Abstract: White horehound (Marrubium vulgare L.), is a troublesome weed of arid zones, particularly in cropping and grazing areas. Understanding the seed ecology of white horehound is relevant to its management. The present study investigated the effects of temperature, light, osmotic potential, salinity, pH, and seeding depth on seed germination and seedling emergence of white horehound. Seeds germinated over a wide range of temperatures, with highest germination (100%) occurring at 25/20°C in either 12-h alternating light/dark or complete darkness. Germination decreased from 92% to 10% as the osmotic potential decreased from 0 to minus 0.6 MPa and germination was completely inhibited at minus 0.8 MPa. Increasing concentration of sodium chloride (salinity) from 50 to 150 mM reduced germination from 68% to 11% but was completely inhibited at 200 mM. Germination was not limited by variation of pH in solutions of pH 5 to pH 10. Maximum germination (99%) occurred at pH 7, but slightly decreased (90%) in acidic or alkaline media. Surface located seeds were highly germinable (87%) where seedling emergence significantly declined as seeding depth increased from 0.5 to 3 cm. Nil seedling emergence was occurred at 4 cm burial depth. Light significantly affected germination, time to 50% germination, mean germination time and germination index. Increasing osmotic and salinity stress both significantly increased the time to start germination, time to 50% germination, mean germination time, but decreased germination index. Burial depth adversely affected seedling emergence with surface located seedlings emerging earlier (4.2 days) compared with 20 days for seeds buried at 3 cm. Results suggest that effective management of white horehound should consider targeting surface located seeds in combination with tools that induce minimal soil disturbance, particularly in relatively non-saline environments.

Abstract: To examine the literature on corporate entrepreneurship and innovation and to develop a combined definition of these two terms. Moreover, the literature is used to construct a holistic model that seeks to explain the links between corporate entrepreneurial activity and the innovation process. A number of published works on entrepreneurship and innovation are critiqued. The findings from this literature review are used to develop a framework illustrating the relationships between the corporate entrepreneur and the innovation process. The paper presents a combined definition of corporate entrepreneurship and innovation and, from the literature review, concludes that previous models on entrepreneurship and innovation are fragmented because there is little exploration on the relationships and dynamics between these two factors. A framework of corporate entrepreneurship and innovation is constructed by synthesising the information gathered from previous literature. This model shows that there are missing links between the entrepreneur and the innovation process. The paper discusses three factors that may explain both the dynamics and the relationships between the entrepreneur and the innovation process. These are entrepreneurial attitudes, vision and actions. This paper fulfils an identified gap in the literature, namely the lack of investigation into the links between the corporate entrepreneur and the innovation process, and suggests three factors that could be used to explain this gap. Part 2 of this paper will present a new holistic model of corporate entrepreneurship and innovation that illustrates the relationships between these two areas in more detail.

Abstract: – The purpose of this paper is to address an important question which centres on investigating how do manufacturing businesses perceive and understand the concepts of agility and flexibility in their supply chains (SCs). – A case study approach was utilised and data were gathered from semi-structured interviews with ten organisations in the Australian manufacturing sector. Data analysis was conducted using analytic techniques based on, for ex le, pattern matching and cross-case synthesis. – Findings confirmed that there is some ambiguity concerning the understanding of the terms agile and flexible, both within and between organisations. The implications are that there is often little consistency in the way the terms are operationalised and then applied. In this regard, and to inform future research, the paper offers empirically grounded definitions for SC agility and flexibility. Moreover, four propositions are developed and discussed which shed light on the dynamics of agility and flexibility in the SC. – This is one of the first empirical studies to address some of the apparent inconsistencies between organisational applications of agility and flexibility, and their impact on SC operations.

Abstract: The paper aims to explain how agency theory can be used to inform our understanding of the dynamics surrounding supply chain behaviours and relationships. A structured review of the literature using a three‐stage refinement process is used. The articles were sourced through online databases and keyword classifications, such as “agency theory”, “principal‐agent relationships” and “supply chain management”. The search initially identified over 86 articles. After further screening these were reduced to 19 for final assessment and comparison. Despite agency theory's prevailing descriptive and predictive qualities there is scarcity in its application to the SCM discipline. The authors posit that agency theory provides valuable insights for relationship engineering within supply chains where social, political, legal and behavioural dynamics dominate. It is a critical task for managers to understand and mitigate abnormal behaviours across the supply chain. Agency theory serves this need by providing them with a useful tool to respond to transaction cost dilemmas through contractual and non‐contractual remedies. This is one of the first studies that examines the current state of agency theory application in the SCM literature and suggests potential avenues for future research.

Abstract: To extend the discussion held in part 1, and develop a two‐tier fifth‐generation model of corporate entrepreneurship and innovation. The components that have been synthesized from a review of the literature in Part 1 are extended using evidence from the literature. These components are used to construct a two‐tier model of corporate entrepreneurship and innovation a macro model which presents the high‐level environmental drivers of innovation and a micro model that discusses the contextual factors that underpin the corporate entrepreneurship and innovation process. From the analysis conducted in part 1 it is evident that there is a strong relationship between the role of the corporate entrepreneur and the innovation process. It is suggested that by separating the corporate entrepreneur from the innovation process previous models have been overly reductionist in their construction, and their utility has, as a consequence, been severely constrained. The study therefore combines the role and activities of the entrepreneur with the innovation process into a unified framework. In doing so the paper develops a two‐tier fifth‐generation model of corporate entrepreneurship and innovation. The final sections of the paper present the model's implications for management and suggestions for further research. This paper fulfils an identified gap in the literature, namely the development of a new holistic model of corporate entrepreneurship and innovation, which illustrates the environmental and contextual relationships between the corporate entrepreneur and the innovation process.

Abstract: The purpose of this paper is to investigate the impact of behaviour-based and buffer-based management mechanisms on enterprise agility using the lens of the agency theory. This study is based on data collected from 185 manufacturing enterprises using a survey instrument. The authors employ structural equation modelling for data analysis. The results of this study show that buffer-based mechanisms used for dealing with agency uncertainty of supplier/buyer not only have a positive impact on agility of enterprises, but are also contingent on the behavioural interventions used in the relationship with a supplier/buyer. Behaviour-based mechanisms also positively impact enterprise agility through mitigating the likelihood of supplier/buyer opportunism. This study demonstrates that buffer- and behaviour-based management mechanisms can be used as complementary approaches against agency uncertainties for enhancing enterprise agility. Therefore, for enterprises to boost their agility, it is vital that their resources and capabilities are fairly distributed across entities responsible for creating buffers through functional flexibility, as well as in iduals and teams dealing with stakeholder engagement, in particular, suppliers and buyers. The authors use the lens of the agency theory to assimilate and model characteristic agency uncertainties and management mechanisms that enhance enterprise agility.

Abstract: Bhutan is a small country in the Himalayan mountains where subsistence agriculture is practiced due to small land holdings and undulating mountainous terrains. Due to erse altitudinal and agro-ecological environments, many food crops are cultivated. Wheat is currently a secondary cereal, grown over an area of 1,964 ha with a total production of 3,465 Mg. While there are enormous opportunities to increase wheat production in Bhutan, it is challenged by numerous biotic and socio-economic factors such as labour shortage and low economic return. Among the biotic constraints, stripe rust and leaf rust are the most important diseases. Stem rust has not yet been reported. Poor crop nutrition, both through low soil fertility and inadequate external supply, also results in low productivity. In addition, better remunerative crops and affordable-imported products discourage wheat production. However, the availability and accessibility to higher yielding disease-resistant varieties, fertilization (both organic and inorganic), appropriate seed rate, optimum planting time, mechanization, rotation with legumes and expansion of wheat area are some measures that will play a crucial role in managing sustainable wheat production in Bhutan. In this paper, we provide a brief overview of the current scenario of wheat production, discuss the constraints and provide strategic guidance to improve wheat production in Bhutan.

Abstract: – The purpose of this paper is to discuss how decisions regarding organisational flexibility can be improved through targeted resource allocation, by focusing on the supply chain's level of uncertainty exposure. Specifically, the issue of where and in what ways flexibility has been incorporated across the organisation's supply chain is addressed. – A two-phase methodology design based on literature review and case study was used. Using 83 journal articles in the areas of uncertainty and flexibility an analytical process for assessing uncertainty-flexibility mismatches was developed. Furthermore, results from ten interviews with senior/middle managers within the Australian manufacturing sector were used to provide preliminary insights on the usefulness and importance of the analytical process and its relationship with organisational practice. – The paper emphasises the importance of having a systematic and encompassing view of uncertainty-flexibility mismatches across the supply chain, as well as the significance of socio-technical engagement. The paper both conceptually and empirically illustrates how, using a structured analytical process, flexibility requirements across the supply, process, control and demand segments of a supply chain might be assessed. A four-step analytical process was accordingly developed and, its application, usefulness and importance discussed using empirical data. – The analytical process presented in this paper can assist managers to obtain a comprehensive overview of supply chain flexibility when dealing with situations involving uncertainty. This can facilitate and improve their decision-making with respect to prioritising attention on identified flexibility gaps in order to ensure stability of their performance. – The paper presents a supply chain-wide discussion on the difficulties that uncertainty brings to organisations, and how organisational flexibility might serve to moderate those challenges for supply chain management. It discusses how to identify the flexibility gap and proposes an original analytical process for systematic assessment of uncertainty-flexibility mismatches.
