Who moved my cheese?
Venue: Australian and New Zealand journal of public health

Who Moved My Cheese is about change and how people react and respond to change. Briefly, the book talks about four people who find their way through a maze to a large cache of cheese. Each day they find their way back to the cheese and eat happily away. They become accustomed to finding the cheese in the same place, and come to expect it. One day, as you might have guessed, the cheese is gone. No more cheese. The four people, Sniff, Scurry, Hem and Haw, react quite differently to the new situation. As you read through the book, you see yourself in one or more of the people. It allows for some interesting reflection. I'm not going to tell you which one of the characters I saw in myself.
Non catalyzed one step synthesis of ammonia from atmospheric air and water

It is well known that ammonia is produced through a catalytic reaction at high temperature and pressure from pure nitrogen and hydrogen. This catalytic chemical process is a massive and high energy consuming process, but a very important one for nitrogen fixation. Here, we show a non catalyzed one step synthesis of ammonia from atmospheric air (nitrogen source) and water (hydrogen source) based on an interfacial reaction between the air plasma gas phase and the water phase, at 25 degC and atmospheric pressure. In the plasma/liquid interfacial reaction (P/L reaction) atomic nitrogen in both air plasma and nitrogen plasma first abstracts hydrogen from the water phase surface at the P/L interface, and then NH is produced without any catalyst. Transiently formed NH is reduced further at the water phase, affording NH3, which then dissolves in the water phase. The P/L reaction may provide an alternative solution that enables both energy conservation and CO2 emission reduction.
Cosmochemical implications of CONSERT permittivity characterization of 67P/CG

Analysis of the propagation of the CONSERT signal throughout the small lobe of 67P/CG nucleus permitted to deduce the real part of the permittivity, at a value of 1.27+ 0.05  The first interpretation of this value using the dielectric properties of mixtures of ices (H 2 O, CO 2 dusts and porosity, led to the conclusion that the comet porosity ranges between 75 85% In addition, the dust to ice ratio was found to range between 0.4 2.6 and the permittivity of dust (including 30% of porosity) was determined to be lower than 2.9. This last value corresponds to a permittivity lower than 4 for a material without any porosity. This paper is intended to refine the dust permittivity estimate by taking into account the updated values of nucleus densities and dust/ice ratio, and to provide further insights into the nature of the constituents of comet 67P/CG. We adopted a systematic approach: determination of the dust permittivity as a function of the Ice Dust and Vacuum (i.e. porosity) volume fraction and comparison with the permittivity of meteoritic, mineral and organic material from literature and laboratory measurements. Then different composition models of the nuclei corresponding to cosmochemical endmembers of 67P/CG dust are tested. For each of these models the location in the I/D/V diagram is calculated based on available dielectric measurements, and confronted to the locus of 67P/CG. The number of compliant models is small and the cosmochemical implications of each are discussed to conclude on a preferred model  An important fraction of carbonaceous material is required in the dust in order to match CONSERT permittivity observations, establishing that comets represent a massive carbon reservoir.

Probing into the binding interaction between medroxyprogesterone acetate and bovine serum albumin (BSA) spectroscopic and molecular docking methods.
Venue: Luminescence the journal of biological and chemical luminescence

To further understand the mechanism of action and pharmacokinetics of medroxyprogesterone acetate (MPA) the binding interaction of MPA with bovine serum albumin (BSA) under simulated physiological conditions (pH 7.4) was studied using fluorescence emission spectroscopy, synchronous fluorescence spectroscopy, circular dichroism and molecular docking methods. The experimental results reveal that the fluorescence of BSA quenches due to the formation of MPA BSA complex. The number of binding sites (n) and the binding constant for MPA BSA complex are ~1 and 4.6 x 10(3) M( 1) at 310 K, respectively. However, it can be concluded that the binding process of MPA with BSA is spontaneous and the main interaction forces between MPA and BSA are van der Waals force and hydrogen bonding interaction due to the negative values of DG(0) DH(0) and DS(0) in the binding process of MPA with BSA. MPA prefers binding on the hydrophobic cavity in subdomain IIIA (site II' of BSA resulting in a slight change in the conformation of BSA, but BSA retaining the a helix structure.
The Relationship of Acculturation Strategies to Resilience: The Moderating Impact of Social Support among Qiang Ethnicity following the 2008 Chinese Earthquake
Venue: PloS one

International research has mostly confirmed the positive association between acculturation strategies and resilience in ethnic groups, but the mediating and moderating mechanisms underlying the relationships are still under investigated. The present study aimed to investigate the associations between acculturation strategies (based on two cultural identities) and resilience of 898 Qiang ethnicity volunteers (mean age 29.5) especially exploring the mediating and moderating effects of personality, spiritual belief and social support on the relationship between acculturation strategy (using two cultural identities as latent variables in model analysis) and resilience following the occurrence of 2008 Wenchuan earthquake in Sichuan, taking such mechanisms into account. Results were as follows: (1) All variable presented significant positive correlations; (2) Consistent with the mediating hypotheses, personality and spiritual beliefs played a partial mediating role in the relationship between two cultural identities and resilience; (3) High or low level of perceived social support had a moderating effect on cultural identities and resilience; (4) The integration strategy was the most optimal style to promote the development of resilience, but marginalization was the least effective style.
Cultural revitalisation after catastrophe: the Qiang culture in A'er

The culture of the Qiang ethnic minority in Western China has been threatened by assimilation with the majority culture, and many Qiang no longer take part in traditional ceremonies or use their cultural skills and knowledge. The devastating 2008 earthquake in Sichuan killed a 10th of the Qiang population and destroyed monuments, houses and villages. The Beijing Cultural Heritage Protection Centre (CHP) a citizen volunteer non governmental organisation, launched a project to help a Qiang village named A'er preserve its intangible and tangible cultural heritage. This paper describes the damage that was done and the needs of the Qiang people in the remote village of A'er, which is generally considered one of the last major repositories of traditional Qiang culture. The A'er people, despite their desperate situation, were determined to save their cultural heritage. The CHP team, working with them, provided necessary instruments and methods for recording. The Qiang people of A'er village themselves decided what they would record and produced an introduction to the A'er Qiang culture named 'The A'er Archive' and an elementary conversation booklet over which A'er villagers explicitly maintained copyright.
How competitiveness may cause a gender wage gap: Experimental evidence

We show that choices in competitive behavior may entail a gender wage gap. In our experiments, employees first choose a remuneration scheme (competitive tournament vs. piece rate) and then conduct a real effort task. Employers know the pie size the employee has generated, the remuneration scheme chosen, and the employee's gender. Employers then decide how the pie will be split, as in a dictator game. Whereas employers do not discriminate by gender when tournaments are chosen, they take substantially and significantly more from female employees who choose piece rate remuneration. A discriminatory wage gap occurs which cannot be attributed to employees' performance.
Mobile Data Gathering with Load Balanced Clustering and Dual Data Uploading in Wireless Sensor Networks

In this project, a framework which consists of three layers is introduced for the mobile data gathering in the wireless sensor networks. The three layers of the framework are given as the sensor layer, clustered head layer, mobile collector layer (also called as SenCar) This framework is made use of with a LBC DDU, which is called as the load balanced clustering and the dual data uploading. The main aim of employing this project is to get a good scalability and a long lifetime for the required network and for the lower data gathering recess.
Distributed fault tolerant control for a class of cooperative uncertain systems with actuator failures and switching topologies
Venue: Inf. Sci.

This paper studies the distributed fault tolerant control (DFTC) problem for a class of high order multi agent systems (MASs) with switching undirected topologies, heterogeneous matching uncertainties, disturbances and actuator faults including loss of effectiveness, bias, outage and stuck. In this frame work, the communication network of dynamic agents may switch among several undirected connected graphs. It is assumed that the actuator efficiency factors, the lower and upper bounds of the time varying failures and heterogeneous uncertainties, disturbances and the leader's control input signal, are unknown. Based on the relative information of neighbors, a novel fault tolerant consensus tracking protocol is designed for each follower node via distributed adaptive mechanism. By utilizing the multiple Lyapunov functions method and algebraic graph theory, a sufficient condition for consensus tracking is established. Furthermore, it is proved that if the topology dwell time is larger than a positive threshold, the state of each follower node synchronizes to that of the leader with a bounded residual error in the presence of actuator faults, heterogeneous matching uncertainties and disturbances. Finally, two numerical examples are given to show the effectiveness of the proposed control scheme.
Revisiting Software Engineering in the Social Era
Venue: Int. J. Syst. Serv. Oriented Eng.

This paper discusses the possible changes that software engineering will have to go through in response to the challenges and issues associated with social media. Indeed, people have never been so connected like nowadays by forming spontaneous relations with others even strangers and engaging in ad hoc interactions. The Web is the backbone of this new social era an open, global, ubiquitous, and pervasive platform for today's society and world suggesting that "everything" can socialize or be socialized. This paper also analyzes the evolution of software engineering as a discipline, points out the characteristics of social systems, and finally presents how these characteristics could affect software engineering's models and practices. It is expected that social systems' characteristics will make software engineering evolve one more time to tackle and address the social era's challenges and issues, respectively.
The relationship between nature relatedness and anxiety
Venue: Journal of health psychology

This study investigated the relationship between anxiety and feelings of being connected to nature. Two standardised self report scales, the Nature Relatedness Scale and the State Trait Inventory for Cognitive and Somatic Anxiety, were used in tandem with a qualitative question. Quantitative results indicated that connection to nature was significantly related to lower levels of overall, state cognitive and trait cognitive anxiety. Qualitative results revealed seven themes: relaxation, time out, enjoyment, connection, expanse, sensory engagement and a healthy perspective. Taken together, these results suggest that opportunities that enhance experiences of being connected to nature may reduce unhelpful anxiety.

Change and correlates of resilience in high school students in Hong Kong: findings based on six waves of longitudinal data

Based on six waves of longitudinal data collected from high school students, the study examined developmental pattern and correlates of resilience in adolescents in Hong Kong. Over 6 years, the students were invited to complete a questionnaire containing measures of psychosocial functioning including family functioning, parent child subsystem quality and resilience. There was a slight decrease of resilience throughout adolescence. Adolescents having better parent child subsystem quality and family functioning reported higher levels of resilience initially. However, better mother child subsystem quality and family functioning were significantly associated with faster decrease in resilience, although adolescents with better parent child subsystem quality and family functioning always reported higher resilience levels over 6 years. The findings suggest that strengthening family processes can help to promote resilience in adolescents in Hong Kong.
A 6 year longitudinal study of social competence amongst Chinese adolescents in Hong Kong

In response to the severe lack of longitudinal data on adolescent development, we conducted a 6 year longitudinal study examining the change and psychosocial correlates of social competence in Chinese adolescents in Hong Kong. During the high school years (Secondary 1 to Secondary 6) participants responded to measures of social competence, socio demographic characteristics (gender, family intactness and economic disadvantage) and family processes (father child relational quality, mother child relational quality and family functioning) Results showed that social competence dropped across the six waves. While gender, father child subsystem quality, mother child subsystem quality, and family functioning significantly predicted social competence at the initial level, rate of decrease in social competence was greater for adolescents who came from intact families, had better mother child subsystem quality, and reported better family functioning. Economic disadvantage was the only factor that did not affect the development of social competence in adolescents.
Pricing Coupon Bond Options and Swaptions under theTwo Factor Hull White Model

In this article, we propose an alternative approach for pricing bond options and swaptions under the two factor Hull White model that differs from existing models used to evaluate these instruments. Assuming that the forward price of a coupon bond is a martingale under the forward risk neutral measure, the proposed model involves deriving the volatility of the coupon bond as a function of the stochastic durations calculated with respect to the model's two factors. Once the volatility function is defined, the price of options on coupon bonds can be derived by simply applying standard no arbitrage pricing theory. Given the equivalence between the price of a coupon bond and the price of the corresponding swaptions, our approach can be adopted to calibrate the parameters of the two factor Hull White model using swaptions quoted in the market. The new solution we propose for the calibration can be considered as an alternative with respect to the existing approaches proposed in the literature and currently used by practitioners. Numerical results are provided in order to analyze the features of the proposed model for calibration purposes.
Decoction and Fermentation of Selected Medicinal Herbs Promote Hair Regrowth by Inducing Hair Follicle Growth in Conjunction with Wnts Signaling
Venue: Evidence based complementary and alternative medicine eCAM

It is well recognized that regulating the hair follicle cycle in association with Wnt signaling is one of the most interesting targets for promoting hair regrowth. In this study, we examined whether selected herbal medicines processed by decoction and fermentation promote hair growth by upregulating the number and size of hair follicles and Wnt signaling, including activation of b catenin and Akt in telogen synchronized C57BL/6N mice. The results revealed that the fermented extract after decoction (FDE) more effectively promoted hair growth than that of a nonfermented extract (DE) Notably, FDE effectively enhanced formation of hair follicles with clearer differentiation between the inner and outer root sheath, which is observed during the anagen phase. Mechanistic evidence was found for increased b catenin and Akt phosphorylation levels in dorsal skin tissue along with elevated expression of hair regrowth related genes, such as Wnt3/10a/10b, Lef1, and fibroblast growth factor 7. In conclusion, our findings suggest that FDE plays an important role in regulating the hair cycle by increasing expression of hair regrowth related genes and activating downstream Wnt signaling targets.
A review on the effect of rare earth elements on texture evolution during processing of magnesium alloys
Venue: Journal of Materials Science

Magnesium, the lightest structural metal, is approximately four times lighter than steel the most widely used metal in industrial applications. Currently available Mg alloys, however, are impractically expensive for use in automotive structural components, as severe ductility problems require forming operations at elevated temperatures and an exclusion from critical safety components. With a strong impetus in research having sprung up during the last two decades, addition of rare earth elements in small quantities emerged as a potential solution for simultaneously delivering the ductility and weight requirements for automotive applications. These improvements are arguably achieved by virtue of texture weakening and enhancement of non basal slip. However, ways by which rare earth elements modify texture remain very elusive, and no consensus on the driving mechanisms has been reached in the literature as of yet. We take a look back at different paradigms held for the action of rare earth additions, and examine key facts that may reconcile controversies. We attempt to identify critical gaps and suggest venues to overcome them. These gaps, once filled, may promote Mg alloys to become a stronghold for lightweighting, which will exceptionally benefit our environment and wellbeing.
Al Cu Li and Al Mg Li alloys: Phase composition, texture, and anisotropy of mechanical properties (Review)
Venue: Russian Metallurgy (Metally)

The results of studying the phase transformations, the texture formation, and the anisotropy of the mechanical properties in Al Cu Li and Al Mg Li alloys are generalized. A technique and equations are developed to calculate the amounts of the S1 (Al2MgLi) T1 (Al2CuLi) and d' (Al3Li) phases. The fraction of the d' phase in Al Cu Li alloys is shown to be significantly higher than in Al Mg Li alloys. Therefore, the role of the T1 phase in the hardening of Al Cu Li alloys is thought to be overestimated, especially in alloys with more than 1.5% Li. A new model is proposed to describe the hardening of Al Cu Li alloys upon aging, and the results obtained with this model agree well with the experimental data. A texture, which is analogous to that in aluminum alloys, is shown to form in sheets semiproducts made of Al Cu Li and Al Mg Li alloys. The more pronounced anisotropy of the properties of lithium containing aluminum alloys is caused by a significant fraction of the ordered coherent d' phase, the deformation mechanism in which differs radically from that in the solid solution.
Calibrating Noise to Sensitivity in Private Data Analysis
Venue: J. Priv. Confidentiality

We continue a line of research initiated in Dinur and Nissim (2003) Dwork and Nissim (2004) and Blum et al. (2005) on privacy preserving statistical databases. Consider a trusted server that holds a database of sensitive information. Given a query function $f$ mapping databases to reals, the so called \em true answer} is the result of applying $f$ to the database. To protect privacy, the true answer is perturbed by the addition of random noise generated according to a carefully chosen distribution, and this response, the true answer plus noise, is returned to the user. Previous work focused on the case of noisy sums, in which $f \sum_i g(x_i) where $x_i$ denotes the $i$th row of the database and $g$ maps database rows to [0,1] We extend the study to general functions $f$ proving that privacy can be preserved by calibrating the standard deviation of the noise according to the \em sensitivity} of the function $f$ Roughly speaking, this is the amount that any single argument to $f$ can change its output. The new analysis shows that for several particular applications substantially less noise is needed than was previously understood to be the case. The first step is a very clean definition of privacy now known as differential privacy and measure of its loss. We also provide a set of tools for designing and combining differentially private algorithms, permitting the construction of complex differentially private analytical tools from simple differentially private primitives. Finally, we obtain separation results showing the increased value of interactive statistical release mechanisms over non interactive ones.
