Competitive business environment organizations are facing today has prompted them to develop business
strategies geared to improve performance in order to sustain competitive advantage. However choice of strategy alone
cannot guarantee performance without considering the role of macro environment in that relationship. The study
therefore sought to establish the moderating effect of macro environment factors on relationship between combined
strategy choices and performance. Over and above the direct effect that moderating factors (macro environment factors)
may have on company performance their moderating effects on the relationship between strategic choice and
performance were tested. Overall, it can be concluded that the four components of company’s macro environment
manifest and affect strategy-performance relationship in varying degrees. The findings imply that companies are
environment dependent and to manage this company-environment interface, an appropriate strategy choice is necessary.
The study also presents a clear link between environment-strategy-performance such that managers of such companies
should consider in enhancing company survival and growth.

The study investigated effects of Corporate Social Responsibility (CSR) on
performance of organizations by focusing on its four fundamental components:
economic, social, political and philanthropic. Using 8 sugar manufacturing firms, the
study findings indicated that corporate social responsibility to have a predictive
power and it could explain variations in firm performance. Ability to explain
variations in company performance was realized through sales volume by 18% (R2 =
0.180), capacity utilization by 16% (R2 = 0.160) while profitability after tax by 20.3%
(R2 = 0.203). Findings of CSR performance results show that though CSR activities
have been viewed to contradict companies‟ ultimate mandate of profit making and
sidetracking organization core activities, statistical results from this study shows
positive performance outcomes especially profitability. This may be attributed to
positive company image and brand as a result of CSR activities.

Nutritional and industrial processes have increased the demand of oils and
this in turn has led to the search for oils from different types of seeds for possible
development and use. It is in this vein that the Tetracarpidium conophorumfruit nuts
were extracted with n-hexane (soxhlet extraction at 650C). The proximate
composition,antinutrient and mineral content of freshly harvested Tetracarpidium
conophorum(African walnut)seed from 4 weeks after anthesis (WAA) to fruit
maturation were assessed in this study. Data obtained for the proximate composition
at matured stage of fruits developmentrevealed significant high amount of
fat(43.4±0.82) %; moisture(36.7±1.39) %; crude protein(30.1±1.38) %; carbohydrate
(16.91±1.07) %;low crude fibre (2.59±0.64) %, and ash content(7.3±0.07) %[which
contained higher amount ofminerals such as of Fe (130.81 ± 3.8) ppm, Mn (40.11 ±
1.00) ppm, Ni (2.92 ± 0.81) ppm, and Cu (12.01 ± 0.71) ppm, decrease inCa (1.082
± 0.08) %, Cr and Cd were not detected throughout the period] at 20 WAA compare
to immature stages of 4, 6, 8, 10, 12, 14 and 16 WAA. The level of antinutrientfactors
are oxalate (0.46±0.05) mg/100g; Phytate (29.2±0.44) mg/100g and cyanogenic
glycosides (0.17±0.07) recorded lower content, except tannins (90.5 ±3.93)
mg/100gwhich recorded significant (p < 0.05) higher content at 20 WAA when
compared with immaturestages in 4, 6, 8, 10, 12, 14 and 16 WAA. This study
revealed the nutritional profile of the fruitnut as good sources of plant protein,
carbohydrate and fat, with reduction in the level of some anti-nutrients in matured
fruits which are potentials that could be exploited by food and pharmaceutical
industries.

In a preliminary research, the authors reported that solvents extracts of Alstonia boonei (Egbu) possess strong antimalarial activity against NK-65 Chloroquine sensitive Plasmodium berghei infected mice with aqueous extract having the highest decrease in mean percentage parasitaemia. This research is therefore aimed at evaluating the acute and sub-chronic toxicity of solvents extracts of the plant on kidney. The (LD50, oral) was conducted in two phases. In the first phase, oral doses of 10, 100 and 1000 mg/kg body weight of the extracts were administered and mice observed for sign of toxicity and death. In the second phase, 1600, 2900 and 5000 mg/kg body weight of the extracts were administered and signs accompanying toxicity and possible death of animals were also monitored. Sub-chronic toxicity studies were carried out to assess the effect of the solvents extracts on kidney function indices after 28 days of oral administration of the extracts at 150, 250 and 500 mg/kg body weight. The (LD50, oral) of all extracts was found to be greater than 5000mg/kg which is practically non- toxic according to standard scale of toxicity. The result of sub-chronic toxicity study showed a significant increase (P<0.05) in mean levels of creatinine, urea and serum electrolytes in all extracts administered groups in a dose dependent pattern compared to normal control. However, histopathological analysis of the kidney tissues shows no pathological changes between test groups and normal control. Thus, solvents extracts of Alstonia boonei modifies biochemical parameters (Crea, Urea and Electrolytes) but within the context of duration of this research, no significant pathology was observed in kidney tissues. Alstonia boonei stem bark should be used with caution

The antioxidant properties of oil and fruit extracts of Tetracarpidium
conophorum (African walnut) from four weeks after anthesis(WAA) to fruit
maturation were assessed in this study. The oils from the fruits were extracted with
chloroform-methanol 1:2 (v/v), and the methanol extracts of the fruit seeds were also
prepared using standard procedures. The in vitro antioxidant capacity of the fruits and
oil extracts was determined by spectrophotometric methods using 2, 2-diphenyl-1-
picrylhydrazyl (DPPH) radical, H2O2 and malondialdehyde (MDA) assays. Results
from the study indicated that DPPH and H2O2 scavenging capacity as well as
percentage inhibition of MDA were significantly (P˂0.05) higher inoil 20 WAA
(48.34±0.12%,46.9±1.03%,53.5±0.46%)and whole fruit extracts at 20 WAA
(31.84±0.33%, 19.0±1.12%, 51.7±0.26%) respectively,but with significant (P˂0.05)
lesser percentage of inhibition at 4-12WAA in both the oil and the whole extracts.
The hepatoprotective effects of the extracts were examined in vivo in male wistar rats
challenged with sodium arsenate. Results showed that the rats fed with the oil and
whole fruit extracts had significant reduction (p<0.05) in lipid peroxidation, increase
in superoxide dismutase (SOD) and catalase (CAT) activities especially at 16-20
WAA relative to control values. African walnutextracts treated rats also showed
similar decrease in serum AST (122.7±2.58U/L), ALT (59.1±2.49U/L), ALP
(20.4±0.15U/L) and GGT (229.0±0.36U/L) levels at 20 WAA when compared to 4
WAA extracts treated rats, AST (129.3±0.64U/L), ALT (72.3±2.59U/L), ALP
(34.4±0.08U/L) and GGT (299.7±1.27U/L). The results suggest that the various fruit
extracts possess varied degrees of potent antioxidant activity both in vitro andin vivo
and may serve as important sources of antioxidants in food, cosmetics and
pharmaceutical industries.

This study aimed to highlight on the influence of exposure to electromagnetic fields (EMFs) on the
cardiovascular system in humans and experimental animals, from the recent articles regarding the cardiovascular effects
of exposure to EMFs. EMFs might produce a variety of adverse in vivo effects such as heart problems, chest pain, and
cardiovascular system disorders. Previous studies showed that an association between elevated magnetic field exposure
and mortality of employer in electric utility industry jobs from arrhythmia-related causes and acute myocardial infarction
influence heart rate variability by changing autonomic balance. EMF exposure can affect structure and function of
cardiovascular system and may facilitate myocardial infarction by nuclear changing of cardiomyocytes. Exposure to
EMFs induced pain or pressure in the chest area, heart palpitations, and/or an irregular heart beat. The symptoms
resemble a heart attack and thus contribute to even more anxiety. Also, exposure to EMFs caused highly significant
increases in the activeties of serum creatinine phosphokinase, lactate dehydrogenase and aspartate amino-transferase
enzymes, and decreases in plasma calcium level and total anti-oxidant capacity. Rats exposed to EMF showed increases
in blood pressure, the absolute and relative whole heart and left ventricular weights. On the other hand, the heart rate was
significantly reduced in rats exposed to EMF.

Tasting salt or Monosodium Glutamate was invented by the Japanese over a century ago. The flavour profile
known as Umami, or the fifth taste, after the four tastes of sweet, salty, sour and bitter, was discovered whilst working
with sea weed. Umami is a meaty taste that is naturally present in cheese and ripe tomatoes. For more than a 100 years,
the flavour of Umami has been artificially manufactured in factories all over the world, starting in Japan. The flavour
profile presented by tasting salt offers both packaged and non-packaged food producers with an affordable and openly
accessible alternative to flavouring their foods. Home cooks are also offered the product as they are able to openly
purchase the salt off the shelf. Hence, a lack of regulation. Presently, tasting salt is present in thousands of food items all
over the world, and its use is only increasing. Restaurants use the salt in their dishes as an inexpensive alternative to
building complex flavour profiles using meat stock. At the same time, health concerns about the product‟s wide spread
use have also been made apparent over the last two decades. Despite the legal system of almost all countries in the world
not having put any restriction on tasting salt, the use of the product has been shown to lead to serious health concerns for
humans. Hence, the need for ethical business practice to promote public health by going above and beyond legal
compliance.

The significance of effective leadership and management for the successful
operation of schools and colleges has been increasingly acknowledged in the 21st
century. The trend towards self-management in the United Kingdom and in many
other parts of the world has led to an enhanced appreciation of the importance of
managerial competence for educational leaders. Today, leadership is seen as central
and essential to delivering the changes, improvement and performance that
community increasingly expects of all organizations including schools. The changing
manner of school management has undoubtedly created reforms in the field of
education with change expressed in the evolution from exterior supervision of school
work to the empowerment of school’s staff, principal’s and teacher’s roles. This study
was initiated to look into the leadership style among school principals in governing
school systems in Peninsular Malaysia. Secondary data consisting of various
leadership styles used in administering teachers, transformational and transactional
leadership and the correlation between leadership styles and organizational variables,
relationship between value systems and school principal’s principles were performed.
Numerous researches have highlighted the fact that leadership behavior is a predictor
of its efficacy and leads to the examination of leadership evolution. In this study,
leaders with a high moral value system tend to lean towards a transformational
leadership style in governing school systems in Peninsular Malaysia and
acknowledges a positive correlation between leadership styles and value systems in
school administration.

Chronic Periodontitis is considered to be common dental disease with high
tooth mortality as well as morbidity. Reports from different places around the world
showed a prevalence of severe periodontitis in around 8-10% of the Population;
Sweden 8%, England 7%, The Netherland 10%, Italy 9.6 % and Srilanka 8 %. The
aim of the survey was to estimate the prevalence of chronic periodontitis among Saudi
nationals in Aljouf Province, Kingdom of Saudi Arabia. 310 subjects were selected by
stratified cluster sampling technique. They were examined in preselected areas of
Aljouf region by using community periodontal index of treatment need. The impact of
known risk factors for periodontal disease, e.g., oral hygiene habits, age and smoking.
53% of the subjects and 15.8% of the sextants. Shallow pockets were observed in
39.4% of the subjects and 38.4% of the sextants. Calculus was found to be present in
9.8% of the subjects and 48.8 % of the sextants. Calculus was maximum (53%) in
group I (30-40 years) and minimum (21%) in Group IV (60 years and above).
Periodontal disease was found to be highly prevalent in the study population (90%)
and the periodontal treatment needs increased with advancing age. Nationwide surveys
are recommended to assess the periodontal disease which helps in planning prevention
and treatment of periodontal diseases.

Scientific discoveries put forth new trends in the education during modern
times. These trends influenced all aspects of human society. Scienticism is considered
modern day religion, ideology and are more relevant and applicable for contemporary
society. The perception, all matter being composed of small, indivisible particles
called atoms is the base of matter, from which every object has its existence. From its
earliest in the second century of the hijra, kalam has always been enthralled with the
theory of atoms. In this paper an attempt has been made to discuss, elaborate and
analysis with certain divergence the issue of atomism. The broad theory was generally
endorsed by both the Mu‟tazilite‟s and Ash‟arites and their views, difference of
opinion on the said issue, along with other medieval Muslim Scholars will be
discussed at length. Their concept about the role of atom in matter formation in early
Muslim scholar writings will serve the base for this paper.

10.21276/sjhss.2017.2.9.4
This research paper analyses the impact of knowledge creation process on
Mauritian business from a case study perspective. The knowledge creation process is
a dynamic one since it comes from diverse areas. Firstly, the university or any
training institution develops business courses that would help students benefit from
job opportunities in firms which expected them to apply their knowledge at work. On
the other hand, the knowledge creation process might come from the firm that urges
the graduate to develop his knowledge and capabilities that should directly impact on
the business. There is also a new approach whereby the university develops courses
by integrating the student with the industry in a programme tailor-made for the
organisation. This paper states that knowledge creation process should be developed
in a dynamic way that integrates and addresses business needs in today‟s fast
changing environment. Through a case study approach in three selected situations,
using Nanoko‟s Taxonomy of knowledge creation as a framework, it reveals that the
knowledge creation process is a two-fold dynamic practice and that its success
depends on the inter-relationship between tacit and explicit knowledge.

There are various grafting materials used for socket preservation of the
alveolar ridge following tooth extraction. The purpose of this study was to evaluate
clinically and histomorphometrically healing after tooth extraction with or without
placement of a synthetic bone graft and determine the effect on alveolar ridge
preservation following extraction. 30 subjects in need of extraction of non-molar teeth
were recruited for this study. Recruited subjects were randomly assigned to the group
A (with graft material) or control (without graft material) group B. Data were recorded
at 6 months after socket preservation procedures. At 6 months, a surgical re-entry was
performed; Clinical Measurements and bone core biopsies were obtained for
histomorphometric analysis. The control group B had a mean reduction in ridge height
of 1.26mm, whereas alveolar ridge height in the test group A was 0.73mm. The test
group A was 7.33 ± 1.01 mm compared to 7.23 ± 1.13 mm in group B which were not
statistically significant (p = 0.684). Histomorphometric analysis revealed total new
bone volume in group A represented 65.6 ± 11% connective tissue 25.6 ± 10.18 %
and 8.8% was occupied by residual graft material. The mean new bone volume in
group B was 31.23 ± 7.24%, whereas connective tissue formation was approximately
68.78 ± 7.24 %. Both these values were statistically significant when compared with
group A. There was no relation with residual graft material as there was no graft
material used in group B. A positive response was observed when synthetic graft was
applied to extraction sockets, suggesting that it may be useful for preservation of ridge
height prior to dental implant placement.

Education has been directly equated with the overall development process
of any human society. Basic or primary education being the foundation, is necessary
not only for the sake of basic literacy and numeracy, but because it prepares children
or human for future challenges. The more adequate and qualitative the primary
education is given to children, the more equipped and industrious the children would
become in the future. Therefore, good administrative planning and provision of
primary level of education is crucial in achieving educational development. This
paper examines Universal Basic Education (UBE) as a programme designed to
provide primary education, outline it`s policy thrust and nature of implementation as
well as assessing the ways through which the scheme can tackle the educational
challenges facing the country, for an achieved sustainable development. Secondary
data was used comprising the UBE documents and various litratures written by
scholars on education and development in order to analyse and assess the relationship
between basic (primary) education and sustainable development in Nigeria.
