Abstract
Purpose
Mouth segmentation is one of the challenging tasks of development in lip reading applications due to illumination, low chromatic contrast and complex mouth appearance. Recently, deep learning methods effectively solved mouth segmentation problems with state-of-the-art performances. This study presents a modified Mobile DeepLabV3 based technique with a comprehensive evaluation based on mouth datasets.
Design/methodology/approach
This paper presents a novel approach to mouth segmentation by Mobile DeepLabV3 technique with integrating decode and auxiliary heads. Extensive data augmentation, online hard example mining (OHEM) and transfer learning have been applied. CelebAMask-HQ and the mouth dataset from 15 healthy subjects in the department of rehabilitation medicine, Ramathibodi hospital, are used in validation for mouth segmentation performance.
Findings
Extensive data augmentation, OHEM and transfer learning had been performed in this study. This technique achieved better performance on CelebAMask-HQ than existing segmentation techniques with a mean Jaccard similarity coefficient (JSC), mean classification accuracy and mean Dice similarity coefficient (DSC) of 0.8640, 93.34% and 0.9267, respectively. This technique also achieved better performance on the mouth dataset with a mean JSC, mean classification accuracy and mean DSC of 0.8834, 94.87% and 0.9367, respectively. The proposed technique achieved inference time usage per image of 48.12 ms.
Originality/value
The modified Mobile DeepLabV3 technique was developed with extensive data augmentation, OHEM and transfer learning. This technique gained better mouth segmentation performance than existing techniques. This makes it suitable for implementation in further lip-reading applications.

Abstract
Purpose
Forestry carbon sink (FCS) is not only an important measure to deal with the current global climate change but also an effective way to build an ecological civilization. As an important form of implementation of FCS, the afforestation and reforestation projects under the clean development mechanism (CDM A/R) have important functions such as ecological protection and economic growth. This paper aims to evaluate the short-term and long-term impact of CDM on the county economy and its impact mechanism.
Design/methodology/approach
This paper first uses propensity score matching to match the county (treatment group). Second, this paper uses difference in difference to estimate the net effect of CDM A/R project on county economic development to reduce estimation error. Finally, the impact mechanism of implementing CDM A/R project on county economic development was tested.
Findings
The CDM A/R project has significantly promoted the development of real gross domestic product (GDP) and per capita real GDP in the region. Because of the long project cycle, this promotion is not immediate in the short term and has an obvious hysteresis effect. The longer the implementation time, the greater the promotion of the local economy will develop. The results are robust after the robustness test that uses the single-difference method. The CDM A/R project has promoted local economic growth by optimizing the local industrial structure, increasing the regional capital stock and raising the regional government’s fiscal revenue and expenditure.
Originality/value
This paper provides a critical overview of the relationship between clean development mechanism and local economic development.

Abstract
Purpose
This study identifies how self-employed older women experience and represent self-integrity – an element and source of meaningfulness – in their work, and how these experiences are intertwined with gendered ageing.
Design/methodology/approach
The authors used thematic analysis, influenced by an intersectional lens, to scrutinise qualitative data generated during a development project, with ten over 55-year-old self-employed women in Finland.
Findings
The study reveals three dominant practices of self-integrity at work: “Respecting one's self-knowledge”, “Using one's professional abilities”, and “Developing as a professional”. Older age was mostly experienced and represented as a characteristic that deepened or strengthened the practices and experiences of self-integrity at work. However, being an older woman partly convoluted that. Self-integrity as a self-employed woman was repeatedly experienced and represented in contrast to the male norm of entrepreneurship.
Originality/value
The authors contribute to the literature on gender and entrepreneurship by highlighting the processual dimensions – how integrity with self is experienced, created and sustained, and how being an older woman relates to self-integrity in self-employment. The results show a nuanced interplay between gender and age: Age and gender both constrain and become assets for older women in self-employment through older women's experiences of self-integrity.

Abstract
Rabbit syndrome (RS) is an antipsychoticinduced rhythmic motion of the mouth/lips resembling the chewing movements of a rabbit. The movement consists of a vertical-only motion, at about 5 Hz, with no involvement of the tongue. Long-term exposure to typical antipsychotics has clearly been associated with RS, but little is known of the risk of RS due to exposure to newer atypical antipsychotics. There have been isolated reports of RS in patients treated with the atypical agents risperidone, aripiprazole, olanzapine, and clozapine. We present the case history of a 44-year old female patient treated for paranoid schizophrenia for 22 years and RS during her last 10-month clozapine treatment. Background information from the literature is also discussed.

Abstract
Purpose
The purpose of this paper is to investigate the emotional contagion theory in print ads, and expand the literature of smiling to different type of smiles and gender congruency. Emotional contagion happens when an emotion is transferred from a sender to a receiver by the synchronization of emotions from the emitter. Drawing on emotional contagion theory, the authors expand this concept and propose that smiles in static facial expressions influence product evaluation. They suggest that false smiles do not have the same impact as genuine smiles on product evaluation, and the congruence between the model gender–product in a static ad and the gender of the viewer moderates the effects.
Design/methodology/approach
In Experiment 1, subjects were randomly assigned to view one of the two ad treatments to guard against systematic error (e.g. bias). In Experiment 2, it was investigated whether viewing a static ad featuring a model with a false smile can result in a positive product evaluation as was the case with genuine smiles (H3). In Experiment 3, it was assumed that when consumers evaluate an ad featuring a smiling face, the facial expression influences product evaluation, and this influence is moderated by the congruence between the gender of the ad viewer and the product H gender of the model in the ad.
Findings
Across three experiments, the authors found that the model’s facial expression influenced the product evaluation. Second, they supported the association between a model’s facial expression and mimicry synchronization. Third, they showed that genuine smiles have a higher impact on product evaluation than false smiles. This novel result enlarges the research on genuine smiles to include false smiles. Fourth, the authors supported the gender–product congruence effect in that the gender of the ad’s reader and the model have a moderating effect on the relationship between the model’s facial expression and the reader’s product evaluation.
Originality/value
Marketing managers would benefit from understanding that genuine smiles can encourage positive emotions on the part of consumers via emotional contagion, which would be very useful to create a positive effect on products. The authors improved upon previous psychological theory (Gunnery et al., 2013; Hennig-Thurau et al., 2006) showing that a genuine smile results in higher evaluation scores of products presented in static ads. The theoretical explanation for this effect is the genuine smile, which involves contraction of both zygomatic major and orbicularis oculi muscles. These facial muscles can be better perceived and transmit positive emotions (Hennig-Thurau et al., 2006).

Abstract
Purpose
The purpose of this paper is to plot out pathways for organizations to implement a customer focus. These pathways are outlined with the help of illustrative examples. A well-defined customer focus is vital for organizations to ensure that they are positioned to be in line with the customers’ actual needs.
Design/methodology/approach
This is a conceptual paper where the argumentation is built on previous research findings, the authors’ reflections and the use of illustrative case examples of companies managing to instill a customer focus.
Findings
This paper builds a framework of potential pathways toward a customer focus by considering four strategic questions related to competition, products, insights and metrics.
Practical implications
This paper encourages managers to move beyond labeling themselves as customer-oriented and to actually implement a customer focus. This study puts forth a framework with strategic questions and principles designed to help with these endeavors.
Originality/value
Many companies pay lip service to customer focus, and it is often merely part of the corporate jargon without any real connection to strategy, the business model or everyday practices. This paper addresses the issue further by highlighting the potential pathways through which an organization can achieve a customer focus.
