Published: November 2017

SUMMARYThe long-range coupling within prefrontal-hippocampal networks that account for cognitive performance emerges early in life. The discontinuous hippocampal theta bursts have been proposed to drive the generation of neonatal prefrontal oscillations, yet the cellular substrate of these early interactions is still unresolved. Here, we selectively target optogenetic manipulation of glutamatergic projection neurons in the CA1 area of either dorsal or intermediate/ventral hippocampus at neonatal age to elucidate their contribution to the emergence of prefrontal oscillatory entrainment. We show that despite stronger theta and ripples power in dorsal hippocampus, the prefrontal cortex is mainly coupled with intermediate/ventral hippocampus by phase-locking of neuronal firing via dense direct axonal projections. Theta band-confined activation by light of pyramidal neurons in intermediate/ventral but not dorsal CA1 that were transfected by in utero electroporation with high-efficiency channelrhodopsin boosts prefrontal oscillations. Our data causally elucidates the cellular origin of the long-range coupling in the developing brain.HighlightsNeonatal theta bursts, sharp waves and ripples vary along septo-temporal axisHippocampal activity times prefrontal oscillations via direct axonal projectionsSelective hippocampal targeting along septo-temporal axis causes precise firingLight stimulation of hippocampal neurons at 8 Hz boosts prefrontal oscillations
The mediating effects of ego-resilience in the relationship between organizational support and resistance to change
Authors: Ferreira Aristides Isidoro , Cardoso Carla , Braun Timo 
Published: November 2017

PurposeThis study drew upon conservation of resources and organizational support theory to develop a deeper understanding of the antecedents of affective and behavioral reactions to change processes. The purpose of this paper is to construct a theoretical framework based on previous findings of change management research to suggest that the relationship between organizational support and resistance to change is mediated by ego-resilience. This framework was then validated empirically.Design/methodology/approachTo test this model, the mediation relationship was examined using regression analysis with bootstrapping. The sample consisted of 323 employees from private and public organizations.FindingsThe results confirmed that the relationship between organizational support and affective and behavioral reactions to imposed change is mediated by ego-resilience. The theoretical model was thus validated for use in future research.Research limitations/implicationsThis study’s findings have implications for organizations regarding how managers guide their employees through change processes. The research’s limitations arise from the use of convenience non-probability sampling and cross-sectional, self-reported data, which only allow for a tentative generalizability of the results.Originality/valueThe findings show that organizational change processes are affected by factors on both the individual (i.e. ego-resilience) and organizational level (i.e. organizational support). This study’s results thus provide empirical support for the conclusion that ego-resilience mediates the indirect relationship between organizational support and employees’ resistance to change.
Business model design and firm performance
Authors: Gerdoçi Blendi , Bortoluzzi Guido , Dibra Sidita 
Published: November 2017

PurposeThe purpose of this paper is to contribute to the literature on business model (BM) design by deepening the relationship between BM design themes and performance in a sample of firms based in a developing country. In particular, the authors deepen the relationship between business model novelty (BMN), business model efficiency (BME), the trade-off between novelty and efficiency – that the authors call BM ambidexterity – and performance.Design/methodology/approachData are drawn from a sample of 107 manufacturing and service firms based in a developing country (Albania). Hierarchical regression is used to assess the impact on firm performance from the two BM design themes and their interaction.FindingsThe authors find novelty-centred BM design is significantly related to firm performance while efficiency-centred design has no direct effect on performance. However, the authors also find that BME positively moderates the relationship between BMN and firm performance.Research limitations/implicationsThe relationship between BM design and firm performance can be better understood if contextualised. In the paper, the authors find that different types of BM designs have different impacts on the performance of firms based in a developing economy. While novelty matters, quite surprisingly the authors find no support for efficiency. Additionally, the authors find the interaction between the two design themes (BM ambidexterity) to have a positive impact on firm performance.Practical implicationsThe surveyed firms based in a developing economy appear to benefit from novelty-centred BM designs. Efficiency-centred designs have a more ambiguous role: while efficiency alone seems not to pay off, an efficient BM design may facilitate the market exploitation of a novel design.Originality/valueThis study responds to a precise call for additional quantitative empirical studies on the relationship between BM and performance. The study also contributes to an emerging stream of research focused on BM ambidexterity.
Internship-related learning outcomes and their influential factors
Authors: Nghia Tran Le Huu , My Duyen Nguyen Thi 
Published: November 2017

Purpose
The purpose of this paper is to explore the experiences of Tourism and Hospitality interns in Vietnam to identify dimensions of internship-related learning outcomes and factors influencing these learning outcomes.

Design/methodology/approach
In total, 12 in-depth interviews were conducted with 12 interns to identify the dimensions of internship-related learning outcomes. Following the interview, an online survey, which was designed based on the results of content analysis of the interviews, was used to collect data from 319 interns from ten Vietnamese universities. Exploratory factor analysis, descriptive statistical analysis, independent samples t-tests, and one-way ANOVA tests were used to find answers to the research issues.

Findings
Qualitative and quantitative analysis showed that from the students’ perspective, internships helped them consolidate the existing knowledge and skills, further develop relevant professional skills, shape their career paths, and change their learning attitudes and behaviors. The analysis also indicated that student engagement and the extent to which they are involved in tasks during the internships could influence the learning outcomes they gained from the internships.

Research limitations/implications
This study completely relied on students’ perceptions and ratings.

Practical implications
The study findings indicate that universities need to pay greater attention to student engagement. By encouraging collaboration between interns and their mentors and organizing activities for interns to utilize their knowledge, universities will improve students’ learning experience during the internship.

Originality/value
This mixed-method study expands our understanding about internship-related learning outcomes and influential factors using the perspectives of interns in a developing country. It has important implications for higher education institutions and students to improve the effectiveness of internships.
Enhancing engineers’ public speaking efficacy using appreciative inquiry
Authors: Mehta Nikhil Kewalkrishna 
Published: November 2017

Purpose
Existing methods of enhancing-based public speaking efficacy are based on the deficit-based model. On the other hand, public speaking is an ability that has a potential to produce anxiety, fear of negative evaluation. The purpose of this paper was to explore the use of strength-based learning pedagogy, i.e. appreciative inquiry to work upon enhancing public speaking skills of engineers.

Design/methodology/approach
An appreciative inquiry was conducted on 15 engineers using 4D model. The data were gathered using narrative analysis and grounded theory.

Findings
Participants shared their stories of past, present and future to derive meaningful insights that have potential to bring development.

Research limitations/implications
The study has an underpinning in Deci and Ryan’s self-determination theory. As practitioners of self-determination theory open the positive space for individuals to learn, appreciative inquiry aids in opening such positive space so that learners can experiment openly without any fear of negative evaluation. It prepares them by enhancing intrinsic and extrinsic motivation.

Practical implications
The study motivated engineers to focus on effortless delivery of their speeches and eliminate other associated fear. The study can be used as a classroom pedagogy.

Social implications
As public speaking is associated with fear of negative evaluation and anxiety, it has a potential to affect self-confidence and self-image adversely. As appreciative inquiry fosters one’s confidence positively through constructionism, the appreciative inquiry can be a choice of pedagogy and has positive implications for learners at the social level.

Originality/value
The study presents a fairly novel approach as it focuses on encouraging engineers to improve their presentation skills and to focus on what they do well (rather than what their weaknesses are) so they can build their confidence.
A critical examination of government budgeting and public funds management in Nigeria
Authors: Ajibolade Solabomi Omobola , Oboh Collins Sankay 
Published: November 2017

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.
Refurbishing services and how services enhance consumer well-being
Authors: Durgee Jeffrey F. , Agopian Garo 
Published: November 2017

Purpose
The purpose of this paper is to explore how services might impact a general consumer sense of everyday well-being or life satisfaction.

Design/methodology/approach
It was decided to focus on the existential benefits of refurbishing services and see how they might impact owner sense of self and overall life satisfaction. A qualitative study was fielded which consisted of analyses of website testimonials of customers of refurbishing services for products such as pianos, watches, boats, bicycles and other durables. Also analyzed were results from one-on-one qualitative interviews of customers of refurbishing services and selected refurbishers of similar products.

Findings
The study suggests that refurbish services provide a mix of hedonic and eudaimonic benefits. They provide an enhanced sense of self and general well-being insofar, as the newly restored item connects owners to loved ones, to other collectors or fans and to their own personal life histories. It also connects them to the refurbishers and their “magic”. Insofar as refurbishers invite customer involvement in the process, they co-create how the process will proceed, so customers feel a special involvement and gain an understanding of the workings of the item and how to best use it.

Practical implications
Refurbishing services might offer, like all the new internet-mediated sharing services, a more sustainable alternative to the buy-and-dispose consumption behaviors found in most world economies.

Originality value
This paper provides insights into the lives of products after purchase and the roles of relevant service providers. It also provides examples of how service providers in general might deepen and facilitate customers’ feelings about themselves and their daily lives. It shows how service providers can enhance customer hedonic and eudaimonic appreciation of provider knowledge, skills and efforts.
Biotic and abiotic modifications of leaf litter during dry periods affect litter mass loss and nitrogen loss during wet periods
Authors: Gliksman Daniel , Haenel Sabine , Grünzweig José M. 
Published: November 2017

Abstract

Decomposition of organic matter in semi‐arid ecosystems is a key component of the terrestrial carbon (C) cycle. The well‐known inaccuracies in predicting litter decay in water‐limited regions were lessened by considering solar radiation as an abiotic decay driver of photodegradation. Moreover, exposure to high solar irradiance in dry periods often led to massive facilitation of litter decay in subsequent wet periods (“photoacceleration”), though in many studies this effect was absent.

Recently, water vapour and dew were identified as modulators enabling substantial microbial degradation during rainless periods. Here, we investigated, (1) whether the activity of micro‐organisms modifies litter traits, such as litter quality and microbial community in dry periods, consequently altering the loss of litter mass and nitrogen (N) in wet periods, and (2) whether it can co‐occur with photoacceleration.

By successively introducing litter to the field at the beginning and the end of the dry season, we found that microbial activity during the dry season affected litter mass and N loss during the wet season. Low microbial activity in the dry season led to inhibition of mass loss in the wet season, while high microbial activity led to facilitation of mass loss. Microbial activity during the dry season also caused strong inhibition of N loss from litter during the wet season, likely by enhancing the dry‐season N loss. A microclimate manipulation experiment using radiation filters showed that microbial activity and exposure to solar radiation jointly modified the litter during the dry season and affected subsequent decay in the wet season.

Knowledge of biotic and abiotic modifications of litter during dry periods and their implication for wet periods enhances our understanding of litter decay in semi‐arid regions. Furthermore, it can improve biogeochemical model predictions of C and N cycling in drylands and in the many regions that are projected to experience a drier climate during the coming decades.

Male but not female zebra finches with high plasma corticosterone have lower survival
Authors: Jimeno Blanca , Briga Michael , Hau Michaela , Verhulst Simon 
Published: November 2017

AbstractThe glucocorticoid axis is essential for coping with predictable and unpredictable environmental variation. Despite this vital function, attempts to link individual variation in the glucocorticoid axis to survival have yielded mixed results, which may be due to endocrine variation caused by uncontrolled variation in environment and life‐history traits such as reproductive effort. We therefore studied the link between the glucocorticoid axis and long‐term survival using captive non‐breeding zebra finches.We quantified the relationship between survival over a three‐year period and plasma corticosterone concentrations: (1) baseline, (2) stress‐induced, (3) after induction of negative feedback via dexamethasone injection and (4) after maximal adrenal stimulation via adrenocorticotropin hormone injection.Only stress‐induced corticosterone predicted survival, with higher concentrations being associated with lower survival. However, this effect differed significantly between the sexes, being present only in males.Stress‐induced corticosterone concentration is the sum of baseline corticosterone and the corticosterone increase in response to the standardized stressor, and both components were similarly associated with male survival in a model that included both variables. This implies that baseline corticosterone itself also exerts an effect on male survival, but this was only revealed when the stress‐induced corticosterone increase was included in the model, presumably because this increased statistical power.Given that corticosterone concentrations are highly repeatable in our study population and independent of manipulated foraging conditions, these data suggest that endocrine stress reactivity may be a major component determining male life span, presumably also in wild populations.Aplain language summaryis available for this article.
Towards a New Conceptualization of Innovation in Space: Territorial Patterns of Innovation
Authors: Capello Roberta 
Published: November 2017

AbstractThis article investigates the way in which regions innovate. Its conceptual framework departs from the simple notion that scientific activities equate with knowledge, which assumes that the presence of local knowledge produced by research centres, universities and firms is a necessary and sufficient condition for increasing the innovative capacities in local firms, fed by local spillovers. In particular, the paradigmatic jump in interpreting regional innovation processes lies in a conceptual framework interpreting not a single phase of the innovation process, but the different modes of performing different phases of the innovation process. This article conceptually identifies different territorial patterns of innovation and highlights the context conditions (internal and external to the region) that accompany each innovation pattern. Based on this debate, I express some doubts on the usefulness of EU policy aims for achieving a figure of 3% of the EU's GDP (public and private) to be invested in R&D/innovation and instead strongly support normative suggestions towards thematically and regionally focused innovation policies.
Spatial Spillovers Revisited: Innovation, Human Capital and Local Dynamics
Authors: Baycan Tuzin , Nijkamp Peter , Stough Roger 
Published: November 2017

AbstractThis symposium focuses on understanding key territorial‐level innovation trends and processes by country, region and technology. It questions various widely accepted assumptions, offers fresh perspectives, both conceptually and methodologically, and challenges a paradigm shift in the field of innovation and spatial dynamics. It consists of three articles analysing at different scales (urban, regional and national) the territorial dynamics of innovation and their determinants. The innovation process, with local symbiosis and spatial spillovers at its core, is analysed within the conceptual framework of national and regional innovation systems and regional economic development. Based on a discussion of spatial spillovers and the way they shape the evolutionary and symbiotic relationships between local agents and actors, including university, industry and local development agencies, the symposium highlights the relevance of this framework for a better understanding of the transformation of local economic development processes. It investigates the differences in the geography of innovation regarding different institutional settings, different systems of innovation, and different national innovation strategies. While addressing mainly the EU, the US, and emerging countries such as China and India, the contributions also highlight the critical role of current innovation policies from a general perspective. In so doing, the symposium recognizes a contrarian perspective that argues that contemporary information and communication technologies (ICTs) provide a way to leapfrog the dominant role of proximity in innovation processes, creating a complimentary rather than a substitution effect for more remote and peripheral places. That said, this symposium focuses primarily on an urban network view of the innovation process and proximal effects in this context.
Emergent literacy skills for five kindergartners with autism spectrum disorder: a pilot study
Authors: Kimhi Yael , Achtarzad Meital , Tubul‐Lavy Gila 
Published: November 2017

In typical development, emergent literacy skills predict successful reading abilities. Code‐related literacy skills may include letter knowledge, print concepts, early writing and early phonological awareness. Meaning‐related literacy skills may include lexical and grammatical ability, story retelling and comprehension. Children with ASD (autism spectrum disorder) show, on the most part, poor reading comprehension abilities, yet up to date, research regarding emergent literacy skills in ASD is limited. We conducted a study to investigate a naturalistic, standards‐based national literacy programme, for five kindergartners with ASD, of age 5‐8 years in their kindergarten setting. We implemented an ASD‐adapted intervention as an intensive group treatment over 6 weeks, with a pretest–posttest design to examine emergent literacy gains. The children with ASD demonstrated gains in both code‐related and meaning‐related skills following intervention. The clinical and theoretical implications are discussed regarding the importance of an intensive structured literacy intervention for children with ASD before entering school.
Acquirer Internal Control Weaknesses in the Market for Corporate Control
Authors: Darrough Masako , Huang Rong , Zur Emanuel 
Published: November 2017

AbstractThis paper examines how disclosures regarding internal controls, required by sections 302 and 404 of the Sarbanes‐Oxley Act of 2002 (SOX), affect the market for corporate control. We hypothesize that acquirers with internal control weaknesses (ICWs) make suboptimal acquisition decisions based on poor‐quality information generated by their ineffective controls over financial reporting. We expect that such acquirers will be more likely to misestimate the value of their targets or the potential synergies from mergers, thereby overpaying for completed deals. Using a treatment sample of acquisitions made by acquirers that have disclosed ICWs and two matched control samples without ICW disclosures, we document that ICW acquirers experience a substantially more negative market response to acquisition announcements and have lower future performance than the two matched control samples without ICW disclosures. Overall, our results suggest that ineffective internal controls hinder decision making related to mergers and acquisitions (M&A).
