Classic theories of migration describe international migration as one-way movements and investigate the cultural adjustment of migrants into a “majority society”. Contrary to this view, the article raises the question of new conceptual possibilities to describe migrants’ assimilation and acculturation without conceptually focusing on a nation-state frame. In doing so, it makes reference to theories of transnational migration which define migration as a circular process connecting both sending and receiving contexts. This perspective enables, first, to analyze “structural assimilation” as multiple simultaneous inclusions of individuals into societal institutions in different nation-state locations. Secondly, it suggests to consider acculturation as a cultural adjustment of migrants’ knowledge patterns, which goes hand in hand with the maintenance of cultural “otherness”. 相似文献

The article examines the institutional infrastructure that supports the foreign aid flows in the mcrocredit sector in postconflict Bosnia and Herzegovina. It documents the mobilization of transnational networks between different international agencies in the course of the policy formulation and implementation, and elicits the effects that certain network attributes exert on the policy choices made by individual organizations. How and why do international governmental and nongovernmental organizations, with at times conflicting goals, join forces in such networks? More important, whose goals are eventually implemented, and under what conditions? Whose goals are diluted in the process of network mobilization? What are the policy implications of such "battles" for the postconflict reconstruction? The article seeks some answers to these questions, demonstrating how transnational networks intermediate between the organizational goals and the final policy outcomes that result from such a network–based mode of global governance in postconflict regions. 相似文献

Pursuant to the Polish Weapons and Ammunitions Law, muzzle‐loading black powder weapons, manufactured before 1885, or their replicas, as well as suitable projectiles, can be possessed legally without registration and special licenses. The aim of the study was to assess the penetration depth of projectiles fired from a black powder weapon, replica of Colt Navy of 1851, in 20% gelatin blocks and to compare the obtained results with the actual injuries found on autopsy of a 78‐year‐old man who had committed suicide. In the experiments, we used the black powder weapon and ammunitions, as well as gelatin blocks serving as a soft tissue model. We ascertained that solid spherical projectiles fired from black powder weapons cause extensive injuries, especially in the initial segment of the wound canal. Additionally, based on the presence and location of the wad in the wound canal, the distance from which the shot was fired can be determined. 相似文献

ABSTRACTDoes the art of crafting and amending a constitution lead to an internal consistency among constitutional provisions, and if so, what effect does that have on countries’ democratic performance? Drawing from theoretical claims on the separation of power and electoral legitimacy, this article develops a concept that identifies the institutional characteristics of consistency and inconsistency in the constitutional design with the example of the presidency. Empirically, this concept is focused on aligning or counterbalancing the mode of presidential election and the de jure power of the president. Based on a comparative perspective of republican parliamentary and semi-presidential systems, the article focuses on the empirical trends of consistent and inconsistent design and addresses their effect on democratic development. The findings show a balance between consistent and inconsistent design in terms of quantity. The influence on democratization varies considerably across different measures but I find significant support for a positive effect of inconsistency on liberal democracy, freedom, horizontal accountability and the rule of law. 相似文献

Federal programs have consistently encouraged ever-lower-income households to buy homes, despite concerns about the long-term sustainability and desirability of homeownership from the perspective of wealth-building, especially since the recent housing market collapse and the epidemic of mortgage foreclosures. We ask in this paper: can very low-income households build wealth through sustainable homeownership, with the aid of an innovative public program? We answer this question by examining 122 very low-income households who purchased their homes between 1996 and 2007 after completing an extensive asset-building and homeownership education/counseling program offered by the Housing Authority of the City and County of Denver (DHA), called HOP. We analyze our own longitudinal surveys and focus groups, as well as data compiled from administrative agency sources, real estate records, and longitudinal census data from the Neighborhood Change Database and the Piton Foundation's Neighborhood Facts Database. We find that homeownership attained through HOP typically did provide very low-income households with opportunities to build home equity (both absolutely and relative to generic homeowner cohorts in Denver) and net wealth, although this was contingent on time of purchase and ethnicity. Our multivariate analyses revealed that changes in annualized home equity appreciation were associated with the ethnic composition of the neighborhood and age of property. Annualized wealth accumulation was associated with annualized home equity appreciation, being married throughout the tenure of homeownership, and year of home purchase. HOP homebuyers received exceptionally favorable initial mortgage terms and conditions, often enhanced with down-payment assistance from their own DHA escrow account or from local housing and neighborhood development organizations, resulting in a dramatically low rate of default and foreclosure to date. Moreover, HOP homebuyers were not immune to financial stresses, and the continuing lack of wealth for many makes them vulnerable to future interruptions in primary wage earner's employment or health. We discuss the implications for low-income homeownership policy and argue that the goal of expanding homeownership opportunities should not be abandoned. 相似文献

Public administration scholars have little understanding of the operation of values within public sector organizations. Because the institutional values literature suggests that behavior consistent with American values by public organizations and officials can make a difference in successful policy outcomes, this research focuses on identifying the espoused and enacted value perspectives for two sets of U. S. government officials, presidents and senior executives. Through a content analysis of agency mission statements and speeches of Presidents Bush, Clinton and Bush, a subject matter analysis of executive orders, and a survey of senior executives, the following information is identified: The three presidents espouse the same set of values (i.e., ethics, performance, and support) in their speeches, but enact only one common value (i.e., commitment) in their executive orders. Although not statistically significant, two (i.e., performance and ethics) of the three top values in the agency mission statements are consistent with the values of the presidents. Senior executive perceptions of the most important values (i.e., authority, reward, and support) differ from the presidents. This unexpected difference lends support to Woodrow Wilson’s politics/administration dichotomy in that senior executives focus on values that address policy implementation while presidents focus on values related to politics. 相似文献

Set against the major restructuring of decision-making processes within local government and the wider modernisation agenda for public services, this paper suggests that the scrutiny process (specifically in relation to local authority health scrutiny) can be described in two analytically different, but not necessarily contradictory, ways. It could be seen as a process to increase the levels of local democracy or as a form of integration across different organisations/sectors. The article is informed from the first half of a three-year evaluation that includes interview and observational data from in-depth case study research in five local authorities and their associated Primary Care Trusts (PCTs). The research highlights examples of health scrutiny in terms of both democratic input and integration/joined-up working by organisations from different public sectors, to facilitate scrutiny reviews and resulting changes. It is suggested that further evaluation of the continued development of health scrutiny will be required to examine the potential longer-term impacts on local governance issues, partnership working and the health of the local population. 相似文献

Limited forensic and clinical experience and the lack of confirmatory testing strategies for synthetic cannabinoids (SC) prevent adequate characterization of SC toxicity and the potential impact on public health. A statewide surveillance system identified a fatality involving a 23‐year‐old man found with a large stab wound to the neck following use of a SC product suspected of containing AM2201. Analytical testing for common SCs, SC metabolites, routine drugs of abuse, and over‐the‐counter medications was performed on heart blood obtained at autopsy. Additionally, assays were performed on the SC raw material and drug paraphernalia found on the decedent. High concentrations of AM2201 were detected in all samples. AM2201 metabolites were detected in postmortem blood. Other than a trace amount of JWH‐073 found in smoke residue, no other substances were detected. Psychiatric complications including self‐induced, lethal trauma can occur after the use of SC products. 相似文献

Antisaccade task performance and mean amplitudes of slow cortical potentials (contingent negative variation—CNV) were investigated in 19 healthy volunteers, 16 schizophrenic patients (SP), and 12 patients with stereotyped form of paraphilia (PP). Compared with healthy subjects, schizophrenic and paraphilic patients committed significantly more erroneous saccades. The clear between‐group CNV differences were observed during the early CNV stage that is associated with cognitive aspects of preparatory set. In SP, as compared to controls, the significant decline of CNV amplitude was found at frontal‐central area. PP have demonstrated the lack of CNV over central and parietal regions, but their CNV amplitudes in frontal area did not differ from values of control group. Thus, two distinct types of CNV abnormalities have been found. The SP results have been interpreted as support for frontal dysfunction in schizophrenia. The disconnection between prefrontal cortex, sensorimotor cortex, and related subcortical structures is hypothesized in paraphilia group. 相似文献

Procedures involved in grooming, bathing, and other pet services can often lead animals to death. Of the necropsies of 1391 animals carried out at a private diagnostic laboratory in Sao Paulo, Brazil from 2004 to 2009, 94 were dogs that died during the above‐mentioned procedures. Young male dogs and small breeds like Poodle Miniature, Yorkshire Terrier, and Lhasa Apso were most frequently observed. Blunt‐force trauma was responsible for the deaths of 31% of the animals, with a higher incidence of trauma to the head, characterized chiefly by fractures and nervous tissue lesions. In the other 69% of cases, the animals showed signs of stress, and died due to pulmonary edema and hemorrhage. As we cannot rule out the intentional character in some situations, this article provides veterinary forensic support for veterinarians and pet owners, especially in lawsuits, helping in finding the cause of animal's death in such pet services. 相似文献
