Authors: Silva Rodríguez de San Miguel Jorge Alejandro , Lambarry-Vilchis Fernando , Trujillo Flores Mara Maricela 
Published: November 2018

Purpose
The purpose of this paper is to design a model to improve drinking water management in Iztapalapa, Mexico City from the perspective of managers and users of the service.

Design/methodology/approach
The research question was what elements should an integrated drinking water management model contain to improve drinking water management in Iztapalapa, Mexico City? The research design involved a mixed approach under document analysis, application of semi -structured interviews to four managers of drinking water and measuring perceived service quality and user satisfaction in 360 service users. It included concurrent validity and confirmatory factor analysis.

Findings
The integral drinking water management model is a multidimensional factorially confirmed construct, qualitatively conformed by nine management dimensions, four of perceived quality and three of service satisfaction from home users.

Originality/value
The study fills the gap of little research on drinking water from the perspective of managers and users of the service in a valid and reliable way in Iztapalapa, Mexico City, as no similar research has proposed an integral drinking water management model with the variables used in this research. The model can be applied by following the recommendations to improve water management, which contemplates Mexico’s levels of government to reform the regulations that fragments the management, and taking the budget into profitable activities that support the infrastructure and new water harvesting projects.

On the integration of manufacturing strategy: deconstructing Hoshin Kanri
Authors: Thürer Matthias , Maschek Thomas , Fredendall Lawrence , Gianiodis Peter , Stevenson Mark , Deuse Jochen 
Published: November 2018

PurposeThe purpose of this paper is to show that Hoshin Kanri has the potential to integrate the operations strategy literature into a coherent structure. Hoshin Kanri’s planning process is typically described as a top-down cascading of goals, starting with the senior management’s goals and moving to the lowest organizational level. The authors argue that this misrepresents a firm’s actual cognitive processes in practice because it implies reasoning from the effects to the cause, and assumes a direct causal relationship between what the customer wants and what is realizable by the system.Design/methodology/approachThis study is conceptual, based on abductive reasoning and the literature.FindingsThe actual strategic thought process executed in an organization consists of three iterative processes: (i) a translation process that derives the desired customer attributes from customer/stakeholder data, (ii) a process of causal inference that predicts realizable customer attributes from a possible system design and (iii) an integrative process of strategic choices whereby (i) and (ii) are aligned. Each element relies on different cognitive processes (logical relation, causal relation and choice).Research limitations/implicationsBy aligning the thought and planning processes, the competing concepts of manufacturing strategy are integrated into a coherent structure.Practical implicationsDifferent techniques have to be applied for each of the three elements. As each element relies on different cognitive processes (logical relation, causal relation and choice), the use of unifying tools (e.g. in the form of matrices, as often presented in the literature) is inappropriate.Originality/valueThis is the first study to focus on the thought processes underpinning manufacturing strategy.
Work-personal life conflict and burnout in contact centers
Authors: Geraldes Daniela , Madeira Ema , Carvalho Vânia Sofia , Chambel Maria José 
Published: November 2018

PurposeThe purpose of this paper is to analyze the moderating role of affective commitment in the relationship between work-personal life conflict (WPLC) and burnout in the contact center environment.Design/methodology/approachData were obtained through the participation of a sample of Portuguese employees (n=2,055) of a large company in the contact center sector. Data were analyzed using the Process tool.FindingsThe results support the existence of a positive relationship between both dimensions of WPLC (i.e. time and strain) and burnout (i.e. exhaustion and cynicism). Moreover, the study confirms that the affective commitment moderates the relationship between both dimensions of WPLC and cynicism, buffering these relationships.Research limitations/implicationsThe cross-sectional design and the reliance on self-report measures are the main limitations of this study, although no causality was claimed and method biases were controlled.Practical implicationsContact center managers should develop human resources practices that aid employees to conciliate work and life. Furthermore, these work-life balance practices should be used together with high involvement human resources practices that promote employees’ affective commitment.Originality/valueThis study provides evidence for the need to reconceptualize the traditional work-family conflict, stressing the importance of considering the interference between domains of life, especially in sectors that tend to have young employees.
Being and becoming a “good” qualitative researcher? Liminality and the risk of limbo
Authors: Pagan Victoria 
Published: November 2018

PurposeThe purpose of this paper is to re-conceptualise “good” qualitative research by discussing the intersection between “good” qualitative research and different identity states of “good” qualitative researcher. It uses the anthropological concept of liminality and related concept of limbo to help illustrate the implications of this intersection.Design/methodology/approachA reflexive and personal confessional account is provided of the author’s “living in” the liminal transition of the identity states from full-time PhD student to full-time early career researcher, questioning the author’s experiences in relation to others and the implications for the social construction of “good” qualitative research.Findings“Good” qualitative research is not just what to do but how to be. “PhD student” is a defined and temporary transitional liminal identity state. It has a clear point of separation (acceptance and registration of student status) and aggregation (“good” qualitative research signed of through thesis and viva). Contrasting with this is the “early career researcher” identity state, any point of aggregation towards “established researcher” is predicated on the unpredictability of publication and delivering impact indicators.Originality/valueThe paper demonstrates unsettling and in-betweenness of “good” qualitative research intersecting with the experience and composition of being a “good” qualitative researcher in the academy. It is important for debates regarding the qualities of academic development from PhD student to established researcher.
Authenticity in business sustainability
Authors: Mahsud Rubiná , Imanaka Jessica Ludescher , Prussia Gregory E. 
Published: November 2018

PurposeThis paper critiques existing approaches to business sustainability and recommends a new course of action. This paper focuses the critique on sustainable business practices (SBP) and gaining sustainable competitive advantage (SCA), as they have increasingly been the focus of strategy and management scholars.Design/methodology/approachThe relative progress in the strategy and management domains is reviewed with regard to incorporation of concepts such as sustainability, corporate social responsibility and stakeholder theory. The defense industry is explored as a paradigmatic case of inauthentic sustainability.FindingsFindings reveal that existing constructs lack authentic sustainability, largely on account of the tendency of these discourses to privilege select stakeholders in the developed world. Strategic management research needs to evolve further to accommodate a broader, systemic and global focus that will yield authenticity in business sustainability. Mutual benefit for all stakeholders necessitates a paradigm shift in our thinking from competition to collaboration and creation.Practical implicationsWhen SBP and SCA get applied to certain industries, such as defense, they prop up a form of inauthentic sustainability. All global stakeholders must be included in sustainability frameworks, and some businesses, by their very definition, should not be sustained.Social implicationsMutual benefit for all stakeholders necessitates a paradigm shift in people’s thinking from competition to collaboration and creation. This paper suggests that Blue Ocean Strategy (BOS) can provide the requisite direction for future strategy scholarship so as to overcome existing limitations with SPB and SCA.Originality/valueThis paper suggests that BOS can provide the requisite direction for future strategy scholarship so as to overcome existing limitations with SPB and SCA.
A key floral scent component (β‐trans‐bergamotene) drives pollinator preferences independently of pollen rewards in seep monkeyflower

Published: November 2018

AbstractFloral odours play an important role in attracting insect pollinators. Because pollinators visit flowers to obtain pollen and nectar rewards, they should prefer floral odour profiles associated with the highest‐rewarding flowers (honest signals). In previous work, bumblebees exhibited a preference for flowers from outbred over inbredMimulus guttatusplants. Pollen is the only floral reward inM. guttatus, and pollen viability (a reliable indicator of protein content) is reduced in inbred plants. Yet, differences in pollen viability did not explain the observed preferences.In this study, we examined the floral volatile profiles of inbred and outbredM. guttatusto identify inbreeding effects and associations between volatile compounds and the number of viable pollen grains per flower, designated “PRQ” (pollen reward quality). We also conducted pairwise choice tests withBombus impatiensto evaluate the ability of bees to discriminate between odours of rewarding and non‐rewarding flowers and to determine whether bumblebee preferences are explained by differences in the floral odours of inbred and outbred plants.Inbred plants exhibited reduced emission of β‐trans‐bergamotene, the second‐most abundant compound in the volatile blend of outbred plants. Furthermore, pollen and fertile anthers emitted nonadecane. Six other compounds in the floral blend were positively correlated withPRQ. There was no overlap between compounds affected by inbreeding and compounds associated withPRQ.Even when given prior experience foraging onM. guttatus, bumblebees did not distinguish between the floral odours of rewarding and non‐rewarding outbred plants. However, they preferred floral odours from non‐rewarding outbred plants over rewarding inbred plants. Bumblebees without prior experience of flowers preferred volatile blends with higher versus lower amounts of β‐trans‐bergamotene.Taken together, these results suggest that the volatile emissions ofM. guttatusprovide reliable indicators of pollen rewards (potential honest signals), but that the preference of bumblebees for outbred plants is not driven by these cues but rather by a sensory bias for β‐trans‐bergamotene. This may represent a subtle form of deceit‐pollination that allows plants to attract pollinators while minimizing investment in costly rewards.Aplain language summaryis available for this article.

Published: November 2018

AbstractAimWe previously demonstrated that central nervous system (CNS) melanocortin 4 receptors (MC4R) play a key role in regulating blood pressure (BP) in some conditions associated with increased SNS activity, including obesity. In this study, we examined whether activation of CNS MC4R contributes to chronic intermittent hypoxia (CIH)‐induced hypertension and ventilatory responses to hypercapnia.MethodsRats were instrumented with an intracerebroventricular (ICV) cannula in the lateral cerebral ventricle for continuous infusion of MC4R antagonist (SHU‐9119) and telemetry probes for measuring mean arterial pressure (MAP) and heart rate (HR). Untreated and SHU‐9119‐treated rats as well as obese and lean MC4R‐deficient rats were exposed to CIH for 7‐18 consecutive days.ResultsChronic intermittent hypoxia reduced cumulative food intake by 18 ± 5 g while MAP and HR increased by 10 ± 3 mm Hg and 9 ± 5 bpm in untreated rats. SHU‐9119 increased food intake (from 15 ± 1 to 46 ± 3 g) and prevented CIH‐induced reduction in food intake. CIH‐induced hypertension was not attenuated by MC4R antagonism (average increase of 10 ± 1 vs 9 ± 1 mm Hg for untreated and SHU‐9119 treated rats). In obese MC4R‐deficient rats, CIH for 7 days raised BP by 11 ± 4 mm Hg. However, when MC4R‐deficient rats were food restricted to prevent obesity, CIH‐induced hypertension was attenuated by 32%. We also found that MC4R deficiency was associated with impaired ventilatory responses to hypercapnia independently of obesity.ConclusionThese results show that obesity and the CNS melanocortin system interact in complex ways to elevate BP during CIH and that MC4R may be important in the ventilatory responses to hypercapnia.

AbstractThe incidence of secondary perineal hernia (SPH) has increased since the introduction of extralevator abdominoperineal resection and laparoscopic abdominoperineal resection. Currently, laparoscopic mesh repair is the usual procedure. Here, we demonstrate a repair of SPH without mesh that uses the mobilized cecum to cover the pelvic hernial orifice. An 83‐year‐old man complained of discomfort when sitting for long periods. He was status post laparoscopic abdominoperineal resection and was diagnosed with SPH. Hernia repair was performed. After transperitoneal adhesiolysis in the inferior pelvis, the right colon was laparoscopically mobilized, and the pelvic orifice was covered by suturing the cecum to the pelvic brim. The perineal skin was managed with negative pressure wound therapy. The postoperative course was uneventful. There has been no sign of recurrent herniation for 12 months. This method of SPH repair is simple to perform and avoids mesh‐related complications.
Clinical Features Contributing to Cortical Thickness Changes in Chronic Migraine – A Pilot Study
Authors: Woldeamanuel Yohannes W. , DeSouza Danielle D. , Sanjanwala Bharati M. , Cowan Robert P. 
Published: November 2018

ObjectivesThe objectives of this cross‐sectional pilot study were threefold: to identify regions of cortical thickness that differentiate chronic migraine (CM) from controls, to assess group differences in interregional cortical thickness covariance, and to determine group differences in associations between clinical variables and cortical thickness.BackgroundCortical thickness alterations in relation to clinical features have not been adequately explored in CM. Assessment of this relationship can be useful to describe cortical substrates for disease progression in migraine and to identify clinical variables that warrant management emphasis.MethodsThirty CM cases (mean age 40 years; male‐to‐female 1:4) and 30 sex‐matched healthy controls (mean age 40 years) were enrolled. Participants completed self‐administered and standardized questionnaires assessing headache‐related clinical features and common psychological comorbidities. T1‐weighted brain images were acquired on a 3T MRI. A whole‐brain cortical thickness analysis was performed. Additionally, correlations between all brain regions were assessed to examine interregional cortical thickness covariance. Interactions were analyzed to identify clinical variables that were significantly associated with cortical thickness.ResultsThe whole brain cortical thickness analysis revealed no significant differences between CM patients and controls. However, significant associations between clinical features and cortical thickness were observed for the patients only. These associations included the right superior temporal sulcus (R2 = 0.72, P = .001) and the right insula (R2 = 0.71, P = .002) with distinct clinical variables ie, longer history of CM, posttraumatic stress disorder (PTSD), sleep quality, pain self‐efficacy, and somatic symptoms. Higher interregional cortical covariance was found in CM compared to controls (OR = 3.1, CI 2.10–4.56, P < .0001), such that cortical thickness between regions tended to be more correlated in patients, particularly in the temporal and frontal lobes.ConclusionCM patients have significantly greater cortical covariance compared to controls. Cortical thickness in CM patients was predominantly accounted for by CM duration, PTSD, and poor sleep quality, while improved pain self‐efficacy buffered cortical thickness. While it is important to address all CM features and comorbidities, it may be useful to emphasize optimizing the management of certain clinical features that contribute to cortical abnormalities including managing PTSD, early management to shorten duration of CM, and improving pain self‐efficacy and sleep quality.
The reuse of brine to enhance the ripening of marine and freshwater fish resistant to marinating

Published: November 2018

SummaryCold marinades are produced mainly from the Clupeidae fish, because meat of other fish species does not reach a desired level of ripeness in the acid‐salt environment of fresh brine. Hence, this work presents an innovative idea of reusing brine including cathepsins and peptides for marinating cod, salmon, trout, and carp. The extent of marinades ripening improvement depended on fish resistance to the marinating process. The reused brine proved best in improving the ripening of fatty fish (salmon and trout), which were qualified to the first class of resistance to marinating. In the case of cod, the reuse of brine did not elicit a satisfactory improvement in meat ripening. Therefore cod was qualified to the second class of resistance. The reuse of brine resulted in decreased values of lipid oxidation indices (except for cod) and meat hardness, and in increased scores for overall sensory evaluation and total volatile bases nitrogen value.

AbstractThis study was conducted to evaluate the biopreservative potential of Lactobacillus plantarum Lp6SH (Lp6SH), Lactobacillus rhamnosus Yoba (LrYoba) and their cell‐free supernatants (CFS) on whole captured tropical pink shrimps (Penaeus duorarum notialis) during storage at 4°C for 8 days. Shrimps were inoculated with strains Lp6SH, LrYoba, their supernatants, sodium metabisulfite (2%) and stored at 4 ° C for 8 days. Sensory evaluation, physicochemical, and microbiological analyses were performed daily. Lp6SH, CFS of Lp6SH, and CFS of LrYoba were able to prolong the sensory shelf life up to 8 days. The total volatile basic nitrogen (TVBN) concentration was lower than the acceptable value at the end of the storage period. All the treatments reduced the number of total aerobic bacteria and fungi, and maintained the coliforms count for 2 days. Strain Lp6SH reduced the number of Staphylococci for 4 days. Based on the threshold values, the microbiological shelf life of shrimps was between 2 and 6 days at 4°C. L. plantarum Lp6SH and the CFS of L. rhamnosus Yoba could be used as natural preservatives to replace the use of sodium bisulfate in prolonging the microbiological and sensory shelf life of captured whole shrimps.Practical applicationsMicrobial spoilage of raw fresh shrimps and black spots formation constitute substantial economic losses as well as serious public health problem. Due to the harmful effects of chemical preservatives, attention is paid nowadays to the search for fresh shrimp preservation methods that could obviate the use of chemicals and prevent blackspot formation. In this respect, the results of this study supported that Lactobacillus plantarum Lp6SH strain and the cell‐free supernatant of Lactobacillus rhamnosus Yoba are suitable biopreservatives that could be used to increase the safety, prevent melanosis, and extend the sensory shelf life of captured whole shrimps stored under refrigeration. After studies for their application at large scale, the fishermen and food industries can use the bacterial suspension and the cell‐free supernatant as spray or immersion solutions for the treatment of shrimps (or other seafood) prior to freezing.

Published: November 2018

SummaryObjectivesThe aim of the study was to examine whether oral health as an infection focus could mediate disease course in patients with Behçet's disease (BD).MethodsIn the study, oral health of 194 BD patients was examined at baseline and follow‐up periods. The reasons for last dental visits were recorded as tooth extraction or regular control visits/planned treatments at the end of follow‐up period. The Behçet's disease severity score was calculated with higher scores indicating a more severe course. Mediation analysis was carried out to assess the effects of oral health on disease severity score at follow‐up period in the study.ResultsDental and periodontal indices were found to be higher at follow‐up visit compared to those of baseline (P < 0.05). Disease severity score was found to be higher in males (5.3 ± 2.4) compared to females (4.4 ±2.5) in the whole group (P = 0.005). Moreover, patients having tooth extraction at their last dental visit and patients with dental caries had a more severe disease course (5.4 ± 2.4; 5.5 ± 2.5) compared to others (4.2 ± 2.3; 4.4 ± 2.4; P < 0.0001). In multiple mediation analysis, disease severity score was a dependent variable and was directly mediated by male gender (B = −0.8822, P = 0.0145) and indirectly mediated through the presence of dental caries (B = 0.9509 P = 0.0110) and need of tooth extraction (B = 0.8758, P = 0.0128).ConclusionBoth presence of dental caries and need of tooth extraction were observed to be effective mediators for a more severe disease course in BD. Therefore, better oral health should be aimed to eliminate microbial factors, which are a part of pathogenic processes.
