Exploring replenishment in the luxury fashion Italian firms: evidence from case studies
Authors: d'Avolio Elisa , Bandinelli Romeo , Pero Margherita , Rinaldi Rinaldo 
Published: October 2015

Purpose– The purpose of this paper is to investigate how luxury Italian fashion companies manage the replenishment process, and how they leverage supply chain (SC) to be able to match supply and demand of fashion products.Design/methodology/approach– Literature review was the first step performed; then, a case study research has been conducted in order to have a comprehensive view of the real context of luxury Italian fashion companies concerning merchandise planning and replenishment processes. After the sample was individuated, a questionnaire has guided the interviews and then data have been collected. Analysing data has concerned a primary case analysis and then cross-case patterns have been searched. Finally, several variables coherent to the aim of the study have been pinpointed and a framework has been designed.Findings– The paper provides a characterization of the luxury Italian fashion industry concerning merchandise planning constraints and the replenishment processes. To guarantee the flexibility required to match supply and demand when there is a high percentage of seasonal products in the collection, companies leverage on both downstream and upstream SC alignment.Originality/value– The enhancement of performance within the fashion SC is a topic not too much examined in depth, in particular referring to the luxury fashion companies and to the Italian context. Aligning upstream and downstream activities, information sharing between vendor and retailer and securing strategic alliances with the suppliers constitute important steps to reach flexibility and reactivity and to be in step with the market needs. The paper provides valuable insights to companies that are trying to decrease their lost sales and to increase their sell-out and customer service through a review of their SC processes.

Authors: Cavender RayeCarol , Kincade Doris H. 
Published: October 2015

Purpose
– The purpose of this paper is to develop a luxury brand management (LBM) framework that accounts for the changing luxury environment (i.e. heterogeneous consumer populations, operations within markets of varying maturity, need for seamless customer experiences, and Omni-channel retailing). Framework set within this new luxury business environment and environmental phenomena unique to the fashion industry (i.e. fashion adoption, zeitgeist).

Design/methodology/approach
– Case study of leading luxury conglomerate, Louis Vuitton Möet Hennessy (LVMH), combined with in-depth historical review of luxury industry. Primary and secondary data sources yielded thick descriptions of brands in LVMH portfolio and larger luxury industry, in which conglomerate is the predominant organizational structure. Content analysis of data-tracked relationships and emergent patterns. Recontextualization techniques were employed to identify key dimensions of brand management operations for sample company and further explicated indicators, sub-variables, and measurements. Macro and micro dimensions were combined for the final framework.

Findings
– Findings revealed a LBM framework with specific dimensions at the micro or company level that are combined with variables and indicators in the macro-business environment. Strategic management response was also identified as a tool companies can use to synthesize brand management strategies throughout company and remain adaptive to environment.

Originality/value
– Contributes to company-based luxury research. Holistic findings; framework was constructed from the micro-company level within a macro-environmental context, increasing its relevancy for firms. Potential to be employed in strategic brand management decisions of luxury companies, regardless of their corporate structure, size, or age.
Supply chain strategy for companies in the luxury-fashion market
Authors: Castelli Cecilia Maria , Sianesi Andrea 
Published: October 2015

Purpose
– The purpose of this paper is to show how it is possible to take into account the objectives that fashion-luxury companies pursue on the final market (i.e. critical success factors (CSF) – of luxury) and propagate them in the upstream steps of the supply chain (SC) in order to understand how the latter can be aligned to the market.

Design/methodology/approach
– An extensive literature review allowed the identification of SC objectives. Case studies were used in order to asses choices and practices applied along the SC of luxury companies were assessed through in depth case studies; hence, the relationship between choices/practices, SC objectives and luxury CSF was explored.

Findings
– The paper documents that success in the luxury market not only depends on branding and marketing but also on the choices made along the SC, to the point that it is possible to identify some SC choices and practices that support the achievement of luxury CSF.

Research limitations/implications
– The results presented represent a useful guideline and offer some methodological suggestions; however, the precise set of SC objectives have to be tailored on each specific brand, according to the uniqueness that characterizes luxury companies.

Practical implications
– The paper suggests which areas of the SC should be mostly targeted in order to achieve success in the luxury market, also indicating some possible concrete choices.

Originality/value
– The main value of this paper consists in shaping a first explicit connection among the world of luxury as it is perceived by the consumers and the world of the SC.
Firm size and the political cycle premium
Authors: Malone Chris B , Anderson Hamish , Cheng Peng 
Published: October 2015

Purpose
– The purpose of this paper is to use firm-level data to examine whether the political cycle differentially relates to small vs large firms in New Zealand; a country that operates a unicameral political system has a short three-year political term and a right-of-centre stock market premium exists.

Design/methodology/approach
– Using firm-level data from 1972 to 2010, the authors examine monthly returns during right-of-centre National governments and left-of-centre Labour governments. The authors apply Santa Clara and Valkanov (2003) regression analysis approach to examine the political cycle impact on firm returns.

Findings
– Like in the USA, New Zealand’s political cycle premium is driven by small firms; however, the results are opposite. In New Zealand, periods governed by the right of the political spectrum produce significantly higher stock returns than those from the left and this finding is primarily driven by small firms who perform particularly poorly under left-of-centre governments.

Research limitations/implications
– Small firms were relatively heavily affected by the move to an open, deregulated economy; they were also less able to cope with tight monetary conditions, and periods of sharply falling inflation. New Zealand’s three-year political term may encourage newly formed governments to implement relatively fast moving shifts in policy where a more reasoned and steady approach would be warranted.

Originality/value
– This is the first paper to use firm-level data outside of the USA to examine the political cycle impact.
What to expect when you’re electing
Authors: Beyer Scott , Garcia-Feijoo Luis , Jensen Gerry , Johnson Robert R. 
Published: October 2015

Purpose– The purpose of this paper is to analyze security-market returns relative to the political party of the president, the Federal Reserve’s monetary policy, the year of the president’s term, and the state of political gridlock. Contrary to prior studies, which evaluated the influences separately, the authors jointly evaluate these variables.Design/methodology/approach– The analysis supports the notion that security returns are significantly related to shifts in Fed monetary policy, political gridlock, and the year of the presidential term; however, returns are generally invariant to the president’s political party affiliation. Overall, the findings suggest that investors should focus less attention on the party of the president and instead more closely monitor Fed actions.Findings– It appears that political harmony should be welcomed by equity investors, but not debt investors. Finally, regardless of the political outcome, if the past serves as a guide, investors may have to wait until year three of the next presidential term to enjoy the fruits of the current political season.Originality/value– The academic literature is rich with studies that consider the aforementioned political effects and the influence that monetary policy have on the markets. To date, however, these factors have not been jointly considered when examining returns. This paper considers several dimensions of the political landscape – the party of the president, the presence or absence of political gridlock, and the presidential term cycle effect – in conjunction with Fed monetary policy in examining long-term security returns. By examining the relationship between security returns and both political and monetary conditions, the authors provide robust evidence regarding the relationships.
Does the revolving door swing both ways? The value of political connections to US firms
Authors: Houston Reza , Ferris Stephen 
Published: October 2015

Purpose
– The purpose of this paper is to analyze the value of corporate political connections resulting from the revolving door of employment between political office and the for-profit corporation. The authors test whether there is value to firms from political connections provided by the appointment of former politicians to corporate boards or management teams. The authors also test to see if passage through the door in the other direction, from the corporate world to public office, generates value for firms. Do firms whose former employees gain public office earn excess returns following their appointment or election to these positions?

Design/methodology/approach
– The methodology used in this study focusses on an empirical analysis of the political connections of US firms over the sample period 1996-2011. The analysis emphasizes the wealth effects associated with the announcement of hiring former politicians to corporate boards or the gaining of political office by former corporate employees.

Findings
– The authors find that politicians becoming corporate directors is 2.5 times more common than corporate executives gaining public office. The authors determine that industries with extensive government regulation most often hire former politicians. The authors find that the office held by former politicians matters. The authors find that longevity in a cabinet position is important while formal Congressional or Senate leadership positions are not. Surprisingly, the authors determine the longer politicians are out of office, the more value they are able to provide to the firm. Finally, the authors discover that firms which hire former politicians have significantly positive long-term abnormal returns, but firms whose managers enter politics do not.

Originality/value
– This study is highly original in its examination of political connections resulting from door swing in both directions. Further, the analysis of longevity, time out of office, and position held adds to the contributions made by this study.
Tunisian revolution and stock market volatility: evidence from FIEGARCH model
Authors: Jeribi Ahmed , Fakhfekh Mohamed , Jarboui Anis 
Published: October 2015

Purpose– Previously elaborated research works, dealing with the political uncertainty effect on stock market, have been primarily concerned with such political events as terrorist attacks, elections, wars, natural catastrophes and financial crashes. Such little research has been concerned with civil uprisings and revolutionary movements, as crucial sources of political uncertainty. The purpose of this paper is to study the impact of political uncertainty (resulting from the Tunisian Revolution) on the volatility of major sectorial stock indices in the Tunisian Stock Exchange (TSE).Design/methodology/approach– The authors apply the fractionally integrated exponential generalized autoregressive conditional heteroscedasticity model (FIEGARCH), which helps maintain a direct shock-persistence as well as a shock asymmetric volatility measurement. This model is applied to the daily returns relevant to nine sectorial stock indices and to the Tunisian benchmark index (TUNINDEX) with respect to three sub-periods (before, during and follows the Tunisian Revolution).Findings– The reached findings suggest that the shock impact throughout the Revolution period on construction, industries, consumer services, financial services, financial companies indices’ sectorial and the TUNINDEX return volatilities have proven to be permanent, while its persistence on the other indices has been discovered to be transitory. In addition, the achieved results appear to reveal a low leverage effect on all indices. This result seems to be very important since the Tunisian Revolution turns out to have a very important effect on the TSE.Originality/value– The paper’s empirical contribution lies in using the FIEGARCH approach to model the Tunisian sectorial indices’ volatility dynamics, persistence degree and leverage effect. This contribution goes a long way in helping regulators and international investors to further recognize the extent to which political instability does participate in affecting the TSE.
A novel route for ethanol oxidation in the acetogenic bacterium Acetobacterium woodii: the acetaldehyde/ethanol dehydrogenase pathway
Authors: Bertsch Johannes , Siemund Anna Lena , Kremp Florian , Müller Volker 
Published: October 2015

SummaryEthanol is a common substrate for anaerobic microorganisms despite its high redox potential ( etha‐ nol/acetaldehyde = −190mV), which does not allow for NAD+ reduction. How this thermodynamic barrier is overcome is largely unknown. The acetogenic bacterium Acetobacterium woodii can also grow on ethanol. The genome harbours 11 genes encoding putative alcohol dehydrogenases, but only one, adhE, was upregulated during growth on ethanol. The bifunctional acetaldehyde/ethanol dehydrogenase (AdhE) was purified from ethanol‐grown cells. It catalysed the NAD+‐ and CoA‐dependent oxidation of ethanol via acetaldehyde to acetyl‐CoA. The enzyme was regulated by free coenzyme A: in the absence of coenzyme A, the Km value for ethanol was shifted from 3.4 to 40 mM. The alcohol dehydrogenase domain could also oxidize 1‐propanol and 1‐butanol; however, the aldehyde dehydrogenase domain was highly specific for acetaldehyde as substrate. Apparently, the bifunctional AdhE allows for NAD+ reduction by lowering the concentration of acetaldehyde, which makes the first oxidation reaction thermodynamically feasible.
Metagenomic analysis provides insights into functional capacity in a hyperarid desert soil niche community

Published: October 2015

SummaryIn hyperarid ecosystems, macroscopic communities are often restricted to cryptic niches, such as hypoliths (microbial communities found beneath translucent rocks), which are widely distributed in hyperarid desert environments. While hypolithic communities are considered to play a major role in productivity, the functional guilds implicated in these processes remain unclear. Here, we describe the metagenomic sequencing, assembly and analysis of hypolithic microbial communities from the Namib Desert. Taxonomic analyses using Small Subunit phylogenetic markers showed that bacterial phylotypes (93%) dominated the communities, with relatively small proportions of archaea (0.43%) and fungi (5.6%). Refseq‐viral database analysis showed the presence of double stranded DNA viruses (7.8% contigs), dominated by Caudovirales (59.2%). Analysis of functional genes and metabolic pathways revealed that cyanobacteria were primarily responsible for photosynthesis with the presence of multiple copies of genes for both photosystems I and II, with a smaller but significant fraction of proteobacterial anoxic photosystem II genes. Hypolithons demonstrated an extensive genetic capacity for the degradation of phosphonates and mineralization of organic sulphur. Surprisingly, we were unable to show the presence of genes representative of complete nitrogen cycles. Taken together, our analyses suggest an extensive capacity for carbon, phosphate and sulphate cycling but only limited nitrogen biogeochemistry.
Major contribution of the type II beta carbonic anhydrase CanB (Cj0237) to the capnophilic growth phenotype of Campylobacter jejuni
Authors: Al‐Haideri Halah , White Michael A. , Kelly David J. 
Published: October 2015

SummaryCampylobacter jejuni, the leading cause of human bacterial gastroenteritis, requires low environmental oxygen and high carbon dioxide for optimum growth, but the molecular basis for the carbon dioxide requirement is unclear. One factor may be inefficient conversion of gaseous CO2 to bicarbonate, the required substrate of various carboxylases. Two putative carbonic anhydrases (CAs) are encoded in the genome of C. jejuni strain NCTC 11168 (Cj0229 and Cj0237). Here, we show that the deletion of the cj0237 (canB) gene alone prevents growth in complex media at low (1% v/v) CO2 and significantly reduces the growth rate at high (5% v/v) CO2. In minimal media incubated under high CO2, the canB mutant grew on L‐aspartate but not on the key C3 compounds L‐serine, pyruvate and L‐lactate, showing that CanB is crucial in bicarbonate provision for pyruvate carboxylase‐mediated oxaloacetate synthesis. Nevertheless, purified CanB (a dimeric, anion and acetazolamide sensitive, zinc‐containing type II beta‐class enzyme) hydrates CO2 actively only above pH 8 and with a high Km (∼34 mM). At typical cytoplasmic pH values and low CO2, these kinetic properties might limit intracellular bicarbonate availability. Taken together, our data suggest CanB is a major contributor to the capnophilic growth phenotype of C. jejuni.

SummaryInteractions between microorganisms and rocks play an important role in Earth system processes. However, little is known about the molecular capabilities microorganisms require to live in rocky environments. Using a quantitative label‐free proteomics approach, we show that a model bacterium (Cupriavidus metallidurans CH34) can use volcanic rock to satisfy some elemental requirements, resulting in increased rates of cell division in both magnesium‐ and iron‐limited media. However, the rocks also introduced multiple new stresses via chemical changes associated with pH, elemental leaching and surface adsorption of nutrients that were reflected in the proteome. For example, the loss of bioavailable phosphorus was observed and resulted in the upregulation of diverse phosphate limitation proteins, which facilitate increase phosphate uptake and scavenging within the cell. Our results revealed that despite the provision of essential elements, rock chemistry drives complex metabolic reorganization within rock‐dwelling organisms, requiring tight regulation of cellular processes at the protein level. This study advances our ability to identify key microbial responses that enable life to persist in rock environments.

Published: October 2015

ObjectiveTo assess whether, 5 years into the HITECH programs, national data reflect a consistent relationship between EHR adoption and hospital outcomes across three important dimensions of hospital performance.Data Sources/Study SettingSecondary data from the American Hospital Association and CMS (Hospital Compare and EHR Incentive Programs) for nonfederal, acute‐care hospitals (2009–2012).Study DesignWe examined the relationship between EHR adoption and three hospital outcomes (process adherence, patient satisfaction, efficiency) using ordinary least squares models with hospital fixed effects. Time‐related effects were assessed through comparing the impact of EHR adoption pre (2008/2009) versus post (2010/2011) meaningful use and by meaningful use attestation cohort (2011, 2012, 2013, Never). We used a continuous measure of hospital EHR adoption based on the proportion of electronic functions implemented.Data Collection/Extraction MethodsWe created a panel dataset with hospital‐year observations.Principal FindingsHigher levels of EHR adoption were associated with better performance on process adherence (0.147; p < .001) and patient satisfaction (0.118; p < .001), but not efficiency (0.01; p = .78). For all three outcomes, there was a stronger, positive relationship between EHR adoption and performance in 2010/2011 compared to 2008/2009. We found mixed results based on meaningful use attestation cohort.ConclusionsPerformance gains associated with EHR adoption are apparent in more recent years. The large national investment in EHRs appears to be delivering more consistent benefits than indicated by earlier national studies.

Published: October 2015

AbstractIn this study, influence of 3 types of photo‐selective nets (pearl, red and yellow) and a standard black net on marketable yield, fruit quality and bioactive compounds after postharvest storage was investigated. Percentage marketable fruits were higher in green sweet peppers produced under the pearl nets. Fruits produced under the pearl nets showed higher fruit mass, firmness, chlorophyll content, ascorbic acid content, antioxidant scavenging activity after postharvest storage. Red/far red photon ratio under the pearl net could have improved the ascorbic acid content and the antioxidant scavenging activity in green peppers. Green sweet peppers grown under the pearl nets had higher hue values and maintained green color longer. Our results showed the impact of modified light quality on the bioactive compounds of green sweet pepper during postharvest storage.
