Scallions are a highly valued leafy vegetable and are enjoyed worldwide due to their appealing taste and nutritional benefits. A combination of short cultivation cycles and high market demand not only enhances food security but also offers a profitable opportunity for growers. In our study, we aim to evaluate the effect of increasing boron (B) applications, specifically 0, 0.2, 0.4, 0.8, 1.2, and 1.6 mM B supplied as boric acid (H₃BO₃) in the nutrient solution, on several key physiological and agronomic parameters in scallions. Results showed that the effects of increasing B levels on biomass production were insignificant, but the root fresh weight (FW) significantly decreased with all B levels. Higher B levels (1.2 and 1.6 mM) caused decreases of 22.9% and 29.6%, respectively. The effects of all B levels on photosynthetic pigment contents [chlorophyll (Chl) a, b, a + b, and carotenoid (Car)], root and shoot membrane permeability (MP), and root, shoot, and leaf nutritional status [phosphorus (P), potassium (K), calcium (Ca), and sodium (Na) concentrations] were found insignificantly. However, all B levels caused a significant increase in the B concentrations of the root, shoot, and leaf of scallions and plants translocated the majority of applied B into their leaves. The translocation factor (TF) of B from the root to the leaf was found to be 138.2%, 133.3%, and 107.3% with 0.8, 1.2, and 1.6 mM B levels, respectively. Moreover, plants exposed to high levels of B showed no significant response or toxicity symptoms. We concluded that B is a phloem mobile element in onion, a non-graminaceous monocotyledonous plant, and therefore accumulates in the upper organs but illustrates partial toxicity symptoms in leaves. Studies with higher B concentrations could be recommended to determine critical B levels for green onion production in B-contaminated areas. Full article

This study evaluated the healthiness of meat products (n = 62) and their plant-based (PB) counterparts (n = 62) available in the UK market. Back-of-pack (BoP) and front-of-pack (FoP) nutrition label information, nutrition and health claims, and nutrient profiling model scores were compared. BoP labels revealed that meat products had higher protein, fat, and saturated fat content (p = 0.029), whilst PB alternatives were higher in dietary fibre and carbohydrates (p < 0.001). Red colour coding (FoP) for fat and saturated fat (‘high’) was more prominent in meat products (23 and 35%, respectively), and the red meat category had the most products with high fat and saturated fat content. Only 15% of meat products made nutrition claims compared to 40% of PB alternatives, and none included health claims. Most red meat PB alternatives made a nutrition claim, all related to the protein content (34%). The nutrient profiling model indicated that 74% of the PB alternatives were ‘healthy’ compared to 60% of the meat products. No association was found between the product type (meat/PB) and healthiness, except for the red meat products, which showed a significant negative association (p = 0.005), suggesting that these products corresponded to less healthy options. Therefore, PB alternatives can be considered as healthier substitutes for meat products. Full article

With retailers increasingly adopting the omnichannel retailing model as a core strategy in their daily operations, this study investigates the impact of random demand on the omnichannel supply chain that employs a combination of the online channel, retail channel, and buy online and pick up in store (BOPS) channel, in light of the more stochastic market after the occurrence of COVID-19. To enhance the sustainable profitability of the omnichannel supply chain, this study considers price and lead time dependent demand with both known and unknown distributions, and establishes mathematical models to maximize profit under centralized situations. The study analyzes the variations in demand with lead time in the three channels and examines the effects of price and lead time on profit. Additionally, it investigates the interactions between price and lead time. Through numerical examples, the study illustrates the effects of the mean and variance of random demand on decision variables and examines the influence of potential demand and the sensitivity of lead time. Overall, this analysis provides valuable insights into the impact of demand randomness on the profitability of an omnichannel supply chain, highlighting the importance of considering price and lead time in the decision-making process.

The clarity of the beer is essential to its marketability and good consumer approval. Moreover, the beer filtration aims to remove the unwanted constituents that cause beer haze formation. Natural zeolite, an inexpensive and widespread material, was tested as a substitute filter media for diatomaceous earth in removing the haze constituents in beer. The zeolitic tuff samples were collected from two quarries in Northern Romania: Chilioara, in which the zeolitic tuff has a clinoptilolite content of about 65%, and the Valea Pomilor quarry, containing zeolitic tuff with a clinoptilolite content of about 40%. Two-grain sizes, <40 and <100 µm, from each quarry were prepared and thermally treated at 450 °C in order to improve their adsorption properties and remove organic compounds and for physico-chemical characterization. The prepared zeolites were used for beer filtration in different mixtures with commercial filter aids (DIF BO and CBL3) in laboratory-scale experiments, and the filtered beer was characterized in terms of pH, turbidity, color, taste, flavor, and concentrations of the major and trace elements. The results showed that the taste, flavor, and pH of the filtered beer were generally not affected by filtration, while turbidity and color decreased with an increase in the zeolite content used in the filtration. The concentrations of Na and Mg in the beer were not significantly altered by filtration; Ca and K slowly increased, while Cd and Co were below the limits of quantification. Our results show that natural zeolites are promising aids for beer filtration and can be readily substituted for diatomaceous earth without significant changes in brewery industry process equipment and protocols for preparation.

This study evaluated the effects of hanging the carcass by the Achilles tendon (AS) versus pelvic suspension (PS) on meat quality traits. Bos indicus carcasses of two distinct biological types/sex categories comprised 10 young Brangus heifers and 10 Nellore bulls which were finished in a feedlot. Half-carcasses of each biological type/sex category were randomly hung using Achilles suspension (n = 20, AS) or pelvic suspension (n = 20, PS) for 48 h. At boning, longissimus samples were collected for evaluation by untrained consumers for tenderness, liking of flavor, juiciness and overall acceptability, after aging for 5 or 15 days. Objective samples were also tested for shear force (SF), Minolta meat colour, ultimate pH, cooking loss (CL) and purge loss (PL). There was a positive effect (p < 0.01) of PS on the sensory tenderness of Nellore bulls and Brangus heifers aged for 5 days compared to the AS method. At 15 days of aging, difference in sensory tenderness was observed (p < 0.05) in either group. Additionally, an interaction occurred between the suspension method and the aging of Nellore beef (p < 0.05) on liking of flavor, juiciness and overall acceptance, while the same effects were not observed for Brangus beef (p > 0.05). Nellore carcasses submitted to PS tended (p = 0.06) to produce more tender meat than those submitted to AS (SF = 44.62 ± 6.96 vs. 50.41 ± 8.04 N), and lower CL (p < 0.05) were found (27.7 vs. 30.9%). Carcass-suspension methods did not influence meat color, pH or PL in either group (p > 0.05). The PS contributes to improve the quality of Bos indicus bulls loins; in addition, this method allows a reduction in the aging time from 15 to 5 days, and it can be used to supply meat consumer markets which accept a certain level of eating quality.

The objective of this study is to review and synthesize entrepreneurship in the context of the bottom/base of pyramid (BoP). The concept of the BoP approach, which describes the possibility of profitably in both serving the poor and alleviating poverty, has iterated from 1.0 to 3.0 since 2002. It has transformed from engaging the poor as “customers” (BoP 1.0) to engaging them as “producers” (BoP 3.0). However, although the poor in BoP markets perform as active, central focal actors to identify and create entrepreneurial opportunities, inadequate attention has been paid to the question of how to engage the poor as entrepreneurs. Understanding this question is critical because entrepreneurship has been regarded as an effective tool to relieve poverty. Therefore, this research focuses on three specific questions: (1) What are the characteristics of entrepreneurs in the BoP market? (2) What are the contents of their entrepreneurial activities? and (3) What are the consequences? To answer these questions, this paper conducted a systematic literature review of 56 studies on entrepreneurship at the BoP in the scientific database Web of Science by using PRISMA to guide the review process. From the findings of the three research questions, the study also further identifies four types of entrepreneurs at the BoP (i.e., survival entrepreneurs, community entrepreneurs, professional entrepreneurs, and full entrepreneurs). With a discussion on future directions for these four types of entrepreneurs, this review highlights the heterogenous roles of the poor at the BoP and their challenges to create wealth, which is beneficial for directing the focuses of this topic.

Many Kenyan base-of-the-pyramid (BoP) consumers—defined as the poorest two-thirds of the economic human pyramid—remain food insecure, despite the availability of nutrient-dense foods in the market. This study reveals how effective marketing strategies can strengthen food security among BoP consumers through increased access to nutritious foods such as nutrient-dense porridge flour. Nutrient-dense porridge flour refers to a multi-composite porridge flour composed of diverse nutritious ingredients that are necessary to achieve a healthy diet. The main objective of the study was to determine the most effective channel for making nutrient-dense porridge flour available to BoP consumers. Data were collected through a cross-sectional survey in Kawangware, Nairobi County, using a multistage sampling design and a sample size of 603, via structured questionnaires. A multivariate Probit (MV-Probit) model was used to analyze the most effective channel for providing nutrient-dense flour to BoP consumers. The study results show that the most common outlets used to access this flour were supermarkets (51.08%), followed by cereal stores (25.54%). According to previous studies, using appropriate marketing strategies leads to increases in the uptake and consumption of nutritious products in informal urban settlements among developing countries. Consequently, policies and interventions targeting BoP consumption of nutritious products toward reducing food and nutrition insecurity in informal urban settlements should be based on appropriate marketing strategies that consider the institutional factors and significant household characteristics of the BoP communities.

In recent years, implantology has made significant progress, as it has now become a safe and predictable practice. The development of new geometries, primary and secondary, of new surfaces and alloys, has made this possible. The purpose of this review is to analyze the different alloys present on the market, such as that in zirconia, and evaluate their clinical differences with those most commonly used, such as those in grade IV titanium. The review, conducted on major scientific databases such as Scopus, PubMed, Web of Science and MDPI yielded a startling number of 305 results. After the application of the filters and the evaluation of the results in the review, only 10 Randomized Clinical Trials (RCTs) were included. Multiple outcomes were considered, such as Marginal Bone Level (MBL), Bleeding on Probing (BoP), Survival Rate, Success Rate and parameters related to aesthetic and prosthetic factors. There are currently no statistically significant differences between the use of zirconia implants and titanium implants, neither for fixed prosthetic restorations nor for overdenture restorations. Only the cases reported complain about the rigidity and, therefore, the possibility of fracture of the zirconium. Certainly the continuous improvement in these materials will ensure that they could be used safely while maintaining their high aesthetic performance. Full article

An important market that is receiving increasing attention by firms relates to the poorest at the Base of the Pyramid (BoP). BoP businesses contribute to the first UN Sustainable Development Goal that calls for an end to poverty in all its manifestations. BoP businesses are regarded as financially and socially beneficial for both participating firms and poor communities. It is, however, understood that success in BoP markets cannot (and should not) be assumed, as it demands a profoundly different view towards managing supply chains. Focusing on this issue, our conceptual study contributes to the emerging debates in BoP and supply chain management research by elaborating the notion of legitimacy contexts (LCs) at BoP. We draw on institutional theory to characterize the LCs in BoP markets and discuss their implications for key supply chain functions. We argue that firms often design their supply chain functions for BoP business using their own LCs as opposed to those of BoP actors. This implies ignoring the institutional distance between BoP markets and firms and reveals a key culprit in the failure of BoP projects. We offer practical implications for firms intending to engage in BoP business. Full article

It is important for companies to be able to make their business models dynamic. This enables them to adapt to changing circumstances and remain viable. The aim of this paper is to combine insights from the literature on business models and business model dynamics into a comprehensive dynamic business model framework. The framework that is developed in this paper takes into account various origins of changes in business models (internal or external to the company) and various types of changes in business models (primary or secondary changes and forced changes or strategic choices) and also includes the issue of business model consistency. In order to combine different origins and different types of business model change into one dynamic business model framework, some simplifications of reality were needed. The framework is described in text and shown in a comprehensive picture. The application of the framework to two cases of renewable energy companies in Indonesia shows that the framework is able to capture business model dynamics in a simplified and comprehensive way and that it allows for case study comparison. In a thorough discussion, it is shown how the framework can be adapted to make it better able to represent more complex dynamics. Full article

The main research question asked in this paper is whether and when a dual-channel retailer (retailer in short) should adopt the “buy online and pick up in store” (BOPS) strategy. To answer this question, we first derive the optimal price decision using the non-BOPS and BOPS strategies. Subsequently, we compare the performance of retailers under non-BOPS and BOPS scenarios. Our main findings are that under the monopoly scenario, retailers may not always benefit from the BOPS strategy. Retailers will benefit only if the offline operational costs are low and the degree of customer acceptance of the online channel is high. However, the BOPS strategy cannot improve dual-channel retailers’ market share. Furthermore, under a Stackelberg game scenario with e-retailers as leaders, when the value of a product is medium and the transaction costs of the offline channel are high, retailers can use the BOPS strategy to enhance their market share. If the degree of customer acceptance of the online channel is also high, retailers can further improve their profits by using the BOPS strategy. Overall, these findings not only provide decision support for retailers, but also enrich the theories on dual-channel retailing in operations management. Full article

Rural e-commerce entrepreneurship is an effective and credible means to alleviate poverty and promote sustainable social development, particularly in the Base of the Pyramid (BoP). Understanding how to encourage BoPs’ entrepreneurial intention in the rural e-commerce market has become a key issue for private enterprises and local governments. Based on the entrepreneurial event model, we constructed a research framework to evaluate the factors influencing BoPs’ entrepreneurial intention in rural e-commerce. We conducted an online survey of rural e-commerce practitioners from Jieyang and Chaozhou in Guangdong Province, China, and empirically analyzed the survey results using SmartPLS software. The results show that professional knowledge, resource endowment, information and communication technology, and logistics infrastructure have a significant positive impact on BoP entrepreneurship in rural e-commerce, while previous market channels had a significant negative impact. Based on the findings, we recommend that BoPs should focus more on cultivating professional knowledge in e-commerce entrepreneurship and capitalize on local resource advantage. E-commerce enterprises and local governments should strengthen and improve information communication technology and logistics infrastructure among BoP communities. Policymakers should support BoP entrepreneurship in rural e-commerce by creating a favorable environment. Full article

The Bottom of the Pyramid (BOP) market is composed of a large number of low-income groups around the world and contains huge wealth that has not yet been discovered. An exploratory multi-case study was conducted to analyze the impact of relational embeddedness on dynamic capability (DC). On the basis of theoretical presuppositions, based on the intra- and inter-case analysis of six companies in the China BOP market, this paper explores how relational embeddedness affects the DC of companies through exploitative learning and exploratory learning. Twelve research propositions are presented and the theoretical framework of relational embeddedness affecting the DC of enterprises is constructed. The study found that mutual trust and reciprocity norms in the BOP cooperation network can promote the acquisition and utilization of existing knowledge and new knowledge of the enterprise, thereby enhancing the enterprise environmental sensing, environmental adaptive, and environmental shaping capabilities.

Enterprises operating at the Base of the Pyramid (BoP) find it difficult to simultaneously achieve economic (profitable growth) and social (poverty alleviation) outcomes. This study builds on a previously published systematic literature review that identified the key growth-promoting factors of the Small, Medium, and Micro Enterprises (SMMEs) operating in this space. A Grounded Theory Approach was followed to identify six core focus areas, which form the basis of a practical framework to evaluate SMMEs at the BoP, namely: Business modelling; business strategy; innovation; marketing; strategic alliances; and sustainable development. Expert screening interviews were conducted to evaluate the framework for credibility and confirmability. Thereafter, 57 for-profit South African enterprises were surveyed to empirically explore how SMMEs view and implement these framework components. The outcome of the study is a validated high growth-promoting BoP portfolio framework against which SMME owners can evaluate their enterprises to identify areas of growth and development.

Co-creation with the population at the Bottom of the Pyramid (BOP) was identified as pivotal for realizing the full potential of the BOP proposition, simultaneously creating economic value for companies in BOP markets, as well as social value for the individuals residing in them. However, research on co-creation and its outcomes has remained predominantly simplistic, often assuming that introducing any form of co-creation in company operations will lead to increased social value and economic gains. A more nuanced exploration of the different ways in which companies operationalize the principle of co-creation across their supply-chain and whether these indeed facilitate such a clear win-win scenario for both parties, remains relatively scarce. In this paper we address this gap and delve into the supply chains of 135 micro, small, and medium sized ventures operating in BOP markets. We identify four overarching patterns of co-creation and ten categories of specific practices used to achieve them, and ultimately show how these patterns facilitate very different levels of social sustainability and economic benefits across the supply chain.
