School Mental Health Programme for Teachers Recruited Through Corporate Social Responsibility : A Quasi Experimental Study

School Mental Health Programmes (SMHP), are being conducted for school teachers in Bangalore. Corporate Social Responsibility (CSR) is playing a pivotal role in providing educational services. However teachers in these programmes are not adequately trained to identify the mental health issues related to children. The aim was to study the usefulness of a brief SMHP for school teachers working as part of a CSR project in Bangalore. Twenty two school teachers of a CSR project participated in a brief SMHP. The program aimed at orienting the teachers’ in common mental issues of children. Data was collected using a semi structured self reported interview schedule before and after the intervention which included 5 domains such as developmental, learning, behavioural, anxiety and severe mental disorders. The median age of the respondents was 26 years. Majority of them were females (N=18), unmarried (N=14), of an urban background (N=15) of Bangalore. There was a significant improvement in post assessment scores on all the domains compared to baseline indicating the improved knowledge of the teachers. Participants in this SMHP gained increased knowledge on children’s mental health issues and managing them at school level. However, further systematic studies with larger sample are required to generalize the findings.
Association between Total Diet Cost and Diet Quality Is Limited

There is a common perception that it costs more to eat a healthy diet than a less healthy one. We derive a panel data model that accounts for unobserved specific individual effects to estimate the relationship between diet quality and total daily food expenditure. Since total daily diet cost and diet quality are both calculated from the foods chosen in our data, we account for the fact that there is an endogenous relationship between diet quality and cost. We find that while total daily food expenditure is statistically significant in relation to diet quality, the degree of association is very small.
Population dynamics has greater effects than climate change on tree species distribution in a temperate forest region

Population dynamics and disturbances have often been simplified or ignored when predicting regional‐scale tree species distributions in response to climate change in current climate‐distribution models (e.g., niche and biophysical process models). We determined the relative importance of population dynamics, tree harvest, climate change, and their interaction in affecting tree species distribution changes.
Effect of varying ratios of n-6 and n-3 on selenium content in broiler breast muscle

Abstract To investigate the effect of fatty acid composition on broiler meat selenium concentration and antioxidative capacity, 60 broiler chickens were individually fed one out of three high-selenium diets, based on either soybean oil (SO), rapeseed oil (RO) or a RO/linseed oil (LNO) mix. Breast muscle total selenium concentration was significant decreased (P=0.007) in the SO compared to RO and LNO dietary groups, while no differences were observed for antiradical power, glutathione peroxidise values or sensory evaluation for the three groups. LNO resulted in an almost five times lower ratio between arachidonic acid and eicosapentaenoic acid and a three times lower n-6/n-3 ratio compared to the SO group. These results indicate that dietary fatty acid composition may affect broiler meat total selenium concentration and suggest that a lowered n-6/n-3 ratio and increased level of n-3 polyunsaturated fatty acids in broiler meat may increase total selenium in meat.
Mayoral Partisanship and the Size of Municipal Government

Does it matter for municipal policy which party controls the mayorship in municipal government? The bulk of the existing evidence says no. But there are a variety of theoretical reasons to believe that mayoral partisanship should a↵ect municipal policy. We examine the impact of mayoral partisanship in nearly 1000 elections in medium and large cities over the past 60 years. In contrast to previous work, we find that mayoral partisanship has a significant impact on the size of municipal government. Democratic mayors spend substantially more than Republican mayors. In order to pay for this spending, Democratic mayors issue substantially more debt than Republican ones and pay more in interest. Our findings show that mayoral partisanship matters for city policy. Moreover, our findings add to a growing literature indicating that the constraints imposed on city policymaking do not prevent public opinion and elections from having a meaningful impact on municipal policy. We appreciate the research assistance of Melissa Meek, Olivia Zhao, Dylan DiGiacomo-Stumm, and Szabolcs Kiss. We appreciate feedback on earlier versions of this manuscript from Chris Tausanovitch, Dan Hopkins, Katherine Einstein, David Glick, and Melissa Sands. We also appreciate the willingness of Fernando Ferreira, Joseph Gyourko, Elisabeth Gerber, and Dan Hopkins to share their data. All mistakes, however, are our own. ⇤PhD Candidate, Department of Political Science, MIT, jdbk@mit.edu †Assistant Professor, Department of Political Science, MIT, cwarshaw@mit.edu
Photosynthesis, Nitrogen Metabolism and Antioxidant Defense System in B-Deficient tea (Camellia sinensis (L.) O. Kuntze) Plants

Response of tea plants to B deficiency was studied in hydroponic medium under environmentally controlled conditions. Plants height, number of leaves and dry matter production of shoot and root were significantly decreased by B deficiency. Concentration of chlorophyll, carotenoids, anthocyanins and flavonoids was not affected by B deficiency in the young leaf, while a significant reduction of Chl a/b ratio and increase of carotenoids concentration was detected in the old leaf. Among leaf chlorophyll fluorescence parameters, only nonphotochemical quenching ( qN ) increased in parallel to increase of carotenoids in the old leaves of B-deficient plants. Net assimilation ( A) and transpiration ( E) rate and stomatal conductance ( gs) were decreased significantly under B deficiency conditions only in the young leaf. Activity of nitrate reductase increased in the young and decreased in the old leaf slightly, but was not influenced by B deficiency in the roots. Nitrate concentration diminished while nitrite concentration increased in the young leaf under B starvation. Data of antioxidant enzymes activity implied that ascorbate peroxidase was likely important for the protection of old leaf and peroxidase for roots, while superoxide dismutade contributed to the protection of all three organs against oxidative stress provoked by B deficiency conditions. H 2O2 content of leaves and roots did not increase or even decreased under B deficiency conditions, that was associated with accumulation of proline. Our evidences suggest a protective role for proline against free radicals that may contribute significantly to the higher tolerance of tea plants to B deficiency.
Quantum atomic lithography via cross-cavity optical Stern-Gerlach setup

We present a fully quantum scheme to perform two-dimensional atomic lithography based on a cross-cavity optical Stern–Gerlach setup: an array of two mutually orthogonal cavities crossed by an atomic beam perpendicular to their optical axes, which is made to interact with two identical modes. After deriving an analytical solution for the atomic momentum distribution, we introduce a protocol allowing us to control the atomic deflection by manipulating the amplitudes and phases of the cavity field states. Our quantum scheme provides subwavelength resolution in the nanometer scale for the microwave regime.
Connecting Student Teachers during Their Internship: The Role of ICTs

Practical training is an important aspect of teacher education programs in Quebec (Canada) universities. Student teachers spend one hundred and twenty days of their four-year university program interning in high schools in order to progressively develop their professional skills within their chosen field. The present study proposes to enhance understanding of the potential advantages of information and communication technologies (ICTs) in practical teacher training (field practice). More specifically, it aims to shed light upon how ICTs help student teachers overcome teaching challenges encountered during field practice. Results presented are taken from a pilot study conducted during the internship of 800 student teachers from the province of Quebec (Canada).
Automated Representations of Temporal Aspects of Elec-troacoustic Music: Recent Experiments Using Perceptual Models

Within this paper we firstly examine the determination of a number of temporal aspects of Electroacoustic Music, and their representations. Then various automated segmentation methods, for Harrison’s Unsound Objects, are investigated. We find the multi-granular approach outlined by Lartillot et al., combined with the use of MFCCs, is a very efficient and salient segmentation strategy for music structured predominantly according to timbre. Further, the ‘Contrast’ parameter is both versatile and effective in determining the granularity of segmentation.
ON THE EFFECTIVENESS OF TASK GRANULARITY FOR TRANSFER LEARNING

We describe a DNN for video classification and captioning, trained end-to-end, with shared features, to solve tasks at different levels of granularity, exploring the link between granularity in a source task and the quality of learned features for transfer learning. For solving the new task domain in transfer learning, we freeze the trained encoder and fine-tune a neural net on the target domain. We train on the Something-Something dataset with over 220, 000 videos, and multiple levels of target granularity, including 50 action groups, 174 fine-grained action categories and captions. Classification and captioning with Something-Something are challenging because of the subtle differences between actions, applied to thousands of different object classes, and the diversity of captions penned by crowd actors. Our model performs better than existing classification baselines for SomethingSomething, with impressive fine-grained results. And it yields a strong baseline on the new Something-Something captioning task. Experiments reveal that training with more fine-grained tasks tends to produce better features for transfer learning.
Toward EEG-based BCI driven by emotions for addressing BCI-Illiteracy : a meta-analytic review

Many critical aspects affect the correct operation of a Brain Computer Interface. The term “BCIilliteracy” describes the impossibility of using a BCI paradigm. At present, a universal solution does not exist and seeking innovative protocols to drive a BCI is mandatory. This work presents a meta-analytic review on recent advances in emotions recognition with the perspective of using emotions as voluntary, stimulus-independent, commands for BCIs. 60 papers, based on electroencephalography measurements, were selected to evaluate what emotions have been most recognized and what brain regions were activated by them. It was found that happiness, sadness, anger and calm were the most recognized emotions. Most discriminant locations for emotions recognition and for the particular case of discrete emotions recognition were identified in the temporal, frontal and parietal areas. The meta-analysis was mainly performed on stimulus-elicited emotions, due to the limited amount of literature about self-induced emotions. The obtained results represent a good starting point for the development of BCI driven by emotions and allow to: 1) ascertain that emotions are measurable and recognizable one from another 2) select a subset of most recognizable emotions and the corresponding active brain regions.
Return dynamics during periods of high speculation in a thinly traded commodity market

This article studies the effects of speculation in a thinly-traded commodity futures market paying particular attention to periods characterized by high speculative activity of long-short speculators. Using the speculation ratio as a daily measure for long-short speculation, we employ GARCH-regressions to study its impact on return dynamics. Our results for the CME feeder cattle futures market suggest that future returns are predominantly explained by fundamentals, but their volatility is significantly driven by the speculation ratio. This relationship holds for periods of high and low speculative activity alike.
FINITE ELEMENT ANALYSIS OF THE PSEUDO-ELASTIC BEHAVIOR OF SHAPE MEMORY ALLOY TRUSS AND BEAM

The pseudo-elastic behavior of Shape memory alloy (SMA) truss and cantilever beam are investigated. Brinson’s one-dimensional material model, which uses the twinned and detwinned martensite fractions separately as internal variables, is applied in the algorithm to establish the SMA stress-strain characteristics. This material model also incorporates different young’s modulus for austenitic and martensite phase to represent the true SMA characteristics. In this model, a cosine function was used to express the evolution of the stress induced martensite fractions during the forward and reverse martensite phase transformation. A finite element formulation for the SMA truss member considering the geometric nonlinearity is proposed and the results are compared with the corresponding linear analysis. As a step forward, a finite element formulation for an SMA cantilever beam with an applied end moment is proposed. The load displacement characteristic for both the loading and unloading phases are considered to check the full pseudo-elastic hysteretic loop. In the numerical investigation, the stress-strain variation along the beam depth is also examined during the loading and unloading process to investigate the forward and reverse martensite phase transformation phenomena. Newton-Raphson’s iterative method is applied to get convergence to the equilibrium for each loading steps. During a complete loading-unloading process, the temperature is kept constant as the model is essentially an isothermal model. Numerical simulation is performed considering two different temperatures to demonstrate the effect of temperature on the hysteretic loop.
CROSS CULTURAL STUDY OF CUSTOMER SATISFACTION WITH SELF SERVICE TECHNOLOGY IN RETAIL SETTINGS OF INDIA AND INDONESIA

While the world’s largest developing markets like Brazil, Russia, India, China, Malaysia— still tempt the largest global retailers and show no signs of slowing down, many smaller, untapped markets are providing new profit frontiers, particularly for regional and specialty players. Undoubtedly India has also been one of the top favorite destinations for the foreign retailers and with the Government approving foreign direct investment in retail all the big retail giants like Wal-Mart, Tesco are eyeing the diverse culture of India that is going to offer them a huge opportunity. For Indonesia, attractive middle class, an expanding middle class, steadily growing economy (roughly 6 percent per year), and declining debt-to-GDP ratios are enticing the global retailers. Even though the share of organized retail is only 4% its total retail sales in 2012 had been USD 322 billion on the other hand Indonesia having 30% share of organized retail had total retail sales of USD 150 billion. Keeping up the pace with global retailing, technology is also gaining its share of importance in the organized retail sector as technology is transforming the way retailers operate in developing markets. But at the same time the question arises are Indians and Indonesians ready to shop smartly or they would still prefer to stand in long ques every weekends to pay their bills or redeem their membership cards? Since both the countries are backed by strong cultural dimensions like collectivism, masculinity and uncertainty avoidance, it is important to understand whether the consumers are really prepared to believe in their self efficacy and accept technology innovations to enhance their shopping experience or they still want to be dependent on the front line service employees. Considering the fact that these dimensions are very important in a globalised economy and potential adaptation of new technology based service models is crucial for successful market entry, this research paper attempts to find out how the consumers perception regarding acceptance of Self Service Technology is influenced by the cultural dimensions of both the nations.
The effectiveness of exercise on function for adults with shoulder impingement syndrome (sis): a structured literature review.

Objective: To examine the effects of exercise on the function of adults with shoulder impingement syndrome (SIS). Design: A structured literature review of randomized controlled trials (RCTs). Methods: Studies were identified from databases searched from 2007 to April 2016 MEDLINE, EMBASE, PEDro, Sports Discus, AMED and Cochrane Library, only one reviewer selected studies meeting inclusion criteria. The methodological quality of the included studies was independently assessed by the same reviewer using the PEDro quality assessment tool. Results: Eight studies were included in the review and appraised for content. Five studies achieved a score of 6 or above indicating good quality, tree trials were rated as moderate quality. No study achieved lower <4 to indicate poor quality. Conclusion: Due to the lack of a detailed description of the exercise protocols used, the current evidence is difficult to interpret in relation to use in clinical practice. Therefore, future RCTs studying exercise therapy should also concentrate on the effect of different exercise protocols, including the intensity, duration, frequency and load of the exercises.
Gene diversity and organization in rbcL-containing genome fragments from uncultivated Synechococcus in the Gulf of Mexico

Factors controlling phytoplankton distribution and activity in the marine environment are often poorly understood. Knowledge of genomic content and organization may aid in understand- ing these processes. To this end, bulk environmental DNA was extracted from Gulf of Mexico sea- water and cloned into a bacterial artificial chromosome (BAC) vector to generate a library of 3000 large-insert clones. This library was probed for various types of RubisCO gene (rbcL); 8 rbcL- containing clones (20 to 73 kb in size) were detected and sequenced. rbcL sequences indicated that they originated from marine α-Synechococcus spp. Genomic organization was highly similar to that of the sequenced genome of Synechococcus sp. strain WH 8102 in the region surrounding rbcL. Sev- eral differences from known α-Synechococcus were also observed, including putative monoamine oxidase and amino acid transport genes, and electron transport, photosynthesis and hypothetical protein genes similar to those of Prochlorococcus spp. (i.e. flavodoxin, thioredoxin reductase and iron-stress-induced chlorophyll-binding proteins). These findings indicate that the order and composition of the carbon fixation operon (cbbX to ccmK) is highly conserved in α-Synechococcus, while adjacent genomic composition indicates expanded metabolic capabilities obtained from gene- transfer events with Prochlorococcus spp. and other cyanobacteria.
Application of LabVIEW and Genetic Algorithm for controlling of Plate Heat Exchanger

The mathematical modeling of plate heat exchanger (PHE) was studied by effect several step change in entrance hot fluid stream and measuring the temperature of exit cold fluid. Based on the energy balance, a mathematical model for this heat exchanger (PHE) transmit factor (U) is linked with the warm fluid stream (mh). To confirm this model, the control on temperature was applied experimentally and theoretically to the plate heat exchanger using P, PI and PID controllers with some different tuning methods of control parameters; genetic alg - To assess the achievement of control, the time domain specifications such as rise time, overshoot (OS), settling time, measures of control system efficiency (integrates the square of the error over time (ISE) and integrates the absolutes error over time (IAE)) are used. The PID controller gave better control of temperature than other controllers, While Ziegler – Nichols method gave better control than Cohen-Coon. Genetic Algorithm (GA) technique is the best method in simulation compared with Cohen-Coon and Ziegler – Nichols methods because of the semi-perfect regulation of adjusted parameter values that give lower oscillatory pattern, minimal sum error, but it gives the slower response to reach the steady state.
Transport and reaction of nanoliter samples in a microfluidic reactor using electro-osmotic flow

The primary focus of the paper is to establish both numerical and experimental methods to control the concentration of samples in a microreactor well. The concentration of the reacting samples is controlled by varying the initial sample size and electric field. Further, the paper numerically investigates the feasibility of mixing and reacting nanoliter samples with a wide variation in reaction rates in the microreactor driven by electro-osmotic pumping. Two discrete samples are measured and transported to the microreactor simultaneously by electro-osmotic pinching and switching. The transported samples are mixed in the microreactor and floated for 4.5 s for reaction to occur. It is seen that the normalized concentration of the product increases from 0.25 to 0.45 during that period. Also the effects of sample size and applied electric field on sample concentration during the switching process are studied. It is found that the normalized final sample concentration increases from 0.03 to 0.11 with an increase in sample size from 60 to 150 µm, at a constant electric field. Further, by increasing the electric field from 100 to 1000 V cm−1, at a constant sample size, there is a significant decrease in the final concentration of the sample from 0.14 to 0.04. Our studies also show that the normalized product concentration depends on the reaction rate and increases from 0.28 to 0.48 as the reaction rate increases from 10 L mol−1 s−1 to 105 L mol−1 s−1. However, the increase in the reaction rate beyond 105 L mol−1 s−1 does not influence the product concentration for the present design of the microreactor. Our microreactor with improved mixing can be used for assessing reactions of biological samples. The optimized sample size along with a controlled electric field for sample injection forms the basis for developing a prototype of a microreactor device for high throughput drug screening.
Single paternity within broods of the brown crab Cancer pagurus: a highly fecund species with long-term sperm storage

Declining population sizes reported for a number of marine species have emphasised the need for information on mating systems to be incorporated into conservation and management strategies, particularly for exploited species. The brown crab Cancer pagurus L. supports a major fishery; however, many aspects of the species' mating system, such as paternity patterns, are unre- solved. In this study, 3 microsatellite loci conferring a high degree of statistical power were used to determine whether broods from 18 ovigerous females collected from the English Channel had been fertilised by multiple males. Despite the capacity of this species for long-term storage of sperm and the suspected potential for females to use sperm from multiple males simultaneously, no evidence of multiple paternity was detected. Hypotheses as to the predominant processes leading to single pater- nity are discussed. In systems where females exhibit genetic monogamy the effective population size is constrained by the number of females. Such systems may be particularly susceptible to declines if females are removed. This has important implications for management of C. pagurus populations, as fishery data indicate that females are more heavily harvested than males.
