Short-Term Study Abroad: An Exploratory View of Business Student Outcomes

Acknowledging the importance of fostering global perspectives in students, business educators stress the role that international study plays in increasing interpersonal skills, and broadening knowledge of global business practices. Traditionally offered as semester- or year-long programs, today\u27s programs are more often short-term in nature, raising questions about student outcomes of abbreviated tours. This longitudinal study of students who participated over a nine-year period examines the benefits and limitations of short-term tours. Results suggest that schools of business give careful consideration to desired student outcomes, learning objectives and how these might best be accomplished if delivered in a compressed time frame

Open Vesicocalicostomy for the Management of Transplant Ureteral Stricture

A 59-year-old male developed a proximal stricture of his transplant ureter ten years after a living donor renal transplant. Endoscopic management was unsuccessful, and the patient was temporized with percutaneous nephrostomy tubes for months. Eventually, it became clear he would require surgical revision. Intraoperatively, complete fibrosis of the renal hilum, and intrarenal location of the pelvis precluded the planned pyelovesicostomy. A successful open vesicocalicostomy was performed, anastomosing a bladder flap to a lower pole calix. The patient remains recurrence free after 6 months of follow-up

Labour after Land Reform: The Precarious Livelihoods of Former Farmworkers in Zimbabwe

What happens to labour when major redistributive land reform restructures a system of settler colonial agriculture? This article examines the livelihoods of former farmworkers on large‐scale commercial farms who still live in farm compounds after Zimbabwe's land reform. Through a mix of surveys and in‐depth biographical interviews, four different types of livelihood are identified, centred on differences in land access. These show how diverse, but often precarious, livelihoods are being carved out, representing the ‘fragmented classes of labour’ in a restructured agrarian economy. The analysis highlights the tensions between gaining new freedoms, notably through access to land, and being subject to new livelihood vulnerabilities. The findings are discussed in relation to wider questions about the informalization of the economy and the role of labour and employment in a post‐settler agrarian economy, where the old ‘farmworker’ label no longer applies

Degeneracies in trapped two-component Fermi gases

We report on previously unobserved inter-system degeneracies in two-component equal-mass Fermi gases with interspecies zero-range interactions under isotropic harmonic confinement. Over the past 10 years, two-component Fermi gases consisting of $n_1$ spin-up and $n_2$ spin-down atoms with interspecies zero-range interactions have become a paradigm for modeling condensed matter systems, nuclear matter and neutron matter. We show that the eigen energies of the $(n_1+1,n_2-1)$ system are degenerate with the eigen energies of the $(n_1,n_2)$ system for any s-wave scattering length $a_s$, including infinitely large, positive and negative $a_s$. The existence of the inter-system degeneracies is demonstrated explicitly for few-body systems with $n_1+n_2=4, 5$ and 6. The degeneracies and associated symmetries are explained within a group theoretical framework.Comment: 5 pages with 4 figures + 5 pages of supplemental materia

Citizens and Condemnation: Strategic Uses of International Human Rights Pressure in Authoritarian States

Governments with strict control over the information that their citizens hear from foreign sources are regular targets of human rights pressure, but we know little about how this information matters in the domestic realm. I argue that authoritarian regimes strategically pass on certain types of external pressure to their public to “internationalize” human rights violations, making citizens view human rights in terms of defending their nation internationally rather than in terms of individual violations, and making them more likely to be satisfied with their government’s behavior. I find strong support for this model through statistical analysis of Chinese state media reports of external human rights pressure and a survey experiment on Chinese citizens’ responses to pressure on women’s rights. This analysis demonstrates that authoritarian regimes may be able to manipulate international human rights diplomacy to help them retain the support of their population while suppressing their human rights

Corporate governance and financial constraints on strategic turnarounds

The paper extends the Robbins and Pearce (1992) two-stage turnaround response model to include governance factors. In addition to the retrenchment and recovery, the paper proposes the addition of a realignment stage, referring specifically to the re-alignment of expectations of principal and agent groups. The realignment stage imposes a threshold that must be crossed before the retrenchment and hence recovery stage can be entered. Crossing this threshold is problematic to the extent that the interests of governance-stakeholder groups diverge in a crisis situation. The severity of the crisis impacts on the bases of strategy contingent asset valuation leading to the fragmentation of stakeholder interests. In some cases the consequence may be that management are prevented from carrying out turnarounds by governance constraints. The paper uses a case study to illustrate these dynamics, and like the Robbins and Pearce study, it focuses on the textile industry. A longitudinal approach is used to show the impact of the removal of governance constraints. The empirical evidence suggests that such financial constraints become less serious to the extent that there is a functioning market for corporate control. Building on governance research and turnaround literature, the paper also outlines the general case necessary and sufficient conditions for successful turnarounds

The Paradox of Power in CSR: A Case Study on Implementation

Purpose Although current literature assumes positive outcomes for stakeholders resulting from an increase in power associated with CSR, this research suggests that this increase can lead to conflict within organizations, resulting in almost complete inactivity on CSR. Methods A single in-depth case study, focusing on power as an embedded concept. Results Empirical evidence is used to demonstrate how some actors use CSR to improve their own positions within an organization. Resource dependence theory is used to highlight why this may be a more significant concern for CSR. Conclusions Increasing power for CSR has the potential to offer actors associated with it increased personal power, and thus can attract opportunistic actors with little interest in realizing the benefits of CSR for the company and its stakeholders. Thus power can be an impediment to furthering CSR strategy and activities at the individual and organizational level

Strategy revision opportunities and collusion

This paper studies whether and how strategy revision opportunities affect levels of collusion in indefinitely repeated two-player games. Consistent with standard theory, we find that such opportunities do not affect strategy choices, or collusion levels, if the game is of strategic substitutes. In games of strategic complements, by contrast, revision opportunities lead to more collusion. We discuss alternative explanations for this result

Foundational stigma: place‐based stigma in the age before advanced marginality.

This paper joins the debate on the formation of territorial stigma by uncovering the existence of a form of “foundational stigma” that preceded place-based stigma of the era of advanced marginality. I show that not only were the traces of stigma present prior to the era of advanced marginality but that these early traces facilitate later forms of stigma by providing the necessary foundations upon which adhesive and detrimental stigma was operationalized. Following a critical discourse analysis approach, this paper examines coverage in the British press of Toxteth, Liverpool between 1900 and 1981 as a paradigmatic case study to show that this primitive stigma existed in three key ways: relating to inter-community strife, to crime, and to substandard housing conditions. These traces of stigma laid the foundations for later forms of stigma based on the presence of the poor, violent, deviant other that would be operationalized by dominant voices during the era of advanced marginality

Transcriptional Profiling of Plasmodium falciparum Parasites from Patients with Severe Malaria Identifies Distinct Low vs. High Parasitemic Clusters

Background: In the past decade, estimates of malaria infections have dropped from 500 million to 225 million per year; likewise, mortality rates have dropped from 3 million to 791,000 per year. However, approximately 90% of these deaths continue to occur in sub-Saharan Africa, and 85% involve children less than 5 years of age. Malaria mortality in children generally results from one or more of the following clinical syndromes: severe anemia, acidosis, and cerebral malaria. Although much is known about the clinical and pathological manifestations of CM, insights into the biology of the malaria parasite, specifically transcription during this manifestation of severe infection, are lacking. Methods and Findings: We collected peripheral blood from children meeting the clinical case definition of cerebral malaria from a cohort in Malawi, examined the patients for the presence or absence of malaria retinopathy, and performed whole genome transcriptional profiling for Plasmodium falciparum using a custom designed Affymetrix array. We identified two distinct physiological states that showed highly significant association with the level of parasitemia. We compared both groups of Malawi expression profiles with our previously acquired ex vivo expression profiles of parasites derived from infected patients with mild disease; a large collection of in vitro Plasmodium falciparum life cycle gene expression profiles; and an extensively annotated compendium of expression data from Saccharomyces cerevisiae. The high parasitemia patient group demonstrated a unique biology with elevated expression of Hrd1, a member of endoplasmic reticulum-associated protein degradation system. Conclusions: The presence of a unique high parasitemia state may be indicative of the parasite biology of the clinically recognized hyperparasitemic severe disease syndrome
