Mexican official confirms cartel gunmen forced a dozen tanker trucks to dump gasoline at gunpoint_我的网站

A | 北京时间1月14日早些时候，TechCrunch报道说，密歇根州立大学的研究人员正在探索社交媒体成瘾的概念。    A Mexican official on Monday confirmed a shocking video that emerged over the weekend of cartel gunmen forcing the drivers of about a dozen tanker trucks to dump their entire loads of gasoline into a field.The official, who was not authorized to be quoted by name, said the incident occurred last week in the border city of Matamoros, across from Brownsville, Texas, and was under investigation.The official said the gunmen had apparently forced the truck drivers to line their parked vehicles up on a dirt road to dump their cargo.Asked about the videos, President Andrés Manuel López Obrador acknowledged “there is resistance from criminals” in the area, long known for cartel violence, adding that “We continue to confront them.”In the video, a presumed member of the cartel can be heard mentioning the Gulf cartel faction known as The Scorpions, and saying all trucks carrying gasoline would suffer the same fate unless “they get in line,” or pay protection money to the gang.In the video, open valves on the bottom of the tankers could be seen spewing gasoline like fire hoses, as armed men looked on. “This is going to happen to all the grasshoppers,” a man's voice can be heard saying, an apparent reference to Mexican gang slang that compares those who “jump” through a cartel's territory to the hoppy insects.Criminals in the border state of Tamaulipas have long drilled into state-owned pipelines to steal fuel, but now an even more complex situation is taking place.Because of cross-border price differentials, it is sometimes profitable to import gasoline from Texas and sell it in Mexican border cities in Tamaulipas. López Obrador's administration has long complained that many of the truckers mislabel their cargo to avoid import tariffs.Others legally import U.S. gasoline, a practice the Mexican government dislikes because it reduces sales for the state-owned oil company.“We are there to protect the citizens of Tamaulipas, so they don't have to buy stolen or smuggled fuel,” López Obrador said Monday.But the Gulf drug cartel apparently demands money from both legal importers and those who seek to avoid paying import duties.One businessman who asked not to be identified for fear of reprisals said the gang is demanding a payment of $500 per truck even to allow legally imported gasoline through the city of Matamoros, an important border crossing.The businessman added that Tamaulipas authorities often provide escorts for tanker trucks precisely to prevent such attacks.It was the latest instance of lawlessness in Matamoros, where in March four Americans were shot at and abducted by a drug gang. The Americans were found days later, two dead, one wounded and without physical injuries.____Follow AP’s coverage of Latin America and the Caribbean at https://apnews.com/hub/latin-america。他们发现，在日常生活中，使用社交媒体网站的人表现出与可卡因或海洛因上瘾者相似的行为特征。

B | 相关论文已发表在《行为成瘾杂志》上。该研究首先要求71名参与者使用Bergen-Facebook成瘾量表对他们使用Facebook的情况进行评分。然后，受试者继续完成爱荷华游戏任务（IGT），这是一个评估决策能力受损程度的经典研究工具。

C | 具体方法是向参与者展示四包卡片和四组卡片。每张卡片都显示了获得或损失的金额。

D | 要求参与者在其中进行选择，以最大限度地提高收益。正如研究中解释的那样，“参与者还被告知，有些卡片比其他的好，如果他们想做得好，就应该避免坏卡片，选择好卡片。”研究人员发现，声称自己是Facebook过度用户的参与者在IGT上的表现比他们的同龄人差，他们选择了两张“坏”卡片，提供即时B。

E | 但最终导致了损失。在IGT的后一部分，当参与者有足够的时间观察卡片并知道哪些卡片预测了最大的风险时，实验中显示的行为差异具有统计学意义。

F | 从额叶脑损伤患者到海洛因依赖者，IGT已被广泛应用于各个研究领域，但作为一种检测社交媒体依赖者的手段，它仍然是一种创新的方法。随着结构研究的不断深入，研究者们可以肯定地将现有的学习物质成瘾的方法论框架应用于社交媒体用户。虽然上述研究范围较窄，但很有意思，为后续研究提供了一些方法。研究人员已经意识到，在理想的研究状态下，研究人员可以观察参与者的社交媒体使用情况，并根据他们的行为而不是他们填写的调查对他们的社交媒体使用情况进行排名。未来的研究也可以更深入地应用于不同社交网络的过度使用用户。目前，这项研究只关注Facebook的使用，“因为它是当今世界上使用最广泛的社交网络”，但人们可以预期，Instagram每月拥有超过10亿用户，而Twitter上瘾者则少得多。
