Hotel social media marketing: a study on message strategy and its effectiveness
Authors: Leung Xi Y. , Bai Billy , Erdem Mehmet 
Published: July 2017

Purpose
The purpose of this study is to develop a typology of social media messages to compare the effectiveness of different message strategies.

Design/methodology/approach
In total, 1,837 messages from 12 hotel brand Facebook pages were content-analyzed. Applying both correspondence analysis and multivariate analysis of variance, the study compared message strategy across hotel-scale levels and explored the effectiveness of different message strategies.

Findings
A typology of four-type message format and six-type message content was developed. The picture message was the best message format. Product, brand and involvement messages were shown to be more effective than information, reward and promotion messages. Promotion message was the least effective message content type.

Research limitations/implications
The major limitation of this study is the generalizability owing to the sample selection process. There is also the limitation on exclusion of control variables, selection of the three effectiveness measures and evolving social media technology.

Practical implications
The typology of Facebook message strategy developed in the study provided guidelines for hotel marketers to create messages on Facebook pages and track effectiveness. Hotels should also take full advantage of the picture format and product, brand and involvement contents.

Originality/value
This study created a new typology of social media message strategy consisting of two dimensions. It also provided empirical evidence to support the application of message strategy theory in the hotel social media marketing area.
Asset liability management and the euro crisis
Authors: Rodriguez Gonzalez Miguel , Kunze Frederik , Schwarzbach Christoph , Dieng Christoph 
Published: July 2017

PurposeThis paper aims to investigate the long-term relationships of long-term European Monetary Union (EMU) government bond yields. From an asset managers’ or risk managers’ perspective during the euro crisis, the relevance of sovereign credit and redenomination risk became a major issue. Furthermore, it has to be differentiated between core and non-core EMU member countries.Design/methodology/approachMethods of applied time series analysis are used to investigate EMU government bond yields and EMU government bond yield spreads for Spain, Italy, The Netherlands, Austria and Germany. Both standard unit root testing procedures and breakpoint unit root tests are used to examine cointegrating relationships and structural changes in these relationships.FindingsThe empirical results deliver clear evidence for structural shifts in the long-term relationship between German and the two non-core EMU countries (Italy and Spain). The timing of the breaks coincides with the timing of the euro crisis. On the contrary, the results for Austria and The Netherlands are different from the findings for the two non-core countries.Research limitations/implicationsOne major limitation of the study is the limited availability of data regarding to the reaction of asset managers or risk managers to the euro crisis. Especially in the context of the discussion with regard to the relevant risk-free rate for investors, this strand of research is relatively new.Practical implicationsA deeper understanding of changes in the long-term relationship between government bond yields and the re-emergence of redenomination risk is important for asset managers and risk managers in the financial services industry. This is especially true for German life insurers.Originality/valueThe study provides various empirical contributions to the literature on the euro crisis and sovereign credit risk. First, previous results with regard to the structural changes in the long-term relationship between German and Spanish, German and Italian, German and Austrian as well as Germany and Dutch government bond yields are confirmed using unit root breakpoint tests. Second, investigating the autoregressive coefficient and the timing of the breaks delivers evidence that non-core countries have been more exposed to the fear of redenomination risk. Third, we raise the question which risk free interest rate is relevant for the affected countries.
Exploring the relationship between macroeconomic indicators and sovereign credit default swap in Pakistan
Authors: Rashid Abdul , Ahmad Farooq , Yasmin Ammara 
Published: July 2017

Purpose
This paper aims to empirically examine the long- and short-run relationship between macroeconomic indicators (exchange rates, interest rates, exports, imports, foreign reserves and the rate of inflation) and sovereign credit default swap (SCDS) spreads for Pakistan.

Design/methodology/approach
The authors apply the autoregressive distributed lag (ARDL) model to explore the level relationship between the macroeconomic variables and SCDS spreads. The error correction model is estimated to examine the short-run effects of the underlying macroeconomic variables on SCDS spreads. Finally, the long-run estimates are obtained in the ARDL framework. The study uses monthly data covering the period January 2001-February 2015.

Findings
The results indicate that there is a significant long-run relationship between the macroeconomic indicators and SCDS spreads. The estimated long-run coefficients reveal that both the interest rate and foreign exchange reserves are significantly and negatively, whereas imports and the rate of inflation are positively related to SCDS spreads. Yet, the results suggest that the exchange rate and exports do not have any significant long-run impact on SCDS spreads. The findings regarding the short-run relationship indicate that the exchange rate, imports and the rate of inflation are positively, whereas the interest rate and exports are negatively related to SCDS spreads.

Practical implications
The results suggest that State Bank of Pakistan should design monetary and foreign exchange rate polices to minimize unwanted variations in the exchange rate to reduce SCDS spreads. The results also suggest that it is incumbent to Pakistan Government to improve the balance of payments to reduce SCDS spreads. The findings also suggest that the inflation targeting policy can also help in reducing SCDS spreads.

Originality/value
This is the first study to examine the empirical determinants of SCDS spreads for Pakistan. Second, it estimates the short- and long-run effects in the ARDL framework. Third, it considers both internal and external empirical determinants of SCDS spreads.

“Work with me”: service users’ perspectives on shared decision making in mental health
Authors: Castillo Heather , Ramon Shulamit 
Published: July 2017

Purpose
While shared decision making (SDM) in general health has proven effectiveness, it has received far less attention within mental health practice with a disconnection between policy and ideals. The purpose of this paper to review existing developments, contemporary challenges, and evidence regarding SDM in mental health with a particular focus on the perspectives of service users.

Design/methodology/approach
This is a review of international papers analysed using narrative synthesis of relevant data bases.

Findings
The review shows significant barriers to the utilisation of SDM including ethical and legal frameworks, accountability and risk. The medical model of psychiatry and diagnostic stigma also contributes to a lack of professional acknowledgement of service user expertise. Service users experience an imbalance of power and feel they lack choices, being “done to” rather than “worked with”.

Practical implications
The paper also presents perspectives about how barriers can be overcome, and service users enabled to take back power and acknowledge their own expertise.

Originality/value
This review is the first with a particular focus on the perspectives of service users and SDM.
Shared decision making within the context of recovery-oriented care
Authors: Davidson Larry , Tondora Janis , Pavlo Anthony J. , Stanhope Victoria 
Published: July 2017

Purpose
The purpose of this paper is to consider the role of shared decision making (SDM) as one component of recovery-oriented care.

Design/methodology/approach
This paper is conceptual and reviews the literature relevant to recovery-oriented care, person-centered recovery planning (PCRP), and SDM.

Findings
To the degree to which SDM offers tools for sharing useful information about treatment options with service users and family members or other loved ones, it can be considered a valuable addition to the recovery-oriented armamentarium. It is important to emphasize, though, that recovery-oriented practice has a broader focus on the person’s overall life in the community and is not limited to formal treatments or other professionally delivered interventions. Within the more holistic context of recovery, SDM regarding such interventions is only one tool among many, which needs to be integrated within an overall PCRP process. More emphasis is given within the recovery-oriented care to activating and equipping persons for exercising self-care and for pursuing a life they have reason to value, and the nature of the relationships required to promote such processes will be identified. In describing the nature of these relationships, it will become evident that decision making is only one of many processes that need to be shared between persons in recovery and those who accept responsibility for promoting and supporting that person’s recovery.

Originality/value
By viewing SDM within the context of recovery, this paper provides a framework that can assist in the implementation of SDM in routine mental health care.
Multinational franchise entry and institutional quality: evidence from Mexican cities
Authors: Fakos Alexandros , Merino Maria 
Published: July 2017

PurposeThe purpose of this paper is to document the extensive heterogeneity in institutions within countries and investigate which institutional factors are the most relevant for international brands.Design/methodology/approachThe paper analyzes the entry patterns of three global fast-food franchise networks in 78 Mexican cities using discrete outcome models and ordered probit in particular. To summarize the quantitative importance of the results, the analysis includes also log-linear regressions with Heckman correction for the city observations without franchise presence.FindingsInstitutional factors are critical for an international franchisor in the decision to enter a new market. The most important institutional quality proxy for franchise entry is the rate of formal employment. The more the informal employment in a city, the lower the number of franchised stores and the lower the probability of brand presence in the city.Research limitations/implicationsOnly three fast-food franchises are included in the paper, which limits the generalization of the results beyond the sector and Mexico. Another limitation of the methodology of this paper is that the authors estimate the effect of institutions on multinational franchise entry conditioning on market size. The issue here is that if institutions increase gross domestic product (GDP) per capita, then the demand for multinational franchises also increases. Such an effect cannot be captured if we condition on market size in our econometric models. This is particularly important for policy-makers aiming to quantify costs and benefits of reforms but not an important consideration for practitioners who might take institutions as given and are mainly interested in entry strategies that maximize profitability.Practical implicationsInstitutional variables, and not only market factors, are critical to understand the entry decision of global franchisors in Mexico. In particular, the extent of informality is relevant in explaining the store location. It is necessary to understand how managers value the quality of institutions and which dimensions are most important for multinationals. In addition, the analysis should be conducted both at the national and sub-national level, given that within-country heterogeneity is prevalent in emerging markets.Social implicationsCities must reinforce and communicate their institutional quality to attract foreign investment by franchises in particular.Originality/valueWe test several dimensions of institutional quality at the urban level as determinants of multinationals? decision to enter a city in a foreign market. We use novel administrative data at the municipality level and we employ econometric model that takes into account the discreetness of entry data and the fact that there are cities with no franchise presence. We control for sample selection, which comes from the zero number of stores in some city observations in the regressions.
Optimal foraging by herbivores maintains polymorphism in defence in a natural plant population
Authors: Sato Yasuhiro , Ito Koichi , Kudoh Hiroshi 
Published: July 2017

Abstract

Many species of plants and animals exhibit polymorphism for defensive traits. Adaptive foraging by natural enemies has long been hypothesized to maintain such polymorphism, but this has not been clearly demonstrated in a natural prey or host population.

The purpose of this study was to address whether the brassica leaf beetle Phaedon brassicae promotes the maintenance of defence polymorphism in the trichome‐producing (hairy) and trichomeless (glabrous) morphs of Arabidopsis halleri subsp. gemmifera. Here, we modelled foraging behaviours of herbivores and demography of the host plant. Then, we estimated the model parameters based on the likelihood of observed data from a natural A. halleri population.

The patterns of leaf damage to hairy and glabrous plants were well explained when we presumed the optimal diet choice (ODC) by P. brassicae. The observed dynamics in the plant number and morph‐frequency were well supported by the model with the estimated parameter values. Our numerical analysis showed that the ODC by P. brassicae caused a negative frequency‐dependent selection on trichrome dimorphism. The coexistence of two morphs was allowed over a wide range of herbivory pressure and the cost of defence.

These results indicate that the ODC by P. brassicae contributes to the coexistence of hairy and glabrous A. halleri. While species interaction and stochastic dispersal are both involved in polymorphism dynamics in the field, our findings suggest that the role of consumer behaviours in the maintenance of defence polymorphism may be more important than currently appreciated.

Root elemental composition in Chinese forests: Implications for biogeochemical niche differentiation
Authors: Zhao Ning , Liu Huiming , Wang Qiufeng , Wang Ruili , Xu Zhiwei , Jiao Cuicui , Zhu Jianxing , Yu Guirui , He Nianpeng 
Published: July 2017

Abstract

Trait‐based community analysis provides a new approach to integrate functional ecology with community ecology. However, our understanding of the linkages between root chemical traits and community chemical diversity and assembly is still in its infancy.

Environmental filtering and niche differentiation are two opposite driving forces of community assembly based on deterministic niche processes. We hypothesize that environmental filtering is a strong driver of root chemical assembly at a large spatial scale, whereas biogeochemical niche differentiation drives root chemical traits divergence among co‐occurring species at site scale.

We analysed the concentrations of 15 elements in the fine roots of 281 species across five forest types of China. Discriminant analysis was used to measure the degree of similarity of root chemical traits at the community level and biogeochemical niche differentiation at the species level.

Root chemical traits at the community level showed a systematic shift along environmental gradients. The growth rate‐related dimension represented by root P and Ca was the most important niche dimension associated with community root chemical assembly, driven by large‐scale environmental filters, particularly soils and climate. Biogeochemical niche differentiation of co‐occurring species could be a consequence of reducing nutrient competition, especially the competition for nitrogen.

Root chemical traits provide a new dimension for assessing the functional niche and may help improve our understanding of the underlying mechanisms of root chemical assembly from the local to the biome scale.

Shorter juvenile telomere length is associated with higher survival to spawning in migratory Atlantic salmon
Authors: McLennan Darryl , Armstrong John D. , Stewart David C. , Mckelvey Simon , Boner Winnie , Monaghan Pat , Metcalfe Neil B. 
Published: July 2017

Abstract

The risk of mortality associated with a long‐distance migration will depend on an animal's physiological state, as well as the prevailing ecological conditions. Here, we assess whether juvenile telomere length, which in endotherms has been shown to be a biomarker of physiological state and expected life span, predicts whether wild Atlantic salmon Salmo salar successfully complete their marine migration.

Over 1,800 juvenile fish were trapped, measured, passive integrated transponder tagged and a tissue biopsy taken when migrating as juveniles down‐river towards the sea. Survivors of the marine phase of the life cycle were then re‐trapped and re‐sampled when returning to the river to spawn as sexually mature adults, 1.5–2.5 years later. Most individuals experienced a reduction in telomere length during the marine migratory phase of their life cycle. While the relative rate of telomere loss was greater in males than females, telomere loss was unrelated to growth at sea.

Contrary to expectations, salmon that had the shortest telomeres at the time of the outward migration had the greatest probability of surviving through to the return migration. This effect, independent of body size, may indicate a trade‐off between investment in readiness for marine life (which favours high glucocorticoid levels, known to increase telomere attrition in other vertebrate species) and investment in telomere maintenance. Survival was also significantly influenced by the seasonal timing of outward migration, with the fish migrating downstream earliest in the spring having the highest probability of return.

This study reveals that telomere length is associated with survival, although in ways that contrast with patterns seen in endotherms. This illustrates that while telomeres may be universally important for chromosome protection, the potential for telomere dynamics to predict performance may vary across taxa.

Published: July 2017

SummaryIntroductionParasympathetic dysfunction may play a role in the genesis of arrhythmias in Chagas disease.AimThis study evaluates the acute effects of pyridostigmine (PYR), a reversible cholinesterase inhibitor, on the occurrence of arrhythmias in patients with Chagas cardiac disease.MethodFollowing a double‐blind, randomized, placebo‐controlled, cross‐over protocol, 17 patients (age 50±2 years) with Chagas cardiac disease type B underwent 24‐hour Holter recordings after oral administration of either pyridostigmine bromide (45 mg, 3 times/day) or placebo (PLA).ResultsPyridostigmine reduced the 24‐hours incidence (median [25%‐75%]) of premature ventricular beats—PLA: 2998 (1920‐4870), PYR: 2359 (940‐3253), P=.044; ventricular couplets—PLA: 84 (15‐159), PYR: 33 (6‐94), P=.046. Although the total number of nonsustained ventricular tachycardia in the entire group was not different (P=.19) between PLA (1 [0‐8]) and PYR (0 [0‐4]), there were fewer episodes under PYR in 72% of the patients presenting this type of arrhythmia (P=.033).ConclusionAcute administration of pyridostigmine reduced the incidence of nonsustained ventricular arrhythmias in patients with Chagas cardiac disease. Further studies that address the use of pyridostigmine by patients with Chagas cardiac disease under a more prolonged follow‐up are warranted.
