Abstract
The exterior surface of a building -façade- as a communicative ground reflects the burdened meaning of its structure. Besides communicative capacity of façade, its independency, individuality and image dominancy can define exterior surface as an autonomous architectural element in terms of both physical and moral freedom. However, in the twenty-first century, this autonomy has undermined by globalization, technology and communication tools which are among the rapidly increasing activities of the century. Location of architecture in economic transactions and financial market has caused a loss in its internal dynamics and value system. The endeavor of providing the visual appeal only through the façade formation has caused the transformation in the dependency of exterior surface being devoid of content and context. The surfaces have been treated as changeable and renewable advertisement grounds concentrating on the visual appeal of the product, whether the aim is marketing, advertising or commercializing. Thus, the link between architecture and social structures has weakened through the commodification of the end product. In this framework, aim of this paper is (a) to make the description of façade, (b) to define the autonomy of façade through its physical and moral independency by examining cases and (c) to put forward a logical argument on the aspects which make façade an element pursuing only the visual pleasure by oversimplifying its significance in the generation of architectural idea.

Abstract
Purpose
The purpose of this paper is to evaluate the impact of interventions focused on reducing screen time in children.
Design/methodology/approach
Studies that aim to investigate the effects of interventions aimed at reducing the time spent in front of the screen (i.e. screen time). A Random-effects model was used to calculate the pooled standard mean differences. The outcome was to evaluate the screen time in children in the 0–18 age range. A subgroup analysis was performed to reveal the extent to which the overall effect size varied by subgroups (participant age, duration of intervention and follow).
Findings
For the outcome, the meta-analysis included 21 studies, and the standard difference in mean change in screen time in the intervention group compared with the control group was −0.16 (95% confidence interval [CI], −0.21 to −0.12) (p < 0.001). The effect size was found to be higher in long-term (=7 months) interventions and follow-ups (p < 0.05).
Originality/value
Subgroup analysis showed that a significant effect of screen time reduction was observed in studies in which the duration of intervention and follow-up was =7 months. As the evidence base grows, future researchers can contribute to these findings by conducting a more comprehensive analysis of effect modifiers and optimizing interventions to reduce screen time.

Abstract
Purpose
The literature on corporate social responsibility (CSR) neglects the link between values and their ideological underpinnings. This paper aims to fill this void by grounding the managerial values towards CSR on an ideological ground by following the Schwartz’s (1994) value framework.
Design/methodology/approach
This paper provides a theoretical construct that builds the ideological stances of different managerial values towards CSR.
Findings
The study proposes that ideologically liberal managers might be involved in CSR based on their openness to change values, whereas their conservative counterparts are likely motivated by the conservative values such as security, conformity and tradition. On the other hand, egalitarian managers can engage in CSR based on their self-transcendence values, while non-egalitarian managers might involve in CSR based on their self-enhancement values as achievement and power.
Practical implications
The study can provide to all stakeholders a new perspective and a sound reference point to understand and monitor the socially responsible behaviours of managers.
Originality/value
The proposed bases of managerial values to CSR deepen the understanding on the antecedents of CSR. Based on the study, the future studies can configure out the role of diverse values on CSR in line with their ideological roots.

To identify transitional palliative care (TPC) interventions for older adults with non-malignant chronic diseases and complex conditions.
Abstract
Purpose
To identify transitional palliative care (TPC) interventions for older adults with non-malignant chronic diseases and complex conditions.
Design/methodology/approach
A systematic review of the literature was conducted. CINAHL, Cochrane Library, Embase and Pubmed databases were searched for studies reporting TPC interventions for older adults, published between 2002 and 2019. The Crowe Critical Appraisal Tool was used for quality appraisal.
Findings
A total of six studies were included. Outcomes related to TPC interventions were grouped into three categories: healthcare system-related outcomes (rehospitalisation, length of stay [LOS] and emergency department [ED] visits), patient-related outcomes and family/carer important outcomes. Overall, TPC interventions were associated with lower readmission rates and LOS, improved quality of life and better decision-making concerning hospice care among families. Outcomes for ED visits were unclear.
Research limitations/implications
Positive outcomes related to healthcare services (including readmissions and LOS), patients (quality of life) and families (decision-making) were reported. However, the number of studies supporting the evidence were limited.
Originality/value
Studies examining the effectiveness of existing care models to support transitions for those in need of palliative care are limited. This systematic literature review identified and appraised interventions aimed at improving transitions to palliative care in older adults with advanced non-malignant diseases or frailty.

Abstract
Purpose
This paper aims to examine innovativeness and extraversion as antecedents of perceived and social media opinion leadership in different country-level contexts and explore how these antecedents influence product adoption differently.
Design/methodology/approach
A survey method was used to collect data from Turkey and the USA. A total of 415 respondents participated in two studies, and data were analyzed using structural equation modeling.
Findings
This research shows that innovativeness affects perceived opinion leadership, whereas extraversion affects social media opinion leadership, and these effects are moderated by country-level differences.
Practical implications
Tthis research provides strategic information strategic information on how to identify and target influencers in social media across countries. This paper has implications for marketers who are trying to find influential consumers to increase new product adoption. Social media opinion leaders are important seeding points, because they actively initiate new product adoption for other consumers. Marketers should create strategies that are in line with the country’s cultural orientation in addition to personal/psychological traits.
Social implications
This research provides valuable information to better explain the consumers’ adoption of technological products and the factors affecting this process in the context of social media. Specifically, this paper identifies strategies to use cultural differences across countries (i.e. Turkey versus the USA) and personality traits (i.e., innovativeness and extraversion) in the adoption of new products.
Originality/value
This paper extends prior literature on opinion leadership by uncovering consumer dynamics internationally, which are known to influence social media use. Specifically, by examining the effect of innovativeness and extraversion on opinion leadership in different countries, this research contributes to the literature on new product adoption and has implications for effectively identifying influencers in social media.

Abstract
Purpose
The present study attempts to analyze how social entrepreneurs (SEs) develop technological innovation in the face of diverse institutional logics, which are embedded in the National Systems of Innovation (NSI).
Design/methodology/approach
Based on the content analysis of Ashoka Fellows, the study compares SEs in developed and developing countries, which represent strong versus weak NSIs.
Findings
SEs selectively couple the elements of diverse institutional logics to ensure the resource inflow and legitimacy of their operations. However, SEs particularly at weak NSIs are also decoupling their profit and non-for-profit branches to address conflict among diverse logics. Moreover, the study finds that 12 out of 20 entrepreneurs who identify themselves as technologically innovative did not develop any new technological innovation.
Practical implications
The study shows that being technologically innovative depends on the acquisition of resources and the management of legitimacy challenges, SEs can diversify their innovations by creating more incremental, architectural and modular innovations to address competing demands among logics.
Social implications
The study reveals that SEs in weak NSIs interact with multiple institutional logics more frequently than their counterparts in strong NSIs. Although this context leads them to diversify their technological innovation, there is a need for improving the NSIs of SEs in developing countries to facilitate the continuity of resource inflow and ensure the legitimacy of their operations.
Originality/value
Integrating two complementary theoretical lenses, the study contributes to the literature by exploring the impact of the interaction between logics nested within a supra system and SEs’ ability to develop technological innovation.

Abstract
Purpose
Stimulant-sensitive materials exhibit physical or chemical reversible changes in their properties as a result of environmental variables. One of these materials is thermochromic materials. Materials with thermochromic sensitivity change their color with heat exchange. For this reason, it can be used in many different fields such as security inks. Such substances decompose rapidly by being affected by weather conditions. Furthermore, the particle sizes are larger than normal pigments, and therefore, it is difficult to stabilize thermochromic dyes. Because of all these adverse conditions, thermochromic colorants must be protected before use in the ink. This protection is planned to be provided by the microcapsulation technique. The purpose of this study is to determine the thermochromic printing inks that can be stored stably by microcapsulation technique, to protect it from environmental conditions and the determination of printability parameters.
Design/methodology/approach
In this study, capsules with a core material of thermochromic dyeing with polyurea formaldehyde (PUF) or poly-phenolmelamine formaldehyde (PMF) shell were synthesized at appropriate pH and temperature using the appropriate solvent and mixing speed. The chemical structure and dimensions of the obtained capsules were examined by ATR-FTIR and scanning electron microscopy, respectively. The produced thermochromic microcapsules were mixed with alkyd resin and mineral oil and screen printing ink was obtained. Printability tests such as surface morphology, color, gloss and light fastness were applied.
Findings
As a result, it was determined that PMF is not a suitable encapsulation technique for thermochromic dyes under suitable conditions and eliminates thermochromic property by providing heat stability. It was found that PUF microcapsulation can be used in thermochromic dyestuff encapsulation and does not lose the thermochromic property. It has also been found that PUF microcapsules increase the lightfastness and stability of thermochromic dye ink.
Originality/value
This study provides experimental research on the encapsulation of a thermochromic dye and its use in ink.

Abstract
Purpose
Focusing only on the characteristics of the wine and the type of production is insufficient to give a holistic idea on consumer’s organic wine consumption behavior. Therefore, this study aims to examine the impact of attitude, perceived behavioral organic wine consumption, theory of planned behavior (TPB) control and subjective norms on organic wine consumption intention and behavior.
Design/methodology/approach
Drawing on the TPB, a theoretical model was developed and tested by partial least squares structural equation modeling method. The sample of the research consists of 304 participants from the vineyards in Izmir/Turkey.
Findings
The main result of this study reveals that the theoretical model belonging to the TPB is also valid in the case of organic wine consumption behavior. Specifically, research results indicate that attitude has the strongest direct impact on intention and indirect impact on organic wine consumption behavior while perceived behavioral control has the least impact.
Originality/value
Prediction of organic wine consumption behavior from the perspective of the TPB presents the originality of this paper.

Abstract
Purpose
This study aims to analyze how corporate social responsibility (CSR) initiatives address sustainability challenges by focusing on the congruence between process and outcome variables of CSR.
Design/methodology/approach
Following a theory-driven model, a content analysis was conducted on 63 award-winning social responsibility projects.
Findings
The study reveals that the adoption of a proactive approach during environmental assessment, which manifests itself in a focus on emerging sustainability challenges with a deeper interest, affects the centrality of social responsibility initiative by increasing its learning and partnership potential and leads organizations to produce radical innovations.
Practical implications
The findings provide a valuable understanding for practitioners on organizing the decision making process of CSR initiatives in order to unlock its learning potentials.
Social implications
Radically innovative projects with their higher levels of proactivity, centrality and generalizability are better than incremental ones at transferring and integrating company resources and capabilities to address emergent sustainability challenges.
Originality/value
The impact of CSR on society and nature has been a neglected area of literature. To reduce this gap, this study analyzes how the configuration of process variables shapes the outcomes of socially responsible initiatives on sustainability. It also provides a new typology on the relevance of CSR initiatives to company mission/model that can show how CSR can unlock organizational learning and innovation potentials.

Abstract
Purpose
This study aims to examine the relationship between the quality of working lives and the perceived stress of health personnel working in a hospital specialized in physical medicine and rehabilitation services.
Design/methodology/approach
This descriptive correlational study was conducted with health personnel providing medical, sport and vocational rehabilitation in an education and research hospital. The Quality of Work Life Scale (QWLS) and the Perceived Stress Scale (PSS) questionnaires were used to collect data. Descriptive statistics were used for quantitative analysis.
Findings
There was a positive correlation between their stress scores on the QWLS and perceived stress on the PSS. The highest score on the QWLS was obtained from the dimension of working conditions (3.47), and the lowest score was obtained from the dimension of stress (1.34). The mean score on the PSS was 33.18 ± 3.29. No significant relationship was found between participants’ scores on the PSS and their demographic characteristics.
Practical implications
There is a need to improve the quality of rehabilitation providers’ working lives by reducing their work-related stress.
Originality/value
As rehabilitation personnel play an important role in protecting and promoting the health of vulnerable groups in the society, it is a main priority to examine the relationship between rehabilitation providers’ perceived stress and the quality of their working lives.
