EFFECT OF PULSED LASER ABLATION IN WATER ON THE CORROSION BEHAVIOUR AND SURFACE HARDNESS OF STAINLESS STEELS

This work presents the use of pulsed fibre laser ablation in water (PLAW) to study the corrosion behaviour and surface hardness of stainless steels. A stainless-steel plate was ablated with a pulsed ytterbrium-doped fibre laser at a power of 4.2 W. The laserablated sample was subjected to corrosion testing using electrochemical impedance spectroscopy and potentiodynamic polarisation. The results correlated with surface morphology, X-ray diffraction profiles and Vicker’s hardness values. PLAW can enhance the corrosion resistance of stainless steels in both neutral and acidic electrolytes. The corrosion potential of the lasertreated samples was more positive at −126 and −423 mV compared with that of the as-received samples at −209 and −439 mV in neutral and acidic electrolytes, respectively. The inhibition efficiencies of the laser-treated samples in neutral and acidic electrolytes were 98% and 52%, respectively. An improvement in the surface microhardness at a maximum of 8.7% was reported on the fibre laser-ablated stainless steels, thereby demonstrating the efficiency of fibre-laser-assisted PLAW in inhibiting corrosion and improving the hardness of stainless steel.
REMAINING ON CURRENT SOCIAL NETWORK SITES: AN UNCONSCIOUS AND CONSCIOUS PERSPECTIVE

Focusing on social network services (SNSs), this research applies status quo bias (SQB) and proposes a research model for investigating why people continue to use their current SNSs and avoid switching to others. Specifically, this research examined the relationships between habit, interpersonal relationships, inertia, satisfaction, perceived value, and continuance intention. To develop a more efficient research model, this study utilizes conscious interpersonal relationships and unconscious habits as the antecedents of inertia. This study hypothesizes that interpersonal relationships and habit increase an individual’s inertia regarding using an SNS, consequently increasing the individual’s continuance intention. This study also examines whether satisfaction and perceived value moderate the impact of inertia on continuance intention. Data collected from 458 Facebook users provide support for most hypotheses. Our findings indicate that unconscious and conscious factors both affect individuals’ inertia regarding SNS usage; however, unconscious factors are slightly more important than conscious factors. Further, inert users will continue to use their current SNS. In addition, regarding SNS usage, the cognitive evaluation is more important than the unconscious process. The result also indicated that the moderating effect of satisfaction is diminished when perceived value is taken into account. Implications for theory and practice are discussed.
Boian period ceramics from Teleor 008, a site in South of Romania

This paper is about a technological and categorisation assessment of a sample of ceramics from a small site in the Lower Danube Plain, briefly occupied during two phases of the Boian period, all probably dated to the first half of the 5th millennium cal BC. Focusing on fabric use, firing methods and aspects of pottery use, an evaluation of fragmentation and post-deposition patterns helps in assessing the site’s use life.

Concentrându-se asupra compoziției pastei, metodelor de ardere și aspectelor legate de utilizarea ceramicii, o evaluare a modelelor de fragmentare și postdepoziționale contribuie la înțelegerea utilizării sitului.
Mediating Role of Risk Perception between Cognitive Biases and Risky Investment Decision: Empirical Evidence from Pakistan’s Equity Market

Investors are the key players in stock exchange. Sometimes the investor’s decisions are rational and sometimes these decisions consist of irrational behavior. This study examined and explored the impact of cognitive biases on risky investment decision and more specifically the mediating role of risk perception is explored. There are various biases which puteffect on investor decisions but this study explored the combined effect of two biases i.e. heuristic and overconfidence on risk perception, which is mediating variable and also examined the effect of these cognitive biases on risky investment decision. This study is conducted on the investors of Pakistan Stock Exchange. Adapted questionnaires are used. Initially 250 questionnaires were distributed out of which 215 questionnaires were returned. The data is run on SPSS 20. Cronbach’s alpha is used to check the reliability of the instrument. Process macro is applied to check the mediating role of risk perception between cognitive biases and risky investment decision. The study finds a significant relationship between cognitive biases (heuristic and overconfidence) and risky investment decisions. Study also explored that risk perception play a mediating effect between cognitive biases and risky investment decision.
Effects of blockade of muscarinic receptors in the ventral tegmental area : attenuation of cocaine reward, but enhancement of locomotor activity and dopamine overflow in the nucleus accumbens

The present study was designed to determine the involvement of cholinergic projections to the ventral tegmental area in the rewarding effects of cocaine. Bilateral intracranial injections of the muscarinic receptor antagonist atropine into the ventral tegmental area attenuated the rewarding effects of intravenous cocaine self-administered on either fixed ratio or progressive ratio schedules of reinforcement. Low doses of atropine sulphate, the lipophilic form of the drug, produced a compensatory increase in cocaine intake while the administration of higher doses of atropine sulphate extinguished responding for intravenous cocaine on a fixed ratio schedule of reinforcement. Bilateral microinjections of atropine methyl nitrate, the lipophobic form of the drug, into the ventral tegmental area also attenuated the rewarding effects of intravenous cocaine self-administered on a progressive ratio schedule of reinforcement. Responding following the injection of low doses of atropine resembled responding when saline was substituted for cocaine, breaking points were established rapidly and there was no post-reinforcement pause. The priming effect of the cocaine administered during "loading" was abolished by the highest dose of atropine; breaking points were reduced. Enhanced locomotion was the predominant effect on activity induced by the administration of atropine into the ventral tegmental area. Atropine sulphate initially induced a period of immobility that did not occur following the administration of atropine methyl nitrate. Microdialysis techniques were used to assess extracellular dopamine levels in the shell of the nucleus accumbens, the terminal region for mesolimbic dopamine neurons originating in the ventral tegmental area. The injection of atropine methyl nitrate into the ventral tegmental area elevated extracellular levels of dopamine and its metabolites in the ipsilateral nucleus accumbens. Thus blockade of muscarinic receptors in the ventral tegmental area reduces cocaine reward, but increases locomotion and mesolimbic dopamine levels. As cocaine reward is believed to be dopamine-dependent, these findings suggest that separate populations of mesolimbic dopamine neurons underlie cholinergic actions on locomotion and reward.
Geosmithia Species in Florida: Common Fungal Symbionts of Wood-Boring Bark Beetles

Geosmithia are fungi associated with wood-boring bark beetles. Most Geosmithia species do no harm to host trees, but the canker-causing Geosmithia morbida and its beetle vector, the walnut twig beetle, cause the disease complex known as thousand cankers disease on walnut trees. Continuous surveys in Florida have found neither Geosmithia morbida nor its beetle vector in the state, but many native Geosmithia species have been recovered. These native species look similar to the pathogenic fungus but are harmless to their plant hosts. This 4-page fact sheet written by Yin-Tse Huang and Jiri Hulcr and published by the UF/IFAS School of Forest Resources and Conservation provides basic guidelines to sample Geosmithia species in the field and information for distinguishing the plant pathogenic Geosmithia morbida from other Geosmithia species. http://edis.ifas. ufl.edu/fr412
Go Wide or Go Deep? Assortment Strategy and Order Fulfillment in Online Retail

Problem Definition: Expansions in product assortment undertaken by online retailers often engender operational challenges. In undertaking such expansions, retailers exercise a choice between expanding assortment depth or width. We empirically examine the relative impacts of assortment depth and width on a retailer’s order delivery performance and the subsequent effects on sales revenue. We further investigate the role of logistic flexibility in this relationship. Academic/Practical Relevance: Order delivery timeliness is a critical measure of operational success in online retail. The relative impact of expansions in product assortment depth and width on order fulfillment is theoretically unclear thereby making it difficult for managers to choose between these two options from an operational standpoint. We contribute to theory and practice by empirically clarifying the role of assortment strategy on order fulfillment performance. Methodology: Employing a unique panel dataset comprising more than 200 million orders, we study the effects of assortment strategy on delivery timeliness using an instrumental variable approach. We then utilize a two-stage model to estimate the eventual impact of order delivery performance on sales. Furthermore, we employ a matched difference-in-differences approach and a novel Bayesian structural time-series model that exploit the opening of new warehouses to confirm the relationship between delivery timeliness and improved sales. Results: We find that assortment width has a greater negative impact on order delivery timeliness relative to depth. Specifically, adding five subcategories increases average delivery times by 0.21 days. We identify that this is mediated by a proliferation of multi-item orders that induces logistical inefficiencies. Further, these delivery delays result in a 6.0% drop in future sales across all offered subcategories. Managerial Implications: Our study aids managerial-decision making by providing empirical evidence pertaining to the operational consequences of expansions in product assortment and offering insights on potential mitigation strategies.
The impact of corporate QE on liquidity: evidence from the UK

There is substantial uncertainty about the impact of quantitative easing (QE) on market liquidity. Identifying the impact is particularly challenging due to the potential for reverse causality, because liquidity considerations might affect QE purchases. We address this challenge by studying the Bank of England’s 2016-17 Corporate Bond Purchase Scheme (CBPS). In particular, we use granular offer-level data from the CBPS auctions to construct proxy measures for the BoE’s demand for bonds and auction participants’ supply of bonds, allowing us to control for any reverse causality from liquidity to purchases. We find that CBPS purchases improved the liquidity of purchased bonds.

Credibility and trust are partial meditation for both equations.
Looking your Worst: Downward Earnings Management after Activist Challenges

Prior work suggests that firms targeted by contentious activist challenges respond with impression management, promoting positive images of their social performance to maintain audience support. In this paper, we propose that targeted firms face simultaneous incentives to downwardly manage audience members’ impression of their economic performance through negative earnings management. We draw on work in accounting, law, and sociology that suggests that profitability operates as an aggravating cue in punitive assessments and can augment the likelihood of expensive regulatory interventions during periods of political uncertainty. Accordingly, we suggest that firms are motivated to manage their earnings downward when facing contentious challenges. We test this through a longitudinal analysis of firms’ discretionary accruals-based earnings management over the decade spanning 1997-2007. In line with our theory, we find that contentious challenges are associated with significant down-ward adjusted earnings management, and that this is moderated by factors indicating a firm’s general level of non-market risk, including its reputation, the level of political attention directed to it, and regulators’ capacity for monitoring its financial statements.
The Influence of Word of Mouth on Brand Imange and Purchase Intention (A study on the potential customers of Kakiang Garden Cafe Ubud)

The purpose of this study is to determine the influence of word of mouth on purchase intention mediated by the brand image of Kakiang Garden Cafe Ubud. The sample used is 90 respondents which are determined using the purposive sampling method. The data collection technique utilized is by questionnaires with the Likert scale measurement method, while the data are analyzed using the path analysis technique. The research results show that the word of mouth and brand image variable have a positive and significant influence on purchase intention. Likewise, brand image is able to mediate the influence of word of mouth on purchase intention. The management of Kakiang Garden Cafe should be able to make their customers feel comfortable when they make purchases so that the customers can share positive information regarding Kakiang Garden Cafe to other people. This is to enhance the role of brand image by improving the product image of Kakiang Garden Cafe so that there are increases in the purchase intention.
Over-education and Ph.D Graduates in Italy during the Great Recession

This paper evaluates the impact of the Great Recession on Ph.D over-education using data drawn from four annual cohorts of Ph.D graduates surveyed by the Italian National Institute of Statistics. Over-education is examined through the definitions of both overskilling and over-qualification. To assess the effect of the crisis, we adopt several proxies, among which economic resilience. To the best of our knowledge, this is the first time that the nexus over-education-resilience receives attention. The results show that over-skilling is negatively associated with the Great Recession. More generally, working on research-based activities and having study experience abroad are always significant drivers to overcome any kind of job mismatch. Conversely, being self-employed increases the risk of over-education, casting some doubts on the satisfactory additionality of Ph.D employment trajectories beyond academia and research. Finally, in contrast with previous results for graduates, we find that variables related to the family of origins do not exert a significant influence on Ph.D over-education.
Soot oxidation in hydrocarbon-free flames

Title: SOOT OXIDATION IN HYDROCARBON-FREE FLAMES Haiqing Guo, Doctor of Philosophy, 2015 Directed by: Associate Professor Peter B. Sunderland Department of Fire Protection Engineering There are high uncertainties in the existing models of soot oxidation rates. To ameliorate this, soot oxidation in flames was examined using a novel ternary flame system, advanced diagnostics, and a detailed examination of past studies. The ternary flame system comprises a coflowing propylene/air diffusion flame to generate a steady soot column that flows into a hydrogen ring flame. The soot is thereby oxidized in a region far separated from soot formation, which is unlike any past study of soot oxidation in diffusion flames. Nonintrusive optical diagnostics were developed using a digital color camera to measure temperature and soot volume fraction. These diagnostics were validated using a steady laminar ethylene/air diffusion flame and were then applied to the ternary flame. Also measured in the soot flame were velocity, soot primary particle diameter, and stable species concentrations along an axial distance of 45 mm. Temperatures were between 1500 to 1750 K, and O2 partial pressures were between 10 -2 to 10 -1 bar. The soot flame was found to be lean, and its OH (with partial pressures between 10 -4 to 10 -3 bar) was expected to be equilibrated owing to the catalyzed radical recombination in the presence of soot. Soot flux and soot oxidation rates (0.5 to 6 g/m 2 -s) were determined. Soot burnout was 90% at 55 mm height. New soot oxidation mechanisms for O2 and OH were developed from a large body of published soot oxidation measurements. The resulting O2 mechanism has an activation energy of 195 kJ/mol, and the OH mechanism has a collision efficiency of 0.10. Predictions using the new mechanisms are within ±80% of the present measurements in the ternary flame system. SOOT OXIDATION IN HYDROCARBON-FREE FLAMES

Une intoxication aiguë à l'arsenic par voie veineuse

Introduction Lors des intoxications aigues a l'arsenite de sodium, l'absorption se fait generalement par voie orale, plus rarement respiratoire. Pour la premiere fois, une intoxication aigue par voie veineuse est rapportee, avec modelisation pharmacocinetique. Observation Un homme de 38 ans a tente de se suicider par injection intraveineuse d'une solution d'arsenite de sodium. Des son admission a l'hopital, il a ete constate une hypotension arterielle severe associee a des troubles de la repolarisation myocardique, ainsi qu'une diarrhee aqueuse. Un traitement chelateur par dimercaprol a ete interrompu a la 48 e heure du fait d'une insuffisance renale aigue. Onze prelevements successifs ont ete realises dans le sang et les urines. Les cheveux et les ongles ont ete preleves a la 130 e heure. Les dosages ont permis de confirmer la presence de concentrations tres elevees d'arsenic dans tous les prelevements. Les parametres pharmacocinetiques ont ete determines a partir des prelevements sanguins en utilisant un modele bicompartimental avec administration par voie intraveineuse et elimination a partir du compartiment central. Discussion Lors de cette intoxication aigue a l'arsenic par voie intraveineuse, la symptomatologie a ete comparable a celle observee apres une intoxication par voie orale. Le traitement chelateur, bien que precocement interrompu, a tres certainement contribue a la survie. La survenue eventuelle d'autres cas devrait permettre d'adapter les protocoles therapeutiques a ces formes d'intoxication.
