Value Co-Destruction: a Text-Mining-Based Mixed Method Study on Social Media Interactions

To better understand how big data interconnects firms and customers, we analyse the role of customers’ emotions in the process of value co-destruction in a social media context. We perform a text mining based algorithm capable of identifying anger, expectation, disgust, fear, and sadness in peaks of problematic social interactions. The developed algorithm associated with an in-depth qualitative analysis shows how to employ unstructured big data to understand the role of negative emotions in the process of value co-destruction

Agri-food firms’ attitude toward digital data exploitation in the product development

THE AIMS OF THE PAPER: This paper explores digital data exploitation behaviours and shows how these conducts change according to the data sources used by agri-food firms when developing their products. METHODOLOGY: We adopt an exploratory multiple-case study to provide a theoretical framework for agri-food firms utilising digital data for product development. MOST IMPORTANT RESULTS: The article shows two prominent firms’ behaviours that we labelled data explorers and data receivers and a third behaviour which is a combination of the main ones. RECOMMENDATIONS: This article offers guidelines to support agri-food firms to distinguish how such firms may benefit from the digital transformation by gaining competitiveness improving production efficiency and supporting the development of their products

Digital Transformation Through the Lens of Digital Data Handling: An Exploratory Analysis of Agri-Food SMEs

This study aims to explore digital transformation and the level of sophistication in the digital data handling strategy by agri-food small and medium-sized enterprises (SMEs). By developing an exploratory multiple-case study that involves fourteen food processing SMEs, this paper identifies a data processing flow made up of the following phases: data generation, data acquisition, data storage, data analysis, and data exploitation. In addition, it shows how data processing flow may occur in a number of ways, thereby classifying the agri-food SMEs’ digital transformation as paper master, digital wannabe, and digital champion. Hence, the article contributes to providing the conceptualization of a data processing flow, which includes the progressive stages in data management identified across firms by proposing a data handling strategy framework. Such a framework offers a snapshot of firms at various levels of digitization in their handling of various kinds of data, thus clarifying how the strategies of data processing flow occur

Time to clean up food production? Digital technologies, nature-driven agility, and the role of managers and customers

This article employs a multiple-case study research design to unpack the complex relationship between digital transformation, agility, and environmental sustainability in the agri-food industry. Our findings show that to achieve a cleaner food production that does not compromise the natural life cycle, firms need to deploy naturedriven agility, a novel type of agility. We conceptualized nature-driven agility as the firm ability to flexibly and effectively utilize natural resources to adapt the full production process to market changes and capture new value-creation opportunities within nature constraints. This study found that nature-driven agility relies on digital technologies to make predictions about natural resource dynamics that may impact the critical steps of the agri-food production process. We also identify some factors that clarify how the benefits of nature-driven agility on cleaner food production strongly depend on managers’ commitment to environmental sustainability and the pressure of customers for new products aligned with ecological sustainability purposes. Finally, we synthesized the findings in the Nature-driven Agility (NaDrA) framework, which practitioners can use to design proper operations that capture value-creation opportunities while improving agri-food firms’ environmental performance

DNA integrity and viability of testicular cells from diverse wild species after slow freezing or vitrification

Introduction and objectiveCryopreservation of testicular tissues offers new possibilities to protect endangered species, genetically valuable individuals or even the fertility potential of prepubertal individuals who have died unexpectedly. However, the use of this technique still remains a challenge. In this study, slow freezing and vitrification of testicular tissue was investigated to find out which cryopreservation method could better preserve the viability and DNA integrity of testicular germ cells in diverse wild species.MethodsTestes were obtained post-mortem from 18 artiodactyls (wild boar, roe deer, dwarf goat, mhor gazelle, European mouflon, African forest buffalo, Malayan tapir, dorcas gazelle, Iberian ibex, gnu, red river hog), 5 primates (colobus monkey, capuchin monkey, mandrill), 8 carnivores (gray wolf, Persian leopard, binturong, European mink, American black bear, suricata), and 2 rodents (Patagonian mara). The testicles belonged to adult individuals and were cut into small pieces and cryopreserved by needle immersed vitrification or uncontrolled slow freezing using a passive cooling device. After warming or thawing, testicular tissues were enzymatically digested and two germ cell types were differentiated based on their morphology: rounded cells (spermatogonia, spermatocytes, and early spermatids) and elongated cells (elongated spermatids and spermatozoa). Cell viability was assessed by SYBR-14/propidium iodide while DNA fragmentation by TUNEL assay with fluorescence microscope.Results and discussionOur preliminary results revealed that our uncontrolled slow freezing method better preserved the viability and DNA integrity of elongated cells than vitrification. Such trend was observed in all species, being significant in artiodactyls, carnivores, and primates. Similarly, the viability and DNA integrity of rounded cells was also better maintained in primates by uncontrolled slow freezing, while in carnivores, vitrification by needle immersion showed better results in this type of cells. In artiodactyls and rodents both techniques preserved the viability of rounded cells in a similar manner, although the DNA integrity of these cells was greater after needle immersed vitrification in artiodactyls.ConclusionsIn conclusion, the effectiveness of each cryopreservation method is affected by the phylogenetic diversity between species and cell type

Observation of the doubly charmed baryon decay Ξcc++→Ξc′+π+

The Ξcc++→Ξc′+π+ decay is observed using proton-proton collisions collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb−1. The Ξcc++→Ξc′+π+ decay is reconstructed partially, where the photon from the Ξc′+→Ξc+γ decay is not reconstructed and the pK−π+ final state of the Ξc+ baryon is employed. The Ξcc++→Ξc′+π+branching fraction relative to that of the Ξcc++→Ξc+π+ decay is measured to be 1.41 ± 0.17 ± 0.10, where the first uncertainty is statistical and the second systematic.

Test of lepton universality in b→sℓ+ℓ−b \rightarrow s \ell^+ \ell^- decays

The first simultaneous test of muon-electron universality using $B^{+}\rightarrow K^{+}\ell^{+}\ell^{-}$ and $B^{0}\rightarrow K^{*0}\ell^{+}\ell^{-}$ decays is performed, in two ranges of the dilepton invariant-mass squared, $q^{2}$. The analysis uses beauty mesons produced in proton-proton collisions collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9 $\mathrm{fb}^{-1}$. Each of the four lepton universality measurements reported is either the first in the given $q^{2}$ interval or supersedes previous LHCb measurements. The results are compatible with the predictions of the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-046.html (LHCb public pages

Study of charmonium and charmonium-like contributions in B+ → J/ψηK+ decays

A study of B+→ J/ψηK+ decays, followed by J/ψ → μ+μ− and η → γγ, is performed using a dataset collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb−1. The J/ψη mass spectrum is investigated for contributions from charmonia and charmonium-like states. Evidence is found for the B+→ (ψ2(3823) → J/ψη)K+ and B+→ (ψ(4040) → J/ψη)K+ decays with significance of 3.4 and 4.7 standard deviations, respectively. This constitutes the first evidence for the ψ2(3823) → J/ψη decay
