A Close Look at the Structure of the TiO2-APTES Interface in Hybrid Nanomaterials and Its Degradation Pathway: An Experimental and Theoretical Study

The surface functionalization of TiO2-based materials with alkylsilanes is attractive in several cutting-edge applications, such as photovoltaics, sensors, and nanocarriers for the controlled release of bioactive molecules. (3-Aminopropyl)triethoxysilane (APTES) is able to self-assemble to form monolayers on TiO2 surfaces, but its adsorption geometry and solar-induced photodegradation pathways are not well understood. We here employ advanced experimental (XPS, NEXAFS, AFM, HR-TEM, and FT-IR) and theoretical (plane-wave DFT) tools to investigate the preferential interaction mode of APTES on anatase TiO2. We demonstrate that monomeric APTES chemisorption should proceed through covalent Si–O–Ti bonds. Although dimerization of the silane through Si–O–Si bonds is possible, further polymerization on the surface is scarcely probable. Terminal amino groups are expected to be partially involved in strong charge-assisted hydrogen bonds with surface hydroxyl groups of TiO2, resulting in a reduced propensity to react with other species. Solar-induced mineralization proceeds through preferential cleavage of the alkyl groups, leading to the rapid loss of the terminal NH2 moieties, whereas the Si-bearing head of APTES undergoes slower oxidation and remains bound to the surface. The suitability of employing the silane as a linker with other chemical species is discussed in the context of controlled degradation of APTES monolayers for drug release and surface patterning.
INFLUENCE OF DIETARY GLUTAMINE SUPPLEMENTATION ON GROWTH PERFORMANCE, SMALL INTESTINAL MORPHOLOGY, IMMUNE RESPONSE AND SOME BLOOD PARAMETERS OF BROILER CHICKENS

The objective of this experiment was to evaluate the influence of glutamine (Gln) supplementation in the diet of broiler chickens on the growth performance, immune response as well as some blood parameters. Two hundred fifty one day old broiler chickens were allotted into five equal groups (50 chicks per each) of mixed sex. Five experimental diets were formulated to be isonitrogenous and isocaloric with different levels of Gln, first group fed on basal diets without Gln supplementation (control group), while Gln included at 0.5, 1.0, 1.5 and 2.0% and fed to chick groups (2-5) respectively for continuous 6 weeks. The results revealed that 1% Gln supplementation significantly (p < 0.05) improved body weight. Weight gain, Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER) and Efficiency of Energy Utilization (EEU) when compared with the control, while 0.5% Gln supplementation non significantly (p>0.05) improved broiler chick performance and the higher inclusion levels had negative effect on broiler growth performance. Moreover, 1% Gln supplementation significantly (p < 0.05) improved blood pictures, phagocytic activity, antibody production and increase immune organs relative weights, while the lower and higher Gln level had no effect. Chicks fed diet with Gln supplementation at different levels had heavier intestinal relative weights and longer intestinal villi (p < 0.05) as compared with the control. The results indicate that the addition of 1 % Gln to the broiler chick's diet improves growth performance and may stimulate development of the gastrointestinal tract and immune response, while higher level had negative effects.

User experience while viewing stereoscopic 3D television

3D display technologies have been linked to visual discomfort and fatigue. In a lab-based study with a between-subjects design, 433 viewers aged from 4 to 82 years watched the same movie in either 2D or stereo 3D (S3D), and subjectively reported on a range of aspects of their viewing experience. Our results suggest that a minority of viewers, around 14%, experience adverse effects due to viewing S3D, mainly headache and eyestrain. A control experiment where participants viewed 2D content through 3D glasses suggests that around 8% may report adverse effects which are not due directly to viewing S3D, but instead are due to the glasses or to negative preconceptions about S3D (the ‘nocebo effect’). Women were slightly more likely than men to report adverse effects with S3D. We could not detect any link between pre-existing eye conditions or low stereoacuity and the likelihood of experiencing adverse effects with S3D. Practitioner Summary: Stereoscopic 3D (S3D) has been linked to visual discomfort and fatigue. Viewers watched the same movie in either 2D or stereo 3D (between-subjects design). Around 14% reported effects such as headache and eyestrain linked to S3D itself, while 8% report adverse effects attributable to 3D glasses or negative expectations.
Failures in collaborative design with suppliers: Literature review and future research avenues

The focus of the firms on their core competencies associated with the increasing complexity of products due to an integration of various technologies has led to an extension of their New Product Development (NPD) activity across organisational boundaries. In this respect, it is now acknowledged that Early Supplier Involvement (ESI) in product development confers a competitive advantage. Nevertheless appraising the benefits of such collaboration on the product development performance is not easy. Our method is based on the "glitch" concept that enables to appraise ESI benefits from the opposite direction i.e. by identifying what happens when the collaboration with suppliers is absent. Our previous work presented at IPSERA 2011 dealt with an in-depth case study analysis of an unsuccessful collaborative development with a supplier. In this previous paper, we identified ten "glitches" that prevented from reaping the benefits of supplier involvement. The aim of this paper is to carry out a literature review about failures in collaborative development of new product between a customer and a supplier. By comparing those literature review results with case study results, we aim at proposing a classification of the failures currently encountered in collaborative development with suppliers in order to tackle them.
Active Avoidance Learning Requires Prefrontal Suppression of Amygdala-Mediated Defensive Reactions

Signaled active avoidance (AA) paradigms train subjects to prevent an aversive outcome by performing a learned behavior during the presentation of a conditioned cue. This complex form of conditioning involves pavlovian and instrumental components, which produce competing behavioral responses that must be reconciled for the subject to successfully avoid an aversive stimulus. In signaled AA paradigm for rat, we tested the hypothesis that the instrumental component of AA training recruits infralimbic prefrontal cortex (ilPFC) to inhibit central amygdala (CeA)-mediated Pavlovian reactions. Pretraining lesions of ilPFC increased conditioned freezing while causing a corresponding decrease in avoidance; lesions of CeA produced opposite effects, reducing freezing and facilitating avoidance behavior. Pharmacological inactivation experiments demonstrated that ilPFC is relevant to both acquisition and expression phases of AA learning. Inactivation experiments also revealed that AA produces an ilPFC-mediated diminution of pavlovian reactions that extends beyond the training context, even when the conditioned stimulus is presented in an environment that does not allow the avoidance response. Finally, injection of a protein synthesis inhibitor into either ilPFC or CeA impaired or facilitated AA, respectively, showing that avoidance training produces two opposing memory traces in these regions. These data support a model in which AA learning recruits ilPFC to inhibit CeA-mediated defense behaviors, leading to a robust suppression of freezing that generalizes across environments. Thus, ilPFC functions as an inhibitory interface, allowing instrumental control over an aversive outcome to attenuate the expression of freezing and other reactions to conditioned threat.

Modifying SEBAL Model Based on the Trapezoidal Relationship between Land Surface Temperature and Vegetation Index for Actual Evapotranspiration Estimation

The Surface Energy Balance Algorithm for Land (SEBAL) is widely used to estimate actual evapotranspiration (ETa). One major limitation of the SEBAL model is the subjectiveness in selecting extreme cold/hot pixels. In the present study, the SEBAL model is modified by determining the extreme cold/hot status, based on the theoretical trapezoidal relationship between land surface temperature (Ts) and Enhanced Vegetation Index (EVI), which is established for each pixel. In this way, the dependence of SEBAL model on the existence of extreme cold/hot status and the subjectiveness in selecting cold/hot pixels with SEBAL model are eliminated. The performance of the classical SEBAL model and the modified version, T-SEBAL, are compared for estimating ETa for a semi-arid catchment, and the result showed that the accuracy of ETa estimation is improved by the T-SEBAL model compared with the classical SEBAL model.
The mediating role of authentic leadership between the relationship of employee training and employee performance

Article history: Received: October 7, 2018 Received in revised format: November 29, 2018 Accepted: December 16, 2018 Available online: December 18, 2018 The primary objective of the study is to investigate the mediating role of authentic leadership between employee training and employee performance in Jeddah Islamic Port of Kingdom of Saudi Arabia based on the complementary congruity theory (CCT). The study is based on analyzing 212 respondents from Jeddah Islamic Port employees. The present study uses the smartPLS 3.2. 8 statistical software to reach a positive and significant relationship between employee training, authentic leadership and employee performance. Furthermore, the study finds a mediating role of authentic leadership between the relationship of employee training and employee performance in Jeddah Islamic Port. The study also recommends that the port management should focus on employee training and authentic leadership practices to enhance the employee performance which lead to port performance. Moreover, the study suggests that future study should validate the current study framework in other countries especially in the context of government departments. © 2019 by the authors; licensee Growing Science, Canada
How to prevent unhelpful personality traits from evolving into unhelpful financial behaviors: The benefits of future clarity

Many organizations have implemented programs to improve the financial behavior of impending retirees and other vulnerable demographics. These programs are predicated on the assumption that financial behavior is indeed modifiable. Yet, many enduring traits, such as emotional instability, could promote financial anxiety and provoke imprudent financial behaviors, limiting the utility of these programs. This study, however, tests the possibility that future clarity—the degree to which individuals perceive their future as vivid and certain—could diminish the extent to which emotional instability coincides with financial anxiety and imprudent financial behavior. Specifically, 1,516 participants over age 50 completed a questionnaire that gauges emotional instability, future clarity, financial anxiety, and financial behaviors. Future clarity did indeed diminish the extent to which emotional stability was related to financial anxiety but not financial behavior. Thus, programs that are designed to improve financial literacy should also help individuals clarify their future career and life aspirations.
Influence of aortic pressure-induced homeometric autoregulation on myocardial performance.

CLANCY, RICHARD L. , THOMAS P. GRAHAM, JR., JOHN Ross, JR., EDMUND H. SONNENBLICK,AND EUGENE BRAUNWALD. InJuence of aortic pressure-induced homeometric autoregulation on myocardialperformance. Am. J. Physiol. 214(5) : 1186-l 192. 1968.The alteration in left ventricular (LV) performance following aortic pressure-induced homeometric autoregulation, defined by a fall in LV end-diastolic pressure after a sudden increase in aortic pressure (AP), was assessed in terms of the mechanics of LV contraction. The relative contributions of the accompanying Frank-Starling mechanism and altered contractility, or inotropic state, were measured from the force-velocity (F-V) relations of single isovolumic contractions in a dog right-heart bypass preparation, the relations during homeometric autoregulation and during increased LV filling at constant aortic ‘pressure being compared at equal LV end-diastolic circumferences (LVEDC). Mean values following the homeometric autoregulatory response and during increased LV filling were, respectively : mean AP 113 and 78 mm Hg, LVEDC 20.2 and 20.2 cm, LVEDP 8.7 and 9.9 mm Hg, and stroke volume Il.3 and 18.9 ml. The isovolumic F-V curves were shifted to the right following AP elevation, maximum stress and contractile element velocity being 7.4 and 7.3% larger than during increased LV filling. These results suggest that the increase in LV performance during the steady state after pressure-induced homeometric autoregulation has occurred is associated with a small augmentation of LV contractility, but that the major effect results from the operation of the Frank-Starling mechanism.
Decolonizing Privacy Studies

This paper calls for an epistemic disobedience in privacy studies by decolonizing the approach to privacy. As technology companies expand their reach worldwide, the notion of privacy continues to be viewed through an ethnocentric lens. It disproportionately draws from empirical evidence on Western-based, white, and middle-class demographics. We need to break away from the market-driven neoliberal ideology and the Development paradigm long dictating media studies if we are to foster more inclusive privacy policies. This paper offers a set of propositions to de-naturalize and estrange data from demographic generalizations and cultural assumptions, namely, (1) predicting privacy harms through the history of social practice, (2) recalibrating the core-periphery as evolving and moving targets, and (3) de-exoticizing “natives” by situating privacy in ludic digital cultures. In essence, decolonizing privacy studies is as much an act of reimagining people and place as it is of dismantling essentialisms that are regurgitated through scholarship.
Revived Beauty: Research into Aesthetic Appreciation of Materials to Valorise Materials from Waste

The use of materials derived from waste is one of the prominent ways to contribute to sustainable product design. However, there is a stark gap in literature concerning how people appraise such materials. In this paper, we present our initial attempts to understand the aesthetic appreciation of materials, in particular those derived from discarded raw materials, i.e., revived materials. Two studies were conducted for which we took the aesthetic principle unity-in-variety as the departure point. In the first study, we explored material appraisals by testing whether different visual and tactile qualities interrelate with each other in a similar or contradictory way. Based on these findings, two revived materials were modified and our main assumptions were further explored in Study 2. We outline our findings and show that the aesthetic appreciation of a material can be influenced by the (in)congruity between visual and tactile qualities of the material.
What happened to critical pedagogy in physical education? An analysis of key critical work in the field

Despite a long history of critical scholarship in physical education (PE), current research continues to show that PE is an exclusionary and marginalising space for many students. Hawkins suggests that philosophical pragmatism, cultural materialism, and health concerns are driving the field, to the extent that the foundations of PE are in jeopardy, and even in ‘crisis’. These trends are at odds with poststructuralist approaches to the field, and with (continued) calls for critical pedagogical practice. In this article, I reflect on these issues and consider four different approaches to critical pedagogy in the work of: Richard Tinning; Laura Azzarito; my own work with a teacher called Dan; and Kim Oliver and David Kirk. Drawing on this scholarship, I argue that critical practice is needed now more than ever, and I offer some thoughts about the future of this work.
Horizontal Inequalities and Civil Conflict

A surimi product comprising a surimi, and a hydroxypropyl starch hydrolyzate product, a spherical dextrose product, or a mixture thereof as a cryoprotectant, is disclosed. The cryoprotectant is present in a sufficient amount to prevent significant freeze-induced denaturation of proteins during storage of the surimi product, and thereby maintain protein functionality to allow use of the surimi product in the manufacture of foodstuffs.
In vitro and in vivo anti-cancer activities of Kuding tea (Ilex kudingcha C.J. Tseng) against oral cancer

Kuding tea (Ilex kudingcha C.J. Tseng) is drunk widely in China. The in vitro anticancer effects of Kuding tea were evaluated in TCA8113 human tongue carcinoma cells using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. At a concentration of 200 μg/ml, Kuding tea exhibited an inhibitory effect of 75% in TCA8113 cells, which was higher than that observed at concentrations of 100 and 50 μg/ml (41 and 10% inhibition, respectively). Reverse transcription-polymerase chain reaction (RT-PCR) and western blot analyses of the apoptosis, inflammation and metastasis genes and proteins in Kuding tea-treated cancer cells were performed. Kuding tea significantly induced apoptosis in TCA8113 cancer cells (P<0.05) by upregulating Bax, caspase-3 and caspase-9 expression, and downregulating Bcl-2 expression. Expression of the NF-κB, iNOS and COX-2 genes that are associated with inflammation was significantly downregulated by Kuding tea, which demonstrated its anti-inflammatory properties. Kuding tea also exerted an anti-metastatic effect on cancer cells. This was demonstrated by the decreased expression of matrix metalloproteases (MMPs) and the increased expression of tissue inhibitors of metalloproteinases (TIMPs), and confirmed by the inhibition of the metastasis of U14 squamous cell carcinoma cells in imprinting control region (ICR) mice. The ICR mouse buccal mucosa cancer model was established by injecting the mice with U14 cells. Following injection, the wound at the injection site was topically treated with Kuding tea. It was observed that the tumor volumes for the group treated with Kuding tea were smaller than those from the control mice. Analysis of the sections of buccal mucosa cancer tissue demonstrated that the buccal mucosa cancer degrees of the Kuding tea-treated mice were weaker than that in the control mice. Similar results were observed in the lesion sections of the cervical lymph nodes. Based on these results, Kuding tea exhibited successful in vitro anticancer effects in TCA8113 cells and in vivo buccal mucosa cancer preventive activity.
A variable Quasi‐Periodic Oscillation in M82 X‐1. Timing and spectral analysis of XMM–Newton and RossiXTE observations

We report results from a spectral and timing analysis of M82 X-1, one of the brightest known ultraluminous X-ray sources. Data from a new 105-ks XMM-Newton observation of M82 X-1, performed in 2004 April, and of archival RossiXTE observations are presented. A very soft thermal component is present in the XMM spectrum. Although it is not possible to rule out a residual contamination from the host galaxy, modelling it with a standard accretion disc would imply a black hole (BH) mass of ≈ 10 3 M ⊙ . An emission line was also detected at an energy typical for fluorescent Fe emission. The power density spectrum of the XMM observation shows a variable Quasi-Periodic Oscillation (QPO) at frequency of 113 mHz with properties similar to those discovered by Strohmayer and Mushotzky. The QPO was also found in seven archival RXTE observations, that include those analysed by Strohmayer and Mushotzky, and Fiorito and Titarchuk. A comparison of the properties of this QPO with those of the various types of QPOs observed in Galactic black hole candidates strongly suggests an association with the type-C, low-frequency QPOs. Scaling the frequency inversely to the BH mass, the observed QPO frequency range (from 50 to 166 mHz) would yield a BH mass anywhere in the interval few tens to 1000 M ⊙ .

Fragility of CVaR in portfolio optimization

Abstract We evaluate conditional value-at-risk (CVaR) as a risk measure in data-driven portfolio optimization. We show that portfolios obtained by solving mean-CVaR and global minimum CVaR problems are unreliable due to estimation errors of CVaR and/or the mean, which are aggravated by optimization. This prob- lem is exacerbated when the tail of the return distribution is made heavier. We conclude that CVaR, a coherent risk measure, is fragile in portfolio optimization due to estimation errors.
