The ability to advance puberty in broodstock that have a long generation interval and mature at large size is a highly valuable tool in contemporary aquaculture enterprise. Juvenile male and female wreckfish 'hāpuku' (Polyprion oxygeneios), a candidate for commercialization in aquaculture, were subjected to treatment for 8 weeks with two implants, one containing steroid (blank; estradiol-17β, E2; 11-ketotestosterone, KT; 17 α -methyltestosterone, MT), the other peptide (blank; gonadotropin-releasing hormone analog, GnRHa; kisspeptin, Kiss2-12)...

The estimation of Holstein heifer body weight (BW) from heart girth measurements is needed, as many farms do not have animal scales to make the management decisions that require BW. The correlation between heart girth and BW is known to vary with differing animal conformation. The previous equation to correlate the 2 measures for Holstein dairy heifers was done 25 yr ago. Data were derived from 6 US experiment stations that are part of Regional Research Project NC-2042: Management Systems to Improve the Economic and Environmental Sustainability of Dairy Enterprises...

In Europe, employers of all private and public enterprises have a legal obligation to protect their employers by all the different types of workplace hazards to the safety and health of workers. The most important methods developed for the work-related stress risk assessment are based on the Cox's research commissioned by European Agency for Safety and Health at Work (EU-OSHA) and are the Management Standard HSE for work-related stress in United Kingdom, the START method in Germany, the Screening, Observation, Analysis, Expertise (SOBANE) in Belgium, and the National Institute for Prevention and Safety at Work (INAIL-ISPESL) model in Italy, the latter based on the British Management Standard...

Hexabromocyclododecane (HBCD) is used as a flame retardant with extensive industrial applications, which is mainly produced at facilities on the coast of China. Radially distributed soil samples and equidistant paired water and sediment samples were taken around one of the biggest HBCD production enterprises to reflect its environmental behavior via air deposition and wastewater discharge of HBCD diastereoisomers (α-, β- and γ-HBCD). Worldwide high concentrations of HBCD (11,700ng/g in the soil, 5080ng/L in the water and 6740ng/g in the sediment) were detected in these environmental samples...

This article studies the effects of incorporating the interdependence among London small business defaults into a risk analysis framework using the data just before the financial crisis. We propose an extension from standard scoring models to take into account the spatial dimensions and the demographic characteristics of small and medium-sized enterprises (SMEs), such as legal form, industry sector, and number of employees. We estimate spatial probit models using different distance matrices based only on the spatial location or on an interaction between spatial locations and demographic characteristics...

Existing studies on the evaluation of CO2 emissions due to electricity consumption in China are inaccurate and incomplete. This study uses a network approach to calculate CO2 emissions of purchased electricity in Chinese provinces. The CO2 emission factors of purchased electricity range from 265 g/kWh in Sichuan to 947 g/kWh in Inner Mongolia. We find that emission factors of purchased electricity in many provinces are quite different from the emission factors of electricity generation. This indicates the importance of the network approach in accurately reflecting embodied emissions...

PURPOSE: Incompletely occluded aneurysms after coil embolization are subject to recanalization but occasionally progress to a totally occluded state. Deployed stents may actually promote thrombosis of coiled aneurysms. We evaluated outcomes of small aneurysms (<10 mm) wherein saccular filling with contrast medium was evident after stent-assisted coiling, assessing factors implicated in subsequent progressive occlusion. METHODS: Between September 2012 and June 2016, a total of 463 intracranial aneurysms were treated by stent-assisted coil embolization...

Academic health centers (AHCs) are the nation's primary resource for healthcare discovery, innovation, and training. US healthcare revenue growth has declined sharply since 2009, and is forecast to remain well below historic levels for the foreseeable future. As the cost of education and research at nearly all AHCs is heavily subsidized through large transfers from clinical care margins, our institutions face a mounting crisis. Choices centering on how to increase the cost-effectiveness of the AHC enterprise require unprecedented levels of alignment to preserve an environment that nurtures creativity...

INTRODUCTION: Cisgender and transgender woman sex workers (CWSWs and TWSWs, respectively) are key populations in Malaysia with higher HIV-prevalence than that of the general population. Given the impact economic instability can have on HIV transmission in these populations, novel HIV prevention interventions that reduce poverty may reduce HIV incidence and improve linkage and retention to care for those already living with HIV. We examine the feasibility of a microfinance-based HIV prevention intervention among CWSW and TWSWs in Greater Kuala Lumpur, Malaysia...

Starting in 1910, the "Flexner Revolution" in medical education catalyzed the transformation of the US medical education enterprise from a proprietary medical school dominated system into a university-based medical school system. In the 21st century, what we refer to as the "Second Flexner Century" shifts focus from the education of medical students to the education of the general population in the "4 health literacies." Compared with the remarkable success of the first Flexner Revolution, retrofitting medical science education into the US general population today, starting with K-12 students, is a more daunting task...

BACKGROUND: There is an emergent and intensive dialogue in the United States with regard to the accessibility, reproducibility, and rigor of health research. This discussion is also closely aligned with the need to identify sustainable ways to expand the national research enterprise and to generate actionable results that can be applied to improve the nation's health. The principles and practices of Open Science offer a promising path to address both goals by facilitating (1) increased transparency of data and methods, which promotes research reproducibility and rigor; and (2) cumulative efficiencies wherein research tools and the output of research are combined to accelerate the delivery of new knowledge in proximal domains, thereby resulting in greater productivity and a reduction in redundant research investments...

The goal of this project was to protect children while parents work in agriculture by improving off-farm services for children of migrant and seasonal farm workers. Large agricultural enterprises have policies forbidding children in the worksite. At the same time, their employees, who are trying to generate income, seek as many work hours as possible but often lack viable options for childcare services. As employers strive to increase their labor pool, and workers seek off-farm child care, there is mutual interest in improving access to child care services in agricultural regions dependent on large numbers of full-time and seasonal workers...

Practitioners in health sciences education and assessment regularly use a range of psychometric techniques to analyse data, evaluate models, and make crucial progression decisions regarding student learning. However, a recent editorial entitled "Is Psychometrics Science" highlighted some core epistemological and practical problems in psychometrics, and brought its legitimacy into question. This paper attempts to address these issues by applying some key ideas from history and philosophy of science (HPS) discourse...

Protein heterologous production offers viable opportunities to tailor laccase properties to specific industrial needs. The high redox potential laccase POXA1b from Pleurotus ostreatus was chosen as case study of marketable enzyme, due to its desirable properties in terms of activity/stability profile, and already assessed applicability. POXA1b was heterologously produced in Pichia pastoris by investigating the effect of inducible and constitutive expression systems on both the yield and the cost of its production...
