Gunshot missile caliber and type estimation using superposition method by exit gunshot cranial vault fracture

A case of missile group identification by comparative examination using the image superposition method is presented. Identification was carried out using a skeletonized body vault exit gunshot fracture. The exit gunshot buttonhole fracture shape and dimensions reflected the bullet caliber and its flank profile. The entrance injury located on the anterior arch of the first cervical vertebra and the basilar part of the occipital bone, in this case, had no identification significance.

Complete Dislocation

✓ A case is presented in which the patient sustained a complete dislocation of the odontoid process in front of the anterior arch of the first cervical vertebra. There was no fracture of the arch of C-1 vertebra. The patient was treated successfully by transoral excision of the odontoid process and the anterior arch of C-1. Twenty days later the patient's spine was stabilized posteriorly at C-1 through C-3 with wire and methylmethacrylate.

Abstract. We present a case of spontaneous meningioma in a female pig-tailed macaque (Macaca nemestrina) more than 24 years old. Clinically, the monkey displayed slow, weak, and insecure movements and poor vision. A tumorous mass was present at the floor of the cranial vault extending from the optic chiasm towards the foramen magnum. It compressed adjacent parts of the brain, infiltrated the sphenoidal and occipital bone, and showed transcranial expansion into the pharyngeal area. Histologically, the tumor was consistent with a meningioma displaying mostly meningothelial and some microcystic components. Since only six cases of meningiomas in nonhuman primates have been reported so far and only two of these meningiomas have been described in detail, the findings of each case should be reported to expand the knowledge base of this type of tumor. In addition, this is the first description of a meningioma in pig-tailed macaques.

Substantial Effort

Summary: A social identity model of effort exertion in groups is presented. In contrast to most traditional research on productivity and performance motivation, the model is assumed to apply to groups of all sizes and nature, and to all membership contingent norms that specify group behaviors and goals. It is proposed that group identification renders behavior group-normative and encourages people to behave in line with group norms. The effect should be strengthened among people who most need consensual identity validation from fellow members, and in intergroup contexts where there is inescapable identity threat from an outgroup. Together these processes should encourage people to exert substantial effort on behalf of their group.

Identification Processes

Abstract. This study explored how group identification, avatar similarity identification, and social presence mediated the effect of character type (avatars or agents) and social identity cues (presence or absence of avatars wearing participants’ school colors) on game enjoyment. Playing with teammate avatars increased enjoyment indirectly by enhancing group identification. In addition, the presence of social identity cues increased enjoyment indirectly by augmenting identification with one’s avatar. Unexpectedly, playing in multiplayer mode in the presence of social identity cues decreased enjoyment, whereas playing in multiplayer mode in the absence of social identity cues increased enjoyment. Social presence was not a reliable mediator. The findings supported media enjoyment and social identity theories, and highlighted how virtual character type and identification processes influence enjoyment.
