The free recall search process introduces errors in short term memory but apparently not in long term memory
No full textHere it is reported that the free recall search process increases the error rate for short term memory (about 1% per second in data from Murdock & Okada (1970)) but not for long term memory (in data from McDermott (1996)). If the short term memory search process introduces random excitations, which would account for the search errors, the subjects should be unaware of making such errors. This is in agreement with DRM findings (Gallo, 2010) and the new finding that the error terminated distributions in Murdock (1962) are the same as those terminated by studied items
Peristaltic flow of a Newtonian fluid through a porous medium in a vertical tube under the effect of a magnetic field
No full textIn this paper, we studied the effects of heat transfer and magnetic field with peristaltic flow of a viscous incompressible Newtonian fluid through a porous medium in a vertical tube under the assumptions of long wavelength and low Reynolds number. The closed form solutions of velocity field and temperature are obtained. The influence of various pertinent parameters on the flow characteristics, the temperature and the heat transfer coefficient are discussed through graphs
Crawling Facebook for Social Network Analysis Purposes
No full textWe describe our work in the collection and analysis of massive data describing the connections between participants to online social networks. Alternative approaches to social network data collection are defined and evaluated in practice, against the popular Facebook Web site. Thanks to our ad-hoc, privacy-compliant crawlers, two large samples, comprising millions of connections, have been collected; the data is anonymous and organized as an undirected graph. We describe a set of tools that we developed to analyze specific properties of such social-network graphs, i.e., among others, degree distribution, centrality measures, scaling laws and distribution of friendship.\u
Improving Recommendation Quality by Merging Collaborative Filtering and Social Relationships
No full textMatrix Factorization techniques have been successfully applied to raise the quality of suggestions generated\ud
by Collaborative Filtering Systems (CFSs). Traditional CFSs\ud
based on Matrix Factorization operate on the ratings provided\ud
by users and have been recently extended to incorporate\ud
demographic aspects such as age and gender. In this paper we\ud
propose to merge CF techniques based on Matrix Factorization\ud
and information regarding social friendships in order to\ud
provide users with more accurate suggestions and rankings\ud
on items of their interest. The proposed approach has been\ud
evaluated on a real-life online social network; the experimental\ud
results show an improvement against existing CF approaches.\ud
A detailed comparison with related literature is also presen
Looking for the Lazy Argument Candidates
No full textThe Lazy Argument, as it is preserved in historical testimonies, is not logically conclusive. In this form, it appears to have been proposed in favor of part-time fatalism (including past time fatalism). The argument assumes that free will assumption is unacceptable from the standpoint of the logical fatalist but plausible for some of the non-universal or part-time fatalists. There are indications that the layout of argument is not genuine, but taken over from a Megarian source and later transformed. The genuine form of the argument seems to be given in different form and far closer to logical fatalism and its purpose is not to defend laziness. If the historical argument has to lead to a logically satisfactory solution, some additional assumptions and additional tuning is needed

A Brief Note on How Phenomenal Objects Relate to Objects Themselves
No full textThis brief note corrects some basic errors in Meijsing’s (2011) JCS paper on “The Whereabouts of Pictorial Space”, concerning the status of phenomenal objects in the reflexive model of perception. In particular I clarify the precise sense in which a phenomenal object relates to the object itself (the noumenal object) in visual perception
Genetic Disease Burden, Nutrition and Determinants of Tribal Health Care in Chhattisgarh State of Central-East India: A Status Paper
No full textTribal health is an important aspect of development and progress of the people. This study pertaining to genetic disease burden, nutritional status and biomedical anthropological assessment with particular reference to determinants of tribal health care has been carried out among the four tribes, namely, Bhatra, Gond, Kondh and Paraja of Orissa residing adjacent to the bordering districts of Chhattisgarh The population genetic structure of a tribe is the outcome of socio-cultural practices, bio-psychological behavior, genetic constitution, and eco-environmental conditions. Tribal communities in India, in general and of Chhattisgarh state in particular, are highly vulnerable to various genetic diseases, nutritional deficiencies and unrealistic practices and lack of access to basic health facilities. A total of 815 blood samples comprising of 166 Bhatra, 219 Gond, 254 Kondh and 176 Paraja tribes were collected randomly under aseptic conditions. The frequency of sickle cell hemoglobinopathy (3.2-22.5%), β-thalassemia trait (0.5-8.5%), and G6PD enzyme deficiency (6-16%) is very high among the tribes of Chhattisgarh. However, the prevalence of Rhesus negative blood group is very low (0-0.6%). The frequency of hereditary hemolytic anemia is also high among the tribals of Chhattisgarh. Both communicable and non-communicable diseases harbor the tribal population. The nutritional deficiencies are rampant. Tribal people are engrossed with superstitions and have faith in traditional healers who practice magico-religious rites along with indigenous herbal treatment for the common ailments. Traditional folk medicine and health culture play a significant role in shaping tribal life. These health practices differ from one tribe to another. Unless locality specific, tribe specific and need-based health care system is evolved which should be appropriate, acceptable, accessible, and affordable, the true goal of health for all cannot be achieved in India
Villar’s Nodule
No full textVillar’s Nodule or primary umbilical endometrioma is a rare condition, with an estimated incidence of 0.5 to 1% of all patients with endometrial ectopia. Several aetiological theories have been proposed for its pathogenesis with coelomic metaplasia being the favoured one and also, umbilicus may acts as a physiological scar with a predilection for endometrial tissue in the development of spontaneous umbilical endometriosis. Since endometriosis remains a diagnostic and therapeutic enigma even today, largely due to its variable presentations, we, hereby report a case of primary umbilical endometrioma due to its rarity and unusual presentation
Drinking Water Quality Deterioration in Households of Students with High Illness Absenteeism
No full textObjective: School and household lacked safe drinking water and thus school absenteeism rates were high among students with poor water quality. So we assessed fecal contamination of drinking water in households of students with high illness absenteeism and evaluate the factors for non-potability. Method: Drinking water samples (100) were collected from household water container of 50 students for fecal contamination. Results: A total of 40 (80%) family’s water was potable before use, out of which 40% became non-potable after use. Factors responsible for reduction in potability were water withdrawal without handwashing up to (56%), poor domestic hygiene (56%), dipping hands in water (55%), placing water dipper on lid (52%) and no washing of container (0%). Socio-economic condition also had impact on water potability. Conclusion: Water quality deterioration occurs by multiple factors like improper storage, unhygienic habits of water handling and circumstances. Results focused on the need for further protocols for safe and hygienic storage of water
