- Purpose: Vitrectomy requires the substitution of the natural vitreous, as well as tamponading of retinal breaks. Clinically available alternatives such as gas and silicone oil have side effects such as inflammation, secondary glaucoma, cataract, and a need for head posturing. In this study, a hydrogel of cross-linked sodium hyaluronic acid (Healaflow(®)) is evaluated for use as a novel vitreous substitute.Methods: A combined 25-20-gauge pars plana vitrectomy with posterior vitreous detachment was performed in the right eye of twelve pigmented rabbits, with subsequent injection of approximately 1 ml Healaflow(®). Clinical evaluation, measurement of intraocular pressure (IOP), and full-field ERG were performed postoperatively. The rabbits were sacrificed at different time-points between 42 and 105 days. After enucleation, the eyes were examined macroscopically, photographed, and prepared for histological examination with routine microscopy and immunohistochemistry.Results: Healaflow(®) was successfully used with standard surgical procedures and remained translucent but did lose most of its viscosity during the postoperative period. One rabbit was lost due to unrelated causes. In two eyes iatrogenic partial retinal detachments were seen, and in two eyes significant cataract developed due to intra-operative complications. ERG-recordings revealed no toxic effect on rod or cone function. Routine microscopy and immunohistochemistry demonstrated normal morphology with some Müller cell activation (up-regulation of glial acidic fibrillary protein, GFAP) compared to unoperated eyes and no significant DNA-fragmentation (TUNEL-assay).Conclusions: Healaflow® did not affect retinal morphology or function negatively during long-term use as a vitreous substitute, making it highly interesting in this setting. An estimated retention time of a few weeks suggests potential for use as a short-term tamponade. Future work will include an increased ratio of cross-linking to prolong the structural integrity of the gel.

Tidskriftsartikel (refereegranskat)abstract
- Increased global competition in the agricultural sector is rapidly changing the structure of farms and farming. As the number of small and diversified farms (often family-owned) decreases, the number of large and specialized farms (often corporate-owned) is increasing. In this transformation, the agricultural sector is more and more concerned with strategy, innovation, and competition in the effort to be more productive and more profitable. At the same time, the sector faces demands that it become more environmentally responsible in its policies and practices. This paper proposes a Lean Implementation Framework that small and mid-size farms can use as they aim to increase production and profit and yet support environmental sustainability. This case study takes an action-oriented research approach that focuses on the implementation of a Green Lean approach at 34 Swedish farms using various Lean tools. The paper describes how training sessions, farm visits, workshops, and counseling were used to introduce the farmers to the benefits and risks of the implementation of a new business model that added Green elements to the traditional business model design. The paper concludes with recommendations for adaptations to the Framework and suggestions for future research. © 2018

- The agri-food sector in Sweden, as in much of Europe, faces dramatic pressure to promote entrepreneurship, especially in rural areas where population aging and population decline pose grave economic threats to local communities. One solution is the government policy of supporting the entrepreneurial ambitions of newly arrived immigrants. The policy is seen as doubly beneficial: support for rural areas and support for immigrants not yet prepared to enter the regular workforce. Immigrant entrepreneurship seems to have the potential to lessen the harmful effects of current socio-economic challenges. This paper examines the immigrant entrepreneurship experience in the agri-food sector in Sweden. A qualitative research approach is used to evaluate interviews with 25 immigrant entrepreneurs on the various factors that motivated them to become self-employed entrepreneurs. The main factors are the lack of other employment opportunities, the desire for work autonomy and flexibility, and the chance for a better standard of living. The results show that personal characteristics and previous entrepreneurship experience are the best predictors of business success. The paper concludes with a call for a model for immigrant entrepreneurship and for more government reforms and policies aimed at supporting the immigrant entrepreneur.

- This paper investigates cultural diversity as means to business sustainability and competitive advantage for entrepreneurs in the agricultural sector. 80 agricultural entrepreneurs have been addressed in this study, which include face-to-face meetings between entrepreneurs and candidates for employment.While supportive of the idea of cultural diversity as a beneficial element of business sustainability, most farmers stated they lacked both the time and the resources to manage the issues associated with immigrant workers. However, lack of organisational changes and managerial skills can also be a potential barrier for integration when the farm address growth and employment ambitions.

Experimental Vitreous Substitution
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Blindness and visual disability are common following vitreoretinal pathologies such as open globe injury, proliferative diabetic retinopathy, and rhegmatogenous retinal detachment (RRD). These conditions often necessitate surgical intervention using vitrectomy with a tamponading vitreous substitute. However, current tamponades are all associated with complications such as inflammation, cataract, glaucoma, and optic nerve atrophy. Translation of new vitreous substitutes into clinical use has proven to be challenging, due to a lack of a comprehensive methodology and numerous requirements; bio-compatibility and clinical.In this thesis, we explore several novel vitreous substitutes using newly developed methods with the ultimate goal of clinical translation.First, in an in vitro adult rat retinal explant culture assay, polyethylene glycol, and Bio-Alcamid® gels provoked retinal degeneration, while a cross-linked hyaluronic acid hydrogel, Healaflow®, matched, and even surpassed the preservation of structure when compared with medium only. Secondly, Healaflow® used as a vitreous substitute in an in vivo rabbit vitrectomy model revealed practical usability and favorable bio- compatibility. In a third study, vitreous substitutes with disparate biocompatibility profiles (silicone oil, Healaflow®, Bio-Alcamid®, and BSS) elicited different patterns of intrinsic and extrinsic retinal inflammation in vivo. Finally, a new rabbit repeat vitrectomy RRD-model revealed excellent tamponading effect of the Healaflow® gel.The combination of the presented in vivo and in vitro methods comprise a new paradigm in translational development of novel vitreous substitutes. Healaflow® stands out as a promising candidate for future clinical use as a vitreous substitute.

- There is a growing trend of using digital production, such as additive manufacturing, in direct consumer markets. Digital production enables new and advanced tools, which provide shorter development time and lower cost for manufacturing. In this paper we focus on the education and learning environment for digital production and prototyping at a fabrication laboratory (FabLab). FabLab (Fabrication Laboratory) is a small-scale innovation space offering digital fabrication and production. A FabLab is, among many things, a platform for learning and exchanging experience when experimenting and developing new solutions. FabLabs bring together students, researchers and teachers as well as industrial partners in a single physical location for the purposes of designing, prototyping, and do-it-yourself manufacturing. This explorative and creative environment provide insights to knowledge creation, based on the constructive learning theory, which address active involvement by the participants. To take full advantage of this creative learning environment, aspects such as student characteristics, the nature of the subject matter, and the teaching carried out by the staff, also needs to be addressed. © 2019 International Institute of Informatics and Systemics

Immigrant Labour in Swedish Agriculture : A Sustainable Business Model Innovation
- 2018
-
Konferensbidrag (refereegranskat)abstract
- This paper investigates cultural diversity as means to business sustainability and competitive advantage for entrepreneurs in the agricultural sector. The paper focuses on challenges and barriers in immigrant workforce integration as revealed by a year-long project conducted among farmers in the region of Halland (on Sweden’s southwest coast). The paper reports on a matchmaking project between farmers seeking employees and job seekers (immigrants) seeking employment. The project began with interviews with 80 farmers and continued with an exploratory meeting with 42 farmers, four discussion meetings with 16 farmers, and face-to-face meetings between farmers and candidates for employment. The project concluded with follow-up interviews with the 42 farmers. While 42 of the 80 farmers were interested in exploring the benefits of immigrant workforce integration, the others (53%) declined further participation in the project. Ultimately, one farmer hired three immigrants. While supportive of the idea of cultural diversity as a beneficial element of business sustainability, most farmers stated they lacked both the time and the resources to manage the issues associated with immigrant workers such as their lack of technical and mechanical skills, and the language differences.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: To investigate the inflammatory response of current and future potential vitreous substitutes in an experimental in vivo vitrectomy model.METHODS: Twenty-five gauge pars plana vitrectomy was performed in the right eye of 60 pigmented rabbits, with subsequent injection of 0.5-1.0 ml of Healaflow® (cross-linked hyaluronic acid, n = 12), Bio-Alcamid® (polyalkylimide, n = 8), silicone oil (n = 12), or balanced saline solution (BSS, n = 28). Postoperative clinical evaluation was performed; and the rabbits were sacrificed at 1 day, 1 week, or 1 month. The eyecups were then examined macroscopically; the retinas sectioned and stained with hematoxylin and eosin (Htx), and immunohistochemically labeled for glial fibrillary acidic protein (GFAP), CD45, galectin-3, CD68, and CD20. Unoperated left eyes from treated animals as well as eyes from untreated animals were used as controls.RESULTS: Vitrectomy without major complications was achieved in 46/60 eyes. The remaining 14 eyes were analyzed separately. One eye developed endophthalmitis after 1 week and was excluded. Eyes treated with Healaflow®, silicone oil, and BSS had a comparable appearance macroscopically and in Htx-stained sections, whereas Bio-Alcamid®-injected eyes exhibited increased macroscopic inflammation and severely affected retinas. GFAP upregulation was present in all treatment groups, most prominent in eyes treated with Bio-Alcamid® and silicone oil. Upregulation of CD45 and CD68 in the inner retina and vitreous space was most prominent with Bio-Alcamid® treatment, and these eyes together with their silicone oil-treated counterparts also displayed a stronger upregulation of CD20-labeled cells compared with remaining groups. General upregulation of galectin-3, mainly in the inner retina, was found in all groups. In eyes with perioperative complications, labeling of CD45, CD68, and especially GFAP was comparably high.CONCLUSIONS: We here describe differences in the postsurgery inflammatory profiles of existing and potential vitreous substitutes. Bio-Alcamid® and silicone oil display severe signs of gliosis and inflammation, whereas Healaflow® elicits minimal reactions comparable with BSS, highlighting its potential application as a vitreous substitute in a future clinical setting.

Tidskriftsartikel (refereegranskat)abstract
- Food waste is an important topic in the context of sustainable development. Although many studies have addressed this topic, there is still limited knowledge owing to insufficient data. This study reports on food waste in two institutional settings in a Swedish municipality: schools and elderly care homes. The findings suggest it is easier to measure and reduce food waste in stable environments, such as exist at schools, than at environments characterized by change and unpredictability, such as exist at elderly care homes. Specific areas examined and compared include cooking and receiving kitchens, infrastructure, communications, and support. © North American Business Press.

The use and abuse of 3D-printing from a business model perspective
- 2016
-
Konferensbidrag (refereegranskat)abstract
- The paper analyses changes in user activities and behaviour across different types of actors following the introduction of 3D printers. 3D printing, or additive manufacturing, has been claimed to disrupt manufacturing, allowing firms to move from prototyping to full-scale end-part production and replacement part production in a one-step process. 3D printing has many different uses, for example, the manufacturing of toys, shoes, lamps and fashion accessories, and by implication many different types of users and buyers. There are few empirical studies on the types of uses and users of 3D, hampering our understanding in what ways the 3D printers may change the behaviour of users, and whether 3D printers affect the likelihood and the nature of entrepreneurship or business model innovation. To investigate this, a model was created based on the 3DP literature. The model is applied on a distributor customer database and four interview-based illustrative case studies. The empirical findings show that the use of 3DP a) lowers the knowledge and resource barriers for experimentation and entrepreneurial entry, b) increases product and concept prototyping in product development, c) provides a potential for business model innovation by expanding the boundaries of the firm upstream and downstream, and d) becomes a ticket for entrepreneurial entry. Based on our results, the paper suggests that the potential of 3D printers alter user innovative activities is high but most of the potential is latent.

Forskningsöversikt (refereegranskat)abstract
- This paper aims to increase our understanding of sustainable business model innovation in the agri-food sector in terms of its theoretical and practical approaches for sustainability and their degree of complexity and maturity. The paper is based on a systematic literature review of 570 journal articles on business models and business model innovation published between 1990 and 2014. Of these articles, only 21 have business model innovation as their main focus. The review shows that research interest in the agri-food sector has increased in these years. The paper proposes a conceptual framework for sustainable business model innovation in the agri-food sector that can be used to meet the challenges encountered in taking a sustainability perspective. © 2017 by the authors

Genome architecture enables local adaptation of Atlantic cod despite high connectivity
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Adaptation to local conditions is a fundamental process in evolution; however, mechanisms maintaining local adaptation despite high gene flow are still poorly understood. Marine ecosystems provide a wide array of diverse habitats that frequently promote ecological adaptation even in species characterized by strong levels of gene flow. As one example, populations of the marine fish Atlantic cod (Gadus morhua) are highly connected due to immense dispersal capabilities but nevertheless show local adaptation in several key traits. By combining population genomic analyses based on 12K single nucleotide polymorphisms with larval dispersal patterns inferred using a biophysical ocean model, we show that Atlantic cod individuals residing in sheltered estuarine habitats of Scandinavian fjords mainly belong to offshore oceanic populations with considerable connectivity between these diverse ecosystems. Nevertheless, we also find evidence for discrete fjord populations that are genetically differentiated from offshore populations, indicative of local adaptation, the degree of which appears to be influenced by connectivity. Analyses of the genomic architecture reveal a significant overrepresentation of a large ~5 Mb chromosomal rearrangement in fjord cod, previously proposed to comprise genes critical for the survival at low salinities. This suggests that despite considerable connectivity with offshore populations, local adaptation to fjord environments may be enabled by suppression of recombination in the rearranged region. Our study provides new insights into the potential of local adaptation in high gene flow species within fine geographical scales and highlights the importance of genome architecture in analyses of ecological adaptation.

Oxygen Adsorption on Graphene-Encapsulated Palladium Nanoparticles Imaged by Kelvin Probe Force Microscopy
- 2019
-
Ingår i: Journal of Physical Chemistry C. - : American Chemical Society (ACS). - 1932-7447 .- 1932-7455. ; 123:40, s. 24615-24625

Tidskriftsartikel (refereegranskat)abstract
- Graphene-encapsulated metal nanoparticles (G@NPs) offer a possibility to observe confined reactions in the nanocontainer formed by the NP's facets and graphene. However, direct experimental detection of adsorbed atomic and molecular species under the graphene cover is still challenging, and the mechanisms of intercalation and adsorption are not well understood. Here, we show that Kelvin probe force microscopy can largely contribute to the understanding of adsorption and desorption at the single NP level, which we exemplify by comparing oxygen adsorption experiments obtained at as-prepared PdNPs and G@PdNPs, both supported on highly oriented pyrolytic graphite and studied under ultrahigh vacuum (UHV) conditions. We show that oxygen adsorption at room temperature occurs at a much higher partial oxygen pressure on G@PdNPs compared to as-prepared PdNPs. Similarly, the removal of oxygen via a reaction with the residual gas of the UHV is slower on the G@PdNPs compared to as-prepared PdNPs. The differences can be explained by a limited facility for reactant and product molecules to enter and desorb from the nanocontainer via the defects of the graphene. Experimental observations are supported by assisting density functional theory calculations.

Revealing Carbon Phenomena at Palladium Nanoparticles by Analyzing the Work Function

Tidskriftsartikel (refereegranskat)abstract
- Carbon at metal nanoparticles (NPs) plays a fundamental role in heterogeneous catalysis. However, as experimental detection of small amounts of carbon is difficult, in particular when occupying subsurface sites, reaction mechanisms involving absorbed carbon are highly debated. Here, we show that the work function (WF) of metal NPs can be used as a measure of carbon adsorption and absorption, which we demonstrate by Kelvin probe force microscopy and density functional theory calculations for (111)-faceted palladium NPs (PdNPs) on graphite. Growth of PdNPs between 150 and 480 °C leads to carbon etching of the graphite steps and carbon absorption into the first subsurface layer below the NP's facets. This strongly reduces the WF of Pd(111) by up to -1 eV. During a 1 h long postannealing at 650 °C, more carbon is etched from the graphite steps, leading to a carbon precursor structure adsorbed on the NP's facets, as verified by scanning tunneling microscopy. The carbonaceous structures are replaced by graphene upon further annealing (1 to 2 h), followed by a decrease in the WF by ∼-1.4 eV. Similar phenomena are observed after short-time ethylene decomposition at PdNPs at 650 °C. Apart from subsurface carbon, we suggest that the large WF shifts observed experimentally could be attributed to structural defects on NP's facets.

Conditions Enabling Development in National Lean Programmes
- 2016
-
Ingår i: Leadership & Organization Development Journal. - 0143-7739 .- 1472-5347.
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose – The purpose of this article is to identify work practices and activities at programme and local levels which constitute conditions that enable development in workplace development programmes (WPDPs). These are introduced by public agencies as change agents that provide the resources for local organizational change. Design/methodology/approach – The study constituted separate interactive research projects in three WPDPs conducted through a total of 256 interviews and documentation from meetings. The findings were compared in a qualitative content analysis. Findings – The outcomes of development processes in the programmes and local Lean implementation are enabled by the interplay of three conditions: a) organized learning activities with the stakeholders involved, b) key stakeholders’ active ownership and c) support for employee participation. The three conditions thus support programme management in leading the programme development processes. Research limitations/implications - The findings operationalize broad theoretical concepts. However, the research projects involved were not originally designed for this comparative study, which created some difficulties when performing the analysis. The longitudinal design and vast amount of data partly compensate for this. Practical implications – This knowledge will be helpful in the formation of new WPDPs that support local organizational development and for those who lead such processes. Originality/value – The novelty of the findings is the operationalization of broad theoretical concepts, such as the conditions that support development programmes. Moreover, this article shows a set of work practices and activities that management may be used in organizing WPDPs.

- The purpose of this article is to present and test a framework for lean implementation in the agricultural sector, addressing challenges from an operational and strategical perspective. The article builds on the previous literature on the use of Lean and reports empirical data from a lean implementation project in the south-western Sweden, including interviews, observations, diaries and questionnaires. A framework is developed to examine strategic and operational perspectives on Lean Thinking. Using this framework, a number of challenges encountered in Lean implementation are presented. This article is limited to the study of Lean among a group of Swedish farms although its findings may have implications for the wider agricultural sectors. Many societal challenges are linked with agricultural sustainability, stressing the need for productive, resource-efficient, resilient and less wasteful food production. This article is the first to develop and test a Lean implementation framework in the agriculture sector. © 2018 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.

Barriers and challenges in agriculture business development : A study of two leadership programs in Sweden
- 2017
-
Konferensbidrag (refereegranskat)abstract
- Purpose: The purpose of this empirical paper is to illustrate two leadership development programs in Swedish agriculture. Further, it is to compare the two programs related to outcomes in terms of barriers and challenges in the development process and suggest possible ways to continue the leadership development for business model innovation in the agricultural sector.Design/methodology/approach: The data collection includes 54 interviews and a survey sent to 109 entrepreneursin Sweden. The interviews were collected with (i) entrepreneurs who participated in the Project ‘Ledarpraktikan’ (‘Leader practice’) (LP) 2013 and (ii) entrepreneurs who participated in the project ‘Lean Agriculture’ (LA) 2012. The survey was sent in the spring 2017 to 109 entrepreneurs (37 from ´LP´, 35 from ´LA´ and 37 not having participated in any of the programs called control group ´CG´). The overall response rate in the survey is 68% (51% from ´LP´, 80% from ´LA´ and 73% from ‘CG’. Content analysis and descriptive analysis have been used in the study.Findings: From the qualitative studies, we can see that entrepreneurs having participated in ‘LP’ perceive that they have acquired deeper knowledge and understanding regarding selfleadership than entrepreneurs participating in ´LA´. The latter entrepreneurs also have described their need for more knowledge in self-leadership. The entrepreneurs participating in ´LA´ have, through analysis of the day-to-day work, acquired a more developed systematic working environment. The comparison between the three groups in the survey show that there are several similarities between the groups, for example they don´t see institutional rules to be barriers in their firm development process. We have found differences in barriers for business development in terms of (i) growth willingness, (ii) lack of employees, (iii) lack of support and (iv) lack of spare time.Practical implications: There is a need for further leadership development knowledge in Swedish agriculture, both for entrepreneurs in the development of their business models and for agricultural advisors regarding their new role as coaches instead of traditional advisers.Policy implications: It is important that organizations supporting financial solutions for the agricultural businesses also support leadership development programmes in the industry.Originality/value: The originality with the paper is that there has been two large analyses regarding two leadership development programs in Swedish agriculture, which is unique in this industry.

Local cod (Gadus morhua) revealed by egg surveys and population genetic analysis after longstanding depletion on the Swedish Skagerrak coast
- 2019
-
Ingår i: ICES Journal of Marine Science. - : Oxford University Press (OUP). - 1054-3139 .- 1095-9289. ; 76:2, s. 418-429
-
Tidskriftsartikel (refereegranskat)abstract
- Dramatic and persistent reductions in Atlantic cod (Gadus morhua) are common in many coastal areas. While offshore cod stocks still were abundant and productive, the Swedish west coast showed signs of diminishing adult cod abundance at the beginning of the 1980s, where the local cod component was considered to be extirpated. To survey the present cod spawning activity and stock composition, we initiated egg trawling over two consecutive years (203 hauls in total) in combination with population genetic analyses (425 individually genotyped eggs). Here, we provide evidence of cod spawning at the Swedish Skagerrak coast, suggesting recolonization or that local cod has recovered from a nearly depleted state. Early stage eggs were found inside fjords too far to have been transported by oceanic drift from offshore spawning areas. The cod eggs were genetically similar in early to late life-stages and cluster mainly with the local adult cod, indicating that eggs and adults belong to the same genetic unit. The cod eggs were genetically differentiated from adult North Sea cod, and, to a lesser degree, also from the Kattegat and Öresund cod, i.e. indicating a possible recovery of local coastal stock.The patterns of the genetic structure in the inshore areas are, however, difficult to fully disentangle, as Atlantic cod in the North Sea-Skagerrak area seem to be a mixture of co-existing forms: local cod completing their entire life cycle in fjords and sheltered areas, and oceanic populations showing homing behaviours. The egg abundances are considerably lower compared with what is found in similar studies along the Norwegian Skagerrak coast. Nevertheless, the discovery of locally spawning cod along the Swedish west coast—although at low biomasses—is an encouraging finding that highlights the needs for endurance in protective measures and of detailed surveys to secure intraspecific biodiversity and ecosystem services.

Tidskriftsartikel (refereegranskat)abstract
- PurposeBecause the business model is a fairly new concept, research is lacking on business model innovation in certain industry sectors. One such sector is the agri-food sector. Using a systematic literature review of peer-reviewed journal articles published from 1990 to 2014, this paper examines the where, when, and how of the use of business models and business model innovation in the agri-food sector.Design/methodology/approachA web-based search was conducted to identify peer-reviewed journal articles that contained a combination of “business model” or “business model innovation” with agriculture-related and food-related terms (e.g., “agri-food sector”). After winnowing out irrelevant and duplicate articles, 505 articles were chosen for analysis.FindingsUsing categories, the paper analyses various data about the selected articles. The categories include research settings, units of analysis, methodologies, and theories. Based on this analysis, the paper finds that these agri-food sector articles are primarily qualitative, empirical studies that focus on one or a few companies (i.e., case studies). The paper also finds that theory is not yet well developed in the research on the agri-food sector.Originality/valueSystematic literature reviews of various concepts, theories, and models are common in many fields (e.g., information/software technology, healthcare, and organizational management). However, no such review is available for the agri-food sector, in particular in its use of business models and business model innovation. This paper addresses that gap with its review of relevant articles published in more than 300 journals in recent years. Based on this review, the paper draws conclusions about business model innovation in the agri-food sector and offers suggestions for future research. © Emerald Group Publishing Limited

- The purpose of this article is to deepen our understanding of what we know about business model innovation in the agri-food sector, both from a theoretical as well as a practical perspective. The methodological approach used in the paper is built on interviews, focus groups and observations of agricultural entrepreneurs and agricultural advisors in the agriculture sector and a review of over 500 peer-reviewed research papers for the period 1990-2014. The findings of the study indicate that entrepreneurs within the agri-food sector ought to shift focus from only a producer perspective to also include an entrepreneurial perspective, e.g. to focus on business model innovation. Based on this knowledge the authors present implications for research and practice. The research field is young and broad, but developing, and in need of stronger theoretical foundations. This article is based on a combination of a systematic literature review of a new emerging field as well as empirical in-depth interviews, focus groups and observations. © 2016, IGI Global.

Tidskriftsartikel (refereegranskat)abstract
- The importance of business model innovation (BMI) is widely recognized. BMI is especially important in the agri-food industry that faces enormous challenges as the demand for food increases worldwide. Much of the BMI research focuses on the technology and biomedical industries. Far less attention has been paid to the agri-food industry. This article is a systematic literature review of the BMI research in the agri-food industry. The article’s aim is to identify and categorize various barriers to BMI as described in the literature (in English) published in peer-reviewed journals between 1990 and 2014. The findings show a fairly even distribution among external and internal BMI barriers. Because the main barrier is the mind-set that is resistant to change, it is recommended the researchers and practitioners should focus more on the cognitive barriers to BMI in the agri-food industry.
