Reasoning Talk at Chinese Families’ Dinner Table: Across Three Generations and Different Communicative Contexts

This study examines the feature of reasoning talk used by 37 Chinese families at the dinner table across three generations with the background of co-parenting and in consideration of different communicative contexts. Drawing upon Hasan’s semantic framework, reasons were mainly coded as logical or social types. We categorize the communicative context of reasoning talk into contextualized (meal-related) and decontextualized topics. When the proportion of social reasoning was found slightly higher than that of logical reasoning, the families’ reasoning talk account for only 3.85% of the total language. Specifically, the count of mothers’ total reasoning talk was significantly above other family members, while there were no significant differences among the other participants. The effect of the communicative contexts on family members’ social reasoning was found. The reasoning talk grounded on local rules (family-made rules) and coercive power occurred significantly more frequently in contextualized than decontextualized context. A higher rate of local-rule grounded reasoning talk of all family members appeared in contextualized than decontextualized context, and this gap was particularly obvious among mothers. These findings reveal the significant role of mothers in family communications and confirm the pedagogical values of decontextualized communicative context for promoting children’s learning opportunities at the dinner table.

Local rule-making as an element of local legal order

The article analyzes the problematic issues of the content of local rule-making activity, which is considered as an element of the local legal order. It is noted that local rule-making should be necessary, not accidental. Local regulations acts are correlated with corporate acts. It is proposed to consider them as independent but partially overlapping phenomena. The segment of their intersection depends on the direction of legal regulation, methods of objectification outside and the type of the subject that generates them. The tendency of decentralization of legal regulation and its influence on the local legal order is noted. Local legal regulation has a limited scope of regulation (within a collective formation), is subordinate in nature, implements a generally permissible approach in a strictly defined legal framework and forms a local legal order

EXISTENCE OF BALI PIG THROUGH THE USABA SUMBU IN DESA ADAT TIMBRAH, KARANGASEM DISTRICT

Pigs are one of the most important in Balinese society, especially those who are Hindus because pig farm animals are the main component that is always present in every ritual activity in Bali. This gap can also be used to maintain the existence of bali pigs which are currently not counted. Karangasem is one of the clearest areas to become a pilot project to maintain the existence of bali pigs. Karangasem has two very large traditions that spearhead the establis- hment of the existence of the bali pig, namely Usaba Dalem and Usaba Sumbu. Two ritual processions above said the number of pork rolls in these two locations is already very large, and is one to be the starting point the program develops the preservation of bali pigs. So far the pigs used by people in both locations mostly use race pigs. If there is a choice in pigs, then there will be a huge opportunity for bali pigs. This is also a challenge for bali pig farmers to increase the amount of production through a more intensive system. Most people want to use bali pork as raw material for guling pork, if it is available, even some community leaders to use pork for perararem (local rule) are used, if the bali pig population is sufficient.

An additive algorithm for origami design

Inspired by the allure of additive fabrication, we pose the problem of origami design from a different perspective: How can we grow a folded surface in three dimensions from a seed so that it is guaranteed to be isometric to the plane? We solve this problem in two steps: by first identifying the geometric conditions for the compatible completion of two separate folds into a single developable fourfold vertex, and then showing how this foundation allows us to grow a geometrically compatible front at the boundary of a given folded seed. This yields a complete marching, or additive, algorithm for the inverse design of the complete space of developable quad origami patterns that can be folded from flat sheets. We illustrate the flexibility of our approach by growing ordered, disordered, straight, and curved-folded origami and fitting surfaces of given curvature with folded approximants. Overall, our simple shift in perspective from a global search to a local rule has the potential to transform origami-based metastructure design.

Mining stochastic cellular automata to solve density classification task in two dimensions

Density Classification Task (DCT) is a well-known problem that researchers have been tackling for more than two decades, where the main goal is to build a cellular automaton whose local rule gives rise to emergent global coordination. We describe the methods used to identify new cellular automata that solve this problem. The design of our cellular automata was carried out by a parallel genetic algorithm, specifically instantiated for this task. Our approach identifies both the neighborhood and its stochastic rule using a dataset of initial configurations that covers in a predefined and balanced way the full range of densities in DCT. We compare our results with some models currently available in the field. In some cases, our models show better performance than the best solution reported in the literature, with efficacy of 0.842 for datasets with uniform distribution around the critical density. The best-known cellular automaton achieves 0.832 in the same datasets. Tests are carried out in datasets of diverse lattice sizes and sampling conditions; we focused the analysis on the performance of our model around critical densities. Finally, by a statistical non-parametric test, we demonstrate that there are no significant differences between our identified cellular automata and the best-known model.

Voluntary leadership and the emergence of institutions for self-governance

Strong local institutions are important for the successful governance of common-pool resources (CPRs), but why do such institutions emerge in the first place and why do they sometimes not emerge at all? We argue that voluntary local leaders play an important role in the initiation of self-governance institutions because such leaders can directly affect local users’ perceived costs and benefits associated with self-rule. Drawing on recent work on leadership in organizational behavior, we propose that voluntary leaders can facilitate a cooperative process of local rule creation by exhibiting unselfish behavior and leading by example. We posit that such forms of leadership are particularly important when resource users are weakly motivated to act collectively, such as when confronted with “creeping” environmental problems. We test these ideas by using observations from a laboratory-in-the-field experiment with 128 users of forest commons in Bolivia and Uganda. We find that participants’ agreement to create new rules was significantly stronger in group rounds where voluntary, unselfish leaders were present. We show that unselfish leadership actions make the biggest difference for rule creation under high levels of uncertainty, such as when the resource is in subtle decline and intragroup communication sparse.
