Societal values and local responses to appropriate livelihoods, fairness and decision-making involvement in ecotourism: Chiang Rai, Thailand

This paper examines local responses to ecotourism within the broader context of societal values. It acknowledges a strong contextual dimension to understanding those responses, and supports that with in-depth research on three villages in Chiang Rai in northern Thailand. The paper finds that land ownership is a central issue: those without land are those who consider alternative livelihoods to agriculture. Tourism, rather than a development option denied to under-privileged or unconnected members of society, appears to be a key development option for those without land. An uncontested view was expressed that benefits from tourism should be individually received by those involved rather by the community. Involvement in tourism decision-making was low and only desired by those directly involved, as a means of potentially increasing their personal incomes. For those stakeholders, involvement is dependent on village leaders and the representation that local tourism entrepreneurs and workers have through those leaders (based on shared ethnicity). These findings question an understanding within the tourism development literature that situates host communities as empowered through tourism, and adds to increasing criticism of aspects of community--based tourism.
O ct 2 01 2 TANAKA STRUCTURES MODELED ON EXTENDED POINCARÉ ALGEBRAS

Let (V, (·, ·)) be a pseudo-Euclidean vector space and S an irreducible Cl(V )-module. An extended translation algebra is a graded Lie algebra m = m−2 + m−1 = V + S with bracket given by ([s, t], v) = b(v · s, t) for some nondegenerate so(V )-invariant reflexive bilinear form b on S. An extended Poincaré structure on a manifold M is a regular distribution D of depth 2 whose Levi form Lx : Dx ∧Dx → TxM/Dx at any point x ∈ M is identifiable with the bracket [·, ·] : S ∧ S → V of a fixed extended translation algebra m. The classification of the standard maximally homogeneous manifolds with an extended Poincaré structure is given, in terms of Tanaka prolongations of extended translation algebras and of appropriate gradations of real simple Lie algebras.
Auctioned IPOs : The US evidence $ Francois Degeorge a , Francois Derrien

Between 1999 and 2007, WR Hambrecht completed 19 initial public offerings (IPOs) in the US using an auction mechanism. We analyze investor behavior and mechanism performance in these auctioned IPOs using detailed bidding data. The existence of some bids posted at high prices suggests that some investors (mostly retail) try to free-ride on the mechanism. But institutional demand in these auctions is very elastic, suggesting that institutional investors reveal information in the bidding process. Investor participation is largely predictable based on deal size, and demand is dominated by institutions. Flipping is at most as prevalent in auctions as in bookbuilt deals. But, unlike in bookbuilding, investors in auctions do not flip their shares more in ‘‘hot’’ deals. Finally, we find that institutional investors, who provide more information, are rewarded by obtaining a larger share of the deals that have higher 10-day underpricing. Our results therefore suggest that auctioned IPOs can be an effective alternative to traditional bookbuilding. & 2010 Elsevier B.V. All rights reserved.
Regularizing waveform inversion by projection onto intersections of convex sets

A framework is proposed for regularizing the waveform inversion problem by projections onto intersections of convex sets. Multiple pieces of prior information about the geology are represented by multiple convex sets, for example limits on the velocity or minimum smoothness conditions on the model. The data-misfit is then minimized, such that the estimated model is always in the intersection of the convex sets. Therefore, it is clear what properties the estimated model will have at each iteration. This approach does not require any quadratic penalties to be used and thus avoids the known problems and limitations of those types of penalties. It is shown that by formulating waveform inversion as a constrained problem, regularization ideas such as Tikhonov regularization and gradient filtering can be incorporated into one framework. The algorithm is generally applicable, in the sense that it works with any (differentiable) objective function, several gradient and quasi-Newton based solvers and does not require significant additional computation. The method is demonstrated on the inversion of very noisy synthetic data and vertical seismic profiling field data.

Polymer Membranes Sonocoated and Electrosprayed with Nano-Hydroxyapatite for Periodontal Tissues Regeneration

Diseases of periodontal tissues are a considerable clinical problem, connected with inflammatory processes and bone loss. The healing process often requires reconstruction of lost bone in the periodontal area. For that purpose, various membranes are used to prevent ingrowth of epithelium in the tissue defect and enhance bone regeneration. Currently-used membranes are mainly non-resorbable or are derived from animal tissues. Thus, there is an urgent need for non-animal-derived bioresorbable membranes with tuned resorption rates and porosity optimized for the circulation of body nutrients. We demonstrate membranes produced by the electrospinning of biodegradable polymers (PDLLA/PLGA) coated with nanohydroxyapatite (nHA). The nHA coating was made using two methods: sonocoating and electrospraying of nHA suspensions. In a simulated degradation study, for electrosprayed membranes, short-term calcium release was observed, followed by hydrolytic degradation. Sonocoating produced a well-adhering nHA layer with full coverage of the fibers. The layer slowed the polymer degradation and increased the membrane wettability. Due to gradual release of calcium ions the degradation-associated acidity of the polymer was neutralized. The sonocoated membranes exhibited good cellular metabolic activity responses against MG-63 and BJ cells. The collected results suggest their potential use in Guided Tissue Regeneration (GTR) and Guided Bone Regeneration (GBR) periodontal procedures.
SAUNDERS MAC LANE DESPITE PHYSICISTS, PROOF IS ESSENTIAL IN MATHEMATICS

Recently, the idea that mathematics essentially involves proofs (for lemmas, propositions and theorems) has come under attack from several directions. On the one hand, some of the various projects for the “reform” of education address high school geometry with the suggestion: Do not bother students with the proof of the Pythagorean theorem; just let them measure sides and hypotenuse of a few right triangles and so have them see that Pythagoras is correct. Similar proposals arise in the “reform” of the calculus; no mean value theorem and so no discussion of why and when Taylor series converge. These are samples of the occasional unhappy tendency of helping students by “dumbing down”. The Scientific American not long ago stirred up both its circulation and some opposition with an article entitled “The Death of Proof”. It carried a spurious argument for “Video proofs” and it was decorated with opinion from purported authorities. For example, William P. Thurston, a distinguished geometer, was cited, complete with his mistaken recollections of the role of proof in his earlier studies in logic; he has not bothered to correct these misstatements (They had been called to his attention). On a more substantial level, there have been many recent cases of the discovery and intuitive justification of important mathematical results long before complete proofs were at hand; one such is a deep result of Thurston asserting that suitable three dimensional manifolds (the Haken manifolds) can be cut up in pieces each of which has a good geometry (one given by a hyperbolic metric). Exciting new advances in theoretical physics make extensive use of mathematics, often producing mathematical results without proofs. Quantum Field Theory uses and extends deep results from differential geometry, tensor analysis and fiber bundles. The arcane topic of knot theory (find geometric invariants to tell the difference between a square knot and a granny knot) is illuminated by physics. String theory is for some physicists the hope for a successful theory of everything (TOE). There are many freewheeling (not always carefully proven) results in string theory. Some involve intuitive results by Richard Feynman – his diagrams for collisions and his (not yet justified) path integrals. A few year ago, Moore and Seiberg (1989) used the Feynman diagrams to find an intuitive geometrical proof
INVESTIGATION OF DROUGHT STRESS IN PEPINO (SOLANUM MURICATUM AIT. CV. MISKI) LEAVES

In this study, the effects of drought stress on pepino seedlings (Solanum muricatum cv. Miski) under natural greenhouse conditions were examined. The control plants were watered at field capacity, and the stress group was not watered. Samples were collected on the 6, 12, 24 and 36 days from the leaves of S. muricatum seedlings that, were exposed to drought stress. The relative water content, the total phenolic compounds, and the malondialdehyde, total photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids), and proline contents in these samples were determined. Depending on drought stress, the relative water content, the chlorophyll a, chlorophyll b and carotenoid contents, and the total chlorophylls were found to be lower in the stress group compared with the control group. In contrast, the total phenolic compounds (24 and 36 days) and the proline (12, 24 and 36 days) levels increased significantly compared with the control group. In addition, a significant increase in the malondialdehyde contents was obtained on the 36 day in the stress group compared with the control group. Such studies may be important for evaluation of metabolic changes in pepino under the drought stress.
Binary and Integer Coded Backtracking Search Optimization Algorithm for Transmission Network Expansion Planning

This paper proposes binary and integer coded of backtracking search (BS) technique for solving the Transmission Network Expansion Planning (TNEP) considering security constraints. TNEP is formulated as a mixed integer, non-linear, non-convex optimization problem. It aims to optimally select of the routs, types, and number of the added circuits to meet economically the expected future load forecasted while the operational and planning constrained are considered. The BS technique has various significant advantages of being simple structure, having single control parameter, and operating with two new tuned mutation and crossover which control the amplitude of the search-direction matrix and search space boundaries. The BS technique is applied to solve the TNEP problem on two Egyptian networks namely West Delta System (WDS) and 500 kV of Extra High Voltage System (EHVS) where the predicted load forecasting up to 2030 is based on the adaptive neurofuzzy inference system (ANFIS). The simulation results for the two realistic networks show the capability of the proposed technique to solve efficiently the TNEP problem and their superiority over the heuristic technique, the integer-based particle swarm optimization (IBPSO) technique and multi-verse optimizer (MVO) at acceptable economical and technical benefits. Key-Words: Transmission network, expansion planning, backtracking search technique, investment cost, binary coding, integer coding, security.
Adolescent Suicide- A Rising Trend

Objective: The study was aimed to assess knowledge, attitudes and practices of emergency contraception among the college students. Methodology: Data was collected through self administered questionnaires, where by students were instructed what to do in introductory remark. All this was done first before being administered in the class. Then the filled questionnaires were collected. Results: Majority were not using ECP 56(46.7%) with a reason of never had need for it, followed by 29 (24.2%) and 28 (23.3%), with reasons of partner doesn’t like it and religious reasons respectively. Cancer causation was chosen the least, 7 (5.8%). Only 23 individuals had ever used ECP in their life time, of these only 8 (34.8%) followed by 6 (26.1%) who had a failure in withdrawal. Only 136 individuals were able to respond to ECP using references, where by 75(55.1%) said yes. Large number of individuals 114 (85.7%) had never use ECP despite of sex exposure and only 19 (14.3%) were able to use ECP. Majority of individuals out of 80, 66 (82.55%) had a knowledge that ECP prevent pregnancy formation and few had a negative response, 7 (8.8%) causes abortion, 5 (6.3%) causes cancer. Conclusion: This study revealed that people in our country with much concern to bearing age group, have very little knowledge about emergency contraception. However, they are highly in need of getting it, and they are also in need of knowledge and dispensing units.
The implementation of the Objective Structured Practical Examination (OSPE) method: Students’ and examiners’ experiences

Background. Traditionally, physiotherapy practical skills have been assessed by a method that relies on the subjective interpretation of competency by the examiner and lacks the formative benefits of assessment. Objective. To describe and compare student performance and satisfaction and examiner satisfaction with regard to the Objective Structured Practical Examination (OSPE) and traditional mark sheets during the practical skills assessment. Method. Students and examiners taking part in the second-year physiotherapy practical skills test were invited to participate by completing a series of questionnaires. Performance of techniques was marked using both the OSPE and traditional mark sheets. Results. Sixty-seven students and nine examiners participated in the study. Students scored an average of 4.6% (SD ±16.4) better when using the traditional mark sheet. Nonetheless, students and examiners expressed a preference for the OSPE mark sheet. Conclusion. The OSPE mark sheet allows for increased objectivity, as the specific micro-skills are clearly listed and appropriately weighted. This resulted in increased satisfaction, but a decrease in marks obtained. By assessing the effect of implementation of the OSPE method on performance and satisfaction, change in the current situation can be monitored.
Improving time-critical, real-time, knowledge-based clinical decision support systems through usage data analytics

Knowledge-based decision support systems (KB-DSS) recommend decision actions based on stored knowledge. One of the challenges in time-critical clinical KB-DSS is the ability to maintain and continually improve the underlying knowledge-base. This challenge stems from the dynamic nature of the knowledge, and from the time constraints associated with the time critical interventions which do not afford for a traditional knowledge engineering approaches to feasibly occur during actual system usage. This paper explores the proposition that a usage-driven design approach could act as an enabler for the continual improvement of time critical, real-time KB DSS. We will describe a case study of an existing trauma reception and resuscitation time-critical real-time decision support system to express the challenges found in the current implementation and define the information requirements for supporting the proposed approach using a design-science-research methodology.
Does Lone Motherhood Indeed Decrease Women’s Subjective Well-Being?

This paper contributes to the discussion on the effects of single motherhood on happiness. We use a mixed-method approach. First, based on in-depth interviews with lone mothers who gave birth out of wedlock , we explore mechanisms through which children may influence mothers’ subjective well-being. In the second step we analyze panel survey data to quantify this influence. Our results leave no doubt that raising a child outside marriage poses many challenges, but at the same time parenthood has some positive influence on lone mother’s life. Our qualitative evidence shows that children are a central point in unmarried women’s life, and that many lifetime decisions are taken with consideration of the child’s welfare, including escaping from pathological relationships. Our quantitative evidence shows that although the general level of happiness among unmarried women is lower than among their married counterparts, raising a child does not have a detrimental effect on their subjective well-being.
"Vasopressin compared to norepinephrine in septic shock: Is vasopressin more effective?"

Klinzing and coworkers report on an experimental study of twelve septic shock patients. Patients ranged in age between 30 and 75 years-old; APACHE II scores on admission to the intensive care unit (ICU) were between 19 and 37, the underlying diagnosis varied among the patients, peritonitis being the most common, in 5 of the 12 patients. The diagnostic criteria for septic shock were taken according to the definitions of the American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference Committee. All studies were conducted under mechanical ventilation and under deep sedation. Radial arterial blood pressure, central venous pressure and cardiac output were measured in all patients. Blood samples for blood gas determination of oxygen tension, pH, lactate concentration, hemoglobin and oxy“Vasopressin compared to norepinephrine in septic shock: Is vasopressin more effective? ”
(CZTSSe) Solar Cells

Current benchmark thin film solar cell (TFSC) technologies based on polycrystalline CuInxGa1−xS(Se)2 (CIGS) and CdTe absorber materials have reached record efficiencies of 20.8 and 19.6 % for laboratory-scale devices and have already reached the commercial production stage [1]. However, these thin film photovoltaic (PV) technologies suffer from serious issues of toxicity, skyrocketing material cost, and/or low abundance of raw materials, which are predicted to severely limit the production, mass deployment, and economic sustainability of these solar cells [2–9]. Indium (In), gallium (Ga), and tellurium (Te) supply have been categorized as “critical” by the US Department of Energy (DOE) and the European Commission (EC) [10, 11]. Particularly, In supply for CIGS production could be stringent as more than 80 % of In produced worldwide is consumed by the flat panel display (FPD) industry and with ever-increasing demand of such displays, sustainability and economic viability of CIGS PV technology could be in great danger in upcoming years [12]. Also, due to the environmental health concerns, use of toxic cadmium (Cd) hinders the mass production and deployment of CdTe solar cells [13]. Thus, an intense research effort has been triggered to develop alternative thin film solar absorber materials comprising of earth-abundant, low-cost, and non-toxic elements which can yield high-efficiency devices, be economically
www.econstor.eu Level-k Mechanism Design

Models of choice where agents see others as less sophisticated than themselves have significantly different, sometimes more accurate, predictions in games than does Nash equilibrium. When it comes to mechanism design, however, they turn out to have surprisingly similar implications. This paper provides tight necessary and sufficient conditions for implementation with bounded depth of reasoning, discussing the role and implications of different behavioral anchors. The central condition slightly strenghthens standard incentive constraints, and we term it strict-if-responsive Bayesian incentive compatibility (SIRBIC). JEL Classification: C72, D70, D78, D82.
SPINACH POWDER ADDITION TO SUCUK FOR ALTERNATIVE TO NITRITE ADDITION

The effect of spinach powder addition on lipid oxidation, color and sensorial characteristics of traditional fermented meat product (Sucuk) was studied. Sucuk was manufactured with three treatments (control, 1% spinach powder added, 3% spinach powder added) and two replicates. Sucuks fermented by spontaneous fermentation. The pH of the spinach powder added samples were significantly (p<0.01) lower than the control group. L*and a* values of the control group was significantly (p<0.01) higher than treament groups but b* values of 3% spinach powder added group was significantly (p<0.01) higher than the others. TBA values of the treatment groups were significantly (p<0.051) lower than the control group during the beginning of the fermentation period. On the third day, TBA value of the control group was low, on the 7th and 14th days TBA values of the treatment groups were found to be significantly lower. There was no significant difference was found between the sucuk samples at the end of the storage. When the sensory properties were analyzed, the color, taste, texture and general acceptability values of spinach powder added sucuk samples scores were found to be significantly (p<0.01) lower than the control group.
Preparation and Characterization of Chemical Bath Deposition synthesis CdS Nanocrystalline Thin Films

Cadmium sulfide (CdS) nanocrystalline thin films are prepared onto ITO-glass and Si(111) substrates by chemical bath deposition method. The scanning electron microscope images showed that the CdS thin film onto Si substrate is more homogenous without vacancies. The XRD patterns of the CdS nanocrystalline thin film confirm that they have polycrystalline with cubic phase. Room temperature photoluminescence (PL) spectrum of the CdS nanocrystalline thin films shows emission band located at 502nm for CdS/Si sample while the CdS/ITO-glass thin films shows a broad emission band peaked at 505nm. The Raman spectra of CdS nanocrystalline thin films prepared onto Si and ITO-glass substrates contain two main peaks which are corresponding to the first and second-order longitudinal optical (LO) phonon modes.
Simulation of Heat Transfer on Blood Flow through a Stenosed Bifurcated Artery

Article history: Received 21 April 2019 Received in revised form 13 June 2019 Accepted 25 July 2019 Available online 31 August 2019 Atherosclerotic with high occurrence of plaque happened due to stenosis that caused narrowing of the vessel wall causing an alternation in the flow structure. Previous researchers have proved that the formation of stenosis with high probability of rupture can be characterized by the changing of the temperature distribution in the bifurcated artery. The aim of the study is to investigate the dynamic response of heat transfer in blood flow through bifurcated artery under stenotic condition. The blood vessel is modelled as a two-dimensional (2D) rigid wall and the blood flow is assumed to be Newtonian fluid, incompressible, laminar, and steady. Simulation result is obtained by using COMSOL Multiphysics 5.2, a software based on the FEM. The investigation is focused on the blood flow characteristics such as the velocity profile, temperature profile and streamline pattern of which has been discussed and fundamentally agreed well with the available literature. The outcome shows that the presence of stenosis with slightly change of the stenosis shape and value of Reynold number give appreciable influences to the velocity, temperature distribution and reverse flow recirculation as indicated by negative flow near the arterial wall.
