Sustainable Transformation of Resettled Communities for Landless Peasants: Generation Logic of Spatial Conflicts

Urbanization in China has resulted in serious conflicts. Landless peasants are resettled between urban and rural areas in transitional communities. where their rural lifestyles often lead to spatial conflicts. We proposed a conceptual model to provide theoretical guidance for the governance of spatial conflicts and the sustainable transformation of resettled communities. Using field observations and semi-structured interviews, we examined 10 resettled communities in Hangzhou, China. The use of grounded theory to code the interview texts yielded 71 initial concepts and 22 categories that we then refined into six main categories: community physical environment (e.g., quality of private housing), community communication environment (e.g., heterogeneity of community population), landless peasants’ risk perceptions (e.g., impacts on social psychology), community governance capacity (e.g., trust in community’s self-governing organizations), residents’ space perceptions (e.g., awareness of space rights), and space competition behavior (e.g., fighting for public space). Finally, we applied social combustion theory to construct a logical relationship between the core category and main categories. The results show that changes in the physical and communication environments are the root elements (“combustion substances”) of spatial conflicts; the driving factors are landless peasants’ risk perceptions and community governance capabilities; direct elements (“ignition temperature”) are residents’ space perceptions and space competition behavior. Strategies for sustained transformation in resettled communities should prioritize gradual transitions of community space, improve support mechanisms for landless peasants, optimize community governance mechanisms, and cultivate awareness of community rules. This study aids the understanding of the inner mechanism for the sustainable development of resettled communities and has implications for other countries and regions in similar contexts.

Electrocommunication signals indicate motivation to compete during dyadic interactions of an electric fish

Animals across species compete for limited resources. While in some species competition behavior is solely based on own abilities, others assess their opponents to facilitate these interactions. Using cues and communication signals, contestants gather information about their opponent, adjust their behavior accordingly, and can thereby avoid high costs of escalating fights. We tracked electrocommunication signals, in particular “rises”, and agonistic behaviors of the gymnotiform electric fish Apteronotus leptorhynchus instaged competition experiments. A larger body-size relative to the opponent was the sole significant predictor for winners. Sex and the frequency of the continuously emitted electric field were only mildly influencing competition outcome. In males, correlations of body-size and winning were stronger than in females and, especially when losing against females, communication and agonistic interactions were enhanced, hinting towards males being more motivated to compete. Fish that lost competitions emitted the majority of rises, whereby their quantity depended on the competitors’ relative size and sex. The emission of rises was costly since it provoked ritualized biting or chasing behaviors by the other fish. Despite winners being accurately predictable based on rise numbers already after the initial 25 minutes, losers continued to emit rises. The number of rises emitted by losers and the duration of chasing behaviors depended in similar ways on physical attributes of contestants. The detailed evaluation of these correlations hint towards A. leptorhynchus adjusting their competition behavior according to mutual assessment, where rises could signal a loser's motivation to continue assessment through ritualized fighting.

COMPARISON OF SOME BIOCHEMICAL VARIABLES DURING KICKBOXING COMPETITIONS

Background: Kickboxing is a high-intensity, intermittent combat sport, which is characterized by short-term complex abilities and tactical key movements. In this study, it was aimed to investigate the factors related to variability in potential biochemical parameters and competition behavior of high-level kickboxing athletes. Methods: Blood samples of athletes, which were obtained pre- and post-maximal competition applied in accordance with the period, were investigated. In the study, a total of 50 athletes, which consisted of 39 male and 11 female amateur athletes with a mean age of 20.08 ± 6.33. Results: Significant differences were determined in the Body Mass Index (BMI) values between females and males. It was determined that athletes’ Aspartate Aminotransferase (AST), Alanine Transaminase (ALT), Total Oxidant Level (TOL) and Malondialdehyde (MDA) values were significantly increased pre- and post-competition while it was determined that Total Antioxidant Level (TAL) were significantly decreased (p<0.05). According to the findings, it was observed that there were statistically significant differences between serum antioxidant, oxidant and liver enzymes of amateur level kickboxing athletes pre- and post-competition. Conclusion: In conclusion, considering the effects of effects of strikes received on the chest area and the effects of the liver, which is located in the intersection of all metabolic pathways, on muscle, increases in liver enzymes is an ordinary situation. It was finally observed that the strikes received caused increases in liver enzyme levels while decreased TAL and increased TOL levels were encountered based on antioxidant enzyme levels spent for removing the free radicals formed as a result of heavy exercise. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0746/a.php" alt="Hit counter" /></p>

Investigating the Effect of Flock Size on Vigilance in the American Coot (Fulica americana) in Relationship to Habitat

Among many anti-predator behaviors, vigilance is observed in many species and plays an important role in survival. In this study, we investigated the effect of flock size on vigilance in American Coots (Fulica americana)foraging on land and water, by observing individual birds in these habitats and recording the time spent scanning (i.e., vigilance). Mean flock size was larger on land compared to water and vigilance negatively correlated with flock size. Birds in water were more vigilant compared to on land, regardless of whether they were foraging alone or in flocks. However, the effect of flock size on vigilance showed a weak linear correlation as it was possible that other factors (e.g., human habituation, food kleptoparasitism, or scramble competition) could have also played a role in shaping vigilance. These results suggest that there is a relationship between flock size and vigilance, which are related to previous researches that show a negative correlation between vigilance and flock size.

PERANG TARIF PENYEDIA LAYANAN OJEK DALAM JARINGAN DALAM PERSPEKTIF HUKUM PERSAINGAN USAHA DI INDONESIA

Penulisan jurnal ini bertujuan untuk mengetahui serta memahami perang tarif pada penyedia layanan ojek dalam jaringan dalam perspektif hukum persaingan usaha di Indonesia dan juga untuk mengetahui tugas Komisi Pengawas Perlindungan Usaha dalam mengawasi kasus persaingan usaha. Metode penelitian yang digunakan dalam jurnal ini adalah penelitian hukum normatif yang dimana mengkonsepsikan hukum dalam bentuk hukum yang sudah tertulis seperti undang-undang tertulis, dan bersifat deskriptif yaitu diartikan penelitian yang dilakukan dengan cara menggambarkan secara lengkap. Hasil penelitian menunjukkan bahwa perang tarif antara para penyedia layanan ojek daring yaitu PT. X dan PT. Y terdapat beberapa tanda dan pola praktik predatory pricing penetapan harga oleh perusahaan transportasi daring. Menurut UU No. 5 Tahun 1999 dikatakan bahwa PT. X dan PT. Y melawan hukum dengan tidak mengikuti aturan Pasal 5 ayat (1) UU No. 5 tahun 1999. Berdasarkan pasal tersebut sudah terbukti bahwasanya pihak PT. X dan PT. Y melanggar karena kedua perusahaan ojek daring tersebut melakukan perjanjian antara keduanya untuk menaikkan harga pada pelanggan ojek daring.

Y ini berperan sebagai salah satu lembaga penegak hukum, dan tanggung jawabnya mengawasi perilaku persaingan usaha tidak sehat para pelaku usaha. In order to writing this journal is to know and understand the rates war between two corps who will be start to be some perspective from business competition in Indonesia and also to determine the role of the Business Protection Supervisory Commission. The research method used in this journal is normative legal research which conceptualizes law in the form of written law such as written law, and is descriptive in nature, which is defined as research that provides data about a situation or social symptoms that develop in the midst society in accordance with the facts and without any engineering. The results show that the tariff war between online motorcycle taxis, namely X Ltd. and Y Ltd., has several signs and patterns of predatory pricing practices by online transportation companies, including discounts that reach unreasonable prices, long-term promotions that exceed standards. With that it can be said that X Ltd. and Y Ltd. violate Article 5 paragraph (1) of Law no. 5 of 1999. From this article, it has been proven that X Ltd. and Y Ltd. violated it because the two online motorcycle taxi companies entered into an agreement between the two of them to increase prices for online motorcycle taxi customers. In business competition, there is the Business Competition Supervisory Commission (KPPU), which in the business competition case between X Ltd. and Y Ltd. plays a role as a law enforcement agency, and its responsibility is to supervise the unfair business competition behavior of business actors.

Timing of Adopting a Flexible Manufacturing System and Product Differentiation

Based on a circular product-space model with continuous time, we investigate a dynamic game in which each firm decides whether and when to adopt a flexible manufacturing system (FMS) at the beginning of the game and then chooses its quantity supplied at each time. We show that the equilibrium outcomes may be either joint adoption at the beginning of the game or sequential adoption, depending on the range of an initial adoption cost. For a given basic product, we find that a larger product differentiation decelerates the adoption of FMS. We also investigate competition behavior when the decisions on product locations are made endogenously and conduct welfare analysis, showing that there is market failure in the adoption timing choices.
