Effects of Advertising on Consumer Buying Behaviour: With Reference to Demand for Cosmetic Products in Bangalore, India

The study seeks to examine the effects of advertising on consumer buying behaviour considering demand for cosmetic products by residents in and around Nagarabhavi, Bangalore. Using a sample of 100 respondents of mostly the young, we ran regressions and found that advertising does influence expenses incurred on cosmetics products but much influence on the purchase of cosmetic products results from one’s income or pocket money available, and other factors like price of the product, the brand and other people’s recommendation concerning the product. We concluded that, advertising satisfies the needs of the firm and the wishes of consumers. Its role cannot be replaced by any other means. Therefore firms must strategize and know when and where they should advertise. The consumers need to be informed about products and until that is done, the products of firms will still be in stores with no demand for them.

RURAL HOUSING CHALLENGES IN THE UPPER WEST REGION OF GHANA: A CASE STUDY OF KULMASA

Housing is one of the most basic needs of human beings but many people find it difficult to afford. This is why there are many housing shortages in most parts of the world especially in developing countries. There seems to be paucity of studies on rural housing challenges in Ghana in general and Kulmasa community in the Upper West Region of Ghana in particular. This research seeks to bridge this knowledge gap by assessing rural housing challenges in the Upper West Region of Ghana using Kulmasa as a case study area in order to come out with interventions to address these housing challenges. Study methods include the use of questionnaire, interview guides and observation checklist for data analysis. A total of 66 respondents (both male and female) who took part in this study were purposively selected. The results indicated that the existing housing conditions in Kulmasa community in the Wa Municipality of the Upper West Region of Ghana are in substandard state. The study found out that cultural reasons, proximity to place of work, environmental friendliness of the area, accessibility and affordability of the land and availability of better infrastructure are factors influencing housing development in Kulmasa community of the Upper West Region of Ghana. The study found out that lack of access to secure land, limited access to finance, high cost of land registration, slow bureaucratic procedures, lack of infrastructure in rural areas, development controls, uncoordinated policies and implementations, high cost of construction and high price of land are some of the challenges of the existing housing conditions in Kulmasa community of the Upper West Region of Ghana. It is recommended that the government of Ghana should provide enabling environment for private sector to provide safe, adequate and affordable housing for people in rural communities in the Wa Municipality of the Upper West Region of Ghana. Again, the study recommends that the government of Ghana should liaise with banks and set up social housing mortgage scheme for the people of Kulmasa community. This entails interested banks pooling reasonable sum of money together for lending to the people of Kulmasa community at a negotiated but reduced interest rate of say 5% or less.

Remediation Technologies for Polluted Sites: Review

A polluted site can have serious consequences for human health, water supplies, ecosystems, and even building structures, which is why various safeguards have been put in place to address contamination issues. This systematic review will conduct a literature search on remediation technologies for polluted sites. Sources of information and search, eligibility and exclusion criteria, and a systematic searching strategy are used to retrieve articles related to remediation technologies for polluted sites. Heavy metal pollution in the soil is a worldwide problem that humanity is attempting to address. Heavy metal pollution can be found in varying degrees in the soils of all countries worldwide. Heavy metal-contaminated soil is cleaned using chemical, physical, and biological remediation technologies. Many methods have been developed over the last thirty years to remediate oil-contaminated soil. Biological techniques such as phytoremediation and land farming are used to remediate oil-contaminated soil. Groundwater poisoning by heavy metals, which can come from natural soil sources or man-made sources, is a major public health concern. Because contaminated groundwater serves as a source of drinking water for billions of people worldwide, remediation is a top priority. The best remediation technologies for containing groundwater water are pump and treatment, excavation method, permeable reactive barrier, air sparging, electrokinetic remediation, chemical oxidation, and bioremediation. The selection of remediation methods necessitates a thorough examination of technological effectiveness and economic environmental safety. Personal and trial examinations of remediation advancements continue. As a result, in future research, investigating the zero-valent iron powder restoration method in conjunction with other restoration methods to treat soil heavy metal pollution is critical to soil restoration and ecological restoration, revealing the main influencing factors of the restoration process as well as the promotion and implementation of this method.

Controllability of Cardiac Alternans

An arrhythmia is a disorder in the heart that occurs due to irregular or abnormal heartbeats. There are many types of arrhythmias, some of which are harmless, but some, including ventricular tachycardia and fibrillation, can be life-threatening. Certain arrhythmias are preceded by electrical alternans, which is a state characterized by beat-to-beat alternation in cellular action potential duration. Cardiac alternans may arise from instabilities in either voltage or intracellular calcium cycling. Although a number of techniques have been proposed to suppress alternans, most have focused on appropriately adding a new ionic current or adjusting the timing of pacing stimuli based on the difference between recent action potential durations, rather than affecting intracellular calcium directly. In addition, most of the methods proposed to suppress alternans have been tested using models that do not include calcium-driven alternans. Therefore, it is important to establish a theoretical basis for understanding how control methods may apply when alternans is driven by instabilities in calcium cycling. In this study, we apply controllability analysis to a discrete map of alternans dynamics in a cardiac cell. In particular, we compare three different controllability measures to determine to what extent different control strategies can suppress alternans. The modal controllability measure was found to be the most informative measure, with effective variables through which to apply control being action potential duration regardless of alternans mechanism along with sarcoplasmic reticulum calcium load in the calcium-driven alternans case. Moreover, we designed and compared three feedback controllers, with the aim of suppressing alternans, based on our controllability results. As expected, full state feedback methods, such as pole placement and the Linear Quadratic Regulator, were more successful in stabilizing unstable alternans modes compared with feedback based on a single variable. We also conducted preliminary work on analyzing controllability of a different model of cardiac alternans described by nonlinear differential equations. Our study provides insight into the feasibility of controlling alternans driven wholly or partially by voltage or intracellular calcium instabilities

Job embeddedness and turnover intentions: The moderating role of affectivity traits, career stages and perceptions of organisational politics

The study tested the applicability of job embeddedness (JE) theory in Ghana. It also examined moderating effects of affectivity traits, career stage and perceptions of organisational politics (POP) on the JE–turnover intentions relationship. Analyses revealed that composite JE and its dimensions and sub-dimensions (except community fit) were negatively related to turnover intentions. Affectivity traits, POP and career stages moderated the JE–turnover intentions relationship. The study expands the predictive validity of JE to Ghana and adds to the few moderators that have been identified in previous studies. Strategies for increasing managerial employees’ embeddedness and reducing their turnover are proposed
