Abstract
Purpose
The purpose of this paper is to identify which plant protection practices consumers prefer and why. The authors focused on beneficial insects, genetically modified (GM) plants, synthetic chemical pesticides, biological plant protection, mechanical-physical plant protection as well as biotechnical plant protection. The authors studied the effects of the risk perception and both subjective and objective knowledge on preference.
Design/methodology/approach
The authors collected cross-sectional data from n = 1,223 people living in Germany. For this, the authors used an online panel and quoted participation after age, gender, income and region. The authors used multiple regression analyses and also explored moderation effects of knowledge on risk perception to explain participants' preferences.
Findings
The most preferred plant protection practice in the study sample was the application of beneficial insects. The authors found evidence that risk perception, as well as objective and subjective knowledge, can have a pivotal direct effect on preferences. Additionally, subjective as well as objective knowledge typically moderated the effect of risk perception, depending on the plant protection practice in focus. Overall, the authors found that levels of subjective and objective knowledge of plant protection practices were rather low among German participants.
Originality/value
While studies on consumer preferences for GM or organic food are abundant, preferences regarding other types of common plant protection practices are hardly investigated. To tackle this research gap, the authors focused on six different and common plant protection practices and compare results.

Abstract
Purpose
This research aims to propose a model for the complex decision-making involved in the ecological restoration of mega-infrastructure (e.g. railway engineering). This model is based on multi-source heterogeneous data and will enable stakeholders to solve practical problems in decision-making processes and prevent delayed responses to the demand for ecological restoration.
Design/methodology/approach
Based on the principle of complexity degradation, this research collects and brings together multi-source heterogeneous data, including meteorological station data, remote sensing image data, railway engineering ecological risk text data and ecological restoration text data. Further, this research establishes an ecological restoration plan library to form input feature vectors. Random forest is used for classification decisions. The ecological restoration technologies and restoration plant species suitable for different regions are generated.
Findings
This research can effectively assist managers of mega-infrastructure projects in making ecological restoration decisions. The accuracy of the model reaches 0.83. Based on the natural environment and construction disturbances in different regions, this model can determine suitable types of trees, shrubs and herbs for planting, as well as the corresponding ecological restoration technologies needed.
Practical implications
Managers should pay attention to the multiple types of data generated in different stages of megaproject and identify the internal relationships between these multi-source heterogeneous data, which provides a decision-making basis for complex management decisions. The coupling between ecological restoration technologies and restoration plant species is also an important factor in improving the efficiency of ecological compensation.
Originality/value
Unlike previous studies, which have selected a typical section of a railway for specialized analysis, the complex decision-making model for ecological restoration proposed in this research has wider geographical applicability and can better meet the diverse ecological restoration needs of railway projects that span large regions.

The purpose of this paper is to investigate the impact of biotechnological inventions and innovations on the organization of the burgeoning Atlantic salmon farming industry.
Abstract
Purpose
The purpose of this paper is to investigate the impact of biotechnological inventions and innovations on the organization of the burgeoning Atlantic salmon farming industry.
Design/methodology/approach
The authors study how novel biotechnological inventions are utilized within Atlantic salmon aquaculture. The authors compare the findings with the historical development path of invention and innovation in the plant sector, and explore parallels and dissimilarities between the plant breeding sector and Atlantic salmon aquaculture.
Findings
The innovation capacity within Atlantic salmon aquaculture is distinct from the plant sector, but nonetheless likely to become equifinal. Similar to plants, the female fecundity of salmon is high. Hybridization, which is an effective mechanism for protection of investments in high fecundity organisms, is less effective in salmon farming because the genetic variability is higher in salmon. Hybridization provides plant breeders with significant power over grow-out farmers. The development path in Atlantic salmon sector is distinctively dissimilar from plants, but salmon farmers nonetheless appear to move toward the structural configurations that are parallel to the plant sector. The significance of new breeding technologies in Atlantic salmon farming ascends, and will play an increasingly important role in the further development of this industry.
Research limitations/implications
The study contributes to the prevailing knowledge of how inventions and innovations influence the future development of the Atlantic salmon industry.
Originality/value
Biotechnological inventions are evolving within aquaculture. So far, the implications of novel biotechnological possibilities for the Atlantic salmon sector have been underanalyzed. The paper explores these implications from the perspective of political economy.

Abstract
Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
The issue of the genetic manipulation of plants, animals and microbes is addressed within the context of food production. Genetic manipulation is defined within the wider area of biotechnology and some of the main benefits of its use are summarised; safety and risk are examined and some of the socioeconomic problems it can create are discussed. It is concluded that the technique can offer great potential benefits in terms of increased quantity and improved quality of food, but it raises social/ethical concerns which can be summed up by asking: Is it safe? Is it fair? Is it natural?

Abstract
Purpose
The purpose of this paper covers a perspective as related to sustainable development of natural resources with a focus on application of biotechnology in waste management.
Design/methodology/approach
The paper presents an overall view of industrial waste management practices as pertaining to substantiality of resources with emphasis on biodegradation of industrial pollutants. Methodologies employing biotechnology and striving towards the goal of sustainable development/production are discussed in this regard and particular attention is given to: regulatory consideration and trends; characterization of toxics for resource reuse; ecotoxicological assessment evaluations; treatment trends and innovative techniques, residual management.
Findings
Biotechnology is an important component needed to successfully achieve the goal of sustainability. “Value‐added” products from by‐products/waste and novel technologies employing biotechnical principles represent areas where significant opportunities exist.
Practical implications
The approach described here not only applies to water resource management but also includes multi‐media and multi‐disciplinary consideration.
Originality/value
The information presented herein hopefully will stimulate discussion and act as a catalyst for future direction. It perhaps may also serve as a point of reference for future evaluations of accomplishment.

Abstract
Purpose
The purpose of this paper is to investigate consumer preferences in the Slovenian context with regard to cheese, ham and honey labelled with the national and EU protected designation of origin (PDO) indication and the protected geographical indication (PGI) associated with price and origin.
Design/methodology/approach
An online survey with a representative sample of the Slovenian population of 650 consumers was conducted. Consumer preferences were estimated using choice-based conjoint analysis.
Findings
The findings show that price is the most powerful driver of consumer preferences for cheese and honey, whereas it is origin for ham, which proved to be the most strongly desired “Slovenian” food product of all items analysed. Label is the least preferable attribute for all three products considered. Cheese, ham and honey bearing the national PDO and PGI labels were more desired than products carrying the EU PDO and PGI labels. The study findings also show the main statistically significant differences in the age and gender of consumers.
Research limitations/implications
The biggest limitation is that the study focused on certain labels only, related to quality, and origin in particular.
Practical implications
This result highlights the need to extend and intensify promotional and communication activities to increase consumer preferences for the national and EU PDO- and PGI-labelled cheeses, ham and honey.
Originality/value
This study contributes to relevant literature by presenting the results regarding consumer preferences for the EU and national quality labels for different food categories in Slovenia, which has no tradition in using the EU quality labels.

Abstract
The Report of the Committee on the Ethics of Genetic Modification and Food Use was published in September 1993. The use of genetic engineering for food use has received a lot of media and welfare group attention. Addresses emerging ethical issues which affect many societal groups. Information, education and labelling are key factors in the public′s understanding and acceptance of foods produced by this technology. The recommendations of the report have resulted in the Food Advisory Committee (FAC) proposals for labelling products of gene technology. These will not go far enough to satisfy all those who made submissions to the Committee on Ethics. There is a gap between the public′s perception of science and the evidence presented by the biotechnology researchers. The effectiveness of any decisions on labelling hinges not only on more detailed labelling but on bridging the gap between the conflicting interests of scientists and societal welfare groups, so that consumers can make informed choices based on facts.
