Mental health and firearms in community-based surveys: implications for suicide prevention

Suicide rates are higher among those who own a handgun and among those who [corrected] live in a household with a hand gun. This article examines the association between [corrected] gun ownership and mental health, another risk factor for suicide. Data from the General Social Survey, a series of surveys of U.S. adults, are analyzed to compare general emotional and mental health, sadness and depression, functional mental health, and mental health help seeking among gun owners, persons who do not own but live in a household with a gun, and those who do not own a gun. After taking into account a few basic demographic characteristics associated with both variables, there appears to be no association between mental health and gun ownership. Nor is there any association between mental health and living in a household with a firearm. Findings suggest that the high risk of suicide among those who own or live in a household with a gun is not related to poor mental health. Implications for prevention are discussed.     

Improving throughput for an electronic assembly line using a constraint analysis methodology

Electronic assembly operations are vital to industries such as telecommunications, computers and consumer electronics. This paper presents a constraint analysis methodology for planning and improving electronic assembly operations that draws on concepts from queueing theory, simulation and production planning. The proposed methodology identifies the operational bottleneck and predicts the utilization, throughput and lead time of the assembly line. It also quantifies the relationship between yields and utilization for the assembly operations. A case study is presented that applies the methodology at an Ericsson, Inc., telecommunications equipment assembly facility. The constraint analysis methodology provided valuable decision support as the managers of Ericsson evaluated the costs and benefits of additional production capacity. Although the focus of this paper is electronic assembly operations, the methodology can be applied to general flow line assembly systems with feedback loops for test and rework under dedicated high-volume production.     

Firearm advertising: product depiction in consumer gun magazines

In contrast to tobacco, alcohol, and other consumer products associated with health risks, we know very little about how firearm manufacturers advertise their products. The authors examined advertisements for firearms in all 27 ad-accepting magazines listed in Bacon's Magazine Directory "guns and shooting" category. Sixty-three manufacturers spent an estimated $1,195,680 on firearm advertising during the month studied. Annual advertising costs ranged widely; manufacturers spent an estimated $28.16 in advertising per firearm produced. Firearms generally were presented as a part of a lifestyle. Self-protection was noted infrequently in the advertisements. By contrast, attributes of the gun, typically technological characteristics, were noted in almost every advertisement.

论驯鹿鄂温克人的驯鹿文化

驯鹿鄂温克人是我国鄂温克族中的特殊群体。他们生活在兴安岭的深山老林,以饲养驯鹿谋生。在漫长的历史发展进程中,驯鹿鄂温克人在狩猎驯鹿和使用驯鹿以及饲养驯鹿的生产生活实践中,用共同的劳动和智慧创造出了我国独一无二而独具风格的驯鹿文化。我们拟从人类文化学与民族文化学的理论视角,对这一特殊族群的驯鹿文化形态进行客观实在的分析和讨论。     

Does multinational activity displace trade?

Using two-panel data sets on the operations of U.S. multinational firms abroad and the operations of foreign multinational firms in the United States, this article examines the empirical relationship between international trade and multinational activity. The evidence supports the conclusion that multinational activity and trade are complementary activities, particularly multinational activity and intrafirm trade. This empirical result is consistent with the theoretical reasons one might expect a complementary relationship between the two activities and is also robust to different approaches and specifications.
