This study was focused on analyzing the farmers’ perception of climate change by examining three vital issues: (1) description of the socioeconomic characteristics of farmers;(2) reporting on the perception of farmers experiences with climatic change;and (3) identification of the socio-economic factors associated with farmers’ perception of climate change. The study area encompasses three villages within the coastal region (Sathkhira district) of Bangladesh, a geographic region where climate change literature has highlighted as prone to accelerated degradation. A logit model, along with weighted indexes for ranking and descriptive statistics, was used to analyze the result of 100 farmers surveyed by questionnaire. We found that the majority of the farmers (88%) perceived changes in climatic conditions. Almost all farmers indicated increases in temperature, droughts, floods, cyclones, salinity level and decreasing rainfall over the last 20 years. The logit model explained that out of the nine factors surveyed;education, family size, farm size, family income, farming experiences and training received were significantly related and influential factors to perception of climate change. Therefore, government and non-governmental organizations are recommended to push forward with interventions, especially focusing on identified factors, in order to strengthen the farmers’ capacity to battle against climate change effects.展开更多

A decrease of rainfall and rise in temperature has been increasing the exposure of the country to frequent drought. The study was conducted in central Tigray, Adiha tabia, to examine the perception of farmers on trends of climate changes and existing coping strategies. Farmers’ knowledge of various adaptation strategies, drought early warning system and weather forecasting were assessed using focus group discussion (FGD), which consisted of 144 systematically sampled respondents. Temperature is rising while precipitation is declining from time to time. Untimely rain and frequent drought are challenging crop production in the area. Drought is perceived, both by male and female respondents, as the primary climate related hazard which is occurring frequently and affecting their livelihood. Individual’s vulnerability to this hazard varies based on their hazard coping capacity. Lack of modern early warning systems, inflexible cropping calendar and narrow choice of crop varieties should aggravates the vulnerability. Hence, improving forecasting and dissemination of climate information, developing drought resistant varieties and promoting farm-level adaptation measures like use of irrigation technologies and adjusting planting dates should be prioritized to improve community resilience to climate change.展开更多

This study investigated local climate changes, farmers’ perception of the changes and factors affecting perception to climate change in the Kyoga plains of Uganda. Monthly maximum temperature, minimum temperature and total rainfall from four meteorological stations within the study area for period 1984-2014 were obtained to analyse seasonal, annual and decadal trends in rainfall and temperature while a survey based on 384 randomly selected farmers was carried out to investigate the perception of variation in climate change trends among small holder farmers of different socioeconomic characteristics across the Kyoga plains. Multi stage random sampling was applied in the selection of the population sample. Non parametric analysis (Mann Kendall test) was used for analyzing trends and testing significance. In the survey, farmers were asked their observations about the local climate using structured questionnaires and these were analysed using descriptive statics. Logistics regression was then used to identify the factors that determined the perceptions of farmers on climate change. Overall, trends in monthly temperature are increasing over the years but not significantly while rainfall is decreasing but equally not significantly. Seasonal and decadal temperature had significant positive trends at different stations and sub zones over the years. 67% of the farmers realised a decrease in rainfall while 56.8% perceived an increase in temperature across the agroecological zone. 56.3% perceived declining rainfall and 52% realized increasing temperature in the southern sub zone while 42% realised a decrease in rainfall and 40.6%, an increase in temperature in the northern sub zone. Belonging to a group and age has significant positive effect on farmers’ perception of climate while farming experience and access to extension workers had a significant negative effect. The results suggest the need for strengthening networking among farmers for peer learning and support and location specific intervention measures to improve perception and adaptation to climate for each of the sub zones.展开更多

The zone was classified as lowland (<1500), midland (1500 - 2500), and highland (>2500 m.a.s.l) based on altitudinal variation from which a total of three districts one per cluster were selected through random sampling. 150 households were selected through systematic random sampling targeting Fogera cattle owners for primary data collection. Over 36 years (from 1983-2019) of meteorological data were taken from the National Meteorological Agency. Meteorological data result confirmed that climate was changing across all the agro-ecological zones. Both the mean annual maximum and minimum temperature was considerably increasing for all agro-ecological zones whereas the mean annual rainfall was decreasing which is consistent with the farmers’ perception. Meteorological data result also showed that the short rainy and dry season rainfall indicated high interannual variability at all agro-ecological zones. Survey result revealed that 97.13% of the farmers recognized climate change and variability impact in all agro-ecological zones. About 80.91% of Fogera cattle farmers reported the incidence of negative impacts of climate change and variability on cattle. Chi-square test values of survey results show that in all agro-ecological zones frequency of drought, duration of dry spell, wind, and floods were ever-increasing (p < 0.001). Moreover, about 84.48%, 65.3%, and 60.47% of farmers owning Fogera cattle in the lowland, midland, and highland, respectively perceived the prevalence of increasing (p < 0.001) cattle mortality. In response to climate change and variability, farmers were reducing number of livestock, diversification of livestock species, and replacing Fogera cattle with small ruminants as adaptation strategies. Thus, regular prediction of climate change and variability and designing pertinent response strategies is essential to reduce the adverse impacts of climate change for enhancing resilience capacity of the Fogera cattle farmers in the study areas.展开更多

In the exploratory phase of the project, we studied stakeholders’ opinions on the positive and negative impacts of introducing livestock activities within a forest environment, as well as breeders’ constraints or motivations for setting up livestock units within agroforestry systems in the private forests of Guadeloupe. To establish a diagnosis of the current situation, 51 stakeholders (St) and 49 farmers (Fr) were interviewed on their perceptions, opinions, motivations and preferences. Forty-one percent of the St has had a generally positive appreciation of livestock activities, while on the opposite 31% have had a resolutely negative posture depending on their area of expertise. Their views on the possible positive effects or negative interactions between livestock and agroforestry activities were analysed in order to suggest possible approaches for the authorities or associations. Unanimously, the farmers replied that their motivations followed economic strategies: for self-consumption or sale. But their decision-making processes were also non-economic. Many of them (36% Fr) gave importance to their activity in the construction of their identity, whether it was through a desire to perpetuate traditions or to maintain family activities. The main constraints identified were natural constraints (61% Fr), including topography, climate and predators. While 28% of Fr notified their motivations for environmental protection. Another constraint was of a technical nature (44% Fr) since farmers asked for more technical references or support services. Further researches are required to study the interactions between animals and the undergrowth by describing their respective ecosystem services in order to enhance their positive interactions.展开更多

The specific objectives were to describe the socio-economic characteristics of cassava farmers in the area and to examine the farmers’ climate change risk perception through examining their perception of the various sources of climate change risk. Multi-stage sampling technique was used to select one hundred and sixty (160) respondents who were selected from 40 communities and 8 Local Government Areas from across the four Agricultural Zones of the state. Data were obtained through the administration of structured questionnaire to the respondents. Data collected were analyzed using descriptive statistics, weighted mean obtained from Likert scale, and Tobit regression model. The results of the socioeconomic characteristics of farmers showed that majority of the farmers had formal education and only 15.19% had no formal education, 56.74% of the farmers had 11 years of farming experience. The farmers’ risk perception showed that the most important risk factors perceived by cassava farmers in their farm were flooding/erosion, increased frequency and intensity of rainfall and incidence of pest and diseases. The factors that influenced the farmers’ level of risk perception included age, level of education, access to extension agents and access to climate change information. Based on the findings of cassava farmers’ level of risk perception, it was inferred that the farmers have reasonable perception of climate change risk. It was therefore recommended from the findings of this research that there is need for effective and functional extension services and provision of enabling environment and policies that will help boost the socio-economic welfare of farmers as this will significantly help in the management of climate change risk in the study area.展开更多

Previous surveys confirmed that coffee grown in central Uganda was largely depending on bee pollination to set fruit set. Despite its high contribution to the economics of agricultural sector in Uganda and despite its great dependency to bees for fruit set, it is not clear if small-scale farmers are aware of the importance of managing farm-landscapes for pollination services conservation to increase coffee yield. The aim of this study was to assess farmers’ perceptions and knowledge of the importance of pollinators and pollination services conservation for coffee production enhancement. The main hypothesis was that small-scale coffee growers were not aware of the relevance of pollination services for coffee production. Farmers’ surveys were conducted in coffee-banana farming systems in central Uganda. It was found in this study that more than 90% of interviewed farmers were not aware of the role played by bees in coffee yield increase. Farmers were not willing to manage their lands to protect pollination services, particularly because they considered pollination service as an unsolicited “free service”, or as a “public good”. Farmers were not aware of the role of semi- natural habitats serving as reservoir (hiding points) for pollinators in the surrounding of coffee fields. However, they were aware of some ecosystem services delivered in the coffee- banana farming system such as planting shading trees. Only 3.3% of respondents believed that placing beehives in coffee farms could increase the yield. The study recommended the increase of the awareness of small-scale coffee growers on the importance of pollinators to increase coffee production. It is recommended that future management of pollination services are built on improving farmers’ indigenous knowledge and on adequate understanding of the ecology of the local pollinator species. There is a need to broadly scale-up best field, habitat and landscape management strategies and practices that are friendly to coffee pollinators in rural landscapes of展开更多

However, because of environmental change, this knowledge is mostly disregarded. The use of farmers' knowledge is important for the identification of relevant information for the choice of agricultural land units. The objective of this study was to compare farmers' perceptions of soil fertility with a conventional scientific approach in two locations of the forest margin zone of Center Cameroon. Through interviews and soil analysis, this study spelled and weighed the relationships between farmers' perceptions and soil fertility status. One hundred and twenty households' heads were interviewed and 30 soil samples collected. Farmers' perceptions were used to assess the topsoil fertility status across the studied areas, while a conventional scientific approach was used to quantify soil fertility status by the means of a soil fertility index (SFI). Results showed that farmers, for soil differentiation, used color, texture, depth, drainage and vegetation. Soil' names delivered key messages for their location. Although the low overall SFI approximated by the conventional approach, farmers' perceptions could differentiate fertility levels between soils. This knowledge is relevant for the design of technical innovations in perceived fertility niches.展开更多

However, mountain regions worldwide are impacted by climate change and at the same time represent distinctive area for the assessment of climate related impacts. Climate change impacts in Himalayan region have its implications on food production, natural ecosystems,retreat of glacier, water supply, human and animal health and overall human well being. The livelihood and food security of the people inhabited in region largely depend on climate sensitive sectors i.e.agriculture, livestock, forestry and their interlinkages with each other, and has the potential to break down food and nutritional security as well as livelihood support systems. People's perception and understanding of climate can be an important asset when it comes to adaptation to climate change impact;however it is not taken into consideration for the development of policy design and implementation of modern mitigation and adaptation strategies by governments and other civil society organizations.The knowledge of local people and farming communities for rural landscape management and sustainable use of bioresources is gaining credence as a key strategy to cope up with the climate change.Therefore, the present study analyzes the indigenous knowledge of local people and their perceptions on climate change, and also documented adaptation approaches at local level in mountain ecosystem of western Himalaya. The study could be useful to policy makers to design appropriate adaptation strategies to cope up with the impacts of climate change.展开更多

While scientific knowledge on climate threats and changing climate patterns are essential, it is also important to consider the impacts in relation to how the threats are perceived and handled by local people. This paper intends to assess the trend and people’s perception on temperature and precipitation. Three focus groups’ discussion and a total number of 240 households were interviewed during field visit. The collected information was scaled from the least preferred-1 to the most preferred-5 based on their preferences. The trend of mean of annual average, maximum and minimum temperature indicates that the temperature has increased significantly and precipitation intensity and magnitude are also in increasing trend in the monsoon and postmonsoon seasons which may raise the extreme flood events. These facts were verified with the people’s perception. This finding could be useful for formulation of effective flood management policy and plan in this river basin as well as very applicable for other similar areas.展开更多

Nursing students enrolled in an accelerated master’s program in nursing (N = 45) were surveyed to assess their knowledge of the DNP degree while also identifying the perceived effect a DNP might have on their careers, on nursing as a discipline, and on public perceptions of nursing practice. In this study, 51% of participants supported the transition to the DNP as the standard degree for practice nursing while 29% were opposed. The majority of participants (71%) planned to pursue an advanced practice nursing degree/certification with 81% of this group signifying that they would do so even if a DNP is required. The majority of participants agreed that the DNP will improve public perception of advanced practice nursing, but 71% thought the title of “doctor” would confuse patients. While current nursing students are generally informed of the upcoming DNP transition, there is disagreement regarding its implications for their careers and for the extent of public understanding.展开更多

In this essence, fighting and eliminating any means of corruption in the public and private companies have been one of the key challenges in the long run. The globalization of businesses has somehow led to an increase in the number of unethical conduct and hazardous corruption. In the urge to enliven ethics and integrity in a company and among employees, the whole business processes and stakeholders should position code of ethics and integrity at its highest standard. However, can ethics and integrity really increase the company's reputation, strengthening its business operations and sustainability, and deliver trust amongst employees and employers? The objective of this study is to analyze the perceptions of employees on issues pertaining ethics and integrity. The study has been conducted in one of the giant telecommunication companies in Malaysia where a sample of 7,056 employees were the participants involved in the survey. The study has used questionnaires to collect data. The data have then been analysed using the SPSS data analysis software. The findings explained that employees view the company as an ethical place to work where the finance department is deemed to have the highest level of integrity. While in matters of corruption risk areas, there are still practices of bribery. It is also founded that a majority of respondents about 93% agree that the company's initiatives are effective in building business integrity and that the level of business ethics and integrity has improved over the last two years. Running a business with ethics and integrity while selecting the fight business partners will create a corporation of ethics, integrity, and anti-corruption.展开更多

Moreover, about 84.48%, 65.3%, and 60.47% of farmers owning Fogera cattle in the lowland, midland, and highland, respectively perceived the prevalence of increasing (p < 0.001) cattle mortality. In response to climate change and variability, farmers were reducing number of livestock, diversification of livestock species, and replacing Fogera cattle with small ruminants as adaptation strategies. Thus, regular prediction of climate change and variability and designing pertinent response strategies is essential to reduce the adverse impacts of climate change for enhancing resilience capacity of the Fogera cattle farmers in the study areas.
文摘The Valab project (Integrated Ecosystemic value-enhancement of the Guadeloupean Forest Agrobiodiversity) is a participatory action research that aims to explore the feasibility of diversification activities within the forest understorey. In the exploratory phase of the project, we studied stakeholders’ opinions on the positive and negative impacts of introducing livestock activities within a forest environment, as well as breeders’ constraints or motivations for setting up livestock units within agroforestry systems in the private forests of Guadeloupe. To establish a diagnosis of the current situation, 51 stakeholders (St) and 49 farmers (Fr) were interviewed on their perceptions, opinions, motivations and preferences. Forty-one percent of the St has had a generally positive appreciation of livestock activities, while on the opposite 31% have had a resolutely negative posture depending on their area of expertise. Their views on the possible positive effects or negative interactions between livestock and agroforestry activities were analysed in order to suggest possible approaches for the authorities or associations. Unanimously, the farmers replied that their motivations followed economic strategies: for self-consumption or sale. But their decision-making processes were also non-economic. Many of them (36% Fr) gave importance to their activity in the construction of their identity, whether it was through a desire to perpetuate traditions or to maintain family activities. The main constraints identified were natural constraints (61% Fr), including topography, climate and predators. While 28% of Fr notified their motivations for environmental protection. Another constraint was of a technical nature (44% Fr) since farmers asked for more technical references or support services. Further researches are required to study the interactions between animals and the undergrowth by describing their respective ecosystem services in order to enhance their positive interactions.
文摘This study analyzed the determinants of climate change risk perception among cassava farmers in Anambra state, Nigeria. The specific objectives were to describe the socio-economic characteristics of cassava farmers in the area and to examine the farmers’ climate change risk perception through examining their perception of the various sources of climate change risk. Multi-stage sampling technique was used to select one hundred and sixty (160) respondents who were selected from 40 communities and 8 Local Government Areas from across the four Agricultural Zones of the state. Data were obtained through the administration of structured questionnaire to the respondents. Data collected were analyzed using descriptive statistics, weighted mean obtained from Likert scale, and Tobit regression model. The results of the socioeconomic characteristics of farmers showed that majority of the farmers had formal education and only 15.19% had no formal education, 56.74% of the farmers had 11 years of farming experience. The farmers’ risk perception showed that the most important risk factors perceived by cassava farmers in their farm were flooding/erosion, increased frequency and intensity of rainfall and incidence of pest and diseases. The factors that influenced the farmers’ level of risk perception included age, level of education, access to extension agents and access to climate change information. Based on the findings of cassava farmers’ level of risk perception, it was inferred that the farmers have reasonable perception of climate change risk. It was therefore recommended from the findings of this research that there is need for effective and functional extension services and provision of enabling environment and policies that will help boost the socio-economic welfare of farmers as this will significantly help in the management of climate change risk in the study area.
文摘Coffee (Coffea canephora) is the principal cash crop and the country’s largest agricultural foreign revenue earner in Uganda. Previous surveys confirmed that coffee grown in central Uganda was largely depending on bee pollination to set fruit set. Despite its high contribution to the economics of agricultural sector in Uganda and despite its great dependency to bees for fruit set, it is not clear if small-scale farmers are aware of the importance of managing farm-landscapes for pollination services conservation to increase coffee yield. The aim of this study was to assess farmers’ perceptions and knowledge of the importance of pollinators and pollination services conservation for coffee production enhancement. The main hypothesis was that small-scale coffee growers were not aware of the relevance of pollination services for coffee production. Farmers’ surveys were conducted in coffee-banana farming systems in central Uganda. It was found in this study that more than 90% of interviewed farmers were not aware of the role played by bees in coffee yield increase. Farmers were not willing to manage their lands to protect pollination services, particularly because they considered pollination service as an unsolicited “free service”, or as a “public good”. Farmers were not aware of the role of semi- natural habitats serving as reservoir (hiding points) for pollinators in the surrounding of coffee fields. However, they were aware of some ecosystem services delivered in the coffee- banana farming system such as planting shading trees. Only 3.3% of respondents believed that placing beehives in coffee farms could increase the yield. The study recommended the increase of the awareness of small-scale coffee growers on the importance of pollinators to increase coffee production. It is recommended that future management of pollination services are built on improving farmers’ indigenous knowledge and on adequate understanding of the ecology of the local pollinator species. There is a need to broadly scale-up best field, habitat and landscape management strategies and practices that are friendly to coffee pollinators in rural landscapes of
文摘In Cameroon, most farmers rely on their perceptions for fertility evaluation and choice of agricultural land units. However, because of environmental change, this knowledge is mostly disregarded. The use of farmers' knowledge is important for the identification of relevant information for the choice of agricultural land units. The objective of this study was to compare farmers' perceptions of soil fertility with a conventional scientific approach in two locations of the forest margin zone of Center Cameroon. Through interviews and soil analysis, this study spelled and weighed the relationships between farmers' perceptions and soil fertility status. One hundred and twenty households' heads were interviewed and 30 soil samples collected. Farmers' perceptions were used to assess the topsoil fertility status across the studied areas, while a conventional scientific approach was used to quantify soil fertility status by the means of a soil fertility index (SFI). Results showed that farmers, for soil differentiation, used color, texture, depth, drainage and vegetation. Soil' names delivered key messages for their location. Although the low overall SFI approximated by the conventional approach, farmers' perceptions could differentiate fertility levels between soils. This knowledge is relevant for the design of technical innovations in perceived fertility niches.

文摘The Himalaya represents a vast mountain system and globally valued for its significant role in regulation of global as well as regional climate that has direct impact on biodiversity and ecosystem services crucial for sustenance of millions of people in Himalaya and adjoining areas. However, mountain regions worldwide are impacted by climate change and at the same time represent distinctive area for the assessment of climate related impacts. Climate change impacts in Himalayan region have its implications on food production, natural ecosystems,retreat of glacier, water supply, human and animal health and overall human well being. The livelihood and food security of the people inhabited in region largely depend on climate sensitive sectors i.e.agriculture, livestock, forestry and their interlinkages with each other, and has the potential to break down food and nutritional security as well as livelihood support systems. People's perception and understanding of climate can be an important asset when it comes to adaptation to climate change impact;however it is not taken into consideration for the development of policy design and implementation of modern mitigation and adaptation strategies by governments and other civil society organizations.The knowledge of local people and farming communities for rural landscape management and sustainable use of bioresources is gaining credence as a key strategy to cope up with the climate change.Therefore, the present study analyzes the indigenous knowledge of local people and their perceptions on climate change, and also documented adaptation approaches at local level in mountain ecosystem of western Himalaya. The study could be useful to policy makers to design appropriate adaptation strategies to cope up with the impacts of climate change.
文摘In the context of climate change, the frequency and intensity of extreme events such as floods and droughts will increase which could put tremendous challenges in water resources management in the coming days. While scientific knowledge on climate threats and changing climate patterns are essential, it is also important to consider the impacts in relation to how the threats are perceived and handled by local people. This paper intends to assess the trend and people’s perception on temperature and precipitation. Three focus groups’ discussion and a total number of 240 households were interviewed during field visit. The collected information was scaled from the least preferred-1 to the most preferred-5 based on their preferences. The trend of mean of annual average, maximum and minimum temperature indicates that the temperature has increased significantly and precipitation intensity and magnitude are also in increasing trend in the monsoon and postmonsoon seasons which may raise the extreme flood events. These facts were verified with the people’s perception. This finding could be useful for formulation of effective flood management policy and plan in this river basin as well as very applicable for other similar areas.
文摘Bloom’s taxonomy is widely used in educational research to categorize the cognitive skills required to answer exam questions.For this study,we analyzed how students categorize exam questions(high-level question or low-level question,)gathered data as to their rationale for categorization,and compared their categorizations to those of experts.We found that students consistently rank high-level questions incorrectly.We analyzed student reasons for their categorizations,and found that for many of the incorrectly categorized questions the students referred to reasons related to Cognitive Load Theory.This shows that cognitive load prevents students from accurately assessing the cognitive level of an exam question.Thus,extra cognitive load in exam questions may prevent those questions from accurately measuring the skills and knowledge of the student.This points to the need for instructors to eliminate cognitive load from their exams.

文摘The local visual motion detection mechanism used in the visual systems of primatescan only sense the motion component oriented perpendicularly to the contrast gradient of thebrightness pattern.But the visual system of higher animals can adaptively determine the actualdirection of motion through a learning process.In this paper a multilayered feedforward neuralnetwork model for perception of visual motion is presented.This model employs W.Reichardt’selementary motion detectors array and T.Kohonen’s self-organizing feature map.We explored theself-organizing principles for perception of visual motion.The computer simulations show thatthis neural network is able to recognize the true direction of motion through an unsupervisedlearning process.In addition,the neurons with the same or similar motion direction selectivitytend to appear in“functional columns”which seem to be qualitatively similar to the corticalmotion columns observed by electrophysiological and cytohistochemical studies in certain higherareas such as MT.It proves that motion-detection by spatio-temporal coherences,mapping,co-operation,competition,and Hebb rule may be the basic principles for the self-organization ofvisual motion perception networks.
文摘While the nursing community generally agrees that the Doctorate of Nursing Practice (DNP) degree will strengthen nursing as an academic discipline, there is little known about students’ perceptions of the advanced degree. Nursing students enrolled in an accelerated master’s program in nursing (N = 45) were surveyed to assess their knowledge of the DNP degree while also identifying the perceived effect a DNP might have on their careers, on nursing as a discipline, and on public perceptions of nursing practice. In this study, 51% of participants supported the transition to the DNP as the standard degree for practice nursing while 29% were opposed. The majority of participants (71%) planned to pursue an advanced practice nursing degree/certification with 81% of this group signifying that they would do so even if a DNP is required. The majority of participants agreed that the DNP will improve public perception of advanced practice nursing, but 71% thought the title of “doctor” would confuse patients. While current nursing students are generally informed of the upcoming DNP transition, there is disagreement regarding its implications for their careers and for the extent of public understanding.

文摘Thurstone’s Comparative Judgment Model was applied to measure characteristics of tourists’after-trip perception of landscape preference in the Confucius Temple,a famous historical block in Nanjing City.The results show that(a)as time goes by,the tourists’time perception differentiation has continuously sublimated from the general experience into the peak experience,and gradually evolved into the core experience element in the overall perception.In terms of content,perceptional contents of tourists decrease in sequence of the Confucian culture,the commercial culture and the culture of refined scholars.As a whole,tourists’after-trip perception differentiation has 3 sections:halo zone,sub-halo zone,and gray zone.(b)Because of tourism development,the Confucian culture is influenced by other cultures,and the commercial culture shows the trend of"over-generalization",and the culture of refined scholars has weakening carriers and modes of inheritance.Inheritance of its unique cultural connotations deserves increasing attention.
文摘Malaysia has long been involved in the initiative of becoming a high income country by the year 2020. In this essence, fighting and eliminating any means of corruption in the public and private companies have been one of the key challenges in the long run. The globalization of businesses has somehow led to an increase in the number of unethical conduct and hazardous corruption. In the urge to enliven ethics and integrity in a company and among employees, the whole business processes and stakeholders should position code of ethics and integrity at its highest standard. However, can ethics and integrity really increase the company's reputation, strengthening its business operations and sustainability, and deliver trust amongst employees and employers? The objective of this study is to analyze the perceptions of employees on issues pertaining ethics and integrity. The study has been conducted in one of the giant telecommunication companies in Malaysia where a sample of 7,056 employees were the participants involved in the survey. The study has used questionnaires to collect data. The data have then been analysed using the SPSS data analysis software. The findings explained that employees view the company as an ethical place to work where the finance department is deemed to have the highest level of integrity. While in matters of corruption risk areas, there are still practices of bribery. It is also founded that a majority of respondents about 93% agree that the company's initiatives are effective in building business integrity and that the level of business ethics and integrity has improved over the last two years. Running a business with ethics and integrity while selecting the fight business partners will create a corporation of ethics, integrity, and anti-corruption.
