    Purpose This paper aims to investigate the applicability of Grant’s framework in the current changing and dynamic environment. Design/methodology/approach In this paper, a critical review of Grant’s paper was conducted to identify the limitations and weaknesses of the framework, which prevent its effective application in the current digital age. Findings As a result, this paper presented a modified framework and four propositions to consider dynamic capabilities in the new turbulent environment and extend the relationships between a firm’s resources, capabilities, dynamic capabilities, competitive advantage and competitive strategy. Findings tied to this initiative will provide important contributions to research. Originality/value Rooted in resource-based view (RBV), the proposed framework puts forward a valid theoretical foundation on how to create a competitive advantage from a firm’s internal factors, including strategic resources, capabilities and dynamic capabilities. Furthermore, it contributes to RBV literature by considering dynamic capabilities, as the firms’ most crucial factors in the current dynamic digital market

    Main message: The overall interplay between competitive strategies and dynamic capabilities is an integral part of value creation in terms of novelty, lock-in, complementarities and efficiency. Short title: Competitive strategy, dynamic capability and value creation Key points: -In response to insufficient systematic research on the impact of competitive strategies and dynamic capabilities on value creation, this study expands prior studies (e.g., Rashidirad et al., 2013) by proposing carefully testable research hypotheses and empirically explore the research phenomenon. -This study analyses the complex interrelationships between competitive strategies and dynamic capabilities and the resulting impact on value creation through adopting a multidimensional approach in which each construct is decomposited to its dimensions, so the relationships between each dimension of the research constructs are investigated. -This study prompts rethinking of the impact of dynamic capability and competitive strategy on value creation in firms by using a multidimensional perspective

    Effects of Sucrose, Skim Milk and Yeast Powder on Survival of Lactobacillus rhamnosus GG Encapsulated with Alginate during One-week Storage at room Conditions

    Background and Objective: During the manufacture and storage of probiotic products, there are always possibilities that probiotics be exposed to harmful stresses such as high temperature, low pH, various osmotic pressures and high oxygen levels, which can decrease the number of living cells. Encapsulation is one of the methods used to protect living cells such as probiotic bacteria from environmental challenges. Up-to-date, various compounds with abilities to protect bacteria during freeze-drying and to increase viability during storage have been identified. In this study, alginate with calcium chloride was used to encapsulate probiotic bacteria using extrusion method. Then, effects of sucrose and skim milk as cryoprotectants and yeast powder containing beta-glucan as prebiotic on the survival of these bacteria were investigated. Material and Methods: The Homogeneous solution of bacteria with alginate and cry protectants were manually extruded into a calcium chloride solution. After 30 min of agitation, shaped beads were separated. For the comparison, bacterial population were enumerated in the primary culture, after encapsulation, freeze-drying and 1 week of storage at room conditions (N0, N, NF and N1w, respectively). To assess colony-forming unit per ml of the samples, first 1 g of fresh beads was dissolved in 9 ml of trisodium citrate and then serial dilution and pour plate techniques were carried out. Plates were incubated for 24-48 h and colonies were counted. Results and Conclusion: Results showed that encapsulation of bacteria with alginate and calcium chloride alone was 51% effective while use of yeast powder and sucrose with alginate increased the encapsulation efficiency to 97 and 99%, respectively. Furthermore, use of skim milk with alginate and sucrose resulted in the highest survival rate after 1 week of storage at room conditions. Therefore, encapsulation of probiotic bacteria with alginate layer and yeast powder containing prebiotics, sucrose and skim milk can be effective in survival of these bacteria.

    A contingency view to novelty: The role of product-service strategy, sensing capability and environmental turbulence

    Get PDF
    Purpose: The aim of this study is to examine (i) the impact of the fit between product-service strategy and sensing capability on novelty, and (ii) the potential moderating impact of contextual factors (i.e. technological and market turbulence) on novelty. Design/methodology/approach: In line with the aim of the study, a quantitative approach was adopted and a multi-item scale survey was designed to collect primary data. Using a mixed mode survey, a total number of 491 questionnaires were collected from a sample of UK-based telecommunications firms. Multiple regression was employed to test the hypotheses and predict the outcomes. Findings: The results support the positive contribution of a contingency approach to the study of the impact of the fit between product-service strategy and sensing dynamic capability on novelty. The results also partially confirm the reinforcing impact of technological and market turbulence on novelty. Originality/value: The current study extends research on product-service strategy and sensing capability by adopting a contingency view which intends to serve two purposes: (i)to complement the existing reductionistic explanations, and (ii) to explore how the relationship between product-service strategy and sensing capability could create novelty as well as the degree to which this relationship could be moderated in light of the external contextual factors

    Supplier quality management and performance: the effect of supply chain oriented culture

    Get PDF
    Drawing from contingency theory, we investigate the impact of Supplier Quality Management (SQM) activities on internal quality performance and examine the role of Supply Chain Oriented (SCO) culture in the relationship between SQM and internal quality performance. A survey-based research was designed to collect data from 518 UK manufacturing firms. The results indicate that organisations with strong SCO culture are more conducive to increased levels of trust, commitment, cooperative norms, organisational compatibility and managerial support. As such, effective supplier development and integration activities appear to bring about a higher level of internal quality performance. The results also support the moderating effect of SCO culture on the relationship between supplier quality management and internal quality performance. The study highlights the importance of SCO culture – if organisations want to optimise internal quality and organisational performance in a sustainable manner through effective buyer-supplier relationships. This study contributes to the literature by analysing SQM and internal quality performance relationships through the lens of contingency theory and presents empirical evidence in support of the context dependency nature of SQM and its impact on performance. In this respect, a contextual variable theorised as ‘SCO culture’ is conceptualised to understand the SQM – performance relationship

    Background: Herbal medicines are the preferred anticancer agents due to their lower cytotoxic effects on healthy cells. Plant lignans play an important role in treating various diseases, especially cancer. The present study aimed to evaluate the effect of podophyllotoxin, pinoresinol, and lariciresinol on cellular toxicity and inducing apoptosis in fibroblasts, HEK-293, and SkBr3 cell lines.Methods: An in vitro study was conducted from 2017 to 2019 at the Faculty of Biological Sciences, Tarbiat Modares University (Tehran, Iran). The cell lines were treated for 24 and 48 hours with different concentrations of lignans. Cell viability and apoptosis were examined using MTT and flow cytometry, respectively. Expression levels of cell cycle and apoptosis regulator genes were determined using quantitative real-time polymerase chain reaction. Data were analyzed using a two-way analysis of variance followed by Tukey’s HSD test. P<0.05 was considered statistically significant.Results: Podophyllotoxin significantly increased apoptosis in fibroblast cells compared to pinoresinol and lariciresinol (P<0.001). The percentage of cell viability of fibroblast cells treated for 48 hours with pinoresinol, lariciresinol, and podophyllotoxin was reduced by 49%, 47%, and 36%, respectively. Treatment with pinoresinol and lariciresinol significantly overexpressed pro-apoptotic genes and underexpressed anti-apoptotic genes in SkBr3 cells (P<0.001). SkBr3 cells treated with lariciresinol significantly reduced gene expression (P<0.001). Conclusion: Pinoresinol and lariciresinol can potentially be used as new therapeutic agents for the treatment of breast cancer

    A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic

    Measuring universal health coverage based on an index of effective coverage of health services in 204 countries and territories, 1990–2019 : A systematic analysis for the Global Burden of Disease Study 2019

    Background Achieving universal health coverage (UHC) involves all people receiving the health services they need, of high quality, without experiencing financial hardship. Making progress towards UHC is a policy priority for both countries and global institutions, as highlighted by the agenda of the UN Sustainable Development Goals (SDGs) and WHO's Thirteenth General Programme of Work (GPW13). Measuring effective coverage at the health-system level is important for understanding whether health services are aligned with countries' health profiles and are of sufficient quality to produce health gains for populations of all ages. Methods Based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we assessed UHC effective coverage for 204 countries and territories from 1990 to 2019. Drawing from a measurement framework developed through WHO's GPW13 consultation, we mapped 23 effective coverage indicators to a matrix representing health service types (eg, promotion, prevention, and treatment) and five population-age groups spanning from reproductive and newborn to older adults (≥65 years). Effective coverage indicators were based on intervention coverage or outcome-based measures such as mortality-to-incidence ratios to approximate access to quality care; outcome-based measures were transformed to values on a scale of 0–100 based on the 2·5th and 97·5th percentile of location-year values. We constructed the UHC effective coverage index by weighting each effective coverage indicator relative to its associated potential health gains, as measured by disability-adjusted life-years for each location-year and population-age group. For three tests of validity (content, known-groups, and convergent), UHC effective coverage index performance was generally better than that of other UHC service coverage indices from WHO (ie, the current metric for SDG indicator 3.8.1 on UHC service coverage), the World Bank, and GBD 2017. We quantified frontiers of UHC effective coverage performance on the basis of pooled health spending per capita, representing UHC effective coverage index levels achieved in 2019 relative to country-level government health spending, prepaid private expenditures, and development assistance for health. To assess current trajectories towards the GPW13 UHC billion target—1 billion more people benefiting from UHC by 2023—we estimated additional population equivalents with UHC effective coverage from 2018 to 2023. Findings Globally, performance on the UHC effective coverage index improved from 45·8 (95% uncertainty interval 44·2–47·5) in 1990 to 60·3 (58·7–61·9) in 2019, yet country-level UHC effective coverage in 2019 still spanned from 95 or higher in Japan and Iceland to lower than 25 in Somalia and the Central African Republic. Since 2010, sub-Saharan Africa showed accelerated gains on the UHC effective coverage index (at an average increase of 2·6% [1·9–3·3] per year up to 2019); by contrast, most other GBD super-regions had slowed rates of progress in 2010–2019 relative to 1990–2010. Many countries showed lagging performance on effective coverage indicators for non-communicable diseases relative to those for communicable diseases and maternal and child health, despite non-communicable diseases accounting for a greater proportion of potential health gains in 2019, suggesting that many health systems are not keeping pace with the rising non-communicable disease burden and associated population health needs. In 2019, the UHC effective coverage index was associated with pooled health spending per capita (r=0·79), although countries across the development spectrum had much lower UHC effective coverage than is potentially achievable relative to their health spending. Under maximum efficiency of translating health spending into UHC effective coverage performance, countries would need to reach 1398pooledhealthspendingpercapita(US1398 pooled health spending per capita (US adjusted for purchasing power parity) in order to achieve 80 on the UHC effective coverage index. From 2018 to 2023, an estimated 388·9 million (358·6–421·3) more population equivalents would have UHC effective coverage, falling well short of the GPW13 target of 1 billion more people benefiting from UHC during this time. Current projections point to an estimated 3·1 billion (3·0–3·2) population equivalents still lacking UHC effective coverage in 2023, with nearly a third (968·1 million [903·5–1040·3]) residing in south Asia. Interpretation The present study demonstrates the utility of measuring effective coverage and its role in supporting improved health outcomes for all people—the ultimate goal of UHC and its achievement. Global ambitions to accelerate progress on UHC service coverage are increasingly unlikely unless concerted action on non-communicable diseases occurs and countries can better translate health spending into improved performance. Focusing on effective coverage and accounting for the world's evolving health needs lays the groundwork for better understanding how close—or how far—all populations are in benefiting from UHC
