Chinese Enterprise, Transnationalism and Identity (Chinese Worlds)

Book Description

Chinese Enterprise, Transnationalism, and Identity focuses on one ethnic community--the Chinese--and examines the variety of issues surrounding enterprise development from national and transnational perspectives, starting with the role played by Chinese entrepreneurs in the 1997 Asian financial crisis.

Using empirical evidence and theoretical debate the contibutors argue that Chinese enterprise is accelerated by intra-ethnic competetion, rather than intra-ethnic co-operation, and that businessmen work in their own interest, not that of the Chinese community, as other literature dealing with the subject suggests. Themes which this book radically reviews include:

* Culture and networks
* Family business
* Ownership and control
* Transnationalism and identity

By carefully tracing the emergence of new generations the contributors suggest that new forms of ethnic identification and of national identity and affiliation have emerged. With its combined analysis of ethnic minorities in Asia and of Chinese business this book will appeal to scholars of Asian and Business studies alike.

A lot of money for a flawed book.......2006-11-05

Taking a culturalist view in my research and teaching, this anti-culturalist book caught my eye. It starts from the premise that culture has no influence on business and management, and fails to prove it, sometimes attempting to prove the thesis by ignoring culture. All competent researchers are aware that outcomes from data analyses can be tailored to support a premise by what you measure, what results you choose to report, and what you say about them. I pass on the Book Review by Gordon Redding, Euro-Asia and Comparative Research Centre, INSEAD, in 'The China Journal', Jul 2005., Iss. 54; pg. 186, 4 pgs: Redding notes that 'this book flows from commissioned research designed to provide the evidence that culture and common ethnic identity do not determine decision-making in business. The aim and the tone are set unambiguously in the statement that "the assertion we make in this volume is precisely the opposite to the argument adopted in the 'culturalist perspective', i.e. that culture is a determining factor in how ethnic Chinese undertake business ventures and develop their firms" (p. xiv). Note: it is not just that culture is challenged for being proposed as the determining factor; it is not even going to be allowed to be a determining factor. From the outset, we are in the hands of people with a mission, so the warning in the preface is valuable.'

'Overall, the problem with the book is that instead of asking modestly how much of the explanation is economic, how much political, how much cultural, and so on, an absolutist cultural argument is erected as a straw man and savagely bayoneted. I know of almost no culturalists who make the claims of explanatory dominance which are assumed here at the outset and that go back to the original Weberian account. What is needed is not an opposite and clearly announced bias, but a search for fusion, for genuine socio-economics. This book fails to provide it.'

Book Description

While it is easy to assume that the system of criminal justice in nineteenth-century England was not unlike the modern one, in many ways it was very different, particularly before the series of Victorian reforms that gradually codified a system dependent on judge-made precedent. In the first half of the century capital cases often tried almost summarily, with the accused not being adequately represented and without a system of appeal. There were also fundamental differences in procedure and in the rules of evidence, as indeed there were in attitudes towards crime and criminals. David Bentley has provided an account of the nineteenth-century criminal justice system as a whole, from the crimes committed and the classification of offences to the different courts and their procedure. He describes the stages of criminal prosecution -- committal, indictment, trial, verdict and punishment -- and the judges, lawyers and juries, highlighting significant changes in the rules of evidence during the century. He looks at the reform of the old system and assesses how far it was brought about by lawyers themselves and how far by external forces. Finally, he considers the fairness of the system, both as seen by contemporaries and in modern terms.

Book Description

Paul Nurse focuses on four discoveries in 'The Great Ideas of Biology': the cell, the gene, evolution by natural selection, and life as chemistry. The development of good microscopes made the discovery of the cell possible, although it was not until the later nineteenth century that it was accepted that all living organisms, regardless of their complexity, emerged from a single cell. The discovery of the gene followed the idea that all living organisms have the ability to reproduce and generate offspring that resemble their parents. Gregor Mendel's crosses with plants and analyses of the outcomes in the 1860s led him to become the father of genetics, and in the mid-twentieth century DNA was shown to be the genetic material. Natural selection, the idea of the survival of the fittest, is one of the best-known ideas of biology, proposed by Charles Darwin in 1859. The idea that many of life's activities can be understood in terms of chemistry had its origins in studies of fermentation, and biochemistry was born when it was shown that an enzyme from yeast cells, i.e. a living organism, was responsible for the chemical reactions that turned grape juice into alcohol. At that point it was postulated that cells should be understood as a chemical machine. Paul Nurse concludes that the current challenge for biologists is to focus on biological organization which works on a range of levels, from cells through to organisms and ecosystems.

Book Description

The determination of the concentrations of molecules in samples has long been an important application of spectroscopy. In the last 20 years advances in algorithms, computers, instruments, and software have led to a growing interest in this field. These developments mean samples and analytes that were once considered intractable are increasingly yielding usable calibrations. The purpose of this book is to give readers, without an advanced math background, a thorough grounding in the theory and practice of modern quantitative spectroscopic analysis. The author has placed great emphasis on providing the reader with everything they need to know to obtain a fundamental understanding of quantitative spectroscopy.

· Relevant theory is explained in an easy to understand, conversational style.
· Actual spectroscopic data and calibrations are used throughout the book to show how real world calibrations are achieved.
· The complexities of Factor Analysis (PCR/PLS) algorithms are explained in pictures and words, making them understandable for all.
· Written from a spectroscopic rather than a mathematical point of view.
· Relevant theory is interspersed with practical discussions in order to make difficult concepts easier to comprehend
· It is a comprehensive introduction for novices, and an excellent reference for experts.
· Topics on spectroscopy are included to emphasize its importance in quantitative spectroscopy

Book Description

The present book is the second edition of Amikam Aharoni's Introduction to the Theory of Ferromagnetism, based on a popular lecture course. Like its predecessor, it serves a two-fold purpose: First, it is a textbook for first-year graduate and advanced undergraduate students in both physics and engineering. Second, it explains the basic theoretical principles on which the work is based for practising engineers and experimental physicists who work in the field of magnetism, thus also serving to a certain extent as a reference book. For both professionals and students the emphasis is on introducing the foundations of the different subfields, highlighting the direction and tendency of the most recent research. For this new edition, the author has thoroughly updated the material especially of chapters 9 ('The Nucleation Problem') and 11 ('Numerical Micromagnetics'), which now contain the state of the art required by students and professionals who work on advanced topics of ferromagnetism. From reviews on the 1/e: '... a much needed, thorough introduction and guide to the literature. It is full of wisdom and commentary. Even more, it is Amikam Aharoni at his best - telling a story... He is fun to read... The extensive references provide an advanced review of micromagnetics and supply sources for suitable exercises... there is much for the student to do with the guidance provided by Introduction to the Theory of Ferromagnetism.'

Book Description

In Living Up to the Ads Simone Weil Davis examines commodity culture’s impact on popular notions of gender and identity during the 1920s. Arguing that the newly ascendant advertising industry introduced three new metaphors for personhood—the ad man, the female consumer, and the often female advertising model or spokesperson—Davis traces the emergence of the pervasive gendering of American consumerism.
Materials from advertising firms—including memos, manuals, meeting minutes, and newsletters—are considered alongside the fiction of Sinclair Lewis, Nella Larsen, Bruce Barton, F. Scott Fitzgerald, and Zelda Fitzgerald. Davis engages such books as Babbitt, Quicksand, and Save Me the Waltz in original and imaginative ways, asking each to participate in her discussion of commodity culture, gender, and identity. To illuminate the subjective, day-to-day experiences of 1920s consumerism in the United States, Davis juxtaposes print ads and industry manuals with works of fiction. Capturing the maverick voices of some of the decade’s most influential advertisers and writers, Davis reveals the lines that were drawn between truths and lies, seduction and selling, white and black, and men and women.
Davis’s methodology challenges disciplinary borders by employing historical, sociological, and literary practices to discuss the enduring links between commodity culture, gender, and identity construction. Living Up to the Ads will appeal to students and scholars of advertising, American studies, women’s studies, cultural studies, and early-twentieth-century American history.

Book Description

Robert Weinberg and Bradley Berman's carefully documented and extensively illustrated book explores the Soviet government's failed experiment to create a socialist Jewish homeland. In 1934 an area popularly known as Birobidzhan, a sparsely populated region along the Sino-Soviet border some five thousand miles east of Moscow, was designated the national homeland of Soviet Jewry. Establishing the Jewish Autonomous Region was part of the Kremlin's plan to create an enclave where secular Jewish culture rooted in Yiddish and socialism could serve as an alternative to Palestine. The Kremlin also considered the region a solution to various perceived problems besetting Soviet Jews. Birobidzhan still exists today, but despite its continued official status Jews are a small minority of the inhabitants of the region. Drawing upon documents from archives in Moscow and Birobidzhan, as well as photograph collections never seen outside Birobidzhan, Weinberg's story of the Soviet Zion sheds new light on a host of important historical and contemporary issues regarding Jewish identity, community, and culture. Given the persistence of the "Jewish question" in Russia, the history of Birobidzhan provides an unusual point of entry into examining the fate of Soviet Jewry under communist rule.

Interesting facts.......2000-04-20

Birobidjan of course failed to be the capital of Sovet Jewry(did Brighton Beach, Brooklin win this title?) The book is based onfacts, and facts usually can scare more than any fiction. I don't feel like the author makes the most of the facts. I do feel that the author is too soft in his judgement, I guess presenting the facts is always easier than providing a personal outlook.

This book is filled with plenty of "snack recipes". It is a great way to put students into the application and synthesis levels of learning, and a great way to move beyond worksheets in the classroom. Some of the activities will need assistance from an adult, but they are so interesting that the adult will be impressed by the results.

Description:
Magnetic susceptibility and grain size records from two continuous red-clay and loess-palaeosol sequences on the Chinese Loess Plateau have been generated to investigate the evolution and variability of the East Asian monsoon (EAM) during the late Pliocene and Pleistocene. Tuning the grain size records to orbital obliquity and precession yields an improved astronomical timescale for the loess-palaeosol sequence (0-2.6Ma), and an extended age model for the upper red-clay formation (2.6-3.6Ma). This timescale indicates older ages for a number of the magnetic polarity boundaries, consistent with lock-in depth offsets in loess sequences. Good site-to-site correlation enables generation of stacked grain size and susceptibility records spanning the last 3.6Myr. These records indicate that monsoon evolution since the late Pliocene can be subdivided into three phases: 0-1.25, 1.25-2.72 and 2.72-3.4Ma; each phase is characterized by unique amplitude and frequency characteristics for both summer monsoon (magnetic susceptibility) and winter monsoon (grain size). Spectral analyses of the stacked monsoon proxies indicate that characteristics of both the summer and winter monsoons are dominated mainly by variance in the eccentricity (410- and 100-kyr), obliquity (41-kyr) and precession (23- and 19-kyr) bands over the past 3.4Myr, implying a non-linear response of the long-term EAM evolution to orbital and glacial forcing.

Description:
Current research on stable carbon isotopes of the Chinese loess is reviewed. The stable carbon isotopic composition of soil organic matter (SOM) (@d^1^3C"o"r"g) of paleosols formed during interglacials is more positive than that within loess accumulated during glacials. Spatially, it becomes progressively more negative from the eastern Chinese Loess Plateau (CLP) to the western. However, stable carbon isotopic composition of pedogenic carbonates (@d^1^3C"c"a"r"b) from the same sequence produces an opposing trend, both temporally and spatially, and variation differs from expectations under conditions of equilibrium. This indicates that @d^1^3C"c"a"r"b in the Chinese loess cannot be used to reconstruct the relative proportion of C"3/C"4 plants in past ecological communities. Furthermore, use of @d^1^3C"c"a"r"b to reconstruct the expansion of C"4 plants in older Tertiary red clay deposits is considered unreliable. We believe @d^1^3C"c"a"r"b may act as an indirect indicator of vegetation density, following on changes in moisture supply controlled by the intensity of the Asian Summer Monsoon, but conclude that full understanding of the paleoclimatic significance of @d^1^3C"c"a"r"b in the Chinese loess and underlying Tertiary red clay requires better understanding of modern isotopic processes.

Description:
Chinese loess offers favourable conditions for identifying evidence for high-resolution climatic changes. Previous studies have examined orbital scale climatic cycles and the other shorter time scale climatic oscillations, similar to the recorded glacial instability in deep-sea cores. In this study, we focus on examining the high-resolution palaeoclimatic records in the northwestern Loess Plateau, where the dust accumulation rate is high and the loess-soil sequences are highly sensitive to the shifting pattern of the East Asian monsoon system. Our results of magnetic susceptibility and particle size analysis from the northwestern Loess Plateau reveal well-defined half-precessional cycles during the last interglaciation, culminating at approximately 122,000, 111,000, 100,000, 88,000, and 79,000yr. These variations are a direct response to the low-latitude forcing through its modulation on the East Asian summer monsoon. In this context, the East Asian summer monsoon has played an important role in conveying climatic signals from tropical Pacific to the middle latitude areas.

Description:
We present optical ages for well preserved loess deposits along the Qilian Shan, a 500-km-long mountain belt forming the tectonically active northeastern margin of the Tibetan Plateau. Loess on tectonically controlled fill terraces along the Shiyou and Baiyong rivers was dated by applying the single-aliquot regeneration (SAR) technique to coarse-grained (90-160@mm) quartz samples. Additional measurements on polymineralic fine-grained (5-10@mm) samples were carried out to allow a comparison between various optical dating techniques currently in use. The results demonstrate that (i) loess accumulation started between 13 and 11ka B.P., continuing to the present, (ii) mean loess accumulation rates range between ~9 and ~16cmka^-^1, and (iii) Holocene loess is not restricted to certain sites only, but is a prevalent phenomenon along the Qilian Shan mountain front. The absence of loess deposits of Late Pleistocene age is a result of a combination of cold and dry climate conditions, strong winds, and the absence of a vegetation cover during the last glacial period. Only with the change to a warmer and moister climate at the onset of the Holocene did a plant cover develop, which acted as a dust trap, thus initiating the formation of loess.

Description:
Multi-disciplinary investigations were carried out in a Holocene eolian loess-soil profile in the centre of the Chinese Loess Plateau at the transition between the arid Mongolian steppe and the semi-arid mixed forest, and also the transitional zone between nomadism and the rain-fed cereal agriculture in history. The cultural remains of an earliest rain-fed cereal agriculture, and also the remains of a Bronze Age nomadic community identified in the profile indicate that the regional emergence and decline of the rain-fed cereal agriculture was closely connected with the change in dust accumulation and soil formation. The climatic proxies derived from the profile show that monsoonal climatic variation, especially precipitation behind the pedogenic change, was ultimately responsible for the cultural and land-use change over the Loess Plateau. Increased precipitation brought on by southeast monsoon, conditioned the domestication and cultivation of millets in the southern part of the region during 8000-7000 a BP at the beginning of the Holocene climatic optimum. Sufficient precipitation and the well-developed fertile soils facilitated the expansion of millets cultivation to the northern Loess Plateau and the southern Mongolian Plateau between 7000 a BP and 3600 a BP. Reduced precipitation and deteriorated land-use conditions because of intensified northwest monsoon at the end of the Holocene climatic optimum caused a regional desertion by the arable farming communities and the invasion of the nomads in the northern part of the Loess Plateau from ca. 3600 a BP during the Bronze Age. Monsoonal climatic change and the resultant pedogenic change dramatically affected the cultural development over the Loess Plateau during the Holocene.

Description:
Low-field magnetic susceptibility has been widely used to determine the pedostratigraphy of the Chinese loess/paleosol sequences. However, uncertainties remain in correlating between the loess magnetic susceptibility and the marine oxygen isotope records because susceptibility variations are affected by both global and local paleoclimatic changes. To provide a more sound paleoclimatic interpretation of magnetic susceptibility variations, age models across Marine Oxygen Isotope Stage (MIS) 5 for the Jiuzhoutai (JZT) and Yuanbao (YB) sections, western Chinese Loess Plateau, were constructed through an integrated approach by linking the major pedostratigraphic boundaries of the loess profiles to the SPECMAP oxygen isotope curve, and by correlating relative magnetic paleointensity records with both the SINT800 global paleointensity stack from marine sediments and ^3^6Cl records from the GRIP ice core. Results indicate good correlation of SIRM"6"0"m"T (a residual remanence of saturation isothermal remanent magnetization after a 60mT alternating field demagnetization) variations between these two sites, which agree well with fluctuations in subtropical Atlantic sea surface temperatures. All cooling events recorded by ice-core and Atlantic marine sediments within MIS5 have counterparts in SIRM"6"0"m"T. SIRM"6"0"m"T is partially controlled by the degree of low-temperature oxidation, which is strongly temperature dependent. However, strong pedogenesis can decrease SIRM"6"0"m"T due to further oxidation of partially oxidized magnetites above some critical points. Therefore, we propose that SIRM"6"0"m"T is best suited to record paleotemperature changes in loess profiles from the western Chinese Loess Plateau, where pedogenesis is the weakest. Furthermore, by inter-profile correlation between the YB and JZT sections, we note that the seemingly uniform sub-paleosol unit with a broad susceptibility peak (previously assigned to MIS5c) between ~34.4 and ~37.4m in the YB profile actually consists of two independent units (lower part of S1L1/MIS5b and S1S2/MIS5c). This indicates that susceptibility values can be strongly affected by local factors (e.g., mainly precipitation). Therefore, beside the simplistic traditional paleoclimatic interpretation of variations in loess susceptibility involving only cold/dry and warm/humid scenarios, cold/humid and warm/dry scenarios should also be considered.

Description:
The grain-size distributions (GSDs) of loess-paleosol sequences may provide valuable information on provenance, transport and paleoclimate variability, and consequently, a wide range of methods to extract genetic information from loess GSDs has been proposed. Here it is shown that a genetically meaningful decomposition of a series of Late Quaternary loess grain-size records extending across the Chinese Loess Plateau can be accomplished with the end-member modelling algorithm (EMMA). The unmixing results in conjunction with loess accumulation rate estimates reveal that two contrasting dust supply patterns were active over the Loess Plateau during the last glacial-interglacial cycle: (i) a background sedimentation pattern that was dominant during interglacial periods, especially over the central and southern parts of the Loess Plateau, is reflected by the constant flux of the fine-grained loess component, (ii) an episodic, highly variable dust input pattern, that was dominant during glacial periods throughout the Loess Plateau and noticeable during interglacial periods mainly over the northern Loess Plateau and almost disappearing over the southern Loess Plateau, is reflected in the admixture of two coarse-grained loess components. A genetic interpretation and the paleoclimatic significance of the mixing model are provided by comparison of the modelled end members with modern dust samples in terms of their GSD and flux rates.

Description:
High resolution records for long chain n-alkane and n-alkanol biomarkers have been obtained by extraction of sediments from the profiles of Luochan (0-36ka) and Xunyi (0-170ka) on the Chinese Loess Plateau (CLP). The two records are similar where they overlap over the last 36ka. At Xunyi, distributions of the n-alkane and n-alkanol homologues remain relatively constant over the full 170kyr. The n-alkanes are characterized by high odd over even carbon number preference and predominance of the C"3"1n-alkane, whereas the n-alkanols are dominated by even over odd carbon numbers and by the C"2"8n-alkanol. An Alkane Index [A.I., C"3"l/(C"2"9+C"3"1)] and an Alkanol Index [Alc.I., C"3"0/(C"2"8+C"3"0)] are both positively related with magnetic susceptibility of the sediment, with higher values during interglacials. A Lipid Index, L.I., averaging the normalized Alkane and Alkanol indices, gives a measure of changing vegetation for palaeo-environmental construction. A further useful index is provided by the @d^1^3C value of the most abundant n-alkane, C"3"1, after adjustment for the calculated effect of the estimated atmospheric pCO"2 and precipitation. The record of this index over the last 170kyr, which varies from -36 to -32%%, indicates that the vegetation on the CLP has been mainly C"3 plants and became even more so in the glacial periods (especially MIS 6 and 2) as the minor population of warm season grasses (C"4) favored in interglacial times declined when temperatures fell. The lipid distributions and carbon isotope values are in general accord with the pollen and phytolith evidence recorded for the Yuan areas of the CLP in indicating steppe or meadow-steppe vegetation, with abundant cold season grasses (C"3) and some herbs, bushes and trees, especially in glacial times.
