基于活态遗产保护的田园综合体生态构建 路径——以云南景迈山古茶林文化景观申遗示 范区为例

田园综合体作为国家推动农业农村现代化的重要抓手,近年来在各省市的试点建设取得了初步成效,主要以文旅、产业驱动的经济发展为导向,缺失了对乡村地区既有遗产要素的关注。尤其对于具备一定景观资源禀赋的村镇,在构建田园综合体的过程中必然面临着保护和发展之间的困境。从ICCROM界定的活态遗产概念切入,探讨了乡村地区活态遗产“无形-社群-象征-实体”的类型要素和价值认知框架,在比较了国内外乡村遗产的3种保护模式的基础上,提出田园综合体发展和乡村活态遗产保护的共融路径。以云南省澜沧景迈山田园综合体作为案例实证,围绕着申报世界文化遗产的古茶林文化景观,深入解读、挖掘景迈山乡村遗产的多元价值群落,通过原生文化景观一体,源流汇生态空间修复;一二三产业融合,聚落单元联动发展;民众参与共建,经济效益共享三项涉及自然和人文景观的延续性发展策略,以期为中国田园综合体生态建设和世界乡村遗产保护做出探索性实践。

Situation-centered goal reinforcement of activities of daily living in smart home environments

Older adults with early-stage dementia (ED) can experience confusion or lack clarity when performing routine activities of daily living (ADLs). These circumstances predispose the older adult to safety-critical and often risky situations. A safety-critical risky situation is one that constitutes a hazard. To support independent living, a sensor-laden smart environment can be employed to mitigate such hazards. In this paper, we propose a situation-centered goal reinforcement framework that supports older adults with ED in their decision making, and guides them through their ADL in order to fulfill their goal or intention and avoid hazards. First, we employ an LSTM (Long Short-Term Memory) model to infer the current goal of the resident, using their previously observed normal ADL patterns. Secondly, we identify potentially risky situations in their currently observed goal path. We then incorporate a situ-learning agent (SLA) that helps an inhabitant to make the right decision, thus preventing adverse events while guiding her through the task sequence that leads to her goal state. In addition, we use a naïve agent to simulate episodes of confusion similar to those that might be experienced by older adults with ED. We validated our method against an open-source dementia dataset (Quesada et al., 2015) by considering four types of ADLs as case studies. We achieved an accuracy of 90.1% for our goal inference model, higher than the accuracies reported by related studies. We also reported other metrics including precision, recall and f1-score for goal inference model. Finally, SLA's action recommendations relevance was evaluated accordingly.     

Blocking a chemical communication between Trichoplax organisms leads to their disorderly movement

ABSTRACT

We described an ‘expansion’ phenomenon of the Trichoplax sp. H2. The animals were transferred from algal mats to a Petri dish without food with the subsequent passage into the similar Petri dish. The animals’ motion and receding into the distance at the new place was modelled by the increasing spacing between individuals/objects. A collective behaviour of trichoplaxes was disrupted by the addition of 0.01% Bovine Serum Albumin (BSA), which assumedly blocked an interaction of signalling molecules with receptors. BSA-treated trichoplaxes demonstrated the stochastic motion that is in a good agreement with the model of independent random particles.     

Polymerization of Substituted Acetylenes Using Well‐Defined Rhodium Complex Catalyst. Chirality Transfer and Amplification in Chiral‐Chiral Block and Random Copolymers

Block and random copolymers are synthesized by the copolymerization of N‐tert‐butoxycarbonyl‐?‐valine 4‐ethynylanilide ( 1L ) and N‐tert‐butoxycarbonyl‐d‐valine 4‐ethynylanilide ( 1D ) using [(nbd)Rh{C(Ph) = CPh₂}(PPh₃)]/PPh₃ as a catalyst. The size exclusion chromatography (SEC) peaks show narrow polydispersities from the first stage polymerization to the second one in the block copolymerization. Poly( 1L ₂₅‐ran‐ 1D ₂₅) exhibits no circular dichroism (CD) signal, while poly( 1L ₂₅)‐block‐poly( 1D ₂₅) exhibits weak CD signals with the same sign as those of poly( 1L ₅₀), suggesting the occurrence of chirality transfer from the poly( 1L ) block to poly( 1D) block. The relationship between the |g| values and 1L / 1D contents of the block copolymers becomes almost linear at the region of each unit larger than 60%. On the other hand, the relationship between these two factors of the random copolymers is convex upward.     

Cyber-Physical-Social System Between a Humanoid Robot and a Virtual Human Through a Shared Platform for Adaptive Agent Ecology

Two artificial agents (a humanoid robot and a virtual human) are enriched with various similar intelligence, autonomy, functionalities and interaction modalities. The agents are integrated in the form of a cyber-physical-social system (CPSS) through a shared communication platform to create a social ecology. In the ecology, the agents collaborate (assist each other) to perform a real-world task (search for a hidden object) for the benefits of humans. A robot-virtual human bilateral trust model is derived and a real-time trust measurement method is developed. The role of taking initiative in the collaboration is switched between the agents following a finite state machine model triggered by bilateral trust, which results in a mixedinitiative collaboration. A scheme is developed to evaluate the performance of the agents in the ecology through the CPSS. The results show that the robot and the virtual human perform satisfactorily in the collaboration through the CPSS. The results thus prove the effectiveness of the real-world ecology between artificial agents of heterogeneous realities through a shared platform based on trust-triggered mixed-initiatives. The results can help develop adaptive social ecology comprising intelligent agents of heterogeneous realities to assist humans in various tasks through collaboration between the agents in the form of a CPSS.
