Abstract:
Purpose The purpose of this paper is to test the so-called “Sell in May” effect in globally listed private equity markets based on monthly data covering the period 2004–2017. Design/methodology/approach Ordinary least squares regressions, generalized autoregressive conditional heteroscedasticity regressions and robust regressions are used to investigate the existence of the “Sell in May” effect in globally listed private equity markets. Additionally, the authors conduct robustness checks by dividing the sample period into two subperiods: pre-financial and post-financial crisis periods. Findings The authors find limited statistically significant evidence for the “Sell in May” effect. In particular, the authors observed a statistically significant “Sell in May” effect when taking time-varying volatility into account. These findings indicate that the “Sell in May” effect is driven by time-varying volatility. By contrast, economic significance as measured by visual return inspection and the magnitude of the estimated “Sell in May” coefficients in combination with their positive signs was found to be considerable. Practical implications The findings are important for all kinds of investors and asset managers who are considering investing in listed private equity. Originality/value The authors present a novel study that examines the “Sell in May” effect for globally listed private equity markets by using LPX indices, offering valuable insight into this growing asset class.

Abstract:
Purpose The purpose of this paper is to provide a plausible explanation for the “sell in May” anomaly observed in US stock markets. A heretofore unexplained strategy of selling stock in May and not returning to the market until November has been shown to outperform a simple strategy of buying and holding stock all year long. Design/methodology/approach The authors compare the seasonal performance of three US size-based portfolios for the May–October and November–April periods considering whether or not they were in years with US congressional elections, which occur every two years. Findings While the sell-in-May effect appears to persist in the long run, the authors find that the anomaly is not present in non-election years. There is no significant difference between the May–October and November–April stock returns in non-election years. The observed sell-in-May effect is driven by poor stock returns in the May–October periods leading up to US presidential or congressional elections and subsequent strong performance in the November–April periods immediately following elections. Originality/value The paper offers an election-year effect as an explanation of the sell-in-May anomaly that has been observed in the US stock market. Other possible explanations of the effect, such as seasonal affective disorder, the weather, and daylight savings time, have not gained widespread acceptance.

Abstract:
Sell in May and go away is a phenomenon of return anomaly that starts in May and lasts until October. These months are called the worst months of stocks. Conversely, the months of November to April are often referred to as the best months of the stock where a higher rate of return is achieved throughout the year. Although it has not been proven academically, this phenomenon has been mentioned by various media in Indonesia such as Kontan, CNN Indonesia, and Tempo Business which are predicted to correct the JCI throughout 2017. The purpose of this study is to prove the phenomenon of sell in May and go away on the Indonesia Stock Exchange, and find out whether the average best return of the month is affected by the high return in January. The results prove that even though the average returns increase in November-April was due to the high return in January, but there was no sell in May and go away on the Indonesia Stock Exchange. Under these conditions, the direction of the relationship between risk and return is the opposite that directs the Indonesia Stock Exchange to the efficient market hypothesis.

Abstract:
Sell in May, known also as the Halloween effect, continues to persist in many parts of the world and to puzzle researchers and practitioners. Prior research found that in a few certain countries this effect is not statistically significant or does not exist. This paper shows that although Halloween effect is not significant in Israel, it can be easily replaced by another profitable calendar strategy, holding the market index just for the months of April and December each year and investing the money in the risk-free asset for the rest of the year. This strategy may not persist in the future, however it is puzzling how it prevailed over 20 years since the inception of a prime Tel Aviv market index. We show that the superior performance of this strategy compared to its natural benchmarks is robust using risk-adjusted measures over multiple sub-periods in our sample.

ABSTRACT: We study the joint effects of intercompany investing and reporting of equity method investments on the accuracy and dispersion of analysts' annual earnings-per-share (EPS) forecasts. We compare firm-year observations with and without equity method investments. We posit two non-mutually exclusive explanations for how equity method investments may affect analyst forecast properties. The Opacity Effect posits that the condensed equity method disclosures increase information asymmetry, increasing analysts' forecast errors and forecast dispersion. The Diversification Effect suggests that the diversification of the investor and its investee earnings streams enhances earnings predictability, decreasing analysts' forecast errors and forecast dispersion. Our findings are consistent with both effects operating in the analyst forecasting task. Additional analyses are consistent with the Opacity Effect dominating. This occurrence results, on net, in less accurate and more dispersed forecasts for firm-years with equity method investments. JEL Classifications: G14, M41

Abstract:
This study has applied a geographical perspective with the ambition of evaluating the presence of the Sell in May effect, January effect and monthly anomalies in the Nordic stock markets. In extension the study examines the relationship between corporate size and the returns of calendar anomalies. The study has conducted statistical tests based on Newey-West regressions as well as a Generalized Auto-Regressive Conditional Heteroscedasticity model. The findings suggest that the Sell in May and January are present in the Nordic region and partially abide by theory and results of previous research. The findings suggest that the Sell in May and January effect are independent, however, tendencies when the January effect has a considerable influence on the Sell in May effect are also evident. Additionally, the “April Effect” is an unexpected outlier with positive excess returns that was identified through this study.

A eficiência ou não dos mercados é um assunto que permanece polemizado por diversos acadêmicos e profissionais do mercado, na medida em que alguns sugerem sua eficiência, e outros se mostram contrários a essa ideia. Nesse contexto, o objetivo deste trabalho é o de verificar se os mercados acionários brasileiros podem ser considerados eficientes, na forma fraca, bem como investigar a possiblidade de existência de anomalias de mercado conhecidas como "efeito segunda-feira" e "efeito sell in may and go away". Com a finalidade de verificar a eficiência de mercado, utilizamos os testes de raiz unitária Dickey-Fuller Aumentado (ADF) e Phillips-Perron (PP). Para a constatação de presença do efeito segunda-feira, empregamos dois procedimentos, quais sejam: estimação dos coeficientes de regressão com o uso de variáveis dummies e teste de Wald, para averiguar uma possível igualdade estatística dos coeficientes; e teste F da Anova e teste de Kruskal-Wallis, para verificação de igualdade de médias e medianas, respectivamente. No que concerne à apuração do efeito sell in may and go away, foram utilizados apenas os testes F da Anova e teste de Kruskal-Wallis. Os resultados apresentados sugerem a eficiência do mercado na forma fraca, bem como a não identificação do efeito segunda-feira. No entanto, foi constatada a presença do efeito sell in may and go away para os ativos CSNA3 e USIM5, de acordo com a metodologia proposta, ou seja, uma sazonalidade favorável nos meses de novembro a abril para os respectivos ativos, o que, em suma, contraria a Hipótese de Mercados Eficientes (HME).
The efficiency of the markets or not is a matter that remains polemic by several academics and market professionals, in the sense that some studies suggest its effectiveness, and others show themselves against this idea. In this context, the aim of this work is to verify whether the Brazilian stock markets may be considered efficient in the weak form, as well as investigate the possibility of existence of market anomalies known as “Monday Effect” and “Sell in may and go away Effect”. In order to verify the market efficiency, we used Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root tests. For the observation of Monday effect presence, we employed two procedures, namely: estimation of the regression coefficients using dummy variables and Wald test to investigate a possible statistical equality of the coefficients; and Anova F test and Kruskal-Wallis test to check for equality of means and medians, respectively. Regarding the calculation of Sell in may and go away effect, it was used only Anova F and Kruskal-Wallis tests. The results suggest the market efficiency in the weak form, as well as the no identification of Monday effect. However, it was found the presence of Sell in may and go away effect for the assets CSNA3 and USIM5, according to the methodology proposed, that is, a favorable seasonality in the months from November to April for the respective assets which, in short, contradicts the Efficient Market Hypothesis (EMH).

Abstract:
Studien undersöker om den svenska aktiemarknaden i regel presterar sämre mellan månaderna maj och september enligt den så kallade “ sell-in-may-and-go-away- effekten”. Vi använder den logaritmerade avkastningen för det svenska indexet OMXS30 som delas upp i olika perioder; maj till september, samt oktober till april. Avkastningen för dessa perioder jämförs genom att använda en regressionsmodell. Resultatet från undersökningen visar att effekten är positiv, samt signifikant på en-procentsnivå mellan 1986 till 2017 för OMXS30 iSverige. Studien tittar även på sell-in-may-and-go-away- effektens utveckling, och finner indikationer för att effekten avtar efter publiceringen av Bouman & Jacobsens undersökningav effekten år 2002. Indikationen på att effekten avtar kan betyda en högre grad av rationalitet hos investerare samt en mer effektiv marknad allt eftersom sell-in-may-and-go-away- effekten blir mer allmänt känd. Resultatet för att effekten skulle vara avtagande är dock inte statistisk signifikant och därmed inte heller statistiskt säkerställd.

Abstract:
The use of concrete increasing annually due its favourable properties and readily availability. Demand for concrete will continue to increase and it will remain the world’s most important construction materials for many years to come. However, the use of Portland cement concrete has an environmental burned, and so in a drive to reduce the carbon footprint of construction, there is widespread attention directed towards the utilisation of wastes and industrial by-products to minimise Portland cement (PC) consumption. The cement industry increasingly uses additions, such as fly ash. The literature has established the use of fly ash as partial replacement of Portland cement to increase strength at later age and exhibit considerable enhancement in durability. However, such binders hydrate more slowly, so proper curing conditions become more important. Ideally, the durability of concrete should not be a concern. Some degree of weathering should be expected, but improper concreting procedures can cause the deterioration to be earlier than expected. Furthermore, since durability issues cannot be seen immediately, some assessment of the impact of improper concrete curing is needed. The study has involved casting of concretes prepared with either CEM I or a CEM I blend with 30% replacement with fly ash to investigate the impact of improper curing. Performance was evaluated in terms of compressive strength, drying shrinkage, transport properties and resistance to carbonation. Paste samples were characterised by TGA, XRD and SEM to follow hydration and microstructural development. Also since the degree of saturation is known to affect the compressive strength of concrete, and curing under ambient conditions will lead to changes in the degree of concrete saturation, the work checked the impact of the degree of saturation on compressive strength; to enable an accurate understanding of the impact of improper curing. Improper curing leads to reduced compressive strength development and increased drying shrinkage. Sorptivity and permeability values were increased. This is due to reduced levels of cement hydration, as water evaporates from the concrete surface. The effect of improper curing on resistance to carbonation revealed that samples improperly cured carbonated more than those ideally cured. This study has shown that the impact on sorptivity and permeability is far greater than the impact on compressive strength, with implications for the long-term durability of concrete. Composite cements, containing 30% fly ash, showed comparable strengths to CEM I concretes and improved transport properties when ideally cured. Additions of fly ash reduced the drying shrinkage. Improper curing however led to reduced performance. Strength was compromised by improper curing to a greater degree than for equivalent CEM I mixes. However, it was sorptivity and permeability which were most severely affected. This was due to the reduced degree of cement hydration leading preventing the pozzolanic reaction between the fly ash and portlandite. Also, higher carbonation depth was seen on fly ash samples that were not cured. Low strength concrete, which already has an inherently higher porosity, is more greatly affected by improper curing than high strength concrete. This is presumed to be due to the ease with which water can evaporate from the surface of the more porous matrix. Also, concrete workability has been found to be a factor which can help to reduce the embodied carbon of concrete, with stiffer mixes having lower carbon footprints. However, this study has shown that stiff concrete mixes may be less durable and more susceptible to improper curing. This may be explained by the lower overall water contents within the stiff mixes, and therefore the greater impact of surface water evaporation. The effect of changes in the degree of saturation showed the deleterious effects of improper curing, with the saturated, ambient cured samples all exhibiting lower strengths than the equivalent ideally cured samples. The large capillary pores developed due to improper curing was seen with lower calcium hydroxide contents. The reduced hydration products obtained support the result that lower degree of hydration was produced due to improper curing since the hydration of cement cannot continues in the dry environment. This study confirms the need for good site practice, and shows that embodied carbon should not be the only factor when considering the environmental performance of concrete. Rather, durability and whole life performance should also be considered.

Abstract:
Les matériaux composites à matrice céramique CMC, sont généralement formés d'au moins deux matériaux ayant une forte capacité d'adhésion. Ces matériaux sont principalement composés de renforts fibreux assurant la tenue mécanique de la structure et d'une matrice qui permet sa cohésion. Utilisées principalement dans le domaine de l'aéronautique, elles sont reconnues pour leur bonne tenue mécanique, leur réfractarité élevée tout en conservant une densité faible. Par contre, l'inconvénient majeur associé à ces matériaux est l'apparition de fissures qui sont dues soit au procédé de fabrication soit aux sollicitations mécaniques externes.Dans ce travail, une attention toute particulière est consacrée aux composites à matrice auto-cicatrisante dont la principale propriété est l'aptitude à "réparer" les effets de la fissure par formation d'un verre visqueux.Ces verres visqueux se forment au sein de la fissure grâce à l'oxydation des éléments qui constituent la matrice. Selon la température, différents verres peuvent être formés.Leur fonction est de reboucher les fissures de taille micrométrique de façon à ralentir la diffusion de l'oxygène en direction des fibres et éviter leur rupture par oxydation.Cependant, pour des systèmes en rotation rapide tels que les turbines basse pression des moteurs d'avion (pièce étudiée actuellement), on peut s'interroger quant à la mobilisation du verre visqueux cicatrisant dans un système complexe géométriquement et inhomogène du point de vue de la nature des surfaces. Pour approcher le comportement du verre cicatrisant dans un système modèle mais néanmoins réaliste, une approche de modélisation numérique a été entreprise. L'outil numérique utilisé pour cette étude est le code de calcul Thétis développé à l'I2M. Celui-ci est adapté à ce type de simulation puisqu'il permet la modélisation d'écoulements diphasiques incluant des phénomènes physiques complexes tels que le mouillage. Ainsi, l'objectif de ce travail est-il de déterminer les limites d'utilisation de ce type de matériau en fonction des conditions auxquels il est soumis en évaluant la mobilité du verre cicatrisant dans la fissure.

Abstract:
The purpose of this study was to examine the effects of verbally aggressive messages on women's self-concepts within romantic relationships. Through a qualitative methodological approach, this study examined the effects of such messages in the role of control negotiation, effects on women's self-concepts, and effects on future communication patterns. Through one-on-one interviews, women who have previously been in verbally abusive relationships were given the opportunity to share their individual stories through a narrative analysis. In addition, the theories of Communication Theory of Identity and Relationship Scripts were applied to understand the relationship between the effects of the messages on attitudes, behaviors, sense of identity, and communication patterns of the participants.The results indicated negative effects on victims who have experienced verbally abusive relationships. The need for control exemplified by the male aggressors resulted in compliance by the participants. The participants also experienced lower self-esteem and change or loss of personal identity, which affected communication in subsequent romantic relationships.

Abstract:
Abstract A fundamental assumption of linear acoustics is that the presence of a wave does not have an influence on the properties of the medium through which it propagates. By extension, the assumption of linearity also means that a waveform is stable since any individual wave does not interact with itself. Small modifications in the sound speed due to wave-induced fluid convection (particle velocity) and to the wave’s effect on sound speed through the equation of state can lead to effects that could not be predicted within the limitations imposed by the assumption of linearity. Although a wave’s influence on the propagation speed may be small, those effects are cumulative and create distortion that can produce shocks. These are nonlinear effects because the magnitude of the nonlinearity’s influence is related to the square of an individual wave’s amplitude (self-interaction) or the product of the amplitudes of two interacting waves (intermodulation distortion). In addition, the time-average of an acoustically induced disturbance may not be zero. Sound waves can exert forces that are sufficient to levitate solid objects against gravity. The stability of such levitation forces will also be examined along with their relation to resonance frequency shifts created by the position of the levitated object.

Abstract:
Kinetic energy recovery is a key objective for low pressure exhaust hood design and optimization. Numerical simulation of the exhaust hood helps the engineers to explore and confirm the causes of the loss in the hood. Many studies have suggested that it is necessary for the simulation to include the last stage blade to get a realistic assessment. For the sole exhaust hood study, the inlet boundary condition is hard to set precisely like the downstream flow of the last stage blade. And the studies have also shown that the performances generated from the simulations may vary evidently between the sole exhaust hood and exhaust hood with last stage blade. It is obvious that the blade influences the exhaust hood, but the exact effect factors of the blade and the way they work are not thoroughly discussed. This paper has conducted many numerical tests to audit the influence of the common effect factors of the last stage blade. The internal flow field of the exhaust hood was numerically investigated using three-dimensional Reynolds-Averaged Navier-Stokes (RANS) solutions based on the ANSYS-CFX. In the first part of the paper, the tests are conducted by changing each effect factor of the inlet boundary condition for sole exhaust hood studies. These factors include the mass flow flux, the angle of the exit flow of the last stage, both the circumferential and the radial ones, and the speed and position of the jet-flow downstream of the seal over the shroud of the bucket. The tests show that each factor has its own distinctive style and extent for influence. Some of them may maximize the performance at some certain point, and some may deteriorate the performance rapidly beyond a threshold. And some factors may change the performance insignificantly within a wide range. However, these influences are not good enough to be consistent with the difference between the sole exhaust hood and the hood with blade simulations. In the second part of this paper, the focus locates on the direction of the jet-flow of the bucket seal. The tests prove that this direction is the prominent factor to influence the exhaust hood performance. Some extra tests for the seal have also been conducted to analyze this factor. The static pressure recovery for the simulation with labyrinth seal is about only half of the sole exhaust hood simulation. The discussion of these tests show that the seal jet is the main cause for this performance dive, and explain how the seal jet direction changes the flow field of the exhaust hood. It also suggests that the procedure to optimize the seal design is not mature yet, for some nature of the jet-flow remains unclear. It may need more detailed study in the future.

Full text
Abstract:
Simulations of friction between clean, atomically flat surfaces indicate that the friction force per unit area decreases to zero with increasing area. In previous work, we showed that the presence of mobile atoms between surfaces suppresses this superlubric behavior. The current paper examines the effect of atomic scale roughness. Both single asperities and random self-affine surfaces are considered in two and three-dimensional geometries. We have also examined the effect of commensurability, and elastic or plastic deformation within the bounding solids. The friction force on single asperities decreases to zero as the contact area and radius of curvature increase, but can still be significant at the scale of scanning probe tips. Introducing mobile atoms leads to friction forces that rise linearly with area in large contacts. Frictional forces on random self-affine surfaces can be quite complex. If self-affine scaling extends down to atomic dimensions, the average contact between elastic solids only contains a few atoms and the friction can be large. Plasticity increases contact dimensions and may lower the friction.

Full text
Abstract:
An analytical model is proposed for investigating the effect of non-parallel (wedge) contact on the loosening performance of a preloaded bolt-nut connection under transverse cyclic excitation along the wedge direction. From the model, if the wedge angle is sufficiently small, the self-loosening may take place. On the other hand, if the wedge angle is large enough, the self-loosening caused by the back off rotation may be prevented. Experimental and analytical results show that the proposed model accurately predicts both the self-loosening performance, and it also establishes the requirements for preventing the loosening of the preloaded bolt-nut system.

In ASME 2020 Pressure Vessels & Piping Conference. American Society of Mechanical Engineers, 2020. http://dx.doi.org/10.1115/pvp2020-21208.

Full text
Abstract:
Abstract In nuclear power plants, the sealing performance of reactor pressure vessel is highly related to the spring back properties of the seal ring installed between the closure head flange (upper flange) and the vessel flange (lower flange). In the finite element analysis, the sealing performance is usually described by the separation value of the upper and lower flange at the seal ring. Considered the test results of spring back capability of seal ring in combination with a certain safety factor, the limitation of the separation between upper and lower flange at the seal ring is usually 0.2 mm. There are many design parameters, which have a huge influence on the sealing performance of pressure vessel, such as design size, material performance, bolt preload, etc. As the reactor coolant loop is a complete, and highly relevant design system, some design parameters of pressure vessel changed may affect the whole system. Therefore, the effects of several design parameters on the sealing performance of the pressure vessel were analyzed in this paper. The results indicated that angle of the upper flange seal surface and the preload of the bolts have a big influence on the sealing performance of the pressure vessel, and they have nothing to do with the design of the whole system. The research results might guide the pressure vessel designers to optimize the pressure vessel design on improving the sealing performance.

Full text
Abstract:
Many countries worldwide face significant miss reporting in tax declarations. Miss reporting leads to undesired low revenue and economic distortions. This paper discusses the extent to which the residual bookkeeping burden faced by small firms in simplified regimes influence tax declarations. A randomized control trial among 1,500 irregular firms in Piaui, Brazil showed that adding the tax amount due and records on transactions to a warning notification improved compliance in 21 percentage points and increased the reported revenue in 39 percent. Firms without an accountant were less likely to regularize their status without the added information. These findings suggest the use of third party information to support voluntary compliance may present an opportunity for digital services to improve tax revenue services.

Full text
Abstract:
This paper examines the effects of management practices on effective tax rates (ETR) in a sample of medium and large manufacturing firms in Ecuador. We use a novel data set on management practice scores matched with administrative tax data from the Superintendence of Companies and the Internal Revenue Services of Ecuador based on firms' tax filings. We find that better management practices are positively associated with effective tax rates, defined as the share of tax obligations to profits. This result is robust under various specifications controlling for different covariates, and to different measures of effective tax rates. Furthermore, our findings indicate that the use of fiscal incentives is positively associated with higher effective tax rates. However, firms that use fiscal incentives are able to fatten or reduce their effective tax rates as management practices improved. Overall, our findings suggest that government-sponsored policies that seek to promote better management practices may be self-sustained, if the additional tax revenue expected from better management practices through higher profits is able to cover the cost of the programs.
