bet365 app download newspaper comprehensively reports from foreign media According to the official website of Michigan State University, USA，Zachary Neal, a professor in the school’s Department of Psychology, re-evaluates the famous theory “the power bet365 app download” in the field of social sciences。Research results show，In terms of learning new information，The other party only has some friendship with me，It’s not important to be the closest friend，It is important to expose yourself to other social circles。

"The power bet365 app download" theory was proposed by American sociologist Mark Granovetter in 1973，Being widely cited in the next 50 years or so。This theory holds that，The value of weak relationships such as casual acquaintances is not low，Opposite，They are a very useful source of new information such as job opportunities。From public health to physics，This theory has a wide range of applications。However，Although influential，The evidence is not that clear，And some scholars have questioned this theory。Neal re-evaluated the "strength bet365 app download" theory and proposed，First，Every theory contains presuppositions，The presupposition may not be satisfied in specific cases；Secondly，Facing situations that are inconsistent with the default，A certain theory may not necessarily exhibit robustness。Starting from these two aspects，Neal conducted two sub-studies。

The first sub-study utilizes publicly available data from a large social network data repository，Neil assembled a corpus of 56 empirical social networks。Analysis display，On average，These social networks can satisfy one of the presuppositions of the "strength bet365 app download" theory，That is, the overlap degree of the friendship network between the two parties is positively correlated with the strength of the relationship；Almost meets the second default，That is, a strong relationship is not a bridge；Does not meet preset three，That is, bridges are all weak relationships。This means that social networks as a whole do not meet all the presuppositions of this theory。In the second substudy，Neil’s information diffusion dynamics through 2500 simulated social networks，Tested the robustness of the utility prediction that “weak ties are useful for acquiring new information”。He discovered，When the theoretical presupposition of "the power bet365 app download" can be satisfied，Weak ties are indeed particularly useful for acquiring new information，Thereby supporting the validity of the theory；When the theoretical presuppositions cannot be satisfied，As is common in empirical social networks，The strength bet365 app download is not too prominent。In the latter case，Acquisition of new information depends on bridging relationships，And a "strong bridge" with high bandwidth is more useful than a "weak bridge"。The above results show，"The power bet365 app download" is generally established，But its prediction is not reliable for situations that do not meet the preset。

Neil said，This new study should not be thought to undermine the value of the “strength bet365 app download” theory。If one considers that empirical support for any theoretical prediction is limited to cases that satisfy the theoretical presuppositions，“The power bet365 app download” is no exception。In addition，The conceptual and methodological contributions of the “strength bet365 app download” theory should not be ignored。On the one hand，The abstract structural concept of "bridge" was mainly the research field of graph theorists at that time，The concept of "relationship strength" is studied by sociologists。Theorizing the link between bridges and relationship strength，Established connections between different research fields，Inspiring more in-depth exploration for decades to come。On the other hand，Identifying bridges in social networks, especially large networks, was extremely challenging at the time，Measuring relationship strength is relatively simple using traditional data collection methods。Theorizing the connection between the two，Identified strength as a possible (albeit imperfect) proxy for bridging。The actual situation today is very different from that back then。The concept of bridge is well known and widely used in social sciences，It is also easier to measure the bridging nature of a relationship directly。These changes allow researchers to independently measure relationship strength and bridging，Consider their functions separately，Get a more detailed understanding。

Neil’s suggestion，Future research related to “The Power bet365 app download”，When results are observed that contradict the predictions of the theory，To verify whether the theoretical presuppositions have been violated；In addition，In exploring the importance of different types of relationships to information diffusion and other processes，To measure relationship strength and bridging separately，Then consider the role of bridges and weak ties respectively。Is it stronger or weaker than the connection with others，We need to pay more attention to whether this connection can help people get out of the social bubble。This study shows，One does not have to strive to have many casual acquaintances rather than a few close friends in order to keep up with the latest news and trends。Opposite，If you want to stay informed，Make sure you communicate with a variety of people，Including those in completely different social circles。In addition，No matter whether the relationship is strong or weak，Having bridges across social barriers is a way to break down polarization and misunderstandings，Bridging social relationships connect people to new information and new ways of thinking about the world。
