Abstract

The objective of this study was to determine the pulping and paper making potentials of oil palm (E guineensis). Fibrous material from the whole trunk (WT), empty fruit bunch (EFB, fronds (FDS) and depithed trunk (DT) were evaluated using proximate chemical analysis, fiber morphological and related characteristics. Effect of active alkali (AA) % as Na2O on kraft pulping properties and the handsheet paper propertie was studied. Proximate chemical analysis reveal acceptable cellulose content for EFB (43.51%), FDS (51.13%) and DT (53.80%) while WT (32.44) is unacceptable. Low lignin content obtained (17.8−21.8%) suggests easier pulping characteristics. The high % NaOH solubility of WT (26.05%) and FDS (32.1%) suggest potential of high effluent loads. Fiber morphological studies revealed that approximately 83% of fibers are ≤ 1.5 mm in length thus putting oil palm as a short fiber source. The slenderness ratio ranges from 33.44 to 82.80; Runkelratio from 0.40 to 0.63; flexibility co-efficient from 57.20 to 71.46 and rigidity co-efficient from 0.29 to 0.43. Studies of pulping properties reveal that as active alkali % was increased the percentage total pulp yield, % screened pulp yield, % screened rejects, pulp kappa number, klason lignin and tear index of resultant pulp/handsheet all/each decreased. Conversely, as active alkali % was increased the Brust index, double fold number, breaking length, tensile index of paper handsheets and pulp brightness were each enhanced. It was concluded that in pulping of WT AA% should be < 14 and EFB pulping should be ≤ 14 in order to have acceptable yield. Also in order to have acceptable tear index, AA% should be ≤ 16. It is being recommended that trunks should be depithed in order to have acceptable yield. The fibrous material from oil palm make acceptable raw material for paper making and are good hardwood substitutes. Paper produced when bleached can be used for printing and writing papers while the unbleached grades can be used for wrapping and package papers and for corrugated boards.

Abstract

Cement bonded composites of 1250 kg/m3 were made in the laboratory either as single layer composed of exclusively oil palm empty fruit bunch (EFB); Tropical hardwood sawmill residue (THSR) or randomly mixed particles (40% of EFB and 60% of THSR oven dry wt/wt) OR of 3-layer composed of 1:2:1 ratio (for face layer of THSR; core layer of EFB and back layer of THSR particles, wt/wt, respectively). Composites were produced at 4 levels of CaCl2 addition (0, 1, 2 and 3% wt/wt based on cement wt) and 6 levels of initial water content of the cement/aggregate mixture (2.5:1:0.5; 2.5:1:1; 2.5:1:1.5; 2.5:1:2; 2.5:1:2.5 and 2.5:1:3; ratio wt/wt based on cement wt plus oven dry wt of particles). Proximate chemical analysis of representative samples reveal hollocellulose content (77.35 and 74.11%); a-cellulose (43.51 and 52.01%); Hemicellulose (22.9 and 20.2%). Lignin (17.8 and 22.5%); Ash (0.91 and 1.85%) and solubility in Alcohol-benzene (1.6 and 3.98%); cold water (2.42 and 3.15%); Hot water (2.93 and 5.06%); and 1% NaOH (23.4 and 26.11%) respectively for EFB and THSR. Also Morphological studies reveal mean fiber length (1.06 and 1.18mm); Fiber diameter (11.75 and 17.40μm), slenderness ratio (55.79 and 35.98) and Rigidity co-efficient (0.38 and 0.47) respectively for EFB and THSR. The above make both particle sources suitable substitutes for virgin fiber/particles from hardwoods. A total of 192 composites were made representing two panels per production mix. Composites were sampled and tested in accordance with provisions of ASTM D1037-2007. Composite properties ranges are MOR (2.61–20.81 MPa); MOE (2180–5764 MPa); IB (0.28–0.75 MPa). WA (16.41–28.11%) and TS (1.26–5.98%). Properties were evaluated and only production mix that met both the requirements of International Organization for Standardization (10S 8335–1987) and Malaysian Standard Institute (MS 934–1984) were recommended. Acceptable composites were produced from production mix of initial water content ≥1.5 or 30% (based on cement wt + oven dry wt of particles, wt/wt) and 2 or 3% CaCl2 additive in case of single layer composites while ≥ 2 or 36.36% of initial water content is required in 3-layer composite using same additive level. The effects of furnish type and composition, additive level and initial water content on properties were all found significant (P > 0.01) in factorial analysis.

Abstract

Purpose

The purpose of this paper is sixfold: first, to know the ability of area carrying capacity to the development of downstream oil palm industry; second, to know the potential for the development of downstream oil palm industry in efforts to improve the community through employment and business opportunities in the regions; third, to find eco-friendly institutional arrangement strategies of oil palm farming in order to spur economic growth and development; fourth, to formulate strategies for potential environmental impact as a result of institutional arrangement and development of downstream oil palm industry, both in regional and national scope; fifth, to predict the economic multiplier effect as impact of institutional arrangement and development of oil-palm-based downstream industry; and sixth, to include production centers and development areas of oil-palm-based downstream industry in potential areas.

Design/methodology/approach

Research location was in potential areas of oil palm plantation development, either in the form of plasma through state-owned enterprises (BUMN) and private-owned enterprises (BUMS), or in the form of self-supporting by community. The research locations were divided into two parts, namely the land area and the coastal area. The land area of Riau consisted of Kampar, Rokan Hulu and Kuantan Singingi Regency, while the coastal area of Riau consisted of Pelalawan, Siak, Bengkalis, Indragiri Hilir, Indragiri Hulu and Rokan Hilir Regency. Both research areas had different productivity which was caused by differences in soil fertility. The required data were primary and secondary data.

Findings

Plantation activities have increased the mobility of goods in the villages, causing plantation activities to also open business and employment opportunities for people who are able to accept these opportunities. Since post-1998 crisis, the growth of oil palm plantation area in Riau increased sharply, namely in 1998, the area of oil palm plantations was 901,276 ha, in 2012, 1,119,798 ha and increased to 2,103,175 ha at the end of 2017. Through economic activities that produce goods and services required during the plantation process and the development, downstream industries will have backward linkages. The development of oil palm plantations in Riau has had an impact on economic activities in rural areas. The result of the research in the field is that the average income of farmers in the plantation subsector (especially oil palm) is Rp4,576,696 per month or $5,781.09 per year. The impact on investment in the estate subsector has been felt by rural communities. This condition also affects the purchasing power of the people, resulting in the increase of mobility of goods and people. During the period 2009–2016, rural communities enjoyed a high level of prosperity. During this period, the price of fresh fruit bunch at the farm level was quite profitable. On the other hand, the production of the plantation area also increased compared to the previous period. The impact of rising prices and increasing production of farmers is that the farmers’ welfare index in the countryside had a positive value of 0.43. This index showed the increase of farmers’ welfare from the previous period by 43 percent.

Originality/value

There are few previous studies which have comprehensively and specifically reviewed the regional economic empowerment through institutional arrangement and development of oil-palm-based downstream industry. The development of oil palm plantations aims to eliminate poverty and underdevelopment, especially in rural areas. In addition, it also pays attention to equity. In broad sense, agricultural development which is based on plantations aims to improve the welfare of the community so that there is a change in the pattern of life of the surrounding community. On the other hand, the success of plantation development that is based on oil palm agribusiness is expected to reduce income inequality between community groups and between regions.

Abstract

Purpose

The purpose of this paper is to develop strategies for potential environmental impacts as a result of institutional arrangement and development of oil palm downstream industry both regionally and nationally.

Design/methodology/approach

The research location is in the areas potential for oil palm plantation development, either by plasma through BUMN and BUMS or self-supporting by the society. The research location will be divided into two parts, namely, the land area and the coastal area. The Riau land areas are Regency of Kampar, Rokan Hulu, and Kuantan Singingi, while Riau coastal areas are Regency of Pelalawan, Siak, Bengkalis, Indragiri Hilir, Indragiri Hulu and Rokan Hilir. Both research areas have different productivity due to the different soil fertility levels. The sustainability level of oil palm plantation from the socio-economic and environmental aspects is analyzed using the multi-dimensional scaling approach modified into Rapid Appraisal-Index Sustainability of Palm Oil Management.

Findings

In Riau Province, the development of oil palm is quite rapid. This is reasonable for several reasons which include the following supporting factors: the geographical condition of the Riau region is very supportive; the high demand for palm oil derivative products; the existence of market guarantee for oil palm farmers; the higher income oil palm generates than other plantation crops; and the relatively flat area. Most of the problems faced by oil palm farmers are the use of less good seeds, the length of the fruit laying at the location of the plantation, the inadequate production road, the relatively far distance to palm oil mill (POM) (National Agency of Drug and Food Control), the tendency of determining the unilateral revenue of the POM, the collectively measurement of revenue and the general revenue information. The development of oil palm plantations has created an entrepreneurial capability for farmers who are able to capture business opportunities in the agricultural sector, especially the plantation sub-sector.

Originality/value

The originality of this paper shows the comprehensively control strategy, potential of environmental impact and palm oil plantation. The method used for data collection was rapid rural appraisal method because accurate information is needed in a limited time as it relates to decisions related to village development that must be taken immediately. The study area was conducted in Riau Province because Riau Province is one of the biggest palm oil producers in Indonesia. The study sites will be divided into two, namely, the land area and the coastal area.

Abstract

Multiple sclerosis (MS) is a chronic condition with variable physical, cognitive, and quality of life impacts. Little research has investigated how MS outcomes vary by social identity (race, gender, disability, age, sexual orientation, and nationality) and social location (place within systems of power and privilege). However, emerging evidence points to racial and ethnic group disparities in MS outcomes. This chapter integrates core concepts from the life course perspective and an intersectional feminist disability framework to interrogate the role of diagnosis pathways in determining differential MS outcomes. MS diagnosis pathways (the time from symptom onset to the point of diagnosis) are a logical place to begin this work given the varying nature of symptom onset and the importance of a quick diagnosis for optimal MS outcomes. Whereas the life course perspective provides a framework for understanding disability transitions and pathways across the life span, an intersectional feminist disability framework centers disability within an axis of overlapping social identities and locations. The combination of both frameworks provides an approach capable of examining how MS disparities and inequities emerge in different contexts over time. The chapter begins with an overview of MS and current knowledge on disparities (mainly racial) in MS prevalence, diagnosis, and outcomes. The chapter proceeds to describe the utility of key concepts of both the life course perspective and intersectional frameworks when researching health disparities. Finally, the chapter ends with a theoretical application of an intersectional feminist disability life course perspective to investigate disparities in MS diagnosis pathways.

Abstract

Purpose

The purpose of this paper is to attempt an empirical examination of government budgeting and expenditure processes in Nigeria, a developing country. It examines the current state of budgeting and public funds management (PFM) in Nigeria. It also examines the extent to which the government has used the budgetary mechanism to effectively manage the nation’s economy.

Design/methodology/approach

The paper employed simple regression estimation technique for data analysis. Time series data set of budgetary information was constructed from different archival sources over a 16-years period (2000-2015), majorly the national Appropriation Acts, press releases, regulatory and governmental reports, reports of Transparency International, World Bank and Central Intelligence Agency.

Findings

The findings confirm that the nation’s annual budgeting approach is defective and lags in achieving its fiscal objectives. The budget indicates a state of poor accountability and transparency in PFM. Findings also suggest that the level of economic development in Nigeria is not commensurate with the size of government expenditure.

Practical implications

The paper draws the attention of the government to the need to restructure its approach to budgeting and adopt a more resilient approach that suits its environment and economic peculiarities in effort to ensure efficient management and accountability of public funds. The paper also offers value to other developing countries. It provides empirical evidence that explains an aspect why the African continent remains underdeveloped hitherto.

Originality/value

This paper lends a voice to the call for a restructuring of the Nigerian budgetary system and its implementation strategy. It advocates for the adoption of an alternative budgeting approach that matches Nigeria economic realities. The paper demonstrated that the traditional budgetary approach being used by many developing countries is limited in certain ways and could hinder sustainable development.

Abstract

Purpose

The study evaluates whether an application of Ind-AS that converged with IFRS in India has enhanced financial reporting quality (FRQ) and how that is reflected in financial performance (FP).

Design/methodology/approach

Design/methodology/approach: The study uses discretionary accruals (DACC) to measure FRQ. In addition, it uses ordinary least square (OLS) regression to examine the association between Corporate Governance attributes, FRQ, and financial performance for a sample of 24 textile companies from 2010 to 2021.

Findings

The results indicate that adopting IFRS has a role in monitoring CG attributes to enhance FRQ; this means the financial reporting qualit improves somewhat with some CG attributes under Ind-AS. In addition, the results demonstrate that financial reporting quality positively influences FP.

Practical implications

There are significant effects on authorities and decision-makers. The findings from this research can benefit lawmakers by providing Ind-AS policy enforcement with more consideration. The results are also helpful for policymakers who want to improve CG and need proof of the significance of high FRQ in this respect.

Originality/value

Given the dearth of research on FRQ in India, the study extends prior literature on FRQ by examining the quality of financial reporting according to the transformation to IFRS in Indian textile firms. The theoretical contribution of the current study is the testing of agency theory towards practices of corporate governance mechanisms on FRQ and FP in the context of the textile sector.

Abstract

This paper examined briefly the background to food taboos and food habits. These food taboos and habits have great impact on the health of the Nigerian community. Sometimes, the taboos continue even among the educated members of the society. Most of the foods tabooed in Nigeria work against the least privileged and immunocompromised, i.e. women, pregnant women, children and the elderly. These groups of people are deprived of sometimes the cheapest source of protein. This paper had collected some of these taboos and where possible the reason(s) why the foods are avoided. For some of the foods, the area where the avoidance is rampant is indicated. The list will help agencies and individuals effectively fight these food taboos. Possible solutions were also suggested. Taking or consuming these foods will improve the nutritional status of Nigerians.

Abstract

Purpose

One of the mechanisms to make better bank management rests on improved corporate governance practices with diverse backgrounds including foreign representation. However, bank performance remains poor. The purpose of this study is to investigate whether foreign directors have moderating effects on the influence of board characteristics on the performance of banks in the Nigerian context.

Design/methodology/approach

The quantitative explanatory design of this study was based on a cross-sectional survey of respondents (executive and non-executive directors including independent directors) of the population of 285 bank directors in 26 Nigerian banks.

Findings

Using a sample of 121 respondents, the structural equation modelling results reveal that foreign nationality had a positive moderating effect on the influence of each board independence and audit committee on banks’ performance. However, foreign nationality negatively moderated the effect of board size and nomination committees on banks’ performance. In addition, foreign directors’ membership on boards positively moderates the relationship between remuneration committees and banks’ performance.

Research limitations/implications

The findings of this study extend our understanding of the strategic composition of the board in Nigerian banks. The findings are useful in encouraging business corporations to further strengthen their corporate governance practices. Also, foreign board members’ effectiveness is case-sensitive and committee-dependent.

Originality/value

Banks desirous of having foreign directors need to ensure that, they have the necessary capacity and fit into the local environment as well as engage foreign directors in tailored integration programmes.

Abstract

Wisdom from Africa comes in different forms: proverbs, adages, folktales with moral lessons, the use of figurative speech which transmit deep messages, a variety of wise sayings, songs, etc. Such wisdom guided many interactions including those relating to trade, entrepreneurship and other activities that drive the dynamics of economies. African communities are well known for a sense of communal living and a concern for others often manifested as solidarity. Aggregating the combined data from the preceding chapters, this final chapter in Volume 2 of Responsible Management in Africa explores the role of these two realities that are part of the African cultural heritage in promoting solidarity and inclusion. Four themes emerge: values-based education, mutual trust, personal social responsibility and sustainability factors. Beyond these four, since responsible businesses ought to have inclusive growth among their goal, they can also apply the knowledge of traditional values such as Ubuntu and Omoluabi for tackling challenges to sustainable development and contributing to attaining an ethical economy.
