AbstractThrough the analyses of the number of identified specimens (NISP), minimum number of individuals (MNI) and estimation of meat available from the animal remains unearthed from representative sites of the Chengdu Plain Type and Eastern Chongqing Type of the Shi’erqiao Culture, this paper discusses the subsistence strategy of this culture. The results show that the meat resources of the Chengdu Plain Type were mainly domesticated animals, while those of the Eastern Chongqing Type were mainly hunted animals. This paper draws the conclusion that in the early stage of human civilization, the subsistence strategies of different types of the same archaeological culture might be different, while those of different archaeological cultures might be similar; the factors influencing the subsistence strategies are mainly the natural environment, regional economic traditions, and population pressures.

Abstract Background Healthy and sustainable dietary practices offer a possible solution to competing tensions between health and environmental sustainability, particularly as global food systems transition. To encourage such dietary practices, it is imperative to understand existing dietary practices and factors influencing these dietary practices. The aim of this study was to identify multi-level factors in lived rural and urban Ugandan food environments that influence existing dietary practices among women of reproductive age (WRA). Methods A mixed methods study was conducted. Multiple correspondence analysis followed by hierarchical cluster analysis were performed on dietary data collected among a sample (n = 73) of Ugandan WRA in Kampala (urban) and Wakiso (rural) districts to elicit dietary clusters. Dietary clusters, which were labelled as dietary typologies based on environmental impact and nutrition transition considerations, were reflective of dietary practices. Following this, a smaller sample of WRA (n = 18) participated in a Photovoice exercise and in-depth interviews to identify factors in their social, physical, socio-cultural and macro-level environments influencing their enactment of the identified dietary typologies, and therefore dietary practices. Results Four dietary typologies emerged: ‘urban, low-impact, early-stage transitioners’, ‘urban, medium-impact, mid-stage transitioners’, ‘rural, low-impact, early-stage transitioners’ and ‘rural, low-impact, traditionalists’. Although experienced somewhat differently, the physical environment (access, availability and cost), social networks (parents, other family members and friends) and socio-cultural environment (dietary norms) were cross-cutting influences among both urban and rural dietary typologies. Seasonality (macro-environment) directly influenced consumption of healthier and lower environmental impact, plant-based foods among the two rural dietary typology participants, while seasonality and transportation intersected to influence consumption of healthier and lower environmental impact, plant-based foods among participants in the two urban dietary typologies. Conclusion Participants displayed a range of dietary typologies, and therefore dietary practices. Family provides an avenue through which interventions aimed at encouraging healthier and lower environmental impact dietary practices can be targeted. Home gardens, urban farming and improved transportation could address challenges in availability and access to healthier, lower environmental impact plant-based foods among urban WRA.

1. It has been suggested that 2-amino-6-(2-formyl-5-hydroxymethyl-pyrrol-l-yl)-hexanoic acid ('pyrraline') is formed as an advanced glycation end product in the Maillard reaction under physiological conditions. Antibodies were raised to caproyl-pyrraline linked to keyhole-limpet haemocyanin and were used to develop an e.l.i.s.a. and Western blotting system for the specific detection of pyrraline in samples in vivo and in vitro. 2. Human serum albumin was isolated from the serum samples of diabetic and non-diabetic subjects. Pyrraline was not detected (<1.2 pmol) in any of the samples, indicating that it was not a major advanced glycation end product in vivo. 3. BSA was incubated separately with D-glucose and a model fructosamine, N-(l-deoxy-D-fructos-l-yl)-hippuryl-lysine, under physiological conditions for 30 days. Aliquots removed from the incubations at 5 day intervals contained no detectable pyrraline, indicating that pyrraline was not an early-stage product of the Maillard reaction in vitro. 4. The model fructosamine, N>-(1-deoxy-D-fructos-l-yl)-hippuryl-lysine, was incubated at pH 7.4 and 37°C for 25 days during which it degraded to hippuryl-lysine and N>-carboxymethyl-hippuryl-lysine. Aliquots were removed at 5 day intervals and assayed for pyrraline. None was detected (<23 pmol/ml) in the course of the degradation of the fructosamine (400 nmol/ml degraded), indicating that pyrraline was not a major product of the degradation of fructosamine under physiological conditions in vitro. 5. We conclude that pyrraline is not a major intermediate or advanced glycation end product in the Maillard reaction under physiological conditions in vitro and in vivo. A previous report of immunoassay of pyrraline may have given positive results because of non-specific antibodies raised to impure hapten.

The purpose of this study was to examine the factors influencing professional judgment of Malaysian auditors. A questionnaire was used to measure the level of professional judgment and factors influencing the judgment such as gender, knowledge, position level, experience and also firm size. The multiple regression results showed that the position level and experience to be statistically significant in determining the level of professional judgment of auditors. Gender, knowledge and firm size have no significant relationship with professional judgment. As for gender, past research has shown mixed results and this study proves that there is no gender differences among Malaysian auditors in terms of their professional judgment. Even though past research has shown that knowledge has a positive relationship with professional judgment, this study finds no significant relationship between the two variables. With regard to firm size, this study finds similar results of prior study that there is no significant relationship between firm size and judgment. In terms of the practical implications, this study provides insights into significant factors that influence professional judgment of Malaysian auditors. Besides, the management of audit firms can place emphasis on establishing training to their employees especially for the junior staff. Exposing junior auditors at the early stage might improve their professional judgment when facing with complexities of assignments.
