Marginalised identities between fatalism and desperation – experiences of low-level cannabis street dealers in Frankfurt
Authors: Werse Bernd 
Published: August 2021

Purpose
This paper aims to research people who sell cannabis in public spaces known as “drug places” in Frankfurt, Germany. A particular focus is set to the relations of identity formation, relations to other dealers and law enforcement, taking into account the concept of “street capital” as social and cultural capital accumulated in the practice of drug dealing in public.

Design/methodology/approach
Nine biographically oriented qualitative interviews were conducted directly within the respective “drug places” in the inner city and the margins of the local open drug scene with exclusively male subjects. Interviews were conducted in German, audio-recorded and transcribed. Data was analysed with structured qualitative content analysis.

Findings
All respondents had some degree of migration background, ranging from German citizens up to refugees with illegal residence permit status. Social deprivation, socio-cultural conflicts with parents, combined with often early own drug use (mainly cannabis and cocaine) and stigma had contributed to a precarious existence. Experiences of criminalisation did not discourage the respondents from the continuation of their selling activity. Violence in these settings was likely but assessed in highly different ways depending on attitudes and experiences. The same is true for diverging experiences with police, however, the threat of being criminalised is always present.

Originality/value
As mostly independent and solitary dealers, this study researched a rarely investigated group. While these respondents have developed skills or street capital to survive in the respective setting, they are caught between unfavourable social conditions, social exclusion, violence, law enforcement and own drug use, leading to a desperate and fatalistic mindset. Somewhat paradoxically, this fatalism may be regarded as a result of keeping control over their own actions.
Taylor-rider-based deep convolutional neural network for image forgery detection in 3D lighting environment
Authors: Vinolin V. , Sucharitha M. 
Published: August 2021

PurposeWith the advancements in photo editing software, it is possible to generate fake images, degrading the trust in digital images. Forged images, which appear like authentic images, can be created without leaving any visual clues about the alteration in the image. Image forensic field has introduced several forgery detection techniques, which effectively distinguish fake images from the original ones, to restore the trust in digital images. Among several forgery images, spliced images involving human faces are more unsafe. Hence, there is a need for a forgery detection approach to detect the spliced images.Design/methodology/approachThis paper proposes a Taylor-rider optimization algorithm-based deep convolutional neural network (Taylor-ROA-based DeepCNN) for detecting spliced images. Initially, the human faces in the spliced images are detected using the Viola–Jones algorithm, from which the 3-dimensional (3D) shape of the face is established using landmark-based 3D morphable model (L3DMM), which estimates the light coefficients. Then, the distance measures, such as Bhattacharya, Seuclidean, Euclidean, Hamming, Chebyshev and correlation coefficients are determined from the light coefficients of the faces. These form the feature vector to the proposed Taylor-ROA-based DeepCNN, which determines the spliced images.FindingsExperimental analysis using DSO-1, DSI-1, real dataset and hybrid dataset reveal that the proposed approach acquired the maximal accuracy, true positive rate (TPR) and true negative rate (TNR) of 99%, 98.88% and 96.03%, respectively, for DSO-1 dataset. The proposed method reached the performance improvement of 24.49%, 8.92%, 6.72%, 4.17%, 0.25%, 0.13%, 0.06%, and 0.06% in comparison to the existing methods, such as Kee and Farid's, shape from shading (SFS), random guess, Bo Peng et al., neural network, FOA-SVNN, CNN-based MBK, and Manoj Kumar et al., respectively, in terms of accuracy.Originality/valueThe Taylor-ROA is developed by integrating the Taylor series in rider optimization algorithm (ROA) for optimally tuning the DeepCNN.
Reflecting on languaging in written narratives to enact personal relations
Authors: Beach Richard , Caraballo Limarys 
Published: August 2021

Purpose
Unlike formalist and functional approaches to literacy and teaching writing, a languaging theory approach centers on the dynamic and interpersonal nature of writing. The purpose of this study was to determine students’ ability to engage in explicit reflection about their languaging actions in response to their personal narrative writing to determine those types of actions they were most versus less likely to focus on for enacting relations with others, as well as how they applied their reflections to subsequent interactions with others.

Design/methodology/approach
In this qualitative study, thirty seven 12th grade students were asked to write personal narratives and then reflect in writing on their use of languaging actions in their narratives based on specific prompts. Students’ explicit reflections about their narratives were coded based on their reference to seven different types of languaging actions for enacting relations with others.

Findings
Students were most likely to focus their reflections on making connections, understandings, collaboration and support by and for others as well as expression of emotions, getting feelings out, sharing issues; followed by references to conflicts, arguing, stress, negative perceptions or exclusion; references to ideas or impressions about ethics, respect, values, morals; use of “insider language;” slang, jargon, dialects; use of humor, joking, parody; and references to adult and authorities’ perceptions or influences.

Research limitations/implications
This research was limited to students’ portrayals of their languaging actions through writing as opposed to observations of their lived-world interactions with others.

Practical implications
These results suggest the value of having students engage in explicit reflections about their languaging actions portrayed in narratives as contributing to their growth in use of languaging actions for enacting relations with others.

Social implications
Students’ ability to reflect on their language actions enhances their ability to enact social relations.

Originality/value
A languaging perspective provides an alternative approach for analyzing reflections on types of languaging actions.
The pandemic and homeless people in the Turin area: the level of housing adequacy shapes experiences and well-being
Authors: Leonardi Daniela , Stefani Silvia 
Published: August 2021

Purpose
Considering the case study presented, the purpose of this paper is to analyse the impact of the pandemic in local services for homeless people. Drawing from the concept of ontological security, it will be discussed how different services’ levels of “housing adequacy” shaped remarkably different experiences of the pandemic for homeless people and social workers in terms of health protection and agency.

Design/methodology/approach
This paper focuses on a case study concerning homeless services for people during the COVID-19 pandemic in the metropolitan and suburban area of Turin, in Northern Italy. In-depth interviews with social workers and participant observation during online meetings of workers from the shelters constitute the empirical data that have been collected during the first wave of the pandemic in Italy.

Findings
According to the findings, the pandemic showed shelters as unsafe places that reduce homeless people’s decision power and separate them from the rest of the citizenship. Instead, Housing First projects emerged as imore inclusive and safermore inclusive and safer spaces, able to enhance people’s power over their own lives. The pandemic did not create emerging issues in the homeless services system or discontinuities: rather, it amplified pre-existing problematic aspects.

Originality/value
The case study presented provides empirical insights to recognise at the political and organisational level the importance of housing as a measure of individual and collective security, calling for an intervention to tackle homelessness in terms of housing policies rather than exclusively social and emergency treatment.
Insights on the glass ceiling for immigrant women entrepreneurs in the technology sector
Authors: Pugalia Sancheeta , Cetindamar Dilek 
Published: August 2021

PurposeTechnology sector is the pivotal element for innovation and economic development of any country. Hence, the present article explores past researches looking into challenges faced by immigrant women entrepreneurs in technology sector and their corresponding response strategies.Design/methodology/approachThis study employs a systematic literature review (SLR) technique to collate all the relevant literature looking into the challenges and strategies from immigrant women entrepreneur's perspective and provide a comprehensive picture. Overall, 49 research articles are included in this SLR.FindingsFindings indicate that immigrant status further escalates the human, financial and network disadvantages faced by women who want to start a technology-based venture.Originality/valueThis paper contributes to the literature by categorizing the barriers and strategies on a 3 × 2 matrix reflecting the origins of the barrier or strategy (taking place at the individual, firm or institutional level) versus the type of the barrier or strategy (arising from being an immigrant woman and being a woman in the technology sector). After underlining the dearth of studies in the literature about the complex phenomenon of immigrant WEs in the technology sector, the paper points out several neglected themes for future research.
The effects of tourism on housing prices: applying a difference-in-differences methodology to the Portuguese market
Authors: Cunha António Manuel , Lobão Júlio 
Published: August 2021

Purpose
This paper aims to explore the effects of a surge in tourism short-term rentals (STR) on housing prices in municipalities within Portugal’s two largest Metropolitan Statistical Areas.

Design/methodology/approach
This study applies the difference-in-differences (DiD) methodology by using a feasible generalized least squares (FGLS) estimator in a seemingly unrelated regression (SUR) equation model.

Findings
The results show that the liberalization of STR had a significant impact on housing prices in municipalities where a higher percentage of housing was transferred to tourism. This transfer led to a leftward shift in the housing supply and a consequent increase in housing prices. These price increases are much higher than those found in previous studies on the same subject. The authors also found that municipalities with more STR had low housing elasticities, which indicates that adjustments to the transfer of real estate from housing to tourism were made by increasing house prices, and not by increasing supply quantities.

Practical implications
The study suggests that an unforeseen consequence of allowing property owners to transfer the use of real estate from housing to other services (namely, tourism) was extreme housing price increases due to inelastic housing supply.

Originality/value
This is the first time that the DiD methodology has been applied in real estate markets using FGLS in a SUR equation model and the authors show that it produces more precise estimates than the baseline OLS FE. The authors also find evidence of a supply shock provoked by STR.
Instructional coaches' framing of a mathematics reform
Authors: Higgins Joanna , Parsons Ro 
Published: August 2021

PurposeInstructional coaches are pivotal to articulating the agenda of system-wide reform, yet their role remains largely unexamined. Their approach with educators is contextually situated within the schooling system in which they work to reflect the historical and sociocultural system influences. Given the downward trend in New Zealand's international test scores for mathematics, it is timely to review the role of instructional coaches.Design/methodology/approachIn this paper, the authors draw on qualitative data derived from interviews with experienced coaches to investigate how they brokered the vision and pedagogy of a system-level reform in mathematics. Using a sensemaking lens we specifically examined the collective stories they employed as explanatory tools.FindingsThe analysis revealed that coaches drew on factors from school and classroom contexts of professional development practice and from collective beliefs about effective practice, alongside the project materials incorporated in the design of the project. System-level stories of reading reform influenced coaches' leadership of professional practice in implementing the New Zealand Numeracy Development Project, a progressively scaled-up professional learning and development initiative designed to improve teacher knowledge and pedagogy.Originality/valueThis paper highlights the critical importance of coaches' knowledge and expertise, the complexity of the implementation process and the coherence of the infrastructure that supports them in instructional reform.
Financial expert CEOs, political intervention, and corporate investment decisions: evidence from the anti-corruption campaign
Authors: Anderson Hamish D. , Liao Jing , Yue Shuai 
Published: August 2021

PurposeEmploying the anti-corruption campaign as an exogenous political shock, this paper examines how political intervention shapes the impact of financial expert CEOs on firm investment decisions.Design/methodology/approachThis paper uses a sample of 2,808 Chinese firms listed in the Shanghai and Shenzhen Stock Exchanges from 2003 to 2016. Panel data is used for conducting the analysis controlling for firm, industry, and year fixed effects.FindingsThe authors found that CEOs with financial expertise are sensitive to political intervention when making investment decisions. First, financial expert CEOs spend more on R&D expenditure in private-owned companies and they are associated with less R&D expenditure in state-owned enterprises (SOEs). Second, financial expert CEOs are associated with higher investment expenditure in general, but they become less likely to invest more in the post-anti-corruption period. The reduction in investment expenditure due to the anti-corruption campaign is more pronounced in SOEs than in private-owned companies. Third, the anti-corruption campaign promotes R&D investment in general, but in SOEs, expert CEOs tend to be less likely to invest more on R&D after the anti-corruption shock.Originality/valueThis paper enriches the growing literature on the impact of political intervention and the role of the anti-corruption campaign on corporate behaviour.
Evaluating interaction between internal hospital supply chain performance indicators: a rough-DEMATEL-based approach
Authors: Soto Lopez Daniel , Garshasbi Maryam , Kabir Golam , Bari A.B.M. Mainul , Ali Syed Mithun 
Published: August 2021

PurposePrevious studies on hospital supply chain performance have attempted to measure the performance of the hospital supply chain either by the measurement of performance indicators or the performance of specific activities. This paper attempts to measure the internal hospital supply chain's performance indicators to find their interdependencies to understand the relationship among them and identify the key performance indicators for each of those aspects of the logistics process toward improvement.Design/methodology/approachIn this research, a systematic assessment and analysis method under vagueness is proposed to assess, analyze and measure the internal health care performance aspects (HCPA). The proposed method combines the group Decision-Making and Trial Evaluation Laboratory (DEMATEL) method and rough set theory.FindingsThe study results indicate that the most critical aspects of hospital supply chain performance are completeness of treatment, clinical care process time and no delay in treatment.Originality/valueThe causal relationship from rough-DEMATEL can advise management officials that to improve the completeness of treatment toward patient safety, clinical care process time should be addressed initially and with it, patient safety aspects such as free from error, clinical care productivity, etc. should be improved as well. Improvement of these aspects will improve the other aspects they are related to.

Older adults in virtual communities: understanding the antecedents of knowledge contribution and knowledge seeking through the lens of socioemotional selectivity and social cognitive theories
Authors: Zhou Junjie , Kishore Rajiv , Zuo Meiyun , Liao Ruochen , Tang Xiao 
Published: August 2021

Purpose
As older adults are increasingly active in virtual communities (VCs), these platforms for knowledge exchange present opportunities for companies to use elder human capital. The purpose of this study is to understand the antecedent factors that motivate older adults’ knowledge contribution and knowledge seeking (KS) behaviors in VCs.

Design/methodology/approach
Rooted in socio-emotional selectivity and social cognitive theories, this study included five key variables and developed models for older adults’ knowledge contributing (KC)/KS behaviors. This paper tested the hypotheses using data from a sample of 204 older adults in 3 VCs in China.

Findings
The results provide support for most of the hypotheses and show that while other members’ participation (MP) acts as a substitute for meaning in life and attitude toward aging, it acts as a complement for outcome expectations (OE) focused on others and OE focused on oneself in their impacts on KC/KS activities.

Practical implications
The study provides practical insights for developing elder human resources via VCs to avoid knowledge loss.

Originality/value
This study described older adults’ unique characteristics when modeling their information and communication technologies-related behaviors and built two models to explain their KC/KS behaviors. It confirmed that the same factor has different levels of impact on older adults’ KC/KS behaviors in VCs. In addition, it confirmed and reinforced the complementary and substitutive effects of other MP as an environmental factor on these behaviors.
