专利价值之谜及其理论求解

在当今专利制度中,尽管多数专利的价值往往少于专利申请和维持的费用,但专利申请案和授权量却急剧增长。这被称之为专利价值之谜,其理论求解应从专利获取的目的出发。竞争者之所以通过申请大量专利的方式形成专利组合,是因为它既是竞争者的防卫之盾,也是其进攻之矛。非竞争者所拥有的专利组合备受人们指责;但事实上,非实施企业拥有的专利质量大都可靠。此外,大量专利的形成是专利制度为鼓励专利竞赛有意而为的结果。因为由大量专利结合而成的专利组合能够区分市场上真正的创新者和模仿者,从而保障创新者的竞争优势。我国应该采取合理的措施鼓励我国的创新企业形成自己的专利组合。     

The intersection of race and gender: an examination of sentencing outcomes in North Carolina

This study examines the intersection of offenders’ race and gender in the sentencing process using data on felony cases sentenced in North Carolina. Analyses examine the likelihood that charges were reduced in severity between initial filing and conviction, the likelihood of imprisonment, and the length of sentence imposed, and test whether race affects punishment similarly for men and women. Results indicate that status characteristics predict both reductions in charge severity and the severity of the final sentence, and that racial disparity is conditional on gender. However, the results are not entirely consistent with predictions derived from the extant literature. Gender significantly predicts case outcomes at each stage, but black men were not uniformly disadvantaged, and black women received the least severe treatment in two out of four analyses. Theoretical implications for the intersection of race and gender in sentencing theories are discussed.     

Examining the prevalence and correlates of a ‘senior citizen discount’ in US federal courts

Few studies focus on age as a factor influencing judicial decision-making, in spite of the widespread use of age as a control variable. Although the limited research to have done so is inconsistent, most scholars agree that age may be race- and/or gender-graded in a manner that produces more severe sentences for certain race–gender–age combinations, especially for young males who are Black or Latino. Less consensus exists with regard to whether older defendants are granted more leniency in the sentencing process and, if so, if the effects of older age are also race- and/or gender-graded. The present study examines this question by examining data from the United States Sentencing Commission. The data presented reveal three noteworthy findings. First, a ‘senior citizen discount’ exists insofar as judges afford more leniency in sentencing to older offenders than their younger counterparts. Second, compared to older males, older females were treated with greater leniency by judges. Finally, whereas Latinos 60 and over were treated with greater severity at the stage of incarceration compared to similarly situated Whites, Blacks received shorter sentence lengths on average. These results are analyzed within the framework of the focal concerns perspective.

IMPACT OF VICTIMIZATION ON RESIDENTIAL MOBILITY: EXPLAINING RACIAL AND ETHNIC PATTERNS USING THE NATIONAL CRIME VICTIMIZATION SURVEY

Criminal victimization is known to influence households’ moving decisions, but theories suggest that the processes leading to a moving decision can vary across racial and ethnic groups. Drawing from current literature, we hypothesized that victimization would have a stronger effect on moving decisions for Whites than for Blacks or Hispanics, and that racial/ethnic residential segregation would moderate the impact of victimization on mobility. Using a longitudinal sample of 34,134 housing units compiled from the National Crime Victimization Survey for the 40 largest metropolitan areas in the United States (1995–2003), we found results that both support and contradict the hypotheses. Specifically, White residents display consistent evidence that victimization is a significant predictor of household mobility. Blacks and Hispanics, in contrast, are more varied in their moving behavior after victimization. In addition, significant differences exist among these groups in responses to victimization and in how mobility is influenced by residential segregation. Higher levels of residential segregation play a part in the victimization–mobility relationship among Blacks in a way that is more complex than we hypothesized.     

Child protection as surveillance of African American families

The over-representation of black children in US out of home care results from racial bias in placement decisions and a political choice to address startling rates of child poverty by investigating parents instead of tackling poverty's societal roots. The impact of state disruption and supervision of African American families is intensified when it is concentrated in inner-city neighbourhoods – the system's ‘racial geography.’ A small case study of a black neighbourhood in Chicago with high rates of out of home placement found profound effects on both family and community social relationships, as well as reliance on child protective services for financial assistance, linking surveillance of black families to the neoliberal shrinking of public programmes. The surveillance of African American women by the child welfare system is also intensified by these women's disproportionate involvement in the prison system. Acknowledging racial bias in child welfare reveals the need to radically transform the system from one that relies too much on punitive disruption of families to one that generously supports them.     

Determination of average vehicle speed utilizing reverse projection

Reverse projection photogrammetry has long been used to estimate the height of an individual in forensic video examinations. A natural extrapolation would be to apply the same technique on a video to estimate the speed of an object by determining the distance traveled between two points over a set amount of time. To test this theory, five digital video recorders (DVRs) were connected to a single fixed camera to record a vehicle traveling down a track. The vehicle's speed was measured through Doppler radar by a trained operator and the speedometer of the vehicle was also recorded with a video camera. The recorded video was examined and the frames that best depict the beginning and end of the vehicles course were selected. Two reverse projection photogrammetric examinations were performed on the selected frames to establish the position of the vehicle. The distance between the two points was measured, and the time elapsed between the two points was examined. The outcome provided an accurate speed result with a standard degree of uncertainty. This study proves the feasibility of using video data and reverse projection photogrammetry to determine the speed of a vehicle with a limited set of variables. Further research is needed to determine how additional variables would impact the standard degree of uncertainty.     

Fighting antisemitism with numbers in early twentieth-century Britain

ABSTRACT

In the 1920s and 1930s, the Jewish Health Organization of Great Britain (JHOGB) and its president, Redcliffe Nathan Salaman, championed the collection and analysis of demographic data about the Anglo-Jewish community as a way to counter rising antisemitism. In this article, Endelman discusses the belief in the ability of statistical research to undermine lies and distortions about the Jews of Britain that rested on untested Enlightenment assumptions about human nature and the sources of human behaviours and sentiments. While the JHOGB’s faith in statistical research as a bulwark of counter-propaganda never faltered, and while it obtained funding for a handful of projects, it failed to convince the leaders of Anglo-Jewry of the necessity to create and support a permanent statistical bureau. With the onset of the Second World War, the organization ceased its work, as more pressing communal priorities, especially caring for refugees from Nazism, rose to the fore.     

Interracial marriages in twentieth-century Cape Town: evidence from Anglican marriage records

ABSTRACT

One of the most controversial laws promulgated by the National Party as part of South Africa’s mid-twentieth century apartheid policies was the 1949 Prohibition of Mixed Marriages Act. This Act stipulated that ‘a marriage between a European and non-European may not be solemnized, and any such marriage solemnized in contravention of the provisions of this section shall be void and of null effect’. We use more than 23,000 newly-transcribed Anglican marriage records of Cape Town for the period 1911 to 1964 to show that the Act had mostly followed, and not led, changing interracial marriage practices. In the years before the Act’s promulgation, interracial marriages were rare and on the decline, despite the fact that apartheid-era policies had not yet been institutionalized. Our results suggests that marriage behaviour in Cape Town, and probably in South Africa more generally, was shaped by racial stratification early in the twentieth century. The Prohibition of Mixed Marriages Act of 1949, although devastating to those affected, was a correlate to rather than the cause of changing marriage behaviour.     

“That shit doesn't fly”: Subcultural constraints on prison radicalization

Many observers describe prison subcultures as inherently and irredeemably antisocial. Research directly ties prison subcultures to violence, gang membership, and poor reintegration. In extreme cases, research has also suggested that prison subcultures contribute to incarcerated people joining radical groups or embracing violent extremist beliefs. These claims, however, ignore key differences in the larger cultural and social context of prisons. We examine the relationship between prison subcultures and prison radicalization based on semistructured qualitative interviews with 148 incarcerated men and 131 correctional officers from four western Canadian prisons. We outline several imported features of the prison subculture that make incarcerated people resilient to radicalized and extremist messaging. These features include 1) national cultural imaginaries; 2) the racial profile of a prison, including racial sorting or a lack thereof; and 3) how radicalization allowed incarcerated men and correctional officers to act outside the otherwise agreed-to subcultural rules. Our research findings stress the importance of contemplating broader sociocultural influences when trying to understand the relationship between radicalization and prison dynamics and politics.
