Dermatoglyphic patterns and Its variations in South Indian Adults

BACKGROUND; Dermatoglyphics encompasses the science related to the study of all the integumentary features such as skin configurations on the fingers, palms, toes and soles. Fingerprints are the most authentic form of evidence which is distinctive and perpetual. This is an Observational descriptive study involving the • Fingerprint and palmar prints of 200 medical students. • Fingerprint and palmar prints of 50 patients with diabetes mellitus. RESULTS: In the medical students, the percentage of loops was 60.5%, whorls were 30.35%, arches were 5.5%, and composite was 3.65%. Dermatoglyphics in male medical students: In the male medical students, the percentage of loops was 60.50%, whorls were 30.80%, arches were 5.30% and composite was 3.40% in both right and left hands. The total ridge count of males was 13077 ridges of which 6512 ridges were present in right hand (49.79%) and 6565 ridges were present in the left hand (50.20%). The a-b ridge count in males was 6801 ridges (49.25%). Among the 6801 ridges, 3428 ridges (50.40%) were present in the right hand and 3373 ridges (49.59%) were present in the left hand. The range of the atd angle was between 30° to 50°. Dermatoglyphics in female medical students: In the female medical students, the most frequently distributed fingertip pattern was loops (60.5%) followed by the whorls (29.9%), arches (5.7%) and composites (3.9%). The female subjects had a total of 11184 ridges. Among those ridges 5588 ridges were present in the right hand (49.96%) and 5596 ridges were present in the left hand (50.03%). The number of a-b ridges present in females was 7007 ridges with 50.74%. Of the 7007 ridges, 3480 ridges (49.66%) were present in the right hand and 3527 ridges (50.33%) were present in the left hand. The range of the atd angle was found to be between 30° and 50°. Sub types of dermal patterns: The total number of loops present was 1210 (60.5%). Of this ulnar loops were 1177 (58.85%) and radial loops were 33 (1.65%). 110 digital prints had arches. They constituted 5.5% of the total fingerprint pattern. The number of simple arch was 75 and tented arch was 35. The total number of composites was in 73 digital prints. The percentage of double loop was 1.5%, central pocket loop was 1%, lateral pocket loop was 0.16% and accidental loop was 0.06%. Dermatoglyphics of diabetes subjects: The percentage of whorls was 44.6%, loops 39.4%, arch 11.6% and composites 4.4%. Dermatoglyphics of male diabetics: In the male diabetics, the total number of whorls observed in the fingertips was 108, loops in 104 digital prints, arch in 24 digital prints and composites in 14 fingertips and their percentages were 43.2%, 41.6%, 9.6% and 5.6% respectively. Among the 2870 total finger ridges, (51.25%) of the male diabetes subjects, 1387 ridges (48.32%) were present in the right hand and 1493 ridges (52.02%) were present in the left hand. The number of a-b ridges was 1563 in number (50.61%). Dermatoglyphics of female diabetics: In the female diabetics, the whorl configuration was the predominant pattern in female diabetes subjects (46%). The next common pattern was the loop (37.2%) followed by arch (13.6) and composite (3.2%). The total finger ridge count of female diabetes patients was 2790 ridges (49.82%). There were 1470 ridges (52.68%) in the right hand and 1320 ridges (47.31%) in the left hand. The a- b ridge count in female diabetes patients was 1525 ridges (49.38%). The range of the atd angle in diabetes patients existed between 34° and 52°. In case of medical students, the total finger ridge counts in males, the a-b ridge count in females and the atd angle of females were statistically significant. In case of diabetics, atd angle in females was statistically significant and the total finger ridge counts and a-b ridge count were statistically insignificant. CONCLUSION: The observations of the present study were compared with the studies done previously. Many differences were encountered and they were attributed to the geographical and genetic factors

Dermatoglyphics in the south Wales coalfield: an analysis of genetic variation

In Chapter I, the subject of dermatoglyphics was introduced, and the aims of the present study outlined: to establish the range of local variation of various dermatoglyphic traits in the South Wales Coalfield and surrounding areas. Chapter II described the area studied in more detail, paying, attention to its physical geography and historical demography. In Chapter III, the sample itself was introduced, problems and methods of sampling touched upon and procedures for the analysis and interpretation of dermatographic prints presented, mentioning problems of classification and the current ideas on the mode of inheritance of the various traits. Chapter IV dealt with the analysis of the data collected. The distribution of the data sets v/as first described using univariate procedures, and then the inter-relationships between the sub- populations created investigated, using multivariate procedures, in particular the Generalised Distance statistic of Aahalanobis (D(^2)). The findings of the statistical analysis were discussed in Chapter V, and placed in the context of other investigations of dermatoplyphic variation and previous studies of genetic variation in Wales. An attempt was made to account for the pattern of local hetoroneneity disclosed by the study and the degree of care which should be exercised in the delineation of local populations in any study of Genetic relationships also emphasised

Heterogeneity of research results: New perspectives on psychological science

Replicability of research findings is a key issue in psychology, and has been the subject of considerable discussion by researchers. Replication is crucial to scientific principles, and underpins the consistency and verifiability of findings on which the foundation of scientific theories are built. Consistency of effects can be assessed through the perspective of heterogeneity, which indicates whether multiple research results into the same phenomenon are underpinned by the same true effect size. We use this perspective here to address concerns regarding replicability, and explore the application of heterogeneity in novel ways. This PhD project therefore aimed to: i) examine the heterogeneity of empirical findings in psychology; ii) consider the impact of biases in the research process on estimations of heterogeneity; iii) determine the strongest effects in psychology and their heterogeneity, and; iv) apply the perspective of heterogeneity to an existing psychological debate, the origin of psychological sex differences. In our first study, a re-analysis of 150 meta-analyses from cognitive, organisational, and social psychology was used to provide estimates of typical levels heterogeneity in psychology. This was compared to heterogeneity levels found across 57 multiple close replications. Our first study showed that low heterogeneity is achievable in psychology, but that typically heterogeneity estimates are high. Our next study used computer simulations to show that these levels of observed heterogeneity cannot be due to bias from questionable research practices or publication bias. In study 2, we showed the importance of including heterogeneity alongside effect size when interpreting an effect, and illustrated that even the largest mean effects in psychology might not be consistent in direction under conditions of high heterogeneity. Finally, in study 3 we showed that heterogeneity could provide an informative new perspective to the arguments regarding the origin of psychological sex differences. We explored several possible factors that could underlie heterogeneity in research findings, and suggest that unreliable forms of measurement and low quality of metaanalyses could provide promising avenues for further investigation in this regard. Overall, this thesis has provided an overview of the application of heterogeneity to provide a new perspective on psychological research

Annual Report of the University, 1979-1980, Volumes 1-5

Athletics at the University of New Mexico sunk to the lowest of depths in 1979-80, but the turbulent year will also be remembered as the renaissance a rebirth\u27 for the department. Scandal of national magnitude struck the trumpeted Lobo basketball program from all angles. First the NCAA handed down several accusations, followed shortly by an FBI investigation into the altering of player transcripts. Head Coach Norm Ellenberger was terminated and his assistant Manny Goldstein resigned under pressure. Ellenberger is scheduled to go before federal court June 16 on charges of mail fraud, wire fraud and interstate racketeering. UNM attorney Peter Johnstone has compiled an 800-page response to the 92 violations handed down by the NCAA infractions committee and UNM officials are scheduled to meet with the committee in Chicago in July.\u2
