Terror management theory: A theoretical perspective on orgination, maintenance, and research

Research suggests that humans engage in several worldview defense mechanisms to shield against the terror associated with an awareness of mortality (Greenberg, Pyszczynski, & Solomon, 1986). To mitigate anxiety, people strongly adhere to their cultural worldviews that allow them to boost their self-esteem. This self-esteem fosters a sense of immortality because the world is considered a \u27just place that will not harm someone that is living in adherence to cultural guidelines (Rosenblatt, Greenberg, Solomon, Pyszczynski, & Lyon, 1989). This paper provides a theoretical background for Terror Management Theory including its philosophical origination, the primary tenets of the theory, and the experimental methods used to manipulate death awareness

The relationship of religiosity to psychopathy: the predictive ability of religious orientation for stress and depression in college undergraduates

Evidence supports that different levels of religiosity are related to mental health outcomes. This study examines the relationship between religiosity and measures of psychological maladjustment. The current study compared participants\u27 scores on several measures of religiosity with scores on Locus of Control, Depression, Anxiety, Stress, and Obsessive-Compulsive tendencies. Multiple regressions analyses were conducted suggesting that Indiscriminate Proreligiousness, a measure of overall religiosity, was found to be negatively correlated with stress. Highly religious people were found to have more of an intrinsic religious orientation than either extrinsic or quest orientation

Exact reconstruction analysis/synthesis filter banks with time-varying filters

This paper examines some of the analysis/synthesis issues associated with FIR time-varying filter banks where the filter bank coefficients are allowed to change in response to the input signal. Several issues are identified as being important in order to realize performance gains from time-varying filter banks in image coding applications. These issues relate to the behavior of the filters as transition from one set of filter banks to another occurs. Lattice structure formulations for the time varying filter bank problem are introduced and discussed in terms of their properties and transition characteristics

Mitochondrial junction region as genotyping marker for cyclospora cayetanensis

© 2019, Centers for Disease Control and Prevention (CDC). All rights reserved. Cyclosporiasis is an infection caused by Cyclospora cayetanensis, which is acquired by consumption of contaminated fresh food or water. In the United States, cases of cyclosporiasis are often associated with foodborne outbreaks linked to imported fresh produce or travel to disease-endemic countries. Epidemiologic investigation has been the primary method for linking outbreak cases. A molecular typing marker that can identify genetically related samples would be helpful in tracking outbreaks. We evaluated the mitochondrial junction region as a potential genotyping marker. We tested stool samples from 134 laboratory-confirmed cases in the United States by using PCR and Sanger sequencing. All but 2 samples were successfully typed and divided into 14 sequence types. Typing results were identical among samples within each epidemiologically defined case cluster for 7 of 10 clusters. These findings suggest that this marker can distinguish between distinct case clusters and might be helpful during cyclosporiasis outbreak investigation

Comparison of the Host Ranges and Antigenicity of Cryptosporidium parvum and Cryptosporidium wrairi from Guinea Pigs

Oocysts of a Cryptosporidium isolate from guinea pigs were not infectious for adult mice, but were infectious for two of three newborn calves and for suckling mice. However, oocysts isolated from calves or mice infected with guinea pig Cryptosporidium were not infectious for guinea pigs. Four isolates of C. parvum from calves were incapable of infecting weanling guinea pigs. Microscopic examination of tissue from the colon and cecum of suckling guinea pigs inoculated with C. parvum revealed sparse infection of some pups. These host range studies and previously described differences in 125 I-labeled oocyst surface protein profiles between Cryptosporidium sp. from guinea pigs and C. parvum suggest they are distinct species. We propose the name Cryptosporidium wrairi be retained. Studies with monoclonal antibodies indicate that C. wrairi and C. parvum are antigenically related.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75184/1/j.1550-7408.1992.tb01471.x.pd

Differentiating human from animal isolates of Cryptosporidium parvum.

We analyzed 92 Cryptosporidium parvum isolates from humans and animals by a polymerase chain reaction/restriction fragment length polymorphism method based on the thrombospondin-related anonymous protein 2 gene sequence. Used as a molecular marker, this method can differentiate between the two genotypes of C. parvum and elucidate the transmission of infection to humans

Genetic polymorphism among Cryptosporidium parvum isolates: evidence of two distinct human transmission cycles.

We report the results of molecular analysis of 39 isolates of Cryptosporidium parvum from human and bovine sources in nine human outbreaks and from bovine sources from a wide geographic distribution. All 39 isolates could be divided into either of two genotypes, on the basis of genetic polymorphism observed at the thrombospondin-related adhesion protein (TRAP-C2) locus. Genotype 1 was observed only in isolates from humans. Genotype 2, however, was seen in calf isolates and in isolates from a subset of human patients who reported direct exposure to infected cattle or consumed items thought to be contaminated with cattle faces. Furthermore, experimental infection studies showed that genotype 2 isolates were infective to mice or calves under routine laboratory conditions, whereas genotype 1 isolates were not. These results support the occurrence of two distinct transmission cycles of C. parvum in humans
