Managing internationalisation tensions in producer cooperatives
Cooperatives, an important part of Oceania’s economies, are attracting renewed interest as an organisational form for addressing societal challenges. Yet that mission often depends on growth and internationalisation strategies, which introduce multiple tensions that can lead to an erosion of cooperative principles. How cooperatives can successfully manage such tensions arising from internationalisation has been understudied by IB scholars. Our study of Zespri shows that the transfer of cooperative principles is possible when internationalisation is viewed as an incremental process of learning and active managerial agency aimed at reconciling competing logics.Peer reviewe
Metaorganizing collaborative innovation for action on Grand Challenges
Grand Challenges are complex issues that require collaborative innovation among heterogeneous actors who draw upon contradictory institutional logics. While existing literature shows how social enterprises and individual organizations reconcile tensions between economic and environmental logics, scholars know less about how and when a broad set of actors adopt practices and priorities that balance economic and environmental values. This article explores how three agricultural cooperatives act as metaorganizations and facilitate collaborative innovation and sustainable transitions to address grand challenges regarding land use. We find that the cooperatives stimulate awareness of environmental challenges and local experimentation, orchestrate collaborative solutions by enrolling and engaging a broad set of actors, and coordinate the diffusion of novel practices across the institutional field. We add new insights into producer cooperatives' role as metaorganizations in facilitating the creation, validation, and diffusion of practices that balance business and sustainability. Based on our findings, we argue that by metaorganizing, producer cooperatives can galvanize field-level shifts in institutional logics through framing, knowledge sharing, and knowledge brokering mechanisms.Peer reviewe
Influence of Low-Level Laser Modification and Adhesive Application Mode on the Bonding Efficiency of Universal Adhesives to Er:YAG Laser-Ablated Dentin
Introduction: Erbium laser ablation as a method of tooth preparation and conditioning has shown promising results. Although previous studies have adopted various combinations of different laser parameters and several dentin adhesive systems, very few have investigated combining high-level and low-level Er: YAG lasers with Universal adhesives. This study aimed to assess the impact of using low-energy irradiation on the surface micro-topography and shear bond strength (SBS) of universal adhesive (UA) to the erbium:yttrium-aluminum-garnet (Er: YAG) laser-ablated dentin substrate, bonded in etch-and-rinse or self-etch adhesive mode.Methods: Eighty-seven extracted molars were sectioned to expose flat occlusal dentin surface; 60 teeth were divided equally into three groups according to the surface treatment; bur-cutting (B), Er: YAG high-energy laser cutting, or L1 followed by low-energy laser modification. Then each group was equally divided into two groups (n=10) according to the mode of application of the universal adhesive; either etch-and-rinse (ER) or self-etching (SE). The samples were subjected to thermocycling (5000 cycles between 5°C and 55°C), and SBS was tested. Two-way ANOVA and Tukey post hoc test was used to analyze the results. The remaining 27 samples were used to investigate the effect of the treatment on the topography of the treated dentin surfaces using a scanning electron microscope (SEM).Results: B/SE recorded the highest SBS (25.48 ± 2.6 MPa) followed by B/ER and L1/L2/SE (22.94 ± 4.1 MPa) and with no statistically significant difference between these groups (P >0.05). The lowest SBS results (P<0.05) were recorded for L1/SE (12.22 ± 3 MPa). No statistical differences were found between the SBS of L1/L2/ER and L1/ER groups or between the SBS of L1/L2/ER and L1/L2/SE groups.Conclusion: A subsequent treatment of the Er: YAG laser-ablated dentin with low-energy laser modification mode (LMM) enhances the SBS of the tested UA when applied in SE mode.

Threading the needle of the digital divide in Africa,T he barriers and mitigations of infrastructure sharing
Coopetition is prevalent in today's dynamic business environment and has attracted research interests. Using coopetitive-based view, this study examines the antecedents and drivers of infrastructure sharing (IS) among local and multinational mobile network operators (MNOs) in Africa. Based on 21 interviews with different stakeholders in seven sub-Sahara African (SSA) countries, we develop an integrative framework of industry/market, technological, and institutional factors that affect IS between MNOs. We find evidence of institutional factors shaping the impact of the industry structure and technological factors on firms’ propensity to engage in coopetitive strategies. There is evidence that in contexts with low-level IS, inadequate regulatory interventions mean that the existing market conditions are reproduced, leading to further competitive behaviours from MNOs. For high- level IS, MNOs tend to engage in further coopetitive strategies through strategic learning and cooperate to resolve technological incompatibilities and engage in standards settings. We extend the existing scholarly works on coopetition and IS literature by providing an in-depth understanding of the obstacles faced by MNOs in adopting IS. The study further highlights that IS requires a shift from the competitive-based logic to a dynamic, coopetitive one, which is nonetheless challenging to achieve with limited institutional capacity and support
Some Ecological Aspects on the Striped Mealybug Ferrisia virgata (Cockerell) Infesting Acalypha Shrubs in Qalyubiya Governorate, Egypt
Acalypha shrubs Acalypha wilkesiana Mull.(Euphorbiaceae) found to be favorable host for the striped mealybug Ferrisia virgate (Cockerell)( Pseudococcidae) . This mealybug species is attacked all plant parts and caused considerable damages to this host. Some ecological aspects were carried out on F. virgata infesting acalypha shrubs throughout two successive years (2014-2015) and (2015-2016) in Qalyubiya Governorate. Results obtained showed that population density was more abundant during the second year than the first one, the annual means of total population were 62.02 and 52.01 individuals/leaf), respectively. Also, results revealed that, seasonal abundance of F. virgata found to be active from June to January of next year. The population density was reached its maximum activity on October during both years being 123.0 and 145.2 individuals /leaf for the first and second year, respectively. The prevailing main average temperature and relative humidity were ranging between 22.8°C, 24.2°C and 67%, 64% for the 1st and 2nd years, respectively. These conditions seemed to be favorable conditions for insect activity. After this activity period all stages of this species were disappeared from all plant parts. This phenomenon indicate that this mealybug species was overwinter during winter and spring seasons till the next summer. From these findings it could be stated that any control measurements must be early applied during June, at the beginning of activity period of this mealybug species. Also, results clarified that F. virgate was passed through two annual overlapping field generations on acalypha shrubs. Duration of the first generation was ranged between 80-85 days which occurred during summer months. While the second generation was lasted 75 days and occurred during autumn. Statistical analysis revealed that separate effect of each mean, two weeks earlier of the four selected weather factors on changes in population density of F. virgata most factors had insignificant effects except mean minimum temperature which had positive significant effects throughout the both years (r coefficient values were 0.589 and 0.677). While the combined effects of the four selected factors (mean minimum, maximum temperature, average temperature and mean percentage of relative humidity), two weeks earlier, had significant effects, as a group on the change in population density especially during (2014-2015) , the explained variance was 79.2% and F value 14.4

Building green innovation networks for people, planet, and profit: A multi-level, multi-value approach
In this conceptual paper we explore the problem of how firms balance profit considerations against their contribution to society and the environmental. We theorize how firms build networks that support green transition, enabling them to reconfigure processes that match sustainability goals and maintain profitable. We explore how building networks for green transition supports firms\u27 transition to more sustainable approaches that support the adoption of, and transition to, green strategies. We extend current theorization of how firms build multi-level B2B networks that support green transition that benefits society and the environment. We suggest three propositions that support the development of a multi-level, multi-value model for building green innovation networks. We identify four critical success factors - embedding technological diversity, developing knowledge sharing mechanisms, embracing open innovation strategies, overcoming resistance to change, − that support this process and help firms overcome value creation frictions and deliver multi-value benefits to society (people) and the environment (planet), whilst enabling firms to make a profit. Our conclusion outlines our contribution and highlights areas for future research
