Explaining the emergence of hedonic motivations in enterprise social networks and their impact on sustainable user engagement
Authors: Meske Christian , Junglas Iris , Stieglitz Stefan 
Published: May 2019

Purpose
Enterprise social networks (ESNs) in organizations have become an increasingly important technology to support the exchange of information and knowledge. Many ESN projects fail due to insufficient engagement in the long run, leading to the high risk of sunk costs. The purpose of this paper is to investigate how hedonic motivations, along with normative motivations, play an important role in determining an employee’s intention to continuously participate in ESN. Based on the Four-Drive Model and hence borrowing from behavioral economics, it is investigated how such hedonic motivations emerge in organizational ESNs.

Design/methodology/approach
This study is set within the context of a global enterprise of the logistics and courier industry. The authors first derived hypotheses from the Four-Drive Model to build the research model on the emergence of hedonic motivation. Then, the authors derived hypotheses from existing adoption literature regarding the impact of hedonic motivations and normative motivations on ESN use continuance. Following, a quantitative survey was conducted to test these hypotheses. In the study, structural equation modeling is applied, based on partial least squares.

Findings
The results show that the extent to which an ESN supports the drives to comprehend, acquire, bond and defend starkly influences an employee’s hedonic motivations. In addition, it is shown that hedonic motivations have a much stronger influence on use continuance than normative motivations.

Originality/value
Research on hedonic motivations in the work context is still underrepresented, in management science as well as information systems (IS) research. Hence, theoretical approaches to explain and predict the emergence of hedonic motivations in IS usage are missing. With the study, the authors will close this theoretical gap. The study contributes to IS research not only by evaluating the role of hedonic motivation for ESN usage, but also by providing an approach to explain key drivers behind it. To the best of the authors’ knowledge, this is the first study to empirically test the Four-Drive Model in a voluntary IS context, adding valuable knowledge about human behaviors in digital work environments.

Published: May 2019

PurposeIn view of dynamic and widespread economic transformation in emerging economies, managing organizational change and growth in this context deserves more research attention. The purpose of this paper is to examine how three organizations in different industries manage change, growth and transformation in their organizational ecosystem.Design/methodology/approachThe authors conducted in-depth interviews with the leadership of three organizations in different economic sectors in India, a country representing an emerging economy. The authors also reviewed historical data from these organizations. Three case studies illustrating the evolution of these organizations were developed from the data collected.FindingsLessons and implications from the three case studies suggest the following key elements of effective organizational change mechanisms in an emerging economy: visionary entrepreneurial leadership; program quality excellence; scale growth and scope expansion; network capabilities; and sustainable stakeholders’ engagement. At the same time, this study also shows how these organizations manage change, growth and transformation in the context of a society with strong traditions and cultural norms.Research limitations/implicationsResults and conclusions may be limited by the fact that the study is based on three case studies. Additional studies from a variety of industries with large numbers of participants will be helpful in more fully understanding the ways in which change, growth and transformation can best be developed and deployed in different organizational settings.Practical implicationsThe proposed model of organizational change in an emerging economy may assist organizational leadership in designing and sustaining their change efforts.Social implicationsThis study highlights the role of visionary entrepreneurial leadership and the impact of organizational growth mechanisms on organizational value delivery capabilities and organizational reputation.Originality/valueLessons and implications of five growth steps of outstanding organizations in an emerging economy context provide valuable insight for organizational change, growth and transformation in other emerging contexts.

First, the population was divided into two strata. Second, universities were selected on a random basis and finally, respondents were selected on simple random basis.FindingsThe study used structural equation modeling and hierarchical regression techniques to test the hypotheses. The study found that in the presence of high SE and low resistance to change learning culture more likely to influence on MTT.Research limitations/implicationsThe study contributed to cognitive theory, signaling theory and experimental learning theory and has implications for managers and academic policymakers.Originality/valueThe study is a novel attempt to examine the side by side role of learning culture, SE and learning transfer climate toward MTT.
The financial intelligence unit and money laundering control in Tanzania
Authors: Mniwasa Eugene E. 
Published: May 2019

Purpose
This paper aims to explore the role of the financial intelligence unit in Tanzania in fighting against money laundering and its predicate offences, examine its potential in controlling the problem and describe factors that undermine its efficacy.

Design/methodology/approach
The doctrinal research approach is used to analyse Tanzania’s anti-money laundering law and appraise its effectiveness in facilitating operations of the financial intelligence unit in fighting against money laundering and its predicate offences. The law-in-context approach is applied to interrogate the anti-money laundering law and describe non-law factors that impinge on the efficiency of Tanzania’s financial intelligence unit.

Findings
The law vests the financial intelligence unit with powers to perform a number of functions that are significant in fighting against money laundering and its predicate offences in Tanzania. The unit has been instrumental in curbing money laundering. The efficacy of this anti-money laundering agency, which is at its infancy stage, is emasculated by law-related, institutional and non-law factors. These factors undercut the potency of the agency.

Practical implications
There is a need for Tanzania to undertake policy, legislative and institutional reforms to augment the efficacy of the financial intelligence unit. The reforms should be implemented concurrently with other measures, which will enhance the country’s anti-money money laundering regime.

Originality/value
This paper applies the legal and non-law perspectives to evaluate the effectiveness of the financial intelligence unit as an essential component of Tanzania’s anti-money laundering regime. It proposes law-related and non-law approaches to augment the efficiency of the unit and the country’s anti-money laundering regime in general.
Tracing, freezing and confiscating the proceeds of crime in Cyprus
Authors: Pavlidis George , Satolias Konstantinos 
Published: May 2019

Purpose
As a dynamic business and financial centre, the Republic of Cyprus is called upon to protect its economy and society from money laundering and criminal infiltration. To address these risks, the Republic of Cyprus has developed a comprehensive legal framework in compliance with the relevant international and EU standards. The purpose of this paper is to critically examine the legislative tools for tracing, freezing and confiscating the proceeds of crime in the Republic of Cyprus with special reference to their strengths, weaknesses and compatibility with the relevant international and EU norms.

Design/methodology/approach
This paper draws on legal scholarship, jurisprudence, reports and other open source data to analyse important legislative developments in Cyprus in the fields of tracing, freezing and confiscating the proceeds of crime.

Findings
The legislative developments that will be examined are Law 188(I)/2007, and its recent amendments which effectively target the proceeds of crime in Cyprus. Despite some weaknesses, the legislative provisions in Cyprus are compatible with international and EU norms on tracing, freezing and confiscation, while they promote international and EU cooperation in these domains.

Originality/value
Since the amendments of Law 188(I)/2007 came into force, this has been, to the best of the authors’ knowledge, the first comprehensive study examining the strengths and weaknesses of the legislative framework on asset tracing, freezing and confiscation, as well as its compatibility with international and EU standards.
European antiquities trade: a refuge for money laundering and terrorism financing
Authors: Teichmann Fabian Maximilian Johannes 
Published: May 2019

PurposeThis paper aims to demonstrate how criminals launder money in the antiquities trade in Austria, Germany, Liechtenstein and Switzerland.Design/methodology/approachA qualitative content analysis of 58 semi-structured expert interviews with both criminals and prevention experts and a quantitative survey of 184 compliance officers revealed the concrete techniques used to launder money in the European antiquities trade.FindingsThe antiquities market facilitates the placement, layering and integration of the transfer of assets to terrorist organizations. Most importantly, it is among the few profitable methods of laundering money.Research limitations/implicationsAs the findings of the qualitative study are based on semi-standardized interviews, they are limited to the 58 interviewees’ perspectives.Practical implicationsThe identification of concrete methods of money laundering and terrorism financing aims to provide compliance officers, law enforcement agencies and legislators with valuable insight into criminal activity.Originality/valueWhile the existing literature focuses on organizations fighting money laundering and the financing of terrorism, this study instead describes how criminals avoid detection by taking into account prevention and criminal perspectives.
The viability of international anti-criminal finance frameworks
Authors: Fazlur Rahman Nurhannani 
Published: May 2019

Purpose
The purpose of this paper is to draw attention to the effect of the growing informal financial sector (IFS) on the effectiveness of anti-criminal finance laws. Specifically, the growth of the IFS has been brought on by the unprecedented rise in refugee and migrant movement around the world. This paper will focus on how refugee smuggling in the Eastern Mediterranean and Western Balkan region – and the consequent rise of the IFS – has affected the suitability of apply anti-money laundering and financial action task force frameworks in these countries.

Design/methodology/approach
It assesses the effectiveness of national and international legal documents on anti-criminal finance. It also uses data sets and analyses secondary and primary sources to estimate the size and importance of the IFS.

Findings
The exponential and rapid growth of the IFS has undermined efforts to prevent the financing of trafficking, terrorism, corruption and money-laundering. The present legal devices to address criminal finance has been wholly inadequate and counter-productive.

Research limitations/implications
There are limited reliable or accurate data available on the IFS, how much money goes through it or how important it is to criminal activities such as money laundering or terrorist finance. Without field-research, this study remains exploratory.

Practical implications
The growth of the IFS and migratory movement is a complex dilemma that must be accounted for when seeking to truly improve anti-criminal finance laws, especially in developing and transition countries.

Originality/value
This paper demonstrates the importance of considering the IFS and migratory and refugee movements in creating legal instruments to combat financial crime. It also suggests a direction for future research.
Defining the antecedents of experience co-creation as applied to alternative consumption models
Authors: Schallehn Holger , Seuring Stefan , Strähle Jochen , Freise Matthias 
Published: May 2019

PurposeThe purpose of this paper is to propose a conceptual framework of experience co-creation that captures the multi-dimensionality of this construct, as well as a research process for defining of the antecedents of experience co-creation.Design/methodology/approachThe framework of experience co-creation was conceptualized by means of a literature review. Subsequently, this framework was used as the conceptual basis for a qualitative content analysis of 66 empirical papers investigating alternative consumption models (ACMs), such as renting, remanufacturing, and second-hand models.FindingsThe qualitative content analysis resulted in 12 categories related to the consumer and 9 related to the ACM offerings that represent the antecedents of experience co-creation. These categories provide evidence that, to a large extent, the developed conceptual framework allows one to capture the multi-dimensionality of the experience co-creation construct.Research limitations/implicationsThis study underscores the understanding of experience co-creation as a function of the characteristics of the offering – which are, in turn, a function of the consumers’ motives as determined by their lifeworlds – as well as to service design as an iterative approach to finding, creating and refining service offerings.Practical implicationsThe investigation of the antecedents of experience co-creation can enable service providers to determine significant consumer market conditions for forecasting the suitability and viability of their offerings and to adjust their service designs accordingly.Originality/valueThis paper provides a step toward the operationalization of the dimension-related experience co-creation construct and presents an approach to defining the antecedents of experience co-creation by considering different research perspectives that can enhance service design research.
On Christoffel roots for nondetached slowness surfaces
Authors: Bos Len , Slawinski Michael A. , Stanoev Theodore 
Published: May 2019

ABSTRACTThe only restriction on the values of the elasticity parameters is the stability condition. Within this condition, we examine the Christoffel equation for nondetached qP slowness surfaces in transversely isotropic media. If the qP slowness surface is detached, each root of the solubility condition corresponds to a distinct smooth wavefront. If the qP slowness surface is nondetached, the roots are elliptical but do not correspond to distinct wavefronts; also, the qP and qSV slowness surfaces are not smooth.
Linking size spectrum, energy flux and trophic multifunctionality in soil food webs of tropical land‐use systems
Authors: Potapov Anton M. , Klarner Bernhard , Sandmann Dorothee , Widyastuti Rahayu , Scheu Stefan 
Published: May 2019

AbstractMany ecosystem functions depend on the structure of food webs, which heavily relies on the body size spectrum of the community. Despite that, little is known on how the size spectrum of soil animals responds to agricultural practices in tropical land‐use systems and how these responses affect ecosystem functioning.We studied land‐use‐induced changes in below‐ground communities in tropical lowland ecosystems in Sumatra (Jambi province, Indonesia), a hot spot of tropical rainforest conversion into rubber and oil palm plantations. The study included ca. 30,000 measured individuals from 33 high‐order taxa of meso‐ and macrofauna spanning eight orders of magnitude in body mass. Using individual body masses, we calculated the metabolism of trophic guilds and used food web models to calculate energy fluxes and infer ecosystem functions, such as decomposition, herbivory, primary and intraguild predation.Land‐use change was associated with reduced abundance and taxonomic diversity of soil invertebrates, but strong increase in total biomass and moderate changes in total energy flux. These changes were due to increased biomass of large‐sized decomposers in soil, in particular earthworms, with their share in community metabolism increasing from 11% in rainforest to 59%–76% in jungle rubber, and rubber and oil palm plantations. Decomposition, that is the energy flux to decomposers, stayed unchanged, but herbivory, primary and intraguild predation decreased by an order of magnitude in plantation systems. Intraguild predation was very important, being responsible for 38% of the energy flux in rainforest according to our model.Conversion of rainforest into monoculture plantations is associated by an uneven loss of size classes and trophic levels of soil invertebrates resulting in sequestration of energy in large‐sized primary consumers and restricted flux of energy to higher trophic levels. Pronounced differences between rainforest and jungle rubber reflect sensitivity of rainforest soil animal communities to moderate land‐use changes. Soil communities in plantation systems sustained high total energy flux despite reduced biodiversity. The high energy flux into large decomposers but low energy fluxes into other trophic guilds suggests that trophic multifunctionality of below‐ground communities is compromised in plantation systems.

Abstract

Understanding the functional relationship between marine predators and their prey is vital to inform ecosystem‐based management. However, collecting concurrent data on predator behaviour and their prey at relevant scales is challenging. Moreover, opportunities to study these relationships in the absence of industrial fishing are extremely rare.

We took advantage of an experimental fisheries closure to study how local prey abundance influences foraging success and chick condition of Endangered African penguins Spheniscus demersus in the Benguela ecosystem.

We tracked 75 chick‐provisioning penguins with GPS–time–depth devices, measured body condition of 569 chicks, quantified the diet of 83 breeding penguins and conducted 12 forage fish hydro‐acoustic surveys within a 20 km radius of Robben Island, South Africa, over three years (2011–2013). Commercial fishing for the penguins' main prey, sardine Sardinops sagax and anchovy Engraulis encrasicolus, was prohibited within this 20 km radius during the study period.

Local forage fish abundance explained 60% of the variation in time spent diving for 14 penguins at sea within 2 days of a hydro‐acoustic survey. Penguin foraging effort (time spent diving, number of wiggles per trip, number of foraging dives and the maximum distance travelled) increased and offspring body condition decreased as forage fish abundance declined. In addition, quantile regression revealed that variation in foraging effort increased as prey abundance around the colony declined.

Policy implications. Our results demonstrate that local forage fish abundance influences seabird foraging and offspring fitness. They also highlight the potential for offspring condition and the mean–variance relationship in foraging behaviour to act as leading indicators of poor prey abundance. By rapidly indicating periods where forage resources are scarce, these metrics could help limit seabird fisheries competition and aid the implementation of dynamic ocean management.
Carbon use efficiency of mycorrhizal fungal mycelium increases during the growing season but decreases with forest age across a Pinus sylvestris chronosequence

Abstract

In boreal forest soils, mycelium of mycorrhizal fungi is pivotal for regulating soil carbon (C) cycling and storage. The carbon use efficiency (CUE), a key parameter in C cycling models, can inform on the partitioning of C between microbial biomass, and potential soil storage, and respiration. Here, we test the dependency of mycorrhizal mycelial CUE on stand age and seasonality in managed boreal forest stands.

Based on mycelial production and respiration estimates, derived from sequentially incubated ingrowth mesh bags, we estimated CUE on an ecosystem scale during a seasonal cycle and across a chronosequence of eight, 12‐ to 158‐year‐old, managed Pinus sylvestris forest stands characterized by decreasing pH and nitrogen (N) availability with increasing age. Mycelial respiration was related to total soil respiration, and by using eddy covariance flux measurements, primary production (GPP) was estimated in the 12‐ and 100‐year‐old forests, and related to mycelial respiration and CUE.

As hypothesized, mycelial CUE decreased significantly with increasing forest age by c. 65%, supposedly related to a shift in mycorrhizal community composition and a metabolic adjustment reducing their own biomass N demand with declining soil N availability. Furthermore, mycelial CUE increased by a factor of five over the growing season; from 0.03 in May to 0.15 in November, and we propose that the seasonal change in CUE is regulated by a decrease in photosynthate production and temperature. The respiratory contribution of mycorrhizal mycelium ranged from 14% to 26% of total soil respiration, and was on average 17% across all sites and occasions.

Synthesis. Carbon is retained more efficiently in mycorrhizal mycelium late in the growing season, when fungi have access to a more balanced C and nutrient supplies. Earlier in the growing season, at maximum host plant photosynthesis, when below‐ground C availability is high in relation to N, the fungi respire excess C resulting in lower mycelial carbon use efficiency (CUE). Additionally, C is retained less efficiently in mycorrhizal fungal biomass in older forest stands characterized by more nutrient depleted soils than younger forest stands.
Chinese economy in the new era
Authors: Lau Lawrence J. 
Published: May 2019

AbstractThe “new era”, a term introduced by President Xi Jinping, may also be identified as the Xi era, during which China will be transformed from a moderately well‐off to a strong and wealthy nation. In the new era, the Chinese Government will deepen economic reform, widen economic opening and enhance the quality of economic growth. / Our projections show that by 2020, Chinese real GDP per capita, in 2017 prices, will exceed US$10,000, an economic development milestone. By 2031, Chinese real GDP will surpass US real GDP (US$29.4 trillion vs US$29.3 trillion), making China the largest economy in the world. However, Chinese real GDP per capita will still lag behind the US significantly, amounting to only one‐quarter of that of the United States. By 2050, Chinese real GDP will reach US$82.6 trillion, compared to US$51.4 trillion for the United States. However, in terms of real GDP per capita, China will still lag significantly behind, at US$53,000, slightly less than the current level of US real GDP per capita, compared to US$134,000 for the United States.
