THE SEARCH FOR A MODEL OF PUBLIC ADMINISTRATION REFORM IN HONG KONG: WEBERIAN BUREAUCRACY, New PUBLIC MANAGEMENT OR SOMETHING ELSE?
Authors: Wong Wilson 
Published: September 2013

SUMMARYThis article examines the limits of Western public administration models and the importance of a contextually embedded and empirically based approach of knowledge building in Asian public administration. It is attainted through a case study of the post‐1997 public administration reform in Hong Kong to illustrate the mismatching between major models of Western public administration and the Asian domestic contexts. There are questions and doubts about both the goals and results of the public management reforms in Hong Kong. This article argues that post‐handover reforms in Hong Kong cannot be fully explained by the normative and efficiency‐oriented model of new public management self‐claimed by the government. They are driven more by the political elite that emerged in the new political order after Hong Kong's transfer of sovereignty in 1997. Using administrative solutions to resolve political problems and address concerns on the domestic agenda has been a character of Hong Kong's administration, which is generalizable to other Asian countries. The article also sheds light on the bigger underlying questions raised in comparative public administration about the inadequate explanatory power of generalized Western public administration models and how the national context of Asian countries is more diverse and complicated from a so‐called global model.

AbstractIn Mediterranean ecosystems, the European rabbit is a keystone species that has declined dramatically, with profound implications for conservation and management. Predation and disease acting on juveniles are considered the likely causes. In the field, these processes are managed by removing predators, increasing cover to reduce predation risk and by vaccinating against myxomatosis. These manipulations can be costly and, when protected predators are killed, they can also be damaging to conservation interests. Our goal was to test the effectiveness of cover and vaccination on juvenile survival in two large enclosures, free of mammalian predators, by adding cover and vaccinating juveniles. Rabbit warrens were our experimental unit, with nine replicates of four treatments: control, cover, vaccination, and cover and vaccination combined. Our results showed that improved cover systematically increased juvenile rabbit survival, whereas vaccination had no clear effect and the interactive effect was negligible. Our experimental data suggest that improved cover around warrens is an effective way of increasing rabbit abundance in Mediterranean ecosystems, at least when generalist mammalian predators are scarce. In contrast the vaccination programme was of limited benefit, raising questions about its efficacy as a management tool.
Stage‐ and weather‐dependent dispersal in the brown garden snailCornu aspersum

Published: September 2013

AbstractDispersal decisions are often condition‐dependent, influenced by the interaction of individual phenotype and environmental conditions. Terrestrial Gastropods are simultaneous hermaphrodites, a reproductive system rarely studied in the context of dispersal. Moreover, the energetic cost of their movement is one of the highest among animals. Despite these features, which make them valuable models to understand the trade‐offs between dispersal and other life‐history traits, their dispersal strategies have been barely explored. We studied the movements of subadults and adults of the brown garden snailCornu aspersumin a semi‐natural 4‐patch network, for 2 months in 2011 (a dry year) and 1 month in 2012 (a wet year). We assessed the effects of life‐history stage (subadult/adult) and weather conditions on dispersal propensity and dispersal speed. Snails were more mobile under humid and warm weather, but nearly all individuals left patches when the relative humidity was close to 100 % in 2012. Because such humidity levels are potentially lethal toC. aspersum, we argue these extreme emigration rates might be an emergency escape response to harmful conditions. Despite a theoretically higher cost of movement, we found that subadults emigrated more, and dispersed faster and further, than adults. Thus, and contrary to what was expected, direct costs of movement do not play the main role in shaping dispersal inC. aspersum. Observed differences between subadults and adults in dispersal behaviour are discussed in the context of intraspecific competition, inbreeding avoidance and relative costs of male and female reproduction.
From High Accuracy to High Efficiency in Simulations of Processing of Dual-Phase Steels

Abstract
Searching for a compromise between computing costs and predictive capabilities of metal processing models is the objective of this work. The justification of using multiscale and simplified models in simulations of manufacturing of DP steel products is discussed. Multiscale techniques are described and their applications to modeling annealing and stamping are shown. This approach is costly and should be used in specific applications only. Models based on the JMAK equation are an alternative. Physical simulations of the continuous annealing were conducted for validation of the models. An analysis of the computing time and predictive capabilities of the models allowed to conclude that the modified JMAK equation gives good results as far as prediction of volume fractions after annealing is needed. Contrary, a multiscale model is needed to analyze the distributions of strains in the ferritic-martensitic microstructure. The idea of simplification of multiscale models is presented, as well.
On the strength of the nonlinearity in isotropic turbulence
Authors: Bos W. J. T. , Rubinstein R. 
Published: September 2013

AbstractTurbulence governed by the Navier–Stokes equations shows a tendency to evolve towards a state in which the nonlinearity is diminished. In fully developed turbulence, this tendency can be measured by comparing the variance of the nonlinear term to the variance of the same quantity measured in a Gaussian field with the same energy distribution. In order to study this phenomenon at high Reynolds numbers, a version of the direct interaction approximation is used to obtain a closed expression for the statistical average of the mean-square nonlinearity. The wavenumber spectrum of the mean-square nonlinear term is evaluated and its scaling in the inertial range is investigated as a function of the Reynolds number. Its scaling is dominated by the sweeping by the energetic scales, but this sweeping is weaker than predicted by a random sweeping estimate. At inertial range scales, the depletion of nonlinearity as a function of the wavenumber is observed to be constant. At large scales it is observed that the mean-square nonlinearity is larger than its Gaussian estimate, which is shown to be related to the non-Gaussianity of the Reynolds-stress fluctuations at these scales.
Evaluations of Actiheart, IDEEA® and RT3 monitors for estimating activity energy expenditure in free-living women
Authors: Löf Marie , Henriksson Hanna , Forsum Elisabet 
Published: September 2013

AbstractActivity energy expenditure (AEE) during free-living conditions can be assessed using devices based on different principles. To make proper comparisons of different devices' capacities to assess AEE, they should be evaluated in the same population. Thus, in the present study we evaluated, in the same group of subjects, the ability of three devices to assess AEE in groups and individuals during free-living conditions. In twenty women, AEE was assessed using RT3 (three-axial accelerometry) (AEERT3), Actiheart (a combination of heart rate and accelerometry) (AEEActi) and IDEEA (a multi-accelerometer system) (AEEIDEEA). Reference AEE (AEEref) was assessed using the doubly labelled water method and indirect calorimetry. Average AEEActi was 5760 kJ per 24 h and not significantly different from AEEref (5020 kJ per 24 h). On average, AEERT3 and AEEIDEEA were 2010 and 1750 kJ per 24 h lower than AEEref, respectively (P < 0·001). The limits of agreement (± 2 sd) were 2940 (Actiheart), 1820 (RT3) and 2650 (IDEEA) kJ per 24 h. The variance for AEERT3 was lower than for AEEActi (P = 0·006). The RT3 classified 60 % of the women in the correct activity category while the corresponding value for IDEEA and Actiheart was 30 %. In conclusion, the Actiheart may be useful for groups and the RT3 for individuals while the IDEEA requires further development. The results are likely to be relevant for a large proportion of Western women of reproductive age and demonstrate that the procedure selected to assess physical activity can greatly influence the possibilities to uncover important aspects regarding interactions between physical activity, diet and health.

The inhibition of the attachment of bacteria to the intestine by receptor analogues could be a novel approach to prevent enterotoxigenicEscherichia coli(ETEC) K88-induced diarrhoea in piglets. The objective of the present study was to screen the ability of different feed ingredients (FI) to bind to ETEC K88 (adhesion test, AT) and to block its attachment to the porcine intestinal mucus (blocking test, BT) usingin vitromicrotitration-based models. In the AT, wheat bran (WB), casein glycomacropeptide (CGMP) and exopolysaccharides exhibited the highest adhesion to ETEC K88 (P< 0·001). In the BT, WB, CGMP and locust bean (LB) reduced the number of ETEC K88 attached to the intestinal mucus (P< 0·001). For WB and LB, fractionation based on their carbohydrate components was subsequently carried out, and each fraction was evaluated individually. None of the WB fractions reduced the adhesion of ETEC K88 to the mucus as did the original extract, suggesting that a protein or glycoprotein could be involved in the recognition process. With regard to the LB fractions, the water-extractable material reduced the adhesion of ETEC K88 (P< 0·001) to the mucus similar to the original extract (P< 0·001), indicating, in this case, that galactomannans or phenolic compounds could be responsible for the recognition process. In conclusion, among the FI screened, the soluble extracts obtained from WB, LB and CGMP exhibited the highest anti-adhesive properties against ETEC K88 in the BT. These results suggest that they may be good candidates to be included in diets of weaned piglets for the prevention of ETEC K88-induced diarrhoea.
A “Brutology” of Bozal: Tracing a Discourse Genealogy from Nineteenth-Century Blackface Theater to Twenty-First-Century Spirit Possession in Cuba
Authors: Wirtz Kristina 
Published: September 2013

AbstractIn tracing a discourse history for the emergence and enregisterment of Bozal, a Cuban speech style that robustly indexes the historical persona of the African slave, this paper proposes that such discourse “genealogies” are more accurately reconstructed not through a linear, teleological metaphor of “speech chains” but through a more reticulated, multiply stranded web of interdiscursive connections. Bozal, in contemporary Cuba, characterizes the voices of African deities and spirits of the dead who possess their devotees to speak during folk religious ceremonies. I consider a deeper history of theatrical “blackface” influences on religious performances of spirit possession, a discourse history that destabilizes facile notions of “authentic, African” cultural sources in Cuba. I argue that rather than reflecting direct memories ofactualspeech by African-born slaves, once upon a time, Bozal's enregisterment began with, and always involved, double-voiced representations of imagined social types—what recent scholarship has described as “mock” forms disparaging the speech of racialized Others. The “Bozal slave” was a figure caricatured for comedic effect, proliferating into a whole set of stock theatrical characters, some of which became focal points for building nationalist sentiment in mid-nineteenth-century Cuba. The lesson for understanding the role of Bozal or any “Africanizing” voice in performance today is clear: we must always consider the mediating effects of metacultural practices in shaping our understanding of the social meaning of speech styles.
“Population Politics” at the End of Empire: Migration and Sovereignty in Ottoman Eastern Rumelia, 1877–1886
Authors: Mirkova Anna M. 
Published: September 2013

AbstractThis article explores the migrations of Turkish Muslims after the 1878 Peace Treaty of Berlin, which severed much of the Balkans from the Ottoman Empire as fully independent nation-states or as nominally dependent polities in the borderlands of the empire. I focus on one such polity—the administratively autonomous Ottoman province of Eastern Rumelia—which, in wrestling to reconcile liberal principles of equality and political representation understood in ethno-religious terms, prompted emigration of Turkish Muslims while enabling Bulgarian Christian hegemony. Scholars have studied Muslim emigration from the Balkans as the Ottoman Empire gradually lost hold of the region, emphasizing deleterious effects of nationalism and aggressive state-building in the region. Here I look at migration at empire's end, and more specifically at the management of migration as constitutive of sovereignty. The Ottoman government asserted its suzerainty by claiming to protect the rights of Eastern Rumelia's Muslims. The Bulgarian dominated administration of Eastern Rumelia claimed not only administrative but also political autonomy by trying to contain the grievances of Turkish Muslims as a domestic issue abused by ill-meaning outsiders, all the while insisting that the province protected the rights of all subjects. Ultimately, a “corporatist” model of subjecthood obtained in Eastern Rumelia, which fused the traditional religious categorization of Ottoman subjects with an ethnic one under the umbrella of representative government. The tension between group belonging and individual politicization that began unfolding in Eastern Rumelia became a major dilemma of the post-Ottoman world and other post-imperial societies after World War I.
Taphonomy of diploporite (Echinodermata) holdfasts from a Silurian hardground, southeastern Indiana, United States: palaeoecologic and stratigraphic significance
Authors: THOMKA JAMES R. , BRETT CARLTON E. 
Published: September 2013

AbstractA microbioherm-bearing hardground within the middle Silurian (Wenlock) Massie Formation near Napoleon, southeastern Indiana, United States is encrusted by the attachment structures of numerous pelmatozoan echinoderms. Among the most common of these holdfasts are multi-plated discoidal structures representing the thecal attachments of diploporite ‘cystoids’. This large population of holdfasts permits the first detailed taphonomic and palaeoecologic study of hardground diploporite attachments, allowing for increased morphological understanding of these rarely studied structures and facilitating identification of holdfasts in deposits where they might have been overlooked or misidentified. The biostratinomic sequence commences with detachment of thecae, followed by weathering of isolated discoidal holdfasts to bring out radiating canal structures and plate sutures, eventually leading to removal of the interior floor to expose the underlying substrate. Continued exposure can result in separation of component holdfast plates, though cementation to the substrate prevents scattering of plates. Diagenetic precipitation of pyrite occurred after burial; the large size of crystals suggests late diagenesis, perhaps seeded by early diagenetic pyrite crystallites produced by decay of ligamentary tissue. Extrinsic taphonomic factors include overgrowth of holdfasts by laminar stenolaemate bryozoans and other echinoderm attachment structures. Diploporite holdfasts are not bored and are absent on microbioherms. Taphonomic data indicate the time-averaged nature of this hardground and its diploporite assemblage and permit prediction of similar occurrences at major flooding surfaces.
Mixed grazing systems of sheep and cattle to improve liveweight gain: a quantitative review
Authors: d'ALEXIS S. , SAUVANT D. , BOVAL M. 
Published: September 2013

SUMMARYMixed grazing is an alternative pasture management which can be used to increase ruminant performance and reduce gastro-intestinal nematodes. A meta-analysis was performed on the results of previous studies from the literature to quantify the benefit of mixed grazing with sheep and cattle and identify determinants and enhancing factors. The analysis focused on papers reporting measurements of average daily weight gain (ADG) of sheep and cattle, carried out simultaneously in mixed grazing and in mono-grazing. The meta-analysis used 179 observations from 16 experiments published in nine carefully selected papers. The benefits of mixed grazing were appraised using the individual ADG of sheep (ADGisheep), cattle (ADGicattle) and the overall performances (ADG per hectare (ADGha), g/day/ha). A theoretical production value (ADGha-Theo) was calculated from the ADGha in mixed and mono-grazing at similar stocking rates (SRs)/ha. The ADGisheepwas greater in mixed treatments compared with control treatments (+14·5 g/day,P<0·001) and varied with physiological status and SR (P<0·001). The ADGicattlewas similar in mixed and mono-grazing. At a global level ADGha in mixed treatments (ADGha-Mtrt) was higher by 28·6% compared with sheep alone and by 25·1% compared with cattle alone; also, ADGha-Mtrt was 8% higher than ADGha-Theo. The ADGha varied with physiological status and decreased with the proportion of sheep in association (P<0·01). The contribution of ADGha in mixed grazing due to each species was lower compared with gains for each species reared alone (1438v.2423 g/day/ha for sheep and 1687v.2491 g/day/ha for cattle,P<0·001).

AbstractObjective:To examine the clinical features, age and gender distribution of patients, treatment methods, and outcomes of benign paroxysmal positional vertigo.Methods:This paper reports a review of 357 patients treated for this condition at a single institution over a duration of 5 years. Patients with posterior canal benign paroxysmal positional vertigo were divided into two groups: one group underwent the Epley manoeuvre and the other received medication. The lateral canal canalolithiasis patients were also divided into two groups: one underwent the Lempert manoeuvre and the other received medication. Lastly, the lateral canal cupulolithiasis patients were treated with medication and non-specific physical techniques.Results and conclusion:For patients with posterior canal benign paroxysmal positional vertigo, resolution time was significantly shorter in the Epley manoeuvre group than in the medication group. For the lateral canal canalolithiasis patients, resolution time was significantly shorter in the Lempert manoeuvre group than in the medication group. Resolution time was significantly longer in the lateral canal cupulolithiasis patients than in the other patients. The average age of patients increased with the number of recurrences, as did predominance in females. Average age and rate of sensorineural hearing loss were significantly higher in patients with intractable benign paroxysmal positional vertigo compared with those in the curable benign paroxysmal positional vertigo group.
Disruption, control and coping: responses of and to the person with dementia in hospital

Published: September 2013

ABSTRACTThis qualitative study aimed to gain insight into the experience of hospitalisation from the perspectives of the older person with dementia, their family care-giver and other patients sharing the ward (co-patients). Non-participant observation of care on 11 acute hospital wards was supplemented by 39 semi-structured interviews with 35 family care-givers and four co-patients following discharge. Constant comparative analysis produced the core problem facing all those involved: disruption from normal routine meaning that the experience of hospitalisation was disrupted by the presence and behaviour of the person with dementia. Disruption adversely affected the person with dementia, triggering constructive, disengaged, distressed and neutral behaviours. Using Kitwood's model of person-centred care, these behaviours were interpreted as attempts by the person with dementia at gaining a sense of control over the unfamiliar environment and experience. Family care-givers' lives and experiences both inside and outside the hospital were disrupted by the hospitalisation. They too attempted to gain a sense of control over the experience and to give a sense of control to the patient, co-patients and staff. Co-patients experienced disruption from sharing space with the person with dementia and were left feeling vulnerable and sometimes afraid. They too attempted to gain a sense of control over their situation and give some control by helping the person with dementia, the family care-giver and the staff.
Generation of beating wave by multi-coaxial relativistic backward wave oscillator
Authors: Teng Y. , Liang T.Z. , Sun J. 
Published: September 2013

AbstractMulti-coaxial relativistic backward wave oscillator that generates the beating wave of high power microwave pulse driven by a single accelerator and a single guiding magnet system is presented. Making use of the coaxial annular cathodes that can synchronously produce three annular beams at one shot, the average power of 5.88 GW consisting of two frequency components 9.0 and 9.7 GHz is obtained under the diode voltage and current 724 and 19.57 kA, corresponding to the conversion efficiency 41.5%. The conversion efficiency and the beating frequency are considerably stable with the diode voltage. The coaxial transmission supporter developed from our previous experimental research is employed to conductively connect the coaxial structure and to incoherently combine the microwave pulse of two frequencies with little reflection. It is found that the equipotential connection of the coaxial structure modifies the field distribution in the diode structure to facilitate the operation of the coaxial annular cathodes. The coaxial cathodes of different lengths are proved to be efficient at depressing the space charge effect in order to prevent the explosive emission of the inner cathode from being shielded by the outer annular beams.
