Design/Methodology/Approach – Data collection on mangroves was retrieved using a Quadrat Sampling Method, the acquisition of information about the status of conservation of mangrove ecosystems was done using the interview method.

Findings – The results showed that there are four types of mangroves, and mangrove ecosystem conservation efforts have not been made by the people of Leupung. The conclusions of this study are as follows: the types of mangroves found in the area of Krueng Reuleng River are Nypa fruticans, Sonneratia alba, Acrostichum aureum, and Thespesia populnea. Conservation measures have not been undertaken to preserve the mangrove ecosystem in the area of Krueng Reuleng River.

Research Limitations/Implications – The location can be used as a site of practical research on the type of mangroves in the Krueng Reuleng River area for students studying biology.

Originality/Value – In addition to upgrading the data on the types of mangroves, this paper could be a reference for any relevant field.

Purpose – The purpose of this research is to investigate the relationship of lead (Pb) and zinc (Zn) contents in sediment of Faunus ater (F. ater) population density and to analyze the relationship between Pb and Zn accumulation in F. ater with F. ater density in Reuleng River, Leupung, Aceh Besar.

Design/Methodology/Approach – Sampling was conducted in November 2016 until January 2017. Density of F. ater was analyzed by density formula while its relationship to Pb and Zn in sediments and F. ater was conducted by correlation analysis method.

Findings – The results showed that correlation between Pb and Zn in sediments and in F. ater varies at each locations on every month of sampling. Pb and Zn content in sediments found a fluctuating relationship in each month of sampling with density of F. ater. Correlation of Pb content in sediments with F. ater density showed a medium correlation in January 2017 with r-value = 0.665. Zn in sediment has a very strong correlation to F. ater density in November 2016 with r-value = 0.891. Pb in F. ater has a medium correlation to F. ater density in January 2017 with r-value = 0.436. Furthermore, accumulation of Zn in F. ater to its density does show some apparent correlation in each month of sampling.

Research Limitation/Implications – This research gives information about the relationship of Pb and Zn contents in sediment to density of F. ater and to analyze correlation of Pb and Zn in F. ater to density of F. ater in Reuleng River, Leupung, Aceh Besar district.

Originality/Value – This is the first time research is conducted about on the correlation between lead and zinc to obtain the density of F. ater.

Purpose – The purpose of this research is to examine the diversity of macrozoobenthos as well as its relationship with water quality and substrate in the pond culture area.

Design/Methodology/Approach – The method of sampling area is on five observation stations by purposive sampling. The research was done indirectly (ex situ) for macrozoobenthic identification at the Ecology Laboratory, Faculty of Mathematics and Natural Sciences.

Findings – The fairness/uniformity index obtained from the five research stations ranging from 0.483 to 0.923 indicates a high degree of uniformity. This indicates that the macrozoobenthos biological index at the study site can be used as an indicator that water quality is in good condition and has the potential to be developed into an aquaculture area as well as supporting the success of the shrimp farming as one of the sub-systems of the shrimp agribusiness.

Research Limitations/Implications – This research can be a source of information for the management and utilization of environment in the research area, so that shrimp harvest can be optimized in the pond farming area.

Originality/Value – This research has found that macrozoobenthos included 61 species.

Purpose – This paper aims to detect or identify the presence of hydrocarbon infiltration on sampling point in the Rambe River area according to the obtained VOCs and the adsorbed SVOCs.

Design/Methodology/Approach – The Gore-sorber method has been used to capture volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) as indicators of subsurface hydrocarbon generation and entrapment. This method is usually used in environmental surveys for the oil investigations in certain areas for surface survey screening, designed to collect a broad range of VOCs and (SVOCs) at lower concentrations, quickly and inexpensively. The results also indicated a general correlation between the GORE-SORBER and reference method data. The research was conducted in Rambe River Village, Tebing Tinggi sub-district of Tanjung Jabung Barat district, Jambi Province Indonesia. The collection of the Gore-Sorber modules were analyzed using a gas chromatography-mass spectrometer thermal desorption (GC/MS).

Findings – The results showed that from all sampling points in Tebing Tinggi areas, the dominant components detected are carbonyl sulphide, dimethyl sulfide, ethane, propane, butane, 2-methyl butane, pentane, and carbon sulfide with carbon chain in the range C2-C5. These hydrocarbon gases (C1-C4) which may be from thermogenic or microbial processes. The highest concentrations of carbonyl sulfide were 392.67 ng and dimethyl disulfide 261.90 ng.

Originality/Value – In addition to estimate and predict the petroleum formation, this article provides information about the presence of oil fields in the area of the Sungai Rambe Village

The notion of deeper experiences of Hindu devotees inspired by divine images and sacred places has roots in the historical past, going back to the Vedic period (ca. 2500 BCE), where we find rich literature on performances, rituals and merits of pilgrimages. Considered the bridge between human beings and divinities, the experiences received are the resultant ‘blissful fruit’ (phala) that helps the spiritual healing of pilgrims through awakening conscience and understanding the manifested meanings, symbolism, purposes and gains. This system can be viewed concerning the ‘texts’ (the mythology, ancient text and related narratives) and the ‘context’ (contemporality and living tradition). These rules and performances have regional perspectives of distinctions, but they also carry the sense of universality, i.e. locality (sthānic) and universality (sarvavyāpika) interfaces. The devout Hindus reflect their experiences in conception, perception, reception and co-sharedness – altogether making the wholistic network of belief systems, i.e. the religious wholes in Hindu society. This chapter deals with four aspects: the historical and cultural contexts, the meanings and merits received, the motives and the journey and interfacing experiences. The study is based on the experiential and questionnaire-based exposition and interviews of pilgrims at nine holy places during 2015–2019 on various festive occasions and is illustrated with ancient texts and treatises. The sacred cities included are Prayagraj, Varanasi, Gaya, Ayodhya, Vindhyachal, Ganga Sagar, Chitrakut, Mathura Vrindavana and Bodh Gaya.

For a number of years, the construction industry has seen an ongoing shift from design-bid-build to design-build contracts. This transition in contract type entails changes for both the organizations and the individuals involved. Consequently, the purpose of this paper is to investigate how the client manages the transition between the different contract types from an organizational change perspective in a project-led organization.

A multiple case study of six infrastructure projects with DB contracts, all managed by the Swedish Transport Administration, was conducted. The major source of data is semi-structured interviews with respondents from both the client and the contractors.

Results suggest that the transition has resulted in a mix of design-bid-build and design-build as contract type owing to issues when changing in a project-led organization. A change in vision also requires a concomitant change in culture, systems and roles.

The study only includes cases from the Swedish transport infrastructure sector, which limits the generalizability. The findings are also indicative owing to the small number of cases.

The findings further our understanding of managing change in complex projects, which might help practitioners to manage change in a more integrated way.

The findings enrich our understanding of the systemic change that a switch in contract types can have in inter-organizational complex projects such as transport infrastructure projects. Furthermore, it emphasizes the intricate task of change management in project-led organizations and its effects on roles and responsibilities.

A policy of surveillance which interferes with the fundamental right to a private life requires credible justification and a supportive evidence base. The authority for such interference should be clearly detailed in law, overseen by a transparent process and not left to the vagaries of administrative discretion. If a state surveils those it governs and claims the interference to be in the public interest, then the evidence base on which that claim stands and the operative conception of public interest should be subject to critical examination. Unfortunately, there is an inconsistency in the regulatory burden associated with access to confidential patient information for non-health-related surveillance purposes and access for health-related surveillance or research purposes. This inconsistency represents a systemic weakness to inform or challenge an evidence-based policy of non-health-related surveillance. This inconsistency is unjustified and undermines the qualities recognised to be necessary to maintain a trustworthy confidential public health service. Taking the withdrawn Memorandum of Understanding (MoU) between NHS Digital and the Home Office as a worked example, this chapter demonstrates how the capacity of the law to constrain the arbitrary or unwarranted exercise of power through judicial review is not sufficient to level the playing field. The authors recommend ‘levelling up’ in procedural oversight, and adopting independent mechanisms equivalent to those adopted for establishing the operative conceptions of public interest in the context of health research to non-health-related surveillance purposes.

This book chapter takes an institutional perspective on competing logics in global markets concerned with sustainability values and how market actors in the form of buyers and sellers attempt to solve these conflicting situations. We do this by identifying competing institutional logics in global market contexts aiming for sustainability values, together with techniques for navigating these competing institutional logics in the organizational field studied. As an empirical illustration, we use a case study of buyers and sellers in two different markets where sustainability has come into focus for their market relationships. This viewpoint allows us to better understand how global market actors deal with the competing institutional logics in their market context. We make three contributions with this research: firstly, we identify the institutional logics in global markets towards sustainability; secondly, we demonstrate how global market actors prioritize among the competing logics and their market relationships and thirdly, we outline what this means for the relationship between buyers and sellers in global markets towards sustainability.

This chapter argues that despite the horizontal and self-organizing character of cocreation processes, leadership is essential for initiating and facilitating collaboration and securing the production of effective SDG solutions. Leadership is defined as a two-way street between leaders who guide their followers and enable them to reach their goals and followers who provide valuable input to leaders in a bottom-up process. Five crucial leadership functions are identified and the role of power in leadership is discussed. The chapter also considers the particular strategies for leading cocreation networks and partnerships and the skills and competencies necessary for pursuing these strategies. Finally, the chapter describes the importance of building leadership capacity through the recruitment of leadership teams.
