Developing countries are now fully aware of the importance of the manufacturing sector as a key factor of growth and transformation of their economy. Improved technology and method of manufacturing have produced quality products at reduced cost and this has advanced development. The study uses experimental methods based on orthogonal cutting process to measure the cutting forces using a dynamometer while machining the test specimen with a diamond cutting tool at 5° rake angle. The machining forces for the dry cutting are higher than the wet cutting in the range of 31.2‐44.31, 32.09‐40.67, 29.10‐35.62, 29.21‐45.03 and 29.94‐38.74 percent for “as received”, normalized, tempered, annealed and hardened specimen, respectively. For annealed and hardened test specimen, the cutting speed of 245 rpm is ideal for machining when it gives a fine surface finish. Also for precision machining, dry turning is by far a better cost saver and cleaner option than wet turning. This is because though wet machining is relatively more expensive, it is hazardous to health. Normalized and annealed specimens require lower cutting forces and chip formation is slow. Tempering and annealing medium carbon steel facilitated rapid machining and chip formation is rapid. It is therefore an advantage to temper or anneal medium carbon steel before processing into component parts in the manufacturing industry as it saves cost and gives fine component surface finish. The paper aims to address these issues.

Tensile samples are prepared from medium carbon steel. These prepared samples were later subjected to heat‐treatment operations (normalizing, hardening, tempering and annealing). Tensile test were carried out to obtain the materials' sensitive properties used in the modeling equations. An experimental method based on orthogonal cutting is adopted to measure the machining forces using techquipment dynamometer.

It is observed that as t_u increases, F_c increases for all conditions, i.e. as t_u increases, tool‐chip contact area increases and increasing frictional force, also volume of metal removal increase resulting in increasing energy input. F_c values is highest for the normalized followed by that of the annealed. They are less for hardened and tempered. This is because of the mode of chip formation whereby ductile structures give continuous chips as against discontinuous structure for the hardened and quenched structures. Input energy is high for the former and low for the later. This is confirmed by the m values and observed chips.

There is no limitation, except for the instrumentation. On availability of the appropriate equipment, like the Kystler dynamometer for the correct reading of the experimental results.

The implication is limited to the workshop hazard during the experiment.

This study investigated the influence of social media on marital stability of married adults in Ilorin metropolis. Descriptive survey design was adopted for the study. Influence of Social Media on Marital Stability Questionnaire was used to obtain relevant information for this study. The instrument was validated and the test re-test method was employed to determine the reliability and it yielded a coefficient of 0.81. Multistage sampling procedure was used in selecting 200 respondents for the study. One research question was raised while four null hypotheses were postulated and tested at 0.05 level of significance. Percentage and weighted means were used to analyze the descriptive analysis while t-test and Analysis of Variance were used to test the postulated hypotheses at 0.05 level of significance. The findings of the study revealed that social media influenced marital stability of married adults by causing marital distraction, negligence of marital roles and responsibilities, creating conflict among spouses, encouraging marital infidelity among others. There was no significant difference in the influence of social media on marital stability of married adults in Ilorin metropolis based on gender while there were significant differences in the influence of social media on marital stability of married adults in Ilorin metropolis based on length of years in marriage, age and highest educational attainment. It was therefore recommended that married people should reduce their exposure to social media but rather be more committed to their marital relationship.

Micro, small and medium-sized enterprises are the live wire of construction industry in developing countries. These classes of establishments are most affected by economic contraction and turmoil, thus affecting their performance and survivability. Hence, the purpose of this study is to investigate and prioritize the survival determinants of construction consulting organization during economic contraction in Nigeria using quantity surveying firms as a focal point.

The study adopted the descriptive-survey design and quantitative data were collected through questionnaire purposely administered to quantity surveying firms in the Southwestern part of Nigeria. The data obtained from 99 quantity surveying firms on survival determinants were analysed using various statistical analysis such as mean score, standard deviation, Mann–Whitney U test, Kruskal–Wallis H test, and so on. Principal component analysis was used to identify the principal components of survival determinants, while the factors were prioritized using fuzzy synthetic evaluation (FSE).

The result of the analysis reveals eight factors that significantly determines the survival of firms during the period of economic contraction. Furthermore, the eight grouped factors were prioritized accordingly namely firm's innovation and diversification, ownership structure and networking, education level and management skills, and so on.

This study investigated the survival determinants of quantity surveying firms and prioritized it with the opinions of principal partners in quantity surveying establishments. As against obtaining large survey responses from all quantity surveyors in the study area that may not have practical experience of managing firms, the limited responses received provide valid basis to broaden the horizon of professionals and other stakeholders on the key determinants for firms to survive economic turmoil.

This study contributes to the body of knowledge by providing information on prioritized factors that must be considered in an appropriate order by quantity surveying firms to survive economic contraction.

Family, like other social institutions within society, has undergone changes that have impacted its structure, form, and dynamics over the years. This chapter, through an in-depth review of family and relationship literature, investigates the complexities, dynamics, and changes in the Nigerian family structure. These changes are argued to be influenced among other things by various cultural, social, political, and economic factors that have shaped the twenty-first century. As such, the contemporary Nigerian family structure has witnessed transformations such as an increase in single parenting, separation, divorce, baby-daddy and baby-mama arrangements, and the salient practice of homo-sexual relationships, among others. These changes have not only impacted family structures and formations but also have attendant consequences on relationship patterns in marriages, intimate relationships, and children’s socialization.

Business models are constantly innovating to adopt international trends. Business models are shifting toward sustainable practices to meet expectations and standards and keep on with the rest of the competitors in their industries. Recently, sustainability took a greater emphasis, and this chapter seeks to describe the main sustainability initiatives generated in international markets. Through a qualitative study made of secondary sources, strategies aligned to different sustainability initiatives are shown. Interestingly, adopting technology, digital transformation, and blockchain can enhance sustainable development.

The purpose of this paper is to describe the Eye movement desensitisation and reprocessing (EMDR) treatment of an adult female patient detained within a high secure hospital with complex mental health difficulties, including complex trauma, factitious disorder, self-injury and a history of offending. The EMDR treatment addressed the patient’s urges to engage in severe and sometimes life-threatening self-injury, a primary motive of which was to access physical healthcare interventions within a general hospital. The paper describes the wide-ranging benefits of the treatment and incorporates feedback from the patient and clinicians within her multi-disciplinary team (MDT).

Four triggers for self-injury were processed during the therapy using the DeTUR Protocol (Popky, 2005, 2009) and the Constant Installation of Present Orientation and Safety (CIPOS, Knipe, 2009a) method. In total, 18 one hour therapy sessions were delivered plus three follow-up sessions to continue to offer support and complete the post-treatment evaluation.

The level of urge for each trigger was reduced to 0 which the patient defined as “no urge to self-injure”. Benefits went well beyond self-injury with reported positive impacts on mood, thinking, sleep, concentration, memory and experience of flashbacks.

This case report demonstrates that the EMDR DeTUR Protocol together with the CIPOS method can be extremely valuable in the treatment of patients who self-injure.

The case report offers an important contribution to an area that requires much further research.

In the quest for better construction workforce management, this chapter explored the background of workforce management and related theories, models, and practices. Through a review, the chapter provided meaning to the concept of construction and workforce management. The chapter concluded that while the construction industry worldwide is important to the economic growth of the countries where it operates, the industry’s management of its workforce is challenged by several problems. These problems include the nature of the industry, skill shortage, unhealthy working environment, and poor image of the industry, among others. Also, while the construction industry is rich in diversity, this has been a major source of problems for workforce management. The chapter further revealed that to improve workforce management and attain better-performing construction organisations, careful recruitment, effective training, providing a safe working environment, putting policies to promote diversity, and ensuring innovativeness, among others, are essential.

This chapter explores “politic talks” (also known as political information) on the websites of academic libraries in land-grant state universities of the South in the context of a global retreat of democracy that emerged during former President Trump’s regime as the 45th President of the United States. The exploratory qualitative evaluation applies website content analysis of seven information offerings in three categories that include: (1) information sources (collections, resources), information policy and planning (assigned role, strategic representation), and connections (internal, external, news and events). Promising practices and illustrative examples of “politic talks” representation on academic library websites show how they are serving as significant providers of political information during current politically turbulent times. The discussion of these findings in relation to each state’s voting likelihood based on trends since 2000 has significant political implications in enhancing the role of academic libraries moving forward.

The family, as the most basic social institution, serves as the bedrock of any society. Family structures worldwide have undergone various changes in their forms, nature, and functioning, including Abia state, Nigeria. The Nigeria Civil war is one of the symbolic events attributable to changes in the Abia family structure. Changes in the family structure could influence conjugal relationships. The study explored the dynamism and changes in the family structure and conjugal relationships at different eras of the family life cycle in Abia society. A qualitative research method was used in this study. Twenty-two participants (4 life history and 18 in-depth interview participants) were recruited in this study with purposive sampling techniques. Using an archival checklist, life histories, and an in-depth guide, information was elicited on family structure and conjugal relationships. The study was subjected to thematic analysis. The findings revealed dynamism and changes in family structure, with polygyny being most prevalent prior to the civil war, the emergence of step-parent and single-parent families during the civil war, and monogamy being most prevalent, with increasing single-parent and step-parent families contemporaneously. The conjugal relationship shifted from having concubines (acceptable and practised covertly) to having side chicks (been practised covertly). The Nigerian civil war had an impact on the observed dynamics in family structure during the civil war and immediate post-civil war. Other factors such as religion, education, civilization, and migration, among others, influenced the contemporary Abia family structure. Understanding family structure dynamics could be useful in solving issues regarding family and conjugal trajectories.
