Building materials costs increases and sustainability in real estate development in Nigeria

Abstract: Sustaining real estate provision is vital in order to diminish the inaccessibility of housing to citizens, and is one of the best proactive and innovative measures to improve housing estates against the deficit challenge prevailing in Nigeria. This study examines the factors and effects of increasing costs of building materials in real estate development sustainability in Nigeria. The study found that eleven dynamics were significant to contributing to the widespread deficits, deplorable conditions and inaccessibility of housing units' to people. The study further indicates that these factors also underscore the ever increasing rent of residential properties in the area. The study reflection should greatly assist in depicting better ways of tackling these issues so that reductions in the impact of building materials cost increases on real estate provision as experienced in practice can be sustained within the system. A 'think tank' effort is recommended for relevant stakeholders.

Physical Evidence and Customer Patronage: An Empirical Study of Nigeria Banking Sector

Abstract: This study examines the impact of physical evidence on customer patronage of quoted Banks in south-south zone of Nigeria. 14 quoted Banks at the Nigeria Stock Exchange Market were used for the study. The research considered firm level of analysis and top managers unit of analysis. Customers of the chosen banks were also used. By this arrangement, 42 managers and 7 customers randomly selected constituted our respondents for the study. Descriptively, the study variables were presented and inferentially, the Spearman Rank Correlation Coefficient was used in testing the various hypotheses. In addition, we employed the Pearson Partial Correlation to ascertain the extent to which the organizational factors mediate the relationship between physical evidence and customer patronage. The result of the analysis showed that there is a strong positive and significant correlation between physical evidence and customer patronage. The study specifically revealed that efficient design of work place ambience; physical architecture and signs Original Research Article Adiele et al.; BJEMT, 7(3): 188-199, 2015; Article no.BJEMT.2015.083 189 significantly impact on sales volume, profit margin and customer retention. It was further found that organization size and information technology capability strongly mediated the relationship between the predictor and criterion variable. The study therefore concluded that physical evidence significantly affects customer patronage. Hence, it was recommended that the panacea to poor customer patronage is predicated on the bank’s ability to efficiently adopt physical evidence dimensions used for the study as significant conditioning factors of the business environment.

Organizational citizenship behaviour: a critical review of its development in a diversity driven workplace

Abstract: This paper theoretically reviewed the concept of OCB and its implication on a diverse workplace environment. In doing this, the paper identified the theoretical framework on which the concept of OCB is built upon through its sociological and psychological perspective. From that a critical assessment of development of OCB was determined as well as its various dimensions. In order to establish the influence of diverse workforce in the workplace, we also X-rayed the concept of diversify and identify the different forms in which an organization could be said to be diversity driven with critical focus on deep and surface level. In the course of extant literature exploration, we discovered that diversity is an important aspect of today’s modern organization’s strategy to remain competitive and innovative in its operational life as it affords them with different breeds of employees with higher potentials for behavioral tendency such as OCB. Finally we looked at the implications of diversity on OCB and consequently make recommendations based on our conclusion.

Soil quality around a solid waste dumpsite in Port Harcourt, Nigeria

Abstract: The levels of soil parameters and selected heavy metals around a solid waste dumpsite receiving untreated wastes from all sources and a control site within Port Harcourt, Nigeria have been examined. Top soil (0–15 cm) and sediment samples were collected and analysed for pH value, particle size, total nitrogen, potassium, available phosphorus, organic matter, effective cation exchange capacity, cadmium, nickel and lead using standard methods. The results showed that the waste dump contributed to the high levels of nutrients and heavy metals. The dry season mean concentrations were: organic matter (5.28 ± 1.34% or 132,422.4 kg ha−1), K (1.60 ± 0.52 meq per 100 g), N (0.09 ± 0.06% or 2257.2 kg ha−1), Av.P (15.11 ± 7.57 μg g−1), Cd (1.34 ± 0.72 μg g−1), Ni (4.10 ± 1.63 μg g−1) and Pb (38.85 ± 22.18 μg g−1) while the wet season mean concentrations were organic matter (5.46 ± 1.39% or 136,936.8 kg ha−1), K (2.79 ± 0.81 meq per 100 g), N (0.10 ± 0.05% or 2508 kg ha−1), Av.P (9.22 ± 2.69 μg g−1), Cd (1.72 ± 1.22 μg g−1), Ni (14.95 ± 14.94 μg g−1) and Pb (53.50 ± 40.09 μg g−1). There was efficient mineralization process in the area. The texture of soil on the main dumpsite was loamy sand, which suggests that the ground water in the area is susceptible to contamination by surface pollutants. The texture of soil at the control site is sandy loam while sediment has the textural class of sand. Decomposed organic materials and agricultural activities influenced the texture of soils. The soils from the main dump and sediment were slightly alkaline while the control soil was moderately acidic. In both seasons, a significant variation exists (P < 0.05) between the metal concentrations in soil at the main dump and those in the sediments with a positive correlation (r = 0.572149) in the wet season and (r = 0.956647) in the dry season. The presence of liming materials and activities of microorganisms on the waste dump increased the pH of the soils. The accumulation of nutrients results in the luxuriant growth of plants/crops on the waste dump. Resume Le niveau de divers parametres et le taux de certains metaux lourds ont ete examines autour d'une decharge qui recoit des dechets solides non traites de toutes origines et sur un site de controle dans Port Harcourt. On a recolte des echantillons de la partie superieure du sol (0 a 15 cm) et des sediments et on les a analyses pour connaitre le pH, la taille des particules, l'azote total, le potassium, le phosphore disponible, la matiere organique, la capacite effective d’echange de cations, le cadmium, le nickel et le plomb, en utilisant des methodes standards. Les resultats ont montre que la decharge contribuait aux taux eleves de nutriments et de metaux lourds. Les concentrations moyennes en saison seche etaient: matieres organiques (5,28 ± 1,34% ou 132.422,4 kg ha−1), K (1,60 ± 0,52 meq per 100 g), N (0,09 ± 0,06% ou 2.257,2 kg ha−1), P disp. (15,11 ± 7,57 μg g−1), Cd (1,34 ± 0,72 μg g−1), Ni (4,10 ± 1,63 μg g−1) et Pb (38,85 ± 22,18 μg g−1), tandis qu'en saison des pluies, les concentrations moyennes etaient pour les matieres organiques (5,46 ± 1,39% ou 136.936,8 kg ha−1), K (2,79 ± 0,81 meq/100 gr), N (0,10 ± 0,05% ou 2.508 kg ha−1), P disp. (9,22 ± 2,69 μg g−1), Cd (1,72 ± 1,22 μg g−1), Ni (14,95 ± 14,94 μg g−1) et Pb (53,50 ± 40,09 μg g−1). Il y a un processus efficace de mineralisation dans la zone. La texture du sol de la decharge principale est un sable riche, ce qui suggere que l'eau souterraine est sensible a la contamination des polluants de surface. La texture du sol du site de controle est un terreau sableux alors que les sediments ont une texture de la classe des sables. Les matieres organiques decomposees et les activites agricoles influencaient la texture des sols. Les sols de la decharge principale et des sediments etaient legerement alcalins alors que le sol de controle etait moderement acide. Pendant les deux saisons, il existe une variation significative (P < 0,05) de la concentration du sol en metaux entre la decharge principale et les sediments, avec une correlation positive (r = 0,572149) en saison des pluies et (r = 0,956647) en saison seche. La presence de residus de chaux et l'activite des microorganismes sur la decharge ont augmente le pH des sols. L'accumulation de nutriments a comme consequence la croissance luxuriante des plantes et des cultures sur la decharge.
