Does the water resource ‘fee to tax’ policy alleviate water poverty? Evidence from a quasi-natural experiment
Authors: Mu Lan , Mou Muge , Tang Heyan 
Published: November 2022

Abstract
Levying a water resources tax policy which is called ‘fee to tax’ is a regulation formulated by China to restrain and alleviate water poverty. To test the effect of the water resources ‘fee to tax’, this research employs a multistage dynamic difference-in-differences (DID) model to explore whether the implementation of the policy can help alleviate water poverty based on panel data from 2009 to 2019. The results indicate the water poverty in western China is significantly more serious than in other regions and the implementation of the water resources tax policy significantly alleviates water poverty (the sign of the policy is positive and significant at the 1% level) in China. Additionally, the mechanism effects suggest that the policy can effectively restrain water poverty by reducing groundwater exploitation and optimizing the water utilization structure. In terms of spatial heterogeneity, the effect of the water resources tax policy on alleviating water poverty is stronger in central and eastern regions than in western regions. The conclusions of this study may, to some degree, serve as a basis to scientifically guide the implementation of China's water resources ‘fee to tax’ policy and, thus, effectively improve the level of water resources management.

Authors: Burtsev E. A. , Bronin G. O. 
Published: November 2022

Background. There are increasing data of targeted therapy efficacy of different types of Langerhans cell histiocytosis (LCH) with inhibitors of BRAF-specific serin-threonine kinase (BRAF-inhibitors) in cases with BRAF V600E mutation published last years. At the same time there are no published data of use of inhibitors of MAPK/ERK pathway (MEK-inhibitors) in pediatric patients with BRAF-negative forms of LCH.Purpose of the study is to evaluate efficacy and safety of MEK-inhibitor (cobimetinib) in eight pediatric BRAF V600E-negative refractory LCH patients.Materials and methods. The study included 8 children with various forms of LCH. All patients received therapy according to the LCH-IV protocol and were diagnosed with progression of LCH during or after termination of the treatment. The response to the therapy was assessed in accordance with the international scale Response Evaluation Criteria in Solid Tumors (RECIST v.1.1). The assessment of the toxicity was performed in accordance with the international scale of Common Terminology Criteria for Adverse Events (CTCAE v.5.0).Results. Complete response was not achieved in any patient. Partial response was established in 5 cases. One patient was diagnosed with disease progression in three months after termination of the therapy. The incidence of adverse events was high.Conclusion. Cobimetinib therapy is effective in BRAF V600E-negative refractory pediatric LCH patients. The response to the treatment can be delayed. All cases of the toxicity were dose depended and successfully resolved after dose correction. Further research is needed to define duration of treatment and optimal dosage.

Published: November 2022

Objective. International practices demonstrate advantages of expanded clay in road construction in difficult climatic and geotechnical conditions. The clay is present in abundance in Siberia and in the Far North which is suitable for the production of expanded clay gravel. At the same time there is a strong deficit of the road construction materials in these regions. The aim of the study is to develop a new approach for providing claydite for the construction of northern roads.Method. The modernization of the equipment means that each unit included in the complex can be transported on existing trucks, and then mounted in a line for the production of expanded clay in the field.Result. A mobile complex for the production of expanded clay gravel, serial and modernized equipment for the production of expanded clay has been developed.Conclusion. Large units - drying drums and rotary kilns for drying and firing pellets should be divided into prefabricated sections, for example, with a diameter of 2 m and a length of 5-7 m. For the electric drive of the units, a diesel generator of sufficient power must be included in the equipment set. The productivity of one complex is from 15 thousand cubic meters of expanded clay per year and above.

Background
Ultrasound for gestational age (GA) assessment is not routinely available in resource-constrained settings, particularly in rural and remote locations. The TraCer device combines a handheld wireless ultrasound probe and a tablet with artificial intelligence (AI)-enabled software that obtains GA from videos of the fetal head by automated measurements of the fetal transcerebellar diameter and head circumference.

Objective
The aim of this study was to assess the perceptions of pregnant women, their families, and health care workers regarding the feasibility and acceptability of the TraCer device in an appropriate setting.

Methods
A descriptive study using qualitative methods was conducted in two public health facilities in Kilifi county in coastal Kenya prior to introduction of the new technology. Study participants were shown a video role-play of the use of TraCer at a typical antenatal clinic visit. Data were collected through 6 focus group discussions (N=52) and 18 in-depth interviews.

Results
Overall, TraCer was found to be highly acceptable to women, their families, and health care workers, and its implementation at health care facilities was considered to be feasible. Its introduction was predicted to reduce anxiety regarding fetal well-being, increase antenatal care attendance, increase confidence by women in their care providers, as well as save time and cost by reducing unnecessary referrals. TraCer was felt to increase the self-image of health care workers and reduce time spent providing antenatal care. Some participants expressed hesitancy toward the new technology, indicating the need to test its performance over time before full acceptance by some users. The preferred cadre of health care professionals to use the device were antenatal clinic nurses. Important implementation considerations included adequate staff training and the need to ensure sustainability and consistency of the service. Misconceptions were common, with a tendency to overestimate the diagnostic capability, and expectations that it would provide complete reassurance of fetal and maternal well-being and not primarily the GA.

Conclusions
This study shows a positive attitude toward TraCer and highlights the potential role of this innovation that uses AI-enabled automation to assess GA. Clarity of messaging about the tool and its role in pregnancy is essential to address misconceptions and prevent misuse. Further research on clinical validation and related usability and safety evaluations are recommended.

Cats and dogs have a very close relationship with humans. Currently, the overpopulation of these species in various countries worldwide has been identified as a severe public health problem. To establish effective programs for population control, it is necessary to estimate the number of cats and dogs. To our knowledge, there are no studies that assess the number of canine and feline population by state in Mexico. Therefore, this study aimed to estimate the canine and feline population living at homes using official information reported by the National Institute of Statistics, Geography and Informatics [Instituto Nacional de Estadística Geografía e Informática] through a constant-share model, a ratio extrapolation method. The estimated dog population living at homes was 42 625 010 dogs and 7 346 925 cats (at least 5.8 times less than the number of dogs). By 2022, the Mexico's estimated human:dog ratio was 2.4:1, and the human:cat ratio 17.6:1. The Estado de México had more than six million dogs and 962 177 cats. Colima had the smallest estimated dog population (245 489), and Baja California Sur the smallest estimated cat population (slightly over 30 000). Health authorities and veterinary practitioners should promote responsible ownership to increase veterinary care and control the birth of dogs and cats.
Shareholder Activists and Frictions in the CEO Labor Market
Authors: Keusch Thomas 
Published: November 2022

ABSTRACTUsing hand-collected data on CEO appointments during shareholder activism campaigns, this study examines the relation between activist involvement in CEO recruiting and frictions in CEO hiring decisions. The results indicate that appointments of CEOs who are recruited with shareholder activist influence are associated with more favorable stock market reactions and stronger profitability improvements than appointments without activist involvement. In contrast, I find little evidence that shareholder influence is followed by the recruitment of CEOs who implement myopic corporate policies. Additional analyses reveal positive associations between activist involvement and (1) the amount of resources being dedicated to the CEO search process and (2) the propensity to recruit CEOs from outside the firm. These findings extend the CEO labor market literature, which so far focuses mainly on the decision to remove incumbent CEOs and provides limited insights into CEO recruiting.JEL Classifications: G23; G32; G34; M12; M51.

Authors: Sukerte Nyoman 
Published: November 2022

Kabupaten Lampung Barat yang merupakan wilayah tiga hulu sungai besar atau tiga Daerah Aliran Sungai (DAS) yaitu Way Besai, Way Semangka dan Way Musi haruslah terjaga dengan baik. Kerusakan vegetasi hutan menjadikan laju sidimen tidak terkendali dan pendangkalan dasar sungai yang berakibat rusaknya alur sungai serta terjadinya banjir di daerah hilir. Berkurangnya resapan menyebabkan meningkatnya limpasan air permukaan dan waktu konsentrasi air semakin pendek berakibat banjir bandang.
Curah hujan yang sangat tinggi berkisar antara 2.500 – 3.000 mm per tahun dan daerah yang berbukit serta kerusakan vegetasi pada daerah aliran sungai, yang mempermudah terjadinya longsor, alur sungai yang berkelok dengan kemiringan dasar sungai yang besar menyebabkan laju sidimentasi yang tinggi. Mitigasi terhadap kondisi ini harus segera dilakukan dengan cara-cara pengendalian banjir mulai dari bagian hulu yaitu dengan membangun tampungan-tampungan air untuk memperlambat waktu tiba banjir dan menurunkan besarnya debit banjir. Penghijauan di Daerah Aliran Sungai dan pembuatan waduk lapangan yang dapat merubah pola hidrograf banjir. Bangunan pengendali banjir yang sesuai dengan kondisi Kabupaten Lampung Barat yang berada di bagian hulu beberapa Daerah Aliran Sungai (DAS) di Provinsi Lampung dan Provinsi Sumatera Selatan adalah bangunan air yang besifat bangunan konservasi berupa retention basin, detention basin dan retarding basin.
Hal ini sangat relevan dengan komitmen Kabupaten Lampung Barat sebagai kabupaten konservasi. Kegiatan yang bersifat konservasi harus segera direalisasi secara berkesinambungan sehingga memberikan banyak dampak menurunkan kejadian banjir dan kerusakan sungai, serta menambah ketersediaan air.

Observing Instructor Behaviour in an Active Learning Classroom: A Case Study of an Undergraduate Calculus Course
Authors: Shahid Iflah , Van Beek Alison , McCahan Susan 
Published: November 2022

Active learning classrooms (ALCs) are spaces explicitly designed to encourage collaborative learning, often through the use of technology. To learn more about teaching activity in ALCs, a study was designed to observe an engineering calculus course during the winter 2020 term. A large-scale active learning classroom was selected for classroom observation using the extended Teaching Dimensions Observation Tool (TDOP+). The TDOP+ is a descriptive classroom observation protocol based on the Teaching Dimensions Observation Tool, enhanced with elements from the Active Learning Classroom Observation Tool (ALCOT).
This case study compares the class orchestration of different instructors teaching two different sections of the same course at a large, public university. Twenty class sessions were coded for this study: 10 for each section (5 for each instructor). The coded instructor behaviour was analyzed using a conceptual framework described by Nocera (i.e., a version of Activity Theory), focusing on mediating artifacts and instructor goals.
While we observed differences in the frequency and duration of active learning activities and in the type and number of tools used in each class session, the results from this case study suggest that flexible space design enables instructors with the same lesson plan (and content) to create different technological frames to achieve their varied pedagogical goals, while encouraging increased adoption of new tools.
Novel Work-Integrated Learning Model Based on the German Education System: UQTR’s Dual Approach for its Mechanical Engineering Program.
Authors: Goyette Mélissa , Gaudreau Marc-André , Baril Chantal 
Published: November 2022

This paper presents the German-inspired education model called Dual, as pioneered by l'Université du Québec à Trois-Rivières (Drummondville Campus) for its mechanical engineering undergraduate degree. Focus is on the program structure itself and the ongoing research project which aims to determine and measure outcomes of this novel approach from the student, industry-supervisor and professor perspectives’, specifically pertaining to their respective experience, impact on academic performance, employability, and the development of work-related skill sets. The methodology is set forth in this paper and results from similar experiences across Europe are presented. Qualitative and quantitative data for this specific project are still being collected and analyzed. The proposed model for this research stems from studies on active, experiential and work-integrated Learning. Motivated by a desire to better prepare engineering students for the ever-changing realities of the profession and as a response to the shortage of qualified personnel faced by the industrial sector, the program combines parallel on- and off-site learning over a consecutive two-year period. This differs from the more commonly known co-op structure where students alternate between study terms and work terms. With the proposed dual model, students complete the program within 4 years earning 24 credits, of a total 120, through work-integrated learning directly at the workplace (off-site). Courses completed jointly at the school and in partnership with the company include a 9-credit capstone design project and two 3-credit complementary courses, where reflective journaling and mentorship are central to both. In addition, three 4-month internships are also completed. Since June 2021, the program is accredited by Engineers Canada.
Survey Results: How Does Lifelong Learning Enable Alumni Careers?
Authors: Dawe Nikita , Romkey Lisa , Bilton Amy 
Published: November 2022

This paper presents findings from an engineering alumni survey intended to understand the role of lifelong learning in graduates’ careers. It builds on prior work aiming to clarify how engineering programs should address the important but nebulous CEAB graduate attribute. By contrasting alumni responses to the existing graduate attribute definition, we find opportunities to reconsider and clarify how the lifelong learning attribute is conceptualized.
Survey respondents (n = 279) came from two undergraduate engineering departments at our institution and graduated between 1991 and 2020 (i.e. 1-30 years after graduation). Overall, respondents rated “maintaining competence in the field associated with your undergraduate degree” and “contributing to the advancement of knowledge in the field associated with your undergraduate degree” as less important than factors related to developing competency and advancing knowledge in domains outside of their undergraduate degree fields. Learning from others, learning for the purpose of innovating, and learning to develop empathy and emotional intelligence were additional factors that are not inherent in the CEAB definition of lifelong learning. These findings have implications for accreditation and licensure body intentions as well as the content and pedagogy of undergraduate curriculum.
