Who’s Getting a Head Start? Mesocephalic Dogs in Still Images Are Attributed More Positively Valenced Emotions Than Dogs of Other Cephalic Index Groups

Assumptions about dogs’ personality are influenced by their appearance, which may lead to differences in ownership styles and subsequent canine welfare. The influence of canine appearance on observers’ emotion attributions to dogs remains largely unexplored. This study investigated whether canine head shape is related to how both dog owners and non-dog owning adults in the U.K. attribute emotions to still images of dogs, and in the case of dog owners, to their own dogs. Attachment, respondent personality and dog trainability were assessed as potential influences on emotional attribution in owners. Overall, 2451 participant responses were received. Still images of mesocephalic dogs were attributed primary and positively valenced emotion with more strength and frequency than other groups. Mesocephalic images were also attributed negatively valenced emotions less frequently and with less strength than other groups. Apart from empathy, no significant differences were found in emotional attribution to owned dogs of different head shapes; however, human personality influenced attribution of emotions to owned dogs. The finding that some dogs are attributed emotions more readily based on their appearance alone has applied importance, given, for example, the potential for misattribution of positive emotions to dogs in negative emotional states, and potential prejudice against dogs considered in negative emotional states.

Association between Brachycephaly, Chiari Malformation, and Basilar Invagination

Background There is evidence that Chiari malformation (CM) and basilar invagination (BI) are largely due to disproportion between the content and volume of the posterior fossa. A recent study identified an increased association between brachycephaly and BI. In several types of craniosynostosis, the posterior fossa volume is smaller than normal, and this is more pronounced in coronal synostosis. The aim of this study is to evaluate the association between CM and BI. Methods The cephalic index (CI) measured on magnetic resonance imaging (MRI) from a sample of patients with craniocervical malformation was compared with that of normal subjects. Results The average CI in the craniovertebral junction malformation (CVJM) group was significantly higher in BI patients than in normal subjects. The BI patients also had the highest CI among the whole sample of patients (p = 0.009). Conclusions In this study, BI patients had the highest CI among patients with CVJM and a significantly higher CI than those in the control group. Our data confirm the association between BI and brachycephaly.

Estimation of Cephalic Index of Population of Central India

Cephalic record is otherwise called cranial list or broadness file. It's processed as the length separated by the width of the skull times by 100. Assessing varieties in cephalic records across guardians, children, and family members can uncover if hereditary qualities are passed down hereditarily. The exploration included 480 clinical understudies (296 male and 184 female understudies). Hardlika's methodology was utilized to decide the cranial record. Most of the people were Mesocephalic (cephalic record 7579.9). 43.58 percent of guys and 42.93 percent of young ladies had a mesocephalic head. Men’s had an average cephalic record of 81.24 3.66, while ladies had a regular cephalic file of 80.31 4.28. Somatometric estimations, for example, the face and cephalic records, are used in human criminological sciences. These lists utilized a human's sex and racial populace to compute their singular character. This exploration aims to give benchmark data to cephalic records and face files in the Central Indian populace, contrasting these outcomes with past research. This material will be helpful to legal specialists, anatomists, and others in related disciplines. The cephalic record (CI), in some cases called the cranial list, is the proportion of the head's maximal expansiveness to length. The motivation behind the review was to research the anthropometry of cranial qualities. The review's objective was to check out the anthropometry of cranial qualities utilizing google structures circled in the school gatherings. Experts in scientific science will see the data as advantageous, just as in clinical, medico-lawful, anthropological, and excavator settings.

Evaluation of Cephalic Index in children from the Madheshi community in Sarlahi district, Nepal

Background: Cephalic index is one of the important craniofacial parameters which is commonly used for investigating the length and breadth of the head. Cephalic Index (CI) is defined as the ratio between maximum breadth of the head and the maximum length of the head multiplied by 100. Body mass index (BMI) is a nutritional marker of the body derived from the measurement of height (in m2) and weight (in kg). Aims and Objective: To analyse the effect of BMI on the CI. Materials and Methods: This study was a cross-sectional study conducted from April 2021 to June 2021 with sample size of 200 children of age groups 5-8 years from Ramnagar Gaupalika of Sarlahi, Province 2, of Nepal. We measured the cephalic index of the children and asked a set of structured questionnaire to the guardian or parent of the children. Height and weight of the children were also measured and BMI was determined. Data analysis was completed using SPSS version 16. Results: The mean age of the participants was 6.56 years, BMI of 18.09 and cephalic index (CI) of 81.82. The mean CI in males and females were 82.05 and 81.59 respectively. Our results show significant association between BMI category and CI category (chisquare test, p-value=0.000), mode of delivery and BMI category (chisquare test, p=0.042) and significant negative correlation between BMI and CI (Pearson’s R=-0.591, p=0.037). Conclusion: The most common pattern of CI was hyperbrachycephalic in the children of low BMI whereas the pattern of CI in case of the normal BMI was the mesocephalic type. It also confirmed that the sexual dimorphism exists in both the low BMI and the normal BMI.

Cephalic Index of Adult Igbo’s in Imo State, Nigeria

Cephalic index is of great importance to anatomists, anthropologists and even to forensic scientists, in the determination of head shapes and for medicolegal cases. Cranial and post cranial measurements have typically been used to describe individuals and to compare groups. This study aims at obtaining the Cranial indices of adults Igbos in Imo state, which will help build the forensic database and in identification of age, gender, racial differences in recent and ancient humans, and in the diagnoses of certain developmental disorders of the skull, such as Craniosynostosis, Hydrocephalus, and Postural deformation. Also to correlate the results of males with that of females. One thousand, One hundred and fifty eight (1158) subjects comprising of five hundred and seventy nine (579) males and females respectively, ages 18-52 years. The measurements were done manually with the use of transparent graded ruler, measuring tapes, gliding and sliding calipers or flexible tapes. The following parameters were measured; cranial length, cranial breadth, since Cephalic Index=Cranial breadth/cranial length x 100. The mean cranial length and breadth were 172±92.89 and 160.46±27.65 respectively. The result for males Cranial Length (CL), Cranial Breadth (CB), were respectively 173.93±18.75, 161.05±17.21. The result for females Cranial Length (CL), Cranial Breadth (CB), were respectively; 171.76±30.06, 159.88±35.11. These results were used to calculate the various Cephalic Index; mean Cephalic Index (CI) was 97.26±21.55. The males Cephalic Index (CI) was100.23±26.23, and female Cephalic Index (CI) was 94.29±14.94, Analysis of the results was done using independent t-test and Pearson bivariate correlation. These tests were carried out using Statistical Package for Social Sciences (SPSS version 25). Microsoft office excel was also used during data processing. Analysis showed that there was a significant difference in the mean values of females and males. The result from this study shows that Adults in Imo state are Brachycephalic. This study is a great contribution to the forensic, anthropology, anatomical and medical database.

Comparison of aesthetic outcomes between open and endoscopically treated sagittal craniosynostosis

OBJECTIVE In the last several decades, there has been much debate regarding the ideal treatment for sagittal synostosis. The purpose of this study was to compare perioperative, anthropometric, and subjective assessments of cosmetic outcomes between open and endoscopic management of isolated sagittal synostosis. METHODS At their routine postoperative follow-up, pediatric patients with sagittal craniosynostosis were recruited to undergo digital cranial measurement and standardized photography for objective and subjective assessments of perioperative outcomes. Age-normalized z-scores for cephalic index, head circumference, euryon-euryon diameter (Eu-Eu), and glabella-opisthocranion diameter (G-Op) were calculated for each patient. Faculty surgeons, surgical trainees, nurses, and laypersons were asked to rate the normalcy of craniofacial appearances using a 5-point Likert scale. Outcomes were compared between patients treated with endoscopic correction and those treated with open repair. RESULTS A total of 50 patients were included in the study. Thirty-one had undergone open surgical correction, and 19 had undergone endoscopic treatment. Endoscopic repair involved significantly lower operative time, blood loss, transfusion rate, and hospital length of stay than those with open repair (p < 0.001). There was no significant difference between groups in terms of z-scores for head circumference (p = 0.22), cephalic index (p = 0.25), or Eu-Eu (p = 0.38). Endoscopic treatment was associated with a significantly lower G-Op (p = 0.009). Additionally, the average subjective rating of head shape was higher for endoscopic treatment when corrected for age, gender, and ethnicity (p = 0.02). CONCLUSIONS The study findings suggest that patients who are treated endoscopically may have an overall more normal appearance in skull morphology and cosmesis, although these results are limited by poor reliability.

Henryk Sienkiewicz wobec kryteriów rasowo-antropologicznych. O listach Z wystawy antropologicznej w Paryżu

[Henryk Sienkiewicz and Racial-Anthropological Criteria. On the Letters Z wystawy antropologicznej w Paryżu] This article discusses Henryk Sienkiewicz’s approach to the 19th-century “scientific racism” in his “letters” (press reportage) Z wystawy antropologicznej w Paryżu [From the Anthropological Exhibition in Paris] (1878). The paper proves that the writer’s attitude towards such anthropological criteria as the cephalic index, facial angle, skull volume, and hair shape was significantly influenced by Oscar Peschel’s work The Races of Man and Their Geographical Distribution (1876).
