What Is Good and What is Bad with the Eurosystem’s Published Forecasts, and How Can They Be Improved?¤

Eurosystem …nally published its eagerly awaited in ‡ation forecast (as well as a forecast of GDP growth). It did so after having been provoked and prodded to do so, by the European Parlia-ment's Committee on Economic and Monetary A¤airs and a large number of external observers and commentators, since the announcement of the Eurosystem monetary-policy strategy in the fall of 1998. This Brie…ng Paper discusses what is good and bad with these forecasts and how they could be improved. The primary objective of Eurosystem monetary policy is to maintain price stability, de…ned as an annual increase in the HICP below two percent. 1 Because of the lags in the e¤ects of monetary-policy actions on aggregate demand and in ‡ation, monetary-policy actions cannot a¤ect current in ‡ation and output, nor in ‡ation or output in the near future. A rough benchmark is that monetary policy a¤ects output in about a year and in ‡ation in about two years. Therefore, Eurosystem monetary policy has to be guided by in ‡ation forecasts about two years ahead. As discussed further in Svensson [5], for successful policy, the Eurosystem must construct conditional in ‡ation forecasts. These forecasts should depend on all relevant information, including the Eurosystem's view of the transmission mechanism for monetary policy, its view of the current economic and monetary situation within and outside the Euro area, information ¤ Brie…ng paper for the Committee on Economic and Monetary A¤airs (ECON) of the European Parliament for the quarterly dialogue with the President of the European Central Bank.

Expressed views and any errors are solely my own responsibility. 1 As many commentators have suggested, it would be better to formulate this de…nition in an unambiguous and symmetric way as a point in ‡ation target, say 1.5%, possibly with a tolerance interval, §1%.
Evidence for a role of initiation factor 3 in recycling of ribosomal complexes stalled on mRNAs in Escherichia coli

Specific interactions between ribosome recycling factor (RRF) and elongation factor-G (EFG) mediate disassembly of post-termination ribosomal complexes for new rounds of initiation. The interactions between RRF and EFG are also important in peptidyl-tRNA release from stalled pre-termination complexes. Unlike the post-termination complexes (harboring deacylated tRNA), the pre-termination complexes (harboring peptidyl-tRNA) are not recycled by RRF and EFG in vitro, suggesting participation of additional factor(s) in the process. Using a combination of biochemical and genetic approaches, we show that, (i) Inclusion of IF3 with RRF and EFG results in recycling of the pre-termination complexes; (ii) IF3 overexpression in Escherichia coli LJ14 rescues its temperature sensitive phenotype for RRF; (iii) Transduction of infC135 (which encodes a functionally compromised IF3) in E.coli LJ14 generates a ‘synthetic severe’ phenotype; (iv) The infC135 and frr1 (containing an insertion in the RRF gene promoter) alleles synergistically rescue a temperature sensitive mutation in peptidyl-tRNA hydrolase in E.coli; and (v) IF3 facilitates ribosome recycling by Thermus thermophilus RRF and E.coli EFG in vivo and in vitro. These lines of evidence clearly demonstrate the physiological importance of IF3 in the overall mechanism of ribosome recycling in E.coli.
Community as Curriculum.

Although it is spring, snow blankets the schoolyard. Eight-year-old Ashish and his parents, dressed in layers and shivering from the cold, are not used to this climate, having arrived in Canada three weeks earlier from India. Bypassing the schoolyard, they enter Thornwood Public School and report directly to the main office where Lynda Sliz, one of Thornwood’s English as a Second Language teachers, is expecting them. Indeed, she has arranged for an Urdu interpreter to assist with the reception process.
Behavioral Health Risk and Resilience among International Students in the United States: A Study of Socio-demographic Differences

Using a resilience framework, the current cross-sectional study examined indicators of behavioral health risk and resilience among U.S. international students (N=322) across key socio-demographic characteristics. A multimethod approach was used to collect data with both an online platform and paper-based survey instrument. Results showed that higher levels of acculturative stress were reported by older students, females, undergraduates, students who lived with their families, and those who had resided in the US longer than 2 years. Findings underscore the importance of culturally-relevant screening and prevention strategies that target resilience and other protective factors to reduce health risk and encourage well-being and academic success among international students.
Kaempferia parviflora extract increases energy consumption through activation of BAT in mice

Kaempferia parviflora (KP) is a member of the ginger family and is known in Thailand as Thai ginseng, Krachai Dam or Black Ginger. TheK. parviflora extract (KPE) was previously reported to have a number of physiological effects; however, the antiobesity effects of KPE and its mechanisms remain to be elucidated. In this study, we conducted KPE feeding experiments (low dose: 0.5% KPE, high dose: 1.0% KPE) in mice to examine the antiobesity effects. For both 0.5% KPE and 1.0% KPE, 7 weeks’ feeding of KPE contained in a high-fat diet (HFD) significantly decreased body weight gain, intraabdominal fat accumulation, and plasma triglyceride and leptin levels. Concurrently, KPE administration increased oxygen consumption in mice fed on a HFD. We also found that 1.0% KPE feeding significantly increased the uncoupling protein 1 (UCP1) expression in brown adipose tissue (BAT). Moreover, KPE administration increased urinary noradrenaline secretion levels. These results demonstrate that KPE promotes energy metabolism by activation of BAT, at both doses and up-regulation of UCP1 protein at a high dose. Although numerous challenges remain, the present study demonstrated that KPE suppresses HFD-induced obesity through increased energy metabolism.
ERGODIC PROPERTIES FOR A QUANTUM NON LINEAR DYNAMICS FRANCESCO FIDALEO AND CARLANGELO LIVERANI

We present a quantum system composed of innnitely many particles, subject to a non quadratic Hamiltonian, for which it is possible to investigate the long time behavior of the dynamics and its ergodic properties. We do so both for the KMS states and for a large class of locally normal invariant states, whose very existence is already of some interest. 1. Introduction The last years have witnessed a growing interest in the ergodic properties of non relativistic quantum systems. For example, on the one hand a large literature has been devoted to the so called \quan-tum chaos," that is to the study of the spectrum of the Hamiltonians whose classical associated motion enjoys strong ergodic properties (see 12, 16, 28] for an overview). On the other hand, there has been renewed interested in the study of the convergence to equilibrium in quantum systems (i.e. in the study of strong statistical properties directly in the quantum setting) 11, 13, 20, 24, 25, 33]. Of course, in order for such ergodic properties to be present at all, the quantum system must have innnitely many degree of freedom, otherwise only quasi periodic motion can take place. The present paper illustrates, and investigates in details, a simple, but non trivial, class of models of innnite non relativistic quantum systems that exhibit relaxation to equilibrium. Such models are examples of one dimensional harmonic crystals with defects and are akin to the one studied in 8] from a diierent point of view. Indeed, the model consists of an innnite harmonic chain of particles with a special particle

Mas-Mediated Antioxidant Effects Restore the Functionality of Angiotensin Converting Enzyme 2-Angiotensin-(1–7)-Mas Axis in Diabetic Rat Carotid

We hypothesized that endothelial AT1-activated NAD(P)H oxidase-driven generation of reactive oxygen species during type I-diabetes impairs carotid ACE2-angiotensin-(1–7)-Mas axis functionality, which accounts for the impaired carotid flow in diabetic rats. We also hypothesized that angiotensin-(1–7) chronic treatment of diabetic rats restores carotid ACE2-angiotensin-(1–7)-Mas axis functionality and carotid flow. Relaxant curves for angiotensin II or angiotensin-(1–7) were obtained in carotid from streptozotocin-induced diabetic rats. Superoxide or hydrogen peroxide levels were measured by flow cytometry in carotid endothelial cells. Carotid flow was also determined. We found that endothelial AT1-activated NAD(P)H oxidase-driven generation of superoxide and hydrogen peroxide in diabetic rat carotid impairs ACE2-angiotensin-(1–7)-Mas axis functionality, which reduces carotid flow. In this mechanism, hydrogen peroxide derived from superoxide dismutation inhibits ACE2 activity in generating angiotensin-(1–7) seemingly by activating I Cl,SWELL, while superoxide inhibits the nitrergic Mas-mediated vasorelaxation evoked by angiotensin-(1–7). Angiotensin-(1–7) treatment of diabetic rats restored carotid ACE2-angiotensin-(1–7)-Mas axis functionality by triggering a positive feedback played by endothelial Mas receptors, that blunts endothelial AT1-activated NAD(P)H oxidase-driven generation of reactive oxygen species. Mas-mediated antioxidant effects also restored diabetic rat carotid flow, pointing to the contribution of ACE2-angiotensin-(1–7)-Mas axis in maintaining carotid flow.

Autoethnography: a tool for practice and education

Ethnographic techniques are useful tools for developing a fine-grained, context-based understanding of user behavior. Because conventional ethnographic studies are time-intensive, interest has grown in techniques that can be applied more rapidly, to fit within the software development cycle---a sort of 'ethnography lite'. One such promising tool is the autoethnography, in which the investigator creates an ethnographic description and analysis of his/her own behavior, attempting to develop an objective understanding of the behaviors and work context under consideration by casting the investigator as both the informant 'insider' and the analyst 'outsider'. We demonstrate the potential of the autoethnography in HCI education through a case study of an HCI assignment in which autoethnography informs requirements analysis and system design. This paper argues that the autoethnography has a role to play in software development and is a useful teaching tool for HCI courses.
Competitive Equilibria in Semi-Algebraic Economies

This paper develops a method to compute the equilibrium correspondence for exchange economies with semi-algebraic preferences. Given a class of semi-algebraic exchange economies parameterized by individual endowments and possibly other exogenous variables such as preference parameters or asset payoffs, there exists a semi-algebraic correspondence that maps parameters to positive numbers such that for generic parameters each competitive equilibrium can be associated with an element of the correspondence and each endogenous variable (i.e. prices and consumptions) is a rational function of that value of the correspondence and the parameters. This correspondence can be characterized as zeros of a univariate polynomial equation that satisfy additional polynomial inequalities. This polynomial as well as the rational functions that determine equilibrium can be computed using versions of Buchberger's algorithm which is part of most computer algebra systems. The computation is exact whenever the input data (i.e. preference parameters etc.) are rational. Therefore, the result provides theoretical foundations for a systematic analysis of multiplicity in applied general equilibrium.
FOREGONE WITH THE WIND

In an attempt to improve our understanding of the effects of foregone payoffs on learning, the current paper examines the adaptation in decision tasks with a large number of choice alternatives. Our experimental setup varies the feedback about foregone payoffs. Study 1 shows that foregone payoffs can induce strong round–to–round sequential dependencies in the data. Study 2 demonstrates that information about foregone payoffs can impair maximization in a noisy environment, but experience eliminates this negative effect. Study 3 and 4 illustrate a positive effect of foregone payoffs. We investigate whether the common models of adaptive learning (reinforcement learning, fictitious play, EWA, payoff assessment and learning among cognitive strategies) can track this complex pattern.
The importance of friends: social life challenges for foreign physicians in Southern Sweden

ABSTRACT The article connects the fields of work/non-work research with the research on social integration of migrants. It is based on in-depth interviews with foreign physicians in the south of Sweden which explored their work/non-work experiences and their subjective perceptions of managing work, family, social and private domains of life. Based on individual reflections of social life as experienced in the workplace, in the locations of everyday life and transnationally, the analysis does not pursue the existence and composition of social networks but focuses on non-instrumental aspects of social life and explores their significance for high-skilled migrants’ own sense of integration. The findings suggest that migrants who are privileged in terms of education and employment still face extensive challenges in the social domain of life, especially with regard to close friendships. The findings furthermore suggest that social integration is a process that is influenced by place, time and individual life trajectories and therefore cannot be truthfully accounted for by looking at the numbers and ethnic composition of a migrant’s social relations. It is the quality of relations – notably friendships – that matters most.
Do New Objects Capture Attention?

The visual system relies on several heuristics to direct attention to important locations and objects. One of these mechanisms directs attention to sudden changes in the environment. Although a substantial body of research suggests that this capture of attention occurs only for the abrupt appearance of a new perceptual object, more recent evidence shows that some luminance-based transients (e.g., motion and looming) and some types of brightness change also capture attention. These findings show that new objects are not necessary for attention capture. The present study tested whether they are even sufficient. That is, does a new object attract attention because the visual system is sensitive to new objects or because it is sensitive to the transients that new objects create? In two experiments using a visual search task, new objects did not capture attention unless they created a strong local luminance transient.
Individual Investor Activity and Performance

We examine the daily activity and performance of a large panel of individual investors in Sweden's Premium Pension System. We find that active investors earn higher returns and risk-adjusted returns than inactive investors. A performance decomposition analysis reveals that most of the outperformance of active investors is the result of these investors successfully timing mutual funds and asset classes. While activity is beneficial for some investors, extreme flows out of mutual funds affect funds' net asset values negatively for all investors. Financial advisors, by contributing to coordinate investments and redemptions, exacerbate these negative effects.
A Multifactor Model of Stock Returns with Endogenous Regime Switching

We estimate a state-dependent multifactor model with two endogenous states. Its pricing accuracy is slightly superior to that of the Fama and French (1993, 1996) model. We have evidence for dramatically increased factor loadings for distress factors in one state. These results have implications for cost-of-capital calculations, portfolio management, risk analysis and other applications.
Malicious node detection in OppNets using hash chain technique

Opportunistic Networks aim to set a reliable networks where the nodes has no end-to-end connection and the communication links often suffer from frequent disruption and long delays. The design of the OppNets routing protocols is facing a serious challenges such as the protection of the data confidentiality and integrity. OppNets exploit the characteristics of the human social, such as similarities, daily routines, mobility patterns and interests to perform the message routing and data sharing. Packet dropping attack is one of the hardest attacks in Opportunistic Networks as both the source nodes and the destination nodes have no knowledge of where or when the packet will be dropped. In this paper, we present a new malicious nodes detection technique against packet faking attack where the malicious node drops one or more packets and instead of them injects new fake packets. We have called this novel attack in our previous works a packet faking attack. Each node in Opportunistic Networks can detect and then traceback the malicious nodes based on a solid and powerful idea that is, hash chain techniques. In our hash chain based defense techniques we have two phases. The first phases is to detect the attack, and the second phases is to find the malicious nodes. We have compared our approach with the acknowledgement based mechanisms and the networks coding based mechanism which are well known approaches in the literature. In our simulation, we have achieved a very high node detection accuracy and low false negative rate.
Problematic Use of the Internet and Self-Regulation: A Review of the Initial Studies

Problematic Internet Use (PIU) is considered as an inability to control one's use of the Internet, which eventually involves negative consequences in daily life. Among the various psychological factors potentially involved in the development of PIU, the role of poor self-regulation capacities (e.g., high impulsivity and sensation seeking, low inhibitory control, poor decision-making abilities) has recently received increased attention. Although the number of studies currently available on this topic remains limited, our aim here is to review their findings. After briefly defining PIU and discussing the main instruments which have been developed to assess it, this article describes the studies that have investigated the relations between PIU and self-regulation. Their heterogeneous findings are discussed and avenues for future research are provided.
