[Origin identification of Gardeniae Fructus based on hyperspectral imaging technology].

In order to realize rapid and non-destructive identification of the origin of Gardeniae Fructus, a technical method based on hyperspectral imaging technology was established in this study. Spectral information of Gardeniae Fructus samples from eight production origins was acquired from visible NIR(410-990 nm, VNIR) and short wavelength NIR(950-2 500 nm, SWIR) bands based on hyperspectral imaging techniques. The average spectral reflectance within the region of interest was extracted and calculated using the ENVI 5.3 software, resulting in 1 600 sample data. The visible short wavelength infrared band(fused bands) spectral data covering the range 410-2 500 nm were obtained after combining the spectral data of VNIR and SWIR. Data were de-noised by five common preprocessing methods, including multivariate scatter correction, Savitzky-Golay smoothing, standard normal variate, first derivative(FD), and second derivative from VNIR, SWIR, and fused bands(VNIR+SWIR). Partial least squares discriminant analysis, linear support vector classification(LinearSVC), and random forest were used to establish the model for origin identification of Gardeniae Fructus. The results indicated that the identification model of Gardeniae Fructus origin established after FD pretreatment of the spectral data in the fused bands could yield good results. According to the confusion matrix evaluation results, the model prediction set using LinearSVC reached 100% accuracy, so the optimum identification model of Gardeniae Fructus origin was determined as fusion bands-FD-LinearSVC. Therefore, the hyperspectral imaging technology can achieve rapid, nondestructive, and accurate identification of Gardeniae Fructus samples of different origins, which provides a technical reference for the differential detection of Gardeniae Fructus and other Chinese medicines.

Variation in Major Depressive Disorder Onset by Place of Origin Among U.S. Latinos.

Using a nationally representative sample of 2514 U.S. Latinos, this study examined the extent to which major depressive disorder (MDD) onset differs by place of origin and the factors associated with it. The Kaplan-Meier method estimated the survival and hazard functions for MDD onset by place of origin, and Cox proportional hazards models identified its associative factors. Approximately 13% of the sample had experienced MDD in their lifetimes. Cuban respondents showed the highest survival function, while Puerto Ricans showed the lowest. With the entire sample, the smoothed hazard function showed that the risk of MDD onset peaked in the late 20s and early 80s. Puerto Rican respondents showed the highest risk of MDD during their 20s and 30s, whereas Cuban respondents showed a relatively stable pattern over time. The results from the Cox proportional hazards model indicated that age, sex, and marital status were significantly related to MDD onset (p < .05). In addition, the effect of U.S.-born status on MDD onset was greater among Mexican respondents than among Puerto Ricans. Findings from the present study demonstrate that different Latino subgroups experience different and unique patterns of MDD onset over time. Future research should account for the role of immigration status in examining MDD onset.

Discrimination and mental health among Latinos: variation by place of origin.

The US Latino population experiences high rates of discrimination, which may contribute to psychiatric disorders. Yet, little is known about the distinctions in this relationship for Latino subgroups. Using data from the National Latino and Asian American study, we examined the association between discrimination and mental health for 2503 Latinos. Logistic regression analyses were used to examine variation in the relationship by place of origin (Cuba, Puerto Rico, Mexico, or Other). Results suggest that perceived discrimination increased the probability of having a psychiatric disorder. The effect of discrimination on having a psychiatric disorder was greater for Mexicans than Puerto Ricans. The findings of this study suggest that variation exists in the relationship between discrimination and mental health by origin. Implications for practice include increasing awareness of place of origin, in addition to discrimination, as a risk factor for mental illness. Future research should examine this relationship longitudinally and consider immigration status.

Analysis on Changes and Influencing Factors of the Intestinal Microbiota of Alpine Musk Deer between the Place of Origin and Migration.

In China, the population of wild musk deer, belonging to the family Moschidae, has drastically decreased in recent years owing to human activities and environmental changes. During the 1990s, artificial breeding of Alpine musk deer was conducted in Xinglong Mountain, Gansu Province, China, and their ex situ conservation was explored for over a decade. Ex situ protection is beneficial for expanding the population of animals and maintaining their genetic diversity; however, it can also induce metabolic diseases and parasitic infections and reduce reproductive capacity. The gut microbiota of animals has a considerable impact on host energy metabolism and immune regulation, thereby playing a crucial role in the overall health and reproductive success of the host. In this study, by comparing the differences in the intestinal microbiome of the musk deer according to their place of origin and migration, the changes in their gut microbiota and the influencing factors were explored to provide a theoretical basis for monitoring the health status of the musk deer. We used 16S rRNA high-throughput sequencing technology to analyze the structure and diversity of the gut microbiota of Alpine musk deer in Gansu (G, place of origin) and Sichuan (S, place of migration). The results showed that the dominant bacteria and genera in the intestinal microbiome of captive musk deer were similar in the places of origin and migration, but significant differences were observed in their relative abundance (p < 0.05). Regarding Firmicutes and Actinobacteria, which are related to plant cellulose digestion, the relative abundance in group G was higher than that in group S; regarding Proteobacteria and Verrucomicrobia, which are related to fat and starch intake, the relative abundance in group S was higher than that in group G; the relative abundance of Bacillus and Clostridium sensu stricto, which are related to fiber digestibility, was higher in group G than in group S; the relative abundance of conditional pathogens Acinetobacter and Escherichia-Shigella was higher in group S than in group G. The results of α and ß diversity analysis also showed significant differences between the two groups (p < 0.05). The ACE and Shannon indices of musk deer in group G were considerably higher than those in group S, and the Simpson index of musk deer in group S was greater than that in group G, indicating that the abundance and diversity of intestinal microbiome were higher in musk deer of Gansu than those of Sichuan. Comparison of the changes in the intestinal microbiome of the musk deer according to the place of origin and migration showed that the plant cellulose content in the food of the musk deer, the fat content in the concentrated feed, and changes in the feeding environment have an impact on the intestinal microbiome. Effective monitoring of the health and immunity of the musk deer is crucial for ensuring their overall health, which in turn will aid in formulating a scientific and reasonable management plan for their conservation.

Relationship Between Childhood Left-Behind Experience and Quality of Life Among Chinese University Freshmen: Place of Origin Matters.

Background: Childhood left-behind experience (LBE) has a long-term detrimental effect on the mental health of Chinese University students, but it remains unclear whether childhood LBE negatively impacts the quality of life (QOL) of University students and whether the LBE-QOL association differs between students of rural origin and students of urban origin. This study examined the LBE-QOL relationship and the interactive effect between LBE and place of origin on QOL among Chinese University freshmen. Methods: By using a two-stage random cluster sampling approach, a total of 5,033 freshmen were recruited from two comprehensive universities. The students completed an online, self-administered questionnaire that included sociodemographic variables, a 2-week physical morbidity assessment, and assessments of depressive symptoms, academic stress, and QOL. The Chinese six-item QOL scale was used to assess QOL. Multiple linear regression was used to test the independent LBE-QOL association and the interaction between LBE and place of origin. Results: Students with childhood LBE had significantly lower QOL scores than those without LBE (60.1 ± 13.1 vs. 64.3 ± 11.7, p < 0.001). After adjusting for the potential confounding effects of other sociodemographic variables, 2-week physical morbidity, depressive symptoms, and academic stress, childhood LBE was significantly associated with a lower QOL score (ß: -3.022, p < 0.001) and the LBE-place of origin interaction was still significantly associated with the QOL score (ß: -2.413, p < 0.001). Overall, compared to non-LBE, LBE was associated with a QOL score decrease of 5.93 among freshmen of urban origin and of 3.01 among freshmen of rural origin. Conclusion: In Chinese University freshmen, childhood LBE is independently associated with poor QOL, and the LBE-QOL association is greater among freshmen from urban backgrounds than among freshmen from rural backgrounds.

Meat packaging, preservation, and marketing implications: Consumer preferences in an emerging economy.

Meat is a perishable food which appears in the market in a variety of forms. Using a choice experiment survey conducted across four Chinese cities, this paper studies consumers' preferences for packaging and preservation methods and place of origin for fresh pork. Results showed that Chinese consumers preferred chilled and locally produced pork packaged in plastic. They discounted frozen and imported pork more than hot pork. Consumers believed that meat, which had been frozen or preserved over a long period, was not as fresh. Many consumers believe their own perceptions about meat preservation methods are correct when in fact they may be wrong. When scientific information about meat preservation methods was introduced, a significantly positive effect could be observed on their preferences and on the willingness-to-pay for frozen meat, chilled meat, and imported meat. This suggests that using science-based information to educate consumers can increase the economic value of pork. The implications on the marketing and trade of pork are explored.

Using Carbon, Oxygen, Strontium, and Lead Isotopes in Modern Human Teeth for Forensic Investigations: A Critical Overview Based on Data from Bulgaria.

Isotopic data obtained from human remains can provide information about an individual's origin, migration, and diet. We evaluate the usefulness of carbon, oxygen, strontium, and lead isotopes for forensic investigations by comparing data from Bulgarian teeth with data from other regions. Geo-referencing based on oxygen or strontium isotopes can be misleading due to overlap with other countries in Europe and other continents. Carbon and lead isotopes, in combination with oxygen and strontium isotopes, provide the most useful information for identification of local vs foreigner status. In particular, high-precision Pb isotopes show a distinct "Bulgarian" range; however, it is possible that individuals from other countries in Eastern Europe and/or central to western Asia could have overlapping isotopic values. Additional high-precision multi-isotope data from modern humans from different regions in the world are required to transition from speculative to more quantitative estimation of a geographical place of origin for unidentified human remains.

Creencias Irracionales en Estudiantes de Psicología de una Universidad Privada de Lima Metropolitana, según el Nivel de Estudios, Sexo y Lugar de Origen / Irrational Beliefs in Psychology Students of a Private University in Metropolitan Lima, an Analysis by Level of Studies, Sex, and Place of Origin

Resumen La presente investigación plantea que las creencias irracionales descritas por Albert Ellis son afirmaciones anti empíricas que causan un malestar emocional en quienes las poseen. Por ello se busca analizar la presencia de estas en estudiantes de psicología y su asociación con el nivel de estudios, sexo y lugar de origen. Fueron seleccionados 278 estudiantes de una universidad privada de Lima Metropolitana. Se utilizó el Registro de Opiniones de Ellis. Los resultados muestran que los estudiantes de psicología presentan la creencia 6 (se debe sentir miedo o ansiedad ante cualquier cosa desconocida o potencialmente peligrosa) de manera sumamente limitante, y las creencias 2 (uno debe ser indefectiblemente competente y casi perfecto en todo) y 8 (se necesita contar con algo más grande y fuerte que uno) de manera posiblemente limitante. Por otro lado, se encontró asociación con el nivel de estudios de las creencias 3 (ciertas personas son malas y deberían ser castigadas) y 8, donde, a mayor nivel de estudios, menos creencias. También se verifica asociación entre las creencias irracionales 1 (para un adulto es necesario tener el cariño y la aprobación de sus semejantes, familia y amigos), 3 y 10 (la felicidad aumenta con la inactividad) con sexo.

Abstract The research suggests that Albert Ellis irrational beliefs are antiempirical statements that cause emotional distress in people who possess them. In his theory A B C, argues that what we feel is not based on what happens around us, but on how we interpret that reality. Then, A would become the event that occurs, B the interpretation we make, and C the emotional and behavioral consequence. From this, Albert Ellis groups this idea generating ten final irrational beliefs and creates an instrument to measure them called Registro de Opiniones, which has 100 items, 10 for each of the beliefs. That is why I attempt to analyze the presence of irrational beliefs in psychology students and their correlation with educational level, sex and place of origin. I selected 282 university students getting their BA in psychology at a private university in Lima Metropolitana. The Albert Ellis Inventory, Registro de Opiniones, was applied after obtaining written informed consent. The hypothesis was that there is a correlation between the irrational beliefs of the students and their educational level, sex and place of origin. The results showed than psychology students that the sixth irrational belief is found in an (it should feel fear or anxiety to any unknown, uncertain or potentially dangerous thing) extremely limited way. Belief number 2 (must be unfailingly competent and almost perfect in everything I undertake) and 8 (you need to have something bigger and stronger than oneself) were found in a possibly limiting manner. Beliefs number 3 and 8 were found in a correlating manner with education level. Seeming that as higher level of education less strength of the belief. There was also an association between irrational beliefs 1 (for an adult is absolutely necessary to have the love and approval of their peers, family and friends), 3 and 10 (happiness increases with inactivity, passivity and leisure undefined) with sex. Finally, no association was found between irrational beliefs and place of origin.
