Authors: Aungkawattanapong Nadvadee , Jakchai Ketsuda , Tempark Therdpong , Bongsebandhu-phubhakdi Chansuda
Published: July 2022

Objectives

Post-traumatic brain injury hypopituitarism is a common unrecognized condition in children after head injury. Due to its similarity of clinical symptoms with those of head trauma, clinical diagnosis of post-TBI hypopituitarism is challenging. To date, there is no standardized screening protocol for children with history of brain injury. This article demonstrates a case of 14-year-old boy with severe head trauma who developed refractory seizures with episodic hypoglycemia and weight loss. We aimed to focus on the prevalence, clinical courses and clinical implementations of each hormonal axis in children with post-traumatic brain injury hypopituitarism. We also aim to raise awareness of this condition to pediatricians in light of enhancing patient care.

Methods

We have searched for original articles, published in English between year 2000 and 2021. There are 20 related articles, authors reviewed all the articles independently.

Results

Prevalence of post-traumatic hypopituitarism ranges from 5–57% in children. Growth hormone is the most commonly affected hormone. The highest prevalence is 42.3% at more than 12 months after the brain injury. The symptoms and severity range from asymptomatic to requiring long-term hormonal therapy. Although normalization of pituitary function is demonstrated at various times after the injury, hormone replacement therapy is still required in some patients.

Conclusions

This is the first report that demonstrates a presenting symptom of hypopituitarism mimic traumatic brain symptoms which result in it being overlooked. This case emphasizes the need to develop pituitary function screening protocols for children with TBI. We have proposed our pituitary screening protocol for children with TBI in this article.
Online Image and Self-Presentation: A Study on Chinese Rural Female Vloggers
Authors: Li Zhi , Zhu Huijie
Published: July 2022

Purpose

The purpose of this empirical study is to examine how Chinese rural female vloggers present and express themselves online when they are increasingly exposed to the Internet, and to analyze the motivations of their self-expression and whether the media images on the Internet correctly reflect the real life of rural women in China.

Design/methodology/approach

We conducted content analysis and case studies on 30 rural female vloggers and 2580 videos selected from Xi Gua Video, one of the most popular video platforms in China. The English name of Xi Gua Video is Watermelon Video. It belongs to the same company as Douyin(the Chinese version of Tik Tok) and has a large number of creators. There is a Rural category in Xi Gua Video which shows its importance to the video platform.

Findings

Married women are the mainstay of rural female vloggers, and they tend to use unique username settings. Among different avatars, a confident smile is the mainstream. The themes of the videos mainly center on rural family life. Based on the analysis of the video themes, we speculated that whatever techniques rural women take for video shooting, their image formation is still subject to the gaze of men and the patriarchal social order. In general, they are still disciplined, though their self-awareness has already begun to awaken.

Research implications

The research unveils the gendered frame behind the rural-related short videos in contemporary China. It can also help the rural female vloggers identify themselves.

Practical implications

Internet policymakers can guide the dissemination of short videos of rural women based on this research, thereby improving the status and lives of rural women.

Originality/value

This is an empirical study to examine the rural Chinese female vloggers’ attitude and cognitive competence based on the feminist theory.
Britain In or Out of Europe During the Late Mesolithic? A New Perspective of the Mesolithic–Neolithic Transition
Authors: Lawrence Tom , Donnelly Mike , Kennard Liz , Souday Caroline , Grant Rose
Published: July 2022

Lacking well-dated fifth millennium Mesolithic evidence and based on a consensus that late Mesolithic Britain was isolated from the continent, discussion of the Mesolithic–Neolithic transition has focused on the centuries around 4000 BC. This discourse has over-simplified complex neolithisation processes. New, high-quality evidence from 460,000 lithics found at Bexhill, Sussex, SE England, helps to redress this. Here, well-dated Mesolithic microliths (5500–4300 BC) may demonstrate continental links with neolithised communities. Alongside other sites, this offers exciting opportunities to contribute to debates on an isolated late Mesolithic during the transition. As a result, this work also provides additional explanations of new evidence proposing European influences on British Neolithic DNA. Instead of an isolated island, with this lithic evidence, we propose that the late Mesolithic Britain was culturally connected to the neolithised continent in the fifth millennium. Therefore, the Mesolithic–Neolithic transition of Britain was a longer, more complex, and nuanced process than previously thought.
Empirical formula for pre-formation probability in actinide region within unified fission model
Authors: Sowmya N. , Manjunatha H. C. , Munirathnam R.
Published: July 2022

An improved semi-empirical formulae for pre-formation probability is proposed within unified fission model. The role of pairing effect and shell correction term were taken in to account. Around 39 even–even (E–E) nuclei, 24 even–odd (E–O), 29 odd–even (O–E) and 14 odd–odd (O–O) nuclei were considered in the atomic and mass number range 89 ≤ Z ≤ 103 and 206 ≤ A ≤ 257 respectively. The standard deviation are evaluated for Zhang et al. [Phys. Rev. C 95, 014311 (2017)], Ismail and Adel [Phys. Rev. C 88.054604 (2013)], Seif et al. [Phys. Rev. C 92, 044302 (2015)] are evaluated. We have also compared the standard deviation of present work with that of available semi-empirical formulae. The standard deviation using Royer [J. Phys. G: Nucl. Part. Phys. 26 1149 (2000)] in case of E–E is smaller when compared to present work. In all other cases the standard deviation obtained from the present work is smaller when compared to other studied semi-empirical relations. Hence, involvement of pairing effect and shell correction term of parent nuclei in the pre-formation probability reproduces experimental α-decay half-lives in the actinide nuclei. As a result, the current work’s detailed examination of the unified fission model and application of pre-formation probability may be utilised to anticipate unexplored isotopes in actinide nuclei.

Published: July 2022

The aim of this paper was to examine the application of the Automatic Exchange of Information (AEoI) agreement through the point of view of Economic Analysis of Law Theory. This study used a normative legal method with a statute approach, conceptual approach, and comparative approach. The result of this study indicated that: first, AEoI has caused a relocation of deposits but has not led to significant repatriation of funds. The least compliant country of AEoI receives incentives in the form of transferring funds from countries that are aggressively implementing AEoI. Hence, in general, it does not change the amount of funds managed abroad. Second, by using game theory: prisoner's dilemma, it is known that the best decision for Indonesia to respond to the AEoI is to conduct a moratorium on the AEoI agreement.

Utilizing Chickpea Isolates as a Fortificant to Develop Protein-Dense Yogurt: A Review
Authors: Arya Nikita , Kumar Rajendra
Published: July 2022

Pulses and dairy products are recognized for their nutritional and functional benefits and are consumed in various forms. Yogurt is considered a source of good quality protein with anti-carcinogenic, hypocholesterolemic properties, and palliating effects on lactose intolerance. Similarly, chickpea is known for its high protein content, low glycemic index, and hypoglycaemic effects. These food ingredients cater to numerous advantages for human health and can address public health issues related to malnutrition or other nutritional deficiencies. With this background, the manuscript explores the possibility of employing chickpea isolates to fortify yogurt to improvise protein content along with sensory and physicochemical properties. So far, the literature has shown that protein extracts, when added to yogurt, result in gaining protein content and overall product quality. The yogurt market is growing, and consumers from different countries have expressed their willingness to purchase fortified yogurts to achieve optimum health. Therefore, developing a new combination of yogurt and chickpea isolates can provide a therapeutic alternative to enhance the nutritional status of the vulnerable population, viz. children, pregnant, lactating mothers, elderly, sportsperson, etc., when a judicious food intake is a must.

Authors: Oliveira Lucas N , O. Nascimento Eriberto , L. Antonio Patricia , V.E. Caldas Linda
Published: July 2022

Dosimetric evaluation is indicated for material characterization seeking to identify possible applications; still, proper preprocessing techniques are critical features of this process. This work aimed to determine the linearity response of plastic samples irradiated with gamma rays using the Fourier Transform Infrared (FTIR) measurements. The plastic samples were analyzed using Derivatives and Principal Component Analysis (PCA) methods. They applied linear and Principal Component Regression (PCR) methods to obtain linearity. The methods obtained good results for linearity and also showed the evolution of each technique. In conclusion, the results indicate that the applied methods can be useful in radiation physics and for plastic samples as interesting potential radiation detectors.

Authors: Ferrari Ferraz Ricardo , Ferreira Sousa Jaine , Batista Reis Lima Héstia Raissa , Pessoa Oliveira Raquel Aline
Published: July 2022

The structural and morphological properties of the novel chromium-doped β-spodumene based ceramic pigment were evaluated aiming to study its chemical and thermal stability in industrial applications. The pigment samples were synthesized by the proteic sol-gel method using gelatin as a ligand. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were performed. Rietveld refinement of experimental diffractograms and average crystallites size by the Scherrer’s method analysis were carried out. XRD results confirmed that the crystal structure of lattice corresponded to β-spodumene and the Rietveld refinement indicated the absence of structural changes with doping up to 3% of chromium. Scherrer’s method indicates that there are no trends changes in the average size of crystallites in the analyzed doping contents. SEM analysis indicated that there are no morphological changes in the chromium-doped particles. The present study concluded that structural or morphological alterations are not noticed for β-spodumene samples produced with chromium doping up to 3% by weight, and that this pigment possibly preserves the chemical and thermal stability of pure β-spodumene. The absence of changes in these properties by doping with low chromium contents were attributed to possible substitutions of Al3+ by Cr3+ ions in the β-spodumene crystal lattice.
Comparison between two methods for estimation of Equilibrium Dose in MSCT procedures
Authors: Stefani Yuri , Nersissian Denise , Costa Paulo
Published: July 2022

The CTDI100 underestimates the dose indicator due the scattering beyond the scanning length of 100mm of the measurement. A proposed method to obtain the dose (including the “tail” of the dose distribution) is a measurement on a large phantom to estimate the dose indicator on an ideal infinitum large phantom (equilibrium dose). As the scanning length increases, the dose indicator grows asymptotically. Measuremente previously obteined with three tied phantoms of PMMA were adopted in the present work. It includes a set of length measured for different combinations of protocols of voltage, pitch, diameter and axis of measurement. Using an empirically characterized function of the experimental data, two methods to estimate the equilibrium dose were evaluated. One method is manipulating algebraically of the function, and another is the use of Levenberg-Marquardt least-squares. The comparative evaluation of both methods demonstrate that in higher values of the pitch results in a higher difference of both methods. The results demonstrate a good compatibility of the methods for the estimation of the quantity Deq. However, the results for alfa and Leq are significantly different when both methods are considered.

Published: July 2022

Approaches to form new materials for radiation dosimetry are essential to enhance quality assurance and quality improvement practices based on radiation protection concept. The present work reports a hydrothermal synthesis based on a relative low temperature and pressure to form thulium-yttria nanoparticles with electron paramagnetic resonance response. Thulium-yttria nanoparticles were prepared and characterized by XRD, SEM, PCS, and EPR. According to results, the hydrothermal method provided thulium-yttria nanoparticles with cubic C-type structure, mean particle size (d50) less than 160nm, and EPR response. The EPR spectra of powders exhibited two resonance peaks p1 and p2 recorded at 350 and 160mT, respectively. The enhancement of the EPR response of yttria by the use of thulium as a dopant provide meaningful parameters to advance in the formation of new rare earth based materials for radiation dosimetry.

Published: July 2022

The use of fluoroscopy equipment in surgical procedures exposes professionals to ionizing radiation. An important safety aspect is the correct use of personal protective equipment and monitoring of dose levels in workers. In Brazil, the Resolution of the Collegiate Board of Directors (RDC) No. 330/2019 demands the use of individual dosimeter for professionals who exceed the public dose limits. However, when personal dosimeters are not available, the International Atomic Energy Agency (IAEA) recommends attaching a dosimeter to the C-Arm, close to the detector, to estimate the dose received by medical personnel. The objective of this research was to evaluate the levels of exposure in professionals during surgical procedures in the operation room. This analysis was performed by placing OSL dosimeters on the C-arm equipment for eleven months and comparing them with the quantitative values extracted from the equipment in the routine. Two mobile fluoroscopies C-Arm equipment were used in this study. A total of 1231 procedures were evaluated, with a mean dose value of 5.8µSv per procedure. Thus, the maximum number of procedures that the same professional can perform was 140 procedures per day for a staff member considering worker dose limits and 7 procedures per day for staff members using the required protective aprons considering the public dose limits. Although the study shows that the dose limits established by regulatory bodies are above the doses recorded in clinical practice, this situation should not promote false safety in the use of ionizing radiation.

Effect of blue light bleaching in a high TL sensitivity natural quartz crystal
Authors: Soares Bruno , Asfora Viviane , Guzzo Pedro
Published: July 2022

The quartz dating can be performed from optically stimulated luminescence (OSL) or thermoluminescence signals (TL). The relationship between OSL and TL signals is important to ensure adequate measurement of luminescent signal. The bleaching effect on TL signals have been studied by various works. However, there is no consensus. This study investigates the effect of blue light bleaching in a natural quartz crystal whose TL signal can be recorded with test-doses lower than 1 Gy. As a result, it was found that blue light is capable to erode almost completely de first TL peak. The bleaching effect for TL peaks above 200 °C is limited. However, TL components peaked at 320 and 390 °C are more sensitive to blue light than the intermediate TL components peaking at 250 and 280 °C.

Authors: Vieira Lucena Julia , Rojas Rocca René
Published: July 2022

The main objective of this work was to study a new technique for the sintering of marine sodium chloride (NaCl) crystals obtained from seawater. In order to obtain an efficient luminescence, a better control in the amount of sample to be used, a better distribution of crystals in every aliquot and verify its applicability as a dosimeter, with dosimetric requirements testing. The common salt is a material that have been already studied in the area of ​​dosimetry, because it has a high sensitivity when exposed to ionizing radiation, therefore can thus be used in luminescent dosimetry. With the purpose of synthesizing the marine crystals with low cost and easy fabrication, we pulverized a concentrated sea salt solution, on 1 cm recycled aluminum discs placed on an oven at 70aºC, with this process we obtained homogeneous aliquots. The salt has a hygroscopic property, we waterproof it using a commercial enamel, in order to inhibit this property. For analyzing the crystalline structure formed with this new technique, we used X-ray diffraction (XRD). For OSL measurements, we use the RISØ TL/OSL reader by blue light stimulation (470 nm) coupled with a beta source, at first, the heat treatment was carried out on the aliquots at 400 ºC, at different times to observe the effect on the OSL signal, irradiated with a dose of 162 mGy, with preheating at 160 °C for 1 s, afterwards we perform a measurement with an assisted temperature of 110 °C for 40 s with blue light. Lastly analyze the dosimetric requirement tests.
Social changes, changes in spaces: what management strategy for cities;the case of the city of Laghouat(Algeria)
Authors: Abdellaoui  Abdelkader
Published: July 2022

With the communication highways, information begins, little by little, to escape from the traditional centers of political, military, business or even religious power. In society, which believes that it is gradually freeing itself from these powers, doubt is beginning to settle in, a number of questions arise, a new breed of commentators, youtubers, influencers, interpreters and preachers in all areas of social life that try to draw you into their context, their culture or their fashion. Moreover, the globalization of exchanges, relations, transportation tools, financial networks and marketing calls into question, implicitly and slyly, the concepts of State, Nation, Community, the very belonging of the 'Individual to a “group”, as part of a united Whole. The citizen is becoming more and more an individual connected to his telephone and isolated from the rest. But with the decrease in resources and the increase in constraints of all kinds, the people wonder about their past, their future, their present; the malaise it is going through. She wonders about the modes of governance that are imposed on her, about the many problems she faces daily and the solutions that we cannot offer her. She looks elsewhere and compares, compares herself to other societies and begins to dream, to hope and, very quickly, to express her anger. The viable geographical space which is shrinking from year to year, the anarchic and how rapid expansion of agglomerations, the resources which are running out are all sources of additional concern for societies which are looking for themselves and no longer find themselves in an organizational system they no longer understand, tossed as they are between a protective past, a tempting present and an elusive future. This article attempts, for the city of Laghouat, to identify the difficulties to be overcome for a new management of spaces and for societal education. He then proposes the implementation of a management strategy based on the creation of a complete database on the physical spaces, the infrastructures, the networks (including the urban transport networks) as well as the services involved in the day-to-day management of the city.

The dataset contains long gridded time series of monthly minimum, maximum and mean air temperature and atmospheric precipitation for Ukraine, covering the period of 1946-2020. The dataset was built through the thorough historical climate data processing, which included all mandatory steps: data rescue/digitization of missing values and/or periods in station time series from paper sources, their quality control and homogenization, and interpolation on 0.1x0.1 grid. The station data comprised monthly values of 178 stations for air temperature (for each of three parameters) and 224 stations for atmospheric precipitation. The quality assurance and homogenization were performed by means of the widely used homogenization software HOMER (HOMogEnization in R), while the well-known interpolation software MISH (Meteorological Interpolation based on Surface Homogenized data basis) was used to perform the gridding.
Hunger as a factor in the criminalization of Ukrainian society in 1932–1933 (on the materials of Dnipropetrovsk region)
Authors: Romanets Nataliia
Published: July 2022

The aim of the article: to analyze the criminogenic situation in the cities of Dnipropetrovsk region during the Holodomor of 1932–1933 and the measures of the regional authorities to combat crime. Methods: comparative-historical, problem-chronological, historical-genetic. Processing of archival documents are carried out using the methods of source studying and hermeneutic analysis. The scientific novelty of the article is that the author characterizes the criminogenic situation in the cities of Dnipropetrovsk region during the Holodomor of 1932–1933 and the measures of the regional authorities to combat crime for the first time. Practical meaning: the results of the research can be used for studying the socio-psychological consequences of the Holodomor of 1932–1933. The originality of the study is based on the identification and analytical and synthetic processing of previously unknown archival documents of the Dnipropetrovsk Regional Committee of the CP(b)U, Dnipropetrovsk Regional Police Department, Dnipropetrovsk City Prosecutor`s Office from the State Archives of Dnipropetrovsk region. Main results. It is shown that the main reasons for the increase in crime were famine and large-scale repression, which led to the emergence of the so-called declassed element – the peasants, deprived of livelihood. Thefts, robberies, fraud with grocery documents were the main types of crimes in cities during the Holodomor of 1932–1933. It was proved that the crime situation in the Dnipropetrovsk region remained difficult throughout 1933 despite the measures taken by the Soviet party leadership. The justice authorities and the GPU, created to fight the counter-revolution, were unable to protect the property and life of city dwellers. The ineffectiveness of fight against crime was determined by the authorities desire to eliminate the phenomenon without eliminating its causes. Іt was impossible to stop thefts, robberies, and murders of the urban population, since most of the thieves were “criminals of despair”. It was also impossible without stabilizing the food situation. Type of article: theoretical, research.

Authors: Sorokin Andrii , Strilets Vasyl
Published: July 2022

The aim of the article is to study prerequisites and formalization process of inter-municipal cooperation of Kyiv with Chicago and Toronto held in July 1991. Methods of research: historical-genetic, comparative historical analysis, historical-biographical, structural-functional. Main results. The Kyiv City Council and its executive committee senior officials regarded the establishment of twinning relations of Kyiv with two North American cities mentioned above as an important component of enhanced cooperation between the Kyiv City Council and the Ukrainian western diaspora. Contacts of Kyiv authorities with representatives of the Ukrainian western diaspora and American and Canadian officials in 1990 along with increasing costs for international links contributed to the intensification of preparations for the process of institutional twinning between Kyiv and two mentioned North American cities held in July 1991. The latter coincided with the 1st anniversary of the adoption of the Declaration of State Sovereignty of Ukraine and the 100th anniversary of the arrival of first ethnic Ukrainians in Canada. Institutional twinning between Kyiv and Chicago took place in the latter, whereas the same process between Kyiv and Toronto was held in the capital of the Ukrainian SSR; formalization of twinning between Kyiv and the named two North American cities involved Kyiv City authorities who were accompanied by the members of the Ukrainian western diaspora and senior officials representing the USA, Canada and the Ukrainian SSR. The signing of inter-municipal agreements of Kyiv with Chicago and Toronto led to additional meetings with the participation of authorities, highest officials and participants of public organizations of the Ukrainian western diaspora; twinning between Kyiv and Toronto was covered by Ukrainian newspapers better than the same process between Kyiv and Chicago. Practical meaning of the article consists in the possibility of using its conclusions for the further studies of the history of twinning of Ukrainian cities. Originality of the article lies in setting its goal and the combined use of domestic and foreign concrete historical sources. Scientific novelty of the article consists in the attempt of comprehensive investigation of establishment of twinning links of Kyiv with Chicago and Toronto based on a broad range of sources. Type of article: research.
Comparación de resultados quirúrgicos de artroscopías realizadas en pacientes con pinzamiento femoroacetabular tipo cam.
Authors: Valerio Bermúdez Arturo , Chaverri Esquivel Laura , González Fernández Jessica
Published: July 2022

Introducción: El dolor crónico de cadera es un síntoma que modifica la funcionalidad y la calidad de vida de las personas, una de sus principales causas es el pinzamiento femoroacetabular (FAI), el cual se clasifica en 3 tipos: pinza, cam y mixto, siendo el tipo cam o leva, la pérdida de la esfericidad de la cabeza femoral. Esta deformidad ósea se ha relacionado con la osteoartritis de cadera, debido a la degeneración del cartílago articular y lesión del labrum acetabular que provoca su pinzamiento constante. El objetivo de este trabajo fue realizar una revisión sistemática de los artículos científicos originales que indiquen diferentes técnicas quirúrgicas utilizadas en pacientes con FAI tipo cam o leva mediante un abordaje artroscópico para comparar los resultados obtenidos. Metodología: este estudio se realizó de acuerdo con las normas PRISMA 2020. La búsqueda fue realizada en el idioma inglés en PubMed, Science Direct y Google Scholar, utilizando femoroacetabular impingement, FAI, cam-type, arthroscopic y, arthroscopy como palabras claves. Resultados: Al realizar la indagación se obtuvieron un total de 57 registros, se seleccionaron tres para realizar la discusión. En estos se encontraron como abordajes la artroscopía y la cirugía miniabierta acompañada de artroscopía.  Discusión: Con ambos abordajes se obtuvo una reducción de la escala visual análoga del dolor y un aumento de la funcionalidad, independientemente del éxito o fracaso clínico de la misma. Presentando menos complicaciones posquirúrgicas la cirugía miniabierta. Ambos abordajes obtienen resultados consistentes a los obtenidos por la luxación abierta de cadera presentando menor morbilidad y una rehabilitación temprana. Siendo la cirugía abierta una opción para iniciar la curva de aprendizaje en cirujanos ortopedistas que realicen femoroplastías.
Fibrolamellar Carcinoma with DNAJB1-PRKACA Fusion in a 16-Year-Old: Case Report and Review of Literature
Authors: Prakash Varsha , Varshney Neha
Published: July 2022

Fibrolamellar hepatocellular carcinoma (FLC) is a unique primary liver malignancy arising in noncirrhotic livers of young adults with an incidence of 0.02 per 100,000 in the USA (1). In the 5th edition of the WHO classification of the digestive system tumors published in 2019, fibrolamellar carcinoma is categorized as a subset of hepatocellular carcinoma (HCC). In 2014, the unique DNAJB1-PRKACA chimeric fusion protein was identified. Later studies proved this chimeric fusion protein as the main pathological driver in the disease manifestation of fibrolamellar carcinoma. Despite the invention of specific molecular genetic alteration in FLC, its oncogenic role and implication in FLC treatment remain an enigma. Surgical resection remains the primary therapeutic option, and the recurrence rate is extremely high (1). We present a case of fibrolamellar carcinoma in a pediatric patient with the PRKACA rearrangement resulting in DNAJB1-PRKACA fusion.
Failure mechanism of geocell-reinforced vertical plate anchors subjected to lateral loading
Authors: Choudhary Awdhesh Kumar , Dash Sujit Kumar
Published: July 2022

This paper reports the failure mechanism of geocell-reinforced vertical anchors in sand through a series of tests and numerical analyses. It is observed that the anchor load-carrying capacity significantly increases with the application of geocell reinforcement, which is primarily associated with the rupture behaviour of reinforced anchor beds. The rupture surfaces are found to have originated from the bottom edge of the geocell mattress and propagated to the soil surface in a curvilinear shape. The size of rupture surface tends to increase with an increase in length, width and height of the geocell mattress leading to an increased load-carrying capacity of the system. However, beyond a certain length, width and height of the geocell mattress, further increase in size of the rupture surfaces was marginal. Geocells of relatively smaller pocket size (i.e. close to anchor size) can effectively confine the soil leading to a coherent structure that inhibits potential rupture close to the anchors. However, geocells with wider pocket openings enable rupture to occur within the geocell mattress. Hence, it is concluded that the load-carrying capacity of reinforced anchors that is dependent on the size of the rupture surface is influenced by the geometry of the geocell mattress.
Contrast Preservation in Mandarin R-suffixation: A comparative study of Beijing and Liaoning dialects
Authors: Fu Boer
Published: July 2022

Two dialects of Mandarin Chinese, Beijing and Liaoning, display different patterns in r-suffixation, a morphophonological process. This paper investigates the low vowel rhymes: /an/, /a/, /aŋ/ in the two dialects. In Beijing, /an/ and /a/ undergo neutralization with the addition of the diminutive /-r/ suffix (Zhang 2000). But in Liaoning, the two rhymes maintain their contrast in the suffixed forms by each employing a different /r/ allophone for the suffix. /an/ selects for the retroflex rhotic [ɻ], while /a/ opts for the non-retroflex, or bunched, [ɹ] in Liaoning. I present a contrast preservation analysis to account for the difference between the two dialects. The analysis is set in the framework of Flemming’s (1995) Dispersion Theory. It employs MinDist constraints and PreserveContrasts-BD, which is a modified version of Flemming’s MaximizeContrasts, adapted to refer to output-output mapping. I argue that the overarching objective for both dialects is to maintain salient contrasts between the suffixed forms, but they differ in whether they prioritize preserving the three-way contrasts of low vowel rhymes or maintaining enough auditory distance between the suffixed rhymes. Liaoning prioritizes preserving the three-way contrasts, ranking PreserveContrasts-BD alongside MinDist, whereas Beijing is less preoccupied with keeping three suffixed forms, ranking PreserveContrasts-BD below MinDist. This is why the contrast between /an/ and /a/ is preserved in Liaoning via /r/ allophony, but neutralized in Beijing. Acoustic evidence for the two allophones of the r-suffix is provided. Segmental processes involving the low vowel and the nasal coda are also discussed.
