Mentor Relationships in Clinical Psychology Doctoral Training: Results of a National Survey

Mentor relationships play an important role in the development and promotion of professional identity among psychologists, yet empirical study of mentor-protégé relationships in psychology graduate education is nearly nonexistent. In this study, we provide a contemporary picture of mentor relationships in clinical psychology doctoral programs. We mailed a survey instrument regarding mentor relationships to 1,000 recent doctorates in clinical psychology; nearly 800 responded. Two thirds of respondents reported having a faculty mentor during graduate school. More PhDs reported having a mentor than PsyDs, as did graduates of university-based departments of psychology compared to graduates of schools of professional psychology. Men and women were equally likely to be mentored and to be satisfied with mentor relationships. Ninety-one percent of mentored graduates evaluated the mentor relationship positively, and mentored graduates were significantly more satisfied with their doctoral program. We discuss implications for graduate education.

The purpose of this study is to explore good practice for training convolutional neural networks (CNNs) with spatiotemporal three-dimensional (3D) kernels. Recently, 3D CNNs in the field of action recognition are rapidly developed, and the performance levels of them have improved significantly. However, to date, conventional research has mainly focused on their architecture, and has not sufficiently explored their training configurations. We conduct various experiments with different training configurations on Kinetics, UCF-101, and HMDB-51 datasets to share the knowledge of 3D CNNs for the research community. According to the results of those experiments, the following conclusions could be obtained. (i) Data augmentation by spatiotemporal random cropping improved the performance levels. (ii) Data augmentation by multi-scale spatial cropping increased the accuracies in most cases whereas multi-scale temporal cropping decreased them. (iii) A corner cropping strategy, which is previously shown as a good method for two-stream 2D CNNs, resulted lower accuracies for 3D CNNs compared with simple random cropping. (iv) Freezing early layers of 3D CNNs improved the performance levels when fine-tuning 3D CNNs on a relatively small dataset.
The Effect of Thiosulphate on Arsenic Bioavailability in a Multi Contaminated Soil. A Novel Contribution to Phytoextraction

In this study it was evaluated on a laboratory scale (microcosm), the possibility of using ammonium thiosulphate in assisted phytoextraction for the simultaneous removal of mercury and arsenic from multi- contaminated industrial soil. The species selected were Brassica juncea and Lupinus albus the addition of thiosulfate to the soil greatly promoted the uptake and translocation of both contaminants in the aerial parts of the plants. Mercury concentration in the aerial parts reached in B. juncea 120 mg/kg approximately 40 times the value of the control). The concentration of arsenic also increased significantly in the shoots of B. juncea (14.3 mg/kg), where the value in the control was negligible. Similar trends were obtained for L. albus The results confirmed the known positive effects of thiosulphate in increasing mercury bioavailability for plants, moreover they showed the ability of thiosulphate to mobilize arsenic and significantly to promote its uptake by plants. The increase of arsenic bioavailability, promoted by thiosulfate addition, could be attributed to the competition between arsenate and sulphate ions for the same active sites in the soil surfaces, with the release of arsenic in the soil solution. The use of thiosulfate appears to have great potential since it is a common fertilizer used to promote plant growth and is able to increase the uptake by plants of mercury and arsenic. The simultaneous increase of both contaminants uptake by plants, using a single additive, will provide new insights into the phytoextraction technology in terms of cost and time reduction.
Learning by Doing: The Value of Experience and the Origins of Skill for Mutual Fund Managers

Learning by doing matters for professional investors. We develop a new methodology to show that mutual fund managers outperform in industries where they have obtained experience on the job. The key to our identification strategy is that we look "inside'' funds and exploit heterogeneity in experience for the same manager at a given point in time across industries. As fund managers become more experienced, they pick better stocks, and their trades become better predictors for abnormal stock returns around subsequent earnings announcements. Our approach identifies experience as a first-order driver of observed mutual fund manager skill.
Looking at the soft-bottom around a coastal coral reef: the impact of terrigenous input on Polychaeta (Annelida) community

Fragmentos dos recifes de coral constituem parte do sedimento ao redor dos mesmos, ampliando os limites do recife. Modelos estatisticos foram criados para investigar se a comunidade de poliquetas ao redor do recife Sebastiao Gomes (Banco dos Abrolhos, Brasil) e influenciada pelas caracteristicas do sedimento e/ou pela posicao ao redor do recife, que sao variaveis relacionadas a influencia do aporte terrigeno. Em julho de 2007, periodo dominado por ventos que ressuspendem o sedimento fino da costa para os recifes, amostras de sedimento foram coletadas em quatro transectos perpendiculares ao recife (S, O, N e L). A especie de poliqueta mais abundante foi o carnivoro Goniadides carolinae e o modelo selecionado para descrever a distribuicao desta especie foi muito semelhante aos ajustados tanto para a abundância de macrofauna quanto de poliquetas. Estes modelos apresentaram alta abundância em sedimentos carbonaticos grossos na face do recife exposta aos ventos, onde quase nao ha sedimento terrigeno. Por outro lado, a riqueza de poliquetas nao foi influenciada pela posicao dos transectos. Sebastiao Gomes e um dos muitos recifes costeiros do Banco dos Abrolhos, cuja saude esta prejudicada devido ao aumento de lama relacionada a atividades humanas, como desmatamento e, recentemente, rejeitos da mineracao.
Testosterone supplementation and body composition : results from a meta-analysis study

Objective: The role of testosterone (T) in regulating body composition is conflicting. Thus, our goal is to meta-analyse the effects of T supplementation (TS) on body composition and metabolic outcomes. Methods: All randomized controlled trials (RCTs) comparing the effect of TS on different endpoints were considered. Results: Overall, 59 trials were included in the study enrolling 3029 and 2049 patients in TS and control groups respectively. TS was associated with any significant modification in body weight, waist circumference and BMI. Conversely, TS was associated with a significant reduction in fat and with an increase in lean mass as well as with a reduction of fasting glycaemia and insulin resistance. The effect on fasting glycaemia was even higher in younger individuals and in those with metabolic diseases. When only RCTs enrolling hypogonadal (total T ! 12 mol/l) subjects were considered, a reduction of total cholesterol as well as triglyceride (TGs) levels were also detected. Conversely, an improvement in HDL cholesterol levels as well as in both systolic and diastolic blood pressure was not observed. Conclusion: Our data suggest that TS is able to improve body composition and glycometabolic profile particularly in younger subjects and in those with metabolic disturbances. Specifically designed studies are urgently needed to confirm this point. ed European Journal of Endocrinology (2016) 174, R99–R116
Female infanticide and female-directed lethal targeted aggression in a groupof ring-tailed lemurs ( Lemur catta )

Abstract. We report on extremely rare events of lethal aggression in a semi-captive group of ring-tailed lemurs (Lemur catta) during the birth season 2014. This aggression was targeted against the two highest-ranking females. It led to their eviction from the group and following a final aggressive interaction four days later to their deaths caused by almost all the females and probably even two males of their former group. These events of targeted aggression erupted initially following an infanticide by the highest-ranking female directed at the offspring of a subordinate. Even for ring-tailed lemurs this is a very special case of changeover of power between two different matrilines in a group. In accordance with other studies we suggest that these events of targeted aggression were based on the growing group size and were acts of female reproductive competition during birth season. With the intensity of the events we add new aspects to the existing knowledge of aggressive interactions in ring-tailed lemurs.
Cadmium effects on mineral accumulation, antioxidant defence system and gas exchange in cucumber

The effects of different concentrations (10, 50, 100 and 500 μM) of cadmium (Cd) on manganese (Mn) and iron (Fe), lipid peroxidation, activities of antioxidant enzymes and photosynthetic function were investigated in hydroponically grown cucumber (Cucumis sativus L.). Results indicated that cadmium was accumulated primarily in roots. In the roots and shoots, the cadmium content increased with the increasing cadmium concentrations, and induced decrease of manganese significantly (P < 0.005). The levels of iron had an increasing trend with increasing cadmium concentration and duration of treatment. Cadmium-induced oxidation stress and lipid peroxidation in C. sativus showed by the increased concentration of MDA (malondialdehyde). Cadmium induced higher SOD (superoxide dismutase) and POD (peroxidase) activities than CAT (catalase) activity, suggesting that SOD and POD provided a better defence mechanism against cadmium-induced oxidative damage in C. sativus. The net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO 2 concentration were reduced in the presence of cadmium.
WE EXPECT STOCKS TO RISE, BUT WE DO NOT KNOW WHEN AND WHICH ONES: EXCESSIVE OPTIMISM IN PREDICTING FUTURE STOCK INDICES RETURNS

In this study, we analyze whether: 1) financial professionals manifest lower excessive optimism in predicting future stock indices returns; 2) excessive optimism occurs more when predicting future returns of indices reporting profits than indices reporting losses 3) more long-term predictions are more optimistic than short-term predictions. Three groups of participants (n = 251) – investment managers, financial advisors, and lay men predicted future returns of six stock indices in three forecasting horizons by estimating the 95% confidence intervals. The results showed a high inaccuracy in all three groups. The most accurate group was a group of investment managers, followed by lay men and advisors. We also found that 93% of all incorrect predictions were over-optimistic and excessive optimism was much higher when forecasting stock indices that reported profits in the recent past. The results of this research did not confirm previous findings about inverse effect of expertise in predicting future returns of financial assets.
SIRE-DP-2011-01 Comparing the treatment provided by migrant and non-migrant health professionals : dentists in Scotland

Many OECD countries are increasingly relying on migrants to address shortages of trained health professionals. One key concern is whether migrant health professionals provide equivalent health care. We compare the treatment provided by migrant and non-migrant health professionals using administrative data from the Scottish dental system. A difference-in-differences model is estimated to examine whether migrant dentists respond differently to case mix and individual circumstances as compared with their non-migrant counterparts, and assess the extent to which any differences diminish over time. After controlling for both observed and unobserved differences between individual dentists and the cohort of patients that they treat, we find that migrant dentists have marginally different practice styles, and the variation diminishes over time within two years of practice.

Improving growth and productivity of tomato by some biostimulants and micronutrients with or without mulching

Two field experiments were conducted during 2014 and 2015 growing seasons to assess tomato growth and yield as affected by some biostimulants and micronutrients with or without mulching type. Certain physiological characters were also examined, plant height, the number of branches per plant chlorophyll a, nitrogen %, red fruit weight and total yield per plant as well as fruit firmness and ascorbic acid concentration in fruit was increased in tomatoes under black plastic mulch compared with bar soil. Application of either biostimulants or micronutrient used to increase all growth and yield characters as well as photosynthetic pigments, ions percentage, and fruit quality. Additive effects were shown under mulching, seaweed extract proved to be the most effective in this respect. It could be recommended that spraying tomato crop at 35 and 50 d from transplanting with 500 mg/l seaweed extract under clear or black plastic mulch in order for inducing the highest yield and improve fruit quality.
Stakeholder Salience in Corporate Codes of Ethics - Using Legitimacy, Power, and Urgency to Explain Stakeholder Relevance in Ethical Codes of German Blue Chip Companies

What stakeholder groups are addressed in the German blue chips’ corporate codes of ethics and why do companies concentrate on particular stakeholders? These questions were subject to a study on stakeholder salience in the corporate codes of ethics of the German DAX 30-companies. The extent and the mode stakeholders are addressed in the ethical codes of the companies listed in the German blue chip stock market index were analysed. The empirical results were interpreted in the light of stakeholder salience theory. Stakeholders’ legitimacy, power, and urgency were evaluated against the background of the German business context and the sphere of research on applied business ethics in Germany. The results indicate firstly that companies Using Legitimacy, Power, and Urgency to Explain Stakeholder Relevance in Ethical Codes of German Blue Chip Companies develop a differentiated perception of their environment in terms of their ethical responsibility whereas they clearly distinguish between primary and secondary stakeholders. Secondly, this perception reflects the German business context and, hence, highlights the companies’ embeddedness in a specific environment. Thirdly, stakeholder attributes offered by the stakeholder salience theory are proved to be instrumental for a systematic evaluation of stakeholder relevance. However, the findings point to a different relationship between these attributes than it is proposed by the theory.
Pareto Distributions and the Evolution of Top Incomes in the U.S

This paper presents a dynamic general equilibrium model with heterogeneous firms and entrepreneur's portfolio choice. We analytically show that this model generates the Pareto distribution of top income earners and Zipf's law of firms at the steady state. The differential equation for the probability density distribution of income is derived and numerically evaluated. In the model, CEOs respond to a tax cut by increasing their share of stocks of their own firms, thereby increasing the diffusion of their wealth. The calibrated model shows that the transition path matches with the decline of the Pareto exponent of the income distribution and the trend of top 1% income share in the U.S. in recent decades. We argue that the low marginal income tax at the top bracket of income could lead to the higher dispersion of income among the top income earners, which results in the higher concentration of income in the top income group.
Evaluating the Usability and Learnability of the "Blackboard" LMS Using SUS and Data Mining

Learning management systems (LMSs) provide integrated platforms of various technologies to support instructors and students. Usability evaluation is an essential factor to measure how well technology works for users. The aim of this study is to examine the usability of the LMS in King Abdulaziz University by using some pre-defined usability standards, such as a system usability scale (SUS) questionnaire. A further investigation used data mining techniques (sentiment analysis and clustering) in order to find out the details of any usability problems. The results show that distance education students suffer the most, followed by external students. On the other hand, instructors seem to have a less negative attitude than students towards Blackboard. Overall, the usability of LMSs at KAU is inadequate and needs to be enhanced for all types of users by customising blackboard according to each group.
The 6dF Galaxy Survey: dependence of halo occupation on stellar mass

In this paper we study the stellar-mass dependence of galaxy clustering in the 6dF Galaxy Survey. The near-infrared selection of 6dFGS allows more reliable stellar mass estimates compared to optical bands used in other galaxy surveys. Using the Halo Occupation Distribution (HOD) model, we investigate the trend of dark matter halo mass and satellite fraction with stellar mass by measuring the projected correlation function, wp(rp). We find that the typical halo mass (M1) as well as the satellite power law index (α) increase with stellar mass. This indicates, (1) that galaxies with higher stellar mass sit in more massive dark matter halos and (2) that these more massive dark matter halos accumulate satellites faster with growing mass compared to halos occupied by low stellar mass galaxies. Furthermore we find a relation between M1 and the minimum dark matter halo mass (Mmin) of M1 � 22Mmin, in agreement with similar findings for SDSS galaxies. The satellite fraction of 6dFGS galaxies declines with increasing stellar mass from 21% at Mstellar = 2.6 × 10 10 h −2 M⊙ to 12% at Mstellar = 5.4×10 10 h −2 M⊙ indicating that high stellar mass galaxies are more likely to be central galaxies. We compare our results to two different semi-analytic models derived from the Millennium Simulation, finding some disagreement. Our results can be used for placing new constraints on semi-analytic models in the future, particularly the behaviour of luminous red satellites. Finally we compare our results to studies of halo occupation using galaxy-galaxy weak lensing. We find good overall agreement, representing a valuable crosscheck for these two different tools of studying the matter distribution in the Universe.
Growth and yield of three sunflower hybrids cultivated for two years under Mediterranean conditions

Sunflower (Helianthus annuus L.) is globally one of the most important oil crops, lately expanding in more semi-arid Mediterranean regions. A 2-years field study was conducted to evaluate growth, grain and oil productivity of three sunflower hybrids (PR64E83, Oleko and PR63A90). Plant height, number of green leaves, weight of 1000-grains and grain number were significantly affected by the interaction of year and sunflower hybrid. Grain yield resulted to differences ranged among 13 and 34 % between the two years. In 2009, Oleko and PR63A90 were the most productive hybrids regarding seed (8210 and 7500 kg/ha, respectively) and oil (2960 and 2950 kg ha-1, respectively), while PR63A90 was the significantly more productive hybrid during the second year (2010). Hybrids such as Oleko seem ideal for high grain and oil yield (with a high concentration of monounsaturated fatty acids); however they fit better to a crop rotation, probably due to a high phytotoxicity of their residues which reduces the yield of the second year. On the contrary, the ability of some non high-oleic hybrids such as PR63A90 to keep high grain yield even in the second year of their cultivation in the same field is clearly a very desirable trait and it should be further tested, since it can result to very high oil yield.
Protective Effect of JXT Ethanol Extract on Radiation-Induced Hematopoietic Alteration and Oxidative Stress in the Liver

This study aims at investigating the radioprotective effect of ethanol extract from Ji-Xue-Teng (JXT, Spatholobus suberectus) on radiation-induced hematopoietic alteration and oxidative stress in the liver. Mice were exposed to a single acute γ-radiation for the whole body at the dose of 6.0 Gy, then subjected to administration of amifostine (45 mg/kg) or JXT (40 g crude drug/kg) once a day for 28 consecutive days, respectively. Bone marrow cells and hemogram including white cells, red cells, platelet counts, and hemoglobin level were examined. The protein expression levels of pJAK2/JAK2, pSTAT5a/STAT5a, pSTAT5b/STAT5b, and Bcl-2 in bone marrow tissue; levels of reactive oxygen species (ROS); and the activity of superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) in serum and liver tissue were determined. At the end of the experiment, the effect of JXT on cell viability and G-CSF and G-CSFR levels in NFS-60 cells were tested by CCK-8 assay, ELISA, and flow cytometry. The results showed that the mice exposed to γ-radiation alone exhibited a typical hematopoietic syndrome. In contrast, at the end of the 28-day experiment, irradiated mice subjected to oral administration of JXT showed an obvious improvement on blood profile with reduced leucopenia, thrombocytopenia (platelet counts), RBC, and hemoglobin levels, as well as bone marrow cells. The expression of pJAK2/JAK2, pSTAT5a/STAT5a, and Bcl-2 in bone marrow tissue was increased after JXT treatment. The elevation of ROS was due to radiation-induced toxicity, but JXT significantly reduced the ROS level in serum and liver tissue, elevated endogenous SOD and GSH-PX levels, and reduced the MDA level in the liver. JXT could also increase cell viability and G-CSFR level in NFS-60 cells, which was similar to exogenous G-CSF. Our findings suggested that oral administration of JXT effectively facilitated the recovery of hematopoietic bone marrow damage and oxidative stress of the mice induced by γ-radiation.
Fighting Tax Competition in the Presence of Unemployment: Complete versus Partial Tax Coordination

We analyze the welfare consequences of tax coordination agreements that cover taxes on mobile capital and on immobile labor. In doing so, we take into account two important institutional details. First, we incorporate decentralized wage bargaining, giving rise to involuntary unemployment. Second, we distinguish between complete tax coordination, which effectively covers both tax instruments, and the more plausible case of partial tax coordination, where one tax is marginally increased by all countries, while the other tax rate can still be freely chosen by all countries. It is shown that complete tax coordination remains welfare-enhancing in the presence of unemployment. In contrast, for partial tax coordination, the welfare effect becomes ambiguous and is different to the case of competitive labor markets.
