Large-Scale Synthesis of Palladium Concave Nanocubes with High-Index Facets for Sustainable Enhanced Catalytic Performance
Authors: Xie Xiaobin , Gao Guanhui , Pan Zhengyin , Wang Tingjun , Meng Xiaoqing , Cai Lintao 
Published: February 2015

AbstractThe catalytic activity of palladium (Pd) nanostructures highly relies on their size and morphology, especially enclosed with high-index facets, which provide more active sites so as to enhance their catalytic performance comparing with their low-index facet counterparts. Herein, Pd concave nanocubes enclosed with {730} facets by a one-pot scalable liquid method, with various high-index facets are synthesized via tuning reduction kinetics. Due to their high-index facets, the Pd concave nanocubes exhibit much higher electrocatalytic activity and stability for methanol oxidation than the Pd nanocubes enclosed by {100} facets and commercial Pd/C. Furthermore, we scale up synthesis of Pd concave nanocubes by expanding the volume of all species to fifty times with high-yield production.
Revealing backward rescattering photoelectron interference of molecules in strong infrared laser fields
Authors: Li Min , Sun Xufei , Xie Xiguo , Shao Yun , Deng Yongkai , Wu Chengyin , Gong Qihuang , Liu Yunquan 
Published: February 2015

AbstractPhotoelectrons ionized from atoms and molecules in a strong laser field are either emitted directly or rescattered by the nucleus, both of which can serve as efficiently useful tools for molecular orbital imaging. We measure the photoelectron angular distributions of molecules (N2, O2 and CO2) ionized by infrared laser pulses (1320 nm, 0.2 ~ 1 × 1014 W/cm2) from multiphoton to tunneling regime and observe an enhancement of interference stripes in the tunneling regime. Using a semiclassical rescattering model with implementing the interference effect, we show that the enhancement arises from the sub-laser-cycle holographic interference of the contributions of the back-rescattering and the non-rescattering electron trajectory. It is shown that the low-energy backscattering photoelectron interference patterns have encoded the structural information of the molecular initial orbitals and attosecond time-resolved dynamics of photoelectron, opening new paths in high-resolution imaging of sub-Ångström and sub-femtosecond structural dynamics in molecules.
Two-component energy spectrum of cuprates in the pseudogap phase and its evolution with temperature and at charge ordering
Authors: Gor'kov Lev P. , Teitel'baum Gregory B. 
Published: February 2015

AbstractIn the search for mechanisms of high-temperature superconductivity it is critical to know the electronic spectrum in the pseudogap phase from which superconductivity evolves. The lack of angle-resolved photoemission data for every cuprate family precludes an agreement as to its structure, doping and temperature dependence and the role of charge ordering. Here we show that, in the entire Fermi-liquid-like regime that is ubiquitous in underdoped cuprates, the spectrum consists of holes on the Fermi arcs and an electronic pocket. We argue that experiments on the Hall coefficient identify the latter as a permanent feature at doped hole concentration x > 0.08–0.10, in contrast to the idea of the Fermi surface reconstruction via charge ordering. The longstanding issue of the origin of the negative Hall coefficient in YBCO and Hg1201 at low temperature is resolved: the electronic contribution prevails as mobility of the latter (evaluated by the Dingle temperature) becomes temperature independent, while the mobility of holes scattered by the short-wavelength charge density waves decreases.
Material Parenting: How the Use of Goods in Parenting Fosters Materialism in the Next Generation
Authors: Richins Marsha L. , Chaplin Lan Nguyen 
Published: February 2015

Abstract
This research introduces the concept of material parenting, in which parents use material goods to express their love or to shape children’s behavior. Despite the common use of material goods for these purposes, possible long term effects of material parenting practices have not been studied. This article addresses this oversight by examining the potential effects of material parenting on the material values of children once they’re grown. This research proposes and tests a material parenting pathway, in which warm and supportive parents provide children with material rewards that in the long run foster materialism in adulthood. An insecurity pathway to materialism, previously proposed in the literature, is also examined. Results from three survey studies provide support for both pathways. Results also suggest that material parenting may influence children’s material values by (possibly unintentionally) encouraging them to use possessions to shape and transform the self.

The future of leadership development: how can L&D professionals design and develop our next generation of leaders?
Authors: Meager Karen , McLachlan John 
Published: February 2015

Purpose
– The purpose of this paper is to inform L&D Professionals of our research finding and the key highlights from our published book, so that they can use this information when reviewing or designing Leadership Development Programmes.

Design/methodology/approach
– We wanted to discover the common themes present in successful leadership. We researched over 60 leaders from businesses of various sizes and structures. They completed a set of multiple choice questions (personality profiling questions) and then we asked them a set of open question to identify their likes/dislikes, keys to success, areas for development, values and main issues they face.

Findings
– We found that the leaders profiled across a broad spectrum of personality types (from the multiple choice questions), and yet there were strong similarities in the themes in the open question answers. We concluded that successful leadership was not dependant on a personality type but could be developed and learnt while staying true to your own personality.

Research limitations/implications
– We would have liked to research more leaders and define the research specifically by type of organization. As the purpose of the research was to inform our writing of a useful and practical leadership development book, we did not feel it was essential for this purpose.

Practical implications
– We would like this to inform the shape of future leadership development towards a more “whole person” development and away from the traditional skills-based approach. This will support leaders to be healthier, more successful and better role models.

Social implications
– Leaders are one of the most important roles in the world, and we need healthier, more rounded, emotionally regulated, more focused leaders to be appropriate role models for future generations. It is also important that a diverse range of leadership styles is accepted and developed in organizations.

Originality/value
– What is new in our paper is the development of the idea, supported by our research that Leaders can be authentic and successful without the need for a personality transplant. We have brought together our research with our psychological qualifications and business experience to produce a leadership development approach that is deep in its thinking and construction but easy and practical to use and apply.
Nurse managers’ role in older nurses’ intention to stay
Authors: Armstrong-Stassen Marjorie , Freeman Michelle , Cameron Sheila , Rajacic Dale 
Published: February 2015

Purpose– The purpose of this paper is to propose and test a model of the underlying mechanisms linking perceived availability of human resource (HR) practices relevant to older nurses and older nurses’ intentions to stay with their hospitals.Design/methodology/approach– Quantitative data were collected from randomly selected older registered nurses (N=660) engaged in direct patient care in hospitals in Canada. Structural equation modelling was used to test the hypothesized model.Findings– The relationship between perceptions of HR practices (performance evaluation, recognition/respect) and intentions to stay was mediated by the perceived fairness with which nurse managers managed these HR practices and nurse manager satisfaction. When nurse managers were perceived to administer the HR practices fairly (high perceived procedural justice), older nurses were more satisfied with their nurse manager and, in turn, more likely to intend to stay.Research limitations/implications– The cross-sectional research design does not allow determination of causality.Practical implications– It is important that nurse managers receive training to increase their awareness of the needs of older nurses and that nurse managers be educated on how to manage HR practices relevant to older nurses in a fair manner. Equally important is that hospital administrators and HR managers recognize the importance of providing such HR practices and supporting nurse managers in managing these practices.Originality/value– The findings increase the understanding of how HR practices tailored to older nurses are related to the intentions of these nurses to remain with their hospital, and especially the crucial role that first-line nurse managers play in this process.
Organizing integrated care for older persons: strategies in Sweden during the past decade
Authors: Berglund Helene , Blomberg Staffan , Dunér Anna , Kjellgren Karin 
Published: February 2015

Purpose
– The purpose of this paper is to describe and analyse ways of organizing integrated care for older persons in Sweden during the past decade.

Design/methodology/approach
– The data consist of 62 cases of development work, described in official reports. A meta-analysis of cases was performed, including content analysis of each case. A theoretical framework comprising different forms of integration (co-ordination, contracting, co-operation and collaboration) was applied.

Findings
– Co-operation was common and collaboration, including multiprofessional teamwork, was rare in the cases. Contracting can be questioned as being a form of integration, and the introduction of consumer choice models appeared problematic in inter-organization integration. Goals stated in the cases concerned steering and designing care, rather than outcome specifications for older persons. Explicit goals to improve integration in itself could imply that the organizations adapt to strong normative expectations in society. Trends over the decade comprised development of local health care systems, introduction of consumer choice models and contracting out.

Research limitations/implications
– Most cases were projects, but others comprised evaluations of regular organization of integrated care. These evaluations were often written normatively, but constituted the conditions for practice and were important study contributions.

Practical implications
– Guiding clinical practice to be aware of importance of setting follow-up goals.

Social implications
– Awareness of the risk that special funds may impede sustainable strategies development.

Originality/value
– A theoretical framework of forms of integration was applied to several different strategies, which had been carried out mostly in practice. The study contributes to understanding of how different strategies have been developed and applied to organize integrated care, and highlights some relationships between integration theory and practice.
A degradation model for maintenance improvement in respect of cost and availability
Authors: Letot Christophe , Dehombreux Pierre , Rivière-Lorphèvre Edouard , Fleurquin Guillaume , Lesage Arnaud 
Published: February 2015

Purpose
– The purpose of this paper is to highlight the need for degradation data in order to improve the reliability and the mean residual life estimation of a specific item of equipment and to adapt the preventive maintenance tasks accordingly.

Design/methodology/approach
– An initial reliability model which uses a degradation-based reliability model that is built from the collection of hitting times of a failure threshold. The proposed maintenance model is based on the cost/availability criterion. The estimation of both reliability and optimum time for preventive maintenance are updated with all new degradation data that are collected during operating time.

Findings
– An improvement for the occurrences of maintenance tasks which minimizes the mean cost per unit of time and increases the availability.

Practical implications
– Inspection tasks to measure the degradation level should be realized at least one time for each item of equipment at a specific time determined by the proposed methodology.

Originality/value
– The introduction of a criterion which helps the maintainer to decide to postpone or not the preventive replacement time depending on the measured degradation level of a specific item of equipment.
From export entry to de-internationalisation through entrepreneurial attributes
Authors: Lafuente Esteban , Stoian Maria-Cristina , Rialp Josep 
Published: February 2015

Purpose– The purpose of this paper is to examine export behaviour from a broad perspective considering the influence of entrepreneurial attributes on export entry, export sustainability and de-internationalisation in Romanian small- and medium-sized enterprises (SMEs).Design/methodology/approach– Based on theoretical underpinnings from the resource-based view (RBV) of the firm and the Institutional Economics (IE) framework, the proposed hypotheses are tested with a rich survey data set of 319 Romanian SMEs. The data are analysed by means of a multinomial logit regression.Findings– The study reveals that exporting is not a single event and that variables commonly used to study export propensity linked to the entrepreneurial attributes have a differential influence over the export decisions. More concretely, export entry is positively impacted by the presence of management studies and an entrepreneurial team while sustainment in the international arena is strongly and positively influenced by decision-makers’ prior labour experience. De-internationalisation is explained by the entrepreneurs’ fear of business failure. The conclusions of this study point towards a holistic view of export policy making revealing relevant implications for SMEs’ internationalisation.Originality/value– This study enriches the international business literature by simultaneously examining different export decisions, namely export initiation, sustainability and de-internationalisation, at the SMEs’ level in a Central and Eastern European (CEE) emerging market. The paper also highlights the dynamic character of entrepreneurial resources and suggests that at distinct stages in the international development of a SME, different entrepreneurial attributes may play a significant role.
Contextual and cultural determinants of entrepreneurship in pre- and post-revolutionary Tunisia
Authors: Touzani Mourad , Jlassi Fahd , Maalaoui Adnan , Bel Haj Hassine Rabi 
Published: February 2015

Purpose
– The purpose of this paper is to explore the motivations and inhibitions linked to the entrepreneurial act in Tunisia, a country belonging to the Middle East and North Africa (MENA) region. The findings of such a study help to better understand why new graduates are reluctant to create their own firms in spite of the political efforts made by the government.

Design/methodology/approach
– A qualitative approach is adopted. It is based on 38 semi-directive in-depth interviews conducted with new graduates in entrepreneurship, some of them being young entrepreneurs, and others who did not go through the entrepreneurial process. On the basis of the data collected, a thematic content analysis has been carried out.

Findings
– A set of contextual and cultural factors has been highlighted by the analysis. When the context is characterised by poverty, mafia, corruption, or even by a popular revolution or a war in a neighbouring country, these factors may significantly affect new graduates’ decision to create their own firm. Besides, the entrepreneurial decision may be affected by cultural factors: the bureaucratic system, autocracy, and the existence of entrepreneurial milieus such as social class, region, and geographical regions.

Research limitations/implications
– The inductive qualitative approach adopted in a research study affects the generalisable character of the results. This study is also geographically limited to the great Tunis area (the capital and its suburbs).

Originality/value
– This study has been carried out in a context of an emergent country from the MENA region. This special setting leads to the valorisation of an understudied set of contextual and cultural motivations and inhibitors of entrepreneurship.
Governance, firm-level characteristics and their impact on the client’s voluntary sustainability disclosures and assurance decisions
Authors: Kend Michael 
Published: February 2015

Purpose– The purpose of this study is to consider three distinct bodies of literature and uses stakeholder theory as the premise of this study. The first deals with corporate sustainability reporting and voluntary disclosure behaviour, and corporate governance at the firm level, the second deals with the decision to utilize assurance services (voluntary adoption) and the third relates to the choice of auditor/assurance provider.Design/methodology/approach– This study investigates these issues using archival data from some of the Top 200 listed companies in 2010 from the countries Australia and the UK. The final matched-pair sample consists of 220 listed companies.Findings– The study finds that audit client size and the strength of corporate governance structures are significant in explaining the decision to produce a standalone sustainability report. Whereas few of these variables provide any explanatory value on the voluntary decision to assure the sustainability report, the existence of an active and diligent audit committee does have positive significance. Finally, the existence of an active and diligent sustainability committee is significant in explaining the choice of assurance provider where a member of the auditing profession was selected by the firm’s management.Originality/value– Few studies (if any), have found a link between governance characteristics, sustainability report production, and assurance provider. The current study attempts to address this knowledge gap, and also considers the assurance work by professionals outside the auditing profession, and identifies which governance and firm-level characteristics may explain demand for their assurance services. This current study, assists to understand the low incidence of assurance and what might be necessary to increase demand for this type of assurance.
Five ways to hack and cheat with bring‐your‐own‐device electronic examinations
Authors: Dawson Phillip 
Published: February 2015

AbstractBring‐your‐own‐device electronic examinations (BYOD e‐exams) are a relatively new type of assessment where students sit an in‐person exam under invigilated conditions with their own laptop. Special software restricts student access to prohibited computer functions and files, and provides access to any resources or software the examiner approves. In this study, the decades‐old computer security principle that ‘software security depends on hardware security’ is applied to a range of BYOD e‐exam tools. Five potential hacks are examined, four of which are confirmed to work against at least one BYOD e‐exam tool. The consequences of these hacks are significant, ranging from removal of the exam paper from the venue through to receiving live assistance from an outside expert. Potential mitigation strategies are proposed; however, these are unlikely to completely protect the integrity of BYOD e‐exams. Educational institutions are urged to balance the additional affordances of BYOD e‐exams for examiners against the potential affordances for cheaters.
Across‐ecoregion analysis suggests a hierarchy of ecological filters that regulate recruitment of a globally invasive fish
Authors: Bajer P. G. , Cross T. K. , Lechelt J. D. , Chizinski C. J. , Weber M. J. , Sorensen P. W. 
Published: February 2015

AbstractAimEven successful invaders are abundant only in a fraction of locales they inhabit. One of the main challenges in invasion ecology is explaining processes that drive these patterns. We investigated recruitment of a globally invasive fish, common carp (Cyprinus carpio), across three ecoregions to determine the role of environmental characteristics, predatory communities and propagule pressure on the invasion process at coarse and fine spatial scales.LocationLakes across Northern Forest, Temperate Forest and Great Plains ecoregions of North America.MethodsWe used data from 567 lakes to model presence or absence of carp recruitment using environmental conditions (lake clarity, area, maximum depth), native predatory fishes (micropredators, mesopredators, large predators) and propagule pressure (abundance of adult carp). We formed a set of alternative models and evaluated their support using an information theoretic approach. Once most supported models were identified, we used classification tree to determine how variables included in these models interacted to affect carp recruitment. Finally, we conducted a field experiment to test the predictions of the classification tree analysis.ResultsCarp recruitment was strongly regulated by processes associated with water clarity, which appeared to function as a broad‐scale ecological filter. Carp were unlikely to recruit in clear, oligotrophic lakes (Secchi depth > 2 m) despite the presence of adults in many such systems. Recruitment was more likely to occur in regions with turbid lakes, but abundant micropredators could inhibit it there.Main conclusionsCarp recruitment and invasions across large geographic areas are attributable to a two‐layer ecological filter with lake clarity/productivity acting as a coarse‐scale filter and micropredators acting as a fine‐scale filter. This two‐layer filter might explain the complex patterns of carp invasions among and within different ecoregions. Ecological filters may also explain the success of other aquatic invaders that show similarly patchy spatial distribution patterns.
