The high cost of protecting Uruguay's automotive industry
No full textDomestic content requirements are regulations that mandate minimum percentages of domestic value-added, or domestic components for products sold within the country, or provide strong incentives to substitute domestic for imported inputs. The author developed a model to investigate the distortions, costs, and transfers among groups caused by the combination of domestic content and compensatory export requirements. This model was applied to the protection scheme for Uruguay's automobile industry. The author found that the protective regime keeps vehicle prices and domestic production costs high and transfers large sums to special interest groups. Higher finished vehicle prices encourage more output from domestic assembly operations, but domestic content and compensatory export requirements discourage domestic assembly. The net effect could either encourage or discourage domestic assembly operations, depending on the net impact of the regulations. Trade in this industry should be liberalized. Care should be taken not to inadvertently increase effective protection of the assembly industry by, for example, phasing out domestic content and compensatory export requirements on kits faster than those on finished autos, thus temporarily encouraging domestic assembly.Economic Theory&Research,Environmental Economics&Policies,Access to Markets,Markets and Market Access,Water and Industry
The Effect of Aromatherapy and Su Jok Interventions on Post-Cesarean Pain
No full textELMALI SIMSEK, HULYA/0000-0003-0372-1981Objective: The aim of this study was to determine the effect of aromatherapy and Su Jok interventions as non-pharmacological methods of relieving pain after cesarean section. Materials and methods: This randomized controlled trial was conducted with 120 women who had cesarean delivery in the gynecology and obstetrics department of a training and research hospital between February 9 and October 2, 2019. The participants were allocated to the aromatherapy group, Su Jok group, Su Jok and aromatherapy group, or control group using block randomization based on parity. Su Jok was performed using buckwheat seed; aromatherapy was applied using lavender, eucalyptus, or rose oil. Data were collected using a participant information form and pain was assessed using the Visual Analog Scale. Results: There was no significant difference between the groups in mean pain levels before or after the intervention, although the control group had less initial pain compared to the intervention groups. However, all three intervention groups showed significant decreases in pain levels immediately and 30 min after the intervention compared to pre-intervention levels (p < 0.05). The intervention in all three groups reduced the level of pain. In particular, the pain level of the Su Jok group reached from moderate to mild. There was no significant change in the control group. Conclusions: Aromatherapy and Su Jok interventions performed separately and simultaneously in addition to routine hospital care were more effective in reducing post-cesarean pain than routine care alone.Science Citation Index Expande
Lattice matching for detecting distributed intrusions
No full textIntrusion detection systems (IDS) are crucial components of the security mechanisms of today\u27s computer systems. Intrusion detection has been an active field of research for about three decades. Existing research on intrusion detection has focused on sequential intrusions. However, intrusions can also be formed by concurrent interactions of multiple processes. Some of the intrusions caused by these events cannot be detected using sequential intrusion detection methods. Therefore, there is a need for a mechanism that views the concurrent system as a whole. L-BID (Lattice-based intrusion detection) is proposed to address this problem. In the L-BID framework, a library of intrusions and collected distributed system traces are represented as lattices. Then these lattices are compared in order to infer to the existence of intrusion in the collected distributed system traces. The similarity between these lattices is used as a quantitative metric for L-BID. The applicability of lattice matching method to the concurrent intrusion detection problem is investigated and the challenging aspects of this work are outlined --Abstract, page iii
Aspects of critical spin 1 chains and 2 dimensional symmetry protected topological phases of matter
No full textEffective field theory is a very useful technique for understanding quantum many body systems. We use this approach to study a certain class of critical quantum spin-1 chains and symmetry protected topological phases of matter in two spatial dimensions.
In the first context we consider the SU(3) symmetric spin-1 chain with additional interactions. We use bosonization to demonstrate that the effective field theories describing the critical behaviour of these spin chains can be mapped to free compact boson conformal field theories (CFTs) with central charge c=2. We also describe how some predictions from field theory can be verified in numerical calculations using exact diagonalization (ED) and the density matrix renormalization group (DMRG) algorithm. In particular, the bosonization method gives a formula for the evolution of four Tomonaga-Luttinger liquid (TLL) parameters as a function of the lattice parameters. Using the analytic formulae for the scaling dimensions in terms of the TLL parameters and matching of lowest scaling dimensions, we numerically calculate these field-theoretic parameters and confirm that their evolution agrees with the prediction using bosonization.
We also tackle aspects of the challenging problem of understanding interacting topological phases. In this context, we aim to understand the effects if interactions in certain classes of symmetry protected topological (SPT) phases of matter. We consider non-chiral SPT phases in two spatial dimensions protected by a discrete symmetry such as Z_K or Z_K x Z_K symmetry. We argue that modular invariance/noninvariance of the partition function of the one-dimensional edge theory can be used to diagnose whether, by adding a suitable potential, the edge theory can be gapped or not without breaking the symmetry. By taking bosonic phases described by Chern-Simons K-matrix theories and fermionic phases relevant to topological superconductors as examples, we demonstrate explicitly that when modular invariance is achieved, we can construct an interaction potential that is consistent with the symmetry and can completely gap out the edge.
We also briefly discuss preliminary results of a numerical approach for simulating the 3 dimensional Landau Level problem. This includes a brief description of a potential application of variational Monte Carlo to spin-orbit coupled ab initio systems.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Olabode Sule, accepted the attached license on 2016-02-02 at 18:25.The student, Olabode Sule, submitted this Dissertation for approval on 2016-02-02 at 18:39.This Dissertation was approved for publication on 2016-02-03 at 13:28.DSpace SAF Submission Ingestion Package generated from Vireo submission #9061 on 2016-07-07 at 13:48:12Made available in DSpace on 2016-07-07T20:26:46Z (GMT).

The macroeconomics of the public sector deficit : the case of Morocco
No full textThis paper tries to uncover the reasons underlying the performance of the Moroccan economy. The author argues that wage moderation and judicious monetary policies were instrumental in restraining inflation. With one brief exception in 1983, monetary authorities remained firmly committed to eschew any inflationary financing of the budget deficit. This strategy could only succeed however because of the wide ranging system of credit and monetary regulations which worked to channel domestic funds toward the Treasury at relatively low costs. The prospects for the continuation of such a strategy are not favourable however. As far as the growth performance is concerned, it appears that it can be attributed to an outstanding export response to the new trade regime on the one hand and a set of favourable supply shocks, including a string of recordagricultural harvests and the collapse of real oil prices, on the other. The paper studies the evolution of the budget and its different components and argues that the reluctance by Morocco's policy makers to monetize existing budget deficits is well explained by the sharply unfavourable trade-offs between higher monetization and inflation existing in Morocco. It analyzes the implications that continuing budgetary disequilibria has on investment and saving decisions and finds that such implications may be substantial, even though they may not work their way exclusively through traditional interest rates channels.Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Public Sector Economics&Finance,Financial Intermediation

No full textCultural adaptation, validity and reliability of the Turkish version of the Orebro Musculoskeletal Pain Questionnaire in acute and subacute neck pain
No full textBackground/Aims The Orebro Musculoskeletal Pain Questionnaire is categorised as a 'yellow flag' pain-associated psychological distress screening tool, which predicts long-term disability. The aim of this study was to assess the validity and reliability of the Turkish translation of the Orebro Musculoskeletal Pain Questionnaire in patients with acute and subacute neck pain. Methods The test-retest reliability and internal consistency were assessed with the intraclass correlation coefficient and Cronbach's a. Construct validity was assessed with a visual analogue scale, the Neck Disability Index and the Fear Avoidance Belief Questionnaire. Results Cronbach's a value was found to be 0.790, test-retest reliability was 0.99. The intraclass correlation coefficient was 0.999 (95% confidence interval: 0.998-0.999; P=0.000). The Orebro Musculoskeletal Pain Questionnaire showed a moderate positive correlation with the Neck Disability Index (r=0.544; P=0.0001), a weak correlation with the Fear Avoidance Belief Questionnaire (r=0.264; P=0.0001) but no correlation with the visual analogue scale. Conclusions The Turkish version of the Orebro Musculoskeletal Pain Questionnaire is a valid, reliable and acceptable screening tool in patients with acute and subacute neck pain
The Effect of Back School Program on Fear Avoidance Behavior, Disability and Pain in Chronic Mechanic Low Back Pain
No full textAim: The aim of this study is to investigate the effect of back school program on pain, disability and fear avoidance belief in chronic mechanical low back pain patients. Material and Method: 54 chronic mechanical low back pain patients enrolled in the study. Pain intensity levels at rest and activity were measured by numerical rating scale. Oswestry Disability Index (ODI) was used for measuring functional disability level and Fear Avoidance Belief Questionnaire (FABQ) was for fear avoidance belief. Back school and home exercise program was performed on 28 patients in the experimental group. Control group consist of 26 patients was followed with home exercise program only. Results: No significant difference was found in terms of pain intensity, disability level and fear avoidance belief scores at initial assessment of the groups. Improvement has been identified in pain, disability level and fear avoidance scores for both groups at 3 week follow up. There was no significant difference in terms of pain intensity, disability level and fear avoidance belief scores on 3 week follow up assessment between groups (p>0,05). There was significant difference in FABQ work activity scores between groups at 3 months follow up assessment (p0,05). When it compares to differences between 3 week and 3 months follow up assessment, there was statistically significant difference in favor of education group between ODI and FABQ scores (p 0,001). Discussion: Back school program reduces the level of disability and fear avoidance behavior in the medium term. Our study showed that back school is not only posture and activity education program but also has an important part of the treatment on psychosocial aspects
