The Zhuanglang River is a primary tributary of the Yellow River. Tracing back to the prehistoric period, the numerous scattered settlement sites within the basin indicate that early inhabitants settled and flourished here, creating a unique and splendid culture. The Gejiawan site differs from other nearby Neolithic sites in that it is characterized by the widespread use of stone tools and a relatively high proportion of knapped (flaked) implements, a distinctive feature. We tentatively propose that the Gejiawan site may have served as a regional center of the Machang-type Neolithic in this area. Compared with contemporaneous surrounding sites, the Gejiawan site occupies a more open location with a wider visual field and covers a larger area; the artifacts recovered from the site are abundant in quantity, diverse in type, and finely worked, and craft technologies appear well developed. These attributes fully demonstrate the composite characteristics of the Machang culture’s subsistence strategies.

Authenticity refers to the distinctive individuality that differentiates a person from others, emphasizing uniqueness and sincerity of the self. In the era of rapidly evolving social media, authenticity has become a core value in self-expression and identity construction, yet it also faces unprecedented challenges and reconceptualization. On one hand, users strive to present an authentic self on social platforms in pursuit of recognition and emotional resonance. On the other hand, algorithmic curation, content recommendation mechanisms, and platform-specific interaction rules constantly shape and intervene in users' expressive behaviors, blurring the boundary between the authentic and the performative. This paper examines the authenticity dilemma through case studies and a literature review, focusing on how technological mediation, capital logic, and social dynamics collectively challenge the notion of authenticity. Beginning with a conceptual deconstruction of authenticity, the study further explores the problems and manifestations of authenticity in contemporary social media environments.

With breakthroughs in neural interfaces and holographic interaction technologies, the metaverse is evolving from a science fiction concept into a revolutionary domain that redefines human existence. This paper, grounded in Jean-Paul Sartre's existentialist philosophy, mainly focuses on the virtual-physical symbiotic metaverse at its technological maturity stage, reveals the limits of freedom and the dilemmas of responsibility within the new dimensions of digital existence. By systematically examining the validity of the three principles of existentialism (existence precedes essence, man is the sum of his actions, and freedom is responsibility) in the context of the metaverse, the study finds that while sensory simulation and digital avatars break free from physical constraints, they fall into new forms of alienation characterized by the boundaries of imagination, algorithmic manipulation, and fragmented identity. The “irresponsible revelry” in single-player mode is actually an escape from ontological responsibility, and its behavioral patterns will eventually backfire on real-world personalities; the illusion of digital immortality fundamentally undermines the authentic value of “living toward death.” It proposes an “existential scheme for virtual-physical symbiosis,” emphasizing that individuals must adhere to three principles within the technological framework: establishing the uniqueness of the conscious subject, acknowledging the constitutive responsibility of virtual actions, and resisting algorithmic alienation through active choice. This study provides an existentialist philosophical framework for examining metaverse ethics, revealing the crisis of subjectivity underlying the utopian façade of technology, and offers cautionary value for building a responsible digital civilization.

This research delves into the effects of social interaction and motivational factors on exercise routines, focusing specifically on runners within urban spaces like Centennial Park Sydney. It endeavors to bolster public health by scrutinizing the effects of integrating design elements into urban environments, with the aim of fostering greater social interaction among runners. The study will initiate with ethnographic observation of runners followed by the implementation of cultural probes and a series of small-scale design intervention prototypes within areas of Centennial Park placed randomly. These design interventions will encompass visual markers integrated into the routes, along with social seating and interactive art pieces integrated with the aim of compelling the runners to engage in social interactions. According to the research, when runners exercise with companions, they tend to be more committed to their training plans due to mutual encouragement and support. Additionally, engaging in conversations during the run can create a more positive and enjoyable experience, helping runners to forget about fatigue and discomfort, ultimately improving their performance.
