Human Capital, Economic Growth, and Public Expenditure

To understand the weak empirical relationship between human capital and macroeconomic performance, we present a model in which human capital is allocated to three activities: production, tax collection (bureaucracy), and public education. The effective tax rate is low in poor countries because tax collection requires human capital, which is scarce. Throughout the transition, the effective tax rate rises, which involves a diversion of human capital from production to bureaucracy and public education. Consequently, human capital has a weak effect on production, even when human capital is efficiently allocated. Differences in institutional quality may involve a spurious negative correlation between gross domestic product and human capital.
Build and Improve Business Processes for Evaluation Consulting

This chapter considers some business processes that evaluation consultants may integrate into their practices to increase success. An opportunistic sample of consultants was interviewed to understand the business processes they employed and what data if any, they gathered to assess and to inform adjustments in them. This chapter discusses processes that surfaced in the interviews, including the technology the consultants use to monitor projects, the templates they develop for automation, and the procedures they use to organize teams and projects. The chapter also demonstrates how consultants can use business process management to take a holistic view, analyze and reflect on data, and decide on plans for improvement. An example illustrates the process mapping to study business processes. Two other examples illustrate how evaluation consultants transform business processes. One addresses a need to improve efficiency; the other is about strategic planning customized to the frameworks of evaluative thinking and complexity thinking. By developing and transforming processes, evaluation consultants can apply an evaluative lens to their business and make plans to increase success.
Energy-Constraint Formation for Multiagent Systems With Switching Interaction Topologies

The current paper investigates energy-constraint formation design and analysis problems for multiagent systems with two types of switching interaction topologies; that is, leaderless ones and leader-following ones. Firstly, a new formation control protocol with switching interaction topologies is shown, where the whole energy supply is limited previously. Then, by constructing the relationship of the whole energy supply and the matrix variable, sufficient conditions for leaderless energy-constraint formation design and analysis are respectively presented by the linear matrix inequality tool. Furthermore, an approach is proposed to determine an explicit expression of the formation center function, which determines the macroscopic motion of a multiagent system as a whole and consists of two parts: the initial state term and the formation function term. Moreover, main conclusions of leaderless energy-constraint formation are extended into leader-following multiagent systems by a new two-step transformation approach, where the asymmetric structure feature of leader-following switching interaction topologies is well dealt with. Finally, two numerical examples are provided to demonstrate the effectiveness of main conclusions.
College Students’ Knowledge and Perceptions of Tourism Climate Change Impacts: Do Major, Grade and Gender Matter?

ABSTRACT The purpose of this study was to examine the level of understanding and perceptions of climate change using the variables of major, gender, and class level with a sample of undergraduate college students. Using a Likert-type questionnaire, data were collected from a randomly selected sample in a Midwest college in the United States. The study found that students in the tourism major were similar in their understanding and perceptions of climate change when compared to non-tourism majors. Males and females differed in their overall climate change knowledge and perceptions regarding climate change. In addition, class level (year 1–4) had a significant impact on students’ climate change perceptions and understanding of climate change knowledge. These and other findings from the study have important implications for tourism education and curriculum development relative to climate change issues, particularly at the post-secondary and college levels.
Extracranial Carotid and Vertebral Artery Ultrasonography: Resistive Indices for Diagnosing Cerebral Brain Death

Introduction —Transcranial Doppler (TCD) has been used to document blood flow indicative of patients who are clinically brain dead. Limitations of TCD include signal loss in the absence of an adequate acoustic window, or extensive craniotomies that interfere with TCD insonation. Additionally, when compared with duplex ultrasonography of extracranial carotid and vertebral arteries, TCD is more technically difficult to master, with limited availability in many institutions. Objective —We sought to evaluate the use of carotid and vertebral artery ultrasound resistive indices in patients with clinically diagnosed brain death. Methods —Standard carotid and vertebral duplex ultrasound protocol was used to evaluate extracranial arteries in 2 groups: I: 8 control subjects, mean age of 49 years, without evidence of carotid or vertebral atherosclerosis, and II: 8 patients, mean age of 48 years, diagnosed with brain death confirmed by electroencephalography. All patients had insignificant (< 50% stenosis) carotid and vertebral atherosclerosis. T-test was used to compare common carotid, internal carotid (ICA), external carotid, and vertebral (VERT) artery resistive indices between Groups I and II. Results —Common carotid (0.74 ± 0.04 vs. 0.88 ± 0.08), ICA (0.60 ± 0.06 vs. 1.00 ± 0.00), and VERT (0.61 ± 0.05 vs. 1.00 ± 0.00) artery resistive indices were significantly lower in normal subjects than in brain death patients (p < 0.05). Both ICA and VERT waveforms in brain death patients demonstrated the oscillatory, “to-and-fro,” pattern already established with TCD. Conclusion —Extracranial ICA and VERT waveforms in patients diagnosed with clinical brain death have the same resistive indices and waveform patterns that have been used to identify brain death intracranially with TCD. Because standard duplex ultrasonography is the most commonly used noninvasive modality for cerebrovascular evaluation, we believe this method may be easier to understand and more readily available for the initial diagnosis of cerebral brain death.
Lateral and longitudinal control of an autonomous racing vehicle.

The development of autonomous and intelligent vehicles is increasing continuously in the aim to reach a reliable and secured transportation system. Indeed, autonomous navigation include three main steps: perception and localization, planning and control. This thesis covers essentially the study of the vehicle modeling and the vehicle control, focused on the coupled lateral and longitudinal control of the autonomous racing vehicle. Three different control strategies are considered: First one based on coupled control while the second one is decoupled control. In coupled controller, adaptive model predictive control (MPC) is used which handles both lateral and longitudinal control. In the decoupled control strategy, longitudinal dynamics is controlled with the help of a PID and Lateral dynamics is controlled first with MPC and second with Lateral controller. The proposed strategy utilizes an adaptive MPC to perform lateral guidance and speed regulation by acting on the front wheel steering angle and acceleration/deceleration to minimize the vehicle’s lateral deviation and relative yaw angle with respect to the reference trajectory, while driving the vehicle within the limits of adherence conditions. While designing the Adaptive-MPC, the internal plant model for MPC is modeled using a linear bicycle model, while dynamics of the vehicle is modeled using a 3 degree of freedom dual-track rigid vehicle model considering the non-linear tire forces derived from a Pacejka model taking into account the slip ratio. The objective is to develop and analyse the three different control strategies and evaluate their design and performance through path following, speed tracking, and ease of implementation. The overall system has been developed using MATLAB® and Simulink®.

Impact of paper industry on Enivironment: A case study from Rajamundry, Andhra Pradesh, India

Pulp and Paper industry has been considered as one of the major polluting industries in the world. The study found that independent variable with significant impact on environmental integrity and economic prosperity was number of countries / states operating in. The independent variables with significant impact on social equity and overall sustainability were number of countries/states operating in and number of fines / penalties / court cases. Though the mill has positive externalities from the point of view of employment and income opportunities, urbanization and concentration of commercial activities and property price appreciation, it has also negative externalities that are environmental pollution which arises from the operation of the mill. This paper attempts to investigate the environmental impact of paper production of the paper mill on agriculture and health.
Modeling and Design of a Multi-Tubular Packed-Bed Reactor for Methanol Steam Reforming over a Cu/ZnO/Al2O3 Catalyst

Methanol as a hydrogen carrier can be reformed with steam over Cu/ZnO/Al2O3 catalysts. In this paper a comprehensive pseudo-homogenous model of a multi-tubular packed-bed reformer has been developed to investigate the impact of operating conditions and geometric parameters on its performance. A kinetic Langmuir-Hinshelwood model of the methanol steam reforming process was proposed. In addition to the kinetic model, the pressure drop and the mass and heat transfer phenomena along the reactor were taken into account. This model was verified by a dynamic model in the platform of ASPEN. The diffusion effect inside catalyst particles was also estimated and accounted for by the effectiveness factor. The simulation results showed axial temperature profiles in both tube and shell side with different operating conditions. Moreover, the lower flow rate of liquid fuel and higher inlet temperature of thermal air led to a lower concentration of residual methanol, but also a higher concentration of generated CO from the reformer exit. The choices of operating conditions were limited to ensure a tolerable concentration of methanol and CO in H2-rich gas for feeding into a high temperature polymer electrolyte membrane fuel cell (HT-PEMFC) stack. With fixed catalyst load, the increase of tube number and decrease of tube diameter improved the methanol conversion, but also increased the CO concentration in reformed gas. In addition, increasing the number of baffle plates in the shell side increased the methanol conversion and the CO concentration.
Fast and Latent Low-Rank Subspace Clustering for Hyperspectral Band Selection

This article presents a fast and latent low-rank subspace clustering (FLLRSC) method to select hyperspectral bands. The FLLRSC assumes that all the bands are sampled from a union of latent low-rank independent subspaces and formulates the self-representation property of all bands into a latent low-rank representation (LLRR) model. The assumption ensures sufficient sampling bands in representing low-rank subspaces of all bands and improves robustness to noise. The FLLRSC first implements the Hadamard random projections to reduce spatial dimensionality and lower the computational cost. It then adopts the inexact augmented Lagrange multiplier algorithm to optimize the LLRR program and estimates sparse coefficients of all the projected bands. After that, it employs a correntropy metric to measure the similarity between pairwise bands and constructs an affinity matrix based on sparse representation. The correntropy metric could better describe the nonlinear characteristics of hyperspectral bands and enhance the block-diagonal structure of the similarity matrix for correctly clustering all subspaces. The FLLRSC conducts spectral clustering on the connected graph denoted by the affinity matrix. The bands that are closest to their separate cluster centroids form the final band subset. Experimental results on three widely used hyperspectral data sets show that the FLLRSC performs better than the classical low-rank representation methods with higher classification accuracy at a low computational cost.
Estudio etnofarmacológico de algunas especies endémicas de agave utilizados en la medicina tradicional

An ethnopharmacological study of the different endemic species of agave in traditional medicine was carried out, from November 2017 to April 2018; through a bibliographic search in books, scientific journals, databases and the internet, carrying out the botanical study, geographical distribution and etymology of the plant. We set ourselves the objective of carrying out this study, to keep the agave as a traditional therapeutic tool and to encourage research by teachers and students for the botanical rescue of this versatile and valuable plant. Also as specific objectives were drawn, to investigate on the medicinal properties of agave from its secondary metabolites and on obtaining a medicinal product from the plant. As significant results we can mention that the plant is considered medicinal, using this information to transmit it to the students through the class plans of the subject Stomatology; A study of the British Agave T. and Agave americana variety was carried out. It was concluded that the medicinal uses of agave are extensive and that products have been obtained from it, of great benefit and esteemed medicinal value.
Mini-posterior approach for primary total hip arthroplasty

Total hip arthroplasty (THA) can be performed safely and with excellent patient outcomes through a wide variety of surgical approaches. In recent years, the advent of so-called ‘minimally-invasive’ surgical approaches has included developments in the surgical approach for THA. The mini-posterior approach (MPA) is one such approach, typically defined as incorporating a standard posterior joint access with more limited muscular dissection and/or incision length <10 cm. This review will attempt to define the MPA, review the available literature on this technique, and discuss the surgical technique in detail.
A Systems-Based Approach to Injury Prevention for the Strength and Conditioning Coach

Participation in sport exposes athletes to an inherent risk of injury. In order to develop a comprehensive injury prevention program, strength and conditioning coaches must conduct a thorough needs analysis to establish the risk of injury, identify mechanisms and risk factors for injury, select relevant screening tests and design targeted interventions based on the athlete’s results. Using a systems-based approach presented herein, this article provides an overview of the process that coaches must undertake in order to develop effective injury prevention programs.
Assessment of secondary central nervous system involvement in patients with lymphoma; MR imaging findings

Secondary central nervous system (CNS) involvement of lymphoma is a rare but critical complication of aggressive systemic lymphomas. We aimed to evaluate the incidence of CNS involvement and the value of magnetic resonance imaging (MRI) of neuroaxis in patients with systemic lymphoma. A total of 205 (93 women, 112 men) patients who have biopsy proven systemic lymphoma and underwent MRI for brain and spinal screening have included into this retrospective study. Based on patient data age, gender, histologic type of lymphoma, duration from initial diagnosis, survey of patients, brain and spinal MRI findings were determined. Secondary CNS involvement observed on 37 patients (18%). There were two HL patient with nodular sclerosing subtype (5.4%) and 35 NHL patients (94.5) were with diffuse large B-cell lymphoma (DLBCL), Burkitt’s lymphoma, mantle cell lymphoma, T-cell lymphoma and B-cell lymphoma subtypes. Nodal disease was 59.4% and extranodal focus of NHL was 31.6%. MRI findings revealed 35 % brain parenchymal lesion, 35% dural enhancement, 29.7% leptomeningeal enhancement, 21.6% cranial nerve enhancement, 13.5% spinal pial-nerve root enhancement, 5.4% ependymal enhancement, 5.4 % hydrocephalus and 2.7% spinal cord lesion. Dural enhancement was significantly higher in nasopharynx (p=0.034) and nodal NHL (p=0.021). Brain leptomeningeal (p=0.021) and spinal pial (p=0.009) enhancement was significantly higher in DLBCL patients. MRI of whole neuroaxis with contrast media is a quite beneficial technique for detecting parenchymal, leptomeningeal, cranial and peripheral nerve involvement in both primary diagnosis and follow-up survival processes of lymphoma.
Safety of Laparoscopy-assisted Distal Gastrectomy in Patients Aged 75 Years or More

Objective: To determine whether Laparoscopy-Assisted Distal Gastrectomy (LADG) is suitable for treatment of gastric cancer in elderly patients, we conducted a retrospective study to examine the safety and outcomes of LADG performed in elderly patients at our hospital. Patients and Methods: Included in the study were 68 patients (15 aged ≥75 years and 53 aged <75 years) who underwent LADG at our hospital. We compared patients’ characteristics (age, sex, and body mass index [BMI]), physical status as defined by the American Society of Anesthesiologists (ASA-PS), medical history, whether endoscopic submucosal dissection (ESD) had been performed previously; surgical factors (operation time, blood loss volume, length of hospital stay, extent of dissection, number of lymph nodes dissected, anastomosis method, time to first flatus, time to first stool, complications); and pathologic factors (tumor location, tumor presence, invasion depth, lymph node metastasis). Results: Mean age of the elderly patients was 79.8 years (75–86 years). Mean BMI was 18.4 (14.3–22.2) kg/m. Three elderly patients were classified into ASA-PS 3, and hypertension was common in the elderly group. The mean duration of surgery was 193.2 (125–290) minutes, and the mean blood loss volume was 52 (4–263) mL. Mean time to first flatus and first stool were 3.0 (2–5) days and 5.3 (4–8) days, respectively. The mean hospital stay was 18.4 (8–48) days. Complications included 1 pancreatic fistula and 1 stenosis associated with an anasto‐ motic ulcer. The mean number of lymph nodes dissected was 33.1 (15–61), and there were 3 cases of lymph node metastasis. Only BMI and the incidence of previous ESD differed between the elderly patients and younger patients. Conclusion: We conclude on the basis of our study findings that laparoscopy-assisted distal gastrectomy can be perfomed safely in patients aged 75 years and older (just as it is in patients under 75 years of age), as long as patient selection is properly carried out.
