This article explores whether union commitment dampens public sector job satisfaction. By examining the connection between union commitment and two workplace attributes that are presumed to be more prevalent in public sector workplaces—perceptions of higher red tape and greater public service motivation—this article develops three hypotheses exploring the direct and indirect relationships between union commitment and public sector job satisfaction. The findings from a series of structural equation models indicate that union commitment directly increases members’ job satisfaction, but it more prominently increases members’ job satisfaction indirectly by reducing perceived red tape and enhancing public service motivation. 相似文献

Abstract: In response to the unexpected paucity of blood/tissue spatter at the site where a body of an adult woman was dismembered by an electric chainsaw, we dismembered two large pig carcasses with a small electric chainsaw in a controlled environment. These experiments demonstrated first that a large carcass could be easily dismembered by a small electric chainsaw. When the chainsaw bar is held parallel to the ground the majority of the blood and tissue is deposited directly beneath the saw and bar and very little elsewhere. If the discharge chute of the saw however is not oriented directly at the ground, larger amounts of blood and tissue may be sprayed on lateral surfaces or deposited some distance from the chainsaw. The characteristic striations created on the surface of wood as it is cut by a chainsaw can also be found on bony surfaces cut by a chainsaw. 相似文献

Spacepower is a critical element supporting the US national security strategy. As more nations gain access to technology, there is growing concern that space capabilities will be increasingly vulnerable to attack. However, a more insidious problem looms. For the last decade, the development and acquisition of US national security space systems have become more and more troubled with cost overruns and schedule delays. This grave situation has caught the attention of national security leadership and the US Congress. Panels of experts have proposed a litany of remedies. In this paper we explain and illustrate the importance of enhancing space power to better support national security needs and caution that many of the proposed acquisition solutions address symptoms, not the primary cause. As history as shown…if the US offers an inviting target, it may well pay the price of attack. With the growing commercial and national security use of space, US assets in space and on the ground offer just such targets. The US is an attractive candidate for a ‘Space Pearl Harbor’. 1 This is the way the world ends This is the way the world ends This is the way the world ends Not with a bang but a whimper. 2 相似文献

This study evaluated effects of the Iowa Strengthening Families Program, a family-focused universal preventive intervention, on growth patterns of adolescent internalizing (anxiety and depressive
symptoms) and monthly polysubstance use (alcohol, tobacco, marijuana, inhalants, and other illicit drugs), as well as the
association between internalizing and polysubstance growth factors. The sample consisted of rural Midwestern adolescents (N = 383), followed from sixth through twelfth grade. Compared to the control group, the intervention group adolescents showed
a slower rate of increase in internalizing symptoms and polysubstance use. Intervention effects on internalizing symptoms
were similar for boys and girls; however, girls demonstrated a higher overall level and a greater rate of increase across
time. The intervention slowed the rate of increase in polysubstance use significantly more for girls than for boys, although
overall levels of use were lower in the intervention group for both genders. Associations between internalizing and polysubstance
use growth factors were found for girls, but not for boys, suggesting gender differences in psychosocial development.

Qualitative studies of vote buying find the practice to be common in many Latin American countries, but quantitative studies using surveys find little evidence of vote buying. Social desirability bias can account for this discrepancy. We employ a survey‐based list experiment to minimize the problem. After the 2008 Nicaraguan municipal elections, we asked about vote‐buying behavior by campaigns using a list experiment and the questions traditionally used by studies of vote buying on a nationally representative survey. Our list experiment estimated that 24% of registered voters in Nicaragua were offered a gift or service in exchange for votes, whereas only 2% reported the behavior when asked directly. This detected social desirability bias is nonrandom and analysis based on traditional obtrusive measures of vote buying is unreliable. We also provide systematic evidence that shows the importance of monitoring strategies by parties in determining who is targeted for vote buying. 相似文献

This study provides evidence of craniofacial growth variation between the sexes in juveniles of European descent. Data were collected from lateral cephalometric radiographs belonging to the Michigan Craniofacial Growth Study. The collection consists of longitudinal lateral radiographs that represent individuals 5-16 years of age. Each radiograph was manually traced on hyprint vellum from which eight craniometric points were identified. From these points, 20 craniofacial measurements were recorded and then analyzed by means of a canonical discriminant function analysis. Sex classification equations were then created by applying a backward stepwise procedure to the discriminant functions. The analysis demonstrates the presence of sexually dimorphic differences in craniofacial growth. The neurocranium is the most sexually dimorphic region of the juvenile craniofacial skeleton, until the onset of puberty. Size is the main source of variation with males having taller and longer heads than females. Overall, sex classification in the sample ranges from 78 to 89% accuracy. 相似文献

This study characterized the specific offenses for which homeless individuals are arrested and incarcerated. Data were gathered from 581 homeless adults across 6 Oklahoma City shelters. Participants were asked to self-report incarceration history, nights spent in jails and prisons, and the offenses for which they were arrested. Overall, 76% of the sample had ever been arrested. Fifty-seven percent of the sample had been to jail more than 3 times in their lifetime and 13% had ever intentionally been arrested. The most prevalent type of arrest was drug possession (35%), followed by driving under the influence (31%) and disorderly conduct or public drunkenness (28%). Violent arrests, such as assault, robbery, domestic violence, murder, and rape, were the least prevalent type of arrest. In summary, offenses were largely drug and status offenses. These offenses may be prevented through increased substance use treatment accessibility and availability of housing. Policies to increase employment and housing for homeless adults regardless of criminal history should be expanded to reduce the occurrence of justice involvement. 相似文献
