A kameralizmus a 16-18. századi német gyakorlati államtudomány és egyetemi tantárgy volt, amely összefoglalta a hivatalnokok képzéséhez szükséges elméleti és gyakorlati gazdasági ismereteket. Felfogása szerint az alattvalók jóléte és boldogsága feltétele az uralkodó gazdagságának, de az alattvalók önmaguktól nem képesek utat találni ehhez a boldogsághoz, szükség van az állandó külső irányításra. Igazgatásközpontúsága és egyetemi intézményesülése miatt nem tekinthető a merkantilizmus helyi változatának. Az 1840 és 1945 közötti német történeti iskola hagyományos ábrázolása több mint egy évszázadon át a német és a neoklasszikus tradíció szembenállását hangsúlyozta, kiemelve az organicizmus, a fejlődésgondolat és az egyediség jelentőségét, a szociális kérdés fontosságát, illetve a deduktív módszer és a gazdaság változatlan törvényeinek tagadását. A modern rekonstrukciók a történeti iskolát a posztklasszikus válságra adott egyik európai válaszként fogják fel, amely a történelemből levont, empirikusan megalapozott induktív alternatívát kínált. Az 1871-től kialakult osztrák iskola a neoklasszikus paradigmának egyszerre volt alkotórésze és versenytársa. A módszertani individualizmus, a szubjektivizmus, az idő fontossága, a tudás szerepe, az alternatív költségek elmélete stb. ugyan beépültek a mainstream közgazdaságtanba, de hangsúlyos kiemelésük lehetővé tette, hogy a társadalomelméleti magyarázat igényét őrző osztrák iskola megtartson valamit önálló beszédmódjából. / === / Cameralism was a practical political science and university subject in 16th–18th century Germany, summarizing the theoretical and practical economic knowledge required in the training of officials. The assumption was that the prosperity of the ruler depended on the welfare and happiness of the subjects, but the subjects themselves were not capable of achieving this happiness without permanent directions from above. Cameralism’s emphasis on administration and university institutionalization means that this approach cannot be seen as a local variant of mercantilism. The traditional account of the German historical school from 1840 to 1945 emphasized for over a century the contrast between the German and the Neoclassical traditions. It underlined the significance of the organic approach, the concept of development and individuality, the importance of the social question, and the denial of the deductive method and unalterable laws of the economy. Modern reconstructions see the historical school as one European response to the post-Classical crisis, offering an inductive alternative grounded empirically on history. The Austrian school formed in 1871 was at once a constituent of the Neoclassical paradigm and a rival to it. Methodological individualism, subjectivism, the importance of time, the role of knowledge, the theory of alternative costs etc. were absorbed into mainstream economics, but the focusing on these issues allowed the Austrian school, in keeping alive its demand for a social-theoretical explanation, to preserve something of an alternative discourse.

Kornai János rendszerparadigma-fogalmából és az ott felsorolt közgazdászok névsorából kiindulva, a tanulmány kiemel néhány mozzanatot ennek eszmetörténeti előzményeiből. A hatvanas évek szociológiai irodalmában időszerűtlennek tartották a nagy elmélet létrehozását, a nyolcvanas évek társadalomtudományában viszont már a hagyományos nagy rendszeralkotás és elbeszélésmód visszatérését méltatták. Adam Smith közgazdaságtanát a társadalmi érintkezés átfogó elmélete részének szánta, amely tartalmazza a jog, politika és erkölcs elveit és történetét. Ezt szemlélteti a kereskedelmi társadalom paradoxonának elemzése és annak bemutatása, hogyan vezetett a fényűzés a szabadság helyreállításához és a rendszeres kormányzat létrejöttéhez. Marx és a német történeti iskola egyaránt törekedett a társadalom történeti fejlődéstörvényeinek feltárására, noha kölcsönösen elutasították egymás felfogásának többi elemét. Schumpeter életművét az a törekvés határozta meg, hogy összekapcsolja az elméleti analízist és a történeti leírást, hogy a gazdasági fejlődés elemzéséből kiindulva megalkossa a társadalmi élet különböző területeinek interdependenciáját bemutató elméletet. / === / The study starts from János Kornai's concept of a system paradigm and the list of economists there to lift certain elements from its antecedents in intellectual history. The sociological writers of the 1960s thought it was inopportune to create a grand theory, while the social scientists of the 1980s were busy celebrating the return of the great traditional system-creating process and its mode of narration. Adam Smith presented his economics as part of a comprehensive theory of social organization that would cover the principles and history of law, politics and morality. This is illustrated by his analysis of the paradox of commercial society and his demonstration of how wealth led to the restoration of liberty and the establishment of regular governance. Marx and the German historical school both strove to identify laws of the historical development of society, although they each rejected the other elements of the other's concept. Schumpeter's oeuvre was marked by an effort to combine theoretical analysis with historical description, so that from an analysis of economic development he could arrive at a theory presenting the interdependence of the various areas of social activity.

This dissertation is about commercial agriculture in nineteenth-century Liberia. Based primarily on the archives of the American Colonization Society (founder of Liberia), it examines the impact of environmental and demographic constraints on an agrarian settler society from 1822 to the 1890s. Contrary to the standard interpretation, which linked the poor state of commercial agriculture to the settlers' disdain for cultivation, this dissertation argues that the scarcity of labor and capital impeded the growth of commercial agriculture. The causes of the scarcity were high mortality, low immigration and the poverty of the American “Negroes” who began to settle Liberia in 1822. ^ Emigration to Liberia meant almost certain death and affliction for many immigrants because they encountered a new set of diseases. Mortality was particularly high during the early decades of colonization. From 1822 to 1843, about 48 percent of all immigrants died of various causes, usually within their first year. The bulk of the deaths is attributed to malaria. There was no natural increase in the population for this early period and because American “Negroes” were unenthusiastic about relocation to Liberia, immigration remained sparse throughout the century. Low immigration, combined with the high death rate, deprived the fledgling colony of its potential human resource, especially for the cultivation of labor-intensive crops, like sugar cane and coffee. Moreover, even though females constituted approximately half of the settlers, they seldom performed agricultural labor. ^ The problem of labor was compounded by the scarcity of draft animals. Liberia is in the region where trypanosomiasis occurs. The disease is fatal to large livestock. Therefore, animal-drawn plows, common in the United States, were never successfully transplanted in Liberia. Besides, the dearth of livestock obstructed the development of the sugar industry since many planters depended on oxen-powered mills because they could not afford to buy the more expensive steam engine mills. ^ Finally, nearly half of the immigrants were newly emancipated slaves. Usually these former bondsmen arrived in Liberia penniless. Consequently, they lacked the capital to invest in large-scale plantations. The other categories of immigrants (e.g., those who purchased their freedom), were hardly better off than the emancipated slaves. ^

This paper introduces the concept of an environmental history of Australia at war, and explores the various avenues that might be investigated within this emerging, multidisciplinary theme. Specifically, this paper focuses on the environmental histories of militarised landscapes on the Australian homefront, including in particular the land and sea military training areas that form part of the Department of Defence’s three-million hectare estate, and examines how cycles of war and peace have affected these environments.

The ratite moa (Aves: Dinornithiformes) were a speciose group of massive graviportal avian herbivores that dominated the New Zealand (NZ) ecosystem until their extinction �600 years ago. The phylogeny and evolutionary history of this morphologically diverse order has remained controversial since their initial description in 1839. We synthesize mitochondrial phylogenetic information from 263 subfossil moa specimens from across NZ with morphological, ecological, and new geological data to create the first comprehensive phylogeny, taxonomy, and evolutionary timeframe for all of the species of an extinct order. We also present an important new geological/paleogeographical model of late Cenozoic NZ, which suggests that terrestrial biota on the North and South Island landmasses were isolated for most of the past 20–30 Ma. The data reveal that the patterns of genetic diversity within and between differentmoaclades reflect a complex history following a major marine transgression in the Oligocene, affected by marine barriers, tectonic activity, and glacial cycles. Surprisingly, the remarkable morphological radiation of moa appears to have occurred much more recently than previous early Miocene (ca. 15 Ma) estimates, and was coincident with the accelerated uplift of the Southern Alps just ca. 5–8.5 Ma. Together with recent fossil evidence, these data suggest that the recent evolutionary history of nearly all of the iconic NZ terrestrial biota occurred principally on just the South Island.

Cockatoos are the distinctive family Cacatuidae, a major lineage of the order of parrots (Psittaciformes) and distributed throughout the Australasian region of the world. However, the evolutionary history of cockatoos is not well understood. We investigated the phylogeny of cockatoos based on three mitochondrial and three nuclear DNA genes obtained from 16 of 21 species of Cacatuidae. In addition, five novel mitochondrial genomes were used to estimate time of divergence and our estimates indicate Cacatuidae diverged from Psittacidae approximately 40.7 million years ago (95% CI 51.6–30.3 Ma) during the Eocene. Our data shows Cacatuidae began to diversify approximately 27.9 Ma (95% CI 38.1–18.3 Ma) during the Oligocene. The early to middle Miocene (20–10 Ma) was a significant period in the evolution of modern Australian environments and vegetation, in which a transformation from mainly mesic to xeric habitats (e.g., fire-adapted sclerophyll vegetation and grasslands) occurred. We hypothesize that this environmental transformation was a driving force behind the diversification of cockatoos. A detailed multi-locus molecular phylogeny enabled us to resolve the phylogenetic placements of the Palm Cockatoo (Probosciger aterrimus), Galah (Eolophus roseicapillus), Gang-gang Cockatoo (Callocephalon fimbriatum) and Cockatiel (Nymphicus hollandicus), which have historically been difficult to place within Cacatuidae. When the molecular evidence is analysed in concert with morphology, it is clear that many of the cockatoo species’ diagnostic phenotypic traits such as plumage colour, body size, wing shape and bill morphology have evolved in parallel or convergently across lineages.

Recent literature has argued that environmental efficiency (EE), which is built on the materials balance (MB) principle, is more suitable than other EE measures in situations where the law of mass conversation regulates production processes. In addition, the MB-based EE method is particularly useful in analysing possible trade-offs between cost and environmental performance. Identifying determinants of MB-based EE can provide useful information to decision makers but there are very few empirical investigations into this issue. This article proposes the use of data envelopment analysis and stochastic frontier analysis techniques to analyse variation in MB-based EE. Specifically, the article develops a stochastic nutrient frontier and nutrient inefficiency model to analyse determinants of MB-based EE. The empirical study applies both techniques to investigate MB-based EE of 96 rice farms in South Korea. The size of land, fertiliser consumption intensity, cost allocative efficiency, and the share of owned land out of total land are found to be correlated with MB-based EE. The results confirm the presence of a trade-off between MB-based EE and cost allocative efficiency and this finding, favouring policy interventions to help farms simultaneously achieve cost efficiency and MP-based EE.

Currently there is a paucity of records of late Quaternary palaeoenvironmental variability available from the subtropics of Australia. The three continuous palaeoecological records presented here, from North Stradbroke Island, subtropical Queensland, assist in bridging this large spatial gap in the current state of knowledge. The dominance of arboreal taxa in the pollen records throughout the past >40,000 years is in contrast with the majority of records from temperate Australia, and indicates a positive moisture balance for North Stradbroke Island. The charcoal records show considerable inter-site variability indicating the importance of local-scale events on individual records, and highlighting the caution that needs to be applied when interpreting a single site as a regional record. The variability in the burning regimes is interpreted as being influenced by both climatic and human factors. Despite this inter-site variability, broad environmental trends are identifiable, with changes in the three records comparable with the OZ-INTIMATE climate synthesis for the last 35,000 years.

The collection of basic environmental data by industry members was successful and offers a way of overcoming the problems associated with differences in scale between the environment and fisheries datasets. A simple method of collecting environmental data was developed that was only a small time burden on skippers, yet has the potential to provide very useful information on the same scale as the catch and effort data recorded in the logbooks. The success of this trial was aided by the natural interest of fishers to learn more about the environment in which they fish. The archival temperature-depth tags chosen proved robust, reliable and easy to use. While the use of large scale environmental data may not yield significant improvements in stock assessments for most SESSF species, fine-scale data collected from selected vessels using methods developed during this project may, in the longer term, be useful for incorporation into CPUE standardisations in the future...

Termites have colonized many habitats and are among the most abundant animals in tropical ecosystems, which they modify considerably through their actions. The timing of their rise in abundance and of the dispersal events that gave rise to modern termite lineages is not well understood. To shed light on termite origins and diversification, we sequenced the mitochondrial genome of 48 termite species and combined them with 18 previously sequenced termite mitochondrial genomes for phylogenetic and molecular clock analyses using multiple fossil calibrations. The 66 genomes represent most major clades of termites. Unlike previous phylogenetic studies based on fewer molecular data, our phylogenetic tree is fully resolved for the lower termites. The phylogenetic positions of Macrotermitinae and Apicotermitinae are also resolved as the basal groups in the higher termites, but in the crown termitid groups, including Termitinae + Syntermitinae + Nasutitermitinae + Cubitermitinae, the position of some nodes remains uncertain. Our molecular clock tree indicates that the lineages leading to termites and Cryptocercus roaches diverged 170 Ma (153-196 Ma 95% confidence interval [CI]), that modern Termitidae arose 54 Ma (46-66 Ma 95% CI), and that the crown termitid group arose 40 Ma (35-49 Ma 95% CI). This indicates that the distribution of basal termite clades was influenced by the final stages of the breakup of Pangaea. Our inference of ancestral geographic ranges shows that the Termitidae, which includes more than 75% of extant termite species, most likely originated in Africa or Asia, and acquired their pantropical distribution after a series of dispersal and subsequent diversification events.
