Opis:
This article analyzes the challenges to American hegemony in the contemporary world order. It will demonstrate that the rise of the rest including China and India, the possibilities of a massive military attack and an economic collapse on American soil are merely exaggerated challenges to American hegemonic position. The challenges that have great potential to cut into American hegemony are very internal including American domestic and psychologic problems. Looking at the future of American hegemony, the article highlights that the United States still has overwhelming power to sustain its hegemony in the foreseeable time. Yet it is crucially important for American leaders to realize and effectively deal with the imminent challenges to its power. Also, six policy recommendations are made for the United States to endure its hegemony in the contemporary world order.

The Provincial Competitiveness Index is an indicator to evaluate and rank the governments of provinces and cities of Vietnam in terms of the quality of economic governance and building a favorable business environment. This is a measure of the level of local competitiveness in attracting and supporting development investment enterprises in a province. In recent years, localities have had many changes in policies and mechanisms, creating a strong attraction for investors, especially FDI. This plays an important role in promoting the development of local socio-economic sectors. The provincial government has been making great efforts to improve the business environment, creating favorable conditions for businesses and investors in the area. Therefore, many provinces and cities have risen to the top among localities in attracting investment, especially FDI. These successes have brought researchers, organizations at home and abroad to pay attention to the role of the provincial level, but more specifically the provincial competitiveness in Vietnam. Therefore, the study of provincial competitiveness index is not only aimed at promoting the development of the economy in general, but also contributes to exploiting the strengths of regional, sectoral and inter-regional relations. local in the development process.

Opis:
The paper presents the problem of omnichanneling technology acceptance by consumers in the purchasing process. The omnichanneling technology is an innovative solution used by retailers operating both brick&mortar and online retail formats, consisting in the integration of sales channels which aims to deliver a seamless customer experience regardless of the channel. It is an expensive and operationally complex solution, hence the need to test customer willingness to accept it. The objective of the article is to examine the determinants of both the intentions of acceptance the omnichannel technology by consumers and its use in purchasing behavior in accordance with the adopted UTAUT2 model. Methods: The work uses a hypothetical-deductive scientific method. Based on the UTAUT2 model, hypotheses were formulated regarding the type and strength of the latent variables impact on intention to accept technology and technology acceptance. Results: Data were collected from 280 respondents using CAWI method. Then, the factors were verified by exploratory factor analysis. Confirmatory factor analysis was used to examine the determinants (and the strength of their impact) of the intention to accept the technology and its use in the purchasing process. Conclusions: The research identified personal innovatinveness as the strongest predictor of omnichannel purchase intention, accompanied by social impact and expected performance. It was also found that perceived risk and hedonic motivation were not relevant in this study. The habit was proved to be a reliable indicator of both the intention to accept omnichanneling technology in the purchasing process and the behaviour associated with using the technology, while the facilitating conditions turned out to be related only to the use of omnichanneling technology.
W pracy przedstawiono problem akceptacji technologii omnichannelingu przez konsumentów w procesie dokonywania zakupów. Technologia omnichannelingu jest innowacyjnym rozwiązaniem stosowanym przez detalistów wykorzystujących zarówno stacjonarne, jak i internetowe formaty handlu, polegającym na integracji kanałów sprzedaży. Jest to rozwiązanie kosztowne oraz złożone operacyjnie, stąd konieczność zbadania skłonności nabywców do jej akceptacji. Celem artykułu jest zbadanie uwarunkowań zarówno intencji przyjęcia technologii omnichannel przez konsumentów, jak i jej wykorzystania w zachowaniach zakupowych zgodnie z przyjętym modelem UTAUT2. Metody: W pracy zastosowano hipotetyczno-dedukcyjną metodę naukową. Na podstawie modelu UTAUT2 zostały sformułowane hipotezy dotyczące rodzaju i siły oddziaływania zmiennych latentnych, do weryfikacji których zastosowano konfirmacyjną analizę czynnikową. Pozwoliła ona wskazać determinanty i określić siłę ich wpływu zarówno na intencję akceptacji technologii omnichannelingu w procesie zakupu, jak i jej użycie. Wyniki: Dane do analizy pozyskano od 280 respondentów metodą CAWI. Następnie zweryfikowano czynniki przy pomocy eksploracyjnej analizy czynnikowej. Do zbadania determinant (i siły ich wpływu) intencji akceptacji technologii oraz jej zastosowania w procesie zakupu zastosowano konfirmacyjną analizę czynnikową. Wnioski: Przeprowadzone badanie wskazało osobistą innowacyjność jako najsilniejszy predyktor zamiaru zakupu, któremu towarzyszy wpływ społeczny i oczekiwana wydajność. Zaobserwowano także, że postrzegane ryzyko i motywacja hedoniczna były nieistotne w tym badaniu. Odkryto, że nawyk jest wiarygodnym wskaźnikiem zarówno intencji akceptacji technologii omnichannelingu w procesie zakupu, jak i zachowań związanych z wykorzystywaniem tej technologii, podczas gdy warunki ułatwiające okazały się mieć związek tylko z wykorzystywaniem technologii omnichannelingu.

Opis:
In the context of the strong outbreak of the Covid-19 pandemic leading to increasing social distancing, it is difficult for businesses to access the labor market. Therefore, it is necessary to create a connection channel between the employer and the labor supplier. That helps to adapt to the context of the Covid-19 pandemic, while also taking advantage of the achievements from the Industrial Revolution 4.0. The development of a training model that connects human resource trainers with human resource users who are businesses is considered an important requirement in the context of the Covid-19 pandemic. The university-enterprise model demonstrates active cooperation and has a profound impact on teaching and scientific research activities in universities. Since then, constantly improving the quality of training to create labor products that meet the rigorous needs of enterprises. This study uses exploratory factor analysis methods to screen observations to analyze, evaluate and draw conclusions about the formation of a university-enterprise linkage model. Thereby helping to create a bridge in cooperation between universities and businesses. On that basis, propose solutions to promote cooperation between universities and businesses in the current Vietnamese conditions, contributing to creating high-quality labor for society, meeting the needs of digital businesses.

Opis:
This research evaluated rice growth and yield as well as Zn accumulation in both soil and grain under saline water irrigation conditions. The experiment consisted of a series of pots containing rice plants and paddy soil, with the application of irrigation treatments of five different salinity levels (1.5, 2, 3, 4, and 5‰ with a drip irrigation system). The results show that the salinity accumulation levels in soil can increase by up to 2.8‰ following the application of 5‰ salinity irrigation water during the development stages. Besides, this study also aimed to evaluate the influences of saline water irrigation on the observed rice yields, plant height, leaf length, and leaf width. In the results, irrigation with 3‰ saline water reduced potential rice yield by 58.6% and the length of rice leaves by one-third. Higher salinity of 4‰ in the irrigation water produced only 24% of average potential productivity, and 5‰ water salinity resulted in no yield. Furthermore, salt stress limited the mobile Zn content in paddy soil, reducing the Zn accumulation in grains by between 36.27% and 83.21%. Thus, the study shows that controlling salinity in irrigation water management is essential for controlling the yield and nutrient Zn content in rice grains.

Opis:
Trees play a critical role in creating green spaces in public areas such as streets, parks, schools, offices. Over time, the trees often get pests and diseases, and then rotten trees can break. To care for and conserve the trees, it is necessary to determine the condition inside the trunk, especially the possibility of having a hollow or not. Wood decay, modifications of moisture and ion content, density due to biotic and abiotic stress agents of water extremity, salinity, and infection strongly change (di-) electrical properties of wood. Hence, we propose to use electrical impedance tomography to detect the change in electrical properties inside the trees that can link to wood decay. In electrical impedance tomography, an array of electrodes is attached around the tree trunk, and small alternating currents are injected via these electrodes, so the resulting voltages are measured. Processing the data, we can construct the spatial distribution of impedance (or resistivity) of the object. In this work, we will present the preliminary results of our group research. We will show theoretical forward modeling results, followed by laboratory experiments and real data application. The results illustrate that electrical impedance tomography can be useful to define several decay scenarios inside the trees.

Opis:
Cadmium (Cd) is toxic for humans, but its effects on the yield and quality of rice under contaminated irrigation conditions remain uncertain. In this study, paddy soils in the Red River Delta (Vietnam) were selected for experiments with the purpose of understanding the effects of Cd contaminated irrigation water on growth, yields, and grain Cd accumulation. In addition, biochar was produced from rice husk (BRH) and rice straw for preventing Cd infiltration into rice was also studied in this experiment. A field experiment was established with applicated BRH and straw into polluted paddy soil, as a result the Cd content in grains reduced significantly. The Cd contaminated soil was added to the BRH and rice straw (RS) with six ratios, including: (1) RS 2.5%, (2) BRH 2.5%, (3) RS-BRH: 1.25–1.25%, (4) RS 5.0%, (5) BRH 5.0%, (6) RS-BRH: 2.5–2.5%, (w:w). Besides, three content levels 0.01–0.05–0.5 mg/L of Cd in irrigation water were applied throughout crop season. The results showed that the Cd accumulation in rice was in the following order: roots > stems > seeds. With 3 contaminated irrigation levels which were applied, the Cd concentrations of 0.05 mg/L and 0.5 mg/L affected plant height and yield. However, the Cd content in grains under contaminated soil condition can be controlled from 82.47–83.94% by applying a BRH ratio from 2.5–5% (w:w).

The investigations on the effects of biochar application in improving the physio-chemical properties of soil have been carried out in many studies; however, there are very few studies on the combined use of both biochar and clay-rich soil for poor nutrient soil reclamation. Therefore, this study demonstrates improved water retention and nutrient retention of sandy soil by using biochar and biochar combined with clay-rich soil. The experiments were conducted on a small scale (greenhouse) with nine different application rates of biochar and clay-rich soil were mixed and then cultivated peanut, along with the drip irrigation technique using field moisture limit (about 70-80%) was applied under the condition of ensuring a sufficient supply of NPK for plant’s growth. The results showed that at the rates from 10.0-15.0% (w/w) clay-rich soil mixed with from 0.5-1.5% (w/w) of biochar applied to the tested sandy soil resulted in the positive effects on soil water holding, bulk density, permeability, pH, CEC, OM, total N, total P and peanut yield. The physical and chemical characteristics of the tested sandy soil have been improved by time and the application rate of 10.0% clay-rich soil and 0.5% biochar had the highest efficiency of pod fresh weight and pod dry weight during three studied seasons.

Females in the industry nowadays have been offered many opportunities to develop their careers. However, the chances are not the same in different areas or sectors. This study investigated the perceptions and understanding of gender-related issues in the mining sector among potential young workers and industry experts in Vietnam. The study employs Oxfam's Gender Impact Assessment Guidelines for extractive industries and the Convention on the Elimination of All Forms of Discrimination Against Women - CEDAW's Women's Economic and Social Rights Framework to assess gender-related issues in the mining sector. A survey of 207 students in Hanoi was conducted, besides focus group discussions and in-depth interviews with gender and mining experts. Findings reveal significant differences in knowledge and awareness of gender issues between students, emphasizing the need to integrate gender knowledge into specialized fields such as mining. In addition, professionals working solely in the mining sector demonstrated a lack of sensitivity to gender issues. Consequently, the study recommends capacity building, seminars, and exchanges to help mining professionals incorporate a gender perspective into their activities. Current policies exhibit gender neutrality, indirectly excluding women's participation and compromising men's safety in the mining sector. The study proposes policy recommendations for enhancing the protection of workers in the mining industry and promoting gender equality. These include incorporating gender perspectives into relevant laws, raising awareness of gender issues among policymakers and professionals, and increasing the mining sector's presence in the media to encourage youth to pursue careers in this field.

Opis:
Recently, operational and supply chain management practices are considered the foremost solution for high operational performance and gain recent researchers' intentions. Thus, the present study aims to examine the role of operational management practices such as extensive training, teamwork, total quality management and just-in-time on the multinational organization's operational performance in Vietnam. The goals also include the examination of the mediating impact of green practices of supply chain among the nexus of operational management practices and operational performance of the multinational organization in Vietnam. The operational and supply chain managers of the multinational organization in Vietnam are the respondents of the study that have been selected by using purposive sampling. The questionnaires have been sued for the data collection, and smart-PLS has been executed for analysis. The results revealed that all the operational management practices have a positive and significant association with multinational organizations’ operational performance in Vietnam. The findings also exposed that the supply chain's green practices are positively mediating among the nexus of operational management practices and operational performance of the multinational organization in Vietnam. These outcomes are suitable for the regulators to develop the policies related to the operational and supply chain practices that could increase organizational performance.
Ostatnio praktyki zarządzania operacyjnego i zarządzania łańcuchem dostaw są uważane za najważniejsze rozwiązanie zapewniające wysoką wydajność operacyjną i zyskują najnowsze zamierzenia badaczy. W związku z tym niniejsze badanie ma na celu zbadanie roli praktyk zarządzania operacyjnego, takich jak szeroko zakrojone szkolenia, praca zespołowa, kompleksowe zarządzanie jakością i „just in time” na wyniki operacyjne organizacji wielonarodowej w Wietnamie. Cele obejmują również zbadanie pośredniczącego wpływu ekologicznych praktyk w łańcuchu dostaw w powiązaniu praktyk zarządzania operacyjnego i wyników operacyjnych wielonarodowej organizacji w Wietnamie. Kierownicy operacyjni i łańcucha dostaw międzynarodowej organizacji w Wietnamie są respondentami badania, którzy zostali wybrani na podstawie celowego pobierania próbek. Kwestionariusze zostały pozwane w celu zebrania danych, a smart-PLS został wykonany do analizy. Wyniki ujawniły, że wszystkie praktyki zarządzania operacyjnego mają pozytywny i znaczący związek z wynikami operacyjnymi organizacji międzynarodowych w Wietnamie. Ustalenia ujawniły również, że zielone praktyki łańcucha dostaw pozytywnie pośredniczą w powiązaniu praktyk zarządzania operacyjnego i wyników operacyjnych wielonarodowej organizacji w Wietnamie. Wyniki te są odpowiednie dla organów regulacyjnych do opracowania polityk związanych z praktykami operacyjnymi i praktykami łańcucha dostaw, które mogą zwiększyć wydajność organizacji.

Opis:
PLLA-g-LMWNR (LMWNR – low molecular weight natural rubber) was used as a compatibilizer (1–3 wt %) of poly(L-lactic acid)/deproteinized natural rubber (PLLA/DPNR) blend (95/5 w/w). The LMWNR was prepared using TiO2/ZnO (9 : 1 w/w) and H2O2 as co-catalyst. The obtained LMWNR was grafted with 0–12 wt % maleic anhydride (LMWNR-g-MA) and then with PLLA (PLLA-g-LMWNR). A significant improvement in the mechanical properties of the PLLA/DPNR blend was found in the blend that contained 3 wt % PLLA-g-LMWNR. Scanning electron microscopy showed a decrease in the pore diameter from 5.44 to 1.56 μm. The thermal analysis of PLLA/DPNR blends showed that the Tg value of PLLA phase shifted from 63.1 to 61.4°C. These results confirmed that PLLA-g-LMWNR can enhance the compatibility of the PLLA/DPNR blend.
PLLA-g-LMWNR (LMWNR – kauczuk naturalny o małym ciężarze cząsteczkowym) stosowano jako kompatybilizator (1–3% mas.) mieszaniny PLLA/DPNR [poli(L-kwas mlekowy)/zdeprotonowany kauczuk naturalny] (95/5 w/w). LMWNR otrzymano z DPNR przy użyciu TiO2/ZnO (9 : 1 w/w) i H2O2 jako kokatalizatora, a następnie szczepiono bezwodnikiem maleinowym w ilości 0–12% mas. (LMWNR-g-MA). PLLA-g-LMWNR uzyskano w wyniku szczepienia PLLA z LMWNR-g-MA. Stwierdzono poprawę właściwości mechanicznych mieszaniny PLLA/DPNR zawierającej 3% mas. PLLA-g-LMWNR. Metodą SEM wykazano zmniejszenie średnicy porów z 5,44 do 1,56 μm. Wartość temperatury zeszklenia Tg fazy PLLA mieszaniny PLLA/DPNR, wyznaczona metodą analizy termicznej, zmniejszyła się z 63,1 do 61,4°C. Uzyskane wyniki potwierdziły, że dodatek PLLA-g-LMWNR zwiększa kompatybilność mieszaniny PLLA/DPNR.
