The effect of green tea polyphenols addition on the physicochemical, microbiological and bioactive characteristics of yogurt
Authors: Mediza Romero María Laura , von Staszewski Mariana , Martínez María Julia 
Published: February 2021

PurposeThe purpose of this paper is to evaluate the effect of green tea polyphenols addition on physicochemical, microbiological and bioactive characteristics of yogurt.Design/methodology/approachTwo incorporation methods of polyphenols were evaluated: direct addition or incorporated within protein particles of whey protein concentrate and gelatin. During yogurt’s shelf life, structure characteristics (water holding capacity, textural and rheological parameters), lactic acid bacteria (LAB) viability and polyphenols antioxidant activity were analyzed. Also, polyphenol bioaccesibility afterin vitrodigestion was evaluated.FindingsPolyphenols addition (by the two methods used) did not affect the dynamics of the fermentation process, nor the LAB viability during storage. The color parametera* for the yogurts with the highest polyphenol concentrations showed positive values (tending to red), but not visible to the naked eye. Because of the ability of polyphenols to interact with milk proteins, yogurts with polyphenols presented higher values in firmness and cohesiveness with respect to the control. Additionally, the incorporation of polyphenols in protein particles increased even more these parameters because of the higher protein content of these formulations. After simulated digestion, a high polyphenol bioaccesibility was observed, and the antioxidant activity was retained, which could be explained by the “protector” effect of the milk matrix.Practical implicationsYogurt supplementation with green tea polyphenols is feasible for the development of functional food. However, the use of protein particles would not provide an extra benefit because milk proteins already act as protective molecules of polyphenols.Originality/valueThis study shows not only the physico-chemical implications of including polyphenols in yogurt but also their bioaccesibility after anin vitrodigestion, revealing a suitable manner for delivery of antioxidants in a dairy product like yogurt.

Published: February 2021

PurposeResponding to increasing external pressure, universities are developing new strategies to illustrate the impact of their degrees on graduate employability. This paper investigates how alumni regard the development of their professional networks during their tertiary education in relation to employability and the associated pedagogical implications.Design/methodology/approachA qualitative approach using semi-structured interviews with 18 business and arts alumni from a regional university.FindingsThe findings reveal the importance of developing a professional network by cultivating social capital while at university. Alumni identify all forms of work-integrated learning (WIL), connectedness through social media, the role of university staff and volunteering as concrete ways to develop a professional network and enhance employability.Research limitations/implicationsThis paper has pedagogical implications to develop graduate employability and WIL. Universities should draw from alumni networks to help develop students' bridging capital through industry-facing WIL projects. Educators should design assessment tasks in which students develop contacts and networking capabilities with alumni and other professionals using various platforms (e.g. social media). In addition, educators should promote the benefits of voluntary work and invite alumni and other industry stakeholders to co-design and co-teach areas of curriculum.Originality/valueDrawing from the experiences of alumni re-routes the channel of communication from institutions expressing the importance of professional networks in relation to employability, to credible industry alumni confirming this importance. Few previous studies have taken this “outside-in approach” to emphasise and validate the importance of developing professional networks in relation to employability, particularly at regional universities.
The value of project management to competitiveness: key factors from a holistic and practical perspective
Authors: Silva Cláudia Sousa , Pereira Cláudia , Magano José 
Published: February 2021

PurposeThe contribution of project success and the organisation's efficiency is consensual in the literature. However, the value of project management (PM) brings to the organisation's effectiveness through the alignment with strategy, contributing to its competitiveness and business success, is yet little explored. This study addresses the literature gap that concerns the relationship between PM and the organisation's competitiveness, proposing a holistic conceptual model to understand of how PM brings value to the organisation. This work also aims to demonstrate the practical implications of theoretical contributions to the value of PM. For this, a detailed action research (AR) was planned to show how researchers and practitioners could work and collaborate in a real problem and prove the AR approach's adequacy to the PM field.Design/methodology/approachThe methodology starts with a systematic literature review (SLR), followed by content analysis to develop a conceptual model of PM's value. To validate the theoretical constructs and transfer the results to real context, an AR plan is then carried out to support a specific PM problem presented by an automotive industry company.FindingsThe results have theoretical and practical implications. An original conceptual model is developed–the value of PM: Key factors–defending a multidimensional and holistic perspective to understand the PM's value. A set of key factors was identified, structured, interrelated and exemplified their practical implementation in a single company. In addition to the technical key factors identified in the literature review, the AR plan unveils crucial social aspects to improve PM's value, such as leadership, strong communication and open processes. This work shows the central role of PM methodologies in integrating and interconnecting the key factors, emphasizing the projects' strategic level.Research limitations/implicationsThe present work was developed in a specific and particular organisational context and industry.Practical implicationsThe AR plan presents a company's original programme–Hyper Competitiveness (HC) Temple–implemented in an automotive company. Project management professionals could understand how this company implemented each key factor, defended in a conceptual model and lead the project's results to the business value.Originality/valueThe research originality lies in rethinking PM's value to organisations from a holistic perspective: multi-dimensional, temporal, life cycle, multi-organisational, pointing out a set of technical and social key factors.
An evaluation of offsite construction skill profiles
Authors: Ginigaddara Buddhini , Perera Srinath , Feng Yingbin , Rahnamayiezekavat Payam 
Published: February 2021

Purpose
This paper aims to evaluate the existing and emerging Offsite Construction (OSC) skills. Construction industry is inherently labour oriented, fashioning poor labour productivity, low sustainability, slow and costly processes. These shortcomings promote OSC alongside driving forces such as industrialisation, automation and digitalisation. However, the traditional construction skills are not on par with the complexity, where robots, co-bots and digital-driven automated systems create the need for novel OSC skills.

Design/methodology/approach
Data collection is executed through a Roundtable activity hosting Construction Management academics form Australian universities specialising in construction technology. They engaged in ranking of skills along with creating a word cloud for the question, “what are the future construction skills that will be more beneficial in an OSC platform?” Word cloud is reviewed in a discussion approach while skills ranking data is analysed using descriptive statistics.

Findings
The most prominent OSC skills are logistics manager, project manager and digital producer. Attributes of skills that come under construction trades workers, design, engineering and specialist professionals will vary based on onsite-offsite percentage combination in a construction project. Study reviews the required construction skills at two ends of a continuum featuring the trade-based skills; bricklayer, concreter and carpenter at one end (traditional build) and the heavily digitalised and automated skills at the other end (OSC). The noticeable transition towards OSC urges industry practitioners, policy-makers and education providers to focus on understanding and cultivating key OSC skills.

Originality/value
This study describes the transition of skills from onsite to OSC. It is presented as one of the earliest attempts to evaluate OSC skill profiles.

Web crawler techniques were first exploited to collect takeaway food ordering data from Meituan, the world’s largest GMV platform. Then statistics models and a time series regression model were selected to study the weather impact on online orders.

Findings
The findings highlight that certain weather factors, such as temperature, air quality and rainfall have clear effects on most category takeaway orders.

Originality/value
Quantitative analysis of weather impacts on the takeaway ordering business will help to guide the online service platforms for marketing promotion and the settled businesses to make reasonable arrangements for inventory and marketing tactics.
Designing supply chain performance system: a strategic study on Indian manufacturing sector
Authors: Jha Ajay , Sharma R.R.K. , Kumar Vimal , Verma Pratima 
Published: February 2021

Purpose
A well-designed supply chain performance measurement system, should account for not only the capabilities and performance attributes of the focal firm but also its supply chain partners. The purpose of this paper is to help design a system that strikes a balance between the strategic objectives of the focal firm and its supply partners vis-à-vis the requirements of supply chain performance (cost, quality, speed and customer taste).

Design/methodology/approach
A theoretical framework on the strategic supply chain performance measurement system is developed based on existing literature and subsequently tested using a survey on 136 successful manufacturing organizations in India. The organizations were clustered into three strategy types and compared using analysis of variance on ranks to look for differences in preference for performance parameters.

Findings
The study examined the five dimensions of the supply chain practices, namely, strategic supply/distribution network, customer relationship, internal operations, information sharing and social and environmental responsiveness. The empirical results demonstrate the inclusion of business strategy orientation in designing today’s supply chain and hence its performance measurement system. Not supported hypotheses were addressed in the light of contextual factors.

Research limitations/implications
The study is confined to finding preferences of non-financial aspects of supply chain performance and tier-1 suppliers. The research helps better design and benchmark supply chain performance metrics, based on the strategic choice of the firm.

Originality/value
This paper highlights the shortcomings in the existing performance measurement and gaps in the existing literature in the supply chain context. Further, it gives a holistic view of strategic supply chain performance measurement design.
Long‐term iron deprivation and subsequent recovery uncover heterogeneity in the response of cyanobacterial populations
Authors: Qiu Guo‐Wei , Lis Hagar , Qiu Bao‐Sheng , Keren Nir 
Published: February 2021

SummaryCyanobacteria are globally important primary producers and nitrogen fixers. They are frequently limited by iron bioavailability in natural environments that often fluctuate due to rapid consumption and irregular influx of external Fe. Here we identify a succession of physiological changes in Synechocystis sp. PCC 6803 occurring over 14–16 days of iron deprivation and subsequent recovery. We observe several adaptive strategies that allow cells to push their metabolic limits under the restriction of declining intracellular Fe quotas. Interestingly, cyanobacterial populations exposed to prolonged iron deprivation showed discernible heterogeneity in cellular auto‐fluorescence during the recovery process. Using FACS and microscopy techniques we revealed that only cells with high auto‐fluorescence were able to grow and reconstitute thylakoid membranes. We propose that ROS‐mediated damage is likely to be associated with the emergence of the two subpopulations, and, indeed, a rapid increase in intracellular ROS content was observed during the first hours following iron addition to Fe‐starved cultures. These results suggest that an increasing iron supply is a double‐edged sword ‐ posing both an opportunity and a risk. Therefore, phenotypic heterogeneity within populations is crucial for the survival and proliferation of organisms facing iron fluctuations within natural environments.
What emotional‐centred challenges do children attending special schools face over primary–secondary school transition?
Authors: Bagnall Charlotte L. , Fox Claire L. , Skipper Yvonne 
Published: February 2021

AbstractPrimary–secondary school transition encompasses multiple social, academic and environmental changes which can negatively impact children’s emotional well‐being. Children with Social, Emotional and Mental Health difficulties (SEMH) are believed to be especially vulnerable during this time. However, the voices of children with SEMH are heavily underrepresented in this field within practice and research. The present case study examined how children with SEMH difficulties within one special school experience primary–secondary school transition and how they are supported, in order to make recommendations to improve this period. The case study was qualitative and longitudinal, conducted over 18‐months and methodologies included ethnographic observations, child photo‐elicitation focus groups (with 11 Year 6 children) and three adult interviews. Findings demonstrated that over primary–secondary school transition children with SEMH difficulties (a) negotiate significant structural changes in support (often unanticipated) and (b) need to feel a sense ofsafetyandbelonging. To manage this effectively, transition provision for children with SEMH difficulties needs to consider their short‐term emotional well‐being whilst still in primary school, in addition to their long‐term well‐being looking ahead to secondary school. Greater collaboration and communication across schools and stakeholders can help ensure children receive continuity in standards and support.
Measurements of the dermal exposure to bystanders from direct off‐crop drift during the application of plant protection products

Published: February 2021

AbstractWe determined the dermal exposure of plant protection products containing prothioconazole (PTZ) after spraying a standard crop using a tractor‐operated boom sprayer. Dermal exposure of adult and child bystanders to PTZ and its metabolite, PTZ‐desthio was quantified in bystander drift studies. Exposure was greater on mannequins placed 2 m from the zero line, compared with 5 m or 8 m. When the overall boom height above the ground was the same, the relative boom and canopy heights had no impact on the spray drift, allowing pooling of data from different studies. Wind tunnel experiments were used to compare two flat fan nozzle types, which allowed dermal exposure measured in early bystander field studies using the flat fan TeeJet XR 110 03 nozzle to be adjusted using a conversion factor to reflect exposure from Hypro F110‐03 nozzles. Values from studies using both flat fan nozzle types were pooled and compared with exposure using drift reduction nozzles. For the first time, 3D life‐size mannequins used in field studies have shown that drift reduction nozzles exceed the EFSA‐recommended 50% reduction in drift (potential exposure was reduced by 58–67%). The BREAM2 (Bystander and Resident Exposure Assessment Model) model resulted in better predictions of measured dermal exposure of PTZ equivalents than BREAM, albeit producing more conservative values for the 75th and 95th percentiles of potential dermal exposure compared to field studies (2.6‐fold higher than measured values). Our results using measured potential and actual exposures indicate that the EFSA calculation of 18% protection by light clothing was too conservative.

Published: February 2021

AbstractBackgroundPhosphatidylethanol (PEth) homologs are ethanol metabolites used to identify and monitor alcohol drinking in humans. In this study, we measured levels of the 2 most abundant homologs, PEth 16:0/18:1 and PEth 16:0/18:2, in whole blood samples from rhesus macaque monkeys that drank ethanol daily ad libitum to assess the relationship between PEth levels and recent ethanol exposure in this animal model.MethodsBlood samples were obtained from The Monkey Alcohol Tissue Research Resource. The monkeys were first induced to consume 4% (w/v) ethanol in water from a panel attached to their home cage. Then, monkeys were allowed to drink ethanol and water ad libitum 22 h daily for 12 months and the daily amount of ethanol each monkey consumed was measured. Whole, uncoagulated blood was collected from each animal at the end of the entire experimental procedure. PEth 16:0/18:1 and PEth 16:0/18:2 levels were analyzed by HPLC with tandem mass spectrometry, and the ethanol consumed during the preceding 14 days was measured. Combined PEth was the sum of the concentrations of both homologs.ResultsOur results show that (1) PEth accumulates in the blood of rhesus monkeys after ethanol consumption; (2) PEth homolog levels were correlated with the daily average ethanol intake during the 14‐day period immediately preceding blood collection; (3) the application of established human PEth 16:0/18:1 cutoff concentrations indicative of light social or no ethanol consumption (<20 ng/ml), moderate ethanol consumption (≥ 20 and < 200 ng/ml) and heavy ethanol consumption (≥ 200 ng/ml) predicted significantly different ethanol intake in these animals. PEth homologs were not detected in ethanol‐naïve controls.ConclusionsThis study confirms that PEth is a sensitive biomarker for ethanol consumption in rhesus macaque monkeys. This nonhuman primate model may prove useful in evaluating sources of variability previously shown to exist between ethanol consumption and PEth homolog levels among humans.

SummaryUp to 30% immune thrombocytopenia (ITP) patients achieve a sustained remission off‐treatment (SROT) after discontinuation of thrombopoietin receptor agonists (TPO‐RAs). Factors predictive of response are lacking. Patients aged ≥18 years with newly diagnosed or persistent ITP were treated with eltrombopag for 24 weeks. Primary end‐point was SROT: the proportion of responders that were able to taper and discontinue eltrombopag maintaining the response during a period of observation (PO) of six months. Secondary end‐points included the association between some immunological parameters (TPO serum levels, cytokines and lymphocyte subsets) and response. Fifty‐one patients were evaluable. Primary end‐point was achieved in 13/51 (25%) treated patients and 13/34 (38%) patients who started the tapering. Baseline TPO levels were not associated with response at week 24 nor with SROT. Higher baseline levels of IL‐10, IL‐4, TNF‐α and osteopontin were negative factors predictive of response (P = 0·001, 0·008, 0·02 and 0·03 respectively). This study confirms that SROT is feasible for a proportion of ITP patients treated with eltrombopag. Some biological parameters were predictive of response.
