Innate and Learned Responses of the Tephritid Parasitoid Psyttalia concolor (Hymenoptera: Braconidae) to Olive Volatiles Induced by Bactrocera oleae (Diptera: Tephritidae) Infestation.
Venue: Journal of economic entomology

Parasitic wasps can learn cues that alter their behavioral responses and increase their fitness, such as those that improve host location efficiency. Psyttalia concolor (Szepligeti) (Hymenoptera: Braconidae) is a koinobiont endoparasitoid of 14 economically important tephritid species, including the olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae) In this research, we investigated the nature of olfactory cues mediating this tritrophic interaction. First, we identified the chemical stimuli emanating from uninfested and B. oleae infested olive fruits via solid phase microextraction and gas chromatography mass spectrometry analyses and identified >70 volatile organic compounds (VOCs) Two of these were increased by B. oleae infestation, (E) b ocimene and 2 methyl 6 methylene 1,7 octadien 3 one, and four were decreased, a pinene, b pine ne, limonene, and b elemene. Innate positive chemotaxis of mated P. concolor females toward these VOCs was then tested in olfactometer assays. Females were attracted only by (E) b ocimene, at both tested dosages, indicating an intrinsic response to this compound as a short range attractant. Next, we tested whether mated P. concolor females could learn to respond to innately unattractive VOCs if they were first presented with a food reward. Two nonassociative controls were conducted, i.e. "odor only" and "reward only." Following training, females showed positive chemotaxis toward these VOCs in all tested combinations, with the exception of limonene, a VOC commonly produced by flowers. Control females showed no significant preferences, indicating that positive associative learning had occurred. These results clarify how learned cues can fine tune innate responses to B. oleae induced VOCs in this generalist parasitoid of tephritid flies.
Service Recovery via Social Media

Social media channels are increasingly used by consumers to post complaints to companies. In contrast to traditional channels, the complaint and a firm's recovery efforts are visible to passive observers who are virtually present. Additionally, these unaffected users may become involved by supporting a complainant with negative comments or by supporting the firm with positive comments, leading to interactive virtual presence (VP) We reveal that such VP affects how a complainant reacts to successful and unsuccessful service recovery. Based on social influence theory (SIT) we investigate the influence of a mere VP as well as interactive VP of positive and negative valence on the complainant's satisfaction and purchase intentions and analyze the role of expertise of those who are virtually present. The results indicate that SIT is applicable to virtual environments but that restrictions apply. Specifically, mere VP enhances the effects of recovery success, but in contrast to SIT not the negative results of unsuccessful recovery, and interactive VP leads to attitude polarization. Moreover, high expertise individuals who engage in positive (negative) interactions after unsuccessful (successful) recovery are deleterious. When experts disconfirm successful recovery, they have higher credibility and reduce confidence in the firm. However, in contrast to SIT, experts trying to mitigate unsuccessful recovery are perceived as less credible, which also reduces confidence. Overall, if service recovery via social media is successful, firms will benefit from VP. However, caution is advised when using expert users who may interfere with service recovery processes.

A significant part of this Review explores the possibilities of graphene/graphene oxide based 3D superstructures and their use in lithium ion batteries. This Review ends with a look at challenges and future prospects of noncovalently modified graphene and graphene oxide.
Electrochemically Exfoliated Graphene and Graphene Oxide for Energy Storage and Electrochemistry Applications.
Venue: Chemistry

Top down methods are of key importance for large scale graphene and graphene oxide preparation. Electrochemical exfoliation of graphite has lately gained much interest because of the simplicity of execution, the short process time, and the good quality of graphene that can be obtained. Here, we test three different electrolytes, that is, H2 SO4 Na2 SO4 and LiClO4 with a common exfoliation procedure to evaluate the difference in structural and chemical properties that result for the graphene. The properties are analyzed by means of scanning transmission electron microscopy (STEM) Raman spectroscopy, and X ray photoelectron spectroscopy. We then tested the graphene materials for electrochemical applications, measuring the heterogeneous electron transfer (HET) rates with a Fe(CN)6 (3 /4 redox probe, and their capacitive behavior in alkaline solutions. We correlate the electrochemical features with the presence of structural defects and oxygen functionalities on the graphene materials. In particular, the use of LiClO4 during the electrochemical exfoliation of graphite allowed the formation of highly oxidized graphene with a C/O ratio close to 4.0 and represents a possible avenue for the mass production of graphene oxide as valid alternative to the current laborious and dangerous chemical procedures, which also have limited scalability.
The role of media in tourism promotion: A case study in Ethiopia

Media has a pervasive power for good or bad. Ethiopia suffers a lot from negative media presentations, even though the country hosts many glamorous features. And also its tangible and intangible tourist attractions can serve as a tool to change the images of the country in the international community. The country has more than Twelve UNISCO registered world heritages and more natural and cultural endowments, yet it benefits less from them. This work attempts to assess the tourism potential of the country and its actual gain from the sector. Moreover, it focuses on what role the media has to play in the process. To put this into effect, mixed methodology has been used and the result showed that, there exists a great gap between the potential that the country has and its benefit from it. The bridge is widened by lack of promotion through the different media outlets. The qualitative methodology was helpful to analyze contents related to the new media outlets while quantitative one addresses the views of one hundred tourists who have the experience of visiting the country. Hence the result revealed that the country has not been benefited from its potential. Key words Tourism, Promotion, Image, Destination, Media.
The Lost and the New 'Liberal World' of Welfare Capitalism: A Critical Assessment of Gosta Esping Andersen's The Three Worlds of Welfare Capitalism a Quarter Century Later
Venue: Social Policy and Society

Celebrating the 25th birthday of Gosta Esping Andersen's seminal book The Three Worlds of Welfare Capitalism (1990) this article looks back at the old 'liberal world' and examines the new. In so doing, it contributes to debates and the literature on liberal welfare state development in three main ways. First, it considers the concept of 'liberalism' and liberal ideas about welfare provision contained within Three Worlds. Here we are also interested in how liberal thought has conceptualised the (welfare) state, and the class mobilisation theory of welfare state development. Second, the article elaborates on 'neo 'liberal social reforms and current welfare arrangements in the English speaking democracies and their welfare states. Finally, it considers the extent to which the English speaking world of welfare capitalism is still meaningfully 'liberal' and coherent today.
Learned helplessness at fifty: Insights from neuroscience.
Venue: Psychological review

Learned helplessness, the failure to escape shock induced by uncontrollable aversive events, was discovered half a century ago. Seligman and Maier (1967) theorized that animals learned that outcomes were independent of their responses that nothing they did mattered and that this learning undermined trying to escape. The mechanism of learned helplessness is now very well charted biologically, and the original theory got it backward. Passivity in response to shock is not learned. It is the default, unlearned response to prolonged aversive events and it is mediated by the serotonergic activity of the dorsal raphe nucleus, which in turn inhibits escape. This passivity can be overcome by learning control, with the activity of the medial prefrontal cortex, which subserves the detection of control leading to the automatic inhibition of the dorsal raphe nucleus. So animals learn that they can control aversive events, but the passive failure to learn to escape is an unlearned reaction to prolonged aversive stimulation. In addition, alterations of the ventromedial prefrontal cortex dorsal raphe pathway can come to subserve the expectation of control. We speculate that default passivity and the compensating detection and expectation of control may have substantial implications for how to treat depression.
Mechanisms of the Water Gas Shift Reaction Catalyzed by Ruthenium Carbonyl Complexes.
Venue: The journal of physical chemistry. A

Density functional theory (DFT) is employed to study the water gas shift (WGS) reaction in the gas phase for two complexes, Ru3(CO)12 and Ru(CO)5. Here we report four mechanisms of ruthenium carbonyl complexes catalyzed for WGS reaction. The energetic span model is applied to evaluate efficiency of the four catalytic pathways. Our results indicate that mechanism C and D show a good catalytic behavior, which is in agreement with results from the literature. The mechanism C and D not only include the important intermediate Ru3(CO)11H( but also exclude the energy demanding OH( desorption and revise an unfavorable factor of the previous mechanism. Two complexes along mechanisms B have the highest turnover frequency (TOF) values. The trinuclear carbonyl complexes Ru3(CO)12 is preferred over mononuclear carbonyl Ru(CO)5 by comparing TOF due to the fact that metal metal cooperativity can enhance activity to the WGS reaction. In this work, the nature of interaction between transition states and intermediates is also analyzed by the detailed electronic densities of states, and we further clarify high catalytic activity of ruthenium carbonyl complexes as well. Our conclusions provide a guide to design catalysts for the WGS reaction.
Carbon Dioxide Transformation in Imidazolium Salts: Hydroaminomethylation Catalyzed by Ru Complexes.
Venue: ChemSusChem

The catalytic species generated by dissolving Ru3 (CO)12 in the ionic liquids 1 n butyl 3 methyl imidazolium chloride or 1 n butyl 2,3 dimethyl imidazolium chloride are efficient multifunctional catalysts for: (a) reverse water gas shift, (b) hydroformylation of alkenes, and (c) reductive amination of aldehydes. Thus the reaction of alkenes with primary or secondary amines (alkene/amine, 1:1) under CO2 /H2 (1:1) affords the hydroaminomethylations products in high alkene conversions (up to 99 and selectivities (up to 96 The reaction proceeds under relatively mild reaction conditions (120 degC, 60 bar=6 MPa) and affords selectively secondary and tertiary amines. The presence of amine strongly reduces the alkene hydrogenation competitive pathway usually observed in the hydroformylation of terminal alkenes by Ru complexes. The catalytic system is also highly active for the reductive amination of aldehydes and ketones yielding amines in high yields >90
A delay bound efficient path design algorithm for mobile sink in wireless sensor networks
Venue: 2016 3rd International Conference on Recent Advances in Information Technology (RAIT)

Hotspot problem is one of the major hindrance in the long run functioning of the wireless sensor network. Sink mobility has strongly emerged as a potential solution to it. Here, mobile sink visits the proximity of sensor nodes to collect data from them. However, this results into a lengthy path which is undesirable in most of the applications bounded by some delay. In our work, we propose a rendezvous point(RP) based delay bound path design for the mobile sink. In the proposed method, the target area is partitioned into hexagonal cells whose centers are considered as the potential positions of RPs. These potential positions are minimized on the basis of several network parameters to select minimum number of RPs to form the delay bound path. Extensive simulations were carried over the proposed algorithm to compare its results with some existing algorithm using several performance metrics like hop count, network lifetime and many more to prove its effectiveness.
Solving Unidirectional Flow Path Design Problems Using Metaheuristics

Metaheuristics are widely used to solve a lot of problems for production systems. The aim of this study is to solve the flow path design problem with different metaheuristics especially developed for this particular problem. Flow path design consists of the determination of the direction of each segment and the paths that will be used by vehicles in production units. The organization of these routes directly influences the performance of the system. For example, the time of transport and the number of vehicles necessary depends on this organization. That is why this problem is one of the most important issues in AGV (automated guided vehicles) system design. This work deals with flow path design problem for a conventional unidirectional network, which is a general network where segments can be taken by vehicles in only one direction. For this specific problem, efficient optimization methods based on local search (MLS, ILS) Bee Algorithm (BA) and Ant Colony Optimization (ACO) are developed in order to solve the flow path design problem to minimize the total travel distance considering both loaded and empty trips. The problem will be described, the resolution methods will be detailed and their performances proven.
Perception of symmetry and asymmetry in individuals with anterior cruciate ligament reconstruction.
Venue: Clinical biomechanics

Changes in the quantity, quality and integration of sensory information are thought to persist long after anterior cruciate ligament reconstruction and completion of physical therapy. Our purpose was to investigate the ability of individuals with anterior cruciate ligament reconstruction to perceive imposed asymmetry and symmetry while walking.  Twenty participants with anterior cruciate ligament reconstruction and 20 controls walked on a split belt treadmill while we assessed the ability to detect symmetry and asymmetry at fast and slow speeds. Detection scores and spatiotemporal data during asymmetric and symmetric tasks in which the belts were coupled or decoupled over time were recorded.  The ability to detect symmetry and asymmetry was not altered in individuals with anterior cruciate ligament reconstruction compared to healthy young adults. The belt speed ratio at detection also correlated to asymmetry for step length, stride length, double support time, and stance time. However, the anterior cruciate ligament reconstruction group appeared to utilize unique information to determine detection. When asked to detect symmetry at a fast speed, no asymmetry scores significantly correlated with belt speed ratio in the anterior cruciate ligament reconstruction group. Conversely, asymmetry in stride length, step length, and stance time all significantly correlated with belt speed ratio at detection in the control group.  Specific sensory cues arising from the speed of the leg may also augment perception of symmetry. This strategy may be necessary in order to successfully execute the motor task, and could develop due to altered sensory information from the reconstructed knee at faster walking speeds.
Acceptance and Disclosure: Comparing genetic symmetry and genetic asymmetry in heterosexual couples between egg recipients and embryo recipients
Venue: Facts, views vision in ObGyn

This paper explores the attitudes and experiences of 203 women in heterosexual couples who conceived via donated eggs (145) or donated embryos (58) in the last 5 years. Online surveys were sent to former patients (from many different countries) of a private Spanish clinic. By comparing the women in heterosexual couples who relied on donated eggs with those who relied on donated embryos, we examined the meaning of the absence of a genetic tie to a child in the two different situations that of "genetic symmetry" where neither parent has a genetic tie to that of "genetic asymmetry" where only the mother does not have a genetic tie. No existing study has yet shown whether women who rely on donated eggs and women who rely on donated embryos have similar or different attitudes towards issues surrounding the experience of non genetic motherhood. Three issues are discussed: (1) attitudes toward the importance of genetic ties and genetic information from the donor before and after the birth of their children, (2) patterns of disclosure, and (3) the relationship between attitudes toward genetic information and disclosure decisions. This study showed that although the two groups of women have many of the same attitudes, including attitudes toward the importance of genes as determinants of outcomes for the child, egg recipients are more likely than embryo recipients to agree that the genetic origins are important to them and that their children have a right to know genetic information. We also found that those who conceived with donated eggs more frequently disclose the nature of their conception to their child than do those who conceived with donated embryos.
Problems and needs in helping older people with dementia with daily activities: Perspectives of Thai caregivers

Caring for people with dementia can be stressful and demanding. The purpose of this qualitative descriptive study was to investigate the problems and needs of caregivers who help older people with dementia to do activities of daily living.  Thirty caregivers who took older people with dementia to get treatment at a memory clinic in a hospital in the north of Thailand were interviewed using a semistructured interview. Transcribed data were analysed using inductive analysis.  The analysis generated five themes related to problems experienced by caregivers: toileting is the hardest job, lifting causes back pain, loss of memory problems, economic hardships and psychological distress. These issues aggregated into support needs from three sources: information and rehabilitation services from health professionals, assistance with everyday tasks from family members and financial support from society.  The findings reveal that the kind of support Thai caregivers seek from various groups differs according to their perceived expertise and availability. Further studies are needed to explore how that assistance might be delivered and whether it is in fact helpful.
Push and spin: A complete multi robot path planning algorithm
Venue: 2016 14th International Conference on Control, Automation, Robotics and Vision (ICARCV)

In multi robot path planning problem domain, robots must move from their start locations to their goal locations avoiding collisions with each other. There are various cooperative algorithms in this domain with their specialized strengths. Notable amongst them are Push and Swap (PAS) Push and Rotate (PAR) which appear as most favorable for such problems. This can be attributed to the reason that they don't impose as many restrictions on the graph topology. Our analysis, however, shows that a wider class of solvable instances is excluded from PAS and PAR domain. In this paper, we have proposed Push and Spin (PASp) algorithm, as a new complete cooperative algorithm for Multi robot Path Planning problem with rotation (MPPr) for any instance recognized by the solvability test as solvable without any assumption. The algorithm employed two operations i.e. a "push" operation where robots move towards their goals up to the point that no progress can be made, and "spin" operation that allows two robots to swap positions without altering the configuration of other robots. The experimental results show that the PASp performs competitively in terms of number of moves compared to PAS, PAR and tractable multi robot path planning (MAPP) algorithms, on a set of benchmark problems from the video game industry, in reasonable execution time. In addition, results show the scalability and robustness of PASp in problems that can be solved only by PASp. Such problems require high levels of coordination with an efficient number of moves, in short execution time. In bi connected graphs, with too many cycles, PASp produces a higher number of moves than PAS, PAR and Bibox algorithms in a higher time. However, PASp is the only one capable of solving such instances with only one empty vertex.
[Endocrine disruptors: A missing link in the pandemy of type 2 diabetes and obesity?
Venue: Presse medicale

The prevalence of metabolic syndrome, obesity and type 2 diabetes has dramatically increased worldwide during the last few decades and exceeds World Health Organisation's predictions. Lifestyle factors such as decreased physical activity and energy dense diet, together with a genetic predisposition, are well known actors in the pathophysiology of these metabolic diseases. However, there is accumulating evidence suggesting that the increased presence of endocrine disrupting chemicals (EDCs) in the environment, may also explain an important part in the incidence of metabolic syndrome, obesity and type 2 diabetes. EDCs are found in everyday products (including food, plastic bottles, metal cans, toys, cosmetics, pesticides. and used in the manufacture of food. They interfere with the synthesis, secretion, transport, activity and/or elimination of natural hormones. Those interferences can block or mimic hormone actions and thus induce a wide range of adverse effects (especially reproductive effects and hormone dependent cancers) In rodents, acute exposure to bisphenol A is responsible for modifications of insulin synthesis and secretion in pancreatic beta cells but also for modifications of insulin signalling in liver, skeletal muscle and adipose tissue, which both lead to insulin resistance, a major condition in pathophysiology of metabolic syndrome, obesity and type 2 diabetes. In humans, some epidemiologic reports suggested a strong link between exposure to some persistant EDCs (as organochlorine pesticides, dioxins and polychlorinated biphenyl ethers) and type 2 diabetes and obesity, especially after acute and accidental releases of EDCs (Seveso plant explosion, Vietnam war veterans) Other cross sectional studies among the world reported suggestive to strong association between diabetes and obesity and EDCs exposure, especially for persistant organic pollutants, which should now be considered as insulin resistance risk factors.
