Talents from Abroad - Foreign Managers and Productivity in the United Kingdom

In this paper, we test the contribution of foreign management on firms' competitiveness. We use a novel dataset on the careers of 165,084 managers employed by 13,106 companies in the United Kingdom in the period 2009-2017. We find that domestic manufacturing firms become, on average, between 7% and 12% more productive after hiring the first foreign managers, whereas foreign-owned firms register no significant improvement. In particular, we test that previous industry-specific experience is the primary driver of productivity gains in domestic firms (15.6%), in a way that allows the latter to catch up with foreign-owned firms. Managers from the European Union are highly valuable, as they represent about half of the recruits in our data. Our identification strategy combines matching techniques, difference-in-difference, and pre-recruitment trends to challenge reverse causality. Results are robust to placebo tests and to different estimators of Total Factor Productivity. Eventually, we argue that upcoming limits to the mobility of foreign talents after the Brexit event can hamper the allocation of productive managerial resources.
HIGH FREQUENCY MAGNITUDE SPECTROGRAM RECONSTRUCTION FOR MUSIC MIXTURES USING CONVOLUTIONAL AUTOENCODERS

We present a new approach for audio bandwidth extension for music signals using convolutional neural networks (CNNs). Inspired by the concept of inpainting from the ﬁeld of image processing, we seek to reconstruct the high-frequency region ( i.e. , above a cutoff frequency) of a time-frequency representation given the observation of a band-limited version. We then invert this reconstructed time-frequency representation using the phase information from the band-limited input to provide an enhanced musical output. We contrast the performance of two musically adapted CNN architectures which are trained separately using the STFT and the invert-ible CQT. Through our evaluation, we demonstrate that the CQT, with its logarithmic frequency spacing, provides better reconstruction performance as measured by the signal to distortion ratio.
Ostracism, Exclusion and Rejection C05.indd

In her 1937 self-portrait Memory, artist Frida Kahlo depicted the anguish roused by her husband’s infidelity with her sister as a metal spike being driven through a gaping hole in her chest. Similarly, when reaching out for words to describe experiences of social loss or rejection, we often clothe our distress in the language of physical pain. A harsh criticism from an admired colleague stings, rejection of romantic overtures hurts, the death of a loved one leaves us heartsick, and the withdrawal of a partner’s love cuts to the core, causing scars. Unlike some other evocative English expressions that do not stand up well to translation, reliance on physical pain metaphors to describe social pain is universal, spanning languages as diverse as German and Inuktitut (MacDonald & Leary, 2005). The universality of this finding raises the question of whether this linguistic tendency reveals something fundamental about the way humans experience threats to social connection. In other words, what is the reason why we gravitate towards physical pain metaphors when describing social distress, or why images like the one evoked by Frida Kahlo resonate so powerfully with audiences around the world, regardless of their language or cultural background? In recent years, an accumulating body of empirical evidence has supported the theory that there is overlap in the neurobiological systems that process physical and social pain (Eisenberger & Lieberman, 2004; Eisenberger, Lieberman, & Williams, 2003; Eisenberger, 2012, 2015; MacDonald & Leary, 2005; Panksepp, 1998). That is, social pain – the emotional response to any negative social event that threatens or damages our sense of connection to other people – shares some neural and neurochemical substrates with physical pain. In this chapter we explain the potential adaptive value of a social injury detection system built on top of a physical pain system, review social neuroscience evidence for the physical-social pain overlap, and explore several implications of such an overlap. We also address some recent criticisms of the physical-social pain overlap theory.
Polar Amplification Due to Enhanced Heat Flux Across the Halocline

Polar amplification is a widely discussed phenomenon, and a range of mechanisms have been proposed to contribute to it, many of which involve atmospheric and surface processes. However, substantial questions remain regarding the role of ocean heat transport. Previous studies have found that ocean heat transport into the Arctic increases under global warming, but the reasons behind this remain unresolved. Here, we investigate changes in oceanic heat fluxes and associated impacts on polar amplification using an idealized ocean‐sea ice‐climate model of the Northern Hemisphere. We show that beneath the sea ice, vertical temperature gradients across the halocline increase as the ocean warms, since the surface mixed layer temperatures in ice‐covered regions are fixed near the freezing point. These enhanced vertical temperature gradients drive enhanced horizontal heat transport into the polar region and can contribute substantially to polar amplification.
Glomerülonefritli hastalarda karotis intima media kalınlığının prediktörü hangisidir; nötrofil-lenfosit oranı mı proteinüri mi?

Seyhun Kürşat, Professor, Celal Bayar University, Department of Internal Medicine, Division of Nephrology, MANİSA, e-mail: seyhun.kursat@ gmail.com (orcid.org/0000-0001-9437-8474) Abstract Purpose: Glomerulonephritis is inflammation of the glomeruli and proteinuria itself is a reflection of the glomerular inflammation. In this study we aimed to investigate the relationship between carotid intima media thickness (CIMT) one of the earliest findings of atherosclerosis and markers of glomerular inflammation. Materials and Methods:40 patients with biopsy proven glomerulonephritis and 46 healthy controls were enrolled in the study. Human Growth arrest spesific protein 6 (Gas6) levels in serum samples were studied by ELISA. CIMT measurement was performed by the same radiologist. Neutrophil-lymphocyte ratio (NLR) was calculated by dividing the number of neutrophils by the number of lymphocytes. Results: The mean age was 42.88±15.41 in patient group and 38.26±9.04 in controls. The mean duration of illness was 29.07±52.90 mounts, proteinuria was 4027.05±4030.22 mg/day, Modification of Diet in Renal Diseases Study Glomerular Filtration Rate (MDRD-GFR) was 53.80±48.32 mL/min/1.73m2. CIMT was 0.62±0.17 mm in patient group, 0.46±0.10 mm in controls. Neutrophil-to-Lymphocyte Ratio (NLR) was 3.69±4.46 in patient group and significantly higher than control group (1.74±0.63). Gas6 levels were statistically higher in control group. CIMT was positively correlated with age, fibrinogen, ferritin, proteinuria and NLR and negatively correlated with HDL cholesterol and Gas6 in glomerulonephritis group. Age was the predictor for CIMT in the logistic regression model. In all group CIMT was positively correlated with age, creatinine, uric acid, fibrinogen, ferritin, CaxP product, proteinuria and NLR and negatively correlated with hemoglobin level, Gas6. In lineer logistic regression analysis carotid IMT was significantly associated with age and ferritin and proteinuria. Conclusion: We have shown that proteinuria is one of the main determinants of increased CIMT independent from the GFR levels in glomerulonephritis with relatively preserved glomerular filtration rate.
EXPERIMENTAL MODAL ANALYSIS OF A FULLY ASSEMBLED PORTUGUESE GUITAR

The most distinctive Portuguese traditional music style is Fado. In this form of Portuguese music a singer is accompanied by two instruments: a classical guitar and a pear shaped plucked chordophone with six courses of double strings – the Portuguese guitar. There are two distinct types of this instrument – the Lisbon and the Coimbra models – named after the towns where the two different styles of Fado have developed. These guitars differ basically on their size and tuning, both comprising 6 orders of double steel strings, while the construction method (strutting patterns, wood species used and soundboard thickness distribution) vary for different builders. As part of a research project that addressed the vibroacoustical behavior of this instrument an experimental modal analysis of a fully assembled Coimbra guitar was performed. In this work we present the results of this analysis showing the main characteristics of the frequency response and significant vibratory modes.
Tardive dyskinesia in mentally retarded patients under long-term antipsychotic treatment -

Objective: Tardive dyskinesia (TD) is an iatrogenic movement disorder, developing due to prolonged use of dopamine receptor blocking agents, that may affect various parts of the body. In a number of studies, prevalence rates between 5 and 30% have been reported. This study aims to research TD in patients with mental retardation who have been hospitalized for a long time and medicated regularly. Method: Included in this study were 40 patients with a diagnosis of mental retardation comorbid with schzophrenia or other psychotic disorders according to DSM-IV TR that had been hospitalized in the chronic patientsâ€™ ward of Bakirkoy Training and Research Hospital for Psychiatry, Neurology and Neurosurgery for a long period. Duration and type of antipsychotics both at the time of interview and over the preceding years were recorded. Dyskinesia was assessed using the Abnormal Involuntary Movements Scale (AIMS). We also used the Simpsonâ€“Angus Rating Scale (SAS) for Parkinsonism. Akathisia was measured using the Barnes Akathisia Rating Scale (BARS). Results: According to AIMS scores, 9 participants (22.5%) received a diagnosis of TD. There was no significant correlation between the type and duration of ongoing or the longest used treatment and the prevalence of TD. There was a statistically significant correlation between the participantsâ€™ age and TD (p=0.009). There were no gender differences for TD Conclusion: We found that long-term use of antipsychotics is unrelated with TD, while age is an important risk factor for TD. It can be said that switching from first generation to second generation antipsychotics does not reduce the prevalence of TD.

This article analyses how the cartoon show Steven Universe both underpins and defies normative understandings of race, gender and able-bodiedness. By referencing theories from feminist, posthumanist, queer, critical race thinking and crip studies, these concepts are considered technologies whose components can be examined, disassembled and reassembled by the technical object that is the cartoon, which is considered a tool whose meaning is co-established by the audience. By using this conceptual framework to analyse the show’s narrative, as well as to create several surveys that seek to comprehend how people’s notions of gender and race may influence the narrative of the show, the article concludes that Steven Universe creates a queer narrative aimed at dismantling contemporary notions of gender, race and able-bodiedness. However, because the show relies on the components that form these technologies to trouble them, it may fall on stereotypical representations if it overlooks the imaginaries embedded on them.
Language Learning in Children Exhibiting Characteristics of Apraxia Using Contextually Mediated Practices

The results of a pilot study assessing the effectiveness of Contextually Mediated Practices (CMP) with children exhibiting apraxic-like characteristics are described in this CASEinPoint. CMP is a promotional approach to early childhood therapy and intervention that uses everyday family and community activities and child interests as contexts of child learning opportunities. Results indicated that using CMP with children exhibiting characteristics of apraxia holds promise for enhancing language competence. Implications for intervention are discussed.
Returns to Experience and the Misallocation of Labor

A recent literature argues that factors of production are misallocated across sectors, types of firms, and locations. In this paper, we: (i) Study wage-experience profiles and obtain measures of returns to experience across these dimensions using data from 23 million individuals in more than 1,000 household surveys and census samples for 145 countries; (ii) Document that returns vary across dimensions in developing countries, which suggests that labor could be misallocated from the perspective of the returns to work experience: services, cognitive occupations, the formal sector, and urban areas exhibit relatively higher returns than non-services, manual occupations, the informal sector, and rural areas, respectively; (iii) Show that despite these “return gaps”, reallocating labor to the best sector/occupation/firm type/location in the country does little to bridge the gap in aggregate returns between developed countries and developing countries; and (iv) Use cross-country data on income, economic and political institutions, and social norms, and find that countrywide characteristics appear to be the main drivers of aggregate returns.

The main purpose of this research is to determine social distances towards alcoholics compared with other high-risk social groups and to check for possible differences in social distances (and stigmatization) of alcoholics with regard to gender and occupation type. On a sample of 230 respondents (a deliberate sample of health and non-health professionals, heterogeneous by socio-demographic characteristics), using the Bogardus social distance scale, we investigated social distances for certain social groups: drug addicts, alcoholics, homosexuals, mentally ill individuals and individuals with physical disabilities. The results have shown that individuals with physical disabilities are the least stigmatized group, while the most stigmatized are drug addicts, with alcoholics being second according to social distance. A similar trend was also found in groups of subjects of different sex as well as different types of occupation, with an exception that alcoholics were the most stigmatized group among health professionals, while drug addicts were second most stigmatized group. Sexual differences in social distance towards alcoholics have not been confirmed, nor the differences between the two observed groups of occupations. The research results provide the basic guidelines needed to design the process of destigmatization of alcoholics, as well as other vulnerable social groups studied, in the populations of both health and non-health professionals of both sexes.
Origin, History and Domestication of Pomegranate

Pomegranate (Punica granatum L.) is one of the ancient fruits associated with several human cultures of the world. There is mention of pomegranate in the Bible, the Koran, and in Buddhist and Chinese arts. Based on evidence from archeo-botanical samples, literature, religious iconography etc., it is estimated that pomegranate might have been introduced into culture about 5000 years ago. According to various reports, wild pomegranate grows in Transcaucasia and Central Asia from Iran and Turkmenistan to northern India. Thus, it is considered to be native of these regions. Its nutritional, therapeutic and ornamental values were known to humans since antiquity. Although pomegranate was reported to have a narrow genetic base, its huge collections available in different parts of the world indicate that it has high genetic diversity among the germplasm. The pomegranate family has a single genus Punica with two species viz., P. granatum and P. protopunica. The latter is considered to be the ancestor of the genus Punica which might have contributed to the evolutionary process of the cultivated form of pomegranate. Since the pomegranate tree is highly adaptive to a wide range of climate and soil conditions, it is grown in different tropical and subtropical regions. However, its main cultivation is confined to the northern hemisphere. Interestingly, the best quality fruits are produced in arid regions. _____________________________________________________________________________________________________________
DEPARTMENT OF ECONOMIC WORKING PAPERS SERIES

The legitimacy of virtual currencies as an alternative form of monetary exchange has been the centre of an ongoing heated debated since the catastrophic global financial meltdown of 2007-2008. We contribute to the relative fresh body of empirical research on the informational market efficiency of cryptomarkets by investigating the weak-form efficiency of the top-five cryptocurrencies. In differing from previous studies, we implement random walk testing procedures which are robust to asymmetries and unobserved smooth structural breaks. Moreover, our study employs two frequencies of cryptocurrency returns, one corresponding to daily returns and the other to weekly returns. Our findings validate the random walk hypothesis for daily series hence validating the weak-form efficiency for daily returns. On the other hand, weekly returns are observed to be stationary processes which is evidence against weak-form efficiency for weekly returns. Overall, our study has important implications for market participants within cryptocurrency markets.
Impacts of gamification on intrinsic motivation

Gamification, commonly defined as “the use of game elements in non-game contexts” (Deterding, Dixon, Khaled & Nacke, 2011), continues to be a topic of interest within the field of user experience (UX) design. The purpose of gamification is usually to increase user engagement, and as a method it seeks to accomplish this through gameful experiences that afford intrinsic motivation in users. However, gamification in practice has thus far been characterized by an emphasis on implementing reward systems commonly found in games through elements such as points, badges and leaderboards (Hamari, Koivisto & Sarsa 2014, Seaborn & Fels 2015). Studies have shown that tangible rewards significantly undermine intrinsic motivation (Deci, Koestner & Ryan, 1999), and this could potentially mean that the reward systems featured in many gamified products and services may in fact harm intrinsic motivation, not enhance it. This literature review aims to assess whether the use of gamification is likely to facilitate or undermine intrinsic motivation, and presents a summary of self-determination theory (Ryan & Deci, 2000), as well as relevant results from empirical studies on the relations between gamification, performance and motivation. All in all, gamification has been shown able to both facilitate and undermine intrinsic motivation through supporting or thwarting the basic psychological needs for autonomy and competence (Ryan & Deci, 2000). This indicates that the effect of motivational affordances is significantly dependent on individual and contextual factors. More research is needed to better describe the factors that affect user motivation in gamified contexts, especially regarding different types of rewards.
Working Paper 210, 2016, Re-pricing of risks and time-variations of the sovereign credit yield curve

How strong has been the effect of the Global Financial Crisis (GFC) on systemic risk in sovereign bond markets? Was the increase in credit spreads relative to triple-A benchmarks which followed the GFC the result of higher sovereign credit risk or the result of a re-pricing that reflected changes in broader market conditions and risk aversion? In this paper we examine these issues by specifying a sovereign credit yield curve which relates sovereign yield spreads to credit ratings and global variables. The model allows for time-variation in both the price of credit risk and the average spread across all rating categories, which proxies the effect of global risk factors on yield spreads. We use daily data of ten-year bond yields and ratings from a large database of 64 countries, covering both emerging markets and developed economies, for the period from 1/1/2000 to 1/1/2015. Our estimates suggest that sovereign risk premia increased significantly after the GFC with most of the increase due to a re-pricing of broader market risks rather than an increase in the quantity or price of sovereign risk per se. This increase in global risk could be the result of a flight-to-quality from lower-rated sovereign bonds to AAA benchmark bonds. Interestingly, we find that global risk in the sovereign bond market is driven by global variables that relate to investor confidence, volatility risk, central bank liquidity and the slope of the yield curve in the US.
