The purpose of this paper is to test whether household preferences satisfy the assumption of base-independence, to examine the effects of household income on equivalence scales and thereby food consumption economies of scale and to examine how far conventional poverty rates require adjustment when scale economies in food consumption are taken into consideration.

To achieve these aims, the authors use a Pendakur (1999) adaptation of the test of base-independence, and income dependent Engel (1895) equivalence scales.

In Sri Lanka, the hypothesis of base-independence is rejected: the equivalence scales increase with household income both at the national and the sectoral level, that is urban, rural and estate sectors. This suggests that low-income households enjoy greater scale economies. After adjusting for scale economies, urban, rural and estate poverty headcount ratios decline by 3.2, 8.8 and 13.7, respectively, while at the national level the decline is about 8.3.

The results are based on the assumption that all of the adults in the households have identical tastes, irrespective of their gender and age. Furthermore, the survey data exclude three districts in the northern province of Sri Lanka due to resettlement activities took place after the civil war.

Higher scale economies among the poor imply that poverty among low-income households is overstated when using traditional measures of poverty rates.

The novelty of this paper is that it provides insights on the effect of income on food consumption economies of scale and implications of this phenomenon on poverty estimates in the context of a developing country like Sri Lanka.

While the monetary returns to education are well documented in the economics literature, the studies on non-monetary returns to education are scarce. The purpose of this study is to provide new insights into the non-market outcomes by exploring how education influences the food consumption choices of households and how these effects vary across different socio-economic groups using household-level calorie consumption data from Sri Lanka.

This study uses two waves of Household Income and Expenditure Surveys – 2006/2007 and 2016. The methods adopted in analysing the data were descriptive statistics and the OLS regression model.

The empirical results show that educated poor households pay less per calorie compared to non-educated poor households, highlighting the role of education in improving the ability to make better food choices and manage household budgets more economically.

This study informs policy-makers of the importance of education for formulating food and nutritional policies, which aim to raise the standard of living of resource-poor and vulnerable households in Sri Lanka as well as other developing countries with similar socio-economic conditions.

To the best of the authors' knowledge, this study is the first to explore the impact of education on the calorie consumption behaviour of people in the Sri Lankan context using nationwide household surveys.

The task of this paper is to explore the interplay between fashion, consumer lifestyles and economic growth in the context of a world of technological change in which the menu of possibilities that consumers face is constantly changing and tending to increase in length. Our working definition of ‘fashion’ is simple, namely the tendency or behavioural norm of actors to adopt certain types or styles of customs or commodities nearly simultaneously, only to adopt a different type or style of custom or commodity in future periods. The demand spikes associated with fashion may pertain to newly introduced products or to products that have been around for some time; they may also occur in hybrid cases where a seemingly defunct product or genre is given a brief rebirth by being reincarnated in terms of a new technology.

The theory of consumer choice fills the opening chapters of any micro-economics textbook. Yet, surprisingly, this position of privilege has not translated into a flourishing of economic research that is comparable to what has happened in other branches of economic reasoning.

The purpose of this paper is to propose five organisational factors associated with abuse, neglect and/or loss of dignity of older people resident in care homes. It derives from one set of findings from the ResPECT Study of Organisational Dynamics of Elder Care commissioned by Comic Relief and Department of Health through the Prevention of Abuse and Neglect In the Care of Older Adults programme.

A knowledge synthesis method was selected to identify organisational aspects of elder mistreatment in residential care settings. The method was selected for its suitability in examining ill-defined and contested concepts such as; elder mistreatment – where the available evidence is dispersed and produced in varied forms. A rapid review comprising a search of three academic databases and a detailed examination of selected investigation reports into institutional mistreatment was followed by panel meetings with subject matter experts to complete the knowledge synthesis.

This paper identifies and elaborates five organisational factors associated with elder mistreatment; infrastructure, management and procedures, staffing, resident population characteristics and culture. It also indicates macro-structural factors affecting care quality.

Further research is needed to elaborate the influence of these organisational factors on mistreatment and to understand any interactions.

As an adjunct to personal factors, the knowledge synthesis indicates common organisational factors contributing to institutional abuse. This suggests that care quality is produced systemically and that it can collapse as a result of seemingly minor and unrelated organisational changes.

Care home safety and quality is an ongoing concern, with popular analysis frequently stopping at the point of describing individual errant behaviour. However, as “problem” organisations are closed down, “problem” organisational factors continue to recur elsewhere.

The paper identifies and elaborates organisational aspects of elder mistreatment in residential care settings. The findings are original, valuable and grounded in relevant experience by the method of analysis and synthesis of the findings from inquiry reports as well as research and the contribution to the development of findings by those central to the issue, residents, relatives and care providers.

This paper aims to uncover the combinations of knowledge sharing mechanisms that organizations in a science and technology park in Brazil use to share managerial and technical knowledge.

This research adopts a qualitative approach that uses a fuzzy set qualitative comparative analysis to analyze data that are gathered from 51 managers of organizations in a science and technology park.

The results show that knowledge sharing happens regardless of the type of knowledge. There are more alternative paths that lead to knowledge sharing than to its absence. Regarding the type of knowledge shared, there are more alternative configurations that lead to managerial knowledge sharing than to technical knowledge sharing. Only the older organizations in the science and technology park abstain from knowledge sharing.

Due to the qualitative nature of the study, no generalization is possible. Additionally, the study’s limitation is that it involves organizations from a single science and technology park.

The results offer managers of organizations in science and technology parks to choose from alternative combinations of mechanisms to either boost their knowledge sharing or to promote knowledge protection.

The paper provides an original contribution by identifying the combinations of mechanisms that organizations in a science and technology park use that leads to the sharing of specific knowledge types. The findings also identify the combination of mechanisms that older organizations use that prevents them from sharing knowledge.

This study aimed to analyze the strategies and challenges related to technology transfer (TT) in technology transfer offices (TTOs), specifically regarding actions to offer technologies in their portfolios.

The qualitative research used a multiple case study based on interviews with TTO managers from seven Brazilian public Science and Technology Institutions (STIs): University of São Paulo (USP), State University of Campinas (UNICAMP), Paulista State University (UNESP), Federal University of Minas Gerais (UFMG), Federal University of Paraná (UFPR), Federal Technological University of Paraná (UTFPR) and Oswaldo Cruz Foundation (FIOCRUZ).

STIs that invest more resources in their portfolio’s active offering and marketing are more successful in TT than STIs with a passive strategy. Although this active strategy has grown in importance, there is a disparity among Brazilian TTOs as some are still passive in commercializing their intellectual property. This research also highlights the need for clear policies to overcome obstacles related to legal uncertainty for researchers who wish to undertake projects as entrepreneurs using the intellectual property of STIs.

The results of this study cannot be generalized since its conclusions are limited to the studied institutions. However, the outcomes indicate some interesting matters for managers of STIs, public policymakers and TT researchers.

Literature on marketing and innovation related to TT between research institutions and companies in developing countries is still limited. Thus, this research contributes to generating knowledge in the field and improving TTOs.

The study builds on existing research in management control (MC) and innovation management. The purpose of this study is to identify patterns in the application of MC instruments which contribute to successful innovation. The application of MC instruments can reduce potential risks and make the new product development (NPD) process more transparent and efficient.

The authors use dyadic data to determine the effect of 58 MC instruments on NPD process stage-specific performance and subsequent innovation and firm success. To provide empirical evidence of each MC instrument’s effectiveness, three importance-performance matrix analyses were conducted that assess the impact of each MC instrument.

The authors identify patterns in the application of MC instruments which contribute to successful innovation activities and the authors determine the impact of MC instruments on NPD performance, innovation performance and firm performance in different stages of the NPD process.

The authors provide knowledge that can be used by managers to review their actual application of MC in the NPD process and to select their instrument set.

The authors contribute to the MC literature by examining data from a cross-industry study on the effects of MC instruments during the NPD process. The authors include a comprehensive set of MC instruments and show how their effect changes between the different stages of the NPD process.

Blockchain technology is predicted to revolutionize the tourism and hospitality industry through peer-to-peer hotel bookings with little or no involvement of intermediaries. Outstanding features of this technology are its distributed form of storing data, its collaborative way of identifying the “true state” of a system and the immutability of data. These features may lead to a perceived loss of controllability among travelers. Based on the Agentic Theory of Human Behavior, the purpose of this study is to propose that this assumed loss of control matters more to travelers with an individualistic rather than a collectivistic predisposition.

In two studies (n = 475 and n = 196) using verbal scenarios, this study manipulates the perceived controllability of a blockchain-enabled hotel booking app by varying the number of additional services linked to the app. This study tests for the interaction of controllability with individual-level measures of individualistic versus collectivistic (I-C) predisposition.

Collectivistic travelers are more willing than individualistic travelers to use blockchain technology for their hotel bookings. This effect can be mitigated by offering additional services that give individualistic travelers an enhanced sense of “being in control”.

Blockchain-enabled applications facilitating direct hotel bookings without any additional intermediary services are more readily accepted by travelers with a collectivistic mindset. Blockchain applications addressing individualistic travelers require added services that establish a sense of controllability.

To the best of the authors’ knowledge, this paper is the first to investigate the interaction of I-C predisposition with perceived controllability in tourism and hospitality. Furthermore, it is the first in the technology-acceptance literature to test this interaction using individual-level measures of I-C predisposition and an experimental manipulation of perceived controllability.

预计区块链技术将通过点对点酒店预订彻底改变旅游业和酒店业, 而中介机构很少或根本不参与。该技术的突出特点是其存储数据的分布式形式、识别系统“真实状态”的协作方式以及数据的不变性。这些特征可能会导致旅行者感觉失控。基于人类行为的代理理论, 我们提出这种假设的失控对具有个人主义而非集体主义倾向的旅行者更重要。

在两项使用口头场景的研究（n = 475 和 n = 196）中, 我们通过改变与应用程序链接的附加服务的数量来操纵支持区块链的酒店预订应用程序的感知可控性。我们测试了可控性与个人主义与集体主义 (I-C) 倾向的个体水平测量的相互作用。
