HiRel: Hybrid Automated Reliability Predictor (HARP) integrated reliability tool system, (version 7.0). Volume 3: HARP Graphics Oriented (GO) input user's guide

The Hybrid Automated Reliability Predictor (HARP) integrated Reliability (HiRel) tool system for reliability/availability prediction offers a toolbox of integrated reliability/availability programs that can be used to customize the user's application in a workstation or nonworkstation environment. HiRel consists of interactive graphical input/output programs and four reliability/availability modeling engines that provide analytical and simulative solutions to a wide host of highly reliable fault-tolerant system architectures and is also applicable to electronic systems in general. The tool system was designed at the outset to be compatible with most computing platforms and operating systems, and some programs have been beta tested within the aerospace community for over 8 years. This document is a user's guide for the HiRel graphical preprocessor Graphics Oriented (GO) program. GO is a graphical user interface for the HARP engine that enables the drawing of reliability/availability models on a monitor. A mouse is used to select fault tree gates or Markov graphical symbols from a menu for drawing

Expert-based development of a generic HACCP-based risk management system to prevent critical negative energy balance in dairy herds

The objective of this study was to develop a generic risk management system based on the Hazard Analysis and Critical Control Point (HACCP) principles for the prevention of critical negative energy balance (NEB) in dairy herds using an expert panel approach. In addition, we discuss the advantages and limitations of the system in terms of implementation in the individual dairy herd. For the expert panel, we invited 30 researchers and advisors with expertise in the field of dairy cow feeding and/or health management from eight European regions. They were invited to a Delphi-based set-up that included three inter-correlated questionnaires in which they were asked to suggest risk factors for critical NEB and to score these based on 'effect' and 'probability'. Finally, the experts were asked to suggest critical control points (CCPs) specified by alarm values, monitoring frequency and corrective actions related to the most relevant risk factors in an operational farm setting. A total of 12 experts (40 %) completed all three questionnaires. Of these 12 experts, seven were researchers and five were advisors and in total they represented seven out of the eight European regions addressed in the questionnaire study. When asking for suggestions on risk factors and CCPs, these were formulated as 'open questions', and the experts' suggestions were numerous and overlapping. The suggestions were merged via a process of linguistic editing in order to eliminate doublets. The editing process revealed that the experts provided a total of 34 CCPs for the 11 risk factors they scored as most important. The consensus among experts was relatively high when scoring the most important risk factors, while there were more diverse suggestions of CCPs with specification of alarm values and corrective actions. We therefore concluded that the expert panel approach only partly succeeded in developing a generic HACCP for critical NEB in dairy cows. We recommend that the output of this paper is used to inform key areas for implementation on the individual dairy farm by local farm teams including farmers and their advisors, who together can conduct herd-specific risk factor profiling, organise the ongoing monitoring of herd-specific CCPs, as well as implement corrective actions when CCP alarm values are exceeded

Genome-wide association for milk production and lactation curve parameters in Holstein dairy cows

The aim of this study was to identify genomic regions associated with 305-day milk yield and lactation curve parameters on primiparous (n = 9,910) and multiparous (n = 11,158) Holstein cows. The SNP solutions were estimated using a weighted single-step genomic BLUP approach and imputed high-density panel (777k) genotypes. The proportion of genetic variance explained by windows of 50 consecutive SNP (with an average of 165 Kb) was calculated, and regions that accounted for more than 0.50% of the variance were used to search for candidate genes. Estimated heritabilities were 0.37, 0.34, 0.17, 0.12, 0.30 and 0.19, respectively, for 305-day milk yield, peak yield, peak time, ramp, scale and decay for primiparous cows. Genetic correlations of 305-day milk yield with peak yield, peak time, ramp, scale and decay in primiparous cows were 0.99, 0.63, 0.20, 0.97 and -0.52, respectively. The results identified three windows on BTA14 associated with 305-day milk yield and the parameters of lactation curve in primi- and multiparous cows. Previously proposed candidate genes for milk yield supported by this work include GRINA, CYHR1, FOXH1, TONSL, PPP1R16A, ARHGAP39, MAF1, OPLAH and MROH1, whereas newly identified candidate genes are MIR2308, ZNF7, ZNF34, SLURP1, MAFA and KIFC2 (BTA14). The protein lipidation biological process term, which plays a key role in controlling protein localization and function, was identified as the most important term enriched by the identified genes

The heterogeneity of family: Responses to representational invisibility by LGBTQ parents

This article draws on qualitative research data collected in semi-structured interviews conducted during 2013 and 2014 with 30 lesbian, gay, bisexual, trans, and queer (LGBTQ) parents living in England and Scotland. It explores how LGBTQ parents respond to media representations of families like theirs, and build narratives of family identity from limited cultural resources. Media, encompassing a range of cultural representational resources, including advertisements, television, books and films, produces specific knowledges about LGBTQ families. Participants argued that popular entertainment media (including Modern Family) offered a limited range of representations of LGBTQ parents and concretizes knowledge about the shape of families. I argue that available representations fail to acknowledge the diversity of non-heterosexual family forms and that this representational gap results in socio-cultural invisibility. I explore the responses LGBTQ parents had to such gaps and how they negotiated, or rejected representational meanings in order to consolidate new narratives of family

The Human Capital Risk Reporting of Listed South African Companies: Exploring a Reporting Framework to Support Corporate Governance

Despite the importance and requirement of integrated reporting on human capital (HC), research indicates a lack of reporting frameworks and adequate disclosure in organization reports. Thus, a unique research opportunity is created for researchers to determine what is being presented in reports and how it correlates with human resource management. This article investigates HC reporting practices and proposes a risk reporting framework in support of corporate governance. A qualitative method utilizing qualitative document analysis was followed to analyze a purposive sample (n = 39) of Johannesburg Stock Exchange top 40 listed companies’ annual integrated reports of 2020. Overall, companies followed a widely accepted risk management approach, with inconsistencies in the phases and methods of reporting the risk management phases directed at HC. The magnitude of the risk to the companies is also not understood. The most commonly reported HC risks were employee growth and development, diversity and inclusion, career paths, and employee turnover and turnover intention. Employee work-related well-being was largely neglected. An interesting finding is that the reported risks were metrics-deprived. Current HC practices are backward-looking instead of forward-looking, and they are fragmented. Therefore, an HC reporting framework is suggested for future research that addresses the gaps in integrated reports
