    Balancing Hamiltonian and Jeffersonian Contradictions within Organizations

    Get PDF
    This article describes how institutions get infused with competing logics and analyzes how such competing logics might aid the design of contemporary organizations. It does so by exploring the contrasting views of American founders Alexander Hamilton and Thomas Jefferson on the issues they confronted in the years leading up to and after the United States\u27 independence from the British. Their views have had a lasting influence on the character and efficacy of the U.S. government. Although Hamilton and Jefferson contemplated issues related to the governance of the United States, the authors argue that their writings offer insights that can be useful to students of organizational design. They identify four influential ideas from the writings of Hamilton and Jefferson and discuss their implications for organizational design

    Over the past few decades, India has become one of the world’s most vibrant economies (Chari & Banalieva, 2015). While the first forty years after India’s independence in 1947 was characterized by a sluggish annual growth rate (of approximately 3%), economic reforms initiated in 1991 have resulted in the GDP growing at a rate of around 6.8% in the last quarter century (Chari & Banalieva, 2015;McCloskey, 2010). Conversely, while the pre-reform institutional environment generally underemphasized and undermined entrepreneurial and innovative activity (Bardhan, 1994; Baumol, Litan, & Schramm, 2009;Sivaraman, 1991), the post-reform period has been characterized by a much wider acceptance of the value of innovation and entrepreneurship. Moreover, many Indian firms and entrepreneurs have emerged as global leaders in information technology (IT) services, auto, steel and generic drug production as well as medical services (Chari & Banalieva, 2015). India’s emergence as a significant player in the global business landscape has been accompanied by a boom in discourse about Indian economy and management, with academics, journalists, consultants and managers alike studying and chronicling these in numerous articles and books (e.g. Das, 2000;Nilekani, 2008; Chandler & Zainulbhai, 2013; Sharma, 2015)—all of these constituting the first draft of this exciting phase in India’s development

    Transitional Entrepreneurship: Unleashing Entrepreneurial Potential Across Numerous Challenging Contexts

    Get PDF
    Transitional entrepreneurship refers to the practices of entrepreneurs from communities facing adversity who navigate substantial life transitions as they launch and manage new ventures in response to various changes and challenges in their environment. Entrepreneurship is not only a critical driver of economic growth and social development (Ahlstrom et al., 2019; McCloskey, 2010) but can also represent a life-changing transition for most, if not all, of the entrepreneurs themselves. Transitional entrepreneurship entails strategic pivots or transformations that enable entrepreneurs to adapt and thrive in evolving circumstances. In this regard, transitional entrepreneurship research focuses on entrepreneurs from veterans, minorities, immigrants, refugees, women, historically marginalized groups and economically distressed communities. The major goal of this special issue is to draw attention to the endeavors of entrepreneurs from these communities and to pull together some of the disparate research on the important topic of transitional entrepreneurship

    Limitations of variable number of tandem repeat typing identified through whole genome sequencing of Mycobacterium avium subsp. paratuberculosis on a national and herd level

    Get PDF
    Background: Mycobacterium avium subsp. paratuberculosis (MAP), the causative bacterium of Johne’s disease in dairy cattle, is widespread in the Canadian dairy industry and has significant economic and animal welfare implications. An understanding of the population dynamics of MAP can be used to identify introduction events, improve control efforts and target transmission pathways, although this requires an adequate understanding of MAP diversity and distribution between herds and across the country. Whole genome sequencing (WGS) offers a detailed assessment of the SNP-level diversity and genetic relationship of isolates, whereas several molecular typing techniques used to investigate the molecular epidemiology of MAP, such as variable number of tandem repeat (VNTR) typing, target relatively unstable repetitive elements in the genome that may be too unpredictable to draw accurate conclusions. The objective of this study was to evaluate the diversity of bovine MAP isolates in Canadian dairy herds using WGS and then determine if VNTR typing can distinguish truly related and unrelated isolates.<p></p> Results: Phylogenetic analysis based on 3,039 SNPs identified through WGS of 124 MAP isolates identified eight genetically distinct subtypes in dairy herds from seven Canadian provinces, with the dominant type including over 80% of MAP isolates. VNTR typing of 527 MAP isolates identified 12 types, including “bison type” isolates, from seven different herds. At a national level, MAP isolates differed from each other by 1–2 to 239–240 SNPs, regardless of whether they belonged to the same or different VNTR types. A herd-level analysis of MAP isolates demonstrated that VNTR typing may both over-estimate and under-estimate the relatedness of MAP isolates found within a single herd.<p></p> Conclusions: The presence of multiple MAP subtypes in Canada suggests multiple introductions into the country including what has now become one dominant type, an important finding for Johne’s disease control. VNTR typing often failed to identify closely and distantly related isolates, limiting the applicability of using this typing scheme to study the molecular epidemiology of MAP at a national and herd-level.<p></p&gt

    A GA2LEN Study

    Background: Flavonoids exert anti-inflammatory properties and modulate oxidative stress in vitro, suggesting a protective effect on lung function, but epidemiological studies examining this association are scarce. Methods: A stratified random sample was drawn from the GA2LEN screening survey, in which 55,000 adults aged 15 to 75 answered a questionnaire on respiratory symptoms. Post-bronchodilator spirometry was obtained from 2850 subjects. Forced vital capacity (FVC), the ratio between the forced exhaled volume in 1 second (FEV1) and FVC (FEV1/FVC), FVC below lower limit of normal (FVC < LLN), and FEV1/FVC < LLN were calculated. Intake of the six main subclasses of flavonoids was estimated using the GA2LEN Food Frequency Questionnaire. Adjusted associations between outcomes and each subclass of flavonoids were examined with multivariate regressions. Simes’ procedure was used to test for multiple comparisons. Results: A total of 2599 subjects had valid lung function and dietary data. A lower prevalence of FVC < LLN (airway restriction) was observed in those with higher total flavonoid (adjusted odds ratio (aOR), higher vs. lowest quintile intake 0.58; 95% Confidence Interval (CI) 0.36, 0.94), and pro-anthocyanidin intakes (aOR 0.47; 95% CI 0.27, 0.81). A higher FEV1/FVC was associated with higher intakes of total flavonoids and pro- anthocyanidins (adjusted correlation coefficient (a β-coeff 0.33; 0.10, 0.57 and a β-coeff 0.44; 95% CI 0.19, 0.69, respectively). After Simes’ procedure, the statistical significance of each of these associations was attenuated but remained below 0.05, with the exception of total flavonoids and airway restriction. Conclusions: This population-based study in European adults provides cross-sectional evidence of a positive association of total flavonoid intake and pro-anthocyanidins and ventilatory function, and a negative association with spirometric restriction in European adults.

    Deep Space Network Antenna Logic Controller

    Get PDF
    The Antenna Logic Controller (ALC) software controls and monitors the motion control equipment of the 4,000-metric-ton structure of the Deep Space Network 70-meter antenna. This program coordinates the control of 42 hydraulic pumps, while monitoring several interlocks for personnel and equipment safety. Remote operation of the ALC runs via the Antenna Monitor & Control (AMC) computer, which orchestrates the tracking functions of the entire antenna. This software provides a graphical user interface for local control, monitoring, and identification of faults as well as, at a high level, providing for the digital control of the axis brakes so that the servo of the AMC may control the motion of the antenna. Specific functions of the ALC also include routines for startup in cold weather, controlled shutdown for both normal and fault situations, and pump switching on failure. The increased monitoring, the ability to trend key performance characteristics, the improved fault detection and recovery, the centralization of all control at a single panel, and the simplification of the user interface have all reduced the required workforce to run 70-meter antennas. The ALC also increases the antenna availability by reducing the time required to start up the antenna, to diagnose faults, and by providing additional insight into the performance of key parameters that aid in preventive maintenance to avoid key element failure. The ALC User Display (AUD) is a graphical user interface with hierarchical display structure, which provides high-level status information to the operation of the ALC, as well as detailed information for virtually all aspects of the ALC via drill-down displays. The operational status of an item, be it a function or assembly, is shown in the higher-level display. By pressing the item on the display screen, a new screen opens to show more detail of the function/assembly. Navigation tools and the map button allow immediate access to all screens

    Developing research priorities for palliative care of people with intellectual disabilities in Europe: a consultation process using nominal group technique

    Get PDF
    BACKGROUND: Empirical knowledge around palliative care provision and needs of people with intellectual disabilities is extremely limited, as is the availability of research resources, including expertise and funding. This paper describes a consultation process that sought to develop an agenda for research priorities for palliative care of people with intellectual disabilities in Europe. METHODS: A two-day workshop was convened, attended by 16 academics and clinicians in the field of palliative care and intellectual disability from six European countries. The first day consisted of round-table presentations and discussions about the current state of the art, research challenges and knowledge gaps. The second day was focused on developing consensus research priorities with 12 of the workshop participants using nominal group technique, a structured method which involved generating a list of research priorities and ranking them in order of importance. RESULTS: A total of 40 research priorities were proposed and collapsed into eleven research themes. The four most important research themes were: investigating issues around end of life decision making; mapping the scale and scope of the issue; investigating the quality of palliative care for people with intellectual disabilities, including the challenges in achieving best practice; and developing outcome measures and instruments for palliative care of people with intellectual disabilities. CONCLUSIONS: The proposal of four major priority areas and a range of minor themes for future research in intellectual disability, death, dying and palliative care will help researchers to focus limited resources and research expertise on areas where it is most needed and support the building of collaborations. The next steps are to cross-validate these research priorities with people with intellectual disabilities, carers, clinicians, researchers and other stakeholders across Europe; to validate them with local and national policy makers to determine how they could best be incorporated in policy and programmes; and to translate them into actual research studies by setting up European collaborations for specific studies that require such collaboration, develop research proposals and attract research funding
