AbstractDoggerland was a land mass occupying an area currently covered by the North Sea until marine inundation took place during the mid-Holocene, ultimately separating the British land mass from the rest of Europe. The Storegga Slide, which triggered a tsunami reflected in sediment deposits in the Northern North Sea, North East coastlines of the British Isles and across the North Atlantic, was a major event during this transgressive phase. The spatial extent of the Storegga tsunami however remains unconfirmed because to date no direct evidence for the event has been recovered from the southern North Sea. We present evidence that Storegga associated deposits occur in the southern North Sea. Palaeo-river systems have been identified using seismic survey in the southwestern North Sea and sedimentary cores extracted to track the Mid Holocene inundation. At the head of one palaeo-river system near the Outer Dowsing Deep, theSouthern River, we observed an abrupt and catastrophic inundation stratum. Based on lithostratigraphic, macro and microfossils and sedimentary ancient DNA (sedaDNA) evidence, supported by optical stimulation luminescence (OSL) and radiocarbon dating, we conclude these deposits were a result of the Storegga event. Seismic identification of this stratum to adjacent cores indicated diminished traces of the tsunami, largely removed by subsequent erosional processes. Our results demonstrate the catastrophic impact of Storegga within this area of the Southern North Sea, but indicate that these effects were temporary and likely localized and mitigated by the dense woodland and topography of the area. We conclude clear physical remnants of the wave are likely to be restricted to inland basins and incised river valley systems.
Tracking tendon fibers to their insertion – a 3D analysis of the Achilles tendon enthesis in mice
Authors: Sartori Julian , Stark Heiko 
Published: February 2020

AbstractTendon insertions to bone are heavily loaded transitions between soft and hard tissues. The fiber courses in the tendon have profound effects on the distribution of stress along and across the insertion. We tracked fibers of the Achilles tendon in mice in micro-computed tomographies and extracted virtual transversal sections. The fiber tracks and shapes were analyzed from a position in the free tendon to the insertion with regard to their mechanical consequences. The fiber number was found to stay about constant along the tendon. But the fiber cross-sectional areas decrease towards the insertion. The fibers mainly interact due to tendon twist, while branching only creates small branching clusters with low levels of divergence along the tendon. The highest fiber curvatures were found within the unmineralized entheseal fibrocartilage. The fibers inserting at a protrusion of the insertion area form a distinct portion within the tendon. Tendon twist is expected to contribute to a homogeneous distribution of stress among the fibers. According to the low cross-sectional areas and the high fiber curvatures, tensile and compressive stress are expected to peak at the insertion. These findings raise the question whether the insertion is reinforced in terms of fiber strength or by other load-bearing components besides the fibers.
Lanthanide-dependent alcohol dehydrogenases require an essential aspartate residue for metal coordination and function

Published: February 2020

ABSTRACTThe presence of lanthanide elements (Ln3+) and pyrroloquinoline quinone (PQQ) containing cofactors in XoxF methanol dehydrogenases (MDHs) and ExaF ethanol dehydrogenases (EDHs) has expanded the list of biological elements and opened novel areas of metabolism and ecology. Other MDHs known as MxaFIs are related in sequence and structure to these proteins, yet they instead possess a Ca2+-PQQ cofactor. An important missing piece of the Ln3+puzzle is defining what protein features distinguish enzymes using Ln3+-PQQ cofactors from those that do not. In this study, we investigated the functional importance of a proposed lanthanide-coordinating aspartate using XoxF1 MDH from the model methylotrophic bacteriumMethylorubrum extorquensAM1. We report two crystal structures of XoxF1, one containing PQQ and the other free of this organic molecule, both with La3+bound in the active site region and coordinated by Asp320. Using constructs to produce either recombinant XoxF1 or its D320A variant, we show Asp320 is needed forin vivocatalytic function,in vitroactivity of purified enzyme, and coordination of La3+. XoxF1 and XoxF1 D320A, when produced in the absence of La3+, coordinate Ca2+, but exhibit little or no catalytic activity. In addition, we generated the parallel substitution to produce ExaF D319S, and showed the enzyme loses the capacity for efficient ethanol oxidation with La3+. These results provide empirical evidence of an essential Ln3+-coordinating aspartate for the function of XoxF MDHs and ExaF EDHs; thus, supporting the suggestion that sequences of these enzymes, and the genes that encode them, are markers for Ln3+metabolism.

ABSTRACTBackgroundCommunity responses are important for outbreak management during the early phase when non-pharmaceutical interventions are the major preventive options. Therefore, this study aims to examine the psychological and behavioral responses of the community during the early phase of the COVID-19 epidemic in Hong Kong.MethodA cross-sectional online survey was launched within 36 hours after confirmed COVID-19 cases were first reported. Councilors of all 452 district council constituency areas were approached for survey dissemination. Respondent demographics, anxiety level, risk perception, sources to retrieve COVID-19 information, actual adoption and perceived efficacy of precautionary measures were collected.ResultAnalysis from 1715 complete responses indicated high perceived susceptibility (89%) and high perceived severity (97%). Most respondents were worried about COVID-19 (97%), and had their daily routines disrupted (slightly/greatly: 98%). The anxiety level, measured by the Hospital Anxiety and Depression Scale, was borderline abnormal (9.01). Nearly all respondents were alert to the disease progression (99.5%). The most trusted information sources were doctors (84%), followed by broadcast (57%) and newspaper (54%), but they were not common information sources (doctor: 5%; broadcast: 34%; newspaper: 40%). Only 16% respondents found official websites reliable. Enhanced personal hygiene practices and travel avoidance to China were frequently adopted (>77%) and considered effective (>90%). The adoption of social-distancing measures was lower (39%-88%), and their drivers for greater adoption include: being female (adjusted odds ratio [aOR]:1.27), living in the New Territories (aOR:1.32-1.55), perceived as having good understanding of COVID-19 (aOR:1.84) and being more anxious (aOR:1.07).DiscussionRisk perception towards COVID-19 in the community was high. Most respondents are alert to the disease progression, and adopt self-protective measures. This study contributes by examining the psycho-behavioral responses of hosts, in addition to the largely studied mechanistic aspects, during the early phase of the current COVID-19 epidemic. The timely psychological and behavioral assessment of the community is useful to inform subsequent interventions and risk communication strategies as the epidemic progresses.
Computerized content analysis of online data – opportunities for marketing scholars and practitioners
Authors: Kietzmann Jan , Pitt Leyland F. 
Published: February 2020

Purpose
The purpose of this paper is to summarize the main developments from the early days of manual content analysis to the adoption of computer-assisted content analysis and the emerging artificial intelligence (AI)-supported ways to analyze content (primarily text) in marketing and consumer research. A further aim is to outline the many opportunities these new methods offer to marketing scholars and practitioners facing new types of data.

Design/methodology/approach
This conceptual paper maps our methods used for content analysis in marketing and consumer research.

Findings
This paper concludes that many new and emerging forms of unstructured data provide a wealth of insight that is neglected by existing content analysis methods. The main findings of this paper support the fact that emerging methods of making sense of such consumer data will take us beyond text and eventually lead to the adoption of AI-supported tools for all types of content and media.

Originality/value
This paper provides a broad summary of nearly five decades of content analysis in consumer and marketing research. It concludes that, much like in the past, today’s research focuses on the producers of the words than the words themselves and urges researchers to use AI and machine learning to extract meaning and value from the oceans of text and other content generated by organizations and their customers.
Perpetrator or victim? A review of the complexities of domestic violence cases
Authors: Hamel John Marc 
Published: February 2020

PurposeThe purpose of this study is to provide a review of research on the merits of public policy and law enforcement responses to intimate partner violence (IPV) in the USA using prevalence rates and dynamics of IPV.Design/methodology/approachA reading of recent comprehensive literature reviews was supplemented by a PsychInfo search of relevant articles published in peer-reviewed journals.FindingsLaws against IPV in the USA have been enforced much more vigorously in comparison with most of the world, many of which have no such laws at all. While more perpetrators have been held accountable for their actions – increasing the safety of victims – many perpetrators are never brought to justice, and “mandatory arrest” laws sometimes result in arrests being made with a scant evidence of wrongdoing. This state of affairs can be traced two key factors. First, the persistence of the gender paradigm – an outdated and discredited set of assumptions about the role of gender in IPV – as formulated by battered women’s advocates, which has informed IPV public policy for several decades. Second, the complex nature of IPV, a phenomenon that mostly happens behind closed doors, varies widely in frequency, intensity, mutuality and impact on victims, and it cannot easily be framed in binary victim/perpetrator terms.Practical implicationsThe arrest and prosecution of possibly innocent individuals is in violation of due process and mitigates against our common efforts to reduce IPV in our communities.Originality/valueA compact summary of the relevant IPV policy literature is presented with a focus on an under-studied topic, i.e. the problems inherent in the categorization of individuals as either victims or perpetrators and the failure to recognize the inherently complex nature of IPV.
Multinational enterprises motivational factors in capitalizing emerging market opportunities and preparedness of India
Authors: Bhattacheryay Suranjan 
Published: February 2020

PurposeThe purpose of the study is to heighten intrinsic advantages, dis-advantages, being enjoyed by emerging country firms and the motivational factors that influence multinational enterprises (MNEs) to establish long-lasting relationship with emerging economies. The study also highlights the steps initiated by India by executing reform friendly foreign direct investment policy to attract foreign investments.Design/methodology/approachThe study is descriptive in nature, based on secondary data, sourced from various reports of India Government and the Central Bank of India.FindingsThe Indian economy has undergone profound and substantial liberalization and made sweeping reforms in most of its sectors besides adopting internationalization policy agendas to upkeep their domestic firms in “going global”. However, India needs to amend the existing restrictive labour and land laws besides providing efficient employable workforce. India further needs a less cash economy, which ultimately marches into digitized credit system to build India as one of the best attractive countries in the eyes of global investors.Research limitations/implicationsAs the study is based on secondary data, it may be general, in explicit and may not be perfect in concluding decision.Social implicationsMNEs play a major force in driving globalization of the world economy. However, MNEs face a variety of complex and multiple challenges in establishing strategic control over emerging economies. In spite of all odds, MNEs generate and capture value to host country firms by applying unique business models besides combining with or buying a foreign business.Originality/valueInvestment flows to India for the past 15 years (2005-2019) are critically analysed to justify research questions. Further, in the literature “Preparedness of India”, a lot of new interesting insights, incorporated.

Published: February 2020

PurposeThis paper aims to investigate how knowledge sharing influences technological innovation capability (TIC) of the software small- and medium-sized enterprises (SSMEs).Design/methodology/approachBased on the theories regarding knowledge management, TIC, software engineering and open innovation, this paper constructed a research model comprising factors affecting knowledge sharing, knowledge sharing and TIC, and then tested the model quantitatively. The study focuses on SSMEs in China collecting 457 online questionnaires and uses a structural equation model to test the hypotheses.FindingsThe knowledge sharing culture, organizational structure, middle-level leadership and management system have significantly positive effects on tacit knowledge sharing; management system and IT support have significantly positive effects on explicit knowledge sharing; both explicit and tacit knowledge sharing have significantly positive effects on TIC.Research limitations/implicationsThe study enriches the research on knowledge sharing and TIC. However, it does not consider factors affecting knowledge sharing at the non-organizational level or the interaction between explicit and tacit knowledge sharing.Practical implicationsThe study offers several recommendations/suggestions for helping SSMEs to promote and implement explicit or tacit knowledge sharing and TIC.Originality/valueThis paper examines the impact of knowledge sharing on TIC from the perspective of knowledge management deconstructing knowledge sharing from the epistemological dimension and the TIC of software companies on the basis of software engineering theory. It provided a new theoretical perspective for the research of knowledge management and technological innovation management in SSMEs.
Visual storytelling on Instagram: branded photo narrative and the role of telepresence
Authors: Lim Heejin , Childs Michelle 
Published: February 2020

PurposeThe new focus of brand communication in social media has driven firms to develop the effective visual content strategy. In light of narrative transportation theory, this study aims to investigate the impact of a photo’s narrative elements on self-brand connection through viewers’ transportation and emotional responses. Additionally, this study tests the role of telepresence on Instagram in this psychological mechanism.Design/methodology/approachUsing between-subjects experimental design, two experimental studies test the effect of implied movement (Study 1) and diverse narrative elements such as a character, implied motion for chronology and the relevant background (Study 2).FindingsResults demonstrate that a single narrative element, i.e. implied motion, does not induce a viewer’s transportation to the presented image. Rather, the viewer’s transportation occurs as a function of complex and diverse narrative elements, such as implied motion and the background as a context.Practical implicationsFindings suggest that the concept of photo narrative should be taken into consideration in a visually-oriented social media environment. To increase self-brand connection, social media communication should be designed with diverse elements to promote viewers’ active simulation and create meaning to the branded photo story.Originality/valueThis study expands the theory of narrative transportation by applying it to a visual form. Additionally, this research investigates the effect of social media communication on self-brand connection; the findings of this study demonstrate that a major goal of social media communication is not to sell products but to strengthen consumer-brand relationships through branded storytelling.
Exchange ideology and employee creativity: a moderated mediation analysis
Authors: Song Zhigang , Gu Qinxuan 
Published: February 2020

PurposeThis paper aims to investigate the relationship between exchange ideology and employee creativity based on the social exchange perspective. It also attempts to examine the mediating role of perceived shared leadership and the moderating role of vertical moral leadership.Design/methodology/approachMultilevel and multisource data were collected from 56 research and development (R&D) teams with 306 employees. Hypotheses were tested with multilevel path analysis.FindingsThe authors found that exchange ideology was negatively related to both perceived shared leadership and employee creativity, and perceived shared leadership mediated the relationship between exchange ideology and employee creativity. Moreover, we revealed that vertical moral leadership buffered the negative relationship between employee exchange ideology and perceived shared leadership and also the indirect effect of exchange ideology on employee creativity via perceived shared leadership.Research limitations/implicationsOrganizations should select employees with a relatively weak exchange ideology when forming teams to conduct creative tasks. Moreover, team leaders should make great efforts to facilitate the development of shared leadership among team members while to be a moral leader.Originality/valueThis study extends creativity literature by investigating the effect of exchange ideology on employee creativity. It also sheds lights on leadership research by examining the mediating role of perceived shared leadership and the moderating role of vertical moral leadership.
Optimising nature conservation outcomes for a given region‐wide level of food production
Authors: Finch Tom , Green Rhys E. , Massimino Dario , Peach Will J. , Balmford Andrew 
Published: February 2020

Abstract

The land sharing‐sparing framework aims to quantify the trade‐off between food production and biodiversity conservation, but it has been criticized for offering, for reasons of simplicity, an unrealistically limited set of different land uses.

Here, we develop the framework to evaluate a much larger suite of land‐use strategies in which the areas and yields of three land‐use compartments - natural habitat, high‐yield farmland, and lower‐yield farmland - are varied simultaneously. For two regions of England, we use functions that relate the local population density of breeding bird species to farm yield to simulate species‐specific region‐wide population sizes under each strategy.

We find that geometric mean population size, averaged across all species, is maximized when farmland yields are higher than the current average yield, and when spared land combines both natural habitat and low‐yield farmland. This conclusion is relatively insensitive to the maximum yield considered feasible under extreme land sparing, and holds across a range of region‐wide food production targets.

To some extent, our conclusion depends on which species groups were included in the assessment. Considered alone, farmland birds preferred a strategy with little or no natural habitat. Nonetheless, the optimal strategy was broadly consistent across all widely recognized listings of species of conservation concern.

Synthesis and applications. Our study looks at landscapes with a long history of agricultural use, and which have little remaining natural habitat, such as those found in lowland England. In these landscapes, conservation outcomes are likely to be maximized by mixed strategies in which high‐yield production enables an increase in area of both natural habitat and low‐yield farmland elsewhere in the region.
The contribution of semi‐natural habitats to biological control is dependent on sentinel prey type

Published: February 2020

Abstract

It is widely recognized that landscape factors affect the biological control of weed seeds and insect pests in arable crops, but landscape effects have been found to be inconsistent between studies.

Here, we compare six different types of sentinels (surrogate prey that was either live insects or seeds) to measure the effects of semi‐natural habitats at field to landscape scales on levels of biological control in winter wheat in the UK. Sentinels were located in fields adjacent to three boundary types: grassy margin, hedgerows or woodland to study the local scale effects and in landscapes of varying heterogeneity in study areas of 1‐km radius.

Overall, mean levels of predation were higher for most insect prey (60.8%) located on the ground compared to the crop (12.2%) and was lower for seeds (5.8%). Predation of sentinels on the ground was attributed to generalist predators. Semi‐natural habitats had both positive and negative effects at field and landscape scales, but the response varied with the sentinel type. Herbaceous linear semi‐natural habitats had positive effects at local scales for Calliphora vomitoria and Sitobion avenae sentinels and provide evidence that farmers can introduce linear herbaceous features to benefit biological control. In contrast, our distance‐weighted kernel models identified a positive relationship between woody habitats and the predation of C. vomitoria and Chenopodium album. Natural aphid infestations were lower in landscapes with more semi‐natural habitat.

Synthesis and applications. Sentinels may be sensitive enough to detect variation in levels of biological control influenced by semi‐natural habitats, but this study confirms that landscape effects differ for different types of sentinel prey. This implies that it may not be possible to categorize landscapes as pest suppressive using a single sentinel type. Future studies should therefore consider using multiple sentinels to give a better perspective on predation intensity. The resulting recommendations for farm management include planting woodland adjacent wheat fields infested with seed predators and positioning herbaceous linear habitats adjacent wheat fields infested with Sitobion avenae, particularly if fields are bordered by woody liner habitats due to their association with decreased S. avenae predation.
