Monetary Policy And Stagflation: A Trade-Off Between Price Stability And Economic Growth?, Leef H. Dierks

Journal of New Finance

Several euro area economies are likely to experience a stagflation in 2023. This situation is characterized by a combination of economic stagnation, i.e., GDP growth falling below its potential growth rate, and a pronounced increase in inflation as was last observed during the 1970s’ oil crisis. A stagflation presents the European Central Bank with a dilemma. Should it further tighten its monetary policy in an attempt to align euro area inflation (expectations) with its target of two per cent p.a. in the medium term? Or should the ECB re-adopt a more accommodative stance so as to stimulate economic growth in …

The Effect Of A Personalized Learning Model On The Mathematical Achievement Of Elementary Students, Jaclyn L. Pedersen

Education Theses and Dissertations

This is a two-year mixed-methods study designed to discover the effects of a personalized learning model on the mathematical achievement in elementary. The setting is a university laboratory school that utilizes a distinct instructional math model based on mathematical best practices, problem-based learning (PrBL), and the use of personalized learning (PL) through stations, small-group pull-outs and a designated software program (IXL). The evaluation study was conducted over the course of a year. Teacher observations were used to understand the implementation of the model as well as the teacher’s perceptions. Student data from the previous year’s state assessment, State of Texas …

Rethinking The Image Of The Child And Re-Imaging Schools, Juana Reyes

Education Department Faculty Articles

Over the last few years, there have been many calls to re-imagine schools. These recurring calls for reconceptualization of schools only intensified during the pandemic: What might schools look like post pandemic? How can we re-conceptualize schools and move away from antiquated practice that was initially built based on an agrarian society that had to address the influx of immigrants who were diverse in culture and language? The initial iteration of schooling in the United States was focused on the melting-pot ideology of assimilating immigrant and indigenous students into a mythical American ideology. The original system wasn't concerned with respecting …

Collaborative Decision Making Improves Interpersonal Psychotherapy Efficiency: A Randomized Clinical Trial With Postpartum Women, Scott Stuart, Rebecca L. Brock, Erin Ramsdell, Stephan Arndt, Michael W. O'Hara

Department of Psychology: Faculty Publications

Background: Randomized controlled trials of Interpersonal Psychotherapy (IPT) and other psychotherapies for depression have required strict adherence to protocol and do not allow for clinical judgment in deciding frequency of sessions. To determine if such protocols were more effective than allowing therapists to use their clinical judgment, we compared “Clinician- Managed” IPT (CM-IPT), in which clinicians and patients with postpartum depression were allotted 12 sessions and determined collaboratively when to use them, to a once weekly 12 session protocol (“Standard IPT”). We hypothesized that CM-IPT would be more efficient, requiring fewer sessions to reach an equivalent acute outcome, and …

Social Work: School of Social Work Faculty Publications and Other Works

Highly educated immigrants are part of the growing population of immigrants who are impacted by the increasingly hostile migration policies in the U.S. This qualitative study used a phenomenological approach and inductive reasoning to explore the possible impacts of migration integration policies as social determinants of health among this group. Data was collected through 31 semi-structured interviewees with highly educated immigrants who had an intention and interest to stay in the U.S. at the time of the interview. Data were analyzed using reflexive thematic analysis and four main themes emerged: (1) a life overshadowed by silent worries, (2) living through …

Experimental Study On Interface Fatigue C Haracteristics Of Asphalt P Avement Pothole Patch Under External Factors, Ai Changfa, Shao Zhutao, Huang Yangquan, Ren Dongya

Journal of China & Foreign Highway

After the asphalt pavement patch for potholes is put into use, the interface joints around it are prone to fatigue and durability problems under the action of external factors such as the natural environment and driving load effect. In order to analyze the fatigue characteristics of the repaired interface joints under the action of external factors, the four-point bending fatigue test and pull-out test, combined with the results of orthogonal analysis, were used to determine the best bonding scheme of the repaired interface. The influence of external factors such as temperature, frequency, and strain level on the fatigue life of …

Study On Improvement Of Early Skid Resistance Of Sma Asphalt Pavement Based On Spreading Grit, Jiang Zhaowei, Wei Jincheng, Liu Hang, Sun Qiang, Li Xia

Journal of China & Foreign Highway

The early skid resistance of SMA 13 pavement is poor. To address this issue, the existing research results were analyzed, and physical detection was conducted. It was found that the large structure pavement failed to provide good early skid resistance detection value. Based on the principle of spreading abrasive materials, two methods to improve the early skid resistance of SMA pavement were proposed. The particle size of abrasive material was determined to be 2.36–4.75 mm, and the spreading amount was 0.82 kg/m2, which verified the safety of the methods. The test results show that the two methods can slightly improve …

Based on the virtual shear test and laboratory direct shear test, the effects of construction technologies and amount of adhesive oil on the interlayer shear strength of double-layer drainage pavement were analyzed. By means of visualization, the distribution …

Design And Stress Analysis Of Baqiutian Jointless Arch Br Idge In Yunnan, Chen Baochun, Sun Tongqing, Huang Qingwei, Han Yu, Shi Zhi

Journal of China & Foreign Highway

The bridge without expansion joints, with the expansion device removed, can completely solve the maintenance problem of the expansion device and is sustainable. Its application is mainly in beam bridges and relatively few in arch bridges. In this paper, the Baqiutian Bridge in Yunnan Province was taken as an example, which is an upper bearing arch bridge. The arch path structure is directly connected with the two approach spans to form a continuous structure and extends to the guide plate (approach slab) behind the platform, thus eliminating the expansion joints of the whole bridge floor and making it an arch …
