Learning While Helping: A Culture-Based Cooperative Learning Model for Vocational Education

Vocational education prioritizes learning outcomes in the form of skills, so that graduates are ready to work. The applied learning model must be carefully selected in order to produce optimal skills. This research tries to develop cooperative learning model of learning while helping type adopted from culture-based learning model. The learning model has been proven capable of producing many skilled workers in various fields, carpentry, agriculture, animal husbandry, or fisheries. The results of observations and interviews show that the learning process occurs informally during the cooperative process based on the principle of interdependence. The junior worker learns while helping a more senior worker. Senior workers also learn while helping supervisors. Thus the process takes place continuously. Once a junior worker becomes a senior worker and re-recruits junior workers. While senior workers become supervisors and accompany other senior workers. The learning model can be implemented in vocational schools by preparing workshops according to the skills they want to learn. Students learn from the lowest level of skills then gradually increase to the highest level of skill. The process of tiered coaching from senior to junior occurs continuously. Teachers act as supervisors and facilitators. This learning model more guarantees the alignment of process in the learning of skills, attitudes, and behavior, so that the competencies and character of the graduates are more integrated.

Extended Applications of Laser for Photothermal Treatment

Advances in nanobiotechnology have resulted in newer and improved diagnostic and treatment methods, including ultrasensitive molecular imaging, delivery of chemotherapeutic drugs, and photothermal treatment (PTT). We discuss characteristics and action mechanisms of PTT. Although the safety of nanoparticles has not yet been fully defined, in the future, PTT using nanotechnology may play an important role in treatment of malignant tumor.
Analysis of Efficiencies for Multiple-Input Multiple- Output Wireless Power Transfer Systems

Wireless power transfer (WPT) efficiencies for multiple-input multiple-output (MIMO) systems are formulated with a goal of achieving their maximums using Z matrices. The maximum efficiencies for any arbitrarily given configurations are obtained using optimum loads, which can be determined numerically through adequate optimization procedures in general. For some simpler special cases (single-input single-output, single-input multiple-output, and multiple-input single-output) of the MIMO systems, the efficiencies and optimum loads to maximize them can be obtained using closed-form expressions. These closed-form solutions give us more physical insight into the given WPT problem. These efficiencies are evaluated theoretically based on the presented formulation and also verified with comparisons with circuit- and EM-simulation results. They are shown to lead to a good agreement. This work may be useful for construction of the wireless Internet of Things, especially employed with energy autonomy.
Eutrophication problems and their potential solutions in the artificial shallow lake Altmuhlsee (Germany)

Lake Altmuhlsee in Middle Franconia, Germany, was constructed as part of a water transportation system and flooded in 1986 by River Altmuhl. Supply of nutrient rich water resulted in a hypertrophic state characterized by low Secchi depth (<0.5 m in summer). Massive blooms of phytoplankton in summer were mainly caused by cyanobacteria (Aphanizomenon flos-aquae, Anabaena flos-aquae, Microcystis aeruginosa) and by chlorophytes (Oocystis ssp., Monoraphidium ssp., Planktosphaeria gelatinosa), respectively. Fish assemblage was characterized by the dominance of planktivorous bream. Hence, zooplankton community mostly consisted of small-bodied cladocerans due to predation pressure by fish. Investigations of the phosphorus (P) cycle of Lake Altmuhlsee revealed high P-turnover rates in the water body and at the immediate sediment-water interface, an outstanding importance of external P-load, and a minor importance of the internal P-load. The lake supports recreational and social functions which, however, are restricted due to the low water quality. Improvement of water quality is necessary to increase attractiveness. Our study presents some proposals for an effective and economically justifiable water quality management, especially, biomanipulation in accordance to the holder of the fishing rights and local establishment of macrophytes.
Technology Readiness and Customer Satisfaction with Travel Technologies: A Cross-Country Investigation

Technologies have dramatically transformed tourist experience. However, research has largely focused on traveler attitudes and technology adoption rather than their experience with travel technologies. Taking a cross-country perspective, this study examines the role of technology readiness (TR) as a personality trait in shaping travelers’ satisfaction with travel technologies, using airlines as a case study. Results of an online survey of travelers in Australia, China, and the United States revealed the moderating effects of the TR dimensions of optimism and innovativeness as well as country of residence on the relationships between perceived quality of technology-enabled services (TESs), satisfaction with TESs, overall satisfaction, and future behavior. These relationships were stronger among travelers with higher TR and varied across countries. The results suggest that tourism and hospitality service providers should incorporate measures of traveler TR and TESs’ performance into their customer-experience monitoring system.
Mining User Groups in the Social News Website: Community Detection in Bipartite Networks.

Community clustering is well-studied in the context of social network analysis. However, in web services such as online retailing, music sharing library and social news website, the user data are more naturally modeled by the bipartite networks, where users are one class of the nodes and the product, song or story are the other. In this work, we propose a logistic weight model to transform the bipartite network to a weighted uni-partite network for clustering purpose. We experiment the model on Balatarin.com, a social news website and show the model leads to remarkably better clustering results by identifying and exploiting more informative users from the data.
Rescue of a non-viable accession and rapd analysis of recovered plants of Arachis retusa

In vitro regeneration of Arachis retusa was examined for the purpose of germplasm renewal and conservation. Random amplified polymorphic DNA (RAPD) fingerprinting was used to evaluate the genetic stability of plants derived from embryo axes and apical segments. Ten arbitrary decamer primers were screened and five of them were selected. Ninety genomic regions were evaluated, with an average of 18 loci per clone. All amplified segments were monomorphic. The results indicate that recovered plants are genetically stable at the assessed genomic regions and that both regeneration processes are suitable for in vitro germplasm preservation of Arachis species.
N-body dark matter haloes with simple hierarchical histories

We present a new algorithm which groups the subhaloes found in cosmological N-body simulations by structure finders such as SUBFIND into dark matter haloes whose formation histories are strictly hierarchical. One advantage of these `Dhaloes' over the commonly used friends-of-friends (FoF) haloes is that they retain their individual identity in the cases when FoF haloes are artificially merged by tenuous bridges of particles or by an overlap of their outer diffuse haloes. Dhaloes are thus well suited for modelling galaxy formation and their merger trees form the basis of the Durham semi-analytic galaxy formation model, GALFORM. Applying the Dhalo construction to the Λ cold dark matter Millennium II Simulation, we find that approximately 90 per cent of Dhaloes have a one-to-one, bijective match with a corresponding FoF halo. The remaining 10 per cent are typically secondary components of large FoF haloes. Although the mass functions of both types of haloes are similar, the mass of Dhaloes correlates much more tightly with the virial mass, M200, than FoF haloes. Approximately 80 per cent of FoF and bijective and non-bijective Dhaloes are relaxed according to standard criteria. For these relaxed haloes, all three types have similar concentration-M200 relations and, at fixed mass, the concentration distributions are described accurately by log-normal distributions.
Enhancing Education Quality Using Educational Data.

Educational data mining (EDM) is an interdisciplinary research area which is concerned with developing methods and techniques to explore big educational data. Due to the persistent growth and increasing availability of educational data, EDM facilitates data-driven decision making for enhancing learning and instruction. In the first place, this analytical study provides an introduction to EDM. Then, the researchers will look at various application areas of data mining in education, and lastly major challenges in mining big educational data are presented. The information provided in this paper enables educators to understand how big data helps them in improving the teaching and learning processes.
Would Consumers Value New Functional Properties of GM Food? A Choice-Modeling Approach for Rapeseed Oil

European consumers and, in particular, German consumers are known to be very critical towards the introduction of genetically modified (GM) foods. It is analyzed here whether German consumers do reject second-generation GMO foods, too. Whereas first-generation GM crops induced producer-related benefits, second-generation GM crops are associated with consumer-oriented benefits like an improvement of nutritional quality. The determinants of demand for second-generation GM rapeseed oil are investigated within an online survey of 1556 German consumers. It is elaborated how two functional properties of that product matter; i.e. long-chain omega 3 fatty acids and the cholesterol-lowering effect of phytosterols. It turns out that GMO rapeseed oil is neglected by 74% of all respondents. Output traits, however, will increase the probability of purchases of GMO rapeseed oil. This is more the case for long-chain omega 3 fatty acids than for phytosterols.
Measuring Urban Quality of Life Using Multivariate Geostatistical Models 1

Urban quality of life (QOL) is usually measured through an index de ned as the estimated value of a set of urban amenities. However there is an increasing awareness that omitted variables might seriously undermine the methods ability to accurately estimate QOL. Here we extend the hedonic approach using a multivariate geostatistical model to address the omitted variable bias by identifying the latent common factors responsible for the spatial distribution of the amenities. A new QOL index is then de ned as a function of the latent factors whose implicit prices are estimated through hedonic regressions. Our methodology is shown on a data set of individual-level property transactions from the city of Vicenza. As a result we obtain the spatial distribution of QOL calculated according to the new index.
Dative Sickness: A Phylogenetic Analysis of Argument Structure Evolution in Germanic (supplementary materials)

A major argument against the feasibility of reconstructing syntax for proto-stages is the widely discussed lack of directionality of syntactic change. In a recent typology of changes in argument structure constructions based on Germanic (Barðdal 2015), several different, yet opposing, changes are reported. These include, among others, processes sometimes called dative sickness, nominative sickness, and accusative sickness. In order to tease apart the roles of the different processes, we have carried out a phylogenetic trait analysis on a predefined data set of twelve predicates found across the Germanic phyla using the MULTISTATE method. This is, as far as we are aware, the first application of the MULTISTATE method (Pagel et al. 2004) in historical syntax. The results clearly favor one of the models, the dative sickness model, over any other model, as this model is the only one that can accurately account for both the observed diversity of case frames and the independently proposed philological reconstructions. Methods of evolutionary trait analysis can be used to model evolutionary paths of argument structure constructions, and they provide the perfect testing ground for hypotheses arrived at through philological reconstruction, based on classical historical-comparative methods. *
Optogenetics and its Applications in Psychology: Manipulating the Brain Using Light

In a broad sense, optogenetics uses genetically addressable photosensitive tools to monitor and control activity of living cells and tissue. This paper focuses on causal manipulation of neural populations by delivering light to light-sensitive ion channels or other proteins called microbial opsins. This enables refined manipulation of specific types or compartments of neurons with millisecond precision, whereas traditional electrical brain stimulation affects all neurons in a given area. Additionally, intracellular pathways can be studied using opto-XRs which could aid psychopharmacological research. Recent studies have applied optogenetics to psychology, leading to new experiments and yielding interesting results. Thus, this paper attempts to make optogenetics accessible to psychologists to enrich existing psychological research methods.
On Improvement in Construction Supply Chain Management

The aim of this paper is to provide a discussion on improvement in construction supply chain management. The study is based on a literature review regarding the evolution of supply chain management theory within the construction environment and a review of the current findings of supply chain management in industrial engineering. The paper presents five managerial practices to be studied and implemented in construction supply chain management. Such managerial practices are traditionally adopted by manufacturing companies and they reflect best practices for improvement in a multi-organizational environment. Even though this paper has a theoretical approach, it also aims to bring a contribution to practitioners by providing directions for improving construction supply chain management.
The Valuation Implications of Sales Growth in Start-up Ventures

We examine whether and how investors' reliance on financial information is affected by the rate of sales growth of a start-up venture. We find that investors discern between firms by the extent to which their products are adopted by the market. For firms that failed to increased their sales since IPO, investors preceive financial data as not providing relevant or predictive information for investment decision making. In contrast, investors seem to rely heavily on financial information provided by firms presenting a continuous increase in sales. We suggest that investors may perceive firms with a continuous increase (decrease) in sales as those that are (un)able to transfer through the technology adoption lifecycle and make the transition from an early market dominated by a few visionary customers to a mainstream market. Whereas prior studies relate changes in the value-relevance of financial statements to a firm's maturity, as measured on the basis of time (firm age), our findings indicate that the main factor affecting value-relevance is a firm's degree of market penetration.
On the characterisation and measurement of the welfare effects of income mobility from an ex-ante perspective

The paper employs a rank-dependent formulation of the social welfare function with time-separable utilities to evaluate the economic consequences of income mobility from an ex-ante perspective. The resultant class of measures can be decomposed not only in terms of structural and exchange mobility but also in terms of vertical and horizontal mobility, thereby encompassing two of the main approaches in the literature. We illustrate our measurement framework by comparing mobility in the USA and Germany using data from the Cross-National Equivalent File 1980-2005. We find that the pattern of income mobility in the USA was both less pro-poor and more horizontally inequitable than in Germany, but that the latter did not translate into higher levels of exchange mobility given higher levels of absolute inequality and the vertical stance of the growth process.
An ultrafast all-optical switch based on a nonlinear photonic crystal waveguide using single crystal p-toluene sulfonate

A novel design of an all-optical switch is proposed based on a nonlinear photonic crystal Mach–Zehnder interferometer (PC-MZI) to get the maximum switching speed and the minimum consuming power. As far as we know, this is the first study using a nonlinear polymer in one of the PC-MZI arms for realizing the switching phenomenon. All used components, such as bends, waveguides, and splitters, were individually optimized. Finite difference time domain and plane wave expansion methods were also utilized for the simulation of light propagation in the proposed structures.
The influence of low versus high fibre haylage diets in combination with training or pasture rest on equine gastric ulceration syndrome (EGUS)

The aim of this field study was to examine the influence of a low fibre (LF) and a high fibre (HF) diet on the presence of gastric ulceration in thirty 3-year old Dutch Warmblood horses during training period and during pasture rest. In the first part of the study all horses were stabled individually and fed either an iso-energetic HF (75% haylage) or LF (25% haylage) diet for sixteen weeks. Horses were exercised daily throughout this period, after which the first gastroscopy was performed. The second gastroscopy for all horses was performed following a fourteen week Pasture period during which grass was supplemented with haylage. Contrary to expectations the scores for number and severity of gastric lesions during the Training period were significantly higher in the HF group compared to the LF group. Additionally, horses of the HF group showed high haylage retention in the stomach after 12 hours fasting, whilst the LF group exhibited marked bedding eating and coprophagia. The results of gastroscopy following the Pasture period with extra haylage feeding for all horses, were similar to the HF horses following the Training period. These unexpected results may be related to the retention of the pre-fermented feed (haylage) in the stomach leading to continuing fermentation with increased volatile fatty acid (VFA) production in the stomach. The consumption of bedding and coprophagy shown by the LF group may have limited the previously reported high risk of gastric ulceration on a lowfibre diet.
Anthocyanin acyltransferase engineered for the synthesis of a novel polyacylated anthocyanin

Some polyacylated anthocyanins, anthocyanins containing two or more aromatic acyl groups, are blue in color within a wide range of pH values, including acidic and neutral conditions even in the absence of any co-pigments or metal ions. We engineered a mutant of a malonyl-CoA:anthocyanin 5-O-glucoside-6� -O-malonyltransferase of Salvia splendens (Ss5MaT1), Ss5AT306, which has an acquired specificity for hydroxycinnamoyl-CoA and is able to produce novel polyacylated anthocyanins. Ss5AT306 showed 6� -O-hydroxycinnamoyltransferase activity toward some anthocyanins in addition to the 6� -O-malonyltransferase activity retained (relative activities for acyl transfer to shisonin: malonyl-CoA, 100%; p-coumaroyl-CoA, 132%; caffeoyl-CoA, 103%). This alteration of acyl-donor specificity was achieved by the substitutions of only three contiguous amino acid residues, Val39-Arg40-Arg41, to the corresponding residues of anthocyanin aromatic acyltransferases, Met-Leu-Gln, suggesting that these amino acid residues are key residues governing the malonyl-CoA specificity of Ss5MaT1. Through the use of Ss5AT306, a novel polyacylated anthocyanin, p- coumaroylshisonin, with one aromatic acyl group in each of the 3-O-glucosyl and 5-O-glucosyl moieties of its structure, was produced and characterized in vitro. p-Coumaroylshisonin was bluer in color and displayed stronger color intensity than did shisonin, implying that accumulation of polyacylated anthocyanins such as p-coumaroylshisonin cause the modulation of flower colors.
Autonomy and Performance of Agentification: Cases of Nine Independent Agencies in Thailand ∗

Facing the limitations of bureaucracy and the pressures of crisis and change, the government reforms in many countries adopted a discipline of new public management (NPM) by separating autonomous agencies (agentification) in the public sector. Nonetheless, there are still very few empirical studies of performance assessment of this type of agency. This paper has two main objectives: (1) to explore the governance and autonomy of nine independent agencies under the Ministry of Industry (MOI) in Thailand; and (2) to present performance assessment of these nine independent agencies. This study uses both qualitative and quantitative approaches in collecting data, including three focus groups, 37 in-depth interviews, and 3,428 questionnaire surveys. The paper applies the concepts of agentification of NPM to examine the multidimensions of autonomy and to evaluate the performance of the nine agencies, covering effectiveness, financial self-reliance, and the impact on industrial development. Finally, this paper discusses the effects of agentification and suggests policy and managerial implications as well as further research directions.
O 3 and single-crystal phosphors for high-brightness white LEDs & LDs , and β-Ga 2 O 3 potential for next generation of power devices

β-Ga2O3 is the most transparent conductive oxide, well known since several decades for its large bandgap of 4.8 eV. Its potential as semiconductor material, however, is just emerging in recent years. Present work shows the development of β-Ga2O3 for semiconductor applications and its current state-of-the-art. The discussion is focused on three different aspects: (1) Advantageous growth from melt of large-size β-Ga2O3 single-crystals. High-crystalline quality and carrier control make possible the production of conductive and semi-insulating wafers. (2) β-Ga2O3 as substrate for homoepitaxy as well as for heteroepitaxial deposition of GaN-based devices. High-brightness blue-LEDs with vertical current injection are demonstrated. (3) Potential of β-Ga2O3 for highpower devices with higher breakdown voltage than GaN and SiC counterparts. The first Schottky barrier diode is shown, as well as first transistors (MESFET and MOSFET) are indicated. Single-crystal phosphors are introduced as novel alternative to currently used powder phosphors. In connection with high-brightness white light-sources, based on LEDs or LDs plus phosphor converters, single-crystal phosphors possess advantageous features. These avoid the use of resins and exhibit a very high internal quantum efficiency, which remains stable with the temperature increase.
