Borrowing books from a convenience store? An innovative library service
Authors: Hsiao Chun-Hua , Chang Jung Jung , Wu Pi-Chu , Tang Kai-Yu
Published: January 2020

Purpose

The purpose of this paper is to propose an innovative service model regarding the public library’s pilot project in Taiwan – Borrowing Books from Convenience Stores (BBCS). The proposed model presents a comprehensive evaluation of patrons to enhance readers’ intention to adopt this innovative library service.

Design/methodology/approach

A structured questionnaire was used to collect data from the users of the public library and convenience stores in Taiwan. Structural equation modeling was used to analyze the data.

Findings

The main findings of this study make both theoretical and practical contributions. First, this study explores the library’s extending service to convenience stores, and proposes an integrated BBCS model for the library’s innovative service. Second, the identification of influential factors, such as control influence, social interaction and perceived values of convenience, contributes to a marketing strategy for this innovative service offered by the library. Third, gender differences in some relationships of influential factors on BBCS use intention were identified.

Originality/value

Although many studies have investigated the adoption of self-service technology, this paper is the very first attempt to explore the use of the innovative library service in convenience stores. Based on several theories, an integrated model for users’ intention to use BBCS is proposed in this study. The authors also recommend various gender-specific strategies of BBCS service.
Diversity and future of work: inequality abound or opportunities for all?
Authors: Ozkazanc-Pan Banu
Published: January 2020

Purpose

The purpose of this paper is to examine new directions for diversity scholarship in the context of future of work or advanced technological shifts that are impacting organizations and society. It proposes that both new opportunities and challenges are likely to emerge for individuals and offers considerations around ethics, inequalities and global dimensions as relevant conversations within this domain.

Design/methodology/approach

The paper provides an overview of new technological advances in the domains of artificial intelligence, automation and the gig economy. It then layers considerations related to diversity within this context, focusing on issues of relevance to mainstream, critical and transnational traditions within diversity scholarship.

Findings

It is likely that technological shifts will impact several domains of diversity scholarship including how we define “diversity,” and the value and appropriateness of using advanced technologies to replace certain jobs that are predominantly held by underrepresented groups. Furthermore, the paper outlines ways in which bias, ethical considerations and emergent digital inequalities will become important conversations within diversity research in the context of future of work.

Originality/value

This paper brings together diversity scholarship and future of work conversations in assessing the ways such research and trends will intersect and provides insights about future directions that diversity-focused research should take to address and understand the consequences of rapid technological advances for inclusion.
Radical politics, intersectionality and leadership for diversity in organizations
Authors: Pullen Alison , Rhodes Carl , McEwen Celina , Liu Helena
Published: January 2020

Purpose

The purpose of this paper is to explore leadership for diversity informed by intersectionality and radical politics. Surfacing the political character of intersectionality, the authors suggest that a leadership for diversity imbued with a commitment to political action is essential for the progress towards equality.

Design/methodology/approach

Drawing lessons from the grassroots, political organizing of the black and Indigenous activist groups Combahee River Collective and Idle No More, the authors explore how these groups relied on feminist alliances to address social justice issues. Learning from their focus on intersectionality, the authors consider the role of politically engaged leadership in advancing diversity and equality in organizations.

Findings

The paper finds that leadership for diversity can be developed by shifting towards a more radical and transversal politics that challenges social and political structures that enable intersectionality or interlocking oppressions. This challenge relies on critical alliances negotiated across multiple intellectual, social and political positions and enacted through flexible solidarity to foster a collective ethical responsibility and social change. These forms of alliance-based praxis are important for advancing leadership for diversity.

Originality/value

This paper contributes to studies of leadership and critical diversity studies by articulating an alliance-based praxis for leadership underpinned by intersectionality, radical democracy and transversal politics.
The contingent effect of political ties on post-entry performance
Authors: Ma Jieqiong , Yang Jie , Song Ying
Published: January 2020

Purpose

Political ties are critical for multinational enterprises’ (MNE) survival and success. However, the effect of political ties is not monotonic. The purpose of this paper is to look into the contingent effect of political ties on MNEs’ post-entry performance.

Design/methodology/approach

Based on survey data collected from 416 foreign subsidiaries operating in China, which was combined with several secondary data sources, this study examined the three-way interaction of political ties, entry mode and industry restriction.

Findings

The findings support the hypotheses that the impact of political ties on firm performance is contingent on firms’ ownership-based entry modes and industry restriction. In particular, the impact of political ties is stronger for joint ventures (JV) in less restricted industries and wholly owned subsidiaries (WOS) in more restricted industries.

Practical implications

Political ties have different effects on WOS and JV. While in general political ties have a stronger impact for JV than for WOS, their impacts on both parties vary on industry restriction. Managers should consider ownership structure as well as industry restriction when making non-market strategies and decisions.

Originality/value

By analyzing the impacts of intra-organizational and market environmental factors, this study provides a fine-grained view of foreign firms’ non-market strategy in China from a post-entry performance perspective.
The myth of knowledge within a robust nutrition online training course
Authors: Weng Cathy , Matere Isaac Manyonge , Rathinasabapathi Abirami , Chu Anita Zichun
Published: January 2020

Purpose

The purpose of this paper was to develop a predictor model for an online nutrition course on sugar reduction. The proposed model is based on health knowledge, healthy behavior, social support, self-efficacy, attitude and the health belief model in relation to people’s behavior within a Facebook group. Subsequently, the model can be used to design a robust online training course for human resources, thereby reducing the training costs which managers have experienced as being expensive.

Design/methodology/approach

A single pre-post experimental group design was used. Pre and post data were collected from 100 Facebook users using an online questionnaire, within a three-week intervention.

Findings

The results show a significant difference between pre- and post-test scores of health knowledge and healthy behavior, indicating an effective intervention. In addition, perceived barriers, attitude, self-efficacy and emotional support were significant predictors of the healthy behavior model, predicting 70 percent of healthy behavior. However, knowledge had no significant relationship with any of the three dependent variables (self-efficacy, attitude and healthy behavior) proposed.

Practical implications

This model has proved to be an effective intervention which can be used in online training of human resources, because the content of the training is known from the predictor model, thereby greatly reducing the training cost, since everything is done online. Moreover, the provided model and predictors show that the content to be delivered in the training program is not knowledge but perceived barriers, attitude, self-efficacy and emotional support.

Originality/value

This study is one of the first to propose an integrative model that suggests attitude and self-efficacy as key predictors of healthy behavior whereas knowledge is not.
HowThe Waste Landfurthers an understanding of sustainable property management
Authors: Brown Alistair
Published: January 2020

Purpose

Using the theory of sensibility, the purpose of this paper is to analyze how T.S. Eliot’sThe Waste Landfurthers our understanding of sustainable property management.

Design/methodology/approach

Inter-connected indicators of environmental performance disclosures (EPD) and epistemological-based aesthetic environmental accounts (EBAEA) are used to textually analyzeThe Waste Land’sheightening of sustainable property management.

Findings

The results of the study show that the level of EPD ofThe Waste Landwas 80 per cent, while the level ofThe Waste Land’sEBAEA was 100 per cent. In terms of sustainable property management, the images of sustainable property management that permeateThe Waste Landfurthers our understanding of the apprehension of urban living, the intensification of assets and materials, the intrusiveness of city landmarks, the ephemeralness of the profit and loss, the inconstancy of water and the tension of torrid landscapes.

Research limitations/implications

A research implication arising from the results of the study is that the property-poetry nexus may actualize new possibilities for discerning and imagining sustainable property management.

Practical implications

The results of the study offer fruitful paths for understanding sustainability endeavour for planners, property managers, valuers, occupiers, accountants and developers.

Social implications

The Waste Land’scomplex, multi-vocal, figurative, seemingly ambiguous lines render a sophisticated form of sustainable property scholarship that shapes aesthetic environmental accounts.

Originality/value

The study’s originality rests in its methodological approach to identify, interpret and understand sustainable property management in a modernist poem.
Scale development and construct clarification of change recipient proactivity
Authors: Ahmad Ahmad Bayiz , Liu Bangcheng , Butt Atif Saleem
Published: January 2020

Purpose

The purpose of this paper is to develop a standardized, psychometrically sound instrument for the emerging construct of change recipient proactivity (CRP), using a deductive approach.

Design/methodology/approach

Using a systematic item-development framework as a guide (i.e. item generation, questionnaire administration, item reduction and scale evaluation) and based on a sample of 414 white-collar employees, this paper discusses the development and validation of an instrument that can be used to measure change recipient’s proactive behavioral responses to planned change efforts.

Findings

Results suggest that our proposed CRP scale is internally consistent (reliable) and valid in that it is conceptually distinct from, yet empirically correlated with neighboring constructs such as affective commitment to change, readiness for change and proactive personality.

Research limitations/implications

The findings illustrate that change recipients can demonstrate proactive behaviors in response to change efforts. However, this study’s contribution is only a first step, requiring further theoretical and methodological refinement of the scale in different contexts.

Originality/value

The deductive nature of our study resulted in a comprehensive and domain-specific scale assessing recipients’ proactive responses to organizational change efforts. This opens doors to empirical studies on examining the conditions under which change recipients “may” step outside the boundaries of passivity to respond positively and proactivity to organizational change efforts.
Understanding employees’ intrapreneurial behavior: a case study
Authors: Badoiu Georgiana-Alexandra , Segarra-Ciprés Mercedes , Escrig-Tena Ana B.
Published: January 2020

Purpose

The purpose of this paper is to provide a deeper insight into the organizational factors and personal motivations of intrapreneurs that may foster intrapreneurial behaviors of employees in a new technology-based firm (NTBF).

Design/methodology/approach

The paper takes a qualitative approach to explore organizational and individual antecedents of employees’ intrapreneurial behavior. A single case study was conducted on the basis of semi-structured interviews with the founders and top managers of the firm and with intrapreneurial employees.

Findings

Results show that intrapreneurial projects may arise in firms whose top managers support corporate entrepreneurship (CE) in a non-active manner. Intrapreneurial behaviors of employees can emerge despite the lack of time and limited resources available for undertaking projects. Moreover, work discretion and mutual confidence and the quality of the relationship between employees and top managers are the most valued factors for intrapreneurs.

Practical implications

Based on the intrapreneurial projects studied, this paper helps to contextualize intrapreneurs’ perception of organizational support and the personal motivations for leading projects within an NTBF.

Originality/value

Traditionally, the literature has mainly focused on the top-down implementation of entrepreneurial projects within large firms. This paper contributes to the understanding of the combination of firm- and individual-level factors that facilitate intrapreneurial behaviors of employees. It also illustrates the contextual conditions and the firms’ orientation on CE within an NTBF.
Retracted: Molecular insight into the selective binding between human telomere G‐quadruplex and a negatively charged stabilizer
Authors: Wang Zhiguo , Li Jianfeng , Liu Jun , Wang Lihui , Lu Yanhua , Liu Jun‐Ping
Published: January 2020

The single‐strand human telomere overhang forms intramolecular high‐order structures named G‐quadruplex (G4) under physiological conditions. Telomere G4 stabilization prevents telomere lengthening by telomerase in cancer cells representing a promising strategy in cancer therapy. Using molecular docking and molecular dynamics (MD) simulations, specific binding of the anionic phthalocyanine 3,4ʹ,4ʹʹ,4ʹʹʹ‐tetrasulfonic acid (APC) to the human hybrid (3 + 1) G4s was investigated at the atomic level. We found that APC preferred the end‐stacking binding with the telomere hybrid type II (hybrid‐II) G4 as compared to the groove binding with the hybrid type I (hybrid‐I) G4 remarkable stabilizing effect and more favourable binding free energies. Analysis of non‐covalent interaction and decomposition of the binding free energy revealed that van der Waals interaction played a leading role in the binding of APC and telomere hybrid G4s. These findings provide evidence for the first time to shed light on the designs of selective telomere G4 stabilizers.
Beyond Design for Manufacture: A Design Innovation Framework
Authors: Na Jea Hoo , Choi Youngok , Harrison David
Published: January 2020

Despite the advantages of using design on a larger scale than simply the product level, many manufacturing companies can't see their way to design as a strategy or a way to improve business management. A framework can help them view the big picture from a design innovation standpoint.

Manufacturing firms that hope to achieve innovation—in their products, in their processes, and in their own organizations—can use this framework to identify opportunities, prioritize problem‐solving, and work toward systematic improvement.
Do tone duration changes that elicit the mismatch negativity also affect the preceding middle latency responses?
Authors: Osakabe Yusuke , Shiga Tetsuya , Hoshino Hiroshi , Kanno Kazuko , Wada Tomohiro , Ochiai Haruka , Itagaki Shuntaro , Miura Itaru , Yabe Hirooki
Published: January 2020

The human brain can automatically detect sound changes. Previous studies have reported that rare sounds presented within a sequence of repetitive sounds elicit the mismatch negativity (MMN) in the absence of attention in the latency range of 100–250 ms. On the other hand, a previous study discovered that occasional changes in sound location enhance the middle latency response (MLR) elicited in the latency range of 10–50 ms. Several studies have reported an increase in the amplitude of the MLR within the frame of oddball paradigms such as frequency and location changes. However, few studies have been conducted on paradigms employing a duration change. The purpose of the present study was to examine whether the peak amplitudes of the MLR components are enhanced by a change in duration. Twenty healthy Japanese men (age: 23.9 ± 2.9 years) participated in the present study. We used an oddball paradigm that contained standard stimuli with a duration of 10 ms and deviant stimuli with a duration of 5 ms. The peak amplitudes of the MLR for the deviant stimuli were then compared with those for the standard stimuli. No changes were observed in the peak amplitude of the MLR resulting from a duration change, whereas a definite MMN was elicited. The amplitude of the MLR was increased within the frame of oddball paradigms such as frequency and location changes. By contrast, the amplitude of the MLR was not changed within the duration change oddball paradigm that elicited the MMN.

Authors: Gupta Deepak , Sharma Prerna , Choudhary Krishna , Gupta Kshitij , Chawla Rahul , Khanna Ashish , Albuquerque Victor Hugo C. de
Published: January 2020

Plant leaves play an important role in the diagnosis of plant diseases. Losses from such diseases can have a significant economic as well as environmental impact. Thus, examination of leaves into a healthy or infected carries substantial importance. An improved artificial plant optimization (IAPO) algorithm using machine learning has been introduced that identifies the plant diseases and categorize the leaves into healthy and infected on a private dataset of 236 images. Features are extracted from the images using histogram of oriented gradients (descriptor). The concepts of artificial plant optimization are then applied to study the features of healthy leaves using IAPO. A machine learning algorithm has been created to make the model adaptive with varied datasets. The degree of infection is eventually computed, and the leaves with infection greater than a certain calculated threshold are classified as infected leaves. The results show that IAPO can be used for classification of infected and healthy leaves and this algorithm can be generalized to solve problems in other domains as well. The proposed IAPO is also compared with other classification algorithms including k‐nearest neighbours, support vector machine, random forest and convolution neural network that show accuracies of 78.24%, 83.48%, 87.83%, and 91.26%, respectively, whereas IAPO shows quite accurate results in classification of leaves with an accuracy of 97.45% on training set and 95.0% accuracy on test set.

Published: January 2020

SYPRENE, a new international Systemic Practice Research Network (PRN), has been established to fill the gap in practice‐based research on the effectiveness and efficiency of strategic therapies. This article presents the rationale for the creation of SYPRENE and describes data collection methods, and the encoding system implemented within this PRN. More developments are expected in the recruitment of practitioners, the types of data collected, findings, and the implementation of SYPRENE in supervision, trainings, and professional schools.
The consequences of migration for the migrants' parents in Bolivia
Authors: BASTIA TANJA , VALENZUELA CLAUDIA CALSINA , POZO MARIA ESTHER
Published: January 2020

The existing literature on transnational care suggests that it is possible to care for ageing parents from afar. However, most of these studies are based on research in higher‐income countries, where families have access to institutional support and where travel and communication networks are generally of high quality. Studies focusing on lower‐income countries of origin have found a greater likelihood of migrants' parents being in a vulnerable situation. Here, though, there has been a preference for focusing on rural areas. In this article, we address this gap by reporting on a research project that spans rural, urban and peri‐urban areas, as well as different migration streams (regional South–South and South–North), and ask how migrants' parents fare during their adult children's absences in a context of very weak institutional support, widespread poverty and inequality. We find that parents in urban and peri‐urban areas are generally better able to negotiate their adult children's absences, while those in rural areas experience an increase in their vulnerability. However, there are also stories that are in tension with these general trends, which indicates that social networks, migrants' destinations and parents' socio‐economic statuses also mediate the availability of transnational care.
Hall technique crowns and children's masseter muscle activity: A surface electromyography pilot study
Authors: Abu Serdaneh Salsabeel , AlHalabi Manal , Kowash Mawlood , Macefield Vaughan , Khamis Ammar H. , Salami Anas , Hussein Iyad
Published: January 2020

Background

Hall technique crowns (HTCs) alter the occlusion temporarily, potentially affecting jaw muscles, particularly the masseter – the primary jaw‐closing muscle.

Aim

To assess masseter muscle activity (MMA) in children treated with a unilateral HTC.

Design

In 12 children treated with a single HTC, bilateral MMA was recorded with surface electromyography (sEMG) for ten cycles of Rest Position (RP) and Maximum Voluntary Clenching (MVC) over 20 seconds immediately pre‐HTC cementation (Pbase), immediately post‐HTC cementation (Pimmed), at 2 weeks post‐HTC cementation (P2w) and at 6 weeks post‐HTC cementation (P6w). t test, ANOVA and post hoc statistics were used (P < .05).

Results

As expected, MMA was low at rest and increased during maximal jaw clenching (P < .0001). MMA (mean ± SD) increased significantly (P < .001) between RP and MVC at: Pbase [from 1.60 μV·s (±0.96) to 5.40(±2.30)]; Pimmed [1.57(±1.15) to 3.75(±1.87)]; P2w [1.39(±0.54) to 5.54(±1.45)] and finally P6w [1.46(±0.56) to 6.45(±2.56)]. Rest MMA at Pbase, Pimmed, P2w and P6w remained unchanged (P = .18) whereas Pbase clench MMA reduced by a third at Pimmed (P < .001), returned to and exceeded baseline levels at P2w (P = .822) and P6w (P < .001), respectively.

Conclusions

This pilot study showed that Hall technique crowns may affect masseter muscle activity in children. Clench MMA was reduced immediately post‐treatment but returned to and later exceeded baseline levels at 2 and 6 weeks, respectively. Rest MMA remained unchanged.
Porous SiOC monoliths with catalytic activity by in situ formation of Ni nanoparticles in solution‐based freeze casting
Authors: Schumacher Daniel , Wilhelm Michaela , Rezwan Kurosch
Published: January 2020

Micro‐ and macroporous monoliths with in situ formed nickel nanoparticles were prepared for the first time by the combination of solution‐based freeze casting and preceramic polymers (methyl polysiloxane). This one‐step process results in macroporous monoliths composed of microporous and catalytic active nickel‐containing polymer‐derived ceramic. Four different complexing and cross‐linking siloxanes with amino functionality were screened for their ability to create small nickel particles. TEM analysis confirmed 3‐aminopropyltriethoxysilane being most efficient. High BET‐specific surface areas of 344‐461 m2 g−1 were achieved. Increased ratio of complexing groups to nickel improves the dispersion of nickel to (3.61 ± 1.49) nm. The nickel size dependence of conversion (maximum 0.49) and CH4 selectivity (maximum 0.74) in CO2 methanation emphasizes the importance of controlling the nickel size. The hydrophobic surface characteristic is hypothesized to be the main reason polymer‐derived catalysts having better catalytic activity compared with nickel‐impregnated silica. The promising catalytic activity combined with the versatile freeze casting process can prospectively address heat‐ and mass‐transfer considerations in heterogeneous monolith catalysis.
Oral health–related food selectivity among French independently living elders
Authors: Maitre Isabelle , Lourtioux Flore , Picouet Pierre , Braud Adeline
Published: January 2020

Impaired oral conditions are described as influencing food intake behaviour and contributing to poor nutritional status in elderly persons. In order to evaluate the influence of age and oral factors on food choice among independently living elderly, we investigated food selectivity and oral health status in elders (aged over 65 years) and in younger people (aged between 35 and 64 years). Food selective behaviour was appraised by using a food selectivity questionnaire based on traditional French dishes. A stepwise binary logistic regression analysis was done to sequentially identify age and oral conditions associated with oral discomfort–related food avoidance. Occlusal status and oral health–related quality of life contributed to food choice. Risk of oral discomfort–related food avoidance was significantly increased in people with fewer than seven occlusal functional units (OFUs) and with Geriatric Oral Health Assessment Index summary scores (GOHAI‐ADD) indicating poor and average oral health–related quality of life (P < .05). Age was never a significant factor of food selective behaviour. The present data support the impact of occlusal status and oral health–related quality of life on food behaviour. Specific attention should be given in maintaining or restoring good oral conditions throughout the lifespan, especially occluding teeth.
Unraveling the extreme morphological variation in the neotropical Ficus aurea complex (subg. Spherosuke, sect. Americanae, Moraceae)

Published: January 2020

Ficus (Moraceae) is one of the most diverse genera of tree species in the world. The subgenus Spherosuke, section Americanae, comprises several species complexes because its diagnostic structures are extremely variable. Currently, neither there is a phylogenetic hypothesis that can help solve the delimitation problems within these complexes nor has an integrative taxonomic approach been developed. In the present study, morphometric methods were applied to solve the taxonomic problems in the Ficus aurea complex. Morphometric variation of syconia and leaves was analyzed to find differences between four previously recognized forms (fo. aurea, fo. cookii, fo. isophlebia, and fo. tuerckheimii). Syconium characters were analyzed using traditional morphometrics, while leaf shape was evaluated with geometric morphometrics, encompassing 20 populations along two‐thirds of the distribution range of the complex. Data sets from syconia and leaves were tested for possible associations with geographic and rainfall variables. There are significant differences between the four forms in syconium characters and leaf shape. Geography and rainfall variables show significant covariation related to the morphometric variation of syconia but not to leaf shape. Consequently, we propose that the four forms should be repositioned into the specific rank. Besides, F. tecolutensis is also recognized as a separated species from form aurea considering Principal Component Analysis, field observations, and herbarium specimens. An identification key, descriptions, as well as taxonomic comments of the species are provided.
Reducing postoperative nausea and vomiting in pediatric patients undergoing anterior cruciate ligament reconstruction: A quality report
Authors: Muhly Wallis T. , Ganley Theodore , Jantzen Ellen , Browne Patricia , Kerr Joy , Gurnaney Harshad G. , Kraemer Francis Wickham , Galvez Jorge , Keren Ron , Wells Lawrence
Published: January 2020

Background

Postoperative nausea and vomiting after elective outpatient surgery can complicate discharge and increase patient suffering. Within our hospital system, there was variability in the use of postoperative nausea and vomiting prophylaxis for patients undergoing anterior cruciate ligament reconstruction, which resulted in variable outcomes. To address this variability, we designed and implemented a standardized postoperative nausea and vomiting prophylaxis guideline for the care of this surgical population.

Aim

We sought to develop and implement a standardized postoperative nausea and vomiting prophylaxis guideline for all patients presenting for elective ambulatory anterior cruciate ligament reconstruction with the goal of reducing the rate of emesis to ≤5%.

Methods

We convened a multidisciplinary team to develop a postoperative nausea and vomiting prophylaxis guideline which included administration of dexamethasone, ondansetron, and a low‐dose propofol infusion in addition to a femoral and sciatic nerve block and routine ketorolac administration for pain control. Our primary outcome, emesis rate, was tracked using a P‐chart. Process measures included use of guideline medications and balancing measures included opioid administration, pain scores, and emergence time.

Results

We analyzed postoperative nausea and vomiting outcomes for 817 patients from January 1, 2014, to December 31, 2018. The baseline postoperative emesis rate for all anesthetizing locations was 17%. Following, guideline implementation, the emesis rate decreased to 5%. Opioid administration was decreased following guideline implementation. The percentage of patients managed without any perioperative opioids increased from 16% in the baseline group to 38% following guideline implementation. The P‐chart suggests that the observed reduction in emesis rate represents special cause variation and this reduction was sustained over a two‐year period.

Conclusions

Implementation of standard postoperative nausea and vomiting guidelines for adolescents undergoing outpatient anterior cruciate ligament reconstruction was associated with lower emesis rates. This reduction in emesis rate may have been due to the concurrent reduction in opioids we observed following guideline implementation.
Patient perfectionism and clinician impression formation during an initial interview
Authors: Hewitt Paul L. , Chen Chang , Smith Martin M. , Zhang Lisa , Habke Marie , Flett Gordon L. , Mikail Samuel F.
Published: January 2020

Objectives

The negative impact of pre‐treatment patient perfectionism on therapeutic alliance and outcomes has been well documented. However, there is much to learn about how patient perfectionism impacts the development of the therapeutic alliance. Our study addressed this by examining the extent to which trait and self‐presentational components of perfectionism influence clinician’s perceptions of patients during an initial interview.

Design

In a re‐analysis of data from Hewitt et al., 2008, Psychiatry, 71, 93–122, participants were 90 treatment‐seeking adults (aged 19–64, Mage = 36.2; 40 men) recruited from outpatient mental health clinics. Each patient had a one‐on‐one, semi‐structured interview with a clinician that lasted approximately 50 min.

Method

Patients completed self‐report measures assessing trait perfectionism, perfectionistic self‐presentation, and symptom distress before the interview. Patients were then invited to discuss reasons for seeking treatment and to reflect on the two most challenging situations in their lives in which they had not coped well. Following the interview, clinicians indicated their overall impressions of patients by responding to three self‐report questions and rated patients’ distress and hostility via nine adjectives.

Results

After controlling for patients’ symptom distress, other‐oriented perfectionism and non‐display of imperfection had small positive relationships with clinician‐rated hostility; self‐oriented perfectionism, socially prescribed perfectionism, and non‐disclosure of imperfection had small‐to‐moderate negative relationships with clinician impressions. Additionally, path analysis revealed other‐oriented perfectionism and non‐display of imperfection indirectly predicted less favourable clinician impressions through clinician‐rated hostility.

Conclusions

Findings highlight the importance of evaluating and addressing trait and self‐presentation components of perfectionism early in the therapeutic process.

Practitioner points

Higher levels of other‐oriented perfectionism and non‐display of imperfection were associated with greater clinician‐rated hostility during an initial interview.

Patient hostility mediated the relationship between patients’ other‐oriented perfectionism, non‐display of imperfection, and less favourable clinician impressions.

Our study highlights the importance of assessing and attending to patient perfectionism and displays of hostility during the earliest stages of therapeutic contact.
Evidential Preemption
Authors: Begby Endre
Published: January 2020

As a general rule, whenever a hearer is justified in forming the belief that p on the basis of a speaker’s testimony, she will also be justified in assuming that the speaker has formed her belief appropriately in light of a relevantly large and representative sample of the evidence that bears on p. In simpler terms, a justification for taking someone’s testimony entails a justification for trusting her assessment of the evidence. This introduces the possibility of what I will call “evidential preemption.” Evidential preemption occurs when a speaker, in addition to offering testimony that p, also warns the hearer of the likelihood that she will subsequently be confronted with apparently contrary evidence: this is done, however, not so as to encourage the hearer to temper her confidence in p in anticipation of that evidence, but rather to suggest that the (apparently) contrary evidence is in fact misleading evidence or evidence that has already been taken into account. Either way, the speaker is signalling to the hearer that the subsequent disclosure of this evidence will not require her to significantly revise her belief that p. Such preemption can effectively inoculate an audience against future contrary evidence, and thereby creates an opening for a form of exploitative manipulation that I will call “epistemic grooming.” Nonetheless, I argue, not all uses of evidential preemption are nefarious; it can also serve as an important tool for guiding epistemically limited agents though complex evidential scenarios.

Published: January 2020

Composite lymphoma is a well‐known diagnostic entity exhibiting the synchronous occurrence of two or more distinct types of lymphomas in the same specimen. Here we report two patients, a 14‐year‐old female (Case 1) and a 45‐year‐old male (Case 2), with mediastinal composite lymphoma, comprising nodular sclerosis classic Hodgkin lymphoma (NSCHL) and primary mediastinal large B‐cell lymphoma (PMBL). Both patients had a mediastinal mass, and manifested two different histologic components in the same biopsy, one characteristic of NSCHL and the other PMBL. The NSCHL areas included Hodgkin and Reed–Sternberg (HRS) cells with typical immunophenotypic features (CD30‐positive and CD20‐negative), whereas the sheets of large tumor cells characteristic of PMBL were strongly and uniformly CD20‐positive. Interestingly, although both cases showed neoplastic PD‐L1 (nPD‐L1) positivity on the HRS cells of NSCHL, they differed regarding nPD‐L1 expression on the PMBL tumor cells. In Case 1, the nPD‐L1‐negative PMBL component was anatomically situated outside the NSCHL lesion. On the other hand, in Case 2, the nPD‐L1‐positive PMBL component was characterized by transitional or continuous areas with the NSCHL component. These findings suggested that nPD‐L1 expression may define two subtypes of PMBL that are more similar to or distinct from classic Hodgkin lymphoma.
Effects of mineral supplementation on reproductive performance of pregnant cross‐breed Bonsmara cows: An experimental study
Authors: Molefe Keitiretse , Mwanza Mulunda
Published: January 2020

Minerals in animal feed occur in variable structures, most of which determine the uptake and usage in biological processes in the body. Effective chemical breakdown of minerals may ensure efficient utilization in metabolism. The aim this study was to evaluate the effects of mineral supplementation on reproduction in cows. A farm was selected for the experiment due to the fact that it previously experienced different reproductive conditions in the farm. The farm comprises cross‐breed cows with Bonsmara dominating in the farm. Twelve pregnant primiparous and multiparous cows of different ages, parity and weight, that had previously experienced reproductive conditions, were randomly selected for this study. The cows were then randomly sub‐divided into two groups (experimental and control group) of six. The experimental group was injected with MULTIMIN™ + Se + Cu at a dosage of 1 ml/45 kg BW and Calci 50 p.i. at a dosage of 100–150 ml/500 kg BW at an interval of 6 weeks (from June to October 2017). Blood samples were collected before every injection date. The t test was used to relate the mean weight gain and serum metabolite between the experimental and control groups. The body weight gain was significantly higher in the experimental group compared to the non‐supplemented group. Supplemented cows had significantly (p < .05) high levels of triglycerides and creatinine kinase. A case of retained placenta and dystocia among non‐supplemented cows were noted. Thus, mineral supplementation can be used to improve productivity and reproductive well‐being.

Bronchial collapse due to bronchomalacia is an important cause of chronic coughing in dogs. Radiographic and CT evidence of bronchial collapse has previously been reported in healthy Beagle dogs under forced expiration. However, published studies in brachycephalic dog breeds that are prone to bronchial collapse are currently lacking. In the present prospective analytical experimental study, CT and radiography were used to measure the bronchial diameter and collapsibility of each pulmonary bronchus during end‐expiratory, 5 mL/kg forced‐expiratory, and 10 mL/kg forced‐expiratory phases in 17 asymptomatic brachycephalic dogs and six healthy Beagle dogs. Bronchial collapsibility was significantly greater during forced expiration, than that at the end of expiration in both groups (P < .001). Bronchial collapsibility measurements of the left lung lobes and the right cranial, middle, and accessory lobes were significantly higher in asymptomatic brachycephalic dogs than those in healthy Beagle dogs, during all expiratory phases (P < .05). The higher bronchial collapsibility of brachycephalic dogs was also supported using CT multiplanar reconstruction images and radiography. In conclusion, radiographic and CT measures of bronchial collapsibility in asymptomatic brachycephalic dogs are higher than measures in healthy Beagle dogs. Therefore, measures of bronchial collapse in brachycephalic dogs should not be evaluated using the same baseline measures as those used for healthy Beagle dogs.
Ultrasound‐guided arthrocentesis of the temporomandibular joint in healthy adult horses is equivalent to blind arthrocentesis

Equine temporomandibular joint (TMJ) diseases are increasingly recognized as a problem for the well‐being and performance of horses. Diagnosis is confounded by overlap of clinical signs associated with pathology of the oral cavity, poll, and cervical vertebrae. Arthrocentesis for intra‐articular analgesia, sampling of synovial fluid, and medication is needed for diagnostic and therapeutic purposes. Ultrasound features of the normal TMJ and a blind arthrocentesis technique have been described, but a systematic approach to ultrasound‐guided (USG) arthrocentesis has not been reported. Ultrasound guidance allows visualization of the TMJ that may prove beneficial in cases when pathology, abnormal anatomy, or clinician inexperience make blind arthrocentesis difficult. We hypothesized that USG arthrocentesis would result in fewer needle repositions than blind arthrocentesis. We also aimed to assess synovial fluid parameters for normal equine TMJs. A prospective randomized method comparison with crossover experimental design compared the number of needle positionings required for accurate injection of the TMJ using each technique. Arthrocentesis technique and operator experience were tested using cadavers and two operators. Injection success was confirmed using CT. The radiologist then applied both techniques in normal live horses. No statistically significant difference was noted between arthrocentesis techniques or operators (P > .05). No complications were observed in live horses following either technique. Synovial fluid parameters were largely within the normal range expected for other synovial joints. Either blind or USG arthrocentesis of the equine TMJ can be performed with minimal prior operator experience. Ultrasound‐guided arthrocentesis is an alternative method and can be considered in cases with altered anatomy.

Information and communication technologies (ICT) have been proven beneficial in teaching of health sciences courses. Combined e-learning strategies with face-to-face activities, among others, are defining characteristics of a new learning perspective called blended learning methods. The paucity of data to confirm the benefits of online forms of learning, in isolation or as a part of a blended learning method, indicates that more studies are still required to assess their influence on the teaching-learning process. This study measured knowledge gained using face-to-face (FtFA) and distance educational on virtual learning environments (DA-VLE) strategies in health sciences. For two consecutive years, FtFA and DA-VLE education strategies were used in a discipline of specialization graduate course, each discussing two topics. The knowledge gained using each strategy was assessed for each topic using a pre (PT) and post-test (PoT). The performance frequency (PF) of participants was categorized based on the number of correct answers in each assessed. The PF frequency increased between the PA and PoT in both strategies (FtFA and - DA-VLE), although higher scores were observed in DA-VLE strategies when compared to FtFA strategies. These data indicate that such strategies, within this context, are vital, and can bring benefits to the teaching-learning process in combination.
Optimization-Based Energy Management Strategy for a 48-V Mild Parallel Hybrid Electric Power System
Authors: Wang Ying , Huang Zhiyong
Published: January 2020

The application of a 48-V mild hybrid powertrain system is one of the eco-friendly technologies for global CO2 reduction in the present sector of hybrid electric vehicles (HEVs). It is well known that the energy management strategy is crucial for improving the fuel economy of the HEVs. Therefore, the strengths and the limitations of dynamic programming (DP) global optimization strategy and adaptive equivalent consumption minimization strategy (ECMS) for this kind of powertrain system under new European driving cycle (NEDC) and federal test procedure (FTP75) driving cycles are discussed in this paper. The results of the DP global optimization solution have also been adopted as a reference for evaluating the degree of optimality of real-time controllers. The reference start of charge (SOC) was found to be a very important parameter for the real-time ECMS approach. Thus, an adaptive ECMS approach using the SOC obtained from DP global optimization algorithm as a reference SOC in real-time ECMS control was studied. The study results in this paper may provide some theoretical support for future energy management optimization of a 48-V mild hybrid parallel powertrain system.
