ORGANIZATIONAL CULTURE AND ETHICAL BEHAVIOUR: A STRATEGIC STANDPOINT
What constitutes ethical behaviour lies in a “grey zone†where clearcut right versus wrong and good versus bad dichotomies may not always exist. This paper is an empirical study on organizational culture and ethical behaviour from a strategic standpoint. Its objectives were to determine if there is a significant relationship between organizational culture and ethical behaviour and if there is a significant relationship between organizational culture and employees’ values. The participants of the study were employees of selected public and private organizations in Lagos, Nigeria. The selection was through simple random sampling technique. The sample size was 92 respondents. Two (2) hypotheses were formulated and tested using regression analysis. Hypothesis one revealed that there is significant relationship between organizational culture and ethical behavior; the coefficient of determination (R2) is 0.370. It shows that 37% of the variation or change in ethical behaviour is caused by variation in organizational culture. Hypothesis two also shows that the coefficient of determination (R2) is 0.423. It means that 42.3% of the variation or change in employees’ values is caused by variation in organizational culture, which connotes that organizational culture has significant relationship with employees’ values. The study recommends that management should constantly review its organizational culture to be sure that it remains strong on the vision of the founders of the organisation, because organizational culture can be eroded as more people come into the organization with their various individual behaviours and values. Â
Chapter 31 - Application of nanochitosan in tagging and nano-barcoding of aquatic and animal meats
Nanochitosans obtained from crustacean shells are biodegradable and biocompatible offering valuable functional, nutritional, and binding properties. Their low toxicity favors diverse industrial applications in various research models and can enable their use in the tagging of commercially sold aquatic and animal meat, easily contaminated by microbial sources during packaging, storage, and transportation. In this capacity, nanochitosans have been applied in fingerprinting for tracking and identifying the manufacturing and expiry dates of commercially sold meats and fish, as well as delivery of antioxidants and antimicrobials in these food products without affecting product consistency, composition, and organoleptic property. This chapter reviews current research on chitosan-based nanoparticles as barcodes and biosensors in tagging and monitoring aquatic and animal meats; and highlights methods of fish tagging and coding, and the benefits as well as the properties of materials used as biosensors in nano-barcoding of fish and meat
Next Generation Nanochitosan Applications in Animal Husbandry, Aquaculture and Food Conservation
Studies have identified the properties of enzymes, functionalized
molecules, and compounds in food industry applications as edible
coatings and encapsulations, that assure prolonged food quality and
standards. These molecules present benefits of longer shelf-life by
delayed deterioration and inhibition of the proliferation of spoilage and
mycotoxigenic microorganisms. However, challenges of reduced
nutrient levels, miniaturized size, and low chemical stability remain
concerning. Chitosan polymers naturally formed from the
deacetylation of shellfish shells and exoskeletons of aquatic
arthropods and crustaceans offer improved benefits when
functionalized into nanoparticles as nanochitosans. These
polysaccharides produced by the alkalescent deacetylation of chitin,
comprise a series of 2-deoxy-2 (acetylamino) glucose linked by ß-(1-
4) glycosidic linkages. This chapter considers the health impacts and
microbiological health hazards associated with animal feeds quality
and the enzyme immobilization potentials of nanochitosans in animalbased
food and feed packages. Thereafter, nanochitosan properties
and benefits are compared against traditional preservatives from
microbes and plants; with highlights on current challenges in the
application of nanochitosan for enzyme immobilization
Chapter 21 - Utilization of nanochitosan in the sterilization of ponds and water treatment for aquaculture
Water pollution constitutes the leading cause of infant mortality,
neonatal deformities, and shrinkage of man’s average life expectancy.
Pollutants come from point and nonpoint sources; and water pollution
arises from the discharge of wastewater containing undesirable
impurities used for domestic, agricultural, and industrial purposes.
More so, high nutrient and wastewater runoffs from fish production
systems contribute to the fouling and eutrophication of recipient water
bodies. Hence, aquaculture which is inextricably linked to the natural
environment is challenged by the dearth of appropriate water quantity
and quality, militating against fish, and fishery production.
Nanochitosans as polysaccharides produced by the alkalescent
deacetylation of chitin, comprise a series of 2-deoxy-2 (acetylamino)
glucose linked by ß-(1-4) glycosidic linkages. They are naturally
formed from the deacetylation of shellfish shells and exoskeletons of
aquatic arthropods and crustaceans. The unique attributes of chitin
confer a wide range of biotechnological applications on the polymer,
observed in flocculation as a wastewater treatment and purification
route initiated by chitosan. This chapter highlights nanochitosan properties of aquaculture relevance; and elucidates the purification
potentials of nanochitosan, compared to inorganic coagulants and
organic polymeric flocculants. Effects of chitosan on contaminants and
microorganisms, as well as applications in fish pathogens detection,
fish disease diagnosis, and control are discussed
Nanochitosan derived from marine bacteria
Nanochitosans are polysaccharides produced by the alkalescent deacetylation of chitin and comprise
a series of 2‐deoxy‐2 (acetylamino) glucose linked by ß‐(1‐4) glycosidic linkages. These are naturally
formed from the deacetylation of shellfish shells and the exoskeleton of aquatic arthropods and
crustaceans. Reports of chitosan production from unicellular marine bacteria inhabiting the sea, and
possessing distinct animal‐ and plant‐like characteristics abound. This capacity to synthesize chitosan
from chitin arises from response to stress under extreme environmental conditions, as a means of
survival. Consequently, the microencapsulation of these nanocarriers results in new and improved
chitosan nanoparticles, nanochitosan. This nontoxic bioactive material which can serve as an
antibacterial agent, gene delivery vector as well as carrier for protein and drug release as compared
with chitosan, is limited by its nonspecific molecular weight and higher composition of deacetylated
chitin. This chapter highlights the biology and diversity of nanochitosan‐producing marine bacteria,
including the factors influencing their activities, survival, and distribution. More so, the applications
of marine bacterial nanochitosans in transfection and gene delivery; wound healing and drug
delivery; feed supplement development and antimicrobial activity are discussed

Bus Rapid Transit and Socioeconomic Condition of Bus Commuters in Lagos State
Road transport is one of the most common means of transportation across the world. Bus
transportation in Nigeria had witnessed many problems for the past decades considering the growing
population with the attendant loss of lives and properties in most cities like Lagos in Nigeria. This
paper focuses on the adequacy of services provided by Bus Rapid Transit (BRT) in Lagos State with
respect to the extent to which it influences the socioeconomic conditions of bus commuters. It
examines the effect of services rendered by BRT on cost reduction potential, income and safety.
Multistage sampling technique was used to select 20 samples each from all respondents in all local
government area in Lagos State to reach a total of three hundred and thirty (330) samples. The data
collection instrument was the questionnaire which was validated. Data collected were analysed with
the use of descriptive statistics such as means, percentages and standard deviation and inferential
statistics such as regression and analysis of variance techniques. Findings showed that BRT services
has reduced the cost of bus commuters and also increased safety and security thereby increasing the
socioeconomic condition of Lagosians. The study recommends improvements in BRT services
through the deployment of technology as it had been used in developed countries
Transforming the Nigerian Agricultural Sector into an Agribusiness Model – the Role of Government, Business, and Society
This paper proposes that the transformation of the agric sector into an agribusiness model will contribute to repositioning Nigerian economy from its backwater position in the world’s economy. This proposition was investigated with the help of a review of literature and analysis of secondary time series data from the period of 2005–2014, which represented the contributions of the agricultural, manufacturing, oil and gas, and service sectors in Nigeria. One hypothesis was formulated and investigated with the t-test, correlation, and regression tests. The test results were positive and statistically significant at.05 alpha level, and they showed that agriculture has the potential to consistently have a significant effect in contributing to the growth of the Nigerian GDP both in the short and long run. These results justify the clarion call within the government and business sectors to diversify the economy and return to agriculture as the country’s bedrock for economic stability, especially as global economy becomes more volatile, uncertain, turbulent, and ambiguous. To this end, six strategies and twelve policy recommendations are suggested towards the implementation of a Structural Adjustment for Agribusiness Promotion (SAFAP) in Nigeria, and this is to be implemented as an action plan for pursuing a nationwide agricultural revolution. The paper concludes that, in view of its Vision 20:2020 to be among the top twenty economies in the world, Nigeria can become positioned to be a major player in global economy by diversifying from an oil-dependent economy into agribusiness and agric trade
