The Singapore Statement on Research Integrity, articulated during the 2nd World Conference on Research Integrity in 2010, encompasses principles that apply to all research endeavours, including the various disciplines that comprise the field of forensic science Singapore Statement on Research Integrity (2010) (https://wcrif.org/guidance/singapore-statement). Cases of research misconduct and breaches of research integrity in any field undermine the trustworthiness of research and make it difficult if not impossible for others to rely upon and replicate research results. Moreover, problems in the research environment, whether in the academic, public, or private sector, can include bullying and harassment, discrimination, abuse of power and corruption, as well as competitive pressures related to employment and status. 相似文献

Postmortem stability of DNA 总被引:11,自引:0,他引:11
High-molecular-weight DNA was recovered postmortem in sufficient quantities from various human organ tissues as well as from blood, although not all organs were equally well suitable. Good DNA stability was found in brain cortex, lymph nodes and psoas muscle over a period of three weeks postmortem. Spleen and kidney showed good DNA stability up to five days postmortem but after longer periods, rapid degradation was observed. Yields of DNA from blood were not consistent because of the non homogeneity of samples. Blood clots were rich with DNA. Generally, the amount of degraded DNA correlated directly with the duration of the postmortem period. However in some cases, DNA degradation was already prominent after a short period. However in some cases, DNA degradation was already prominent after a short period. Case histories showed that high environmental temperature at the site of death and/or infectious diseases prior to death were the main factors for rapid autolysis. Gradual disappearance to complete loss of the long fragments (15-23 kb) was observed in DNA fingerprinting using the minisatellite probe 33.15. No extra-bands were noted, thus excluding erroneous conclusions. However, evidentiary value of older samples was lower. 相似文献

Headspace gas chromatography was used to determine the concentration of ethanol and methanol in blood samples from 519 individuals suspected of drinking and driving in Sweden where the legal alcohol limit is 0.50 mg/g in whole blood (11 mmol/l). The concentration of ethanol in blood ranged from 0.01 to 3.52 mg/g with a mean of 1.83 +/- 0.82 mg/g (+/- S.D.). The frequency distribution was symmetrical about the mean but deviated from normality. A plot of the same data on normal probability paper indicated that it might be composed of two subpopulations (bimodal). The concentration of methanol in the same blood specimens ranged from 1 to 23 mg/l with a mean of 7.3 +/- 3.6 mg/l (+/- S.D.) and this distribution was markedly skew (+). The concentration of ethanol (x) and methanol (y) were positively correlated (r = 0.47, P less than 0.001) and implies that 22% (r2) of the variance in blood-methanol can be attributed to its linear regression on blood-ethanol. The regression equation was y = 3.6 + 2.1 x and the standard error estimate was 0.32 mg/l. This large scatter precludes making reliable estimates of blood-methanol concentration from measurements of blood-ethanol concentration and the regression equation. But higher blood-methanol concentrations are definitely associated with higher blood-ethanol in this sample of Swedish drinking drivers. Frequent exposure to methanol and its toxic products of metabolism, formaldehyde and formic acid, might constitute an additional health risk associated with heavy drinking in predisposed individuals. The determination of methanol in blood of drinking drivers in addition to ethanol could indicate long-standing ethanol intoxication and therefore potential problem drinkers or alcoholics. 相似文献

In this paper, I shall make the following propositions: in order to conceptually capture and represent the acts of political protest in a state of exception, we will need to reorient and supplement our representational apparatuses and also our theoretical frameworks for thinking about the gendered modes of protest under emergency laws and political abandonment. Through an analysis of the ‘naked protest’ of the Meira Peibis in Manipur, a ‘state of exception’ in democratic India, I shall argue that a series of supplementations to our current thinking on intersectionality, bare life and political subjectivation are required if we are to make sense of political acts of resistance, refusal and disavowal of the law of exception. 相似文献

Although many iterations of the mammy in the last two centuries have received analytical attention, the construction of this figure as asexual or undesiring and undesirable remains to be interrogated. This essay attends to this under-theorised dimension of her image. Resisting a reading of the mammy as fixed in silence, I assert that she might instead ‘say nothing’, and bring into focus a black asexual agency that I call a declarative silence. This strategy of ‘saying nothing’ is then explored in a reading of the withholdings of the character of Mama in Gayl Jones’s neo-slave narrative, Corregidora (1975). 相似文献

The ‘reflexive turn’ transcended disciplinary boundaries within the social sciences. Feminist scholars in particular have taken up its core concerns, establishing a wide-ranging literature on reflexivity in feminist theory and practice. In this paper, I contribute to this scholarship by deconstructing the ‘story’ of my own research as a white, genderqueer, masculine-presenting researcher in Ghana. This deconstruction is based on thirteen months of field research exploring LGBT activism in the capital city of Accra. Using a series of ethnographic vignettes, I examine questions of queer subjectivity, embodiment and self/Other dynamics in the research encounter. Specifically, I interrogate what a reflexive concern for power relations means when researchers share moments of commonality and difference with research participants, here in relation to axes of gender, sexuality, race and class. Finally, I explore the challenge of theorising resistance in light of feminist postcolonial critiques of the politics of representation. I conclude that it is only by locating these tensions and dissonances in the foreground of our inquiries that reflexivity becomes meaningful as a way of rendering knowledge production more accountable and transparent, of practising feminist solidarity, and of excavating our own queer research journeys. 相似文献
