Demand management approaches in services sector and influence on company performance
Authors: Rajani Renu L. , Heggde Githa S. , Kumar Rupesh , Bangwal Deepak 
Published: July 2022

PurposeThe purpose of this paper is to empirically examine the impact of supply chain risks (SCRs) and demand management strategies (DMSs) on the company performance in order to study the use of DMSs in delivering improved results even in the presence of SCRs. The SCRs considered under the study are as follows: demand variability, constrained capacity and quality of services delivery, and competitive performance, customer satisfaction and financial performance are the measures considered for company performance.Design/methodology/approachThis study is based on a survey of 439 businesses in India representing 10 groups of services industries (information technology/IT enabled services, business process outsourcing, IT infrastructure, logistics/transportation, healthcare, hospitality, personal services, consulting, education and training, consumer products and retail), using structural equation modeling (SEM) methods.FindingsThe findings reveal that presence of demand variability risk has significant influence upon the use of demand planning and forecasting, controlling customer arrival during peaks and shifting demand to future. Mismatch of capacity against demand (unused capacity) leads to the use of techniques to influence business during lean periods, thereby resulting in enhanced supply chain (SC) and financial performance. Controlling customer arrival during peaks to shift the demand to lean periods leads to enhanced financial performance. Presence of delivery quality risk does not significantly influence the use of DMS. Also, short-term use of customer and business handling techniques does not exert significant influence on company performance.Research limitations/implicationsThe study has limitations as follows: (1) respondents are primarily from India while representing global organizations, (2) process/service redesign to relieve capacity as a DMS is not considered and (3) discussion on capacity management strategies (CMSs) is also excluded.Practical implicationsSC managers can be resourceful in shifting the peak demand to future with the application of techniques to control customer arrival during peaks. The managers can also help enhance business by influencing business through offers, incentives and promotions during lean periods to use available capacity and improve company performance.Originality/valueThis study is one of the first empirical works to explore how presence of SCRs influences the use of DMS and impacts the three types of company performance. The study expands current research on demand management options (DMOs) by linking three dimensions of company performance based on the data collected from ten different groups of service industry.
How educational systems respond to diversity, inclusion and social justice: Disability, power, discipline, territoriality and deterritorialization
Authors: Kikabhai Navin 
Published: July 2022

AbstractThis paper presents a critical examination of a vexed issue relating to how educational systems respond to diversity, inclusion, and social justice. Whilst there are unique factors specific to the various educational sectors; that is, to early years, schools, colleges, higher education and to the life‐long learning sector, this paper explores education and diversity in its broadest sense and recognizes that issues are as much cross‐sector as they are within‐sector. Further still, this paper shifts across disciplinary epistemic boundaries making use of Foucault's tools and the work of Deleuze and Guattari. Given this broader context, this paper primarily traverses the borders of schooling and higher education. It utilizes the notion of scales of justice and draws upon the work of Fraser and explores how this can offer insights into issues not only in relation to redistribution and recognition, but also to representation. It intentionally, draws upon (critical) disability studies literature; and the often‐forgotten discrimination known as disability. It acknowledges the various paradigms and terminological descriptors associated with disabled people, how these are intentionally, I argue, produced and re‐produced, subject to a process of misframing, misrecognition and maldistribution through various territorialized and often segregated educational spaces. In response, this paper offers a reading of dis/ability which moves through theoretical and conceptual understandings and advances the notion of deterritorialization in order to escape, engage and identify larger patterns of inequality. It offers different insights, provides an alternative mapping that can raise different critical questions about disability, also to issues of diversity, inclusion, and social justice.
Fragmenting work: Theoretical contributions and insights for a future of work research and policy agenda
Authors: Grimshaw Damian , Rubery Jill , Cooke Fang Lee , Hebson Gail 
Published: July 2022

AbstractMick Marchington's highly innovative research and writings on ‘Fragmenting Work’ have transformed our understanding of organisations, human resource management (HRM) and the world of work. He led a series of in‐depth case studies of networked organisations—including airport operations, supply chains, multi‐client call centres, public‐private partnerships and information technology outsourcing—and argued for the significance of inter‐organisational networks in directly informing HRM theory and also shaping HRM practice. The resulting highly cited body of published work captured and further developed Mick's intellectual interests in pluralism and complexity in relation to HRM theory. In this article, we reflect on Mick's theoretical contributions and also consider how core theoretical insights derived from the Fragmenting Work research programme can be applied to new questions about the future of work concerning digital platforms, career ladders and global supply chains.

AbstractProtein degradation occurs during the processing of dry‐cured ham, which has important influences on the flavor and quality of products. The aim of this work was to study the degradation kinetics of myofibrillar proteins (MPs) and sarcoplasmic proteins (SPs) extracted from the biceps femoris muscle during the processing of Xuan'en ham. A relationship between protein degradation and the flavor formation was found. During the processing of Xuan'en ham, MPs and SPs were mainly degraded in the salting stage and incipient fermentation. Accompanied by protein degradation, the content of carbonyl group in SPs increased gradually, but in MPs, it first increased and then decreased. Interconversion between sulfhydryl and disulfide bonds was investigated during this processing. Oxidation, degradation, and thermal effects significantly affected the surface hydrophobicity of proteins. More than one hundred volatile compounds have been identified at each stage of ham preparation. Among them, organic acids were the predominant group, followed by hydrocarbons, aldehydes, alcohols, ketones, and esters.
Ewing sarcoma: A pictorial review of typical and atypical locations with reference to the updated 2020 WHO classification system
Authors: Sparreboom Benjamin D , Trautman Jodie , Yaxley Julian 
Published: July 2022

SummaryEwing sarcoma (ES) is a small round cell sarcoma which usually occurs in the paediatric and young adult age groups. This pictorial review briefly discusses and presents the typical skeletal and extraskeletal locations which ES is encountered, including the metadiaphysis of long bones, pelvis, chest wall and paravertebral regions. Five cases of ES in atypical locations are then presented along with an observation of demographic differences between skeletal and extraskeletal ES. These cases include ES arising from the metatarsal, scapula, breast, intracranial soft tissue and the paranasal sinuses. Presenting symptoms, treatment approach and prognosis are highly variable depending on the location; and multimodal imaging is centrepiece in the management process. Management usually includes any combination of chemotherapy, radiotherapy and surgery. The WHO classification system was updated in 2020 to include some of the rare genetic subtypes of ES. One such case of the BCOR subtype is demonstrated in this review and occurs in an atypical location. Whether these subtypes have distinct radiological features or a propensity to occur in atypical locations is an area for further research.

Published: July 2022

AbstractMethamphetamine use is surging globally as a cause of morbidity and mortality. Treatment is typically sought in early abstinence, when craving and depressive symptoms are intense, contributing to relapse and poor outcomes. To advance an understanding of this problem and identify therapeutic targets, we conducted a retrospective analysis of brain structure in 89 adults with Methamphetamine Use Disorder who were in early abstinence and 89 healthy controls. Unlike most prior research, the participants did not significantly differ in age, sex and recent use of alcohol and tobacco (p‐values ≥ 0.400). We analysed thickness across the entire cerebral cortex by fitting a general linear model to identify differences between groups. Follow‐up regressions were performed to determine whether cortical thickness in regions showing group differences was related to craving, measured on a visual analogue scale, or to the Beck Depression Inventory score. Participants in early methamphetamine abstinence (M ± SD = 22.1 ± 25.6 days) exhibited thinner cortex in clusters within bilateral frontal, parietal, temporal, insular, and right cingulate cortices relative to controls (p‐values < 0.001, corrected for multiple comparisons). Unlike craving (β = 0.007, p = 0.947), depressive symptoms were positively correlated with cortical thickness across clusters (β = 0.239, p = 0.030) and with thickness in the anterior cingulate cluster (β = 0.246, p = 0.027) in the methamphetamine‐dependent group. Inasmuch as anterior cingulate pathology predicts response to antidepressants for Major Depressive Disorder, cingulate structure may also identify patients with Methamphetamine Use Disorder who can benefit from antidepressant medication.

AbstractBackgroundSurveys of gender diversity in editorial boards of journals have been conducted in several disciplines, but not in andrology.ObjectivesThe present study was designed to investigate the gender distribution of editorial boards of andrology journals.MethodsA total of eight andrology journals were included in the study, and the gender information and geographical location of editors were identified based on the information obtained from the Internet.ResultsA total of 382 editors’ gender information was confirmed. Women made up 1 of the 9 editors‐in‐chief (11.1%), 13 of the 68 deputy/associate editors (19.1%), 37 of the 270 editorial/advisory board members (13.7%) and 0 of the 35 other types of editors (0%). There was no significant difference in the journal impact factor between male and female editors‐in‐chief (3.060 ± 1.274 vs 3.842), and no significant association was found between impact factor and the proportion of female editor (Spearman'sr = −0.204,P = 0.629).Discussion and conclusionAndrology‐related journals lacked adequate gender diversity, not all journals reserved reasonable editorial positions for women. Besides, increased impact factor did not bring additional gender bias. Women should be given more reasonable seats to improve gender diversity in andrology‐related journals.

AbstractBackgroundThe widespread use of ultrasonography has led to an increased number of incidentally detected small non‐palpable lesions, with Leydig cell tumours representing the majority of them.ObjectivesThe ultrasonography, real‐time elastography and contrast‐enhanced ultrasonography features of a large series of non‐palpable testicular lesions were evaluated, focusing on the differences between Leydig cell tumours and other testicular masses.Materials and methodsOf the 4679 testicular ultrasonography examinations performed at the Authors’ Institution between January 2009 and December 2018, 78 patients (1.7%) were incidentally diagnosed with at least one non‐palpable lesion and were enrolled. Thirteen patients (16.6%) declined surgery and were thus excluded. The remaining 65 underwent surgical resection with frozen section analysis. The conventional ultrasonography, colour Doppler, real‐time elastography and contrast‐enhanced ultrasonography were performed by a radiologist having more than 10 years of experience. Demographic and clinical data were collected.ResultsLeydig cell tumours were detected in 32 patients, being the most frequent benign tumours (49.2%); of the non‐Leydig cell tumours, 25 patients had malignant tumours, five non‐neoplastic lesions and three other benign tumours. The Leydig cell tumour group had mostly infertility problems whereas the non‐Leydig cell tumour group frequently experienced pain (p < 0.001). Leydig cell tumours were all hypoechoic (32/32, 100%; p = 0.002), more frequently presented with well‐defined margins compared to non‐Leydig cell tumours (30/32, 93.8% vs. 19/33, 57.6%; p = 0.001) and tended to be smaller than non‐Leydig cell tumours (5.3 mm [standard deviation 2.7 mm] vs. 10.6 mm [standard deviation 3.8 mm], respectively; p < 0.001). The vascular pattern characterised by the rapid wash‐in followed by the delayed wash‐out observed during contrast‐enhanced ultrasonography was significantly associated with the Leydig cell tumour histological diagnosis, even at multivariate analysis (odds ratio 480.5, p < 0.001), and yielded a high diagnostic accuracy (area under the receiver operating characteristic curve 0.954, 95% confidence interval 0.903–1).DiscussionContrast‐enhanced ultrasonography demonstrated high diagnostic accuracy in identifying benign testicular lesions, such as Leydig cell tumours; they are the most common non‐palpable tumours detected in infertile men and may benefit from enucleation.

AbstractIntroductionVaginal reconstruction using the posterior vaginal wall is required following radical cystectomy in women with resection of the uterus, adnexa, and anterior vaginal wall. Roll closure and clamshell closure are two widely known techniques. Of these, clamshell closure is recommended because roll closure has a high likelihood of breakdown or a resultant canal that is too narrow for sexual intercourse. In clamshell closure, however, folding the posterior vaginal wall anteriorly can be difficult. Therefore, we devised Mercedes‐Benz closure, in which the vaginal wall is sutured from three directions to form a Mercedes‐Benz shape, for anastomosis without tension on the vaginal wall. The present study was performed to investigate the efficacy of this alternative surgical technique for vaginal reconstruction.MethodsTwenty‐six patients who underwent vaginal reconstruction following robot‐assisted radical cystectomy were divided into two groups: 15 underwent clamshell closure and 11 underwent Mercedes‐Benz closure. The patients' characteristics and surgical outcomes were compared between the two groups.ResultsThere were no significant differences in clinical characteristics, including age, body mass index, and prior abdominal surgery between the two groups. The median vaginal reconstruction time tended to be longer in the Mercedes‐Benz closure group than in the clamshell closure group (35.0 vs. 27.0 min, p = 0.102). No complications associated with vaginal reconstruction were identified.ConclusionThe surgical outcomes were comparable between Mercedes‐Benz closure and clamshell closure. If vaginal reconstruction with clamshell closure is difficult, Mercedes‐Benz closure is a valuable alternative technique.

AbstractAimIn this study, we tested plant community‐based management methods to reduce the abundance of the invasive native plant Jacobaea aquatica (marsh ragwort). As J. aquatica mainly occurs in species‐rich wet grasslands, our aim was to define management measures that do not reduce the conservation value of the resident communities.LocationData were collected from 20 independent sites which varied in productivity and management intensity across the pre‐alpine Allgäu region (South Germany).MethodsWe monitored effects of temporary abandonment and decreased mowing intensity in very low‐ and low‐productive sites, as well as of decreased mowing and fertilization at moderately productive sites. Abundances of J. aquatica and the co‐occurring species were recorded at start and end of two experiments (2018–2021: very low‐ and low‐productive conservation grasslands; 2017–2020: moderately productive agricultural grasslands), while functional traits data of all species were gathered from the literature and specific databases. Generalized linear mixed‐effects models (GLMMs) were used to analyse the effects of management intensity on the abundance of J. aquatica, functional diversity and species richness of the resident communities.ResultsAt all productivity levels, the abundance of J. aquatica declined under reduced management. Changes in community composition and species richness of the resident community were less pronounced than the reduction of J. aquatica, but species richness declined under lowest management intensities. Thus, moderate reduction in management intensity provided the most benefits in terms of reduction of J. aquatica, and maintenance of species richness and composition of the resident plant community.ConclusionsReducing management intensity in wet grasslands decreases the abundance of J. aquatica and thus is a suitable method to control this species. As plant community responses were only partially consistent, management plans must account for the productivity of invaded sites. To avoid negative effects on grassland biodiversity, only moderate suppression of J. aquatica is recommended.
Incorporating teacher intelligence into digital games: An expert system‐guided self‐regulated learning approach to promoting EFL students' performance in digital gaming contexts

Published: July 2022

AbstractIn recent years, several studies have reported the potential of employing digital games in EFL (English as Foreign Language) courses to promote students' learning motivation. However, scholars have pointed out that students generally lack self‐learning ability, which is the key to the success of learning a foreign language. Therefore, it is crucial to foster students' self‐learning ability during the game‐based learning process. In this study, an expert system was developed to facilitate self‐regulated learning in digital game‐based learning contexts. To evaluate the effectiveness of the proposed approach, a quasi‐experimental design was employed in a university English course. The experimental group students learned with the self‐regulated English vocabulary game (SR‐EVG) approach, while the control group students learned with the conventional English vocabulary game (C‐EVG) approach. The experimental results indicated that the use of the SR‐EVG approach could improve learners' English vocabulary achievement and self‐regulation compared with the C‐EVG approach without increasing students' English learning anxiety. Moreover, through qualitative interviews, it was found that students who used the SR‐EVG approach would focus on their learning due to goal‐setting in the game and would pay more attention to the learning strategies they used.Practitioner notesWhat is already known about this topic

Digital game‐based learning situates students in a realistic situational environment, enabling students to learn by experiencing and interacting with the situations.
Without appropriate scaffolding during digital game‐based learning, students may become overly focused on the game, or perform many non‐learning behaviors
Self‐regulated learning refers to students’ ability to learn on their own via goal setting, strategic planning, self‐monitoring, and self‐adjustment.
What this paper adds

An expert system‐guided self‐regulated learning approach was proposed to facilitate EFL students’ performance in digital gaming contexts
Due to goal‐setting step, students using the proposed approach would focus on their learning and pay more attention to the learning strategies they used.
Implications for practice and/or policy

It is potentially worth using the expert system‐guided self‐regulated learning approach in EFL training to facilitate students’ performances and perceptions.
The proposed approach can further analyze and compare the students’ gaming and learning behaviors in the digital gaming contexts.
