属性,包括相对优势,兼容性,复杂性,可试验性,和可观察性,对公众的感知价值有显著的正向影响。特别值得注意的是,感知价值部分中介了创新属性与公众接受度之间的关系,强调感知价值在公共决策过程中的关键作用。这项研究采用了理论驱动的方法来阐明远程医疗应用程序的接受程度,并为现有文献提供了新的见解。通过整合创新扩散和顾客感知价值的研究范式,我们对个体认知过程如何导致接受行为提供了连贯的解释。总之,这项研究丰富了现有的关于远程医疗应用程序接受的理论研究,并对医疗实践具有积极的意义。
    With the rapid advancement of information technology, telemedicine apps have gradually become an indispensable tool for providing patients with more convenient, efficient, and accessible healthcare services. However, the successful implementation of these apps largely depends on widespread acceptance among the public. To thoroughly investigate the factors influencing the public\'s acceptance of these apps and the relationships between these factors, this study developed a theoretical model based on the Diffusion of Innovation theory and the Theory of Perceived Value. To validate this model, we conducted a survey of 387 residents in Beijing, China, and employed structural equation modeling to analyze the collected data. The research findings indicate that attributes of innovation diffusion, including relative advantage, compatibility, complexity, trialability, and observability, significantly and positively influence the public\'s perceived value. Particularly noteworthy is that perceived value partially mediates the relationship between innovation attributes and public acceptance, emphasizing the crucial role of perceived value in the public decision-making process. This study employed a theory-driven approach to elucidate the acceptance of telemedicine apps and offers fresh insights into the existing literature. By integrating the research paradigms of innovation diffusion and customer perceived value, we provide a coherent explanation of how individual cognitive processes lead to acceptance behavior. In summary, this research enriches the existing theoretical studies on the acceptance of telemedicine apps and holds positive implications for healthcare practice.

    大量生产的农作物秸秆可以利用和增值,具有巨大的经济和环境效益。中国政府采取了农作物秸秆资源化利用试点政策(CSRU)来处理秸秆和实施废物增值。这项工作以中国河北省164个县为案例研究,绘制了该省CSRU试点政策扩散的时空特征,并通过建立二元logistic回归模型进行了事件历史分析,从资源可获得性方面找出决定CSRU试点政策在中国推广的具体因素,内部能力,和外部压力。这表明:(1)CSRU试点政策在河北省快速推广,尽管仍处于这种政策扩散的早期阶段;(2)该模型解释了采用试点县的95.2%的差异,表明该模型的有效性;(3)秸秆资源密度对CSRU试点选择有积极影响,它可以使一个县被选为CSRU试点的可能性增加23.2%,而人口密度表现出负效应;(3)地方政府的政策支持是决定CSRU绩效的主要内部因素,它可以增加一个县被选为CSRU试点的可能性近十倍;来自邻近县的接近压力对CSRU政策的扩散有积极影响,这也大大增加了被选为CSRU试点的可能性。
    Massively generated crop straw can be utilized and valorized with great economic and environmental benefits. The Chinese government has adopted the pilot policy of crop straw resource utilization (CSRU) for disposing of the straw and practicing waste valorization. This work took 164 counties in the Hebei Province of China as a case study, mapped the temporal and spatial characteristics of the diffusion of the CSRU pilot policy in this province, and conducted an Event History Analysis by establishing a binary logistic regression model to identify the specific factors that determine the diffusion of the CSRU pilot policy in China from the aspects of resource availability, internal capacity, and external pressure. It indicates that: (1) the CSRU pilot policy diffuses rapidly in Hebei Province, although it is still at the early stage of this policy diffusion; (2) the model explains 95.2% of the variance in adopting a pilot county, indicating the effectiveness of this model; (3) straw resource density has a positive impact on CSRU pilot selections, and it can increase the possibility of one county being selected as a CSRU pilot by 23.2%, while population density has shown a negative effect; (3) policy support from local government is a major internal factor that determines CSRU performance, and it can increase the possibility of one county being selected as a CSRU pilot nearly tenfold; proximity pressure from neighboring counties has a positive effect on the diffusion of the CSRU policy, and it also greatly increases the possibility of being selected as a CSRU pilot.

    本研究通过调查社会和个人因素与使用虚拟现实的行为意图之间的关系,为现有的教学技术文献做出了贡献。此外,当前的研究检查了虚拟现实的感知特征与态度之间的联系,以及这些联系之间的感知技能准备程度可以发挥的调节作用。受计划行为理论和创新扩散理论的启发,形成了一组假设,以使用结构方程建模偏最小二乘法对阿曼171名科学教师的样本进行测试所提出的关系。结果表明,态度,社会规范和感知行为控制可以预测使用虚拟现实的行为意图,其中态度是最强的预测因子。此外,结果表明,相对优势可以预测使用虚拟现实的态度,而兼容性和可观察性不能。最后,感知技能准备可以加强虚拟现实应用程序的感知特征之间的关系(相对优势,兼容性和可观察性)以及在科学课堂中使用虚拟现实的态度。因此,这项研究强调了关注科学教师使用虚拟现实的技能准备的重要性,这样他们就可以自信地使用它。讨论了意义和未来的研究。
    This study contributes to the extant literature on instructional technology by investigating the relationships between the social and personal factors and behavioral intention to use virtual reality. Moreover, the current study examined the links between perceived characteristics of virtual reality and attitude and the moderating role that can be played by perceived skills readiness between those links. Inspired by the Theory of Planned Behaviour and Diffusion of Innovation Theory, a set of hypotheses was formed to test the proposed relationships using structural equation modeling partial least square to a sample of 171 science teachers in Oman. The results showed that attitude, social norms and perceived behavioral control can predict behavioral Intention to use virtual reality with attitude as the strongest predictor. Furthermore, the results indicated that relative advantage could predict attitude towards using virtual reality while compatibility and observability cannot. Finally, perceived skills readiness can strengthen the relationship between the perceived characteristics of virtual reality applications (relative advantage, compatibility and observability) and attitude towards using the virtual reality in the science classroom. Thus, this study highlights the importance of focussing on science teachers\' skills readiness to use virtual reality so that they can use it confidently. Implications and future research studies are discussed.

    The COVID-19 pandemic has altered the way small and medium-sized businesses (SMEs) function. To maintain business efficiency and reduce operating costs in the context of the constraints imposed by the pandemic, SMEs have been forced to embrace new digital technologies. Cloud accounting is becoming an increasingly important business operating tool for SMEs. By adopting cloud-based accounting, SMEs can become more efficient, financially organized, and flexible. This study aims to investigate the factors that have a pervasive influence on cloud accounting adoption among SMEs in Thailand, following the pandemic\'s effects. This study integrates three technology adoption theories-the Technology-Organization-Environment framework, Diffusion of Innovation theory, and Institutional Theory-and studies them alongside SMEs\' unique characteristics. The research employs a qualitative case study method and triangulated sources of evidence. The findings provide important implications for the research community, policymakers, cloud accounting vendors, and SME owners aiming to formulate better approaches to cloud accounting adoption after the pandemic. The results suggest that vendors should focus on SMEs\' particular characteristics and needs. By contrast, SMEs should determine the organizational fit of the cloud accounting platform and integrate cloud accounting with other aspects of their operations.

    Background: Globally, diabetes has brought an enormous burden to public health resources, and the situation of disease burden caused by diabetes in China is especially severe. China is currently facing the dual threat of aging and diabetes, and wearable activity trackers could promote elderly diabetic patients\' physical activity levels and help them to manage blood glucose control. Therefore, examining the influencing factors of elderly patients\' adoption intention is critical as wearing adoption determines actual wearing behaviors. Objective: This study aims to explore the predicting factors of Chinese elderly type 2 diabetic patients\' adoption intention to wearable activity trackers and their actual wearing behavior, using diffusion of innovation theory as the theoretical framework. We hope to provide insights into future interventions using wearable activity trackers as tools to improve the outcome of patients. Methods: Wearable activity trackers were freely distributed to type 2 diabetic patients in Beijing, China. A questionnaire survey was conducted to examine predicting factors of adoption intention after a week\'s try-on. Actual wearing behavior for 3-month was obtained from the exclusive cloud. Data were analyzed with structural equation modeling. Results: A total of 725 patients completed the questionnaire. Patients had a mean age of 60.3 ± 7.6 years old and the educational level was generally lower. The results indicated that observability was the primary influencing factor of patients\' adoption intention (β = 0.775, P < 0.001). Relative advantage (β = 0.182, P = 0.014) and perceived social image (β = 0.080, P = 0.039) also had a positive influence while perceived risk (β = -0.148, P < 0.001) exerted a negative influence. In addition, results showed that the more intention led to the better actual wearing behavior (β = 0.127, P = 0.003). Observability (β = 0.103, P = 0.005), perceived ease (β = 0.085, P = 0.004), and relative advantage (β = 0.041, P = 0.009) also indirectly influenced the wearing behavior. Conclusion: The intentions of Chinese elderly type 2 diabetic patients to wearable activity trackers directly influenced the actual wearing behavior. In addition, their adoption intention to wearable activity trackers was mainly influenced by observability, perceived ease to use, relative advantage, perceived risk, and social image.
