Organisational and procedural justice: a review of the literature and its implications for policing

Organisational justice and procedural justice are complementary concepts that relate to the way individuals make judgments about fairness and outcomes when considering their interactions with others. Organisational justice and procedural justice comprise largely the same concepts, although their foci are different. Inwardly facing organisational justice is particularly concerned with the implications of justice judgments on staff attitudes, staff retention, workplace relations, productivity and performance. Outwardly facing procedural justice is—in the context of this paper—concerned with the interactions between police organisations and the public. This paper reports on the findings of a systematic review of the literature examining organisational and procedural justice in policing. We searched three comprehensive databases for literature on these themes. Fifty-seven empirical items were returned; five relating to organisational justice and police organisations, and 52 exploring procedural justice and police–public interactions. We explore this literature, and consider the implications for policing. We do so to set the scene for the other papers in this special edition. We conclude by noting that the extant literature has much to help police organisations better manage their internal and external relations, but that further effort should be made to turn empirically sound and theoretically interesting research into easily digestible and practically applicable models for police practitioners at all levels of the organisation

Interphase cytogenetics using biotin and digoxigenin labelled probes I:relative sensitivity of both reporter molecules for detection of HPV16 in CaSki cells

This study was undertaken to develop technology for the detection of nucleic acid using two different DNA probe reporter molecules, the ultimate aim being to differentially label two nucleic acids within the same nucleus. Digoxigenin and biotin were used to label DNA probes. The absolute and relative sensitivity of digoxigenin and biotin labelled DNA probes for detecting integrated human papilloma virus 16 (HPV16) was investigated in CaSki cells by non-isotopic in situ hybridisation (NISH). Several methods for the detection of labelled probes were also investigated. The optimal sensitivity of digoxigenin labelled probe was equivalent to that of biotin when alkaline phosphatase was used as the final detector. The median number of discrete viral signals discernible in each cell with the most sensitive detection system was seven to eight with both labelled probes. The average number of HPV16 genomes in each CaSki cell, derived by dot blot hybridisation, was about 270. The calculated absolute sensitivity of NISH for viral detection in this system is complex because of variation of signal size and number. Nevertheless, one signal per nucleus equates to as little as 30 to 40 viral copies, and probably much less. The ability to distinguish up to 15 discrete signals with both digoxigenin and biotin labelled probes in the nuclei of CaSki cells indicates that these methods will be useful in interphase cytogenetics in material routinely fixed in aldehyde

Molecular events in uterine cervical cancer

OBJECTIVE: To review the literature regarding the molecular events which occur in the development of uterine cervical cancer, with particular reference to human papillomavirus (HPV) infection. METHODOLOGY: Bibliographic searches of Medline and the ISI citation databases using appropriate keywords, including the following: papillomavirus, cervix, pathology, cyclin, chromosome, heterozygosity, telomerase, smoking, hormones, HLA, immune response, HIV, HSV, EBV. CONCLUSIONS: It has become clear that most cervical neoplasia, whether intraepithelial or invasive, is attributable in part to HPV infection. However, HPV infection alone is not sufficient, and, in a small proportion of cases, may not be necessary for malignant transformation. There is increasing evidence that HPV gene products interfere with cell cycle control leading to secondary accumulation of small and large scale genetic abnormalities. This may explain the association of viral persistence with lesion progression but, in many patients, secondary factors, such as smoking and immune response, are clearly important. However, the mechanisms involved in the interaction between HPV and host factors are poorly understood. 



Classifying chalk microtextures: Sedimentary versus diagenetic origin (Cenomanian-Santonian, Paris Basin, France)

International audienceMicrotexture describes the type of particles and their arrangement in matrix samples at scanning electron microscopy scale. Although a microtexture classification exists for micritic limestone, it cannot be directly applied to chalk. This study therefore proposes a classification of chalk microtextures and discusses the origin of microtexture variability. Chalk was sampled at thirteen spatio-temporal locations along the coastline of northern France (Cenomanian-Santonian). Four criteria are defined to describe, characterize and determine chalk matrix microtexture: (i) mineralogical content; (ii) biogenic fraction; (iii) micritic fraction; and (iv) cement fraction. From these criteria, two major groups are defined: Pure Chalk Microtexture Group, with seven classes, and Impure Chalk Microtexture Group, divided into two subgroups: Argillaceous Microtexture with four classes and Siliceous Microtexture with two classes. Microtexture variability is related both to initial sedimentation and to diagenesis. Sedimentological conditions (for example, climate and distance from shore) affect chalk composition (carbonate content and type of insoluble particles), thus influencing microtexture. Changes in Pure Chalk Microtexture are the result of increasing diagenetic intensity. This classification can also be used to characterize the microtexture of subsurface chalk reservoirs. Reservoir quality depends on the petrophysical and mechanical properties of reservoir rocks, which can be better understood by exploring their sedimentary and diagenetic history, revealed by the study of chalk microtexture variability
