Reallocation and Productivity during Commodity Cycles

I study the firm-level dynamic response of a commodity-exporting economy to global cycles in commodity prices. To do so, I develop a heterogeneous-firms model that endogenizes declines in aggregate productivity through reallocation towards less productive firms. Within a given sector, commodity booms reallocate market share away from exporters because of currency appreciation and away from capital-intensive firms because of the increase in capital cost. I provide empirical evidence for these channels using microdata for Chile, the world’s largest copper producer. When fed with the commodity super-cycle of 2003-2012, the calibrated model generates about 50% of the observed productivity decline.
Molecular Dynamics Simulation of Phase Change in Heptadecane-Pentadecane Binary System

The melt behavior of heptadecane,pentadecane and heptadecane-pentadecane mixed system are stu-died by molecular dynamics simulation and NTP ensemble. The phase transition temperature of these systems is determined according to the sharp changes of self-diffusion coefficient and specific volume against temperature,respectively. The simulation temperature value is agreed well with experiment value provided by references. The phase transition temperature of different constitution of binary system is determined. The phase transition temperature of binary system can be varied with the constitution to fit into some special energy-saving conditions. In melting process the change of microscopic structure of heptadecane molecular is studied by analyzing dihedral angel. It is shown that order degree of heptadecane molecular will decrease with the increase of temperature in melting process.
Revision of “Dependence of Climate States of Gray Atmosphere on Solar Constant: From the Runaway Greenhouse to the Snowball States” by Ishiwatari et al. (2007)

Ishiwatari et al. (2007) (https://doi.org/10.1029/2006JD007368) investigated multiple equilibrium solutions of a gray atmosphere for various values of solar constant, utilizing two types of models, namely, a one‐dimensional energy balance model and a general circulation model (GCM) with simplified physical processes, both of which permit existence of the runaway greenhouse state. The study was retracted, since there was a bug in their GCM that affected quantitative aspects of the study. Here, we revise the study with re‐performing all of the GCM experiments using an appropriately corrected model. The results of re‐experiments show that the main features of the climate regime diagram drawn in the solar constant ‐ ice line latitude plane are mostly unchanged, except that the ice‐free equilibrium state, which existed in Ishiwatari et al. (2007) (https://doi.org/10.1029/2006JD007368) now disappears. It is confirmed that there are the partially ice‐covered state, the globally ice‐covered state, and the runaway greenhouse state. These three states coexist for intermediate values of solar constant. The existence of the large ice cap instability is also confirmed, although the critical latitude of the partially ice‐covered state extends equatorward. Also same as before, the small ice cap instability does not seem to appear.
Effects of Baby Massage in Reducing Body Temperature after Combined Diptheri Pertussis Tetanus/Hepatitis B Immunization

Background: Side effects that may often occur after immunization include fever in infants after to combined Diptheri Pertusis Tetanus/Hepatitis B (DPT/HB) vaccine. Fever in infants or toddlers is a case that cannot be ignored because it can interfere with the comfort and development of infants and toddlers. Objectives: This research aims to analyze the effects of baby massage in lowering body temperature among babies given combined DPT/HB immunization. Material and Methods: It is a quasi-experiment using one intervention group. The population and sample are babies aged 2-5 months visiting the Work Area of Puskesmas Lombok Barat in Indonesia that meet inclusion criteria. Baby massage was administered in the morning and in the afternoon for 5 days, with the first 2 days prior to combined DPT/HB immunization 1, the second 1 day at the time of immunization, and the last 2 days after immunization. The same treatment was also carried out for combined DPT/HB immunization 2. Prior and after massage, baby temperatures were measured at the axila using a digital thermometer, with the results put in an observation sheet (graph). Body temperature measurement was observed for 2 months. Data gathered were then tested using non-parametric test (Wilcoxon). Results: there is reduction in body temperature among babies given combined DPT/HB immunization 1 and combined DPT/HB immunization 2. Babies given combined DPT/HB immunization 1 had average body temperature of 0,2±0.18 °C in the morning and 0,21±0.25 °C in the afternoon. Meanwhile, babies given combined DPT/HB immunization 2 had average body temperature of 0,26±0.19 °C in the morning and 0,2±0.23 °C in the afternoon. Effect of massage in reducing body temperature among babies given combined DPT/HB immunization 1 is at (p<0.005) and at (p<0.005) for combined DPT/HB immunization 2. Conclusion: massage can be performed before or after babies are immunized with combined DPT/HB to lower their body temperature.
Artificial Data Management in Reaching Conditional Cash Transfer of Program Keluarga Harapan (PKH) Utilizing Simple Addictive Weighting

The main challenge in implementing a poverty reduction program is to identify precisely the targets that will benefit a program. Program Keluarga Harapan (PKH) is a social protection program from the central government through the provision of conditional cash transfers to Low-Income Households (RTSM)/Low-Income Families (CBOs), which are designated as Program Keluarga Harapan beneficiary families. Program Keluarga Harapan is the conditional cash transfer (CCT) program to reduce poverty by making welfare programs dependent upon the receivers’ actions. The accuracy of choosing targets directly impacts the achievement of social protection programs’ objectives in poverty alleviation. This research would like to dig up how Jogjakarta’s government is accurate to reach the beneficial Program Keluarga Harapan recipient. In terms of Jogjakarta’s government using the support system to classify the low-income family as the receiver of conditional cash transfers. Therefore, this research will explain which decision-making model used by the government of Jogjakarta managed by a computerized system, known that computerized data processing is expected to present information rapidly, precise, clear, and directed as the exact target for the program.
The Extent of Honeycombing on Computed Tomography Cannot Predict the Treatment Outcome of Patients with Acute Exacerbations of Interstitial Lung Disease

Background The purpose of this retrospective study was to clarify whether the presence of honeycombing on computed tomography (CT) can affect the prognosis of patients with acute exacerbations (AEs) of interstitial lung diseases (ILDs). Methods Clinical parameters including age, sex, Charlson Comorbidity Index Score (CCIS), blood biomarkers, and 3-month mortality were retrospectively compared between the CT honeycombing present and absent groups at the diagnosis of AEs of ILDs. Results Ninety-five patients who were on corticosteroid pulse therapy were assessed. Though log-rank tests showed that Kaplan–Meier survival curves of the high and low ground-glass opacity (GGO) score groups differed significantly in 3-month mortality in patients with AEs of idiopathic ILDs (P = 0.007) and overall patients (P = 0.045), there was no significant difference between the CT honeycombing present and absent groups in patients with AEs of idiopathic ILDs (P = 0.472) and AEs of secondary ILDs (P = 0.905), as well as of overall patients (P = 0.600). In addition, whereas CCIS (OR, 1.436; 95% CI, 1.156–1.842; P < 0.001) was a significant predictor of 3-month mortality in the CT honeycombing absent group, serum LDH (OR, 1.005; 95% CI, 1.002–1.007; P = 0.001) was a significant predictor in the CT honeycombing present group. Conclusions The clinical features of patients with or without honeycombing may differ due to the difference in prognostic factors, but these groups were found to have similar prognoses 3 months after AE onset, and clinicopathological examinations according to these groups are essential.
Universal Filter Design Using 45 nm FinFET Technology-Based Floating Current Source

ABSTRACT Fin type Field Effect Transistor (FinFET) technology is a promising technology for single-digit nanometric dimensions. FinFETs are used to increase the performance by reducing the power consumption as the two gate voltages are controlled dependent and/or independently. This work explores the design of a Floating Current Source (FCS) using Double Gate (DG) FinFET and its application of a universal filter. The designed FinFET based FCS operates at 0.15 V power supply, the power consumption of the circuit is 51nW and bandwidth is approximately 100 MHz. The proposed FCS based filter circuit is simulated in LTspice with the FinFET 45 nm PTM-MG model. The filter topology behavior has been tested with an experimental study using the LM13700 integrated circuit and the experimental results are demonstrated. The proposed FinFET based circuit and its application can be used for the design of systems that require low power consumption and low chip area.
Decomposition of straight chain hydrocarbon volatile organic compounds with gliding arc discharge

n-butane(n-C4H10) and n-hexane(n-C6H14) were chosen as the target volatile organic compounds(VOCs) to investigate the influences of supply voltage and background atmosphere on the decomposition rate and by-products of the straight chain hydrocarbon VOCs decomposition with gliding arc discharge,and the mechanism was also studied.Results show that the increase of supply voltage can improve the decomposition efficiency by increasing the energetic electrons density;the main decomposition by-products in the nitrogen atmosphere are C1~C4 hydrocarbons such as CH4 and C2H2,in contrast,CO,CO2,H2O and NO2 are the predominant decomposition products when the air is chosen as the carrier gas;radical mechanism plays a key role in the decomposition process,and the increase of background oxygen concentration promotes the decompositions of both n-butane and n-hexane;increasing the oxygen concentration can advance the formation of CO2,CO and NO2 and promote the conversion of CO to CO2.
Defining Integrated Weed Management: A Novel Conceptual Framework for Models

Weed population dynamics models are an important tool for predicting the outcome of alternative Integrated Weed Management (IWM) scenarios. The growing problem of herbicide resistance has increased the urgency for these tools in the design of sustainable IWM solutions. We developed a conceptual framework for defining IWM as a standardised input template to allow output from different models to be compared and to design IWM scenarios. The framework could also be used as a quantitative metric to determine whether more diverse systems are more sustainable and less vulnerable to herbicide resistance using empirical data. Using the logic of object-oriented programming, we defined four classes of weed management options based on the stage in the weed life cycle that they impact and processes that mediate their effects. Objects in the same class share a common set of properties that determine their behaviour in weed population dynamics models. Any weed control “event” in a system is associated with an object, meaning alternative management scenarios can be built by systematically adding events to a model either to compare existing systems or design novel approaches. Our framework is designed to be generic, allowing IWM systems from different cropping systems and countries to be compared.
Testing the Effect of Asynchronous Discussions in a Language and Content-Integrated Hybrid Course

The method of teaching delivery has been found to have significant impact on students’ learning. “Hybrid” or “blended” courses that mix face-to-face and online instructional methods have gained popularity in education, including in the field of language learning and teaching. There is an increasing number of studies that have explored the methodology of constructing a hybrid class for English language teaching and its potential benefits for student learning. However, little has been studied with regard to using a hybrid course where English and content subjects are integrated. The purpose of the research described in this chapter was to test the effect of asynchronous discussions on learning outcomes of students within a hybrid course and to compare the effectiveness of the course with a more traditional one. In both types of courses, American economic history and English language were learnt simultaneously. A regression model was used to analyze the quantitative data obtained from investigating both types of course formats. The study finds that the incorporation of online discussion forums into an English and content-integrated course can help improve student academic performance.
The effect of task technology fit and entrepreneurship education on student’s entrepreneurship intention using the theory of planned behaviour

Entrepreneurship has been proven in various researches in the world to help improve the welfare of society by creating jobs. Many universities in the world have adopted entrepreneurship in their curriculum designs in the form of entrepreneurship education. Besides, the technology fit task variable is also important in increasing student entrepreneurship intention. Therefore, research on entrepreneurship intention (EI) and the factors that influence it among students is very relevant. This study aims to fill the knowledge gap in the effect of task technology fit (TTF) and entrepreneurship education (EE) on entrepreneurship intention (EI) by using the theory of planned behavior (TPB) model. The research sample was 213 undergraduate students at one of the private universities in Yogyakarta selected by the Slovin method. Data were collected through a questionnaire shared with the student by MS Form. Regression analysis tools were used to test the research hypothesis. These results prove that H1, H3a, and H3b have a positive effect on EI with different levels of significance. Meanwhile, H2 has a negative influence on EI. This study has contributed to filling the knowledge gap that TTF and EE can be integrated into the TPB model.
Detection of subsurface cracks using inductive thermography

Inductive thermography is a well-established NDT method to detect surface cracks in metallic materials. The induced eddy current density decays exponentially below the surface, penetrating up to the so-called skin-depth. This depth depends on the excitation frequency and on material parameters, as the magnetic permeability. As a surface crack is an obstacle for the eddy current and for the heat flow, it becomes visible in the infrared images. It is investigated whether cracks ending below the surface, can be detected by inductive thermography. It is stated, that when the crack end is lying closer the surface than the half skin-depth, then it can be detected. This statement is investigated for ferro-magnetic and non-magnetic samples and for different excitation frequencies. The inspection is usually done in reflection mode, but for thin wall work-pieces the transmission mode provides a good detection possibility. Experimental results are compared with finite element simulation results.
Can compassion to the self be extended to others: the association of self-compassion and other-focused concern

ABSTRACT Although self-compassion has consistently been shown to be effective in the promotion of well-being, its effects in the promotion of compassion to others has been limited. The present study examined the causal effect of self-compassion on other-focused concern through three studies. Study 1 and Study 2 showed that a one-week practice of self-compassion was effective in the promotion of self-compassion. However, compassion to others was significantly decreased in both self-compassion and control conditions in Study 1 and it did not significantly increase in Study 2. With a didactic element added in Study 3, the cultivation of self-compassion, compassion to others, and both, significantly promoted both self- and other-compassion. However, results also indicated the stronger effects of cultivation of other-compassion or cultivation of both self- and other-compassion on other-focused concern than the cultivation of self-compassion alone and highlighted the importance of didactic element in the cultivation of self-compassion on other-focused concern.
Water Safety Plan for Securing Drinking Water Supply from River Bank Filtration Projects in Egypt – A case Study.

The main objective of water utilities is securing the supply of safe drinking water with adequate quantity to safeguard public health. The Water Safety Plan (WSP) is considered an efficient way to ensure water safety according to the latest published information from the World health organization (WHO). WSP is dependent on a proactive approach to reduce the opportunity of hazards from the water source to the consumers' taps. In this study, an application of the concepts was done to secure the drinking water produced from River Bank Filtration (RBF). Both managerial and technical potential reason for risk was studied and the appropriate corrective action was settled. In general, it was found that however, RBF is considered a well-established water technology with a low cost it still could be vulnerable to different kinds of potential hazards. The study has shown potential risks in the source, RBF, network, and customer community. In RBF, the water resource area is the more sensitive to the potential hazard with risk score reach up to 20 on a scale of 1 to 25. The average risk factor before the implementation of the corrective actions is about 10 which classified as high risk. These corrective actions include short-term with low cost that could be considered as quick-win actions other long-term actions have also been identified. The application of this action will ensure a decrease in the average risk to 3 (low risk). The corporate stakeholders and their liabilities have been identified and a group of (Key performance indicators) KPIs was developed for the process to be manageable. (Non-Governmental Organizations) NGOs have a major role in the application of corrective actions such as facilitating the connection for the poor citizen. The involvement of NGOs in the water management process at Abu Bisht will allow direct interaction between the industry and community which overall will increase the social responsibility of the company and at the same time increase the valuation of water at the mentality of the customers.

Rigorous treatment of the 
S1/Z2
 orbifold model with brane-Higgs couplings

We build rigorously the attractive five-dimensional model where bulk fermions propagate along the $ \mathcal{S}^1 / \mathbb{Z}_2$ orbifold and interact with a Higgs boson localised at a fixed point of the extra dimension. The analytical calculation of the fermion mass spectrum and effective Yukawa couplings is shown to require the introduction of either Essential Boundary Conditions (EBC) imposed by the model definition or certain Bilinear Brane Terms (BBT) in the action, instead of the usual brane-Higgs regularisations. The obtained fermion profiles along the extra dimension turn out to undergo some discontinuities, in particular at the Higgs brane, which can be mathematically consistent if the action is well written with improper integrals. We also show that the $\mathbb{Z}_2$ parity transformations in the bulk do not affect the fermion chiralities, masses and couplings, in contrast with the EBC and BBT, but when extended to the fixed points, they can generate the chiral nature of the theory and even select the Standard Model chirality set-up while fixing as well the fermion masses and couplings. Thanks to the strict analysis developed, the duality with the interval model is scrutinised.
