PO 18035 - Metatarsophalangeal arthrodesis for hallux valgus treatment
Authors: Veiga Sanhudo José Antônio , Barbosa Horta Barbosa Luiza
Published: November 2019

Introduction: Hallux valgus is the most common deformity of the adult foot and is often highly debilitating, especially when severe. First metatarsophalangeal arthrodesis (FMTPA) is a reliable method of hallux valgus correction, with a high success rate and a low relapse rate. This study assesses the union rate and degree of satisfaction and compares the pre- and postoperative American Orthopedic Foot and Ankle Society (AOFAS) scale scores of patients subjected to FMTPA for hallux valgus treatment. This study is a retrospective review of 29 feet that underwent FMTPA fixed with crossed 1.5-mm Kirschner wires, with or without cerclage. Union was assessed radiologically and clinically. Methods: From March 2011 to April 2018, 23 patients diagnosed with hallux valgus underwent surgery using the FMTPA technique fixed with crossed Kirschner wires. One patient died of unrelated causes, and another was not located for the review, leaving a total of 21 patients for the analysis (29 feet). Eight patients were operated on bilaterally, 6 underwent operation of the right foot, and 7 underwent surgery of the left foot. The mean follow-up was 32 months (7-94 months), and the mean age at the time of surgery was 69 years (45-88). Results: The AOFAS score improved from a mean of 26.8 points before the surgery (10-55) to a mean of 77.6 points after (57-90). The patients were fully satisfied with 17 of the 29 procedures and satisfied with reservations in 12 cases. No patient was dissatisfied with the outcome. Clinical and radiological union was observed in all cases. The orthopedic hardware was removed due to pain or local discomfort in 18 feet (62% of cases). Conclusion: FMTPA fixed with crossed Kirschner wires for hallux valgus treatment is highly effective, with a high union rate and a high degree of patient satisfaction.

Published: November 2019

Introduction: The os peroneum is a round or oval sesamoid bone located distally within the substance of the peroneus longus tendon near the cuboid bone. Peacock et al. suggested that the presence of the os peroneum might be associated with tendon rupture due to friction at the junction with the bone; in turn, Brigido et al. developed radiographic criteria that associate sesamoid fracture with mechanical failure of the peroneus longus tendon. Objective: To report an unusual case of peroneus longus tendon injury associated with the presence of os peroneum in a patient with hindfoot varus. Methods: A 55-year-old male patient who engaged in physical activity 3 times a week developed pain on the lateral side of the ankle resulting in decreased physical functioning and sports performance. Radiography showed the presence of os peroneum associated with a proximal injury of the peroneus longus tendon detected by magnetic resonance imaging. Results: The patient was treated conservatively with an analgesic physical therapy program followed by functional rehabilitation. The patient progressed from a score of 9 on the visual analog scale for pain in the first month to a score of 0 at 6 months, with grade 5 final eversion force and a return to sports performance at the preinjury level. Conclusion: Treatment options for this injury range from tendon debridement, fixation or excision of the os peroneum to tenodesis or tendon anchorage to the cuboid or calcaneus. Nonsurgical treatment, including immobilization and the use of anti-inflammatory medication, followed by physical therapy is the initial treatment of choice and, as in the reported case, may provide an excellent outcome.

Published: November 2019

Introduction: The extremely high prevalence of sprains in the population has led to a large number of patients with lateral ankle instability. The persistence of this condition can lead to progressive loosening of the medial containment structures, generating multidirectional rotational instability. Treatment of the deltoid complex through ligamentoplasty of its components has been proposed as a solution for these patients, and the arthroscopic technique is a currently described alternative. Methods: This is a retrospective study of 10 patients (11 ankles) diagnosed with multidirectional instability who underwent ankle arthroscopy with medial and lateral ligament reconstruction (arthroscopic Brostrom technique) from January 2017 to January 2019. All patients filled out an epidemiological questionnaire and were assessed for ankle pain and function using the Pain Visual Analog Scale (VAS) and the American Orthopedic Foot and Ankle Society (AOFAS) scale at the last follow-up evaluation, at a mean of 12 months (6-24 months). Results: All patients showed signs of associated medial instability during the arthroscopy. Four ankles had associated osteochondral injuries. One ankle also had associated syndesmotic instability. The mean AOFAS score was 82.6 at the last follow-up evaluation, and the mean VAS score was 2.1. No patient had complications related to surgery or loss of ankle mobility greater than 5 degrees (ankle or subtalar joint). Eight patients described the outcome as excellent, and 2 described it as good. All patients returned to sports after 6 months of follow-up. No complaints of instability or positive ligament tests were observed. Conclusion: Combined medial and lateral arthroscopic ankle ligamentoplasty is an effective and safe alternative for the treatment of multidirectional instability refractory to conservative treatment. The inclusion of the deltoid complex and the reduced invasiveness of this technique may improve the clinical outcomes of these patients.

Authors: Christovan Ribeiro Evandro Junior , Damião Prata Sérgio , Rizzo Marco Antônio
Published: November 2019

Introduction: Ankle fractures account for 10% of all fractures and rank second in frequency among lower limb fractures, behind only hip fractures. The lack of studies on the epidemiology of ankle fractures available in the Brazilian literature motivated a more in-depth study to better describe these fractures. The objective of this study was to analyze the epidemiological characteristics of ankle fractures. Methods: An epidemiological, prospective, descriptive, observational study of ankle fractures in a convenience sample taken from the study hospital. In total, 150 patients were evaluated from March 2016 to March 2017. A questionnaire was prepared to collect patient data and variables for subsequent analysis. The following parameters were analyzed: age, occupation, sex, ethnicity, marital status, education, emergency transport, time of trauma, day of the week of trauma, trauma mechanism, fracture type, affected limb, classification, treatment, associated injury and length of hospital stay. Results: Among the patients with ankle fractures, 33.66% of the fractures occurred in the afternoon. A total of 61.34% of the ankle fracture patients were men, and the right was the most commonly affected side. The mean age was 40.48 years. The most frequent trauma mechanism was fall from height, which accounted for 51.42% of fractures. Weber type B fractures were the most frequent type. Conclusion: Ankle fractures treated at the Department of Orthopedics and Traumatology during the study period primarily affected married, Caucasian patients aged between 40 and 50 years with up to a primary education level; fractures were most frequently on the right side and primarily occurred in the afternoon and on Sundays. Sprain due to fall from height was the most common trauma mechanism, and exposed fracture occurred in 28% of the cases.
PO 18122 - Treatment of Charcot arthropathy in the ankle joint
Authors: Cursino Fernandes Milena Peloggia , De Marchi Neto Noé , Cardenuto Ferreira Ricardo , Tulio Costa Marco , Bergamasco Jordanna , Gobbo Daiana
Published: November 2019

Introduction: Charcot arthropathy can lead to joint destruction and often causes ulcers at sites of bony prominences. In the ankle, it causes instability that limits gait and makes it difficult for patients to wear shoes or orthoses. This was a retrospective study describing cases of Charcot arthropathy of the ankle treated at our institution from 1997 to 2017. Methods: Over the study period, we treated 252 patients with Charcot arthropathy. Of these patients, 27 presented the disease exclusively in the ankle. The selected cases were unilateral; 17 of the patients were men, and the mean age was 55 years. Nine patients were treated conservatively, and 18 were treated surgically to stabilize the ankle (including the hindfoot, if necessary). During surgery, different fixation methods were used depending on the presence or absence of ulcer at the time of the intervention. At the end of the treatment, we assessed the patient’s ability to wear shoes or orthoses for walking, the stability of the ankle joint and, in surgical cases, union. We considered a good outcome when the patient was able to walk wearing shoes or orthoses, and the limb was stable; an acceptable outcome when the limb was unstable, but the patient adapted to orthoses; and a poor outcome when the patient was unable to walk, and the ankle was unstable or amputated. Results: Nine patients underwent conservative treatment using total contact casting at the initial phase of the disease, followed by orthosis after union. Of these patients, the outcome was poor for 5, good for 3 and acceptable for 1. Eighteen patients underwent reconstructive surgery; 12 patients had a good outcome; 2 patients underwent amputation, and 4 patients had unsuccessful surgeries. Conclusion: Charcot arthropathy of the ankle causes considerable instability. Conservative treatment of the disease fails to provide good outcomes, and the patients who underwent reconstructive surgery had the best functional and clinical evaluations.

Authors: De Brito Teixeira Marcelo , Souza de Albuquerque Gabriel , Souza Lima Segundo Clauser Roberto , Rodrigues Santos Carneiro Felipe , De Souza Guimarães Janice , Mota Garcia Moreno Marcus Vinícius
Published: November 2019

Objective: To demonstrate the patterns of syndesmosis reconstruction in ankle fractures via the measurement of pre-established and universally accepted parameters. Methods: In a retrospective study, fractures with radiographic images obtained during the postoperative period and showing fixation of the distal tibiofibular syndesmosis were selected. Fracture reduction and syndesmosis fixation were evaluated by measuring radiographic parameters in the selected cases. Results: Twenty-three patients (63.8%) were male. Fourteen fractures (38.8%) were operated on by a senior surgeon (foot and ankle specialist). All syndesmoses were fixed with only one screw, and 35 patients (97.2%) had syndesmosis fixation involving 3 cortices. The mean syndesmosis fixation height from the articular surface was 2.20 cm. Four fractures (11.1%) presented radiographic signs of medial ligament reconstruction. Regarding the measurement of the tibiofibular space, in the anteroposterior (AP) view, 33 patients (91.6%) had values within the normal range. Regarding the tibiofibular overlap, in the AP view, 19 patients (52.7%) had measurements with values greater than 10 mm (normal). In the evaluation of tibiofibular overlap, in the true anteroposterior (AP) view, all patients (100%) presented measurements greater than 1 mm (normal). Regarding the measurement of the talocrural angle, only 1 patient did not have normal parameters. Regarding the medial clear space, only 2 patients (5.5%) had values above normal during the postoperative period. Conclusion: The adoption of objective, standardized parameters relative to the contralateral side adds value to the evaluation and ensures an accessible and reproducible method for evaluating syndesmotic ankle fractures.
Low terraces of the Styr River valley in the middle part of the Volhyn Upland
Authors: Hnatyuk Roman , Novak Taras
Published: November 2019

The paper focuses on the description of the low Pleistocene terraces (with the height of up to 20 m above the river level) of the Styr River valley that were identified in the middle part of the upland between Bilche–Krasne villages in the south and Boratyn–Pidhaitsi villages in the north. The main attention is concentrated on the mapping of the terraces and the overview of their outcrops as well as analysis of the boreholes data. The study of the geological structure of the terraces becomes the basis to determine their age.
Mapping of river terraces was executed using topographic maps in scale 1:10 000. On the territory where previous researchers identified one or two terraces, we have identified five morphologically distinct cyclic (paired) terraces. The highest low terrace that is widespread territorially is named here the main terrace and the other four that are locally preserved are combined in a complex of minor low terraces.
The level of the main Styr terrace has almost constant altitude of about 191–192 m. The average height of the terrace surface is gradually increasing downstream from 12–13 to 14–16 m above river level. Its surface is slightly undulating and complicated by relatively large isometric depressions with the diameter of up to 100 m and more. The slightly meandering forms similar to channels with the plan size comparable with the modern Styr channel occur on the terrace surface. The main terrace is relatively complicated and has mainly two-termed structure – the lower part of sedimentary sequence is composed of normal (perstrative) alluvium of large thickness; the upper part is composed of constrative alluvium accumulated when the river channel was laterally inactive. The terrace is overbuilt by a loess layer a few meters thick that covers floodplain alluvium without a distinct break in accumulation. Geological structure of the minor low terraces is relatively simple and recalls the floodplain structure. Absence of well-expressed paleosols in the alluvial and loess deposits of the low terraces suggests that they were formed during Late Pleniglacial (MIS 2).
Key words: river terrace, alluvium, Late Pleistocene, Late Pleniglacial, Volhyn Upland, Styr River valley.
Territorial and political development of independent Ukraine: Long-standing problems and new challenges
Authors: Dnistryanskyy Myroslav
Published: November 2019

The concept of territorial and political development is exposed. The trends of the dynamics of regional differentiation of the electoral and political activity of citizens of Ukraine for the entire current period of its independence, main regional and political problems are identified. It is concluded that the at the first stage of territorial and political development (1991–2000 years), despite widespread Soviet identity and significant differentiation of mental and political moods, preconditions for interregional rapprochement or understanding though slowly formed, the issue of including Crimea into the legal field of Ukraine is solved. Territorial and political development of Ukraine in the direction of conflict was oriented since 2000, as a result of the mobilization of pro-Russian forces by the leadership. It appeared in the polarization of electoral and political attitudes, expanding the range of openly anti-Ukrainian political organizations, imposing the federal organization for Ukraine. Prospects for sovereign territorial and political development of Ukraine aggravated when in 2010 Russia continued to stay the Black Sea Fleet in the Crimea, and actually took control of the state security forces. Russia has moved to the open annexation of Ukrainian territories in the spring of 2014, occupying Crimea and Donetsk region that marked a new phase of territorial and political development of Ukraine. It is the restoration of the sovereignty and political integrity, countering Russian aggression and its attempts to destabilize the situation in other regions are the main challenges facing Ukraine at present.
Key words: territorial and political development, regional and political issues of Ukraine, electoral geography, regional polarization of political attitudes, regional separatism.
Implementation of the methodological mechanisms for evaluation of the sustainable development in towns
Authors: Zhuk Yuriy
Published: November 2019

The need to move on the path of sustainable development is actively discussed in academic and government circles for four decades. During this time the own national concepts and methods of evaluating of the sustainability were created, both in developed and developing countries. In some cases, the number of indicators was calculated by the hundreds. Government authorities began to pay attention to issues of analysis of the sustainability but the problem is that not all the developed techniques are suitable for the practical use due to lack of the sufficient statistical data used in the calculations. It is necessary to highlight the lack of a unified methodology for evaluation of the sustainability that makes it difficult to analyse both global and regional trends and the lack of a systematic approach to the techniques analysis. The concept of sustainable development and its dimensions (economic, ecological and social) are considered in the article. Approaches to evaluating sustainable urban development, particularly at the national level are analysed. The performance indicators, indexes structures of economic, environmental and social dimensions are proposed. Based on the initial data, integral index and the degree of harmonization of sustainable development of ten small towns of Lviv region were calculated. Key words: town, sustainable development, the dimensions of the sustainable development, degree of the harmonization.

Authors: Kiptach Fedir , Koynova Iryna
Published: November 2019

The large-scale landscape maps necessity in developing projects and proposals for agriculture, forestry land-use and erosion protection were justified. Natural conditions of land-use in Nova Syniava community in Stara Syniava district in Khmelnytskyi region were described and analyses of land structure were made. Accordingly, land structure is characterized by ecologically destabilizing lands, including arable lands, lands that were withdrawn from agriculture production and forestry (outbuildings, houses, roads, open-casts, exterior use lands) are prevailing. They cover 80,6 % (in particular, arable lands – 71,8 %) of total community lands. And, vice versa, ecologically stabilizing lands (gardens, pastures, grasslands, shrubs, forest belts, forests, swamps, water covered lands) cover a small percentage – 19,4 of total research area. Therefore, erosive soils cover a significant percentage – 51,3 % of total area. Soil erosion caused decreasing of soil fertility and yields of agriculture. The average weighted losses of humus in arable horizon of soils (0–30 cm) compared with full-profile standard analogues are 0,5–0,6 %. First step of developing sustainable ecological landscape systems were justified by using a principle of land resource restoration and strengthening of their self-regulation through increasing the area of ecologically stabilized lands by low productivity lands and by their location with taking into consideration a complex morphological structure of landscape systems. Landscape systems of research area were classified by genesis and type of their economic use. Arable lands should cover no more than 52,4 % of the total community area. In particular, 16,1 % is recommended to use for field grain-steam tilled crop rotations and cultivating all agriculture crops of this zone by using intensive agriculture systems and the widespread introduction of their ecological links; 27,9 % is recommended to use for field grain-steam tilled crop rotations and cultivating all agriculture crops of this zone by using ecological systems of agriculture provided soil cultivation, sowing and caring for crops according to the elevation line directions. 8,4% is recommended to use for field grain-grass or grass-grain soil protected crop rotations with total exclusion of row crops. 38,8 % of total community land area should be covered by perennial plants (6,6 %), grasslands (17,0 %), shrubs and forest belts (0,31 %), forests (11,7 %), swamps (1,09 %), lands covered by water (1,2 %). Other 8,8 % are covered by outbuildings and houses (1,2 %), roads (2,0 %), opencasts (0,8 %) and exterior use lands (4,8 %). Key words: forest steppe, landscape systems, land-use, lands, crop rotations.

Authors: Kozak Ihor , Kozak Hanna
Published: November 2019

The study was conducted within the actual area of Lutoviska commune in Bieszczady district, Podkarpackie voivodeship in Eastern Poland. The dynamics of settlements in Lutoviska commune from the 2nd half of the 18th century was discussed. Maps and historical data were analyzed in the ArcGIS 10.3 program. In the study there were presented possibilities of applying the ArcGIS for Desktop 10.3 program. We analyzed the Lutoviska commune in terms of the changes of settlements and used maps for the analysis of changes in its structure. The first of these was the historical map, namely the tactical map of “WIG” in scale 1:100 000 from 1936. Next we analyzed maps from 1965 and 2014, which were prepared applying the “WMS” server. The changes in the number of villages and households were presented. Population dynamics for Greek-Catholics, “Latynnykys” and Jews for the year 1785 and Ukrainians in comparison with the number of Poles and Jews for the year 1939 were shown. Ethnic and religious composition from the 2nd half of the 18th century was evaluated. Based on the study of spatial placement of settlements with the use of Spatial Statistics (Spatial Autocorrelation Global Moran’s test, Standard Deviational Ellipse and Mean Centre) the character of settlements distribution in Lutoviska commune was presented. There was confirmed a similar configuration of Standard Deviation Ellipse and Mean Center for Greek-Catholics-Ukrainians in 1785 and Ukrainians in 1939 in Lutoviska commune. The scale and results of such changes are interesting for future research, mainly in terms of the change of traditional village system infrastructure and culture. Key words: dynamics, village, GIS, Lutoviska commune.
Hydrologic aspects of drained peatland renaturalization
Authors: Mykhnovych Andriy
Published: November 2019

The peatland drainage is one of the main man-made factors of the landscape water circulation and peatland ecosystems degradation. To return former sustainable ecological state of peatland it is necessary to carry out the renaturalization. The essence of renaturalization is renewal of water regime with following renewal of the peatland ecosystem like it was before drainage. Change of water runoff regime is effective mechanism of the peatland renaturalization – so called active protection. To renaturalize the Zalyvky peatland in the Roztochia Natural Reserve it is necessary to keep high groundwater level that will cause renewal of peat forming, stop succession processes, growing up by untypical for peatland plant species, reduce the risk of peat burning. Based on the results of natural conditions and recent ecological state of the Zalyvky peatland analysis the general scheme of renaturalization and hydrologic regime renewal has been worked out. With this aim, the series of measures are realized. They allow increasing the groundwater levels due to coming of water from the river streams and channels, making the runoff slower and renewing small water bodies. Small water bodies like ponds play not only water regulating role but also key ecological role for many bird species, ecological education, and tourist-recreation attractive. It is expected that keeping of higher ground water levels will be assisted by the beavers population with their natural dams. Key words: renaturalization, drainage melioration, peatland, water runoff regulating.

Stages of suspended soils formations in Verkhovyna dividing range of Ukrainian Carpathians
Authors: Pankiv Zinovii , Yavorska Andriana
Published: November 2019

It was found out that suspended soils in Verkhovyna Dividing Range in Ukrainian Carpathians are intrazonal ones and are formed near dense sandstones outcrops in Krosnenska zone provided excess moisture of flushing type of water regime. Suspended soils are located within the mountain-forest and subalpine zones under moss lichen communities. They form habitats ranging from 0.1 to 1.0 square meter, oval and oblong shaped with the highest capacity of organic horizon in the central part with gradual reduction to the periphery. Suspended soils in Ukrainian Carpathians were mentioned for the first time in writings of Professor A. Zrazhevskyi. Formation of suspended soils in dense sandstones within Verkhovyna Dividing Range can occur in two ways: initial (primary) soil development and settlement of moss lichen communities from adjacent soil areas. Main stages of formation of soils under research are detected analyzing the succession of plant communities and morphological features of each section. Initial stage begins with the settlement of alga, bacteria, fungi, actinomyces, lichens (crustose and foliose) in centres of soil formation and formation of humified layer of dark gray colour up to 2 cm thick. Moss settlement on the developed organo-mineral layer and formation of organic (peat) horizon marks the beginning of development stage. Soils under research with formed organic horizon up to 10 cm thick are to be classified as initial suspended soils. The development stage is accompanied by accumulation of defunct organic remains (peat formation) and expansion of organic horizon (Td+T). Soils formed in Krosnenska zone in mild wind-blown sandstones with organic horizon more than 10 cm thick are at the stage of equilibrium functioning. It is advisable to define these soils as peat-suspended soils. Suspended soils are not represented in the nomenclature list of soils of Ukraine, that encourages conducting more detailed research on their classification. Patterns of distribution of soils under research and stages of soil formation were found out. Key words: Verkhovyna Diving range, suspended soils, the formation of peat, genesis, stages of soil formation.
Haplic chernozems humus condition of Western Bug and Styr terraced landscapes
Authors: Papish Pavlo , Ivanyuk Halyna , Papish Ihor
Published: November 2019

Volyn Upland Haplic Chernozems are distributed mainly on the terrace landscapes of the Western Bug and the Styr and their tributaries (Chornohuzka, Luha, Lypa). Most of these soils are old ploughlands that have experienced various types of degradation. Haplic Chernozems are low-humus soils and they have low storages of humus substance in the 20 cm arable layer and middle storages of humus in 100 cm soil thickness. There is correlation of C humic acids to C fulvic acids within 1.2–3.3 in the humus profile. Among the various fractions of humic substances the 2nd fraction associated to Calcium dominates. A content of “free” humic acids (1rst fraction) is very low and the amount of humin is low. The optical density of humic acids ( 0,001% НА Е1 cm, 465 nm ) are high and very high. The organic matter of Volyn Upland Haplic Chernozems has some regional peculiarities. First, it caused by topographical conditions of its formation and evolution in the Holocene. Chernozems of the 1st terrace of the River Western Bug are extremely deep. They have progressive-accumulative type of humus distribution in profile, humate type of humus in upper 100 cm layer, a very high degree of organic matter humification and the same content of humic fraction associated to Calcium and lowmiddle content of 3rd fraction associated to clay minerals. The molecules of humic acids in the humus horizon of Chernozems of the 1rst terrace are better structured that indicates the older age of humus in these soils. Chernozems of the 2nd terrace above the floodplain of the River Styr are middle-deep soils. They are characterised by the regressive-accumulative type of humus distribution in profile, humate-fulvate type of humus and very high degree of organic matter humification only in 25–50 cm layer. The content of fractions associated to Calcium and clay minerals is predominantly high. Key words: Haplic Chernozems, humus, humic acids, fulvic acids, optical density, humus condition.

Comparative views on research productivity differences between major social science fields in Vietnam: Structured data and Bayesian analysis, 2008-2018
Authors: Vuong Quan-Hoang , Ho Tung Manh , Vuong Thu-Trang , La Viet-Phuong , Nguyen Minh-Hoang , Ho Manh-Toan
Published: November 2019

Since Circular 34 from the Ministry of Science and Technology of Vietnam required the head of the national project to have project results published in ISI/Scopus journals in 2014, the field of economics has been dominating the number of nationally-funded projects in social sciences and humanities. However, there has been no scientometric study that focuses on the difference in productivity among fields in Vietnam. Thus, harnessing the power of the SSHPA database (http://sshpa.com/), a comprehensive dataset of 1,564 Vietnamese authors (854 males, 705 females) with 2,410 publications in the 2008 – 2018 period was extracted and analyzed. Various factors were considered including age, gender, new authors, leading authors, co-authorship, and Impact Factor. The findings suggest a high level of contribution from authors at the age of 40 – 44 in economics (858 publications) in a 12-years period, which is equivalent to the social medicine total output, and two times more than the total output of the education. Moreover, the presence and reinforcement of male researchers are still dominating in Economics and other fields, with the only exception of education. Despite the rapid rise in the number of Vietnamese lead authors, gender disparity among disciplines is an issue. Contrary to the strong international collaboration-oriented tendency in social medicine, economics, and other fields, educational authors are not open to international collaborating. Finally, most of the publications in economics belong to the group with JIF from 0 to 2, in contrast with the high number of social medicine publications with JIF from 2 to 5, which suggesting the field of economics is fulfilling the quantity, but still, need more quality publications.
Defaultable Swap Valuation Framework
Authors: Xiao Tim
Published: November 2019

This paper presents a pricing framework for valuing interest rate swap subject to counterparty credit risk of both parties. Unlike structural models, reduced-form models do not condition default explicitly on the value of the firm, and parameters related to the firm’s value need not be estimated to implement the model. For pricing and hedging, reduced-form models are the preferred methodology. The closed-form solution gives us a better understanding of the impact of the credit risk on swap value, credit value adjustment, swap rate and swap spread.

Women's experience of child death over the life course: A global demographic perspective
Authors: Alburez-Gutierrez Diego , Kolk Martin , Zagheni Emilio
Published: November 2019

The death of a child affects the well-being of parents and families worldwide but very little is known about the scale of this phenomenon. We provide the first global overview of parental bereavement, its magnitude, prevalence, and distribution over age, for the 1950-2000 annual birth cohorts of women using a novel methodology from formal demography applied to data from the 2019 Revision of the United Nations World Population Prospects. We project that the global burden of parental bereavement will be 1.6 times lower for women born in the year 2000 than for women born in 1955. Accounting for compositional effects, we anticipate the largest improvements in regions of the Global South where offspring mortality continues to be a common life event. The paper quantifies an unprecedented shift in the timing of parental bereavement from reproductive to retirement ages. Starting with the 1985 cohort, women will be more likely to lose an adult child after age 65 than a young child before age 50, reversing a long-standing global trend. "Child death" will increasingly come to mean the death of adult offspring. We project persisting regional inequalities in offspring mortality and in the availability of children in later life, a particular concern for parents dependent on support from their children after retirement. Nevertheless, our analyses suggest a progressive narrowing of the historical gap between the Global North and South in the near future. These developments have profound implications for demographic theory, and highlight the need for policies to support bereaved older parents.

Florida’s latest Minimum Wage Initiative (Initiative #18-01) ishighly likely to appear on November’s voting ballot. This amendment proposesraising the current minimum wage of $8.46 to $10.00 per hour beginningSeptember 30th, 2021. Each year following the initial increase, theminimum wage would increase another $1.00 per hour until it reaches the goal of$15.00 per hour by the year 2026, which is marked by the dotted red line in Figure1. Based on this information, the Florida Legislature has tasked AERG with amulti-stage economic analysis that involves estimating employment effects,as well as tax revenue and social services expenditures.
Analysing the social network of technology and information transfer for maize sheller service providers in Zimbabwe
Authors: Chikutuma Mutsvandiani
Published: November 2019

Smallholder farmers and their households in Zimbabwe depend on maize as a staple food and source of income. despite the high demand for maize production, there is little service provision particularly shelling on post-harvest technologies. Therefore, service providers for maize shelling are suggested to have a strong social network with customers and other service providers for demand creation. The aim of the project was to understand the business approaches of the service providers and their performances, using SNA to track the use of shellers for service provision and the associated information network in Domboshava and Makonde districts, Zimbabwe. SNA through interviews were used to assess the demand for shelling through customer and non-customer characteristics, to identify demand creation approaches and to analyze how the communication network differs between service providers. There was a variation in total earnings on average Makonde service providers with more earnings than in Domboshava. Service providers obtained the customers based on trust from the community. Total earnings increased with increasing number of customers (p<0.001), higher degree centrality and shelling capacity for both districts. Network density was higher in Domboshava than in Makonde district indicating more frequent contacts in Domboshava. Despite the earnings, most of the service providers operated below full capacity due to the low maize production caused by drought and the late availability of shelling services to the farmers. The service providers that achieved higher turnovers, tended to have shelling machines with higher capacities compared to those operating with small shelling capacities. Service providers started their business in 2016 season and little promotion had been made amongst farmers for shellers’ awareness campaign. There is more urgent need for promotion and business development and upgrading of shelling capacities to boost business performance. Identification of central actors such as the agricultural extension officers is vital in the social network for dissemination of information for high uptake of services.
