Effects of lipids on the water sorption, glass transition and structural strength of carbohydrate-protein systems

peer-reviewedEncapsulant systems are gaining wide practical interest due to their functional and nutritional properties. This paper was focusing on understanding structural relaxations in that systems near glass transition temperature. Freeze-dried trehalose-whey protein isolate-sunflower oil systems with various ratios of the last were used as a carbohydrate-protein-lipid food model. The Guggenheim-Anderson-de Boer (GAB) water sorption relationship was used as a tool to model water sorption isotherms. The glass transition temperature was obtained by differential scanning calorimetry (DSC). Structural α-relaxation temperatures were measured by dynamical mechanical analyses (DMA), dielectric analysis (DEA) and combined to cover a broad range for strength assessment. The microstructure was characterized by optical light microscopy, confocal laser scanning microscopy and scanning electron microscopy. The C1 and C2 constants for Williams-Landel-Ferry (WLF) equation and structural strength parameter were calculated for each system. The effect of sunflower oil and water contents on strength of carbohydrate-protein system was analyzed. Strength shows decreasing with increasing of lipid concentration in the mixtures and more complex dependence on the water content in a system.This investigation was supported by the Food Institutional Research Measure (FIRM) project “Formulation and Design for Food Structure and Stability” funded by the Department of Agriculture, Food and Marine (11-F-001), coordinated by prof.

Speaking Right: HRDs Role in Mediating Good Boardroom Conversations

Purpose This paper aims to explore the impact discourse has on decision making practices within the boardroom and considers how personal proficiency in micro-language use can enhance an individual’s personal efficacy in influencing boardroom decisions. The work uses Habermas’ theory of communicative action to critique board talk, highlighting the need for greater understanding of the power of everyday taken for granted talk in strategy shaping. It illuminates the contribution that human resource development (HRD) professionals can make to the management of such behaviour and minimising dysfunctional behaviour and enabling effective boardroom practices. Design/methodology/approach Traditional governance theory from a business and organisational perspectives are provided before considering the boardroom environment and HRD’s role. The authors undertake ethnographic research supported by conversation analysis to explore how directors use talk-based interpersonal routines to influence boardroom processes and enact collective decision making. The authors provide one extract of directors’ talk to illustrate the process and demonstrate what the data “looks like” and the insights it holds. Findings The analysis suggests that the established underlying assumptions and rationale ideologies of corporate governance are misplaced and to understand the workings of corporate governance HRD academics and professionals need to gain deeper insight into the employment of talk within boards. Armed with such insights HRD professionals can become more effective in developing strategies to address dysfunctional leadership and promote good governance practice throughout their organisation. Social implications The work raises a call for HRD to embrace a societal mediation role to help boards to become a catalyst for setting good practice which is strategically aligned throughout the organisation. Such roles require a more dialogical, strategic and critical approach to HRD, and professionals and academics take a more holistic approach to leadership development. Originality/value The paper considers the role of the development of HRD interventions that both help individuals to work more effectively within a boardroom environment and support development to shape a boardroom culture that promotes effective governance practice by influencing boardroom practice thereby promoting strong governance and broad social compliance throughout the organisation

Foresight and action learning supporting transition: An account of practice

Integrating foresight into corporations has proved to be challenging. This account of practice reports on the introduction of futures and foresight (FF) teaching content into an executive Masters programme. The FF contentwas further linked to and provided a background for action learning sets. The purpose was to identify how introducing distant time horizons would help participants to adapt and change their perspectives in problem solving and professional development. The report describes how FF was incorporated across the programme and used to develop insightful conversations in the action learning sets. Citing two case examples, the authors reflect on how participants responded to these new elements and offer insights into the value of introducing FF as an interdisciplinary element in a programme

Search for the disappearance of muon antineutrinos in the NuMI neutrino beam

We report constraints on muon antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4 +/- 11.7(stat) ^{+10.2}_{-8.9}(syst) events under the assumption |dm2bar|=2.32x10^-3 eV^2, snthetabar=1.0. A fit to the two-flavor oscillation approximation constrains |dm2bar|<3.37x10^-3 eV^2 at the 90% confidence level with snthetabar=1.0

‘Plasticosis’: Characterising macro- and microplastic-associated fibrosis in seabird tissues

As biota are increasingly exposed to plastic pollution, there is a need to closely examine the sub-lethal 'hidden' impacts of plastic ingestion. This emerging field of study has been limited to model species in controlled laboratory settings, with little data available for wild, free-living organisms. Highly impacted by plastic ingestion, Flesh-footed Shearwaters (Ardenna carneipes) are thus an apt species to examine these impacts in an environmentally relevant manner. A Masson's Trichrome stain was used to document any evidence of plastic-induced fibrosis, using collagen as a marker for scar tissue formation in the proventriculus (stomach) of 30 Flesh-footed Shearwater fledglings from Lord Howe Island, Australia. Plastic presence was highly associated with widespread scar tissue formation and extensive changes to, and even loss of, tissue structure within the mucosa and submucosa. Additionally, despite naturally occurring indigestible items, such as pumice, also being found in the gastrointestinal tract, this did not cause similar scarring. This highlights the unique pathological properties of plastics and raises concerns for other species impacted by plastic ingestion. Further, the extent and severity of fibrosis documented in this study gives support for a novel, plastic-induced fibrotic disease, which we define as 'Plasticosis,'.Copyright © 2023 The Authors.

Teacher Fellow Accreditation – A madrigal of voices! But is it the right tune? Tensions of standardisation, engagement and neoliberalism

Purpose The purpose of this paper is to explore the impact competency frameworks as standardisation can have on the employee engagement of academic staff within higher education (HE) through their employment as managerial tools. Design/methodology/approach A literature review is conducted from which the conditions for effective competency frameworks are evaluated and the influence of changes in the HE environment in the form of political agendas and tight resources are explored. Findings This paper provides insights into the dynamics of public service modernisation and the tensions between the dominant discourse of managerialism and the degree of agency afforded to professional academics. It highlights the relevance of informal peer relationships in setting the climate to generate collegial bonding and professional engagement that underpin successful teacher fellowship accreditations. It further highlights the key role managers play in this process and provides a conceptual framework highlighting the dynamics and combined effect of employee engagement and competency frameworks set within complex HE environment. Practical implications This paper brings together the prerequisites for effective implementation of competency frameworks to implement successful employee engagement strategies set within the complexities of the HE context, which has not been studied to date. Armed with such insights, Human Resource Development (HRD) departments and universities can implement competency assessments that generate greater staff engagement. Originality/value The paper provides a critical approach in reviewing the impact of Continued Professional Development and its link to professional status and thus helps British Universities and others to understand how the mechanisms at work affect engagement levels of academic staff. Armed with this depth of understanding of how the change initiative works, with whom and under what circumstances, universities will be better able to meet target UK Professional Standards Framework membership levels required by the higher education academy (HEA) and, subsequently, the HEA to meet their targets for the government

Mindfulness-based interventions for young offenders: a scoping review

Youth offending is a problem worldwide. Young people in the criminal justice system have frequently experienced adverse childhood circumstances, mental health problems, difficulties regulating emotions and poor quality of life. Mindfulness-based interventions can help people manage problems resulting from these experiences, but their usefulness for youth offending populations is not clear. This review evaluated existing evidence for mindfulness-based interventions among such populations. To be included, each study used an intervention with at least one of the three core components of mindfulness-based stress reduction (breath awareness, body awareness, mindful movement) that was delivered to young people in prison or community rehabilitation programs. No restrictions were placed on methods used. Thirteen studies were included: three randomized controlled trials, one controlled trial, three pre-post study designs, three mixed-methods approaches and three qualitative studies. Pooled numbers (n = 842) comprised 99% males aged between 14 and 23. Interventions varied so it was not possible to identify an optimal approach in terms of content, dose or intensity. Studies found some improvement in various measures of mental health, self-regulation, problematic behaviour, substance use, quality of life and criminal propensity. In those studies measuring mindfulness, changes did not reach statistical significance. Qualitative studies reported participants feeling less stressed, better able to concentrate, manage emotions and behaviour, improved social skills and that the interventions were acceptable. Generally low study quality limits the generalizability of these findings. Greater clarity on intervention components and robust mixed-methods evaluation would improve clarity of reporting and better guide future youth offending prevention programs
