Habitual Entrepreneurs

Previous studies on habitual entrepreneurs have not researched in any depth the processes and strategies associated with the growth of business clusters by habitual entrepreneurs. To gain insights into these issues, case studies were conducted with habitual entrepreneurs who owned high-growth businesses in Scotland. The research involved the analysis of life histories and business genealogies. A diversity was found in the backgrounds of the entrepreneurs studied, in the types of ventures founded, and in strategies adopted to build up their cluster of companies. Entrepreneurial motives, strategies, and practices by habitual entrepreneurs in building their business ownership clusters not only can differ markedly from one entrepreneur or type of entrepreneur to another, but also by individual entrepreneurs over time. Despite this diversity, little evidence emerged that the growth of business ownership clusters was motivated by orthodox corporate management principles, though corporate management practices were employed in some cases to subsequently assimilate the new venture into a cluster. On balance, entrepreneurial opportunism was more prevalent than planned “survivalist” diversification. Further, the concept of “entrepreneurial” performance is introduced to distinguish performance through creating a cluster of ventures rather than through growing a single one.

As digitization becomes pervasive, many organizations struggle to drive value from the growing number of IT-related opportunities. We show how the drivers of IT value creation can be framed as firm-wide commitments to a set of IT capabilities. On the basis of 20 published case studies, we identify a small set of IT decisions that organizations must make to use IT to successfully enhance their impact. We group these decisions into a framework of four commitments. Making these commitments helps organizations reinforce what really matters over time, which in turn helps focus the attention of their employees. We demonstrate, via a survey of 210 publicly traded firms, that firms which are more effective in making these four commitments have higher business impact from IT, which in turn correlates with higher financial performance. We suggest the construct of commitment is a step toward unifying the IT value literature and creating an overarching concept that brings together many of the important management practices identified in previous work.

There is an increasing body of work in the area of hardware defenses for software-driven security attacks. A significant challenge in developing these defenses is that the space of security vulnerabilities and exploits is large and not fully understood. This results in specific point defenses that aim to patch particular vulnerabilities. While these defenses are valuable, they are often blindsided by fresh attacks that exploit new vulnerabilities. This article aims to address this issue by suggesting ways to make future defenses more durable based on an organization of security vulnerabilities as they arise throughout the program life cycle. We classify these vulnerability sources through programming, compilation, and hardware realization, and we show how each source introduces unintended states and transitions into the implementation. Further, we show how security exploits gain control by moving the implementation to an unintended state using knowledge of these sources and how defenses work to prevent these transitions. This framework of analyzing vulnerability sources, exploits, and defenses provides insights into developing durable defenses that could defend against broader categories of exploits. We present illustrative case studies of four important attack genealogies—showing how they fit into the presented framework and how the sophistication of the exploits and defenses have evolved over time, providing us insights for the future.

Over Time

Pipelines can be exposed at water crossings where rivers lower the channel bed. Channel bed scour may cause damage to linear infrastructure such as pipelines by exposing the pipe to the flow of water and sediment. Accurate estimation of depth of scour is therefore critical in limiting damage to infrastructure. Channel bed scour has three main components: (1) general scour, (2) bed degradation, and (3) pool depth. General scour is the temporary lowering of the channel bed during a flood event. Channel bed degradation is the systematic lowering of a channel bed over time. Pool depth is depth of pools below the general bed elevation and includes the relocation of pools that result from river dynamics. Channel degradation is assessed in the field using indicators of channel incision such as channel bed armoring and bank characteristics, through the analysis of long profiles and sediment transport modelling. Pool depth is assessed using long profiles and channel movement over time. The catastrophic nature of bed lowering due to general scour requires a different assessment. A design depth of cover is based on analysis of depth of scour for a given return period (eg. 100-years). There are three main steps to predict general scour: (1) regional flood frequency analysis, (2) estimation of hydraulic variables, and (3) scour depth modelling. Typically, four scour models are employed: Lacey (1930), Blench (1969), Neill (1973), and Zeller (1981), with the average or maximum value used for design depth. We provide herein case studies for potential scour for pipeline water crossings at the Little Smoky River and Joachim Creek, AB. Using the four models above, and an analysis of channel degradation and pool depth, the recommended minimum depth of cover of 0.75 m and 0.142 m, respectively, were prescribed. Variability between scour models is large. The general scour model results varied from 0.45 m and 0.75 m for the Little Smoky River and 0.16 m to 0.51 m for Joachim Creek. While these models are more than 30 years old and do not adequately account for factors such as sediment mobility, they nevertheless do provide usable answers and should form part of the usual toolbox in water crossing scour calculations.

Climate change is expected to have significant impacts on hydrologic regimes and freshwater ecosystems, and yet few basins have adequate numerical models to guide the development of freshwater climate adaptation strategies. Such strategies can build on existing freshwater conservation activities, and incorporate predicted climate change impacts. We illustrate this concept with three case studies. In the Upper Klamath Basin of the western USA, a shift in land management practices would buffer this landscape from a declining snowpack. In the Murray–Darling Basin of south-eastern Australia, identifying the requirements of flood-dependent natural values would better inform the delivery of environmental water in response to reduced runoff and less water. In the Savannah Basin of the south-eastern USA, dam managers are considering technological and engineering upgrades in response to more severe floods and droughts, which would also improve the implementation of recommended environmental flows. Even though the three case studies are in different landscapes, they all contain significant freshwater biodiversity values. These values are threatened by water allocation problems that will be exacerbated by climate change, and yet all provide opportunities for the development of effective climate adaptation strategies.

Purpose – The purpose of this paper was to examine changes in the contents of Canadian corporate codes of ethics over a period of two decades from an institutionalization perspective. Design/methodology/approach – The paper tracks changes in the contents of the codes of large Canadian corporations longitudinally by analyzing their contents at two points over two decades, in 1992 and 2012. In particular, the paper tests three hypotheses related to the institutionalization of codes. Findings – It was found that the codes have become more prescriptive, they are more concerned with social responsibility and are more likely to identify their moral and legal authority. Overall, the findings support an institutional interpretation of the observed changes. Research limitations/implications – While large corporations are critical in establishing new and innovative management practices, their selection as the study population limits the generalizabilty of the findings. Another limitation of this paper is that it used an a priori determined set of items to analyze the contents of the codes and while this was needed to facilitate the comparison across time, it also meant that some important items were not clearly identified. Originality/value – Codes of ethics are the foundation of ethics programs in corporations and their contents could be critical in the development of a culture of ethics in corporations. This paper makes a valuable contribution to research on business ethics by analyzing the codes of ethics of the largest corporations in Canada at two points over two decades. The need to track changes in corporate codes of ethics over time has been advocated by several researchers, but longitudinal studies in this area are rare.

Several regulatory agencies and universities have published guidelines addressing the use of wood ash as liming material for agricultural land and as a soil amendment and fertilizer. This paper summarizes the experiences collected from several forest products facility-sponsored agricultural application programs across North America. These case studies are characterized in terms of the quality of the wood ash involved in the agricultural application, approval requirements, recommended management practices, agricultural benefits of wood ash, and challenges confronted by ash generators and farmers during storage, handling, and land application of wood ash. Reported benefits associated with land-applying wood ash include increasing the pH of acidic soils, improving soil quality, and increasing crop yields. Farmers apply wood ash on their land because in addition to its liming value, it has been shown to effectively fertilize the soil while maintaining soil pH at a level that is optimal for plant growth. Given the content of calcium, potassium, and magnesium that wood ash supplies to the soil, wood ash also improves soil tilth. Wood ash has also proven to be a cost-effective alternative to agricultural lime, especially in rural areas where access to commercial agricultural lime is limited. Some of the challenges identified in the review of case studies include lengthy application approvals in some jurisdictions; weather-related issues associated with delivery, storage, and application of wood ash; maintaining consistent ash quality; inaccurate assessment of required ash testing; potential increased equipment maintenance; and misconceptions on the part of some farmers and government agencies regarding the effect and efficacy of wood ash on soil quality and crop productivity.

Global logistics companies are increasingly disclosing carbon related information due to institutional and stakeholder pressures. Existing research, however, is limited to categorizing these pressures and their influences on corporate carbon disclosure strategies. In particular, literature to date has not distinguished between different carbon disclosure strategies and how they may have changed over time. In response, this paper: (1) proposes a framework that depicts four different carbon disclosure responses and strategies based on internal and external pressures; and (2) subsequently analyzes and compares corporate carbon disclosure strategies between 2010 and 2015. Using a sample of 39 leading global logistics companies, carbon disclosure strategies are categorized based on the analysis of 25 applied carbon management practices from Bloomberg ESG to see if carbon management practices and the associated strategies have changed. The findings show overall shifts to more transparent corporate carbon disclosure strategies between 2010 and 2015 with an increase of applied carbon management practices in both internal and external actions.

Soil texture varies significantly within many agricultural fields. The physical properties of soil, such as soil texture, have a direct effect on water holding capacity, cation exchange capacity, crop yield, production capability, and nitrogen (N) loss variations within a field. In short, mobile nutrients are used, lost, and stored differently as soil textures vary. A uniform application of N to varying soils results in a wide range of N availability to the crop. N applied in excess of crop usage results in a waste of the grower’s input expense, a potential negative effect on the environment, and in some crops a reduction of crop quality, yield, and harvestability. Inadequate N levels represent a lost opportunity for crop yield and profit. The global positioning system (GPS)-referenced mapping of bulk soil electrical conductivity (EC) has been shown to serve as an effective proxy for soil texture and other soil properties. Soils with a high clay content conduct more electricity than coarser textured soils, which results in higher EC values. This paper will describe the EC mapping process and provide case studies of site-specific N applications based on EC maps. Results of these case studies suggest that N can be managed site-specifically using a variety of management practices, including soil sampling, variable yield goals, and cropping history.

Purpose – Business research and entrepreneurship literature typically examines external resources as input or output of entrepreneurial (or high) growth. The purpose of this paper is to combine these two perspectives in describing and modeling high growth. Design/methodology/approach – The study tests the hypotheses on a sample of medium-sized, established manufacturing firms using structural equation modeling. Findings – Results provide original contributions to the business research on firm growth and entrepreneurship. They are consistent with studies advocating the importance of adopting a process perspective when studying business growth to probe the causal mechanisms behind growth. Research limitations/implications – Being quantitative, this study does not address the dynamic interdependencies between proprietary and hybrid growth. However, the literature on entrepreneurship would benefit from qualitative studies that explore how successful and sustainable growth processes combine the two modes of growth. Originality/value – Findings partially discard the input and output approach in favor of a vision of entrepreneurial growth as a process that unfolds over time with the development of external relationships. Only the process of collaboration, a core competence of entrepreneurial firms, reduces information asymmetries and agency problems, thus turning the corresponding inter-organizational relationships into formidable feeders of firm growth. Entrepreneurial growth is in fact a process that needs external relationships in order to flourish over time.

The Mississippi River Valley Alluvial Aquifer (MRVAA) is being depleted, and practices that improve water stewardship have been developed to reduce drawdown. This study assesses how Mississippi Delta producers changed their perceptions of these practices over time. The analysis employs data from two surveys carried-out in 2012 and 2014 of all Mississippi permittees who held an agricultural well permit drawing from the MRVAA. Focusing on water-saving practices, this study found that producer perception of the usability of flowmeters improved over time. About 80% and 90% more producers growing corn and soybeans, respectively, felt that computerized hole selection was highly efficient. In 2014, 38% of corn and 35% of soybean producers believed that shortened furrow length was a highly efficient practice—up from 21% in corn and 24% in soybean producers in 2012. Approval of irrigation automation, moisture probes, and other irrigation technology rose from 75%of producers in 2012 to 88% by 2014. Favorability toward water-saving practices increased overall between the survey years.
