In 2019, two court rulings in China on the issue of copyrightability of AI creations received international attention. It was reported that in Feilin v. Baidu, known as the first AI case, the Beijing Internet Court denied copyright of AI creations, whereas the Shenzhen Nanshan District People’s Court acknowledged copyright of AI creations in the Tencent Dreamwriter case. The two cases, however, were quite similar, as they acknowledged copyright of AIassisted, not AI-generated, written works and recognized these works as a work of a legal entity. The difference between the two judgments is that the Beijing Internet Court regarded originality as an independent requirement and judged it according to the objective standard, whereas the Shenzhen Nanshan District People’s Court regarded human creation as part of the requirement of originality. In this sense, it was the Beijing Internet Court that actually made the more favorable judgment on an AI-generated work.

Hispidin is a secondary metabolite found in numerous medicinal mushrooms that has attracted significant attention, owing to its distinct biological effects, including antioxidant, anti-inflammatory, antitumor, and cytoprotective properties. Experiments are being carried out to study the interaction of detonation nanodiamonds (DNDs) with synthetic and natural hispidin sourced from extracts of Pholiota sp. fungus. The bioluminescence method is used to determine the adsorption/ desorption properties of DNDs toward hispidin. It is found that hispidin forms strong conjugates with DNDs, and the use of various eluents does not result in a significant release of the adsorbed hispidin molecules. DND-bovine serum albumin (BSA) complex, where DNDs serve as a carrier for the protein and the latter acts as a hispidin sorbent, has been developed and applied in hispidin adsorption/desorption tests. The results support the use of the DNDs as a carrier for hispidin in medical applications. They also advocate the application of the DND-BSA complex for isolating the substance from fungal extracts.

The Indonesian Ocean Policy (IOP) is a new milestone in managing its oceans since Indonesia ratified the UNCLOS 35 years ago. Indonesia underwent several paradigm shifts in strengthening ocean governance from 1957 to 2014. This research aims to analyse three paradigm shifts in strengthening ocean governance in Indonesia. The research revealed that the milestone of the first shift was the 1957 Djuanda Declaration, recognised by the UNCLOS in 1982, regarding the concept of an archipelago state, called the ‘ocean space paradigm.’ The second, which occurred in the Reformation period (1998-2014) was called the Ocean Development paradigm, while the third paradigm shift was after President Jokowi launched Indonesia’s vision as a Global Maritime Fulcrum. This third paradigm shift was also associated with the emergence of the IOP, which contributes to national development and pays comprehensive attention to the constellation of relations between the countries in Asia and various initiatives in the region.

The social media influencer (SMI) phenomenon is attracting attention from academia and business. A SMI refers to an individual who has accumulated a sizable social network of followers and thereby has influence over others (Ki et al., 2020). Due to the influence SMIs possess, an increasing number of brands are approaching SMIs and asking them to create and share branded content that includes product placements or brand recommendations. This practice is commonly referred to as influencer marketing. Reflecting the trend of influencer marketing, this study investigated: (1) whether consumers are ‘inspired-by’ SMIs and ‘inspired-to’ adopt the exemplars of SMIs (e.g., SMIs’ lifestyles, styles, and recommendations) as their social defaults that provide desirable standards that consumers will like and follow, and if so, (2) what are its causal factors and effects, and (3) whether the inspiration mechanism between SMIs and consumers differs between male and female consumers. In so doing, we drew on social defaults theory (Huh et al., 2014) and customer inspiration theory (Böttger et al., 2017).

This study investigates the association between Food Neophobia and the intention of the consumers to buy fish farmed with insect-based flours. The findings suggest that buying intention is strongly influenced by the attitude of consumers toward this type of fish and both Food Neophobia and Food Technology Neophobia negatively influence consumers’ attitude.

The two key variables of an Si solar cell, i.e., emitter (n-type window layer) and base (p-type substrate) doping levels or concentrations, are studied using Medici, a 2-dimensional semiconductor device simulation tool. The substrate is ptype and 150 μm thick, the pn junction is 2 μm from the front surface, and the cell is lit on the front surface. The doping concentration ranges from 1 × 1010 cm−3 to 1 × 1020 cm−3 for both emitter and base, resulting in a matrix of 11 by 11 or a total of 121 data points. With respect to increasing donor concentration (Nd) in the emitter, the open-circuit voltage (Voc) is little affected throughout, and the short-circuit current (Isc) is affected only at a very high levels of Nd, exceeding 1 × 1019 cm−3, dropping abruptly by about 12%, i.e., from Isc = 6.05 × 10−9 A·μm−1, at Nd = 1 × 1019 cm−3 to Isc = 5.35 × 10−9 A·μm−1 at Nd = 1 × 1020 cm−3, likely due to minority-carrier, or hole, recombination at the very high doping level. With respect to increasing acceptor concentration (Na) in the base, Isc is little affected throughout, but Voc increases steadily, i.e, from Voc = 0.29 V at Na = 1 × 1012 cm−3 to 0.69 V at Na = 1 × 1018 cm−3. On average, with an order increase in Na, Voc increases by about 0.07 V, likely due to narrowing of the depletion layer and lowering of the carrier recombination at the pn junction. At the maximum output power (Pmax), a peak value of 3.25 × 10−2 W· cm−2 or 32.5 mW· cm−2 is observed at the doping combination of Nd = 1 × 1019 cm−3, a level at which Si is degenerate (being metal-like), and Na = 1 × 1017 cm−3, and minimum values of near zero are observed at very low levels of Nd ≤ 1 × 1013 cm−3. This wide variation in Pmax, even within a given kind of solar cell, indicates that selecting an optimal combination of donor and acceptor doping concentrations is likely most important in solar cell engineering.

The various sintered samples comprising of 72 wt%(Al2O3) : 28 wt%(SiO2) based ceramics were fabricated using a colloidal processing route. The phase analysis of the ceramics was performed using an X-ray diffractometer (XRD) at room temperature confirming the presence of Al2O5Si and Al5.33Si0.67O9.33. The surface morphology of the fracture surface of the different sintered samples having different sizes of grain distribution. The resistive and capacitive properties of the three different sintered samples at frequency sweep (1 kHz to 1 MHz). The contribution of grain and the non-Debye relaxation process is seen for various sintered samples in the Nyquist plot. The ferroelectric loop of the various sintered sample shows a slim shape giving rise to low remnant polarization. The excitation performance of the sample at a constant electric signal has been examined utilizing a designed electrical circuit. The above result suggests that the prepared lead-free ceramic can act as a base for designing of dielectric capacitors or resonators.
