Innovation logics in the digital era: a systemic review of the emerging digital innovation regime

ABSTRACT This essay reviews the ontological status of digital material in industrial operations and conditions it provides for innovation. It recognises the semiotic quality of digital material and the critical role of von Neumann architecture as to show that digital innovation advances through a three pronged, largely orthogonal process of embedding- a process of interlacing elements of one innovation domain to that of another. Three types of embedding define digital innovation: operational embedding (code-computer), virtual embedding (real-world phenomena-code) and contextual embedding (performing code-social setting). Each constitutes a ‘leverage point’ for further expanding digital innovation and they interact dynamically while industrial innovation is defined by a static virtual and contextual embedding. The processes that underlie innovation in the two regimes follow differential logics. In industrial regime (1) discover-synthesise and (2) manufacture-distribute activities combine to form the leverage points for innovation. In digital regime 1) discover product or behaviour (ideation); 2) abstract to digital material (virtualise); 3) Implement and replicate digital material (variations in operational/contextual embedding); and 4) Deliver product and/or behaviour (perform digital material) activities form the leverage points for innovation enabling wider, open, and faster innovation with a distinct value logic.
nvited commentary role for MMP-3 genetic variation in atherosclerosis susceptibility?

Matrixmetalloproteinases (MMPs) area large familyof enzymes hat cleave components of the extracellularmatrix.Manymembers f this family are expressed by the cells constituting the vascular all and atherosclerotic plaques [1], and they may play multiple oles in thevascular changes associatedwithatherosclerosis.MMPs re implicated in both adaptive remodeling and smooth muscle ell migration which may aid the development of stable plaques. onversely, extracellular matrix degradation is also involved in laque rupture and aneurysm formation. Thus the involvement of hese enzymes in cardiovascular pathologies is complex. For furher information, the comprehensive review by Newby provides n excellent description of the roles of MMPs in atherosclerotic isease [1]. Matrix metalloproteinase 3 (MMP-3), also known as tromelysin-1, has a variety of known substrates including ollagen and proteoglycans, and plays a role in the activation of ther MMPs [2]. It has been found in the shoulder lipid-rich areas f atherosclerotic plaques and is expressed by, and upregulated n, foam cells [1]. ApoE deficient mice lacking MMP-3 have larger esion areas with increased buried fibrous layers and reduced mooth muscle cell content, suggesting reduced stability of these esions [3]. A second study also observed larger lesions with ncreased macrophage accumulation and collagen deposition, but ewer aneurysms in MMP-3 knockout apoE deficient mice [4]. n humans, reduced serum concentrations of MMP-3 have been easured in individuals who have had a myocardial infarction MI), and a negative correlation between serum levels of MMP-3 nd atherosclerotic plaque area was found in females [5]. MMP-3 lasma levels have also recently been correlated with in-stent estenosis [6]. These studies suggest complex, multiple roles of MP-3 in the vascular wall and potentially differential effects of MP-3 on lesion size versus stability.
Change through chaos: using bricolage in cross-sector social partnerships

PurposeThe purpose of this paper is to explore bricolage as the missing link in understanding how cross-sector social partnerships form and operate in response to grand challenges. It is proposed that the weaving together of resources employed by members of cross-sector social partnerships (CSSPs) is bricolage in action and can be linked to Gray's (1985) facilitating conditions for collaboration. While existing research examines bricolage primarily at the individual level, this research studies collective bricolage, as implemented by a cross-sector social partnership in its process to address a grand challenge.Design/methodology/approachThe authors follow the evolution of a Midwestern initiative aimed at the grand challenge of generational poverty. The deductive case study approach identifies the mechanisms of bricolage being employed in the initiative's evolution and ties these to Gray's (1985) seminal paper on interorganizational collaboration.FindingsThis case study has implications for academics conceptually struggling to understand grand challenges and the role of entrepreneurial initiatives in the public and nonprofit sectors, as well as practitioners currently involved in collaborative efforts to address said challenges.Originality/valueThis study enriches the discussion and enhances the link between the CSSP literature and new notions of social entrepreneurship that embrace the collective as their unit of analysis. This is the first work of its kind to link bricolage to a nascent CSSP and demonstrate how the entrepreneurial concept of bricolage is an inherent part of CSSP formation and operation.
Clinical Outcomes in Burns Patients with Early Venous Thromboembolism Prophylaxis Compared with Late-Anticoagulated Patients: A Retrospective Study

The aim of this study was to describe the timing of venous thromboembolism diagnosis in patients with severe burns and determine the relationship between venous thromboembolism prophylaxis and venous thromboembolism development in a large trauma hospital. A retrospective cohort study over 10 years from 2009 to 2019 was conducted. Records of 226 patients with >20% total body surface area burns were surveyed, and 20 patients with symptoms suggestive of venous thromboembolism had a diagnosis of VTE confirmed on imaging. Enoxaparin was the most common primary thromboprophylaxis (85%, n = 192), followed by heparin (13.71%, n = 31) and sequential compression devices (0.88%, n = 2). Compared with patients who did not develop a venous thromboembolism, patients who developed a venous thromboembolism had a mean difference in time from admission to thromboprophylaxis prescription of 1.72 days (95% CI = −1.50 to 4.92, p > 0.05) and 10.51 days in those who developed a pulmonary embolus (mean difference = 10.51, 95% CI = 3.73 to 17.32, p = 0.0006). A threshold of 4 days was identified by which 96% of patients who never developed venous thromboembolism during admission were prescribed prophylaxis, compared with 32% of those who developed a pulmonary embolus. No bleeding or adverse events were recorded. Timely prescription of thromboprophylaxis in patients with severe burns is critical in reducing venous thromboembolism incidence. Avoidance of delay post injury is especially critical in preventing venous thromboembolism development. Guidelines on thromboprophylaxis must be considered on an individualised patient basis, considering likely surgical requirements and obesity.
In vitro antioxidant and antimicrobial activity of Prunus africana (Hook. f.) Kalkman (bark extracts) and Harrisonia abyssinica Oliv. extracts (bark extracts): A comparative study

Background: Plants are new sources of antibacterial agents, hence the need to determine and evaluate the antibacterial properties, antioxidant activity and gas chromatography – mass spectrometer (GC-MS) profile of medicinal plants. Methodology: In this study, sequential extraction of Prunus africana and Harrisonia abyssinica was used to obtain ethyl acetate and methanol extracts. Antioxidant activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), whereas the total phenolic and total flavonoid contents were estimated using Folin-Ciocalteu and aluminium chloride, respectively. Antibacterial properties of the extracts against Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coliand Candida albicans were estimated using the disc diffusion method and compared against streptomycin. Results: Screening of crude methanolic extracts revealed the presence of secondary metabolites which was further confirmed by Fourier transform infrared (FT-IR) characterisation that revealed the presence of H-bonded OH functional groups. The extracts revealed that P. africana had a higher total phenolic and total flavonoid contents compared to H. abyssinica. Methanolic extracts of both plants had moderate activity against selected microorganisms and both inhibited DPPH radical scavenging activity. GC-MS analysis of P. africana and H. abyssinica extracts revealed the presence of several phytochemicals that have been reported to have medicinal uses. Total phenolic and flavonoid contents showed positive correlations with the DPPH radical scavenging activity and negative correlations with EC50. Conclusion: Prunus africana and H. abyssinica extracts had moderate antimicrobial properties against the selected microorganisms because of the presence of secondary metabolites.
Low Temperature Synthesis of Elongated Triangular Bipyramidal ZnO Nanostructures for Photocatalytic Activity

The manuscript reports wet chemical assisted low temperature synthesis of CTAB stabilized elongated triangular bipyramidal shape nanostructures of ZnO for photocatalytic degradation of methyle blue (MB) and congo red (CR) dyes. Physiochemical characterization has been carried out by X-ray diffraction, scanning electron microscope, transmission electron microscope and UV-visible spectroscope. Pure wurtzite structure of ZnO with crystallite size ~56 nm has been confirmed from X-ray study. Well dispersed particles with elongated triangular bipyramidal morphology have been observed through SEM. Fine resolved particles with varied aspect ratios ~80 X 200 ± 10 nm have been depicted by TEM images. UV-visible absorption analysis confirms the energy band gap of 3.43 eV for synthesized ZnO particles. Molecular composition and functional groups of CTAB were confirmed by FTIR spectroscopy. The potential applicability of the particles for photocatalytic degradation of MB and CR as standard analytical dyes was studied. Time bound study under UV irradiated source depicted more than 95% degradation of both dyes in separate experiments.
A Link between Psychopathy Affect and Instrumentality in Homicide

This study tests the hypothesis that psychopathy is more associated with instrumental homicides than mixed and reactive homicides, and explores relationships between Psychopathy Checklist-Revised (PCL-R) facet/item scores and different forms of homicide: instrumental (n = 130), mixed (n = 103), and reactive (n = 219) homicides. Instrumental homicides scored higher on facet 2 (p < .01) but scored lower on facet 4 (p < .1) compared to reactive homicides, whereas no facet scores differed between mixed and reactive homicides. Among the items of facet 2 (affective), remorselessness (item 6), and callousness (item 8) were predictive of instrumental homicide.
RELATIONSHIP BETWEEN SECONDARY STUDENTS’ CRITICAL THINKING AND ACADEMIC ACHIEVEMENT: A CASE OF PUBLIC SCHOOLS

Purpose of the Study: The purpose of this research study was to study the relationship between critical thinking (CT) and academic achievement among secondary school students in a district of Gilgit-Baltistan. Methodology: Correlation design was applied to study the relationship between critical thinking and academic achievement. A sample of 400 students was selected through a convenient sampling technique to collect the data. Critical thinking was measured by applying an adapted tool (Sarigoz, 2012) and students’ scores in annual examinations were taken as academic achievement (York, Gibson & Rankin, 2015). Descriptive and inferential statistics were used to analyze the data. Main Findings: Findings of the study revealed that female students, rural school students, and science group students showed slightly higher critical thinking than male, urban, and arts group students. A markedly low positive relationship was found between critical thinking and academic achievement. The results were consistent with earlier studies having a positive relationship between these variables. There were also low and markedly low relationships found between constructs of critical thinking and academic achievement. Some results of this study were inconsistent with the earlier research based on the context of the students. The study revealed that there is a discrepancy in aligning critical thinking with academic achievement. Application of this study: The findings of the study help understand the relationship between critical thinking and academic achievement at the secondary level. It will surely assist the teachers in designing their classroom activities and modifications in teaching methodologies. It will boost the teachers to enhance the critical thinking of secondary school students. Novelty/Originality of this study: The study is original as not a single research study determined the relationship between critical thinking and academic achievement of secondary school students in the region of district Ghizar in Gilgit-Baltistan.
How farmer characteristics and dimensions of resilience correlate with farmers’ ability to recover from shocks: a case study of Indonesian palm oil smallholders

Most studies on the effects of certification on smallholders’ livelihood emphasize vulnerability while neglecting resilience. This paper assesses the farmer resilience of five different types of palm oil smallholders in Indonesia. We use and apply Speranza’s (2014) framework to assess and understand farmer resilience. We conclude that the correlations between buffer capacity, learning capacity, and resilience are rather weak. Our results further reveal that palm oil smallholders are relatively resilient to price declines, haze from forest fires and El Nino. The differences in resilience between the smallholder groups are small, although certified smallholders collaborating with companies and NGOs seem to be more resilient than uncertified smallholders collaborating with middlemen. The terminated Nucleus Estate Smallholder (NES) system allowed farmers to meet these favourable conditions. A few new initiatives, such as FAIR company-community partnerships may provide similar opportunities for smallholders. We also question the direct link between self-organization and resilience.
Grating Lobe Suppression of Sparse Phased Array by Null Scanning Antenna

A grating lobe suppression approach based on the null scanning antenna (NSA) for a sparse phased array is proposed. The NSA provides continuous null scanning and beam steering on two orthogonal planes, by connecting four varactor loaded impedance reconfigurable circuits to the four edges of a square patch antenna, respectively. The NSA is introduced into a sparse phased array and the grating lobe is suppressed by keeping the radiation pattern null of NSA pointing at the angle of the grating lobe during beam scanning. Meanwhile, the beam direction of NSA is steered to a wider angle with the variation of null angle. The main lobes during beam scanning are located within the 3 dB beamwidth of NSA. Thus, the sidelobe level (SLL) and scan loss over the wide scanning region are improved considerably. A $2\,\,\times \,\,4$ sparse phased array with NSA is designed and measured for verification. Both simulated and measured results indicate that the SLL of the sparse phased array with NSA can be suppressed below −9.3 dB within the scan range from −76° to 75°. The maximum realized gain during beam scanning is 17 dBi, with an aperture efficiency of 69.86% and a maximum gain fluctuation of 4.4 dB.
Quality of Life, Family Climate, and Sense of Family Coherence During the COVID-19 Pandemic: Modeling of Triple-Serial Mediators

This study explored the association of quality of life (QOL) during the pandemic with family climate and family integrity. Participants were 1085 parents from Turkey. According to the findings, the participants’ QOL, which demonstrated their judgments regarding their physical health, mental well-being, social relations, and general happiness, was greatly influenced by the COVID-19 pandemic. Women were seen to have lower perceptions in relatedness in the family and cognitive cohesion than male participants. While there was a positive, but low, association between the variables, there were positive and high correlations between cognitive cohesion and relatedness in the family. When the mediation analyses were evaluated, it was concluded that QOL predicted the sense of family coherence alone, while intergenerational authority influenced other variables. The results highlighted the importance of family climate–based prevention and intervention targeting the promotion of family coherence.
Analysis of the Internal Relationship between Ecological Value and Economic Value Based on the Forest Resources in China

In this study, we applied gross ecosystem product (GEP) theory in a case study to analyze and explain the natural resource asset value and ecosystem service value of forest resources in Jiaokou County, Shanxi Province, Northern China, in 2018. GEP refers to the total value of various final material products and services provided by ecosystems. In this paper, six service functions of a forest system, including water conservation, soil conservation, carbon fixation and oxygen release, forest nutrients, purification of atmospheric environment, and biodiversity, are valued by three calculation methods: the alternative cost method, market value method, and control cost method. The study revealed the following: (1) There is a parallel relationship between the value of natural resource assets and the value of ecosystem services. GEP includes the market value of natural resource assets, but it is mostly the value of ecosystem services. (2) The measurement of the physical quantity of forest ecosystem services depends on parameter data, and the monetary calculation often has no mature pricing basis, which leads to the large scale and uncertainty surrounding the evaluation results of ecosystem services. (3) The ecosystem service value and natural resource asset value have different practical significance, as well as alternate theoretical bases. The value of natural resource assets can be used as the asset valuation basis of economic transactions, which plays a role in macroeconomic management. The value of ecosystem services can be used as the basis of ecological compensation, providing information for the preparation of the balance sheet of natural resources.

Quitosano induce respuestas defensivas en plantas de soya inoculada con Bradyrhizobium elkanii

Chitosan is a natural polymer that induces numerous biological responses in many plant species, for instance, the induction of enzymatic and metabolic defense responses to biotic stress. In this paper, basal induced resistance enzymes (β 1-3 Glucanase, Chitinase and Phenylalanine-ammonia-lyase) and protein content, were determined in soybean organs, inoculated with Bradyrhizobium and growth in culture media added with different chitosan concentrations. Defensive response induced by the polymer depended on its concentration, the organ of the plant and the moment evaluated. The behavior of enzyme levels was different in soybean leaves and roots and inversely proportional to protein content. Enzymatic values in leaves were higher at 7 days post-treatment than at 21 days, except β 1-3 glucanase activity. However, in the roots, the increases occurred at 21 days, except chitinase activity. Higher concentrations (100, 500 and 1000 mg L -1 ) of chitosan increased the enzyme levels in roots, mainly at 21 days after inoculation with B. elkanii. Results show the possibility of using chitosaccharides for the induction of defensive responses in soybean against pathogens, without affecting the symbiotic process carried out with Bradyrhizobium elkanii .
Application of the nitrogen laser calibration system in LAASO-WFCTA

The nitrogen laser calibration system for the Wide Field of View Cherenkov Telescope Array (WFCTA) is one of the most important components of the Large High Altitude Air Shower Observatory (LHAASO). This calibration system is composed of three parts, including a highprecision 3D lifting and rotating platform (HiRoP), a nitrogen laser and the wide field of view Cherenkov telescope prototypes. The accuracy of the HiRoP is of great importance for the precise calibration of WFCTA since it controls the laser beam’s pointing direction. A home-made HiRoP was introduced and the measurements implies that the angular and lifting accuracies of HiRoP are better than 0.003° and 0.075 mm, respectively. Furthermore, the pulse energy stability of the nitrogen laser beam is another remarkably important factor. The nitrogen laser system with a wavelength of 337.1 nm located in a high-precision temperature and humidity’s controlling container, resulting in a pulse energy fluctuation less than 3 percent. Besides, the method of a standard zero point verification is employed to improve the long-term accuracy of the beam pointing direction.
