Organisational values as "attractors of chaos": An emerging cultural change to manage organisational complexity

Business organisations are excellent representations of what in physics and mathematics are designated "chaotic" systems. Because a culture of innovation will be vital for organisational survival in the 21st century, the present paper proposes that viewing organisations in terms of "complexity theory" may assist leaders in fine-tuning managerial philosophies that provide orderly management emphasizing stability within a culture of organised chaos, for it is on the "boundary of chaos" that the greatest creativity occurs. It is argued that 21st century companies, as chaotic social systems, will no longer be effectively managed by rigid objectives (MBO) nor by instructions (MBI). Their capacity for self-organisation will be derived essentially from how their members accept a shared set of values or principles for action (MBV). Complexity theory deals with systems that show complex structures in time or space, often hiding simple deterministic rules. This theory holds that once these rules are found, it is possible to make effective predictions and even to control the apparent complexity. The state of chaos that self-organises, thanks to the appearance of the "strange attractor", is the ideal basis for creativity and innovation in the company. In this self-organised state of chaos, members are not confined to narrow roles, and gradually develop their capacity for differentiation and relationships, growing continuously toward their maximum potential contribution to the efficiency of the organisation. In this way, values act as organisers or "attractors" of disorder, which in the theory of chaos are equations represented by unusually regular geometric configurations that predict the long-term behaviour of complex systems. In business organisations (as in all kinds of social systems) the starting principles end up as the final principles in the long term. An attractor is a model representation of the behavioral results of a system. The attractor is not a force of attraction or a goal-oriented presence in the system; it simply depicts where the system is headed based on its rules of motion. Thus, in a culture that cultivates or shares values of autonomy, responsibility, independence, innovation, creativity, and proaction, the risk of short-term chaos is mitigated by an overall long-term sense of direction. A more suitable approach to manage the internal and external complexities that organisations are currently confronting is to alter their dominant culture under the principles of MBV.

The microenvironment in T-cell lymphomas: Emerging themes

Peripheral T-cell lymphomas (PTCLs) are heterogeneous and uncommon malignancies characterized by an aggressive clinical course and a mostly poor outcome with current treatment strategies. Despite novel insights into their pathobiology provided by recent genome-wide molecular studies, several entities remain poorly characterized. In addition to the neoplastic cell population, PTCLs have a microenvironment component, composed of non-tumor cells and stroma, which is quantitatively and qualitatively variable, and which may have an effect on their pathological and clinical features. The best example is provided by angioimmunoblastic T-cell lymphoma (AITL), a designation reflecting the typical vascularization and reactive immunoblastic content of the tumor tissues. In this disease, a complex network of interactions between the lymphoma cells and the microenvironment exists, presumably mediated by the neoplastic T cells with follicular helper T-cell properties. A better understanding of the crosstalk between neoplastic T or NK cells and their microenvironment may have important implications for guiding the development of novel therapies.

Why do emerging economies borrow short term?

We argue that one reason why emerging economies borrow short term is that it is cheaperthan borrowing long term. This is especially the case during crises, as in these episodes therelative cost of long-term borrowing increases. We construct a unique database of sovereignbond prices, returns, and issuances at di¤erent maturities for 11 emerging economies from 1990to 2009 and present a set of new stylized facts. On average, these countries pay a higher riskpremium on long-term than on short-term bonds. During crises, the di¤erence between the tworisk premia increases and issuance shifts towards shorter maturities. To illustrate our argument,we present a simple model in which the maturity structure is the outcome of a risk sharingproblem between an emerging economy subject to rollover crises and risk averse internationalinvestors.

Endogenous bargaining power

We present a novel approach to N-person bargaining, based on the idea thatthe agreement reached in a negotiation is determined by how the directconflict resulting from disagreement would be resolved. Our basic buildingblock is the disagreement function, which maps each set of feasible outcomesinto a disagreement point. Using this function and a weak axiom basedon individual rationality we reach a unique solution: the agreement inthe shadow of conflict, ASC. This agreement may be construed as the limitof a sequence of partial agreements, each of which is reached as a functionof the parties relative power. We examine the connection between ASC andasymmetric Nash solutions. We show the connection between the power ofthe parties embodied in the ASC solution and the bias in the SWF thatwould select ASC as an asymmetric Nash solution.

When Preference Is Not Satisfied but the Individual Is: How Power Distance Affects Person-Job Fit

One aspect of person-job fit reflects congruence between personal preferences and job design; as congruence increases so should satisfaction. We hypothesized that power distance would moderate whether fit is related to satisfaction with degree of job formalization. We obtained measures of job-formalization, fit and satisfaction, as well as organizational commitment from employees (n = 772) in a multinational firm with subsidiaries in six countries. Confirming previous findings, individuals from low power-distance cultures were most satisfied with increasing fit. However, the extent to which individuals from high power-distance cultures were satisfied did not necessarily depend on increasing fit, but mostly on whether the degree of formalization received was congruent to cultural norms. Irrespective of culture, satisfaction with formalization predicted a broad measure of organizational commitment. Apart from our novel extension of fit theory, we show how moderation can be tested in the context of polynomial response surface regression and how specific hypotheses can be tested regarding different points on the response surface.

Why are capital flows so much more volatile in emerging than in developed countries?

The standard deviations of capital flows to emerging countries are 80 percent higher than those to developed countries. First, we show that very little of this difference can be explained by more volatile fundamentals or by higher sensitivity to fundamentals. Second, we show that most of the difference in volatility can be accounted for by three characteristics of capital flows: (i) capital flows to emerging countries are more subject to occasional large negative shocks ( crises ) than those to developed countries, (ii) shocks are subject to contagion, and (iii) the most important one shocks to capital flows to emerging countries are more persistent than those to developed countries. Finally, we study a number of country characteristics to determine which are most associated with capital flow volatility. Our results suggest that underdevelopment of domestic financial markets, weak institutions, and low income per capita, are all associated with capital flow volatility.

Banking as an emerging technology: Hoare's Bank, 1702-1742

London s financial market underwent dramatic change after 1700. More limitedthan Paris or Amsterdam in the seventeenth century, London became the leadingfinancial centre in Europe in the eighteenth century. There is an extensive andgrowing literature on the causes of this change, but comparatively little on thechange itself. This article provides detailed information on the operation of theLondon financial market around 1700 by describing the operations of a nascentLondon bank.

Credit derivatives in emerging markets

Credit Derivatives are securities that offer protection against credit or default risk ofbonds or loans. The credit derivatives emerging market has grown rapidly and creditderivatives are widely used. This paper describes the emerging credit derivativesmarket structure. The current market activity is analyzed through elementary pricingdynamics and the study of the term structure of default risk. Focusing on theperformance of credit derivatives in stress situation, including legal and market risks,we discuss the potential consequences of a debt restructuring in a large emergingmarket borrower. The contribution of credit derivatives to the risk sharing in emergingmarkets is also examined.

The discriminatory power of MALDI-TOF mass spectrometry to differentiate between isogenic teicoplanin-susceptible and teicoplanin-resistant strains of methicillin-resistant Staphylococcus aureus.

To explore the discriminatory power of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) for detecting subtle differences in isogenic isolates, we tested isogenic strains of Staphylococcus aureus differing in their expression of resistance to methicillin or teicoplanin. More important changes in MALDI-TOF MS spectra were found with strains differing in methicillin than in teicoplanin resistance. In comparison, very minor or no changes were recorded in pulsed-field gel electrophoresis profiles or peptidoglycan muropeptide digest patterns of these strains, respectively. MALDI-TOF MS might be useful to detect subtle strain-specific differences in ionizable components released from bacterial surfaces and not from their peptidoglycan network.

Parachlamydia and rhabdochlamydia: emerging agents of community-acquired respiratory infections in children.

T O THE E DITOR-Besides viruses, Mycoplasma pneumoniae and Chlamydia pneumoniae are common causes of community-acquired respiratory infections (CARI) in children. However, the causal agent of CARI remains unknown in many cases [ 1]. Growing evidence suggests that Chlamydia-related bacteria might have a pathogenic role in humans [ 2, 3]. Parachlamydia acanthamoebae and Protochlamydia naegleriophila have been detected in respiratory clinical samples [ 4, 5], and the role of Parachlamydia acanthamoebae in pneumonia is supported by in vitro studies and animal models [ 6]. Rhabdochlamydia crassificans and Rhabdochlamydia porcellionis are intracellular pathogens of arthropods that also belong to the Chlamydiales order [ 7, 8]. A recent analysis suggests that Rhabdochlamydia species might affect morbidity and mortality in premature newborns [ 9], but their role ...

Charting Our Own Course: Today’s Challenges, Tomorrow’s Opportunities, December 2008

The Office of Energy Independence presents Iowa’s second annual energy independence plan, which highlights accomplishments achieved thus far and makes recommendations for the coming year. This plan shows that Iowa has made significant progress in building the foundation for reaching energy independence in just the past year. Continued investment and further efforts will enable Iowa to push toward even greater advances, while creating new jobs and diversifying local economies. With those aims in mind, the state has been investing extensively in the new energy economy. One important example is the Iowa Power Fund, an annual appropriation from the Iowa General Assembly administered by the Office of Energy Independence. In less than one year, the Office has received more than 160 project applications totaling more than $308 million in requests. The projects approved thus far will help advance Iowa’s wind and solar industries, foster new energy efficiency practices, and develop the bio fuels industry for a more economically and environmentally sustainable future. Iowa’s position as a leader in the new energy economy is dependent on the success of the Power Fund, and on the success of this plan. This plan clearly states that Iowa must boldly pursue a strong position in the emerging energy economy worldwide.
