Abstract:
The dynamics of a milling process can significantly influence the surface quality and integrity of the finished part. Accordingly, various researchers have investigated the dynamics of milling processes using a hierarchy of models. Tlusty and Smith (1991) provides a review of these models. In recent years, several other researchers (e.g., Armarego and Deshpande, 1989; Montgomery and Altintas, 1991; Nallakatla and Smith, 1992) have also continued to enhance various aspects of such dynamic models. While these dynamic models provide significant insights into the cutting characteristics of a milling process, their utilization in process design has proven to be elusive. The accuracy of these models, however, depends significantly on the prediction of cutting force characteristics. Under the current state-of-the-art, detailed experimentations using actual set-up are necessary to make such predictions accurately. Experimentally obtained constants can vary widely from one milling situation to another, which in turn, significantly restricts their usefulness as predictive tools for process design.

Abstract:
Externalities are a fundamental aspect of any modern interdependent economy. The fact that agents interact with one another makes it inevitable that their decisions will influence one another directly, in addition to any indirect impact that may occur through the market place. Ever since the earliest stages of the discipline, externalities have been of prime concern to economists, who have long argued that they provide an important motive for (economic) decision making. To cite one prominent example, in The Theory of Moral Sentiments, Adam Smith notes that “Though it is in order to supply the necessities and conveniences of the body that the advantages of external fortune are originally recommended to us, yet we cannot live long in the world without perceiving that the respect of our equals, our credit and rank in the society we live in, depend very much upon the degree in which we possess, or are supposed to possess those advantages. The desire of becoming the proper objects of this respect . . . is perhaps the strongest of all our desires” [Smith (1759, pp. 348–349)]. In modern terminology, Adam Smith is referring to a consumption externality.

This article discusses these reforms from the perspective of China’s ’internal’ dynamics and suggests that Arrighi’s argument has been developed without proper reference to China’s complex realities. As an alternative, the contribution proposes a research-agenda that could better account for these realities.

Abstract:
In 2007, Matthew Philip Gill, a resident of Derbyshire, England, announced the formation of the Latter Day Church of Jesus Christ. He claimed to be acting under angelic direction, and produced a new scripture, the Book of Jeraneck, to usher in his new faith. Gill's church is a restoration of a restoration: he claims to have restored the Mormon movement, which Joseph Smith founded as a restoration of the church Jesus organized, but which Gill claims has fallen into apostasy——particularly its primary iteration, the Church of Jesus Christ of Latter-day Saints (LDS), which Gill was raised in but has abandoned. This article analyzes the relationship between Gill's movement and the LDS church, pointing out the ways in which Gill draws upon the Mormon tradition to claim authority for his new church, but also the ways in which Gill seeks to alter the balance of tension between the LDS church and the culture around it. The article particularly explores Gill's founding narrative, comparing its language, motifs, and forms of spirituality with those of Joseph Smith; the Book of Jeraneck's intertextual relationship with the Book of Mormon; and Gill's story of LDS apostasy.

Abstract:
As mosquito vector plays a significant role in malaria dynamics, a deterministic delay differential equation model10 for the population dynamics of the malaria vector is rigorously analyzed for the non-delay part subject to a new form of vector birth rate function; the Hassell function. For the Hassell function, the model has a non-trivial equilibrium which is locally-asymptotically stable under certain conditions. It is also shown that the non-trivial equilibrium corresponding to this birth function bifurcates into a limit cycle via a Hopf bifurcation. The Maynard-Smith-Slatkin function is better than the Verhulst-Pearl logistic growth function as the former is associated with increased sustained oscillations 9. Again this Maynard- Smith-Slatkin function is more preferable than the Hassell function as the prior one is pertained to more sustained oscillations and holds the analyzed properties for the realistic size of the limiting birth rate.

We obtain the optimal system’s generating operators associated with a generalized Levinson–Smith equation; this one is related to the Liénard equation which is important for physical, mathematical, and engineering points of view. The underlying equation has applications in mechanics and nonlinear dynamics as well. This equation has been widely studied in the qualitative scheme. Here, we treat the equation by using the Lie group method, and we obtain certain operators; using those operators, we characterized all invariants solutions associated with the generalized equation of Levinson Smith considered in this paper. Finally, we classify the Lie algebra associated with the given equation.

Abstract:
The position, size, and shape of the receptive field (RF) of some cortical neurons change dynamically, in response to artificial scotoma conditioning (Pettet & Gilbert, 1992) and to retinal lesions (Chino et al., 1992; Darian-Smith & Gilbert, 1995) in adult animals. The RF dynamics are of interest because they show how visual systems may adaptively overcome damage (from lesions, scotomas, or other failures), may enhance processing efficiency by altering RF coverage in response to visual demand, and may perform perceptual learning. This paper presents an afferent excitatory synaptic plasticity rule and a lateral inhibitory synaptic plasticity rule—the EXIN rules (Marshall, 1995)—to model persistent RF changes after artificial scotoma conditioning and retinal lesions. The EXIN model is compared to the LISSOM model (Sirosh et al., 1996) and to a neuronal adaptation model (Xing & Gerstein, 1994). The rules within each model are isolated and are analyzed independently, to elucidate their roles in adult cortical RF dynamics. Based on computer simulations, the EXIN lateral inhibitory synaptic plasticity rule and the LISSOM lateral excitatory synaptic plasticity rule produced the best fit with current neurophysiological data on visual cortical plasticity in adult animals (Chino et al., 1992; Pettet & Gilbert, 1992; Darian-Smith & Gilbert, 1995) including (1) the retinal position and shape of the expanding RFs; (2) the corticotopic direction in which responsiveness returns to the silenced cortex; (3) the direction of RF shifts; (4) the amount of change in response to blank stimuli; and (5) the lack of dynamic RF changes during conditioning with a retinal lesion in one eye and the unlesioned eye kept open, in adult animals. The effects of the LISSOM lateral inhibitory synaptic plasticity rule during artificial scotoma conditioning are in conflict with those of the other two LISSOM synaptic plasticity rules. A novel “complementary scotoma” conditioning experiment, in which stimulation of two complementary regions of visual space alternates repeatedly, is proposed to differentiate the predictions of the EXIN and LISSOM rules.

Abstract:
The Yangtze River Delta, located in East China, is an important passage on the eastern pathway of the northward migration of fall armyworm Spodoptera frugiperda (Smith) in China, connecting China’s year-round breeding area and the Huang-Huai-Hai summer maize area. Clarifying the migration dynamics of S. frugiperda in the Yangtze River Delta is of great significance for the scientific control and prevention of S. frugiperda in the Yangtze River Delta, even in the Huang-Huai-Hai region and Northeast China. This study is based on the pest investigation data of S. frugiperda in the Yangtze River Delta from 2019 to 2021, combining it with the migration trajectory simulation approach and the synoptic weather analysis. The result showed that S. frugiperda migrated to the Yangtze River Delta in March or April at the earliest, and mainly migrated to the south of the Yangtze River in May, which can be migrated from Guangdong, Guangxi, Fujian, Jiangxi, Hunan and other places. In May and June, S. frugiperda migrated further into the Jiang–Huai region, and its source areas were mainly distributed in Jiangxi, Hunan, Zhejiang, Jiangsu, Anhui and Hubei provinces. In July, it mainly migrated to the north of Huai River, and the source areas of the insects were mainly distributed in Jiangsu, Anhui, Hunan, Hubei and Henan. From the south of the Yangtze River to the north of the Huai River, the source areas of S. frugiperda were constantly moving north. After breeding locally, S. frugiperda can not only migrate to other regions of the Yangtze River Delta, but also to its surrounding provinces of Jiangxi, Hunan, Hubei, Henan, Shandong and Hebei, and even cross the Shandong Peninsula into Northeast China such as Liaoning and Jilin provinces. Trajectory simulation showed that the emigrants of S. frugiperda from the Yangtze River Delta moved northward, westward and eastward as wind direction was quite diverse in June–August. This paper analyzes the migration dynamics of S. frugiperda in the Yangtze River Delta, which has important guiding significance for the monitoring, early warning and the development of scientific prevention and control strategies for whole country.

Abstract:
Pride and Prejudice and Zombies, by Jane Austen and Seth Grahame-Smith, is a literary mashup, the fragmentation procedure of a classic work to graft elements of contemporary pop culture. One of the main questions raised by the novel involves the game of palimpsest inherent to its authorship, since the work was produced through the writing of a dead author (Austen) and a living author (Grahame-Smith). However, it should be noted that the English novelist of the regency period had already experienced intricate dynamics for the attribution of authorship to her own works when it was first published. In this context, the present article analyzes the game between living author and dead letter (or between living work and dead writer), so remarkable in the artistic collaboration that generated Pride and Prejudice and Zombies.

Abstract:
Abstract In their comment, Montgomery and Smith critique the recent study of Heng et al. that revisited the balanced and unbalanced aspects of tropical cyclone (TC) intensification based on diagnostics of a full-physics model simulation using the Sawyer–Eliassen equation. Heng et al. showed that the balanced dynamics reproduced to a large extent the secondary circulation in the full-physics model simulation and concluded that balanced dynamics can well explain TC intensification in their full-physics model simulation. Montgomery and Smith suspect the balanced solution in Heng et al. because the basic-state vortex is not exactly in thermal wind balance in the boundary layer and possibly a too-large diffusivity in the numerical model was used. In this reply, we first indicate that the boundary layer spinup mechanism proposed by Smith et al. is a fast response of the TC boundary layer to surface friction and should not be a major mechanism of TC intensification. We then evaluate the possible effect of imbalance in the basic state in the boundary layer on the balanced solution. The results show that although the removal of the imbalance in the boundary layer leads to about a one-third reduction in the maximum inflow near the surface in the inner-core region, the overall effect on the tangential wind budget is marginal because of other compensations. We also show that both the horizontal and vertical diffusivities in the model used in Heng et al. are reasonable based on previous observational studies. Therefore, we conclude that all results in Heng et al. are valid. Some related issues are also discussed.

Abstract:
Purpose This paper aims to extend the argument of DeNisi & Smith Sockbeson, who called to bridge the gap between feedback-seeking and feedback-giving research. The paper pushes their argument further by suggesting that future feedback research should systematically adopt a dyadic and dynamic approach to enhance the understanding of feedback episodes. Design/methodology/approach This paper reviews previous empirical work in the feedback domain and develops conceptual arguments for linking feedback-seeking and feedback intervention research. Findings Drawing upon previous work, the authors conclude that the current depiction of feedback processes in the literature might have been overly static and one-sided. Furthermore, it is argued that feedback research might have not kept up to date with recent conceptual and methodological developments in dyadic organizational behavior research. Research limitations/implications This paper builds on the argument of DeNisi & Smith Sockbeson, in turn contributing to a more complete picture of how feedback processes unfold in organizations. While this paper profiles a few studies that have begun to bridge the disconnect between feedback-seeking and feedback-giving research, one of its limitations is that it does not adopt a systematic approach in reviewing all potential methodologies. Originality/value This paper provides a first step toward studying feedback episodes as dyadic and dynamic processes. In doing so it helps solving one of the long-standing puzzles in management research namely why feedback interventions are sometimes detrimental to performance.

We thus offer a further exploration of the origins of evolutionary ideas in the history of evolutionary economics. Second, despite the existence of these theoretical continuities, we highlight the differences between the Scottish Enlightenment authors and the modern evolutionary economists on the issue of temporality and the place of history in their reflections.

Abstract:
Ian Smith was one of the world-wide leading researchers into reaction kinetics, energy transfer and molecular dynamics in gas phase systems. He was able to span all of these aspects of collisional behaviour, and to form connections and insights that allowed him to make advances in all of them, advances which have stood the tests of time. His graduate work at the University of Cambridge was followed by academic positions in Cambridge and in Birmingham. He provided new insights into molecular energy transfer by systematically measuring how vibrational frequencies and multipole moments influenced the magnitude of the energy transfer cross sections. In reaction kinetics his detailed work on the OH radical has led to an understanding of the importance of its reactions not only in applied areas such as atmospheric and combustion chemistry, but also in fundamental dynamical studies of radical recombination and the effect of reagent energies on reactive processes. Of particular significance has been his development of both cryogenic and nozzle expansion methods of studying collisional processes at temperatures down to 10 K, with the discovery that reactions without activation barriers can get faster as the temperature decreases. The impact of this work upon astrochemistry has been profound, and has stimulated theoretical explanations of the effect. He was one of the first pioneers in the UK of the use of laser techniques to study collisional processes, using laser-induced fluorescence as a sensitive detection tool, UV laser photolysis to form reactive species and laser pumping to create excited state populations in order to observe their effect upon reaction pathways and vibrational relaxation. Ian was devoted to his family—his wife Sue, their four children and 11 grandchildren. His research collaborators will always remember his scholarship, his unending suggestions of interesting problems to study, his deep integrity and humanity. His legacy lives on with his personal and academic families.

Abstract:
Increment-core data for old-growth red spruce (Picearubens Sarg.) were collected for dendrochonological purposes and compared with second-growth data obtained from USDA Forest Service inventory plots in Maine, New Hampshire, Vermont, and New York. The research objective was to test the hypothesis suggested by J. W. Hornbeck and R. B. Smith (1985, Can. J. For. Res. 15: 1199–1201) that red spruce show reduced growth in the Northeastern United States due to stand dynamics resulting from past logging and insect activity. A graphical approach and a modeling approach based on the Kalman filter were employed. The results indicate that the growth reduction is greater in second-growth stands and that the second-growth stands are converging to an old-growth condition. This supports the stand dynamics hypothesis for second-growth stands.

Abstract. A 3-D numerical global circulation model of the Kronian thermosphere has been used to investigate the influence of polar heating. The distributions of temperature and winds resulting from a general heat source in the polar regions are described. We show that both the total energy input and its vertical distribution are important to the resulting thermal structure. We find that the form of the topside heating profile is particularly important in determining exospheric temperatures. We compare our results to exospheric temperatures from Voyager occultation measurements (Smith et al., 1983; Festou and Atreya, 1982) and auroral H3+ temperatures from ground-based spectroscopic observations (e.g. Miller et al., 2000). We find that a polar heat source is consistent with both the Smith et al. determination of T∞~400 K at ~30° N and auroral temperatures. The required heat source is also consistent with recent estimates of the Joule heating rate at Saturn (Cowley et al., 2004). However, our results show that a polar heat source can probably not explain the Festou and Atreya determination of T∞~800 K at ~4° N and the auroral temperatures simultaneously. Keywords.

Abstract:
This essay is a critical examination of the charge of self-refutation, particularly as leveled by orthodoxy-defending philosophers against those maintaining epistemologically unorthodox, especially relativistic or skeptical, views. Beginning with an analysis of its classic illustration in Plato’s Theaetetus as leveled by Socrates against Protagoras’s “Man is the measure . . ,” the essay considers various aspects of the charge, including its paradigmatic theatrical staging, its frequent pedagogic restaging, its logical and rhetorical structure, its complex emotional and psychological effects, and its apparent cognitive dynamics. After discussion of the comparable structure and dynamics of related self-undoings in myth and drama, the examination of alleged exposures of self-contradiction moves to general observations regarding the recurrent encounter between conviction and skepticism (or orthodox and unorthodox views) and the question of how best to understand the phenomenon of fundamentally clashing and arguably incommensurable beliefs. These encounters and questions are usefully addressed and illuminated, Smith suggests, by constructivist epistemology, contemporary history and sociology of science, and recent work in cognitive theory. In connection with the logically circular question-begging or self-affirmation commonly involved in (alleged) demonstrations of the relativist’s (supposed) self-refutation, Smith gives particular attention to the evidently endemic tendency to cognitive self-stabilization.

Abstract:
The genetic transformation of the higher plant Nicotiana plumbaginifolia to express the protein apoaequorin has recently been used as a method to measure cytosolic free calcium ([Ca2+]i) changes within intact living plants (Knight, M. R., A. K. Campbell, S. M. Smith, and A. J. Trewavas. 1991. Nature (Lond.). 352:524-526; Knight, M. R., S. M. Smith, and A. J. Trewavas. 1992. Proc. Natl. Acad. Sci. USA. 89:4967-4971). After treatment with the luminophore coelenterazine the calcium-activated photoprotein aequorin is formed within the cytosol of the cells of the transformed plants. Aequorin emits blue light in a dose-dependent manner upon binding free calcium (Ca2+). Thus the quantification of light emission from coelenterazine-treated transgenic plant cells provides a direct measurement of [Ca2+]i. In this paper, by using a highly sensitive photon-counting camera connected to a light microscope, we have for the first time imaged changes in [Ca2+]i in response to cold-shock, touch and wounding in different tissues of transgenic Nicotiana plants. Using this approach we have been able to observe tissue-specific [Ca2+]i responses. We also demonstrate how this method can be tailored by the use of different coelenterazine analogues which endow the resultant aequorin (termed semi-synthetic recombinant aeqorin) with different properties. By using h-coelenterazine, which renders the recombinant aequorin reporter more sensitive to Ca2+, we have been able to image relatively small changes in [Ca2+]i in response to touch and wounding: changes not detectable when standard coelenterazine is used. Reconstitution of recombinant aequorin with another coelenterazine analogue (e-coelenterazine) produces a semi-synthetic recombinant aequorin with a bimodal spectrum of luminescence emission. The ratio of luminescence at two wavelengths (421 and 477 nm) provides a simpler method for quantification of [Ca2+]i in vivo than was previously available. This approach has the benefit that no information is needed on the amount of expression, reconstitution or consumption of aequorin which is normally required for calibration with aequorin.

Abstract:
The spatiotemporal dynamics of a diffusive ratio-dependent Holling-Tanner predator-prey model with Smith growth subject to zero-flux boundary condition are investigated analytically and numerically. The asymptotic stability of the positive equilibrium and the existence of Hopf bifurcation around the positive equilibrium are shown; the conditions of Turing instability are obtained. And with the help of numerical simulations, it is found that the model exhibits complex pattern replication: stripes, spots-stripes mixtures, and spots Turing patterns.

Full text
Abstract:
The article brings a brief revision of the two-degree-of-freedom (2-DoF) internal model control (IMC) and the 2-DoF Smith-Predictor-based (SP) control of unstable systems. It shows that the first important reason for distinguishing between these approaches is the limitations of the control action. However, it also reminds that, in addition to the seemingly lucrative dynamics of transients, the proposed approaches can conceal a tricky behavior with a structural instability, which may manifest itself only after a longer period of time. Instead, as one of possible reliable alternatives, two-step IMC and filtered Smith predictor (FSP) design are applied to unstable first-order time-delayed (UFOTD) systems. Firstly, the 2-DoF P controller yielding a double real dominant closed loop pole is applied. Only then the 2-DoF IMC or FSP controllers are designed, providing slightly slower, but more robust transients. These remain stable even in the long run, while also showing increased robustness.

Abstract:
A variety of international macroeconomic models predict a relationship between the real exchange rate and consumption. The empirical evidence in favor of such a relationship is limited, the so-called Backus and Smith puzzle. In this paper, we extend the analysis to allow for nonlinear dynamics and volatility changes across exchange rate regimes. Our findings suggest that long-run relationships in line with standard international business cycle models do exist for many Organization for Economic Co-operation and Development (OECD) countries. Further, Monte Carlo experiments illustrate that the nonlinear models can generate the Backus and Smith and the exchange rate disconnect puzzles. In this paper, we also contribute to the nonlinear real exchange rate literature by establishing a theoretical relationship between volatility and persistence. In accordance with the theoretical results, our empirical findings suggest that the increase in volatility in the post-Bretton Woods era is associated with relatively fast mean reversion of the real rate toward its equilibrium value.

Full text
Abstract:
AbstractGiovanni Arrighi made a remarkably broad-ranging and original contribution to comparative political economy and historical sociology over five decades. His last book shares these qualities. But Adam Smith in Beijing is unfortunately not mainly about the origins and dynamics of Chinese capitalism over the past three decades. It presents Adam Smith not as the apostle of free-market capitalism, but rather of a ‘non-capitalist market society’; and it uses this to make the case that since China’s economic development takes place outside the European/North American capitalist ‘core’, it must, almost by definition, not be capitalist. Markets are conceived here as the instruments of states, yet the theory of the state advanced is severely undeveloped. Arrighi’s argument that China’s economic development is part and parcel of the demise of the US project for establishing itself as the ‘world state’ misinterprets the nature of the US empire as well as misses the extent of China’s integration with US-led capitalist globalisation.

Abstract:
Based on the original Electronically Controlled Pneumatic (ECP) brake system of the heavy-haul freight train and SIMULINK, in this paper we establishes the vehicle longitudinal dynamics model and a new braking control mode (deceleration control) in order to reduce the shock caused by the impulse of the vehicles to the coupler so as to lessen the danger of coupler fracture. The author adopts the Smith-PID control compensating method as the core of the deceleration control so as to control the vehicle longitudinal dynamics model. Furthermore, by calculating the variation of the coupler force and comparing with the results of the original braking force control method, theoretically we can draw conclusion that deceleration control has high feasibility and superiority.

Full text
Abstract:
During the last glacial maximum of east-central Ellesmere Island, trunk glaciers inundated the landscape, entering the Smith Sound Ice Stream. Accelerator mass spectrometry (AMS) dates on individual shell fragments in till indicate that the ice advanced after 19 ka BP. The geomorphic and sedimentary signatures left by the trunk glaciers indicate that the glaciers were polythermal. The configuration and chronology of this ice is relevant to the reconstruction of ice core records from northwestern Greenland, the history of iceberg rafting of clastic sediments to northern Baffin Bay, the reopening of the seaway between the Arctic Ocean and Baffin Bay, and the regional variability of arctic paleoenvironments. Deglaciation began with the separation of Ellesmere Island and Greenland ice at fiord mouths ~8-8.5 ka BP. Ice reached fiord heads between 6.5 and 4.4 ka BP. Trunk glacier retreat from the fiords of east-central Ellesmere Island occurred up to 3000 years later than in west coast fiords. This later retreat was favoured by (1) impoundment by the Smith Sound Ice Stream in Kane Basin until ~8.5 ka BP, which moderated the impact of high summer melt recorded in nearby ice cores between ~11.5 and 8.5 ka BP; (2) the shallow bathymetry and narrowness (<2 km) of the east coast fiords, which lowered calving rates following separation of Innuitian and Greenland ice; and (3) the likelihood of higher precipitation along east Ellesmere Island. Glaciers throughout the field area readvanced during the late Holocene. The greater advance of coastal glaciers is attributed to their proximity to the North Water polynya in Baffin Bay.

Abstract:
The article presents the research results of the effect of post-harvest treatment with Phytomag preparation of fruits of 21 apple tree varieties of domestic and foreign breeding on their storability and quality. The purpose of the research is to determine the effectiveness of the combined effect of such technological techniques as post-harvest fruit treatment with Phytomag preparation and their storage in conventional (CGD) and regulated (RGD) gas dynamics on the formation of quality and storability of apples grown in the Crimea. The data obtained showed that the treatment of fruits with an ethylene inhibitor Phytomag during storage in conventional and regulated gas dynamics reduces losses, depending on the variety, by 1.5-1.8 times. It is established that the processed fruits retain their original marketable appearance, have high quality components during the entire storage period and after opening the refrigerating chambers, selling the fruits and bringing them to the consumer. It is proved that in the conditions of the Crimea such varieties as Tavria, Krymskoye Zimnee, Krymskoye, Orion, Kimmeria, Brebern, Fuji, Idared, Pink Lady can be successfully stored in a conventional gas dynamic with post-harvest treatment with preparation inhibiting ethylene synthesis. The advantage of storage in regulated gas dynamic was shown by the varieties Aromat Kryma, Predgornoye, Golden Delicious, Crispin, Granny Smith, Glouster, Gala, Jonagold.

Abstract:
In Mexico, center of domestication of prickly pear cactus species (also called “nopales”) few studies exist on insects associated with this crop. The studies are scantier on ants, since the majority are not considered to be pest. For this motive, the population dynamics of the ants was studied in experimental prickly pear crop in the installation of Colegio de Postgraduados, Mexico. The sample was fortnightly performed from February 2013 to March 2014. Ants were gathered with pitfall traps and arboreal traps, all of them with three baits and others without bait. Also recorded raiding, the nests in crop and inside to the cladodes. We collected a total of 10,953 individuals (74 % on ground and 26% on prickly pear cladodes), and seven species were determined: Hypoponera opacior (Forel), Neivamyrmex nigrescens (Cresson), Pogonomyrmex barbatus (Smith), Linepithema humile (Mayr), Camponotus atriceps (Smith), Pheidole obtusospinosa Forel and Monomorium minimum (Buckley). The last four were more abundant and frequent. We discuss the presence and nesting of ants in crop and their association with other insects of prickly pear crop.

Abstract:
Ever since David Landes's seminal work on the French family firm and the interplay of culture and economics, French business history has wrestled with the question of French particularism and the role of family enterprise in determining business outcomes. For well over a quarter of a century, historians have challenged or qualified Landes's arguments, first by pointing to successful family enterprises in France or elsewhere, second by reassessing French economic performance in modern times, and third by identifying other factors to explain slower growth in macro or micro terms. Robert J. Smith's thought-provoking study of Bouchayer et Viallet, a medium-sized French firm that rose and fell on family leadership and culture, squarely confronts, once again, the issue of family influence on business success and failure. Combining access to family papers with an astute appraisal of personality and context, Smith has produced a first-rate inquiry into the dynamics of family business firms. Mindful of the fact that family firms still account for a predominant part of GNP, but that few family firms continue as such for more than several generations, Smith asks how family control and values contributed to the success of Bouchayer et Viallet yet also braked growth at a middling level and ultimately undermined the continuity of the company. Intended as a case study in the trajectory of family enterprise, Smith weaves together business, family, and cultural history in exemplary ways that will benefit practitioners of all three fields and that demonstrate the value of the first approach for studying and writing the second and the third.
