In this study, we collected self-directed behavior data from one group of free-ranging Tibetan macaques(Macaca thibetana) at Mt. Huangshan, China(September 2012–May 2013) using a combination of behavioral sampling methods including focal animal sampling, behavioral sampling, continuous sampling and instantaneous sampling. Our results showed that females engaged in significantly higher rates of self-directed behavior when they were in proximity to dominant individuals compared to subordinate ones. Conflict losers significantly increased their SDB rates after agonistic episodes, indicating that SDB might also serve as an index of anxiety in M. thibetana. We further found that females significantly increased their SDB rates when focal individual was proximity to weakly affiliation relationship higher rank members than to strongly affiliation relationship higher rank members. If conflicts were not reconciled, the postconflict SDB rates of losers were higher when they stayed with strongly affiliation opponents; if conflicts were reconciled, victims of strongly affiliation relationships opponents engaged in more SDB rates before reconciliation than after reconciliation, while victims of moderately affiliation relationships opponents did not engaged in more SDB rates before reconciliation than after reconciliation. We conclude that both of dominance rank and affiliation relationships might both influence the SDB rates of female Tibetan macaques significantly, suggesting that SDB is not only an index of anxiety in Tibetan macaques, but also can provide a new insight into evaluation of social relationships between individuals.展开更多

Because from this understanding, organizations can restructure processes, reorient teams and implement methodologies to assist in the construction of an evolutionary process of knowledge creation and diffusion aimed at sustainable growth and innovation. The theory of complex social networks has been applied in several fields to help understand organizational cognitive processes. However, these approaches still insipiently consider the analysis of the nestedness and modularity of the studied networks. In this article, we presented an approach that sought to identify patterns of nestedness and modularity in networks of affiliation of people in projects in the organizational context. The study sought to identify these patterns in affiliation networks in a public organization providing information technology services in the period from 2006 to 2013. The detection of these patterns was performed using the NODF (Nestedness metric based on Overlap and Decreasing Fill) algorithm described by <a href="#ref1">[1]</a>. The nestedness and modularity metrics can influence patterns of knowledge creation and diffusion in formal and informal networks constituted for the execution of projects in organizations. This study showed that the network structures of the organization during the study period presented a high degree of nestedness, and it was possible to identify combined structures of nestedness and modularity.展开更多

We collected historical data on the allocation and records of hours worked by people in projects to build an affiliation network. We applied the method of reflections to analyze the data obtained. The constructed model enabled the description of the participation of project team members from the perspective of the creation and diffusion of knowledge in affiliation networks that describe the participation of people in projects, mediated by the knowledge and the capabilities developed for the execution of these projects. A contribution of this work is the construction of indicators related to the process of creation and diffusion of knowledge in the context of the execution of software development and maintenance projects, based on the concepts of diversification and ubiquity applied to the process of knowledge diffusion;an additional contribution is the presentation of an application of the method of reflections in an organizational context applied to the creation and diffusion of knowledge. We found that the application of management models associated with the collaborative method applied to the project development process contributed to the joint growth of diversified and more specialized knowledge alongside the knowledge considered more generic and ubiquitous.

We discuss how s-MCA can be useful to focus the analysis on interesting subsets of events in an affiliation network while preserving the properties of the analysis of the complete network. This unique characteristic of the method is also particularly relevant to address the problem of missing data, where it can be used to partial out their influence and reveal the more substantive relational patterns. Similar to ordinary MCA, s- MCA can also alleviate the problem of overcrowded visualizations and can effectively identify associations between observed relational patterns and exogenous variables.

From July to November 2016, we examined four potential functions of the relaxed open-mouth display during pairwise, intra-unit social interactions among 18 free-ranging adult and sub-adult golden snub-nosed monkeys(Rhinopithecus roxellana) who belonged to three one-male, multi-female units(OMU) at Dalongtan, Shennongjia National Park China. Results showed that: compared with no relaxed open-mouth display,(1) the occurrence of displacement by a dominant individual approaching a subordinate was lower and the distance of the subordinate to the approaching dominant was shorter when the subordinate showed open-mouth display;(2) relaxed open-mouth display reduced the probability of continued attack for victims of aggression and allowed victims to achieve closer proximity to the aggressor during post-conflict periods;(3) relaxed open-mouth display by dominant individuals allowed them to achieve closer proximity to subordinates; and(4) the exchange of relaxed open-mouth display had a greater impact on the outcome of interactions than one individual alone giving this signal. These findings suggest that relaxed open-mouth display serves important functions regarding submission, reconciliation, affiliation and reassurance in coordinating social interactions within OMUs in golden snub-nosed monkeys.展开更多

The study was aimed at identifying possible risk factors and also to compare the relative prevention efficacies of oxytocin or misoprostol within the matrix of these factors. Method: A total of 1800 pregnant women who have received either oxytocin injection or oral misoprostol in third stage of labour as a prophylaxis of postpartum haemorrhage, were enrolled within three health care facilities in Maiduguri, Nigeria. Each patient was observed at parturition and for 24 h after, during which blood lost was estimated to the nearest millilitres. Demographic characteristics were recorded in a structured proforma. The relationship of the occurrence of PPH (occurrence of blood loss > 500 ml) and mean blood loss (MBL) was studied with respect to the prophylactic medication used and some demographic factors. Results: The incidence of PPH was higher in Igbo, and some “minority” tribes of Borno state (Babur, Bura, Mafa). The tribes that constituted the majority of the study population (Kanuri, and Hausa) exhibited low incidences of PPH. Significant relationships were demonstrated between PPH and educational levels and occupations of participants. Conclussions: It was concluded that PPH occurrence is related to tribal affiliation, educational level and occupation, and the relative efficacies of oxytocin and misoprostol varies between the tribal groups.展开更多

Previous researchers found a bias toward the use of male infants for this behavior, but its function is debated. Explanations include three hypotheses: paternal care, mating effort, and agonistic buffering. We studied a group of habituated, provisioned Tibetan macaques to test whether adult males' affiliative relationships with females predicted their use of an infant for bridging. We also examined biases for sex, age, and individual in males' choice of bridging infant. We collected data via all occurrences, focal animal, and scan methods, from August to September 2011 at the Valley of the Wild Monkeys, China. We found that male infants were significantly preferred over females for bridging, but of three male infants in the group, only one was used by all males, while one male infant was used less often than expected. Adult males had females they were significantly more likely to be proximate to and/or to groom, but these corresponded to the mother of the bridging infant for only one male. Our results are most consistent with the agonistic buffering hypothesis: lower-ranked males used the alpha male's preferred bridging infant in an attempt to regulate their interactions with the alpha.展开更多

First, China’s domestic financial market is still at the initial stage of development, and foreign exchange control has put barriers to entry and exit of overseas capital. Strictly speaking, the short-term highly liquid "hot money" does not exist in China, and is referred to as long-term speculative capital in this paper. Second, such capital does not come from trade alone. International trade is only part of corporate business operations, and a more reasonable and complete description is that "overseas capital flows into China through foreign-funded enterprises". Through analysis of the inflow channels, this paper estimates that the stock of long-term speculative capital between 1999 and 2006 stands at almost US$ 400 billion. The year 2006 saw an increase of US$ 98.09 billion, of which US$ 35.4 billion was formed through international trade, which equals to roughly 20% of trade surplus that year. But this does not mean that 20% of trade surplus is long-term speculative capital.展开更多

Explanations include three hypotheses: paternal care, mating effort, and agonistic buffering. We studied a group of habituated, provisioned Tibetan macaques to test whether adult males' affiliative relationships with females predicted their use of an infant for bridging. We also examined biases for sex, age, and individual in males' choice of bridging infant. We collected data via all occurrences, focal animal, and scan methods, from August to September 2011 at the Valley of the Wild Monkeys, China. We found that male infants were significantly preferred over females for bridging, but of three male infants in the group, only one was used by all males, while one male infant was used less often than expected. Adult males had females they were significantly more likely to be proximate to and/or to groom, but these corresponded to the mother of the bridging infant for only one male. Our results are most consistent with the agonistic buffering hypothesis: lower-ranked males used the alpha male's preferred bridging infant in an attempt to regulate their interactions with the alpha.
文摘There are two inaccuracies to the common belief that hot money flows into China through international trade: "hot money" and "trade channels". First, China’s domestic financial market is still at the initial stage of development, and foreign exchange control has put barriers to entry and exit of overseas capital. Strictly speaking, the short-term highly liquid "hot money" does not exist in China, and is referred to as long-term speculative capital in this paper. Second, such capital does not come from trade alone. International trade is only part of corporate business operations, and a more reasonable and complete description is that "overseas capital flows into China through foreign-funded enterprises". Through analysis of the inflow channels, this paper estimates that the stock of long-term speculative capital between 1999 and 2006 stands at almost US$ 400 billion. The year 2006 saw an increase of US$ 98.09 billion, of which US$ 35.4 billion was formed through international trade, which equals to roughly 20% of trade surplus that year. But this does not mean that 20% of trade surplus is long-term speculative capital.
