A precision analysis method for the kinematic assembly of complex products based on equivalence of deviation source
Authors: Zhao Dongping , Wang Gangfeng , Hui Jizhuang , Hou Wei , Evans Richard David
Published: February 2020

Purpose

The assembly quality of complex products is pivotal to their lifecycle performance. Assembly precision analysis (APA) is an effective method used to check the feasibility and quality of assembly. However, there is still a need for a systematic approach to be developed for APA of kinematic mechanisms. To achieve more accurate analysis of kinematic assembly, this paper aims to propose a precision analysis method based on equivalence of the deviation source.

Design/methodology/approach

A unified deviation vector representation model is adopted by considering dimension deviation, geometric deviation, joint clearance and assembly deformation. Then, vector loops and vector equations are constructed, according to joint type and deviation propagation path. A combined method, using deviation accumulation and sensitivity modeling, is applied to solve the kinematic APA of complex products.

Findings

When using the presented method, geometric form deviation, joint clearance and assembly deformation are considered selectively during tolerance modeling. In particular, the proposed virtual link model and its orientation angle are developed to determine joint deviation. Finally, vector loops and vector equations are modeled to express deviation accumulation.

Originality/value

The proposed method provides a new means for the APA of complex products, considering joint clearance and assembly deformation while improving the accuracy of APA, as much as possible.
Measuring the unknown
Authors: Begkos Christos , Antonopoulou Katerina
Published: February 2020

Purpose

In the current digital era where online content is riddled with fabricated metrics and rankings, this research aims to investigate the underpinning mechanisms of the calculative practices which actors engage with to evaluate digital platform content in the absence of well-defined performance measures.

Design/methodology/approach

The paper focuses on the online, photo-sharing platform Instagram which is devoid of common performance measures such as rankings, ratings and reviews. The authors applied netnographic methods to capture users' actions and interactions at the Greek Instagram community. The authors adopt a practice lens as informed by Schatzki's ‘site ontology’ to capture actors' calculative practices as organised by rules, teleoaffective structures and general and practical understandings.

Findings

Platform actors engage in aesthetic and palpable evaluations of other user profiles and their posted content. They employ permissible (e.g., using third-party apps) and illicit (e.g., lobbying and procuring engagement) tactics to measure and manage digital platform performance, fabricate metrics and blur others' evaluations, in pursuit of prestige and material teleologies. Their calculative practices are conditioned by an implicit social etiquette, which permeates the platform both horizontally and vertically.

Originality/value

First, the paper captures and theorises the mechanisms which underpin actors' calculative practices for performance measurement in the absence of robust judgement devices. Second, it demonstrates how ambiguous assemblages of material and prestige teleologies, aesthetic and palpable evaluative regimes and implicit rules and practical expertise collectively invoke platform actors' calculative practices and the construction of performance measures. In doing so, it contributes to performance measurement literature via demonstrating how management accounting is implicated in the evaluation of digital platform outputs.

Practical implications

The paper provides insight on how platform actors fabricate performance metrics, what they perceive as ‘good’ online content and what constitutes an ‘impactful’ user account or a ‘successful’ social media campaign. Such findings are valuable to management accountants, entrepreneurs and practitioners who seek to evaluate digital platform performance.
Relationships among employee acting, customer-perceived service quality, emotional well-being and value co-creation
Authors: Huang Chih-Hsuan , Lin Yuan-Chen
Published: February 2020

Purpose

Hinged on the transformative service paradigm, this study investigates the relationships among employee acting, customer-perceived service quality, customer emotional well-being, and their value co-creation. Feelings of gratitude among customers may moderate the effect of perceived service quality on their emotional well-being (i.e., positive and negative affects).

Design/methodology/approach

A pair study using a structural equation model was conducted to gather data from a financial service organization in a rural area.

Findings

The results show how customers perceive service quality positively impacts their emotional well-being immediately after receiving a financial service, which in turn affects their value co-creation. Hence, feelings of gratitude moderate the effect of perceived service quality on customer positive affect.

Originality/value

This study responds to calls for more studies on how service interactions influence customer well-being in the financial services context. This study is among the few that examine moderation effects of customer feelings of gratitude on their emotional well-being to explain why a positive emotion might sway their short-term well-being.
Using a look-up table technique and finite element calculations for quick detection of stiff inclusions in silicone rubber
Authors: Jonsson Ulf G. , Lindahl Olof A. , Andersson Britt M.
Published: February 2020

Purpose

The aim of the study was to show that a new method, using a look-up table technique, can be used to detect the presence and position of an inclusion embedded in a tissue-like material. Due to the time-consuming nature of the finite element (FE) method or FEM, real-time applications involving FEM as part of a control loop, are traditionally limited to slowly varying systems. By using a simplified two-dimensional FE model and a look-up table, we show by simulations and experiments that it is possible to achieve reasonable computational times in a tactile resonance sensor application.

Design/methodology/approach

A piezoelectric disk was placed in the center of a silicone rubber disk (SRD) with viscoelastic properties, where it acted as both sensor and actuator and dissipated radial acoustic waves into the silicone. The look-up table was constructed by calculating the radial Lamb wave transition frequencies in the impedance frequency response of the sensor while varying the position of an inclusion. A position-matching algorithm was developed that matched measured and calculated Lamb wave transitions and thereby identified the presence and position of an inclusion.

Findings

In an experiment, the position of a hard inclusion was determined by measuring the Lamb transition frequencies of the first radial resonance in two SRDs. The result of the matching algorithm for Disk 1 was that the matched position was less than 3% from the expected value. For Disk 2, the matching algorithm erroneously reported two false positions before reporting a position that was less than 5% from the expected value. An explanation for this discrepancy is presented. In a verifying experiment, the algorithm identified the condition with no inclusion present.

Originality/value

The approach outlined in this work, adds to the prospect of developing time-sensitive diagnostic instruments. This approach has the potential to provide a powerful technique to quickly present spatial information on detected tumors.
Formation of customer-based brand equity via authenticity
Authors: Rodríguez-López María Eugenia , del Barrio-García Salvador , Alcántara-Pilar Juan Miguel
Published: February 2020

Purpose

This study aims to examine the extent to which customers’ perceptions of restaurant authenticity facilitate the establishment’s customer-based brand equity (CBBE) – both directly and indirectly – via customer satisfaction. The study also analyzes whether restaurant type moderates the antecedent relationships of CBBE formation.

Design/methodology/approach

Two restaurants of different types were selected for the study: a mid-scale and a moderate/casual restaurant. Based on a final total sample of 402 customers of both restaurant types, a moderated mediation regression model was used.

Findings

It was found that the level of authenticity perceived by the restaurant visitor during the gastronomic experience is an antecedent of restaurant brand equity formation, both directly and indirectly, via customer satisfaction. Furthermore, these antecedent relationships were found to be partially moderated by restaurant type.

Research limitations/implications

Only two restaurants were used for the study. This study could be replicated by comparing other types of restaurants with differentiated characteristics to test whether the results obtained for these two types can be extrapolated to the rest.

Originality/value

There is no empirical evidence in the literature regarding the possible moderating effect of restaurant type on brand equity formation, so the particular note is the simultaneous application of CBBE measurement to the analysis of two different types of restaurant and the differences in their brand equity formation. On the other hand, there are few studies that use moderated mediation regression analysis as a methodological technique in the field of restaurants, so this is an interesting methodological contribution.
Testing moderating effects on the relationships among on-board cruise environment, satisfaction, perceived value and behavioral intentions
Authors: Calza Francesco , Pagliuca Margherita , Risitano Marcello , Sorrentino Annarita
Published: February 2020

Purpose

This study aims to investigate both the relationships among the on-board environment, overall satisfaction, perceived value and behavioral intentions and the moderating effects of gender, employment status, group composition and the propensity to stay on board in the context of cruise experience.

Design/methodology/approach

Relationships among constructs were tested on the basis of 417 surveys collected and analyzed with the structural equation modeling approach of partial least squares path modeling. A multi-group analysis was used to test the moderating effects.

Findings

The research findings suggest that on-board environment is a good predictor of behavioral intentions, but that the relationship is strongly mediated by satisfaction and perceived value. Moreover, the multi-group analysis of moderating effects indicated various differences that offer interesting insights for segmenting passengers; these insights have substantial implications for future studies and cruise line companies alike.

Practical implications

This study offers useful insights for managers who want to differentiate their value proposition with ship-centered elements.

Originality/value

This study contributes to the literature by providing a theoretical framework and empirical evidence for analyzing the role of the perceived on-board environment in passenger experience. From a managerial perspective, the moderating effects offer new insights for targeting and customizing the cruise experience value proposition.
Airbnb research: an analysis in tourism and hospitality journals
Authors: Andreu Luisa , Bigne Enrique , Amaro Suzanne , Palomo Jesús
Published: February 2020

Purpose

The purpose of this study is to examine Airbnb research using bibliometric methods. Using research performance analysis, this study highlights and provides an updated overview of Airbnb research by revealing patterns in journals, papers and most influential authors and countries. Furthermore, it graphically illustrates how research themes have evolved by mapping a co-word analysis and points out potential trends for future research.

Design/methodology/approach

The methodological design for this study involves three phases: the document source selection, the definition of the variables to be analyzed and the bibliometric analysis. A statistical multivariate analysis of all the documents’ characteristics was performed with R software. Furthermore, natural language processing techniques were used to analyze all the abstracts and keywords specified in the 129 selected documents.

Findings

Results show the genesis and evolution of publications on Airbnb research, scatter of journals and journals’ characteristics, author and productivity characteristics, geographical distribution of the research and content analysis using keywords.

Research limitations/implications

Despite Airbnb having a history of 10 years, research publications only started in 2015. Therefore, the bibliometric study includes papers from 2015 to 2019. One of the main limitations is that papers were selected in October of 2019, before the year was over. However, the latest academic publications (in press and earlycite) were included in the analysis.

Originality/value

This study analyzed bibliometric set of laws (Price’s, Lotka’s and Bradford’s) to better understand the patterns of the most relevant scientific production regarding Airbnb in tourism and hospitality journals. Using natural language processing techniques, this study analyzes all the abstracts and keywords specified in the selected documents. Results show the evolution of research topics in four periods: 2015-2016, 2017, 2018 and 2019.
Understanding the forces and critical features of a new reporting and budgeting system adoption by Indonesian local government
Authors: Harun Harun , Carter David , Mollik Abu Taher , An Yi
Published: February 2020

Purpose

This paper aims to critically explore the forces and critical features relating to the adoption of a new reporting and budgeting system (RBS) in Indonesian local governments.

Design/methodology/approach

The study is based on an intensive analysis of document sources and interview scripts around the institutionalization of RBS by the Indonesian government and uses the adaption of Dillard et al. (2004) institutional model in informing its findings.

Findings

The authors find that at the national level, the key drivers in RBS adoption were a combination of exogenous economic and coercive pressures and the wish to mimic accounting reforms in developed nations. At the local government level, the internalization of RBS is a response to a legal obligation imposed by the central government. Despite the RBS adoption has strengthened the transparency of local authorities reports – it limits the roles of other members of citizens in determining how local government budgets are allocated.

Research limitations/implications

The results of the study should be understood in the historical and institutional contexts of organizations observed.

Practical implications

The authors reinforce the notion that accounting as a business language dominates narratives and conversations surrounding the nature of government reporting and budgeting systems and how resource allocation is formulated and practiced. This should remind policymakers in other developing nations that any implementation of a new accounting technology should consider institutional capacities of public sector organizations and how the new technology benefits the public.

Social implications

The authors argue that the dominant role of international financial authorities in the policymaking and implementation of RBS challenges the aim of autonomy policies, which grant greater roles for local authorities and citizens in determining the nature of the budgets and operation of local authorities.

Originality/value

This study extends institutional theory by adapting the Dillard et al. (2004) model in explaining the forces, actors and critical features of a new accounting system adoption by local governments.
The Emotional experiences of children living in orphanages in Ghana
Authors: Boadu Selina , Osei-Tutu Annabella , Osafo Joseph
Published: February 2020

Purpose

This study aims to explore the emotional experiences of children in selected orphanages.

Design/methodology/approach

The study was executed in three orphanages in Accra, Tema and Aburi through the use of semi-structured interviews and observations.

Findings

In total, 15 respondents reported some emotional experiences such as loneliness, entrapment, deprivation, rejection and helplessness.

Originality/value

The number of children living in orphanages has increased in recent times. Previous studies have examined psychological risk and protective factors among children orphaned as a result of HIV/AIDS and also compared orphan children to non-orphans. Notwithstanding this, little is known about the emotional experiences of children living in orphanages in Ghana.
Implementation of a schema therapy awareness group for adult male low secure patients with comorbid personality difficulties: reflections and challenges
Authors: Lowenstein Joseph Aaron , Stickney Jennifer , Shaw Ida
Published: February 2020

Purpose

The purpose of this study/paper is to describe the implementation of a six-month schema therapy awareness (STA) group. Research supporting individual schema therapy (ST) as an effective intervention for personality disorder is growing steadily within a number of settings including with forensic patients. Alongside individual ST, positive results have been reported for group ST. However, to the best of the authors’ knowledge, no current published research exists with regard to the use of group ST within forensic populations and more specifically within a low secure environment.

Design/methodology/approach

This paper describes the implementation of a six-month schema therapy awareness (STA) group with individuals situated within a low secure environment.

Findings

For individuals transitioning into the community from a secure setting, the focus of risk management should attempt to move away from external controls towards more of a reliance on internal factors. In ST, this is achieved by understanding the role of schema modes (and underlying schemas) that are linked to an individual’s offences/risk and developing this understanding into a coherent and accessible formulation for the individual to make changes.

Research limitations/implications

Further robust research evaluating clinical change is recommended as the next step.

Practical implications

The group protocol is described along with the challenges and potential solutions experienced during the implementation. This provides an opportunity for other professionals to replicate this approach in the future.

Originality/value

With regard to group ST within forensic populations, the research is sparse at present and this study focusses on practical application of theory and the challenges of operationalising a STA group.
Breaking the health-care workplace conflict perpetuation cycle
Authors: Patton Cheryl M.
Published: February 2020

Purpose

The purpose of this study is to describe and interpret the interpersonal and intragroup conflict experiences of staff-level employees and leaders in the medical imaging technology field, working in US tertiary care centers to extract mitigation and management strategies.

Design/methodology/approach

A total of 13 medical imaging technologists, who were employed in leadership and staff positions throughout the USA, offered their in-depth accounts of workplace conflict in this interpretive phenomenological investigation.

Findings

Conflict avoidance was a predominant conflict management style. This style did little to effectively manage workplace conflict. In some cases, it led to deleterious effects on individuals and organizations and created conflict perpetuation. With proper conflict mitigation and management, the conflict perpetuation cycle can be broken.

Research limitations/implications

Generalization beyond the group being studied is not applicable, as it is not the intent of phenomenological research. Four leaders participated in the research study. To examine this population more completely, a greater sample size is required. This recommendation also applies to the staff technologist roles. Another limitation involved the leader/staff-level representation inequality, as well as the male–female representation. These imbalances made it difficult to effectively make comparisons of the experiences of leaders with staff-level technologists, and males with females.

Practical implications

Offering the medical imaging workforce emotional intelligence training, health-care administrators can invest in their leaders and staff technologists. Medical imaging schools can incorporate emotional intelligence training into their curricula. Clear policies may decrease the ill effects of change when unforeseeable occurrences result in schedule modifications. Making technologists fully aware of who is responsible for shift coverage when these events occur may reduce negative impact. Trainings in organizational change, collaboration or positivity may be warranted, depending on findings of cultural assessments. Team-building events and opportunities for employees to intermingle may also be used to improve a departmental or organizational culture.

Social implications

Mitigating and managing health-care workplace conflict more effectively may prevent patient harm, thus improving the health of members of society.

Originality/value

According to recent studies, conflict, and the incivility that often accompanies it, has been on the increase in US organizations overall, and in health care specifically. Conflict that perpetuates can adversely affect health-care organizations and its employees. This paper offers mitigation and management strategies to prevent such consequences.
The effects of the credit selection criteria on non-performing loans
Authors: Campanella Francesco , Gangi Francesco , Mustilli Mario , Serino Luana
Published: February 2020

Purpose

This paper aims to deal with the perceptions of banks’ managers about some criteria for assessing creditworthiness related to firms and how these criteria affect non-performing loans (NPLs). The paper wants to respond to the following research question: “Which criteria influence the magnitude of NPLs?” The evidence is based on the improvement of credit quality in the Italian banking system, which the authors study in aggregate and size-specific analyses, creating two subsamples (large and small banks).

Design/methodology/approach

The methodology used was a mixed method approach. The values of the variables were quantified according to the information derived from Thomson Reuters (Eikon, Datastream), the financial reporting of the banks and questionnaires directly administered to the bank managers.

Findings

This research about loans selection criteria provides useful indications for “The Basel Framework”. The results show that managers of the large banks are improving the approach of allocating the loans; the managers of the small banks are getting worse in the period 2006-2016. Therefore, it should be valuable to build a new standard about qualitative and quantitative criteria to recognize credit risk. In particular, these criteria could be adopted to reduce NPLs, and they should be different in small banks and large banks.

Originality/value

The study is part of empirical research investigating the causes of the significant increase in NPLs in the Italian banking system in 2006-2016. Most research interprets the increase in NPLs in the Italian banking system only as an effect of the crisis in the Italian entrepreneurial system. This research offers a different interpretation of the problem, interpreting the phenomenon as a delay of the banking system in investing in an effective information criterion.
Revenue-expense versus asset-liability model
Authors: Moscariello Nicola , La Rosa Fabio , Bernini Francesca , Fera Pietro
Published: February 2020

Purpose

The purpose of this study is to analyse the impact of two different financial reporting models (revenue-expense vs asset-liability) on several earnings attributes.

Design/methodology/approach

The analysis compares the earnings attributes of non-financial private firms using the Italian generally accepted accounting principles (Italian GAAP, based on a revenue-expense model) with those of the Italian non-financial private firms voluntarily adopting the international financial reporting standards (IFRS, based on the asset-liability model). To address major methodological concerns, the research design is based on a single-country analysis and on three different samples as follows: firms voluntarily adopting IFRS; a matched sample of Italian GAAP firms; Italian GAAP firms belonging to the Elite programme, and therefore, comparable to the IFRS adopters in terms of incentives towards financial reporting transparency.

Findings

The results show that firms reporting under a revenue-expense model are characterized by a stronger revenue-expense matching degree, along with higher earnings’ persistence, earnings’ predictability and conditional conservatism than firms adopting an asset-liability model. In addition, contrary to the expectations, Italian GAAP firms do not present smoother earnings and do not report greater abnormal accruals than IFRS adopters do. Overall, the findings suggest that the switch from a revenue-expense model to an asset-liability model negatively affects several earnings attributes of non-financial private companies, shedding new light on the drawbacks associated with the adoption of the IFRS accounting model.

Originality/value

This study addresses a theme characterized by sparse research efforts, adding new insights to the debate on the decline in the quality of earnings and on the drawbacks associated with the adoption of the IFRS accounting model.
Paternal psychopathology and maternal depressive symptom trajectory during the first year postpartum
Authors: D'Anna-Hernandez Kimberly L. , Zerbe Gary O. , Hunter Sharon K. , Ross Randal G.
Published: February 2020

Understanding parental psychopathology interaction is important in preventing negative family outcomes. This study investigated the effect of paternal psychiatric history on maternal depressive symptom trajectory from birth to 12 months postpartum. Maternal Edinburgh Postpartum Depression screens were collected at 1, 6 and 12 months and fathers' psychiatric diagnoses were assessed with the Structured Clinical Interview for DSM-IV from 64 families. There was not a significant difference in the trajectory of maternal depressive symptoms between mothers with partners with history of or a current psychiatric condition or those without a condition. However, mothers with partners with substance abuse history had higher levels of depressive symptoms relative to those affected by mood/anxiety disorders or those without a disorder. Our results call for a closer look at paternal history of substance abuse when treating postpartum maternal depression.
A self administered executive functions ecological questionnaire (the Behavior Rating Inventory of Executive Function - Adult Version) shows impaired scores in a sample of patients with schizophrenia
Authors: Bulzacka Ewa , Vilain Jeanne , Schürhoff Franck , Méary Alexandre , Leboyer Marion , Szöke Andrei
Published: February 2020

Subjective measurements of cognition have seldom been used in schizophrenia. This is mainly due to the assumption that such measurements lack sensitivity in a disorder characterized by poor insight. We investigated the capacity of BRIEF-A (Behavior Rating Inventory of Executive Function - Adult Version: a self-administered, ecological questionnaire) to identify executive deficits in adults with schizophrenia. The global score and each domain-specific score was significantly lower in patients than in healthy controls. BRIEF-A could be a useful complement to objective measurements, providing a subjective assessment of everyday consequences of executive dysfunction in patients with schizophrenia.
Decreased mental health care utilization following a psychosocial intervention in caregivers of hematopoietic stem cell transplant patients
Authors: Ouseph Rita , Croy Calvin , Natvig Crystal , Simoneau Teresa , Laudenslager Mark L.
Published: February 2020

Caregivers are known to experience increased morbidity when compared to noncaregivers. Does an intervention targeting caregiver distress affect their health care utilization? One hundred forty-eight caregivers of allogeneic hematopoietic stem cell transplant patients were randomized to treatment as usual (TAU) or a psychoeducation, paced respiration, and relaxation (PEPRR) intervention. Assessments of caregivers' service utilization were collected at baseline and 1, 3, and 6 months post-transplant. During the first 30 days after patient transplant, caregiver medical and mental health professional service use decreased while support group attendance peaked. Mixed model regressions showed a significant decrease in mental health service use by the PEPRR group (P=0.001). At six months caregivers in TAU had predicted marginal probabilities of mental health services utilization over 10 times as high as caregivers in PEPRR (18.1% vs 1.5%). Groups failed to differ in medical service (P=0.861) or support group (P=0.067) use. We can conclude that participation in PEPRR compared to TAU was associated with reduced mental health service utilization. Caregiver psychosocial support services are critical to improve caregiver outcomes.
Clozapine-induced liver injury and pleural effusion
Authors: Kane Joseph P.M. , O'Neill Francis A.
Published: February 2020

Clozapine, whilst associated commonly with a transient and benign increase in liver enzymes, has also been associated with varying presentations of hepatitis in existing case reports. This report describes what we believe to be the first documented case of acute liver injury and pleural effusion associated with clozapine, resolving after cessation of the agent. The case supports existing literature in advocating a high index of suspicion, particularly in the 4-5 weeks following clozapine initiation, when considering nonspecific clinical symptoms and signs.
Reactions of psychiatric patients to telepsychiatry
Authors: Campbell Robbie , O'Gorman Jennifer , Cernovsky Zack Z.
Published: February 2020

Telepsychiatry could offer a viable medical service to remote or isolated social communities if it does not generate adverse reactions such as delusional ideation, particularly in patients in settlements without adequate exposure to mainstream culture and internet. We examined subjective reactions to telepsychiatry of randomly selected 84 psychiatric patients from remote locations in Ontario, Canada. They rated the quality of their teleconferencing sessions via 10 item questionnaire and were asked about advantages and disadvantages of telepsychiatry. The majority of patients indicated that they were able to communicate as if physically present (92.9%) and were comfortable with telepsychiatric service (95.2%). They found the sessions as beneficial as direct meetings with their psychiatrist (84.5%) and would use this service again (98.8%). There were no instances of telepsychiatry being associated with adverse reactions in patients from remote communities with inadequate exposure to modern mainstream culture and internet.
Disability among attendees with schizophrenia in a Nigerian hospital: further evidence for integrated rehabilitative treatment designs
Authors: Olagunju Andrew Toyin , Adegbaju Dapo Adebowale , Uwakwe Richard
Published: February 2020

Evidence-based rehabilitative treatment is constrained due to limited knowledge about disability and its related factors among individuals with schizophrenia across West Africa. This study aims to investigate the pattern of disability, and the associated factors among individuals with schizophrenia. One hundred consecutively recruited consenting participants were subjected to designed questionnaire to inquire about their demographic and illness-related variables. This was followed by the administration of Structured Clinical Interview for DSM-IV-TR Axis I Disorders and Brief Psychiatric Rating Scale to confirm the diagnosis of schizophrenia and rate severity of symptoms respectively in them. In addition, the World Health Organisation Disability Assessment Scale II (WHODAS-II) was used to assess for disability in all participants. Different degrees of disability based on WHODAS-II mean score of 27.02±3.49 were noted among individuals with schizophrenia, and affectation of domains of disability like self care, getting along with others, life activities and participation in the society among others were observed. In addition, high level of disability was significantly associated with younger adults in the age group 18-44 years (P=0.007), unemployment status (P=0.003), remittance source of income (P=0.034) and ethnicity (P=0.017); conversely, less number of children (P=0.033), less amount spent on treatment (P<0.001) and lower BPRS score (P<0.001) correlated negatively with high level of disability. In spite of clinical stability following treatment, individuals with schizophrenia were disabled to varied degrees, and socioeconomic as well as illness-related factors constituted important correlates. Integration of rehabilitation along with social intervention into treatment design to reduce disability is implied, and further research is also warranted.
Medication adherence among Nigerians with schizophrenia: correlation between clinico-demographic factors and quality of life
Authors: Ogunnubi Oluseun P. , Olagunju Andrew T. , Aina Olatunji F. , Okubadejo Njideka U.
Published: February 2020

Medication adherence contributes significantly to symptom remission, recovery and wellbeing in mental illnesses. We evaluated how medication adherence correlates with clinico-demographic factors and quality of life (QoL) in a sample of Nigerians with schizophrenia. This descriptive cross-sectional study involved 160 randomly selected participants with confirmed diagnosis of schizophrenia based on MINI International Neuropsychiatric Interview. Data on socio-demographic and clinical characteristics of participants were collected with a questionnaire. Medication adherence was assessed with Morisky Medication Adherence Questionnaire, and participants completed the World Health Organization Quality of Life Scale-BREF. The mean age of participants was 38.54 (±11.30) years, and all the participants were on antipsychotics, but only 45% were adherent to their medication. Out of all the participants, 45 (28.2%) considered their overall QoL to be good, 97 (60.6%) considered theirs to be fair, while 18 (11.2%) reported poor QoL. Medication non-adherence correlated negatively with good QoL across multiple dimensions including overall QoL (r=−0.175), health satisfaction (r=-0.161), physical (r=-0.186) and psychological domain (r=-0.175). Again, participant's age (r=−0.190) and age of onset of illness (r=-0.172) correlated negatively with medication non-adherence, and a trend towards relapse delay with medication adherence was also observed (r=-0.155). The effect size of these correlations were however small. Our findings suggest a link between medication adherence and QoL in schizophrenia, such that strategy that addresses medication non-adherence and its determinants may have potential benefits on wellbeing. Further hypotheses-driven studies are desirable.
Social cognition in schizophrenia
Authors: Charernboon Thammanard , Patumanond Jayanton
Published: February 2020

Impairments in social cognitions in schizophrenia are increasingly reported in the last decade but only a few studies have come from Asia. The objective of the study was to evaluated emotion perception, theory of mind and social knowledge in people with schizophrenia compared to healthy controls. Participants were 36 clinically stable outpatients with schizophrenia and 36 normal controls with comparable age and level of education. We administered general neurocognition test (the Addenbrooke's Cognitive Examination), emotion perception (the Faces Test), theory of mind (the Eyes Test) and social knowledge (the Situational Features Recognition Test; SFRT). Schizophrenia patients displayed obvious impairment in all three social cognition domains i.e. the Faces Test [13.7 (2.9) vs 15.7 (1.9), P=0.001], the Eyes Test [18.9 (4.4) vs 23.5 (4.4), P<0.001] and SFRT [0.85 (0.09) vs 0.9 (0.05), P=0.002]. The performances on three social cognition tests did not correlate with positive symptoms. Only the Faces Test seemed to be related to negative symptoms. The results demonstrated that there are deficits of social cognitions in schizophrenia even in a clinically stable population.
A case of attempted bilateral self-enucleation in a patient with bipolar disorder
Authors: Castro Hannah Muniz , Alvarez John , Bota Robert G. , Yonkers Marc , Tao Jeremiah
Published: February 2020

Attempted and completed self-enucleation, or removal of one's own eyes, is a rare but devastating form of self-mutilation behavior. It is often associated with psychiatric disorders, particularly schizophrenia, substance induced psychosis, and bipolar disorder. We report a case of a patient with a history of bipolar disorder who gouged his eyes bilaterally as an attempt to self-enucleate himself. On presentation, the patient was manic with both psychotic features of hyperreligous delusions and command auditory hallucinations of God telling him to take his eyes out. On presentation, the patient had no light perception vision in both eyes and his exam displayed severe proptosis, extensive conjunctival lacerations, and visibly avulsed extraocular muscles on the right side. An emergency computed tomography scan of the orbits revealed small and irregular globes, air within the orbits, and intraocular hemorrhage. He was taken to the operating room for surgical repair of his injuries. Attempted and completed self-enucleation is most commonly associated with schizophrenia and substance induced psychosis, but can also present in patients with bipolar disorder. Other less commonly associated disorders include obsessive-compulsive disorder, depression, mental retardation, neurosyphilis, Lesch-Nyhan syndrome, and structural brain lesions.
The Turkish adaptation and psychometric properties of the Geriatric Anxiety Scale
Authors: Karahan Faika Sanal , Hamarta Erdal , Karahan Ali Yavuz
Published: February 2020

The purpose of the present study is to translate and adapt the Geriatric Anxiety Scale (GAS), a 30-item self-report measure of anxiety among older adults, into Turkish and examine its basic psychometric properties. We tested the translated GAS in a sample of community-dwelling older adults in Konya, Turkey (N=100; Mage=71.4 years, SD=6.5; range=65-88) without a history of mental disorder and sufficient cognitive abilities. To assess the convergent validity, Turkish versions of the Beck Anxiety Inventory (BAI) and Geriatric Depression Scale (GDS) were administered. The mean GAS total score was 13.33 (SD=11.86). Due to low item-total correlations (<0.30), two items (items 2 and 3) were removed from the Turkish version of the GAS. The internal reliability (Cronbach's alpha) was excellent for the total score (0.91) and acceptable for the subscales (somatic = 0.71; cognitive = 0.85; affective = 0.84). Regarding the convergent validity, the GAS total score was significantly and positively correlated with the total scores of the BAI (r=0.87, P<0.05) and GDS (r=0.57, P<0.05), with large effect sizes. Implications: The newly translated Turkish version of the GAS has promising utility in an older adult Turkish sample. Future studies of this measure are warranted.

Peduncluar hallucinosis is a rare neurological disorder characterized by visual hallucinations, often described to be vivid and dream-like. While the exact pathophysiology has yet to be elucidated, most cases to date have suggested an etiology stemming from lesions to the thalamus or midbrain. Here presented is a case of a 54-year-old female with peduncular hallucinosis secondary to a pontine cavernoma hemorrhage in the setting of essential hypertension. The patient's vivid visual and auditory hallucinations aligned temporally with the lesion's discovery and resolved after pharmaceutical treatment. This case represents a rare form of peduncular hallucinosis secondary to a pontine cavernoma hemorrhage leading to vasospasm in the arteries feeding the brainstem.
Extreme prolongation of expiration breathing: Effects on electroencephalogram and autonomic nervous function
Authors: Komori Teruhisa
Published: February 2020

To clarify the physiological and psychological effects of deep breathing, the effects of extreme prolongation of expiration breathing (Okinaga) were investigated using electroencephalogram (EEG) and electrocardiogram (ECG). Participants were five male Okinaga practitioners in their 50s and 60s. Participants performed Okinaga for 31 minutes while continuous EEG and ECG measurements were taken. After 16 minutes of Okinaga, and until the end of the session, the percentages of theta and alpha 2 waves were significantly higher than at baseline. After 20 minutes, and until the end of the session, the percentage of beta waves was significantly lower than at baseline. The high frequency component of heart rate variability was significantly lower after 12 minutes of Okinaga and lasted until 23 minutes. The low frequency/high frequency ratio was significantly lower after 18 minutes of Okinaga and until the end of the session. Okinaga produced relaxation, suggesting that deep breathing may relieve anxiety. However, study limitations include potential ambiguity in the interpretation of the low frequency/high frequency ratio, the small sample, and the fact that EEG was measured only on the forehead.

Emergency room have particularly stressful work situations. Emergency room personnel cope with stressors on a daily basis. These stressors can be risks factor for burn out and for reduced quality of life and work motivation. Emergency room staff of one of ASP 3 CT urban hospital in Acireale, Italy participated to stress management program by autogenic training twice a month for 16 weeks. This program were prepared based on existing research and studies, and were conducted by clinical psychologists. We found that the mean value in pre-test is significantly different from mean value in post-test for: Perceived Stress Scale PPS (t=7.72 with 27 df and P<0.001); Euro Quality for life (t=-14,13 with 27 df and P<0.001); Work motivation assessed by Visual Analogue scale VAS (t=-4.52 with 27 df and P<0.001). In the Maslach Burnout Inventory, the mean value is significantly different for emotional exhaustion sub-scale (t=5.64 with 27 with 27 df and P<0.001) and for depersonalization subscale (t=6.67 with 27 df and P<0.001). No significant difference was observed for the personal accomplishment sub-scale. This research suggests that psychological interventions with emergency room staff are effective. Our study showed effectiveness of an auto-genic and stress management training in improvement of quality of life, work motivation, burn-out and stress perceptions for emergency department team.
Interactions between antidepressants, sleep aids and selected breast cancer therapy

Depression and insomnia are very significant pathologies in cancer patients as they contribute to the patient's overall cure and quality of life. Moreover, untreated depression and ongoing insomnia are associated with decreased immune responses and lower survival rates. With all disease states and especially with cancer, close attention to drug-drug interactions and the potential impact on the efficacy of therapy is paramount. One area of particular interest due to the lack of well-done clinical trials is drug-drug interaction(s) between antidepressants and cancer treatment. Pharmacokinetics of a certain drug allows for prediction of certain drug interactions based on chemical properties of the agents involved. If the agents depend on their metabolites for activity, active drug level will be decreased through this enzyme inhibition. In this paper, we looked at the cytochrome-P450 drug interactions between antidepressants and sleep aids with Selective Estrogen Receptor Modulators (SERM). Newer SERM metabolisms are less influenced by interactions with medications used to treat depression. However, tamoxifen metabolism could be severely altered by several antidepressants. This has direct consequences as patients on tamoxifen and antidepressant can have double the risk of relapse to cancer in two years. We discussed those interactions and made recommendations for clinical use.
Time to remission analysis for major depressive disorder after repetitive transcranial magnetic stimulation (rTMS)

We previously examined the efficacy of rTMS for major depressive disorder in an applied clinical practice. Clinical response was related to severity of depression as well as the rTMS instrument utilized suggesting a relationship to instrument or magnetic field parameters and individual factors. The effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the treatment of major depressive disorder was further evaluated using Log-Rank statistics for time to remission outcomes. A follow-up retrospective medical records study was carried out on patients with major depressive disorder undergoing rTMS therapy at AwakeningsKC Clinical Neuroscience Institute (CNI), a suburban tertiary psychiatric clinic. Cox Proportional Hazard with Log-Rank statistics were applied and the time course to clinical remission was evaluated over a 6-week period with respect to age, gender, and depression severity. Clinical response was observed referencing two different rTMS instruments (MagVenture; NeuroStar). Time to remission studies of 247 case reports (N=98 males; N=149 females) showed consistently greater clinically defined remission rates after 6 weeks of rTMS treatment for patients using the MagVenture vs NeuroStar instrument. Patients previously admitted for inpatient psychiatric hospitalization exhibited higher response rates when treated with the MagVenture rTMS unit. Stepwise Cox Proportional Hazards Regression final model of time to remission included rTMS unit, inpatient psychiatric hospitalization and obese body habitus. Response to rTMS in applied clinical practice is related to severity of psychiatric illness and may require consideration of magnetic field parameters of the rTMS unit with respect to individual factors such as sex or body composition.
