Soft landing control strategy for biped robot
Authors: Zhu Hongbo , Luo Minzhou , Zhao Jianghai , Li Tao 
Published: May 2017

Purpose
The purpose of this paper was to present a soft landing control strategy for a biped robot to avoid and absorb the impulsive reaction forces (which weakens walking stability) caused by the landing impact between the swing foot and the ground.

Design/methodology/approach
First, a suitable trajectory of the swing foot is preplanned to avoid the impulsive reaction forces in the walking direction. Second, the impulsive reaction forces of the landing impact are suppressed by the on-line trajectory modification based on the extended time-domain passivity control with admittance causality that has the reaction forces as inputs and the decomposed swing foot’s positions to trim off the forces as the outputs.

Findings
The experiment data and results are described and analyzed, showing that the proposed soft landing control strategy can suppress the impulsive forces and improve walking stability.

Originality/value
The main contribution is that a soft landing control strategy for a biped robot was proposed to deal with the impulsive reaction forces generated by the landing impact, which enhances walking stability.
Real-time control of bilateral teleoperation system with adaptive computed torque method
Authors: Abut Tayfun , Soyguder Servet 
Published: May 2017

Purpose
This paper aims to use the adaptive computed torque control (ACTC) method to eliminate the kinematic and dynamic uncertainties of master and slave robots and for the control of the system in the presence of forces originating from human and environment interaction.

Design/methodology/approach
In case of uncertainties in the robot parameters that are utilized in teleoperation studies and when the environment where interactions take place is not known and when there is a time delay, very serious problems take place in system performance. An adaptation rule was created to update uncertain parameters. In addition to this, disturbance observer was designed for slave robot. Lyapunov function was used to analyze the system’s position tracking and stability. A visual interface was designed to ensure that the movements of the master robot provided a visual feedback to the user.

Findings
In this study, a visual interface was created, and position and velocity control was achieved utilizing teleoperation; the system’s position tracking and stability were analyzed using the Lyapunov method; a simulation was applied in a real-time environment, and the performance results were analyzed.

Originality/value
This study consisted of both simulation and real-time studies. The teleoperation system, which was created in a laboratory environment, consisted of six-degree-of-freedom (DOF) master robots, six-DOF industrial robots and six-DOF virtual robots.
The ambidextrous manager: what role does culture play?
Authors: Hodgkinson Ian R. , Ravishankar M.N. , Fischer Michelle 
Published: May 2017

Purpose
It is known from research that the right context can help managers develop an ambidextrous approach. But just as few of us are naturally ambidextrous, many managers fail to balance conformity and change during strategy implementation. This paper aims to investigate why.

Design/methodology/approach
Through a qualitative study of managers of an international airline, the authors examine a series of cultural barriers that constrain managers’ agile decision-making and stop managerial ambidexterity.

Findings
The authors identify six culturally ingrained practices that block managerial ambidexterity: top management’s unwavering emphasis on cost control when survival hinges on fresh investments; little or no scanning of the environment for new areas of opportunity; intensive planning oriented toward efficiency issues; functional structures characterized by extensive division of labor; centralized control; and formal hierarchical communication channels.

Research limitations/implications
Managers find it difficult to put into practice new initiatives, particularly when the proposed initiatives counter the underlying cultural world of the organization. The authors suggest that this dark side of culture can pose tough barriers for ambidextrous action.

Practical implications
There is an urgent need for organizations to be aware of the possible misalignments between ambidextrous pursuits and the cultural forces that actually drive action. A deep understanding of their organization’s cultural universe is a crucial first step for managers aspiring to better engage with ambidexterity and outwit and outperform competitors.

Originality/value
Different strategic approaches need not be viewed as irreconcilable. If cultural elements do not block it, managerial ambidexterity can showcase innovative approaches to reconciling trade-offs in strategic decision-making.
Responding to open business models
Authors: Benyayer Louis-David , Kupp Martin 
Published: May 2017

Purpose
The purpose of this paper is to provide guidelines for practitioners in choosing the right response to potential threats by open business models.

Design/methodology/approach
The study focuses on identifying the dimensions of open business models. It consisted of 32 interviews with experts on open business models complemented by panel discussions with a selection of experts to validate the findings.

Findings
Five dimensions of open business models are identified: motivation, object, community, action and governance. Based on those dimensions, three responding strategies are proposed.

Practical implications
This paper offers insights for strategists and entrepreneurs who consider developing open business models or are attacked by competitors or other market players with open business models.

Originality/value
Complementing previous research, this paper highlights how the five dimensions of open business model can serve as a tool to design appropriate strategies when confronted with new forms of competition.

Authors: Holm Anna B. , Günzel-Jensen Franziska 
Published: May 2017

Purpose
The purpose of this article is to highlight the key points for succeeding with the freemium business model in online digital business from a strategic point of view. The freemium business model has recently become one of the most dominant business models in online markets. However, entrepreneurs and managers still have a limited understanding of why some freemium business models become successful and sustainable while others do not.

Design/methodology/approach
The findings and recommendations derive from the study of online digital companies and applications, which either succeeded or failed to develop a sustainable freemium model. These are LinkedIn, Spotify, Box, Eventbrite, Chargify, Gasketball and TravelCrony.

Findings
The article describes the generic strategy and the key strategic choices that enable and support successful freemium business model execution in an online digital business.

Research limitations/implications
The research is limited to digital companies applying a freemium business model and offering their products and services online.

Practical implications
The findings and recommendations can help new and existing companies, first, to evaluate if the freemium business model is feasible for them, and second, to adjust strategies to develop a successful freemium business model and scale it up.

Originality/value
The article extends the current understanding of the freemium business model logic.
Redesigning the business model: from one-sided to multi-sided
Authors: Parmentier Guy , Gandia Romain 
Published: May 2017

PurposeThis study aims to examine the way to develop a multi-sided logic for existing business models. More precisely, the objective is to find rules for designing a multi-sided business model from a one-sided business model.Design/methodology/approachGiven that business model (BM) literature and multi-sided literature do not address the complex issue of multi-sided business model design, the authors propose here a set of six redesign operations. These operations are built from a comprehension of the development and evolution of multi-sided platforms and their consequences for business model architecture. Several empirical cases illustrate each operation.FindingsA process of business model redesign is proposed with three phases: setting-up a technological digital platform to support the multi-sided architecture, identifying and engaging several customer groups on the platform and linking the customer groups and structuring the revenue model. This process details the chronological order in which the redesign operations can be implemented to build a multi-sided BM.Practical implicationsThe importance of the stage of semi-finished development of the platform, the openness of digital content, reaching the critical threshold and the combination of a dual economic model (free/paid) is highlighted. For managers, this provides better practices to successfully manage the business model redesign process.Originality/valueThis paper helps managers in companies, especially small and medium-sized enterprises, to profit from a multi-sided business model by proposing a way to achieve it.
Crowdsourcing business models that last
Authors: Kohler Thomas , Nickel Marco 
Published: May 2017

Purpose
The purpose of this paper is to discuss how to sustain crowdsourcing business models. Emerging companies are innovating their business model to rely on a crowd of participants and involve contributing users in value capture. While some organizations demonstrate initial success, sustaining a crowdsourcing business model is challenging.

Design/methodology/approach
The study is based on a comparative case study of the prominent crowdsourcing communities Threadless and Quirky. Participatory observation resulted in over 380 analyzed comments.

Findings
Seven lessons from Threadless’s success and Quirky’s failure are discussed to derive implications for sustaining crowdsourcing business models.

Research limitations/implications
Because both cases are integrator platforms build around contests, other crowdsourcing platform types should be studied to enrich the findings.

Practical implications
Managers receive guidance on how to design a sustainable business model that involves the crowd in creating value and lets the crowd participate in value capture.

Originality/value
Current research primarily addresses the question of how companies can take advantage of crowdsourcing and mainly considers corporate value capture. The original contribution of this article is a set of strategies to sustain crowdsourcing platforms by taking a platform’s entire business model into account.
Impact of non-performing loans on US product and labor markets
Authors: Ghosh Amit 
Published: May 2017

Purpose
Using time-series data on the US banking industry for the period 1984Q1-2016Q2, the present study aims to examine the impact of both aggregate and sector-specific non-performing loans (NPLs) on aggregate and sectoral product and labor markets.

Design/methodology/approach
Using both single equation ordinary least squares and instrumental variables regressions, the study compares the sensitivity of sector-specific gross domestic product (GDP) and employment growth to changes in both aggregate and sectoral NPLs. Moreover, the paper uses vector autoregressions (VARs) to dynamically trace the impact and duration of NPLs on different types of real economic activity..

Findings
Rise in total NPLs reduces US real GDP growth that is most accentuated for construction sector GDP. Likewise, total NPLs significantly lowers both total and non-farm employment growth, financial activities and construction sector employment growth, with the latter showing most sensitivity. Moreover, NPLs in commercial and industrial sector, consumer lending, non-farm non-residential, construction and land development, single- and multi-family residential sectors reduce corresponding sectoral employment growth. The VARs largely confirm these findings with shocks to total NPLs having the most immediate and persistent inimical impact on construction-sector GDP growth.

Practical implications
The deleterious impact of different categories of NPLs on both aggregate as well as sector-specific product and labor markets illustrate that a distressed banking sector is a serious obstacle to the real sector. The findings underscore the need not only to clean up NPLs for the sake of banks financial soundness but also to reduce their pernicious effects on the health of the US economy. For bank regulatory authorities in the USA, it indicates constant monitoring of banks in their jurisdiction and identifying early warning signals to mitigate the potential real sector losses due to rising NPLs.

Originality value
The extant literature on NPLs has mainly focused on explaining its underlying determinants but not on its real sector consequences. The present paper examines the impact of NPLs on different facets of real economic activity, an issue that has been rarely studied and especially not on the US economy. Moreover, the overwhelming majority of existing literature focuses on aggregate NPLs. The relationships derived in such studies, while useful, can mask important differences between different types of NPLs and real economic activity. The present paper explores the impact of disaggregated NPLs in the US banking industry on corresponding sector-specific product and labor markets, again an issue that has not been studied previously.
Do financial crises discipline future credit growth?
Authors: Amri Puspa , Chiu Eric M.P. , Richey Greg , Willett Thomas D. 
Published: May 2017

Purpose
The purpose of this paper is to test whether financial crises themselves provide some degree of ex post discipline. In other words, is there learning from the mistakes associated with crises? The authors test this hypothesis on credit growth, a frequent contributor to banking crises.

Design/methodology/approach
The study uses statistical tests (comparison of means) on a sample of 72 banking crises, the onset of which occurred between 1980 and 2008. Tests for significance of the difference are conducted using Kolmogorov–Smirnov equality in distribution tests.

Findings
The results show that real credit growth fell substantially (relative to average) by about 8 per cent points from pre- to post-crisis periods, and that average banking regulation and supervision strengthens after a crisis.

Originality/value
This paper provides empirical support for the proposition that while financial markets may fail to give sufficient warning signals before a financial crisis, they may discipline governments to undertake reforms in the aftermath of a crisis.

Authors: Panda Ajaya Kumar , Nanda Swagatika 
Published: May 2017

PurposeThe present study examines the short term dynamism and long term equilibrium relationship between the stock markets of South and Central America. It also aims to capture the dynamic conditional correlations between the stock markets using weekly returns of market benchmark indices of the respective countries spanning from 2nd week of 1995 to 4th week of December 2015 are analyzed.Design/methodology/approachThe Johansen and Juselius multivariate cointegration test, Granger causality test based vector error correction model (VECM) approach, and variance decomposition analysis were used to investigate the dynamic linkages between markets. GARCH-DCC is used to investigate the Correlation Dynamics.FindingsThis study identifies long run co-movements between the stock markets. Chile, Peru and Venezuela are the most dynamically interlinked. The empirical results VECM reveal that Argentina, Brazil, Chile and Venezuela stock market returns are significantly influenced by each other, suggesting a stronger linkages between national stock markets. Cointegration test confirms long-run equilibrium relationship. among the major stock markets of the region. The findings from GARCH-DCC provide evidence consistent with increasing market integration. Stocks exhibit asymmetries in conditional correlations. The results demonstrate that correlations are higher toward the end of the sample period than in the early phase.Research limitations/implicationsOn the basis of the results produced by the study, we conclude that there exist opportunities for diversification and investors will benefit from reduction of diversifiable risk among the South and Central American countries in general, but in particular Chile, Peru and Venezuela have not shown the same outcome.Originality/valueThis study has been conducted for a longer period of time and also uses various tools to investigate the dynamic linkages between markets.VAR, VECM, Cointegration and GARCH-DCC altogether in a single study is a rare piece of work.

FindingsThe paper finds that conducting an analysis of the causal influences of the social or public health problem helps to inform strategy development.

Originality/valueThe paper presents a planning mode that can be useful in identifying industry contributions to social problems and in anticipating industry opposition to social change. The model is particularly appropriate for developing social marketing programs in which industry involvement is present.
Travelling alone or travelling far?
Authors: French Jeff , Russell-Bennett Rebekah , Mulcahy Rory 
Published: May 2017

PurposeThis paper aims to explore the potential contributions of the for-profit sector in integrating resources with social marketing organisations for value co-creation at the meso level (midstream) of the social marketing eco-system. The paper addresses calls for further theorisation and understanding of value co-creation beyond the micro level (downstream).

Design/methodology/approachThe paper draws from social marketing, value co-creation and eco-systems literature to present a conceptual model for meso-level value co-creation between social marketing and for-profit organisations.

FindingsThe paper proposes four dimensions of resources which can be integrated: cognitive, labour, economic and network. Additionally, it is proposed that from these integrated resources, three co-creation outcomes can be achieved – co-learning, co-design and co-production – which lead to improved value propositions.

Practical implicationsThis paper offers a framework for strategic planning and evaluation regarding partnerships and collaborations with for-profit organisations, which potentially lead to greater value propositions being offered.

Originality/valueThis paper furthers the theoretical discussions and understanding of value co-creation in social marketing at the meso level. The paper identifies a new actor – for-profits – as a potential collaborator for value co-creation with social marketing organisations and contributes new understanding about value co-creation at the meso level between social marketing and for-profit organisations. Further, the paper describes and reviews the potential contributions of for-profits to social marketing efforts.
Dietary habits and food intake frequency of preschool children
Authors: Rysha Agim , Gjergji Tahire M. , Ploeger Angelika 
Published: May 2017

Purpose
The study aims to assess the dietary habits and frequency of food intake by preschool-aged children in Kosovo.

Design/methodology/approach
The study is based on a survey of meal patterning and frequency of food group intake, using a combined 24-hour recall and Dietary history questionnaires. The assessment took place in different towns of Kosovo. Parents completed 232 questionnaires with data on dietary habits and food frequency intake of their children. Intake frequencies were computed and included in the analyses.

Findings
Dietary habits and frequency of food intake for specific foods (the main typical foods from the food groups) did not show significant differences (P > 0.05) between age groups, except in terms of milk consumption (P < 0.05) and soft drinks intake (P < 0.001). It was found that the consumption of fruits and vegetables as well as other high-fiber foods is very limited.

Research limitations
Despite the limitation in terms of sample, the results can be used by Kosovo’s authorities as an indication for an assessment of child’s development patterns in the country.

Originality/value
This assessment reports for the first time the dietary habits and frequency of food intake by preschool-aged children in Kosovo. The dietary pattern was shown to be low in wholegrain products and fruits and vegetables, and high in soft drinks and sweet and salty foods. Health and education authorities should develop national programs and dietary guidelines on recommended dietary intakes.

Authors: Mohamadi Sani Ali , Sheikhzadeh Mahya 
Published: May 2017

Purpose
This paper aims to provide information on the different methods of aflatoxin (AFT) degradation in rice.

Design/methodology/approach
Crops that are affected by AFT contamination include cereals, oilseeds, spices and tree nuts. AFT in rice may harm health to great extent, and if not properly determined, may cause death. The production and occurrence of mycotoxins differ depending on the geographic and climatic and environmental conditions; however, these toxicants can never be removed completely from the food supply.

Findings
Mycotoxins are commonly present in cereal grains such as rice and are not completely destroyed during their cooking and processing.

Originality/value
No review on detoxification of AFT has been found in rice.
