Evolution of Craniofacial Architecture and Lateralization in Perissodini Scale-Eaters

To understand the evolution of craniofacial asymmetry within the Perissodini tribe, a group of scale-eating fish found in Lake Tanganyika, we performed shape analysis on their craniofacial architecture, and applied a simple lever model to measure asymmetry in lower-jaw mechanics. We found that craniofacial asymmetries were the consequence of sided differences in size and shape of craniofacial elements, and that sided differences in shape predict the lateralization of force and speed of the lower jaw in derived species. Quantitative Trait Locus analysis in Lake Malawi cichlids identified a single locus of major effect for jaw laterality, the first genetic marker for handedness in an antisymmetric trait. Studying the evolution of laterality in Perissodus and ultimately identifying the genetic factors that contribute to the asymmetric development of skeletal structures will shed light on the evolutionary and clinical consequences of vertebrate laterality

Barriers to women in the UK construction industry

Purpose – This paper aims to identify the main barriers that lead to the under-representation of women in the UK construction industry. The study, funded by ConstructionSkills, seeks to explore the issues that women face and investigate the potential positive impact that continuous professional development (CPD) may have upon improving the retention and career progression of women. Design/methodology/approach – The study uses an open-ended grounded theory (GT) approach, including 231 semi-structured questionnaires and nine focus groups with women from a range of professional occupations. All the findings were analysed using keyword analysis to identify the top two barriers that women face, alongside a series of cross-cutting key themes and issues. Findings – The findings reveal that male-dominated organisational cultures and inflexible working practices are the main barriers to women in the UK construction industry, irrespective of job role or profession. This paper concludes by arguing for a sea-change in the expansion of CPD opportunities for women in managerial, confidence and communication based skills, with accompanying networking and support systems to facilitate the retention and advancement of women in the industry sector. Research limitations/implications – Due to the research approach, the data are not generalisable. Therefore, researchers are advised to research and test the findings with a larger group. Researchers are also recommended to investigate the impact of expanded CPD opportunities for both men and women. Originality/value – The paper puts forward a business case for the advancement of specific CPD training for women, to facilitate the expansion of equality and diversity in the workforce in the UK construction industry

A Comparative Study of the Hardening Effects of Various Fixatives, Dehydrating, Clearing, and Embedding Agents

One of the problems commonly encountered in the preparation of tissue for histological studies is the tendency for it to become excessively hardened before sectioning with a rotary microtome. The purpose of the investigation was to discover by as objective a means as possible not only the hardening effects of various agents on tissues, but also the influence of the time element. The approach to this problem has been to test the hardness of the tissue with a standard penetration needle after each step in the various techniques used

Diuron From Maui Sugarcane Field Runoff is Potentially Harmful to Local Coral Reefs

In a grassroots effort to identify stressors influencing the health of Maui’s coral reefs, samples for the pre- and post-emergent herbicide, Diuron, were taken in July–August 2013, prior to, during, and after the passage of Tropical Storm Flossie on the south central coast of Maui, Hawaii. Diuron is routinely used on sugarcane fields adjacent to Hawaiian coastal waters and is a component of the anti-fouling paint used on small boats. It inhibits photosynthesis of terrestrial plants at concentrations as low as 0.1 parts per billion and can be lethal to endosymbiotic dinoflagellates in corals at concentrations less than 3 parts per billion, a concentration measured in runoff samples taken during this study. While Diuron was not detected in samples taken beyond the coastal outfall or in an adjacent boat basin, this effort provides evidence that a detectable influx of Diuron into Maui’s coastal waters can result from a single rain event. Further, this study will inform efforts to support a ban on the use of Diuron in the wet season and guide monitoring efforts to better understand the effects of Diuron in coastal areas

The Attitudes and Beliefs About Manual Therapy Held By Patients Experiencing Low Back Pain: A Scoping Review

Background Manual therapy (MT) is commonly used to manage low back pain (LBP) and involves a complex interaction between the practitioner and patient. Attitudes and beliefs about MT may play a role in the outcomes seen in patients experiencing LBP. However, knowledge of patients’ attitudes and beliefs regarding MT is currently limited. Objective To map the existing published literature on the attitudes and beliefs about MT in patients experiencing LBP. Design Scoping Review. Method A systematic search was conducted across the PubMed, CINAHL, PsycINFO and Scopus databases. Study selection involved screening 1) title and abstracts and 2) full text articles. Data was analyzed to provide a descriptive summary of the studies and to develop themes of patients’ attitudes and beliefs about MT. Results A total of 767 records were identified from the initial search strategy. Following study selection, 14 articles were included for data analysis. Five themes related to patients’ attitudes and beliefs about MT were developed from the existing literature. Attitudes and beliefs about MT are explored and measured inconsistently with only one validated tool available. Conclusion MT is believed to be a preferential and effective treatment with accepted levels of post-treatment soreness. This review indicated that patients believe that MT has a biomedical mechanism of action and is suitable for biomedical causes of LBP. Several gaps in the literature are present that require further investigation

The Effect of Trait and State Disgust on Fear of God and Sin

There is a growing literature suggesting disgust plays a major role in religiosity. However, the relationships between specific domains of disgust sensitivity and general religious fundamentalism or religious scrupulosity remains unknown and a lack of experimental data prevents the drawing of causal inferences about the potential effects of disgust on religiosity. Two studies are reported that examined the relationship between specific types of disgust sensitivity (i.e., pathogen, sexual, and moral disgust) and specific religious beliefs (i.e., fear of sin and fear of God). In the first study it was found that sexual disgust and pathogen disgust were significantly correlated with fear of sin and fear of God, respectively. In the second study the experimental induction of disgust led to greater fear of sin but not to the fear of God. These findings suggest that pathogen and sexual disgust sensitivities may serve as effective mechanisms for inflated scrupulosity. Taken together the outcomes from both studies converge on a greater understanding of the 'Human Behavioral Immune System' model that can account for social behavior with the evolution of adaptive benefit and perhaps more importantly highlights the possible drivers of specific religious behavior
