Positive career shocks and career optimism: testing the mediating role of career decision-making self-efficacy
Authors: Ahmad Bilal , Nasir Nadia 
Published: October 2021

PurposeThis study examines the relationship of positive career shocks and career optimism. The mediating role of career decision-making self-efficacy (CDSE) between positive career shocks and career optimism and the moderating role of consideration of future consequences – immediate (CFC-I) between CDSE and career optimism are checked.Design/methodology/approachThrough cluster sampling, cross-sectional data from 192 professionals of electronic media industry were collected via an electronically administered questionnaire. For preliminary descriptive data analysis, SPSS version 21 was used. SmartPLS version 3.0 was used for testing the proposed hypotheses.FindingsThe results showed that positive career shocks have a relationship with career optimism via CDSE. Also, CFC-I moderated the relationship of CDSE and career optimism such that the relationship of CDSE and career optimism was stronger at higher level of CFC-I.Practical implicationsThe study provides implications for the career consultants, human resource professionals and senior management of organizations. All these stakeholders can strive to build an inventory of positive career shocks. Also, shifting to a surprised business model of announcing compensations and promotions is another area to work on. The results of this study further suggest disengaging the fresh potential employees in the initial processes of recruitment. Interdepartmental coordination of health and safety department and human resource management department is also a very important implication for this study to highlight the positive aspects of being optimistic.Originality/valueThe study is among the few empirical studies which investigates the relationship between positive career shocks and career optimism via CDSE. Also, in light of the latest call of various empirical works in the domain, this study adds a moderating variable, i.e. CFC-I in predicting career optimism. Furthermore, contrary to the conventional approach of applying students' data on career models, this study tests the proposed career model on data collected from professionals.

Authors: Zainal Siti Faizah , Hashim Hafiza Aishah , Ariff Akmalia M. , Salleh Zalailah 
Published: October 2021

Purpose
The purpose of this paper is to present a review of literature on fraud with a specific focus on small and medium enterprises (SMEs). Specifically, it aims to provide further knowledge on recent developments in fraud research and offers suggestions for future research.

Design/Methodology/Approach
This paper systematically reviews the fraud literature, by organising them into five sections; definition, elements, theories, factors and prevention mechanisms.

Findings
The most common factors of fraud in SMEs are the low morale among employees and weak internal control within the organisations. Nonetheless, research on fraud involving SMEs is limited, albeit the importance of SMEs to the economy.

Research Limitations/Implications
This paper encapsulates the importance of research on fraud in SMEs by offering directions for future research. Among others, future studies might indicate the link between corruption, financing sources and innovation of SMEs, especially within the context of an emerging country and reveal the cost of the criminal justice system to identify more accurately the cost of fraud in SMEs.

Originality/Value
The focus on fraud in SMEs and the recent period of study offer a foundation for future research directed at the factors of fraud and the prevention mechanisms. Future research can further explore and broaden the literature on fraud involving SMEs through research that focuses on the impact of fraud and the types of control mechanisms that suit the SMEs. Greater understanding of fraud in the SMEs allows in identifying the best approach to prevent and detect fraud for small businesses with limited resources.
Considering the role of context when implementing government policies in hospitals: introduction of a prospective payment system for psychiatry
Authors: Schippel Nicolas , Hower Kira Isabel , Zank Susanne , Pfaff Holger , Rietz Christian 
Published: October 2021

Purpose
The context in which an innovation is implemented is an important and often neglected mediator of change. A prospective payment system (PPS) for psychiatric and psychosomatic facilities with major implications for inpatient psychiatric care in Germany was implemented from 2013 to 2017. This study aims to examine the determinants of implementation of this government policy using the Diffusion of Innovations theory and consider the role of context.

Design/methodology/approach
An exploratory case study was conducted in two wards of a psychiatric hospital in Germany: geriatric psychiatry (GerP) and general psychiatry (GenP). Fifteen interviews were conducted with different occupational groups and analyzed in-depths. Routine hospital data were analyzed for delimiting the two contexts.

Findings
Routine hospital data show a higher day-mix index (1.08 vs. 0.94) in the GerP context and a very different structure regarding PPS groups, indicating a higher patient complexity. Two types of factors influencing implementation were identified: Context-independent factors included social separation between nurses and doctors, poor communication behavior between the groups and a lack of conveying information about the underlying principles of the PPS. Context-dependent factors included compatibility of the new requirements with existing routines and the relative advantage of the PPS, which were both perceived to be lower in the GerP context.

Practical implications
Depending on the patient characteristics in the specific context, compatibility with existing routines should be ensured when implementing. Clear communication of the underlying principles and reduction of organizational and communicative barriers between professional groups are crucial success factors for implementing such innovations.

Originality/value
This study shows how a diffusion process takes place in an organization even after the organization adopts an innovation. The authors could show how contextual differences in terms of patient characteristics result in different determinants of implementation from the views of the employees affected by the innovation.
How to decode the value-consequence-attribute relationship: the application of TISM and ANP techniques
Authors: Chang Kuei-Feng , Hsu Maxwell , Swanson Scott 
Published: October 2021

Purpose
This paper aims to facilitate positioning strategy formation by decoding the relationship between consumers’ desired values, service attributes and expected consequences.

Design/methodology/approach
Key informant depth interviews are followed by a questionnaire of self-cause-and-effect assessments. Total interpretive structural modeling (TISM) is used to identify hierarchical structures via pair-wise preference comparisons. The analytic network process (ANP) is used to compute relative weights to evaluate the overall image of identified alternatives. The feedback feature in the ANP is enabled to obtain objective assessments.

Findings
With the help of both TISM and ANP techniques, the hierarchical and interactive relationships among consumers’ desired values, expected consequences and service attributes are revealed in the context of international airline services.

Research limitations/implications
The approach presented can help organizations to identify which attributes influence consumer evaluations of a company/brand; obtain the hierarchical and interactive relationships among service attributes, expected consequences and desired values; assess consumer preferences toward identified service attributes; and obtain an objective assessment of the competitive landscape, which can facilitate the development of effective positioning strategies and associated tactics.

Practical implications
Organizations adopting the methods presented in this study can have a better understanding of the consumer value chain and deliver better customer experiences.

Originality/value
The current study provides an innovative application of the TISM in conjunction with a feedback-enabled ANP technique to address brand positioning challenges. Future studies may consider adopting the TISM-ANP method as a foundation whenever one attempts to explore the values-consequences-attributes hierarchy.

Digital elixir? The Aakash tablet as a social innovation in information and communication technology for development (ICT4D)
Authors: Abraham John , Geobey Sean 
Published: October 2021

Purpose
The Aakash tablet was developed as a social innovation (SI) to transform India’s higher education sector. This paper aims to explain the failure of the Aakash tablet beyond the typical explanations of deficiencies in the device’s technical capabilities. This paper argues that an SI lens provides a stronger explanation for its failure than the standard analyses built primarily on the technological viability of the device.

Design/methodology/approach
The Aakash project ran from 2010 to 2015. During this period, a number of government and policy reports as well as mainstream media articles were published on the device. Since 2015, a number of academic articles have been published on the Aakash emphasizing its failure as a technological solution. The authors draw on these sources to frame an understanding of the Aakash’s failure informed by SI theory.

Findings
Through a complexity-informed analysis, the authors show that the failure of the Aakash stemmed from flawed assumptions and a failure of the initiative to engage with both the particular and constantly changing features of the broader landscape of needs and opportunities.

Originality/value
This study draws attention to failure as a legitimate aspect of the study of SI. In presenting a “counter-case” to the usual success stories, it shows that the SI lens can also explain why an SI does not take off. It thereby adds to the literature on SI and complexity theory through an exploration of the complex interactions among public policy goals, technological advancements and entrepreneurship.
Infectious sporozoite challenge modulates radiation attenuated sporozoite vaccine–induced memory CD8+T cells for better survival characteristics
Authors: Yadav Naveen , Parmar Rajesh , Patel Hardik , Patidar Manoj , Dalai Sarat K. 
Published: October 2021

AbstractRadiation attenuated sporozoite (RAS), a whole‐parasite vaccine approach, provides sterile protection against malaria. However, RAS immunization does not confer protection for long, and that has been correlated with the waning parasite–induced memory CD8+T‐cell responses. Interestingly, an intermittent infectious (wild type) sporozoite challenge to the RAS‐vaccinated mice lengthened the protection period from 6 to 18 months. Herein, we have studied the changes induced by the infectious sporozoites in RAS‐induced memory CD8+T cells for conferring lengthened protection. We observed that the infectious sporozoite challenge boosted the frequency of foreign antigen–experienced memory CD8+T cells. In those CD8+T cells, it has reduced the Annexin‐V reactivity, raised Bcl‐2 expression, and also more cells undergo homeostatic proliferation (Ki‐67+). It has also scaled down the frequency of Nur77 and CX3CR1 high expressing cells in those memory CD8+T‐cell populations which we further correlated with better survival signals.
A role for PchHI as the ABC transporter in iron acquisition by the siderophore pyochelin in Pseudomonas aeruginosa
Authors: Roche Béatrice , Garcia‐Rivera Mariel A. , Normant Vincent , Kuhn Lauriane , Hammann Philippe , Brönstrup Mark , Mislin Gaëtan L. A. , Schalk Isabelle J. 
Published: October 2021

SummaryIron is an essential nutrient for bacterial growth but poorly bioavailable. Bacteria scavenge ferric iron by synthesizing and secreting siderophores, small compounds with a high affinity for iron. Pyochelin (PCH) is one of the two siderophores produced by the opportunistic pathogen Pseudomonas aeruginosa. After capturing a ferric iron molecule, PCH‐Fe is imported back into bacteria first by the outer membrane transporter FptA and then by the inner membrane permease FptX. Here, using molecular biology, 55Fe uptake assays, and LC–MS/MS quantification, we first find a role for PchHI as the heterodimeric ABC transporter involved in the siderophore‐free iron uptake into the bacterial cytoplasm. We also provide the first evidence that PCH is able to reach the bacterial periplasm and cytoplasm when both FptA and FptX are expressed. Finally, we detected an interaction between PchH and FptX, linking the ABC transporter PchHI with the inner permease FptX in the PCH‐Fe uptake pathway. These results pave the way for a better understanding of the PCH siderophore pathway, giving future directions to tackle P. aeruginosa infections.
Escherichia coli cryptic prophages sense nutrients to influence persister cell resuscitation
Authors: Song Sooyeon , Kim Jun‐Seob , Yamasaki Ryota , Oh Sejong , Benedik Michael J. , Wood Thomas K. 
Published: October 2021

SummaryCryptic prophages are not genomic junk but instead enable cells to combat myriad stresses as an active stress response. How these phage fossils affect persister cell resuscitation has, however, not been explored. Persister cells form as a result of stresses such as starvation, antibiotics and oxidative conditions, and resuscitation of these persister cells likely causes recurring infections such as those associated with tuberculosis, cystic fibrosis and Lyme disease. Deletion of each of the nine Escherichia coli cryptic prophages has no effect on persister cell formation. Strikingly, elimination of each cryptic prophage results in an increase in persister cell resuscitation with a dramatic increase in resuscitation upon deleting all nine prophages. This increased resuscitation includes eliminating the need for a carbon source and is due to activation of the phosphate import system resulting from inactivating the transcriptional regulator AlpA of the CP4‐57 cryptic prophage. Deletion of alpA increases persister resuscitation, and AlpA represses phosphate regulator PhoR. Both phosphate regulators PhoP and PhoB stimulate resuscitation. This suggests a novel cellular stress mechanism controlled by cryptic prophages: regulation of phosphate uptake which controls the exit of the cell from dormancy and prevents premature resuscitation in the absence of nutrients.
A major checkpoint for protein expression in Rhodobacter sphaeroides during heat stress response occurs at the level of translation

Published: October 2021

SummaryTemperature above the physiological optimum is a stress condition frequently faced by bacteria in their natural environments. Here, we were interested in the correlation between levels of RNA and protein under heat stress. Changes in RNA and protein levels were documented in cultures of Rhodobacter sphaeroides using RNA sequencing, quantitative mass spectrometry, western blot analysis, in vivo [35S] methionine‐labelling and plasmid‐borne reporter fusions. Changes in the transcriptome were extensive. Strikingly, the proteome remained unchanged except for very few proteins. Examples include a heat shock protein, a DUF1127 protein of unknown function and sigma factor proteins from leaderless transcripts. Insight from this study indicates that R. sphaeroides responds to heat stress by producing a broad range of transcripts while simultaneously preventing translation from nearly all of them, and that this selective production of protein depends on the untranslated region of the transcript. We conclude that measurements of transcript abundance are insufficient to understand gene regulation. Rather, translation can be an important checkpoint for protein expression under certain environmental conditions. Furthermore, during heat shock, regulation at the level of transcription might represent preparation for survival in an unpredictable environment while regulation at translation ensures production of only a few proteins.
