The purpose of this review paper is to create a piece of one-stop communication about important land zoning and land use, permits and tax guidelines for farmers venturing into agritourism in the Commonwealth of Virginia, USA. It also examines and complements prior studies on the distribution of agritourism in Virginia. A systematic literature review is conducted. Foundational legal prerequisites for agritourism and other emerging factors for the distribution of agritourism in Virginia are identified. Farmers must invest in what they are legally expected of and also learn how best to protect themselves and their business from law infringement before and during agritourism operations. Additionally, the complementary findings of the factors of agritourism distribution can guide farmers strategically in Virginia. This review paper contributes to agritourism literature and demonstrates the relevance of safety and protection against avoidable liability. This article provides excellent grounds to begin conversations with specialists such as attorneys, tax analysts, and insurance companies who can help Virginia farmers assess risk and put their businesses on the best track.

Analysis of Factors that Predict Positive Emotion and Well-Being Using Continuous Tracking 预测积极情绪和幸福感因素的持续追踪分析
Pub Date : 2023-03-18 DOI: 10.51390/vajbts.v1i3.28

The main objective of this work is to use quantified emotions and continuous evaluation to determine significant factors in predicting an individual’s overall well-being. In 2011, Martin Seligman introduced the concept of “PERMA” of factors that account for measuring an individual’s well-being. The PERMA theory separates overall well-being into five pillars of Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment. Seligman’s work has led to the development of many questionnaires and scales incorporating this theory and has since become an industry standard for positive psychology. However, the origins of “PERMA” remain mostly unclear and little work has explored supporting these concepts with continuous tracking measures. The work in this present study was carried out by utilizing positive emotion and well-being tracking over a span of six-months, where positive emotion was evaluated in fifteen-minute intervals and well-being was evaluated daily. Additionally, a questionnaire was developed and prompted to the participant, and the tracked measures are evaluated as predictors for positive emotion and well-being. Many findings for well-being align closely with the theories in PERMA, with strong associations with accomplishment and relationships. Predictive factors that align with the participant’s well-being not included in PERMA include the influence of anticipation and specific physical and dietary components. Factors that influence positive emotion and daily exhaustion are analyzed and discussed as well. Distribution analysis of positive emotion emphasizes the impact of momentary, extremely happy moments for well-being. Future work should provide direction for studies to evaluate these findings and a new iteration of tracking measures.
这项工作的主要目的是使用量化的情绪和持续的评估来确定预测个人整体幸福感的重要因素。2011年,马丁·塞利格曼(Martin Seligman)引入了衡量个人幸福感的因素“PERMA”概念。PERMA理论将整体幸福感分为五大支柱:积极情绪、参与、关系、意义和成就。塞利格曼的工作导致了许多纳入这一理论的问卷和量表的发展,并从此成为积极心理学的行业标准。然而,“PERMA”的起源仍然不清楚,并且很少有研究通过持续跟踪措施来支持这些概念。在本研究中,研究人员利用积极情绪和幸福感跟踪进行了为期六个月的研究,每隔15分钟评估一次积极情绪,每天评估一次幸福感。此外,研究人员还开发了一份问卷,并向参与者发出了提示,跟踪的测量结果被评估为积极情绪和幸福感的预测因素。许多关于幸福的发现与PERMA的理论密切相关,与成就和人际关系密切相关。与参与者的健康相一致的预测因素不包括在PERMA中,包括预期和特定的身体和饮食成分的影响。并对影响积极情绪和日常疲惫的因素进行了分析和讨论。积极情绪的分布分析强调了瞬间的影响,非常快乐的时刻对幸福感的影响。未来的工作应该为研究提供方向,以评估这些发现和跟踪措施的新迭代。

Diverse Revolutions brought about by Designing Architecture in Virtual Reality 虚拟现实中的建筑设计带来的多种革命
Pub Date : 2023-03-18 DOI: 10.51390/vajbts.v1i6.30

Architecture is facing a singularity; the focal point of the singularity is virtual reality, virtual twins of architecture, and virtual public space, a central principle is the (so far inaccessible) authentic diachronic perception of architecture and its instantaneous creation from spaces within space. Architecture should embrace the singularity and undergo a reinvention of the discipline and the profession to rid itself of accumulated problems that often escape attention and whose essence is hidden. The prospect is to transform the paradigm of architectural design and built environment development planning, understanding architectural designs and communication with them, about them, and between interested professionals and the public. The benefits are to be numerous qualitative and quantitative increases in the performance of the profession and widespread and diverse improvements in the conditions and societal and sustainability profile of the built environment and architecture as a discipline. Based on a review of the state of the art of the field of software for architectural and building design, the paper reports on the research and development of a new software tool and virtual reality environment - Wearrecho - which fulfills the intended transformation and becomes its platform that links the virtual reality environment and parametric BIM software. The prevailing positive results of the experimental validation of their performance are presented, followed by a plan for continued research and development.
建筑正面临一个奇点;奇点的焦点是虚拟现实,建筑的虚拟双胞胎和虚拟公共空间,一个中心原则是(迄今为止无法实现的)对建筑的真实历时性感知及其在空间内空间的瞬时创作。建筑应该拥抱独特性,并经历对学科和专业的重新发明,以摆脱积累的问题,这些问题经常被忽视,其本质被隐藏。其前景是改变建筑设计和建筑环境发展规划的范式,理解建筑设计并与他们交流,关于他们,以及感兴趣的专业人士和公众之间的交流。其好处是在专业性能和广泛和多样化的条件和社会和可持续性的建设环境和建筑作为一门学科的发展方面的大量定性和定量的提高。基于对建筑和建筑设计软件领域最新技术的回顾,本文报告了一种新的软件工具和虚拟现实环境的研究和开发- Wearrecho -它实现了预期的转变,并成为连接虚拟现实环境和参数化BIM软件的平台。提出了实验验证其性能的普遍积极结果,并提出了继续研究和开发的计划。

 Phosphate is a protein vital for all organismal bodies and is a resource bacteria compete for. Bakers yeast activity under several concentrations of phosphate and an alkaline solution was observed through absorbance spectroscopy as a means of measuring the various levels of inhibition from several varying concentrations. This was expected to show increased bacterial activity to increased phosphate concentration. Under higher concentrations of phosphate, Saccharomyces Cerevisiae became inhibited. This study focused on determining if the activity of the yeast changes based on the varying concentrations of phosphate solutions.
磷酸盐是一种对所有生物体都至关重要的蛋白质,也是细菌竞争的资源。通过吸收光谱法观察了不同浓度的磷酸盐和碱性溶液下的酵母活性,以此作为测量不同浓度的抑制水平的一种手段。这表明细菌活性随着磷酸盐浓度的增加而增加。在较高的磷酸盐浓度下,酿酒酵母受到抑制。这项研究的重点是确定酵母的活性是否会随着磷酸盐溶液浓度的变化而变化。

Robotic Hand Wirelessly Controlled by User Worn Glove 由用户佩戴的手套无线控制的机械手
Pub Date : 2022-09-07 DOI: 10.51390/vajbts.v1i2.23

A robotic hand was designed to be remotely controlled by a user worn a glove. The glove used flex sensors to detect the position of the user’s fingers and then sent those positions to the corresponding fingers of the robotic hand via microcontrollers. The microcontrollers regulated the servo motors in order to move the robotic hand into a position mimicking the user. The robotic hand was modeled after the human hand but with only one degree of freedom for each finger, meaning the finger will only move from fully extended to fully curled without movement in any other directions. A wrist was attached to the robotic hand and it also moved with one degree of freedom. The robotic hand was completely 3-D printed out of ABS plastic and a tendon-servo system was used to flex the fingers. Elastic cord was used to extend the fingers back into the outstretched position when the servos relaxed the tendons. Several joint types for the hand were modeled and tested including ball and socket joints and revolute joints. Haptic feedback was included in the design by adding vibrational motors to the glove, and pressure sensors to the robotic hand, allowing hand-to-glove feedback. The hand was designed to be able to hold items ranging from the size of a golf ball to a tennis ball, including irregularly shaped objects within the range commonly held by human hands.
用户戴上手套,就可以远程控制机器人手。该手套使用弯曲传感器来检测用户手指的位置,然后通过微控制器将这些位置发送给机器人手的相应手指。微控制器调节伺服电机,以便将机械手移动到模仿用户的位置。机器人手是模仿人手的,但每个手指只有一个自由度,这意味着手指只能从完全伸展到完全卷曲,而不能向任何其他方向移动。一个手腕被连接到机械手上,它也以一个自由度移动。这只机械手完全是用ABS塑料3d打印出来的,并使用了一个肌腱伺服系统来弯曲手指。当伺服器放松肌腱时,使用弹性绳将手指伸回伸出的位置。几种关节类型的手建模和测试,包括球和窝关节和旋转关节。在设计中加入了触觉反馈,在手套上增加了振动马达,在机械手上增加了压力传感器,从而实现了手对手套的反馈。这只手被设计成能够握住从高尔夫球到网球大小的物品,包括人类手通常可以握住的不规则形状的物体。

Applying Predictive Modeling to Enhancing Solar Energy 应用预测模型增强太阳能
Pub Date : 2022-09-07 DOI: 10.51390/vajbts.v1i2.15
Victor Mukora
Though analysis has been provided on how factors like temperature or humidity impact panel efficiency, there has not been as much research conducted on how the various environmental conditions all relate with each other to affect solar energy output real-time. Having a model that correlates several environmental predictor variables known to impact solar energy can help determine what adjustments need to be made to optimize solar panel performance. In this project, prediction models like artificial neural networks (ANN), multiple linear regression (MLR), elastic, ridge, and lasso were used for relating environmental variables like high temperature, outside humidity, or rain rate to the total solar energy output produced. Data containing thirty-three different weather measurements and their respective solar energy outputs was obtained from the UK Power Networks and will be used as the principal dataset for the models. To check linear model assumptions like normality of residuals or heteroscedasticity for models like MLR, several functions provided from a model performance package in R verified whether the assumptions for the model were met. Predictive model selection was based on cross validation with k = 10 and Mean Squared Error (MSE). Neural networks were the highest performing model, but lasso and elastic net were the most interpretable models in terms of how conditions affected energy output.
虽然对温度或湿度等因素如何影响面板效率进行了分析,但对各种环境条件如何相互关联以实时影响太阳能输出的研究并不多。拥有一个将影响太阳能的几个已知环境预测变量关联起来的模型,可以帮助确定需要做出哪些调整来优化太阳能电池板的性能。在这个项目中,预测模型如人工神经网络(ANN)、多元线性回归(MLR)、弹性、脊和套索被用于将高温、室外湿度或降雨率等环境变量与产生的总太阳能输出联系起来。数据包含33种不同的天气测量和它们各自的太阳能输出是从英国电网获得的,并将用作模型的主要数据集。为了检验MLR等模型的残差正态性或异方差等线性模型假设,R中的模型性能包提供了几个函数来验证模型的假设是否满足。预测模型选择基于k = 10和均方误差(MSE)的交叉验证。神经网络是表现最好的模型,但套索和弹性网络是在条件如何影响能量输出方面最可解释的模型。

Facemask Wearing and Social Distancing: A Test of Risk Compensation Theory 戴口罩与社交距离:风险补偿理论的检验
Pub Date : 2021-07-07 DOI: 10.51390/VAJBTS.V1I1.17
Myriam Oliver
Studies suggest facemask wearing and social distancing are convenient ways to prevent the spread of the coronavirus. However, people might feel an unwarranted sense of safety when engaging in these COVID-prevention behaviors, as predicted by risk compensation theory. Our field research evaluated whether risk compensation influences facemask wearing and social distancing. The evidence-based theory of risk homeostasis presumes individuals will take more risks when they feel more protected. Therefore, someone wearing a facemask should feel safer and subsequently stand closer to others. Research students tested this theory by observing facemask wearing and social distancing in various locations. These students recorded three different observations in a Qualtrics survey: 1) an individual’s gender, 2) mask-wearing behavior (wearing a facemask, wearing a facemask incorrectly, or not wearing a facemask), and 3) the estimated distance between the individual and the nearest person within a six-foot radius. Our field observations of 2,068 individuals revealed that people wearing a facemask maintained greater social/interpersonal distances than did people not wearing a facemask or wearing a facemask incorrectly. This finding supports response generalization or a positive spillover effect rather than risk compensation.
研究表明,戴口罩和保持社交距离是防止冠状病毒传播的方便方法。然而,正如风险补偿理论所预测的那样,人们在从事这些预防新冠病毒的行为时可能会感到一种毫无根据的安全感。我们的实地研究评估了风险补偿是否会影响口罩佩戴和社交距离。基于证据的风险稳态理论认为,当个体感到受到更多保护时,他们会冒更多的风险。因此,戴口罩的人应该感到更安全,然后站得更近一些。研究学生通过观察不同地点的口罩佩戴和社交距离来验证这一理论。这些学生在Qualtrics调查中记录了三个不同的观察结果:1)个人的性别,2)戴口罩的行为(戴口罩,不正确戴口罩,或不戴口罩),以及3)该个人与6英尺半径内最近的人之间的估计距离。我们对2068人的现场观察显示,戴口罩的人比不戴口罩或不正确戴口罩的人保持更大的社会/人际距离。这一发现支持反应泛化或积极溢出效应,而不是风险补偿。

Universities in five different states are collaborating on an original large-scale COVID-prevention effort by asking many of their students to complete an innovative survey that strategically asks them to identify areas on and around campus that are “hot spots” for spreading the coronavirus. These universities—Virginia Tech, Appalachian State, Western Michigan, University of Kansas, and University of Florida—are also observing mask wearing, social distancing, and other COVID prevention measures in their communities to analyze the risk management and wellness precautions taken by students, faculty, and the surrounding communities. Mapping hot-spot areas provides invaluable information for prevention and intervention creation.
五个不同州的大学正在合作开展一项原创的大规模covid - 19预防工作,要求他们的许多学生完成一项创新调查,该调查战略性地要求他们确定校园内外的“热点”地区是冠状病毒传播的“热点”。这些大学——弗吉尼亚理工大学、阿巴拉契亚州立大学、西密歇根大学、堪萨斯大学和佛罗里达大学——也在各自社区观察佩戴口罩、保持社交距离和其他预防措施,以分析学生、教师和周边社区采取的风险管理和健康预防措施。绘制热点地区地图为制定预防和干预措施提供了宝贵的信息。

Nanomedicine is a rapidly advancing field as capabilities in nanoscale materials, devices, and sensing grow. Biocompatible nanoparticles have made their way into the pharmaceutical and biomedical market in imaging, diagnosis, targeted drug delivery, and even repair. Similarly, protein therapeutics show promise for their unique combination of high biospecificity and diverse function. This brief perspective explores the merging of these two fields via light-controlled methods mediated by photon-upconverting nanoparticles. The framework of three photoactive protein therapeutic systems will be explored for their integration with upconverting nanoparticles.
随着纳米材料、纳米器件和纳米传感技术的发展,纳米医学是一个快速发展的领域。生物相容性纳米颗粒已经进入制药和生物医学市场,用于成像、诊断、靶向药物输送,甚至是修复。同样,蛋白质疗法因其独特的高生物特异性和多种功能的结合而显示出希望。这个简短的观点探讨了通过光子上转换纳米粒子介导的光控方法合并这两个领域。三种光活性蛋白治疗系统的框架将探讨其与上转化纳米颗粒的整合。
