Status-Seeking, Catching-Up, and Comparative Statics in a Dynamic Heckscher-Ohlin Model

This paper examines a two-country dynamic general equilibrium model with status-seeking agents. We show that the introduction of status-seeking behavior brings about new properties in equilibrium dynamics. While there exists a continuum of steady states in the standard dynamic models, the present framework demonstrates that, under some conditions, there uniquely exists an incompletely specialized steady state, which is locally saddle-point stable. Therefore, catching-up and overtaking phenomena seen in economic development can be explained, and comparative statics analysis also is made possible. Our comparative statics analysis illustrates, for example, that trade pattern is determined in the Heckscher-Ohlin manner; the patient country acts just like a capital abundant one to export the capital-intensive good. Furthermore, as distinct from the existing literature, the present study shows that the existence of an incompletely specialized steady state can be ensured even if the two countries conduct different policies.

Inhibition of HSP 90 by triptolide ( TPL ) augments Bortezomib-induced U 266 cells apoptosis

HSP90 has high expression in myeloma cells and very important for prognosis, and that triptolide (TPL), the main active component of the traditional chinese herbal medicine Tripterygium wilfordii Hook F (Celastraceae) has the inhibition effects in the growth of myeloma cells. In this study, we test the ability of TPL to induce apoptosis in U266 human myeloma cells by reducing HSP90 expression, as well as the effect of TPL on Bortezomib sensitivity. The MTT cell viability assay was used to assess growth inhibition of U266 human myeloma cells due to different TPL concentrations and the combined use of different concentration of TPL and 0.01 mM Bortezomib. Annexin-V and Propidium iodide (PI) labeling were used to detect cell death and determine the mode of death. TPL alone inhibited U266 cell growth and apoptosis inducement in a concentration-dependent manner. When TPL is combined with 0.01 mM Bortezomib, both effects increase. Western blotting revealed that caspase 3 and caspase 9 gene expression increased, while nuclear factor (NF)-KB and HSP 90 protein expression decreased, related with apoptosis and growth inhibition. TPL increases U266 cell sensitivity to Bortezomib, inducing apoptosis, which might be the result of suppress NF-KB and HSP90 activity.
Spatial patterns of precipitation anomalies in eastern China during centennial cold and warm periods of the past 2000 years

The spatial patterns of precipitation anomalies in eastern China during both warm and cold periods over the past 2000 years were studied. Four warm periods (AD 650–750, AD 1000–1100, AD 1190–1290, and AD 1900–2000) and five cold periods (AD 440–540, AD 780–920, AD 1390–1460, AD 1600–1700, and AD 1800–1900) were selected on a centennial timescale, referring to the synthesized temperature changes over China and Northern Hemisphere. The regional differences in precipitation were analysed and compared using a data set consisting of the grades in severity of floods and droughts as derived from Chinese historical documents. The results showed that there has been no fixed spatial pattern of precipitation anomalies during either cold or warm periods in eastern China over the past 2000 years. For the most of warm periods, there existed coherence of spatial pattern with dry condition only occurred over north of the Yangtze River, and the consistent spatial patterns were found between the periods 650–750 and 1190–1290, 650–750, and 1000–1100. For the cold periods, the precipitation showed various spatial patterns, and similarities were only presented in the two periods of 1600–1700 and 1800–1900 featured by meridional distribution. Comparing the spatial patterns between cold and warm periods, inverse pattern of 440–540 and 1900–2000 over the most study area can be detected, but similar pattern was also found between the periods 1800–1900 and 1900–2000, and 1600–1700 and 1900–2000. Our results implicated that the relationship between temperature and spatial pattern of precipitation anomaly has high complexity, which would be of significance to understanding the spatial pattern of precipitation in the future climate change study.
Study of heat transfer on front- and back-vented brake discs

A brake disc plays an important role in the automotive industry since it concerns directly with safety. In order to develop proper heat ventilation a wide range of brake discs have been designed. Different types of physical brake disc geometries, as front- and back-vented brake discs, affect the heat ventilation directly. This is a vital factor of the brake’s capability. We recognized the importance of this circumstance and therefore attempted to create a test to investigate the temperature gradient of the brake disc in order to evaluate the coefficients of heat convection. The coefficients were modified by the change of temperature distribution in both brake discs under the forced heat convection in steady state conditions. However, the heat radiation value does not take into account that the heat convection is dominated by the physical geometry of the brake disc. To set up the experimental test for investigating the heat transfer by convection the JASO C406 standard is adopted. The experimental results in terms of heat convection coefficients are used in the numerical simulation via the finite element method in order to study the temperature diffusion and heat ventilation of front and back-vented brake discs. Consequently, the experimental results reveal that the overall heat convection coefficients of the front-vented brake disc are higher than these of the back-vented one. In other words the simulation yields that the front-vented brake disc allows stronger heat ventilation than its compared object, leading to larger temperature differences between outboard and inboard rotors, resulting in more thermal stress. This makes it more susceptible to be damaged during operation.
Schrödinger operator with magnetic field in domain with corners

We present here a simplified version of results obtained with F. Alouges, M. Dauge, B. Helffer and G. Vial (cf [4, 7, 9]). We analyze the Schrodinger operator with magnetic field in an infinite sector. This study allows to determine accurate approximation of the low-lying eigenpairs of the Schrodinger operator in domains with corners. We complete this analysis with numerical experiments. Acknowledgements I wish to thank F. Alouges, M. Dauge, B. Helffer and G. Vial for numerous discussions about this subject and also for their collaboration in part of this work.
Gezichtsbedrog onthult hersenwerking in drie-dimensionale waarneming

Gezichtsbedrog biedt een venster op de werking van de hersenen omdat het onderliggende waarnemings-mechanismen kan onthullen op een manier die niet mogelijk is tijdens waarheidsgetrouwe waarneming. Hier wordt getoond hoe een klassiek voorbeeld van gezichtsbedrog inspiratie geeft voor de ontwikkeling van een hersenmodel voor drie- dimensionale waarneming. Zulke modellen kunnen tal van praktische toepassingen vinden in de geneeskunde, luchtvaart en robotiek.
INDUSTRY MOMENTUM IN AN EARLIER TIME: EVIDENCE FROM THE COWLES DATA

type="main" xml:lang="en"> Virtually all evidence on the efficacy of momentum strategies arises from the post-1962 era, and momentum returns across different markets and asset classes are highly positively correlated. We examine industry momentum in an earlier time and find that these strategies would have earned gross returns over the 1900–1925 period that are at least equal to those in the modern era; however, there is little evidence of profitability before 1900. The paucity of industry coverage in the earlier years of the Cowles database likely does not explain this differential profitability. We also show that the market state dependence of momentum strategies in the 1900–1925 period is similar to the modern era.
Vocal repertoire of Scinax v-signatus (Lutz 1968) (Anura, Hylidae) and comments on bioacoustical synapomorphies for Scinax perpusillus species group

Herein we describe the vocal repertoire of Scinax v - signatus , compare it to the other species belonging to the S . perpusillus species group and discuss the bioacoustical synapomorphies proposed for the group. We recorded an advertisement call and an aggressive call of S . v - signatus . The advertisement call is similar to the one described for others species of the Scinax perpusillus group. Similarly to Scinax cosenzai , the first note in the advertisement call of S . v - signatus is the longest. The aggressive call was preceded by a series of advertisement calls. We suggest that bioacoustical parameters proposed as synapomorphies for the Scinax perpusillus group are not valid, as they are also observed in species belonging to other groups within the genus.
An Analysis of Subjective Views of Job Insecurity

In the 1997 and 1998 waves of the British Household Panel Survey, workers are asked to assess their level of job security in terms of the probability of becoming unemployed within the next year. We examine whether these perceptions of insecurity are purely subjective or are systematically related to certain characteristics of the worker and their current job. The responses offered by workers suggest that around 10% are in fear of becoming unemployed, and this fear is not persistently confined to the same workers or to particular occupational groups. Individuals with a history of unemployment and those holding short-term employment contracts are found to report the greatest levels of insecurity. Finally, we find that workers' perceptions of unemployment are strong predictors of actual unemployment experiences occurring in the subsequent year. We therefore conclude that such subjective measures of insecurity do convey useful information that may be used in further analyses of the workings of the labour market.
Metal nanoparticles and their assemblies

Metal nanoparticles of varying sizes can be prepared by physical as well as chemical methods. They exhibit many fascinating properties, the size-dependent metal to nonmetal transition being an important one. Metal nanoparticles capped by thiols can be organized into ordered one-, two- and three-dimensional structures and these structures have potential applications in nanodevices. In this context, organization of arrays of metal nanoparticles with a fixed number of atoms assumes significance.
Routine outcome monitoring in psychiatric clinical practice: background, overview and implications for person-centered psychiatry

Routine Outcome Monitoring (ROM) is the systematic measurement of treatment outcomes in routine clinical practice. On the level of the patient and clinician, ROM may be a valuable source of information about patient’s symptoms, treatment progress and psychosocial functioning. Furthermore, ROM can be used for purposes of research and benchmarking. The naturalistic character of the evaluations provide data that are more representative of ‘real-world’ patients than data derived from clinical trials. Despite these advantages, ROM has not been extensively implemented in psychiatry. The aim of the present qualitative review was to provide an overview of the conceptual background of the historical development, aims, methodological issues and potential applications of ROM in psychiatric outpatient settings and to consider their relevance to the development of person-centered psychiatry.
Application of CMOS-MEMS integrated resonators to RF communication systems

Els dispositius MEMS han demostrat la seva utilitat en un gran ventall d'aplicacions de sensat i actuacio. L'extensio al domini de RF d'aquests elements mecanics son ara una de les peces clau per sistemes altament reconfigurables referencies de frequencia i processadors de senyals. Aquesta tesi es centra en algunes de les aplicacions dels dispositius MEMS en el domini de RF: referencies de frequencia per oscil·ladors, filtres i mescladors. Els resonadors que es presenten en aquesta tesi s'han fabricat completament en tecnologies CMOS comercials per aprofitar la integracio de MEMS i circuiteria complementaria i el baix cost de fabricacio d'aquestes tecnologies. Diferents tipus de ressonadors MEMS s'han dissenyat i fabricat a fi d'avaluar les seves prestacions en diferents propietats. La validesa de la tecnica emprada per fabricar els MEMS en tecnologies CMOS futures s'ha demostrat fabricant i testant amb exit resonadors MEMS en dos tecnologies diferents: de diferents fabriques i nodes tecnologics (0.35um i 0.18um). La frequencia de ressonancia d'aquests dispositius mecanics es troben a les bandes de HF i VHF. Tots aquests dispositius basats en bigues flexurals, presenten un major factor de qualitat Q que els tancs LC integrats i son a mes a mes sintonizables en frequencia, amb una mida inferior a la dels citats tancs LC. Els ressonadors MEMS-CMOS descrita a la tesi presenten un valor de Qxf en el rang entre 1GHz i els 10GHz mesurats a l'aire. Aquests valors es milloren mesurant al buit arribant als 100GHz, majors a qualsevol altre ressonador basat en tecnologia CMOS. Les aplicacions de mesclat i filtrat de senyals tambe s'estudien. Dins d'aquestes aplicacions, la meta es definir una banda passant plana combinant diferents ressonadors. El prototipus d'un filtre paral·lel basat en ponts i un amplificador diferencial CMOS monolitic presenta una banda passant plana de 200kHz a una frequencia central de 21.66MHz quan es mesura a l'aire. Tambe es demostra el filtrat emprant un unic ressonador del tipus tuning fork. Com a mesclador, es destacable la possibilitat de convertir a alta i baixa senyals de 1GHz amb un ressonador de 22MHz Com a oscil·ladors monolitics, es mostra un oscil·lador operatiu per tensions DC baixes ( 5V), gracies a la reduccio del gap del ressonador. L'oscil·lador basat en un tuning fork aconsegueix valors de soroll de fase de -87dBc/Hz@10kHz i -98.7dBc/Hz@100kHz, millor que altres oscil·ladors CMOS monolitic reportats.
Physiological response to drought and Dehydration responsive transcripts(DRTs) from the leaves of water-deficit Indian soybean [Glycine max (L.)Merrill cv NRC7]

Drought is a major reason for reduced productivity in principal food crops including soybean. Development of drought tolerant varieties is imperative to tide over erratic rainfall conditions in Indian context. Here we studied molecular mechanism governing drought tolerance in Indian soybean cultivar NRC7 to identify drought responsive genic biomarkers. Drought associated physiological parameters like relative water content (RWC) and electrolytic leakage studies under water-deficit condition revealed very low water status in the stressed plants. In addition, membrane damage studies on electrolytic leakages revealed that the stressed plants exhibited greater membrane damage than control plants. Differential display RT-PCR (DD-RT-PCR) identified two drought responsive transcripts (gmDRT1 and gmDRT2) from the soybean cultivar NRC7. The identified transcripts were found to have sequence homology with dehydrin protein and ion ATPase transporters. These biomarkers identified for drought tolerance would also help in engineering drought tolerant soybean cultivars.
The NE subarctic Pacific in winter: I. Biological standing stocks

Although an extensive biological time series data set of phytoplankton and zooplankton standing stocks has been collected over a 30 yr period in the NE subarctic Pacific at Ocean Station Papa (OSP), the majority of these data were obtained before recent advances in our understanding of the structure and functioning of the manne microbial food web. In addition, recent studies did not obtain data during the winter penod. This paper provides the first contemporary biological description of the NE subarctic Pacific dunng winter Data from 2 winter cruises in the vicinity of OSP indicate that the abundance and composition of the autotrophic and heterotroph~c assemblage at these times are similar to those observed during late spring and summer by others. In contrast, winter mesozooplankton standing stocks are considerably less than observed In summer. These findings confirm the hypothesis that the relatively shallow winter mixed layer permits relatively high standing stocks of phytoplankton (20 mg C m-3) and consequently of microheterotrophs (7.1 to 13.1 mg C m-7 to subsist over the winter period. An assessment of autotrophic and heterotrophic biomass suggests that the requirements of the mesozooplankton (Stages IV to VI), microzooplankton and heterotrophic nanoflagellates may potentially be balanced by the standlng stocks of microplankton, nanoplankton/picophytoplankton, and picoplankton, respectively. However, the carbon requirements of heterotrophic bacteria cannot be balanced without invoking slower turnover times for thls pool relative to the turnover times for the dissolved organic carbon (DOC) pool.
A Microblog User Interest Model Based on Participated and Not Participated Data

Oriented to the social network and media such as micro-blog, this paper presents a constructing way of user interest model. Based on the date whether user participated or not, user interest was divided into participated part and not-participated part. Instead of gaining friends’ interests and then considering the immediate effect towards user’s interest, the influence of friends’ interests take effects through the long-term friends-generated user-participated data explicitly and the short-term friends-generated user-not participated data implicitly. Forgetting mechanism helped modelling the user interest drift. Simulated experiments verify the proposed user interest modelling method is effective and the not participated data plays a more important role than the participated data.
The Short- and Long-Term Effects of Graduating During a Recession: Evidence from Finland

This paper uses matched employer-employee panel data on university graduates who obtained a Master’s degree in 1988–2004 to study how facing adverse economic conditions upon graduation affects shortand long-term labor market outcomes in Finland. Among all graduation cohorts, the average graduate faces large and persistent negative effects on real annual earnings that last for at least the first ten years after graduation. There is also a persistently higher probability of being unemployed that lasts for roughly seven years. When only considering the cohorts who graduated after the exceptionally deep Finnish 1990s depression, the effects on earnings only last for the first five years and there appear to be little to no effects on unemployment. Female graduates face smaller earnings losses on average, potentially reflecting gender differences in fields of study, employing sector and labor market attachment. The empirical results appear not to be significantly affected by selective timing or place of graduation.
Perceptions of behaviours in stranger rape cases: a sequence analysis approach

ABSTRACT Psychological research into perceptions of sexual attacks, rape myths, and scripts usually involves questionnaires or qualitative reports. A new method for investigating the perceived dynamic sequence of behaviours between victim and attacker could help to outline common perceptions. The current study uses a Behaviour Sequence Analysis approach to investigate females’ perceptions of the interaction between a female victim and unknown, male attacker. A sample of females was asked to report their perceptions of the interaction between a female and stranger at night, leading up to a rape attack. The results indicated that females did not perceive weapons or excessive force to be likely behaviours. Also, females responded that most attackers would begin by first attempting to engage a female in conversation. An important contribution of the current research is to show temporal associations between behaviours. In addition, the current research highlights the strength of sequence analysis for understanding perceptions of dynamic patterns of violent behaviours.
CHITOSAN COATED SURFACE MODIFIED POLYPROPYLENE FABRIC FOR THE REMOVAL OF CD(II) AND ZN(II)IONS FROM AQUEOUS SOLUTION

Chitosan coated on a polypropylene fabric enhances the mechanical stability and reduces gel forming behavior of chitosan. Chitosan coated on H2SO4 treated polypropylene fabric and cross linked with glutaraldehyde was used for the preparation of filter. The quantity of the chitosan coated PP fabric was studied using thermo gravimetric analyzer. The Adsorption studies of Cd(II), Zn (II) ions was carried out in a batch process at room temperature in static manner with varying all possible parameters such as pH of solution, adsorbent concentration, metal concentration etc. Metal concentration was measured using ICP AES. It has been shown that CS coated PP fabric is an excellent adsorbent for heavy metals and a filtering unit may be fabricated using this technology at lower expenses.
THE ROLE OF EPOXIDATION ON CAMELINA Sativa BIODIESEL PROPERTIES

An unstandarised biodiesel made from Camelina sativa oil, having over a 90 percent by weight of unsaturated fatty acids, were transformed into an epoxidised biodiesel that satisfy the requirements for iodine value, linolenic acid methyl ester content, cetane number, polyunsaturated fatty acids content, and viscosity established by the EN 14214 and ASTM D 6751 standards. The epoxidation reaction was carried out at 60 °C using peroxyacetic acid generated in situ and sulphuric acid as catalyst. A conversion of 60 % of double bonds was reached after 3 hours of reaction. However, only one hour was needed to get standard requirements and to avoid the epoxide ring opening side reaction that leads to hydroxyl groups. Besides, it was also observed that the formation of hydroxyl groups increases the kinematic viscosity of the biodiesel, being deleterious for the biodiesel properties.
Plant defence inducer properties of the grape marc extract

Plant defence inducers (PDIs) constitute a class of bioactive compounds with an emerging potential to be integrated in plant protection strategies. Plant extracts such as grape marc extract (GME) could elicit plant defence responses in different species. Foliar infiltration of GME to tomato and Arabidopsis leaves resulted in the appearance of macroscopic symptoms and autofluorescent compounds.
Modeling Tree Diameter Distributions in Natural Forests: An Evaluation of 10 Statistical Models

In forestry, the description of tree sizes is commonly performed by fitting statistical models to diameter distributions. However, there is little agreement on which models are more flexible to this end, especially in tropical forests. Here we provide the simultaneous evaluation at species and subplot levels of 10 models using large data sets from four representative forest types in Brazil. We aimed to detect which models provide best fits and under which sample properties (size, median, variance, skewness, and kurtosis). We show that the combination of the logit-logistic, odd Weibull, Weibull, and Johnson’s special bounded models provided reasonable descriptions for nearly all species (94.8%) and subplots (99.6%). However, there was little overlap between these four models, meaning that single models were rarely appropriate to describe the majority of cases. This complementarity was evident between the odd Weibull (better performance for more symmetrical, bimodal, or rotated-sigmoid patterns) and logit-logistic models (typical right-skewed and heavy-tailed patterns). The performance of all models was significantly related to forest type or sample properties. Models with more than three parameters had more problems related to optimization convergence, confidence interval estimation, and unrealistic fits. Finally, we discuss some theoretical issues related to the choice of appropriate models.
