Towards an increased understanding of learning: a case study of a collaborative relationship between a retailer and a logistics service provider
Authors: Haag Linnea , Sandberg Erik , Sallnäs Uni 
Published: December 2021

PurposeThis study aims to explain how learning occurs in collaborative retailer–logistics service provider (LSP) relationships. The research is guided by two research questions, addressing absorptive and desorptive capacities and the interaction between these capacities.Design/methodology/approachThe study is based on a case study of a Swedish, collaborative retailer–LSP dyad. The empirical data are structured around five specific learning situations within the retailer–LSP dyad.FindingsThe findings provide an explanation for how learning occurs within a collaborative retailer–LSP relationship based on subprocesses of absorptive and desorptive capacities. The interaction between these processes is found to rely on two types of support: one-directional and bidirectional. The findings also indicate positive outcomes of learning, such as improved cost efficiencies in warehouse operations, better customer services and improved long-term strategic planning.Practical implicationsThis study shows how retailers and LSPs can learn from each other and together create an improved logistics system for end customers.Originality/valueThis research takes into account absorptive and desorptive capacities in a collaborative retailer–LSP relationship. This study enhances the understanding of inter-organisational learning processes in a retail logistics context.
Cross-fertilization of knowledge and technologies in collaborative research projects

Published: December 2021

PurposeThis paper aims to explore how the cross-fertilization of knowledge and technologies in EU-funded research projects, including serious games and gamification, is influenced by the following variables: multidisciplinarity, knowledge base and organizations (number and diversity). The interrelation of actors and projects form a network of innovation. The largest contribution to cross-fertilization comes from the multidisciplinary nature of projects and the previous knowledge and technology of actors. The analysis draws on the understanding of how consortia perform as an innovation network, what their outcomes are and what capabilities are needed to reap value.Design/methodology/approachAll the research projects including serious games and/or gamification, funded by the EU-Horizon 2020 work programme, have been analyzed to test the hypotheses in this paper. The study sample covers the period between 2014 and 2016 (June), selecting the 87 research projects that comprised 519 organizations as coordinators and participants, and 597 observations – because more organizations participate in more than one project. The data were complemented by documentary and external database analysis.FindingsTo create cross-fertilization of knowledge and technologies, the following emphasis should be placed on projects: partners concern various disciplines; partners have an extensive knowledge base for generating novel combinations and added-value technologies; there is a diverse typology of partners with unique knowledge and skills; and there is a limited number of organizations not too closely connected to provide cross-fertilization.Research limitations/implicationsFirst, the database sample covers a period of 30 months. The authors’ attention was focused on this period because H2020 prioritized for the first time the serious games and gamification with two specific calls (ICT-21–14 and ICT-24–16) and, second, for the explosion of projects including these technologies in the past years (Adkins, 2017). These facts can be understood as a way to push the research to higher technology readiness levels (TRLs) and introducing the end-user in the co-creation and co-development along the value chain. Second, an additional limitation makes reference to the European focus of the projects, missing strong regional initiatives not identified and studied.Originality/valueThis paper has attempted to explore and define theoretically and empirically the characteristics found in the cross-fertilization of collaborative research projects, emphasizing which variables, and how, need to be stimulated to benefit more multidisciplinary consortia and accelerate the process of innovation.
Turning visions into results: unraveling the distinctive paths of leading with vision and autonomy to goal achievement
Authors: Maran Thomas K. , Baldegger Urs , Klösel Kilian 
Published: December 2021

PurposeLeading with vision while granting employees autonomy is one effective organizational response to the demands of a dynamic external environment. The former is thought to align followers' behavior by providing guidance, the latter to increase variance in their behavior by relinquishing control; both exert beneficial but distinct effects on organizational performance. What has remained uncharted heretofore is how these leader behaviors shape their followers' cognition and, subsequently, yield improvements in performance. The authors argue that a leader's vision communication transforms followers' cognitive representation of their work. This not only enables them to specify their goals in alignment with the vision (goal clarity) but also to locate the meaning of their work within the bigger picture of the vision (construal level). By contrast, perceived autonomy in terms of power-sharing might directly affect followers' work engagement more narrowly.Design/methodology/approachThe authors tested the model on a sample of 408 employees from eleven enterprises of a holding company. In the survey, employees reported perceived vision communication and autonomy provided by their leader. Furthermore, the authors assessed the employees' goal attainment. To capture how employees represent their daily work activities, the authors measured their construal level and their goal clarity.FindingsThe results show that both perceived vision communication and granted autonomy improve employees' goal achievement. Moreover, two processes mediate the relationship between vision communication and goal achievement in followers: first, specifying goals in terms of clarity; second, composing a higher-level mental construal of their work. In contrast, no mediation of empowering leader behaviors was found.Originality/valueBetter goal achievement through visionary leadership is therefore achieved through cognitive alignment of followers, while leader-granted autonomy acts as a motivational tool directly on performance.
High variation in hydraulic efficiency but not xylem safety between roots and branches in four temperate broad‐leaved tree species

Abstract

Xylem hydraulic safety and efficiency are key traits determining tree fitness in a warmer and drier world. While numerous plant hydraulic studies have focused on branches, our understanding of root hydraulic functioning remains limited, although roots control water uptake, influence stomatal regulation and have commonly been considered as the most vulnerable organ along the hydraulic pathway.

We investigated 11 traits related to xylem safety and efficiency along the hydraulic pathway in four temperate broad‐leaved tree species.

Continuous vessel tapering from coarse roots to stems and branches caused considerable reduction in hydraulic efficiency. Wood density was always lowest in roots, but did not decline linearly along the flow path. In contrast, xylem embolism resistance (P50) did not differ significantly between roots and branches, except for one species. The limited variation in xylem safety between organs did not adequately reflect the corresponding reductions in vessel diameter (by ~70%) and hydraulic efficiency (by ~85%). Although we did not observe any trade‐off between xylem safety and specific conductivity, vessel diameter, vessel lumen fraction and wood density were related to embolism resistance, both across and partly within organs.

We conclude that coarse roots are not highly vulnerable to xylem embolism as commonly believed, indicating that hydraulic failure during soil drying might be restricted to fine roots.

How Do Mutual Dependence and Power Imbalance Condition the Effects of Technological Similarity on Post‐acquisition Innovation Performance Over Time?
Authors: Wu Jie , Yu Luman , Khan Zaheer 
Published: December 2021

AbstractThis study investigates how mutual dependence and power imbalance, which have been differentiated by recent studies adopting the theoretical lens of resource dependence theory (RDT) as two distinct forms of interdependence, change the effect of technological similarity between the acquiring firm and the target firm on post‐acquisition innovation across times. The analysis of panel data on mergers and acquisitions undertaken by US firms reveals that in the short‐run, mutual dependence strengthens the effect of technological similarity on post‐acquisition innovation, whereas power imbalance weakens it. However, the effect of mutual dependence persists over time, while that of power imbalance declines over time. These findings extend the RDT to the context of technological acquisition and innovation and offer important implications for research and practice.
The impossibility of engaged research: Complicity and accountability between researchers, ‘publics’ and institutions
Authors: Heney Veronica , Poleykett Branwyn 
Published: December 2021

AbstractOver the past decade, U.K. universities have increasingly sought to involve publics in research as active participants in the construction of academic knowledge. Sociologists of health have largely welcomed this enthusiasm for engaged and participatory ways of working, including methodologies long in use in the field such as patient‐led research and co‐creation. Despite the strong interest in engaged research, however, we argue that funding patterns, bureaucratic structures and an overreliance on people employed on casual contracts make it extremely difficult, often impossible, to do engaged research in British universities. Drawing on our own experiences, we show how our attempts to practise and deepen accountability to variously situated publics were constrained by the way our institution imagined and materially supported engagement. We argue that it falls to individual researchers to mitigate or work around structural barriers to engagement, and that this process creates dilemmas of complicity. If engaged research is to fulfil its remit for inclusion and its radical potential, researchers need to think carefully about how the U.K. engagement agenda entwines with processes of casualisation, acceleration and projectification, and how institutional recuperations of engagement can undermine its political and epistemic objectives.
From oasis to outlier: sugar beets, an endangered fish, and the moral economy
Authors: Gewertz Deborah , Errington Frederick 
Published: December 2021

AbstractFarmers in the arid high plains of Eastern Montana had long irrigated with water shunted into their fields by a dam on the Yellowstone River. Growing water‐hungry sugar beets processed at a factory in a nearby town, they created a verdant and prosperous oasis: a good life nested within a satisfyingly moral economy. However, in short order, the economic basis of this life was challenged: the dam was threatened with removal because of claims that it adversely affected an endangered fish; and the factory was threatened with closure because of claims that it was insufficiently profitable. As farmers and townsfolk confronted these challenges and the motives of those making them, they were compelled to probe the fundamental questions of what is ‘moral’ and what is ‘economy’. Confronting their uncertain future, they wondered whether their oasis was to become an outlier.
Who talks about what? Issue strategies across the party hierarchy

Published: December 2021

AbstractWe combine the recent literature on issue competition with work on intra‐party heterogeneity to advance a novel theoretical argument. Starting from the premise that party leaders and non‐leaders have different motivations and incentives, we conjecture that issue strategies should vary across the party hierarchy. We, therefore, expect systematic intra‐party differences in the use ofriding the waveandissue ownershipstrategies. We test this claim by linking public opinion data to manually coded information on over 3600 press releases issued by over 500 party actors across five election campaigns in Austria between 2006 and 2019. We account for self‐selection into leadership roles by exploiting transitions into and out of leadership status over time. The results show that party leaders are more likely than non‐leaders to respond to the public's issue priorities, but not more or less likely to pursue issue‐ownership strategies.
Inhibition of DNA methyltransferase aberrations reinstates antioxidant aging suppressors and ameliorates renal aging

Published: December 2021

AbstractDNA methylation alterations play mechanistic roles in aging; however, the epigenetic regulators/mediators causally involved in renal aging remain elusive. Here, we report that natural and D‐galactose (D‐gal)‐induced aging kidneys display marked suppression of antiaging factor NRF2 (nuclear factor erythroid‐derived 2‐like 2) and KLOTHO, accompanied by upregulations of DNA methyltransferase (DNMT) 1/3a/3b and NRF2/KLOTHO gene promoter hypermethylations. Administration of a DNMT inhibitor SGI‐1072 effectively hypomethylated the promoters, derepressed NRF2/KLOTHO, and mitigated the structural and functional alterations of renal aging in D‐gal mice. Moreover, oleuropein (OLP), an olive‐derived polyphenol, also displayed similar epigenetic modulation and antiaging effects. OLP inhibited the epigenetic NRF2/KLOTHO suppressions in a gain of DNMT‐sensitive manner in cultured renal cells, demonstrating a strong DNA‐demethylating capacity. In NRF2 knockout and KLOTHO knockdown D‐gal mice, OLP exhibited reduced antiaging effects with KLOTHO displaying a prominent gene effect and effect size; consistently in KLOTHO knockdown mice, the antiaging effects of SGI‐1027 were largely abrogated. Therefore, the KLOTHO recovery is critical for the antiaging effects of DNA demethylation. Collectively, our data indicate that aberrant DNMT1/3a/3b elevations and the resultant suppression of antiaging factors contribute significantly to epigenetic renal aging, which might be targeted for epigenetic intervention by synthetic or natural DNA‐demethylating agents.
The estimated impact of state‐level support for expanded delivery of substance use disorder treatment during the COVID‐19 pandemic
Authors: Nesoff Elizabeth D. , Marziali Megan E. , Martins Silvia S. 
Published: December 2021

AbstractBackground and AimsTo prevent COVID‐19 transmission, some United States (US) federal regulations on substance use disorder (SUD) treatment were suspended in March 2020. This study aimed to quantify the extent of state‐level policy uptake and the potential number of people with SUD affected by these policy changes across the US, as well as to assess if policy uptake correlated with rates of people with SUD already in treatment or needing treatment.DesignCross‐sectional analysis of policies implemented as of April 13, 2020.Setting and ParticipantsA total of 50 US states and the District of ColumbiaMeasurementsState‐level implementation of: oral schedule II controlled substances emergency prescription, extended take‐home doses for medication for opioid use disorders (MOUD), home‐delivery of take‐home medications, telemedicine for schedule II‐IV prescriptions, telemedicine for buprenorphine prescribing initiation, and waiver of out‐of‐state Drug Enforcement Administration (DEA) registration. Rates per 100 000 population of: adults in treatment for SUD, MOUD treatment at facilities with opioid treatment programs, SUD based on Diagnostic and Statistical Manual of Mental Disorders (DSM)‐IV criteria, and needing, but not receiving treatment.FindingsHalf of the states (n = 24) enacted no policies, leaving ~460 955 people in treatment and 114 370 people on MOUD pre‐pandemic uncovered by any policy expansion. Only telemedicine for buprenorphine initiation was marginally associated with pre‐pandemic rate of SUD treatment (OR = 1.003, 95% CI = [1.001, 1.006]) and rate of MOUD therapy (OR = 1.006, 95% CI = [1.002, 1.011]) in univariable analysis, but these associations were no longer significant when controlling for state‐level demographics. No policies were associated with state‐wide SUD prevalence or rate of unmet treatment need (P > 0.05).ConclusionsTwenty‐four United States states did not implement at least one federal policy for substance use disorder treatment expansion as of April 2020, leaving approximately half a million people in treatment pre‐pandemic potentially without access to treatment or risking exposure to COVID‐19 to continue in‐person therapies.

AbstractBackgroundIn the PRESERVE‐EF study, a two‐step sudden cardiac death (SCD) risk stratification approach to detect post‐myocardial infarction (MI) patients with left ventricle ejection fraction (LVEF) ≥40% at risk for major arrhythmic events (MAEs) was used. Seven noninvasive risk factors (NIRFs) were extracted from a 24‐h ambulatory electrocardiography (AECG) and a 45‐min resting recording. Patients with at least one NIRF present were referred for invasive programmed ventricular stimulation (PVS) and inducible patients received an Implantable Cardioverter ‐ Defibrillator (ICD).MethodsIn the present study, we evaluated the performance of the NIRFs, as they were described in the PRESERVE‐EF study protocol, in predicting a positive PVS. In the PRESERVE‐EF study, 152 out of 575 patients underwent PVS and 41 of them were inducible. For the present analysis, data from these 152 patients were analyzed.ResultsAmong the NIRFs examined, the presence of signal averaged ECG‐late potentials (SAECG‐LPs) ≥ 2/3 and non‐sustained ventricular tachycardia (NSVT) ≥1 eposode/24 h cutoff points were important predictors of a positive PVS study, demonstrating in the logistic regression analysis odds ratios 2.285 (p = .027) and 2.867 (p = .006), respectively. A simple risk score based on the above cutoff points in combination with LVEF < 50% presented high sensitivity but low specificity for a positive PVS.ConclusionCutoff points of NSVT ≥ 1 episode/24 h and SAECG‐LPs ≥ 2/3 in combination with a LVEF < 50% were important predictors of inducibility. However, the final decision for an ICD implantation should be based on a positive PVS, which is irreplaceable in risk stratification.

AbstractMagnolol is a multifunctional polyphenol rich in Magnolia officinalis. The objective of this study was to investigate the effects of magnolol on growth performance, carcass traits, antioxidant capacity, and gut health of broiler chickens. A total of 240 1‐day‐old broilers were randomly allocated into five dietary treatments: control (Ctrl); control diet supplemented with 100, 200, or 300 mg/kg of magnolol (M100, M200, and M300); and control diet supplemented with 200 mg/kg of bacitracin zinc (PC). The results showed that magnolol linearly decreased the feed conversion ratio between d 0 and d 14, linearly decreased the amount of malondialdehyde and increased the activity of total superoxide dismutase (T‐SOD) in both serum and ileal mucosa on d 42 with increasing magnolol levels (p < 0.05). Moreover, the ileal villus height, the ileal villus height to crypt depth ratio, and the jejunal gene expressions of SOD1, glutathione peroxidase, and Claudin1 were linearly up‐regulated with increasing magnolol levels (p < 0.05). The supplementation of magnolol had no effect on carcass traits or cecal short chain fatty acids (p > 0.05). The results indicated that magnolol could be applied in the diet of broiler chickens to benefit their antioxidant capacity and intestinal health.

SummaryPatients with haemato‐oncological malignancies are one of the high‐risk groups for a severe course in case of COVID‐19 infections. Furthermore, vaccination results in significantly lower response rates in haematological malignancies and lower antibody levels in patients with solid cancer. We investigated efficacy and safety of a heterologous booster vaccination with Ad26.COV2.S DNA vector vaccine in haemato‐oncological patients without antibody response after double‐dose BNT162b2 messenger (m‐)RNA COVID‐19 vaccine. A total of 32 haemato‐oncological non‐responders to double‐dose BNT162b2 received a heterologous booster vaccination with Ad26.COV2.S. Blood samples were assessed directly before the vaccination (T0) and four weeks after (T1). Safety assessment was performed using a standardised questionnaire. The overall response rate was 31%, with a mean (SD) antibody titre of 693·79 (1 096·99) binding activity units (BAU)/ml. Patients with chronic lymphocytic leukaemia or lymphoma showed a significantly lower response rate (P = 0·048). Adverse events were reported in 29·6% of patients, of which 7·1% were graded as severe, including grade III and IV events following the Common Terminology Criteria of Adverse Events (CTCAE). The heterologous booster vaccination with Ad26.COV2.S led to a serological response in nine out of 29 patients without response after double‐dose BNT162b2. Furthermore, the vaccination was safe in our cohort, leading to mainly mild local and systemic reactions. Overall, this vaccination regimen should be further evaluated to increase the response rate in the highly vulnerable population of haemato‐oncological patients.
