The Relationship between Public Debt, Budget Deficit, and Sustainable Economic Development in Developing Countries: The Role of Corruption Control
This study investigates the effects of public debt and budget deficits on the sustainable economic development of developing countries, taking into account the role of control of corruption. The two-step GMM method was applied for unbalanced panel data of 59 developing countries from 2004 to 2015. The study found that public debt and the budget deficit had negative effects on sustainable development, while the effect of control of corruption was positive. Moreover, using interaction terms between control of corruption and public debt and budget deficit, respectively, empirical results showed that controlling corruption limited these adverse effects. Thus, if the objective is to achieve sustainable economic development, developing countries should not see raising public debt or maintaining budget deficits as a strategy for economic development. The study contributes empirical evidence to the theory of debt overhang, crowded effects, and institutional theory in the context of developing countries. The implications are also discussed in this paper
Pneumococcal infections and homelessness
Objectif. To assess the prevalence of pneumococcal nasopharyngeal carriage, the role of potential risk factors, and vaccination against invasive pneumococcal diseases (IPD) among sheltered homeless persons (HP) in Marseille, France.
Methods. In 2015–2018, we enrolled 571 sheltered homeless males and 54 non-homeless controls. Streptococcus pneumoniae was directly searched form nasal/pharyngeal samples using PCR.
Results. The HPs were predominantly middle-aged, mostly migrants originating from African countries. Pneumococcal vaccination rate was low (3.1%). The overall pneumococcal carriage rate was 13.0% and was significantly higher in HPs (15.3% in 2018) than in controls (3.7%), with p=0.033. Among HPs, being aged ≥65 years (OR=1.97, p=0.048), living in one specific shelter (OR=1.80, p=0.028), and presenting respiratory symptoms and signs at the time of enrolment (OR=2.55, p<10-4) were independent factors associated with pneumococcal carriage.
Conclusion. Pneumococcal vaccination should be systematically considered for sheltered HPs in France, as has been the case in Canada since 2008
Employment, Earnings and Social Protection for Female Workers in Vietnam’s Informal Sector
The informal sector plays an important role in employment creation and poverty reduction among female laborers in Vietnam. Currently, around 70 percent to 80 percent
of women in Vietnam work in the informal sector, of which about 60 percent are in the agriculture and 20 percent are in the non-agricultural sectors that are mostly affiliated
with small-size production and service units.
By investigating the employment, earnings, and social protection policy on female labor in Vietnam’s informal sector, this research is able to answer the following
research questions:
1) How important is the role of female labor in the informal sector?
2) What are the important factors that influence job opportunities for women in the informal sector?
3) What are the policy implications on female labor in Vietnam's informal sector?
4) What are the causes of work insecurities among females in Vietnam's informal sector?
5) What areas of social protection are most needed by women workers?
6) How does one address these principal needs for social protection among female workers

Climate Change Vulnerability Assessment for the Major Habitats and Species in Lung Ngoc Hoang Nature Reserve, Vietnamese Mekong Delta
The study assessed the vulnerability of habitats and species to climate change in Lung Ngoc Hoang Nature Reserve (NR), Vietnam. The vulnerability assessment tools for habitat and species were developed by the International Union for Conservation of Nature (IUCN). Community members, NR managers and experts in the fields of environment, economic and rural development were involved in this study. The results showed that saltwater intrusion and inundation could cause serious threats to habitats (i.e., open water, Lung, agricultural and Melaleuca habitats) and freshwater species. The combined impacts of drought and high temperature potentially increase forest fires for the Melaleuca habitat and decrease the quantity and quality of open water habitats. The Melaleuca and Lung habitats have a high baseline conservation status, in which Melaleuca habitats are more vulnerable than Lung habitats. Conversely, open water and agricultural habitats are at low baseline conservation status, but open water habitats are more vulnerable. In addition, the proliferation of invasive alien species, encroachment on agricultural cultivation, and the degradation of water quality are also great threats to the NR. Key species, including Melaleuca cajuputi, Elaeocarpus hygrophilus, Chitala ornate, Channa micropeltes, were at low threat of climate change. However, C. ornate and C. micropeltes are seriously endangered by seawater intrusion, drought and poor water quality. The findings of this study can provide essential information for NR managers to formulate water management plans for the protection and management of the habitats and species in Lung Ngoc Hoang NR
Usporedba enzimske i ultrazvuÄŤne ekstrakcije albumina iz praha kondicioniranih sjemenki bundeve (Cucurbita pepo)
In this study, ultrasound- and enzyme-assisted extractions of albumin (water-soluble protein group) from defatted pumpkin (Cucurbita pepo) seed powder were compared. Both advanced extraction techniques strongly increased the albumin yield in comparison with conventional extraction. The extraction rate was two times faster in the ultrasonic extraction than in the enzymatic extraction. However, the maximum albumin yield was 16 % higher when using enzymatic extraction. Functional properties of the pumpkin seed albumin concentrates obtained using the enzymatic, ultrasonic and conventional methods were then evaluated. Use of hydrolase for degradation of cell wall of the plant material did not change the functional properties of the albumin concentrate in comparison with the conventional extraction. The ultrasonic extraction enhanced water-holding, oil-holding and emulsifying capacities of the pumpkin seed albumin concentrate, but slightly reduced the foaming capacity, and emulsion and foam stability.U ovom su radu uspoređena dva postupka izolacije albumina, proteina topljivog u vodi, iz praha kondicioniranih sjemenki bundeve (Cucurbita pepo), i to ekstrakcijom pomoću ultrazvuka te pomoću enzima. U usporedbi s konvencionalnom ekstrakcijom, oba su postupka znatno povećala prinos albumina. Ultrazvučna je ekstrakcija bila dva puta brža od enzimske, međutim, najveći je prinos albumina od 16 % dobiven enzimskom ekstrakcijom. Ispitana su funkcionalna svojstva koncentrata albumina dobivenog iz sjemenki bundeve enzimskom, ultrazvučnom i konvencionalnom ekstrakcijom. Enzimska hidroliza nije utjecala na funkcionalna svojstva koncentrata albumina, za razliku od konvencionalne ekstrakcije. Ultrazvučnom su ekstrakcijom poboljšana svojstva zadržavanja vode i ulja te emulgiranja, a neznatno smanjena svojstva pjenjenja te stabilnost pjene i emulzije koncentrata albumina
Application of satellite images and VNREDSAT-1 images in study on marine environment in Truong Sa region
The remote sensing images, including images of MODIS, VNREDSAT-1 and altimeter, are applied for researching marine environment with the different resolutions. On the basis of different time remote sensing images, we concentrated on the assessment of several characteristics including the SST, chlorophyll-a concentration and sea surface current at the different depths in different monsoons as well. With the large areas, we used the images of MODIS and altimeter. The detailed research area focuses on the Nam Yet island, and the images of VNREDSAT-1 are used. The analysis method of environmental parameters of SST and chlorophyll-a used the regression functions based on the single and combined bands to enhance the accuracy of the analysis result. The marine parameters collected at different depths in the latest field surveys on Truong Sa archipelago in the years of 2015 and 2018 are presented in this paper. On the basis of these parameters, we can analyse the relationships and compare the real field survey data and corresponding results interpreted from remote sensing images
