Are Third-Party Fundamental Valuations Relevant in Public Company Takeovers?
Authors: Shaffer Matthew
Published: November 2023

In U.S. mergers and acquisitions, target directors are required to consider third-party financial valuations, summarized in a “fairness opinion” before accepting a takeover offer. Critics argue (1) that these valuations are not relevant for public companies, which can assess the desirability of the deal based on the market premium, and (2) that the investment bank providers cater to management by “rationalizing” the deal price rather than providing an independent valuation check. I find that fairness valuations can provide valid information about the target’s value, incremental to its predeal stock price. They can impound expected transaction synergies, unravel rumor-driven stock price runups, and may signal ex ante fundamental mispricing. I also find evidence of the alleged catering, which I distinguish from “legitimate” valuation disagreements. This suggests that third-party fundamental valuation could play a useful role in the governance of public company takeovers, but there are flaws in its current implementation.

Effect Of UV-Assisted Titanium Dioxide (TiO2) Photocatalysis on Viable Airborne Bacteria and Fungi in The Seasoning Powder Industry
Authors: Cakrawati Dewi , Aprilianto Kevin , Faridah Chintya Nur , Utami Kiki Diyah Ayu
Published: November 2023

Titanium dioxide (TiO2) has been known to have anti-microbial activity against fungi, bacteria, and viruses. The application of TiO2 in the membrane attached to the air conditioner was expected to minimize airborne microorganisms. This study contribution to investigate the efficacy of UV-assisted TiO2 photocatalysis in controlling airborne microorganisms in the seasoning powder industry. TiO2 was coated to the non-woven membrane and attached with a UV lamp inside the air conditioner. When the AC was on, the Ti3+ was released into the air. Enumeration of airborne microorganisms was conducted by opening the agar plates for 15 min at several food processing facilities, followed by incubating agar plates for 72 hours at 30 °C. The result shows dry processing facility had the highest number of initial airborne bacteria while the wet production facility had the highest number of initial airborne fungi. Interestingly, the number of airborne microorganisms fluctuated in the packaging facility related to the number of people going inside and outside. On the contrary, the number of airborne microorganisms was deficient in empty rooms, which indicated that the number of airborne microorganisms might be related to people and products. Overall, airborne microorganisms were reduced after 60 min of irradiation. Therefore, it is recommended to irradiate the facilities for 60 min before production start. SEM images and EDAX analysis results show TiO2 was detected after 160 h. However, it was recommended to change the TiO2 membrane after one month. This research was expected to contribute to controlling airborne microorganisms during food production in food processing facilities.

Published: November 2023

This study aimed to investigate the outcomes of open tibia shaft fractures at a level one trauma center in a developing world setting. Specific objectives were to determine the association of time delay to antibiotic administration, surgical debridement, definitive skeletal stabilisation and soft tissue reconstruction, and the development of fracture-related infection (FRI).

A retrospective cohort study included all adult patients with open tibia shaft fractures from July 2014 to June 2016 and January 2018 to December 2019. Patients who were skeletally immature at the time of injury, those with pathological fractures and who did not complete follow-up of at least three months were excluded. Patients were identified from hospital records. Data was captured in Microsoft Excel and analysed using STATISTICA. A Chi-squared was used to detect significant differences between groups.

No association between infection and antibiotic administration was observed when patients were treated within or after 3 hours (p=0.625) or if patients had their first surgical debridement in theatre before or after 24 hours (p=0.259). Patients who waited more than five days for definitive skeletal fixation or soft tissue reconstruction had a significant increase in FRI (OR 4.7, 95% CI 2.0 – 10.9 and OR 4.7, 95% CI 2.0 – 11.0, respectively). Patients who underwent more than two formal debridements had a higher risk of developing FRI (OR 15.6, 95% CI 5.8 – 41.6).

Whilst administration of antibiotics within 3 hours of presentation to the emergency unit had no impact on the development of FRI, time delays in managing open tibia shaft fractures are associated with an increased risk for FRI. Definitive soft tissue reconstruction and skeletal stabilization should not be delayed for more than five days.
SCOLIOSIS SURGERY WEEK: A SOUTH AFRICAN TERTIARY INSTITUTION EXPERIENCE
Authors: Maseko Mmangaliso , Ukunda Freddy
Published: November 2023

Orthopaedic paediatric deformities, globally, are often corrected later than initial identification due to resource constraints (bed availability, investigative modalities, surgical skill set). The study aims to analyse experiences and challenges met with running a flagship scoliosis surgery week in a tertiary public health care facility, with the goal of reducing patient waiting time on the waiting list.

In this retrospective study, patients from an existing deformity correction waiting list were selected for a 5 day scoliosis surgery week. Investigations relevant to clinical findings were carried out and patients were scheduled on a “one patient per day” surgery list. Inclusion criteria was any patient with adolescent idiopathic scoliosis of varying degree that was symptomatic. Exclusion criteria was any other deformity of any age.

Outcomes measured include: Administrative hurdles (obtaining funding, organising ward and ICU beds, getting nursing staff), Surgical challenges (severity of the curve, intraoperative time, approach chosen) and perioperative management (anaesthesia, pain management, cost of equipment) will be looked at to better define the experiences and challenges.

All scheduled surgeries were completed. This meant more cases were carried out than what was done in the last 2 years at the facility combined. Lack of Nursing staff availability and few ICU beds delayed starting cases. Anterior fusion took a shorter surgical time in comparison to posterior and cost far less to carry out owing to deformity severity. Intra and post operative management also varied due to daily changes in theatre staff and a lack of standardized protocols.

Running a scoliosis surgery week helps to lower the waiting time for deformity correction in public health care facilities. Pre organising resources results in more successful outcomes and an increase in the number of cases done over a shorter period.
MICROBIAL CONTAMINATION OF CELLPHONES OF HEALTHCARE WORKERS IN THE ORTHOPAEDIC DEPARTMENT AT A TERTIARY INSTITUTE IN GAUTENG

Published: November 2023

The role that fomites have to play in surgical site infection (SSI) and periprostheitic joint infection (PJI) has been observed and researched in the past. However the role that cellphones play in the transfer of microorganisms from hands to surgical sites and the indiscriminate use of cellphones within the Orthopaedics, could increase the risk of infection. This study aimed to measure the contamination of cellphones of health care workers (HCW's) in a South African tertiary hospital. Secondarily was to investigate the cellphone hygiene behaviour of HCW's.

A prospective cross-sectional study was conducted in June 2022. Samples were taken from the the participant's cellphones under an aseptic technique and sent for microbiology. The participants also filled out a questionnaire on cellphone behaviour. The inclusion criteria was orthopaedic HCW's working in the institution; This included nurses and doctors in the orthopaedic theatres and main orthopaedic wards.

Sixty-two participants were included; 54 from Orthopaedics and 7 from Anaesthesia. From the samples, 71% grew pathogens while 30,64% grew two or more colonies. This is slightly lower than other studies which showed contamination up to 100%. Micro-organisms cultured included Staphylococcus species; S.Epidermidis, Methycillin sensitive S.aureas; and E.Coli. Cellphone hygiene behaviour was also better than most other studies in terms of frequency of cleaning the devices and hand hygiene around cellphone usage. This which may be a contributing factor to the lower micro-organism contamination.

This study should be the first of many as we have identified that there are indeed pathogens on cellphones transferable to patients; causing sepsis. Though cellphones have become vital in patients management in the hospital setting, factors such as improvement in cellphone hygiene through education and frequent cleaning of cellphones will aid in disabling the negative impact of cellphones in the orthopaedic environment.
CRITICAL BONE DEFECT AFFECTING THE OUTCOME OF MANAGEMENT IN ANATOMICAL TYPE IV CHRONIC OSTEOMYELITIS
Authors: Tsang Jerry , Epstein Gadi , Ferreira Nando
Published: November 2023

The Cierny and Mader classification assists with decision-making in the management of osteomyelitis by strafying the host status and the pathoanatomy of disease. However the anatomical type IV represents a heterogenous group with regards to treatment requirements and outcomes. We propose that modification of the Cierny and Mader anatomical classification with an additional type V classifier (diffuse corticomedullary involvement with an associated critical bone defect) will allow more accurate stratification of patients and tailoring of treatment strategies.

A retrospective review of 83 patients undergoing treatment for Cierny and Mader anatomical type IV osteomyelitis of the appendicular skeleton at a single centre was performed.

Risk factors for the presence of a critical bone defect were female patients (OR 3.1 (95% CI 1.08– 8.92)) and requirement for soft tissue reconstruction (OR 3.35 (95% CI 1.35–8.31)); osteomyelitis of the femur was negatively associated with the presence of a critical bone defect (OR 0.13 (95% CI 0.03–0.66)). There was no statistical significant risk of adverse outcomes (failure to eradicate infection or achieve bone union) associated with the presence of a critical-sized bone defect. The median time to bone union was ten months (95% CI 7.9–12.1 months). There was a statistically significant difference in the median time to bone union between cases with a critical bone defect (12.0 months (95% 10.2–13.7 months)) and those without (6.0 months (95% CI 4.8–7.1 months))

This study provided evidence to support the introduction of a new subgroup of the Cierny and Mader anatomical classification (Type V). Using a standardised approach to management, comparable early outcomes can be achieved in patients with Cierny and Mader anatomical type V osteomyelitis.

However, to achieve a successful outcome, there is a requirement for additional bone and soft tissue reconstruction procedures with an associated increase in treatment time.
PATTERNS OF INJURY AND TREATMENT FOR DISTAL RADIUS FRACTURES AT A MAJOR TRAUMA CENTRE

Published: November 2023

Fractures of the distal radius are common, and form a considerable proportion of the trauma workload. We conducted a study to examine the patterns of injury and treatment for adult patients presenting with distal radius fractures to a major trauma centre serving an urban population.

We undertook a retrospective cohort study to identify all patients treated at our major trauma centre for a distal radius fracture between 1 June 2018 and 1 May 2021. We reviewed the medical records and imaging for each patient to examine patterns of injury and treatment. We undertook a binomial logistic regression to produce a predictive model for operative fixation or inpatient admission.

Overall, 571 fractures of the distal radius were treated at our centre during the study period. A total of 146 (26%) patients required an inpatient admission, and 385 surgical procedures for fractures of the distal radius were recorded between June 2018 and May 2021. The most common mechanism of injury was a fall from a height of one metre or less. Of the total fractures, 59% (n = 337) were treated nonoperatively, and of those patients treated with surgery, locked anterior-plate fixation was the preferred technique (79%; n = 180).

The epidemiology of distal radius fractures treated at our major trauma centre replicated the classical bimodal distribution described in the literature. Patient age, open fractures, and fracture classification were factors correlated with the decision to treat the fracture operatively. While most fractures were

Published: November 2023

Sacral fractures are often underdiagnosed, but are frequent in the setting of pelvic ring injuries. They are mostly caused by high velocity injuries or they can be pathological in aetiology. We sought to assess the clinical outcomes of the surgically treated unstable sacral fractures, with or without neurological deficits. unstable sacral fractures were included in the study.

Single centre, prospectively collected data, retrospective review of patients who sustained vertically unstable fractures of the sacrum who underwent surgical fixation. out of a total of 432 patients with pelvis and acetabulum injuries. fifty six patients met the inclusion criteria. 18 patients had sustained zone one injuries. 14 patients had zone 2 injuries and 10 patients had zone 3 injurie. Operative fixation was performed percutaneously using cannulated screws in 18 patients.. Open fixation of the sacrum using the anterior approach in 6 patients. Posterior approach was indicates in all 10 of the zone 3 injuries of the sacrum. While in 4 patients, combined approaches were used. 3 patients had decompression and spinopelvic fixation.

Neurological deficits were present in 16% of the patients. 2 patients presented with neurgenic bladder. Of the 4 patients who had neurological fall out, 3 resolved with posterior decompression and posterior fixation. All 4 neurological deficits were due to taction or compression of the nerve roots. No hardware failures or non unions observed.

The rate of neurological deficit was related more to the degree of pelvic ring instability than to a particular fracture pattern. Low rates of complications and successful surgical treatment of sacral fractures is achiavable. Timeous accurate diagnosis mandatory
A RETROSPECTIVE REVIEW OF THE BACTERIOLOGY OF HAND SEPSIS AT A TERTIARY HOSPITAL IN GAUTENG
Authors: Adams Allyson , Sithebe Hlabane
Published: November 2023

The aim of this investigation is to firstly quantify the burden of disease, and secondly qualify the organisms being cultured during debridement to establish their sensitivities to available antibiotics. This study will also look at the concomitant burden of Human Immunodeficiency Virus (HIV) and Diabetes Mellitus (DM) in cases of hand sepsis, to establish whether these two disease processes require special consideration and treatment tailoring.

The method employed to collect the data will be retrospective collection of patient information, using random sampling. Included patients will be adult patients who undergo debridement and have a sample registered on the National Health Laboratory System (NHLS). The daily intake sheet will be used to collect patients details and these details will then be used to collect results of intra-operative specimens using the NHLS. These patient details will also be used to check patients’ HIV results and HBA1c (Glycated Haemoglobin A1c) results.

Majority of the specimens revealed Methicillin Sensitive Staphylococcus Aureus (MSSA), with a reassuringly low rate of Methicillin Resistant Staphylococcus Aureus (MRSA) when compared to international data. The yield of patients tested for HIV or DM was lower than expected, despite this being the standard of care.

The projected impact of this study will be assessment of the current burden of disease and then clarification of our current management strategy, in order to assess if it would be possible to change to a more cost-effective antibiotic with a narrower spectrum of bacteria coverage. The potential exists to not only implement cost saving measures, but also promote antibiotic stewardship by decreasing the practice of empiric broad-spectrum antibiotic use.
RISK ACCEPTABILITY ASSESSMENT FOR COMPLICATIONS OF FIVE ORTHOPAEDIC PROCEDURES: A QUESTIONNAIRE-BASED STUDY
Authors: Mukiibi Winifred , Aden Abdirashid , Iqbal Nasir
Published: November 2023

Surgeons must explain the risk of complications to prospective patients and get informed consent. If a complication that occurred was omitted in the process or given the wrong risk level, culpability of the surgeon is judged in court against what a “reasonable patient” would like to know to give or refuse consent.

ObjectivesThe concept “reasonable patient” is widely used, no attempt has been made to define it objectively. We assessed insight of patients, presumed “reasonable”, about risks of certain complications after they underwent one of five orthopaedic procedures.

Questionnaire was administered with procedures: femur IMN, tibia IMN, ankle ORIF, distal radius ORIF and hip arthroplasty. Four common/serious complications were chosen per procedure, and matched against life events with documented risk levels.

There were 230 participants 163 males and 67 females. We found 19.1% of patients above age 40 and 33.3% with tertiary education wouldn't accept nerve injury as reported in literature. With infection risk, 18.1% above 40 and 52.9% with pre-tertiary education would not accept. All patients below 40 and 7.4% pre-tertiary education wouldn't accept the risk of death as reported. However, 37.1% above 40 and 76.9% with pre-tertiary education would accept that risk at a higher level.

It is hard to predict what risk of complication a patient may accept. This study highlights that some patients will not accept risks as reported in literature, even though they need the procedure. Therefore, surgeons need to explain complications fully, so that patients knowingly accepts or refuses consent. The subset of patients who are not willing to accept any level of risk, should be the subject of another study.
PRIMARY HIP AND KNEE ARTHROPLASTY AT DISTRICT LEVEL IS SAFE AND MAY REDUCE THE BURDEN ON TERTIARY CARE IN A LOW-INCOME SETTING
Authors: Laubscher Kim , Kauta Ntambue , Held Michael , Nortje Marc , Dey Roopam
Published: November 2023

Arthroplasty procedures in low-income countries are mostly performed at tertiary centers, with waiting lists exceeding 12 to 24 months. Providing arthroplasty services at other levels of healthcare aims to offset this burden, however there is a marked paucity of literature regarding surgical outcomes. This study aims to provide evidence on the safety of arthroplasty at district level.

Retrospective review of consecutive arthroplasty cases performed at a District Hospital (DH), and a Tertiary Hospital (TH) in Cape Town, between January 2015 and December 2018. Patient demographics, hospital length of stay, surgery related readmissions, reoperations, post-operative complications, and mortality rates were compared between cohorts.

Seven hundred and ninety-five primary arthroplasty surgeries were performed at TH level and 228 at DH level. The average hospital stay was 5.2±2.0 days at DH level and 7.6±7.1 days for TH (p<0.05). Readmissions within 3 months post-surgery of 1.75% (4 patients) for district and 4.40% (35) for TH (p<0.05). Reoperation rate of 1 in every 100 patients at the DH and 8.3 in every 100 patients at the TH (p<0.05). Death rate was 0.4% vs 0.6% at district and TH respectively (p>0.05). Periprosthetic joint infection rate was 0.43% at DH and 2.26% at TH. The percentage of hip dislocation requiring revision was 0% at district and 0.37% at TH. During the study period, 228 patients received arthroplasty surgery at the DH; these patients would otherwise have remained on the TH waiting list.

Hip and Knee Arthroplasty at District health care level is safe and may help ease the burden on arthroplasty services at tertiary care facilities in a Southern African context. Adequately trained surgeons should be encouraged to perform these procedures in district hospitals provided there is appropriate patient selection and adherence to strict theatre operating procedures.
WHAT IS THE COMPLIANCE REGARDING THROMBOPROPHYLAXIS IN POSTOPERATIVE ARTHROPLASTY PATIENTS IN A TERTIARY HOSPITAL IN SOUTH AFRICA?
Authors: Almeida Richard , Pietrzak Jurek , Mokete Lipalo , Sikhauli Nkhodiseni
Published: November 2023

Total Joint Arthroplasty (TJA) is a successful orthopaedic procedure allowing dramatic clinical and functional improvements. Globally, there's been an increase in demand and performed cases associated with an increase in complications. Subsequently, focus on the prevention of complications has become important worldwide. The incidence of venous-thrombolic events (VTE) despite great attention has not diminished despite much investigation. A balance between efficacy and safety from the available agents is essential. Low molecular weight heparin (LMWH) has been commonly used, but oral anti-coagulants have become more popular. The aim of this study was to assess the adherence LMWH and the effectiveness and safety of preventing VTE in post-operative arthroplasty patients in a South African setting.

We conducted a prospective cohort study that included hip and knee, primary and revision, arthroplasty patients who received thromboprophylaxis with one daily injection of LMWH for 14 days post discharge. Patients who omitted 1 or more doses during the follow up period were classified as “non adherent”. A questionnaire was used at follow up visits at least 6 weeks post-operatively.

100 consecutive patients were followed up. The mean age of patients was 63.45 years. There were 68 % female patients. There was a 92% compliance rate. 60 % of patients had the injection administered by a family member, 38 % administered it themselves and 2 % had the injection administered by health professionals. Venous thromboembolic events were confirmed in 5 % at 7.86 days after surgery. Three patients had persistent wound drainage after surgery, however, none required reoperation or readmission.

Compliance with LMWH is high and is comparable with oral agents. It is effective in preventing VTE and safe with regards to bleeding and wound complications in a South African setting. Patient education regarding medications may improve compliance of the medication.
TRAINING IN HIP AND KNEE ARTHROPLASTY: ARE THEY DOING ENOUGH?
Authors: Jordaan Koos , Coetzee Kaylem , Charilaou Johan , Jakoet Shafique
Published: November 2023

Orthopaedic surgery is a practical surgical specialization field, the exit exam for registrars remains written and oral. Despite logbook evaluation and surgical work-based assessments, the question remains: can registrars perform elective surgery upon qualification? In South Africa, obstacles to elective surgical training include the trauma workload, financial constraints, fellowships and the Covid pandemic. In hip and knee arthroplasty, new approaches like the direct anterior approach (DAA) and robotic-assisted knee surgery also contributed to the dilution of cases available for registrar training. There are concerns that orthopaedic registrars do not perform enough cases to achieve surgical proficiency.

Review of the last 4 years of registrar logbooks in hip and knee arthroplasty surgery performed in a single tertiary academic hospital in South Africa. We included all primary total hip replacements (THR), total knee replacements (TKR) and hemiarthroplasties (HA) done for neck of femur (NOF) fractures between 1 April 2019 and 30 March 2023. Differentiation between registrar assisting, registrar performing with consultant supervision and registrar performing independent surgery was done.

990 hip arthroplasties (472 Primary THR, 216 NOF THR, 302 NOF HA) and 316 Primary TKR were performed during the study period. In primary elective THR the posterior approach was dominant and used in 76% of cases. In NOF THA the DAA was dominant used in 98% of cases. Primary TKR robotic-assisted technologies was used in 27% (n=94) cases. Registrars as the primary surgeon were the highest in NOF THA at 70% of cases and the lowest performing TKR at 25%. During 3-month rotations, an average registrar performed 12 (2 TKR and 10 THR) and assisted in 35 (10 TKR and 25 THR) cases.

Despite the large number of arthroplasties operations being performed over the last 4-year period, the surgical cases done by registrars are below, the proposed minimal cases to provide surgical proficiency during their training period.
"You Could Speak the Truth with a Tongue of Fire": The Cultural and Political Work of Indigenous Periodicals
Authors: Stanciu Cristina , Scheiding Oliver , Doerfler Jill
Published: November 2023

ABSTRACT: From the nineteenth century to the present, Indigenous periodicals have served as mediators for both complex citational practices and decolonial translations, as well as an important archive documenting and representing Indigenous people and issues. This special issue of the journal American Periodicals brings together scholars working on Indigenous periodicals to provide a glimpse into the vast array of Indigenous periodical writing as continuous repositories of Indigenous knowledge. The contributions highlighted in this special issue, emerging from an MLA roundtable session and a symposium on Indigenous print cultures, show that Indigenous periodicals serve as distinct material carriers of Indigenous information and visual-graphic spaces of communication, knowledge production, and community-building. They are complex media artifacts whose relation to the construction of sovereignty is articulated through periodicity, network, mediator, and archive. As special issue editors, we seek to broaden existing understandings of Indigenous textualities and interpretative traditions by offering a fresh approach to analyzing periodicals and the role they play in the expansion of Indigenous print, while also highlighting Indigenous periodicals' ongoing political and cultural work of sharing diverse viewpoints, expressing identity, establishing and participating in traditions, and asserting sovereignty.
"Keep Up the Fight": Indigenous Editorial Practices, Collaboration, and Networks of Exchange in the Early Twentieth Century
Authors: Zuck Rochelle Raineri
Published: November 2023

ABSTRACT: This essay explores how Indigenous editors such as Carlos Montezuma (Yavapai), Rev. Philip Gordon (Anishinaabe), and Gus, Theo, and Rev. Clement H. Beaulieu (Anishinaabe) created communities of practice that sought to use the press as a tool to advance what they believed to be the best interests of Indigenous peoples and define the role of the Indigenous editor in the early twentieth century. I first situate these editors and publishers within widening Indigenous periodical networks of the early twentieth century before moving on to discuss their editorial practices and collaborations. Ultimately, I argue that editors such as Montezuma, Gordon, and the Beaulieus sought to leverage Indigenous periodical networks to intervene in massmedia representations of Indigenous people and create spaces for intertribal dialogue that were not mediated by the BIA or white "friends of the Indian."
Indian Territory Reimagined: Ora Eddleman Reed's Twin Territories
Authors: Carpenter Cari
Published: November 2023

ABSTRACT: Twin Territories was a newspaper in Indian Territory from 1898 to 1905 that included the latest regional news, historical information about various tribes, and the column "What the Curious Want to Know." It also incorporated a variety of photographs of American Indian women, portraits of officials, and landmarks. The newspaper actively sustained a national audience. Ora Eddleman Reed understood her role as an editor in Indian Territory in part as a responsibility to correct inaccurate, dangerous representations of Natives people in the US. In addition to countering stereotypes of women, Twin Territories troubled visions of a backwards civilization, offering instead a portrait of Cherokee people as members of a burgeoning capitalist economy. While concentrating on a particular vision of Indian Territory as a modern, developing space, I seek to place Twin Territories in context as an Indian Territory newspaper of the turn of the twentieth century and to study its key features, including the advice column, its short fiction, and the photographic column, "Portraits of Indian Girls." Such representation is all the more complicated by Eddelman Reed's connection to the Cherokee community.
Exceptional Whites, Bad Jews: Racial Subjectivity, Anti-Zionism, and the Jewish New Left
Authors: Balthaser Benjamin
Published: November 2023

Abstract: It is often assumed that the 1967 Arab-Israeli War led to the "wholesale conversion of the Jews to Zionism," as Norman Podhoretz famously phrased it. This "conversion" is equally, if often less explicitly, said to coincide with the end of the era of Jewish marginality in the U.S. and West more broadly, as Jews of European descent were half-included, half-conscripted, into normative structures of whiteness, class ascension, and citizenship. While this epochal shift in Jewish racial formation and political allegiance is undeniable especially in the context of large Jewish secular and religious institutions, at the time this "conversion" was seen as anything but inevitable. Many Jewish liberals, including Irving Howe, Seymour Lipset, and Nathan Glazer, and reactionaries such as Meir Kahane, saw Jewish overrepresentation and hypervisibility in New Left organizations such as Students for a Democratic Society, the Youth International Party, and the Socialist Workers Party as a sign that Jewish youth rejected Zionism as well as the Jewish rise into the middle class. That retrospectively we see Jewish racial formation and political alignment after 1967 as a fait accompli often relies on the erasure not only of mass Jewish participation in the New Left, but also the erasure of the New Left's anti-imperialist political commitments, including critique of expansive Israeli militarism and the settler colonial assumptions underlying Zionism. Looking at memoirs, pamphlets, histories, and original interviews with Jewish participants in the New Left, this article excavates the political alignments of Jewish New Left activists, exploring opposition to the U.S.'s new support of the Israeli state as well as the changing Ashkenazi Jewish racial assignment. Rather than finding Third World and Black Power critiques of Israel antisemitic, it was precisely the Jewish New Left's politics of international and multiracial solidarity that encouraged their support for Black Power critiques of Zionism. In this way, Jewish members of the New Left also attempted to critically challenge their own whiteness, aligning support for Israel after 1967 with support for the racial and economic structures of militarism and capitalism at home.
Hagar's Prayer in the Desert and Great Bracha in the High: A Dissenting and Decentralizing Voice in Israeli Poetry
Authors: Hasan-Rokem Galit
Published: November 2023

Abstract: This essay addresses the power of poetry to express dissenting voices in a society that demands ideological unity in the name of collective survival. The revival of Hebrew has been intimately associated with Zionist cultural politics. However, Hebrew poetry has continuously challenged the dominant ideological precepts of the political movements of Zionism. This essay focuses on reading the poetry of Bracha Serri, a feminist poet who was born in Sanaa, Yemen in 1940 and passed away in Jerusalem in 2013. The religious education of her childhood, her academic studies, and the period she spent in Northern California have inspired the unabashed and highly original feminist voice of her poems. Her religious idiom powerfully revolutionizes the patriarchal hierarchies embodied in traditional Jewish religion and produces an innovative religious language which not only addresses a divine female figure in traditional sacred language but also boldly shatters the boundaries of gender. Finally, it also uplifts the poet herself from an oppressed position dictated by gender hierarchy as well as the ethnic injustices characterizing Israeli society. Serri was not afraid to shock and to attack dominant norms. Not only is her poetry antimilitaristic but it also identifies the common interests of Palestinian women and Mizrahi Israeli women, as well as women in general. In her poetic language, she also admiringly incorporates associations from the Black struggle in the United States. Her choice to avoid publishing her poetry at leading Israeli publishing houses and journals and to instead publish most of her literary work by herself was not merely an act of dissent, but also constituted an act of decentralization by establishing a center of her own that resisted the dominant centers of power. Serri's poetry is a particularly beautiful, moving, forceful, and important voice among the voices critically responding to Zionism.
The Russo-Ukrainian War and Implications for Nuclear Nonproliferation in the Middle East
Authors: Cigar Norman
Published: November 2023

ABSTRACT: The Russo-Ukrainian War has provided observers in the Middle East with lessons learned about nuclear issues and, in particular, about the implications of Ukraine's earlier denuclearization. This study addresses whether the conclusions drawn in the region contribute positively or negatively to non-proliferation. Although regional policymakers have said little on this sensitive issue, the media on which this study relies is controlled by the state in most Middle Eastern countries and reflects official policy and thus, indirectly, can provide insights into the thinking of policymakers in existing or potential nuclear states. The study concludes there is a regional consensus that Ukraine's denuclearization was a mistake and that Russia's nuclear status gives it an advantage, thus reinforcing existing paradigms on the effectiveness of nuclear deterrence and increasing scepticism about the reliability of international security guarantees as a substitute for one's own nuclear arsenal. The likely result will be a more challenging situation for nonproliferation efforts in the Middle East. To enhance the prospect for non-proliferation, the international community should promote a less threatening security environment, with less rhetoric about external regime change or invasion, and offer credible security guarantees for those who disarm or agree not to seek nuclear weapons.

Published: November 2023

The Karner blue butterfly (Lycaeides melissa samuelis, or Kbb), a federally endangered species under the U.S. Endangered Species Act in decline due to habitat loss, can be further threatened by climate change. Evaluating how climate shapes the population trend of the Kbb can help in the development of adaptive management plans. Current demographic models for the Kbb incorporate in either a density-dependent or density-independent manner. We instead created mixed density-dependent and -independent (hereafter “endo-exogenous”) models for Kbbs based on long-term count data of five isolated populations in the upper Midwest, United States during two flight periods (May to June and July to August) to understand how the growth rates were related to previous population densities and abiotic environmental conditions, including various macro- and micro-climatic variables. Our endo-exogenous extinction risk models showed that both density-dependent and -independent components were vital drivers of the historical population trends. However, climate change impacts were not always detrimental to Kbbs. Despite the decrease of population growth rate with higher overwinter temperatures and spring precipitations in the first generation, the growth rate increased with higher summer temperatures and precipitations in the second generation. We concluded that finer spatiotemporally scaled models could be more rewarding in guiding the decision-making process of Kbb restoration under climate change.
Resumos da 6ª Mostra do Doutoramento em Psicologia

Published: November 2023

A afirmação da Faculdade de Psicologia e de Ciências da Educação da Universidade de Coimbra (FPCE-UC) passa por uma aposta na investigação de excelência e pela consolidação de uma cultura científica que, desde cedo, promova a interação dos/as estudantes com as suas estruturas de investigação (Centro de Investigação, Laboratórios, Observatório). A valorização do desenvolvimento de competências transversais no percurso formativo é também a aposta de uma formação universitária em estreita ligação com a investigação. Neste enquadramento, a Mostra de Doutoramento em Psicologia assume uma especial importância enquanto iniciativa de promoção e valorização da investigação realizada na área da Psicologia na FPCE-UC. Esta Mostra é, também, um espaço privilegiado para a apresentação, pelos/as estudantes, dos seus projetos de doutoramento, quando numa mais fase inicial do seu percurso, e para a apresentação pública dos resultados dos seus projetos, oferecendo-lhes uma experiência em tudo idêntica ao de um congresso científico. E porque a Mostra de Doutoramento em Psicologia se insere no âmbito de uma unidade curricular do curso de Doutoramento em Psicologia (“Competências Científicas Transversais”), esta iniciativa possibilita o treino de apresentação de comunicações científicas, mas também o debate e a partilha de conhecimento numa lógica “multidisciplinar”, no denominador comum que é a Psicologia.
Integer Programming Based Optimization of Power Consumption for Data Center Networks
Authors: Kovásznai Gergely , Nsaif Mohammed
Published: November 2023

With the quickly developing data centers in smart cities, reducing energy consumption and improving network performance, as well as economic benefits, are essential research topics. In particular, Data Center Networks do not always run at full capacity, which leads to significant energy consumption. This paper experiments with a range of optimization tools to find the optimal solutions for the Integer Linear Programming (ILP) model of network power consumption. The study reports on experiments under three communication patterns (near, long, and random), measuring runtime and memory consumption in order to evaluate the performance of different ILP solvers.While the results show that, for near traffic pattern, most of the tools rapidly converge to the optimal solution, CP-SAT provides the most stable performance and outperforms the other solvers for the long traffic pattern. On the other hand, for random traffic pattern, Gurobi can be considered to be the best choice, since it is able to solve all the benchmark instances under the time limit and finds solutions faster by 1 or 2 orders of magnitude than the other solvers do.

Nivel del desarrollo de sitios web desde la perspectiva del marketing en la gestión pública: un estudio de los portales digitales municipales de la provincia de Buenos Aires (Argentina)
Authors: Iparraguirre Camila , Vigier Hernán Pedro , Gorjup María Tatiana
Published: November 2023

El presente trabajo explora los sitios web de los 135 municipios de la provincia de Buenos Aires, con el objetivo de analizar su nivel de desarrollo actual desde la óptica del marketing público. La recolección de datos se hizo en base a una planilla de observación desarrollada sobre el modelo de dimensiones de e-servicios municipales de Esteves (2005) con adaptaciones propuestas por la Cátedra AG Software (2006) en su estudio de páginas web municipales en Argentina, resultando la herramienta elaborada una de las contribuciones de la investigación. De los resultados obtenidos se desprende que los sitios web están más desarrollados en cuanto a las dimensiones Interacción, Presencia, Transacción e Información Urbana, y menos desarrollados en las dimensiones Transparencia y E-democracia. Y en concordancia con los estudios de Esteves (2005) y la Catedra AG Software (2006), se observa que no hay un crecimiento sostenible y por fases.
