The primary purpose of this paper is to probe into the natural character of the experience in IT R＆D department, and put forward the strategy of how to manage it. The research on the strategies is applied in a mobile phone game software company to further validate its efficiency. The results indicate using the strategies of ＂a learning history＂ and ＂dynamic knowledge map＂ can improve the performance level and more attentions should focus on the relationship between people and how to communicate.展开更多

A rapid increase of cashew plantations has significantly changed the natural landscape in the North part of C<span style="white-space:nowrap;">?</span>te d’Ivoire. This study was conducted in the department of Niakaramadougou to assess the natural landscape change due to cashew plantations from 1989 to 2017. Satellite image data were used in order to evaluate land use land cover (LULC) change. The maximum likelihood pixel-based on classification method was used to analyze the spatio-temporal LULC dynamics for the years 1989, 2000, and 2017. The results showed an increase in cashew culture by 20.68% between 1989 and 2017 to the detriment of the savannah. Thus, the land devoted to old fallows or to other crops such as rice, maize, yams, peanuts, sorghum) is decreasing and the natural vegetation is becoming more and more fragmented, with consequences that are not yet known. This surely contributes to the reduction of plant diversity.展开更多

In order to highlight the geology of the area studied, 14 samples were taken for studies using petrographic, geochemical and metallogenic methods. The study of macroscopic and microscopic petrography made it possible to highlight two major lithological units: 1) a volcano-plutonic unit, formed of gabbros, basalt, volcaniclastics and rhyodacite;2) a sedimentary unit (microconglomerate). From a geochemical point of view, the results obtained indicate that the plutonites are gabbro and gabbro diorite while the volcanics have compositions of basaltic andesites, rhyolite and dacites. The sediments have a litharenitic to sublitharenitic character. The metallogenic study made it possible to highlight hydrothermal alterations and metalliferous paragenesis on the formations studied. Hydrothermal alteration is characterized by the presence of carbonation, silicification, sericitization, sulfidation and to a lesser degree chloritization. Metalliferous paragenesis consists of pyrite, chalcopyrite, hematite and magnetite.展开更多

These countries, located in regions prone to unpredictable temperature and precipitation changes, are facing significant challenges, particularly in climate-sensitive sectors such as mining and agriculture. LDCs need more resilience to adverse climate shocks but have limited capacity for adaptation compared to other developed and developing nations. This paper examines Liberia’s susceptibility to climate change as a least developed country, focusing on its exposure, sensitivity, and adaptive capacity. It provides an overview of LDCs and outlines the global distribution of carbon dioxide emissions. The paper also evaluates specific challenges that amplify Liberia’s vulnerability and constrain sustainable adaptation, providing insight into climate change’s existing and potential effects. The paper emphasizes the urgency of addressing climate impacts on Liberia and calls for concerted local and international efforts for effective and sustainable mitigation efforts. It provides recommendations for policy decisions and calls for further research on climate change mitigation and adaptation.展开更多
