Published: July 2018

AbstractRepresentatives of helping professions are particularly exposed to occupational stress. The aim of the study was to evaluate mental and physical well-being, as well as their correlates and predictors in a group of employees working at youth educational centres and sociotherapy centres. A total of 96 employees working at youth educational centres and sociotherapy centres in Kujawsko-Pomorskie voivodeship took part in the study. The following psychometric tools were used: the Psychosocial Working Conditions Questionnaire, the Mini-COPE, the LOT-R, and the GSES. The results obtained indicate that people working in helping professions experience mental and physical health problems. Only 3% of the subjects declared they sleep all night. Over 40% and over 35% of the subjects estimate they suffer from low mood and irritation episodes, respectively, rather frequently or continually. Subjects with poorer mental health are more likely to use Helplessness, Avoidance behaviours, or Turning to religion to cope with stress. The strongest predictor of mental well-being is the sense of self-efficacy. Whereas, the strongest predictor of physical well-being is the ability to cope with stress by giving into the feeling of Helplessness. The study demonstrated poor mental and physical well-being of the subjects. A statistically significant correlation was found between sex and the level of mental and physical health. Employees working at youth educational centres and sociotherapy centres with better mental and physical well-being had a stronger sense of self-efficacy and a higher level of life optimism. Hence, the sense of self-efficacy is a predictor for better mental well-being.

AbstractThe AbsA1-AbsA2 two component signalling system ofStreptomyces coelicolorhas long been known to exert a powerful negative influence on the production of the antibiotics actinorhodin, undecylprodiginine and the Calcium-Dependent Antibiotic (CDA). Here we report the analysis of aΔabsA2deletion strain, which exhibits the classic precocious antibiotic hyper-production phenotype, and its complementation by an N-terminal triple-FLAG-tagged version of AbsA2. The complemented and non-complementedΔabsA2mutant strains were used in large-scale microarray-based time-course experiments to investigate the effect of deletingabsA2on gene expression and to identify thein vivoAbsA2 DNA-binding target sites using ChIP-on chip. We show that in addition to binding to the promoter regions ofredZandactII-orfIVAbsA2 binds to several previously unidentified sites within thecdabiosynthetic gene cluster within and/or upstream ofSCO3215-SCO3216,SCO3217,SCO3229-SCO3230, andSCO3226, and we relate the pattern of AbsA2 binding to the results of the transcriptomic study and antibiotic phenotypic assays. Interestingly, dual ‘biphasic’ ChIP peaks were observed with AbsA2 binding across the regulatory genesactII-orfIVandredZand theabsA2gene itself, while more conventional single promoter-proximal peaks were seen at the CDA biosynthetic genes suggesting a different mechanism of regulation of the former loci. Taken together the results shed light on the complex mechanism of regulation of antibiotic biosynthesis inStreptomyces coelicolorand the important role of AbsA2 in controlling the expression of three antibiotic biosynthetic gene clusters.
Lesson study as a fundamental situation for the knowledge of teaching
Authors: Clivaz Stéphane 
Published: July 2018

Purpose
The purpose of this paper is to elaborate on the commonality between the Theory of Didactical Situations (TDS) and lesson study to propose a model of lesson study using both the predominant graphical representation of lesson study by Lewis and the model of the didactical situation at the heart of TDS by Brousseau.

Design/methodology/approach
Starting by describing and adapting the predominant graphical representation of lesson study by Lewis and the model of the didactical situation at the heart of TDS by Brousseau, the paper integrates the two representations to highlight the commonalities between the students’ learning situation and the teachers’. Based on this integrated graphical representation, the key phases of lesson study are then conceptualised by the mean of the dialectic between didactical and adidactical situation.

Findings
The reflection about the use of the TDS graphical representation embedded in the lesson study diagram helps the reflection on the use of TDS itself to analyse lesson study. This theoretical analysis describes the process of teacher learning in lesson study and the link between their learning and the student’s. It also shows that lesson study is a good candidate for the fundamental situation of the knowledge for teaching.

Originality/value
The graphical conceptualisation of lesson study as a learning situation for teachers offers new insight about how teachers learn in lesson study.
Effect of the size on the friction characteristics of brake friction materials: a case study with Al2O3
Authors: Sugözü Banu , Dağhan Behcet , Akdemir Ahmet 
Published: July 2018

Purpose
The purpose of this paper is to study the potential of alumina (Al2O3) in nanometer size in automotive brake friction materials.

Design/methodology/approach
Four brake linings containing alumina differing in particle size (355 µm and 80 nm) and various amount (5 and 10 Wt.%) were designed and produced. The hardness, density and porosity of the samples were measured. All samples were tested on a full-scale brake dynamometer with gray cast iron disc to determine the tribological properties. Detailed examinations on the worn surface were analyzed using a scanning electron microscopy.

Findings
It was concluded that all performance parameters were beneficially affected because of nano alumina.

Originality/value
This paper emphasizes the importance of nano-composites in the automotive industry and helps industrial firms and academicians working on wear of materials.
Constructing authority in times of crisis
Authors: Zhao Hui 
Published: July 2018

PurposeThe purpose of this paper is to investigate how the Chinese government generates authority during a crisis through discursive practices expressed in social media.Design/methodology/approachUsing the theoretical framework of authority and the method of genre analysis, this study examined the top 100 forwarded posts on Weibo about a high-profile murder to determine the mechanisms involved in generating authority.FindingsThis study provides empirical support that building and maintaining authority distinguishes governments from other social actors during crisis communication. The genre analysis demonstrates that the strategic use of genre chain and genre mixing contributes to the construction of governments’ authority during a crisis. Furthermore, this study suggests the performative and social constructionist approach to understand governments’ authority in the digital age on two levels: a situationally-constructed concept that goes beyond the context of fixed institutions and a relationally-constructed concept that is promoted through discursive collaboration among various social actors.Research limitations/implicationsThis study does not directly assess the effectiveness of a government’s ability to construct its authority. Nor does it examine the construction of governments’ authority outside the context of an authoritarian regime. These issues should be addressed in future research.Practical implicationsThis study offers governmental organizations some practical insights that can be used to infuse a constructive aspect of authority into their crisis communication plans, practices and processes.Originality/valueHere, authority is seen as a social construction that foregrounds the discursive, performative, constructive and communicative dimensions of crisis communication. Moreover, this study points to the need for a more complex integrated perspective in crisis communication that includes and connects corporate and government crisis communication.

Authors: Celuch Kevin , Bourdeau Bryan , Khayum Mohammed , Townsend Leslie 
Published: July 2018

Purpose
The purpose of this paper is to present an adaptation of a program that is at the intersection of two dynamic force fields. The first relates to imperatives impinging upon and inherent in higher education. The second ties to the concept of ecosystems as spaces for aligning actors and resources to create value.

Design/methodology/approach
Tables I-III present pre-test and post-test means and p-values for the paired sample t-tests for the measures.

Findings
As expected, post-test means are consistently significantly higher (or lower depending on item wording) for a shift in beliefs away from self-censoring and prejudging ideas during ideation and more toward greater openness in the ideation process.

Originality/value
The paper examines the outcome of an educational program.
Critical success factors for sustainable construction: a literature review
Authors: Sfakianaki Eleni 
Published: July 2018

Purpose
The purpose of this paper is to synthesize and evaluate the available literature with respect to critical success factors (CSFs) for sustainable construction (SC).

Design/methodology/approach
A systematic literature review (SLR) was undertaken to assist in the identification of the most pertinent papers from three publishers: Emerald, Elsevier and Wiley. The literature findings were assessed and presented relative to publication, author and contents as determined by review.

Findings
The SLR was conducted using a number of search criteria. A final set of 31 publications were detected for further examination. The characteristics in terms of publications, authors and contents of the extracted publication set were examined and discussed. A total of 35 factors were identified, distributed in five research categories. The frequency of the extracted factors within the publication set was investigated and enabled valuable quantitative and qualitative observations of current trends for SC. Interestingly, all research categories were represented in the top-counted factors, demonstrating a holistic perception of SC. Given the publication set, in most aspects, the research area examined seems to demonstrate features of an emerging field, which is not yet well established.

Research limitations/implications
SLR cannot ensure that all pertinent publications were identified, because it was tailored to a number of search criteria, although certain actions were taken to moderate this limitation. However, the outcome adequately identifies trends and offers valuable information and knowledge for SC and its successful implementation.

Originality/value
The present study presents a broad list of factors for SC, integrated from a variety of disciplines and stakeholders. The findings, therefore, provide a valuable reference for both construction professionals and practitioners attempting to implement SC. Furthermore, the list can be of use to academic scholars for further empirical work and basis for future research.
Evaluating the impact of police foot patrol at the micro-geographic level
Authors: Andresen Martin A. , Hodgkinson Tarah K. 
Published: July 2018

PurposeThe purpose of this paper is to investigate the impact of a police foot patrol considering micro-geographic units of analysis.Design/methodology/approachSix years of monthly crime counts for eight violent and property crime types are analyzed. Negative binomial and binary logistic regressions were used to evaluate the impact of the police foot patrol.FindingsThe impact of police foot patrol is in a small number of micro-geographic areas. Specifically, only 5 percent of the spatial units of analysis exhibit a statistically significant impact from the foot patrol.Originality/valueThese analyses show the importance of undertaking evaluations at the micro-scale in order to identify the impact of police patrol initiative because a small number of places are driving the overall result. Moreover, care must be taken with how small the units of analysis are because as the units of analysis become smaller and smaller, criminal events become rarer and, potentially, identifying statistically significant change becomes more difficult.
The impact of the police professional identity on burnout
Authors: Schaible Lonnie M. 
Published: July 2018

Purpose
Little research has been conducted which assesses the impact of the police self-identity on burnout. The purpose of this paper is to assess how identification with the police role, work centrality, policing values and perceived dissonance in values contributes to emotional exhaustion across the police career.

Design/methodology/approach
Conjunctive analysis of case configurations (CACC) is utilized to examine how various factors conjunctively interact to influence the probability of burnout among officers at various career stages. This method allows for the examination of more complex interactions than traditional statistical methods.

Findings
The findings suggest that the interaction between police values and professional identity is complex and neither completely supportive nor unsupportive of existing identity theories. Specifically, strong identification with the police role has both positive and negative effects over the course of the police career.

Practical implications
Understanding how the police professional identity changes over the course of the police career can help to inform more deliberate and targeted training to help officers avoid burnout and improve the quality of policing for both citizens and police.

Originality/value
The present research applies an emerging statistical method, CACC, to an important but understudied question – the impact of the police professional identity on burnout throughout the career. In doing so, the present research illustrates that the effects of the professional identity on burnout are both complex, with significant ramifications for the practice of policing.
Beyond the final report
Authors: Terrill William , Paoline III Eugene A. , Ingram Jason Robert 
Published: July 2018

Purpose
The purpose of this paper is to provide a snapshot of key findings from research published from the Assessing Police Use of Force Policy and Outcomes study, a project funded by the National Institute of Justice.

Design/methodology/approach
Key findings from a national survey of police agencies on use of force policy and from an in-depth look at police use of force outcomes across eight cities published over the last ten years are synthesized to provide a cumulative perspective regarding the outcomes of the project.

Findings
The majority of police departments had a written force policy and reporting requirements, however, there was no commonly accepted force policy. Patrol officers were conservative in their views of what is reasonable force, administrative policy does matter in influencing force usage, and the use of a TASER impacted the likelihood of injury for both officers and citizens. Additional findings were also reviewed in the areas of complaints, police culture, first-line supervision, college education, and promotional aspirations.

Originality/value
While federal funding for policing related research projects are commonplace, taking a look back ten years later and summarizing key findings is uncommon. Doing so provides concise feedback to practitioners in one readily digestible manuscript. Furthermore, the paper also demonstrates the additional value to the original investment made by the National Institute of Justice.

Authors: Vaughan Adam , Wuschke Kathryn E. , Hewitt Ashley N. , Hodgkinson Tarah , Andresen Martin A. , Brantingham Patricia , Verdun-Jones Simon 
Published: July 2018

PurposeInvestigating the day of week and hour of day temporal patterns of crime typically show that (late) nights and weekends are the prime time for criminal activity. Though instructive, mental-health-related calls for service are a significant component of police service to the community that have not been a part of this research. The purpose of this paper is to analyze calls for police service that relate to mental health, using intimate partner/domestic related calls for police service for context.Design/methodology/approachApproximately 20,000 mental health related and 20,000 intimate partner/domestic related calls for police service are analyzed. Intra-week and intra-day temporal patterns are analyzed using circular statistics.FindingsMental-health-related calls for police service have a distinct temporal pattern for both days of the week and hours of the day. Specifically, these calls for police service peak during the middle of the week and in the mid-afternoon.Originality/valueThis is the first analysis regarding the temporal patterns of police calls for service for mental health-related calls. The results have implications for police resourcing and scheduling, especially in the context of special teams for addressing mental health-related calls for police service.
Offender and family member perceptions after an offender-focused hot spots policing strategy
Authors: Santos Roberto G. 
Published: July 2018

PurposeThe purpose of this paper is to examine how both offenders and their families perceived their interactions with police and whether there were negative consequences of the offender-focused strategy that was implemented in a hot spots policing experiment.Design/methodology/approachData from interviews of 32 offenders and 29 family members are examined qualitatively for themes to evaluate how the strategy was carried out and how it impacted offenders’ behavior and both groups’ perceptions of the police detectives and the strategy overall.FindingsThe results show that there was overwhelming agreement by both offenders and their family members that the police detectives who contacted them treated both groups with dignity and respect. After the contact was over, the offenders appeared to commit less crime, followed probation more closely, and had positive feelings about what the police detectives were trying to do. Improvement of the offenders’ relationships with their families was an unanticipated finding indicating a diffusion of benefits of the strategy.Practical implicationsThe results suggest that when procedural justice principles are used in an offender-focused police intervention, positive impact can be achieved without negative consequences.Originality/valueThis is a rare example of an in-depth evaluation of the perceptions of offenders and family members contacted through a hot spots policing offender-focused strategy.

Modeling satisfaction and repurchase intentions of mobile smart wristbands: the role of social mindfulness and perceived value
Authors: Oyedele Adesegun , Saldivar Roberto , Hernandez Monica D. , Goenner Emily 
Published: July 2018

Purpose
This paper aims to empirically test a model of different facets of perceived value (economic, emotional, aesthetic and convenience) and social mindfulness (SM) as determinants of consumer satisfaction and repurchase intentions of mobile smart wristbands.

Design/methodology/approach
A questionnaire designed to assess these effects was administered to students at a Midwestern US university. Data were analyzed using AMOS structural equation modeling software.

Findings
The findings reveal that SM was significant in explicating perceived convenience value. The utilitarian value measures in the model (economic and convenience) were found to significantly affect satisfaction and in turn, repurchase intention. Surprisingly, all hedonic-related constructs in the model (emotional and aesthetic) did not significantly affect satisfaction and subsequently, repurchase intentions.

Practical implications
Findings from this research suggest that when targeting young adults, marketing managers and retailers should focus their efforts to convenience value as influenced by SM.

Originality/value
This is one of only a few studies in marketing to investigate the role of SM and perceived value on satisfaction and repurchase intentions of a technology gadget among young consumers.
Widespread nitrogen fixation in sediments from diverse deep‐sea sites of elevated carbon loading

SummaryNitrogen fixation, the biological conversion of N2 to NH3, is critical to alleviating nitrogen limitation in many marine ecosystems. To date, few measurements exist of N2 fixation in deep‐sea sediments. Here, we conducted > 400 bottle incubations with sediments from methane seeps, whale falls and background sites off the western coast of the United States from 600 to 2893 m water depth to investigate the potential rates, spatial distribution and biological mediators of benthic N2 fixation. We found that N2 fixation was widespread, yet heterogeneously distributed with sediment depth at all sites. In some locations, rates exceeded previous measurements by > 10×, and provided up to 30% of the community anabolic growth requirement for nitrogen. Diazotrophic activity appeared to be inhibited by pore water ammonium: N2 fixation was only observed if incubation ammonium concentrations were ≤ 25 μM, and experimental additions of ammonium reduced diazotrophy. In seep sediments, N2 fixation was dependent on CH4 and coincident with sulphate reduction, consistent with previous work showing diazotrophy by microorganisms mediating sulphate‐coupled methane oxidation. However, the pattern of diazotrophy was different in whale‐fall and associated reference sediments, where it was largely unaffected by CH4, suggesting catabolically different diazotrophs at these sites.
