High suicide rates among men presents a global challenge for commissioners and clinicians. Innovative approaches towards suicide prevention interventions designed for men are needed. The James’ Place (JP) service opened in 2018, and its model of practice is a clinical, community-based intervention for men experiencing suicidal crisis. This paper aims to describe the implementation framework within which the JP model is applied.

Fostering a public health case study approach, this paper provides a description of how the JP service operates, including the referral pathways, key components of this innovative model and its impact upon the men who receive the intervention. Illustrative case studies derived from semi-structured interviews from men and therapists are reported.

The JP model is dynamic and flexible, allowing the tailoring of a suicidal crisis intervention to suit the needs and priorities of the individual and the wider local community. Clinical and practical implications, such as reduction in suicidality, are discussed.

Rapidly accessible, effective community-based interventions for men experiencing suicidal crisis are required. Yet, while widely advocated in policy, there remains a dearth of evidence illustrating the real-world application and value of such services within a community-setting. To the best of the authors’ knowledge, the JP model is the first of its kind in the UK and an example of an innovative clinical, community-based suicide prevention intervention offering support for men experiencing suicidal crisis.

Attempts are made to utilize the aqueous extracts of natural compounds, namely cordia latifolia and curcumin, as corrosion inhibitors for mild steel in cooling systems, and their inhibition efficiencies are compared with that of Hydroxyethylidene 1‐1 diphosphonic acid (HEDP). HEDP is also blended with aqueous extracts of natural compounds so as to improve their inhibition efficiency. The blowdown of the cooling system is also analysed for environmental factors.

Current conceptualisations of strategic flexibility and its antecedents are theory‐driven, which has resulted in a lack of consensus. To summarise this domain the paper aims to develop and present an a priori conceptual model of the antecedents and outcomes of strategic flexibility. Discussion and insights into the conceptual model, and the relationships specified, are made through a novel qualitative empirical approach. The implications for further research and a framework for further theoretical development are presented.

An exploratory qualitative research design is used applying multiple data collection techniques in a branch network of a large regional retailer in the UK. The development of strategic options and the complex relationship to strategic flexibility is investigated.

The number and type of strategic options developed by managers impact on the degree of strategic flexibility and also on the ability of the firm to achieve competitive differentiation. Additionally, the type of strategic option implemented by managers is dependent on the competitive situation faced at a local level. Evidence of managers' limited perception of competition was identified based on their spatial embeddedness.

A single, in‐depth case study was used. The data gathered is rich and appropriate for the exploratory approach adopted here. However, generalisability of the findings is limited.

Strategic flexibility is rooted in the ability of front‐line mangers to develop and implement strategic options; this in turn facilitates competitive differentiation.

The research presented is unique in this domain on two accounts. First, theory is developed by presenting an a priori conceptual model, and testing through in‐depth qualitative data gathering. Second, insights into strategic flexibility are presented through an examination of managerial cognition, resources and strategic option generation using cognitive mapping and laddering technique.

Increased ethanol accumulation during ethanol fermentation generates stress in yeast cells, which finally reduces the fermentation performance and efficiency. Trehalose, a potential stress protectant, has been reported to regulate the response of yeast to diverse environmental stresses. This study aimed to explore how exogenous trehalose application affects the survival, transcriptome and antioxidant enzymes of Wickerhamomyces anomalus grown under ethanol stress conditions.

Exogenous trehalose was applied to the growth condition of W. anomalus, and optical densitometric method was used to detect contents of intracellular trehalose and MDA and activities of CAT and SOD. The survival was evaluated using spot analysis. Differentially expressed genes (DEGs) were identified through transcriptomics analysis.

The results showed that ethanol stress induced the accumulation of intracellular trehalose, with further exogenous trehalose application improving the survival and alleviating oxidative stress in ethanol-stressed W. anomalus. Transcriptomic results showed that trehalose has pleiotropic regulating effects on ethanol-stressed W. anomalus since most DEGs annotated to energy metabolism, amino acid metabolism, translation, folding, sorting and transport were affected post trehalose addition. Therefore, it is found that trehalose protected W. anomalus against ethanol stress, and these findings provide interesting insights into the mechanistic role of trehalose in improving ethanol stress tolerance of W. anomalus.

(1) Protective effect of exogenous trehalose addition on the survival of ethanol-stressed W. anomalus was proved. (2) Exogenous trehalose addition could partly alleviate oxidative stress induced by ethanol stress and affect transcriptome in W. anomalus.

This paper aims at exploring the factors that are important for the digital development of small and medium-sized enterprises (SMEs) in response to the coronavirus disease 2019 (COVID-19) crisis compared to large-sized enterprises.

Using data from a survey in Greek firms during the pandemic, econometric models are estimated to identify factors that are related to the expansion of digital marketing and e-commerce practices of SMEs and large-sized enterprises based on the technology–organization–environment framework.

The results suggest that while further investments in information and communication technology (ICT) infrastructure are important for the digital development of SMEs during the COVID-19 crisis, it is the innovative activities that advance the digitalization of large-sized enterprises. Also, SMEs, which implement flexible human resource (HR) practices (such as remote work) and face delays in the supply chain due to the pandemic, appear to have increased probability of expanding their digital marketing and e-commerce. On the contrary, HR practices do not seem to matter for large firms, while new regulations appear to discourage their digital development during the COVID-19 crisis.

This is the first study which empirically explores the digital reactions of SMEs compared to those of large-sized enterprises in a pandemic crisis context. It advances the limited knowledge on the potentially different responses of SMEs and large-sized enterprises to major external shocks with respect to their digital marketing and e-commerce expansion.

The inhibition effects of sodium silicate and polyphosphate on corrosion of carbon steel in a potable water supply have been studied using weight loss, electrochemical impedance and Tafel polarization measurements. In the water supply under test there were sufficient calcium ions, (220 ppm), to form the normal polyphosphates salts, which is a requisite for good protection. It was concluded that the inhibition efficiency of polyphosphate was higher than that of silicate. The synergistic inhibition effects of polyphosphate on the inhibition of silicate were studied. The results illustrated that silicates and polyphosphates can be useful as corrosion inhibitors for reducing the corrosion of carbon steel in potable water supply distribution systems. The optimal concentration for silicate alone was determined to be 11 ppm and for polyphosphate alone was 8 ppm. The optimum ratio of concentration for sodium silicate to sodium polyphosphate was 4 : 3.

In this study, the effects of using corrugated absorber plate (instead of flat plate) and also using aerosol/carbon-black nanofluid (instead of air) on heat transfer and turbulent flow characteristics in solar collectors were numerically investigated.

The 3D continuity, momentum and energy equation were solved by finite volume and SIMPLE algorithm. As a result, the corrugated absorber plate was inspected in the case of triangle, rectangle and sinuous with the wave length of 1 mm and wave amplitude of 3 mm in turbulent flow regime and Reynolds number between 2,500 and 4,000. Choosing the proper geometry was carried out based on the best performance evaluation criteria (PEC) and increasing the air temperature from collector inlet to outlet.

The results revealed that for all times of the year the highest PEC was obtained for corrugated Sinusoidal model; however, the highest temperature increase from inlet to outlet was obtained for rectangular corrugated model. In addition, the results indicated that in sinusoidal model, the nanoparticles volume fractions increase leads to heat performance coefficient increase and the best heat performance conditions were attained in volume fraction of 0.1 per cent and Reynolds number of 4,000 for both six months period. In model with rectangular corrugated plate, usage of nanofluid in all range of Reynolds numbers leads to reduction of outlet temperature.

The effect of some nanoparticles on heat transfer using thermal– hydraulic performances in heat exchangers has been assessed, but the effects of atmospheric aerosol-based nanofluid using carbon-black nanoparticles (CBNPs) on the heat transfer in corrugated heat sink solar collectors by 3D numerical modeling has not been yet investigated. In present study, usage of CBNPs with different volume fractions in range of 0 to 0.1 per cent in turbulent regime of fluid flow is analyzed. Furthermore, in this paper, besides the effects of using CBNPs, a solar absorber located in Shiraz, as one of the best solar irradiation receiver cities in Iran is evaluated.

The purpose of this paper is to outline the articles presented in the Special Issue on the topic of “Marketing and flexibility”, and to discuss key issues associated with major debates relating to flexibility in order to position the articles within a wider context and highlight some key issues for further research.

Themes in prior research relating to “Marketing and flexibility” are documented and the growth of research interest into strategic flexibility is tabulated. The contributions of each article are briefly discussed.

There has been a steady growth of research interest into flexibility. To provide an example of this growth, the increase in the number of articles published on the topic of strategic flexibility in scholarly journals is highlighted over a 20‐year period. Key issues in prior research such as alternative definitions and the different postulated relationships between market orientation and strategic flexibility are revealed, as are issues for future research.

Key issues relating to research into flexibility for marketing scholars are revealed.

The purpose of this paper is to present taxonomy of marketing strategy concepts and integrative frameworks that differentiate and integrate its formulation and implementation processes.

The paper is conceptual based on a review of academic literature on marketing strategy chronicled in major marketing journals January 1990‐April 2006. We present selected references classified by key marketing strategy topics for further pursuit by interested readers. Also, the paper reflects our experience and views based on practices chronicled in corporate case studies and trade journals.

The literature casts marketing strategy formulation and implementation in the context of strategic planning and marketing strategy process models. The focus of the strategic planning model is on achieving corporate financial objectives through the implementation of product, pricing, promotion, and place (distribution) programs. The focus of the marketing strategy process model is on the formulation of segmentation, targeting, differentiation, and positioning strategies to create, communicate, and deliver the value to the customer resulting in gaining customer satisfaction and loyalty; i.e. marketing objectives.

The propositions and frameworks constitute guidelines useful in the process of marketing strategy formulations and implementation by practitioners and establish bases for academic researchers to test concept validity, examine concept differences, and explore concept relationships.

This paper advances propositions that clearly differentiate, but interrelate, marketing strategy formulation and implementation processes and recast the strategic planning financial‐oriented model and the marketing strategy process models into a set of frameworks to demonstrate that: the road to healthy financial results must first be paved by sound marketing strategies; explicitly state and underscore the role of branding and organizational strategies in mediating formulated marketing strategy into actionable marketing programs; and broaden the concept of firm orientation to reflect its role in mediating corporate strategy into a set of functional strategies including marketing.
