Adherence to Islamic principles of success and academic achievement

This study was conducted in order to investigate the possible relationship between adherence to Islamic principles of success and academic performance of university students. Accordingly, a questionnaire based on Islamized principles of success (referred to as “Islamic character quotient inventory (ICQi)”) was correlated with CGPA (Cumulative Grade Point Averages) of 343 students of Usmanu Danfodiyo University, Sokoto. The empirical testing indicates that the total score on ICQi correlated positively and significantly with the academic performance of the respondent. Students with either high or medium adherence to ICQi have a significantly higher CGPA than their counterparts with the low-adherence level. However, the result did not show a significant relationship between the CGPA of highly adherent individuals and that of those with medium adherence level. The findings of this research may suggest that Islamic principles are not confined to the spiritual aspect of human’s life, but also relevant and useful for our mundane affairs

INDUSTRIAL RELATIONS ENVIRONMENT IN NIGERIA: REVIEWING CONFLICT CAUSES AND TAXANOMIES AMONG PUBLIC SECTOR EMPLOYEES

The institutional and legal framework of bargaining that has been established in Nigeria can be seen as encapsulating the shape, rather than the substance, of meaningful industrial relations. As such, it closely corresponds to the broader disagreement existing in other areas of social life between the constitutional, legal, and normative mores inherited from the colonial government and real behavior patterns. The main issues that divide wage earners, on the one hand, from employers and government, on the other, have an existence far alienated from the recognized system of industrial relations, while the unions, the employers, and the government continue to give formal adherence to the system. As a response to the need to resolve issues between employers and their workers speedily, the Industrial Arbitration Panel [IAP] was established in 1976. The Act which was established vested the Panel with jurisdiction to hear and determine trade disputes between workers and employers, including inter and intra Union disputes in both private and public sectors of Nigeria. The paper seeks to review the industrial relations environment in Nigeria. It emphasizes on how conflict and its taxonomies shapes the behavior of public sector employees. The paper equally concludes that the causes of conflict among public sector employees is greatly influenced by the inter-play of institutional, political and legal factors within the industrial relations environment.  Article visualizations

The Effect of Trichlia emetica Leaf Extract on the Flammability of Flexible Polyurethane Foam

Due to the health and environmental consequences of conventional flame retardants the incorporation of new plant based flame retardants becomes imperative. Hence the choice of the leaves of Trichlia emetica as a flame retardant on flexible polyurethane foam based on Hausa folklore tradition that it is used as a flame retardant. Analysis of the treated flexible polyurethane foam revealed that add on percentage ranged from 9-21%, Ignition time between ranged within 6-14 sec, flame propagation rate 0.42-0.22 cm/s, after glow time decreased from 12 sec to 2 sec and char formation increased from 18% to 26%. Which indicated a modification of the flammability characteristics of the flexible polyurethane foamKeywords: Add on, After glow, Char, Flame propagation rate, Flame retardants, Ignition time, Polyurethan

Analisis Kesuburan Perairan Sekitar Muara Sungai Tuntang, Morodemak Berdasarkan Hubungan Antara Nilai Produktivitas Primer Dengan No3 Dan Po4

Produktivitas primer merupakan deskripsi kuantitatif yang menyatakan kesuburan perairan, juga pemanfaatan konsentrasi unsur hara yang terdapat di dalam suatu badan air melalui laju pembentukan senyawa-senyawa organik. Nutrien sangat dibutuhkan oleh fitoplankton untuk perkembangannya dalam jumlah besar maupun dalam jumlah yang relatif kecil. Setiap unsur hara mempunyai fungsi khusus pada pertumbuhan dan kepadatan tanpa mengesampingkan pengaruh kondisi lingkungan. Unsur P dan N sangat penting untuk pembentukan protein. Tujuan penelitian ini adalah untuk mengetahui kandungan ortofosfat dan nitrat di sekitar muara sungai Tuntang; dan mengetahui hubungan antara ortofosfat, nitrat dan produktivitas perairan di muara sungai Tuntang, Morodemak.Penelitian ini dilakukan di 7 lokasi sampling perairan sekitar muara sungai Tuntang, Morodemak dan berlangsung antara 22 dan 29 Mei 2014. Pada penelitian ini diukur nilai kandungan nitrat dan ortofosfat serta nilai produktivitas primer. Analisis perbedaan kedalaman nitrat dan ortofosfat menggunakan uji chi-kuadrat.Nilai kandungan nitrat di lapisan permukaan berkisar antara 0.6– 1.6 mg/L dan lapisan dasar berkisar antara 0.6 – 2.5 mg/L. Nilai kandungan ortofosfat di lapisan permukaan berkisar antara 0.1 – 0.24 mg/L dan lapisan dasar berkisar antara 0.17 – 0.48 mg/L. Nilai produktivitas perairan berkisar antara 112.608 – 319.056 mg/C/m3/hari sehingga lingkungan muara dikategorikan mesotrofik.Terdapat hubungan kuadratik antara nitrat, fosfat dan produktivitas primer, diketahui NO3 optimum terjadi pada kadar 1.12 mg/l dan PO4 optimum terjadi pada kadar 0.168 mg/l. Primary produtivity is a quantitative description that stated tropic water status as well as the utilization of nutrients in waters through formation rate of organic matters from anorganic matters. Nutrients are needed by phytoplankton to grow in large as well as relatively small number. Every nutrients has a special function in phytoplankton growth and density without exclusionthe influence of environmental conditions. N and P are very important element to the formation of proteins. The purpose of this study wereto determine the orthoposphate and nitrate content in the Tuntang river estuary; and to determine the relationship of nitrate, orthoposphate and water productivity in Tuntang river estuary, Morodemak.

A Report of At-Scale Distribution of Chlorhexidine Digluconate 7.1% Gel for Newborn Cord Care to 36,404 Newborns in Sokoto State, Nigeria: Initial Lessons Learned.

With an annual estimated 276,000 neonatal deaths, Nigeria has the second highest of any country in the world. Global progress in accelerating neonatal deaths is hinged to scaled-up interventions in Nigeria. We used routine data of chlorhexidine digluconate 7.1% gel utilized by 36,404 newborns delivered by 36,370 mothers, to study lessons associated with at-scale distribution in Sokoto State, North West Nigeria.Under state government leadership, a community-based distribution system overseen by 244 ward development committees and over 3,440 community-based health volunteers and community drug keepers, was activated to deliver two locally stored medicines to women when labor commenced. Newborns and their mothers were tracked through 28 days and 42 days respectively, including verbal autopsy results. 36,404 or 26.3% of expected newborns received the gel from April 2013 to December 2013 throughout all 244 wards in the State. 99.97% of newborns survived past 28 days. There were 124 pre-verified neonatal deaths reported. Upon verification using verbal autopsy procedures, 76 deaths were stillborn and 48 were previously live births. Among the previous 48 live births, the main causes of death were sepsis (40%), asphyxia (29%) and prematurity (8%). Underuse of logistics management information by government in procurement decisions and not accounting for differences in LGA population sizes during commodity distribution, severely limited program scalability.Enhancements in the predictable availability and supply of chlorhexidine digluconate 7.1% gel to communities through better, evidence-based logistics management by the state public sector will most likely dramatically increase program scalability. Infections as a cause of mortality in babies delivered in home settings may be much higher than previously conceived. In tandem with high prevalence of stillborn deaths, delivery, interventions designed to increase mothers' timely and regular use of quality antenatal care, and increased facility-based based delivery, need urgent attention. We call for accelerated investments in community health volunteer programs and the requisite community measurement systems to better track coverage. We also advocate for the development, refinement and use of routine community-based verbal autopsies to track newborn and maternal survival
