AbstractThe 35 kDa water-soluble Orange Carotenoid Protein (OCP) is responsible for photoprotection in cyanobacteria. It acts as a light intensity sensor that simultaneously serves as efficient quencher of phycobilisome excitation energy as well as of reactive oxygen species. Photoactivation triggers large-scale conformational rearrangements to convert OCP from the orange OCPOstate to the red active signaling state OCPR, as demonstrated by various structural methods. Eventually, such rearrangements imply complete yet reversible separation of structural domains (C- and N-terminal domain) and significant translocation of the carotenoid cofactor. Very recently, dynamic crystallography of OCPOcrystals suggested the existence of photocycle intermediates with small-scale rearrangements that may trigger further transitions in the protein. However, the currently existing gap between the ultra-fast picosecond and 100 millisecond time scale of spectroscopic and structural data precludes knowledge about distinct intermediate states. In this study, we took advantage of single 7 ns laser pulses to study carotenoid absorption transients in OCP on the time-scale from 100 ns to 10 s, which allowed us to detect a red intermediate state preceding the red signaling state OCPR. In addition, time-resolved fluorescence spectroscopy and following assignment of carotenoid-induced quenching of different tryptophan residues revealed a novel orange intermediate state, which appears during back-relaxation of photoactivated OCPRto OCPO. Our results show asynchronous changes in the carotenoid and protein components and provide refined mechanistic information about the OCP photocycle as well as introduce new kinetic signatures for future studies of OCP photoactivity and photoprotection.Significance statementCyanobacteria utilize the Orange Carotenoid Protein (OCP) to protect their photosynthetic apparatus from the harmful effects of intense sunlight. OCP is a blue light-triggered photoswitch, which undergoes photoconversion from its dark adapted orange to the active red state, the latter being able to interact with the phycobilisome antennae and quench their fluorescence, thus avoiding excessive energy flow to the photosystems. With the help of the fluorescence recovery protein (FRP), OCP detaches from phycobilisomes and can return faster into the orange state. Until now, only the thermodynamically stable orange state and the metastable red state are established in a primitive photocycle. In this work, we apply transient absorption and fluorescence spectroscopy and identify two novel photocycle intermediates of physiological relevance.
Towards a highly efficient diversity census of the prokaryotic biosphere: a group testing approach
Authors: Shalem Bar , Amir Amnon , Porat Ely , Shental Noam 
Published: July 2017

AbstractExploring the microbial biosphere has grown exponentially in recent years, although we are far from understanding its entirety. We present the âdiversity censusâ problem of exploring all bacterial species in a large cohort of specimens, and detecting a specimen that contains each species. The naive approach to this problem is to sequence each specimen, thus requiring costly sample preparation steps.We suggest an orders of magnitude more efficient approach for diversity censusing. Specimens are pooled according to a predefined design and standard 16S rRNA sequencing is performed over each pool. For each bacterial species, from the ultra-rare to the most common, the algorithm detects a single specimen that contains the bacterial species. The approach can be applied to large cohorts of monomicrobial cultures or to complex samples containing a mixture of organisms.We model the experimental procedure and show viain silicosimulations that the approach enables censusing more than 95% of the species while taking 10 – 70 fold less resources. Simulating experiments using real samples display the utility in censusing large cohorts of samples.Diversity censusing presents a novel problem in the mathematical field of group testing that may also be applied in other biological problems and in other domains.
Paleo-oscillomics: inferring aspects of Neanderthal language abilities from gene regulation of neural oscillations
Authors: Murphy Elliot , Benítez-Burraco Antonio 
Published: July 2017

AbstractLanguage seemingly evolved from changes in brain anatomy and wiring. We argue that language evolution can be better understood if particular changes in phasal and cross-frequency coupling properties of neural oscillations, resulting in core features of language, are considered. Because we cannot track the oscillatory activity of the brain from extinct hominins, we used our current understanding of the language oscillogenome (that is, the set of genes responsible for basic aspects of the oscillatory activity relevant for language) to infer some properties of the Neanderthal oscillome. We have found that several candidates for the language oscillogenome show differences in their methylation patterns between Neanderthals and humans. We argue that differences in their expression levels could be informative of differences in cognitive functions important for language.
Time wasting behaviour: how to identify and address it as the team leader
Authors: McLachlan John , Meager Karen 
Published: July 2017

Purpose
The purpose of this paper is to help leaders and managers understand what is going on behind time-wasting behaviors they see in their teams and support them in making productive changes.

Design/methodology/approach
Taken from Time Mastery: Banish Time Management Forever by Karen Meager and John McLachlan. This study uses an integrative psychology approach drawing on modalities such as transactional analysis, neuro-linguistic programming (NLP), cognitive behavioral theory (CBT) and traditional leadership models, and integrating those with the authors’ practical experience working in organizations over the past 15 years.

Findings
Team members’ time management issues can be addressed if leaders take a more holistic view of their behavior. Traditional time management approaches do not work for everyone, so leaders need to tailor their style to adapt. There are some common time-wasting behaviors that are easily addressed, once identified.

Originality/value
Taken from the newly published Time Mastery: Banish Time Management Forever by Karen Meager and John McLachlan, this study combines the psychology of how we process, communicate, and use time from a number of psychological methodologies and combines them with practical organizational case studies and experience.
Modern prejudice and strength of conjunction error
Authors: Wolfram Hans-Joachim 
Published: July 2017

Purpose
Modern prejudice was examined as a potential predictor of overestimating proportions of minority employees in gender-typed occupations. Strength of conjunction error was considered as an indicator of distorted perceptions of these proportions. Furthermore, the purpose of this paper is to investigate whether the association between modern prejudice and strength of conjunction error was weaker for gender-untypical than for gender-typical targets.

Design/methodology/approach
Modern prejudice was considered as a predictor of overestimations of black female employees in Study 1 (n=183) and black female older employees in Study 2 (n=409). Data were collected using internet-mediated questionnaires.

Findings
In Study 1, modern racism, but not modern sexism, was associated with greater strength of conjunction error when respondents were presented with gender-typical targets. In Study 2, using a sample scoring higher on modern prejudice than in Study 1, modern racism, but not modern sexism and modern ageism, was associated with greater strength of conjunction error, irrespective of target occupation. Furthermore, there was an unexpected association between lower sexism and greater strength of conjunction error for gender-typical targets, but not for gender-untypical targets.

Research limitations/implications
The findings lend support to the ethnic-prominence hypothesis in that modern racism, but not modern sexism or modern ageism, was associated with greater strength of conjunction error. Furthermore, empirical evidence suggests that target non-prototypicality can dilute the effect of modern prejudice on strength of conjunction error.

Originality/value
This is one of the rare studies examining attitudes and conjunction error in a work-relevant context, thereby bridging the gap between social cognition and applied psychology.
Women leadership barriers in healthcare, academia and business
Authors: Kalaitzi Stavroula , Czabanowska Katarzyna , Fowler-Davis Sally , Brand Helmut 
Published: July 2017

Purpose
The purpose of this paper is to map the barriers to women leadership across healthcare, academia and business, and identify barriers prevalence across sectors. A barriers thematic map, with quantitative logic, and a prevalence chart have been developed, with the aim to uncover inequalities and provide orientation to develop inclusion and equal opportunity strategies within different work environments.

Design/methodology/approach
A systematic literature review method was adopted across five electronic databases. Rigorous inclusion/exclusion criteria were applied to select relevant publications, followed by critical appraisal of the eligible articles. The geographical target was Europe, with a publication time range spanning the period from 2000 to 2015. Certain specialized international studies were also examined. The key themes were identified using summative content analysis and the findings were analyzed using qualitative meta-summary method to formulate hypotheses for subsequent research.

Findings
In total, 26 barriers were identified across the aforementioned sectors. A high degree of barriers commonalities was identified, with some striking differences between the prevalence of barriers across sectors.

Research limitations/implications
The results of this study may need further validation using statistical methodology given the knowledge base gaps regarding the range of barriers and the differences in their prevalence. Bias and interpretation in reporting anchored in different theoretical frameworks ought to be further examined. Additional variables such as ambiguously stated barriers, sector overlap, women’s own choices, cultural and educational background and analysis in the context of the economic crisis, ensuing austerity and migratory pressure, are also worth exploring.

Practical implications
Women’s notable and persisting underrepresentation in top leading positions across sectors reflects a critical drawback in terms of organizational and societal progress particularly regarding inclusion and balanced decision making. Practice-related blind spots may need to be further examined and addressed through specific policies.

Originality/value
The comparative nature of barriers to women leadership across three sectors allows the reader to contrast the differences in gender inequalities and to comprehend inclusion challenges in healthcare, academia and business. The authors draw attention to varying degrees of barriers prevalence that have been understudied and deserve to be further explored. This gap in knowledge extends to policy, thus, highlighting the need to address the gender equality and inclusion challenges in a context-specific manner across work environments.
How French managers picture their careers: a gendered perspective
Authors: Naschberger Christine , Finstad-Milion Krista 
Published: July 2017

PurposeThe purpose of this paper is to investigate how French managers picture their careers, specifically female careers.Design/methodology/approachThe sample was composed of 93 women and 5 men attending a professional women’s networking event in France. Participants answered a questionnaire, including images to choose from to best describe how they perceived their own career development.FindingsThe results indicate that a female career is closely associated with work-life balance by both women and men. Also, women acknowledge three times more than men, the existence of a glass ceiling in their organisation. Women and men choose both traditional and contemporary images of career.Research limitations/implicationsAs the sample was taken from a women’s network event, the male sample size is small. Despite the small sample of men, giving voice to male participants leads to rich insights which challenge gendered and non-gendered career models.Practical implicationsOn an individual level, reflection on one’s career path fosters awareness and ownership of career choices. Further, working with career images enhances discussion and experience sharing about personal career choices, and offers opportunities to organisations concerned with developing female talent.Originality/valueThe study contributes to the career literature by providing insights into how female and male managers perceive female careers. The study’s originality lies in the methodology, based on using images of careers to better understand how managers picture their own careers.
Recent immigrant newcomers’ socialization in the workplace
Authors: Malik Amina , Manroop Laxmikant 
Published: July 2017

PurposeDespite the increase of recent immigrant newcomers (RINs) into the workforce over the past few years, many employers still face the challenge of successfully integrating RINs into the workplace. To this end, the purpose of this paper is to propose customized socialization tactics for RINs and highlight the role of RINs’ adjustment strategies in order to facilitate their workplace adjustment.Design/methodology/approachDrawing on immigrants, socialization, and diversity literatures, the paper develops a conceptual model of the socialization process for RINs and advances propositions to be empirically tested.FindingsThe paper proposes that customized socialization tactics by organizations and adjustment strategies by RINs would facilitate RINs’ socialization process by increasing their social integration and role performance, the factors which would ultimately help in their workplace adjustment.Research limitations/implicationsThe proposed customized socialization tactics add to the extant socialization literature by highlighting the crucial role firms can play in RINs’ socialization process. Additionally, the paper highlights an important role of RINs in their own socialization process.Practical implicationsOrganizations need to employ new, different socialization tactics to help integrate RINs in the workplace. RINs may find the research outcomes useful in acknowledging their own role for successful workplace integration.Originality/valueThis paper presents a new way of looking at organizational socialization tactics for RINs while highlighting a role of RINs themselves, and concludes by discussing theoretical, practical, and societal implications for organizations employing RINs.
The impact of mood on decision-making process
Authors: Gear Tony , Shi Hong , Davies Barry J. , Fets Nagah Abdlelaziz 
Published: July 2017

PurposeThe purpose of this paper is to explore and analyze relationships between contextual factors, and micro-cognitive, emotional and relational factors, influencing the strategic decision-making process.Design/methodology/approachThe relative roles of “rationality,” “intuition” and “political behavior” in five recent and critical strategic decisions have been explored using 16 semi-structured interviews with senior decision-makers in three Middle Eastern Arabic commercial banks.FindingsContext specific macro-factors were found to influence the emotional state of strategists, leading them to adopt a rational approach, rather than use intuitive judgment, to making all five decisions.Research limitations/implicationsThe study was limited to one contextual situation and business sector in order to maintain these variables relatively constant, with proposals for extending studies to other business situations and contexts.Practical implicationsThe paper provides evidence for the impact of micro emotional and relational factors on decision-making practice, which should lead to increased recognition for strategists, and organizations, of the importance of these influences on strategic decision practice.Social implicationsA social implication is that organizations should build a level of awareness of the impact of the mood of strategists who are involved with strategic decisions, perhaps through appropriately designed social processes of organizational learning.Originality/valueThe paper examines the little-researched influence of the mood of strategists on the nature of decision-making process, and demonstrates the importance of including emotional factors in future studies. An explanatory framework is developed which is consistent with an interpretation that places the emotional state (mood) of “concerned attention” which existed within the senior management groups as the dominant factor driving the nature of process. A generalized research framework is proposed to aid future studies of strategic processes.
The impacts of quality and quantity attributes of Airbnb hosts on listing performance
Authors: Xie Karen , Mao Zhenxing 
Published: July 2017

PurposeWith the prevalence of the sharing economy phenomenon, there are an increasing number of hosts on Airbnb who manage more than one listing. Managing more listings likely makes hosts more seasoned in terms of serving guests, but it may undermine host quality due to hosts’ constrained capability. This paper aims to examine the effects of host quality attributes and the number of listings per host on the reservation performance of these listings.Design/methodology/approachUsing a large-scale but granular data set of 5,805 active listings of 4,608 Airbnb hosts in Austin, Texas, this study estimates the effects of host attributes (host quality and listing quantity) on the performance of the hosts’ Airbnb listings through a blend of regression models.FindingsThis study evidences that host quality attributes significantly influence listing performance through cue-based trust. In addition, this study finds a “trade-off” between host quality and the quantity of their listings. As the number of listings managed by a host increases, the performance effects of host quality diminish.Research limitations/implicationsThe business implications of this study include the suggestion that sharing economy businesses such as Airbnb should sustain service quality through incentivizing hosts to improve host quality while balancing the quantity of listings managed.Originality/valueThis study contributes to the literature through its meaningful theoretical extension in the sharing economy context and unique data-driven insights enabled by an analytical approach. It addresses the critical but less researched topic of host quality and listing quantity and generates important practical business and policy implications.
Developing a typology of disruptive customer behaviors
Authors: Gursoy Dogan , Cai Raine (Ruiying) , Anaya Gerardo Joel 
Published: July 2017

Purpose
This paper aims to examine the phenomenon of disruptive service behavior: an act by a customer that negatively affects the service experience of other customers and to identify typology of disruptive behaviors of customers that can negatively alter the service experiences of by-standing customers.

Design/methodology/approach
Anecdotes of customers’ service experiences that were negatively affected by the behavior of other customers were gathered from several customer review and discussion websites using a netnographic study approach. Data were analyzed using a qualitative data analysis approach with an iterative and inductive methodologies.

Findings
The analysis produced a typology featuring seven categories of disruptive behaviors of customers: “Inattentive Parents with Naughty Kids”, “Oral Abusers”, “Outlandish Requesters”, “Hysterical shouters”, “Poor Hygiene Manners”, “Service Rule Breakers” and “Ignorant Customers”.

Practical implications
Using the typology developed in this study, managers and operators of hospitality businesses can identify specific customer service behaviors and develop strategies and actions to minimize the impact of those behaviors on the service experience of other customers.

Originality/value
Even though a great deal of attention has been given to how employees can damage customers’ service experiences, much less work has been conducted on disruptive behaviors of customers as an influential factor of service quality and satisfaction. This study aims to address this gap in the literature by developing a typology of disruptive customer behaviors.
Amateur innkeepers utilization of minimum length stay restrictions
Authors: Kreeger Jeffery Cole , Smith Scott 
Published: July 2017

PurposeThe purpose of this paper is to determine how much the lodging shared economy (LSE) utilizes minimum length of stay (MLOS) controls to maximize revenue and reduce housekeeping expense, since cleaning between guest visits represents a substantial variable cost for each guest’s stay. Hosts in the LSE are becoming increasingly perceptive in maximizing revenues.Design/methodology/approachDaily data for one year were collected for Vacation Rental by Owner properties in Hilton Head Island, SC and Orlando, FL. The collected data include daily vacancies for two different lengths of stay. Linear regression was used to explore the relationship between relative demand and vacancy length of stay differences.FindingsDuring high-demand periods, there were few differences between the availability of short-term and longer-term reservation vacancies, which indicated hosts were not encouraging guests to stay longer during each visit. These results reveal differences in vacancies for three-night vs six-night reservations. A host can generate more revenue and decrease expenses by maximizing booked nights per visit.Research limitations/implicationsDue to confidentiality issues, this study does not capture vacation bookings but instead captures vacancies. In addition, Average Daily Rate was not utilized in this study.Practical implicationsLSE hosts can maximize revenues using MLOS controls. Minimizing housekeeping costs boosts a host’s profitability.Originality/valueAlthough this research has been conducted for hotel MLOS, there is a gap in the literature regarding LSE hosts’ use of MLOS.
